Perceived risk to a health problem is formed by inferential rules called heuristics and by comparative judgments that assess how one's risk compares to the risk of others. The purpose of this cross-sectional, community-based survey was to examine how experiences with breast cancer, knowledge of risk factors, and specific heuristics inform risk judgments for oneself, for friends/peers, and comparative judgments for breast cancer (risk friends/peers - risk self). We recruited an English-speaking, multicultural (57% nonwhite) sample of 184 middle-aged (47 + or - 12 years old), well-educated women. Fifty percent of participants perceived that their breast cancer risk was the same as the risk of their friends/peers; 10% were pessimistic (risk friends/peers - risk self < 0), whereas 40% were optimistic (risk friends/peers - risk self > 0). Family history of breast cancer and worry informed risk judgments for oneself. The availability and cultural heuristics specific for black women informed risk judgments for friends/peers. Knowledge of risk factors and interactions of knowledge with the availability, representativeness, and simulation heuristics informed comparative judgments (risk friends/peers - risk self). We discuss cognitive mechanisms with which experiences, knowledge, and heuristics influence comparative breast cancer risk judgments. Risk communication interventions should assess knowledge deficits, contextual variables, and specific heuristics that activate differential information processing mechanisms.

The specific aims of increasing Resilience to Natural Hazards in China programme are (i) to improve hazard forecasting, risk mitigation and preparedness based upon reliable knowledge of the fundamental processes involved and underpinned by basic science and, (ii) to improve the uptake of and responses to scientific advice, by developing risk-based approaches to natural hazards in collaboration with the communities at risk. One of the programme's principal goals is to integrate natural and social science research to increase the benefits for those affected by natural hazards. To that end a co-productive approach to research is expected, involving a framework for sharing knowledge and values between natural and social scientists and consultation with policy makers, civil society and other stakeholders. This paper explore knowledge relationships and reflective learning across disciplines. There is commonly a disjunction between the evolution and provision of expert knowledge and its effective utilisation. Building on experience as Strategic Advisor to the Increasing Resilience to Natural Hazards programme, this paper addresses the research needs to assess how scientific knowledge and risk reduction strategies can be most effectively developed and communicated.

Objective Compare feedback strategies in three versions of an educational game. Participants Study abroad students (N = 482) participated by playing the game and completing pre-game/post-game surveys January-March 2010. Methods This study employed an experimental design. Primary outcome measures were knowledge gain, player-satisfaction, and risk perception. Results One-third had previously traveled to a malaria-risk region and two-thirds planned to do so. Baseline malaria knowledge was low. Post-game knowledge and risk perception were significantly higher than pre-game, irrespective of past travel status. The group that automatically received explanatory feedback following game decisions scored higher for mean knowledge gain, without differences in player-satisfaction. Conclusions The challenges of designing a feedback strategy to support Web-based learning make these results highly relevant to health educators developing interactive multimedia interventions. The increasing number of students traveling to higher-risk destinations demands attention. Both malaria-naive and malaria-experienced students would benefit from this approach to travel health education. PMID:22686363

2018-02-01

Local knowledge in disaster management should not be neglected in developing community resilience. The circular relation between humans and their living habitat and community social relation have developed the local knowledge namely specialized knowledge, shared knowledge, and common knowledge. Its correlation with community-based disaster management has become an important discussion specially to answer can local knowledge underlie community-based disaster risk reduction concept development? To answer this question, this research used mix-method. Interview and crosstab method for 73 respondents with 90% trust rate were used to determine the correlation between local knowledge and community characteristics. This research found out that shared knowledge dominated community local knowledge (77%). While common knowledge and specialized knowledge were sequentially 8% and 15%. The high score of shared value (77%) indicated that local knowledge was occurred in household level and not yet indicated in community level. Shared knowledge was found in 3 phases of the resilient community in dealing with disaster, namely mitigation, emergency response, and recovery phase. This research, therefore, has opened a new scientific discussion on the self-help concept in community-help concept in CBDRM concept development in Indonesia.

Industrial accidents are among the most known challenges to business continuity. Many organisations have lost their reputation following devastating accidents. To manage the risks of such accidents, it is necessary to accumulate sufficient knowledge regarding their roots, causes and preventive techniques. The required knowledge might be obtained through various approaches, including databases. Unfortunately, many databases are hampered by (among other things) static data presentations, a lack of semantic features, and the inability to present accident knowledge as discrete domains. This paper proposes the use of Protégé software to develop a knowledge base for the domain of explosion accidents. Such a structure has a higher capability to improve information retrieval compared with common accident databases. To accomplish this goal, a knowledge management process model was followed. The ontological explosion knowledge base (EKB) was built for further applications, including process accident knowledge retrieval and risk management. The paper will show how the EKB has a semantic feature that enables users to overcome some of the search constraints of existing accident databases.

Objective Unintentional drowning is the most common cause of childhood death in rural China. Global intervention efforts offer mixed results regarding the efficacy of educational programs. Methods Using a randomized controlled design, we evaluated a testimonial-based intervention to reduce drowning risk among 280 3rd- and 4th-grade rural Chinese children. Children were randomly assigned to view either testimonials on drowning risk (intervention) or dog-bite risk (control). Safety knowledge and perceived vulnerability were measured by self-report questionnaires, and simulated behaviors in and near water were assessed with a culturally appropriate dollhouse task. Results Children in the intervention group had improved children’s safety knowledge and simulated behaviors but not perceived vulnerability compared with controls. Conclusions The testimonial-based intervention’s efficacy appears promising, as it improved safety knowledge and simulated risk behaviors with water among rural Chinese children.

Background Subjective risk factor perception is an important component of the motivation to change unhealthy life styles. While prior studies assessed cardiovascular risk factor knowledge, little is known about determinants of the individual perception of stroke risk. Methods Survey by mailed questionnaire among 1483 participants of a prior public stroke campaign in Germany. Participants had been informed about their individual stroke risk based on the Framingham stroke risk score. Stroke risk factor knowledge, perception of lifetime stroke risk and risk factor status were included in the questionnaire, and the determinants of good risk factor knowledge and high stroke risk perception were identified using logistic regression models. Results Overall stroke risk factor knowledge was good with 67–96% of the participants recognizing established risk factors. The two exceptions were diabetes (recognized by 49%) and myocardial infarction (57%). Knowledge of a specific factor was superior among those affected by it. 13% of all participants considered themselves of having a high stroke risk, 55% indicated a moderate risk. All major risk factors contributed significantly to the perception of being at high stroke risk, but the effects of age, sex and education were non-significant. Poor self-rated health was additionally associated with high individual stroke risk perception. Conclusion Stroke risk factor knowledge was high in this study. The self perception of an increased stroke risk was associated with established risk factors as well as low perception of general health. PMID:17371603

2016-01-01

Abstract Background and Purpose: Heart disease is the leading killer of women and remains poorly recognized in high-risk groups. We assessed baseline knowledge gaps and efficacy of a survey-based educational intervention. Methods: Four hundred seventy-two women in clinical settings completed pre-/post-surveys for knowledge of: heart disease as the leading killer, risk factors (general and personal levels), heart attack/stroke symptoms, and taking appropriate emergency action. They received a clinic-based educational intervention delivered by healthcare professionals in the course of their clinical care. Change score analyses tested pre-/post-differences in knowledge after the educational intervention, comparing proportions by race, ethnicity, and urban/nonurban status. Results: Knowledge and awareness was low in all groups, especially for American Indian women (p < 0.05). Awareness was overall highest for heart disease as the leading killer, but it was the lowest for taking appropriate action (13% of Hispanic, 13% of American Indian, 29% of African American, and 18% of nonurban women; p < 0.05). For all women, knowledge of the major risk factors was low (58%) as was knowledge of their personal levels for risk factors (73% awareness for hypertension, 54% for cholesterol, and 50% for diabetes). The intervention was effective (% knowledge gain) in all groups of women, particularly for raising awareness of: (1) heart disease as the leading killer in American Indian (25%), Hispanic (18%), and nonurban (15%) women; (2) taking appropriate action for American Indian (80%), African American (64%), non-Hispanic (55%), and urban (56%) women; (3) heart disease risk factors for Hispanic (56%) and American Indian (47%) women; and (4) heart disease and stroke symptoms in American Indian women (54% and 25%, respectively). Conclusions: Significant knowledge gaps persist for heart disease in high-risk women, suggesting that these gaps and groups should be targeted by educational programs. We specify areas of need, and we demonstrate efficacy of a clinic-based educational intervention that can be of utility to busy healthcare professionals. PMID:27356155

Because of the increasing pressures exerted on soil, below-ground life is under threat. Knowledge-based rankings of potential threats to different components of soil biodiversity were developed in order to assess the spatial distribution of threats on a European scale. A list of 13 potential threats to soil biodiversity was proposed to experts with different backgrounds in order to assess the potential for three major components of soil biodiversity: soil microorganisms, fauna, and biological functions. This approach allowed us to obtain knowledge-based rankings of threats. These classifications formed the basis for the development of indices through an additive aggregation model that, along with ad-hoc proxies for each pressure, allowed us to preliminarily assess the spatial patterns of potential threats. Intensive exploitation was identified as the highest pressure. In contrast, the use of genetically modified organisms in agriculture was considered as the threat with least potential. The potential impact of climate change showed the highest uncertainty. Fourteen out of the 27 considered countries have more than 40% of their soils with moderate-high to high potential risk for all three components of soil biodiversity. Arable soils are the most exposed to pressures. Soils within the boreal biogeographic region showed the lowest risk potential. The majority of soils at risk are outside the boundaries of protected areas. First maps of risks to three components of soil biodiversity based on the current scientific knowledge were developed. Despite the intrinsic limits of knowledge-based assessments, a remarkable potential risk to soil biodiversity was observed. Guidelines to preliminarily identify and circumscribe soils potentially at risk are provided. This approach may be used in future research to assess threat at both local and global scale and identify areas of possible risk and, subsequently, design appropriate strategies for monitoring and protection of soil biota.

While many lifestyle-related cancer risk factors including tobacco use, poor diet, and sun exposure are well recognized by the general public, the role of physical activity in decreasing cancer risk is less recognized. Studies have demonstrated gender-, race/ethnicity-, and age-based disparities in cancer risk factor knowledge; however, beliefs and geographic factors that may be related to knowledge are under-examined. In this study, we analyzed data from the 2008 Health Information National Trends Survey to determine correlates of knowledge of the relationship between physical activity and reduced cancer risk in the adult US population. We generated geographic information system maps to examine the geographic distribution of this knowledge. Results revealed that there is confusion among US adults about the relationship between physical activity and cancer risk: Respondents who believed that cancer is not preventable had significantly lower odds of knowing that physical activity reduces cancer risk (p < .001) whereas respondents who believed that cancer is caused by one's behavior had almost two times the odds of knowing that physical activity reduces cancer risk (p < .001). Those who were aware of current physical activity guidelines were also significantly more likely to know that physical activity reduces cancer risk (p < .01). Observed geographic variability in knowledge was consistent with geographic trends in obesity and physical inactivity. Correlates of cancer risk factor knowledge point to opportunities for targeted interventions.

Risk stratification using genetic and other types of personal information could improve current best available approaches to ovarian cancer risk reduction, improving identification of women at increased risk of ovarian cancer and reducing unnecessary interventions for women at lower risk. Amounts of information given to women may influence key informed decision-related outcomes, e.g. knowledge. The primary aim of this study was to compare informed decision-related outcomes between women given one of two versions (gist vs. extended) of a decision aid about stratified ovarian cancer risk-management. This was an experimental survey study comparing the effects of brief (gist) information with lengthier, more detailed (extended) information on cognitions relevant to informed decision-making about participating in risk-stratified ovarian cancer screening. Women with no personal history of ovarian cancer were recruited through an online survey company and randomised to view the gist (n = 512) or extended (n = 519) version of a website-based decision aid and completed an online survey. Primary outcomes were knowledge and intentions. Secondary outcomes included attitudes (values) and decisional conflict. There were no significant differences between the gist and extended conditions in knowledge about ovarian cancer (time*group interaction: F = 0.20, p = 0.66) or intention to participate in ovarian cancer screening based on genetic risk assessment (t(1029) = 0.43, p = 0.67). There were also no between-groups differences in secondary outcomes. In the sample overall (n = 1031), knowledge about ovarian cancer increased from before to after exposure to the decision aid (from 5.71 to 6.77 out of a possible 10: t = 19.04, p < 0.001), and 74% of participants said that they would participate in ovarian cancer screening based on genetic risk assessment. No differences in knowledge or intentions were found between women who viewed the gist version and women who viewed the extended version of a decision aid about risk-stratified ovarian cancer screening. Knowledge increased for women in both decision aid groups. Further research is needed to determine the ideal volume and type of content for decision aids about stratified ovarian cancer risk-management. This study was registered with the ISRCTN registry; registration number: ISRCTN48627877 .

Origins of Secure Base Script Knowledge and the Developmental Construction of Attachment Representations

Increasing evidence suggests that attachment representations take at least two forms—a secure base script and an autobiographical narrative of childhood caregiving experiences. This study presents data from the first 26 years of the Minnesota Longitudinal Study of Risk and Adaptation (N = 169), examining the developmental origins of secure base script knowledge in a high-risk sample, and testing alternative models of the developmental sequencing of the construction of attachment representations. Results demonstrated that secure base script knowledge was predicted by observations of maternal sensitivity across childhood and adolescence. Further, findings suggest that the construction of a secure base script supports the development of a coherent autobiographical representation of childhood attachment experiences with primary caregivers by early adulthood.

There is an urgent need for broad and integrated studies that address the risks of engineered nanomaterials (ENMs) along the different endpoints of the society, environment, and economy (SEE) complex adaptive system. This article presents an integrated science-based methodology to assess the potential risks of engineered nanomaterials. To achieve the study objective, two major tasks are accomplished, knowledge synthesis and algorithmic computational methodology. The knowledge synthesis task is designed to capture "what is known" and to outline the gaps in knowledge from ENMs risk perspective. The algorithmic computational methodology is geared toward the provision of decisions and an understanding of the risks of ENMs along different endpoints for the constituents of the SEE complex adaptive system. The approach presented herein allows for addressing the formidable task of assessing the implications and risks of exposure to ENMs, with the long term goal to build a decision-support system to guide key stakeholders in the SEE system towards building sustainable ENMs and nano-enabled products.

As a population, persons with serious mental illness (SMI) have an elevated risk for HIV infection. However, relatively little is known about how the risk of HIV has affected their lives, how persons with SMI evaluate their HIV risk, and what preventive measures they undertake. Furthermore, relatively little is known about community-based HIV prevention for persons with SMI as most interventions have been restricted to clinical settings. This report presents findings on the HIV-related experiences of persons with SMI living in supportive housing programs, one possible setting for implementing community-based HIV prevention with this population. The qualitative investigation interviewed 41 men and women living in five supportive housing programs. In-depth, qualitative interviews elicited discussion of research participants’ (a) experiences with HIV, (b) knowledge about HIV and HIV prevention, (c) assessments of their own risk, (d) descriptions of how they apply their prevention knowledge, and (e) reports of barriers for HIV prevention. Research participants describe social networks that have substantial contact with persons affected by HIV. However, contrary to some expectations of persons with SMI, research participants report using HIV prevention knowledge in negotiating their risk of contracting HIV. The implications of these findings are discussed in terms of their relevance for implementing community-based HIV prevention for persons with SMI. PMID:16389505

To identify whether university students who have both food-safety knowledge and beliefs perform risk-reduction behaviors. Cross-sectional research using a questionnaire that included food-safety knowledge, perceptions, risk-reduction behavior, stages for the selection of safer food based on the Transtheoretical Model, and demographic characteristics. Four universities in eastern Japan and 2 universities in western Japan. University students (n = 799). Food-safety knowledge, beliefs, and risk-reduction behaviors. Answers on measures assessing risk perception and food-safety knowledge were combined to form 4 groups of participants. Relationships among demographic characteristics, the 4 groups, risk-reduction behaviors, stage of change, and severity and susceptibility were assessed. The proportion of students who had more knowledge of food safety and a belief that "there are no 100% safe food items" was high in the group that frequently performed risk-reduction behaviors, as it was in the group who had taken a basic class about food or health care and who had, or were working toward, a food or nutrition qualification. University students who thought that there were no 100% safe food items and who had more knowledge about food safety were more likely to confirm food-safety information when selecting food.

Knowledge about oral cancer risk factors and signs is thought to improve prevention and early diagnosis, and in turn, increases survival. In this population-based survey, knowledge about oral cancer was assessed in Iran. A total of 1800 self-administered questionnaires (collecting sociodemographic data and questions regarding oral cancer risk factors and signs) were distributed through random sampling. Final scores ranged between 0 and 15 for the risk factors and 0-11 for the signs. Scores below the median indicated a low level of knowledge, scores representing the third quartile of correct answers indicated a moderate level of knowledge, and scores representing the upper quartile indicated a high level of knowledge. Statistical tests were used for analysis of knowledge level in different sociodemographic categories. A total of 1312 participants completed the questionnaires. The average of knowledge scores for risk factors was 5.3 ± 3.0 and for signs was 4.5 ± 2.9. Overall, 75 and 56% respectively were able to identify major risk factors (smoking and alcohol); 23.5% could not define any related signs and symptoms. Dividing scores into quartiles indicated that three out of four people had "low" knowledge about risk factors and 58% had "low" knowledge about signs and symptoms. Females and highly educated people had more knowledge of oral cancer. Significant difference was found between job and level of knowledge (P = 0.001). This survey revealed that public knowledge of oral cancer was not satisfactory in Iran. Efforts should be done to inform and educate people with risk factors, initial clinical presentation, and symptoms, in order to improve prevention and promote early diagnosis.

Unintentional drowning is the most common cause of childhood death in rural China. Global intervention efforts offer mixed results regarding the efficacy of educational programs. Using a randomized controlled design, we evaluated a testimonial-based intervention to reduce drowning risk among 280 3rd- and 4th-grade rural Chinese children. Children were randomly assigned to view either testimonials on drowning risk (intervention) or dog-bite risk (control). Safety knowledge and perceived vulnerability were measured by self-report questionnaires, and simulated behaviors in and near water were assessed with a culturally appropriate dollhouse task. Children in the intervention group had improved children's safety knowledge and simulated behaviors but not perceived vulnerability compared with controls. The testimonial-based intervention's efficacy appears promising, as it improved safety knowledge and simulated risk behaviors with water among rural Chinese children. © The Author 2015.

Results are given about neural network testing on the data of both bankrupt and financially strong enterprises, which were not included into training and test sets.

Indigenous knowledge management to enhance community resilience to tsunami risk: lessons learned from Smong traditions in Simeulue island, Indonesia

NASA Astrophysics Data System (ADS)

Rahman, A.; Sakurai, A.; Munadi, K.

2017-02-01

Knowledge accumulation and production embedded in communities through social interactions meant that the Smong tradition of indigenous knowledge of tsunami risk successfully alerted people to the 2004 tsunami, on the island of Simeulue, in Aceh, Indonesia. Based on this practical example, an indigenous management model was developed for Smong information. This knowledge management method involves the transformation of indigenous knowledge into applicable ways to increase community resilience, including making appropriate decisions and taking action in three disaster phases. First, in the pre-disaster stage, the community needs to be willing to mainstream and integrate indigenous knowledge of disaster risk reduction issues into related activities. Second, during disasters, the Smong tradition should make the community able to think clearly, act based on informed decisions, and protect themselves and others by using their indigenous knowledge. Last, in the post-disaster phase, the community needs to be strong enough to face challenges and support each other and “building back better” efforts, using local resources. The findings for the Smong tradition provide valuable knowledge about community resilience. Primary community resilience to disasters is strongly related to existing knowledge that triggers appropriate decisions and actions during pre-disaster, disaster, and post-disaster phases.

Integration of expert knowledge and uncertainty in natural risk assessment

NASA Astrophysics Data System (ADS)

Baruffini, Mirko; Jaboyedoff, Michel

2010-05-01

Natural hazards occurring in alpine regions during the last decades have clearly shown that interruptions of the Swiss railway power supply and closures of the Gotthard highway due to those events have increased the awareness of infrastructure vulnerability also in Switzerland and illustrate the potential impacts of failures on the performance of infrastructure systems. This asks for a high level of surveillance and preservation along the transalpine lines. Traditional simulation models are only partially capable to predict complex systems behaviours and the subsequently designed and implemented protection strategies are not able to mitigate the full spectrum of risk consequences. They are costly, and maximal protection is most probably not economically feasible. In addition, the quantitative risk assessment approaches such as fault tree analysis, event tree analysis and equivalent annual fatality analysis rely heavily on statistical information. Collecting sufficient data to base a statistical probability of risk is costly and, in many situations, such data does not exist; thus, expert knowledge and experience or engineering judgment can be exploited to estimate risk qualitatively. In order to overcome the statistics lack we used models based on expert's knowledge in order to qualitatively predict based on linguistic appreciation that are more expressive and natural in risk assessment. Fuzzy reasoning (FR) can be used providing a mechanism of computing with words (Zadeh, 1965) for modelling qualitative human thought processes in analyzing complex systems and decisions. Uncertainty in predicting the risk levels arises from such situations because no fully-formalized knowledge are available. Another possibility is to use probability based on triangular probability density function (T-PDF) that can be used to follow the same flow-chart as FR. We implemented the Swiss natural hazard recommendations FR and probability using T-PDF in order to obtain hazard zoning and uncertainties. We followed the same approach for each term of risks i.e. hazard, vulnerability, element at risk, exposition. This risk approach can be achieved by a comprehensive use of several artificial intelligence (AI) technologies, which are done through, for example: (1) GIS techniques; (2) FR or T-PDF for qualitatively predicting risks for possible review results; and (3) A Multi-Criteria Evaluation for analyzing weak points. The main advantages of FR or T-PDF involve the ability to express not-fully-formalized knowledge, easy knowledge representation and acquisition, and self updatability. The results show that such an approach points out quite wide zone of uncertainty. REFERENCES Zadeh L.A. 1965 : Fuzzy Sets. Information and Control, 8:338-353.

Background The study aimed to i) assess nutritional knowledge in female athletes susceptible to the Female Athlete Triad (FAT) syndrome and to compare with controls; and ii) to compare nutritional knowledge of those who were classified as being 'at risk' for developing FAT syndrome and those who are 'not at risk'. Methods In this study, participants completed General Nutritional Knowledge Questionnaire (GNKQ), the Eating Attitude Test (EAT-26) and survey measures of training/physical activity, menstrual and skeletal injury history. The sample consisted of 48 regional endurance athletes, 11 trampoline gymnasts and 32 untrained controls. Based on proxy measures for the FAT components, participants were classified being 'at risk' or 'not at risk' and nutrition knowledge scores were compared for the two groups. Formal education related to nutrition was considered. Results A considerably higher percentage of athletes were classified 'at risk' of menstrual dysfunction than controls (28.8% and 9.4%, respectively) and a higher percentage scored at or above the cutoff value of 20 on the EAT-26 test among athletes than controls (10.2% and 3.1%, respectively). 8.5% of athletes were classified 'at risk' for bone mineral density in contrast to none from the control group. Nutrition knowledge and eating attitude appeared to be independent for both athletes and controls. GNKQ scores of athletes were higher than controls but the differences between the knowledge of 'at risk' and 'not at risk' athletes and controls were inconsequential. Formal education in nutrition or closely related subjects does not have an influence on nutrition knowledge or on being classified as 'at risk' or 'not at risk'. Conclusion The lack of difference in nutrition knowledge between 'at risk' and 'not at risk' athletes suggests that lack of information is not accountable for restricted eating associated with the Female Athlete Triad.

Based on the characteristics of e-commerce of fresh agricultural products in China, and using the correlation analysis method, the relational model between product knowledge, perceived benefit, perceived risk and purchase intention is constructed. The Logistic model is used to carry in the empirical analysis. The influence factors and the mechanism of online purchase intention are explored. The results show that consumers’ product knowledge, perceived benefit and perceived risk can affect their purchase intention. Consumers’ product knowledge has a positive effect on perceived benefit and perceived benefit has a positive effect on purchase intention. Consumers’ product knowledge has a negative effect on perceived risk, and perceived profit has a negative effect on perceived risk, and perceived risk has a negative effect on purchase intention. Through the empirical analysis, some feasible suggestions for the government and electricity supplier enterprises can be provided.

Awareness and Knowledge of Child and Adolescent Risky Behaviors: A Parent's Perspective.

Ahern, Nancy R; Kemppainen, Jeanne; Thacker, Paige

2016-04-01

Adolescence is a developmental stage marked by risk-taking and limited comprehension of dangers of risky behaviors. Previous research has focused on adolescents' perspective of risk with little evidence on parents' knowledge regarding risk. This qualitative study examined parental knowledge and perspectives of child/teen risk behaviors associated with salvia, sexting, inhalant use/abuse, and self/participant-assisted choking. A sample of 30 parents of children/teens aged 10-17 completed a self-administered survey based on Flanagan's critical incident technique. Data were analyzed according to Flanagan's guidelines. Two advanced practice nurses determined category reliability with 95% agreement. The survey yielded five categories of parental responses to potential risky behaviors in their child/teen including the following: talking to my children, setting up consequences, confronting the child, seeking help, and talking to others. Although the majority of the parents were aware of newer behaviors, less than one half of the participants reported discussing risks with their child/teen. One third reported that their child knew a friend who was thinking about/tried sexting. One quarter of parents reported that they were not monitoring their child/teen's media use. Study findings provide important implications for developing an evidence-based education intervention to improve parents' awareness, knowledge, and identification of risk behaviors in their children/teens. © 2016 Wiley Periodicals, Inc.

South Africa is in the midst of a devastating HIV-AIDS epidemic and most new HIV infections occur among young adults and adolescents. The current study examined risk behaviors and HIV risk factors among young people living in a Black South African township. Using community-based outreach methods of street intercept and facility-based surveying, 113 men and 115 women age 25 and younger responded to an anonymous survey. Results showed that men (68%) and women (56%) reported HIV-related high risk sexual behaviors. Although knowledge about HIV transmission was generally high, there was evidence that misconceptions about AIDS persist, particularly myths related to HIV transmission. For young men, HIV risk factors were associated with fewer years of education, lower levels of AIDS-related knowledge, condom attitudes, and Dagga (marijuana) use. Among young women, HIV risk factors were associated with beliefs that condoms get in the way of sex and rates of unprotected vaginal intercourse. Despite adequate general AIDS knowledge and risk sensitization, South African youth demonstrated high rates of sexual practices that place them at risk for HIV infection. There is an urgent need for behavioral interventions targeted to young South Africans living in the most economically disadvantaged areas.

Education-based disparities in knowledge of novel health risks: The case of knowledge gaps in HIV risk perceptions.

Risk perception is a key determinant of preventive health behaviour, but when asked, some individuals indicate they do not know their health risk. Low education is associated with both lack of knowledge about health risk and with the persistence and exacerbation of gaps in knowledge about health issues. This study uses the context of an emerging infectious disease threat to explore the hypothesis that the education-don't know risk relation results from differences in knowledge about the health issue of interest. Specifically, we examine whether patterns of change over time follow theoretical predictions that disparities in risk knowledge would increase over time in less educated sectors of the population (knowledge gap hypothesis). Secondary analysis of population-representative behavioural surveillance survey. We analysed data from the 1993 to 2000 Behavior Risk Factor Surveillance System surveys, which measured education and perceived HIV/AIDS risk in a population sample collected separately in each survey year; don't know responses were coded. In each year, individuals with higher education were less likely to respond don't know. The absolute prevalence of don't know responding dropped over time; nonetheless, there was an increase over time in the magnitude of the pattern of lower education being associated with greater don't know responding. We found support for the knowledge gap hypothesis. Over time, populations with greater education gained more knowledge about their HIV risk than populations with lower education. Results highlight the need to carefully consider health communication strategies to reach and address those individuals with low education and health knowledge. Statement of contribution What is already known on this subject? A meaningful potion of the population answers 'don't know' when asked to report their risk for health problems, indicating a lack of risk perception in the domain. Previous studies have shown that level of education is associated with don't know responding - those with lower educational attainment are more likely to respond don't know. The education-don't know responding relation suggests that lack of health information and health domain knowledge might be a factor in lacking risk perception, but this mechanism has not been previously tested. What does this study add? Patterns of changes in don't know responding over time as population-level knowledge of a health risk increase are consistent with the health information/health knowledge hypothesis outlined above. As population knowledge of HIV/AIDS risk in the United States increased over time (indicated by declining overall rates of don't know responses), the relation of education level to don't know responding actually became stronger. The pattern of change over time is the classic 'knowledge gap hypothesis' pattern, which has not been previously demonstrated for knowledge of personal health risk. The knowledge gap response pattern supports the health information/health knowledge hypothesis. © 2018 The British Psychological Society.

The incidence of human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC) is increasing in the United States and may be underestimated among black individuals. Characterizing the current knowledge level among black individuals is critical to developing interventions to increase awareness. To describe the sociodemographic correlates of knowledge and risk perception of HPV and HPV-associated OPSCC among a predominantly black population. A cross-sectional survey was conducted at a drag racing event on September 12 and 13, 2015, in Madison, Illinois. The setting was a community-based oral head and neck cancer screening and education initiative. Participants were 301 drag race attendees 18 years or older who were conveniently sampled from attendees at an annual drag racing event predominantly patronized by black individuals. The primary outcome was knowledge and risk perception of HPV and HPV-associated OPSCC. An electronic-based questionnaire elicited sociodemographic information and contained oral cancer knowledge and risk perception items, which were combined to form knowledge and risk perception scores. Multivariable linear regression analysis assessed estimates of knowledge and risk perception of HPV and HPV-associated OPSCC. Of the 301 participants (111 female and 190 male) completing the questionnaire, 194 (64.5%) were black. Overall, respondents ranged in age from 18 to 78 years, with a mean (SD) age of 48.0 (13.0) years. The mean (SD) knowledge score was 5.7 (4.6) of 15, and the mean (SD) risk perception score was 2.2 (1.4) of 6. Using multivariable linear regression, we found that, for every 1-year increase in age, knowledge of HPV-associated OPSCC decreased by 5.0% and was worse in men (β = -1.26; 95% CI, -2.33 to -0.18), black vs white individuals (β = -1.29; 95% CI, -2.35 to -0.23), and those with a high school diploma or less vs college graduates (β = -3.23; 95% CI, -4.67 to -1.80). Black individuals also had lower perceived risk of developing HPV-associated OPSCC (β = -0.36; 95% CI, -0.69 to -0.02) compared with white individuals, and participants with a high school diploma or less had lower perceived risk of developing HPV-associated OPSCC compared with those with a college degree or higher (β = -0.59; 95% CI, -1.04 to -0.14). Age and sex were independent correlates of knowledge of HPV-associated OPSCC, while race and education level were correlates of both knowledge and risk perception of HPV-associated OPSCC. These findings should inform future interventions targeted at increasing knowledge of HPV-associated OPSCC in black communities.

Origins of Secure Base Script Knowledge and the Developmental Construction of Attachment Representations.

Increasing evidence suggests that attachment representations take at least two forms: a secure base script and an autobiographical narrative of childhood caregiving experiences. This study presents data from the first 26 years of the Minnesota Longitudinal Study of Risk and Adaptation (N = 169), examining the developmental origins of secure base script knowledge in a high-risk sample and testing alternative models of the developmental sequencing of the construction of attachment representations. Results demonstrated that secure base script knowledge was predicted by observations of maternal sensitivity across childhood and adolescence. Furthermore, findings suggest that the construction of a secure base script supports the development of a coherent autobiographical representation of childhood attachment experiences with primary caregivers by early adulthood. © 2016 The Authors.

Hewner, Sharon; Seo, Jin Young; Gothard, Sandra E; Johnson, Barbara J

2014-01-01

Risk-stratified care management requires knowledge of the complexity of chronic disease and comorbidity, information that is often not readily available in the primary care setting. The purpose of this article was to describe a population-based approach to risk-stratified care management that could be applied in primary care. Three populations (Medicaid, Medicare, and privately insured) at a regional health plan were divided into risk-stratified cohorts based on chronic disease and complexity, and utilization was compared before and after the implementation of population-specific care management teams of nurses. Risk-stratified care management was associated with reductions in hospitalization rates in all three populations, but the opportunities to avoid admissions were different. Knowledge of population complexity is critical to the development of risk-stratified care management in primary care, and a complexity matrix can help nurses identify gaps in care and align interventions to cohort and population needs.

To assess non-medical university students' knowledge and perceived risk of developing oral cavity and oropharyngeal cancer. A cross-sectional survey was conducted among non-medical students of a private Midwestern university in the United States in May 2012. Questionnaire assessed demographic information and contained 21 previously validated questions regarding knowledge and perceived risk of developing oral cavity and oropharyngeal cancer. Knowledge scale was categorized into low and high. Risk level was estimated based on smoking, drinking, and sexual habits. Bivariate associations between continuous and categorical variables were assessed using Pearson correlation and Chi-square tests, respectively. The response rate was 87% (100 out of 115 students approached). Eighty-one percent (81%) had low oral cavity and oropharyngeal cancer knowledge; and only 2% perceived that their oral cavity and oropharyngeal cancer risk was high. Risk perception was negatively correlated with age at sexual debut, r (64) = -0.26, p = 0.037; one-way ANOVA showed a marginally significant association between risk perception and number of sexual partners, F(4, 60) = 2.48, p = 0.05. There was no significant association between knowledge and perception of risk; however, oral cavity and oropharyngeal cancer knowledge was significantly associated with frequency of prevention of STDs (p < 0.05). Although 86% had heard about oral cavity and oropharyngeal cancer, only 18% had heard of oral mouth examination, and 7% of these reported ever having an oral cavity and oropharyngeal cancer exam. Oral cavity and oropharyngeal cancer knowledge and risk perception is low among this student population. Since oral cavity and oropharyngeal cancer incidence is increasingly shifting towards younger adults, interventions must be tailored to this group in order to improve prevention and control.

Worldwide, more than 50 million cases of dengue fever are reported every year in at least 124 countries, and it is estimated that approximately 2.5 billion people are at risk for dengue infection. In Bangladesh, the recurrence of dengue has become a growing public health threat. Notably, knowledge and perceptions of dengue disease risk, particularly among the public, are not well understood. Recognizing the importance of assessing risk perception, we adopted a comparative approach to examine a generic methodology to assess diverse sets of beliefs related to dengue disease risk. Our study mapped existing knowledge structures regarding the risk associated with dengue virus, its vector (Aedes mosquitoes), water container use, and human activities in the city of Dhaka, Bangladesh. "Public mental models" were developed from interviews and focus group discussions with diverse community groups; "expert mental models" were formulated based on open-ended discussions with experts in the pertinent fields. A comparative assessment of the public's and experts' knowledge and perception of dengue disease risk has revealed significant gaps in the perception of: (a) disease risk indicators and measurements; (b) disease severity; (c) control of disease spread; and (d) the institutions responsible for intervention. This assessment further identifies misconceptions in public perception regarding: (a) causes of dengue disease; (b) dengue disease symptoms; (c) dengue disease severity; (d) dengue vector ecology; and (e) dengue disease transmission. Based on these results, recommendations are put forward for improving communication of dengue risk and practicing local community engagement and knowledge enhancement in Bangladesh. © 2015 Society for Risk Analysis.

A population-based cervical cancer screening program using visual inspection with acetic acid was launched in Maldives in 2014. Our study aimed to assess the knowledge, attitude and practices of women in relation to risk factors of cervical cancer, early detection of the disease and its prevention. The questionnaire based survey was conducted among 20 to 50 year old women, systematically sampled to represent three regions of Maldives. Trained investigators interviewed a total of 2,845 women at home. The prevalence of the risk factors of cervical cancer like early age at marriage and childbirth, multiple marriages, multiple marriages of the husbands, and multiple pregnancies was high. More women knew about breast cancer than cervical cancer. Even among the small number of women who knew of cervical cancer, only 34.6% had the knowledge of at least one early symptom. Very few women knew that the cancer could be prevented by any test. Only 6.2% of the women reported having ever undergone a Pap smear. Many women had the misconception that cervical cancer was infectious. In Maldives the younger women have high literacy rate due to the policy of universal free education and those with higher levels of education had improved knowledge of cervical cancer and its risk factors. The prevalence of risk factors also reduced with improved literacy. Awareness about risk factors and prevention of cervical cancer is limited among Maldivian women in spite of having high exposure to some of the risk factors. A universal literacy program in the country has helped to improve the knowledge of cervical cancer prevention and to reduce the exposure to various risk factors in the younger population.

Heart attack is one of the serious illnesses and reported as the main killer disease. Early prevention is significant to reduce the risk of having the disease. The prevention efforts can be strengthen through awareness and education about risk factor and healthy lifestyle. Therefore the knowledge dissemination is needed to play role in order to distribute and educate public in health care management and disease prevention. Since the knowledge dissemination in medical is important, there is a need to develop a knowledge based system that can emulate human intelligence to assist decision making process. Thereby, this study utilized hybrid artificial intelligence (AI) techniques to develop a Fuzzy Expert System for Diagnosing Heart Attack Disease (HAD). This system integrates fuzzy logic with expert system, which helps the medical practitioner and people to predict the risk and as well as diagnosing heart attack based on given symptom. The development of HAD is expected not only providing expert knowledge but potentially become one of learning resources to help citizens to develop awareness about heart-healthy lifestyle.

The Toxic Truth About Carbon Nanotubes in Water Purification: a Perspective View.

Without nanosafety guidelines, the long-term sustainability of carbon nanotubes (CNTs) for water purifications is questionable. Current risk measurements of CNTs are overshadowed by uncertainties. New risks associated with CNTs are evolving through different waste water purification routes, and there are knowledge gaps in the risk assessment of CNTs based on their physical properties. Although scientific efforts to design risk estimates are evolving, there remains a paucity of knowledge on the unknown health risks of CNTs. The absence of universal CNT safety guidelines is a specific hindrance. In this paper, we close these gaps and suggested several new risk analysis roots and framework extrapolations from CNT-based water purification technologies. We propose a CNT safety clock that will help assess risk appraisal and management. We suggest that this could form the basis of an acceptable CNT safety guideline. We pay particular emphasis on measuring risks based on CNT physico-chemical properties such as diameter, length, aspect ratio, type, charge, hydrophobicity, functionalities and so on which determine CNT behaviour in waste water treatment plants and subsequent release into the environment.

Introduction Cardiovascular diseases (CVDs) are the most common cause of non-communicable disease mortality in sub-Saharan African (SSA) countries. Gaps in knowledge of CVD conditions and their risk factors are important barriers in effective prevention and treatment. Yet, evidence on the awareness and knowledge level of CVD and associated risk factors among populations of SSA is scarce. This review aimed to synthesize available evidence of the level of knowledge of and perceptions towards CVDs and risk factors in the SSA region. Methods Five databases were searched for publications up to December 2016. Narrative synthesis was conducted for knowledge level of CVDs, knowledge of risk factors and clinical signs, factors influencing knowledge of CVDs and source of health information on CVDs. The review was registered with Prospero (CRD42016049165). Results Of 2212 titles and abstracts screened, 45 full-text papers were retrieved and reviewed and 20 were included: eighteen quantitative and two qualitative studies. Levels of knowledge and awareness for CVD and risk factors were generally low, coupled with poor perception. Most studies reported less than half of their study participants having good knowledge of CVDs and/or risk factors. Proportion of participants who were unable to identify a single risk factor and clinical symptom for CVDs ranged from 1.8% in a study among hospital staff in Nigeria to a high of 73% in a population-based survey in Uganda and 7% among University staff in Nigeria to 75.1% in a general population in Uganda respectively. High educational attainment and place of residence had a significant influence on the levels of knowledge for CVDs among SSA populations. Conclusion Low knowledge of CVDs, risk factors and clinical symptoms is strongly associated with the low levels of educational attainment and rural residency in the region. These findings provide useful information for implementers of interventions targeted at the prevention and control of CVDs, and encourages them to incorporate health promotion and awareness campaigns in order to enhance knowledge and awareness of CVDs in the region.

The rate of colorectal cancer (CRC) screening remains relatively low. One potential barrier to higher rates is the lack of physician knowledge regarding CRC screening. The purpose of this study was to assess physicians' knowledge of (a) American Cancer Society (ACS) CRC screening guidelines for average-risk and high-risk patients, and (b) general colorectal cancer facts which support these guidelines. We administered a questionnaire to internal medicine residents, internal medicine attendings and medical students who provide care to patients in a low-income, predominantly minority community, to compare their levels of knowledge regarding CRC screening. Mean knowledge scores were calculated based on the number of correct responses. Knowledge of ACS guidelines for average-risk patients was low, although it did increase directly with level of training: medical students obtained a mean score of 32%, residents 49%, and attendings 56% (p<0.001). Knowledge scores for high-risk patients were even lower, with fewer than half of the respondents offering correct answers. Mean knowledge scores of general CRC screening facts increased with level of training: medical students scored 31%, residents 38% and attendings 42% (p<0.001). Knowledge of CRC screening guidelines for both average- and high-risk patients was suboptimal among the medical students, residents and attendings studied. Lack of knowledge about CRC is one barrier to screening that may contribute to underutilization of screening for minority populations. Further educational efforts should be targeted to these health care professionals.

Ovarian cancer is usually diagnosed at a late stage when outcomes are poor. Personalised ovarian cancer risk prediction, based on genetic and epidemiological information and risk stratified management in adult women could improve outcomes. Examining health care professionals' (HCP) attitudes to ovarian cancer risk stratified management, willingness to support women, self-efficacy (belief in one's own ability to successfully complete a task), and knowledge about ovarian cancer will help identify training needs in anticipation of personalised ovarian cancer risk prediction being introduced. An anonymous survey was distributed online to HCPs via relevant professional organisations in the UK. Kruskal-Wallis tests and pairwise comparisons were used to compare knowledge and self-efficacy scores between different types of HCPs, and attitudes toward population-based genetic testing and risk stratified management were described. Content analysis was undertaken of free text responses concerning HCPs willingness to discuss risk management options with women. One hundred forty-six eligible HCPs completed the survey: oncologists (31%); genetics clinicians (30%); general practitioners (22%); gynaecologists (10%); nurses (4%); and 'others'. Scores for knowledge of ovarian cancer and genetics, and self-efficacy in conducting a cancer risk consultation were generally high but significantly lower for general practitioners compared to genetics clinicians, oncologists, and gynaecologists. Support for population-based genetic testing was not high (<50%). Attitudes towards ovarian cancer risk stratification were mixed, although the majority of participants indicated a willingness to discuss management options with patients. Larger samples are required to investigate attitudes to population-based genetic testing for ovarian cancer risk and to establish why some HCPs are hesitant to offer testing to all adult female patients. If ovarian cancer risk assessment using genetic testing and non-genetic information including epidemiological information is rolled out on a population basis, training will be needed for HCPs in primary care to enable them to provide appropriate support to women at each stage of the process.

Many studies have explored the risk perception of frequent business travelers (FBT) toward malaria. However, less is known about their knowledge of other infectious diseases. This study aimed to identify knowledge gaps by determining the risk perception of FBT toward 11 infectious diseases. Our retrospective web-based survey assessed the accuracy of risk perception among a defined cohort of FBT for 11 infectious diseases. We used logistic regression and the chi-square test to determine the association of risk perception with source of travel advice, demographic variables, and features of trip preparation. Surveys were returned by 63% of the 608 self-registered FBT in Rijswijk, and only the 328 completed questionnaires that adhered to our inclusion criteria were used for analysis. The majority (71%) sought pre-travel health advice and used a company health source (83%). Participants seeking company travel health advice instead of external had significantly more accurate risk knowledge (p = 0.03), but more frequently overestimated typhoid risk (odds ratio = 2.03; 95% confidence interval = 1.23-3.34). While underestimation of disease risk was on average 23% more common than overestimation, HIV risk was overestimated by 75% of FBT. More accurate knowledge among FBT seeking company health advice demonstrates that access to in-company travel clinics can improve risk perception. However, there is an obvious need for risk knowledge improvement, given the overall underestimation of risk. The substantial overestimation of HIV risk is probably due to both public and in-company awareness efforts. Conversely, typhoid risk overestimation was statistically associated with seeking company health advice, and therefore specifically reflects the high focus on typhoid fever within Shell's travel clinic. This study serves as a reminder that a knowledge gap toward infectious diseases besides malaria still exists. Our article will explore the future requirements for more targeted education and research among FBT in companies worldwide. © 2012 International Society of Travel Medicine.

Mapping the knowledge base for maritime health: 3 illness and injury in seafarers.

PubMed

Carter, Tim

2011-01-01

Recent studies of illness and injury in seafarers and of disease risk factors have been mapped. There is a good knowledge base on some aspects of health, especially on causes of death. By contrast there are very few studies on aspects of current importance, such as illness at sea, the scope for its prevention, and its treatment and outcome. Results are presented in terms of the settings in which the investigations were conducted: medical fitness examinations at recruitment and periodically, illness and injury at sea, telemedical advice, evacuation and urgent port referrals, repatriations, illness at other times in serving seafarers, health related cessation of work, and illness after cessation of work. Mortality studies were mapped in a similar way, as were population-based surveys of health and of risk factors. The scope for valid extrapolation of the results from studies in other populations to seafarers is discussed. A more immediate problem of extrapolation relates to the current knowledge base, which is largely derived from own nationality seafarers of the traditional developed world maritime nations. It is uncertain whether this can be validly extrapolated to seafarers from the major crewing countries, who come from populations with very different patterns of illness. Existing studies mirror the priorities of those who commissioned them, in that many of the most valid ones relate to the overall lifetime risks of seafaring in developed countries. These enable comparisons to be made with other occupational groups. The major concerns of many interest groups in the maritime sector about health are now focused on the risks within a single contract period and how these can most efficiently be minimized. Studies on this are limited in scope, are of uncertain validity, and are often used for operational purposes rather than entering the scientific literature. Gaps in knowledge about health risks over a relatively short timescale in seafarers from the major crewing countries have been identified, and the uncertainties about extrapolating from studies in traditional maritime nations to the majority of the world's seafarers means that a major redirection of effort is needed if maritime health practice is to have a sound knowledge base on illness and injury risks in the future.

Representing Human Expertise by the OWL Web Ontology Language to Support Knowledge Engineering in Decision Support Systems.

2014-01-01

Clinical decision support systems (CDSSs) often base their knowledge and advice on human expertise. Knowledge representation needs to be in a format that can be easily understood by human users as well as supporting ongoing knowledge engineering, including evolution and consistency of knowledge. This paper reports on the development of an ontology specification for managing knowledge engineering in a CDSS for assessing and managing risks associated with mental-health problems. The Galatean Risk and Safety Tool, GRiST, represents mental-health expertise in the form of a psychological model of classification. The hierarchical structure was directly represented in the machine using an XML document. Functionality of the model and knowledge management were controlled using attributes in the XML nodes, with an accompanying paper manual for specifying how end-user tools should behave when interfacing with the XML. This paper explains the advantages of using the web-ontology language, OWL, as the specification, details some of the issues and problems encountered in translating the psychological model to OWL, and shows how OWL benefits knowledge engineering. The conclusions are that OWL can have an important role in managing complex knowledge domains for systems based on human expertise without impeding the end-users' understanding of the knowledge base. The generic classification model underpinning GRiST makes it applicable to many decision domains and the accompanying OWL specification facilitates its implementation.

The level of knowledge and awareness of skin cancer risks in parents of young children is largely unknown. The Erlangen Kindergarten study, which enrolled 3,129 parents of 3- to 6-year-old children in southern Germany, addressed this. The population-based survey found an overall high level of knowledge about skin cancer risks and strong support for the necessity of sun protection but identified two areas (role of intermittent sun exposure, sun protection on cloudy summer days) offering a target for improvement in future public health campaigns. © 2015 Wiley Periodicals, Inc.

To review the literature regarding the incidence, current practice, guideline recommendations, nursing management, and knowledge gaps relevant to vesicant extravasation. Published research articles, books, case reports, and national guidelines. Vesicant extravasation is a relatively rare but significant complication of chemotherapy administration. Extravasation may have a range of consequences that can cause serious physical and quality-of-life effects. Knowledge of risk factors and preventive measures can reduce patient risk. Data-based and empirical management strategies such as immediate local measures (agent withdrawal, comfort measures, and medical interventions) may minimize risk for extravasation, as well as lead to timely recognition and management and decreased morbidity should extravasation occur. Vesicant extravasation and sequelae constitute a complex patient problem that clinicians should strive to prevent or to minimize injury should it occur. To this end, clinicians must demonstrate awareness of risks and use specialized knowledge while administering vesicant agents. Only nurses knowledgeable about extravasation and skilled in associated techniques should assume responsibility for vesicant administration.

Race and HIV are intertwined in complex ways. African Americans, particularly those residing in the southern United States, are at great risk for contracting and subsequently transmitting HIV. Research on the extent to which members of this population understand the risks associated with engaging in specific behaviors is limited. This paper examines HIV knowledge among at-risk adult African American men and women and the factors associated with levels of HIV knowledge. Based on a conceptual model derived from Social Disorganization Theory and Syndemics Theory, interviews were conducted between 2009 and 2011. Questionnaire-based interviews were conducted with 1,864 respondents from 80 strategically-chosen census block groups in Atlanta, Georgia. An innovative approach to assessing amount of HIV knowledge was implemented, to derive better estimates of the extent of knowledge. Overall, HIV knowledge was low (average=43.5% correct answers). Seven factors were identified as contributing uniquely to having higher levels of knowledge about HIV transmission: (1) younger age, (2) being educated beyond the high school level, (3) being gay, lesbian or bisexual, (4) experiencing sexual abuse during childhood and/or adolescence, (5) drinking alcohol less frequently, (6) knowing a larger number of HIV-infected persons and (7) knowing anyone currently living with "full blown" AIDS. HIV educational and intervention programs targeting at-risk African American adults need to develop effective ways of bolstering a solid understanding of how HIV is/not transmitted. In particular, efforts need to be targeted toward older adults, those with lower levels of educational attainment and persons who are not acquainted with anyone who is HIV-infected.

FoodWiki: a Mobile App Examines Side Effects of Food Additives Via Semantic Web.

In this article, a research project on mobile safe food consumption system (FoodWiki) is discussed that performs its own inferencing rules in its own knowledge base. Currently, the developed rules examines the side effects that are causing some health risks: heart disease, diabetes, allergy, and asthma as initial. There are thousands compounds added to the processed food by food producers with numerous effects on the food: to add color, stabilize, texturize, preserve, sweeten, thicken, add flavor, soften, emulsify, and so forth. Those commonly used ingredients or compounds in manufactured foods may have many side effects that cause several health risks such as heart disease, hypertension, cholesterol, asthma, diabetes, allergies, alzheimer etc. according to World Health Organization. Safety in food consumption, especially by patients in these risk groups, has become crucial, given that such health problems are ranked in the top ten health risks around the world. It is needed personal e-health knowledge base systems to help patients take control of their safe food consumption. The systems with advanced semantic knowledge base can provide recommendations of appropriate foods before consumption by individuals. The proposed FoodWiki system is using a concept based search mechanism that performs on thousands food compounds to provide more relevant information.

Hybrid regimes of knowledge? Challenges for constructing scientific evidence in the context of the GMO-debate.

PubMed

Böschen, Stefan

2009-07-01

Over the last two decades, there has been a remarkable shift of attention to the scientific and political fundamentals of the precautionary principle. The application of this principle has become a main strategy of coping with the different forms and problems related to non-knowledge. Thus, societies are increasingly confronted with the challenging and hitherto unresolved problem of political and technological decision-making under conditions of diverging framings of non-knowledge. At present, there seems to be no generally accepted scientific or institutional approach. This is why the fundamental question of how different scientific actors define and construct evidence is not answered yet. Hence, this paper is based on the consideration that the conflicts in risk policy concerning genetically modified organisms (GMO) depend on the unresolved conflicts about the diverging scientific strategies and structures of evidence-making between the epistemic cultures involved. Thus, this study investigates two questions: (1) do the epistemic strategies of evidence-making differ systematically with the scientific actors involved in the GMO-debate? (2) What consequences emerge considering institutionalized procedures of decision-making? This article is based on a secondary analysis of findings and perspectives reported in the literature and on the methods of qualitative social empirical research, i.e., interviews with experts. A total number of 34 interviews were conducted to explore the different strategies of handling non-knowledge and constructing evidence. Actors from science, administration, business and NGOs were interviewed. In this way, typical epistemic cultures can be described. An epistemic culture is the constellation of methodological strategies, theoretical assumptions and practical-experimental settings which define in every speciality the ways how we know what we know. There are two main results. Firstly, it was worked out that the epistemic cultures involved in the GMO-debate use rather distinct strategies to define non-knowledge and to classify evidence. There are three types of constructing evidence, which correspond to different types of epistemic cultures. Secondly, the findings imply that the intensity of the conflicts in risk policy fields like the GMO-debate is due to a lack of knowledge politics. Usually, knowledge politics is restricted to the design of institutional procedures to compile knowledge provided by experts. The institutional setting of risk analysis and risk management is based on the premise of strict separation between knowledge and power. However, inadmissible mixing-up of knowledge and power is observable. It seems that non-knowledge leads to an epistemic no man's land, and, hence, hybrid regimes of knowledge emerge. These regimes are hybrid with respect to the unclear and not explicitly reflected strategies of evidence-making. By lacking of knowledge politics, this situation opens up 'windows of opportunity' for actors with special interests in risk policy fields like the GMO-debate. Therefore, there is a difference between the visible institutionalized structures of risk policies and the rather invisible hybrid regimes of knowledge. Structure and scope of expertise have to be reflected and new instruments of knowledge politics have to be designed. Different epistemic cultures can be qualified by describing their particular strategies of evidence-making. To solve the conflicts between these strategies, a meta-expertise is needed. Besides the institutionalized settings of knowledge politics, the underlying hybrid regimes of knowledge have to be identified. The concept of epistemic cultures and their strategies of evidence-making should be investigated more explicitly with respect to other risk policy fields The analysis of hybrid regimes of knowledge should be deepened by looking at the complex interactions between institutional, discursive and practical rules affecting risk assessment.

Effects of newspaper coverage on public knowledge about modifiable cancer risks.

PubMed

Stryker, Jo Ellen; Moriarty, Cortney M; Jensen, Jakob D

2008-07-01

This study explores the relationship between cancer newspaper coverage and public knowledge about cancer prevention, confirming self-reported associations between news exposure and cancer prevention knowledge with descriptions of newspaper coverage of modifiable cancer risks. Content analyses (N = 954) revealed that newspapers pay relatively little attention to cancer prevention. However, there is greater newspaper attention to tobacco and diet than to exercise, sun, and alcohol. Survey analysis (the National Cancer Institute's Health Information National Trends Survey) revealed that after controlling for differences based on gender, race, age, income, and education, attention to health news was significantly associated with knowledge about cancer risks associated with food and smoking but not for knowledge about exercise, sun, or alcohol. These findings conform to the findings of the content analysis data and provide a validation of a self-reported measure of media exposure, as well as evidence suggesting a threshold below which news coverage may not generate public knowledge about cancer prevention.

The cardioRisk project addresses the development of personalized risk assessment tools for patients who have been admitted to the hospital with acute myocardial infarction. Although there are models available that assess the short-term risk of death/new events for such patients, these models were established in circumstances that do not take into account the present clinical interventions and, in some cases, the risk factors used by such models are not easily available in clinical practice. The integration of the existing risk tools (applied in the clinician's daily practice) with data-driven knowledge discovery mechanisms based on data routinely collected during hospitalizations, will be a breakthrough in overcoming some of these difficulties. In this context, the development of simple and interpretable models (based on recent datasets), unquestionably will facilitate and will introduce confidence in this integration process. In this work, a simple and interpretable model based on a real dataset is proposed. It consists of a decision tree model structure that uses a reduced set of six binary risk factors. The validation is performed using a recent dataset provided by the Portuguese Society of Cardiology (11113 patients), which originally comprised 77 risk factors. A sensitivity, specificity and accuracy of, respectively, 80.42%, 77.25% and 78.80% were achieved showing the effectiveness of the approach.

The Heart Monitor is an object-oriented, knowledge-based system designed to support the clinical activities of cardiovascular (CV) rehabilitation. The original concept was developed as part of graduate research completed in 1992. This paper describes the second generation system which is being implemented in collaboration with a local heart rehabilitation program. The PC UNIX-based system supports an extensive patient database organized by clinical areas. In addition, a knowledge base is employed to monitor patient status. Rule-based automated reasoning is employed to assess risk factors contraindicative to exercise therapy and to monitor administrative and statutory requirements. PMID:8563285

The Shape of Ecosystem Management to Come: Anticipating Risks and Fostering Resilience

PubMed Central

Seidl, Rupert

2014-01-01

Global change is increasingly challenging the sustainable provisioning of ecosystem services to society. Addressing future uncertainty and risk has therefore become a central problem of ecosystem management. With risk management and resilience-based stewardship, two contrasting approaches have been proposed to address this issue. Whereas one is concentrated on anticipating and mitigating risks, the other is focused on fostering the ability to absorb perturbations and maintain desired properties. While they have hitherto been discussed largely separately in the literature, I here propose a unifying framework of anticipating risks and fostering resilience in ecosystem management. Anticipatory action is advocated when the predictability of risk is high and sufficient knowledge to address it is available. Conversely, in situations in which predictability and knowledge are limited, resilience-based measures are paramount. I conclude that, by adopting a purposeful combination of insights from risk and resilience research, we can make ecosystem services provisioning more robust to future uncertainty and change.

An integrated science-based methodology to assess potential ...

EPA Pesticide Factsheets

There is an urgent need for broad and integrated studies that address the risks of engineered nanomaterials (ENMs) along the different endpoints of the society, environment, and economy (SEE) complex adaptive system. This article presents an integrated science-based methodology to assess the potential risks of engineered nanomaterials. To achieve the study objective, two major tasks are accomplished, knowledge synthesis and algorithmic computational methodology. The knowledge synthesis task is designed to capture “what is known” and to outline the gaps in knowledge from ENMs risk perspective. The algorithmic computational methodology is geared toward the provision of decisions and an understanding of the risks of ENMs along different endpoints for the constituents of the SEE complex adaptive system. The approach presented herein allows for addressing the formidable task of assessing the implications and risks of exposure to ENMs, with the long term goal to build a decision-support system to guide key stakeholders in the SEE system towards building sustainable ENMs and nano-enabled products. The following specific aims are formulated to achieve the study objective: (1) to propose a system of systems (SoS) architecture that builds a network management among the different entities in the large SEE system to track the flow of ENMs emission, fate and transport from the source to the receptor; (2) to establish a staged approach for knowledge synthesis methodo

Predicting caries risk in children can be done by identifying caries risk factors. It is an important measure which contributes to best understanding of the cariogenic profile of the patient. Identification could be done by clinical examination and answering the questionnaire. We arrange the study to verify the questionnaire validation for predicting caries risk in children. The study was conducted on 62 pairs of mothers and their children, aged between 3 and 5 years. The questionnaire consists of 10 questions concerning mothers' attitude and knowledge about oral health. The reliability and validity test is based on Cronbach's alpha and correlation coefficient value. All question are reliable (Cronbach's alpha = 0.873) and valid (Corrected item-total item correlation >0.4). Five questionnaires of mother's attitude about oral health and five questionnaires of mother's knowledge about oral health are reliable and valid for predicting caries risk in children.

The objective of this study was to test students' knowledge of cardiovascular disease information and to determine if a carefully structured training program administered to high school students would increase their knowledge about cardiovascular disease and risk factors that are preventable. A pilot study was conducted during which fifty high school students from nine counties in the State of Mississippi were measured for their knowledge of hypertension both at baseline and after the completion of an intervention training activity. There were significant gains in knowledge between the pre-test and the post-test that the students completed. The gains in knowledge indicate that elimination of risk factors is possible if all health care and school-based prevention programs are implemented to positively impact changes in eating and physical activity behaviors. Students' involvement in such activities could translate into significant changes in risk factors at these ages and throughout their lifetime. It is widely accepted that these behavioral changes, if sustained into adulthood, could have the potential to influence cardiovascular risk reduction.

Stroke is a global burden. It is not known whether patients who are most at risk of stroke (recurrent stroke or recurrent transient ischaemic attack) have enough knowledge of stroke risk factors and warning signs. The aim of this study was to assess the knowledge of stroke risk factors and warning signs in this high-risk population. We performed a cross-sectional questionnaire-based study of patients with recurrent stroke or recurrent TIA admitted to Srinagarind Hospital and Khon Kaen Hospital, Thailand. A total of 140 patients were included in the study (age 65.6 ± 11.3 years [mean ± SD], 62 females). Using an open-ended questionnaire, nearly one-third of patients (31.4%) could not name any risk factors for stroke. The most commonly recognized risk factors were hypertension (35%), dyslipidemia (28.6%), and diabetes (22.9%). Regarding stroke warning signs, the most commonly recognized warning signs were sudden unilateral weakness (61.4%), sudden trouble with speaking (25.7%), and sudden trouble with walking, loss of balance, or dizziness (21.4%). Nineteen patients (13.6%) could not identify any warning signs. The results showed that knowledge of stroke obtained from open-ended questionnaires is still unsatisfactory. The healthcare provider should provide structured interventions to increase knowledge and awareness of stroke in these patients.

We evaluated the efficacy of a sexual risk reduction intervention utilizing protection motivation and social cognitive theories to address knowledge, threat and coping appraisals, and condom use intentions among HIV-positive individuals in Nepal. Using a quasi-experimental research design, we assigned 277 participants to intervention (n=146) and control (n=131) groups. The intervention group received six sessions on sexual risk reduction strategies and the control group six sessions on medication adherence, smoking, and mental health. Data were collected at baseline and immediately after the intervention. Results indicate that the sexual risk reduction intervention produced a significant increase in HIV transmission knowledge, perceived threat and coping appraisals, and intentions to use condoms with regular, HIV-positive, and HIV-negative partners. The positive effects of the intervention remained significant after adjusting for baseline scores and other potential confounders. In conclusion, our theory-based sexual risk reduction intervention was effective in improving HIV transmission knowledge, perceived threat and coping appraisals, and condom use intentions. Further studies are needed to evaluate the long-term efficacy of the intervention in increasing protection motivation and maintaining preventive behaviors.

One of NASA's goals for long duration space flight is to maintain acceptable levels of crew health, safety, and performance. One way of meeting this goal is through the Biomedical Risk Assessment Intelligent Network (BRAIN), an integrated network of both human and computer elements. The BRAIN will function as an advisor to flight surgeons by assessing the risk of in-flight biomedical problems and recommending appropriate countermeasures. This paper describes the joint effort among various NASA elements to develop BRAIN and an Infectious Disease Risk Assessment (IDRA) prototype. The implementation of this effort addresses the technological aspects of the following: (1) knowledge acquisition; (2) integration of IDRA components; (3) use of expert systems to automate the biomedical prediction process; (4) development of a user-friendly interface; and (5) integration of the IDRA prototype and Exercise Countermeasures Intelligent System (ExerCISys). Because the C Language, CLIPS (the C Language Integrated Production System), and the X-Window System were portable and easily integrated, they were chosen as the tools for the initial IDRA prototype. The feasibility was tested by developing an IDRA prototype that predicts the individual risk of influenza. The application of knowledge-based systems to risk assessment is of great market value to the medical technology industry.

Aims: To examine the impact of cancer awareness training for community-based health workers on confidence to talk about cancer, and knowledge of cancer risk factors and signs and symptoms. Methods: Community-based health workers from Sandwell, Birmingham and Solihull were invited to take part in one of 14 one-day training workshops. Trainees completed questionnaires at the beginning of the workshop and were followed up one month later. Confidence in talking about cancer was examined. Knowledge of cancer risk factors and signs and symptoms was assessed. Trainees were asked to rate the usefulness of the workshop, whether they would recommend it to others and whether they had put what they had learnt into practice. Results: A total of 187 community-based health workers took part in the workshops, and 167 (89%) completed the one-month follow-up. Considerable improvements were observed in confidence to discuss cancer. For example, the proportion of participants reporting feeling ‘very confident’/‘fairly confident’ in discussing signs and symptoms of cancer increased from 32% to 96% (p < .001). Substantial improvements in trainees’ knowledge were also observed, with 79% of participants correctly identifying 10 out of 11 known risk factors for cancer at one month compared with 21% before training (p < .001). Average (unprompted) recall of cancer signs and symptoms also increased from 2.3 (±1.6) to 2.7 (±1.5), (p = .02). Most trainees (83%) rated the workshop as ‘very useful’, and 89% said they would ‘definitely’ recommend the workshop. Conclusion: The cancer awareness training was reviewed positively by community-based health workers and led to improvements in confidence to talk about cancer, and knowledge of risk factors and warning signs of cancer. It is hoped that raising awareness among this group will help them to communicate and drive behaviour change in the at-risk populations with whom they work. PMID:25169613

Background Washington, D.C. has among the highest rates of sexually transmitted infections (STIs) and unintended pregnancy in the United States. Increasing women’s reproductive health knowledge may help address these reproductive health issues. This analysis assessed whether high-risk pregnant African American women in Washington, D.C. who participated in an intervention to reduce behavioral and psychosocial risks had greater reproductive health knowledge than women receiving usual care. Methods Project DC-HOPE was a randomized controlled trial that included pregnant African American women in Washington, D.C., recruited during prenatal care. Women in the intervention group were provided reproductive health education and received tailored counseling sessions to address their psychosocial and behavioral risk(s) (cigarette smoking, environmental tobacco smoke exposure, depression, and intimate partner violence). Women in the control group received usual prenatal care. Participants completed a 10-item reproductive knowledge assessment at baseline (n=1,044) and postpartum (n=830). Differences in total reproductive health knowledge scores at baseline and postpartum between groups were examined via chi-squared tests. Differences in postpartum mean total score by group were assessed via multiple linear regression. Results Women in both groups and at both time points scored approximately 50% on the knowledge assessments. At postpartum, women in the intervention group had higher total scores compared to women receiving usual care (mean 5.40 [SD 1.60] vs. 5.03 [SD 1.53] out of 10, respectively; p<0.001). Conclusions While intervention participants increased reproductive health knowledge, overall scores remained low. Development of interventions designed to impart accurate, individually tailored information to women may promote reproductive health knowledge among high-risk pregnant African American women residing in Washington, D.C.

From senior school through to consultancy, a plethora of assessments shape medical careers. Multiple methods of assessment are used to discriminate between applicants. Medical selection in the UK appears to be moving increasingly towards non-knowledge-based testing at all career stages. We review the evidence for non-knowledge-based tests and discuss their perceived benefits. We raise the question: is the current use of non-knowledge-based tests within the UK at risk of undermining more robust measures of medical school and postgraduate performance? © 2015 Royal College of Physicians.

A study on knowledge, attitudes and health behaviours regarding Alzheimer's disease among community residents in Tianjin, China.

2015-11-01

What is known on the subject? Several studies have measured the general public's knowledge and attitudes towards Alzheimer's disease; however, much of this work is based on western samples. Due to cultural differences, the western findings may be difficult to generalize to the Chinese general public. In addition, the few studies conducted in China were often restricted to a relatively narrow range of knowledge and attitudes. What this paper adds to existing knowledge? The general public had little knowledge of Alzheimer's disease, especially on the causes, symptoms and risk factors. In terms of attitudes, although the general public held positive attitudes towards persons with Alzheimer's disease, most of them were not sure whether or not to share a diagnosis of Alzheimer's disease with the patient. In daily life, only a low proportion of people kept mentally active. What are the implications for practice? A popularization of a wide range of knowledge about Alzheimer's disease needs to be undertaken, especially focusing on persons with low educational level and emphasizing the causes, symptoms and risk factors. Besides, there is a significant need to draw up evidence-based dietary and lifestyle guidelines for Alzheimer's disease risk reduction. Moreover, health promotion agencies should identify priority groups for Alzheimer's disease risk reduction initiatives, especially those with lower income, a lower level of knowledge on Alzheimer's disease and with chronic diseases. The purpose of this descriptive correlational cross-sectional study was to assess the current level of knowledge, attitudes and health behaviours regarding Alzheimer's disease among community residents in Tianjin, China and to identify factors related to these attributes. A convenience sample of 140 community-dwelling adults aged 20-75 years was selected to complete a researcher-designed questionnaire about Alzheimer's disease-related knowledge, attitudes and health behaviours. The findings revealed that 15.7% of the participants knew the risk factors for Alzheimer's disease. With regard to attitude, 138 participants (98.6%) believed that people with Alzheimer's disease should not be discriminated against, and 55.7% were not sure whether to share a diagnosis of Alzheimer's disease with the patient. In daily life, 28.6% of the participants pursued their interests and hobbies. A lower level of health behaviours was associated with lower income, presence of chronic diseases and a lower level of knowledge about Alzheimer's disease. These findings provide a strong case for population-level risk reduction initiatives to be undertaken, especially among people with lower income, a lower level of knowledge on Alzheimer's disease and with chronic diseases. © 2015 John Wiley & Sons Ltd.

Although information is available for prevention of sexually transmitted infection (STI/HIV), adolescents continue to engage in high risk sexual behavior particularly ethnic minority adolescent women with histories of STI or abuse. A description therefore of STI/HIV knowledge and sexual risk behavior among these women is indicated for modification of prevention efforts for sexual health promotion. African-American (n=94) and Mexican-American (n=465) adolescent women 14-18 years of age were included in the study. Assessments of sexual risk behavior and STI/HIV knowledge among these adolescent women described Mexican-American women as at higher risk of STI, pregnancy, substance use and abuse with lower levels of STI/HIV knowledge, previous HIV testing and perceptions of risk than African-American women. A focus on Mexican-American adolescent women with histories of STI and abuse is indicated for translation of community-based health promotion interventions for amelioration of potential adverse sexual health outcomes among ethnic minority adolescent women. © 2013.

The presented survey investigates risk and exposure perceptions of radio frequency electromagnetic fields (RF EMF) associated with base stations, mobile phones and other sources, the key issue being the interaction between both sets of perceptions. The study is based on a cross-sectional design, and conducted with an online sample of 838 citizens from Portugal. The results indicate that respondents' intuitive exposure perception differs from the actual exposure levels. Furthermore, exposure and risk perceptions are found to be highly correlated. Respondents' beliefs about exposure factors, which might influence possible health risks, is appropriate. A regression analysis between exposure characteristics, as predictor variables, and RF EMF risk perception, as the response variable, indicates that people seem to use simple heuristics to form their perceptions. What is bigger, more frequent and longer lasting is seen as riskier. Moreover, the quality of exposure knowledge is not an indicator for amplified EMF risk perception. These findings show that exposure perception is key to future risk communication.

Children (5 and 6 years old, n = 30) at familial risk of dyslexia received a home-based intervention that focused on phoneme awareness and letter knowledge in the year prior to formal reading instruction. The children were compared to a no-training at-risk control group (n = 27), which was selected a year earlier. After training, we found a small effect on a composite score of phoneme awareness (d = 0.29) and a large effect on receptive letter knowledge (d = 0.88). In first grade, however, this did not result in beneficial effects for the experimental group in word reading and spelling. Results are compared to three former intervention studies in The Netherlands and comparable studies from Denmark and Australia.

In this paper, we present a knowledge based system that combines fuzzy processing with rule-based processing to form an improved decision aid for evaluating risk for life insurance. This application illustrates the use of FuzzyCLIPS to build a knowledge based decision support system possessing fuzzy components to improve user interactions and KBS performance. The results employing FuzzyCLIPS are compared with the results obtained from the solution of the problem using traditional numerical equations. The design of the fuzzy solution consists of a CLIPS rule-based system for some factors combined with fuzzy logic rules for others. This paper describes the problem, proposes a solution, presents the results, and provides a sample output of the software product.

Mind the gap! Lay and medical perceptions of risks associated with the use of alternative treatment and conventional medicine.

2015-01-01

Studies on the widespread use of complementary and alternative medicine (CAM) demonstrate that CAM users base their treatment decisions on both subjective, experience-based knowledge and medical knowledge. The aim of this study was to explore lay and medical risk perceptions associated with CAM and conventional medicine. In this explorative qualitative study, we conducted in-depth interviews with 25 Norwegian CAM users with cancer or multiple sclerosis and 12 doctors. The interviews revealed fundamental differences in risk perceptions influencing treatment decisions and risk communication in a clinical setting. While CAM users considered conventional medicine as potentially risky and related this to experiences of severe adverse effects, CAM was perceived as natural and safe. Doctors' risk perceptions were quite the contrary, mainly because of lack of scientific evidence for CAM as a safe and beneficial treatment option. For the safety of CAM users, such divergent risk perceptions may have far-reaching consequences. CAM users should be taken seriously with their self-perception as decision-makers considering their approaches to experiences, knowledge, and science. An awareness of differing lay and medical risk perceptions associated with CAM and conventional medicine in research, doctor-patient communication, and education of patients and doctors is thus important to optimize patient safety in complex health care systems. © 2015 S.

Influenza is a significant worldwide public health issue. Knowledge and perceptions regarding the flu vaccination are associated with whether individuals obtain the vaccination. The purpose of this study was to examine how such perceptions were related to knowledge and self-efficacy regarding influenza and the flu vaccination in Vietnam and the US. College students (n=932) in Vietnam (n=495) and the US (n=437) completed a self-administered survey regarding knowledge and perceptions of influenza vaccinations in September and October 2016. Vietnamese participants reported significantly lower levels of awareness about flu risk, higher levels of negative attitudes toward flu vaccination, lower levels of knowledge about the flu and vaccination, and lower levels of self-efficacy than US participants. Higher levels of flu and flu vaccination knowledge and self-efficacy regarding general responsible health practices were associated with lower levels of negative perceptions of flu risk and attitudes toward vaccination. At the same time, self-efficacy regarding responsible health practices was associated with higher levels of awareness of flu risk and lower levels of negative attitudes toward vaccination. Self-efficacy regarding exercise was associated with lower levels of perceptions of flu risk and higher levels of negative attitudes toward vaccination. Vietnam could benefit from influenza education based on this comparison with the US. In both countries, knowledge and self-efficacy were found to be important factors influencing perceptions of influenza risk and vaccination.

Guidelines have been issued in 2010 to prevent the spread of emerging extensively resistant bacteria (eXDR), but their implementation is difficult. We aimed to evaluate healthcare workers' (HCW) knowledge and their risk perception to identify barriers to the implementation of guidelines. Semi-structured interviews were conducted at a University Hospital, where case patients are regularly admitted. The interviews focused on HCW's knowledge, risk perception, and challenges met. The evaluation of HCW's knowledge and contagiousness and perception of severity of eXDR carriage were analyzed statistically. Risk perception and opinion about guidelines were analyzed by qualitative description. One hundred and twenty-one HCWs were interviewed. The category of HCW, having searched for information on resistant bacteria, and having taken care of case patients were associated with better knowledge. The HCW category, age, type of unit, seniority, and having taken care of case patients were associated with risk perceptions. Qualitative analysis identified 61 themes. HCWs were extremely concerned by the spread of bacteria within the hospital. The main challenges identified were organizational and communication issues. HCWs reported a lack of knowledge and a lack of resources to implement guidelines. Strategies to improve guidelines implementation must be based on a better availability of resources, better communication, and new educational methods. Copyright © 2017 Elsevier Masson SAS.

2012-07-25

The increasing use of computer-administered risk communications affords the potential to replace static risk graphics with animations that use motion cues to reinforce key risk messages. Research on the use of animated graphics, however, has yielded mixed findings, and little research exists to identify the specific animations that might improve risk knowledge and patients' decision making. To test whether viewing animated forms of standard pictograph (icon array) risk graphics displaying risks of side effects would improve people's ability to select the treatment with the lowest risk profile, as compared with viewing static images of the same risks. A total of 4198 members of a demographically diverse Internet panel read a scenario about two hypothetical treatments for thyroid cancer. Each treatment was described as equally effective but varied in side effects (with one option slightly better than the other). Participants were randomly assigned to receive all risk information in 1 of 10 pictograph formats in a quasi-factorial design. We compared a control condition of static grouped icons with a static scattered icon display and with 8 Flash-based animated versions that incorporated different combinations of (1) building the risk 1 icon at a time, (2) having scattered risk icons settle into a group, or (3) having scattered risk icons shuffle themselves (either automatically or by user control). We assessed participants' ability to choose the better treatment (choice accuracy), their gist knowledge of side effects (knowledge accuracy), and their graph evaluation ratings, controlling for subjective numeracy and need for cognition. When compared against static grouped-icon arrays, no animations significantly improved any outcomes, and most showed significant performance degradations. However, participants who received animations of grouped icons in which at-risk icons appeared 1 at a time performed as well on all outcomes as the static grouped-icon control group. Displays with scattered icons (static or animated) performed particularly poorly unless they included the settle animation that allowed users to view event icons grouped. Many combinations of animation, especially those with scattered icons that shuffle randomly, appear to inhibit knowledge accuracy in this context. Static pictographs that group risk icons, however, perform very well on measures of knowledge and choice accuracy. These findings parallel recent evidence in other data communication contexts that less can be more-that is, that simpler, more focused information presentation can result in improved understanding. Decision aid designers and health educators should proceed with caution when considering the use of animated risk graphics to compare two risks, given that evidence-based, static risk graphics appear optimal.

The objective of this study was to determine whether a web-based education strategy could improve maternal knowledge of placental complications of pregnancy and reduce maternal anxiety in high risk-pregnancies. Prospective study in the Placenta Clinic at Mount Sinai Hospital, Toronto, Ontario. Maternal demographics and Internet usage were recorded at the patient's baseline appointment. Placental knowledge was determined using structured verbal and illustrative assessments. The six-item State-Trait Anxiety Inventory (STAI) was administered to assess baseline maternal anxiety. Women were asked to visit the Placenta Clinic website for a minimum of 15 minutes before their follow-up appointment, at which time their placental knowledge and STAI assessments were repeated. Eighteen women were included in the study. Patient knowledge at the baseline appointment was generally poor (median score 10.5 out of a maximum score of 27, range 1 to 22), with major deficits in basic placental knowledge, placenta previa/increta, and preeclampsia. At the follow-up appointment, placental knowledge was significantly improved (median score 23, range 10 to 27; P < 0.001). Educational status (high school or less vs. college or more) had no effect on either baseline knowledge or knowledge improvement. Maternal anxiety at baseline (median score 12 out of a maximum score of 24, range 6 to 23) was significantly reduced at the follow-up appointment (median score 8.5, range 6 to 20; P = 0.005). Deficits in maternal knowledge of placental complications of pregnancy in high-risk pregnant women were substantial but easily rectified with a disease-targeted web-based educational resource. This intervention significantly improved patient knowledge and significantly reduced maternal anxiety.

Balancing cystic fibrosis (CF) care with demands of normal life is associated with decreased adherence to infection prevention and control (IPC) guidelines. Adults with CF, aged 18-25years, were invited to participate via UK CF Trust social media platforms. An online survey evaluated participants' decision-making in nine clinician-rated vignettes and assessed the perceived influence of infection-related information sources. Participants (n=87, mean 21.4years [SD=2.45]; 75% female) were less likely to engage in the high-risk scenarios, although demonstrated greater awareness of cross-infection than environmental risks. Associations between risk-perception and willingness to participate in five vignette-based hypothetical activities were significant (p<0.05). Thematic analysis emphasised influences of past experience and a need to achieve good quality of life. Knowledge gaps were evident. People with CF make decisions that discriminate between risk-levels but are not always based on robust knowledge. They also show some inclination towards engaging in risky behaviours.

Do school-based health centers improve adolescents' access to health care, health status, and risk-taking behavior?

PubMed

Kisker, E E; Brown, R S

1996-05-01

The purpose of this investigation was to assess the School-Based Adolescent Health Care Program, which provided comprehensive health-related services in 24 school-based health centers. The outcomes evaluation compared a cohort of students attending 19 participating schools and a national sample of urban youths, using logit models to control for observed differences between the two groups of youths. Outcome measures included self-reports concerning health center utilization, use of other health care providers, knowledge of key health facts, substance use, sexual activity, contraceptive use, pregnancies and births, and health status. The health centers increased students' access to health care and improved their health knowledge. However, the estimated impacts on health status and risky behaviors were inconsistent, and most were small and not statistically significant. School-based health centers can increase students' health knowledge and access to health-related services, but more intensive or different services are needed if they are to significantly reduce risk-taking behaviors.

Wagner, Julie; Lacey, Kimberly; Chyun, Deborah; Abbott, Gina

2005-07-01

This paper describes a paper and pencil questionnaire that measures heart disease risk knowledge in people with diabetes. The Heart Disease Fact Questionnaire (HDFQ) is a 25-item questionnaire that was developed to tap into respondents' knowledge of major risk factors for the development of CHD. Approximately half of these items specifically address diabetes-related CHD risk factors. Based on extensive pilot data, the current study analyzed responses from 524 people with diabetes to assess the psychometric properties. The HDFQ is readable to an average 13-year old and imposes little burden. It shows good content and face validity. It demonstrates adequate internal consistency, with Kuder-Richardson-20 formula = 0.77 and good item-total correlations. Item analysis showed a desirable range in P-values. In discriminant function analyses, HDFQ scores differentiated respondents by knowledge of their own cardiovascular health, use of lipid lowering medications, health insurance status, and educational attainment, thus indicating good criterion related validity. This measure of heart disease risk knowledge is brief, understandable to respondents, and easy to administer and score. Its potential for use in research and practice is discussed. Future research should establish norms as well as investigate its test-retest reliability and predictive validity.

To determine the most effective method of delivering training to staff on the management of an obstetric emergency. The research was conducted in a District General Hospital in the UK, delivering approximately 3500 women per year. Thirty-six staff, comprising of junior and senior medical and midwifery staff were included as research subjects. Each of the staff members were put into one of six multi-professional teams. Effectively, this gave six teams, each comprising of six members. Three teaching methods were employed. Lecture based teaching (LBT), simulation based teaching (SBT) or a combination of these two (LAS). Each team of staff were randomly allocated to undertake a full day of training in the management of Post Partum Haemorrhage utilising one of these three teaching methods. Team knowledge and performance were assessed pre-training, post training and at three months later. In addition to this assessment of knowledge and performance, qualitative semi-structured interviews were carried out with 50% of the original cohort one year after the training, to explore anxiety, confidence, communication, knowledge retention, enjoyment and transferable skills. All teams improved in their performance and knowledge. The teams taught using simulation only (SBT) were the only group to demonstrate sustained improvement in clinical management of the case, confidence, communication skills and knowledge. However, the study did not have enough power to reach statistical significance. The SBT group reported transferable skills and less anxiety in subsequent emergencies. SBT and LAS reported improved multidisciplinary communication. Although tiring, the SBT was enjoyed the most. Obstetrics is a high risk speciality, in which emergencies are to some extent, inevitable. Training staff to manage these emergencies is a fundamental principal of risk management. Traditional risk management strategies based on incident reporting and event analysis are reactive and not always effective. Simulation based training is an appropriate proactive approach to reducing errors and risk in obstetrics, improving teamwork and communication, whilst giving the student a multiplicity of transferable skills to improve their performance.

Quality risk management in pharmaceutical development.

Charoo, Naseem Ahmad; Ali, Areeg Anwer

2013-07-01

The objective of ICH Q8, Q9 and Q10 documents is application of systemic and science based approach to formulation development for building quality into product. There is always some uncertainty in new product development. Good risk management practice is essential for success of new product development in decreasing this uncertainty. In quality by design paradigm, the product performance properties relevant to the patient are predefined in target product profile (TPP). Together with prior knowledge and experience, TPP helps in identification of critical quality attributes (CQA's). Initial risk assessment which identifies risks to these CQA's provides impetus for product development. Product and process are designed to gain knowledge about these risks, devise strategies to eliminate or mitigate these risks and meet objectives set in TPP. By laying more emphasis on high risk events the protection level of patient is increased. The process being scientifically driven improves the transparency and reliability of the manufacturer. The focus on risk to the patient together with flexible development approach saves invaluable resources, increases confidence on quality and reduces compliance risk. The knowledge acquired in analysing risks to CQA's permits construction of meaningful design space. Within the boundaries of the design space, variation in critical material characteristics and process parameters must be managed in order to yield a product having the desired characteristics. Specifications based on product and process understanding are established such that product will meet the specifications if tested. In this way, the product is amenable to real time release, since specifications only confirm quality but they do not serve as a means of effective process control.

Linking environmental risk assessment and communication: An experiment in co-evolving scientific and social knowledge

USGS Publications Warehouse

Graffy, E.A.; Booth, N.L.

2008-01-01

Dissemination of information to decision-makers and enhanced methods of public participation are often put forward as antidotes to a perceived disconnect between risk assessment and risk communication in the public domain. However, mechanisms that support both the provision of routine, timely and relevant technical knowledge to the public and meaningful opportunities for public participation in the evaluation and management of risk are few. We argue for the need to re-conceptualise the institutional context in which risk research and communication occur as one in which scientific knowledge and public understanding are co-evolutionary instead of independent or sequential. Here, we report on an experiment to promote coevolution of environmental risk assessment and risk communication through the instrumental use of a web-based platform that dynamically links expert and public discourses through common information sources, linked scenario evaluations, and opportunities for iterative dialogue. On the basis of technical feasibility, research value and public communication capacity, we conclude that there is potential for further refinement of the methodologies presented here.

Suicide is an important public health problem. Although there have been advances in our knowledge of suicide, gaps remain in knowledge about suicide risk factors and prevention. Here, we discuss research pathways that have the potential to rapidly advance knowledge in suicide risk assessment and reduction of suicide deaths over the next decade. We provide a concise overview of the methodologic approaches that have the capacity to rapidly increase knowledge and change practice, which have been successful in past work in psychiatry and other areas of medicine. We suggest three specific pathways to advance knowledge of suicide risk factors and prevention. First, analysis of large-scale epidemiologic surveys and administrative data sets can advance the understanding of suicide. Second, given the low base rate of suicide, there is a need for networks/consortia of investigators in the field of suicide prevention. Such consortia have the capacity to analyze existing epidemiologic data sets, create multi-site cohort studies of high-risk groups to increase knowledge of biological and other risk factors, and create a platform for multi-site clinical trials. Third, partnerships with policymakers and researchers would facilitate careful scientific evaluation of policies and programs aimed at reducing suicide. Suicide intervention policies are often multifaceted, expensive, and rarely evaluated. Using quasi-experimental methods or sophisticated analytic strategies such as propensity score-matching techniques, the impact of large-scale interventions on suicide can be evaluated. Furthermore, such partnerships between policymakers and researchers can lead to the design and support of prospective RCTs (e.g., cluster randomized trials, stepped wedge designs, waiting list designs) in high-risk groups (e.g., people with a history of suicide attempts, multi-axial comorbidity, and offspring of people who have died by suicide). These research pathways could lead to rapid knowledge uptake between communities and have the strong potential to reduce suicide. Copyright © 2014 American Journal of Preventive Medicine.

The aim of this hospital-based survey was to determine baseline stroke knowledge in Croatian population attending the outpatient services at the Department of Neurology. A multiple choice questionnaire was designed, divided into three sections: (i) demographic data, (ii) knowledge of stroke risk factors and stroke signs and (iii) actions the patients would undertake if confronted with risk of stroke and information resources regarding health. The analysis included 720 respondents (54.9% women). The respondents most frequently indicated stroke symptoms as following: speech disorder 82%, paresthesiae on one side of the body 71%, weakness of arm or leg 55%, unsteady gait 55%, malaise 53%, monocular loss of vision 44%. The risk factors most frequently identified were hypertension 64%, stress 61%, smoking 59%, elevated lipids 53%, obesity 52%, coagulation disorder 47%, alcoholism 45%, low-physical activity 42%, elderly age 39%, cardiac diseases 38%, weather changes 34%, drugs 33% and diabetes 32%. If confronted with stroke signs 37% of respondents would consult the general practitioner and 31% would call 911 or go to a neurologist. Amongst patients with a risk factor, only diabetics were aware that their risk factor might cause stroke (P < 0.001). Respondents with lowest education had the least knowledge regarding stroke signs (P < 0.01). The results of this study indicate that respondents showed a fair knowledge about stroke signs and risk factors for stroke. The results of our study will help to create and plan programmes for improvement of public health in Croatia.

In 2012, an estimated 35.3 million people lived with HIV, while approximately two million new HIV infections were reported. Community-based interventions (CBIs) for the prevention and control of HIV allow increased access and ease availability of medical care to population at risk, or already infected with, HIV. This paper evaluates the impact of CBIs on HIV knowledge, attitudes, and transmission. We included 39 studies on educational activities, counseling sessions, home visits, mentoring, women's groups, peer leadership, and street outreach activities in community settings that aimed to increase awareness on HIV/AIDS risk factors and ensure treatment adherence. Our review findings suggest that CBIs to increase HIV awareness and risk reduction are effective in improving knowledge, attitudes, and practice outcomes as evidenced by the increased knowledge scores for HIV/AIDS (SMD: 0.66, 95% CI: 0.25, 1.07), protected sexual encounters (RR: 1.19, 95% CI: 1.13, 1.25), condom use (SMD: 0.96, 95% CI: 0.03, 1.58), and decreased frequency of sexual intercourse (RR: 0.76, 95% CI: 0.61, 0.96). Analysis shows that CBIs did not have any significant impact on scores for self-efficacy and communication. We found very limited evidence on community-based management for HIV infected population and prevention of mother- to-child transmission (MTCT) for HIV-infected pregnant women. Qualitative synthesis suggests that establishment of community support at the onset of HIV prevention programs leads to community acceptance and engagement. School-based delivery of HIV prevention education and contraceptive distribution have also been advocated as potential strategies to target high-risk youth group. Future studies should focus on evaluating the effectiveness of community delivery platforms for prevention of MTCT, and various emerging models of care to improve morbidity and mortality outcomes.

The implementation of local wisdom in reducing natural disaster risk: a case study from West Sumatera

The purpose of this paper is to introduce some local wisdoms in West Sumatra and propose their challenges that modern values have degraded its knowledge. In a contemporary context, traditional stories (written and oral stories) still relevant to be used and internalized in disaster risk reduction. Traditional knowledge or local wisdom is a system of knowledge derived from long experienced process in the past, adopted and handed over to next generation through evolutionary process. Indigenous or traditional knowledge can be practiced in understanding the nature of natural disaster, to propose the best action in mitigation, to respond in emergency phase, and to suggest more option for recovery process based on previous experience. The paper based on four weeks field research in west Sumatra which is known with their natural hazards due to its geographical location. In the beginning, this paper discusses the nature of local wisdom and how it can be matched in disaster management, then continues to the specific case how the traditional stories in West Sumatera can be internalized and integrated with contemporary disaster risk reduction. This paper proves that local wisdom can be useful as an effective instrument to deal with natural disaster or natural hazard.

Workers' understanding of chemical risks: electroplating case study

Sadhra, S; Petts, J; McAlpine, S; Pattison, H; MacRae, S

2002-01-01

Background: There is limited research concerning how small companies in particular, respond to health and safety messages. Aims: To understand individuals' knowledge and beliefs about chemical risks and to compare these with those of experts. Methods: The use of chromic acid in particular, and also other chemicals associated with chrome plating were studied. All chromium plating firms were based in the West Midlands. The methodology involved initial face to face interviews (n = 21) with chromium platers, structured questionnaires (n = 84) to test the prevalence of beliefs identified in the interviews, an expert questionnaire, and a workshop to discuss findings. The responses of platers were compared with those of occupational health and safety experts. Results: Although chromium platers appeared to understand the short term adverse effects of the chemicals to which they are exposed, their understanding of long term, or chronic effects appeared to be incomplete. They had good knowledge of acute effects based primarily on experience. Platers were aware of the hazardous nature of the chemicals with which they work, but did not draw distinction between the terms "hazards" and "risks". They had difficulties articulating the effects of the chemicals and how exposure might occur; although it is inappropriate to equate this with lack of knowledge. A significant minority of platers displayed deficiencies in understanding key technical terms used in Safety Data Sheets. Conclusions: This study provides a method which can be used to gain some understanding of workers' knowledge and beliefs about risks that they are exposed to in the workplace. The study also identifies gaps between the platers' knowledge and beliefs and those of experts. New risk information needs to be designed which addresses the information needs of platers using language that they understand. PMID:12356930

The safety of diagnostic imaging during pregnancy is an important aspect for all clinicians. Pregnant women often do not receive proper dental care as the dentists are not aware of low diagnostic radiation doses involved in dental radiation. To assess awareness of radiation risks on pregnant women among dentists of Ghaziabad city. A total of 268 practicing dentists in Ghaziabad were selected for a questionnaire based cross-sectional study. Data consisted of 18 questions which assessed the knowledge, attitude and practice of dental professionals regarding radiation risks on pregnant women. The questionnaire was distributed and collected personally by the principal investigator. Data was analyzed by Mann Whitney U test and chi-square test. The level of significance was set at p ≤ 0.05. The results showed that the dentists who had attended continuing dental education program had increased level of knowledge regarding radiation effects among pregnant women as compared to the dentists who had not attended continuing dental education programs (p<0.05). Among them who had attended continuing dental education programs 93.3% were aware of the safe dose of radiation and 62% were aware of threshold radiation doses of pregnancy termination. On the contrary there was no significant difference in the knowledge, attitude and practice scores regarding radiation risks on pregnant women based on their academic qualification (p≥0.05). The level of knowledge among dentists was found to be satisfactory, this outcome shows that continuing dental education regarding radiation protection principles and its risks on pregnant women is required to ensure maximum safety both for clinician as well as pregnant women.

Evolution of Public Participation in the Assessment and Management of Environmental Health Risks: A Brief History of Developments in the United States

Significance for public health Risk-based decision making is a core feature of government actions aimed at protecting public health from the adverse effects of environmental hazards. In the past, it has often been an expert-driven, mostly obscure process used by federal agencies to justify and defend regulatory decisions made outside the public arena. But the nature of decision making has changed as it has become apparent that environmental health problems are more complicated, controversial, and costly to solve than originally thought. Meaningful public engagement is now an inherent component of all phases of the risk assessment – risk management paradigm because it promotes stakeholder buy in, taps into unique stakeholder knowledge, and promotes the concept of environmental democracy. In the United States, the risk assessment – risk management paradigm that underpins federal decisions about environmental health risks was first established in 1983. In the beginning, the importance of public participation was not explicitly recognized within the paradigm. Over time, however, it has become evident that not only must risk-based decisions be founded on the best available scientific knowledge and understanding, but also that they must take account of the knowledge, values, and preferences of interested and affected parties, including community members, business people, and environmental advocates. This article examines the gradually expanding role of public participation in risk-based decision making in the United States, and traces its evolution from a peripheral issue labeled as an external pressure to an integral element of the 21st century risk assessment – risk management paradigm. Today, and into the foreseeable future, public participation and stakeholder involvement are intrinsic features of the emerging American regulatory landscape, which emphasizes collaborative approaches for achieving cooperative and cost-effective solutions to complicated and often controversial environmental health problems.

2001-09-01

Endotracheal suctioning is a frequently performed procedure that has many associated risks and complications. It is imperative that nurses are aware of these risks and are able to practise according to current research recommendations. This study was designed to examine to what extent intensive care nurses' knowledge and practice of endotracheal suctioning is based on research evidence, to investigate the relationships between knowledge and practice, and to evaluate the effectiveness of a research-based teaching programme. This quasi-experimental study was a randomized, controlled, single-blinded comparison of two research-based teaching programmes, with 16 intensive care nurses, using non-participant observation and a self-report questionnaire. Initial baseline data revealed a low level of knowledge for many participants, which was also reflected in practice, as suctioning was performed against many of the research recommendations. Following teaching, significant improvements were seen in both knowledge and practice. Four weeks later these differences were generally sustained, and provide evidence of the effectiveness of the educational intervention. The study raised concern about all aspects of endotracheal suctioning and highlighted the need for changes in nursing practice, with clinical guidelines and focused practice-based education.

The current study examines associations between marital conflict and negative parenting behaviors among fathers and mothers, and the extent to which internal working models (IWMs) of attachment relationships may serve as sources of risk or resilience during family interactions. The sample consisted of 115 families (mothers, fathers, and their 6-month-old infants) who participated in a controlled experiment. Couples were randomly assigned to engage in either a conflict or positive marital discussion, followed by parent-infant freeplay sessions and assessment of parental IWMs of attachment (i.e., secure base script knowledge). While no differences in parenting behaviors emerged between the conflict and positive groups, findings revealed that couple withdrawal during the marital discussion was related to more intrusive and emotionally disengaged parenting for mothers and fathers. Interestingly, secure base script knowledge was inversely related to intrusion and emotional disengagement for fathers, but not for mothers. Furthermore, only among fathers did secure base script knowledge serve to significantly buffer the impact of marital disengagement on negative parenting (emotional disengagement). Findings are discussed using a family systems framework and expand our understanding of families, and family members, at risk. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

This paper examines decision-making around sexual behavior among reservation-based American Indian youth. Focus group discussions were conducted with youth ages 13-19 years old. Through these discussions, we explored youth's knowledge, attitudes and behaviors related to sexual risk taking through the lens of the protection motivation theory to inform the adaptation of an evidence-based HIV prevention intervention. Findings suggest that condom use self-efficacy and HIV prevention knowledge is low, vulnerability to sexually transmitted infections is lacking and alcohol plays a significant role in sexual risk taking in this population. In addition, parental monitoring and peer influence may contribute to or protect against sexual risk taking. Results suggest that future HIV prevention interventions should be delivered to gender-specific peer groups, include a parental component, teach sexual health education and communication skills, integrate substance-use prevention, and work to remove stigma around obtaining and using condoms.

Harnessing the Risk-Related Data Supply Chain: An Information Architecture Approach to Enriching Human System Research and Operations Knowledge

NASA's Human Research Program (HRP) and Space Life Sciences Directorate (SLSD), not unlike many NASA organizations today, struggle with the inherent inefficiencies caused by dependencies on heterogeneous data systems and silos of data and information spread across decentralized discipline domains. The capture of operational and research-based data/information (both in-flight and ground-based) in disparate IT systems impedes the extent to which that data/information can be efficiently and securely shared, analyzed, and enriched into knowledge that directly and more rapidly supports HRP's research-focused human system risk mitigation efforts and SLSD s operationally oriented risk management efforts. As a result, an integrated effort is underway to more fully understand and document how specific sets of risk-related data/information are generated and used and in what IT systems that data/information currently resides. By mapping the risk-related data flow from raw data to useable information and knowledge (think of it as the data supply chain), HRP and SLSD are building an information architecture plan to leverage their existing, shared IT infrastructure. In addition, it is important to create a centralized structured tool to represent risks including attributes such as likelihood, consequence, contributing factors, and the evidence supporting the information in all these fields. Representing the risks in this way enables reasoning about the risks, e.g. revisiting a risk assessment when a mitigation strategy is unavailable, updating a risk assessment when new information becomes available, etc. Such a system also provides a concise way to communicate the risks both within the organization as well as with collaborators. Understanding and, hence, harnessing the human system risk-related data supply chain enhances both organizations' abilities to securely collect, integrate, and share data assets that improve human system research and operations.

Public awareness of stroke risks and warning signs remains poor. The National Stroke Foundation (NSF) in Australia has been undertaking a StrokeSafe Ambassador Education program to raise awareness of stroke. The format includes presentations by volunteers trained to be 'ambassadors' to spread standard information about stroke to the public. Our aim was to determine the change in knowledge of participants who attended presentations. Participants completed questionnaires before immediately after presentations, and at 3months following the presentation. Information was collected on knowledge of risk factors and signs of stroke. McNemar's test was used to compare paired-responses over time. A p value of <0.05 was considered significant. Between March and April 2014, 591 participants attended 185 presentations and 591 (100%) completed them before and immediately after presentation questionnaires: 68% were female and 75% were aged 65years or more. 258 consented for further follow-up with 192 completing follow-up. Comparing immediately after with before presentation showed significantly improved knowledge for all 10 stroke risk factors and all signs of stroke. Significantly improved knowledge for 7/10 risk factors and 1/3 signs of stroke was found when comparing follow-up and immediately after presentation results. Knowledge of 5/10 risk factors and 2/3 signs of stroke improved when comparing follow-up and before presentation. This study describes a novel approach to support the use of trained volunteers to provide a community-based, standardised education program for stroke. This program shows that community presentations can improve immediate and short-term knowledge of signs and risk factors for stroke. Copyright © 2016. Published by Elsevier Inc.

Pressure area care: an exploration of Greek nurses' knowledge and practice.

Despite a plethora of information on the prevention of pressure sores, they remain a significant problem in both hospital and community settings. The need to reduce the incidence of pressure sores has been well documented; unfortunately there is little evidence to suggest improvement. The reasons for this lack of improvement have been explored, but the picture remains unclear. While some studies have suggested that nurses have the appropriate knowledge to prevent pressure sores developing (but do not use their knowledge), others suggest that nurses' knowledge of preventive strategies is deficient. In Greece, similarly to the United Kingdom (UK), the incidence of pressure sores is high. There is currently no evidence on Greek nurses' knowledge and practice and therefore no baseline on which to build, in terms of improving practice. The purpose of this study was to explore Greek nurses' knowledge of 'risk factors', 'areas at risk' and 'recommended preventive strategies' in relation to pressure area care. In addition, information was sought on nurses' 'current preventive practice' and any barriers to 'good practice'. The study was exploratory and descriptive, adopting a cross-sectional survey approach. The sample was drawn from the population of nurses working in a military hospital near Athens. The data were collected over a 4-week period in June 2000, using a self-completed questionnaire. Although the knowledge-base of many of the nurses was good in relation to 'risk factors' and 'areas at risk', a significant proportion were unaware that methods such as 'massage' and 'donuts' are no longer recommended. This lack of knowledge influenced practice with these methods commonly being used. In relation to barriers to good practice, a significant proportion of nurses reported that they could not access, read or understand research findings. This has obvious implications for the implementation of evidence-based practice. The results of this study suggest that the knowledge and practice of participants could be improved. It is of particular concern that methods known to be detrimental were in common use. Finally, there is a need to improve the research skills of Greek nurses in order to provide them with the appropriate knowledge to use research findings.

We adopted a comparative approach to evaluate and extend a generic methodology to analyze the different sets of beliefs held about chemical hazards in the workplace. Our study mapped existing knowledge structures about the risks associated with the use of perchloroethylene and rosin-based solder flux in differing workplaces. "Influence diagrams" were used to represent beliefs held by chemical experts; "user models" were developed from data elicited from open-ended interviews with the workplace users of the chemicals. The juxtaposition of expert and user understandings of chemical risks enabled us to identify knowledge gaps and misunderstandings and to reinforce appropriate sets of safety beliefs and behavior relevant to chemical risk communications. By designing safety information to be more relevant to the workplace context of users, we believe that employers and employees may gain improved knowledge about chemical hazards in the workplace, such that better chemical risk management, self-protection, and informed decision making develop over time.

Achieving the policy and practice shifts needed to secure ecosystem services is hampered by the inherent complexities of ecosystem services and their management. Methods for the participatory production and exchange of knowledge offer an avenue to navigate this complexity together with the beneficiaries and managers of ecosystem services. We develop and apply a knowledge coproduction approach based on social-ecological systems research and assess its utility in generating shared knowledge and action for ecosystem services. The approach was piloted in South Africa across four case studies aimed at reducing the risk of disasters associated with floods, wildfires, storm waves, and droughts. Different configurations of stakeholders (knowledge brokers, assessment teams, implementers, and bridging agents) were involved in collaboratively designing each study, generating and exchanging knowledge, and planning for implementation. The approach proved useful in the development of shared knowledge on the sizable contribution of ecosystem services to disaster risk reduction. This knowledge was used by stakeholders to design and implement several actions to enhance ecosystem services, including new investments in ecosystem restoration, institutional changes in the private and public sector, and innovative partnerships of science, practice, and policy. By bringing together multiple disciplines, sectors, and stakeholders to jointly produce the knowledge needed to understand and manage a complex system, knowledge coproduction approaches offer an effective avenue for the improved integration of ecosystem services into decision making.

Objectives This study aimed to determine the effect of a stroke education programme on elementary school students and their parental guardians in a rural area in Japan that has high stroke mortality. Design School class based intervention study. Setting Eleven public elementary schools in Tochigi Prefecture, Japan. Participants 268 students aged 11–12 years and 267 parental guardians. Interventions Students received lessons about stroke featuring animated cartoons and were instructed to communicate their knowledge about stroke to their parental guardians using material (comic books) distributed in the lessons. Stroke knowledge (symptoms, risk factors and attitude towards stroke) and behavioural change for risk factors were assessed at baseline, immediately after the programme and at 3 months. We also evaluated behavioural change for risk factors among parental guardians. Results The percentage of students with all correct answers for stroke symptoms, risk factors and the recommended response to stroke was significantly increased at 3 months P<0.001). We observed a significant increase in the percentage of guardians who chose all correct symptoms (P<0.001: 61.0% vs 85.4%) and risk factors (P<0.001: 41.2% vs 59.9%) at 3 months compared with baseline. The percentage of parental guardians with a high behavioural response to improving risk factors was significantly increased at 3 months compared with baseline (P<0.001). Conclusions In a rural population with high stroke mortality, stroke education can improve knowledge about stroke in elementary school students and their parental guardians.

This study was conducted to examine effects of a small group-based cardiocerebrovascular disease (CVD) prevention education program on knowledge, stage of change and health behavior among male bus drivers with CVD risk factors. A non-equivalent control group pretest-posttest design was used. Participants were 68 male bus drivers recruited from two urban bus companies. Participants from the two groups were selected by matching age, education and risk factors. Experimental group (n=34) received a small group-based CVD prevention education program 8 times over 6 weeks and 3 times through telephone interviews at 2-week intervals. Data were collected between December, 2010 and March, 2011, and were analyzed using chi-square test, t-test, and repeated measure analysis of variance with SPSS/Win18.0. Experimental group showed significantly higher scores in CVD prevention knowledge (p<.001) and health behavior (p<.001) at 6 and 12 weeks after intervention. Participants in pre-contemplation and contemplation stages made progress to contemplation and action. This was significantly better at 6 and 12 weeks after intervention (p<.001). Results suggest that small group-based education programs for CVD prevention are effective in increasing knowledge, stage of change, and health behavior to prevent CVD among male bus drivers with CVD risk.

Preventing Suicide: A Neglected Social Work Research Agenda

2009-01-01

Summary Social workers encounter suicidal clients; however, little is known about social work’s empirical knowledge base for suicide assessment and treatment. In the first comprehensive study of social work’s contribution to the suicide literature, the authors conducted systematic electronic and manual searches for suicide research published in peer-reviewed journals by social work investigators for the period 1980–2006, with the purpose of ascertaining the state of clinical knowledge related to suicide risk factors and effective treatments. These findings reveal that despite recent increases to the study of suicide by social work researchers, they have contributed limited evidenced-based knowledge in the last twenty-six years on the treatment or prevention of suicide or suicide-related behaviours. The article outlines the risk factors for suicide and discusses the implications for clinical social work practice and research. PMID:19924271

Patients' perception of risk: informed choice in prenatal testing for foetal aneuploidy.

Each of us perceives risk differently, and so do our patients. This perception of risk gets even more complex when multiple individuals and interactions are involved: the doctor, the patient-pregnant mother, the spouse-father and the foetus-unborn child. In this review, we address the relationship between different levels of information gathering, from clinical data to experiential knowledge - data, information, knowledge, perception, attitude, wisdom - and how these would impact the perception of risk and informed consent. We discuss how patients might interpret the risks of the same event differently based upon past experiences, and suggest how risk data could be presented more meaningfully for patients and family to assimilate for informed decision making. Finally, we demonstrate how patients' expectations and risk management can impact scientific research and clinical progress by way of the most topical subject of risk screening in pregnancy - non-invasive prenatal testing using cell-free DNA in maternal plasma.

Occupational exposure to infection is an important public health concern. Such accidents are associated with a few, but pose significant risk to worker's health, family and the community. 1) To assess the knowledge and attitude of waste handlers regarding healthcare waste management in tertiary care hospital of Mangalore. 2) To assess the occupational risk of exposure to infection in their work setting. A cross-sectional study was conducted among healthcare waste handlers (involved in collection, storage and safe disposal) in a tertiary care hospital of Mangalore, India. A semi-structured and pre-tested proforma was used to assess respondents' knowledge and percentage score was calculated based on a scoring system. Chi square and independent sample t tests were applied to judge the association of study variables with knowledge and occupational risk of infection. A total of 43 healthcare waste handlers participated in the study and all were females. Almost half of them had poor knowledge (< 50% score) about healthcare waste management. As much as 41.8% of them had exposure to healthcare waste and 'needle stick injury' was the most common type. Age, literacy and experience did not significantly (p>0.05) influence the knowledge and occupational risk of infection. Respondents' knowledge regarding healthcare waste management was unsatisfactory. They were at high risk of occupational exposure to infection. It emphasizes the need of refresher training and reinforcement of personal protection measures in their work setting. © Journal of the Association of Physicians of India 2011.

MO-G-304-01: FEATURED PRESENTATION: Expanding the Knowledge Base for Data-Driven Treatment Planning: Incorporating Patient Outcome Models

Robertson, SP; Quon, H; Cheng, Z

2015-06-15

Purpose: To extend the capabilities of knowledge-based treatment planning beyond simple dose queries by incorporating validated patient outcome models. Methods: From an analytic, relational database of 684 head and neck cancer patients, 372 patients were identified having dose data for both left and right parotid glands as well as baseline and follow-up xerostomia assessments. For each existing patient, knowledge-based treatment planning was simulated for by querying the dose-volume histograms and geometric shape relationships (overlap volume histograms) for all other patients. Dose predictions were captured at normalized volume thresholds (NVT) of 0%, 10%, 20, 30%, 40%, 50%, and 85% and weremore » compared with the actual achieved doses using the Wilcoxon signed-rank test. Next, a logistic regression model was used to predict the maximum severity of xerostomia up to three months following radiotherapy. Baseline xerostomia scores were subtracted from follow-up assessments and were also included in the model. The relative risks from predicted doses and actual doses were computed and compared. Results: The predicted doses for both parotid glands were significantly less than the achieved doses (p < 0.0001), with differences ranging from 830 cGy ± 1270 cGy (0% NVT) to 1673 cGy ± 1197 cGy (30% NVT). The modelled risk of xerostomia ranged from 54% to 64% for achieved doses and from 33% to 51% for the dose predictions. Relative risks varied from 1.24 to 1.87, with maximum relative risk occurring at 85% NVT. Conclusions: Data-driven generation of treatment planning objectives without consideration of the underlying normal tissue complication probability may Result in inferior plans, even if quality metrics indicate otherwise. Inclusion of complication models in knowledge-based treatment planning is necessary in order to close the feedback loop between radiotherapy treatments and patient outcomes. Future work includes advancing and validating complication models in the context of knowledge-based treatment planning. This work is supported by Philips Radiation Oncology Systems.« less

Using agent-based modeling to study multiple risk factors and multiple health outcomes at multiple levels.

PubMed

Yang, Yong

2017-11-01

Most health studies focus on one health outcome and examine the influence of one or multiple risk factors. However, in reality, various pathways, interactions, and associations exist not only between risk factors and health outcomes but also among the risk factors and among health outcomes. The advance of system science methods, Big Data, and accumulated knowledge allows us to examine how multiple risk factors influence multiple health outcomes at multiple levels (termed a 3M study). Using the study of neighborhood environment and health as an example, I elaborate on the significance of 3M studies. 3M studies may lead to a significantly deeper understanding of the dynamic interactions among risk factors and outcomes and could help us design better interventions that may be of particular relevance for upstream interventions. Agent-based modeling (ABM) is a promising method in the 3M study, although its potentials are far from being fully explored. Future challenges include the gap of epidemiologic knowledge and evidence, lack of empirical data sources, and the technical challenges of ABM. © 2017 New York Academy of Sciences.

Invasive species risk maps provide broad guidance on where to allocate resources for pest monitoring and regulation, but they often present individual risk components (such as climatic suitability, host abundance, or introduction potential) as independent entities. These independent risk components are integrated using various multicriteria analysis techniques that typically require prior knowledge of the risk components' importance. Such information is often nonexistent for many invasive pests. This study proposes a new approach for building integrated risk maps using the principle of a multiattribute efficient frontier and analyzing the partial order of elements of a risk map as distributed in multidimensional criteria space. The integrated risks are estimated as subsequent multiattribute frontiers in dimensions of individual risk criteria. We demonstrate the approach with the example of Agrilus biguttatus Fabricius, a high-risk pest that may threaten North American oak forests in the near future. Drawing on U.S. and Canadian data, we compare the performance of the multiattribute ranking against a multicriteria linear weighted averaging technique in the presence of uncertainties, using the concept of robustness from info-gap decision theory. The results show major geographic hotspots where the consideration of tradeoffs between multiple risk components changes integrated risk rankings. Both methods delineate similar geographical regions of high and low risks. Overall, aggregation based on a delineation of multiattribute efficient frontiers can be a useful tool to prioritize risks for anticipated invasive pests, which usually have an extremely poor prior knowledge base.

Deriving horse oocytes in the USA is hampered by the lack of abattoirs processing horse carcasses which could provide abundant quantities of ovaries from slaughtered mares. Therefore, several cloning industries in the USA are attempting to import cloned horse embryos from Canada. Like any agricultural commodity, cloned embryos pose a risk of introduction of exotic animal diseases into the importing country. Under such circumstances, risk assessment could provide an objective, transparent, and internationally accepted means for evaluating the risk. This quantitative risk assessment (QRA) was initiated to determine the risk of introduction of Equine infectious anemia virus (EIAV) into the USA via cloned horse embryos imported from Canada. In assessing the risk, a structured knowledge base regarding cloning in relation to Equine infectious anemia (EIA) was first developed. Based on the knowledge base, a scenario tree was developed to determine conditions (with mathematical probabilities) that could lead to the introduction and maintenance of EIAV along the cloning pathway. Parameters for the occurrence of the event at each node were estimated using published literature. Using @Risk software and setting Monte Carlo simulation at 50,000 iterations, the probability of importing an EIAV-infected cloned horse embryo was 1.8 × 10(-9) (R = 1.5 × 10(-12) to 2.9 × 10(-8)). Taking into account the current protocol for equine cloning and assuming the yield of 5 to 30 clones per year, the possible number of EIAV-infected cloned horse embryos ranged from 2.0 × 10(-10) to 9.1 × 10(-5) (Mean = 1.4×10(-6)) per year. Consequently, it would take up to 1.5 × 10(7) (R = 1.6 × 10(4) to 5.1 × 10(10)) years for EIAV to be introduced into the USA. Based on the knowledge base and our critical pathway analysis, the biological plausibility of introducing EIAV into USA via cloned horse embryos imported from Canada is extremely low.

It is hypothesised that individuals with knowledge of their genetic risk are more likely to make health-promoting dietary and lifestyle changes. The present study aims to test this hypothesis using data from the Food4Me study. This was a 6-month Internet-based randomised controlled trial conducted across seven centres in Europe where individuals received either general healthy eating advice or varying levels of personalised nutrition advice. Participants who received genotype-based personalised advice were informed whether they had the risk (CT/TT) ( n  = 178) or non-risk (CC) ( n  = 141) alleles of the methylenetetrahydrofolate reductase ( MTHFR ) gene in relation to cardiovascular health and the importance of a sufficient intake of folate. General linear model analysis was used to assess changes in folate intake between the MTHFR risk, MTHFR non-risk and control groups from baseline to month 6 of the intervention. There were no differences between the groups for age, gender or BMI. However, there was a significant difference in country distribution between the groups ( p  = 0.010). Baseline folate intakes were 412 ± 172, 391 ± 190 and 410 ± 186 μg per 10 MJ for the risk, non-risk and control groups, respectively. There were no significant differences between the three groups in terms of changes in folate intakes from baseline to month 6. Similarly, there were no changes in reported intake of food groups high in folate. These results suggest that knowledge of MTHFR 677C → T genotype did not improve folate intake in participants with the risk variant compared with those with the non-risk variant.

This study set out to facilitate the development of evidence-based practice in the assessment of pressure damage risk to patients within a large acute hospital. The importance of nursing practice being based on the best available evidence is emphasized in recent health policy. Meeting this objective is not easy as both individual and organizational factors create barriers to the implementation of research findings and the achievement of change. The study was based on an action research model. It comprised three stages: a review of the research evidence; a survey of qualified nurses' knowledge of risk assessment of pressure damage and an audit of record keeping, and a multifaceted approach to achieving change in which researchers, managers, practitioners and clinical nurse specialists worked together collaboratively. The findings from the survey and audit indicated a shortfall in nurses' knowledge of risk assessment of pressure damage and in their record keeping. The researchers, with the help of the clinical nurse specialist, built upon these findings by assisting practitioners and managers to take ownership of the need to base practice on the appropriate evidence. Achieving evidence-based practice is a complex undertaking that requires the development of an evaluative culture and a commitment by practitioners and managers to change practice. Researchers can play a valuable role in facilitating this process.

This article aimed to determine sexual behaviors among female and male adolescents in northern Italy. An anonymous self-administered questionnaire evaluating sexual attitudes was distributed in middle and high schools in northern Italy. Adolescents between 13 and 19 years of age were asked to participate at the survey. The study group included 664 participants. Overall, 164 (25%) adolescents had had at least one sexual intercourse. Among adolescents who have had sexual intercourse, 90 (55%) use condoms, 25 (15%) use hormonal contraception, and 49 (30%) do not use any contraception method. A total of 559 adolescents (84%) participated in school-based sexual education programs. This group had better knowledge on sexually transmitted diseases and contraception methods in comparison with adolescents who have never participated in such educational programs (p <.05), and no difference in high-risk sexual behaviors was observed (p = 1.0). School-based sexual education programs improve knowledge of sexual transmitted diseases and contraception methods. However, this knowledge does not correlate to high-risk sexual behaviors reduction.

Non-medical, community-based workers play a critical role in supporting people living with (or at risk of acquiring) HIV along the care continuum. The biomedical nature of promising advances in HIV prevention, such as pre-exposure prophylaxis and treatment-as-prevention, requires frontline workers to be knowledgeable about HIV science and treatment. This study was developed to: measure knowledge of HIV science and treatment within the HIV non-medical workforce, evaluate workers' familiarity with and attitudes toward recent biomedical interventions, and identify factors that may affect HIV knowledge and attitudes. A 62-question, web-based survey was completed in English or Spanish between 2012 and 2014 by 3663 US-based employees, contractors, and volunteers working in AIDS service organizations, state/local health departments, and other community-based organizations in a non-medical capacity. Survey items captured the following: respondent demographics, HIV science and treatment knowledge, and familiarity with and attitudes toward biomedical interventions. An average of 61% of HIV knowledge questions were answered correctly. Higher knowledge scores were associated with higher education levels, work at organizations that serve people living with HIV/AIDS or who are at a high risk of acquiring HIV, and longer tenure in the field. Lower knowledge scores were associated with non-Hispanic Black or Black race/ethnicity and taking the survey in Spanish. Similarly, subgroup analyses showed that respondents who were non-Hispanic Black or Hispanic (versus non-Hispanic white), as well as those located in the South (versus other regions) scored significantly lower. These subpopulations were also less familiar with and had less positive attitudes toward newer biomedical prevention interventions. Respondents who took the survey in Spanish (versus English) had lower knowledge scores and higher familiarity with, but generally less positive attitudes toward, biomedical interventions. In summary, low knowledge scores suggest the need for additional capacity-building efforts and training for non-medical HIV workers, particularly those who provide services in the communities most affected by HIV.

Problem Formulation in Knowledge Discovery via Data Analytics (KDDA) for Environmental Risk Management

2016-01-01

With the growing popularity of data analytics and data science in the field of environmental risk management, a formalized Knowledge Discovery via Data Analytics (KDDA) process that incorporates all applicable analytical techniques for a specific environmental risk management problem is essential. In this emerging field, there is limited research dealing with the use of decision support to elicit environmental risk management (ERM) objectives and identify analytical goals from ERM decision makers. In this paper, we address problem formulation in the ERM understanding phase of the KDDA process. We build a DM3 ontology to capture ERM objectives and to inference analytical goals and associated analytical techniques. A framework to assist decision making in the problem formulation process is developed. It is shown how the ontology-based knowledge system can provide structured guidance to retrieve relevant knowledge during problem formulation. The importance of not only operationalizing the KDDA approach in a real-world environment but also evaluating the effectiveness of the proposed procedure is emphasized. We demonstrate how ontology inferencing may be used to discover analytical goals and techniques by conceptualizing Hazardous Air Pollutants (HAPs) exposure shifts based on a multilevel analysis of the level of urbanization (and related economic activity) and the degree of Socio-Economic Deprivation (SED) at the local neighborhood level. The HAPs case highlights not only the role of complexity in problem formulation but also the need for integrating data from multiple sources and the importance of employing appropriate KDDA modeling techniques. Challenges and opportunities for KDDA are summarized with an emphasis on environmental risk management and HAPs. PMID:27983713

Stroke and myocardial infarction (MI) represent 2 of the leading causes of death in the United States. The early recognition of risk factors and event symptoms allows for the mitigation of disability or death. We sought to compare subject knowledge of stroke and MI, assess subject risk for cardiovascular disease, and determine if an association exists between knowledge and risk. In this cross-sectional survey, adult, non-health care professionals were presented with a written knowledge test and risk assessment tool. Subjects were classified into 3 categories of cardiovascular risk. Associations were then calculated between knowledge, risk, and population demographics. Of 500 subjects approached, 364 were enrolled. The subjects were mostly white, middle-aged, and high school educated. Gender and income were evenly distributed. Forty-eight (14%) subjects were identified as ideal risk, 130 (38%) as low risk, and 168 (49%) as moderate/high risk. MI and stroke knowledge scores decreased as cardiovascular risk increased (85%, 79%, and 73% for ideal, low, and moderate/high risk groups, respectively; P < .001). In addition, regardless of risk category, stroke knowledge scores were always lower than heart attack knowledge scores. Knowledge about stroke and MI was modest, with knowledge of MI exceeding that of stroke at every level of risk. Subjects with higher risk were less knowledgeable about the stroke signs, symptoms, and risk factors than those of MI. Copyright © 2013 National Stroke Association. Published by Elsevier Inc.

Using XML and XSLT for flexible elicitation of mental-health risk knowledge.

PubMed

Buckingham, C D; Ahmed, A; Adams, A E

2007-03-01

Current tools for assessing risks associated with mental-health problems require assessors to make high-level judgements based on clinical experience. This paper describes how new technologies can enhance qualitative research methods to identify lower-level cues underlying these judgements, which can be collected by people without a specialist mental-health background. Content analysis of interviews with 46 multidisciplinary mental-health experts exposed the cues and their interrelationships, which were represented by a mind map using software that stores maps as XML. All 46 mind maps were integrated into a single XML knowledge structure and analysed by a Lisp program to generate quantitative information about the numbers of experts associated with each part of it. The knowledge was refined by the experts, using software developed in Flash to record their collective views within the XML itself. These views specified how the XML should be transformed by XSLT, a technology for rendering XML, which resulted in a validated hierarchical knowledge structure associating patient cues with risks. Changing knowledge elicitation requirements were accommodated by flexible transformations of XML data using XSLT, which also facilitated generation of multiple data-gathering tools suiting different assessment circumstances and levels of mental-health knowledge.

Personalized risk communication for personalized risk assessment: Real world assessment of knowledge and motivation for six mortality risk measures from an online life expectancy calculator.

2018-01-01

In the clinical setting, previous studies have shown personalized risk assessment and communication improves risk perception and motivation. We evaluated an online health calculator that estimated and presented six different measures of life expectancy/mortality based on a person's sociodemographic and health behavior profile. Immediately after receiving calculator results, participants were invited to complete an online survey that asked how informative and motivating they found each risk measure, whether they would share their results and whether the calculator provided information they need to make lifestyle changes. Over 80% of the 317 survey respondents found at least one of six healthy living measures highly informative and motivating, but there was moderate heterogeneity regarding which measures respondents found most informative and motivating. Overall, health age was most informative and life expectancy most motivating. Approximately 40% of respondents would share the results with their clinician (44%) or social networks (38%), although the information they would share was often different from what they found informative or motivational. Online personalized risk assessment allows for a more personalized communication compared to historic paper-based risk assessment to maximize knowledge and motivation, and people should be provided a range of risk communication measures that reflect different risk perspectives.

The slings and arrows of communication on nanotechnology

Zimmer, René; Vierboom, Carl; Härlen, Ingo; Hertel, Rolf; Böl, Gaby-Fleur

2009-01-01

According to numerous surveys the perceived risk of nanotechnology is low and most people feel that the benefits outweigh the risks. This article provides greater insight into risk perception and concludes that the positive attitude to nanotechnology is based not on knowledge but on hope and fascination. The perceived risk is low because of a lack of vivid and frightening images of possible hazards. If news flashes were to link nanotechnology to concrete hazards or actual harm to people, attitudes might suddenly change. Risk communication faces the problem of dealing with a public at large that has little or no knowledge about the technology. As it takes time and extensive additional research to develop appropriate communication strategies and disseminate them to the relevant institutions, this exercise should be started immediately.

The knowledge of warning symptoms and risk factors for stroke has not been studied among patients with stroke in developing countries. We aimed to assess the knowledge of stroke among patients with stroke and their relatives. Prospective tertiary referral hospital-based study in Northwest India. Trained nurses and medical interns interviewed patients with stroke and transient ischemic attack and their relatives about their knowledge of stroke symptoms and risk factors. Univariable and multivariable logistic regression were used. Of the 147 subjects interviewed, 102 (69%) were patients and 45 (31%) were relatives. There were 99 (67%) men and 48 (33%) women and the mean age was 59.7+/-14.1 years. Sixty-two percent of respondents recognized paralysis of one side as a warning symptom and 54% recognized hypertension as a risk factor for stroke. In the multivariable logistic regression analysis, higher education was associated with the knowledge of correct organ involvement in stroke (OR 2.6, CI 1.1- 6.1, P =0.02), whereas younger age (OR 2.7, CI 1.1-7.0, P =0.04) and higher education (OR 4.1, CI 1.5-10.9, P =0.005) correlated with a better knowledge regarding warning symptoms of stroke. In this study cohort, in general, there is lack of awareness of major warning symptoms, risk factors, organ involvement and self-recognition of stroke. However younger age and education status were associated with better knowledge. There is an urgent need for awareness programs about stroke in this study cohort.

Objectives This project aimed to gain better understandings of northern Indigenous risk perception related to food safety and to identify the role that Indigenous knowledge (IK) plays in risk management processes to support more effective and culturally relevant benefit-risk (B-R) management strategies. Study design The project used an exploratory qualitative case study design to investigate the role and place of IK in the management of environmental contaminants exposure via consumption of traditional foods in Yukon First Nations (YFNs). Methods Forty-one semi-directive interviews with Traditional Food Knowledge Holders and Health and Environment Decision-makers were conducted. A review and analysis of organizational documents related to past risk management events for the issue was conducted. Thematic content analysis was used to analyze transcripts and documents for key themes related to the research question. Results There was a recognized need by all participants for better collaboration between scientists and YFN communities. YFNs have been involved in identifying and defining community concerns about past risk issues, setting a local context, and participating in communications strategies. Interviewees stressed the need to commit adequate time for building relationships, physically being in the community, and facilitating open communication. Conducting community-based projects was identified as critical for collaboration and for cooperative learning and management of these issues. Conclusions The perception of “effective” benefit-risk management is significantly influenced by the efforts made to include local communities in the process. A set of common guiding principles within a process that brings together people and knowledge systems may provide a more effective way forward in cross-cultural, multiple knowledge system contexts for complex benefit-risk issues than a prescriptive rigid framework.

Effectiveness studies of preschool social-emotional programs are needed in low-income, diverse populations to help promote the well-being of at-risk children. Following an initial program efficacy study 2 years prior, 248 culturally diverse Head Start preschool children participated in the current effectiveness trial and received either the Emotion-Based Prevention Program (EBP) or the I Can Problem Solve (ICPS) intervention. Pre- and postdata collection included direct child assessment, teacher report, parent interview, and independent observations. Teachers implementing the EBP intervention demonstrated good and consistent fidelity to the program. Overall, children in EBP classrooms gained more emotion knowledge and displayed greater decreases in negative emotion expressions and internalizing behaviors across the implementation period as compared to children in ICPS classrooms. In addition, cumulative risk, parental depressive symptoms, and classroom climate significantly moderated treatment effects. For children experiencing more stress or less support, EBP produced more successful outcomes than did ICPS. These results provide evidence of EBP sustainability and program effectiveness, as did previous findings that demonstrated EBP improvements in emotion knowledge, regulation skills, and behavior problems replicated under unsupervised program conditions.

The healing and preventive forces related to individuals' health resources and self-assessed knowledge have hitherto been underestimated in medicine. In this article, we draw attention to ethical and epistemological challenges in relation to values, communication, knowledge, and autonomy that are embedded in the prevailing risk-oriented epidemiology. We have developed a theoretical model for a patient-centered, salutogenetic approach with the aim of a better balance between health resources and risk factors. We briefly present results of dialogues in the general practice consultation based on key questions about self-assessed health resources. We discuss pitfalls related to causality, group-based probabilities, medicalization, and informed consent, focusing on the clinical encounter with the individual patient. By introducing a salutogenetic perspective, we hope to shift attention towards the patient's resources and strengths. Communication can mediate oppression as well as empowerment.

Health risk assessments are becoming more popular as a tool to conveniently and effectively reach community-dwelling adults who may be at risk for serious chronic conditions such as coronary heart disease (CHD). The use of such instruments to improve adults' risk factor awareness and concordance with clinically measured risk factor values could be an opportunity to advance public health knowledge and build effective interventions. The objective of this study was to determine if an Internet-based health risk assessment can highlight important aspects of agreement between respondents' self-reported and clinically measured CHD risk factors for community-dwelling adults who may be at risk for CHD. Data from an Internet-based cardiovascular health risk assessment (Heart Aware) administered to community-dwelling adults at 127 clinical sites were analyzed. Respondents were recruited through individual hospital marketing campaigns, such as media advertising and print media, found throughout inpatient and outpatient facilities. CHD risk factors from the Framingham Heart Study were examined. Weighted kappa statistics were calculated to measure interrater agreement between respondents' self-reported and clinically measured CHD risk factors. Weighted kappa statistics were then calculated for each sample by strata of overall 10-year CHD risk. Three samples were drawn based on strategies for treating missing data: a listwise deleted sample, a pairwise deleted sample, and a multiple imputation (MI) sample. The MI sample (n=16,879) was most appropriate for addressing missing data. No CHD risk factor had better than marginal interrater agreement (κ>.60). High-density lipoprotein cholesterol (HDL-C) exhibited suboptimal interrater agreement that deteriorated (eg, κ<.30) as overall CHD risk increased. Conversely, low-density lipoprotein cholesterol (LDL-C) interrater agreement improved (eg, up to κ=.25) as overall CHD risk increased. Overall CHD risk of the sample was lower than comparative population-based CHD risk (ie, no more than 15% risk of CHD for the sample vs up to a 30% chance of CHD for the population). Interventions are needed to improve knowledge of CHD risk factors. Specific interventions should address perceptions of HDL-C and LCL-C. Internet-based health risk assessments such as Heart Aware may contribute to public health surveillance, but they must address selection bias of Internet-based recruitment methods.

Most theoretical formulations acknowledge that knowledge and awareness of cancer screening and prevention recommendations significantly influence health behaviors. This study compares perceived knowledge of cancer prevention and screening with test-based knowledge in a community sample. We also examine demographic variables and self-reported cancer screening and prevention behaviors as correlates of both knowledge scores, and consider whether cancer related knowledge can be accurately assessed using just a few, simple questions in a short and easy-to-complete survey. We used a community-partnered participatory research approach to develop our study aims and a survey. The study sample was composed of 180 predominantly African American and Hispanic community individuals who participated in a full-day cancer prevention and screening promotion conference in South Los Angeles, California, on July 2011. Participants completed a self-administered survey in English or Spanish at the beginning of the conference. Our data indicate that perceived and test-based knowledge scores are only moderately correlated. Perceived knowledge score shows a stronger association with demographic characteristics and other cancer related variables than the test-based score. Thirteen out of twenty variables that are examined in our study showed a statistically significant correlation with the perceived knowledge score, however, only four variables demonstrated a statistically significant correlation with the test-based knowledge score. Perceived knowledge of cancer prevention and screening was assessed with fewer items than test-based knowledge. Thus, using this assessment could potentially reduce respondent burden. However, our data demonstrate that perceived and test-based knowledge are separate constructs.

During solid dosage form manufacturing, the uniformity of dosage units (UDU) is ensured by testing samples at 2 stages, that is, blend stage and tablet compression or capsule/powder filling stage. The aim of this work is to propose a sample size selection approach based on quality risk management principles for process performance qualification (PPQ) and continued process verification (CPV) stages by linking UDU to potential formulation and process risk factors. Bayes success run theorem appeared to be the most appropriate approach among various methods considered in this work for computing sample size for PPQ. The sample sizes for high-risk (reliability level of 99%), medium-risk (reliability level of 95%), and low-risk factors (reliability level of 90%) were estimated to be 299, 59, and 29, respectively. Risk-based assignment of reliability levels was supported by the fact that at low defect rate, the confidence to detect out-of-specification units would decrease which must be supplemented with an increase in sample size to enhance the confidence in estimation. Based on level of knowledge acquired during PPQ and the level of knowledge further required to comprehend process, sample size for CPV was calculated using Bayesian statistics to accomplish reduced sampling design for CPV.

Information from the Human Genome Project (HGP) and the integration of information from related areas of study and technology will dramatically change health care for the craniofacial complex. Approaches to risk assessment and diagnosis, prevention, early intervention, and management of craniofacial conditions are and will continue to evolve through the application of this new knowledge. While this information will advance our health care abilities, it is clear that the dental profession will face challenges regarding the acquisition, application, transfer, and effective and efficient use of this knowledge with regards to dental research, dental education, and clinical practice. Unraveling the human genomic sequence now allows accurate diagnosis of numerous craniofacial conditions. However, the greatest oral disease burden results from dental caries and periodontal disease that are complex disorders having both hereditary and environmental factors determining disease risk, progression, and course. Disease risk assessment, prevention, and therapy, based on knowledge from the HGP, will likely vary markedly for the different complex conditions affecting the head and neck. Integration of Information from the human genome, comparative and microbial genomics, proteomics, bioinformatics, and related technologies will provide the basis for proactive prevention and intervention and novel and more efficient treatment approaches. Oral health care practitioners will increasingly require knowledge of human genetics and the application of new molecular-based diagnostic and therapeutic technologies.

Most women are unaware of the risk factors for osteoporosis (OP). In an effort to prevent the development of OP, women need to have a raised awareness on this issue. The aims of this study were to determine any differences in the level of awareness and knowledge about OP between pre- and postmenopausal women. Three hundred and six women who presented to the outpatient clinic of the Physical Medicine and Rehabilitation Department were included into the study. Demographic characteristics of the subjects were recorded. The participants were interviewed via an OP awareness questionnaire, which was designed to determine their knowledge of OP and risk factors. The mean ages of the 126 pre- and 180 postmenopausal women were 41.3 ± 5.9 and 58.9 ± 8.1 years, respectively. Thirty-two percent of premenopausal and 51% of postmenopausal women had heard about OP (p< 0.001), but the mean scores of OP knowledge according to the OP questionnaire were not different between the groups (p> 0.05). Both pre- and postmenopausal women with a higher level of education demonstrated better knowledge of OP based on their awareness questionnaire score (p< 0.001). Although half of the pre- and postmenopausal women reported having some awareness of OP, their level of knowledge was poor, particularly with regard to the risk factors associated with the condition and its complications. Having information about the risks of OP and a better understanding of the health beliefs of those at risk are important, as both may play a major role in influencing an individual's OP-preventing behaviors.

To analyse knowledge, attitudes and sexual practices on HIV/AIDS, and estimate HIV prevalence among residents of Sucre (Bolivia). Population-based survey of residents aged 15-49 randomly selected during 2008/2009. Blood samples were collected on Whatman-filter paper and tested with enzyme-linked immunosorbent assay. Knowledge on HIV/AIDS, sexual risk practices and discriminatory attitudes against people living with HIV/AIDS (PLWHA) were modelled with multiple logistic regression. Of 1499 subjects, 59% were women. All subjects were HIV-negative. Inadequate knowledge of HIV/AIDS transmission and prevention was observed in 67% and risk factors varied by gender (interaction p-value<0.05). Discriminatory attitudes were displayed by 85% subjects; associated factors were: rural residence, low educational level and low income. Unsafe sex was reported by 10%; risk factors varied by residence area (interaction p-value<0.05). In urban areas, risk factors were male sex, younger age and being in common-law union. Prevalence of HIV infection is very low and unsafe sex is relatively uncommon. Inadequate knowledge on HIV/AIDS and discriminatory attitudes towards PLWHA are extremely high and are associated to gender, ethnic and economic inequalities. Copyright © 2015 Elsevier Editora Ltda.

This study aims to broaden the scope of knowledge on the role of direct-to-consumer prescription drug advertising (DTCA) in the construction of consumers' optimistic bias regarding health issues and their intentions for coping actions. Based on an online survey of U.S. adults aged 65 years or older (N = 622), this study revealed that (a) respondents were optimistically biased in estimating their future risk of Alzheimer's disease (AD); (b) exposure to DTCA for AD medicine related negatively to optimistic bias when respondents had a low level of knowledge about AD, while the relationship disappeared when knowledge was high; (c) optimistic bias was negatively associated with intentions to seek information about AD and professional help to discuss it; and (d) optimistic bias mediated the relationship between the DTCA exposure × AD knowledge interaction and information- and help-seeking intentions. Implications for the theory and practice of DTCA are discussed.

Background Many healthy women consider genetic testing for breast cancer risk, yet BRCA testing issues are complex. Objective Determining whether an intelligent tutor, BRCA Gist, grounded in fuzzy-trace theory (FTT), increases gist comprehension and knowledge about genetic testing for breast cancer risk, improving decision-making. Design In two experiments, 410 healthy undergraduate women were randomly assigned to one of three groups: an online module using a web-based tutoring system (BRCA Gist) that uses artificial intelligence technology, a second group read highly similar content from the NCI web site, and a third completed an unrelated tutorial. Intervention BRCA Gist applied fuzzy trace theory and was designed to help participants develop gist comprehension of topics relevant to decisions about BRCA genetic testing, including how breast cancer spreads, inherited genetic mutations, and base rates. Measures We measured content knowledge, gist comprehension of decision-relevant information, interest in testing, and genetic risk and testing judgments. Results Control knowledge scores ranged from 54% to 56%, NCI improved significantly to 65% and 70%, and BRCA Gist improved significantly more to 75% and 77%, p<.0001. BRCA Gist scored higher on gist comprehension than NCI and control, p<.0001. Control genetic risk-assessment mean was 48% correct; BRCA Gist (61%), and NCI (56%) were significantly higher, p<.0001. BRCA Gist participants recommended less testing for women without risk factors (not good candidates), (24% and 19%) than controls (50%, both experiments) and NCI, (32%) Experiment 2, p<.0001. BRCA Gist testing interest was lower than controls, p<.0001. Limitations BRCA Gist has not been tested with older women from diverse groups. Conclusions Intelligent tutors, such as BRCA Gist, are scalable, cost effective ways of helping people understand complex issues, improving decision-making. PMID:24829276

Wealth inequality as a predictor of HIV-related knowledge in Nigeria.

Considering the high state-level heterogeneity of HIV prevalence and socioeconomic characteristics in Nigeria, it is a relevant setting for studies into the socioeconomic correlates of HIV-related knowledge. Although the relationship between absolute poverty and HIV transmission has been studied, the role of wealth inequality in the dynamics of the HIV epidemic has yet to be investigated in Nigeria. The current study, therefore, investigates wealth inequality and other sociodemographic covariates as predictors of HIV-related knowledge, in order to identify subgroups of the Nigerian population that would benefit from HIV preventive interventions. This study used the nationally representative 2013 Nigerian Demographic and Health Survey (NDHS). HIV-related knowledge was computed as a total score based on HIV-related knowledge indicators in the NDHS, dichotomised using the sample median as the cut-off. Wealth inequality and other relevant sociodemographic variables were introduced into a logistic regression model based on their significance in bivariate analyses. ORs derived from the model were interpreted to identify risk groups for low HIV-related knowledge after adjusting for confounding factors. The regression model indicated that individuals with lower literacy levels were almost twice as likely as literate respondents to have low HIV-related knowledge (adjusted OR (AOR): 1.95, 95% CI 1.85 to 2.05, P<0.001), and individuals in the upper wealth quintile were less than half as likely than those in the lower wealth quintile to have low HIV-related knowledge (AOR: 0.40, 95% CI 0.35 to 0.46, P<0.001). Women were also more than twice as likely as men to have low HIV-related knowledge at each level of wealth inequality. In addition, women were 80% less likely to have low mother-to-child transmission knowledge than men, but had over 1.5 times higher odds of having poor knowledge of HIV risk reduction measures. Ethnicity, religious affiliation, relationship status and residing in rural areas were additional significant predictors of HIV-related knowledge. HIV-related knowledge in this sample is generally low among women, those with low literacy levels, the poor, the unemployed, those residing in rural areas, those with traditional religious beliefs and those living in states with the highest wealth inequality ratios. The identification of these risk groups for low HIV-related knowledge facilitates the implementation of future evidence-based interventions among these groups in order to potentially reduce HIV transmission.

To assess knowledge of cardiovascular disease (CVD) risk factors among a group of health screening participants and to compare knowledge between participants with high and low CVD risk. Cross-sectional pilot study. Jonesboro, AR, during June 2007. 121 adult volunteers participating in a community health screening. 34-item self-administered written questionnaire. Ability to identify CVD risk factors and healthy values for CVD risk factors and the differences in these abilities between participants with high and low CVD risk. Participants demonstrated good knowledge of traditional CVD risk factors such as high blood pressure, high cholesterol, lack of exercise, and overweight or obese status. Knowledge of other CVD risk factors and healthy values for major CVD risk factors was limited. Participants with high CVD risk were significantly more likely to correctly identify high triglycerides as a CVD risk factor and to identify healthy values for fasting blood glucose and total cholesterol compared with participants with low CVD risk. Overall, participants lacked knowledge of the risk factor status and healthy values for many CVD risk factors. Participants with high CVD risk may have better knowledge of some CVD risk factors than participants with low CVD risk. These findings highlight the need for more education to improve knowledge in both risk groups.

Public health campaigns have improved knowledge on UVR-associated skin cancer risk and increased sun protection awareness. However, tanned skin is still a common beauty ideal. The relationship between knowledge, attitudes and protective behavior is not fully understood yet. A population-based survey was thus performed in the district of Erlangen involving 2,619 parents of 3- to 6-year old children. By means of a self-administered standardized questionnaire parental knowledge about risk factors for skin cancer, their attitudes towards tanning and details of protective measures taken for their children were assessed. The study analyzed specifically the impact of parental tanning attitudes on sun-protective measures for their children while controlling for parental knowledge about skin cancer risk factors. While parental knowledge was significantly (inversely) associated with agreement to the statement "Tanned skin is healthy skin", this was not the case for "Tanning makes me look better". Overall, tanning affirmative attitudes were inversely associated with protective measures taken for the children, whereas parental knowledge had a positive impact on sun protection at the beach only. Multivariable analyses provided evidence for an effect of parental attitude on protective behavior independent of parental knowledge. Tanning attitudes and tanned skin as the misguided ideal of beauty need to be addressed in future public health campaigns to enhance the effectiveness of preventive activities in changing sun protective behavior.

The objective of this study was to develop new scales measuring knowledge and attitude about UVR and sun related behavior, and to examine their association to sun related behavior objectively measured by personal dosimetry. During May-August 2013, 664 Danes wore a personal electronic UV-dosimeter for one week that measured their UVR exposure. Afterwards, they answered a questionnaire on sun-related items. We applied descriptive analysis, linear and logistic regression analysis to evaluate the associations between the questionnaire scales and objective UVR measures. Perceiving protection as routine and important were positively correlated with protective behavior. Knowledge deficit of UV and risk of melanoma, perceived benefits and importance of protection behavior was also correlated with use of protection. ‘Knowledge deficit of UV and risk of melanoma and Perceived barrier towards sun avoidance between 12 and 15’ were both associated with increased risk of sunburn. Attitude towards tan was associated to both outdoor time and exposure as well as use of protection, but not to sunburn. The results regarding Knowledge deficit of UV and risk of melanoma associated to UVR exposure and Perceived barrier towards sun avoidance between 12 and 15 emphasize the importance of awareness of melanoma risk and the priority of the skin cancer prevention advice. Shifting activities to outside the suns peak-hours could be an approach for structural and campaign preventive measures. Knowledge of items predicting exposure to UVR, use of protection and sunburn are important for planning of preventive interventions and melanoma research. PMID:28542543

Objective To determine seniors’ beliefs about falls and design a fall-risk self-assessment and educational materials to promote early identification of evidence-based fall risks and encourage prevention behaviors. Methods Focus groups with community-dwelling seniors, conducted in two phases to identify perceptions about fall risks and risk reduction and to assess face validity of the fall-risk self-assessment and acceptability of educational materials. Results Lay perception of fall risks was in general concordance with evidence-based research. Maintaining independence and positive tone were perceived as key motivators for fall prevention. Seniors intended to use information in the educational tool to stimulate discussions about falls with health care providers. Implications An evidence-based, educational fall-risk self-assessment acceptable to older adults can build on existing lay knowledge about fall risks and perception that falls are a relevant problem and can educate seniors about their specific risks and how to minimize them.

Objective To investigate the adverse events and potential risk factors in patients who develop sepsis. Subjects and Methods Fifty-five medico-legal opinion forms relating to sepsis cases issued by the Department of Forensic Medicine, Wroclaw, Poland, between 2004 and 2013 were analyzed for medical errors and risk factors for adverse events. Results The most common causes of medical errors were a lack of knowledge in recognition, diagnosis and therapy as well as ignorance of risk. The common risk factors for adverse events were deferral of a diagnostic or therapeutic decision, high-level anxiety of patients or their families about the patient's health and actively seeking for help. The most significant risk factors were communication errors, not enough medical staff, stereotype-based thinking about diseases and providing easy explanations for serious symptoms. Conclusion The most common cause of adverse events related to sepsis in the Polish health-care system was a lack of knowledge about the symptoms, diagnosis and treatment as well as the ignoring of danger. A possible means of improving safety might be through spreading knowledge and creating medical management algorithms for all health-care workers, especially physicians. PMID:25501966

Volcanic risk: the responsibility of science in communication

NASA Astrophysics Data System (ADS)

Piccione, Caterina

2013-04-01

The knowledge of the places where we live comes both from the experience handed down from one generation to the other and from scientific knowledge. In some cases, natural risks are "invisible", such as earthquakes, in some other cases, natural risks are seemingly "invisible", such as a wall in danger of collapse or a valley in a flood zone. And besides all this, there is volcanic risk, where the power of the forces of nature appears in all its beauty and majesty. The possibility to see volcanoes, to perceive their changes, to observe them closely and the need to live with them, makes it very important for the population living in these areas to have an adequate knowledge of the risk, a knowledge that should be based on scientific research. In Italy the experience of the Istituto Nazionale di Geofisica e Vulcanologia in the Vesuvio area, in the Aeolian Islands and around Etna shows how vital it is to make people aware of volcanic risk. Thanks to the support of the scientific community, the population can develop the best possible coexistence with volcanoes and with the risk they represent. These are extreme situations, but they are the starting point for educational and informative activities continuing to evolve and upgrade in parallel to the availability of new technologies and media and the progress of research that INGV has been conducting for years through specific projects. The scientific community and individual researchers have the ethical duty to share with the community the knowledge on risk, a responsibility that becomes especially important in those areas affected by volcanic risk. It is from this educational action that depends on the awareness of the populations with regard to the risk they are exposed to, that results in a responsible behavior in case of emergency, and that becomes the main variable for the safety of communities coexisting with active volcanoes.

Infection control remains a key challenge for Tuberculosis (TB) control program with an increased risk of TB transmission among health care workers (HCWs), especially in settings with inadequate TB infection control measures. Poor knowledge among HCWs and inadequate infection control practices may lead to the increased risk of nosocomial TB transmission. An institution-based cross-sectional survey was conducted in 28 health facilities providing TB services in the Kathmandu Valley, Nepal. A total of 190 HCWs were assessed for the knowledge, attitudes and practices on TB infection control using a structured questionnaire. The level of knowledge on TB infection control among almost half (45.8%) of the HCWs was poor, and was much poorer among administration and lower level staff. The knowledge level was significantly associated with educational status, and TB training and/or orientation received. The majority (73.2%) of HCWs had positive attitude towards TB infection control. Sixty-five percent of HCWs were found to be concerned about being infected with TB. Use of respirators among the HCWs was limited and triage of TB suspects was also lacking. Overall knowledge and practices of HCWs on TB infection control were not satisfactory. Effective infection control measures including regular skill-based training and/or orientation for all categories of HCWs can improve infection control practices in health facilities.

Effective risk communication in transfusion medicine is important for health-care consumers, but understanding the numerical magnitude of risks can be difficult. The objective of this study was to determine the effect of a visual risk communication tool on the knowledge and perception of transfusion risk. Laypeople were randomly assigned to receive transfusion risk information with either a written or a visual presentation format for communicating and comparing the probabilities of transfusion risks relative to other hazards. Knowledge of transfusion risk was ascertained with a multiple-choice quiz and risk perception was ascertained by psychometric scaling and principal components analysis. Two-hundred subjects were recruited and randomly assigned. Risk communication with both written and visual presentation formats increased knowledge of transfusion risk and decreased the perceived dread and severity of transfusion risk. Neither format changed the perceived knowledge and control of transfusion risk, nor the perceived benefit of transfusion. No differences in knowledge or risk perception outcomes were detected between the groups randomly assigned to written or visual presentation formats. Risk communication that incorporates risk comparisons in either written or visual presentation formats can improve knowledge and reduce the perception of transfusion risk in laypeople.

Present the method used to elaborate and formalize current scientific knowledge to provide physicians with tools available on the Internet, that enable them to evaluate individual patient risk, give personalized preventive recommendations or early screening measures. The approach suggested in this article is in line with medical procedures based on levels of evidence (Evidence-based Medicine). A cyclical process for developing recommendations allows us to quickly incorporate current scientific information. At each phase, the analysis is reevaluated by experts in the field collaborating on the project. The information is formalized through the use of levels of evidence and grades of recommendations. GLIF model is used to implement recommendations for clinical practice guidelines. The most current scientific evidence incorporated in a cyclical process includes several steps: critical analysis according to the Evidence-based Medicine method; identification of predictive factors; setting-up risk levels; identification of prevention measures; elaboration of personalized recommendation. The information technology implementation of the clinical practice guideline enables physicians to quickly obtain personalized information for their patients. Cases of colorectal prevention illustrate our approach. Integration of current scientific knowledge is an important process. The delay between the moment new information arrives and the moment the practitioner applies it, is thus reduced.

We sought to develop and deploy a video-based smartphone-delivered mobile HIV Risk Reduction (mHIVRR) intervention to individuals in an addiction treatment clinic. We developed 3 video modules that consisted of a 10-minute HIVRR video, 11 acceptability questions, and 3 knowledge questions and deployed them as a secondary study within a larger study of ecological momentary and geographical momentary assessments. All 24 individuals who remained in the main study long enough completed the mHIVRR secondary study. All 3 videos met our a priori criteria for acceptability "as is" in the population: they achieved median scores of ≤2.5 on a 5-point Likert scale; ≤20% of the individuals gave them the most negative rating on the scale; a majority of the individuals stated that they would not prefer other formats over video-based smartphone-delivered one (all P < 0.05). Additionally, all of our video modules met our a priori criteria for feasibility: ≤20% of data were missing due to participant noncompliance and ≤20% were missing due to technical failure. We concluded that video-based mHIVRR education delivered via smartphone is acceptable, feasible and may increase HIV/STD risk reduction knowledge. Future studies, with pre-intervention assessments of knowledge and random assignment, are needed to confirm these findings.

Lesbian, gay, bisexual, and transgender (LGBT) youth show higher rates of sexual risk behaviors than heterosexual and cisgender youth; yet, most school-based sexual health education is largely heteronormative and cisnormative and does not recognize the spectrum of sexual and gender identity. New York City's Departments of Health and Education collaborated to create an LGBT-inclusive supplement to the Reducing the Risk curriculum and implement it in 21 South Bronx high schools. Teachers completed an electronic survey to report the number of students reached and an online log to measure curriculum adherence. Students were administered an anonymous 74-item pre- and posttest to measure demographics, sexual health knowledge, and student satisfaction with the curriculum. Chi-square and t tests were used to assess differences in student demographics and changes in knowledge scores. Reducing the Risk was implemented in 21 schools reaching 230 classes and 5,673 students; with 161 classes receiving the supplement. Teachers reported completing an average of 70% of LGBT supplement activities. Students who received the supplement reported higher satisfaction and greater knowledge scores than students who did not. New York City experience shows that being more inclusive of LGBT teens while implementing preexisting evidence-based sexual and reproductive health programs is possible and replicable.

Understanding Fear of Opportunism in Global Prize-Based Science Contests: Evidence for Gender and Age Differences

Global prize-based science contests have great potential for tapping into diverse knowledge on a global scale and overcoming important scientific challenges. A necessary step for knowledge to be utilized in these contests is for that knowledge to be disclosed. Knowledge disclosure, however, is paradoxical in nature: in order for the value of knowledge to be assessed, inventors must disclose their knowledge, but then the person who receives that knowledge does so at no cost and may use it opportunistically. This risk of potential opportunistic behavior in turn makes the inventor fearful of disclosing knowledge, and this is a major psychological barrier to knowledge disclosure. In this project, we investigated this fear of opportunism in global prize-based science contests by surveying 630 contest participants in the InnoCentive online platform for science contests. We found that participants in these science contests experience fear of opportunism to varying degrees, and that women and older participants have significantly less fear of disclosing their scientific knowledge. Our findings highlight the importance of taking differences in such fears into account when designing global prize-based contests so that the potential of the contests for reaching solutions to important and challenging problems can be used more effectively.

Family physicians (FPs) have a central role in the detection and management of child abuse. According to the literature, only 2-5% of initial reports of child abuse come from the medical profession. The objective of this study was to assess levels of knowledge of risk factors for child abuse by Family Physicians (FPs) and the attention that the physicians pay to these risk factors. We conducted a mixed-method survey based on semi-structured interviews. 50 FPs practicing in the Somme County (northern France) were interviewed with closed and open questions. The FPs' level of knowledge of risk factors for child abuse and obstacles in the detection of child abuse were assessed. The FPs' level of knowledge of risk factors for child abuse was similar to that reported in the literature. However, FPs knew little about the significant role of prematurity. Likewise, the FP's training did not seem to influence their knowledge of risk factors. Fear of an incorrect diagnosis was the main obstacle to reporting a suspected case. The FPs considered that they were often alone in dealing with a difficult situation and considered that the judicial system and the social services were not sufficiently active. Few FPs had actually received specific training in the detection and management of child abuse but many stated their need for this type of training. FPs encounter many obstacles in the detection of child abuse, which sometimes make the FP reluctant to report a suspected or potential case. Medical education need to be improved in this field.

Aim To enhance learning (knowledge, attitudes and practices) about the importance of family health history (FHH) information and familial risks. Methods A pre–post design with one group was employed in this study. Five learning sessions were conducted with a community-based sample (n = 75) recruited from five counties in Texas, USA. Each learning session included: a short online video; enactive instructions on how to use the online Surgeon General FHH tool; and a presentation on how to assess familial risks. Participants completed the pre–post knowledge, attitudes and practices questionnaires and the study's satisfaction survey, and participated in a short focus group interview. Results Participants’ average age was 48.1 ± 13.3 years. Over half of the participants (79%) were female, and 55% described themselves as non-Hispanic White. Our findings showed significant changes (p < 0.05) in participants’ specific knowledge about factors that affect their familial risks. Similarly, significant changes (p < 0.05) in participants’ attitudes toward familial risks assessment for common disease complications and confidence in controlling these risks have been documented. Participants’ reported a high level of satisfaction in using online FHH tools, yet no significant change (p > 0.05) was detected in their reported practices regarding sharing FHH information with their providers or relatives. Focus group interviews revealed that participants were uncertain about providers’ or relatives’ reactions to sharing FHH information. Conclusion Using different learning styles may have a significant impact on improving knowledge and attitudes about familial risks. PMID:23682294

To determine the effectiveness of a community-partnered risk communication intervention tailored for subsistence anglers in a public housing community. A one group, pretest, posttest design was used to test the effectiveness of the intervention in a sample (n=23, age range 18-75 years, 100% African American) of subsistence anglers residing in a public housing community in close proximity to a Superfund clean-up site. Face-to-face surveys were conducted at baseline and 3 months post the intervention to assess changes in knowledge and behaviors. A socioculturally appropriate risk communication intervention was developed, implemented, and evaluated in the targeted community. The risk communication included an interactive power point presentation, visual demonstration by a role model, and distribution of low literacy written materials, followed by a booster mailing of materials 1 month past the initial intervention. Evaluation measures included survey instruments on knowledge and self-reported fishing behaviors. Participants showed improved knowledge and behavior change related to trimming fish, consumption by pregnant women and children, and consumption of large fish. The sociocultured tailored risk communication intervention demonstrated promising outcomes in this community and should be evaluated in a larger population of subsistence anglers.

Examining Factors Affecting Attitudes toward Nuclear Power in Taiwan

NASA Astrophysics Data System (ADS)

Chan, Tzu-Jen

Nuclear power has become a major issue in Taiwan for several decades. The objective of the present study is to obtain evidence about the major determinants contributing to attitudes toward nuclear power, by investigating socioeconomic factors, environmental attitudes, knowledge of issues, trust, and risk perception, in shaping nuclear attitudes. A face-to-face survey was conducted using paper-based questionnaires from July 2014 to September 2014. Finally, 364 surveys were collected, of which 356 met validation requirements. The findings showed (1) knowledge of issues, trust in university scientists, trust in environmental groups, and risk perception directly influence attitudes toward nuclear power. (2) Risk perception is directly influenced by trust in nuclear authorities, trust in environmental groups, environmental attitudes, and party preference. (3) Gender, age, and party preference directly influence knowledge, trust in nuclear authorities, or trust in university scientists. The potential explanations and implications of findings are discussed.

2002-01-01

Incorporating risk-based design as an integral part of spacecraft development is becoming more and more common. Assessment of uncertainties associated with design parameters and environmental aspects such as loading provides increased knowledge of the design and its performance. Results of such studies can contribute to mitigating risk through a system-level assessment. Understanding the risk of an event occurring, the probability of its occurrence, and the consequences of its occurrence can lead to robust, reliable designs. This paper describes an approach to risk-based structural design incorporating damage-tolerance analysis. The application of this approach to a candidate Earth-entry vehicle is described. The emphasis of the paper is on describing an approach for establishing damage-tolerant structural response inputs to a system-level probabilistic risk assessment.

Scott, Bobby R.; Lin, Yong; Wilder, Julie

2015-03-01

Our main research objective was to determine the biological bases for low-dose, radiation-induced adaptive responses in the lung, and use the knowledge gained to produce an improved risk model for radiation-induced lung cancer that accounts for activated natural protection, genetic influences, and the role of epigenetic regulation (epiregulation). Currently, low-dose radiation risk assessment is based on the linear-no-threshold hypothesis, which now is known to be unsupported by a large volume of data.

Ethnicity and HIV risk behaviour, testing and knowledge in Guatemala.

Taylor, Tory M; Hembling, John; Bertrand, Jane T

2015-01-01

To describe levels of risky sexual behaviour, HIV testing and HIV knowledge among men and women in Guatemala by ethnic group and to identify adjusted associations between ethnicity and these outcomes. Data on 16,205 women aged 15-49 and 6822 men aged 15-59 from the 2008-2009 Encuesta Nacional de Salud Materno Infantil were used to describe ethnic group differences in sexual behaviour, HIV knowledge and testing. We then controlled for age, education, wealth and other socio-demographic factors in a multivariate logistic regression model to examine the effects of ethnicity on outcomes related to age at sexual debut, number of lifetime sex partners, comprehensive HIV knowledge, HIV testing and lifetime sex worker patronage (men only). The data show low levels of risky sexual behaviour and low levels of HIV knowledge among indigenous women and men, compared to other respondents. Controlling for demographic factors, indigenous women were more likely than other women never to have been tested for HIV and to lack comprehensive HIV knowledge. They were less likely to report early sexual debut and three or more lifetime sexual partners. Indigenous men were more likely than other men to lack comprehensive HIV knowledge and demonstrated lower odds of early sexual debut, 10 or more lifetime sexual partners and sex worker patronage. The Mayan indigenous population in Guatemala, while broadly socially vulnerable, does not appear to be at elevated risk for HIV based on this analysis of selected risk factors. Nonetheless, low rates of HIV knowledge and testing may be cause for concern. Programmes working in indigenous communities should focus on HIV education and reducing barriers to testing. Further research into the factors that underlie ethnic self-identity and perceived ethnicity could help clarify the relative significance of these measures for HIV risk and other health outcomes.

To determine the level of awareness and knowledge of HIV postexposure prophylaxis (HIV PEP) and determinants of adequate knowledge among Family Physicians in Nigeria. This was a cross-sectional questionnaire-based survey conducted among 175 Family Physicians at two national conferences. Majority (97.7%) of the respondents was aware of the concept of HIV PEP and 99.4% believed it was effective in preventing HIV transmission. Over two third of our respondents had been exposed to NSI; however, less than 25% of those exposed received PEP. There was high level of knowledge of the various high-risk body fluids as well as types of high-risk exposures. 93.9% of our respondents knew that HIV PEP should commence within 1 h of exposure, 83.3% knew the correct duration of HIV PEP, but only 57.0% knew the ideal PEP regimen for high-risk exposures. The total mean score for our respondents was 17.8±2.9 with 79.4% having an adequate score. Being a junior doctor and male sex were associated with adequate knowledge. This study shows that despite high levels of awareness and knowledge of HIV PEP, access to its use among family physicians in Nigeria is still sub-optimal.

There are limited data on lesbian, gay, bisexual, and transgender (LGBT) healthcare experiences and interactions with the providers. This study assessed knowledge, attitudes, and practice behaviors of oncology providers regarding LGBT health. A 32-item web-based survey was emailed to 388 oncology providers at a single institution. The survey assessed: demographics, knowledge, attitudes, and practice behaviors. 108 providers participated in the survey (28% response rate). <50% answered knowledge questions correctly. 94% stated they were comfortable treating this population. 26% actively inquired about a patient's sexual orientation when taking a history. 36% felt the need for mandatory education on LGBT cultural competency at the institution. Results from the open comments section identified multiple misconceptions. This study revealed knowledge gaps about LGBT health risks. Cultural competency training may aid oncology providers to understand the need to inquire about patients' gender identity and sexual orientation. Health care providers who incorporate the routine collection of gender identity and sexual orientation (SOGI) in their patient history taking may improve patient care by offering tailored education and referrals. While identifying as LGBT does not in itself increase risk for adverse health outcomes, this population tends to have increased risk behaviors. Copyright © 2016 Elsevier Ireland Ltd.

BACKGROUND Hepatitis C virus (HCV) is a major cause of chronic liver disease and cancer. Vietnamese Americans are at high risk of HCV infection, with men having the highest US incidence of liver cancer. This study examines an intervention to improve HCV knowledge among Vietnamese Americans. STUDY Seven Vietnamese community-based organizations in Pennsylvania and New Jersey recruited a total of 306 Vietnamese participants from 2010 to 2011. RESULTS Average knowledge scores for pretest and posttest were 3.32 and 5.88, respectively (maximum 10). After adjusting for confounding variables, age and higher education were positively associated with higher pretest scores and having a physician who spoke English or Vietnamese was negatively associated with higher pretest scores. Additionally, after adjusting for confounding variables, household income, education, and having an HCV-infected family member significantly increased knowledge scores. CONCLUSIONS Promotion and development of HCV educational programs can increase HCV knowledge among race and ethnic groups, such as Vietnamese Americans. Giving timely information to at-risk groups provides the opportunity to correct misconceptions, decrease HCV risk behaviors, and encourage testing that might improve timely HCV diagnosis and treatment.

Hazard perception, risk perception, and the need for decontamination by residents exposed to soil pollution: the role of sustainability and the limits of expert knowledge.

PubMed

Vandermoere, Frédéric

2008-04-01

This case study examines the hazard and risk perception and the need for decontamination according to people exposed to soil pollution. Using an ecological-symbolic approach (ESA), a multidisciplinary model is developed that draws upon psychological and sociological perspectives on risk perception and includes ecological variables by using data from experts' risk assessments. The results show that hazard perception is best predicted by objective knowledge, subjective knowledge, estimated knowledge of experts, and the assessed risks. However, experts' risk assessments induce an increase in hazard perception only when residents know the urgency of decontamination. Risk perception is best predicted by trust in the risk management. Additionally, need for decontamination relates to hazard perception, risk perception, estimated knowledge of experts, and thoughts about sustainability. In contrast to the knowledge deficit model, objective and subjective knowledge did not significantly relate to risk perception and need for decontamination. The results suggest that residents can make a distinction between hazards in terms of the seriousness of contamination on the one hand, and human health risks on the other hand. Moreover, next to the importance of social determinants of environmental risk perception, this study shows that the output of experts' risk assessments-or the objective risks-can create a hazard awareness rather than an alarming risk consciousness, despite residents' distrust of scientific knowledge.

Cioe, Patricia A; Crawford, Sybil L; Stein, Michael D

2014-01-01

Cardiovascular disease (CVD) has emerged as a major cause of morbidity and mortality in HIV-infected adults. Research in noninfected populations has suggested that knowledge of CVD risk factors significantly influences perceptions of risk. This cross-sectional study describes CVD risk factor knowledge and risk perception in HIV-infected adults. We recruited 130 HIV-infected adults (mean age = 48 years, 62% male, 56% current smokers, mean years since HIV diagnosis, 14.7). The mean CVD risk factor knowledge score was fairly high. However, controlling for age, CVD risk factor knowledge was not predictive of perceived risk [F(1, 117) = 0.13, p > .05]. Estimated risk and perceived risk were weakly but significantly correlated; r (126) = .24, p = .01. HIV-infected adults are at increased risk for CVD. Despite having adequate risk-factor knowledge, CVD risk perception was inaccurate. Improving risk perception and developing CVD risk reduction interventions for this population are imperative.

2013-01-01

As planning continues for commercial spaceflight, attention is turned to NASA to assess whether its human system risk management approach can be applied to mitigate the risks associated with commercial suborbital and orbital flights. NASA uses a variety of methods to assess the risks to the human system based on their likelihood and consequences. In this article, we review these methods and categorize the risks in the system as "definite," "possible," or "least" concern for commercial spaceflight. As with career astronauts, these risks will be primarily mitigated by screening and environmental control. Despite its focus on long-duration exploration missions, NASA's human system risk management approach can serve as a preliminary knowledge base to help medical planners prepare for commercial spaceflights.

Climate change is a risk management challenge for society, with uncertain but potentially severe outcomes affecting natural and human systems, across generations. Managing climate-related risks will be more difficult without a base of knowledge and practice aimed at identifying and evaluating specific risks, and their likelihood and consequences, as well as potential actions to promote resilience in the face of these risks. Here, we suggest three improvements to the process of conducting climate change assessments to better characterize risk and inform risk management actions.

Cardiovascular diseases are a public health concern everywhere, especially ischemic or coronary heart diseases (CHD) which are on top of causes list of mortality and morbidity in both genders globally. From which nearly 80% can be because of modifiable risks. In Egypt, there is a lack of studies on the knowledge of people about coronary heart diseases and its modifiable risks. So, this research reported here we designed to measure the dimensions of peoples knowledge about CHD and their attitude towards prevention, and to identify the main risk reduction barriers. By using comprehensive cross-sectional, descriptive research design, all adult individuals attending the family health clinic at Suez Canal University Hospital were eligible for inclusion with total number 125 participants. An interview questionnaire designed and used to collect data. The study revealed that (10.4%) of participants had a history of CHD, and (7.2%) had a family history of CHD. 79.2% Had a satisfactory total knowledge about CHD, and (94.4%) had a positive total attitude towards prevention. Risk reduction barriers as a medical setting barriers were (24%), patient related barriers were (22.4%). Community-societal barriers were almost the same as knowledge barriers which were around (16%). At last the systemic-organizational barriers were (9.6%). The findings settled that, total knowledge about CHD was satisfactory but lower than the level total of attitude. More effort the health system needs to improve the settings and engage patients in their plans and breaking related barriers, with development of health education programs based on needs assessment. Further studies we recommend to explore the reasons and follow up the changes.

To assess college students' knowledge and perception of cardiovascular risk factors and to screen for their cardiovascular risks. The final sample that responded to recruitment consisted of 158 college students from a midwestern university. A cross-sectional, descriptive study was performed using convenience sampling. College students were knowledgeable about cardiovascular risk factors but did not perceive themselves at risk for cardiovascular disease (CVD). Knowledge of cardiovascular risk factors was correlated with the lifetime risk estimates (ρ = .17, p = .048), and perception of cardiovascular risk was positively associated with 30-year CVD risk estimates (ρ = .16, p = .048). More than 50% of the participants had 1 or more cardiovascular risk factors. High knowledge level of cardiovascular risk factors was not sufficient to lower cardiovascular risks within this study population, but changing perception of cardiovascular risk factors may play a bigger role in reducing long-term cardiovascular risks.

Development of the Nutrition4Kids website.

2012-01-01

According to the 2009 National Vital Statistics Report, cancer is the second-leading cause of death in the United States. Researchers have determined that consuming a diet low in fruits, vegetables, and whole grains is a common risk factor associated with the risk of developing several types of cancer including stomach, colorectal, breast, and pancreatic. Currently, there are few websites devoted to increasing students' knowledge about the role of a healthy diet in cancer prevention. The Nutrition4Kids website is a unique health education tool that targets youth aged 10 to 14 years. The website content and design were based on the Health Belief Model, the Information-Motivation and Behavioral Skills Model, and the principles of health literacy. The information included on the website was based on recommendations from the American Institute for Cancer Research and the World Cancer Research Fund. The website contains nutrition information, recipes that emphasize the consumption of fruits, vegetables, and whole grains, and interactive games. The primary objectives of the Nutrition4Kids website are to 1) increase students' knowledge of how poor dietary habits can affect their health, 2) increase students' knowledge of healthy dietary habits that can reduce their risk for cancer, 3) increase students' ability to prepare healthy, well-balanced meals and snacks, 4) increase students' ability to discuss healthy eating with their family and friends, and 5) increase students' knowledge of nutrients that have healthful benefits.

Psoriasis is a common long-term, immune-mediated skin condition associated with behavioural factors (e.g. smoking, excess alcohol, obesity), which increase the risk of psoriasis onset, flares and comorbidities. Motivational interviewing (MI) is an evidence-based approach to health-related behaviour change that has been used successfully for patients with long-term conditions. This study assessed change in clinicians' MI skills and psoriasis knowledge following Psoriasis and Wellbeing (Pso Well ® ) training. To investigate whether the Pso Well training intervention improves clinicians' MI skills and knowledge about psoriasis-related comorbidities and risk factors; and to explore the acceptability and feasibility of the Pso Well training content, delivery and evaluation. Clinicians attended the 1-day training programme focused on MI skills development in the context of psoriasis. MI skills were assessed pre- and post-training using the Behaviour Change Counselling Index. Knowledge about psoriasis-related comorbidity and risk factors was assessed with a novel 22-point measure developed for the study. Interviews with clinicians were analysed qualitatively to identify perceptions about the feasibility and acceptability of the training. Sixty-one clinicians completed the training (35 dermatology nurses, 23 dermatologists and three primary-care clinicians). Clinicians' MI skills (P < 0·001) and knowledge (P < 0·001) increased significantly post-training. Clinicians found the training valuable and relevant to psoriasis management. Attendance at the Pso Well training resulted in improvements in clinicians' knowledge and skills to manage psoriasis holistically. Clinicians deemed the training itself and the assessment procedures used both feasible and acceptable. Future research should investigate how this training may influence patient outcomes. © 2016 British Association of Dermatologists.

2013-01-01

In Germany the implementation of human papillomavirus (HPV) vaccination for women aged 12-17 years was accompanied by various campaigns. Evidence-based information including numerical data was not provided. However, standard information leads to overestimation of cancer risk and effects of HPV vaccination. Confidence in children's ability to deal with numerical data is low, especially in disadvantaged pupils. The aim of the present study was to compare the effects of a standard leaflet with an information leaflet supplemented with numerical data on 'risk knowledge' regarding HPV vaccination among schoolgirls. Randomised-controlled short-term trial. All 108 schoolgirls of seven school classes were asked to participate and 105 agreed. Participants were vocational schoolgirls who were preparing for grade 10 graduation and who were members of the target group for HPV vaccination. The control group was asked to read a standard leaflet on HPV vaccination of the German Women's Health Network. The intervention group received the same leaflet, but it was supplemented with numerical information on cancer risk and assumed effects of the HPV vaccination on cancer prevention. As baseline characteristics we surveyed: age, vaccination status, attitude towards HPV vaccination and aspects regarding migration background. The primary end point was 'risk knowledge'. Questionnaire surveys were performed under experimental conditions. Individual randomisation, participants, and intention-to-treat data analyses were blinded. The study was approved by the Ministry of Education and Culture of Schleswig-Holstein and the ethics committee of the Hamburg Chamber of Physicians. We analysed 'risk knowledge' for all 105 randomised participants. Baseline characteristics of the two groups were comparable. Numerical risk information recipients were more likely to give correct answers compared to standard information recipients: Mean value of risk knowledge score (0-5 points): 4.6±1.0 vs. 2.6±1.2 (mean difference 2.0 (95% CI 1.6-2.4)); (P<0.001). Post hoc distractor analysis of single items was performed. Incorrect answers of control participants indicated that cervical cancer risk was highly overestimated whereas total cancer risk was mostly underestimated, and possible impact of HPV vaccination on cancer prevention was overestimated. Supplementing health information on HPV vaccination with numerical data improves 'risk knowledge' among schoolgirls.

African Americans are disproportionately affected by type 2 diabetes. The purpose of this study was to assess to what extent African Americans' knowledge and awareness of family health history and related risk factors for developing type 2 diabetes influence their likelihood of adopting a preventive behavior. This study employed an anonymous pencil-and-paper, self-administered survey consisting of two sections. Section 1 was a modified version of the US Surgeon General's Family Health History Initiative and the American Diabetes Association Diabetes Risk Factor Survey. Section 2 of the survey was based on the constructs of the theory of planned behavior. Over 394 African American participants completed the survey. 'Perceived behavioral control' was the strongest predictor of 'likelihood of adopting preventive behavior'. Participants were aware of their family history as a risk factor for type 2 diabetes, but it was not a significant predictor of behavior modifications based on that knowledge. The lack of perceived risk in this population shows the importance of not only knowing one's risk factors but translating those risk factors to a more personalized form that fits into the current lifestyle of the individual in a meaningful way. © 2016 S.

Child welfare practitioners in many countries now have increased responsibility for assessing intimate partner violence (IPV) as part of their child risk assessment process. Much research-based knowledge has accumulated about IPV and its impact on children that can inform this process. This exploratory study examined the extent to which research-based knowledge in IPV is influencing what child welfare practitioners explore in relation to IPV during their assessment process. Using a focus group format, two cohorts of child welfare practitioners, one located in Dublin County, Ireland, and one from the New York City metropolitan area, were asked what information they deem critical to explore about IPV, why they explore this content, and how they explore it. Results indicated that a wide range of information about IPV was reported as gathered by both groups, however, explicit research knowledge was not identified as a major influence for exploring these areas. Standardized IPV risk assessment instruments were also not reported as used by any of the participants. Other influences, such as practice experience, social work education, and legal or regulatory directives, had a much greater influence on the social worker's information gathering process in relation to IPV than research.

Robust Derivation of Risk Reduction Strategies

Richardson, Julian; Port, Daniel; Feather, Martin

2007-01-01

Effective risk reduction strategies can be derived mechanically given sufficient characterization of the risks present in the system and the effectiveness of available risk reduction techniques. In this paper, we address an important question: can we reliably expect mechanically derived risk reduction strategies to be better than fixed or hand-selected risk reduction strategies, given that the quantitative assessment of risks and risk reduction techniques upon which mechanical derivation is based is difficult and likely to be inaccurate? We consider this question relative to two methods for deriving effective risk reduction strategies: the strategic method defined by Kazman, Port et al [Port et al, 2005], and the Defect Detection and Prevention (DDP) tool [Feather & Cornford, 2003]. We performed a number of sensitivity experiments to evaluate how inaccurate knowledge of risk and risk reduction techniques affect the performance of the strategies computed by the Strategic Method compared to a variety of alternative strategies. The experimental results indicate that strategies computed by the Strategic Method were significantly more effective than the alternative risk reduction strategies, even when knowledge of risk and risk reduction techniques was very inaccurate. The robustness of the Strategic Method suggests that its use should be considered in a wide range of projects.

In organisational theory there is an assumption that knowledge is used effectively in healthcare systems that perform well. Actors in healthcare systems focus on managing knowledge of clinical processes like, for example, clinical decision-making to improve patient care. We know little about connecting that knowledge to administrative processes like high-risk medical device procurement. We analysed knowledge-related factors that influence procurement and clinical procedures for orthopaedic medical devices in Mexico. We based our qualitative study on 48 semi-structured interviews with various stakeholders in Mexico: orthopaedic specialists, government officials, and social security system managers or administrators. We took a knowledge-management related perspective (i) to analyse factors of managing knowledge of clinical procedures, (ii) to assess the role of this knowledge and in relation to procurement of orthopaedic medical devices, and (iii) to determine how to improve the situation. The results of this study are primarily relevant for Mexico but may also give impulsion to other health systems with highly standardized procurement practices. We found that knowledge of clinical procedures in orthopaedics is generated inconsistently and not always efficiently managed. Its support for procuring orthopaedic medical devices is insufficient. Identified deficiencies: leaders who lack guidance and direction and thus use knowledge poorly; failure to share knowledge; insufficiently defined formal structures and processes for collecting information and making it available to actors of health system; lack of strategies to benefit from synergies created by information and knowledge exchange. Many factors are related directly or indirectly to technological aspects, which are insufficiently developed. The content of this manuscript is novel as it analyses knowledge-related factors that influence procurement of orthopaedic medical devices in Mexico. Based on our results we recommend that the procurement mechanism should integrate knowledge from clinical procedures adequately in their decision-making. Without strong guidance, organisational changes, and support by technological solutions to improve the generation and management of knowledge, procurement processes for orthopaedic high-risk medical devices will remain sub-optimal.

There is a significant need for raising the awareness and building the capacity of water professionals in different water sectors cross Europe. There is also a need for qualified graduates to implement the EU Flood Risk Directive (FRD). The main aim of this work is to prepare and build the capacity of both groups in flood risk management through identifying synergies, sharing knowledge, and strengthen partnerships between universities and different stakeholders(mainly water professionals). The specific objectives are to develop; a) Development of a dynamic and active tool that allows all target-groups/users to assess their knowledge about flood risk management. b) Development of an innovative, active and problem-based learning methodology for flood risk education and training. c)Development of flood related Vocational Education & Training (VET) modules for water professionals (involving the students to gain practical experience). This will include some modules for undergraduate students on flood risk management and protection.

The risk concept and its application in natural hazard risk management in Switzerland

NASA Astrophysics Data System (ADS)

Bründl, M.; Romang, H. E.; Bischof, N.; Rheinberger, C. M.

2009-05-01

Over the last ten years, a risk-based approach to manage natural hazards - termed the risk concept - has been introduced to the management of natural hazards in Switzerland. Large natural hazard events, new political initiatives and limited financial resources have led to the development and introduction of new planning instruments and software tools that should support natural hazard engineers and planners to effectively and efficiently deal with natural hazards. Our experience with these new instruments suggests an improved integration of the risk concept into the community of natural hazard engineers and planners. Important factors for the acceptance of these new instruments are the integration of end-users during the development process, the knowledge exchange between science, developers and end-users as well as training and education courses for users. Further improvements require the maintenance of this knowledge exchange and a mindful adaptation of the instruments to case-specific circumstances.

Uncertainty is inherent in model-based forecasts of ecological invasions. In this chapter, we explore how the perceptions of that uncertainty can be incorporated into the pest risk assessment process. Uncertainty changes a decision maker’s perceptions of risk; therefore, the direct incorporation of uncertainty may provide a more appropriate depiction of risk. Our...

A multi-disciplinary approach to evaluate pluvial floods risk under changing climate: The case study of the municipality of Venice (Italy).

Global climate change is likely to pose increasing threats in nearly all sectors and across all sub-regions worldwide (IPCC, 2014). Particularly, extreme weather events (e.g. heavy precipitations), together with changing exposure and vulnerability patterns, are expected to increase the damaging effect of storms, pluvial floods and coastal flooding. Developing climate and adaptation services for local planners and decision makers is becoming essential to transfer and communicate sound scientific knowledge about climate related risks and foster the development of national, regional and local adaptation strategies. In order to analyze the effect of climate change on pluvial flood risk and advice adaptation planning, a Regional Risk Assessment (RRA) methodology was developed and applied to the urban territory of the municipality of Venice. Based on the integrated analysis of hazard, exposure, vulnerability and risk, RRA allows identifying and prioritizing targets and sub-areas that are more likely to be affected by pluvial flood risk due to heavy precipitation events in the future scenario 2041-2050. From the early stages of its development and application, the RRA followed a bottom-up approach taking into account the requests, knowledge and perspectives of local stakeholders of the North Adriatic region by means of interactive workshops, surveys and discussions. Results of the analysis showed that all targets (i.e. residential, commercial-industrial areas and infrastructures) are vulnerable to pluvial floods due to the high impermeability and low slope of the topography. The spatial pattern of risk mostly reflects the distribution of the hazard and the districts with the higher percentage of receptors' surface in the higher risk classes (i.e. very high, high and medium) are Lido-Pellestrina and Marghera. The paper discusses how risk-based maps and statistics integrate scientific and local knowledge with the final aim to mainstream climate adaptation in the development of risk mitigation and urban plans.

Passage of voter-driven marijuana reform laws signals a shift in public attitudes for marijuana use. For providers, legalization may necessitate practice modifications, particularly regarding patient-provider conversations about use and risk. We examined healthcare providers' knowledge of marijuana laws and health implications, professional practice behaviors, and attitudes about training. We surveyed 114 Colorado-based providers who care for children, adolescents, pregnant and breastfeeding women using a Venue-Day-Time survey methodology throughout Colorado. The survey captured providers' (e.g., physicians, nurses, medical assistants) knowledge of state marijuana laws, risk perceptions, counseling practices, and continued training needs. Providers were knowledgeable about marijuana laws, cautious supporting legalization, and perceived moderate to high risks, particularly for certain groups. About 50% of providers working with adolescents and pregnant or breastfeeding women assessed marijuana use "every" or "most" visits; 23% of those working with children reported such behavior. Conversations about specific risks varied between groups. Few providers felt completely knowledgeable about marijuana health risks and lacked confidence talking to patients about this issue. Providers frequently assess patients' marijuana use; however, they are uncomfortable and inconsistent talking to patients about specific marijuana health effects. Additional education is warranted, particularly as it relates to talking to patients about the danger of second hand smoke exposure, underage use, safe storage, and the over-consumption of edibles.

2017-06-25

Background: Data mining, a new concept introduced in the mid-1990s, can help researchers to gain new, profound insights and facilitate access to unanticipated knowledge sources in biomedical datasets. Many issues in the medical field are concerned with the diagnosis of diseases based on tests conducted on individuals at risk. Early diagnosis and treatment can provide a better outcome regarding the survival of lung cancer patients. Researchers can use data mining techniques to create effective diagnostic models. The aim of this study was to evaluate patterns existing in risk factor data of for mortality one year after thoracic surgery for lung cancer. Methods: The dataset used in this study contained 470 records and 17 features. First, the most important variables involved in the incidence of lung cancer were extracted using knowledge discovery and datamining algorithms such as naive Bayes, maximum expectation and then, using a regression analysis algorithm, a questionnaire was developed to predict the risk of death one year after lung surgery. Outliers in the data were excluded and reported using the clustering algorithm. Finally, a calculator was designed to estimate the risk for one-year post-operative mortality based on a scorecard algorithm. Results: The results revealed the most important factor involved in increased mortality to be large tumor size. Roles for type II diabetes and preoperative dyspnea in lower survival were also identified. The greatest commonality in classification of patients was Forced expiratory volume in first second (FEV1), based on levels of which patients could be classified into different categories. Conclusion: Development of a questionnaire based on calculations to diagnose disease can be used to identify and fill knowledge gaps in clinical practice guidelines.

To assess the impact of the education program of the Eye Care Quality and Accessibility Improvement in the Community (EQUALITY) telemedicine program on at-risk patients' knowledge about glaucoma and attitudes about eye care as well as to assess patient satisfaction with EQUALITY. New or existing patients presenting for a comprehensive eye exam (CEE) at one of two retail-based primary eye clinics were enrolled based on ≥1 of the following at-risk criteria for glaucoma: African Americans ≥40 years of age, Whites ≥50 years of age, diabetes, family history of glaucoma, and/or preexisting diagnosis of glaucoma. A total of 651 patients were enrolled. A questionnaire was administered prior to the patients' CEE and prior to the patients receiving any of the evidence-based eye health education program; a follow-up questionnaire was administered 2-4 weeks later by phone. Baseline and follow-up patient responses regarding knowledge about glaucoma and attitudes about eye care were compared using McNemar's test. Logistic regression models were used to assess the association of patient-level characteristics with improvement in knowledge and attitudes. Overall patient satisfaction was summarized. At follow-up, all patient responses in the knowledge and attitude domains significantly improved from baseline (P≤0.01 for all questions). Those who were unemployed (odds ratio =0.63, 95% confidence interval =0.42-0.95, P=0.026) or had lower education (odds ratio =0.55, 95% confidence interval =0.29-1.02, P=0.058) were less likely to improve their knowledge after adjusting for age, sex, race, and prior glaucoma diagnosis. This association was attenuated after further adjustment for other patient-level characteristics. Ninety-eight percent (n=501) of patients reported being likely to have a CEE within the next 2 years, whereas 63% (n=326) had a CEE in the previous 2 years. Patient satisfaction with EQUALITY was high (99%). Improved knowledge about glaucoma and a high intent to pursue eye care may lead to improved detection of early disease, thus lowering the risk of blindness.

Ground-based research with heavy ions for space radiation protection

NASA Astrophysics Data System (ADS)

Durante, M.; Kronenberg, A.

Human exposure to ionizing radiation is one of the acknowledged potential showstoppers for long duration manned interplanetary missions. Human exploratory missions cannot be safely performed without a substantial reduction of the uncertainties associated with different space radiation health risks, and the development of effective countermeasures. Most of our knowledge of the biological effects of heavy charged particles comes from accelerator-based experiments. During the 35th COSPAR meeting, recent ground-based experiments with high-energy iron ions were discussed, and these results are briefly summarised in this paper. High-quality accelerator-based research with heavy ions will continue to be the main source of knowledge of space radiation health effects and will lead to reductions of the uncertainties in predictions of human health risks. Efforts in materials science, nutrition and pharmaceutical sciences and their rigorous evaluation with biological model systems in ground-based accelerator experiments will lead to the development of safe and effective countermeasures to permit human exploration of the Solar System.

2017-01-01

This paper examines how to develop a Model for Knowledge Management System (KMS) for diabetes complication diseases. People with diabetes have a higher risk of developing a series of serious health problems. Each patient has different condition that could lead to different disease and health problem. But, with the right information, patient could have early detection so the health risk could be minimized and avoided. Hence, the objective of this research is to propose a conceptual framework that integrates social network model, Knowledge Management activities, and content based reasoning (CBR) for designing such a diabetes health and complication disease KMS. The framework indicates that the critical knowledge management activities are in the process to find similar case and the index table for algorithm to fit the framework for the social media. With this framework, KMS developers can work with healthcare provider to easily identify the suitable IT associated with the CBR process when developing a diabetes KMS.

Background: Although South Asians are at higher risk for coronary heart disease (CHD) than most other U.S. racial/ethnic groups, very little research has addressed this disparity. Purpose: As a first step in developing culturally targeted CHD prevention messages for this rapidly growing community, this study examined South Asians' knowledge and beliefs about CHD. Methods: Analyses, conducted in 2009, were based on data collected from January–July 2008 in a cross-sectional study population of 270 South Asian adults in Illinois. Interviews were conducted in English, Hindi, or Urdu using a standardized questionnaire. Multivariate regression models were used to examine the associations between sociodemographics and CHD knowledge and attitudes about preventability. Results: Eighty-one percent of respondents had one or more CHD risk factors. Most participants (89%) said they knew little or nothing about CHD. Stress was the most frequently mentioned risk factor (44%). Few mentioned controlling blood pressure (11%), cholesterol (10%), and diabetes (5%) for prevention. Fifty-three percent said that heart attacks are not preventable. Low education level, being interviewed in Urdu or Hindi, and low level of acculturation were associated with less knowledge and believing that CHD is not preventable. Conclusions: A majority of South Asians in this study believed that CHD is not preventable and had low awareness of modifiable risk factors. As a first step, CHD education should target the knowledge gaps that may affect risk factor control and behavior change. Education messages may need to be somewhat different for subgroups (e.g., by education and language) to be maximally effective. PMID:20307813

Knowledge, attitudes and practices of dental hygienists regarding caries management by risk assessment.

Urban, Ruth A; Rowe, Dorothy J

2015-02-01

The purpose of this study was to survey dental hygienists to determine their knowledge, attitudes and practices regarding the implementation of caries risk assessment, particularly caries management by risk assessment (CAMBRA), in private dental practices. A 17 item survey was developed to evaluate dental hygienists' knowledge, attitudes and practices related to CAMBRA and perceived barriers to CAMBRA implementation in private dental practice. Surveys were mailed to a randomized sample of 1,000 dental hygienists licensed to practice in California. Responses were tabulated for each respondent, and the response frequency for each survey item was calculated. Respondents' comments to the open-ended question were compiled, according to themes. The response rate was 18%. Only 66% of the respondents were familiar with the term CAMBRA, although 89% agreed with its underlying principles of risk assessment. CAMBRA protocol had been implemented in 40% of the respondents' employment sites. Respondents disagreed that time (45%) and cost of products (68%) were barriers to implementation. Many did not know their employers' knowledge or attitudes about CAMBRA and its implementation, as evidenced by a "don't know" response range of 29 to 48% for the 4 relevant statements. Respondents' comments included both successes and barriers implementing CAMBRA. CAMBRA protocol has not been widely implemented in private practice, although the current data do not indicate insurmountable barriers. Broader dissemination may be feasible if dental hygienists would obtain more comprehensive knowledge of evidence-based risk assessment protocols and would assume a leadership role in implementing CAMBRA protocols and procedures in private dental practices.

Nicaragua's HIV epidemic is concentrated among men who have sex with men. Nevertheless, the increasing number of HIV cases among heterosexuals, high levels of poverty and migration rates, and incomplete epidemiological data suggest the need to improve the understanding of the epidemic. To examine the prevalence of HIV-related knowledge, attitudes, and sexual risk-taking behaviors, and their predictors among the adult population. A community-based cross-sectional survey was conducted in 2009 among 520 participants ages 15-49 from an ongoing Health and Demographic Surveillance System in Nicaragua. Bivariate analysis and adjusted prevalence ratios were use to examine factors associated with HIV-related knowledge, attitudes, and sexual behavior. Contributing factors for risk-taking behaviors included cognitive, psychosocial, and emotional elements. Insufficient knowledge affecting the accurate assessment of HIV risk were low educational level, poverty, and rural origin, especially among females. Recognizing risk was not sufficient to promote safer sex: 90% of the females and 70% of the males who reported being sexually active in the past year did not use condoms during their last sexual encounter. Inconsistent condom use among men was associated with older age, long-term relationships, and lack of awareness about acquiring HIV infection. Interventions to reduce social-structural contextual factors in Nicaragua are needed so that individuals may adopt and maintain HIV risk reduction strategies. Increased gender-specific HIV education and skills-building programs need to be implemented. Sensitive mass media messages may also increase the knowledge of HIV and AIDS, and serve to encourage protective attitudes and behaviors. Copyright © 2012 Elsevier B.V. All rights reserved.

Children-at-risk for poor nutrition: expanding the approach of future professionals in educational institutions.

Shor, Ron

2011-08-01

To examine how the subject of nutrition is being addressed in the work with children at risk of poor nutrition in educational institutions and what the barriers are which may hinder inclusion of this subject. A structured questionnaire was constructed for the purpose of this study and was implemented with 111 students in Israel who are working in their internships in educational institutions with children who are exposed to risk factors of poor nutrition (e.g., parental neglect, lack of knowledge, poverty). Participants attributed a high level of importance to integrating nutrition-related components in their work. However, the findings indicate less emphasis on nutrition-related components than on psycho-social-educational components, as well as a low level of collaboration with specialists in the area of nutrition. In addition, it was found that knowledge-based barriers and institutional-related systemic barriers may hinder future teachers' capabilities to incorporate those components despite their favorable approach towards this subject. The findings illuminate the need to reduce barriers hampering the individual work with children at risk of poor nutrition in educational institutions. In the training of future teachers, there is a need to advance a bio-psycho-social educational approach incorporating a knowledge base about assessing situations of poor nutrition, including how to advance an interdisciplinary collaboration with specialists in the area of nutrition.

To assess factors associated with a low risk perception of zoonoses and to identify the gaps in knowledge about transmission and prevention of zoonoses in immigrant and Italian workers. A cross-sectional study with 175 workers in the agro-livestock and agro-food industry in Piemonte, Italy, was carried out. Data were collected with a semi-structured questionnaire based on knowledge, attitudes and practices (KAP) survey. We calculated proportions and used chi-square tests and odds ratios to assess associations. Eight individual interviews with key informants on immigration and public health in Piemonte were carried out. Participants were 82 (47%) Italians and 93 (53%) immigrants. Immigrants were from Romania, Morocco, Albania, India, China, Argentina, Peru, Macedonia, Ivory Coast, Ukraine and Colombia. The study revealed significant differences in risk perception at work (p = 0.001). We found associations between "not having correct knowledge about zoonoses" and the following variables: i. "being immigrant" OR = 4.1 (95%CI 1.7;9.8 p ≤ 0.01); ii. "working in the livestock industry" OR = 2.9 (95%CI 1.2;15.4 p = 0.01); and iii. "being an unqualified worker" OR = 4.4 (95%CI 2.9;15.4 p ≤ 0.01). Another strong association was found between being immigrant and having a low job qualification OR = 6.7 (IC95% 2.9 - 15.4 p ≤ 0.01). Asian immigrants were the group with the highest frequency of risky behaviours and the lowest level of knowledge about zoonoses. Our results indicate that there were differences in risk perception of zoonoses between the groups participating in our study. These results suggest that immigrant status can be considered a risk factor for having lower risk perception and lower level of knowledge of zoonoses at work. There is a relationship between this specific knowledge of zoonoses and lack of training and instruction among migrant populations. Our results stress the need for developing education programs on zoonoses prevention among the immigrant population in Piemonte, Italy.

Combining PubMed knowledge and EHR data to develop a weighted bayesian network for pancreatic cancer prediction.

PubMed

Zhao, Di; Weng, Chunhua

2011-10-01

In this paper, we propose a novel method that combines PubMed knowledge and Electronic Health Records to develop a weighted Bayesian Network Inference (BNI) model for pancreatic cancer prediction. We selected 20 common risk factors associated with pancreatic cancer and used PubMed knowledge to weigh the risk factors. A keyword-based algorithm was developed to extract and classify PubMed abstracts into three categories that represented positive, negative, or neutral associations between each risk factor and pancreatic cancer. Then we designed a weighted BNI model by adding the normalized weights into a conventional BNI model. We used this model to extract the EHR values for patients with or without pancreatic cancer, which then enabled us to calculate the prior probabilities for the 20 risk factors in the BNI. The software iDiagnosis was designed to use this weighted BNI model for predicting pancreatic cancer. In an evaluation using a case-control dataset, the weighted BNI model significantly outperformed the conventional BNI and two other classifiers (k-Nearest Neighbor and Support Vector Machine). We conclude that the weighted BNI using PubMed knowledge and EHR data shows remarkable accuracy improvement over existing representative methods for pancreatic cancer prediction.

Farmworkers face a variety of risk factors for eye injuries. Measures of eye protection use and of eye safety knowledge and beliefs are based on a survey of 300 Latino farmworkers in North Carolina. Few farmworkers report using eye protection (8.3%); most (92.3%) report that employers do not provide eye protection. Approximately 70% report that they are not trained in preventing eye injuries; 81% believe that their chances of getting an eye injury are low. Many farmworkers choose to take risks in order to save time. Interventions are needed that target farmworker knowledge and beliefs about eye safety. PMID:21462026

Microplastics in the environment: What can we learn from a decade of engineered nanoparticle fate and risk assessment?

NASA Astrophysics Data System (ADS)

Hüffer, T.; Praetorius, A.; Wagner, S.; von der Kammer, F.; Hofmann, T.

2016-12-01

The field of environmental fate and risk assessment is frequently dominated by "hot topics" of emerging contaminants; in recent years for example pharmaceuticals, nanomaterials or, most recently, microplastics. Since no emerging pollutant is entirely new, a careful assessment of existing knowledge on related substances can help us direct our research efforts and employ the limited resources in a more efficient way. Crucial questions on the environmental implications of microplastics, for example the need for analytical tools, adequate protocols to study their fate, or the effects of aging and a risk assessment based thereon remain largely unanswered. Over the last decade, the field of environmental implications of engineered nanoparticles (ENPs) has been facing similar challenges. The goal of this contribution is to suggest a road-map to pursue the risk assessment of microplastics based on our experience in one decade in ENPs research. We highlight how to avoid potential dead-ends in microplastics research. We also illustrate that cross-linking other research fields, especially polymer chemistry and material sciences, may facilitate filling the urgent knowledge gaps.

2016-01-01

Work-related musculoskeletal disorders (WMSDs) related to computer work have become a serious public health concern. Literature revealed a positive association between computer use and WMSDs. The purpose of this evidence-based pilot project was to provide a series of evidence-based educational sessions on ergonomics to office computer workers to enhance the awareness of risk factors of WMSDs. Seventeen office computer workers who work for the National Board of Certification in Occupational Therapy volunteered for this project. Each participant completed a baseline and post-intervention ergonomics questionnaire and attended six educational sessions. The Rapid Office Strain Assessment and an ergonomics questionnaire were used for data collection. The post-intervention data revealed that 89% of participants were able to identify a greater number of risk factors and answer more questions correctly in knowledge tests of the ergonomics questionnaire. Pre- and post-intervention comparisons showed changes in work posture and behaviors (taking rest breaks, participating in exercise, adjusting workstation) of participants. The findings have implications for injury prevention in office settings and suggest that ergonomics education may yield positive knowledge and behavioral changes among computer workers.

To also determine the effects for PCPs in medical clinics participating in the web-based education with poster reminder intervention as compared with those in control clinics regarding: a) index of knowledge of oral cancer risk factors (RiskOC) and b) index of knowledge of oral cancer diagnostic procedures (DiagOC). Six medical clinics were recruited to participate in this study and randomly assigned to an intervention group or a control group. PCPs (physicians, physician assistants, and advanced practice registered nurses) took a pretest; 2 weeks later, they participated in the web-based educational program, including a posttest (intervention group) or took a posttest only (control group). In each clinic, 1 week following completion of the PCPs' posttests, 94 patients were recruited to complete a one-page survey. The intervention clinics were found to be a significant factor for the PCPs to perform patient OCEs, after controlling for significant covariates, that is, age, main reason for clinic visit, OCE for patient in the past year, clinic's mean DiagOC score, and clinic's mean RiskOC score. The intervention also resulted in the PCPs increasing their pretest to posttest RiskOC scores. The use of intervention has the potential to increase PCPs' short-term knowledge and to increase the frequency of PCPs' routine, nonsymptomatic opportunistic OCE on patients. © 2016 American Association of Public Health Dentistry.

Background Knowledge about coronary heart disease (CHD) and its risk factors is an important pre-requisite for an individual to implement behavioral changes leading towards CHD prevention. There is scant data on the status of knowledge about CHD in the general population of Pakistan. The objective of this study was to assess knowledge of CHD in a broad Pakistani population and identify the factors associated with knowledge. Methods Cross sectional study was carried out at four tertiary care hospitals in Pakistan using convenience sampling. Standard questionnaire was used to interview 792 patient attendants (persons accompanying patients). Knowledge was computed as a continuous variable based on correct answers to fifteen questions. Multivariable linear regression was conducted to determine the factors independently associated with knowledge. Results The mean age was 38.1 (±13) years. 27.1% had received no formal education. The median knowledge score was 3.0 out of a possible maximum of 15. Only 14% were able to correctly describe CHD as a condition involving limitation in blood flow to the heart. Majority of respondents could identify only up to two risk factors for CHD. Most commonly identified risk factors were stress (43.4%), dietary fat (39.1%), smoking (31.9%) and lack of exercise (17.4%). About 20% were not able to identify even a single risk factor for CHD. Factors significantly associated with knowledge included age (p = 0.023), income (p < 0.001), education level (p < 0.001), residence (p < 0.001), a family history of CHD (p < 0.001) and a past history of diabetes (p = 0.004). Preventive practices were significantly lacking; 35%, 65.3% and 84.6% had never undergone assessment of blood pressure, glucose or cholesterol respectively. Only a minority felt that they would modify their diet, stop smoking or start exercising if a family member was to develop CHD. Conclusion This is the first study assessing the state of CHD knowledge in a relatively diverse non-patient population in Pakistan. There are striking gaps in knowledge about CHD, its risk factors and symptoms. These translate to inadequate preventive behavior patterns. Educational programs are urgently required to improve the level of understanding of CHD in the Pakistani population. PMID:16309553

To develop and evaluate the efficacy of an online continuing education course for professionals who provide food safety information to high-risk populations. A 2-credit graduate-level class was converted into six web-based modules (overview of foodborne illness, immunology, pregnancy, human immunodeficiency virus, cancer and transplants, and lifecycle) and offered to nutrition and health professionals. Participants had 8 weeks to complete the modules, pre and post questionnaires, and course evaluation. Those who successfully completed the protocol received six continuing education units from one of three professional associations. Change in knowledge was measured using pre and post questionnaires. Course efficacy was evaluated using a post-course questionnaire. A convenience sample of 140 registered dietitians/dietetic technicians registered, nurses, and extension educators were recruited through professional conferences and electronic mailing lists to take the course. Analysis of variance was used to evaluate differences in knowledge scores for all groups across five main effects (attempt, module, profession, age, and education). Course evaluation responses were used to assess course effectiveness. For each module, knowledge scores increased significantly (P<0.001) from pre to post questionnaire. Overall, knowledge scores increased from 67.3% before the modules to 91.9% afterwards. Course evaluation responses were favorable, and participants indicated that course objectives were met. Online continuing education courses, such as "Food Safety Issues for High Risk Populations," seem to be a convenient, effective option for dietetics professionals, nurses, and extension educators seeking knowledge about food safety issues of high-risk populations. Online learning is a promising delivery approach for the continuing education of health professionals.

An estimated 200,000 children born in Thailand each year are at risk of prenatal exposure to pesticides and associated neurodevelopmental outcomes because of their mothers’ agricultural occupations. Children born to non-agricultural workers may also be at risk of exposure from other pathways of maternal pesticide exposure, including exposure through home use, diet, and other environmental media. Pesticide exposure in Thailand has been linked to unsafe practices and beliefs about pesticides. However, limited information exists on pesticide knowledge, attitudes, and practices among pregnant women in Thailand or elsewhere. Obtaining this information is essential to understand the factors associated with prenatal pesticide exposure, identify populations potentially at risk, and ultimately protect pregnant women and their children. We administered surveys to 76 pregnant women in northern Thailand and used multivariable logistic regression to evaluate associations among pesticide-related knowledge, pregnancy trimester, and pesticide use behavior. In this pilot study, lower knowledge score and earliest trimester of pregnancy were marginally (p < 0.1) associated with unsafe practices in the home, but not at work. Women who worked in agriculture or applied pesticides before becoming pregnant, or who had a previous child were significantly (p < 0.05) more likely to engage in unsafe behaviors in the home during their current pregnancy. We preliminarily conclude that increasing pesticide-related knowledge among pregnant women may help promote safe practices and reduce prenatal exposure. Knowledge-based interventions may be most effective when implemented early in pregnancy and targeted to agricultural workers and other sub-populations at risk of pesticide exposure. PMID:23202693

To understand the role of knowledge as a promoter of hepatitis C virus (HCV) screening among primary care physicians (PCP). A 45-item online questionnaire assessing knowledge of HCV natural history, risk factors, and treatment was distributed to 163 PCP. Logistic regression, adjusted for survey responses, assessed associations between PCP knowledge of HCV natural history and treatment and birth cohort ( i.e ., birth between 1945 and 1965) screening. Response stratification and weighting were used to account for nonresponse and to permit extension of responses to the entire survey population. Associations between various predictors including demographic characteristics, level of training, and HCV treatment experience and HCV knowledge were assessed. Ninety-one individuals (55.8%) responded. Abnormal liver enzymes (49.4%), assessment of HCV-related risk factors (30.6%), and birth cohort membership (20%) were the leading HCV screening indications. Most PCP (64.7%) felt that the combination of risk-factor and birth cohort screening utilizing a self-administered survey while awaiting the physician (55.3%) were the most efficient screening practices. Implementation of birth cohort screening was associated with awareness of the recommendations ( P -value = 0.01), knowledge of HCV natural history ( P -value < 0.01), and prior management of HCV patients ( P -value < 0.01). PCP with knowledge of HCV treatment was also knowledgeable about HCV natural history ( P -value < 0.01). Similarly, awareness of age-based screening recommendations was associated with HCV treatment knowledge ( P -value = 0.03). Comprehensive knowledge of HCV is critical to motivate HCV screening. PCP-targeted educational interventions are required to expand the HCV workforce and linkage-to-care opportunities as we seek global HCV eradication.

To compare family physicians' glaucoma knowledge and clinical skills with ophthalmologists' expectations. An electronic cross-sectional survey of family physicians and ophthalmologists. Participants included members of the Canadian Ophthalmological Society, Canadian Glaucoma Society, and the American Glaucoma Society, as well as family physicians in the Canadian Medical Directory and the Society of Rural Physicians of Canada listserv. Two complementary surveys were developed to evaluate family physicians' glaucoma knowledge and basic examination skills, and ophthalmologists' expected level of family physician clinical knowledge and skills. χ(2) tests identified differences between family physician and ophthalmologist responses. Differences in family physician knowledge based on practice location and frequency of patient visits with a diagnosis of glaucoma were also evaluated. A total of 142 ophthalmologists and 110 family physicians completed the survey. The majority (82%) of family physicians reported seeing patients with diagnosed glaucoma weekly, monthly, or semiannually. Significantly fewer family physicians than expected (p < 0.001) identified African descent (46%) and corticosteroid use (84%) as glaucoma risk factors. Family physicians were significantly less likely to refer based on risk factors (72%) than expected by ophthalmologists (91%; p < 0.001). Only 28% of family physicians were comfortable performing direct ophthalmoscopy, and 37% were comfortable checking for a relative afferent pupillary defect. A significant percentage of family physicians lacked knowledge of glaucoma medications (30%) and side effects (57%). This study revealed significant disparities in family physician glaucoma knowledge, clinical examination skills, and referral practices. Educational materials should target these knowledge gaps.

Pregnant women and their newborns have an increased risk of developing severe influenza and influenza-related complications. In Germany, seasonal influenza vaccination is recommended for pregnant women since 2010. However, little is known about pregnant women's vaccination-related knowledge and attitudes, as well as their risk perceptions. This study therefore assessed pregnant women's vaccination-related knowledge, risk perceptions related to influenza disease and influenza vaccination during pregnancy, and aimed to identify determinants of influenza vaccination uptake during pregnancy in Germany. Between 2012 and 2014, a nationwide web-based prospective cohort study with follow-up interviews was conducted in initially pregnant women who gave birth over the study period. Control groups were set up in a cross-sectional fashion during the follow-up interviews. Women who participated in both, the baseline interview before giving birth and in the 1st interview after giving birth were included in the analysis. Univariate and multiple logistic regression were used to identify associations between influenza vaccination uptake and sociodemographic characteristics as well as items assessing attitude and knowledge. In total, 838 women were included in the analyses. Pregnant women had a positive attitude towards vaccination in general, but only modest vaccination knowledge. Overall, 10.9 % of women were vaccinated against seasonal influenza during pregnancy. While pregnant women perceived classical childhood diseases to be more risky than the respective vaccinations, this relation reversed for influenza: The risk of vaccination was perceived higher than the risk of the disease. These two types of risk perceptions independently determined influenza vaccination uptake-higher perception of disease risk and lower perceptions of vaccination-related risks increased uptake. Additionally, knowledge about the vaccination recommendation for pregnant women and a positive gynaecologist's attitude towards vaccination during pregnancy influenced the uptake significantly. Influenza vaccination uptake in pregnant women is low in Germany. Tailored communication strategies for pregnant women should focus especially on changing the perceptions of personal risks regarding influenza and influenza vaccination during pregnancy. Gynaecologists should be made aware about their crucial role in supporting vaccination decision-making of pregnant women and the need to provide relevant information to counteract misconceptions.

Towards an Obesity-Cancer Knowledge Base: Biomedical Entity Identification and Relation Detection

Obesity is associated with increased risks of various types of cancer, as well as a wide range of other chronic diseases. On the other hand, access to health information activates patient participation, and improve their health outcomes. However, existing online information on obesity and its relationship to cancer is heterogeneous ranging from pre-clinical models and case studies to mere hypothesis-based scientific arguments. A formal knowledge representation (i.e., a semantic knowledge base) would help better organizing and delivering quality health information related to obesity and cancer that consumers need. Nevertheless, current ontologies describing obesity, cancer and related entities are not designed to guide automatic knowledge base construction from heterogeneous information sources. Thus, in this paper, we present methods for named-entity recognition (NER) to extract biomedical entities from scholarly articles and for detecting if two biomedical entities are related, with the long term goal of building a obesity-cancer knowledge base. We leverage both linguistic and statistical approaches in the NER task, which supersedes the state-of-the-art results. Further, based on statistical features extracted from the sentences, our method for relation detection obtains an accuracy of 99.3% and a f-measure of 0.993. PMID:28503356

Evaluating Risk Communication After the Fukushima Disaster Based on Nudge Theory.

Murakami, Michio; Tsubokura, Masaharu

2017-03-01

Using nudge theory and some examples of risk communication that followed the Fukushima disaster, this article discusses the influences and justifications of risk communication, in addition to how risk communication systems are designed. To assist people in making decisions based on their own value systems, we provide three suggestions, keeping in mind that people can be influenced (ie, "nudged") depending on how risk communication takes place: (1) accumulate knowledge on the process of evaluating how the method of risk communication and a system's default design could impact people; (2) clarify the purpose and outcomes of risk communication; and (3) see what risk communication might be ethically unjustifiable. Quantitative studies on risk communication and collective narratives will provide some ideas for how to design better risk communication systems and to help people make decisions. Furthermore, we have shown examples of unjustifiable risk communication.

The epidemiology of injury in bungee jumping, BASE jumping, and skydiving.

PubMed

Søreide, Kjetil

2012-01-01

Knowledge regarding epidemiology of injury is of benefit to injury prevention of activities associated with high risk. As relatively 'young' activities, the investigation of injuries and deaths related in extreme sports such as bungee jumping and BASE jumping is relatively sparse. Studies evaluating risk in civilian and military skydiving activities have been reported over the past decades, but technique and equipment has changed. Risk with bungee jumping is only sporadically reported in the literature, most often in connection with eye injuries, but also rare events of serious, life-threatening injuries and even death. BASE is an acronym for Building, Antenna, Span, Earth, which represents the fixed objects from which jumps are made. Estimated risk in BASE jumping for any injury (independent of severity grade) is 0.4-0.5%, which as 5- to 8-fold higher than skydiving. Typically, men outnumber women in a ratio of 10:1 in both injuries and case fatality rates. Age is frequently reported to range from 30 to 40 years. Notably, differences in training and environmental locations exist between recreational skydiving and BASE jumping. As BASE jumps are made from lower altitudes than skydives, jumpers generally fall at lower speeds, have far less aerodynamic control, and may lose flying stability. Yet, typical injuries include a bruised or sprained ankle during landing. Protective gear including helmet and pads may help to prevent such injuries, while more complex knowledge of human factors, environment and training are needed to prevent fatal injuries.

2011-01-01

This longitudinal study focused on the effects of two different principles of intervention in children at risk of developing dyslexia from 5 to 8 years old. The children were selected on the basis of a background questionnaire given to parents and preschool teachers, with cognitive and functional magnetic resonance imaging results substantiating group differences in neuropsychological processes associated with phonology, orthography, and phoneme-grapheme correspondence (i.e., alphabetic principle). The two principles of intervention were bottom-up (BU), "from sound to meaning", and top-down (TD), "from meaning to sound." Thus, four subgroups were established: risk/BU, risk/TD, control/BU, and control/TD. Computer-based training took place for 2 months every spring, and cognitive assessments were performed each fall of the project period. Measures of preliteracy skills for reading and spelling were phonological awareness, working memory, verbal learning, and letter knowledge. Literacy skills were assessed by word reading and spelling. At project end the control group scored significantly above age norm, whereas the risk group scored within the norm. In the at-risk group, training based on the BU principle had the strongest effects on phonological awareness and working memory scores, whereas training based on the TD principle had the strongest effects on verbal learning, letter knowledge, and literacy scores. It was concluded that appropriate, specific, data-based intervention starting in preschool can mitigate literacy impairment and that interventions should contain BU training for preliteracy skills and TD training for literacy training.

Our goal is to create an ontology that will allow data integration and reasoning with subject data to classify subjects, and based on this classification, to infer new knowledge on Autism Spectrum Disorder (ASD) and related neurodevelopmental disorders (NDD). We take a first step toward this goal by extending an existing autism ontology to allow automatic inference of ASD phenotypes and Diagnostic & Statistical Manual of Mental Disorders (DSM) criteria based on subjects' Autism Diagnostic Interview-Revised (ADI-R) assessment data. Knowledge regarding diagnostic instruments, ASD phenotypes and risk factors was added to augment an existing autism ontology via Ontology Web Language class definitions and semantic web rules. We developed a custom Protégé plugin for enumerating combinatorial OWL axioms to support the many-to-many relations of ADI-R items to diagnostic categories in the DSM. We utilized a reasoner to infer whether 2642 subjects, whose data was obtained from the Simons Foundation Autism Research Initiative, meet DSM-IV-TR (DSM-IV) and DSM-5 diagnostic criteria based on their ADI-R data. We extended the ontology by adding 443 classes and 632 rules that represent phenotypes, along with their synonyms, environmental risk factors, and frequency of comorbidities. Applying the rules on the data set showed that the method produced accurate results: the true positive and true negative rates for inferring autistic disorder diagnosis according to DSM-IV criteria were 1 and 0.065, respectively; the true positive rate for inferring ASD based on DSM-5 criteria was 0.94. The ontology allows automatic inference of subjects' disease phenotypes and diagnosis with high accuracy. The ontology may benefit future studies by serving as a knowledge base for ASD. In addition, by adding knowledge of related NDDs, commonalities and differences in manifestations and risk factors could be automatically inferred, contributing to the understanding of ASD pathophysiology.

Critical knowledge gaps seriously hinder disaster risk reduction and resilience building efforts, especially in disaster prone least developing countries. The information scarcity is highest at local levels, in terms of the spatial information of risk, resources and capacities of communities. We propose a general procedure that combines community-based participatory mapping processes, which has been widely used by in various government and non-government organization projects in the fields of natural resources management, disaster risk reduction and rural development, and the emerging collaborative digital mapping techniques to tackle this challenge. We demonstrate the value and potential of this general participatory and collaborative digital mapping by conducting a pilot study in the flood prone lower Karnali River basin in Western Nepal. We engaged a range of stakeholders to generate geographic information on resources, capacities and flood risks of pilot communities according to local needs. The new digital community maps are richer in contents, more accurate, and easier to update and share than those produced using conventional Vulnerability and Capacity Assessments (VCAs), a variant of Participatory Rural Appraisal (PRA) that is widely used by in various government and non-government organizations. This approach, as an inclusive form of risk knowledge co-generation, can play a critical role in improving evidence-based understanding of disaster risk and enhance disaster resilience worldwide.

. Many healthy women consider genetic testing for breast cancer risk, yet BRCA testing issues are complex. . To determine whether an intelligent tutor, BRCA Gist, grounded in fuzzy-trace theory (FTT), increases gist comprehension and knowledge about genetic testing for breast cancer risk, improving decision making. . In 2 experiments, 410 healthy undergraduate women were randomly assigned to 1 of 3 groups: an online module using a Web-based tutoring system (BRCA Gist) that uses artificial intelligence technology, a second group read highly similar content from the National Cancer Institute (NCI) Web site, and a third that completed an unrelated tutorial. . BRCA Gist applied FTT and was designed to help participants develop gist comprehension of topics relevant to decisions about BRCA genetic testing, including how breast cancer spreads, inherited genetic mutations, and base rates. . We measured content knowledge, gist comprehension of decision-relevant information, interest in testing, and genetic risk and testing judgments. . Control knowledge scores ranged from 54% to 56%, NCI improved significantly to 65% and 70%, and BRCA Gist improved significantly more to 75% and 77%, P < 0.0001. BRCA Gist scored higher on gist comprehension than NCI and control, P < 0.0001. Control genetic risk-assessment mean was 48% correct; BRCA Gist (61%) and NCI (56%) were significantly higher, P < 0.0001. BRCA Gist participants recommended less testing for women without risk factors (not good candidates; 24% and 19%) than controls (50%, both experiments) and NCI (32%), experiment 2, P < 0.0001. BRCA Gist testing interest was lower than in controls, P < 0.0001. . BRCA Gist has not been tested with older women from diverse groups. . Intelligent tutors, such as BRCA Gist, are scalable, cost-effective ways of helping people understand complex issues, improving decision making. © The Author(s) 2014.

Knowledge of psychosocial characteristics that helps to identify patients at increased risk for readmission for heart failure (HF) may facilitate timely and targeted care. We hypothesized that certain psychosocial characteristics extracted from the electronic health record (EHR) would be associated with an increased risk for hospital readmission within the next 30 days. We identified 15 psychosocial predictors of readmission. Eleven of these were extracted from the EHR (six from structured data sources and five from unstructured clinical notes). We then analyzed their association with the likelihood of hospital readmission within the next 30 days among 729 patients admitted for HF. Finally, we developed a multivariable predictive model to recognize individuals at high risk for readmission. We found five characteristics-dementia, depression, adherence, declining/refusal of services, and missed clinical appointments-that were associated with an increased risk for hospital readmission: the first four features were captured from unstructured clinical notes, while the last item was captured from a structured data source. Unstructured clinical notes contain important knowledge on the relationship between psychosocial risk factors and an increased risk of readmission for HF that would otherwise have been missed if only structured data were considered. Gathering this EHR-based knowledge can be automated, thus enabling timely and targeted care. Copyright © 2011 The Academy of Psychosomatic Medicine. Published by Elsevier Inc. All rights reserved.

HIV-related stigma has been shown to impede HIV-antibody testing and safer sexual practices in adults. Less is known about its effects on prevention programs among at-risk youth. This study examined the longitudinal relationships between HIV-stigma and HIV-knowledge following completion of a validated group-based intervention. Data were provided by 1,654 African-American adolescents who participated in a large multi-city prevention trial (Project iMPACCS). Participants were randomly assigned to an empirically-validated skill-based intervention or a general health promotion control group. Both stigma and knowledge were assessed at baseline and post-intervention. Results suggested that adolescents participating in the intervention showed improvements in knowledge and decreases in stigma when compared to controls. Improvements in stigma appeared to be partly driven by improvements in knowledge. Higher baseline stigma was shown to reduce gains in knowledge in both the treatment and control groups. Results suggest that HIV-stigma can interfere with how youth identify with and internalize messages from group-based prevention trials.

Obesity prevention in pediatrics: A pilot pediatric resident curriculum intervention on nutrition and obesity education and counseling.

Obesity is a highly burdensome public health issue associated with premature death, multiple comorbid disabilities and staggering healthcare costs. Between 1980-2000, the prevalence of obesity among children and adolescents nearly tripled. Obesity subjects youth to social stigmatization and discrimination. These economic and personal burdens mandate targeted prevention and detection educational programs for all individuals at risk. The most cost-effective method of approaching this obesity epidemic is through education of health professionals. As part of an "Obesity Prevention in Pediatrics" curriculum, postgraduate-year (PGY)-2 residents first observed and then participated in the dietary evaluation and counseling of pediatric patients and their families. Attitudinal questionnaires, multiple-choice knowledge examinations and a pre-established checklist of desired skills and behaviors provided evaluation of the curriculum's effect on the participants' ability and willingness to manage actually obese or at-risk pediatric patients and their families. Attitudinal survey and knowledge test scores from control PGY-3 residents generally confirmed that their knowledge and counseling skills on obesity prevention and management were well below expectation. Following participation in the curriculum, study residents' knowledge tended to improve, as did their level of comfort in counseling obese and at-risk children, adolescents and their parents. Implementation of an "Obesity Prevention in Pediatrics" curriculum appears to improve participants' knowledge base as well as their skills and level of personal comfort in the recognition, evaluation and management, including counseling, of both obese and at-risk pediatric patients and their families.

Sexual knowledge and victimization in adults with autism spectrum disorders.

2014-09-01

There is a significant gap in understanding the risk of sexual victimization in individuals with autism spectrum disorders (ASD) and the variables that contribute to risk. Age appropriate sexual interest, limited sexual knowledge and experiences, and social deficits, may place adults with ASD at increased risk. Ninety-five adults with ASD and 117 adults without ASD completed questionnaires regarding sexual knowledge sources, actual knowledge, perceived knowledge, and sexual victimization. Individuals with ASD obtained less of their sexual knowledge from social sources, more sexual knowledge from non-social sources, had less perceived and actual knowledge, and experienced more sexual victimization than controls. The increased risk of victimization by individuals with ASD was partially mediated by their actual knowledge. The link between knowledge and victimization has important clinical implications for interventions.

To describe the level of knowledge regarding risk factors and warning signs for stroke and heart attack among White and African American adults in Michigan and to quantify racial disparities. Knowledge of stroke and heart attack risk factors and warning signs was assessed by using data from the 2004 Michigan Behavioral Risk Factor Survey. Prevalence estimates of knowledge were generated, and statistical differences in knowledge between Whites and African Americans were assessed. Adequate knowledge was defined as knowing 3 correct warning signs or risk factors. Logistic regression models were used to quantify the racial disparity in knowledge while controlling for potential confounding. Whites had substantially higher levels of adequate knowledge of risk factors (stroke: 31.6% vs 13.8%; heart attack: 52.6% vs 24.3%) and warning signs (stroke: 30.0% vs 17.2%; heart attack: 29.3% vs 13.8%) compared with African Americans (all observed differences were significant at P < .05). The odds of adequate knowledge of risk factors (stroke: adjusted odds ratio [AOR] 2.9; heart attack: AOR 3.4) and warning signs (stroke: AOR 2.0; heart attack: AOR 2.4) were significantly higher for Whites than for African Americans. A strong racial disparity in the knowledge of stroke and heart attack risk factors and warning signs exists among Michigan adults. Communitywide public education programs in conjunction with targeted interventions for at-risk populations are necessary to produce meaningful improvements in the awareness of stroke and heart attack risk factors and warning signs among Michigan adults.

Cross-sectional survey. Multifactorial risk factor screening and treatment is needed for subsequent falls/osteoporotic fractures prevention (SFOFP), given the elevated risk among patients with distal radius fracture (DRF). The primary objective was to describe hand therapists' knowledge and clinical practice patterns for assessment, treatment, referral, and education with respect to SFOFP for patients with DRF older than 45 years. Secondary objective was to explore therapist's preferences in content and delivery of knowledge translation tools that would support implementation of SFOFP. A cross-sectional multinational (Canada, the United States, and India) survey was conducted among 272 therapists from August to October 2014. Completed surveys were analyzed descriptively. Surveys were completed by 157 therapists. Most respondents were from the United States (59%), certified hand therapists (54%), and females (87%). Although 65%-90% believed that they had knowledge about SFOFP assessment, treatment, and referral options, 55% did not include it in their routine practice for patients with DRF. Most assessed medication history (82%) and never used a Fracture Risk Assessment Tool (90%) or lower extremity muscle strength testing (54%) to identify those at risk of secondary fractures. With respect to treatment, approximately 33% always used upper extremity muscle strengthening exercises. Most reported rarely (sometimes to never) using balance (79%), lower extremity muscle strengthening (85%), bone strengthening (54%), or community-based physical activity (72%) programs. Similarly, when surveyed about patient education, therapists rarely (sometimes to never) advised patients about web-based resources (94%), regular vision testing (92%), diet for good bone health (87%), bone density evaluation (86%), footwear correction (73%), and hazard identification (67%). Most hand therapists were interested to receive more information on SFOFP for patients with DRF. Nearly one-half preferred to have Web sites for patients, and two-fifth were in favor of pamphlets for patients. Current practice patterns reveal care gaps and limited implementation with respect to SFOFP for patients with DRF. Future research should focus on web-based educational/knowledge translation strategies to promote implementation of multifactorial fall risk screening and hand therapist's engagement in SFOFP for patients with DRF.

School nurses perform a crucial role in the prevention, identification, intervention, and reporting of child maltreatment. The purpose of this article is to share the highlights of a research project conducted to (a) examine the effectiveness of an educational intervention program in increasing the knowledge, confidence, and self-efficacy in school nurses regarding children at risk of maltreatment; and (b) discover issues surrounding the comfort level engaging with children, communicating with teachers and other personnel, and ethical issues. The study consisted of two phases. Phase 1 was a face-to-face evidenced-based educational intervention. Focus groups implemented in Phase 2 discovered specific concerns of school nurses. Results indicate a significant increase in school nurse knowledge, confidence, and self-efficacy related to children at risk. Five themes were identified from the focus groups: the importance of interprofessional collaboration, identifiers of children at risk of maltreatment, the role of the school nurse as a mentor and leader, the importance of advancing one's knowledge and skill set, and constraints faced by school nurses.

HIV Knowledge, Risk Behavior, Stigma, and Their Impact on HIV Testing among Asian American and Pacific Islanders: A Review of Literature.

2017-01-02

Asian American and Pacific Islanders (AAPIs) are the fastest growing population in the United States with documented increases in HIV rates. AAPIs are as likely as other racial/ethnic groups to engage in HIV-related risk behaviors, while being concomitantly less likely to have been HIV tested. Testing is a critical step in HIV prevention. Research points to various barriers to HIV-related testing including HIV knowledge and attitude and stigma. However, these factors and their impact among AAPIs are poorly understood. Myths about this population's "model minority" status compound AAPIs' sociocultural factors including English language proficiency, access to healthcare, and a culture of "silence" that negatively influences HIV-related research. In this article, the authors review the scientific literature on knowledge, risk behavior, and stigma to document the current state of research. Based on the review the authors offer a set of research, policy, and practice recommendations for social workers and other service providers working with AAPIs.

Investigate workers' knowledge and beliefs about cardiometabolic risk. A survey on the risks of diabetes, cardiovascular disease, and chronic kidney disease was disseminated among Dutch construction workers and employees from the general working population. We had 482 respondents (26.8%) among construction workers and 738 respondents (65.1%) among the general working population. Employees showed reasonable basic knowledge, especially about cardiovascular disease risk factors and risk reduction. Nevertheless, they also had knowledge gaps (eg, specific dietary intake) and showed misconceptions of what elevated risk entails. Employees having lower education, being male, and having lower health literacy demonstrated less adequate knowledge and beliefs. To improve the potential effect of health risk assessments in the occupational setting, physicians should explain what it means to be at elevated cardiometabolic risk and target their messages to employee subgroups.

A risk-based inspection system and a piping inspection guideline model were developed in this study. The research procedure consists of two parts--the building of a risk-based inspection model for piping and the construction of a risk-based piping inspection guideline model. Field visits at the plant were conducted to develop the risk-based inspection and strategic analysis system. A knowledge-based model had been built in accordance with international standards and local government regulations, and the rational unified process was applied for reducing the discrepancy in the development of the models. The models had been designed to analyze damage factors, damage models, and potential damage positions of piping in the petrochemical plants. The purpose of this study was to provide inspection-related personnel with the optimal planning tools for piping inspections, hence, to enable effective predictions of potential piping risks and to enhance the better degree of safety in plant operations that the petrochemical industries can be expected to achieve. A risk analysis was conducted on the piping system of a petrochemical plant. The outcome indicated that most of the risks resulted from a small number of pipelines.

Orphans and vulnerable youth who live in group homes are at risk of poor mental health and sexual and drug-using behaviors that increase the risk of HIV transmission. This study explores factors related to this risk among youth living in group homes ("children's homes") for orphans and vulnerable children in South Africa, a country afflicted by high levels of parental loss due to HIV. The study explores 1) knowledge and attitudes about HIV, 2) social support, 3) communication with group home caregivers, and 4) the relevance of an existing evidence-based HIV prevention and mental health promotion program to situations where sexual and drug risk behaviors can occur. In-depth qualitative individual interviews were conducted with 20 youth (age 10 to 16 years) residing in two children's homes in Durban, South Africa. Content analysis focused on critical themes related to coping and prevention of risk activities. Respondents exhibited inconsistent and incomplete knowledge of HIV transmission and prevention. They displayed positive attitudes toward people living with HIV, but reported experiencing or witnessing HIV-related stigma. Participants witnessed substance use and romantic/sexual relationships among their peers; few admitted to their own involvement. While relationships with childcare workers were central to their lives, youth reported communication barriers related to substance use, sex, HIV, and personal history (including parental loss, abuse, and other trauma). In conclusion, these qualitative data suggest that evidence-based HIV prevention programs that bring caregivers and youth together to improve communication, HIV knowledge, social support, youth self-esteem, and health care, reduce sexual and drug risk behaviors, and strengthen skills related to negotiating situations of sexual and substance use possibility could benefit youth and childcare workers in children's homes.

Decision making for zoonotic disease management should be based on many forms of appropriate data and sources of evidence. However, the criteria and timing for policy response and the resulting management decisions are often altered when a disease outbreak occurs and captures full media attention. In the case of waterborne disease, such as the robust protozoa, Cryptosporidium spp, exposure can cause significant human health risks and preventing exposure by maintaining high standards of biological and chemical water quality remains a priority for water companies in the UK. Little has been documented on how knowledge and information is translated between the many stakeholders involved in the management of Cryptosporidium, which is surprising given the different drivers that have shaped management decisions. Such information, coupled with the uncertainties that surround these data is essential for improving future management strategies that minimise disease outbreaks. Here, we examine the interplay between scientific information, the media, and emergent government and company policies to examine these issues using qualitative and quantitative data relating to Cryptosporidium management decisions by a water company in the North West of England. Our results show that political and media influences are powerful drivers of management decisions if fuelled by high profile outbreaks. Furthermore, the strength of the scientific evidence is often constrained by uncertainties in the data, and in the way knowledge is translated between policy levels during established risk management procedures. In particular, under or over-estimating risk during risk assessment procedures together with uncertainty regarding risk factors within the wider environment, was found to restrict the knowledge-base for decision-making in Cryptosporidium management. Our findings highlight some key current and future challenges facing the management of such diseases that are widely applicable to other risk management situations. Copyright © 2011 Elsevier Ltd.

What motivates individuals to protect themselves from risks: the case of wildland fires.

PubMed

Martin, Ingrid M; Bender, Holly; Raish, Carol

This research investigates the cognitive perceptual process that homeowners go through when faced with the decision to protect themselves from the risk of wildfires. This decision can be examined by looking at the interaction between the integrated protection motivation theory-transtheoretical model and different levels of homeowners' subjective knowledge related to wildfire risks. We investigated the role of motivation, decision stages of risk readiness, and subjective knowledge on the number of risk-mitigating actions undertaken by homeowners living in high-risk communities. The results indicate that homeowners who are in an early or precontemplative stage (both low and high subjective knowledge) as well as low knowledge contemplatives are motivated by their perceived degree of vulnerability to mitigate the risk. In contrast, high knowledge contemplatives' potential behavioral changes are more likely to be motivated by increasing their perceptions of the severity of the risk. Risk-mitigating behaviors undertaken by high knowledge action homeowners are influenced by their perceptions of risk severity, self-efficacy, and response efficacy. In contrast, the low knowledge action homeowners engage in risk reduction behaviors without the influence of any of the PMT variables; demonstrating their motivation to emulate others in their community. These results have implications for the type of information that should be used to effectively communicate risks in an effort to influence the diverse homeowner segments to engage in risk-reduction behaviors.

Sex knowledge, attitudes, and high-risk sexual behaviors among unmarried youth in Hong Kong

PubMed Central

2013-01-01

Background Little is known about sex knowledge, attitudes, and high-risk sexual behaviors among unmarried youth in Hong Kong. It is of public health importance to investigate this topic to inform sex education, policymaking, and prevention and intervention programs. Methods Based on the Youth Sexuality Survey conducted by Hong Kong Family Planning Association (FPAHK) in 2011, this study explored the characteristics of sexual knowledge, attitudes, and high-risk sexual behaviors among 1,126 unmarried youth aged 18 to 27 years. Multiple logistic regressions were performed to examine factors associated with unmarried youth’s premarital sex, casual relationships, multiple sex partners, and premarital pregnancy. Results Unmarried youth in Hong Kong had adequate sex knowledge, but contraceptive knowledge was deficient. The majority of unmarried youth (63.8%) held liberal attitudes toward premarital sex and about half held liberal attitudes toward any form of sexual activity and premarital pregnancy. Around 60% held conservative attitudes toward causal sex relationships and multiple sex partners. Males tended to hold more liberal attitudes toward high-risk sex behaviors than female youth. Approximately 41.5% of unmarried youth reported having engaged in premarital sex, whereas less than 10% engaged in high-risk sexual behaviors. Males also reported higher amounts of premarital sex, casual sex relationships, and multiple sex partners. Females reported higher levels of sexual coercion. Logistic regressions indicated that being older, coming from a divorced family, out of school status and liberal attitudes toward risky sex behavior were more likely to engage in premarital sex or high-risk sex behaviors, and being female, being better educated and being immigrants were less likely to engage in premarital sex. However, being immigrants was more likely to engage in casual relationship and to have multiple partners. Conclusions Premarital sex is becoming more prevalent among unmarried youth in Hong Kong, and a small proportion of young adults are engaging in high-risk sexual behaviors. Sex education and HIV prevention programs should equip them with adequate knowledge on contraception and condom use. Intervention programs can start with their attitudes toward sex. PMID:23895326

The modern medical treatment of HIV with antiretroviral therapy (ART) has drastically reduced the morbidity and mortality in patients infected with this virus. ART has also been shown to reduce the transmission risk from individual patients as well as the spread of the infection at the population level. This position statement from the Public Health Agency of Sweden and the Swedish Reference Group for Antiviral Therapy is based on a workshop organized in the fall of 2012. It summarizes the latest research and knowledge on the risk of HIV transmission from patients on ART, with a focus on the risk of sexual transmission. The risk of transmission via shared injection equipment among intravenous drug users is also examined, as is the risk of mother-to-child transmission. Based on current knowledge, the risk of transmission through vaginal or anal intercourse involving the use of a condom has been judged to be minimal, provided that the person infected with HIV fulfils the criteria for effective ART. This probably also applies to unprotected intercourse, provided that no other sexually transmitted infections are present, although it is not currently possible to fully support this conclusion with direct scientific evidence. ART is judged to markedly reduce the risk of blood-borne transmission between people who share injection equipment. Finally, the risk of transmission from mother to child is very low, provided that ART is started well in advance of delivery.

Science Goals in Radiation Protection for Exploration

Space radiation presents major challenges to future missions to the Earth s moon or Mars. Health risks of concern include cancer, degenerative and performance risks to the central nervous system, heart and lens, and the acute radiation syndromes. The galactic cosmic rays (GCR) contain high energy and charge (HZE) nuclei, which have been shown to cause qualitatively distinct biological damage compared to terresterial radiation, such as X-rays or gamma-rays, causing risk estimates to be highly uncertain. The biological effects of solar particle events (SPE) are similar to terresterial radiation except for their biological dose-rate modifiers; however the onset and size of SPEs are difficult to predict. The high energies of GCR reduce the effectiveness of shielding, while SPE s can be shielded however the current gap in radiobiological knowledge hinders optimization. Methods used to project risks on Earth must be modified because of the large uncertainties in projecting health risks from space radiation, and thus impact mission requirements and costs. We describe NASA s unique approach to radiation safety that applies probabilistic risk assessments and uncertainty based criteria within the occupational health program for astronauts and to mission design. The two terrestrial criteria of a point estimate of maximum acceptable level of risk and application of the principle of As Low As Reasonably Achievable (ALARA) are supplemented by a third requirement that protects against risk projection uncertainties using the upper 95% confidence level (CL) in radiation risk projection models. Exploration science goals in radiation protection are centered on ground-based research to achieve the necessary biological knowledge, and in the development of new technologies to improve SPE monitoring and optimize shielding. Radiobiology research is centered on a ground based program investigating the radiobiology of high-energy protons and HZE nuclei at the NASA Space Radiation Laboratory (NSRL) located at DoE s Brookhaven National Laboratory in Upton, NY. We describe recent NSRL results that are closing the knowledge gap in HZE radiobiology and improving exploration risk estimates. Linking probabilistic risk assessment to research goals makes it possible to express risk management objectives in terms of quantitative metrics, which include the number of days in space without exceeding a given risk level within well defined confidence limits, and probabilistic assessments of the effectiveness of design trade spaces such as material type, mass, solar cycle, crew selection criteria, and biological countermeasures. New research in SPE alert and risk assessment, individual radiation sensitivity, and biological countermeasure development are described.

Communities are not immune from extreme events or natural disasters that can lead to large-scale consequences for the nation and public. Improving resilience to better prepare, plan, recover, and adapt to disasters is critical to reduce the impacts of extreme events. The National Research Council (NRC) report discusses the topic of how to increase resilience to extreme events through a vision of resilient nation in the year 2030. The report highlights the importance of data, information, gaps and knowledge challenges that needs to be addressed, and suggests every individual to access the risk and vulnerability information to make their communities more resilient. This project presents an intelligent system, Flood AI, for flooding to improve societal preparedness by providing a knowledge engine using voice recognition, artificial intelligence, and natural language processing based on a generalized ontology for disasters with a primary focus on flooding. The knowledge engine utilizes the flood ontology and concepts to connect user input to relevant knowledge discovery channels on flooding by developing a data acquisition and processing framework utilizing environmental observations, forecast models, and knowledge bases. Communication channels of the framework includes web-based systems, agent-based chat bots, smartphone applications, automated web workflows, and smart home devices, opening the knowledge discovery for flooding to many unique use cases.

Rift Valley fever (RVF), a mosquito-borne disease affecting ruminants and humans, is one of the most important viral zoonoses in Africa. The objective of the present study was to develop a geographic knowledge-based method to map the areas suitable for RVF amplification and RVF spread in four East African countries, namely, Kenya, Tanzania, Uganda and Ethiopia, and to assess the predictive accuracy of the model using livestock outbreak data from Kenya and Tanzania. Risk factors and their relative importance regarding RVF amplification and spread were identified from a literature review. A numerical weight was calculated for each risk factor using an analytical hierarchy process. The corresponding geographic data were collected, standardized and combined based on a weighted linear combination to produce maps of the suitability for RVF transmission. The accuracy of the resulting maps was assessed using RVF outbreak locations in livestock reported in Kenya and Tanzania between 1998 and 2012 and the ROC curve analysis. Our results confirmed the capacity of the geographic information system-based multi-criteria evaluation method to synthesize available scientific knowledge and to accurately map (AUC = 0.786; 95% CI [0.730–0.842]) the spatial heterogeneity of RVF suitability in East Africa. This approach provides users with a straightforward and easy update of the maps according to data availability or the further development of scientific knowledge. PMID:27631374

To investigate mothers' knowledge of reducing the risks for sudden infant death syndrome (SIDS) and attitudes towards safer sleep practices. A cross-sectional survey was carried out in deprived areas of Bristol, UK. Recruitment took place in 2014 at local health visitor-led baby clinics. Of 432 mothers approached, 400 (93%) completed the face-to-face survey. Participants with infants at 'higher' risk of SIDS (using an algorithm based on a previous observational study) were compared with those at 'lower' risk. The survey asked participants to recall three SIDS risk reduction strategies (unprompted), and scored responses to 14 SIDS risk-related infant sleep scenarios (prompted). Overall, 48/400 (12%) mothers were classified as higher risk. Mothers in the higher risk group were less likely to breast feed (multivariate OR=3.59(95% CI 1.46 to 8.86)), less likely to be able to cite two or more unprompted correct SIDS risk reduction strategies (multivariate OR=2.05(95% CI 1.02 to 4.13)) and scored lower on prompted safer sleep scenarios overall.Notably, only 206/400 (52%) of all mothers surveyed (33% in the higher risk group) from these deprived areas in Bristol identified infant sleep position as a risk reduction strategy for SIDS, despite 25 years of campaigns. Mothers in the higher risk group were disadvantaged when it came to some aspects of knowledge of SIDS risk reduction and attitudes to safer sleep. The initial 'Back-to Sleep' message that dramatically reduced these deaths a generation ago needs more effective promotion for today's generation of mothers. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Oral cancer is a preventable disease. Its occurrence is mostly due to lifestyle. In Sudan, the use of smokeless tobacco (Toombak) has long been linked to oral cancer. Knowledge of the signs and symptoms of oral cancer may well aid in early diagnosis and treatment. This is bound to result in increasing survival rates, as well as reducing the oral cancer burden on the society. This study aimed to assess oral cancer awareness regarding knowledge of signs, symptoms, risk factors and sources of the information. Furthermore, it attempts to evaluate attitudes towards oral cancer screening and any previous experience of screening, amongst dental patients attending University of Science and Technology (UST) Dental Teaching Hospital. Omdurman, Sudan. A hospital based cross-sectional study, interviewer-administered questionnaire was conducted amongst 500 adult patients attending the UST Dental Hospital during 2015. A total of 57.7% (286) of the individuals demonstrated good knowledge of signs and symptoms, whereas 49% (139) expressed good knowledge of risk factors of oral cancer. For the majority of the individuals 66.1% (290), the most common source of information about oral cancer was from the media, while 33.9% individuals (149), obtained knowledge from direct contact of health workers. The overwhelming majority, 93.2% (466) never screened for oral cancer despite their positive attitude towards it 66.4% (332). Knowledge of risk factors associated significantly with those reported positive attitude towards oral cancer screening and those reported direct contact with health workers as a source of information, (p ≤ 0.001). Moreover, females and those living in urban districts scores higher than their counterpart in knowledge of risk factor of oral cancer. In addition, those employed 58.6% (280) and 62.8% (164) with correct believes about oral cancer showed significant association with positive knowledge of signs and symptoms (p ≤ 0.05). Awareness levels, knowledge of risk factors and identifying early signs and symptoms of oral cancer necessitate the need for more structured preventive programs using media. Dentists and health workers should do more because they have a pivotal role in early diagnosis by performing oral cancer screening, raising levels of knowledge and in rectifying misconceptions about oral cancer. This would entail a reduction in high rates of morbidity and mortality associated with oral cancer.

Background Cardiovascular disease (CVD) is on the rise in low- and middle-income countries (LMIC) and is proving difficult to combat due to the emphasis on improving outcomes in maternal and child health and infectious diseases, against a backdrop of severe human resource and infrastructure constraints. Effective task-sharing from physicians or nurses to community health workers (CHWs) to conduct population-based screening for persons at risk, has the potential to mitigate the impact of CVD on vulnerable populations. CHWs in Bangladesh, Guatemala, Mexico, and South Africa were trained to conduct non-invasive population-based screening for persons at high risk for CVD. Objective (s) The objectives of this study were to quantitatively assess the performance of CHWs during training and to qualitatively capture their training and fieldwork experiences while conducting non-invasive screening for cardiovascular disease (CVD) risk in their communities. Methods Written tests were used to assess CHWs’ acquisition of content knowledge during training, and focus group discussions conducted to capture their training and fieldwork experiences. Results Training was effective at increasing the CHWs’ content knowledge of cardiovascular disease (CVD) and this knowledge was largely retained up to six months after the completion of field work. Common themes which need to be addressed when designing task sharing with CHWs in chronic diseases are identified, including language, respect, and compensation. The importance of having intimate knowledge of the community receiving services from design to implementation is underscored. Conclusions Effective training for screening for CVD in community settings should have a strong didactic core that is supplemented with culture-specific adaptations in the delivery of instruction. The incorporation of expert and intimate knowledge of the communities themselves is critical, from the design to implementation phases of training. Challenges such as role definition, defining career paths, and providing adequate remuneration, must be addressed. PMID:25754566

Written tests were used to assess CHW's acquisition of content knowledge during training, and focus group discussions were conducted to capture their training and fieldwork experiences. Training was effective at increasing the CHW's content knowledge of CVD, and this knowledge was largely retained up to 6 months after the completion of fieldwork. Common themes that need to be addressed when designing task-sharing with CHW in chronic diseases are identified, including language, respect, and compensation. The importance of having intimate knowledge of the community receiving services from design to implementation is underscored. Effective training for screening for CVD in community settings should have a strong didactic core that is supplemented with culture-specific adaptations in the delivery of instruction. The incorporation of expert and intimate knowledge of the communities themselves is critical, from the design to implementation phases of training. Challenges such as role definition, defining career paths, and providing adequate remuneration must be addressed. Copyright © 2015 World Heart Federation (Geneva). Published by Elsevier B.V.

Management of zoonotic disease is necessary if countryside users are to gain benefit rather than suffer harm from their activities, and to avoid disproportionate reaction to novel threats. We introduce a conceptual framework based on the pressure–state–response model with five broad responses to disease incidence. Influencing public behaviour is one response and requires risk communication based on an integration of knowledge about the disease with an understanding of how publics respond to precautionary advice. A second framework emphasizes how risk communication involves more than information provision and should address dimensions including points-of-intervention over time, place and audience. The frameworks are developed by reference to tick-borne Lyme borreliosis (also known as Lyme disease), for which informed precautionary behaviour is particularly relevant. Interventions to influence behaviour can be directed by knowledge of spatial and temporal variation of tick abundance, what constitutes risky behaviour, how people respond to information of varying content, and an understanding of the social practices related to countryside use. The frameworks clarify the response options and help identify who is responsible for risk communication. These aspects are not consistently understood, and may result in an underestimation of the role of land-based organizations in facilitating appropriate precautionary behaviour. PMID:21624921

After recalling the numerous peace expeditions of the Italian Armed Forces in foreign countries, the author underlines the several health risk factors that such missions imply. The assessment of the biological risk should be based on the knowledge of the local sanitary situation and on the analysis of the operative characteristics of the mission: prevention is based on vaccinations (with plans based on the operative tasks and destinations) and on antimalaric chemoprophylaxis, carried out following WHO indications. In conclusion, the current organization of military field hospitals is briefly described.

Human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) are among the most complex health problems in the world. Young people are at high risk of HIV and AIDS infections and are, therefore, in need of targeted prevention. School-based HIV/AIDS health education may be an effective way to prevent the spread of AIDS among adolescents. The study was a school-based intervention conducted in three middle schools and two high schools in Wuhan, China, which included 702 boys and 766 girls, with ages from 11 to 18 years old. The intervention was a one-class education program about HIV/AIDS for participants. HIV/AIDS knowledge, attitude, and high-risk behaviors were investigated using an anonymous self-administered questionnaire before and after the education intervention. Chi-square test was used to compare differences before and after the intervention. Non-conditional logistic regression analysis was used to identify the factors that affect HIV/AIDS knowledge. Misconceptions about basic medical knowledge and non-transmission modes of HIV/AIDS among all the students prevail. Approximately 10% to 40% of students had negative attitudes about HIV/AIDS before the intervention. After the intervention, all of the students had significant improvements in knowledge and attitude about HIV/AIDS (P<.05), indicating that educational intervention increased the students' knowledge significantly and changed their attitudes positively. Logistic regression analyses indicated that before the intervention the students' level of knowledge about HIV/AIDS was significantly associated with grade, economic status of the family, and attitudes toward participation in HIV/AIDS health information campaigns. HIV/AIDS education programs were welcomed by secondary students and positively influenced HIV/AIDS-related knowledge and attitudes. A systematic and long-term intervention among secondary school students must be conducted for the prevention of HIV.

Objectives. To describe levels of risky sexual behaviour, HIV testing and HIV knowledge among men and women in Guatemala by ethnic group and to identify adjusted associations between ethnicity and these outcomes. Design. Data on 16,205 women aged 15–49 and 6822 men aged 15–59 from the 2008–2009 Encuesta Nacional de Salud Materno Infantil were used to describe ethnic group differences in sexual behaviour, HIV knowledge and testing. We then controlled for age, education, wealth and other socio-demographic factors in a multivariate logistic regression model to examine the effects of ethnicity on outcomes related to age at sexual debut, number of lifetime sex partners, comprehensive HIV knowledge, HIV testing and lifetime sex worker patronage (men only). Results. The data show low levels of risky sexual behaviour and low levels of HIV knowledge among indigenous women and men, compared to other respondents. Controlling for demographic factors, indigenous women were more likely than other women never to have been tested for HIV and to lack comprehensive HIV knowledge. They were less likely to report early sexual debut and three or more lifetime sexual partners. Indigenous men were more likely than other men to lack comprehensive HIV knowledge and demonstrated lower odds of early sexual debut, 10 or more lifetime sexual partners and sex worker patronage. Conclusions. The Mayan indigenous population in Guatemala, while broadly socially vulnerable, does not appear to be at elevated risk for HIV based on this analysis of selected risk factors. Nonetheless, low rates of HIV knowledge and testing may be cause for concern. Programmes working in indigenous communities should focus on HIV education and reducing barriers to testing. Further research into the factors that underlie ethnic self-identity and perceived ethnicity could help clarify the relative significance of these measures for HIV risk and other health outcomes.

High-risk human papillomaviruses (HPVs) are the causes of many cancers, including cervical, anal, vulvar, vaginal, penile and oropharyngeal. To facilitate diagnosis, prognosis and characterization of these cancers, it is necessary to make full use of the immunological data on HPV available through publications, technical reports and databases. These data vary in granularity, quality and complexity. The extraction of knowledge from the vast amount of immunological data using data mining techniques remains a challenging task. To support integration of data and knowledge in virology and vaccinology, we developed a framework called KB-builder to streamline the development and deployment of web-accessible immunological knowledge systems. The framework consists of seven major functional modules, each facilitating a specific aspect of the knowledgebase construction process. Using KB-builder, we constructed the Human Papillomavirus T cell Antigen Database (HPVdb). It contains 2781 curated antigen entries of antigenic proteins derived from 18 genotypes of high-risk HPV and 18 genotypes of low-risk HPV. The HPVdb also catalogs 191 verified T cell epitopes and 45 verified human leukocyte antigen (HLA) ligands. Primary amino acid sequences of HPV antigens were collected and annotated from the UniProtKB. T cell epitopes and HLA ligands were collected from data mining of scientific literature and databases. The data were subject to extensive quality control (redundancy elimination, error detection and vocabulary consolidation). A set of computational tools for an in-depth analysis, such as sequence comparison using BLAST search, multiple alignments of antigens, classification of HPV types based on cancer risk, T cell epitope/HLA ligand visualization, T cell epitope/HLA ligand conservation analysis and sequence variability analysis, has been integrated within the HPVdb. Predicted Class I and Class II HLA binding peptides for 15 common HLA alleles are included in this database as putative targets. HPVdb is a knowledge-based system that integrates curated data and information with tailored analysis tools to facilitate data mining for HPV vaccinology and immunology. To our best knowledge, HPVdb is a unique data source providing a comprehensive list of HPV antigens and peptides. Database URL: http://cvc.dfci.harvard.edu/hpv/ PMID:24705205

2009-01-01

The aim of the present study was to assess the knowledge pregnant women have of infant and baby's feeding as a risk factor for early childhood caries. The study included 200 pregnant women from Plovdiv and the region aged 18 to 41 with different educational backgrounds. A questionnaire was administered to all participants with question related to feeding babies and small children. The results were analysed using alternative analysis, non-parametric (chi2) test, Student t-test and graphic analysis. P < 0.05 was adopted as the level of significance of null hypothesis. The results show a low level of the knowledge pregnant women have of feeding as a potential risk factor for early childhood caries. A great percentage of the women with second and subsequent pregnancies gave wrong answers to at least one of the questions in the questionnaire. Based on the results of the study there is much reason to think that many pregnant women have inadequate knowledge of infant feeding. Introduction of educational programmes is essential with the purpose of raising the mothers' health care awareness in relation to children's dental health.

Background Self-medication with antibiotics (SMA) has been reported among university students in many countries, but little research has been done on this issue in China. The objective of this study was to evaluate knowledge and behaviors of university students and risk factors concerning SMA. Methodology/Principal Findings Using a novel questionnaire-based data collection instrument, an anonymous online survey was conducted with the students of Shantou University (STU), a university comprising 8 schools/colleges in eastern Guangdong, China. Of 1,300 respondents (13.8% of total eligible participants), 47.8% had self-treated with antibiotics. Logistic regression analysis identified prior knowledge of antibiotics (PKA), older age, and higher monthly allowance as independent risk factors for SMA. PKA significantly influenced students' knowledge about antibiotics, their uses, and common adverse reactions (all p<0.05). Among self-medicated students, 61.7% used antibiotics at least twice in the previous year. Community pharmacies were the major source of self-prescribed antibiotics. Reported common indications for SMA were sore throat (59.7%), fever (38.2%), cough (37.4%), runny nose (29.3%), and nasal congestion (28.7%). While 74.1% of self-medication episodes were based on students' own experiences, only 31.1% of students claimed to understand the package insert. Alteration of antibiotics and dosage during the course of self-treatment was made by 63.8% and 55.6% of students, respectively. At least two kinds of antibiotics were simultaneously taken by 82.6% of students. The majority of self-medicated students failed to complete the course of antibiotics. Adverse reactions were reported by 16.3% of students. Amoxicillin was the most common antibiotic used for self-medication. Conclusions High prevalence of SMA was noted among STU students. Presence of risk factors and risk-associated behaviors/attitudes in the study population calls for focused educational intervention and stricter governmental legislation and regulation of antibiotic use and sale in pharmacies.

The objective of the Composite Load Spectra (CLS) project is to develop generic load models to simulate the composite load spectra that are included in space propulsion system components. The probabilistic loads thus generated are part of the probabilistic design analysis (PDA) of a space propulsion system that also includes probabilistic structural analyses, reliability, and risk evaluations. Probabilistic load simulation for space propulsion systems demands sophisticated probabilistic methodology and requires large amounts of load information and engineering data. The CLS approach is to implement a knowledge based system coupled with a probabilistic load simulation module. The knowledge base manages and furnishes load information and expertise and sets up the simulation runs. The load simulation module performs the numerical computation to generate the probabilistic loads with load information supplied from the CLS knowledge base.

Background Comparative risk perceptions may rival other types of information in terms of effects on health behavior decisions. Purpose We examined associations between comparative risk perceptions, affect, and behavior while controlling for absolute risk perceptions and actual risk. Methods Women at an increased risk of breast cancer participated in a program to learn about tamoxifen which can reduce the risk of breast cancer. Women reported comparative risk perceptions of breast cancer and completed measures of anxiety, knowledge, and tamoxifen-related behavior intentions. Three months later, women reported their behavior. Results Comparative risk perceptions were positively correlated with anxiety, knowledge, intentions, and behavior three months later. After controlling for participants’ actual risk of breast cancer and absolute risk perceptions, comparative risk perceptions predicted anxiety and knowledge, but not intentions or behavior. Conclusions Comparative risk perceptions can affect patient outcomes like anxiety and knowledge independently of absolute risk perceptions and actual risk information. PMID:21698518

Web-Based Versus Usual Care and Other Formats of Decision Aids to Support Prostate Cancer Screening Decisions: Systematic Review and Meta-Analysis.

Prostate cancer is a leading cause of cancer among men. Because screening for prostate cancer is a controversial issue, many experts in the field have defended the use of shared decision making using validated decision aids, which can be presented in different formats (eg, written, multimedia, Web). Recent studies have concluded that decision aids improve knowledge and reduce decisional conflict. This meta-analysis aimed to investigate the impact of using Web-based decision aids to support men's prostate cancer screening decisions in comparison with usual care and other formats of decision aids. We searched PubMed, CINAHL, PsycINFO, and Cochrane CENTRAL databases up to November 2016. This search identified randomized controlled trials, which assessed Web-based decision aids for men making a prostate cancer screening decision and reported quality of decision-making outcomes. Two reviewers independently screened citations for inclusion criteria, extracted data, and assessed risk of bias. Using a random-effects model, meta-analyses were conducted pooling results using mean differences (MD), standardized mean differences (SMD), and relative risks (RR). Of 2406 unique citations, 7 randomized controlled trials met the inclusion criteria. For risk of bias, selective outcome reporting and participant/personnel blinding were mostly rated as unclear due to inadequate reporting. Based on seven items, two studies had high risk of bias for one item. Compared to usual care, Web-based decision aids increased knowledge (SMD 0.46; 95% CI 0.18-0.75), reduced decisional conflict (MD -7.07%; 95% CI -9.44 to -4.71), and reduced the practitioner control role in the decision-making process (RR 0.50; 95% CI 0.31-0.81). Web-based decision aids compared to printed decision aids yielded no differences in knowledge, decisional conflict, and participation in decision or screening behaviors. Compared to video decision aids, Web-based decision aids showed lower average knowledge scores (SMD -0.50; 95% CI -0.88 to -0.12) and a slight decrease in prostate-specific antigen screening (RR 1.12; 95% CI 1.01-1.25). According to this analysis, Web-based decision aids performed similarly to alternative formats (ie, printed, video) for the assessed decision-quality outcomes. The low cost, readiness, availability, and anonymity of the Web can be an advantage for increasing access to decision aids that support prostate cancer screening decisions among men. ©Sofia Baptista, Elvira Teles Sampaio, Bruno Heleno, Luís Filipe Azevedo, Carlos Martins.

Is knowledge important? Empirical research on nuclear risk communication in two countries.

Increasing audience knowledge is often set as a primary objective of risk communication efforts. But is it worthwhile focusing risk communication strategies solely on enhancing specific knowledge? The main research questions tackled in this paper were: (1) if prior audience knowledge related to specific radiation risks is influential for the perception of these risks and the acceptance of communicated messages and (2) if gender, attitudes, risk perception of other radiation risks, confidence in authorities, and living in the vicinity of nuclear/radiological installations may also play an important role in this matter. The goal of this study was to test empirically the mentioned predictors in two independent case studies in different countries. The first case study was an information campaign for iodine pre-distribution in Belgium (N = 1035). The second was the information campaign on long-term radioactive waste disposal in Slovenia (N = 1,200). In both cases, recurrent and intensive communication campaigns were carried out by the authorities aiming, among other things, at increasing specific audience knowledge. Results show that higher prior audience knowledge leads to more willingness to accept communicated messages, but it does not affect people’s perception of the specific risk communicated. In addition, the influence of prior audience knowledge on the acceptance of communicated messages is shown to be no stronger than that of general radiation risk perception. The results in both case studies suggest that effective risk communication has to focus not only on knowledge but also on other more heuristic predictors, such as risk perception or attitudes toward communicated risks.

Inside the volcanic boiler room: knowledge exchange among stakeholders of volcanic unrest

Gottsmann, Joachim; Christie, Ryerson; Bretton, Richard

2014-05-01

The knowledge of the causative links between subsurface processes, resulting monitoring signals and imminent eruption is incomplete. As a consequence, hazard assessment and risk mitigation strategies are subject to uncertainty. Discussion of unrest and pre-eruptive scenarios with uncertain outcomes are central during the discourse between a variety of stakeholders in volcanic unrest including scientists, emergency managers, policy makers and the public. Drawing from research within the EC FP7 VUELCO project, we argue that knowledge exchange amongst the different stakeholders of volcanic unrest evolves along three dimensions: 1) the identification of knowledge holders (including local communities) and their needs and expectations, 2) vehicles of communication and 3) trust. In preparing products that feed into risk assessment and management, scientists need to ensure that their deliverables are timely, accurate, clear, understandable and cater to the expectations of emergency managers. The means and content of communication amongst stakeholders need to be defined and adhered to. Finally, efficient and effective interaction between stakeholders is ideally based on mutual trust between those that generate knowledge and those that receive knowledge. For scientists, this entails contextualising volcanic hazard and risk in the framework of environmental and social values. Periods of volcanic quiescence are ideally suited to test established protocols of engagement between stakeholders in preparation for crises situations. The different roles of stakeholders and associated rules of engagement can be scrutinised and reviewed in antecessum rather than ad-hoc during a crisis situation to avoid issues related to distrust, loss of credibility and overall poor risk management. We will discuss these themes drawing from exploitation of research results from Mexico and Ecuador.

Knowledge, attitudes and practices of malaria in Colombia

PubMed Central

2014-01-01

Background Although Colombia has witnessed an important decrease in malaria transmission, the disease remains a public health problem with an estimated ~10 million people currently living in areas with malaria risk and ~61,000 cases reported in 2012. This study aimed to determine and compare the level of knowledge, attitudes and practices (KAP) about malaria in three endemic communities of Colombia to provide the knowledge framework for development of new intervention strategies for malaria elimination. Methods A cross-sectional KAP survey was conducted in the municipalities of Tierralta, Buenaventura and Tumaco, categorized according to high risk (HR) and moderate risk (MR) based on the annual parasite index (API). Surveys were managed using REDCap and analysed using MATLAB and GraphPad Prism. Results A total of 267 residents, mostly women (74%) were surveyed. Although no differences were observed on the knowledge of classical malaria symptoms between HR and MR regions, significant differences were found in knowledge and attitudes about transmission mechanisms, anti-malarial use and malaria diagnosis. Most responders in both regions (93.5% in MR, and 94.3% in HR areas) indicated use of insecticide-treated nets (ITNs) to protect themselves from malaria, and 75.5% of responders in HR indicated they did nothing to prevent malaria transmission outdoors. Despite a high level of knowledge in the study regions, significant gaps persisted relating to practices. Self-medication and poor adherence to treatment, as well as lack of both indoor and outdoor vector control measures, were significantly associated with higher malaria risk. Conclusions Although significant efforts are currently being made by the Ministry of Health to use community education as one of the main components of the control strategy, these generic education programmes may not be applicable to all endemic regions of Colombia given the substantial geographic, ethnic and cultural diversity.

Breast cancer risks and risk prediction models.

PubMed

Engel, Christoph; Fischer, Christine

2015-02-01

BRCA1/2 mutation carriers have a considerably increased risk to develop breast and ovarian cancer. The personalized clinical management of carriers and other at-risk individuals depends on precise knowledge of the cancer risks. In this report, we give an overview of the present literature on empirical cancer risks, and we describe risk prediction models that are currently used for individual risk assessment in clinical practice. Cancer risks show large variability between studies. Breast cancer risks are at 40-87% for BRCA1 mutation carriers and 18-88% for BRCA2 mutation carriers. For ovarian cancer, the risk estimates are in the range of 22-65% for BRCA1 and 10-35% for BRCA2. The contralateral breast cancer risk is high (10-year risk after first cancer 27% for BRCA1 and 19% for BRCA2). Risk prediction models have been proposed to provide more individualized risk prediction, using additional knowledge on family history, mode of inheritance of major genes, and other genetic and non-genetic risk factors. User-friendly software tools have been developed that serve as basis for decision-making in family counseling units. In conclusion, further assessment of cancer risks and model validation is needed, ideally based on prospective cohort studies. To obtain such data, clinical management of carriers and other at-risk individuals should always be accompanied by standardized scientific documentation.

Optical systems are extensively utilized by industry government and military organizations. The conceptual design engineering design fabrication and testing of these systems presently requires significant time typically on the order of 3-5 years. The Knowledge-Based Environment for Optical System Design (KB-OSD) Program has as its principal objectives the development of a methodology and tool(s) that will make a notable reduction in the development time of optical system projects reduce technical risk and overall cost. KB-OSD can be considered as a computer-based optical design associate for system engineers and design engineers. By utilizing artificial intelligence technology coupled with extensive design/evaluation computer application programs and knowledge bases the KB-OSD will provide the user with assistance and guidance to accomplish such activities as (i) develop system level and hardware level requirements from mission requirements (ii) formulate conceptual designs (iii) construct a statement of work for an RFP (iv) develop engineering level designs (v) evaluate an existing design and (vi) explore the sensitivity of a system to changing scenarios. The KB-OSD comprises a variety of computer platforms including a Stardent Titan supercomputer numerous design programs (lens design coating design thermal materials structural atmospherics etc. ) data bases and heuristic knowledge bases. An important element of the KB-OSD Program is the inclusion of the knowledge of individual experts in various areas of optics and optical system engineering. This knowledge is obtained by KB-OSD knowledge engineers performing

This manuscript describes the follow-up study of our previous publication on the presence and risks of nanosilica in food. New information on the presence of nanosilica in the gastrointestinal tract is evaluated and information on nanosilica and synthetic amorphous silica (SAS) is compared to assess its relevance for risk assessment of nanosilica in food. Irrespective of whether SAS should be regarded as a nanomaterial or a non-nanoform of silica, a comparison to nanosilica is relevant to determine whether there are differences in physicochemical properties, which may lead to differences in toxicity. Based on this comparison, knowledge gaps are identified and recommendations for a targeted approach to facilitate risk assessment of nanosilica in food are given. Considering the discussion to which extent nanomaterials with (slightly) different physicochemical characteristics can be grouped for risk assessment--the sameness issue--actual exercises as presented in this manuscript are highly relevant for bringing this discussion forward.

Objective This study aimed to build formative knowledge on socio-structural barriers, protective factors, and HIV sexual risk amongst Central-Asian female migrants in Moscow. Methods Data collection included ethnographic interviews in Moscow with a purposive sample of 30 unmarried female migrants, 15 from Kyrgyzstan and 15 from Tajikistan. Results Study participants reported difficulties with acquiring documents for legal status, financial insecurity, discrimination, sexual harassment, and lack of support. Based on analysis of the cases, one pathway linked lack of legal documentation and instrumental support with elevated sexual risk. Another pathways linked traditional cultural attitudes with both no and moderate sexual risk. Conclusion Future HIV prevention efforts with Central Asian female migrants in Moscow should be multilevel and include: increasing HIV and prevention knowledge and skills, promoting condom use with regular partners, identifying and supporting cultural attitudes that protect against HIV sexual risk behaviors, facilitating legal status, building community support, and increasing economic options.

Incorporation of Personal Single Nucleotide Polymorphism (SNP) Data into a National Level Electronic Health Record for Disease Risk Assessment, Part 3: An Evaluation of SNP Incorporated National Health Information System of Turkey for Prostate Cancer

Beyan, Timur

Background A personalized medicine approach provides opportunities for predictive and preventive medicine. Using genomic, clinical, environmental, and behavioral data, the tracking and management of individual wellness is possible. A prolific way to carry this personalized approach into routine practices can be accomplished by integrating clinical interpretations of genomic variations into electronic medical records (EMRs)/electronic health records (EHRs). Today, various central EHR infrastructures have been constituted in many countries of the world, including Turkey. Objective As an initial attempt to develop a sophisticated infrastructure, we have concentrated on incorporating the personal single nucleotide polymorphism (SNP) data into the National Health Information System of Turkey (NHIS-T) for disease risk assessment, and evaluated the performance of various predictive models for prostate cancer cases. We present our work as a three part miniseries: (1) an overview of requirements, (2) the incorporation of SNP data into the NHIS-T, and (3) an evaluation of SNP data incorporated into the NHIS-T for prostate cancer. Methods In the third article of this miniseries, we have evaluated the proposed complementary capabilities (ie, knowledge base and end-user application) with real data. Before the evaluation phase, clinicogenomic associations about increased prostate cancer risk were extracted from knowledge sources, and published predictive genomic models assessing individual prostate cancer risk were collected. To evaluate complementary capabilities, we also gathered personal SNP data of four prostate cancer cases and fifteen controls. Using these data files, we compared various independent and model-based, prostate cancer risk assessment approaches. Results Through the extraction and selection processes of SNP-prostate cancer risk associations, we collected 209 independent associations for increased risk of prostate cancer from the studied knowledge sources. Also, we gathered six cumulative models and two probabilistic models. Cumulative models and assessment of independent associations did not have impressive results. There was one of the probabilistic, model-based interpretation that was successful compared to the others. In envirobehavioral and clinical evaluations, we found that some of the comorbidities, especially, would be useful to evaluate disease risk. Even though we had a very limited dataset, a comparison of performances of different disease models and their implementation with real data as use case scenarios helped us to gain deeper insight into the proposed architecture. Conclusions In order to benefit from genomic variation data, existing EHR/EMR systems must be constructed with the capability of tracking and monitoring all aspects of personal health status (genomic, clinical, environmental, etc) in 24/7 situations, and also with the capability of suggesting evidence-based recommendations. A national-level, accredited knowledge base is a top requirement for improved end-user systems interpreting these parameters. Finally, categorization using similar, individual characteristics (SNP patterns, exposure history, etc) may be an effective way to predict disease risks, but this approach needs to be concretized and supported with new studies.

Although nurses historically have responded to natural disasters, little is known about nurses' intentions to respond during bioterrorism and other infectious disease emergencies where they and their families may be at risk. To investigate that question, we surveyed nurses following their participation in a class on bioterrorism. Participants (N = 292) completed a Personal/Professional Profile (PPP), Test of Bioterrorism Knowledge (BT Knowledge), and an Intention to Respond (IR) instrument. IR was measured by participants' scores on their likelihood to care for patients (0 = extremely unlikely, 10 = extremely likely) for each of 10 infectious disease scenarios reflecting different infection risk. We calculated scores for each scenario, totaled them, and examined the total IR related to the participant's PPP and scores on BT Knowledge. Additionally, we examined participants' written comments explaining the reasons for their IR. Total IR scores ranged from 8-100 (mean and median of 70). The IR was higher in scenarios where the infection risk was lower. Overall IR scores were positively related to BT Knowledge and having had previous emergency and disaster experience. Those less likely to respond had dependent children and more years in nursing. Results indicate that nurses differentiated risks associated with different infectious disease situations and may decide to respond during a real emergency based on such information. Implications for nursing administrators and nursing educators are discussed. Copyright 2010 Mosby, Inc. All rights reserved.

Among 11-12 year-old girls who received the human papillomavirus (HPV) vaccine, we explored, over the subsequent 30 months: (1) trajectories of knowledge about HPV/HPV vaccines and vaccine-related risk perceptions; (2) whether knowledge and risk perceptions impacted sexual attitudes and sexual experience; (3) whether mothers, clinicians, and media influenced girls' risk perceptions, attitudes, and behavior. Girls and mothers (n=25dyads) completed separate, semi-structured interviews within 2 days of, and 6, 18, and 30 months after, their first HPV vaccine dose. Knowledge, risk perceptions related to HPV and other sexually transmitted infections (STIs), and attitudes about sexual behaviors were assessed. Sexual experience was assessed at girls' 30 month interviews. Clinicians completed interviews at baseline. Transcribed interviews were analyzed using framework analysis. Girls' baseline knowledge was poor but often improved with time. Most girls (n=18) developed accurate risk perceptions about HPV but only half (n=12) developed accurate risk perceptions about other STIs by 30 months. The vast majority of girls thought that safer sex was still important, regardless of knowledge, risk perceptions, or sexual experience. Girls whose HPV knowledge was high at baseline or increased over time tended to articulate accurate risk perceptions; those who were able to articulate accurate risk perceptions tended to report not having initiated sexual activity. Girls whose mothers demonstrated higher knowledge and/or communication about HPV vaccination tended to articulate accurate risk perceptions, whereas clinicians and media exposure did not appear to influence risk perceptions. Higher knowledge about HPV vaccines among mothers and girls was linked with more accurate risk perceptions among girls. Clinicians may play an important role in providing education about HPV vaccines to mothers and girls. Copyright © 2015 Elsevier Ltd. All rights reserved.

Young people are at an increased risk for illness in working life. The authorities stipulate certain goals for training in occupational health and safety (OHS) in vocational schools. A previous study concluded that pupils in vocational education had limited knowledge in the prevention of health risks at work. The aim of the current study, therefore, was to study how OHS training is organized in school and in workplace-based learning (WPL). The study design featured a qualitative approach, which included interviews with 12 headmasters, 20 teachers, and 20 supervisors at companies in which the pupils had their WPL. The study was conducted at 10 upper secondary schools, located in Central Sweden, that were graduating pupils in four vocational programs. The interviews with headmasters, teachers, and supervisors indicate a staggered picture of how pupils are prepared for safe work. The headmasters generally give teachers the responsibility for how goals should be reached. Teaching is very much based on risk factors that are present in the workshops and on teachers' own experiences and knowledge. The teaching during WPL also lacks the systematic training in OHS as well as in the traditional classroom environment. Teachers and supervisors did not plan the training in OHS in accordance with the provisions of systematic work environment management. Instead, the teachers based the training on their own experiences. Most of the supervisors did not receive information from the schools as to what should be included when introducing OHS issues in WPL.

In Search of Perfect Foresight? Policy Bias, Management of Unknowns, and What Has Changed in Science Policy Since the Tohoku Disaster.

The failure to foresee the catastrophic earthquakes, tsunamis, and nuclear accident of 2011 has been perceived by many in Japan as a fundamental shortcoming of modern disaster risk science. Hampered by a variety of cognitive and institutional biases, the conventional disaster risk management planning based on the "known risks" led to the cascading failures of the interlinked disaster risk management (DRM) apparatus. This realization led to a major rethinking in the use of science for policy and the incorporations of lessons learned in the country's new DRM policy. This study reviews publicly available documents on expert committee discussions and scientific articles to identify what continuities and changes have been made in the use of scientific knowledge in Japanese risk management. In general, the prior influence of cognitive bias (e.g., overreliance on documented hazard risks) has been largely recognized, and increased attention is now being paid to the incorporation of less documented but known risks. This has led to upward adjustments in estimated damages from future risks and recognition of the need for further strengthening of DRM policy. At the same time, there remains significant continuity in the way scientific knowledge is perceived to provide sufficient and justifiable grounds for the development and implementation of DRM policy. The emphasis on "evidence-based policy" in earthquake and tsunami risk reduction measures continues, despite the critical reflections of a group of scientists who advocate for a major rethinking of the country's science-policy institution respecting the limitations of the current state science. © 2016 Society for Risk Analysis.

The virtual test bed for launch and range operations developed at NASA Ames Research Center consists of various independent expert systems advising on weather effects, toxic gas dispersions and human health risk assessment during space-flight operations. An individual dedicated server supports each expert system and the master system gather information from the dedicated servers to support the launch decision-making process. Since the test bed is based on the web system, reducing network traffic and optimizing the knowledge base is critical to its success of real-time or near real-time operations. Jess, a fast rule engine and powerful scripting environment developed at Sandia National Laboratory has been adopted to build the expert systems providing robustness and scalability. Jess also supports XML representation of knowledge base with forward and backward chaining inference mechanism. Facts added - to working memory during run-time operations facilitates analyses of multiple scenarios. Knowledge base can be distributed with one inference engine performing the inference process. This paper discusses details of the knowledge base and inference engine using Jess for a launch and range virtual test bed.

To gain insight into the knowledge and attitudes of nurses and nursing assistants and to study the correlation between knowledge, attitudes and the compliance with the pressure ulcer prevention guidelines provided to residents at risk of pressure ulcers in nursing homes. There is a lack of evidence on knowledge and attitudes of nurses and nursing assistants towards pressure ulcer prevention in nursing homes. A cross-sectional multi-centre study. A convenience sample of nine Belgian nursing homes, representing 18 wards was chosen in the study. In total, 145 nurses and nursing assistants were included. The compliance with the guidelines was evaluated in 615 residents, and data were collected using validated instruments. Fully compliant prevention was found in only 6·9% of the residents at risk. The mean knowledge score of the nurses was 29·3 vs. 28·7% for the nursing assistants. The overall attitude score was 74·5%, and attitude scores were significantly different between nurses and nursing assistants. Nurses showed to have a more positive attitude towards pressure ulcer prevention than nursing assistants, respectively 78·3 and 72·3%. A more positive attitude was a significant predictor of pressure ulcer prevention compliance with the guidelines provided to residents at risk of pressure ulcers in nursing homes. Knowledge about pressure ulcer prevention of both nurses and nursing assistants in nursing homes was low. Attitudes were a significant predictor of the application of fully compliant prevention in residents at risk. Pressure ulcer prevention is an important aspect in daily care for residents at risk in nursing homes. These insights will contribute to evidence-based practice in this area of care and will form the basis for the development of an education strategy for pressure ulcer prevention and management in nursing homes. © 2011 Blackwell Publishing Ltd.

Awareness of Cardiovascular Disease and Preventive Behaviors Among Overweight Immigrant Latinas.

Low-income Latina women face increased risk for cardiovascular disease (CVD) due to high rates of obesity, diabetes, and other comorbidities. Language barriers, lack of health insurance, and lack of access to preventive health messages may further increase their risk. The purpose of this study was to evaluate knowledge about CVD of overweight, immigrant Latinas who spoke little or no English and participated in an educational intervention. Ninety participants completed a CVD knowledge questionnaire before and after 8 educational sessions based upon Su Corazón, Su Vida. The curriculum focused on understanding risk factors of CVD and prevention through heart-healthy diets, physical activity, and weight control. The questionnaire evaluated general CVD knowledge (eg, heart disease is the leading cause of death in women) and prevention measures (eg, physical activity can lower a woman's risk for getting heart disease). Data were analyzed using generalized estimating equations and correlational statistics. Participants were middle-aged, overweight Latinas, predominantly of Mexican descent, with low education and acculturation. Baseline knowledge that heart disease is the leading cause of death in women was low. A comparison of preintervention and postintervention scores on the questionnaire showed a significant change (P < 0.001), with means of 7.9 and 9.4, respectively. Scores for individual items correctly answered significantly improved for 9 of the 11 items, including questions about portion control to lose weight, physical activity, overweight, and risk for heart disease. Most participants did not recognize that men and women may experience different symptoms of a heart attack. Knowledge was not significantly related to background characteristics, body mass index, or lifestyle behaviors. Despite campaigns to increase CVD awareness, many Spanish-speaking, immigrant Latinas remain unaware that heart disease is the leading cause of death. Educational interventions may significantly improve their CVD knowledge; nonetheless, continued cardiovascular health promotion efforts are needed for this population.

The knowledge, attitudes and practices of wintersun vacationers to the Gambia toward prevention of malaria: is it really that bad?

Background Each year clusters of imported malaria cases are observed in Dutch wintersun vacationers returning from The Gambia. To gain more insight in the travel health preparation and awareness of these travellers, the knowledge, attitudes and practices (KAP) of this travel group was studied by analysing the data of the Continuous Dutch Schiphol Airport Survey. Methods In the years 2002 to 2009 a questionnaire-based survey was conducted at the Dutch Schiphol Airport with the aim to study the KAP, i.e. accuracy of risk perception (“knowledge”), intended risk-avoiding behaviour (“attitude”) and use of personal protective measures and malaria chemoprophylaxis (“practice”) toward prevention malaria in travellers to The Gambia. Travellers to other high-risk destinations served as controls. Results The KAP of travellers to The Gambia toward prevention of malaria was significantly better than that observed in other travellers. Trend analyses indicated that attitude improved over time in both groups but knowledge did not change. Only in travellers to high-risk countries other than The Gambia significant increases in protection rates were observed over time. Conclusions The KAP of travellers to The Gambia toward prevention of malaria was better than that observed in travellers to destinations other than The Gambia. Trend analyses revealed a significant improvement of intended risk avoiding behaviour but not in protection rates or risk perception. PMID:24581328

This study assessed the knowledge of heart attack symptoms and risk factors in a convenience sample of Korean immigrants. A total of 116 Korean immigrants in a Midwestern metropolitan area were recruited through Korean churches and markets. Knowledge was assessed using both open-ended questions and a structured questionnaire. Latent class cluster analysis and Chi-square tests were used to analyze the data. About 76% of the sample had at least one self-reported risk factor for cardiovascular disease. Using an open-ended question, the majority of subjects could only identify one symptom. In the structured questionnaire, subjects identified a mean of 5 out of 10 heart attack symptoms and a mean of 5 out of 9 heart attack risk factors. Latent class cluster analysis showed that subjects clustered into two groups for both risk factors and symptoms: a high knowledge group and a low knowledge group. Subjects who clustered into the risk factor low knowledge group (48%) were more likely than the risk factor high knowledge group to be older than 65 years, to have lower education, to not know to use 911 when a heart attack occurred, and to not have a family history of heart attack. Korean immigrants' knowledge of heart attack symptoms and risk factors was variable, ranging from high to very low. Education should be focused on those at highest risk for a heart attack, which includes the elderly and those with risk factors.

Risk Information Management Resource (RIMR): modeling an approach to defending against military medical information assurance brain drain

2003-05-01

As Military Medical Information Assurance organizations face off with modern pressures to downsize and outsource, they battle with losing knowledgeable people who leave and take with them what they know. This knowledge is increasingly being recognized as an important resource and organizations are now taking steps to manage it. In addition, as the pressures for globalization (Castells, 1998) increase, collaboration and cooperation are becoming more distributed and international. Knowledge sharing in a distributed international environment is becoming an essential part of Knowledge Management. This is a major shortfall in the current approach to capturing and sharing knowledge in Military Medical Information Assurance. This paper addresses this challenge by exploring Risk Information Management Resource (RIMR) as a tool for sharing knowledge using the concept of Communities of Practice. RIMR is based no the framework of sharing and using knowledge. This concept is done through three major components - people, process and technology. The people aspect enables remote collaboration, support communities of practice, reward and recognize knowledge sharing while encouraging storytelling. The process aspect enhances knowledge capture and manages information. While the technology aspect enhance system integration and data mining, it also utilizes intelligent agents and exploits expert systems. These coupled with supporting activities of education and training, technology infrastructure and information security enables effective information assurance collaboration.

Trends in the knowledge, attitudes and practices of travel risk groups towards prevention of malaria: results from the Dutch Schiphol Airport Survey 2002 to 2009

PubMed Central

2012-01-01

Background Previous studies investigating the travellers’ knowledge, attitudes and practices (KAP) profile indicated an important educational need among those travelling to risk destinations. Initiatives to improve such education should target all groups of travellers, including business travellers, those visiting friends and relatives (VFRs), and elderly travellers. Methods In the years 2002 to 2009, a questionnaire-based survey was conducted at the Dutch Schiphol Airport with the aim to study trends in KAP of travel risk groups towards prevention of malaria. The risk groups last-minute travellers, solo-travellers, business travellers, VFRs and elderly travellers were specifically studied. Results A total of 3,045 respondents were included in the survey. Travellers to destinations with a high risk for malaria had significantly more accurate risk perceptions (knowledge) than travellers to low-risk destinations. The relative risk for malaria in travellers to high-risk destinations was probably mitigated by higher protection rates against malaria as compared with travellers to low risk destinations. There were no significant differences in intended risk-taking behaviour. Trend analyses showed a significant change over time in attitude towards more risk-avoiding behaviour and towards higher protection rates against malaria in travellers to high-risk destinations. The KAP profile of last-minute travellers substantially increased their relative risk for malaria, which contrasts to the slight increase in relative risk of solo travellers, business travellers and VFRs for malaria. Conclusions The results of this sequential cohort survey in Dutch travellers suggest an annual 1.8% increase in protection rates against malaria coinciding with an annual 2.5% decrease in intended risk-seeking behaviour. This improvement may reflect the continuous efforts of travel health advice providers to create awareness and to propagate safe and healthy travel. The KAP profile of last-minute travellers, in particular, substantially increased their relative risk for malaria, underlining the continuous need for personal protective measures and malaria chemoprophylaxis for this risk group.

Dog-bite injuries pose significant threat to children globally. School-age children are especially at risk because of their insufficient safety knowledge and cognitively immature tendency toward low perceived vulnerability to bites, and this risk is elevated further for school-age children living in rural China due to the large number of stray dogs, all potential rabies carriers, present in their communities. This randomized controlled trial evaluated whether viewing an educational video of testimonials would change safety knowledge, perceived vulnerability, and simulated behaviors with dogs among a sample of 280 third and fourth graders living in rural China. Participants were randomly assigned to view either an educational video of testimonials on dog-bite prevention (treatment) or an educational video of testimonials on drowning prevention (comparison). Safety knowledge, perceived vulnerability to dog bites, and simulated behavior with dogs using a dollhouse model were assessed both before and after exposure to the video of testimonials. Children who watched the educational video of testimonials on dog-bite prevention had increased safety knowledge, higher perceived vulnerability, and less risky simulated behaviors with dogs compared with the comparison group. Mediation analysis revealed that the intervention successfully changed children's simulated behaviors with dogs through greater safety knowledge and increased perceived vulnerability. Results suggest the incorporation of testimonials into injury prevention programs has potential for broad global dissemination. The fact that both increased knowledge and heightened perceived vulnerability mediated changes in simulated behavior suggests the dual roles of knowledge and appraisal on children's injury-risk behavior.

To control the latent social risk of disease, the government usually spreads accurate information and attempts to improve the public's attitude toward adopting prevention. However, these methods with the Knowledge, Attitudes, and Practices (KAP) model do not always work. Therefore, we used the theory of planned behavior (TPB) to understand dog owners' behavior and distinguished the knowledge effect as objective knowledge (OK) and subjective knowledge (SK). A total of 310 dog owners completed a questionnaire based on our model. We employed structural equation modeling to verify the structural relationships and found three main results. First, our model was fit, and each path was significant. People with better attitudes, stronger subjective norms, and more perceptive behavioral control have stronger behavioral intention. Second, perceived behavioral control, not attitude, was the best predictive index in this model. Finally, on perceived behavioral control, subjective knowledge showed more influence than objective knowledge. We successfully extended TPB to explain the behavioral intention of dog owners and presented more workable recommendations. To reduce the latent social risk of disease, the government should not only address dog owners' attitudes, but also their subjective norms and perceptive behavioral control. Indeed, perceptive behavioral control and SK showed the most influence in this model. It is implied that the self-efficacy of dog owners is the most important factor in such a behavior. Therefore, the government should focus on enhancing dog owners' self-efficacy first while devoted to prevention activities.

Unwanted teenage pregnancy, sexually transmitted infections and the attendant morbidity and mortality necessitate the need for understanding factors influencing adolescent sexuality and the implementation of programmes designed to improve their knowledge, reproductive behaviour, sexual and reproductive health. To determine the impact of an intervention package on knowledge levels of various reproductive health issues through trend analysis. Randomized controlled trial of a health education intervention in schools stratified for representativeness. Rural and urban secondary schools in Zimbabwe. 1,689 students recruited from 11 secondary schools in Mashonaland Central. Knowledge level before and after intervention. The demographic characteristics of the pupils at baseline, five months and nine months were comparable between the two groups. There was an overall increase in knowledge on menstruation. Students from the intervention schools were more likely to have correct knowledge over time on aspects of reproductive biology. A significant linear trend (p = 0.017) was observed in the area of family planning and contraception. A linear decreasing trend (p = 0.001) was observed on pregnancy risk. Though not significantly linear, the general trend of knowledge levels in all the areas of reproductive health, pregnancy risk, STDs and HIV/AIDS showed an upward trend, from 20% to 96%. Worth noting was that in all the areas the intervention group had knowledge above that in the control group. The reproductive health education intervention had an impact on aspects of reproductive biology and contraception as measured by the increased scoring at follow up when comparing intervention and control schools. The overall findings point to the need for early school based reproductive health education programmes incooperating correct information on reproductive biology and the prevention of subsequent reproductive morbidity by imparting information on non-risk behaviour during the early developmental years.

African faith-based organization (FBO) leaders influence their members' HIV knowledge, beliefs, and practices, but their roles in HIV prevention and care are poorly understood. This article expands the work of Garner (2000) to test the impact of FBO influence on member risk and care behaviors, embedding it in the Theory of Planned Behavior. Qualitative interviews and quantitative surveys were collected from five FBOs (Christian and Muslim) in Malawi and analyzed using mixed methods. Contrary to Garner, we found that the level of power and influence of the FBO had no significant impact on the risk-taking behaviors of members; however, leaders' HIV knowledge predicted members' behaviors. Stigmatizing attitudes of leaders significantly decreased members' care behaviors, but FBO hierarchy tended to increase members' care behaviors. The power of local church and mosque leaders to influence behavior could be exploited more effectively by nurses by providing support, knowledge, and encouragement to churches and mosques.

Intelligent sensors experience security problems very similar to those inherent to other kinds of IT products or systems. The assurance for these products or systems creation methodologies, like Common Criteria (ISO/IEC 15408) can be used to improve the robustness of the sensor systems in high risk environments. The paper presents the background and results of the previous research on patterns-based security specifications and introduces a new ontological approach. The elaborated ontology and knowledge base were validated on the IT security development process dealing with the sensor example. The contribution of the paper concerns the application of the knowledge engineering methodology to the previously developed Common Criteria compliant and pattern-based method for intelligent sensor security development.

Purpose To assess the impact of the education program of the Eye Care Quality and Accessibility Improvement in the Community (EQUALITY) telemedicine program on at-risk patients’ knowledge about glaucoma and attitudes about eye care as well as to assess patient satisfaction with EQUALITY. Patients and methods New or existing patients presenting for a comprehensive eye exam (CEE) at one of two retail-based primary eye clinics were enrolled based on ≥1 of the following at-risk criteria for glaucoma: African Americans ≥40 years of age, Whites ≥50 years of age, diabetes, family history of glaucoma, and/or preexisting diagnosis of glaucoma. A total of 651 patients were enrolled. A questionnaire was administered prior to the patients’ CEE and prior to the patients receiving any of the evidence-based eye health education program; a follow-up questionnaire was administered 2–4 weeks later by phone. Baseline and follow-up patient responses regarding knowledge about glaucoma and attitudes about eye care were compared using McNemar’s test. Logistic regression models were used to assess the association of patient-level characteristics with improvement in knowledge and attitudes. Overall patient satisfaction was summarized. Results At follow-up, all patient responses in the knowledge and attitude domains significantly improved from baseline (P≤0.01 for all questions). Those who were unemployed (odds ratio =0.63, 95% confidence interval =0.42–0.95, P=0.026) or had lower education (odds ratio =0.55, 95% confidence interval =0.29–1.02, P=0.058) were less likely to improve their knowledge after adjusting for age, sex, race, and prior glaucoma diagnosis. This association was attenuated after further adjustment for other patient-level characteristics. Ninety-eight percent (n=501) of patients reported being likely to have a CEE within the next 2 years, whereas 63% (n=326) had a CEE in the previous 2 years. Patient satisfaction with EQUALITY was high (99%). Conclusion Improved knowledge about glaucoma and a high intent to pursue eye care may lead to improved detection of early disease, thus lowering the risk of blindness. PMID:27274329

Detection and follow-up of chronic obstructive pulmonary disease (COPD) and risk factors in the Southern Cone of Latin America: the pulmonary risk in South America (PRISA) study.

The World Health Organization has estimated that by 2030, chronic obstructive pulmonary disease will be the third leading cause of death worldwide. Most knowledge of chronic obstructive pulmonary disease is based on studies performed in Europe or North America and little is known about the prevalence, patient characteristics and change in lung function over time in patients in developing countries, such as those of Latin America. This lack of knowledge is in sharp contrast to the high levels of tobacco consumption and exposure to biomass fuels exhibited in Latin America, both major risk factors for the development of chronic obstructive pulmonary disease. Studies have also demonstrated that most Latin American physicians frequently do not follow international chronic obstructive pulmonary disease diagnostic and treatment guidelines. The PRISA Study will expand the current knowledge regarding chronic obstructive pulmonary disease and risk factors in Argentina, Chile and Uruguay to inform policy makers and health professionals on the best policies and practices to address this condition. PRISA is an observational, prospective cohort study with at least four years of follow-up. In the first year, PRISA has employed a randomized three-staged stratified cluster sampling strategy to identify 6,000 subjects from Marcos Paz and Bariloche, Argentina, Temuco, Chile, and Canelones, Uruguay. Information, such as comorbidities, socioeconomic status and tobacco and biomass exposure, will be collected and spirometry, anthropometric measurements, blood sampling and electrocardiogram will be performed. In year four, subjects will have repeat measurements taken. There is no longitudinal data on chronic obstructive pulmonary disease incidence and risk factors in the southern cone of Latin America, therefore this population-based prospective cohort study will fill knowledge gaps in the prevalence and incidence of chronic obstructive pulmonary disease, patient characteristics and changes in lung function over time as well as quality of life and health care resource utilization. Information gathered during the PRISA Study will inform public health interventions and prevention practices to reduce risk of COPD in the region.

Multifactorial strategies that prevent or delay the onset or progress of cognitive decline and dementia are needed, and should include education regarding recognized risk factors. The current study sought to investigate whether older adults "at risk" of cognitive decline benefit from psychoeducation targeting healthy brain aging. 65 participants (mean age 64.8 years, SD 9.6) with a lifetime history of major depression; vascular risk as evidenced by at least one vascular risk factor; and/or subjective or objective memory impairment were allocated to weekly psychoeducation sessions or a waitlist control group. The small group sessions were conducted over ten weeks by a team of medical and allied health professionals with expertise in late-life depression and cognition. Sessions focused on modifiable risk factors for cognitive decline including vascular risk, diet, exercise, depression, anxiety and sleep disturbance, as well as providing practical strategies for memory and cognition. Both the psychoeducation and waitlist group completed a 20-item knowledge test at baseline and follow-up. Participants in the psychoeducation group were asked to complete follow-up self-report satisfaction questionnaires. Repeated measures ANOVA showed a significant interaction effect depicting improvements in knowledge associated with psychoeducation, corresponding to an improvement of 15% from baseline. Satisfaction data additionally showed that 92.3% of participants rated the program as "good" to "excellent", and over 90% suggested they would recommend it to others. A group-based psychoeducation program targeting healthy brain aging is effective in improving knowledge. Additionally, it is acceptable and rated highly by participants.

Psychosocial risks in the workplace: an increasing challenge for german and international health protection.

PubMed

Portuné, Roland

2012-06-01

Occupational health in a changing world has to face up to psychosocial risks to protect the health of employees now and in the future. Faster production, service and communication processes, a service- and knowledge-based society, an increasing proportion of intellectual work, growing complexity of work-related demands, new technologies and constant availability, mobility demands, and job insecurity contribute to the problem of psychosocial risks in the workplace. Psychosocial risks affect both physical and psychosocial health. There is scientific evidence of the link between psychosocial work-related stress and cardiovascular diseases, affective disorders or musculoskeletal disorders, especially chronic back pain.The Framework Directive on Safety and Health makes it very clear that employers are obliged "to ensure the safety and health of workers in every aspect relating to work". In spite of these far reaching obligations, a kind of taboo sometimes makes it hard to focus on topics that have psychosocial implications. A large number of models, instruments and methods are now available to gauge psychosocial risks in the workplace. Given the clear contrast between knowledge and application, there is not a lack of knowledge in this regard, but rather a lack of application.In Germany, statutory accident insurance institutions are guided by two key principles: putting prevention before rehabilitation and rehabilitation before compensation. To prevent work-related health risks the BG RCI has developed several prevention tools to help employers and employees deal with psychosocial risks in the workplace.

Surface knowledge and risks to landing and roving - The scale problem

Bourke, Roger D.

1991-01-01

The role of surface information in the performance of surface exploration missions is discussed. Accurate surface models based on direct measurements or inference are considered to be an important component in mission risk management. These models can be obtained using high resolution orbital photography or a combination of laser profiling, thermal inertia measurements, and/or radar. It is concluded that strategies for Martian exploration should use high confidence models to achieve maximum performance and low risk.

While most children with cancer survive their initial disease, cancer therapy places them at risk for late effects (LE). Knowledge of their diagnosis, treatment, and LE risk may motivate survivors to attend long-term follow-up care. The aims of this study were to examine knowledge of cancer history and future risks, and to identify factors associated with such knowledge, in a cohort of childhood cancer survivors. Survivors (i.e., patients finished cancer treatment, regardless of time since completion) aged 15 to 26 years from three Canadian cancer centers were invited to complete a questionnaire that assessed knowledge of cancer history and potential LE of treatments, including five specific LE known to have considerable long-term health impact. Clinical data were extracted from hospital records and used to validate participants' answers. Of 250 participants, 16 (6%) were unable to name their cancer, 79 (32%) had partial or no knowledge of their therapy, and 83 (33%) were unaware of at least some of their risks for LE. Decreasing age (OR for increase in age = 1.2 (1.1-1.4)), having had a renal tumor compared to leukemia (OR = 0.3 (0.1-0.9)), and lacking knowledge about treatment (OR = 0.4 (0.2-0.9)) were associated with lack of knowledge of LE. Of the five, the most and least familiar LE was LE associated with impaired pulmonary function and risk of second malignancy, respectively. This study highlights knowledge deficits in survivors, specifically regarding their risk for LE. Findings can be utilized to target survivors at risk for knowledge deficits.

Integrating legal liabilities in nanomanufacturing risk management.

2012-08-07

Among other things, the wide-scale development and use of nanomaterials is expected to produce costly regulatory and civil liabilities for nanomanufacturers due to lingering uncertainties, unanticipated effects, and potential toxicity. The life-cycle environmental, health, and safety (EHS) risks of nanomaterials are currently being studied, but the corresponding legal risks have not been systematically addressed. With the aid of a systematic approach that holistically evaluates and accounts for uncertainties about the inherent properties of nanomaterials, it is possible to provide an order of magnitude estimate of liability risks from regulatory and litigious sources based on current knowledge. In this work, we present a conceptual framework for integrating estimated legal liabilities with EHS risks across nanomaterial life-cycle stages using empirical knowledge in the field, scientific and legal judgment, probabilistic risk assessment, and multicriteria decision analysis. Such estimates will provide investors and operators with a basis to compare different technologies and practices and will also inform regulatory and legislative bodies in determining standards that balance risks with technical advancement. We illustrate the framework through the hypothetical case of a manufacturer of nanoscale titanium dioxide and use the resulting expected legal costs to evaluate alternative risk-management actions.

Parental knowledge and adolescents' risk behaviors.

In this paper we study whether parental knowledge of adolescents' activities varies according to socio-demographic variables, and we analyze the possible association between parental knowledge patterns and certain risk behaviors among adolescents. A cross-sectional study was performed with representative samples of high-school students in Peru and El Salvador. A questionnaire assessed risk behaviors, as well as possible determinants, including parental knowledge. The questionnaire was answered by 6208 adolescents. We observed that the greater the degree of knowledge, the lower the frequency of risk behaviors among youth. The degree of knowledge was inversely associated with children's age, and we observed that being female was associated with a greater degree of parental knowledge. The study shows that parents' supervision criteria might be influenced by gender stereotypes, which would have a harmful effect on young males, as the lower degree of knowledge puts them at higher odds of risk behaviors.

To evaluate the effectiveness of an interactive, avatar based education application to improve knowledge of and response to heart attack symptoms in people who are at risk of a heart attack. Poor knowledge of heart attack symptoms is recognised as a significant barrier to timely medical treatment. Numerous studies have demonstrated that technology can assist in patient education to improve knowledge and self-care. A single-center, non-blinded, two parallel groups, pragmatic randomized controlled trial. Seventy patients will be recruited from the coronary care unit of a public hospital. Eligible participants will be randomised to either the usual care or the intervention group (usual care plus avatar-based heart attack education app). The primary outcome of this study is knowledge. Secondary outcomes include response to heart attack symptoms, health service use and satisfaction. Study participants will be followed-up for six months. This study will evaluate the avatar based education app as a method to deliver vital information to patients. Participants' knowledge of and response to heart attack symptoms, as well as their health service use, will be assessed to evaluate the intervention effectiveness.

To provide a quantitative assessment of patient knowledge about fertility and fertility preservation treatment options before the initial fertility preservation consultation at a university-based fertility preservation center. Prospective pilot survey containing 13 items assessing patient knowledge about fertility preservation, including the available treatment options and their requirements, success rates, and associated risks. University-based IVF center. Women aged 18 to 41 years with illnesses requiring treatments posing a serious threat to future fertility who were referred for fertility preservation consultation between April 2009 and June 2010. None. Knowledge score. Forty-one eligible patients were identified, and all completed surveys before their consultation. A knowledge score was generated for each patient with 1 point awarded for each correct answer. Overall, patients had poor previsit fertility preservation knowledge (mean score 5.9±2.7). Higher knowledge scores were correlated with personal experience with infertility and previous exposure to fertility preservation treatment information. There was no correlation between knowledge score and age, relationship status, pregnancy history, education, or income. Patients seen for fertility preservation consultation at our university-based center generally tend to be in their early 30s, white, well educated, and married. Previsit knowledge about fertility preservation treatment options was poor and did not correlate with age, education, and relationship status.

Exposure to chlorination disinfection by-products (CxDBPs) is prevalent in populations using chlorination-based methods to disinfect public water supplies. Multifaceted research has been directed for decades to identify, characterize, and understand the toxicology of these compounds, control and minimize their formation, and conduct epidemiologic studies related to exposure. Urinary bladder cancer has been the health risk most consistently associated with CxDBPs in epidemiologic studies. An international workshop was held to (1) discuss the qualitative strengths and limitations that inform the association between bladder cancer and CxDBPs in the context of possible causation, (2) identify knowledge gaps for this topic in relation to chlorine/chloramine-based disinfection practice(s) in the United States, and (3) assess the evidence for informing risk management. Epidemiological evidence linking exposures to CxDBPs in drinking water to human bladder cancer risk provides insight into causality. However, because of imprecise, inaccurate, or incomplete estimation of CxDBPs levels in epidemiologic studies, translation from hazard identification directly to risk management and regulatory policy for CxDBPs can be challenging. Quantitative risk estimates derived from toxicological risk assessment for CxDBPs currently cannot be reconciled with those from epidemiologic studies, notwithstanding the complexities involved, making regulatory interpretation difficult. Evidence presented here has both strengths and limitations that require additional studies to resolve and improve the understanding of exposure response relationships. Replication of epidemiologic findings in independent populations with further elaboration of exposure assessment is needed to strengthen the knowledge base needed to better inform effective regulatory approaches.

Prior data suggest that breast cancer patients accept significant toxicity for small benefit. It is unclear whether personalized estimations of risk or benefit likelihood that could be provided by biomarkers alter treatment decisions in the curative setting. A choice-based conjoint (CBC) survey was conducted in 417 HER2-negative breast cancer patients who received chemotherapy in the curative setting. The survey presented pairs of treatment choices derived from common taxane- and anthracycline-based regimens, varying in degree of benefit by risk of recurrence and in toxicity profile, including peripheral neuropathy (PN) and congestive heart failure (CHF). Hypothetical biomarkers shifting benefit and toxicity risk were modeled to determine whether this knowledge alters choice. Previously identified biomarkers were evaluated using this model. Based on CBC analysis, a non-anthracycline regimen was the most preferred. Patients with prior PN had a similar preference for a taxane regimen as those who were PN naïve, but more dramatically shifted preference away from taxanes when PN was described as severe/irreversible. When modeled after hypothetical biomarkers, as the likelihood of PN increased, the preference for taxane-containing regimens decreased; similarly, as the likelihood of CHF increased, the preference for anthracycline regimens decreased. When evaluating validated biomarkers for PN and CHF, this knowledge did alter regimen preference. Patients faced with multi-faceted decisions consider personal experience and perceived risk of recurrent disease. Biomarkers providing information on likelihood of toxicity risk do influence treatment choices, and patients may accept reduced benefit when faced with higher risk of toxicity in the curative setting.

The modern medical treatment of HIV with antiretroviral therapy (ART) has drastically reduced the morbidity and mortality in patients infected with this virus. ART has also been shown to reduce the transmission risk from individual patients as well as the spread of the infection at the population level. This position statement from the Public Health Agency of Sweden and the Swedish Reference Group for Antiviral Therapy is based on a workshop organized in the fall of 2012. It summarizes the latest research and knowledge on the risk of HIV transmission from patients on ART, with a focus on the risk of sexual transmission. The risk of transmission via shared injection equipment among intravenous drug users is also examined, as is the risk of mother-to-child transmission. Based on current knowledge, the risk of transmission through vaginal or anal intercourse involving the use of a condom has been judged to be minimal, provided that the person infected with HIV fulfils the criteria for effective ART. This probably also applies to unprotected intercourse, provided that no other sexually transmitted infections are present, although it is not currently possible to fully support this conclusion with direct scientific evidence. ART is judged to markedly reduce the risk of blood-borne transmission between people who share injection equipment. Finally, the risk of transmission from mother to child is very low, provided that ART is started well in advance of delivery. PMID:25073537

Assessing the risk of second malignancies after modern radiotherapy

Recent advances in radiotherapy have enabled the use of different types of particles, such as protons and heavy ions, as well as refinements to the treatment of tumours with standard sources (photons). However, the risk of second cancers arising in long-term survivors continues to be a problem. The long-term risks from treatments such as particle therapy have not yet been determined and are unlikely to become apparent for many years. Therefore, there is a need to develop risk assessments based on our current knowledge of radiation-induced carcinogenesis. PMID:21593785

2016-01-01

The current investigation aimed to assess levels of knowledge about risk factors for heart disease among midlife Israeli women, and to evaluate the relationship of knowledge to personal risk factors and vulnerability to heart disease. Face-to-face interviews with women aged 45-64 years were conducted during 2004-2006 within three population groups: long-term Jewish residents (LTR), immigrants from the former Soviet Union, and Arab women. The survey instrument included six knowledge statements relating to: the risk after menopause, family history, elevated cholesterol level, diabetes, obesity, and warning signs of a heart attack. The findings showed wide disparities in knowledge by educational level and between immigrants and LTR, after taking into account personal risk factors and education. Personal risk factors were not significantly related to the knowledge items, except for personal history of cardiovascular disease, which was associated with knowledge about "warning signs of a heart attack" and "family history." Women who perceived themselves as more vulnerable to heart disease were more likely to identify several risk factors correctly. These findings stress the need to increase knowledge about heart disease, especially among less educated and minority women, and to emphasize the risk of patients' personal status by health providers.

Effects of Knowledge on Attitude Formation and Change Toward Genetically Modified Foods.

In three waves, this study investigates the impact of risk and benefit knowledge on attitude formation toward genetically modified (GM) foods as well as the moderating effect of knowledge level on attitude change caused by receiving information. The data in Wave 1 (N = 561) demonstrate that both benefit and risk knowledge either directly contribute to attitude formation or indirectly affect attitudes through the mediating roles of benefit and risk perceptions. Overall, benefit and risk knowledge affect consumer attitudes positively and negatively, respectively. In Wave 2, 486 participants from Wave 1 were provided with information about GM foods, and their attitudes were assessed. Three weeks later, 433 of these participants again reported their attitudes. The results indicate that compared with the benefit and mixed information, risk information has a greater and longer lasting impact on attitude change, which results in lower acceptance of GM foods. Furthermore, risk information more strongly influences participants with a higher knowledge level. The moderating effect of knowledge on attitude change may result from these participants' better understanding of and greater trust in the information. These findings highlight the important role of knowledge in attitude formation and attitude change toward GM foods as well as the necessity of considering the determinants of attitude formation in attitude change studies. © 2014 Society for Risk Analysis.

For health scientists, knowledge translation refers to the process of facilitating uptake of knowledge into clinical practice or decision making. Since high-quality clinical research that is not applied cannot improve outcomes, knowledge translation is critical for realizing the value and potential for all types of health research. Knowledge translation is particularly relevant for areas within health care where gaps in care are known to exist, which is the case for some areas of management for people with chronic kidney disease (CKD), including assessment of proteinuria. Given that proteinuria is a key marker of cardiovascular and renal risk, forthcoming international practice guidelines will recommend including proteinuria within staging systems for CKD. While this revised staging system will facilitate identification of patients at higher risk for progression of CKD and mortality who benefit from intervention, strategies to ensure its appropriate uptake will be particularly important. This article describes key elements of effective knowledge translation strategies based on the knowledge-to-action cycle framework and describes options for effective knowledge translation interventions related to the new CKD guidelines, focusing on recommendations related to assessment for proteinuria specifically. The article also presents findings from a multidisciplinary meeting aimed at developing knowledge translation intervention strategies, with input from key stakeholders (researchers, knowledge users, decision makers and collaborators), to facilitate implementation of this guideline. These considerations are relevant for dissemination and implementation of guidelines on other topics and in other clinical settings.

Our aim was to develop and test an educational program to support well-informed decision making among patients and their social network regarding living donor kidney transplantation (LDKT). One hundred sixty-three patients who were unable to find a living donor were randomized to standard care or standard care plus home-based education. In the education condition, patients and members of their social network participated in home-based educational meetings and discussed renal replacement therapy options. Patients and invitees completed pre-post self-report questionnaires measuring knowledge, risk perception, communication, self-efficacy and subjective norm. LDKT activities were observed for 6 months postintervention. Patients in the experimental group showed significantly more improvements in knowledge (p < 0.001) and communication (p = 0.012) compared with the control group. The invitees showed pre-post increases in knowledge (p < 0.001), attitude toward discussing renal replacement therapies (p = 0.020), attitude toward donating a kidney (p = 0.023) and willingness to donate a kidney (p = 0.039) and a decrease in risk perception (p = 0.003). Finally, there were significantly more inquiries (29/39 vs. 13/41, p < 0.001), evaluations (25/39 vs. 7/41, p < 0.001) and actual LDKTs (17/39 vs. 4/41, p = 0.003) in the experimental group compared with the control group. Home-based family education supports well-informed decision making and promotes access to LDKT. © Copyright 2014 The American Society of Transplantation and the American Society of Transplant Surgeons.

Map Your Hazards! - an Interdisciplinary, Place-Based Educational Approach to Assessing Natural Hazards, Social Vulnerability, Risk and Risk Perception.

'Map your Hazards' is an educational module developed within the NSF Interdisciplinary Teaching about Earth for a Sustainable Future program (InTeGrate). The module engages students in place-based explorations of natural hazards, social vulnerability, and the perception of natural hazards and risk. Students integrate geoscience and social science methodologies to (1) identify and assess hazards, vulnerability and risk within their communities; (2) distribute, collect and evaluate survey data (designed by authors) on the knowledge, risk perception and preparedness within their social networks; and (3) deliver a PPT presentation to local stakeholders detailing their findings and recommendations for development of a prepared, resilient community. 'Map your Hazards' underwent four rigorous assessments by a team of geoscience educators and external review before being piloted in our classrooms. The module was piloted in a 300-level 'Volcanoes and Society' course at Boise State University, a 300-level 'Environmental Sociology' course at Central Washington University, and a 100-level 'Natural Disasters and Environmental Geology' course at the College of Western Idaho. In all courses students reported a fascination with learning about the hazards around them and identifying the high risk areas in their communities. They were also surprised at the low level of knowledge, inaccurate risk perception and lack of preparedness of their social networks. This successful approach to engaging students in an interdisciplinary, place-based learning environment also has the broad implications of raising awareness of natural hazards (survey participants are provided links to local hazard and preparedness information). The data and preparedness suggestions can be shared with local emergency managers, who are encouraged to attend the student's final presentations. All module materials are published at serc.carleton.edu/integrate/ and are appropriate to a wide range of classrooms.

Risk modification through behavior change is critical for primary and secondary stroke prevention. Theories of health behavior identify perceived risk as an important component to facilitate behavior change; however, little is known about perceived risk of vascular events among stroke survivors. The SWIFT (Stroke Warning Information and Faster Treatment) study includes a prospective population-based ethnically diverse cohort of ischemic stroke and transient ischemic attack survivors. We investigate the baseline relationship between demographics, health beliefs, and knowledge on risk perception. Regression models examined predictors of inaccurate perception. Only 20% accurately estimated risk, 10% of the participants underestimated risk, and 70% of the 817 study participants significantly overestimated their risk for a recurrent stroke. The mean perceived likelihood of recurrent ischemic stroke in the next 10 years was 51 ± 7%. We found no significant differences by race-ethnicity with regard to accurate estimation of risk. Inaccurate estimation of risk was associated with attitudes and beliefs [worry (p < 0.04), fatalism (p < 0.07)] and memory problems (p < 0.01), but not history or knowledge of vascular risk factors. This paper provides a unique perspective on how factors such as belief systems influence risk perception in a diverse population at high stroke risk. There is a need for future research on how risk perception can inform primary and secondary stroke prevention. Copyright © 2011 S. Karger AG, Basel.

Knowledge and Health Belief Attitudes of Oral Cancer and Its Screening Among At-Risk Southern Thai Muslims.

Oral cancer is one of the leading cancers in Thailand; southern Thai Muslims seem to have a longer delay in attending treatment for oral cancer than Buddhists in the same area. Visual screenings of high-risk populations have been suggested to be an effective prevention method. This study assessed oral cancer knowledge and belief attitudes influencing oral cancer screening in Thai Muslim high-risk groups. Twelve semi-structured in-depth interviews and the focus group discussion were conducted based on the health belief model. Stratified purposeful sampling was used to recruit the participants. Inclusion criteria were those who practiced the risk habits for oral cancer and were 40 years of age or older, smokers (20+ cigarettes per day for at least 20 years) and/or betel quid chewers (10+ times per day for at least 10 years). Participants lacked knowledge about oral cancer in terms of signs and symptoms and predisposing factors. This influenced misleading belief attitudes concerning susceptibility of oral cancer, barriers, and their self-efficacy to have oral cancer screening examinations. Betel quid chewing was not regarded as a risk habit but as having a protective role against the disease. Perceived susceptibility was also seen by some to be dependent upon Allah's will. Traditional medication was mentioned as a preferred alternative to modern treatment. The latter was believed by some to be the cause of death for cancer patients. Interventions to promote oral cancer knowledge and right belief attitudes for oral cancer screening are clearly indicated.

Web based collaborative decision making in flood risk management

Stakeholder participation in the development of flood risk management (FRM) plans is essential since stakeholders often have a better understanding or knowledge of the potentials and limitation of their local area. Moreover, a participatory approach also creates trust amongst stakeholders, leading to a successful implementation of measures. Stakeholder participation however has its challenges and potential pitfalls that could lead to its premature termination. Such challenges and pitfalls are the limitation of financial resources, stakeholders' spatial distribution and their interest to participate. Different type of participation in FRM may encounter diverse challenges. These types of participation in FRM can be classified into (1) Information and knowledge sharing (IKS), (2) Consultative participation (CP) or (3) Collaborative decision making (CDM)- the most challenging type of participation. An innovative approach to address these challenges and potential pitfalls is a web-based mobile or computer-aided environment for stakeholder participation. This enhances the remote interaction between participating entities such as stakeholders. This paper presents a developed framework and an implementation of CDM web based environment for the Alster catchment (Hamburg, Germany) and Cranbrook catchment (London, UK). The CDM framework consists of two main stages: (1) Collaborative modelling and (2) Participatory decision making. This paper also highlights the stakeholder analyses, modelling approach and application of General Public License (GPL) technologies in developing the web-based environments. Actual test and evaluation of the environments was through series of stakeholders workshops. The overall results based from stakeholders' evaluation shows that web-based environments can address the challenges and potential pitfalls in stakeholder participation and it enhances participation in flood risk management. The web-based environment was developed within the DIANE-CM project (Decentralised Integrated Analysis and Enhancement of Awareness through Collaborative Modelling and Management of Flood Risk) of the 2nd ERANET CRUE funding initiative.

The purpose of this review is to provide educators with the knowledge and tools to utilize plant-based nutrition education as an intervention for type 2 diabetes. Scientific support for the efficacy, acceptability, and nutritional adequacy of a plant-based diet for people with type 2 diabetes is presented, and practical considerations such as medication adjustment and risk of hypoglycemia are reviewed. Plant-based meal planning is an acceptable and effective strategy that educators can use to improve diabetes management and reduce risk of complications. Studies show that dietary changes that are effective for reducing cardiac risk may also be helpful for management of type 2 diabetes. A low-fat, plant-based diet reduces body weight and improves glycemic control, and has been shown to be remarkably well accepted by patients.

There is growing evidence that inclusion of genetic information about known common susceptibility variants may enable population risk-stratification and personalized prevention for common diseases including cancer. This would require the inclusion of genetic testing as an integral part of individual risk assessment of an asymptomatic individual. Front line health professionals would be expected to interact with and assist asymptomatic individuals through the risk stratification process. In that case, additional knowledge and skills may be needed. Current guidelines and frameworks for genetic competencies of non-specialist health professionals place an emphasis on rare inherited genetic diseases. For common diseases, health professionals do use risk assessment tools but such tools currently do not assess genetic susceptibility of individuals. In this article, we compare the skills and knowledge needed by non-genetic health professionals, if risk-stratified prevention is implemented, with existing competence recommendations from the UK, USA and Europe, in order to assess the gaps in current competences. We found that health professionals would benefit from understanding the contribution of common genetic variations in disease risk, the rationale for a risk-stratified prevention pathway, and the implications of using genomic information in risk-assessment and risk management of asymptomatic individuals for common disease prevention.

2011-01-01

A comprehensive approach for providing behavioral health services to youth is becoming increasingly emphasized (IOM, 2009). Latino youth are at increased risk for substance abuse, mental health concerns, unsafe sexual practices and HIV (Prado et al., 2006), and these outcomes have been empirically connected to individual, family and community-based stress (IOM, 2009). Despite this knowledge, there is a lack of evidence-based approaches that target these negative outcomes by reducing stress in Latino families in a culturally relevant manner (Cervantes, Kappos, Duenas & Arellano, 2003). The current study examined the use of research-based strategies for reducing multiple risk behaviors in a predominantly Mexican American sample of families. Through a modular approach, participants engaged in a psycho-educational curriculum to enhance communication and psychosocial coping, increase substance abuse and HIV knowledge and perception of harm, and improve school behavior. Over 12 sessions, the curriculum aimed to achieve these outcomes through an overall decrease in family and community-based stress by focusing on acculturative stress. Findings indicate that communication and perception of substance use harm were significantly enhanced, while social norms regarding sexual behavior, HIV anxiety and past use of marijuana and other illegal drugs were significantly reduced. While many of measures were reliable (α > .80), further changes are necessary to improve the accuracy of future studies. Despite these limitations, Familia Adelante improves many areas of participant’s family life, and points toward the feasibility of multi-risk reduction behavioral health prevention approaches.

Osteoporosis-related life habits and knowledge about osteoporosis among women in El Salvador: A cross-sectional study

PubMed Central

Hernandez-Rauda, Roberto; Martinez-Garcia, Sandra

2004-01-01

Background Osteoporosis is a systemic skeletal disorder, characterized by reduced bone mass, deterioration of bone structure, increased bone fragility, and increased fracture risk. It is more frequent to find among women than men at a 4:1 ratio. Evidence suggests that to adopt changes on some life habits can prevent or delay development of osteoporosis. Several osteoporosis-risk factors have been confirmed in the US and western Europe, but in El Salvador there are neither reliable epidemiological statistics about this skeletal disorder nor studies addressing osteoporosis-risk factors in women. The aim of this study was to determinate the extent of osteoporosis knowledge, the levels of both daily calcium intake and weight-bearing physical activity, and the influence of several osteoporosis-risk factors on these variables in three age groups of Salvadorean women. Methods In this exploratory cross-sectional study, an osteoporosis knowledge assessment questionnaire incluiding a food frequency and a physical activity record section were used to collect data and it was delivered through a face-to-face interview. A convenience sample (n = 197) comprised of three groups of women aged 25–35 years, 36–49 years, and over 49 years was taken. Among-group comparisons of means were analyzed by two-way ANOVA. To determinate the overall influence of osteoporosis-risk factors, the multivariate analysis was used. Results Study results indicated that better educated women had more knowledge about osteoporosis than women with a low education level, regardless of age, even though this knowledge was rather fair. Older women got more weight-bearing physical activity at home and less at place of employment than reported by the younger women; however, neither group performed sufficient high-intensity WBPA to improve bone mass. Regardless of age, the most women consumed 60% or less than the Dietary Reference Intake of calcium and depend on household income, lactose intolerance and coffee rather than milk consumption. Conclusion In summary, the majority of women in this study have modest knowledge on osteoporosis. The knowledge base is not linked to preventive health habits, including sufficient calcium intake and performance of weight-bearing physical activities. They are thus at increased risk for low bone mass. PMID:15329150

Community stroke awareness initiatives have traditionally been used to expand knowledge of stroke signs and risk factors to high-risk adult populations. Here, we use a novel unfettered, visual art-based approach for an elementary school initiative to raise stroke awareness. Seventh graders in a middle school art class received stroke awareness training during the course of the 2015 to 2016 school year through their teacher in the visual arts class. In turn, they used this training to develop their own artistic interpretations of key stroke awareness concepts via project-based learning and then present their projects to raise awareness about stroke. We evaluated our predata and postdata to determine whether the visual art school-based stroke intervention was effective in both educating students about stroke and enabling them to effectively disseminate this information to parents and other adults in their community. The pretest evaluation indicates a fair or good knowledge about stroke, and no student indicated an "outstanding" or "excellent" knowledge. The posttest evaluation indicated a higher degree of stroke awareness because students were rated as having an "outstanding," "excellent," or "very good" performance especially in the ability to translate knowledge of stroke awareness lessons learned in their art class into a well-articulated stroke-related project and presentation. Pearson χ test reveals significant difference (P < .001) between the pretest and posttest evaluations. Our results indicate that our school-based stroke intervention was effective in both educating students about stroke and enabling them to effectively disseminate this information to parents and other adults in their community. The use of a visual art teacher to lead the educational component in the intervention indicates that expertise in neurology or stroke is not necessary to facilitate understanding of stroke and highlights the importance of creativeness in stroke education for children.

Background and purpose The public knowledge of diabetes is important for prevention of disease. This study aimed to evaluate knowledge of diabetes, risk factors, and the common warning signs of diabetes and complications among community participants in a rural Karen ethnic community. Methods Participants were asked to answer a questionnaire regarding their knowledge of diabetes. Fasting blood glucose testing, blood pressure measurement, and body mass index (BMI) assessment were provided to the participants. The study was conducted at Thasongyang district, Tak province, Thailand. Results A total of 299 Karen rural residents were included in the study. The median age was 45 years and median fasting blood glucose was 88 mg/dL. The response rate to the questionnaires was 91.97%. Half of the participants knew diabetes is a noncommunicable disease needing lifelong treatment. Overall, one-third of the community participants could correctly answer the knowledge assessment questions regarding risk factors and common features of diabetes. whereas the other two-thirds either gave a wrong answer or were “not sure”. Female participants had poorer diabetes knowledge than the males. Conclusion The public knowledge of diabetes, as represented by this sample of the Karen ethic community, is alarmingly low. There is significant gender difference in knowledge level. Culturally tailored and gender-sensitive diabetes health education interventions are urgently needed in this minority ethnic community.

Breast cancer is the most common cancer among women in Malaysia, about one in 19 women being at risk. This study aimed to investigate knowledge and practice of breast self-examination (BSE), as well as knowledge of risk factors for breast cancer amongst female adolescents in Malaysia. Subsequently, relationships between demographic characteristics and knowledge level of BSE, risk factors for breast cancer and BSE practice were assessed. A descriptive, cross sectional survey was conducted using a sample of 500 Malaysian adolescents from the age of 15 to 19 years. A self-administered questionnaire was used to gather socio- demographic characteristics, knowledge of BSE, knowledge of risk factors for breast cancer and BSE practices. The findings of this study indicated that female adolescents in Malaysia demonstrated an inadequate knowledge level of BSE and risk factors for breast cancer. Only 27.8% of female adolescents performed BSE regularly. BSE practice, knowledge of BSE and knowledge of risk factors for breast cancer showed significant positive relationships. The study highlighted the importance of planning and implementing breast health education programs for female students in secondary schools in Malaysia. It will also provide the health care providers an avenue to stress on the importance of imparting breast health education to adolescents.

Risk-based Process Development of Biosimilars as Part of the Quality by Design Paradigm.

PubMed

Zalai, Dénes; Dietzsch, Christian; Herwig, Christoph

2013-01-01

In the last few years, several quality by design (QbD) studies demonstrated the benefit of systematic approaches for biopharmaceutical development. However, only very few studies identified biosimilars as a special case of product development. The targeted quality profile of biosimilars is strictly defined by the originator's product characteristic. Moreover, the major source of prior knowledge is the experience with the originator product itself. Processing this information in biosimilar development has a major effect on risk management and process development strategies. The main objective of this contribution is to demonstrate how risk management can facilitate the implementation of QbD in early-stage product development with special emphasis on fitting the reported approaches to biosimilars. Risk assessments were highlighted as important tools to integrate prior knowledge in biosimilar development. The risk assessment process as suggested by the International Conference on Harmonization (ICH Q9) was reviewed and three elements were identified to play a key role in targeted risk assessment approaches: proper understanding of target linkage, risk assessment tool compliance, and criticality threshold value. Adjusting these steps to biosimilar applications helped to address some unique challenges of these products such as a strictly defined quality profile or a lack of process knowledge. This contribution demonstrates the need for tailored risk management approaches for the risk-based development of biosimilars and provides novel tools for the integration of additional knowledge available for these products. The pharmaceutical industry is facing challenges such as profit loss and price competition. Companies are forced to rationalize business models and to cut costs in development as well as manufacturing. These trends recently hinder the implementation of any concepts that do not offer certain financial benefit or promise a long return of investment. Quality by design (QbD) is a concept that is currently struggling for more acceptance from the side of the pharmaceutical industry. To achieve this, the major goals of QbD have to be revisited and QbD tools have to be subsequently developed. This contribution offers an example as to how implement risk management in early-stage biosimilar development as part of the QbD concept. The main goal was to go beyond the conventional QbD workflow and to adjust risk management to the challenges of biosimilar products. Accordingly, instead of using methods like failure mode and effects analysis, recommendations of the ICH Q9 guideline were reviewed and put into practice by creating tailored risk assessment tools. The novelty of this contribution is to report those tailored tools ready-to-use for early bioprocess development of biosimilars along QbD principles.

[Knowledge and attitude towards diabetes mellitus in Argentina].

PubMed

Rodríguez, Martín; Puchulu, Félix

2015-01-01

A population survey was conducted in 9 provinces of Argentina in 2012 aimed at determining the level of knowledge of diabetes mellitus and the risk of developing the disease. This was a cross-sectional study based on the general population and including men and women aged 18-70 years from all socioeconomic backgrounds. Results showed that 30.5% of participants without diabetes mellitus were at risk of developing the disease. Fifty-nine percent of participants had a body mass index = 25 kg/m2. Forty-nine percent did less than 30 minutes of daily physical activity. Only 34% of the population ate fruits and vegetables every day. Ninety-eight percent of participants had once heard of diabetes, and 67% defined it as a severe or very severe disease. In view of the findings resulting from this survey, healthcare services are expected to improve prevention and effective control of cardiovascular risk factors as well as to enhance preventive actions in order to encourage the adoption of healthier lifestyles from an earlier age and to achieve greater knowledge not only among patients living with diabetes, but also within the general population.

Health professionals, particularly nurses, continue to struggle with the expanding role of genetics information in the care of their patients. This paper describes an evaluation study of the effectiveness of a hybrid basic genetics course for healthcare professionals combining web-based learning with traditional face-to-face instructional techniques. A multidisciplinary group from the National Institutes of Health (NIH) created "Basic Genetics Education for Healthcare Providers" (BGEHCP). This program combined 7 web-based self-education modules with monthly traditional face-to-face lectures by genetics experts. The course was pilot tested by 186 healthcare providers from various disciplines with 69% (n=129) of the class registrants enrolling in a pre-post evaluation trial. Outcome measures included critical thinking knowledge items and a Web-based Learning Environment Inventory (WEBLEI). Results indicated a significant (p<0.001) change in knowledge scores. WEBLEI scores indicated program effectiveness particularly in the area of convenience, access and the course structure and design. Although significant increases in overall knowledge scores were achieved, scores in content areas surrounding genetic risk identification and ethical issues regarding genetic testing reflected continued gaps in knowledge. Web-based genetics education may help overcome genetics knowledge deficits by providing access for health professionals with diverse schedules in a variety of national and international settings.

Interactions of metal-based engineered nanoparticles with aquatic higher plants: A review of the state of current knowledge.

PubMed

Thwala, Melusi; Klaine, Stephen J; Musee, Ndeke

2016-07-01

The rising potential for the release of engineered nanoparticles (ENPs) into aquatic environments requires evaluation of risks to protect ecological health. The present review examines knowledge pertaining to the interactions of metal-based ENPs with aquatic higher plants, identifies information gaps, and raises considerations for future research to advance knowledge on the subject. The discussion focuses on ENPs' bioaccessibility; uptake, adsorption, translocation, and bioaccumulation; and toxicity effects on aquatic higher plants. An information deficit surrounds the uptake of ENPs and associated dynamics, because the influence of ENP characteristics and water quality conditions has not been well documented. Dissolution appears to be a key mechanism driving bioaccumulation of ENPs, whereas nanoparticulates often adsorb to plant surfaces with minimal internalization. However, few reports document the internalization of ENPs by plants; thus, the role of nanoparticulates' internalization in bioaccumulation and toxicity remains unclear, requiring further investigation. The toxicities of metal-based ENPs mainly have been associated with dissolution as a predominant mechanism, although nano toxicity has also been reported. To advance knowledge in this domain, future investigations need to integrate the influence of ENP characteristics and water physicochemical parameters, as their interplay determines ENP bioaccessibility and influences their risk to health of aquatic higher plants. Furthermore, harmonization of test protocols is recommended for fast tracking the generation of comparable data. Environ Toxicol Chem 2016;35:1677-1694. © 2016 SETAC. © 2016 SETAC.

2017-02-01

Parental knowledge about adolescents' activities is an identified protective factor in terms of adolescent adjustment. While research on parental knowledge has focused on adolescents' offline behavior, there is little empirical understanding of parental knowledge about adolescents' online behavior. This study investigates parental knowledge about adolescents' online activities and experiences with online risks, as well as the correlates of such knowledge. Building on former research, open communication and knowledge-generating monitoring practices are investigated as potential correlates of parental knowledge. Use is made of triadic data, relying on reports from children aged 13 to 18, mothers and fathers within the same family (N = 357 families; 54.9 % female adolescents). The results showed that parents have little knowledge about the occurrence of online risks and their children's online activities. While mothers did not have more accurate knowledge compared to fathers, they did perceive themselves to be more knowledgeable than fathers. Associations between parental knowledge and hypothesized correlates were tested by means of one-way ANOVA tests and stepwise logistic regression models. Limited evidence was found for associations with parents' accurate knowledge about the occurrence of online risks. Engagement in knowledge-generating monitoring practices was linked to mothers and fathers' self-perceived knowledge about their children's online activities. For mothers, open communication with the child was linked to self-perceived knowledge. The findings suggest that parents need to be more aware of the possibility that online risks might occur and that more research needs to be done in order to understand what parents can do to improve their accurate knowledge.

To examine the reach, efficacy, and adoption of The Bigger Picture, a type 2 diabetes (T2DM) social marketing campaign that uses spoken-word public service announcements (PSAs) to teach youth about socioenvironmental conditions influencing T2DM risk. A nonexperimental pilot dissemination evaluation through high school assemblies and a Web-based platform were used. The study took place in San Francisco Bay Area high schools during 2013. In the study, 885 students were sampled from 13 high schools. A 1-hour assembly provided data, poet performances, video PSAs, and Web-based platform information. A Web-based platform featured the campaign Web site and social media. Student surveys preassembly and postassembly (knowledge, attitudes), assembly observations, school demographics, counts of Web-based utilization, and adoption were measured. Descriptive statistics, McNemar's χ 2 test, and mixed modeling accounting for clustering were used to analyze data. The campaign included 23 youth poet-created PSAs. It reached >2400 students (93% self-identified non-white) through school assemblies and has garnered >1,000,000 views of Web-based video PSAs. School participants demonstrated increased short-term knowledge of T2DM as preventable, with risk driven by socioenvironmental factors (34% preassembly identified environmental causes as influencing T2DM risk compared to 83% postassembly), and perceived greater personal salience of T2DM risk reduction (p < .001 for all). The campaign has been adopted by regional public health departments. The Bigger Picture campaign showed its potential for reaching and engaging diverse youth. Campaign messaging is being adopted by stakeholders.

The aim of this study was to assess the knowledge about the risk of infertility in cancer patients after treatment, and the options for fertility preservation based on a survey carried out during the 2013 Pink October campaign. This survey was carried out during the 2013 Pink October event in the most important public park of São Paulo, Brazil. Approximately 900 people expressed interest in learning about breast cancer prevention and fertility preservation by participating in workshops, and 242 people filled out a questionnaire. Most of the respondents (78.5%) were women, and one-fourth (25%) had at least one relative with gynecological cancer. Among women over 40 years of age, 86.3% had been screened for breast cancer at some point. However, few participants (34.0%) were aware that cancer treatment can lead to infertility or had heard about fertility preservation options (22.0%). Having a relative with cancer did not influence their knowledge about fertility preservation (22.4% versus 21.3%; p=0.864). However, a higher educational level was significantly associated with more knowledge about the effects of cancer on fertility and options for fertility preservation. The majority of participants did not have knowledge about the impact of oncologic treatment on fertility and did not know that there are options to preserve fertility in cancer patients. Awareness of infertility risk factors is an essential first step to safeguard future fertility, and therefore, more educational initiatives are needed to spread knowledge about oncofertility.

A prototype system for perinatal knowledge engineering using an artificial intelligence tool.

Though several perinatal expert systems are extant, the use of artificial intelligence has, as yet, had minimal impact in medical computing. In this evaluation of the potential of AI techniques in the development of a computer based "Perinatal Consultant," a "top down" approach to the development of a perinatal knowledge base was taken, using as a source for such a knowledge base a 30-page manuscript of a chapter concerning high risk pregnancy. The UNIX utility "style" was used to parse sentences and obtain key words and phrases, both as part of a natural language interface and to identify key perinatal concepts. Compared with the "gold standard" of sentences containing key facts as chosen by the experts, a semiautomated method using a nonmedical speller to identify key words and phrases in context functioned with a sensitivity of 79%, i.e., approximately 8 in 10 key sentences were detected as the basis for PROLOG, rules and facts for the knowledge base. These encouraging results suggest that functional perinatal expert systems may well be expedited by using programming utilities in conjunction with AI tools and published literature.

Opening our eyes to Global Health; a philosophy of universal values.

PubMed

Wass, Val

2015-12-01

Globalization is advancing at a pace. As we strive to introduce 'Global Health' into clinical curricula we risk fundamental misunderstandings unless we clearly define what we aim to achieve. Clinicians must be prepared for a life time of uncertainty, change and challenge. The fluctuating world arena will undoubtedly impact on their future work in ways we cannot predict. Population migration, climate change and shifts in cultural dominance are already at play. Global health risks being translated through the eyes of Western ideology as disease-based curricula focused paternalistically on 'helping' the developing world. We must not lack humility to open eyes to learning within the context of increasingly diverse environments and patient populations. Global health is as 'local' as it is 'international'. It should be viewed, I argue, as a philosophy based on the values and expectations found within ourselves and our communities. Responding to globalization lies not only in knowledge but embraces human rights, justice and, most importantly, self-awareness. Knowledge is more easily translated into curriculum objectives. We risk letting future clinicians and their patients down if we ignore the other universal values.

White-Heisel, Regina; Canfield, James P; Young-Hughes, Sadie

Perceiving imminent safe patient handling and movement (SPH&M) dangers may reduce musculoskeletal (MSK) injuries for nurses in the workplace. The purpose of this study is to develop and validate the 17-item Safe Patient Handling Perception Scale (SPHPS) as an evaluation instrument assessing perceptual risk of MSK injury based on SPH&M knowledge, practice, and resource accessibility in the workplace. Data were collected from a convenience sample (N = 117) of nursing employees at a Veteran Affairs Medical Center. Factor analysis identified three factors: knowledge, practice, and accessibility. The SPHPS demonstrated high levels of reliability, supported by acceptable alpha scores (SPHM knowledge [α = .866], SPHM practices [α = .901], and access to SPHM resources [α = .855]), in addition to the relatively low standard error of measurement scores (SEM). The study outcomes suggest that the SPHPS is a valid and reliable tool that can measure participants' perceived risk factors for MSK injuries.

Risk perception is judgment that people make about the characteristics and severity of risks, in last few years risk perception studies focused on provide cognitive elements to communication experts responsible in order to design citizenship information and awareness appropriate strategies. Several authors in order to determine natural hazards risk (Seismic, landslides, cyclones, flood, Volcanic) perception used questionnaires as tool for providing reliable quantitative data and permitting comparison the results with those of similar surveys. In Italy, risk perception studies based on surveys, were also carried out in order to investigate on national importance Natural risk, in particular on Somma-Vesuvio and Phlegrean Fields volcanic Risks, but lacked risk perception studies on local situation distributed on whole national territory. National importance natural hazard were frequently reported by national mass media and there were debate about emergencies civil protection plans, otherwise could be difficult to obtain information on bonded and regional nature natural hazard which were diffuses along National territory. In fact, Italian peninsula was a younger geological area subjected to endogenous phenomena (volcanoes, earthquake) and exogenous phenomena which determine land evolution and natural hazard (landslide, coastal erosion, hydrogeological instability, sinkhole) for population. For this reason we decided to investigate on natural risks perception in different Italian place were natural hazard were taken place but not reported from mass media, as were only local relevant or historical event. We carried out surveys in different Italian place interested by different types of natural Hazard (landslide, coastal erosion, hydrogeological instability, sinkhole, volcanic phenomena and earthquake) and compared results, in order to understand population perception level, awareness and civil protection exercises preparation. Our findings support that risks communication have to be based on citizen knowledge and conscious in natural hazards. In fact, informed citizen could participate actively in decision in urban development planning and accept positively legislation and regulation introduced to avoid natural risks. The study has gone some way towards enhancing understanding in citizens conscious in natural risks and allow us to say that communication on natural risks could not be based only in transferring emergency behavior to citizens but also allow people to improve their knowledge in landscape evolution in order to assume aware environmental behavior.

Microbiological risk assessment for personal care products.

Regulatory decisions regarding microbiological safety of cosmetics and personal care products are primarily hazard-based, where the presence of a potential pathogen determines decision-making. This contrasts with the Food industry where it is a commonplace to use a risk-based approach for ensuring microbiological safety. A risk-based approach allows consideration of the degree of exposure to assess unacceptable health risks. As there can be a number of advantages in using a risk-based approach to safety, this study explores the Codex Alimentarius (Codex) four-step Microbiological Risk Assessment (MRA) framework frequently used in the Food industry and examines how it can be applied to the safety assessment of personal care products. The hazard identification and hazard characterization steps (one and two) of the Codex MRA framework consider the main microorganisms of concern. These are addressed by reviewing the current industry guidelines for objectionable organisms and analysing reports of contaminated products notified by government agencies over a recent 5-year period, together with examples of reported outbreaks. Data related to estimation of exposure (step three) are discussed, and examples of possible calculations and references are included. The fourth step, performed by the risk assessor (risk characterization), is specific to each assessment and brings together the information from the first three steps to assess the risk. Although there are very few documented uses of the MRA approach for personal care products, this study illustrates that it is a practicable and sound approach for producing products that are safe by design. It can be helpful in the context of designing products and processes going to market and with setting of microbiological specifications. Additionally, it can be applied reactively to facilitate decision-making when contaminated products are released on to the marketplace. Currently, the knowledge available may only allow a qualitative or semi-quantitative rather than fully quantitative risk assessment, but an added benefit is that the disciplined structuring of available knowledge enables clear identification of gaps to target resources and if appropriate, instigate data generation. © 2016 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

Methodology Analytical cross-sectional study. 720 health workers from Santiago answered a survey about HIV/AIDS that included: knowledge level (appropriate, inappropriate), occupational risk (with or without risk), and control variables (age, gender, health center, education and marital status). Descriptive and association analysis were performed. Odds Ratio (OR) was estimated through simple and multiple regressions logistics. Results 58.7% of the participants reported HIV occupational risk. 63.8% of the participants from the exposed group reported an appropriate level of knowledge, versus 36.1% of the non-exposed group (Adjusted OR of 3.1, IC95%OR: 2.0-4.8, p<0.0001). Technicians and cleaning staff reported a lower proportion of appropriate level of knowledge compared to the employees with college education (p<0.0001). Conclusion The level of HIV/AID occupational risk is directly associated with the level of knowledge of the disease. PMID:25284913

The aim of this study was to determine if polysyllable accuracy in preschoolers with speech sound disorders (SSD) was related to known predictors of later literacy development: phonological processing, receptive vocabulary, and print knowledge. Polysyllables-words of three or more syllables-are important to consider because unlike monosyllables, polysyllables have been associated with phonological processing and literacy difficulties in school-aged children. They therefore have the potential to help identify preschoolers most at risk of future literacy difficulties. Participants were 93 preschool children with SSD from the Sound Start Study. Participants completed the Polysyllable Preschool Test (Baker, 2013) as well as phonological processing, receptive vocabulary, and print knowledge tasks. Cluster analysis was completed, and 2 clusters were identified: low polysyllable accuracy and moderate polysyllable accuracy. The clusters were significantly different based on 2 measures of phonological awareness and measures of receptive vocabulary, rapid naming, and digit span. The clusters were not significantly different on sound matching accuracy or letter, sound, or print concept knowledge. The participants' poor performance on print knowledge tasks suggested that as a group, they were at risk of literacy difficulties but that there was a cluster of participants at greater risk-those with both low polysyllable accuracy and poor phonological processing.

To evaluate the impact of a tuberculosis (TB) educational intervention (EI) on change in adolescent student knowledge and participation in a TB prevention program. From 2/2013-5/2015, students from 2 high schools in Houston, TX participated. The 25-min EI discussed TB bacteriology, epidemiology, symptoms, and indications for TB testing/treatment. Students completed pre- and post-quizzes. Immediately after the EI, students were invited to participate in voluntary TB risk-factor screening, testing and treatment. At 6 months, focus groups were conducted. 895 students attended the EI. 827 students (92%) completed the EI quizzes. Knowledge improved by 12% (pre: 70%; post: 82%, p<0.001); 78% shared their TB knowledge. Following the EI, 671/827 (81%) enrolled in a TB prevention program. Focus groups indicated that the EI stimulated student learning about TB and increased their willingness to participate. A brief, one-time, TB EI is an effective method to encourage adolescents to learn about TB and motivate their uptake of TB risk-factor screening, testing and treatment. Similar EIs should accompany TB prevention programs targeting adolescents. The study's procedures could be considered for incorporation into school-based TB prevention programs to improve the identification, testing and treatment of adolescents at risk for TB.

Peterson, Barry

2009-01-01

The Sensorimotor Risk Standing Review Panel (SRP) met at the NASA Johnson Space Center on October 4-6, 2009 to discuss the areas of future research targeted by the Human Health Countermeasures (HHC) Element of the Human Research Program (HRP). Using evidence-based knowledge as a background for risks, NASA had identified gaps in knowledge to address those risks. Ongoing and proposed tasks were presented to address the gaps. The charge to the Sensorimotor Risk SRP was to review the gaps, evaluate whether the tasks addressed these gaps and to make recommendations to NASA s HRP Science Management Office regarding the SRP's review. The SRP was requested to evaluate the practicality of the proposed efforts in light of the realistic demands placed on the HRP. In short, all tasks presented in the Integrated Research Plan (IRP) should address specific risks related to the challenges faced by the astronauts as a result of prolonged exposure to microgravity. All tasks proposed to fill the gaps in knowledge should provide applied, translational data necessary to address the specific risks. Several presentations were made to the SRP during the site visit and the SRP spent sufficient time to address the panel charge, either as a group or in separate sessions. The SRP made a final debriefing to the HRP Program Scientist. Taking the evidence and the risk as givens, the SRP reached the following conclusions: 1) the panel is very supportive of and endorses the present activities of the Sensorimotor Risk; and the panel is likewise supportive of the gaps and associated tasks in the IRP; 2) overall, the tasks addressed the gaps in the IRP; 3) there were some gaps and tasks that merit further enhancement and some new gaps/tasks that the SRP recommends.

Detection methods and data from molecular characterization of genetically modified (GM) events are needed by stakeholders of public risk assessors and regulators. Generally, the molecular characteristics of GM events are incomprehensively revealed by current approaches and biased towards detecting transformation vector derived sequences. GM events are classified based on available knowledge of the sequences of vectors and inserts (insert knowledge). Herein we present three insert knowledge-adapted approaches for characterization GM events (TT51-1 and T1c-19 rice as examples) based on paired-end re-sequencing with the advantages of comprehensiveness, accuracy, and automation. The comprehensive molecular characteristics of two rice events were revealed with additional unintended insertions comparing with the results from PCR and Southern blotting. Comprehensive transgene characterization of TT51-1 and T1c-19 is shown to be independent of a priori knowledge of the insert and vector sequences employing the developed approaches. This provides an opportunity to identify and characterize also unknown GM events. PMID:24088728

Rossmann, C; Brosius, H-B

2013-01-01

Based on theories and empirical results from communication science, the present paper provides an overview of the role of mass media in risk communication. It is guided by the following questions: How do risk issues find their way into the media and how does the media depict them? How do mass-mediated risk messages affect people's perception of risks, knowledge, attitudes, and behavior? What potential does the media have in disseminating health risk information in campaigns? Hence, the present paper aims to provide a basis for the appropriate use of mass media in health risk communication so as to make use of the potential of mass media without neglecting its limits.

2017-04-01

A large-scale cross-sectional study (N = 4002) was set up to determine Flemish secondary school students' willingness to eat genetically modified food (WTE) and to link students' WTE to previously identified key variables from research on the acceptance of genetic modification (GM). These variables include subjective and objective knowledge about genetics and biotechnology, perceived risks and benefits of GM food crops, trust in information from different sources about GM, and food neophobia. Differences between WTE-related variables based on students' grade level, educational track, and gender were analyzed. The students displayed a rather indecisive position toward GM food and scored weakly on a genetics and biotechnology knowledge test. WTE correlated most strongly with perceived benefits and subjective and objective knowledge. The results have clear implications for education, as they reiterate the need to strengthen students' scientific knowledge base and to introduce a GM-related debate at a much earlier stage in their school career.

Abstract Objective To explore what individuals at risk of injury from using paraffin (also known as kerosene) know about paraffin safety, what they do to protect themselves and their families from paraffin-related injury, and how they perceive their risk for such injury. Also, to explore interrelations between these factors and age, sex, education and income. Methods A sample of 238 individuals was randomly recruited from low-income housing districts near Cape Town, South Africa in 2007. Trained research assistants interviewed participants to explore their knowledge about paraffin-related safety and their perceived risk of injury from using paraffin. Researchers inspected participants’ homes to evaluate paraffin safety practices. Descriptive and correlational analyses were conducted. Findings Participants had relatively low levels of knowledge about paraffin-related safety. They had high levels of unsafe practice and their perceived risk of injury was moderate. Knowledge of paraffin safety and safe practices were positively correlated with each other. Greater knowledge showed a negative correlation with the perception of being at risk for injury, but safe practices showed no correlation with perceived risk of injury. Formal education, the number of children in the home and frequency of paraffin use were positively correlated with knowledge but not with safe practices. The only significant correlate to safe practices was greater income, perhaps a reflection of the impact of financial resources on paraffin safety practices. Conclusion To develop successful paraffin safety interventions, it is necessary to understand baseline levels of knowledge, practice and perceived risk of injury among at-risk populations. Our findings could be of value for designing interventions that will increase knowledge, improve safe practices and lead to the accurate perception of the risk of injury from using paraffin.

2018-01-01

This article examined the contribution of indigenous knowledge to disaster risk reduction activities in Zimbabwe. The current discourse underrates the use of indigenous knowledge of communities by practitioners when dealing with disasters’, as the knowledge is often viewed as outdated and primitive. This study, which was conducted in 2016, sought to examine this problem through analysing the potential contribution of indigenous knowledge as a useful disaster risk reduction intervention. Tsholotsho district in Matabeleland, North province of Zimbabwe, which frequently experiences perennial devastating floods, was used as a case study. Interviews and researcher observations were used to gather data from 40 research participants. The findings were that communities understand weather patterns and could predict imminent flooding after studying trees and clouds, and the behaviours of certain animal species. Local communities also use available local resources to put structural measures in place as part of disaster risk reduction interventions. Despite this important potential, the study found that the indigenous knowledge of disaster risk reduction of the communities is often shunned by practitioners. The practitioners claim that indigenous knowledge lacks documentation, it is not found in all generational classes, it is contextualised to particular communities and the knowledge cannot be scientifically validated. The study concluded that both local communities and disaster risk reduction practitioners can benefit from the indigenous knowledge of communities. This research has the potential to benefit communities, policymakers and disaster risk reduction practitioners.

Introduction Human African Trypanosomiasis (HAT) is a vector borne parasitic disease transmitted to humans by infected tse-tse flies cause morbidity including delayed child mental development. Reports of nuisance and bites from tse-tse flies by residents of Kachia grazing led to the study to determine the knowledge, practices and prevalence of HAT among residents of the grazing reserve. Methods We conducted active case search in a cross-sectional study using multi-stage sampling with probability proportionate to size. We administered structured questionnaire on Knowledge, practices relating to HAT prevention and screened for HAT using card agglutination test for Trypanosomiasis (CATT). Knowledge of HAT was scored 0-5 and categorized good (3-5) and poor (0-2) based on score, predisposition to risk of HAT as exposure to ≥two risk factors and, a case of HAT as any respondent that tested positive on CATT. We analysed data using Epi-info and MS-excel. Results Of the 300 respondents, mean age 39(±17years) interviewed, 56.3% were males, 12.0% had good knowledge of HAT and 76.3% were exposed to HAT risk factors. Prevention practices included clearing of overgrown bushes around houses (99%), use of insecticidal treated nets (75.7%) and protective clothing (41.0%). Males {Odds Ratio [OR] 5.0; 95% Confidence Interval (CI) 1.8 - 13.6}, age above 40 years {OR 5.0; 95% CI 1.1 - 24.4} and family history of HAT {OR 8.7; 95% CI 2.4 - 32.1} were significantly associated with HAT knowledge. None tested positive on CATT. Conclusion Despite poor knowledge of HAT, residents practiced HAT preventive measures and zero HAT prevalence was recorded. PMID:27222686

How knowledgeable are men about the medical, environmental and psychological factors that are associated with male infertility? Men, across most demographic groups, have limited knowledge of the various factors that are associated with male infertility. Few surveys have focused on men's knowledge of their own fertility. Studies of both men and women have found that men are comparatively less knowledgeable about issues of fertility and reproductive health. A regionally representative sample of Canadian men completed a web-based survey of male fertility and reproductive health, over a 2-month period in 2015. Men, aged 18-50 years, were recruited for the study. There were 701 male participants, with a mean age of 34.1 years. Each participant was asked to identify factors associated with male infertility; fertility knowledge was assessed through two open-ended questions and a comprehensive list of risk factors and attendant health issues. Men were only able to identify 51% of the risk factors and 45% of the health issues associated with male infertility. Men were most aware of the modifiable risk factors for infertility (e.g. sexually transmitted infections, smoking cigarettes), relative to their knowledge of fixed risk factors (e.g. delayed puberty, size of testicles) and the attendant health issues (e.g. cardiovascular disease, diabetes). The overall level of fertility knowledge did not vary by most demographic characteristics (e.g. age, education, employment, income), though men from ethnic minority groups displayed moderately greater awareness. Additionally, younger men, those with lower incomes and those who had no desire to have future biological children were more likely to identify themselves as unaware of associations with infertility in the open-ended questions. Self-reported knowledge was significantly associated with higher overall knowledge scores. More than half of the sample expressed an interest in obtaining information about male fertility and reproductive health, with the majority of these men indicating that medical professionals and online sources were their preferred methods for receiving information. Participants were self-selected and required to have Internet access in order to participate. This may affect the generalizability of results. Previous studies of fertility knowledge have either omitted men from their samples or when men have been included, they were asked about general fertility or women's fertility. This is the first large-scale survey that focuses solely on men's knowledge of male fertility. Insight into the areas where men's knowledge may be lacking can inform strategies for disseminating fertility-related information and improving men's fertility awareness. Public health initiatives should tailor campaigns to educate men about the lesser known associations with male infertility, particularly those that are most prevalent and preventable through lifestyle modification.

Participation in appropriate exercise can help reduce the risk of falls and falls injury in older people. Delivery of population-level exercise interventions requires an expert workforce with skills in development and delivery of group exercise programs and prescription of individually targeted exercise. This study assessed the current knowledge of university exercise science students (as future exercise professionals) across different levels of study. A structured survey designed to assess knowledge in relation to falls in older people and exercise prescription for falls prevention was administered during second, third and fourth year lectures in seven Australian universities. Students' knowledge was assessed as the percent of correct responses. Overall, 566 students completed the survey and knowledge levels increased significantly with study year. Mean knowledge levels were significantly <70%, indicating limited knowledge. They were lowest for falls risk factor questions and highest for issue/cost related questions in second and third year students. Fourth year students had best knowledge about falls interventions and this was the only group and topic with a mean score >70%. In conclusion, knowledge about falls and exercise prescription for falls prevention in current students does not meet a desired competency level of 70% and is therefore insufficient to ensure an adequately equipped future workforce in this area. There is a clear need for the development and widespread delivery of an evidence-based "exercise for falls prevention" curriculum module for exercise professionals.

Improvements in treatment and earlier diagnosis have both contributed to increased survival for many cancer patients. Unfortunately, many treatments carry a risk of late effects including cardiovascular diseases (CVDs), possibly leading to significant morbidity and mortality. In this paper we describe current knowledge of the cardiotoxicity arising from cancer treatments, outline gaps in knowledge, and indicate directions for future research and guideline development, as discussed during the 2014 Cancer Survivorship Summit organised by the European Organisation for Research and Treatment of Cancer (EORTC). Better knowledge is needed of the late effects of modern systemic treatments and of radiotherapy to critical structures of the heart, including the effect of both radiation dose and volume of the heart exposed. Research elucidating the extent to which treatments interact in causing CVD, and the mechanisms involved, as well as the extent to which treatments may increase CVD indirectly by increasing cardiovascular risk factors is also important. Systematic collection of data relating treatment details to late effects is needed, and great care is needed to obtain valid and generalisable results. Better knowledge of these cardiac effects will contribute to both primary and secondary prevention of late complications where exposure to cardiotoxic treatment is unavoidable. Also surrogate markers would help to identify patients at increased risk of cardiotoxicity. Evidence-based screening guidelines for CVD following cancer are also needed. Finally, risk prediction models should be developed to guide primary treatment choice and appropriate follow up after cancer treatment. PMID:26217163

This study aimed to investigate community pharmacists' knowledge and certainty of adverse effects and contraindications of pharmaceutical products to estimate the risk of error. Factors influencing their knowledge and certainty were also investigated. The knowledge of community pharmacists was assessed in a cross-sectional design using a multiple-choice questions test on the adverse effects and contraindications of active pharmaceutical ingredients and excipients from May 2014 to March 2015. Self-rated certainty scores were also recorded for each question. Knowledge and certainty scores were combined to estimate the risk of error. Out of 315 subjects, 129 community pharmacists (41.0%) completed the 30 multiple-choice questions test on active ingredients and excipients. Knowledge on active ingredients was associated with the year of graduation and obtaining a licence to practice pharmacy. Knowledge on excipients was associated with the degree obtained. There was higher risk of error in items on excipients than those on ingredients (P<0.01). The knowledge of community pharmacists in Palestine was insufficient with high risk of errors. Knowledge of community pharmacists on the safety issues of active ingredients and excipients need to be improved.

Opioid overdose is a public health crisis. This study describes efforts to develop and validate the Brief Opioid Overdose Knowledge (BOOK) questionnaire to assess patient knowledge gaps related to opioid overdose risks. Two samples of illicit opioid users and a third sample of patients receiving an opioid for the treatment of chronic pain (total N = 848) completed self-report items pertaining to opioid overdose risks. A 3-factor scale was established, representing Opioid Knowledge (4 items), Opioid Overdose Knowledge (4 items), and Opioid Overdose Response Knowledge (4 items). The scale had strong internal and face validity. Patients with chronic pain performed worse than illicit drug users in almost all items assessed, highlighting the need to increase knowledge of opioid overdose risk to this population. This study sought to develop a brief, internally valid method for quickly assessing deficits in opioid overdose risk areas within users of illicit and prescribed opioids, to provide an efficient metric for assessing and comparing educational interventions, facilitate conversations between physicians and patients about overdose risks, and help formally identify knowledge deficits in other patient populations.

We sought to quantify the knowledge base among parents and legal guardians presenting to our pediatric emergency department regarding radiation exposure during medical imaging and potential risks to children resulting from ionizing radiation. We sought to examine if a child's previous exposure to medical imaging changed caregiver knowledge base and discern caregivers' preference for future education on this topic. A prospective convenience sample survey was performed of caregivers who presented with their child to our tertiary pediatric emergency department. Parents or legal guardians (18-89 years) who accompanied a child (0-17 years) were eligible for inclusion and approached for enrollment. A structured questionnaire was administered by trained interviewers, and a chart review was conducted to ascertain if their child had a history of previous imaging. Sixty percent of caregivers interviewed (n = 205 of 340) did not associate any long-term negative effects with medical imaging. Among participants who did express a perceived risk from medical imaging radiation exposure, only 50% could indicate a known negative effect from exposure. We found no significant association between a child having had documented imaging studies and awareness of long-term negative effects (P = 0.22). Participants preferred to learn more about this topic from an Internet-based resource (50%), informational pamphlet (38%), or via treating physician (33%). Parents and legal guardians are largely unaware that exposure to radiation during medical imaging carries an inherent risk for their child. Health care providers wishing to educate caregivers should utilize reliable Internet sources, educational pamphlets, and direct communication.

Role of Headmasters, Teachers, and Supervisors in Knowledge Transfer about Occupational Health and Safety to Pupils in Vocational Education

2015-01-01

Background Young people are at an increased risk for illness in working life. The authorities stipulate certain goals for training in occupational health and safety (OHS) in vocational schools. A previous study concluded that pupils in vocational education had limited knowledge in the prevention of health risks at work. The aim of the current study, therefore, was to study how OHS training is organized in school and in workplace-based learning (WPL). Methods The study design featured a qualitative approach, which included interviews with 12 headmasters, 20 teachers, and 20 supervisors at companies in which the pupils had their WPL. The study was conducted at 10 upper secondary schools, located in Central Sweden, that were graduating pupils in four vocational programs. Results The interviews with headmasters, teachers, and supervisors indicate a staggered picture of how pupils are prepared for safe work. The headmasters generally give teachers the responsibility for how goals should be reached. Teaching is very much based on risk factors that are present in the workshops and on teachers' own experiences and knowledge. The teaching during WPL also lacks the systematic training in OHS as well as in the traditional classroom environment. Conclusion Teachers and supervisors did not plan the training in OHS in accordance with the provisions of systematic work environment management. Instead, the teachers based the training on their own experiences. Most of the supervisors did not receive information from the schools as to what should be included when introducing OHS issues in WPL. PMID:26929844

Exposure Knowledge and Risk Perception of RF EMF

The presented study is part of the EU-Project Low EMF Exposure Future Networks (LEXNET), which deals among other things with the issue of whether a reduction of the radiofrequency (RF) electro-magnetic fields (EMF) exposure will result in more acceptance of wireless communication networks in the public sphere. We assume that the effects of any reduction of EMF exposure will depend on the subjective link between exposure perception and risk perception (RP). Therefore we evaluated respondents’ RP of different RF EMF sources and their subjective knowledge about various exposure characteristics with regard to their impact on potential health risks. The results show that participants are more concerned about base stations than about all other RF EMF sources. Concerning the subjective exposure knowledge the results suggest that people have a quite appropriate impact model. The question how RF EMF RP is actually affected by the knowledge about the various exposure characteristics was tested in a linear regression analysis. The regression indicates that these features – except distance – do influence people’s general RF EMF RP. In addition, we analyzed the effect of the quality of exposure knowledge on RF EMF RP of various sources. The results show a tendency that better exposure knowledge leads to higher RP, especially for mobile phones. The study provides empirical support for models of the relationships between exposure perception and RP. It is not the aim to extrapolate these findings to the whole population because the samples are not exactly representative for the general public in the participating countries. PMID:25629026

2015-01-01

Objective Dog-bite injuries pose significant threat to children globally. School-aged children are especially at risk because of their cognitively immature tendency toward low perceived vulnerability to bites, and this risk is elevated further for school-aged children living in rural China due to the large number of stray dogs, all potential rabies carriers, present in their communities. Methods This randomized controlled trial evaluated whether viewing an educational video of testimonials would change safety knowledge, perceived vulnerability, and simulated behaviors with dogs among a sample of 280 third and fourth graders living in rural China. Participants were randomly assigned to view either an educational video of testimonials on dog-bite prevention (treatment) or an educational video of testimonials on drowning prevention (comparison). Safety knowledge, perceived vulnerability to dog bites, and simulated behavior with dogs using a dollhouse model were assessed both before and after exposure to the video of testimonials. Results Children who watched the educational video of testimonials on dog-bite prevention had increased safety knowledge, higher perceived vulnerability, and less risky simulated behaviors with dogs compared to the comparison group. Mediation analysis revealed that the intervention successfully changed children's simulated behaviors with dogs through greater safety knowledge and increased perceived vulnerability. Conclusions Results suggest the incorporation of testimonials into injury prevention programs has potential for broad global dissemination. The fact that both increased knowledge and heightened perceived vulnerability mediated changes in simulated behavior suggests the dual roles of knowledge and appraisal on children's injury-risk behavior.

The controversy over the world's first genetically modified (GM) wheat, Roundup Ready wheat (RRW), challenged the efficacy of 'science-based' risk assessment, largely because it excluded the public, particularly farmers, from meaningful input. Risk analysis, in contrast, is broader in orientation as it incorporates scientific data as well as socioeconomic, ethical, and legal concerns, and considers expert and lay input in decision-making. Local knowledge (LK) of farmers is experience-based and represents a rich and reliable source of information regarding the impacts associated with agricultural technology, thereby complementing the scientific data normally used in risk assessment. The overall goal of this study was to explore the role of farmer LK in the a priori risk analysis of RRW. In 2004, data were collected from farmers using mail surveys sent across the three prairie provinces (i.e., Manitoba, Saskatchewan, and Alberta) in western Canada. A stratified random sampling approach was used whereby four separate sampling districts were identified in regions where wheat was grown for each province. Rural post offices were randomly selected in each sampling district using Canada Post databases such that no one post office exceeded 80 farms and that each sampling district comprised 225-235 test farms (n = 11,040). In total, 1,814 people responded, representing an adjusted response rate for farmers of 33%. A subsequent telephone survey showed there was no non-response bias. The primary benefits associated with RRW were associated with weed control, whereas risks emphasized the importance of market harm, corporate control, agronomic problems, and the likelihood of contamination. Overall, risks were ranked much higher than benefits, and the great majority of farmers were highly critical of RRW commercialization. In total, 83.2% of respondents disagreed that RRW should have unconfined release into the environment. Risk was associated with distrust in government and corporations, previous experience with GM canola, and a strong belief in the importance of community and environment. Farmers were critical of expert-based risk assessment, particularly RRW field trials, and believed that their LK was valuable for assessing agbiotechnology as a whole. Over 90% of canola production across the Canadian prairies makes use of herbicide-tolerant (HT) varieties. Yet, respondents were generally uniform in their criticism of RRW, regardless whether they were HT users, non-HT-users, conservation tillage or organic in approach. They had a sophisticated understanding of how GM trait confinement was intrinsically tied to grain system segregation and, ultimately, market accessibility, and were concerned that gene flow in RRW would not be contained. Organic farmers were particularly critical of RRW, in large part because certification standards prohibit the presence of GM traits. Farmers practicing conservation tillage were also at relatively great risk, in part because their dependence on glyphosate to control weeds increases the likelihood that RRW volunteer would become more difficult and costly to control. This research is the first of its kind to include farmer knowledge in the a priori risk analysis of GM crops and, arguably, given its prairie-wide scope, is the largest scale, independent-farmer-focused study on GM crops ever conducted. The surprising uniformity in attitudes between users and non-users of GM technology and among organic, conventional, conservation tillage and GM using farmers speaks to the ability of farmers to discriminate among HT varieties. Our results clearly show that prairie farmers recognize that the risks associated with RRW commercialization outweigh any benefits. Farmer knowledge systems are holistic in nature, incorporating socioeconomic, cultural, political, and agroecological factors that all can contribute meaningfully to the pre-release evaluation of GM crops. The inclusion of farmers and other stakeholders in risk assessment will also help enhance and even restore public confidence in science-focused approaches to risk assessment. Although farmers are highly knowledgeable regarding RRW and arguably any agricultural technology, their expertise continues to be overlooked by decision-makers and regulators across North America.

Sustainable development and next generation's health: a long-term perspective about the consequences of today's activities for food safety.

Development is defined sustainable when it meets the needs of the present without compromising the ability of future generations to meet their own needs. Pivoting on social, environmental and economic aspects of food chain sustainability, this paper presents the concept of sustainable food safety based on the prevention of risks and burden of poor health for generations to come. Under this respect, the assessment of long-term, transgenerational risks is still hampered by serious scientific uncertainties. Critical issues to the development of a sustainable food safety framework may include: endocrine disrupters as emerging contaminants that specifically target developing organisms; toxicological risks assessment in Countries at the turning point of development; translating knowledge into toxicity indexes to support risk management approaches, such as hazard analysis and critical control points (HACCP); the interplay between chemical hazards and social determinants. Efforts towards the comprehensive knowledge and management of key factors of sustainable food safety appear critical to the effectiveness of the overall sustainability policies.

Seismic hazard assessment based on the Unified Scaling Law for Earthquakes: the Greater Caucasus

Losses from natural disasters continue to increase mainly due to poor understanding by majority of scientific community, decision makers and public, the three components of Risk, i.e., Hazard, Exposure, and Vulnerability. Contemporary Science is responsible for not coping with challenging changes of Exposures and their Vulnerability inflicted by growing population, its concentration, etc., which result in a steady increase of Losses from Natural Hazards. Scientists owe to Society for lack of knowledge, education, and communication. In fact, Contemporary Science can do a better job in disclosing Natural Hazards, assessing Risks, and delivering such knowledge in advance catastrophic events. We continue applying the general concept of seismic risk analysis in a number of seismic regions worldwide by constructing regional seismic hazard maps based on the Unified Scaling Law for Earthquakes (USLE), i.e. log N(M,L) = A - B•(M-6) + C•log L, where N(M,L) is the expected annual number of earthquakes of a certain magnitude M within an seismically prone area of linear dimension L. The parameters A, B, and C of USLE are used to estimate, first, the expected maximum magnitude in a time interval at a seismically prone cell of a uniform grid that cover the region of interest, and then the corresponding expected ground shaking parameters including macro-seismic intensity. After a rigorous testing against the available seismic evidences in the past (e.g., the historically reported macro-seismic intensity), such a seismic hazard map is used to generate maps of specific earthquake risks (e.g., those based on the density of exposed population). The methodology of seismic hazard and risks assessment based on USLE is illustrated by application to the seismic region of Greater Caucasus.

Abstract Objective To determine physicians’ level of awareness and knowledge of Lyme disease (LD) in a low-prevalence area and whether physicians’ practices align with current guidelines for treatment of LD. Design A 23-item questionnaire assessing demographic characteristics, general knowledge about LD, laboratory testing for LD, and responses to 3 clinical scenarios. Setting British Columbia (BC). Participants Pediatricians, FPs, and internal medicine specialists who were licensed to practise in BC. Main outcome measures Knowledge of signs and symptoms of LD, beliefs about risk of LD, attitudes toward LD in patients in their practices, and application of accepted practice guidelines for the treatment of LD in clinical scenarios. Results Overall, 80.6% of respondents were FPs. Average knowledge score was 72.5% for FPs and 75.0% for other specialists. Most respondents (75.6% of FPs and 71.8% of other specialists) underestimated the occurrence of erythema migrans (EM), and only 26.1% and 28.3%, respectively, knew that EM alone was diagnostic for LD. A total of 30.5% of FPs and 12.1% of other specialists reported having treated a patient for the disease despite not believing that the patient had LD. Of all the respondents, 62.1% knew that LD was a reportable disease in BC. Respondents’ reports of risk of LD in their areas were appropriately associated with actual risk based on ecological niche. Conclusion Physicians are knowledgeable about the clinical signs and symptoms of LD and aware of the risk of the disease despite being in a low-endemic area. Physicians in BC are comfortable with treating patients empirically for LD. Education is needed to inform physicians that EM is diagnostic and no laboratory testing is indicated before treatment. Raising awareness among physicians that LD is reportable might improve reporting of future cases. PMID:22734172

The aim of the study was to compare knowledge and awareness of heart attacks/heart disease and perceived risk for future heart attack in Asian/Pacific Islander women, compared to other racial and ethnic groups. In this cross-sectional study, 318 women enrolled in a mobile phone-based physical activity education trial were analyzed. Heart attack knowledge, self-efficacy for recognizing and responding to heart attack symptoms, and perceived risk for a future heart attack were measured. Analyses were conducted using logistic, proportional odds, and linear regression models, depending on the outcome and adjusting for age. Pairwise differences between Asian/Pacific Islanders and the other four groups were assessed using a Bonferroni correction (p < 0.0125). Asian/Pacific Islander women had significantly lower total scores for knowledge of heart attack and self-efficacy for heart attack recognition and care seeking behavior compared to the Caucasian women (p = 0.001 and p = 0.002, respectively). However, perceived risk did not differ among the groups. Forty-six percent of the Asian American women, compared to 25% of Caucasian women, falsely believed "breast cancer is the number one cause of death for women (p = 0.002)." In addition, Asian/Pacific Islander women were less likely to report "arm pain, numbness, tingling, or radiating" as one of the heart attack symptoms compared to the Caucasian and the multiracial group (34%, 63% [p < 0.001], and 66% [p = 0.004], respectively). These findings highlight the urgent need to develop effective, tailored campaigns to close the knowledge gap between Asian/Pacific Islander women and Caucasian women.

Understanding community pharmacist perceptions and knowledge about HIV preexposure prophylaxis (PrEP) therapy in a Mountain West state.

Preexposure prophylaxis (PrEP) therapy is prescribed to HIV-negative individuals who are at high risk of contracting the virus to reduce the risk of transmission. Adherence to therapy is essential for optimal treatment outcome, and community pharmacists have an important role in achieving this through patient counseling. The objectives of this study were to measure pharmacists' actual knowledge about HIV PrEP therapy, perceptions about their HIV PrEP therapy knowledge, and intention to counsel patients about PrEP therapy. A cross-sectional survey was conducted among community pharmacists in Utah to measure their actual knowledge and perceptions of knowledge about PrEP therapy based on the basic information from the Centers for Disease Control website. In addition, the pharmacist's intention to counsel patients on PrEP therapy was measured with the use of the validated Godin 12-item tool. Descriptive analyses and t tests identified characteristics based on gender, degree earned, and years of practice in pharmacy. Regression analysis determined significant predictors of the intention to counsel. There were 251 responses (75% PharmD, 61% male, 42% >10 years' experience as a pharmacist). An exploratory factor analysis of the Godin 12-item tool demonstrated 4 domains: beliefs about capabilities, social influence, moral norms, and intention to counsel patients. There was no difference in the intention to counsel based on gender. Pharmacists with a PharmD and less than 10 years of experience had significantly higher knowledge and intention to counsel. The actual knowledge score of the respondents was significantly higher than their perceptions of their knowledge. Multiple regression results showed that the beliefs about capabilities and social influence were significant predictors of intention to counsel. Educating community pharmacists on PrEP therapy using pharmacists who are considered to be opinion leaders in the pharmacy profession can affect the social influence and beliefs about capabilities domains, which in turn can increase counseling on PrEP therapy.

The knowledge base surrounding how to most effectively prepare and sustain practitioner knowledge and skills for suicide risk assessment and management is limited. This study examined the impact of a 6-hr continuing education training, and the effect of a posttraining reminder system, on mental health practitioners' knowledge, attitudes, and behavior surrounding suicide assessment and intervention. Data were obtained prior to the training, immediately after the training, and at the 3-month follow-up. Medical record data were abstracted for a subsample of practitioners. Participants were randomly assigned to an e-mail reminder condition or no reminder condition that provided information related to the training. All practitioners demonstrated increase s in suicide assessment knowledge and attitudes for engaging in suicide risk assessments from pre- to posttest, and gains were maintained at the 3-month follow-up. There was no effect of the e-mail reminder on practitioner knowledge, attitudes, or behaviors compared with the condition without the e-mail reminder. The use of e-mail reminders was not associated with any additional changes. Limitations include predominantly self-report and small sample. Strategies to effectively change practitioner knowledge, attitudes, and behaviors toward suicidal clients may include continuing education. Efficient and effective designs of reminder systems for augmenting and supporting suicide assessment management training are needed.

We determined knowledge of the health benefits of consuming beans, and assessed if awareness varied by acculturation status among Hispanic and non-Hispanic low-income women. We used a self-administered survey with Iowa women aged 18-65 years who were eligible to receive income-based services through 2 healthcare clinics, a WIC clinic, and Extension Outreach. Chi-square and ANOVA were used to compare bean health benefit knowledge, demographics, health-risk factors, nutrition information seeking, and self-efficacy by acculturation categories. Of the 158 women who completed the survey, 58% were Hispanic, with a mean age of 36 years. In terms of acculturation, 24% were Hispanic-dominant, 30% bicultural, and 46% English dominant. Over 50% of all respondents did not know bean consumption lowered cholesterol, aided blood glucose control, or reduced some cancer risks. Responses for 5 of 7 knowledge statements differed significantly by acculturation. Hispanic-dominant and bicultural women reported significantly better health, higher bean consumption, and less cigarette smoking than English-dominant women. Bicultural and English-dominant women were more likely to use the Internet for nutrition information. There are knowledge gaps about the health benefits of bean consumption among low-income women. Nutrition education to improve their knowledge may lead to increased bean consumption, reducing health disparities and improving nutrition.

Heat waves threaten human health given the fast changing climatic scenarios in the recent past. Adaptation to heat waves would take place when people perceive their impacts based on their knowledge. The present study examines perception level and its determinants resulting in adaptation to heat waves in Pakistan. The study used cross-sectional data from urban and peri-urban respondents of Faisalabad District. The study employs a health belief model to assess risk perception among the respondents. Logistic model is used to determine factors affecting level of knowledge, perception and adaptation to heat waves. Around 30% of peri-urban respondents have a low level of knowledge about the fatal impacts of heat waves. Risk perception of heat waves is very low among urban (57%) and peri-urban (66%) respondents. Households' knowledge on heat waves is significantly related to age, gender, education, wealth and access to health services. Determinants of perception include knowledge of heat waves, age and joint effect of marital status and knowledge while income level, family size, urban/peri-urban background, perceived barriers, perceived benefits and cues to action significantly affect adaptation to heat waves. To reduce deadly health impacts, mass awareness campaigns are needed to build perception and improve adaptation to heat waves.

Outcome-expectation beliefs and knowledge may ultimately influence behavior for cancer prevention. The aims of this study were to measure changes in knowledge and beliefs about cancer prevention before and after viewing a television advertisement and identify the factors affecting receptivity to its messages. A one-group pretest-posttest design was used in this study of 1,000 individuals aged 20 to 65 years who were recruited online in November 2014. The outcome variables included cancer prevention beliefs based on the Health Belief Model (five items) and knowledge about risk factors for cancer (seven items). Perceived susceptibility, perceived benefits, and self-efficacy increased significantly and their perceived severity and perceived barriers decreased significantly, after participants viewed the television advertisement. Correct responses to questions about risk factors also increased significantly, except for smoking. The main factors affecting changes in the outcome variables were age, interest in cancer prevention, social network, satisfaction with the ad, and pretest scores. Television advertisements with positive frameworks can be an efficient channel of improving beliefs and knowledge about cancer prevention in a short period. The continuous development of intervention materials that consider the demographics, needs, and satisfaction of the target group will be necessary for future studies.

Aflatoxin control--how a regulatory agency managed risk from an unavoidable natural toxicant in food and feed.

The control by the Food and Drug Administration (FDA) of aflatoxin, a relatively recently discovered, unavoidable natural contaminant produced by specific molds that invade a number of basic food and feedstuffs, provides an example of the varying forces that affect risk assessment and management by a regulatory Agency. This is the story of how the FDA responded to the initial discovery of a potential carcinogenic hazard to humans in a domestic commodity, to the developing information concerning the nature of the hazard, to the economic and political pressures that are created by the impact of natural forces on regulatory controls, and to the restraints of laws within which the Agency must work. This story covers four periods: the years of discovery and action decisions on the basis of meager knowledge and the fear of cancer; the years of tinkering on paper with the regulatory process, the years of digestion of the accumulating knowledge, and the application of that knowledge to actions forced by natural events; and an audit of the current status of knowledge about the hazard from aflatoxin, and proposals for regulatory control based on that knowledge.

Objective We aimed to measure cancer knowledge and feasibility of a screening colonoscopy among a cohort of individuals at higher risk of colon cancer. Methods This study was conducted as part of an ongoing screening cohort, in which first degree relatives (FDRs) of patients with colon cancer are invited to participate in a free of charge screening colonoscopy. We enrolled 1017 FDRs in the study between 2013 and 2014 measuring their data on demographics, cancer knowledge and colonoscopy uptake. A p value of <0.05 was considered statistically significant. Results The relative's mean age was 48.7 years. Only about 28% of FDRs were aware of their increased risk for cancer, near 35.0% had ever heard about colonoscopy with 22% aware of the correct age to start screening. Comparing cancer knowledge of FDRs at high risk versus those at moderate risk, we recorded non-significant differences (p>0.05). Almost two-thirds of FDRs expressed willingness to undergo a colonoscopy and 49.2% completed the procedure, of which 12.8% had advanced neoplasm. Conclusions Our data indicated that remarkable numbers of FDRs were not still informed of their cancer risk or never received a physician recommendation for screening. The desirable uptake at first invitation, which would be higher over successive invitations, supports the feasibility of a family-based recruitment approach for early screening. This has promising implications to introduce targeted screening colonoscopy into the healthcare system in Iran and other developing nations. PMID:27998901

To understand the knowledge and perceptions of type 2 diabetes and to explore preferable educational strategies in the non-diabetic offspring of patients with the disease. Type 2 diabetes is an increasingly prevalent disease with significant long-term consequences. Offspring of patients with type 2 diabetes have an increased risk of developing the disease compared with the general population. Previous studies have shown that offspring have a poor perception of their own risk. A qualitative study was carried out using semi-structured one-to-one interviews. Analysis was completed using a structured framework approach. Research was carried out during January-March 2011 in the north east of UK. Six offspring of patients diagnosed with the disease were interviewed. Participants balanced positive and negative aspects of their lifestyle behaviours to estimate their own risk. They had adequate knowledge of healthy lifestyle behaviours, but were uncertain about the long-term effects and seriousness of the disease and the role of inheritance. Behavioural changes at an individual level would only be motivated by an event, which would impact on their own health. Participants believed that 'fear'-based strategies to health promotion would be most effective to encourage behaviour change. Knowledge of individual risk and why diabetes was serious was limited and variable. The health behaviours of this at-risk group were complex. Nurses engaged in the care of at-risk individuals must take this complexity into account when developing and implementing multi-faceted strategies to improve awareness. © 2013 John Wiley & Sons Ltd.

The disproportionately large number of traffic accidents of young novice drivers highlights the need for an effective driver education program. The Goals for Driving Education (GDE) matrix shows that driver education must target both lower and higher levels of driver competences. Research has indicated that current education programs do not emphasize enough the higher levels, for example awareness and insight. This has raised the importance of insight programs. On the Road (OtR), a Flemish post-license driver education program, is such an insight program that aims to target these higher levels. The program focus is on risky driving behavior like speeding and drink driving. In addition, the program addresses risk detection and risk-related knowledge. The goal of the study was to do an effect evaluation of this insight program at immediate post-test and 2 months follow-up. In addition, the study aimed to generalize the results of this program to comparable programs in order to make usable policy recommendations. A questionnaire based on the Theory of Planned Behavior (TPB) was used in order to measure participants' safety consciousness of speeding and drink driving. Moreover, we focused on risk detection and risk-related knowledge. Participants (N=366) were randomly assigned to a baseline-follow-up group or a post-test-follow-up group. Regarding speeding and driving, we found OtR to have little effect on the TPB variables. Regarding risk detection, we found no significant effect, even though participants clearly needed substantial improvement when stepping into the program. Regarding risk-related knowledge, the program did result in a significant improvement at post-test and follow-up. It is concluded that the current program format is a good starting point, but that it requires further attention to enhance high level driving skills. Program developers are encouraged to work in a more evidence-based manner when they select target variables and methods to influence these variables. Copyright © 2014 Elsevier Ltd.

Edwards, Quannetta T; Seibert, Diane

2010-07-01

Numerous studies have shown that healthcare providers, including nurse practitioners (NPs) fail to provide breast cancer risk assessment (BrCRA) in primary care settings. A potential barrier to the use of BrCRA is insufficient knowledge or training of risk assessment. The purpose of this study was to analyze the outcome of a BrCRA program developed to enhance NPs' knowledge of risk assessment and use of empiric risk assessment models. Thirty-five NPs participated in a before-after (pretest-posttest design) study evaluating the effectiveness of a BrCRA education program conducted at a national NP conference. Demographics, pre/post knowledge, and course satisfaction measures were all examined as a part of this pilot study. Continuing education through the implementation of a BrCRA program significantly increased NPs knowledge in assessing breast cancer risk and the use of empiric risk assessment models. Many healthcare providers, including NPs, are inadequately prepared to assess a woman's risk for breast cancer. Understanding breast cancer risk assessment is essential if NPs are to provide appropriate counseling, management, and referral strategies needed to reduce a woman's risk for developing the disease. Continuing education provides one means to enhance NP's knowledge of BrCRA.

Software for Probabilistic Risk Reduction

2004-01-01

A computer program implements a methodology, denoted probabilistic risk reduction, that is intended to aid in planning the development of complex software and/or hardware systems. This methodology integrates two complementary prior methodologies: (1) that of probabilistic risk assessment and (2) a risk-based planning methodology, implemented in a prior computer program known as Defect Detection and Prevention (DDP), in which multiple requirements and the beneficial effects of risk-mitigation actions are taken into account. The present methodology and the software are able to accommodate both process knowledge (notably of the efficacy of development practices) and product knowledge (notably of the logical structure of a system, the development of which one seeks to plan). Estimates of the costs and benefits of a planned development can be derived. Functional and non-functional aspects of software can be taken into account, and trades made among them. It becomes possible to optimize the planning process in the sense that it becomes possible to select the best suite of process steps and design choices to maximize the expectation of success while remaining within budget.

The premise of this comment perpetuates an unfortunate trend among some radiation researchers to minimize potential risks to human tissue from low-radiation sources. In fact, this discussion on the risk uncertainties of low-dose radiation further illustrates the need for more measurements and a program of active monitoring, especially when solar eruptive events can substantially elevate the radiation environment. This debate also highlights the context of a bigger problem; i.e., how do we as professionals act with due diligence to take the immense body of knowledge of space weather radiation effects on human tissue and distil it into ideas that regulatory agencies can use to maximize the safety of a population at risk. The focus of our article on radiation risks due to solar energetic particle events starts with our best assessment of risks and is based on the body of scientific knowledge while, at the same time, erring on the side of public safety. The uncertainty inherent in our assessment is accepted and described with this same philosophy in mind.

Notwithstanding the efforts of health educators and other health professionals regarding tobacco and smoking cessation, research indicates that hookah smoking among college students remains a health concern. Research shows an upward trend in college students' hookah use. The purpose of this study was to identify and describe potential patterns/differences in college students' hookah use, and the relations among attitudes toward and knowledge about hookah use and use of this drug. A four-page, 20-item survey was used to collect data from participants (N = 403) and to measure participants 'recent use, knowledge of health risks, attitudes and reasons for hookah use among college students. Results indicated increased prevalence rates (53.8%) among participants of this study. Participants' recent hookah use was consistent with that of current research. Study findings supports current research, which found that college students have low negative perceptions of the health risks (addictive and detrimental properties) of hookah use. Analyses also determined that college students' attitudes toward hookah was associated with use of this drug. Regarding reasons why students may use hookah, data analysis indicated statistical significance in lifetime hookah use based on reasons for use. Study provide information for health educators creating hookah risk awareness educational programs aimed at reducing rates of hookah smoking among college students.

In 2008, the Australian Government launched a mass-media campaign 'Measure-Up' to reduce lifestyle-related chronic disease risk. Innovative campaign messages linked waist circumference and chronic disease risk. Communication channels for the campaign included television, press, radio and outdoor advertising and local community activities. This analysis examines the impact of the campaign in the state of New South Wales, Australia. Cross-sectional telephone surveys (n = 1006 adults pre- and post-campaign) covered self-reported diet and physical activity, campaign awareness, knowledge about waist circumference, personal relevance of the message, perceived confidence to make lifestyle changes and waist-measuring behaviours. The campaign achieved high unprompted (38%) and prompted (89%) awareness. From pre- to post-campaign, knowledge and personal relevance of the link between waist circumference and chronic disease and waist measuring behaviour increased, although there were no significant changes in reported fruit and vegetable intake nor in physical activity. Knowledge of the correct waist measurement threshold for chronic disease risk increased over 5-fold, adjusted for demographic characteristics. 'Measure-Up' was successful at communicating the new campaign messages. Continued long-term investment in campaigns such as 'Measure-Up', supplemented with community-based health promotion, may contribute to population risk factor understanding and behaviour change to reduce chronic disease.

To assess any improvements in knowledge of asthma patients after a tailored education program delivered by pharmacists and measure the sustainability of any improvements. To ascertain patients' perceptions about any changes in their knowledge. Ninety-six specially trained pharmacists recruited patients based on their risk of poor asthma control. A tailored intervention was delivered to patients based on individual needs and goals, and was conducted at three or four time points over six months. Asthma knowledge was assessed at the beginning and end of the service, and six and 12 months after it had ended. Patients' perceptions of the impact of the service on their knowledge were explored qualitatively in interviews. The 96 pharmacists recruited 570 patients, 398 (70%) finished. Asthma knowledge significantly improved as a result of the service (7.65 ± 2.36, n=561, to 8.78 ± 2.14, n=393). This improvement was retained for at least 12 months after the service. Patients reported how the knowledge and skills gained had led to a change in the way they managed their asthma. Improvements in knowledge are achievable and sustainable if pharmacists used targeted educational interventions. Pharmacist educational interventions are an efficient way to improve asthma knowledge in the community. Crown Copyright © 2011. Published by Elsevier Ireland Ltd. All rights reserved.

Background There is a high incidence of adverse effects from non-steroidal antiinflammatory drugs (NSAIDs) in Thailand, but patients' perceptions and knowledge of NSAID risks is unknown. Objective This study aims to assess patients' perceptions and knowledge of NSAID risks and factors affecting them. Setting University hospital in North-East of Thailand. Method A Cross-sectional study conducted over 4 months, using a self-administered questionnaire. Patients prescribed NSAIDs for at least one month duration from orthopaedic clinic were recruited using systematic random sampling. Main outcome measure Patients' perceptions on NSAID risks, knowledge on risk factors, and their associated factors. Results A total of 474 questionnaires were assessed. Overall perceptions of risks was low (scoring below five on a 0-10 visual analogue scale), with risks associated with the renal system scoring highest. Perceived risk of gastrointestinal problems differed between patients using non-selective and selective NSAIDs (3.47 ± 2.75 vs 2.06 ± 2.98; P < 0.001). Receiving side effect information from a health professional was associated with higher risk perception. Most patients (80 %) identified high doses, renal disease and gastrointestinal ulcer increased risks of NSAIDs, but fewer than half recognized that use in the elderly, multiple NSAID use, drinking, hypertension and cardiovascular disease also increased risk of adverse events. Having underlying diseases and receiving side effect information were associated with 1.6-2.0 fold increased knowledge of NSAID risks. Conclusion Perceptions and knowledge concerning NSAID risks was generally low in Thai patients, but higher in those who had received side effect information. Risk-related information should be widely provided, especially in high-risk patients.

To explore the level of Listeria awareness among pregnant women attending antenatal services and to gain a better understanding of women's knowledge of Listeria risk and factors that affect their practice in this regard. This was a cross-sectional study carried out from April to November 2006 using a convenience sample of pregnant women attending antenatal clinics/classes in one private and two major public hospitals in South Eastern Sydney and Illawarra Area Health Services, New South Wales. Women were asked to participate by completing a self-administered questionnaire based on the standard food safety recommendations for pregnant women to avoid Listeria infection. The association between different socio-demographic variables and Listeria knowledge, and related food practices, were investigated using bivariate and multivariate analysis. Nearly half of the 586 respondents had received some kind of information on Listeria prevention. The main channel for obtaining information was social environment. More than 57% had an incomplete knowledge of foods with high Listeria risk, and approximately 25% continued the consumption of these foods with a relatively high frequency. A strong association was found between women's knowledge and their practice. Lower education and household income, unplanned pregnancy and non-English-speaking background were associated with incomplete knowledge and more frequent consumption of at-risk foods. The provision of advice on Listeria prevention appears to be insufficient during prenatal consultations early in pregnancy and needs to be improved as an essential component of these services.

Context: Hypertension in youth is increasing, but there is a dearth of data about the knowledge of risk factors in this age group. Aims: To assess the knowledge of risk factors of hypertension among university students and associate it with the blood pressure, physical activity, family history of cardiovascular disease (CVD), and sociodemographic variables. Materials and Methods: A cross-sectional survey among students enrolled in the first year, in the four academic programs, with the use of a validated, self-administered questionnaire on physical activity in the past 30 days and knowledge of risk factors of hypertension. A score of 6 on 11 was considered as good knowledge for modifiable risk factors. Blood pressure was also measured. The data was analyzed using PASW-17, Chi square test, and binary logistic regression analysis was done. Results: Of the 110 participants, 69.2% were < 20 years of age, 76.4% were females, and 40% were Arabs. Stress, high cholesterol, obesity, and smoking were identified as risk factors by 75.5, 73.6, 77.6, and 71.8%, respectively; 69.1% considered high salt intake and 62.7% considered high calorie diet as risk factors. Energy drink was considered as a risk factor by 64.5%, coffee consumption 35.5%, physical inactivity 47%, and oral contraceptives 13.6%. Half the group did not consider a family history of CVD as a risk factor, 60% did not consider older age as a risk factor, and 88% did not think male gender was a risk factor. Knowledge of modifiable risk factors was better than that of non-modifiable risk factors. Although nationality, course of study, raised blood pressure, and history of diabetes showed significant association with good knowledge, their net effect was not significant by the Adjusted Odd's Ratio. Conclusions: The study identified some gaps in knowledge regarding both modifiable and non-modifiable risk factors of hypertension among students. A larger study would enable health promotion activities tailored to the needs of this age group. PMID:22175039

ᅟ: The increase in cardiovascular disease (CVD) risk in rheumatoid arthritis (RA) is well known; however, appropriate management of this elevated risk in rheumatology clinics is less clear. By critically reviewing literature published within the past 5 years, we aim to clarify current knowledge and gaps regarding CVD risk management in RA. We examine recent guidelines, recommendations, and evidence and discuss three approaches: (1) RA-specific management including treat-to-target and medication management, (2) assessment of comprehensive individual risk, and (3) targeting traditional CVD risk factors (hypertension, smoking, hyperlipidemia, diabetes, obesity, and physical inactivity) at a population level. Considering that 75% of US RA visits occur in specialty clinics, further research is needed regarding evidence-based strategies to manage and reduce CVD risk in RA. This review highlights clinical updates including US cardiology and international professional society guidelines, successful evidence-based population approaches from primary care, and novel opportunities in rheumatology care to reduce CVD risk in RA.

Suicide is strongly associated with mental disorders, particularly with depression. There is insufficient knowledge to what extent sociodemographic and behavioral characteristics contribute to suicide risk. A population-based cohort study on three independent cross-sectional MONICA/KORA Augsburg surveys with 12,888 subjects (6456 men, 6432 women) was followed up on average for 12.0 years. Information on sociodemographic characteristics, chronic disease conditions, smoking habits, alcohol consumption, depressive symptoms, personality type, and other psychodiagnostic parameters was assessed by standardized interviews. Cox proportional hazards regression analyses were used to compute hazard ratios (HRs) as estimates of relative risks for suicide mortality. Additionally, population-attributable risks were calculated. Within the follow-up period, a total of 1449 persons had died, 38 of them by suicide. Although several variables were associated with increased risk in the basic analyses, only obesity (HR=2.73), smoking (HR=2.23), and living alone (HR=2.19) remained significantly associated with suicide additionally to male sex (HR=3.57) and depressed mood (HR=2.01) in a multivariate analysis. The generalization of our findings to countries with different social, economic or cultural conditions may be questioned. Our findings extend the knowledge about sociodemographic and behavioral risk factors for suicide in the general population: Suicide prevention measures should not consider only subjects with mental disorders but also address other adverse conditions. © 2013 Published by Elsevier B.V.

The aim of the research was to gain increased knowledge regarding the sexual risk behaviour of school-going young people in South Africa after two decades of HIV-education in schools, to contribute to the development of improved HIV prevention strategies. In collaboration with the Department of Education, a sample of 5305 learners (between 10 and 18 years in Grades 5-12) from high-risk communities were identified. They completed a survey that assessed self-reported sexual risk behaviour and variables that potentially underlie sexual risk, such as attitudes towards preventive behaviour, perceived social norms and self-efficacy (based on the theory of planned behaviour [TPB]) and social factors like caregiver relationships and gender norms (based on the social ecological theory). Lifetime sex was reported by 49.4% of boys and 30.5% of girls in Grades 8-12, while 56% of the sexually active young people reported consistent condom use. Accurate knowledge about HIV transmission was low (37.8%). Regression analysis showed that risk behaviour was more prominent among older male youths, who perceived social norms as encouraging sexual activity, who use alcohol excessively, and who have negative attitudes towards abstinence. Perceived traditional community gender norms and negative relationships with caregivers were also associated with sexual risk behaviour. This research showed that the TPB can be used in planning HIV prevention interventions for young people. It also revealed that HIV-prevention strategies should focus beyond educating the individual, to address community factors such as improving caregiver relationships, the culture of substance abuse, peer group norms and inequality in community gender norms. These community processes influence young people's behaviour and need to be addressed to allow the youth to make healthy behavioural choices.

The paper presents a project aiming to develop a knowledge-based system for documentation and analysis of defects of cultural heritage objects and monuments. The MONDIS information system concentrates knowledge on damage of immovable structures due to various causes, and preventive/remedial actions performed to protect/repair them, where possible. The currently built system is to provide for understanding of causal relationships between a defect, materials, external load, and environment of built object. Foundation for the knowledge-based system will be the systemized and formalized knowledge on defects and their mitigation acquired in the process of analysis of a representative set of cases documented in the past. On the basis of design comparability, used technologies, materials and the nature of the external forces and surroundings, the developed software system has the capacity to indicate the most likely risks of new defect occurrence or the extension of the existing ones. The system will also allow for a comparison of the actual failure with similar cases documented and will propose a suitable technical intervention plan. The system will provide conservationists, administrators and owners of historical objects with a toolkit for defect documentation for their objects. Also, advanced artificial intelligence methods will offer accumulated knowledge to users and will also enable them to get oriented in relevant techniques of preventive interventions and reconstructions based on similarity with their case.

Despite demonstrated efficacy, acceptance of selective estrogen receptor modulators (SERMs), such as tamoxifen, for breast cancer risk reduction remains low. Delivering SERMs via local transdermal therapy (LTT) could significantly reduce systemic effects and therefore may increase acceptance. We aim to assess women's knowledge of breast cancer prevention medications and views on LTT of SERMs. Focus groups were conducted with healthy women identified through the comprehensive breast center of a large urban cancer institution. Group discussions covered risk perceptions, knowledge of and concerns about risk reducing medications. Participants reported their perceived risk for breast cancer (average, below/above average), preference for SERMs in a pill or gel form, risk factors, and prior physician recommendations regarding risk-reducing medicines. Participants' breast cancer risk was estimated using tools based on the Gail Model. Trained personnel examined all qualitative results systematically; risk perceptions and preferred method of medication delivery were tallied quantitatively. Four focus groups (N = 32) were conducted. Most participants had at least a college degree (78.2 %) and were of European (50 %) or African ancestry (31 %). The majority (72 %) were at elevated risk for breast cancer; approximately half of these women perceived themselves to be at elevated risk. Few participants had prior knowledge of preventive medications. The women noted a number of concerns about LTT, including dosage, impact on day-to-day life, and side effects; nonetheless, over 90 % of the women stated they would prefer LTT to a pill. Awareness of preventive medications was low even in a highly educated sample of high-risk women. If given a choice in the route of administration, most women preferred a gel to a pill, anticipating fewer side effects. Future work should focus on demonstrating equivalent efficacy and reduced toxicity of topical over oral medications and on raising awareness of chemopreventive options for breast cancer.

Although considerable evidence has demonstrated that physical activity is associated with breast cancer prevention, few studies have assessed the level of awareness of this association. Awareness is a key first step to successful of behavior change. Increasing awareness may contribute to promote physical activity and prevent breast cancer at the population level. The present study examined the prevalence and correlates of awareness about the role of physical activity in breast cancer prevention among Japanese women. 1,000 Japanese women aged 20-69 years (mean age: 44.3 ± 13.4 years) who responded to an internet-based cross-sectional survey. Awareness of the role of physical activity in breast cancer prevention, knowledge of breast cancer (symptom, risk factor, screening), exposure to information about physical activity and cancer, a self-reported physical activity, and sociodemographic variables (age, marital status, having a child, education level, employment status, and household income) were obtained. Force-entry logistic regression analysis was used. The prevalence of awareness was 31.5% (95% CI: 28.6-34.4). Factors significantly associated with awareness included sociodemographic variables, exposure to information, and knowledge of breast cancer. Being married (AOR, 95% CI: 1.75, 1.05-2.92) was positively related to awareness, while having children (0.65, 0.36-0.86) was negatively related. College graduates or those with higher levels of education (1.50, 1.01-2.22) were significantly more likely to be aware than those who had not graduated high school. Moreover, exposure to information (2.11, 1.51-2.95), and high knowledge of symptoms (2.43, 1.75-3.36) were positively associated with awareness. Finally, low knowledge of risk factors (0.30, 0.22-0.40) was negatively associated with awareness. Japanese women through internet-based study were poorly aware of the role of physical activity in breast cancer prevention. Awareness was especially low among individuals with children and higher knowledge of risk factors whereas high in married women, those with higher educational level, exposure to information, and greater knowledge of symptoms. The findings suggest that strategies to increase the awareness about the preventive role of physical activity are needed for breast cancer prevention in consideration of subgroups with low awareness.

The aim of the study was to evaluate the knowledge and behavioral risks associated with sexually transmitted infections (STIs) among the students of health professions at the University of Palermo divided into two age groups (18-22 years and 23-27 years). A self-administered questionnaire was distributed. The questionnaire is structured in three parts in addition to an introduction to socio-demographic information. The first part investigates the quality of information provided by public institutions on the subject, the second part the knowledge of contraceptive methods used to reduce the risk of contagion and the third part the knowledge of STIs and HPV vaccination. A multivariable logistic regression model was used and adjusted Odds Ratios (aOR) are presented. The sample was represented by 1022 respondents (70.8% females, 61.5% aged 18-22 years). In multivariate analyses males have a greater risk of not knowing HPV vaccine (aOR 3.52, 95% CI 2.26-5.49). The 18-22 age group has a higher risk than the 23-27 age group to think of being not sufficiently informed to avoid contagion (aOR 3.92, 95% CI 2.18-7.06), never having STIs specific tests (aOR 2.90, 95% CI 2.21-3.80), not knowing HPV vaccine (aOR 1.86, 95% CI 1.13-3.07) and not knowing that it can be administered to males (aOR 2.63, 95% CI 1.96-3.53). Based on our findings, it is necessary to implement sexual education programs for the improvement of knowledge in terms of STIs and the promotion of health. Future studies are needed to assess the effectiveness and cost of education programs that should also be addressed to young adults who do not attend university.

The inclusion of stroke education modules early in medical school curricula has resulted in improved stroke knowledge in graduate physicians. The success of these programs suggests that allied health professions programs should also consider strategies to improve stroke knowledge in students preparing for allied health careers that also require knowledge of stroke risk factors and early warning signs. Currently, little is known about stroke knowledge in students enrolled in allied health professions programs. 208 first- and second-year students enrolled in allied health programs completed a survey of stroke risk factors and early warning signs of stroke. Risk factor knowledge - 99% identified smoking as a risk factor; 67% identified diabetes; 93% identified high cholesterol; 89% identified age; and 92% identified physical inactivity. Less than 50% of the students identified all 5 risk factors. There were no differences between first- and second-year students in risk factor knowledge. Early warning signs and first response knowledge - 89% recognized sudden confusion or trouble speaking; 94% recognized sudden facial, arm, or leg weakness; 65% recognized sudden vision loss; 82% recognized sudden trouble walking; and 73% recognized sudden headache as early warning signs of stroke. Eighty-one percent recognized calling 9-1-1 as the appropriate first action. However, only 25% recognized all five early warning signs and only 20% recognized all five early warning signs and would call 9-1-1 as the first action. There were differences between first- and second-year students in recognizing 3 of 5 early warning signs and appropriate first action to call 9-1-1. Most students recognized individual stroke risk factors and early warning signs but few recognized multiple risk factors and early warning signs of stroke.

The association between HIV/AIDS-related knowledge and perception of risk for infection: a systematic review.

This systematic review tries to elucidate the association between what people know about HIV/AIDS and how they perceive their risk of infection. The initial search for articles yielded 1,595 abstracts, 16 of which met the inclusion criteria. Five studies found a positive correlation, four reported a negative correlation and seven found no association between knowledge and risk perception. It was found that the existing psychometrically sound measure of HIV/AIDS risk perception had not been used in any of the studies. The context in which the risk is assessed is pivotal to whether an association between knowledge and the perceived risk is found. Biases in judgement such as optimistic bias, psychological distancing, anchoring bias and overconfidence also explain how knowledge may fail to predict risk perception. It was concluded that the association between HIV/AIDS knowledge and risk perception might follow a continuum from positive to no association and finally to negative. The hypothesis, however, still needs to be studied further. © Royal Society for Public Health 2015.

Radiation protection is essential to enable humans to live and work safely in space. Predictions about the nature and magnitude of the risks posed by space radiation are subject to very large uncertainties. Prudent use of worst-case scenarios may impose unacceptable constraints on shielding mass for spacecraft or habitats, tours of duty of crews on Space Station, and on the radius and duration of sorties on planetary surfaces. The NASA Space Radiation Health Program has been devised to develop the knowledge required to accurately predict and to efficiently manage radiation risk. The knowledge will be acquired by means of a peer-reviewed, largely ground-based and investigator-initiated, basic science research program. The NASA Strategic Plan to accomplish these objectives in a manner consistent with the high priority assigned to the protection and health maintenance of crews will be presented.

One of NASA's goals for long duration space flight is to maintain acceptable levels of crew health, safety, and performance. One way of meeting this goal is through BRAIN, an integrated network of both human and computer elements. BRAIN will function as an advisor to mission managers by assessing the risk of inflight biomedical problems and recommending appropriate countermeasures. Described here is a joint effort among various NASA elements to develop BRAIN and the Infectious Disease Risk Assessment (IDRA) prototype. The implementation of this effort addresses the technological aspects of knowledge acquisition, integration of IDRA components, the use of expert systems to automate the biomedical prediction process, development of a user friendly interface, and integration of IDRA and ExerCISys systems. Because C language, CLIPS and the X-Window System are portable and easily integrated, they were chosen ss the tools for the initial IDRA prototype.

Epistemic uncertainties and natural hazard risk assessment - Part 1: A review of the issues

Uncertainties in natural hazard risk assessment are generally dominated by the sources arising from lack of knowledge or understanding of the processes involved. There is a lack of knowledge about frequencies, process representations, parameters, present and future boundary conditions, consequences and impacts, and the meaning of observations in evaluating simulation models. These are the epistemic uncertainties that can be difficult to constrain, especially in terms of event or scenario probabilities, even as elicited probabilities rationalized on the basis of expert judgements. This paper reviews the issues raised by trying to quantify the effects of epistemic uncertainties. Such scientific uncertainties might have significant influence on decisions that are made for risk management, so it is important to communicate the meaning of an uncertainty estimate and to provide an audit trail of the assumptions on which it is based. Some suggestions for good practice in doing so are made.

Fuzzy approach for reducing subjectivity in estimating occupational accident severity.

PubMed

Pinto, Abel; Ribeiro, Rita A; Nunes, Isabel L

2012-03-01

Quantifying or, more generally, estimating the severity of the possible consequences of occupational accidents is a decisive step in any occupational risk assessment process. Because of the lack of historic information (accident data collection and recording are incipient and insufficient, particularly in construction) and the lack of practical tools in the construction industry, the estimation/quantification of occupational accident severity is a notably arbitrary process rather than a systematic and rigorous assessment. This work proposes several severity functions (based on a safety risk assessment) to represent biomechanical knowledge with the aim of determining the severity level of occupational accidents in the construction industry and, consequently, improving occupational risk assessment quality. We follow a fuzzy approach because it makes it possible to capture and represent imprecise knowledge in a simple and understandable way for users and specialists. Copyright © 2011 Elsevier Ltd.

2013-10-01

Previous research has established that child welfare workers lack important information about child maltreatment fatalities and risk factors leading to death. Further, training has not been associated with improvements in knowledge. The authors assessed the presence of evidence-based information about child maltreatment fatalities and risk factors for death in 24 social science textbooks about child abuse and neglect or child welfare. The results indicate that basic information, such as definitions and incidence rates of child maltreatment fatalities are routinely included in social science textbooks, but information about child, parent, and household risk factors are not, and that inaccurate information is often included. Implications of the findings are discussed.

Applying Self-Determination Theory to Adolescent Sexual-Risk Behavior and Knowledge: A Structural Equation Model [Formula: see text].

2018-05-01

National health priorities identify adolescent sexual-risk behavior outcomes as research and intervention targets for mental health. Reduce sexual-risk behavioral outcomes by applying self-determination theory to focus on decision-making autonomy. This study examined late adolescents' recollections of parental autonomy support/sexual-risk communication experiences and autonomy motivation as predictors of sexual-risk behaviors/knowledge. A convenience sample ( N = 249) of 19- and 20-year-old university students completed self-report questionnaires. Structural equation modeling with latent variables examined direct/indirect effects in the hypothesized model. Parents contributed uniquely through sexual-risk communication and/or autonomy support to late adolescents' autonomous motivation. The final model evidenced acceptable fit and explained 12% of the variation in adolescent sexual-risk behavior, 7% in adolescent autonomous motivation, and 2% in adolescent sexual-risk knowledge. Psychiatric mental health nurses should conduct further research and design interventions promoting parent autonomy support and adolescent autonomous motivation to reduce sexual risk-behavior and increase sexual-risk knowledge.

A history of preeclampsia is a risk factor for the future development of hypertension and cardiovascular disease (CVD). The objective of this study was to assess, in women with prior preeclampsia, the level of knowledge regarding the link between preeclampsia and CVD, motivators for and barriers to lifestyle change and interest in a lifestyle modification program to decrease CVD risk following a pregnancy complicated by preeclampsia. Twenty women with a history of preeclampsia participated in 5 phone-based focus groups. Focus groups were recorded, transcribed, and analyzed. Qualitative content analysis was used to identify common themes across focus groups. Consensus was reached on a representative set of themes describing the data. Women with prior preeclampsia were in general unaware of the link between preeclampsia and future CVD but eager to learn about this link and motivated to achieve a healthy lifestyle. Major perceived barriers to lifestyle change were lack of time, cost of healthy foods and family responsibilities. Perceived facilitators included knowledge of the link between preeclampsia and CVD, a desire to stay healthy, and creating a healthy home for their children. Women with prior preeclampsia were interested in the idea of a web-based program focused on lifestyle strategies to decrease CVD risk in women. Women with prior preeclampsia were eager to learn about the link between preeclampsia and CVD and to take steps to reduce CVD risk. A web-based program to help women with prior preeclampsia adopt a healthy lifestyle may be an appropriate strategy for this population.

Migrant female sex workers (FSWs) are one of the most at-risk populations for HIV in China. This study demonstrates how multiple risk factors are situated and vary by types of sex work environments in a sample of 348 migrant FSWs in Beijing. Participants reported high rates of clients' refusal to use condoms (76%), unsafe sex with both clients (32%), non-paid regular partners (e.g., boyfriend or husband) (76%), and a STI symptom (79%) last year. Only 22% of FSWs had been tested for HIV. Risk factors were compared by three types of sex work environments: (1) entertainment establishments, (2) personal services sectors, and (3) street-based venues, including roadside brothels. Street-based FSWs, compared to the other FSWs, were more likely to be older, married with children, migrate from rural areas, and be arrested by police, and less likely to be educated, have contact with prevention services, be knowledgeable about HIV, and be tested for HIV. The FSWs in entertainment establishments were more likely than street-based FSWs to have reported being physically, verbally, and/or sexually abused by clients. Multiple discriminant analysis distinguished a profile of two different groups of risk factors: (1) police arrest, lack of protection from violence, access to prevention and health care, and HIV knowledge, and (2) verbal and physical abuse and clients' refusal of condom use. In the massive internal migration in China, disadvantages in economic sectors drive women to become involved in sex work. HIV prevention strategies must target socio-structural factors embedded in sex work environments. PMID:20391235

Safe radiography in scoliosis management is based on a sound knowledge of 1) the radiographic imaging process, 2) the degree of risk to the patient from radiation exposure, and 3) the radiographic requirements to both evaluate and follow patients with spine deformity. This paper is a current review of the subject and work done at the authors' centers. It includes recommendations for reducing the radiation risk while maintaining necessary diagnostic information.

The European Union Council Directive 2006/88/EC requires that risk-based surveillance (RBS) for listed aquatic animal diseases is applied to all aquaculture production businesses. The principle behind this is the efficient use of resources directed towards high-risk farm categories, animal types and geographic areas. To achieve this requirement, fish and shellfish farms must be ranked according to their risk of disease introduction and spread. We present a method to risk rank shellfish farming areas based on the risk of disease introduction and spread and demonstrate how the approach was applied in 45 shellfish farming areas in England and Wales. Ten parameters were used to inform the risk model, which were grouped into four risk themes based on related pathways for transmission of pathogens: (i) live animal movement, (ii) transmission via water, (iii) short distance mechanical spread (birds) and (iv) long distance mechanical spread (vessels). Weights (informed by expert knowledge) were applied both to individual parameters and to risk themes for introduction and spread to reflect their relative importance. A spreadsheet model was developed to determine quantitative scores for the risk of pathogen introduction and risk of pathogen spread for each shellfish farming area. These scores were used to independently rank areas for risk of introduction and for risk of spread. Thresholds were set to establish risk categories (low, medium and high) for introduction and spread based on risk scores. Risk categories for introduction and spread for each area were combined to provide overall risk categories to inform a risk-based surveillance programme directed at the area level. Applying the combined risk category designation framework for risk of introduction and spread suggested by European Commission guidance for risk-based surveillance, 4, 10 and 31 areas were classified as high, medium and low risk, respectively. © 2016 Crown copyright.

Objectives Risk modification through behavior change is critical for primary and secondary stroke prevention. Theories of health behavior identify perceived risk as an important component to facilitate behavior change; however, little is known about perceived risk of vascular events among stroke survivors. Methods The SWIFT (Stroke Warning Information and Faster Treatment) study includes a prospective population-based ethnically diverse cohort of ischemic stroke and transient ischemic attack survivors. We investigate the baseline relationship between demographics, health beliefs, and knowledge on risk perception. Regression models examined predictors of inaccurate perception. Results Only 20% accurately estimated risk, 10% of the participants underestimated risk, and 70% of the 817 study participants significantly overestimated their risk for a recurrent stroke. The mean perceived likelihood of recurrent ischemic stroke in the next 10 years was 51 ± 7%. We found no significant differences by race-ethnicity with regard to accurate estimation of risk. Inaccurate estimation of risk was associated with attitudes and beliefs [worry (p < 0.04), fatalism (p < 0.07)] and memory problems (p < 0.01), but not history or knowledge of vascular risk factors. Conclusion This paper provides a unique perspective on how factors such as belief systems influence risk perception in a diverse population at high stroke risk. There is a need for future research on how risk perception can inform primary and secondary stroke prevention. Copyright © 2011 S. Karger AG, Basel PMID:21894045

Bayesian Networks Improve Causal Environmental Assessments for Evidence-Based Policy.

Carriger, John F; Barron, Mace G; Newman, Michael C

2016-12-20

Rule-based weight of evidence approaches to ecological risk assessment may not account for uncertainties and generally lack probabilistic integration of lines of evidence. Bayesian networks allow causal inferences to be made from evidence by including causal knowledge about the problem, using this knowledge with probabilistic calculus to combine multiple lines of evidence, and minimizing biases in predicting or diagnosing causal relationships. Too often, sources of uncertainty in conventional weight of evidence approaches are ignored that can be accounted for with Bayesian networks. Specifying and propagating uncertainties improve the ability of models to incorporate strength of the evidence in the risk management phase of an assessment. Probabilistic inference from a Bayesian network allows evaluation of changes in uncertainty for variables from the evidence. The network structure and probabilistic framework of a Bayesian approach provide advantages over qualitative approaches in weight of evidence for capturing the impacts of multiple sources of quantifiable uncertainty on predictions of ecological risk. Bayesian networks can facilitate the development of evidence-based policy under conditions of uncertainty by incorporating analytical inaccuracies or the implications of imperfect information, structuring and communicating causal issues through qualitative directed graph formulations, and quantitatively comparing the causal power of multiple stressors on valued ecological resources. These aspects are demonstrated through hypothetical problem scenarios that explore some major benefits of using Bayesian networks for reasoning and making inferences in evidence-based policy.

To assess the knowledge of stroke in the general public in the Gulf Cooperation Council (GCC) countries. The Arabian Gulf is a rapidly developing part of the world with major changes in the lifestyle that can increase the risk of stroke. To design effective stroke treatment and prevention strategies, an assessment of the public knowledge of stroke is required. A cross-sectional community-based survey was conducted at primary health care centers (PHCs), in urban and semi-urban areas, of the GCC countries (Qatar, Saudi Arabia, Kuwait, Bahrain, the United Arab Emirates, Oman) on the level of stroke awareness in the general public. Health care workers completed 3,750 face-to-face interviews. 1,089 (29.0%) were familiar with the term 'stroke', and 29.3% considered the age group 30-50 at the highest risk for stroke. The commonest risk factors identified were hypertension (23.1%) and smoking (27.3%). People who did not know the term stroke had a higher incidence of diabetes, hypertension, and had more than one risk factor (p < 0.05). The most frequently identified stroke symptoms were weakness (23%) and speech problems (21.7%). Of those who recognized stroke, blockage of blood vessels was identified as the commonest cause of stroke (22%) followed by tension/worrying (20%). Doctors and nurses were regarded as the best source of stroke information (70%). In the univariate comparison, younger age (p < 0.001), higher level of education (p < 0.001), and female gender (p = 0.008) better predicted stroke recognition. In a multivariate logistic regression analysis, the level of education, monthly income and smoking were independent variables predicting stroke knowledge. The majority of the patients had not even heard the term stroke. Stroke knowledge was poorest among the groups that were at the highest risk for stroke. Stroke education has to focus on the high-risk groups, particularly the younger population. The health care workers at the PHCs and hospitals will need instructions on providing stroke information to the public. The level of knowledge of stroke risk factors and symptoms emphasizes the need for stroke education efforts in the community. (c) 2008 S. Karger AG, Basel.

Recreational and subsistence angling are important aspects of urban culture for much of North American where people are concentrated near the coasts or major rivers. Yet there are fish and shellfish advisories for many estuaries, rivers, and lakes, and these are not always heeded. This paper examines fishing behavior, sources of information, perceptions, and compliance with fishing advisories as a function of ethnicity for people fishing in the Newark Bay Complex of the New York-New Jersey Harbor. The authors test the null hypothesis that there were no ethnic differences in sources of information, perceptions of the safety of fish consumption,more » and compliance with advisories. There were ethnic differences in consumption rates, sources of information about fishing, knowledge about the safety of the fish, awareness of fishing advisories or of the correct advisories, and knowledge about risks for increased cancer and to unborn and young children. In general, the knowledge base was much lower for Hispanics, was intermediate for blacks, and was greatest for whites. When presented with a statement about the potential risks from eating fish, there were no differences in their willingness to stop eating fish or to encourage pregnant women to stop. These results indicate a willingness to comply with advisories regardless of ethnicity, but a vast difference in the base knowledge necessary to make an informed risk decisions about the safety of fish and shellfish. Although the overall median income level of the population was in the $25,000--34,999 income category, for Hispanics it was on the border between $15,000--24,999 and $25,000--34,999.« less

Participatory Geographic Information Systems (PGIS) can integrate participatory methodologies with geo-spatial technologies for the representation of characteristic of particular place. Over the last decade, researchers use this method to integrate the local knowledge of community within a GIS and Society conceptual framework. Participatory GIS are tailored to answer specific geographic questions at the local level and their modes of implementation vary considerably across space, ranging from field-based, qualitative approaches to more complex web-based applications. These broad ranges of techniques, PGIS are becoming an effective methodology for incorporating community local knowledge into complex spatial decision-making processes. The objective of this study is to reduce the soil erosion by formulating the general rule for the soil conservation by participation of the stakeholders. The poster was prepared by satellite image, topographic map and Arc GIS software including the local knowledge. The data were collected from the focus group discussion and the individual questionnaire for incorporate the local knowledge and use it to find the risk map on the basis of economic, social and manageable physical factors for the sensitivity analysis. The soil erosion risk map is prepared by the physical factors Rainfall-runoff erosivity, Soil erodibility, Slope length, Slope steepness, Cover-management, Conservation practice using RUSLE model. After the comparison and discussion among stakeholders, researcher and export group, and the soil erosion risk map showed that socioeconomic, social and manageable physical factors management can reduce the soil erosion. The study showed that the preparation of the poster GIS map and implement this in the watershed area could reduce the soil erosion in the study area compared to the existing national policy.

Homelessness is a critical social issue, both a product of, and contributing to, poor mental and physical health. Over 150,000 young Canadians live on the streets. Homeless youth experience a high incidence of infectious diseases, many of which are vaccine preventable. Early departure from school and limited access to public health services makes them a particularly vulnerable high-risk group. This study explores challenges to obtaining essential vaccines experienced by homeless youth. A qualitative research study to explore knowledge, attitudes, beliefs, and experiences surrounding immunization of hard-to-reach homeless youth was designed. Participants were recruited for focus groups from Phoenix House and Shelter, a non-profit, community-based organization assisting homeless youth in Halifax, Nova Scotia, Canada. An experienced facilitator guided the recorded discussions. Transcripts of audiotapes were analyzed using a constant comparative method until data revealed a set of exemplars and themes that best captured participants' knowledge, attitudes, beliefs and experiences surrounding immunization and infectious diseases. Important themes emerged from our analysis. Considerable variability in knowledge about immunization and vaccine preventable diseases was found. The homeless youth in the study had limited awareness of meningitis in contrast to a greater knowledge about sexually transmitted infections and influenza, gained during the H1N1/09 public health campaign. They recognized their poverty as a risk for contracting infectious diseases, along with their inability to always employ known strategies to prevent infectious diseases, due to circumstances. They showed considerable insight into the detrimental effects of poor hygiene, sleeping locations and risk behaviour. Interviewed homeless youth regarded themselves as good compliers of health professional advice and offered valuable suggestions to improve immunization in their population. To provide effective public health interventions, it is necessary to consider the knowledge, attitudes, beliefs, and experiences of hard to reach, high risk groups. Our study shows that homeless youth are interested and capable in discussing immunization. Active targeting of homeless youth for public health immunization programs is needed. Working collaboratively with non-profit organizations that assist homeless youth provides an opportunity to increase their knowledge of infectious risks and to improve immunization strategies in this vulnerable group.

2017-01-01

Patients with rheumatoid arthritis are at increased risk for cardiovascular disease. The prerequisites for reducing the risk of cardiovascular disease are adequate levels of knowledge and being aware of the risk. In this study, the levels of knowledge about cardiovascular disease among patients with rheumatoid arthritis and the perception were evaluated in relation to their actual 10-year risk of cardiovascular disease. This cross-sectional study of 200 patients with rheumatoid arthritis was conducted in a university-affiliated hospital in South Korea. The patients' actual risk of cardiovascular disease was estimated using the Framingham Risk Score. The most common risk factor was physical inactivity, with 77% of the patients not engaging in regular exercise. The patients lacked knowledge about the effects of physical inactivity and anti-inflammatory medication on the development of cardiovascular disease. Misperceptions about the risk of cardiovascular disease were common, i.e., 19.5% of the patients underestimated their risk and 41% overestimated. Hypertension, diabetes, obesity, and smoking were the most prevalent among the patients who underestimated their risk, and these same patients had the lowest level of knowledge about cardiovascular disease. This study demonstrated the rheumatoid arthritis patients' lack of knowledge about the effects of physical inactivity and anti-inflammatory medications on the development of cardiovascular disease, and their misperception of cardiovascular risk was common. As a preventive measure, educational programs about cardiovascular disease should be tailored specifically for patients with rheumatoid arthritis, and behavioral interventions, including routine exercise, should be made available at the time of diagnosis.

Two education interventions involving personalized messages after nutrition screening in older adults were compared to determine changes in nutrition knowledge and risk behaviour. Of 150 older adults randomly selected from a local seniors' centre, 61 completed baseline screening and a demographic and nutrition knowledge questionnaire and were randomized to one of two groups. Group A received personalized letters plus an educational booklet, and Group B received personalized letters only. All materials were sent through the mail. Forty-four participants completed post-test questionnaires to determine change in knowledge and risk behaviour. Both groups had reduced nutrition risk scores and increased knowledge scores at post-test. After the intervention, a significant difference was observed in knowledge change by treatment group. Group A participants experienced greater gains in knowledge, with a mean gain of 5.43 points, than did those in Group B, who had a mean gain of 1.36 points (p=0.018). Screening and education with print materials have the potential to change risk behaviour and nutrition knowledge in older adults. A specially designed booklet on older adults' nutrition risk factors plus a personalized letter provide an effective education strategy for older adults after screening.

The purpose of this study was to assess which knowledge deficits and dietary habits in an urban pediatric emergency department (ED) population are risk factors for obesity. This cross-sectional study in an urban pediatric ED used a modified version of the Diet and Health Knowledge Survey, an in-person interview questionnaire, to collect data on demographics, dietary knowledge, and practices. All patients aged 2 to 17 years were enrolled in the study over a 4-month period. Subjects were excluded if they were in extremis, pregnant, incarcerated, institutionalized, considered an emancipated minor, or consumed only a modified consistency diet. One hundred seventy-nine subjects were enrolled in this study. Based on body mass index, the prevalence of obesity in our study population was 24%. Parents with obese children answered a mean of 62.9% (95% confidence interval, 60.4%-65.5%) of knowledge questions correctly, whereas all others scored 60.3% (95% confidence interval, 58.3%-62.3%) correctly. Based on the univariate analysis, 10 predictors met inclusion criteria into logistic regression analysis: screen time (P = 0.03), race (P = 0.08), sex (P = 0.04), parental education (P = 0.08), parental estimation that child is overweight (P < 0.0001), parental estimation that child is underweight (P = 0.003), trimming fat from meat (P = 0.06), soft-drink consumption (P = 0.03), exercise (P = 0.07), and chip consumption (P = 0.04). In a multivariate analysis, only male sex, regularly trimming fat from meat, and parental assessment of obesity were independently associated with obesity. Knowledge deficiencies regarding healthy nutrition among parents in an urban pediatric ED population were not significantly associated with having obese children; however, specific habits were. Emergency physicians may provide a valuable role in identification and brief behavioral intervention in high-risk populations during the current epidemic of childhood obesity.

Natalizumab (NAT) is associated with the risk of progressive multifocal leukoencephalopathy (PML). Risk stratification algorithms have been developed, however, without detectable reduction of PML incidence. To evaluate to which extent patients and physicians understand and accept risks associated with NAT treatment. Prospective observational cohort study in German MS centers (n=73) among NAT-treated MS patients (n=801) and their neurologists (n=99). Patients included in this study had mean disease duration of 10.2years and a mean NAT treatment duration of 24months. More than 90% of patients and physicians voted for shared decision making or an informed choice decision making approach. Patients and physicians perceived a similar threat from MS as serious disease and both overestimated treatment benefits from NAT based on trial data. Men perceived MS more severe than women and perception of seriousness increased with age in both groups and in patients as well with increasing disability. Although patients evaluated their PML risk higher, their risk acceptance was significantly higher than of their neurologists. Risk stratification knowledge was good among neurologists and significantly lower among patients. While patients and physicians seem to have realistic risk perception of PML and knowledge of risk stratification concepts, the threat of MS and the perception of treatment benefits may explain the ongoing high acceptance of PML risk.

Objective: The purpose of this study was to compare CT image quality for evaluating urolithiasis using filtered back projection (FBP), statistical iterative reconstruction (IR) and knowledge-based iterative model reconstruction (IMR) according to various scan parameters and radiation doses. Methods: A 5 × 5 × 5 mm3 uric acid stone was placed in a physical human phantom at the level of the pelvis. 3 tube voltages (120, 100 and 80 kV) and 4 current–time products (100, 70, 30 and 15 mAs) were implemented in 12 scans. Each scan was reconstructed with FBP, statistical IR (Levels 5–7) and knowledge-based IMR (soft-tissue Levels 1–3). The radiation dose, objective image quality and signal-to-noise ratio (SNR) were evaluated, and subjective assessments were performed. Results: The effective doses ranged from 0.095 to 2.621 mSv. Knowledge-based IMR showed better objective image noise and SNR than did FBP and statistical IR. The subjective image noise of FBP was worse than that of statistical IR and knowledge-based IMR. The subjective assessment scores deteriorated after a break point of 100 kV and 30 mAs. Conclusion: At the setting of 100 kV and 30 mAs, the radiation dose can be decreased by approximately 84% while keeping the subjective image assessment. Advances in knowledge: Patients with urolithiasis can be evaluated with ultralow-dose non-enhanced CT using a knowledge-based IMR algorithm at a substantially reduced radiation dose with the imaging quality preserved, thereby minimizing the risks of radiation exposure while providing clinically relevant diagnostic benefits for patients.

Purpose: Population-based studies suggest underuse of radiation therapy, especially after mastectomy. Because radiation oncology is a referral-based specialty, knowledge and attitudes of upstream providers, specifically surgeons, may influence patients' decisions regarding radiation, including whether it is even considered. Therefore, we sought to evaluate surgeons' knowledge of pertinent risk information, their patterns of referral, and the correlates of surgeon knowledge and referral in specific breast cancer scenarios. Methods and Materials: We surveyed a national sample of 750 surgeons, with a 67% response rate. We analyzed responses from those who had seen at least 1 breast cancer patient in the past yearmore » (n=403), using logistic regression models to identify correlates of knowledge and appropriate referral. Results: Overall, 87% of respondents were general surgeons, and 64% saw >10 breast cancer patients in the previous year. In a scenario involving a 45-year-old undergoing lumpectomy, only 45% correctly estimated the risk of locoregional recurrence without radiation therapy, but 97% would refer to radiation oncology. In a patient with 2 of 20 nodes involved after mastectomy, 30% would neither refer to radiation oncology nor provide accurate information to make radiation decisions. In a patient with 4 of 20 nodes involved after mastectomy, 9% would not refer to radiation oncology. Fewer than half knew that the Oxford meta-analysis revealed a survival benefit from radiation therapy after lumpectomy (45%) or mastectomy (32%). Only 16% passed a 7-item knowledge test; female and more-experienced surgeons were more likely to pass. Factors significantly associated with appropriate referral to radiation oncology included breast cancer volume, tumor board participation, and knowledge. Conclusions: Many surgeons have inadequate knowledge regarding the role of radiation in breast cancer management, especially after mastectomy. Targeted educational interventions may improve the quality of care.« less

Balancing treatment benefits and risks is part of a shared decision-making process before initiating any treatment in multiple sclerosis (MS). Patients understand, appreciate and profit from evidence-based patient information (EBPI). While these processes are well known, long-term risk awareness and risk processing of patients has not been studied. Mitoxantrone treatment in MS is associated with long-term major potential harms - leukaemia (LK) and cardiotoxicity (CT). The risk knowledge and perception among patients currently or previously treated with mitoxantrone is unknown. The objective of this article is to conduct a retrospective cohort study in greater Hamburg, Germany, to estimate risk awareness and perception in MS patients treated with mitoxantrone. MS patients with at least one dose of mitoxantrone between 1991 and 2010 from six major MS centres in greater Hamburg received a questionnaire assessing risk awareness and perception as well as a written EBPI about mitoxantrone-associated LK and CT. Fifty-one per cent in the cohort of n = 575 patients returned the questionnaire. Forty per cent correctly estimated the risk of LK (CT 16%); 56% underestimated the risk (CT 82%). Reading the information increased the accuracy of LK risk estimation, and patients did not report an increase of worries. The EBPI was appreciated and recommended by 85%. Risk awareness of mitoxantrone-treated patients is insufficient, but can be increased by EBPI without increasing worries. Continued patient information during and after treatment should be implemented in management algorithms.

High-speed commercial flight transportation is being studied for intercontinental operations in the 21st century, the projected operational characteristics for these aircraft are examined, the radiation environment as it is now known is presented, and the relevant health issues are discussed. Based on a critical examination of the data, a number of specific issues need to be addressed to ensure an adequate knowledge of the ionizing radiation health risks of these aircraft operations. Large uncertainties in our knowledge of the physical fields for high-energy neutrons and multiply-charged ion components need to be reduced. Improved methods for estimating risks in prenatal exposure need to be developed. A firm basis for solar flare monitoring and forecasting needs to be developed with means of exposure abatement.

Arranging marriage; negotiating risk: genetics and society in Qatar.

This paper considers how the globalized discourse of genetic risk in cousin marriage is shaped, informed and taken up in local moral worlds within the context of Qatar. This paper investigates the way Qataris are negotiating the discourse on genetics and risk. It is based on data from ongoing ethnographic research in Qatar and contributes to anthropological knowledge about this understudied country. Participants were ambivalent about genetic risks and often pointed to other theories of causation in relation to illness and disability. The discourse on genetic risk associated with marrying in the family was familiar, but for some participants the benefits of close marriage outweighed potential risks. Furthermore, the introduction of mandatory pre-marital screening gave participants confidence that risks were monitored and minimized.

As professional psychology training programs and continuing education have moved toward competency based approaches, it has become equally important to develop uniform, evidence-based approaches for suicide risk assessment and management. The present article presents a workshop curriculum based on established core competencies in suicide risk assessment and management. Drawing on theories suicide risk formation, the workshop features an integration of didactic, process, and experiential components. We present pilot data from 2 small group workshops (n = 17): 1 from a clinical psychology doctoral program and 1 from a university counseling center. Workshop participation yielded increases in (a) the ability to recognize appropriate clinician responses to suicidal client statements, (b) self-perceptions of general capacity to interface with suicidal patients and mastery of the 10 core competencies, (c) factual knowledge concerning suicide risk assessment and management, and (d) the self-rated ability to assess and manage a suicidal patient. We discuss statistical and generalizability limitations as well as implications for future modification, implementation, and provision of this training method. © 2016 Wiley Periodicals, Inc.

However, few interventions have been designed to meet the needs of this "forgotten" population. The article describes the systematic development of a theory-based, culturally-tailored, gender-specific, barbershop-based HIV risk reduction intervention for heterosexual African American men ages 18 to 24. The process included developing a community advisory board, selecting a guiding theoretical framework, incorporating community-based participatory research principles, and conducting formative research with African American males, barbers, and barbershop owners. The result was Shape Up: Barbers Building Better Brothers, a 2-day, HIV risk reduction intervention focused on increasing HIV knowledge and condom use and reducing the number of sexual partners. Intervention sessions were facilitated by barbers who used iPads to deliver the content. As a high-risk population, this intervention has great public health significance for the health of African American men and their sexual partners. © 2016 Society for Public Health Education.

The aim of this study was to assess the knowledge of Omani adults regarding conventional coronary heart disease (CHD) risk factors and to identify demographic variables associated with these knowledge levels. This descriptive cross-sectional pilot study was carried out among a convenience sample of 130 adults attending a health awareness fair held in a local shopping mall in Muscat, Oman, in November 2012. A modified version of the Heart Disease Facts Questionnaire in both English and Arabic was used to assess knowledge of CHD risk factors. Scores were calculated by summing the correct answers for each item (range: 0-21). Inadequate knowledge was indicated by a mean score of <70%. Descriptive and multivariate logistic regression analyses were performed to establish the participants' knowledge levels and identify associated demographic variables. A total of 114 subjects participated in the study (response rate: 87.7%). Of these, 69 participants (60.5%) had inadequate mean CHD knowledge scores. Knowledge of CHD risk factors was significantly associated with body mass index (odds ratio [OR] = 0.739; P = 0.023), marital status (OR = 0.057; P = 0.036) and education level (OR = 9.243; P = 0.006). Low knowledge levels of CHD risk factors were observed among the studied community sample in Oman; this is likely to limit the participants' ability to engage in preventative practices. These findings support the need for education programmes to enhance awareness of risk factors and prevention of CHD in Oman.

The use of e-cigarettes and other vaping devices among adolescents is an urgent public health problem due to the concern about adolescent exposure to nicotine. This study examined: (1) adolescents’ knowledge and beliefs about e-cigarette risks; and (2) whether knowledge and risk beliefs were associated with e-cigarette use. N = 69 adolescents completed a cross-sectional survey about e-cigarette knowledge, attitudes (i.e., risk beliefs), and behavior (KAB). Nearly half (47%) of the sample reported ever using e-cigarettes. The majority of adolescents knew about many of the risks of e-cigarettes, with no differences between never- and ever-users. However, risk beliefs, such as worrying about health risks of using e-cigarettes, varied across groups. Compared to never-users, e-cigarette ever-users were significantly less likely to worry about e-cigarette health risks, less likely to think that e-cigarettes would cause them negative health consequences, and less likely to believe that e-cigarette use would lead to addiction. In a multivariable logistic regression, prior combustible cigarette use, mother’s education, and addiction risk beliefs about e-cigarettes emerged as significant predictors of adolescents’ e-cigarette use. This study reveals that while knowledge is not associated with adolescent e-cigarette use, risk beliefs do predict use. PMID:29690606

Decision support tools for the assessment and management of breast cancer risk may improve uptake of prevention strategies. End-user input in the design of such tools is critical to increase clinical use. Before developing such a computerized tool, we examined clinicians' practice and future needs. Twelve breast surgeons, 12 primary care physicians and 5 practice nurses participated in 4 focus groups. These were recorded, coded, and analyzed to identify key themes. Participants identified difficulties assessing risk, including a lack of available tools to standardize practice. Most expressed confidence identifying women at potentially high risk, but not moderate risk. Participants felt a tool could especially reassure young women at average risk. Desirable features included: evidence-based, accessible (e.g. web-based), and displaying absolute (not relative) risks in multiple formats. The potential to create anxiety was a concern. Development of future tools should address these issues to optimize translation of knowledge into clinical practice. Copyright © 2014 Elsevier Ltd. All rights reserved.

Use of documentary sources on past flood events for flood risk management and land planning

NASA Astrophysics Data System (ADS)

Cœur, Denis; Lang, Michel

2008-09-01

The knowledge of past catastrophic events can improve flood risk mitigation policy, with a better awareness against risk. As such historical information is usually available in Europe for the past five centuries, historians are able to understand how past society dealt with flood risk, and hydrologists can include information on past floods into an adapted probabilistic framework. In France, Flood Risk Mitigation Maps are based either on the largest historical known flood event or on the 100-year flood event if it is greater. Two actions can be suggested in terms of promoting the use of historical information for flood risk management: (1) the development of a regional flood data base, with both historical and current data, in order to get a good feedback on recent events and to improve the flood risk education and awareness; (2) the commitment to keep a persistent/perennial management of a reference network of hydrometeorological observations for climate change studies.

Diagnosis of hereditary colorectal cancer syndromes requires clinical suspicion and knowledge of such syndromes. Lynch syndrome is the most common cause of hereditary colorectal cancer. Other less common causes include familial adenomatous polyposis (FAP), Peutz-Jeghers syndrome (PJS), juvenile polyposis syndrome, and others. There have been a growing number of clinical and molecular tools used to screen and test at risk individuals. Screening tools include diagnostic clinical criteria, family history, genetic prediction models, and tumor testing. Patients who are high risk based on screening should be referred for genetic testing. PMID:23730221

Knowledge and confidence of Australian emergency department clinicians in managing patients with mental health-related presentations: findings from a national qualitative study

PubMed Central

2013-01-01

Background Mental health related presentations are common in Australian Emergency Departments (EDs). We sought to better understand ED staff knowledge and levels of confidence in treating people with mental health related problems using qualitative methods. Methods This was a qualitative learning needs analysis of Australian emergency doctors and nurses regarding the assessment and management of mental health presentations. Participants were selected for semi-structured telephone interview using criterion-based sampling. Recruitment was via the Australasian College for Emergency Medicine and College of Emergency Nursing Australasia membership databases. Interviews were audio-recorded and transcribed verbatim. Thematic framework analysis was used to identify perceived knowledge gaps and levels of confidence among participants in assessing and managing patients attending EDs with mental health presentations. Results Thirty-six staff comprising 20 doctors and 16 nurses consented to participate. Data saturation was achieved for four major areas where knowledge gaps were reported. These were: assessment (risk assessment and assessment of mental status), management (psychotherapeutic skills, ongoing management, medication management and behaviour management), training (curriculum and rotations), and application of mental health legislation. Participants’ confidence in assessing mental health patients was affected by environmental, staff, and patient related factors. Clinicians were keen to learn more about evidence based practice to provide better care for this patient group. Areas where clinicians felt the least confident were in the effective assessment and management of high risk behaviours, providing continuity of care, managing people with dual diagnosis, prescribing and effectively managing medications, assessing and managing child and adolescent mental health, and balancing the caseload in ED. Conclusion Participants were most concerned about knowledge gaps in risk assessment, particularly for self-harming patients, violent and aggressive patients and their management, and distinguishing psychiatric from physical illness. Staff confidence was enhanced by better availability of skilled psychiatric support staff to assist in clinical decision-making for complex cases and via the provision of a safe ED environment. Strategies to enhance the care of patients with mental health presentations in Australian emergency departments should address these gaps in knowledge and confidence. PMID:23317351

Cardiovascular diseases are responsible for the largest burden of global mortality. The study of the degree of knowledge of their population risk factors and cardiovascular risk is a priority preventive strategy. A cross-sectional study with 369 people was performed. The sociodemographic variables were cardiovascular risk and perception as well as physical and anthropometric factors. The risk was stratified with the SCORE table. A total of 49.6% were men and 50.4% were women. The proportion of diagnosis was 23.8% in HTA, 39% in hypercholesterolemia, 31.4% in smoking, 26.3% in obesity and 4.6% in diabetes. Concordance between perceived and real cardiovascular risk was very weak. The population has good knowledge about diabetes and acceptable knowledge about hypertension, and hypercholesterolemia but knowledge in prediabetic states and perception of the associated cardiovascular risk is low.

An efficient and effective risk management required a systematic and proper methodology besides knowledge and experience. However, if the risk management is not discussed from the starting of the project, this duty is notably complicated and no longer efficient. This paper presents the adoption of Building Information Modelling (BIM) in project planning risk management. The objectives is to identify the traditional risk management practices and its function, besides, determine the best function of BIM in risk management and investigating the efficiency of adopting BIM-based risk management during the project planning phase. In order to obtain data, a quantitative approach is adopted in this research. Based on data analysis, the lack of compliance with project requirements and failure to recognise risk and develop responses to opportunity are the risks occurred when traditional risk management is implemented. When using BIM in project planning, it works as the tracking of cost control and cash flow give impact on the project cycle to be completed on time. 5D cost estimation or cash flow modeling benefit risk management in planning, controlling and managing budget and cost reasonably. There were two factors that mostly benefit a BIM-based technology which were formwork plan with integrated fall plan and design for safety model check. By adopting risk management, potential risks linked with a project and acknowledging to those risks can be identified to reduce them to an acceptable extent. This means recognizing potential risks and avoiding threat by reducing their negative effects. The BIM-based risk management can enhance the planning process of construction projects. It benefits the construction players in various aspects. It is important to know the application of BIM-based risk management as it can be a lesson learnt to others to implement BIM and increase the quality of the project.

Biological effects of space radiation and risk mitigation are strategic knowledge gaps for the Evolvable Mars Campaign. The current epidemiology-based NASA Space Cancer Risk (NSCR) model contains large uncertainties (HAT #6.5a) due to lack of information on the radiobiology of galactic cosmic rays (GCR) and lack of human data. The use of experimental models that most accurately replicate the response of human tissues is critical for precision in risk projections. Our proposed study will compare DNA damage, histological, and cell kinetic parameters after irradiation in normal 2D human cells versus 3D tissue models, and it will use a multi-scale computational model (CHASTE) to investigate various biological processes that may contribute to carcinogenesis, including radiation-induced cellular signaling pathways. This cross-disciplinary work, with biological validation of an evolvable mathematical computational model, will help reduce uncertainties within NSCR and aid risk mitigation for radiation-induced carcinogenesis.

Graphics are increasingly used to represent the spread of infectious diseases (e.g., influenza, Zika, Ebola); however, the impact of using graphics to adequately inform the general population is unknown. To examine whether three ways of visually presenting data (heat map, dot map, or picto-trendline)-all depicting the same information regarding the spread of a hypothetical outbreak of influenza-influence intent to vaccinate, risk perception, and knowledge. Survey with participants randomized to receive a simulated news article accompanied by one of the three graphics that communicated prevalence of influenza and number of influenza-related deaths. International online survey. 16,510 adults living in 11 countries selected using stratified random sampling based on age and gender. After reading the article and viewing the presented graphic, participants completed a survey that measured interest in vaccination, perceived risk of contracting disease, knowledge gained, interest in additional information about the disease, and perception of the graphic. Heat maps and picto-trendlines were evaluated more positively than dot maps. Heat maps were more effective than picto-trendlines and no different from dot maps at increasing interest in vaccination, perceived risk of contracting disease, and interest in additional information about the disease. Heat maps and picto-trendlines were more successful at conveying knowledge than dot maps. Overall, heat maps were the only graphic to be superior in every outcome. Results are based on a hypothetical scenario. Heat maps are a viable option to promote interest in and concern about infectious diseases. Published by Elsevier Ltd.

Mental health problems often go undiagnosed or unaddressed until a crisis or extreme event brings the problem to the forefront. Youth are particularly at risk for lack of identification and treatment in regard to mental health issues. This article describes an advanced nursing practice mental health initiative for at-risk teenage girls based on Hildegard Peplau's nursing theory, group process, and healing through holistic health approaches. A support group, RICHES, was developed with focus on core components of relationships, identity, communication, health, esteem, and support. The acronym RICHES was chosen as the name of the support group. Selected themes and issues addressed in this school-based support group are illustrated in case vignettes. Through a collaborative approach with the community and school, this practice initiative presents a unique healing process that extends knowledge in the realm of intervention with at-risk teenage girls. Further research is needed on the efficacy of support groups to modify risk factors and to address goals for primary prevention in at-risk teenage girls. © The Author(s) 2014.

Influence of scientific-technical literacy on consumers' behavioural intentions regarding new food.

The application of genetic engineering to agriculture has led to an important and controversial innovation in the food sector, so-called Genetically Modified (GM) food. A great deal of literature has studied cognitive and attitudinal factors conditioning consumers' acceptance of GM food, knowledge being one of the most inconsistent variables. Notwithstanding, some authors suggest closer attention should be paid to "science literacy", even more so than knowledge. This paper studies the potential role of consumer literacy fields - i.e. consumer scientific-technical or social-humanistic literacy - in determining consumer choice behaviour towards GM foods. We analyse the strength of the moderating effects produced by consumer university training in some of the most important factors which influence consumers' innovative product acceptance, such as perceived benefits and risks, attitudes to GM technology, trust in institutions or knowledge. The research is performed in southern Spain, using a variance-based technique called Structural Equation Modelling by Partial Least Squares (PLSs). The results show that perceived benefits and risks play a significant role in shaping behavioural intentions towards GM food, the attitude to GM technology being the main driver of consumers' beliefs about risks and benefits. Additionally, behavioural intentions display some differences between the scientific-technical and social-humanistic literacy fields, the variables of trust in institutions and knowledge registering the most striking differences.

NASA Astrophysics Data System (ADS)

Eckels Anderson, Chessa

This study contributed to the body of research that supports a holistic model of afterschool learning through the design of an afterschool intervention that benefits elementary school students of low socioeconomic status. This qualitative study evaluated a science focused afterschool curriculum that was designed using principles from Risk and Resiliency Theory, academic motivation theories, science core ideas from the Next Generation Science Standards, and used environmental education philosophy. The research question of this study is: how does an outdoor and STEM based afterschool program impact at-risk students' self-efficacy, belonging and engagement and ability to apply conceptual knowledge of environmental science topics? The study collected information about the participants' affective experiences during the intervention using structured and ethnographic observations and semi-structured interviews. Observations and interviews were coded and analyzed to find patterns in participants' responses. Three participant profiles were developed using the structured observations and ethnographic observations to provide an in depth understanding of the participant experience. The study also assessed the participants' abilities to apply conceptual understanding of the program's science topics by integrating an application of conceptual knowledge task into the curriculum. This task in the form of a participant project was assessed using an adapted version of the Portland Metro STEM Partnership's Application of Conceptual Knowledge Rubric. Results in the study showed that participants demonstrated self-efficacy, a sense of belonging and engagement during the program. Over half of the participants in the study demonstrated a proficient understanding of program concepts. Overall, this holistic afterschool program demonstrated that specific instructional practices and a multi-modal science curriculum helped to support the social and emotional needs of at-risk children.

Breast cancer (BC) continues to be a major cause of morbidity and mortality among women throughout the world and in Iran. Lack of awareness and early detection program in developing country is a main reason for escalating the mortality. The present research was conducted to assess the Iranian women's level of knowledge about breast cancer risk factors, early warning signs, and therapeutic and screening approaches, and their correlated determinants. In a cross-sectional study, 2250 women before participating at a community based screening and public educational program in an institute of cancer research in Isfahan, Iran, in 2012 were investigated using a self-administered questionnaire about risk factors, early warning signs, and therapeutic and screening approaches of BC. Latent class regression as a comprehensive statistical method was used for evaluating the level of knowledge and its correlated determinants. Only 33.2%, 31.9%, 26.7%, and 35.8% of study participants had high awareness levels about screening approaches, risk factors, early warning signs and therapeutic modalities of breast cancer, respectively, and majority had poor to moderate knowledge levels. Most effective predictors of high level of awareness were higher educational qualifications, attending in screening and public educational programs, personal problem, and family history of BC, respectively. Results of current study indicated that the levels of awareness among study population about key elements of BC are low. These findings reenforce the continuing need for more BC education through conducting public and professional programs that are intended to raise awareness among younger, single women and those with low educational attainments and without family history.

University students and HIV in Namibia: an HIV prevalence survey and a knowledge and attitude survey

Background With an overall adult HIV prevalence of 15.3%, Namibia is facing one of the largest HIV epidemics in Africa. Young people aged 20 to 34 years constitute one of the groups at highest risk of HIV infection in Namibia. However, little is known about the impact of HIV on this group and its access to healthcare. The purpose of this study was to estimate HIV prevalence, to assess the knowledge of and attitudes towards HIV/AIDS, and to assess access to healthcare among university students in Namibia. Methods We assessed HIV/AIDS knowledge and attitudes, HIV prevalence and access to healthcare among students at the Polytechnic of Namibia and the University of Namibia. HIV prevalence was tested through anonymous oral fluid-based tests. Results Half (n = 2790/5568) of the university students and 45% (n = 2807/6302) of the Polytechnic students participated in the knowledge and attitudes surveys. HIV/AIDS knowledge was reasonable, except for misperceptions about transmission. Awareness of one's own HIV status and risks was low. In all, 55% (n = 3055/5568) of university students and 58% (n = 3680/6302) of Polytechnic students participated in the HIV prevalence survey; 54 (1.8%) university students and 103 (2.8%) Polytechnic students tested HIV positive. Campus clinics were not the major providers of healthcare to the students. Conclusions Meaningful strategies addressing the gap between knowledge, attitude and young people's perception of risk of HIV acquisition should be implemented. HIV prevalence among Namibian university students appears relatively low. Voluntary counselling and testing should be stimulated. Efforts should be made to increase access to healthcare through the campus clinics. PMID:22353579

To evaluate the effect of Hip Hop Stroke, a school-based multimedia musical stroke literacy intervention that targets children aged 8-12 in high-risk minority communities, on the long-term learning of stroke knowledge. We enrolled a cohort of 104 fifth and sixth grade children from 2 schools in Central Harlem into a single course of Hip Hop Stroke (3 1-hour classroom sessions, delivered over 3 consecutive days). Tests evaluating knowledge of stroke symptoms and behavioral intent to call 911 using hypothetical stroke scenarios were conducted at baseline, immediately after the intervention, and 15 months after the initial and only intervention. A composite score was created from 5 traditional stroke symptoms plus a distracter (chest pain). Data were analyzed using SAS version 9.2. A total of 104 students completed both pretests (PTs) and immediate posttests (IPs), and 85 students completed all 3 tests, including a 15-month delayed posttest (DP) (81.7% retention rate). At pretest, 55.8% correctly identified calling 911. The baseline composite score was 3.24 (SD 1.45). At IP, stroke knowledge increased significantly across all items: calling 911 (85.6%, p < 0.001) and composite score (5.30, p < 0.0001). At 15 months, stroke knowledge increased significantly from PT for all measures except sudden headache with a composite score of 4.73 (p < 0.0001, PT vs DP). Three hours of Hip Hop Stroke significantly improved knowledge of stroke symptoms and behavioral intent to call 911 of fifth and sixth grade children living in a high stroke risk neighborhood. This learning persisted for up to 15 months postintervention.

The role of pesticide poisoning in risk of injuries may operate through a link between pesticide-induced depressive symptoms and reduced engagement in safety behaviors. The authors conducted structural equation modeling of cross-sectional data to examine the pattern of associations between pesticide poisoning, depressive symptoms, safety knowledge, safety behaviors, and injury. Interviews of 1637 Colorado farm operators and their spouses from 964 farms were conducted during 1993-1997. Pesticide poisoning was assessed based on a history of ever having been poisoned. The Center for Epidemiologic Studies-Depression scale was used to assess depressive symptoms. Safety knowledge and safety behaviors were assessed using ten items for each latent variable. Outcomes were safety behaviors and injuries. A total of 154 injuries occurred among 1604 individuals with complete data. Pesticide poisoning, financial problems, health, and age predicted negative affect/somatic depressive symptoms with similar effect sizes; sex did not. Depression was more strongly associated with safety behavior than was safety knowledge. Two safety behaviors were significantly associated with an increased risk of injury. This study emphasizes the importance of financial problems and health on depression, and provides further evidence for the link between neurological effects of past pesticide poisoning on risk-taking behaviors and injury.

Background Drinking patterns among Russian women indicate substantial risk for alcohol-exposed pregnancies. Data about women’s knowledge and attitudes related to alcohol consumption during pregnancy and the extent to which women’s knowledge and attitudes affect their alcohol use remain limited. Objectives To describe Russian women’s knowledge and attitudes and assess whether women’s knowledge and attitudes were associated with their risky drinking. Methods Cross-sectional survey. Women of childbearing age (n=648) were recruited at women’s health clinics and asked about their alcohol consumption, pregnancy status, attitudes, and knowledge about effects of alcohol and Fetal Alcohol Syndrome (FAS). Results Women exhibited misconceptions and 40% believed or were uncertain whether alcohol consumption during pregnancy was acceptable. Although 34% had heard of FAS, only 8% possessed accurate knowledge. Knowledge was associated with alcohol consumption among pregnant women, but there was no association between knowledge and risky drinking in non-pregnant women, including those who were at risk for an unplanned pregnancy or were trying to conceive. Attitudes were strongly associated with risky drinking by non-pregnant women across levels of knowledge about FAS and any alcohol use by pregnant women. Conclusions Russian women had limited knowledge and misconceptions about effects of alcohol on fetus, and risky alcohol consumption was strongly associated with women’s attitudes and knowledge. The study provides strong evidence to support continuing public health education about effects of alcohol use during pregnancy. Correcting specific misconceptions and targeting the preconceptional period in health communications are necessary to reduce at-risk drinking and the risk for alcohol-exposed pregnancies.

Bunting, Laura; Boivin, Jacky

2008-08-01

Previous research has highlighted a lack of fertility awareness in the general population especially in relation to the optimal fertile period during the menstrual cycle, incidence of infertility and duration of the reproductive life span. The current study assessed fertility knowledge more broadly in young people and investigated three areas of knowledge, namely risk factors associated with female infertility (e.g. smoking), beliefs in false fertility myths (e.g. benefits of rural living) and beliefs in the illusory benefits of healthy habits (e.g. exercising regularly) on female fertility. The sample (n = 149) consisted of 110 female and 39 male postgraduate and undergraduate university students (average age 24.01, SD = 7.81). Knowledge scores were based on a simple task requiring the participants to estimate the effect a factor would have on a group of 100 women trying to get pregnant. Items (n = 21) were grouped according to three categories: risk factors (e.g. smoking; 7 items), myths (e.g. living in countryside; 7 items) and healthy habits (e.g. being normal weight; 7 items). An analysis of variance showed a significant main effect of factor (P < 0.001) and post hoc tests revealed that young people were significantly better at correctly identifying the effects of risks compared with null effects of healthy habits (P < 0.001) or fertility myths (P < 0.001). Young people are aware that the negative lifestyle factors reduce fertility but falsely believe in fertility myths and the benefits of healthy habits. We suggest that the public education campaigns should be directed to erroneous beliefs about pseudo protective factors.

NASA is developing the knowledge required to accurately predict and to efficiently manage radiation risk in space. The strategy employed has three research components: (1) ground-based simulation of space radiation components to develop a science-based understanding of radiation risk; (2) space-based measurements of the radiation environment on planetary surfaces and interplanetary space, as well as use of space platforms to validate predictions; and, (3) implementation of countermeasures to mitigate risk. NASA intends to significantly expand its support of ground-based radiation research in line with completion of the Booster Applications Facility at Brookhaven National Laboratory, expected in summer of 2003. A joint research solicitation with the Department of Energy is under way and other interagency collaborations are being considered. In addition, a Space Radiation Initiative has been submitted by the Administration to Congress that would provide answers to most questions related to the International Space Station within the next 10 years.

Traditional ecological knowledge and flood risk management: A preliminary case study of the Rwenzori

PubMed Central

2018-01-01

The shift from flood protection to flood risk management, together with recent arguments on incorporating culture in managing risk, underscores the application of traditional ecological knowledge (TEK) in managing disasters from flood hazards. Yet, documentation and incorporation of TEK into practice remains a challenge. This article contributes to addressing this challenge by exploring the existence of TEK to flooding in the Rwenzori Mountains, Uganda. Using semi-structured interviews, data were collected from residents of the Nyamwamba watershed where intense flash floods caused deadly impacts in May 2013. Collected data were analysed using content, thematic and interpretive analysis techniques. Results indicate that TEK is exhibited through various traditional ecological approaches (TEAs). Although endangered, TEAs (conducted through collective action for a communally accepted end) are framed in three main activities: (1) assessment and prediction of rainfall and flood by the traditional hydro-meteorologist (diviner) and the traditional rain forecaster (rainmaker); (2) the mountain cleansing ritual (which act as flood risk awareness platform); and (3) immunising riverine communities through planting certain indigenous plants, which improve hydrological systems through their high conservation value for native ecological diversity. As most TEAs are conducted through collective action, they represent a platform to understand local capacities and enhance adoption of measures, and/or a source of knowledge for new measures to address flood risk. Therefore, full-scale investigations of these TEAs, determining how relevant TEAs are fine-tuned, and (scientific) measures enculturated based on fine-tuned TEAs could result in effective flood risk management in various flood hotspots where TEAs influence action.

Integrating pedagogical content knowledge and pedagogical/psychological knowledge in mathematics

In teacher education at universities, general pedagogical and psychological principles are often treated separately from subject matter knowledge and therefore run the risk of not being applied in the teaching subject. In an experimental study (N = 60 mathematics student teachers) we investigated the effects of providing aspects of general pedagogical/psychological knowledge (PPK) and pedagogical content knowledge (PCK) in an integrated or separated way. In both conditions (“integrated” vs. “separated”), participants individually worked on computer-based learning environments addressing the same topic: use and handling of multiple external representations, a central issue in mathematics. We experimentally varied whether PPK aspects and PCK aspects were treated integrated or apart from one another. As expected, the integrated condition led to greater application of pedagogical/psychological aspects and an increase in applying both knowledge types simultaneously compared to the separated condition. Overall, our findings indicate beneficial effects of an integrated design in teacher education. PMID:25191300

Heart disease is a leading cause of morbidity and mortality in men and women. Our understanding of heart disease stems chiefly from clinical trials on men, but key features of the disease differ in women. This article reports findings from the first Canadian national survey of women that focuses on knowledge, perceptions, and lifestyle related to heart health. A cross-country survey using an adaptation of an instrument used in the United States was undertaken in spring of 2013. Based on online (208) and telephone (1446) responses from a randomly selected sample of women aged 25 or older, a total sample of 1654 weighted percentage estimates were produced. The overall response rate was 12.5%. Just under half of women were able to name smoking as a risk factor of heart disease, and less than one quarter named hypertension or high cholesterol. Fewer than half of women knew the major symptoms of heart disease. Most women prefer to receive information on heart health from their doctor, but only slightly more than half report that their doctor includes discussion of prevention and lifestyle during clinical consultations. Most women lack knowledge of heart disease symptoms and risk factors, and significant proportions are unaware of their own risk status. The findings underscore the opportunity for patient education and intervention regarding risk and prevention of heart disease. Copyright © 2014 Canadian Cardiovascular Society.

This study assessed the public’s health risk awareness of urban air pollution triggered by three megacities in China, and the data are the responses from a sample size of 3868 megacity inhabitants from Shanghai, Nanchang and Wuhan. Descriptive analyses were used to summarize the respondents’ demographics, perceived health risks from air pollution and sources of health-related knowledge on urban air pollution. Chi-square tests were used to examine if participants’ demographics were associated with participant’s general attitudes towards current air quality and the three perceived highest health risks due to urban air pollution. We found low rate of satisfaction of current urban air quality as well as poor knowledge of air pollution related indicator. Participants’ gender, age and travel experience were found to be associated with the satisfaction of current air quality. The knowledge of air pollution related indicator was significantly affected by respondents’ education, monthly income, health status, and sites of study. As many as 46.23% of the participants expressed their feelings of anxiety when exposed to polluted air, especially females, older adults and those with poor health conditions. Most participants believed that coughs/colds, eye problems and skin allergies were the three highest health risks due to urban air pollution based on public education through television/radio, internet and newspaper/magazine. Further public health education is needed to improve public awareness of air pollution and its effects. PMID:27571088

Evaluating driving safety of older adults is an important health topic, but primary care providers (PCP) face multiple barriers in addressing this issue. The study's objectives were to develop an electronic health record (EHR)-based Driving Clinical Support Tool, train PCPs to perform driving assessments utilizing the tool, and systematize documentation of assessment and management of driving safety issues via the tool. The intervention included development of an evidence-based Driving Clinical Support Tool within the EHR, followed by training of internal medicine providers in the tool's content and use. Pre- and postintervention provider surveys and chart review of driving-related patient visits were conducted. Surveys included self-report of preparedness and knowledge to evaluate at-risk older drivers and were analyzed using paired t-test. A chart review of driving-related office visits compared documentation pre- and postintervention including: completeness of appropriate focused history and exam, identification of deficits, patient education, and reporting to appropriate authorities when indicated. Data from 86 providers were analyzed. Pre- and postintervention surveys showed significantly increased self-assessed preparedness (p < .001) and increased driving-related knowledge (p < .001). Postintervention charts showed improved documentation of correct cognitive testing, more referrals/consults, increased patient education about community resources, and appropriate regulatory reporting when deficits were identified. Focused training and an EHR-based clinical support tool improved provider self-reported preparedness and knowledge of how to evaluate at-risk older drivers. The tool improved documentation of driving-related issues and led to improved access to interdisciplinary care coordination.
