Background Bisphosphonate-related osteonecrosis is an infrequent but potentially serious complication. Its treatment remains complex, and in some cases can be mutilating. Prevention, a correct diagnosis and opportune management are crucial. Material and Methods A cross-sectional study was made, interviewing 410 dentists with the aim of assessing their knowledge of the subject. Results Practically all of the dental professionals (99.7%) were found to lack sufficient knowledge of the prevention, diagnosis and management of bisphosphonate-related osteonecrosis. Conclusions Actions including increased diffusion in the professional media and inclusion of the subject in training programs are needed in order to enhance the knowledge of bisphosphonate-related osteonecrosis among dentists and thus prevent complications in this group of patients. Key words:Knowledge, mexico, osteonecrosis, bisphosphonates. PMID:27918741

Background: The incidence of breast and cervical cancers is growing rapidly among Egyptian women. In this context, we assessed the prevalence of, and factors associated with the lack of knowledge among Egyptian females of performing breast self–examination (BSE) and unawareness of cervical smear cancer screening services. Methods: Secondary data analysis was performed on a representative population-based sample of 7,518 Egyptian females aged 15–59 years from the 2015 Egypt Health Issues Survey (EHIS). Crude and adjusted odds ratios (aOR) were used to explore the relationship between sociodemographic variables and having a lack of knowledge of performing BSE or unaware of cervical smear cancer screening service amongst 6,572 and 6,942 Egyptian females aged 21–59 years, respectively. Results: Mean age of females was 36.9 years with 62% aged between 21–39 years. The proportion of women with a lack of knowledge of performing BSE or who were unaware of cervical smear cancer screening service was 87.4% and 92.3%, respectively. After adjusting for potential confounding of sociodemographic and obstetric characteristics, young women aged 21–29 years (P<0.001), primary education or below (P<0.001), residing in rural areas (aOR, 1.37 and 1.48, P=0.001), accessing different media outlets “not at all or less than once a week” (aOR, 2.81 and 1.46, P≤0.05), were associated with a greater likelihood of being with lack knowledge of performing BSE or being unaware of cervical smear cancer screening services. Conclusions: In a country burdened with breast and cervical cancers, the majority of Egyptian women have a lack of knowledge on how to perform BSE or were unaware of the available cervical smear cancer screening services. Robust health campaigns are warranted to raise public knowledge of the method of BSE and of cervical smear cancer screening services, especially amongst females aged less than 30 years, with low levels of education, or those living in rural

Background / aim: Although complementary and alternative medicine (CAM) use is highly prevalent, there is very limited information on dermatologists' attitudes and knowledge about CAM. In this survey, we aimed to study the knowledge and attitude of dermatologists in Saudi Arabia towards CAM. Furthermore, we assessed dermatologists' intention to receive CAM education and training. Methods and design: We collected data through an online cross-sectional survey sent to email addresses of dermatologists in Saudi Arabia. Questions included socio-demographic data, knowledge and attitudes towards CAM practice. Results: A total of 93 questionnaires were returned from dermatologists in various regions of Saudi Arabia. The mean age was 41.7 ± 10.3 (range, 25-63) years. A total of 67% of dermatologists had welcoming attitudes towards CAM. We did not find any significant relationship between age, gender, experience or any other factor and positive attitudes towards CAM. More than 70% of participants reported an interest in learning about CAM. However, only 9 (9.7%) dermatologists had attended CAM courses. Sixty-one participants (65.6%) were eager to receive CAM-specific education, and 66% of dermatologists acknowledged having previously discussed CAM with their patients. The most important reason that dermatologists did not discuss CAM with their patients was a lack of studies supporting CAM (66.7%) and the belief that doctors' knowledge on CAM is insufficient (58.1%). Conclusion: A greater number of dermatologists have an affirmative attitude towards CAM. The willingness to improve knowledge and training indicates that the CAM field could potentially grow in dermatology.

Sarcopenia is an emerging clinical challenge in an ageing population and is associated with serious negative health outcomes. This study aimed to assess the current state of the art regarding the knowledge about the concept of sarcopenia and practice of the diagnostic strategy and management of sarcopenia in a cohort of Dutch healthcare professionals (physicians, physiotherapists, dietitians and others) attending a lecture cycle on sarcopenia. This longitudinal study included Dutch healthcare professionals (n = 223) who were asked to complete a questionnaire before, directly after and five months after (n = 80) attending a lecture cycle on the pathophysiology of sarcopenia, diagnostic strategy and management of sarcopenia, i.e. interventions and collaboration. Before attendance, 69.7% of healthcare professionals stated to know the concept of sarcopenia, 21.4% indicated to know how to diagnose sarcopenia and 82.6% had treated patients with suspected sarcopenia. 47.5% used their clinical view as diagnostic strategy. Handgrip strength was the most frequently used objective diagnostic measure (33.9%). Five months after attendance, reported use of diagnostic tests was increased, i.e. handgrip strength up to 67.4%, gait speed up to 72.1% and muscle mass up to 20.9%. Bottlenecks during implementation of the diagnostic strategy were experienced by 67.1%; lack of awareness among other healthcare professionals, acquisition of equipment and time constraints to perform the diagnostic measures were reported most often. Before attendance, 36.4% stated not to consult a physiotherapists or exercise therapists (PT/ET) or dietitian for sarcopenia interventions, 10.5% consulted a PT/ET, 32.7% a dietitian and 20.5% both a PT/ET and dietitian. Five months after attendance, these percentages were 28.3%, 21.7%, 30.0% and 20.0% respectively. The concept of sarcopenia is familiar to most Dutch healthcare professionals but application in practice is hampered, mostly by lack of knowledge

To identify the self-perceived reasons for unintentional opioid overdose of young heroin users in three Spanish cities and their agreement with objective risk factors for overdose. Computer-Assisted Personal Interviews (CAPI) were held with 991 street-recruited current heroin users aged 18–30. The general reasons for overdose and the reasons for the last overdose suffered were explored with open-ended (OEQs) and pre-coded questions (PCQs). Limited knowledge of overdose risk factors was defined as mention of fewer than two objective risk factors for unintentional overdose in the OEQ. Univariate, bivariate, and logistic regression methods were used. 77.8% (Seville), 64.9% (Madrid) and 57.2% (Barcelona) of participants have limited knowledge of overdose risk factors. Residence in Seville and not having attended courses or meetings on overdoses were significantly associated with limited knowledge, after adjusting for other factors. The most frequently identified general reasons in OEQ or PCQ were using heroin in large amounts (66.8%), together with tranquilizers (62.0%), adulterated (60.7%), or purer than usual (57.6%). Most reasons were selected more frequently in PCQ than in OEQ, especially rapid injection of the entire dose and using heroin shortly after using tranquilizers or alcohol, by injection, or after a period of abstinence. The results were similar for overdoses suffered by participants. Most young heroin users do not have sufficient knowledge of overdose risk factors, especially the use of heroin by injection, after a period of abstinence, or together with alcohol or methadone. Specific informational or educational programs adapted to the local context are critically needed. PMID:16739049

Identification of perceptions about herpes zoster (HZ) disease, vaccine effectiveness and safety, and vaccine recommendations may impact immunization practices of physicians for HIV-infected patients. A survey was used to quantify knowledge of HZ as well as determine physician immunization perceptions and practices. There were 272/1700 respondents (16%). Correct answers for the incidence of varicella zoster virus (VZV) infection in adults and incidence of HZ in HIV-infected patients were recorded by 14% and 10% of providers, respectively. Providers reported poor knowledge of the incidence of disease recurrence in HIV-infected patients (41% correct), potency of HZ vaccine (47.5% correct) and mechanism of protection against reactivation of VZV (66% correct). Most (88%) agreed that HZ was a serious disease, and 73% believed that the burden of disease made vaccination important. A majority (75%) did not vaccinate HIV patients with HZ vaccine regardless of antiretroviral therapy status. Barriers to administration included safety concerns, concern that vaccine would not prevent HZ, risk of HZ dissemination, reimbursement issues and lack of Infectious Diseases Society of America (IDSA) guidelines. Only 38% of providers agreed that CDC guidelines were clear and 50% believed that clinical trials were needed prior to use of HZ vaccine in HIV-infected patients. Education about HZ is needed among HIV providers. Providers perceived vaccination as important, but data on vaccine safety and clear guidance from the CDC on this issue are lacking.

To investigate pregnant women's knowledge of their body mass index (BMI) and their knowledge of gestational weight gain guidelines. Participants were recruited when attending their nuchal translucency scan at between 11 and 13 weeks, 6-days gestation in Dunedin or Christchurch, New Zealand. Recruitment staff measured participants' weight and height. By way of a self-administered, paper-based survey, participants were asked to identify their body size (including: underweight (BMI <18.5 kg/m2); normal weight (18.5-24.9); overweight (25-29.9); and obese (≥30)), and recommended gestational weight gain (including the 2009 Institute of Medicine guidelines for healthy weight gain in pregnancy, along with the options: "I should not gain any weight in my pregnancy", plus "It does not matter how much weight I gain"). Participant-measured BMI was compared to responses for perceived BMI and recommended gestational weight gain to assess accuracy. Demographic predictors of accuracy were also investigated. In total, 644 women were included. Sixty-six percent of these correctly identified their BMI category, however only 31% identified their correct gestational weight gain recommendation. Overweight and obese women were much more likely to underestimate their BMI than normal weight women (p<0.001 for both). Overweight and obese women were also more likely to overestimate their weight gain recommendation (OR=4, p<0.001; OR=18, p<0.001, respectively) while normal weight women were more likely to underestimate their weight gain recommendation (p<0.001). Independent of BMI, women of New Zealand European ethnicity were less likely to underestimate their recommended gestational weight gain compared to other women of non-Māori/non-Pacific Island ethnicity (p=0.001), whereas younger women (p=0.012) were more likely to underestimate recommended gestational weight gain. The present study indicates that New Zealand women, particularly those who are overweight and obese, lack accurate

Rising life expectancy means an increase in the number of elderly people with hearing loss in the population. Many elderly people live in nursing homes, with varying care needs. A substantial proportion of these people will need help with their hearing aids and other hearing devices. The objective of the study has been to assess the knowledge, experience, skills, competence, and need for information of staff at nursing homes in relation to residents' hearing loss and hearing aids. One hundred and ninety-five employees at seven nursing homes participated in the study. The main approach was a descriptive study, using questionnaires. The main findings are that 73% of informants found that many residents need help with their hearing aids. Only one-tenth report that they know enough about the residents' hearing aids. Almost four out of five informants find that the residents become socially isolated as a result of hearing loss. Seventy-eight percent agree to some extent that more residents would benefit from hearing aids. Staff at nursing homes have insufficient knowledge about hearing loss and hearing aids. Increased focus on the elderly with hearing impairment in nursing homes is needed. Contact between nursing homes and audiological specialists should be improved to best followup hearing loss and hearing aids.

The impact of the Papanicolaou (Pap) smear on the prevention of cervical cancer is one of the greatest public health success stories. However, it is not clear if women understand the purpose of the Pap smear despite recent advancements and national attention over cervical cancer prevention. The purpose of this study was to examine Pap smear knowledge among three high-risk populations at different points in time. Women from three separate human papillomavirus (HPV) psychosocial studies completed surveys assessing Pap smear knowledge: (1) HPV-positive women (prevaccine population in 2005-2006, n=154, mean age 23.5), (2) college women (postvaccine population in 2008, n=276, mean age 18.9), and (3) minority college women (postvaccine population in 2011, n=711, mean age 23.3). Frequencies and logistic regression were employed to examine associations between demographic factors and accurate knowledge of Pap smear testing within each study. Approximately one quarter of participants across all three samples did not know that the Pap smear is a test for cervical cancer. Participants also incorrectly believed that the Pap smear tests for HPV (82%-91%), vaginal infections (76%-92%), yeast infections (65%-86%), gonorrhea (55%-81%), herpes (53%-80%), HIV/AIDS (22%-59%), and pregnancy (17%-38%). Among all three studies, older age was the only factor significant with higher Pap knowledge. Higher HPV knowledge scores were significantly associated with higher Pap knowledge in studies 2 and 3 only. Knowledge about the purpose of the Pap smear remains low. Findings underscore the significant need for clear and consistent messages among high-risk women regarding the prevention of cervical cancer and other reproductive health conditions.

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.

The sufficiency of 169 athletes (six disciplines: bullet shooting, biathlon, bobsleigh, skeleton, freestyle skiing, snowboarding) with vitamins A, E, C, B2, and beta-carotene has been investigated in April-September 2013. All athletes (102 juniors, mean age--18.5 +/- 0.3 years, and 67 adult high-performance athletes, mean age--26.8 +/- 0.7 years) were sufficiently supplied with vitamin A (70.7 +/- 1.7 mcg/dl). Mean blood serum retinol level was 15% higher the upper limit of the norm (80 mcg/dl) in biathletes while median reached 90.9 mcg/dl. Blood serum level of tocopherols (1.22 +/- 0.03 mg/dl), ascorbic acid (1.06 +/- 0.03 mg/dl), riboflavin (7.1 +/- 0.4 ng/ml), and beta-carotene (25.1 +/- 1.7 mcg/dl) was in within normal range, but the incidence of insufficiency of vitamins E, C, B2, and carotenoid among athletes varied in the range of 0-25, 0-17, 15-67 and 42-75%, respectively. 95% of adults and 80% of younger athletes were sufficiently provided with vitamin E. Vitamin E level in blood serum of juniors involved in skeleton and biathlon was lower by 51 and 72% (p < 0.05), than this parameter in adult athletes. Vitamin A, C and B2, and beta-carotene blood serum level did not significantly differ in junior and adult athletes. Women were better supplied with vitamins C, B2, and beta-carotene: a reduced blood serum level of these micronutrients in women was detected 2-3 fold rare (p < 0.10) than among men. Blood serum concentration of vitamin C (1.20 +/- 0.05 mg/dl) and beta-carotene (32.0 +/- 3.9 mcg/dl) in women was greater by 15 and 54% (p < 0.05) than in men. In general, the biathletes were better provided with vitamins compared with other athletes. The vast majority (80%) were optimally provided by all three antioxidants (beta-carotene and vitamins E and C). In other sports, the relative quantity of athletes sufficiently supplied with these essential nutrients did not exceed 56%. The quota of supplied with all antioxidants among bullet shooters (31.1%) and

Objective To investigate the use of functional outcome measurements after spinal cord injury (SCI) in current clinical practice and to explore the knowledge about the Spinal Cord Independence Measure (SCIM) among SCI physicians in China, and to find facilitators for a broader utilization of SCIM. Design A survey-based study. Setting SCI workshops at Peking University. Participants 125 Chinese SCI physicians attending annual workshops in two consecutive years. Interventions Not applicable. Outcome measures A questionnaire was administered. The following items were included: whether functional outcome measurement for SCI individuals was performed and with which assessment tool(s); what items should be included in the assessment; whether they knew about the SCIM, its latest version, the Chinese translation, and if so from what source; the possible reasons why SCIM was not implemented in clinical practice; and whether training before using the SCIM was needed, and the training method preferred. Results Among these physicians, 84.8% performed functional outcome measurement for individuals with SCI, but only 29.6% of attendees were aware of the SCIM and 20.8% had used it. Lack of training was the major reason why SCIM was not used in clinical practice. Furthermore, 74.4% of the physicians felt they needed formal training before using the SCIM. Conclusion The use of SCIM is limited in clinical practice in China, which is mainly attributed to lack of knowledge and training. Formal training on the use of the SCIM is essential for its dissemination and will improve functional SCI outcome measurement in China.

In recent years, the value of social learning approaches as part of the design and delivery of formalised coach development initiatives has gained credence in the literature. However, insight is currently lacking into the fundamental social dimensions that underpin coach learning. Accordingly, this study aimed to explore coaches' perceptions of their actual and preferred methods of acquiring new coaching knowledge, the types of knowledge they currently acquire and/or desire, and their application of new knowledge. Responses to an online survey, completed by practicing coaches (N = 320) in a range of sports and contexts, were analysed descriptively and inductively. Results revealed that coaches preferred, and mostly acquired, coaching knowledge from informal learning activities, especially when these permitted social interaction. Notably, however, formal coach education courses were also reported relatively frequently as a source of recent knowledge acquisition. Nevertheless, critical justification for and application of acquired knowledge was largely absent. Based on the findings, we suggest that, before social learning activities such as mentoring schemes and communities of practice are placed at the centre of formalised coach development provision, coach educators must put in place the support structures to better enable coaches to recognise and deal with the potentially mixed influences of the social milieu on coach learning, aiming to ensure that their informal development is sufficiently open-minded, reflective and critical.

Egypt has by far the largest hepatitis C virus (HCV) prevalence in the world with 14.7% of the population being antibody positive for HCV. The aim of this study was to examine the association between knowledge of HCV and HCV antibody positivity among the Egyptian population. We characterized different measures of HCV knowledge and examined their associations with HCV prevalence, by analyzing a nationally representative database using standard epidemiologic methods. The database, the 2008 Egyptian Demographic and Health Survey, included demographic, health, and HCV biomarker information for a sample of over 12,000 individuals. Basic knowledge of HCV was found to be high, but multiple gaps were identified in the specific knowledge of HCV and its modes of transmission. There was no statistically significant difference in HCV prevalence between those who have heard of HCV infection and those who have not (14.4% vs. 15.9%, p>.05). Similar results were found for the other HCV knowledge measures including those specific to HCV modes of transmission and to the sources of information for HCV awareness. Logistic regression analyses did not demonstrate an association between HCV knowledge and HCV prevalence. Our results do not provide support for an effect of awareness on reducing the risk of HCV infection in Egypt. Public health messages directed at the lay public may not provide sufficient empowerment for individuals to avoid HCV infection, and should be complemented with prevention programs to promote and strengthen infection control in the settings of exposure, particularly in health care facilities.

The serious long-term complications of sexually transmitted infections (STI) in women and newborns are well-documented. Particularly, STI imply considerable social consequences for women. Low STI knowledge has been shown to be associated with unsafe sex. In Vietnam, misconceptions regarding STI exist, and rural women delay seeking care for STI. The aim of the study was to investigate knowledge of STI among women aged 15 to 49 years in a rural district of Vietnam and to evaluate possible associations between socioeconomic factors and STI knowledge. A cross-sectional population-based study using face-to-face interviews was carried out between March and May 2006 in a demographic surveillance site in rural Vietnam. In total, 1805 women aged 15-49 years were randomly selected to participate in the study. The interviews were based on a structured questionnaire including questions on sociodemographic characteristics of the women and their knowledge about STI. Each correct answer was scored 1, incorrect or do not know answer was scored 0. Multivariate analyses were applied to examine associations between socio-economic conditions and STI knowledge. Intra-cluster correlation was calculated to examine similarities of STI knowledge within clusters. Of the 1,805 respondents, 78% (73% married vs. 93% unmarried, p < 0.001) did not know any symptoms of STI, 50% could not identify any cause of STI, 59% (54% married vs. 76% unmarried, p < 0.001) did not know that STI can be prevented. Only 31% of the respondents (36% married vs. 14% unmarried, p < 0.001) answered that condom use could protect against STI, and 56% considered partner treatment necessary. Of 40 possible correct answers, the mean knowledge score was 6.5 (range 0-26, median 6). Young, unmarried women and women who lived in the highlands or mountainous areas demonstrated very low levels of STI knowledge (regression coefficients -1.3 and -2.5, respectively, p < 0.001). Experience of an induced abortion was significantly

Sufficient Forecasting Using Factor Models

2017-01-01

We consider forecasting a single time series when there is a large number of predictors and a possible nonlinear effect. The dimensionality was first reduced via a high-dimensional (approximate) factor model implemented by the principal component analysis. Using the extracted factors, we develop a novel forecasting method called the sufficient forecasting, which provides a set of sufficient predictive indices, inferred from high-dimensional predictors, to deliver additional predictive power. The projected principal component analysis will be employed to enhance the accuracy of inferred factors when a semi-parametric (approximate) factor model is assumed. Our method is also applicable to cross-sectional sufficient regression using extracted factors. The connection between the sufficient forecasting and the deep learning architecture is explicitly stated. The sufficient forecasting correctly estimates projection indices of the underlying factors even in the presence of a nonparametric forecasting function. The proposed method extends the sufficient dimension reduction to high-dimensional regimes by condensing the cross-sectional information through factor models. We derive asymptotic properties for the estimate of the central subspace spanned by these projection directions as well as the estimates of the sufficient predictive indices. We further show that the natural method of running multiple regression of target on estimated factors yields a linear estimate that actually falls into this central subspace. Our method and theory allow the number of predictors to be larger than the number of observations. We finally demonstrate that the sufficient forecasting improves upon the linear forecasting in both simulation studies and an empirical study of forecasting macroeconomic variables. PMID:29731537

To assess the extent of undergraduate medical training on alcohol use disorders (AUD) and smoking, and medical students' perceived knowledge regarding consequences of, and treatment options for, these disorders compared with other chronic conditions. Cross-sectional survey assessing teaching and perceived knowledge of health consequences and treatment options for AUD and smoking compared with diabetes and hypertension. Medical schools in Germany. Twenty-five of 36 medical school offices (response rate 69.4%) and 19 526 of 39 358 students from 27 medical schools (response rate 49.6%). Medical schools were asked to provide information on curricular coverage of the four conditions. Students reported their year of study and perceived knowledge about the consequences of all four disorders and perceived knowledge of treatment options. Courses time-tabled approximately half as many teaching hours on AUD and tobacco as on diabetes or hypertension. Final-year students reported high levels of knowledge of consequences of all four conditions and how to treat diabetes and hypertension, but only 20% believed they knew how to treat alcohol use disorders or smoking. Curriculum coverage in German medical schools of alcohol use disorders and smoking is half that of diabetes and hypertension, and in the final year of their undergraduate training most students reported inadequate knowledge of how to intervene to address them. © 2012 The Authors.

SUMMARY Background It is not known whether cardiovascular disease (CVD) risk level is related to knowledge of the leading cause of death of women, or heart attack symptoms. Hypothesis Women with higher CVD risk estimated by Framingham Risk Score (FRS) or Metabolic Syndrome (MS) have lower CVD knowledge. Methods Women visiting primary care clinics completed a standardized behavioral risk questionnaire. Blood pressure, weight, height, waist size, fasting glucose and lipid profile were assessed. Women were queried regarding CVD knowledge. Results Participants (n=823) were Hispanic women (46%), Non-Hispanic White (37%), Non-Hispanic Black (8%). FRS was determined in 278: low (63%), moderate (29%), and high (8%); 24% had ≥3 components of MS. The leading cause of death was answered correctly by 54%, heart attack symptoms by 67%. Knowledge was lowest among racial/ethnic minorities and those with less education (both p<0.001). Increasing FRS was inversely associated with knowing the leading cause of death (low 72%, moderate 68%, high 45%, p=0.045). After multivariable adjustment, moderate/high FRS was inversely associated with knowing symptoms (moderate OR 0.52, 95% CI 0.28–0.98, high OR 0.29, 95% CI 0.11–0.81), but not the leading cause of death. MS was inversely associated with knowing the leading cause of death (p<0.001) or heart attack symptoms (p=0.018), but not after multivariable adjustment. Conclusions Women with higher FRS were less likely to know heart attack symptoms. Efforts to target those at higher CVD risk must persist or the most vulnerable may suffer disproportionately, not only because of risk factors, but also inadequate knowledge. PMID:23338973

Frew, Bethany A.

Features of existing wholesale electricity markets, such as administrative pricing rules and policy-based reliability standards, can distort market incentives from allowing generators sufficient opportunities to recover both fixed and variable costs. Moreover, these challenges can be amplified by other factors, including (1) inelastic demand resulting from a lack of price signal clarity, (2) low- or near-zero marginal cost generation, particularly arising from low natural gas fuel prices and variable generation (VG), such as wind and solar, and (3) the variability and uncertainty of this VG. As power systems begin to incorporate higher shares of VG, many questions arise about themore » suitability of the existing marginal-cost-based price formation, primarily within an energy-only market structure, to ensure the economic viability of resources that might be needed to provide system reliability.

The changes in serum 25-hydroxyvitamin D (25(OH)D) in adolescents from summer to winter and optimal serum vitamin D levels in the summer to ensure adequate vitamin D levels at the end of winter are currently unknown. This study was conducted to address this knowledge gap. The study was conducted as a cohort study. Sixty-eight participants aged 7-18 years and who had sufficient vitamin D levels at the end of the summer in 2011 were selected using stratified random sampling. Subsequently, the participants' vitamin D levels were measured at the end of the winter in 2012. A receiver operating characteristic (ROC) curve was used to determine optimal cutoff points for vitamin D at the end of the summer to predict sufficient vitamin D levels at the end of the winter. The results indicated that 89.7% of all the participants had a decrease in vitamin D levels from summer to winter: 14.7% of them were vitamin D-deficient, 36.8% had insufficient vitamin D concentrations and only 48.5% where able to maintain sufficient vitamin D. The optimal cutoff point to provide assurance of sufficient serum vitamin D at the end of the winter was 40 ng/mL at the end of the summer. Sex, age and vitamin D levels at the end of the summer were significant predictors of non-sufficient vitamin D at the end of the winter. In this age group, a dramatic reduction in vitamin D was observed over the follow-up period. Sufficient vitamin D at the end of the summer did not guarantee vitamin D sufficiency at the end of the winter. We found 40 ng/mL as an optimal cutoff point.

To identify the prevalence of knowledge of the current UK physical activity guidelines which were introduced in 2011 and prior physical activity guidelines (30 min on 5 days each week) within two large samples of UK adult's. To investigate whether knowledge of physical activity guidelines differs according to demographics such as ethnicity, age, education and employment status. Descriptive cross-sectional study comparing two distinctive adult samples. National survey and online-administered survey conducted in England. The 2007 Health Survey for England provides data on knowledge of physical activity guidelines from 2860 UK adults (56% women, 89% white, 63% under 45 years old). In 2013, an online survey was disseminated and data were collected from 1797 UK adults on knowledge of the most recent physical activity guidelines. The 2013 sample was 70% women, 92% white and 57% under 45 years old. All adults in both samples were >18 years old and without illnesses/disorders likely to restrict physical activity. Knowledge of physical activity guidelines in 2007 and 2013. Demographic correlates of knowledge of moderate-to-vigorous physical activity guidelines. 18% of the 2013 sample accurately recalled the current physical activity guidelines compared with 11% of the 2007 sample who accurately recalled the previous guidelines. The differences in knowledge of physical activity guidelines existed for marital status, gender, age, education and employment status within both 2007 and 2013 samples (p<0.05). Men with lower education and employment status (unemployed including student and retired) and older adults were less likely to know physical activity guidelines (p<0.05). Knowledge of physical activity guidelines remained higher in the 2013 sample after controlling for demographic differences (p<0.05). Disadvantaged population groups are less knowledgeable about physical activity guidelines. Although knowledge of physical activity guidelines appears to have increased in

Can New Zealand achieve self-sufficiency in its nursing workforce?

North, Nicola

2011-01-01

This paper reviews impacts on the nursing workforce of health policy and reforms of the past two decades and suggests reasons for both current difficulties in retaining nurses in the workforce and measures to achieve short-term improvements. Difficulties in retaining nurses in the New Zealand workforce have contributed to nursing shortages, leading to a dependence on overseas recruitment. In a context of global shortages and having to compete in a global nursing labour market, an alternative to dependence on overseas nurses is self-sufficiency. Discursive paper. Analysis of nursing workforce data highlighted threats to self-sufficiency, including age structure, high rates of emigration of New Zealand nurses with reliance on overseas nurses and an annual output of nurses that is insufficient to replace both expected retiring nurses and emigrating nurses. A review of recent policy and other documents indicates that two decades of health reform and lack of a strategic focus on nursing has contributed to shortages. Recent strategic approaches to the nursing workforce have included workforce stocktakes, integrated health workforce development and nursing workforce projections, with a single authority now responsible for planning, education, training and development for all health professions and sectors. Current health and nursing workforce development strategies offer wide-ranging and ambitious approaches. An alternative approach is advocated: based on workforce data analysis, pressing threats to self-sufficiency and measures available are identified to achieve, in the short term, the maximum impact on retaining nurses. A human resources in health approach is recommended that focuses on employment conditions and professional nursing as well as recruitment and retention strategies. Nursing is identified as 'crucial' to meeting demands for health care. A shortage of nurses threatens delivery of health services and supports the case for self-sufficiency in the nursing

These results were applied, so that they characterize linear sufficient statistics for families of the exponential type, including as special cases the Wishart and multivariate normal distributions. The latter result was used to establish precisely which procedures for sampling from a normal population had the property that the sample mean was a sufficient statistic.

In Argentina, the difficulty in covering neonatologist's positions represent an increasing problem. The absence of a coordinated and organized health system on one hand, and the lack of adaptation of the neonatologist's role to the current situation of the maternal and child care on the other, prevent the correct assistential coverage. The inadequate work conditions, the professional risks, the wide amount of time devoted to formation and studying, and the lack of knowledge of the professionals necessities and difficulties have a negative impact when it comes to incorporate new specialists. A global approach of the problem is essential to reach enduring answers.

The importance of immunoproteasomes to antigen presentation has been unclear because animals totally lacking immunoproteasomes have not been previously developed. Here we show that dendritic cells from mice lacking the three immunoproteasome catalytic subunits display defects in presenting multiple major histocompatability (MHC) class I epitopes. During viral infection in vivo, the presentation of a majority of MHC class I epitopes is markedly reduced in immunoproteasome-deficient animals, while presentation of MHC class II peptides is unaffected. By mass spectrometry the repertoire of MHC class I-presented peptides is ~50% different and these differences are sufficient to stimulate robust transplant rejection of wild type cells in mutant mice. These results indicate that immunoproteasomes play a much more important role in antigen presentation than previously thought. PMID:22197977

Enabling women with inflammatory bowel diseases (IBD) to have successful pregnancies requires complex decisions. The study aimed to assess patients' views on IBD and pregnancy and to evaluate any association with subject knowledge. General attitudes of females with IBD were assessed on fertility, medication use, delivery mode and pregnancy outcomes. Attitudes regarding personal situation were assessed in participants nulliparous since IBD diagnosis. Knowledge of pregnancy-related issues in IBD was assessed by the Crohn's and Colitis Pregnancy Knowledge Score 'CCPKnow'. Of 145 participants 68% of participants agreed with need for medical therapy for flares during pregnancy, but 24% felt it more important to tolerate symptoms. 36% believed that all IBD medication is harmful to unborn children. Of 96 women nulliparous after IBD diagnosis, 46% were worried about infertility, 75% expressed concern about passing IBD to offspring and 30% considered not having children. Nearly all participants worried about the effects of IBD on pregnancy and the effects of pregnancy on IBD. General attitudes that 'medication should be stopped prior to conception' (P<0.001), 'pregnant women should avoid all IBD drugs' (P<0.001), and 'put up with symptoms' (P<0.001) were associated with significantly lower CCPKnow scores. Over a third of patients considered IBD medication harmful to unborn children. Fear of infertility and concerns about inheritance may explain high rates of voluntary childlessness. Attitudes contrary to medical evidence were associated with significantly lower knowledge. Young women with IBD, particularly those with poor knowledge, should be offered education and counselling about pregnancy-related issues. Copyright © 2012 European Crohn's and Colitis Organisation.

Confidence in the Knowledge Base of English Language Learners Studying Science: Using Agency to Compensate for the Lack of Adequate Linguistic Identity

NASA Astrophysics Data System (ADS)

Hayes, Aneta L.; Mansour, Nasser

2017-04-01

Changes in the cultural and linguistic environments of learners are often associated with identity shifts. The aim of this study was to explore what identity shifts occur when science students from Bahraini national schools transition to an international university. The role of two aspects of learner identity—that is, English proficiency and science background knowledge, was examined in this study. Focus groups and semi-structured interviews were conducted with students and with university lecturers. The analysis suggested three conceptual themes of (1) reliance on science knowledge, (2) the auxiliary role of professional language and (3) adequacy of student learning strategies, demonstrating what subjective meanings the participants ascribe to the interplay between science knowledge and linguistic ability. The findings suggest that despite the lack of adequate linguistic attributes, the students are still able to successfully learn science in the context of language change. It is also implied that through strategically utilising their academic background in science, students preserve their identity as successful learners from school through to university. We conclude that agency plays a separate role in transition and is not a sole function of identity. We also contest the idea of language as a necessary attribute of one's identity as it was perceived by our participants to be an advantage and an auxiliary tool rather than a requirement.

In this study, a knowledge audit was conducted based on organizational intelligence quotient (OIQ) principles of Iran's Ministry of Health and Medical Education (MOHME) to determine levers that can enhance OIQ in healthcare. The mixed method study was conducted within the MOHME. The study population consisted of 15 senior managers and policymakers. A tool based on literature review and panel expert opinions was developed to perform a knowledge audit. The significant results of this auditing revealed the following: lack of defined standard processes for organizing knowledge management (KM), lack of a knowledge map, absence of a trustee to implement KM, absence of specialists to produce a knowledge map, individuals' unwillingness to share knowledge, implicitness of knowledge format, occasional nature of knowledge documentation for repeated use, lack of a mechanism to determine repetitive tasks, lack of a reward system for the formation of communities, groups and networks, non-updatedness of the available knowledge, and absence of commercial knowledge. The analysis of the audit findings revealed that three levers for enhancing OIQ, including structure and process, organizational culture, and information technology must be created or modified.

As with most mental health disorders, the topic of hazing is not exclusive to the student athlete. However, it is also clear that the unique set of situations faced by athletes create a set of additional and difficult challenges to their mental and physical well-being. A deep-rooted culture, a lack of knowledge about hazing and its causal relationships, and a failure to act by teammates and adults all play a role in the propagation of this danger. Also, in an era where the popular press similarly celebrates and chastises episodes of hazing, it is increasingly crucial to turn to the scientific literature for guidance. To provide a comprehensive review of the scientific research on hazing in sports and to make recommendations for enhancing the approach and assistance to those in need on an individual and societal level. Qualitative literature review of hazing in collegiate and school sports. Databases including PubMed, Google Scholar, SPORTDiscus, EMBASE and MEDLINE were searched using standardised terms, alone and in combination, including 'hazing', 'bullying', 'sport', 'athlete', 'college', 'school' and 'youth'. Despite increased attention to its dangers, hazing remains pervasive throughout the sports world. However, many do not recognise those actions as consistent with hazing. A change in culture, increased education and awareness, along with methodologically sound strategies for action must occur in order to reduce the ill effects and cycle of hazing. To date, current information and efforts are lacking. Published by the BMJ Publishing Group Limited.

To assess knowledge, attitudes, and practices on evidence-based medicine (EBM) among doctors in selected hospitals in Sri Lanka. A cross-sectional descriptive study was conducted among 315 doctors in five government hospitals in Sri Lanka between December 2007 and January 2008. A pre-tested self-administered questionnaire was used to gather information on knowledge, attitudes, and practices. Of the 407 invited, 315 doctors participated, among whom, 87% (271) had heard the term EBM, 30% (n= 94) were aware of the Cochrane Library, and 8.5% (n= 27) were current users of it. Forty-seven per cent (n= 148) claimed to understand the terms systematic review and 37% (n= 115) meta-analysis. Twenty-four per cent (n= 77) had been exposed to some form of EBM training. All three components of EBM were known by 18% (n= 56) of participants. Attitudes toward EBM were positive among 76% (n= 239), 80% (n= 251) believed the practice of EBM would lead to improved patient care, and 77% (n= 243) considered EBM to be fundamental to professional practice. Just 3% (n= 13) considered it unimportant. EBM was used in clinical practice by 54% (n= 169) of participants. Thirty-six per cent (n= 114) referred to EBM sources when relevant. Available clinical guidelines were referred to by 56% (n= 176), and 34% (n= 107) thought that available guidelines provide sufficient support for the practice of EBM. The main barriers to practicing EBM were insufficient resources, overwork, lack of exposure to EBM, and lack of time and lack of endorsement of the need to practice EBM. Knowledge and practices of EBM among Sri Lanka doctors were poor. However, attitudes toward EBM were relatively good. © 2010 Blackwell Publishing Asia Pty Ltd and Chinese Cochrane Center, West China Hospital of Sichuan University.

Sonic hedgehog in the notochord is sufficient for patterning of the intervertebral discs

PubMed Central

Choi, Kyung-Suk; Lee, Chanmi; Harfe, Brian D.

2012-01-01

The intervertebral discs, located between adjacent vertebrae, are required for stability of the spine and distributing mechanical load throughout the vertebral column. All cell types located in thes middle regions of the discs, called nuclei pulposi, are derived from the embryonic notochord. Recently, it was shown that the hedgehog signaling pathway plays an essential role during formation of nuclei pulposi. However, during the time that nuclei pulposi are forming, Shh is expressed in both the notochord and the nearby floor plate. To determine the source of SHH protein sufficient for formation of nuclei pulposi we removed Shh from either the floor plate or the notochord using tamoxifen-inducible Cre alleles. Removal of Shh from the floor plate resulted in phenotypically normal intervertebral discs, indicating that Shh expression in this tissue is not required for disc patterning. In addition, embryos that lacked Shh in the floor plate had normal vertebral columns, demonstrating that Shh expression in the notochord is sufficient for pattering the entire vertebral column. Removal of Shh from the notochord resulted in the absence of Shh in the floor plate, loss of intervertebral discs and vertebral structures. These data indicate that Shh expression in the notochord is sufficient for patterning of the intervertebral discs and the vertebral column. PMID:22841806

Design of the software architecture for a knowledge driven HIS is presented. In our design the frame has been used as the basic unit of knowledge representation. The structure of the frame is being designed to be sufficiently universal to contain knowledge required to implement not only expert systems, but almost all traditional HIS functions including ADT, order entry and results review. The design incorporates a two level format for the knowledge. The first level as ASCII records is used to maintain the knowledge base while the second level converted by special knowledge compilers to standard computer languages is used for efficient implementation of the knowledge applications.

Resource Utilization and Site Selection for a Self-Sufficient Martian Outpost

1998-01-01

As a planet with striking similarities to Earth, Mars is an important focus for scientific research aimed at understanding the processes of planetary evolution and the formation of our solar system. Fortunately, Mars is also a planet with abundant natural resources, including assessible materials that can be used to support human life and to sustain a self-sufficient martian outpost. Resources required include water, breathable air, food, shelter, energy, and fuel. Through a mission design based on in situ resource development, we can establish a permanent outpost on Mars beginning with the first manned mission. This paper examines the potential for supporting the first manned mission with the objective of achieving self-sufficiency through well-understood resource development and a program of rigorous scientific research aimed at extending that capability. We examine the potential for initially extracting critical resources from the martian environment, and discuss the scientific investigations required to identify additional resources in the atmosphere, on the surface, and within the subsurface. We also discuss our current state of knowledge of Mars, technical considerations of resource utilization, and using unmanned missions' data for selecting an optimal site. The primary goal of achieving self-sufficiency on Mars would accelerate the development of human colonization beyond Earth, while providing a robust and permanent martian base from which humans can explore and conduct long-term research on planetary evolution, the solar system, and life itself.

Vaccine vial monitor (VVM) is now commonly used for vaccines that are included in the National Immunization Schedule in India. It helps to indicate the viability of the vaccine and of the proper functioning of the cold chain. This is useful as it prevents health personnel from administering damaged vaccine. Studies have shown a lack of awareness of health workers regarding the use and interpretation of a VVM. The current study, undertaken among the caregivers of children who were immunized, showed that this lack of information about the VVM also exists among the caregivers. This deficiency in knowledge, both in the health workers and the caregivers, can affect the health of the child and needs urgent attention.

Towards Knowledge Management for Smart Manufacturing.

Feng, Shaw C; Bernstein, William Z; Hedberg, Thomas; Feeney, Allison Barnard

2017-09-01

The need for capturing knowledge in the digital form in design, process planning, production, and inspection has increasingly become an issue in manufacturing industries as the variety and complexity of product lifecycle applications increase. Both knowledge and data need to be well managed for quality assurance, lifecycle-impact assessment, and design improvement. Some technical barriers exist today that inhibit industry from fully utilizing design, planning, processing, and inspection knowledge. The primary barrier is a lack of a well-accepted mechanism that enables users to integrate data and knowledge. This paper prescribes knowledge management to address a lack of mechanisms for integrating, sharing, and updating domain-specific knowledge in smart manufacturing. Aspects of the knowledge constructs include conceptual design, detailed design, process planning, material property, production, and inspection. The main contribution of this paper is to provide a methodology on what knowledge manufacturing organizations access, update, and archive in the context of smart manufacturing. The case study in this paper provides some example knowledge objects to enable smart manufacturing.

The intervertebral discs, located between adjacent vertebrae, are required for stability of the spine and distributing mechanical load throughout the vertebral column. All cell types located in the middle regions of the discs, called nuclei pulposi, are derived from the embryonic notochord. Recently, it was shown that the hedgehog signaling pathway plays an essential role during formation of nuclei pulposi. However, during the time that nuclei pulposi are forming, Shh is expressed in both the notochord and the nearby floor plate. To determine the source of SHH protein sufficient for formation of nuclei pulposi we removed Shh from either the floor plate or the notochord using tamoxifen-inducible Cre alleles. Removal of Shh from the floor plate resulted in phenotypically normal intervertebral discs, indicating that Shh expression in this tissue is not required for disc patterning. In addition, embryos that lacked Shh in the floor plate had normal vertebral columns, demonstrating that Shh expression in the notochord is sufficient for pattering the entire vertebral column. Removal of Shh from the notochord resulted in the absence of Shh in the floor plate, loss of intervertebral discs and vertebral structures. These data indicate that Shh expression in the notochord is sufficient for patterning of the intervertebral discs and the vertebral column. Copyright © 2012 Elsevier Ireland Ltd.

Reasoning about procedural knowledge

NASA Technical Reports Server (NTRS)

Georgeff, M. P.

1985-01-01

A crucial aspect of automated reasoning about space operations is that knowledge of the problem domain is often procedural in nature - that is, the knowledge is often in the form of sequences of actions or procedures for achieving given goals or reacting to certain situations. In this paper a system is described that explicitly represents and reasons about procedural knowledge. The knowledge representation used is sufficiently rich to describe the effects of arbitrary sequences of tests and actions, and the inference mechanism provides a means for directly using this knowledge to reach desired operational goals. Furthermore, the representation has a declarative semantics that provides for incremental changes to the system, rich explanatory capabilities, and verifiability. The approach also provides a mechanism for reasoning about the use of this knowledge, thus enabling the system to choose effectively between alternative courses of action.

2003-10-01

This cross-sectional study was performed to examine knowledge and attitudes among pharmacists about emergency contraception (EC) and determine the factors associated with their provision of EC. A random systematic sampling method was used to obtain a sample (N = 320) of pharmacies in Pennsylvania. A "mystery shopper" telephone survey method was utilized. Only 35% of pharmacists stated that they would be able to fill a prescription for EC that day. Also, many community pharmacists do not have sufficient or accurate information about EC. In a logistic regression model, pharmacists' lack of information relates to the low proportion of pharmacists able to dispense it. In conclusion, access to EC from community pharmacists in Pennsylvania is severely limited. Interventions to improve timely access to EC involve increased education for pharmacists, as well as increased community request for these products as an incentive for pharmacists to stock them.

Excessive prehospital delay between acute stroke onset and hospital arrival is an ongoing problem. Translating knowledge of stroke warning signs into appropriate action is critical to decrease prehospital delay. Our objectives were to estimate the proportion of Michigan adults who would react appropriately by calling 911 when presented with hypothetical stroke-related scenarios and to examine the association between knowledge of warning signs and calling 911. In 2004, questions regarding initial response to health-related scenarios were added to the Michigan Behavioral Risk Factor Survey, a population-based telephone survey of adults. We calculated the proportion of respondents who would call 911 in response to 3 stroke-related scenarios and examined the association between stroke warning sign knowledge and 911 activation. Among 4841 adults, 27.6% (95% CI, 26.2 to 29.0) had adequate knowledge of stroke warning signs (defined as reporting 3 correct warning signs), and 14.0% (95% CI, 12.9 to 15.1) reported they would call 911 for all 3 stroke-related scenarios. Knowledge of specific stroke warning signs was only modestly associated with calling 911 in response to medical scenarios that involved the same stroke symptom (OR, 1.17 to 1.39). Even among those with adequate knowledge of stroke warning signs, only 17.6% (95% CI, 15.5 to 20.0) would call 911 for all 3 stroke scenarios. In this population-based survey, stroke symptom knowledge was not associated with the intent to call 911 for stroke. This study emphasizes the critical role of motivation in addition to symptom knowledge to reducing delay time to hospital arrival for stroke.

Accessible medical equipment for patients with disabilities in primary care clinics: why is it lacking?

PubMed

Pharr, Jennifer

2013-04-01

Previous research has identified inaccessible medical equipment as a barrier to health care services encountered by people with disabilities. However, no research has been conducted to understand why medical practices lack accessible equipment. The purpose of this study was to examine practice administrators' knowledge of accessible medical equipment and cost of accessible medical equipment to understand why medical practices lack such equipment. Hypotheses were: 1) Practice administrators lacked knowledge about accessible medical equipment and 2) The cost of accessible medical equipment was too great compared to standard equipment for the clinic. This study was a mixed methods survey of primary care practice administrators. The sixty-three participates were members of a medical management organization. Data were collected between December 20, 2011 and January 17, 2012. Proportions, Guttman scalogram, and Spearman's Rho correlation analyses were utilized. For this sample, less than half of the administrators knew that accessible equipment existed and a fourth knew what accessible equipment existed. There was a significant (p < 0.01), positive correlation between knowledge of accessible equipment and pieces of accessible equipment in the clinics. Because less than half of the administrators had ever considered purchasing accessible equipment, it was inconclusive if cost of accessible equipment was too great. Practice administrators' lack of knowledge of accessible medical equipment emphasizes the need not only for more education about the availability of accessible equipment but also about the importance of accessible equipment for their patients with disabilities and for physicians who provide them care.

2012-01-01

There is a growing need for patient education and an evaluation of its outcomes. The aim of this study was to compare ambulatory orthopaedic surgery patients' knowledge with Internet-based education and face-to-face education with a nurse. The following hypothesis was proposed: Internet-based patient education (experiment) is as effective as face-to-face education with a nurse (control) in increasing patients' level of knowledge and sufficiency of knowledge. In addition, the correlations of demographic variables were tested. The patients were randomized to either an experiment group (n = 72) or a control group (n = 75). Empirical data were collected with two instruments. Patients in both groups showed improvement in their knowledge during their care. Patients in the experiment group improved their knowledge level significantly more in total than those patients in the control group. There were no differences in patients' sufficiency of knowledge between the groups. Knowledge was correlated especially with patients' age, gender and earlier ambulatory surgeries. As a conclusion, positive results concerning patients' knowledge could be achieved with the Internet-based education. The Internet is a viable method in ambulatory care.

Introduction Diabetes self-management education is a cornerstone of diabetes care. However, many diabetics in the United Arab Emirates (UAE) lack sufficient knowledge about their disease due to illiteracy. Thus, before considering any possible intervention it was imperative to assess present knowledge, attitudes, and practices of patients towards the management of diabetes. Methods A random sample of 575 DM patients was selected from diabetes outpatient's clinics of Tawam and Al-Ain hospitals in Al-Ain city (UAE) during 2006–2007, and their knowledge attitude and practice assessed using a questionnaire modified from the Michigan Diabetes Research Training Center instrument. Results Thirty-one percent of patients had poor knowledge of diabetes. Seventy-two had negative attitudes towards having the disease and 57% had HbA1c levels reflecting poor glycemic control. Only seventeen percent reported having adequate blood sugar control, while 10% admitted non-compliance with their medications. Knowledge, practice and attitude scores were all statistically significantly positively, but rather weakly, associated, but none of these scores was significantly correlated with HbA1c. Conclusions The study showed low levels of diabetes awareness but positive attitudes towards the importance of DM care and satisfactory diabetes practices in the UAE. Programs to increase patients' awareness about DM are essential for all diabetics in the UAE in order to improve their understanding, compliance and management and, thereby, their ability to cope with the disease.

The present study aimed to evaluate the knowledge and practices of public-sector primary-care health professionals and final-year students regarding the role of nutrition, physical activity and smoking cessation (lifestyle modification) in the management of chronic diseases of lifestyle within the public health-care sector. A comparative cross-sectional descriptive quantitative study was conducted in thirty primary health-care facilities and four tertiary institutions offering medical and/or nursing programmes in Cape Town in the Western Cape Metropole. Stratified random sampling, based on geographical location, was used to select the health facilities while convenience sampling was used to select students at the tertiary institutions. A validated self-administered knowledge test was used to obtain data from the health professionals. Differential lifestyle modification knowledge exists among both health professionals and students, with less than 10 % achieving the desired scores of 80 % or higher. The majority of health professionals seem to be promoting the theoretical concepts of lifestyle modification but experience difficulty in providing practical advice to patients. Of the health professionals evaluated, doctors appeared to have the best knowledge of lifestyle modification. Lack of time, lack of patient adherence and language barriers were given as the main barriers to providing lifestyle counselling. The undergraduate curricula of medical and nursing students should include sufficient training on lifestyle modification, particularly practical advice on diet, physical activity and smoking cessation. Health professionals working at primary health-care facilities should be updated by providing lifestyle modification education as part of continuing medical education.

There is hearsay that prevalence of hydatid disease in Khammam and Nalgonda districts of Andhra Pradesh is high. We report here a preliminary study conducted to determine the magnitude of the problem of hydatid disease and the morbidity associated with it in patients attending MGH, KMM, A.P. (rural hospital). Eleven cases were identified during the period from November 2005 to May 2006 (seven months). Pain in abdomen, mass per abdomen, loss of appetite, pregnancy complicated by cystic echinococcosis (CE), and jaundice were the main clinical symptoms and signs. Ultrasonography, detection and removal of the cysts on the operation table, microscopic examination of the aspirated hydatid fluid were confirmatory. Ziehl-Neelsen stain of the aspirated fluid revealed acid-fast scolices. Interrogation of the patients and their family members (50) revealed that there was a total lack of knowledge of dog-tapeworm-caused infection in humans. They knew 'rabies' as the only disease man gets from dogs, and tapeworms are from pork and beef.

Clinical signs of malnutrition, starvation, cachexia and sarcopenia overlap, as they all imply muscle wasting to a various extent. However, the underlying mechanisms differ fundamentally and therefore distinction between these phenomena has therapeutic and prognostic implications. We aimed to determine whether dietitians in selected European countries have 'sufficient knowledge' regarding malnutrition, starvation, cachexia and sarcopenia, and use these terms in their daily clinical work. An anonymous online survey was performed among dietitians in Belgium, the Netherlands, Norway and Sweden. 'Sufficient knowledge' was defined as having mentioned at least two of the three common domains of malnutrition according to ESPEN definition of malnutrition (2011): 'nutritional balance', 'body composition' and 'functionality and clinical outcome', and a correct answer to three cases on starvation, cachexia and sarcopenia. Chi-square test was used to analyse differences in experience, work place and number of malnourished patients treated between dietitians with 'sufficient knowledge' vs. 'less sufficient knowledge'. 712/7186 responded to the questionnaire, of which data of 369 dietitians were included in the analysis (5%). The term 'malnutrition' is being used in clinical practice by 88% of the respondents. Starvation, cachexia and sarcopenia is being used by 3%, 30% and 12% respectively. The cases on starvation, cachexia and sarcopenia were correctly identified by 58%, 43% and 74% respectively. 13% of the respondents had 'sufficient knowledge'. 31% of the respondents identified all cases correctly. The proportion of respondents with 'sufficient knowledge' was significantly higher in those working in a hospital or in municipality (16%, P < 0.041), as compared to those working in other settings (7%). The results of our survey among dietitians in four European countries show that the percentage of dietitians with 'sufficient knowledge' regarding malnutrition, starvation

To determine the knowledge and attitudes of nurses in Primary Care as regards gender violence and their relationship with socio-demographic factors and cases detected. Cross-sectional, descriptive study. Urban health centres. A total of 167 nurses working in Primary Care. A questionnaire was used that included questions related to knowledge, knowledge perception and attitudes to gender violence attitudes. Variables such as age, gender, marital status, work place and health area were also analysed. The response rate was 114 (68.26%). The percentage of correct responses in the knowledge questions was 62.2%, with a medium level of knowledge being observed. Married nurses or couples living in a stable relationship obtained a higher score (95.2%, P=.077). The low detection (29%) is associated with marital status (P=.004), low knowledge (P=0,008), low knowledge perception (P=.001), lack of training (P=.03) and non-implementation of the gender violence protocol (P=.001). Nurses with low self-perception of their knowledge implement the protocol less often (OR=0.26; 95% CI: 0.1-0.7), and they consider that the lack of training is the main problem in determining the diagnosis (OR=11.24; 95% CI: 1.5-81.1). The level of knowledge was adequate. Nurses have a lack of confidence in terms of their knowledge about gender violence. The detection and diagnosis attitudes are more related to self-perception of levels of knowledge than their real knowledge. Marital status influences the level of knowledge. Professionals state that the lack of training is the main problem to give an efficient healthcare response. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

Bridging the knowledge-resuscitation gap for children: Still a long way to go

PubMed Central

Goldman, Ran D; Ho, Kendall; Peterson, Robert; Kissoon, Niranjan

2007-01-01

The American Heart Association, along with the International Liaison Committee on Resuscitation, recently made changes to the paediatric resuscitation guidelines. Knowledge translation (KT) is imperative, but there is a lack of sufficient evidence for appropriate methodologies for implementation of these guidelines. Paediatric resuscitation presents many challenges; cases happen infrequently, affording few opportunities for implementation of the new guidelines, and are highly stressful and filled with uncertainty. Some KT strategies have shown some success in causing a notable degree of change in behaviour, but none have shown a striking difference when used alone. Previous efforts to disseminate current guidelines centred on development of courses for health care providers and preparing paediatric residents and paediatricians for circumstances they could encounter with paediatric acute illness. None of the studies assessing these techniques measured direct patient outcomes, and only a few demonstrated some long-term knowledge acquisition among trainees. The purpose of the present review was to illuminate the challenges, offer future directions for KT and outline potentially more effective methodologies and strategies to overcome current barriers.

Improvement of chronic disease management in primary care entails monitoring indicators of quality over time and across patients and practices. Informatics tools are needed, yet implementing them remains challenging. To identify critical success factors enabling the translation of clinical and operational knowledge about effective and efficient chronic care management into primary care practice. A prospective case study of positive deviants using key informant interviews, process observation, and document review. A chronic disease management (CDM) collaborative of primary care physicians with documented improvement in adherence to clinical practice guidelines using a web-based patient registry system with CDM guideline-based flow sheet. Thirty community-based physician participants using predominantly paper records, plus a project management team including the physician lead, project manager, evaluator and support team. A critical success factor (CSF) analysis of necessary and sufficient pathways to the translation of knowledge into clinical practice. A web-based CDM 'toolkit' was found to be a direct CSF that allowed this group of physicians to improve their practice by tracking patient care processes using evidence-based clinical practice guideline-based flow sheets. Moreover, the information and communication technology 'factor' was sufficient for success only as part of a set of seven direct CSF components including: health delivery system enhancements, organizational partnerships, funding mechanisms, project management, practice models, and formal knowledge translation practices. Indirect factors that orchestrated success through the direct factor components were also identified. A central insight of this analysis is that a comprehensive quality improvement model was the CSF that drew this set of factors into a functional framework for successful knowledge translation. In complex primary care settings environment where physicians have low adoption rates of

Self-sufficiency, free trade and safety.

PubMed

Rautonen, Jukka

2010-01-01

The relationship between free trade, self-sufficiency and safety of blood and blood components has been a perennial discussion topic in the blood service community. Traditionally, national self-sufficiency has been perceived as the ultimate goal that would also maximize safety. However, very few countries are, or can be, truly self-sufficient when self-sufficiency is understood correctly to encompass the whole value chain from the blood donor to the finished product. This is most striking when plasma derived medicines are considered. Free trade of blood products, or competition, as such can have a negative or positive effect on blood safety. Further, free trade of equipment and reagents and several plasma medicines is actually necessary to meet the domestic demand for blood and blood derivatives in most countries. Opposing free trade due to dogmatic reasons is not in the best interest of any country and will be especially harmful for the developing world. Competition between blood services in the USA has been present for decades. The more than threefold differences in blood product prices between European blood services indicate that competition is long overdue in Europe, too. This competition should be welcomed but carefully and proactively regulated to avoid putting safe and secure blood supply at risk. Copyright 2009 The International Association for Biologicals.

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

2018-05-01

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.

When is Testing Sufficient

Rosenberg, Linda H.; Arthur, James D.; Stapko, Ruth K.; Davani, Darush

1999-01-01

The Software Assurance Technology Center (SATC) at NASA Goddard Space Flight Center has been investigating how projects can determine when sufficient testing has been completed. For most projects, schedules are underestimated, and the last phase of the software development, testing, must be decreased. Two questions are frequently asked: "To what extent is the software error-free? " and "How much time and effort is required to detect and remove the remaining errors? " Clearly, neither question can be answered with absolute certainty. Nonetheless, the ability to answer these questions with some acceptable level of confidence is highly desirable. First, knowing the extent to which a product is error-free, we can judge when it is time to terminate testing. Secondly, if errors are judged to be present, we can perform a cost/benefit trade-off analysis to estimate when the software will be ready for use and at what cost. This paper explains the efforts of the SATC to help projects determine what is sufficient testing and when is the most cost-effective time to stop testing.

2012-01-01

Background We propose a new quantitative measure that enables the researcher to make decisions and test hypotheses about the distribution of knowledge in a community and estimate the richness and sharing of information among informants. In our study, this measure has two levels of analysis: intracultural and intrafamily. Methods Using data collected in northeastern Brazil, we evaluated how these new estimators of richness and sharing behave for different categories of use. Results We observed trends in the distribution of the characteristics of informants. We were also able to evaluate how outliers interfere with these analyses and how other analyses may be conducted using these indices, such as determining the distance between the knowledge of a community and that of experts, as well as exhibiting the importance of these individuals' communal information of biological resources. One of the primary applications of these indices is to supply the researcher with an objective tool to evaluate the scope and behavior of the collected data. PMID:22420565

[Pitfalls in 'orthodox knowledge'].

PubMed

Taneda, Hiroyuki

2003-03-01

Within contemporary society both 'pseudoscience' and 'pseudomedicine' can be found. Such knowledge is seen as incorrect, wrong or irrational. I call them 'unorthodox (uncertain) knowledge'. Conversely, 'orthodox knowledge'--for example, science, medicine, etc.--is seen as correct, right or rational. Some people believe 'unorthodox (uncertain) knowledge'. Experts castigate such people from the standpoint that they lack the basic understanding of 'orthodox knowledge'. That is, experts see the ordinary lay person as subjective, ignorant or irrational (whereas they see themselves as objective, analytical, prudent or rational). But are people ignorant or irrational? The aim of this paper is to examine this question in terms of analyzing the interplay among the characteristics of 'orthodox knowledge', 'unorthodox (uncertain) knowledge' and the nature of people's concerns. Thus, this paper explains that people develop certain situated understandings of 'orthodox knowledge' and/or 'unorthodox (uncertain) knowledge' through their intensive experiences. Also, this paper suggests that people need to rethink or reflect on the good institutions which mediate between people and experts.

The objective of this study was to determine whether noon conference attendance by diagnostic radiology residents is predictive of measurable performance. This single-center retrospective Health Insurance and Portability and Accountability Act (HIPAA)-compliant cross-sectional study was considered "not regulated" by the institutional review board. All diagnostic radiology residents who began residency training from 2008 to 2012 were included (N = 54). Metrics of clinical performance and knowledge were collected, including junior and senior precall test results, American Board of Radiology scores (z-score transformed), American College of Radiology in-training scores (years 1-3), on-call "great call" and minor and major discrepancy rates, on-call and daytime case volumes, and training rotation scores. Multivariate regression models were constructed to determine if conference attendance, match rank order, or starting year could predict these outcomes. Pearson bivariate correlations were calculated. Senior precall test results were moderately correlated with American Board of Radiology (r = 0.41) and American College of Radiology (r = 0.38-0.48) test results and mean rotation scores (r = 0.41), indicating moderate internal validity. However, conference attendance, match rank order, and year of training did not correlate with (r = -0.16-0.16) or predict (P > .05) measurable resident knowledge. On multivariate analysis, neither match rank order (P = .14-.96) nor conference attendance (P = .10-.88) predicted measurable clinical efficiency or accuracy. Year started training predicted greater cross-sectional case volume (P < .0001, β = 0.361-0.516) and less faculty-to-resident feedback (P < 0.0001, β = [-0.628]-[-0.733]). Residents with lower conference attendance are indistinguishable from those who attend more frequently in a wide range of clinical and knowledge-based performance assessments, suggesting that required

Knowledge of badger distribution is important for the management of bovine tuberculosis. At the farm level, typically the only information on badger activity available is from the farmers themselves. This study compares how well farmer perceptions of badger activity match data obtained from ecological surveys. Farmer estimates of numbers of badger setts (burrows) surrounding their farms were generally correlated with field survey results, but tended to be underestimates. Farmers correctly recorded 50 per cent of setts recorded in surveys, with larger setts and active setts more likely to be correctly recorded. Badger visits to farm buildings and yards were also monitored using surveillance cameras. The majority of farmers were aware of badger visits to their farm buildings, but in 22 per cent of cases farmers were not aware of badger visits. At the farm level, knowledge of badger activity will be useful in informing vets and animal health professionals of the potential risks of disease transmission, and hence directing management interventions. However, the tendency to underestimate activity, combined with a lack of detailed knowledge of sett locations, means that farmer estimates of badger activity should be interpreted with caution and in isolation may not be sufficient to inform management interventions.

On the different "worlds" of intra-organizational knowledge management: Understanding idiosyncratic variation in MNC cross-site knowledge-sharing practices.

Kasper, Helmut; Lehrer, Mark; Mühlbacher, Jürgen; Müller, Barbara

2013-02-01

This qualitative field study investigated cross-site knowledge sharing in a small sample of multinational corporations in three different MNC business contexts (global, multidomestic, transnational). The results disclose heterogeneous "worlds" of MNC knowledge sharing, ultimately raising the question as to whether the whole concept of MNC knowledge sharing covers a sufficiently unitary phenomenon to be meaningful. We derive a non-exhaustive typology of MNC knowledge-sharing practices: self-organizing knowledge sharing, technocratic knowledge sharing, and best practice knowledge sharing. Despite its limitations, this typology helps to elucidate a number of issues, including the latent conflict between two disparate theories of MNC knowledge sharing, namely "sender-receiver" and "social learning" theories (Noorderhaven & Harzing, 2009). More generally, we develop the term "knowledge contextualization" to highlight the way that firm-specific organizational features pre-define which knowledge is considered to be of special relevance for intra-organizational sharing.

Previous research yielded conflicting results about when children can accurately assess their epistemic states in different hiding tasks. In Experiment 1, ninety-two 3- to 7-year-olds were either shown which object was hidden inside a box, were totally ignorant about what it could be, or were presented with two objects one of which was being put inside (partial exposure). Even 3-year-olds could assess their epistemic states in the total ignorance and the complete knowledge task. However, only children older than 5 could assess their ignorance in the partial exposure task. In Experiment 2 with one hundred and one 3- to 7-year-olds, similar results were found for children under 5 years even when more objects were shown in partial exposure tasks. Implications for children's developing theory of knowledge are discussed. © 2012 The Authors. Child Development © 2012 Society for Research in Child Development, Inc.

Palten, Patricia E; Dudenhausen, Joachim W

2010-11-01

we evaluated what German-speaking women in Berlin know about umbilical cord blood banking (UCBB) and whether a correlation exists between women's knowledge about UCBB and level of education. we used the anonymous questionnaire given to German-speaking women in Berlin, Germany. a total of 300 questionnaires could be evaluated. Although three quarters of our population heard of UCBB, most had no further knowledge about the method. Only about one-third of the interviewed women were informed about whether certain diseases had been treated with umbilical cord blood (UCB) by the time the survey was being conducted, whereas 50-65% did not know how to answer these questions. women in Berlin were poorly educated about the usefulness, the costs and the methods of cryopreservation. To some extent there is a correlation between women's level of education and their knowledge regarding UCB.

The experimenters' regress reconsidered: Replication, tacit knowledge, and the dynamics of knowledge generation.

PubMed

Feest, Uljana

2016-08-01

This paper revisits the debate between Harry Collins and Allan Franklin, concerning the experimenters' regress. Focusing my attention on a case study from recent psychology (regarding experimental evidence for the existence of a Mozart Effect), I argue that Franklin is right to highlight the role of epistemological strategies in scientific practice, but that his account does not sufficiently appreciate Collins's point about the importance of tacit knowledge in experimental practice. In turn, Collins rightly highlights the epistemic uncertainty (and skepticism) surrounding much experimental research. However, I will argue that his analysis of tacit knowledge fails to elucidate the reasons why scientists often are (and should be) skeptical of other researchers' experimental results. I will present an analysis of tacit knowledge in experimental research that not only answers to this desideratum, but also shows how such skepticism can in fact be a vital enabling factor for the dynamic processes of experimental knowledge generation.

Esposito, Fabienne; Rochat, Lucien; Juillerat Van der Linden, Anne-Claude; Lekeu, Françoise; Charnallet, Annik; Van der Linden, Martial

2014-01-01

Apathy is common in aging and generally defined on the basis of three dimensions: lack of initiative, lack of interest and emotional blunting. Curiously, no study until now has examined the associations and dissociations between these dimensions in elderly people (with or without dementia). These questions were addressed in two studies. In the first study, we explored the distribution of scores and the relationships between the three dimensions of apathy in 56 patients with dementia, focusing mainly on lack of initiative and lack of interest. Apathy was hetero-evaluated with the Apathy Inventory (AI), a scale widely used to assess the apathy dimensions in aging. In the second study, given the AI's limitations, we investigated in more detail the relationship between lack of initiative and interest in 115 elderly people using a new questionnaire specifically designed to assess these two dimensions. Results showed that lack of initiative was closely related to lack of interest (Study 1). Although we used a more specific questionnaire, these facets of apathy did not constitute two separable dimensions, but reflected a common main factor of apathy in aging (Study 2). Thus, the distinction between lack of initiative and lack of interest seems questionable. Only a multifactorial approach that includes the various psychological factors involved in apathy would enable one to gain a better understanding of the different manifestations of apathy and to highlight possible dissociations between them.

A growing population of adolescents/young adults with eosinophilic esophagitis (EoE) and eosinophilic gastroenteritis (EGE) will need to transition from pediatric to adult health providers. Measuring health care transition (HCT) readiness is critical, but no studies have evaluated this process in EoE/EGE. We determined the scope and predictors of HCT knowledge in patients and parents with EoE/EGE and measured HCT readiness in adolescents/young adults. We conducted an online survey of patients 13 years or older and parents of patients with EoE/EGE who were diagnosed when 25 years or younger. Parents answered questions regarding their children and their own knowledge of HCT. HCT readiness was assessed in adolescents/young adults aged 13 to 25 years with the Self-Management and Transition to Adulthood with Rx Questionnaire (a 6-domain self-report tool) with a score range of 0 to 90. Four hundred fifty participants completed the survey: 205 patients and 245 parents. Included in the analysis (those diagnosed with EoE/EGE at age 25 years or younger) were 75 of 205 patients and children of 245 parent respondents. Overall, 78% (n = 52) of the patients and 76% (n = 187) of parents had no HCT knowledge. Mean HCT readiness score in adolescents/young adults (n = 50) was 30.4 ± 11.3 with higher scores in domains of provider communication and engagement during appointments. Mean parent-reported (n = 123) score was 35.6 ± 9.7 with higher scores in medication management and disease knowledge. There was a significant deficit in HCT knowledge, and HCT readiness scores were lower than other chronic health conditions. HCT preparation and readiness assessments should become a priority for adolescents/young adults with EoE/EGE and their parents.

The adequate knowledge required for handling an emergency without hospital setting at the site of the accident or emergency may not be sufficient as most medical schools do not have formal first aid training in the teaching curriculum. The aim of this study is to assess the level of knowledge of medical students in providing first aid care. This cross-sectional study was conducted during May 2011 among 152 medical students. Data was collected using a self-administered questionnaire. Based on the scores obtained in each condition requiring first aid, the overall knowledge was graded as good, moderate and poor. Only 11.2% (17/152) of the total student participants had previous exposure to first aid training. Good knowledge about first aid was observed in 13.8% (21/152), moderate knowledge in 68.4% (104/152) and poor knowledge in 17.8% (27/152) participants. Analysis of knowledge about first aid management in select conditions found that 21% (32/152) had poor knowledge regarding first aid management for shock and for gastro esophageal reflux disease and 20.4% (31/152) for epistaxis and foreign body in eyes. All students felt that first aid skills need to be taught from the school level onwards and all of them were willing to enroll in any formal first aid training sessions. The level of knowledge about first aid was not good among majority of the students. The study also identified the key areas in which first aid knowledge was lacking. There is thus a need for formal first aid training to be introduced in the medical curriculum.

A 'curse of knowledge' in the absence of knowledge? People misattribute fluency when judging how common knowledge is among their peers.

2017-09-01

Knowledge can be a curse: Once we have acquired a particular item of knowledge it tends to bias, or contaminate, our ability to reason about a less informed perspective (referred to as the 'curse of knowledge' or 'hindsight bias'). The mechanisms underlying the curse of knowledge bias are a matter of great import and debate. We highlight two mechanisms that have been proposed to underlie this bias-inhibition and fluency misattribution. Explanations that involve inhibition argue that people have difficulty fully inhibiting or suppressing the content of their knowledge when trying to reason about a less informed perspective. Explanations that involve fluency misattribution focus on the feelings of fluency with which the information comes to mind and the tendency to misattribute the subjective feelings of fluency associated with familiar items to the objective ease or foreseeability of that information. Three experiments with a total of 359 undergraduate students provide the first evidence that fluency misattribution processes are sufficient to induce the curse of knowledge bias. These results add to the literature on the many manifestations of the curse of knowledge bias and the many types of source misattributions, by revealing their role in people's judgements of how common, or widespread, one's knowledge is. The implications of these results for cognitive science and social cognition are discussed. Copyright © 2017. Published by Elsevier B.V.

The present study examined the knowledge of Alzheimer's disease and correlates of the disease knowledge among Vietnamese Americans. Cross-sectional survey interviews were conducted with 95 middle-aged and older Vietnamese Americans. Vietnamese Americans showed limited knowledge about Alzheimer's disease. Normalization of Alzheimer's disease in old age was prevalent. They lacked knowledge about treatment and cure of Alzheimer's disease. Those who reside longer in the U.S. and are more exposed to Alzheimer's disease are likely to have higher levels of Alzheimer's disease knowledge. Our study identified current Alzheimer's disease knowledge level and status, and areas of misconceptions and knowledge gaps among Vietnamese Americans, calling for urgent needs for educational outreach to improve knowledge about Alzheimer's disease among Vietnamese Americans. Information about who can be more or less knowledgeable about Alzheimer's disease can be used to strategize and tailor outreach efforts for different segments of the Vietnamese American population.

Prevention is better than cure. Public health plays an important role in promoting prevent medicine. To obtain the abilities to provide appropriate nursing services, learning public health is necessary for students who want to become registered nurses. When teachers teach public health to nursing students, it is important to motivate them to learn it. Therefore, we investigated the reasons for the lack of motivation to learn public health by conducting a questionnaire survey. The subjects were female nursing students in 29 vocational schools in Kanagawa and Chiba prefectures of Japan that allow graduation after a 3-year study period. We asked the students whether or not they had completed the subject of public health and analyzed those students who answered affirmatively. We analyzed 1,553 respondents whose average age was 22.6 ± 5.2 years (range, 18 to 45). Using factor analysis, we discovered the 5 reasons that lead to the lack of nursing students' motivation to learn public health: "Difficulties acquiring knowledge of public health," "Inappropriate attitudes of public health teachers," "Thinking lightly about the national examination in the field of public health," "Lack of understanding the importance of learning public health," and "Future plans that do not specialize in public health." Using multiple linear regression analysis, these 5 reasons were significant predictors for the lack of students' motivation. Older students also had significantly less motivation to learn public health than did younger students. When teachers instruct their students, they should teach public health better with the present knowledge.

Young, Robert S; Hinami, Keiki; Arseven, Adnan; Jain, Bijal; Williams, Mark V

2012-10-01

Delirium is frequently missed by inpatient health care providers despite the existence of a highly sensitive and specific assessment for delirium, the Confusion Assessment Method (CAM). The CAM, due to its test characteristics and ease of use, is an ideal physician instrument for systematic inpatient delirium screening; however, little is known about hospitalists' knowledge of the CAM. A short survey with items assessing respondents' perceptions of delirium detection, familiarity and proficiency with the CAM, and knowledge of the CAM algorithm was administered at a regional hospital medicine conference. Participants included a group of hospital medicine providers comprised of physicians (79.9%), nurse practitioners (7.2%), and physician assistants (12.9%). Results in the form of counts, percentages, and distributions of Likert scale responses and multiple-choice questions were reported. Of 157 surveys distributed, 94% (n = 147) were returned. Approximately 3 of 4 of providers (77%) reported encountering delirium at least once per week, with 45% reporting encountering delirium more than once per week. Yet, 82% had never used or heard of the CAM; only 3 respondents felt proficient with its use. Of the knowledge items, 4 respondents were able to correctly indicate the 4 clinical features of the CAM. Only 1 respondent was able to answer all knowledge items correctly. The respondents also agreed that nurses have an important role in delirium detection (65%), delirium diagnosis is often delayed (68%), and reported that not knowing patients' baseline cognitive status (53%) and having difficulty separating delirium from dementia or psychiatric illnesses (25%) were important challenges to delirium diagnosis. Hospital medicine providers who responded to the survey reported encountering delirium often in their clinical practice; however, they also reported poor familiarity with and demonstrated poor knowledge of the CAM. These results suggest a potential barrier to systematic

Background Research utilization is part of evidence-based practice referring to the process of reviewing and critiquing scientific research and applying the findings to one's own clinical practice. Many studies on research utilization have been conducted with doctors and nurses, but to our knowledge, none have been investigated amongst pharmacists. Objective To assess research utilization and its barriers among pharmacists and identify potential influencing factors. Setting Malaysia. Methods This cross-sectional survey was administered online and by mail to a convenient sample of pharmacists working in hospitals, health clinics, and retail pharmacies in rural and urban areas. Main outcome measure Pharmacists' research utilization knowledge, attitudes, and practices. Results Six hundred surveys were mailed to potential respondents, and 466 were returned (77.7% response rate). Twenty-eight respondents completed the survey online. The respondents' research utilization knowledge, attitudes, and practices were found to be moderate. Research utilization was associated with respondents' knowledge and attitude scores (P < 0.001). When factors related to research utilization were modelled, higher educational level was associated with higher level of research utilization (P < 0.001) while less involvement in journal clubs, more years of service (3-7 years and more than 7 years) were associated with low and moderate research utilization, respectively. The main reported barrier to research utilization was lack of sufficient authority to change patient care procedures. Conclusion Pharmacists' research utilization knowledge, attitudes, and practices can be improved by encouraging pharmacists to pursue higher degrees, promoting active participation in institutions' journal clubs, and introducing senior clinical pharmacist specialization.

The present study was done to assess knowledge about osteoporosis in learned Indian women, identify their source of knowledge and to study the correlation of level of knowledge with other variables. A total of 73 female staff members (average age 44.7 years) of a teaching institute completed the Osteoporosis Questionnaire (OPQ). The mean +/- SD of total score for the sample was 4.1 +/- 4.1 (range -8 to 15; maximum possible score 20). The correct definition of osteoporosis was given by 74%, but there was general lack of awareness in all the areas assessed. There was statistically significant difference in the total score depending on the faculty of education, with staff members from the science faculty having the maximum mean score (p < 0.05). We found no influence of age, menopausal status, previous history of fracture and family history of osteoporosis on the level of knowledge. Media (74%) was the commonest source of knowledge followed by friends (49%) and doctors (25%). This study highlights the general lack of knowledge about osteoporosis in learned Indian women and also the need for increased involvement of medical professionals in patient education.

Friedman, Ariella A; Ahmed, Haris; Gitlin, Jordan S; Palmer, Lane S

2016-06-01

Testicular torsion leads to orchiectomy in 30-50% of cases, which may cause psychological upset and parental guilt over a potentially avertable outcome. Presentation delay is an important modifiable cause of orchiectomy; yet, families are not routinely educated about torsion or its urgency. The present study assessed parental knowledge regarding acute scrotal pain. An anonymous survey was distributed to parents in Urology and ENT offices, asking about their children's gender and scrotal pain history, urgency of response to a child's acute scrotal pain, and familiarity with testicular torsion. Surveys of 479 urology and 59 ENT parents were analyzed. The results between the two were not statistically different. Among the urology parents, 34% had heard of testicular twisting/torsion, most commonly through friends, relatives or knowing someone with torsion (35%); only 17% were informed by pediatricians (Summary Figure). Parents presenting for a child's scrotal pain were significantly more likely to have heard of torsion (69%) than those presenting for other reasons (30%, OR 5.24, P < 0.0001). Only 13% of parents of boys had spoken with their children about torsion. Roughly three quarters of them would seek emergent medical attention - by day (75%) or night (82%) - for acute scrotal pain. However, urgency was no more likely among those who knew about torsion. This was the first study to assess parental knowledge of the emergent nature of acute scrotal pain in a non-urgent setting, and most closely approximating their level of knowledge at the time of pain onset. It also assessed parents' hypothetical responses to the scenario, which was markedly different than documented presentation times, highlighting a potential area for improvement in presentation times. Potential limitations included lack of respondent demographic data, potential sampling bias of a population with greater healthcare knowledge or involvement, and assessment of parents only. Parental knowledge of

Fetal circulatory responses to oxygen lack.

PubMed

Jensen, A; Berger, R

1991-10-01

The knowledge on fetal and neonatal circulatory physiology accumulated by basic scientists and clinicians over the years has contributed considerably to the recent decline of perinatal morbidity and mortality. This review will summarize the peculiarities of the fetal circulation, the distribution of organ blood flow during normoxemia, and that during oxygen lack caused by various experimental perturbations. Furthermore, the relation between oxygen delivery and tissue metabolism during oxygen lack as well as evidence to support a new concept will be presented along with the principal cardiovascular mechanisms involved. Finally, blood flow and oxygen delivery to the principal fetal organs will be examined and discussed in relation to organ function. The fetal circulatory response to hypoxemia and asphyxia is a centralization of blood flow in favour of the brain, heart, and adrenals and at the expense of almost all peripheral organs, particularly of the lungs, carcass, skin and scalp. This response is qualitatively similar but quantitatively different under various experimental conditions. However, at the nadir of severe acute asphyxia the circulatory centralization cannot be maintained. Then there is circulatory decentralization, and the fetus will experience severe brain damage if not expire unless immediate resuscitation occurs. Future work in this field will have to concentrate on the important questions, what factors determine this collapse of circulatory compensating mechanisms in the fetus, how does it relate to neuronal damage, and how can the fetal brain be pharmacologically protected against the adverse effects of asphyxia.

Background: Smoking is the single most important public health challenge facing the National Health Service. The detrimental effects on the general health of tobacco smoking are well documented. Smoking is a primary risk factor for oral cancer and many oral diseases. Dental professional scan plays an important role in preventing adverse health effects by promoting smoking cessation. Objective: To assess the knowledge, attitude, and practice among clinical dental students in giving smoking cessation advice and to explore the barriers to this activity. Materials and Methods: A total of 262 clinical dental trainee of two dental colleges (College of Dental Sciences and Bapuji Dental College) of Davangere city were included in the survey. A self-administered questionnaire was administered to assess the knowledge, attitude, and practice toward Tobacco Cessation Advise. Results: Among the 262 participants in the study, around 51% said they know about Nicotine Replacement Therapy, and among them, only 4.6% were aware of the options available in the market. When asked about 5A's of tobacco cessation, only 35.5% were aware of it. Similarly, when asked about 5R's of tobacco cessation, 48.5% were unaware of it. Conclusions: The respondents did not have sufficient knowledge regarding tobacco cessation advice. With patient's disinterest and lack of time being quoted as the important barriers in providing tobacco cessation advice, it is highly recommended that there is need to incorporate few chapters on tobacco, its effect and cessation of habit in the undergraduate dental curriculum with simultaneous application of the same in clinical practice.

The intestinal epithelium is the first physiological barrier breached by the Gram-positive facultative pathogen Listeria monocytogenes during an in vivo infection. Listeria monocytogenes binds to the epithelial host cell receptor E-cadherin, which mediates a physical link between the bacterium and filamentous actin (F-actin). However, the importance of anchoring the bacterium to F-actin through E-cadherin for bacterial invasion has not been tested directly in epithelial cells. Here we demonstrate that depleting αE-catenin, which indirectly links E-cadherin to F-actin, did not decrease L. monocytogenes invasion of epithelial cells in tissue culture. Instead, invasion increased due to increased bacterial adhesion to epithelial monolayers with compromised cell–cell junctions. Furthermore, expression of a mutant E-cadherin lacking the intracellular domain was sufficient for efficient L. monocytogenes invasion of epithelial cells. Importantly, direct biotin-mediated binding of bacteria to surface lipids in the plasma membrane of host epithelial cells was sufficient for uptake. Our results indicate that the only requirement for L. monocytogenes invasion of epithelial cells is adhesion to the host cell surface, and that E-cadherin–mediated coupling of the bacterium to F-actin is not required.

In order to study the role of sufficient phosphorus (P) in biodiesel production by microalgae, Phaeodactylum tricornutum were cultivated in six different media treatments with combination of nitrogen (N) sufficiency/deprivation and phosphorus sufficiency/limitation/deprivation. Profiles of N and P, biomass, and fatty acids (FAs) content and compositions were measured during a 7-day cultivation period. The results showed that the FA content in microalgae biomass was promoted by P deprivation. However, statistical analysis showed that FA productivity had no significant difference (p = 0.63, >0.05) under the treatments of N deprivation with P sufficiency (N-P) and N deprivation with P deprivation (N-P-), indicating P sufficiency in N deprivation medium has little effect on increasing biodiesel productivity from P. triornutum. It was also found that the P absorption in N-P medium was 1.41 times higher than that in N sufficiency and P sufficiency (NP) medium. N deprivation with P limitation (N-P-l) was the optimal treatment for producing biodiesel from P. triornutum because of both the highest FA productivity and good biodiesel quality.

Minimal sufficient positive-operator valued measure on a separable Hilbert space

Kuramochi, Yui, E-mail: kuramochi.yui.22c@st.kyoto-u.ac.jp

We introduce a concept of a minimal sufficient positive-operator valued measure (POVM), which is the least redundant POVM among the POVMs that have the equivalent information about the measured quantum system. Assuming the system Hilbert space to be separable, we show that for a given POVM, a sufficient statistic called a Lehmann-Scheffé-Bahadur statistic induces a minimal sufficient POVM. We also show that every POVM has an equivalent minimal sufficient POVM and that such a minimal sufficient POVM is unique up to relabeling neglecting null sets. We apply these results to discrete POVMs and information conservation conditions proposed by the author.

2017-05-01

Teachers need various types of knowledge in order to deliver various fraction concepts at elementary level. In this paper, Balls' framework (2008) or, Mathematical Knowledge for Teaching (MKT) is used as benchmark guideline. This paper investigates and explores component of MKT knowledge among eight experienced teachers of the primary school. Data was collected using paper pencil test, interview and video recording. This paper, narrowed to teacher's knowledge and their practices while teaching of various fractions concepts using diagrammatical approach in present of MKT. The data gathered from teachers were analyzed using thematic analysis techniques. The results indicated that teachers lack various components of MKT knowledge as a proposal by various researchers and assumed that teaching as procedural more than enough due to lack of deep understanding of mathematics and the various types of MKT is not required due to the present of practices in the mathematics classroom.

Sewer deterioration modeling with condition data lacking historical records.

PubMed

Egger, C; Scheidegger, A; Reichert, P; Maurer, M

2013-11-01

Accurate predictions of future conditions of sewer systems are needed for efficient rehabilitation planning. For this purpose, a range of sewer deterioration models has been proposed which can be improved by calibration with observed sewer condition data. However, if datasets lack historical records, calibration requires a combination of deterioration and sewer rehabilitation models, as the current state of the sewer network reflects the combined effect of both processes. Otherwise, physical sewer lifespans are overestimated as pipes in poor condition that were rehabilitated are no longer represented in the dataset. We therefore propose the combination of a sewer deterioration model with a simple rehabilitation model which can be calibrated with datasets lacking historical information. We use Bayesian inference for parameter estimation due to the limited information content of the data and limited identifiability of the model parameters. A sensitivity analysis gives an insight into the model's robustness against the uncertainty of the prior. The analysis reveals that the model results are principally sensitive to the means of the priors of specific model parameters, which should therefore be elicited with care. The importance sampling technique applied for the sensitivity analysis permitted efficient implementation for regional sensitivity analysis with reasonable computational outlay. Application of the combined model with both simulated and real data shows that it effectively compensates for the bias induced by a lack of historical data. Thus, the novel approach makes it possible to calibrate sewer pipe deterioration models even when historical condition records are lacking. Since at least some prior knowledge of the model parameters is available, the strength of Bayesian inference is particularly evident in the case of small datasets. Copyright © 2013 Elsevier Ltd.

2017-11-17

This study explores medicinal plant knowledge and use among Muslim women in the city of Mecca, Saudi Arabia. Ethnobotanical research in the region has focused on rural populations and male herbal healers in cities, and based on these few studies, it is suggested that medicinal plant knowledge may be eroding. Here, we document lay, female knowledge of medicinal plants in an urban centre, interpreting findings in the light of the growing field of urban ethnobotany and gendered knowledge and in an Islamic context. Free-listing, structured and semi-structured interviews were used to document the extent of medicinal plant knowledge among 32 Meccan women. Vernacular names, modes of preparation and application, intended therapeutic use and emic toxicological remarks were recorded. Women were asked where they learnt about medicinal plants and if and when they preferred using medicinal plants over biomedical resources. Prior informed consent was always obtained. We compared the list of medicinal plants used by these Meccan women with medicinal plants previously documented in published literature. One hundred eighteen vernacular names were collected, corresponding to approximately 110 plants, including one algae. Of these, 95 were identified at the species level and 39 (41%) had not been previously cited in Saudi Arabian medicinal plant literature. Almost one half of the plants cited are food and flavouring plants. Meccan women interviewed learn about medicinal plants from their social network, mass media and written sources, and combine biomedical and medicinal plant health care. However, younger women more often prefer biomedical resources and learn from written sources and mass media. The fairly small number of interviews conducted in this study was sufficient to reveal the singular body of medicinal plant knowledge held by women in Mecca and applied to treat common ailments. Plant availability in local shops and markets and inclusion in religious texts seem to shape the

Athletes require sufficient nutrition knowledge and skills to enable appropriate selection and consumption of food and fluids to meet their health, body composition, and performance needs. This article reports the nutrition knowledge and dietary habits of male football (soccer) players in Australia. Players age 18 years and older were recruited from 1 A-League club (professional) and 4 National Premier League clubs (semiprofessional). No significant difference in general nutrition knowledge (GNK; 54.1% ± 13.4%; 56.8% ± 11.7%; M ± SD), t(71) = -0.91, p = .37, or sports nutrition knowledge (SNK; 56.9% ± 15.5%; 61.3% ± 15.9%), t(71) = -1.16, p = .25) were noted between professional (n = 29) and semiprofessional (n = 44) players. In general, players lacked knowledge in regard to food sources and types of fat. Although nutrition knowledge varied widely among players (24.6-82.8% correct responses), those who had recently studied nutrition answered significantly more items correctly than those who reported no recent formal nutrition education (62.6% ± 11.9%; 54.0% ± 11.4%), t(67) = 2.88, p = .005). Analysis of 3-day estimated food diaries revealed both professionals (n = 10) and semiprofessionals (n = 31) consumed on average less carbohydrate (3.5 ± 0.8 gC/kg; 3.9 ± 1.8 gC/kg) per day than football-specific recommendations (FIFA Medical and Assessment Research Centre [F-MARC]: 5-10 gC/kg). There was a moderate, positive correlation between SNK and carbohydrate intake (n = 41, ρ = 0.32, p = .04), indicating that players who exhibited greater SNK had higher carbohydrate intakes. On the basis of these findings, male football players in Australia would benefit from nutrition education targeting carbohydrate and fat in an attempt to improve nutrition knowledge and dietary practices.

Lack of genetic polymorphism among peregrine falcons Falco peregrinus of Fiji

Talbot, Sandra; Palmer, Angela G.; Sage, George K.; Sonsthagen, Sarah A.; Swem, Ted; Brimm, Daniel J.; White, Clayton M

2014-01-01

We compared levels of genetic diversity and isolation among peregrine falcons Falco peregrinus from two South Pacific island complexes (Fiji and Vanuatu: F. p. nesiotes), relative to other island and mainland populations. Fragment data from 12 microsatellite loci and sequence information from the control region of the mitochondrial DNA indicated levels of genetic variation in the South Pacific populations were lower than other island and mainland populations. Indeed, diversity varied from extremely low (Vanuatu) to completely absent (Fiji). We find little support for a hypothesis that populations on Fiji or Vanuatu were colonized via Australia. The complete lack of polymorphism in peregrine falcons of Fiji is remarkable, and to our knowledge has not been observed in a natural avian population. This lack of polymorphism, and the inability to test for decrease in polymorphism using museum samples, precludes testing whether the lack of genetic diversity in the population on Fiji is due to a recent bottleneck, or sustained isolation over evolutionary time. Increased fertility in eggs of Fiji peregrines upon outbreeding with males from other areas is consistent with inbreeding depression within a population typified by heterozygote deficiency.

Sufficient conditions for uniqueness of the weak value

NASA Astrophysics Data System (ADS)

Dressel, J.; Jordan, A. N.

2012-01-01

We review and clarify the sufficient conditions for uniquely defining the generalized weak value as the weak limit of a conditioned average using the contextual values formalism introduced in Dressel, Agarwal and Jordan (2010 Phys. Rev. Lett. 104 240401). We also respond to criticism of our work by Parrott (arXiv:1105.4188v1) concerning a proposed counter-example to the uniqueness of the definition of the generalized weak value. The counter-example does not satisfy our prescription in the case of an underspecified measurement context. We show that when the contextual values formalism is properly applied to this example, a natural interpretation of the measurement emerges and the unique definition in the weak limit holds. We also prove a theorem regarding the uniqueness of the definition under our sufficient conditions for the general case. Finally, a second proposed counter-example by Parrott (arXiv:1105.4188v6) is shown not to satisfy the sufficiency conditions for the provided theorem.

Reassessing Rogers' necessary and sufficient conditions of change.

PubMed

Watson, Jeanne C

2007-09-01

This article reviews the impact of Carl Rogers' postulate about the necessary and sufficient conditions of therapeutic change on the field of psychotherapy. It is proposed that his article (see record 2007-14630-002) made an impact in two ways; first, by acting as a spur to researchers to identify the active ingredients of therapeutic change; and, second, by providing guidelines for therapeutic practice. The role of the necessary and sufficient conditions in process-experiential therapy, an emotion-focused therapy for individuals, and their limitations in terms of research and practice are discussed. It is proposed that although the conditions are necessary and important in promoting clients' affect regulation, they do not take sufficient account of other moderating variables that affect clients' response to treatment and may need to be balanced with more structured interventions. Notwithstanding, Rogers highlighted a way of interacting with clients that is generally acknowledged as essential to effective psychotherapy practice.

Assessing sufficiency of thermal riverscapes for resilient ...

EPA Pesticide Factsheets

Resilient salmon populations require river networks that provide water temperature regimes sufficient to support a diversity of salmonid life histories across space and time. Efforts to protect, enhance and restore watershed thermal regimes for salmon may target specific locations and features within stream networks hypothesized to provide disproportionately high-value functional resilience to salmon populations. These include relatively small-scale features such as thermal refuges, and larger-scale features such as entire watersheds or aquifers that support thermal regimes buffered from local climatic conditions. Quantifying the value of both small and large scale thermal features to salmon populations has been challenged by both the difficulty of mapping thermal regimes at sufficient spatial and temporal resolutions, and integrating thermal regimes into population models. We attempt to address these challenges by using newly-available datasets and modeling approaches to link thermal regimes to salmon populations across scales. We will describe an individual-based modeling approach for assessing sufficiency of thermal refuges for migrating salmon and steelhead in large rivers, as well as a population modeling approach for assessing large-scale climate refugia for salmon in the Pacific Northwest. Many rivers and streams in the Pacific Northwest are currently listed as impaired under the Clean Water Act as a result of high summer water temperatures. Adverse effec

Role of exponential type random invexities for asymptotically sufficient efficiency conditions in semi-infinite multi-objective fractional programming.

First a new notion of the random exponential Hanson-Antczak type [Formula: see text]-V-invexity is introduced, which generalizes most of the existing notions in the literature, second a random function [Formula: see text] of the second order is defined, and finally a class of asymptotically sufficient efficiency conditions in semi-infinite multi-objective fractional programming is established. Furthermore, several sets of asymptotic sufficiency results in which various generalized exponential type [Formula: see text]-V-invexity assumptions are imposed on certain vector functions whose components are the individual as well as some combinations of the problem functions are examined and proved. To the best of our knowledge, all the established results on the semi-infinite aspects of the multi-objective fractional programming are new, which is a significantly new emerging field of the interdisciplinary research in nature. We also observed that the investigated results can be modified and applied to several special classes of nonlinear programming problems.

Knowledge, attitude and practice of mothers regarding their own and children's dental health--a tertiary care hospital based study.

Mothers play a basic role in the dental health of children. They decide whether their children need dental treatment or not. The aims of this study were to assess mothers' knowledge and practices regarding children's dental health and to determine association of mothers own attitude and their attitude towards children's dental health. A cross sectional study was conducted in the Aga Khan University Hospital (AKUH), Karachi, Pakistan in which 207 mothers completed a self-administered structured questionnaire. Inclusion criteria were respondents having children between 2 and 5 years of age and exclusion criteria were respondents having physical or mentally handicapped children. SPSS-16 was used for data analysis. Chi Square test was used to determine association between maternal own dental attitude and their attitude and knowledge about children dental health with p < or = 0.05 as statistically significant. Majority of the mothers used to visit dentists for themselves in the case of problems and they thought the same for their children (p < 0.001). A statistically significant association also existed between mothers and children tooth brushing frequency (p < 0.001). Mothers visiting Aga Khan University Hospital, lack sufficient knowledge regarding timings of the children's first dental visit and the importance of limiting frequency of in-between meals snacks consumed by their children.

Photodynamic therapy has been increasingly applied in clinical cancer treatments. However, native hypoxic tumoural microenvironment and lacking oxygen supply are the major barriers hindering photodynamic reactions. To solve this problem, we have developed biomimetic artificial red cells by loading complexes of oxygen-carrier (hemoglobin) and photosensitizer (indocyanine green) for boosted photodynamic strategy. Such nanosystem provides a coupling structure with stable self-oxygen supply and acting as an ideal fluorescent/photoacoustic imaging probe, dynamically monitoring the nanoparticle biodistribution and the treatment of PDT. Upon exposure to near-infrared laser, the remote-triggered photosensitizer generates massive cytotoxic reactive oxygen species (ROS) with sufficient oxygen supply. Importantly, hemoglobin is simultaneously oxidized into the more active and resident ferryl-hemoglobin leading to persistent cytotoxicity. ROS and ferryl-hemoglobin synergistically trigger the oxidative damage of xenograft tumour resulting in complete suppression. The artificial red cells with self-monitoring and boosted photodynamic efficacy could serve as a versatile theranostic platform.

Assessing Knowledge Sharing Among Academics: A Validation of the Knowledge Sharing Behavior Scale (KSBS).

There is a belief that academics tend to hold on tightly to their knowledge and intellectual resources. However, not much effort has been put into the creation of a valid and reliable instrument to measure knowledge sharing behavior among the academics. To apply and validate the Knowledge Sharing Behavior Scale (KSBS) as a measure of knowledge sharing behavior within the academic community. Respondents (N = 447) were academics from arts and science streams in 10 local, public universities in Malaysia. Data were collected using the 28-item KSBS that assessed four dimensions of knowledge sharing behavior namely written contributions, organizational communications, personal interactions, and communities of practice. The exploratory factor analysis showed that the items loaded on the dimension constructs that they were supposed to represent, thus proving construct validity. A within-factor analysis revealed that each set of items representing their intended dimension loaded on only one construct, therefore establishing convergent validity. All four dimensions were not perfectly correlated with each other or organizational citizenship behavior, thereby proving discriminant validity. However, all four dimensions correlated with organizational commitment, thus confirming predictive validity. Furthermore, all four factors correlated with both tacit and explicit sharing, which confirmed their concurrent validity. All measures also possessed sufficient reliability (α > .70). The KSBS is a valid and reliable instrument that can be used to formally assess the types of knowledge artifacts residing among academics and the degree of knowledge sharing in relation to those artifacts. © The Author(s) 2014.

Epidermal jasmonate perception is sufficient for all aspects of jasmonate-mediated male fertility in Arabidopsis.

PubMed

Jewell, Jeremy B; Browse, John

2016-03-01

Jasmonate (JA) signaling is essential for several environmental responses and reproductive development in many plant species. In Arabidopsis thaliana, the most obvious phenotype of JA biosynthetic and perception mutants is profound sporophytic male sterility characterized by failure of stamen filament elongation, severe delay of anther dehiscence and pollen inviability. The site of action of JA in the context of reproductive development has been discussed, but the ideas have not been tested experimentally. To this end we used targeted expression of a COI1-YFP transgene in the coi1-1 mutant background. As COI1 is an essential component of the JA co-receptor complex, the null coi1-1 mutant is male sterile due to lack of JA perception. We show that expression of COI1-YFP in the epidermis of the stamen filament and anther in coi1 mutant plants is sufficient to rescue filament elongation, anther dehiscence and pollen viability. In contrast, filament expression alone or expression in the tapetum do not restore dehiscence and pollen viability. These results demonstrate that epidermal JA perception is sufficient for anther function and pollen viability, and suggest the presence of a JA-dependent non-autonomous signal produced in the anther epidermis to synchronize both anther dehiscence and pollen maturation. © 2016 The Authors The Plant Journal © 2016 John Wiley & Sons Ltd.

2005-01-01

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.

Knowledge-based verification of clinical guidelines by detection of anomalies.

PubMed

Duftschmid, G; Miksch, S

2001-04-01

As shown in numerous studies, a significant part of published clinical guidelines is tainted with different types of semantical errors that interfere with their practical application. The adaptation of generic guidelines, necessitated by circumstances such as resource limitations within the applying organization or unexpected events arising in the course of patient care, further promotes the introduction of defects. Still, most current approaches for the automation of clinical guidelines are lacking mechanisms, which check the overall correctness of their output. In the domain of software engineering in general and in the domain of knowledge-based systems (KBS) in particular, a common strategy to examine a system for potential defects consists in its verification. The focus of this work is to present an approach, which helps to ensure the semantical correctness of clinical guidelines in a three-step process. We use a particular guideline specification language called Asbru to demonstrate our verification mechanism. A scenario-based evaluation of our method is provided based on a guideline for the artificial ventilation of newborn infants. The described approach is kept sufficiently general in order to allow its application to several other guideline representation formats.

The aim of this study was to investigate dentist's approaches to the use of splint therapy for myofascial pain, bruxism, and temporomandibular joint (TMJ) disorders and to assessment of treatment modalities. A 12-item questionnaire was developed to determine dentists' knowledge of TMJ disorders and approaches for occlusal splint treatments. The researchers spoke with each dentist included in the study at his/her clinic or by telephone to assess their immediate knowledge and approach to the TMJ disorders. Chi-squared test was performed to analyze the values. The confidence interval was set as 95%. A total of 370 dentists working in Turkey were participated in this study. The most common splint application reason for occlusal splint treatment was bruxism (77.8%) while TMJ pain was very rare (%1.4). The use of hard splint ratios for 0-5 years of professional experience was 57.0%, 42.4.0%, and 26.8% for the experience of 5-15 years and over 15 years groups, respectively (P < 0.001). While the dentists' with sufficient knowledge soft splint application rates were 11.6%, hard splint application rates were 43.4% for the dentists with sufficient knowledge. Occlusion adjustment rate of dentists who practice in all three groups was under 16.0%. The knowledge of the dentists about TMJ disorders and occlusal splint therapy were found to be insufficient. Their knowledge decreased with increasing experience.

Concept analysis: lack of anonymity.

Swan, Marilyn A; Hobbs, Barbara B

2017-05-01

To re-examine and expand understanding of the concept 'lack of anonymity' as a component of rural nursing theory. Early healthcare literature reports lack of anonymity as part of social and working environments, particularly rural nursing. Rural nursing theory included the first published concept analysis on lack of anonymity but lacked empirical referents. Workforce, societal and rural healthcare changes support an updated analysis. To further understand lack of anonymity, its present day use and applicability to diverse environments, research from multiple disciplines was reviewed. Concept analysis. A literature search using eight terms in eleven databases was conducted of literature published between 2008-2013. Walker and Avant's concept analysis methodology guided the analysis. The previous concept analysis is supported in part by current literature. The defining attributes, 'identifiable', 'establishing boundaries for public and private self and interconnectedness' in a community were updated. Updated antecedents include: (i) environmental context; (ii) opportunities to become visible; (iii) developing relationships and (iv) unconscious or limited awareness of public or personal privacy. Consequences are: (i) familiarity; (ii) visibility; (iii) awareness of privacy and (iv) manage or balance of lack of anonymity. Cases were constructed and empirical referents identified. The concept of lack of anonymity was updated; portions of the original definition remain unchanged. Empirical referents reveal the defining attributes in daily life and may guide future research on the effect of lack of anonymity on nursing practice. This analysis advances the conceptual understanding of rural nursing theory. © 2016 John Wiley & Sons Ltd.

2017-08-01

Electroconvulsive therapy (ECT) is one of the commonly used treatment modalities for patients with severe mental disorders. However, acceptance of ECT by the patient and relatives often depends on how the health-care professionals themselves present the treatment modality to the patients and their relatives. There is a lack of information about the knowledge and attitude toward ECT among health professionals. This study aimed to evaluate the knowledge about and attitude toward ECT among nursing students. Knowledge of and attitudes toward ECT among nursing students were assessed using ECT knowledge and attitude questionnaires. The study included 183 nursing students. Majority ( n = 62; 60.8%) of the participants obtained information about ECT from media (movies, television, print media, etc.). None of the students had full knowledge about ECT. Although a significant proportion of students had knowledge about the ECT procedure and consent procedure, majority of them had poor knowledge about the effectiveness, mechanism of action, indications, and side effects of ECT. Negative attitudes were also highly prevalent, with more than two-thirds of the participants having negative attitudes toward ECT on more than half of the attitude items of the scale. Total knowledge score positively correlated with total attitude score, suggesting that higher knowledge was associated with more positive attitude. Although nursing students have knowledge about basic ECT procedure and consent, they lack knowledge about the effectiveness, mechanism of action, indications, and side effects of ECT. Negative attitude toward ECT is also highly prevalent among nursing students. Accordingly, there is a need to improve the knowledge and address the negative attitude of nursing students, which may ultimately lead to better acceptance of the treatment.

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.

Pradhan, Prajal; Lüdeke, Matthias K B; Reusser, Dominik E; Kropp, Juergen P

2014-08-19

This study explores the potential for regions to shift to a local food supply using food self-sufficiency (FSS) as an indicator. We considered a region food self-sufficient when its total calorie production is enough to meet its demand. For future scenarios, we considered population growth, dietary changes, improved feed conversion efficiency, climate change, and crop yield increments. Starting at the 5' resolution, we investigated FSS from the lowest administrative levels to continents. Globally, about 1.9 billion people are self-sufficient within their 5' grid, while about 1 billion people from Asia and Africa require cross-continental agricultural trade in 2000. By closing yield gaps, these regions can achieve FSS, which also reduces international trade and increases a self-sufficient population in a 5' grid to 2.9 billion. The number of people depending on international trade will vary between 1.5 and 6 billion by 2050. Climate change may increase the need for international agricultural trade by 4% to 16%.

Lack of knowledge is the major reason for non-compliance with correct healthcare-associated infections (HAI) prevention procedures. The aim of this study was to evaluate knowledge of the Dental School (DSS) and Dental Hygiene (DHS) students with regard to the prevention of HAI, as basic knowledge for improving and harmonizing the educational content in the different Italian Universities. A cross-sectional study was carried out using an anonymous questionnaire that was completed by DSS (I, II, III, IV, and V year) in seven Universities and DHS (I, II, and III year) in three Universities. The questions dealt with three specific areas: healthcare-associated infections, standard precautions and hand hygiene. Factors associated with an unacceptable level of knowledge (score <17.5) were analyzed using a logistic regression model. A p value <0.05 was considered to be significant. Five hundred and four questionnaires were collected: 81.5% for DSS and 18.5% for DHS. Mean overall score (±DS) achieved by the total number of students was 18.2±2.93 on an overall perfect score of 25; 18.2±3.04 for DSS and 17.8±2.31 for DHS. Stratifying by area, the average score 2.7±1.07 (53%) for HAI, 10.3±1.61 (85.9%) for standard precautions, and 5.2±1.44 (64.8%) for hand hygiene was observed. A significantly different level of knowledge (p<0.001) between DSS and DHS was observed only for HAI (2.8±1.07 for DSS vs 2.1±0.96 for DHS). Significant differences among the academic years were found only for DSS concerning HAI and standard precautions. The logistic regression model showed that an age <23 years was a risk factor for lack of knowledge on HAI, but a protective factor for lack of knowledge about standard precautions and hand hygiene; attending DH degree course was associated with lack of knowledge on HAI. Although the overall score obtained both by DSS and DHS indicated an acceptable level of knowledge, lack of knowledge was highlighted, in particular, for hand hygiene. Therefore

Clinical knowledge governance: the international perspective.

PubMed

Garde, Sebastian

2013-01-01

As a basis for semantic interoperability, ideally, a Clinical Knowledge Resource for a clinical concept should be defined formally and defined once in a way that all clinical professions and all countries can agree on. Clinical Knowledge Governance is required to create high-quality, reusable Clinical Knowledge Resources and achieve this aim. Traditionally, this is a time-consuming and cumbersome process, relying heavily on face-to-face meetings and being able to get sufficient input from clinicians. However, in a national or even international space, it is required to streamline the processes involved in creating Clinical Knowledge Resources. For this, a Web 2.0 tool that supports online collaboration of clinicians during their creation and publishing of Clinical Knowledge Resources has been developed. This tool is named the Clinical Knowledge Manager (CKM) and supports the development, review and publication of Clinical Knowledge Resources. Also, post-publication activities such as adding terminology bindings, translating the Clinical Knowledge Resource into another language and republishing it are supported. The acceptance of Clinical Knowledge Resources depends on their quality and being able to determine their quality, for example it is important to know that a broad umber of reviewers from various clinical disciplines have been involved in the development of the Clinical Knowledge Resource. We are still far from realizing the vision of a global repository of a great number of reusable, high-quality Clinical Knowledge Resources, which can provide the basis for broad semantic interoperability between systems. However progress towards this aim is being made around the world.

Lopes, Lucas; Gato, Jorge; Esteves, Manuel

2016-11-01

Lesbian, gay, bisexual and transgender people still face discrimination in healthcare environments and physicians often report lack of knowledge on this population's specific healthcare needs. In fact, recommendations have been put forward to include lesbian, gay, bisexual and transgender health in medical curricula. This study aimed to explore factors associated with medical students' knowledge and attitudes towards homosexuality in different years of the medical course. An anonymous online-based questionnaire was sent to all medical students enrolled at the Faculty of Medicine - University of Porto, Portugal, in December 2015. The questionnaire included socio-demographic questions, the Multidimensional Scale of Attitudes Toward Lesbians and Gay Men (27 items) and a Homosexuality Knowledge Questionnaire (17 items). Descriptive statistics, ANOVAs, Chi-square tests and Pearson's correlations were used in the analysis. A total of 489 completed responses was analyzed. Male gender, religiosity and absence of lesbian, gay or bisexual friends were associated with more negative attitudes towards homosexuality. Attitudinal scores did not correlate with advanced years in medical course or contact with lesbian, gay or bisexual patients. Students aiming to pursue technique-oriented specialties presented higher scores in the 'Modern Heterosexism' subscale than students seeking patient-oriented specialties. Although advanced years in medical course correlated significantly with higher knowledge scores, items related with lesbian, gay or bisexual health showed the lowest percentage of correct answers. There seems to be a lack of exploration of medical students' personal attitudes towards lesbians and gay men, and also a lack of knowledge on lesbian, gay or bisexual specific healthcare needs. This study highlights the importance of inclusive undergraduate curriculum development in order to foster quality healthcare.

Rethinking knowledge and pedagogy in dental education.

PubMed

Whipp, J L; Ferguson, D J; Wells, L M; Iacopino, A M

2000-12-01

Dentistry as a profession has often been considered both art and science. Traditional dental education has attempted to address both; however, in many places only the science of dentistry is emphasized. The move toward competency-based curricula in dental education requires an expansion of what constitutes meaningful knowledge in the curriculum and what pedagogies best support that curriculum. The scientific and technical knowledge considered foundational to clinical practice is not sufficient to teach competencies associated with the art of dentistry. Habermas, a social scientist, offers a way of looking beyond technical knowledge to consider two other forms of knowledge: practical and emancipatory. Pedagogy that supports development of practical and emancipatory knowledge includes problem-based learning and case methods, heuristics, reflective practica, journals, storytelling, and performance-based assessment methods. These important teaching strategies are being integrated into various dental curricula including a new competency-based dental curriculum at Marquette University's School of Dentistry. It will be critical for dental educators to continue developing these methods to provide efficient and effective education for future practitioners in both the art and science of dentistry.

Background: Safe drinking water is essential for well-being. Although microbiological contamination remains the largest cause of water-related morbidity and mortality globally, chemicals in water supplies may also cause disease, and evidence of the human health consequences is limited or lacking for many of them. Objectives: We aimed to summarize the state of knowledge, identify gaps in understanding, and provide recommendations for epidemiological research relating to chemicals occurring in drinking water. Discussion: Assessing exposure and the health consequences of chemicals in drinking water is challenging. Exposures are typically at low concentrations, measurements in water are frequently insufficient, chemicals are present in mixtures, exposure periods are usually long, multiple exposure routes may be involved, and valid biomarkers reflecting the relevant exposure period are scarce. In addition, the magnitude of the relative risks tends to be small. Conclusions: Research should include well-designed epidemiological studies covering regions with contrasting contaminant levels and sufficient sample size; comprehensive evaluation of contaminant occurrence in combination with bioassays integrating the effect of complex mixtures; sufficient numbers of measurements in water to evaluate geographical and temporal variability; detailed information on personal habits resulting in exposure (e.g., ingestion, showering, swimming, diet); collection of biological samples to measure relevant biomarkers; and advanced statistical models to estimate exposure and relative risks, considering methods to address measurement error. Last, the incorporation of molecular markers of early biological effects and genetic susceptibility is essential to understand the mechanisms of action. There is a particular knowledge gap and need to evaluate human exposure and the risks of a wide range of emerging contaminants.

Quantification is Neither Necessary Nor Sufficient for Measurement

Mari, Luca; Maul, Andrew; Torres Irribarra, David; Wilson, Mark

2013-09-01

Being an infrastructural, widespread activity, measurement is laden with stereotypes. Some of these concern the role of measurement in the relation between quality and quantity. In particular, it is sometimes argued or assumed that quantification is necessary for measurement; it is also sometimes argued or assumed that quantification is sufficient for or synonymous with measurement. To assess the validity of these positions the concepts of measurement and quantitative evaluation should be independently defined and their relationship analyzed. We contend that the defining characteristic of measurement should be the structure of the process, not a feature of its results. Under this perspective, quantitative evaluation is neither sufficient nor necessary for measurement.

University science students' knowledge of fats.

PubMed

Mazier, M J Patricia; McLeod, Sheena L

2007-01-01

Students entering university often lack knowledge about fats; whether students gain such information during four years at university is unclear. Students' knowledge of fat in the first and fourth years was measured and compared. The effect of a nutrition course on knowledge was also examined. A total of 215 science students at a small undergraduate university completed a 15-item, closed-ended questionnaire concerning knowledge of fats in the diet. Fourth-year science students have greater nutrition knowledge of fats than do first-year science students (p<0.005). Given that the majority of first-year students reside on campus and the majority of fourth-year students reside off campus, the purchasing of food and preparation of meals may explain the senior students' greater knowledge of fat. Students who have taken a nutrition course know more about fats than do those who have not (p<0.001). Taking even one course in nutrition greatly increases nutrition knowledge. Universities could encourage undergraduate students to take a basic nutrition course, which should emphasize the identification and understanding of different types of dietary fats.

To study the knowledge and practice of physical exercise among the inhabitants of Bangkok. The factors correlated with knowledge and the practice of physical exercise, were also explored. A self-administered questionnaire was designed to survey 1200 inhabitants in Bangkok and the vicinity aged more than 18 years old. One thousand one hundred and seven people aged ranging from 18-81 years old completed the questionnaires (response rate 92.25%). Six hundred and forty people (58.4%) exercised regularly. The exercise was performed 1-2 days per week with varied duration. They performed exercises alone, in their homes, in the evening. They did not report any expenditure on the exercises. Common types of exercise reported were walking, jogging, attending an aerobic exercise class, using an exercise machine, and callisthenic exercise. Two hundred and seven people (18.9%) did not perform exercise at all because of the lack of time. The factors correlated with regular exercise were the increasing age, the high level of education, the amount of free time per day, and the enjoyment of exercise. With relation to knowledge of exercise, most people lacked knowledge of the benefits of exercise rather than how to do exercise and when to stop exercising. People who had a higher educational level than secondary school and a high income, practiced exercise everyday. They acquired their knowledge of exercise from attending an exercise course. People living in Bangkok usually performed regular exercises of 1-2 days per week with varied duration. The majority lacked knowledge of the benefits of exercise. Educational level of the samples was the only factor correlated with both regular exercise and knowledge of exercise.

Background: Electroconvulsive therapy (ECT) is one of the commonly used treatment modalities for patients with severe mental disorders. However, acceptance of ECT by the patient and relatives often depends on how the health-care professionals themselves present the treatment modality to the patients and their relatives. There is a lack of information about the knowledge and attitude toward ECT among health professionals. Aim: This study aimed to evaluate the knowledge about and attitude toward ECT among nursing students. Methodology: Knowledge of and attitudes toward ECT among nursing students were assessed using ECT knowledge and attitude questionnaires. Results: The study included 183 nursing students. Majority (n = 62; 60.8%) of the participants obtained information about ECT from media (movies, television, print media, etc.). None of the students had full knowledge about ECT. Although a significant proportion of students had knowledge about the ECT procedure and consent procedure, majority of them had poor knowledge about the effectiveness, mechanism of action, indications, and side effects of ECT. Negative attitudes were also highly prevalent, with more than two-thirds of the participants having negative attitudes toward ECT on more than half of the attitude items of the scale. Total knowledge score positively correlated with total attitude score, suggesting that higher knowledge was associated with more positive attitude. Conclusions: Although nursing students have knowledge about basic ECT procedure and consent, they lack knowledge about the effectiveness, mechanism of action, indications, and side effects of ECT. Negative attitude toward ECT is also highly prevalent among nursing students. Accordingly, there is a need to improve the knowledge and address the negative attitude of nursing students, which may ultimately lead to better acceptance of the treatment. PMID:28936064

Achievable (ALARA) and budgetary savings. This substitution is referred to as an Acceptable Knowledge Sufficiency Determination. With a Sufficiency Determination Request, AK may supplant the need for one or all of the physical analysis methods. This powerful procedure may be used on a scale as small as a single container to that of a vast waste stream. Only under the most stringent requirements will an AK Sufficiency Determination be approved by the regulators and, to date, only six such Sufficiency Determinations have been approved. Although Acceptable Knowledge is legislated into the operational procedures of the WIPP facility there is more to it than compliance. AK is not merely one of a long list of requirements in the characterization and verification of transuranic (TRU) waste destined for the WIPP. Acceptable Knowledge goes beyond the regulatory threshold by offering a way to reduce risk, cost, time, and uncertainty on its own laurels. Therefore, AK alone can be argued superior to any other waste characterization technique.« less

Perera, Sujan; Henson, Cory; Thirunarayan, Krishnaprasad; Sheth, Amit; Nair, Suhas

2014-03-01

Semantic computing technologies have matured to be applicable to many critical domains such as national security, life sciences, and health care. However, the key to their success is the availability of a rich domain knowledge base. The creation and refinement of domain knowledge bases pose difficult challenges. The existing knowledge bases in the health care domain are rich in taxonomic relationships, but they lack nontaxonomic (domain) relationships. In this paper, we describe a semiautomatic technique for enriching existing domain knowledge bases with causal relationships gleaned from Electronic Medical Records (EMR) data. We determine missing causal relationships between domain concepts by validating domain knowledge against EMR data sources and leveraging semantic-based techniques to derive plausible relationships that can rectify knowledge gaps. Our evaluation demonstrates that semantic techniques can be employed to improve the efficiency of knowledge acquisition.

Nutritional Knowledge and Eating Behaviors of Female, Collegiate Swimmers

PubMed Central

Morris, Jennifer; Morris, Chad; Schaefer, Katharine

2009-01-01

Background Female athletes often have inadequate diets due to lack of nutritional knowledge and nutritional misconceptions. Poor nutrition may lead to an increased chance of developing the Female Athlete Triad, a trio of low energy availability, menstrual dysfunction, and low bone mass. Physical therapists, as part of a healthcare team, must be prepared to address nutritional issues, recognize signs and symptoms of the female athlete triad, and make the appropriate intervention or referral. Objectives The purpose of this study was to determine the nutritional knowledge of female collegiate swimmers and how effectively they apply their nutritional knowledge to their everyday eating habits. Methods Eighty-five female collegiate swimmers from six Michigan universities completed a nutritional knowledge questionnaire and a 24-hour food recall survey. Demographic, nutritional, and statistical data were analyzed. Results The mean score on nutritional knowledge test was 54.53/76 (71.75% correct). Mean total caloric intake of swimmers was 3229.10 calories per day. Ninety-five point nine percent did not meet the recommended dietary allowance (RDA) for all three macronutrients. No difference in total mean survey score existed between the three collegiate divisions. Conclusion This study suggests that athletes lack knowledge of nutrition, healthy food choices, components of a well-balanced diet, and the implications of nutrition on performance. PMID:21509109

Expert knowledge as a foundation for the management of secretive species and their habitat

USGS Publications Warehouse

Drew, C. Ashton; Collazo, Jaime

2012-01-01

In this chapter, we share lessons learned during the elicitation and application of expert knowledge in the form of a belief network model for the habitat of a waterbird, the King Rail (Rallus elegans). A belief network is a statistical framework used to graphically represent and evaluate hypothesized cause and effect relationships among variables. Our model was a pilot project to explore the value of such a model as a tool to help the US Fish and Wildlife Service (USFWS) conserve species that lack sufficient empirical data to guide management decisions. Many factors limit the availability of empirical data that can support landscape-scale conservation planning. Globally, most species simply have not yet been subject to empirical study (Wilson 2000). Even for well-studied species, data are often restricted to specific geographic extents, to particular seasons, or to specific segments of a species’ life history. The USFWS mandates that the agency’s conservation actions (1) be coordinated across regional landscapes, (2) be founded on the best available science (with testable assumptions), and (3) support adaptive management through monitoring and assessment of action outcomes. Given limits on the available data, the concept of “best available science” in the context of conservation planning generally includes a mix of empirical data and expert knowledge (Sullivan et al. 2006).

Avoiding a knowledge gap in a multiethnic statewide social marketing campaign: is cultural tailoring sufficient?

2011-03-01

In 2007, the State of Hawaii, Healthy Hawaii Initiative conducted a statewide social-marketing campaign promoting increased physical activity and nutrition. The campaign included substantial formative research to develop messages tailored for Hawaii's multiethnic Asian and Pacific Islander populations. The authors conducted a statewide random digital dialing telephone survey to assess the campaign's comparative reach among individuals with different ethnicities and different levels of education and income. This analysis suggests that the intervention was successful in reaching its target ethnic audiences. However, a knowledge gap related to the campaign appeared among individuals with incomes less than 130% of the poverty level and those with less than a high school education. These results varied significantly by message and the communication channel used. Recall of supermarket-based messages was significantly higher among individuals below 130% of the poverty level and those between 18 and 35 years of age, 2 groups that showed consistently lower recall of messages in other channels. Results suggest that cultural tailoring for ethnic audiences, although important, is insufficient for reaching low-income populations, and that broad-based social marketing campaigns should consider addressing socioeconomic status-related channel preferences in formative research and campaign design.

Burger, M S; Abraham-Inpijn, L; Vissink, A

2012-03-01

By the nature of his work, a dentist has a higher risk of tuberculosis infection than the average Dutch population. Thus, the question arises whether dentists do have sufficient knowledge on tuberculosis. In order to determine their knowledge, an inventory was conducted among a sample of dentists in the Netherlands. Analysis of the dentists' response to 19 correct or incorrect statements revealed that their knowledge level on tuberculosis was rather low, did not vary with regard to gender, and was independent of the region where they were practising and of their explicit medical interest. The dentists indicated a desire for education on tuberculosis.

Cumulative incidences of completed vocational education, high school education, higher education, time to first full year of economic self-sufficiency, and receipt of disability pension and differences in these outcomes at age 35 years among meningitis patients, comparison cohorts, and siblings. By age 35 years, among persons who had a history of childhood meningococcal (n=1338), pneumococcal (n=455), and H. influenzae (n=991) meningitis, an estimated 11.0% (41.5% vs 52.5%; 95% CI, 7.3%-14.7%), 10.2% (42.6% vs 52.8%; 95% CI, 3.8%-16.6%), and 5.5% (47.7% vs 53.2%; 95% CI, 1.9%-9.1%) fewer persons, respectively, had completed high school and 7.9% (29.3% vs 37.2%; 95% CI, 1.6%-14.2%), 8.9% (28.1% vs 37.0%; 95% CI, 0.6%-17.2%), and 6.5% (33.5% vs 40.0%; 95% CI, 1.4%-11.6%) fewer had attained a higher education compared with individuals from the comparison cohort. Siblings of meningococcal meningitis patients also had lower educational achievements, while educational achievements of siblings of pneumococcal and H. influenzae meningitis patients did not differ substantially from those in the general population. At end of follow-up, 3.8% (90.3% vs 94.1%; 95% CI, 1.1%-6.5%), 10.6% (84.0% vs 94.6%; 95% CI, 5.1%-16.1%), and 4.3% (90.6% vs 94.9%; 95% CI, 2.0%-6.6%) fewer meningococcal, pneumococcal, and H. influenzae meningitis patients

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.

University Students Intend to Eat Better but Lack Coping Self-Efficacy and Knowledge of Dietary Recommendations.

Matthews, June I; Doerr, Lisa; Dworatzek, Paula D N

2016-01-01

To assess university students' knowledge, intentions, and coping self-efficacy related to dietary recommendations. The study used a cross-sectional online survey. Large university campus. Students (n = 6,638; 22% response). Self-efficacy and intentions were measured using 11-point scales. Students' perceived dietary recommendations were evaluated as correct or incorrect. Categorical variables were analyzed using chi-square and continuous variables by t tests or ANOVAs. Significance was set at P ≤ .05 and multiple comparisons at P ≤ .01. Respondents believed that they need fewer vegetables and fruit and more milk or alternatives servings/d than recommended; eg, males aged ≥ 19 years perceived milk or alternatives recommendations to be 4.3 ± 2.1 servings/d, significantly more than the 2 servings/d recommended (P < .001). Students in health sciences or with a food or nutrition course were significantly more likely to claim that they met recommendations (eg, 56% with vs 47% without a food or nutrition course for vegetables and fruit; P < .001); however, they were no more likely to identify them correctly. Males aged < 19 years had higher coping self-efficacy than females aged < 19 years to consume vegetables (68.3 ± 24.2 vs 64.0 ± 24.7; P < .01) and avoid high-calorie foods and beverages (HCFB) (56.2 ± 27.2 vs 49.0 ± 25.2; P < .01) when under stress; however, they had significantly lower intentions to consume vegetables (72.1 ± 24.5 vs 80.9 ± 20.3; P < .01) and avoid HCFB (60.5 ± 30.3 vs 77.7 ± 22.8; P < .01). Students do not have adequate knowledge of age- and sex-specific food guide recommendations. Simpler food guide recommendations or age- and sex-targeted campaigns may enhance knowledge. Students intend to consume more vegetables and less HCFB; however, they have low coping self-efficacy, all of which could be targeted in nutrition interventions.

2017-01-01

Education about virus biology at school is of pivotal interest to raise public awareness concerning means of disease transmission and, thus, methods to prevent infection, and to reduce unnecessary antibiotic treatment due to patient pressure on physicians in case of viral diseases such as influenza. This study aimed at making visible the knowledge of Austrian high school and university students with respect to virus biology, virus structure and health-education issues. The data presented here stem from comprehensive questionnaire analyses, including the task to draw a virus, from a cross-sectional study with 133 grade 7 and 199 grade 10 high school students, and 133 first-year biology and 181 first-year non-biology university students. Analyses were performed both quantitatively and qualitatively. ANOVA revealed a highly significant group effect for total knowledge relating to virus biology and health issues (F(3, 642) = 44.17, p < 0.01, η2p = 0.17). Specific post-hoc tests by means of the Tukey test showed significant differences between all groups (p < .01) with the exception of 1st year non-biology students and grade 10 high school students. Students enrolled in university-level biology outperformed all other groups, even though they had not yet encountered this topic at their courses; part of this phenomenon might be due to their affinity for learning about biological topics. However, even many first-year biology students had a high number of severe misconceptions, e.g., defining a virus as a pro- or eukaryotic cell, or falsely naming malaria as a viral disease. Since there was no significant difference in virus-related knowledge between high schools, virus biology seems to have been taught similarly among the tested schools. However, the majority of participants stated that the virus-related knowledge they had acquired at school was not sufficient. Based on the results presented here we urgently suggest improving and intensifying teaching this topic at school

2017-12-01

This study was meant to be the first step in bridging a gap in the literature concerning Puerto Rican geriatric patients' levels of knowledge concerning 4 preventive care screening tests: mammography, bone densitometry, colonoscopy, and lipid panels. Patients 65 years old and older were interviewed at the University of Puerto Rico (UPR), Medical Sciences Campus, primary care clinics. Fisher's exact test was used to assess knowledge status for each screening test. Fifty-three participants, 53% being women, took part in the study. All the women (100%) reported having knowledge about mammography screening as well as about bone densitometry scans (71%); 91% of the participants reported having knowledge concerning colonoscopy. Only 34% understood what information results from a lipid panel. The majority of the participants were not aware of precisely when each of the screening tests under discussion should be undertaken. For all the screenings, level of education and provider recommendation were associated with increased levels of knowledge (though statistically significant only for bone densitometry and lipid panels). Elderly Puerto Ricans appear to have knowledge about screening tests; however, there is an overall lack of knowledge about the timing of screening. Risk factors for this lack of knowledge are having a relatively lower level of education, the lack of healthcare-provider recommendation, and the lack of patient education. Understanding when to have tests is vital for interventions, in order to improve patient outcomes, which can include death from treatable conditions or diseases. Future research should include larger samples as well as studies of outcomes associated with these screening tests. These will help researchers and policymakers better understand this issue and aid in the development and implementation of interventions for both patients and physicians.

Lack of knowledge about iodine may be a risk factor for iodine deficiency in pregnant and lactating women. The aim of this study was to assess knowledge about iodine and predictors of iodine knowledge scores among pregnant and lactating women. The study also examined whether iodine knowledge scores were associated with iodine status. A cross-sectional study was performed on 804 pregnant women and 175 lactating women from 18 to 44 years of age in 2016 in the Oslo area, Norway. Knowledge about iodine was collected through a self-administered, paper-based questionnaire. Iodine concentrations in urine and breast milk were measured using an inductively coupled plasma mass spectrometer (ICPMS). 74% of the pregnant women and 55% of the lactating women achieved none to low iodine knowledge scores. Higher educated pregnant women and those who had received information about iodine had significantly higher knowledge scores. In lactating women, increased age was associated with higher knowledge scores. Knowledge scores were not associated with participants' iodine status. This study revealed a lack of knowledge about the importance of iodine in pregnant and lactating women, as well as about the most important dietary sources. Public education initiatives are required to increase the awareness about iodine in these population groups.

Knowledge about cervical cancer (CC) risk factors and benefits of CC prevention motivates women to participate in its screening. However, several studies show that there is a significant knowledge deficit worldwide about human papillomavirus (HPV). The current study explores the level of knowledge about HPV and CC prevention in the context of sociodemographic and behavioral characteristics of women who visited an antenatal clinic in Arkhangelsk, Russia. This cross-sectional study was conducted in the city of Arkhangelsk, which seats the administrative center of Arkhangelsk County, Northwest Russia. It included women who consulted a gynecologist for any reason between January 1, 2015 and April 30, 2015, were residents of Arkhangelsk, 25 to 65 years of age and sexually active (N = 300). Student's t-test for continuous variables and Pearson's χ2 test for categorical variables were used in the comparisons of women grouped as having either poor or sufficient knowledge. Linear regression analysis was also employed. The level of knowledge about HPV and CC prevention was associated with education, parity, age of initiating of intercourse, and sources of information. After adjustment, women with university education were more likely to have higher knowledge about HPV and CC prevention compared to those with lower education. We observed that most participants had a sufficient level of knowledge. Educational gaps were identified that potentially could be used to tailor interventions in CC prevention.

Predictive sufficiency and the use of stored internal state

Musliner, David J.; Durfee, Edmund H.; Shin, Kang G.

In all embedded computing systems, some delay exists between sensing and acting. By choosing an action based on sensed data, a system is essentially predicting that there will be no significant changes in the world during this delay. However, the dynamic and uncertain nature of the real world can make these predictions incorrect, and thus, a system may execute inappropriate actions. Making systems more reactive by decreasing the gap between sensing and action leaves less time for predictions to err, but still provides no principled assurance that they will be correct. Using the concept of predictive sufficiency described in this paper, a system can prove that its predictions are valid, and that it will never execute inappropriate actions. In the context of our CIRCA system, we also show how predictive sufficiency allows a system to guarantee worst-case response times to changes in its environment. Using predictive sufficiency, CIRCA is able to build real-time reactive control plans which provide a sound basis for performance guarantees that are unavailable with other reactive systems.

Nurses now require a basic knowledge of genetics to provide patient care in a range of settings. To determine Turkish registered nurses' current knowledge and educational needs in relation to genetics. A descriptive, cross-sectional study. Turkish registered nurses working in a university hospital in Turkey were recruited. All registered nurses were invited to participate and 175 completed the study. The survey instrument, basic knowledge of health genetics, confidence in knowledge and the nurses' need for genetics education were used to collect data. The majority (81.1%, n=142) of participants indicated that genetics was not taught during their degree program, although 53.1% to 96% of respondents felt confident in defining different genetic concepts. The average genetics knowledge score was 6.89±1.99 of a possible 11 (range 0-11). The majority (70.3%) expressed a strong wish to attend a continuing nursing education program in genetics. The study shows that although Turkish nurses are not sufficiently knowledgeable to apply genetics in practice, they are willing to have more education to support their care of patients. Nurses need to have more education related to genetics in accordance with advances in human genetics to optimize health care. Copyright © 2014 Elsevier Ltd. All rights reserved.

Lack of relevant information for tumor staging in pathology reports of primary cutaneous melanoma.

PubMed

Busam, K J

2001-05-01

For the T classification of primary cutaneous melanoma, the current American Joint Committee on Cancer staging (AJCC) system relies on tumor thickness and level of invasion. A new T classification has been proposed based on thickness and ulceration. The slides and reports of 135 departmental pathology consultations of patients referred to a major cancer center with a diagnosis of primary cutaneous invasive malignant melanoma were examined. Whether the outside pathology reports contained information on tumor thickness, level of invasion, and ulceration was recorded. Dermatopathologists had issued 76.3% of the reports and general surgical pathologists, 24.3%. Information provided was as follows: tumor thickness, 97.8%; Clark level, 71.9%; and presence or absence of ulceration, 28.1%. Of the 97 melanomas with no comment on ulceration, 17 were indeed ulcerated. Thus, the lack of a comment on ulceration cannot be equated with the absence of ulceration. The present study documents that many pathology reports on melanomas lack sufficient information for AJCC staging. Therefore, review of outside pathology material is necessary not only to confirm or revise the tumor diagnosis but also to provide clinicians with histologic parameters required for AJCC staging.

Clinicians cite parental misconceptions and requests for antibiotics as reasons for inappropriate prescribing. To identify misconceptions regarding antibiotics and predictors of parental demand for antibiotics and to determine if parental knowledge and attitudes are associated with use. Survey of parents in 16 Massachusetts communities. Domains included antibiotic-related knowledge, attitudes about antibiotics, antibiotic use during a 12-month period, demographics, and access to health information. Bivariate and multivariate analyses evaluated predictors of knowledge and proclivity to demand antibiotics. A multivariate model evaluated the associations of knowledge, demand, and demographic factors with parent-reported antibiotic use. A total of 1106 surveys were returned (response rates: 54% and 32% for commercially-insured and Medicaid-insured families). Misconceptions were common regarding bronchitis (92%) and green nasal discharge (78%). Two hundred sixty-five (24%) gave responses suggesting a proclivity to demand antibiotics. Antibiotic knowledge was associated with increased parental age and education, having more than 1 child, white race, and receipt of media information on resistance. Factors associated with a proclivity to demand antibiotics included decreased knowledge, pressure from day-care settings, lack of alternatives offered by clinicians, and lack of access to media information. Among all respondents, reported antibiotic use was associated with younger child age and day-care attendance. Among Medicaid-insured children only, less antibiotic knowledge and tendency to demand antibiotics were associated with higher rates of antibiotic use. Misconceptions regarding antibiotic use are widespread and potentially modifiable by clinicians and media sources. Particular attention should be paid to Medicaid-insured patients in whom such misconceptions may contribute to inappropriate prescribing.

How far we are from the complete knowledge: Complexity of knowledge acquisition in Dempster-Shafer approach

NASA Technical Reports Server (NTRS)

Chokr, Bassam A.; Kreinovich, Vladik YA.

1991-01-01

When a knowledge base represents the experts' uncertainty, then it is reasonable to ask how far we are from the complete knowledge, that is, how many more questions do we have to ask (to these experts, to nature by means of experimenting, etc) in order to attain the complete knowledge. Of course, since we do not know what the real world is, we cannot get the precise number of questions from the very beginning: it is quite possible, for example, that we ask the right question first and thus guess the real state of the world after the first question. So we have to estimate this number and use this estimate as a natural measure of completeness for a given knowledge base. We give such estimates for Dempster-Shafer formalism. Namely, we show that this average number of questions can be obtained by solving a simple mathematical optimization problem. In principle this characteristic is not always sufficient to express the fact that sometimes we have more knowledge. For example, it has the same value if we have an event with two possible outcomes and nothing else is known, and if there is an additional knowledge that the probability of every outcome is 0.5. We'll show that from the practical viewpoint this is not a problem, because the difference between the necessary number of questions in both cases is practically negligible.

Shark Conservation: An Educational Approach Based on Children's Knowledge and Perceptions toward Sharks.

PubMed

Tsoi, Kwok Ho; Chan, Sau Ying; Lee, Yeung Chung; Ip, Brian Ho Yeung; Cheang, Chi Chiu

Shark conservation has become a focus of current international conservation efforts. However, the misunderstanding of sharks and their negative public portrayal may hinder their conservation. More importantly, the consumption of shark fin, which is very common in Chinese cultures, poses a significant threat to sharks. Hong Kong has long been the world's largest shark fin trading center. Shark conservation would become more sustainable if public understanding of this predatory fish and an appreciation of its ecological significance could be promoted. It is possible that the demand for fins could be effectively managed through long-term educational efforts targeted at younger generations. To provide essential baseline data for planning of these educational efforts, this project investigated the perceptions of 11 to 12 year-old primary school students in Hong Kong about sharks, and their understanding of ecological concepts and shark-related knowledge. The findings indicate that these students lack sufficient knowledge and possess misconceptions about sharks and their ecological significance in the marine ecosystem. The students' conceptual understanding level is strongly correlated with their perceptions. Correlational analyses further demonstrated a positive association between formal education and perceptions toward shark conservation. The students who favoured shark fin consumption did so because of its tastiness, whereas concerns about shark population decline and the cruelty of shark hunting were the main reasons for not favoring shark fin consumption. This pilot study provides preliminary but important insights into primary school education regarding the conservation of sharks.

1997-11-01

The goals of the present study were to examine the extent of children's religious, especially satanic, knowledge and to understand the influence of children's age, religious training, family, and media exposure on that knowledge. Using a structured interview, 48 3- to 16-year-old children were questioned about their knowledge of: (a) religion and religious worship; (b) religion-related symbols and pictures; and (c) movies, music, and television shows with religious and horror themes. Although few children evinced direct knowledge of ritual abuse, many revealed general knowledge of satanism and satanic worship. With age, children's religious knowledge increased and became more sophisticated. Increased exposure to nonsatanic horror media was associated with more nonreligious knowledge that could be considered precursory to satanic knowledge, and increased exposure to satanic media was associated with more knowledge related to satanism. Our results suggest that children do not generally possess sufficient knowledge of satanic ritual abuse to make up false allegations on their own. However, many children have knowledge of satanism as well as nonreligious knowledge of violence, death, and illegal activities. It is possible that such knowledge could prompt an investigation of satanic ritual abuse or possibly serve as a starting point from which an allegation is erected.

Nurses are the majority of health-care professionals who frequently come in contact with people living with HIV/AIDS (PLWHA). However, most health workers such as nurses lack competence and confidence in dealing with the mental health problems (MHPs) of their clients in Malawi. The study aimed at exploring nurses' levels of knowledge and skills in providing mental health care to PLWHA. The study used a descriptive quantitative survey design. Ethical approval and permission were granted by relevant authorities to conduct the study. A convenient sample of 109 nurses was used. They gave written consent and completed self-administered questionnaires. Descriptive statistics namely: means, frequencies and percentages were used to analyse data. The findings suggest that nurses who care for PLWHA lack knowledge and skills to deal with MHPs of these people. Many participants (53.2%, n = 58) lacked knowledge and skills to care for PLWHA who have MHPs. Nurses are potentially essential human resource for dealing with MHPs of PLWHA in Malawi. Unfortunately, some nurses lack the necessary knowledge and skills to deal with MHPs. Nurses must be equipped with adequate knowledge and skills so that they are able to deal with MHPs of PLWHA. © 2013 John Wiley & Sons Ltd.

2016-01-01

Context: Nutrition knowledge can influence dietary choices and impact on athletic performance. Valid and reliable measures are needed to assess the nutrition knowledge of athletes and coaches. Objectives: (1) To systematically review the published literature on nutrition knowledge of adult athletes and coaches and (2) to assess the quality of measures used to assess nutrition knowledge. Data Sources: MEDLINE, CINAHL, SPORTDiscuss, Web of Science, and SCOPUS. Study Selection: 36 studies that provided a quantitative measure of nutrition knowledge and described the measurement tool that was used were included. Data extraction: Participant description, questionnaire description, results (mean correct and responses to individual items), study quality, and questionnaire quality. Data synthesis: All studies were of neutral quality. Tools used to measure knowledge did not consider health literacy, were outdated with regards to consensus recommendations, and lacked appropriate and adequate validation. The current status of nutrition knowledge in athletes and coaches is difficult to ascertain. Gaps in knowledge also remain unclear, but it is likely that energy density, the need for supplementation, and the role of protein are frequently misunderstood. Conclusions: Previous reports of nutrition knowledge need to be interpreted with caution. A new, universal, up-to-date, validated measure of general and sports nutrition knowledge is required to allow for assessment of nutrition knowledge. PMID:27649242

Federal attempts to stimulate technological innovation have been unsuccessful because of the application of an inappropriate policy framework that lacks conceptual and empirical knowledge of the process of technological innovation and fails to acknowledge the relationship between knowledge production, transfer, and use as equally important components of the process of knowledge diffusion. This article argues that the potential contributions of high-speed computing and networking systems will be diminished unless empirically derived knowledge about the information-seeking behavior of members of the social system is incorporated into a new policy framework. Findings from the NASA/DoD Aerospace Knowledge Diffusion Research Project are presented in support of this assertion.

Knowledge-based systems are modeled as deductive systems. The model indicates that the two primary areas of concern in verification are demonstrating consistency and completeness. A system is inconsistent if it asserts something that is not true of the modeled domain. A system is incomplete if it lacks deductive capability. Two forms of consistency are discussed along with appropriate verification methods. Three forms of incompleteness are discussed. The use of metaknowledge, knowledge about knowledge, is explored in connection to each form of incompleteness.

Professionals working in the multidisciplinary field of eHealth vary in their educational background. However, knowledge in the areas of medicine, engineering and management is required to fulfil the tasks associated with eHealth sufficiently. Based on the results of an analysis of national and international educational offers a survey gathering user requirements for the development of knowledge profiles in eHealth was conducted (n=75) by professionals and students. During a workshop the first results were presented and discussed together with the network partners and the attendees. The resulting knowledge profiles contain knowledge areas of all three thematic content categories including fundamentals of medical terminology, standards and interoperability and usability as well as basics of all three content categories. The knowledge profiles are currently applied in a master's degree programme at the UAS Technikum Wien and will be developed further.

Biomedical waste management has become a concern with increasing number of dental practitioners in India. Being health care professionals, dentists should be aware regarding safe disposal of biomedical waste and recycling of dental materials to minimize biohazards to the environment. The aim of the present study was to assess awareness regarding biomedical waste management as well as knowledge of effective recycling and reuse of dental materials among dental students. This cross-sectional study was conducted among dental students belonging from all dental colleges of Bhubaneswar, Odisha (India) from February 2016 to April 2016. A total of 500 students (208 males and 292 females) participated in the study, which was conducted in two phases. A questionnaire was distributed to assess the awareness of biomedical waste management and knowledge of effective recycling of dental materials, and collected data was examined on a 5-point unipolar scale in percentages to assess the relative awareness regarding these two different categorizes. The Statistical Package for Social Sciences was used to analyzed collected data. Forty-four percent of the dental students were not at all aware about the management of biomedical waste, 22% were moderately aware, 21% slightly aware, 7% very aware, and 5% fell in extremely aware category. Similarly, a higher percentage of participants (61%) were completely unaware regarding recycling and reusing of biomedical waste. There is lack of sufficient knowledge among dental students regarding management of biomedical waste and recycling or reusing of dental materials. Considering its impact on the environment, biomedical waste management requires immediate academic assessment to increase the awareness during training courses.

Errors in drug dosing lead to poor patient outcomes and are common in patients with chronic kidney disease (CKD). Because the majority of patients with CKD are being treated by physicians specializing in internal medicine, we studied the awareness and knowledge that internal medicine resident trainees (IMRTs) have regarding the correct dosage of commonly used analgesic and neuropsychotropic medications for patients with CKD. We surveyed 353 IMRTs about their awareness of whether a medication needs dose adjustment in patients with CKD and knowledge for medication adjustment by level of glomerular filtration rate. There were high percentages for lack of awareness and knowledge. For analgesics, this lack of awareness/knowledge was highest for acetaminophen (awareness 83.0%, knowledge 90.9%). For neuropsychotropics, this was highest for paroxetine (awareness 74.5%, knowledge 91.5%). Analyses for postgraduate year (PGY) -1 trainees and PGY-2 trainees for analgesics showed higher odds for lack of awareness for tramadol (PGY-1 odds ratio [OR] 2.37, 95% confidence interval [CI] 1.2-4.62, P < 0.05; PGY-2 OR 2.34, 95% CI 1.16-4.72, P < 0.05) and for lack of knowledge for meperedine (PGY-1 OR 4.01, 95% CI 1.81-8.89, P < 0.05; PGY-2 OR 3.30, 95% CI 1.44-7.59, P < 0.05). Nephrology residency rotation for the neuropsychotropic medication of gabapentin showed lower odds for both lack of awareness (OR 0.56, 95% CI 0.32-0.97, P < 0.05) and knowledge (OR 0.52, 95% CI 0.27-0.997, P < 0.05). Awareness and knowledge are poor among IMRTs for dose adjustments of analgesics and neuropsychotropic medication classes in patients with CKD. There should be a renewed focus during IMRTs' residency on additional nephrology exposure and formal didactic educational training to help them better manage complex treatment regimens to prevent medication dosing errors.

The problem of superposition of two corresponding vector sets by minimizing their sum-of-squares error under orthogonal transformation is a fundamental task in many areas of science, notably structural molecular biology. This problem can be solved exactly using an algorithm whose time complexity grows linearly with the number of correspondences. This efficient solution has facilitated the widespread use of the superposition task, particularly in studies involving macromolecular structures. This article formally derives a set of sufficient statistics for the least-squares superposition problem. These statistics are additive. This permits a highly efficient (constant time) computation of superpositions (and sufficient statistics) of vector sets that are composed from its constituent vector sets under addition or deletion operation, where the sufficient statistics of the constituent sets are already known (that is, the constituent vector sets have been previously superposed). This results in a drastic improvement in the run time of the methods that commonly superpose vector sets under addition or deletion operations, where previously these operations were carried out ab initio (ignoring the sufficient statistics). We experimentally demonstrate the improvement our work offers in the context of protein structural alignment programs that assemble a reliable structural alignment from well-fitting (substructural) fragment pairs.

There are millions of individuals living in North America and the European Union who lack access to healthcare services. When these individuals participate in research, they are at increased risk of being exposed to the risks and burdens of clinical trials without realizing the benefits that result from them. The mechanisms that have been proposed to ensure that research participants in low‐ and middle‐income countries are not exploited are unlikely to protect participants in high‐income countries. The present manuscript argues that one way to address concerns about exploitation in high‐income countries would be to require sponsors to provide targeted benefits such as medical treatment during the trial, or the study drug after the trial. The latter could be achieved through extension studies, expanded access programs, or named‐patient programs. Sponsors also might provide non‐medical benefits, such as education or social support. Ethical and regulatory guidance should be revised to ensure that research participants in high‐income countries who lack access to healthcare services receive sufficient benefits. PMID:26743927

Cytochrome P450 monooxygenases (CYPs) are useful catalysts for oxidation reactions. Self-sufficient CYPs harbour a reductive domain covalently connected to a P450 domain and are known for their robust catalytic activity with great potential as biocatalysts. In an effort to expand genetic sources of self-sufficient CYPs, we devised a sequence-based screening system to identify them in a soil metagenome. We constructed a soil metagenome library and performed sequence-based screening for self-sufficient CYP genes. A new CYP gene, syk181, was identified from the metagenome library. Phylogenetic analysis revealed that SYK181 formed a distinct phylogenic line with 46% amino-acid-sequence identity to CYP102A1 which has been extensively studied as a fatty acid hydroxylase. The heterologously expressed SYK181 showed significant hydroxylase activity towards naphthalene and phenanthrene as well as towards fatty acids. Sequence-based screening of metagenome libraries is expected to be a useful approach for searching self-sufficient CYP genes. The translated product of syk181 shows self-sufficient hydroxylase activity towards fatty acids and aromatic compounds. SYK181 is the first self-sufficient CYP obtained directly from a metagenome library. The genetic and biochemical information on SYK181 are expected to be helpful for engineering self-sufficient CYPs with broader catalytic activities towards various substrates, which would be useful for bioconversion of natural products and biodegradation of organic chemicals.

Donor recruitment and retention are significant problems in blood collection agencies around the world. The Aim of this study was to determine the causes of lack of interest to blood donation in eligible individu-als in Mashhad, Northeast of Iran. This was a descriptive study. Cases were 1130 non-donor individuals. Participants were selected from eligible individuals in different regions of Mashhad. In this study, surveys included information about age groups, gender, residence area, marriage, education; living situation and job as background variables. Less than 30% of the cases had enough knowledge about blood donation. There was a significant rela-tionship between location, age, education, occupation and social status with knowledge of blood donation, but there was not a correlation between gender and marital status. There are some factors which affect the decision for blood donation. There is a need to change the negative attitude by increasing the knowledge considering the individual and the social status.

Two synaptobrevin molecules are sufficient for vesicle fusion in central nervous system synapses

PubMed Central

Sinha, Raunak; Ahmed, Saheeb; Jahn, Reinhard; Klingauf, Jurgen

2011-01-01

Exocytosis of synaptic vesicles (SVs) during fast synaptic transmission is mediated by soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) complex assembly formed by the coil-coiling of three members of this protein family: vesicle SNARE protein, synaptobrevin 2 (syb2), and the presynaptic membrane SNAREs syntaxin-1A and SNAP-25. However, it is controversially debated how many SNARE complexes are minimally needed for SV priming and fusion. To quantify this effective number, we measured the fluorescence responses from single fusing vesicles expressing pHluorin (pHl), a pH-sensitive variant of GFP, fused to the luminal domain of the vesicular SNARE syb2 (spH) in cultured hippocampal neurons lacking endogenous syb2. Fluorescence responses were quantal, with the unitary signals precisely corresponding to single pHluorin molecules. Using this approach we found that two copies of spH per SV fully rescued evoked fusion whereas SVs expressing only one spH were unable to rapidly fuse upon stimulation. Thus, two syb2 molecules and likely two SNARE complexes are necessary and sufficient for SV fusion during fast synaptic transmission. PMID:21844343

Shark Conservation: An Educational Approach Based on Children’s Knowledge and Perceptions toward Sharks

Shark conservation has become a focus of current international conservation efforts. However, the misunderstanding of sharks and their negative public portrayal may hinder their conservation. More importantly, the consumption of shark fin, which is very common in Chinese cultures, poses a significant threat to sharks. Hong Kong has long been the world’s largest shark fin trading center. Shark conservation would become more sustainable if public understanding of this predatory fish and an appreciation of its ecological significance could be promoted. It is possible that the demand for fins could be effectively managed through long-term educational efforts targeted at younger generations. To provide essential baseline data for planning of these educational efforts, this project investigated the perceptions of 11 to 12 year-old primary school students in Hong Kong about sharks, and their understanding of ecological concepts and shark-related knowledge. The findings indicate that these students lack sufficient knowledge and possess misconceptions about sharks and their ecological significance in the marine ecosystem. The students’ conceptual understanding level is strongly correlated with their perceptions. Correlational analyses further demonstrated a positive association between formal education and perceptions toward shark conservation. The students who favoured shark fin consumption did so because of its tastiness, whereas concerns about shark population decline and the cruelty of shark hunting were the main reasons for not favoring shark fin consumption. This pilot study provides preliminary but important insights into primary school education regarding the conservation of sharks. PMID:27684706

A Framework for Creating a Function-based Design Tool for Failure Mode Identification

Arunajadai, Srikesh G.; Stone, Robert B.; Tumer, Irem Y.; Clancy, Daniel (Technical Monitor)

2002-01-01

Knowledge of potential failure modes during design is critical for prevention of failures. Currently industries use procedures such as Failure Modes and Effects Analysis (FMEA), Fault Tree analysis, or Failure Modes, Effects and Criticality analysis (FMECA), as well as knowledge and experience, to determine potential failure modes. When new products are being developed there is often a lack of sufficient knowledge of potential failure mode and/or a lack of sufficient experience to identify all failure modes. This gives rise to a situation in which engineers are unable to extract maximum benefits from the above procedures. This work describes a function-based failure identification methodology, which would act as a storehouse of information and experience, providing useful information about the potential failure modes for the design under consideration, as well as enhancing the usefulness of procedures like FMEA. As an example, the method is applied to fifteen products and the benefits are illustrated.

Cancer and its treatments may result in impaired fertility, which could cause long-term distress to cancer survivors. For eligible patients, fertility preservation (FP) is available to secure future reproductive potential. Many physicians, however, feel inhibited about discussing FP. Oncology nurses may serve as an initiator for discussing the subject and provide additional support. Our aim was to investigate their knowledge about FP, the way they apply this, and possible barriers to discussing FP with patients of reproductive age. A questionnaire was administered via mail, Internet and the Dutch Oncology Nursing Congress. Four hundred and twenty-one oncology nurses participated, a third of whom (31.1%) had "sufficient" knowledge of FP. Twenty-eight per cent of participants reported that they "never/hardly ever" discussed FP; 32.2% "almost always/always." FP discussions were more frequently performed by graduate nurses, academic nurses, experienced nurses and nurses with sufficient knowledge. Reasons for not discussing FP were a "lack of knowledge" (25.2%), "poor prognosis" (16.4%) and "lack of time" (10.5%). In conclusion, several obstacles may result in FP not being routinely discussed, specifically a lack of knowledge. Yet nurses feel responsible for addressing the issue, indicating that assistance with FP discussions should be encouraged. Educational training about FP is recommended. © 2016 John Wiley & Sons Ltd.

Sufficient Dimension Reduction for Longitudinally Measured Predictors

Pfeiffer, Ruth M.; Forzani, Liliana; Bura, Efstathia

2013-01-01

We propose a method to combine several predictors (markers) that are measured repeatedly over time into a composite marker score without assuming a model and only requiring a mild condition on the predictor distribution. Assuming that the first and second moments of the predictors can be decomposed into a time and a marker component via a Kronecker product structure, that accommodates the longitudinal nature of the predictors, we develop first moment sufficient dimension reduction techniques to replace the original markers with linear transformations that contain sufficient information for the regression of the predictors on the outcome. These linear combinations can then be combined into a score that has better predictive performance than the score built under a general model that ignores the longitudinal structure of the data. Our methods can be applied to either continuous or categorical outcome measures. In simulations we focus on binary outcomes and show that our method outperforms existing alternatives using the AUC, the area under the receiver-operator characteristics (ROC) curve, as a summary measure of the discriminatory ability of a single continuous diagnostic marker for binary disease outcomes.

Scientific research not only promotes health and combats diseases of an individual, but also it can strengthen the effectiveness of health systems. Hence, understanding of scientific methods becomes a crucial component in the medical profession. This study was conducted to assess the knowledge, attitudes, and barriers toward research among undergraduate medical and dental students. This cross-sectional study was conducted among 295 undergraduate Bachelor of Medicine and Bachelor of Surgery (MBBS) and Bachelor of Dental Surgery (BDS) students from a private medical college in Malaysia. We purposively selected 360 students attending the 3 rd , 4 th , and 5 th year in MBBS course and BDS course in September 2015. A total of 295 students who were willing to provide written informed consent were included in this study. We collected data using a validated, self-administered, structured questionnaire which included 20 questions about knowledge toward scientific research, 21 attitude items in regard to scientific research, a list of 10 barriers toward conducting medical research, and 5 questions of confidence to conduct the medical research. Data were analyzed using descriptive statistics, independent t-test, ANOVA, and multiple linear regression. Among the students, 56.9% had moderate knowledge while the majority (83.3%) had moderate attitude toward scientific research. The majorly cited barriers were the lack of time (79.9%), lack of knowledge and skills (72.1%), lack of funding (72.0%) and facilities (63.6%), and lack of rewards (55.8%). There was a significant association between age, academic year, and knowledge of research as the older age group, and 4 th - and 5 th -year students had higher knowledge score. The students of higher attitude score had better-perceived barriers score toward research with regression coefficient 0.095 (95% confidence interval 0.032-0.159). Even though the students had the positive attitudes toward scientific research, a supportive and

Genetics is one of the topics or subject matter in biology that are considered difficult. Student difficulties of understanding genetics, can be caused by lack of understanding this concept and the way of teachers teach. Pedagogical Content Knowledge (PCK) is a way to understand the complex relationships between teaching and content taught through the use of specific teaching approaches. The aims of study was to analyze genetic PCK ability profile of prospective biology teacher.13 student of sixth semester Biology education department who learned Kapita Selekta Biologi SMA course, participated in this study. PCK development was measured by CoRes (Content Representation). Before students fill CoRes, students are tested mastery genetic concepts through a multiple-choice test with three tier-test. Data was obtained from the prior CoRes and its revisions, as well as the mastery concept in pre and post test. Results showed that pre-test of genetic mastery concepts average on 55.4% (low category) and beginning of the writing CoRes, student get 43.2% (Pra PCK). After students get lecture and simulating learning, the post-test increased to 63.8% (sufficient category) and PCK revision is also increase 58.1% (growing PCK). It can be concluded that mastery of subject matter could affects the ability of genetic PCK.

Design and Implementation of Hydrologic Process Knowledge-base Ontology: A case study for the Infiltration Process

Elag, M.; Goodall, J. L.

2013-12-01

Hydrologic modeling often requires the re-use and integration of models from different disciplines to simulate complex environmental systems. Component-based modeling introduces a flexible approach for integrating physical-based processes across disciplinary boundaries. Several hydrologic-related modeling communities have adopted the component-based approach for simulating complex physical systems by integrating model components across disciplinary boundaries in a workflow. However, it is not always straightforward to create these interdisciplinary models due to the lack of sufficient knowledge about a hydrologic process. This shortcoming is a result of using informal methods for organizing and sharing information about a hydrologic process. A knowledge-based ontology provides such standards and is considered the ideal approach for overcoming this challenge. The aims of this research are to present the methodology used in analyzing the basic hydrologic domain in order to identify hydrologic processes, the ontology itself, and how the proposed ontology is integrated with the Water Resources Component (WRC) ontology. The proposed ontology standardizes the definitions of a hydrologic process, the relationships between hydrologic processes, and their associated scientific equations. The objective of the proposed Hydrologic Process (HP) Ontology is to advance the idea of creating a unified knowledge framework for components' metadata by introducing a domain-level ontology for hydrologic processes. The HP ontology is a step toward an explicit and robust domain knowledge framework that can be evolved through the contribution of domain users. Analysis of the hydrologic domain is accomplished using the Formal Concept Approach (FCA), in which the infiltration process, an important hydrologic process, is examined. Two infiltration methods, the Green-Ampt and Philip's methods, were used to demonstrate the implementation of information in the HP ontology. Furthermore, a SPARQL

To identify women's beliefs and other factors associated with lack of osteoporosis (OP) pharmacotherapy (OP-RX) during the 6 months after a fragility fracture, including the woman's perspective on fracture risk, OP, and treatment. Cross-sectional. Group Health Cooperative, a mixed-model delivery system. Female Group Health Cooperative enrollees aged 55 and older with an OP-related fracture according to diagnostic and procedure codes from January 1, 2013, to March 30, 2014 (N = 985). OP-RX and participant characteristics were ascertained from electronic health records including medications dispensed. A mailed survey was used to obtain data on health behaviors; OP-related history; concern about, knowledge of, and perceived risk of future fracture; beliefs about OP-RX; sources of information on OP; postfracture discussions with providers; and provider recommendations. The response rate was 73%. Of 634 eligible respondents, 84% did not undergo OP-RX during the 6 months after fracture. Fewer than 20% of women thought that OP caused their fracture, 52% did not think they were at risk of future fracture, and 75% did not think or know whether OP-RX reduces risk of fracture. Knowledge about OP and the benefits of treatment was higher in the 16% of women who underwent OP-RX after their fracture. Women reported low levels of engagement with their healthcare providers regarding OP and fracture risk management. These findings suggest low awareness about OP and its contribution to fracture risk, lack of understanding about the benefits of pharmacotherapy, and limited discussion about OP with primary care physicians. Information about individual's beliefs and knowledge gaps can help design targeted patient and provider education to improve treatment rates. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

Role of sufficient statistics in stochastic thermodynamics and its implication to sensory adaptation

2018-04-01

A sufficient statistic is a significant concept in statistics, which means a probability variable that has sufficient information required for an inference task. We investigate the roles of sufficient statistics and related quantities in stochastic thermodynamics. Specifically, we prove that for general continuous-time bipartite networks, the existence of a sufficient statistic implies that an informational quantity called the sensory capacity takes the maximum. Since the maximal sensory capacity imposes a constraint that the energetic efficiency cannot exceed one-half, our result implies that the existence of a sufficient statistic is inevitably accompanied by energetic dissipation. We also show that, in a particular parameter region of linear Langevin systems there exists the optimal noise intensity at which the sensory capacity, the information-thermodynamic efficiency, and the total entropy production are optimized at the same time. We apply our general result to a model of sensory adaptation of E. coli and find that the sensory capacity is nearly maximal with experimentally realistic parameters.

This study aimed to compare nurses' knowledge and opinion about depression. Sample consisted of 101 nurses in the basic health care network in two cities in the state of São Paulo (Brazil). Subjects answered two questionnaires presented by WHO about knowledge and viewpoints regarding depression. Projects were approved by the Ethics Committee. The profile reveals that graduation time of Group A (Ribeirão Preto), with 28 subjects, is longer than Group B (São José do Rio Preto), with 73 subjects, and work mobility is higher for Group A. There were significative differences between the two groups (T= 0.012 and T=0.666) in these questions. Group B showed greater interest in mental health. No significant differences occurred between the two groups, neither in relation to the knowledge nor in their opinion about depression (Med 7.0 and 7.3). Nevertheless, it was observed lack of specific knowledge, need of updating, lack of experience and unawareness of the importance of their therapeutic role for depressed patients. There are differences in the profile of the two groups; however, there are no significant differences in their knowledge and opinion about depression. In both groups deficit of knowledge and unawareness of nurses about importance of their therapeutic role in depression is observed.

Cellucci, Tania; Lee, Shirley; Webster, Fiona

2016-08-01

Rare rheumatic diseases present unique challenges to knowledge translation (KT) researchers. There is often an urgent need to transfer knowledge from research findings into clinical practice to facilitate earlier diagnosis and better outcomes. However, existing KT frameworks have not addressed the specific considerations surrounding rare diseases for which gold standard evidence is not available. Several widely adopted models provide guidance for processes and problems associated with KT. However, they do not address issues surrounding creation or synthesis of knowledge for rare diseases. Additional problems relate to lack of awareness or experience in intended knowledge users, low motivation, and potential barriers to changing practice or policy. Strategies to address the challenges of KT for rare rheumatic diseases include considering different levels of evidence available, linking knowledge creation and transfer directly, incorporating patient and physician advocacy efforts to generate awareness of conditions, and selecting strategies to address barriers to practice or policy change.

The objective of this study was to identify determinants of human immunodeficiency virus (HIV) knowledge regarding mother-to-child transmission (MTCT) among pregnant women at Tijuana General Hospital, Baja California, Mexico. Between March and November 2003, patients from the prenatal care (n = 1294) and labor and delivery (L&D) units (n = 495) participated in a cross-sectional study to measure HIV knowledge. Less than one-third (30%) knew that HIV could be transmitted to a child during delivery, and 36% knew that HIV could be transmitted by breast-feeding. Only 27% knew that an MTCT could be prevented. Prenatal patients were more likely to know that MTCT was preventable (prenatal: 31% versus L&D 25%; P = .02). Logistic regression indicated that prenatal patients (odds ratio = 1.49, confidence interval 1.07-2.07) were more likely to know that HIV could be transmitted through breast-feeding. Overall, both groups had poor knowledge regarding MTCT of HIV. © The Author(s) 2014.

To examine doctors' level of knowledge of the law on withholding and withdrawing life-sustaining treatment from adults who lack decision-making capacity, and factors associated with a higher level of knowledge. Postal survey of all specialists in emergency medicine, geriatric medicine, intensive care, medical oncology, palliative medicine, renal medicine and respiratory medicine on the AMPCo Direct database in New South Wales, Victoria and Queensland. Survey initially posted to participants on 18 July 2012 and closed on 31 January 2013. Medical specialists' levels of knowledge about the law, based on their responses to two survey questions. Overall response rate was 32%. For the seven statements contained in the two questions about the law, the mean knowledge score was 3.26 out of 7. State and specialty were the strongest predictors of legal knowledge. Among doctors who practise in the end-of-life field, there are some significant knowledge gaps about the law on withholding and withdrawing life-sustaining treatment from adults who lack decision-making capacity. Significant consequences for both patients and doctors can flow from a failure to comply with the law. Steps should be taken to improve doctors' legal knowledge in this area and to harmonise the law across Australia.

Direct eye contact and motion onset both constitute powerful cues that capture attention. Recent research suggests that (social) gaze and (non-social) motion onset influence information processing in parallel, even when combined as sudden onset direct gaze cues (i.e., faces suddenly establishing eye contact). The present study investigated the role of eye visibility for attention capture by these sudden onset face cues. To this end, face direction was manipulated (away or towards onlooker) while faces had closed eyes (eliminating visibility of eyes, Experiment 1), wore sunglasses (eliminating visible eyes, but allowing for the expectation of eyes to be open, Experiment 2), and were inverted with visible eyes (disrupting the integration of eyes and faces, Experiment 3). Participants classified targets appearing on one of four faces. Initially, two faces were oriented towards participants and two faces were oriented away from participants. Simultaneous to target presentation, one averted face became directed and one directed face became averted. Attention capture by face direction (i.e., facilitation for faces directed towards participants) was absent when eyes were closed, but present when faces wore sunglasses. Sudden onset direct faces can, hence, induce attentional capture, even when lacking eye cues. Inverted faces, by contrast, did not elicit attentional capture. Thus, when eyes cannot be integrated into a holistic face representation they are not sufficient to capture attention. Overall, the results suggest that visibility of eyes is neither necessary nor sufficient for the sudden direct face effect. Copyright © 2015 Elsevier B.V. All rights reserved.

Federal attempts to stimulate technological innovation have been unsuccessful because of the application of an inappropriate policy framework that lacks conceptual and empirical knowledge of the process of technological innovation and fails to acknowledge the relationship between knowled reproduction, transfer, and use as equally important components of the process of knowledge diffusion. It is argued that the potential contributions of high-speed computing and networking systems will be diminished unless empirically derived knowledge about the information-seeking behavior of the members of the social system is incorporated into a new policy framework. Findings from the NASA/DoD Aerospace Knowledge Diffusion Research Project are presented in support of this assertion.

Camponogara, Silviamar; Ramos, Flávia Regina Sousa; Kirchhof, Ana Lucia Cardoso

2009-01-01

The article aims to analyze the interface of reflexivity, knowledge and ecologic awareness in the context of hospital work, based on data collected in a qualitative case study carried out at a public hospital. Field observation data and interviews are discussed in the light of sociologic and philosophic references. Workers expressed the interface between knowledge and action, in which there is a cycle of lack of knowledge, automatism in the actions and lack of environmental awareness, posing limits to individual awareness and to responsibility towards environmental preservation. Increased debate and education, including the environmental issue, are needed in the context of hospital work. Although hospital work is reflexively affected by the environmental problem, that does not guarantee the reorientation of practices and responsible action towards the environment.

Athletes obtain nutritional information from their coaches, yet their competency in this area is lacking. Currently, no research exists in the UK which has a different coach education system to many other countries. Therefore, the aim of this study was to evaluate the sports nutrition knowledge of UK coaching certificate (UKCC) level 2 and 3, hockey and netball qualified coaches. All coaches (n = 163) completed a sports nutrition questionnaire to identify: (a) if they provided nutritional advice; (b) their level of sport nutrition knowledge; and (c) factors that may have contributed to their level of knowledge. Over half the coaches provided advice to their athletes (n = 93, 57.1%), even though they were not competent to do so. Coaches responded correctly to 60.3 ± 10.5% of all knowledge questions with no differences between those providing advice and those who did not (p > 0.05). Those coaches who had undertaken formal nutrition training achieved higher scores than those who had not (p < 0.05). In conclusion, UK sports coaches would benefit from continued professional development in sports nutrition to enhance their coaching practice. PMID:24727434

What Did They Learn? Effects of a Brief Cognitive Behavioral Therapy Workshop on Community Therapists' Knowledge.

2016-11-01

Knowledge gain has been identified as necessary but not sufficient for therapist behavior change. Declarative knowledge, or factual knowledge, is thought to serve as a prerequisite for procedural knowledge, the how to knowledge system, and reflective knowledge, the skill refinement system. The study aimed to examine how a 1-day workshop affected therapist cognitive behavioral therapy declarative knowledge. Participating community therapists completed a test before and after training that assessed cognitive behavioral therapy knowledge. Results suggest that the workshop significantly increased declarative knowledge. However, post-training total scores remained moderately low, with several questions answered incorrectly despite content coverage in the workshop. These findings may have important implications for structuring effective cognitive behavioral therapy training efforts and for the successful implementation of cognitive behavioral therapy in community settings.

The abundance of recent studies on the relationship between oral diseases and complications of pregnancy leads to questions on knowledge of health professionals. This study aims to establish an inventory of knowledge and practice of health professionals in France on this issue. A questionnaire on knowledge of the relationship between oral diseases and complications of pregnancy was referred to gynaecologists and obstetricians, midwives and dentists. This study was conducted at the University Hospital of Nantes and Le Mans General Hospital. Eighty-seven professionals of pregnancy and 259 dentists responded to the survey. Bleeding gums and pregnancy gingivitis are the oral manifestations most cited by all practitioners. There is however a difference concerning the epulis and caries risk. The most cited Pregnancy complications are risk of premature delivery and chorioamniotitis. Only dentists had received initial training on pregnancy complications. Finally, all health professionals point to the lack of continued education on this topic. There is a good knowledge of the pregnancy complications associated with oral disease despite the lack of training of pregnancy, but the attitudes of care are not still in adequacy. It appears necessary to strengthen the training of all practitioners in this field. The design and implementation of a specific questionnaire on oral health status could allow better identification of the patients at risk by the professionals of pregnancy, and optimize so the care of pregnant women.

2017-11-01

The number of organ donors in Italy is increasing, but with still disappointing living donation activity and relatively frequent objection by potential deceased donors' relatives to organ recovery. Few studies have assessed health care students' knowledge and attitude on donation. We administered a questionnaire to medical (MS) and nursing students (NS) at University of Modena and Reggio Emilia, Italy, and 749 students (406 MS and 343 NS) completed the questionnaire. Although 95% of students were in favor of donation, only 21.9% of NS and 24.9% of MS were registered as donors. One quarter of students reported family disagreement. MS appeared more confident with personnel involved in donation. Overall, 60% of students knew the term donation after brain death but only 40% were aware of the criteria used to define it. Barely 27.1% of NS and 15.3% of MS believed they had received sufficient information in lessons. Backward logistic regression demonstrated that students whose families agree with them and who knew the definition of donation after brain death were more likely to express the disposition of registering, and those who showed distrust in the declaration of brain death were half as likely to register as donors. Students expressed a lack of knowledge, controversial attitudes on donation, and strong need for education; increased awareness may help increase donation rates. The majority of educational institutions in Italy do not directly address training on organ donation and transplantation for health care students; an integrated curriculum favoring interpersonal discussion including practical aspects is urgently required.

Rett syndrome (RTT) is a neurodevelopmental disorder caused by mutations in Methyl-CpG-binding protein 2 (MECP2). Severe breathing abnormalities are common in RTT and are reproduced in mouse models of RTT. Previously, we found that removing MeCP2 from the brainstem and spinal cord in mice caused early lethality and abnormal breathing. To determine whether loss of MeCP2 in functional components of the respiratory network causes specific breathing disorders, we used the Cre/LoxP system to differentially manipulate MeCP2 expression throughout the brainstem respiratory network, specifically within HoxA4-derived tissues, which include breathing control circuitry within the nucleus tractus solitarius and the caudal part of ventral respiratory column but do not include more rostral parts of the breathing control circuitry. To determine whether respiratory phenotypes manifested in animals with MeCP2 removed from specific pons medullary respiratory circuits, we performed whole-body plethysmography and electrophysiological recordings from in vitro brainstem slices from mice lacking MeCP2 in different circuits. Our results indicate that MeCP2 expression in the medullary respiratory network is sufficient for normal respiratory rhythm and preventing apnea. However, MeCP2 expression within components of the breathing circuitry rostral to the HoxA4 domain are neither sufficient to prevent the hyperventilation nor abnormal hypoxic ventilatory response. Surprisingly, we found that MeCP2 expression in the HoxA4 domain alone is critical for survival. Our study reveals that MeCP2 is differentially required in select respiratory components for different aspects of respiratory functions, and collectively for the integrity of this network functions to maintain proper respiration. Breathing abnormalities are a significant clinical feature in Rett syndrome and are robustly reproduced in the mouse models of this disease. Previous work has established that alterations in the function of Me

A total of 126 patients, most of them women, with an average age of 44.6 years were included. Half of the study population had no knowledge which could ensure the correct use of the antibiotic they were taking. The «process of use» of the medication was the best known dimension by the study population, followed by the «therapeutic aim». The dimension related to the «safety» of the medication was the one with the lowest values. After a logistic regression, a link between the knowledge of the antibiotic and the «know the name of the antibiotic» (p=.05; r=2.15) and the «number of antibiotic the patient takes» (p=.02; r=0.30) variables. The results show that there is a certain lack of information on the use of antibiotics by the study sample. Thes results could help to show the way to follow in future studies, targeted to meet the need of information. Copyright © 2013 Elsevier España, S.L.U. All rights reserved.

2017-11-01

The aim of this hospital-based, cross-sectional study was to examine nurses' knowledge, personal and professional practices and attitude towards complementary and alternative medical therapies in urban Ghana. Using convenience sampling technique, cross-sectional data were collected from 210 registered and practicing nurses with self-administered questionnaire based on the Complementary and Alternative Medicine (CAM) Health Belief Questionnaire (CHBQ). Descriptive statistics and the associations between variables were calculated using Pearson's Chi-square test and/or Fisher's exact test with p < 0.05. The mean score of nurses' knowledge on CAM therapies was low (mean ± SD, 38.39 ± 10.11; possible range, 18-72) which was built on nurses' personal experiences. Nurses, therefore, lacked the confidence to recommend CAM therapies to patients. Despite the isolated cases of non-herbal supplements, relaxation techniques, massage and prayer healing, the study found an overall low personal use of CAM (mean ± SD, 32.97 ± 10.78; possible range, 18-72) among nurses over the last 12 months. Yet, nurses exhibited a positive attitude towards CAM (mean ± SD, 72.7 ± 12.5, possible range, 67-110). We observed significant associations among nurses' CAM knowledge and education [χ 2 (2) = 6.69, p = 0.035] and religion [χ 2 (2) = 7.96, p = 0.019]; nurses' personal use of CAM and income [χ 2 (2) = 16.07, p < 0.001] and religion [χ 2 (2) = 18.65, p < 0.001]; and nurses' clinical CAM use and income [χ 2 (2) = 7.01, p = 0.030]. Despite the overall positive attitude towards CAM therapies, Ghanaian nurses do not perceive themselves to have sufficient knowledge of CAM. Integrating CAM education into the nurses' training curriculum can improve CAM knowledge and professional practice among nurses, and in turn, enhance evidence-based patient care within the framework of intercultural healthcare system in Ghana.

What's your strategy for managing knowledge?

PubMed

Hansen, M T; Nohria, N; Tierney, T

1999-01-01

The rise of the computer and the increasing importance of intellectual assets have compelled executives to examine the knowledge underlying their businesses and how it is used. Because knowledge management as a conscious practice is so young, however, executives have lacked models to use as guides. To help fill that gap, the authors recently studied knowledge management practices at management consulting firms, health care providers, and computer manufacturers. They found two very different knowledge management strategies in place. In companies that sell relatively standardized products that fill common needs, knowledge is carefully codified and stored in databases, where it can be accessed and used--over and over again--by anyone in the organization. The authors call this the codification strategy. In companies that provide highly customized solutions to unique problems, knowledge is shared mainly through person-to-person contacts; the chief purpose of computers is to help people communicate. They call this the personalization strategy. A company's choice of knowledge management strategy is not arbitrary--it must be driven by the company's competitive strategy. Emphasizing the wrong approach or trying to pursue both can quickly undermine a business. The authors warn that knowledge management should not be isolated in a functional department like HR or IT. They emphasize that the benefits are greatest--to both the company and its customers--when a CEO and other general managers actively choose one of the approaches as a primary strategy.

To investigate the knowledge, attitude and practice related to evidence-based dentistry among dental students, and to provide a reference for targeted evidence-based dentistry teaching and practice evidence-based dentistry in dental students. Dental students who attended the internship in Shanghai Ninth People's Hospital and Pudong People's Hospital were invited to attend this survey. Information on knowledge, attitude and practices related evidence-based dentistry was collected through questionnaires. SPSS 21.0 software package was used for data analysis. A total of 62 dental students attended this survey. Evidence-based dentistry related knowledge and attitude scores were 5.5±1.9 and 5.1±1.0, respectively. Over three quarters of students took courses on evidence-based medicine, while around half of students (56.5%) self-reported that they knew little about evidence-based medicine. 70.5% students practiced evidence-based dentistry less than once in the process of clinical decision making per week. The majority of students (80.3%) used MEDLINE or other databases to search for practice-related literature less than once per week. 63.9% students used practice guideline. The top three barriers to practice evidence-based dentistry were lack of information resources, insufficient time and lack of search skills. Evidence-based dentistry related knowledge and practice among dental students is deficient, whereas they hold positive attitude on practice. The top three barriers to practice evidence-based dentistry are lack of information resources, insufficient time and lack of search skills.

Preschoolers acquire general knowledge by sharing in pretense.

PubMed

Sutherland, Shelbie L; Friedman, Ori

2012-01-01

Children acquire general knowledge about many kinds of things, but there are few known means by which this knowledge is acquired. In this article, it is proposed that children acquire generic knowledge by sharing in pretend play. In Experiment 1, twenty-two 3- to 4-year-olds watched pretense in which a puppet represented a "nerp" (an unfamiliar kind of animal). For instance, in one scenario, the nerp ate and disliked a carrot. When subsequently asked generic questions about real nerps, children's responses suggested that they had learned general facts (e.g., nerps dislike carrots). In Experiment 2, thirty-two 4- to 5-year-olds learned from scenarios lacking pretend speech or sound effects. The findings reveal a long overlooked means by which children can acquire generic knowledge. © 2012 The Authors. Child Development © 2012 Society for Research in Child Development, Inc.

To determine barriers to nutrition education, nutrition education resources used, and the relationship between nutrition knowledge and whether public school teachers in California teach nutrition in the classroom. A total of 102 teachers in California participated in a Web-based survey about nutrition education barriers, resources used to plan nutrition lessons, and factors that would encourage inclusion of nutrition. A validated questionnaire was used to assess nutrition knowledge. Analyses included ordinary least-squares regression. Common barriers were lack of instructional time and unrelated subject. Teachers were unaware of many nutrition education resources. Nutrition knowledge was not associated with nutrition lessons but was positively associated with teaching high school (β = 5.13; P < .05) and female gender (β = 6.78; P < .05), and negatively associated with identifying as Hispanic or Latino (β = -15.50; P < .001). Barriers of time and lack of unrelated subject matter are difficult to address but lack of awareness of resources indicates that promotion of existing resources may encourage teachers to provide nutrition education. Larger studies are needed to determine whether this holds true in a broader sample. Copyright © 2015 Society for Nutrition Education and Behavior. Published by Elsevier Inc. All rights reserved.

Mammary ductal growth is impaired in mice lacking leptin-dependent signal transducer and activator of transcription 3 signaling.

PubMed

Thorn, Stephanie R; Giesy, Sarah L; Myers, Martin G; Boisclair, Yves R

2010-08-01

Mice lacking leptin (ob/ob) or its full-length receptor (db/db) are obese and reproductively incompetent. Fertility, pregnancy, and lactation are restored, respectively, in ob/ob mice treated with leptin through mating, d 6.5 post coitum, and pregnancy. Therefore, leptin signaling is needed for lactation, but the timing of its action and the affected mammary process remain unknown. To address this issue, we used s/s mice lacking only leptin-dependent signal transducer and activator of transcription (STAT)3 signaling. These mice share many features with db/db mice, including obesity, but differ by retaining sufficient activity of the hypothalamic-pituitary-ovarian axis to support reproduction. The s/s mammary epithelium was normal at 3 wk of age but failed to expand through the mammary fat pad (MFP) during the subsequent pubertal period. Ductal growth failure was not corrected by estrogen therapy and did not relate to inadequate IGF-I production by the MFP or to the need for epithelial or stromal leptin-STAT3 signaling. Ductal growth failure coincided with adipocyte hypertrophy and increased MFP production of leptin, TNFalpha, and IL6. These cytokines, however, were unable to inhibit the proliferation of a collection of mouse mammary epithelial cell lines. In conclusion, the very first step of postnatal mammary development fails in s/s mice despite sufficient estrogen IGF-I and an hypothalamic-pituitary-ovarian axis capable of supporting reproduction. This failure is not caused by mammary loss of leptin-dependent STAT3 signaling or by the development of inflammation. These data imply the existence of an unknown mechanism whereby leptin-dependent STAT3 signaling and obesity alter mammary ductal development.

Aims and Objectives: Biomedical waste management has become a concern with increasing number of dental practitioners in India. Being health care professionals, dentists should be aware regarding safe disposal of biomedical waste and recycling of dental materials to minimize biohazards to the environment. The aim of the present study was to assess awareness regarding biomedical waste management as well as knowledge of effective recycling and reuse of dental materials among dental students. Materials and Methods: This cross-sectional study was conducted among dental students belonging from all dental colleges of Bhubaneswar, Odisha (India) from February 2016 to April 2016. A total of 500 students (208 males and 292 females) participated in the study, which was conducted in two phases. A questionnaire was distributed to assess the awareness of biomedical waste management and knowledge of effective recycling of dental materials, and collected data was examined on a 5-point unipolar scale in percentages to assess the relative awareness regarding these two different categorizes. The Statistical Package for Social Sciences was used to analyzed collected data. Results: Forty-four percent of the dental students were not at all aware about the management of biomedical waste, 22% were moderately aware, 21% slightly aware, 7% very aware, and 5% fell in extremely aware category. Similarly, a higher percentage of participants (61%) were completely unaware regarding recycling and reusing of biomedical waste. Conclusion: There is lack of sufficient knowledge among dental students regarding management of biomedical waste and recycling or reusing of dental materials. Considering its impact on the environment, biomedical waste management requires immediate academic assessment to increase the awareness during training courses. PMID:27891315

Experts’ and Novices’ Perception of Ignorance and Knowledge in Different Research Disciplines and Its Relation to Belief in Certainty of Knowledge

PubMed Central

Hansson, Isabelle; Buratti, Sandra; Allwood, Carl Martin

2017-01-01

Assessments of the extent of knowledge in a domain can be important since non-identified lack of knowledge may lead to decisions that do not consider the effect of relevant factors. Two studies examined experts’ and novices’ perception of their own ignorance and knowledge out of everything there is to know within their own and other disciplines and their assessments of their discipline’s, and other disciplines’ knowledge of all there is to know in each discipline. In total 380 experts and 401 students from the disciplines of history, medicine, physics, and psychology participated. The results for ignorance and knowledge assessments of one’s own knowledge were similar. Novices reported more ignorance and less knowledge in their own discipline than experts, but no differences were found in the assessments of how much is known in each discipline. General belief in certainty of knowledge was associated with the knowledge assessments and level of expertise. Finally, disciplinary differences were found both for the knowledge assessments and for belief in certainty of knowledge. Historians and physicists assessed that less was known in their own discipline out of all there is to know (approximately 40%), compared to the medics (about 50%). Historians believed least in certainty of knowledge and physicists most. Our results have practical implications for higher educational teaching and interdisciplinary collaboration. PMID:28367132

Few studies have explored the knowledge and attitudes of adolescents toward cancer prevention and treatment. This lack of research and its potential utility in the development of new educational initiatives and screening methods, or the reconstruction of existing ones, provided the impetus for this study. The primary research aim was to assess secondary school student knowledge of cancer and determine whether or not they possessed basic knowledge of cancer symptoms, risk factors, and treatments and to determine the relationship between cancer knowledge and key demographic factors. The Management and Science University conducted a cross-sectional study analyzing responses through cross-tabulation with the socio-demographic data collected. The findings of our quantitative analysis suggest that Malaysian youth generally possess a moderate knowledge about cancer. Quantitative analyses found that socioeconomic inequalities and bias in education present as important factors contributing to cancer awareness, prevention, and treatment among Malaysian adolescents. The findings indicate that Malaysian youth generally possess a moderate knowledge about cancer but the current deficiencies in initiatives directed to cancer awareness continue to hinder the improvement in prevention of cancer among Malaysian adolescents.

This study questions the presumed relation between formal schooling and scientific literacy about biotechnologies. Comparing science and nonscience majors' knowledge of and attitudes toward biotechnological applications, conclusions are drawn if their formal learnings improve pupils' understandings of and attitudes toward biotechnology applications. Sample of the study consists of 403 undergraduate and graduate students, 198 nonscience, and 205 science majors. The Biotechnology Knowledge Questionnaire and the Biotechnology Attitude Questionnaire were administered. Descriptive statistics (mean and percentages), t test, and correlations were used to examine the participants' knowledge of biotechnology and attitudes toward biotechnological applications and differences as regards their majors. Although the science majors had higher knowledge and attitude scores than the nonscience majors, it is not possible to say that they have sufficient knowledge of biotechnologies. Besides, the participants' attitudes toward biotechnological applications were not considerably related to their knowledge of biotechnology. © 2016 by The International Union of Biochemistry and Molecular Biology, 45(2):115-125, 2017. © 2016 The International Union of Biochemistry and Molecular Biology.

Although crucial, research on nurses' knowledge on the use of implantable cardioverter defibrillators (ICDs) is scant. The aims of the study were to investigate (i) the level of nurses' knowledge on care of patients with ICDs, (ii) whether knowledge level is related to education and type of hospital where nurses practice and (iii) whether knowledge level changes among nurses over time. We developed a questionnaire comprising 27 items in four parts: (1) Sociodemographics, (2) Technical facts about ICDs, (3) Daily life challenges and (4) Self-evaluation of knowledge. After validation, surveys were conducted during 1-week cardiac educational courses in 2003-2010. In total, 463 nurses working in cardiology-related areas participated, yielding a response rate of 91%. Practical and technical knowledge about ICDs was lacking. Nurses were unaware or did not know that mobile phones can affect the device (80%), that patients are restricted from driving heavy vehicles (69%), and that ICDs can deliver unintended shock therapy (73%). However, they were aware that ICD patients can resume sexual (87%) and physical activity (85%). There were few significant differences with regard to education and type of hospital where nurses practiced, but significant time trends in correct answers regarding kitchen appliances, resumption of physical activity and shock delivery. Over an 8-year period, despite the increased usage of ICDs, overall nurses had a lack of knowledge in relation to specific key clinical issues on the care of ICD patients. As a consequence, these patients may fail to receive qualified care. Future research should assess knowledge of other health care professionals and focus on interventions that increase and maintain an appropriate knowledge level in care of ICD patients. Relevance to clinical practice The level of nurses' knowledge on care of patients with ICDs needs to be systematically raised in order to ensure appropriate counselling and nursing care. © 2014 British

Redox self-sufficient whole cell biotransformation for amination of alcohols.

PubMed

Klatte, Stephanie; Wendisch, Volker F

2014-10-15

Whole cell biotransformation is an upcoming tool to replace common chemical routes for functionalization and modification of desired molecules. In the approach presented here the production of various non-natural (di)amines was realized using the designed whole cell biocatalyst Escherichia coli W3110/pTrc99A-ald-adh-ta with plasmid-borne overexpression of genes for an l-alanine dehydrogenase, an alcohol dehydrogenase and a transaminase. Cascading alcohol oxidation with l-alanine dependent transamination and l-alanine dehydrogenase allowed for redox self-sufficient conversion of alcohols to the corresponding amines. The supplementation of the corresponding (di)alcohol precursors as well as amino group donor l-alanine and ammonium chloride were sufficient for amination and redox cofactor recycling in a resting buffer system. The addition of the transaminase cofactor pyridoxal-phosphate and the alcohol dehydrogenase cofactor NAD(+) was not necessary to obtain complete conversion. Secondary and cyclic alcohols, for example, 2-hexanol and cyclohexanol were not aminated. However, efficient redox self-sufficient amination of aliphatic and aromatic (di)alcohols in vivo was achieved with 1-hexanol, 1,10-decanediol and benzylalcohol being aminated best.

Khanal, K; Maharjan, R; Pokharel, B R; Sanjel, S

2015-01-01

Background Studies on Knowledge towards epilepsy among school teachers are very limited on developing countries especially with reference to Nepal. Level of knowledge of schoolteachers plays an important role on providing a greater educational support for epileptic child and to maintain good communication skills between epileptic and normal child. Objective Objective of this study is to assess the level of knowledge about epilepsy and its associated factors among school teachers. Method A cross sectional study was conducted from 10th June to 4th July, 2014 among 165 teachers teaching in six different schools of Kathmandu Metropolitan City. A selfadministrated questionnaire consisting of structured and multiple choice questions were designed to collect information on the teacher's socio-demographic profile and knowledge about epilepsy. A scoring system was developed for each question: each correct answer was given a score of 1, and a score of 0 for wrong answer. Total score was categorized on two categories: Good Knowledge and Poor Knowledge. Result Teacher's age did not correlate significantly with their knowledge about epilepsy but total years of teaching experiences and knowledge about epilepsy were found to be positively correlated (ρ= 0.165, p= 0.01). Academic qualification of teachers and different teaching level were associated with level of knowledge (p= 0.023, p= 0.021). Significant difference on knowledge score was found among teachers having different academic qualification (p= 0.019). Conclusion All teachers were aware about epilepsy, but their knowledge about epilepsy was not sufficient therefore, health education training program about epilepsy is needed for teachers.

Vaccine procurement and self-sufficiency in developing countries.

PubMed

Woodle, D

2000-06-01

This paper discusses the movement toward self-sufficiency in vaccine supply in developing countries (and countries in transition to new economic and political systems) and explains special supply concerns about vaccine as a product class. It traces some history of donor support and programmes aimed at self-financing, then continues with a discussion about self-sufficiency in terms of institutional capacity building. A number of deficiencies commonly found in vaccine procurement and supply in low- and middle-income countries are characterized, and institutional strengthening with procurement technical assistance is described. The paper also provides information about a vaccine procurement manual being developed by the United States Agency for International Development (USAID) and the World Health Organization (WHO) for use in this environment. Two brief case studies are included to illustrate the spectrum of existing capabilities and different approaches to technical assistance aimed at developing or improving vaccine procurement capability. In conclusion, the paper discusses the special nature of vaccine and issues surrounding potential integration and decentralization of vaccine supply systems as part of health sector reform.

Information trimming: Sufficient statistics, mutual information, and predictability from effective channel states

NASA Astrophysics Data System (ADS)

James, Ryan G.; Mahoney, John R.; Crutchfield, James P.

2017-06-01

One of the most basic characterizations of the relationship between two random variables, X and Y , is the value of their mutual information. Unfortunately, calculating it analytically and estimating it empirically are often stymied by the extremely large dimension of the variables. One might hope to replace such a high-dimensional variable by a smaller one that preserves its relationship with the other. It is well known that either X (or Y ) can be replaced by its minimal sufficient statistic about Y (or X ) while preserving the mutual information. While intuitively reasonable, it is not obvious or straightforward that both variables can be replaced simultaneously. We demonstrate that this is in fact possible: the information X 's minimal sufficient statistic preserves about Y is exactly the information that Y 's minimal sufficient statistic preserves about X . We call this procedure information trimming. As an important corollary, we consider the case where one variable is a stochastic process' past and the other its future. In this case, the mutual information is the channel transmission rate between the channel's effective states. That is, the past-future mutual information (the excess entropy) is the amount of information about the future that can be predicted using the past. Translating our result about minimal sufficient statistics, this is equivalent to the mutual information between the forward- and reverse-time causal states of computational mechanics. We close by discussing multivariate extensions to this use of minimal sufficient statistics.

CONTEXT: Scientific research not only promotes health and combats diseases of an individual, but also it can strengthen the effectiveness of health systems. Hence, understanding of scientific methods becomes a crucial component in the medical profession. AIMS: This study was conducted to assess the knowledge, attitudes, and barriers toward research among undergraduate medical and dental students. SETTINGS AND DESIGN: This cross-sectional study was conducted among 295 undergraduate Bachelor of Medicine and Bachelor of Surgery (MBBS) and Bachelor of Dental Surgery (BDS) students from a private medical college in Malaysia. MATERIALS AND METHODS: We purposively selected 360 students attending the 3rd, 4th, and 5th year in MBBS course and BDS course in September 2015. A total of 295 students who were willing to provide written informed consent were included in this study. We collected data using a validated, self-administered, structured questionnaire which included 20 questions about knowledge toward scientific research, 21 attitude items in regard to scientific research, a list of 10 barriers toward conducting medical research, and 5 questions of confidence to conduct the medical research. STATISTICAL ANALYSIS USED: Data were analyzed using descriptive statistics, independent t-test, ANOVA, and multiple linear regression. RESULTS: Among the students, 56.9% had moderate knowledge while the majority (83.3%) had moderate attitude toward scientific research. The majorly cited barriers were the lack of time (79.9%), lack of knowledge and skills (72.1%), lack of funding (72.0%) and facilities (63.6%), and lack of rewards (55.8%). There was a significant association between age, academic year, and knowledge of research as the older age group, and 4th- and 5th-year students had higher knowledge score. The students of higher attitude score had better-perceived barriers score toward research with regression coefficient 0.095 (95% confidence interval 0.032–0.159). CONCLUSIONS

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.

Paço, Arminda; Lavrador, Tânia

2017-07-15

Numerous investigations have arisen in order to study and characterise environmentally friendly consumer profiles, with some authors applying the relationship between knowledge, attitudes and behaviour to this end. The present research approach, based upon the Theory of Reasoned Action (TRA), seeks to verify the existence of relationships between knowledge and attitudes and between knowledge and environmental behaviour. In this instance, data collection involved a questionnaire aimed at assessing the overall environmental knowledge of respondents as well as their attitudes and behaviours regarding energy issues (savings, consumption, interest, use). The results pointed to the lack of relationship between knowledge and attitudes, and between knowledge and behaviour whilst the relationship between attitudes and behaviour proved to be only weak. The results also found that males, older students and those studying Engineering and the Social and Human Sciences are those reporting higher levels of environmental knowledge. However, when it comes to attitudes and behaviours, females seem to display more awareness around these issues. Copyright © 2017 Elsevier Ltd. All rights reserved.

The consequences of periodontal disease are not limited to the oral cavity. As schools are considered to be one of the principal systems in preventive oral health, teachers' knowledge pertaining to the periodontal disease, their awareness with regard to its implications and their role in increasing the awareness of the students regarding this disease comprises only one aspect with respect to the prevention of the periodontal disease. Therefore, the aim of this study is to investigate the baseline awareness and knowledge of Saudi primary school teachers regarding the periodontal disease. For this purpose, a questionnaire was distributed among the participants of the study. It was observed that 91.4% of the participants reported that the periodontal disease does not need any treatment although 70% of the participants believed that it could result in tooth loss, and 95% considered the periodontal disease to be a preventable disease. Moreover, social media (44%) and television advertisements (39%) were the main sources from where they acquired information about the periodontal disease. Most participants have heard about the importance of periodontal health but are not sufficiently aware of its consequences and negative effects on their body. They are used to receiving information about periodontal diseases from nondental clinics and unreliable sources. This creates misconceptions. Although the participants were keen to attend educational events on periodontal health, the lack of medical communication between the health practitioners and the general public is evident. Mostly, investigated areas and individuals do not have any educational means to be aware of periodontal health.

Bone morphogenetic proteins 4 and 7 (BMP4 and BMP7) are morphogens that signal as either homodimers or heterodimers to regulate embryonic development and adult homeostasis. BMP4/7 heterodimers exhibit markedly higher signaling activity than either homodimer, but the mechanism underlying the enhanced activity is unknown. BMPs are synthesized as inactive precursors that dimerize and are then cleaved to generate both the bioactive ligand and prodomain fragments, which lack signaling activity. Our study reveals a previously unknown requirement for the BMP4 prodomain in promoting heterodimer activity. We show that BMP4 and BMP7 precursor proteins preferentially or exclusively form heterodimers when coexpressed in vivo. In addition, we show that the BMP4 prodomain is both necessary and sufficient for generation of stable heterodimeric ligands with enhanced activity and can enable homodimers to signal in a context in which they normally lack activity. Our results suggest that intrinsic properties of the BMP4 prodomain contribute to the relative bioactivities of homodimers versus heterodimers in vivo. These findings have clinical implications for the use of BMPs as regenerative agents for the treatment of bone injury and disease.

Evaluation of Cabin Crew Technical Knowledge

Dunbar, Melisa G.; Chute, Rebecca D.; Jordan, Kevin

1998-01-01

Accident and incident reports have indicated that flight attendants have numerous opportunities to provide the flight-deck crew with operational information that may prevent or essen the severity of a potential problem. Additionally, as carrier fleets transition from three person to two person flight-deck crews, the reliance upon the cabin crew for the transfer of this information may increase further. Recent research (Chute & Wiener, 1996) indicates that light attendants do not feel confident in their ability to describe mechanical parts or malfunctions of the aircraft, and the lack of flight attendant technical training has been referenced in a number of recent reports (National Transportation Safety Board, 1992; Transportation Safety Board of Canada, 1995; Chute & Wiener, 1996). The present study explored both flight attendant technical knowledge and flight attendant and dot expectations of flight attendant technical knowledge. To assess the technical knowledge if cabin crewmembers, 177 current flight attendants from two U.S. carriers voluntarily :ompleted a 13-item technical quiz. To investigate expectations of flight attendant technical knowledge, 181 pilots and a second sample of 96 flight attendants, from the same two airlines, completed surveys designed to capture each group's expectations of operational knowledge required of flight attendants. Analyses revealed several discrepancies between the present level of flight attendants.

Nurses are primary responsible for Direct Observation Therapy Strategy and administration of anti-tuberculosis (TB) medications. Lack of knowledge might result with medication errors and ineffective TB control. The purpose of this study was to assess knowledge of nurses about anti-TB treatment. A descriptive cross-sectional study was conducted in Turkey with 208 nurses employed at TB and lung disease clinics of health-care settings in Ankara. Data were collected through a questionnaire, which included questions about demographics and a knowledge test with true-false questions related to TB treatment. Overall scores were high with a mean score of 18.5 out of 24, but there was knowledge deficiency in effects and side-effects of anti-TB drugs. Knowledge is foundational for any practice and for TB control. Clinical experience and continuing education after graduation influence the level of knowledge. © 2013 Wiley Publishing Asia Pty Ltd.

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.

2013-05-01

The aim of our study was to gain understanding of different types of conflicts on knowledge in the discussions of problem-based learning tutorial groups, and how such conflicts are dealt with. We examined first-year medical and dental students' (N = 33) conflicts on knowledge in four videotaped reporting phase tutorials. A coding scheme was created for analysing verbatim transcripts of 43 conflict episodes in order to find out whether the conflict episodes were about factual or conceptual knowledge and how the students elaborated the knowledge. Conflict episodes were relatively rare (taking up 7.6 % of the time) in the videotaped groups. Conflict episodes were more frequently about factual knowledge (58 %) than conceptual knowledge (42 %), but conflicts on conceptual knowledge lasted longer and were more often elaborated. Elaboration was, however, more frequently done individually than collaboratively. Conflict episodes were generally fairly short (mean duration 28 s). This was due to a lack of thorough argumentation and collaborative elaboration of conflicting ideas. The results suggest that students' skills to bring out differences in each other's conceptual thinking, the depth of argumentation and the use of questions that elicit elaboration need to be improved. Tutors' skills to facilitate the collaborative resolving of conflicts on knowledge call for further study.

How, When, and Where? Assessing Renewable Energy Self-Sufficiency at the Neighborhood Level.

2018-02-20

Self-sufficient decentralized systems challenge the centralized energy paradigm. Although scholars have assessed specific locations and technological aspects, it remains unclear how, when, and where energy self-sufficiency could become competitive. To address this gap, we develop a techno-economic model for energy self-sufficient neighborhoods that integrates solar photovoltaics (PV), conversion, and storage technologies. We assess the cost of 100% self-sufficiency for both electricity and heat, comparing different technical configurations for a stylized neighborhood in Switzerland and juxtaposing these findings with projections on market and technology development. We then broaden the scope and vary the neighborhood's composition (residential share) and geographic position (along different latitudes). Regarding how to design self-sufficient neighborhoods, we find two promising technical configurations. The "PV-battery-hydrogen" configuration is projected to outperform a fossil-fueled and grid-connected reference configuration when energy prices increase by 2.5% annually and cost reductions in hydrogen-related technologies by a factor of 2 are achieved. The "PV-battery" configuration would allow achieving parity with the reference configuration sooner, at 21% cost reduction. Additionally, more cost-efficient deployment is found in neighborhoods where the end-use is small commercial or mixed and in regions where seasonal fluctuations are low and thus allow for reducing storage requirements.

Child abuse is a serious public problem. Signs of abuse are often present in the oro-facial region and dentists are in a strategic position to recognise and report suspected cases. The aim of this study was to investigate dental students' knowledge about and attitudes towards child abuse. This study was performed at the Faculty of Dentistry of the Ondokuz Mayis University. The data were collected through a self-report questionnaire administered to dental students (137 female/111 male) in three different dental classes (third, fourth and fifth study years) and grouped by considering those students who have been training in the school year of 2013. The definition of physical and social indicators of abuse, awareness regarding legal and ethical responsibilities, students' experience and requests made by students were evaluated by the students' response to questions put in the questionnaire. Descriptive statistics and chi-square tests were performed to analyse the questionnaire data. The questionnaire completion rate was 100%. About 67.74% of the third year, 40.71% of the fourth year and 16.67% of the fifth year believed that they could detect child abuse cases. However, results indicated a major lack of knowledge of social indicators, signs of physical abuse and reporting procedure amongst all respondents. The assessment of the total correct answers exhibited significant differences amongst third-, fourth- and fifth-year students' answers. Fifth-year students had the highest rate of correct responses (P < 0.05). Most students wanted to receive more knowledge about this topic. Dental students in Turkey are not sufficiently prepared for their role in diagnosing suspected cases of child abuse. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Genetics, one of the core courses of biological field, play a key role in biology teaching and research. In fact, there exists high similarity between many genetic knowledge and physical knowledge. Due to strong abstract of genetic contents and the weak basis of genetics, some students lack of interests to study genetics. How to apply the strong physical knowledge which students had been learned in the middle school in genetics teaching is worthwhile for genetics teachers. In this paper, we would like to introduce an infiltrative teaching model on applying physical knowledge into genetic contents by establishing the intrinsic logistic relationship between physical knowledge and genetic knowledge. This teaching model could help students more deeply understand genetic knowledge and enhance students' self-studying ability as well as creating ability.

The lack of knowledge about the voluntary reporting system of adverse drug reactions as a major cause of underreporting: direct survey among health professionals.

Pérez García, Mariley; Figueras, Albert

2011-12-01

Underreporting suspected adverse drug reactions (ADRs) is one of the main problems that face the pharmacovigilance (PhV) systems based on yellow card schemes. To measure the knowledge level on the suspected ADR voluntary reporting system among physicians and pharmacists in Venezuela and to study its relationship with different variables. A population-based, anonymous, and self-administered questionnaire was addressed to health professionals along the national territory of Venezuela. An algorithm was developed to classify the knowledge level on the voluntary reporting system. Taken as a whole, the level of knowledge on the voluntary reporting system was "poor." Among the 515 participant physicians, 62.3% (95%CI = 58.0-66.5%) had a "poor" level of knowledge; PhV was associated with "control" of medicines use, and only 24.7% had ever reported a suspected ADR. "Medical specialty" was the only variable that showed a relationship with the knowledge level (p = 0.0041). Among the 78 participant pharmacists, 66.7% had a "poor" knowledge level (95%CI = 55.1-76.9%). The knowledge level on the voluntary reporting system among physicians and pharmacists in Venezuela is poor. These results strengthen the hypothesis that being unaware of the adverse effects of medicines and not knowing the existence of a PhV system is a major cause of underreporting. A careful study of the actual knowledge of PhV could be the basis to set up interventions specifically designed to overcome misleading concepts and to improve the reporting rate at a national level.

Entrepreneurship by any other name: self-sufficiency versus innovation.

Parker Harris, Sarah; Caldwell, Kate; Renko, Maija

Entrepreneurship has been promoted as an innovative strategy to address the employment of people with disabilities. Research has predominantly focused on the self-sufficiency aspect without fully integrating entrepreneurship literature in the areas of theory, systems change, and demonstration projects. Subsequently there are gaps in services, policies, and research in this field that, in turn, have limited our understanding of the support needs and barriers or facilitators of entrepreneurs with disabilities. A thorough analysis of the literature in these areas led to the development of two core concepts that need to be addressed in integrating entrepreneurship into disability employment research and policy: clarity in operational definitions and better disability statistics and outcome measures. This article interrogates existing research and policy efforts in this regard to argue for a necessary shift in the field from focusing on entrepreneurship as self-sufficiency to understanding entrepreneurship as innovation.

Despite widespread availability of assistive technology and the role of occupational therapists and audiologists in workplace health, little is known about how these groups influence the health of workers with hearing loss. Based on a previously conducted study, this paper explores the need for networking and community of practice theory to promote knowledge sharing and use between occupational therapists, audiologists, educators, regulators, workers, and employers. Five occupational therapists and five audiologists participated in in-depth interviews. Grounded theory was used to investigate the processes that hinder or support these professionals in addressing the accommodation needs of and workplace accessibility for workers with hearing loss. Constraints to addressing the needs of workers with hearing loss included: lack of knowledge about professional practice processes, lack of networking, lack of knowledge on current research, and lack of knowledge on the realm of expertise of audiologists by occupational therapists and of occupational therapists by audiologists. Innovations in workplace practice in hearing loss require engagement of occupational therapists, audiologists, and employers in knowledge transfer, networking, and learning. This column introduces two theories that may guide the use and development of evidence, knowledge, and expertise toward innovations in hearing work practice.

New infections of Human Immunodeficiency Virus (HIV) remain a big problem in many countries. Different interventions have been implemented to improve the general knowledge of HIV, with the hypothesis that increasing HIV knowledge will reduce risky sexual behavior (RSB). However, HIV knowledge may not necessarily reduce RSB. This study explores HIV knowledge and its effect on RSB. The study used data from the 2005 and 2010 Rwanda Demographic and Health Surveys to analyze the association between HIV risk factors and two types of RSB (having two or more partners in the past 12 months; and among those with two or more partners, not using a condom at last sex) and the association between HIV knowledge and those RSB. Multivariate logistic regression was used to determine predictors of RSB. Among 2,773 men in 2005 and 3,772 men in 2010, 5% and 7% respectively reported having two or more sexual partners. Among them, 93% in 2005 and 74% in 2010 did not use a condom at the last sex. Between 2005 and 2010, knowledge of the protective effect of having just one uninfected faithful partner, and basic knowledge of HIV decreased. Knowledge of the protective effect of using condoms increased from 90% to 94%. However, HIV knowledge was not associated with either type of RSB. In setting up policies and strategies related to HIV prevention, policymakers should consider that focusing on HIV knowledge is not sufficient in itself.

2016-12-01

Planetary Defense, a project funded by NASA Goddard and the NSF, is a multi-faceted effort focused on the mitigation of Near Earth Object (NEO) threats to our planet. Currently, there exists a dispersion of information concerning NEO's amongst different organizations and scientists, leading to a lack of a coherent system of information to be used for efficient NEO mitigation. In this paper, a planetary defense knowledge discovery engine is proposed to better assist the development and integration of a NEO responding system. Specifically, we have implemented an organized information framework by two means: 1) the development of a semantic knowledge base, which provides a structure for relevant information. It has been developed by the implementation of web crawling and natural language processing techniques, which allows us to collect and store the most relevant structured information on a regular basis. 2) the development of a knowledge discovery engine, which allows for the efficient retrieval of information from our knowledge base. The knowledge discovery engine has been built on the top of Elasticsearch, an open source full-text search engine, as well as cutting-edge machine learning ranking and recommendation algorithms. This proposed framework is expected to advance the knowledge discovery and innovation in planetary science domain.

The purpose of this study is to examine the following research questions in Turkish coaching context: a) What are coaches’ perceptions on the application of sport science research to their coaching methods? b) What sources do coaches utilize to obtain the knowledge they need? c) What barriers do coaches encounter when trying to access and apply the knowledge they need for their sport? In addition, differences in research questions responses were examined based on gender, years of coaching experience, academic educational level, coaching certificate level, coaching team or individual sports, and being paid or unpaid for coaching. The participants were 321 coaches (255 men, 66 women) from diverse sports and coaching levels working in Ankara. The questionnaire “New Ideas for Coaches” by Reade, Rodgers and Hall (2008) was translated, adapted into Turkish, and validated for the current study. According to our findings among Turkish coaches, there is a high prevalence of beliefs that sport science contributes to sport (79.8%);however, there are gaps between what coaches are looking for and the research that is being conducted. Coaches are most likely to attend seminars or consult other coaches to get new information. Scientific publications were ranked very low by the coaches in getting current information. The barriers to coaches’ access to sport science research are finding out the sources of information, being able to implement the sport science knowledge into the field of coaching, lack of monetary support in acquiring knowledge, and language barriers. Also, differences in perceptions and preferences for obtaining new information were identified based on coaches’ gender, coaching contexts (i.e., professional-amateur), coaching settings (i.e., team/individual), and their other demographic characteristics (i.e., coaching experience, coaching educational level, and coaching certificate level).

Integration of expert knowledge and uncertainty in natural risk assessment

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

This study investigates secondary teachers’ belief about the three mathematics-related beliefs, i.e. nature of mathematics, teaching mathematics, learning mathematics, and knowledge about mathematical problem solving. Data were gathered through a set of task-based semi-structured interviews of three selected teachers with different philosophical views of teaching mathematics, i.e. instrumental, platonist, and problem solving. Those teachers were selected from an interview using a belief-related task from purposively selected teachers in Surabaya and Sidoarjo. While the interviews about knowledge examine teachers’ problem solving content and pedagogical knowledge, the interviews about beliefs examine their views on several cases extracted from each of such mathematics-related beliefs. Analysis included the categorization and comparison on each of beliefs and knowledge as well as their interaction. Results indicate that all the teachers did not show a high consistency in responding views of their mathematics-related beliefs, while they showed weaknesses primarily on problem solving content knowledge. Findings also point out that teachers’ beliefs have a strong relationship with teachers’ knowledge about problem solving. In particular, the instrumental teacher’s beliefs were consistent with his insufficient knowledge about problem-solving, while both platonist and problem-solving teacher’s beliefs were consistent with their sufficient knowledge of either content or pedagogical problem solving.

Tajudin, Nor'ain Mohd; Chinnappan, Mohan; Saad, Noor Shah

2017-05-01

Two key variables emerged from the literature review is that Specific Matter Knowledge [SMK] and Pedagogical Content Knowledge [PCK] can influence the mathematics teachers' Professional Development [PD] needs. However, the key variables of SMK and PCK that were being investigated were not defined clearly. Empirical evidence that support relationship between SMK and PD and PCK and PD were not verified. In addition, how does PCK mediate SMK and PD is not clear and somewhat lacking. Therefore, the purpose of this paper was to examine the relationship between primary mathematics teacher's SMK, PCK and PD needs. Results of path analysis with SmartPLS indicated that the direct effect of SMK on PD was mediated via PCK. This data provide support for the claim that PD programs for future teachers of primary mathematics should be driven by a more nuanced understanding of the link between SMK and PCK.

The Kingdom of Saudi Arabia is experiencing a dramatic increase in physical inactivity, with women having higher levels of inactivity than men among all age groups. It is assumed that factors such as dress codes, restrictions on going outdoors, and conservative norms are the main reasons for women's low physical activity. Our aim was to explore the different parameters related to physical activity, including self-efficacy, as well as the perceived barriers to and benefits of physical activity in young Saudi females. Ninety-four first-year female Saudi university students in Riyadh, Kingdom of Saudi Arabia, participated in the present study in 2014. The students were from eight bachelor's programs in health and well-being, and each completed a questionnaire with questions divided into five parts as follows: 1) socioeconomic status, 2) physical activity, 3) self-efficacy 4) social factors, and 5) barriers and facilitators related to physical activity. The students exercised at home and alone, and there was low self-efficacy for physical activity (mean score =42±14). Among social factors, attending university was the only factor that hindered physical activity (32%). Physical activity was positively perceived overall (mean score =131±10). Students showed awareness of the benefits of physical activity for health and well-being. The most important barrier was the lack of designated areas available for physical activity. Students disagreed that family or the Islamic community were barriers to physical activity. The lack of facilities and lack of encouragement from the university, but not a lack of knowledge (a high level of knowledge is to be expected given their health and well-being studies backgrounds) and/or restrictions from families and society, seem to hinder female students' physical activity, at least young Saudi students.

"Lack of energy" or anergia is a common complaint associated with adverse outcomes in older people. There is a lack of knowledge on this symptom in the nursing home (NH) setting. The aim of this study was to investigate whether lack of energy was associated with hospitalization and mortality in NH residents. Longitudinal observational cohort study. A total of 575 NH residents (72% women) in 13 French NHs from the Incidence of pNeumonia and related ConseqUences in nursing home Residents (INCUR) study cohort. Lack of energy was measured at the baseline visit as part of the 10-item Geriatric Depression Scale. Unadjusted and adjusted Cox proportional hazard regression models were performed to test the association of lack of energy with hospitalization events and mortality over 12 months of follow-up. The mean age of the study sample was 86.3 (SD = 7.5) years. At the baseline, 250 (43.5%) residents complained about lack of energy. Overall, 192 (33.4%) individuals experienced at least 1 hospitalization event and 98 (17.0%) died during the 12-month follow-up. Lack of energy was significantly associated with a higher risk of hospitalization (HR 1.35; 95% CI 1.02-1.80; P = .03), even after adjustment for potential confounders (HR 1.41; 95% CI 1.04-1.91; P = .02). No statistically significant association was found between lack of energy and 12-month mortality. Lack of energy is a predictor of hospitalization in older people living in NHs. It may be considered a relevant clinical feature for identifying individuals at risk of adverse health outcomes, thus potentially serving as a screening tool for subsequently conducting a comprehensive geriatric assessment in this highly vulnerable and complex population.

2011-05-01

Roughly one-fifth of the US population displays one or more symptoms of dyslexia: a specific learning disability that affects an individual's ability to process written language. Consequently, elementary school teachers are teaching students who struggle with inaccurate or slow reading, poor spelling, poor writing, and other language processing difficulties. Findings from studies have indicated that teachers lack essential knowledge needed to teach struggling readers, particularly children with dyslexia. However, few studies have sought to assess teachers' knowledge and perceptions about dyslexia in conjunction with knowledge of basic language concepts related to reading instruction. Thus, the purpose of the present study was to examine elementary school teachers' knowledge of basic language concepts and their knowledge and perceptions about dyslexia. Findings from the present study indicated that teachers, on average, were able to display implicit skills related to certain basic language concepts (i.e. syllable counting), but failed to demonstrate explicit knowledge of others (i.e. phonics principles). Also, teachers seemed to hold the common misconception that dyslexia is a visual processing deficit rather than phonological processing deficit. Copyright © 2011 John Wiley & Sons, Ltd.

Lack of knowledge is one of the main reasons for the low rates of completion of Advance Care Planning (ACP). The purpose of this study was to systematically review the existing literature on knowledge regarding Advance Care Planning. A systematic search of the literature was made in CINHAL, AgeLine, PubMed, PsyINFO and SocINDEX, from 1994 till May 2016. We identified 37 articles that satisfied the inclusion criteria: 35 were quantitative, one was qualitative and one used mixed methods. Most of the studies (n=23) were conducted in the United States and participants in most of the studies (n=22) were professionals. A variety of aspects of ACP were examined, regarding subjective and objective knowledge. Seventeen studies found that participants knew some aspects of ACP, but didn't know others. Inconsistencies were found in the types of instruments and the number of items used to assess knowledge. More effort should be invested in increasing knowledge regarding ACP among professionals and lay people. Developing validated tools to measure objective and subjective knowledge in both populations might be a first step in this direction. Copyright © 2017 Elsevier B.V. All rights reserved.

Pressure ulcer prevention knowledge among Jordanian nurses: a cross- sectional study

PubMed Central

2014-01-01

Background Pressure ulcer remains a significant problem in the healthcare system. In addition to the suffering it causes patients, it bears a growing financial burden. Although pressure ulcer prevention and care have improved in recent years, pressure ulcer still exists and occurs in both hospital and community settings. In Jordan, there are a handful of studies on pressure ulcer. This study aims to explore levels of knowledge and knowledge sources about pressure ulcer prevention, as well as barriers to implementing pressure ulcer prevention guidelines among Jordanian nurses. Methods Using a cross-sectional study design and a self-administered questionnaire, data was collected from 194 baccalaureate and master’s level staff nurses working in eight Jordanian hospitals. From September to October of 2011, their knowledge levels about pressure ulcer prevention and the sources of this knowledge were assessed, along with the barriers which reduce successful pressure ulcer care and prevention. ANOVA and t-test analysis were used to test the differences in nurses’ knowledge according to participants’ characteristics. Means, standard deviation, and frequencies were used to describe nurses’ knowledge levels, knowledge sources, and barriers to pressure ulcer prevention. Results The majority (73%, n = 141) of nurses had inadequate knowledge about pressure ulcer prevention. The mean scores of the test for all participants was 10.84 out of 26 (SD = 2.3, range = 5–17), with the lowest score in themes related to PU etiology, preventive measures to reduce amount of pressure/shear, and risk assessment. In-service training was the second source of education on pressure ulcer, coming after university training. Shortage of staff and lack of time were the most frequently cited barriers to carrying out pressure ulcer risk assessment, documentation, and prevention. Conclusions This study highlights concerns about Jordanian nurses’ knowledge of pressure ulcer prevention. The

2010-01-01

The purpose of this study was to explore the relationship among nurses'perceived burn prevention knowledge, their perceived ability to teach about burn prevention, and their actual burn prevention knowledge and to test if their actual burn knowledge could be predicted by these perceived measures. A two-page, anonymous survey that included a 10-item burn prevention knowledge test and an assessment of nurses'perceived knowledge of burn prevention and their perceived ability to teach burn prevention was administered to 313 nurses. Actual burn prevention knowledge was determined and the correlation among actual burn prevention knowledge, perceived knowledge, and perceived ability to teach was determined. Differences in these outcome variables based on specialty area were tested using analysis of variance techniques. Generalized linear modeling techniques were used to investigate which variables significantly predict a nurse's actual burn prevention knowledge. Test for interaction effects were performed, and significance was set at .05. Responding nurses (N = 265) described practicing in a variety of settings, such as pediatric settings (40.2%, n = 105), emergency departments (25.4%, n = 86), medical/surgical settings (8.4%, n = 22), and one pediatric burn setting (4.1%, n = 14), with all specialty areas as having similar actual burn prevention knowledge (P = .052). Seventy-seven percent of the nurses said they never taught about burn prevention (n = 177). Perceived knowledge and actual knowledge (r = .124, P = .046) as well as perceived knowledge and perceived ability were correlated (r = .799, P < .001). Significant predictors of actual knowledge were years in practice (beta = -0.063, P = .034), years in current area (beta = 0.072, P = .003), perceived knowledge (beta = 0.109, P = .042), and perceived ability (beta = 0.137, P = .019). All nurses, regardless of specialty area, have poor burn prevention knowledge, which is correlated with their perceived lack of

Knowledge, perceptions, and behaviors of adults concerning nonalcoholic beverages suggest some lack of comprehension related to sugars.

Rampersaud, Gail C; Kim, Hyeyoung; Gao, Zhifeng; House, Lisa A

2014-02-01

Key recommendations in the 2010 Dietary Guidelines for Americans and US Department of Agriculture's MyPlate are to reduce the intake of added sugars, particularly from sugar-sweetened beverages, and drink water instead of "sugary" beverages. However, little is known about consumer knowledge, perceptions, and behaviors regarding sugars in beverages. We hypothesized that consumers would have limited or inaccurate knowledge of the sugars in beverages and that their beverage consumption behaviors would not reflect their primary concerns related to sugars in beverages. An online survey was completed by 3361 adults 18 years and older residing throughout the United States. Water was consumed in the highest amounts followed by (in descending amounts) other beverages (includes coffee and tea), added sugar beverages, milk, diet drinks, and 100% fruit juice and blends. Participants primarily associated the term "sugary" with beverages containing added sugars; however, almost 40% identified 100% fruit juice as sugary. Some participants misidentified the types of sugars in beverages, particularly with respect to milk and 100% fruit juices. Generally, beverage choices were consistent with stated concerns about total, added, or natural sugars; however, less than 40% of participants identified added sugars as a primary concern when choosing beverages despite public health recommendations to reduce the intake of added sugars and sugar-sweetened beverages. Results suggest that there may be a considerable level of consumer misunderstanding or confusion about the types of sugars in beverages. More consumer research and education are needed with the goal of helping consumers make more informed and healthy beverage choices. Copyright © 2014 Elsevier Inc. All rights reserved.

Knowledge Engineering for Preservation and Future use of Institutional Knowledge

Moreman, Douglas; Dyer, John

1996-01-01

This Project has two main thrusts-preservation of special knowledge and its useful representation via computers. NASA is losing the expertise of its engineers and scientists who put together the great missions of the past. We no longer are landing men on the moon. Some of the equipment still used today (such as the RL-10 rocket) was designed decades ago by people who are now retiring. Furthermore, there has been a lack, in some areas of technology, of new projects that overlap with the old and that would have provided opportunities for monitoring by senior engineers of the young ones. We are studying this problem and trying out a couple of methods of soliciting and recording rare knowledge from experts. One method is that of Concept Maps which produces a graphical interface to knowledge even as it helps solicit that knowledge. We arranged for experienced help in this method from John Coffey of the Institute of Human and Machine Technology at the University of West Florida. A second method which we plan to try out in May, is a video-taped review of selected failed missions (e.g., the craft tumbled and blew up). Five senior engineers (most already retired from NASA) will, as a team, analyze available data, illustrating their thought processes as they try to solve the problem of why a space craft failed to complete its mission. The session will be captured in high quality audio and with at least two video cameras. The video can later be used to plan future concept mapping interviews and, in edited form, be a product in itself. Our computer representations of the amassed knowledge may eventually, via the methods of expert systems, be joined with other software being prepared as a suite of tools to aid future engineers designing rocket engines. In addition to representation by multimedia concept maps, we plan to consider linking vast bodies of text (and other media) by hypertexting methods.

Assessing sufficient capability: A new approach to economic evaluation.

Mitchell, Paul Mark; Roberts, Tracy E; Barton, Pelham M; Coast, Joanna

2015-08-01

Amartya Sen's capability approach has been discussed widely in the health economics discipline. Although measures have been developed to assess capability in economic evaluation, there has been much less attention paid to the decision rules that might be applied alongside. Here, new methods, drawing on the multidimensional poverty and health economics literature, are developed for conducting economic evaluation within the capability approach and focusing on an objective of achieving "sufficient capability". This objective more closely reflects the concern with equity that pervades the capability approach and the method has the advantage of retaining the longitudinal aspect of estimating outcome that is associated with quality-adjusted life years (QALYs), whilst also drawing on notions of shortfall associated with assessments of poverty. Economic evaluation from this perspective is illustrated in an osteoarthritis patient group undergoing joint replacement, with capability wellbeing assessed using ICECAP-O. Recommendations for taking the sufficient capability approach forward are provided. Copyright © 2015 Elsevier Ltd. All rights reserved.

Competing Cues: Older Adults Rely on Knowledge in the Face of Fluency

Brashier, Nadia M.; Umanath, Sharda; Cabeza, Roberto; Marsh, Elizabeth J.

2017-01-01

Consumers regularly encounter repeated false claims in political and marketing campaigns, but very little empirical work addresses their impact among older adults. Repeated statements feel easier to process, and thus more truthful, than new ones (i.e., illusory truth). When judging truth, older adults’ accumulated general knowledge may offset this perception of fluency. In two experiments, participants read statements that contradicted information stored in memory; a post-experimental knowledge check confirmed what individual participants knew. Unlike young adults, older adults exhibited illusory truth only when they lacked knowledge about claims. This interaction between knowledge and fluency extends dual-process theories of aging.

High consumption of soft drinks has been associated with lower intakes of milk and calcium-rich foods and higher body mass index (BMI). This study aimed to explore the pattern of beverage intake among Kuwaiti high-school students. A questionnaire on knowledge, attitudes and practices concerning beverages and milk and dairy products intake was completed by 190 Kuwaiti students aged 16-18 years and BMI was calculated for 181 of them. Intake of sweetened carbonated beverages and to a lesser extent packaged fruit juices affected the sufficiency of milk and dairy products intake among the sample of high-school students in Kuwait. Although BMI was not related to milk and dairy insufficiency, more of the overweight and obese students displayed incorrect practices. Nutritional education of high-school students on the importance of milk and dairy products as well as the hazards of excess sweetened carbonated beverages and packaged juice is recommended to prevent the obesity epidemic prevailing in Kuwait.

2007-09-01

Nutritional therapy is an integral component of diabetes management. It's main goals are to attain and maintain normal blood glucose levels and to prevent and treat the chronic complication of diabetes. It is recommended that a registered dietitian will provide the dietary treatment but it is essential that all the medical team members will have the required and updated nutritional knowledge in order to support the patient in adopting a healthy life style. The purpose of this research was to assess nutritional knowledge and attitudes of physicians and nurses toward the dietary treatment of diabetic patients and to determine their involvement in the nutritional therapy. Out of 99 family physicians and nurses in the south district of Clalit Health Services who were approached by the researchers a total of 67, 34 physicians and 33 nurses, participated in this analysis and returned their completed questionnaires. The results indicate lack of knowledge towards nutritional therapy in diabetes with an average score of 48%. The average score (percent of correct answers) of physicians was significantly higher than the nurses (50.9% vs. 44.5% respectively p < 0.05). Both groups were aware of the purpose and importance of the nutritional therapy and how to integrate fruit in the patient's diet (91% vs. 92% respectively). Lack of knowledge was found in the area of dietary fat and diabetes, the definition of the glycemic index and in recognition of food containing carbohydrates/ mono-unsaturated fats. Nonetheless, physicians and nurses reported that they are involved in the nutritional therapy. Over 90% provide nutritional advice to diabetic patients regularly and 56% even prescribe a diet for them. On the one hand, these findings indicate lack of knowledge concerning the nutritional therapy in diabetes among family physicians and nurses but, on the other hand, there is also significant involvement of the health team in the treatment. We recommend an on-going nutritional

A Natural Language Interface Concordant with a Knowledge Base.

The discordance between expressions interpretable by a natural language interface (NLI) system and those answerable by a knowledge base is a critical problem in the field of NLIs. In order to solve this discordance problem, this paper proposes a method to translate natural language questions into formal queries that can be generated from a graph-based knowledge base. The proposed method considers a subgraph of a knowledge base as a formal query. Thus, all formal queries corresponding to a concept or a predicate in the knowledge base can be generated prior to query time and all possible natural language expressions corresponding to each formal query can also be collected in advance. A natural language expression has a one-to-one mapping with a formal query. Hence, a natural language question is translated into a formal query by matching the question with the most appropriate natural language expression. If the confidence of this matching is not sufficiently high the proposed method rejects the question and does not answer it. Multipredicate queries are processed by regarding them as a set of collected expressions. The experimental results show that the proposed method thoroughly handles answerable questions from the knowledge base and rejects unanswerable ones effectively.

Objective To determine and to analyze the theoretical and practical knowledge of Nursing professionals on indirect blood pressure measurement. Methods This cross-sectional study included 31 professionals of a coronary care unit (86% of the Nursing staff in the unit). Of these, 38.7% of professionals were nurses and 61.3% nurse technicians. A validated questionnaire was used to theoretical evaluation and for practice assessment the auscultatory technique was applied in a simulation environment, under a non-participant observation. Results To the theoretical knowledge of the stages of preparation of patient and environment, 12.9% mentioned 5-minute of rest, 48.4% checked calibration, and 29.0% chose adequate cuff width. A total of 64.5% of professionals avoided rounding values, and 22.6% mentioned the 6-month deadline period for the equipment calibration. On average, in practice assessment, 65% of the steps were followed. Lacks in knowledge were primary concerning lack of checking the device calibration and stethoscope, measurement of arm circumference to choose the cuff size, and the record of arm used in blood pressure measurement. Conclusion Knowledge was poor and had disparities between theory and practice with evidence of steps taken without proper awareness and lack of consideration of important knowledge during implementation of blood pressure measurement. Educational and operational interventions should be applied systematically with institutional involvement to ensure safe care with reliable values. PMID:25295455

Conditional loss of progranulin in neurons is not sufficient to cause neuronal ceroid lipofuscinosis-like neuropathology in mice.

PubMed

Petkau, Terri L; Blanco, Jake; Leavitt, Blair R

2017-10-01

Progranulin deficiency due to heterozygous null mutations in the GRN gene is a common cause of familial frontotemporal lobar degeneration (FTLD), while homozygous loss-of-function GRN mutations cause neuronal ceroid lipofuscinosis (NCL). Aged progranulin-knockout mice display highly exaggerated lipofuscinosis, microgliosis, and astrogliosis, as well as mild cell loss in specific brain regions. Progranulin is a secreted glycoprotein expressed in both neurons and microglia, but not astrocytes, in the brain. We generated conditional progranulin-knockout mice that lack progranulin in nestin-expressing cells (Nes-cKO mice), which include most neurons as well as astrocytes. We confirmed near complete knockout of progranulin in neurons in Nes-cKO mice, while microglial progranulin levels remained similar to that of wild-type animals. Overall brain progranulin levels were reduced by about 50% in Nes-cKO, and no Grn was detected in primary Nes-cKO neurons. Nes-cKO mice aged to 12months did not display any increase in lipofuscin deposition, microgliosis, or astrogliosis in the four brain regions examined, though increases were observed for most of these measures in Grn-null animals. We conclude that neuron-specific loss of progranulin is not sufficient to cause similar neuropathological changes to those seen in constitutive Grn-null animals. Our results suggest that increased lipofuscinosis and gliosis in Grn-null animals are not caused by intrinsic progranulin deficiency in neurons, and that microglia-derived progranulin may be sufficient to maintain neuronal health and homeostasis in the brain.

Greater learnability is not sufficient to produce cultural universals.

PubMed

Rafferty, Anna N; Griffiths, Thomas L; Ettlinger, Marc

2013-10-01

Looking across human societies reveals regularities in the languages that people speak and the concepts that they use. One explanation that has been proposed for these "cultural universals" is differences in the ease with which people learn particular languages and concepts. A difference in learnability means that languages and concepts possessing a particular property are more likely to be accurately transmitted from one generation of learners to the next. Intuitively, this difference could allow languages and concepts that are more learnable to become more prevalent after multiple generations of cultural transmission. If this is the case, the prevalence of languages and concepts with particular properties can be explained simply by demonstrating empirically that they are more learnable. We evaluate this argument using mathematical analysis and behavioral experiments. Specifically, we provide two counter-examples that show how greater learnability need not result in a property becoming prevalent. First, more learnable languages and concepts can nonetheless be less likely to be produced spontaneously as a result of transmission failures. We simulated cultural transmission in the laboratory to show that this can occur for memory of distinctive items: these items are more likely to be remembered, but not generated spontaneously once they have been forgotten. Second, when there are many languages or concepts that lack the more learnable property, sheer numbers can swamp the benefit produced by greater learnability. We demonstrate this using a second series of experiments involving artificial language learning. Both of these counter-examples show that simply finding a learnability bias experimentally is not sufficient to explain why a particular property is prevalent in the languages or concepts used in human societies: explanations for cultural universals based on cultural transmission need to consider the full set of hypotheses a learner could entertain and all of

An object-relational model for structured representation of medical knowledge.

Koch, S; Risch, T; Schneider, W; Wagner, I V

2006-07-01

Domain specific knowledge is often not static but continuously evolving. This is especially true for the medical domain. Furthermore, the lack of standardized structures for presenting knowledge makes it difficult or often impossible to assess new knowledge in the context of existing knowledge. Possibilities to compare knowledge easily and directly are often not given. It is therefore of utmost importance to create a model that allows for comparability, consistency and quality assurance of medical knowledge in specific work situations. For this purpose, we have designed on object-relational model based on structured knowledge elements that are dynamically reusable by different multi-media-based tools for case-based documentation, disease course simulation, and decision support. With this model, high-level components, such as patient case reports or simulations of the course of a disease, and low-level components (e.g., diagnoses, symptoms or treatments) as well as the relationships between these components are modeled. The resulting schema has been implemented in AMOS II, on object-relational multi-database system supporting different views with regard to search and analysis depending on different work situations.

Role of L-alanine for redox self-sufficient amination of alcohols.

PubMed

Klatte, Stephanie; Wendisch, Volker F

2015-01-23

In white biotechnology biocatalysis represents a key technology for chemical functionalization of non-natural compounds. The plasmid-born overproduction of an alcohol dehydrogenase, an L-alanine-dependent transaminase and an alanine dehydrogenase allows for redox self-sufficient amination of alcohols in whole cell biotransformation. Here, conditions to optimize the whole cell biocatalyst presented in (Bioorg Med Chem 22:5578-5585, 2014), and the role of L-alanine for efficient amine functionalization of 1,10-decanediol to 1,10-diaminodecane were analyzed. The enzymes of the cascade for amine functionalization of alcohols were characterized in vitro to find optimal conditions for an efficient process. Transaminase from Chromobacterium violaceum, TaCv, showed three-fold higher catalytic efficiency than transaminase from Vibrio fluvialis, TaVf, and improved production at 37°C. At 42°C, TaCv was more active, which matched thermostable alcohol dehydrogenase and alanine dehydrogenase and improved the 1,10-diaminodecane production rate four-fold. To study the role of L-alanine in the whole cell biotransformation, the L-alanine concentration was varied and 1,10.diaminodecane formation tested with constant 10 mM 1,10- decanediol and 100 mM NH4Cl. Only 5.6% diamine product were observed without added L-alanine. L-alanine concentrations equimolar to that of the alcohol enabled for 94% product formation but higher L-alanine concentrations allowed for 100% product formation. L-alanine was consumed by the E. coli biocatalyst, presumably due to pyruvate catabolism since up to 16 mM acetate accumulated. Biotransformation employing E. coli strain YYC202/pTrc99a-ald-adh-ta Cv, which is unable to catabolize pyruvate, resulted in conversion with a selectivity of 42 mol-%. Biotransformation with E. coli strains only lacking pyruvate oxidase PoxB showed similar reduced amination of 1,10-decanediol indicating that oxidative decarboxylation of pyruvate to acetate by PoxB is primarily

Vitamin status and bone strength have been estimated in 91 pregnant women (29.3 ± 4.6 years old) from Moscow by non-invasive methods. Sufficiency with vitamins C, B2, B6 has been evaluated by morning urinary excretion of ascorbic acid, riboflavin and 4-piridoxic acid determined by visual titration and fluorimetric methods. The rate of bone resorption has been measured by the ratio of urinary calcium and creatinine, determined by complexometric titration and spectrophotometrically. The study of the bone strength has been conducted using an ultrasonic densitometer (the speed of the ultrasonic waves along the cortical layer). The lack of vitamin C was found in 20.4% .of the women surveyed, vitamin B2--in 27.4%. Vitamin B6 deficiency was detected most frequently (90%). Excretion of vitamins B2 and B6 in women in the third trimester of pregnancy was lower as compared with the women in the first and second trimester. In 53.3% of the women surveyed an increase in urinary excretion of calcium per creatinine has been observed. Excretion of group B vitamins (especially vitamin B6, 1.75 fold, p < 0.05) in women taking vitamin supplements was higher compared to non-taking vitamins that indicates the better sufficiency of the organism with these vitamins. Among women who took vitamin complexes, inadequate supply with water-soluble vitamins C, B2 and B6 was detected less frequently (the difference was significant for vitamin B2) than among women who did not intake vitamin complexes (in 11.9, 27.7 and 42.4% vs 16.1, 54.8 and 48.8 %). The rate of bone resorption (Ca/creatinine) in women taking vitamins was smaller (0.19 ± 0.09 vs 0.24 ± 0.14, p > 0.05). Ca/creatinine ratio was within normal range in 40% of women who intake vitamins, while in women not taking vitamins--only in 22.2%; this value exceeded the upper limit of norm in the rest. The strength of bone was broken in women in the second and third trimester of pregnancy, having worse supply of vitamins. The percentage of

We wanted to develop and validate a test that assesses the knowledge and practices of health professionals (HPs) with regard to the role of nutrition, physical activity, and smoking cessation (lifestyle modification) in chronic diseases of lifestyle. A descriptive cross-sectional validation study was carried out. The validation design consisted of two phases, namely 1) test planning and development and 2) test evaluation. The study sample consisted of five groups of HPs: dietitians, dietetic interns, general practitioners, medical students, and nurses. The overall response rate was 58%, resulting in a sample size of 186 participants. A test was designed to evaluate the knowledge and practices of HPs. The test was first evaluated by an expert group to ensure content, construct, and face validity. Thereafter, the questionnaire was tested on five groups of HPs to test for criterion validity. Internal consistency was evaluated by Cronbach's alpha. An expert panel ensured content, construct, and face validity of the test. Groups with the most training and exposure to nutrition (dietitians and dietetic interns) had the highest group mean score, ranging from 61% to 88%, whereas those with limited nutrition training (general practitioners, medical students, and nurses) had significantly lower scores, ranging from 26% to 80%. This result demonstrated criterion validity. Internal consistency of the overall test demonstrated a Cronbach's alpha of 0.99. Most HPs identified the mass media as their main source of information on lifestyle modification. These HPs also identified lack of time, lack of patient compliance, and lack of knowledge as barriers that prevent them from providing counseling on lifestyle modification. The results of this study showed that this test instrument identifies groups of health professionals with adequate training (knowledge) in lifestyle modification and those who require further training (knowledge).

Anaphylaxis: lack of hospital doctors' knowledge of adrenaline (epinephrine) administration in adults could endanger patients' safety.

Droste, J; Narayan, N

2012-06-01

Adrenaline (epinephrine) is the first line drug to be given in anaphylaxis and can save patients' lives. Conversely, incorrect administration of adrenaline in anaphylaxis has caused patients serious harm, including death. We compared the survey results of doctors' knowledge of adrenaline administration in adults of two District General Hospitals Trusts in England and found, that from 284 Hospital Doctors, 14.4% (n = 41) would administer adrenaline as recommended by published anaphylaxis guidelines. This survey comparison shows that a significant number of hospital doctors, regardless of seniority and specialty, have an educational deficit regarding correct administration of adrenaline (epinephrine) administration in adults with anaphylaxis. Multilevel strategies to educate doctors and prevent patient harm are needed. We propose a mnemonic for remembering the recommended treatment for anaphylaxis in the adult: "A Thigh 500" forAdrenaline into the antero-lateral thigh, 500 micrograms.

This study assessed cancer knowledge, beliefs, and awareness of signs, symptoms, and early detection methods in immigrant Salvadorean women in the Washington, D.C. metropolitan area (DCMA). A face-to-face survey sampled 843 females aged 20 and above. Descriptive statistics were used to compute frequency of response for sociodemographic characteristics, beliefs, and awareness of signs, symptoms, and early detection methods. The sample's mean age was 34.5 years; 10% had no schooling, and 7.4% had more than a high school education. Sixty-six percent of the women worked full- or part-time; 16% had an annual income of $20,000 or more; and 26% reported having medical insurance. Thirty percent of the sample lacked knowledge of the etiology and spread of cancer. The statement, "Bumps on your body can cause cancer" was endorsed by 61.6%. Beliefs that "destiny cannot be changed" or "just about anything can cause cancer" were prevalent among 18.5%. "Cancer is a punishment from God" was believed by 10.9%. A general physical examination was the most frequent (82%) early detection method mentioned. The Pap test was identified by 24.2%, and mammography by 14%; 5.6% mentioned breast self examination. Similar to other Hispanics, immigrant Salvadorean women in DCMA demonstrated a lack of knowledge of cancer's signs and symptoms, and early detection methods of and beliefs about cancer. Educational programs designed specifically for immigrant Salvadorean women to increase their knowledge of cancer and prevention methods are essential.

Low levels of glutathione are sufficient for survival of keratinocytes after UV irradiation and for healing of mouse skin wounds.

Telorack, Michèle; Abplanalp, Jeannette; Werner, Sabine

2016-08-01

Reduced levels of the cellular antioxidant glutathione are associated with premature skin aging, cancer and impaired wound healing, but the in vivo functions of glutathione in the skin remain largely unknown. Therefore, we analyzed mice lacking the modifier subunit of the glutamate cysteine ligase (Gclm), the enzyme that catalyzes the rate-limiting step of glutathione biosynthesis. Glutathione levels in the skin of these mice were reduced by 70 %. However, neither skin development and homeostasis, nor UVA- or UVB-induced apoptosis in the epidermis were affected. Histomorphometric analysis of excisional wounds did not reveal wound healing abnormalities in young Gclm-deficient mice, while the area of hyperproliferative epithelium as well as keratinocyte proliferation were affected in aged mice. These findings suggest that low levels of glutathione are sufficient for wound repair in young mice, but become rate-limiting upon aging.

Informed consent: information or knowledge?

PubMed

Berger, Ken

2003-01-01

A fiduciary relationship should be nurtured between patient and physician. This requires effective communication throughout all aspects of care - especially pertaining to treatment decisions. In the context of illness as experienced by the patient a unique set of circumstances is presented. However, communication in an illness context is fraught with problems. The patient is vulnerable and the situation may be overwhelming. Voluminous amounts of information are available to patients from a host of health care providers, family members, support groups, advocacy centers, books, journals, and the internet. Often conflicting and confusion, frequently complex, this information may be of greater burden than benefit. Some information is of high validity and reliability while other information is of dubious reliability. The emotional freight of bad news may further inhibit understanding. An overload of information may pose an obstacle in decision-making. To facilitate the transformation of information into knowledge, the health care provider must act on some occasions as a filter, on other occasions as a conduit, and on still other occasions simply as a reservoir. The evolution of patient rights to receive or refuse treatment, the right to know or not to know calls for a change in processing of overwhelming information in our modem era. In this paper we will discuss the difference between information and knowledge. How can health care providers ensure they have given their patients all necessary and sufficient information to make an autonomous decision? How can they facilitate the transformation of information into knowledge? The effect of knowledge to consent allows a more focused, relevant and modern approach to choice in health care.

Demystifying knowledge translation: learning from the community.

PubMed

Bowen, Sarah; Martens, Patricia

2005-10-01

While there is increasing interest in research related to so-called Knowledge Translation, much of this research is undertaken from the perspective of researchers. The objective of this paper is to explore, through the participatory evaluation of Manitoba's The Need to Know Project, the characteristics of effective knowledge translation initiatives from the perspective of community partners. The multi-method evaluation adopted a utilization-focused approach, where stakeholders participated in identifying evaluation questions, and methods were made transparent to participants. Over 100 open-ended, semi-structured interviews were conducted with project stakeholders over the first three years of the project. These interviews explored the perspectives of participants on all aspects of project development. Formal feedback processes allowed further refinement of emerging theory. This research suggests that there has been insufficient emphasis on personal factors in knowledge translation. The themes of 'quality of relationships' and 'trust' connected many different components of knowledge translation, and were essential for collaborative research. Organizational barriers and lack of confidence in researchers present greater challenges to knowledge translation than individual interest or community capacity. The costs of participation in collaborative research for community partners and the benefits for researchers, also require greater attention. Participation of community partners in The Need to Know Project has provided unique perspectives on knowledge translation theory. It has identified limitations to the common interpretations of knowledge translation principles and highlighted the characteristics of collaborative research initiatives that are of greatest importance to community partners.

District nurses' knowledge development in wound management: ongoing learning without organizational support.

2014-10-01

The aim of this study was to describe district nurses' (DNs') experiences of their knowledge development in wound management when treating patients with different types of wounds at healthcare centers. In primary healthcare, DNs are mainly responsible for wound management. Previous research has focused on DNs' level of expertise regarding wound management, mostly based on quantitative studies. An unanswered question concerns DNs' knowledge development in wound management. The present study therefore intends to broaden understanding and to provide deeper knowledge in regard to the DNs' experiences of their knowledge development when treating patients with wounds. A qualitative descriptive design was used. Subjects were a purposeful sample of 16 DNs from eight healthcare centers in a metropolitan area in Stockholm, Sweden. The study was conducted with qualitative interviews and qualitative content analysis was used to analyze the data. The content analysis resulted in three categories and 11 sub-categories. The first category, 'ongoing learning by experience,' was based on experiences of learning alongside clinical practice. The second category 'searching for information,' consisted of various channels for obtaining information. The third category, 'lacking organizational support,' consisted of experiences related to the DNs' work organization, which hindered their development in wound care knowledge. The DNs experienced that they were in a constant state of learning and obtained their wound care knowledge to a great extent through practical work, from their colleagues as well as from various companies. A lack of organizational structures and support from staff management made it difficult for DNs to develop their knowledge and skills in wound management, which can lead to inadequate wound management.

Lack of knowledge and awareness about oral cancer, its risk factors and negligence of the early warning signs play crucial role in raising the incidence of the disease. The present study was carried out to evaluate the awareness of oral cancer among patients visiting Kantipur Dental College, Kathmandu, Nepal. The cross-sectional study was done in 471 patients from 15-85 years. Self administered questionnaire was prepared which comprised of knowledge of oral cancer, source of information, its early signs and symptoms along with the awareness of its risk factors. Most of the participants (41.80%) had not heard of oral cancer. 31.60% recognized tobacco smoking and tobacco chewing as the chief risk factor with 15.50% and 10.80% of participants who identified white patch and red patch as early sign of oral cancer respectively. Pearson's chi square test was used which showed statistically significant association of total mean knowledge score and awareness score with age, education level and occupation (p<0.05). This study done in dental patients showed lack of knowledge and awareness in general public about oral cancer. There seem to be a need for more planned awareness programs through newspapers, radio, television and health campaigns regarding the association of habits in the development of oral cancer and benefits of detecting oral cancer at early stage for better prognosis.

In South Africa, availability of antiretroviral (ARV) drugs has increased largely in the public sector since it became available in 2004. Follow-up of stabilized patients on ARV drugs are done in primary health care (PHC) facilities run by nurses, often without specialized training. This has deep impact on the patients' drug adherence. To investigate health care providers' (HCPs) knowledge about human immunodeficiency virus (HIV) and antiretroviral therapy (ART) in the Eastern Cape Province, South Africa. The aim was also to investigate nurses' knowledge and experience regarding adverse drug reaction (ADR) reporting. Public PHC clinics in one district of the Eastern Cape Province. Personal interviews, using a structured questionnaire, were conducted with 102 HCPs (nurses and auxiliary staff) working at six PHC facilities, one community health centre and one health post. Knowledge about HIV and ART among nurses and auxiliary staff. Both nurses and auxiliary staff had some basic knowledge about symptoms of HIV and modes of transmission, but great uncertainty was seen regarding specific topics including ARV drugs, ADRs and HIV complications. The PHC staff were uncertain about how to administer ARV drugs--with or without food--and some of them would advice their patients not to take ARV drugs at times when food was lacking. Both nurses and auxiliary staff knew that HIV was treated with ARV drugs. Only 60 % of the HCPs claimed that ART was the only effective treatment for HIV, whereas 39 % claimed that nutritious food also could treat HIV. Nurses showed lacking ability to manage ADRs. They also had very little knowledge about ADR reporting, and very few had ever submitted a report at all. The study shows that both nurses and auxiliary staff are unable to provide the patients with adequate advice about administration of the ARV drugs and management of ADRs. Serious lack of knowledge among HCPs regarding the treatment of HIV presents structural barriers to the patients

This paper demonstrates how knowledge can be extracted from evolving spiking neural networks with rank order population coding. Knowledge discovery is a very important feature of intelligent systems. Yet, a disproportionally small amount of research is centered on the issue of knowledge extraction from spiking neural networks which are considered to be the third generation of artificial neural networks. The lack of knowledge representation compatibility is becoming a major detriment to end users of these networks. We show that a high-level knowledge can be obtained from evolving spiking neural networks. More specifically, we propose a method for fuzzy rule extraction from an evolving spiking network with rank order population coding. The proposed method was used for knowledge discovery on two benchmark taste recognition problems where the knowledge learnt by an evolving spiking neural network was extracted in the form of zero-order Takagi-Sugeno fuzzy IF-THEN rules.

Fluoroscopy is frequently used in orthopaedic surgery, particularly in a trauma setting. Exposure of patients and staff to ionising radiation has been studied extensively; however, little work has been done to evaluate current knowledge and practices among orthopaedic trainees. This study aimed to investigate the knowledge and practices of Irish orthopaedic trainees regarding use of ionising radiation. A confidential internet-based survey on workplace radiation safety practices was distributed via email to 40 higher specialist trainees. Questions included related to radiation safety training and regular work practices. A total of 26 trainees completed the questionnaire (65% response rate). All reported regular exposure to ionising radiation. Compliance with body shields was high (25, 96%), however, other protective measures such as thyroid shields were less frequently employed. The 'as low as reasonably achievable principle' was practised regularly by 14 (54%). Radiation safety training was variable-while just over half (14) respondents felt adequately trained in radiation safety, 17 (65%) had attended a radiation protection course. Use of dosimeters was particularly poor, with only 4 (15%) using them regularly and most citing lack of availability as the main barrier. Although most Irish orthopaedic trainees have some knowledge regarding radiation safety, many do not regularly use all available measures to reduce exposure to ionising radiation. Barriers to use of protective mechanisms include lack of availability and perceived impracticality.

The AfricaNZ Health project aimed explore HIV risks in Black African communities in NZ with a view to informing HIV infection prevention and health promotion programs. AfricaNZ Health was completed in two phases. The first developed desk estimates of the resident Black African population in New Zealand, and Africans living with HIV. The second comprised two arms: an anonymous survey administered at African community events and a series of focus groups around the country. High levels of knowledge and positive attitudes about HIV were more often found in older than younger age groups. Condom use was higher in the younger group than in older age groups. Traditional attitudes still inform some beliefs about HIV. Stigma about HIV and anyone at risk for HIV remains very high among Africans. Western sexual identity constructs are not meaningful. A culturally informed strategy for risk and stigma reduction is urgently needed. The existing prevention and care infrastructure, informed by MSM experiences, must address increased risk to Black African new settlers, but this is not a reason to discriminate or further stigmatise an already vulnerable population. © 2014 Public Health Association of Australia.

Competing cues: Older adults rely on knowledge in the face of fluency.

Brashier, Nadia M; Umanath, Sharda; Cabeza, Roberto; Marsh, Elizabeth J

2017-06-01

Consumers regularly encounter repeated false claims in political and marketing campaigns, but very little empirical work addresses their impact among older adults. Repeated statements feel easier to process, and thus more truthful, than new ones (i.e., illusory truth). When judging truth, older adults' accumulated general knowledge may offset this perception of fluency. In two experiments, participants read statements that contradicted information stored in memory; a post-experimental knowledge check confirmed what individual participants knew. Unlike young adults, older adults exhibited illusory truth only when they lacked knowledge about claims. This interaction between knowledge and fluency extends dual-process theories of aging.

AOP: An R Package For Sufficient Causal Analysis in Pathway ...

EPA Pesticide Factsheets

Summary: How can I quickly find the key events in a pathway that I need to monitor to predict that a/an beneficial/adverse event/outcome will occur? This is a key question when using signaling pathways for drug/chemical screening in pharma-cology, toxicology and risk assessment. By identifying these sufficient causal key events, we have fewer events to monitor for a pathway, thereby decreasing assay costs and time, while maximizing the value of the information. I have developed the “aop” package which uses backdoor analysis of causal net-works to identify these minimal sets of key events that are suf-ficient for making causal predictions. Availability and Implementation: The source and binary are available online through the Bioconductor project (http://www.bioconductor.org/) as an R package titled “aop”. The R/Bioconductor package runs within the R statistical envi-ronment. The package has functions that can take pathways (as directed graphs) formatted as a Cytoscape JSON file as input, or pathways can be represented as directed graphs us-ing the R/Bioconductor “graph” package. The “aop” package has functions that can perform backdoor analysis to identify the minimal set of key events for making causal predictions.Contact: burgoon.lyle@epa.gov This paper describes an R/Bioconductor package that was developed to facilitate the identification of key events within an AOP that are the minimal set of sufficient key events that need to be tested/monit

When Sufficiently Processed, Semantically Related Distractor Pictures Hamper Picture Naming.

Prominent speech production models view lexical access as a competitive process. According to these models, a semantically related distractor picture should interfere with target picture naming more strongly than an unrelated one. However, several studies failed to obtain such an effect. Here, we demonstrate that semantic interference is obtained, when the distractor picture is sufficiently processed. Participants named one of two pictures presented in close temporal succession, with color cueing the target. Experiment 1 induced the prediction that the target appears first. When this prediction was violated (distractor first), semantic interference was observed. Experiment 2 ruled out that the time available for distractor processing was the driving force. These results show that semantically related distractor pictures interfere with the naming response when they are sufficiently processed. The data thus provide further support for models viewing lexical access as a competitive process.

Evaluation of Flight Attendant Technical Knowledge

NASA Technical Reports Server (NTRS)

Dunbar, Melisa G.; Chute, Rebecca D.; Rosekind, Mark (Technical Monitor)

1997-01-01

Accident and incident reports have indicated that flight attendants have numerous opportunities to provide the flight-deck crew with operational information that may prevent or lessen the severity of a potential problem. Additionally, as carrier fleets transition from three person to two person flight-deck crews, the reliance upon the cabin crew for the transfer of this information may increase further. Recent research indicates that flight attendants do not feel confident in their ability to describe mechanical parts or malfunctions of the aircraft, and the lack of flight attendant technical training has been referenced in a number of recent reports. Chute and Wiener describe five factors which may produce communication barriers between cockpit and cabin crews: the historical background of aviation, the physical separation of the two crews, psychosocial issues, regulatory factors, and organizational factors. By examining these areas of division we can identify possible bridges and address the implications of deficient cockpit/cabin communication on flight safety. Flight attendant operational knowledge may provide some mitigation of these barriers. The present study explored both flight attendant technical knowledge and flight attendant and pilot expectations of flight attendant technical knowledge. To assess the technical knowledge of cabin crewmembers, 177 current flight attendants from two U.S. carriers voluntarily completed a 13-item technical quiz. To investigate expectations of flight attendant technical knowledge, 181 pilots and a second sample of 96 flight attendants, from the same two airlines, completed surveys designed to capture each group's expectations of operational knowledge required of flight attendants. Analyses revealed several discrepancies between the present level of flight attendant operational knowledge and pilots' and flight attendants' expected and desired levels of technical knowledge. Implications for training will be discussed.

Objective. To assess knowledge and awareness of oral cancer in the early identification of risk factors among undergraduate dental students. Methods. A total of 162 undergraduate (third, fourth, and fifth year) dental students at International Islamic University, Malaysia, were approached to participate in the study, and those who agreed were administered. A 9-item pretested questionnaire contains questions on oral examination, oral cancer risk factors, and requests for further information. Descriptive statistics were conducted using chi-square testing. Results. The response rate of the study was 70.3% (114/162), with 26 (22.8%) males and 88 (77.2%) females. All undergraduate dental students were familiar with examining the oral mucosa of their patients and most were likely to advise patients about the risk factors for developing oral cancer (98.2%). Nearly one-third (32.4%) of students reported examining patients with oral lesions as early signs for oral cancer (P < 0.001) and nearly 70% agreed that they did not have sufficient knowledge regarding the prevention and detection of oral cancer (P < 0.001). In addition, more than 95.6% agreed that there is a need for additional information/teaching regarding oral cancer. Further, 61.3% and 14.1% identified tobacco smoking and drinking alcohol as major risk factors for developing oral cancer. Conclusion. This study demonstrated lack of awareness about risk factors among undergraduate dental students regarding oral cancer. Reinforcing awareness and enhancing the benefits of early detection on prevention of oral cancer should be done through training and/or educational intervention. PMID:26839548

Teacher knowledge, instructional expertise, and the development of reading proficiency.

Reid Lyon, G; Weiser, Beverly

2009-01-01

Teacher knowledge and instructional expertise have been found in correlational and pre- and posttest studies to be related to student reading achievement. This article summarizes data presented in this special issue and additional research to address four questions: (a) What do expert reading teachers know? (b) Why do teachers need to acquire this knowledge? (c) Do teachers believe they have this knowledge? and (d) Are teachers being adequately prepared to teach reading? Well-designed studies relevant to this topic have been sparse with a noticeable lack of attention given to identifying specific causal links between teacher knowledge, teaching expertise, and student reading achievement. Until the appropriate research designs and methodologies are applied to address the question of causal effects, conclusions about the specific content that teachers must know and the instructional practices that are most beneficial in presenting this content are preliminary at best. Future studies of the effect of essential reading content knowledge must be extended beyond word-level skills to vocabulary, reading comprehension, and writing.

Ebola virus proteins NP, VP35, and VP24 are essential and sufficient to mediate nucleocapsid transport.

2018-01-30

The intracytoplasmic movement of nucleocapsids is a crucial step in the life cycle of enveloped viruses. Determination of the viral components necessary for viral nucleocapsid transport competency is complicated by the dynamic and complex nature of nucleocapsid assembly and the lack of appropriate model systems. Here, we established a live-cell imaging system based on the ectopic expression of fluorescent Ebola virus (EBOV) fusion proteins, allowing the visualization and analysis of the movement of EBOV nucleocapsid-like structures with different protein compositions. Only three of the five EBOV nucleocapsid proteins-nucleoprotein, VP35, and VP24-were necessary and sufficient to form transport-competent nucleocapsid-like structures. The transport of these structures was found to be dependent on actin polymerization and to have dynamics that were undistinguishable from those of nucleocapsids in EBOV-infected cells. The intracytoplasmic movement of nucleocapsid-like structures was completely independent of the viral matrix protein VP40 and the viral surface glycoprotein GP. However, VP40 greatly enhanced the efficiency of nucleocapsid recruitment into filopodia, the sites of EBOV budding.

2017-04-13

The aim of this study was to examine perceived barriers to assessment of delirium for critical care nurses, and the impact of education on their knowledge and practice. Delirium is a significant problem in critical care, leading to increased morbidity and mortality. Many authors have found variations in assessment by critical care nurses, but there has been limited analysis of the reasons for this. Education on the topic improves knowledge and practice, but the best approach has not been examined. A questionnaire survey design. A self-reported questionnaire was distributed to critical care nurses (n=31) at a district general hospital. Data were analysed with descriptive statistics. Knowledge and practice were variable, but correlation was seen between nursing band and years of experience with better scores. Any type of education led to significantly improved scores. Several barriers to assessment were found, with the most common being lack of knowledge and difficulty in assessing intubated patients. It is essential to improve practice in delirium assessment and management. Education is vital to improve the knowledge and practice of critical care nurses regarding delirium.

Little is known about women’s knowledge of breast density or between-race differences in this knowledge. In the current study, we examined knowledge of breast density and awareness of its role as a breast cancer risk factor among women who had previously taken part in a breast imaging study. Seventy-seven women (54.5 % Black) returned a survey assessing perceptions and accuracy of breast density knowledge, knowledge of one’s own breast density, and breast cancer risk awareness. White women had greater perceived knowledge of breast density compared to Black women; however, differences in the accuracy of definitions of breast density were due to education. Black women were less likely to know how dense their own breasts were. Black and White women both lacked awareness that having dense breast increased breast cancer risk. The results highlight the need to disseminate information regarding breast density to women, while ensuring that the information is equally accessible to both Black and White women. PMID:23467999

Raised blood pressure (BP) remains an important risk factor for cardiovascular diseases such as stroke. Adherence to therapeutic recommendations especially antihypertensive drugs is important in BP control. The aim of the study was to assess the stroke risk factors and levels of adherence among hypertensive patients with stroke in Kampala Uganda. In a cross-sectional study we describe 112 hypertensive subjects with stroke from two Kampala city hospitals. A standardized pre-tested questionnaire was used to collect medical history, clinical details, radiological findings and laboratory data. A total of 112 hypertensive subjects with stroke were enrolled between May 2013 and April 2014. The median ages were 63.5 years (52.5-75.0) for the cases. Seventy percent (78/112) of the study participants had ischemic strokes. Only 17% were adherent to anti-hypertensive medications. The main cause of non-adherence appears to be lack of knowledge. Poor adherence of anti-hypertensive medications among hypertensive patients remains a big challenge in our setting. This has been attributed to lack of adequate knowledge and cost of the prescribed drugs. There is therefore an urgent need to promptly diagnose and educate hypertensive patients with emphasis on adherence to anti hypertensive drugs.

This study aims to develop learners’ thinking structures through associations, case based, and schematic method so that different knowledge structures have a role in influencing the structure of creative thinking. The learners have low mastery of physics materials since they are not given sufficient opportunity to build their own knowledge. They should be directed to approach each new problem or task with their prior knowledge, assimilate new information, and construct their own understanding. The design of this research was a quasi-experiment using purposive sampling. Data were analyzed using variance analysis. The design of this research was a quasi-experiment using purposive sampling. Data were analyzed using variance analysis. The learning process of problemsolving consists of: 1) identifying problems, 2) planning projects, 3) creating projects, 4) presenting projects, and 5) evaluating projects. From the results of this research, it can be concluded that problem-solving method can provide strong supports in developing the learners’ creative thinking skills as they can share their knowledge and interact with their friends and the environment. This learning activity also constitutes an appropriate technique to help the learners to develop problem solving knowledge and skills.

An Educational Intervention to Evaluate Nurses' Knowledge of Heart Failure.

Nurses are the main providers of patient education in inpatient and outpatient settings. Unfortunately, nurses may lack knowledge of chronic medical conditions, such as heart failure. The purpose of this one-group pretest-posttest intervention was to determine the effectiveness of teaching intervention on nurses' knowledge of heart failure self-care principles in an ambulatory care setting. The sample consisted of 40 staff nurses in ambulatory care. Nurse participants received a focused education intervention based on knowledge deficits revealed in the pretest and were then resurveyed within 30 days. Nurses were evaluated using the valid and reliable 20-item Nurses Knowledge of Heart Failure Education Principles Survey tool. The results of this project demonstrated that an education intervention on heart failure self-care principles improved nurses' knowledge of heart failure in an ambulatory care setting, which was statistically significant (p < .05). Results suggest that a teaching intervention could improve knowledge of heart failure, which could lead to better patient education and could reduce patient readmission for heart failure.

Is self-sufficiency financially viable and ethically justifiable?--a commercial viewpoint.

PubMed

Christie, R B

1994-12-01

Manufacturers of blood products have to maintain the highest possible standards for plasma screening and good manufacturing practices to ensure maximum purity and viral safety. The private sector companies have much experience in implementing and complying with national and international regulations. These requirements involve considerable cost in the areas of (1) plasma collection facilities, (2) research and clinical research, (3) manufacture, and (4) quality control. Total self-sufficiency would mean the loss of many existing resources. An alternative would be a collaboration between the public and private sectors to meet the needs of all patients who require plasma derived products. The current definition of self-sufficiency suggests that it is not financially viable.

In resource-limited countries, health policy makers and practitioners need to know whether healthcare workers have sufficient knowledge of tuberculosis and its management. We conducted a study to: (1) measure knowledge changes among healthcare workers who participated in a tuberculosis training programme; and (2) make recommendations about future tuberculosis training for healthcare workers in the KwaZulu-Natal Department of Health. A cross-sectional study conducted in 2007 measured changes in tuberculosis knowledge of doctors, nurses and other healthcare workers after a training programme based on World Health Organization tuberculosis training modules. Data were collected before and after training using a self-administered, 98-item questionnaire covering eight components. A total of 267 healthcare workers, mean age 40.7 years, answered both pre- and post-training questionnaires. Mean total knowledge scores were low despite significant changes (p<0.001) from a pre-training score of 59.5% to a post-training score of 66.5%. Nurses showed significant improvements in mean total knowledge scores (p<0.001) but had the lowest mean total knowledge score post-training, 63.2%. Doctors had significantly better pre-training (p<0.001) and post-training (p<0.001) mean total knowledge scores compared to nurses. Improvement in healthcare workers' overall knowledge of tuberculosis during a training programme was not clinically significant. Periodic field training and supervision should be considered to ensure tuberculosis knowledge improvements.

How does the knowledge environment shape procurement practices for orthopaedic medical devices in Mexico?

Lingg, Myriam; Wyss, Kaspar; Durán-Arenas, Luis

2016-07-08

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

One third of women reported GWG knowledge consistent with guidelines. Women overweight prior to pregnancy were less likely to underestimate appropriate GWG (RRR 0.23, 95% CI=0.09-0.59). Conversely, women in the overweight (RRR 8.80, 95% CI=4.02-19.25) and obese (RRR 19.62, 95% CI=8.03-48.00) categories were more likely to overestimate GWG recommendations, while tertiary educated women were less likely to overestimate GWG (RRR 0.28, 95% CI=0.10-0.79). No associations were found between GWG knowledge and pregnancy, GWG information source or attitudinal variables. the findings highlight women's lack of GWG knowledge and the role of pre-pregnancy body mass index and women's education as correlates of GWG knowledge. Women susceptible to poor GWG knowledge should be a priority target for individual and community-based education. Copyright © 2016 Elsevier Ltd. All rights reserved.

Improving nurses' knowledge of continuous ST-segment monitoring.

Chronister, Connie

2014-01-01

Continuous ST-segment monitoring can result in detection of myocardial ischemia, but in clinical practice, continuous ST-segment monitoring is conducted incorrectly and underused by many registered nurses (RNs). Many RNs are unable to correctly institute ST-segment monitoring guidelines because of a lack of education. To evaluate whether an educational intervention, provided to 32 RNs, increases knowledge and correct clinical decision making (CDM) for the use of continuous ST-segment monitoring. At a single institution, an ST-segment monitoring class was provided to RNs in 2 cardiovascular units. Knowledge and correct CDM instruments were used for a baseline pretest and subsequent posttest after ST-segment monitoring education. Statistical significance between pretest and posttest scores for knowledge and correct CDM practice was noted with dependent t tests (P = .0001). Many RNs responsible for electrocardiographic monitoring are not aware of evidence-based ST-segment monitoring practice guidelines and cannot properly place precordial leads needed for ST-segment monitoring. Knowledge and correct CDM with ST-segment monitoring can be improved with focused education.

Despite the efforts of national and international organizations, polio has not been eradicated from Pakistan. The prevalence of polio in Pakistan is exceptional in global context. Quetta and Peshawar divisions are amongst the most affected regions hit by polio in Pakistan. This study was carried out to assess the knowledge, attitudes and perceptions towards polio immunization among residents of Quetta and Peshawar divisions in Pakistan. A descriptive, cross-sectional study involving 768 participants was conducted from August to December, 2014 in Quetta and Peshawar divisions in Pakistan. Multistage sampling technique was used to draw a sample of residents from each division. A pre-tested, self-administered questionnaire was used to collect the data from eligible participants. Descriptive and logistic regression analyses were used to express the results. A total of 38.8 % participants exhibited good knowledge about polio. Mean knowledge score of the participants was 7.35 ± 2.54 (based on 15 knowledge questions). Older age (p < 0.001), low qualification (p < 0.05), rural locality (p < 0.05) and Quetta division (p < 0.001) were significantly associated with poor knowledge of polio. A large proportion of participants displayed negative attitudes towards polio immunization (84.8 %), with a mean score of 19.19 ± 2.39 (based on 8 attitude statements). Lack of education (p < 0.001) and rural residence (p < 0.001) were significantly associated with the negative attitudes of participants towards polio immunization. False religious beliefs (39.06 %), lack of knowledge (33.7 %), fear of infertility by polio vaccines (32.16 %) and security issues (29.42 %) were reported by the participants as the main barriers towards polio immunization. The findings of this study showed poor knowledge and negative attitudes of participants towards polio immunizations. Religious beliefs and lack of knowledge about polio immunization were reported as the major

Studies on health behaviors have observed several barriers to breast cancer screening, including lack of breast cancer knowledge, distrust of health care providers, and long waiting times to be screened or to receive screening results. We conducted a nested case-control study among a subsample of 200 women 21 years of age and older [100 patients (cases)], who had been diagnosed with breast cancer, and 100 controls, who were screened and found to be free of breast cancer), all residing in the Toluca metropolitan area in central Mexico. We examined how knowledge of breast cancer screening guidelines, perceptions of screening methods, and quality of health care influenced the use of breast cancer screening among study participants. Our study found that the most important factor associated with the decision to have breast cancer screenings was having a positive perception of the quality of care provided by the local health care centers, such as having competent clinic personnel, sufficient screening equipment, and reasonable waiting times to receive screening and to receive the screening results. Therefore, individual health care centers need to focus on the patients' perception of the services received by optimizing the care provided and, in so doing, increase the rates of early diagnosis and reduce the rate of mortality from breast cancer as well as its associated treatment costs.

Studies on health behaviors have observed several barriers to breast cancer screening, including lack of breast cancer knowledge, distrust of health care providers, long waiting times to be screened or to receive screening results. We conducted a nested case-control study among a subsample of 200 women 21 years of age and older (100 cases, who had been diagnosed with breast cancer, and 100 controls, who were screened and found to be free of breast cancer), all residing in the Toluca metropolitan area in central Mexico. We examined how knowledge of breast cancer screening guidelines, perceptions of screening methods, and quality of health care influenced the use of breast cancer screening among study participants. Our study found that the most important factors associated with the decision to have breast cancer screenings was having a positive perception of the quality of care provided by the local health care centers, such as having competent clinic personnel, sufficient screening equipment, and reasonable waiting times to receive screening and to receive the screening results. Therefore, individual health care centers need to focus on the patients’ perception of the services received by optimizing the care provided, and in so doing increase the rates of early diagnosis, reduce the rate of mortality from breast cancer as well as its associated treatment costs.

To assess nurses' knowledge about pressure ulcers in an Iranian orthopaedic ward. A cross-sectional, self-report questionnaire study using Pieper's Pressure Ulcer Knowledge Test (PUKT). Orthopaedic nurses' knowledge about pressure ulcers was examined in two teaching hospitals in Iran. The questionnaire consisted of 41 true or false assertions, categorised according to pressure ulcer classification and onset, wound characteristics and preventive measure. Of 68 nurses, 57 participated in this study (response rate of 84%); of the respondents, 68%(n=39) were women and 32% (n= 18) were men. Mean age of participants was 30.2 ± 5.1 years and mean years of experience was 6.9 ± 4.6 years. The overall rate of correct responses by nurses was 70.1%.Nurses had the highest level of knowledge in the pressure ulcer prevention category and the lowest in the pressure ulcer categorisation and onset section. No relationship was found between level of knowledge and nurses' years of experience. Pressure ulcer prevention is one of the most important roles of nurses in an orthopaedic setting. The results of this study suggest that orthopaedic nurses in Iran were not sufficiently knowledgeable about pressure ulcers. Therefore, there is a need to improve their knowledge with some targeted, educational programmes.

Podgórski, Daniel

2010-01-01

A systematic approach to occupational safety and health (OSH) management and concepts of knowledge management (KM) have developed independently since the 1990s. Most KM models assume a division of knowledge into explicit and tacit. The role of tacit knowledge is stressed as necessary for higher performance in an enterprise. This article reviews literature on KM applications in OSH. Next, 10 sections of an OSH management system (OSH MS) are identified, in which creating and transferring tacit knowledge contributes significantly to prevention of occupational injuries and diseases. The roles of tacit knowledge in OSH MS are contrasted with those of explicit knowledge, but a lack of a model that would describe this process holistically is pointed out. Finally, examples of methods and tools supporting the use of KM in OSH MS are presented and topics of future research aimed at enhancing KM applications in OSH MS are proposed.

Barriers to healthcare for transgender individuals.

2016-04-01

Transgender persons suffer significant health disparities and may require medical intervention as part of their care. The purpose of this manuscript is to briefly review the literature characterizing barriers to healthcare for transgender individuals and to propose research priorities to understand mechanisms of those barriers and interventions to overcome them. Current research emphasizes sexual minorities' self-report of barriers, rather than using direct methods. The biggest barrier to healthcare reported by transgender individuals is lack of access because of lack of providers who are sufficiently knowledgeable on the topic. Other barriers include: financial barriers, discrimination, lack of cultural competence by providers, health systems barriers, and socioeconomic barriers. National research priorities should include rigorous determination of the capacity of the US healthcare system to provide adequate care for transgender individuals. Studies should determine knowledge and biases of the medical workforce across the spectrum of medical training with regard to transgender medical care; adequacy of sufficient providers for the care required, larger social structural barriers, and status of a framework to pay for appropriate care. As well, studies should propose and validate potential solutions to address identified gaps.

2003-01-01

To assess the knowledge and attitudes of owners/managers of commercial skin-penetration premises regarding infection control. A telephone survey was conducted with a randomly selected sample of 874 owners/managers. Participants appeared to lack knowledge of essential infection-control practices. Less than 39% correctly identified recommended disinfection procedures, and between 12% to 67% were not aware of inappropriate sterlization procedures. Almost all participants accepted the need for guidelines. Half acknowledged a need to improve their infection-control compliance, and most accepted having their premises regularly checked by the councils. There is a considerable opportunity to increase infection-control compliance among skin-penetration operators.

Lack of global health knowledge places immigrants at risk of iatrogenic morbidity. Although global health education programs have grown in popularity, measurable impact is lacking. We previously surveyed 363 physicians in training across 15 programs in four countries in 2004 regarding basic parasite knowledge and recognition of Strongyloides risk through a theoretical case scenario. In 2005, the University of Minnesota implemented a formal global health training program (GHP). In 2009, the identical survey was repeated. Strongyloidiasis recognition increased from 11.1% (19/171) in 2004 to 39.4% (50/127) in 2009 (P < 0.001). Trainees participating in formal didactic and interactive curriculum had superior recognition (77% versus 29%; P < 0.001). In a multivariate model of GHP training activities, participation in an American Society of Tropical Medicine and Hygiene-accredited global health certificate course increased recognition (odds ratio = 9.5, 95% confidence interval = 2.5–36, P = 0.001), whereas participation in international electives alone did not (P = 0.9). A formal GHP curriculum was associated with improved knowledge regarding common parasitic infections and the risk of iatrogenic morbidity and mortality due to strongyloidiasis. PMID:21896795

Studies have indicated that US physicians may not consider Chagas disease when diagnosing immigrant patients from Chagas-endemic areas. The purpose of this study was to evaluate physician knowledge of Chagas disease in six Appalachian Ohio counties. Physician knowledge was assessed by self-administrated survey (n = 105). Over 80 % of physicians reported that their current knowledge of Chagas disease was limited or very limited, and 50 % reported never considering Chagas disease diagnosis for their at-risk patients. Nearly 70 % of physicians were unaware of the percentage of chronic Chagas patients that develop clinical disease, and 36 % could not correctly identify the disease course. In addition, over 30 % of physicians reported that no services were available within their practice to assist Spanish-speaking patients with limited English proficiency. A lack of physician awareness of Chagas disease, coupled with a lack of translation services, may create a barrier to care by decreasing the likelihood of identification of patients at risk for Chagas disease. The results of this study support the need for interventions to ensure proper diagnosis and treatment of Chagas disease in Hispanic immigrants in rural Appalachian Ohio.

Purpose: In order to achieve a higher vaccination rate, education on HPV as well as options for prophylaxis performed by doctors is of great importance. One opportunity to increase the protection against HPV would be vaccinating boys. This study evaluated attitude and knowledge among German gynecologists regarding HPV vaccination, especially in boys. Material and Methods: A questionnaire with 42 questions about demographics, attitude and knowledge about HPV and HPV vaccination was sent to members of the German Society for Gynecology and Obstetrics (DGGG). Results: 998 out of 6567 addressed gynecologists participated. Knowledge about HPV, associated diseases and possible HPV vaccines was high among participants. The attitude towards vaccination in boys as well as girls was positive. Only 8.2 % refused to vaccinate their sons whereas 2.2 % refused to do this for their daughters. However, only few gynecologists vaccinated their daughters and sons against HPV. Main reason for girls was an age outside of vaccination guidelines; for boys it was the lack of cost coverage. Conclusion: The willingness of gynecologists to perform HPV vaccination in boys is as high as for girls. However, sons of gynecologists are only rarely vaccinated against HPV. Main reason is the lack of cost coverage. Vaccinating boys could decrease the disease burden in males, as well as protect women by interrupting ways of transmission. Since the main argument against vaccination of boys is only of financial nature, the necessity of a vaccination recommendation for boys needs to be re-evaluated taking into account the cost-reduced 2-dose vaccination scheme.

Ward nurses' knowledge of computed tomography scanning.

PubMed

Majeed, M A; Nayeemuddin, M; Christie, M

Patients benefit from and are reassured by advance information on procedures that they are to undergo. Ward nurses should have adequate knowledge of radiological investigations to ensure proper patient preparation and good interdepartmental communication to avoid delays and cancellations. This study was conducted to assess the ward nurses' knowledge of the process of computed tomography (CT) scanning. One hundred and twenty qualified nurses were asked to complete a questionnaire regarding CT scanning. The findings revealed a suboptimal level of awareness about the process. This is probably due to lack of formal teaching for nurses on the wards in regards the different radiological procedures and patient preparation. There is a strong case for better educational talks on rapidly changing radiological techniques for ward staff to ensure high-quality patient care.

Patients with chronic kidney disease (CKD) do not always receive care consistent with guidelines, in part due to complexities in CKD management, lack of randomized trial data to inform care, and a failure to disseminate best practice. At a 2007 conference of key Canadian stakeholders in kidney disease, attendees noted that the impact of Canadian Society of Nephrology (CSN) guidelines was attenuated given limited formal linkages between the CSN Clinical Practice Guidelines Group, kidney researchers, decision makers and knowledge users, and that further knowledge was required to guide care in patients with kidney disease. The idea for the Canadian Kidney Knowledge Translation and Generation Network (CANN-NET) developed from this meeting. CANN-NET is a pan-Canadian network established in partnership with CSN, the Kidney Foundation of Canada and other professional societies to improve the care and outcomes of patients with and at risk for kidney disease. The initial priority areas for knowledge translation include improving optimal timing of dialysis initiation, and increasing the appropriate use of home dialysis. Given the urgent need for new knowledge, CANN-NET has also brought together a national group of experienced Canadian researchers to address knowledge gaps by encouraging and supporting multicentre randomized trials in priority areas, including management of cardiovascular disease in patients with kidney failure.

This study explores the level of sexual knowledge among chilean university students in 4 different professions, compares their responses and verifies them with selected socio-demographic variables. 813 university students were interviewed in 1st and 3rd year medical school, law and engineering from the University of Chile and in education, from the Superior Blas Canas Institute of Pedagogy. The group is equally divided between each of the 4 professions; 64.7% are men with 95.5% single and 84.7% are between 17.22; only 37.5% attended a mixed school; 73.1% are Catholic. The survey aimed to evaluate knowledge, attitude and practices (KAP) but this article only analyzes the attitudes of students through 6 variables: anatomy and physiology, pregnancy and delivery, contraception, venereal diseases, sources claimed by the interviewee to receive information and self-evaluation of actual levels of knowledge. Results demonstrated knowledge about anatomy and physiology, pregnancy and delivery and venereal diseases, but great disparity with contraception. Students are not learning about methods of contraception in school, possibly due to fear on the part of the faculty or their own lack of information. 3 factors influenced levels of knowledge: 1) formal education; 2) experience; and 3) personal interest. The highest results were from students of medicine with the lowest being students in engineering and education. Those that were in their 3rd year of school or married appeared more knowledgeable possibly due to more sexual experience and the need to prevent pregnancies. The females in all variables scored higher due to their own interest in preventing pregnancies, and because women are socialized in interpersonal relations and maternity issues. More than 1/2 the students gave themselves bad evaluations concerning their levels of sexual knowledge.

Funding bodies, policy makers, researchers and clinicians are seeking strategies to increase the translation of knowledge between research and practice. Participatory research encompasses a range of approaches for clinicians' involvement in research in the hope of increasing the relevance and usability of research. Our aim was to explore how knowledge is translated and integrated in participants' presentations and negotiations about knowledge. Twelve collaboration meetings were observed, and discussions between researchers and clinicians were recorded. The material was examined using the following analytical terms: knowledge object, knowledge form, knowledge position and knowledge tasks. We identified a recurring rhetorical pattern in translational processes that we call 'relevance testing': a strategy by which the participants attempt to create coherence and identify relevance across different contexts. The limitation of this translational strategy was a tendency to reinforce a 'two-communities' logic: re-establishing the separated worlds and rationales between clinicians and researchers. The 'translational work' that unfolds during discussions remains implicit. It may be that participants are unable to explicitly address and identify the knowledge translation processes because they lack necessary conceptual tools. Our results contribute to increased awareness about translational processes and provide a language through which barriers to translation can be addressed. © The Author(s) 2016.

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

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.

How common is "common knowledge" about child witnesses among legal professionals? Comparing interviewers, public defenders, and forensic psychologists with laypeople.

The present study evaluates the knowledge of jury-eligible college students (n = 192), investigative interviewers (n = 44), forensic psychologists (n = 39), and public defenders (n = 137) in regard to the research on interviewing children. These groups' knowledge was compared with the scientific research on the impact of interview techniques and practices on the accuracy of child witnesses. Jury-eligible students were the least knowledgeable, but their accuracy varied widely across items. Both interviewers and public defenders performed better than jury-eligible students, but they lacked substantial knowledge about the research on interviewing children on certain topics (e.g., using anatomically detailed dolls); forensic psychologists were the most knowledgeable. These findings suggest that professionals in the legal system need substantial professional development regarding the research on interviewing strategies with child witnesses. They also highlight the need for experts to provide case-relevant information to juries who lack basic information about the validity and reliability of children's reports.

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.

To evaluate Utah community pharmacists' knowledge and attitudes toward recommendation of human papillomavirus (HPV) vaccine, to determine whether the knowledge and attitude of pharmacists regarding the HPV vaccine influence their recommendation behaviors, and to capture any self-identified barriers to recommending the HPV vaccine. A cross-sectional anonymous 73-item survey was developed and administered to community, outpatient, and ambulatory care pharmacists. Utah. Utah community pharmacists. Recommendation of the HPV vaccine by the pharmacist, knowledge and attitude of pharmacists regarding HPV vaccine, and barriers to vaccine receipt. The mean HPV vaccine knowledge score was 7.45 ± 2.15 (out of 13), and scores were higher when pharmacists had 4 to 6 technicians per day in the pharmacy and when they were residency trained. The mean attitude score was 24.26 ± 3.16 (out of 30). Positive attitudes were found if they had more than 1 pharmacist and 4 to 6 pharmacy technicians working at any given time in the pharmacy. Those who identified with "other Christianity" had a more positive attitude than Latter Day Saints. Although positive attitude toward the HPV vaccine was a predictor for recommending the vaccine to both boys and girls, higher knowledge was a significant predictor only in recommending the HPV vaccine for boys. Female pharmacists were more likely to recommend the HPV vaccine. The top 3 reported barriers included lack of parental knowledge, parental concerns and opposition, and lack of educational materials to provide parents. Although the majority of respondents perceived HPV vaccination as useful for preventing certain types of cancer, and more than one-half of respondents reported being comfortable in recommending the vaccine, only one-third actually recommended the vaccine for girls and for boys. The results indicate the need for improving knowledge about the HPV vaccine for pharmacists, patients, and parents. Copyright © 2018 American Pharmacists

Drama is used to build knowledge and understanding in science as part of a socio-linguistic, constructivist approach. Role-plays, where learners act as analogues for components and processes, help access abstract ideas. However, a problem restricting many science teachers using these approaches has been that they lack sufficient pedagogical…

Knowledge-based vision and simple visual machines.

PubMed Central

Cliff, D; Noble, J

1997-01-01

The vast majority of work in machine vision emphasizes the representation of perceived objects and events: it is these internal representations that incorporate the 'knowledge' in knowledge-based vision or form the 'models' in model-based vision. In this paper, we discuss simple machine vision systems developed by artificial evolution rather than traditional engineering design techniques, and note that the task of identifying internal representations within such systems is made difficult by the lack of an operational definition of representation at the causal mechanistic level. Consequently, we question the nature and indeed the existence of representations posited to be used within natural vision systems (i.e. animals). We conclude that representations argued for on a priori grounds by external observers of a particular vision system may well be illusory, and are at best place-holders for yet-to-be-identified causal mechanistic interactions. That is, applying the knowledge-based vision approach in the understanding of evolved systems (machines or animals) may well lead to theories and models that are internally consistent, computationally plausible, and entirely wrong.

2017-04-01

Analysis of food security level of household is a novelty of measurement standards which usually includes regional and national levels. With household approach is expected to provide the basis of sharp food policy formulation. The purpose of this study are to identify the condition of self-sufficiency in staple foods, and to find the main factors affecting the dynamics of self-sufficiency in staple foods on farm household level in Great Solo. Using primary data from 50 farmers in the sample and secondary data in Great Solo (Surakarta city, Boyolali, Sukoharjo, Karanganyar, Wonogiri, Sragen and Klaten). Compiled panel data were analyzed with linear probability regression models to produce a good model. The results showed that farm households in Great Solo has a surplus of staple food (rice) with an average consumption rate of 96.8 kg/capita/year. This number is lower than the national rate of 136.7 kg/capita/year. The main factors affecting the level of food self-sufficiency in the farmer household level are: rice production, rice consumption, land tenure, and number of family members. Key recommendations from this study are; improvement scale of the land cultivation for rice farming and non-rice diversification consumption.

A 'Knowledge Ecologies' Analysis of Co-designing Water and Sanitation Services in Alaska.

Willingness to collaborate across disciplinary boundaries is necessary but not sufficient for project success. This is a case study of a transdisciplinary project whose success was constrained by contextual factors that ultimately favoured technical and scientific forms of knowledge over the cultural intelligence that might ensure technical solutions were socially feasible. In response to Alaskan Water and Sewer Challenge (AWSC), an international team with expertise in engineering, consultative design and public health formed in 2013 to collaborate on a two-year project to design remote area water and sanitation systems in consultation with two native Alaskan communities. Team members were later interviewed about their experiences. Project processes are discussed using a 'Knowledge Ecology' framework, which applies principles of ecosystems analysis to knowledge ecologies, identifying the knowledge equivalents of 'biotic' and 'abiotic' factors and looking at their various interactions. In a positivist 'knowledge integration' perspective, different knowledges are like Lego blocks that combine with other 'data sets' to create a unified structure. The knowledge ecology framework highlights how interactions between different knowledges and knowledge practitioners ('biotic factors') are shaped by contextual ('abiotic') factors: the conditions of knowledge production, the research policy and funding climate, the distribution of research resources, and differential access to enabling infrastructures (networks, facilities). This case study highlights the importance of efforts to negotiate between different knowledge frameworks, including by strategic use of language and precepts that help translate social research into technical design outcomes that are grounded in social reality.

Nicotine Activation of α4* Receptors: Sufficient for Reward, Tolerance, and Sensitization

The identity of nicotinic receptor subtypes sufficient to elicit both the acute and chronic effects of nicotine dependence is unknown. We engineered mutant mice with α4 nicotinic subunits containing a single point mutation, Leu9' --> Ala9' in the pore-forming M2 domain, rendering α4* receptors hypersensitive to nicotine. Selective activation of α4* nicotinic acetylcholine receptors with low doses of agonist recapitulates nicotine effects thought to be important in dependence, including reinforcement in response to acute nicotine administration, as well as tolerance and sensitization elicited by chronic nicotine administration. These data indicate that activation of α4* receptors is sufficient for nicotine-induced reward, tolerance, and sensitization.

Knowledge-Driven Event Extraction in Russian: Corpus-Based Linguistic Resources

PubMed Central

Solovyev, Valery; Ivanov, Vladimir

2016-01-01

Automatic event extraction form text is an important step in knowledge acquisition and knowledge base population. Manual work in development of extraction system is indispensable either in corpus annotation or in vocabularies and pattern creation for a knowledge-based system. Recent works have been focused on adaptation of existing system (for extraction from English texts) to new domains. Event extraction in other languages was not studied due to the lack of resources and algorithms necessary for natural language processing. In this paper we define a set of linguistic resources that are necessary in development of a knowledge-based event extraction system in Russian: a vocabulary of subordination models, a vocabulary of event triggers, and a vocabulary of Frame Elements that are basic building blocks for semantic patterns. We propose a set of methods for creation of such vocabularies in Russian and other languages using Google Books NGram Corpus. The methods are evaluated in development of event extraction system for Russian. PMID:26955386

Challenges and promises of integrating knowledge engineering and qualitative methods

NASA Astrophysics Data System (ADS)

Lundberg, C. Gustav; Holm, Gunilla

Our goal is to expose some of the close ties that exist between knowledge engineering (KE) and qualitative methodology (QM). Many key concepts of qualitative research, for example meaning, commonsense, understanding, and everyday life, overlap with central research concerns in artificial intelligence. These shared interests constitute a largely unexplored avenue for interdisciplinary cooperation. We compare and take some steps toward integrating two historically diverse methodologies by exploring the commonalities of KE and QM both from a substantive and a methodological/technical perspective. In the second part of this essay, we address knowledge acquisition problems and procedures. Knowledge acquisition within KE has been based primarily on cognitive psychology/science foundations, whereas knowledge acquisition within QM has a broader foundation in phenomenology, symbolic interactionism, and ethnomethodology. Our discussion and examples are interdisciplinary in nature. We do not suggest that there is a clash between the KE and QM frameworks, but rather that the lack of communication potentially may limit each framework's future development.

Gendered knowledge and adaptive practices: Differentiation and change in Mwanga District, Tanzania.

PubMed

Smucker, Thomas A; Wangui, Elizabeth Edna

2016-12-01

We examine the wider social knowledge domain that complements technical and environmental knowledge in enabling adaptive practices through two case studies in Tanzania. We are concerned with knowledge production that is shaped by gendered exclusion from the main thrusts of planned adaptation, in the practice of irrigation in a dryland village and the adoption of fast-maturing seed varieties in a highland village. The findings draw on data from a household survey, community workshops, and key informant interviews. The largest challenge to effective adaptation is a lack of access to the social networks and institutions that allocate resources needed for adaptation. Results demonstrate the social differentiation of local knowledge, and how it is entwined with adaptive practices that emerge in relation to gendered mechanisms of access. We conclude that community-based adaptation can learn from engaging the broader social knowledge base in evaluating priorities for coping with greater climate variability.

More than Anecdotes: Fishers' Ecological Knowledge Can Fill Gaps for Ecosystem Modeling.

PubMed

Bevilacqua, Ana Helena V; Carvalho, Adriana R; Angelini, Ronaldo; Christensen, Villy

2016-01-01

Ecosystem modeling applied to fisheries remains hampered by a lack of local information. Fishers' knowledge could fill this gap, improving participation in and the management of fisheries. The same fishing area was modeled using two approaches: based on fishers' knowledge and based on scientific information. For the former, the data was collected by interviews through the Delphi methodology, and for the latter, the data was gathered from the literature. Agreement between the attributes generated by the fishers' knowledge model and scientific model is discussed and explored, aiming to improve data availability, the ecosystem model, and fisheries management. The ecosystem attributes produced from the fishers' knowledge model were consistent with the ecosystem attributes produced by the scientific model, and elaborated using only the scientific data from literature. This study provides evidence that fishers' knowledge may suitably complement scientific data, and may improve the modeling tools for the research and management of fisheries.

2015-01-01

This paper reports findings from a systematic review of the literature on the general public's knowledge and understanding of dementia/Alzheimer's disease. The key purpose of the review was to evaluate existing literature with specific attention paid to conceptual and methodological issues and to key findings. Over a 20-year period, 40 published articles satisfied the inclusion criteria. Only 4 of these were qualitative and 5 were cross-national. The review revealed a lack of consistency across studies regarding how knowledge was operationalized, approaches to sampling, response rates, and data collection instruments used including validated scales. A consistent finding across the vast majority of studies was the only fair to moderate knowledge and understanding the general public had. The most common misconception was that dementia was a normal part of aging and there was a lack of clarity about at which point normal age-related memory loss problems become severe enough to indicate dementia. Knowledge of dementia was found to be particularly poor among racial and ethnic minority groups where several myths about causes of dementia were found. Findings point to the need for more educational and advocacy programmes on dementia to be developed particularly in low-income to middle-income countries.

Improving adolescent knowledge of emergency contraception: challenges and solutions

Seetharaman, Sujatha; Yen, Sophia; Ammerman, Seth D

2016-01-01

Globally, unintended adolescent pregnancies pose a significant burden. One of the most important tools that can help prevent unintended pregnancy is the timely use of emergency contraception (EC), which in turn will decrease the need for abortions and complications related to adolescent pregnancies. Indications for the use of EC include unprotected sexual intercourse, contraceptive failure, or sexual assault. Use of EC is recommended within 120 hours, though is most effective if used as soon as possible after unprotected sex. To use EC, adolescents need to be equipped with knowledge about the various EC methods, and how and where EC can be accessed. Great variability in the knowledge and use of EC around the world exists, which is a major barrier to its use. The aims of this paper were to 1) provide a brief overview of EC, 2) discuss key social determinants affecting knowledge and use of EC, and 3) explore best practices for overcoming the barriers of lack of knowledge, use, and access of EC.

2007-01-01

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.

The aim of this study was to assess the socio-demographic and disease-related symptoms and emotions and knowledge expectations of patients recently diagnosed with knee osteoarthritis. A further aim was to determine associations between selected demographic variables and patients' expected knowledge. Patient counselling and information provision are recommended for all patients with knee osteoarthritis. In healthcare centres, there is a good possibility to establish the knowledge expectations of patients with knee osteoarthritis during counselling. Recent empirical evidence indicates a lack of research on knowledge expectations among recently diagnosed patients with knee osteoarthritis. A quantitative, descriptive inquiry design was adopted. The data were collected from 252 recently diagnosed patients with knee osteoarthritis by a postal survey in 2013, using the Hospital Patient's Knowledge Expectations Scale as well as additional questions and statements. The data were analysed using multivariate linear regression. Most of the respondents were female pensioners who also had other chronic diseases. Approximately half of the participants had had counselling on osteoarthritis. Knowledge expectations concerning pain management were emphasized. From the empowering knowledge perspective, the highest knowledge expectations concerned bio-physiological dimensions of knowledge, followed by ethical and financial dimensions. Age, employment status, pain and emotions of concern and hope among women and tiredness or fatigue and vocational/higher education among men were associated with knowledge expectations. Patients with knee osteoarthritis have high knowledge expectations and there is a need to improve the counselling and care of pain and tiredness or fatigue symptoms. The development of the counselling of recently diagnosed patients with knee osteoarthritis also needs further research. © 2016 John Wiley & Sons Ltd.

Knowledge-based zonal grid generation for computational fluid dynamics

NASA Technical Reports Server (NTRS)

Andrews, Alison E.

1988-01-01

Automation of flow field zoning in two dimensions is an important step towards reducing the difficulty of three-dimensional grid generation in computational fluid dynamics. Using a knowledge-based approach makes sense, but problems arise which are caused by aspects of zoning involving perception, lack of expert consensus, and design processes. These obstacles are overcome by means of a simple shape and configuration language, a tunable zoning archetype, and a method of assembling plans from selected, predefined subplans. A demonstration system for knowledge-based two-dimensional flow field zoning has been successfully implemented and tested on representative aerodynamic configurations. The results show that this approach can produce flow field zonings that are acceptable to experts with differing evaluation criteria.

Preservice and inservice teachers' knowledge of language constructs in Finland.

Aro, Mikko; Björn, Piia Maria

2016-04-01

The aim of the study was to explore the Finnish preservice and inservice teachers' knowledge of language constructs relevant for literacy acquisition. A total of 150 preservice teachers and 74 inservice teachers participated in the study by filling out a questionnaire that assessed self-perceived expertise in reading instruction, knowledge of phonology and phonics, and knowledge of morphology. The inservice teachers outperformed the preservice teachers in knowledge of phonology and phonics, as well as morphology. Both groups' knowledge of morphology was markedly lower than their knowledge of phonology and phonics. Because early reading instruction does not focus on the morphological level of language but is phonics-based, this result was expected. However, the findings also revealed a lack of explicit knowledge of basic phonological constructs and less-than-optimal phonemic awareness skills in both groups. Problems in phonemic skills manifested mostly as responding to the phonological tasks based on orthographic knowledge, which reflects an overreliance on the one-to-one correspondence between graphemes and phonemes. The preservice teachers' perceptions of expertise were weakly related to their knowledge and skills. Among the inservice teachers, perceived expertise and knowledge of language constructs were completely unrelated. Although the study was exploratory, these findings suggest that within the Finnish teacher education there is a need to focus more on explicit content studies for language structures and the concepts relevant for literacy instruction, as well as phonological and phonemic skills.

A misfolded protein conformation is not a sufficient condition for in vivo glucosylation by the UDP-Glc:glycoprotein glucosyltransferase.

PubMed

Fernández, F; D'Alessio, C; Fanchiotti, S; Parodi, A J

1998-10-15

A key element in the quality control of glycoprotein folding is the UDP-Glc:glycoprotein glucosyltransferase (GT), which in cell-free assays exclusively glucosylates misfolded glycoproteins. In order to test if such a protein conformation is a sufficient condition for in vivo glucosylation of all N-linked oligosaccharides by GT, a Schizosaccharomyces pombe double mutant (gls2/alg6) was constructed. With this mutant, Man9GlcNAc2 is transferred to proteins and no removal of glucose units added by GT occurs as it lacks glucosidase II. The same proportion of glucosylated (Glc1Man9GlcNAc2) and unglucosylated (Man9GlcNAc2 and Man8GlcNAc2) endoplasmic reticulum (ER)-specific compounds was produced when cells were pre-incubated for 10, 20 or 30 min and further incubated with [14C]glucose for 10 min at 28 degrees C with or without 5 mM dithiothreitol (DTT), thus indicating not only that DTT did not affect protein glucosylation but also that no increased glucosylation of glycoproteins occurred in the presence of the drug. Monitoring Golgi-specific modifications of oligosaccharides after pulse-chase experiments performed in the presence or absence of 5 mM DTT showed that exit of the bulk of glycoproteins synthesized from the ER and thence their proper folding had been prevented by the drug. Cells pulse-chase labeled at 37 degrees C in the absence of DTT also yielded glucosylated and unglucosylated protein-linked oligosaccharides without Golgi-specific modifications. It was concluded that a misfolded protein conformation is not a sufficient condition for in vivo glucosylation of all N-linked oligosaccharides by GT.

2012-12-01

Induced abortion is more frequent in Sweden than in many other Western countries. We wanted to investigate attitudes and knowledge about induced abortion among politicians responsible for healthcare in three Swedish counties. A study-specific questionnaire was sent to all 375 elected politicians in three counties; 192 (51%) responded. The politicians stated that they were knowledgeable about the Swedish abortion law. More than half did not consider themselves, in their capacity as politicians, sufficiently informed about abortion-related matters. Most politicians (72%) considered induced abortion to be primarily a 'women's rights issue' rather than an ethical one, and 54% considered 12 weeks' gestational age an adequate upper limit for induced abortion. Only about a third of the respondents were correctly informed about the number of induced abortions annually carried out in Sweden. Information and knowledge on induced abortion among Swedish county politicians seem not to be optimal. Changes aimed at reducing the current high abortion rates will probably not be easy to achieve as politicians seem to be reluctant to commit themselves on ethical issues and consider induced abortion mainly a women's rights issue.

2011-02-01

Metabolic diseases and cardiovascular disease (CVD), the incidence of which is currently increasing in Korea, can be managed well with dietary education and modification. However, it has yet to be established whether nurses have sufficient knowledge to impart appropriate nutritional counseling to patients with these diseases. Our study involved 506 nurses working at Asan Medical Center, Samsung Medical Center, and Seoul National University Hospital between March and May, 2006. The questionnaire was comprised of 42 diet-related questions pertaining to diabetes, obesity, and CVD. Nurses' correct-response rate for overall nutritional knowledge was worse than reported in Western countries (58.4%), and particularly so with regard to obesity and CVD. Although many nurses were aware of the therapeutic aspects of nutrients in relation to CVD, most of them had limited knowledge about low-cholesterol diets and sources of water-soluble fiber, fatty acids and the specific food items that prevent CVD. Our results suggest that there is an urgent need to update the contents of nutrition education for nurses to reflect the current changes in the Korean diet and the increasing incidence of metabolic diseases and CVD.

2017-01-01

University students are supposed to be autonomous learners, able to adapt to an educational environment significantly less guided than school. Entering higher education poses a challenge of self-regulation, in which beginning students are often not prepared with self-regulation strategies needed. Since there are many studies assessing self-regulated learning (SRL) via classical self-reports, we know a lot about how students generally self-assess their SRL strategies. However, SRL and performance do not always correlate highly in these studies. The aim of the present study is to determine whether there are discrepancies between students' knowledge about SRL and their action in applying adequate SRL strategies in relevant learning situations. We also want to know whether such discrepancies generalize across domains and what the reasons for discrepancies are. The situation-specific Self-Regulated Learning Questionnaire for Action and Knowledge (SRL-QuAK) was used in a sample of 408 psychology and economic sciences students. Descriptive data analysis was conducted to determine potential discrepancies between SRL knowledge and action and differences between the study domains in an explorative way. The reasons for not using SRL-strategies were derived via qualitative content analysis. The results showed that although students had quite advanced knowledge of SRL strategies, they did not put this knowledge into action. This dissonance between SRL knowledge and action was found in both domains. In terms of reasons, students stated that they (a) lacked the time to use SRL strategies, (b) would not benefit from SRL strategies in the given situation, (c) would not be able to put the strategies to use effectively or (d) found it too arduous to use SRL strategies. The implications of these results will be discussed, e.g., the consequences for measures to overcome students' dissonance between knowledge and action and therefore to promote academic performance and well-being.

Formal knowledge networks are considered among the solutions for strengthening knowledge translation and one of the elements of innovative systems in developing and developed countries. In the year 2000, knowledge networks were established in Iran's health system to organize, lead, empower, and coordinate efforts made by health-related research centers in the country. Since the assessment of a knowledge network is one of the main requirements for its success, the current study was designed in two qualitative and quantitative sections to identify the strengths and weaknesses of the established knowledge networks and to assess their efficiency. In the qualitative section, semi-structured, in-depth interviews were held with network directors and secretaries. The interviews were analyzed through the framework approach. To analyze effectiveness, social network analysis approach was used. That is, by considering the networks' research council members as 'nodes', and the numbers of their joint articles--before and after the network establishments--as 'relations or ties', indices of density, clique, and centrality were calculated for each network. In the qualitative section, non-transparency of management, lack of goals, administrative problems were among the most prevalent issues observed. Currently, the most important challenges are the policies related to them and their management. In the quantitative section, we observed that density and clique indices had risen for some networks; however, the centrality index for the same networks was not as high. Consequently the attribution of density and clique indices to these networks was not possible. Therefore, consolidating and revising policies relevant to the networks and preparing a guide for establishing managing networks could prove helpful. To develop knowledge and technology in a country, networks need to solve the problems they face in management and governance. That is, the first step towards the realization of true

Antimicrobial knowledge and confidence amongst final year medical students in Australia.

PubMed

Weier, Naomi; Thursky, Karin; Zaidi, Syed Tabish R

2017-01-01

Inappropriate use of antimicrobials is one of the major modifiable contributors to antimicrobial resistance. There is currently no validated survey tool available to assess knowledge and confidence of medical students in infectious diseases (ID) compared to other diseases states, and little is known about this topic. A cross-sectional survey of final year medical students attending universities around Australia was conducted between August and September, 2015. A survey unique from other published studies was developed to survey satisfaction in education, confidence and knowledge in ID, and how this compared to these factors in cardiovascular diseases. Reliability and validity was demonstrated in the survey tool used. Students were more likely to rate university education as sufficient for cardiovascular diseases (91.3%) compared to ID (72.5%), and were more confident in their knowledge of cardiovascular diseases compared to ID (74.38% vs. 53.76%). Students tended to answer more cardiovascular disease related clinical questions correctly (mean score 78%), compared to questions on antimicrobial use (mean score 45%). Poor knowledge and confidence amongst final year medical students in Australia were observed in ID. Antimicrobial stewardship agenda should include the provision of additional training in antimicrobial prescribing to the future medical workforce.

Cervical cancer is the most frequent cancer of women in the Democratic Republic of Congo (DRC). Nevertheless, the level of women's awareness about cervical cancer is unknown. Knowledge, attitude and practice (KAP) are important elements for designing and monitoring screening programs. The study purpose was to estimate KAP on cervical cancer and to identify associated factors. A cross-sectional study was conducted in Kinshasa, DRC, including 524 women aged 16-78 years (median age 28; interquartile range 22-35). The women were interviewed at home by trained field workers using a standardized questionnaire. The women's score on knowledge, attitude and practice were dichotomized as sufficient or insufficient. We used binary and multiple logistic regression to assess associations between obtaining sufficient scores and a series of socio-demographic factors: age, residence, marital status, education, occupation, religion, and parity. The women's score on knowledge was not significantly correlated with their score on practice (Spearman's rho = 0.08; P > 0.05). Obtaining a sufficient score on knowledge was positively associated with higher education (adjusted odds ratio (OR) 7.65; 95% confidence interval (95% CI) 3.31-17.66) and formal employment (adjusted OR 3.35; 95% CI 1.85-6.09); it was negatively associated with being single (adjusted OR 0.44; 95% CI 0.24-0.81) and living in the eastern, western and northern zone of Kinshasa compared to the city centre. The attitude score was associated with place of residence (adjusted OR for east Kinshasa: 0.49; 95% CI 0.27-0.86 and for south Kinshasa: 0.48; 95% CI 0.27-0.85) and with religion (adjusted OR 0.55; 95% CI 0.35-0.86 for women with a religion other than Catholicism or Protestantism compared to Catholics). Regarding practice, there were negative associations between a sufficient score on practice and being single (adjusted OR 0.24; 95% CI 0.13-0.41) and living in the eastern zone of the city (adjusted OR 0.39; 95

Older Indian diabetics lack proper health literacy making them vulnerable to complications. Assessment of health literacy was done by hospital-based cross-sectional study. Face-to-face interview was conducted by pretested structured questionnaires. Diabetes patients aged ≥60 years consisted of 56.22% males and 43.78% females; in addition, 34.2% respondents were without formal schooling. Diabetes was known to 63.56% respondents. Total knowledge and practice score of the respondents was good (18.9% and 35.1%), average (30.7% and 46.9%), and poor (50.4% and 18%), respectively. Knowledge and practice score was strongly associated (P< .01) with religion, educational status, and diabetes duration with positive relationship (R 2 = 0.247,P< .01) between knowledge and practice score. The study highlights lack of health literacy among older diabetics undergoing ayurveda management. Baseline statistics will pave the way toward ayurpharmacoepidemiology. © The Author(s) 2016.

Tobacco smoking is common among various social groups. There is still high prevalence of smoking among health care professionals. The aim of the study was to assess knowledge about smoke-free law in public places in Poland among smoking and nonsmoking students of selected medical university. We surveyed 50 students of one medical university aged 23 +/- 2 years. Control group consisted with 61 students of other universities located in the same region aged 23 +/- 3 years. We developed a new survey to assess students knowledge about smoke-free regulations and their implementations in various public places. Smoking status was verified with exhaled carbon monoxide levels (COex). 57% off all surveyed students declared being familiar with smoke-free law. However, we detected a significant difference between the knowledge of medical vs. nonmedical students (76% vs. 41%, p < 0.05). The knowledge about smoke-free law in Poland among students is not sufficient, especially among nonmedical students.

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.

Aldehyde dehydrogenase-2 (ALDH2) catalyzes vascular bioactivation of the antianginal drug nitroglycerin (GTN), resulting in activation of soluble guanylate cyclase (sGC) and cGMP-mediated vasodilation. We have previously shown that a minor reaction of ALDH2-catalyzed GTN bioconversion, accounting for about 5% of the main clearance-based turnover yielding inorganic nitrite, results in direct NO formation and concluded that this minor pathway could provide the link between vascular GTN metabolism and activation of sGC. However, lack of detectable NO at therapeutically relevant GTN concentrations (≤1 μm) in vascular tissue called into question the biological significance of NO formation by purified ALDH2. We addressed this issue and used a novel, highly sensitive genetically encoded fluorescent NO probe (geNOp) to visualize intracellular NO formation at low GTN concentrations (≤1 μm) in cultured vascular smooth muscle cells (VSMC) expressing an ALDH2 mutant that reduces GTN to NO but lacks clearance-based GTN denitration activity. NO formation was compared with GTN-induced activation of sGC. The addition of 1 μm GTN to VSMC expressing either wild-type or C301S/C303S ALDH2 resulted in pronounced intracellular NO elevation, with maximal concentrations of 7 and 17 nm, respectively. Formation of GTN-derived NO correlated well with activation of purified sGC in VSMC lysates and cGMP accumulation in intact porcine aortic endothelial cells infected with wild-type or mutant ALDH2. Formation of NO and cGMP accumulation were inhibited by ALDH inhibitors chloral hydrate and daidzin. The present study demonstrates that ALDH2-catalyzed NO formation is necessary and sufficient for GTN bioactivation in VSMC. © 2016 by The American Society for Biochemistry and Molecular Biology, Inc.
