Educational standardization and gender differences in mathematics achievement: A comparative study.

PubMed

We argue that between-country variations in the gender gap in mathematics are related to the level of educational system standardization. In countries with standardized educational systems both genders are exposed to similar knowledge and are motivated to invest in studying mathematics, which leads to similar achievements. We hypothesize that national examinations and between-teacher uniformity in covering major mathematics topics are associated with a smaller gender gap in a country. Based on Trends of International Mathematical and Science Study (TIMSS) 2003, we use multilevel regression models to compare the link of these two factors to the gender gap in 32 countries, controlling for various country characteristics. The use of national examinations and less between-teacher instructional variation prove major factors in reducing the advantage of boys over girls in mathematics scores and in the odds of excelling. Factors representing gender stratification, often analyzed in comparative gender-gap research in mathematics, are at most marginal in respect of the gap. Copyright © 2012 Elsevier Inc.

Gaps in college biology students' understanding of photosynthesis: Implications for human constructivist learning theory and college classroom practice

NASA Astrophysics Data System (ADS)

Griffard, Phyllis Baudoin

1999-11-01

The main research question of this study was: What gaps in biochemical understanding are revealed by a range of university introductory biology students as they work through a critically acclaimed multimedia program on photosynthesis, and what are the corresponding implications for elaboration of the Ausubel-Novak-Gowin Learning Theory (ANG, now Human Constructivism)? Twelve students, mixed for ability, gender and ethnicity, were recruited from two sections of "Bio 101." Before and after instruction in photosynthesis, in-depth clinical interviews were conducted during which participants completed a range of cognitive tasks such as sorting, concept mapping, explaining and predicting. Some tasks involved interacting with a computer simulation of photosynthesis. This study primarily employed qualitative case study and verbal analysis methods. Verbal analysis of the clinical interviews revealed numerous gaps that were categorized into typologies. The two major categories were propositional gaps and processing gaps. Propositional gaps were evident in development of participants' concepts, links and constructs. Significant among these were conceptual distance gaps and continuity of matter gaps. Gaps such as convention gaps and relative significance gaps seem to be due to naivete in the discipline. Processing gaps included gaps in graphic decoding skills and relevant cognitive habits such as self-monitoring and consulting prior knowledge. Although the gaps were easier to detect and isolate with the above-average participants, all participants showed evidence of at least some of these gaps. Since some gaps are not unexpected at all but the highest literacy levels, not all the gaps identified are to be considered deficiencies. The gaps identified support the attention given by ANG theorists to the role of prior knowledge and metacognition as well as the value of graphic organizers in knowledge construction. In addition, this study revealed numerous gaps in graphic decoding, indicating that both direct experience and explicit instruction are needed if students are to "learn how to learn with graphics," especially those graphics central to understanding a computer simulation's representations of structures, inputs, processes and outputs. It is hypothesized that gaps similar to those revealed in this study may be at the root of some alternative conceptions documented in the literature.

The Knowledge Gap Versus the Belief Gap and Abstinence-Only Sex Education.

PubMed

Hindman, Douglas Blanks; Yan, Changmin

The knowledge gap hypothesis predicts widening disparities in knowledge of heavily publicized public affairs issues among socioeconomic status groups. The belief gap hypothesis extends the knowledge gap hypothesis to account for knowledge and beliefs about politically contested issues based on empirically verifiable information. This analysis of 3 national surveys shows belief gaps developed between liberals and conservatives regarding abstinence-only sex education; socioeconomic status-based knowledge gaps did not widen. The findings partially support both belief gap and knowledge gap hypotheses. In addition, the unique contributions of exposure to Fox News, CNN, and MSNBC in this process were investigated. Only exposure to Fox News was linked to beliefs about abstinence-only sex education directly and indirectly through the cultivation of conservative ideology.

Bridging the gaps: An overview of wood across time and space in diverse rivers

NASA Astrophysics Data System (ADS)

Wohl, Ellen

2017-02-01

Nearly 50 years of research focused on large wood (LW) in rivers provide a basis for understanding how wood enters rivers; how wood decays, breaks, and is transported downstream; and how at least temporarily stable wood influences channel geometry, fluxes of water, sediment, and organic matter, and the abundance and diversity of aquatic and riparian organisms. Field-based studies have led to qualitative conceptual models and to numerical stimulations of river processes involving wood. Numerous important gaps remain, however, in our understanding of wood dynamics. The majority of research on wood in rivers focuses on small- to medium-sized rivers, defined using the ratio of wood piece size to channel width as channels narrower than the locally typical wood-piece length (small) and slightly narrower than the longer wood pieces present (medium). Although diverse geographic regions and biomes are represented by one or a few studies in each region, the majority of research comes from perennial rivers draining temperate conifer forests. Regional syntheses most commonly focus on the Pacific Northwest region of North America where most of these studies originate. Consequently, significant gaps in our understanding include lack of knowledge of wood-related processes in large rivers, dryland rivers, and rivers of the high and low latitudes. Using a wood budget as an organizing framework, this paper identifies other gaps related to wood recruitment, transport, storage, and how beavers influence LW dynamics. With respect to wood recruitment, we lack information on the relative importance of mass tree mortality and transport of buried or surficial downed wood from the floodplain into the channel in diverse settings. Knowledge gaps related to wood transport include transport distances of LW and thresholds for LW mobility in small to medium rivers. With respect to wood storage, we have limited data on longitudinal trends in LW loads within unaltered large and great rivers and on fluctuations in LW load over time intervals greater than a few years. Other knowledge gaps relate to physical and ecological effects of wood, including the magnitude of flow resistance caused by LW; patterns of wood-related sediment storage for diverse river sizes and channel geometry; quantification of channel-floodplain-LW interactions; and potential threshold effects of LW in relation to physical processes and biotic communities. Finally, knowledge gaps are related to management of large wood and river corridors, including understanding the consequences of enormous historical reductions in LW load in rivers through the forested portions of the temperate zone; and how to effectively reintroduce and manage existing LW in river corridors, which includes enhancing public understanding of the importance of LW. Addressing these knowledge gaps requires more case studies from diverse rivers, as well as more syntheses and metadata analyses.

Graduate medical education has moved towards competency-based training. The aim of this study was to assess hand surgery program directors' opinions of exposure gaps in core competencies rated as essential for hand surgery training. We surveyed the 74 ACGME hand surgery fellowship program directors. Respondents rated their opinion of 9 general areas of practice, 97 knowledge topics, and 172 procedures into one of three categories: essential, exposure needed, or unnecessary. Program directors also rated trainee exposure of each component at their respective program. Moderate and large exposure gaps were respectively defined as presence of at least 25 and 50 % of programs rating trainees as not having proficiency in the component at the end of training. Sixty-two of 74 program directors (84 %) responded to the survey. For the 76 knowledge topics and 98 procedures rated as essential, a majority of the knowledge topics (61 %; n = 46) and procedures (72 %; n = 71) had at least a moderate exposure gap. In addition, 22 % (n = 17) of the essential knowledge topics and 26 % (n = 25) of the essential procedures had a large exposure gap. This study illuminates the discrepancies between what is believed to be important for practicing hand surgeons and graduates' proficiency as perceived by program directors. The field of hand surgery must work to determine if program directors have unrealistic expectations for what is essential for practicing hand surgeons or if reforms are needed to improve exposure to essential skills in hand surgery training.

Tuberculosis, reported as the second most common infectious cause of death worldwide, is a key mortality contributor in developing countries and globally. The disease is endemic in Peru and while relative success was achieved during the 1990s in its control, this slowed as new complications, such as multi drug resistant TB arose. Health centre workers participating in the national DOTS program, create the front-line TB work-force in Peru meaning their knowledge and attitudes about the disease are key in its control. A Spanish language, multiple choice knowledge and attitudes survey was designed based on previous successful studies and the national Peruvian TB control guidelines. It was applied to two health networks in Lima, Peru amongst 301 health workers participating in the national TB control program from 66 different health centres. The study results were analysed to test mean knowledge scores amongst different groups, overall gaps in key areas of TB treatment and control knowledge, and attitudes towards the disease and the national TB control program. A mean knowledge score of 10.1 (+/- 1.7) out of 15 or 67.3% correct was shown. Demographics shown to have an effect on knowledge score were age and level of education. Major knowledge gaps were noted primarily in themes relating to treatment and diagnostics. Greater community involvement including better patient education about TB was seen as important in implementing the national TB control program. Participants were in disagreement about the current distribution of health resources throughout the study area. Discussion Serious knowledge gaps were identified from the survey; these reflect findings from a previous study in Lima and other studies from TB endemic areas throughout the world. Understanding these gaps and observations made by front-line TB workers in Lima may help to improve the national TB control program and other control efforts globally.

We conducted a needs assessment to identify knowledge gaps in the management of tropical diseases by Canadian emergency physicians and identify available, related continuing medical education (CME) resources. A literature review was conducted to summarize challenges in the management of commonly encountered tropical diseases. An anonymous online survey was administered to Canadian emergency physicians using the Canadian Association of Emergency Physicians survey deployment service in July and August 2012. The survey identified self-reported gaps in knowledge and assessed knowledge using case-based vignettes. A list of CME resources was generated from a review of major academic emergency medicine journals, online cases, and conference topics from emergency medicine associations during 2010-2011. Two independent reviewers assessed the relevance of the resources; differences were resolved by consensus. From 635 citations, 47 articles were selected for full review; the majority (66%) were retrospective chart reviews, few (10.6%) had an emergency medicine focus, and fewer still were Canadian (8.5%). In total, 1,128 surveys were distributed, and 296 (27%) participants were included in the study. Most respondents reported "no" (52.4%) or "some" (45.9%) training in tropical medicine. Most (69.9%) rated their comfort in managing patients with tropical diseases as "low." Few (11.1%) respondents reported a tropical disease being misdiagnosed or mismanaged; 44.1% indicated malaria. The perceived need for further training was high (76.7%). Conference workshops were the most highly requested CME modality, followed by case studies and podcasts. Correct answers to case vignettes ranged from 30.7 to 58.4%. Although 2,038 CME titles were extracted from extensive searches, only 6 were deemed relevant. Most Canadian emergency physicians have had minimal training in tropical diseases, reported a low comfort level in their management, and identified a high need for CME opportunities, which are lacking.

The objective of this study was to assess the overall understanding and effectiveness of current inpatient stroke education practice by using the data from the Investigation of Stroke Needs (INVISION) Study, a qualitative study assessing various challenges and barriers of the hemorrhagic stroke survivors and their caregivers. Semi-structured interviews were conducted on patients who were recently hospitalized with intracerebral hemorrhage (ICH) and their caregivers during the follow-up visits. The electronic medical record for each patient was reviewed to assess whether they received standard stroke education material during their hospitalization. A phenomenological approach was utilized to identify gaps of education and knowledge in the targeted sample. A total of 21 participants were interviewed. Despite receiving formal stroke education material during their hospitalization, there were three major gaps in stroke knowledge that participants noted, including (1) lack of stroke knowledge/awareness, (2) need for stroke education, and (3) fear of recurrent stroke and comorbid diseases. The majority of ICH survivors had no memory of their hospitalization. This study suggests a need for increased continuity and communication with health-care providers to address the evolving educational and practical needs of stroke patients and their caregivers after hospital discharge.

2014-07-01

Transferring the knowledge bases between related species may assist in enlarging the yield potential of crop plants. Being cereals, rice and wheat share a high level of gene conservation; however, they differ at metabolic levels as a part of the environmental adaptation resulting in different yield capacities. This review focuses on the current understanding of genetic and molecular regulation of yield-associated traits in both crop species, highlights the similarities and differences and presents the putative knowledge gaps. We focus on the traits associated with phenology, photosynthesis, and assimilate partitioning and lodging resistance; the most important drivers of yield potential. Currently, there are large knowledge gaps in the genetic and molecular control of such major biological processes that can be filled in a translational biology approach in transferring genomics and genetics informations between rice and wheat.

Space systems in the future will probably include high-voltage, high-power energy-storage and -production systems. Two such technologies are high-voltage ac and dc systems and high-power electrodynamic tethers. The working group identified several plasma interaction phenomena that will occur in the operation of these power systems. The working group felt that building an understanding of these critical interaction issues meant that several gaps in our knowledge had to be filled, and that certain aspects of dc power systems have become fairly well understood. Examples of these current collection are in quiescent plasmas and snap over effects. However, high-voltage dc and almost all ac phenomena are, at best, inadequately understood. In addition, there is major uncertainty in the knowledge of coupling between plasmas and large scale current flows in space plasmas. These gaps in the knowledge are addressed.

The unrecognized burden of typhoid fever.

Obaro, Stephen K; Iroh Tam, Pui-Ying; Mintz, Eric Daniel

2017-03-01

Typhoid fever (TF), caused by Salmonella enterica serovar Typhi, is the most common cause of enteric fever, responsible for an estimated 129,000 deaths and more than 11 million cases annually. Although several reviews have provided global and regional TF disease burden estimates, major gaps in our understanding of TF epidemiology remain. Areas covered: We provide an overview of the gaps in current estimates of TF disease burden and offer suggestions for addressing them, so that affected communities can receive the full potential of disease prevention offered by vaccination and water, sanitation, and hygiene interventions. Expert commentary: Current disease burden estimates for TF do not capture cases from certain host populations, nor those with atypical presentations of TF, which may lead to substantial underestimation of TF cases and deaths. These knowledge gaps pose major obstacles to the informed use of current and new generation typhoid vaccines.

To understand individuals' financial behaviors, it is important to understand the financial knowledge gap - the distance between one's objective and subjective financial knowledge. Overestimating one's financial knowledge can lead to risky financial behaviors. To date, limited empirical work has examined how financial knowledge gap varies across age groups. We analyze the size and nature of the financial knowledge gap and its variation across age groups. Using nationally representative data, we find robust evidence that older adults overestimate their financial knowledge. Social workers can assess the financial knowledge gap and educate their clients to protect from financial fraud, exploitation, and abuse.

Addressing the Common Pathway Underlying Hypertension and Diabetes in People Who Are Obese by Maximizing Health: The Ultimate Knowledge Translation Gap

2011-01-01

In accordance with the WHO definition of health, this article examines the alarming discord between the epidemiology of hypertension, type 2 diabetes mellitus (T2DM), and obesity and the low profile of noninvasive (nondrug) compared with invasive (drug) interventions with respect to their prevention, reversal and management. Herein lies the ultimate knowledge translation gap and challenge in 21st century health care. Although lifestyle modification has long appeared in guidelines for medically managing these conditions, this evidence-based strategy is seldom implemented as rigorously as drug prescription. Biomedicine focuses largely on reducing signs and symptoms; the effects of the problem rather than the problem. This article highlights the evidence-based rationale supporting prioritizing the underlying causes and contributing factors for hypertension and T2DM, and, in turn, obesity. We argue that a primary focus on maximizing health could eliminate all three conditions, at best, or, at worst, minimize their severity, complications, and medication needs. To enable such knowledge translation and maximizing health outcome, the health care community needs to practice as an integrated team, and address barriers to effecting maximal health in all patients. Addressing the ultimate knowledge translation gap, by aligning the health care paradigm to 21st century needs, would constitute a major advance. PMID:21423684

Caste- and ethnicity-based inequalities in HIV/AIDS-related knowledge gap: a case of Nepal.

Caste- and ethnicity-based inequalities are major obstacles to achieving health equity. The authors investigated whether there is any association between caste- and ethnicity-based inequalities and HIV-related knowledge within caste and ethnic populations. They used the 2011 Nepal Demographic and Health Survey, a nationally represented cross-sectional study data set. The study sample consisted of 11,273 women between 15 and 49 years of age. Univariate and logistic regression models were used to examine the relationship between caste- and ethnicity-based inequalities and HIV-related knowledge. The study sample was divided into high Hindu caste (47.9 percent), "untouchable" caste (18.4 percent), and indigenous populations (33.7 percent). Within the study sample, the high-caste population was found to have the greatest knowledge of the means by which HIV is prevented and transmitted. After controlling for socioeconomic and demographic characteristics, untouchables were the least knowledgeable. The odds ratio for incomplete knowledge about transmission among indigenous populations was 1.27 times higher than that for high Hindu castes, but there was no significant difference in knowledge of preventive measures. The findings suggest the existence of a prevailing HIV knowledge gap. This in turn suggests that appropriate steps need to be implemented to convey complete knowledge to underprivileged populations.

Kenway, S J; Lant, P A; Priestley, A; Daniels, P

2011-01-01

We have only rudimentary understanding of the complex and pervasive connections between water and energy in cities. As water security now threatens energy and economic security, this is a major omission. Understanding the water-energy nexus is necessary if we want to contribute to solving water and energy issues simultaneously; if we want to stop moving problems from one resource dimension to another. This is particularly relevant in the Australian context where energy use for water supplies is forecast to rapidly escalate, growing around 300% from 2007 levels, by 2030. This paper presents a literature review with an aim of characterising the research to date with a particular focus on cities, the major centres of consumption and growth. It systematically analyses a wide range of papers and summarises the diverse objectives, dimensions, and scale of the research to-date together with knowledge gaps. There are many major gaps. These include energy use associated with water in industrial and commercial operations as well as socio-political perspectives. A major gap is the lack of a unifying theoretical framework and consistent methodology for analysis. This is considered a prerequisite for quantitative trans-city comparisons.

2015-11-01

Soils play a pivotal role in major global biogeochemical cycles (carbon, nutrient, and water), while hosting the largest diversity of organisms on land. Because of this, soils deliver fundamental ecosystem services, and management to change a soil process in support of one ecosystem service can either provide co-benefits to other services or result in trade-offs. In this critical review, we report the state-of-the-art understanding concerning the biogeochemical cycles and biodiversity in soil, and relate these to the provisioning, regulating, supporting, and cultural ecosystem services which they underpin. We then outline key knowledge gaps and research challenges, before providing recommendations for management activities to support the continued delivery of ecosystem services from soils. We conclude that, although soils are complex, there are still knowledge gaps, and fundamental research is still needed to better understand the relationships between different facets of soils and the array of ecosystem services they underpin, enough is known to implement best practices now. There is a tendency among soil scientists to dwell on the complexity and knowledge gaps rather than to focus on what we do know and how this knowledge can be put to use to improve the delivery of ecosystem services. A significant challenge is to find effective ways to share knowledge with soil managers and policy makers so that best management can be implemented. A key element of this knowledge exchange must be to raise awareness of the ecosystems services underpinned by soils and thus the natural capital they provide. We know enough to start moving in the right direction while we conduct research to fill in our knowledge gaps. The lasting legacy of the International Year of Soils in 2015 should be for soil scientists to work together with policy makers and land managers to put soils at the centre of environmental policy making and land management decisions.

Objective To assess the food safety knowledge and practices in meat handling, and to determine microbial load and pathogenic organisms in meat at Mekelle city. Methods A descriptive survey design was used to answer questions concerning the current status of food hygiene and sanitation practiced in the abattoir and butcher shops. Workers from the abattoir and butcher shops were interviewed through a structured questionnaire to assess their food safety knowledge. Bacterial load was assessed by serial dilution method and the major bacterial pathogens were isolated by using standard procedures. Results 15.4% of the abattoir workers had no health certificate and there was no hot water, sterilizer and cooling facility in the abattoir. 11.3% of the butchers didn't use protective clothes. There was a food safety knowledge gap within the abattoir and butcher shop workers. The mean values of bacterial load of abattoir meat, butcher shops and street meat sale was found to be 1.1×105, 5.6×105 and 4.3×106 cfu/g, respectively. The major bacterial pathogens isolated were Escherichia coli, Staphylococcus aureus and Bacillus cereus. Conclusions The study revealed that there is a reasonable gap on food safety knowledge by abattoir and butcher shop workers. The microbial profile was also higher compared to standards set by World Health Organization. Due attention should be given by the government to improve the food safety knowledge and the quality standard of meat sold in the city. PMID:23646306

Predicting the Future Contribution of Himalayan Debris-covered Glaciers to River Discharge: Advances and Challenges

The glaciers and snowfields of the Himalaya are the ultimate source for the many rivers that flow across the Asian subcontinent, but they are diminishing rapidly in the face of sustained climatic change. Predictions of how future river discharge may vary through space and time are hampered by two major knowledge gaps. First, simulations of glacier mass loss in high Asia are severely limited by data availability and assumptions made in the parameterisation of glacier models. Consequently, projections of glacier change vary widely; in Nepal for example, recent estimates of volumetric ice loss by AD2100 have ranged between 8% and 99%. A second major gap in knowledge lies in the coupling between glaciers and downstream areas, and specifically in quantifying the relative contributions of different sources to river flow. Although it is clear that ice and snow melt dominates flow for considerable distances downstream, how this contribution interacts with groundwater supplies with increasing distance from its source remains poorly understood. This presentation will review recent work that closes some of the knowledge gaps in understanding debris-covered glacier behaviour including new results from drilling work on the Khumbu Glacier in Nepal. Additionally, it will report on the outputs from an interdisciplinary study in the Annapurna region of Nepal, which is focussing specifically on disaggregating the relative contributions to flow using isotope-based hydrograph separations. It will finish by exploring the most likely drivers of future changes to water supply, including an evaluation of the impact of glacial lake development, and by identifying the main challenges for future related research.

2013-05-01

The aim of this study was to investigate gaps between knowledge on HIV/AIDS and sexual behavior among teenagers. The study used a cross-sectional design with a representative random sample of 1,158 teenagers (14 to 19 years of age) enrolled in nine public secondary schools and who answered validated questionnaires. Data analysis included descriptive statistics and tests of hypotheses (chi-square, Mann-Whitney and Kruskal-Wallis, Kendall, and Fisher's exact test). The vast majority of the teenagers (98.7%) expressed doubt on at least one question. Condom use during first sexual intercourse was significantly associated with condom use in sexual relations in the previous six months. There was no statistical association between knowledge on HIV/AIDS and frequency of condom use or number of sexual partners. Health actions are needed that link schools to health services, in addition to not only elaborating appropriate information but also valorizing teenagers' individuality in the development of proposals.

Introduction Pakistan accounts for 85.2% of the total polio cases reported worldwide. Healthcare workers (HCWs) are an integral part of immunization campaigns and source of education for the general public. This study aimed to assess the knowledge and attitudes towards polio vaccination among HCWs providing immunisation and education to general public in Quetta and Peshawar divisions of Pakistan. Methods A cross-sectional survey of 490 HCWs was conducted in two major referral public teaching hospitals of Quetta and Peshawar divisions. During February to April, 2015, a random sample of 490 HCWs was invited to participate in this study. Knowledge and attitudes were assessed by using self-administered, anonymous and pretested questionnaire. Descriptive and logistic regression analyses were used to express the results. Results A total of 468 participants responded to the questionnaire, giving a response rate of 95.5%. Overall, participants demonstrated good knowledge and positive attitudes towards polio vaccination. The mean knowledge score of HCWs about polio was 13.42±2.39 (based on 18 knowledge questions) while the mean attitude score was 28.75±5.5 (based on 9 attitudes statements). Knowledge gaps were identified about the incubation period of poliovirus (19.5%), management issues (31.9%), use of polio vaccine in mild illnesses (34.7%) and the consequences of the polio virus (36.9%). The majority of participants agreed that all children should be vaccinated for polio (95.1%), while reservations were noted about the need of a booster (38.9%), and sterility issues associated with polio vaccines (43.6%). Internet (n = 167, 37%) and Posters (n = 158, 35%) were the main sources used by HCWs to educate themselves about polio. Conclusion Participants in this study had good knowledge and positive attitudes towards polio vaccination. Although the data are indicative of gaps in the knowledge of HCWs, the findings may not be generalized to other hospitals in Pakistan. PMID:26559184

The Global Inventor Gap: Distribution and Equality of World-Wide Inventive Effort, 1990–2010

PubMed Central

Toivanen, Hannes; Suominen, Arho

2015-01-01

Applying distance-to-frontier analysis, we have used 2.9 million patents and population data to assess whether the relative capacity of world countries and major regions to create new knowledge and technology has become globally more equal or less equal between 1990 and 2010. We show with the Gini coefficient that the global distribution of inventors has become more equal between major countries and regions. However, this trend has been largely due to the improved performance of only two major countries, China and India. The worst performing regions, totalling a population of almost 2 billion, are actually falling behind. Our results suggest that substantial parts of the global population have fallen further behind countries at the global frontier in their ability to create new knowledge and inventions, and that the catch-up among the least developed and middle-income countries is highly uneven, prompting questions about the nature and future of the global knowledge economy.

2016-03-18

Preterm birth (PTB) is the world's leading cause of death in children under 5 years. In 2013, over one million out of six million child deaths were due to complications of PTB. The rate of decline in child death overall has far outpaced the rate of decline attributable to PTB. Three key reasons for this slow progress in reducing PTB mortality are: (a) the underlying etiology and biological mechanisms remain unknown, presenting a challenge to discovering ways to prevent and treat the condition; (ii) while there are several evidence-based interventions that can reduce the risk of PTB and associated infant mortality, the coverage rates of these interventions in low- and middle-income countries remain very low; and (c) the gap between knowledge and action on PTB--the "know-do gap"--has been a major obstacle to progress in scaling up the use of existing evidence-based child health interventions, including those to prevent and treat PTB.In this review, we focus on the know-do gap in PTB as it applies to policymakers. The evidence-based approaches to narrowing this gap have become known as knowledge transfer and exchange (KTE). In our paper, we propose a research agenda for promoting KTE with policymakers, with an ambitious but realistic goal of reducing the global burden of PTB. We hope that our proposed research agenda stimulates further debate and discussion on research priorities to soon bend the curve of PTB mortality.

2015-01-01

We assessed the state of knowledge regarding the effects of large-scale pollution with neonicotinoid insecticides and fipronil on non-target invertebrate species of terrestrial, freshwater and marine environments. A large section of the assessment is dedicated to the state of knowledge on sublethal effects on honeybees (Apis mellifera) because this important pollinator is the most studied non-target invertebrate species. Lepidoptera (butterflies and moths), Lumbricidae (earthworms), Apoidae sensu lato (bumblebees, solitary bees) and the section "other invertebrates" review available studies on the other terrestrial species. The sections on freshwater and marine species are rather short as little is known so far about the impact of neonicotinoid insecticides and fipronil on the diverse invertebrate fauna of these widely exposed habitats. For terrestrial and aquatic invertebrate species, the known effects of neonicotinoid pesticides and fipronil are described ranging from organismal toxicology and behavioural effects to population-level effects. For earthworms, freshwater and marine species, the relation of findings to regulatory risk assessment is described. Neonicotinoid insecticides exhibit very high toxicity to a wide range of invertebrates, particularly insects, and field-realistic exposure is likely to result in both lethal and a broad range of important sublethal impacts. There is a major knowledge gap regarding impacts on the grand majority of invertebrates, many of which perform essential roles enabling healthy ecosystem functioning. The data on the few non-target species on which field tests have been performed are limited by major flaws in the outdated test protocols. Despite large knowledge gaps and uncertainties, enough knowledge exists to conclude that existing levels of pollution with neonicotinoids and fipronil resulting from presently authorized uses frequently exceed the lowest observed adverse effect concentrations and are thus likely to have large-scale and wide ranging negative biological and ecological impacts on a wide range of non-target invertebrates in terrestrial, aquatic, marine and benthic habitats.

2018-04-01

Cardiomyopathies (CMPs) are an increasingly recognized cause of heart failure and sudden death, particularly in young patients. Since their original description, major advances were achieved in the phenotype knowledge, natural history, and nosography of CMPs leading to different classification systems and therapies. However, a deeper knowledge of different causes, genotype-phenotype link, and natural history in different disease stages (preclinical, overt disease, and end-stage disease) according to a recognized standard of care (ie, international guidelines) is needed. Clinical registries can fill gaps in our knowledge regarding the uncovered issues on cause, clinical course, and management of CMPs. Copyright © 2017 Elsevier Inc. All rights reserved.

This study examines the contribution of the Health Management Bachelor's degree program at an Israeli university to the professional development of its graduates. The aims of this study were: To examine the perceived gaps between acquired knowledge and required knowledge within the workforce; To explore the potential changes in the graduates' occupation conditions or professional status following their studies; To test the contribution of the curricula content studied by the graduates to their understanding, knowledge and integration within the healthcare system; and to examine the graduates perceptions towards required content, that should be added to the curricula. A structured, self-reported questionnaire was administered to 182 Health Management Department individuals whom have graduated from the Bachelors program between the years 2005 and 2009. The majority of the graduates reported the existance of a knowledge gap (greater among males, young and single than among females, older and married graduates). Most of the courses which were ranked as the lowest contributing ones were related to Management (e.g. Mathematics for Social Sciences, Accounting Fundamentals, Finance Theory), while the graduates recommended the inclusion of additional components to the curricula. The study demonstrates that a perceived gap exists between the acquired and the required knowledge of the Health Management Studies graduates. Various changes have been reported by the graduates (such as wage raise and role changes), following their study completion, suggesting that the program has partially contributed to their professional status. A 'Learning by Sharing' forum of academic staff, employers and graduates is recommended.

2017-01-01

Using data from a national survey of South Koreans, this study explores the role of science communication in enhancing three different forms of scientific knowledge ( factual, procedural, and subjective). We first assess learning effects, looking at the extent to which citizens learn science from different channels of communication (interpersonal discussions, traditional newspapers, television, online newspapers, and social media). We then look into the knowledge gap hypothesis, investigating how different communication channels can either widen or narrow the gap in knowledge between social classes. Television was found to function as a "knowledge leveler," narrowing the gap between highly and less educated South Koreans. The role of online newspapers in science learning is pronounced in our research. Reading newspapers online indicated a positive relationship to all three measures of knowledge. Contrary to the knowledge-leveling effect of television viewing, reading online newspapers was found to increase, rather than decrease, the gap in knowledge. Implications of our findings are discussed in detail.

Recreation impacts and management in wilderness: A state-of-knowledge review

Leung, Y.-F.; Marion, J.L.

2000-01-01

This paper reviews the body of literature on recreation resource impacts and their management in the United States, with a primary focus on research within designated wildernesses during the past 15 years since the previous review (Cole 1987b). Recreation impacts have become a salient issue among wilderness scientists, managers and advocates alike. Studies of recreation impacts, referred to as recreation ecology, have expanded and diversified. Research has shifted its focus more towards questions driven by wilderness and park planning frameworks such the Limits of Acceptable Change and the Visitor Experience and Resource Protection. This paper begins by providing an overview of recreation impacts and their significance in wilderness, followed by a review of research approaches and methods. Major findings from recent studies are summarized. The contribution of this knowledge base to management decisionmaking and practices is examined. The paper concludes with a discussion of major knowledge gaps and suggested areas for future research.

Chapman, Kathy; Kelly, Bridget; King, Lesley

2009-06-01

Research in the field of food marketing to children requires a better understanding of the research gaps in order to inform policy development. The purpose of this paper was to propose a framework for classifying food marketing research, using Australian research on food marketing to children to demonstrate how this framework can be used to determine knowledge gaps. A literature review of research databases and 'grey' material was conducted to identify research from the previous 10 years. Studies were classified according to their research focus, and media type, as either: exposure, including content analyses; effects of exposure, including opinions, attitudes and actions resulting from food marketing exposure; regulations, including the type and level of regulation that applies to food marketing; or breaches of regulations, including instances where marketing regulations have been violated. The majority of Australian research on food marketing to children has focused on television advertising and exposure research. Research has consistently shown that the content of food marketing directed at children is predominately for unhealthy foods. There is a lack of research on the effects of food marketing, which would be valuable to inform policy. The development of a logical framework for food marketing research allows for the identification of research gaps and enables research priorities to be identified.

2013-01-01

The majority of research identifying anxiety-promoting parenting behaviors has been conducted with mothers, leaving a gap in current knowledge about the role of fathers’ parenting behaviors. In an attempt to fill this gap, this study compared anxiety-promoting parenting behaviors of anxious mothers and fathers. Parents completed self-report measures of parenting behavior and independent coders rated parenting behaviors (i.e., overcontrol, granting of autonomy, warmth, hostility, anxious behavior) of mothers (n = 34) and fathers (n = 21) during a challenging parent-child interaction task (children were ages 6–12). Results indicated that anxious fathers were observed to be more controlling than anxious mothers; while anxious mothers reported using more punishment and reinforcement of children’s dependence in anxiety provoking situations compared to fathers. Findings extend our knowledge about anxious fathers, and highlight the need for additional research on the impact of fathers’ parenting with respect to the development of child anxiety.

The main aim of the European Study SPOKE (Sanofi-Synthelabo Programme for Outcome Knowledge of Epilepsy) designed by the Department of Neurosciences, Walton Hospital in Liverpool and the Centre for Health Services Research at the University of Newcastle upon Tyne, England, was to describe levels of knowledge about epilepsy among people with epilepsy and their families. It was equally important to identify gaps in understanding the most important aspects of the illness as well as to identify characteristics of people who score poorly on the Epilepsy Knowledge Questionnaire (EKQ). Another aim was to consider the implications of identified gaps in knowledge for future educational and psychosocial interventions. The study was conducted in 10 European countries and included 6156 people with epilepsy and 6506 members of their families. Results presented here relate to data for Poland only, where the examined population consisted of 1028 patients with epilepsy. 1033 questionnaires were returned by carers. Over 40% of all respondents had frequent seizures, and one third were seizure free. Scores on the Epilepsy Knowledge Questionnaire were high for the majority of respondents, but generally lower than in most of the countries. With reference to some aspects of illness important gaps in knowledge have been demonstrated. For example, it was shown that a significant number of respondents provided incorrect answers to questions relating to aspects of the etiology of epilepsy and administration of antiepileptic drug medication. There were a number of significant differences between the profiles of high and low scorers on the EKQ; high scorers were likely to have spent longer on education, have lower scores on the impact of epilepsy scale and report better adjustment to their epilepsy. The results of the study once again underline the importance of continued information among patients with epilepsy and their families in order to achieve.

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

Although the majority of travel-associated communicable diseases can be prevented, the public health burden of these diseases remains significant. Relatively little is known about how travelers know and perceive the health risks associated with travel and how they utilize preventive measures before and while traveling abroad. This study was conducted to determine the level of the knowledge, attitudes, and practices (KAP) of Muscat International Airport travelers about travel health in order to assess the knowledge gap and the need for travel health services in Oman. A cross-sectional study was conducted over a period of 1week using a self-administered questionnaire. The overall level of knowledge about vaccine-preventable diseases, food safety, and preventive measures against insect bites of the participants was inadequate. The practice concerning preventive travel health measures, such as the use of specific immunizations and antimalarial prophylaxis, was very limited, and influenced by some personal and travel-related factors. The inadequate level of travelers' knowledge and poor utilization of travel medicine services highlights the need for the provisions of specialized travel medicine services at the national level and to develop educational materials promoting the importance of pre-travel health advice.

The contraceptive pill is widely used. An accurate knowledge is necessary for correct use. This study sheds light on adolescents' knowledge, attitude and behavior in regard to contraceptive use, in the year 2014. The goal is to provide general practitioners (GP) with information about the potential gaps in knowledge concerning contraceptive use in order to give better counseling and prevent high-risk behavior in adolescents. A quantitative descriptive study was carried out among 14-25-year-old female and male adolescents. Data were collected through a web-based survey using the online survey software Qualtrics (Qualtrics, Provo, UT, USA) and was distributed via the social networking site Facebook. The survey was started by 1185 participants. The most popular contraceptive method among females is the oral contraceptive pill (63.7%). Four out of ten females (42.6%) do not know that when using an emergency pill, they must still take their regular contraceptive pill on the same day. The majority of female respondents (80.0%) go to their general practitioner for a prescription for the pill. Ninety-five percent (95.1%) of the females would feel comfortable asking their GP for extra information about the drug. The sex of the GP does not influence the likelihood of female patients seeking more information. The Internet also seems to serve as an important source of information. We defined a female subgroup, called "vulnerable". The majority of females in the non-vulnerable group (70.4%) protected themselves before their first sexual contact instead of only half of the members in the vulnerable group (51.0%). The level of knowledge among adolescents about contraception is not alarming, but there are a few blind spots. Eliminating these gaps should be the aim of the doctor and pharmacologist.

Imbalances in the knowledge about infant mental health in rich and poor countries: too little progress in bridging the gap.

2014-01-01

The vast majority of infants are born in poor countries, but most of our knowledge about infants and children has emerged from high-income countries. In 2003, M. Tomlinson and L. Swartz conducted a survey of articles on infancy between 1996 and 2001 from major international journals, reporting that a meager 5% of articles emanated from parts of the world other than North America, Europe, or Australasia. In this article, we conducted a similar review of articles on infancy published between 2002 and 2012 to assess whether the status of cross-national research has changed in the subsequent decade. Results indicate that despite slight improvements in research output from the rest of world, only 2.3% of articles published in 11 years included data from low- and middle-income countries--where 90% of the world's infants live. These discrepancies are indicative of the progress still needed to bridge the so-called 10/90 gap (S. Saxena, G. Paraje, P. Sharan, G. Karam, & R. Sadana,) in infant mental health research. Cross-national collaboration is urgently required to ensure expansion of research production in low-resource settings. © 2014 Michigan Association for Infant Mental Health.

Robustness of risk maps and survey networks to knowledge gaps about a new invasive pest.

PubMed

Yemshanov, Denys; Koch, Frank H; Ben-Haim, Yakov; Smith, William D

2010-02-01

In pest risk assessment it is frequently necessary to make management decisions regarding emerging threats under severe uncertainty. Although risk maps provide useful decision support for invasive alien species, they rarely address knowledge gaps associated with the underlying risk model or how they may change the risk estimates. Failure to recognize uncertainty leads to risk-ignorant decisions and miscalculation of expected impacts as well as the costs required to minimize these impacts. Here we use the information gap concept to evaluate the robustness of risk maps to uncertainties in key assumptions about an invading organism. We generate risk maps with a spatial model of invasion that simulates potential entries of an invasive pest via international marine shipments, their spread through a landscape, and establishment on a susceptible host. In particular, we focus on the question of how much uncertainty in risk model assumptions can be tolerated before the risk map loses its value. We outline this approach with an example of a forest pest recently detected in North America, Sirex noctilio Fabricius. The results provide a spatial representation of the robustness of predictions of S. noctilio invasion risk to uncertainty and show major geographic hotspots where the consideration of uncertainty in model parameters may change management decisions about a new invasive pest. We then illustrate how the dependency between the extent of uncertainties and the degree of robustness of a risk map can be used to select a surveillance network design that is most robust to knowledge gaps about the pest.

Human Papillomavirus and Cancer Prevention: Gaps in Knowledge and Prospects for Research, Policy, and Advocacy

2015-01-01

The recognition that human papillomavirus (HPV) infection is the central, necessary cause of cervical cancer paved the way to new fronts of prevention via improved screening methods and HPV vaccination. Much has been learned in all fronts, from the molecular basis of our understanding of how HPV causes disease to the health economics of preventive strategies at the individual and population levels. Progress in other areas of cancer control has yet to show the same multi- and trans-disciplinary gains seen in research on HPV-associated malignancies, which is one of the unequivocal success stories in disease prevention. Yet, as an embarrassment of riches, much more research is needed to fill the gaps in knowledge that remain before we are able to reap the benefits from the knowledge translation from all fronts. Public health research on setting-specific implementation of HPV-based preventive strategies and more concerted advocacy to counter barriers facing the adoption of these strategies are likely to yield major dividends in reducing the burden of HPV-associated diseases.

Understanding the digital divide in the clinical setting: the technology knowledge gap experienced by US safety net patients during teleretinal screening.

PubMed

George, Sheba; Moran, Erin; Fish, Allison; Ogunyemi, Lola

2013-01-01

Differential access to everyday technology and healthcare amongst safety net patients is associated with low technological and health literacies, respectively. These low rates of literacy produce a complex patient "knowledge gap" that influences the effectiveness of telehealth technologies. To understand this "knowledge gap", six focus groups (2 African-American and 4 Latino) were conducted with patients who received teleretinal screenings in U.S. urban safety-net settings. Findings indicate that patients' "knowledge gap" is primarily produced at three points: (1) when patients' preexisting personal barriers to care became exacerbated in the clinical setting; (2) through encounters with technology during screening; and (3) in doctor-patient follow-up. This "knowledge gap" can produce confusion and fear, potentially affecting patients' confidence in quality of care and limiting their disease management ability. In rethinking the digital divide to include the consequences of this knowledge gap faced by patients in the clinical setting, we suggest that patient education focus on both their disease and specific telehealth technologies deployed in care delivery.

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

PubMed Central

2013-01-01

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

The Human Research Program (HRP) is formulated around the program architecture of Evidence-Risk-Gap-Task-Deliverable. Review of accumulated evidence forms the basis for identification of high priority risks to human health and performance in space exploration. Gaps in knowledge or disposition are identified for each risk, and a portfolio of research tasks is developed to fill them. Deliverables from the tasks inform the evidence base with the ultimate goal of defining the level of risk and reducing it to an acceptable level. A comprehensive framework for gap identification, focus, and metrics has been developed based on principles of continuous risk management and clinical care. Research towards knowledge gaps improves understanding of the likelihood, consequence or timeframe of the risk. Disposition gaps include development of standards or requirements for risk acceptance, development of countermeasures or technology to mitigate the risk, and yearly technology assessment related to watching developments related to the risk. Standard concepts from clinical care: prevention, diagnosis, treatment, monitoring, rehabilitation, and surveillance, can be used to focus gaps dealing with risk mitigation. The research plan for the new HRP Risk of Decompression Sickness (DCS) used the framework to identify one disposition gap related to establishment of a DCS standard for acceptable risk, two knowledge gaps related to DCS phenomenon and mission attributes, and three mitigation gaps focused on prediction, prevention, and new technology watch. These gaps were organized in this manner primarily based on target for closure and ease of organizing interim metrics so that gap status could be quantified. Additional considerations for the knowledge gaps were that one was highly design reference mission specific and the other gap was focused on DCS phenomenon.

To systematically examine the evidence for interventions after the return of spontaneous circulation (ROSC) on outcomes from veterinary cardiopulmonary resuscitation and to determine important knowledge gaps. Standardized, systematic evaluation of the literature, categorization of relevant articles according to level of evidence and quality, and development of consensus on conclusions for application of the concepts to clinical post-cardiac arrest care. Academia, referral practice, and general practice. Fifteen standardized clinical questions important for post-cardiac arrest care were asked and research articles relevant to answering these questions were identified through structured, explicit literature database searches. The majority of these articles report research in species other than dogs or cats or consisted of experimental work in canine cardiac arrest models. Outcome metrics reported in these studies widely varied and ranged from quantification of mechanistic endpoints, such as elaboration of reactive oxygen species, to survival, and functional neurologic outcome. Despite the near complete absence of clinical veterinary studies, the process allowed the formulation of statements for several postcardiac arrest treatments that were either supportive, such as mild therapeutic hypothermia or controlled reoxygenation, or neutral, such as for mannitol administration or seizure prophylaxis. Evidence grading allowed transparency in regards to the strength of these recommendations. Moreover, numerous knowledge gaps emerged that will allow generation of a road map for progress in veterinary post-cardiac arrest care. © Veterinary Emergency and Critical Care Society 2012.

Left ventricular diastolic dysfunction in women with nonobstructive ischemic heart disease: insights from magnetic resonance imaging and spectroscopy.

Nelson, Michael D

2017-10-01

Ischemic heart disease, in the absence of obstructive coronary artery disease, is prevalent in women and constitutes a major risk factor for developing major adverse cardiovascular events, including myocardial infarction, stroke, and heart failure. For decades, diagnosis was considered benign and often minimized; however, it is now known that this etiology carries much risk and is a significant burden to the health care system. This review summarizes the current state of knowledge on nonobstructive ischemic heart disease (NOIHD), the association between NOIHD and left ventricular diastolic dysfunction, potential links between NOIHD and the development of heart failure with preserved ejection fraction (HFpEF), and therapeutic options and knowledge gaps for patients living with NOIHD.

Summary Dengue virus (DENV) is a mosquito-borne pathogen that causes up to ~100 million dengue cases each year, placing a major public health, social and economic burden on numerous low- and middle-income countries (LMICs). Major advances by scientists, vaccine developers, and affected communities are revealing new insights and enabling novel interventions and approaches to dengue prevention and control. Such research has highlighted further questions about both the basic understanding of dengue and efforts to develop new tools. We discuss existing approaches to dengue diagnostics, disease prognosis, surveillance, and vector control in LMICs as well as potential consequences of vaccine introduction. We also summarize current knowledge and recent insights into dengue epidemiology, immunology, and pathogenesis, and their implications for understanding natural infection and current and future vaccines.

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

Conventional diagnosis of malaria has relied upon either clinical diagnosis or microscopic examination of peripheral blood smears. These methods, if not carried out exactly, easily result in the over- or under-diagnosis of malaria. The reliability and accuracy of malaria RDTs, even in extremely challenging health care settings, have made them a staple in malaria control programmes. Using the setting of a pilot introduction of malaria RDTs in Greater Garissa, North Eastern Province, Kenya, this study aims to identify and understand perceptions regarding malaria diagnosis, with a particular focus on RDTs, and treatment among community members and health care workers (HCWs). The study was conducted in five districts of Garissa County. Focus group discussions (FGD) were performed with community members that were recruited from health facilities (HFs) supported by the MENTOR Initiative. In-depth interviews (IDIs) and FGDs with HCWs were also carried out. Interview transcripts were then coded and analysed for major themes. Two researchers reviewed all codes, first separately and then together, discussed the specific categories, and finally characterized, described, and agreed upon major important themes. Thirty-four FGDs were carried out with a range of two to eight participants (median of four). Of 157 community members, 103 (65.6%) were women. The majority of participants were illiterate and the highest level of education was secondary school. Some 76% of participants were of Somali ethnicity. Whilst community members and HCWs demonstrated knowledge of aspects of malaria transmission, prevention, diagnosis, and treatment, gaps and misconceptions were identified. Poor adherence to negative RDT results, unfamiliarity and distrust of RDTs, and an inconsistent RDT supply were the main challenges to become apparent in FGDs and IDIs. Gaps in knowledge or incorrect beliefs exist in Greater Garissa and have the potential to act as barriers to complete and correct malaria case management. Addressing these knowledge gaps requires comprehensive education campaigns and a reliable and constant RDT supply. The results of this study highlight education and supply chain as key factors to be addressed in order to make large scale roll out of RDTs as successful and effective as possible.

Evidence-based decision-making 7: Knowledge translation.

PubMed

Manns, Braden J

2015-01-01

There is a significant gap between what is known and what is implemented by key stakeholders in practice (the evidence to practice gap). The primary purpose of knowledge translation is to address this gap, bridging evidence to clinical practice. The knowledge to action cycle is one framework for knowledge translation that integrates policy-makers throughout the research cycle. The knowledge to action cycle begins with the identification of a problem (usually a gap in care provision). After identification of the problem, knowledge creation is undertaken, depicted at the center of the cycle as a funnel. Knowledge inquiry is at the wide end of the funnel, and moving down the funnel, the primary data is synthesized into knowledge products in the form of educational materials, guidelines, decision aids, or clinical pathways. The remaining components of the knowledge to action cycle refer to the action of applying the knowledge that has been created. This includes adapting knowledge to local context, assessing barriers to knowledge use, selecting, tailoring implementing interventions, monitoring knowledge use, evaluating outcomes, and sustaining knowledge use. Each of these steps is connected by bidirectional arrows and ideally involves healthcare decision-makers and key stakeholders at each transition.

A survey was conducted among freshly passed undergraduate doctors of a medical college in Eastern India with the aim to investigate their exposure to oncology patients, their knowledge about various aspects of oncology patient management and their confidence in managing patients with cancer. One hundred and twelve newly passed interns of a Government Medical College in Kolkata were interviewed using semi-structured partly open ended and partly closed end questionnaire. The questionnaire dealt with the qualitative and quantitative aspects of knowledge and perception of the interns about the problem of cancer and its management. A total of 82 interns responded to the questionnaire, with a response rate of 73.2%. About 53% of the respondents have seen less than five patients during their undergraduate ward/clinical postings. Among the respondents, 71% felt they were confident in diagnosing cancer, and about 56% were confident in counseling of patient and their relatives about cancer. About 63% were aware about the role of surgery; however, only 32% and 37.5% were aware about the role of radiotherapy and chemotherapy, respectively. A dismal 12.5% were confident of care of terminal and late stage patients. Preparedness was correlated with exposure to patients with cancer (P = 0.03). Majority (87%) felt the need for incorporating oncology training at the undergraduate level and the most frequent method (67%) suggested for doing so was having separate posting in radiotherapy department/oncology wards. There is glaring knowledge gap among newly passed doctors and integrated oncology postings during undergraduate training and during internship may help seal this gap.

Antiepileptic drugs (AEDs) are mainstay in controlling epileptic seizures. As experts in medications, pharmacists should be able to ensure accuracy of dosing regimens, explain adverse effects, and screen for and alert people with epilepsy (PWE) and their physicians to possible drug-drug interactions (DDIs). The aim of this study was to evaluate pharmacists' knowledge of issues in pharmacotherapy of epilepsy using AEDs. This was a cross-sectional observational study conducted in the Palestinian pharmacy practice. A 10-item case-based questionnaire was used to determine actions taken by pharmacists in theoretical situations in pharmacotherapy of epilepsy. Demographic and practice details of the study participants were also collected. Scores were calculated as percentage of correct answers for each participant. The number of participants was 394. The majority (approximately 75%) identified themselves as community pharmacists. The median score was 33.4% with an IQR of 33.3. Pharmacists who received training on epilepsy and AEDs during their pharmacy degree program were 4.78-fold (95% C.I. of 1.82-12.60) more likely to score ≥50% in the test than those who did not receive training on epilepsy and AEDs. Despite gaps in knowledge, pharmacists tended to perform the necessary action in cases of adverse effects and aggravated seizures associated with AEDs. Pharmacists can play a crucial role in providing essential information on AEDs to patients and prescribers. There are many knowledge gaps that need to be filled. Specifically designed pedagogic and/or training interventions might be helpful in filling these gaps. Copyright © 2016 Elsevier Inc. All rights reserved.

Media use and HIV/AIDS knowledge: a knowledge gap perspective.

Despite the widespread utilization of the mass media in HIV/AIDS prevention, little is known about the knowledge gap that results from disparities in mass media use. This study examined the relationship between HIV/AIDS-related mass media use and HIV/AIDS-related knowledge among urban and rural residents of northwestern Ethiopia. A hierarchical regression analysis indicated that HIV/AIDS-related mass media use has both sequestering and mainstreaming effects in certain segments of the study population, although it was not a significant predictor of HIV/AIDS-related knowledge in the total population. The knowledge gaps between individuals with high and low education and between individuals who experience high and low levels of interpersonal communication about HIV/AIDS narrowed as HIV/AIDS-related media use increased, but the gap between urban and rural residents widened. The widening gap could be explained by differences in perceptions of information salience and several theoretical assumptions. Current mass media information campaigns, which are often prepared and broadcast from urban centers, may not only fail to improve the HIV/AIDS knowledge of the rural populace but also put rural populations at a disadvantage relative to their urban counterparts. Communication interventions informed by socioecological models might be helpful to redress and/or narrow the widening knowledge gap between urban and rural residents. © The Author (2013).

Pakistan's Lady Health Worker Programme aims to provide care to children sick with pneumonia and diarrhoea, which continues to cause 27 % under-five mortality in Pakistan. The quality of supervision received by Lady Health Workers (LHWs) in the programme influence their knowledge and skills, in turn impacting their ability to provide care. This study is part of an implementation research project titled "Nigraan" (an Urdu word meaning supervisor), and explores LHW and Lady Health Supervisor (LHS) perspectives regarding the role of supervision in improving LHWs performance and motivation in district Badin, Sindh, Pakistan. Their knowledge and skills regarding integrated community case management (iCCM) of diarrhoea and pneumonia were also assessed. Fourteen focus group discussions and 20 in-depth interviews were conducted as part of this qualitative inquiry. Analysis was done using QSR NVivo version 10. Most LHWs and LHSs identified pneumonia and diarrhoea as two major causes of death among children under-five. Poverty, illiteracy, poor hygiene and lack of clean drinking water were mentioned as underlying causes of high mortality due to diarrhoea and pneumonia. LHWs and LHSs gaps in knowledge included classification of dehydration, correctly preparing ORS and prescribing correct antibiotics in pneumonia. Lack of training, delayed salaries and insufficient medicines and other supplies were identified as major factors impeding appropriate knowledge and skill development for iCCM of childhood diarrhoea and pneumonia. LHWs considered adequate supervision and the presence of LHSs during household visits as a factor facilitating their performance. LHWs did not have a preference for written or verbal feedback, but LHSs considered written individual feedback to LHWs to be more useful than group and verbal feedback. LHWs have knowledge and skill gaps that prevent them from providing effective care for diarrhoea and pneumonia. Enhanced supportive feedback from LHSs could improve LHWs skills and performance.

Background: Surgical education is continually expanding to encompass new techniques and technologies. It is vital that educational activity is directed at gaps in knowledge and ability to improve the quality of learning. Aim: The aim of this study is to describe a published learning assessment toolkit when applied to participants attending AOTrauma Orthogeriatric Fracture courses. Methods: Precourse, participants received a questionnaire covering 10 competencies to assess knowledge gaps and a 20-question clinical knowledge test. The knowledge gap between perceived and desired knowledge was correlated with clinical knowledge test results to help course faculty focus the course curriculum to meet identified educational needs. A commitment to change survey was also administered. Results: Over 3 courses, 48% of registered attendees responded to the precourse survey, 44.5% responded postcourse. The precourse gap scores were generally highest for 2 competencies (“address secondary prevention,” “build a system of care”) indicating a higher level of motivation to learn in these topics and lowest for a variety of competencies (eg. “restore function early,” “co-manage patient care in the US surgeons group”) indicating lower motivation to learn in these competencies. These precourse gap scores guided adaptations in the course structure. Postcourse gaps were reduced in the 4 cohorts. Large improvements were seen in “Address secondary prevention” and “Build a system of care” in many of the cohorts. Competencies with the lowest precourse knowledge test scores were noted in each cohort. Where low pretest scores were noted, it highlighted the need for faculty to put appropriate emphasis on these topics in the delivery of the course content. Conclusion: The technique of evaluating and identifying gaps in knowledge and ability allows course designers to focus on areas of deficits. Measurable success was shown with a subjectively decreased gap score and objectively improved clinical knowledge, as demonstrated by improved test results after course completion. PMID:23569686

Soils play a pivotal role in major global biogeochemical cycles (carbon, nutrient and water), while hosting the largest diversity of organisms on land. Because of this, soils deliver fundamental ecosystem services, and management to change a soil process in support of one ecosystem service can either provide co-benefits to other services or can result in trade-offs. In this critical review, we report the state-of-the-art understanding concerning the biogeochemical cycles and biodiversity in soil, and relate these to the provisioning, regulating, supporting and cultural ecosystem services which they underpin. We then outline key knowledge gaps and research challenges, before providing recommendations for management activities to support the continued delivery of ecosystem services from soils. We conclude that although there are knowledge gaps that require further research, enough is known to start improving soils globally. The main challenge is in finding ways to share knowledge with soil managers and policy-makers, so that best-practice management can be implemented. A key element of this knowledge sharing must be in raising awareness of the multiple ecosystem services underpinned by soils, and the natural capital they provide. The International Year of Soils in 2015 presents the perfect opportunity to begin a step-change in how we harness scientific knowledge to bring about more sustainable use of soils for a secure global society.

To evaluate the neonatal resuscitation competence of obstetrical trainees to assess the gap in knowledge and to determine training needs. The cross-sectional study was conducted at the Department of Gynaecology and Obstetrics, Civil Hospital, Karachi, from January to March 2013 and comprised House Officers and Postgraduate trainees. A questionnaire was used to test the evaluation skills of different conditions and choice of appropriate action required during neonatal resuscitation. Data was collected and analysed through SPSS 17.0. Of the 102 obstetrical trainees, 44 (43.1%) were House Officers and 58 (56.9%) were Postgraduate trainees with an overall mean age 25.69 +/- 2.3 years. Only 19 (18.6%) subjects cleared the test; 8 (42.1%) of them were House Officers and 11 (57.9%) were Postgraduate trainees. The result did not show any significant difference between those who had previous training or those who had performed neonatal resuscitation and those who had no such exposure. Majority, 92 (90.2%) considered their knowledge inadequate and 99 (97%) favoured that updated neonatal resuscitation programmes should be periodically arranged. The study showed inadequate level of knowledge on neonatal resuscitation amongst obstetrical trainees. There is urgent need of formal training programmes which can make doctors skilful enough to face any adverse neonatal outcome professionally.

Comparing Self-Regulatory and Early Academic Skills as Predictors of Later Math, Reading, and Science Elementary School Achievement

NASA Astrophysics Data System (ADS)

Murrah, William M., III

The achievement score gaps between advantaged and disadvantaged children at school entry is a major problem in education today. Identifying the skills critical for school readiness is an important step in developing interventions aimed at addressing these score gaps. The purpose of this study is to compare a number of school readiness skills with an eye toward finding out which are the best predictors of later academic achievement in math, reading, and science. The predictors were early reading, math, general knowledge, socioemotional skills, and motor skills. Data were obtained from the Early Childhood Longitudinal Study of 1998 (NCES, 1998) database. While controlling for an extensive set of family characteristics, predictions were made across five years - from the end of kindergarten to the end of fifth grade. Consistent with current findings, reading and math skills predicted later achievement. Interestingly, general knowledge, attention, and fine motor skills also proved to be important predictors of later academic achievement, but socioemotional skills were not. The findings were interpreted from a neurobiological perspective involving the development of self-regulation. These school entry skills are used to predict later achievement in reading, math, and science. I argued that in addition to acquiring early academic knowledge, children need to regulate the use of this knowledge to meet academic goals.

Differences among Major Taxa in the Extent of Ecological Knowledge across Four Major Ecosystems

Fisher, Rebecca; Knowlton, Nancy; Brainard, Russell E.; Caley, M. Julian

2011-01-01

Existing knowledge shapes our understanding of ecosystems and is critical for ecosystem-based management of the world's natural resources. Typically this knowledge is biased among taxa, with some taxa far better studied than others, but the extent of this bias is poorly known. In conjunction with the publically available World Registry of Marine Species database (WoRMS) and one of the world's premier electronic scientific literature databases (Web of Science®), a text mining approach is used to examine the distribution of existing ecological knowledge among taxa in coral reef, mangrove, seagrass and kelp bed ecosystems. We found that for each of these ecosystems, most research has been limited to a few groups of organisms. While this bias clearly reflects the perceived importance of some taxa as commercially or ecologically valuable, the relative lack of research of other taxonomic groups highlights the problem that some key taxa and associated ecosystem processes they affect may be poorly understood or completely ignored. The approach outlined here could be applied to any type of ecosystem for analyzing previous research effort and identifying knowledge gaps in order to improve ecosystem-based conservation and management.

Scombrids (tunas, bonitos, Spanish mackerels and mackerels) support important fisheries in tropical, subtropical and temperate waters around the world, being one of the most economically- and socially-important marine species globally. Their sustainable exploitation, management and conservation depend on accurate life history information for the development of quantitative fisheries stock assessments, and in the fishery data-poor situations for the identification of vulnerable species. Here, we assemble life history traits (maximum size, growth, longevity, maturity, fecundity, spawning duration and spawning interval) for the 51 species of scombrids globally. We identify major biological gaps in knowledge and prioritize life history research needs in scombrids based on their biological gaps in knowledge, the importance of their fisheries and their current conservation status according to the International Union for Conservation of Nature Red List. We find that the growth and reproductive biology of tunas and mackerel species have been more extensively studied than for Spanish mackerels and bonitos, although there are notable exceptions in all groups. We also reveal that reproductive biology of species, particular fecundity, is the least studied biological aspect in scombrids. We identify two priority groups, including 32 species of scombrids, and several populations of principal market tunas, for which life history research should be prioritized following the species-specific life history gaps identified in this study in the coming decades. By highlighting the important gaps in biological knowledge and providing a priority setting for life history research in scombrid species this study provides guidance for management and conservation and serves as a guide for biologists and resource managers interested in the biology, ecology, and management of scombrid species.

Bat-borne viruses carry undeniable risks to the health of human beings and animals, and there is growing recognition of the need for a 'One Health' approach to understand their frequently complex spill-over routes. While domesticated animals can play central roles in major spill-over events of zoonotic bat-borne viruses, for example during the pig-amplified Malaysian Nipah virus outbreak of 1998-1999, the extent of their potential to act as bridging or amplifying species for these viruses has not been characterised systematically. This review aims to compile current knowledge on the role of domesticated animals as hosts of two types of bat-borne viruses, henipaviruses and filoviruses. A systematic literature search of these virus-host interactions in domesticated animals identified 72 relevant studies, which were categorised by year, location, design and type of evidence generated. The review then focusses on Africa as a case study, comparing research efforts in domesticated animals and bats with the distributions of documented human cases. Major gaps remain in our knowledge of the potential ability of domesticated animals to contract or spread these zoonoses. Closing these gaps will be necessary to fully evaluate and mitigate spill-over risks of these viruses, especially with global agricultural intensification. Copyright © 2017 Elsevier Ltd.

Expert opinion was assessed to identify current knowledge gaps in determining future changes in Arabian/Persian Gulf (thereafter 'Gulf') coral reefs. Thirty-one participants submitted 71 research questions that were peer-assessed in terms of scientific importance (i.e., filled a knowledge gap and was a research priority) and efficiency in resource use (i.e., was highly feasible and ecologically broad). Ten research questions, in six major research areas, were highly important for both understanding Gulf coral reef ecosystems and also an efficient use of limited research resources. These questions mirrored global evaluations of the importance of understanding and evaluating biodiversity, determining the potential impacts of climate change, the role of anthropogenic impacts in structuring coral reef communities, and economically evaluating coral reef communities. These questions provide guidance for future research on coral reef ecosystems within the Gulf, and enhance the potential for assessment and management of future changes in this globally significant region.

Evidence-based practice (EBP) gaps are widespread across health disciplines. Understanding factors supporting the uptake of evidence can inform the design of strategies to narrow these EBP gaps. Although research utilization (RU) and the factors associated with EBP have been reported in several health disciplines, to date this area has not been reviewed comprehensively in the chiropractic profession. The purpose of this review was to report on the current state of knowledge on EBP, RU, and knowledge translation (KT) in chiropractic. A scoping review using the Arksey and O'Malley framework was used to systematically select and summarize existing literature. Searches were conducted using a combination of keywords and MeSH terms from the earliest date available in each database to May 2015. Quantitative and thematic analyses of the selected literature were conducted. Nearly 85 % (56/67) of the included studies were conducted in Canada, USA, UK or Australia. Thematic analysis for the three categories (EBP, RU, KT) revealed two themes related to EBP (attitudes and beliefs of chiropractors; implementation of EBP), three related to RU (guideline adherence; frequency and sources of information accessed; and perceived value of websites and search engines), and three related to KT (knowledge practice gaps; barriers and facilitators to knowledge use; and selection, tailoring, and implementation of interventions). EBP gaps were noted in the areas of assessment of activity limitation, determination of psychosocial factors influencing pain, general health indicators, establishing a prognosis, and exercise prescription. While most practitioners believed EBP and research to be important and a few studies suggested that traditional and online educational strategies could improve patient care, use of EBP and guideline adherence varied widely. Findings suggest that the majority of chiropractors hold favourable attitudes and beliefs toward EBP. However, much remains to be done for chiropractors to routinely apply evidence into clinical practice. Educational strategies aimed at practicing chiropractors can lead to more EBP and improved patient care. The chiropractic profession requires more robust dissemination and implementation research to improve guideline adherence and patient health outcomes.

Cognitive behavioral therapies (CBTs) are efficacious treatments for anxiety disorders in Latino youth. However, there is a gap in knowledge about moderators of CBT outcomes in Latino youth. This study addresses this gap by examining parental acculturation as a moderator of youth anxiety outcomes in a randomized controlled trial of parent-involved CBT (CBT/P) and peer-involved group CBT (GCBT) in 139 Latino youth (ages 6 to 16 years; mean age = 9.68 years). Comparable youth anxiety reduction effects were found for CBT/P and GCBT. Parental acculturation to majority US culture, but not identification with country of origin, significantly moderated youth anxiety outcomes: at low levels of parental acculturation to majority US culture, youth posttreatment anxiety scores were lower in GCBT than CBT/P; at high levels of parental acculturation to majority US culture, youth posttreatment anxiety scores were lower in CBT/P than GCBT. These findings provide further evidence for the efficacy of CBTs for anxiety disorders in Latino youth and also provide guidance for moving toward personalization of CBTs' selection depending on parental acculturation levels.

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

India plans to eliminate tuberculosis (TB) by 2025, and has identified screening and prevention as key activities. Household contacts (HHCs) of index TB cases are a high-risk population that would benefit from rapid implementation of these strategies. However, best practices for TB prevention and knowledge gaps among HHCs have not been studied. We evaluated TB knowledge and understanding of prevention among tuberculin skin-test (TST) positive HHCs. While extensive information is available in other high-burden settings regarding TB knowledge gaps, identifying how Indian adult contacts view their transmission risk and prevention options may inform novel screening algorithms and education efforts that will be part of the new elimination plan. We approached adult HHC to administer a questionnaire on TB knowledge and understanding of infection. Over 1 year, 100 HHC were enrolled at a tertiary hospital in Pune, India. The study population was 61% (n = 61) female, with a mean age of 36.6 years (range 18-67, SD = 12). Education levels were high, with 78 (78%) having at least a high school education, and 23 (24%) had at least some college education. Four (4%) of our participants were HIV-infected. General TB knowledge among HHC was low, with a majority of participants believing that you can get TB from sharing dishes (70%) or touching something that has been coughed on (52%). Understanding of infection was also low, with 42% believing that being skin-test positive means you have disease. To assess readiness for preventive therapy, we asked participants whether they are at a higher risk of progressing to active disease because of their LTBI status. Fifty-four (55%) felt that they are at higher risk. Only 8% had heard of preventive therapy. Our TB knowledge survey among HHCs with evidence of recent exposure found that knowledge is poor and families are confused about transmission in the household. It is imperative that the Indian program develop tools and incentives that can be used to educate TB cases and their families on what infected HHCs can do to prevent disease, including preventive therapy.

Kelp forests along temperate and polar coastlines represent some of most diverse and productive habitats on the Earth. Here, we synthesize information from >60 years of research on the structure and functioning of kelp forest habitats in European waters, with particular emphasis on the coasts of UK and Ireland, which represents an important biogeographic transition zone that is subjected to multiple threats and stressors. We collated existing data on kelp distribution and abundance and reanalyzed these data to describe the structure of kelp forests along a spatial gradient spanning more than 10° of latitude. We then examined ecological goods and services provided by kelp forests, including elevated secondary production, nutrient cycling, energy capture and flow, coastal defense, direct applications, and biodiversity repositories, before discussing current and future threats posed to kelp forests and identifying key knowledge gaps. Recent evidence unequivocally demonstrates that the structure of kelp forests in the NE Atlantic is changing in response to climate- and non-climate-related stressors, which will have major implications for the structure and functioning of coastal ecosystems. However, kelp-dominated habitats along much of the NE Atlantic coastline have been chronically understudied over recent decades in comparison with other regions such as Australasia and North America. The paucity of field-based research currently impedes our ability to conserve and manage these important ecosystems. Targeted observational and experimental research conducted over large spatial and temporal scales is urgently needed to address these knowledge gaps. PMID:24198956

Bacterial pneumonia complicating influenza is well-recognized as a severe manifestation of influenza, accounting for a substantial number of deaths from the 1918 influenza pandemic. Influenza-associated bacterial pneumonia remains a major contributor to the burden of influenza, and poses new challenges as antibiotic-resistant organisms such as methicillin-resistant Staphylococcus aureus spread. We provide an overview of the current state of knowledge of the epidemiology and co-pathogenesis of influenza-associated bacterial pneumonia, and outline management approaches and their limitations. We review preventative measures and discuss implications for pandemic planning. Knowledge gaps are underscored and future research directions are proposed.

Members of the Deaf community report language and cultural barriers to accessing health information and care. This study evaluated whether an ovarian cancer education video in American Sign Language with English captioning and voiceover could close the anticipated knowledge gap between Deaf and hearing women’s cancer knowledge. Consented Deaf (n = 55) and hearing (n = 52) women’s General, Ovarian, and Total Cancer Knowledge were assessed before and after viewing the video. At baseline, hearing women demonstrated significantly higher General, Ovarian, and Total Cancer Knowledge scores than Deaf women. By the post-test, all of Deaf women’s knowledge scores had increased, closing the baseline gap. However, hearing women’s post-video knowledge had also increased, thereby creating a new knowledge gap. The ovarian cancer education video offers an effective method to increase ovarian and general cancer knowledge for Deaf and hearing women. PMID:23975658

This paper explores the possibility of integrating knowledge mapping into a conceptual framework that could serve as a tool for understanding the many complex processes, resources and people involved in a health system, and for identifying potential gaps within knowledge translation processes in order to address them. After defining knowledge mapping, this paper presents various examples of the application of this process in health, before looking at the steps that need to be taken to identify potential gaps, to determine to what extent these gaps affect the knowledge translation process and to establish their cause. This is followed by proposals for interventions aimed at strengthening the overall process. Finally, potential limitations on the application of this framework at the country level are addressed.

Nutritional issues among older adults with cancer are an understudied area of research despite significant prognostic implications for treatment side effects, cancer-specific mortality, and overall survival. In May of 2015, the National Cancer Institute and the National Institute on Aging co-sponsored a conference focused on future directions in geriatric oncology research. Nutritional research among older adults with cancer was highlighted as a major area of concern as most nutritional cancer research has been conducted among younger adults, with limited evidence to guide the care of nutritional issues among older adults with cancer. Cancer diagnoses among older adults are increasing, and the care of the older adult with cancer is complicated due to multimorbidity, heterogeneous functional status, polypharmacy, deficits in cognitive and mental health, and several other non-cancer factors. Due to this complexity, nutritional needs are dynamic, multifaceted, and dependent on the clinical scenario. This manuscript outlines the proceedings of this conference including knowledge gaps and recommendations for future nutritional research among older adults with cancer. Three common clinical scenarios encountered by oncologists include (1) weight loss during anti-cancer therapy, (2) malnutrition during advanced disease, and (3) obesity during survivorship. In this manuscript, we provide a brief overview of relevant cancer literature within these three areas, knowledge gaps that exist, and recommendations for future research. PMID:27197919

The objective of this study was to identify trends and gaps in the field of implementation science in genomic medicine. We conducted a literature review using the Centers for Disease Control and Prevention's Public Health Genomics Knowledge Base to examine the current literature in the field of implementation science in genomic medicine. We selected original research articles based on specific inclusion criteria and then abstracted information about study design, genomic medicine, and implementation outcomes. Data were aggregated, and trends and gaps in the literature were discussed. Our final review encompassed 283 articles published in 2014, the majority of which described uptake (35.7%, n = 101) and preferences (36.4%, n = 103) regarding genomic technologies, particularly oncology (35%, n = 99). Key study design elements, such as racial/ethnic composition of study populations, were underreported in studies. Few studies incorporated implementation science theoretical frameworks, sustainability measures, or capacity building. Although genomic discovery provides the potential for population health benefit, the current knowledge base around implementation to turn this promise into a reality is severely limited. Current gaps in the literature demonstrate a need to apply implementation science principles to genomic medicine in order to deliver on the promise of precision medicine.Genet Med advance online publication 12 January 2017.

Early detection and intervention seem to improve development in autistic children, and teachers form an important part of their early social environment. The objective of this study was to assess baseline knowledge and misconceptions regarding autism among school teachers and evaluate factors influencing their knowledge. This is a cross-sectional survey enrolling primary school teachers using a self-administered questionnaire. Seventy-three teachers (mean age of 34 years, 66% females) responded. Gaps in awareness and knowledge were found. About 52 (71.2%) teachers identified themselves as having some knowledge about autism, with 23 (44.2%) among this group understanding autism as a neurological/mental disorder. The majority (73.1%) believe that special education is a helpful intervention. The only significant factor that influenced knowledge among teachers was attendance of behavioral classes ( P = 0.01). Results suggest that teachers have an inadequate understanding of autism due to several misconceptions. This calls for increased education of teachers with regard to autism and other childhood disorders.

Membrane bioreactor technology exists for a couple of decades, but has not yet overwhelmed the market due to some serious drawbacks of which operational cost due to fouling is the major contributor. Knowledge buildup and optimisation for such complex systems can significantly benefit from mathematical modelling. In this paper, the vast literature on modelling MBR biokinetics and filtration is critically reviewed. It was found that models cover the wide range of empirical to detailed mechanistic descriptions and have mainly been used for knowledge development and to a lesser extent for system optimisation/control. Moreover, studies are still predominantly performed at lab or pilot scale. Trends are discussed, knowledge gaps identified and interesting routes for further research suggested.

Factor, Elisa Monette R; Matienzo, Evangeline T; de Guzman, Allan B

2017-10-01

Previous studies suggest that theory-practice gap has remained to be a formidable task and a challenge to the nursing profession. While efforts to understand the nature and dynamics of theory-practice gap have been undertaken across the globe, a dearth in literature exists in the context of a developing country like the Philippines. Seemingly, no research has ventured yet to explore the theory-practice gap experiences of Filipino student nurses. Hence, the major intent of this qualitative investigation is to describe and capture how theory-practice gap is viewed by a select group of senior nursing students (n=10) in a comprehensive university in the Philippines. From the thickness and richness of the descriptions of the field text gathered in this study, an interesting conceptualization labeled as the Theory-Practice Gap Deficit Triad which consists of (a) structural, (b) pedagogical, and (c) relational deficits was emerged. Interestingly, the said model describes a clear intersection of the various concerns and dilemmas encountered by student nurses in their clinical exposures. Findings of this paper are valuable inputs to nursing educators, practitioners, and administrators in initiating realignment efforts geared toward developing nurses whose knowledge, skills and attitudes are responsive to the ever changing professional practice landscape.

"Prince Charming Syndrome?" Gender gap in preferences for defined contribution pensions in Japan.

PubMed

Watanabe, Satoshi P

2017-01-01

Using survey data collected by the Japan Institute of Life Insurance in 2002, this study finds that a significant gender gap existed in defined contribution (DC) pension knowledge among workers employed at small- to medium-sized private firms in Japan. Even with similar DC knowledge, however, men and women reveal different preferences for DC pensions, indicating that their perceptional responses may widely differ from actual behaviors. Apart from the knowledge gap, the result shows evidence of the Prince Charming Syndrome among female employees as a significant source of the gender gap in DC participation rates. Among corporate pension-covered employees, the gender difference in the efficacy of DC portability is a more significant gap-generating factor. DC tax advantage is particularly favored by pension-covered female employees over male counterparts, reducing the DC preference gap. No similar evidence is found for employees with no corporate pension coverage.

To investigate the use of constraint-induced movement therapy (CIMT) in Canadian neurological occupational and physical therapy. An online survey was completed by occupational and physical therapists practising in Canadian adult neurological rehabilitation. We measured participants' practices, perceptions, and opinions in relation to their use of CIMT in clinical practice. A total of 338 surveys were returned for a 13% response rate; 92% of respondents knew of CIMT, and 43% reported using it. The majority (88%) of respondents using CIMT employed a non-traditional protocol. Self-rating of level of CIMT knowledge was found to be a significant predictor of CIMT use (p≤0.001). Commonly identified barriers to use included "patients having cognitive challenges that prohibit use of this treatment" and "lack of knowledge regarding treatment." Although the majority of respondents knew about CIMT, less than half reported using it. Barriers to CIMT use include lack of knowledge about the treatment and institutional resources to support its use. Identifying and addressing barriers to CIMT use-for example, by using continuing professional education to remediate knowledge gaps or developing new protocols that require fewer institutional resources-can help improve the feasibility of CIMT, and thus promote its clinical application.

Aim To investigate primary health care (PHC) physicians' attitudes to statistics, their self-reported knowledge level, and their perceived training needs in statistics. In spite of realization of the importance of statistics, inadequacies in physicians' knowledge and skills have been found, underscoring the need for in-service training. Understanding physicians' attitudes to statistics is vital in planning statistics training. The study was based on theory of planned behavior. A cross-sectional survey of all PHC physicians was conducted in Qassim province, from August to October 2014. Attitudes to statistics were determined by a self-administered questionnaire. The attitudes were assessed on four subscales including general perceptions; perceptions of knowledge and training; perceptions of statistics and evidence-based medicine; and perceptions of future learning. Findings Of 416 eligible participants, 338 (81.25%) responded to the survey. On a scale of 1-10, the majority (73.6%) of the participants self-assessed their level of statistics knowledge as five or below. The attitude scores could have a minimum of 20 and a maximum of 100, with higher scores showing a positive attitude. The participants showed a positive attitude with the mean score of 71.14 (±7.73). Out of the four subscales, 'perceptions of statistics and evidence-based medicine' subscale scored the highest, followed by 'perceptions of future learning'. PHC physicians have a positive attitude to statistics. However, they realize their gaps in knowledge in statistics, and are keen to fill these gaps. Statistics training, resulting in improved statistics knowledge is expected to lead to clinical care utilizing evidence-based medicine, and thus improvement to health care services.

Helminths are multicellular parasitic worms that comprise a major class of human pathogens and cause an immense amount of suffering worldwide. Helminths possess an abundance of complex and unique glycoconjugates that interact with both the innate and adaptive arms of immunity in definitive and intermediate hosts. These glycoconjugates represent a major untapped reservoir of immunomodulatory compounds, which have the potential to treat autoimmune and inflammatory disorders, and antigenic glycans, which could be exploited as vaccines and diagnostics. This review will survey current knowledge of the interactions between helminth glycans and host immunity and highlight the gaps in our understanding which are relevant to advancing therapeutics, vaccine development, and diagnostics.

Worldwide, there is a consensus that parents must be involved in children's HIV/AIDS education. However, there is little evidence that speaks to this advocacy for improving adolescent health. This study developed and tested four hypotheses about (i) the relationship between parents' and adolescents' knowledge of HIV/AIDS transmission routes and prevention strategies conditional upon (ii) parents' gender, (iii) communication about sexuality, and (iv) the parent-adolescent education gap. The sample consisted of 306 parent-adolescent dyads from the 2002 Cameroon Family and Health Survey. Adolescents were aged 12-19 years. Overall, fifteen items about HIV/AIDS transmission routes and prevention strategies were analysed. Descriptive results showed that parents fared better than adolescents regardless of the AIDS fact considered. An exception was the correct use of condoms (parents 57% vs adolescents 61%). The generation gap probably explains this result: parents are more conservative, reluctant and distant from condoms compared with adolescents, who are more receptive and open to discussing sex with peers. Multivariate ordered logistic regressions showed a significant positive effect of parents' HIV/AIDS knowledge on adolescents' HIV/AIDS knowledge, thus supporting the main hypothesis of direct parental influences. Parent-adolescent communication about sexuality showed positive and significant effects on adolescents' HIV/AIDS knowledge, suggesting an 'enhancing effect' when combined with the effect of parents' HIV/AIDS knowledge. Against the background that parents in sub-Saharan Africa do not teach their children about sexuality, the study demonstrated that families can play an important role in HIV/AIDS education. These findings have major implications for HIV/AIDS interventions involving adolescents, parents or both, in fostering accurate HIV/AIDS knowledge among adolescents, which could lead to protective sexual behaviours.

Pregnant adolescents are a high-risk population for suicide. However, a knowledge gap still exists on how sexual and religious knowledge, attitudes and practices (KAP) influence suicidal ideation (SI) in teenage pregnancy. We aim to explore the interplay between psychiatric diagnoses, sociodemographic factors and KAP of sexual and religious issues as risk factors of SI among 114 pregnant Malaysian adolescents from 6 rehabilitation centers and a tertiary hospital. Single sexual partner was an independent predictor of SI, suggesting the role of less sexual experience as a risk factor for SI after controlling for major depression. Participants who were unsure versus those who agreed with the statement that most religions' viewed sex outside marriage as wrong had a lower risk of SI after controlling for major depression. Pregnant adolescents with a single sexual partner were significantly associated with current SI. Ambivalence towards religious prohibitions on premarital sex may protect against suicidal ideation.

Needham, Dale M

2010-07-01

A large gap exists between the completion of clinical research demonstrating the benefit of new treatment interventions and improved patient outcomes resulting from implementation of these interventions as part of routine clinical practice. This gap clearly affects patient safety and quality of care. Knowledge translation is important for addressing this gap, but evaluation of the most appropriate and effective knowledge translation methods is still ongoing. Through describing one model for knowledge translation and an example of its implementation, insights can be gained into systematic methods for advancing the implementation of evidence-based interventions to improve safety, quality, and patient outcomes.

Suva (Swiss National Accident Insurance Fund) is the most important carrier of obligatory accident insurance in Switzerland. Its medical division supports doctors working in inpatient and outpatient care with comprehensive case management and with conciliar advice. The Suva hospitals provide inpatient rehabilitation. In 2002, Suva started the InWiM project. InWiM is an acronym and stands for "Integrierte Wissensbasen der Medizin", which can be translated as "Integrated Knowledge Bases in Medicine". Information retrieval within InWiM is achieved by means of the MeSH Index (Medical Subject Headings), the thesaurus of the United States National Library of Medicine (NLM). InWiM has now been extended towards the management not only of publications but also of areas where sound knowledge is missing, so called "knowledge gaps": Knowledge gaps are indexed with MeSH terms in a similar way to publications. This improves knowledge management: In particular it is possible to search and find knowledge gaps and solutions covering the same or a similar topic, thus allowing adequate collating and it prevents duplication of work. Furthermore, literature search strategies for the NML are predefined and do not need every time to be reinvented from scratch.

UTI is a well known entity amongst young girls, and the majority of girls have recurrent infections within one year. Anything that disturbs the usual vaginal environment would result in conditions favouring the production of unwanted microorganisms leading to infections of this very sensitive area. Studies have shown that, there is an evident relation of UTI's among students and practices of personal hygiene. To determine association between the behavioural risk factors and UTI among nursing girls. The present study was undertaken amongst unmarried nursing students of a Medical College Hospital. A predesigned pretested questionnaire was used to know the personal hygiene of students and to find out its association with UTI in the last three months. Chi-square test was used to analyse the data. A significant association was observed between perineal hygiene and UTI. The major risk factors of UTI identified were incorrect perineal washing technique, use of synthetic/silk innerwears, not sundrying the innerwears, improper menstrual hygiene. There are still major gaps in the knowledge regarding causation of UTI among the nursing students. This calls for an urgent need for educational talks periodically addressing these gaps.

A major knowledge gap exists on how eruptive compositions of a single martian volcanic province change over time. Here we seek to fill that gap by assessing the compositional evolution of Elysium, a major martian volcanic province. A unique geochemical signature overlaps with the southeastern flows of this volcano, which provides the context for this study of variability of martian magmatism. The southeastern lava fields of Elysium Planitia show distinct chemistry in the shallow subsurface (down to several decimeters) relative to the rest of the martian mid-to-low latitudes (average crust) and flows in northwest Elysium. By impact crater counting chronology we estimated the age of the southeastern province to be 0.85 ± 0.08 Ga younger than the northwestern fields. This study of the geochemical and temporal differences between the NW and SE Elysium lava fields is the first to demonstrate compositional variation within a single volcanic province on Mars. We interpret the geochemical and temporal differences between the SE and NW lava fields to be consistent with primary magmatic processes, such as mantle heterogeneity or change in depth of melt formation within the martian mantle due to crustal loading.

Fetal alcohol spectrum disorder in Africa.

Adnams, Colleen M

2017-03-01

This review aims to summarize data published in the scientific literature and available on official websites on fetal alcohol spectrum disorder (FASD) in Africa. There is a paucity of published literature and evidence-based information on prenatal exposure to alcohol in the African continent and the majority of the continent's literature on FASD emanates from South Africa. A small number of scientific publications document FASD and drinking in pregnancy in other Sub-Saharan African countries and these findings provide evidence that FASD occurs across the continent. Further evidence shows that the world's highest reported rates of FASD occur in South Africa and that this confers a significant public health and neurodevelopmental disability burden on the region. There is an established body of epidemiological, diagnostic, neurobehavioral and neuroscientific knowledge from studies in South Africa. Universal and indicated case method preventions are effective in reducing maternal alcohol consumption in high-risk areas. Throughout Africa, a policy and service implementation gap exists that impedes translation of generated knowledge into effective prevention and intervention strategies. FASD is likely a widely occurring and largely unrecognized neurodevelopmental disability in Africa. A key future direction for global agencies and research partnerships is to collaboratively address evidence gaps and knowledge translation through scalable approaches and strategies that aim to ameliorate the burden of FASD in African and other countries.

Leadership in Nursing Homes: Directors of Nursing Aligning Practice With Regulations.

Nursing homes use team nursing, with minimal RN presence, leaving the majority of direct care to licensed practical/vocational nurses (LPNs/LVNs) and unlicensed assistive personnel (UAP), including medication aides. The current article describes challenges faced by nursing home directors of nursing (DONs) leading and managing a team nursing approach, including consideration of scope of practice, delegation and supervision regulations, and related policy implications. A secondary data analysis was performed of qualitative data from a study to develop and test DON guidelines for delegation in nursing home practice. A convenience sample (N = 29) of current or previous DONs and other nursing home leaders with knowledge and expertise in the DON role participated in in-depth, guided interviews. The findings highlight a core concern to nursing licensure policy and regulation: knowledge and practice gaps related to scope of practice and delegation and supervision among DONs, RNs, and LPNs/LVNs, as well as administrators, and the role of nursing leaders in supporting appropriate delegation practices. The findings offer directions for research and practice in addressing challenges in aligning team nursing practices with regulatory standards as well as the related gaps in knowledge among DONs, administrators, and nursing staff.

Abebe, Dawit Shawel; Lien, Lars; Hjelde, Karin Harsløf

2014-02-01

Mental health problems have been regarded as one of the main public health challenges of immigrants in several countries. Understanding and generating research-based knowledge on immigrant health problems is highly relevant for planning preventive interventions, as well as guiding social and policy actions. This review aims to map the available knowledge on immigrants' mental health status and its associated risk factors in Norway. The reviewed literature about mental health problems among immigrant populations in Norway was found through databases, such as PUBMED, EMBASE, PsychINFO and MEDLINE. About 41 peer-reviewed original articles published since 1990s were included. In the majority of the studies, the immigrant populations, specifically adult immigrants from low and middle income countries, have been found with a higher degree of mental health problems compared to Norwegians and the general population. Increased risk for mental illness is primarily linked to a higher risk for acculturative stress, poor social support, deprived socioeconomic conditions, multiple negative life events, experiences of discrimination and traumatic pre-migration experiences. However, research in this field has been confronted by a number of gaps and methodological challenges. The available knowledge indicates a need for preventive interventions. Correspondingly, it strongly recommends a comprehensive research program that addresses gaps and methodological challenges.

Climate change, air pollution and human health in Sydney, Australia: A review of the literature

Dean, Annika; Green, Donna

2018-05-01

Sydney is Australia’s largest city and is growing rapidly. Although Sydney’s air quality is relatively good compared to the major cities in many industrialised countries, particulate matter (PM) and ozone (O3) occasionally exceed the national health standards and are the cause of premature mortalities and hospital admissions. Numerous studies from overseas (e.g. North America and continental Europe) suggest that climate change may impact air quality to the detriment of human health. There is limited knowledge about how climate change may impact air quality in Sydney. This study reviews the available literature on the impacts of climate change on air quality related health impacts in Sydney to identify knowledge and research gaps. Where no studies are available for Sydney, it draws on relevant studies from other Australian cities and overseas. Our findings summarise what is known about how climate change may impact air quality in Sydney and where research gaps exist. This approach can facilitate research agendas, policies and planning strategies that mitigate public health impacts and tackle climate change and air pollution in a coordinated way.

The Trauma Hemostasis and Oxygenation Research Network held its third annual Remote Damage Control Resuscitation Symposium in June 2013 in Bergen, Norway. The Trauma Hemostasis and Oxygenation Research Network is a multidisciplinary group of investigators with a common interest in improving outcomes and safety in patients with severe traumatic injury. The network's mission is to reduce the risk of morbidity and mortality from traumatic hemorrhagic shock, in the prehospital phase of resuscitation through research, education, and training. The concept of remote damage control resuscitation is in its infancy, and there is a significant amount of work that needs to be done to improve outcomes for patients with life-threatening bleeding secondary to injury. The prehospital phase of resuscitation is critical in these patients. If shock and coagulopathy can be rapidly identified and minimized before hospital admission, this will very likely reduce morbidity and mortality. This position statement begins to standardize the terms used, provides an acceptable range of therapeutic options, and identifies the major knowledge gaps in the field.

Teaching critical appraisal skills for nursing research.

PubMed

Jones, Sandra C; Crookes, Patrick A; Johnson, Keryn M

2011-09-01

Evidence-based practice is a major focus in nursing, yet the literature continues to document a research-practice gap. Reasons for this gap stem partly from a lack of skills to critique and synthesize the literature, a lack of search skills and difficulty in understanding research articles, and limited knowledge of research by nursing professionals. An innovative and quality driven subject to improve critical appraisal and critical thinking skills was developed for the School of Nursing, Midwifery and Indigenous Health at the University of Wollongong, based on formative research with postgraduate students and supervisors. Through face-to-face and online teaching modules students worked through a structured process of analysing the key aspects of published papers using structured analysis tools for each study design. Pre and post surveys of students found improvements in perceived knowledge of all key skills of critical appraisal. External independent evaluation determined that it was a high quality subject showing many hallmarks of good assessment practice and good practice in use of information and communication technology (ICT) in support of the learning outcomes.

The World Health Organization (WHO) declared the Ebola virus disease (EVD) epidemic to be a public health emergency of international concern. Healthcare workers (HCWs) are at the highest risk of infection, as they may come into contact with patients' blood or fluids. This study was conducted to assess knowledge and attitudes of HCWs towards EVD in India. A descriptive, cross-sectional study was conducted in a multispecialty public sector referral hospital of Telangana, India. Knowledge and attitude of HCWs were evaluated using a pre-validated questionnaire. A sample of 278 participants was selected to participate in this study. The Chi-squared test was used to assess the relationship between attitudes and demographic characteristics. Logistic regression was used examine the association between knowledge and study variables. Of 257 participants who responded (92.4% response rate), 157 (61.1%) were females. The majority of the respondents were physicians (n = 117, 45.5%). Radio and television were the major sources of information about EVD reported by participants (89%). Overall knowledge of HCWs was poor (mean knowledge score: 6.57 ± 2.57). Knowledge of physicians and experienced workers (≥ 10 years) was significantly higher than their respective groups. The overall attitude of the participants was positive (mean attitude score: 1.62 ± 0.57). Significant positive correlations between knowledge and attitude were observed. The findings indicate that participants lack basic understanding of EVD. We recommend future studies be conducted across India to identify and subsequently bridge the knowledge gaps among HCWs.

Understanding the Knowledge Gap Experienced by U.S. Safety Net Patients in Teleretinal Screening.

2016-01-01

Safety-net patients' socioeconomic barriers interact with limited digital and health literacies to produce a "knowledge gap" that impacts the delivery of healthcare via telehealth technologies. Six focus groups (2 African- American and 4 Latino) were conducted with patients who received teleretinal screening in a U.S. urban safety-net setting. Focus groups were analyzed using a modified grounded theory methodology. Findings indicate that patients' knowledge gap is primarily produced at three points during the delivery of care: (1) exacerbation of patients' pre-existing personal barriers in the clinical setting; (2) encounters with technology during screening; and (3) lack of follow up after the visit. This knowledge gap produces confusion, potentially limiting patients' perceptions of care and their ability to manage their own care. It may be ameliorated through delivery of patient education focused on both disease pathology and specific role of telehealth technologies in disease management.

The purpose of this study is to explore the perceptions mathematics students have of the knowledge and skills they develop throughout their programme of study. It addresses current concerns about the employability of mathematics graduates by contributing much needed insight into how degree programmes are developing broader learning outcomes for students majoring in mathematics. Specifically, the study asked students who were close to completing a mathematics major (n = 144) to indicate the extent to which opportunities to develop mathematical knowledge along with more transferable skills (communication to experts and non-experts, writing, working in teams and thinking ethically) were included and assessed in their major. Their perceptions were compared to the importance they assign to each of these outcomes, their own assessment of improvement during the programme and their confidence in applying these outcomes. Overall, the findings reveal a pattern of high levels of students' agreement that these outcomes are important, but evidence a startling gap when compared to students' perceptions of the extent to which many of these - communication, writing, teamwork and ethical thinking - are actually included and assessed in the curriculum, and their confidence in using such learning.

The incidence and prevalence of most cardiovascular disorders increase with age, and cardiovascular disease is the leading cause of death and major disability in adults ≥75 years of age; however, despite the large impact of cardiovascular disease on quality of life, morbidity, and mortality in older adults, patients aged ≥75 years have been markedly underrepresented in most major cardiovascular trials, and virtually all trials have excluded older patients with complex comorbidities, significant physical or cognitive disabilities, frailty, or residence in a nursing home or assisted living facility. As a result, current guidelines are unable to provide evidence-based recommendations for diagnosis and treatment of older patients typical of those encountered in routine clinical practice. The objectives of this scientific statement are to summarize current guideline recommendations as they apply to older adults, identify critical gaps in knowledge that preclude informed evidence-based decision making, and recommend future research to close existing knowledge gaps. To achieve these objectives, we conducted a detailed review of current American College of Cardiology/American Heart Association and American Stroke Association guidelines to identify content and recommendations that explicitly targeted older patients. We found that there is a pervasive lack of evidence to guide clinical decision making in older patients with cardiovascular disease, as well as a paucity of data on the impact of diagnostic and therapeutic interventions on key outcomes that are particularly important to older patients, such as quality of life, physical function, and maintenance of independence. Accordingly, there is a critical need for a multitude of large population-based studies and clinical trials that include a broad spectrum of older patients representative of those seen in clinical practice and that incorporate relevant outcomes important to older patients in the study design. The results of these studies will provide the foundation for future evidence-based guidelines applicable to older patients, thereby enhancing patient-centered evidence-based care of older people with cardiovascular disease in the United States and around the world. © 2016 by the American Heart Association, Inc., the American College of Cardiology Foundation, and the American Geriatrics Society.

For cDNA array methods that depend on imaging of a radiolabel, we show that bleedover of one spot onto another, due to the gap between the array and the imaging media, can be a major problem. The images can be sharpened, however, using a blind convolution method based on the EM algorithm. The sharpened images look like a set of donuts, which concurs with our knowledge of the spotting process. Oversharpened images are actually useful as well, in locating the centers of each spot.

Surgery is a cornerstone of cancer treatment, but significant differences in the quality of surgery have been reported. Surgical process improvement tools (spits) modify the processes of care as a means to quality improvement (qi). We were interested in developing spits in the area of gastrointestinal (gi) cancer surgery. We report the recommendations of an expert panel held to define quality gaps and establish priority areas that would benefit from spits. The present study used the knowledge-to-action cycle was as a framework. Canadian experts in qi and in gi cancer surgery were assembled in a nominal group workshop. Participants evaluated the merits of spits, described gaps in current knowledge, and identified and ranked processes of care that would benefit from qi. A qualitative analysis of the workshop deliberations using modified grounded theory methods identified major themes. The expert panel consisted of 22 participants. Experts confirmed that spits were an important strategy for qi. The top-rated spits included clinical pathways, electronic information technology, and patient safety tools. The preferred settings for use of spits included preoperative and intraoperative settings and multidisciplinary contexts. Outcomes of interest were cancer-related outcomes, process, and the technical quality of surgery measures. Surgical process improvement tools were confirmed as an important strategy. Expert panel recommendations will be used to guide future research efforts for spits in gi cancer surgery.

Nutritional issues among older adults with cancer are an understudied area of research despite significant prognostic implications for treatment side effects, cancer-specific mortality, and overall survival. In May of 2015, the National Cancer Institute and the National Institute on Aging co-sponsored a conference focused on future directions in geriatric oncology research. Nutritional research among older adults with cancer was highlighted as a major area of concern as most nutritional cancer research has been conducted among younger adults, with limited evidence to guide the care of nutritional issues among older adults with cancer. Cancer diagnoses among older adults are increasing, and the care of the older adult with cancer is complicated due to multimorbidity, heterogeneous functional status, polypharmacy, deficits in cognitive and mental health, and several other non-cancer factors. Due to this complexity, nutritional needs are dynamic, multifaceted, and dependent on the clinical scenario. This manuscript outlines the proceedings of this conference including knowledge gaps and recommendations for future nutritional research among older adults with cancer. Three common clinical scenarios encountered by oncologists include (1) weight loss during anti-cancer therapy, (2) malnutrition during advanced disease, and (3) obesity during survivorship. In this manuscript, we provide a brief overview of relevant cancer literature within these three areas, knowledge gaps that exist, and recommendations for future research.

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

One of the fundamental issues in bridging the gap between the proliferation of Content-Based Image Retrieval (CBIR) systems in the scientific literature and the deficiency of their usage in medical community is based on the characteristic of CBIR to access information by images or/and text only. Yet, the way physicians are reasoning about patients leads intuitively to a case representation. Hence, a proper solution to overcome this gap is to consider a CBIR approach inspired by Case-Based Reasoning (CBR), which naturally introduces medical knowledge structured by cases. Moreover, in a CBR system, the knowledge is incrementally added and learned. The purpose of this study is to initiate a translational solution from CBIR algorithms to clinical practice, using a CBIR/CBR hybrid approach. Therefore, we advance the idea of a translational incremental similarity-based reasoning (TISBR), using combined CBIR and CBR characteristics: incremental learning of medical knowledge, medical case-based structure of the knowledge (CBR), image usage to retrieve similar cases (CBIR), similarity concept (central for both paradigms). For this purpose, three major axes are explored: the indexing, the cases retrieval and the search refinement, applied to Breast Cancer Grading (BCG), a powerful breast cancer prognosis exam. The effectiveness of this strategy is currently evaluated over cases provided by the Pathology Department of Singapore National University Hospital, for the indexing. With its current accuracy, TISBR launches interesting perspectives for complex reasoning in future medical research, opening the way to a better knowledge traceability and a better acceptance rate of computer-aided diagnosis assistance among practitioners.

Knowledge translation is an essential and emerging arena in healthcare research. It is the process of aiding the application of research knowledge into clinical practice or policymaking. Individuals at all levels of the health care system, including patients, healthcare professionals, and policymakers, are affected by the gaps that exist between research evidence and practice; the process of knowledge translation plays a role in bridging these gaps and incorporating high-quality clinical research into decision-making. Cardiovascular disease (CVD) management is a crucial area of healthcare where information gaps are known to exist. Although Japan has one of the lowest risks and mortality rates from CVDs, an increasing trend of cardiovascular incidence and changes in the risk factor conditions have been observed in recent years. This article provides an overview of knowledge translation and its importance in the cardiovascular health of the Japanese population, and describes the key steps of a typical knowledge translation strategy.

One of the major challenges facing current media management systems and the related applications is the so-called "semantic gap" between the rich meaning that a user desires and the shallowness of the content descriptions that are automatically extracted from the media. In this paper, we address the problem of bridging this gap in the sports domain. We propose a general framework for indexing and summarizing sports broadcast programs. The framework is based on a high-level model of sports broadcast video using the concept of an event, defined according to domain-specific knowledge for different types of sports. Within this general framework, we develop automatic event detection algorithms that are based on automatic analysis of the visual and aural signals in the media. We have successfully applied the event detection algorithms to different types of sports including American football, baseball, Japanese sumo wrestling, and soccer. Event modeling and detection contribute to the reduction of the semantic gap by providing rudimentary semantic information obtained through media analysis. We further propose a novel approach, which makes use of independently generated rich textual metadata, to fill the gap completely through synchronization of the information-laden textual data with the basic event segments. An MPEG-7 compliant prototype browsing system has been implemented to demonstrate semantic retrieval and summarization of sports video.

The growth of Knowledge Economy has transformed human capital to be the vital asset in business organization of the 21st century. Arguably, due to its white-collar nature, knowledge-based industry is more favorable than traditional manufacturing business. However, over dependency on human capital can also be a major challenge as any workers will inevitably leave the company or retire. This situation will possibly create knowledge gap that may impact business continuity of the enterprise. Knowledge retention in the corporate environment has been of many research interests. Learning Management System (LMS) refers to the system that provides the delivery, assessment and management tools for an organization to handle its knowledge repository. By using the aspirations of a proven LMS implemented in an academic environment, this paper proposes LMS model that can be used to enable peer-to-peer knowledge capture and sharing in the knowledge-based organization. Cloud Enterprise Resource Planning (ERP), referred to an ERP solution in the internet cloud environment was chosen as the domain knowledge. The complexity of the Cloud ERP business and its knowledge make it very vulnerable to the knowledge retention problem. This paper discusses how the company's essential knowledge can be retained using the LMS system derived from academic environment into the corporate model.

Background Data on sociological and behavioural aspects of malaria, which is essential for an evidence-based design of prevention and control programmes, is lacking in Bangladesh. This paper attempts to fill this knowledge gap by using data from a population-based prevalence survey conducted during July to November 2007, in 13 endemic districts of Bangladesh. Methods A two-stage cluster sampling technique was used to select study respondents randomly from 30 mauzas in each district for the socio-behavioural inquiry (n = 9,750). A pre-tested, semi-structured questionnaire was used to collect data in face-to-face interview by trained interviewers, after obtaining informed consent. Results The overall malaria prevalence rate in the 13 endemic districts was found to be 3.1% by the Rapid Diagnostic Test 'FalciVax' (P. falciparum 2.73%, P. vivax 0.16% and mixed infection 0.19%), with highest concentration in the three hill districts (11%). Findings revealed superficial knowledge on malaria transmission, prevention and treatment by the respondents. Poverty and level of schooling were found as important determinants of malaria knowledge and practices. Allopathic treatment was uniformly advocated, but the 'know-do' gap became especially evident when in practice majority of the ill persons either did not seek any treatment (31%) or practiced self-treatment (12%). Of those who sought treatment, the majority went to the village doctors and drugstore salespeople (around 40%). Also, there was a delay beyond twenty-four hours in beginning treatment of malaria-like fever in more than half of the instances. In the survey, gender divide in knowledge and health-seeking behaviour was observed disfavouring women. There was also a geographical divide between the high endemic south-eastern area and the low-endemicnorth-eastern area, the former being disadvantaged with respect to different aspects of malaria studied. Conclusion The respondents in this study lacked comprehensive knowledge on different aspects of malaria, which was influenced by level of poverty and education. A gender and geographical divide in knowledge was observed disfavouring women and south-eastern area respectively. They preferred allopathic treatment for malaria, although a substantial proportion did not seek any treatment or sought self-treatment for malaria-like fever. Delay in seeking care was common. The implications of these findings for programme development are discussed. PMID:19640282

In recent years a large number of engineered nanomaterials (NMs) have been developed with promising technical benefits for consumers and medical appliances. In addition to already known potentially advantageous biological properties (antibiotic, antifungal and antiviral activity) of NMs, many new medical applications of NMs are foreseen, such as drug carriers, contrast agents, radiopharmaceuticals and many others. However, there is increasing concern about potential environmental and health effects due to NMs exposure. An increasing body of evidence suggests that NMs may trigger undesirable hazardous interactions with biological systems with potential to generate harmful effects. In this review we summarized a current state of knowledge on the proteomics approaches to nanotoxicity, including protein corona formation, in vitro and in vivo effects of exposure to NMs on proteome of different classes of organisms, from bacteria and plants to mammals. The effects of NMs on the proteome of environmentally relevant organisms are also described. Despite the benefit that development of nanotechnology may bring to the society, there are still major gaps of knowledge on the influence of nanomaterials on human health and the environment. Thus, it seems necessary to conduct further interdisciplinary research to fill the knowledge gaps in NM toxicity, using more holistic approaches than offered by conventional biological techniques. “OMICS” techniques will certainly help researchers in this field. In this paper we summarized the current stage of knowledge of the effects of nanoparticles on the proteome of different organisms, including those commonly used as an environmentally relevant indicator organisms.

The GAP between the knowledge of contraception and its actual practice is well recognized in the literature of family welfare studies. The present study assessed the relation between the level of knowledge and practice of contraception among the women and sought to explore the reasons behind the Knowledge, Attitude, and Practice - GAP (KAP GAP) regarding contraceptive users in six cities of Uttar Pradesh. Present analysis based on 17,643 currently married women aged 15 to 49. A Bivariate analysis ( χ 2 test) and a multivariable logistic regression were performed for the study. The highest percentages of respondents (women) were in the age group 35-49 (40-45 %) in all the districts considered. Knowledge of contraceptives was almost universal; tubal ligation and pill were the commonly known methods. Information about the contraceptive methods was mostly obtained through the husband. In the present study, there was a highly significant association ( p  < 0.01) of age group, educational status of respondents, the number of living children, the wealth of the respondent, media exposure and husband's education with the variable KAP GAP for all six cities. Health concern issues in all the districts were the most prominent reason for not using contraception. There differences in the socioeconomic and demographic factors exist, which lead to KAP GAP in the family planning (FP) usages. Therefore, in designing effective family planning programme, there is a need to understand the various factors which influence the practice of contraception.

In 2012, the Advisory Committee on Immunization Practices recommended 13-valent pneumococcal conjugate vaccine (PCV13) in series with 23-valent pneumococcal polysaccharide vaccine (PPSV23) for at-risk adults ≥19; in 2014, it expanded this recommendation to adults ≥65. Primary care physicians' practice, knowledge, attitudes, and beliefs regarding these recommendations are unknown. Primary care physicians throughout the U.S. were surveyed by E-mail and post from December 2015 to January 2016. Response rate was 66% (617 of 935). Over 95% of respondents reported routinely assessing adults' vaccination status and recommending both vaccines. A majority found the current recommendations to be clear (50% "very clear," 38% "somewhat clear"). Twenty percent found the upfront cost of purchasing PCV13, lack of insurance coverage, inadequate reimbursement, and difficulty determining vaccination history to be "major barriers" to giving these vaccines. Knowledge of recommendations varied, with 83% identifying the PCV13 recommendation for adults ≥65 and only 21% identifying the recommended interval between PCV13 and PPSV23 in an individual <65 at increased risk. Almost all surveyed physicians reported recommending both pneumococcal vaccines, but a disconnect seems to exist between perceived clarity and knowledge of the recommendations. Optimal implementation of these recommendations will require addressing knowledge gaps and reported barriers. © Copyright 2018 by the American Board of Family Medicine.

ABSTRACT Purpose: To investigate the use of constraint-induced movement therapy (CIMT) in Canadian neurological occupational and physical therapy. Method: An online survey was completed by occupational and physical therapists practising in Canadian adult neurological rehabilitation. We measured participants' practices, perceptions, and opinions in relation to their use of CIMT in clinical practice. Results: A total of 338 surveys were returned for a 13% response rate; 92% of respondents knew of CIMT, and 43% reported using it. The majority (88%) of respondents using CIMT employed a non-traditional protocol. Self-rating of level of CIMT knowledge was found to be a significant predictor of CIMT use (p≤0.001). Commonly identified barriers to use included “patients having cognitive challenges that prohibit use of this treatment” and “lack of knowledge regarding treatment.” Conclusions: Although the majority of respondents knew about CIMT, less than half reported using it. Barriers to CIMT use include lack of knowledge about the treatment and institutional resources to support its use. Identifying and addressing barriers to CIMT use—for example, by using continuing professional education to remediate knowledge gaps or developing new protocols that require fewer institutional resources—can help improve the feasibility of CIMT, and thus promote its clinical application.

University students generally make independent decisions regarding food choices. Current research about knowledge of Australian Dietary Guidelines (ADG), sources of nutrition information and influences on food choices for this group is scarce. Qualitative data was collected from gender separated focus groups comprising four female (n=31) and four male (n=18) to identify: knowledge of ADG, sources of nutrition information; factors that influence food choices; perceived relevant nutrition messages and how best to deliver them. Gaps in knowledge were identified particularly regarding number of serves and serving size for food groups. Social media was the most commonly reported source of knowledge. Social media was also a major influence on food choice due to its impact on body ideals. Current health promotion nutrition messages were perceived irrelevant given the focus on long-term health risks. Health and adhering to the ADG were not identified as important. The desire to look a particular way was the major influence on food choices. SO WHAT?: While there is an awareness of ADG, our participants made a deliberate decision not to follow them. This provides a challenge for developing relevant preventive health messages for this target audience. This article is protected by copyright. All rights reserved.

Giving what one should: explanations for the knowledge-behavior gap for altruistic giving.

Blake, Peter R

2018-04-01

Several studies have shown that children struggle to give what they believe that they should: the so-called knowledge-behavior gap. Over a dozen recent Dictator Game studies find that, although young children believe that they should give half of a set of resources to a peer, they typically give less and often keep all of the resources for themselves. This article reviews recent evidence for five potential explanations for the gap and how children close it with age: self-regulation, social distance, theory of mind, moral knowledge and social learning. I conclude that self-regulation, social distance, and social learning show the most promising evidence for understanding the mechanisms that can close the gap. Copyright © 2017 Elsevier Ltd.

Biological invasions are a major cause of global species change. Nevertheless, knowledge about the distribution and ecology of introduced species is regionally biased, and many gaps in knowledge exist for most developing countries. To study the zoobenthos on the hard substratum of the Ilha Grande Bay, a survey was conducted on both natural and artificial substrata at three depths and seven sites. The species recorded were classified as native, cryptogenic or introduced. Multivariate analyses were conducted to assess the prevalence of introduced species in these communities and to compare the distribution of species on natural and artificial substrata of this bay to identify possible discrepancies in habitat use. Of the 61 species, 25 were cryptogenic, 10 were introduced and 26 were native. Similar numbers of introduced species were found on both natural and artificial substrata, though the community composition was significantly different between them. We also compared the species composition of the Ilha Grande Bay survey to other inventories taken around the world. The highest similarities were found between the Ilha Grande Bay inventory and the Atlantic coastal region (Tampa Bay, USA and the Gulf of Mexico), American Samoa and Pearl Harbor (USA) inventories. This study presents the first published comprehensive list of hard substratum sessile marine invertebrate species in a Brazilian bay. The high percentage of cryptogenic species reveals gaps in both zoological records and information on introduced species for the Brazilian coast. The introduced species successfully colonized different sites in the Ilha Grande Bay, including both natural and artificial substrata. In addition, we find that artificial structures may not be good surrogates for natural rocky shores and may represent an ecological threat. Comparisons with other inventories suggest a history of broad-scale invasion, though more evidence is needed to support this conclusion.

Despite considerable attention currently being given to facilitating the use of research results in public health practice, several concerns remain, resulting in the so-called know-do gap. This article aims to identify the key tensions causing the know-do gap from a broad perspective by using a systemic approach and considering the public health sector as an innovation system. An exploratory qualitative design including in-depth semi-structured interviews was used, with 33 interviewees from different actor categories in the Dutch public health innovation system. The analyses employed an innovation system matrix to highlight the principal tensions causing the know-do gap. Seven key tensions were identified, including: research priorities determined by powerful players; no consensus about criteria for knowledge quality; different perceptions about the knowledge broker role; competition engendering fragmentation; thematic funding engendering fragmentation; predominance of passive knowledge sharing; and lack of capacity among users to use and influence research. The identified tensions indicate that bridging the know-do gap requires much more than linking research to practice or translating knowledge. An innovation system perspective is crucial in providing information on the total picture of knowledge exchange within the Dutch public health sector. Such a system includes broader stakeholder involvement as well as the creation of social, economic, and contextual conditions (achieving shared visions, building networks, institutional change, removing financial and infrastructural barriers), as these create conducive factors at several system levels and induce knowledge co-creation and innovation.

Knowledge, risk perception and mitigation measures towards Ebola virus disease by potentially exposed bushmeat handlers in north-central Nigeria: Any critical gap?

The bushmeat industry has been a topic of increasing importance among public health officials for its influence on zoonotic diseases transmission, such as Ebola virus disease (EVD), a rare and severe infectious disease of humans and non-human primates. This survey assessed knowledge/awareness, risk perceptions and mitigation practices towards EVD among bushmeat handlers in north-central Nigeria. These characteristics are premise to level of preparedness against appropriate risk prevention and control. A questionnaire-based cross-sectional study was conducted between January and December 2015 on 395 bushmeat handlers. Descriptive and analytical statistical analyses were performed using Epi-Info 3.5.3 software, and p < 0.05 was considered statistical significance in all analyses. Mean age of respondents was 40.9 ± 10.7 years, and most (30.4%) of them were in the age group 40-49 years. Majority (82.8%) of them were males, while most (47.9%) do not possess formal education. Bushmeat hunters, vendors and consumers constituted 17.2%, 28.1% and 54.7% of the respondents, respectively. A majority (85.6%) of the participants had heard about EVD. Bushmeat vendors were more likely (OR 1.96; 95% CI: 1.05-3.65) to have satisfactory knowledge than the hunters. Handlers with tertiary education were more likely (OR 3.22; 95% CI: 1.56-6.67) to possess significant satisfactory knowledge/awareness about EVD. Also, vendors were more likely (OR 1.85; 95% CI: 1.01-3.42) to practice satisfactory mitigation measures than the hunters. Only handlers with tertiary education were more likely (OR 2.48; 95% CI: 1.26-4.89) to significantly practice satisfactory mitigation measures against EVD. Although most of the handlers possessed significant knowledge/awareness about EVD, few applied mitigation measures against its infection, which is the challenging gap. There is a need for collaborations between the public health, veterinary and wildlife authorities in the provision of health information to bushmeat handlers on better management of emerging and re-emerging zoonotic viral diseases of wildlife origin. © 2017 Blackwell Verlag GmbH.

Membrane bioreactor technology exists for a couple of decades, but has not yet overwhelmed the market due to some serious drawbacks of which operational cost due to fouling is the major contributor. Knowledge buildup and optimisation for such complex systems can heavily benefit from mathematical modelling. In this paper, the vast literature on hydrodynamic and integrated MBR modelling is critically reviewed. Hydrodynamic models are used at different scales and focus mainly on fouling and only little on system design/optimisation. Integrated models also focus on fouling although the ones including costs are leaning towards optimisation. Trends are discussed, knowledge gaps identified and interesting routes for further research suggested. Copyright © 2012 Elsevier Ltd. All rights reserved.

Establishing priorities for future ground based and space based materials research was a major goal of the workshop. The end product of the workshop was an assessment of the current state-of-the-art in space environmental effects on materials in order to develop a national plan for spaceflight experiments.

Toward Understanding, Managing, and Protecting Microbial Ecosystems

Microbial communities are at the very basis of life on earth, catalyzing biogeochemical reactions driving global nutrient cycles. However, unlike for plants and animals, microbial diversity is not on the biodiversity–conservation agenda. The latter, however, would imply that microbial diversity is not under any threat by anthropogenic disturbance or climate change. This maybe a misconception caused by the rudimentary knowledge we have concerning microbial diversity and its role in ecosystem functioning. This perspective paper identifies major areas with knowledge gaps within the field of environmental microbiology that preclude a comprehension of microbial ecosystems on the level we have for plants and animals. Opportunities and challenges are pointed out to open the microbial black box and to go from descriptive to predictive microbial ecology. PMID:21747797

Gaps in tuberculosis knowledge among primary health care physicians in Croatia: epidemiological study.

Jurcev Savicević, Anamarija

2009-06-01

High level of tuberculosis (TB) knowledge among physicians is important in order to achieve high case-finding and efficient case-management. Few attempts on how to measure physicians' TB knowledge and understanding of national TB guidelines in middle-TB incidence countries such as Croatia have been reported. Related surveys were carried out mostly in high or low incidence countries. The aim of this study was to investigate TB knowledge among general practitioners (GPs) and paediatricians in Split and Dalmatian County, Croatia and need for TB education through cross-sectional survey based on anonymous questionnaire sent to all of them and completed by 160 (60.8%) subjects. Although the median percentage of correct responses was not low (70.3%), several areas of concern were revealed. Particularly low knowledge about normal breathing as usual physical chest examination finding in pulmonary TB (43.1%), proper drugs combination in initial phase of treatment (35%), and duration of treatment (61.9%) were found. Need for education in TB control was reported in 87.9% of physicians. TB knowledge score was obtained by the number of correct answers to 14 selected questions and it was 8.18 +/- 1.84. Scores according to years of experience, number of treated TB patients and need for education, were not different from each other. Higher score was correlated with paediatricians (p = 0.025) and familiarity with existence of National guidelines (p = 0.002). This study showed gaps in knowledge among physicians being the cornerstone of TB control in Croatia. Given that the most successful intervention in TB control is early detection and early and appropriate treatment, efforts should be done to increase TB knowledge. Majority of participants were willing to take a part in education. This could be a good starting point for organisation of education activities as one of the approaches to reduce tuberculosis burden in middle incidence countries.

The Mission Statement document describes the results, activities, and processes used in preparing the Mission Statement, facility characteristics, and operating goals for the Engineering Test Facility (ETF). Approximately 100 engineers and scientists from throughout the US fusion program spent three days at the Knoxville Mission Workshop defining the requirements that should be met by the ETF during its operating life. Seven groups were selected to consider one major category each of design and operation concerns. Each group prepared the findings of the assigned area as described in the major sections of this document. The results of the operations discussed mustmore » provide the data, knowledge, experience, and confidence to continue to the next steps beyond the ETF in making fusion power a viable energy option. The results from the ETF mission (operations are assumed to start early in the 1990's) are to bridge the gap between the base of magnetic fusion knowledge at the start of operations and that required to design the EPR/DEMO devices.« less

Although numerous leadership development programs (LDPs) exist in health care, no programs have been specifically designed to meet the needs of surgeons. This study aimed to elicit practicing surgeons' motivations and desired goals for leadership training to design an evidence-based LDP in surgery. At a large academic health center, we conducted semistructured interviews with 24 surgical faculty members who voluntarily applied and were selected for participation in a newly created LDP. Transcriptions of the interviews were analyzed using analyst triangulation and thematic coding to extract major themes regarding surgeons' motivations and perceived needs for leadership knowledge and skills. Themes from interview responses were then used to design the program curriculum specifically to meet the leadership needs of surgical faculty. Three major themes emerged regarding surgeons' motivations for seeking leadership training: (1) Recognizing key gaps in their formal preparation for leadership roles; (2) Exhibiting an appetite for personal self-improvement; and (3) Seeking leadership guidance for career advancement. Participants' interviews revealed four specific domains of knowledge and skills that they indicated as desired takeaways from a LDP: (1) leadership and communication; (2) team building; (3) business acumen/finance; and (4) greater understanding of the health care context. Interviews with surgical faculty members identified gaps in prior leadership training and demonstrated concrete motivations and specific goals for participating in a formal leadership program. A LDP that is specifically tailored to address the needs of surgical faculty may benefit surgeons at a personal and institutional level. Copyright © 2016 Elsevier Inc. All rights reserved.

The impact of retirement on age related cognitive decline - a systematic review.

2017-07-21

Knowledge on factors affecting the rate of cognitive decline and how to maintain cognitive functioning in old age becomes increasingly relevant. The purpose of the current study was to systematically review the evidence for the impact of retirement on cognitive functioning and on age related cognitive decline. We conducted a systematic literature review, following the principles of the PRISMA statement, of longitudinal studies on the association between retirement and cognition. Only seven studies fulfilled the inclusion criteria. We found weak evidence that retirement accelerates the rate of cognitive decline in crystallised abilities, but only for individuals retiring from jobs high in complexity with people. The evidence of the impact of retirement on the rate of decline in fluid cognitive abilities is conflicting. The review revealed a major knowledge gap in regards to the impact of retirement on cognitive decline. More knowledge on the association between retirement and age related cognitive decline as well as knowledge on the mechanisms behind these associations is needed.

Bridging the research-practice gap: breaking new ground in health care.

PubMed

Mulhall, A

2001-08-01

Many theorists have discussed the existence of a gap between nursing research and practice. Consequently much time and effort has been expended in trying to devise strategies to bridge this divide. This article explores what the research-practice gap is and discusses five important reasons for it. The issue is then raised as to whether or not there is a gap between evidence and practice, despite the existence of the gap between research and practice. This is explored in relation to the potential conflict between the 'know how' knowledge important in practice and the 'know that' knowledge important in academia. Finally, the concept of practitioner-centred research is described as one strategy that would effectively obliterate the research-practice gap as it is currently conceived.

There is an important knowledge gap in food allergy management in understanding the factors that determine allergic reactions to food, in gathering objective reports of reactions in real time, and in accessing patients' reaction-histories during consultations. We investigate how eHealth methods can close this knowledge gap. We report experiences with an online tool for reporting allergic reactions that we have developed as a web application. This application has been successfully validated by participants from Ireland and the UK, and is currently being used in a pilot where participants report allergic reactions in near-real time.

Clathrin-independent internalization and recycling

Abstract The functionality of receptor and channel proteins depends directly upon their expression level on the plasma membrane. Therefore, the ability to selectively adjust the surface level of a particular receptor or channel protein is pivotal to many cellular signalling events. The internalization and recycling pathway plays a major role in the regulation of protein surface level, and thus has been a focus of research for many years. Although several endocytic pathways have been identified, most of our knowledge has come from the clathrin-dependent pathway, while the other pathways remain much less well defined. Considering that clathrin-independent internalization may account for as much as 50% of the total endocytic activity in the cell, the lack of such knowledge constitutes a major gap in our efforts to understand how different internalization pathways are utilized and co-ordinated. Recent studies have provided valuable insights into this area, yet many more questions still remain. In this review, we will give a panoramic introduction to the current knowledge of various internalization and recycling pathways, with an emphasis on the latest findings that have broadened our view of the clathrin-independent pathways. We will also dedicate one section to the emerging studies of the clathrin-independent internalization pathways in neuronal cells. PMID:18039352

Device-tissue interactions: a collaborative communications system.

PubMed

Chekan, Edward; Whelan, Richard L; Feng, Alexander H

2013-07-29

Medical devices, including surgical staplers, energy-based devices, and access enabling devices, are used routinely today in the majority of surgical procedures. Although these technically advanced devices have proved to be of immense benefit to both surgeons and patients, their rapid development and continuous improvement have had the unintended consequence of creating a knowledge gap for surgeons due to a lack of adequate training and educational programs. Thus, there is an unmet need in the surgical community to collect existing data on device-tissue interactions and subsequently develop research and educational programs to fill this gap in surgical training. Gathering data and developing these new programs will require collaboration between doctors, engineers, and scientists, from both clinical practice and industry. This paper presents a communications system to enable this unique collaboration that can potentially result in significantly improved patient care.

Prevention of cardiovascular diseases.

Hobbs, F D Richard

2015-10-12

Cardiovascular disease (CVD) is the most important cause of premature death and disability globally. Much is known of the main aetiological risk factors, including elevated blood pressure, dyslipidaemia and smoking, with a raft of additional risks of increasing prevalence, such as obesity and diabetes. Furthermore, some of the most secure evidence-based management strategies in healthcare relate to interventions that modify risk. Yet major gaps remain in the implementation of such evidence, summarized in international guideline recommendations. Some of this gap relates to knowledge deficits amongst clinicians, but also to continued uncertainties over interpretation of the evidence base and areas where data are less available. This article collection in BMC Medicine seeks to offer reflections in each of these areas of uncertainty, spanning issues of better diagnosis, areas of controversy and glimpses of potentially potent future interventions in the prevention of CVD.

Challenges in Timeseries Analysis from Microlensing

NASA Astrophysics Data System (ADS)

Street, R. A.

2017-06-01

Despite a flood of discoveries over the last ~ 20 years, our knowledge of the exoplanet population is incomplete owing to a gap between the sensitivities of different detection techniques. However, a census of exoplanets at all separations from their host stars is essential to fully understand planet formation mechanisms. Microlensing offers an effective way to bridge the gap around 1-10 AU and is therefore one of the major science goals of the Wide Field Infrared Survey Telescope (WFIRST) mission. WFIRST's survey of the Galactic Bulge is expected to discover ~ 20,000 microlensing events, including ~ 3000 planets, which represents a substantial data analysis challenge with the modeling software currently available. This paper highlights areas where further work is needed. The community is encouraged to join new software development efforts aimed at making the modeling of microlensing events both more accessible and rigorous.

There is a gap between what the general public and its elected leaders know about climate change and what climate scientists understand about this critical issue. One such effort by the authors to fill this gap is the Climate Science Rapid Response Team (CSRRT), formed in November 2010 to provide rapid, high-quality climate science information to international news media and lawmakers. Currently, CSRRT has enlisted 250 top climate scientists, including those with expertise on the economics and policy matters, whom are committed to be on call for climate-related inquiries. CSRRT has responded to more than 300 inquiries including, from among many others, The White House, Congress, and local governmental officials, major television and cable news networks, radio programs, mainstream international newspaper outlets, and a broad range of online news providers. CSRRT scientists have also been provided extensive communication training to help encourage the use of jargon-free language so that clear communication with the broader public can be more successful. In addition to the CSRRT, the authors have undertaken several behind the scenes initiatives to increase public awareness about climate change. This presentation will describe the operation of CSRRT along with some of its highlights, as well as offer a peek into the authors' less public efforts that have had a major impact on various climate-related news stories and policy.

Diabetes emerges out to be a major epidemic in recent years that engulfs both developed and developing countries across the globe. India, a country witnessing rapid socioeconomic progress and urbanization carries a considerable share of the global diabetes burden. There has been an incongruity between disease burden and the technical capacity to make use of existing knowledge or to generate new knowledge to combat diabetes in India. This paper examines the role of different actors, organizations & institutions in shaping diabetology research in India using arrays of scientific indicators such as research output (publications and patents), research finance and role of policy-making bodies. This paper also identifies research gaps and challenges pertinent to this sector. A combination of three methods patent data analysis, publication data analysis and primary survey corroborated with secondary data to obtain desire objectives. We made an in-depth study of the patent and publication data (2000-2016) to know the research output and direction of Indian actors, institutions and organizations in the area of diabetes research. This paper identifies some key structural barriers and institutional challenges pertinent to diabetology research in India that will help in canvassing and formulating science, technology and policy guidelines for diabetology research in India CONCLUSION: Multilevel intervention requires bridging the gap between knowledge and action hence policy-making should align to balance resources with innovation capabilities.

Identify epilepsy-associated factors and calculate measures of impact, stigma, quality of life (QOL), knowledge-attitude-practice (KAP) and treatment gap in Prey Veng, Cambodia. This first Cambodian population-based case-control study had 96 epileptologist-confirmed epilepsy cases and 192 randomly selected matched healthy controls. Standard questionnaires, which have been used in similar settings, were used for collecting data on various parameters. Univariate and multivariate regression was done to determine odds ratios. Jacoby stigma, 31-item QOL, KAP etc were determined and so were the factors associated with them using STATA software. Treatment gap was measured using direct method. Multivariate analyses yielded family history of epilepsy, difficult or long delivery, other problems beside seizures (mainly mental retardation, hyperthermia), and eventful pregnancy of the subject's mother as factors associated with epilepsy. There was high frequency of seizure precipitants esp. those related to sleep. Population attributable risk (%) was: family history (15.0), eventful pregnancy of subject's mother (14.5), long/difficult birth (6.5), and other problem beside seizures (20.0). Mean stigma (1.9±1.1, on a scale of 3) was mainly related to treatment efficacy. Mean QOL (5.0±1.4 on a scale of 10) was mainly related to treatment regularity. Cause or risk factor could be determined in 56% of cases. Treatment gap was 65.8%. Factors in pre- and perinatal period were found to be most crucial for epilepsy risk in Cambodia which inturn provides major prevention opportunities. A global action plan for treatment, stigma reduction and improvement of QOL should be set-up in this country.

Advances, gaps, and future prospects in biological soil crust research

NASA Astrophysics Data System (ADS)

Weber, Bettina; Büdel, Burkhard; Belnap, Jayne

2017-04-01

Research progress has led to the understanding that biological soil crusts (biocrusts) are often complete miniature ecosystems comprising a variety of photosynthesizers (cyanobacteria, algae, lichens, bryophytes), decomposers like bacteria, fungi, and archaea, and heterotrophic organisms, like protozoa, nematodes, and microarthropods feeding on them. Biocrusts are one of the oldest terrestrial ecosystems, playing central roles in the structure and functioning of dryland ecosystems and presumably also influencing global biogeochemical cycles. On the other hand, biocrusts have been shown to be highly sensitive to global change, being easily destroyed by mechanical disturbance and severely threatened by minor changes in climate patterns. Despite the large increase in biocrust research, we still see major knowledge gaps which need to be tackled. Considering biodiversity studies, there are major regions of potential biocrust occurrence, where hardly any studies have been conducted. Molecular identification techniques are increasingly employed, but genetically characterized entities need to be linked with morphologically identified organisms to identify their ecological roles. Although there is a large body of research on the role of biocrusts in water and nutrient budgets, we are still far from closing the overall cycles. Results suggest that not all mechanisms have been identified, yet, leading to sometimes contradictory results between different studies. Knowledge on how to minimize impact to biocrusts during surface-disturbing activities has hardly been gained, and despite research efforts, instructions on effective biocrust restoration are still exemplary. In order to fill these research gaps, novel scientific approaches are needed. We expect that global research networks could be extremely helpful to answer scientific questions by tackling them within different regions, utilizing the same methodological techniques. Global networks could also be used for long-term monitoring approaches and to conduct meta-analyses on already existing scientific data. Finally, the experimental results obtained during multiple local studies need to be integrated and extrapolated to ecosystem and global scales in order to identify the overall role of biocrusts in the Earth system through time.

Pakistan is one of the two countries where polio remains endemic. Among multiple reasons of polio prevalence, false religious beliefs are accounted as major barriers towards polio immunization in Pakistan. Within this context, religious scholars are now engaged in polio immunization campaigns to dismantle the myths and battle the resurgence of polio in Pakistan. The objective of this study was to assess knowledge, attitudes and perceived barriers of Muslim scholars towards polio immunization in Pakistan. A descriptive, cross-sectional survey of Muslim scholars was conducted in Quetta and Peshawar divisions of Pakistan. From October to December 2015, a convenience sample of 770 Muslim scholars was recruited from the local mosques and religious institutions to participate in this study. Knowledge, attitudes, and perceived barriers were assessed by using self-administered, anonymous and pretested questionnaire. Descriptive and regression analyses were used to express the results with p < 0.05 taken as significant. Three hundred and forty-eight (45.2 %) participants exhibited good knowledge about polio with a mean score of 7.16 ± 2.12 (based on 14 questions). Knowledge gaps were identified about the transmission (32.6 %) and consequences of poliovirus (39.9 %). Overall, 527 (68.4 %) participants showed positive attitudes towards polio immunization with a mean attitude score of 27.35 ± 2.68 (based on nine statements). The majority of participants agreed on the need of depoliticizing polio immunization issues (87.1 %), while reservations were noted about their willingness to participate in future polio immunization programs (44.6 %). Security (75.8 %) and vaccine management issues (64 %) were reported by the participants as the major barriers towards polio immunization in Pakistan. The findings showed poor knowledge of Muslim scholars towards polio; however, their attitudes were positive towards polio immunization. More studies are required to assess the knowledge and attitudes of Muslim scholars at the national level to validate the findings of this study.

Mind the gap—deficits in our knowledge of aspects impacting the bioavailability of phytochemicals and their metabolites—a position paper focusing on carotenoids and polyphenols

Various secondary plant metabolites or phytochemicals, including polyphenols and carotenoids, have been associated with a variety of health benefits, such as reduced incidence of type 2 diabetes, cardiovascular diseases, and several types of cancer, most likely due to their involvement in ameliorating inflammation and oxidative stress. However, discrepancies exist between their putative effects when comparing observational and intervention studies, especially when using pure compounds. These discrepancies may in part be explained by differences in intake levels and their bioavailability. Prior to exerting their bioactivity, these compounds must be made bioavailable, and considerable differences may arise due to their matrix release, changes during digestion, uptake, metabolism, and biodistribution, even before considering dose‐ and host‐related factors. Though many insights have been gained on factors affecting secondary plant metabolite bioavailability, many gaps still exist in our knowledge. In this position paper, we highlight several major gaps in our understanding of phytochemical bioavailability, including effects of food processing, changes during digestion, involvement of cellular transporters in influx/efflux through the gastrointestinal epithelium, changes during colonic fermentation, and their phase I and phase II metabolism following absorption.

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

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

A challenging, and largely uncharted, area of research in the field of anaerobic digestion science and technology is in understanding the roles of trace metals in enabling biogas production. This is a major knowledge gap and a multifaceted problem involving metal chemistry; physical interactions of metal and solids; microbiology; and technology optimization. Moreover, the fate of trace metals, and the chemical speciation and transport of trace metals in environments--often agricultural lands receiving discharge waters from anaerobic digestion processes--simultaneously represents challenges for environmental protection and opportunities to close process loops in anaerobic digestion.

A resuscitation "dilemma" theory-practice-ethics. Is there a theory-practice-ethics gap?

PubMed

Mortell, Manfred

2009-07-01

The theory-practice-ethics gap - a new paradigm to contemplate. Practices based on tradition, rituals and outdated information are placed into a nonscientific paradigm called the theory-practice gap. Within this paradigm there is often a gap between theoretical knowledge and its application in practice. This theory-practice gap has always existed [Allmark, P., 1995. A classical view of the theory-practice gap in nursing. J. Adv. Nurs. 22 (1), 18-23; Hewison, A. et al., 1996. The theory-practice gap in nursing: a new dimension. J. Adv. Nurs. 24 (4), 754-761]. Its creation is often sited as a culmination of theory being idealistic and impractical, even if practical and beneficial, are often ignored. Most of the evidence relating to the non integration of theory and practice makes the assumption that environmental factors are responsible and will affect learning and practice outcomes, hence the "gap". In fact, it is the author's belief, that to "bridge the gap" between theory and practice an additional component is required, called ethics. A moral duty and obligation ensuring theory and practice integrate. In order to effectively implement new practices, one must deem these practices are worthy and relevant to their role as healthcare providers. Otherwise, we fall victims to providing nothing more than a lip service. This introduces a new concept which the author refers to as the theory-practice-ethics gap. This theory-practice-ethics gap must be considered when reviewing some of the unacceptable outcomes in health care practice. The author believes that there is a crisis of ethics where theory and practice integrate, and as a consequence, malfeasance. We are failing to fulfill our duty as healthcare providers and as patient advocates. One practice of major concern, which the author will endeavor to unfold relates to adult and pediatric resuscitation.

A review of citizen science and community-based environmental monitoring: issues and opportunities.

Conrad, Cathy C; Hilchey, Krista G

2011-05-01

Worldwide, decision-makers and nongovernment organizations are increasing their use of citizen volunteers to enhance their ability to monitor and manage natural resources, track species at risk, and conserve protected areas. We reviewed the last 10 years of relevant citizen science literature for areas of consensus, divergence, and knowledge gaps. Different community-based monitoring (CBM) activities and governance structures were examined and contrasted. Literature was examined for evidence of common benefits, challenges, and recommendations for successful citizen science. Two major gaps were identified: (1) a need to compare and contrast the success (and the situations that induce success) of CBM programs which present sound evidence of citizen scientists influencing positive environmental changes in the local ecosystems they monitor and (2) more case studies showing use of CBM data by decision-makers or the barriers to linkages and how these might be overcome. If new research focuses on these gaps, and on the differences of opinions that exist, we will have a much better understanding of the social, economic, and ecological benefits of citizen science.

To examine the nutrition and young child feeding (YCF) education and training of nurses in public health clinics of Ghana's Komenda-Edina-Eguafo-Abrem region (KEEA) in relation to global health guidelines, and how nurses served as educators for caregivers with children aged 0-5 years. A qualitative study of semi-structured one-on-one and group interviews (n 21) following a questionnaire of closed- and open-ended questions addressing child feeding, nutrition and global health recommendations. Interviews were conducted in English, audio-recorded, transcribed and coded. Descriptive data were tabulated. Content analysis identified themes from open-ended questions. KEEA public health clinics (n 12). Nurses (n 41) purposefully recruited from KEEA clinics. A model capturing nurses' nutrition and YCF education emerged with five major themes: (i) adequacy of nurses' basic knowledge in breast-feeding, complementary feeding, iron-deficiency anaemia, YCF and hygiene; (ii) nurses' delivery of nutrition and YCF information; (iii) nurses' evaluation of children's health status to measure education effectiveness; (iv) nurses' perceived barriers of caregivers' ability to implement nutrition and YCF education; and (v) a gap in global health recommendations on YCF practices for children aged 2-5 years. Nurses demonstrated adequate nutrition and YCF knowledge, but reported a lack of in-depth nutrition knowledge and YCF education for children 2-5 years of age, specifically education and knowledge of YCF beyond complementary feeding. To optimize child health outcomes, a greater depth of nutrition and YCF education is needed in international health guidelines.

Rates of food allergies in children as well as the rate of families who employ nannies have increased dramatically over the past decade. It is essential that nannies have the knowledge and tools necessary to recognize and treat food allergy reactions. To identify gaps in knowledge in the nanny population with regard to food allergy in children. A Web-based survey was sent by e-mail to 709 nannies. A total of 153 nannies (22%) completed the online survey: 26% of respondents had formal educational training at a nanny school; 99% recognized food allergy as a potentially fatal event; 37% reported caring for a child with food allergies. Of these, 71% had food allergy action plans, and 63% had epinephrine available. A total of 71% reported training on administering epinephrine. The nannies' major concerns included accidental ingestion and discomfort in administering epinephrine. A total of 36% were uncomfortable with recognizing a food allergy emergency, whereas 46% were uncomfortable administering epinephrine; 6% thought that a sensitized child could safely eat a small amount of allergenic food, whereas 14% believed that dilution with water might reduce an allergic reaction. A total of 66% desired additional information about recognizing food allergies, and 71% agreed that food allergy training should be required for all nannies. Nannies demonstrated gaps in knowledge with regard to food allergy in children, which reflects the need for more stringent training and education. Increased communication among parents, nannies, and physicians is needed to protect children with food allergy. Copyright © 2014 American Academy of Allergy, Asthma & Immunology.

2016-09-01

Organ transplantation is the optimal treatment for end-stage organ diseases. The demand for organs has exceeded the available supply, which becomes a major obstacle worldwide. Identifying the factors affecting this gap will help in overcoming this obstacle. The purpose of the work was to study the knowledge, attitudes, and beliefs of organ donation and to determine the knowledge of brain death among social media users. A cross-sectional study was conducted among social media users living in Saudi Arabia. A pre-designed self-administrated questionnaire was distributed online randomly on social media networks in 2015. Of the total 1368 participants, only 913 met the criteria. Most respondents were between 18 and 29 years of age (61.2%) and living in the central region of Saudi Arabia (64.5%). The majority of respondents received their information from television (57%) and social media (50%) networks; 46.4% of respondents knew that the religious fatwa allowed organ donation; 51% of respondents were willing to donate their organs; 46.5% considered the brain-dead to be deceased, whereas 37.7% considered it a coma; 33.3% did not know if someone who was brain-dead would ever wake up; on the other hand, 323 (35.4%) said yes. Our study showed that the vast majority of our sample had enough information about organ donation. On the contrary, they had minimal knowledge about brain death. Moreover, a fair percentage of the participants had positive attitudes toward organ donation. Also, the media had a significant effect on the information about organ donation and brain death.

Locating relevant patient information in electronic health record data using representations of clinical concepts and database structures.

PubMed

Pan, Xuequn; Cimino, James J

2014-01-01

Clinicians and clinical researchers often seek information in electronic health records (EHRs) that are relevant to some concept of interest, such as a disease or finding. The heterogeneous nature of EHRs can complicate retrieval, risking incomplete results. We frame this problem as the presence of two gaps: 1) a gap between clinical concepts and their representations in EHR data and 2) a gap between data representations and their locations within EHR data structures. We bridge these gaps with a knowledge structure that comprises relationships among clinical concepts (including concepts of interest and concepts that may be instantiated in EHR data) and relationships between clinical concepts and the database structures. We make use of available knowledge resources to develop a reproducible, scalable process for creating a knowledge base that can support automated query expansion from a clinical concept to all relevant EHR data.

The purpose of this review is to report how administrative data have been used to study AKI, identify current limitations, and suggest how these data sources might be enhanced to address knowledge gaps in the field. 1) To review the existing evidence-base on how AKI is coded across administrative datasets, 2) To identify limitations, gaps in knowledge, and major barriers to scientific progress in AKI related to coding in administrative data, 3) To discuss how administrative data for AKI might be enhanced to enable "communication" and "translation" within and across administrative jurisdictions, and 4) To suggest how administrative databases might be configured to inform 'registry-based' pragmatic studies. Literature review of English language articles through PubMed search for relevant AKI literature focusing on the validation of AKI in administrative data or used administrative data to describe the epidemiology of AKI. Acute Dialysis Quality Initiative (ADQI) Consensus Conference September 6-7(th), 2015, Banff, Canada. Hospitalized patients with AKI. The coding structure for AKI in many administrative datasets limits understanding of true disease burden (especially less severe AKI), its temporal trends, and clinical phenotyping. Important opportunities exist to improve the quality and coding of AKI data to better address critical knowledge gaps in AKI and improve care. A modified Delphi consensus building process consisting of review of the literature and summary statements were developed through a series of alternating breakout and plenary sessions. Administrative codes for AKI are limited by poor sensitivity, lack of standardization to classify severity, and poor contextual phenotyping. These limitations are further hampered by reduced awareness of AKI among providers and the subjective nature of reporting. While an idealized definition of AKI may be difficult to implement, improving standardization of reporting by using laboratory-based definitions and providing complementary information on the context in which AKI occurs are possible. Administrative databases may also help enhance the conduct of and inform clinical or registry-based pragmatic studies. Data sources largely restricted to North American and Europe. Administrative data are rapidly growing and evolving, and represent an unprecedented opportunity to address knowledge gaps in AKI. Progress will require continued efforts to improve awareness of the impact of AKI on public health, engage key stakeholders, and develop tangible strategies to reconfigure infrastructure to improve the reporting and phenotyping of AKI. WHY IS THIS REVIEW IMPORTANT?: Rapid growth in the size and availability of administrative data has enhanced the clinical study of acute kidney injury (AKI). However, significant limitations exist in coding that hinder our ability to better understand its epidemiology and address knowledge gaps. The following consensus-based review discusses how administrative data have been used to study AKI, identify current limitations, and suggest how these data sources might be enhanced to improve the future study of this disease. WHAT ARE THE KEY MESSAGES?: The current coding structure of administrative data is hindered by a lack of sensitivity, standardization to properly classify severity, and limited clinical phenotyping. These limitations combined with reduced awareness of AKI and the subjective nature of reporting limit understanding of disease burden across settings and time periods. As administrative data become more sophisticated and complex, important opportunities to employ more objective criteria to diagnose and stage AKI as well as improve contextual phenotyping exist that can help address knowledge gaps and improve care.

2014-01-01

Public libraries have been called the “first responders” to the specialized health information needs of the general public. The challenges inherent in consumer health information (CHI) service are centered around the Patron, the Librarian, the Information Resources, and the Library itself. The pilot study involved interviews with nine individual library workers in eight public libraries in four library systems: the District of Columbia, Montgomery and Prince George’s Counties in Maryland, and Fairfax County in Virginia. Library workers were asked about common consumer health information requests, the nature of their collections, and the role of public libraries in meeting these information needs. The subjects were also presented with a hypothetical scenario, and their responses suggest knowledge gaps. The findings point to the increasing necessity and importance of training and support for public librarians, as well as the importance of understanding where the medical knowledge gaps exist. Public librarians need to commit to formal evaluation of their skill sets and knowledge gaps, in order to identify areas to which libraries can devote limited resources. PMID:26550002

The aim of this study was to assess the physicians' attitude, their knowledge and their experience in pharmacogenomic clinical decision support in German hospitals. We conducted an online survey to address physicians of 13 different medical specialties across eight German university hospitals. In total, 564 returned questionnaires were analyzed. The remaining knowledge gap, the uncertainty of test reimbursement and the physicians' lack of awareness of existing pharmacogenomic clinical decision support systems (CDSS) are the major barriers for implementing pharmacogenomic CDSS into German hospitals. Furthermore, pharmacogenomic CDSS are most effective in the form of real-time decision support for internists. Physicians in German hospitals require additional education of both genetics and pharmacogenomics. They need to be provided with access to relevant pharmacogenomic CDSS.

Despite efforts to limit underage access to alcohol, alcohol availability remains a challenge for youth drinking prevention. This paper fills a gap in our understanding of alcohol consumption among youths by systematically investigating how and under what circumstances they obtain alcohol and the context within which they consume it. Qualitative interviews (n=47) were conducted with teens to collect information about where and how they obtain alcohol and the contexts within which they drink. Respondents were knowledgeable about commercial and social sources and used this knowledge in their decision making regarding where to obtain alcohol. Teens used their social relationships to circumvent existing policies designed to limit underage access to alcohol. Findings indicate that the majority of teens’ drinking occasions occur in their own or someone else’s home. PMID:25445811

2010-12-01

The field of knowledge utilization has been hampered by several issues including: the synonymous use of multiple terms with little attempt at definition precision; an overexamination of knowledge utilization as product, rather than a process; and a lack of progress to cross disciplinary boundaries to advance knowledge development. In order to address the challenges and current knowledge gaps in the knowledge utilization field in nursing, a comprehensive picture of the current state of the field is required. Bibliometric analyses were used to map knowledge utilization literature in nursing as an international field of study, and to identify the structure of its scientific community. Analyses of bibliographic data for 433 articles from the period 1945-2004 demonstrated three trends: (1) there has been significant recent growth and interest in this field, (2) the structure of the scientific knowledge utilization community is evolving, and (3) the Web of Science does not index the majority of journals where this literature is published. In order to enhance the accessibility and profile of this literature, and nursing's scientific literature at large, we encourage the International Academy of Nursing Editors to work collaboratively to increase the number of journals indexed in the Web of Science. ©2010 Sigma Theta Tau International.

Provision of travel medicine advice through community pharmacies: assessment of knowledge, attitudes and practices of pharmacists in Malaysia.

2016-10-01

The risk for travel-related illnesses has increased with significant growth in international travel, but very few travellers seek travel advice. Community pharmacists can play a vital role in the provision of travel medicine advice due to their accessibility. This study aimed to assess travel medicine knowledge, attitudes and practices (KAP) among community pharmacists in Kuala Lumpur, Malaysia. A self-administered KAP questionnaire was distributed to a convenience sample of pharmacists in Kuala Lumpur identified from the list of licensed community pharmacists in Malaysia year 2014. Questionnaires were returned by 111 pharmacists of 143 distributed (response rate, 78%). Most of the respondents (82%) were not trained in travel medicine. Overall, mean knowledge score was 4.4 ( ± 1.7), indicating a moderate level of knowledge on a variety of travel-related health issues. Community pharmacists who graduated from foreign universities possessed significantly higher knowledge scores than did those who graduated locally (P < 0.05). The majority had a positive attitude towards travel medicine. A vast majority provided travel medicine advice mainly to adults who travel as tourists, and the primary travel advice given was on traveller's diarrhoea. There are gaps in the knowledge and practice of travel medicine among Malaysian pharmacists. Positive attitudes of pharmacists towards travel medicine and appropriate interventions, such as incorporation of travel medicine in local pharmacy curricula, continuous pharmacy education or certified training may improve the quality of travel advice given and allow pharmacists to be recognised as a credible source of information on travel medicine. © 2016 Royal Pharmaceutical Society.

Recent research in developmental psychology shows that children understand several principles of fairness by 3 years of age, much earlier than previously believed. However, children's knowledge of fairness does not always align with their behavior, and immediate self-interest alone cannot explain this gap. In this forum paper, we consider two factors that influence the relation between fairness knowledge and behavior: relative advantage and how rewards are acquired. Copyright © 2014 Elsevier Ltd.

The gap in educational attainment separating underrepresented minorities from Whites and Asians remains wide. Such a gap has significant impact on workforce diversity and inclusion among cross-cutting Biomedical Data Science (BDS) research, which presents great opportunities as well as major challenges for addressing health disparities. This article provides a brief description of the newly established National Institutes of Health Big Data to Knowledge (BD2K) diversity initiatives at four universities: California State University, Monterey Bay; Fisk University; University of Puerto Rico, Río Piedras Campus; and California State University, Fullerton. We emphasize three main barriers to BDS careers (ie, preparation, exposure, and access to resources) experienced among those pioneer programs and recommendations for possible solutions (ie, early and proactive mentoring, enriched research experience, and data science curriculum development). The diversity disparities in BDS demonstrate the need for educators, researchers, and funding agencies to support evidence-based practices that will lead to the diversification of the BDS workforce PMID:28439180

2016-01-01

As the majority of prescribing in hospital is undertaken by intern doctors, the aims of this systematic review were to compile the evidence of the qualitative literature on the views and experiences of intern doctors and to examine the role of the pharmacist in assisting in prescribing by interns. A systematic review of the qualitative literature was done according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement. The findings were synthesized using thematic analysis. Seven publications were included. Factors influencing prescribing behaviour were related to the environment; collaboration in medical teams; hierarchical structures; and patient and individual factors. This review confirmed that interns’ prescribing behaviour is influenced by multiple factors, and further highlighted the need for an educational intervention that supports the intern completing the prescribing task in a complex environment, and not just addresses the presumed knowledge gap(s).

The incidence and prevalence of most cardiovascular disorders increase with age, and cardiovascular disease is the leading cause of death and major disability in adults ≥75 years of age; however, despite the large impact of cardiovascular disease on quality of life, morbidity, and mortality in older adults, patients aged ≥75 years have been markedly underrepresented in most major cardiovascular trials, and virtually all trials have excluded older patients with complex comorbidities, significant physical or cognitive disabilities, frailty, or residence in a nursing home or assisted living facility. As a result, current guidelines are unable to provide evidence-based recommendations for diagnosis and treatment of older patients typical of those encountered in routine clinical practice. The objectives of this scientific statement are to summarize current guideline recommendations as they apply to older adults, identify critical gaps in knowledge that preclude informed evidence-based decision making, and recommend future research to close existing knowledge gaps. To achieve these objectives, we conducted a detailed review of current American College of Cardiology/American Heart Association and American Stroke Association guidelines to identify content and recommendations that explicitly targeted older patients. We found that there is a pervasive lack of evidence to guide clinical decision making in older patients with cardiovascular disease, as well as a paucity of data on the impact of diagnostic and therapeutic interventions on key outcomes that are particularly important to older patients, such as quality of life, physical function, and maintenance of independence. Accordingly, there is a critical need for a multitude of large population-based studies and clinical trials that include a broad spectrum of older patients representative of those seen in clinical practice and that incorporate relevant outcomes important to older patients in the study design. The results of these studies will provide the foundation for future evidence-based guidelines applicable to older patients, thereby enhancing patient-centered evidence-based care of older people with cardiovascular disease in the United States and around the world.

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

PubMed

Carter, Tim

2011-01-01

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

Background Although numerous leadership development programs exist in healthcare, no programs have been specifically designed to meet the needs of surgeons. This study aimed to elicit practicing surgeons’ motivations and desired goals for leadership training in order to design an evidence-based Leadership Development Program (LDP) in surgery. Materials and Methods At a large academic health center, we conducted semi-structured interviews with 24 surgical faculty members who voluntarily applied and were selected for participation in a newly created LDP. Transcriptions of the interviews were analyzed using analyst triangulation and thematic coding in order to extract major themes regarding surgeons’ motivations and perceived needs for leadership knowledge and skills. Themes from interview responses were then used to design the program curriculum specifically to meet the leadership needs of surgical faculty. Results Three major themes emerged regarding surgeons’ motivations for seeking leadership training: 1) Recognizing key gaps in their formal preparation for leadership roles; 2) Exhibiting an appetite for personal self-improvement; and 3) Seeking leadership guidance for career advancement. Participants’ interviews revealed four specific domains of knowledge and skills that they indicated as desired takeaways from a leadership development program: 1) leadership and communication; 2) team building; 3) business acumen/finance; and 4) greater understanding of the healthcare context. Conclusions Interviews with surgical faculty members identified gaps in prior leadership training and demonstrated concrete motivations and specific goals for participating in a formal leadership program. A Leadership Development Program that is specifically tailored to address the needs of surgical faculty may benefit surgeons at a personal and institutional level. PMID:26323368

To identify gaps in residents' confidence and knowledge in managing chronic nonmalignant pain (CNMP) and to explore whether specific skills or pain knowledge was associated with global preparedness to manage CNMP. Cross-sectional web-based survey. Internal medicine residents in Bronx, NY. The authors assessed the following: 1) confidence in skills within the following four content areas: physical examination, diagnosis, treatment, and safer opioid prescribing; 2) pain-related knowledge on a 16-item scale; and 3) global preparedness to manage CNMP (agreement with, "I feel prepared to manage CNMP"). Gaps in confidence were skills in which fewer than 50 percent reported confidence. Gaps in knowledge were items in which fewer than 50 percent answered correctly. Using logistic regression, the authors examined whether skills or knowledge was associated with global preparedness. Of 145 residents, 92 (63 percent) responded. Gaps in confidence included diagnosing fibromyalgia, performing corticosteroid injections, and using pain medication agreements. Gaps in knowledge included pharmacotherapy for neuropathic pain and interpreting urine drug test results. Twenty-four residents (26 percent) felt globally prepared to manage CNMP. Confidence using pain medication agreements (adjusted odds ratio [AOR], 5.99; 95% confidence interval [CI], 2.02-17.75), prescribing long-acting opioids (AOR, 5.85; 95% CI, 2.00-17.18), and performing corticosteroid injection of the knee (AOR, 5.76; 95% CI, 1.16-28.60]) were strongly associated with global preparedness. Few internal medicine residents felt prepared to manage CNMP. Our findings suggest that educational interventions to improve residents' preparedness to manage CNMP should target complex pain syndromes (eg, fibromyalgia and neuropathic pain), safer opioid prescribing practices, and alternatives to opioid analgesics.

Objective To identify gaps in residents’ confidence and knowledge in managing chronic non-malignant pain (CNMP) and to explore whether specific skills or pain knowledge were associated with global preparedness to manage CNMP. Design Cross-sectional web-based survey Setting & Participants Internal medicine residents in Bronx, NY Main Outcome Measures We assessed: (1) confidence in skills within four content areas: physical examination, diagnosis, treatment, and safer opioid prescribing; (2) pain-related knowledge on a 16-item scale; and (3) global preparedness to manage CNMP (agreement with, “I feel prepared to manage CNMP”). Gaps in confidence were skills in which fewer than 50% reported confidence. Gaps in knowledge were items in which fewer than 50% answered correctly. Using logistic regression, we examined whether skills or knowledge were associated with global preparedness. Results Of 145 residents, 92 (63%) responded. Gaps in confidence included diagnosing fibromyalgia, performing corticosteroid injections, and using pain medication agreements. Gaps in knowledge included pharmacotherapy for neuropathic pain and interpreting urine drug test results. Twenty-four residents (26%) felt globally prepared to manage CNMP. Confidence using pain medication agreements (AOR 5.99, 95% CI: 2.02, 17.75), prescribing long-acting opioids (AOR 5.85, 95%CI: 2.00, 17.18), and performing corticosteroid injection of the knee (AOR 5.76, 95% CI: 1.16, 28.60]) were strongly associated with global preparedness. Conclusions Few internal medicine residents felt prepared to manage CNMP. Our findings suggest that educational interventions to improve residents’ preparedness to manage CNMP should target complex pain syndromes (e.g., fibromyalgia and neuropathic pain), safer opioid prescribing practices, and alternatives to opioid analgesics.

In the U.S., foodborne disease causes millions of illnesses annually, resulting in thousands of deaths. To reduce food poisoning, restaurant food handlers need accurate knowledge of food safety principles as a starting point for the outcome of optimal food safety behavior. The study described in this article determined food safety knowledge gaps among suburban Chicago restaurant food handlers. A cross-sectional survey of 729 food handlers at 211 suburban Chicago restaurants was conducted from June 2009 through February 2010. A 50-question survey was administered by a trained interviewer in either English or Spanish. Mixed-effects regression analysis identified risk factors associated with an overall food safety knowledge score. The mean overall knowledge score was only 72% and substantial knowledge gaps related to cross contamination, cooking, and holding and storage of food were identified. Spanish-speaking food handlers scored significantly lower than English-speaking food handlers (p < .05). Although certified food managers scored significantly higher than noncertified food handlers, their score was only 79%. These data provide targets for educational interventions to remedy knowledge gaps in food handlers in order to prevent food poisoning from restaurants.

The World Mental Health Surveys conducted by the World Health Organization (WHO) have shown that huge treatment gaps for severe mental disorders exist in both developed and developing countries. This gap is greatest in low and middle income countries (LMICs). Efforts to scale up mental health services in LMICs have to contend with the paucity of mental health professionals and health facilities providing specialist services for mental, neurological and substance use (MNS) disorders. A pragmatic solution is to improve access to care through the facilities that exist closest to the community, via a task-shifting strategy. This study describes a pilot implementation program to integrate mental health services into primary health care in Nigeria. The program was implemented over 18 months in 8 selected local government areas (LGAs) in Osun state of Nigeria, using the WHO Mental Health Gap Action Programme Intervention Guide (mhGAP-IG), which had been contextualized for the local setting. A well supervised cascade training model was utilized, with Master Trainers providing training for the Facilitators, who in turn conducted several rounds of training for front-line primary health care workers. The first set of trainings by the Facilitators was supervised and mentored by the Master Trainers and refresher trainings were provided after 9 months. A total of 198 primary care workers, from 68 primary care clinics, drawn from 8 LGAs with a combined population of 966,714 were trained in the detection and management of four MNS conditions: moderate to severe major depression, psychosis, epilepsy, and alcohol use disorders, using the mhGAP-IG. Following training, there was a marked improvement in the knowledge and skills of the health workers and there was also a significant increase in the numbers of persons identified and treated for MNS disorders, and in the number of referrals. Even though substantial retention of gained knowledge was observed nine months after the initial training, some level of decay had occurred supporting the need for a refresher training. It is feasible to scale up mental health services in primary care settings in Nigeria, using the mhGAP-IG and a well-supervised cascade-training model. This format of training is pragmatic, cost-effective and holds promise, especially in settings where there are few specialists.

Performance of Extra-Vehicular Activities (EVA) has been and will continue to be a critical capability for human space flight. Human exploration missions beyond LEO will require EVA capability for either contingency or nominal activities to support mission objectives and reduce mission risk. EVA systems encompass a wide array of products across pressure suits, life support systems, EVA tools and unique spacecraft interface hardware (i.e. EVA Translation Paths and EVA Worksites). In a fiscally limited environment with evolving transportation and habitation options, it is paramount that the EVA community's strategic planning and architecture integration products be reviewed and vetted for traceability between the mission needs far into the future to the known technology and knowledge gaps to the current investments across EVA systems. To ascertain EVA technology and knowledge gaps many things need to be brought together, assessed and analyzed. This includes an understanding of the destination environments, various mission concept of operations, current state of the art of EVA systems, EVA operational lessons learned, and reference advanced capabilities. A combined assessment of these inputs should result in well-defined list of gaps. This list can then be prioritized depending on the mission need dates and time scale of the technology or knowledge gap closure plan. This paper will summarize the current state of EVA related technology and knowledge gaps derived from NASA's Exploration EVA Reference Architecture and Operations Concept products. By linking these products and articulating NASA's approach to strategic development for EVA across all credible destinations an EVA could be done in, the identification of these gaps is then used to illustrate the tactical and strategic planning for the EVA technology development portfolio. Finally, this paper illustrates the various "touch points" with other human exploration risk identification areas including human health and performance.

Human Research Program Human Health Countermeasures Element Bone and Muscle Risk Standing Review Panel (SRP)

NASA Technical Reports Server (NTRS)

Glowacki, Julie; Gregor, Robert

2009-01-01

The Bone and Muscle Risk Standing Review Panel (SRP) met at the NASA Johnson Space Center (JSC) on October 4-6, 2009 to discuss the areas of current and future research targeted by the Human Health Countermeasures (HHC) Element of the Human Research Program (HRP). Using evidence-based knowledge as a background for identified risks to astronaut health and performance, NASA had identified gaps in knowledge to address those risks. Ongoing and proposed tasks were presented to address the gaps. The charge to the Bone and Muscle Risk SRP was to review the gaps, evaluate whether the tasks addressed these gaps and to make recommendations to NASA s HRP Science Management Office regarding the Panel's review. The Bone and Muscle Risk SRP consisted of scientists who are experts in muscle, bone, or both and could evaluate the existing evidence with sufficient knowledge of the potential effects of long duration exposure to microgravity. More important, although expertise in basic science is important, the SRP was requested to evaluate the practicality of the proposed efforts in light of the realistic demands placed on the HRP. In short, all tasks presented in the Integrated Research Plan (IRP) should address specific questions related to the challenges faced by the astronauts as a result of prolonged exposure to microgravity. All tasks proposed to fill the gaps in knowledge should provide applied, translational data necessary to answer the specific questions. Several presentations were made to the SRP during the site visit and the SRP spent sufficient time to address the panel charge, either as a group or in separate sessions for the Bone and Muscle Risk subgroups. The SRP made a final debriefing to the HRP Program Scientist, Dr. John B. Charles, on October 6, 2009. Taking the evidence and identified risks as givens, the SRP concluded that 1) integration of information should lead to a more comprehensive approach to identifying the gaps, 2) not all tasks addressed the gaps as stated in the IRP, 3) better access should be given to the SRP to existing data to include in its review, and 4) there were some missing gaps and tasks. As a result the SRP recommended 1) combining certain gaps, which in some cases were addressed with identical tasks, 2) additional gaps and tasks to address some of the gaps, 3) deleting some gaps and tasks to better focus the efforts of NASA s HRP in prioritizing their efforts, and 4) prioritizing gaps to address significant issues needing resolution in the short term while maintaining an awareness of long-term goals. The SRP commended the efforts by the HHC Element to integrate knowledge gaps and design tasks to address the higher order questions. This integration did not apply to the Bone and Muscle Risk alone, but the musculoskeletal system as its functions integrate with issues in

The Role of Internet Engagement in the Health-knowledge Gap

PubMed Central

Lee, Chul-joo

2014-01-01

The current research posits that education leads to differential levels of Internet engagement, which moderate the association between Internet use for health information and general health knowledge. Using a nationally representative survey that covers adults between the ages of 40 and 70 in the United States, it is found that education is positively related to Internet engagement. Also, Internet use has stronger associations with health knowledge for people exhibiting high Internet engagement than for people exhibiting low Internet engagement. The implications of these findings for research on both Internet use and knowledge gaps are discussed. PMID:25530667

Managing Uncertainty in Water Infrastructure Design Using Info-gap Robustness

NASA Astrophysics Data System (ADS)

Irias, X.; Cicala, D.

2013-12-01

Info-gap theory, a tool for managing deep uncertainty, can be of tremendous value for design of water systems in areas of high seismic risk. Maintaining reliable water service in those areas is subject to significant uncertainties including uncertainty of seismic loading, unknown seismic performance of infrastructure, uncertain costs of innovative seismic-resistant construction, unknown costs to repair seismic damage, unknown societal impacts from downtime, and more. Practically every major earthquake that strikes a population center reveals additional knowledge gaps. In situations of such deep uncertainty, info-gap can offer advantages over traditional approaches, whether deterministic approaches that use empirical safety factors to address the uncertainties involved, or probabilistic methods that attempt to characterize various stochastic properties and target a compromise between cost and reliability. The reason is that in situations of deep uncertainty, it may not be clear what safety factor would be reasonable, or even if any safety factor is sufficient to address the uncertainties, and we may lack data to characterize the situation probabilistically. Info-gap is a tool that recognizes up front that our best projection of the future may be wrong. Thus, rather than seeking a solution that is optimal for that projection, info-gap seeks a solution that works reasonably well for all plausible conditions. In other words, info-gap seeks solutions that are robust in the face of uncertainty. Info-gap has been used successfully across a wide range of disciplines including climate change science, project management, and structural design. EBMUD is currently using info-gap to help it gain insight into possible solutions for providing reliable water service to an island community within its service area. The island, containing about 75,000 customers, is particularly vulnerable to water supply disruption from earthquakes, since it has negligible water storage and is entirely dependent on four potentially fragile water transmission mains for its day-to-day water supply. Using info-gap analysis, EBMUD is evaluating competing strategies for providing water supply to the island, for example submarine pipelines versus tunnels. The analysis considers not only the likely or 'average' results for each strategy, but also the worst-case performance of each strategy under varying levels of uncertainty. This analysis is improving the quality of the planning process, since it can identify strategies that ensure minimal disruption of water supply following a major earthquake, even if the earthquake and resulting damage fail to conform to our expectations. Results to date are presented, including a discussion of how info-gap analysis complements existing tools for comparing alternative strategies, and how info-gap improves our ability to quantify our tolerance for uncertainty.

An Inquiry-Based Approach to Teaching Space Weather to Undergraduate Non-Science Majors

NASA Astrophysics Data System (ADS)

Cade, W. B., III

2016-12-01

Undergraduate Space Weather education is an important component of creating a society that is knowledgeable about space weather and its societal impacts. The space physics community has made great strides in providing academic education for students, typically physics and engineering majors, who are interested in pursuing a career in the space sciences or space weather. What is rarely addressed, however, is providing a broader space weather education to undergraduate students as a whole. To help address this gap, I have created an introductory space weather course for non-science majors, with the idea of expanding exposure to space weather beyond the typical physics and engineering students. The philosophy and methodologies used in this course will be presented, as well as the results of the first attempts to teach it. Using an approach more tailored to the non-scientist, courses such as this can be an effective means of broadening space weather education and outreach.

Knowledge translation is an interactive, dynamic approach to the uptake of evidence-based knowledge. In this article, the authors present a collaborative model for knowledge translation that grew out of a program of research focusing on the experiences of patients from ethnoculturally diverse groups as they were discharged home from hospital. Research findings highlight issues around gaps in the continuity of services and language and communication. The authors discuss a number of knowledge translation initiatives that were developed to address these gaps. Key to the success of this process has been a collaborative relationship between researchers and practitioners that is grounded in the shared goal of knowledge translation to support ethically sound decision-making in the delivery of health-care services.

Background Despite being entirely preventable, canine rabies still kills 55,000 people/year in developing countries. Information about local beliefs and practices can identify knowledge gaps that may affect prevention practices and lead to unnecessary deaths. Methodology/Principal Findings We investigated knowledge, attitudes and practices related to rabies and its prevention and control amongst a cross-section of households (n = 5,141) in urban and rural areas of central, southern and northern Tanzania. Over 17% of respondents owned domestic dogs (average of 2.3 dogs/household),>95% had heard about rabies, and>80% knew that rabies is transmitted through dog bites. People who (1) had greater education, (2) originated from areas with a history of rabies interventions, (3) had experienced exposure by a suspect rabid animal, (4) were male and (5) owned dogs were more likely to have greater knowledge about the disease. Around 80% of respondents would seek hospital treatment after a suspect bite, but only 5% were aware of the need for prompt wound cleansing after a bite. Although>65% of respondents knew of dog vaccination as a means to control rabies, only 51% vaccinated their dogs. Determinants of dog vaccination included (1) being a male-headed household, (2) presence of children, (3) low economic status, (4) residing in urban areas, (5) owning livestock, (6) originating from areas with rabies interventions and (7) having purchased a dog. The majority of dog-owning respondents were willing to contribute no more than US$0.31 towards veterinary services. Conclusions/Significance We identified important knowledge gaps related to, and factors influencing the prevention and control of rabies in Tanzania. Increasing knowledge regarding wound washing, seeking post-exposure prophylaxis and the need to vaccinate dogs are likely to result in more effective prevention of rabies; however, greater engagement of the veterinary and medical sectors is also needed to ensure the availability of preventative services.

This report proposes potential research priorities for the Department of Energy (DOE) with the intent of improving the licensability of the Sodium Fast Reactor (SFR). In support of this project, five panels were tasked with identifying potential safety-related gaps in available information, data, and models needed to support the licensing of a SFR. The areas examined were sodium technology, accident sequences and initiators, source term characterization, codes and methods, and fuels and materials. It is the intent of this report to utilize a structured and transparent process that incorporates feedback from all interested stakeholders to suggest future funding priorities formore » the SFR research and development. While numerous gaps were identified, two cross-cutting gaps related to knowledge preservation were agreed upon by all panels and should be addressed in the near future. The first gap is a need to re-evaluate the current procedures for removing the Applied Technology designation from old documents. The second cross-cutting gap is the need for a robust Knowledge Management and Preservation system in all SFR research areas. Closure of these and the other identified gaps will require both a reprioritization of funding within DOE as well as a re-evaluation of existing bureaucratic procedures within the DOE associated with Applied Technology and Knowledge Management.« less

2016-06-01

Rapid economic development in China has produced serious ecological, environmental, and health problems. Neurotoxicity has been recognized as a major public health problem. The Chinese government, research institutes, and scientists conducted extensive studies concerning the source, characteristics, and mechanisms of neurotoxicants. This paper presents, for the first time, a comprehensive history and review of major sources of neurotoxicants, national bodies/legislation engaged, and major neurotoxicology research in China. Peer-reviewed research and pollution studies by Chinese scientists from 1991 to 2015 were examined. PubMed, Web of Science and Chinese National Knowledge Infrastructure (CNKI) were the major search tools. The central problem is an increased exposure to neurotoxicants from air and water, food contamination, e-waste recycling, and manufacturing of household products. China formulated an institutional framework and standards system for management of major neurotoxicants. Basic and applied research was initiated, and international cooperation was achieved. The annual number of peer-reviewed neurotoxicology papers from Chinese authors increased almost 30-fold since 2001. Despite extensive efforts, neurotoxicity remains a significant public health problem. This provides great challenges and opportunities. We identified 10 significant areas that require major educational, environmental, governmental, and research efforts, as well as attention to public awareness. For example, there is a need to increase efforts to utilize new in vivo and in vitro models, determine the potential neurotoxicity and mechanisms involved in newly emerging pollutants, and examine the effects and mechanisms of mixtures. In the future, we anticipate working with scientists worldwide to accomplish these goals and eliminate, prevent and treat neurotoxicity. Cai T, Luo W, Ruan D, Wu YJ, Fox DA, Chen J. 2016.

Endoscopy training is a central component of gastroenterology training for the vast majority of UK trainees, and integral to this is the practice of safe sedation. The majority of endoscopic procedures are performed with the patient under conscious sedation with a benzodiazepine, often combined with an opioid. Little data exists on the practice of sedation among gastroenterology trainees, including their degree of knowledge of the common sedation agents used and their actions. Using both an online and paper-based questionnaire, we surveyed current gastroenterology speciality trainees (ST) in the UK and received 78 responses giving a response rate of 10%. Fifty-one per cent of the trainees did not receive structured training in safe sedation, despite national guidelines advising this to be an essential part of the training programme, and 92% felt a structured sedation course would be beneficial. We also identified some gaps in trainees’ knowledge of the action of sedation agents. We propose that a formal training session in sedation or an e-learning module could be incorporated as part of a deanery or trust induction for gastroenterology trainees and kept under regular review.

Life scientists increasingly use visual analytics to explore large data sets and generate hypotheses. Undergraduate biology majors should be learning these same methods. Yet visual analytics is one of the most underdeveloped areas of undergraduate biology education. This study sought to determine the feasibility of undergraduate biology majors conducting exploratory analysis using the same interactive data visualizations as practicing scientists. We examined 22 upper level undergraduates in a genomics course as they engaged in a case-based inquiry with an interactive heat map. We qualitatively and quantitatively analyzed students' visual analytic behaviors, reasoning and outcomes to identify student performance patterns, commonly shared efficiencies and task completion. We analyzed students' successes and difficulties in applying knowledge and skills relevant to the visual analytics case and related gaps in knowledge and skill to associated tool designs. Findings show that undergraduate engagement in visual analytics is feasible and could be further strengthened through tool usability improvements. We identify these improvements. We speculate, as well, on instructional considerations that our findings suggested may also enhance visual analytics in case-based modules.

This essay addresses the problem of the essentiality of nursing knowledge and what kind of theory, if any, is essential to nursing practice. The overarching aim of the essay was to argue for the thesis that nursing may be described as a kind of philosophical activity, and, consequently, that philosophy is the kind of "theory" that is essential to nursing practice and to the nursing discipline at large. The essay consists of two papers. The present paper, Part I, is a critical examination of Mark Risjord's discussion of the problem of the theory-practice gap in his Nursing Knowledge: Practice, Science, Philosophy, from 2010. According to Risjord, the cause of the theory-practice gap originates in an erroneous conception of science (logical positivism) which had a decisive influence upon the way nursing scholars appropriated theoretical frameworks for the nursing discipline. This philosophical influence is considered in effect to have generated the theory-practice gap. In order to bridge the gap, Risjord suggests, the nursing discipline needs to adopt a standpoint epistemology conjoined with a postpositivist conception of scientific theory. In this way, a legitimate brand of nursing science may be developed and the theory-practice gap overcome. I will argue that neither Risjord's diagnosis of the problem, nor his recommended cure, may succeed in rescuing the nursing discipline from the theory-practice gap. Rather, the real cause of the theory-practice gap, I will claim, derives from an erroneous conception of nursing (not of science), namely the conception of nursing as a kind of science (roughly speaking). On my view, to overcome the gap, the nursing discipline needs to make salient the inherently philosophical character of nursing. In the second paper (Part II), I will continue the discussion of nursing knowledge and delineate the thesis of nursing as a kind of concrete philosophy. © 2017 John Wiley & Sons Ltd.

Purpose: The "transgender tipping point" has brought transgender social and health issues to the forefront of American culture. However, medical professionals have been lagging in academic research with a transgender-specific focus resulting in significant knowledge gaps in dealing with the care of our transgender patients. The aim of this article is to analyze all published Medline-available transgender-specific articles, identify these knowledge gaps, and direct future research to where it is most needed. Methods: We surveyed all Medline-available articles up to June 2016 using a combination of medical subject headings and keywords in titles and abstracts. Articles meeting inclusion criteria were reviewed, categorized, and analyzed for content and study design. Results: In our review of the literature, we identified 2405 articles published from January 1950 to June 2016 that focused on transgender health, primarily in the fields of surgery, mental health, and endocrinology. Conclusion: Significant knowledge gaps were found across the subspecialties, and there was a lack of prospective robust research and representation of transgender-specific data in the core medical journals. More data and research are needed to bridge the knowledge gaps that currently exist and improve the care of the transgender community.

Cross-disciplinary research in cancer: an opportunity to narrow the knowledge-practice gap.

PubMed

Urquhart, R; Grunfeld, E; Jackson, L; Sargeant, J; Porter, G A

2013-12-01

Health services researchers have consistently identified a gap between what is identified as "best practice" and what actually happens in clinical care. Despite nearly two decades of a growing evidence-based practice movement, narrowing the knowledge-practice gap continues to be a slow, complex, and poorly understood process. Here, we contend that cross-disciplinary research is increasingly relevant and important to reducing that gap, particularly research that encompasses the notion of transdisciplinarity, wherein multiple academic disciplines and non-academic individuals and groups are integrated into the research process. The assimilation of diverse perspectives, research approaches, and types of knowledge is potentially effective in helping research teams tackle real-world patient care issues, create more practice-based evidence, and translate the results to clinical and community care settings. The goals of this paper are to present and discuss cross-disciplinary approaches to health research and to provide two examples of how engaging in such research may optimize the use of research in cancer care.

Collaboration and co-production of climate knowledge: lessons from a network on the front-line

NASA Astrophysics Data System (ADS)

Kettle, N.

2016-12-01

The science-practice gap is broadly considered a major barrier to the production and application of decision-relevant science. This study uses a social network analysis, based on 126 interviews, to analyze the roles and network ties among climate scientists, service providers, and decision makers in Alaska. Our research highlights the importance of key actors and significant differences in bonding and bridging ties across roles - structural characteristics that provide a basis for informing recommendations to build adaptive capacity and support the co-production of knowledge. Our findings also illustrate that some individuals in the network engage in multiple roles, suggesting that conceptualizing the science-practice interface as consisting of "producers" and "consumers" oversimplifies how individuals engage in climate science, services, and decision making. This research supports the notion that the development and use of climate information is a networked phenomenon. It also emphasizes the importance of centralized individuals who are capable of engaging in multiple roles for the transition of knowledge action.

An integrated science-based methodology to assess potential risks and implications of engineered nanomaterials.

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

Ammonia oxidation: Ecology, physiology, biochemistry and why they must all come together.

PubMed

Lehtovirta-Morley, Laura E

2018-05-01

Ammonia oxidation is a fundamental core process in the global biogeochemical nitrogen cycle. Oxidation of ammonia (NH3) to nitrite (NO2 -) is the first and rate-limiting step in nitrification and is carried out by distinct groups of microorganisms. Ammonia oxidation is essential for nutrient turnover in most terrestrial, aquatic and engineered ecosystems and plays a major role, both directly and indirectly, in greenhouse gas production and environmental damage. Although ammonia oxidation has been studied for over a century, this research field has been galvanised in the past decade by the surprising discoveries of novel ammonia oxidising microorganisms. This review reflects on the ammonia oxidation research to date and discusses the major gaps remaining in our knowledge of the biology of ammonia oxidation.

A majority of cancer diagnoses and deaths occur in patients age ≥ 65 years. With the aging of the US population, the number of older adults with cancer will grow. Although the coming wave of older patients with cancer was anticipated in the early 1980s, when the need for more research on the cancer-aging interface was recognized, many knowledge gaps remain when it comes to treating older and/or frailer patients with cancer. Relatively little is known about the best way to balance the risks and benefits of existing cancer therapies in older patients; however, these patients continue to be underrepresented in clinical trials. Furthermore, the available clinical trials often do not include end points pertinent to the older adult population, such as preservation of function, cognition, and independence. As part of its ongoing effort to advance research in the field of geriatric oncology, the Cancer and Aging Research Group held a conference in November 2012 in collaboration with the National Cancer Institute, the National Institute on Aging, and the Alliance for Clinical Trials in Oncology. The goal was to develop recommendations and establish research guidelines for the design and implementation of therapeutic clinical trials for older and/or frail adults. The conference sought to identify knowledge gaps in cancer clinical trials for older adults and propose clinical trial designs to fill these gaps. The ultimate goal of this conference series is to develop research that will lead to evidence-based care for older and/or frail adults with cancer. PMID:25071116

Exploring sex and gender differences in sleep health: a Society for Women's Health Research Report.

Previous attempts have been made to address sleep disorders in women; however, significant knowledge gaps in research and a lack of awareness among the research community continue to exist. There is a great need for scientists and clinicians to consider sex and gender differences in their sleep research to account for the unique biology of women. To understand the role of sex differences in sleep and the state of women's sleep health research, the Society for Women's Health Research convened an interdisciplinary expert panel of well-established sleep researchers and clinicians for a roundtable meeting. Focused discussions on basic and clinical research along with a focus on specific challenges facing women with sleep-related problems and effective therapies led to the identification of knowledge gaps and the development of research-related recommendations. Additionally, sex differences in sleep disorders were noted and discussed in the context of underlying hormonal differences. Differences in sleep behavior and sleep disorders may not only be driven by biological factors but also by gender differences in the way women and men report symptoms. Progress has been made in identifying sex and gender differences in many areas of sleep, but major research gaps in the areas of epidemiology, sleep regulation, sleep quality, diagnosis, and treatment need to be addressed. Identifying the underlying nature of sex and gender differences in sleep research has potential to accelerate improved care for both men and women facilitating better diagnosis, treatment, and ultimately prevention of sleep disorders and related comorbid conditions.

Contemporary emphasis on measuring and evaluating observable, behavioral outcomes reflects a major change in the profession toward greater empirical basis for social work practice. This intellectual and methodological shift has created a gap between practitioners and researchers. While social work practitioners definitely should be more knowledgeable and receptive to interventions that have proven to be effective in helping people, social work academics must pay more attention to the realities of social work practitioners who struggle daily with expanding caseloads, ever-increasing time pressures to help clients whose lives are embedded in poverty, unemployment, oppression, racism, homelessness, and violence.

Corynebacterium diphtheriae is a globally important Gram-positive aerobic Actinobacterium capable of causing the toxin-mediated disease, diphtheria. Diphtheria was a major cause of childhood mortality prior to the introduction of the toxoid vaccine, yet it is capable of rapid resurgence following the breakdown of healthcare provision, vaccination or displacement of people. The mechanism and treatment of toxin-mediated disease is well understood, however there are key gaps in our knowledge on the basic biology of C. diphtheriae particularly relating to host colonisation, the nature of asymptomatic carriage, population genomics and host adaptation.

Impact of Stone Removal on Renal Function: A Review

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

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

Occupational Therapists With Oncology Exposure: Perceived Needs on Adults and Older Adults With Cancer-Related Cognitive Impairments.

Ulfers, Sara S; Berg, Christine

2017-07-01

Cancer-related cognitive impairments (CRCI) can limit participation in meaningful activities before, during, and after cancer treatment. This study explored occupational therapists' perceived knowledge gaps and needs regarding CRCI in adults and older adults. An online survey was sent to a convenience sample of 60 practitioners at facilities throughout the continuum of care and 176 directors and faculty in accredited occupational therapy programs. Using a snowball sampling approach, recipients were asked to forward the survey to other occupational therapists. One hundred seven occupational therapists participated. The majority (92%) responded that it would be beneficial to attend a face-to-face continuing education program; preferences for the content and design of a continuing competency seminar are described. These findings support the development and delivery of continuing competence programs tailored toward occupational therapists' CRCI knowledge needs.

This review attempts to provide some sense of our current knowledge of water including overall patterns of intake and some factors linked with intake, the complex mechanisms behind water homeostasis, the effects of variation in water intake on health and energy intake, weight, and human performance and functioning. Water represents a critical nutrient whose absence will be lethal within days. Water’s importance for prevention of nutrition-related noncommunicable diseases has emerged more recently because of the shift toward large proportions of fluids coming from caloric beverages. Nevertheless, there are major gaps in knowledge related to measurement of total fluid intake, hydration status at the population level, and few longer-term systematic interventions and no published random-controlled longer-term trials. We suggest some ways to examine water requirements as a means to encouraging more dialogue on this important topic. PMID:20646222

NASA, like many other organizations, is facing major challenges when it comes to its workforce. The average age of its personnel is 46, and 68 percent of its population is between 35 and 55. According to the U.S. Government Accounting Office, if the workforce continues aging, not enough engineers will have moved up the ranks and have the requisite skills to enable NASA to meet its vision for space exploration. In order to meet its goals of developing a new generation of spacecraft to support human spaceflight to the moon and Mars, the agency must engage and retain younger generations of workers and bridge the gaps between the four generations working today. Knowledge sharing among the generations is more critical than ever. This paper describes the strategies used to develop the NASA Engineering Network with the goal of engaging different generations.

Child maltreatment is associated with a huge burden of suffering, yet there are serious gaps in knowledge about its epidemiology and approaches to intervention. This article describes the development of a proposed national research framework in child maltreatment, as requested by the Department of Justice, Canada, based on (1) a review of the literature, (2) consultation with experts, and (3) application of evaluation criteria for considering research priorities. The article identifies gaps in knowledge about child maltreatment in Canada and proposes a research agenda to make evidence-based policy decisions more likely. Although this work was driven by gaps in Canada's knowledge about child maltreatment, the international scope of the review and consultation process could make the findings useful to broader research and policy audiences.

Closing the clinical gap: translating best practice knowledge to performance with guidelines implementation.

PubMed

Ishii, Lisa E

2013-06-01

Unsustainable health care costs coupled with opportunity for improvement in health care outcomes in the United States are stimulating meaningful transformation in the way we deliver care. One approach in this transformation focuses on minimizing unnecessary variation in physician practices, instead focusing on evidence-based medicine in a more uniform manner. Clinical practice guidelines contain evidence-based recommendations, articulate goals of care, and can help to reduce unnecessary variation. While thousands of clinical practice guidelines are in existence, a clinical gap exists between knowledge and clinical performance. With thoughtful guidelines implementation strategies in place, organizations can begin to close the gap and translate best practice knowledge into care. Health systems that have done this effectively have seen improved clinical outcomes, improved patient satisfaction, and lower cost per patient.

Formal university-child welfare partnerships offer a unique opportunity to begin to fill the gaps in the child welfare knowledge base and link child welfare services to the realities of practice. With resources from a knowledge mobilization grant, a formal partnership was developed between the University of Toronto, clinicians, policy analysts, and researchers from child welfare agencies across Ontario. The key objectives of the grant included: (1) enhancing the capacity of service providers to access and analyze child welfare data to inform service and policy decisions; (2) integrating clinical expertise in service and policy decisions; and (3) developing a joint research agenda addressing high-priority knowledge gaps. This partnership was an opportunity to advance the evidence base with respect to service provision in Ontario and to create a culture of knowledge and evidence that would eventually support more complex research initiatives. Administrative data was analyzed for this partnership through the Ontario Child Abuse and Neglect Data System (OCANDS)-the first child welfare data system in Ontario to track child welfare-involved children and their families. Child welfare agencies identified recurrence as an important priority and agency-driven analyses were subsequently conducted on OCANDS generated recurrence Service Performance Indicators (SPI's). Using an urgent versus chronic investigative taxonomy for analyses, findings revealed that the majority of cases did not recur within 12 months and cases identified as chronic needs are more likely to return to the attention of child welfare authorities. One of the key outcomes of the partnership - helping agencies to understand their administrative data is described, as are considerations for next steps for future partnerships and research.

Escalating morbidity and mortality associated with hepatitis B virus (HBV) and hepatitis C virus (HCV) infections represent a major health burden in Australia, particularly among migrants from endemic areas who may present late. We evaluated the knowledge and educational needs of general practitioners (GPs) in the St George Division, Sydney which serves a large migrant population. The aims of the study were to identify gaps in knowledge about viral hepatitis that may affect management and referral patterns. GPs completed a survey comprised of 15 questions. They were also invited to comment on barriers to managing viral hepatitis in migrant patients. A 44% response rate was achieved from 280 eligible GPs. Forty-two per cent of GPs lacked confidence in interpreting HCV serology and 20% for HBV serology. Twenty-two per cent of GPs did not recognise HCC as a complication of HBV and 18% for HCV. Twenty per cent of GPs were unaware of treatment for HBV. Forty-seven per cent of GPs were uncertain whether pregnant women could receive HCV treatment. Twenty-three per cent and 21% of respondents believed that all HCV- or HBV-infected mothers, respectively, should not breast-feed. Eighty-nine per cent of GPs identified language difficulties as the main barrier to treatment among the migrant population. There were gaps in the knowledge of GPs particularly concerning natural history, diagnosis, treatment availability and management of pregnant or lactating women with viral hepatitis. Specific educational initiatives targeting these deficits are required as well as increased availability of language resources for managing patients from a non-English-speaking background. © 2011 The Authors.

Conceição, Luis E C; Aragão, Cláudia; Richard, Nadège; Engrola, Sofia; Gavaia, Paulo; Mira, Sara; Dias, Jorge

Major gaps in knowledge on fish larval nutritional requirements still remain. Small larval size, and difficulties in acceptance of inert microdiets, makes progress slow and cumbersome. This lack of knowledge in fish larval nutritional requirements is one of the causes of high mortalities and quality problems commonly observed in marine larviculture. In recent years, several novel methodologies have contributed to significant progress in fish larval nutrition. Others are emerging and are likely to bring further insight into larval nutritional physiology and requirements. This paper reviews a range of new tools and some examples of their present use, as well as potential future applications in the study of fish larvae nutrition. Tube-feeding and incorporation into Artemia of (14)C-amino acids and lipids allowed studying Artemia intake, digestion and absorption and utilisation of these nutrients. Diet selection by fish larvae has been studied with diets containing different natural stable isotope signatures or diets where different rare metal oxides were added. Mechanistic modelling has been used as a tool to integrate existing knowledge and reveal gaps, and also to better understand results obtained in tracer studies. Population genomics may assist in assessing genotype effects on nutritional requirements, by using progeny testing in fish reared in the same tanks, and also in identifying QTLs for larval stages. Functional genomics and proteomics enable the study of gene and protein expression under various dietary conditions, and thereby identify the metabolic pathways which are affected by a given nutrient. Promising results were obtained using the metabolic programming concept in early life to facilitate utilisation of certain nutrients at later stages. All together, these methodologies have made decisive contributions, and are expected to do even more in the near future, to build a knowledge basis for development of optimised diets and feeding regimes for different species of larval fish.

Firstly, this paper gave a brief review of the core issues of previous studies on spatial distribution of knowledge spillovers. That laid the theoretical foundation for further research. Secondly, this paper roughly described the diffusion process of solar patents in Bejing-Tianjin-Hebei and the Pearl River Delta regions by means of correlation analysis based on patent information of the application date and address of patentee. After that, this paper introduced the variables of spatial distance, knowledge absorptive capacity, knowledge gap and pollution control and built the empirical model of patent, and then collecting data to test them. The results showed that knowledge absorptive capacity was the most significant factor than the other three, followed by the knowledge gap. The influence of spatial distance on knowledge spillovers was limited and the most weak influence factor was pollution control.

To study how much people with epilepsy in Europe know and understand about their condition and how this might affect their lives. Clinical, demographic, psychosocial details and information assessing knowledge were collected by using self-completion questionnaires mailed to members of epilepsy support groups. Data were collected from 6,156 people with epilepsy from ten European countries. There were significant between-country differences in all variables considered. Overall levels of knowledge were acceptable when measured by the epilepsy knowledge questionnaire (EKQ, medical items). However, there were some gaps in knowledge, particularly in issues relating to medication and cause of epilepsy. This is the largest study of its kind to date. Results clearly highlighted that levels of knowledge differed significantly between countries. Overall, people with epilepsy are reasonably well informed about epilepsy, although some gaps in knowledge were evident.

Despite widespread endorsement for administrative training during residency, teaching and learning in this area remains intermittent and limited in most programmes. To inform the development of a Manager Train-the-Trainer program for faculty, the Royal College of Physicians and Surgeons of Canada undertook a survey of perceived Manager training needs among postgraduate trainees. A representative sample of Canadian specialty residents received a web-based questionnaire in 2009 assessing their perceived deficiencies in 13 Manager knowledge and 11 Manager skill domains, as determined by gap scores (GSs). GSs were defined as the difference between residents' perceived current and desired level of knowledge or skill in selected Manager domains. Residents' educational preferences for furthering their Manager knowledge and skills were also elicited. Among the 549 residents who were emailed the survey, 199 (36.2%) responded. Residents reported significant gaps in most knowledge and skills domains examined. Residents' preferred educational methods for learning Manager knowledge and skills included workshops, web-based formats and interactive small groups. The results of this national survey, highlighting significant perceived gaps in multiple Manager knowledge and skills domains, may inform the development of Manager curricula and faculty development activities to address deficiencies in training in this important area.

The goal of this study was to identify knowledge gaps in clinicians who evaluate and treat performing artists for illnesses and injuries that affect vocal function in college health settings. This pilot study utilized a web-based cross-sectional survey design incorporating common clinical scenarios to test knowledge of evaluation and management strategies in the vocal performing artist. A web-based survey was administered to a purposive sample of 28 clinicians to identify the approach utilized to evaluate and treat vocal performing artists in college health settings, and factors that might affect knowledge gaps and influence referral patterns to voice specialists. Twenty-eight clinicians were surveyed, with 36% of respondents incorrectly identifying appropriate vocal hygiene measures, 56% of respondents failing to identify symptoms of vocal fold hemorrhage, 84% failing to identify other indications for referral to a voice specialist, 96% of respondents acknowledging unfamiliarity with the Voice Handicap Index and the Singers Voice Handicap Index, and 68% acknowledging unfamiliarity with the Reflux Symptom Index. The data elucidated specific knowledge gaps in college health providers who are responsible for evaluating and treating common illnesses that affect vocal function, and triaging and referring students experiencing symptoms of potential vocal emergencies. Future work is needed to improve the standard of care for this population. Copyright © 2018 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

Ambiguity in knowledge transfer: The role of theory-practice gap.

2010-01-01

In spite of much literature written about the theory-practice gap in the international nursing journals, there is evidence that indicates this subject has not been probed comprehensively since nursing education was transferred to universities in Iran. In the recent years, the public and the government have criticized Iranian nurses because of poor quality of patient care. Although this subject has been lamented by some researchers, there is no comprehensive work on how this gap resulted. In the process of a larger study on "nursing knowledge translation to practice", of one PhD thesis, this process was explored. Using grounded theory analysis, indepth interviews were undertaken with a purposive sample of 29 nurses, with different levels of experience, from the school of nursing in Tehran University of Medical Sciences in 2006 from January to August. Data were analyzed using the constant comparative method. Three main themes emerging from this study included clinical behavior structure, paradoxical knowledge and practice, and divergent nursing organization. It seems that nursing education with some praxis and paradoxes in the realm of nursing knowledge and practice, along with divergent organizational structure have decreased nurses' ability in applying their professional knowledge and skills in order to bridge the gap between theory and practice. Moreover, in spite of increased academic input into nursing education, clinical behaviors of both education and practice settings was perceived as "traditional routine-based".

The medical community has called upon pediatricians to be knowledgeable about an individualized education program (IEP). We sought to: 1) evaluate pediatricians' knowledge and attitudes regarding special education; 2) examine the relationship between perceived responsibilities and practice patterns; and 3) identify barriers that impact pediatricians' ability to provide comprehensive care to children with educational difficulties. Surveys were mailed to a national sample of 1000 randomly selected general pediatricians and pediatric residents from October 2010 to February 2011. The response rate was 47%. Of the knowledge items, respondents answered an average of 59% correctly. The majority of respondents thought pediatricians should be responsible for identifying children who may benefit from special education services and assist families in obtaining services, but less than 50% thought they should assist in the development of an IEP. The majority of pediatricians inquired whether a child is having difficulty at school, but far fewer conducted screening tests or asked parents if they needed assistance obtaining services. Overall, the prevalence of considering a practice a pediatrician's responsibility is significantly higher than examples of such a practice pattern being reported. Financial reimbursement and insufficient training were among the most significant barriers affecting a pediatrician's ability to provide care to children with educational difficulties. In order to provide a comprehensive medical home, pediatricians must be informed about the special education process. This study demonstrates that there are gaps in pediatricians' knowledge and practice patterns regarding special education that must be addressed. Copyright © 2013 Academic Pediatric Association.

Ponte, Charles D; Johnson-Tribino, Jennifer

2005-01-01

This study's objective was to determine the attitudes/beliefs and knowledge of West Virginia's family physicians regarding evaluation and treatment of patients with pain. A 20-item instrument (10 attitudinal/behavioral and 10 knowledge items) was mailed to 537 members of the West Virginia Chapter of the American Academy of Family Physicians in October 2002. Five percent of the surveys were mailed to out-of-state members. No follow-up questionnaire was mailed. A total of 186 surveys (186/537, 34.6%) were returned. The typical respondent was a male ages 30-54 graduating in 1983 or later and having 15.5 years of practice experience. The majority of respondents were in a solo or group practice. There were no differences in response rates according to age, gender, years in practice, and practice setting. Chronic nonmalignant pain and assessing pain in the elderly are problematic for many physician providers. Perceived regulatory scrutiny does impact physician prescribing of opioids for patients in pain. Knowledge gaps were uncovered in the areas of fentanyl administration, the use of propoxyphene in the elderly, the management of opioid-induced constipation, laxative prescription, and the use of oxygen to manage opioid-induced respiratory depression. The majority of respondents felt that their formal medical training did not prepare them to effectively manage pain. This survey provides valuable insight into the attitudes/behaviors and knowledge about pain and its management by West Virginia family physicians. A national sample, using a revised instrument, is needed to more fully characterize and validate the findings from this statewide survey.

An innovative addition to team-based-learning pedagogy to enhance teaching and learning: Students' perceptions of team exams.

PubMed

Khansari, Parto S; Coyne, Leanne

The study investigates students' perceptions of the value of implementing a team exam to enhance learning prior to a summative assessment. Team exams are similar to midterm exams, except that answering questions is a team effort. Data was collected from second year pharmacy students at California Northstate University College of Pharmacy (CNUCOP) through a self-administered online survey. The survey questions included closed-ended questions to evaluate students' perception on preparedness for a summative assessment and to rank advantages and disadvantages of the team exams. Of the 40 students who completed the survey (38% response rate), 100% of participants agreed that having a team exam prior to a major exam made them feel more prepared for a major summative exam. Ninety-seven percent of students believed that the team exam helped them to identify gaps in their knowledge and 85% agreed that taking a team exam reinforced their knowledge by teaching other students. The survey results did not identify any major disadvantages to holding a team exam. Students perceived that taking a team exam prior to a midterm exam is an effective approach to review the course contents and identify areas of improvement. Copyright © 2017.

Understanding information and education gaps among people with type 1 diabetes: a qualitative investigation.

PubMed

Rankin, David; Heller, Simon; Lawton, Julia

2011-04-01

Many patients with type 1 diabetes struggle to self-manage this chronic disease, often because they have a poor knowledge and understanding of the condition. However, little attention has been paid to examining the reasons for this poor knowledge/understanding. To inform future educational interventions, we explored patients' accounts of the education and information they had received since diagnosis, and the reasons behind gaps in their diabetes knowledge. Semi-structured interviews were conducted with 30 type 1 diabetes patients enrolled on a structured education programme in the UK. Data were analysed using an inductive, thematic approach. Patients' accounts illustrated a number of knowledge deficits which were influenced by various lifecourse events. Reasons for deficits included: diagnosis at a young age and assumption of decision-making responsibility by parents; lack of engagement with information when feeling well; transitions in care; inconsistency in information provision; and, lack of awareness that knowledge was poor or incomplete. Patients' knowledge deficits can arise for different reasons, at different points in the lifecourse, and may change over time. The delivery of individualised education should take account of the origins of patients' knowledge gaps and be provided on a regular and on-going basis. Copyright © 2010 Elsevier Ireland Ltd.

2017-03-28

A recognised research-to-practice gap exists in the health research field of sports injury prevention and safety promotion. There is a need for improved insight into increasing the relevancy, accessibility and legitimacy of injury prevention and safety promotion research knowledge for sport settings. The role of key organisations as intermediaries in the process of health knowledge translation for sports settings remains under-explored, and this paper aims to determine, and describe, the processes of knowledge translation undertaken by a set of key organisations in developing and distributing injury prevention and safety promotion resources. The National Guidance for Australian Football Partnerships and Safety (NoGAPS) project provided the context for this study. Representatives from five key NoGAPS organisations participated in individual face-to-face interviews about organisational processes of knowledge translation. A qualitative descriptive methodology was used to analyse participants' descriptions of knowledge translation activities undertaken at their respective organisations. Several themes emerged around health knowledge translation processes and considerations, including (1) identifying a need for knowledge translation, (2) developing and disseminating resources, and (3) barriers and enablers to knowledge translation. This study provides insight into the processes that key organisations employ when developing and disseminating injury prevention and safety promotion resources within sport settings. The relevancy, accessibility and legitimacy of health research knowledge is foregrounded, with a view to increasing the influence of research on the development of health-related resources suitable for community sport settings.

An emerging dimension of 21(st) century integrative biology is knowledge translation in global health. The maternal mortality rate in Somalia is amongst the highest in the world. We set out to study the "know-do" gap in family planning measures in Somalia, with a view to inform future interventions for knowledge integration between theory and practice. We interviewed 360 Somali females of reproductive age and compared university-educated females to women with less or no education, using structured interviews, with a validated questionnaire. The mean age of marriage was 18 years, with 4.5 pregnancies per marriage. The mean for the desired family size was 9.3 and 10.5 children for the university-educated group and the less-educated group, respectively. Importantly, nearly 90% of the university-educated group knew about family planning, compared to 45.6% of the less-educated group. All of the less-educated group indicated that they would never use contraceptives, as compared to 43.5% of the university-educated group. Prevalence of contraceptive use among ever-married women was 4.3%. In the less-educated group, 80.6% indicated that they would not recommend contraceptives to other women as compared to 66.0% of the university-educated group. There is a huge gap between knowledge and practice regarding family planning in Somalia. The attendant reasons for this gap, such as level of education, expressed personal religious beliefs and others, are examined here. For primary health care to gain traction in Africa, we need to address the existing "know-do" gaps that are endemic and adversely impacting on global health. This is the first independent research study examining the knowledge gaps for family planning in Somalia in the last 20 years, with a view to understanding knowledge integration in a global world. The results shall guide policy makers, donors, and implementers to develop a sound family planning policy and program to improve maternal and child health in 21(st) century primary healthcare.

ExMC Technology Watch

2013-01-01

The Technology Watch (Tech Watch) project is a NASA project that is operated under the Human Research Programs (HRP) Exploration Medical Capability (ExMC) element, and focuses on ExMC technology gaps. The project coordinates the efforts of several NASA centers, including the Johnson Space Center (JSC), Glenn Research Center (GRC), Ames Research Center (ARC), and the Langley Research Center (LaRC). The objective of Tech Watch is to identify emerging, high-impact technologies that augment current NASA HRP technology development efforts. Identifying such technologies accelerates the development of medical care and research capabilities for the mitigation of potential health issues encountered during human space exploration missions. The aim of this process is to leverage technologies developed by academia, industry and other government agencies and to identify the effective utilization of NASA resources to maximize the HRP return on investment. The establishment of collaborations with these entities is beneficial to technology development, assessment and/or insertion and further NASAs goal to provide a safe and healthy environment for human exploration. In 2012, the Tech Watch project expanded the scope of activities to cultivate student projects targeted at specific ExMC gaps, generate gap reports for a majority of the ExMC gaps and maturate a gap report review process to optimize the technical and managerial aspects of ExMC gap status. Through numerous site visits and discussions with academia faculty, several student projects were initiated and/or completed this past year. A key element to these student projects was the ability of the project to align with a specific ExMC technology or knowledge gap. These projects were mentored and reviewed by Tech Watch leads at the various NASA centers. Another result of the past years efforts was the population of the ExMC wiki website that now contains more the three quarters of the ExMC gap reports. The remaining gap reports will be completed in FY13. Finally, the gap report review process for all ExMC gaps was initiated. This review process was instrumental in ensuring that each gap report was thoroughly reviewed for accuracy and relevant content prior to its public release. In the upcoming year, the gap report review process will be refined such that in addition to the gap report update, programmatic information related to gap closure will also be emphasized.

Intelligent control for modeling of real-time reservoir operation, part II: artificial neural network with operating rule curves

NASA Astrophysics Data System (ADS)

Chang, Ya-Ting; Chang, Li-Chiu; Chang, Fi-John

2005-04-01

To bridge the gap between academic research and actual operation, we propose an intelligent control system for reservoir operation. The methodology includes two major processes, the knowledge acquired and implemented, and the inference system. In this study, a genetic algorithm (GA) and a fuzzy rule base (FRB) are used to extract knowledge based on the historical inflow data with a design objective function and on the operating rule curves respectively. The adaptive network-based fuzzy inference system (ANFIS) is then used to implement the knowledge, to create the fuzzy inference system, and then to estimate the optimal reservoir operation. To investigate its applicability and practicability, the Shihmen reservoir, Taiwan, is used as a case study. For the purpose of comparison, a simulation of the currently used M-5 operating rule curve is also performed. The results demonstrate that (1) the GA is an efficient way to search the optimal input-output patterns, (2) the FRB can extract the knowledge from the operating rule curves, and (3) the ANFIS models built on different types of knowledge can produce much better performance than the traditional M-5 curves in real-time reservoir operation. Moreover, we show that the model can be more intelligent for reservoir operation if more information (or knowledge) is involved.

Effects of major-road vehicle speed and driver age and gender on left-turn gap acceptance.

Because the driver's gap-acceptance maneuver is a complex and risky driving behavior, it is a highly concerned topic for traffic safety and operation. Previous studies have mainly focused on the driver's gap acceptance decision itself but did not pay attention to the maneuver process and driving behaviors. Using a driving simulator experiment for left-turn gap acceptance at a stop-controlled intersection, this study evaluated the effects of major traffic speed and driver age and gender on gap acceptance behaviors. The experiment results illustrate relationships among drivers' left-turn gap decision, driver's acceleration rate, steering action, and the influence of the gap-acceptance maneuver on the vehicles in the major traffic stream. The experiment results identified an association between high crash risk and high traffic speed at stop-controlled intersections. The older drivers, especially older female drivers, displayed a conservative driving attitude as a compensation for reduced driving ability, but also showed to be the most vulnerable group for the relatively complex driving maneuvers.

Managing caries: the need to close the gap between the evidence base and current practice.

2015-11-13

Underpinned by a changing knowledge of the aetiology of caries and its sequelae, and assisted by established and advancing dental materials, there is growing evidence supporting less invasive management of dental caries based on the principles of minimal intervention dentistry. This narrative review assesses both the evidence and the adoption of less invasive caries management strategies and describes ways in which the gap between evidence and practice might be overcome. While there is increasing data supporting less invasive management of carious lesions, these are not standard in most dental practices worldwide. Usually, clinical studies focused on efficacy as outcome, and did not take into consideration the views and priorities of other stakeholders, such as primary care dentists, educators, patients and those financing services. Involving these stakeholders into study design and demonstrating the broader advantages of new management strategies might improve translation of research into practice. In theory, clinical dentists can rely on a growing evidence in cariology regarding less invasive management options. In practice, further factors seem to impede adoption of these strategies. Future research should address these factors by involving major stakeholders and investigating their prioritised outcomes to narrow or close the evidence gap.

Health literacy and knowledge in a cohort of Australian patients taking warfarin.

To 1) characterise older patients taking warfarin, 2) assess these patients' level of warfarin knowledge, and 3) describe their strengths and limitations in health literacy, and 4) explore relationships between participants' characteristics, warfarin knowledge and health literacy. A warfarin knowledge questionnaire and Health Literacy Questionnaire (HLQ) were administered to older patients (aged >65 years, N=34) taking warfarin in an Australian general practice setting. Key gaps in participant knowledge pertained to the consequences of an international normalized ratio (INR) being below the target INR range and safety issues such as when to seek medical attention. A limitation for participants with a lower level of health literacy was the ability to appraise health information. Patients who needed assistance in completing the HLQs had significantly lower warfarin knowledge scores (p=0.03). Overseas-born participants and those taking 5 or more long-term medications had lower HLQ scores for specific scales (p<0.05). In this study warfarin knowledge gaps and a limitation of health literacy amongst a small sample of older patients were identified. The findings suggest that education and resources may need to be tailored to the needs of older patients taking warfarin and their carers to address these knowledge gaps and limitations in health literacy. Patients who may need greater support include those that need assistance in completing the HLQ, are overseas-born, or are taking 5 or more long-term medications.

As in other disciplines, the burgeoning knowledge in ENT medicine long ago surpassed our ability to adequately absorb it and maintain a proper overview. This can give rise to actual or assumed knowledge gaps that can impede the progress of the discipline and evidence-based treatment of patients. Clinics and medical practices also hold to traditional doctrines that shape day-to-day medicine, without these schools being challenged based on evidence. Between February and June 2015, 160 ENT clinics, including 34 university hospitals, and 2,670 ENT practices took part in a two-arm online survey on existing or perceived evidentiary gaps in ENT medicine using a previously development questionnaire. The survey used for half the participants was open in form; the other half were given a closed survey with systematics of the field for orientation. The survey was augmented with additional data such as the number of publications and focus areas in the clinics and the age and type of practice of the established physicians. The return rate from the clinics was 39.7%; the return rate of the closed surveys was 29.3%. Of the physicians in medical practice, 14.6% responded to the closed and 18.6% to the open survey. There were no major differences between the two forms of survey. Otological and oncological issues comprised approximately 30% of the list of answers from clinics. Corresponding questions were formulated regarding the current diagnostic and therapeutic problems, such as with stage-related tumor treatment or implantable hearing aids. Diagnostic procedures, e.g., special new procedures in audiology and vestibulogy, dominated the surveys from the practices. However clinics and practices alike cited marginal areas of the discipline that are of daily relevance. The cited knowledge gaps then needed to be verified or refuted and clarified based on research of the literature as to whether the existing evidence actually reached healthcare providers in the form of guidelines, publications, conferences or continuing training for application in daily practice. Other steps would include prioritizing future research, evidence mapping, deciding on further systematic reviews, and targeted studies in conjunction with procuring third-party funding and in cooperation with patient associations. The knowledge thus gained should ultimately be transferred in improved form for application in daily clinical practice. Ten questions of key importance each needed to be formulated for the hospitals and practices. © Georg Thieme Verlag KG Stuttgart · New York.

Talk, trust and time: a longitudinal study evaluating knowledge translation and exchange processes for research on violence against women

PubMed Central

2011-01-01

Background Violence against women (VAW) is a major public health problem. Translation of VAW research to policy and practice is an area that remains understudied, but provides the opportunity to examine knowledge translation and exchange (KTE) processes in a complex, multi-stakeholder context. In a series of studies including two randomized trials, the McMaster University VAW Research Program studied one key research gap: evidence about the effectiveness of screening women for exposure to intimate partner violence. This project developed and evaluated KTE strategies to share research findings with policymakers, health and community service providers, and women's advocates. Methods A longitudinal cross-sectional design, applying concurrent mixed data collection methods (surveys, interviews, and focus groups), was used to evaluate the utility of specific KTE strategies, including a series of workshops and a day-long Family Violence Knowledge Exchange Forum, on research sharing, uptake, and use. Results Participants valued the opportunity to meet with researchers, provide feedback on key messages, and make personal connections with other stakeholders. A number of factors specific to the knowledge itself, stakeholders' contexts, and the nature of the knowledge gap being addressed influenced the uptake, sharing, and use of the research. The types of knowledge use changed across time, and were specifically related to both the types of decisions being made, and to stage of decision making; most reported use was conceptual or symbolic, with few examples of instrumental use. Participants did report actively sharing the research findings with their own networks. Further examination of these second-order knowledge-sharing processes is required, including development of appropriate methods and measures for its assessment. Some participants reported that they would not use the research evidence in their decision making when it contradicted professional experiences, while others used it to support apparently contradictory positions. The online wiki-based 'community of interest' requested by participants was not used. Conclusions Mobilizing knowledge in the area of VAW practice and policy is complex and resource-intensive, and must acknowledge and respect the values of identified knowledge users, while balancing the objectivity of the research and researchers. This paper provides important lessons learned about these processes, including attending to the potential unintended consequences of knowledge sharing. PMID:21896170

New horizons in the implementation and research of comprehensive geriatric assessment: knowing, doing and the 'know-do' gap.

PubMed

Gladman, John R F; Conroy, Simon Paul; Ranhoff, Anette Hylen; Gordon, Adam Lee

2016-03-01

In this paper, we outline the relationship between the need to put existing applied health research knowledge into practice (the 'know-do gap') and the need to improve the evidence base (the 'know gap') with respect to the healthcare process used for older people with frailty known as comprehensive geriatric assessment (CGA). We explore the reasons for the know-do gap and the principles of how these barriers to implementation might be overcome. We explore how these principles should affect the conduct of applied health research to close the know gap. We propose that impaired flow of knowledge is an important contributory factor in the failure to implement evidence-based practice in CGA; this could be addressed through specific knowledge mobilisation techniques. We describe that implementation failures are also produced by an inadequate evidence base that requires the co-production of research, addressing not only effectiveness but also the feasibility and acceptability of new services, the educational needs of practitioners, the organisational requirements of services, and the contribution made by policy. Only by tackling these issues in concert and appropriate proportion, will the know and know-do gaps for CGA be closed. © The Author 2016.

By any measure, our efforts to protect and restore the environment have failed to keep pace with environmental change, despite extraordinary scientific advances. Clearly there is a problem in knowledge transfer, which is often blamed on limited public awareness, misunderstanding or even apathy. Whether it's moving research to practice, informing policy, or educating the public on the environmental challenges of our time, our track record is poor. A major part of our failure lies in how scientists and practitioners understand (or misunderstand) and practice knowledge transfer. What actually drives knowledge acquisition and the motivation to gain knowledge, and what does this say about the methods used for knowledge transfer? Is the problem a supply issue (deficit of knowledge) or a demand issue (personal relevance)? The false assumptions that spin out of how we conceptualize knowledge acquisition lead to investment in knowledge transfer balanced heavily in "science communication" and "awareness raising" activities that tend to be unidirectional, top-down, and rarely linked to personal interests. Successful adaptation to environmental change requires a theoretical and practical understanding of coupled natural-human systems as well as advances in bridging knowledge systems and the science-society gap. To be effective, this means a "translational science" approach that promotes the capture and integration of scientific and local knowledge, addresses the influences of scale (biophysically, socially, institutionally), encourages mutual learning among all parties, and builds capacity as part of the process. The facilitation and translation of information and meanings among stakeholders can lead to the co-production of knowledge, more informed decision making, and in a very pragmatic way, more effective use of assessments and other products of scientific discovery. The purpose of this presentation is to shed light on what underlies the majority of investment in knowledge transfer, the false assumptions that result, and the ramifications for the methods employed the vast majority of the time by the scientific community. The case for public engagement and participatory approaches will be made, followed by a brief survey of the theories, methods and tools that make engagement possible and effective. Successful adaptation to environmental change requires a much stronger link between science and society. While science communication and awareness raising are necessary, they are much more effective when coupled with robust, formative, and participatory approaches to stakeholder engagement. This is necessary for successful land-based adaptation to environmental change.

Individuals with cerebral palsy (CP) experience a significant gap in care as they move from interdisciplinary pediatric programs to limited or non-existent care in the adult sector. A lack of knowledgeable adult care providers has repeatedly been identified as a challenge in transitioning those with CP from pediatric to adult care. The objective of this study was to determine the extent to which Physiatrists provide care to adults with CP and to identify barriers to their engagement with this population. A survey was distributed to Physiatrists across Canada. Results were analyzed descriptively using SPSS software. Most Physiatrists provide care to very few adults with CP (10 or less), but over 80% feel that Physiatry is the most appropriate specialty to provide disability-related care to adults with CP following their pediatric discharge. Among the most frequently identified barriers to caring for this population were lack of accessible resources (i.e. social work, funded therapy, equipment) and lack of referrals. Physiatrists are willing and appropriate partners in transitioning patients with CP to adult care. Barriers to Physiatrists' engagement with this population appear to be amenable to change. A lack of knowledgeable and interested adult practitioners has repeatedly been identified as a challenge in transition planning for young adults with cerebral palsy (the vast majority of whom survive into adulthood). Physiatrists are ideally suited to manage adults with cerebral palsy, yet in this survey-based study, a majority of Canadian Physiatrists report caring for less than five adults with cerebral palsy on a regular basis. Barriers to further physiatric involvement in this population were reported to include lack of accessible resources and lack of referrals.

Major gaps in our knowledge of pathogen genes and how these gene products interact with host gene products to cause disease represent a major obstacle to progress in vaccine and antiviral drug development for the herpesviruses. To begin to bridge these gaps, we conducted a dual analysis of Murine Cytomegalovirus (MCMV) and host cell transcriptomes during lytic infection. We analyzed the MCMV transcriptome during lytic infection using both classical cDNA cloning and sequencing of viral transcripts and next generation sequencing of transcripts (RNA-Seq). We also investigated the host transcriptome using RNA-Seq combined with differential gene expression analysis, biological pathway analysis, and gene ontology analysis. We identify numerous novel spliced and unspliced transcripts of MCMV. Unexpectedly, the most abundantly transcribed viral genes are of unknown function. We found that the most abundant viral transcript, recently identified as a noncoding RNA regulating cellular microRNAs, also codes for a novel protein. To our knowledge, this is the first viral transcript that functions both as a noncoding RNA and an mRNA. We also report that lytic infection elicits a profound cellular response in fibroblasts. Highly upregulated and induced host genes included those involved in inflammation and immunity, but also many unexpected transcription factors and host genes related to development and differentiation. Many top downregulated and repressed genes are associated with functions whose roles in infection are obscure, including host long intergenic noncoding RNAs, antisense RNAs or small nucleolar RNAs. Correspondingly, many differentially expressed genes cluster in biological pathways that may shed new light on cytomegalovirus pathogenesis. Together, these findings provide new insights into the molecular warfare at the virus-host interface and suggest new areas of research to advance the understanding and treatment of cytomegalovirus-associated diseases.

Training needs analysis for engineering technicians in Oman

NASA Astrophysics Data System (ADS)

Al-Mughairi, Abdulkarim Sultan

This thesis examines the transition from the Omani Colleges of Technology (CT) to employment of its engineering graduates. It arises out of concerns that the transition to the labour market for engineering graduate is problematical. The research was carried out to identify the knowledge, skills, and abilities (KSA) of engineering technicians required in the Omani market place. The aim is to provide local curriculum designers in the Colleges of Technology with sufficient information about the required KSA in order to create and enhance the engineering curriculum so that it has greater capacity to meet the needs of a variety of stakeholders and of employers in particular. This in turn has the potential to bridge the gap between what is presently taught and what the workplace demands. Personnel psychologists identify views concerning the skills that are required for different jobs. One of these is based on the assumption that quite different skills are required in different jobs (SCANS, 1990). This view generates approaches within job analysis: the worker-oriented and the task-oriented approaches. This research uses Position Analysis Questionnaire (PAQ), which is a worker-oriented job analysis instrument, to investigate the KSA required to perform some of the engineering technician jobs in Omani industries. In addition, semi-structured interviews were used to investigate the factors that either hinder or entirely prevent the new graduates from Colleges of Technology from being accepted in the workforce pool. The major research findings concern the dimensions of knowledge, skills, and abilities of six engineering technician job titles and the major factors that hinder or (prevent) the technical college graduates from being accepted in the market place in Oman. These findings would definitely help design better transition route and bridge the gap between the CT technicians engineering programmes and the workplace demands.

2011-11-03

General Internal Medicine (GIM) has recently been approved as a subspecialty by the Royal College of Physicians and Surgeons of Canada. As such, there is a need to define areas of knowledge that a General Internist must learn in those two years of training. There is limited literature as to what competencies are needed in a GIM practice. Draft competencies for GIM (4th and 5th year residents in internal medicine) training were developed over eight years with input from many stakeholders. Practicing General Internists were surveyed and asked their perspective as to the level of importance of each of these competencies for GIM training. They were also asked if training gaps exist in current training programs. The survey was offered widely online in both English and French to gain perspectives from as many different contexts as possible. 157 General Internists, in practice on average for 15 years, responded from all of Canada's provinces and territories. Practice profiles were diverse (large urban centers to rural centers). The majority of the competencies surveyed were perceived as important to attain at least proficiency in. Perioperative care, risk reduction, and the management of common, emergent, and complex internal medicine problems were identified as key areas to focus training programs on, with respondents perceiving these should be mastered to an expert level. Training gaps were identified, most frequently in that of the manager role (example managing practice). This is the first study we are aware of to attempt to isolate the opinions of practicing Canadian General Internists as to the major competencies that should be mastered as a General Internist. We suggest that "generalism" in the context of GIM, does not mean a bit of knowledge about everything but that defined objectives for training in this 'newest' of Royal College subspecialties can be identified. This includes mastery of core areas such as perioperative care, risk reduction, and management of common, emergent and multiple internal medicine problems. The training gaps identified need to be addressed to ensure that General Internists continue to provide excellence in health care delivery.

Conceptual Model-Based Systems Biology: Mapping Knowledge and Discovering Gaps in the mRNA Transcription Cycle

PubMed Central

Somekh, Judith; Choder, Mordechai; Dori, Dov

2012-01-01

We propose a Conceptual Model-based Systems Biology framework for qualitative modeling, executing, and eliciting knowledge gaps in molecular biology systems. The framework is an adaptation of Object-Process Methodology (OPM), a graphical and textual executable modeling language. OPM enables concurrent representation of the system's structure—the objects that comprise the system, and behavior—how processes transform objects over time. Applying a top-down approach of recursively zooming into processes, we model a case in point—the mRNA transcription cycle. Starting with this high level cell function, we model increasingly detailed processes along with participating objects. Our modeling approach is capable of modeling molecular processes such as complex formation, localization and trafficking, molecular binding, enzymatic stimulation, and environmental intervention. At the lowest level, similar to the Gene Ontology, all biological processes boil down to three basic molecular functions: catalysis, binding/dissociation, and transporting. During modeling and execution of the mRNA transcription model, we discovered knowledge gaps, which we present and classify into various types. We also show how model execution enhances a coherent model construction. Identification and pinpointing knowledge gaps is an important feature of the framework, as it suggests where research should focus and whether conjectures about uncertain mechanisms fit into the already verified model.

The effector and scaffolding proteins AF6 and MUPP1 interact with connexin36 and localize at gap junctions that form electrical synapses in rodent brain.

PubMed

Li, X; Lynn, B D; Nagy, J I

2012-01-01

Electrical synapses formed by neuronal gap junctions composed of connexin36 (Cx36) occur in most major structures in the mammalian central nervous system. These synapses link ensembles of neurons and influence their network properties. Little is known about the macromolecular constituents of neuronal gap junctions or how transmission through electrical synapses is regulated at the level of channel conductance or gap junction assembly/disassembly. Such knowledge is a prerequisite to understanding the roles of gap junctions in neuronal circuitry. Gap junctions share similarities with tight and adhesion junctions in that all three reside at close plasma membrane appositions, and therefore may associate with similar structural and regulatory proteins. Previously, we reported that the tight junction-associated protein zonula occludens-1 (ZO-1) interacts with Cx36 and is localized at gap junctions. Here, we demonstrate that two proteins known to be associated with tight and adherens junctions, namely AF6 and MUPP1, are components of neuronal gap junctions in rodent brain. By immunofluorescence, AF6 and MUPP1 were co-localized with Cx36 in many brain areas. Co-immunoprecipitation and pull-down approaches revealed an association of Cx36 with AF6 and MUPP1, which required the C-terminus PDZ domain interaction motif of Cx36 for interaction with the single PDZ domain of AF6 and with the 10th PDZ domain of MUPP1. As AF6 is a target of the cAMP/Epac/Rap1 signalling pathway and MUPP1 is a scaffolding protein that interacts with CaMKII, the present results suggest that AF6 may be a target for cAMP/Epac/Rap1 signalling at electrical synapses, and that MUPP1 may contribute to anchoring CaMKII at these synapses. © 2011 The Authors.

Tapir and Krill are declarative languages for specifying actions and agents, respectively, that can be executed in simulation. As such, they bridge the gap between strictly declarative knowledge bases and strictly executable code. Tapir and Krill components can be combined to produce models of activity which can answer questions about mechanisms and processes using conventional inference methods and simulation. Tapir was used in DARPA's Rapid Knowledge Formation (RKF) project to construct models of military tactics from the Army Field Manual FM3-90. These were then used to build Courses of Actions (COAs) which could be critiqued by declarative reasoning or via Monte Carlo simulation. Tapir and Krill can be read and written by non-knowledge engineers making it an excellent vehicle for Subject Matter Experts to build and critique knowledge bases.

The goal of patient-centered outcomes research (PCOR) is to help patients and those who care for them make informed decisions about healthcare. However, the clinical research enterprise has not involved patients, caregivers, and other non-providers routinely in the process of prioritizing, designing and conducting research in hematopoietic cell transplantation (HCT). To address this need, the National Marrow Donor Program (NMDP)/Be The Match® engaged patients, caregivers, researchers and other key stakeholders in a two-year project with the goal of setting a PCOR agenda for the HCT community. Through a collaborative process, we identified six major areas of interest: 1) Patient, Caregiver and Family Education and Support; 2) Emotional, Cognitive and Social Health; 3) Physical Health and Fatigue; 4) Sexual Health and Relationships; 5) Financial Burden; and 6) Models of Survivorship Care Delivery. We then organized into multi-stakeholder Working Groups to identify gaps in knowledge and make priority recommendations for critical research to fill those gaps. Gaps varied by Working Group, but all noted that a historical lack of consistency in measures utilized and patient populations made it difficult to compare outcomes across studies and urged investigators to incorporate uniform measures and homogenous patient groups in future research. Some groups advised that additional pre-emptory work is needed before conducting prospective interventional trials, whereas others felt ready to proceed with comparative clinical effectiveness research studies. This report presents the results of this major initiative, and makes recommendations by Working Group on priority questions for PCOR in HCT. PMID:29408289

Engineering biological systems toward a sustainable bioeconomy.

Lopes, Mateus Schreiner Garcez

2015-06-01

The nature of our major global risks calls for sustainable innovations to decouple economic growth from greenhouse gases emission. The development of sustainable technologies has been negatively impacted by several factors including sugar production costs, production scale, economic crises, hydraulic fracking development and the market inability to capture externality costs. However, advances in engineering of biological systems allow bridging the gap between exponential growth of knowledge about biology and the creation of sustainable value chains for a broad range of economic sectors. Additionally, industrial symbiosis of different biobased technologies can increase competitiveness and sustainability, leading to the development of eco-industrial parks. Reliable policies for carbon pricing and revenue reinvestments in disruptive technologies and in the deployment of eco-industrial parks could boost the welfare while addressing our major global risks toward the transition from a fossil to a biobased economy.

The objective of this study was to assess Canadian general surgeons' knowledge of bariatric surgery and perceived availability of resources to manage bariatric surgery patients. A self-administered questionnaire was developed using a focus group of general surgeons. The questionnaire was distributed at two large general surgery conferences in September and November 2012. The survey was also disseminated via membership association electronic newsletters in November and December 2012. One hundred sixty-seven questionnaires were completed (104 practicing surgeons, 63 general surgery trainees). Twenty respondents were bariatric surgeons. Among 84 non-bariatric surgeons, 68.3 % referred a patient in the last year for bariatric surgery, 79 % agreed that bariatric surgery resulted in sustained weight loss, and 81.7 % would consider referring a family member. Knowledge gaps were identified in estimates of mortality and morbidity associated with bariatric procedures. The majority of surgeons surveyed have encountered patients with complications from bariatric surgery in the last year. Over 50 % of surgeons who do not perform bariatric procedures reported not feeling confident to manage complications, 35.4 % reported having adequate resources and equipment to manage morbidly obese patients, and few are able to transfer patients to a bariatric center. Of the respondents, 73.3 % reported residency training provided inadequate exposure to bariatric surgery, and 85.3 % felt that additional continuing medical education resources would be useful. There appears to be support for bariatric surgery among Canadian general surgeons participating in this survey. Knowledge gaps identified indicate the need for more education and resources to support general surgeons managing bariatric surgical patients.

The importance of a sustainable health workforce is increasingly recognised. However, the building of a future health workforce that is responsive to diverse population needs and demographic and economic change remains insufficiently understood. There is a compelling argument to be made for a comprehensive research agenda to address the questions. With a focus on Europe and taking a health systems approach, we introduce an agenda linked to the 'Health Workforce Research' section of the European Public Health Association. Six major objectives for health workforce policy were identified: (1) to develop frameworks that align health systems/governance and health workforce policy/planning, (2) to explore the effects of changing skill mixes and competencies across sectors and occupational groups, (3) to map how education and health workforce governance can be better integrated, (4) to analyse the impact of health workforce mobility on health systems, (5) to optimise the use of international/EU, national and regional health workforce data and monitoring and (6) to build capacity for policy implementation. This article highlights critical knowledge gaps that currently hamper the opportunities of effectively responding to these challenges and advising policy-makers in different health systems. Closing these knowledge gaps is therefore an important step towards future health workforce governance and policy implementation. There is an urgent need for building health workforce research as an independent, interdisciplinary and multi-professional field. This requires dedicated research funding, new academic education programmes, comparative methodology and knowledge transfer and leadership that can help countries to build a people-centred health workforce.

It is known that in the educational system of republic the astronomy is not taught as a separate subject. Moreover, there are no telescopes in the vast majority of schools. "Goodricke John" NGO of amateur astronomers tries to fill this gap by organizing practical lessons of astronomy in secondary schools. NGO is equipped with high quality portable amateur telescopes and organizes periodic mass observations of planets, Moon, star clusters, nebulae in Yerevan and in regions. In addition, mass observations of rare astronomical phenomena are organized, such as the transit of Venus and Mercury across the disk of the Sun. Being the only NGO of amateur astronomers, it has a goal to contribute to publicizing astronomical knowledge and to ensure the availability of astronomical equipment, telescopes also to those segments of the society who have no opportunity to deal with them, in particular, persons with disabilities, prisoners, persons with disabilities, prisoners, soldiers, children from orphanages, school children and others.

In high- and low-performing districts of Bangladesh, the study explored the demand-side of maternal healthcare by looking at differences in perceived knowledge and care-seeking behaviours of women in relation to postpartum haemorrhage or eclampsia. Haemorrhage and eclampsia are two major causes of maternal mortality in Bangladesh. The study was conducted during July 2006-December 2007. Both postpartum bleeding and eclampsia were recognized by women of different age-groups as severe and life-threatening obstetric complications. However, a gap existed between perception and actual care-seeking behaviours which could contribute to the high rate of maternal deaths associated with these conditions. There were differences in care-seeking practices among women in the two different areas of Bangladesh, which may reflect sociocultural differences, disparities in economic and educational opportunities, and a discrimination in the availability of care.

A Study of the Antecedents and Consequences of Members' Helping Behaviors in Online Community

NASA Astrophysics Data System (ADS)

Chu, Kuo-Ming

Despite the growing popularity of online communities, there are a major gap between practitioners and academicians as to how to share information and knowledge among members of these groups. However, none of the previous studies have integrated these variables into a more comprehensive framework. Thus more validations are required the aim of this paper is to develop a theoretical model that enables us to examine the antecedents and consequences effects of members’ helping behavior in online communities. The moderating effects of the sense of community on the relationships between members’ helping behaviors on information sharing and knowledge contribution are also evaluated. A complete model is developed for empirical testing. Using Yahoo’s members as the samples of this study, the empirical results suggested that online communities members’ helping behavior represents a large pool of product know-how. They seem to be a promising source of innovation capabilities for new product development.

Dyslipidaemia is one of the main risk factors for cardiovascular disease, the leading cause of death in Malaysia. This study assessed the awareness, knowledge and practice of lipid management among primary care physicians undergoing postgraduate training in Malaysia. Cross sectional study. Postgraduate primary care trainees in Malaysia. 759 postgraduate primary care trainees were approached through email or hard copy, of whom 466 responded. A self-administered questionnaire was used to assess their awareness, knowledge and practice of dyslipidaemia management. The total cumulative score derived from the knowledge section was categorised into good or poor knowledge based on the median score, where a score of less than the median score was categorised as poor and a score equal to or more than the median score was categorised as good. We further examined the association between knowledge score and sociodemographic data. Associations were considered significant when p<0.05. The response rate achieved was 61.4%. The majority (98.1%) were aware of the national lipid guideline, and 95.6% reported that they used the lipid guideline in their practice. The median knowledge score was 7 out of 10; 70.2% of respondents scored 7 or more which was considered as good knowledge. Despite the majority (95.6%) reporting use of guidelines, there was wide variation in their clinical practice whereby some did not practise based on the guidelines. There was a positive significant association between awareness and the use of the guideline with knowledge score (p<0.001). However there was no significant association between knowledge score and sociodemographic data (p>0.05). The level of awareness and use of the lipid guideline among postgraduate primary care trainees was good. However, there were still gaps in their knowledge and practice which are not in accordance with standard guidelines. Published by the BMJ Publishing Group Limited.

Cohen, Elisia L; Head, Katharine J

2013-01-01

To examine differences in knowledge, attitudes, and related practices among adopters and nonadopters of the human papillomavirus (HPV) vaccine, the researchers conducted 83 in-depth interviews with 18- to 26-year-old women. The study identified knowledge-attitude-practice gaps in the context of the HPV vaccine to explain why diffusion of a preventive innovation (such as the HPV vaccine) requires targeted risk communication strategies in order to increase demand. Salient findings included similarities between vaccinated and unvaccinated women's lack of knowledge and uncertainties about HPV and cervical cancer. Vaccinated women who had no knowledge of HPV or no-risk/low-risk perceptions of HPV reported receiving vaccination, indicating HPV risk protection behavior could precede knowledge acquisition for vaccinated women. These vaccinated women identified an interpersonal network supportive of vaccination and reported supportive social influences. Among unvaccinated women, unsupportive vaccination attitudes included low perceived personal risk of HPV. In contrast, unvaccinated women often cited erroneous beliefs that HPV could be avoided by abstinence, monogamy, and knowledge of their partners' sexual history as reasons that the vaccine was not personally relevant. Unvaccinated women cited interpersonal influences that activated short- and long-term vaccination safety and efficacy concerns. Different levels of fear regarding the HPV vaccine may underlie (a) attitudinal differences between vaccinated and unvaccinated women in perceived vaccination value and (b) attitude-practice gaps.

Objective To assess any gaps between published best practices and real-world practices of treating depression in home health care (HHC), and barriers to closing any gaps. Methods A qualitative study based on semi-structured interviews with HHC nurses and administrators from five home health agencies in five states (n=20). Audio-recorded interviews were transcribed and analyzed by a multi-disciplinary team using grounded theory method to identify themes. Results Routine home health nursing care overlapped with all functional areas of depression care. However, there were reported gaps between best practices and real-world practices. Gaps were associated with perceived scope of practice by HHC nurses, knowledge gaps and low self-efficacy in depression treatment, stigma attached to depression, poor quality of antidepressant management in primary care, and poor communication between HHC and primary care. Conclusions Strategies to close gaps between typical and best practices need to enhance HHC clinician knowledge and self-efficacy with depression treatment and improve the quality of antidepressant management and communication with primary care.

2016-12-01

According to the U.S. Food and Drug Administration 2013 Model Food Code, it is the duty of a food establishment to disclose and remind consumers of risk when ordering undercooked food such as ground beef. The purpose of this study was to explore actual risk communication behaviors of food establishment servers. Secret shoppers visited 265 restaurants in seven geographic locations across the United States, ordered medium rare burgers, and collected and coded risk information from chain and independent restaurant menus and from server responses. The majority of servers reported an unreliable method of doneness (77%) or other incorrect information (66%) related to burger doneness and safety. These results indicate major gaps in server knowledge and risk communication, and the current risk communication language in the Model Food Code does not sufficiently fill these gaps. The question is "should servers even be acting as risk communicators?" There are numerous challenges associated with this practice, including high turnover rates, limited education, and the high stress environment based on pleasing a customer. If servers are designated as risk communicators, food establishment staff should be adequately trained and provided with consumer advisory messages that are accurate, audience appropriate, and delivered in a professional manner so that customers can make informed food safety decisions.

Mapping Foliar Traits Across Biomes Using Imaging Spectroscopy: A Synthesis

NASA Astrophysics Data System (ADS)

Townsend, P. A.; Singh, A.; Wang, Z.

2016-12-01

One of the great promises of imaging spectroscopy - also known as hyperspectral remote sensing - is the ability to map the spatial variation in foliar functional traits, such as nitrogen concentration, pigments, leaf structure, photosynthetic capacity and secondary biochemistry, that drive terrestrial ecosystem processes. A remote-sensing approach enables characterization of within- and between-biome variations that may be crucial to understanding ecosystem responses to pests, pathogens and environmental change. We provide a synthesis of the foliar traits that can be mapped from imaging spectroscopy, as well as an overview of both the major applications of trait maps derived from hyperspectral imagery and current gaps in our knowledge and capacity. Specifically, we make the case that a global imaging spectroscopy mission will provide unique and urgent measurements necessary to understand the response of agricultural and natural systems to rapid global changes. Finally, we present a quantitative framework to utilize imaging spectroscopy to characterize spatial and temporal variation in foliar traits within and between biomes. From this we can infer the dynamics of vegetation function across ecosystems, especially in transition zones and environmentally sensitive systems. Eventual launch of a global imaging spectroscopy mission will enable collection of narrowband VSWIR measurements that will help close major gaps in our understanding of biogeochemical cycles and improve representation of vegetated biomes in Earth system process models.

Towards the review of the European Union Water Framework ...

EPA Pesticide Factsheets

Water is a vital resource for natural ecosystems and human life, and assuring a high quality of water and protectingit from chemical contamination is a major societal goal in the European Union. The Water Framework Directive(WFD) and its daughter directives are the major body of legislation for the protection and sustainable use of Europeanfreshwater resources. The practical implementation of the WFD with regard to chemical pollution has facedsome challenges. In support of the upcoming WFD review in 2019 the research project SOLUTIONS and the Europeanmonitoring network NORMAN has analyzed these challenges, evaluated the state-of-the-art of the science andsuggested possible solutions. We give 10 recommendations to improve monitoring and to strengthen comprehensiveprioritization, to foster consistent assessment and to support solution-oriented management of surface waters.The integration of effect-based tools, the application of passive sampling for bioaccumulative chemicals and an integratedstrategy for prioritization of contaminants, accounting for knowledge gaps, are seen as important approachesto advance monitoring. Including all relevant chemical contaminants in more holistic “chemical status”assessment, using effect-based trigger values to address priority mixtures of chemicals, to better consider historicalburdens accumulated in sediments and to use models to fill data gaps are recommended for a consistent assessmentof contamination.

Faunal change is a basic and fundamental element in ecology, biogeography, and conservation biology, yet vanishingly few detailed studies have documented such changes rigorously over decadal time scales. This study responds to that gap in knowledge, providing a detailed analysis of Digital Accessible Knowledge of the birds of Mexico, designed to marshal DAK to identify sites that were sampled and inventoried rigorously prior to the beginning of major global climate change (1980). We accumulated DAK records for Mexican birds from all relevant online biodiversity data portals. After extensive cleaning steps, we calculated completeness indices for each 0.05° pixel across the country; we also detected 'hotspots' of sampling, and calculated completeness indices for these broader areas as well. Sites were designated as well-sampled if they had completeness indices above 80% and >200 associated DAK records. We identified 100 individual pixels and 20 broader 'hotspots' of sampling that were demonstrably well-inventoried prior to 1980. These sites are catalogued and documented to promote and enable resurvey efforts that can document events of avifaunal change (and non-change) across the country on decadal time scales. Development of repeated surveys for many sites across Mexico, and particularly for sites for which historical surveys document their avifaunas prior to major climate change processes, would pay rich rewards in information about distributional dynamics of Mexican birds.

Power relations and reciprocity: dialectics of knowledge construction.

PubMed

Ben-Ari, Adital; Enosh, Guy

2013-03-01

In this article we suggest a theoretical framework of knowledge construction by employing the concept of dialectics to power relationships between researcher and participants. Power distribution in research is perceived as dichotomous and asymmetrical in favor of the researcher, creating unequal power relations that make exploitation possible. Acknowledging such exploitation has led to a critical stance and attempts to bridge gaps through egalitarianism and empowerment of participants. Some scholars have focused on shifting expert knowledge differentials between researcher and participants throughout the research project. Others have evaluated such gaps as a source of knowledge construction. In the present work we applied a dialectical approach to understanding research relationships, suggesting reciprocity as their defining attribute, regardless of symmetry or asymmetry and as a source of knowledge construction. In this article we recommend avoiding a taken-for-granted attitude, because we see it as a direct obstacle to the construction of knowledge.

Cybernetics: a possible solution for the "knowledge gap" between "external" and "internal" in evaluation processes.

PubMed

Levin-Rozalis, Miri

2010-11-01

This paper addresses the issue of the knowledge gap between evaluators and the entity being evaluated: the dilemma of the knowledge of professional evaluators vs. the in-depth knowledge of the evaluated subjects. In order to optimize evaluative outcomes, the author suggests an approach based on ideas borrowed from the science of cybernetics as a method of evaluation--one that enables in-depth perception of the evaluated field without jeopardizing a rigorous study or the evaluator's professionalism. The paper focuses on the main concepts that deal with this dilemma--showing how cybernetics combines the different bodies of knowledge of the different stakeholders, including the professional evaluator, resulting in a coherent body of knowledge created mainly by those internal to the process, owned by them, and relevant to all--those who are internal and those who are external and their different purposes.

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.

Gram-negative bacteria are intrinsically resistant to many antibiotics. Species that have acquired multidrug resistance and cause infections that are effectively untreatable present a serious threat to public health. The problem is broadly recognized and tackled at both the fundamental and applied levels. This article summarizes current advances in understanding the molecular bases of the low permeability barrier of Gram-negative pathogens, which is the major obstacle in discovery and development of antibiotics effective against such pathogens. Gaps in knowledge and specific strategies to break this barrier and to achieve potent activities against difficult Gram-negative bacteria are also discussed.

2014-01-01

Conventional water treatment consumes large quantities of coagulant and produces even greater volumes of sludge. Coagulant recovery (CR) presents an opportunity to reduce both the sludge quantities and the costs they incur, by regenerating and purifying coagulant before reuse. Recovery and purification must satisfy stringent potable regulations for harmful contaminants, while remaining competitive with commercial coagulants. These challenges have restricted uptake and lead research towards lower-gain, lower-risk alternatives. This review documents the context in which CR must be considered, before comparing the relative efficacies and bottlenecks of potential technologies, expediting identification of the major knowledge gaps and future research requirements.

Pregnant women are almost always excluded from randomized controlled clinical trials, as the risks to the fetus posed by most new chemical entities or approved drugs cannot be sufficiently ruled out. Hence, a major scientific challenge in this field is to discover and validate alternative tools that will fill the knowledge gap created by the lack of participation in gold-standard randomized trials. This review focuses on novel tools that allow estimation of fetal risks after exposure to therapeutic agents, such as placental perfusion studies, biomarkers of fetal exposure, and novel epidemiological and pharmacogenetic tools, all of which have been tested successfully in recent years.

Timely access and ongoing delivery of care and therapeutic interventions is needed to maximize recovery and function after traumatic spinal cord injury (tSCI). To ensure these decisions are evidence-based, access to consistent, reliable, and valid sources of clinical data is required. The Access to Care and Timing Model used data from the Rick Hansen SCI Registry (RHSCIR) to generate a simulation of healthcare delivery for persons after tSCI and to test scenarios aimed at improving outcomes and reducing the economic burden of SCI. Through model development, we identified knowledge gaps and challenges in the literature and current health outcomes data collection throughout the continuum of SCI care. The objectives of this article were to describe these gaps and to provide recommendations for bridging them. Accurate information on injury severity after tSCI was hindered by difficulties in conducting neurological assessments and classifications of SCI (e.g., timing), variations in reporting, and the lack of a validated SCI-specific measure of associated injuries. There was also limited availability of reliable data on patient factors such as multi-morbidity and patient-reported measures. Knowledge gaps related to structures (e.g., protocols) and processes (e.g., costs) at each phase of care have prevented comprehensive evaluation of system performance. Addressing these knowledge gaps will enhance comparative and cost-effectiveness evaluations to inform decision-making and standards of care. Recommendations to do so were: standardize data element collection and facilitate database linkages, validate and adopt more outcome measures for SCI, and increase opportunities for collaborations with stakeholders from diverse backgrounds.

Methodologies to determine the proliferation resistance (PR) of nuclear facilities often rely on either expert elicitation, a resource-intensive approach without easily reproducible results, or numeric evaluations, which can fail to take into account the institutional knowledge and expert experience of the nonproliferation community. In an attempt to bridge the gap and bring the institutional knowledge into numeric evaluations of PR, a survey was conducted of 33 individuals to find the relative importance of a set of 62 nonproliferation factors, subsectioned into groups under the headings of Diversion, Transportation, Transformation, and Weaponization. One third of the respondents were self-described nonproliferation professionals,more » and the remaining two thirds were from secondary professions related to nonproliferation, such as industrial engineers or policy analysts. The factors were taken from previous work which used multi-attribute utility analysis with uniform weighting of attributes and did not include institutional knowledge. In both expert and non-expert groups, all four headings and the majority of factors had different relative importance at a confidence of 95% (p=0.05). This analysis and survey demonstrates that institutional knowledge can be brought into numeric evaluations of PR, if there is a sufficient investment of resources made prior to the evaluation.« less

Certain dietary supplements (DSs) used by military populations pose a threat to overall readiness. This study assessed members of the American Medical Society for Sports Medicine (AMSSM) regarding their knowledge of DS use among their patients and reporting of suspected adverse events. A thirteen-question retrospective, cross-sectional, Web-based survey sought data on practices regarding DSs and adverse event reporting. Anonymous Web-based survey. Military and civilian sports medicine physicians. The primary finding of the study was how frequently practitioners report adverse events associated with DS use. A total of 311 physicians responded to the survey. Only 51% of respondents had a reliable source for information on DS safety and 58% routinely discussed DS use with their patients. Although a majority (71%) of respondents had encountered adverse events associated with DS use, few of those (10%) confirmed reporting such events. Reasons that physicians did not report adverse events were lack of knowledge regarding where to report (68%), how to report (61%), and availability of time (9%). Our results indicate that some AMSSM physicians are familiar with DSs and have encountered adverse events associated with their use. However, reporting of these adverse events to the appropriate agency is minimal at best. The significant gaps in physician knowledge regarding how and where to report such events indicate a need to educate physicians on this subject. The findings of this survey indicate the need for provider education on reporting adverse events associated with DS use. Although reporting of adverse events is essential for removing harmful DSs from the market, a majority of physicians have limited knowledge on this issue. Moreover, the survey provides insight into the barriers to physician reporting of adverse events.

Cervical cancer-related deaths among women in India are often due to late diagnosis of disease. Knowledge about disease and early screening is the most effective measure for cervical cancer prevention. Lack of awareness, negative attitude, and poor practice about cervical cancer and screening are the major causes to increase the incidence of disease. The study is designed to assess knowledge, attitude, and practice (KAP) toward cervical cancer, screening, and prevention. A cross-sectional, hospital-based survey was conducted in women attending Obstetrics and Gynecology Department of a secondary care referral hospital. A total of 403 subjects were enrolled and subjected for interview using prevalidated KAP questionnaire on cervical cancer. Descriptive statistics were used to represent the sociodemographic characteristics and KAP levels. Association of sociodemographic variables with KAP levels is determined using Chi-square test. Most of (301; 74.6%) the respondents had heard about cervical cancer and majority of them are heard from media (168; 41.6%) and friends (83; 20.5%). Most women knew symptoms (259; 64.2%), risk factors (253; 62.7%), screening methods (310; 76.9%), and preventive measures (249; 61.7%) for cervical cancer. More than half of the women (252; 62.5%) having positive attitude toward screening. More than three-fourth of women (349; 86.6%) are not having practice toward cervical cancer screening. Sociodemographic characteristics are strongly associated with KAP levels. Although women are having good knowledge, positive attitude toward cervical cancer screening and prevention still there is a gap to transform it into practice. There is a need for more educational programs to connect identified knowledge slits and uplift of regular practice of cervical cancer screening.

[Gap junctions: A new therapeutic target in major depressive disorder?].

PubMed

Sarrouilhe, D; Dejean, C

2015-11-01

Major depressive disorder is a multifactorial chronic and debilitating mood disease with high lifetime prevalence and is associated with excess mortality, especially from cardiovascular diseases and through suicide. The treatments of this disease with tricyclic antidepressants and monoamine oxidase inhibitors are poorly tolerated and those that selectively target serotonin and norepinephrine re-uptake are not effective in all patients, showing the need to find new therapeutic targets. Post-mortem studies of brains from patients with major depressive disorders described a reduced expression of the gap junction-forming membrane proteins connexin 30 and connexin 43 in the prefrontal cortex and the locus coeruleus. The use of chronic unpredictable stress, a rodent model of depression, suggests that astrocytic gap junction dysfunction contributes to the pathophysiology of major depressive disorder. Chronic treatments of rats with fluoxetine and of rat cultured cortical astrocytes with amitriptyline support the hypothesis that the upregulation of gap junctional intercellular communication between brain astrocytes could be a novel mechanism for the therapeutic effect of antidepressants. In conclusion, astrocytic gap junctions are emerging as a new potential therapeutic target for the treatment of patients with major depressive disorder. Copyright © 2015 Elsevier Masson SAS.

Magnetic resonance imaging (MRI) is a key diagnostic and monitoring tool in multiple sclerosis (MS) management. However, many scientific uncertainties, especially concerning correlates to impairment and prognosis remain. Little is known about MS patients' experiences, knowledge, attitudes, and unmet information needs concerning MRI. We performed qualitative interviews (n = 5) and a survey (n = 104) with MS patients regarding MRI patient information, and basic MRI knowledge. Based on these findings an interactive training program of 2 hours was developed and piloted in n = 26 patients. Interview analyses showed that patients often feel lost in the MRI scanner and left alone with MRI results and images while 90% of patients in the survey expressed a high interest in MRI education. Knowledge on MRI issues was fair with some important knowledge gaps. Major information interests were relevance of lesions as well as the prognostic and diagnostic value of MRI results. The education program was highly appreciated and resulted in a substantial knowledge increase. Patients reported that, based on the program, they felt more competent to engage in encounters with their physicians. This work strongly supports the further development of an evidence-based MRI education program for MS patients to enhance participation in health-care.

Telephone survey of a representative sample of Australians. Not applicable. Australians aged 18 to 45 years who wish to have a child or another child now or in the future. None. Knowledge about the effect on fertility of age, obesity, smoking, and timing of intercourse. A total of 462 interviews were conducted. The majority of respondents underestimated, by about 10 years, the age at which male and female fertility starts to decline. Only one in four correctly identified that female fertility starts to decline before age 35, and one in three identified that male fertility starts to decline before age 45. Most (59%) were aware that female obesity and smoking affect fertility, but fewer recognized that male obesity (30%) and smoking (36%) also influence fertility. Almost 40% of respondents had inadequate knowledge of when in the menstrual cycle a woman is most likely to conceive. Considerable knowledge gaps about modifiable factors that affect fertility were identified. These are targeted in a national education campaign to promote awareness of factors that influence fertility. Copyright © 2013 American Society for Reproductive Medicine. Published by Elsevier Inc.

2016-01-01

Maternal depression, a non-psychotic depressive episode of mild to major severity, is one of the major contributors of pregnancy-related morbidity and mortality. Maternal depression (antepartum or post partum) has been linked to negative health-related behaviours and adverse outcomes, including psychological and developmental disturbances in infants, children, and adolescents. Despite its enormous burden, maternal depression in low-income and middle-income countries remains under-recognised and undertreated. In this Series paper, we systematically review studies that focus on the epidemiology of perinatal depression (ie, during antepartum and post-partum periods) among women residing in low-income and middle-income countries. We also summarise evidence for the association of perinatal depression with infant and childhood outcomes. This review is intended to summarise fi ndings from the existing literature, identify important knowledge gaps, and set the research agenda for creating new generalisable knowledge pertinent to increasing our understanding of the prevalence, determinants, and infant and childhood health outcomes associated with perinatal depression. This review is also intended to set the stage for subsequent work aimed at reinforcing and accelerating investments toward providing services to manage maternal depression in low-income and middle-income countries.

BACKGROUND Antihistamines are commonly used during pregnancy. There is little evidence that they have teratogenic effects, but there are knowledge gaps with respect to newer products, as well as the relationship between specific antihistamines and specific birth defects. METHODS Using the National Birth Defects Prevention Study (1997-2003), the authors examined associations between maternal use of 14 antihistamines during early pregnancy and 26 isolated major birth defects. A Bayesian analysis incorporating prior knowledge about the relationships between the antihistamines, birth defects, and measured covariates was conducted. RESULTS Of the 364 associations investigated, 24 had 95% posterior intervals excluding 1.0. All 24 associations were positive; 23 associations were of weak to moderate magnitude (posterior odds ratio [OR] < 3.0) and one was strong (OR > 6.0) but very imprecise. Of the 24 associations, 20 were with non-cardiac defects. Eight associations involved the antihistamine diphenhydramine. CONCLUSIONS The results of this study generally were consistent with no association between birth defects and antihistamine use during early pregnancy. Several of the findings might warrant further investigation, although the observed elevated associations should be interpreted in the context of the number of associations investigated and the analysis of retrospective, self-reported data.

Many graduating dentists leave dental school feeling that they are not prepared to start and run a dental practice. The aim of this pilot study was to explore the knowledge and perceptions dental graduates have in the area of practice management. A twenty-item survey was mailed in the fall of 2008 to nearly half of the University of Michigan dental school alumni who had graduated between the years of 1997 and 2007. Respondents were asked about their demographics, practice characteristics, and perceptions of knowledge/experience regarding practice management skills at the present time as well as at graduation. Data were analyzed using descriptive and inferential statistics. The majority of respondents were general practitioners (84 percent) aged thirty to thirty-nine practicing between six and ten years with practice incomes reported to be greater than $300,000 per year (79 percent). Most dentists reported being either an owner or co-owner of the practice (57 percent), and 33 percent reported being an associate in the practice. Upon graduation, 7 percent of the respondents felt that they had a strong knowledge of accounting or human resource issues; this perception increased to 47 percent at the present time. Similarly, less than 6 percent of respondents felt they understood issues pertaining to dental insurance upon graduation; this perception increased to 68 percent after having spent time in the workforce. In contrast to the large increase in knowledge/experience in business aspects of dentistry that had accrued since graduation, most alumni reported only a 7 percent increase in their knowledge of the legal aspects of dental practice. Results from this study indicate that interventions are needed to increase graduating dentists' knowledge of practice management and close the gap between their knowledge and its application in real life. The majority of alumni believed there is a need to improve the curriculum focused on these aspects of dental practice.

We analyzed uncertainties and complexities of the Zika virus outbreak in Brazil, and we discuss risk reduction for future emergencies. We present the public health situation in Brazil and concurrent determinants of the epidemic and the knowledge gaps that persist despite building evidence from research, making public health decisions difficult. Brazil has adopted active measures, but producing desired outcomes may be uncertain because of partial or unavailable information. Reducing population group vulnerabilities and acting on environmental issues are medium- to long-term measures. Simultaneously dealing with information gaps, uncontrolled disease spread, and vulnerabilities is a new risk scenario and must be approached decisively to face emerging biothreats.

Timely injection of knowledge when interacting with stakeholders and policy makers.

Timely injection of knowledge when interacting with stakeholders and policy makers. J.Bouma Em. Prof. Soil Science, Wageningen University, the Netherlands During the last decade, the spectacular development of Information and Communication Technology (ICT) has strongly increased the accessible amount of data and information for stakeholders and policy makers and the science community is struggling to adjust to these developments. In the Netherlands not only industry has now a major impact on the research agenda but this is now to be extended to citizens at large. Rather than complain about an apparent "gap" between science and society and wrestle with the challenge to bridge it in a rather reactive manner, the science community would be well advised to initiate a proactive approach, showing that knowledge implies a deep understanding of issues and processes that does not necessarily follow from having data and information. The "gap" certainly applies to soil research in the context of sustainable development where many often well informed stakeholders are involved with widely different opinions, norms and values. Changes are suggested in the manner in which we frame our work: (i) longer involvement with projects from initiation to implementation in practice; (ii) active role of "knowledge brokers" who inject the right type of knowledge during the entire project run in a joint-learning mode, and (iii) not proposing new research from a science perspective but demonstrating a clear need because existing knowledge is inadequate. Yet more conceptual discussions about e.g. inter- and transdisciplinarity, worrysome soil degradation and lack of professional recognition are less meaningful than specific case studies demonstrating the crucial role of soil science when analysing land-based environmental problems. New narratives are needed instead of statistics, openness to learn from best practices and pilot projects as a necessary next step beyond awareness raising. Soil scientists have a rich history of working with stakeholders. They should re-discover their roots and publications should not only focus on the science alone but also on the societal context in which the studies were made. Much has already been done. It needs to be framed more effectively.

Research to practice in The Journal of Continuing Education in the Health Professions: a thematic analysis of volumes 1 through 24.

MacIntosh-Murray, Anu; Perrier, Laure; Davis, David

2006-01-01

Authors have stressed the importance of the broader contextual influences on practice improvement and learning and have expressed concern about gaps between research and practice. This implies a potential expansion of the knowledge base for continuing education in the health professions (CEHP) and an increased emphasis on research evidence for that knowledge. How has the content of The Journal of Continuing Education in the Health Professions (JCEHP) reflected those changes? What are the implications for CEHP practitioners? Based on all abstracts, tables of contents, and editorials, a thematic analysis was completed for volumes 1 through 24 of JCEHP. All texts were downloaded into qualitative analysis software and coded. Main code categories included demographics of articles, concepts relating to CEHP as a discipline, knowledge translation and outcomes-oriented continuing education, and theories and frameworks. Key themes were identified. Key themes include categories of topics included in JCEHP over the years, the increased prominence of research in JCEHP, a dual research evidence-to-practice gap, the professionalization of continuing education providers, and interdisciplinarity and the links with broader frameworks that have been proposed for CEHP. Two sets of research-to-practice gaps are portrayed in the journal: the gap between clinical research and practice and the gap between research and practice in CEHP. To close the first gap, authors have asserted that the second gap must be addressed, ensuring that CEHP practices themselves are evidence based, driven by theory-based research. This is a variation on prior debates regarding the need to define CEHP as a discipline, which uses the language of professionalization. The increased focus of continuing education on the contexts of health care providers' practices has multiplied the topics that are potentially relevant to CEHP practice.

Although the co-occurrence of nonnative vertebrates is a ubiquitous global phenomenon, the study of interactions between invaders is poorly represented in the literature. Limited understanding of the interactions between co-occurring vertebrates can be problematic for predicting how the removal of only one invasive-a common management scenario-will affect native communities. We suggest a trophic food web framework for predicting the effects of single-species management on native biodiversity. We used a literature search and meta-analysis to assess current understanding of how the removal of one invasive vertebrate affects native biodiversity relative to when two invasives are present. The majority of studies focused on the removal of carnivores, mainly within aquatic systems, which highlights a critical knowledge gap in our understanding of co-occurring invasive vertebrates. We found that removal of one invasive vertebrate caused a significant negative effect on native species compared to when two invasive vertebrates were present. These unexpected results could arise because of the positioning and hierarchy of the co-occurring invasives in the food web (e.g., carnivore-carnivore or carnivore-herbivore). We consider that there are important knowledge gaps to determinate the effects of multiple co-existing invaders on native ecosystems, and this information could be precious for management.

Objectives: To investigate the degree of knowledge chiropractic fourth year interns and post-graduate chiropractic residents have in regard to concussion diagnosis and management. Methods: A survey modified from a study conducted by Boggild and Tator (2012), was administered to fourth year chiropractic interns and post-graduate residents via SurveyMonkey.com. Results: Chiropractic fourth year interns and postgraduate chiropractic specialty college residents scored 5.2 and 5.25 out of 9 respectively, which compares well with Bogglid and Tator’s reports on medical students and residents. Several knowledge gaps were identified in the sample population. Conclusion: The results from this survey show that the concussion knowledge among Canadian fourth year chiropractic interns and specialty college residents compares favorably with the knowledge of fourth year medical students and residents in diagnosing and managing concussions. Chiropractors appear to possess the skills and knowledge to diagnose and manage concussion equal to their medical counterparts. However, knowledge gaps regarding concussion diagnosis and management were found among chiropractic students and residents. PMID:28065987

Since the industrial revolution in the 1800s, plastic pollution is becoming a global reality. This study aims to assess knowledge and attitude about plastic pollution among secondary school students in Sharjah city, United Arab Emirates. A cross-sectional study was conducted among 400 students in 6 different secondary schools in Sharjah city. Self-administered questionnaires were distributed through probability stratified random sampling method between February and April 2016. Majority of the population understands how harmful plastic wastes are to the environment (85.5%). However, the students' mean knowledge score was 53%, with females (P < 0.01), grades 11 and 12 (P = 0.024), and students whose mothers were more educated (P = 0.014) being more knowledgeable and inclined towards pro-environmental behavior. Yet, all students showed tendency to be involved in the fighting against this dilemma. Strategies which address deficiencies, provide incentives for change, and assure governmental support along with environmental education are needed to bridge the information gap and enhance opportunities to adopt pro-environmental behaviors.

Lack of knowledge toward tuberculosis (TB) among health care workers (HCWs) increases the risk of developing TB. The aim of this study was to assess the level of knowledge, attitude, and practice of HCWs in Iran. We conducted a cross-sectional study in 50 universities of medical sciences throughout Iran. A questionnaire was developed to assess the knowledge, attitude, and practice of participants. The values of Cronbach α coefficients for the knowledge and attitude questions were .76 and .75, respectively. The mean scores of knowledge, attitude, and practice among TB laboratory staff regarding TB was 82.6 (95% confidence interval [CI], 82.0-83.7), 87.6 (95% CI, 87.1-88.0), and 57.9 (95% CI, 56.9-58.9), respectively. The mean scores of knowledge, attitude, and practice among non-TB laboratory staff regarding TB was 69.5 (95% CI, 67.9-71.1), 50.7 (95% CI, 50.1-51.4), and 40.82 (95% CI, 38.2-43.4), respectively. TB laboratory staff scored relatively well in knowledge and attitude of TB, but they scored lower in practice regarding TB. Non-TB laboratory staff had lower scores than TB laboratory staff in knowledge, attitude, and practice. There is a major gap between knowledge and attitude and practice in both groups. It is therefore essential to plan for the continuing in-service training of HCWs and public training of the general population regarding TB.

Background The knowledge translation field is undermined by two interrelated gaps – underdevelopment of the science and limited use of research in health services and health systems decision making. The importance of context in theory development and successful translation of knowledge has been identified in past research. Additionally, examination of knowledge translation in the long-term care (LTC) sector has been seriously neglected, despite the fact that aging is increasingly identified as a priority area in health and health services research. Aims The aims of this study are: to build knowledge translation theory about the role of organizational context in influencing knowledge use in LTC settings and among regulated and unregulated caregivers, to pilot knowledge translation interventions, and to contribute to enhanced use of new knowledge in LTC. Design This is a multi-level and longitudinal program of research comprising two main interrelated projects and a series of pilot studies. An integrated mixed method design will be used, including sequential and simultaneous phases to enable the projects to complement and inform one another. Inferences drawn from the quantitative and qualitative analyses will be merged to create meta-inferences. Outcomes Outcomes will include contributions to (knowledge translation) theory development, progress toward resolution of major conceptual issues in the field, progress toward resolution of methodological problems in the field, and advances in the design of effective knowledge translation strategies. Importantly, a better understanding of the contextual influences on knowledge use in LTC will contribute to improving outcomes for residents and providers in LTC settings. PMID:19664285

Epilepsy represents a major health problem in low- and middle-income countries where treatment gap (TG) levels are high. The reduction of epilepsy TG in the rural area of the Chaco region, Plurinational State of Bolivia, has been the aim of many projects based on the reinforcement of the primary care setting. To plan educational campaigns directed to the healthcare professionals, it is necessary to establish their baseline knowledge level. The objective of our study was to assess the baseline level of knowledge, attitudes, and practices (KAP) towards epilepsy among general practitioners (GPs) of the rural communities of the Chaco region. The study was conducted in three departments of Bolivia. All the GPs living in these areas were invited to participate in the study consisting of two training modules six months apart from each other, each with two-day duration. They answered a validated questionnaire to evaluate the KAP towards epilepsy before and after the courses. Fifty GPs [30 men (60%); mean age: 32.1±5.8years] participated in the first training course. After six months, 31 GPs (62%) [19 men (61.3%); mean age: 33±5.0years] participated in the second module. Before the training, the majority of GPs declared a low level of satisfaction about their epilepsy knowledge, which improved after the courses. A change in practices was recorded after the training, with an increased confidence to manage antiepileptic treatment. Our study showed the significant impact of specific training programs on epilepsy among GPs. Copyright © 2017 Elsevier Inc. All rights reserved.

Markets provide a forum for reaching a large adult population with information on Lassa fever, and therefore understanding the food handling practices of traders may provide the foundation for an effective campaign against Lassa fever. This study was undertaken to provide baseline information on knowledge and food handling practices of traders in local markets in a Lassa fever endemic state of Nigeria. A structured questionnaire was used to obtain food handling habits that facilitate the transmission of Lassa virus from a cross sectional study involving 385 traders in three major markets in Edo state and data analyzed using SPSS version 15. Two hundred and ninety three (76.1%) had ever heard of Lassa fever, 27 (9.2%) had good knowledge. Good knowledge was significantly associated with higher educational status (p < 0.00) and male gender (p=0.03). Thirty seven (12.6%) respondents sun-dried their food frequently, 105 (35.8%) stored utensils in rodent proof containers, and 136 (46.4%) had the habit of eating garri soaked in water. One hundred and ninety (49.4%) respondents had food hygiene practices that were favorable for spread of Lassa fever. The observed gaps in knowledge of Lassa fever and food hygiene may be addressed through tailored health messages. In this way, market campaigns will be effective in increasing knowledge of Lassa fever, and traders can themselves become peer educators.

Dental caries is one of the most prevalent and significant health problems in the United States. According to the American Academy of Pediatric Dentistry, more than one-fourth of children between the ages of two and five years experience early childhood caries before entering kindergarten. The purpose of this study was to explore parent’s knowledge of preschool children’s oral health risk factors. A descriptive design was used with a convenience sample of 87 parents of children who attended day care centers and preschools. Seventeen knowledge questions were used to assess parents’ knowledge of their child’s oral health. Results showed that parents lacked knowledge in some aspects of oral health care. The majority of parents knew that baby teeth are important, and both baby and permanent teeth should be brushed. Fewer, however, perceived that cavities in baby teeth lead to cavities in permanent teeth. Similarly, parents knew the role of food in the dental caries, but fewer perceived that cavities may be caused by using a bottle or infant drinking cup to drink fluid other than water and frequent snacking. Findings illuminate the knowledge gaps in this sample of parents of preschoolers. Pediatric nurses can play a key role in promoting children’s oral health and preventing dental caries by proving anticipatory guidance and education to children and their parents at well child visits, during hospitalization, and in school and community settings.

The revised 2014 American College of Cardiology (ACC)/American Heart Association valvular heart disease guidelines provide evidenced-based recommendations for the management of mitral regurgitation (MR). However, knowledge gaps related to our evolving understanding of critical MR concepts may impede their implementation. The ACC conducted a multifaceted needs assessment to characterize gaps, practice patterns, and perceptions related to the diagnosis and treatment of MR. A key project element was a set of surveys distributed to primary care and cardiovascular physicians (cardiologists and cardiothoracic surgeons). Survey and other gap analysis findings were presented to a panel of 10 expert advisors from specialties of general cardiology, cardiac imaging, interventional cardiology, and cardiac surgeons with expertise in valvular heart disease, especially MR, and cardiovascular education. The panel was charged with assessing the relative importance and potential means of remedying identified gaps to improve care for patients with MR. The survey results identified several knowledge and practice gaps that may limit implementation of evidence-based recommendations for MR care. Specifically, half of primary care physicians reported uncertainty regarding timing of intervention for patients with severe primary or functional MR. Physicians in all groups reported that quantitative indices of MR severity were frequently not reported in clinical echocardiographic interpretations, and that these measurements were not consistently reviewed when provided in reports. In the treatment of MR, nearly 30% of primary care physician and general cardiologists did not know the volume of mitral valve repair surgeries by their reference cardiac surgeons and did not have a standard source to obtain this information. After review of the survey results, the expert panel summarized practice gaps into 4 thematic areas and offered proposals to address deficiencies and promote better alignment with the 2014 ACC/American Heart Association valvular disease guidelines. Important knowledge and skill gaps exist that may impede optimal care of the patient with MR. Focused educational and practice interventions should be developed to reduce these gaps.

Specificity of learning: why infants fall over a veritable cliff.

PubMed

Adolph, K E

2000-07-01

Nine-month-old infants were tested at the precipice of safe and risky gaps in the surface of support. Their reaching and avoidance responses were compared in two postures, an experienced sitting posture and a less familiar crawling posture. The babies avoided reaching over risky gaps in the sitting posture but fell into risky gaps while attempting to reach in the crawling posture. This dissociation between developmental changes in posture suggests that (a) each postural milestone represents a different, modularly organized control system and (b) infants' adaptive avoidance responses are based on information about their postural stability relative to the gap size. Moreover, the results belie previous accounts suggesting that avoidance of a disparity in depth of the ground surface depends on general knowledge such as fear of heights, associations between depth information and falling, or knowledge that the body cannot be supported in empty space.

The underassessment and undertreatment of pain in residents of long-term care (LTC) facilities has been well documented. Gaps in staff knowledge and inaccurate beliefs have been identified as contributors. To investigate the effectiveness of an expert-based continuing education program in pain assessment⁄management for LTC staff. Participants included 131 LTC staff members who were randomly assigned to either an interactive pain education (PE) program, which addressed gaps in knowledge such as medication management, or an interactive control program consisting of general dementia education without a specific clinical focus. Participants attended three sessions, each lasting 3 h, and completed measures of pain-related knowledge and attitudes⁄beliefs before, immediately after and two weeks following the program. Focus groups were conducted with a subset of participants to gauge perception of the training program and barriers to implementing pain-related strategies. Analysis using ANOVA revealed that PE participants demonstrated larger gains compared with control participants with regard to pain knowledge and pain beliefs. Barriers to implementing pain-related strategies certainly exist. Nonetheless, qualitative analyses demonstrated that PE participants reported that they overcame many of these barriers and used pain management strategies four times more frequently than control participants. Contrary to previous research, the present study found that the interactive PE program was effective in changing pain beliefs and improving knowledge. Continuing PE in LTC has the potential to address knowledge gaps among front-line LTC providers.

Background: Rapid economic development in China has produced serious ecological, environmental, and health problems. Neurotoxicity has been recognized as a major public health problem. The Chinese government, research institutes, and scientists conducted extensive studies concerning the source, characteristics, and mechanisms of neurotoxicants. Objectives: This paper presents, for the first time, a comprehensive history and review of major sources of neurotoxicants, national bodies/legislation engaged, and major neurotoxicology research in China. Methods: Peer-reviewed research and pollution studies by Chinese scientists from 1991 to 2015 were examined. PubMed, Web of Science and Chinese National Knowledge Infrastructure (CNKI) were the major search tools. Results: The central problem is an increased exposure to neurotoxicants from air and water, food contamination, e-waste recycling, and manufacturing of household products. China formulated an institutional framework and standards system for management of major neurotoxicants. Basic and applied research was initiated, and international cooperation was achieved. The annual number of peer-reviewed neurotoxicology papers from Chinese authors increased almost 30-fold since 2001. Conclusions: Despite extensive efforts, neurotoxicity remains a significant public health problem. This provides great challenges and opportunities. We identified 10 significant areas that require major educational, environmental, governmental, and research efforts, as well as attention to public awareness. For example, there is a need to increase efforts to utilize new in vivo and in vitro models, determine the potential neurotoxicity and mechanisms involved in newly emerging pollutants, and examine the effects and mechanisms of mixtures. In the future, we anticipate working with scientists worldwide to accomplish these goals and eliminate, prevent and treat neurotoxicity. Citation: Cai T, Luo W, Ruan D, Wu YJ, Fox DA, Chen J. 2016.

Mind the gap - do we need more geoscientific expertise for developing R?

R has reached a high level of acceptance and usage among geoscientists worldwide, including both users and developers. These two groups are not mutually exclusive but overlap strongly. This is a favourable situation to promote the implementation of new functionalities as packages and shared scripts. Despite this positive trend there is a series of missing functionalities. Likewise, other languages, such as Python, Matlab, C++ or FORTRAN, provide similar possibilities like R and have been used for addressing needs for such missing functionalities already long ago. R allows in principal to implement such lacking functionalities - but only if they have been identified and communicated amongst the community in a transparent way. Our session addresses this challenge. The PICO presentation gives a brief overview of the directions of R functionalities in the field of geosciences and identifies major gaps, from the viewpoint of us session conveners and most importantly based on the input of participating scientists. We invite all scientists to discuss and contribute knowledge to this topic based on their experiences and requirements. The suggestions will be broadcast as live updates during the PICO session and beyond. We intend to work towards building an active community of interacting developers and users to fill identified gaps to develop new powerful functionalities in the R environment.

Decision Making Under Uncertainty - Bridging the Gap Between End User Needs and Science Capability

NASA Astrophysics Data System (ADS)

Verdon-Kidd, D. C.; Kiem, A.; Austin, E. K.

Successful adaptation outcomes depend on decision making based on the best available climate science information. However, a fundamental barrier exists, namely the 'gap' between information that climate science can currently provide and the information that is practically useful for end users and decision makers. This study identifies the major contributing factors to the 'gap' from an Australian perspective and provides recommendations as to ways in which the 'gap' may be narrowed. This was achieved via a literature review, online survey (targeted to providers of climate information and end users of that information), workshop (where both climate scientists and end users came together to discuss key issues) and focus group. The study confirmed that uncertainty in climate science is a key barrier to adaptation. The issue of uncertainty was found to be multi-faceted, with issues identified in terms of communication of uncertainty, misunderstanding of uncertainty and the lack of tools/methods to deal with uncertainty. There were also key differences in terms of expectations for the future - most end users were of the belief that uncertainty associated with future climate projections would reduce within the next five to 10 years, however producers of climate science information were well aware that this would most likely not be the case. This is a concerning finding as end users may delay taking action on adaptation and risk planning until the uncertainties are reduced - a situation which may never eventuate or may occur after the optimal time for action. Improved communication and packaging of climate information was another key theme that was highlighted in this study. Importantly, it was made clear that improved communication is not just about more glossy brochures and presentations by climate scientists, rather there is a role for a program or group to fill this role (coined a 'knowledge broker' during the workshop and focus group). The role of the 'knowledge broker' would be to package, translate (both from end user to scientist and scientist to end user) and transform climate information. Importantly communication of uncertainty needs to be improved so that end users are aware of all the caveats and what can realistically be expected from climate science now and in the near future. Overall this study confirmed that there is indeed a 'gap' between end user's needs and science capability, particularly with respect to uncertainty, communication and packaging of climate information. This 'gap' has been a barrier to successful climate change adaptation in the past. While it is unrealistic to think we could ever close the 'gap' completely, based on the recommendations provided in this paper, it may be possible to bridge the 'gap' (or at least improve people's awareness of the 'gap'). Furthermore, the insights gained and recommendations provided from this study, while based on an Australian context, are likely to be applicable to many other regions of the world, grappling with similar issues.

Contextualized analysis of a needs assessment using the Theoretical Domains Framework: a case example in endocrinology

PubMed Central

2014-01-01

Background The Theoretical Domains Framework (TDF) is a set of 14 domains of behavior change that provide a framework for the critical issues and factors influencing optimal knowledge translation. Considering that a previous study has identified optimal knowledge translation techniques for each TDF domain, it was hypothesized that the TDF could be used to contextualize and interpret findings from a behavioral and educational needs assessment. To illustrate this hypothesis, findings and recommendations drawn from a 2012 national behavioral and educational needs assessment conducted with healthcare providers who treat and manage Growth and Growth Hormone Disorders, will be discussed using the TDF. Methods This needs assessment utilized a mixed-methods research approach that included a combination of: [a] data sources (Endocrinologists (n:120), Pediatric Endocrinologists (n:53), Pediatricians (n:52)), [b] data collection methods (focus groups, interviews, online survey), [c] analysis methodologies (qualitative - analyzed through thematic analysis, quantitative - analyzed using frequencies, cross-tabulations, and gap analysis). Triangulation was used to generate trustworthy findings on the clinical practice gaps of endocrinologists, pediatric endocrinologists, and general pediatricians in their provision of care to adult patients with adult growth hormone deficiency or acromegaly, or children/teenagers with pediatric growth disorders. The identified gaps were then broken into key underlying determinants, categorized according to the TDF domains, and linked to optimal behavioral change techniques. Results The needs assessment identified 13 gaps, each with one or more underlying determinant(s). Overall, these determinants were mapped to 9 of the 14 TDF domains. The Beliefs about Consequences domain was identified as a contributing determinant to 7 of the 13 challenges. Five of the gaps could be related to the Skills domain, while three were linked to the Knowledge domain. Conclusions The TDF categorization of the needs assessment findings allowed recommendation of appropriate behavior change techniques for each underlying determinant, and facilitated communication and understanding of the identified issues to a broader audience. This approach provides a means for health education researchers to categorize gaps and challenges identified through educational needs assessments, and facilitates the application of these findings by educators and knowledge translators, by linking the gaps to recommended behavioral change techniques.

2017-01-01

Acquired epilepsies can arise as a consequence of brain injury and result in unprovoked seizures that emerge after a latent period of epileptogenesis. These epilepsies pose a major challenge to clinicians as they are present in the majority of patients seen in a common outpatient epilepsy clinic and are prone to pharmacoresistance, highlighting an unmet need for new treatment strategies. Metabolic and homeostatic changes are closely linked to seizures and epilepsy, although, surprisingly, no potential treatment targets to date have been translated into clinical practice. We summarize here the current knowledge about metabolic and homeostatic changes in seizures and acquired epilepsy, maintaining a particular focus on mitochondria, calcium dynamics, reactive oxygen species and key regulators of cellular metabolism such as the Nrf2 pathway. Finally, we highlight research gaps that will need to be addressed in the future which may help to translate these findings into clinical practice. PMID:28885567

China has seen the largest human migration in history, and the country's rapid urbanisation has important consequences for public health. A provincial analysis of its urbanisation trends shows shifting and accelerating rural-to-urban migration across the country and accompanying rapid increases in city size and population. The growing disease burden in urban areas attributable to nutrition and lifestyle choices is a major public health challenge, as are troubling disparities in health-care access, vaccination coverage, and accidents and injuries in China's rural-to-urban migrant population. Urban environmental quality, including air and water pollution, contributes to disease both in urban and in rural areas, and traffic-related accidents pose a major public health threat as the country becomes increasingly motorised. To address the health challenges and maximise the benefits that accompany this rapid urbanisation, innovative health policies focused on the needs of migrants and research that could close knowledge gaps on urban population exposures are needed.

Leptospirosis is a zoonotic disease, which has become a major public health threat in Sri Lanka. A majority of patients are farmers in rural endemic areas. The purpose of the present study is to describe the level of knowledge and frequencies of risky practices related to leptospirosis among a sample of rural school adolescents in Galgamuwa, Kurunegala district, a highly endemic area in Sri Lanka. A descriptive cross-sectional study was conducted among 460 adolescents studying in grades 9 and 10 of government schools. Study participants were selected using a multistage cluster sampling technique. A structured, pretested, self-administered questionnaire was used to collect data on sociodemographic characteristics, knowledge on leptospirosis, and frequency of associated risky practices related to leptospirosis. The response rate was 100%. Fifty-two percent of respondents had a 'good' level of knowledge of leptospirosis. In the assessment of practices, 62% were involved in rice paddy cultivation either 'frequently' or 'rarely'. Seventy percent of the fathers and 50% of the mothers of the students were involved in paddy cultivation. Thirteen percent reported that they swam, bathed, or washed in ponds of stagnant water. Of the students involved in paddy cultivation, only 18% said they usually used gloves and boots 'frequently'. Among the 9% of students who handled cattle or buffalo, 61% reported washing their hands and feet after handling the animals. Good level of knowledge was significantly associated with involvement in paddy cultivation among the adolescents (p=0.45), fathers (p<0.001), and mothers (p=0.012). The level of knowledge was not significantly associated with practicing preventive measures for leptospirosis. Although the respondent's overall level of knowledge regarding leptospirosis was satisfactory, the study identified several important gaps in specific areas. Those who were involved or had parents involved in paddy cultivation had better knowledge. However, this knowledge was not translated into practice of personal preventive measures. Use of protective attire in paddy farming needs to be facilitated by health authorities.

There are big gaps in our knowledge, and thus approach, to zoo animal welfare: a case for evidence-based zoo animal management.

PubMed

Melfi, V A

There are gaps in knowledge that hinder our ability within zoos to provide good animal welfare. This does not mean that zoos cannot or do not provide good welfare, only that currently this goal is hindered. Three reasons for these gaps are identified as: (1) there is an emphasis on the identification and monitoring of indicators that represent poor welfare and it is assumed that an absence of poor welfare equates to good welfare. This assumption is overly simplistic and potentially erroneous; (2) our understanding of how housing and husbandry (H&H) affects animals is limited to a small set of variables determined mostly by our anthropogenic sensitivities. Thus, we place more value on captive environmental variables like space and companionship, ignoring other factors that may have a greater impact on welfare, like climate; (3) finally, whether intentional or not, our knowledge and efforts to improve zoo animal welfare are biased to very few taxa. Most attention has been focused on mammals, notably primates, large cats, bears, and elephants, to the exclusion of the other numerous species about which very little is known. Unfortunately, the extent to which these gaps limit our ability to provide zoo animals with good welfare is exacerbated by our over reliance on using myth and tradition to determine zoo animal management. I suggest that we can fill these gaps in our knowledge and improve our ability to provide zoo animals with good welfare through the adoption of an evidence-based zoo animal management framework. This approach uses evidence gathered from different sources as a basis for making any management decisions, as good quality evidence increases the likelihood that these decisions result in good zoo animal welfare.

Electronic patient records in action: Transforming information into professionally relevant knowledge.

PubMed

Winman, Thomas; Rystedt, Hans

2011-03-01

The implementation of generic models for organizing information in complex institutions like those in healthcare creates a gap between standardization and the need for locally relevant knowledge. The present study addresses how this gap can be bridged by focusing on the practical work of healthcare staff in transforming information in EPRs into knowledge that is useful for everyday work. Video recording of shift handovers on a rehabilitation ward serves as the empirical case. The results show how extensive selections and reorganizations of information in EPRs are carried out in order to transform information into professionally relevant accounts. We argue that knowledge about the institutional obligations and professional ways of construing information are fundamental for these transitions. The findings point to the need to consider the role of professional knowledge inherent in unpacking information in efforts to develop information systems intended to bridge between institutional and professional boundaries in healthcare. © The Author(s) 2011.

Haddal, Risa; Jones, Rebecca; Bersell, Bridget

In 2017, four U.S. National Laboratories collaborated on behalf of DOE/NNSA to explore the safeguards knowledge retention problem, identify possible approaches, and develop a strategy to address it. The one-year effort consisted of four primary tasks. First, the project sought to identify critical safeguards information at risk of loss. Second, a survey and workshop were conducted to assess nine U.S. National Laboratories' efforts to determine current safeguards knowledge retention practices and challenges, and identify best practices. Third, specific tools were developed to identify and predict critical safeguards knowledge gaps and how best to recruit in order to fill those gaps.more » Finally, based on findings from the first three tasks and research on other organizational approaches to address similar issues, a strategy was developed on potential knowledge retention methods, customized HR policies, and best practices that could be implemented across the National Laboratory Complex.« less

Medical reviews and research comprise a key information source for news media stories on medical therapies and innovations as well as for physicians in updating their practice. The present study examined medical review journal articles, physician surveys and news media coverage of hormone replacement therapy (HT) to assess the relationship between the three information sources and whether/if they contributed to a state-of-the-science gap (a condition when the evaluation of a medical condition or therapy ascertained by the highest standards of investigation is incongruent with the science-in-practice such as physician recommendations and patient actions). We content-analyzed 177 randomly sampled HT medical reviews between 2002 and 2014, and HT news valence in three major TV networks, newspapers and magazines/internet sites in 2002-2003, 2008-2009 and 2012-14. The focus in both analyses was whether HT benefits outweighed risks, risks outweighed benefits or both risks and benefits were presented. We also qualitatively content-analyzed all 19 surveys of US physicians' HT recommendations from 2002 to 2009, and 2012 to 2014. Medical reviews yielded a mixed picture about HT (40.1% benefits, 26.0% risks, and 33.9% both benefits and risks). While a majority of physician surveys were pro-HT 10/19), eight showed varied attitudes and one was negative. Newspaper and television coverage reflected a pro and con balance while magazine stories were more positive in the later reporting period. Medical journal review articles, physicians, and media reports all provide varying view points towards hormone therapy use thus leading to limited knowledge about the actual risks and benefits of HT among peri- and menopausal women and a state-of-the-science gap.

Improving access to care for children with mental disorders: a global perspective.

Developmental disabilities, emotional disorders and disruptive behaviour disorders are the leading mental health-related causes of the global burden of disease in children aged below 10 years. This article aims to address the treatment gap for child mental disorders through synthesising three bodies of evidence: the global evidence base on the treatment of these priority disorders; the barriers to implementation of this knowledge; and the innovative approaches taken to address these barriers and improve access to care. Our focus is on low-resource settings, which are mostly found in low- and middle-income countries (LMIC). Despite the evidence base on the burden of child mental disorders and their long-term consequences, and the recent mental health Gap Action Programme guidelines which testify to the effectiveness of a range of pharmacological and psychosocial interventions for these disorders, the vast majority of children in LMIC do not have access to these interventions. We identify three major barriers for the implementation of efficacious treatments: the lack of evidence on delivery of the treatments, the low levels of detection of child mental disorders and the shortage of skilled child mental health professionals. The evidence based on implementation, although weak, supports the use of screening measures for detection of probable disorders, coupled with a second-stage diagnostic assessment and the use of non-specialist workers in community and school settings for the delivery of psychosocial interventions. The most viable strategy to address the treatment gap is through the empowerment of existing human resources who are most intimately concerned with child care, including parents, through innovative technologies, such as mobile health, with the necessary skills for the detection and treatment of child mental disorders.

2014-01-01

Background The WHO’s mental health Gap Action Programme seeks to narrow the treatment gap for mental disorders by advocating integration of mental health into primary health care (PHC). This study aimed to assess the challenges and opportunities of this approach from the perspective of PHC workers in a sub-Saharan African country. Methods A facility-based cross-sectional survey of 151 PHC workers was conducted from 1st to 30th November 2011 in Jimma zone, south-west Ethiopia. A structured questionnaire was used to ask about past training and mental health experience, knowledge and attitudes towards mental disorders and provision of mental health care in PHC. Semi-structured interviews were carried out with 12 heads of health facilities for more in-depth understanding. Results Almost all PHC workers (96.0%) reported that mental health care was important in Ethiopia and the majority (66.9%) expressed interest in actually delivering mental health care. Higher levels of general health training (degree vs. diploma) and pre-service clinical exposure to mental health care were associated with more favourable attitudes. Knowledge about mental disorder diagnoses, symptoms and treatments was low. Almost half (45.0%) of PHC workers reported that supernatural factors were important causes of mental disorders. Health system and structural issues, such as poor medication supply, lack of rooms, time constraints, absence of specialist supervision and lack of treatment guidelines, were identified as challenges. Almost all PHC workers (96.7%) reported a need for more training, including a clinical attachment, in order to be able to deliver mental health care competently. Conclusions Despite acceptability to PHC workers, the feasibility of integrating mental health into PHC in this sub-Saharan African setting is limited by important gaps in PHC worker knowledge and expectations regarding mental health care, coupled with health system constraints. In addition to clinically-based refresher mental health training, expansion of the specialist mental health workforce may be needed to support integration in practice. PMID:24602215

Mediterranean Sea is facing a very high risk of oil pollution due to the high number of oil extractive and refining sites along the basin coasts, and the intense maritime traffic of oil tankers. All the Mediterranean countries have adopted severe regulations for minimizing pollution events and bioremediation feasibility studies for the most urgent polluted sites are undergoing. However, the analysis of the scientific studies applying modern 'meta-omics' technologies that have been performed on marine oil pollution worldwide showed that the Southern Mediterranean side has been neglected by the international research. Most of the studies in the Mediterranean Sea have been done in polluted sites of the Northern side of the basin. Those of the Southern side are poorly studied, despite many of the Southern countries being major oil producers and exporters. The recently EU-funded research project ULIXES has as a major objective to increase the knowledge of the bioremediation potential of sites from the Southern Mediterranean countries. ULIXES is targeting four major polluted sites on the coastlines of Egypt, Jordan, Morocco and Tunisia, including seashore sands, lagoons, and oil refinery polluted sediments. The research is designed to unravel, categorize, catalogue, exploit and manage the diversity and ecology of microorganisms thriving in these polluted sites. Isolation of novel hydrocarbon degrading microbes and a series of state of the art 'meta-omics' technologies are the baseline tools for improving our knowledge on biodegradation capacities mediated by microbes under different environmental settings and for designing novel site-tailored bioremediation approaches. A network of twelve European and Southern Mediterranean partners is cooperating for plugging the existing gap of knowledge for the development of novel bioremediation processes targeting such poorly investigated polluted sites.

A wide variety of medical imaging techniques pervade modern medicine, and the changing portability and performance of tools like ultrasound imaging have brought these medical imaging techniques into the everyday practice of many specialties outside of radiology. However, proper interpretation of ultrasonographic and computed tomographic images requires the practitioner to not only hone certain technical skills, but to command an excellent knowledge of sectional anatomy and an understanding of the pathophysiology of the examined areas as well. Yet throughout many medical curricula there is often a large gap between traditional anatomy coursework and clinical training in imaging techniques. The authors present a radiological anatomy course developed to teach sectional anatomy with particular emphasis on ultrasonography and computed tomography, while incorporating elements of medical simulation. To assess students' overall opinions about the course and to examine its impact on their self-perceived improvement in their knowledge of radiological anatomy, anonymous evaluation questionnaires were provided to the students. The questionnaires were prepared using standard survey methods. A five-point Likert scale was applied to evaluate agreement with statements regarding the learning experience. The majority of students considered the course very useful and beneficial in terms of improving three-dimensional and cross-sectional knowledge of anatomy, as well as for developing practical skills in ultrasonography and computed tomography. The authors found that a small-group, hands-on teaching model in radiological anatomy was perceived as useful both by the students and the clinical teachers involved in their clinical education. In addition, the model was introduced using relatively few resources and only two faculty members.

Farmers' markets are increasingly popular venues in North America for the sale of fresh produce and other foods. However, the nature of their operation can present possible food safety issues, challenges, and risks to consumers. A knowledge synthesis was conducted to identify, characterize, and summarize published research on the microbial food safety issues and implications associated with farmers' markets. A scoping review was conducted using the following steps: comprehensive search strategy, relevance screening of abstracts, and characterization of relevant articles. Two subsets of data were prioritized for more detailed systematic review (data extraction and risk-of-bias assessment) and meta-analysis: (i) studies comparing the microbial safety of foods from farmers' markets versus other sources and (ii) studies evaluating the use of food safety practices at farmers' markets. Overall, 83 relevant studies were identified. The majority of studies were published as journal articles (64%), used a cross-sectional design (81%), and were conducted in the United States (78%). Most studies (39%; n = 32) investigated stakeholder, mostly consumer (n = 22), attitudes toward food safety at farmers' markets. Limited but heterogeneous evidence indicated a higher prevalence of Campylobacter and Salmonella in chicken meat from farmers' markets versus other retail sources, but there was no difference in the microbial contamination of fresh produce. Studies evaluating the use of food safety practices at farmers' markets identified some gaps; for example, the average prevalence of vendor hand washing was 4% (95% confidence interval: 0 to 11%; I 2 = 27%; n = 5 studies). Twelve foodborne outbreaks and case reports were identified, resulting in a total of 411 illnesses, 38 hospitalizations, and two deaths from 1994 to 2016. Only five intervention studies were identified. Key knowledge gaps and areas warranting future research, training, and education are highlighted and discussed.

Scoping Review of the Zika Virus Literature

PubMed Central

2016-01-01

The global primary literature on Zika virus (ZIKV) (n = 233 studies and reports, up to March 1, 2016) has been compiled using a scoping review methodology to systematically identify and characterise the literature underpinning this broad topic using methods that are documented, updateable and reproducible. Our results indicate that more than half the primary literature on ZIKV has been published since 2011. The articles mainly covered three topic categories: epidemiology of ZIKV (surveillance and outbreak investigations) 56.6% (132/233), pathogenesis of ZIKV (case symptoms/ outcomes and diagnosis) 38.2% (89/233) and ZIKV studies (molecular characterisation and in vitro evaluation of the virus) 18.5% (43/233). There has been little reported in the primary literature on ZIKV vectors (12/233), surveillance for ZIKV (13/233), diagnostic tests (12/233) and transmission (10/233). Three papers reported on ZIKV prevention/control strategies, one investigated knowledge and attitudes of health professionals and two vector mapping studies were reported. The majority of studies used observational study designs, 89.7% (209/233), of which 62/233 were case studies or case series, while fewer (24/233) used experimental study designs. Several knowledge gaps were identified by this review with respect to ZIKV epidemiology, the importance of potential non-human primates and other hosts in the transmission cycle, the burden of disease in humans, and complications related to human infection with ZIKV. Historically there has been little research on ZIKV; however, given its current spread through Australasia and the Americas, research resources are now being allocated to close many of the knowledge gaps identified in this scoping review. Future updates of this project will probably demonstrate enhanced evidence and understanding of ZIKV and its impact on public health. PMID:27244249

The aim of this article is to present an overview of salient issues of exposure, characterisation and hazard assessment of nanomaterials as they emerged from the consensus-building of experts undertaken within the four year European Commission coordination project NanoImpactNet. The approach adopted is to consolidate and condense the findings and problem-identification in such a way as to identify knowledge-gaps and generate a set of interim recommendations of use to industry, regulators, research bodies and funders. The categories of recommendation arising from the consensual view address: significant gaps in vital factual knowledge of exposure, characterisation and hazards; the development, dissemination and standardisation of appropriate laboratory protocols; address a wide range of technical issues in establishing an adequate risk assessment platform; the more efficient and coordinated gathering of basic data; greater inter-organisational cooperation; regulatory harmonization; the wider use of the life-cycle approaches; and the wider involvement of all stakeholders in the discussion and solution-finding efforts for nanosafety.

2016-01-01

Background 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. Methodology 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. Principal Findings 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. Conclusions/Significance 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.

Arizona Registered Dietitians Show Gaps in Knowledge of Bean Health Benefits

PubMed Central

Thompson, Sharon V.; Dougherty, Mariah K.

2018-01-01

Registered Dietitians (RDs) promote nutrition practices and policies and can influence food consumption patterns to include nutrient dense foods such as beans. Although many evidence-based health benefits of bean consumption (e.g., cholesterol reduction, glycemic control) have been demonstrated, there is limited research on the knowledge, attitudes, and perceptions of RDs regarding the inclusion of beans in a healthy diet. To fill this existing research gap, this cross-sectional survey explored the perceptions, knowledge, and attitudes of 296 RDs in Arizona, USA, toward beans. The RDs largely held positive attitudes toward the healthfulness of beans and were aware of many health benefits. Some gaps in awareness were evident, including effect on cancer risk, intestinal health benefits, folate content, and application with celiac disease patients. RDs with greater personal bean consumption had significantly higher bean health benefit knowledge. Twenty-nine percent of the RDs did not know the meaning of ‘legume’, and over two-thirds could not define the term ‘pulse’. It is essential that RDs have up-to-date, evidence-based information regarding bean benefits to provide appropriate education to patients, clients, and the public. PMID:29316699

Stress, Time Pressure, Strategy Selection and Math Anxiety in Mathematics: A Review of the Literature.

2017-01-01

We review how stress induction, time pressure manipulations and math anxiety can interfere with or modulate selection of problem-solving strategies (henceforth "strategy selection") in arithmetical tasks. Nineteen relevant articles were identified, which contain references to strategy selection and time limit (or time manipulations), with some also discussing emotional aspects in mathematical outcomes. Few of these take cognitive processes such as working memory or executive functions into consideration. We conclude that due to the sparsity of available literature our questions can only be partially answered and currently there is not much evidence of clear associations. We identify major gaps in knowledge and raise a series of open questions to guide further research.

PIWIs Go Viral: Arbovirus-Derived piRNAs in Vector Mosquitoes

PubMed Central

2016-01-01

Vector mosquitoes are responsible for transmission of the majority of arthropod-borne (arbo-) viruses. Virus replication in these vectors needs to be sufficiently high to permit efficient virus transfer to vertebrate hosts. The mosquito immune response therefore is a key determinant for arbovirus transmission. Mosquito antiviral immunity is primarily mediated by the small interfering RNA pathway. Besides this well-established antiviral machinery, the PIWI-interacting RNA (piRNA) pathway processes viral RNA into piRNAs. In recent years, significant progress has been made in characterizing the biogenesis and function of these viral piRNAs. In this review, we discuss these developments, identify knowledge gaps, and suggest directions for future research. PMID:28033427

New clinical practice guidelines on the classification, evaluation and management of childhood interstitial lung disease in infants: what do they mean?

PubMed

Wambach, Jennifer A; Young, Lisa R

2014-12-01

The American Thoracic Society (ATS) recently published a clinical practice guideline regarding the classification, evaluation, and management of childhood interstitial lung disease in infancy (chILD). As disease entities among infants with ILD are often distinct from forms seen in older children and adults, the guideline encourages an age-based classification system and focuses on the diagnostic approach to neonates and infants <2 years of age. The guideline reviews current evidence and recommendations for the evaluation, relevant genetic studies, and management of symptomatic infants. Here, we summarize the ATS guideline, highlight the major concepts, and discuss future strategies aimed at addressing current gaps in knowledge.

In 2008, the Institute of Medicine reviewed NASA's Human Research Program Evidence in assessing the Pharmacology risk identified in NASA's Human Research Program Requirements Document (PRD). Since this review there was a major reorganization of the Pharmacology discipline within the HRP, as well as a re-evaluation of the Pharmacology evidence. This panel is being asked to review the latest version of the Pharmacology Evidence Report. Specifically, this panel will: (1) Appraise the descriptions of the human health-related risk in the HRP PRD. (2) Assess the relevance and comprehensiveness of the evidence in identifying potential threats to long-term space missions. (3) Assess the associated gaps in knowledge and identify additional areas for research as necessary.

Lack of African American females in breast cancer research has been receiving substantial attention. This study seeks to identify research perceptions and motivating factors needed to increase racial/ethnic minority participation in breast cancer research. A total of 57 African American women (Σ = 47.8 years), from Rhode Island and Texas, completed a questionnaire and focus group. While many participants were not breast cancer survivors, they reported knowledge of their racial group's risk for breast cancer. One major finding that could be seen as both a facilitator and barrier is racial concordance between participant and researcher. Cultural sensitivity and trust building is recommended to increase minority participation.

Navarro-Sigüenza, Adolfo G.; Martínez-Meyer, Enrique

2016-01-01

Background Faunal change is a basic and fundamental element in ecology, biogeography, and conservation biology, yet vanishingly few detailed studies have documented such changes rigorously over decadal time scales. This study responds to that gap in knowledge, providing a detailed analysis of Digital Accessible Knowledge of the birds of Mexico, designed to marshal DAK to identify sites that were sampled and inventoried rigorously prior to the beginning of major global climate change (1980). Methods We accumulated DAK records for Mexican birds from all relevant online biodiversity data portals. After extensive cleaning steps, we calculated completeness indices for each 0.05° pixel across the country; we also detected ‘hotspots’ of sampling, and calculated completeness indices for these broader areas as well. Sites were designated as well-sampled if they had completeness indices above 80% and >200 associated DAK records. Results We identified 100 individual pixels and 20 broader ‘hotspots’ of sampling that were demonstrably well-inventoried prior to 1980. These sites are catalogued and documented to promote and enable resurvey efforts that can document events of avifaunal change (and non-change) across the country on decadal time scales. Conclusions Development of repeated surveys for many sites across Mexico, and particularly for sites for which historical surveys document their avifaunas prior to major climate change processes, would pay rich rewards in information about distributional dynamics of Mexican birds.

Inappropriate antibiotics prescription in dental healthcare delivery that may result in the emergence of antibiotic-resistant bacteria, is a worldwide concern. The objective of the study was to determine the antibiotics knowledge and prescription patterns among dentists in Nigeria. A total of 160 questionnaires were distributed to dentists attending continuing education courses organized by two organizations in Southern and Northern parts of Nigeria. Data analysis was done using SPSS version 17.0. A total of 146 questionnaires were returned, properly filled, out of 160 questionnaires, giving an overall response rate 91.3%. The clinical factors predominantly influenced the choice of therapeutic antibiotics among the respondents. In this study, the most commonly prescribed antibiotics among the respondents was a combination of amoxicillin and metronidazole. Of the respondents, 136 (93.2%) of them considered antibiotic resistance as a major problem in Nigeria and 102 (69.9%) have experienced antibiotics resistance in dental practice. The major reported conditions for prophylactic antibiotics among the respondents were diabetic mellitus, HIV/AIDS, history of rheumatic fever, other heart anomalies presenting with heart murmur and presence of prosthetic hip. The knowledge of adverse effects of antibiotics was greatest for tooth discoloration which is related to tetracycline. Data from this study revealed the most commonly prescribed antibiotics as a combination of amoxicillin and metronidazole. There existed gaps in prophylactic antibiotic prescription, consideration in the choice of therapeutic antibiotics and knowledge of adverse effects of antibiotics among the studied dentists.

In the absence of empirical literature from the resident perspective, this study provided a first assessment of smoking history, knowledge of the risks of smoking, the risks of environmental tobacco exposure, and the benefits of quitting among older (age 50+) nursing home unit residents, as well as readiness to quit, barriers to quitting, frequency of cessation advice by healthcare givers, and quit-attempt history of residents who smoke. Subjects were 25 smokers and 70 non-smokers housed on long-term nursing home units in a county hospital. Results indicated that smoking status for the majority of residents was similar to when they were admitted, although smokers smoked fewer cigarettes (M = 11.6, SD = 9.2) than prior to admission (M = 18.6, SD = 11.8). Smokers were less likely than non-smokers to agree that smoking is harmful to their health. Both smokers and non-smokers were not well informed of the dangers of passive smoke exposure. The majority of smokers were in precontemplation (no interest in quitting within the next 6 months). Fewer than half of residents who smoked reported receiving cessation advice from physicians (40%) or nurses (36%), and no in-house cessation programs were available. These results suggest gaps in knowledge and resources for smoking cessation in this setting and an opportunity for intervention. This study begins to build an evidence base from the residents' perspective that can be used by healthcare providers, administrators, and policy makers in addressing smoking in the nursing home.

Patients with early-stage chronic kidney disease (CKD) must make lifestyle modifications and adhere to treatment regimens to prevent their progression to end-stage kidney disease. The aim of this study was to elicit the perspectives of patients with stage 1-4 CKD about their disease, with a specific focus on their information needs in managing and living with CKD and its sequelae. Patients with CKD stages 1-4 were purposively sampled from three major hospitals in Sydney, Australia to participate in focus groups. Transcripts were thematically analysed. From nine focus groups including 38 participants, six major themes were identified: medical attentiveness (shared decision-making, rapport, indifference and insensitivity); learning self-management (diet and nutrition, barriers to physical activity, medication safety); contextualizing comorbidities (prominence of CKD, contradictory treatment); prognostic uncertainty (hopelessness, fear of disease progression, disbelief regarding diagnosis); motivation and coping mechanisms (engage in research, pro-active management, optimism, feeling normal); and knowledge gaps (practical advice, access to information, comprehension of pathology results and CKD diagnosis, education for general practitioners). Patients capacity to slow the progression of CKD may be limited by their lack of knowledge about the disease, its comorbidities, psychosocial influences and their ability to interact and communicate effectively with their health-care provider. Support from a multidisciplinary care team, combined with provision of comprehensive, accessible and practical educational resources may enhance patients' ability and motivation to access and adhere to therapeutic and lifestyle interventions to retard progression of CKD. © 2014 Asian Pacific Society of Nephrology.

Gender pay gap and employment sector: sources of earnings disparities in the United States, 1970-2010.

Mandel, Hadas; Semyonov, Moshe

2014-10-01

Using data from the IPUMS-USA, the present research focuses on trends in the gender earnings gap in the United States between 1970 and 2010. The major goal of this article is to understand the sources of the convergence in men's and women's earnings in the public and private sectors as well as the stagnation of this trend in the new millennium. For this purpose, we delineate temporal changes in the role played by major sources of the gap. Several components are identified: the portion of the gap attributed to gender differences in human-capital resources; labor supply; sociodemographic attributes; occupational segregation; and the unexplained portion of the gap. The findings reveal a substantial reduction in the gross gender earnings gap in both sectors of the economy. Most of the decline is attributed to the reduction in the unexplained portion of the gap, implying a significant decline in economic discrimination against women. In contrast to discrimination, the role played by human capital and personal attributes in explaining the gender pay gap is relatively small in both sectors. Differences between the two sectors are not only in the size and pace of the reduction but also in the significance of the two major sources of the gap. Working hours have become the most important factor with respect to gender pay inequality in both sectors, although much more dominantly in the private sector. The declining gender segregation may explain the decreased impact of occupations on the gender pay gap in the private sector. In the public sector, by contrast, gender segregation still accounts for a substantial portion of the gap. The findings are discussed in light of the theoretical literature on sources of gender economic inequality and in light of the recent stagnation of the trend.

The increasing prevalence of childhood obesity in Latin America poses a major public health challenge to the region. In response, many countries are implementing obesity prevention programmes aimed at modifying known risk factors. However, the limited scientific evidence inhibits the development and implementation of novel, effective interventions across the region. To address these gaps, the NIH Fogarty International Center convened a workshop of researchers, policymakers, programme implementers and public health advocates who are actively engaged in the region to prevent childhood obesity. Major aims of the meeting were to define the current status of childhood obesity, identify the scientific gaps in our understanding of the epidemic, point out the barriers and opportunities for research and outline a plan for capacity building in the region in the area of childhood obesity. This series of articles reflects the key outcome of the meeting and offers an analysis of the knowledge translation needed for evidence-based policy initiatives, a review of the research agenda and an evaluation of research capacity in the region. The goal of the papers is to inform the development of multidisciplinary and multisector research collaborations, which are essential to the implementation of successful childhood obesity prevention strategies in the region. © 2017 The Authors.

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

Status epilepticus (SE) is a life-threatening condition that can be refractory to initial treatment. Randomized controlled studies to guide treatment choices, especially beyond first-line drugs, are not available. This report summarizes the evidence that guides the management of refractory convulsive SE (RCSE) in children, defines gaps in our clinical knowledge and describes the development and works of the 'pediatric Status Epilepticus Research Group' (pSERG). A literature review was performed to evaluate current gaps in the pediatric SE and RCSE literature. In person and online meetings helped to develop and expand the pSERG network. The care of pediatric RCSE is largely based on extrapolations of limited evidence derived from adult literature and supplemented with case reports and case series in children. No comparative effectiveness trials have been performed in the pediatric population. Gaps in knowledge include risk factors for SE, biomarkers of SE and RCSE, second- and third-line treatment options, and long-term outcome. The care of children with RCSE is based on limited evidence. In order to address these knowledge gaps, the multicenter pSERG was established to facilitate prospective collection, analysis, and sharing of de-identified data and biological specimens from children with RCSE. These data will allow identification of treatment strategies associated with better outcomes and delineate evidence-based interventions to improve the care of children with SE.

BACKGROUND: The underassessment and undertreatment of pain in residents of long-term care (LTC) facilities has been well documented. Gaps in staff knowledge and inaccurate beliefs have been identified as contributors. OBJECTIVES: To investigate the effectiveness of an expert-based continuing education program in pain assessment/management for LTC staff. METHODS: Participants included 131 LTC staff members who were randomly assigned to either an interactive pain education (PE) program, which addressed gaps in knowledge such as medication management, or an interactive control program consisting of general dementia education without a specific clinical focus. Participants attended three sessions, each lasting 3 h, and completed measures of pain-related knowledge and attitudes/beliefs before, immediately after and two weeks following the program. Focus groups were conducted with a subset of participants to gauge perception of the training program and barriers to implementing pain-related strategies. RESULTS: Analysis using ANOVA revealed that PE participants demonstrated larger gains compared with control participants with regard to pain knowledge and pain beliefs. Barriers to implementing pain-related strategies certainly exist. Nonetheless, qualitative analyses demonstrated that PE participants reported that they overcame many of these barriers and used pain management strategies four times more frequently than control participants. CONCLUSIONS: Contrary to previous research, the present study found that the interactive PE program was effective in changing pain beliefs and improving knowledge. Continuing PE in LTC has the potential to address knowledge gaps among front-line LTC providers. PMID:23457681

Khanna, Rahul; Jariwala, Krutika

2012-01-01

In the past few decades, the prevalence of autism has increased tremendously in the United States. The prevalence of autism is now higher than the combined prevalence of juvenile diabetes, pediatric cancer, and pediatric AIDS. As health care professionals with a high visibility in a community, pharmacists are likely to encounter more and more families having a child affected by this disorder. The purpose of this study was to assess pharmacists' awareness and knowledge of autism. The study aimed to assess pharmacists' familiarity with autism symptoms, treatment medications, and community resources devoted to this disorder. Further, pharmacists' knowledge of common myths associated with autism, etiology, prognosis, and treatment were assessed. Using a cross-sectional design, an online survey of pharmacists registered in the state of Mississippi (MS) was conducted, using the Qualtrics software program. Descriptive analysis of study items was conducted. A total of 147 usable responses (5.8%) were received. The results indicated gaps in pharmacists' awareness and knowledge of autism. Approximately, 23% of pharmacists did not know that autism is a developmental disorder, and 32% did not believe that genetics has a major role in autism etiology. More than 18% believed that vaccines can cause autism. Most (>90%) felt that they could benefit from autism continuing education (CE). Policy makers and autism agencies should consider providing educational interventions or CE programs to increase pharmacists' awareness and knowledge of autism. Copyright © 2012 Elsevier Inc.

Innovation strategy management survey of the Chilean biomedical industry. Assessment of windows of opportunities to reduce technological gaps.

PubMed

Bas, Tomas Gabriel; Oliu, Carolina Alejandra

2018-04-01

The convergence of different theories (ie, catch-up effect and windows of opportunities) allows for the interpretation of different "technological innovation gaps" in Chile's biomedical industry. It is common knowledge that Chile has always had an economy almost exclusively based on services, commodities, and mainly in the exploitation of natural resources with low value added. The literature confirms that countries that concentrate their economies on the knowledge, research, development, and commercialization of technology and innovation have a better and more stable growth rate in the medium and long run. The "Asian Tigers" are a good example of this. Analyzing the technological gaps that affect the Chilean biomedical industry, it is possible to find windows of opportunities to catch up. This could allow the country to take its knowledge, skills, and capabilities further, thus enabling Chile to not just depend on its unpredictable natural resources. For the first time, a quantitative diagnosis of the Chilean biomedical industry was made. This study considered the Chilean biomedical industry and its innovation and entrepreneurship environment, taking into account its productive capacities and its potential to make progress in technological innovation and, as a result, dramatically reducing technological gaps through windows of opportunities.

EM-31 RETRIEVAL KNOWLEDGE CENTER MEETING REPORT: MOBILIZE AND DISLODGE TANK WASTE HEELS

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

Fellinger, A.

2010-02-16

The Retrieval Knowledge Center sponsored a meeting in June 2009 to review challenges and gaps to retrieval of tank waste heels. The facilitated meeting was held at the Savannah River Research Campus with personnel broadly representing tank waste retrieval knowledge at Hanford, Savannah River, Idaho, and Oak Ridge. This document captures the results of this meeting. In summary, it was agreed that the challenges to retrieval of tank waste heels fell into two broad categories: (1) mechanical heel waste retrieval methodologies and equipment and (2) understanding and manipulating the heel waste (physical, radiological, and chemical characteristics) to support retrieval optionsmore » and subsequent processing. Recent successes and lessons from deployments of the Sand and Salt Mantis vehicles as well as retrieval of C-Area tanks at Hanford were reviewed. Suggestions to address existing retrieval approaches that utilize a limited set of tools and techniques are included in this report. The meeting found that there had been very little effort to improve or integrate the multiple proven or new techniques and tools available into a menu of available methods for rapid insertion into baselines. It is recommended that focused developmental efforts continue in the two areas underway (low-level mixing evaluation and pumping slurries with large solid materials) and that projects to demonstrate new/improved tools be launched to outfit tank farm operators with the needed tools to complete tank heel retrievals effectively and efficiently. This document describes the results of a meeting held on June 3, 2009 at the Savannah River Site in South Carolina to identify technology gaps and potential technology solutions to retrieving high-level waste (HLW) heels from waste tanks within the complex of sites run by the U. S. Department of Energy (DOE). The meeting brought together personnel with extensive tank waste retrieval knowledge from DOE's four major waste sites - Hanford, Savannah River, Idaho, and Oak Ridge. The meeting was arranged by the Retrieval Knowledge Center (RKC), which is a technology development project sponsored by the Office of Technology Innovation & Development - formerly the Office of Engineering and Technology - within the DOE Office of Environmental Management (EM).« less

The importance of consistent, accurate and unambiguous messages are well documented in oral health promotion literature. Whether the reality of delivering messages in the field fulfils these principle is questionable. This paper explores the perceptions of dental professionals, healthcare professionals and lay community members with regard to key oral health messages in order to highlight any inconsistencies and knowledge gaps between and within groups for disease risk factors. A questionnaire was administered to individuals who belonged to three groups: dental professionals, healthcare professionals and lay community members. The questionnaire established knowledge regarding risk factors for caries, periodontal disease and erosion. Thirty-five (57.4%) of the dental group answered the whole questionnaire correctly, with 22 (27.8%) and 9 (5.1%) of the healthcare and lay community group answering the whole questionnaire correctly, respectively. The question of fluoride levels in children's toothpaste was the main reason for incorrect answers in the dental group. The results of this survey demonstrate a knowledge gradient from dental professionals through to healthcare professionals and then to lay members of the community. The knowledge base observed in the dental group is reflected in the other two groups as would be expected albeit with a significant gap between each group. As expected the dental professionals are generally well informed, but not as well informed as could be expected.

Factors impacting on nurses' transference of theoretical knowledge of holistic care into clinical practice.

PubMed

Henderson, Saras

2002-12-01

Since nurse education moved to universities, a reoccurring concern of health consumers, health administrators, and some practising nurses is that nurses are not able to transfer the theoretical knowledge of holistic care into practice. Much has been written about this concern usually under the heading of the theory-practice gap. A common reason that has been highlighted as the cause of this gap is that the theoretical knowledge that nurses learn in academia is predicated on concepts such as humanism and holistic caring. In contrast, the bureaucratic organisation where nurses provide care tends to be based on management concepts where cost containment and outcome measures are more acceptable. Hence nurses' learned values of holistic caring are pitted against the reality of the practice setting. So what is this practice reality? This paper attempts to provide an insider view of why the theoretical knowledge of holistic care may be difficult to enact in the clinical setting. In-depth taped interviews with nurses and participant observation were conducted in acute care hospitals in Western Australia. The interviews were transcribed verbatim and analysed using the constant comparative method. The findings indicated that utilitarian nursing and role models had impacted on the transference of theoretical knowledge of holistic care into practice. The paper outlines some measures that nurses themselves can undertake to ensure the narrowing of the theory-practice gap in this area.

health professionals in Belgium are confronted with female genital mutilation (FGM). To date, no survey to assess knowledge, attitudes and practices on FGM was conducted among midwives in the Northern region of Belgium. the objective of this study was to assess the knowledge, attitude and practices of Flemish midwives regarding female genital mutilation (FGM). we used a quantitative design, using KAP study (semi-structured questionnaire). labour wards, maternity wards and maternal intensive care units (MIC) in 56 hospitals in Flemish region of Belgium. 820 midwives, actively working in labour wards, maternity wards and maternal intensive care units (MIC). 820 valid questionnaires (40.9%) were returned. More than 15% of the respondents were recently confronted with FGM. They were mostly faced with the psychological and sexual complications caused by FGM. Few respondents were aware of existing guidelines regarding FGM in their hospitals (3.5%). The results also showed that only 20.2% was aware of the exact content of the law. The majority of midwives condemned the harmful traditional practice: FGM was experienced as a form of violence against women or a violation of human rights. Only 25.9% declared that FGM forms a part of their midwifery program. The vast majority of respondents (92.5%) indicated a need for more information on the subject. this study indicated that midwives in Flanders are confronted with FGM and its complications and highlighted the gaps in the knowledge of Flemish midwives regarding FGM. This may interfere with the provision of adequate care and prevention of FGM for the new-born daughter. there is an important need for appropriate training of (student)midwives concerning FGM as well as for the development and dissemination of clear guidelines in Flemish hospitals.

There is compelling evidence for the benefits of regular exercise during pregnancy, and medical practitioners (MPs) can play an important role in changing antenatal health behaviours. The purpose of this study was to assess the knowledge, attitudes and beliefs of South African MPs towards exercise during pregnancy. A convenience sample of ninety-six MPs working in the private health care sector, including General Practitioners (n = 58), Obstetricians/Gynaecologists (n = 33) and other Specialists (n = 5), participated in this cross sectional, descriptive survey study. A 33-item questionnaire was distributed manually at medical practices and via email to an on-line survey tool. Descriptive statistics and frequency tables were calculated for all questions. Chi-squared and Fisher's exact statistical tests were used to determine the differences in response by age, speciality and years of practice (p < 0.05). The majority of practitioners (98%) believe that exercise during pregnancy is beneficial, and were knowledgeable on most of the expected benefits. Seventy-eight percent believed that providing exercise advice is an important part of prenatal care, however only 19% provided informational pamphlets and few (24%) referred to exercise specialists. A large majority (83%) were unaware of the recommended exercise guidelines. Although age and years of practice played no role in this awareness, practitioners who focussed on obstetrics and gynaecology were more likely to be aware of the current guidelines, than those in general practice (p < 0.001). Although the MPs were largely positive towards exercise during pregnancy, their advice did not always align with the current guidelines. Therefore, better dissemination of available research is warranted, to bridge the gap between clinical knowledge and current recommendations for physical activity promotion.

Barbosa, Fabiana G

2014-09-01

Limnoperna fortunei (golden mussel) is a freshwater bivalve native to Southeast Asia, but is becoming an invasive species in several aquatic ecosystems in the world. In this study, a scientometric analysis was performed to identify the patterns, trends and gaps of knowledge for this invasive species. A survey of the published literature was conducted using the database of the Thomson Institute for Scientific Information (ISI). A total of 107 papers were surveyed that were published between 1982 and 2012 in 60 journals. The number of papers on L. fortunei over the years has increased, especially within the last eight years of the study period. Argentina, Brazil, and Japan are the countries that contributed the most papers to the literature on invasive bivalve. The majority of papers were field-observational studies. Among some important gaps that need to be addressed are the relatively small number and/or lack of studies conducted in the native countries and in countries invaded by L. fortunei, the lack of internationally collaborative publications in these countries, as well as a low number of internationally collaborative studies.

Do the adult criminal careers of African Americans fit the “facts”?

2014-01-01

Purpose A major gap in the criminal career research is our understanding of offending among African Americans, especially beyond early adulthood. In light of this gap, this study describes the criminal career patterns of a cohort of African American males and females. Methods This paper uses official criminal history data spanning ages 17 to 52 from the Woodlawn Study, a community cohort of 1,242 urban African American males and females. We use basic descriptive statistics as well as group-based modeling to provide a detailed description of the various dimensions of their adult criminal careers. Results We find cumulative prevalence rates similar to those for African Americans from national probability sample estimates, yet participation in offending extends farther into midlife than expected with a substantial proportion of the cohort still engaged in offending into their 30s. Conclusions The descriptive analyses contribute to the larger body of knowledge regarding the relationship between age and crime and the unfolding of the criminal career for African American males and females. The applicability of existing life course and developmental theories is discussed in light of the findings. PMID:25605979

An overview is presented of the current state of knowledge of the salient aspects of the sources, transport, and alterations of arsenic, beryllium, cadmium, chromium, and nickel. This information is considered vital for a better assessment of the scope of potential human hazard to these ubiquitous toxicants and their compounds. Stress is focused on both natural and industrial activities, particularly on the latter's projected trends. Increasing use patterns per se of most of these metals, as well as aspects of waste disposal and the anticipated increased combustion of fossil fuels for power generation and space heating (particularly in the United States), are major causes of potential health concern. Additionally, attention is drawn to the need for increased research to fill the gaps in our knowledge in these vital areas, all in the hope of permitting a more facile identification and quantification of the potential hazard to exposure to these agents.

This review paper summarizes the existing knowledge on the chemical hazards associated with recycling and other end-of-life treatment options of waste electrical and electronic equipment (e-waste). The hazards arise from the presence of heavy metals (e.g., mercury, cadmium, lead, etc.), flame retardants (e.g., pentabromophenol, polybrominated diphenyl ethers (PBDEs), tetrabromobisphenol-A (TBBPA), etc.) and other potentially harmful substances in e-waste. If improperly managed, the substances may pose significant human and environmental health risks. The review describes the potentially hazardous content of e-waste, examines the existing e-waste management practices and presents scientific data on human exposure to chemicals, workplace and environmental pollution associatedmore » with the three major e-waste management options, i.e., recycling, incineration and landfilling. The existing e-waste management practices and associated hazards are reviewed separately for developed and developing countries. Finally, based on this review, the paper identifies gaps in the existing knowledge and makes some recommendations for future research.« less

Most current content-based image retrieval systems are still incapable of providing users with their desired results. The major difficulty lies in the gap between low-level image features and high-level image semantics. To address the problem, this study reports a framework for effective image retrieval by employing a novel idea of memory learning. It forms a knowledge memory model to store the semantic information by simply accumulating user-provided interactions. A learning strategy is then applied to predict the semantic relationships among images according to the memorized knowledge. Image queries are finally performed based on a seamless combination of low-level features and learned semantics. One important advantage of our framework is its ability to efficiently annotate images and also propagate the keyword annotation from the labeled images to unlabeled images. The presented algorithm has been integrated into a practical image retrieval system. Experiments on a collection of 10,000 general-purpose images demonstrate the effectiveness of the proposed framework.

Recent changes in trend and variability of the main Southern Hemisphere climate modes are driven by a variety of factors, including increasing atmospheric greenhouse gases, changes in tropical sea surface temperature, and stratospheric ozone depletion and recovery. One of the most important implications for climatic change is its effect via climate teleconnections on natural ecosystems, water security, and fire variability in proximity to populated areas, thus threatening human lives and properties. Only sparse and fragmentary knowledge of relationships between teleconnections, lightning strikes, and fire is available during the observed record within the Southern Hemisphere. This constitutes a major knowledge gap for undertaking suitable management and conservation plans. Our analysis of documentary fire records from Mediterranean and temperate regions across the Southern Hemisphere reveals a critical increased strength of climate-fire teleconnections during the onset of the 21st century including a tight coupling between lightning-ignited fire occurrences, the upward trend in the Southern Annular Mode, and rising temperatures across the Southern Hemisphere.

Recognition of ischemic heart disease (IHD) is often delayed or deferred in women. Thus, many at risk for adverse outcomes are not provided specific diagnostic, preventive, and/or treatment strategies. This lack of recognition is related to sex-specific IHD pathophysiology that differs from traditional models using data from men with flow-limiting coronary artery disease (CAD) obstructions. Symptomatic women are less likely to have obstructive CAD than men with similar symptoms, and tend to have coronary microvascular dysfunction, plaque erosion, and thrombus formation. Emerging data document that more extensive, nonobstructive CAD involvement, hypertension, and diabetes are associated with major adverse events similar to those with obstructive CAD. A central emerging paradigm is the concept of nonobstructive CAD as a cause of IHD and related adverse outcomes among women. This position paper summarizes currently available knowledge and gaps in that knowledge, and recommends management options that could be useful until additional evidence emerges. PMID:26493665

Unsafe abortion is a major Public health problem in developing countries, where women make several unsafe attempts at termination of the unintended pregnancy before turning to health services. Community health workers can act as a bridge between the community and their health facilities and can use Emergency Contraceptive Pills to significantly reduce the mortality and morbidity related to unsafe abortions. This study explores the knowledge, attitudes and practices of the Lady Health Supervisor of the National Program for Family Planning, district Rawalpindi, regarding emergency contraception pills. The cross sectional survey was conducted during the monthly meeting of Lady Health Supervisors. Self administered, anonymous and voluntary questionnaire consisting of 17 items, regarding demographic profile, awareness, knowledge, attitudes and practices, was used. Insufficient knowledge, high misinformation and strongly negative attitudes were revealed. More than half did not know that emergency contraceptive pills do not cause abortion. About four fifths believed that emergency contraceptive pills will lead to 'evil' practices in society. More than four fifths recognized that the clients of National Program for Family Planning need emergency contraceptive pills. The attitudes were significantly associated with knowledge (P=0.034, Fisher's Exact Test). The awareness of emergency contraceptive pills is high. Serious gaps in knowledge have been identified. There is a clear recognition of the need of emergency contraceptive pills for the clients of National Program for Family Planning. However, any strategy to introduce emergency contraceptive pills must cater for the misplaced beliefs of the work force.

Purpose Current guidelines recommend that patients with CHD receive age-appropriate counselling on reproduction, pregnancy, and risk of heredity. Our aim was to examine patient knowledge of reproductive health and explore the association between patient knowledge of CHD transmission risk and earlier physician counselling in adults with CHD. We performed a cross-sectional survey of patients with CHD aged 18 years and older in a paediatric hospital. Of the 100 patients who completed the questionnaire, most did not report counselling on heredity (66%) or contraception (71%). Of the 54 women, 25 (46%) identified their contraceptive options correctly; 42 (78%) women were classified as being at significantly increased risk for an adverse outcome during pregnancy, and of these 20 (48%) identified this risk correctly. Of all patients surveyed, 72% did not know that having CHD placed them at increased risk for having a child with CHD. On multivariate analysis, factors associated with correct knowledge about risk of recurrence were correct identification of CHD diagnosis (p=0.04) and patient-reported counselling (p=0.001). Knowledge about heredity, pregnancy risk, and contraceptive options is inadequate among adults with CHD followed-up in a paediatric subspecialty clinic. The majority of patients did not report a history of counselling about reproductive health. There is a strong correlation between history of counselling by the patient's cardiologist and correct knowledge about recurrence risk, suggesting that effective reproductive counselling can positively impact this knowledge gap.

Sodium intake is high in Lebanon, a country of the Middle East region where rates of cardiovascular diseases are amongst the highest in the world. This study examines salt-related knowledge, attitude and self-reported behaviors amongst adult Lebanese consumers and investigates the association of socio-demographic factors, knowledge and attitudes with salt-related behaviors. Using a multicomponent questionnaire, a cross-sectional study was conducted in nine supermarkets in Beirut, based on systematic random sampling (n = 442). Factors associated with salt-related behaviors were examined by multivariate regression analysis. Specific knowledge and attitude gaps were documented with only 22.6% of participants identifying processed foods as the main source of salt, 55.6% discerning the relationship between salt and sodium, 32.4% recognizing the daily limit of salt intake and 44.7% reporting being concerned about the amount of salt in their diet. The majority of participants reported behavioral practices that increase salt intake with only 38.3% checking for salt label content, 43.7% reporting that their food purchases are influenced by salt content and 38.6% trying to buy low-salt foods. Knowledge, attitudes and older age were found to significantly predict salt-related behaviors. Findings offer valuable insight on salt-related knowledge, attitude and behaviors in a sample of Lebanese consumers and provide key information that could spur the development of evidence-based salt-reduction interventions specific to the Middle East.

Bissonette, G B; Roesch, M R

2016-01-01

The past two decades have seen an explosion in our understanding of the origin and development of the midbrain dopamine system. Much of this work has been focused on the aspects of dopamine neuron development related to the onset of movement disorders such as Parkinson's disease, with the intent of hopefully delaying, preventing or fixing symptoms. While midbrain dopamine degeneration is a major focus for treatment and research, many other human disorders are impacted by abnormal dopamine, including drug addiction, autism and schizophrenia. Understanding dopamine neuron ontogeny and how dopamine connections and circuitry develops may provide us with key insights into potentially important avenues of research for other dopamine-related disorders. This review will provide a brief overview of the major molecular and genetic players throughout the development of midbrain dopamine neurons and what we know about the behavioral- and disease-related implications associated with perturbations to midbrain dopamine neuron development. We intend to combine the knowledge of two broad fields of neuroscience, both developmental and behavioral, with the intent on fostering greater discussion between branches of neuroscience in the service of addressing complex cognitive questions from a developmental perspective and identifying important gaps in our knowledge for future study. © 2015 John Wiley & Sons Ltd and International Behavioural and Neural Genetics Society.

p38 Mitogen Activated Protein Kinase (MAPK): A New Therapeutic Target for Reducing the Risk of Adverse Pregnancy Outcomes

Menon, Ramkumar; Papaconstantinou, John

2016-01-01

Introduction Spontaneous preterm birth (PTB) and preterm premature rupture of the membranes (pPROM) remain as a major clinical and therapeutic problem for intervention and management. Current strategies, based on our knowledge of pathways of preterm labor, have only been effective, in part, due to major gaps in our existing knowledge of risks and risk specific pathways. Areas covered Recent literature has identified physiologic aging of fetal tissues as a potential mechanistic feature of normal parturition. This process is affected by telomere dependent and p38 mitogen activated protein kinase (MAPK) induced senescence activation. Pregnancy associated risk factors can cause pathologic activation of this pathway that can cause oxidative stress induced p38 MAPK activation leading to senescence and premature aging of fetal tissues. Premature aging is associated with sterile inflammation capable of triggering preterm labor or preterm premature rupture of membranes. Preterm activation of p38MAPK can be considered as a key contributor to adverse pregnancies. Expert Opinion This review considers p38MAPK activation as a potential target for therapeutic interventions to prevent adverse pregnancy outcomes mediated by stress factors. In this review, we propose multiple strategies to prevent p38MAPK activation and its functional effects. PMID:27459026

2016-10-01

Maternal depression, a non-psychotic depressive episode of mild to major severity, is one of the major contributors of pregnancy-related morbidity and mortality. Maternal depression (antepartum or post partum) has been linked to negative health-related behaviours and adverse outcomes, including psychological and developmental disturbances in infants, children, and adolescents. Despite its enormous burden, maternal depression in low-income and middle-income countries remains under-recognised and undertreated. In this Series paper, we systematically review studies that focus on the epidemiology of perinatal depression (ie, during antepartum and post-partum periods) among women residing in low-income and middle-income countries. We also summarise evidence for the association of perinatal depression with infant and childhood outcomes. This review is intended to summarise findings from the existing literature, identify important knowledge gaps, and set the research agenda for creating new generalisable knowledge pertinent to increasing our understanding of the prevalence, determinants, and infant and childhood health outcomes associated with perinatal depression. This review is also intended to set the stage for subsequent work aimed at reinforcing and accelerating investments toward providing services to manage maternal depression in low-income and middle-income countries.

2014-01-01

With the vast amount of immunological data available, immunology research is entering the big data era. These data vary in granularity, quality, and complexity and are stored in various formats, including publications, technical reports, and databases. The challenge is to make the transition from data to actionable knowledge and wisdom and bridge the knowledge gap and application gap. We report a knowledge-based approach based on a framework called KB-builder that facilitates data mining by enabling fast development and deployment of web-accessible immunological data knowledge warehouses. Immunological knowledge discovery relies heavily on both the availability of accurate, up-to-date, and well-organized data and the proper analytics tools. We propose the use of knowledge-based approaches by developing knowledgebases combining well-annotated data with specialized analytical tools and integrating them into analytical workflow. A set of well-defined workflow types with rich summarization and visualization capacity facilitates the transformation from data to critical information and knowledge. By using KB-builder, we enabled streamlining of normally time-consuming processes of database development. The knowledgebases built using KB-builder will speed up rational vaccine design by providing accurate and well-annotated data coupled with tailored computational analysis tools and workflow.

Background Primary open-angle glaucoma (POAG) is one of the most common causes of irreversible blindness. A possible association between POAG and non-communicable diseases such as hypertension and diabetes suggests that the incidence of POAG may increase. People with POAG in Nepal usually present late to hospital and have poor knowledge of glaucoma. Objectives Anticipating a knowledge gap regarding these diseases, this study aimed to explore the knowledge of POAG, hypertension, and diabetes in the community and barriers to health care. Design We conducted this qualitative study in the Jhaukhel-Duwakot Health Demographic Surveillance Site (JD-HDSS), a peri-urban community near Kathmandu, a capital city of Nepal. To study how disease influences knowledge, we conducted focus group discussions separately for men and women with and without pre-existing POAG, hypertension, and diabetes. Data were analyzed using the framework analysis approach. Results Although people suffering from POAG, hypertension, and/or diabetes exhibited adequate knowledge of hypertension and diabetes, they lacked in-depth knowledge of POAG. People believed mostly in internal health locus of control. Perception of disease consequences and impact of disease on daily life was influenced by pre-existing POAG, hypertension, and/or diabetes but only in men. Gender disparity was observed regarding health literacy, health perception, and health barriers, which put women in a more difficult situation to tackle their health. We also revealed a gap between knowledge, attitude, and practice of health among women and healthy men. Conclusion Although people in JD-HDSS exhibited adequate knowledge regarding hypertension and diabetes, they lacked in-depth knowledge about POAG. This study demonstrated gender difference in health literacy and access to health care, making women more vulnerable towards disease. We also demonstrated a gap between knowledge, attitude, and practice of health. However, tailored health literacy programs may bring changes in the health status in the community. PMID:25361727

Objective The breadth and depth of patient safety/quality improvement (PS/QI) research dedicated to otolaryngology-head and neck surgery (OHNS) education remains unknown. This systematic review aims to define this scope and to identify knowledge gaps as well as potential areas of future study to improved PS/QI education and training in OHNS. Data Sources A computerized Ovid/Medline database search was conducted (January 1, 1965, to May 15, 2015). Similar computerized searches were conducted using Cochrane Database, PubMed, and Google Scholar. Review Methods The study protocol was developed a priori using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Articles were classified by year, subspecialty, Institute of Medicine (IOM) Crossing the Chasm categories, and World Health Organization (WHO) subclass. Results Computerized searches yielded 8743 eligible articles, 267 (3.4%) of which met otolaryngology PS/QI inclusion criteria; 51 (19%) were dedicated to resident/fellow education and training. Simulation studies (39%) and performance/competency evaluation (23.5%) were the most common focus. Most projects involved general otolaryngology (47%), rhinology (18%), and otology (16%). Classification by the IOM included effective care (45%), safety/effective care (41%), and effective and efficient care (7.8%). Most research fell into the WHO category of "identifying solutions" (61%). Conclusion Nineteen percent of OHNS PS/QI articles are dedicated to education, the majority of which are simulation and focus on effective care. Knowledges gaps for future research include facial plastics PS/QI and the WHO category of "studies translating evidence into safer care."

Public Awareness and Practice of Responsible Gambling in Macao.

2018-01-30

Responsible gambling (RG) is a relatively new concept to the Macao gambling industry. Although recent studies reported a heightened public awareness of RG, the prevalence of disordered gambling is still high. This discrepancy may suggest an existing gap between RG awareness and gambling practices, pinpointing aspects that need to be improved by different RG stakeholders. The gap may be attributable to people's limited knowledge toward practices favoring RG. To explore means for enhancing the RG campaign, we studied Macao residents' interpretation and adoption of RG practices. In Study 1, a random community sample was collected to assess the extent to which common RG practices were adopted. Results suggested that there was a fair proportion of gamblers not adhering to them and gambling disorder tendency was related to the adoption of RG practices. It implied a successful promotion of RG practices may reduce gambling problems. In Study 2, focus group discussions were conducted to explore how RG was conceptualized. Twenty-five participants (including 11 casino employees) took part in four focus group interviews. All participants were aware of RG but their knowledge of RG practices was limited. Very few of them were able to identify major practices such as putting constraints on gambling amount and time and the application for self-exclusion. We argue that future RG promotion needs to be more specific and behavior-oriented and it should also address various procedural concerns on how RG practices can be implemented.

Biology and impacts of Pacific Islands invasive species. 14. Sus scrofa the feral pig (Artiodactyla: Suidae)

Wehr, Nathaniel H.; Hess, Steven C.; Litton, Creighton M.

2018-01-01

Feral pigs (Sus scrofa L.) are perhaps the most abundant, widespread, and economically significant large introduced vertebrate across the Pacific island region. Unlike many other nonnative invasive species, feral pigs have both cultural and recreational importance in the region, complicating their management. Today, Pacific island feral pigs are a mixture of several strains of domestic swine, Asiatic wild boar, and European wild boar. Due to their generalist diet and rooting behavior, feral pigs alter soils and watersheds and negatively impact native and nonnative flora and fauna. As a result, feral pigs have played a role in the extinction of several species of plants and animals on Pacific islands and have negative effects on both ecotourism and agricultural industries in the region. Despite numerous published studies on feral pigs in the Pacific island region, of which the majority include systematic analyses of original empirical data, some fundamental aspects of feral pig ecology remain poorly characterized, at least partly due to the remote and inaccessible environments that they often inhabit. To address these knowledge gaps, effort should be made to integrate research conducted outside the Pacific island region into local management strategies. This review summarizes the origins, history, ecology, environmental effects, and current management of feral pigs in the Pacific island region; integrates regional scientific findings with those of other insular and continental systems; and identifies current knowledge gaps requiring further research to inform the ecology and management of this impactful invasive species.

Gap Size Uncertainty Quantification in Advanced Gas Reactor TRISO Fuel Irradiation Experiments

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

Pham, Binh T.; Einerson, Jeffrey J.; Hawkes, Grant L.

The Advanced Gas Reactor (AGR)-3/4 experiment is the combination of the third and fourth tests conducted within the tristructural isotropic fuel development and qualification research program. The AGR-3/4 test consists of twelve independent capsules containing a fuel stack in the center surrounded by three graphite cylinders and shrouded by a stainless steel shell. This capsule design enables temperature control of both the fuel and the graphite rings by varying the neon/helium gas mixture flowing through the four resulting gaps. Knowledge of fuel and graphite temperatures is crucial for establishing the functional relationship between fission product release and irradiation thermal conditions.more » These temperatures are predicted for each capsule using the commercial finite-element heat transfer code ABAQUS. Uncertainty quantification reveals that the gap size uncertainties are among the dominant factors contributing to predicted temperature uncertainty due to high input sensitivity and uncertainty. Gap size uncertainty originates from the fact that all gap sizes vary with time due to dimensional changes of the fuel compacts and three graphite rings caused by extended exposure to high temperatures and fast neutron irradiation. Gap sizes are estimated using as-fabricated dimensional measurements at the start of irradiation and post irradiation examination dimensional measurements at the end of irradiation. Uncertainties in these measurements provide a basis for quantifying gap size uncertainty. However, lack of gap size measurements during irradiation and lack of knowledge about the dimension change rates lead to gap size modeling assumptions, which could increase gap size uncertainty. In addition, the dimensional measurements are performed at room temperature, and must be corrected to account for thermal expansion of the materials at high irradiation temperatures. Uncertainty in the thermal expansion coefficients for the graphite materials used in the AGR-3/4 capsules also increases gap size uncertainty. This study focuses on analysis of modeling assumptions and uncertainty sources to evaluate their impacts on the gap size uncertainty.« less

Since its emergence in the 1990s, White Spot Disease (WSD) has had major economic and societal impact in the crustacean aquaculture sector. Over the years shrimp farming alone has experienced billion dollar losses through WSD. The disease is caused by the White Spot Syndrome Virus (WSSV), a large dsDNA virus and the only member of the Nimaviridae family. Susceptibility to WSSV in a wide range of crustacean hosts makes it a major risk factor in the translocation of live animals and in commodity products. Currently there are no effective treatments for this disease. Understanding the molecular basis of disease processes has contributed significantly to the treatment of many human and animal pathogens, and with a similar aim considerable efforts have been directed towards understanding host–pathogen molecular interactions for WSD. Work on the molecular mechanisms of pathogenesis in aquatic crustaceans has been restricted by a lack of sequenced and annotated genomes for host species. Nevertheless, some of the key host–pathogen interactions have been established: between viral envelope proteins and host cell receptors at initiation of infection, involvement of various immune system pathways in response to WSSV, and the roles of various host and virus miRNAs in mitigation or progression of disease. Despite these advances, many fundamental knowledge gaps remain; for example, the roles of the majority of WSSV proteins are still unknown. In this review we assess current knowledge of how WSSV infects and replicates in its host, and critique strategies for WSD treatment. PMID:26797629

To explore the evidence and knowledge gaps in sentinel node biopsy (SNB) in prostate cancer through a consensus panel of experts. A two-round Delphi survey among experts was followed by a consensus panel meeting of 16 experts in February 2016. Agreement voting was performed using the research and development project/University of California, Los Angeles Appropriateness Methodology on 150 statements in nine domains. The disagreement index based on the interpercentile range, adjusted for symmetry score, was used to assess consensus and non-consensus among panel members. Consensus was obtained on 91 of 150 statements (61%). The main outcomes were: (1) the results from an extended lymph node dissection (eLND) are still considered the 'gold standard', and sentinel node (SN) detection should be combined with eLND, at least in patients with intermediate- and high-risk prostate cancer; (2) the role of SN detection in low-risk prostate cancer is unclear; and (3) future studies should contain oncological endpoints as number of positive nodes outside the eLND template, false-negative and false-positive SN procedures, and recurrence-free survival. A high rate of consensus was obtained regarding outcome measures of future clinical trials on SNB (89%). Consensus on tracer technology was only obtained in 47% of statements, reflecting a need for further research and standardization in this area. The low-level evidence in the available literature and the composition of mainly SNB users in the panel constitute the major limitations of the study. Consensus on a majority of elementary statements on SN detection in prostate cancer was obtained.; therefore, the results from this consensus report will provide a basis for the design of further studies in the field. A group of experts identified evidence and knowledge gaps on SN detection in prostate cancer and its application in daily practice. Information from the consensus statements can be used to direct further studies. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

An Introduction to Atmospheric Radiation: Review for the Bulletin of AMS

NASA Technical Reports Server (NTRS)

Marshak, Alexander

2003-01-01

Whether you like a certain geophysical book or not, largely depends on your background. The field of radiative transfer and atmospheric radiation, in particular, combines people with a wide range of mathematical skills: from theoretical astrophysicists and nuclear physicists to meteorologists and ecologists. There is always a delicate balance between physical explanations and their mathematical interpretations. This balance is very personal and is based on your background. I came to the field of atmospheric radiative transfer as a mathematician with little knowledge of atmospheric physics. After being in the field for more than a decade, I still have gaps in my atmospheric science education. Thus I assess a radiative transfer book fi-om two main criteria: how well does it describe the material that is familiar to me (the radiative transfer equation and its numerical solutions) and how well does it help me to fill the gaps in my personal knowledge. So I present this review fi-om the perspective of a former mathematician working in the field of atmospheric radiation. . After being asked to review the book, my first intention was to compare the new edition with the previous one (Liou, 1980). In doing so, you can clearly follow the progress made in the field of atmospheric radiation over the past two decades. If there are few changes (as in Fundamental Radiative Transfer) or no changes at all (as in the Maxwell s equations), then the field has not seen much development. To the contrary, many differences between the two editions illustrate areas of major progress in the field, such as evidenced in Thermal Ineared Radiative Transfer and even in the creations of completely new fields like Three-Dimensional Radiative Transfer or Light Scattering by Nonspherical Particles. Obviously, the major changes happened not in the theory, which is at least half a century old, but in data quality and completely new measurements (mostly due to new satellite data) with higher accuracy and more reliability. The new edition illustrates this progress well.

The static and dynamic mechanical behaviour of cellular materials can be designed by the architecture of the underlying unit cell. In this paper, the phononic band structure of 2D and 3D cellular structures is investigated. It is shown how the geometry of the unit cell influences the band structure and eventually leads to full band gaps. The mechanism leading to full band gaps is elucidated. Based on this knowledge, a 3D cellular structure with a broad full band gap is identified. Furthermore, the dependence of the width of the gap on the geometry parameters of the unit cell is presented. PMID:28793713

The Saint Elias, Alaska, earthquake (magnitude 7.7) of 28 February 1979 is the first major earthquake since 1900 to occur along the complex Pacific-North American plate boundary between Yakutat Bay and Prince William Sound. This event involved complex rupture on a shallow, low-angle, north-dipping fault beneath the Chugach and Saint Elias Mountains. The plate boundary between Yakutat Bay and Prince William Sound had been identified as a seismic gap, an area devoid of major earthquakes during the last few decades, and was thought to be a likely site for a future major earthquake. Since the Saint Elias earthquake fills onlymore » the eastern quarter of the gap, the remainder of the gap to the west is a prime area for the study of precursory and coseismic phenomena associated with large earthquakes. 1 figure, 1 table.« less

Background and Objectives: Students in relevant health-care academic programs are the future professionals who should play an active role in increasing community awareness regarding chronic diseases such as osteoporosis. This research aimed to evaluate the knowledge of osteoporosis, one of the growing health-care burdens in Malaysia, among students belong to three different health occupations programs in a Malaysian University. Methods: A cross-sectional study design was conducted to assess the level of knowledge on osteoporosis and to explore the potential association between the study program and osteoporosis-related knowledge among medicine, pharmacy, and allied health sciences students in a Malaysian University. A total of 348 students were approached. The data were collected using validated revised Osteoporosis Knowledge Test questionnaire. Results: The results showed variability in knowledge score between students belonging to different study programs. allied health sciences students have the highest overall total score (median = 20) and nutrition score (median = 16), but for exercise score, both students in allied health sciences and medicine programs shared a similar median score (median = 11.5). More than half of the respondents showed adequate knowledge on osteoporosis. The students from allied health sciences exhibited more knowledge on osteoporosis compared to students in other study programs. Among the Kulliyyah of Pharmacy respondents, the majority did not manage to answer correctly on the whole scale. This was evident by total percentage of 69.91% of the respondents scored below than median score. Conclusion: There is a considerable gap of knowledge regarding osteoporosis among students in various health occupations academic programs. Pharmacy students particularly need focused learning related to exercise and nutrition in preventing osteoporosis during their academic program. PMID:28717334

The World Health Organization global strategy of promoting oral health have shown vast improvements in developed countries but the scenario is glum among underprivileged communities due to lacunae in implementation of these promotional programs. Manipur, a North Eastern state in India, is one such marginalized area. The study aimed to evaluate Knowledge, Attitude and Practice (KAP) towards oral health in 15-18 year adolescents residing in Manipur together with the association of these variables to sociodemographic factors. This cross-sectional study included 810 healthy adolescents drawn from various primary health care centers spanning in all the nine districts of Manipur. A closed ended questionnaire for the purpose of collecting data was used in the survey. Of the total participants 90.9% had high knowledge, 79.8% had favorable attitude and 70.4% had adequate practice towards oral health. Education of the parents and respondents was the only factor significantly associated with all three variables, knowledge, attitude and practice. Significant and positive linear correlation between knowledge-attitude (r=0.369, p<0.01) knowledge-practice (r=0.405, p<0.01) and attitude-practice (r =0.353, p<0.01), were observed. An overwhelming majority of the respondents had high knowledge, favorable attitude and sound practice with respect to oral health. A positive linear correlation exists between the knowledge, attitude and practice. Evidence based reinforcement programs should be introduced to further reduce the gap between knowledge, attitude and practice. The study will also serve as a reference value for use in future evaluation to help measure the effectiveness of the planned activities. Future research needs to focus on establishing the dental caries prevalence and oral hygiene status of Manipuri youth.

Nutrition knowledge is believed to influence nutritional intake, which in turn influences performance in elite athletes. There is currently no published data on the nutrition knowledge of elite Australian Football (AF) players. The purpose of this study was to gain insight into the current level of general and sports nutrition knowledge in elite male AF athletes. Forty six elite male AF players (23.5 ± 2.8 years) answered 123 questions relating to five areas of nutrition knowledge: dietary recommendations, sources of nutrients, choosing everyday foods, alcohol and sports nutrition. Demographic details and perceptions of nutrition knowledge were collected for all participants. The mean nutrition knowledge score was 74.4 ± 10.9 (60.5%). The highest score was obtained in sports nutrition section (17.9 ± 3.0, 61.7%). The dietitian was selected as the first source of information by 98% of athletes, with club trainer and teammates as second choice for 45.7% and 23.9% of athletes, respectively. The majority of athletes correctly answered questions regarding recommendations to increase fruit and vegetable intake and decrease fat intake (95.6%, 91.1% and 93.3% correct respectively). While 80% of the athletes were aware fat intake should predominately be made up of unsaturated fat, they were less able to identify food sources of unsaturated fats (35.6% and 24.4% correct for statements regarding monounsaturated and polyunsaturated fats, respectively). Broad nutrition messages and recommendations appear to be well understood; however, gaps in nutrition knowledge are evident. A better understanding of nutrition knowledge in athletes will allow nutrition education interventions to target areas in need of improvement.

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.

CDS, UX, and System Redesign - Promising Techniques and Tools to Bridge the Evidence Gap.

PubMed

McGinn, Thomas

2015-01-01

In this special issue of eGEMs, we explore the struggles related to bringing evidence into day-to-day practice, what I define as the "evidence gap." We are all aware of high quality evidence in the form of guidelines, randomized clinical trials for treatments and diagnostic tests, and clinical prediction rules, which are all readily available online. We also know that electronic health records (EHRs) are now ubiquitous in health care and in most practices across the country. How we marry this high quality evidence and the practice of medicine through effective decision support is a major challenge. All of the articles in this issue explore, in some fashion, CDS systems and how we can best bring providers and their work environment to the evidence. We are at the very early stages of the science of usability. Much more research and funding is needed in this area if we hope to improve the dissemination and implementation of evidence in practice. While the featured examples, techniques, and tools in the special issue are a promising start to improving usability and CDS, many of the papers highlight current gaps in knowledge and a great need for generalizable approaches. The great promise is for "learning" approaches to generate new evidence and to integrate this evidence in reliable, patient-centered ways at scale using new technology. Closing the evidence gap is a real possibility, but only if the community works together to innovate and invest in research on the best ways to disseminate, communicate, and implement evidence in practice.

Why We Don't Collaborate in Response to Climate Change: The Knowledge Deficit, Co-Production, and the Future of the IPCC.

Scientific knowledge production is based on recognizing and filling knowledge deficits or 'gaps' in understanding, but for climate adaptation and mitigation, the applicability of this approach is questionable. The Intergovernmental Panel on Climate Change (IPCC) mandate is an example of this type of 'gap filling,' in which the elimination of uncertainties is presumed to enable rational decision making for individuals and rational governance for societies. Presumed knowledge deficits, though, are unsuited to controversial problems with social, cultural, and economic dimensions; likewise, communication to educate is an ineffective means of inciting behavioural change. An alternative is needed, particularly given the economic, social, and political scale that action on climate change requires. We review the 'deficit-education framing' and show how it maintains a wedge between those affected and those whose knowledge is required. We then review co-production to show how natural and social scientists, as well as the IPCC, might more effectively proceed.

Antibiotic resistance is an important problem that requires continued patient education and important prescribing stewardship. Dermatologists prescribe the most antibiotics per provider in comparison to other specialties and have an important role to play in the campaign of mindful prescribing. Data on the dermatology patients' knowledge and perception regarding antibiotic resistance is lacking and could play a role in providers' continuation of medications. We conducted a single institution survey of 512 dermatology clinic patients to understand patient's knowledge and potential gaps. Overall, our results demonstrated an overall higher level of knowledge than expected, there were still several knowledge gaps identified. Ninety-one percent of respondents were aware of the term 'antibiotic resistance'. However, 65% of participants believed that a short course of antibiotics could not cause resistance. While our patients have awareness of antibiotic resistance, it is imperative to continue to assess patients' knowledge about antibiotic resistance and provide education whenever possible in order to continue to practice antibiotic stewardship.

The continued expansion and intensification of agriculture are key drivers of global environmental change. Meeting a doubling of food demand in the next half-century will further induce environmental change, requiring either large cropland expansion into carbon- and biodiversity-rich tropical forests or increasing yields on existing croplands. Closing the “yield gaps” between the most and least productive farmers on current agricultural lands is a necessary and major step towards preserving natural ecosystems and meeting future food demand. Here we use global climate, soils, and cropland datasets to quantify yield gaps for major crops using equal-area climate analogs. Consistent with previous studies, we find large yield gaps for many crops in Eastern Europe, tropical Africa, and parts of Mexico. To analyze the drivers of yield gaps, we collected sub-national agricultural management data and built a global dataset of fertilizer application rates for over 160 crops. We constructed empirical crop yield models for each climate analog using the global management information for 17 major crops. We find that our climate-specific models explain a substantial amount of the global variation in yields. These models could be widely applied to identify management changes needed to close yield gaps, analyze the environmental impacts of agricultural intensification, and identify climate change adaptation techniques.

Healthcare workers who have received disaster preparedness education are more likely to report a greater understanding of disaster preparedness. However, research indicates that current nursing curricula do not adequately prepare nurses to respond to disasters. This is the first study to assess Asia-Pacific nurses' perceptions about their level of disaster knowledge, skills, and preparedness. A cross-sectional survey was conducted with 757 hospital and community nurses in seven Asia-Pacific countries. Data were collected using the modified Disaster Preparedness Evaluation Tool. Participants were found to have overall low-to-moderate levels of disaster knowledge, skills and preparedness, wherein important gaps were identified. A majority of the variance in disaster preparedness scores was located at the level of the individual respondent, not linked to countries or institutions. Multilevel random effects modelling identified disaster experience and education as significant factors of positive perceptions of disaster knowledge, skills, and management. The first step toward disaster preparedness is to ensure frontline health workers are able to respond effectively to disaster events. The outcomes of this study have important policy and education implications. © 2015 Wiley Publishing Asia Pty Ltd.

In South Africa, HPV vaccination programme has been incorporated recently in the school health system. Since doctors are the most trusted people regarding health issues in general, their knowledge and attitudes regarding HPV infections and vaccination are very important for HPV vaccine program nationally. The objective of this study was to investigate factors contributing to recommendation of HPV vaccines to the patients. This was a quantitative cross-sectional study conducted among 320 doctors, using a self-administered anonymous questionnaire. All the doctors were aware of HPV and knew that HPV is transmitted sexually. Their overall level of knowledge regarding HPV infections and HPV vaccine was poor. But the majority intended to prescribe the vaccine to their patients. It was found that doctors who knew that HPV 6 and 11 are responsible for >90% of anogenital warts, their patients would comply with the counselling regarding HPV vaccination, and received sufficient information about HPV vaccination were 5.68, 4.91 and 4.46 times respectively more likely to recommend HPV vaccination to their patients, compared to their counterparts (p<0.05). There was a knowledge gap regarding HPV infection and HPV vaccine among the doctors.

Convincing evidence has accumulated to show that both pre- and postnatal nutrition preprogram long-term health, well-being, and performance until adulthood and old age. There is a very large potential in the application of this knowledge to promote public health. One of the prerequisites for translational application is to strengthen the scientific evidence. More extensive knowledge is needed (eg, on effect sizes of early life programming in contemporary populations, on specific nutritional exposures, on sensitive time periods in early life, on precise underlying mechanisms, and on potential effect differences in subgroups characterized by, eg, genetic predisposition or sex). Future programming research should aim at filling the existing gaps in scientific knowledge, consider the entire lifespan, address socioeconomic issues, and foster innovation. Research should aim at results suitable for translational application (eg, by leading to health-promoting policies and evidence-based dietary recommendations in the perinatal period). International collaboration and a close research partnership of academia, industry, and small and medium enterprises may strengthen research and innovative potential enhancing the likelihood of translational application. The scientific know-how and methodology available today allow us to take major steps forward in the near future; hence, research on nutritional programming deserves high priority.

Can Knowledge Deficit Explain Societal Perception of Climate Change Risk?

Climate change literacy efforts have had a rough journey in the past decade. Although scientists have become increasingly convinced about anthropological climate change, change in public opinion has been underwhelming. The unexplained gap between scientific consensus and public opinion has made this topic an important research area in the realm of public understanding of science. Recent research on climate change risk perception (CCRP) has advanced an intriguing hypothesis, namely, cultural cognition thesis (CCT), which posits that the public has adequate knowledge to understand climate change science but people tend to use this knowledge solely to promote their culturally motivated view-point of climate change. This talk provides evidence to demonstrate that despite culture playing a significant role in influencing CCRP, knowledge deficiency remains a persistent problem in our society and contributes to the aforementioned gap. However, such deficits can remain undiagnosed due to limitations of survey design.

Defining food literacy: A scoping review.

The term "food literacy" describes the idea of proficiency in food related skills and knowledge. This prevalent term is broadly applied, although its core elements vary from initiative to initiative. In light of its ubiquitous use-but varying definitions-this article establishes the scope of food literacy research by identifying all articles that define 'food literacy', analysing its key conceptualizations, and reporting outcomes/measures of this concept. A scoping review was conducted to identify all articles (academic and grey literature) using the term "food literacy". Databases included Medline, Pubmed, Embase, CAB Abstracts, CINAHL, Scopus, JSTOR, and Web of Science, and Google Scholar. Of 1049 abstracts, 67 studies were included. From these, data was extracted on country of origin, study type (methodological approach), primary target population, and the primary outcomes relating to food literacy. The majority of definitions of food literacy emphasize the acquisition of critical knowledge (information and understanding) (55%) over functional knowledge (skills, abilities and choices) (8%), although some incorporate both (37%). Thematic analysis of 38 novel definitions of food literacy reveals the prevalence of six themes: skills and behaviours, food/health choices, culture, knowledge, emotions, and food systems. Study outcomes largely focus on knowledge generating measures, with very few focusing on health related outcome measures. Current definitions of food literacy incorporate components of six key themes or domains and attributes of both critical and functional knowledge. Despite this broad definition of the term, most studies aiming to improve food literacy focus on knowledge related outcomes. Few articles address health outcomes, leaving an important gap (and opportunity) for future research in this field. Copyright © 2017 Elsevier Ltd. All rights reserved.

Various studies have reported poor awareness and knowledge of dentistry in the Nigerian population. There is, however, paucity of information assessing the knowledge and awareness of medical doctors/students and nurses about dentistry. The present study is aimed at determining the knowledge and awareness of medical doctors/students and nurses about dentistry. Self-administered questionnaires were randomly distributed among medical doctors/students, and nurses of Obafemi Awolowo Teaching Hospitals' Complex, Ile-Ife, Nigeria. Information collected using the questionnaire included participants' biodata, questions evaluating dental awareness, knowledge of systemic and oral health connections as well as referral practices. The data analysis was done with STATA version 11 software. A total of 300 questionnaires were randomly distributed among doctors/students and nurses, 206 were returned (response rate of 69%). Of the returned questionnaires, 129(63%) were males and 77(37%) were females. There were 42 medical doctors, 49 nurses and 115 medical students. The mean age of the participants was 26.7 years (SD 5.2). Majority (99.5%) was aware of dental profession, but 92% had never referred patients for dental consultation. One third (31%) of medical doctors believed that Ludwig angina was a cardiac disease. A large proportion of the respondents (61%) see no need for routine dental visit while 27% would want to visit the dentist only when they had a dental complaint. Although a large percentage of the participants claimed to be aware of dentistry, our findings revealed low level of knowledge and attitude to Dentistry. Efforts should be made towards closing this knowledge gap to achieve efficient oral health.

Cardiovascular disease is the number one cause of death worldwide. However, there is not enough data exploring student nurses' understanding, knowledge, and awareness of cardiovascular disease. To investigate knowledge of cardiovascular disease and its risk factors among undergraduate nursing students, with an emphasis on understanding of cardiovascular disease as the primary cause of mortality and morbidity, both in Turkey and worldwide. This cross-sectional survey assessed 1138 nursing students enrolled in nursing schools in Istanbul, Turkey. Data were collected using the Cardiovascular Disease Risk Factors Knowledge Level (CARRF-KL) scale and questions from the Individual Characteristics Form about students' gender, age, level of education, and family cardiovascular health history, as well as smoking and exercise habits. Respondents demonstrated a high level of knowledge about cardiovascular disease, with years of education (p < 0.001), gender (p < 0.001), and high school type (p < 0.05) all significantly associated with CARRF-KL scores. However, more than half of the students were not aware that cardiovascular disease is the primary cause of mortality and morbidity in Turkey and worldwide. The majority of the respondents' body mass index (87%) and waist circumference values (females: 90.3%, males: 94.7%) were in the normal range and most were non-smokers (83.7%). However, more than half of the students did not exercise regularly and had inadequate dietary habits. Although students were knowledgeable about cardiovascular disease and associated risk factors, there were significant gaps in their knowledge; these should be addressed through improved nursing curricula. While students were generally healthy, they could improve their practice of health-promoting behaviors. © The European Society of Cardiology 2014.

Chronic hepatitis B virus (HBV) infection causes liver cancer and disproportionately affects the Asian community in the U.S. In order to advance HBV and liver cancer awareness and prevention, it is important to identify existing gaps in knowledge and preventive practices among Asian Americans. Therefore, the authors administered a written questionnaire to 199 adults in the Asian-American community of the San Francisco Bay Area, California. Although the majority of adults had at least a college education, knowledge regarding HBV transmission, prevention, symptoms, risks, and occurrence was low. Fewer than 60% reported having been tested for HBV, only 31% reported having been vaccinated against HBV, and only 44% reported having had their children vaccinated. Asians, especially those born in China or Southeast Asia, had significantly poorer knowledge regarding HBV and liver cancer than non-Asians. Those with higher knowledge levels were significantly more likely to have been tested for HBV and to have had their children vaccinated. Younger adults, women, Caucasians, more highly educated individuals, those not born in China or Hong Kong, and those with a personal or family history of liver disease were more likely to have taken preventive action against HBV. Our results suggest that HBV and liver cancer knowledge among Asian Americans, especially Chinese Americans, is poor, and that better knowledge is associated with increased preventive practices. Thus, there is a need for increased HBV education and improved community-based interventions to prevent HBV-related liver disease in the high-risk Asian-American community.
