Understanding of Alzheimer disease is fundamental for early diagnosis and to reduce caregiver burden. The objective of this study is to evaluate the degree of understanding of Alzheimer disease among informal caregivers and different segments of the general population through the Alzheimer's Disease Knowledge Scale. We assessed the knowledge of caregivers in different follow-up periods (less than one year, between 1 and 5 years, and over 5 years since diagnosis) and individuals from the general population. Alzheimer's Disease Knowledge Scale scores were grouped into different items: life impact, risk factors, symptoms, diagnosis, treatment, disease progression, and caregiving. A total of 419 people (215 caregivers and 204 individuals from the general population) were included in the study. No significant differences were found between groups for overall Alzheimer's Disease Knowledge Scale score (19.1 vs. 18.8, P = .9). There is a scarce knowledge of disease risk factors (49.3%) or the care needed (51.2%), while symptoms (78.6%) and course of the disease (77.2%) were the best understood aspects. Older caregiver age was correlated with worse Alzheimer's Disease Knowledge Scale scores overall and for life impact, symptoms, treatment, and disease progression (P < .05). Time since diagnosis improved caregivers' knowledge of Alzheimer disease symptoms (P = .00) and diagnosis (P = .05). Assessing the degree of understanding of Alzheimer disease is essential to the development of health education strategies both in the general population and among caregivers.

Background Heart disease is the number one killer of both men and women in the United States, yet a comprehensive and evidence-based heart disease knowledge assessment is currently not available. Purpose This paper describes the 2 phase development of a novel heart disease knowledge questionnaire. Methods After review and critique of the existing literature, a questionnaire addressing 5 central domains of heart disease knowledge was constructed. In Phase I, 606 undergraduates completed a 82-item questionnaire. In Phase II, 248 undergraduates completed a revised 74-item questionnaire. In both phases, item clarity and difficulty were evaluated, along with the overall factor structure of the scale. Results Exploratory and confirmatory factor analyses were used to reduce the scale to 30 items with fit statistics, CFI = .82, TLI = .88, and RMSEA = .03. Scores were correlated moderately positively with an existing scale and weakly positively with a measure of health literacy, thereby establishing both convergent and divergent validity. Discussion The finalized 30-item questionnaire is a concise, yet discriminating instrument that reliably measures participants' heart disease knowledge levels. Translation to Health Education Practice Health professionals can use this scale to assess their patients' heart disease knowledge so that they can create a tailored program to help their patients reduce their heart disease risk.

Motivation: Systems approaches to studying phenotypic relationships among diseases are emerging as an active area of research for both novel disease gene discovery and drug repurposing. Currently, systematic study of disease phenotypic relationships on a phenome-wide scale is limited because large-scale machine-understandable disease–phenotype relationship knowledge bases are often unavailable. Here, we present an automatic approach to extract disease–manifestation (D-M) pairs (one specific type of disease–phenotype relationship) from the wide body of published biomedical literature. Data and Methods: Our method leverages external knowledge and limits the amount of human effort required. For the text corpus, we used 119 085 682 MEDLINE sentences (21 354 075 citations). First, we used D-M pairs from existing biomedical ontologies as prior knowledge to automatically discover D-M–specific syntactic patterns. We then extracted additional pairs from MEDLINE using the learned patterns. Finally, we analysed correlations between disease manifestations and disease-associated genes and drugs to demonstrate the potential of this newly created knowledge base in disease gene discovery and drug repurposing. Results: In total, we extracted 121 359 unique D-M pairs with a high precision of 0.924. Among the extracted pairs, 120 419 (99.2%) have not been captured in existing structured knowledge sources. We have shown that disease manifestations correlate positively with both disease-associated genes and drug treatments. Conclusions: The main contribution of our study is the creation of a large-scale and accurate D-M phenotype relationship knowledge base. This unique knowledge base, when combined with existing phenotypic, genetic and proteomic datasets, can have profound implications in our deeper understanding of disease etiology and in rapid drug repurposing.

Cystic fibrosis (CF) is a life-shortening, burdensome disease requiring complex knowledge to manage the disease. Significant gaps in knowledge have been documented for parents, which may lead to unintentionally poor adherence and insufficient transfer of treatment responsibility from parents to adolescents. There are no current, validated measures of parent knowledge for this population and there are no measures that assess the knowledge required for day-to-day behavioral management of CF. We assessed the psychometric properties of the parent version of the Knowledge of Disease Management-Cystic Fibrosis measure (KDM-CF-P) using data from iCARE (I Change Adherence and Raise Expectations), a randomized control adherence intervention trial. A total of 196 parents in the iCARE standard care/control arm completed 35 items assessing their knowledge of disease management at their 12-month study visit, prior to beginning the intervention. Items were eliminated from the measure if they met the threshold for ceiling effects, were deemed clinically irrelevant, or did not correlate well with their intended scale. Item-to-total correlations, confirmatory factor analysis, discriminant function, reliability, and convergent validity were calculated. The KDM-CF-P (19 items) demonstrated internal consistency of KR20 = 0.60 on each scale and a two-scale structure. Convergent validity for knowledge scores was found with maternal education, family income, and type of medical insurance. Parents correctly answered approximately 85% of items on the KDM-CF-P. The KDM-CF-P psychometrics support a two-scale measure with clinical utility. It is useful for assessing gaps in knowledge that can be remediated through individualized, tailored interventions. © 2017 Wiley Periodicals, Inc.

Suboptimal care for people with dementia in hospital settings has been reported and is attributed to the lack of knowledge and inadequate attitudes in dementia care among health professionals. Educational interventions have been widely used to improve care outcomes; however, Chinese-language instruments used in dementia educational interventions for health professionals are lacking. The aims of this study were to select, translate and evaluate instruments used in dementia educational interventions for Chinese health professionals in acute-care hospitals. A cross-sectional study design was used. A modified stratified random sampling was used to recruit 442 participants from different levels of hospitals in Changsha, China. Dementia care competence was used as a framework for the selection and evaluation of Alzheimer's Disease Knowledge Scale and Dementia Care Attitudes Scale for health professionals in the study. These two scales were translated into Chinese using forward and back translation method. Content validity, test-retest reliability and internal consistency were assessed. Construct validity was tested using exploratory factor analysis. Known-group validity was established by comparing scores of Alzheimer's Disease Knowledge Scale and Dementia Care Attitudes Scale in two sub-groups. A person-centred care scale was utilised as a gold standard to establish concurrent validity of these two scales. Results demonstrated acceptable content validity, internal consistency, test-retest reliability and concurrent validity. Exploratory factor analysis presented a single-factor structure of the Chinese Alzheimer's Disease Knowledge Scale and a two-factor structure of the Chinese Dementia Care Attitudes Scale, supporting the conceptual dimensions of the original scales. The Chinese Alzheimer's Disease Knowledge Scale and Chinese Dementia Care Attitudes Scale demonstrated known-group validity evidenced by significantly higher scores identified from the sub-group with a longer work experience compared to those in the sub-group with less work experience. The use of dementia care competence as a framework to inform the selection and evaluation of instruments used in dementia educational interventions for health professionals has wide applicability in other areas. The results support that Chinese Alzheimer's Disease Knowledge Scale and Chinese Dementia Care Attitudes Scale are reliable and valid instruments for health professionals to use in acute-care settings.

To compare the psychometric performance of the Dementia Knowledge Assessment Scale (DKAS) and the Alzheimer's Disease Knowledge Scale (ADKS) when administered to a large international cohort before and after online dementia education. Comparative psychometric analysis with pre- and posteducation scale responses. The setting for this research encompassed 7,909 individuals from 124 countries who completed the 9-week Understanding Dementia Massive Open Online Course (MOOC). Volunteer respondents who completed the DKAS and ADKS before (n = 3,649) and after (n = 878) completion of the Understanding Dementia MOOC. Assessment and comparison of the DKAS and ADKS included evaluation of scale development procedures, interscale correlations, response distribution, internal consistency, and construct validity. The DKAS had superior internal consistency, wider response distribution with less ceiling effect, and better discrimination between pre- and posteducation scores and occupational cohorts than the ADKS. The 27-item DKAS is a reliable and preliminarily valid measure of dementia knowledge that is psychometrically and conceptually sound, overcomes limitations of existing instruments, and can be administered to diverse cohorts to measure baseline understanding and knowledge change. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

Health-promoting behaviors could serve as a major strategy to optimize long-term outcomes for adolescents with congenital heart disease. The associations assessed from a positive perspective of knowledge, attitudes, and practice model would potentially cultivate health-promoting behaviors during adolescence. The purpose of this study was to examine the relationships between disease knowledge, resilience, family functioning, and health-promoting behaviors in adolescents with congenital heart disease. A total of 320 adolescents with congenital heart disease who were aged 12-18 years were recruited from pediatric cardiology outpatient departments, and participated in a cross-sectional survey. The participants completed the Leuven Knowledge Questionnaire for Congenital Heart Disease; Haase Adolescent Resilience in Illness Scale; Family Adaptability, Partnership, Growth, Affection, and Resolve; and Adolescent Health Promotion scales. The collected data were analyzed using descriptive statistics and three multiple regression models. Greater knowledge of prevention of complications and higher resilience had a more powerful effect in enhancing health-promoting behaviors. Having symptoms and moderate or severe family dysfunction were significantly more negatively predictive of health-promoting behaviors than not having symptoms and positive family function. The third model explained 40% of the variance in engaging in health-promoting behaviors among adolescents with congenital heart disease. The findings of this study provide new insights into the role of disease knowledge, resilience, and family functioning in the health-promoting behavior of adolescents with congenital heart disease. Continued efforts are required to plan family care programs that promote the acquisition of sufficient disease knowledge and the development of resilience for adolescents with congenital heart disease.

As the population ages, the effects of Alzheimer's disease will be felt by all nurses. Providing proper care for people with Alzheimer's disease is difficult and requires specific skills, attitudes, and knowledge. Limited data exists regarding nursing students' attitudes and knowledge toward people with Alzheimer's disease, whether undergraduate education prepares students to care for this population, or the best methods to support students in learning in an innovative and interactive environment. The aim of this study was to determine the effect of different educational experiences on nursing students' knowledge and attitudes toward people with Alzheimer's disease and to explore nursing students' knowledge and attitudes surrounding the care of people with Alzheimer's disease. A convergent mixed method design. A three group (Alzheimer's disease clinical experience, online learning module, and no dementia-specific intervention), pretest and posttest design served as the quantitative arm of the study. A focus group discussion with themes extracted served as the qualitative piece of the study. College of Nursing in North Texas. Convenience sample of 94 senior level nursing students enrolled in the undergraduate nursing program's Community Health course. Students completed pre and posttest surveys which included Alzheimer's Disease Knowledge Scale, Dementia Attitudes Scale, and demographic questionnaire. Content analysis was conducted on focus group responses to qualitative interview questions. The Alzheimer's disease clinical group experienced increased knowledge and improved attitudes toward people with Alzheimer's disease compared with students who completed the online module or had no dementia-specific intervention. Four themes emerged from focus group data: Basic Alzheimer's disease knowledge, need for Alzheimer's disease experiential learning, negative feelings related to behaviors, and appropriate responses to behavioral and psychological symptoms of dementia. Experiential learning in the form of clinical placements increased knowledge and improved attitudes about Alzheimer's disease compared with an online module and no dementia-specific intervention.

Though attention deficit, hyperactivity disorder ADHD is a common problem in childhood. Thai teachers' knowledge regarding the disease has never been assessed. To identify knowledge of Thai teachers regardingADHD and its influencingfactors. Cross-sectional study was operated in three primary schools in Ayutthaya, Thailand. Standardized questionnaires comprised ofdemographic data, ADHD experiences and the Knowledge of Attention Deficit Disorder Scale, KADDS, were distributed to participating teachers. Results were reported using frequency, percent, mean, and standard deviation. Association between demographic and ADHD experiences and the KADDS score was identified by logistic regression analysis. Lack ofknowledge of ADHD among teachers was apparent. Only 19.4% of them passed the total scale of KADDS. Teachers under 31-years-old were more likely to pass general information and signs, symptoms & diagnosis subscales and total scale. In addition, familiarity with ADHD patients was associated with passing scores of general information subscale and total scale. Despite public awareness of ADHD, Thai teachers lacked knowledge concerning the disease. Young teachers were more acquainted with ADHD. Direct experience with ADHD patient might help teachers develop their knowledge on ADHD.

Background Community pharmacists' role in screening of several chronic diseases has been widely explored. The global health burden of chronic kidney disease is high; however, the progression and adverse outcomes can be prevented or delayed by detecting and treating the disease in its initial stages 1-3. Therefore, a web-based training program was developed to enhance pharmacists' knowledge and skills required to perform a chronic kidney disease screening service in a community setting. Objective The aim of this study was to evaluate the impact of a web-based training program on community pharmacists' knowledge and skills associated with chronic kidney disease screening. As secondary aim, pharmacists' satisfaction with the training program was assessed. Setting Community pharmacy practice. Method A web-based training program was developed by four pharmacists and a nephrologist. Quantitative data was collected by employing a self-administered, web-based questionnaire, which comprised a set of five multiple-choice knowledge questions and one clinical vignette to assess skills. A nine-item Likert scale was used to determine pharmacists' satisfaction with the training program. Main outcome measure Pharmacists' knowledge and skills scores at pre and post-training, reliability of the Likert scale, and the proportion of responses to the individual nine items of the satisfaction survey. Results Fifty pharmacists participated in the pre-questionnaire and 38 pharmacists completed the web-based training and post-questionnaire. Significant differences were observed in the knowledge scores (p < 0.001) and skills scores (p < 0.001) at pre- and post-training. Cronbach's alpha for the nine-item satisfaction scale was 0.73 and the majority pharmacists (92.1-100 %) were satisfied with the various aspects of the training program. Conclusion The web-based training program positively enhanced pharmacists' knowledge and skills associated with chronic kidney disease screening. These findings support further development and widespread implementation of the training program to facilitate health promotion and early identification of chronic kidney disease in a community setting.

Introduction Adherence to treatment and dietary restrictions is important for health outcomes of patients with chronic/end-stage kidney disease and hypertension. The relationship of adherence with nutritional and health literacy in children, adolescents, and young adults is not well understood. The current study examined the relationship of health literacy, nutrition knowledge, nutrition knowledge–behavior concordance, and medication adherence in a sample of children and young people with chronic/end-stage kidney disease and hypertension. Methods We enrolled 74 patients (aged 7–29 y) with a diagnosis of chronic/end-stage kidney disease and hypertension from the University of North Carolina Kidney Center. Participants completed instruments of nutrition literacy (Disease-Specific Nutrition Knowledge Test), health literacy (Newest Vital Sign), nutrition behavior (Nutrition Knowledge–Behavior Concordance Scale), and medication adherence (Morisky Medication Adherence Scale). Linear and binary logistic regressions were used to test the associations. Results In univariate comparisons, nutrition knowledge was significantly higher in people with adequate health literacy. Medication adherence was related to nutrition knowledge and nutrition knowledge–behavior concordance. Multivariate regression models demonstrated that knowledge of disease-specific nutrition restrictions did not significantly predict nutrition knowledge–behavior concordance scores. In logistic regression, knowledge of nutrition restrictions did not significantly predict medication adherence. Lastly, health literacy and nutrition knowledge–behavior concordance were significant predictors of medication adherence. Conclusion Nutrition knowledge and health literacy skills are positively associated. Nutrition knowledge, health literacy, and nutrition knowledge–behavior concordance are positively related to medication adherence. Future research should focus on additional factors that may predict disease-specific nutrition behavior (adherence to dietary restrictions) in children and young people with chronic conditions.

Patient adherence is integral to the effectiveness of prescribed treatment, and is associated with beneficial disease outcomes, yet in adolescents with cystic fibrosis, adherence is often sub-optimal. Multiple factors may contribute to treatment adherence, including disease knowledge and self-efficacy. In adolescents with cystic fibrosis: (i) to compare the disease knowledge of adolescents and their parents before transition to adult care; (ii) to determine the relationship between disease knowledge (adolescent, parent) and adherence; and (iii) to evaluate self-efficacy and its association with disease knowledge and adherence. Adolescents with cystic fibrosis and their parents were recruited from a tertiary children's hospital. Disease knowledge and self-efficacy was assessed using the Knowledge of Disease Management-CF and General Self-Efficacy Scales respectively. Using pharmacy records, medication possession ratio was calculated to measure treatment adherence in the preceding year. Thirty-nine adolescent (aged 12-17 (median 14) years) and parent pairs were recruited. Adherence to hypertonic saline, but not other medications, was significantly associated with disease knowledge in adolescents (r 2 = 0.40, P = 0.029). Mean (SD) adolescent self-efficacy was 30.8 (4.0), and not associated with disease knowledge or adherence. Mean (SD) disease knowledge was less in adolescents than parents (55 (16)% and 72 (14)% respectively, P < 0.001). Disease knowledge is sub-optimal in adolescents with cystic fibrosis, even in the 2 years immediately before transition to adult care. Given that adherence with some treatments has been associated with disease knowledge our results suggest the need for educational interventions in adolescents with cystic fibrosis to optimise self-management and health outcomes. © 2017 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

Background Managing community pharmacists can play a leading role in supporting community dwelling individuals with Alzheimer's disease and their caregivers. Objective The main purpose of this study was to assess knowledge of managing community pharmacists towards Alzheimer's disease and its pharmacological management. Setting Community pharmacies in the Maltese islands. Method A nationwide survey was conducted with full-time managing community pharmacists in possession of a tertiary education degree in pharmacy studies. The level of knowledge was investigated using the Alzheimer's Disease Knowledge Scale and the Alzheimer's Disease Pharmacotherapy Measure. Participants were also asked to rate a number of statements related to disease management. Results Maltese managing community pharmacists (57 % response rate) had inadequate knowledge on risk factors, caregiving issues and pharmacological management of Alzheimer's disease. Age and number of years working in a community pharmacy setting were found to be negatively correlated with increased knowledge. Conclusion The findings highlight the need of providing training and continued educational support to managing community pharmacists in order to provide quality advice to individuals with dementia and their caregivers in the community.

Alzheimer's disease is most common among the dementias and is characterized by gradual declines in functional and cognitive abilities. Caregivers including family members play a key role in providing critically needed care for these patients. This study compared the knowledge and attitudes of pre-healthcare and non-medical undergraduate students towards patients with Alzheimer's disease. A cross-sectional study was conducted involving quota sampling of 691 undergraduate students (369 pre-healthcare and 322 non-medical). A 28-item questionnaire was utilised comprising of closed-ended questions and some based on a scale rating. The students' knowledge of Alzheimer's disease was arranged into categories such as: 0 for no knowledge about Alzheimer's disease, 1 for very little knowledge about Alzheimer's disease, 2 for fair knowledge about Alzheimer's disease and 3 for great knowledge about Alzheimer's disease. The data was analysed using the computer software SPSS and the Chi squared test of independence was also used to determine which knowledge variables were independent of student's status. Overall, 40.01% of the students have great or fair knowledge of Alzheimer's disease, with that of pre-healthcare students being satisfactory (54.47%). Pre-healthcare students have a more positive attitude towards Alzheimer's disease and 82.2% of students wished to take advantage of predictive test for Alzheimer's disease. Age and genetics were identified as risk factors of the disease. Pre-healthcare students had greater understanding of Alzheimer's disease and depicted a more empathetic and caring attitude towards patients. This can be attributed mainly to their knowledge and exposure toward the disease.

Background A large-scale, highly accurate, machine-understandable drug-disease treatment relationship knowledge base is important for computational approaches to drug repurposing. The large body of published biomedical research articles and clinical case reports available on MEDLINE is a rich source of FDA-approved drug-disease indication as well as drug-repurposing knowledge that is crucial for applying FDA-approved drugs for new diseases. However, much of this information is buried in free text and not captured in any existing databases. The goal of this study is to extract a large number of accurate drug-disease treatment pairs from published literature. Results In this study, we developed a simple but highly accurate pattern-learning approach to extract treatment-specific drug-disease pairs from 20 million biomedical abstracts available on MEDLINE. We extracted a total of 34,305 unique drug-disease treatment pairs, the majority of which are not included in existing structured databases. Our algorithm achieved a precision of 0.904 and a recall of 0.131 in extracting all pairs, and a precision of 0.904 and a recall of 0.842 in extracting frequent pairs. In addition, we have shown that the extracted pairs strongly correlate with both drug target genes and therapeutic classes, therefore may have high potential in drug discovery. Conclusions We demonstrated that our simple pattern-learning relationship extraction algorithm is able to accurately extract many drug-disease pairs from the free text of biomedical literature that are not captured in structured databases. The large-scale, accurate, machine-understandable drug-disease treatment knowledge base that is resultant of our study, in combination with pairs from structured databases, will have high potential in computational drug repurposing tasks.

Data-driven phenotype analyses on Electronic Health Record (EHR) data have recently drawn benefits across many areas of clinical practice, uncovering new links in the medical sciences that can potentially affect the well-being of millions of patients. In this paper, EHR data is used to discover novel relationships between diseases by studying their comorbidities (co-occurrences in patients). A novel embedding model is designed to extract knowledge from disease comorbidities by learning from a large-scale EHR database comprising more than 35 million inpatient cases spanning nearly a decade, revealing significant improvements on disease phenotyping over current computational approaches. In addition, the use of the proposed methodology is extended to discover novel disease-gene associations by including valuable domain knowledge from genome-wide association studies. To evaluate our approach, its effectiveness is compared against a held-out set where, again, it revealed very compelling results. For selected diseases, we further identify candidate gene lists for which disease-gene associations were not studied previously. Thus, our approach provides biomedical researchers with new tools to filter genes of interest, thus, reducing costly lab studies. PMID:27578529
A knowledge based approach to matching human neurodegenerative disease and animal models

Neurodegenerative diseases present a wide and complex range of biological and clinical features. Animal models are key to translational research, yet typically only exhibit a subset of disease features rather than being precise replicas of the disease. Consequently, connecting animal to human conditions using direct data-mining strategies has proven challenging, particularly for diseases of the nervous system, with its complicated anatomy and physiology. To address this challenge we have explored the use of ontologies to create formal descriptions of structural phenotypes across scales that are machine processable and amenable to logical inference. As proof of concept, we built a Neurodegenerative Disease Phenotype Ontology (NDPO) and an associated Phenotype Knowledge Base (PKB) using an entity-quality model that incorporates descriptions for both human disease phenotypes and those of animal models. Entities are drawn from community ontologies made available through the Neuroscience Information Framework (NIF) and qualities are drawn from the Phenotype and Trait Ontology (PATO). We generated ~1200 structured phenotype statements describing structural alterations at the subcellular, cellular and gross anatomical levels observed in 11 human neurodegenerative conditions and associated animal models. PhenoSim, an open source tool for comparing phenotypes, was used to issue a series of competency questions to compare individual phenotypes among organisms and to determine which animal models recapitulate phenotypic aspects of the human disease in aggregate. Overall, the system was able to use relationships within the ontology to bridge phenotypes across scales, returning non-trivial matches based on common subsumers that were meaningful to a neuroscientist with an advanced knowledge of neuroanatomy. The system can be used both to compare individual phenotypes and also phenotypes in aggregate. This proof of concept suggests that expressing complex phenotypes using formal ontologies provides considerable benefit for comparing phenotypes across scales and species. PMID:23717278

Advances in overall management have led to an increasing number of adolescents with congenital heart disease reaching adulthood. This study aimed to evaluate the health-related quality of life in adolescents with heart disease, and examine its relationship with the adolescents' knowledge and understanding of their congenital heart disease, its severity, and its relationship to the degree of anxiety and depression, feeling of optimism and sense of coherence experienced by the adolescents together with their social support. Adolescents with heart disease were recruited from an ambulatory setting at a tertiary centre. Patients completed self-report questionnaires including the Paediatric Quality of Life Inventory 3.0-Cardiac Module, a questionnaire assessing the adolescents' knowledge of their cardiac condition, the Hospital Anxiety and Depression Scale, Multidimensional Scale of Perceived Social Support, Life Orientation Test-Revised, and Sense of Coherence-13, supplemented by clinical information provided by the attending cardiologists. A total of 114 patients aged 12-20 years were recruited over 15 months. In all, 98% of patients were in New York Heart Association class I. Their health-related quality of life was found to positively correlate with a low level of anxiety and depression (Pearson correlation, r = -0.57, p < 0.001), a good knowledge of their cardiac condition (r = 0.31, p < 0.01), feelings of optimism (r = 0.39, p < 0.001), adequate social support (r = 0.27, p < 0.01), and a strong sense of coherence (r = 0.24, p < 0.01). Adolescents' knowledge and understanding of their cardiac abnormality together with an improved sense of well-being had a positive influence on their health-related quality of life.

Background Diabetes affects more than 29 million people in the US and requires daily self-management in addition to knowledge of the disease. Three knowledge assessments used are the Michigan Brief Diabetes Knowledge Test (DKT), Starr County Diabetes Knowledge Questionnaire (DKQ), and Kaiser DISTANCE Survey (DISTANCE). Purpose The purpose of the study was to test the discriminate validity of 3 diabetes knowledge scales and determine which is best associated with diabetes self-care and glycemic control. Methods Three hundred sixty-one adults with type 2 diabetes were recruited from primary care clinics. Four analyses were conducted to investigate the validity and relationships of the scale: alpha statistic to test internal validity, factor analysis to determine how much of the variance was explained, Pearson's correlation between the 3 scales, and Pearson's correlation between each scale, self-care, and outcomes. Results The DKQ had an alpha of 0.75, the DKT had an alpha of 0.49, and DISTANCE had an alpha of 0.36. The DKQ was significantly correlated with glycemic control. The DKT scale was significantly associated with general diet, the DISTANCE survey was significantly associated with exercise, and both DKT and DISTANCE were significantly associated with foot care. Conclusion Correlations among the 3 scales were modest, suggesting the scales are not measuring the same underlying construct. These findings indicate that researchers should carefully select scales appropriate for study goals or to appropriately capture the information being sought to inform practice.

The purpose of this study was to evaluate the effectiveness of a 5-week, 1 hour per week heart disease prevention program for sedentary female municipal workers with known heart disease risk factors. The program was designed to improve participants' knowledge and perceptions of their personal susceptibility to heart disease. In targeting an ethnically diverse, lower income working population, the researchers also sought to contribute to one of the goals of Healthy People 2010, the elimination of health disparities, specifically the reduction of health disparities in heart disease by 25% by the year 2010. A one-group, repeated measures, quasi-experimental design was employed. Forty-eight women 25 to 66 years old responded to the solicitation and participated in the program. Seventy-five percent were African American, 23% were White, and 2% were Latino. Participants completed a 33-item heart disease knowledge questionnaire, demographic questions, and a single visual analog scale statement to assess perceived susceptibility. Fifty-eight percent of the participants improved their knowledge of heart disease and 50% of the participants increased their perception of susceptibility to heart disease from pre- to post-intervention. The greatest improvement in knowledge and awareness of susceptibility occurred for those with limited knowledge and low perceptions of susceptibility. The gains from this workplace health education project for largely minority female municipal workers were modest, but notable. A workplace health education program for women targeted at increasing their knowledge of heart disease may also increase their perceptions of susceptibility to heart disease.

To explore decisional conflict and its influencing factors on choosing dialysis modality in patients with end-stage renal diseases. The influencing factors investigated include demographics, predialysis education, dialysis knowledge, decision self-efficacy and social support. Making dialysis modality decisions can be challenging for patients with end-stage renal diseases; there are pros and cons to both haemodialysis and peritoneal dialysis. Patients are often uncertain as to which one will be the best alternative for them. This decisional conflict increases the likelihood of making a decision that is not based on the patient's values or preferences and may result in undesirable postdecisional consequences. Addressing factors predisposing patients to decisional conflict helps to facilitate informed decision-making and then to improve healthcare quality. A predictive correlational cross-sectional study design was used. Seventy patients were recruited from the outpatient dialysis clinics of two general hospitals in Taiwan. Data were collected with study questionnaires, including questions on demographics, dialysis modality and predialysis education, the Dialysis Knowledge Scale, the Decision Self-Efficacy scale, the Social Support Scale, and the Decisional Conflict Scale. The mean score on the Decisional Conflict Scale was 29.26 (SD = 22.18). Decision self-efficacy, dialysis modality, predialysis education, professional support and dialysis knowledge together explained 76.4% of the variance in decisional conflict. Individuals who had lower decision self-efficacy, did not receive predialysis education on both haemodialysis and peritoneal dialysis, had lower dialysis knowledge and perceived lower professional support reported higher decisional conflict on choosing dialysis modality. When providing decisional support to predialysis stage patients, practitioners need to increase patients' decision self-efficacy, provide both haemodialysis and peritoneal dialysis predialysis education, increase dialysis knowledge and provide professional support. © 2017 John Wiley & Sons Ltd.

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.

The implementation of screening for rheumatic heart disease at a population-scale would require a considerable increase in human resources. Training nonexpert staff in echocardiography requires appropriate methods and materials. This pre/post study aims to measure the change in the knowledge and confidence of a group of health workers after a computer-assisted training intervention in basic echocardiography for rheumatic heart disease. A syllabus of self-guided, computer-based modules to train nonexpert health workers in basic echocardiography for rheumatic heart disease was developed. Thirty-eight health workers from Uganda participated in the training. Using a pre/post design, identical test instruments were administered before and after the training intervention, assessing the knowledge (using multiple-choice questions) and confidence (using Likert scale questions) in clinical science and echocardiography. The mean total score on knowledge tests rose from 44.8% to 85.4% (mean difference: 40.6%, 95% confidence interval [CI]: 35.4% to 45.8%), with strong evidence for an increase in scores across all knowledge theme areas (p < 0.001). Increased confidence with each key aspect was reported, and there was strong evidence for an increase in the mean score for confidence scales in clinical science (difference: 7.1, 95% CI: 6.2 to 8.0; p < 0.001) and echocardiography (difference: 18.3, 95% CI: 16.6 to 20.0; p < 0.001). The training program was effective at increasing knowledge and confidence for basic echocardiography in nonexpert health workers. Use of computer-assisted learning may reduce the human resource requirements for training staff in echocardiography. Copyright © 2016 World Heart Federation (Geneva). Published by Elsevier B.V.

Hypertension is the second most common cause of chronic kidney disease (CKD). Therefore, the aims of the study were to assess the knowledge, attitudes and practices (KAP) of hypertensive patients towards prevention and early detection of CKD, and to determine the clinical and socio-demographic factors, which affect the KAP regarding prevention of CKD. A cross-sectional study was held using the CKD screening Index to assess the KAP of 374 hypertensive patients who were selected from multiple primary healthcare centers in Nablus, Palestine. The CKD Screening Index is formed of three scales. First, the knowledge scale was a dichotomous scale of 30 items, while the attitude scale used 5-point Likert-type scale for 18 items and finally the practice scale was measured using 4-point Likert-type scale for 12 items. Multiple linear regression analysis was used to determine the association between clinical and socio-demographic factors and practices. In total, 374 hypertensive patients participated in the study. The mean age of participants was 59.14 ± 10.4 years, (range 26-85). The median (interquartile range) of the knowledge, attitude, and practice scores of hypertensive patients towards prevention and early detection of CKD were 20 (16-23), 69 (65-72), and 39 (36-42), respectively. In multiple linear regression analysis, patients age < 65 years ( p < 0.001) and patients with high education level ( p = 0.009) were the only factors significantly associated with higher knowledge scores. Additionally, patients age < 65 years ( p = 0.007), patients with high income ( p = 0.005), and patients with high knowledge score ( p < 0.001) were the only factors significantly associated with higher attitude scores. Furthermore, regression analysis showed that patients with higher total knowledge ( p = 0.001) as well as higher total attitudes scores towards CKD prevention ( p < 0.001), male gender ( p = 0.048), and patients with normal body mass index (BMI) ( p = 0.026) were statistically significantly associated with higher practice score towards CKD prevention. Among hypertensive patients, higher scores for total knowledge and attitudes toward prevention, male sex, and normal BMI were associated with modestly higher scores for prevention practices. Finally the findings may encourage healthcare workers to give better counseling to improve knowledge.

Background Heart disease knowledge is an important concept for health education, yet there is lack of evidence on proper validated instruments used to measure levels of heart disease knowledge in the Malaysian context. Methods A cross-sectional, survey design was conducted to examine the psychometric properties of the adapted English version of the Heart Disease Knowledge Questionnaire (HDKQ). Using proportionate cluster sampling, 788 undergraduate students at Universiti Sains Malaysia, Malaysia, were recruited and completed the HDKQ. Item analysis and confirmatory factor analysis (CFA) were used for the psychometric evaluation. Construct validity of the measurement model was included. Results Most of the students were Malay (48%), female (71%), and from the field of science (51%). An acceptable range was obtained with respect to both the difficulty and discrimination indices in the item analysis results. The difficulty index ranged from 0.12–0.91 and a discrimination index of ≥ 0.20 were reported for the final retained 23 items. The final CFA model showed an adequate fit to the data, yielding a 23-item, one-factor model [weighted least squares mean and variance adjusted scaled chi-square difference = 1.22, degrees of freedom = 2, P-value = 0.544, the root mean square error of approximation = 0.03 (90% confidence interval = 0.03, 0.04); close-fit P-value = > 0.950]. Conclusion Adequate psychometric values were obtained for Malaysian undergraduate university students using the 23-item, one-factor model of the adapted HDKQ. PMID:27660543

Objective The 12-item Partners in Health scale (PIH) was developed in Australia to measure self-management behaviour and knowledge in patients with chronic diseases, and has undergone several changes. Our aim was to assess the construct validity and reliability of the latest PIH version in Dutch COPD patients. Methods The 12 items of the PIH, scored on a self-rated 9-point Likert scale, are used to calculate total and subscale scores (knowledge; coping; recognition and management of symptoms; and adherence to treatment). We used forward-backward translation of the latest version of the Australian PIH to define a Dutch PIH (PIH(Du)). Mokken Scale Analysis and common Factor Analysis were performed on data from a Dutch COPD sample to investigate the psychometric properties of the Dutch PIH; and to determine whether the four-subscale solution previously found for the original Australian PIH could be replicated for the Dutch PIH. Results Two subscales were found for the Dutch PIH data (n = 118); 1) knowledge and coping; 2) recognition and management of symptoms, adherence to treatment. The correlation between the two Dutch subscales was 0.43. The lower-bound of the reliability of the total scale equalled 0.84. Factor analysis indicated that the first two factors explained a larger percentage of common variance (39.4% and 19.9%) than could be expected when using random data (17.5% and 15.1%). Conclusion We recommend using two PIH subscale scores when assessing self-management in Dutch COPD patients. Our results did not support the four-subscale structure as previously reported for the original Australian PIH. PMID:27564410

Recent scientific advances have accumulated a tremendous amount of biomedical knowledge providing novel insights into the relationship between molecular and cellular processes and diseases. Literature mining is one of the commonly used methods to retrieve and extract information from scientific publications for understanding these associations. However, due to large data volume and complicated associations with noises, the interpretability of such association data for semantic knowledge discovery is challenging. In this study, we describe an integrative computational framework aiming to expedite the discovery of latent disease mechanisms by dissecting 146,245 disease-gene associations from over 25 million of PubMed indexed articles. We take advantage of both Latent Dirichlet Allocation (LDA) modeling and network-based analysis for their capabilities of detecting latent associations and reducing noises for large volume data respectively. Our results demonstrate that (1) the LDA-based modeling is able to group similar diseases into disease topics; (2) the disease-specific association networks follow the scale-free network property; (3) certain subnetwork patterns were enriched in the disease-specific association networks; and (4) genes were enriched in topic-specific biological processes. Our approach offers promising opportunities for latent disease-gene knowledge discovery in biomedical research.

The Unified Medical Language System (UMLS) is the largest thesaurus in the biomedical informatics domain. Previous works have shown that knowledge constructs comprised of transitively-associated UMLS concepts are effective for discovering potentially novel biomedical hypotheses. However, the extremely large size of the UMLS becomes a major challenge for these applications. To address this problem, we designed a k-neighborhood Decentralization Labeling Scheme (kDLS) for the UMLS, and the corresponding method to effectively evaluate the kDLS indexing results. kDLS provides a comprehensive solution for indexing the UMLS for very efficient large scale knowledge discovery. We demonstrated that it is highly effective to use kDLS paths to prioritize disease-gene relations across the whole genome, with extremely high fold-enrichment values. To our knowledge, this is the first indexing scheme capable of supporting efficient large scale knowledge discovery on the UMLS as a whole. Our expectation is that kDLS will become a vital engine for retrieving information and generating hypotheses from the UMLS for future medical informatics applications. PMID:22154838

In essence, the virtual physiological human (VPH) is a multiscale representation of human physiology spanning from the molecular level via cellular processes and multicellular organization of tissues to complex organ function. The different scales of the VPH deal with different entities, relationships and processes, and in consequence the models used to describe and simulate biological functions vary significantly. Here, we describe methods and strategies to generate knowledge environments representing molecular entities that can be used for modelling the molecular scale of the VPH. Our strategy to generate knowledge environments representing molecular entities is based on the combination of information extraction from scientific text and the integration of information from biomolecular databases. We introduce @neuLink, a first prototype of an automatically generated, disease-specific knowledge environment combining biomolecular, chemical, genetic and medical information. Finally, we provide a perspective for the future implementation and use of knowledge environments representing molecular entities for the VPH.

Patient education forms a cornerstone of management of inflammatory bowel disease (IBD). The Internet has opened new avenues for information gathering. To determine the relationship between different information sources and patient knowledge and anxiety in patients with IBD. The use of information sources in patients with IBD was examined via questionnaire. Anxiety was assessed with the hospital anxiety and depression scale and disease-related patient knowledge with the Crohn's and colitis knowledge score questionnaires. Associations between these outcomes and demographics, disease-related factors, and use of different information sources were analysed using linear regression analysis. Of 307 patients (165 Crohn's disease, 142 ulcerative colitis) 60.6% were female. Participants used the hospital IBD team (82.3%), official leaflets (59.5%), and official websites (53.5%) most frequently in contrast to alternative health websites (9%). University education (P < 0.001), use of immunosuppressants (P = 0.025), Crohn's and Colitis UK membership (P = 0.001), frequent use of the hospital IBD team (P = 0.032), and frequent use of official information websites (P = 0.005) were associated with higher disease-related patient knowledge. Female sex (P = 0.004), clinically active disease (P < 0.001), frequent use of general practitioners (P = 0.014), alternative health websites (homoeopathy, nutritionists, etc.) (P = 0.004) and random links (P = 0.016) were independently associated with higher anxiety. Different patient information sources are associated with better knowledge or worse anxiety levels. Face-to-face education and written information materials remain the first line of patient education. Patients should be guided towards official information websites and warned about the association between the use of alternative health websites or random links and anxiety. © 2016 John Wiley & Sons Ltd.

The attitude of patients with epilepsy towards their disease is an important factor in disease management and quality of life. The aim of this study was to define the attitudes of patients with epilepsy towards their disease and the factors that affect their attitudes. This descriptive study was performed on patients admitted to an epilepsy outpatient clinic of a university hospital between May and September 2015. The sample consisted of 70 patients over 18years of age with a diagnosis of epilepsy and no health problem other than epilepsy. Patients with no seizure in the last two years were excluded. The Epilepsy Attitude Scale was used to evaluate attitudes of the patients towards epilepsy; the Epilepsy Knowledge Scale, Rotter's Locus of Control Scale, Hospital Anxiety and Depression Scale (HADS), and the Quality of Life in Epilepsy-10 (QOLIE-10) were used to investigate the attitude-related factors. Among the 70 participants, 43 were female, and the mean age was 31.4years. The educational level of the patients was lower (primary school) in 38.6% of the sample, and 18.6% were unemployed. Time since diagnosis was 15.1years, 75.7% of the participants had generalized type of seizures, and more than half had seizures more frequently than once a month. The mean score of the attitude scale was 59.7±6.62 (range: 14-70). The attitudes of the patients towards epilepsy were found to be related to their educational status, living alone, and the attitudes of their families. The attitude scores were also related to the level of knowledge on epilepsy, stigma, and depression. Furthermore, the attitude was found to be correlated with quality of life. Patients with epilepsy had moderate-to-good attitude towards their disease. It was observed that the attitude was related to the knowledge, stigma, and depression rather than to demographic factors and the seizures, and furthermore, the attitude was found to be correlated with quality of life.

The 'Teddy Bear Hospital' is a medical students' project, which has been increasingly established in many countries. To evaluate this concept, we examined the effects of a German Teddy Bear Hospital on children's knowledge relating to their body, health and disease. Using a quasi-experimental pre/post design, we examined 131 preschool children from 14 German kindergartens with pictorial interview-based scales. The analysis of covariance revealed that the children who visited the Teddy Bear Hospital had a significantly better knowledge concerning their body, health and disease than the children from the control group. This German Teddy Bear Hospital is a good health education vehicle for preschool children. © The Author(s) 2013.

In this study, we described the content and characteristics of 40 non-proprietary websites offering information about chronic kidney disease (CKD) and evaluated their information quality using the DISCERN scale and readability using Flesch Reading Ease and Flesch-Kincaid grade level. The areas in which the websites scored the lowest on the DISCERN scale were whether the website discussed knowledge gaps, presented balanced information, and was clear about the information source. Websites that rated higher quality on the DISCERN scale were more difficult to read. The quality and readability of many websites about CKD to be used as meaningful educational resources for patients who desire to learn more about CKD and treatment options remain inadequate.

The knowledge that one carries the apolipoprotein E (APOE) ε4 allele risk factor for Alzheimer's disease was recently found to have little short-term psychological risk. The authors investigated the impact of knowledge of carrying the risk allele on subjective ratings of memory and objective memory test performance of older adults. Using a nested case-control design, the authors administered objective verbal and visual memory tests and self-rating scales of memory function to 144 cognitively normal older adults (ages 52-89) with known APOE genotype who knew (ε4+, N=25; ε4-, N=49) or did not know (ε4+, N=25; ε4-, N=45) their genotype and genetic risk for Alzheimer's disease prior to neuropsychological evaluation. Significant genotype-by-disclosure interaction effects were observed on several memory rating scales and tests of immediate and delayed verbal recall. Older adults who knew their ε4+ genotype judged their memory more harshly and performed worse on an objective verbal memory test than did ε4+ adults who did not know. In contrast, older adults who knew their ε4- genotype judged their memory more positively than did ε4- adults who did not know, but these groups did not differ in objective memory test performance. Informing older adults that they have an APOE genotype associated with an increased risk of Alzheimer's disease can have adverse consequences on their perception of their memory abilities and their performance on objective memory tests. The patient's knowledge of his or her genotype and risk of Alzheimer's disease should be considered when evaluating cognition in the elderly.

This study aims to assess the impact of a structured education and home exercise programme in daily practice patients with ankylosing spondylitis. A total of 756 patients with ankylosing spondylitis (72% males, mean age 45 years) participated in a 6-month prospective multicentre controlled study, 381 of whom were randomised to an education intervention (a 2-hour informative session about the disease and the implementation of a non-supervised physical activity programme at home) and 375 to standard care (controls). Main outcome measures included Bath Ankylosing Spondylitis Disease Activity and Functional Index (BASDAI, BASFI). Secondary outcome measures were 0-10 cm visual analog scale (VAS) for total pain, nocturnal pain and global disease activity and quality of life (ASQoL), knowledge of disease (self-evaluation ordinal scale) and daily exercise (diary card). At 6 months, the adjusted mean difference between control and educational groups for BASDAI was 0.32, 95% confidence interval (CI) 0.10-0.54, p=0.005, and for BASFI 0.31, 95%CI 0.12-0.51, p=0.002. Significant differences were found also in VAS for total pain, patient´s global assessment and in ASQoL. Patients in the education group increased their knowledge about the disease and its treatments significantly (p<0.001) and practised more regular exercise than controls (p<0.001). A structured education and home exercise programme for patients with ankylosing spondylitis in daily practice was feasible and helped to increase knowledge and exercise. Although statistically significant, the magnitudes of the clinical benefits in terms of disease activity and physical function were poor.

The effect of 3 types of intervention schemes on the scientific knowledge and attitude of Kanuri towards malaria, diarrhoea and dysentery and intestinal worms was assessed using the Likert scale response type statements. 1383 respondents in our identical Kanuri villages were used in the study. The effect of still pictures and card games (Goramari), drama songs, storytelling and discussions (Yerimari) and a combination of both (Shetimari) on knowledge and attitude was tested. Gotimari was used as the control. Quarterly assessment of changes in knowledge and attitude showed that Goramari was the least effective while Yerimari and Shetimari were the most effective. Women were more influenced than men by health education schemes which involve drama songs and stories while card games and still pictures had very little effect on them (women). The implication of these findings on disease management through health education is discussed.

As a high-quality diet is associated with a lower risk for several diseases and all-cause mortality, current nutrition education tools provide people with information regarding how to build a healthy and a balanced meal. To assess this basic nutrition knowledge, the research aim was to develop and validate a brief scale to measure the Practical Knowledge about Balanced meals (PKB-7). A pool of 25 items was pretested with experts and laypeople before being tested on a random sample in Switzerland (n=517). For item selection, a Rasch model analysis was applied. The validity and reliability of the new scale were assessed by three additional studies including laypeople (n=597; n=145) and nutrition experts (n=59). The final scale consists of seven multiple-choice items, which met the assumptions of the Rasch model. The validity of the new scale was shown by several aspects: the Rasch model was replicated in a second study, and nutrition experts achieved significantly higher scores than laypeople (t(148)=20.27, P<0.001, d=1.78). In addition, the PKB-7 scale was correlated with other nutrition-related constructs and associated with reported vegetable consumption. Test-retest reliability (r=0.68, P<0.001) was acceptable. The PKB-7 scale is a reliable and a valid Rasch-based instrument in Swiss citizens aged between 18 and 80 years for measuring the practical knowledge about balanced meals based on current dietary guidelines. This brief and easy-to-use scale is intended for application in both research and practice.

Background Patients with Lynch Syndrome, the most common hereditary colorectal cancer syndrome, benefit from genetic education and family counseling regarding diagnostic testing and cancer surveillance/prevention recommendations. Although genetic counseling is currently the most common venue where such education and counseling takes place, little is known about the level of disease knowledge and education needs as directly reported by patients and families with Lynch Syndrome. Furthermore, experiences with forums for larger-scale knowledge transfer have been limited in the current literature. Methods We conducted a one-day interactive multidisciplinary patient conference, designed to complement individual genetic counseling for updating disease knowledge, supportive networking and needs assessment among Lynch Syndrome patients and their family members. The patient conference was designed utilizing the conceptual framework of action research. Paired pre- and post-conference surveys were administered to 44 conference participants anonymously to assess patient-reported disease knowledge and education needs. Results A multidisciplinary team of expert providers utilized a variety of educational formats during the one-day conference. Four main focus areas were: genetic testing, surveillance/prevention, living with Lynch Syndrome, and update on research. Thirty-two participants (73%) completed the pre-conference, and 28 (64%) participants completed the post-conference surveys. Nineteen respondents were affected and the remaining were unaffected. The scores of the disease-knowledge items significantly increased from 84% pre- to 92% post-conference (p = 0.012). Patients reported a high level of satisfaction and identified further knowledge needs in nutrition (71%), surveillance/prevention options (71%), support groups (36%), cancer risk assessment (32%), active role in medical care (32%), and research opportunities (5%). Conclusion Our experience with a dedicated patient education conference focused on Lynch Syndrome demonstrated that such an educational format is effective for updating or reinforcing disease knowledge, for identifying patient-reported unmet educational needs, as well as for peer-support.

Modern high-throughput techniques offer immense opportunities to investigate whole-systems behavior, such as those underlying human diseases. However, the complexity of the data presents challenges in interpretation, and new avenues are needed to address the complexity of both diseases and data. Constraint-based modeling is one formalism applied in systems biology. It relies on a genome-scale reconstruction that captures extensive biochemical knowledge regarding an organism. The human genome-scale metabolic reconstruction is increasingly used to understand normal cellular and disease states because metabolism is an important factor in many human diseases. The application of human genome-scale reconstruction ranges from mere querying of the model as a knowledge base to studies that take advantage of the model's topology and, most notably, to functional predictions based on cell- and condition-specific metabolic models built based on omics data.An increasing number and diversity of biomedical questions are being addressed using constraint-based modeling and metabolic models. One of the most successful biomedical applications to date is cancer metabolism, but constraint-based modeling also holds great potential for inborn errors of metabolism or obesity. In addition, it offers great prospects for individualized approaches to diagnostics and the design of disease prevention and intervention strategies. Metabolic models support this endeavor by providing easy access to complex high-throughput datasets. Personalized metabolic models have been introduced. Finally, constraint-based modeling can be used to model whole-body metabolism, which will enable the elucidation of metabolic interactions between organs and disturbances of these interactions as either causes or consequence of metabolic diseases. This chapter introduces constraint-based modeling and describes some of its contributions to systems biomedicine.

The objective of this study was to evaluate the efficacy of Modular Education Program for Children with Epilepsy and Their Parents on disease management. The program was prepared by researchers in an interdisciplinary team. Children with epilepsy and their parents were included in a randomized controlled study using a pre-posttest design. All participants of the modular education program (n=184 (92 children and their 92 parents')) answered a lot of scales immediately before the program. The researcher presented the modular education program, which included eight modules (four for the children and four for the parents), to the children and parents in the intervention group using interactive teaching methods. And all participants of the modular education program answered all scales immediately after the program and one-month, three-month follow-ups. The control group not participating in the modular education program (n=100 (50 children, 50 parents)) also answered all scales in all follow-ups. Scales used the study comprised epilepsy-specific outcome measures (e.g., knowledge, self-efficacy related to seizures, quality of life and anxiety). The statistical analyses of the study data were performed using SAS 9.3 software. Children in intervention group significantly improved in knowledge (p<0.001), self-efficacy about seizures (p<0.001), and quality of life (p<0.001) compared with the control group. The parents in the intervention group also significantly improved in knowledge about epilepsy (p<0.001) compared with the control group. However, anxiety of the parents in the intervention group significantly increased (p<0.001). The efficacy of the Modular Education Program for Children with Epilepsy and Their Parents on disease management was confirmed. The results indicate that using interactive teaching methods help children with epilepsy and their parents in improving knowledge, self-efficacy about seizures and quality of life. All health professionals who work with children with epilepsy and their parents should provide these modular education programs regularly. Copyright © 2017 Elsevier Inc. All rights reserved.

The Functional Rating Scale Taskforce for pre-Huntington Disease (FuRST-pHD) is a multinational, multidisciplinary initiative with the goal of developing a data-driven, comprehensive, psychometrically sound, rating scale for assessing symptoms and functional ability in prodromal and early Huntington disease (HD) gene expansion carriers. The process involves input from numerous sources to identify relevant symptom domains, including HD individuals, caregivers, and experts from a variety of fields, as well as knowledge gained from the analysis of data from ongoing large-scale studies in HD using existing clinical scales. This is an iterative process in which an ongoing series of field tests in prodromal (prHD) and early HD individuals provides the team with data on which to make decisions regarding which questions should undergo further development or testing and which should be excluded. We report here the development and assessment of the first iteration of interview questions aimed to assess "Anger and Irritability" and "Obsessions and Compulsions" in prHD individuals.

The goal of our NSF-sponsored Division of Behavioral and Cognitive Sciences grant is to create a multidisciplinary approach to develop spatially explicit models of vector-borne disease risk using Chagas disease as our model. Chagas disease is a parasitic disease endemic to Latin America that afflicts an estimated 10 million people. The causative agent (Trypanosoma cruzi) is most commonly transmitted to humans by blood feeding triatomine insect vectors. Our objectives are: (1) advance knowledge on the multiple interacting factors affecting the transmission of Chagas disease, and (2) provide next generation genomic and spatial analysis tools applicable to the study of other vector-borne diseases worldwide. This funding is a collaborative effort between the RSENR (UVM), the School of Engineering (UVM), the Department of Biology (UVM), the Department of Biological Sciences (Loyola (New Orleans)) and the Laboratory of Applied Entomology and Parasitology (Universidad de San Carlos). Throughout this five-year study, multi-educational groups (i.e., high school, undergraduate, graduate, and postdoctoral) will be trained in systems modeling. This systems approach challenges students to incorporate environmental, social, and economic as well as technical aspects and enables modelers to simulate and visualize topics that would either be too expensive, complex or difficult to study directly (Yasar and Landau 2003). We launch this research by developing a set of multi-scale, epidemiological models of Chagas disease risk using STELLA® software v.9.1.3 (isee systems, inc., Lebanon, NH). We use this particular system dynamics software as a starting point because of its simple graphical user interface (e.g., behavior-over-time graphs, stock/flow diagrams, and causal loops). To date, high school and undergraduate students have created a set of multi-scale (i.e., homestead, village, and regional) disease models. Modeling the system at multiple spatial scales forces recognition that the system's structure generates its behavior; and STELLA®'s graphical interface allows researchers at multiple educational levels to observe patterns and trends as the system changes over time. Graduate students and postdoctoral researchers will utilize these initial models to more efficiently communicate and transfer knowledge across disciplines prior to generating more novel and complex disease risk models. The hope is that these models will improve causal viewpoints, understanding of the system patterns, and how to best mitigate disease risk across multiple spatial scales.

In this study, we described the content and characteristics of 40 non-proprietary websites offering information about chronic kidney disease (CKD) and evaluated their information quality using the DISCERN scale and readability using Flesch Reading Ease and Flesch-Kincaid grade level. The areas in which the websites scored the lowest on the DISCERN scale were whether the website discussed knowledge gaps, presented balanced information, and was clear about the information source. Websites that rated higher quality on the DISCERN scale were more difficult to read. The quality and readability of many websites about CKD to be used as meaningful educational resources for patients who desire to learn more about CKD and treatment options remain inadequate.

The purpose of this descriptive correlational study was to examine health literacy and its association with diabetes knowledge, perceived self-efficacy and disease self-management among African Americans with diabetes mellitus. Fifty English-speaking, adult African American participants with diabetes mellitus were recruited from a community health center and a church located in the Midwestern United States. Data were collected at a single point in time utilizing the Rapid Estimate of Adult Literacy in Medicine (REALM), Diabetes Knowledge Test (DKT), Diabetes Self-efficacy Scale, and Summary of Diabetes Self-care Activities (SDSCA) Questionnaire. Bivariate associations were identified for health literacy with diabetes knowledge level; diabetes knowledge level with dietary self-care activities; and self-efficacy with dietary, exercise, and foot care self-care activities. Diabetes knowledge level and self-efficacy were independent predictors for dietary self-care activities, while self efficacy was the sole independent predictor for foot self-care. Means for health literacy and diabetes self-care activities were influenced by demographic factors examined.

Evidence indicates that a healthy lifestyle can reduce cardiovascular disease risk, yet many people engage in unhealthy behaviors. New technologies such as coronary artery calcium (CAC) screening detect atherosclerosis before clinical disease is manifested. Knowledge of an abnormal finding could provide the "teachable moment" to enhance motivation for change. The aim of this study was to examine how knowledge of CAC score affects risk perception, likelihood of taking action, and health-promoting behavior change in persons at high risk for cardiovascular disease. This study used a descriptive prospective design with 174 high-risk adults (≥3 major risk factors) recruited at a radiology center offering CAC scans. Baseline self-report surveys using the Perception of Risk of Heart Disease Scale, the Benefits and Barriers Scale, the Quality of Life Index, and the Health-Promoting Lifestyle Profile II were completed immediately after a screening CAC scan but before results were known. Follow-up occurred 3 months later using mailed packets. Participants' mean age was 58 years; 62% were men, 89% were white, and most were well educated. There was no significant change in risk perception scores over time or between groups, except for a positive interaction in the moderate-risk group (CAC scores of 101-400) (P = .004). Quality of life remained unchanged. Health-promoting behavior changes increased in all groups over time (P < .001). McNemar χ² analysis indicated that risk reduction medication use increased in all groups, with a significant increase in statin (P < .001) and aspirin (P < .001) intake. Predictors of behavior change were perceived barriers (β = -.41; P < .001) and quality of life (β = .44; P < .001). Knowledge of CAC score does impact risk perception for some at-risk groups. This knowledge does enhance motivation for behavior change. Knowledge of CAC score does not impact quality of life. It is hoped that through improved understanding of the effect of CAC scoring on behavior change, nurses can better assist patients to modify behaviors during teachable moments.

To prospectively identify different coping strategies among newly diagnosed amyotrophic lateral sclerosis patients and whether they change over time and to determine whether physical function, psychological well-being, age and gender correlated with the use of different coping strategies. Amyotrophic lateral sclerosis is a fatal disease with impact on both physical function and psychological well-being. Different coping strategies are used to manage symptoms and disease progression, but knowledge about coping in newly diagnosed amyotrophic lateral sclerosis patients is scarce. This was a prospective study with a longitudinal and descriptive design. A total of 33 patients were included and evaluation was made at two time points, one to three months and six months after diagnosis. Patients were asked to complete the Motor Neuron Disease Coping Scale and the Hospital Anxiety and Depression Scale. Physical function was estimated using the revised Amyotrophic Lateral Sclerosis Functional Rating Scale. The most commonly used strategies were support and independence. Avoidance/venting and information seeking were seldom used at both time points. The use of information seeking decreased between the two time points. Men did not differ from women, but patients ≤64 years used positive action more often than older patients. Amyotrophic Lateral Sclerosis Functional Rating Scale was positively correlated with positive action at time point 1, but not at time point 2. Patients' psychological well-being was correlated with the use of different coping strategies. Support and independence were the most used coping strategies, and the use of different strategies changed over time. Psychological well-being was correlated with different coping strategies in newly diagnosed amyotrophic lateral sclerosis patients. The knowledge about coping strategies in early stage of the disease may help the nurses to improve and develop the care and support for these patients. © 2014 John Wiley & Sons Ltd.

Fulani pastoralists in Nigeria lack adequate access to good quality veterinary services and often resort to treating their animals themselves. There are several negative aspects to this, including poor treatment outcomes, misuse of veterinary drugs and subsequent resistance, and further barriers to good relations between pastoralists and veterinary services. A participatory epidemiology survey was undertaken in Fulani communities, to examine their ability to diagnose and treat bovine diseases. Qualitative participatory epidemiology techniques including semi-structured interviews, ranking and participant and non-participant observations were used for data collection. Quantitative analysis to match Fulani disease descriptions to veterinary diseases was done by hierarchical clustering and multi-dimensional scaling. A concurrent parasitological survey for soil-transmitted parasites, trypanosomiasis and tick-borne diseases was undertaken to validate results. Fulani pastoralists displayed high levels of ethnoveterinary knowledge and good clinical diagnostic abilities. Diseases considered important by pastoralists included: hanta (CBPP); sammore (trypanosomiasis); boro (foot and mouth disease), gortowel (liver fluke) , dauda (parasitic gastro-enteritis with bloody diarrhoea) and susa (parasitic gastro-enteritis). The parasitology survey supported the participatory epidemiology results but also showed a high prevalence of tick-borne diseases that were not mentioned by pastoralists in this study. The use of " hanta " to describe CBPP is important as the accepted translation is liver-fluke ( hanta is the Hausa word for liver). Gortowel and dauda , two previously undescribed Fulfulde disease names have now been matched to liver fluke and PGE with bloody diarrhoea. Fulani showed low levels of bovine veterinary knowledge with mostly incorrect veterinary drugs chosen for treatment. Levels of ethno- and bio-veterinary knowledge and their application within pastoralist livestock healthcare practices are discussed.

To determine the attitudes, knowledge, and self-care practices in patients with heart failure (HF) in Primary Care, as well as to identify factors associated with better self-care. Cross-sectional and multicentre study. Primary Care. Subjects over 18 years old with HF diagnosis, attended in 10 Primary Health Care Centres in the Metropolitan Area of Barcelona. Self-care was measured using the European Heart Failure Self-Care Behaviour Scale. Sociodemographic and clinical characteristics, tests on attitudes (Self-efficacy Managing Chronic Disease Scale), knowledge (Patient Knowledge Questionnaire), level of autonomy (Barthel), and anxiety and depression screening (Goldberg Test), were also gathered in an interview. A multivariate mixed model stratified by centre was used to analyse the adjusted association of covariates with self-care. A total of 295 subjects (77.6%) agreed to participate, with a mean age of 75.6 years (SD: 11), 56.6% women, and 62% with no primary education. The mean self-care score was 28.65 (SD: 8.22), with 25% of patients scoring lower than 21 points. In the final stratified multivariate model (n=282; R 2 conditional=0.3382), better self-care was associated with higher knowledge (coefficient, 95% confidence interval: -1.37; -1.85 to -0.90), and coronary heart disease diagnosis (-2.41; -4.36: -0.46). Self-care was moderate. The correlation of better self-care with higher knowledge highlights the opportunity to implement strategies to improve self-care, which should consider the characteristics of heart failure patients attended in Primary Care.

The Taiwan government currently promotes a case management approach to tuberculosis (TB) treatment to address the growing number of TB and multiple drug-resistant TB cases in Taiwan. The approach aims to improve medical follow-up and monitor quality of care. The efficacy of this case management approach has yet to be evaluated. The current study was designed to evaluate the effect of individualized case manager counseling on TB patient disease knowledge, attitudes, and behavioral intention. This study employed a one-group pretest-posttest quasi-experimental design. Participants first answered an initial questionnaire survey including three structured scales that addressed, respectively, the facets of disease knowledge, attitudes, and behavioral intention. TB case managers then delivered two- stage counseling to participants based on assessed individual needs and outstanding issues identified in questionnaire answers. A second questionnaire survey was administered 30~42 days after the intervention. Data on a total of 96 TB patients were collected. Key study findings were (1) individualized counseling significantly improved TB patient disease knowledge (p < .001) and (2) TB patient attitudes correlated significantly and positively with behavior intention (p < .001). Individualized counseling provided during the early stages of TB helps elevate patient awareness of the importance of treatment, enhances compliance and increases the cure rate.

Coronary heart disease (CHD) is the most prevalent type of cardiac disease among adults worldwide, including those in Singapore. Most of its risk factors, such as smoking, physical inactivity and high blood pressure, are preventable. mHealth has improved in the last decade, showing promising results in chronic disease prevention and health promotion worldwide. Our aim was to develop and examine the effect of a 4-week Smartphone-Based Coronary Heart Disease Prevention (SBCHDP) programme in improving awareness and knowledge of CHD, perceived stress as well as cardiac-related lifestyle behaviours in the working population of Singapore. The smartphone app "Care4Heart" was developed as the main component of the programme. App content was reviewed and validated by a panel of experts, including two cardiologists and two experienced cardiology-trained nurses. A pilot randomised controlled trial was conducted. Eighty working people were recruited and randomised to either the intervention group (n = 40) or the control group (n = 40). The intervention group underwent a 4-week SBCHDP programme, whereas the control group were offered health promotion websites only. The participants' CHD knowledge, perceived stress and behavioural risk factors were measured at baseline and on the 4th week using the Heart Disease Fact Questionnaire-2, Perceived Stress Scale, and Behavioural Risk Factor Surveillance System. After the SBCHDP programme, participants in the intervention group had a better awareness of CHD being the second leading cause of death in Singapore (X 2 = 6.486, p = 0.039), a better overall CHD knowledge level (t = 3.171, p = 0.002), and better behaviour concerning blood cholesterol control (X 2 = 4.54, p = 0.033) than participants in the control group. This pilot study partially confirmed the positive effects of the SBCHDP programme in improving awareness and knowledge of CHD among the working population. Due to the small sample size and short follow-up period, this study was underpowered to detect significant differences between groups. A full-scale longitudinal study is required in the future to confirm the effectiveness of the SBCHDP programme.
Frontotemporal neural systems supporting semantic processing in Alzheimer's disease.

We hypothesized that semantic memory for object concepts involves both representations of visual feature knowledge in modality-specific association cortex and heteromodal regions that are important for integrating and organizing this semantic knowledge so that it can be used in a flexible, contextually appropriate manner. We examined this hypothesis in an fMRI study of mild Alzheimer's disease (AD). Participants were presented with pairs of printed words and asked whether the words matched on a given visual-perceptual feature (e.g., guitar, violin: SHAPE). The stimuli probed natural kinds and manufactured objects, and the judgments involved shape or color. We found activation of bilateral ventral temporal cortex and left dorsolateral prefrontal cortex during semantic judgments, with AD patients showing less activation of these regions than healthy seniors. Moreover, AD patients showed less ventral temporal activation than did healthy seniors for manufactured objects, but not for natural kinds. We also used diffusion-weighted MRI of white matter to examine fractional anisotropy (FA). Patients with AD showed significantly reduced FA in the superior longitudinal fasciculus and inferior frontal-occipital fasciculus, which carry projections linking temporal and frontal regions of this semantic network. Our results are consistent with the hypothesis that semantic memory is supported in part by a large-scale neural network involving modality-specific association cortex, heteromodal association cortex, and projections between these regions. The semantic deficit in AD thus arises from gray matter disease that affects the representation of feature knowledge and processing its content, as well as white matter disease that interrupts the integrated functioning of this large-scale network.

Background Failure to detect a disease agent or vector where it actually occurs constitutes a serious drawback in epidemiology. In the pervasive situation where no sampling technique is perfect, the explicit analytical treatment of detection failure becomes a key step in the estimation of epidemiological parameters. We illustrate this approach with a study of Attalea palm tree infestation by Rhodnius spp. (Triatominae), the most important vectors of Chagas disease (CD) in northern South America. Methodology/Principal Findings The probability of detecting triatomines in infested palms is estimated by repeatedly sampling each palm. This knowledge is used to derive an unbiased estimate of the biologically relevant probability of palm infestation. We combine maximum-likelihood analysis and information-theoretic model selection to test the relationships between environmental covariates and infestation of 298 Amazonian palm trees over three spatial scales: region within Amazonia, landscape, and individual palm. Palm infestation estimates are high (40–60%) across regions, and well above the observed infestation rate (24%). Detection probability is higher (∼0.55 on average) in the richest-soil region than elsewhere (∼0.08). Infestation estimates are similar in forest and rural areas, but lower in urban landscapes. Finally, individual palm covariates (accumulated organic matter and stem height) explain most of infestation rate variation. Conclusions/Significance Individual palm attributes appear as key drivers of infestation, suggesting that CD surveillance must incorporate local-scale knowledge and that peridomestic palm tree management might help lower transmission risk. Vector populations are probably denser in rich-soil sub-regions, where CD prevalence tends to be higher; this suggests a target for research on broad-scale risk mapping. Landscape-scale effects indicate that palm triatomine populations can endure deforestation in rural areas, but become rarer in heavily disturbed urban settings. Our methodological approach has wide application in infectious disease research; by improving eco-epidemiological parameter estimation, it can also significantly strengthen vector surveillance-control strategies.

Despite a significant civilization advancement, parasitic diseases still pose a serious diagnostic and therapeutic problem. Children's susceptibility to these infections stems from their immature immune system and lack of basic hygiene routines. The objective of the study was to evaluate the level of knowledge which parents of preschool children's possess about parasitic diseases in their children's environment. The study was carried out in the group of 151 parents of preschool children living both in the city and in the country. The survey was carried out by means of a diagnostic poll with the application of a self-designed research questionnaire. To make the evaluation even more objective, a special scale was created in which parents could score points for their answers (0 - wrong answer, 1 - correct answer). The total number of points ranging from 0 to 9 indicated an unsatisfactory level of knowledge, from 10 to 13 - satisfactory level, from 14 to 16 - good level and from 17 to 20 - very good level of parents' awareness. The results of the study reveal that the level of parents' knowledge about parasitic diseases is only satisfactory. A statistically significant relationship was observed between the variables such as education and sex. The higher education, the higher level of knowledge. Moreover, women were more knowledgeable in the field of parasitic diseases than men were. Financial status of the family did not influence the level of parents' awareness. Well-planned educational programmes might have a positive influence on developing proper hygiene routines in families, which, in turn, will limit the risk of spreading parasitoses in the population of children.
Exploring the role of small-scale livestock keepers for national biosecurity-The pig case.
Correia-Gomes, Carla; Henry, Madeleine K; Auty, Harriet K; Gunn, George J
2017-09-15
Small-scale keepers are less likely to engage with production organisations and may therefore be less aware of legislation, rules and biosecurity practices which are implemented in the livestock sector. Their role in the transmission of endemic and exotic diseases is not well studied, but is believed to be important. The authors use small-scale pig keepers in Scotland as an example of how important small-scale livestock keepers might be for national biosecurity. In Scotland more than two thirds of pig producers report that they keep less than 10 pigs, meaning that biosecurity practices and pig health status on a substantial number of holdings are largely unknown; it is considered important to fill this knowledge gap. A questionnaire was designed and implemented in order to gather some of this information. The questionnaire comprised a total of 37 questions divided into seven sections (location of the enterprise, interest in pigs, details about the pig enterprise, marketing of pigs, transport of pigs, pig husbandry, and pig health/biosecurity). Over 610 questionnaires were sent through the post and the questionnaire was also available online. The questionnaire was implemented from June to October 2013 and 135 questionnaires were returned by target respondents. The responses for each question are discussed in detail in this paper. Overall, our results suggest that the level of disease identified by small-scale pig keepers is low but the majority of the small-scale pig keepers are mixed farms, with associated increased risk for disease transmission between species. Almost all respondents implemented at least one biosecurity measure, although the measures taken were not comprehensive in the majority of cases. Overall as interaction between small-scale keepers and commercial producers exists in Scotland the former can pose a risk for commercial production. This investigation fills gaps in knowledge which will allow industry stakeholders and policy makers to adapt their current disease programmes and contingency plans to the reality of small-scale pig-keeping enterprises' health and biosecurity status. We predict that some conclusions from this work will be relevant to countries with similar pig production systems and importantly some of these findings will relate to small-scale producers in other livestock sectors.

The safety of milk and dairy products has always been one of the focuses of consumers, the food industry and regulatory agencies. The purpose of this study was to gain insight into the food safety knowledge, attitudes and behavior of dairy plant workers. A cross-sectional survey was performed between May and August 2015 in three dairy plants in Beijing, northern China. A total of 194 dairy plant workers were interviewed to collect information on food safety knowledge, attitudes and self-reported behavior. The 194 dairy plant workers interviewed showed a sufficient level of knowledge (mean score 34 on a scale from 0-58), perfect attitudes (mean score 17 on a scale from 0-18), and perfect behavior (mean score 38 on a scale from 8-40). Only 39% of workers correctly determined specific pathogens or diseases that could be conveyed through milk and dairy products. 24% of workers knew the correct method of washing hands. A significant positive association was observed between attitudes and knowledge ( p < 0.001) as well as behavior ( p < 0.01). Education level was positively and significantly associated with food safety knowledge, attitudes, and behavior ( p < 0.05). Workers in dairy enterprises in northern China have relatively low levels of knowledge, yet satisfactory attitudes and behavior. The knowledge of microbial food hazards and hand hygiene remains an issue that needs to be emphasized in future training programs. Education level is a determinant of attitudes and behavior with regard to the proper handling of milk and dairy products.

Objective. To design an educational game that will increase third-year professional pharmacy students' knowledge of diabetes mellitus disease management and to evaluate their perceived value of the game. Methods. Faculty members created an innovative educational game, the diabetes escape room. An authentic escape room gaming environment was established through the use of a locked room, an escape time limit, and game rules within which student teams completed complex puzzles focused on diabetes disease management. To evaluate the impact, students completed a pre-test and post-test to measure the knowledge they've gained and a perception survey to identify moderating factors that could help instructors improve the game's effectiveness and utility. Results. Students showed statistically significant increases in knowledge after completion of the game. A one-sample t -test indicated that students' mean perception was statistically significantly higher than the mean value of the evaluation scale. This statically significant result proved that this gaming act offers a potential instructional benefit beyond its novelty. Conclusion. The diabetes escape room proved to be a valuable educational game that increased students' knowledge of diabetes mellitus disease management and showed a positive perceived overall value by student participants.

The annual incidence of illness related to food consumption continues to present a challenge to environmental health management. A significant fraction of cases have been attributed to consumption of food in restaurants, and as the number of meals eaten away from the home continues to rise, the potential for large-scale foodborne-disease outbreaks will continue to increase. Food handlers in retail establishments contribute to the incidence of foodborne disease; therefore, it is essential that workers and management staff have a thorough understanding of safe food practices. Since the training, certification, and experience of food service managers vary greatly, it is also likely that managers' knowledge base may differ. In the study reported here, restaurant managers were administered a survey designed to measure their understanding of basic food safety principles. The sources of training, certification, and experience were found to significantly affect the level of food safety knowledge; however, increased hours of training did not increase knowledge. In addition, the time lapsed since training did not significantly affect the level of knowledge.

The aim of this study was to assess the awareness of periodontal disease, its influence on general health, and attitude toward periodontal disease management among medical faculty in Guntur district. In this cross-sectional study, 150 medical faculty members from different specialties in Guntur district were included in the study. A self-administered questionnaire was prepared based on knowledge, attitude, and practice surveys to assess the awareness of periodontal disease and its management. Majority of the study participants (82%) had a previous dental visit. Only 31.3% believed that plaque is the major cause for periodontal disease. 56.7% responded that the relation between periodontal disease and systemic diseases is bidirectional. Only 39.3% were aware that periodontal disease is a risk factor for preterm low-birth weight infants. 52.6% of the medical faculty thought that scaling causes loss of enamel. 54.7% were aware that light amplification by stimulated emission of radiation is used in the periodontal treatment. Medical professionals who visited specialist in their previous dental visit obtained mean periodontal score (5.35 ± 1.686) greater than those who had visited general dentist and the difference is statistically significant (0.024). This study clearly demonstrates that medical practitioners had fair knowledge about various aspects of periodontal disease. This was particularly evident among those who have had a previous visit to a dentist. It was also found that young professionals with limited experience in the profession had better knowledge.

Patient education in connection with hip replacement is intended to prepare patients for surgery, discharge and postoperative recovery. Patients experience symptoms and emotions due to disease or upcoming surgery which can affect how their knowledge expectations are fulfilled. To describe the differences between received and expected knowledge in patients undergoing elective hip replacement in three Nordic countries, and to analyse how these differences are related to patients' characteristics, preoperative symptoms and emotions. A descriptive, prospective survey with two data collection points; before admission and at hospital discharge after surgery. Two Finnish, three Icelandic and two Swedish hospitals. The population consisted of patients on a waiting list for hip replacement. Of the consecutively included patients, 320 answered questionnaires both before admission and at discharge and were included in the study. The mean age of the patients was 64 years, and 55% were women. Structured questionnaires were used; the knowledge expectations of hospital patients scale and self-reported scales for symptoms and emotions before admission and received knowledge of hospital patients scale at discharge. Fulfilment of knowledge expectation was assessed by calculating the difference between received and expected knowledge with a paired sample t-test. A multiple stepwise regression model was used to explain the variance of fulfilled knowledge expectations. Patients expected more knowledge than they received (p<0.001) and 77% of them had unfulfilled knowledge expectations. Patients with a higher level of education were more likely to have unfulfilled knowledge expectations. A higher level of education was also related to a greater difference between received and expected knowledge. The difference was more correlated with patients' emotions than their symptoms. A depressive state was the major predictor of the variance in the difference between received and expected knowledge. In order to better support patients by education it is necessary to assess their emotional state, educational level and knowledge expectations before surgery. Copyright © 2014 Elsevier Ltd.

Heart failure is a complex disease with poor outcome. This complexity may prevent care providers from covering all aspects of care. This could not only be relevant for individual patient care, but also for care organisation. Disease management programmes applying a multidisciplinary approach are recommended to improve heart failure care. However, there is a scarcity of research considering how disease management programme perform, in what form they should be offered, and what care and support patients and care providers would benefit most. Therefore, the Improving kNowledge Transfer to Efficaciously Raise the level of Contemporary Treatment in Heart Failure (INTERACT-in-HF) study aims to explore the current processes of heart failure care and to identify factors that may facilitate and factors that may hamper heart failure care and guideline adherence. Within a cross-sectional mixed method design in three regions of the North-West part of Europe, patients (n = 88) and their care providers (n = 59) were interviewed. Prior to the in-depth interviews, patients were asked to complete three questionnaires: The Dutch Heart Failure Knowledge scale, The European Heart Failure Self-care Behaviour Scale and The global health status and social economic status. In parallel, retrospective data based on records from these (n = 88) and additional patients (n = 82) are reviewed. All interviews were audiotaped and transcribed verbatim for analysis.

Reasons for low participation of ethnic minorities in genetic studies are multifactorial and often poorly understood. Based on published literature, participation in genetic testing is low among Black African immigrants/refugees although they are purported to bear disproportionate disease burden. Thus, research involving Black African immigrant/refugee populations that examine their perspectives on participating in genetic studies is needed. This report examines and describes the knowledge of medical genetics, group-based medical mistrust, and future expectations of genetic research and the influence of these measures on the perceived disadvantages of genetic testing among Black African immigrants/refugees. Using a cross-sectional survey design, a nonprobability sample (n = 212) of Black African immigrants/refugees was administered a questionnaire. Participants ranged in age from 18 to 61 years (mean = 38.91, SD = 9.78). The questionnaire consisted of 5 instruments: (a) sociodemographic characteristics, (b) Knowledge of Medical Genetics scale, (c) Group-Based Medical Mistrust Scale, (d) Future Expectations/Anticipated Consequences of Genetics Research scale, and (e) Perceived Disadvantages of Genetic Testing scale. Participants were concerned that genetic research may result in scientists 'playing God,' interfering with the natural order of life. In multivariate analyses, the perceived disadvantages of genetic testing increased as medical mistrust and anticipated negative impacts of genetic testing increased. Increase in genetic knowledge contributed to a decrease in perceived disadvantages. Our findings suggest that recruitment of Black African immigrants/refugees in genetic studies should address potential low knowledge of genetics, concerns about medical mistrust, the expectations/anticipated consequences of genetic research, and the perceived disadvantages of genetic testing.

Knowledge of factors influencing health-related quality of life (HRQL) in people with amyotrophic lateral sclerosis (ALS) is important because some factors might be amenable to intervention. The aim was to describe and explore the effects of disease severity, fatigue, anxiety, depression, frequency of social and lifestyle activities, coping capacity and mechanical ventilator use on HRQL in people with ALS. Sixty people with ALS were enrolled in this cross-sectional study. Data were collected with questionnaires during home visits. The Sickness Impact Profile and the EuroQol Visual Analogue Scale were used to assess HRQL. Multivariate regression analyses explored associations between HRQL and independent factors. Low frequency of social and lifestyle activities, and severe disease, were associated with worse HRQL, explaining 57% of total variance in the Sickness Impact Profile physical score. Severe disease, weak coping capacity and anxiety and/or depression were associated with worse HRQL, explaining 33% of total variance in Sickness Impact Profile psychosocial score. Fatigue and mechanical ventilator use were associated with worse HRQL, explaining 17% of variance in the EuroQol Visual Analogue Scale. Knowledge and understanding of how frequency of social and lifestyle activities, disease severity, coping capacity, anxiety and/or depression, fatigue and ventilator use contribute to and predict self-rated HRQL can optimize person-centred care and support.

Patients with extensive ulcerative colitis or Crohn's disease of the colon have an increased risk of colon cancer and require colonoscopic surveillance. In this study, we assessed individual self-efficacy (SE) to estimate the probability of adherence to surveillance colonoscopies. Three hundred seventy-eight patients with ulcerative colitis or Crohn's disease of the colon for at least 7 years and with at least one third of the colon involved participated in this cross-sectional questionnaire study performed at 3 tertiary referral inflammatory bowel disease clinics. Medical charts were abstracted for demographic and clinical variables. The questionnaire contained a group of items assessing SE for undergoing colonoscopy. We validated our 20-question SE scale and used 8 of the items that highlighted scheduling, preparation, and postprocedure recovery, to develop 2 shorter SE scales. All 3 scales were reliable with Cronbach's α ranging from 0.845 to 0.905 and correlated with chart-documented adherence to surveillance colonoscopy (P < 0.001). We then developed logistic regression models to predict adherence to surveillance colonoscopy using each scale separately along with other key variables (i.e., disease location, knowledge of correct adherence intervals, and information sources of patients consulted regarding Crohn's disease and ulcerative colitis) and demonstrated model accuracy up to 74%. SE, as measured by our validated scales, correlates with chart-adherence to surveillance colonoscopy. Our adherence model, which includes SE, predicts adherence with 74% certainty. An 8-item validated clinical questionnaire can be administered to assess whether patients in this population may require further intervention for adherence.

Previously we generated a chronic obstructive pulmonary disease (COPD) specific knowledge base (http://www.copdknowledgebase.eu) from clinical and experimental data, text-mining results and public databases. This knowledge base allowed the retrieval of specific molecular networks together with integrated clinical and experimental data. The COPDKB has now been extended to integrate over 40 public data sources on functional interaction (e.g. signal transduction, transcriptional regulation, protein-protein interaction, gene-disease association). In addition we integrated COPD-specific expression and co-morbidity networks connecting over 6 000 genes/proteins with physiological parameters and disease states. Three mathematical models describing different aspects of systemic effects of COPD were connected to clinical and experimental data. We have completely redesigned the technical architecture of the user interface and now provide html and web browser-based access and form-based searches. A network search enables the use of interconnecting information and the generation of disease-specific sub-networks from general knowledge. Integration with the Synergy-COPD Simulation Environment enables multi-scale integrated simulation of individual computational models while integration with a Clinical Decision Support System allows delivery into clinical practice. The COPD Knowledge Base is the only publicly available knowledge resource dedicated to COPD and combining genetic information with molecular, physiological and clinical data as well as mathematical modelling. Its integrated analysis functions provide overviews about clinical trends and connections while its semantically mapped content enables complex analysis approaches. We plan to further extend the COPDKB by offering it as a repository to publish and semantically integrate data from relevant clinical trials. The COPDKB is freely available after registration at http://www.copdknowledgebase.eu.

The present study was conducted to assess the awareness, knowledge, and risks of zoonotic diseases among livestock farmers in Punjab. 250 livestock farmers were selected randomly and interviewed with a pretested questionnaire, which contained both open and close ended questions on different aspects of zoonotic diseases, i.e., awareness, knowledge, risks, etc. Knowledge scorecard was developed, and each correct answer was awarded one mark, and each incorrect answer was given zero mark. Respondents were categorized into low (mean - ½ standard deviation [SD]), moderate (mean ± ½ SD), and high knowledge (Mean + ½ SD) category based on the mean and SD. The information about independent variables viz., age, education, and herd size were collected with the help of structured schedule and scales. The data were analyzed by ANOVA, and results were prepared to assess awareness, knowledge, and risks of zoonotic diseases and its relation with independent variables. Majority of the respondents had age up to 40 years (70%), had their qualification from primary to higher secondary level (77.6%), and had their herd size up to 10 animals (79.6%). About 51.2% and 54.0% respondents had the history of abortion and retained placenta, respectively, at their farms. The respondents not only disposed off the infected placenta (35.6%), aborted fetus (39.6%), or feces (56.4%) from a diarrheic animal but also gave intrauterine medication (23.2%) bare-handedly. About 3.6-69.6% respondents consumed uncooked or unpasteurized animal products. About 84.8%, 46.0%, 32.8%, 4.61%, and 92.4% of livestock farmers were aware of zoonotic nature of rabies, brucellosis, tuberculosis, anthrax, and bird flu, respectively. The 55.6%, 67.2%, 52.0%, 64.0%, and 51.2% respondents were aware of the transmission of zoonotic diseases to human being through contaminated milk, meat, air, feed, or through contact with infected animals, respectively. The transmission of rabies through dog bite (98.4%), need of post-exposure vaccination (96.8%), and annual vaccination of dogs (78%) were well-known facts but only 47.2% livestock owners were aware of the occurrence of abortion due to brucellosis and availability of prophylactic vaccine (67.6%) against it as a preventive measure. About 69.2% respondents belonged to low to medium knowledge level categories, whereas 30.8% respondents had high knowledge (p<0.05) regarding different aspects of zoonotic diseases. Age, education, and herd size had no significant effect on the knowledge level and awareness of farmers toward zoonotic diseases. Therefore, from the present study, it may be concluded that there is a need to create awareness and improve knowledge of livestock farmers toward zoonotic diseases for its effective containment in Punjab.

Thalassemia is a life-threatening blood disorder that has a high prevalence in Saudi Arabia despite the implementation of mandatory premarital testing and the availability of genetic counseling. This study aimed to assess college students' knowledge of thalassemia. A cross-sectional survey of a random sample of 920 senior students enrolled at King Abdulaziz University was conducted. A self-administered questionnaire was used to collect information about thalassemia and socio-demographic characteristics. Of the 920 students, 445 (48%) had ever heard of thalassemia. Despite the mandatory premarital testing for thalassemia, only 50% of married students stated having heard of the disease. The mean thalassemia knowledge score was 4.4 ± 2.2 out of a maximum of 12. Knowledge was significantly influenced by university faculty, gender, and education outside of Saudi Arabia. Those who had heard of thalassemia had misconceptions about the disease characteristics and pattern of inheritance such as associating thalassemia with low iron levels. A substantial proportion of the participants had a low knowledge of thalassemia. This lack of awareness requires a reassessment of the goals and success of the premarital testing program, including the genetic counseling services, and also indicates the importance of emphasizing thalassemia in school curricula and promoting and scaling up existing thalassemia campaigns in the region.

There is a large population at high risk for diabetes in China, and there has been a dramatic increase in the incidence of diabetes in the country over the past 30 years. Interventions targeting the individual risk factors of diabetes can effectively prevent diabetes; these include factors such as an unhealthy diet, lack of physical activity, overweight, and obesity, among others. Evaluation of related knowledge, attitudes, and behaviors before and after intervention using appropriate scales can measure population demands and the effectiveness of interventions. Scientificity and practicability are basic requirements of scale development. The theoretical basis and measuring items of a scale should be consistent with the theory of behavior change and should measure the content of interventions in a standardized and detailed manner to produce good validity, reliability, and acceptability. The scale of knowledge, attitude, and behavior of lifestyle intervention in a diabetes high-risk population is a tool for demand evaluation and effect evaluation of lifestyle intervention that has good validity and reliability. Established by the National Center for Chronic and Noncommunicable Disease Control and Prevention, its use can help to decrease the Chinese population at high risk for diabetes through targeted and scientifically sound lifestyle interventions. Future development of intervention evaluation scales for useing in high-risk populations should consider new factors and characteristics of the different populations, to develop new scales and modify or simplify existing ones, as well as to extend the measurement dimensions to barriers and supporting environment for behaviors change.

To develop a mHealth programme, entitled 'Care4Heart' for the working population in Singapore and thereafter examine its feasibility and effectiveness in increasing the awareness and knowledge of coronary heart disease and improving their heart-related lifestyle. Teaching and encouraging the working population to adopt a healthier lifestyle could result in preventing and/or decreasing the incidence of coronary heart disease among this population. The use of mobile application (app) is the next logical wave of healthcare support tools to prevent and manage chronic diseases like coronary heart disease. A quasi-experimental longitudinal study design. The study will be conducted in a tertiary university in Singapore. A non-probability, quota sampling of 200 participants will be recruited including 100 academic and research staff, 50 administrative staff and 50 support staff and business owners. Once consent is obtained, the newly developed mobile app will be installed onto the participants' smartphones and a well-trained research assistant will brief the participant on the use of the app. The main outcomes will be measured using the survey questionnaires: Awareness of coronary heart disease, Heart Disease Fact Questionnaire-2, Behavioural Risk Factor Surveillance System and Perceived Stress Scale. Data will be collected at baseline and at the 4th week and 6th month thereafter. If this project is successful, Care4Heart - a mHealth and novel prevention educational programme for the working population in Singapore - can be used to promote knowledge and positive heart-related lifestyle changes to prevent coronary heart disease. © 2015 John Wiley & Sons Ltd.

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

To assess motivation and knowledge domains of medication adherence intention, and to determine their predictors in an ambulatory setting. We conducted a cross-sectional survey study among patients attending a chronic disease clinic at the Family and Community Medicine Department, Prince Sultan Military Medical City, Riyadh, Kingdom of Saudi Arabia between June and September 2010. Adherence intention was assessed using Modified Morisky Scale. Predictors of low motivation and/or knowledge were determined using logistic regression models. A total of 347 patients were interviewed during the study duration. Most patients (75.5%) had 2 or more chronic diseases with an average of 6.3 +/- 2.3 medications, and 6.5 +/- 2.9 pills per prescription. The frequency of adherence intention was low (4.6%), variable (37.2%), and high (58.2%). In multivariate logistic regression analysis, younger age and having asthma were significantly associated with low motivation, while male gender, single status, and not having hypertension were significantly associated with low knowledge. Single status was the only independent predictor of low adherence intention. In a population with multiple chronic diseases and high illiteracy rate, more than 40% had low/variable intention to adhere to prescribed medications. Identifying predictors of this group may help in providing group-specific interventional programs.
Computation as the mechanistic bridge between precision medicine and systems therapeutics.

Over the past 50 years, like molecular cell biology, medicine and pharmacology have been driven by a reductionist approach.

Over the past 50 years, like molecular cell biology, medicine and pharmacology have been driven by a reductionist approach. The focus on individual genes and cellular components as disease loci and drug targets has been a necessary step in understanding the basic mechanisms underlying tissue/organ physiology and drug action. Recent progress in genomics and proteomics, as well as advances in other technologies that enable large-scale data gathering and computational approaches, is providing new knowledge of both normal and disease states. Systems-biology approaches enable integration of knowledge from different types of data for precision medicine and systems therapeutics. In this review, we describe recent studies that contribute to these emerging fields and discuss how together these fields can lead to a mechanism-based therapy for individual patients. PMID:23212109

The presence of expanded poly-glutamine (polyQ) repeats in proteins is directly linked to the pathogenesis of several neurodegenerative diseases, including Huntington’s disease. However, the molecular and structural basis underlying the increased toxicity of aggregates formed by proteins containing expanded polyQ repeats remain poorly understood, in part due to the size and morphological heterogeneity of the aggregates they form in vitro. To address this knowledge gap and technical limitations, we investigated the structural, mechanical and morphological properties of fibrillar aggregates at the single molecule and nanometer scale using the first exon of the Huntingtin protein as a model system (Exon1). Our findings demonstrate a direct correlation of the morphological and mechanical properties of Exon1 aggregates with their structural organization at the single aggregate and nanometric scale and provide novel insights into the molecular and structural basis of Huntingtin Exon1 aggregation and toxicity.

Development and pilot testing of a disease management program for low literacy patients with heart failure. Randomized trials have shown that disease management programs can reduce hospitalizations and improve symptoms for patients with congestive heart failure. We sought to create and pilot test such a program for patients with low literacy skills. We used focus groups and individual cognitive response interviews (CRIs) to develop an educational booklet for low literacy patients with heart failure. We incorporated the booklet into a disease management intervention that also included an initial individualized 1-h educational session and scheduled supportive phone calls that were tapered over 6 weeks. We then conducted a 3-month before-after study on patients with low literacy skills (<9th grade literacy level) in a university internal medicine clinic to test the acceptability and efficacy of our program. Outcomes of interest included heart failure-related knowledge, self-care behavior and heart failure-related symptoms measured on the Minnesota Living with Heart Failure (MLwHF) scale. Twenty-five patients were enrolled and 23 (92%) completed 3-month follow-up. Mean age was 60 years (range 35-74), 60% were men, 60% were African-American, and 74% had household income under $15,000 per year. The median reading level was fifth grade with 32% reading at or below the third grade level. Mean knowledge score at baseline was 67% and did not improve after the intervention. The proportion of patients reporting weighing themselves daily increased from 32% at baseline to 100% at 12 weeks. Mean improvement on the MLwHF scale was 9.9 points over the 3-month trial (95% CI: 0.5, 19.2), which corresponds to an improvement in one class on the New York Heart Association heart failure scale. A heart failure disease management program designed specifically for patients with low literacy skills is acceptable and is associated with improvement in self-care behavior and heart failure related symptoms.
Increasing self-knowledge: Utilizing tele-coaching for patients with congestive heart failure.
Rosen, Daniel; Berrios-Thomas, Saskia; Engel, Rafael J

The objective was to assess self-care knowledge changes with dually eligible Medicare and Medicaid patients diagnosed with congestive heart failure (CHF), who received a telecoaching protocol integrating symptom monitoring with face-to-face video chat with a social worker. We recruited 45 patients with CHF from a regional managed care organization. Sessions via a Health Insurance Portability and Accountability Act-compliant tablet-based platform focused on educational information designed to improve patient self-care. Social workers administered the 13-item Member Confidence Measure (MCM) at baseline and at a 30-day follow-up period. Scores were recorded to measure differences in patients' understanding of CHF and related symptoms, their knowledge of the disease, and the behaviors necessary to prevent their symptoms from getting worse. Over the 30-day period, scores significantly (p < .01) increased on the total scale score and specific confidence measure subscales (symptom recognition, medication adherence, medical attention, healthy choices, and safety). Gender, race, and age were unrelated to these improvements. In addition, effect sizes for the sub-scales ranged from .54 to 1.08; the effect size of the intervention as expressed by the total scale score was 1.12. Overall, patients increased knowledge over a 30-day period. Tele-coaching by social workers holds promise as a feasible model for health education for high-risk populations.

People with Parkinsonism (PWP) in residential facilities are usually elderly, cognitively impaired, physically disabled with poor quality of life and a high mortality rate. This paper aims to determine if the care of PWP in residential facilities could be improved by addressing staff knowledge on Parkinson related issues. A curriculum based on the Victorian Comprehensive Parkinson Program (VCPP) was developed and delivered to 118 staff members in 9 facilities across Melbourne. Measures of staff knowledge were undertaken at baseline, 1, 3 and 12 months. Data from a total of 49 residents were used in the analysis. Measures were taken at baseline, 1, 3 and 12 months included dementia screen (MMSE), geriatric depression scale (GDS), quality of life (PDQ39), fatigue (PDFS16), monthly falls diary, Unified Parkinson Disease Rating Scale (I,II,III) Hoehn & Yahr scale (H&Y) and resident/family questionnaire (RFQ) which focused on quality of care provision. It was found that the staff knowledge assessment scores (max = 37) significantly improved post education (P < 0.01) from baseline mean (11.1) and were maintained to 12 months mean (29.0). The residents group improved significantly for all measures at 1 month and these improvements were maintained up to 12 months (except for UPDRS III). This study demonstrated how a simple intervention, resulting in improved staff knowledge, produced a significant and clinically meaningful improvement in the care of PWP.
A study of EMR-based medical knowledge network and its applications.

Electronic medical records (EMRs) contain an amount of medical knowledge which can be used for clinical decision support. We attempt to integrate this medical knowledge into a complex network, and then implement a diagnosis model based on this network. The dataset of our study contains 992 records which are uniformly sampled from different departments of the hospital. In order to integrate the knowledge of these records, an EMR-based medical knowledge network (EMKN) is constructed. This network takes medical entities as nodes, and co-occurrence relationships between the two entities as edges. Selected properties of this network are analyzed. To make use of this network, a basic diagnosis model is implemented. Seven hundred records are randomly selected to re-construct the network, and the remaining 292 records are used as test records. The vector space model is applied to illustrate the relationships between diseases and symptoms. Because there may exist more than one actual disease in a record, the recall rate of the first ten results, and the average precision are adopted as evaluation measures. Compared with a random network of the same size, this network has a similar average length but a much higher clustering coefficient. Additionally, it can be observed that there are direct correlations between the community structure and the real department classes in the hospital. For the diagnosis model, the vector space model using disease as a base obtains the best result. At least one accurate disease can be obtained in 73.27% of the records in the first ten results. We constructed an EMR-based medical knowledge network by extracting the medical entities. This network has the small-world and scale-free properties. Moreover, the community structure showed that entities in the same department have a tendency to be self-aggregated. Based on this network, a diagnosis model was proposed. This model uses only the symptoms as inputs and is not restricted to a specific disease. The experiments conducted demonstrated that EMKN is a simple and universal technique to integrate different medical knowledge from EMRs, and can be used for clinical decision support.

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

The correlation of phenotypic outcomes with genetic variation and environmental factors is a core pursuit in biology and biomedicine. Numerous challenges impede our progress: patient phenotypes may not match known diseases, candidate variants may be in genes that have not been characterized, model organisms may not recapitulate human or veterinary diseases, filling evolutionary gaps is difficult, and many resources must be queried to find potentially significant genotype–phenotype associations. Non-human organisms have proven instrumental in revealing biological mechanisms. Advanced informatics tools can identify phenotypically relevant disease models in research and diagnostic contexts. Large-scale integration of model organism and clinical research data can provide a breadth of knowledge not available from individual sources and can provide contextualization of data back to these sources. The Monarch Initiative (monarchinitiative.org) is a collaborative, open science effort that aims to semantically integrate genotype–phenotype data from many species and sources in order to support precision medicine, disease modeling, and mechanistic exploration. Our integrated knowledge graph, analytic tools, and web services enable diverse users to explore relationships between phenotypes and genotypes across species. PMID:27899636

Understanding infectious diseases such as influenza is an important element of health literacy. We present a fully validated knowledge instrument called the Assessment of Knowledge of Influenza (AKI) and use it to evaluate knowledge of influenza, with a focus on misconceptions, in Midwestern United States high-school students. A two-phase validation process was used. In phase 1, an initial factor structure was calculated based on 205 students of grades 9-12 at a rural school. In phase 2, one- and two-dimensional factor structures were analyzed from the perspectives of classical test theory and the Rasch model using structural equation modeling and principal components analysis (PCA) on Rasch residuals, respectively. Rasch knowledge measures were calculated for 410 students from 6 school districts in the Midwest, and misconceptions were verified through the χ 2 test. Eight items measured knowledge of flu transmission, and seven measured knowledge of flu management. While alpha reliability measures for the subscales were acceptable, Rasch person reliability measures and PCA on residuals advocated for a single-factor scale. Four misconceptions were found, which have not been previously documented in high-school students. The AKI is the first validated influenza knowledge assessment, and can be used by schools and health agencies to provide a quantitative measure of impact of interventions aimed at increasing understanding of influenza. This study also adds significantly to the literature on misconceptions about influenza in high-school students, a necessary step toward strategic development of educational interventions for these students.
Modern network science of neurological disorders.
Stam, Cornelis J
2014-10-01
Modern network science has revealed fundamental aspects of normal brain-network organization, such as small-world and scale-free patterns, hierarchical modularity, hubs and rich clubs. The next challenge is to use this knowledge to gain a better understanding of brain disease. Recent developments in the application of network science to conditions such as Alzheimer's disease, multiple sclerosis, traumatic brain injury and epilepsy have challenged the classical concept of neurological disorders being either 'local' or 'global', and have pointed to the overload and failure of hubs as a possible final common pathway in neurological disorders.
Advanced Parkinson's or "complex phase" Parkinson's disease? Re-evaluation is needed.
Titova, Nataliya; Martinez-Martin, Pablo; Katunina, Elena; Chaudhuri, K Ray
2017-12-01
Holistic management of Parkinson's disease, now recognised as a combined motor and nonmotor disorder, remains a key unmet need. Such management needs relatively accurate definition of the various stages of Parkinson's from early untreated to late palliative as each stage calls for personalised therapies. Management also needs to have a robust knowledge of the progression pattern and clinical heterogeneity of the presentation of Parkinson's which may manifest in a motor dominant or nonmotor dominant manner. The "advanced" stages of Parkinson's disease qualify for advanced treatments such as with continuous infusion or stereotactic surgery yet the concept of "advanced Parkinson's disease" (APD) remains controversial in spite of growing knowledge of the natural history of the motor syndrome of PD. Advanced PD is currently largely defined on the basis of consensus opinion and thus with several caveats. Nonmotor aspects of PD may also reflect advancing course of the disorder, so far not reflected in usual scale based assessments which are largely focussed on motor symptoms. In this paper, we discuss the problems with current definitions of "advanced" PD and also propose the term "complex phase" Parkinson's disease as an alternative which takes into account a multimodal symptoms and biomarker based approach in addition to patient preference.
A pharma perspective on the systems medicine and pharmacology of inflammation.
Lahoz-Beneytez, Julio; Schnizler, Katrin; Eissing, Thomas
2015-02-01
Biological systems are complex and comprehend multiple scales of organisation. Hence, holistic approaches are necessary to capture the behaviour of these entities from the molecular and cellular to the whole organism level. This also applies to the understanding and treatment of different diseases. Traditional systems biology has been successful in describing different biological phenomena at the cellular level, but it still lacks of a holistic description of the multi-scale interactions within the body. The importance of the physiological context is of particular interest in inflammation. Regulatory agencies have urged the scientific community to increase the translational power of bio-medical research and it has been recognised that modelling and simulation could be a path to follow. Interestingly, in pharma R&D, modelling and simulation has been employed since a long time ago. Systems pharmacology, and particularly physiologically based pharmacokinetic/pharmacodynamic models, serve as a suitable framework to integrate the available and emerging knowledge at different levels of the drug development process. Systems medicine and pharmacology of inflammation will potentially benefit from this framework in order to better understand inflammatory diseases and to help to transfer the vast knowledge on the molecular and cellular level into a more physiological context. Ultimately, this may lead to reliable predictions of clinical outcomes such as disease progression or treatment efficacy, contributing thereby to a better care of patients.

A systematic review of the public's knowledge and understanding of Alzheimer's disease and dementia.
Cahill, Suzanne; Pierce, Maria; Werner, Perla; Darley, Andrew; Bobersky, Andrea
2015-01-01
This paper reports findings from a systematic review of the literature on the general public's knowledge and understanding of dementia/Alzheimer's disease. The key purpose of the review was to evaluate existing literature with specific attention paid to conceptual and methodological issues and to key findings. Over a 20-year period, 40 published articles satisfied the inclusion criteria. Only 4 of these were qualitative and 5 were cross-national. The review revealed a lack of consistency across studies regarding how knowledge was operationalized, approaches to sampling, response rates, and data collection instruments used including validated scales. A consistent finding across the vast majority of studies was the only fair to moderate knowledge and understanding the general public had. The most common misconception was that dementia was a normal part of aging and there was a lack of clarity about at which point normal age-related memory loss problems become severe enough to indicate dementia. Knowledge of dementia was found to be particularly poor among racial and ethnic minority groups where several myths about causes of dementia were found. Findings point to the need for more educational and advocacy programmes on dementia to be developed particularly in low-income to middle-income countries.

Integrative Systems Biology for Data Driven Knowledge Discovery
Greene, Casey S.; Troyanskaya, Olga G.
2015-01-01
Integrative systems biology is an approach that brings together diverse high throughput experiments and databases to gain new insights into biological processes or systems at molecular through physiological levels. These approaches rely on diverse high-throughput experimental techniques that generate heterogeneous data by assaying varying aspects of complex biological processes. Computational approaches are necessary to provide an integrative view of these experimental results and enable data-driven knowledge discovery. Hypotheses generated from these approaches can direct definitive molecular experiments in a cost effective manner. Using integrative systems biology approaches, we can leverage existing biological knowledge and large-scale data to improve our understanding of yet unknown components of a system of interest and how its malfunction leads to disease.

Long-term exposure to physical, chemical, ergonomic and psychosocial environmental factors may lead to occupational cardiovascular disease in metal industry employees. This study aimed to determine levels of knowledge levels regarding occupational and cardiovascular risk factors among metal industry employees. The study was conducted between 2nd and 6th June 2014 with the participation of 82 employees. All were working in a medium-sized workplace in the metal industry. Data were collected by means of a questionnaire, which included socio-demographic characteristics and occupational cardiovascular risk factors, and a scale developed by Arıkan et al. to measure awareness levels of risk factors for cardiovascular diseases (CARRF-KL). The mean age of employees was 39.97±8.44. Of the participants, 58.5% stated that they had knowledge on cardiac disease risk factors. The mean CARRF-KL score was found to be 18.65±4.04. The percentage of employees stating that they had no knowledge on the occupational risks for such diseases was 79.3%, while 19.5% stated that job stress caused cardiac diseases. One individual (1.2%) stated that one of the chemical solvents used in the working environment was a risk factor. Although awareness among metal industry employees of cardiovascular risk factors was above average, it was determined that they do not have adequate information on occupational risk factors. Prolonged and unprotected levels exposure to environmental factors constitute a risk for cardiovascular disease. This information is important for the development of preventive cardiology.

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

This study aims to evaluate association between Health related quality of lifeand disease state knowledge among hypertensive population of Pakistan. A cross sectional descriptive study was undertaken with a representative cohort of hypertension patients. Using prevalence based sampling technique, a total of 385 hypertensive patients were selected from two public hospitals of Quetta city, Pakistan. Hypertension Fact Questionnaire (HFQ) and European Quality of Life scale (EQ-5D) were used for data collection. Statistical Package for the Social Sciences 16.0 was used to compute descriptive analysis of patients' demographic and disease related information. Categorical variables were described as percentages while continuous variables were expressed as mean ± standard deviation (SD). Spearman's rho correlation was used to identify the association between study variables. The mean (SD) age of the patients was 39.02 (6.59), with 68.8% males (n=265). The mean (SD) duration of hypertension was 3.01 (0.93) years. Forty percent (n=154) had bachelor degree with 34.8% (n=134) working in private sector. Almost forty one percent (n=140) had monthly income of more than 15000 Pakistan rupees per month with 75.1% (n=289) having urban residency. The mean EQ-5D descriptive score (0.46±0.28) and EQ-VAS score (63.97±6.62) indicated lower HRQoL in our study participants. Mean knowledge score was 8.03 ± 0.42. Correlation coefficient between HRQoL and knowledge was 0.208 (p< 0.001), indicating a week positive association. Results of this study highlight hypertension knowledge to be weakly associated with HRQoL suggesting that imparting knowledge to patients do not necessarily improve HRQoL. More attention should be given to identify individualized factors affecting HRQoL.

Episodic and semantic processes are involved in temporality used in daily life. Episodic memory permits one to place an event on the time axis, while semantic memory makes us aware of the time segmentation and its symbolic representation. Memory of the knowledge connected to the passing of time is materialized on the calendar and can be seen symbolically on the dial of a clock. In AD, semantic memory processes are preserved longer than processes related to episodic memory. We wonder whether the specific field of knowledge about time is altered during AD. We validated a specific evaluation with a control group (354 healthy subjects). Then we applied this battery to assess AD patients to appreciate the feasibility of this tool for this population. We then compared 22 AD patients with a control group matched for age, sex and educational level. Our clinical scale of temporal semantic knowledge consists of four parts: (a) hour reading with a.m. and p.m. hours; (b) using a clock: 12 clock faces with the hour numbers already placed: the patient draws hour and minute hands for various hours; (c) temporal segmentation: exploration of the knowledge on daytime scale and of the calendar; (d) time duration estimation: calculate how long the interview has lasted after indicating the time of its beginning and its end, then the time between 10.40 to 12.00. While age and educational level had an influence on all the scores, in the two groups control and patients, gender did not. Temporal segmentation, independent of the cultural level, revealed the best acquired knowledge in our control population. All the scores differentiated patients from control subjects. The temporal semantic knowledge correlated with the AD severity seemed to be correlated with the attention, verbal comprehension, and some components of executive functions, but was not related to the clock drawing test result. Depression did not have any influence on this scale in our AD group. The temporal semantic knowledge clinical scale shows differential alterations, notably in hour reading and using a clock, and less in temporal segmentation. Temporal semantic knowledge is altered in AD. The diagnosis and follow-up of these alterations allow professionals and caregivers to consider adaptations of the patient's environment according to their needs. Copyright © 2013 L’Encéphale, Paris.

Women's under-representation in HIV and cardiovascular disease (CVD) research suggests a need for novel strategies to ensure robust representation of women in HIV-associated CVD research. To elicit perspectives on CVD research participation among a community-sample of women with or at risk for HIV, and to apply acquired insights toward the development of an evidence-based campaign empowering older women with HIV to participate in a large-scale CVD prevention trial. In a community-based setting, we surveyed 40 women with or at risk for HIV about factors which might facilitate or impede engagement in CVD research. We applied insights derived from these surveys into the development of the Follow YOUR Heart campaign, educating women about HIV-associated CVD and empowering them to learn more about a multi-site HIV-associated CVD prevention trial: REPRIEVE. Endorsed best methods for learning about a CVD research study included peer-to-peer communication (54%), provider communication (46%) and video-based communication (39%). Top endorsed non-monetary reasons for participating in research related to gaining information (63%) and helping others (47%). Top endorsed reasons for not participating related to lack of knowledge about studies (29%) and lack of request to participate (29%). Based on survey results, the REPRIEVE Follow YOUR Heart campaign was developed. Interwoven campaign components (print materials, video, web presence) offer provider-based information/knowledge, peer-to-peer communication, and empowerment to learn more. Campaign components reflect women's self-identified motivations for research participation - education and altruism. Investigation of factors influencing women's participation in HIV-associated CVD research may be usefully applied to develop evidence-based strategies for enhancing women's enrollment in disease-specific large-scale trials. If proven efficacious, such strategies may enhance conduct of large-scale research studies across disciplines.
Consumers' knowledge, understanding, and attitudes toward health claims on food labels.

The purpose of this study was to assess consumers' knowledge of current fiber recommendations and their attitudes, understanding, and awareness of health claims on breakfast cereal labels. An incidental sample of 241 respondents was drawn from four grocery stores of a local chain in Utah. Data were collected using a computerized interviewing system. The results suggested that consumers with higher education levels had a better understanding of diet-disease-related messages and a more positive attitude toward health messages on food labels. Knowledge of fiber was significantly correlated with positive attitudes toward health messages and understanding of health messages. Overall, attitudes toward placing diet-disease-related messages on food labels were positive. On a scale of 1 through 250, the mean score was 182.5 +/- 37.5 standard deviation (73%). Consumer knowledge of fiber was low. Out of 15 possible points, the mean score for fiber knowledge questions was 8.8 +/- 2.1 (59%). Consumers were more familiar with the role fiber may play in the prevention or treatment of certain diseases or conditions than with sources, classifications, and recommended intakes of fiber. Understanding of health messages was relatively low (45%). Whereas consumer attitudes toward health messages on food labels were positive, consumers (especially less-educated consumers) did not appear to understand the messages well. These results reiterate the concern for public policymakers to exercise caution and ensure that health messages on food labels are responsible and accurate. The results should also remind dietetic practitioners, who are the nutrition experts, of their continual role in providing and ensuring accurate nutrition education to the public.

Hypertension, dyslipidemia, and diabetes are established risk factors for cardiovascular disease (CVD) morbidity and mortality. In the past decade a general increase in CVD risk factors in the population aged 65 and older, along with suboptimal control rates, have occurred. In this descriptive, cross-sectional study, the authors describe the knowledge, attitudes, and practices (KAP) of Iranian females regarding risk factors for CVD, in an attempt to help with the development of strategies to control risk factors and CVD. Participants were 200 women ages 15-49 referred to health centers in Yazd, selected from four different centers. Data were gathered through a questionnaire consisting of demographics and questions related to KAP. The validity of the questionnaire was determined by a health education specialist, with its reliability determined by piloting and measuring the related Cronbach's alpha (Alpha = 0.720). Measuring knowledge of CVD on a scale of 0-20, the mean knowledge score was 10.203.91. More than 76% of the participants knew that CVD is preventable. Ninety-one percent liked exercising and believed that exercising would make them feel better. The average mean scores for attitudes of participants toward CVD were 30.31 ± 3.21 out of 36. The authors conclude that there is a need for enhancing mothers' general knowledge about the disease, because of the increasing rates of CVD in females. This will lead to improvements in attitude and practice. Furthermore, learning in groups of 12 can be a beneficial educational method.
Measuring Spatial Dependence for Infectious Disease Epidemiology

Global spatial clustering is the tendency of points, here cases of infectious disease, to occur closer together than expected by chance. The extent of global clustering can provide a window into the spatial scale of disease transmission, thereby providing insights into the mechanism of spread, and informing optimal surveillance and control. Here the authors present an interpretable measure of spatial clustering, τ, which can be understood as a measure of relative risk. When biological or temporal information can be used to identify sets of potentially linked and likely unlinked cases, this measure can be estimated without knowledge of the underlying population distribution. The greater our ability to distinguish closely related (i.e., separated by few generations of transmission) from more distantly related cases, the more closely τ will track the true scale of transmission. The authors illustrate this approach using examples from the analyses of HIV, dengue and measles, and provide an R package implementing the methods described. The statistic presented, and measures of global clustering in general, can be powerful tools for analysis of spatially resolved data on infectious diseases. PMID:27196422

To assess disease-related knowledge among patients with inflammatory bowel disease and to identify the factors that are possibly associated with the knowledge level. Disease-related knowledge can positively influence the acceptance of the disease, increase treatment compliance and improve the quality of life in patients with inflammatory bowel disease. An observational, cross-sectional study was conducted and prospectively included patients from the inflammatory bowel disease programme between October 2014-July 2015. A Spanish-translated version of the 24-item Crohn's and Colitis Knowledge score was used to assess disease-related knowledge. Patients also completed a demographic and clinical questionnaire. A total of 203 patients were included, 62% were female, and 66% were diagnosed with ulcerative colitis; the median age was 34 years (range 18-79), and the median disease duration was four years. The median disease-related knowledge score was 9 (range 1-20). Only 29% of the patients answered more than 50% of the questions correctly. Lower disease-related knowledge was observed in questions related to pregnancy/fertility and surgery/complications. Patients older than 50 years, with ulcerative colitis, with disease durations less than five years and patients without histories of surgery exhibited lower disease-related knowledge. There was no association between the knowledge scores and the educational levels. The patients who attended our inflammatory bowel disease programme exhibited poor disease-related knowledge that was similar to the knowledge levels that have been observed in developed countries. It is necessary to assess patient knowledge to develop educational strategies and evaluate the influences of these strategies on patient compliance and quality of life. These results will allow the inflammatory bowel disease team to develop educational programmes that account for the disease-related knowledge of each patient. Inflammatory bowel disease nurses should evaluate their interventions to provide evidence that educating our patients contributes to improving their treatment outcomes and overall health statuses. © 2016 John Wiley & Sons Ltd.
A tale of two health literacies: public health and clinical approaches to health literacy.
Pleasant, Andrew; Kuruvilla, Shyama
2008-06-01
Public health concerns underlie a considerable portion of the global burden of disease, increasing the utility and need for promoting and assessing the knowledge about public health issues. Health literacy is generally agreed upon as a means to find, understand, analyze and use information to make better decisions about health and to ultimately reduce inequities in health. A public health literacy knowledge scale was tested in China, Mexico, Ghana and India. A somewhat unexpected finding, which was that experts 'scored' less on the scale than the general public, led to consideration of differences between clinical and public health approaches to health literacy and their implications. These differences in perspective, for instance consideration of single case effects versus impacts at the societal level, pose significant challenges to developing and assessing health literacy. We suggest that a comprehensive approach to health literacy will include both clinical and public health approaches.

We examined the knowledge regarding heavy drinking and smoking as risk factors of stroke according to drinking/smoking habits among randomly selected Japanese general population. The Japan Stroke Association and co-researchers have performed a large-scale educational intervention to improve knowledge concerning stroke from 2006 to 2008. Prior to above-mentioned intervention, we conducted mail-surveillance on knowledge about stroke in 11,306 randomly selected residents aged 40 to 74. We assessed the relationship between drinking/smoking habits and knowledge regarding heavy drinking and smoking as risk factors by using the chi-square test and multiple logistic regression analysis adjusting for age, sex, area, employment, living situation, history of stroke and other stroke related diseases, history of liver disease, family history of stroke and drinking (non-drinker / ex-drinker / occasional drinker / habitual drinker) / smoking habits (non-smoker / ex-smoker / current smoker). Total 5,540 subjects (49.0%) participated in this study. Ex-smokers and current smokers had better knowledge regarding smoking as a risk factor of stroke than non-smokers (odds ratio and 95% confidence intervals: 1.89, 1.55-2.31, 1.76, 1.45-2.12, respectively). There was no difference between habitual drinkers and non-drinkers in their knowledge, whereas current smokers had greater knowledge regarding smoking than nonsmokers. Accordingly, it is suggested that it will be necessary for habitual drinkers to be enlightened regarding heavy drinking as a risk factor of stroke and for current smokers to be provided with information regarding not only these risks but also the specific strategies for invoking behavioral changes.
Aggregation of alpha-synuclein by a coarse-grained Monte Carlo simulation
NASA Astrophysics Data System (ADS)
Farmer, Barry; Pandey, Ras
Alpha-synuclein, an intrinsic protein abundant in neurons, is believed to be a major cause of neurodegenerative diseases (e.g. Alzheimer, Parkinson's disease). Abnormal aggregation of ASN leads to Lewy bodies with specific morphologies. We investigate the self-organizing structures in a crowded environment of ASN proteins by a coarse-grained Monte Carlo simulation. ASN is a chain of 140 residues. Structure detail of residues is neglected but its specificity is captured via unique knowledge-based residue-residue interactions. Large-scale simulations are performed to analyze a number local and global physical quantities (e.g. mobility profile, contact map, radius of gyration, structure factor) as a function of temperature and protein concentration. Trend in multi-scale structural variations of the protein in a crowded environment is compared with that of a free protein chain.

A spatially-explicit, stochastic model is developed for Bahia bark scaling, a threat to citrus production in north-eastern Brazil, and is used to assess epidemiological principles underlying the cost-effectiveness of disease control strategies. The model is fitted via Markov chain Monte Carlo with data augmentation to snapshots of disease spread derived from a previously-reported multi-year experiment. Goodness-of-fit tests strongly supported the fit of the model, even though the detailed etiology of the disease is unknown and was not explicitly included in the model. Key epidemiological parameters including the infection rate, incubation period and scale of dispersal are estimated from the spread data. This allows us to scale-up the experimental results to predict the effect of the level of initial inoculum on disease progression in a typically-sized citrus grove. The efficacies of two cultural control measures are assessed: altering the spacing of host plants, and roguing symptomatic trees. Reducing planting density can slow disease spread significantly if the distance between hosts is sufficiently large. However, low density groves have fewer plants per hectare. The optimum density of productive plants is therefore recovered at an intermediate host spacing. Roguing, even when detection of symptomatic plants is imperfect, can lead to very effective control. However, scouting for disease symptoms incurs a cost. We use the model to balance the cost of scouting against the number of plants lost to disease, and show how to determine a roguing schedule that optimises profit. The trade-offs underlying the two optima we identify-the optimal host spacing and the optimal roguing schedule-are applicable to many pathosystems. Our work demonstrates how a carefully parameterised mathematical model can be used to find these optima. It also illustrates how mathematical models can be used in even this most challenging of situations in which the underlying epidemiology is ill-understood.
An automated framework for hypotheses generation using literature.
Abedi, Vida; Zand, Ramin; Yeasin, Mohammed; Faisal, Fazle Elahi

In bio-medicine, exploratory studies and hypothesis generation often begin with researching existing literature to identify a set of factors and their association with diseases, phenotypes, or biological processes. Many scientists are overwhelmed by the sheer volume of literature on a disease when they plan to generate a new hypothesis or study a biological phenomenon. The situation is even worse for junior investigators who often find it difficult to formulate new hypotheses or, more importantly, corroborate if their hypothesis is consistent with existing literature. It is a daunting task to be abreast with so much being published and also remember all combinations of direct and indirect associations. Fortunately there is a growing trend of using literature mining and knowledge discovery tools in biomedical research. However, there is still a large gap between the huge amount of effort and resources invested in disease research and the little effort in harvesting the published knowledge. The proposed hypothesis generation framework (HGF) finds "crisp semantic associations" among entities of interest - that is a step towards bridging such gaps. The proposed HGF shares similar end goals like the SWAN but are more holistic in nature and was designed and implemented using scalable and efficient computational models of disease-disease interaction. The integration of mapping ontologies with latent semantic analysis is critical in capturing domain specific direct and indirect "crisp" associations, and making assertions about entities (such as disease X is associated with a set of factors Z). Pilot studies were performed using two diseases. A comparative analysis of the computed "associations" and "assertions" with curated expert knowledge was performed to validate the results. It was observed that the HGF is able to capture "crisp" direct and indirect associations, and provide knowledge discovery on demand. The proposed framework is fast, efficient, and robust in generating new hypotheses to identify factors associated with a disease. A full integrated Web service application is being developed for wide dissemination of the HGF. A large-scale study by the domain experts and associated researchers is underway to validate the associations and assertions computed by the HGF.

This study was conducted to determine the level of osteoporosis knowledge and beliefs among nursing college students in Damascus. A worrying deficit of knowledge was found. They believed osteoporosis to be a serious disease but did not feel susceptible to or concerned about it. Innovative educational interventions should be considered. Increasing awareness, knowledge, and promoting healthy behaviors about osteoporosis and related risk factors are effective prevention measures for building and maintaining strong bone throughout the life-span. We hypothesized a lack of knowledge and unhealthy beliefs about osteoporosis among young women in our setting. The level of osteoporosis knowledge, beliefs, and behavior among nursing college students in Damascus was evaluated in this study. A cross-sectional study was conducted on a convenience sample of female young students seen at the nursing school. All students registered for the year 2011-2012 were included in the study. A self-administered questionnaire was implemented. The questionnaire included background information and both osteoporosis-related tools (Arabic version), namely the Osteoporosis Knowledge Assessment Tool (OKAT) and the Osteoporosis Health Belief Scale. A total of 353 female students answered the questionnaire with a response rate of 98.3%. A worrying deficit of knowledge was found among surveyed Syrian young adult females with a total mean score of 7.9 (2.7) out of possible 20 points, being 39.6% of possible maximum score on the OKAT. Those young women believed osteoporosis to be a serious disease but did not feel susceptible to or concerned about the illness. Perceived moderate to high barriers to exercises and calcium intake indicated negative health beliefs. The findings generally reveal poor knowledge about osteoporosis among nursing school female students at Damascus. Integration of osteoporosis in school curricula and public education efforts is urgently needed.
A Knowledge-Base for a Personalized Infectious Disease Risk Prediction System.
Vinarti, Retno; Hederman, Lucy
2018-01-01
We present a knowledge-base to represent collated infectious disease risk (IDR) knowledge. The knowledge is about personal and contextual risk of contracting an infectious disease obtained from declarative sources (e.g. Atlas of Human Infectious Diseases). Automated prediction requires encoding this knowledge in a form that can produce risk probabilities (e.g. Bayesian Network - BN). The knowledge-base presented in this paper feeds an algorithm that can auto-generate the BN. The knowledge from 234 infectious diseases was compiled. From this compilation, we designed an ontology and five rule types for modelling IDR knowledge in general. The evaluation aims to assess whether the knowledge-base structure, and its application to three disease-country contexts, meets the needs of personalized IDR prediction system. From the evaluation results, the knowledge-base conforms to the system's purpose: personalization of infectious disease risk.
The diversity-disease relationship: evidence for and criticisms of the dilution effect.
Huang, Z Y X; VAN Langevelde, F; Estrada-Peña, A; Suzán, G; DE Boer, W F

The dilution effect, that high host species diversity can reduce disease risk, has attracted much attention in the context of global biodiversity decline and increasing disease emergence. Recent studies have criticized the generality of the dilution effect and argued that it only occurs under certain circumstances. Nevertheless, evidence for the existence of a dilution effect was reported in about 80% of the studies that addressed the diversity-disease relationship, and a recent meta-analysis found that the dilution effect is widespread. We here review supporting and critical studies, point out the causes underlying the current disputes. The dilution is expected to be strong when the competent host species tend to remain when species diversity declines, characterized as a negative relationship between species' reservoir competence and local extinction risk. We here conclude that most studies support a negative competence-extinction relationship. We then synthesize the current knowledge on how the diversity-disease relationship can be modified by particular species in community, by the scales of analyses, and by the disease risk measures. We also highlight the complex role of habitat fragmentation in the diversity-disease relationship from epidemiological, evolutionary and ecological perspectives, and construct a synthetic framework integrating these three perspectives. We suggest that future studies should test the diversity-disease relationship across different scales and consider the multiple effects of landscape fragmentation.

The aim of this study was to assess community knowledge and behavioral impact of the social mobilization and communication strategy applied in a dengue high-risk area in Sri Lanka. A group of adults visiting selected primary care facilities in Colombo district were interviewed to collect socio-demographic data, attributes of knowledge regarding dengue and the responsive behaviors adopted by them following the dengue control program though the media and social marketing campaigns. These attributes were classified as 'good', 'fair,' or 'poor' by developing a composite scale for analysis and interpretation of data. The primary source of information was television in the majority. The overall knowledge of the disease, vector and control methods was poor. The overall level of contribution to dengue control activities was good. Awareness of the disease and its complications had not contributed to favorable behavior changes. While the social mobilization and behavior change campaign in Sri Lanka had low impact on knowledge and behaviors, a better understating of community perceptions of DF and how these perceptions are formulated within the social and cultural context; would be useful to improve uptake. This knowledge would be valuable for program planners to strengthen dengue control activities in SL and other similar settings across the region.

Aim: This study was conducted to assess the extent of knowledge, awareness, attitude, and risks of zoonotic diseases among livestock owners in Puducherry region. Materials and Methods: A total of 250 livestock farmers were selected randomly from eight revenue villages. And each farmer was interviewed with a questionnaire containing both open- and close-ended questions on various aspects of zoonotic diseases, a total of 49 questionnaires were framed to assess the source and transmission of infection to the farmers and to test their knowledge and awareness about zoonotic diseases. The data collected were analyzed by chi-square test using software Graph pad prism, and results were used to assess the relationship between education level and zoonotic disease awareness; risk of zoonotic diseases and its relation with independent variables. Results: The present survey analysis represents that most of the respondents are belonging to the age group of 41-60 years. About 42.8% of respondents’ household having a graduate. The most of the respondent are small-scale farmers and their monthly income was less than Rs. 10,000. About 61.2% of farmers were keeping their animal shed clean. About 29.6% of the respondents were ignorant about cleaning the dog bitten wound. Only 16.4% of respondents knew that diseases in animals can be transmitted to humans. Only 4.8%, 3.6%, 6.8%, and 22.4% of respondents knew about the zoonotic potential of diseases such as brucellosis, tuberculosis (TB), anthrax, and avian flu, respectively. Only 18% of the respondents were aware about zoonotic diseases from cattle. Regarding the list of zoonotic diseases contracted, 37.7% reported respiratory infection, 31.1% digestive disturbances, 15.5% had dermatological problem, and 15.5% reported indiscrete disease such as fever, body pain, and headache joint pain. From the respondent got the zoonotic disease (n=45), 51.2% of the respondent reported chronic infection and 48.8% of the respondent reported acute form of zoonotic infection. About 30% of the respondents’ farm had an incidence of abortion. Our analyses showed that there was significant in educational level of respondents and treatment of dog bitten animals. Furthermore, there was statistical significance in occurrence of hand and foot lesions in the respondent and occurrence of foot-and-mouth disease outbreak in their animals. Conclusion: From this study, it is concluded that involvement of educated family members in farming practices can create awareness and improve knowledge toward zoonotic disease. Further creation of awareness toward zoonotic diseases is of utmost important. PMID:27733806

Neurodegenerative diseases such as Alzheimer's disease (AD) follow a slowly progressing dysfunctional trajectory, with a large presymptomatic component and many comorbidities. Using preclinical models and large-scale omics studies ranging from genetics to imaging, a large number of processes that might be involved in AD pathology at different stages and levels have been identified. The sheer number of putative hypotheses makes it almost impossible to estimate their contribution to the clinical outcome and to develop a comprehensive view on the pathological processes driving the clinical phenotype. Traditionally, bioinformatics approaches have provided correlations and associations between processes and phenotypes. Focusing on causality, a new breed of advanced and more quantitative modeling approaches that use formalized domain expertise offer new opportunities to integrate these different modalities and outline possible paths toward new therapeutic interventions. This article reviews three different computational approaches and their possible complementarities. Process algebras, implemented using declarative programming languages such as Maude, facilitate simulation and analysis of complicated biological processes on a comprehensive but coarse-grained level. A model-driven Integration of Data and Knowledge, based on the OpenBEL platform and using reverse causative reasoning and network jump analysis, can generate mechanistic knowledge and a new, mechanism-based taxonomy of disease. Finally, Quantitative Systems Pharmacology is based on formalized implementation of domain expertise in a more fine-grained, mechanism-driven, quantitative, and predictive humanized computer model. We propose a strategy to combine the strengths of these individual approaches for developing powerful modeling methodologies that can provide actionable knowledge for rational development of preventive and therapeutic interventions. Development of these computational approaches is likely to be required for further progress in understanding and treating AD. Copyright © 2017 the Alzheimer's Association. Published by Elsevier Inc.

The aim was to investigate beliefs about oral health care tasks among nursing staff caring for home-dwelling older people using the Nursing Dental Coping Beliefs (nursing DCBS) index. The study population comprised nursing staff working at the homes and sheltered accommodations of older people in Ylivieska, Finland (N = 141). The data were collected using the nursing DCBS index (five-point Likert scale). On average, the nurses held moderate to high Oral health care beliefs, Internal locus of control beliefs and External locus of control beliefs, but low beliefs about Self-efficacy. The nurses with an earlier adjunct education scored lower for Oral health care beliefs on the factor Knowledge about preventing gum diseases (OR = 0.3, 95% CI: 0.1-0.9) than did the others. Regarding beliefs about External locus of control, the age group 31-49 years scored lower on the factor Retaining teeth as one ages (OR = 0.2, 95% CI: 0.1-0.7), but scored higher on the factor How to prevent dental diseases (OR = 5.6, 95% CI: 1.1-29.3) than did younger nurses (≤30 years). The nurses with only a nursing education showed significantly higher mean scores on the Self-efficacy factor Confidence of the need for dental knowledge than did those with an earlier adjunct education (P = 0.034). The nursing staff mostly believed that oral diseases are preventable and teeth can be retained in advanced age, but failed to recognize the value of dental knowledge and had little confidence in their ability to manage oral diseases. Improving the oral health-related knowledge and self-efficacy beliefs of nursing staff will require additional oral health education. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The purpose of this study was to investigate the association of diabetes-related knowledge and treatment adherence with glycaemic control among patients with type 2 diabetes mellitus (T2DM) in Pakistan. The study was designed as a questionnaire-based, cross-sectional analysis. T2DM patients attending a public outpatient clinic in Sargodha, Pakistan, were targeted for the study. In addition to the demographic information, the Urdu version of Michigan Diabetes Knowledge Test and Morisky Medication Adherence Scale was used for data collection. Patients' medical records were reviewed for glycated haemoglobin levels (HbA1c). Descriptive statistics were used to elaborate sociodemographic characteristics. The Spearman's Rho correlation was used to measure association of disease-related knowledge and treatment adherence with glycaemic control. SPSS V 20.0 was used for data analysis and p<0.05 was taken as significant. In total, 392 T2DM patients were included in the study. The mean age (SD) of these patients was 50.77±9.671 years, 56.6% were males and 90% (n=353) of respondents were married. The mean (SD) duration of disease was 5.58 (4.09) years with median HbA1c of 9.00 (IQR=8.20-10.40). The median knowledge score was 8.0 (IQR=6.0-10.0), while the median adherence score was 4.7 (IQR=3.0-6.0). HbA1c had non-significant and weak negative association with diabetes-related knowledge (r=-0.036, p=0.404) and treatment adherence (r=-0.071, p=0.238). There was negative association reported between HbA1c, treatment adherence and diabetes-related knowledge. Greater efforts are clearly required to investigate other factors affecting glycaemic control among T2DM patients in Pakistan. Copyright © 2015 Primary Care Diabetes Europe.

There is a lack of valid health care transition readiness (HCT) scales in Spanish. To provide initial validation of the UNC TRxANSITION Scale™ among Mexican adolescents and young adults (youth) with chronic kidney disease (CKD). We used the professionally translated/back translated, provider-administered UNC TRxANSITION Scale™ (Ferris et al., 2012). This 33-question scale measures HCT in ten sub-scales including knowledge about diagnosis or treatment, diet, reproductive health, school/work, insurance, ability to self-manage and looking for new health providers. Its maximum score is 10. We enrolled 163 Mexican adolescents (48.5% females) with CKD stage≥3, mean age of 15.1years (±2.1) and whose primary language is Spanish. There were 15 patients on hemodialysis (9.2%) and 30 transplant recipients (18.4%). Results were compared to those reported in adolescents with chronic conditions from the USA. Our cohort's overall median total score was 5.9. Patients≥16years old had a median total score of 6.4, whereas younger patients had median score of 5.6 (p<0.05). Transplant patients had greater scores in the total and the sub-scales of medication knowledge, issues of reproduction, insurance, trade/work and adherence (p<0.05). When comparing the total score (by age), results from our Mexican youth were similar to those reported in youth from the USA. In our Mexican cohort of youth with CKD, health care transition readiness is greater in older patients and in transplant recipients. Our cohort's overall score is low, indicating the need for a health care transition preparation program. The UNC TRxANSITION Scale™ results in Mexican youth with CKD are comparable to findings in youth from the USA. Copyright © 2015 Elsevier Inc. All rights reserved.
Epistasis and Its Implications for Personal Genetics
Moore, Jason H.; Williams, Scott M.
2009-01-01
The widespread availability of high-throughput genotyping technology has opened the door to the era of personal genetics, which brings to consumers the promise of using genetic variations to predict individual susceptibility to common diseases. Despite easy access to commercial personal genetics services, our knowledge of the genetic architecture of common diseases is still very limited and has not yet fulfilled the promise of accurately predicting most people at risk. This is partly because of the complexity of the mapping relationship between genotype and phenotype that is a consequence of epistasis (gene-gene interaction) and other phenomena such as gene-environment interaction and locus heterogeneity. Unfortunately, these aspects of genetic architecture have not been addressed in most of the genetic association studies that provide the knowledge base for interpreting large-scale genetic association results. We provide here an introductory review of how epistasis can affect human health and disease and how it can be detected in population-based studies. We provide some thoughts on the implications of epistasis for personal genetics and some recommendations for improving personal genetics in light of this complexity. PMID:19733727

Visual information is a crucial aspect of medical knowledge. Building a comprehensive medical image base, in the spirit of the Unified Medical Language System (UMLS), would greatly benefit patient education and self-care. However, collection and annotation of such a large-scale image base is challenging. To combine visual object detection techniques with medical ontology to automatically mine web photos and retrieve a large number of disease manifestation images with minimal manual labeling effort. As a proof of concept, we first learnt five organ detectors on three detection scales for eyes, ears, lips, hands, and feet. Given a disease, we used information from the UMLS to select affected body parts, ran the pretrained organ detectors on web images, and combined the detection outputs to retrieve disease images. Compared with a supervised image retrieval approach that requires training images for every disease, our ontology-guided approach exploits shared visual information of body parts across diseases. In retrieving 2220 web images of 32 diseases, we reduced manual labeling effort to 15.6% while improving the average precision by 3.9% from 77.7% to 81.6%. For 40.6% of the diseases, we improved the precision by 10%. The results confirm the concept that the web is a feasible source for automatic disease image retrieval for health image database construction. Our approach requires a small amount of manual effort to collect complex disease images, and to annotate them by standard medical ontology terms.

The inaugural issue of Circulation: Cardiovascular Genetics arrives at a remarkable time in the history of genetic research and cardiovascular medicine. Despite tremendous progress in knowledge gained, cardiovascular disease(CVD) remains the leading cause of death in the United States,1 and it has overcome infectious diseases as the leading cause of death worldwide.2 In addition, rates of CVD remain higher in black and Hispanic populations in the United States.1 The recent Strategic Plan of the National Heart, Lung,and Blood Institute (NHLBI) emphasizes research areas to fill the significant knowledge gaps needed to improve the diagnosis,treatment, and control of known risk factors and clinically apparent disease. Simultaneously, the NHLBI Strategic Plan recognizes a tremendous opportunity that is available for use of genetic and genomic research to generate new knowledge that might reduce the morbidity and mortality from CVD in US populations.3 Public availability of vast amounts of detailed sequence information about the human genome, completed sequence data on dozens of other animal genomes, and private sector development of high-throughput genetic technologies has transformed in a few short years the conduct of cardiovascular genetics and genomics research from a primary focus on mendelian disorders to a current emphasis on genome-wide association studies (GWAS; Figure1). In this review, we describe the rationale for the current emphasis on large-scale genomic studies, summarize the evolving approaches and progress to date, and identify immediate-term research needs. The National Institutes of Health (NIH) and the NHLBI are supporting a portfolio of large-scale genetic and genomic programs in diverse US populations with the longer-term objective of translating knowledge into the prediction, prevention, and preemption of CVD, as well as lung, sleep, and blood disorders. Underlying this portfolio is a strong commitment to make available participant-level data and aggregate research results to the broad community of investigators, while protecting the privacy and confidentiality and respecting the informed consent of study participants.

In the last two decades, urbanization has intensified, and in Brazil, about 90% of the population now lives in urban centers. Atmospheric patterns have changed owing to the high growth rate of cities, with negative consequences for public health. This research aims to elucidate the spatial patterns of air pollution and respiratory diseases. A data-based model to aid local urban management to improve public health policies concerning air pollution is described. An example of data preparation and multivariate analysis with inventories from different cities in the Metropolitan Region of Curitiba was studied. A predictive model with outstanding accuracy in prediction of outbreaks was developed. Preliminary results describe relevant relations among morbidity scales, air pollution levels, and atmospheric seasonal patterns. The knowledge gathered here contributes to the debate on social issues and public policies. Moreover, the results of this smaller scale study can be extended to megacities.

The capability to assess the impacts of large-scale biological attacks and the efficacy of containment policies is critical and requires knowledge-intensive reasoning about social response and disease transmission within a complex social system. There is a close linkage among social networks, transportation networks, disease spread, and early detection. Spatial dimensions related to public gathering places such as hospitals, nursing homes, and restaurants, can play a major role in epidemics [Klovdahl et. al. 2001]. Like natural epidemics, bioterrorist attacks unfold within spatially defined, complex social systems, and the societal and networked response can have profound effects on their outcome. This paper focuses on bioterrorist attacks, but the model has been applied to emergent and familiar diseases as well.

Volunteers and staff of women's organisations who are highly active in engaging and providing community service can be recruited to motivate female smokers to quit. We described the knowledge and attitudes regarding tobacco control and smoking cessation among these affiliates in Hong Kong and identified factors associated with the practices of cessation interventions. Eight of 14 women's organisations joining the Women Against Tobacco Taskforce agreed to participate. All staff, volunteers, and members of the eight organisations were invited to complete a self-administered anonymous questionnaire during July and August 2006. A total of 623 out of 771 (80.8%) affiliates responded. Their knowledge on smoking and health (mean = 3.91, SD = 1.44 on a range of 0-7), smoking related diseases (mean = 2.91, SD = 0.97 on a range of 0-4), and women-specific diseases (mean = 2.93, SD = 1.87 on a range of 0-6), was considered to be inadequate. They had positive attitudes towards tobacco control (mean = 3.31, SD = 0.55) and their own role in smoking cessation counselling (mean = 3.19, SD = 0.56) on a 4-point Likert scale and 39.3% reported had attempted to offer quitting advice. Logistic regression analysis found that participants having direct contact with smokers who had a positive attitude towards their own role in smoking cessation counselling (OR = 2.57; 95% CI = 1.67-3.95) and better knowledge of smoking and smoking-related diseases (OR = 1.35; 95% CI = 1.06-1.71) were more likely to provide cessation counselling after controlling for gender; knowledge on smoking and health, and women-specific diseases; attitude towards tobacco control, negative and positive attitudes towards female smokers, and perceived self-efficacy in smoking cessation counselling. Women's organisations showed limited support towards tobacco control and their affiliates had a limited knowledge on smoking and health but had positive attitudes. Appropriate training, capacity building and establishing rapport with women's organisations are needed to promote smoking cessation and to support tobacco control in the community. © 2010 Blackwell Publishing Ltd.

Social support and knowledge of the disease have been shown to facilitate adaptation to a chronic disease. However, the adaptation process is not fully understood. We hypothesized that these factors can contribute to better adaptation to the disease through their impact on disease-related cognitive appraisal. To analyze the links between social support and the knowledge of the disease, on one hand, and disease-related appraisals, on the other hand, one hundred fifty-eight women with stress UI, aged 32 to 79, took part in the study. Questionnaire measures of knowledge of UI, social support, and disease-related appraisals were used in the study. The level of knowledge correlated significantly negatively with the appraisal of the disease as Harm. The global level of social support correlated significantly positively with three disease-related appraisals: Profit, Challenge, and Value. Four subgroups of patients with different constellations of social support and knowledge of the disease were identified in cluster analysis and were demonstrated to differ significantly on four disease-related appraisals: Profit, Challenge, Harm, and Value. Different cognitive appraisals of UI may be specifically related to social support and knowledge of the disease, with social support affective positive disease-related appraisals, and the knowledge affecting the appraisal of Harm.

New Genes and New Insights from Old Genes: Update on Alzheimer Disease
Ringman, John M.; Coppola, Giovanni
2013-01-01
Purpose of Review: This article discusses the current status of knowledge regarding the genetic basis of Alzheimer disease (AD) with a focus on clinically relevant aspects. Recent Findings: The genetic architecture of AD is complex, as it includes multiple susceptibility genes and likely nongenetic factors. Rare but highly penetrant autosomal dominant mutations explain a small minority of the cases but have allowed tremendous advances in understanding disease pathogenesis. The identification of a strong genetic risk factor, APOE, reshaped the field and introduced the notion of genetic risk for AD. More recently, large-scale genome-wide association studies are adding to the picture a number of common variants with very small effect sizes. Large-scale resequencing studies are expected to identify additional risk factors, including rare susceptibility variants and structural variation. Summary: Genetic assessment is currently of limited utility in clinical practice because of the low frequency (Mendelian mutations) or small effect size (common risk factors) of the currently known susceptibility genes. However, genetic studies are identifying with confidence a number of novel risk genes, and this will further our understanding of disease biology and possibly the identification of therapeutic targets.

The modern biomedical research and healthcare delivery domains have seen an unparalleled increase in the rate of innovation and novel technologies over the past several decades. Catalyzed by paradigm-shifting public and private programs focusing upon the formation and delivery of genomic and personalized medicine, the need for high-throughput and integrative approaches to the collection, management, and analysis of heterogeneous data sets has become imperative. This need is particularly pressing in the translational bioinformatics domain, where many fundamental research questions require the integration of large scale, multi-dimensional clinical phenotype and bio-molecular data sets. Modern biomedical informatics theory and practice has demonstrated the distinct benefits associated with the use of knowledge-based systems in such contexts. A knowledge-based system can be defined as an intelligent agent that employs a computationally tractable knowledge base or repository in order to reason upon data in a targeted domain and reproduce expert performance relative to such reasoning operations. The ultimate goal of the design and use of such agents is to increase the reproducibility, scalability, and accessibility of complex reasoning tasks. Examples of the application of knowledge-based systems in biomedicine span a broad spectrum, from the execution of clinical decision support, to epidemiologic surveillance of public data sets for the purposes of detecting emerging infectious diseases, to the discovery of novel hypotheses in large-scale research data sets. In this chapter, we will review the basic theoretical frameworks that define core knowledge types and reasoning operations with particular emphasis on the applicability of such conceptual models within the biomedical domain, and then go on to introduce a number of prototypical data integration requirements and patterns relevant to the conduct of translational bioinformatics that can be addressed via the design and use of knowledge-based systems.

Given the panoply of system-level diseases that result from disordered inflammation, such as sepsis, atherosclerosis, cancer, and autoimmune disorders, understanding and characterizing the inflammatory response is a key target of biomedical research. Untangling the complex behavioral configurations associated with a process as ubiquitous as inflammation represents a prototype of the translational dilemma: the ability to translate mechanistic knowledge into effective therapeutics. A critical failure point in the current research environment is a throughput bottleneck at the level of evaluating hypotheses of mechanistic causality; these hypotheses represent the key step toward the application of knowledge for therapy development and design. Addressing the translational dilemma will require utilizing the ever-increasing power of computers and computational modeling to increase the efficiency of the scientific method in the identification and evaluation of hypotheses of mechanistic causality. More specifically, development needs to focus on facilitating the ability of non-computer trained biomedical researchers to utilize and instantiate their knowledge in dynamic computational models. This is termed "dynamic knowledge representation." Agent-based modeling is an object-oriented, discrete-event, rule-based simulation method that is well suited for biomedical dynamic knowledge representation. Agent-based modeling has been used in the study of inflammation at multiple scales. The ability of agent-based modeling to encompass multiple scales of biological process as well as spatial considerations, coupled with an intuitive modeling paradigm, suggest that this modeling framework is well suited for addressing the translational dilemma. This review describes agent-based modeling, gives examples of its applications in the study of inflammation, and introduces a proposed general expansion of the use of modeling and simulation to augment the generation and evaluation of knowledge by the biomedical research community at large.

The attitudes toward people with epilepsy are influenced by the degree of knowledge of the condition. The social problems encountered by school children with epilepsy as a result of negative attitude and beliefs are quite enormous. The study therefore looked at the knowledge, attitudes, and perceptions of teachers, who see a lot of epileptics, relate to them on a daily basis and have influence on them. A cross-sectional survey, using a self-administered questionnaire obtained from the author of a similar study in the United States, was carried out among 269 school teachers randomly selected from various secondary schools in Osogbo, the Osun State capital in South-West Nigeria. The questionnaire included the scale of attitudes toward persons with epilepsy and knowledge about epilepsy as well as demographic and teaching experience survey among others. Despite the high level of education of the teachers ranging from Masters Degree to National Certificate in Education, there were significant deficits in terms of general knowledge about epilepsy (70% of the respondents reported their general knowledge about epilepsy in the lower half of the scale). There was also poor knowledge of the first aids measures in the classrooms. Below one-third (29.2%) felt it was contagious and 40% of respondents reported that sufferers should not be kept in regular classes. However, their attitudes toward epilepsy were generally positive. We concluded that teachers need to have health education courses on common disease conditions such as epilepsy that are prevalent in school age; this might help to reduce the prejudice and increase the acceptance of epileptic individuals in the classrooms. Also, generally public health campaigns should be encouraged in this field.

Systems medicine is the application of systems biology concepts, methods, and tools to medical research and practice. It aims to integrate data and knowledge from different disciplines into biomedical models and simulations for the understanding, prevention, cure, and management of complex diseases. Complex diseases arise from the interactions among disease-influencing factors across multiple levels of biological organization from the environment to molecules. To tackle the enormous challenges posed by complex diseases, we need a modeling and simulation framework capable of capturing and integrating information originating from multiple spatiotemporal and organizational scales. Multiscale modeling and simulation in systems medicine is an emerging methodology and discipline that has already demonstrated its potential in becoming this framework. The aim of this chapter is to present some of the main concepts, requirements, and challenges of multiscale modeling and simulation in systems medicine.

Infectious disease knowledge and behaviors are key elements that ensure student health and safety. This study explores the impact of health education on student knowledge and behaviors toward infectious diseases and determines the factors affecting infectious diseases knowledge and behaviors among students in Gansu, China. A cross-sectional study and three sampling methods were used in two counties, 12 schools, and 32 classes in Gansu, China, from 2012 to 2013. Collected data included the following: (1) sociodemographic characteristics of 2002 students (1001 participants in the intervention group and 1001 in the control group); (2) accuracy of student knowledge and behaviors toward infectious diseases based on comparison of intervention and control groups through X 2 test; and (3) mean scores on knowledge and behavior of students with different characteristics toward infectious diseases, as analyzed through analysis of variance (ANOVA). Multiple linear regression was conducted to analyze factors affecting student knowledge and behaviors toward infectious diseases. Statistically significant differences were observed among eight items of infectious disease transmission and treatment knowledge between intervention and control groups ( P < 0.001). Average accuracies of knowledge and behaviors toward infectious diseases reached 72.23% and 60.03%. Significant differences were observed in six items on student behavior in rural and urban areas ( P < 0.001). Health education, household register, and county affected scores of student knowledge and behaviors toward infectious diseases ( P < 0.05). Gender and education level also affected scores of student behaviors toward infectious diseases ( P < 0.001). Health education contributes to student knowledge and behaviors toward infectious diseases. Students in the control group need intensified health education on infectious diseases. Health education needs to pay particular attention to rural students, all male students, and students at senior high school level living on campus.

Genetic carrier screening is increasingly possible for many conditions, but it is important to ensure decisions are informed. The multidimensional measure of informed choice (MMIC) is a quantitative instrument developed to evaluate informed choice in prenatal screening for Down syndrome, measuring knowledge, attitudes and uptake. To apply the MMIC in other screening settings, the knowledge scale must be modified. To develop and validate a modified MMIC knowledge scale for use with women undergoing carrier screening for fragile X syndrome (FXS). Responses to MMIC items were collected through questionnaires as part of a FXS carrier screening pilot study in a preconception setting in Melbourne, Australia. Ten knowledge scale items were developed using a modified Delphi technique. Cronbach's alpha and factor analysis were used to validate the new FXS knowledge scale. We summarized the knowledge, attitudes and informed choice status based on the modified MMIC. Two hundred and eighty-five women were recruited, 241 eligible questionnaires were complete for analysis. The FXS knowledge scale items measured one salient construct and were internally consistent (alpha = 0.70). 71% (172/241) of participants were classified as having good knowledge, 70% (169/241) had positive attitudes and 27% (65/241) made an informed choice to accept or decline screening. We present the development of a knowledge scale as part of a MMIC to evaluate informed choice in population carrier screening for FXS. This can be used as a template by other researchers to develop knowledge scales for other conditions for use in the MMIC. © 2012 John Wiley & Sons Ltd.

Current biomedical research needs to leverage and exploit the large amount of information reported in scientific publications. Automated text mining approaches, in particular those aimed at finding relationships between entities, are key for identification of actionable knowledge from free text repositories. We present the BeFree system aimed at identifying relationships between biomedical entities with a special focus on genes and their associated diseases. By exploiting morpho-syntactic information of the text, BeFree is able to identify gene-disease, drug-disease and drug-target associations with state-of-the-art performance. The application of BeFree to real-case scenarios shows its effectiveness in extracting information relevant for translational research. We show the value of the gene-disease associations extracted by BeFree through a number of analyses and integration with other data sources. BeFree succeeds in identifying genes associated to a major cause of morbidity worldwide, depression, which are not present in other public resources. Moreover, large-scale extraction and analysis of gene-disease associations, and integration with current biomedical knowledge, provided interesting insights on the kind of information that can be found in the literature, and raised challenges regarding data prioritization and curation. We found that only a small proportion of the gene-disease associations discovered by using BeFree is collected in expert-curated databases. Thus, there is a pressing need to find alternative strategies to manual curation, in order to review, prioritize and curate text-mining data and incorporate it into domain-specific databases. We present our strategy for data prioritization and discuss its implications for supporting biomedical research and applications. BeFree is a novel text mining system that performs competitively for the identification of gene-disease, drug-disease and drug-target associations. Our analyses show that mining only a small fraction of MEDLINE results in a large dataset of gene-disease associations, and only a small proportion of this dataset is actually recorded in curated resources (2%), raising several issues on data prioritization and curation. We propose that joint analysis of text mined data with data curated by experts appears as a suitable approach to both assess data quality and highlight novel and interesting information.

Schizophrenia is a debilitating disorder that often requires the affected individual to receive care from a caregiver. Willingness to Pay (WTP) technique allows a valuation of the health state preferences by assessing the impact of the disease and translating it into monetary terms. The objective was to determine the WTP of schizophrenic patients' caregivers on a hypothetical recovery scenario and correlate it to socio-demographic and clinical characteristics, Knowledge of Disease, Quality of life and Burden of Disease. A convenience sample consecutively assessed 189 outpatients' caregivers from Schizophrenia Program of Federal University of Sao Paulo. A single caregiver was considered for each patient, taking into consideration their close relationship and their direct involvement in the treatment. Open WTP questionnaire for a hypothetical schizophrenia recovery scenario, KAST (Knowledge of Disease), SF-6D (Quality of life) and ZBI-22 (Burden of Disease) scales were applied. A monthly WTP mean value (SD) of US\\USD 63.63 (111.88) was found. The average value (SD) found was 12.96 (2.45) on KAST, 0.78 (0.08) on SF6D and 29.91 (16.10) on ZARIT. Income, education, social class, knowledge of disease and burden of caregiver were positively correlated to the WTP value. By linear regression model, income and education remained significant. Willingness to Pay (WTP) is a method that can be used to determine the strength of preference of patients and caregivers for a recovery in schizophrenia. The higher the income and education, the higher the willingness to pay. No clinical characteristics of patients had a statistically significant relation to the value the caregiver would pay. WTP is a potentially useful tool to determine values and health care preferences, and can be used for the development of mental health policies. Future research should be used to enhance WTP tool in mental health studies on the impact of diseases, including schizophrenia.

In Nigeria, one of the major challenges associated with evidence-to-policy link in the control of infectious diseases of poverty (IDP), is deficient information literacy knowledge and skill among policymakers. There is need for policymakers to acquire the skill to discover relevant information, accurately evaluate retrieved information and to apply it correctly. To use information literacy tool of International Network for Availability of Scientific Publications (INASP) to enhance policymakers' knowledge and skill for policymaking on control of IDP in Nigeria. Modified "before and after" intervention study design was used in which outcomes were measured on target participants both before the intervention is implemented and after. This study was conducted in Ebonyi State, south-eastern Nigeria and participants were career health policy makers. A two-day health-policy information literacy training workshop was organized to enhance participants" information literacy capacity. Topics covered included: introduction to information literacy; defining information problem; searching for information online; evaluating information; science information; knowledge sharing interviews; and training skills. A total of 52 policymakers attended the workshop. The pre-workshop mean rating (MNR) of knowledge and capacity for information literacy ranged from 2.15-2.97, while the post-workshop MNR ranged from 3.34-3.64 on 4-point scale. The percentage increase in MNR of knowledge and capacity at the end of the workshop ranged from 22.6%-55.3%. The results of this study suggest that through information literacy training workshop policy makers can acquire the knowledge and skill to identify, capture and share the right kind of information in the right contexts to influence relevant action or a policy decision.

Although the detection rate for unruptured intracranial aneurysm (UIA) has improved since the 1990s, the quality of life and psychosocial status of patients living with UIA have been negatively affected. However, a comprehensive assessment tool for UIA patients is still awaited. This study aimed to develop and validate a disease-specific scale to assess UIA patients' psychosocial well-being in their daily lives. On the basis of previous qualitative research, 52 items on a six-dimension scale were generated. After a pilot study, statistical analysis was conducted to examine construct validity-including convergent validity, discriminant and known-group validity, and internal reliability. Between 2010 and 2011, 124 patients across three hospitals in Japan were tested using a tentative scale. As a result of exploratory factor analysis, we identified 25 items based on five conceptually derived dimensions (psychological stability, trust in healthcare resources, satisfaction with the decision-making process, positive perception of self-management, and confidence in UIA knowledge) as a final psychosocial well-being scale for UIA patients (UIA-PW scale). Cronbach's alpha coefficients for each subscale ranged between .76 and .90, with .83 for the total score, which indicated satisfactory internal consistency. The total score for the UIA-PW scale correlated significantly with the existing quality of life and mental health scales, but it is important to note that psychological stability and positive perception of self-management were negatively correlated. Although additional investigation is needed, the UIA-PW scale shows reasonable validity and reliability in assessing psychosocial well-being of patients living with UIA.

The aims of this study were to explore advanced breast cancer patients' knowledge of treatment intent and expectation of illness course and to evaluate their relationship with optimism, hope, and quality of life (QoL). Patients with advanced breast cancer (n = 55) who were treated in the ambulatory clinic of the University of Hacettepe were included in the study. They completed Life Orientation Scale, The Hope Scale, and the European Organization for Research and Treatment of Cancer Quality of Life questionnaires. The data regarding the knowledge of illness progression and the perceptions of therapy intent were assessed using self-administered open-ended questionnaires that were answered by the patients. The data revealed that 58.2 % of the patients had an inaccurate perception of treatment intent, believing the aim of treatment was cure, whereas only 38.2 % of the patients had a realistic expectation that their disease may remain stable or may progress over a year. In addition, the awareness of disease progression and perception of goals of treatment was significantly related to hope and optimism scores but not to QoL. A large proportion of patients diagnosed with advanced breast cancer believed that their treatment was "curative", and they would improve within a year. Findings of our study suggest that patients with inaccurate perception of treatment intent and unrealistic expectation of prognosis have higher hope and optimism scores than those who do not, but there were no significant differences in terms of global health status.

To assess patient satisfaction, perception of self-management, and perception of disease state knowledge with pharmacist-led diabetes and cardiovascular disease state management (DSM) programs. A self-insured chain of grocery store pharmacies in the Kansas City metropolitan area administers pharmacist-led diabetes and cardiovascular DSM programs for eligible employees and dependents. A modified version of the Diabetes Disease State Management Questionnaire was used to assess patient satisfaction with the DSM programs. Demographic information was also collected. Survey items were based on a 5-point Likert scale (1 = strongly disagree and 5 = strongly agree). Patients were eligible to complete the survey if he or she had been in at least 1 DSM program for 6 months. Data were assessed using descriptive statistics and analysis of variance. Across 20 pharmacies, 281 eligible participants were identified, and 46% (n = 128) completed a survey. Means for summed items relating to overall satisfaction (8 items), self-management (5 items), and knowledge (4 items) were 36.6/40 (standard deviation [SD] = 3.9), 20.9/25 (SD = 3.4), and 17.6/20 (SD = 2.1), respectively. Participant comments further indicated that the program and pharmacists are helpful and increase motivation and accountability. Positive patient responses to the program support use of pharmacist-led DSM programs. © The Author(s) 2015.

Successfully addressing neglected tropical diseases requires nuanced understandings of pathogenic landscapes that incorporate situated, contexualized community knowledge. In the case of Buruli ulcer (BU), the role of social science is vital to investigate complex human-environment interactions and navigate different ways of knowing. We analyze a set of qualitative data from our interdisciplinary project on BU in Ghana, drawing from participatory mapping, focus group discussions, semi-structured interviews, and open-ended survey questions to explore how people in endemic and non-endemic areas see themselves embedded in changing environmental and social landscapes. We pay particular attention to landscape disturbance through logging and small-scale alluvial gold mining. The results from our participatory research underscore the holistic nature of BU emergence in landscapes, encapsulated in partial and incomplete local descriptions, the relevance of collective learning to distill complexity, and the potential of rich qualitative data to inform quantitative landscape-disease models.

A study was undertaken to determine the efficacy of hygiene practices in 2 primary schools in Malawi. The study determined: (1) presence of Escherichia coli on the hands of 126 primary school pupils, (2) knowledge, awareness and hygiene practices amongst pupils and teachers and (3) the school environment through observation. Pupil appreciation of hygiene issues was reasonable; however, the high percentage presence of E. coli on hands (71%) and the evidence of large-scale open defaecation in school grounds revealed that apparent knowledge was not put into practice. The standard of facilities for sanitation and hygiene did not significantly impact on the level of knowledge or percentage of school children's hands harbouring faecal bacteria. Evidence from pupils and teachers indicated a poor understanding of principles of disease transmission. Latrines and hand-washing facilities constructed were not child friendly. This study identifies a multidisciplinary approach to improve sanitation and hygiene practices within schools.

Community health professionals play a significant role in dementia care. However, little is known about community health professionals' capacity in dementia care, especially in low and middle-income countries. The aim of the present study was to assess community health professionals' dementia knowledge, attitudes and care approach in China, a country with the largest population of people with dementia in the world and where community based dementia care services are much needed. A cross-sectional survey was conducted. 450 health professionals were recruited into the study using random sampling from community health service centres in Changsha, China. Their knowledge, attitudes and care approach were assessed utilising the Chinese version of the Alzheimer's Disease Knowledge Scale, Dementia Care Attitude Scale and Approach to Advanced Dementia Care Questionnaire respectively. A total of 390 participants returned the questionnaire (response rate 87%). Age, education, professional group and care experience were associated with knowledge scores, and overall dementia knowledge was poor. Attitudes were generally positive and influenced by age, professional group, gender and care experience. The experience of caring for people with dementia was positively associated with a person-centred care approach, although the participants tended not to use a person-centred care approach. A statistically significant association was found between knowledge and attitudes (r = 0.379, P < 0.001), and between attitudes and care approach (r = 0.143, P < 0.001). However, dementia knowledge has no relationship with a person-centred approach. Community health professionals showed generally positive attitudes towards people with dementia. However, they demonstrated poor dementia knowledge and tended not to use a person-centred care approach. The results suggest that a multifaceted approach consisting of educational interventions for community health professionals, and policy and resource development to meet the demand for community dementia care services, is urgently needed in China.

Most studies on this knowledge in the general population have been in high-income countries, but the tobacco use burden is increasing in low-income and middle-income countries. We sought to estimate levels of knowledge about tobacco-related diseases in 22 countries and determine the factors associated with differences in knowledge. We used data from the Global Adult Tobacco Survey (GATS), a nationally representative survey of persons aged ≥15 years. GATSs were conducted from 2008 to 2013 in 22 low-income and middle-income countries. Information was gathered on tobacco-related knowledge and noticing of antismoking mass media messages and health warning labels on cigarette packages. We constructed a four-point knowledge scale and performed multivariate regression analyses. Median country values for the proportion of adults who believed smoking causes a specific illness were 95.9% for lung cancer, 82.5% for heart attack and 74.0% for stroke. Knowledge scores ranged from 2.1 to 3.8. In multivariate regressions, adults scored significantly higher on the knowledge scale if they noticed antismoking media messages (22 countries) or health warning labels (17 countries). Significantly higher knowledge scores occurred in all 9 countries with pictorial health warning labels compared with only 8 out of 13 countries with text-only warning labels. Antismoking media messages appear effective for warning the public about the harms from tobacco use in all 22 countries, while warning labels are effective in the majority of these countries. Our findings suggest opportunities to motivate smoking cessation globally. Published by the BMJ Publishing Group Limited.

Asthma is a public health problem in the world, so updating the guidelines for the diagnosis and treatment of asthma is based primarily on the practice of primary care physicians. Educational interventions are useful for increasing knowledge. To compare the level of knowledge of asthma before and after an educational intervention. A quasi-experimental prospective study was conducted in general and family practitioners and pediatricians who attended a training workshop on general aspects of asthma and current guidelines for diagnosis and treatment (GINA 2014). A questionnaire consisting of 11 multiple choice questions relating to fundamental aspects of the disease and diagnosis, classification, treatment and management of attacks, was used in two assessments, baseline and post-intervention. A total of 178 patients participated in the study, with knowledge pre-intervention at 25.5 points and post-intervention at 97.5 points on a scale of 100, with p < 0.05. Educational interventions are inexpensive and effective tools to increase the knowledge of health professionals, and they have an impact on improving patient care.

Next-generation sequencing is widely used to identify disease-causing variants in patients with rare genetic disorders. Identifying those variants from whole-genome or exome data can be both scientifically challenging and time consuming. A significant amount of time is spent on variant annotation, and interpretation. Fully or partly automated solutions are therefore needed to streamline and scale this process. We describe Phenotype Driven Ranking (PDR), an algorithm integrated into Ingenuity Variant Analysis, that uses observed patient phenotypes to prioritize diseases and genes in order to expedite causal-variant discovery. Our method is based on a network of phenotype-disease-gene relationships derived from the QIAGEN Knowledge Base, which allows for efficient computational association of phenotypes to implicated diseases, and also enables scoring and ranking. We have demonstrated the utility and performance of PDR by applying it to a number of clinical rare-disease cases, where the true causal gene was known beforehand. It is also shown that PDR compares favorably to a representative alternative tool.

To investigate the periodontal examination profiles and treatment approaches of a group of Turkish general dentists. 457 general dentists were called and 173 dentists agreed to participate in the study. The questionnaire comprised 10 questions including gender, years of experience, periodontal probing during examination, oral hygiene motivation methods (do you perform, yes/no; the oral hygiene motivation method; verbal expression or using visual materials), periodontal treatments (supragingival scaling, subgingival scaling and planing or surgery) and knowledge about diagnosis and treatment for aggressive and chronic periodontitis. The participants were grouped according to their years of clinical experience: group 1: 0 to 10 years of clinical practice (n = 58); group 2: 10 to 20 years (n = 68); group 3: >20 years (n = 47). The 'periodontal probing' performance percentages were 70.69%, 26.47% and 40.43% in groups 1, 2 and 3, respectively. The oral hygiene motivation rate was high in the first 10 years of clinical practice (60.3%). In addition, 72.4% of the dentists in group 1 used visual materials in addition to verbal expression during oral hygiene motivation. 72.25% of the general dentists performed supragingival scaling. The knowledge of diagnosis and treatment of chronic periodontitis was present in >90% of the dentists surveyed. In contrast, >50% of the general dentists were not knowledgeable in the diagnosis and treatment of aggressive periodontitis. Periodontal probing is a gold standard for periodontal diagnosis, but as the dentists' clinical experience increases, the frequency of its performance decreases. The percentage of the knowledge and treatment of chronic periodontitis is higher than that of aggressive periodontitis. Postgraduate education in periodontology is important to keep general dentists up to date on current periodontal practice and improve awareness of periodontal diseases.
Low-Income US Women Under-informed of the Specific Health Benefits of Consuming Beans.
Winham, Donna M; Armstrong Florian, Traci L; Thompson, Sharon V

Bean consumption can reduce chronic disease risk and improve nutrition status. Consumer knowledge of bean health benefits could lead to increased intakes. Low-income women have poorer health and nutrition, but their level of knowledge about bean health benefits is unknown. Beans are a familiar food of reasonable cost in most settings and are cultural staples for Hispanics and other ethnicities. Study objectives were to assess awareness of bean health benefits among low-income women, and to evaluate any differences by acculturation status for Hispanic women in the Southwestern United States. A convenience sample of 406 primarily Mexican-origin (70%) low-income women completed a survey on knowledge of bean health benefits and general food behaviors. Principal components analysis of responses identified two summary scale constructs representing "bean health benefits" and "food behaviors." Acculturation level was the main independent variable in chi-square or ANOVA. The survey completion rate was 86% (406/471). Most women agreed or strongly agreed that beans improved nutrition (65%) and were satiating (62%). Over 50% answered 'neutral' to statements that beans could lower LDL cholesterol (52%), control blood glucose (56%) or reduce cancer risk (56%), indicating indifference or possible lack of knowledge about bean health benefits. There were significant differences by acculturation for beliefs that beans aid weight loss and intestinal health. Scores on the bean health benefits scale, but not the food behavior scale, also differed by acculturation. Limited resource women have a favorable view of the nutrition value of beans, but the majority did not agree or disagreed with statements about bean health benefits. Greater efforts to educate low-income women about bean health benefits may increase consumption and improve nutrition.

Pearson syndrome (PS) is a sporadic and very rare syndrome classically associated with single large-scale deletions of mitochondrial DNA and characterized by refractory sideroblastic anemia during infancy. Areas covered: This review presents an analysis and interpretation of the published data that forms the basis for our understanding of PS. PubMed, Google Scholarand Thompson ISI Web of Knowledge were searched for relevant data. Expert commentary: PS is a very rare mitochodrial disease that involves different organs and systems. Clinical phenotype is extremely variable and may change over the course of disease itself with the possibility both of worsenings and improvements. Outcome is invariably lethal and at the moment no cure is available. Accurate supportive treatment and follow up program in centres with experience in mitochondrial diseases and marrow failure may positively influence quality and duration of life.

Lyme disease case misclassification, a top public health concern, may be attributed to the current disconnect between clinical diagnosis and surveillance. This study examines Lyme disease distribution in West Virginia (WV) and determines clinicians' knowledge of both disease and surveillance. Lyme disease surveillance data for 2013 were obtained from the WV Bureau for Public Health. A validated survey, distributed to clinicians at an academic medical center, assessed clinicians' knowledge of disease diagnosis and surveillance. There were 297 adult Lyme disease cases of which 83 were confirmed. Clinician survey responses resulted in a correct response rate of 70% for Lyme disease knowledge questions. Fewer than half of all clinicians were aware of the surveillance criteria for confirming Lyme disease cases. Neither medical specialty nor previous treatment of patients with Lyme disease were significantly associated with clinicians' knowledge of the disease. Clinicians in WV are familiar with symptoms and clinical management of Lyme disease. However, they are less knowledgeable about diagnosis and public health surveillance comprising reporting and confirming cases of the disease. Clinicians and public health authorities should collaborate more closely to promote education and awareness as a key step to successfully reducing the burden of Lymne disease.

Chronic diseases are a serious and urgent problem, requiring at-scale, multi-component, multi-stakeholder action and cooperation. Despite numerous national frameworks and agenda-setting documents to coordinate prevention efforts, Australia, like many countries internationally, is yet to substantively impact the burden from chronic disease. Improved evidence on effective strategies for the prevention of chronic disease is required. This research sought to articulate a priority set of important and feasible action domains to inform future discussion and debate regarding priority areas for chronic disease prevention policy and strategy. Using concept mapping, a mixed-methods approach to making use of the best available tacit knowledge of recognised, diverse and well-experienced actors, and national actions to improve the prevention of chronic disease in Australia were identified and then mapped. Participants (ranging from 58 to 78 in the various stages of the research) included a national sample of academics, policymakers and practitioners. Data collection involved the generation and sorting of statements by participants. A series of visual representations of the data were then developed. A total of 95 statements were distilled into 12 clusters for action, namely Inter-Sectoral Partnerships; Systems Perspective/Action; Governance; Roles and Responsibilities; Evidence, Feedback and Learning; Funding and Incentive; Creating Demand; Primary Prevention; Social Determinants and Equity; Healthy Environments; Food and Nutrition; and Regulation and Policy. Specific areas for more immediate national action included refocusing the health system to prevention over cure, raising the profile of public health with health decision-makers, funding policy- and practice-relevant research, improving communication about prevention, learning from both global best-practice and domestic successes and failures, increasing the focus on primary prevention, and developing a long-term prevention strategy with an explicit funding commitment. Preventing chronic diseases and their risk factors will require at-scale, multi-component, multi-stakeholder action and cooperation. The concept mapping procedures used in this research have enabled the synthesis of views across different stakeholders, bringing both divergent and convergent perspectives to light, and collectively creating signals for where to prioritise national action. Previous national strategies for chronic disease prevention have not collated the tacit knowledge of diverse actors in the prevention of chronic disease in this structured way.

Motivation: Underrepresentation of racial groups represents an important challenge and major gap in phenomics research. Most of the current human phenomics research is based primarily on European populations; hence it is an important challenge to expand it to consider other population groups. One approach is to utilize data from EMR databases that contain patient data from diverse demographics and ancestries. The implications of this racial underrepresentation of data can be profound regarding effects on the healthcare delivery and actionability. To the best of our knowledge, our work is the first attempt to perform comparative, population-scale analyses of disease networks across three different populations, namely Caucasian (EA), African American (AA) and Hispanic/Latino (HL). Results: We compared susceptibility profiles and temporal connectivity patterns for 1988 diseases and 37 282 disease pairs represented in a clinical population of 1 025 573 patients. Accordingly, we revealed appreciable differences in disease susceptibility, temporal patterns, network structure and underlying disease connections between EA, AA and HL populations. We found 2158 significantly comorbid diseases for the EA cohort, 3265 for AA and 672 for HL. We further outlined key disease pair associations unique to each population as well as categorical enrichments of these pairs. Finally, we identified 51 key ‘hub’ diseases that are the focal points in the race-centric networks and of particular clinical importance. Incorporating race-specific disease comorbidity patterns will produce a more accurate and complete picture of the disease landscape overall and could support more precise understanding of disease relationships and patient management towards improved clinical outcomes.

The Nigerian health sector battles with control of infectious diseases and emerging non-communicable diseases. Number of healthcare personnel involved in public health programs need to be boosted to contain the health challenges of the country. Therefore, it is important to assess whether community pharmacists in Nigeria could be engaged in the promotion and delivery of various public health interventions. This study aimed to assess level of knowledge, attitude and practice of public health by community pharmacists. The cross sectional survey was carried out in Enugu metropolis. Questionnaire items were developed from expert literature. Percentage satisfactory knowledge and practice were obtained by determining the percentage of community pharmacists that were able to list more than 2 activities or that stated the correct answer. Attitude score represents the average score on the 5 point Likert scale for each item. Chi square and Fisher's exact test were used to test for statistically significant difference in knowledge, attitude and practice of public health between different groups of community pharmacists. Forty pharmacists participated in the survey. About one third of the participants had satisfactory knowledge of public health. With the exception of one item in attitude assessment, average item score ranged from 'agreed' to 'strongly agreed'. Study participants scored below satisfactory on practice of public health. Knowledge, attitude and practice of public health were not influenced by years of practice, qualification and prior public health experience. Reported barriers to the practice of public health include inadequate funds, lack of time, lack of space, cooperation of clients, inadequate staff, government regulation, insufficient knowledge, and remuneration. Level of knowledge and practice of public health by community pharmacists were not satisfactory although they had a positive attitude towards practice of public health. The findings highlight the importance of educational interventions targeted towards practicing community pharmacists to improve their knowledge level on public health issues. Providing incentives for public health services rendered could increase community pharmacists' engagement in public health activities.

To determine pharmacy students' knowledge of and attitudes toward medical marijuana and to determine if pharmacy students need additional education on the topic. Pharmacy students were asked to complete a survey on medical marijuana that assessed their knowledge of, medical uses of, adverse effects with, and attitudes toward medical marijuana through 23 Likert-scale questions. Three hundred eleven students completed the survey. Fifty-eight percent of the students felt that medical marijuana should be legalized in all states. However, the majority of students did not feel comfortable answering consumers' questions regarding efficacy, safety, or drug interactions related to the substance. Accurate responses for diseases or conditions for permitted medical marijuana use was low, with only cancer (91%) and glaucoma (57%) identified by more than half the students. With an increasing number of states adopting medical marijuana use, pharmacy schools need to evaluate the adequacy of medical marijuana education in their curriculum.

Objectives Infectious disease knowledge and behaviors are key elements that ensure student health and safety. This study explores the impact of health education on student knowledge and behaviors toward infectious diseases and determines the factors affecting infectious diseases knowledge and behaviors among students in Gansu, China. Methods A cross-sectional study and three sampling methods were used in two counties, 12 schools, and 32 classes in Gansu, China, from 2012 to 2013. Collected data included the following: (1) sociodemographic characteristics of 2002 students (1001 participants in the intervention group and 1001 in the control group); (2) accuracy of student knowledge and behaviors toward infectious diseases based on comparison of intervention and control groups through X2 test; and (3) mean scores on knowledge and behavior of students with different characteristics toward infectious diseases, as analyzed through analysis of variance (ANOVA). Multiple linear regression was conducted to analyze factors affecting student knowledge and behaviors toward infectious diseases. Results Statistically significant differences were observed among eight items of infectious disease transmission and treatment knowledge between intervention and control groups (P < 0.001). Average accuracies of knowledge and behaviors toward infectious diseases reached 72.23% and 60.03%. Significant differences were observed in six items on student behavior in rural and urban areas (P < 0.001). Health education, household register, and county affected scores of student knowledge and behaviors toward infectious diseases (P < 0.05). Gender and education level also affected scores of student behaviors toward infectious diseases (P < 0.001). Conclusions Health education contributes to student knowledge and behaviors toward infectious diseases. Students in the control group need intensified health education on infectious diseases. Health education needs to pay particular attention to rural students, all male students, and students at senior high school level living on campus. PMID:29707573
Tacit knowledge: A refinement and empirical test of the Academic Tacit Knowledge Scale.
Insch, Gary S; McIntyre, Nancy; Dawley, David
2008-11-01
Researchers have linked tacit knowledge to improved organizational performance, but research on how to measure tacit knowledge is scarce. In the present study, the authors proposed and empirically tested a model of tacit knowledge and an accompanying measurement scale of academic tacit knowledge. They present 6 hypotheses that support the proposed tacit knowledge model regarding the role of cognitive (self-motivation, self-organization); technical (individual task, institutional task); and social (task-related, general) skills. The authors tested these hypotheses with 542 responses to the Academic Tacit Knowledge Scale, which included the respondents' grade point average-the performance variable. All 6 hypotheses were supported.

To summarize excellent current research in the field of Knowledge Representation and Management (KRM) within the health and medical care domain. We provide a synopsis of the 2016 IMIA selected articles as well as a related synthetic overview of the current and future field activities. A first step of the selection was performed through MEDLINE querying with a list of MeSH descriptors completed by a list of terms adapted to the KRM section. The second step of the selection was completed by the two section editors who separately evaluated the set of 1,432 articles. The third step of the selection consisted of a collective work that merged the evaluation results to retain 15 articles for peer-review. The selection and evaluation process of this Yearbook's section on Knowledge Representation and Management has yielded four excellent and interesting articles regarding semantic interoperability for health care by gathering heterogeneous sources (knowledge and data) and auditing ontologies. In the first article, the authors present a solution based on standards and Semantic Web technologies to access distributed and heterogeneous datasets in the domain of breast cancer clinical trials. The second article describes a knowledge-based recommendation system that relies on ontologies and Semantic Web rules in the context of chronic diseases dietary. The third article is related to concept-recognition and text-mining to derive common human diseases model and a phenotypic network of common diseases. In the fourth article, the authors highlight the need for auditing the SNOMED CT. They propose to use a crowdbased method for ontology engineering. The current research activities further illustrate the continuous convergence of Knowledge Representation and Medical Informatics, with a focus this year on dedicated tools and methods to advance clinical care by proposing solutions to cope with the problem of semantic interoperability. Indeed, there is a need for powerful tools able to manage and interpret complex, large-scale and distributed datasets and knowledge bases, but also a need for user-friendly tools developed for the clinicians in their daily practice.
Postnatal Cardiac Autonomic Nervous Control in Pediatric Congenital Heart Disease
Nederend, Ineke; Jongbloed, Monique R. M.; de Geus, Eco J. C.; Blom, Nico A.; ten Harkel, Arend D. J.

Congenital heart disease is the most common congenital defect. During childhood, survival is generally good but, in adulthood, late complications are not uncommon. Abnormal autonomic control in children with congenital heart disease may contribute considerably to the pathophysiology of these long term sequelae. This narrative review of 34 studies aims to summarize current knowledge on function of the autonomic nervous system in children with a congenital heart defect. Large scale studies that measure both branches of the nervous system for prolonged periods of time in well-defined patient cohorts in various phases of childhood and adolescence are currently lacking. Pending such studies, there is not yet a good grasp on the extent and direction of sympathetic and parasympathetic autonomic function in pediatric congenital heart disease. Longitudinal studies in homogenous patient groups linking autonomic nervous system function and clinical outcome are warranted. PMID:29367565
Scale-free network provides an optimal pattern for knowledge transfer
NASA Astrophysics Data System (ADS)
Lin, Min; Li, Nan
2010-02-01
We study numerically the knowledge innovation and diffusion process on four representative network models, such as regular networks, small-world networks, random networks and scale-free networks. The average knowledge stock level as a function of time is measured and the corresponding growth diffusion time, τ is defined and computed. On the four types of networks, the growth diffusion times all depend linearly on the network size N as τ∼N, while the slope for scale-free network is minimal indicating the fastest growth and diffusion of knowledge. The calculated variance and spatial distribution of knowledge stock illustrate that optimal knowledge transfer performance is obtained on scale-free networks. We also investigate the transient pattern of knowledge diffusion on the four networks, and a qualitative explanation of this finding is proposed.

The ecological conditions of Yucatan made it a suitable region for the acquisition of vector-borne diseases such as dengue, rickettsiosis, and Chagas disease. As the epidemiological burden of these diseases shows an alarming increase of severe cases, the early establishment of diagnosis and therapeutics by first-contact physicians is a critical step that is not being fulfilled due to several reasons, including poor knowledge. To determine the level of knowledge related to dengue, Chagas disease, and rickettsiosis among rural first-contact physicians of Yucatan. A survey was applied to 90 first-contact physicians from rural clinics of Yucatan, which included 32 items related to the diagnosis, treatment, and prevention of dengue, rickettsiosis, and Chagas disease. Answers were analyzed by central tendency statistics. Differences were observed among every category, however; diagnosis and therapeutics showed the lower values. Globally, 62.5% of respondents showed moderate knowledge, 37.5% poor knowledge, and 0% adequate knowledge. Results suggest that a strong campaign for a continuous diffusion of knowledge regarding these diseases is needed. In regions with high prevalence of these kinds of diseases, like Yucatan, the impact of these results on the epidemiological burden of these diseases must be evaluated.

Dermatophytosis (ringworm) is a superficial fungal skin disease of cats that, depending on the geographic region and practice caseload, may be encountered uncommonly through to commonly. This is a self-curing disease in an immunocompetent cat. Dermatophytosis is prevalent worldwide and is one of a number of zoonotic skin diseases that cat owners are at risk of contracting. Dermatophytosis causes non-specific signs of hair loss, erythema and scaling, making it a differential diagnosis for many skin diseases of cats. The fact that this disease is infectious and contagious, and does not have any one classic clinical presentation, makes knowledge of diagnostic tools important in detection. The veterinarian's role is in early disease recognition and institution of appropriate therapy to hasten resolution of the disease. The focus of this article is to provide an update and review of the most pertinent aspects that may be helpful in the management of dermatophytosis in any single or multiple cat situation. Where appropriate, evidence from the literature is used to supplement a summary of the author's clinical experience and research in feline dermatophytosis.

Accumulating clinical researches have shown that specific microbes with abnormal levels are closely associated with the development of various human diseases. Knowledge of microbe-disease associations can provide valuable insights for complex disease mechanism understanding as well as the prevention, diagnosis and treatment of various diseases. However, little effort has been made to predict microbial candidates for human complex diseases on a large scale. In this work, we developed a new computational model for predicting microbe-disease associations by combining two single recommendation methods. Based on the assumption that functionally similar microbes tend to get involved in the mechanism of similar disease, we adopted neighbor-based collaborative filtering and a graph-based scoring method to compute association possibility of microbe-disease pairs. The promising prediction performance could be attributed to the use of hybrid approach based on two single recommendation methods as well as the introduction of Gaussian kernel-based similarity and symptom-based disease similarity. To evaluate the performance of the proposed model, we implemented leave-one-out and fivefold cross validations on the HMDAD database, which is recently built as the first database collecting experimentally-confirmed microbe-disease associations. As a result, NGRHMDA achieved reliable results with AUCs of 0.9023 ± 0.0031 and 0.9111 in the validation frameworks of fivefold CV and LOOCV. In addition, 78.2% microbe samples and 66.7% disease samples are found to be consistent with the basic assumption of our work that microbes tend to get involved in the similar disease clusters, and vice versa. Compared with other methods, the prediction results yielded by NGRHMDA demonstrate its effective prediction performance for microbe-disease associations. It is anticipated that NGRHMDA can be used as a useful tool to search the most potential microbial candidates for various diseases, and therefore boosts the medical knowledge and drug development.

This study was conducted to develop a scale to measure knowledge about hypertension among Turkish adults. The Hypertension Knowledge-Level Scale (HK-LS) was generated based on content, face, and construct validity, internal consistency, test re-test reliability, and discriminative validity procedures. The final scale had 22 items with six sub-dimensions. The scale was applied to 457 individuals aged ≥ 18 years, and 414 of them were re-evaluated for test-retest reliability. The six sub-dimensions encompassed 60.3% of the total variance. Cronbach alpha coefficients were 0.82 for the entire scale and 0.92, 0.59, 0.67, 0.77, 0.72, and 0.76 for the sub-dimensions of definition, medical treatment, drug compliance, lifestyle, diet, and complications, respectively. The scale ensured internal consistency in reliability and construct validity, as well as stability over time. Significant relationships were found between knowledge score and age, gender, educational level, and history of hypertension of the participants. No correlation was found between knowledge score and working at an income-generating job. The present scale, developed to measure the knowledge level of hypertension among Turkish adults, was found to be valid and reliable.

The west Africa Ebola virus disease (EVD) epidemic was extraordinary in scale. Now that the epidemic has ended, it is a relevant time to examine published studies with direct relevance to clinical care and, more broadly, to examine the implications of the clinical research response mounted. Clinically relevant research includes literature detailing risk factors for and clinical manifestations of EVD, laboratory and other investigation findings in patients, experimental vaccine and therapeutic clinical trials, and analyses of survivor syndrome. In this Review, we discuss new insights from patient-oriented research completed during the west Africa epidemic, identify ongoing knowledge gaps, and suggest priorities for future research.

2018-06-01
Extranodal natural killer (NK)/T-cell lymphoma (ENKTL) is an aggressive disease with poor prognosis. The lung is a relatively rare site of involvement. The current study presents a case of primary pulmonary ENKTL with fever and dyspnea, mimicking pneumonia and initially treated with empirical antibiotics. The patient demonstrated rapid deterioration and died shortly following diagnosis. To the best of our knowledge, large-scale investigations referring to primary pulmonary ENKTL are not available. As a result, the exact incidence and clinical features of primary pulmonary ENKTL are unknown. In the current report, a literature review is presented to discuss the clinical characteristics, diagnosis, treatment, and prognosis factors of this malignant disease.

The present study examines the relation between knowledge of emotion regulation strategies and social behavior in preschoolers. Knowledge of emotion regulation strategies of 210 children (mean age 55 months) was assessed. Teachers rated children's social behavior with SDQ. Linear regression analysis examined how knowledge of emotion regulation strategies influenced social behavior of children. Significant effects of gender on SDQ scales "prosocial behavior", "hyperactivity", "behavior problems", and SDQ total problem scale were identified. Age was a significant predictor of SDQ scales "prosocial behavior", "hyperactivity", "problems with peers" and SDQ total problem scale. Knowledge of emotion regulation strategies predicted SDQ total problem scores. Results suggest that deficits in knowledge of emotion regulation strategies are linked with increased problem behavior.

The Kuder-Richarson reliability for sex knowledge scale was.73, and Cronbach's agr; for sex attitude scale was.93. The findings of the study were as followed: (1) Sex knowledge was high among study samples. The average scores for sex knowledge regarding " masturbation ", " sexual harassment and sexual abuse " were among the highest; those regarding " secondary sexual characteristics ", " ovulation ", " menstruation health care ", and " sexually transmitted diseases " were among the lowest. (2) Sex attitude was positive. Eighty percent of the study subjects agreed that school nurses were responsible for the promotion of sexual health in schools. More than 90% of the study subjects were willing to participate actively in sexuality education program in school, providing health consultation and guidance. (3) Twenty percent of the study subjects were not involved in sex education because they were not invited or due to busy working schedule.(4) Marital status, highest level of education, job title, job seniority, continuing education or training experience were the factors associated with the implementation of sexuality education among school nurses.

High disease burden and scarcity of healthcare resources present complex ethical dilemmas for nurses working in developing countries. We assessed nurses' knowledge in ethics and their perceptions about Continuous Nurses' Ethics Education (CNEE) for in-service nurses. Using an anonymous, pre-tested self-administered questionnaire, we assessed nurses' knowledge in basic ethics concepts at three regional hospitals in Uganda. Adequate knowledge was measured by a score ≥50% in the knowledge assessment test. Nurses' perceptions on CNEE were assessed using a six-point Likert scale. Of 114 nurses, 91% were female; with mean age 44.7 (SD 10) years. Half were diploma, 47 (41%) certificates, 6 (5%) bachelors' degrees and one masters' level training. Overall, 18 (16%) scored ≥50% in the ethics knowledge test. Nurses with diploma or higher level of nursing training were less likely to fail the ethics knowledge than certificate-level nurses (OR 0.14, 95% CI: 0.02-0.7). Only 45% had ever attended at least one CNEE session and up to 93% agreed that CNEE is required to improve nurses' ethics knowledge and practice. Nurses exhibited low knowledge in ethics and positive attitudes towards CNEE. We recommend structured CNEE programs to address basic concepts in nursing ethics and their application in clinical practice.

Pearson syndrome (PS) is a multisystem disease including refractory anemia, vacuolization of marrow precursors and pancreatic fibrosis. The disease starts during infancy and affects various tissues and organs, and most affected children die before the age of 3years. Pearson syndrome is caused by de novo large-scale deletions or, more rarely, duplications in the mitochondrial genome. In the present report, we described a Pearson syndrome patient harboring multiple mitochondrial deletions which is, in our knowledge, the first case described and studied in Tunisia. In fact, we reported the common 4.977kb deletion and two novel heteroplasmic deletions (5.030 and 5.234kb) of the mtDNA. These deletions affect several protein-coding and tRNAs genes and could strongly lead to defects in mitochondrial polypeptides synthesis, and impair oxidative phosphorylation and energy metabolism in the respiratory chain in the studied patient.

To determine the effectiveness of a pictorial 'mind map' together with the Arthritis Research Campaign (ARC) booklet for imparting knowledge to participants with rheumatoid arthritis (RA). Also, we wished to relate this to their reading ability. We studied 363 participants with RA. Reading ability was assessed using the REALM, and knowledge was assessed using the Knowledge Scale Questionnaire (KSQ). Information on educational attainment, disease state and levels of anxiety and depression was also collected. Participants were randomly assigned to receive either the ARC booklet alone or the booklet and the mind map together. A significant minority (15%) of participants were functionally illiterate. There was a statistically significant increase in knowledge across both groups from baseline to reassessment after they were given the literature, but there was no difference in attainment between the groups. The more literate participants gained more knowledge regardless of the information they were given. They were also significantly less anxious and less depressed. The ARC booklet with or without the mind map was associated with a significant increase in knowledge. Poor readers had poor educational attainment and poor knowledge acquisition. The information on the mind map was not more accessible to them. Different educational strategies will be necessary to educate these patients.
The emerging science of precision medicine and pharmacogenomics for Parkinson's disease.
Payami, Haydeh
2017-08-01
Current therapies for Parkinson's disease are problematic because they are symptomatic and have adverse effects. New drugs have failed in clinical trials because of inadequate efficacy. At the core of the problem is trying to make one drug work for all Parkinson's disease patients, when we know this premise is wrong because (1) Parkinson's disease is not a single disease, and (2) no two individuals have the same biological makeup. Precision medicine is the goal to strive for, but we are only at the beginning stages of building the infrastructure for one of the most complex projects in the history of science, and it will be a long time before Parkinson's disease reaps the benefits. Pharmacogenomics, a cornerstone of precision medicine, has already proven successful for many conditions and could also propel drug discovery and improve treatment for Parkinson's disease. To make progress in the pharmacogenomics of Parkinson's disease, we need to change course from small inconclusive candidate gene studies to large-scale rigorously planned genome-wide studies that capture the nuclear genome and the microbiome. Pharmacogenomic studies must use homogenous subtypes of Parkinson's disease or apply the brute force of statistical power to overcome heterogeneity, which will require large sample sizes achievable only via internet-based methods and electronic databases. Large-scale pharmacogenomic studies, together with biomarker discovery efforts, will yield the knowledge necessary to design clinical trials with precision to alleviate confounding by disease heterogeneity and interindividual variability in drug response, two of the major impediments to successful drug discovery and effective treatment. © 2017 International Parkinson and Movement Disorder Society. © 2017 International Parkinson and Movement Disorder Society.

Examine outcomes for the National Parkinson Foundation (NPF) Allied Team Training for Parkinson (ATTP), an interprofessional education (IPE) program in Parkinson's disease (PD) and team-based care for medicine, nursing, occupational, physical and music therapies, physician assistant, social work and speech-language pathology disciplines. Healthcare professionals need education in evidence-based PD practices and working effectively in teams. Few evidence-based models of IPE in PD exist. Knowledge about PD, team-based care, the role of other disciplines and attitudes towards healthcare teams were measured before and after a protocol-driven training program. Knowledge, attitudes and practice changes were again measured at 6-month post-training. Trainee results were compared to results of controls. Twenty-six NPF-ATTP trainings were held across the U.S. (2003-2013). Compared to control participants (n = 100), trainees (n = 1468) showed statistically significant posttest improvement in all major outcomes, including self-perceived (p < 0.001) and objective knowledge (p < 0.001), Understanding Role of Other Disciplines (p < 0.001), Attitudes Toward Health Care Teams Scale (p < 0.001), and the Attitudes Toward Value of Teams (p < 0.001) subscale. Despite some decline, significant improvements were largely sustained at six-month post-training. Qualitative analyses confirmed post-training practice changes. The NPF-ATTP model IPE program showed sustained positive gains in knowledge of PD, team strategies and role of other disciplines, team attitudes, and important practice improvements. Further research should examine longer-term outcomes, objectively measure practice changes and mediators, and determine impact on patient outcomes. Copyright © 2015 Elsevier Ltd. All rights reserved.

Repurposing FDA-approved drugs with the aid of gene signatures of disease can accelerate the development of new therapeutics. A major challenge to developing reliable drug predictions is heterogeneity. Different gene signatures of the same disease or drug treatment often show poor overlap across studies, as a consequence of both biological and technical variability, and this can affect the quality and reproducibility of computational drug predictions. Existing algorithms for signature-based drug repurposing use only individual signatures as input. But for many diseases, there are dozens of signatures in the public domain. Methods that exploit all available transcriptional knowledge on a disease should produce improved drug predictions. Here, we adapt an established meta-analysis framework to address the problem of drug repurposing using an ensemble of disease signatures. Our computational pipeline takes as input a collection of disease signatures, and outputs a list of drugs predicted to consistently reverse pathological gene changes. We apply our method to conduct the largest and most systematic repurposing study on lung cancer transcriptomes, using 21 signatures. We show that scaling up transcriptional knowledge significantly increases the reproducibility of top drug hits, from 44% to 78%. We extensively characterize drug hits in silico, demonstrating that they slow growth significantly in nine lung cancer cell lines from the NCI-60 collection, and identify CALM1 and PLA2G4A as promising drug targets for lung cancer. Our meta-analysis pipeline is general, and applicable to any disease context; it can be applied to improve the results of signature-based drug repurposing by leveraging the large number of disease signatures in the public domain.

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

Practical relevance: Dermatophytosis (ringworm) is a superficial fungal skin disease of cats that, depending on the geographic region and practice caseload, may be encountered uncommonly through to commonly. This is a self-curing disease in an immunocompetent cat. Global importance: Dermatophytosis is prevalent worldwide and is one of a number of zoonotic skin diseases that cat owners are at risk of contracting. Clinical challenges: Dermatophytosis causes non-specific signs of hair loss, erythema and scaling, making it a differential diagnosis for many skin diseases of cats. The fact that this disease is infectious and contagious, and does not have any one classic clinical presentation, makes knowledge of diagnostic tools important in detection. The veterinarian’s role is in early disease recognition and institution of appropriate therapy to hasten resolution of the disease. Aim: The focus of this article is to provide an update and review of the most pertinent aspects that may be helpful in the management of dermatophytosis in any single or multiple cat situation. Evidence base: Where appropriate, evidence from the literature is used to supplement a summary of the author’s clinical experience and research in feline dermatophytosis. PMID:24794038

Magnetic resonance imaging (MRI) along with complex network is currently one of the most widely adopted techniques for detection of structural changes in neurological diseases, such as Parkinson's Disease (PD). In this paper, we present a digital image processing study, within the multi-layer network framework, combining more classifiers to evaluate the informative power of the MRI features, for the discrimination of normal controls (NC) and PD subjects. We define a network for each MRI scan; the nodes are the sub-volumes (patches) the images are divided into and the links are defined using the Pearson's pairwise correlation between patches. We obtain a multi-layer network whose important network features, obtained with different feature selection methods, are used to feed a supervised multi-level random forest classifier which exploits this base of knowledge for accurate classification. Method evaluation has been carried out using T1 MRI scans of 354 individuals, including 177 PD subjects and 177 NC from the Parkinson's Progression Markers Initiative (PPMI) database. The experimental results demonstrate that the features obtained from multiplex networks are able to accurately describe PD patterns. Besides, also if a privileged scale for studying PD disease exists, exploring the informative content of more scales leads to a significant improvement of the performances in the discrimination between disease and healthy subjects. In particular, this method gives a comprehensive overview of brain regions statistically affected by the disease, an additional value to the presented study.

Leptospirosis is a cosmopolitan zoonosis caused by bacteria of the genus Leptospira. Whether the distribution is worldwide, the hot and humid climate of the tropics is particularly conducive to its expansion. In most French overseas departments and territories, leptospirosis is considered as a public health problem. In French Guiana, a French department located in the northeastern part of the Amazon rainforest, it is supposed to be rare. The objective of this review was to make an inventory of the knowledge on human and animal leptospirosis in French Guiana and neighboring countries. A comprehensive search was conducted through the indexed and informal medical literature in English, French, Spanish and Portuguese. Thus, respectively ten and four publications were identified on human and animal leptospirosis in French Guiana, published between 1940 and 1995 in the form of case reports or case series. The publications concerning this disease in the other countries of the Guiana Shield, eastern Venezuela, Guyana, Suriname, and Brazilian state of Amapá, also scarce or nonexistent. However recent data from the French National Centre of leptospirosis showed a recent and sudden increase in the number of cases in the department, probably partly due to the development of diagnostic tools such as Elisa IgM serology. It is likely that leptospirosis is a neglected disease in the region, due to the lack of diagnostic tools readily available, the lack of knowledge of the local clinicians on this disease and the existence of many other pathogens with similar clinical presentation such as malaria, arboviruses and Q fever and Amazonian toxoplasmosis. The establishment of more large-scale studies on animal and human leptospirosis is necessary and urgent to know the true burden of this disease in our region.

Cystic echinococcosis (CE) is a global parasitic zoonosis caused by Echinococcus granulosus. The disease is highly endemic in western China, especially in Tibetan areas, because of poor economic development and hygiene conditions, limited community knowledge of CE, a large scale of dogs, and home slaughtering of livestock. Although many researchers have analyzed risk factors of CE transmission in Tibetan Plateau, there are rare reports of knowledge, attitude, and practice (KAP) of residents about CE in Tibetan communities. In our current study, community based cross-sectional study was conducted in three townships in Xiahe County, Gannan Tibetan Autonomous Prefectures of Gansu Province from May to September 2013. A total of 972 participants originating from Tibetan communities of 31 villages in the 3 townships were registered and data were collected using structured questionnaires. From the total of 972 study participants (457 males and 515 females), 65.9% heard of the disease CE. Most of them (96.1%) would like to accept CE inspection. About half of the peoples feed their dogs often and major of them do not play with the dogs. Risk factors included resident, knowing dog could be infected, knowing eating could be route of infection, oldest dog's age, usually feed your dog by self, feed dogs with internal organs. In general our findings showed that most of residents had positive attitude toward treatments of the disease, but their practice about disease prevention and control was low. Therefore, our study called for continued and strengthened education of changing the life style, especially the behaviors related to dogs. Copyright © 2015 The Authors. Published by Elsevier B.V.

Quality of life in psoriasis patients.
Augustin, Matthias; Radtke, Marc Alexander
2014-08-01
Patient-reported outcomes are major components of decision making in clinical research, reimbursement, health policy and health care for psoriasis. The most important construct in patient-reported outcomes is health-related quality of life (HRQoL) which encompasses the individual's well-being with respect to health. HRQoL cannot directly be measured but is assessed in single dimensions, especially physical, emotional, social and functional aspects. For this, disease- and condition-specific instruments are used. Psoriasis is a chronic inflammatory disease affecting the skin as well as other tissues and organ systems. Patients suffer from a large scale of impairments, for example, physical symptoms, stigmatization and embarrassment, psychological strain and disabilities in profession. Improvement of HRQoL is a major objective of disease management. Current knowledge on determinants of HRQoL and the treatments available increase QoL in clinical care.
The Ebb and Flow of Airborne Pathogens: Monitoring and Use in Disease Management Decisions.
Mahaffee, Walter F; Stoll, Rob
2016-05-01
Perhaps the earliest form of monitoring the regional spread of plant disease was a group of growers gathering together at the market and discussing what they see in their crops. This type of reporting continues to this day through regional extension blogs, by crop consultants and more formal scouting of sentential plots in the IPM PIPE network (http://www.ipmpipe.org/). As our knowledge of plant disease epidemiology has increased, we have also increased our ability to detect and monitor the presence of pathogens and use this information to make management decisions in commercial production systems. The advent of phylogenetics, next-generation sequencing, and nucleic acid amplification technologies has allowed for development of sensitive and accurate assays for pathogen inoculum detection and quantification. The application of these tools is beginning to change how we manage diseases with airborne inoculum by allowing for the detection of pathogen movement instead of assuming it and by targeting management strategies to the early phases of the epidemic development when there is the greatest opportunity to reduce the rate of disease development. While there are numerous advantages to using data on inoculum presence to aid management decisions, there are limitations in what the data represent that are often unrecognized. In addition, our understanding of where and how to effectively monitor airborne inoculum is limited. There is a strong need to improve our knowledge of the mechanisms that influence inoculum dispersion across scales as particles move from leaf to leaf, and everything in between.
[Cormorbidity in multiple sclerosis and its therapeutic approach].
Estruch, Bonaventura Casanova
2014-12-01
Multiple sclerosis (MS) is a long-term chronic disease, in which intercurrent processes develop three times more frequently in affected individuals than in persons without MS. Knowledge of the comorbidity of MS, its definition and measurement (Charlson index) improves patient management. Acting on comorbid conditions delays the progression of disability, which is intimately linked to the number of concurrent processes and with health states and habits. Moreover, the presence of comorbidities delays the diagnosis of MS, which in turn delays the start of treatment. The main comorbidity found in MS includes other autoimmune diseases (thyroiditis, systemic lupus erythematosus, or pemphigus) but can also include general diseases, such as asthma or osteomuscular alterations, and, in particular, psychiatric disturbances. All these alterations should be evaluated with multidimensional scales (Disability Expectancy Table, DET), which allow more accurate determination of the patient's real clinical course and quality of life. These scales also allow identification of how MS, concurrent and intercurrent processes occurring during the clinical course, and the treatment provided affect patients with MS. An overall approach to patients' health status helps to improve quality of life. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal interstitial pneumonia. The disease pathophysiology is poorly understood and the etiology remains unclear. Recent advances have generated new therapies and improved knowledge of the natural history of IPF. These gains have been brokered by advances in technology and improved insight into the role of various genes in mediating disease, but gene expression and protein levels do not always correlate. Thus, in this paper we apply a novel large scale high throughput aptamer approach to identify more than 1100 proteins in the peripheral blood of well-characterized IPF patients and normal volunteers. We use systems biology approaches to identify a unique IPF proteome signature and give insight into biological processes driving IPF. We found IPF plasma to be altered and enriched for proteins involved in defense response, wound healing and protein phosphorylation when compared to normal human plasma. Analysis also revealed a minimal protein signature that differentiated IPF patients from normal controls, which may allow for accurate diagnosis of IPF based on easily-accessible peripheral blood. This report introduces large scale unbiased protein discovery analysis to IPF and describes distinct biological processes that further inform disease biology.

The goals of this study were: (1) to evaluate patients' knowledge regarding advance directives and completion rates of advance directives among gynecologic oncology patients and (2) to examine the association between death anxiety, disease symptom burden, and patient initiation of advance directives. 110 gynecologic cancer patients were surveyed regarding their knowledge and completion of advance directives. Patients also completed the MD Anderson Symptom Inventory (MDASI) scale and Templer's Death Anxiety Scale (DAS). Descriptive statistics were utilized to examine characteristics of the sample. Fisher's exact tests and 2-sample t-tests were utilized to examine associations between key variables. Most patients were white (76.4%) and had ovarian (46.4%) or uterine cancer (34.6%). Nearly half (47.0%) had recurrent disease. The majority of patients had heard about advance directives (75%). Only 49% had completed a living will or medical power of attorney. Older patients and those with a higher level of education were more likely to have completed an advance directive (p<0.01). Higher MDASI Interference Score (higher symptom burden) was associated with patients being less likely to have a living will or medical power of attorney (p=0.003). Higher DAS score (increased death anxiety) was associated with patients being less likely to have completed a living will or medical power of attorney (p=0.03). Most patients were familiar with advance directives, but less than half had created these documents. Young age, lower level of education, disease-related interference with daily activities, and a higher level of death anxiety were associated with decreased rates of advance directive completion, indicating these may be barriers to advance care planning documentation. Young patients, less educated patients, patients with increased disease symptom burden, and patients with increased death anxiety should be targeted for advance care planning discussions as they may be less likely to engage in advance care planning.

Chronic disease management: teaching medical students to incorporate community.
Dent, M Marie; Mathis, Mary W; Outland, Monita; Thomas, McKinley; Industrious, DeShawn
2010-01-01
As a response to the growing prevalence of chronic disease, models of chronic care have emerged as salient approaches to address dynamic health care changes and to manage the burden of suffering of these diseases. Concurrently, there has been a growing call to address chronic disease management within medical school curricula. This article describes the development and evaluation of a curricular intervention designed to prepare students to integrate patient-centered care with an understanding of the patients' community, provide care within rural settings, and experience clinical education specific to chronic disease management. Second-year medical students completed a chronic disease management project as part of a 4-week community visit in rural and/or medically underserved sites. Paired pre- and post-survey data were collected using the Community Oriented Health Care Competency Scale to assess the student's knowledge, intent to practice, and attitudes toward incorporating community-oriented primary care into future practice. Matched pre- and post-project surveys were identified for 170 respondents out of 219 students (77.6% response rate). Post-assessment items were found to be statistically different from measures collected prior to the students' entrance into the community: all knowledge questions indicated significant advancements toward community responsiveness, as did one question related to attitude and three of the intent to practice community-oriented health care questions. Community-based rotations can play a positive role in developing the competencies needed for future practice. The development of curricular opportunities designed to train future physicians on the value of incorporating models of chronic care within rural and underserved communities should remain at the forefront of medical education.
Introduction to biological complexity as a missing link in drug discovery.
Gintant, Gary A; George, Christopher H
2018-06-06
Despite a burgeoning knowledge of the intricacies and mechanisms responsible for human disease, technological advances in medicinal chemistry, and more efficient assays used for drug screening, it remains difficult to discover novel and effective pharmacologic therapies. Areas covered: By reference to the primary literature and concepts emerging from academic and industrial drug screening landscapes, the authors propose that this disconnect arises from the inability to scale and integrate responses from simpler model systems to outcomes from more complex and human-based biological systems. Expert opinion: Further collaborative efforts combining target-based and phenotypic-based screening along with systems-based pharmacology and informatics will be necessary to harness the technological breakthroughs of today to derive the novel drug candidates of tomorrow. New questions must be asked of enabling technologies-while recognizing inherent limitations-in a way that moves drug development forward. Attempts to integrate mechanistic and observational information acquired across multiple scales frequently expose the gap between our knowledge and our understanding as the level of complexity increases. We hope that the thoughts and actionable items highlighted will help to inform the directed evolution of the drug discovery process.

Background The global burden of disease is increasingly dominated by non-communicable diseases.These diseases are less amenable to curative and preventative interventions than communicable disease. This presents a challenge to medical practice and medical research, both of which are experiencing diminishing returns from increasing investment. Objective Our aim was to (1) review how medical knowledge is generated, and its limitations, (2) assess the potential for emerging technologies and ideas to improve medical research, and (3) suggest solutions and recommendations to increase medical research efficiency on non-communicable diseases. Methods We undertook an unsystematic review of peer-reviewed literature and technology websites. Results Our review generated the following conclusions and recommendations. (1) Medical knowledge continues to be generated in a reductionist paradigm. This oversimplifies our models of disease, rendering them ineffective to sufficiently understand the complex nature of non-communicable diseases. (2) Some of these failings may be overcome by adopting a “Systems Medicine” paradigm, where the human body is modeled as a complex adaptive system. That is, a system with multiple components and levels interacting in complex ways, wherein disease emerges from slow changes to the system set-up. Pursuing systems medicine research will require larger datasets. (3) Increased data sharing between researchers, patients, and clinicians could provide this unmet need for data. The recent emergence of electronic health care records (EHR) could potentially facilitate this in real-time and at a global level. (4) Efforts should continue to aggregate anonymous EHR data into large interoperable data silos and release this to researchers. However, international collaboration, data linkage, and obtaining additional information from patients will remain challenging. (5) Efforts should also continue towards “Medicine 2.0”. Patients should be given access to their personal EHR data.

The global burden of disease is increasingly dominated by non-communicable diseases.These diseases are less amenable to curative and preventative interventions than communicable disease. This presents a challenge to medical practice and medical research, both of which are experiencing diminishing returns from increasing investment. Our aim was to (1) review how medical knowledge is generated, and its limitations, (2) assess the potential for emerging technologies and ideas to improve medical research, and (3) suggest solutions and recommendations to increase medical research efficiency on non-communicable diseases. We undertook an unsystematic review of peer-reviewed literature and technology websites. Our review generated the following conclusions and recommendations. (1) Medical knowledge continues to be generated in a reductionist paradigm. This oversimplifies our models of disease, rendering them ineffective to sufficiently understand the complex nature of non-communicable diseases. (2) Some of these failings may be overcome by adopting a "Systems Medicine" paradigm, where the human body is modeled as a complex adaptive system. That is, a system with multiple components and levels interacting in complex ways, wherein disease emerges from slow changes to the system set-up. Pursuing systems medicine research will require larger datasets. (3) Increased data sharing between researchers, patients, and clinicians could provide this unmet need for data. The recent emergence of electronic health care records (EHR) could potentially facilitate this in real-time and at a global level. (4) Efforts should continue to aggregate anonymous EHR data into large interoperable data silos and release this to researchers. However, international collaboration, data linkage, and obtaining additional information from patients will remain challenging. (5) Efforts should also continue towards "Medicine 2.0". Patients should be given access to their personal EHR data. Subsequently, online communities can give researchers the opportunity to ask patients for direct access to the patient's EHR data and request additional study-specific information. However, selection bias towards patients who use Web 2.0 technology may be difficult to overcome. Systems medicine, when combined with large-scale data sharing, has the potential to raise our understanding of non-communicable diseases, foster personalized medicine, and make substantial progress towards halting, curing, and preventing non-communicable diseases. Large-scale data amalgamation remains a core challenge and needs to be supported. A synthesis of "Medicine 2.0" and "Systems Science" concepts into "Systems Medicine 2.0" could take decades to materialize but holds much promise.

Data from a plethora of high-throughput sequencing studies is readily available to researchers, providing genetic variants detected in a variety of healthy and disease populations. While each individual cohort helps gain insights into polymorphic and disease-associated variants, a joint perspective can be more powerful in identifying polymorphisms, rare variants, disease-associations, genetic burden, somatic variants, and disease mechanisms. We have set up a Reference Variant Store (RVS) containing variants observed in a number of large-scale sequencing efforts, such as 1000 Genomes, ExAC, Scripps Wellderly, UK10K; various genotyping studies; and disease association databases. RVS holds extensive annotations pertaining to affected genes, functional impacts, disease associations, and population frequencies. RVS currently stores 400 million distinct variants observed in more than 80,000 human samples. RVS facilitates cross-study analysis to discover novel genetic risk factors, gene-disease associations, potential disease mechanisms, and actionable variants. Due to its large reference populations, RVS can also be employed for variant filtration and gene prioritization. A web interface to public datasets and annotations in RVS is available at https://rvs.u.hpc.mssm.edu/.

Chronic kidney disease (CKD) affects 50 million people globally. Several studies show the importance of implementing interventions that enhance patients knowledge about their disease. In 2011 the Kidney Disease Knowledge Survey (KiKS) was developed: a questionnaire that assesses the specific knowledge about chronic kidney disease in pre-dialysis patients. To translate to Spanish, culturally adapt and validate the Kidney Disease Knowledge Survey questionnaire in a population of patients with pre-dialysis chronic kidney disease. We carried out a Spanish translation and cross-cultural adaptation of the Kidney Disease Knowledge Survey questionnaire. Subsequently, we determined its validity and reliability. We determined the validity through construct validity; and reliability by evaluating its internal consistency and its intra-observer reliability (test-retest). We found a good internal consistency (Kuder-Richardson = 0.85). The intra-observer reliability was measured by the intra-class correlation coefficient that yielded a value of 0.78 (95% CI: 0.5-1.0). This value indicated a good reproducibility; also, the mean difference of -1.1 test-retest SD 6.0 (p = 0.369) confirms this finding. The translated Spanish version of the Kidney Disease Knowledge Survey is acceptable and equivalent to the original version; it also has a good reliability, validity and reproducibility. Therefore, it can be used in a population of patients with pre-dialysis chronic kidney disease.
On the potential of models for location and scale for genome-wide DNA methylation data
2014-01-01
Background With the help of epigenome-wide association studies (EWAS), increasing knowledge on the role of epigenetic mechanisms such as DNA methylation in disease processes is obtained. In addition, EWAS aid the understanding of behavioral and environmental effects on DNA methylation. In terms of statistical analysis, specific challenges arise from the characteristics of methylation data. First, methylation β-values represent proportions with skewed and heteroscedastic distributions. Thus, traditional modeling strategies assuming a normally distributed response might not be appropriate. Second, recent evidence suggests that not only mean differences but also variability in site-specific DNA methylation associates with diseases, including cancer. The purpose of this study was to compare different modeling strategies for methylation data in terms of model performance and performance of downstream hypothesis tests. Specifically, we used the generalized additive models for location, scale and shape (GAMLSS) framework to compare beta regression with Gaussian regression on raw, binary logit and arcsine square root transformed methylation data, with and without modeling a covariate effect on the scale parameter. Results Using simulated and real data from a large population-based study and an independent sample of cancer patients and healthy controls, we show that beta regression does not outperform competing strategies in terms of model performance. In addition, Gaussian models for location and scale showed an improved performance as compared to models for location only. The best performance was observed for the Gaussian model on binary logit transformed β-values, referred to as M-values. Our results further suggest that models for location and scale are specifically sensitive towards violations of the distribution assumption and towards outliers in the methylation data. Therefore, a resampling procedure is proposed as a mode of inference and shown to diminish type I error rate in practically relevant settings. We apply the proposed method in an EWAS of BMI and age and reveal strong associations of age with methylation variability that are validated in an independent sample. Conclusions Models for location and scale are promising tools for EWAS that may help to understand the influence of environmental factors and disease-related phenotypes on methylation variability and its role during disease development.

Disease-specific knowledge may influence disease outcome and quality of life in children with inflammatory bowel disease (IBD). This prospective study aimed to define IBD-related knowledge in a group of Australian children with IBD and their parents using a validated measure of disease-specific knowledge, the Inflammatory Bowel Disease Knowledge Inventory Device (IBD-KID). Children (less than 18 years) diagnosed with IBD who were members of the Australian patient support organisation were identified. Each family was sent copies of the IBD-KID. Children aged 10-18 years and all parents were asked to complete the IBD-KID and to also provide demographic details and disease characteristics. Replies were received from 196 families: 262 parents and 128 children completed questionnaires. Most children had a diagnosis of Crohn disease (65%) and 51% were male. Children diagnosed in the preceding 6 years scored higher than those with longer time since diagnosis. Parents had better scores in the IBD-KID than the children (P < 0.0001). Overall, parents and children had poor understanding of key management issues for IBD (such as side effects of steroids), important outcomes (e.g. growth) and the use of complementary therapies. Consistent patterns of IBD-related knowledge were noted in this large group of Australian children with IBD and their parents. Measurement of disease-related knowledge with the IBD-KID can identify gaps in understanding, thereby permitting focused educational activities. Although these knowledge gaps may impact upon outcomes, further prospective studies are now required to elucidate the relationships between enhanced knowledge and specific outcomes. © 2017 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

Background Uganda has reported five (5) Ebola virus disease outbreaks and three (3) Marburg virus disease outbreaks from 2000 to 2016. Peoples’ knowledge and attitude towards Ebola and Marburg virus disease impact on control and prevention measures especially during outbreaks. We describe knowledge and attitude towards Ebola and Marburg virus outbreaks in two affected communities in Uganda to inform future outbreak responses and help in the design of health education and communication messages. Methods The study was a community survey done in Luweero, Ibanda and Kamwenge districts that have experienced outbreaks of Ebola and Marburg virus diseases. Quantitative data were collected using a structured questionnaire and triangulated with qualitative participatory epidemiology techniques to gain a communities’ knowledge and attitude towards Ebola and Marburg virus disease. Results Out of 740 respondents, 48.5% (359/740) were categorized as being knowledgeable about Ebola and Marburg virus diseases, whereas 60.5% (448/740) were having a positive attitude towards control and prevention of Ebola and Marburg virus diseases. The mean knowledge and attitude percentage scores were 54.3 (SD = 23.5, 95%CI = 52.6–56.0) and 69.9 (SD = 16.9, 95%CI = 68.9–71.1) respectively. People educated beyond primary school were more likely to be knowledgeable about Ebola and Marburg virus disease than those who did not attain any formal education (OR = 3.6, 95%CI = 2.1–6.1). Qualitative data revealed that communities describe Ebola and Marburg virus diseases as very severe diseases with no cure and they believe the diseases spread so fast. Respondents reported fear and stigma suffered by survivors, their families and the broader community due to these diseases. Conclusion Communities in Uganda affected by filovirus outbreaks have moderate knowledge about these diseases and have a positive attitude towards practices to prevent and control Ebola and Marburg viral diseases. The public health sector should enhance this community knowledge gap to empower them more by supplying educational materials for epidemic preparedness in future using appropriate communication channels as proposed by the communities.

Effective translation of relevant knowledge into clinical practice is essential for modern health care systems. National Disease Management Guidelines (NDMG) are considered relevant instruments to support this transfer. To implement NDMG Internet-based continuing medical education (CME), modules and online case-based learning objects were designed and published. To ensure high quality the contents are based on NDMG and subjected to multi-step review processes. Presentation on the web was realized through a modified content management system. To obtain a CME certificate, completing an online questionnaire using a four-point Likert scale was mandatory. Between June 2003 and April 2005, 3,105 physicians were registered and used the platform: 95% of the physicians expressed positive feedback in the evaluation questionnaire, and 35% actually used the corresponding NDMG in practice. This prompted the development of interactive medical case-based learning objects as a second learning pathway. An Internet platform for CME including case-based learning objects can be a helpful tool to assure the provision of scientific knowledge for patient care.

Zika virus (ZIKV) disease has become a major public health concern. Although there are no reported cases of ZIKV disease in the United Arab Emirates (UAE), there is a potential risk of transmission due to large expatriate population and high influx of international travelers. This cross-sectional study was conducted to assess the knowledge of ZIKV disease among the students of a medical and health sciences university in the UAE. Their knowledge of ZIKV disease was assessed using a specially designed, pretested, and validated questionnaire. Of the 500 respondents included in the final analysis, 314 (62.8%) respondents presented with poor knowledge of ZIKV disease. The mean knowledge score of the study population was 10.48 ± 2.48 out of a maximum of 17. Gender, college and year of study, nationality and attendance in lecture/conference/workshop on Zika were significantly associated with the level of knowledge. The males possessed significantly ( P = 0.046) better knowledge as compared to the females. Students of medical college had significantly ( P = 0.005) better knowledge as compared to students of other colleges. The level of knowledge improved significantly ( P = 0.026) as the year of study progressed. There is a need for medical and paramedical students to update their knowledge of ZIKV disease as they are the future health-care providers who will be responsible for creating awareness about such outbreaks and their preventive measures.

[Emerging infectious diseases: complex, unpredictable processes].

In the light of a double approach, at first empirical, later theoretical and comparative, illustrated by the example of the Buruli ulcer and its mycobacterial agent Mycobacterium ulcerans on which I focused my research activity these last ten years by studying determinants and factors of emerging infectious or parasitic diseases, the complexity of events explaining emerging diseases will be presented. The cascade of events occurring at various levels of spatiotemporal scales and organization of life, which lead to the numerous observed emergences, nowadays requires better taking into account the interactions between host(s), pathogen(s) and the environment by including the behavior of both individuals and the population. In numerous research studies on emerging infectious diseases, microbial hazard is described rather than infectious disease risk, the latter resulting from the confrontation between an association of threatening phenomena, or hazards, and a susceptible population. Beyond, the theme of emerging infectious diseases and its links with global environmental and societal changes leads to reconsider some well-established knowledge in infectiology and parasitology. © Société de Biologie, 2017.

The decline in the phase prior to diagnosis of Alzheimers disease (AD) is not well known, although this knowledge is necessary to evaluate the efficiency of new drugs that can influence in disease course prior to diagnosis. To contribute to better knowledge of the decline prior to diagnosis, we have investigated the cognitive and functional deterioration for 2-3 years before the probable AD diagnosis was established. We compared results obtained by 17 control subjects and 27 patients at the time of diagnosis of a probable AD with results obtained 2-3 years before (interval of 27.7 4 months). We compared memory functions (logical, recognition, learning and autobiographical memory), naming, visual and visuospatial gnosis, visuoconstructive praxis, verbal fluency and the Mini-Mental State Examination (MMSE), Informant Questionnaire and Blessed's Scale scores. Performance of control subjects did not change. AD patients showed a significant decline in scores, except for verbal fluency. In order of importance, cognitive decline was more marked in scores of learning memory, visuospatial gnosis, autobiographical memory and visuoconstructive praxis. Decline prior to diagnosis of AD is characterized by an important learning memory impairment. Deterioration of visuospatial gnosis and visuoconstructive praxis is greater than deterioration of MMSE and Informant Questionnaire scores.

The incidence of breast cancer is rapidly increasing in Yemen with recent indications of constituting one-third of female cancers. The main problem in Yemen remains very late presentation of breast cancer, most of which should have been easily recognisable. Since stage of disease at diagnosis is the most important prognostic variable, early diagnosis is an important option to be considered for control of breast cancer in low resourced settings like Yemen. In the present study, we aimed at describing breast cancer knowledge, perceptions and breast self-examination (BSE) practices among a sample of Yemeni women. This cross-sectional study covered 400 women attending four reproductive health centres in Aden, Yemen through face-to-face interview using a structured questionnaire during April - July 2014. We collected data on sociodemographic characteristics, knowledge about breast cancer, and screening practices as well as respondents' perceptions based on the five sub scales of the Health Belief Model (HBM): perceived susceptibility; perceived severity; perceived barriers; perceived benefits; and self-efficacy. The response format was a fivepoint Likert scale. Statistical Package for Social Sciences (SPSS 20) was used for statistical analysis. Statistical significance was set at p<0.05. Logistic regression analysis was conducted with BSE as a dependent variable. The mean age of women was 26.5 (S.D=5.6) years. The majority (89.0%) had never ever performed any screening. Two-thirds of respondents had poor knowledge. Perceived BSE benefits and self-efficacy and lower BSE barriers perception were significant independent predictors of BSE practice. Poor knowledge and inadequate BSE practices are prevailing in Yemen. The need for implementing culturally sensitive targeted education measures is mandatory in the effort to improve early detection and reduce the burden of breast cancer.

Background Community health workers (CHWs) can screen for cardiovascular disease (CVD) risk as well as health professionals using a non-invasive screening tool (data unpublished). However, this demonstrated success does not guarantee effective scaling of the intervention to a population level. Objectives To report lessons learned from supervisors’ experiences monitoring CHWs and perceptions of other stakeholders regarding features for successful scaling of interventions which incorporate task-sharing with CHWs. Methods We conducted a qualitative analysis of in-depth interviews to explore stakeholder perceptions. Data was collected through interviews of 36 supervisors and administrators at non-governmental organizations contracted to deliver and manage primary care services using CHWs, directors and staff at the government health care clinics, and officials from the departments of health responsible for the implementation of health policy. Results CHWs are recognized for their value in offsetting severe human resource shortages and for their expert community knowledge. There is a lack of clear definitions for roles, expectations, and career paths for CHWs. Formal evaluation and supervisory systems are highly desirable but nonexistent or poorly implemented, creating a critical deficit for effective implementation of programs utilizing task sharing. There is acknowledgement of environmental challenges (e.g. safety) and systemic challenges (e.g. respect from trained health professionals) that hamper the effectiveness of CHWs. The government-community relationships presumed to form the basis of redesigned health care services have to be supported more explicitly and consistently on both sides in order to increase the acceptability of CHWs and their effectiveness. Conclusions The criteria critical for successful scaling of CHW led screening are consistent with evidence for scaling up communicable disease programs. Policy makers have to commit appropriate levels of resources and political will to ensure successful scaling of this intervention. PMID:25754565

Effective translational methodologies for knowledge representation are needed in order to make strides against the constellation of diseases that affect the world today. These diseases are defined by their mechanistic complexity, redundancy, and nonlinearity. Translational systems biology aims to harness the power of computational simulation to streamline drug/device design, simulate clinical trials, and eventually to predict the effects of drugs on individuals. The ability of agent-based modeling to encompass multiple scales of biological process as well as spatial considerations, coupled with an intuitive modeling paradigm, suggests that this modeling framework is well suited for translational systems biology. This review describes agent-based modeling and gives examples of its translational applications in the context of acute inflammation and wound healing. PMID:20835989

Heart failure (HF) is associated with cognitive impairment, which could negatively affect a patient's abilities to carry out self-care, potentially resulting in higher hospital readmission rates. Factors associated with self-care in patients experiencing mild cognitive impairment (MCI) are not known. This descriptive correlation study aimed to assess levels of HF self-care and knowledge and to determine the predictors of self-care in HF patients who screen positive for MCI. The Montreal Cognitive Assessment was used to screen for MCI. In 125 patients with MCI hospitalized with HF, self-care (Self-care of Heart Failure Index) and HF knowledge (Dutch Heart Failure Knowledge Scale) were assessed. We used multiple regression analysis to test a model of variables hypothesized to predict self-care maintenance, management, and confidence. Mean (SD) HF knowledge scores (11.24 [1.84]) were above the level considered to be adequate (defined as >10). Mean (SD) scores for self-care maintenance (63.57 [19.12]), management (68.35 [20.24]), and confidence (64.99 [16.06]) were consistent with inadequate self-care (defined as scores <70). In multivariate analysis, HF knowledge, race, greater disease severity, and social support explained 22% of the variance in self-care maintenance (P < .001); age, education level, and greater disease severity explained 19% of the variance in self-care management (P < .001); and younger age and higher social support explained 20% of the variance in self-care confidence scores (P < .001). Blacks, on average, scored significantly lower in self-care maintenance (P = .03). In this sample, patients who screened positive for MCI, on average, had adequate HF knowledge yet inadequate self-care scores. These models show the influence of modifiable and nonmodifiable predictors for patients who screened positive for MCI across the domains of self-care. Health professionals should consider screening for MCI and identifying interventions that address HF knowledge and social support. Further research is needed to explain the racial differences in self-care.

The February 2013 Food and Drug Administration (FDA) draft guidance for developing drugs for early-stage Alzheimer's disease (AD) creates certain challenges as they guide toward the use of one cognitive outcome to gain accelerated marketing approval for preclinical AD drugs, and a composite clinical scale - the Clinical Dementia Rating Scale in particular - for the primary outcome for prodromal AD clinical trials. In light of the developing knowledge regarding early stage diagnoses and clinical trials outcomes, we recommend that FDA describe its requirements for validating preclinical AD diagnoses for drug development purposes, maintain the principle for requiring coprimary outcomes, and encourage the advancement of outcomes for early stage AD trials. The principles for drug development for early stage AD should not differ from those for clinical AD, especially as the diagnoses of prodromal and early AD impinge on each other. The FDA should not recommend that a composite scale be used as a sole primary efficacy outcome to support a marketing claim unless it requires that the cognitive and functional components of such a scale are demonstrated to be individually meaningful. The current draft guidelines may inadvertently constrain efforts to better assess the clinical effects of new drugs and inhibit innovation in an area where evidence-based clinical research practices are still evolving.

This is the second of the two White Papers from the fourth UC Davis Cardiovascular Symposium Systems Approach to Understanding Cardiac Excitation-Contraction Coupling and Arrhythmias (3-4 March 2016), a biennial event that brings together leading experts in different fields of cardiovascular research. The theme of the 2016 symposium was 'K + channels and regulation', and the objectives of the conference were severalfold: (1) to identify current knowledge gaps; (2) to understand what may go wrong in the diseased heart and why; (3) to identify possible novel therapeutic targets; and (4) to further the development of systems biology approaches to decipher the molecular mechanisms and treatment of cardiac arrhythmias. The sessions of the Symposium focusing on the functional roles of the cardiac K + channel in health and disease, as well as K + channels as therapeutic targets, were contributed by Ye Chen-Izu, Gideon Koren, James Weiss, David Paterson, David Christini, Dobromir Dobrev, Jordi Heijman, Thomas O'Hara, Crystal Ripplinger, Zhilin Qu, Jamie Vandenberg, Colleen Clancy, Isabelle Deschenes, Leighton Izu, Tamas Banyasz, Andras Varro, Heike Wulff, Eleonora Grandi, Michael Sanguinetti, Donald Bers, Jeanne Nerbonne and Nipavan Chiamvimonvat as speakers and panel discussants. This article summarizes state-of-the-art knowledge and controversies on the functional roles of cardiac K + channels in normal and diseased heart. We endeavour to integrate current knowledge at multiple scales, from the single cell to the whole organ levels, and from both experimental and computational studies. © 2016 The Authors.

To develop the Cancer Knowledge Scale for Elders and test its validity and reliability. The number of elders suffering from cancer is increasing. To facilitate cancer prevention behaviours among elders, they shall be educated about cancer-related knowledge. Prior to designing a programme that would respond to the special needs of elders, understanding the cancer-related knowledge within this population was necessary. However, extensive review of the literature revealed a lack of appropriate instruments for measuring cancer-related knowledge. A valid and reliable cancer knowledge scale for elders is necessary. A non-experimental methodological design was used to test the psychometric properties of the Cancer Knowledge Scale for Elders. Item analysis was first performed to screen out items that had low corrected item-total correlation coefficients. Construct validity was examined with a principle component method of exploratory factor analysis. Cancer-related health behaviour was used as the criterion variable to evaluate criterion-related validity. Internal consistency reliability was assessed by the KR-20. Stability was determined by two-week test-retest reliability. The factor analysis yielded a four-factor solution accounting for 49.5% of the variance. For criterion-related validity, cancer knowledge was positively correlated with cancer-related health behaviour (r = 0.78, p < 0.001). The KR-20 coefficients of each factor were 0.85, 0.76, 0.79 and 0.67 and 0.87 for the total scale. Test-retest reliability over a two-week period was 0.83 (p < 0.001). This study provides evidence for content validity, construct validity, criterion-related validity, internal consistency and stability of the Cancer Knowledge Scale for Elders. The results show that this scale is an easy-to-use instrument for elders and has adequate validity and reliability. The scale can be used as an assessment instrument when implementing cancer education programmes for elders. It can also be used to evaluate the effects of education programmes.

Networks are commonly used to represent and analyze large and complex systems of interacting elements. In systems biology, human disease networks show interactions between disorders sharing common genetic background. We built pathway-based human phenotype network (PHPN) of over 800 physical attributes, diseases, and behavioral traits; based on about 2,300 genes and 1,200 biological pathways. Using GWAS phenotype-to-genes associations, and pathway data from Reactome, we connect human traits based on the common patterns of human biological pathways, detecting more pleiotropic effects, and expanding previous studies from a gene-centric approach to that of shared cell-processes. The resulting network has a heavily right-skewed degree distribution, placing it in the scale-free region of the network topologies spectrum. We extract the multi-scale information backbone of the PHPN based on the local densities of the network and discarding weak connection. Using a standard community detection algorithm, we construct phenotype modules of similar traits without applying expert biological knowledge. These modules can be assimilated to the disease classes. However, we are able to classify phenotypes according to shared biology, and not arbitrary disease classes. We present examples of expected clinical connections identified by PHPN as proof of principle. We unveil a previously uncharacterized connection between phenotype modules and discuss potential mechanistic connections that are obvious only in retrospect. The PHPN shows tremendous potential to become a useful tool both in the unveiling of the diseases' common biology, and in the elaboration of diagnosis and treatments.

Collective health is a paradigm with a long history in Latin America. Similarly, collective mental health has had an interesting development in certain Latin American countries, even acting to stimulate psychiatric reform. However, both paradigms appear to be encapsulated in specific times and places, among other reasons because of a hegemonic global-scale epistemology that, by imposing a naturalized model of truth, denies other forms of knowledge the opportunity to question not only already-established disease categories, treatment protocols and health policies, but the established order itself. In this article, we reflect on the power of ethnography, as both a form of knowledge and a social relation in itself, to broaden the space available for a possible field of collective health in a context where it is still incipient: Europe. The ethnographic point of view allows us to rethink that which is already accepted, creating permeability in entrenched practices and opening up surprising new possibilities.

The objective of this study was to design and develop food safety knowledge and attitude scales based on food-handling guidelines developed by a national panel of food safety experts. Knowledge (n=43) and attitude (n=49) questions were developed and pilot-tested with a variety of consumer groups. Final questions were selected based on item analysis and on validity and reliability statistical tests. Knowledge questions were tested in Washington State with participants in low-income nutrition education programs (pretest/posttest n=58, test/retest n=19) and college students (pretest/posttest n=34). Attitude questions were tested in Ohio with nutrition education program participants (n=30) and college students (non-nutrition majors n=138, nutrition majors n=57). Item analysis, paired sample t tests, Pearson's correlation coefficients, and Cronbach's alpha were used. Reliability and validity tests of individual items and the question sets were used to reduce the scales to 18 knowledge questions and 10 attitude questions. The knowledge and attitude scales covered topics ranked as important by a national panel of experts and met most validity and reliability standards. The 18-item knowledge questionnaire had instructional sensitivity (mean score increase of more than three points after instruction), internal reliability (Cronbach's alpha >.75), and produced similar results in test-retest without intervention (coefficient of stability=.81). Knowledge of correct procedures for hand washing and avoiding cross-contamination was widespread before instruction. Knowledge was limited regarding avoiding food preparation while ill, cooking hamburgers, high-risk foods, and whether cooked rice and potatoes could be stored at room temperature. The 10-item attitude scale had an appropriate range of responses (item difficulty) and produced similar results in test-retest ( P =.01). Internal consistency ranged from alpha=.63 to .89. Students anticipating a career where food safety is valued had higher attitude scale scores than participants of extension education programs. Uses for the knowledge questionnaire include assessment of subject matter knowledge before instruction and knowledge gain after instruction. The attitude scale assesses an outcome variable that may predict food safety behavior.
Transmission, Human Population, and Pathogenicity: the Ebola Case in Point.
Delgado, Rafael; Simón, Fernando
2018-03-01
The 2013-2016 Ebola outbreak in West Africa has been the largest ever of a known disease in a new context that produced an unprecedented impact and is changing the international approach to responding to public health emergencies. The unprecedented scale of the outbreak, the use of advanced technology for detecting and characterizing the infectious agent, along with the opportunity to treat patients in modern facilities have greatly increased our knowledge of the disease and its transmission. Also, for the first time, an important international effort has been deployed to control the spread of the epidemic by providing care to patients and by adopting basic measures of public health control. Apart from supportive treatment and intensive therapy with fluids and electrolytes, no new compounds have been proved to be clinically effective to treat Ebola virus disease; however, a specific vaccine has shown significant protection in clinical trials in Guinea, opening an expectation for controlling future outbreaks.

This study examined the significance of age-related subtest scores from the Japanese version of the Wechsler Adult Intelligence Scale-III in patients in the early stages of Alzheimer's disease (AD). The subjects of this study included 58 elderly Japanese persons classified into two groups: AD group (n = 29) and control group (n = 29). These groups did not differ in age, years of education, gender ratio, Hasegawa's Dementia Scale-Revised score, or Full-Scale IQ score. No subject scored below the cut-off point on Hasegawa's Dementia Scale-Revised, a frequently used dementia screen test in Japan. At the index score level, General Ability Index scores were the only scores that differed significantly between the groups, with the AD group scoring significantly lower than the control group (P < 0.05, Hedges' g = 0.54). At the subtest level, information scores were the only scores that differed significantly between the groups, with the AD group significantly lower than the control group (P < 0.01, Hedges' g = 0.74). The General Ability Index is a composite score that deducts components of working memory and processing speed, which are sensitive to decline with normal ageing, from the Full-Scale IQ. It also served as a subtest measuring crystallized intelligence, especially of acquired knowledge of general and factual information. Therefore, the results of this study seem to suggest that Wechsler Adult Intelligence Scale-III profile of very early AD may be characterized by weak performance on subtests normally resistant to decline with ageing. © 2014 The Authors.

The shape of the global causes of death
Barford, Anna; Dorling, Danny
2007-01-01
Background World maps can provide an instant visual overview of the distribution of diseases and deaths. Results There is a particular geography to each type of death: in some places many thousands of deaths are caused by a particular condition, whilst other equally populous areas have few to no deaths from the same cause. Conclusion Physicians and other health professionals often specialise in the specifics of causes, symptoms and effects. For some practitioners gaining a worldview of disease burden complements smaller scale medical knowledge of where and how people are affected by each condition. Maps can make health related information much more accessible to planners and the general public than can tables, text, or even graphs. Ten cartograms based on World Health Organisation Burden of Disease data are introduced here; alongside seven based on data from other sources. The Burden of Disease cartograms are the latest in a much larger collection of social, economic and health world maps. PMID:17956608

The authors assessed the relationship between confabulations in Alzheimer's disease and the ability to mentally travel in time to reexperience memories. Twenty-seven patients with Alzheimer's disease were administered evaluations of provoked confabulations, spontaneous confabulations, and mental time travel. Provoked and spontaneous confabulations were evaluated with questions probing personal and general knowledge and with a scale rated by nursing and medical staff. Mental time travel was assessed by asking patients to retrieve personal memories. After each memory, participants had to provide a "remember" response if they were able to retrieve the event with their encoding context or a "know" response if they knew that the event had occurred but were unable to recall any contextual details. Results showed significant negative correlations between confabulations and "remember" responses. These findings reflect a relationship between the occurrence of confabulations in patients with Alzheimer's disease and impairments in their ability to mentally project themselves in time when retrieving the context in which confabulated memories were originally encoded.

The aim of the present study was to assess the role of CX3CL1 in patients with active and inactive Behçet's Disease (BD), Neuro-Behçet's Disease (NBD) and control subjects. Fifty-six patients admitted to the BD and NBD Outpatient Clinics, and 30 healthy controls were enrolled in the study. Serum CX3CL1 levels were measured by an enzyme linked immunosorbent assay (ELISA). No significant difference was found between the serum CX3CL1 levels of control subjects, and patients with active and inactive BD or NBD, regardless of treatment. To our knowledge, this is the first study analyzing CX3CL1 levels in patients with BD and NBD. Our results demonstrated that serum CX3CL1 levels were not changed in active and inactive BD and NBD. However, further large-scale studies are needed to confirm our results. Copyright © 2011 Elsevier B.V. All rights reserved.

The multiplicity of issues, including uncertainty and ethical dilemmas, and policies involved in appraising interventions for rare diseases suggests that multicriteria decision analysis (MCDA) based on a holistic definition of value is uniquely suited for this purpose. The objective of this study was to analyze and further develop a comprehensive MCDA framework (EVIDEM) to address rare disease issues and policies, while maintaining its applicability across disease areas. Specific issues and policies for rare diseases were identified through literature review. Ethical and methodological foundations of the EVIDEM framework v3.0 were systematically analyzed from the perspective of these issues, and policies and modifications of the framework were performed accordingly to ensure their integration. Analysis showed that the framework integrates ethical dilemmas and issues inherent to appraising interventions for rare diseases but required further integration of specific aspects. Modification thus included the addition of subcriteria to further differentiate disease severity, disease-specific treatment outcomes, and economic consequences of interventions for rare diseases. Scoring scales were further developed to include negative scales for all comparative criteria. A methodology was established to incorporate context-specific population priorities and policies, such as those for rare diseases, into the quantitative part of the framework. This design allows making more explicit trade-offs between competing ethical positions of fairness (prioritization of those who are worst off), the goal of benefiting as many people as possible, the imperative to help, and wise use of knowledge and resources. It also allows addressing variability in institutional policies regarding prioritization of specific disease areas, in addition to existing uncertainty analysis available from EVIDEM. The adapted framework measures value in its widest sense, while being responsive to rare disease issues and policies. It provides an operationalizable platform to integrate values, competing ethical dilemmas, and uncertainty in appraising healthcare interventions.
Adapting Knowledge Translation Strategies for Rare Rheumatic Diseases.
Cellucci, Tania; Lee, Shirley; Webster, Fiona
2016-08-01
Rare rheumatic diseases present unique challenges to knowledge translation (KT) researchers. There is often an urgent need to transfer knowledge from research findings into clinical practice to facilitate earlier diagnosis and better outcomes. However, existing KT frameworks have not addressed the specific considerations surrounding rare diseases for which gold standard evidence is not available. Several widely adopted models provide guidance for processes and problems associated with KT. However, they do not address issues surrounding creation or synthesis of knowledge for rare diseases. Additional problems relate to lack of awareness or experience in intended knowledge users, low motivation, and potential barriers to changing practice or policy. Strategies to address the challenges of KT for rare rheumatic diseases include considering different levels of evidence available, linking knowledge creation and transfer directly, incorporating patient and physician advocacy efforts to generate awareness of conditions, and selecting strategies to address barriers to practice or policy change.

The nutritional status of patients with amyotrophic lateral sclerosis (ALS) has been shown to be associated with mortality. However, there have not been, to our knowledge, any studies on the association between nutritional status and disease severity. The present study investigated the hypothesis that nutritional status was negatively associated with disease severity using the ALS functional rating scale (ALSFRS-R). One hundred ninety-three Korean ALS patients were divided into tertiles based on their ALSFRS-R score. Dietary intake was measured using 24 h recall and nutritional status was determined by body mass index (BMI) and geriatric nutritional risk index (GNRI). BMI and GNRI were significantly lower in patients in the lowest tertile of ALSFRS-R. BMI and GNRI also correlated with ALSFRS-R score, bulbar score, albumin levels, total lymphocyte count, and total daily energy expenditure. Intakes of energy and most nutrients were significantly lower in patients in the lowest tertiles of ALSFRS-R, but significances disappeared after adjusting for energy intake. Intakes of vegetables, grains, seasonings, and oils were also significantly lower in patients in the lowest tertile of ALSFRS-R. In addition, patients in the lowest tertile of ALSFRS-R were significantly younger at disease onset, had a longer duration of ALS, less regular exercise, and less sun exposure. Nutritional status, as assessed by BMI and GNRI, was negatively associated with disease severity using ALSFRS-R. The present study suggested that intake of nutrients decreases with disease progression in ALS patients. Copyright © 2015 Elsevier Inc. All rights reserved.
Identifying Nodes of Transmission in Disease Diffusion Through Social Media
NASA Astrophysics Data System (ADS)
Lamb, David Sebastian
The spread of infectious diseases can be described in terms of three interrelated components: interaction, movement, and scale. Transmission between individuals requires some form of interaction, which is dependent on the pathogen, to occur. Diseases spread through the movement of their hosts; they spread across many spatial scales from local neighborhoods to countries, or temporal scales from days to years, or periodic intervals. Prior research into the spread of disease have examined diffusion processes retrospectively at regional or country levels, or developed differential equation or simulation models of the dynamics of disease transmission. While some of the more recent models incorporate all three components, they are limited in the way they understand where interactions occur. The focus has been on home or work, including contact with family or coworkers. The models reflect a lack of knowledge about how transmissions are made at specific locations in time, so-called nodes of transmission. That is, how individuals' intersections in time and space function in disease transmission. This project sought to use the three factors of interaction, movement, and scale to better understand the spread of disease in terms of the place of interaction called the node of transmission. The overarching objective of this research was: how can nodes of transmission be identified through individual activity spaces incorporating the three factors of infectious disease spread: interaction, movement, and scale?. This objective fed into three main sub-objectives: defining nodes of transmission, developing an appropriate methodology to identifying nodes of transmission, and applying it using geotagged social media data from Twitter. To develop an appropriate framework, this research relied on time geography, and traditional disease. This particularly relied on the idea of bundling to create the nodes, and a nesting effect that integrated scale. The data source used to identify nodes of transmission was collected from Twitter for the Los Angeles County, USA, area from October 2015 to February 2016. Automated text classification was used to identify messages where users self-reported an influenza-like-illness. Different groupings were created that combined both the syndrome and the symptoms of influenza, and applied to the automated classification. The use of Twitter for small-area health analysis was evaluated along with different text classification methodologies. A space-time hierarchical clustering technique was adapted to be applied towards the twitter data in both identifying nodes of transmission and identifying spatiotemporal contact networks. This clustering data was applied to the classified Twitter data to look at where interaction between the classified users were occurring. This pointed to six nodes that were typically densely populated areas that saw the merging of large groups of people in Los Angeles (e.g. Disneyland and Hollywood Boulevard).The movement of these individuals were also examined by using a edit distance to compare their visits to different clusters and nodes.

The management of key public health issues requires solid evidence-based knowledge for the prevention and control of various emerging or re-emerging vector borne diseases (e.g. Lyme disease, West Nile virus, etc.) and environmentally-linked diseases (e.g. enteric infections from recreational water contamination). Earth observation (EO) images enhance knowledge and capacity to characterize risk of illness across the vast Canadian territory by deriving new and up-to-date data from population, climatic and environmental determinants of health relevant to public health actions such as risk mapping, risk communication and identification of vulnerable populations.Modeling of infectious disease transmission has made possible the identification of risk areas and the underlying factors (human activities, ecology, environment and climate) that may explain this emergence. New data products derived from Earth observation satellites pertaining to climate, land cover and land use, and distribution and density of animal and human populations have greatly improved the resolution and the specificity of explanatory and predictive models.This article focuses on the scope of tele-epidemiology activities of the Canadian public health community as well as current and potential future fields of application for Earth observation data. It will demonstrate the strength, sustainability and innovative character of these approaches to improve scale-dependent decision- making at different levels of government in Canada (federal, provincial/territorial and regional) and increase the efficiency of many preventive, preparedness and response actions.Examples of tele-epidemiology applications will be presented such as the risk assessment of microbial contamination of recreational waters and modelling the risk of vector borne diseases in the Canadian context.

The completion of the Human Genome Project triggered a whole new field of genomic research which is likely to lead to new opportunities for the promotion of population health. As a result, the distinction between genetic and environmental diseases has faded. Presently, genomics and knowledge deriving from systems biology, epigenomics, integrative genomics or genome-environmental interactions give a better insight on the pathophysiology of common diseases. However, it is barely used in the prevention and management of diseases. Together with the boost in the amount of genetic association studies, this demands for appropriate public health actions. The field of Public Health Genomics analyses how genome-based knowledge and technologies can responsibly and effectively be integrated into health services and public policy for the benefit of population health. Environmental exposures interact with the genome to produce health information which may help explain inter-individual differences in health, or disease risk. However today, prospects for concrete applications remain distant. In addition, this information has not been translated into health practice yet. Therefore, evidence-based recommendations are few. The lack of population-based research hampers the evaluation of the impact of genomic applications. Public Health Genomics also evaluates the benefits and risks on a larger scale, including normative, legal, economic and social issues. These new developments are likely to affect all domains of public health and require rethinking the role of genomics in every condition of public health interest. This article aims at providing an introduction to the field of and the ideas behind Public Health Genomics. PMID:22958637

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

To understand the knowledge of acupuncture disease spectrum, expectation of acupuncture treatment in Chengdu residents. A questionnaire regarding the knowledge of acupuncture disease spectrum and expectation of acupuncture treatment in Chengdu residents was established. By field sampling and internet survey, related data were collected and analyzed. Totally 1 548 valid questionnaires were collected, including 1 041 from field survey and 507 from internet survey. The results indicated the knowledge of acupuncture and its disease spectrum were moderate in Chengdu residents; among the disease spectrum of acupuncture, the disease with the highest cognition was insomnia, accounting for 45.0% in field survey and 75.4% in internet survey; while the disease with the lowest cognition was infertility, accounting for 8.3% in field survey and 34.3% in internet survey. The knowledge of acupuncture in Chengdu residents could be further improved, and the promotion of popular science of acupuncture should be strengthened in future.
The ecology, evolution, impacts and management of host-parasite interactions of marine molluscs.
Coen, Loren D; Bishop, Melanie J
2015-10-01
Molluscs are economically and ecologically important components of aquatic ecosystems. In addition to supporting valuable aquaculture and wild-harvest industries, their populations determine the structure of benthic communities, cycling of nutrients, serve as prey resources for higher trophic levels and, in some instances, stabilize shorelines and maintain water quality. This paper reviews existing knowledge of the ecology of host-parasite interactions involving marine molluscs, with a focus on gastropods and bivalves. It considers the ecological and evolutionary impacts of molluscan parasites on their hosts and vice versa, and on the communities and ecosystems in which they are a part, as well as disease management and its ecological impacts. An increasing number of case studies show that disease can have important effects on marine molluscs, their ecological interactions and ecosystem services, at spatial scales from centimeters to thousands of kilometers and timescales ranging from hours to years. In some instances the cascading indirect effects arising from parasitic infection of molluscs extend well beyond the temporal and spatial scales at which molluscs are affected by disease. In addition to the direct effects of molluscan disease, there can be large indirect impacts on marine environments resulting from strategies, such as introduction of non-native species and selective breeding for disease resistance, put in place to manage disease. Much of our understanding of impacts of molluscan diseases on the marine environment has been derived from just a handful of intensively studied marine parasite-host systems, namely gastropod-trematode, cockle-trematode, and oyster-protistan interactions. Understanding molluscan host-parasite dynamics is of growing importance because: (1) expanding aquaculture; (2) current and future climate change; (3) movement of non-native species; and (4) coastal development are modifying molluscan disease dynamics, ultimately leading to complex relationships between diseases and cultivated and natural molluscan populations. Further, in some instances the enhancement or restoration of valued ecosystem services may be contingent on management of molluscan disease. The application of newly emerging molecular tools and remote sensing techniques to the study of molluscan disease will be important in identifying how changes at varying spatial and temporal scales with global change are modifying host-parasite systems.

Systems medicine and integrated care to combat chronic noncommunicable diseases
2011-01-01
We propose an innovative, integrated, cost-effective health system to combat major non-communicable diseases (NCDs), including cardiovascular, chronic respiratory, metabolic, rheumatologic and neurologic disorders and cancers, which together are the predominant health problem of the 21st century. This proposed holistic strategy involves comprehensive patient-centered integrated care and multi-scale, multi-modal and multi-level systems approaches to tackle NCDs as a common group of diseases. Rather than studying each disease individually, it will take into account their intertwined gene-environment, socio-economic interactions and co-morbidities that lead to individual-specific complex phenotypes. It will implement a road map for predictive, preventive, personalized and participatory (P4) medicine based on a robust and extensive knowledge management infrastructure that contains individual patient information. It will be supported by strategic partnerships involving all stakeholders, including general practitioners associated with patient-centered care. This systems medicine strategy, which will take a holistic approach to disease, is designed to allow the results to be used globally, taking into account the needs and specificities of local economies and health systems.

During the last decades, agricultural land-uses in West Africa were marked by dramatic shifts in the coverage of individual crops. Nowadays, cashew (Anacardium occidentale L.) is one of the most export-oriented horticulture crops, notably in Guinea-Bissau. Relying heavily on agriculture to increase their income, developing countries have been following a strong trend of moving on from traditional farming systems toward commercial production. Emerging infectious diseases, driven either by adaptation to local conditions or inadvertent importation of plant pathogens, are able to cause tremendous cashew production losses, with economic and social impact of which, in developing countries is often underestimated. Presently, plant genomics with metagenomics as an emergent tool, presents an enormous potential to better characterize diseases by providing extensive knowledge on plant pathogens at a large scale. In this perspective, we address metagenomics as a promising genomic tool to identify cashew fungal associated diseases as well as to discriminate the causal pathogens, aiming at obtaining tools to help design effective strategies for disease control and thus promote the sustainable production of cashew in West African Region.

Create a Spanish-language version of the Risk Perception Survey for Developing Diabetes (RPS-DD) and assess psychometric properties. The Spanish-language version was created through translation, harmonization, and presentation to the tool's original author. It was field tested in a foreignborn Latino sample and properties evaluated in principal components analysis. Personal Control, Optimistic Bias, and Worry multi-item Likert subscale responses did not cluster together. A clean solution was obtained after removing two Personal Control subscale items. Neither the Personal Disease Risk scale nor the Environmental Health Risk scale responses loaded onto single factors. Reliabilities ranged from .54 to .88. Test of knowledge performance varied by item. This study contributes to evidence of validation of a Spanish-language RPS-DD in foreign-born Latinos.

To translate and validate a Greek version of the Hypertension Knowledge-Level Scale. The major barrier in the management of hypertension is the lack of adherence to medications and lifestyle adjustments. Patients' knowledge of the nature of hypertension and cardiovascular risk factors is a significant factor affecting individuals' adherence. However, few instruments have been developed to assess patients' knowledge level and no one has been translated into Greek. This study used a case control study design. Data collection for this research occurred between February 7, 2013 and March 10, 2013. The sample included both hypertensives and non-hypertensives. Participants simultaneously completed the version of the Hypertension Knowledge-Level Scale. A total of 68 individuals completed the questionnaire. Coefficient alpha was 0·66 for hypertensives and 0·79 for non-hypertensives. The difference for the mean scores in the entire scale between the two samples was statistically significant. In addition, significant differences were observed in many sub-dimensions and no correlation was found between level, knowledge and age, gender and education level. Findings provide support for the validity of the Greek version of the Hypertension Knowledge-Level Scale. The translation and validation of an instrument evaluating the level of knowledge of hypertension contribute to assessing the provided educational intervention. Low knowledge level should lead to the development of new methods of education, therefore nurses will have the opportunity to amplify their role in patients' education and develop relationships based on honesty and respect. © 2015 John Wiley & Sons Ltd.
Integrated Bio-Entity Network: A System for Biological Knowledge Discovery
Bell, Lindsey; Chowdhary, Rajesh; Liu, Jun S.; Niu, Xufeng; Zhang, Jinfeng

A significant part of our biological knowledge is centered on relationships between biological entities (bio-entities) such as proteins, genes, small molecules, pathways, gene ontology (GO) terms and diseases. Accumulated at an increasing speed, the information on bio-entity relationships is archived in different forms at scattered places. Most of such information is buried in scientific literature as unstructured text. Organizing heterogeneous information in a structured form not only facilitates study of biological systems using integrative approaches, but also allows discovery of new knowledge in an automatic and systematic way. In this study, we performed a large scale integration of bio-entity relationship information from both databases containing manually annotated, structured information and automatic information extraction of unstructured text in scientific literature. The relationship information we integrated in this study includes protein–protein interactions, protein/gene regulations, protein–small molecule interactions, protein–GO relationships, protein–pathway relationships, and pathway–disease relationships. The relationship information is organized in a graph data structure, named integrated bio-entity network (IBN), where the vertices are the bio-entities and edges represent their relationships. Under this framework, graph theoretic algorithms can be designed to perform various knowledge discovery tasks. We designed breadth-first search with pruning (BFSP) and most probable path (MPP) algorithms to automatically generate hypotheses—the indirect relationships with high probabilities in the network. We show that IBN can be used to generate plausible hypotheses, which not only help to better understand the complex interactions in biological systems, but also provide guidance for experimental designs.

Policies for genetic testing in children (GTIC) focus on medical or psychosocial benefit to the child, discouraging or prohibiting carrier testing, and advising caution regarding pre-symptomatic diagnosis if no treatment exists. This study sought to understand parents' perspectives on these issues and determine their experiences and knowledge related to genetic testing for Batten disease - a set of inherited neurodegenerative diseases of childhood onset for which no disease modifying therapies yet exist. Parents of children with Batten disease completed a survey of their knowledge of genetics, experience with genetic testing, and opinions regarding GTIC. 54% had sought genetic testing for non-affected family members, including predictive diagnosis of healthy, at-risk children. Participation in any genetic counseling was associated with greater knowledge on questions about genetics. The majority of parents felt it was better to know ahead of time that a child would develop Batten disease, believed that this knowledge would not alter how they related to their child, and that parents should have the final say in deciding whether to obtain GTIC. Parents of children with an inherited disease are knowledgeable about genetics and wish to establish predictive or carrier status of at-risk children. Copyright © 2013 Elsevier Inc.

SparkText: Biomedical Text Mining on Big Data Framework.
Ye, Zhan; Tafti, Ahmad P; He, Karen Y; Wang, Kai; He, Max M
Many new biomedical research articles are published every day, accumulating rich information, such as genetic variants, genes, diseases, and treatments. Rapid yet accurate text mining on large-scale scientific literature can discover novel knowledge to better understand human diseases and to improve the quality of disease diagnosis, prevention, and treatment. In this study, we designed and developed an efficient text mining framework called SparkText on a Big Data infrastructure, which is composed of Apache Spark data streaming and machine learning methods, combined with a Cassandra NoSQL database. To demonstrate its performance for classifying cancer types, we extracted information (e.g., breast, prostate, and lung cancers) from tens of thousands of articles downloaded from PubMed, and then employed Naïve Bayes, Support Vector Machine (SVM), and Logistic Regression to build prediction models to mine the articles. The accuracy of predicting a cancer type by SVM using the 29,437 full-text articles was 93.81%. While competing text-mining tools took more than 11 hours, SparkText mined the dataset in approximately 6 minutes. This study demonstrates the potential for mining large-scale scientific articles on a Big Data infrastructure, with real-time update from new articles published daily. SparkText can be extended to other areas of biomedical research.

The current Ebola outbreak in West Africa has already caused substantial mortality and dire human and economic consequences. It continues to represent an alarming public health threat in the region and beyond and jeopardizes the provision of health care and other services in the affected countries. The scale of the epidemic has accelerated research efforts for diagnostics, treatment, and prevention galvanized through increased availability of funding. Our knowledge relating to the virus, disease pathogenesis, risk factors, dynamics of transmission, and epidemic control is increasing, and sociocultural factors have emerged as critical determinants for the success and failure of control efforts. However, there is a long way to go. In this review we summarize the current knowledge, examine the sociocultural context in West Africa, and outline priority areas for future research. PMID:25843598
[Notifiable infectious diseases: knowledge and notification among hospital physicians].

Notifiable infectious diseases represent a public health hazard, which is why they are under surveillance and must be reported. We tried to assess hospital physicians' knowledge of hospital physicians on notifiable infectious diseases and their self-reported attitudes to notification. An observational study was conducted using a questionnaire with 11 multiple choice questions, two yes/no questions and one short-answer question. It was distributed to all senior doctors and residents in 19 medical and surgical departments. A total of 248 questionnaires were sent out, with a response rate of 79.84%. More than three-quarters (76.3%) of the respondents were senior doctors. As regards specific knowledge about whether a particular disease is a notifiable disease, 29.5% identified correctly 100% of the named diseases, 3.2% could not identify any of them. All urgent named notifiable infectious diseases were correctly identified by 25.3% of physicians. Statistically significant differences were found in the knowledge of notifiable diseases knowledge in medical and surgical departments, as well as for senior doctors (P=.047) and residents (P=.035). A high percentage of medical services (40%) and surgical (70%) department reported never failing to notify. When asked about the causes of under-reporting, 72% did not know whether notification was mandatory or not, and 88% did not know what diseases must be notified. Although many respondents are aware that diseases notification is part of their daily activity, many of them admit under-reporting. There is insufficient knowledge about what diseases are considered notifiable infectious diseases and how to notify them. Copyright © 2012 Elsevier España, S.L. All rights reserved.

Forest systems are increasingly threatened by emergent, exotic diseases, yet management strategies for forest trees may be hindered by long generation times and scant background knowledge. We tested whether nursery disease resistance and growth traits have predictive value for the conservation of Notholithocarpus densiflorus, the host most susceptible to sudden oak death. We established three experimental populations to assess nursery growth and resistance to Phytophthora ramorum, and correlations between nursery-derived breeding values with seedling survival in a field disease trial. Estimates of nursery traits’ heritability were low to moderate, with lowest estimates for resistance traits. Within the field trial, survival likelihood was increased in larger seedlings and decreased with the development of disease symptoms. The seed-parent family wide likelihood of survival was likewise correlated with family predictors for size and resistance to disease in 2nd year laboratory assays, though not resistance in 1st year leaf assays. We identified traits and seedling families with increased survivorship in planted tanoaks, and a framework to further identify seed parents favored for restoration. The additive genetic variation and seedling disease dynamics we describe hold promise to refine current disease models and expand the understanding of evolutionary dynamics of emergent infectious diseases in highly susceptible hosts.

Asthma self-management is aimed to improve the quality and effectiveness of asthma care by supporting the patients to manage their illness by themselves. The aim of the study was to evaluate the impact of pharmacist-delivered counselling on patients knowledge and beliefs about the medicines, adherence level, and asthma control. A prospective intervention study was conducted in community pharmacies. A total of 90 patients completed the study. Four questionnaires were used: (1) Beliefs about medicines questionnaire (BMQ), (2) Knowledge of asthma and asthma medicine (KAM), (3) Asthma control test (ACT), and (4) 8-item Morisky medication adherence scale questionnaire (MMAS-8). Questionnaires were completed at baseline and 3 months later. Low level of adherence and poor asthma control were determined initially. Better asthma control was significantly associated with higher adherence level, lower concerns regarding the medication use, and knowledge of triggers. Statistically significant improvement was found after 3 months in patients knowledge of asthma and its medications, their attitude towards medications (decrease in harm, overuse and concern; increase in necessity score), asthma control score (increased from 19 to 20, p < 0.05) and level of adherence (MMAS-8 score decreased from 3 to 2 p < 0.05). Better asthma control was achieved in 60% of patients. Sixteen patients (18%) were transferred from poor to well-controlled asthma, implying no need for patients' referral to the doctor and no additional cost for the health system. Improved disease control could be a result of enhanced knowledge and understanding of the disease-medication relationship, improved inhalation technique, and support on patients' adherence. Acquired knowledge and skills, as well as improved attitude, empowered patients to take a more active part in asthma management. Education in further patients' follow-up should consider topics tailored to the patients' characteristics, needs, and prior counselling schedule with issues discussed. Copyright © 2017 Elsevier Inc.

Many people living with Chronic Obstructive Pulmonary Disease (COPD) have low general health literacy; however, there is little information available on these patients' eHealth literacy, or their ability to seek, find, understand, and appraise online health information and apply this knowledge to address or solve disease-related health concerns. A nationally representative sample of patients registered in the COPD Foundation's National Research Registry (N = 1,270) was invited to complete a web-based survey to assess socio-demographic (age, gender, marital status, education), health status (generic and lung-specific health-related quality of life), and socio-cognitive (social support, self-efficacy, COPD knowledge) predictors of eHealth literacy, measured using the 8-item eHealth literacy scale (eHEALS). Over 50% of the respondents (n = 176) were female (n = 89), with a mean age of 66.19 (SD = 9.47). Overall, participants reported moderate levels of eHealth literacy, with more than 70% feeling confident in their ability to find helpful health resources on the Internet. However, respondents were much less confident in their ability to distinguish between high- and low-quality sources of web-based health information. Very severe versus less severe COPD (β = 4.15), lower lung-specific health-related quality of life (β = -0.19), and greater COPD knowledge (β = 0.62) were significantly associated with higher eHealth literacy. Higher COPD knowledge was also significantly associated with greater knowledge (ρ = 0.24, p = .001) and use (ρ = 0.24, p = .001) of web-based health resources. Findings emphasize the importance of integrating skill-building activities into comprehensive patient education programs that enable patients with severe cases of COPD to identify high-quality sources of web-based health information. Additional research is needed to understand how new social technologies can be used to help medically underserved COPD patients benefit from web-based self-management support resources.

Objectives Rare disease research requires a broad range of disease-related information for the discovery of causes of genetic disorders that are maladies caused by abnormalities in genes or chromosomes. A rarity in cases makes it difficult for researchers to elucidate definite inception. This knowledge base will be a major resource not only for clinicians, but also for the general public, who are unable to find consistent information on rare diseases in a single location. Methods We design a compact database schema for faster querying; its structure is optimized to store heterogeneous data sources. Then, clinicians at Seoul National University Hospital (SNUH) review and revise those resources. Additionally, we integrated other sources to capture genomic resources and clinical trials in detail on the Korean Rare Disease Knowledge base (KRDK). Results As a result, we have developed a Web-based knowledge base, KRDK, suitable for study of Mendelian diseases that commonly occur among Koreans. This knowledge base is comprised of disease summary and review, causal gene list, laboratory and clinic directory, patient registry, and so on. Furthermore, database for analyzing and giving access to human biological information and the clinical trial management system are integrated on KRDK. Conclusions We expect that KRDK, the first rare disease knowledge base in Korea, may contribute to collaborative research and be a reliable reference for application to clinical trials. Additionally, this knowledge base is ready for querying of drug information so that visitors can search a list of rare diseases that is relative to specific drugs. Visitors can have access to KRDK via http://www.snubi.org/software/raredisease/. PMID:23346478

A computable knowledge base containing relations between diseases and lab tests would be a great resource for many biomedical informatics applications. This paper describes our initial step towards establishing a comprehensive knowledge base of disease and lab tests relations utilizing three public on-line resources. LabTestsOnline, MedlinePlus and Wikipedia are integrated to create a freely available, computable disease-lab test knowledgebase. Disease and lab test concepts are identified using MetaMap and relations between diseases and lab tests are determined based on source-specific rules. Experimental results demonstrate a high precision for relation extraction, with Wikipedia achieving the highest precision of 87%. Combining the three sources reached a recall of 51.40%, when compared with a subset of disease-lab test relations extracted from a reference book. Moreover, we found additional disease-lab test relations from on-line resources, indicating they are complementary to existing reference books for building a comprehensive disease and lab test relation knowledge base.

Well-developed and validated measures of cystic fibrosis (CF) knowledge are scarce. The purpose of the present study is to develop and validate a CF knowledge scale that is brief, easy to use, self-administered and demonstrates clinical utility. A comprehensive literature search generated a pool of scale items; an expert panel of CF team members reviewed and provided recommendations for item inclusion. A focus group of CF patients and family members (n = 12) then reviewed the items for face validity and reading clarity. To evaluate the validity and reliability of the newly developed CF knowledge scale, it was administered to several different samples including CF patients (n = 45), respirology patients (n = 100), health-care providers (n = 74) and university student samples (psychology students, n = 71; medical students, n = 36). Internal consistency of the scale was high, with an alpha coefficient for the overall sample of .95 (n = 326). The scale also demonstrated excellent construct validity. This study is an important first step in a line of research that aims to develop and empirically validate a psycho-educational adherence intervention for improving quality of life and treatment outcomes among adult CF patients. The CF knowledge scale has potential applications as a clinical teaching tool with patients and health-care providers and could be used as an outcome measure in CF educational intervention studies aimed at optimizing CF treatment knowledge, adherence and quality of life among CF patients. © 2014 Asian Pacific Society of Respirology.

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

In addition to traditional and novel experimental approaches to study host-pathogen interactions, mathematical and computer modelling have recently been applied to address open questions in this area. These modelling tools not only offer an additional avenue for exploring disease dynamics at multiple biological scales, but also complement and extend knowledge gained via experimental tools. In this review, we outline four examples where modelling has complemented current experimental techniques in a way that can or has already pushed our knowledge of host-pathogen dynamics forward. Two of the modelling approaches presented go hand in hand with articles in this issue exploring fluorescence resonance energy transfer and two-photon intravital microscopy. Two others explore virtual or 'in silico' deletion and depletion as well as a new method to understand and guide studies in genetic epidemiology. In each of these examples, the complementary nature of modelling and experiment is discussed. We further note that multi-scale modelling may allow us to integrate information across length (molecular, cellular, tissue, organism, population) and time (e.g. seconds to lifetimes). In sum, when combined, these compatible approaches offer new opportunities for understanding host-pathogen interactions.

The capabilities of (I) learning transferable knowledge across domains; and (II) fine-tuning the pre-learned base knowledge towards tasks with considerably smaller data scale are extremely important. Many of the existing transfer learning techniques are supervised approaches, among which deep learning has the demonstrated power of learning domain transferrable knowledge with large scale network trained on massive amounts of labeled data. However, in many biomedical tasks, both the data and the corresponding label can be very limited, where the unsupervised transfer learning capability is urgently needed. In this paper, we proposed a novel multi-scale convolutional sparse coding (MSCSC) method, that (I) automatically learns filter banks at different scales in a joint fashion with enforced scale-specificity of learned patterns; and (II) provides an unsupervised solution for learning transferable base knowledge and fine-tuning it towards target tasks. Extensive experimental evaluation of MSCSC demonstrates the effectiveness of the proposed MSCSC in both regular and transfer learning tasks in various biomedical domains. PMID:28129148

Hospital clinical staff routinely confront challenging behaviors in patients with dementia with limited training in prevention and management. The authors of the current article conducted a survey of staff on a chronic care hospital unit concerning knowledge about dementia, perceived educational needs, and the care environment. The overall mean score for a 27-item knowledge scale was 24.08 (SD = 2.61), reflecting high level of disease knowledge. However, staff indicated a need for more information and skills, specifically for managing behaviors nonpharmacologically (92.3%), enhancing patient safety (89.7%), coping with care challenges (84.2%), and involving patients in activities (81.6%). Although most staff (i.e., nurses [80%] and therapists [86.4%]) believed their care contributed a great deal to patient well-being, approximately 75% reported frustration and being overwhelmed by dementia care. Most reported being hit, bitten, or physically hurt by patients (66.7%), as well as disrespected by families (53.8%). Findings suggest that staff have foundational knowledge but lack the "how-to" or hands-on skills necessary to implement nonpharmacological behavioral management approaches and communicate with families.

Surgical anatomy of the liver, hepatic vasculature and bile ducts in the rat.
Martins, Paulo Ney Aguiar; Neuhaus, Peter
2007-04-01
The rat is the most used experimental model in surgical research. Virtually all procedures in clinical liver surgery can be performed in the rat. However, the use of the rat model in liver surgery is limited by its small size and limited knowledge of the liver anatomy. As in humans, the rat liver vasculature and biliary system have many anatomical variations. The development of surgical techniques, and the study of liver function and diseases require detailed knowledge of the regional anatomy. The objective of this study was to describe and illustrate systematically the surgical anatomy of the rat liver to facilitate the planning and performance of studies in this animal. Knowledge of the diameter and length of liver vessels is also important for the selection of catheters and perivascular devices. Twelve Wistar rat livers were dissected using a surgical microscope. Hepatic and extrahepatic anatomical structures were measured under magnification with a millimeter scale. In this study, we describe the rat liver topographical anatomy, compare it with the human liver and review the literature. Increased knowledge of the rat liver anatomy and microsurgical skills permit individualized dissection, parenchymal section, embolization and ligature of vascular and biliary branches.
Knowledge and perception of cardiovascular disease risk among patients with rheumatoid arthritis.
Boo, Sunjoo; Oh, Hyunjin; Froelicher, Erika S; Suh, Chang-Hee
2017-01-01
Patients with rheumatoid arthritis are at increased risk for cardiovascular disease. The prerequisites for reducing the risk of cardiovascular disease are adequate levels of knowledge and being aware of the risk. In this study, the levels of knowledge about cardiovascular disease among patients with rheumatoid arthritis and the perception were evaluated in relation to their actual 10-year risk of cardiovascular disease. This cross-sectional study of 200 patients with rheumatoid arthritis was conducted in a university-affiliated hospital in South Korea. The patients' actual risk of cardiovascular disease was estimated using the Framingham Risk Score. The most common risk factor was physical inactivity, with 77% of the patients not engaging in regular exercise. The patients lacked knowledge about the effects of physical inactivity and anti-inflammatory medication on the development of cardiovascular disease. Misperceptions about the risk of cardiovascular disease were common, i.e., 19.5% of the patients underestimated their risk and 41% overestimated. Hypertension, diabetes, obesity, and smoking were the most prevalent among the patients who underestimated their risk, and these same patients had the lowest level of knowledge about cardiovascular disease. This study demonstrated the rheumatoid arthritis patients' lack of knowledge about the effects of physical inactivity and anti-inflammatory medications on the development of cardiovascular disease, and their misperception of cardiovascular risk was common. As a preventive measure, educational programs about cardiovascular disease should be tailored specifically for patients with rheumatoid arthritis, and behavioral interventions, including routine exercise, should be made available at the time of diagnosis.

To assess internal medicine residents' knowledge of associations between periodontal disease and systemic illnesses, and attitudes toward patients' periodontal health. A cross-sectional survey using a self-administered questionnaire was conducted among internal medicine residents attending the Faculty of Internal Medicine 2014 Update Course organized by the National Postgraduate Medical College of Nigeria. Participants came from all over the country. Data on respondents' demographic characteristics, periodontal disease knowledge, knowledge of associations between periodontal disease and systemic illnesses, and attitudes toward patients' periodontal health were collected. Data were analyzed using Epi INFO software. The Pearson chi square test was used to measure significant association between categorical variables such as the knowledge of periodontal disease and gender, age group and designation of the participants (p ⩽ 0.05). Of 150 questionnaires distributed, 123 were returned (82% response rate); 109 questionnaires were completed properly and included in the analysis. The most common source of residents' information on oral health was television (59.4%). Only 11.2% of respondents were aware that gingival bleeding was the earliest sign of periodontal disease. Respondents correctly identified periodontal disease as a risk factor for coronary heart disease (45.9%), stroke (43.5%), hospital-acquired pneumonia (53.2%), diabetes mellitus (13.8%), and preterm birth (11%). Increased age (p = 0.032) and male gender (p = 0.022) were associated significantly with knowledge of periodontal disease as a risk factor for stroke. Higher designation (p = 0.002) and longer duration in residency training (p = 0.004) were associated significantly with knowledge of periodontal disease as risk factor for peripheral arterial disease. The majority (90.9%) of respondents had positive attitudes toward the referral of their patients for regular periodontal care. Knowledge of periodontal disease as a risk factor for systemic illnesses among medical residents in Nigeria is inadequate. These relationships should be emphasized in continuing medical education courses.

Epidemiology of yaws: an update
Kazadi, Walter M; Asiedu, Kingsley B; Agana, Nsiire; Mitjà, Oriol
2014-01-01
Yaws, a neglected tropical disease, is targeted for eradication by 2020 through large-scale mass-treatment programs of endemic communities. A key determinant for the success of the eradication campaign is good understanding of the disease epidemiology. We did a review of historical trends and new information from endemic countries, with the aim of assessing the state of knowledge on yaws disease burden. Transmission of yaws is now present in Africa, Asia, and the South Pacific. At least 12 countries are known to harbor yaws cases and 21 to 42 million people live in endemic areas. Between 2008 and 2012 more than 300,000 new cases were reported to the World Health Organization. Yaws presented high geographical variation within a country or region, high seasonality for incidence of active disease, and evidence that low standards of hygiene predispose to suffering of the disease. Key data issues include low levels of reporting, potential misdiagnosis, and scarce documentation on prevalence of asymptomatic infections. Currently available data most likely underestimates the magnitude of the disease burden. More effort is needed in order to refine accuracy of data currently being reported. A better characterization of the epidemiology of yaws globally is likely to positively impact on planning and implementation of yaws eradication. PMID:24729728

Objectives The aims were to evaluate a second phase roll-out of a dementia care training programme for general hospital staff and to further develop two outcome scales: the Confidence in Dementia scale for measuring confidence in working with people with dementia and the Knowledge in Dementia scale for measuring knowledge in dementia. Method Following a 'training the trainers' phase, the study involved the delivery of the 'Getting to Know Me' training programme to a large number of staff (n = 517) across three National Health Service (NHS) Trusts situated in North-West England. The impact of the programme was evaluated using a pre-post design which explored: (i) changes in confidence in dementia, (ii) changes in knowledge in dementia, and (iii) changes in beliefs about behaviours that challenge. Results Statistically significant change was identified between pre-post training on all outcome measures (Confidence in Dementia: eight point increase, p < 0.001; Knowledge in Dementia: two point increase p < 0.001; controllability beliefs scale: four point decrease, p < 0.001). Medium to large effect sizes were demonstrated on all outcome measures. The psychometric properties of the Confidence in Dementia and Knowledge in Dementia scales are reported. Conclusion Staff knowledge in dementia and confidence in working with people with dementia significantly increased following attendance at the training sessions. The findings are consistent with preliminary findings and strengthen current knowledge about the impact of dementia care training in general hospitals. The Confidence in Dementia and Knowledge in Dementia scales continue to demonstrate psychometrically sound properties and demonstrate utility in the field of dementia research.

The Partners in Health (PIH) scale is a measure designed to assess the generic knowledge, attitudes, behaviors, and impacts of self-management. A cross-cultural adaptation of the PIH for use in Hong Kong was evaluated in this study. This paper reports the validity and reliability of the Chinese version of PIH (C-PIH[HK]). A 12-item PIH was translated using forward-backward translation technique and reviewed by individuals with chronic diseases and health professionals. A total of 209 individuals with chronic diseases completed the scale. The construct validity, internal consistency, and test-retest reliability were evaluated in two waves. The findings in Wave 1 (n = 73) provided acceptable psychometric properties of the C-PIH(HK) but supported the adaptation of question 5 to improve the cultural relevance, validity, and reliability of the scale. An adapted version of C-PIH(HK) was evaluated in Wave 2. The findings in Wave 2 (n = 136) demonstrated good construct validity and internal consistency of C-PIH(HK). A principal component analysis with Oblimin rotation yielded a 3-factor solution, and the Cronbach's alphas of the subscales ranged from 0.773 to 0.845. Participants were asked whether they perceived the self-management workshops they attended and education provided by health professionals as useful or not. The results showed that the C-PIH(HK) was able to discriminate those who agreed and those who disagreed related to the usefulness of individual health education (p < 0.0001 in all subscales) and workshops (p < 0.001 in the knowledge subscale) as hypothesized. The test-retest reliability was high (ICC = 0.818). A culturally adapted version of PIH for use in Hong Kong was evaluated. The study supported good construct validity, discriminate validity, internal consistency, and test-retest reliability of the C-PIH(HK).

Knowledge of the distribution of arthropod vectors across a landscape is important in determining the risk for vector-borne disease. This has been well explored for ticks, but not for mosquitoes, despite their importance in the transmission of a variety of pathogens. This study examined the importance of habitat, habitat edges, and the scale at which mosquito abundance and diversity vary in a rural landscape by trapping along transects from grassland areas into forest patches. Significant patterns of vector diversity and distinct mosquito assemblages across habitats were found. The scale of individual species' responses to habitat edges was often dramatic, with several species rarely straying even 10 m from the edge. The present results suggest blood-seeking mosquito species are faithful to certain habitats, which has consequences for patterns of vector diversity and risk for pathogen transmission. This implies that analysts of risk for pathogen transmission and foci of control, and developers of land management strategies should assess habitat at a finer scale than previously considered. © 2016 The Royal Entomological Society.

Middle school students' knowledge of autism.
Campbell, Jonathan M; Barger, Brian D
2011-06-01
Authors examined 1,015 middle school students' knowledge of autism using a single item of prior awareness and a 10-item Knowledge of Autism (KOA) scale. The KOA scale was designed to assess students' knowledge of the course, etiology, and symptoms associated with autism. Less than half of students (46.1%) reported having heard of autism; however, most students correctly responded that autism was a chronic condition that was not communicable. Students reporting prior awareness of autism scored higher on 9 of 10 KOA scale items when compared to their naïve counterparts. Prior awareness of autism and KOA scores also differed across schools. A more detailed understanding of developmental changes in students' knowledge of autism should improve peer educational interventions.

Background and Objectives Policies for genetic testing in children (GTIC) focus on medical or psychosocial benefit to the child, discouraging or prohibiting carrier testing, and advising caution regarding pre-symptomatic diagnosis if no treatment exists. This study sought to understand parents’ perspectives on these issues and determine their experiences and knowledge related to genetic testing for Batten disease – a set of inherited neurodegenerative diseases of childhood onset for which no disease modifying therapies yet exist. Methods Parents of children with Batten disease completed a survey of their knowledge of genetics, experience with genetic testing, and opinions regarding GTIC. Results 54% had sought genetic testing for non-affected family members, including predictive diagnosis of healthy, at-risk children. Participation in any genetic counseling was associated with greater knowledge on questions about genetics. The majority of parents felt it was better to know ahead of time that a child would develop Batten disease, believed that this knowledge would not alter how they related to their child, and that parents should have the final say in deciding whether to obtain GTIC. Conclusions Parents of children with an inherited disease are knowledgeable about genetics and wish to establish predictive or carrier status of at-risk children. PMID:24246680

Enormous knowledge base of disease diagnosis criteria.

One of the problems in the development of the medical knowledge systems is the limitations of the system's knowledge. It is a common expectation to increase the number of diseases contained in a system. Using a high density knowledge representation method designed by us, we have developed the Enormous Knowledge Base of Disease Diagnosis Criteria (EKBDDC). It contains diagnostic criteria of 1,001 diagnostic entities and describes nearly 4,000 items of diagnostic indicators. It is the core of a huge medical project--the Electronic-Brain Medical Erudite (EBME). This enormous knowledge base was implemented initially on a low-cost popular microcomputer, which can aid in the prompting of typical disease and in teaching of diagnosis. The knowledge base is easy to expand. One of the main goals of EKBDDC is to increase the number of diseases included in it as far as possible using a low-cost computer with a comparatively small storage capacity. For this, we have designed a high density knowledge representation method. Criteria of various diagnostic entities are respectively stored in different records of the knowledge base. Each diagnostic entity corresponds to a diagnostic criterion data set; each data set consists of some diagnostic criterion data values (Table 1); each data is composed of two parts: integer and decimal; the integral part is the coding number of the given diagnostic information, and the decimal part is the diagnostic value of this information to the disease indicated by corresponding record number. For example, 75.02: the integer 75 is the coding number of "hemorrhagic skin rash"; the decimal 0.02 is the diagnostic value of this manifestation for diagnosing allergic purpura. TABULAR DATA, SEE PUBLISHED ABSTRACT. The algebraic sum method, a special form of the weighted summation, is adopted as mathematical model. In EKBDDC, the diagnostic values, which represent the significance of the disease manifestations for diagnosing corresponding diseases, were determined empirically. It is of a great economical, practical, and technical significance to realize enormous knowledge bases of disease diagnosis criteria on a low-cost popular microcomputer. This is beneficial for the developing countries to popularize medical informatics. To create the enormous international computer-aided diagnosis system, one may jointly develop the unified modules of disease diagnosis criteria used to "inlay" relevant computer-aided diagnosis systems. It is just like assembling a house using prefabricated panels.

Juvenile Idiopathic Arthritis (JIA) is a complex autoimmune rheumatic disease of largely unknown cause. Evidence is growing that epigenetic variation, particularly DNA methylation, is associated with autoimmune disease. However, nothing is currently known about the potential role of aberrant DNA methylation in JIA. As a first step to addressing this knowledge gap, we have profiled DNA methylation in purified CD4+ T cells from JIA subjects and controls. Genomic DNA was isolated from peripheral blood CD4+ T cells from 14 oligoarticular and polyarticular JIA cases with active disease, and healthy age- and sex-matched controls. Genome-scale methylation analysis was carried out using the Illumina Infinium HumanMethylation27 BeadChip. Methylation data at >25,000 CpGs was compared in a case-control study design. Methylation levels were significantly different (FDR adjusted p<0.1) at 145 loci. Removal of four samples exposed to methotrexate had a striking impact on the outcome of the analysis, reducing the number of differentially methylated loci to 11. The methotrexate-naive analysis identified reduced methylation at the gene encoding the pro-inflammatory cytokine IL32, which was subsequently replicated using a second analysis platform and a second set of case-control pairs. Our data suggests that differential T cell DNA methylation may be a feature of JIA, and that reduced methylation at IL32 is associated with this disease. Further work in larger prospective and longitudinal sample collections is required to confirm these findings, assess whether the identified differences are causal or consequential of disease, and further investigate the epigenetic modifying properties of therapeutic regimens.

Background Tuberculosis (TB) remains one of the most important infectious diseases worldwide. A comprehensive approach towards disease control that addresses social factors including stigma is now advocated. Patients with TB report fears of isolation and rejection that may lead to delays in seeking care and could affect treatment adherence. Qualitative studies have identified socio-demographic, TB knowledge, and clinical determinants of TB stigma, but only one prior study has quantified these associations using formally developed and validated stigma scales. The purpose of this study was to measure TB stigma and identify factors associated with TB stigma among patients and healthy community members. Methods A cross-sectional study was performed in southern Thailand among two different groups of participants: 480 patients with TB and 300 healthy community members. Data were collected on socio-demographic characteristics, TB knowledge, and clinical factors. Scales measuring perceived TB stigma, experienced/felt TB stigma, and perceived AIDS stigma were administered to patients with TB. Community members responded to a community TB stigma and community AIDS stigma scale, which contained the same items as the perceived stigma scales given to patients. Stigma scores could range from zero to 30, 33, or 36 depending on the scale. Three separate multivariable linear regressions were performed among patients with TB (perceived and experience/felt stigma) and community members (community stigma) to determine which factors were associated with higher mean TB stigma scores. Results Only low level of education, belief that TB increases the chance of getting AIDS, and AIDS stigma were associated with higher TB stigma scores in all three analyses. Co-infection with HIV was associated with higher TB stigma among patients. All differences in mean stigma scores between index and referent levels of each factor were less than two points, except for incorrectly believing that TB increases the chance of getting AIDS (mean difference of 2.16; 95% CI: 1.38, 2.94) and knowing someone who died from TB (mean difference of 2.59; 95% CI: 0.96, 4.22). Conclusion These results suggest that approaches addressing the dual TB/HIV epidemic may be needed to combat TB stigma and that simply correcting misconceptions about TB may have limited effects.

Sickle Cell Disease (SCD) is the commonest genetic disease worldwide. Of the sickle cell control strategies, premarital genetic counselling is increasingly practised in many countries of the world. Knowledge of the citizenry of a nation about SCD constitutes an important variable that influences the acceptability, practice and success of premarital genetic counselling. A study of students of Benue State University, Makurdi was carried out to determine their current level of knowledge. A cross sectional study involving 300 students of Benue State University, Makurdi; selected by a multistage stratified sampling technique, using self administered structured questionnaire, was carried out. Virtually all study respondents had at one time or the other heard about sickle cell disease. Based on the criteria used for knowledge scoring, less than half of the students (48%) demonstrated good knowledge. Overall Mean Score Knowledge (MSK) was 4.65 +/- 1.65. MSK was 4.58 +/- 1.66 and 4.74 +/- 1.64 for males and females respectively; there was no statistically significant difference (P > 0.05). However, having an affected relative suffering from sickle cell disease significantly influenced level of knowledge among study respondents (P < 0.05), but was not significantly associated with respondents knowing their haemoglobin phenotype. Only 141 students (47%) knew their haemoglobin phenotype. Level of knowledge about SCD did not significantly increase with age. Also, sex and religion did not significantly influence level of knowledge. The knowledge about SCD was poor and only a few knew their haemoglobin phenotype. If sickle cell disease control strategies must yield any significant results, more education about SCD, especially among students in tertiary institutions in Nigeria is recommended. The use of persons with SCD as peer educators/counsellors should be explored.

Reports on adherence among patients with rheumatoid arthritis (RA) in Egypt and the Middle East region are lacking. This study aimed to measure adherence to treatment among a sample of patients with RA at Ain Shams University Rheumatology outpatient clinic and to assess factors affecting it. A cross-sectional descriptive study was carried out at the rheumatology outpatient clinic on a sample of 140 patients with RA. An interview questionnaire was used to measure adherence using the 8-item Morisky's scale, factors affecting adherence to treatment like patients satisfaction were assessed using the short form patient satisfaction questionnaire, also patients' knowledge, beliefs and rate of prescription refilling were assessed. Disease Activity Score-28 was used as an objective method to assess RA disease activity. According to Morisky's scale, 90.6% and 9.4% were classified as low and moderately adherent, respectively, none was classified as highly adherent to treatment. Important barriers to adherence reported were fear of side effects, nonavailability of free drugs in hospital pharmacy and cost of medications. Younger patients (P=0.002) and those reporting greater general satisfaction (P=0.02) were more likely to be adherent. In addition, on-time refill rates of medication (P=0.001) and disease activity (P=0.02) were associated with higher adherence scores and thus further validated the results of the adherence questionnaire. Higher adherence was associated with more positive beliefs on medication, greater satisfaction with health care and less disease activity.

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

Patients with Alzheimer’s disease have category-specific semantic memory difficulty for natural relative to manufactured objects. We assessed the basis for this deficit by asking healthy adults and patients to judge whether pairs of words share a feature (e.g. “banana:lemon – COLOR”). In an fMRI study, healthy adults showed gray matter (GM) activation of temporal-occipital cortex (TOC) where visual-perceptual features may be represented, and prefrontal cortex (PFC) which may contribute to feature selection. Tractography revealed dorsal and ventral stream white matter (WM) projections between PFC and TOC. Patients had greater difficulty with natural than manufactured objects. This was associated with greater overlap between diseased GM areas correlated with natural kinds in patients and fMRI activation in healthy adults for natural than manufactured artifacts, and the dorsal WM projection between PFC and TOC in patients correlated only with judgments of natural kinds. Patients thus remained dependent on the same neural network as controls during judgments of natural kinds, despite disease in these areas. For manufactured objects, patients’ judgments showed limited correlations with PFC and TOC GM areas activated by controls, and did not correlate with the PFC-TOC dorsal WM tract. Regions outside of the PFC–TOC network thus may help support patients’ judgments of manufactured objects. We conclude that a large-scale neural network for semantic memory implicates both feature knowledge representations in modality-specific association cortex and heteromodal regions important for accessing this knowledge, and that patients’ relative deficit for natural kinds is due in part to their dependence on this network despite disease in these areas.

Pioneering technologies (e.g., nanotechnology, synthetic biology or climate engineering) are often associated with potential new risks and uncertainties that can become sources of controversy. The communication of information during their development and open exchanges between stakeholders is generally considered a key issue in their acceptance. While the attitudes of the public to novel technologies have been widely considered there has been relatively little investigation of the perceptions and awareness of scientists working on human or animal diseases transmitted by arthropods. Consequently, we conducted a global survey on 1889 scientists working on aspects of vector-borne diseases, exploring, under the light of a variety of demographic and professional factors, their knowledge and awareness of an emerging biotechnology that has the potential to revolutionize the control of pest insect populations. Despite extensive media coverage of key developments (including releases of manipulated mosquitoes into human communities) this has in only one instance resulted in scientist awareness exceeding 50% on a national or regional scale. We document that awareness of pioneering releases significantly relied on private communication sources that were not equally accessible to scientists from countries with endemic vector-borne diseases (dengue and malaria). In addition, we provide quantitative analysis of the perceptions and knowledge of specific biotechnological approaches to controlling vector-borne disease, which are likely to impact the way in which scientists around the world engage in the debate about their value. Our results indicate that there is scope to strengthen already effective methods of communication, in addition to a strong demand by scientists (expressed by 79.9% of respondents) to develop new, creative modes of public engagement.

Therapeutic education in diabetes helps patients take responsibility for self-control of their disease, and providing technological support systems facilitates this education. In this paper, we present an augmented reality game to support therapeutic education for patients with diabetes. Our game helps children (aged 5–14 years) to learn carbohydrate (carb) content of different foods. The game shows virtual foods on a real dish. The number of carb choices corresponding to the visualized food is also shown (1 carb choice = 10 grams of carbs). A study to determine the effectiveness of the game in terms of learning and perceived satisfaction and usability was carried out. A total of seventy children with diabetes participated in the study. From the results, we observed that the initial knowledge about carb choices of the children who participated in the study was low (a mean of 2 on a scale from 0 to 9). This indicates that therapeutic education for patients with diabetes is needed. When the results for the pre-knowledge questionnaire and the post-knowledge questionnaire were compared, it was shown that the children learned about carb choices by playing our game. We used two post-knowledge questionnaires (one post-knowledge questionnaire that contained the same foods as the pre-knowledge questionnaire and a second post-knowledge questionnaire that contained foods that were different from the ones on the pre-knowledge questionnaire). There were no statistically significant differences between these two different post-knowledge questionnaires. Moreover, the knowledge acquired was independent of gender and age. We also evaluated usability and perceived satisfaction. The children were satisfied with the game and considered that the game offers a high degree of usability. This game could be a valuable therapeutic education tool for patients with diabetes. PMID:28957355

This study was done to develop a pregnancy nutrition knowledge scale and to examine the relationships between pregnancy nutrition knowledge and eating habits in pregnant women. With convenient sampling, 189 pregnant women who used community health centers for their ante-natal care were recruited. Data were collected using a self administered questionnaire including items on pregnancy nutrition knowledge (18 items) developed by researcher and items on eating habits (14 items). Cronbach's alpha and exploratory factor analysis were examined to test reliability and construct validity of the scale. Pearson's correlation coefficients were used to identify the relationship between pregnancy nutrition knowledge and eating habits. Cronbach's alpha of 18 items was .80. In factor analysis using principal components, 6 factors explained 65% of the total variance. The level of pregnancy nutrition knowledge was not sufficient but correlations between pregnancy nutrition knowledge and some of eating habits were significant. Specifically, pregnancy nutrition knowledge was positively correlated with good eating habits and negatively with bad eating habits. The pregnancy nutrition knowledge scale developed in this study is acceptable for nutrition education led by nurses. Pregnancy nutrition knowledge and eating habits are considered as major variables for ante-natal nutrition education. In future studies, explorations are needed on dietary intake and physiological indices in pregnant women, comparison of women at risk with those not at risk, and development of nutritional education programs for pregnant women.
The Urgent Need for Robust Coral Disease Diagnostics

Coral disease has emerged over recent decades as a significant threat to coral reef ecosystems, with declines in coral cover and diversity of Caribbean reefs providing an example of the potential impacts of disease at regional scales. If similar trends are to be mitigated or avoided on reefs worldwide, a deeper understanding of the factors underlying the origin and spread of coral diseases and the steps that can be taken to prevent, control, or reduce their impacts is required. In recent years, an increased focus on coral microbiology and the application of classic culture techniques and emerging molecular technologies has revealed several coral pathogens that could serve as targets for novel coral disease diagnostic tools. The ability to detect and quantify microbial agents identified as indicators of coral disease will aid in the elucidation of disease causation and facilitate coral disease detection and diagnosis, pathogen monitoring in individuals and ecosystems, and identification of pathogen sources, vectors, and reservoirs. This information will advance the field of coral disease research and contribute knowledge necessary for effective coral reef management. This paper establishes the need for sensitive and specific molecular-based coral pathogen detection, outlines the emerging technologies that could serve as the basis of a new generation of coral disease diagnostic assays, and addresses the unique challenges inherent to the application of these techniques to environmentally derived coral samples.

Incorporating linguistic knowledge for learning distributed word representations.
Wang, Yan; Liu, Zhiyuan; Sun, Maosong
2015-01-01
Combined with neural language models, distributed word representations achieve significant advantages in computational linguistics and text mining. Most existing models estimate distributed word vectors from large-scale data in an unsupervised fashion, which, however, do not take rich linguistic knowledge into consideration. Linguistic knowledge can be represented as either link-based knowledge or preference-based knowledge, and we propose knowledge regularized word representation models (KRWR) to incorporate these prior knowledge for learning distributed word representations. Experiment results demonstrate that our estimated word representation achieves better performance in task of semantic relatedness ranking. This indicates that our methods can efficiently encode both prior knowledge from knowledge bases and statistical knowledge from large-scale text corpora into a unified word representation model, which will benefit many tasks in text mining.

2014-03-01
Questionnaires exist to assess inflammatory bowel disease (IBD)-related knowledge of adults. Owing to wording and content concerns, these were believed to be inappropriate for use in pediatric patients. The aim of this study was to develop a questionnaire to assess disease-related knowledge of pediatric patients with IBD and their parents. Following a formal process of item generation and reduction, the IBD-Knowledge Inventory Device was developed and pilot tested. It was administered to 10- to 17-year-old patients with IBD, and to 1 of each of their parents. To evaluate its discriminatory validity, pediatric residents, nurses, and ward clerks completed the questionnaire. A total of 99 patients (mean 42, Crohn disease 46, age 14(±2) years) and 99 parents completed the IBD-Knowledge Inventory Device. Parent knowledge scores, 15(±4), were higher than those of patients, 11(±4), P < 0.001. Patient and parent knowledge scores were strongly correlated (r = 0.62, P < 0.001). Patient knowledge score was significantly related to disease type (Crohn disease scored higher than ulcerative colitis, P = 0.004) and to perceived knowledge level (P < 0.001) by regression analysis. Similarly, parent knowledge score was significantly related to sex (girls scored higher, P = 0.014), postsecondary education (P < 0.001), and perceived knowledge level (P = 0.002). The questionnaire scores of 23 were 19, 16, and 10, respectively, for residents, nurses, and ward clerks. Both residents and nurses scored significantly higher than ward clerks (P = 0.001 for both). A valid IBD-related knowledge assessment questionnaire was developed for use in older children and adolescents with IBD and their parents.

The current Ebola outbreak in West Africa has already caused substantial mortality and dire human and economic consequences. It continues to represent an alarming public health threat in the region and beyond and jeopardizes the provision of health care and other services in the affected countries. The scale of the epidemic has accelerated research efforts for diagnostics, treatment, and prevention galvanized through increased availability of funding. Our knowledge relating to the virus, disease pathogenesis, risk factors, dynamics of transmission, and epidemic control is increasing, and sociocultural factors have emerged as critical determinants for the success and failure of control efforts. However, there is a long way to go. In this review we summarize the current knowledge, examine the sociocultural context in West Africa, and outline priority areas for future research.

Leptospirosis disproportionately affects residents of urban slums. To understand the knowledge, attitudes, and practices regarding leptospirosis, we conducted a cross-sectional study among residents of an urban slum community in Salvador, Brazil. Of the 257 residents who were interviewed, 225 (90%) were aware of leptospirosis and more than two-thirds of respondents correctly identified the modes of disease transmission and ways to reduce exposure. However, study participants who performed risk activities such as cleaning open sewers had limited access to protective clothing such as boots (33%) or gloves (35%). Almost all respondents performed at least one activity to prevent household rat infestation, which often included use of an illegal poison. Our findings support the need for interventions targeted at the individual and household levels to reduce risk of leptospirosis until large-scale structural interventions are available to residents of urban slum communities.

Background: Alzheimer's disease is one of the debilitating chronic diseases among older persons. It is an irreversible condition that leads to progressive deterioration of cognitive, intellectual, physical, and psychosocial functions. The study was aimed to assess the knowledge of the family members of elderly regarding Alzheimer's disease in a selected urban community at Mangalore. Materials and Methods: A preexperimental research design of one group pretest and posttest with an evaluative approach was adopted for the study. A total of 50 family members of elderly who met the inclusion criteria were selected through purposive sampling technique. The researcher developed a planned teaching program on Alzheimer's disease, and structured knowledge questionnaire on Alzheimer's disease was used to collect the data. Results: Descriptive and inferential statistics was used to analyze the data. Analysis revealed that the mean posttest knowledge (20.78 ± 3.31) was higher than mean pretest knowledge scores (12.90 ± 2.43). Significance of difference between pretest and posttest was statistically tested using paired “t” test and it was found very highly significant (t = 40.85, P < 0.05). Majority of the variables showed no significant association between pretest and posttest knowledge score and with demographic variables. Conclusion: The findings revealed that the planned teaching program is an effective strategy for improving the knowledge of the subjects. PMID:26985104

Morbidity and mortality from preventable, noncommunicable chronic disease (NCD) threatens the health of our populations and our economies. The accumulation of vast amounts of scientific knowledge has done little to change this. New and innovative thinking is essential to foster new creative approaches that leverage and integrate evidence through the support of big data, technology, and design thinking. The purpose of this paper is to summarize the results of a consensus meeting on NCD prevention sponsored by the International Olympic Committee (IOC) in April 2013. Within the context of advocacy for multifaceted systems change, the IOC's focus is to create solutions that gain traction within health care systems. The group of participants attending the meeting achieved consensus on a strategy for the prevention and management of chronic disease that includes the following: 1. Focus on behavioral change as the core component of all clinical programs for the prevention and management of chronic disease. 2. Establish actual centers to design, implement, study, and improve preventive programs for chronic disease. 3. Use human-centered design (HCD) in the creation of prevention programs with an inclination to action, rapid prototyping and multiple iterations. 4. Extend the knowledge and skills of Sports and Exercise Medicine (SEM) professionals to build new programs for the prevention and treatment of chronic disease focused on physical activity, diet, and lifestyle. 5. Mobilize resources and leverage networks to scale and distribute programs of prevention. True innovation lies in the ability to align thinking around these core strategies to ensure successful implementation of NCD prevention and management programs within health care. The IOC and SEM community are in an ideal position to lead this disruptive change. The outcome of the consensus meeting was the creation of the IOC Non-Communicable Diseases ad hoc Working Group charged with the responsibility of moving this agenda forward.

Disease knowledge, illness perceptions, and quality of life (QOL) were examined in 150 adolescents (mean age = 16.1 years, SD = 1.9; 49.3% males) with sickle cell disease (SCD). Females had higher knowledge (P = .004), lower QOL (P = .02), and perceived their illness to be more unpredictable (P = .03). Those with more severe disease perceived their illness to be unpredictable with worse outcomes. Those with higher knowledge scores perceived their illness to be chronic, made more sense of their illness, and perceived greater personal and treatment control. Final hierarchical regression model showed that secondary education as compared to primary education level (P < .001) was positively correlated whereas disease severity (P < .001), perceived unpredictability (P = .024), and negative emotions (P < .001) were negatively correlated with QOL. Health practitioners should assess adolescents’ illness perceptions and encouraging continuing schooling and addressing emotional/psychological problems could improve their QOL. PMID:29152543

The objectives were to study knowledge, attitudes, and practices (KAP) regarding tuberculosis (TB) among Somalian subjects in inner London. We administered structured, fixed response KAP questionnaires to 23 patients (culture proved TB), and two groups of controls: 25 contacts (family members) and 27 lay controls (general Somali immigrant population). Responses were summed on a five-point scale. Most were aware of the infectious nature of TB but uncertain of other risk factors. Many were uncertain about coping with the disease and its effect on lifestyle. Belief in biomedicine for TB was unequivocal with men having a significantly higher belief score than women (p = 0.02); the need to comply with TB medication was unambiguously understood. Somalians interviewed were educated, multilingual, and aware of important health issues. Uncertainties in core TB knowledge need to be addressed with direct educational input, especially in women and recent entrants into the country. Volunteers from the established Somalian community could play a valuable part as links in the community to fight TB.

Despite the unprecedented and increasing amount of data, relatively little progress has been made in molecular characterization of mechanisms underlying Parkinson's disease. In the area of Parkinson's research, there is a pressing need to integrate various pieces of information into a meaningful context of presumed disease mechanism(s). Disease ontologies provide a novel means for organizing, integrating, and standardizing the knowledge domains specific to disease in a compact, formalized and computer-readable form and serve as a reference for knowledge exchange or systems modeling of disease mechanism. The Parkinson's disease ontology was built according to the life cycle of ontology building. Structural, functional, and expert evaluation of the ontology was performed to ensure the quality and usability of the ontology. A novelty metric has been introduced to measure the gain of new knowledge using the ontology. Finally, a cause-and-effect model was built around PINK1 and two gene expression studies from the Gene Expression Omnibus database were re-annotated to demonstrate the usability of the ontology. The Parkinson's disease ontology with a subclass-based taxonomic hierarchy covers the broad spectrum of major biomedical concepts from molecular to clinical features of the disease, and also reflects different views on disease features held by molecular biologists, clinicians and drug developers. The current version of the ontology contains 632 concepts, which are organized under nine views. The structural evaluation showed the balanced dispersion of concept classes throughout the ontology. The functional evaluation demonstrated that the ontology-driven literature search could gain novel knowledge not present in the reference Parkinson's knowledge map. The ontology was able to answer specific questions related to Parkinson's when evaluated by experts. Finally, the added value of the Parkinson's disease ontology is demonstrated by ontology-driven modeling of PINK1 and re-annotation of gene expression datasets relevant to Parkinson's disease. Parkinson's disease ontology delivers the knowledge domain of Parkinson's disease in a compact, computer-readable form, which can be further edited and enriched by the scientific community and also to be used to construct, represent and automatically extend Parkinson's-related computable models. A practical version of the Parkinson's disease ontology for browsing and editing can be publicly accessed at http://bioportal.bioontology.org/ontologies/PDON .
Effect of Gender on the Knowledge of Medicinal Plants: Systematic Review and Meta-Analysis
Torres-Avilez, Wendy; de Medeiros, Patrícia Muniz
2016-01-01
Knowledge of medicinal plants is not only one of the main components in the structure of knowledge in local medical systems but also one of the most studied resources. This study uses a systematic review and meta-analysis of a compilation of ethnobiological studies with a medicinal plant component and the variable of gender to evaluate whether there is a gender-based pattern in medicinal plant knowledge on different scales (national, continental, and global). In this study, three types of meta-analysis are conducted on different scales. We detect no significant differences on the global level; women and men have the same rich knowledge. On the national and continental levels, significant differences are observed in both directions (significant for men and for women), and a lack of significant differences in the knowledge of the genders is also observed. This finding demonstrates that there is no gender-based pattern for knowledge on different scales. PMID:27795730

This paper reports a study testing the content and face validity and internal consistency of the Dutch version of the Aging Sexual Knowledge and Attitudes Scale. The ability of older residents to sexually express themselves is known to be influenced by the knowledge and attitudes of nursing home staff towards later-life sexuality. Although the Aging Sexual Knowledge and Attitudes Scale is a widely used instrument to measure this, there is no validated, Dutch translation available. Instrument development. Following a standard forward/backward translation into Dutch, the scale was further adapted for use in Flemish nursing home settings. Content and face validity and user-friendliness were assessed. The psychometric properties were determined by means of an exploratory study. Data were collected from March-April 2011 at eight Flemish nursing homes. Reliability was assessed using internal consistency and item-total correlations. Both subscales of the Flemish adaptation showed acceptable content validity. The face validity and user-friendliness were deemed favourable with hardly any remarks given by the expert panel. The Cronbach's α was 0.80 and 0.88 for the knowledge and attitude subscales, respectively. The item-total correlations ranged from 0.21-0.48 for the knowledge section and from 0.09-0.68 for the attitude subscale. We conclude from our study that the Dutch version of the scale has acceptable to good psychometric properties. The Flemish adaptation therefore seems to be a valuable instrument for studying nursing staff's knowledge and attitudes towards aged sexuality in Flanders. © 2013 Blackwell Publishing Ltd.
Systematic review of atorvastatin for the treatment of Alzheimer's disease★
Sun, Yuan; Wang, Genfa; Pan, Zhihong; Chen, Shuyan
2012-01-01
Objective: To assess the clinical efficacy and safety of atorvastatin in the treatment of Alzheimer's disease. Data Sources: Medline (1948/2011-04), Embase (1966/2011-04), Cochrane Library (Issue 3, 2011), Chinese National Knowledge Infrastructure (1989/2011-04), and the Chinese Biomedical Literature Database (1979/2011-04) were searched for randomized clinical trials regardless of language. Abstracts of conference papers were manually searched. Furthermore, Current Controlled Trials (http://controlled-trials.com), Clinical Trials.gov (http://clinicaltrials.gov), and Chinese Clinical Trial Registry (http://www.chictr.org) were also searched. Key words included Alzheimer disease, dementia, cognition, affection, memory dysfunction, hydroxymethylglutaryl-CoA reductase inhibitors, atorvastatin and statins. Data Selection: Randomized controlled trials of grade A or B according to quality evaluation criteria of the Cochrane Collaboration were selected, in which atorvastatin and placebo were used to evaluate the effects of atorvastatin in the treatment of Alzheimer's disease. Study methodological quality was evaluated based on criteria described in Cochrane Reviewer's Handbook 5.0.1. Revman 5.1 software was used for data analysis. Main Outcome Measures: Clinical efficacy, safety, withdrawal from the studies, and withdrawal due to adverse effects. Results: Two randomized controlled trials were included, one was scale A, and the other was scale B. All patients (n = 710, age range 50–90 years) were diagnosed as probable or possible mild to moderate Alzheimer's disease according to standard criteria and treated with atorvastatin 80 mg/d or placebo. There was no difference between the two groups in the final follow-up for Clinical Global Impression of Change scale (WMD = 0.13, 95%CI: –0.15 to 0.40), the Alzheimer's Disease Assessment Scale-cognitive subscale (WMD = 1.05, 95%CI: –3.06 to 6.05), Mini-Mental State Examination Scale (WMD = 0.77, 95%CI: –0.57 to 2.10), and the Neuropsychiatric Instrument (WMD = 2.07, 95%CI: –1.59 to 5.73). The rates of abnormal liver function, withdrawal from treatment, and withdrawal due to adverse effects were higher in the treatment group (OR = 7.86, 95%CI: 2.50-24.69; OR = 4.70, 95%CI: 2.61-8.44; and OR = 5.47, 95%CI: 3.01-9.94; respectively) compared with the placebo group. Conclusion: There is insufficient evidence to recommend atorvastatin for the treatment of mild to moderate Alzheimer's disease, because there was no benefit on general function, cognitive function or mental/behavior abnormality outcome measures. Efficacy and safety need to be confirmed by larger and higher quality randomized controlled trials, especially for moderate to severe Alzheimer's disease, because results of this systematic review may be limited by selection bias, implementation bias, as well as measurement bias.

The recent discovery of large-scale arsenic (As) contamination of groundwater has raised much concern in Bangladesh. Reliable estimates of the magnitude of As exposure and related health problems have not been comprehensively investigated in Bangladesh. A large population-based study on As and health consequences in Matlab (AsMat) was done in Matlab field site where International Centre for Diarrhoeal Disease Research, Bangladesh has maintained a health and demographic surveillance system registering prospectively all vital events. Taking advantage of the health and demographic surveillance system and collecting data on detailed individual level As exposure using water and urine samples, AsMat investigated the morbidity and mortality associated with As exposure. Reviews of findings to date suggest the adverse effects of As exposure on the risk of skin lesions, high blood pressure, diabetes mellitus, chronic disease, and all-cause infant and adult disease mortality. Future studies of clinical endpoints will enhance our knowledge gaps and will give directions for disease prevention and mitigations. Copyright © 2011. Published by Elsevier B.V.

I offer a critical perspective on a large-scale population study on gene-environment interactions and common diseases proposed by the US Secretary of Health and Human Services' Advisory Committee on Genetics, Health, and Society (SACGHS). I argue that for scientific and policy reasons this and similar studies have little to add to current knowledge about how to prevent, treat, or decrease inequalities in common diseases, all of which are major claims of the proposal. I use diabetes as an exemplar of the diseases that the study purports to illuminate. I conclude that the question is not whether the study will meet expectations or whether the current emphasis on a genetic paradigm is real or imagined, desirable or not. Rather, the question is why, given the flaws of the science underwriting the study, its assumptions remain unchallenged. Future research should investigate the reasons for this immunity from criticism and for the popularity of this and similar projects among laypersons as well as among intellectuals.
Pain in Neurodegenerative Disease: Current Knowledge and Future Perspectives
de Tommaso, Marina; Arendt-Nielsen, Lars; Defrin, Ruth; Kunz, Miriam; Pickering, Gisele; Valeriani, Massimiliano
2016-01-01
Neurodegenerative diseases are going to increase as the life expectancy is getting longer. The management of neurodegenerative diseases such as Alzheimer's disease (AD) and other dementias, Parkinson's disease (PD) and PD related disorders, motor neuron diseases (MND), Huntington's disease (HD), spinocerebellar ataxia (SCA), and spinal muscular atrophy (SMA), is mainly addressed to motor and cognitive impairment, with special care to vital functions as breathing and feeding. Many of these patients complain of painful symptoms though their origin is variable, and their presence is frequently not considered in the treatment guidelines, leaving their management to the decision of the clinicians alone. However, studies focusing on pain frequency in such disorders suggest a high prevalence of pain in selected populations from 38 to 75% in AD, 40% to 86% in PD, and 19 to 85% in MND. The methods of pain assessment vary between studies so the type of pain has been rarely reported. However, a prevalent nonneuropathic origin of pain emerged for MND and PD. In AD, no data on pain features are available. No controlled therapeutic trials and guidelines are currently available. Given the relevance of pain in neurodegenerative disorders, the comprehensive understanding of mechanisms and predisposing factors, the application and validation of specific scales, and new specific therapeutic trials are needed.

Genetic testing in cardiovascular diseases.
Arndt, Anne-Karin; MacRae, Calum A
2014-05-01
The review is designed to outline the major developments in genetic testing in the cardiovascular arena in the past year or so. This is an exciting time in genetic testing as whole exome and whole genome approaches finally reach the clinic. These new approaches offer insight into disease causation in families in which this might previously have been inaccessible, and also bring a wide range of interpretative challenges. Among the most significant recent findings has been the extent of physiologic rare coding variation in the human genome. New disease genes have been identified through whole exome studies in neonatal arrhythmia, congenital heart disease and coronary artery disease that were simply inaccessible with other techniques. This has not only shed light on the challenges of genetic testing at this scale, but has also sharply defined the limits of prior gene-panel focused testing. As novel therapies targeting specific genetic subsets of disease become available, genetic testing will become a part of routine clinical care. The pace of change in sequencing technologies has begun to transform clinical medicine, and cardiovascular disease is no exception. The complexity of such studies emphasizes the importance of real-time communication between the genetics laboratory and genetically informed clinicians. New efforts in data and knowledge management will be central to the continued advancement of genetic testing.
Application of statistical mining in healthcare data management for allergic diseases

Wawrzyniak, Zbigniew M.; Martínez Santolaya, Sara
2014-11-01
The paper aims to discuss data mining techniques based on statistical tools in medical data management in case of long-term diseases. The data collected from a population survey is the source for reasoning and identifying disease processes responsible for patient's illness and its symptoms, and prescribing a knowledge and decisions in course of action to correct patient's condition. The case considered as a sample of constructive approach to data management is a dependence of allergic diseases of chronic nature on some symptoms and environmental conditions. The knowledge summarized in a systematic way as accumulated experience constitutes to an experiential simplified model of the diseases with feature space constructed of small set of indicators. We have presented the model of disease-symptom-opinion with knowledge discovery for data management in healthcare. The feature is evident that the model is purely data-driven to evaluate the knowledge of the diseases` processes and probability dependence of future disease events on symptoms and other attributes. The example done from the outcomes of the survey of long-term (chronic) disease shows that a small set of core indicators as 4 or more symptoms and opinions could be very helpful in reflecting health status change over disease causes. Furthermore, the data driven understanding of the mechanisms of diseases gives physicians the basis for choices of treatment what outlines the need of data governance in this research domain of discovered knowledge from surveys.

This paper describes details of four scales of a questionnaire—“Computers in Medical Care”—measuring attributes of computer use, self-reported computer knowledge, computer feature demand, and computer optimism of academic physicians. The reliability (i.e., precision, or degree to which the scale's result is reproducible) and validity (i.e., accuracy, or degree to which the scale actually measures what it is supposed to measure) of each scale were examined by analysis of the responses of 771 full-time academic physicians across four departments at five academic medical centers in the United States. The objectives of this paper were to define the psychometric properties of the scales as the basis for a future demonstration study and, pending the results of further validity studies, to provide the questionnaire and scales to the medical informatics community as a tool for measuring the attitudes of health care providers. Methodology: The dimensionality of each scale and degree of association of each item with the attribute of interest were determined by principal components factor analysis with othogonal varimax rotation. Weakly associated items (factor loading <.40) were deleted. The reliability of each resultant scale was computed using Cronbach's alpha coefficient. Content validity was addressed during scale construction; construct validity was examined through factor analysis and by correlational analyses. Results: Attributes of computer use, computer knowledge, and computer optimism were unidimensional, with the corresponding scales having reliabilities of.79,.91, and.86, respectively. The computer-feature demand attribute differentiated into two dimensions: the first reflecting demand for high-level functionality with reliability of.81 and the second demand for usability with reliability of.69. There were significant positive correlations between computer use, computer knowledge, and computer optimism scale scores and respondents' hands-on computer use, computer training, and self-reported computer sophistication. In addition, items posited on the computer knowledge scale to be more difficult generated significantly lower scores. Conclusion: The four scales of the questionnaire appear to measure with adequate reliability five attributes of academic physicians' attitudes toward computers in medical care: computer use, self-reported computer knowledge, demand for computer functionality, demand for computer usability, and computer optimism. Results of initial validity studies are positive, but further validation of the scales is needed. The URL of a downloadable HTML copy of the questionnaire is provided. PMID:9524349

To determine whether playing a simple CD-ROM educational game (developed specifically for children with sickle cell disease), improved children's knowledge and confidence in selected symptom management and practice. Twenty-two eligible children completed a pretest to determine knowledge and confidence levels, played the Sickle Cell Slime-O-Rama Game, then completed an identical posttest. Significant increases in knowledge (t = 2.828, p =.010) and confidence (t = 3.759, p =.001) levels between pre- and posttests were identified. It is promising that a simple, interacting CD-ROM game allowed children with sickle cell disease to quickly acquire knowledge about the disease and symptom management, and increased their confidence to apply this new knowledge. Results suggest the high utility of this tailored game to foster active self-management behaviors in this population.
Seborrheic Dermatitis and Dandruff: A Comprehensive Review

Seborrheic Dermatitis (SD) and dandruff are of a continuous spectrum of the same disease that affects the seborrheic areas of the body. Dandruff is restricted to the scalp, and involves itchy, flaking skin without visible inflammation. SD can affect the scalp as well as other seborrheic areas, and involves itchy and flaking or scaling skin, inflammation and pruritus. Various intrinsic and environmental factors, such as sebaceous secretions, skin surface fungal colonization, individual susceptibility, and interactions between these factors, all contribute to the pathogenesis of SD and dandruff. In this review, we summarize the current knowledge on SD and dandruff, including epidemiology, burden of disease, clinical presentations and diagnosis, treatment, genetic studies in humans and animal models, and predisposing factors. Genetic and biochemical studies and investigations in animal models provide further insight on the pathophysiology and strategies for better treatment. PMID:27148560
Global cancer research initiative
Love, Richard R
2010-01-01
Cancer is an increasing problem for low- and middle-income countries undergoing an epidemiologic transition from dominantly acute communicable disease to more frequent chronic disease with increased public health successes in the former domain. Progress against cancer in high-income countries has been modest and has come at enormous expense. There are several well-conceived global policy and planning initiatives which, with adequate political will, can favorably impact the growing global cancer challenges. Most financial resources for cancer, however, are spent on diagnosis and management of patients with disease in circumstances where specific knowledge about effective approaches is significantly limited, and the majority of interventions, other than surgery, are not cost-effective in resource-limited countries by global standards. In summary, how to intervene effectively on a global scale for the majority of citizens who develop cancer is poorly defined. In contrast to technology-transfer approaches, markedly increased clinical research activities are more likely to benefit cancer sufferers. In these contexts, a global cancer research initiative is proposed, and mechanisms for realizing such an effort are suggested. PMID:21188101

The last 20 years of advancement in sequencing technologies have led to sequencing thousands of microbial genomes, creating mountains of genetic data. While efficiency in generating the data improves almost daily, applying meaningful relationships between taxonomic and genetic entities on this scale requires a structured and integrative approach. Currently, knowledge is distributed across a fragmented landscape of resources from government-funded institutions such as National Center for Biotechnology Information (NCBI) and UniProt to topic-focused databases like the ODB3 database of prokaryotic operons, to the supplemental table of a primary publication. A major drawback to large scale, expert-curated databases is the expense of maintaining and extending them over time. No entity apart from a major institution with stable long-term funding can consider this, and their scope is limited considering the magnitude of microbial data being generated daily. Wikidata is an openly editable, semantic web compatible framework for knowledge representation. It is a project of the Wikimedia Foundation and offers knowledge integration capabilities ideally suited to the challenge of representing the exploding body of information about microbial genomics. We are developing a microbial specific data model, based on Wikidata's semantic web compatibility, which represents bacterial species, strains and the gene and gene products that define them. Currently, we have loaded 43,694 gene and 37,966 protein items for 21 species of bacteria, including the human pathogenic bacteriaChlamydia trachomatis.Using this pathogen as an example, we explore complex interactions between the pathogen, its host, associated genes, other microbes, disease and drugs using the Wikidata SPARQL endpoint. In our next phase of development, we will add another 99 bacterial genomes and their gene and gene products, totaling ∼900,000 additional entities. This aggregation of knowledge will be a platform for community-driven collaboration, allowing the networking of microbial genetic data through the sharing of knowledge by both the data and domain expert. © The Author(s) 2016.

Osteogenesis imperfecta, also known as 'brittle bone disease', is a genetic connective tissue disease. It is characterized by bone fragility and osteopenia (low bone density). In this case, a 57-year old female presented to the University Hospital of the West Indies (UHWI), Physical Medicine and Rehabilitation Clinic with left low back pain rated 6/10 on the numeric rating scale (NRS). Clinically, the patient had sacroiliac joint mediated pain although X-rays did not show the sacroiliac joint changes. Fluoroscopy-guided left sacroiliac joint steroid injection was done. Numeric rating scale and Oswestry Disability Index (ODI) questionnaire were used to evaluate outcome. This was completed at baseline, one week follow-up and at eight weeks post fluoroscopy-guided sacroiliac joint steroid injection. Numeric rating scale improved from 6/10 before the procedure to 0/10 post procedure, and ODI questionnaire score improved from a moderate disability score of 40% to a minimal disability score of 13%. Up to eight weeks, the NRS was 0/10 and ODI remained at minimal disability of 15%. Fluoroscopy-guided sacroiliac joint injection is a known diagnostic and treatment method for sacroiliac joint mediated pain. To our knowledge, this is the first case published on the use of fluoroscopy-guided sacroiliac joint steroid injection in the treatment of sacroiliac joint mediated low back pain in a patient with osteogenesis imperfecta.

To review and summarize the current knowledge regarding the outcome measures used to evaluate scoliosis surgery. Literature review. Outcome instruments should be tested to ensure that they have adequate metric characteristics: content and construct validity, reliability, and responsiveness. In the evaluation of scoliosis, generic instruments to assess health-related quality of life (HRQL) have been used, such as the SF-36 questionnaire and the EuroQol5D instrument. Nonetheless, it is preferable to use disease-specific instruments for this purpose, such as the SRS-22 Patient Questionnaire and the quality of life profile for spinal deformities (QLPSD). More recently, these generic and disease-specific instruments have been complemented with the use of super-specific instruments; i.e., those assessing a single aspect of the condition or specific populations with the condition. The patients' perception of their trunk deformity and body image has received particular attention, and several instruments are available to evaluate these aspects, such as the Walter-Reed Visual Assessment Scale (WRVAS), the Spinal Appearance Questionnaire (SAQ), and the Trunk Appearance Perception Scale (TAPS). The impacts of brace use can also be measured with specific scales, including the Bad Sobernheim Stress Questionnaire (BSSQ) and the Brace Questionnaire (BrQ). The available instruments to evaluate the treatment for non-idiopathic scoliosis have not been sufficiently validated and analyzed. Evaluation of scoliosis treatment should include the patient's perspective, which can be obtained with the use of patient-reported outcome measures.
Physician Knowledge of Chagas Disease in Hispanic Immigrants Living in Appalachian Ohio.
Amstutz-Szalay, Shelley
2017-06-01
Studies have indicated that US physicians may not consider Chagas disease when diagnosing immigrant patients from Chagas-endemic areas. The purpose of this study was to evaluate physician knowledge of Chagas disease in six Appalachian Ohio counties. Physician knowledge was assessed by self-administrated survey (n = 105). Over 80 % of physicians reported that their current knowledge of Chagas disease was limited or very limited, and 50 % reported never considering Chagas disease diagnosis for their at-risk patients. Nearly 70 % of physicians were unaware of the percentage of chronic Chagas patients that develop clinical disease, and 36 % could not correctly identify the disease course. In addition, over 30 % of physicians reported that no services were available within their practice to assist Spanish-speaking patients with limited English proficiency. A lack of physician awareness of Chagas disease, coupled with a lack of translation services, may create a barrier to care by decreasing the likelihood of identification of patients at risk for Chagas disease. The results of this study support the need for interventions to ensure proper diagnosis and treatment of Chagas disease in Hispanic immigrants in rural Appalachian Ohio.

To investigate the effects of a knowledge-attitude-behaviour health education model on acquisition of disease-related knowledge and self-management behaviour by patients undergoing maintenance haemodialysis. Patients recently prescribed MHD were randomly assigned to a control group or an intervention group. Control group patients were treated with usual care and general education models. A specialist knowledge-attitude-behaviour health education model was applied to patients in the intervention group. Eighty-six patients were included (n = 43 per group). Before intervention, there were no significant between-group differences in disease knowledge and self-management behaviour. After 6 months' intervention, a significant between-group difference in acquisition of disease knowledge was observed. Self-management behaviour scores (control of body mass, reasonable diet, correct drug intake, physical activity, correct fistula care, disease condition monitoring, psychological and social behaviours) for the intervention group were also higher than those for the control group. These preliminary findings suggest that the knowledge-attitude-behaviour model appears to be a valuable tool for the health education of MHD patients. © The Author(s) 2016.

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 present study was conducted to assess knowledge and attitude of unmarried female students in King Abdul-Aziz University (KAU) towards premarital screening (PMS) program, to determine predictors of high students' knowledge scores and to improve their knowledge about PMS through conduction of an educational campaign. Multi-stage stratified random sample method was used with recruitment of 1563 students from all faculties of KAU, during the educational year 2008-2009. The Pre-test included 30 knowledge items and 14 attitude statements with student's response through a 5-point Likert scale. Health education was conducted using audiovisual aids through pre-designed educational materials. Statistical analysis was done by SPSS version 16. Students' knowledge about the program was generally low before the educational campaign. The predictors of high knowledge scores were being a health science student (aOR=4.15; 95% CI: 2.97-5.81), age ≥20 years (aOR=2.78; 95% CI: 2.01-3.85), family history of hereditary diseases and income ≥10,000 SR/month. Regarding attitude, almost all students (99.0%) agreed on the importance of PMS. After the educational program, students' knowledge about PMS was markedly improved. The mean students' knowledge score was 9.85 ± 5.36 in Pre-test and improved to 18.45 ± 4.96 in Post-test, with a highly statistical significant difference (paired t=25.40, p<0.000). The educational program was successful in improving students' knowledge about the PMS. Conduction of similar educational programs and adding PMS in the curriculum of secondary and university education are recommended.

Advanced directives documents (ADD), allow respect and know patient's intentions in health matters, when they are not able by themselves, for decision making. The aim of this study is making a valoration of the knowledgment of this documents in human immunodeficiency virus (HIV) infected patients, as well as their own knowledgment about this patology and possible complications. HIV infected patients controlled in 2 centers (Hospital de Mataró and Hospital de Granollers). Plained interview as a questinonary, that permits evaluate: own knowledge of the patology, received medical information level of satisfaction, patient s medical decision making involving desire, aptitudes in front of different hypothetical health status, and ADD knowledge. Factors associated to both knowledges (patology and ADD) are also evaluated. 74.3% of the interviewed patients, showed a good patology knowledge. This result was associated with: youth, less functional level according to Karnofsky's scale, subjective perception on severity, previous admission at an intensive care unit, chronic hepatopathy, and previous parenteral drugs addiction. In the same way was associated with the negative to depend of mechanical ventilation or another people, and not being uncomfortable talking about this subjects. ADD's knowledge was relationated with the fact of being female (42.0% vs 26.8%; p = 0.024), higher academic formation (55.1% vs 25.5%; p < 0.001) and belief that medical decision making must be done by themselves (78.3% vs 53.6%; p = 0.002). Patology understanding and its complications, may be considered optimal in HIV population. One third of this group, has a good knowledge of ADDs, and is directly relationated with female sex, academic level, and clinical decisions making implication by the patients.

Diabetes is a significant global public health concern. Poor knowledge of disease and healthcare utilization is associated with worse health outcomes, leading to increasing burden of diabetes in many developing countries. This study aimed to determine diabetes related knowledge and factors affecting utilization of healthcare services among patients with type 2 diabetes mellitus in Bangladesh. This analytical study was conducted among 318 patients with type 2 diabetes (T2DM) attending two large tertiary hospitals in Dhaka, Bangladesh between August 2014 and January 2015. Interviewer assisted semi-structured survey questionnaire was used to collect data on diabetes knowledge (measured by a validated Likert scale) and self-reported utilization of service for diabetes. Univariate and bivariate analyses were conducted to determine the factors associated with diabetes knowledge and healthcare utilization. The mean (±SD) age of participants was 52 (±10) years. Majority of the participants were females (58%) and urban residents (74%). Almost two-third (66%) of the participants had an average level of knowledge of T2DM. One-fifth (21%) of the participants had poor knowledge which was significantly associated with gender (P < 0.002), education (P < 0 .001) and income (P < 0.001). The median travel and waiting time at the facility was 30 and 45 min respectively. More than one-third (37%) of the participants checked their blood glucose monthly. Most patients were satisfied regarding the family (55%) and hospital (67%) support. T2DM patients had average knowledge of diabetes which might affect the utilization of healthcare services for diabetes management. Innovations in increasing diabetes knowledge and health behavior change are recommended specially for females, those with lower education and less income.

To describe the development, implementation, and assessment of an advanced elective course on infectious diseases using active-learning strategies. Pedagogy for active learning was incorporated by means of mini-lecture, journal club, and debate with follow-up discussion. Forty-eight students were enrolled in this 4-week elective course, in which 30% of course time was allocated for active-learning exercises. All activities were fundamentally designed as a stepwise approach in complementing each active-learning exercise. Achievement of the course learning objectives was assessed using a 5-point Likert scale survey instrument. Students' awareness of the significance of antimicrobial resistance was improved (p ≤ 0.05). Students' ability to critically evaluate the infectious-disease literature and its application in informed clinical judgments was also enhanced through these active-learning exercises (p ≤ 0.05). Students agreed that active learning should be part of the pharmacy curriculum and that active-learning exercises improved their critical-thinking, literature-evaluation, and self-learning skills. An elective course using active-learning strategies allowed students to combine information gained from the evaluation of infectious-disease literature, critical thinking, and informed clinical judgment. This blended approach ultimately resulted in an increased knowledge and awareness of infectious diseases.

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.

This article reports the validation of an assessment instrument designed to measure the outcomes of training in evidence-based practice (EBP) in the context of dentistry. Four EBP dimensions are measured by this instrument: 1) understanding of EBP concepts, 2) attitudes about EBP, 3) evidence-accessing methods, and 4) confidence in critical appraisal. The instrument-the Knowledge, Attitudes, Access, and Confidence Evaluation (KACE)-has four scales, with a total of thirty-five items: EBP knowledge (ten items), EBP attitudes (ten), accessing evidence (nine), and confidence (six). Four elements of validity were assessed: consistency of items within the KACE scales (extent to which items within a scale measure the same dimension), discrimination (capacity to detect differences between individuals with different training or experience), responsiveness (capacity to detect the effects of education on trainees), and test-retest reliability. Internal consistency of scales was assessed by analyzing responses of second-year dental students, dental residents, and dental faculty members using Cronbach coefficient alpha, a statistical measure of reliability. Discriminative validity was assessed by comparing KACE scores for the three groups. Responsiveness was assessed by comparing pre- and post-training responses for dental students and residents. To measure test-retest reliability, the full KACE was completed twice by a class of freshman dental students seventeen days apart, and the knowledge scale was completed twice by sixteen faculty members fourteen days apart. Item-to-scale consistency ranged from 0.21 to 0.78 for knowledge, 0.57 to 0.83 for attitude, 0.70 to 0.84 for accessing evidence, and 0.87 to 0.94 for confidence. For discrimination, ANOVA and post hoc testing by the Tukey-Kramer method revealed significant score differences among students, residents, and faculty members consistent with education and experience levels. For responsiveness to training, dental students and residents demonstrated statistically significant changes, in desired directions, from pre- to post-test. For the student test-retest, Pearson correlations for KACE scales were as follows: knowledge 0.66, attitudes 0.66, accessing evidence 0.74, and confidence 0.76. For the knowledge scale test-retest by faculty members, the Pearson correlation was 0.79. The construct validity of the KACE is equivalent to that of instruments that assess similar EBP dimensions in medicine. Item consistency for the knowledge scale was more variable than for other KACE scales, a finding also reported for medically oriented EBP instruments. We conclude that the KACE has good discriminative validity, responsiveness to training effects, and test-retest reliability.

The Centre for Therapeutic Target Validation (CTTV - https://www.targetvalidation.org/) was established to generate therapeutic target evidence from genome-scale experiments and analyses. CTTV aims to support the validity of therapeutic targets by integrating existing and newly-generated data. Data integration has been achieved in some resources by mapping metadata such as disease and phenotypes to the Experimental Factor Ontology (EFO). Additionally, the relationship between ontology descriptions of rare and common diseases and their phenotypes can offer insights into shared biological mechanisms and potential drug targets. Ontologies are not ideal for representing the sometimes associated type relationship required. This work addresses two challenges; annotation of diverse big data, and representation of complex, sometimes associated relationships between concepts. Semantic mapping uses a combination of custom scripting, our annotation tool 'Zooma', and expert curation. Disease-phenotype associations were generated using literature mining on Europe PubMed Central abstracts, which were manually verified by experts for validity. Representation of the disease-phenotype association was achieved by the Ontology of Biomedical AssociatioN (OBAN), a generic association representation model. OBAN represents associations between a subject and object i.e., disease and its associated phenotypes and the source of evidence for that association. The indirect disease-to-disease associations are exposed through shared phenotypes. This was applied to the use case of linking rare to common diseases at the CTTV. EFO yields an average of over 80% of mapping coverage in all data sources. A 42% precision is obtained from the manual verification of the text-mined disease-phenotype associations. This results in 1452 and 2810 disease-phenotype pairs for IBD and autoimmune disease and contributes towards 11,338 rare diseases associations (merged with existing published work [Am J Hum Genet 97:111-24, 2015]). An OBAN result file is downloadable at http://sourceforge.net/p/efo/code/HEAD/tree/trunk/src/efoassociations/. Twenty common diseases are linked to 85 rare diseases by shared phenotypes. A generalizable OBAN model for association representation is presented in this study. Here we present solutions to large-scale annotation-ontology mapping in the CTTV knowledge base, a process for disease-phenotype mining, and propose a generic association model, 'OBAN', as a means to integrate disease using shared phenotypes. EFO is released monthly and available for download at http://www.ebi.ac.uk/efo/.

The use of generic medicines is a cost-effective policy, often dictated by fiscal restraints. To our knowledge, no fully validated tool exploring the students' knowledge and attitudes towards generic medicines exists. The aim of our study was to develop and validate a questionnaire exploring the knowledge and attitudes of M.Sc. in Health Care Management students and recent alumni's towards generic drugs in Greece. The development of the questionnaire was a result of literature review and pilot-testing of its preliminary versions to researchers and students. The final version of the questionnaire contains 18 items measuring the respondents' knowledge and attitude towards generic medicines on a 5-point Likert scale. Given the ordinal nature of the data, ordinal alpha and polychoric correlations were computed. The sample was randomly split into two halves. Exploratory factor analysis, performed in the first sample, was used for the creation of multi-item scales. Confirmatory factor analysis and Generalized Linear Latent and Mixed Model analysis (GLLAMM) with the use of the rating scale model were used in the second sample to assess goodness of fit. An assessment of internal consistency reliability, test-retest reliability, and construct validity was also performed. Among 1402 persons contacted, 986 persons completed our questionnaire (response rate = 70.3%). Overall Cronbach's alpha was 0.871. The conjoint use of exploratory and confirmatory factor analysis resulted in a six-scale model, which seemed to fit the data well. Five of the six scales, namely trust, drug quality, state audit, fiscal impact and drug substitution were found to be valid and reliable, while the knowledge scale suffered only from low inter-scale correlations and a ceiling effect. However, the subsequent confirmatory factor and GLLAMM analyses indicated a good fit of the model to the data. The ATTOGEN instrument proved to be a reliable and valid tool, suitable for assessing students' knowledge and attitudes towards generic medicines.

Psychoeducational activities are a way of promoting help for caregivers of patients with Alzheimer’s disease, representing a forum for knowledge sharing, and in which the primary focus is on psychological themes aimed at carers developing coping skills and strategies. Objective The main objective of this study was to gauge perceptions about care and its impact among family caregivers of patients with AD participating in a psychoeducational group intervention, as well as the possible positive and negative aspects associated with this role. The subjective impact of AD on the lives of these caregivers was assessed on each of the dimensions of the Caregiver Burden Scale using a semi-directed interview on perceptions about care. Methods This was a prospective study, in which information was collected twice, before and after, psychoeducational intervention. Through the application of the scale, benefits were evident for all dimensions assessed in the instrument (general strain, isolation, disappointment, emotional involvement and environment). Results The results showed that after the psychoeducational intervention, caregivers felt less burdened by care compared to pre-intervention. Conclusion: These findings confirm that expanded implementation of psychoeducational interventions for caregivers of patients with AD can be beneficial for both caregivers and patients. PMID:29213748

The nematode Xiphinema index is, economically, the major virus vector in viticulture, transmitting specifically the Grapevine fanleaf virus (GFLV), the most severe grapevine virus disease worldwide. Increased knowledge of the spatial distribution of this nematode, both horizontally and vertically, and of correlative GFLV plant infections, is essential to efficiently control the disease. In two infested blocks of the Bordeaux vineyard, vertical distribution data showed that the highest numbers of individuals occurred at 40 to 110 cm depth, corresponding to the two layers where the highest densities of fine roots were observed. Horizontal distribution based on a 10 x 15 m grid sampling procedure revealed a significant aggregative pattern but no significant neighborhood structure of nematode densities. At a finer scale ( approximately 2 x 2 m), nematode sampling performed in a third block confirmed a significant aggregative pattern, with patches of 6 to 8 m diameter, together with a significant neighborhood structure of nematode densities, thus identifying the relevant sampling scale to describe the nematode distribution. Nematode patches correlate significantly with those of GFLV-infected grapevine plants. Finally, nematode and virus spread were shown to extend preferentially parallel to vine rows, probably due to tillage during mechanical weeding.

Abstract Objective: To test the hypothesis that disease severity in patients with cystic fibrosis (CF) is correlated with an increased risk of sleep apnea. Methods: A total of 34 CF patients underwent clinical and functional evaluation, as well as portable polysomnography, spirometry, and determination of IL-1β levels. Results: Mean apnea-hypopnea index (AHI), SpO2 on room air, and Epworth Sleepiness Scale score were 4.8 ± 2.6, 95.9 ± 1.9%, and 7.6 ± 3.8 points, respectively. Of the 34 patients, 19 were well-nourished, 6 were at nutritional risk, and 9 were malnourished. In the multivariate model to predict the AHI, the following variables remained significant: nutritional status (β = −0.386; p = 0.014); SpO2 (β = −0.453; p = 0.005), and the Epworth Sleepiness Scale score (β = 0.429; p = 0.006). The model explained 51% of the variation in the AHI. Conclusions: The major determinants of sleep apnea were nutritional status, SpO2, and daytime sleepiness. This knowledge not only provides an opportunity to define the clinical risk of having sleep apnea but also creates an avenue for the treatment and prevention of the disease. PMID:26398755

The current study examined the relationship between the Five-Factor Model personality traits and physician-confirmed peptic ulcer disease (PUD) diagnosis in a large population-based adult sample, controlling for the relevant behavioral and sociodemographic factors. Personality traits were assessed by participants themselves and by knowledgeable informants using the NEO Personality Inventory-3 (NEO PI-3). When controlling for age, sex, education, and cigarette smoking, only one of the five NEO PI-3 domain scales - higher Neuroticism - and two facet scales - lower A1: Trust and higher C1: Competence - made a small, yet significant contribution (p < 0.01) to predicting PUD in logistic regression analyses. In the light of these relatively modest associations, our findings imply that it is certain behavior (such as smoking) and sociodemographic variables (such as age, gender, and education) rather than personality traits that are associated with the diagnosis of PUD at a particular point in time. Further prospective studies with a longitudinal design and multiple assessments would be needed to fully understand if the FFM personality traits serve as risk factors for the development of PUD. © 2015 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

to explore the effects of a group health education programme on the childbearing knowledge, attitude, and behaviours among Southeast Asian immigrant women in Taiwan. a quasi-experimental design with convenience sampling was used. participants living in Kaohsiung County, Taiwan, were randomly divided by districts into either the experimental group or the control group. one hundred Southeast Asian immigrant women were recruited as research participants. Among the 100 participants, 50 were in the experimental group and 50 were in the control group. A total of 99 participants completed the entire research procedure. a structured interview was used to evaluate the effects of a group health education programme. the interview consisted of four measurements: the Demographic Inventory Scale, the Childbearing Knowledge Scale, the Childbearing Attitude Scale, and the Childbearing Planning Scale. after employing the group health education intervention, statistically significant changes from the pre-test to the post-test were found in the experimental group's scores for the Childbearing Knowledge Scale (P<0.0001), the Childbearing Attitude Scale (P<0.01), and the Childbearing Planning Scale (P<0.0001). The study's results indicated that providing education through group learning with guidance and support in childbearing health significantly improved Southeast Asian immigrant women's childbearing health knowledge, attitudes, and behaviours. an appropriate, community-based group health education programme can create awareness for childbearing health among Southeast Asian immigrant women in Taiwan and improve their childbearing attitudes and behaviours.

Knowledge architecture (KA) establishes the basic groundwork for the successful implementation of a short-term or long-term knowledge management (KM) program. An example of KA is the design of a prototype before a new vehicle is manufactured. Due to a transformation to large-scale organizations, the traditional architecture of organizations is undergoing fundamental changes. This paper explores the main strengths and weaknesses in the field of KA within large-scale organizations and provides a suitable methodology and supervising framework to overcome specific limitations. This objective was achieved by applying and updating the concepts from the Zachman information architectural framework and the information architectural methodology of enterprise architecture planning (EAP). The proposed solution may be beneficial for architects in knowledge-related areas to successfully accomplish KM within large-scale organizations. The research method is descriptive; its validity is confirmed by performing a case study and polling the opinions of KA experts. PMID:25993414

Although the impact of childhood chronic neurological diseases (CND) on patients' psychological well-being has been increasingly addressed, little attention has been given to the influence of these conditions on family members and family functioning. The purpose of the present study was to investigate the family characteristics of Greek children suffering from CND. A total of 52 parents of children with CND were studied by using the Family Environmental Scale (FES), the Family Burden Scale, the General Health Questionnaire (GHQ-28) and a questionnaire on the knowledge of their children's illness, their coping strategies and their satisfaction with our services. During the same period, 30 parents of hospitalized children for common paediatric illnesses completed the FES. In both groups social and demographic features were registered. Appropriate statistical processes were applied to compare the above-mentioned family groups and to study the differences between the families of children with epilepsy (n=37) and the families of children with other CND (n=15). Parents of children with CND discuss their problems less freely, talk less openly around home, score highly on FES subscale of Conflict and, pay more attention to ethical and religious issues and values. Furthermore, the families of children with other CND were more burdened regarding the financial state and the health status of other family members in comparison with families of children with epilepsy. In addition, families of children with epilepsy were more involved in social and recreational activities, appeared to be more knowledgeable on the availability of help in critical conditions and were more satisfied with rendered medical services, in comparison with families of children with other CND. These preliminary findings provide important information concerning the special characteristics of Greek families of children suffering from CND, which may prove especially helpful in organizing specific support services.

Background and Aims: Unintentional acetaminophen overdose remains the leading cause of acute liver failure in the United States. Patients with underlying liver disease are at higher risk of poor outcomes from acetaminophen overdose. Limited knowledge of acetaminophen may be a preventable contributor to elevated rates of overdose and thus acute liver failure. The purpose of this study is to assess knowledge of acetaminophen dosing and presence of acetaminophen in common combination products in patients with liver disease. Methods: We performed a cross-sectional study of patients with liver disease at the Pfleger Liver Institute at the University of California, Los Angeles between June 2015 and August 2016. Patients completed a demographic questionnaire and an acetaminophen knowledge survey. Additional information was obtained from the medical record. Results: Of 401 patients with liver disease, 30 (15.7%) were able to correctly identify that people without liver disease can safely take up to 4 g/day of acetaminophen. The majority of patients (79.9%-86.8%) did not know that Norco® (hydrocone/acetaminophen), Vicodin® (hydrocone/acetaminophen) and Percocet® (oxycodone/acetaminophen) contained acetaminophen. Only 45.3% of the patients knew that Tylenol® #3 contained acetaminophen. Conclusions: We conclude that patients with liver disease have critically low levels of knowledge of acetaminophen, putting them at risk both of acetaminophen overdose, as well as undermedication, and inadequate management of chronic pain. We recommend an increase in education efforts regarding acetaminophen dosage and its safety in the setting of liver disease. Increasing education for those at risk of low acetaminophen knowledge is essential to minimizing acetaminophen overdose rates and optimizing pain management.

Construction workers in South Africa are regarded as a high-risk group in the context of HIV/AIDS. HIV testing is pivotal to controlling HIV transmission and providing palliative care and AIDS-related knowledge and stigma are key issues in addressing the likelihood of testing behaviour. In exploring these issues, various studies have employed an 11-item AIDS-related knowledge scale (Kalichman and Simbayi, AIDS Care 16:572-580, 2004) and a 9-item stigma scale (Kalichman et al., AIDS Behav 9:135-143, 2005), but little evidence exists confirming the psychometric properties of these scales. Using survey data from 512 construction workers in the Western Cape, South Africa, this research examines the validity and reliability of the two scales through exploratory and confirmatory factor analysis and internal consistency tests. From confirmatory factor analysis, a revised 10-item knowledge scale was developed (χ2 /df ratio = 1.675, CFI = 0.982, RMSEA = 0.038, and Hoelter (95 %) = 393). A revised 8-item stigma scale was also developed (χ2 /df ratio = 1.929, CFI = 0.974, RMSEA = 0.045, and Hoelter (95 %) = 380). Both revised scales demonstrated good model fit and all factor loadings were significant (p < 0.01). Reliability analysis demonstrated excellent to good internal consistency, with alpha values of 0.80 and 0.74, respectively. Both revised scales also demonstrated satisfactory convergent and divergent validity. Limitations of the original survey from which the data was obtained include the failure to properly account for respondent selection of language for completion of the survey, use of ethnicity as a proxy for identifying the native language of participants, the limited geographical area from which the survey data was collected, and the limitations associated with the convenience sample. A limitation of the validation study was the lack of available data for a more robust examination of reliability beyond internal consistency, such as test-retest reliability. The revised knowledge and stigma scales offered here hold considerable promise as measures of AIDS-related knowledge and stigma among South African construction workers.
Karl Jaspers on the disease entity: Kantian ideas and Weberian ideal types.
Walker, Chris
2014-09-01
Jaspers' nosology is indebted to Immanuel Kant's theory of knowledge. He drew the distinction of form and content from the Transcendental Analytic of Kant's Critique of Pure Reason. The distinction is universal to all knowledge, including psychopathology. Individual experience is constituted by a form or category of the Understanding to give a determinate or knowable object classified into the generic type of a real disease entity. The application of form and content is limited by the boundaries of experience. Beyond this boundary are wholes whose conception requires Ideas of reason drawn from the Transcendental Dialectic. Wholes are regulated by Ideas of reason to give an object or schema of the Idea collected into ideal types of an ideal typical disease entity. Jaspers drew ideal types from Max Weber's social theory. He anticipated that, as knowledge advanced, ideal typical disease entities would become real disease entities. By 1920, this had been the destiny of general paralysis as knowledge of its neuropathology, serology and microbiology emerged. As he presented the final edition of General Psychopathology in 1946, Jaspers was anticipating the transition of schizophrenia from ideal typical to real disease entity. Almost 70 years later, with knowledge of its aetiology still unclear, schizophrenia remains marooned as an ideal typical disease entity - still awaiting that crucial advance! © The Author(s) 2014.
People with epilepsy lack knowledge about their disease.

For people with epilepsy, knowledge of their disease is an important factor in optimizing the control of their seizures. Better-informed patients can more easily participate in the treatment process, reducing disease-related anxiety and coping better with stigma. This study was developed in a Lithuanian tertiary epilepsy center to assess knowledge of disease among people with epilepsy, to estimate differences in disease knowledge between patient groups, and to evaluate how epilepsy influences patients' daily lives. We asked patients to complete a questionnaire and collected information from outpatient cards on epilepsy etiology, type of seizures, findings of diagnostic tests, and information about patients' antiepileptic drugs. Our results showed that people with epilepsy have poor knowledge about their disease: almost half of the patients did not identify the cause of their illness or their type of seizures; most did not know the results of their EEG and neuroimaging studies. Patients also lacked general knowledge about their disease and implications for lifestyle. However, cognitive deficits were not assessed in this study, and this may have affected the answers where patients were required to recall and name their drugs or the dosage of medication. Almost half of them believed that epilepsy had changed their lives significantly and reported anxiety and constant fear of seizures. Patients were also afraid to have because of the possibility they would also have epilepsy. There is clearly a great need for improved educational intervention for people with epilepsy.

Background Rubber trees (Hevea spp.) are perennial crops of Amazonian origin that have been spread over the whole tropical belt to guarantee worldwide production of natural rubber. This crop plant has found its place in many national economies of producing countries, and although its domestication by selection of suitable genotypes was very slow, it contributes a lot to the welfare of small farmers worldwide. Its development is limited by severe diseases. In South America, the main fungal disease of rubber trees is the South American leaf blight (SALB) caused by the ascomycete Microcyclus ulei. This fungus inhibits natural rubber production on a commercial scale in South and Central America. Scope The disease is still restricted to its continent of origin, but its potential to be distributed around the world rises with every transcontinental airline connection that directly links tropical regions. The need to develop control measures against the disease is an urgent task and must be carried out on an international scale. All control efforts so far taken since 1910 have ended in a miserable failure. Even the use of modern systemic fungicides and use of greatly improved application techniques have failed to prevent large losses and dieback of trees. The results of research dealing with both the disease and the pathosystem over more than 50 years are summarized and placed into perspective. Future Prospects A detailed knowledge of this host–pathogen combination requires understanding of the dynamics of Hevea leaf development, the biochemical potential for cyanide liberation, and molecular data for several types of resistance factors. Resolution of the Hevea–SALB problem may serve as a model for future host–pathogen studies of perennial plants requiring a holistic approach. PMID:17650512

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

the studies on population's knowledge and perceptions of infectious diseases contribute to develop more effective communication processes. to evaluate the knowledge and the perception of the residents in Habana Vieja municipality about tuberculosis, and to identify the ways for obtaining information about aspects of this disease. a cross-sectional study was carried out. A questionnaire was applied on a sample of 86 persons from five health areas of the municipality. A descriptive analysis was made. Odds ratios were calculated to determine association between ways for obtaining information and knowledge on the existence of the disease, symptoms and transmission forms. the respondents know about tuberculosis as a disease, its symptoms, and its presence in Cuba, but the percentages corresponding to the truly significant symptoms are low, including incorrect identifications of towel, comb and mosquitoes as transmission ways of the disease. Television, radio and friends were the most mentioned sources of information. the population from Habana Vieja municipality knows about the existence of TB. However, specific knowledge about symptoms of the disease and ways of transmissions are insufficient. Changing this situation requires the strengthening of the role of the mass media role and the development of local communication strategies suited to local characteristics.
Is susceptibility to tuberculosis acquired or inherited?
Schurr, E
2007-02-01
Tuberculosis is an ongoing major public health problem on a global scale. One of the striking features of the disease is that only an estimated 10% of immunocompetent persons infected by the causative pathogen Mycobacterium tuberculosis will develop clinical signs of disease. This well-established epidemiological observation has prompted an intense search for the factors that trigger advancement of infection to disease in the small proportion of susceptible individuals. Central to this search is the questions if tuberculosis patients are inherently susceptible to the disease or if disease development is promoted by specific environmental factors. It is known that genetic and non-genetic factors of both the bacterium and the host have impact on the host response to M. tuberculosis. Yet, little is known about the interaction of these different factors and the resulting impact on disease development. Recent work suggests that in addition to common host susceptibility genes a second group of susceptibility loci exists the action of which strongly depends on the individual's clinical and exposure history. The latter genes may have a very strong effect on promoting advancement from infection to disease only in specific epidemiological settings. These findings suggest that a more detailed knowledge of gene-environment interactions in tuberculosis is necessary to understand why a small proportion of individuals are susceptible to the disease whilst the majority of humans are naturally resistant to tuberculosis.

Diabetes mellitus (DM) is a common serious health problem. Medication adherence is a key determinant of therapeutic success in patients with diabetes mellitus. The purpose of this study was to assess medication adherence and its potential association with beliefs and diabetes - related knowledge in patients with type II DM. This study was carried out at Al-Makhfia governmental diabetes primary healthcare clinic in Nablus, Palestine. Main outcome of interest in the study was medication adherence. The Beliefs about Medicines Questionnaire (BMQ) was used to assess beliefs. Morisky Medication Adherence Scale (MMSA-8©) was used to assess medication adherence. The Michigan diabetes knowledge test (MDKT) was used to assess diabetes - related knowledge. Univariate and multivariate analysis were carried out using Statistical Package for Social Sciences (SPSS 20). Four hundred and five patients were interviewed. The mean ± SD age of the participants was 58.3 ± 10.4 (range = 28 - 90) years. More than half (53.3%) of the participants were females. Approximately 42.7% of the study sample were considered non-adherent (MMAS-8© score of < 6). Multivariate analysis showed that the following variables were significantly associated with non-adherence: disease-related knowledge, beliefs about necessity of anti-diabetic medications, concerns about adverse consequences of anti-diabetic medications and beliefs that medicines in general are essentially harmful. Diabetic patients with high knowledge score and those with strong beliefs in the necessity of their anti-diabetic medications were less likely to be non-adherent ([O.R = 0.87, 95% CI of 0.78 - 0.97] and [O.R = 0.93, 95% of 0.88 - 0.99] respectively). However, diabetic patients with high concerns about adverse consequences of anti-diabetic medications and those with high belief that all medicines are harmful were more likely to be non-adherent ([O.R = 1.09; 95% C.I of 1.04 - 1.16] and [O.R = 1.09, 95% C.I of 1.02 - 1.16] respectively). Beliefs and knowledge are important factors in understanding variations in medication adherence among diabetic patients. The BMQ can be used as a tool to identify people at higher risk of non-adherence. Improving knowledge of patients about their illness might positively influence their medication adherence.

The purpose of this study was to investigate the effect of a symptom management program on self-care of medication side effects among AIDS/HIV-positive patients. Sixty-seven patients from a sexually transmitted disease control center, a medical center, and a Catholic AIDS support group in Taipei were randomly assigned to three groups: one-on-one teaching, group teaching, and a control group. All subjects in each teaching group attended a 60- or 90-minute program on highly active antiretroviral therapy (HAART) side effect self-care education and skill training once per week for 3 weeks; subjects also underwent counseling by telephone. A medication side effect self-care knowledge questionnaire, Rosenberg's Self-Esteem Scale (RSES), and unscheduled hospital visits were used to evaluate the effectiveness of the symptom management program. The results revealed there were significant differences in mean difference of knowledge and unscheduled hospital visits between baseline and post-testing at 3 months for symptom management in the two groups. The mean difference of the self-esteem scale was not significant between the two groups. In summary, the symptom management program effectively increased the ability of AIDS/HIV-positive patients to self-care for medication side effects. We recommend that this program be applied in the clinical nursing practice.

Availability of the sequences of entire genomes shifts the scientific curiosity towards the identification of function of the genomes in large scale as in genome studies. In the near future, data produced about cellular processes at molecular level will accumulate with an accelerating rate as a result of proteomics studies. In this regard, it is essential to develop tools for storing, integrating, accessing, and analyzing this data effectively. We define an ontology for a comprehensive representation of cellular events. The ontology presented here enables integration of fragmented or incomplete pathway information and supports manipulation and incorporation of the stored data, as well as multiple levels of abstraction. Based on this ontology, we present the architecture of an integrated environment named Patika (Pathway Analysis Tool for Integration and Knowledge Acquisition). Patika is composed of a server-side, scalable, object-oriented database and client-side editors to provide an integrated, multi-user environment for visualizing and manipulating network of cellular events. This tool features automated pathway layout, functional computation support, advanced querying and a user-friendly graphical interface. We expect that Patika will be a valuable tool for rapid knowledge acquisition, microarray generated large-scale data interpretation, disease gene identification, and drug development. A prototype of Patika is available upon request from the authors.
Structure prediction of polyglutamine disease proteins: comparison of methods
2014-01-01
Background The expansion of polyglutamine (poly-Q) repeats in several unrelated proteins is associated with at least ten neurodegenerative diseases. The length of the poly-Q regions plays an important role in the progression of the diseases. The number of glutamines (Q) is inversely related to the onset age of these polyglutamine diseases, and the expansion of poly-Q repeats has been associated with protein misfolding. However, very little is known about the structural changes induced by the expansion of the repeats. Computational methods can provide an alternative to determine the structure of these poly-Q proteins, but it is important to evaluate their performance before large scale prediction work is done. Results In this paper, two popular protein structure prediction programs, I-TASSER and Rosetta, have been used to predict the structure of the N-terminal fragment of a protein associated with Huntington's disease with 17 glutamines. Results show that both programs have the ability to find the native structures, but I-TASSER performs better for the overall task. Conclusions Both I-TASSER and Rosetta can be used for structure prediction of proteins with poly-Q repeats. Knowledge of poly-Q structure may significantly contribute to development of therapeutic strategies for poly-Q diseases. PMID:25080018

Livestock diseases and other animal health events are a threat to achieving sustainable livestock industry. The knowledge of trace-back and the practice of providing feedback on diseases encountered in slaughtered animals from the abattoir to the farm can help limit the spread as well as manage potential future incidents of such diseases. We assessed the knowledge, attitudes and practices of 200 willing livestock traders on traceability in Bodija Municipal Abattoir, south-western Nigeria. The results reveal that the majority of these traders had poor knowledge (79.5 %) and practices (74.0 %) of traceability, though 89.5 % demonstrated good attitudes. While 22.9 % knew that traceability could be an effective means to control diseases, only a lower proportion (9.0 %) knew the health status of the animals being purchased. Though 29.0 % reported the diseases encountered in their animals during slaughter to the farm, only 9.5 % followed up to ensure the farmers take steps at preventing further occurrence of the reported diseases. While age (p = 0.000; 0.014) and education (p = 0.000; 0.000) were both significant for good knowledge and attitudes, frequency of condemned cases (p = 0.000) and length of years in the trade (p = 0.004) were, respectively, significant for good knowledge and attitudes with none associated with practice. These poor levels of knowledge and practices of traceability are a threat to sustainable livestock industry, food security and human health; hence, there is an urgent need to institute national feedback mechanism on slaughtered animals in order to strengthen interventions against diseases at farm levels.

There are gaps in our knowledge of the prevalence of adult atopic dermatitis (AD). To estimate the prevalence of AD in adults and by disease severity. This international, cross-sectional, web-based survey was performed in the United States, Canada, France, Germany, Italy, Spain, United Kingdom, and Japan. Adult members of online respondent panels were sent a questionnaire for AD identification and severity assessment; demographic quotas ensured population representativeness for each country. A diagnosis of AD required subjects to be positive on the modified UK Working Party/ISAAC criteria and self-report of ever having an AD diagnosis by a physician. The proportion of subjects with AD who reported being treated for their condition was determined and also used to estimate prevalence. Severity scales were Patient-Oriented SCORAD, Patient-Orientated Eczema Measure, and Patient Global Assessment. Among participants by region, the point prevalence of adult AD in the overall/treated populations was 4.9%/3.9% in the US, 3.5%/2.6% in Canada, 4.4%/3.5% in the EU, and 2.1%/1.5% in Japan. The prevalence was generally lower for males vs females, and decreased with age. Regional variability was observed within countries. Severity varied by scale and region; however, regardless of the scale or region, proportion of subjects reporting severe disease was lower than mild or moderate disease. Prevalence of adult AD ranged from 2.1% to 4.9% across countries. Severe AD represented a small proportion of the overall AD population regardless of measure or region. © 2018 EAACI and John Wiley and Sons A/S. Published by John Wiley and Sons Ltd.

Accurately translating genotype to phenotype requires accounting for the functional impact of genetic variation at many biological scales. Here we present a strategy for genotype-phenotype reasoning based on existing knowledge of cellular subsystems. These subsystems and their hierarchical organization are defined by the Gene Ontology or a complementary ontology inferred directly from previously published datasets. Guided by the ontology's hierarchical structure, we organize genotype data into an "ontotype," that is, a hierarchy of perturbations representing the effects of genetic variation at multiple cellular scales. The ontotype is then interpreted using logical rules generated by machine learning to predict phenotype. This approach substantially outperforms previous, non-hierarchical methods for translating yeast genotype to cell growth phenotype, and it accurately predicts the growth outcomes of two new screens of 2,503 double gene knockouts impacting DNA repair or nuclear lumen. Ontotypes also generalize to larger knockout combinations, setting the stage for interpreting the complex genetics of disease.

In the summer of 2015, soldiers of the 3rd Foreign Infantry Regiment and civilian scientists mounted a joint expedition on foot to reconnoiter and better define the southern frontier of French Guiana with Brazil. Three doctor-nurse pairs worked in relay to provide medical support for this unprecedented 42-day, 320-km journey through a hostile and isolated environment, a mission whose success was made possible by large-scale logistic and technical prowess. The army health department, using knowledge gained from previous large-scale missions and expeditions and from its staff's local experience, provided its technical support for personnel selection, organization of the health logistics, and field support. This article describes the difficulties encountered from a medical perspective, the diseases encountered, and the final assessments of the personnel who completed this expedition.

As primary caregiver to under-five children in Ethiopia, mothers' knowledge, perception, and management skills are important to minimize the effects of morbidity and mortality associated with diarrhoeal diseases. A community-based comparative cross-sectional study was conducted in Abramo and Megele 37 kebeles (the last administration division) in Assosa district of western Ethiopia in July 2010. Quantitative data were obtained by a structured questionnaire from 232 randomly-selected mothers having children aged less than five years regarding their knowledge, perception, and management. Qualitative data were also collected by arranging four focus group discussions involving mothers from the two communities. The prevalence of diarrhoeal diseases among under-five children was 33.2%, and the knowledge of mothers about the causes, transmission, and prevention of diarrhoea in the study area was 37.5%. The prevalence of diarrhoeal disease was higher in the settlement area whereas mothers' knowledge was better in the indigenous community; 62.9% of mothers were categorized as having good attitude on causes, transmission, and prevention of diarrhoeal disease. Community water source, water storage container, and knowledge of mothers remained a strong predictor of diarrhoeal morbidity after conducting logistic regression analysis (OR=8.4, CI 3.59-31.85; OR=2.2, CI 1.02-4.89; and OR=3.62, CI 1.23-4.71 respectively). Diarrhoeal morbidity was high in the study areas. On the contrary, knowledge and attitude of mothers, recognizing the danger sign of dehydration due to diarrhoea, and the prevention and management of childhood diarrhoeal diseases were not adequate. Information, education and communication strategy may help increase the knowledge and create positive attitude among mothers regarding the cause, prevention, and management of diarrhoea.

Diagnosing a patient's condition is one of the most important and challenging tasks in medicine. We present a study of the application of collective intelligence in medical diagnosis by applying consensus methods. We compared the accuracy obtained with this method against the diagnostics accuracy reached through the knowledge of a single expert. We used the ontological structures of ten diseases. Two knowledge bases were created by placing five diseases into each knowledge base. We conducted two experiments, one with an empty knowledge base and the other with a populated knowledge base. For both experiments, five experts added and/or eliminated signs/symptoms and diagnostic tests for each disease. After this process, the individual knowledge bases were built based on the output of the consensus methods. In order to perform the evaluation, we compared the number of items for each disease in the agreed knowledge bases against the number of items in the GS (Gold Standard). We identified that, while the number of items in each knowledge base is higher, the consensus level is lower. In all cases, the lowest level of agreement (20%) exceeded the number of signs that are in the GS. In addition, when all experts agreed, the number of items decreased. The use of collective intelligence can be used to increase the consensus of physicians. This is because, by using consensus, physicians can gather more information and knowledge than when obtaining information and knowledge from knowledge bases fed or populated from the knowledge found in the literature, and, at the same time, they can keep updated and collaborate dynamically.

To determine the effects of loneliness on illness perception in persons with a chronic disease. How an illness is perceived not only affects all dimensions of a person's life but also plays an important role in his/her coping with the complications and consequences of the disease. One of the factors that influence the illness perception is loneliness. The study is a descriptive study. The study sample included 206 individuals over the 18 years of age, conscious, having had a chronic illness at least 1 year, having no communication problems and agreeing to participate in the study after being informed about the study. Data were collected with the Personal Information Form, the Illness Perception Questionnaire and the University of California Los Angeles Loneliness Scale. The forms were administered to the participants in an unoccupied patient room, and the data were collected through face-to-face interviews. The results of the study revealed that individuals with a chronic disease perceived emotional symptoms accompanying the disease more intensely that they accepted their disease was a chronic one and that their personal control and treatment control of the disease were at a middle level. The mean score the participants obtained from the University of California Los Angeles Loneliness Scale was 38.49 ± 11.15. There was a significant negative correlation between this mean score and the mean scores obtained from the following subscales consequences, treatment control, illness perception and emotional representations. In this study, it was concluded that the participants perceived their loneliness level as moderate and that their illness perception was negatively affected as their loneliness levels increased. The knowledge of clinical nurses about perception of patients with chronic illnesses and conditions affecting that perception will enhance compliance with the illness management or treatment strategies. Clinical nurses should observe residents closely for signs of depression and loneliness and support their sense of coherence to reduce emotional and social loneliness. © 2018 John Wiley & Sons Ltd.
The Scope of Big Data in One Medicine: Unprecedented Opportunities and Challenges.
McCue, Molly E; McCoy, Annette M
2017-01-01
Advances in high-throughput molecular biology and electronic health records (EHR), coupled with increasing computer capabilities have resulted in an increased interest in the use of big data in health care. Big data require collection and analysis of data at an unprecedented scale and represents a paradigm shift in health care, offering (1) the capacity to generate new knowledge more quickly than traditional scientific approaches; (2) unbiased collection and analysis of data; and (3) a holistic understanding of biology and pathophysiology. Big data promises more personalized and precision medicine for patients with improved accuracy and earlier diagnosis, and therapy tailored to an individual's unique combination of genes, environmental risk, and precise disease phenotype. This promise comes from data collected from numerous sources, ranging from molecules to cells, to tissues, to individuals and populations-and the integration of these data into networks that improve understanding of heath and disease. Big data-driven science should play a role in propelling comparative medicine and "one medicine" (i.e., the shared physiology, pathophysiology, and disease risk factors across species) forward. Merging of data from EHR across institutions will give access to patient data on a scale previously unimaginable, allowing for precise phenotype definition and objective evaluation of risk factors and response to therapy. High-throughput molecular data will give insight into previously unexplored molecular pathophysiology and disease etiology. Investigation and integration of big data from a variety of sources will result in stronger parallels drawn at the molecular level between human and animal disease, allow for predictive modeling of infectious disease and identification of key areas of intervention, and facilitate step-changes in our understanding of disease that can make a substantial impact on animal and human health. However, the use of big data comes with significant challenges. Here we explore the scope of "big data," including its opportunities, its limitations, and what is needed capitalize on big data in one medicine.

Knowledge and Oral Health Attitudes among Parents of Children with Congenital Heart Disease.
Suvarna, Reshma; Rai, Kavita; Hegde, Amitha M
2011-01-01
Congenital heart disease (CHD) is a devastating complex of diseases resulting from defects of development. It affects more than 1 of every 100 live births. Early preventive dental care should be adjusted to the special needs of these children in their first years of life. Knowledge of parental attitudes and experiences of dental care are therefore important. Aim : This study was done to assess the knowledge and attitudes among parents of children with congenital heart disease towards oral health and dental care. Materials and methods : Parents (n = 105) of children with congenital heart disease of an age ranging from 0 to 16 years were included in the study. A questionnaire was used to assess the knowledge and oral health attitudes. Results : The parents' knowledge was fair but the oral health attitudes were not very satisfactory. The parents in this study also recognized the importance of oral health for the well-being of rest of the body. Conclusion : The results of this study indicate that parents' and children's attitudes toward oral health and dental care need to be improved.

Genetics increasingly permeate everyday medicine. When patients want to make informed decisions about genetic testing, they require genetic knowledge. This study examined the genetic knowledge and attitudes of patients with chronic diseases, and the relationship between both. In addition, patients were asked about their preferred source of genetic information. Questionnaires were mailed to participants of a nationwide representative sample of patients with chronic diseases in the Netherlands (n = 1916). The response rate was 82% (n = 1496). Perceived genetic knowledge was low, particularly among older and lower educated patients. Attitudes towards genetics were rather positive, especially among younger and higher educated patients. Some concerns were also documented, mainly about the consequences of genetic testing for employment and taking insurance. Patients who perceived to have little knowledge found it difficult to formulate an opinion about genetic testing. Higher levels of genetic knowledge were associated with a more favourable attitude towards genetics. Chronic patients prefer to receive genetic information from their GP. Chronic patients are ill prepared when they require genetic knowledge to make decisions regarding the treatment of their disease. This seems to result from a knowledge deficiency rather than from disagreement with the genetic developments. When chronic patients are in need of information about genetics or genetic testing, their general practitioner should provide this.

Multiple Sclerosis (MS) is an immune-mediated disease of the Central Nervous System with two major underlying etiopathogenic processes: inflammation and neurodegeneration. The latter determines the prognosis of this disease. MS is the main cause of non-traumatic disability in middle-aged populations. The MS-VisualPath Cohort was set up to study the neurodegenerative component of MS using advanced imaging techniques by focusing on analysis of the visual pathway in a middle-aged MS population in Barcelona, Spain. We started the recruitment of patients in the early phase of MS in 2010 and it remains permanently open. All patients undergo a complete neurological and ophthalmological examination including measurements of physical and disability (Expanded Disability Status Scale; Multiple Sclerosis Functional Composite and neuropsychological tests), disease activity (relapses) and visual function testing (visual acuity, color vision and visual field). The MS-VisualPath protocol also assesses the presence of anxiety and depressive symptoms (Hospital Anxiety and Depression Scale), general quality of life (SF-36) and visual quality of life (25-Item National Eye Institute Visual Function Questionnaire with the 10-Item Neuro-Ophthalmic Supplement). In addition, the imaging protocol includes both retinal (Optical Coherence Tomography and Wide-Field Fundus Imaging) and brain imaging (Magnetic Resonance Imaging). Finally, multifocal Visual Evoked Potentials are used to perform neurophysiological assessment of the visual pathway. The analysis of the visual pathway with advance imaging and electrophysilogical tools in parallel with clinical information will provide significant and new knowledge regarding neurodegeneration in MS and provide new clinical and imaging biomarkers to help monitor disease progression in these patients.

Men's attitudes toward public breastfeeding may influence a woman's decisions about breastfeeding and her perceived comfort with public breastfeeding. Research aim: This study aimed to evaluate factors associated with men's visual perception of images of public breastfeeding. A 95-item online survey was administered to 502 U.S. men ages 21 to 44. Respondents were presented with four images of women breastfeeding and asked to evaluate agreement with 15 adjectives describing each image. Based on factor analysis, 13 of these adjectives were combined to create the Breastfeeding Images Scale for each image. An 8-item Situational Statements Scale and the 17-item Iowa Infant Feeding Attitude Scale (IIFAS) were used to assess breastfeeding knowledge and attitudes. Multiple regression was used to evaluate the association between breastfeeding attitudes and knowledge and the Breastfeeding Images Scale. The image depicting a woman breastfeeding privately at home had the highest mean score of 71.95, 95% confidence interval (CI) [70.69, 73.22], on the Breastfeeding Images Scale, compared with 61.93, 95% CI [60.51, 63.36], for the image of a woman breastfeeding in a public setting. The overall mean scale score for the IIFAS was 56.99, 95% CI [56.27, 57.70], and for the Situational Statements Scale was 28.80, 95% CI [27.92, 29.69]. For all images, increasing breastfeeding knowledge and attitudes measured by the IIFAS and the Situational Statements Scale were associated with a more positive perception of the image. Images of public breastfeeding are viewed less favorably by men in the sample than are images of private breastfeeding. Knowledge and attitudes toward breastfeeding are positively associated with perception of breastfeeding images.

Cosmetologists frequently develop occupational skin disease related to workplace exposures. The purpose of this study was to evaluate an educational intervention to increase cosmetology students' occupational skin disease knowledge and use of preventive practices. A quasi-experimental design was used to evaluate students' knowledge, behaviors, intentions, expectancies, and expectations. A 20-minute verbal presentation and printed two-page educational handout were provided for participants. Statistically significant increases in knowledge, frequency of glove use, and frequency of moisturizer use were found, but the frequency of handwashing did not increase. In addition, the Behavioral Strategies subscale, the Intention subscale, and the Expectancies subscale showed statistically significant improvements. The results of this study suggest an educational intervention can increase cosmetology students' knowledge of occupational skin diseases and their use of preventive strategies.

Debating Sex: Education Films and Sexual Morality for the Young in Post-War Germany, 1945-1955.
Winkler, Anita
2015-01-01
After 1945 rapidly climbing figures of venereal disease infections menaced the health of the war-ridden German population. Physicians sought to gain control over this epidemic and initiated large-scale sex education campaigns to inform people about identification, causes and treatment of VD and advised them on appropriate moral sexual behaviour as a prophylactic measure. Film played a crucial role in these campaigns. As mass medium it was believed film could reach out to large parts of society and quickly disseminate sexual knowledge and moral codes of conduct amongst the population. This essay discusses the transition of the initial central role of sex education films in the fight against venereal disease in the immediate post-war years towards a more critical stance as to the effects of cinematographic education of the young in an East and West German context.

The packaging of genetic material into chromatin and chromosomes has been recognized for more than a century, thanks to microscopy and biochemical approaches. This was followed by the progressive realization that chromatin organization is critical for genome functions such as transcription and DNA replication and repair. The recent discovery that chromosomes are partitioned at the submegabase scale into topologically associating domains (TADs) has implications for our understanding of gene regulation during developmental processes such as X-chromosome inactivation, as well as for evolution and for the search for disease-associated loci. Here we discuss our current knowledge about this recently recognized level of mammalian chromosome organization, with a special emphasis on the potential role of TADs as a structural basis for the function and evolution of mammalian regulatory landscapes. © 2017 Galupa and Heard; Published by Cold Spring Harbor Laboratory Press.

Toxoplasmosis, caused by Toxoplasma gondii, is one of the most prevalent parasitic diseases; it is estimated to affect a third of the world's human population. Many studies showed that latent toxoplasmosis may cause in some patients significant adverse effects including schizophrenia and bipolar disorders. In addition, two recent studies highlighted a positive correlation between the prevalence of brain tumors and that of T. gondii at national and international scale. These studies are correlative, thus they do not demonstrate a causal link between T. gondii and brain tumors. Yet, they call for further research that could shed light on the possible mechanisms underlying this association.
The changing face of dentistry: nanotechnology

The human body comprises molecules; hence, the availability of molecular nanotechnology will permit dramatic progress to address medical problems and will use molecular knowledge to maintain and improve human health at the molecular scale. Nanomedicine could develop devices that are able to work inside the human body in order to identify the early presence of a disease, and to identify and quantify toxic molecules and tumor cells, for example. Nanodentistry will make possible the maintenance of comprehensive oral health by employing nanomaterials, including tissue engineering and, ultimately, dental nanorobots. This review is an attempt to highlight the possible applications of nanotechnology and the use of nanomaterials in dentistry. PMID:22131826
Mildew-Omics: How Global Analyses Aid the Understanding of Life and Evolution of Powdery Mildews.
Bindschedler, Laurence V; Panstruga, Ralph; Spanu, Pietro D
2016-01-01
The common powdery mildew plant diseases are caused by ascomycete fungi of the order Erysiphales. Their characteristic life style as obligate biotrophs renders functional analyses in these species challenging, mainly because of experimental constraints to genetic manipulation. Global large-scale ("-omics") approaches are thus particularly valuable and insightful for the characterisation of the life and evolution of powdery mildews. Here we review the knowledge obtained so far from genomic, transcriptomic and proteomic studies in these fungi. We consider current limitations and challenges regarding these surveys and provide an outlook on desired future investigations on the basis of the various -omics technologies.

Abstract Background and Aims: Unintentional acetaminophen overdose remains the leading cause of acute liver failure in the United States. Patients with underlying liver disease are at higher risk of poor outcomes from acetaminophen overdose. Limited knowledge of acetaminophen may be a preventable contributor to elevated rates of overdose and thus acute liver failure. The purpose of this study is to assess knowledge of acetaminophen dosing and presence of acetaminophen in common combination products in patients with liver disease. Methods: We performed a cross-sectional study of patients with liver disease at the Pfleger Liver Institute at the University of California, Los Angeles between June 2015 and August 2016. Patients completed a demographic questionnaire and an acetaminophen knowledge survey. Additional information was obtained from the medical record. Results: Of 401 patients with liver disease, 30 (15.7%) were able to correctly identify that people without liver disease can safely take up to 4 g/day of acetaminophen. The majority of patients (79.9%–86.8%) did not know that Norco® (hydrocone/acetaminophen), Vicodin® (hydrocone/acetaminophen) and Percocet® (oxycodone/acetaminophen) contained acetaminophen. Only 45.3% of the patients knew that Tylenol® #3 contained acetaminophen. Conclusions: We conclude that patients with liver disease have critically low levels of knowledge of acetaminophen, putting them at risk both of acetaminophen overdose, as well as undermedication, and inadequate management of chronic pain. We recommend an increase in education efforts regarding acetaminophen dosage and its safety in the setting of liver disease. Increasing education for those at risk of low acetaminophen knowledge is essential to minimizing acetaminophen overdose rates and optimizing pain management. PMID:28097095

The objective of this study was to examine the perceived importance, knowledge and confidence in nutritional management in a sample of Australian medical students undertaking a 4-year postgraduate medical degree. In 2015, students in years 1-4 were anonymously surveyed to assess students' perceived importance of nutrition, and knowledge and confidence in nutritional management. A total of 131 first and second year (preclinical/yr 1-2) medical students (46% response rate) and 66 third and fourth year (clinical/yr 3-4) students (24% response rate) completed the questionnaire. Most preclinical students agreed that medical graduates should understand nutritional issues in managing cardiovascular disease (99%), type 2 diabetes (93%), coeliac disease (95%), and renal impairment (97%). However, students were limited in their confidence to demonstrate this knowledge (range of confidence: 26%-41%) for individual medical conditions. This improved for students in the clinical context of years 3 and 4, although it was still not optimal (range 26%-81%). Few year 3 and 4 students reported confidence in knowledge related to medicolegal issues, respiratory disease, nutritional guidelines and nutrition assessment (all <40%). However the majority (>80%) reported confidence in the dietary management of type 2 diabetes, cardiovascular disease and coeliac disease and >60% indicated they would refer onto nutrition professionals. This cohort of postgraduate medical students recognize the importance of nutrition in disease. The number of students reporting increased confidence in nutritional management of a few select diseases where dietary management is one of the cornerstones of treatment (e.g. type 2 diabetes) rises throughout the course. However, students reported lower levels of knowledge in diseases where diet is secondary to other treatments and preventative strategies (e.g. respiratory disease). Filling the gap by integrating the nutritional management into the range of common chronic diseases during training has the potential to positively impact on patient health outcomes.

Veterinary Herbal Medicine (VHM) is a comprehensive, current, and informative discipline on the utilization of herbs in veterinary practice. Driven by chemistry but progressively directed by pharmacology and the clinical sciences, drug research has contributed more to address the needs for innovative veterinary medicine for curing animal diseases. However, research into veterinary medicine of vegetal origin in the pharmaceutical industry has reduced, owing to questions such as the short of compatibility of traditional natural-product extract libraries with high-throughput screening. Here, we present a cross-species chemogenomic screening platform to dissect the genetic basis of multifactorial diseases and to determine the most suitable points of attack for future veterinary medicines, thereby increasing the number of treatment options. First, based on critically examined pharmacology and text mining, we build a cross-species drug-likeness evaluation approach to screen the lead compounds in veterinary medicines. Second, a specific cross-species target prediction model is developed to infer drug-target connections, with the purpose of understanding how drugs work on the specific targets. Third, we focus on exploring the multiple targets interference effects of veterinary medicines by heterogeneous network convergence and modularization analysis. Finally, we manually integrate a disease pathway to test whether the cross-species chemogenomic platform could uncover the active mechanism of veterinary medicine, which is exemplified by a specific network module. We believe the proposed cross-species chemogenomic platform allows for the systematization of current and traditional knowledge of veterinary medicine and, importantly, for the application of this emerging body of knowledge to the development of new drugs for animal diseases.

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
[New knowledge of the pathogenesis of Crohn's disease].

Crohns disease is a complex chronic inflammatory disease of the gastrointestinal tract with multifactorial pathogenesis. Over the recent years, there has been rather a sharp increase in the incidence of Crohn's disease and, even though this disease had been known for some time, the cause remains unknown. Studies exploring genetic basis of Crohn's disease have provided new knowledge of the pathogenesis of this disease, suggesting that this may be associated with a failure of mechanisms behind symbiosis of gut microflora and intestinal mucosal immune system. Crohn's disease seems to be caused by inadequate immune response to intestinal flora in genetically predisposed individuals. Crohn's disease has been linked to a number of genes. Many of them are related to the modulation of non-specific immune response, defects of which are considered to be key in Crohn's disease pathogenesis. The aim of this review paper is to summarize the new knowledge on the pathogenesis of Crohn's disease at the level of polymorphisms of the NOD2, ATG16L1 genes and the IL23-Th17-lymfocytes signalling pathway genes and to consider further research directions in this disease.

Effective treatments are available for patients with inflammatory bowel disease (IBD); however, suboptimal outcomes occur and are often linked to patients' limited disease knowledge. The aim of this analysis was to determine if delivery of educational messages through a telemedicine system improves IBD knowledge. TELEmedicine for Patients with IBD (TELE-IBD) was a randomized controlled trial with visits at baseline, 6 months, and 12 months; patient knowledge was a secondary aim of the study. Patients were randomized to receive TELE-IBD every other week (EOW), weekly (TELE-IBD W), or standard of care. Knowledge was assessed at each visit with the Crohn's and Colitis Knowledge (CCKNOW) survey. The primary outcome was change in CCKNOW score over 1 year compared between the TELE-IBD and control groups. This analysis included 219 participants. Participants in the TELE-IBD arms had a greater improvement in CCKNOW score compared with standard care (TELE-IBD EOW +2.4 vs standard care +1.8, P = 0.03; TELE-IBD W +2.0 vs standard care +1.8, P = 0.35). Participants with lower baseline CCKNOW scores had a greater change in their score over time (P < 0.01). However, after adjusting for race, site, and baseline knowledge, there was no difference in CCKNOW score change between the control and telemedicine arms. Telemedicine improves IBD-specific knowledge through text messaging, although the improvement is not additive with greater frequency of text messages. However, after adjustment for confounding variables, telemedicine is not superior to education given through standard visits at referral centers. Further research is needed to determine if revised systems with different modes of delivery and/or frequency of messages improve disease knowledge.

Biomedical ontologies offer the capability to structure and represent domain-specific knowledge semantically. Disease-specific ontologies can facilitate knowledge exchange across multiple disciplines, and ontology-driven mining approaches can generate great value for modeling disease mechanisms. However, in the case of neurodegenerative diseases such as Alzheimer's disease, there is a lack of formal representation of the relevant knowledge domain. Alzheimer's disease ontology (ADO) is constructed in accordance to the ontology building life cycle. The Protégé OWL editor was used as a tool for building ADO in Ontology Web Language format. ADO was developed with the purpose of containing information relevant to four main biological views-preclinical, clinical, etiological, and molecular/cellular mechanisms-and was enriched by adding synonyms and references. Validation of the lexicalized ontology by means of named entity recognition-based methods showed a satisfactory performance (F score = 72%). In addition to structural and functional evaluation, a clinical expert in the field performed a manual evaluation and curation of ADO. Through integration of ADO into an information retrieval environment, we show that the ontology supports semantic search in scientific text. The usefulness of ADO is authenticated by dedicated use case scenarios. Development of ADO as an open ADO is a first attempt to organize information related to Alzheimer's disease in a formalized, structured manner. We demonstrate that ADO is able to capture both established and scattered knowledge existing in scientific text. Copyright © 2014 The Alzheimer's Association. Published by Elsevier Inc.

Community health workers (CHW) can screen for cardiovascular disease risk as well as health professionals using a noninvasive screening tool. However, this demonstrated success does not guarantee effective scaling of the intervention to a population level. This study sought to report lessons learned from supervisors' experiences monitoring CHW and perceptions of other stakeholders regarding features for successful scaling of interventions that incorporate task-sharing with CHW. We conducted a qualitative analysis of in-depth interviews to explore stakeholder perceptions. Data was collected through interviews of 36 supervisors and administrators at nongovernmental organizations contracted to deliver and manage primary care services using CHW, directors, and staff at the government health care clinics, and officials from the departments of health responsible for the implementation of health policy. CHW are recognized for their value in offsetting severe human resource shortages and for their expert community knowledge. There is a lack of clear definitions for roles, expectations, and career paths for CHW. Formal evaluation and supervisory systems are highly desirable but nonexistent or poorly implemented, creating a critical deficit for effective implementation of programs using task-sharing. There is acknowledgment of environmental challenges (e.g., safety) and systemic challenges (e.g., respect from trained health professionals) that hamper the effectiveness of CHW. The government-community relationships presumed to form the basis of redesigned health care services have to be supported more explicitly and consistently on both sides in order to increase the acceptability of CHW and their effectiveness. The criteria critical for successful scaling of CHW-led screening are consistent with evidence for scaling-up communicable disease programs. Policy makers have to commit appropriate levels of resources and political will to ensure successful scaling of this intervention. Copyright © 2015 World Heart Federation (Geneva).

Workers' knowledge and beliefs about cardiometabolic health risk.
Damman, Olga C; van der Beek, Allard J; Timmermans, Danielle R M

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

Kidney disease is an important cause of morbidity and mortality in dogs. Knowledge about the epidemiology of kidney disease in the dog population is valuable and large-scale epidemiological studies are needed. The aim of the present study was to use insurance data to estimate kidney-related morbidity and mortality in the Swedish dog population. Insurance company data from insured dogs during the years 1995-2006 were studied retrospectively. Incidence and mortality were calculated for the whole group of dogs as well as divided by sex and breed. The total number of veterinary care insured dogs was 665,245. The total incidence of kidney disease in this group of dogs was 15.8 (15.3-16.2) cases/10,000 dog-years at risk. The number of dogs in the life insurance was 548,346 and in this group the total kidney-related mortality was 9.7 (9.3-10.2) deaths/10,000 dog-years at risk. The three breeds with the highest incidence of kidney disease were the Bernese mountain dog, miniature schnauzer and boxer. The three breeds with the highest mortality caused by kidney disease were the Bernese mountain dog, Shetland sheepdog and flat-coated retriever. In conclusion, the epidemiological information provided in this study concerning kidney disease in dogs can provide valuable information for future research. British Veterinary Association.
Inborn errors of metabolism and the human interactome: a systems medicine approach.
Woidy, Mathias; Muntau, Ania C; Gersting, Søren W
2018-02-05
The group of inborn errors of metabolism (IEM) displays a marked heterogeneity and IEM can affect virtually all functions and organs of the human organism; however, IEM share that their associated proteins function in metabolism. Most proteins carry out cellular functions by interacting with other proteins, and thus are organized in biological networks. Therefore, diseases are rarely the consequence of single gene mutations but of the perturbations caused in the related cellular network. Systematic approaches that integrate multi-omics and database information into biological networks have successfully expanded our knowledge of complex disorders but network-based strategies have been rarely applied to study IEM. We analyzed IEM on a proteome scale and found that IEM-associated proteins are organized as a network of linked modules within the human interactome of protein interactions, the IEM interactome. Certain IEM disease groups formed self-contained disease modules, which were highly interlinked. On the other hand, we observed disease modules consisting of proteins from many different disease groups in the IEM interactome. Moreover, we explored the overlap between IEM and non-IEM disease genes and applied network medicine approaches to investigate shared biological pathways, clinical signs and symptoms, and links to drug targets. The provided resources may help to elucidate the molecular mechanisms underlying new IEM, to uncover the significance of disease-associated mutations, to identify new biomarkers, and to develop novel therapeutic strategies.

To develop a system for checking indication and contraindication of medicines in prescription order entry system, a master table consisting of the disease names corresponding to the medicines adopted in a hospital is needed. The creation of this table requires a considerable manpower. We developed a Web-based system for constructing a medicine/disease thesaurus and a knowledge base. By authority management of users, this system enables many specialists to create the thesaurus collaboratively without confusion. It supports the creation of a knowledge base using concept names by referring to the thesaurus, which is automatically converted to the check master table. When a disease name or medicine name was added to the thesaurus, the check table was automatically updated. We constructed a thesaurus and a knowledge base in the field of circulatory system disease. The knowledge base linked with the thesaurus proved to be efficient for making the check master table for indication/contraindication of medicines.

Prenatal knowledge and informational priorities of pregnant adolescents.
Smith, P B; Levenson, P M; Morrow, J R
1985-01-01
One hundred and forty-six indigent pregnant adolescents (12 to 18 years of age) were asked to complete a questionnaire concerning their prenatal care priorities (Scale I) and their knowledge of correct perinatal behaviors (Scale II). On Scale I, over 75% of teens considered parenting skills, infant care, and diet extremely important. On Scale II correctly answered items focused on the need to avoid substance abuse and smoking during pregnancy, visit the doctor, and eat balanced meals. The mean number of correct answers, however, was only 11.8 out of a total possible scale of 18 items. Less than 50% correctly answered statements about the effects of weight gain and other health behaviors on risk for high blood pressure and toxemia, safety of laxatives during pregnancy, possibility of becoming pregnant again before resuming menstruation, and the safety of various physical activities. Performance on both knowledge and health priority scales showed correct health information was limited to basic concrete facts. Abstract and technical aspects of health care did not appear to be easily assimilated.

High scientific literacy is widely considered a public good. Methods of assessing public scientific knowledge or literacy are equally important. In an effort to measure lay scientific literacy in the United States, the National Science Foundation (NSF) science literacy scale has been a part of the last three waves of the General Social Survey. However, there has been debate over the validity of some survey items as indicators of science knowledge. While many researchers treat the NSF science scale as measuring a single dimension, previous work (Bann and Schwerin, 2004; Miller, 1998, 2004) suggests a bidimensional structure. This paper hypothesizes and tests a new measurement model for the NSF science knowledge scale and finds that two items about evolution and the big bang are more measures of a religious belief dimension termed "Young Earth Worldview" than they are measures of scientific knowledge. Results are replicated in seven samples. © The Author(s) 2013.
Antimicrobial knowledge and confidence amongst final year medical students in Australia
Weier, Naomi; Thursky, Karin
2017-01-01
Introduction Inappropriate use of antimicrobials is one of the major modifiable contributors to antimicrobial resistance. There is currently no validated survey tool available to assess knowledge and confidence of medical students in infectious diseases (ID) compared to other diseases states, and little is known about this topic. Materials and methods A cross-sectional survey of final year medical students attending universities around Australia was conducted between August and September, 2015. A survey unique from other published studies was developed to survey satisfaction in education, confidence and knowledge in ID, and how this compared to these factors in cardiovascular diseases. Results Reliability and validity was demonstrated in the survey tool used. Students were more likely to rate university education as sufficient for cardiovascular diseases (91.3%) compared to ID (72.5%), and were more confident in their knowledge of cardiovascular diseases compared to ID (74.38% vs. 53.76%). Students tended to answer more cardiovascular disease related clinical questions correctly (mean score 78%), compared to questions on antimicrobial use (mean score 45%). Conclusions Poor knowledge and confidence amongst final year medical students in Australia were observed in ID. Antimicrobial stewardship agenda should include the provision of additional training in antimicrobial prescribing to the future medical workforce. PMID:28771549

Many challenges to adaptation decision-making and action have been identified across peer-reviewed and gray literature. These challenges have primarily focused on the use of climate knowledge for adaptation decision-making, the process of adaptation decision-making, and the needs of the decision-maker. Studies on climate change knowledge systems often discuss the imperative role of climate knowledge producers in adaptation decision-making processes and stress the need for producers to engage in knowledge co-production activities and to more effectively meet decision-maker needs. While the influence of climate knowledge producers on the co-production of science for adaptation decision-making is well-recognized, hardly any research has taken a direct approach to analyzing the challenges that climate knowledge producers face when undertaking science co-production. Those challenges can influence the process of knowledge production and may hinder the creation, utilization, and dissemination of actionable knowledge for adaptation decision-making. This study involves semi-structured interviews, focus groups, and participant observations to analyze, identify, and contextualize the challenges that climate knowledge producers in Sweden face as they endeavor to create effective climate knowledge systems for multiple contexts, scales, and levels across the European Union. Preliminary findings identify complex challenges related to education, training, and support; motivation, willingness, and culture; varying levels of prioritization; professional roles and responsibilities; the type and amount of resources available; and professional incentive structures. These challenges exist at varying scales and levels across individuals, organizations, networks, institutions, and disciplines. This study suggests that the creation of actionable knowledge for adaptation decision-making is not supported across scales and levels in the climate knowledge production landscape. Additionally, enabling the production of actionable knowledge for adaptation decision-making requires multi-level effort beyond the individual level.

The research teams undertook a case study design using a common analytical framework to investigate three provincial (Prince Edward Island, New Brunswick and Manitoba) knowledge exchange systems. These three knowledge exchange systems seek to generate and enhance the use of evidence in policy development, program planning and evaluation to improve youth health and chronic disease prevention. We applied a case study design to explore the lessons learned, that is, key conditions or processes contributing to the development of knowledge exchange capacity, using a multi-data collection method to gain an in-depth understanding. Data management, synthesis and analysis activities were concurrent, iterative and ongoing. The lessons learned were organized into seven "clusters." Key findings demonstrated that knowledge exchange is a complex process requiring champions, collaborative partnerships, regional readiness and the adaptation of knowledge exchange to diverse stakeholders. Overall, knowledge exchange systems can increase the capacity to exchange and use evidence by moving beyond collecting and reporting data. Areas of influence included development of new partnerships, expanded knowledge-sharing activities, and refinement of policy and practice approaches related to youth health and chronic disease prevention.

Knowledge translation (KT) and related terms have variously been defined as process and as products. In this paper we contribute to debates on effective KT, specifically knowledge brokering, by describing an adaptation of Program Science that aligns with the real-world of public health activities. We describe an adaptation of the Program Science framework to our knowledge translation and brokering planning and projects at the National Collaborating Centre for Infectious Diseases. The systematic approach allows for layering of knowledge year to year and translating knowledge from one infectious disease content area to another. Using a recent forum on syphilis outbreaks as an example, we also demonstrate the value of using Program Science to shape the design and delivery of the knowledge brokering event. The use of scientific knowledge to improve public health program design, implementation and evaluation forms the basis for the program science framework. Providing the right public health information to the right audience at the right time can foster long-term outcomes of networks and new partnerships which can potentially improve delivery of public health services.
Case-based tutoring from a medical knowledge base.
Chin, H L; Cooper, G F

The past decade has seen the emergence of programs that make use of large knowledge bases to assist physicians in diagnosis within the general field of internal medicine. One such program, Internist-I, contains knowledge about over 600 diseases, covering a significant proportion of internal medicine. This paper describes the process of converting a subset of this knowledge base--in the area of cardiovascular diseases--into a probabilistic format, and the use of this resulting knowledge base to teach medical diagnostic knowledge. The system (called KBSimulator--for Knowledge-Based patient Simulator) generates simulated patient cases and uses these cases as a focal point from which to teach medical knowledge. This project demonstrates the feasibility of building an intelligent, flexible instructional system that uses a knowledge base constructed primarily for medical diagnosis.

Introduction The use of generic medicines is a cost-effective policy, often dictated by fiscal restraints. To our knowledge, no fully validated tool exploring the students’ knowledge and attitudes towards generic medicines exists. The aim of our study was to develop and validate a questionnaire exploring the knowledge and attitudes of M.Sc. in Health Care Management students and recent alumni’s towards generic drugs in Greece. Materials and methods The development of the questionnaire was a result of literature review and pilot-testing of its preliminary versions to researchers and students. The final version of the questionnaire contains 18 items measuring the respondents’ knowledge and attitude towards generic medicines on a 5-point Likert scale. Given the ordinal nature of the data, ordinal alpha and polychoric correlations were computed. The sample was randomly split into two halves. Exploratory factor analysis, performed in the first sample, was used for the creation of multi-item scales. Confirmatory factor analysis and Generalized Linear Latent and Mixed Model analysis (GLLAMM) with the use of the rating scale model were used in the second sample to assess goodness of fit. An assessment of internal consistency reliability, test-retest reliability, and construct validity was also performed. Results Among 1402 persons contacted, 986 persons completed our questionnaire (response rate = 70.3%). Overall Cronbach’s alpha was 0.871. The conjoint use of exploratory and confirmatory factor analysis resulted in a six-scale model, which seemed to fit the data well. Five of the six scales, namely trust, drug quality, state audit, fiscal impact and drug substitution were found to be valid and reliable, while the knowledge scale suffered only from low inter-scale correlations and a ceiling effect. However, the subsequent confirmatory factor and GLLAMM analyses indicated a good fit of the model to the data. Conclusions The ATTOGEN instrument proved to be a reliable and valid tool, suitable for assessing students’ knowledge and attitudes towards generic medicines. PMID:29186163

Alzheimer disease is an increasingly common condition in older people. Knowledge of life expectancy after the diagnosis of Alzheimer disease and of associations of patient characteristics with survival may help planning for future care. To investigate the course of Alzheimer disease after initial diagnosis and examine associations hypothesized to correlate with survival among community-dwelling patients with Alzheimer disease. Prospective observational study. An Alzheimer disease patient registry from a base population of 23 000 persons age 60 years and older in the Group Health Cooperative, Seattle, Washington. 521 newly recognized persons with Alzheimer disease enrolled from 1987 to 1996 in an Alzheimer disease patient registry. Baseline measurements included patient demographic features, Mini-Mental State Examination score, Blessed Dementia Rating Scale score, duration since reported onset of symptoms, associated symptoms, comorbid conditions, and selected signs. Survival was the outcome of interest. The median survival from initial diagnosis was 4.2 years for men and 5.7 years for women with Alzheimer disease. Men had poorer survival across all age groups compared with females. Survival was decreased in all age groups compared with the life expectancy of the U.S. population. Predictors of mortality based on proportional hazards models included a baseline Mini-Mental State Examination score of 17 or less, baseline Blessed Dementia Rating Scale score of 5.0 or greater, presence of frontal lobe release signs, presence of extrapyramidal signs, gait disturbance, history of falls, congestive heart failure, ischemic heart disease, and diabetes at baseline. The base population, although typical of the surrounding Seattle community, may not be representative of other, more diverse populations. In this sample of community-dwelling elderly persons who received a diagnosis of Alzheimer disease, survival duration was shorter than predicted on the basis of U.S. population data, especially for persons with onset at relatively younger ages. Features significantly associated with reduced survival at diagnosis were increased severity of cognitive impairment, decreased functional level, history of falls, physical examination findings of frontal release signs, and abnormal gait. The variables most strongly associated with survival were measures of disease severity at the time of diagnosis. These results should be useful to patients and families experiencing Alzheimer disease, other caregivers, clinicians, and policymakers when planning for future care needs.

This study was designed to analyze the knowledge, misconceptions, and lacks about Attention Deficit Hyperactivity Disorder (ADHD) in a sample of 193 teachers, as a replication of the study carried by Sciutto, Terjesen and Bender in 2000. Teachers completed the Knowledge of Attention Deficit Hyperactivity Disorder (KADDS) (Spanish version), adapted by the authors of this research, to measure knowledge of ADHD in three content areas: general knowledge, symptoms/diagnosis, and treatment. Results indicated an average of correct responses of 31.67, 63.88 and 40.46% in general knowledge, symptoms/diagnosis and treatment, respectively. Teachers displayed significantly more knowledge in the Symptoms/Diagnosis scale than in the other scales. Their knowledge correlated positively with: years of experience with hyperactive children, number of hyperactive pupils in their classrooms, and level of perceived self-efficacy. These findings are consistent with those obtained by Sciutto and colleagues.

Variability in severity and progression of Parkinson’s disease symptoms makes it challenging to design therapy interventions that provide maximal benefit. Previous studies showed that forced cycling, at greater pedaling rates, results in greater improvements in motor function than voluntary cycling. The precise mechanism for differences in function following exercise is unknown. We examined the complexity of biomechanical and physiological features of forced and voluntary cycling and correlated these features to improvements in motor function as measured by the Unified Parkinson’s Disease Rating Scale (UPDRS). Heart rate, cadence, and power were analyzed using entropy signal processing techniques. Pattern variability in heart rate and power were greater in the voluntary group when compared to forced group. In contrast, variability in cadence was higher during forced cycling. UPDRS Motor III scores predicted from the pattern variability data were highly correlated to measured scores in the forced group. This study shows how time series analysis methods of biomechanical and physiological parameters of exercise can be used to predict improvements in motor function. This knowledge will be important in the development of optimal exercise-based rehabilitation programs for Parkinson’s disease. PMID:23144045

Cardiovascular diseases and diabetes are the biggest causes of death globally. Therefore, prevention of these diseases is a focus of pharmaceuticals and functional food manufacturers. This review summarizes recent research trends and scientific knowledge in seaweed protein-derived peptides with particular emphasis on production, isolation and potential health impacts in prevention of hypertension, diabetes and oxidative stress. The current status and future prospects of bioactive peptides are also discussed. Bioactive peptides have strong potential for use in therapeutic drug and functional food formulation in health management strategy, especially cardiovascular disease and diabetes. Seaweeds can be used as sustainable protein sources in the production of these peptide-based drugs and functional foods for preventing such diseases. Many studies have reported that peptides showing angiotensin converting enzyme inhibition, antihypertensive, antioxidative and antidiabetics activities, have been successfully isolated from seaweed. However, further research is needed in large-scale production of these peptides, efficient isolation methods, interactions with functional foods and other pharmaceuticals, and their ease to digestion in in vivo studies and safety to validate the health benefits of these peptides. © 2017 Institute of Food Technologists®.

Traumatic brain injury (TBI) has been called “the most complicated disease of the most complex organ of the body” and is an increasingly high-profile public health issue. Many patients report long-term impairments following even “mild” injuries, but reliable criteria for diagnosis and prognosis are lacking. Every clinical trial for TBI treatment to date has failed to demonstrate reliable and safe improvement in outcomes, and the existing body of literature is insufficient to support the creation of a new classification system. Concussion, or mild TBI, is a highly heterogeneous phenomenon, and numerous factors interact dynamically to influence an individual’s recovery trajectory. Many of the obstacles faced in research and clinical practice related to TBI and concussion, including observed heterogeneity, arguably stem from the complexity of the condition itself. To improve understanding of this complexity, we review the current state of research through the lens provided by the interdisciplinary field of systems science, which has been increasingly applied to biomedical issues. The review was conducted iteratively, through multiple phases of literature review, expert interviews, and systems diagramming and represents the first phase in an effort to develop systems models of concussion. The primary focus of this work was to examine concepts and ways of thinking about concussion that currently impede research design and block advancements in care of TBI. Results are presented in the form of a multi-scale conceptual framework intended to synthesize knowledge across disciplines, improve research design, and provide a broader, multi-scale model for understanding concussion pathophysiology, classification, and treatment.

Knowledge of the within-host genetic diversity of a pathogen often has broad implications for disease management. Cryptosporidium protozoan parasites are among the most common causative agents of infectious diarrhoea. Current limitations of in vitro culture impose the use of uncultured isolates obtained directly from the hosts as operational units of Cryptosporidium genotyping. The validity of this practice is centred on the assumption of genetic homogeneity of the parasite within the host, and genetic studies often take little account of the within-host genetic diversity of Cryptosporidium. Yet, theory and experimental evidence contemplate genetic diversity of Cryptosporidium at the within-host scale, but this diversity is not easily identified by genotyping methods ill-suited for the resolution of DNA mixtures. We performed a systematic bibliographical search of the occurrence of within-host genetic diversity of Cryptosporidium parasites in epidemiological samples, between 2005 and 2015. Our results indicate that genetic diversity at the within-host scale, in the form of mixed species or intra-species diversity, has been identified in a large number (n=55) of epidemiological surveys of cryptosporidiosis in variable proportions, but has often been treated as a secondary finding and not analysed. As in malaria, there are indications that the scale of this diversity varies between geographical regions, perhaps depending on the prevailing transmission pathways. These results provide a significant knowledge base from which to draw alternative population genetic structure models, some of which are discussed in this paper.

Understanding the genetic basis of complex diseases is challenging. Prior work shows that disease-related proteins do not typically function in isolation. Rather, they often interact with each other to form a network module that underlies dysfunctional mechanistic pathways. Identifying such disease modules will provide insights into a systems-level understanding of molecular mechanisms of diseases. Owing to the incompleteness of our knowledge of disease proteins and limited information on the biological mediators of pathobiological processes, the key proteins (seed proteins) for many diseases appear scattered over the human protein-protein interactome and form a few small branches, rather than coherent network modules. In this paper, we develop a network-based algorithm, called the Seed Connector algorithm (SCA), to pinpoint disease modules by adding as few additional linking proteins (seed connectors) to the seed protein pool as possible. Such seed connectors are hidden disease module elements that are critical for interpreting the functional context of disease proteins. The SCA aims to connect seed disease proteins so that disease mechanisms and pathways can be decoded based on predicted coherent network modules. We validate the algorithm using a large corpus of 70 complex diseases and binding targets of over 200 drugs, and demonstrate the biological relevance of the seed connectors. Lastly, as a specific proof of concept, we apply the SCA to a set of seed proteins for coronary artery disease derived from a meta-analysis of large-scale genome-wide association studies and obtain a coronary artery disease module enriched with important disease-related signaling pathways and drug targets not previously recognized.

The American College of Cardiology (ACC), in collaboration with the National Board of Medical Examiners (NBME), developed the first standardized in-training examination (ITE) for cardiovascular disease fellows-in-training (FITs). In addition to testing knowledge, this examination uses the newly developed ACC Curricular Milestones to provide specific, competency-based feedback to program directors and FITs. The ACC ITE has been administered more than 5,000 times since 2011. This analysis sought to report the initial experience with the ITE, including feasibility and reliability of test development and implementation, as well as the ability of this process to provide useful feedback in key content areas. The annual ACC ITE has been available to cardiovascular disease fellowship programs in the United States since 2011. Questions for this Web-based, secure, multiple-choice examination were developed by a group of cardiovascular disease specialists and each question was analyzed by the NBME to ensure quality. Scores were equated and standardized to allow for comparability. Trainees and program directors were provided detailed feedback, including a list of the curricular competencies tested by those questions answered incorrectly. The ITE was administered 5,118 times. In 2013, the examination was taken by 1,969 fellows, representing 194 training programs. Among the 3 training years, there was consistency in the examination scores. Total test scores and scores within each of the content areas increased with each FIT year (there was a statistically significant difference in each cohort's average scale score across administration years). There was also significant improvement in examination scores across the fellowship years. The ACC ITE is a powerful tool available to all training programs to assess medical knowledge. This examination also delivers robust and timely feedback addressing individual knowledge gaps, and thus, may serve as a basis for improving training curricula.

To investigate the physical, knowledge and quality of life outcomes of an educational intervention for patients with early stage chronic kidney disease. A comprehensive predialysis education care team can be effective in slowing the progression of chronic kidney disease. A single group repeated measures design was used to evaluate the effects of the intervention. Participants were recruited through health department community health screen data banks. A predialysis, team-delivered educational intervention covering renal function health care, dietary management of renal function and the effects of Chinese herb medication on renal function was designed and implemented. Data were collected at baseline, six and 12 months. Study outcomes included physical indicators, knowledge (renal function protection, use of Chinese herbs and renal function and diet) and quality of life. Data were analysed using repeated measure anova to test for change over time in outcome variables. Sixty-six persons participated in this study. The predialysis educational intervention showed significant differences at the three time points in overall knowledge scores, waist-hip ratio, body mass index and global health status. Knowledge measures increased at month 6 and decreased at month 12. The primary indicator of renal function, glomerular filtration rate, remained stable throughout the 12 months of follow-up, despite the relatively older mean age of study participants. A predialysis education care team can provide effective disease-specific knowledge and may help retard deterioration of renal function in persons with early-stage chronic kidney disease. The intervention dose may need to be repeated every six months to maintain knowledge effects. A predialysis educational program with disease-specific knowledge and information is feasible and may provide positive outcomes for patients. Topics on the uses of Chinese herbs should be included for people who are likely to use alternative therapies.

Medical ontologies are expected to contribute to the effective use of medical information resources that store considerable amount of data. In this study, we focused on disease ontology because the complicated mechanisms of diseases are related to concepts across various medical domains. The authors developed a River Flow Model (RFM) of diseases, which captures diseases as the causal chains of abnormal states. It represents causes of diseases, disease progression, and downstream consequences of diseases, which is compliant with the intuition of medical experts. In this paper, we discuss a fact repository for causal chains of disease based on the disease ontology. It could be a valuable knowledge base for advanced medical information systems. We developed the fact repository for causal chains of diseases based on our disease ontology and abnormality ontology. This section summarizes these two ontologies. It is developed as linked data so that information scientists can access it using SPARQL queries through an Resource Description Framework (RDF) model for causal chain of diseases. We designed the RDF model as an implementation of the RFM for the fact repository based on the ontological definitions of the RFM. 1554 diseases and 7080 abnormal states in six major clinical areas, which are extracted from the disease ontology, are published as linked data (RDF) with SPARQL endpoint (accessible API). Furthermore, the authors developed Disease Compass, a navigation system for disease knowledge. Disease Compass can browse the causal chains of a disease and obtain related information, including abnormal states, through two web services that provide general information from linked data, such as DBpedia, and 3D anatomical images. Disease Compass can provide a complete picture of disease-associated processes in such a way that fits with a clinician's understanding of diseases. Therefore, it supports user exploration of disease knowledge with access to pertinent information from a variety of sources.

The movements of animals were analysed under the conceptual framework of graph theory in mathematics. The swine production related premises of Denmark were considered to constitute the nodes of a network and the links were the animal movements. In this framework, each farm will have a network of other premises to which it will be linked. A premise was a farm (breeding, rearing or slaughter pig), an abattoir or a trade market. The overall network was divided in premise specific subnets that linked the other premises from and to which animals were moved. This approach allowed us to visualise and analyse the three levels of organization related to animal movements that existed in the Danish swine production registers: the movement of animals between two premises, the premise specific networks, and the industry network. The analyses of animal movements were done using these three levels of organisation. The movements of swine were studied for the period September 30, 2002 to May 22, 2003. For daily movements of swine between two slaughter pig premises, the median number of pigs moved was 130 pigs with a maximum of 3306. For movements between a slaughter pig premise and an abattoir, the median number of pigs was 24. The largest percentage of movements was from farm to abattoir (82.5%); the median number of pigs per movement was 24 and the maximum number was 2018. For the whole period the median and maximum Euclidean distances observed in farm-to-farm movements were 22 km and 289 km respectively, while in the farm-to-abattoir movements, they were 36.2 km and 285 km. The network related to one specific premise showed that the median number of premises was mainly away from slaughter pig farms (3) or breeder farms (26) and mainly to an abattoir (1535). The assumption that animal movements can be randomly generated on the basis of farm density of the surrounding area of any farm is not correct since the patterns of animal movements have the topology of a scale-free network with a large degree of heterogeneity. This supported the opinion that the disease spread software assuming homogeneity in farm-to-farm relationship should only be used for large-scale interpretation and for epidemic preparedness. The network approach, based on graph theory, can be used efficiently to express more precisely, on a local scale (premise), the heterogeneity of animal movements. This approach, by providing network knowledge to the local veterinarian in charge of controlling disease spread, should also be evaluated as a potential tool to manage epidemics during the crisis. Geographic information systems could also be linked in the approach to produce knowledge about local transmission of disease.

Background: The lack of effective use of research evidence in policy-making is a major challenge in most low- and middle-income countries (LMICs). There is need to package research data into effective policy tools that will help policy-makers to make evidence-informed policy regarding infectious diseases of poverty (IDP). The objective of this study was to assess the usefulness of training workshops and mentoring to enhance the capacity of Nigerian health policy-makers to develop evidence-informed policy brief on the control of IDP. Methods: A modified "before and after" intervention study design was used in which outcomes were measured on the target participants both before the intervention is implemented and after. A 4-point Likert scale according to the degree of adequacy; 1 = "grossly inadequate," 4 = "very adequate" was employed. The main parameter measured was participants’ perceptions of their own knowledge/understanding. This study was conducted at subnational level and the participants were the career health policy-makers drawn from Ebonyi State in the South-Eastern Nigeria. A one-day evidence-to-policy workshop was organized to enhance the participants’ capacity to develop evidence-informed policy brief on IDP in Ebonyi State. Topics covered included collaborative initiative; preparation and use of policy briefs; policy dialogue; ethics in health policy-making; and health policy and politics. Results: The preworkshop mean of knowledge and capacity ranged from 2.49-3.03, while the postworkshop mean ranged from 3.42–3.78 on 4-point scale. The percentage increase in mean of knowledge and capacity at the end of the workshop ranged from 20.10%–45%. Participants were divided into 3 IDP mentorship groups (malaria, schistosomiasis, lymphatic filariasis [LF]) and were mentored to identify potential policy options/recommendations for control of the diseases for the policy briefs. These policy options were subjected to research evidence synthesis by each group to identify the options that have the support of research evidence (mostly systematic reviews) from PubMed, Cochrane database and Google Scholar. After the evidence synthesis, five policy options were selected out of 13 for malaria, 3 out of 10 for schistosomiasis and 5 out of 11 for LF. Conclusion: The outcome suggests that an evidence-to-policy capacity enhancement workshop combined with a mentorship programme can improve policy-makers’ capacity for evidence-informed policy-making (EIP).

Semantic networks for odors and colors in Alzheimer's disease.
Razani, Jill; Chan, Agnes; Nordin, Steven; Murphy, Claire
2010-05-01
Impairment in odor-naming ability and in verbal and visual semantic networks raised the hypothesis of a breakdown in the semantic network for odors in Alzheimer's disease (AD). The current study addressed this hypothesis. Twenty-four individuals, half patients with probable AD and half control participants, performed triadic-similarity judgments for odors and colors, separately, which, utilizing the multidimensional scaling (MDS) technique of individual difference scaling analysis (INDSCAL), generated two-dimensional configurations of similarity. The abilities to match odors and colors with written name labels were assessed to investigate disease-related differences in ability to identify and conceptualize the stimuli. In addition, responses on attribute-sorting tasks, requiring the odor and color perceptions to be categorized as one polarity of a certain dimension, were obtained to allow for objective interpretation of the MDS spatial maps. Whereas comparison subjects generated spatial maps based predominantly on relatively abstract characteristics, patients with AD classified odors on perceptual characteristics. The maps for patients with AD also showed disorganized groupings and loose associations between odors. Their normal configurations for colors imply that the patients were able to comprehend the task per se. The data for label matching and for attribute sorting provide further evidence for a disturbance in semantic odor memory in AD. The patients performed poorer than controls on both these odor tasks, implying that the ability to identify and/or conceptualize odors is impaired in AD. The results provide clear evidence for deterioration of the structure of semantic knowledge for odors in AD.

Objectives. To describe the development, implementation, and assessment of an advanced elective course on infectious diseases using active-learning strategies. Design. Pedagogy for active learning was incorporated by means of mini-lecture, journal club, and debate with follow-up discussion. Forty-eight students were enrolled in this 4-week elective course, in which 30% of course time was allocated for active-learning exercises. All activities were fundamentally designed as a stepwise approach in complementing each active-learning exercise. Assessment. Achievement of the course learning objectives was assessed using a 5-point Likert scale survey instrument. Students’ awareness of the significance of antimicrobial resistance was improved (p ≤ 0.05). Students’ ability to critically evaluate the infectious-disease literature and its application in informed clinical judgments was also enhanced through these active-learning exercises (p ≤ 0.05). Students agreed that active learning should be part of the pharmacy curriculum and that active-learning exercises improved their critical-thinking, literature-evaluation, and self-learning skills. Conclusion. An elective course using active-learning strategies allowed students to combine information gained from the evaluation of infectious-disease literature, critical thinking, and informed clinical judgment. This blended approach ultimately resulted in an increased knowledge and awareness of infectious diseases. PMID:22761528

The chances of raising crop productivity to enhance global food security would be greatly improved if we had a complete understanding of all the biological mechanisms that underpinned traits such as crop yield, disease resistance or nutrient and water use efficiency. With more crop genomes emerging all the time, we are nearer having the basic information, at the gene-level, to begin assembling crop gene catalogues and using data from other plant species to understand how the genes function and how their interactions govern crop development and physiology. Unfortunately, the task of creating such a complete knowledge base of gene functions, interaction networks and trait biology is technically challenging because the relevant data are dispersed in myriad databases in a variety of data formats with variable quality and coverage. In this paper we present a general approach for building genome-scale knowledge networks that provide a unified representation of heterogeneous but interconnected datasets to enable effective knowledge mining and gene discovery. We describe the datasets and outline the methods, workflows and tools that we have developed for creating and visualising these networks for the major crop species, wheat and barley. We present the global characteristics of such knowledge networks and with an example linking a seed size phenotype to a barley WRKY transcription factor orthologous to TTG2 from Arabidopsis, we illustrate the value of integrated data in biological knowledge discovery. The software we have developed (www.ondex.org) and the knowledge resources (http://knetminer.rothamsted.ac.uk) we have created are all open-source and provide a first step towards systematic and evidence-based gene discovery in order to facilitate crop improvement.

Background: Very few studies from India have studied stigma experienced by patients with schizophrenia. Aim of the Study: To study stigma in patients with schizophrenia (in the form of internalized stigma, perceived stigma and social-participation-restriction stigma) and its relationship with specified demographic and clinical variables (demographic variables, clinical profile, level of psychopathology, knowledge about illness, and insight). Materials and Methods: Selected by purposive random sampling, 100 patients with schizophrenia in remission were evaluated on internalized stigma of mental illness scale (ISMIS), explanatory model interview catalog stigma scale, participation scale (P-scale), positive and negative syndrome scale for schizophrenia, global assessment of functioning scale, scale to assess unawareness of mental disorder, and knowledge of mental illness scale. Results: On ISMIS scale, 81% patients experienced alienation and 45% exhibited stigma resistance. Stereotype endorsement was seen in 26% patients, discrimination experience was faced by 21% patients, and only 16% patients had social withdrawal. Overall, 29% participants had internalized stigma when total ISMIS score was taken into consideration. On P-scale, 67% patients experienced significant restriction, with a majority reporting moderate to mild restriction. In terms of associations between stigma and sociodemographic variables, no consistent correlations emerged, except for those who were not on paid job, had higher participation restriction. Of the clinical variables, level of functioning was the only consistent predictor of stigma. While better knowledge about the disorder was associated with lower level of stigma, there was no association between stigma and insight. Conclusion: Significant proportion of patients with schizophrenia experience stigma and stigma is associated with lower level of functioning and better knowledge about illness is associated with lower level of stigma.

An Integrative Bioinformatics Approach for Knowledge Discovery
NASA Astrophysics Data System (ADS)
Peña-Castillo, Lourdes; Phan, Sieu; Famili, Fazel
The vast amount of data being generated by large scale omics projects and the computational approaches developed to deal with this data have the potential to accelerate the advancement of our understanding of the molecular basis of genetic diseases. This better understanding may have profound clinical implications and transform the medical practice; for instance, therapeutic management could be prescribed based on the patient’s genetic profile instead of being based on aggregate data. Current efforts have established the feasibility and utility of integrating and analysing heterogeneous genomic data to identify molecular associations to pathogenesis. However, since these initiatives are data-centric, they either restrict the research community to specific data sets or to a certain application domain, or force researchers to develop their own analysis tools. To fully exploit the potential of omics technologies, robust computational approaches need to be developed and made available to the community. This research addresses such challenge and proposes an integrative approach to facilitate knowledge discovery from diverse datasets and contribute to the advancement of genomic medicine.

Most models determining how patient and caregiver characteristics and costs change with Alzheimer's disease (AD) progression focus on one aspect, for example, cognition. AD is inadequately defined by a single domain; tracking progression by focusing on a single aspect may mean other important aspects are insufficiently addressed. Dependence has been proposed as a better marker for following disease progression. This was a cross-sectional observational study (18 UK sites). Two hundred forty-nine community or institutionalized patients, with possible/probable AD, Mini-Mental State Examination (3-26), and a knowledgeable informant participated. Significant associations noted between dependence (Dependence Scale [DS]) and clinical measures of severity (cognition, function, and behavior). Bivariate and multivariate models demonstrated significant associations between DS and service use cost, patient quality of life, and caregiver perceived burden. The construct of dependence may help to translate the combined impact of changes in cognition, function, and behavior into a more readily interpretable form. The DS is useful for assessing patients with AD in clinical trials/research. Copyright © 2015 The Alzheimer's Association. Published by Elsevier Inc. All rights reserved.
A novel approach for data integration and disease subtyping
Tagett, Rebecca; Diaz, Diana
2017-01-01
Advances in high-throughput technologies allow for measurements of many types of omics data, yet the meaningful integration of several different data types remains a significant challenge. Another important and difficult problem is the discovery of molecular disease subtypes characterized by relevant clinical differences, such as survival. Here we present a novel approach, called perturbation clustering for data integration and disease subtyping (PINS), which is able to address both challenges. The framework has been validated on thousands of cancer samples, using gene expression, DNA methylation, noncoding microRNA, and copy number variation data available from the Gene Expression Omnibus, the Broad Institute, The Cancer Genome Atlas (TCGA), and the European Genome-Phenome Archive. This simultaneous subtyping approach accurately identifies known cancer subtypes and novel subgroups of patients with significantly different survival profiles. The results were obtained from genome-scale molecular data without any other type of prior knowledge. The approach is sufficiently general to replace existing unsupervised clustering approaches outside the scope of bio-medical research, with the additional ability to integrate multiple types of data.

A review is presented of data published in medical literature related to the screening used for the early detection of complex congenital heart disease in apparently healthy newborns in several cities of the world, including those reported in Mexico. The screening was performed due to the knowledge of the pathophysiology of indirect hypoxia data, observation of differential cyanosis and the consequent difference in the values of pre- and post-ductal pulse oximetry derived from the ductal and/or atrial septal defect dependence of several severe congenital heart diseases. Multicentre research studies have also been carried out on a massive scale, thus justifying the usefulness of the practice for its daily implementation and at international level. Additionally, legislative topics are cited in our country as part of the efforts to establish the mandatory nature of the screening throughout the Mexican Republic.

Over the last 10–15 years, our understanding of the composition and functions of the human gut microbiota has increased exponentially. To a large extent, this has been due to new ‘omic’ technologies that have facilitated large-scale analysis of the genetic and metabolic profile of this microbial community, revealing it to be comparable in influence to a new organ in the body and offering the possibility of a new route for therapeutic intervention. Moreover, it might be more accurate to think of it like an immune system: a collection of cells that work in unison with the host and that can promote health but sometimes initiate disease. This review gives an update on the current knowledge in the area of gut disorders, in particular metabolic syndrome and obesity-related disease, liver disease, IBD and colorectal cancer. The potential of manipulating the gut microbiota in these disorders is assessed, with an examination of the latest and most relevant evidence relating to antibiotics, probiotics, prebiotics, polyphenols and faecal microbiota transplantation.

Background Current guidelines for aerobic activity require that adults carry out ≥150 minutes/week of moderate-intensity physical activity, with a large body of epidemiologic evidence showing this level of activity to decrease the incidence of many chronic diseases. Less is known about whether light-intensity activities also have such benefits, and whether sedentary behavior is an independent predictor of increased risks of these chronic diseases, as imprecise assessments of these behaviours and cross-sectional study designs have limited knowledge to date. Methods Recent technological advances in assessment methods have made the use of movement sensors, such as the accelerometer, feasible for use in longitudinal, large-scale epidemiologic studies. Several such studies are collecting sensor-assessed, objective measures of physical activity with the aim of relating these to the development of clinical endpoints. This is a relatively new area of research; thus, in this paper, we use the Women’s Health Study (WHS) as a case study to illustrate challenges related to data collection, data processing, and analyses of the vast amount of data collected. Results The WHS plans to collect 7 days of accelerometer-assessed physical activity and sedentary behavior in ~18,000 women aged ≥62 years. Several logistical challenges exist in collecting data; nonetheless as of 31 August 2013, 11,590 women have already provided some data. Additionally, the WHS experience on data reduction and data analyses can help inform other similar large-scale epidemiologic studies. Conclusions Important data on the health effects of light-intensity activity and sedentary behaviour will emerge from large-scale epidemiologic studies collecting objective assessments of these behaviours.

In August 2015, the Corona outbreak caused by Middle East respiratory syndrome coronavirus (MERS-CoV) was the 9th episode since June 2012 in Saudi Arabia. Little is known about the public awareness toward the nature or prevention of the disease. The aim of this work was to assess the knowledge of the adult population in Riyadh toward the MERS-CoV. In this cross-sectional survey, a self-administrated questionnaire was distributed to randomly selected participants visiting malls in Riyadh. The questionnaire contained measurable epidemiological and clinical MERS-CoV knowledge level variables and relevant source of information. The study included 676 participants. Mean age was 32.5 (±SD 8.6) years and 353 (47.8%) were males. Almost all participants heard about the corona disease and causative agent. The study showed a fair overall knowledge (66.0%), less knowledge on epidemiological features of the disease (58.3%), and good knowledge (90.7%) on the clinical manifestation of the MERS-CoV. Internet was the major (89.0%) source of disease information, and other sources including health care providers, SMS, television, magazines and books were low rated (all <25%). In a multivariate logistic regression analysis age ≤30 years (Odds Ratio (OR)=1.647, 95%CI 1.048-2.584, P=0.030), male gender (OR=1.536, 95%CI 1.105-2.134, P=0.01), and no tertiary education (OR=1.957, 95%CI 1.264-3.030, P=0.003) were independent significant predictors of poor epidemiological knowledge. This study concludes that there was inadequate epidemiological knowledge received by the public and the reliance mostly on the clinical manifestations to recognizing the MERS-CoV disease. Comprehensive public health education programs is important to increase awareness of simple epidemiological determinants of the disease is warranted. Copyright © 2017. Published by Elsevier Ltd.

The potentially high costs of care associated with inflammatory bowel disease are recognized. A knowledge-based self-management approach seems to reduce health care costs, improve disease control, and reduce indirect costs. The aim of this study was to determine whether there is a significant association between patient knowledge and health care costs. Patients diagnosed with inflammatory bowel disease, Crohn's disease (CD), ulcerative colitis, or indeterminate colitis, in 2010 to 2011 were included. Direct costs were investigated for each patient, including costs of blood tests, procedures, medications, hospitalization, and visits. Specific prices were reported according to the hospital billing database for 2010. For medical and surgical hospital admissions, DRG 19 prices were reported. A validated questionnaire (CCKNOW) was used to assess disease-related knowledge. Ninety-one patients (38 men), mean age 47 years (range, 33-63 yr) were studied (14 indeterminate colitis, 33 CD, and 44 ulcerative colitis). Median cost for patients is higher in CD (&OV0556;4099.02). The mean overall CCKNOW score was 8.00 (8.50 for indeterminate colitis, 7.50 for CD, and 7.50 for ulcerative colitis). An increase of 5 points on the CCKNOW corresponds to a cost decrease of &OV0556;1099.53 in the first year of disease. Higher levels of knowledge were shown to be associated with significantly lower health care costs. The data suggest that better information could lead to better choices and improved outcomes; thus, patient information and education is a key priority for managing patients with inflammatory bowel disease, perhaps planning structured and formal patient education programs in the future.

2017-09-01
Health-care workers are at risk of exposure to occupational infections with subsequent risk of contracting diseases, disability, and even death. A systematic collection of occupational disease data is useful for monitoring current trends in work situations and disease exposures; however, these data are usually limited due to under-reporting. The objective of this study was to review literature related to knowledge, risk perceptions, and practices regarding occupational exposures to infectious diseases in Malaysian health-care settings, in particular regarding blood-borne infections, universal precautions, use of personal protective equipment, and clinical waste management. The data are useful for determining improvements in knowledge and risk perceptions among health-care workers with developments of health policies and essential interventions for prevention and control of occupational diseases.

Abstract In Taiwan, group tours are a popular mode of international travel; hence, group tour leaders must ensure traveler safety and health. This study identified factors influencing tour leaders’ willingness to recommend pretravel medical consultation and vaccination. A cross-sectional questionnaire survey was administered to tour leaders from January 2011 to December 2012. Multivariate logistic regression analyses were performed to estimate the odds ratios of having a positive attitude and willingness based on different knowledge scores of the tour leaders after adjustments for age, sex, education level, and seniority. Tour leaders with a more detailed knowledge of both travel-related infectious and noninfectious diseases demonstrated a higher willingness to receive vaccination. They believed that consultation at travel clinics before travel can improve travelers’ health (P < .05). This study supports the importance and effectiveness on educating tour leaders’ knowledge about travel-related diseases to improve health care for travelers. PMID:29419678

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

Popular perceptions and knowledge about cutaneous leishmaniasis and its treatment were studied in an endemic area of subtropical Northwest Ecuador. Although most of the adults surveyed were familiar with the disease, the vector, and traditional treatments, many showed a lack of knowledge about transmission of the disease, ulcer healing, and conventional treatment. Gender was found to have a significant impact on disease risk, perceptions, and treatment knowledge. Males experienced a risk of contracting cutaneous leishmaniasis that was almost triple that of women. Men were also more likely to perceive that the disease seriously diminished the victim's capacity to work. Women, on the other hand, were more prone to perceive that cutaneous leishmaniasis was a serious disease that significantly decreased self-esteem. Although 80% of the subjects knew at least one method of treating the disease, women tended to know more methods than men. Most of 150 different therapies reported involved the use of indigenous plants, chemicals, acids, antibiotics, heat treatments, or petroleum by-products. Some of these treatments could have clinical value. However, only 7% of the subjects knew about pentavalent antimonials. Almost 70% of the subjects with a past or present infection history were treated solely by traditional methods; only 12% received a full course of Glucantime, while 7.5% got an incomplete course. The findings indicate that it will be important to consider the identified gaps in knowledge and gender perceptions regarding the disease and its treatment when planning future control programs.
One Health, emerging infectious diseases and wildlife: two decades of progress?
Cunningham, Andrew A; Daszak, Peter; Wood, James L N

Infectious diseases affect people, domestic animals and wildlife alike, with many pathogens being able to infect multiple species. Fifty years ago, following the wide-scale manufacture and use of antibiotics and vaccines, it seemed that the battle against infections was being won for the human population. Since then, however, and in addition to increasing antimicrobial resistance among bacterial pathogens, there has been an increase in the emergence of, mostly viral, zoonotic diseases from wildlife, sometimes causing fatal outbreaks of epidemic proportions. Concurrently, infectious disease has been identified as an increasing threat to wildlife conservation. A synthesis published in 2000 showed common anthropogenic drivers of disease threats to biodiversity and human health, including encroachment and destruction of wildlife habitat and the human-assisted spread of pathogens. Almost two decades later, the situation has not changed and, despite improved knowledge of the underlying causes, little has been done at the policy level to address these threats. For the sake of public health and wellbeing, human-kind needs to work better to conserve nature and preserve the ecosystem services, including disease regulation, that biodiversity provides while also understanding and mitigating activities which lead to disease emergence. We consider that holistic, One Health approaches to the management and mitigation of the risks of emerging infectious diseases have the greatest chance of success.This article is part of the themed issue 'One Health for a changing world: zoonoses, ecosystems and human well-being'. © 2017 The Authors.

Owing to the shortages of inconvenience, expensive and high professional requirements etc. for conventional recognition devices of wheat leaf diseases, it does not satisfy the requirements of uploading and releasing timely investigation data in the large-scale field, which may influence the effectiveness of prevention and control for wheat diseases. In this study, a fast, accurate, and robust diagnose system of wheat leaf diseases based on android smartphone was developed, which comprises of two parts—the client and the server. The functions of the client include image acquisition, GPS positioning, corresponding, and knowledge base of disease prevention and control. The server includes image processing, feature extraction, and selection, and classifier establishing. The recognition process of the system goes as follow: when disease images were collected in fields and sent to the server by android smartphone, and then image processing of disease spots was carried out by the server. Eighteen larger weight features were selected by algorithm relief-F and as the input of Relevance Vector Machine (RVM), and the automatic identification of wheat stripe rust and powdery mildew was realized. The experimental results showed that the average recognition rate and predicted speed of RVM model were 5.56% and 7.41 times higher than that of Support Vector Machine (SVM). And application discovered that it needs about 1 minute to get the identification result. Therefore, it can be concluded that the system could be used to recognize wheat diseases and real-time investigate in fields.

Background There is increasing scientific knowledge about the interaction between physiological (musculoskeletal, neuromuscular, cognitive and sensory) systems and their influence on balance and walking impairments in Parkinson’s disease. We have developed a new conceptual framework for balance training, emphasising specific components of balance control related to Parkinson’s disease symptoms by using highly challenging, progressive and varying training conditions. The primary aim of this proposed randomised controlled trial will be to investigate the short-term and long-term effects of a 10-week balance training regime in elderly with Parkinson’s disease. Methods/Design Eighty participants with mild to moderate idiopathic Parkinson’s disease will be recruited and randomly allocated to an intervention group receiving balance training or a control group whose participants will continue to receive their usual care. The intervention will consist of a 10-week group training regime (1-hour training, three times per week), which will be led by two physiotherapists to ensure training progression and safety. The conceptual framework will be applied by addressing specific balance components (sensory integration, anticipatory postural adjustments, motor agility, stability limits) through varying training conditions and structured progression. Assessment will be conducted through a multi-dimensional battery of outcomes, prior to and immediately after the 10-week intervention, and at 9 and 15 months’ follow-up after entering the study. Primary outcome measures will be balance performance (assessed using the Mini Balance Evaluation Systems Test), change in gait velocity (m/s) between single and dual task walking, and fear of falling (evaluated using the Fall Efficacy Scale International). Discussion This study has the potential to provide new insight and knowledge of the effects of specific, varied and challenging balance training on a wide health spectrum in elderly with PD. If found to be effective, this pragmatic approach with translation of theory into practice, can be implemented in existing outpatient care. Trial registration NCT01417598 PMID:23017069
Improving Smallholder Farmer Biosecurity in the Mekong Region Through Change Management.
Young, J R; Evans-Kocinski, S; Bush, R D; Windsor, P A
2015-10-01
Transboundary animal diseases including foot-and-mouth disease and haemorrhagic septicaemia remain a major constraint for improving smallholder large ruminant productivity in the Mekong region, producing negative impacts on rural livelihoods and compromising efforts to reduce poverty and food insecurity. The traditional husbandry practices of smallholders largely exclude preventive health measures, increasing risks of disease transmission. Although significant efforts have been made to understand the social aspects of change development in agricultural production, attention to improving the adoption of biosecurity has been limited. This study reviews smallholder biosecurity risk factors identified in the peer-reviewed literature and from field research observations conducted in Cambodia and Laos during 2006-2013, considering these in the context of a change management perspective aimed at improving adoption of biosecurity measures. Motivation for change, resistance to change, knowledge management, cultural dimensions, systems theory and leadership are discussed. Due to geographical, physical and resource variability, the implementation of biosecurity interventions suitable for smallholders is not a 'one size fits all'. Smallholders should be educated in biosecurity principles and empowered to make personal decisions rather than adopt prescribed pre-defined interventions. Biosecurity interventions should be aligned with smallholder farmer motivations, preferably offering clear short-term risk management benefits that elicit interest from smallholders. Linking biosecurity and disease control with improved livestock productivity provides opportunities for sustainable improvements in livelihoods. Participatory research and extension that improves farmer knowledge and practices offers a pathway to elicit sustainable broad-scale social change. However, examples of successes need to be communicated both at the 'evidence-based level' to influence regional policy development and at the village or commune level, with 'champion farmers' and 'cross-visits' used to lead local change. The adoption of applied change management principles to improving regional biosecurity may assist current efforts to control and eradicate transboundary diseases in the Mekong region. © 2013 Blackwell Verlag GmbH.
The Genetics of Ischemic Heart Disease: From Current Knowledge to Clinical Implications.
Elosua, Roberto; Sayols-Baixeras, Sergi
2017-09-01
Ischemic heart disease continues to cause high morbidity and mortality. Its prevalence is expected to increase due to population aging, and its prevention is a major goal of health policies. The risk of developing ischemic heart disease is related to a complex interplay between genetic, environmental, and lifestyle factors. In the last decade, considerable progress has been made in knowledge of the genetic architecture of this disease. This narrative review provides an overview of current knowledge of the genetics of ischemic heart disease and of its translation to clinical practice: identification of new therapeutic targets, assessment of the causal relationship between biomarkers and disease, improved risk prediction, and identification of responders and nonresponders to specific drugs (pharmacogenomics).

Formalizing Knowledge in Multi-Scale Agent-Based Simulations
Somogyi, Endre; Sluka, James P.; Glazier, James A.
2017-01-01
Multi-scale, agent-based simulations of cellular and tissue biology are increasingly common. These simulations combine and integrate a range of components from different domains. Simulations continuously create, destroy and reorganize constituent elements causing their interactions to dynamically change. For example, the multi-cellular tissue development process coordinates molecular, cellular and tissue scale objects with biochemical, biomechanical, spatial and behavioral processes to form a dynamic network. Different domain specific languages can describe these components in isolation, but cannot describe their interactions. No current programming language is designed to represent in human readable and reusable form the domain specific knowledge contained in these components and interactions. We present a new hybrid programming language paradigm that naturally expresses the complex multi-scale objects and dynamic interactions in a unified way and allows domain knowledge to be captured, searched, formalized, extracted and reused.

The London Chest Activities of Daily Living Scale measures the impact of breathlessness on both activity and social functioning. However, the London Chest Activities of Daily Living Scale is not routinely used in patients with advanced disease. To assess the psychometric properties of the London Chest Activities of Daily Living Scale in patients with refractory breathlessness due to advanced disease. A cross-sectional secondary analysis of data from a randomised controlled parallel-group, pragmatic, single-blind fast-track trial (randomised controlled trial) investigating the effectiveness of an integrated palliative and respiratory care service for patients with advanced disease and refractory breathlessness, known as the Breathlessness Support Service (NCT01165034). All patients completed the following questionnaires: the London Chest Activities of Daily Living Scale, Chronic Respiratory Questionnaire, the Palliative care Outcome Scale, Palliative care Outcome Scale-symptoms, the Hospital Anxiety and Depression Scale and breathlessness measured on a numerical rating scale. Data quality, scaling assumptions, acceptability, internal consistency and construct validity of the London Chest Activities of Daily Living Scale were determined using standard psychometric approaches. Breathless patients with advanced malignant and non-malignant disease. A total of 88 patients were studied, primary diagnosis included; chronic obstructive pulmonary disease = 53, interstitial lung disease = 17, cancer = 18. Median (range) London Chest Activities of Daily Living Scale total score was 46.5 (14-67). No floor or ceiling effect was observed for the London Chest Activities of Daily Living Scale total score. Internal consistency was good, and Cronbach's alpha for the London Chest Activities of Daily Living Scale total score was 0.90. Construct validity was good with 13 out of 15 a priori hypotheses met. Psychometric analyses suggest that the London Chest Activities of Daily Living Scale is acceptable, reliable and valid in patients with advanced disease and refractory breathlessness.

Prediabetes mellitus (pre-DM) is an important predictive indicator of Type 2 diabetes. A person with pre-DM is eight times more likely to develop diabetes than a person without pre-DM. Prior research suggests that proactive interventions may delay the progression of this disease and reduce the rate of disease development. The purposes of this preliminary study were to develop a multitheory-driven lifestyle intervention protocol for adults with pre-DM and to evaluate its feasibility and impacts on knowledge regarding pre-DM, dietary behaviors, and physical activity (primary outcomes) as well as to describe the disease progression indicators (secondary outcomes). A single-group, longitudinal study design was used. Thirty-nine participants were included in the analysis. A generalized estimating equation model was used to determine the trends in changes in the outcomes. All of the participants underwent testing at baseline (T0) and at 3 (T1), 6 (T2), and 12 (T3) months after the 4-week lifestyle intervention. There were significantly increasing trends for each study parameter (Pre-DM Knowledge Assessment Form-12, p < .01; Dietary Behavior Scale, p < .01) and significantly positive changes in body weight (p < .01), body mass index (p < .01), fasting glucose level (p < .01), and glycated hemoglobin level (p < .01) over the 12-month study period. This study supports the feasibility of the developed multitheory-driven lifestyle intervention protocol and suggests that its application may improve the effectiveness of diabetes prevention programs in clinical settings. Further randomized controlled trials are needed.

Early assessment and management of risk factors is known to have significant impact in preventing cardiovascular disease (CVD) and its associated burden. Cardiovascular disease risk assessment and management (CVDRAM) is best approached by teamwork across health care professionals. This study aimed at assessing health care students’ (HCSs) knowledge about the parameters needed for estimating CVD risk, their self-assessed preparedness/confidence and perceived barriers for the provision of CVDRAM services through a survey administered to third and fourth year pharmacy, medical, and nursing students in Qatar. Although all student cohorts achieved similar knowledge scores, less than half (n = 38, 47%) were able to identify all of the six main risk factors necessary to estimate absolute CVD risk, and a third (32%) were unable to identify total cholesterol as an independent risk factor necessary to estimate CVD risk. Training on the use of CVD risk assessment tools differed among the three student cohorts. All student cohorts also perceived similar levels of preparedness in CVDRAM. However, pharmacy students reported the highest preparedness/confidence with the use of the latest CVDRAM guidelines. The majority of statements listed under the barriers scale were perceived by the students as being moderate (median score = 3). Poor public acceptance or unawareness of importance of estimating CVD risk was the only barrier perceived as a major by nursing students. Future integration of interprofessional educational (IPE) activities in the CVDRAM curricula of HCSs may be a suitable strategy to minimize barriers and foster collaborative practice for the provision of CVDRAM services in Qatar.

Diabetes knowledge has been shown to improve glycemic control and associate with several demographic parameters. In Greece, a country with high obesity rates, disease knowledge has never been evaluated in diabetic patients. This cross sectional study aimed to assess diabetes knowledge and its associations between social and demographic parameters, among Greek type 2 diabetes mellitus (T2DM) patients. One hundred fifty nine patients with T2DM were recruited from an urban and a rural clinic in Greece. Diabetes knowledge was assessed with the Brief Diabetes Knowledge Test (DKT). Basic anthropometry was performed. Data regarding glycemic control and sociodemographic characteristics were collected from the patients' medical files. Greek T2DM patients demonstrated poor disease knowledge (mean DKT score 8.3±2.2/14.0 and mean DKT as a percent of correct answers 59.6±15.8%). No differences were observed between sex, place of residence, or glycemic control, among subjects. Patients with higher education demonstrated greater diabetes knowledge. Simple obesity with concurrent central obesity or suboptimal glycemic control decreased diabetes knowledge among participants. Additionally, waist circumference was inversely correlated to diabetes knowledge. Based on the DKT, Greek patients exhibit poor diabetes knowledge. This study provides evidence for the need for better diabetes education in order to ameliorate disease outcome. Copyright © 2016 SEEN. Publicado por Elsevier España, S.L.U. All rights reserved.

Wildlife diseases pose an increasing threat to biodiversity and are a major management challenge. A striking example of this threat is the emergence of chytridiomycosis. Despite diagnosis of chytridiomycosis as an important driver of global amphibian declines 15 years ago, researchers have yet to devise effective large-scale management responses other than biosecurity measures to mitigate disease spread and the establishment of disease-free captive assurance colonies prior to or during disease outbreaks. We examined the development of management actions that can be implemented after an epidemic in surviving populations. We developed a conceptual framework with clear interventions to guide experimental management and applied research so that further extinctions of amphibian species threatened by chytridiomycosis might be prevented. Within our framework, there are 2 management approaches: reducing Batrachochytrium dendrobatidis (the fungus that causes chytridiomycosis) in the environment or on amphibians and increasing the capacity of populations to persist despite increased mortality from disease. The latter approach emphasizes that mitigation does not necessarily need to focus on reducing disease-associated mortality. We propose promising management actions that can be implemented and tested based on current knowledge and that include habitat manipulation, antifungal treatments, animal translocation, bioaugmentation, head starting, and selection for resistance. Case studies where these strategies are being implemented will demonstrate their potential to save critically endangered species. © 2014 Society for Conservation Biology.
Nanomechanical properties of single amyloid fibrils

Amyloid fibrils are traditionally associated with neurodegenerative diseases like Alzheimer’s disease, Parkinson’s disease or Creutzfeldt-Jakob disease. However, the ability to form amyloid fibrils appears to be a more generic property of proteins. While disease-related, or pathological, amyloid fibrils are relevant for understanding the pathology and course of the disease, functional amyloids are involved, for example, in the exceptionally strong adhesive properties of natural adhesives. Amyloid fibrils are thus becoming increasingly interesting as versatile nanobiomaterials for applications in biotechnology. In the last decade a number of studies have reported on the intriguing mechanical characteristics of amyloid fibrils. In most of these studies atomic force microscopy (AFM) and atomic force spectroscopy play a central role. AFM techniques make it possible to probe, at nanometer length scales, and with exquisite control over the applied forces, biological samples in different environmental conditions. In this review we describe the different AFM techniques used for probing mechanical properties of single amyloid fibrils on the nanoscale. An overview is given of the existing mechanical studies on amyloid. We discuss the difficulties encountered with respect to the small fibril sizes and polymorphic behavior of amyloid fibrils. In particular, the different conformational packing of monomers within the fibrils leads to a heterogeneity in mechanical properties. We conclude with a brief outlook on how our knowledge of these mechanical properties of the amyloid fibrils can be exploited in the construction of nanomaterials from amyloid fibrils.

A workshop sponsored by the National Institute of Diabetes and Digestive and Kidney Diseases and the National Institute of Biomedical Imaging and Bioengineering focused on research gaps and opportunities in the development of new biomarkers of pancreatic disease. The session was held on July 22, 2015, and structured into six sessions: 1) introduction and overview, 2) keynote address, 3) new approaches to the diagnosis of chronic pancreatitis, 4) biomarkers of pain and inflammation, 5) new approaches to the detection of pancreatic cancer, and 6) shed exosomes, shed cells, and shed proteins. Recent advances in the fields of pancreatic imaging, functional markers of pancreatic disease, proteomics, molecular and cellular imaging, and detection of circulating cancer cells and exosomes were reviewed. Knowledge gaps and research needs were highlighted. The development of new methods for the non-invasive determination of pancreatic pathology, the use of cellular markers of pancreatic function, inflammation, pain, and malignancy, and the refinement of methods to identify cells and cellular constituents of pancreatic cancer were discussed. The further refinement of sophisticated technical methods, and the need for clinical studies to validate these new approaches in large-scale studies of patients at risk for the development of pancreatic disease was repeatedly emphasized.

To evaluate the validity, reliability, and acceptability of the brief version of the self-management knowledge, attitude, and behavior (KAB) assessment scale for diabetes patients. Diabetes patients who were managed at the Xinkaipu Community Health Service Center of Tianxin in Changsha, Hunan Province were selected for survey by cluster sampling. A total of 350 diabetes patients were surveyed using the brief scale to collect data on knowledge, attitudes, and behaviors of self-management. Content validity was evaluated by Pearson correlation coefficient between the brief scale and subscales of knowledge, attitude, and behavior. Structure validity was evaluated by factor analysis, and discrimination validity was evaluated by an independent sample t-test between the high-score and low-score groups. Reliability was tested by internal consistency reliability and split-half reliability. The evaluation indexes of internal consistency reliability were Cronbach's α coefficients, θ coefficient, and Ω coefficient. Acceptability was evaluated by valid response rate and completion time of the brief scale. A total of 346(98.9%) valid questionnaires were returned, with average survey time of (11.43±3.4) minutes. Average score of the brief scale was 78.85 ± 11.22; scores of the knowledge, attitude, and behavior subscales were 16.45 ± 4.42, 21.33 ± 2.03, and 41.07 ± 8.34, respectively. Pearson correlation coefficients between the brief scale and the knowledge, attitude, and behavior subscales were 0.92, 0.42, and 0.60, respectively; P-values were all less than 0.01, indicating that the face validity and content validity of the brief scale were achieved to a good level. The common factor cumulative variance contribution rate of the brief scale and three subscales was from 53.66% to 61.75%, which achieved more than 50% of the approved standard. There were 11 common factors; 41 of the total 42 items had factor loadings above 0.40 in their relevant common factor, indicating that the brief scale and three subscales had good construct validity. Patients were divided into a high-score group and a low-score group, then scores of the brief scale and three subscales were compared between the groups using a t-test. The results were all significant, indicating that the brief scale and three subscales had good discriminate validity. Mean scores of the brief scale and three subscales of the high-score group were 91.55±6.81, 19.51±2.17, 22.74±1.88, and 49.30±6.20, respectively; these were higher than the low-score group (65.89±5.79, 12.29±4.76, 20.22±1.88, and 33.39±6.17, respectively) with t-values 27.76, 13.31, 9.20, and 17.56 (P-values were less than 0.001). The Cronbach's α coefficient, θ coefficient, Ω coefficient, and split-half reliability of the brief scale were 0.83, 0.87, 0.96, and 0.84, respectively. These values for the three subscales were all above 0.70, except for the θ coefficient of the attitude subscale with 0.64, indicating that the brief scale and three subscales had acceptable internal consistency reliability. The brief version of the diabetes self-management knowledge, attitude, and behavior assessment scale showed good acceptability, validity, and reliability, to responsibly evaluate self-management KAB among patients with diabetes.

Hispanic clinicians in Texas, United States of America, and in the neighboring state of Nuevo Leon, Mexico, were surveyed to determine their educational needs in the area of HIV/AIDS. Two-thirds of the 74 Texan and 22% of the 104 Mexican physicians queried had seen at least one HIV/AIDS patient in the previous year. The majority of the respondents were primary care physicians who: 1) were in private practice; 2) saw more than 1,000 patients per year; 3) had been out of training for more than 10 years; 4) provided some HIV prevention education to patients based on their perceived risk of infection; 5) rated their own knowledge of HIV/AIDS as average but rated their knowledge of treatments for the disease below average; 6) received most of their information about HIV/AIDS from journals rather than formal continuing education programs; 7) thought Hispanic patients had special needs with regard to HIV/AIDS care; and 8) were willing to attend education programs to improve their HIV/AIDS management skills. The greatest barriers to caring for HIV patients were lack of clinical knowledge and fear of infection. These results point to a need for a large-scale training program to improve the HIV/AIDS management skills of Hispanic clinicians in Texas and Nuevo Leon.

A name change for schizophrenia was first implemented in Japan for reducing stigma in 2002; however, little is known of its long-term impact. Total 259 students from 20 universities answered an anonymous self-administered questionnaire about their mental health-related experiences, and stigma scales including feasible knowledge and negative stereotypes for four specific diseases, including schizophrenia (old and new names), depression, and diabetes mellitus. We also asked to choose the old and new names of schizophrenia and dementia among ten names for mental and physical illnesses and conditions. The participants had more feasible knowledge and fewer negative stereotypes for the new name of schizophrenia than the old name, but were still significantly worse than for depression and diabetes mellitus (p < 0.01). Direct contact experiences with those who have mental health problems were associated with feasible knowledge for schizophrenia but not negative stereotypes (β = 0.13, p = 0.020). The rate of correct responses for the old and new names of schizophrenia was significantly lower than that of dementia (41 vs. 87%, p < 0.001). Mental health-related experience from media was associated with the recognition of name change for schizophrenia (p = 0.008), which was associated with less feasible knowledge for new name of schizophrenia. The name change of schizophrenia has reduced stigma since 12 years have passed. More effective campaigns, educational curricula, and policy making are needed to reduce stigma toward schizophrenia.

Background Non-communicable diseases (NCDs) are a leading cause of death among adults in sub-Saharan Africa, and chronic kidney disease (CKD) is a growing public health threat. Understanding knowledge, attitudes, and practices associated with NCDs is vital to informing optimal policy and public health responses in the region, but few community-based assessments have been performed for CKD. To address this gap, we conducted a cross-sectional survey of adults in northern Tanzania using a validated instrument. Methods Between January and June 2014, we administered a structured survey to a random sample of adults from urban and rural communities. The validated instrument consisted of 25 items designed to measure knowledge, attitudes, and practices associated with kidney disease. Participants were also screened for CKD, diabetes, hypertension, and human immunodeficiency virus. Results We enrolled 606 participants from 431 urban and rural households. Knowledge of the etiologies, symptoms, and treatments for kidney disease was low (mean score 3.28 out of 10; 95% CI 2.94, 3.63). There were no significant differences by CKD status. Living in an urban setting and level of education had the strongest independent associations with knowledge score. Attitudes were characterized by frequent concern about the health (27.3%; 20.2, 36.0%), economic (73.1%; 68.2, 77.5%), and social impact (25.4%; 18.6, 33.6%) of kidney disease. Practices included the use of traditional healers (15.2%; 9.1, 24.5%) and traditional medicines (33.8%; 25.0, 43.9%) for treatment of kidney disease as well as a willingness to engage with mobile-phone technology in CKD care (94.3%; 90.1, 96.8%). Conclusions Community-based adults in northern Tanzania have limited knowledge of kidney disease. However, there is a modest knowledge base upon which to build public health programs to expand awareness and understanding of CKD, but these programs must also consider the variety of means by which adults in this population meet their healthcare needs. Finally, our assessment of local attitudes suggested that such public health efforts would be well-received. PMID:27280584

2018-01-01
The goal of this study is to discover disease co-occurrence and sequence patterns from large scale cancer diagnosis histories in New York State. In particular, we want to identify disparities among different patient groups. Our study will provide essential knowledge for clinical researchers to further investigate comorbidities and disease progression for improving the management of multiple diseases. We used inpatient discharge and outpatient visit records from the New York State Statewide Planning and Research Cooperative System (SPARCS) from 2011-2015. We grouped each patient's visit history to generate diagnosis sequences for seven most popular cancer types. We performed frequent disease co-occurrence mining using the Apriori algorithm, and frequent disease sequence patterns discovery using the cSPADE algorithm. Different types of cancer demonstrated distinct patterns. Disparities of both disease co-occurrence and sequence patterns were observed from patients within different age groups. There were also considerable disparities in disease co-occurrence patterns with respect to different claim types (i.e., inpatient, outpatient, emergency department and ambulatory surgery). Disparities regarding genders were mostly found where the cancer types were gender specific. Supports of most patterns were usually higher for males than for females. Compared with secondary diagnosis codes, primary diagnosis codes can convey more stable results. Two disease sequences consisting of the same diagnoses but in different orders were usually with different supports. Our results suggest that the methods adopted can generate potentially interesting and clinically meaningful disease co-occurrence and sequence patterns, and identify disparities among various patient groups. These patterns could imply comorbidities and disease progressions.
Informed choice: understanding knowledge in the context of screening uptake.
Michie, Susan; Dormandy, Elizabeth; Marteau, Theresa M

This study evaluates a scale measuring knowledge about a screening test and investigates the association between knowledge, uptake and attitudes towards screening. One thousand four hundred ninety-nine pregnant women completed the knowledge scale of the multidimensional measure of informed choice (MMIC). Three hundred forty-five of these women and 152 professionals providing antenatal care also rated the importance of the knowledge items. Item characteristic curves show that, with one exception, the knowledge items reflect a spread of difficulty and are able to discriminate between people. All items were seen as essential or helpful by both women and health professionals, with two items seen as particularly important and one as unimportant. There were some differences between health professionals, women with low risk results and women with high risk results. Knowledge was not associated with uptake, attitude, or the extent to which uptake was consistent with women's attitudes towards undergoing the test.

Clinical management of comorbidities is a challenge, especially in a clinical decision support setting, as it requires the safe and efficient reconciliation of multiple disease-specific clinical procedures to formulate a comorbid therapeutic plan that is both effective and safe for the patient. In this paper we pursue the integration of multiple disease-specific Clinical Practice Guidelines (CPG) in order to manage co-morbidities within a computerized Clinical Decision Support System (CDSS). We present a CPG integration framework-termed as COMET (Comorbidity Ontological Modeling & ExecuTion) that manifests a knowledge management approach to model, computerize and integrate multiple CPG to yield a comorbid CPG knowledge model that upon execution can provide evidence-based recommendations for handling comorbid patients. COMET exploits semantic web technologies to achieve (a) CPG knowledge synthesis to translate a paper-based CPG to disease-specific clinical pathways (CP) that include specialized co-morbidity management procedures based on input from domain experts; (b) CPG knowledge modeling to computerize the disease-specific CP using a Comorbidity CPG ontology; (c) CPG knowledge integration by aligning multiple ontologically-modeled CP to develop a unified comorbid CPG knowledge model; and (e) CPG knowledge execution using reasoning engines to derive CPG-mediated recommendations for managing patients with comorbidities. We present a web-accessible COMET CDSS that provides family physicians with CPG-mediated comorbidity decision support to manage Atrial Fibrillation and Chronic Heart Failure. We present our qualitative and quantitative analysis of the knowledge content and usability of COMET CDSS.

In large scale cooking, food is handled by many individuals, thereby increasing the chances of food contamination due to improper handling. Deliberate or accidental contamination of food during large scale production might endanger the health of consumers, and have very expensive repercussions on a country. The purpose of this study was to evaluate the food safety knowledge, attitudes, and practices among institutional food- handlers in Ghana. The study was conducted using a descriptive, cross-sectional survey of 29 institutions by conducting face to face interview and administration of questionnaire to two hundred and thirty-five (235) institutional food-handlers. The questionnaire was peer-reviewed and pilot tested in three institutions in the Upper East Region of Ghana, before the final version was distributed to food-handlers. The questionnaire was structured into five distinctive parts to collect information on (i) demographic characteristics, (ii) employees' work satisfaction, (iii) knowledge on food safety, (iv) attitudes towards food safety and (v) food hygiene practices. Majority of the food-handlers were between 41-50 years (39.1%). Female respondents were (76.6%). In our study, the food-handlers were knowledgeable about hygienic practices, cleaning and sanitation procedures. Almost all of the food-handlers were aware of the critical role of general sanitary practices in the work place, such as hand washing (98.7% correct answers), using gloves (77.9%), proper cleaning of the instruments/utensils (86.4%) and detergent use (72.8%). On disease transmission, the results indicates that 76.2% of the food- handlers did not know that Salmonella is a food borne pathogens and 70.6% did not know that hepatitis A is a food borne pathogen. However, 81.7% handlers agreed that typhoid fever is transmitted by food and 87.7% agreed that bloody diarrhea is transmitted by food. Logistic regression analysis testing four models showed statistically significant differences (p < 0.05), for models in which the explanatory variable was the level of education. In generally, the institutional food-handlers have satisfactory knowledge in food safety but this does not translate into strict hygienic practices during processing and handling food products.

The aim of this study was to design a theory-based educational program for adolescents with inflammatory bowel disease (IBD) using an interactive multimedia CD-ROM and to test its effectiveness in improving knowledge in IBD. Curriculum-based instruction using educational theory and principles was designed for adolescents on an interactive multimedia CD-ROM. Twenty subjects completed summative evaluation of the CD-ROM measuring gain in knowledge about IBD immediately and 9 months after instruction. Subjects found the CD-ROM to be informative, appealing, and easy to use. The mean baseline score of the adolescents on the Crohn's and Colitis Knowledge questionnaire was 12.2 (standard deviation 5.14, range 3-24). After an average of 30 minutes of self-directed learning, adolescent subjects increased their posttest score to a mean of 19.8, a gain of 7.6 points over baseline (95% confidence interval 5.2-10.1, P < 0.0001). Knowledge of medications, disease complications, and gastrointestinal structure and function was gained and retained upon retesting at 9 months with a mean Crohn's and Colitis Knowledge questionnaire score of 17.5 (standard deviation 3.9, range 12-26), which was still an improvement over the mean pretest knowledge score of 12.2 (P < 0.001). Adolescents with IBD have low baseline knowledge about their disease. A rigorously developed interactive educational tool is now available for instructing adolescent patients about their IBD.

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

An effective patient-physician relationship is important in the management of psoriatic patients. Our purpose was to investigate the efficacy of an educational intervention for patients with psoriasis in improving disease knowledge and attitude towards physicians and systemic treatments. The intervention consisted of a single, 2-hour educational programme conducted either by a dermatologist or by a dermatologist and a psychologist. Information on psoriasis and its treatment was given. A questionnaire concerning knowledge about psoriasis was administered before and after the programme, and after 6 months. 123 patients were enrolled. They reported a high degree of satisfaction with the intervention, improvement in knowledge about the disease and a better attitude towards therapy. After 6 months a better knowledge about the disease and a higher attitude to treatment were retained. A single educational intervention may be helpful in improving psoriasis knowledge and give psychological relief to patients. Copyright 2009 S. Karger AG, Basel.
Multi-criteria Decision Analysis to Model Ixodes ricinus Habitat Suitability.

Tick-borne diseases present a major threat to both human and livestock health throughout Europe. The risk of infection is directly related to the presence of its vector. Thereby it is important to know their distribution, which is strongly associated with environmental factors: the presence and availability of a suitable habitat, of a suitable climate and of hosts. The present study models the habitat suitability for Ixodes ricinus in Ireland, where data on tick distribution are scarce. Tick habitat suitability was estimated at a coarse scale (10 km) with a multi-criteria decision analysis (MCDA) method according to four different scenarios (depending on the variables used and on the weights granted to each of them). The western part of Ireland and the Wicklow mountains in the East were estimated to be the most suitable areas for I. ricinus in the island. There was a good level of agreement between results from the MCDA and recorded tick presence. The different scenarios did not affect the spatial outputs substantially. The current study suggests that tick habitat suitability can be mapped accurately at a coarse scale in a data-scarce context using knowledge-based methods. It can serve as a guideline for future countrywide sampling that would help to determine local risk of tick presence and refining knowledge on tick habitat suitability in Ireland.

In Honduras, where Chagas disease is a serious health and environmental concern, prevention measures face the challenge of achieving widespread and long-term sustainable adoption by communities. The article integrates social network analysis and a gender-sensitive approach to understand the role of men and women in the implementation of a community-level intervention, based on the adoption of housing improvements to reduce the presence of the insect vector. A total of 108 people in the community of El Salitre were interviewed. Data were collected on socio-demographic characteristics, participation in project activities, communication and collaboration networks related to Chagas disease prevention, knowledge of Chagas disease, and adoption of housing improvements techniques. Communication mostly occurred between the same gender individuals and was associated with knowledge of Chagas disease. Socioeconomic status, Chagas disease knowledge, and collaboration with men were associated with women adopting housing improvements. For men, however, participation in project activities, formal education, and collaboration with women were associated with adoption. These findings suggest that men and women were driven by distinct concerns, interests, and motivations when adopting new Chagas disease prevention strategies. Participatory community interventions that seek to generate health knowledge and foster collaborations to reduce health risk should address gender differences.
Discussion on calculation of disease severity index values from scales with unequal intervals
USDA-ARS?s Scientific Manuscript database
When estimating severity of disease, a disease interval (or category) scale comprises a number of categories of known numeric values – with plant disease this is generally the percent area with symptoms (e.g., the Horsfall-Barratt (H-B) scale). Studies in plant pathology and plant breeding often use...

"Facts for Life" is an essential tool for saving the lives of children. In this study we wanted to evaluate the knowledge of "Facts for Life" among Turkish women. This is a cross-sectional field study. We used 25 indicator questions to evaluate the knowledge of women in the following main subjects: safe motherhood, childhood immunization, childhood diarrhoea, children's acute respiratory diseases, and household hygiene. We filled out printed questionnaires during face-to-face interviews. For each correct answer we gave 4 points, and the sum of the points was accepted as the knowledge score. Bursa metropolitan area in Turkey. Married women between 15-44 years of age. We selected 1000 of them from the household cards of the health centers that were located at the Bursa metropolitan area by using a random selection method. Mean knowledge score was 72.0 +/- 0.3. About 3/5 had moderate, 1/5 good + very good, and 1/5 bad knowledge scores. Childhood diarrhoea was better known than acute respiratory diseases. The very well known "Facts for Life" were those concerning food and household hygiene. Women's knowledge about "Facts for Life" was at a moderate level. The knowledge level of older women was better than the younger. Some false beliefs still existed. Knowledge about ARI and diarrhoeal diseases in childhood were the least known facts.

Background: The London Chest Activities of Daily Living Scale measures the impact of breathlessness on both activity and social functioning. However, the London Chest Activities of Daily Living Scale is not routinely used in patients with advanced disease. Aim: To assess the psychometric properties of the London Chest Activities of Daily Living Scale in patients with refractory breathlessness due to advanced disease. Design: A cross-sectional secondary analysis of data from a randomised controlled parallel-group, pragmatic, single-blind fast-track trial (randomised controlled trial) investigating the effectiveness of an integrated palliative and respiratory care service for patients with advanced disease and refractory breathlessness, known as the Breathlessness Support Service (NCT01165034). All patients completed the following questionnaires: the London Chest Activities of Daily Living Scale, Chronic Respiratory Questionnaire, the Palliative care Outcome Scale, Palliative care Outcome Scale–symptoms, the Hospital Anxiety and Depression Scale and breathlessness measured on a numerical rating scale. Data quality, scaling assumptions, acceptability, internal consistency and construct validity of the London Chest Activities of Daily Living Scale were determined using standard psychometric approaches. Setting/participants: Breathless patients with advanced malignant and non-malignant disease. Results: A total of 88 patients were studied, primary diagnosis included; chronic obstructive pulmonary disease = 53, interstitial lung disease = 17, cancer = 18. Median (range) London Chest Activities of Daily Living Scale total score was 46.5 (14–67). No floor or ceiling effect was observed for the London Chest Activities of Daily Living Scale total score. Internal consistency was good, and Cronbach’s alpha for the London Chest Activities of Daily Living Scale total score was 0.90. Construct validity was good with 13 out of 15 a priori hypotheses met. Conclusion: Psychometric analyses suggest that the London Chest Activities of Daily Living Scale is acceptable, reliable and valid in patients with advanced disease and refractory breathlessness.

Systems immunology leverages recent technological advancements that enable broad profiling of the immune system to better understand the response to infection and vaccination, as well as the dysregulation that occurs in disease. An increasingly common approach to gain insights from these large-scale profiling experiments involves the application of statistical learning methods to predict disease states or the immune response to perturbations. However, the goal of many systems studies is not to maximize accuracy, but rather to gain biological insights. The predictors identified using current approaches can be biologically uninterpretable or present only one of many equally predictive models, leading to a narrow understanding of the underlying biology. Here we show that incorporating prior biological knowledge within a logistic modeling framework by using network-level constraints on transcriptional profiling data significantly improves interpretability. Moreover, incorporating different types of biological knowledge produces models that highlight distinct aspects of the underlying biology, while maintaining predictive accuracy. We propose a new framework, Logistic Multiple Network-constrained Regression (LogMiNeR), and apply it to understand the mechanisms underlying differential responses to influenza vaccination. Although standard logistic regression approaches were predictive, they were minimally interpretable. Incorporating prior knowledge using LogMiNeR led to models that were equally predictive yet highly interpretable. In this context, B cell-specific genes and mTOR signaling were associated with an effective vaccination response in young adults. Overall, our results demonstrate a new paradigm for analyzing high-dimensional immune profiling data in which multiple networks encoding prior knowledge are incorporated to improve model interpretability.

Health literacy (HL) has been associated with lower mortality in heart failure (HF). However, the results of previous studies may not be generalizable because the research was conducted in relatively young and highly-educated patients in United States settings. This study assessed the association of HL with disease knowledge, self-care, and all-cause mortality among very old patients, with a very low educational level. This prospective study was performed in 556 patients (mean age, 85 years), with high comorbidity, admitted for HF to the geriatric acute-care unit of 6 hospitals in Spain. About 74% of patients had less than primary education and 71% had preserved systolic function. Health literacy was assessed with the Short Assessment of Health Literacy for Spanish-speaking Adults questionnaire, knowledge of HF with the DeWalt questionnaire, and HF self-care with the European Heart Failure Self-Care Behaviour Scale. Disease knowledge progressively increased with HL; compared with being in the lowest (worse) tertile of HL, the multivariable beta coefficient (95%CI) of the HF knowledge score was 0.60 (0.01-1.19) in the second tertile and 0.87 (0.24-1.50) in the highest tertile, P-trend = .008. However, no association was found between HL and HF self-care. During the 12 months of follow-up, there were 189 deaths. Compared with being in the lowest tertile of HL, the multivariable HR (95%CI) of mortality was 0.84 (0.56-1.27) in the second tertile and 0.99 (0.65-1.51) in the highest tertile, P-trend = .969. No association was found between HL and 12-month mortality. This could be partly due to the lack of a link between HL and self-care. Copyright © 2017 Sociedad Española de Cardiología.

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

This paper describes a paper and pencil questionnaire that measures heart disease risk knowledge in people with diabetes. The Heart Disease Fact Questionnaire (HDFQ) is a 25-item questionnaire that was developed to tap into respondents' knowledge of major risk factors for the development of CHD. Approximately half of these items specifically address diabetes-related CHD risk factors. Based on extensive pilot data, the current study analyzed responses from 524 people with diabetes to assess the psychometric properties. The HDFQ is readable to an average 13-year old and imposes little burden. It shows good content and face validity. It demonstrates adequate internal consistency, with Kuder-Richardson-20 formula = 0.77 and good item-total correlations. Item analysis showed a desirable range in P-values. In discriminant function analyses, HDFQ scores differentiated respondents by knowledge of their own cardiovascular health, use of lipid lowering medications, health insurance status, and educational attainment, thus indicating good criterion related validity. This measure of heart disease risk knowledge is brief, understandable to respondents, and easy to administer and score. Its potential for use in research and practice is discussed. Future research should establish norms as well as investigate its test-retest reliability and predictive validity.
Mildew-Omics: How Global Analyses Aid the Understanding of Life and Evolution of Powdery Mildews
Bindschedler, Laurence V.; Panstruga, Ralph; Spanu, Pietro D.
2016-01-01
The common powdery mildew plant diseases are caused by ascomycete fungi of the order Erysiphales. Their characteristic life style as obligate biotrophs renders functional analyses in these species challenging, mainly because of experimental constraints to genetic manipulation. Global large-scale (“-omics”) approaches are thus particularly valuable and insightful for the characterisation of the life and evolution of powdery mildews. Here we review the knowledge obtained so far from genomic, transcriptomic and proteomic studies in these fungi. We consider current limitations and challenges regarding these surveys and provide an outlook on desired future investigations on the basis of the various –omics technologies. PMID:26913042

Smith-Lemli-Opitz syndrome, a congenital and developmental malformation disease, is typified by abnormal accumulation of 7-dehydrocholesterol (7DHC), the immediate precursor of cholesterol (CHOL), and depletion thereof. Knowledge of the effect of 7DHC on the biological membrane is, however, still fragmentary. In this study, large-scale atomistic molecular dynamics simulations, employing two distinct force fields, have been conducted to elucidate differences in the structural properties of a hydrated dimyristoylphosphatidylcholine bilayer due to CHOL and 7DHC. The present series of results indicate that CHOL and 7DHC possess virtually the same ability to condense and order membranes. Furthermore, the condensing and ordering effects are shown to be strengthened at increasing sterol concentrations.

RNA-binding proteins (RBPs) are key players in the post-transcriptional regulation of gene expression. Precise knowledge about their binding sites is therefore critical to unravel their molecular function and to understand their role in development and disease. Individual-nucleotide resolution UV crosslinking and immunoprecipitation (iCLIP) identifies protein–RNA crosslink sites on a genome-wide scale. The high resolution and specificity of this method are achieved by an intramolecular cDNA circularization step that enables analysis of cDNAs that truncated at the protein–RNA crosslink sites.

Importance The heterogeneity of rate of clinical progression among patients with Alzheimer disease leads to difficulty in providing clinical counseling and diminishes the power of clinical trials using disease-modifying agents. Objective To gain a better understanding of the factors that affect the natural history of progression in Alzheimer disease for the purpose of improving both clinical care and clinical trial design. Design, Setting, and Participants A longitudinal cohort study of aging from 2005 to 2014 in the National Alzheimer Coordinating Center. Clinical evaluation of the participants was conducted in 31 National Institute on Aging’s Alzheimer Disease Centers. Nine hundred eighty-four participants in the National Alzheimer Coordinating Center cohort study who died and underwent autopsy and met inclusion and exclusion criteria. Main Outcomes and Measures We sought to model the possibility that knowledge of neurofibrillary tangle burden in the presence of moderate or frequent plaques would add to the ability to predict clinical rate of progression during the ensuing 2 to 3 years. We examined the National Alzheimer Coordinating Center autopsy data to evaluate the effect of different neurofibrillary tangle stages on the rates of progression on several standard clinical instruments: the Clinical Dementia Rating Scale sum of boxes, a verbal memory test (logical memory), and a controlled oral word association task (vegetable naming), implementing a reverse-time longitudinal modeling approach in conjunction with latent class estimation to adjust for unmeasured sources of heterogeneity. Results Several correlations between clinical variables and neurocognitive performance suggest a basis for heterogeneity: Higher education level was associated with lower Clinical Dementia Rating Scale sum of boxes (β = −0.19; P < .001), and frequent vs moderate neuritic plaques were associated with higher Clinical Dementia Rating Scale sum of boxes (β = 1.64; P < .001) and lower logical memory score (β = −1.07; P = .005). The rate of change of the clinical and cognitive scores varied depending on Braak stage, when adjusting for plaques, age of death, sex, education, and APOE genotype. For example, comparing high vs low Braak stage with other variables fixed, the logical memory score decreased a substantial 0.38 additional units per year (95% CI, −0.70 to −0.06; P = .02). Using these data, we estimate that a 300-participant clinical trial with end point of a 20% improvement in slope in rate of change of Clinical Dementia Rating Scale sum of boxes has 89% power when all participants in the trial are from the high Braak stage, compared with 29% power if Braak stage had not used for eligibility. Conclusions and Relevance We found that knowledge of neurofibrillary tangle stage, modeled as the sort of information that could be available from tau positron-emission tomography scans and its use to determine eligibility to a trial, could dramatically improve the power of clinical trials and equivalently reduce the required sample sizes of clinical trials.

ABSTRACT Background: In the Caribbean, mosquito-borne diseases are a public health threat. In Sint Eustatius, dengue, Chikungunya and Zika are now endemic. To control and prevent mosquito-borne diseases, the Sint Eustatius Public Health Department relies on the community to assist with the control of Aedes aegypti mosquito. Unfortunately, community based interventions are not always simple, as community perceptions and responses shape actions and influence behavioural responses Objective: The aim of this study was to determine how the Sint Eustatius population perceives the Aedes aegypti mosquito, mosquito-borne diseases and prevention and control measures and hypothesized that increased knowledge of the virus, vector, control and prevention should result in a lower AQ1 prevalence and incidence of mosquito-borne diseases. Methods: This study was conducted in Sint Eustatius island in the Eastern Caribbean. We combined qualitative and quantitative designs. We conducted interviews and focus groups discussions among community member and health professional in 2013 and 2015. We also conducted cross-sectional survey to assess local knowledge on the vector, virus, and control and prevention. Results: The population is knowledgeable; ©however, mosquito-borne diseases are not the highest health priority. While local knowledge is sometimes put into action, it happens on the 20 household/individual level as opposed to the community level. After the 2014 CHIK outbreak, there was an increase in knowledge about mosquito control and mosquito-borne diseases. Discussion: In the context of Sint Eustatius, when controlling the Aedes population it may be a strategic option to focus on the household level rather than the community and build collaborations with households by supporting them when they actively practice mosquito 25 control. To further increase the level of knowledge on the significance of mosquito-borne diseases, it may also be an option to contextualize the issue of the virus, vector, prevention and control into a broader context. Conclusion: As evidenced by the increasing number of mosquito-borne diseases on the island, it appears that knowledge amongst the lay community may not be transferred into 30 action. This may be attributed to the perception of the Sint Eustatius populations that mosquitoes and the viruses they carry are not a high priority in comparison to other health concerns. PMID:28766466

Autonomic symptoms and sleep disorders are common non-motor symptoms of Parkinson disease (PD), which are correlated with poor quality of life for patients. To assess the frequency of autonomic symptoms in a consecutive series of PD patients and to correlate them with other motor and non-motor symptoms. All consecutive non-demented PD patients who underwent an extensive evaluation including Hoehn and Yahr staging, Unified Parkinson's Disease Rating Scale, Beck's Depression Inventory, Neuropsychiatric Inventory, PDQ-39 Scale, the Parkinson's diseases Sleep Scale, the Epworth Sleepiness Scale and SCOPA-AUT scale were enrolled. Comorbidity has been also considered. Supine to standing position blood pressure and cardiac frequency changes were also measured. 135 PD patients were included (mean age at interview 67.7; mean disease duration: 5.3 years). Patients were stratified according to mean SCOPA-AUT scale score (13.1). Those with higher SCOPA-AUT scale score were significantly older, had longer disease duration, worse disease stage, worse quality of sleep, were more severely affected, and were also taking a higher dosage of levodopa. At multivariate analysis, older age, longer disease duration, and worse quality of sleep were independently associated with higher SCOPA-AUT scale scores. Our results remark the role of autonomic symptoms in PD. In our patient population, characterized by mild to moderate disease severity, most of the patients complained of autonomic nervous system involvement (84%). A significant association between autonomic symptoms and sleep disorders was also observed.

The purpose of the study was to examine received and expected knowledge of patients with knee/hip arthroplasty in seven European countries. The goal was to obtain information for developing empowering patient education. The data were collected (during 2009-2012) from patients (n = 943) with hip/knee arthroplasty prior to scheduled preoperative education and before discharge with the Received Knowledge of hospital patient scale (RKhp) and Expected Knowledge of hospital patient scale (EKhp). Patients' knowledge expectations were high but the level of received knowledge did not correspond to expectations. The difference between received and expected knowledge was higher in Greece and Sweden compared with Finland (p < .0001, p < .0001), Spain (p < .0001, p = .001), and Lithuania (p = .005, p = .003), respectively. Patients' knowledge expectations are important in tailoring patient education. To achieve high standards in the future, scientific research collaboration on empowering patient education is needed between European countries. © The Author(s) 2014.
Role of genomics in cardiovascular medicine

2010-01-01
As all branches of science grow and new experimental techniques become readily accessible, our knowledge of medicine is likely to increase exponentially in the coming years. Recently developed technologies have revolutionized our analytical capacities, leading to vast knowledge of many genes or genomic regions involved in the pathogenesis of congenital heart diseases, which are often associated with other genetic syndromes, coronary artery disease and non-ischemic cardiomyopathies and channelopathies. The knowledge-base of the genesis of cardiovascular diseases is likely going to be further revolutionized in this new era of genomic medicine. Here, we review the advances that have been made over the last several years in this field and discuss different genetic mechanisms that have been shown to underlie a variety of cardiovascular diseases.

Background: India may face a danger of immediate spread of Ebola Virus Disease (EVD) if it enters the subcontinent. Preparedness for such a condition is a part of its prevention. Dentists form a sizeable chunk of healthcare in India and may help in augmenting the health care team at the time of such outbreaks. This paper details the development and evaluation of a specially tailored program for dental students and faculty for imparting knowledge on EVD and its prevention strategies. Aim: To assess the knowledge score for EVD and its prevention after attending a specially tailored program. Materials and Methods: A multidisciplinary team was selected for content development and providing an insight on the topic. The program was attended by students and faculty members of Manav Rachna Dental College. The knowledge of the attendees about EVD was assessed at the end of the program through a structured questionnaire. The response rate was 96%. Result: According to the knowledge score attained, 52.4% of the participant had good knowledge level and 2.8% had poor knowledge level. There was no significant difference in knowledge scores between the participants having prior knowledge and those having no previous knowledge about the disease (p = 0.135). Conclusion: High response rate and good knowledge level attained by most of the participants established evidence of a successful program. PMID:25954650

Heart disease is the leading cause of death for African-American women in the United States. Although African-American women experience higher rates of heart disease with earlier onset and more severe consequences than White women do, they are not aware of their risk for the disease. The Health Belief Model (HBM) has been commonly used to guide preventive interventions in cardiovascular health. However, the HBM has not been evaluated for African-American women regarding its effectiveness. This study explored the perceptions of susceptibility and seriousness of heart disease, and the relationships between socioeconomic status (SES), age, and knowledge of heart disease and its risk factors among 194 educated African-American women from the southern United States. Participants did not perceive themselves to be at high risk for developing heart disease while perceiving heart disease as serious. African-American women who were older perceived heart disease to be more serious than their younger counterparts did. Older women and those with higher SES knew more about heart disease and risk factors. Neither SES nor age moderated the relationship between knowledge and perceived susceptibility or seriousness.

This preliminary study explored peer conflict resolution knowledge in children with and without language impairment (LI). Specifically, it evaluated the utility of a visual analogue scale (VAS) for measuring nuances in such knowledge. Children aged 9-12 years, 26 with typically developing language (TLD) and 6 with LI, completed a training protocol and hypothetical task in which they rated goals and strategies that could be pursued following peer conflict. Whereas participants with TLD provided graded judgments using the entire VAS, most children with LI relied solely on the scale anchors. These results suggest at least two possibilities. The less differentiated manner in which participants with LI utilized the VAS may have been influenced by how they viewed the peer conflict situations. Alternatively, additional training may be required to enable them to consistently use the whole scale. Further research is needed to establish whether ratings made by children with LI reflect differences in social perceptions or a need for further experience with the VAS. In either case, distinguishing between these alternatives will likely provide a better understanding of factors that impact the peer relationships of children with LI. Readers will be able to: (1) identify challenges associated with assessing peer conflict resolution knowledge in children with language impairments; (2) describe current methods for measuring children's peer conflict resolution knowledge; (3) describe a visual analogue rating (VAS) scale and explain the potential advantages of this scale format; and (4) describe similarities and differences in how children with and without LI used a VAS in a hypothetical peer conflict resolution task.

Since the population of adults with congenital heart disease (CHD) is growing, the role of nurse specialists is expanding. In order to advance ACHD nursing, the establishment of an international nursing research agenda is recommended. We aimed to investigate research priorities as perceived by nurse specialists and researchers in ACHD. We applied a sequential quan-qual design. In the quantitative phase, a two-round Delphi study was conducted, in which 37 nurse specialists and nurse researchers in ACHD care participated. Respondents assessed the level of priority of 21 research topics using a 9-point rating scale (1 = no priority at all; 9 = very high priority). In the qualitative phase, semi-structured interviews were performed with six selected Delphi panelists, to scrutinize pending research questions. This study revealed that priority should be given to studies investigating knowledge and education of patients, outcomes of Advanced Practice Nursing, quality of life, transfer and transition, and illness experiences and psychosocial issues in adults with CHD. A low priority was given to post-operative pain, sexual functioning, transplantation in ACHD, and health care costs and utilization. Agreement about the level of priority was obtained for 14 out of 21 research topics. Based on this study, we could develop an international research agenda for ACHD. Researchers ought to focus on these areas of highest priority, in order to expand and strengthen the body of knowledge in ACHD nursing.

Objective Critical congenital heart disease (CCHD) is a leading cause of death in infants. Newborn screening (NBS) by pulse oximetry allows early identification of CCHD in asymptomatic newborns. To improve readiness of hospital neonatal birthing facilities for mandatory screening in Texas, an educational and quality improvement (QI) project was piloted to identify an implementation strategy for CCHD NBS in a range of birthing hospitals. Study Design Thirteen Texas hospitals implemented standardized CCHD screening by pulse oximetry. An educational program was devised and a tool kit was created to facilitate education and implementation. Newborn nursery nurses' knowledge was assessed using a pre- and posttest instrument. Results The nurses' knowledge assessment improved from 71 to 92.5% ( p < 0.0001). Of 11,322 asymptomatic newborns screened after 24 hours of age, 11 had a positive screen, with 1 confirmed case of CCHD. Pulse oximetry CCHD NBS had sensitivity of 100%, specificity of 99.91%, false-positive rate of 0.088%, positive predictive value of 9.09%, and negative predictive value of 100%. Conclusion Our educational program, including a tool kit, QI processes, and standardized pulse oximetry CCHD NBS, is applicable for a range of hospital birthing facilities and may facilitate wide-scale implementation, thereby improving newborn health.

The incidence of inflammatory bowel diseases (IBD) - Crohn’s disease (CD) and ulcerative colitis (UC) - has been increasing on a global scale, and progressively, more gastroenterologists will be included in the diagnosis and treatment of IBD. Although IBD primarily affects the intestinal tract, extraintestinal manifestations of the disease are often apparent, including in the oral cavity, especially in CD. Specific oral manifestations in patients with CD are as follows: indurate mucosal tags, cobblestoning and mucogingivitis, deep linear ulcerations and lip swelling with vertical fissures. The most common non-specific manifestations, such as aphthous stomatitis and angular cheilitis, occur in both diseases, while pyostomatitis vegetans is more pronounced in patients with UC. Non-specific lesions in the oral cavity can also be the result of malnutrition and drugs. Malnutrition, followed by anemia and mineral and vitamin deficiency, affects the oral cavity and teeth. Furthermore, all of the drug classes that are applied to the treatment of inflammatory bowel diseases can lead to alterations in the oral cavity due to the direct toxic effects of the drugs on oral tissues, as well as indirect immunosuppressive effects with a risk of developing opportunistic infections or bone marrow suppression. There is a higher occurrence of malignant diseases in patients with IBD, which is related to the disease itself and to the IBD-related therapy with a possible oral pathology. Treatment of oral lesions includes treatment of the alterations in the oral cavity according to the etiology together with treatment of the primary intestinal disease, which requires adequate knowledge and a strong cooperation between gastroenterologists and specialists in oral medicine.

Differing perceptions - Swedish farmers' views of infectious disease control.
Frössling, Jenny; Nöremark, Maria
2016-02-01
Although farm biosecurity reduces the risk of disease spread among livestock, this knowledge is not always applied. Farmers' application of disease preventive measures is expected to depend on many things, e.g. whether they consider disease prevention possible and demographic factors. In this study, Swedish livestock farmers' perspectives on occurrence, control and communication related to infectious livestock diseases were investigated. A questionnaire study was performed in 2012-2013, and included responses from almost 2000 livestock farmers with cattle, pigs, sheep or goats. Associations between responses and factors related to herd type and demography were investigated using multivariable regression models. Results showed a strong general agreement among farmers that disease prevention is important. However, results also showed differing opinions among farmers. For example, female farmers indicated higher levels of perceived knowledge of disease spread and a stronger belief that they can prevent disease introduction. Results indicate that farmers who believe they have the necessary knowledge, have stronger sense of control and also demand that others take responsibility to prevent spread. Furthermore, dairy farmers were more likely to respond that repeated exposure to infections could be beneficial for animal health. The number of perceived disease outbreaks was also higher among these farmers. Regarding government issued compensation to farmers in case of outbreaks, a wide range of opinions were recorded. Responses confirm that the farm veterinarian is an important source of disease information and several different communication channels are needed to reach farmers. In conclusion, our results show that factors such as gender, education level and age influence how prevention and occurrence of disease outbreaks are perceived and best communicated. We suggest that efforts are made to increase knowledge about disease prevention among farmers and veterinary practitioners and that farm veterinarians should be encouraged to motivate farmers to strengthen farm biosecurity.
The biomedical disciplines and the structure of biomedical and clinical knowledge.
Nederbragt, H
2000-11-01
The relation between biomedical knowledge and clinical knowledge is discussed by comparing their respective structures. The knowledge of a disease as a biological phenomenon is constructed by the interaction of facts and theories from the main biomedical disciplines: epidemiology, diagnostics, clinical trial, therapy development and pathogenesis. Although these facts and theories are based on probabilities and extrapolations, the interaction provides a reliable and coherent structure, comparable to a Kuhnian paradigma. In the structure of clinical knowledge, i.e. knowledge of the patient with the disease, not only biomedical knowledge contributes to the structure but also economic and social relations, ethics and personal experience. However, the interaction between each of the participating "knowledges" in clinical knowledge is not based on mutual dependency and accumulation of different arguments from each, as in biomedical knowledge, but on competition and partial exclusion. Therefore, the structure of biomedical knowledge is different from that of clinical knowledge. This difference is used as the basis for a discussion in which the place of technology, evidence-based medicine and the gap between scientific and clinical knowledge are evaluated.
‘A Most Protean Disease’: Aligning Medical Knowledge of Modern Influenza, 1890–1914
Bresalier, Michael
2012-01-01
This article reconstructs the process of defining influenza as an infectious disease in the contexts of British medicine between 1890 and 1914. It shows how professional agreement on its nature and identity involved aligning different forms of knowledge produced in the field (public health), in the clinic (metropolitan hospitals) and in the laboratory (bacteriology). Two factors were crucial to this process: increasing trust in bacteriology and the organisation of large-scale collective investigations into influenza by Britain’s central public authority, the Medical Department of the Local Government Board. These investigations integrated epidemiological, clinical and bacteriological evidence into a new definition of influenza as a specific infection, in which a germ – Bacillus influenzae – was determined as playing a necessary but not sufficient role in its aetiology, transmission and pathogenesis. In defining ‘modern influenza’, bacteriological concepts and techniques were adapted to and selectively incorporated into existing clinical, pathological and epidemiological approaches. Mutual alignment thus was crucial to its construction and, more generally, to shaping developing relationships between laboratory, clinical and public health medicine in turn-of-the-century Britain. While these relationships were marked by tension and conflict, they were also characterised by important patterns of convergence, in which the problems, interests and practices of public health professionals, clinicians and laboratory pathologists were made increasingly commensurable. Rather than retrospectively judge the late nineteenth-century definition of influenza as being based on the wrong microbe, this article argues for the need to examine how it was established through a particular alignment of medical knowledge, which then underpinned medical approaches to the disease up to and beyond the devastating 1918–19 pandemic.

Prevention providers wonder whether benefits achieved in the original, researcher-led, efficacy trials of interventions are replicated when the intervention is delivered in real-world settings by their agency's staff. A replication study was conducted at 2 public sexually transmitted disease (STD) clinics (New York City and San Juan, PR). Using a controlled trial design, intervention (VOICES/VOCES) and comparison conditions (regular clinic services) were assigned in alternating 4-week blocks. Trained agency staff delivered the intervention. Effectiveness was assessed for incident STDs, redemption of coupons for condoms at neighborhood location after the visit, and improved knowledge and attitudes about STDs and condoms. A total of 3365 patients were recruited, completed the protocol, and followed through STD surveillance systems for an average of 17 months. Of 397 with an incident infection, 226 (13.4%) were among those enrolled during comparison blocks; 171 were among those in the intervention condition (10.2%). Controlling for site and gender, participants enrolled during intervention blocks were significantly less likely to have an incident STD reported to the surveillance system (hazard ratio, 0.78; 95% confidence interval, 0.64-0.96). Intervention block participants scored higher on scales of STD knowledge (4.89 vs. 3.87, P < 0.001) and condom knowledge, attitude, and efficacy (10.98 vs. 9.16, P < 0.001). More of those exposed to VOICES/VOCES redeemed condoms (P < 0.05). Positive effects were more consistent in New York, which may be related to fidelity of implementation. A packaged human immunodeficiency virus prevention intervention can be delivered by agencies, with benefits similar to those achieved in the research setting.
Scale invariant texture descriptors for classifying celiac disease
Hegenbart, Sebastian; Uhl, Andreas; Vécsei, Andreas; Wimmer, Georg
2013-01-01
Scale invariant texture recognition methods are applied for the computer assisted diagnosis of celiac disease. In particular, emphasis is given to techniques enhancing the scale invariance of multi-scale and multi-orientation wavelet transforms and methods based on fractal analysis. After fine-tuning to specific properties of our celiac disease imagery database, which consists of endoscopic images of the duodenum, some scale invariant (and often even viewpoint invariant) methods provide classification results improving the current state of the art. However, not each of the investigated scale invariant methods is applicable successfully to our dataset. Therefore, the scale invariance of the employed approaches is explicitly assessed and it is found that many of the analyzed methods are not as scale invariant as they theoretically should be. Results imply that scale invariance is not a key-feature required for successful classification of our celiac disease dataset. PMID:23481171
