Simple Summary This paper provides insight into the role of farm animals in farm-based programs and their importance to different types of participants. Farm animals provide real work, close relationships, challenging tasks and opportunities for reflection. They also contribute to a welcoming atmosphere for various types of participants. Abstract We explore the role of farm animals in providing care to different types of participants at care farms (e.g., youngsters with behavioural problems, people with severe mental problems and people with dementia). Care farms provide alternative and promising settings where people can interact with animals compared to a therapeutic healthcare setting. We performed a literature review, conducted focus group meetings and carried out secondary data-analysis of qualitative studies involving care farmers and different types of participants. We found that farm animals are important to many participants and have a large number of potential benefits. They can (i) provide meaningful day occupation; (ii) generate valued relationships; (iii) help people master tasks; (iv) provide opportunities for reciprocity; (v) can distract people from them problems; (vi) provide relaxation; (vii) facilitate customized care; (viii) facilitate relationships with other people; (ix) stimulate healthy behavior; (x) contribute to a welcoming environment; (xi) make it possible to experience basic elements of life; and (xii) provide opportunities for reflection and feedback. This shows the multi-facetted importance of interacting with animals on care farms. In this study the types of activities with animals and their value to different types of participants varied. Farm animals are an important element of the care farm environment that can address the care needs of different types of participants. PMID:28574435

Membership in important social groups can promote a positive identity. We propose and test an identity resource model in which personal self-esteem is boosted by membership in additional important social groups. Belonging to multiple important group memberships predicts personal self-esteem in children (Study 1a), older adults (Study 1b), and former residents of a homeless shelter (Study 1c). Study 2 shows that the effects of multiple important group memberships on personal self-esteem are not reducible to number of interpersonal ties. Studies 3a and 3b provide longitudinal evidence that multiple important group memberships predict personal self-esteem over time. Studies 4 and 5 show that collective self-esteem mediates this effect, suggesting that membership in multiple important groups boosts personal self-esteem because people take pride in, and derive meaning from, important group memberships. Discussion focuses on when and why important group memberships act as a social resource that fuels personal self-esteem. PMID:26017554

The relationship between emission reductions and changes in ozone can be studied using photochemical grid models. These models are updated with new information as it becomes available. The primary objective of this study was to update the previous Collet et al. studies by using the most up-to-date (at the time the study was done) modeling emission tools, inventories, and meteorology available to conduct ozone source attribution and sensitivity studies. Results show future-year, 2030, design values for 8-hr ozone concentrations were lower than base-year values, 2011. The ozone source attribution results for selected cities showed that boundary conditions were the dominant contributors to ozone concentrations at the western U.S. locations, and were important for many of the eastern U.S. Point sources were generally more important in the eastern United States than in the western United States. The contributions of on-road mobile emissions were less than 5 ppb at a majority of the cities selected for analysis. The higher-order decoupled direct method (HDDM) results showed that in most of the locations selected for analysis, NOx emission reductions were more effective than VOC emission reductions in reducing ozone levels. The source attribution results from this study provide useful information on the important source categories and provide some initial guidance on future emission reduction strategies. The relationship between emission reductions and changes in ozone can be studied using photochemical grid models, which are updated with new available information. This study was to update the previous Collet et al. studies by using the most current, at the time the study was done, models and inventory to conduct ozone source attribution and sensitivity studies. The source attribution results from this study provide useful information on the important source categories and provide some initial guidance on future emission reduction strategies.

Background Attention has been paid to cotinine (COT), one of the major metabolites of nicotine (NIC), for its pro-cognitive effects and potential therapeutic activities against Alzheimer's Disease (AD) and other types of cognitive impairment. In order to facilitate pharmacological and toxicological studies on COT for its pro-cognitive activities, we conducted a pharmacokinetic (PK) study of COT in rats, providing important oral and intravenously (IV) PK information. Methods In this study, plasma samples were obtained up to 48 hours after COT was dosed to rats orally and IV at a dose of 3 mg/kg. Plasma samples were prepared and analyzed using a sensitive liquid chromatography tandem mass spectrometry (LC-MS/MS) bioanalytical method, providing concentration profiles of COT and metabolites after oral and IV administrations. Results The data were fitted into a one-compartment model and a two-compartment model for the oral and IV groups, respectively, providing important PK information for COT including PK profiles, half-life, clearance and bioavailability. The results suggested fast absorption, slow elimination and high bioavailability of COT in rats. Conclusions Several important facts about the PK properties in rats suggested COT could be a potential pro-cognitive agent. Information about the pharmacokinetics of COT in rats revealed in this study is of great importance for the future studies on COT or potential COT analogues as agents for improving cognition.

The mentoring of male and female scientists during their doctoral studies

NASA Astrophysics Data System (ADS)

Filippelli, Laura Ann

The mentoring relationships of male and female scientists during their doctoral studies were examined. Male and female biologists, chemists, engineers and physicists were compared regarding the importance of doctoral students receiving career enhancing and psychosocial mentoring from their doctoral chairperson and student colleagues. Scientists' satisfaction with their chairperson and colleagues as providers of these mentoring functions was also investigated. In addition, scientists identified individuals other than their chairperson and colleagues who were positive influencers on their professional development as scientists and those who hindered their development. A reliable instrument, "The Survey of Accomplished Scientists' Doctoral Experiences," was developed to assess career enhancing and psychosocial mentoring of doctoral chairpersons and student colleagues based on the review of literature, interviews with scientists and two pilot studies. Surveys were mailed to a total of 400 men and women scientists with earned doctorates, of which 209 were completed and returned. The findings reveal that female scientists considered the doctoral chairperson furnishing career enhancing mentoring more important than did the men, while both were in accordance with the importance of them providing psychosocial mentoring. In addition, female scientists were not as satisfied as men with their chairperson providing most of the career enhancing and psychosocial mentoring functions. For doctoral student colleagues, female scientists, when compared to men, indicated that they considered student colleagues more important in providing career enhancing and psychosocial mentoring. However, male and female scientists were equally satisfied with their colleagues as providers of these mentoring functions. Lastly, the majority of male scientists indicated that professors served as a positive influencer, while women revealed that spouses and friends positively influenced their professional development as scientists. Several recommended changes in science departments are provided.

Merluzzi, T V; Martinez Sanchez, M A

1997-09-01

We studied perceptions of the importance and difficulty of coping behaviors, from the perspectives of cancer patients (n = 33) and health care providers (i.e. nursing and technical personnel, n = 24). They rated the importance and difficulty of 43 behaviors that correspond to six domains of coping with cancer. Generally, ratings of importance were similar for both patients and providers. However, patients rated the domains of Coping with Treatment Related Side Effects and Seeking Support as less important than staff. Ratings of difficulty were quite divergent. Patients perceived coping as less difficult than the medical staff in the following domains: Maintenance of Activity and Independence, Coping With Treatment-Related Side-Effects, Accepting Cancer/Maintaining Positive Attitude, and Seeking Support. These differences in difficulty ratings between patients and health care providers may reflect distinct perspectives or schemas about coping. That is, patients may hold 'positive illusions' about their coping capacity and, therefore, rate coping as less difficult. Health care providers may overestimate patients' distress and, therefore, underestimate patients' coping capacity. An understanding of these different perspectives may assist medical staff in fostering self-efficacy expectations for coping behaviors.

Background Historically, effectiveness of community collaborative prevention efforts has been mixed. Consequently, research has been undertaken to better understand the factors that support their effectiveness; theory and some related empirical research suggests that the provision of technical assistance is one important supporting factor. The current study examines one aspect of technical assistance that may be important in supporting coalition effectiveness, the collaborative relationship between the technical assistance provider and site lead implementer. Methods Four and one-half years of data were collected from technical assistance providers and prevention team members from the 14 community prevention teams involved in the PROSPER project. Results Spearman correlation analyses with longitudinal data show that the levels of the collaborative relationship during one phase of collaborative team functioning associated with characteristics of internal team functioning in future phases. Conclusions Results suggest that community collaborative prevention work should consider the collaborative nature of the technical assistance provider – prevention community team relationship when designing and conducting technical assistance activities, and it may be important to continually assess these dynamics to support high quality implementation.

Package inserts (PIs) as a reliable reference for patients and health care providers should provide accurate, complete and up-to-date information. The purpose of the current study is to assess and compare the PIs of antihypertensive agents locally produced in Palestine and their imported counterparts. Thirty-five PIs were assessed for the presence of 31 information statements using a scoring method. Word counting of 20 headings and subheadings was used to evaluate and compare local and imported PIs for information quantity. None of the analysed PIs fulfilled the criteria. All of them included the brand name, active ingredients, indications, directions for use, adverse drug reactions, drug-drug interactions, pregnancy and lactation considerations, and storage. Whereas none of them, either local or imported PIs, included the shelf life and instructions to convert tablets or capsules into liquid forms. Additionally, only one (5%) imported and no (0%) local PIs mentioned the duration of therapy. Moreover, 93.4% of local PIs were deficient in areas regarding the inactive ingredients and date of last revision, and 86.7% did not mention the drug dose and possibility of tablet splitting. Furthermore, the maximum dose was not indicated in 90% of imported and 86.7% of local PIs. In general, imported PIs contained more detailed information than their local counterparts, where the range of differences in medians between the local and imported PIs was from 1.5-fold for pregnancy considerations to >42.00-fold for the effect on the ability to drive and use machines. The findings of this study revealed the superiority of imported over local PIs in both quality and quantity of information provided. This emphasises the need for appropriate measures to be taken by the Ministry of Health and local manufacturers to ensure efficiency of local PIs in providing accurate, complete and up-to-date information.

This case study provides a mid-course assessment of the Bronx Health REACH faith-based initiative four years into its implementation. The study uses qualitative methods to identify lessons learned and to reflect on the benefits and challenges of using a community-based participatory approach for the development and evaluation of a faith-based program designed to address health disparities. Key findings concern the role of pastoral leadership, the importance of providing a religious context for health promotion and health equality messages, the challenges of creating a bilingual/bi-cultural program, and the need to provide management support to the lay program coordinators. The study also identifies lessons learned about community-based evaluation and the importance of addressing community concern about the balance between evaluation and program. Finally, the study identifies the challenges that lie ahead, including issues of program institution-alization and sustainability. PMID:20168022

Zhang, S.; Toll, J.; Cothern, K.

1995-12-31

The authors have performed robust sensitivity studies of the physico-chemical Hudson River PCB model PCHEPM to identify the parameters and process uncertainties contributing the most to uncertainty in predictions of water column and sediment PCB concentrations, over the time period 1977--1991 in one segment of the lower Hudson River. The term ``robust sensitivity studies`` refers to the use of several sensitivity analysis techniques to obtain a more accurate depiction of the relative importance of different sources of uncertainty. Local sensitivity analysis provided data on the sensitivity of PCB concentration estimates to small perturbations in nominal parameter values. Range sensitivity analysismore » provided information about the magnitude of prediction uncertainty associated with each input uncertainty. Rank correlation analysis indicated which parameters had the most dominant influence on model predictions. Factorial analysis identified important interactions among model parameters. Finally, term analysis looked at the aggregate influence of combinations of parameters representing physico-chemical processes. The authors scored the results of the local and range sensitivity and rank correlation analyses. The authors considered parameters that scored high on two of the three analyses to be important contributors to PCB concentration prediction uncertainty, and treated them probabilistically in simulations. They also treated probabilistically parameters identified in the factorial analysis as interacting with important parameters. The authors used the term analysis to better understand how uncertain parameters were influencing the PCB concentration predictions. The importance analysis allowed us to reduce the number of parameters to be modeled probabilistically from 16 to 5. This reduced the computational complexity of Monte Carlo simulations, and more importantly, provided a more lucid depiction of prediction uncertainty and its causes.« less

Analysing farmer knowledge of the requirements of finance providers can provide valuable insights to policy makers about ways to improve farmers' access to finance. This study compares farmer knowledge of the requirements to obtain finance with the actual requirements set by different finance provider types, and investigates the relation between demographic and socioeconomic factors and farmer knowledge of finance requirements. We use a structured questionnaire to collect data from a sample of finance providers and farmers in Java Island, Indonesia. We find that the most important requirements to acquire finance vary among different finance provider types. We also find that farmers generally have little knowledge of the requirements, which are important to each type of finance provider. Awareness campaigns are needed to increase farmer knowledge of the diversity of requirements among the finance provider types.

Organellar proteomics reveals hundreds of novel nuclear proteins in the malaria parasite Plasmodium falciparum

PubMed Central

2012-01-01

Background The post-genomic era of malaria research provided unprecedented insights into the biology of Plasmodium parasites. Due to the large evolutionary distance to model eukaryotes, however, we lack a profound understanding of many processes in Plasmodium biology. One example is the cell nucleus, which controls the parasite genome in a development- and cell cycle-specific manner through mostly unknown mechanisms. To study this important organelle in detail, we conducted an integrative analysis of the P. falciparum nuclear proteome. Results We combined high accuracy mass spectrometry and bioinformatic approaches to present for the first time an experimentally determined core nuclear proteome for P. falciparum. Besides a large number of factors implicated in known nuclear processes, one-third of all detected proteins carry no functional annotation, including many phylum- or genus-specific factors. Importantly, extensive experimental validation using 30 transgenic cell lines confirmed the high specificity of this inventory, and revealed distinct nuclear localization patterns of hitherto uncharacterized proteins. Further, our detailed analysis identified novel protein domains potentially implicated in gene transcription pathways, and sheds important new light on nuclear compartments and processes including regulatory complexes, the nucleolus, nuclear pores, and nuclear import pathways. Conclusion Our study provides comprehensive new insight into the biology of the Plasmodium nucleus and will serve as an important platform for dissecting general and parasite-specific nuclear processes in malaria parasites. Moreover, as the first nuclear proteome characterized in any protist organism, it will provide an important resource for studying evolutionary aspects of nuclear biology. PMID:23181666

The influence of loan repayment on rural healthcare provider recruitment and retention in Colorado.

Renner, Daniel M; Westfall, John M; Wilroy, Lou Ann; Ginde, Adit A

2010-01-01

There is an ongoing shortage of rural healthcare providers relative to urban healthcare providers worldwide. Many strategies have been implemented to increase the distribution of rural healthcare providers, and financial incentives such as loan repayment programs have become popular means to both recruit and retain healthcare providers in rural communities. Studies detailing the effects of such programs on rural provider recruitment and retention are limited. The objective of this study was to assess the influence of loan repayment and other factors on the recruitment and retention of healthcare providers in rural Colorado, USA, and to compare the motivations and attitudes of these rural providers with their urban counterparts. A survey was sent to 122 healthcare providers who had participated in one of three loan repayment programs in Colorado between the years of 1992 and 2007: the Colorado Health Professional Loan Repayment Program; the Colorado Rural Outreach Program; and the Dental Loan Repayment Program of Colorado. Differentiation between rural and urban communities was accomplished by using the Rural Urban Commuting Area Codes developed by the University of Washington's Rural Health Research Center and Economic Research Service. Statistical analysis was performed using STATA from StataCorp. Of the 93 respondents included in the study, 57 worked in rural communities and 36 worked in urban communities during their programs. Of the rural participants, 74% were already working in or intending to work in an eligible community when they were made aware of the loan repayment program. Of those planning to work in a rural community regardless of any loan repayment option, 42% reported that the loan repayment program had an important influence on the specific community in which they chose to practice. Of the rural participants already working in a rural community, 38% reported loan repayment as being an important factor in their retention. The most important factors the rural providers cited for their recruitment were the location of the community, scope of practice, and family fit with the community. The most important factors for the urban providers were the location of the community, salary, and scope of practice. Of the rural providers, 36% attended rural high schools, while 9% of urban providers attended rural high schools. Of the rural providers who were planning on practicing in a rural area regardless of any loan repayment option, 37% had attended rural high schools. Rural participants most often left their communities because their families wanted to move, personal or professional isolation, and dissatisfaction with the medical community. Of rural participants 22% cited the desire for a higher income as an important reason to leave their communities, while the desire for a higher income was the most commonly cited reason for the urban providers. Rural retention rates were not influenced by past attendance at rural high schools or by intention to practice in a rural community regardless of loan repayment. Loan repayment programs targeting rural Colorado usually enroll providers who would have worked in a rural area regardless of loan repayment opportunities, but are likely to play a role in providers' choice of specific rural community for practice. They also appear to have a limited but important influence on rural provider retention, though financial concerns are generally less influential for non-retained rural providers than are family preferences and professional dissatisfaction.

Deep X-ray and UV Surveys of Galaxies with Chandra, XMM-Newton, and GALEX

NASA Technical Reports Server (NTRS)

Hornschemeier, Ann

2006-01-01

Only with the deepest Chandra surveys has X-ray emission from normal and star forming galaxies (as opposed to AGN, which dominate the X-ray sky) been accessible at cosmologically interesting distances. The X-ray emission from accreting binaries provide a critical glimpse into the binary phase of stellar evolution and studies of the hot gas reservoir constrain past star formation. UV studies provide important, sensitive diagnostics of the young star forming populations and provide the most mature means for studying galaxies at 2 < zeta < 4. This talk will review current progress on studying X-ray emission in concert with UV emission from normal/star-forming galaxies at higher redshift. We will also report on our new, deep surveys with GALEX and XMM-Newton in the nearby Coma cluster. These studies are relevant to DEEP06 as Coma is the nearest rich cluster of galaxies and provides an important benchmark for high-redshift studies in the X-ray and UV wavebands. The 30 ks GALEX (note: similar depth to the GALEX Deep Imaging Survey) and the 110 ks XMM observations provide extremely deep coverage of a Coma outskirts field, allowing the construction of the UV and X-ray luminosity function of galaxies and important constraints on star formation scaling relations such as the X-ray-Star Formation Rate correlation and the X-ray/Stellar Mass correlation. We will discuss what we learn from these deep observations of Coma, including the recently established suppression of the X-ray emission from galaxies in the Coma outskirts that is likely associated with lower levels of past star formation and/or the results of tidal gas stripping.

2015-03-01

The aim of this study is to find and compare the current situation between common people and healthcare providers' preferences for a good death in the context of Chinese culture. A cross-sectional anonymous questionnaire survey covering 190 ordinary Chinese people and 323 healthcare providers was conducted. An inventory of the good death was translated and the subjects were surveyed about their attitude toward it. Permission to conduct the study was granted by department chiefs, nurse managers and the participants themselves. The participants were informed that they took part on a voluntary and anonymous basis, that they could withdraw at any time, that they had the right to ignore questions they did not wish to answer, and that whatever they chose to do would not jeopardize their employment conditions. The attributes that were perceived as important by major respondents for a good death were maintaining hope and pleasure, good relationship with medical staff, good relationship with family, independence, environment comfort, being respected as an individual, preparation for death, physical and psychological comfort, dying in a favorite place, and not being a burden to others. And some relatively less important characteristics were life completion, receiving enough treatment, natural death, controlling over the future, unawareness of death, pride and beauty, feeling that one's life is worth living, and religious and spiritual comfort. We also found that healthcare providers were more likely than general out-patients to perceive "physical and psychological comfort," "dying in a favorite place," "good relationship with medical staff," and "natural death" as important for a good death. This study offers healthcare providers in China a fundamental understanding of the normal expectations of the general public for a good death. It is believed that these findings in our study are valuable to improve palliative care in China. We compared the attitudes of Chinese and Westerners and found some differences, which suggested that cultural difference should be an important consideration to achieve a good death in China. We also found that healthcare providers see good death differently from general public, indicating that the criteria for good death warrant further study. © The Author(s) 2014.

Weight as an embodiment of importance.

PubMed

Jostmann, Nils B; Lakens, Daniël; Schubert, Thomas W

2009-09-01

Four studies show that the abstract concept of importance is grounded in bodily experiences of weight. Participants provided judgments of importance while they held either a heavy or a light clipboard. Holding a heavy clipboard increased judgments of monetary value (Study 1) and made participants consider fair decision-making procedures to be more important (Study 2). It also caused more elaborate thinking, as indicated by higher consistency between related judgments (Study 3) and by greater polarization of agreement ratings for strong versus weak arguments (Study 4). In line with an embodied perspective on cognition, these findings suggest that, much as weight makes people invest more physical effort in dealing with concrete objects, it also makes people invest more cognitive effort in dealing with abstract issues.

2015-01-01

Controlling the spread of influenza to reduce the effects of infection on a population is an important mandate of public health. Mass media reports on an epidemic or pandemic can provide important information to the public, and in turn, can induce positive healthy behaviour practices (i.e., handwashing, social distancing) in the individuals, that will reduce the probability of contracting the disease. Mass media fatigue, however, can dampen these effects. Mathematical models can be used to study the effects of mass media reports on epidemic/pandemic outcomes. In this study we employ a stochastic agent based model to provide a quantification of mass media reports on the variability in important public health measurements. We also include mass media report data compiled by the Global Public Health Intelligence Network, to study the effects of mass media reports in the 2009 H1N1 pandemic. We find that the report rate and the rate at which individuals relax their healthy behaviours (media fatigue) greatly affect the variability in important public health measurements. When the mass media reporting data is included in the model, two peaks of infection result. PMID:26528909

The rise in consumer-centric health insurance plans has increased the importance of the patient in choosing a provider. There is a paucity of studies that examine how patients select an orthopaedic sports medicine physician. To evaluate factors that patients consider when choosing an orthopaedic sports medicine physician. Case series; Level of evidence, 4. A total of 1077 patients who sought treatment by 3 sports medicine physicians were administered an anonymous questionnaire. The questionnaire included 19 questions asking respondents to rate the importance of specific factors regarding the selection of orthopaedic sports medicine physicians on a scale of 1 (not important at all) to 10 (very important). The remaining 6 questions were multiple-choice and regarded the following criteria: preferred physician age, appointment availability, clinic waiting room times, travel distance, and medical student/resident involvement. Of the 1077 consecutive patients administered the survey, 382 (35%) responded. Of these, 59% (n = 224) were male, and 41% (n = 158) were female. In ranking the 19 criteria in terms of importance, patients rated board certification (9.12 ± 1.88), being well known for a specific area of expertise (8.27 ± 2.39), and in-network provider status (8.13 ± 2.94) as the 3 most important factors in selecting an orthopaedic sports medicine physician. Radio, television, and Internet advertisements were rated the least important. Regarding physician age, 63% of patients would consider seeking a physician who is ≤65 years old. Approximately 78% of patients would consider seeking a different physician if no appointments were available within 4 weeks. The study results suggest that board certification, being well known for a specific area of expertise, and health insurance in-network providers may be the most important factors influencing patient selection of an orthopaedic sports medicine physician. Advertisements were least important to patients. Patient preferences varied regarding ideal physician age, clinic appointment availability, medical student/resident involvement, and travel distance in choosing an orthopaedic sports medicine physician. In the context of health care delivery and as reimbursement becomes increasingly consumer centered, understanding the process of provider selection is important.

Adenosine and Hypoxia-Inducible Factor Signaling in Intestinal Injury and Recovery

PubMed Central

Eltzschig, Holger K.

2013-01-01

The gastrointestinal mucosa has proven to be an interesting tissue in which to investigate disease-related metabolism. In this review, we outline some of the evidence that implicates hypoxia-mediated adenosine signaling as an important signature within both healthy and diseased mucosa. Studies derived from cultured cell systems, animal models, and human patients have revealed that hypoxia is a significant component of the inflammatory microenvironment. These studies have revealed a prominent role for hypoxia-induced factor (HIF) and hypoxia signaling at several steps along the adenine nucleotide metabolism and adenosine receptor signaling pathways. Likewise, studies to date in animal models of intestinal inflammation have demonstrated an almost uniformly beneficial influence of HIF stabilization on disease outcomes. Ongoing studies to define potential similarities with and differences between innate and adaptive immune responses will continue to teach us important lessons about the complexity of the gastrointestinal tract. Such information has provided new insights into disease pathogenesis and, importantly, will provide insights into new therapeutic targets. PMID:21942704

The presence of Brettanomyces bruxellensis is an important issue during winemaking because of its volatile phenols production capacities. The aim of this study is to provide information on the ability of residual B. bruxellensis populations to multiply and spoil finished wines during storage in bottles. Several finished wines were studied. Brettanomyces bruxellensis populations were monitored during two and a half months, and volatile phenols as well as chemical parameters regularly determined. Variable growth and volatile phenols synthesis capacities were evidenced, in particularly when cells are in a noncultivable state. In addition, the volatile phenol production was clearly shown to be a two-step procedure that could strongly be correlated to the physiological state of the yeast population. This study underlines the importance of minimizing B. bruxellensis populations at the end of wine ageing to reduce volatile phenols production risk once the wine in bottle. Moreover, the physiological state of the yeast seems to have an important impact on ethyl-phenols production, hence demonstrating the importance of taking into account this parameter when analysing wine spoilage risks. Little data exist about the survival of B. bruxellensis once the wine in bottle. This study provides information on the alteration risks encountered during wine storage in bottle and reveals the importance of carrying on further studies to increase the knowledge on B. bruxellensis physiology.

The Culture Care theory and the Old Order Amish.

Wenger, A F

1991-11-01

This chapter discussed knowledge about culture care and culture context in relation to Old Order Amish culture. Leininger's theory of Cultural Care Diversity and Universality and Hall's concept of high-context culture were used to study culture care of the Old Order Amish. This study provided new findings about the culture, especially as related to culture care and high context. These findings also are important to guide nurses and other health care professionals in providing culture-specific care to the Old Order Amish. Leininger's Cultural Care theory has provided a comprehensive theoretical framework to explicate embedded care constructs and patterns of daily living within this culture. Hall's concepts helped to value and discover the importance of high context within the Old Order Amish culture and its relation to the phenomenon of care.

Historically, effectiveness of community collaborative prevention efforts has been mixed. Consequently, research has been undertaken to better understand the factors that support their effectiveness; theory and some related empirical research suggests that the provision of technical assistance is one important supporting factor. The current study examines one aspect of technical assistance that may be important in supporting coalition effectiveness, the collaborative relationship between the technical assistance provider and site lead implementer. Four and one-half years of data were collected from technical assistance providers and prevention team members from the 14 community prevention teams involved in the PROSPER project. Spearman correlation analyses with longitudinal data show that the levels of the collaborative relationship during one phase of collaborative team functioning associated with characteristics of internal team functioning in future phases. Results suggest that community collaborative prevention work should consider the collaborative nature of the technical assistance provider - prevention community team relationship when designing and conducting technical assistance activities, and it may be important to continually assess these dynamics to support high quality implementation.

Selecting a provider: what factors influence patients' decision making?

PubMed

Abraham, Jean; Sick, Brian; Anderson, Joseph; Berg, Andrea; Dehmer, Chad; Tufano, Amanda

2011-01-01

Each year consumers make a variety of decisions relating to their healthcare. Some experts argue that stronger consumer engagement in decisions about where to obtain medical care is an important mechanism for improving efficiency in healthcare delivery and financing. Consumers' ability and motivation to become more active decision makers are affected by several factors, including financial incentives and access to information. This study investigates the set of factors that consumers consider when selecting a provider, including attributes of the provider and the care experience and the reputation of the provider. Additionally, the study evaluates consumers awareness and use of formal sources of provider selection information. Our results from analyzing data from a survey of 467 patients at four clinics in Minnesota suggest that the factors considered of greatest importance include reputation of the physician and reputation of the healthcare organization. Contractual and logistical factors also play a role, with respondents highlighting the importance of seeing a provider affiliated with their health plan and appointment availability. Few respondents indicated that advertisements or formal sources of quality information affected their decision making. The key implication for provider organizations is to carefully manage referral sources to ensure that they consistently meet the needs of referrers. Excellent service to existing patients and to the network of referring physicians yields patient and referrer satisfaction that is critical to attracting new patients. Finally, organizations more generally may want to explore the capabilities of new media and social networking sites for building reputation.

The school nurse, the school social worker, and the school counselor play an important role in promoting the health of children. Health services in the school setting provide opportunities to appraise, protect, and promote student health. The purpose of this study was to identify parents' or caregivers' perceptions and beliefs regarding the importance of schools providing various health services to their elementary school-aged children. In addition, the study examined the levels of parental support for, perceptions of, and contact with school health service personnel. In 2005, a nationally representative random sample of 369 (51% return rate) parents of elementary school-aged children completed the questionnaire developed for this study. A majority of parents/caregivers reported that their child's school had a school nurse (78.8%) and counselor (60.5%), but only 22.6% reported their school had a social worker. A majority of parents/caregivers perceived full-time school nurses (86.3%), school counselors (78.6%), and school social workers (56.3%) as important or extremely important and that schools should be held responsible for having each in their child's elementary school. A majority of parents/caregivers were willing to pay an increase in yearly tax dollars to have full-time school health personnel. This study established a level of parental support for, perceptions of, and contact with school health service personnel. Parents were most supportive of school nurses and should be perceived as allies in ensuring job security.

Midlevel providers (eg, nurse practitioners and physician assistants) have been integrated into orthopaedic systems of care in response to the increasing demand for musculoskeletal care. Few studies have examined patient perspectives toward midlevel providers in orthopaedic sports medicine. To identify perspectives of orthopaedic sports medicine patients regarding midlevel providers, including optimal scope of practice, reimbursement equity with physicians, and importance of the physician's midlevel provider to patients when initially selecting a physician. Cross-sectional study; Level of evidence, 3. A total of 690 consecutive new patients of 3 orthopaedic sports medicine physicians were prospectively administered an anonymous questionnaire prior to their first visit. Content included patient perspectives regarding midlevel provider importance in physician selection, optimal scope of practice, and reimbursement equity with physicians. Of the 690 consecutive patients who were administered the survey, 605 (87.7%) responded. Of these, 51.9% were men and 48.1% were women, with a mean age of 40.5 ± 15.7 years. More than half (51.2%) perceived no differences in training levels between physician assistants and nurse practitioners. A majority of patients (62.9%) reported that the physician's midlevel provider is an important consideration when choosing a new orthopaedic sports medicine physician. Patients had specific preferences regarding which services should be physician provided. Patients also reported specific preferences regarding those services that could be midlevel provided. There lacked a consensus on reimbursement equity for midlevel practitioners and physicians, despite 71.7% of patients responding that the physician provides a higher-quality consultation. As health care becomes value driven and consumer-centric, understanding patient perspectives on midlevel providers will allow orthopaedic sports medicine physicians to optimize efficiency and patient satisfaction. Physicians may consider these data in clinical workforce planning, as patients preferred specific services to be physician or midlevel provided. It may be worthwhile to consider midlevel providers in marketing efforts, given that patients considered the credentials of the physician's midlevel provider when initially selecting a new physician. Patients lacked consensus regarding reimbursement equity between physicians and midlevel providers, despite responding that the physician provides a higher-quality consultation. Our findings are important for understanding the midlevel workforce as it continues to grow in response to the increasing demand for orthopaedic sports care.

2012-04-01

The study examined which socio-demographic differences between clients and providers influenced interpersonal complementarity during an initial intake session; that is, behaviors that facilitate harmonious interactions between client and provider. Complementarity was assessed using blinded ratings of 114 videotaped intake sessions by trained observers. Hierarchical linear models were used to examine how match between client and provider in race/ethnicity, sex, and age were associated with levels of complementarity. A qualitative analysis investigated potential mechanisms that accounted for overall complementarity beyond match by examining client-provider dyads in the top and bottom quartiles of the complementarity measure. Results indicated significant interactions between client's race/ethnicity (Black) and provider's race/ethnicity (Latino) (p = .036) and client's age and provider's age (p = .044) on the Affiliation axis. The qualitative investigation revealed that client-provider interactions in the upper quartile of complementarity were characterized by consistent descriptions between the client and provider of concerns and expectations as well as depictions of what was important during the meeting. Results suggest that differences in social identities, although important, may be overcome by interpersonal variables early in the therapeutic relationship. Implications for both clinical practice and future research are discussed, as are factors relevant to working across cultures.

Whiplash associated disorders (WAD) result in significant personal and economic costs. Patient education and reassurance are recommended treatments for acute WAD but the information needs of patients have not been investigated. To determine what information whiplash-injured patients believe is important to help recovery in the acute stage of injury. A Delphi design survey series with three rounds. Thirty-three participants who had sustained a whiplash injury within the last three years were invited to participate. Participants were asked to provide five statements, in response to an open-ended question, regarding what they believed was the most important information to provide to patients following a whiplash injury. Nineteen patients responded and 85 statements were collected and reviewed independently by two of the authors to remove duplicates. The importance of the remaining items was rated by the participants in the second survey round. Items rated by >50% of participants as important were included in the third survey round. To be deemed key information, >80% of participants had to rate an item as important in this final round. Eighteen items met the criteria for key information. These points addressed four areas: assessment and treatment, recovery and symptoms, patient attitudes during treatment and relationships with health practitioners. The key information points endorsed by patients in this study may provide useful information to constitute a basis for reassurance and education provided to patients with WAD. The results also suggest that improved relationships between patients with whiplash and health practitioners is required. Copyright © 2017 Elsevier Ltd. All rights reserved.

Objectives The purpose of this study was to use a qualitative approach to better understand the importance and efficacy of addressing spiritual issues within an interdisciplinary bone marrow transplant clinic from the perspectives of patients and healthcare providers. Setting Participants were recruited from the bone marrow transplant clinic of a large urban outpatient cancer care centre in western Canada. Participants: Focus groups were conducted with patients (n=7) and healthcare providers (n=9) to explore the importance of addressing spiritual issues across the treatment trajectory and to identify factors associated with effectively addressing these needs. Results Data were analysed using the qualitative approach of latent content analysis. Addressing spiritual issues was understood by patients and healthcare providers, as a core, yet under addressed, component of comprehensive care. Both sets of participants felt that addressing basic spiritual issues was the responsibility of all members of the interdisciplinary team, while recognising the need for specialised and embedded support from a spiritual care professional. While healthcare providers felt that the impact of the illness and treatment had a negative effect on patients’ spiritual well-being, patients felt the opposite. Skills, challenges, key time points and clinical indicators associated with addressing spiritual issues were identified. Conclusions Despite a number of conceptual and clinical challenges associated with addressing spiritual issues patients and their healthcare providers emphasised the importance of an integrated approach whereby basic spiritual issues are addressed by members of the interdisciplinary team and by an embedded spiritual care professional, who in addition also provides specialised support. The identification of clinical issues associated with addressing spiritual needs provides healthcare providers with clinical guidance on how to better integrate this aspect of care into their clinical practice, while also identifying acute incidences when a more targeted and specialised approach may be of benefit.

2015-12-01

The objective of the study was to understand the immediate utility of health information exchange (HIE) on emergency department (ED) providers by interviewing them shortly after the information was retrieved. Prior studies of physician perceptions regarding HIE have only been performed outside of the care environment. Trained research assistants interviewed resident physicians, physician assistants and attending physicians using a semi-structured questionnaire within two hours of making a HIE request. The responses were recorded, then transcribed for qualitative analysis. The transcribed interviews were analyzed for emerging qualitative themes. We analyzed 40 interviews obtained from 29 providers. Primary qualitative themes discovered included the following: drivers for requests for outside information; the importance of unexpected information; historical lab values as reference points; providing context when determining whether to admit or discharge a patient; the importance of information in refining disposition; improved confidence of provider; and changes in decisions for diagnostic imaging. ED providers are driven to use HIE when they're missing a known piece of information. This study finds two additional impacts not previously reported. First, providers sometimes find additional unanticipated useful information, supporting a workflow that lowers the threshold to request external information. Second, providers sometimes report utility when no changes to their existing plan are made as their confidence is increased based on external records. Our findings are concordant with previous studies in finding exchanged information is useful to provide context for interpreting lab results, making admission decisions, and prevents repeat diagnostic imaging.

Aim of the study PROFIL was a prospective observational study conducted to investigate physicians’ evaluation of febrile neutropenia (FN) risk and reasons for giving pegfilgrastim primary prophylaxis (PP) in routine clinical practice in Poland. Material and methods Adult cancer patients treated with chemotherapy (CT), assessed by investigators as having high overall FN risk, and who received pegfilgrastim in cycle 1 were enrolled between 03/2009 and 09/2010. Investigators assessed FN risk of the CT regimen, individual risk factors, and overall FN risk, and were asked to provide the most important reasons for providing pegfilgrastim PP. Investigator-assessed CT FN risk was compared with guideline classification. Results Data were analysed from 1006 breast, ovarian, and lung cancer, and non-Hodgkin (NHL) and Hodgkin lymphoma (HL) patients. The most important reasons for using pegfilgrastim PP were high CT FN risk and advanced disease; these were consistent across tumour types and treatment intent. The investigators generally assessed high CT FN risk in agreement with guideline classification. Febrile neutropenia occurred in 4% of patients, most commonly in HL, NHL, and patients with advanced disease. Conclusions High CT FN risk and advanced stage of disease were found to be the most important reasons for providing pegfilgrastim PP by physicians in Poland. PMID:26557762

To examine the literature from the past 20 years and identify those studies that support the economic merit of health promotion. A panel of experts was used to identify the top studies supporting the purpose of this article. Studies were chosen based on the following criteria: the study (1) examined the relationship between health risks and financial outcomes, or health promotion programs and financial outcomes; (2) provided strong and compelling financial data supporting the worth of health promotion; (3) had a high-quality methodology; (4) answered an important question or replicated important findings with superior methodology; and (5) represented U.S.-based initiatives published since 1980. After initially nominating a group of studies for consideration, panelists rated each on a scale from 1 to 3 representing their opinion of importance. Studies rating the highest were included for this discussion. Studies were analyzed by population characteristics, design, statistical tests, limitations, and results. This information was summarized for each identified article. A relationship between modifiable health risk factors and health care costs is supported by research. Health promotion interventions appear to provide positive financial returns, most notably for health care costs and absenteeism reduction. Private sector initiatives seem to be driving economic-based research. Overall, health promotion shows promising results for providing financial advantages for its sponsors; however, if this discipline is to show its true worth, considerable funding is needed from government or philanthropic sources to cover the substantial costs of quality research.

2016-01-01

Development of effective treatments for alcohol use disorder (AUD) represents an important public health goal. This review provides a summary of completed preclinical and clinical studies testing pharmacotherapies for treatment of AUD. We discuss opportunities for improving the translation from preclinical findings to clinical trial outcomes, focusing on the validity and predictive value of animal and human laboratory models of AUD. Specifically, while preclinical studies of medications development have offered important insights into the neurobiology of the disorder and alcohol's molecular targets, limitations include the lack of standardized methods and streamlined processes whereby animal studies can readily inform human studies. Behavioral pharmacology studies provide a less expensive and valuable opportunity to assess the feasibility of a pharmacotherapy prior to initiating larger scale clinical trials by providing insights into the mechanism of the drug, which can then inform recruitment, analyses, and assessments. Summary tables are provided to illustrate the wide range of preclinical, human laboratory, and clinical studies of medications development for alcoholism. Taken together, this review highlights the challenges associated with animal paradigms, human laboratory studies and clinical trials with the overarching goal of advancing treatment development and highlighting opportunities to bridge the gap between preclinical and clinical research.

Socially important locations are places which are frequently visited by social media users in their social media lifetime. Discovering socially important locations provide several valuable information about user behaviours on social media networking sites. However, discovering socially important locations are challenging due to data volume and dimensions, spatial and temporal calculations, location sparseness in social media datasets, and inefficiency of current algorithms. In the literature, several studies are conducted to discover important locations, however, the proposed approaches do not work in computationally efficient manner. In this study, we propose Fast SS-ILM algorithm by modifying the algorithm of SS-ILM to mine socially important locations efficiently. Experimental results show that proposed Fast SS-ILM algorithm decreases execution time of socially important locations discovery process up to 20 %.

Risk Factors for Progression of Chronic Kidney Disease

Staples, Amy; Wong, Craig

2010-01-01

Purpose of Review Provides an overview of the identified risk factors for chronic kidney disease (CKD) progression emphasizing the pediatric population. Recent findings Over the past ten years, there have been significant changes to our understanding and study of pre-terminal kidney failure. Recent refinements in the measurement of glomerular filtration rate (GFR) and GFR estimating equations are important tools for identification and association of risk factors for CKD progression in children. In pediatric CKD, lower level of kidney function at presentation, higher levels of proteinuria, and hypertension are known markers for a more rapid decline in GFR. Anemia and other reported risk factors from the pre-genomic era have need for further study and validation. Genome-wide association studies have identified genetic loci which have provided novel genetic risk factors for CKD progression. Summary With cohort studies of children with CKD becoming mature, they have started to yield important refinements to the assessment of CKD progression. While many of the traditional risk factors for renal progression will certainly be assessed, such cohorts will be important for evaluating novel risk factors identified by genome-wide studies.

The enduring importance of animal modelsin understanding periodontal disease

Hajishengallis, George; Lamont, Richard J; Graves, Dana T

2015-01-01

Whereas no single animal model can reproduce the complexity of periodontitis, different aspects of the disease can be addressed by distinct models. Despite their limitations, animal models are essential for testing the biological significance of in vitro findings and for establishing cause-and-effect relationships relevant to clinical observations, which are typically correlative. We provide evidence that animal-based studies have generated a durable framework for dissecting the mechanistic basis of periodontitis. These studies have solidified the etiologic role of bacteria in initiating the inflammatory response that leads to periodontal bone loss and have identified key mediators (IL-1, TNF, prostaglandins, complement, RANKL) that induce inflammatory breakdown. Moreover, animal studies suggest that dysbiosis, rather than individual bacterial species, are important in initiating periodontal bone loss and have introduced the concept that organisms previously considered commensals can play important roles as accessory pathogens or pathobionts. These studies have also provided insight as to how systemic conditions, such as diabetes or leukocyte adhesion deficiency, contribute to tissue destruction. In addition, animal studies have identified and been useful in testing therapeutic targets. PMID:25574929

[Quality Management and Quality Specifications of Laboratory Tests in Clinical Studies--Challenges in Pre-Analytical Processes in Clinical Laboratories].

PubMed

Ishibashi, Midori

2015-01-01

The cost, speed, and quality are the three important factors recently indicated by the Ministry of Health, Labour and Welfare (MHLW) for the purpose of accelerating clinical studies. Based on this background, the importance of laboratory tests is increasing, especially in the evaluation of clinical study participants' entry and safety, and drug efficacy. To assure the quality of laboratory tests, providing high-quality laboratory tests is mandatory. For providing adequate quality assurance in laboratory tests, quality control in the three fields of pre-analytical, analytical, and post-analytical processes is extremely important. There are, however, no detailed written requirements concerning specimen collection, handling, preparation, storage, and shipping. Most laboratory tests for clinical studies are performed onsite in a local laboratory; however, a part of laboratory tests is done in offsite central laboratories after specimen shipping. As factors affecting laboratory tests, individual and inter-individual variations are well-known. Besides these factors, standardizing the factors of specimen collection, handling, preparation, storage, and shipping, may improve and maintain the high quality of clinical studies in general. Furthermore, the analytical method, units, and reference interval are also important factors. It is concluded that, to overcome the problems derived from pre-analytical processes, it is necessary to standardize specimen handling in a broad sense.

Individuals in need of psychiatric treatment often avoid seeking help because of stigma. This study examined the impact of two stigma dimensions on help-seeking attitudes. Perceived public stigma refers to discrimination and devaluation by others, and anticipated self-stigma refers to internalization of negative stereotypes about people who seek help. Data were from the 2009 Stigma in a Global Context-Belgian Mental Health Study, in which face-to-face interviews were conducted with a representative sample of the general Belgian population. The study reported here included 728 respondents who received a vignette depicting major depression or schizophrenia. Perceived public stigma and anticipated self-stigma were measured with validated instruments. Respondents' attitudes toward help seeking were measured by the importance they assigned to care from formal and informal providers: general practitioners, psychiatrists, psychologists, family members, or friends. Multiple linear regression models were estimated. Respondents with higher levels of anticipated self-stigma attached less importance to care provided by general practitioners or psychiatrists, and those with higher levels of perceived public stigma rated informal help seeking as less important. The gender and the ethnicity of the person and respondents' sociodemographic characteristics had relatively little effect on help-seeking attitudes. Anticipated self-stigma and perceived public stigma appeared to have a differential impact on attitudes toward formal and informal help seeking. Internalization of negative stereotypes was negatively associated with the perceived importance of care from medical providers (general practitioners and psychiatrists). Awareness of stereotypes held by others deterred respondents from acknowledging the importance of informal care.

It is widely recognised that the quantity and sustainability of new homes in the UK need to increase. However, it is important that sustainable housing is regarded holistically, and not merely in environmental terms, and incorporates elements that enhance the quality of life, health and well-being of its users. This paper focuses on the "soft" features of sustainable housing, that is, the non-technological components of sustainable housing and neighbourhood design that can impact occupants' health and well-being. Aims of the study are to ascertain the relative level of importance that key housing stakeholders attach to these features and to investigate whether the opinions of housing users and housing providers are aligned with regards to their importance. An online survey was carried out to gauge the level of importance that the key stakeholders, such as housing users, local authorities, housing associations, and developers (n = 235), attach to these features. Results revealed that while suitable indoor space was the feature regarded as most important by all stakeholders, there were also a number of disparities in opinion between housing users and housing providers (and among the different types of providers). This implies a scope for initiatives to achieve a better alignment between housing users and providers.

Luquis, Raffy R; Paz, Harold L

2015-09-01

The Patient Protection and Affordable Care Act's emphasis on health promotion and prevention activities required an examination of the current practices of primary care providers in these areas. A total of 196 primary care providers completed a survey to assess current health promotion and prevention attitudes, practices, and barriers. Results of this study showed that family physicians in Pennsylvania recognize the importance of and their role in providing health promotion and prevention and offer advice in key behavioral and disease prevention areas. Results from the study suggest that their ability to provide these services is hindered by a lack of time and the heavy workload. Although most family physicians provided advice to patients in several health promotion and prevention areas, few participants reported that they referred patients to other health professionals. Finally, when it comes to preventive services, participants ranked blood pressure screening, tobacco use screening, and tobacco use cessation interventions as the most important services. Effective implementation of the Patient Protection and Affordable Care Act will require necessary resources and support of primary care providers to help patients achieve healthier lives. © 2014 Society for Public Health Education.

Peroxisome protein import: a complex journey.

Baker, Alison; Lanyon-Hogg, Thomas; Warriner, Stuart L

2016-06-15

The import of proteins into peroxisomes possesses many unusual features such as the ability to import folded proteins, and a surprising diversity of targeting signals with differing affinities that can be recognized by the same receptor. As understanding of the structure and function of many components of the protein import machinery has grown, an increasingly complex network of factors affecting each step of the import pathway has emerged. Structural studies have revealed the presence of additional interactions between cargo proteins and the PEX5 receptor that affect import potential, with a subtle network of cargo-induced conformational changes in PEX5 being involved in the import process. Biochemical studies have also indicated an interdependence of receptor-cargo import with release of unloaded receptor from the peroxisome. Here, we provide an update on recent literature concerning mechanisms of protein import into peroxisomes. © 2016 The Author(s).

Bone Watershed is one of the major watersheds in Gorontalo Province. Bone watershed has a very important role for the people of Gorontalo Province. The role of Bone Watershed is mainly related to the providing clean water, producing oxygen, controlling flood, providing habitat for endemic flora fauna and other environmental functions. The role of Bone Watershed for the community's economic sector is also very important, the Bone watershed provides livelihood for surrounding communities includes fertile land resources for agriculture and plantations, forest products, and livestock feed. This research is important considering the Bone watershed has limited availability of land for agriculture and the high risk of natural disasters such as floods and landslides. Geospatial data includes topography map, landform map, soil map, integrated with field survey results and soil properties were analized to determine conservation management of agriculture land in the Bone Watershed, Gorontalo Province, Indonesia. The result of this study shows that based on soil properties and physical land characteristics, land use for agriculture should consider appropriate conservation techniques, land capability and respect to local wisdom.

Resident transitions to assisted living: a role for social workers.

2012-08-01

This study explored key aspects of resident transitions to assisted living (AL), including the frequency and importance of preadmission resident education and the potential role of social workers in this setting. To examine the factors that may help or hinder resident transitions to AL, a written survey was administered to a statewide, geographically representative purposive sample of Medicaid Assisted Living Waiver providers (N = 28). Findings suggest a positive relationship between the availability of a social worker and the frequency and importance of resident preadmission education in several areas. Results also suggest a gap between what AL providers believe is important for resident transitions and what is actually happening in their facilities. Social workers may play a significant role in providing preadmission education and are well positioned to address the unmet psychosocial needs of residents and family members during the transition to AL. Future studies should specifically examine the contributing role of social workers during the period of adjustment to AL and the effect of social work services on the well-being of AL residents and families in AL settings.

As attention to, and motivation for, EMS-related research continues to grow, particularly exception from informed consent (EFIC) research, it is important to understand the thoughts, beliefs, and experiences of EMS providers who are actively engaged in the research. Study Objective We explored the attitudes, beliefs, and experiences of EMS providers regarding their involvement in prehospital emergency research, particularly EFIC research. Method Using a qualitative design, 24 participants were interviewed including Nationally Registered Paramedics and Virginia certified Emergency Medical Technicians employed at Richmond Ambulance Authority, the participating EMS agency. At the time of our interviews, the EMS agency was involved in an exception from informed consent trial. Transcribed interview data were coded and analyzed for themes. Findings were presented back to the EMS agency for validation. Results Overall, there appeared to be support for prehospital emergency research. Participants viewed research as necessary for the advancement of the field of EMS. Improvement in patient care was identified as one of the most important benefits. A number of ethical considerations were identified: individual risk versus public good and consent. EMS providers in our study were open to working with EMS researchers throughout the community consultation and public disclosure process. Conclusions EMS providers in our study value research and are willing to participate in studies. Support for research was balanced with concerns and challenges regarding the role of providers in the research process. PMID:22823963

Providing care to "very important person" (VIP) patients can pose unique moral and value-based challenges for providers. No studies have examined VIP services in the inpatient setting. Through a multi-institutional survey of hospitalists, we assessed physician viewpoints and behavior surrounding the care of VIP patients. A significant proportion of respondents reported feeling pressured by patients, family members, and hospital representatives to provide unnecessary care to VIP patients. Based on self-reported perceptions, as well as case-based questions, we also found that the VIP status of a patient may impact physician clinical decision-making related to unnecessary medical care. Additional studies to quantify the use of VIP services and its effect on cost, resource availability, and patient-specific outcomes are needed.

Van Hoof, Thomas J; Miller, Nicole E; Meehan, Thomas P

2013-01-01

Educational outreach is a common intervention used to translate research findings into practice; however, the intervention has a mixed effect on changing clinician behavior and improving patient outcomes. Based on a published set of characteristics aimed at standardizing the approach to educational outreach, the authors undertook a careful review of the literature to determine the consistency and completeness of documentation. Using a 25-item abstraction tool, the authors reviewed 68 published studies of a recent Cochrane meta-analysis to determine the extent to which educational outreach studies provide recommended documentation of important characteristics. The results indicate that studies are generally inconsistent (documentation range of 0% to 100% across characteristics) and incomplete (documentation average of 43.1% across studies) in their descriptions. Documentation shortcomings of educational outreach studies make understanding the intervention and interpreting its findings particularly challenging. The authors recommend the creation of a guideline to help improve documentation of educational outreach efforts.

Physical and Chemical Implications of Mid-Winter Pumping of Trunda Lakes - North Slope, Alaska

Tundra lakes on the North Slope, Alaska, are an important resource for energy development and petroleum field operations. A majority of exploration activities, pipeline maintenance, and restoration activities take place on winter ice roads that depend on water availability at key times of the winter operating season. These same lakes provide important fisheries and ecosystem functions. In particular, overwintering habitat for fish is one important management concern. This study focused on the evaluation of winter water use in the current field operating areas to provide a better understanding of the current water use practices. It found that under the currentmore » water use practices, there were no measurable negative effects of winter pumping on the lakes studied and current water use management practices were appropriately conservative. The study did find many areas where improvements in the understanding of tundra lake hydrology and water usage would benefit industry, management agencies, and the protection of fisheries and ecosystems.« less

A traits-based approach for prioritizing species for monitoring and surrogacy selection

The bar for justifying the use of vertebrate animals for study is being increasingly raised, thus requiring increased rigor for species selection and study design. Although we have power analyses to provide quantitative backing for the numbers of organisms used, quantitative backing for selection of study species is not frequently employed. This can be especially important when measuring the impacts of ecosystem alteration, when study species must be chosen that are both sensitive to the alteration and of sufficient abundance for study. Just as important is providing justification for designation of surrogate species for study, especially when the species ofmore » interest is rare or of conservation concern and selection of an appropriate surrogate can have legal implications. In this study, we use a combination of GIS, a fish traits database and multivariate statistical analyses to quantitatively prioritize species for study and to determine potential study surrogate species. We provide two case studies to illustrate our quantitative, traits-based approach for designating study species and surrogate species. In the first case study, we select broadly representative fish species to understand the effects of turbine passage on adult fishes based on traits that suggest sensitivity to turbine passage. In our second case study, we present a framework for selecting a surrogate species for an endangered species. Lastly, we suggest that our traits-based framework can provide quantitative backing and added justification to selection of study species while expanding the inference space of study results.« less

The majority of primary care physicians support integration of children's oral health promotion and disease prevention into their practices but can experience challenges integrating oral health services into their workflow. Most electronic health records (EHRs) in primary care settings do not include oral health information for pediatric patients. Therefore, it is important to understand providers' preferences for oral health information within the EHR. The objectives of this study are to assess (1) the relative importance of various elements of pediatric oral health information for primary care providers to have in the EHR and (2) the extent to which practice and provider characteristics are associated with these information preferences. We surveyed a sample of primary care physicians who conducted Medicaid well-child visits in North Carolina from August - December 2013. Using descriptive statistics, we analyzed primary care physicians' oral health information preferences relative to their information preferences for traditional preventive aspects of well-child visits. Furthermore, we analyzed associations between oral health information preferences and provider- and practice-level characteristics using an ordinary least squares regression model. Fewer primary care providers reported that pediatric oral health information is "very important," as compared to more traditional elements of primary care information, such as tracking immunizations. However, the majority of respondents reported some elements of oral health information as being very important. Also, we found positive associations between the percentage of well child visits in which oral health screenings and oral health referrals are performed and the reported importance of having pediatric oral health information in the EHR. Incorporating oral health information into the EHR may be desirable for providers, particularly those who perform oral health screenings and dental referrals.

Care coordination programmes are an important aspect of HIV management whose success depends largely on HIV primary care provider (PCP) and case manager collaboration. Factors influencing collaboration among HIV PCPs and case managers remain to be studied. The study objective was to test an existing theoretical model of interprofessional collaborative practice and determine which factors play the most important role in facilitating collaboration. A self-administered, anonymous mail survey was sent to HIV PCPs and case managers in New York City. An adapted survey instrument elicited information on demographic, contextual, and perceived social exchange (trustworthiness, role specification, and relationship initiation) characteristics. The dependent variable, perceived interprofessional practice, was constructed from a validated scale. A sequential block wise regression model specifying variable entry order examined the relative importance of each group of factors and of individual variables. The analysis showed that social exchange factors were the dominant drivers of collaboration. Relationship initiation was the most important predictor of interprofessional collaboration. Additional influential factors included organisational leadership support of collaboration, practice settings, and frequency of interprofessional meetings. Addressing factors influencing collaboration among providers will help public health programmes optimally design their structural, hiring, and training strategies to foster effective social exchanges and promote collaborative working relationships.

Contextual influence on evaluation capacity building in a rapidly changing environment under new governmental policies.

Evaluation capacity building (ECB) is a context-dependent process. Contextual factors affecting ECB implementation have been explored theoretically and practically, but their influence within a changing environment has seldom been discussed. This study examined essential context-sensitive parameters, particularly those involved in implementing new governmental policies regarding higher education. Taiwan was used as a case study for exploring the effect of contextual change on ECB attributes from the perspectives of training receivers and providers. Surveys and interviews were used for data collection and importance-performance analysis was applied for data analysis. Four prominent features were identified. First, the ECB attributes perceived as important by receivers were performed adequately, whereas those perceived as less important were performed less well. Second, under new policies, training provider designed training covering a wide range of ECB, whereas receivers focused on those can be directly applied in evaluation process. Third, in a small education system such as Taiwan's, the complexity of peer review is high and ethical issues become important. Fourth, because the evaluation structure has been changed from single- to dual-track, receivers expect more training for institution staff, whereas providers insist on hierarchical training. Aligning ECB supply and needs is paramount for adaptation to new policies. Copyright © 2017 Elsevier Ltd. All rights reserved.

Attitude importance as a moderator of the relationship between implicit and explicit attitude measures.

PubMed

Karpinski, Andrew; Steinman, Ross B; Hilton, James L

2005-07-01

The authors examined attitude importance as a moderator of the relationship between the Implicit Association Test (IAT) and explicit attitude measures. In Study 1 (N = 194), as ratings of attitude importance regarding the 2000 presidential election increased, the strength of the relationship between a Bush-Gore IAT and explicit attitude measures also increased. Study 2 provided a conceptual replication of these results using attitudes toward Coke and Pepsi (N = 112). In addition, across both studies, explicit attitude measures were better predictors of deliberative behaviors than IAT scores. In Study 3 (N = 77), the authors examined the role of elaboration as a mechanism by which attitude importance may moderate IAT-explicit attitude correlations. As predicted, increased elaboration resulted in stronger IAT-explicit attitude correlations. Other possible mechanisms by which attitude importance may moderate the IAT-explicit attitude relationship also are discussed.

Fish trypanosomes are widely distributed in commercially important fish, with high prevalence in some Brazilian species. This study provides the first record of the isolation and in vitro maintenance of trypanosomes from Brazilian fish. We produced 49 trypanosome isolates from naturally infected catfish (Hypostomus affinis and Hypostomus luetkeni), using 9 different culture media (out of 31 tested). Trypanosomes were maintained in culture for at least 15 mo and were successfully cryopreserved. Culture forms-epimastigotes and short trypomastigotes-were capable of dividing in vitro. Our study is an important step in the investigation of ultrastructure, taxonomy, and phylogeny of trypanosomes from commercially important Brazilian fish.

Exploring the Links between Post-Industrial Landscape History and Ecology through Participatory Methods

PubMed Central

2015-01-01

There is increasing recognition of the importance for local biodiversity of post-mining sites, many of which lie near communities that have suffered significant social and economic deprivation as the result of mine closures. However, no studies to date have actively used the knowledge of local communities to relate the history and treatment of post-mining sites to their current ecological status. We report a study of two post-mining sites in the Yorkshire coalfield of the UK in which the local community were involved in developing site histories and assessing plant and invertebrate species composition. Site histories developed using participatory GIS revealed that the sites had a mixture of areas of spontaneous succession and technical reclamation, and identified that both planned management interventions and informal activities influenced habitat heterogeneity and ecological diversity. Two groups of informal activity were identified as being of particular importance. Firstly, there has been active protection by the community of flower-rich habitats of conservation value (e.g. calcareous grassland) and distinctive plant species (e.g. orchids) which has also provided important foraging resources for butterfly and bumblebee species. Secondly, disturbance by activities such as use of motorbikes, informal camping, and cutting of trees and shrubs for fuel, as well as planned management interventions such as spreading of brick rubble, has provided habitat for plant species of open waste ground and locally uncommon invertebrate species which require patches of bare ground. This study demonstrates the importance of informal, and often unrecorded, activities by the local community in providing diverse habitats and increased biodiversity within a post-mining site, and shows that active engagement with the local community and use of local knowledge can enhance ecological interpretation of such sites and provide a stronger basis for successful future management.

Printed educational materials are a common source of health information, although their effectiveness in improving women's knowledge or self-care in pregnancy has been questioned. This study describes the information in printed educational materials that address healthy eating during pregnancy and gestational weight gain (GWG) that are currently used in Alberta, Canada. Content of 6 resources was analyzed using a constant comparison qualitative approach. Resources emphasized healthy eating, prenatal supplements, folate supplementation, and healthy weight gain. More resources discussed the importance of "eating enough" than provided guidance on avoiding excessive GWG. Themes identified were: "everything is important" meaning that all healthy behaviours are important, making prioritization difficult; "more is more" emphasized eating more over moderation; "everyone is individual" suggests women seek individualized care through the care provider; and "contradictions" describes differences in content and recommendations within and between resources. New or revised versions of resources should provide congruent information with up-to-date recommendations that are easily prioritized. Care providers should be aware of contradictory information or information that does not align with current recommendations within printed educational materials and be ready to help women address the areas important for her personal behaviour change.

Nurses' views about productivity and management factors affecting it have been identified as the most important aspects affecting productivity. Thus, this study assesses productivity from the nurse's view. A grounded theory approach was used for this research. Purposive sampling and semistructured interviews were used. The data were analyzed using constant comparative analysis. Most participants felt that the qualitative nature (effectiveness) of productivity is very important. Also, participants indicated that management is the most important factor that can promote or impede their productivity. They suggested that managers' performance and their skill level are the factors influencing productivity. Effective management can improve nurses' productivity and the quality of care that nurses provide.

Marine systems are very diverse and recognized as being sources of a wide range of biomolecules. This review provides an overview of metabolite profiling based on mass spectrometry (MS) approaches in marine organisms and their environments, focusing on recent advances in the field. We also point out some of the technical challenges that need to be overcome in order to increase applications of metabolomics in marine systems, including extraction of chemical compounds from different matrices and data management. Metabolites being important links between genotype and phenotype, we describe added value provided by integration of data from metabolite profiling with other layers of omics, as well as their importance for the development of systems biology approaches in marine systems to study several biological processes, and to analyze interactions between organisms within communities. The growing importance of MS-based metabolomics in chemical ecology studies in marine ecosystems is also illustrated. PMID:22690147

Identifying essential genes in a given organism is important for research on their fundamental roles in organism survival. Furthermore, if possible, uncovering the links between core functions or pathways with these essential genes will further help us obtain deep insight into the key roles of these genes. In this study, we investigated the essential and non-essential genes reported in a previous study and extracted gene ontology (GO) terms and biological pathways that are important for the determination of essential genes. Through the enrichment theory of GO and KEGG pathways, we encoded each essential/non-essential gene into a vector in which each component represented the relationship between the gene and one GO term or KEGG pathway. To analyze these relationships, the maximum relevance minimum redundancy (mRMR) was adopted. Then, the incremental feature selection (IFS) and support vector machine (SVM) were employed to extract important GO terms and KEGG pathways. A prediction model was built simultaneously using the extracted GO terms and KEGG pathways, which yielded nearly perfect performance, with a Matthews correlation coefficient of 0.951, for distinguishing essential and non-essential genes. To fully investigate the key factors influencing the fundamental roles of essential genes, the 21 most important GO terms and three KEGG pathways were analyzed in detail. In addition, several genes was provided in this study, which were predicted to be essential genes by our prediction model. We suggest that this study provides more functional and pathway information on the essential genes and provides a new way to investigate related problems.

Service quality (SQ) generally refers to the nonclinical aspects of health services and primarily focuses on the relationship between the care provider and the customers, and the environment in which care services are delivered. The aim of this study was to assess the SQ provided for myocardial infarction (MI) from the patients' perspective. A cross-sectional study was conducted with 164 patients with MI at the Tabriz Shahid Madani cardiology clinic. Study participants were selected using convenience sampling. SQ was measured using a validated Comprehensive Quality Measurement in Healthcare SQ questionnaire. The reliability was confirmed based on Cronbach's alpha coefficient (α=0.81). SQ was calculated using the formula SQ=10- (importance × performance), based on the importance and performance of non-health-related aspects from the customers' perspective. Importance scores ranged from 1 to 10 and performance was scored between 0 and 1. Of 164 participants, about 75% were men and almost 44% were between 51 and 65 years of age. From the customers' perspective, the total SQ score was 6.80 (0-10 scale), and the individual scores for all SQ aspects were below an acceptable level. Confidentiality, dignity and continuity were given the highest scores, while availability of support groups had the lowest score. The study findings revealed an opportunity to improve SQ. Patient and provider participation in quality improvement activities could be an effective strategy to improve the aspects of health care quality that were most important to the customers and those with low scores, such as availability of support groups.

Direct-to-consumer (DTC) telemedicine providers has the potential to change the traditional patient-physician relationship. Professional medical organizations recommend that telemedicine exist within the medical home. This study aims to understand patients' preferences and desires for DTC telemedicine. We conducted a nationwide survey of 4345 survey respondents demographically balanced to represent the United States adult population. The survey consisted of questions assessing the respondents' attributes and their willingness and comfortability using telemedicine as well as the importance and desired attributes of a provider providing care via telemedicine. Relatively few respondents (3.5%) had ever had an online video visit with their care provider. Respondents were more willing to see their own provider via telemedicine than unwilling (52% vs. 25%). Additionally, respondents were less willing to use telemedicine to see a different provider from the same healthcare organization (35%) and were least willing to see a different provider from a different organization (19%). Forty-one percent of respondents felt it was unimportant that their current provider offer telemedicine, and only 15% would consider leaving their current provider to a new provider who offers telemedicine as an option. More than half (56%) of respondents felt it was important to have an established relationship with a provider they're having a telemedicine visit with. Nearly two-thirds of respondents (60%) felt it was important for a telemedicine provider to have access to their health records. Patients prefer to use telemedicine with their own doctor with whom they have an established relationship.

This study investigated the current state of health sciences libraries' provision of culturally competent services to support health professions education and patient care and examined factors associated with cultural competency in relation to library services and professional development. This was a cross-sectional study. Data were collected with a survey questionnaire that was distributed via SurveyMonkey to several health sciences librarian email discussion lists. Out of 176 respondents, 163 reported serving clients from diverse cultural backgrounds. Various services were provided to develop or support initiatives in cultural competency in health professions education and patient care. A considerable number of respondents were unsure or reported no library services to support initiatives in cultural competency, although a majority of respondents perceived the importance of providing culturally competent library services (156, 89.1%) and cultural competency for health sciences librarians (162, 93.1%). Those who self-identified as nonwhites perceived culturally competent services to be more important than whites ( p =0.04). Those who spoke another language in addition to English had higher self-rated cultural competency ( p =0.01) than those who only spoke English. These findings contribute to our knowledge of the types of library services provided to support cultural competency initiatives and of health sciences librarians' perceived importance in providing culturally competent library services and cultural competency for health sciences librarians. The results suggest implications for health sciences libraries in fostering professional development in cultural competency and in providing culturally competent services to increase library use by people from a wide range of cultures and backgrounds.

Vanlaere, Linus; Timmermann, Madeleine; Stevens, Marleen; Gastmans, Chris

2012-01-01

In recent approaches to ethics, the personal involvement of health care providers and their empathy are perceived as important elements of an overall ethical ability. Experiential working methods are used in ethics education to foster, inter alia, empathy. In 2008, the care-ethics lab 'sTimul' was founded in Flanders, Belgium, to provide training that focuses on improving care providers' ethical abilities through experiential working simulations. The curriculum of sTimul focuses on empathy sessions, aimed at care providers' empathic skills. The present study provides better insight into how experiential learning specifically targets the empathic abilities of care providers. Providing contrasting experiences that affect the care providers' self-reflection seems a crucial element in this study. Further research is needed to provide more insight into how empathy leads to long-term changes in behaviour.

Self-management support is an integral part of current chronic care guidelines. The success of self-management interventions varies between individual patients, suggesting a need for tailored self-management support. Understanding the role of patient factors in the current decision making of health professionals can support future tailoring of self-management interventions. The aim of this study is to identify the relative importance of patient factors in health professionals' decision making regarding self-management support. A factorial survey was presented to primary care physicians and nurses. The survey consisted of clinical vignettes (case descriptions), in which 11 patient factors were systematically varied. Each care provider received a set of 12 vignettes. For each vignette, they decided whether they would give this patient self-management support and whether they expected this support to be successful. The associations between respondent decisions and patient factors were explored using ordered logit regression. The survey was completed by 60 general practitioners and 80 nurses. Self-management support was unlikely to be provided in a third of the vignettes. The most important patient factor in the decision to provide self-management support as well as in the expectation that self-management support would be successful was motivation, followed by patient-provider relationship and illness perception. Other factors, such as depression or anxiety, education level, self-efficacy and social support, had a small impact on decisions. Disease, disease severity, knowledge of disease, and age were relatively unimportant factors. This is the first study to explore the relative importance of patient factors in decision making and the expectations regarding the provision of self-management support to chronic disease patients. By far, the most important factor considered was patient's motivation; unmotivated patients were less likely to receive self-management support. Future tailored interventions should incorporate strategies to enhance motivation in unmotivated patients. Furthermore, care providers should be better equipped to promote motivational change in their patients.

ABSTRACT The aim of this study is to obtain a systems-level understanding of the interactions between Dehalococcoides and corrinoid-supplying microorganisms by analyzing community structures and functional compositions, activities, and dynamics in trichloroethene (TCE)-dechlorinating enrichments. Metagenomes and metatranscriptomes of the dechlorinating enrichments with and without exogenous cobalamin were compared. Seven putative draft genomes were binned from the metagenomes. At an early stage (2 days), more transcripts of genes in the Veillonellaceae bin-genome were detected in the metatranscriptome of the enrichment without exogenous cobalamin than in the one with the addition of cobalamin. Among these genes, sporulation-related genes exhibited the highest differential expression when cobalamin was not added, suggesting a possible release route of corrinoids from corrinoid producers. Other differentially expressed genes include those involved in energy conservation and nutrient transport (including cobalt transport). The most highly expressed corrinoid de novo biosynthesis pathway was also assigned to the Veillonellaceae bin-genome. Targeted quantitative PCR (qPCR) analyses confirmed higher transcript abundances of those corrinoid biosynthesis genes in the enrichment without exogenous cobalamin than in the enrichment with cobalamin. Furthermore, the corrinoid salvaging and modification pathway of Dehalococcoides was upregulated in response to the cobalamin stress. This study provides important insights into the microbial interactions and roles played by members of dechlorinating communities under cobalamin-limited conditions. IMPORTANCE The key chloroethene-dechlorinating bacterium Dehalococcoides mccartyi is a cobalamin auxotroph, thus acquiring corrinoids from other community members. Therefore, it is important to investigate the microbe-microbe interactions between Dehalococcoides and the corrinoid-providing microorganisms in a community. This study provides systems-level information, i.e., taxonomic and functional compositions and dynamics of the supportive microorganisms in dechlorinating communities under different cobalamin conditions. The findings shed light on the important roles of Veillonellaceae species in the communities compared to other coexisting community members in producing and providing corrinoids for Dehalococcoides species under cobalamin-limited conditions.

T. E. Joiner's (2004, in press) theory of suicidal behavior suggests that past suicidal behavior plays an important role in future suicidality. However, the mechanism by which this risk is transferred and the causal implications have not been well studied. The current study provides evaluation of the nature and limits of this relationship across 4 populations, with varying degrees of suicidal behavior. Across settings, age groups, and impairment levels, the association between past suicidal behavior and current suicidal symptoms held, even when controlling for strong covariates like hopelessness and symptoms of various Axis I and II syndromes. Results provide additional support for the importance of past suicidality as a substantive risk factor for later suicidal behavior. Copyright 2005 APA, all rights reserved.

Ventral anterior cingulate cortex and social decision-making.

Lockwood, Patricia L; Wittmann, Marco K

2018-06-07

Studies in the field of social neuroscience have recently made use of computational models of decision-making to provide new insights into how we learn about the self and others during social interactions. Importantly, these studies have increasingly drawn attention to brain areas outside of classical cortical "social brain" regions that may be critical for social processing. In particular, two portions of the ventral anterior cingulate cortex (vACC), subgenual anterior cingulate cortex and perigenual anterior cingulate cortex, have been linked to social and self learning signals, respectively. Here we discuss the emerging parallels between these studies. Uncovering the function of vACC during social interactions could provide important new avenues to understand social decision-making in health and disease. Copyright © 2018 Elsevier Ltd.

Diffusive supersonic radiation transport, where the ratio of the diffusive radiation front velocity to the material sound speed >2 has been studied in experiments on low density (40 mg/cc to 50 mg/cc) foams. Laser-heated Au hohlraums provided a radiation drive that heated SiO2 and Ta2O5 aerogel foams of varying lengths. Face-on emission measurements at 550 eV provided clean signatures of the radiation breakout. The high quality data provides new detailed information on the importance of both the fill and wall material opacities and heat capacities in determining the radiation front speed and curvature. The Marshak radiation wave transport is studied in a geometry that allows direct comparisons with analytic models and two-dimensional code simulations. Experiments show important effects that will affect even nondiffusive and transonic radiation transport experiments studied by others in the field. This work is of basic science interest with applications to inertial confinement fusion and astrophysics.

Conducting interactive experiments online.

Arechar, Antonio A; Gächter, Simon; Molleman, Lucas

Online labor markets provide new opportunities for behavioral research, but conducting economic experiments online raises important methodological challenges. This particularly holds for interactive designs. In this paper, we provide a methodological discussion of the similarities and differences between interactive experiments conducted in the laboratory and online. To this end, we conduct a repeated public goods experiment with and without punishment using samples from the laboratory and the online platform Amazon Mechanical Turk. We chose to replicate this experiment because it is long and logistically complex. It therefore provides a good case study for discussing the methodological and practical challenges of online interactive experimentation. We find that basic behavioral patterns of cooperation and punishment in the laboratory are replicable online. The most important challenge of online interactive experiments is participant dropout. We discuss measures for reducing dropout and show that, for our case study, dropouts are exogenous to the experiment. We conclude that data quality for interactive experiments via the Internet is adequate and reliable, making online interactive experimentation a potentially valuable complement to laboratory studies.

Siblings' coping strategies and mental health services: a national study of siblings of persons with schizophrenia.

This study examined the helpfulness of coping strategies and the relative importance of mental health services in coping with schizophrenia from the perspective of siblings. This article presents selected survey data from a national study of 746 respondents that investigated the impact of schizophrenia on siblings' lives. The authors developed the Friedrich-Lively Instrument to Assess the Impact of Schizophrenia on Siblings (FLIISS), a closed-ended questionnaire that included questions about coping strategies and mental health services. Respondents identified services for the ill sibling, including symptom control, adequate housing, and long-term planning, as more important than direct services for themselves. The top-ranked coping strategies were education about schizophrenia, a supportive family, and seeing the ill sibling suffer less because symptoms were controlled. Understanding that families were not to blame for schizophrenia was the most helpful coping strategy for nearly three-fourths of siblings. Siblings had little contact with providers in the past; yet the majority of siblings wanted providers to be available to answer questions and clarify their role in future care. At the time of the study, respondents provided social support and helped with crises, but few coordinated the total care. Siblings identified multiple ways that providers can support and assist them in coping with the impact of schizophrenia. Education and support for siblings without schizophrenia and services for their ill siblings will become increasingly important for the well-being of siblings as they are faced with the responsibility of being the primary caregivers in the future.

The spectroscopic analysis of pristine cometary material provides a very important probe of the chemical identity of the material as well as of the physical and chemical conditions which prevailed during the comet's history. Concerning classical spectroscopy, the spectral regions which will most likely prove most useful are the infrared, the visible and ultraviolet. Newer spectroscopic techniques which have the potential to provide equally important information include nuclear magnetic resonance (NMR) and electron spin resonance (ESR). Each technique is summarized with emphasis placed on the kind of information which can be obtained.

Importance and performance of managerial skills in the Australian aged care sector - a middle managers' perspective.

Meissner, Ellen; Radford, Katrina

2015-09-01

This study examined the importance and performance of middle managers' skills to provide a starting point for a sector-wide leadership and management framework. There is an increasing consensus that the quality of management, leadership and performance of any organisation is directly linked to the capabilities of its middle managers and the preparation and on-going training they receive. A total of 199 middle managers from three aged care organisations in Australia participated in a questionnaire conducted during 2010-2011. This study found that middle managers perceived the need to develop their communication skills, self-awareness, change management, conflict resolution and leadership skills. Middle managers perceive a discrepancy between performance and importance of various managerial skills. This study demonstrated that provision of training needs to go beyond clinical skills development and further investigation into managers' needs is necessary, particularly considering the diversity of this critical group in organisations. Future training opportunities provided to middle managers need to address the 'softer' skills (e.g. communication) rather than 'technical' skills (e.g. clinical skills). The provision of training in these skills may improve their performance, which may also lead to increased job satisfaction, continuity in leadership and management and ultimately improvements in the quality of care provided. © 2014 John Wiley & Sons Ltd.

The ability to identify factors responsible for disease in all species depends on the ability to separate those factors which are environmental from those that are intrinsic. This is particularly important for studies on the development of the adaptive immune response of neonates. Studies on laboratory rodents or primates have been ambiguous because neither the effect of environmental nor maternal factors on the newborn can be controlled in mammals that: (i) transmit potential maternal immunoregulatory factors in utero and (ii) are altricial and cannot be reared after birth without their mothers. Employing the newborn piglet model can address each of these concerns. However, it comes at the price of having first to characterize the immune system of swine and its development. This review focuses on the porcine B cell system, especially on the methods used for its characterization in fetal studies and neonatal piglets. Understanding these procedures is important in the interpretation of the data obtained. Studies on neonatal piglets have (a) provided valuable information on the development of the adaptive immune system, (b) lead to important advances in evolutionary biology, (c) aided our understanding of passive immunity and (d) provided opportunities to use swine to address specific issues in veterinary and biomedical research and immunotherapy. This review summarizes the history of the development of the piglet as a model for antibody repertoire development, thus providing a framework to guide future investigators. PMID:19056129

Integrating data from an online diabetes prevention program into an electronic health record and clinical workflow, a design phase usability study.

Health information is increasingly being digitally stored and exchanged. The public is regularly collecting and storing health-related data on their own electronic devices and in the cloud. Diabetes prevention is an increasingly important preventive health measure, and diet and exercise are key components of this. Patients are turning to online programs to help them lose weight. Despite primary care physicians being important in patients' weight loss success, there is no exchange of information between the primary care provider (PCP) and these online weight loss programs. There is an emerging opportunity to integrate this data directly into the electronic health record (EHR), but little is known about what information to share or how to share it most effectively. This study aims to characterize the preferences of providers concerning the integration of externally generated lifestyle modification data into a primary care EHR workflow. We performed a qualitative study using two rounds of semi-structured interviews with primary care providers. We used an iterative design process involving primary care providers, health information technology software developers and health services researchers to develop the interface. Using grounded-theory thematic analysis 4 themes emerged from the interviews: 1) barriers to establishing healthy lifestyles, 2) features of a lifestyle modification program, 3) reporting of outcomes to the primary care provider, and 4) integration with primary care. These themes guided the rapid-cycle agile design process of an interface of data from an online diabetes prevention program into the primary care EHR workflow. The integration of external health-related data into the EHR must be embedded into the provider workflow in order to be useful to the provider and beneficial for the patient. Accomplishing this requires evaluation of that clinical workflow during software design. The development of this novel interface used rapid cycle iterative design, early involvement by providers, and usability testing methodology. This provides a framework for how to integrate external data into provider workflow in efficient and effective ways. There is now the potential to realize the importance of having this data available in the clinical setting for patient engagement and health outcomes.

2017-01-01

The person-centered perspective of residential care facility (RCF) residents with dementia with regard to their intimate and sexual lives is largely neglected in research. We aim to provide methodological considerations and reflections on a performed qualitative study. Recommendations and a guide to study design are provided to inform and encourage future research on the inclusion of people with dementia as participants. Methodological recommendations and reflections are described in chronological order of the procedure. Fragments of interviews are included for further illustration and clarification. Considering preparation, close involvement of clinical practice, and extensive deliberation regarding study design tended to be important. Considering procedure, investment in contacts with clinical practice and authorized representatives; an introduction meeting; person-centered inclusion and consent; profound skills in interviewing participants with dementia; and flexibility in data collection were proven of importance. Considering data analysis and study quality, including field notes and aiming at a balance between study quality and practicability to enhance study 'rigor' were found important. Including the person-centered perspective in research on intimacy and sexuality of RCF residents with dementia, is challenging and takes a flexible and creative approach. It is, however, worthwhile to close the gap in literature.

Goal importance within planned behaviour theory as 'the' predictor of study behaviour in college.

PubMed

Sideridis, G D; Kaissidis-Rodafinos, A

2001-12-01

The theory of planned behaviour has been rarely used for the explanation of student study behaviour and achievement. Although successful, the theory has been criticised for not including important cognitions, so goal importance was added in the present study. Goal importance refers to the weight-importance an individual assigns towards achieving a specific goal (Hollenbeck & Williams, 1987). The purpose of Study 1 was to explain the study behaviour habits of first year college students, using a) Ajzen and Madden's (1986) theory of planned behaviour, and b) planned behaviour with the addition of goal importance. The purpose of Study 2 was to replicate the findings of Study 1. The sample of Study 1 included 149 first year students of an American College located in northern Greece. Study 2 included 85 first year students of the same institution. The students in Study 1 were given a questionnaire four weeks prior to the end of the spring 1998 semester, and those in Study 2 in the autumn of 1998, including all elements of the theory of planned behaviour and goal importance. The data were modelled using Covariance Structural Modelling (CSM) and EQS 5.7b (Bentler, 1998). The planned behaviour model was not well supported in Study 1 providing a Comparative Fit Index (CFI) of.83. However, when goal importance was included in the equation, the resulting structural model produced a CFI of.94. The final structural model of Study 1 was re-tested with the sample of Study 2 and produced a CFI =.95. Findings suggest that goal importance is the causal agent in directing all elements necessary to achieve high levels of study behaviour. Future studies should examine the role of goal importance with other behaviours as well.

Porosity, permeability and 3D fracture network characterisation of dolomite reservoir rock samples

2015-01-01

With fractured rocks making up an important part of hydrocarbon reservoirs worldwide, detailed analysis of fractures and fracture networks is essential. However, common analyses on drill core and plug samples taken from such reservoirs (including hand specimen analysis, thin section analysis and laboratory porosity and permeability determination) however suffer from various problems, such as having a limited resolution, providing only 2D and no internal structure information, being destructive on the samples and/or not being representative for full fracture networks. In this paper, we therefore explore the use of an additional method – non-destructive 3D X-ray micro-Computed Tomography (μCT) – to obtain more information on such fractured samples. Seven plug-sized samples were selected from narrowly fractured rocks of the Hauptdolomit formation, taken from wellbores in the Vienna basin, Austria. These samples span a range of different fault rocks in a fault zone interpretation, from damage zone to fault core. We process the 3D μCT data in this study by a Hessian-based fracture filtering routine and can successfully extract porosity, fracture aperture, fracture density and fracture orientations – in bulk as well as locally. Additionally, thin sections made from selected plug samples provide 2D information with a much higher detail than the μCT data. Finally, gas- and water permeability measurements under confining pressure provide an important link (at least in order of magnitude) towards more realistic reservoir conditions. This study shows that 3D μCT can be applied efficiently on plug-sized samples of naturally fractured rocks, and that although there are limitations, several important parameters can be extracted. μCT can therefore be a useful addition to studies on such reservoir rocks, and provide valuable input for modelling and simulations. Also permeability experiments under confining pressure provide important additional insights. Combining these and other methods can therefore be a powerful approach in microstructural analysis of reservoir rocks, especially when applying the concepts that we present (on a small set of samples) in a larger study, in an automated and standardised manner.

With fractured rocks making up an important part of hydrocarbon reservoirs worldwide, detailed analysis of fractures and fracture networks is essential. However, common analyses on drill core and plug samples taken from such reservoirs (including hand specimen analysis, thin section analysis and laboratory porosity and permeability determination) however suffer from various problems, such as having a limited resolution, providing only 2D and no internal structure information, being destructive on the samples and/or not being representative for full fracture networks. In this paper, we therefore explore the use of an additional method - non-destructive 3D X-ray micro-Computed Tomography (μCT) - to obtain more information on such fractured samples. Seven plug-sized samples were selected from narrowly fractured rocks of the Hauptdolomit formation, taken from wellbores in the Vienna basin, Austria. These samples span a range of different fault rocks in a fault zone interpretation, from damage zone to fault core. We process the 3D μCT data in this study by a Hessian-based fracture filtering routine and can successfully extract porosity, fracture aperture, fracture density and fracture orientations - in bulk as well as locally. Additionally, thin sections made from selected plug samples provide 2D information with a much higher detail than the μCT data. Finally, gas- and water permeability measurements under confining pressure provide an important link (at least in order of magnitude) towards more realistic reservoir conditions.

Latinos are the largest and fastest growing minority population group in the United States, and children in low-income Latino families are at elevated risk of becoming overweight or having obesity. A child’s home is an important social environment in which he/she develops and maintains dietary and physical activity (PA) habits that ultimately impact weight status. Previous research suggests the parents are central to creating a home environment that facilitates or hinders the development of children’s early healthy eating and PA habits. Therefore, the purpose of this study was to explore low-income Latino parents’ beliefs, parenting styles, and parenting practices related to their children’s eating and PA behaviors while at home. Qualitative study using focus group discussions (FGDs) with 33 low-income Latino parents of preschool children 2 to 5 years of age. FGDs were transcribed verbatim and analyzed using thematic analysis. Data analyses revealed that most parents recognize the importance of healthy eating and PA for their children and themselves. However, daily life demands including conflicting schedules, long working hours, financial constraints, and neighborhood safety concerns, etc., impact parents’ ability to create a home environment supportive of these behaviors. This study provides information about how the home environment may influence low-income Latino preschool children’s eating and PA habits, which may be useful for health promotion and disease prevention efforts targeting low-income Latino families with young children, and for developing home-based and parenting interventions to prevent and control childhood obesity among this population group. Pediatric healthcare providers can play an important role in facilitating communication, providing education, and offering guidance to low-income Latino parents that support their children’s development of early healthy eating and PA habits, while taking into account daily life barriers faced by families. Moreover, pediatric healthcare providers also can play an important role in the integration and coordination of home-visitations to complement office-based visits and provide a continuum of care to low-income Latino families.

Link importance incorporated failure probability measuring solution for multicast light-trees in elastic optical networks

2018-03-01

The light-tree-based optical multicasting (LT-OM) scheme provides a spectrum- and energy-efficient method to accommodate emerging multicast services. Some studies focus on the survivability technologies for LTs against a fixed number of link failures, such as single-link failure. However, a few studies involve failure probability constraints when building LTs. It is worth noting that each link of an LT plays different important roles under failure scenarios. When calculating the failure probability of an LT, the importance of its every link should be considered. We design a link importance incorporated failure probability measuring solution (LIFPMS) for multicast LTs under independent failure model and shared risk link group failure model. Based on the LIFPMS, we put forward the minimum failure probability (MFP) problem for the LT-OM scheme. Heuristic approaches are developed to address the MFP problem in elastic optical networks. Numerical results show that the LIFPMS provides an accurate metric for calculating the failure probability of multicast LTs and enhances the reliability of the LT-OM scheme while accommodating multicast services.

While each of the three different screening comparisons made in this report (i.e., within-medium evaluation, between-media evaluation and relative importance grouping) individually provides information potentially of value in focusing future studies, each one is subject to a variety of limitations, the most important being associated with the absence or variable quality of environmental data for a number of the contaminants and media. These screening exercises are intended to provide an initial framework for approaching the study of an extremely complex site. Other approaches could very well yield somewhat different priorities, and the identification or reinterpretation of data in subsequent detailedmore » studies are likely to invalidate some of the results of these screening exercises. However, these evaluations provide a logical approach to defining initial off- site health impact study priorities for the ORR. Therefore, while care must be taken in attempting to make any broad generalizations or greatly simplifying assumptions with regard to the potential health hazards posed by the complex releases from the Reservation, Table 6-1 represents an attempt to summarize a set of recommendations that are derived from the screening exercises presented in this report. Table 6-1 identifies the facilities, processes and contaminants believed to have the highest potential for resulting in off-site health impacts. Table 6-2 identifies contaminants for which no ranking could be performed as part of this feasibility study, because of the absence of any appropriate data for any environmental medium.« less

A Pilot Study on Integrating Videography and Environmental Microbial Sampling to Model Fecal Bacterial Exposures in Peri-Urban Tanzania.

PubMed

Julian, Timothy R; Pickering, Amy J

2015-01-01

Diarrheal diseases are a leading cause of under-five mortality and morbidity in sub-Saharan Africa. Quantitative exposure modeling provides opportunities to investigate the relative importance of fecal-oral transmission routes (e.g. hands, water, food) responsible for diarrheal disease. Modeling, however, requires accurate descriptions of individuals' interactions with the environment (i.e., activity data). Such activity data are largely lacking for people in low-income settings. In the present study, we collected activity data and microbiological sampling data to develop a quantitative microbial exposure model for two female caretakers in peri-urban Tanzania. Activity data were combined with microbiological data of contacted surfaces and fomites (e.g. broom handle, soil, clothing) to develop example exposure profiles describing second-by-second estimates of fecal indicator bacteria (E. coli and enterococci) concentrations on the caretaker's hands. The study demonstrates the application and utility of video activity data to quantify exposure factors for people in low-income countries and apply these factors to understand fecal contamination exposure pathways. This study provides both a methodological approach for the design and implementation of larger studies, and preliminary data suggesting contacts with dirt and sand may be important mechanisms of hand contamination. Increasing the scale of activity data collection and modeling to investigate individual-level exposure profiles within target populations for specific exposure scenarios would provide opportunities to identify the relative importance of fecal-oral disease transmission routes.

In many countries, GPs and home care nurses are involved in care for patients with advanced cancer. Given the varied and complex needs of these patients, providing satisfactory care is a major challenge for them. We therefore aimed to study which aspects of care patients, GPs and home care nurses consider important and whether patients receive these aspects. Seventy-two Dutch patients with advanced cancer, 87 GPs and 26 home care nurses rated the importance of support when experiencing symptoms, respect for patients' autonomy and information provision. Patients also rated whether they received these aspects. Questionnaires were based on the CQ index palliative care. Almost all patients rated information provision and respect for their autonomy as important. The majority also rated support when suffering from specific symptoms as important, especially support when in pain. In general, patients received the care they considered important. However, 49% of those who considered it important to receive support when suffering from fatigue and 23% of those who wanted to receive information on the expected course of their illness did not receive this or only did so sometimes. For most patients with advanced cancer, the palliative care that they receive matches what they consider important. Support for patients experiencing fatigue may need more attention. When symptoms are difficult to control, GPs and nurses may still provide emotional support and practical advice. Furthermore, we recommend that GPs discuss patients' need for information about the expected course of their illness.

In the new Affordable Care Act (ACA) health care environment, safety-net institutions continue to serve as important sources of culturally appropriate care for different groups of immigrant patients. This article reports on a qualitative study examining the early ACA enrollment experiences of a range of health care providers (n = 29) in six immigrant-serving safety-net clinics in New Mexico. The six clinics configured their ACA enrollment strategies differently with regard to operations, staffing, and outreach. Providers reported a generally chaotic rollout overall and expressed frustration with strategies that did not accommodate patients, provided little training for providers, and engaged in minimal outreach. Conversely, providers lauded strategies that flexibly met patient needs, leveraged trust through strategic use of staff, and prioritized outreach. Findings underscore the importance of using and funding concerted strategies for future enrollment of immigrant patients, such as featuring community health workers and leveraging trust for outreach.

The Economics of Comparative Effectiveness Studies

Comparative effectiveness research (CER) can provide valuable information for patients, providers and payers. These stakeholders differ in their incentives to invest in CER. To maximize benefits from public investments in CER, it is important to understand the value of CER from the perspectives of these stakeholders and how that affects their incentives to invest in CER. This article provides a conceptual framework for valuing CER, and illustrates the potential benefits of such studies from a number of perspectives using several case studies. We examine cases in which CER provides value by identifying when one treatment is consistently better than others, when different treatments are preferred for different subgroups, and when differences are small enough that decisions can be made based on price. We illustrate these findings using value-of-information techniques to assess the value of research, and by examining changes in pharmaceutical prices following publication of a comparative effectiveness study. Our results suggest that CER may have high societal value but limited private return to providers or payers. This suggests the importance of public efforts to promote the production of CER. We also conclude that value-of-information tools may help inform policy decisions about how much public funds to invest in CER and how to prioritize the use of available public funds for CER, in particular targeting public CER spending to areas where private incentives are low relative to social benefits.

Community-academic research partnerships aim to build stakeholder trust in order to improve the reach and translation of health research, but there is limited empirical research regarding effective ways to build trust. This multisite study was launched to identify similarities and differences among stakeholders' perspectives of antecedents to trust in research partnerships. In 2013-2014, we conducted a mixed-methods concept mapping study with participants from three major stakeholder groups who identified and rated the importance of different antecedents of trust on a 5-point Likert-type scale. Study participants were community members ( n = 66), health care providers ( n = 38), and academic researchers ( n = 44). All stakeholder groups rated "authentic communication" and "reciprocal relationships" the highest in importance. Community members rated "communication/methodology to resolve problems" ( M = 4.23, SD = 0.58) significantly higher than academic researchers ( M = 3.87, SD = 0.67) and health care providers ( M = 3.89, SD = 0.62; p < .01) and had different perspectives regarding the importance of issues related to "sustainability." The importance of communication and relationships across stakeholders indicates the importance of colearning processes that involve the exchange of knowledge and skills. The differences uncovered suggest specific areas where attention and skill building may be needed to improve trust within partnerships. More research on how partnerships can improve communication specific to problem solving and sustainability is merited.

An intervention to improve mental health care for conflict-affected forced migrants in low-resource primary care settings: a WHO MhGAP-based pilot study in Sri Lanka (COM-GAP study)

PubMed Central

2013-01-01

Background Inadequacy in mental health care in low and middle income countries has been an important contributor to the rising global burden of disease. The treatment gap is salient in resource-poor settings, especially when providing care for conflict-affected forced migrant populations. Primary care is often the only available service option for the majority of forced migrants, and integration of mental health into primary care is a difficult task. The proposed pilot study aims to explore the feasibility of integrating mental health care into primary care by providing training to primary care practitioners serving displaced populations, in order to improve identification, treatment, and referral of patients with common mental disorders via the World Health Organization Mental Health Gap Action Programme (mhGAP). Methods/Design This pilot randomized controlled trial will recruit 86 primary care practitioners (PCP) serving in the Puttalam and Mannar districts of Sri Lanka (with displaced and returning conflict-affected populations). The intervention arm will receive a structured training program based on the mhGAP intervention guide. Primary outcomes will be rates of correct identification, adequate management based on set criteria, and correct referrals of common mental disorders. A qualitative study exploring the attitudes, views, and perspectives of PCP on integrating mental health and primary care will be nested within the pilot study. An economic evaluation will be carried out by gathering service utilization information. Discussion In post-conflict Sri Lanka, an important need exists to provide adequate mental health care to conflict-affected internally displaced persons who are returning to their areas of origin after prolonged displacement. The proposed study will act as a local demonstration project, exploring the feasibility of formulating a larger-scale intervention study in the future, and is envisaged to provide information on engaging PCP, and data on training and evaluation including economic costs, patient recruitment, and acceptance and follow-up rates. The study should provide important information on the WHO mhGAP intervention guide to add to the growing evidence base of its implementation. Trial registration SLCTR/2013/025. PMID:24321171

2017-06-01

The Joint Commission on Accreditation of Healthcare Organizations specifically mandates the dual interpretation of musculoskeletal radiographs by a radiologist in addition to the orthopaedist in all hospital-based orthopaedic clinics. Previous studies have questioned the utility of this practice. The purpose of this study was to further investigate the clinical significance of having the radiologist provide a second interpretation in a hospital-based pediatric orthopaedic clinic. A retrospective review was performed of all patients who had plain radiographs obtained in the pediatric orthopaedic clinic at an academic children's hospital over a 4-month period. For each radiographic series, the orthopaedist's note and the radiology interpretation were reviewed and a determination was made of whether the radiology read provided new clinically useful information and/or a new diagnosis, whether it recommended further imaging, or if it missed a diagnosis that was reflected in the orthopaedist's note. The hospital charges associated with the radiology read for each study were also quantified. The charts of 1570 consecutive clinic patients who were seen in the pediatric orthopaedic clinic from January to April, 2012 were reviewed. There were 2509 radiographic studies performed, of which 2264 had both a documented orthopaedist's note and radiologist's read. The radiologist's interpretation added new, clinically important information in 1.0% (23/2264) of these studies. In 1.7% (38/2264) of the studies, it was determined that the radiologist missed the diagnosis or clinically important information that could affect treatment. The total amount of the professional fees charged for the radiologists' interpretations was $87,362. On average, the hospital charges for each occurrence in which the radiologist's read provided an additional diagnosis or clinically important information beyond the orthopaedist's note were $3798. The results of this study suggest that eliminating the requirement to have the radiologist interpret radiographs in the pediatric orthopaedic clinic would have few clinical consequences. Level III-This is a diagnostic retrospective cohort study.

To outline issues of importance to analytic approaches to the synthesis of quasi-experiments (QEs) and to provide a statistical model for use in analysis. We drew on studies of statistics, epidemiology, and social-science methodology to outline methods for synthesis of QE studies. The design and conduct of QEs, effect sizes from QEs, and moderator variables for the analysis of those effect sizes were discussed. Biases, confounding, design complexities, and comparisons across designs offer serious challenges to syntheses of QEs. Key components of meta-analyses of QEs were identified, including the aspects of QE study design to be coded and analyzed. Of utmost importance are the design and statistical controls implemented in the QEs. Such controls and any potential sources of bias and confounding must be modeled in analyses, along with aspects of the interventions and populations studied. Because of such controls, effect sizes from QEs are more complex than those from randomized experiments. A statistical meta-regression model that incorporates important features of the QEs under review was presented. Meta-analyses of QEs provide particular challenges, but thorough coding of intervention characteristics and study methods, along with careful analysis, should allow for sound inferences.

2017-05-01

Internal medicine residents are frequently called upon to provide palliative care to hospitalized patients, but report feeling unprepared to do so effectively. Curricular development to enhance residents' palliative care skills and competencies requires an understanding of current beliefs, attitudes and learning priorities. We conducted a qualitative study consisting of semi-structured interviews with ten internal medicine residents to explore their understanding of and experiences with palliative care. All of the residents interviewed had a sound theoretical understanding of palliative care, but faced many challenges in being able to provide care in practice. The challenges described by residents were system-related, patient-related and provider-related. They identified several priority areas for further learning, and discussed ways in which their current education in palliative care could be enhanced. Our findings provide important insights to guide curricular development for internal medicine trainees. The top five learning priorities in palliative care that residents identified in our study were: 1) knowing how and when to initiate a palliative approach, 2) improving communication skills, 3) improving symptom management skills, 4) identifying available resources, and 5) understanding the importance of palliative care. Residents felt that their education in palliative care could be improved by having a mandatory rotation in palliative care, more frequent didactic teaching sessions, more case-based teaching from palliative care providers, opportunities to be directly observed, and increased support from palliative care providers after-hours.

How the macroeconomic context impacts on attitudes to immigration: Evidence from within-country variation.

PubMed

Ruist, Joakim

2016-11-01

This study investigates the effects of the macroeconomic context on attitudes to immigration. Earlier studies do in some cases not provide significant empirical support for the existence of important such effects. In this article it is argued that this lack of consistent evidence is mainly due to the cross-national setup of these studies being vulnerable to estimation bias caused by country-specific factors. The present study instead analyzes attitude variation within countries over time. The results provide firm empirical support in favor of macroeconomic variation importantly affecting attitudes to immigration. As an illustration, the estimates indicate that the number of individuals in the average European country in 2012 who were against all immigration from poorer countries outside Europe was 40% higher than it would have been if macroeconomic conditions in that year had been as good as they were in 2006.

Impact of genomics on the understanding of microbial evolution and classification: the importance of Darwin's views on classification.

PubMed

Gupta, Radhey S

2016-07-01

Analyses of genome sequences, by some approaches, suggest that the widespread occurrence of horizontal gene transfers (HGTs) in prokaryotes disguises their evolutionary relationships and have led to questioning of the Darwinian model of evolution for prokaryotes. These inferences are critically examined in the light of comparative genome analysis, characteristic synapomorphies, phylogenetic trees and Darwin's views on examining evolutionary relationships. Genome sequences are enabling discovery of numerous molecular markers (synapomorphies) such as conserved signature indels (CSIs) and conserved signature proteins (CSPs), which are distinctive characteristics of different prokaryotic taxa. Based on these molecular markers, exhibiting high degree of specificity and predictive ability, numerous prokaryotic taxa of different ranks, currently identified based on the 16S rRNA gene trees, can now be reliably demarcated in molecular terms. Within all studied groups, multiple CSIs and CSPs have been identified for successive nested clades providing reliable information regarding their hierarchical relationships and these inferences are not affected by HGTs. These results strongly support Darwin's views on evolution and classification and supplement the current phylogenetic framework based on 16S rRNA in important respects. The identified molecular markers provide important means for developing novel diagnostics, therapeutics and for functional studies providing important insights regarding prokaryotic taxa. © FEMS 2016.

Peroxisomal biogenesis and function critically depends on the import of cytosolic proteins carrying a PTS1 sequence into this organelle upon interaction with the peroxin Pex5p. Recent structural studies have provided important insights into the molecular recognition of cargo proteins by Pex5p. Peroxisomal import is a key feature in the pathogenesis of primary hyperoxaluria type 1 (PH1), where alanine:glyoxylate aminotransferase (AGT) undergoes mitochondrial mistargeting in about a third of patients. Here, we study the molecular recognition of PTS1 cargo proteins by Pex5p using oligopeptides and AGT variants bearing different natural PTS1 sequences, and employing an array of biophysical, computational and cell biology techniques. Changes in affinity for Pex5p (spanning over 3-4 orders of magnitude) reflect different thermodynamic signatures, but overall bury similar amounts of molecular surface. Structure/energetic analyses provide information on the contribution of ancillary regions and the conformational changes induced in Pex5p and the PTS1 cargo upon complex formation. Pex5p stability in vitro is enhanced upon cargo binding according to their binding affinities. Moreover, we provide evidence that the rational modulation of the AGT: Pex5p binding affinity might be useful tools to investigate mistargeting and misfolding in PH1 by pulling the folding equilibria towards the native and peroxisomal import competent state.

Virioplankton are an important and abundant biological component of marine and freshwater ecosystems. Often overlooked, aquatic viruses play an important role in biogeochemical cycles on a global scale, infecting both autotrophic and heterotrophic microbes. Viral diversity, abundance, and viral interactions at different trophic levels in aqueous environments are not well understood. Tropical ecosystems are less frequently studied than temperate ecosystems, but could provide new insights into how physical and chemical variability can shape or force microbial community changes. In this study, we found high viral abundance values in Guanabara Bay relative to other estuaries around the world. Viral abundance was positively correlated with bacterioplankton abundance and chlorophyll a concentrations. Moreover, prokaryotic and viral abundance were positively correlated with eutrophication, especially in surface waters. These results provide novel baseline data on the quantitative distribution of aquatic viruses in tropical estuaries. They also provide new information on a complex and dynamic relationship in which environmental factors influence the abundance of bacterial hosts and consequently their viruses. Guanabara Bay is characterized by spatial and seasonal variations, and the eutrophication process is the most important factor explaining the structuring of virioplankton abundance and distribution in this tropical urbanized bay.

Identifying regions of the human genome that have been targets of positive selection will provide important insights into recent human evolutionary history and may facilitate the search for complex disease genes. However, the confounding effects of population demographic history and selection on patterns of genetic variation complicate inferences of selection when a small number of loci are studied. To this end, identifying outlier loci from empirical genome-wide distributions of genetic variation is a promising strategy to detect targets of selection. Here, we evaluate the power and efficiency of a simple outlier approach and describe a genome-wide scan for positive selection using a dense catalog of 1.58 million SNPs that were genotyped in three human populations. In total, we analyzed 14,589 genes, 385 of which possess patterns of genetic variation consistent with the hypothesis of positive selection. Furthermore, several extended genomic regions were found, spanning >500 kb, that contained multiple contiguous candidate selection genes. More generally, these data provide important practical insights into the limits of outlier approaches in genome-wide scans for selection, provide strong candidate selection genes to study in greater detail, and may have important implications for disease related research.

OBJECTIVE: To explore lesbian and bisexual women's experiences with their family physicians to learn about barriers to care and about how physicians can provide supportive care. DESIGN: Qualitative study that was part of a larger study of lesbian and bisexual women's health care. SETTING: The province of Nova Scotia, both urban and rural counties. PARTICIPANTS: Ninety-eight self-identified lesbian or bisexual women who volunteered through snowball sampling. Women were interviewed by lesbian, bisexual, or heterosexual female interviewers. METHOD: Semistructured, audiotaped, face-to-face interviews, exploring questions about demographic information, sexual orientation, general health care patterns, preferences for health care providers, disclosure issues, health care information, access issues, and important health care services. Transcription of audiotapes of interviews was followed by content, thematic, and discourse analyses. Thematic analysis is reported in this paper. MAIN OUTCOME FINDINGS: Three themes important for family physicians emerged: the importance of being gay positive, barriers to care, and strategies for providing appropriate care. CONCLUSIONS: Family physicians are in a pivotal position to ensure supportive care for lesbian and bisexual women. Physicians need to recognize barriers to care and to use gay-positive strategies, paying attention to self-education, health history, and clinic environment. PMID:9721419

2017-01-01

Presynaptic and postsynaptic neurotoxins are proteins which act at the presynaptic and postsynaptic membrane. Correctly predicting presynaptic and postsynaptic neurotoxins will provide important clues for drug-target discovery and drug design. In this study, we developed a theoretical method to discriminate presynaptic neurotoxins from postsynaptic neurotoxins. A strict and objective benchmark dataset was constructed to train and test our proposed model. The dipeptide composition was used to formulate neurotoxin samples. The analysis of variance (ANOVA) was proposed to find out the optimal feature set which can produce the maximum accuracy. In the jackknife cross-validation test, the overall accuracy of 94.9% was achieved. We believe that the proposed model will provide important information to study neurotoxins. PMID:28303250

In this study, the dosimetry community has a history of using spectral indices to support neutron spectrum characterization and cross section validation efforts. An important aspect to this type of analysis is the proper consideration of the contribution of the spectrum uncertainty to the total uncertainty in calculated spectral indices (SIs). This study identifies deficiencies in the traditional treatment of the SI uncertainty, provides simple bounds to the spectral component in the SI uncertainty estimates, verifies that these estimates are reflected in actual applications, details a methodology that rigorously captures the spectral contribution to the uncertainty in the SI, andmore » provides quantified examples that demonstrate the importance of the proper treatment the spectral contribution to the uncertainty in the SI.« less

There are diverse opinions and confusion about defining and including patient values and preferences (i.e. the importance people place on the health outcomes) in the guideline development processes. This article aims to provide an overview of a process for systematically incorporating values and preferences in guideline development. In 2013 and 2014, we followed the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to adopt, adapt and develop 226 recommendations in 22 guidelines for the Ministry of Health of the Kingdom of Saudi Arabia. To collect context-specific values and preferences for each recommendation, we performed systematic reviews, asked clinical experts to provide feedback according to their clinical experience, and consulted patient representatives. We found several types of studies addressing the importance of outcomes, including those reporting utilities, non-utility measures of health states based on structured questionnaires or scales, and qualitative studies. Guideline panels used the relative importance of outcomes based on values and preferences to weigh the balance of desirable and undesirable consequences of alternative intervention options. However, we found few studies addressing local values and preferences. Currently there are different but no firmly established processes for integrating patient values and preferences in healthcare decision-making of practice guideline development. With GRADE Evidence-to-Decision (EtD) frameworks, we provide an empirical strategy to find and incorporate values and preferences in guidelines by performing systematic reviews and eliciting information from guideline panel members and patient representatives. However, more research and practical guidance are needed on how to search for relevant studies and grey literature, assess the certainty of this evidence, and best summarize and present the findings.

2003-01-01

Public health researchers increasingly turn to qualitative methods either on their own or in combination with quantitative methods. Qualitative methods are especially important to community environmental health research, as they provide a way to produce community narratives that give voice to individuals and characterize the community in a full and complex fashion. This article first traces the legacy of qualitative research in environmental health, then uses a case study of the author's experiences studying the Woburn, Massachusetts, childhood leukemia cluster to provide personal and scholarly insights on qualitative approaches. That material then informs a discussion of important components of qualitative methods in environmental health research, including flexible study design, access, trust, empathy, and personal shifts in the researcher's worldview, bias, and the nature of the researcher's roles. A concluding discussion addresses issues in funding policy and research practices. PMID:14594634

In recent years, cognitive and educational psychologists have become interested in applying principles of cognitive psychology to education. Here, we discuss the importance of understanding the nature and occurrence of mind wandering in the context of classroom and online lectures. In reviewing the relevant literature, we begin by considering early studies that provide important clues about student attentiveness via dependent measures such as physical markers of inattention, note taking, and retention. We then provide a broad overview of studies that have directly measured mind wandering in the classroom and online learning environments. Finally, we conclude by discussing interventions that might be effective at curbing the occurrence of mind wandering in educational settings, and consider various avenues of future research that we believe can shed light on this well-known but little studied phenomenon.

Trust is widely recognised is a core feature of partnership relationships and one that facilitates joint work. It is an issue that must be addressed if partnerships are to enhance service system integration. In recent literature trust has been linked to concepts of risk and control. In this study of trust within a Primary Care Partnership (PCP) in Australia the experiences of risk and uncertainty, and control, of participants in different structural positions, were explored in detail. The data used in this paper was qualitative, derived from 63 interviews with managers and service providers participating in committees of the PCP. This paper reports on the differences in the experience of risk and uncertainty, trust and control, of managers and service providers working as boundary spanners through the committees of a PCP. For managers there were significant risks and uncertainties, and trust and control were important. For service providers there were few risks and uncertainties, and trust and control were of much less importance. Some policy implications of the differences in perspective are discussed, as are important areas for further research.

Menopause and the virtuous woman: the importance of the moral order in accounting for medical decision making.

2008-01-01

Whether or not to use hormone replacement therapy (HRT) around the time of menopause is seen as an important decision for many mid-aged women. Recent studies of information provided to women to assist them in making a medical decision about the use of HRT have highlighted the importance of understanding the broader social context of the decision. In this article we examine one important aspect of western mid-aged women's social world: the moral order and the imperative of virtue. Qualitative data from a survey, focus group discussions, and interviews with mid-aged women about HRT use are used to provide examples of the importance of the local moral order in women's talk about menopause and HRT use. The implications of these data will be discussed in terms of the different narrative resources available to construct menopause and HRT, the role of morality, and the demonstration of virtue in daily social life, including medical decision making.

Between 1995 and 2005, injectable use doubled worldwide. However, discontinuation rates remain high, partly because of side effects but also because of missed appointments for reinjection. A longer-acting injectable (LAI) may improve compliance by reducing the required number of reinjection visits, thereby reducing unintentional discontinuation. This study examined acceptability of LAI characteristics comprising the target product profile (TPP). In 2012, we conducted qualitative case studies in Kenya and Rwanda, consisting of 19 focus group discussions (FGDs) with 177 current, previous, or never users of injectables and 46 in-depth interviews (IDIs) with providers, program implementers, and policy makers. FGDs and IDIs assessed current injectable experiences; attitudes toward potential LAI products; and perceptions of TPP attributes, including ranking preferences for the most and least important characteristics. In addition, we obtained completed electronic surveys from 28 international family planning opinion leaders about the perceived need for an LAI, important product characteristics, and challenges to LAI development or introduction. Many FGD participants and interviewees spontaneously expressed strong interest in an LAI, but there was some variation in TPP preferences. The majority of participants ranked effectiveness as the most important TPP attribute. Providers were generally more concerned about side effects than potential users; some potential users suggested that side effects were related less to the product than to their own body chemistry and that side effects were acceptable as long as they did not last a long time or disrupt daily activities. Women and providers, especially in Kenya, preferred a method with a predictable return to fertility. Some participants associated amenorrhea with delayed or reduced fertility. Most women and providers preferred delivery of the LAI in a single, prepackaged, disposable injection system to facilitate injections by providers and to reduce the risk of pain or discomfort for women. While providers and policy makers ranked cost as one of the most important issues, it was among the least important issues for most potential users. Many Kenyan, but few Rwandan, participants appeared willing to pay for an LAI, with some presuming cost savings from reduced menstruation and fewer clinic visits. Some TPP preferences for an LAI have implications for product development decisions about formulation, delivery mechanism, or presentation, while others point to the need for tailored communication and counseling approaches to ensure acceptability and adherence within clinical trials and beyond.

Community–academic partnerships (CAPs) improve the research process, outcomes, and yield benefits for the community and researchers. This exploratory study examined factors important in community stakeholders’ decision to participate in CAPs. Autism spectrum disorder (ASD) community stakeholders, previously contacted to participate in a CAP (n = 18), completed the 15-item Decision to Participate Questionnaire (DPQ). The DPQ assessed reasons for participating or declining participation in the ASD CAP. CAP participants rated networking with other providers, fit of collaboration with agency philosophy, and opportunity for future training/consultations as factors more important in their decision to participate in the ASD CAP than nonparticipants. Nonparticipants reported the number of requests to participate in research as more important in their decision to decline participation than participants. Findings reveal important factors in community stakeholders’ decision to participate in CAPs that may provide guidance on increasing community engagement in CAPs and help close the science-to-service gap.

A pilot qualitative study to explore stakeholder opinions regarding prescribing quality indicators

2012-01-01

Background Information on prescribing quality of diabetes care is required by health care providers, insurance companies, policy makers, and the public. Knowledge regarding the opinions and preferences of all involved parties regarding prescribing quality information is important for effective use of prescribing quality indicators. Methods Between June and December 2009 we conducted semi structured interviews with 16 key-informants representing eight different organizations in the Netherlands involved in healthcare quality measurement and improvement. The interview guide included topics on participants’ opinions and preferences regarding existing types of prescribing quality indicators in relation to their aim of using quality information. Content analysis methods were used to process the resulting transcripts following the framework of predetermined themes. Results Findings from this qualitative study of stakeholder preferences showed that indicators focusing on undertreatment are found important by all participants. Furthermore, health care providers and policy makers valued prescribing safety indicators, insurance companies prioritized indicators focusing on prescribing costs, and patients’ organization representatives valued indicators focusing on interpersonal side of prescribing. Representatives of all stakeholders preferred positive formulation of the indicators to motivate health care providers to participate in health improvement programs. A composite score was found to be most useful by all participants as a starting point of prescribing quality assessment. Lack of information on reasons for deviating from guidelines recommendations appeared to be the most important barrier for using prescribing quality indicators. According to the health care providers, there are many legitimate reasons for not prescribing the recommended treatment and these reasons are not always taken into account by external evaluators. The latter may cause mistrust of health care providers towards external stakeholders and limit the use of PQI in external quality improvement programs. Conclusion Prescribing quality indicators are considered to be an important tool for assessing quality of provided diabetes care by all participants, although the preferences for specific types of indicators may differ by stakeholder depending on their user aim. Introduction of information systems to register the reasons for deviating from the recommended drug treatment may contribute to a more widespread use of PQI for assessment of provided health care quality to diabetic patents. This study identified the potential preferences regarding quality indicators for diabetes care, and this could be used for development of questionnaires to conduct a survey among a larger group of participants.

Poor terminological consistency for core concepts in implementation science has been widely noted as an obstacle to effective meta-analyses. This inconsistency is also a barrier for those seeking guidance from the research literature when developing and planning implementation initiatives. The Expert Recommendations for Implementing Change (ERIC) study aims to address one area of terminological inconsistency: discrete implementation strategies involving one process or action used to support a practice change. The present report is on the second stage of the ERIC project that focuses on providing initial validation of the compilation of 73 implementation strategies that were identified in the first phase. Purposive sampling was used to recruit a panel of experts in implementation science and clinical practice (N = 35). These key stakeholders used concept mapping sorting and rating activities to place the 73 implementation strategies into similar groups and to rate each strategy's relative importance and feasibility. Multidimensional scaling analysis provided a quantitative representation of the relationships among the strategies, all but one of which were found to be conceptually distinct from the others. Hierarchical cluster analysis supported organizing the 73 strategies into 9 categories. The ratings data reflect those strategies identified as the most important and feasible. This study provides initial validation of the implementation strategies within the ERIC compilation as being conceptually distinct. The categorization and strategy ratings of importance and feasibility may facilitate the search for, and selection of, strategies that are best suited for implementation efforts in a particular setting.

Combination prevention efforts are now recommended toward reducing HIV incidence among men who have sex with men (MSM). Understanding the perceptions of both MSM and service providers is critical to informing the development of prevention packages and ultimately improving intervention effectiveness. This study assessed the preferences of MSM and health service providers in the administration of HIV-prevention efforts. Qualitative data were gathered from a series of separate MSM and health care provider focus groups in 2 South African cities. Participants discussed HIV-prevention services and MSM client experiences within South Africa and identified the 3 most important clinic characteristics and 3 most important HIV-prevention services for MSM clients. Priorities indicated by both MSM and health care providers were confidentiality of visit, friendly staff, and condoms, while discrepancies existed between MSM and providers regarding provider consistency and the provision of pre-exposure prophylaxis/post-exposure prophylaxis (PrEP/PEP) and lubricant as prevention methods. Effective interventions must address these discrepancies through the design of intervention and provider training to optimally accommodate MSM.

Providing and seeking social support are important aspects of social exchange. New communication technologies, especially social network sites (SNSs), facilitate the process of support exchange. An increasing number of health organizations are using SNSs. However, how they provide and seek social support via SNSs has yet to garner academic attention. This study examined the types of social support provided and sought by health organizations on Twitter. A content analysis was conducted on 1,500 tweets sent by a random sample of 58 health organizations within 2 months. Findings indicate that providing informational and emotional support, as well as seeking instrumental support, were the main types of social support exchanged by health organizations through Twitter. This study provides a typology for studying social support exchanges by health organizations, and recommends strategies for health organizations regarding the effective use of Twitter.

The study was undertaken to identify factors affecting perception of the importance and practice of patient safety management (PSM) among hospital employees in Korea. This study was conducted using a descriptive design and a self-report questionnaire. Two hundred and eighty employees were recruited from three hospitals using a convenience sampling method. Measures were perception of the importance, practice, and characteristics of PSM. Data were analyzed using descriptive statistics including t test, one-way analysis of variance, Pearson's correlation analysis, and multiple regression. Factors affecting perception of the importance of PSM were whether hospital employees were in contact with patients while on duty, weekly working hours, education on PSM, and perceived adequacy of PSM system construction. Factors affecting the practice of PSM were perceived adequacy of work load, perceived adequacy of PSM system construction and perception of its importance. The findings of this study indicate a need for developing strategies to improve perception of the importance and practice of PSM among all hospital employees, and provide a reference for future experimental studies.

Johnson, D.H.

2002-01-01

Wildlife ecology and management studies have been widely criticized for deficiencies in design or analysis. Manipulative experiments--with controls, randomization, and replication in space and time--provide powerful ways of learning about natural systems and establishing causal relationships, but such studies are rare in our field. Observational studies and sample surveys are more common; they also require appropriate design and analysis. More important than the design and analysis of individual studies is metareplication: replication of entire studies. Similar conclusions obtained from studies of the same phenomenon conducted under widely differing conditions will give us greater confidence in the generality of those findings than would any single study, however well designed and executed.

Background The Medical Termination of Pregnancy (MTP) Act of 1971 liberalized abortion laws in India. This study examines changes in abortion service provision and characteristics of abortion providers in Bihar and Jharkhand states, India between 2004 and 2013. Methods We used state-representative data from cross-sectional surveys of reproductive health service providers we conducted in 2004 (N = 1,323) and 2012/2013 (N = 1,020). We employed chi-squared tests to examine and compare abortion providers’ characteristics, and fitted separate multivariate logistic regression models for provision of surgical, medical, and any abortion services, respectively, adjusting for potential confounders to identify factors associated with abortion service provision at the two survey time points. Results Of providers interviewed in 2004 and 2012/2013, 63.7% and 84.5%, respectively, offered abortion services. Among abortion providers, 21.1% offered surgical and 10.7% offered medical abortions in 2004; 15.8% and 94.1% did so, respectively, in 2012/2013. Private providers were more likely than public providers to offer abortion services at both time points. Compared to female providers, male providers were significantly less likely to provide both surgical and medical abortions in 2004, and significantly less likely to provide surgical abortions in 2012/2013. Pharmacists and community health workers played increasingly important roles in abortion service provision, especially medical abortion, during the period. Conclusion This study documents important changes in abortion provision in the two Indian states during 2004–2013. PMID:29879132

Understanding waterborne protozoan parasites (WPPs) diversity has important implications in public health. In this study, we evaluated a NGS-based method as a detection approach to identify simultaneously most important WPPs using 18S rRNA high-throughput sequencing. A set of primers to target the V4 18S rRNA region of WPPs such as Cryptosporidium spp., Giardia sp., Blastocystis sp., Entamoeba spp, Toxoplasma sp. and free-living amoebae (FLA) was designed. In order to optimize PCR conditions before sequencing, both a mock community with a defined composition of representative WPPs and a real water sample inoculated with specific WPPs DNA were prepared. Using the method proposed in this study, we have detected the presence of Giardia intestinalis, Acanthamoeba castellanii, Toxoplasma gondii, Entamoeba histolytica and Blastocystis sp. at species level in real irrigation water samples. Our results showed that untreated surface irrigation water in open fields can provide an important source of WPPs. Therefore, the methodology proposed in this study can establish a basis for an accurate and effective diagnostic of WPPs to provide a better understanding of the risk associated to irrigation water.

Why Are Omics Technologies Important to Understanding the Role of Nutrition in Inflammatory Bowel Diseases?

PubMed Central

Ferguson, Lynnette R.; Barnett, Matthew P. G.

2016-01-01

For many years, there has been confusion about the role that nutrition plays in inflammatory bowel diseases (IBD). It is apparent that good dietary advice for one individual may prove inappropriate for another. As with many diseases, genome-wide association studies across large collaborative groups have been important in revealing the role of genetics in IBD, with more than 200 genes associated with susceptibility to the disease. These associations provide clues to explain the differences in nutrient requirements among individuals. In addition to genes directly involved in the control of inflammation, a number of the associated genes play roles in modulating the gut microbiota. Cell line models enable the generation of hypotheses as to how various bioactive dietary components might be especially beneficial for certain genetic groups. Animal models are necessary to mimic aspects of the complex aetiology of IBD, and provide an important link between tissue culture studies and human trials. Once we are sufficiently confident of our hypotheses, we can then take modified diets to an IBD population that is stratified according to genotype. Studies in IBD patients fed a Mediterranean-style diet have been important in validating our hypotheses and as a proof-of-principle for the application of these sensitive omics technologies to aiding in the control of IBD symptoms.

Kernel-Based Measure of Variable Importance for Genetic Association Studies.

PubMed

Gallego, Vicente; Luz Calle, M; Oller, Ramon

2017-06-17

The identification of genetic variants that are associated with disease risk is an important goal of genetic association studies. Standard approaches perform univariate analysis where each genetic variant, usually Single Nucleotide Polymorphisms (SNPs), is tested for association with disease status. Though many genetic variants have been identified and validated so far using this univariate approach, for most complex diseases a large part of their genetic component is still unknown, the so called missing heritability. We propose a Kernel-based measure of variable importance (KVI) that provides the contribution of a SNP, or a group of SNPs, to the joint genetic effect of a set of genetic variants. KVI can be used for ranking genetic markers individually, sets of markers that form blocks of linkage disequilibrium or sets of genetic variants that lie in a gene or a genetic pathway. We prove that, unlike the univariate analysis, KVI captures the relationship with other genetic variants in the analysis, even when measured at the individual level for each genetic variable separately. This is specially relevant and powerful for detecting genetic interactions. We illustrate the results with data from an Alzheimer's disease study and show through simulations that the rankings based on KVI improve those rankings based on two measures of importance provided by the Random Forest. We also prove with a simulation study that KVI is very powerful for detecting genetic interactions.

Phylogenetic relationships among blowfly (Calliphoridae) species of forensic importance are explored using DNA sequence data from the large sub-unit (lsu, 28S) ribosomal RNA (rRNA) gene, the study includes representatives of a range of calliphorid species commonly encountered in forensic analysis in Britain and Europe. The data presented provide a basis to define molecular markers, including the identification of highly informative intra-sequence regions, which may be of use in the identification of larvae for forensic entomology. Phylogenetic analysis of the sequences also provides new insights into the different evolutionary patterns apparent within the family Calliphoridae which, additionally, can provide a measure of the degree of genetic variation likely to be encountered within taxonomic groups of differing forensic utility.

A Phenomenological Study of the Office Environments of Clinical Social Workers.

Jones, Jamie K

The purpose of this study was to explore the meaning and uses of the office space among licensed clinical social workers in private practice. Previous research suggests the importance of the office space in clinical practice in regard to therapeutic alliance, client behavior, and the well-being of the therapist. However, therapist offices contain much variation in design. This study looked further into specifically how the therapy room is important through the perspective of the licensed clinical social workers in order to identify common themes. Seven licensed clinical social workers in private psychotherapy practice were interviewed in their offices. Phenomenological research methods were used to explore and analyze their experiences. While the offices contained many physical differences, the intentions behind the designs were similar. Three themes emerged regarding how participants used and designed their spaces. First, participants used their offices to provide care for clients and themselves. Second, participants used their spaces to communicate therapeutic messages and to reveal and/or conceal aspects of themselves. Third, participants also used their space in direct practice. This phenomenological study provided insight into the importance and use of the psychotherapy office space. These findings may be helpful for therapists designing or redesigning their own practice spaces.

To use a Delphi panel to determine the relative importance and feasibility of workplace health promotion interventions to promote and support the health of the Australian nursing and midwifery workforce. The nursing workforce experiences rates of ill health above that of other workforces, yet there is little investment in workplace health promotion. The study used a modified Delphi design conducted between September and November 2015. Eleven of 19 purposively selected expert panellists discussed, rated and provided feedback through two rounds of an electronic questionnaire about the relative importance and feasibility of 46 workplace health promotion interventions and processes for nurses and midwives. Scores for importance and feasibility were calculated and ranked and a composite score of importance multiplied by feasibility. Mental health strategies were prioritized as the most important and feasible of the intervention topics, followed closely by healthy eating and physical activity interventions; smoking cessation ranked lowest. The most highly ranked interventions targeted healthy eating, stress management and resilience training. Highest ranked processes to support development of a healthy work environment included intersectoral collaboration and employee wellness groups. Study findings prompt consideration of health promotion opportunities to support nurses' health and well-being. Findings identified key workplace health promotion priorities and provide direction for policy makers and managers to promote nursing and midwifery workforce health. © 2017 John Wiley & Sons Ltd.

Base Excision Repair Variants in Cancer

PubMed Central

Marsden, Carolyn G.; Dragon, Julie A.; Wallace, Susan S.; Sweasy, Joann B.

2018-01-01

Base excision repair (BER) is a key genome maintenance pathway that removes endogenously damaged DNA bases that arise in cells at very high levels on a daily basis. Failure to remove these damaged DNA bases leads to increased levels of mutagenesis and chromosomal instability, which have the potential to drive carcinogenesis. Next Generation sequencing efforts of the germline and tumors genomes of thousands of individuals has uncovered many rare mutations in BER genes. Given that BER is critical for genome maintenance, it is important to determine whether BER genomic variants have functional phenotypes. In this chapter we present our in silico methods for the identification and prioritization of BER variants for further study. We also provide detailed instructions and commentary on the initial cellular assays we employ to dissect potentially important phenotypes of human BER variants and highlight the strengths and weaknesses of our approaches. BER variants possessing interesting functional phenotypes can then be studied in more detail to provide important mechanistic insights regarding the role of aberrant BER in carcinogenesis.

The purpose of this study was to construct the quality indicators of professional competence for exercise instructors of the elderly, and then to rank the importance among those indicators. This study used the Delphi technique to integrate the opinions of 11 experts to construct the indicators, and then adopts the analytic hierarchy process (AHP) to calculate the relative rank among each individual indicator. Results revealed that the experts identified 3 first-degree indicators (professional attitude, professional skills, and professional knowledge), 10 second-degree indicators (teaching attitude, exercise knowledge, professional growth, exercise safety, personal characteristics, exercise instructor, gerontology knowledge, communicative competence, curriculum design, and motor skill), and 72 third-degree indicators. In the indicator weighting system, professional attitude was the most important among all other first-degree indicators, and the teaching attitude was the most important among all other second-degree indicators. The results provided will help in planning the curriculums of training, professional growth and evaluation. The results also provide a reference for future research.

Healy, C Mary; Montesinos, Diana P; Middleman, Amy B

2014-01-23

Data are limited on whether providers understand parental attitudes to recommended childhood immunizations. We determined parental attitudes and assessed how accurately providers estimated parental opinions. Survey of parents and providers (pediatricians, nurses, medical assistants) in randomly selected practices in Houston, Texas. Surveys assessed demographics, perceptions of immunization importance, safety and efficacy, and acceptability of vaccine delivery. Providers estimated parental responses. 401 parents (82% mothers, 12% fathers, 6% other) and 105 providers participated. Parents thought vaccines were important for health (median score 9.5; 0=not important, 10=extremely important) but also were concerned regarding vaccine safety and side effects (8.9 on 0-10 scale). 309 (77%) agreed that vaccines effectively prevent disease. Route of administration mattered to 147 (37%), who preferred injection (9.0) over oral (7.3) or intranasal (4.8) routes. Although parents would prefer three or fewer injections per visit, preventing more diseases (189 [47.6%]) was more important than number of injections (167 [42.3%]) when deciding the number of vaccines allowed per visit. White parents rated vaccines less important in preventing some illnesses than did non-white (P≤0.006 for meningitis, hepatitis, HPV, influenza and rotavirus) and rated number of injections per visit more important than number of diseases prevented (51.6% white versus 34.2% non-white; P 0.002). Providers underestimated parental attitudes toward vaccine importance (particularly influenza and HPV), and overestimated the proportion of parents who thought route of administration mattered (63%) and that number of injections per visit was the most important factor (76%) around parental vaccine decisions (P<0.001 for parent-provider mismatch). Most surveyed parents believe vaccines are important for child health and rate disease prevention higher than number of injections entailed. Providers underestimate the importance of some vaccines to parents and overestimate parental concerns regarding route of administration. Future research should focus on how this mismatch impacts parental vaccine decisions. Copyright © 2013 Elsevier Ltd. All rights reserved.

Observational Studies: Cohort and Case-Control Studies

2010-01-01

Observational studies are an important category of study designs. To address some investigative questions in plastic surgery, randomized controlled trials are not always indicated or ethical to conduct. Instead, observational studies may be the next best method to address these types of questions. Well-designed observational studies have been shown to provide results similar to randomized controlled trials, challenging the belief that observational studies are second-rate. Cohort studies and case-control studies are two primary types of observational studies that aid in evaluating associations between diseases and exposures. In this review article, we describe these study designs, methodological issues, and provide examples from the plastic surgery literature. PMID:20697313

Purpose Measuring healthcare service quality provides an objective guide for managers and policy makers to improve their services and patient satisfaction. Consequently, the purpose of this paper is to measure service quality provided to surgical and medical inpatients at Kerman Medical Sciences University (KUMS) in 2015. Design/methodology/approach A descriptive-analytic study, using a cross-sectional method in the KUMS training hospitals, was implemented between October 2 and March 15, 2015. Using stratified random sampling, 268 patients were selected. Data were collected using an importance-performance analysis (IPA) questionnaire, which measures current performance and determines each item's importance from the patients' perspectives. These data indicate overall satisfaction and appropriate practical strategies for managers to plan accordingly. Findings Findings revealed a significant gap between service importance and performance. From the patients' viewpoint, tangibility was the highest priority (mean=3.54), while reliability was given the highest performance (mean=3.02). The least important and lowest performance level was social accountability (mean=1.91 and 1.98, respectively). Practical implications Healthcare managers should focus on patient viewpoints and apply patient comments to solve problems, improve service quality and patient satisfaction. Originality/value The authors applied an IPA questionnaire to measure service quality provided to surgical and medical ward patients. This method identifies and corrects service quality shortcomings and improving service recipient perceptions.

Lead and uranium group abundances in cosmic rays

The importance of Lead and Uranium group abundances in cosmic rays is discussed in understanding their evolution and propagation. The electronic detectors can provide good charge resolution but poor data statistics. The plastic detectors can provide somewhat better statistics but charge resolution deteriorates. The extraterrestrial crystals can provide good statistics but with poor charge resolution. Recent studies of extraterrestrial crystals regarding their calibration to accelerated uranium ion beam and track etch kinetics are discussed. It is hoped that a charge resolution of two charge units can be achieved provided an additional parameter is taken into account. The prospects to study abundances of Lead group, Uranium group and superheavy element in extraterrestrial crystals are discussed, and usefulness of these studies in the light of studies with electronic and plastic detectors is assessed.

Provision of community-wide benefits in public health intervention research: the experience of investigators conducting research in the community setting in South Asia.

Taylor, Holly A; Merritt, Maria W

2012-12-01

This article describes the types of community-wide benefits provided by investigators conducting public health research in South Asia as well as their self-reported reasons for providing such benefits. We conducted 52 in-depth interviews to explore how public health investigators in low-resource settings make decisions about the delivery of ancillary care to research subjects. In 39 of the interviews respondents described providing benefits to members of the community in which they conducted their study. We returned to our narrative dataset to find answers to two questions: What types of community-wide benefits do researchers provide when conducting public health intervention studies in the community setting, and what reasons do researchers give when asked why they provided community-wide benefits? The types of community-wide benefits delivered were directed to the health and well-being of the population. The most common types of benefits delivered were the facilitation of access to health care for individuals in acute medical need and emergency response to natural disasters. Respondents' self-reported reasons when asked why they provided such benefits fell into 2 general categories: intrinsic importance and instrumental importance. © 2012 Blackwell Publishing Ltd.

Integrating advanced practice providers into medical critical care teams.

PubMed

McCarthy, Christine; O'Rourke, Nancy C; Madison, J Mark

2013-03-01

Because there is increasing demand for critical care providers in the United States, many medical ICUs for adults have begun to integrate nurse practitioners and physician assistants into their medical teams. Studies suggest that such advanced practice providers (APPs), when appropriately trained in acute care, can be highly effective in helping to deliver high-quality medical critical care and can be important elements of teams with multiple providers, including those with medical house staff. One aspect of building an integrated team is a practice model that features appropriate coding and billing of services by all providers. Therefore, it is important to understand an APP's scope of practice, when they are qualified for reimbursement, and how they may appropriately coordinate coding and billing with other team providers. In particular, understanding when and how to appropriately code for critical care services (Current Procedural Terminology [CPT] code 99291, critical care, evaluation and management of the critically ill or critically injured patient, first 30-74 min; CPT code 99292, critical care, each additional 30 min) and procedures is vital for creating a sustainable program. Because APPs will likely play a growing role in medical critical care units in the future, more studies are needed to compare different practice models and to determine the best way to deploy this talent in specific ICU settings.

The first near-infrared reflectance spectrum of an exoplanet

NASA Astrophysics Data System (ADS)

Desert, Jean-Michel

2017-08-01

Amongst the important results that came out in the field of exoplanetology is that clouds and hazes in exoplanet atmospheres seem to be ubiquitous. Their presence provides important information on the chemistry and composition of atmospheres, and have major impact on planets' energy budgets and evolutions. Aerosols are also important observationally because they prevent probing deeper atmospheric composition, and they have been the common interpretation in a long list of published featureless transmission spectra. However, none of these indirect detections can definitely confirm or deny the presence of aerosols; thus, we propose a program that will change our view on aerosols by looking at their reflectivity.Theoretical models and laboratory experiments have long speculated on the origins and properties of aerosols in exoplanet atmospheres. More recent studies have shown that photochemical hazes can be very reflective in the near-Infrared (NIR) for planets cooler than 900 K. We propose to tackle this revolutionizing idea by pioneering an observational program that will both test these new models and provide a novel way to study atmospheres of exoplanets.We will look for reflective hazes in the NIR with WFC3 and deliver the first geometric albedo spectrum (Ag) of an exoplanet: WASP-80b. We will measure expected reflectivity (Ag=0.5) at high level of confidence (7-Sigma), and put stringent limits on haze models. This program will provide a pathway towards the study of exoplanets around low mass-stars through their reflectivity, which is urgent since these will be the golden targets for JWST. Only HST can provide the required precision for such an experiment.

"I've got somebody there, someone cares": what support is most valued following a stroke?

PubMed

Northcott, Sarah; Hilari, Katerina

2017-06-19

There is often a need for increased support following a stroke. This study explored what types of support are provided by different network members and what support functions are most valued. Adults with first stroke were recruited from a stroke unit and participated in in-depth interviews 8-15 months poststroke. Framework Analysis was used to build thematic and explanatory accounts of the data. Twenty-nine participants took part. Main themes to emerge were as follows: the spouse was the most important provider of support; children were a relatively stable source of support, although many participants expressed reservations about worrying a child; relatives and friends typically provided social companionship and emotional support rather than on-going practical support. The only universally valued support function was the sense that someone was concerned and cared. Other valued functions were as follows: social companionship including everyday social "chit chat"; practical support provided sensitively; and, for many, sharing worries and sensitive encouragement. The manner and context in which support was provided was important: support was easiest to receive when it communicated concern, and was part of a reciprocal, caring relationship. As well as measuring supportive acts, researchers and clinicians should consider the manner and context of support. Implications for rehabilitation The manner in which support was provided mattered: support was easier to receive when it communicated concern. The spouse was the most important source of all support functions; children, relatives and friends were important providers of emotional and social companionship support. Researchers and clinicians should not only focus on what support is received, but also the context (e.g., contribution, reciprocity, quality of relationship) and manner (e.g., responsiveness, sensitivity) of the support.

Laboratory animal studies are used in a wide range of human health related research areas, such as basic biomedical research, drug research, experimental surgery and environmental health. The results of these studies can be used to inform decisions regarding clinical research in humans, for example the decision to proceed to clinical trials. If the research question relates to potential harms with no expectation of benefit (e.g., toxicology), studies in experimental animals may provide the only relevant or controlled data and directly inform clinical management decisions. Systematic reviews and meta-analyses are important tools to provide robust and informative evidence summaries of these animal studies. Rating how certain we are about the evidence could provide important information about the translational probability of findings in experimental animal studies to clinical practice and probably improve it. Evidence summaries and certainty in the evidence ratings could also be used (1) to support selection of interventions with best therapeutic potential to be tested in clinical trials, (2) to justify a regulatory decision limiting human exposure (to drug or toxin), or to (3) support decisions on the utility of further animal experiments. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach is the most widely used framework to rate the certainty in the evidence and strength of health care recommendations. Here we present how the GRADE approach could be used to rate the certainty in the evidence of preclinical animal studies in the context of therapeutic interventions. We also discuss the methodological challenges that we identified, and for which further work is needed. Examples are defining the importance of consistency within and across animal species and using GRADE’s indirectness domain as a tool to predict translation from animal models to humans.

Estimation of the protein content of US imports of milk protein concentrates.

PubMed

Bailey, K W

2003-12-01

Recent declines in milk prices in the United States have sparked renewed concern that imports of milk protein concentrates (MPC) are increasingly entering the United States with very low tariff rates and is having an adverse impact on the US dairy industry. Milk protein concentrates are used in the United States in many different products, including the starter culture of cheese, or in nonstandard cheeses such as baker's cheese, ricotta, Feta and Hispanic cheese, processed cheese foods, and nutritional products. One of the difficult aspects of trying to assess the impact of MPC imports on the US dairy industry is to quantify the protein content of these imports. The protein content of MPC imports typically ranges from 40 to 88%. The purpose of this study is to develop a methodology that can be used to estimate the protein content of MPC on a country by country basis. Such an estimate would not only provide information regarding the quantity of protein entering the United States, but would also provide a profile of low- and high-value MPC importers. This is critical for market analysis, since it is the lower valued MPC imports that more directly displaces US-produced skim milk powder.

Calculating and reporting effect sizes to facilitate cumulative science: a practical primer for t-tests and ANOVAs

PubMed Central

Lakens, Daniël

2013-01-01

Effect sizes are the most important outcome of empirical studies. Most articles on effect sizes highlight their importance to communicate the practical significance of results. For scientists themselves, effect sizes are most useful because they facilitate cumulative science. Effect sizes can be used to determine the sample size for follow-up studies, or examining effects across studies. This article aims to provide a practical primer on how to calculate and report effect sizes for t-tests and ANOVA's such that effect sizes can be used in a-priori power analyses and meta-analyses. Whereas many articles about effect sizes focus on between-subjects designs and address within-subjects designs only briefly, I provide a detailed overview of the similarities and differences between within- and between-subjects designs. I suggest that some research questions in experimental psychology examine inherently intra-individual effects, which makes effect sizes that incorporate the correlation between measures the best summary of the results. Finally, a supplementary spreadsheet is provided to make it as easy as possible for researchers to incorporate effect size calculations into their workflow. PMID:24324449

This paper reports on a case study of the teacher's role as facilitator in computer-supported collaborative learning (CSCL) settings in science. In naturalistic classroom settings, the teacher most often acts as an important resource and provides various forms of guidance during students' learning activities. Few studies, however, have focused on the role of teacher intervention in CSCL settings. By analyzing the interactions between secondary school students and their teacher during a science project, the current study provides insight into the concerns that teachers might encounter when facilitating students' learning processes in these types of settings. The analyses show that one main concern was creating a balance between providing the requested information and supporting students in utilizing each other's knowledge and understanding. Another concern was balancing support on an individual versus group level, and a third concern was directing the students' attention to coexisting conceptual perspectives. Most importantly, however, the analyses show how teacher intervention constitutes the pivotal "glue" that aids students in linking and using coexisting aspects of support such as peer collaboration, digital tools, and instructional design.

Research into the key themes and concepts of quality of life (QOL) relevant to the end-of-life (EOL) care of pediatric cancer patients in the Japanese context is imperative. This study aimed at identifying the key items and constructive concepts of QOL at EOL of pediatric cancer patients. In 2015, pediatricians and nurses were recruited from 163 pediatric oncology treatment facilities in Japan. The questionnaire was developed on the basis of a previous qualitative study. Items that were rated as "very important" or "important" by at least 80% of the respondents were considered as "common and important" QOL items. Exploratory factor analysis was performed to conceptualize QOL of the pediatric cancer patients during EOL care. A total of 157 pediatricians and 270 nurses participated in this study. Fifty-five items were refined to 35 "common and important" QOL items. On factor analysis, 12 domains (containing 29 items) were identified: playing and learning; fulfilling wishes; spending time with family; receiving relief from physical and psychological suffering; making many wonderful memories; having a good relationship with the medical staff; having a peaceful death in the presence of family; spending time with a minimum of medical treatment; living one's life as usual; spending time in a calm hospital environment; being oneself; and having a close family. Although the respondents in this study were medical care providers rather than the patients or their family members, findings should help medical staff provide better palliative care to Japanese pediatric cancer patients.

The mouth and teeth play an important role in social interactions around the world. The way people deal with their teeth and mouth, however, is determined culturally. When oral healthcare projects are being carried out in developing countries, differing cultural worldviews can cause misunderstandings between oral healthcare providers and their patients. The oral healthcare volunteer often has to try to understand the local assumptions about teeth and oral hygiene first, before he or she can bring about a change of behaviour, increase therapy compliance and make the oral healthcare project sustainable. Anthropology can be helpful in this respect. In 2014, in a pilot project commissioned by the Dutch Dental Care Foundation, in which oral healthcare was provided in combination with anthropological research, an oral healthcare project in Kwale (Kenia) was evaluated. The study identified 6 primary themes that indicate the most important factors influencing the oral health of school children in Kwale. Research into the local culture by oral healthcare providers would appear to be an important prerequisite to meaningful work in developing countries.

An important factor in controlling diabetes is self-monitoring of blood glucose. Manufacturers of glucose meters recommend routine use of control solution to ensure accuracy. Previous studies have demonstrated that glucose meters vary in accuracy and that patients are not using control solution as recommended. The purpose of this study is to identify potential barriers to control solution use from multiple perspectives including patient, pharmacist, and provider. This study was a prospective, observational survey design. First, 25 randomly selected chain and independent pharmacies in the Tulsa metropolitan area were audited for control solution accessibility. These pharmacies were then used to survey pharmacists, via telephone, regarding control solution inventory and perception of importance of use. Next, providers were electronically surveyed on their routine practice recommendations, while 60 patients with diabetes were randomly selected for telephone survey on use and perceptions of control solution. Twenty-five pharmacies were audited and 23 pharmacists, 60 patients, and 29 providers were surveyed. Only 39% of pharmacies stated they supplied control solution, however, only 1 pharmacy visibly stocked it. The only patient factor that appeared to have an impact on control solution usage was having type 1 versus type 2 diabetes (38% vs 15%). Providers are aware of what control solution is (62%), but only half felt it should be routine practice with 44% of those never recommending it. This study raises awareness for the need to educate patients, providers, and pharmacists about use of control solution to ensure glucose meter accuracy.

Background Although the importance of detecting, treating, and controlling hypertension has been recognized for decades, the majority of patients with hypertension remain uncontrolled. The path from evidence to practice contains many potential barriers, but their role has not been reviewed systematically. This review aimed to synthesize and identify important barriers to hypertension control as reported by patients and healthcare providers. Methods Electronic databases MEDLINE, EMBASE and Global Health were searched systematically up to February 2013. Two reviewers independently selected eligible studies. Two reviewers categorized barriers based on a theoretical framework of behavior change. The theoretical framework suggests that a change in behavior requires a strong commitment to change [intention], the necessary skills and abilities to adopt the behavior [capability], and an absence of health system and support constraints. Findings Twenty-five qualitative studies and 44 quantitative studies met the inclusion criteria. In qualitative studies, health system barriers were most commonly discussed in studies of patients and health care providers. Quantitative studies identified disagreement with clinical recommendations as the most common barrier among health care providers. Quantitative studies of patients yielded different results: lack of knowledge was the most common barrier to hypertension awareness. Stress, anxiety and depression were most commonly reported as barriers that hindered or delayed adoption of a healthier lifestyle. In terms of hypertension treatment adherence, patients mostly reported forgetting to take their medication. Finally, priority setting barriers were most commonly reported by patients in terms of following up with their health care providers. Conclusions This review identified a wide range of barriers facing patients and health care providers pursuing hypertension control, indicating the need for targeted multi-faceted interventions. More methodologically rigorous studies that encompass the range of barriers and that include low- and middle-income countries are required in order to inform policies to improve hypertension control.

2016-01-01

Background: Preventive care is an important part of primary care medicine, yet much variation in its practice exists. The aim of this study is to assess physicians’ perspectives of practicing preventive medicine and evaluate which topics are deemed most important. Methods: All primary care medicine providers at two separate academic medical centers (Mayo Clinic, MN and Mayo Clinic, FL) were surveyed via an E-mail questionnaire assessing physicians’ perception of the role of preventive medicine during both acute/routine and yearly visits, physicians’ perception of patients’ response to preventive medicine topics, and which preventive medicine topics are commonly practiced. Results: Of 445 providers meeting inclusion criteria, a total of 183 (41.1%) responded. Providers were more likely to engage patients in preventive medicine during yearly visits more so than acute visits (3.82 vs. 4.72, range 1–5 Likert Scale), yet providers were very likely to partake in such practices during both visits. Providers perceived that patients received the practice of preventive medicine very well (4.13 on 1–5 Likert Scale). No significant difference between provider practice and patient perception was noted between the two sites, although there was some variation based on clinical experience of the provider. Providers were found to most commonly practice topics recommended by the United States Preventive Services Task Force. Conclusions: Our study found a high predisposition to practicing preventive medicine. Providers seem to practice according to published evidence-based medicine recommendations. PMID:26941906

Exploring How Lay Rescuers Overcome Barriers to Provide Cardiopulmonary Resuscitation: A Qualitative Study.

Survival rates after out-of-hospital cardiac arrest (OHCA) vary considerably among regions. The chance of survival is increased significantly by lay rescuer cardiopulmonary resuscitation (CPR) before Emergency Medical Services (EMS) arrival. It is well known that for bystanders, reasons for not providing CPR when witnessing an OHCA incident may be fear and the feeling of being exposed to risk. The aim of this study was to gain a better understanding of why barriers to providing CPR are overcome. Using a semi-structured interview guide, 10 lay rescuers were interviewed after participating in eight OHCA incidents. Qualitative content analysis was used. The lay rescuers were questioned about their CPR-knowledge, expectations, and reactions to the EMS and from others involved in the OHCA incident. They also were questioned about attitudes towards providing CPR in an OHCA incident in different contexts. The lay rescuers reported that they were prepared to provide CPR to anybody, anywhere. Comprehending the severity in the OHCA incident, both trained and untrained lay rescuers provided CPR. They considered CPR provision to be the expected behavior of any community citizen and the EMS to act professionally and urgently. However, when asked to imagine an OHCA in an unclear setting, they revealed hesitation about providing CPR because of risk to their own safety. Mutual trust between community citizens and towards social institutions may be reasons for overcoming barriers in providing CPR by lay rescuers. A normative obligation to act, regardless of CPR training and, importantly, without facing any adverse legal reactions, also seems to be an important factor behind CPR provision.

The economics of comparative effectiveness studies: societal and private perspectives and their implications for prioritizing public investments in comparative effectiveness research.

Comparative effectiveness research (CER) can provide valuable information for patients, providers and payers. These stakeholders differ in their incentives to invest in CER. To maximize benefits from public investments in CER, it is important to understand the value of CER from the perspectives of these stakeholders and how that affects their incentives to invest in CER. This article provides a conceptual framework for valuing CER, and illustrates the potential benefits of such studies from a number of perspectives using several case studies. We examine cases in which CER provides value by identifying when one treatment is consistently better than others, when different treatments are preferred for different subgroups, and when differences are small enough that decisions can be made based on price. We illustrate these findings using value-of-information techniques to assess the value of research, and by examining changes in pharmaceutical prices following publication of a comparative effectiveness study. Our results suggest that CER may have high societal value but limited private return to providers or payers. This suggests the importance of public efforts to promote the production of CER. We also conclude that value-of-information tools may help inform policy decisions about how much public funds to invest in CER and how to prioritize the use of available public funds for CER, in particular targeting public CER spending to areas where private incentives are low relative to social benefits.

Polyploidy: adaptation to the genomic environment.

PubMed

Hollister, Jesse D

2015-02-01

Genomic evidence of ancestral whole genome duplication (WGD) and polyploidy is widespread among eukaryotic species, and especially among plants. WGD is thought to provide the raw material for adaptation in the form of duplicated genes, and polyploids are thought to benefit from both physiological and genetic buffering. Comparatively little attention has focused on the genomic challenge of polyploidy, however, although much evidence exists that polyploidy severely perturbs important cellular functions. Here, I review recent progress in the study of the re-establishment of stable meiosis in recently evolved polyploids, focusing on four plant species. This work has yielded an insight into the mechanisms underlying stabilization of genome transmission in polyploids, and is revealing remarkable parallels among diverse taxa. Importantly, these studies also provide a road map for investigating how polyploids respond to the challenge of WGD.

The study of population change with regard to reproduction, seed dispersal, and germination, establishment, growth, and survival/mortality is known as demography. Demographic studies provide managers with information to assess future trends on the density, distribution, health, and population changes of importance or value, including Joshua trees (Yucca brevifolia). Demographic research provides the potential to understand the combined impacts of climate change and land-use practices and determine if strategies for protecting important species are likely to succeed or fall short of management goals and will identify factors that have the potential to de-stabilize populations outside the realm of natural variation so that management strategies can be developed to circumvent challenges for key species, processes, and ecosystems. The National Park Service and US Geological Survey are collaborating to collect demographic information about the demographics of Joshua tree in the Mojave Desert.

This paper provides a map of the scientific productivity of authors affiliated to a Spanish institution and who have addressed one of the most important current topics in schizophrenia: The study of cognitive performance. A search of the Web of Science yielded 125 articles that met the inclusion criteria. In order to provide a comprehensive overview of scientific productivity, we examine several bibliometric indicators, concerning both productivity and impact or visibility. The analysis also focuses on qualitative aspects of key theoretical importance, such as the kinds of cognitive functions that are most often assessed and the tests most widely used to evaluate them in clinical practice. The study shows that interest in the subject of cognitive function in schizophrenia has increased considerably in Spain since the beginning of this century. The results also highlight the need to standardize the type of tests to be used in the cognitive assessment of patients with schizophrenia.

Integrated approach for quantification of fractured tight reservoir rocks: Porosity, permeability analyses and 3D fracture network characterisation on fractured dolomite samples

NASA Astrophysics Data System (ADS)

Voorn, Maarten; Barnhoorn, Auke; Exner, Ulrike; Baud, Patrick; Reuschlé, Thierry

2015-04-01

Fractured reservoir rocks make up an important part of the hydrocarbon reservoirs worldwide. A detailed analysis of fractures and fracture networks in reservoir rock samples is thus essential to determine the potential of these fractured reservoirs. However, common analyses on drill core and plug samples taken from such reservoirs (including hand specimen analysis, thin section analysis and laboratory porosity and permeability determination) suffer from various problems, such as having a limited resolution, providing only 2D and no internal structure information, being destructive on the samples and/or not being representative for full fracture networks. In this study, we therefore explore the use of an additional method - non-destructive 3D X-ray micro-Computed Tomography (μCT) - to obtain more information on such fractured samples. Seven plug-sized samples were selected from narrowly fractured rocks of the Hauptdolomit formation, taken from wellbores in the Vienna Basin, Austria. These samples span a range of different fault rocks in a fault zone interpretation, from damage zone to fault core. 3D μCT data is used to extract porosity, fracture aperture, fracture density and fracture orientations - in bulk as well as locally. The 3D analyses are complemented with thin sections made to provide some 2D information with a much higher detail than the μCT data. Finally, gas- and water permeability measurements under confining pressure provide an important link (at least in order of magnitude) of the µCT results towards more realistic reservoir conditions. Our results show that 3D μCT can be applied efficiently on plug-sized samples of naturally fractured rocks, and that several important parameters can be extracted. μCT can therefore be a useful addition to studies on such reservoir rocks, and provide valuable input for modelling and simulations. Also permeability experiments under confining pressure provide important additional insights. Combining these and other methods can therefore be a powerful approach in microstructural analysis of reservoir rocks, especially when applying the concepts that we present (on a small set of samples) in a larger study, in an automated and standardised manner.

Scorpions are among the oldest terrestrial arthropods, which are distributed worldwide, except for Antarctica and some Pacific islands. Scorpion envenomation represents a public health problem in several parts of the world. Mexico harbors the highest diversity of scorpions in the world, including some of the world's medically important scorpion species. The systematics and diversity of Mexican scorpion fauna has not been revised in the past decade; and due to recent and exhaustive collection efforts as part of different ongoing major revisionary systematic projects, our understanding of this diversity has changed compared with previous assessments. Given the presence of several medically important scorpion species, the study of their venom in the country is also important. In the present contribution, the diversity of scorpion species in Mexico is revised and updated based on several new systematic contributions; 281 different species are recorded. Commentaries on recent venomic, ecological and behavioral studies of Mexican scorpions are also provided. A list containing the most important peptides identified from 16 different species is included. A graphical representation of the different types of components found in these venoms is also revised. A map with hotspots showing the current knowledge on scorpion distribution and areas explored in Mexico is also provided.

Air pollution is defined as a phenomenon harmful to the ecological system and the normal conditions of human existence and development when some substances in the atmosphere exceed a certain concentration.

Air pollution is defined as a phenomenon harmful to the ecological system and the normal conditions of human existence and development when some substances in the atmosphere exceed a certain concentration. In the face of increasingly serious environmental pollution problems, scholars have conducted a significant quantity of related research, and in those studies, the forecasting of air pollution has been of paramount importance. As a precaution, the air pollution forecast is the basis for taking effective pollution control measures, and accurate forecasting of air pollution has become an important task. Extensive research indicates that the methods of air pollution forecasting can be broadly divided into three classical categories: statistical forecasting methods, artificial intelligence methods, and numerical forecasting methods. More recently, some hybrid models have been proposed, which can improve the forecast accuracy.

2018-06-01

Percentage study weights in meta-analysis reveal the contribution of each study toward the overall summary results and are especially important when some studies are considered outliers or at high risk of bias. In meta-analyses of test accuracy reviews, such as a bivariate meta-analysis of sensitivity and specificity, the percentage study weights are not currently derived. Rather, the focus is on representing the precision of study estimates on receiver operating characteristic plots by scaling the points relative to the study sample size or to their standard error. In this article, we recommend that researchers should also provide the percentage study weights directly, and we propose a method to derive them based on a decomposition of Fisher information matrix. This method also generalises to a bivariate meta-regression so that percentage study weights can also be derived for estimates of study-level modifiers of test accuracy. Application is made to two meta-analyses examining test accuracy: one of ear temperature for diagnosis of fever in children and the other of positron emission tomography for diagnosis of Alzheimer's disease. These highlight that the percentage study weights provide important information that is otherwise hidden if the presentation only focuses on precision based on sample size or standard errors. Software code is provided for Stata, and we suggest that our proposed percentage weights should be routinely added on forest and receiver operating characteristic plots for sensitivity and specificity, to provide transparency of the contribution of each study toward the results. This has implications for the PRISMA-diagnostic test accuracy guidelines that are currently being produced. Copyright © 2017 John Wiley & Sons, Ltd.

A Narrative Review on the Human Health Effects of Ambient Air Pollution in Sub-Saharan Africa: An Urgent Need for Health Effects Studies

An important aspect of the new sustainable development goals (SDGs) is a greater emphasis on reducing the health impacts from ambient air pollution in developing countries. Meanwhile, the burden of human disease attributable to ambient air pollution in sub-Saharan Africa is growing, yet estimates of its impact on the region are possibly underestimated due to a lack of air quality monitoring, a paucity of air pollution epidemiological studies, and important population vulnerabilities in the region. The lack of ambient air pollution epidemiologic data in sub-Saharan Africa is also an important global health disparity. Thousands of air pollution health effects studies have been conducted in Europe and North America, rather than in urban areas that have some of the highest measured air pollution levels in world, including urban areas in sub-Saharan Africa. In this paper, we provide a systematic and narrative review of the literature on ambient air pollution epidemiological studies that have been conducted in the region to date. Our review of the literature focuses on epidemiologic studies that measure air pollutants and relate air pollution measurements with various health outcomes. We highlight the gaps in ambient air pollution epidemiological studies conducted in different sub-regions of sub-Saharan Africa and provide methodological recommendations for future environmental epidemiology studies addressing ambient air pollution in the region.

Autophagy in Drosophila melanogaster.

PubMed

McPhee, Christina K; Baehrecke, Eric H

2009-09-01

Macroautophagy (autophagy) is a bulk cytoplasmic degradation process that is conserved from yeast to mammals. Autophagy is an important cellular response to starvation and stress, and plays critical roles in development, cell death, aging, immunity, and cancer. The fruit fly Drosophila melanogaster provides an excellent model system to study autophagy in vivo, in the context of a developing organism. Autophagy (atg) genes and their regulators are conserved in Drosophila, and autophagy is induced in response to nutrient starvation and hormones during development. In this review we provide an overview of how Drosophila research has contributed to our understanding of the role and regulation of autophagy in cell survival, growth, nutrient utilization, and cell death. Recent Drosophila research has also provided important mechanistic information about the role of autophagy in protein aggregation disorders, neurodegeneration, aging, and innate immunity. Differences in the role of autophagy in specific contexts and/or cell types suggest that there may be cell-context-specific regulators of autophagy, and studies in Drosophila are well-suited to yield discoveries about this specificity.

Two-fluid dusty shocks: simple benchmarking problems and applications to protoplanetary discs

NASA Astrophysics Data System (ADS)

Lehmann, Andrew; Wardle, Mark

2018-05-01

The key role that dust plays in the interstellar medium has motivated the development of numerical codes designed to study the coupled evolution of dust and gas in systems such as turbulent molecular clouds and protoplanetary discs. Drift between dust and gas has proven to be important as well as numerically challenging. We provide simple benchmarking problems for dusty gas codes by numerically solving the two-fluid dust-gas equations for steady, plane-parallel shock waves. The two distinct shock solutions to these equations allow a numerical code to test different forms of drag between the two fluids, the strength of that drag and the dust to gas ratio. We also provide an astrophysical application of J-type dust-gas shocks to studying the structure of accretion shocks on to protoplanetary discs. We find that two-fluid effects are most important for grains larger than 1 μm, and that the peak dust temperature within an accretion shock provides a signature of the dust-to-gas ratio of the infalling material.

Interpersonal relations between health care providers and young clients have long being cited as an important element for improving client up take of services, satisfaction and overall health outcomes. In an era of HIV and AIDS this forms a critical determinant to young people accessing sexual and reproductive health care. This study explores to what extent interpersonal relations form a barrier to young peoples access to and satisfaction of health services. The study draws on data from 200 client exit interviews and four in-depth interviews conducted with university students and university health care staff in Kwazulu-Natal, South Africa. While young people are aware of the importance of utilising STI, HIV and family planning services they experienced barriers in their relationship with providers. This served as a deterrent to their use of the health facility. Adequate training in interpersonal relations for youth-friendly service provision is essential in helping overcome communication problems and enabling providers to interact with young clients at a more personal level.

Attribute importance segmentation of Norwegian seafood consumers: The inclusion of salient packaging attributes.

2017-10-01

The main purpose of this study is to identify consumer segments based on the importance of product attributes when buying seafood for homemade meals on weekdays. There is a particular focus on the relative importance of the packaging attributes of fresh seafood. The results are based on a representative survey of 840 Norwegian consumers between 18 and 80 years of age. This study found that taste, freshness, nutritional value and naturalness are the most important attributes for the home consumption of seafood. Except for the high importance of information about expiration date, most other packaging attributes have only medium importance. Three consumer segments are identified based on the importance of 33 attributes associated with seafood: Perfectionists, Quality Conscious and Careless Consumers. The Quality Conscious consumers feel more self-confident in their evaluation of quality, and are less concerned with packaging, branding, convenience and emotional benefits compared to the Perfectionists. Careless Consumers are important as regular consumers of convenient and pre-packed seafood products and value recipe information on the packaging. The seafood industry may use the results provided in this study to strengthen their positioning of seafood across three different consumer segments. Copyright © 2017 Elsevier Ltd.

Multimodal fusion of brain imaging data: A key to finding the missing link(s) in complex mental illness

Calhoun, Vince D; Sui, Jing

2016-01-01

It is becoming increasingly clear that combining multi-modal brain imaging data is able to provide more information for individual subjects by exploiting the rich multimodal information that exists. However, the number of studies that do true multimodal fusion (i.e. capitalizing on joint information among modalities) is still remarkably small given the known benefits. In part, this is because multi-modal studies require broader expertise in collecting, analyzing, and interpreting the results than do unimodal studies. In this paper, we start by introducing the basic reasons why multimodal data fusion is important and what it can do, and importantly how it can help us avoid wrong conclusions and help compensate for imperfect brain imaging studies. We also discuss the challenges that need to be confronted for such approaches to be more widely applied by the community. We then provide a review of the diverse studies that have used multimodal data fusion (primarily focused on psychosis) as well as provide an introduction to some of the existing analytic approaches. Finally, we discuss some up-and-coming approaches to multi-modal fusion including deep learning and multimodal classification which show considerable promise. Our conclusion is that multimodal data fusion is rapidly growing, but it is still underutilized. The complexity of the human brain coupled with the incomplete measurement provided by existing imaging technology makes multimodal fusion essential in order to mitigate against misdirection and hopefully provide a key to finding the missing link(s) in complex mental illness.

Campos, Domingos Fernandes; Negromonte Filho, Rinaldo Bezerra; Castro, Felipe Nalon

2017-10-09

Purpose The purpose of this paper is to investigate the expectations and quality gaps in services provided at city public health clinics in the city of Natal, Brazil, from the perspective of patients and healthcare service providers. Design/methodology/approach The research sample consisted of 1,200 patients who used public health services and 265 providers - doctors, nutritionists, physiotherapists, psychologists, pharmacists and managers at three health clinics in the city of Natal, Brazil. A scale with 25 health service attributes was used in data collection. Summary statistics and t-test were used to analyze the data. Findings The results show that the providers think that users have lower levels of expectations than those indicated by the users in all attributes. Providers and users have the most approximate insights into what attributes are considered most important: explanations, level of knowledge and attention dispensed by health professionals. Users and providers perceived similar quality gaps for most of the attributes. The gaps were statistically the same, when comparing the mean quality shortcomings by means of a Student's test, considering a significance level of 5 percent, obtained independently by the manifestation of users and providers. Research limitations/implications The results reveal only a photograph of the moment. The study did not consider the differences that may exist between groups with different income levels, genders or age groups. A qualitative study could improve the understanding of the differences and coincidences of the diverse points of views. A more advanced research could even study possibilities so that health managers could promote changes in the service, some of them low cost, as the health professionals training for contact with patients. Practical implications The evaluation of the service quality complemented by the matrix of opportunities, importance × quality gaps generates information to help make decisions in the rational allocation of available resources and improvement of the quality of the service delivered to patients. Besides, it offers a focus to prioritize specific actions. Originality/value It is important to compare the perceptions of service quality between patients and the healthcare service providers who work in direct contact with them. The managers can smooth out these differences and ensure, over time, customer satisfaction. In this study, providers were asked to express what they think about the expectations of patients and about their own service performance delivered. Thus, not only the traditional gap 5 was measured, but it was also possible to evaluate the distance between what providers think that patients need and their actual needs.

Sesame (Sesamum indicum L.) is an ancient and important oilseed crop grown widely in tropical and subtropical areas. It belongs to the gigantic order Lamiales, which includes many well-known or economically important species, such as olive (Olea europaea), leonurus (Leonurus japonicus) and lavender (Lavandula spica), many of which have important pharmacological properties. Despite their importance, genetic and genomic analyses on these species have been insufficient due to a lack of reference genome information. The now available S. indicum genome will provide an unprecedented opportunity for studying both S. indicum genetic traits and comparative genomics. To deliver S. indicum genomic information to the worldwide research community, we designed Sinbase, a web-based database with comprehensive sesame genomic, genetic and comparative genomic information. Sinbase includes sequences of assembled sesame pseudomolecular chromosomes, protein-coding genes (27,148), transposable elements (372,167) and non-coding RNAs (1,748). In particular, Sinbase provides unique and valuable information on colinear regions with various plant genomes, including Arabidopsis thaliana, Glycine max, Vitis vinifera and Solanum lycopersicum. Sinbase also provides a useful search function and data mining tools, including a keyword search and local BLAST service. Sinbase will be updated regularly with new features, improvements to genome annotation and new genomic sequences, and is freely accessible at http://ocri-genomics.org/Sinbase/. © The Author 2014.

Sellevold, Gerd Sylvi; Egede-Nissen, Veslemøy; Jakobsen, Rita; Sørlie, Venke

2017-01-01

Many nursing homes appear as multicultural workplaces where the majority of healthcare providers have an ethnic minority background. This environment creates challenges linked to communication, interaction and cultural differences. Furthermore, the healthcare providers have varied experiences and understanding of what quality care of patients with dementia involves. The aim of this study is to illuminate multi-ethnic healthcare providers' lived experiences of their own working relationship, and its importance to quality care for people with dementia. The study is part of a greater participatory action research project: 'Hospice values in the care for persons with dementia'. The data material consists of extensive notes from seminars, project meetings and dialogue-based teaching. The text material was subjected to phenomenological-hermeneutical interpretation. Participants and research context: Participants in the project were healthcare providers working in a nursing home unit. The participants came from 15 different countries, had different formal qualifications, varied backgrounds and ethnic origins. Ethical considerations: The study is approved by the Norwegian Regional Ethics Committee and the Norwegian Social Science Data Services. The results show that good working relationships, characterized by understanding each other's vulnerability and willingness to learn from each other through shared experiences, are prerequisites for quality care. The healthcare providers further described ethical challenges as uncertainty and different understandings. The results are discussed in the light of Lögstrup's relational philosophy of ethics and the concepts of vulnerability, ethic responsibility, trust and openness of speech. The prerequisite for quality care for persons with dementia in a multicultural working environment is to create arenas for open discussions between the healthcare providers. Leadership is of great importance.

Are Integrated Plan Providers Associated With Lower Premiums on the Health Insurance Marketplaces?

La Forgia, Ambar; Maeda, Jared Lane K; Banthin, Jessica S

2018-04-01

As the health insurance industry becomes more consolidated, hospitals and health systems have started to enter the insurance business. Insurers are also rapidly acquiring providers. Although these "vertically" integrated plan providers are small players in the insurance market, they are becoming more numerous. The health insurance marketplaces (HIMs) offer a unique setting to study integrated plan providers relative to other insurer types because the HIMs were designed to promote competition. In this descriptive study, the authors compared the premiums of the lowest priced silver plans of integrated plan providers with other insurer types on the 2015 and 2016 HIMs. Integrated plan providers were associated with modestly lower premiums relative to most other insurer types. This study provides early insights into premium competition on the HIMs. Examining integrated plan providers as a separate insurer type has important policy implications because they are a growing segment of the marketplaces and their pricing behavior may influence future premium trends.

Perceptions of importance, preparedness and classroom implementation of the National Science Education Standards as perceived by Texas science education leaders

NASA Astrophysics Data System (ADS)

Dutcher, Joyce Marie

At a time when the nation is challenged by a competitive world economy, learning organizations are experiencing the dynamics of change. Recent mandates, like the No Child Left Behind Act (2001) and the Texas' 1999 education reform law initiating the Texas Assessment of Knowledge and Skills put an impetus on educators to implement standards reform practices that would lead to improved teaching and learning. Texas science education leaders have the challenging task of leading National Science Education Standards (NSES) reform in Texas schools/districts. Therefore, it is important that they are informed about the NSES and are prepared to provide leadership support for their implementation. How they perceive themselves in this role could possibly affect the support they give to teachers and others, ultimately affecting how the NSES are implemented in classrooms. This correlational and descriptive research study used archival data collected at a time the NSES were first being implemented to (a) determine the degree of relations that exist between the leaders' perceived importance of effective practices and their perceived preparedness to provide leadership support for their implementation, and (b) examine influences that may exist between the leaders' perceived importance/preparedness and their perceived frequency of occurrence of related teacher and student activities. The data set used was gathered from a preliminary study of the researcher (Dutcher, 2000). It involved responses from 90 Texas science education leaders who voluntarily responded to the, "Leader Survey Questionnaire: Principles of the National Science Education Standards". Results showed support for the idea that leaders' perceptions of importance for effective practices were significant predictors of their own perceived preparedness to provide leadership support for the same. However in contrast, the results did not show consistent support for the idea that the leaders' perceived importance or preparedness to provide leadership support for the effective practices influenced their perceived frequency of occurrence of related teacher or student activities. These findings will contribute to existing literature and may help educators identify gaps that exist in the science education reform process. These results may be used to design and plan professional development programs for leaders and their teachers.

The absent discourse of communication: understanding ethics of provider-patient relationship in six hospitals in urban India

2013-01-01

Understanding the complexities of a provider-patient relationship is considered to be of critical importance especially in medical ethics. It is important to understand this relation from the perspectives of all stakeholders. This article derives from a qualitative study conducted across six obstetric care providing institutions in the cities of Mumbai and Navi Mumbai, India, over a period of 10 months. Thirty obstetricians were interviewed in-depth to understand what they perceived as the most important aspect in developing a good provider-patient relationship. The study found that while most providers highlighted the point of communication as the most critical part of the provider-patient relationship, they admitted that they could not engage in communication with the patients for various reasons. Obstetric consultants and residents said that they were too overburdened to spend time communicating with patients; providers working in public hospitals added that the lack of education of their patients posed a hindrance in effective communication. However, providers practicing in private institutions explained that they faced a challenge in communicating with patients because their patients came from educated families who tended to trust the provider less and were generally more critical of the provider’s clinical judgement. The article shows how provider-patient communication exists as an idea among medical providers but is absent in daily clinical practice. This gives rise to a discourse shaped around an absence. The authors conclude by decoding the term ‘communication’ – they read the word against the context of its use in the interviews, and argue that for the providers ‘communication’ was not intended to be a trope towards setting up a dialogue-based, egalitarian provider-patient relationship. Providers used the word in lieu of ‘counselling’, ‘guiding’, ‘talking to’. It concludes that, despite the providers’ insisting on the significance of communication and complaining about its absence, what they desired in reality was not the possibility of a dialogue with the patient or a chance to be able to share decision-making power with the patient, but to be able to provide better instructions and chart out what was best for them in a more detailed way.

2017-06-01

As the population of older adults increase so will the need for care providers, both human and robot. Trust is a key aspect to establish and maintain a successful older adult-care provider relationship. However, due to trust volatility it is essential to understand it within specific contexts. This proposed mixed methods study will explore what dimensions of trust emerge as important within the human-human and human-robot dyads in older adults and care providers. First, this study will help identify key qualities that support trust in a care provider relationship. By understanding what older adults perceive as needing to trust humans and robots for various care tasks, we can begin to provide recommendations based on user expectations for design to support trust.

Fundholders' referral patterns and perceptions of service quality in hospital provision of elective general surgery.

Whynes, D K; Reed, G

1994-01-01

BACKGROUND. The introduction of fundholding established an internal market in public sector health care, involving purchasers and providers contracting for the supply of health care. AIM. This study set out to examine fundholders' hospital referral patterns, and to evaluate the quality of the service provided to patients undergoing elective general surgery, as perceived by fundholding general practitioners. METHOD. A questionnaire was posted to the senior partners of all fundholding practices in the Trent Regional Health Authority area. This questionnaire requested assessments of the importance of 13 specified aspects of service quality and the quality of provision by general practitioners' most frequently-used hospitals. Five-point scales were employed in each case. Respondents were asked to provide additional details about their practice. RESULTS. A 67% response rate was achieved. Confidence in the consultant's ability, short waiting times and informative feedback from the providers emerged as the most important elements in referral decisions, while the cost of treatment and patient convenience received lower importance ratings. In terms of how well their providers were seen to perform, fundholders ranked confidence in the consultant and patient convenience highest, and style of hospital management lowest. The majority of referrals seemed to be local. CONCLUSION. Judged in terms of fundholders' perceptions, sizeable variations in service quality between hospital providers of general surgery are evident. PMID:7748666

Catheter-based high-frequency intraluminal ultrasound imaging is a powerful tool to study esophageal dysmotility patients.

High-resolution manometry (HRM) is currently the most important diagnostic test for esophageal motility disorders, providing information on the contraction pattern of the circular muscle layer, which helps classify these esophageal motor diseases. However, with the increasing development of ultrasound, other techniques, such as high-frequency intraluminal ultrasound (HFIUS), have gained importance. This technique uses a flexible shaft with a central wire integrated into a standard endoscope, which facilitates real-time sonography. Its main utility is to provide anatomical information on the structure of the esophageal wall, including both the circular and longitudinal layers that constitute the esophageal muscularis propria. Increasing knowledge about these motility disorders has led to the hypothesis that, in addition to an abnormal contraction pattern of the circular muscle, an overall increased muscle thickness and an abnormal longitudinal muscle contraction could be added as pathophysiological factors. The increase in muscle thickness could be an important indicator of the severity of diseases, such as achalasia, distal esophageal spasm, or hypercontractile esophagus. More studies are required before definitive conclusions can be reached, but HFIUS employed simultaneously with HRM could provide a more complete and precise evaluation of these esophageal motor disorders. © 2017 New York Academy of Sciences.

The Icelandic old-age care system is universal and the official goal is to support older people live independently for as long as possible. The aim of this study is to analyse living conditions and use of formal and informal care of older people in Iceland. The results are based on the new study ICEOLD, a telephone survey which included questions on social network, health, activities of daily living, and received support from the community and/or from relatives, neighbours, and friends. Almost half of the sample (47%) receives some kind of care, with 27% of them receiving only informal care, which is understood to mean that informal care is of great importance and families are the main providers of help. For hypothetical future long-term care, older people wish to be cared for in their homes, but those already in need of assistance prefer to be cared for in institutions. Caring relatives are the main providers of support to older people in their homes and it is important to provide them with suitable formal support when the care responsibility increases. As the care system in Iceland is now under reconstruction, the important contribution of informal carers must be recognised and taken into account when planning the care of older people.

The program of research outlined should advance significantly the understanding of the spectral signal of montmorillonites in general and the variations produced in it by structural and surface ferric and ferrous iron and interlayer water as a function of several environmental conditions that are different between Earth and Mars. In addition, an extensive data base was collected providing spectral characterization of several features (iron, both surface and structural, OH-groups, both structural and from adsorbed water and O(-) centers) that are known, or thought to be, influential in directing the surface activity of these important materials. With this data base with which to assess the results of the Viking labeled release simulation studies, it should be possible to gain important insights into the mechanisms of surface reactivity for this important chemical reaction. The results to be gained from these studies will provide a significant body of ground base truth from which to assess: the presence of smectite clays on Mars; the mineralogical form in which the Martian iron is bound; establish upper limits on the present surface water content of Martian soils; perhaps provide insights on the Martian surface radiation history; and to make strong predictions about the nature of surface chemistry on Mars, if iron-bearing clays are a significant component of the surface mineralogical assemblage.

Anti-aging medicine--the good, the bad, and the ugly.

Gammack, Julie K; Morley, John E

2004-05-01

Complementary and alternative medicine has flourished since the beginning of time because of a human need to postpone the aging process and to reverse disease. Complementary and alternative medicine sells, because in some cases it works as well or better than mainstream medicine. In addition, many practitioners of complementary medicine understand Hippocrates' aphorism: "It is more important to know the person that has the disease than the disease the person has." It is important to recognize that spending time with the patient is often as therapeutic as drugs. CAM offers patients the time, touch, attention, and level of personal interaction that are increasingly uncommon in contemporary medical care. There is a major need for large and appropriately designed studies to test the effectiveness of complementary techniques. As in other areas of health care, studies in the elderly are consistently lacking. With the growing interest in CAM, it is important for medical providers to keep an open mind--to both the potential benefits and potential harms of alternative treatments. When treatments are shown to be dangerous or ineffective, we must educate the public and work to remove these therapies from the market place. When treatments are proven effective, Western and Eastern medical providers must work together with patients to provide the most appropriate and comprehensive health care.

Nutraceuticals in cardiovascular prevention: lessons from studies on endothelial function.

2010-08-01

An "unhealthy" diet is considered as a main cause of increased atherosclerotic cardiovascular disease in the industrialized countries. There is a substantial interest in the potential cardiovascular protective effects of "nutraceuticals," that is food-derived substances that exert beneficial health effects. The correct understanding of cardiovascular effects of these compounds will have important implications for cardiovascular prevention strategies. Endothelial dysfunction is thought to play an important role in development and progression of atherosclerosis, and the characterization of the endothelial effects of several nutraceuticals may provide important insights into their potential role in cardiovascular prevention. At the same time, the analysis of the endothelial effects of nutraceuticals may also provide valuable insights into mechanisms of why certain nutraceuticals may not be effective in cardiovascular prevention, and it may aid in the identification of food-derived substances that may have detrimental cardiovascular effects. These findings further support the notion that nutraceuticals do need support from large clinical outcome trials with respect to their efficacy and safety profile for cardiovascular prevention, before their widespread use can be recommended. In fact, the term nutraceutical was coined to encourage an extensive and profound research activity in this field, and numerous large-scale clinical outcome trials to examine the effects of nutraceuticals on cardiovascular events have now been performed or are still ongoing. Whereas it is possible that single nutraceuticals may be effective in cardiovascular prevention, this field of research provides also valuable insights into which food components may be particularly important for cardiovascular prevention, to further advice the composition of a particularly healthy diet. The present review summarizes recent studies on the endothelial effects of several nutraceuticals, that have been intensely studied.

Public mental health services in the community are broad and continue to expand to address the multiple issues faced by those with serious mental illnesses. However, few studies examine and contrast how helpful consumers and providers find the spectrum of services. The present study examines the services at community mental health service clinics (CMHCs) from the perspectives of providers and consumers. There were 351 consumers and 147 providers from 15 CMHCs who rated and ranked the helpfulness of 24 types of common services. All of the agencies were participating in a Practice-Based Research Network (PBRN). Social support was the highest rated service by both types of respondents, and the creation of a welcoming environment was the highest ranked service by both. There were also areas of disagreement. Consumers identified traditional mental health services (individual therapy and medication services) as being most helpful to them whereas providers selected longer-term services that promote self-reliance (e.g., securing housing, and promoting self-sufficiency) as the most helpful. Understanding how consumers and providers perceive the range of CMHC services provided in usual care is important to develop new targets for intervention. A welcoming milieu and providing social support appear important to both, but significant differences exist between these groups regarding other aspects of services. This holds implications for the design and implementation of consumer-driven services. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

2014-01-01

Quantile regression provides a more thorough view of the effect of covariates on a response. Nonparametric quantile regression has become a viable alternative to avoid restrictive parametric assumption. The problem of variable selection for quantile regression is challenging, since important variables can influence various quantiles in different ways. We tackle the problem via regularization in the context of smoothing spline ANOVA models. The proposed sparse nonparametric quantile regression (SNQR) can identify important variables and provide flexible estimates for quantiles. Our numerical study suggests the promising performance of the new procedure in variable selection and function estimation. Supplementary materials for this article are available online.

Issues related to program context are important components of population health interventions and particularly among complex, adaptive initiatives in schools. Health Promoting Schools (HPS) is a global approach to support early development of healthy behaviors among children and youth. The purpose of this study was to explicate the practical and contextual processes that influenced implementation of HPS in schools in Nova Scotia (Canada). Using a case-study approach, data was collected using interviews (n=14) with principals, teachers and parents, observations collected during school visits and document review in five diverse schools. Case study schools reported a variety of HPS practices and three key themes emerged that provided context to the processes that facilitated their implementation. The results suggest that although school characteristics (theme 1), like staff allocation, physical location and resources, are important, these barriers can be mitigated by building organizational capacity (theme 2) and establishing a supportive school community culture (theme 3). The study provided insight to the variability in implementation by describing how contextual barriers were experienced and mitigated by schools. Establishing a broad system to support HPS, with collaboration across health and education sectors, could help to progress adoption, implementation and sustainability of HPS.

Kurz, Richard S; Yager, Christopher; Yager, James D; Foster, Allison; Breidenbach, Daniel H; Irwin, Zachary

In 2014, the National Board of Public Health Examiners performed a job task analysis (JTA) to revise the Certified in Public Health (CPH) examination. The objectives of this study were to describe the development, administration, and results of the JTA survey; to present an analysis of the survey results; and to review the implications of this first-ever public health JTA. An advisory committee of public health professionals developed a list of 200 public health job tasks categorized into 10 work domains. The list of tasks was incorporated into a web-based survey, and a snowball sample of public health professionals provided 4850 usable responses. Respondents rated job tasks as essential (4), very important (3), important (2), not very important (1), and never performed (0). The mean task importance ratings ranged from 2.61 to 3.01 (important to very important). The highest mean ratings were for tasks in the ethics domain (mean rating, 3.01). Respondents ranked 10 of the 200 tasks as the most important, with mean task rankings ranging from 2.98 to 3.39. We found subtle differences between male and female respondents and between master of public health and doctor of public health respondents in their rankings. The JTA established a set of job tasks in 10 public health work domains, and the results provided a foundation for refining the CPH examination. Additional steps are needed to further modify the content outline of the examination. An empirical assessment of public health job tasks, using methods such as principal components analysis, may provide additional insight.

The convenience of accessing antiretroviral therapy (ART) is important for initial access to care and subsequent adherence to ART. We conducted a qualitative study of people living with HIV/AIDS (PLWHA) and ART healthcare providers in Ghana in 2005. The objective of this study was to explore the participants' perceived convenience of accessing ART by PLWHA in Ghana. The convenience of accessing ART was evaluated from the reported travel and waiting times to receive care, the availability, or otherwise, of special considerations, with respect to the waiting time to receive care, for those PLWHA who were in active employment in the formal sector, the frequency of clinic visits before and after initiating ART, and whether the PLWHA saw the same or different providers at each clinic visit (continuity of care). This qualitative study used in-depth interviews based on Yin's case-study research design to collect data from 20 PLWHA and 24 ART healthcare providers as study participants. • Reported travel time to receive ART services ranged from 2 to 12 h for 30% of the PLWHA. • Waiting time to receive care was from 4 to 9 h. • While known government workers, such as teachers, were attended to earlier in some of the centres, this was not a consistent practice in all the four ART centres studied. • The PLWHA corroborated the providers' description of the procedure for initiating and monitoring ART in Ghana. • PLWHA did not see the same provider every time, but they were assured that this did not compromise the continuity of their care. Our study suggests that convenience of accessing ART is important to both PLWHA and ART healthcare providers, but the participants alluded to other factors, including open provider-patient communication, which might explain the PLWHA's understanding of the constraints under which they were receiving care. The current nation-wide coverage of the ART programme in Ghana, however, calls for the replication of this study to identify possible perception changes over time that may need attention. Our study findings can inform interventions to promote access to ART, especially in Africa.

The present research examined cultural differences in the type and frequency of support provided as well as the motivations underlying these behaviors. Study 1, an open-ended survey, asked participants about their social interactions in the past 24 hours and found that European Americans reported providing emotion-focused support more frequently than problem-focused support, whereas Japanese exhibited the opposite pattern. Study 2, a closed-ended questionnaire study, found that, in response to the close other's big stressor, European Americans provided more emotion-focused support whereas Japanese provided equivalent amounts of emotion-focused and problem-focused support. In addition, Study 2 examined motivational explanations for these differences. Social support provision was motivated by the goal of closeness and increasing recipient self-esteem among European Americans, but only associated with the motive for closeness among Japanese. These studies illustrate the importance of considering cultural context and its role in determining the meaning and function of various support behaviors.

Adult obesity in the UK remains a public health priority. Current guidance recommends local areas provide multicomponent interventions to treat adults with overweight and obesity; however, there is currently a dearth of published evidence on the evaluation of these programmes. This study reports on a mixed method evaluation of seven tier 2 weight management programmes funded by a local authority in the North of England through their public health grant (a lifestyle multicomponent weight management programme for the treatment of adults with overweight and obesity, but not severe obesity, or obesity with severe co-morbidities). Data collected from over 2000 participants demonstrated that the proportion of participants achieving 5% initial body weight loss was comparable to that reported in recent UK weight management trials. Two services exceeded national criteria of 30% of participants achieving 5% initial body weight loss at 12 weeks, although long term data was limited. Greater weight loss was also observed in participants aged 35-44 and those without co-morbidities. This study provides important learning points for improvements in real world weight management services, these include: standardised data collection and management tools; staff training and communication requirements; the importance of programmes that are joined up to wider support services; and the importance of providing ongoing peer and provider support, continuous monitoring and feedback, and physical activities tailored to user needs. © 2018 World Obesity Federation.

Nonindependence and sensitivity analyses in ecological and evolutionary meta-analyses.

2017-05-01

Meta-analysis is an important tool for synthesizing research on a variety of topics in ecology and evolution, including molecular ecology, but can be susceptible to nonindependence. Nonindependence can affect two major interrelated components of a meta-analysis: (i) the calculation of effect size statistics and (ii) the estimation of overall meta-analytic estimates and their uncertainty. While some solutions to nonindependence exist at the statistical analysis stages, there is little advice on what to do when complex analyses are not possible, or when studies with nonindependent experimental designs exist in the data. Here we argue that exploring the effects of procedural decisions in a meta-analysis (e.g. inclusion of different quality data, choice of effect size) and statistical assumptions (e.g. assuming no phylogenetic covariance) using sensitivity analyses are extremely important in assessing the impact of nonindependence. Sensitivity analyses can provide greater confidence in results and highlight important limitations of empirical work (e.g. impact of study design on overall effects). Despite their importance, sensitivity analyses are seldom applied to problems of nonindependence. To encourage better practice for dealing with nonindependence in meta-analytic studies, we present accessible examples demonstrating the impact that ignoring nonindependence can have on meta-analytic estimates. We also provide pragmatic solutions for dealing with nonindependent study designs, and for analysing dependent effect sizes. Additionally, we offer reporting guidelines that will facilitate disclosure of the sources of nonindependence in meta-analyses, leading to greater transparency and more robust conclusions. © 2017 John Wiley & Sons Ltd.

Challenges and opportunities for tissue-engineering polarized epithelium.

2014-02-01

The epithelium is one of the most important tissue types in the body and the specific organization of the epithelial cells in these tissues is important for achieving appropriate function. Since many tissues contain an epithelial component, engineering functional epithelium and understanding the factors that control epithelial maturation and organization are important for generating whole artificial organ replacements. Furthermore, disruption of the cellular organization leads to tissue malfunction and disease; therefore, engineered epithelium could provide a valuable in vitro model to study disease phenotypes. Despite the importance of epithelial tissues, a surprisingly limited amount of effort has been focused on organizing epithelial cells into artificial polarized epithelium with an appropriate structure that resembles that seen in vivo. In this review, we provide an overview of epithelial tissue organization and highlight the importance of cell polarization to achieve appropriate epithelium function. We next describe the in vitro models that exist to create polarized epithelium and summarize attempts to engineer artificial epithelium for clinical use. Finally, we highlight the opportunities that exist to translate strategies from tissue engineering other tissues to generate polarized epithelium with a functional structure.

Applications of species distribution modeling to paleobiology

2011-10-01

Species distribution modeling (SDM: statistical and/or mechanistic approaches to the assessment of range determinants and prediction of species occurrence) offers new possibilities for estimating and studying past organism distributions. SDM complements fossil and genetic evidence by providing (i) quantitative and potentially high-resolution predictions of the past organism distributions, (ii) statistically formulated, testable ecological hypotheses regarding past distributions and communities, and (iii) statistical assessment of range determinants. In this article, we provide an overview of applications of SDM to paleobiology, outlining the methodology, reviewing SDM-based studies to paleobiology or at the interface of paleo- and neobiology, discussing assumptions and uncertainties as well as how to handle them, and providing a synthesis and outlook. Key methodological issues for SDM applications to paleobiology include predictor variables (types and properties; special emphasis is given to paleoclimate), model validation (particularly important given the emphasis on cross-temporal predictions in paleobiological applications), and the integration of SDM and genetics approaches. Over the last few years the number of studies using SDM to address paleobiology-related questions has increased considerably. While some of these studies only use SDM (23%), most combine them with genetically inferred patterns (49%), paleoecological records (22%), or both (6%). A large number of SDM-based studies have addressed the role of Pleistocene glacial refugia in biogeography and evolution, especially in Europe, but also in many other regions. SDM-based approaches are also beginning to contribute to a suite of other research questions, such as historical constraints on current distributions and diversity patterns, the end-Pleistocene megafaunal extinctions, past community assembly, human paleobiogeography, Holocene paleoecology, and even deep-time biogeography (notably, providing insights into biogeographic dynamics >400 million years ago). We discuss important assumptions and uncertainties that affect the SDM approach to paleobiology - the equilibrium postulate, niche stability, changing atmospheric CO 2 concentrations - as well as ways to address these (ensemble, functional SDM, and non-SDM ecoinformatics approaches). We conclude that the SDM approach offers important opportunities for advances in paleobiology by providing a quantitative ecological perspective, and hereby also offers the potential for an enhanced contribution of paleobiology to ecology and conservation biology, e.g., for estimating climate change impacts and for informing ecological restoration.

Bactrocera flies are the serious pests of fruit, vegetables, and nuts over the world. Bactrocera tau Walker is an economically important pest of agricultural crops. In Asia, approximately 30-40% losses of agricultural products are caused by B. tau infestation every year. In Asia, the B. tau contains a complex of sibling species that called the tau complex. However, the basic studies of B. tau and complex species are very important for integrated management. A comprehensive review of the B. tau and complex species has not been provided elsewhere. So, considering the importance of B. tau and complex species, this study provides the published information on ecology, nomenclature, identification tools, geographical distribution, potential invasion, and IPM tactics of B. tau and complex species, which would be more informative for publication facilitating related to integrated pest management (IPM) strategies of B. tau and complex species. In IPM of B. tau and complex species, the phytochemical and biological controls have not been applied successfully in Asia; there is an urgent need to study and applications of these two mentioned control techniques against the B. tau and complex species in Asia.

2017-07-01

Daily interprofessional rounds enhance collaboration among healthcare providers and improve hospital performance measures. However, it is unclear how healthcare providers' goals influence the processes and outcomes of interprofessional rounds. The purpose of this case study was to explore the goals of healthcare providers attending interprofessional rounds in an internal medicine ward. The second purpose was to explore the challenges encountered by healthcare providers while pursuing these goals. Three focus groups were held with healthcare providers of diverse professional backgrounds. Focus group field notes and transcripts were analysed using thematic analysis. The data indicated that there was no consensus among healthcare providers regarding the goals of interprofessional rounds. Discharge planning and patient care delivery were perceived as competing priorities during rounds, which limited the participation of healthcare providers. Nevertheless, study participants identified goals of rounds that were relevant to most care providers: developing shared perspectives of patients through direct communication, promoting collaborative decision making, coordinating care, and strengthening interprofessional relationships. Challenges in achieving the goals of interprofessional rounds included inconsistent attendance, exchange of irrelevant information, variable participation by healthcare providers, and inconsistent leadership. The findings of this study underscore the importance of shared goals in the context of interprofessional rounding.

Lesbian, gay, bisexual, transgender and questioning (LGBTQ) youth appear to be at higher risk for certain adverse health outcomes, and to have several personal, cultural and structural barriers to accessing healthcare. Little is known, however, about the experiences of LGBTQ youth with healthcare providers and healthcare services. Our goal was to recruit a sample of LGBTQ youth and to determine their preferences regarding healthcare providers, healthcare settings and the health issues that they consider important to discuss with a healthcare provider. We conducted a cross-sectional Internet-based survey. Respondents ages 13-21 years and living in the U.S. or Canada were asked to review three lists of items pertaining to qualities of healthcare providers, qualities of offices or health centers, and concerns or problems to discuss with a healthcare provider, and then to assign for each item a relative importance. Items in each of the three lists were then ranked, and differences among ranks were assessed. Inter-group differences by age, gender, and race/ethnicity were also assessed. 733 youth met eligibility criteria. Youth indicated as most important competence overall and specifically in issues unique to taking care of youth and LGBTQ persons, as well as being respected and treated by providers the same as other youth. Notably, youth ranked as least important the provider's gender and sexual orientation. Youth ranked accessibility issues higher than specific services provided. As health concerns to discuss with a provider, youth ranked preventive healthcare, nutrition, safe sex, and family as important as common morbidities. Youth placed as much importance on provider qualities and interpersonal skills as provider knowledge and experience, and placed little importance on a provider's gender and sexual orientation. Youth indicated the importance of providers addressing not only health risks, but also wellness and health promotion, and to do so within the context of home and family. Subgroup analyses underscore the need for greater sensitivity to both cultural and developmental differences among LGBTQ youth. These results provide a foundation for further research about healthcare services and delivery systems for youth, training initiatives for healthcare providers, and the role of utilizing the Internet for health research purposes to access and recruit hard-to-reach youth.

We highlight different methods used to manipulate the importance of a prospective memory task such as providing rewards, importance relative to other ongoing activities, absolute importance, and providing social motives. Moreover, we address the relationship between importance and other factors known to affect prospective memory and ongoing task performance such as type of prospective memory task (time-, event-, or activity-based), cognitive loads, and processing overlaps. Finally, we provide a connection to motivation, we summarize the effects of task importance and we identify important venues for future research. PMID:25018743

The motivation to identify the causes of rising health care cost and variations across providers has intensified in all industrialized countries. These countries have an ongoing debate on efficiency and effectiveness in hospital production. In this debate, national and international comparative studies are important. There are very few international comparative studies that include Norwegian hospitals. Actually we know very little about how Norwegian hospitals are performing compared to others. This paper gives an introduction to comparative studies and to the DEA model which is often used in such studies and also a multilevel model which is not so common. A short review is given of a comparative study of Norwegian and North American hospitals. I also discuss the feasibility of comparative studies of hospitals from the Nordic countries, with references to several comparative studies performed in these countries. Comparative studies are often closely linked to national health politics, policy making and reforms; thus the outcome of such studies is important for the hospitals included. This makes such studies a sensitive field of research. It is important to be aware of the strength and weaknesses of comparative studies and acknowledge their importance beyond the development of new knowledge.

Latinos living with HIV residing in the US-Mexico border region frequently seek care on both sides of the border. Given this fact, a border health perspective to understanding barriers to care is imperative to improve patient health outcomes. This qualitative study describes and compares experiences and perceptions of Mexican and US HIV care providers regarding barriers to HIV care access for Latino patients living in the US-Mexico border region. In 2010, we conducted in-depth qualitative interviews with HIV care providers in Tijuana (n = 10) and San Diego (n = 9). We identified important similarities and differences between Mexican and US healthcare provider perspectives on HIV care access and barriers to service utilisation. Similarities included the fact that HIV-positive Latino patients struggle with access to ART medication, mental health illness, substance abuse and HIV-related stigma. Differences included Mexican provider perceptions of medication shortages and US providers feeling that insurance gaps influenced medication access. Differences and similarities have important implications for cross-border efforts to coordinate health services for patients who seek care in both countries.

Nuclear import of HIV-1 intracellular reverse transcription complexes is mediated by importin 7

PubMed Central

Fassati, Ariberto; Görlich, Dirk; Harrison, Ian; Zaytseva, Lyubov; Mingot, José-Manuel

2003-01-01

Human immunodeficiency virus type 1 (HIV-1), like other lentiviruses, can infect non-dividing cells. This property depends on the active nuclear import of its intracellular reverse transcription complex (RTC). We have studied nuclear import of purified HIV-1 RTCs in primary macrophages and found that importin 7, an import receptor for ribosomal proteins and histone H1, is involved in the process. Nuclear import of RTCs requires, in addition, energy and the com ponents of the Ran system. Depletion of importin 7 from cultured cells by small interfering RNA inhibits HIV-1 infection. These results provide a new insight into the molecular mechanism for HIV-1 nuclear import and reveal potential targets for therapeutic intervention. PMID:12853482

IMPROVING THE REPORTING OF THERAPEUTIC EXERCISE INTERVENTIONS IN REHABILITATION RESEARCH.

Page, Phil; Hoogenboom, Barb; Voight, Michael

2017-04-01

The foundation of evidence-based practice lies in clinical research, which is based on the utilization of the scientific method. The scientific method requires that all details of the experiment be provided in publications to support replication of the study in order to evaluate and validate the results. More importantly, clinical research can only be translated into practice when researchers provide explicit details of the study. Too often, rehabilitation exercise intervention studies lack the appropriate detail to allow clinicians to replicate the exercise protocol in their patient populations. Therefore, the purpose of this clinical commentary is to provide guidelines for optimal reporting of therapeutic exercise interventions in rehabilitation research. 5.

Quality of life (QoL) is a patient-reported outcome frequently included in Parkinson's disease (PD) clinical trials as a secondary or tertiary endpoint. However, QoL is an important variable that reflects the impact of disease and treatment from the patients' perspective. In a chronic, neurodegenerative disease such as PD, with a wide range of complex symptoms, QoL provides valuable and comprehensive information on the patients' health status. This narrative review aims to evaluate the effect of specific PD treatments currently in use on patients' QoL measured with the Parkinson's Disease Questionnaire, 39-item (PDQ-39) or 8-item (PDQ-8) version. A quantification of this effect is provided by calculation of the relative change and effect size. These two parameters allow an intuitive standardized approach to the importance of change based on its magnitude. Some high-quality studies (Level I) were found for levodopa (immediate- or extended-release formulations), levodopa with added-on catechol-O-methyltransferase (COMT) inhibitors, levodopa/carbidopa gel for intestinal infusion, some dopamine agonists (ropinirole, cabergoline, pergolide), and the monoamine oxidase B (MAO-B) inhibitor safinamide. As a whole, these studies found a beneficial effect of variable magnitude, weak to moderate, on patients' QoL. Studies with a lower level of evidence or not providing enough data to estimate relative change and effect size, including those for the apomorphine subcutaneous pump, also reported improvement of QoL, but the evidence was insufficient to confirm the effect. More high-quality studies focused on QoL are needed to determine the real impact of PD drug treatments for this important outcome.

Health outcomes research has gained considerable traction over the past decade as the medical community attempts to move beyond traditional outcome measures such as morbidity and mortality. Since its inception in 2009, the BREAST-Q has provided meaningful and reliable information regarding health-related quality of life (HRQOL) and patient satisfaction for use in both clinical practice and research. In this study, we review how researchers have used the BREAST-Q and how it has enhanced our understanding and practice of plastic and reconstructive breast surgery. An electronic literature review was performed to identify publications that used the BREAST-Q to assess patient outcomes. Studies developing and/or validating the BREAST-Q or an alternate patient-reported outcome measure (PROM), review papers, conference abstracts, discussions, comments and/or responses to previously published papers, studies that modified a version of BREAST-Q, and studies not published in English were excluded. Our literature review yielded 214 unique articles, 49 of which met our inclusion criteria. Important trends and highlights were further examined. The BREAST-Q has provided important insights into breast surgery highlighted by literature concerning autologous reconstruction, implant type, fat grafting, and patient education. The BREAST-Q has increased the use of PROMs in breast surgery and provided numerous important insights in its brief existence. The increased interest in PROMs as well as the underutilized potential of the BREAST-Q should permit its continued use and ability to foster innovations and improve quality of care.

Swaziland has made great progress towards its goal of malaria elimination by 2015. However, malaria importation from neighbouring high-endemic Mozambique through Swaziland's eastern border remains a major factor that could prevent elimination from being achieved. In order to reach elimination, Swaziland must rapidly identify and treat imported malaria cases before onward transmission occurs. A nationwide formative assessment was conducted over eight weeks to determine if the imported cases of malaria identified by the Swaziland National Malaria Control Programme could be linked to broader social networks and to explore methods to access these networks. Using a structured format, interviews were carried out with malaria surveillance agents (6), health providers (10), previously identified imported malaria cases (19) and people belonging to the networks identified through these interviews (25). Most imported malaria cases were Mozambicans (63%, 12/19) making a living in Swaziland and sustaining their families in Mozambique. The majority of imported cases (73%, 14/19) were labourers and self-employed contractors who travelled frequently to Mozambique to visit their families and conduct business. Social networks of imported cases with similar travel patterns were identified through these interviews. Nearly all imported cases (89%, 17/19) were willing to share contact information to enable network members to be interviewed. Interviews of network members and key informants revealed common congregation points, such as the urban market places in Manzini and Malkerns, as well as certain bus stations, where people with similar travel patterns and malaria risk behaviours could be located and tested for malaria. This study demonstrated that imported cases of malaria belonged to networks of people with similar travel patterns. This study may provide novel methods for screening high-risk groups of travellers using both snowball sampling and time-location sampling of networks to identify and treat additional malaria cases. Implementation of a proactive screening programme of importation networks may help Swaziland halt transmission and achieve malaria elimination by 2015.

Mapping forest tree species over large areas with partially cloudy Landsat imagery

Turlej, K.; Radeloff, V.

Forests provide numerous services to natural systems and humankind, but which services forest provide depends greatly on their tree species composition. That makes it important to track not only changes in forest extent, something that remote sensing excels in, but also to map tree species. The main goal of our work was to map tree species with Landsat imagery, and to identify how to maximize mapping accuracy by including partially cloudy imagery. Our study area covered one Landsat footprint (26/28) in Northern Wisconsin, USA, with temperate and boreal forests. We selected this area because it contains numerous tree species and variable forest composition providing an ideal study area to test the limits of Landsat data. We quantified how species-level classification accuracy was affected by a) the number of acquisitions, b) the seasonal distribution of observations, and c) the amount of cloud contamination. We classified a single year stack of Landsat-7, and -8 images data with a decision tree algorithm to generate a map of dominant tree species at the pixel- and stand-level. We obtained three important results. First, we achieved producer's accuracies in the range 70-80% and user's accuracies in range 80-90% for the most abundant tree species in our study area. Second, classification accuracy improved with more acquisitions, when observations were available from all seasons, and is the best when images with up to 40% cloud cover are included. Finally, classifications for pure stands were 10 to 30 percentage points better than those for mixed stands. We conclude that including partially cloudy Landsat imagery allows to map forest tree species with accuracies that were previously only possible for rare years with many cloud-free observations. Our approach thus provides important information for both forest management and science.

Meanings and aspects of quality of life for cancer patients: a descriptive exploratory qualitative study.

Given the importance of quality of life (QoL) for cancer patients, it is important to work out what this concept means not only for cancer patients, and for the nurses who care for them, but also the aspects of which it is composed. Therefore, an interpretive research study was conducted to explore in-depth meanings and aspects of QoL as expressed by cancer nurses. Participants were selected from different inpatient and outpatient oncology services and a palliative setting in Adelaide, South Australia. Results showed that many aspects contribute to an individual's QoL. These include the physical, the psychological, the spiritual, and both environmental and social interactions. More importantly, participants stated that spirituality is multifaceted and that there may be aspects in life that may be taken for granted. The meaning of patients' QoL was viewed by nurses as a patient's overall happiness and satisfaction. Also, nurses identified that providing choices to patients made an important contribution to a patient's QoL. Therefore, this exploration into the in-depth meanings and aspects of QoL for cancer patients from nurses' perspectives identified that, in addition to the aspects related to QoL that have been identified previously in the literature, aspects related to spirituality would need to be extensively covered, and providing choices to patients would be important in patients' QoL in an Australian setting.

Older adults with chronic pain who seek treatment often are in a health care environment that emphasizes patient-directed care, a change from the patriarchal model of care to which many older adults are accustomed. To explore the experiences of older adults seeking treatment for chronic pain, with respect to patient-directed care and the patient-provider relationship. In-depth interviews with 15 Caucasian older adults with chronic pain who had been evaluated at a university-based pain clinic. All interviews were audiotaped and the transcripts were analyzed using a grounded theory based approach. Older adults with chronic pain vary in their willingness to be involved in their treatment decisions. Many frequently participate in decisions about their pain treatment by asking for or refusing specific treatments, demanding quality care, or operating outside of the patient-provider relationship to manage pain on their own. However, others prefer to let their provider make the decisions. In either case, having a mutually respectful patient-provider relationship is important to this population. Specifically, participants described the importance of "being heard" and "being understood" by providers. As some providers switch from a patriarchal model of care toward a model of care that emphasizes patient activation and patient-centeredness, the development and cultivation of valued patient-provider relationships may change. While it is important to encourage patient involvement in treatment decisions, high-quality, patient-centered care for older adults with chronic pain should include efforts to strengthen the patient-provider relationship by attending to differences in patients' willingness to engage in patient-directed care and emphasizing shared decision-making.

In a world of generalized floating exchange rates, it is not enough to solve the problem of exchange rate policy by determining whether to peg or float the currency under consideration. It is also necessary to choose to what major currency to peg. The main purpose of this study is to investigate and determine empirically the optimum currency peg for the Saudi riyal. To accomplish this goal, a simple conventional trade model, that includes variables found in many other studies of import and export demand, was used. In addition, an exchange rate term was added as a separate independent variablemore » in the import and export demand equations in order to assess the effect of exchange rate on the trade flows. The criteria for the optimal currency peg in this study were based on two factors. First, the error statistics for projected imports and exports using alternative exchange rate regimes. Second, variances of projected imports, exports and trade balance using alternative exchange rate regimes. The exchange rate has a significant impact on the Saudia Arabian trade flows which implies that changes in the riyals value affect the Saudi trade deficit. Moreover, the exchange rate has a more powerful effect on its aggregate imports than on the world demand for its exports. There is also a strong support for the hypothesis that the exchange rate affects the value of the Saudi bilateral trade with its five major trade partners. On the aggregate level, the SDR peg seems to be the best currency peg for the Saudi riyal since it provides the best prediction errors and the lowest variance for the trade balance. Finally, on the disaggregate level, the US dollar provides the best performance and yields the best results among all the six currency pegs considered in this study.« less

Diatoms can be an important exception to temperature-size rules at species and community levels of organization.

Climate warming has been linked to an apparent general decrease in body sizes of ectotherms, both across and within taxa, especially in aquatic systems. Smaller body size in warmer geographical regions has also been widely observed. Since body size is a fundamental determinant of many biological attributes, climate-warming-related changes in size could ripple across multiple levels of ecological organization. Some recent studies have questioned the ubiquity of temperature-size rules, however, and certain widespread and abundant taxa, such as diatoms, may be important exceptions. We tested the hypothesis that diatoms are smaller at warmer temperatures using a system of geothermally heated streams. There was no consistent relationship between size and temperature at either the population or community level. These field data provide important counterexamples to both James' and Bergmann's temperature-size rules, respectively, undermining the widely held assumption that warming favours the small. This study provides compelling new evidence that diatoms are an important exception to temperature-size rules for three reasons: (i) we use many more species than prior work; (ii) we examine both community and species levels of organization simultaneously; (iii) we work in a natural system with a wide temperature gradient but minimal variation in other factors, to achieve robust tests of hypotheses without relying on laboratory setups, which have limited realism. In addition, we show that interspecific effects were a bigger contributor to whole-community size differences, and are probably more ecologically important than more commonly studied intraspecific effects. These findings highlight the need for multispecies approaches in future studies of climate warming and body size. © 2013 John Wiley & Sons Ltd.

With Parkinson's disease (PD) prevalence rates steadily increasing and long-term adherence to regular physical activity and exercise often difficult to achieve, it is imperative to investigate factors promoting adherence to secondary prevention programs (SPP) that help limit the progression of motor and nonmotor signs and symptoms of the disease. Caring interactions between patients and their rehabilitation team may be particularly germane to individuals with PD, given the physical and psychosocial issues that often accompany this disease (eg, loss of physical function, depression, apathy, and cognitive impairments). Considering this reasoning, the purpose of the present study was twofold: (1) to gain a better understanding of the nature of caring in an SPP setting from a patient perspective and (2) to discover what implications, if any, caring has on relevant patient-centered behaviors such as effort and adherence to SPPs. Ten individuals with PD were recruited. In-depth, qualitative interviews were performed using a semistructured interview guide. Inductive content analysis was used to identify themes representing participants' experiences of caring in the SPP setting. Six themes emerged from the data analysis. The first 4 themes described how rehabilitation providers fostered caring in the SPP setting: showing interest, creating a supportive atmosphere, benevolence, and paying attention. Participants described instances when rehabilitation providers (physical therapy assistants, physical therapy students, and exercise specialists) showed interest by asking personal questions and remembering personal information. A supportive environment was facilitated by making participants feel supported, welcomed, and valued. Benevolence was apparent when rehabilitation providers demonstrated kindness and approached their work as "more than just a job." Finally, the importance of feeling that rehabilitation providers "paid attention" to patients by giving them undivided consideration and by aiding with exercises was emphasized. This latter finding is akin to Nodding's concept of "engrossment," a key component of caring, which may be an important issue in the face of increasing use of technological devices (eg, laptop computers and i-pads) that may unintentionally direct rehabilitation providers' attention away from their patients. The final 2 themes-rehabilitation attendance and rehabilitation effort-pertaining to aim 2 of the study, are novel in underscoring the importance of caring with respect to patient behaviors. Several practical implications can be gleaned from the current study including (but not limited to) remembering personal information about the patient, providing patients with undivided attention, providing support for patients, and making patients feel welcome. These findings underscore the importance of addressing affective skills in training future rehabilitation practitioners. Findings also reveal salient implications associated with caring, namely enhanced rehabilitation attendance and effort. Finally, results highlight the need to examine the generalizability of caring elements identified in the current study and to quantitatively assess caring antecedents and outcomes in SPP settings.

Systematic Reviews (SRs) are an essential part of evidence-based medicine, providing support for clinical practice and policy on a wide range of medical topics. However, producing SRs is resource-intensive, and progress in the research they review leads to SRs becoming outdated, requiring updates. Although the question of how and when to update SRs has been studied, the best method for determining when to update is still unclear, necessitating further research. In this work we study the potential impact of a machine learning-based automated system for providing alerts when new publications become available within an SR topic. Some of these new publications are especially important, as they report findings that are more likely to initiate a review update. To this end, we have designed a classification algorithm to identify articles that are likely to be included in an SR update, along with an annotation scheme designed to identify the most important publications in a topic area. Using an SR database containing over 70,000 articles, we annotated articles from 9 topics that had received an update during the study period. The algorithm was then evaluated in terms of the overall correct and incorrect alert rate for publications meeting the topic inclusion criteria, as well as in terms of its ability to identify important, update-motivating publications in a topic area. Our initial approach, based on our previous work in topic-specific SR publication classification, identifies over 70% of the most important new publications, while maintaining a low overall alert rate. We performed an initial analysis of the opportunities and challenges in aiding the SR update planning process with an informatics-based machine learning approach. Alerts could be a useful tool in the planning, scheduling, and allocation of resources for SR updates, providing an improvement in timeliness and coverage for the large number of medical topics needing SRs. While the performance of this initial method is not perfect, it could be a useful supplement to current approaches to scheduling an SR update. Approaches specifically targeting the types of important publications identified by this work are likely to improve results.

Neurocysticercosis, the central nervous system's localised form of cysticercosis, is considered to be the leading cause of epilepsy in the developing world. In Europe, the disease is mainly imported and affects both immigrants and travellers. However, autochthonous cases of cysticercosis in low-endemic countries could also originate from Taenia solium carriers (migrants or travellers) who acquired taeniasis overseas. Management of cysticercosis is a challenge for European healthcare providers as they are often hardly aware of this infection and have little familiarity in managing this disease. This study provides a summary of recommendations concerning screening, diagnosis and management of cysticercosis and T. solium taeniasis in Europe drawn up by nine experts in migrant health and imported diseases with experience in cysticercosis and T. solium taeniasis. © 2017 John Wiley & Sons Ltd.

Groundwater plays a critical and important role in world's freshwater resources and it is also an important part of Taiwan's water supply for domestic, agricultural and industrial use. Prolonged dry climatic conditions can induce groundwater drought and may have huge impact on water resources. Therefore, this study utilizes seasonal rainfall forecasts from the Model for Prediction Across Scales (MPAS) to simulate groundwater levels in Lanyang Plain in Taiwan up to three months into future. The MPAS is setup with 120 km uniform grid and the physics schemes including WSM6 micorphysics scheme, Kain-Fritsch cumulus scheme, RRTMG radiation scheme, and YSU planetary boundary layer scheme are used to provide the rainfall forecasts. Results of this study can provide a reference for water resources management to ensure the sustainability of groundwater resources in Lanyang Plain.

For non-stationary processes, the time-varying correlation structure provides useful insights into the underlying model dynamics. We study estimation and inferences for local autocorrelation process in locally stationary time series. Our constructed simultaneous confidence band can be used to address important hypothesis testing problems, such as whether the local autocorrelation process is indeed time-varying and whether the local autocorrelation is zero. In particular, our result provides an important generalization of the R function acf() to locally stationary Gaussian processes. Simulation studies and two empirical applications are developed. For the global temperature series, we find that the local autocorrelations are time-varying and have a "V" shape during 1910-1960. For the S&P 500 index, we conclude that the returns satisfy the efficient-market hypothesis whereas the magnitudes of returns show significant local autocorrelations.

Animal models are an important resource for studying human diseases. Genetically engineered mice are the most commonly used species and have made significant contributions to our understanding of basic biology, disease mechanisms, and drug development. However, they often fail to recreate important aspects of human diseases and thus can have limited utility as translational research tools. Developing disease models in species more similar to humans may provide a better setting in which to study disease pathogenesis and test new treatments. This unit provides an overview of the history of genetically engineered large animals and the techniques that have made their development possible. Factors to consider when planning a large animal model, including choice of species, type of modification and methodology, characterization, production methods, and regulatory compliance, are also covered. © 2016 by John Wiley & Sons, Inc.

Receiver operating characteristic analysis provides an important methodology for assessing traditional (e.g., imaging technologies and clinical practices) and new (e.g., genomic studies, biomarker development) diagnostic problems. The area under the clinically/practically relevant part of the receiver operating characteristic curve (partial area or partial area under the receiver operating characteristic curve) is an important performance index summarizing diagnostic accuracy at multiple operating points (decision thresholds) that are relevant to actual clinical practice. A robust estimate of the partial area under the receiver operating characteristic curve is provided by the area under the corresponding part of the empirical receiver operating characteristic curve. We derive a closed-form expression for the jackknife variance of the partial area under the empirical receiver operating characteristic curve. Using the derived analytical expression, we investigate the differences between the jackknife variance and a conventional variance estimator. The relative properties in finite samples are demonstrated in a simulation study. The developed formula enables an easy way to estimate the variance of the empirical partial area under the receiver operating characteristic curve, thereby substantially reducing the computation burden, and provides important insight into the structure of the variability. We demonstrate that when compared with the conventional approach, the jackknife variance has substantially smaller bias, and leads to a more appropriate type I error rate of the Wald-type test. The use of the jackknife variance is illustrated in the analysis of a data set from a diagnostic imaging study.

The Chernobyl accident — an epidemiological perspective

Cardis, E.; Hatch, M.

Twenty-five years have passed since radioactive releases from the Chernobyl nuclear accident led to exposure of millions of people in Europe. Studies of affected populations have provided important new data on the links between radiation and cancer – particularly the risk of thyroid tumours from exposure to iodine isotopes - that are important not only for a fuller scientific understanding of radiation effects, but also for radiation protection. It is now well-documented that children and adolescents exposed to radioiodines from Chernobyl fallout have a sizeable dose-related increase in thyroid cancer, with risk greatest in those youngest at exposure and with a suggestion that deficiency in stable iodine may increase the risk. Data on thyroid cancer risks to other age groups are somewhat less definitive. In addition, there have been reported increases in incidence and mortality from non-thyroid cancers and non-cancer endpoints. Although some studies are difficult to interpret because of methodological limitations, recent investigations of Chernobyl clean-up workers (“liquidators”) have provided evidence of increased risks of leukaemia and other hematological malignancies and of cataracts, and suggestions of an increase in risk of cardiovascular diseases, following low doses and low dose rates of radiation. Further careful follow-up of these populations, including establishment and long-term support of life-span study cohorts, could provide additional important information for the quantification of radiation risks and the protection of persons exposed to low doses of radiation.

Examination of cultural competence in service providers in an early intervention programme for psychosis in Montreal, Quebec: Perspectives of service users and treatment providers.

PubMed

Venkataraman, Shruthi; Jordan, Gerald; Pope, Megan A; Iyer, Srividya N

2018-06-01

To better understand cultural competence in early intervention for psychosis, we compared service users' and service providers' perceptions of the importance of providers being culturally competent and attentive to aspects of culture. At a Canadian early intervention programme, a validated scale was adapted to assess service user (N = 51) and provider (N = 30) perceptions of service providers' cultural competence and the importance accorded thereto. Analyses of variance revealed that the importance of service providers being culturally competent was rated highest by service providers, followed by visible minority service users, followed by white service users. Providers rated themselves as being more interested in knowing about service users' culture than service users perceived them to be. Service users accorded less import to service providers' cultural competence than providers themselves, owing possibly to varied socialization. A mismatch in users' and providers' views on providers' efforts to know their users' cultures may influence mental healthcare outcomes. © 2017 John Wiley & Sons Australia, Ltd.

Despite growing recognition that mineral sites restored for nature conservation can enhance local biodiversity, the wider societal benefits provided by this type of restoration relative to alternative options are not well understood. This study addresses this research gap by quantifying differences in ecosystem services provision under two common mineral site after-uses: nature conservation and agriculture. Using a combination of site-specific primary field data, benefits transfer and modelling, we show that for our sites restoration for nature conservation provides a more diverse array of ecosystem services than would be delivered under an agricultural restoration scenario. We also explore the effects of addressing different conservation targets, which we find alter the provision of ecosystem services on a service-specific basis. Highly species-focused intervention areas are associated with increased carbon storage and livestock grazing provision, whereas non-intervention areas are important for carbon sequestration, fishing, recreation and flood risk mitigation. The results of this study highlight the wider societal importance of restored mineral sites and may help conservation managers and planners to develop future restoration strategies that provide benefits for both biodiversity and human well-being.

Illness blogs are a way seriously ill people communicate publicly about their illness journey. As communication about serious illness increases on social media, it is important to evaluate how this affects the family caregiver. However, identifying and accessing family caregivers remains challenging, especially via social media. The aim of this article is to report the opportunities, challenges and lessons learned from using social media to recruit family caregivers. Recruitment methods included posting study invitations on illness blogs, advertising through Facebook and placing study fliers in the community. Using social media to recruit was inexpensive and provided a wide geographical reach. One important finding was discovering the importance of using language in the recruitment materials that family caregivers could identify with to help deem themselves as eligible to participate in the study.

Aja, Godwin N; Modeste, Naomi N; Lee, Jerry W; Montgomery, Susanne; Belliard, Juan C

This study explored the extent to which church members thought the assets they might have to engage in HIV/AIDS prevention and control activities were important. Eight hundred and thirty members from 83 Christian churches in Aba, Nigeria completed a multi-item survey questionnaire designed to obtain information on the importance they attached to church-based assets relevant to HIV/AIDS prevention and control. The rating of importance of assets was on a scale of 1 to 5. Rating on the importance of assets was highest in the spiritual asset category (mean = 4.20), followed by health education (4.02), capacity building (4.01), social (3.62), and financial assets (3.54). Among the denominational assets, free HIV/AIDS drug donation was rated higher (4.10) than other assets in the subcategories. This study demonstrates the usefulness of ascertaining members' perspectives on the importance of church-based assets and provides a basis for recommendation to health education administrators.

Aerosol-cloud interactions in Arctic mixed-phase stratocumulus

NASA Astrophysics Data System (ADS)

Solomon, A.

2017-12-01

Reliable climate projections require realistic simulations of Arctic cloud feedbacks. Of particular importance is accurately simulating Arctic mixed-phase stratocumuli (AMPS), which are ubiquitous and play an important role in regional climate due to their impact on the surface energy budget and atmospheric boundary layer structure through cloud-driven turbulence, radiative forcing, and precipitation. AMPS are challenging to model due to uncertainties in ice microphysical processes that determine phase partitioning between ice and radiatively important cloud liquid water. Since temperatures in AMPS are too warm for homogenous ice nucleation, ice must form through heterogeneous nucleation. In this presentation we discuss a relatively unexplored source of ice production-recycling of ice nuclei in regions of ice subsaturation. AMPS frequently have ice-subsaturated air near the cloud-driven mixed-layer base where falling ice crystals can sublimate, leaving behind IN. This study provides an idealized framework to understand feedbacks between dynamics and microphysics that maintain phase-partitioning in AMPS. In addition, the results of this study provide insight into the mechanisms and feedbacks that may maintain cloud ice in AMPS even when entrainment of IN at the mixed-layer boundaries is weak.

Ligand-guided optimization of CXCR4 homology models for virtual screening using a multiple chemotype approach

Neves, Marco A. C.; Simões, Sérgio; Sá e Melo, M. Luisa

2010-12-01

CXCR4 is a G-protein coupled receptor for CXCL12 that plays an important role in human immunodeficiency virus infection, cancer growth and metastasization, immune cell trafficking and WHIM syndrome. In the absence of an X-ray crystal structure, theoretical modeling of the CXCR4 receptor remains an important tool for structure-function analysis and to guide the discovery of new antagonists with potential clinical use. In this study, the combination of experimental data and molecular modeling approaches allowed the development of optimized ligand-receptor models useful for elucidation of the molecular determinants of small molecule binding and functional antagonism. The ligand-guided homology modeling approach used in this study explicitly re-shaped the CXCR4 binding pocket in order to improve discrimination between known CXCR4 antagonists and random decoys. Refinement based on multiple test-sets with small compounds from single chemotypes provided the best early enrichment performance. These results provide an important tool for structure-based drug design and virtual ligand screening of new CXCR4 antagonists.

Data on food sources of nutrients are needed to improve strategies to enhance nutrient intake among girls and boys in Western countries. To identify major food sources of energy, energy nutrients, dietary fibre, and micronutrients, and to study gender differences in these food sources among children. We assessed food consumption and nutrient intake using 4-day food records in a population sample of Finnish girls ( n =213) and boys ( n =217) aged 6-8 years from the Physical Activity and Nutrition in Children Study. We calculated the percentual contribution of 55 food groups for energy and nutrient intake using the population proportion method. Low-fibre grain products, skimmed milk, and high-fibre bread provided almost 23% of total energy intake. Skimmed milk was the top source of protein (18% of total intake), vitamin D (32%), potassium (20%), calcium (39%), magnesium (17%), and zinc (16%). Vegetable oils (15%) and high-fat vegetable oil-based spreads (14%) were the top sources of polyunsaturated fat. High-fibre bread was the top source of fibre (27%) and iron (12%). Non-root vegetables were the top source of folate (14%) and vitamin C (22%). Sugar-sweetened beverages provided 21% of sucrose intake. Pork was a more important source of protein and sausage was a more important source of total fat and monounsaturated fat in boys than in girls. Vegetable oils provided a higher proportion of unsaturated fat and vitamin E among boys, whereas high-fat vegetable oil-based spreads provided a higher proportion of these nutrients among girls. Commonly recommended foods, such as skimmed milk, high-fibre grain products, vegetables, vegetable oil, and vegetable oil-based spreads, were important sources of several nutrients, whereas sugar-sweetened beverages provided the majority of sucrose intake among children. This knowledge can be used in improving health among children by dietary interventions, nutrition education, and health policy decision making.

Metagenomic and Metatranscriptomic Analyses Reveal the Structure and Dynamics of a Dechlorinating Community Containing Dehalococcoides mccartyi and Corrinoid-Providing Microorganisms under Cobalamin-Limited Conditions

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

Men, Yujie; Yu, Ke; Bælum, Jacob

ABSTRACT The aim of this study is to obtain a systems-level understanding of the interactions betweenDehalococcoidesand corrinoid-supplying microorganisms by analyzing community structures and functional compositions, activities, and dynamics in trichloroethene (TCE)-dechlorinating enrichments. Metagenomes and metatranscriptomes of the dechlorinating enrichments with and without exogenous cobalamin were compared. Seven putative draft genomes were binned from the metagenomes. At an early stage (2 days), more transcripts of genes in theVeillonellaceaebin-genome were detected in the metatranscriptome of the enrichment without exogenous cobalamin than in the one with the addition of cobalamin. Among these genes, sporulation-related genes exhibited the highest differential expression when cobalamin wasmore » not added, suggesting a possible release route of corrinoids from corrinoid producers. Other differentially expressed genes include those involved in energy conservation and nutrient transport (including cobalt transport). The most highly expressed corrinoidde novobiosynthesis pathway was also assigned to theVeillonellaceaebin-genome. Targeted quantitative PCR (qPCR) analyses confirmed higher transcript abundances of those corrinoid biosynthesis genes in the enrichment without exogenous cobalamin than in the enrichment with cobalamin. Furthermore, the corrinoid salvaging and modification pathway ofDehalococcoideswas upregulated in response to the cobalamin stress. This study provides important insights into the microbial interactions and roles played by members of dechlorinating communities under cobalamin-limited conditions. IMPORTANCEThe key chloroethene-dechlorinating bacteriumDehalococcoides mccartyiis a cobalamin auxotroph, thus acquiring corrinoids from other community members. Therefore, it is important to investigate the microbe-microbe interactions betweenDehalococcoidesand the corrinoid-providing microorganisms in a community. This study provides systems-level information, i.e., taxonomic and functional compositions and dynamics of the supportive microorganisms in dechlorinating communities under different cobalamin conditions. The findings shed light on the important roles ofVeillonellaceaespecies in the communities compared to other coexisting community members in producing and providing corrinoids forDehalococcoidesspecies under cobalamin-limited conditions.« less

Waldrop, Deborah P; McGinley, Jacqueline M; Clemency, Brian

2018-04-09

Nursing home (NH) residents account for over 2.2 million emergency department visits yearly; the majority are cared for and transported by prehospital providers (emergency medical technicians and paramedics). The purpose of this study was to investigate prehospital providers' perceptions of emergency calls at life's end. This article focuses on perceptions of end-of-life calls in long-term care (LTC). This pilot study employed a descriptive cross-sectional design. Concepts from the symbolic interaction theory guided the exploration of perceptions and interpretations of emergency calls in LTC facilities. A purposeful sample of prehospital providers was developed from one agency in a small northeastern U.S. city. Semistructured interviews were conducted with 43 prehospital providers to explore their perceptions of factors that trigger emergency end-of-life calls in LTC facilities. Qualitative data analysis involved iterative coding in an inductive process that included open, systematic, focused, and axial coding. Interview themes illustrated the contributing factors as follows: care crises; dying-related turmoil; staffing ratios; and organizational protocols. Distress was crosscutting and present in all four themes. The findings illuminate how prehospital providers become mediators between NHs and emergency departments by managing tension, conflict, and challenges in patient care between these systems and suggest the importance of further exploration of interactions between LTC staff, prehospital providers, and emergency departments. Enhanced communication between LTC facilities and prehospital providers is important to address potentially inappropriate calls and transport requests and to identify means for collaboration in the care of sick frail residents.

Coincidence detection and crosstalk between signal transduction systems play very important regulatory roles in the nervous system, particularly in the regulation of transcription. Coupling of the Ca2+ and cAMP regulatory systems by calmodulin-regulated adenylyl cyclases is hypothesized to be important for some forms of synaptic plasticity, neuroendocrine function, and olfactory detection. Recent studies of a mutant mouse deficient in type I calmodulin-sensitive adenylyl cyclase have provided the first evidence that adenylyl cyclases are important for synaptic plasticity, as well as for learning and memory in vertebrates.

Brunett, Miranda; Shingles, René Revis

2018-04-23

Clinical Scenario: The level of cultural competence of health care providers has been studied. However, limited scholarship has examined whether the cultural competence of the health care provider affects patient satisfaction. Focused Clinical Question: Does cultural competence of health care providers influence patient satisfaction with their experience with their provider? Summary of Key Findings: Having a culturally competent health care provider, or one who a patient perceives as culturally competent, does increase patient satisfaction. Clinical Bottom Line: Cultural competence in health care plays an important role in patients being satisfied with their providers, as well as patients willingly and actively participating in their treatment. Strength of Recommendation: Questions 1 to 5 and 9 of the critical appraisal skills program were answered "yes" for all studies in the critically appraised topic. Thus, the authors strongly support the findings.

Questions of existence of the "China Route" for drug smuggling and trafficking have been important in the literature. The profile of the offenders, particularly whether they are primarily members of traditional criminal organization, is a hotly debated issue. Much qualitative evidence has been collected and it provides important insights into these questions. However, little quantitative data has ever been collected and analyzed to provide a broader picture of these issues. The present study involves the systematical collection of data from court sentencing files from seven high courts whose jurisdictions cover the China Route. The findings provide valuable information that sheds light on the debated questions. Some evidence consistent with the China Route arguments is found. No evidence supports the idea that traditional organized criminal syndicates are behind most offenses. Logistic regression results reveal interesting associations between offender characteristics and types of offenses.

Symbiosis of Steel, Energy, and CO2 Evolution in Korea

This study looks at the energy intensity of the steel industry and the greenhouse gas intensity involved with the production of steel. Using several sources of steel production data and the corresponding energy sources used provides a time-series analysis of the greenhouse gas (GHG) and energy intensity from 1990 to 2014. The impact of the steel economy with the gross domestic product (GDP) provides indirect importance of the general manufacturing sector within Korea and in particular the steel industry. Beyond 2008, the shift in excess materials production and significant increase in total imports have led to an imbalance in the Korean steel market and continue to inhibit the growth of the domestic steel market. The forecast of the GHG and energy intensity along with the steel production up to 2030 is provided using the auto regressive integrated moving average analysis.

The importance of genes in regulating phenotypic variation of personality traits in humans and animals is becoming increasingly apparent in recent studies. Here we focus on variation in the vasopressin receptor gene 1a (Avpr1a) and oxytocin receptor gene (OXTR) and their effects on social personality traits in chimpanzees. We combine newly available genetic data on Avpr1a and OXTR allelic variation of 62 captive chimpanzees with individual variation in personality, based on behavioral assessments. Our study provides support for the positive association of the Avpr1a promoter region, in particular the presence of DupB, and sociability in chimpanzees. This complements findings of previous studies on adolescent chimpanzees and studies that assessed personality using questionnaire data. In contrast, no significant associations were found for the single nucleotide polymorphism (SNP) ss1388116472 of the OXTR and any of the personality components. Most importantly, our study provides additional evidence for the regulatory function of the 5' promoter region of Avpr1a on social behavior and its evolutionary stable effect across species, including rodents, chimpanzees and humans. Although it is generally accepted that complex social behavior is regulated by a combination of genes, the environment and their interaction, our findings highlight the importance of candidate genes with large effects on behavioral variation.

The objective of this study was to discuss ideas for improving child health services on the basis of findings of an observational study that was designed to explore the role of child health nurses in supporting parents during the first 6 months following the birth of an infant. As part of a larger study in a child health service in urban Australia, surveys were used to collect data from two independent samples of both parents and nurses at an 8-month interval. Data were condensed using factor analysis; regression analyses were used to determine which aspects of care were most important for the parents, and importance-performance analysis was used to determine which aspects of care needed improvement. While the majority of parents valued support from child health nurses, a need for improvement was identified in empowering parents to make their own decisions, discussing emotional issues with parents, providing continuity of care and giving consistent advice. Organisations should value and provide support for child health nurses in their invisible, non-quantifiable work of supporting families. The structure of child health services should also provide child health nurses continuity of care with the families they support.

Healthcare system responses to intimate partner violence in low and middle-income countries: evidence is growing and the challenges become clearer.

2017-07-12

The damage to health caused by intimate partner violence demands effective responses from healthcare providers and healthcare systems worldwide. To date, most evidence for the few existing, effective interventions in use comes from high-income countries. Gupta et al. provide rare evidence of a nurse-delivered intimate partner violence screening, supportive care and referral intervention from a large-scale randomised trial in Mexican public health clinics. No difference was found in the primary outcome of reduction in intimate partner violence. There were significant short-term benefits in safety planning and mental health (secondary outcomes) for women in the intervention arm, but these were not sustained.This important study highlights the challenges of primary outcome choices in such studies, and further challenges for the sustainability of healthcare systems and healthcare provider interventions. These challenges include the role of theory for sustainability and the risk that baseline measures of intimate partner violence can wash out intervention effects. We emphasise the importance of studying the processes of adaptation, integration and coordination in the context of the wider healthcare system.Please see related article: https://bmcmedicine.biomedcentral.com/articles/10.1186/s12916-017-0880-y.

Job satisfaction is an important factor in health care settings. Strong empirical evidence supports a causal relationship between job satisfaction, patient safety and quality of care. However, there have not been any studies exploring the job satisfaction of Malaysian nurses. The main purpose of this qualitative descriptive study was to explore the factors related to feelings of job satisfaction as well as job dissatisfaction experienced by registered nurses in Malaysia. A convenient sample of 46 Malaysian nurses recruited from a large hospital (number of beds = 895) participated in the study. A total of seven focus group discussions were conducted with nurses from surgical, medical and critical care wards. A semi-structured interview guide was used to facilitate the interviews, which were audio-recorded, transcribed verbatim and checked. The transcripts were used as data and were analysed using a thematic approach. The study identified three main themes that influenced job satisfaction: (1) nurses' personal values and beliefs; (2) work environment factors and (3) motivation factors. Concerning the nurses' personal values and beliefs, the ability to help people made the nurses felt honoured and happy, which indirectly contributed to job satisfaction. For work environment factors, team cohesion, benefit and reward, working conditions play an important role in the nurses' job satisfaction. Motivation factors, namely, professional development and clinical autonomy contributed to job satisfaction. It is important for nurse leaders to provide more rewards, comfortable work environments and to understand issues that affect nurses' job satisfaction. Our findings highlight the importance of factors that can improve nurses' job satisfaction. The study provides basic information for hospital administrators in planning effective and efficient policies to improve nursing job satisfaction in order to increase the quality of patient care and decrease nursing turnover. © 2014 British Association of Critical Care Nurses.

Clinicians face challenges in delivering care to socioeconomically disadvantaged patients. While both the public and academic sectors recognize the importance of addressing social inequities in healthcare, there is room for improvement in the training of family physicians, who report being ill-equipped to provide care that is responsive to the living conditions of these patients. This study explored: (i) residents' perceptions and experience in relation to providing care for socioeconomically disadvantaged patients, and (ii) how participating in a photovoice study helped them uncover and examine some of their prejudices and assumptions about poverty. We conducted a participatory photovoice study. Participants were four family medicine residents, two medical supervisors, and two researchers. Residents attended six photovoice meetings at which they discussed photos they had taken. In collaboration with the researchers, the participants defined the research questions, took photos, and participated in data analysis and results dissemination. Meetings were recorded and transcribed for analysis, which consisted of coding, peer debriefing, thematic analysis, and interpretation. The medical residents uncovered and examined their own prejudices and misconceptions about poverty. They reported feeling unprepared to provide care to socioeconomically disadvantaged patients. Supported by medical supervisors and researchers, the residents underwent a three-phase reflexive process of: (1) engaging reflexively, (2) break(ing) through, and (3) taking action. The results indicated that medical residents subsequently felt encouraged to adopt a care approach that helped them overcome the social distance between themselves and their socioeconomically disadvantaged patients. This study highlights the importance of providing medical training on issues related to poverty and increasing awareness about social inequalities in medical education to counteract prejudices toward socioeconomically disadvantaged patients. Future studies should examine which elective courses and training could provide suitable tools to clinicians to improve their competence in delivering care to socioeconomically disadvantaged patients.

Stress of conscience and perceptions of conscience in relation to burnout among care-providers in older people.

2008-07-01

The aim was to study the relationship between conscience and burnout among care-providers in older care, exploring the relationship between stress of conscience and burnout, and between perceptions of conscience and burnout. Everyday work in healthcare presents situations that influence care-providers' conscience. How care-providers perceive conscience has been shown to be related to stress of conscience (stress related to troubled conscience), and in county council care, an association between stress of conscience and burnout has been found. A questionnaire study was conducted in municipal housing for older people. A total of 166 care-providers were approached, of which 146 (50 registered nurses and 96 nurses' aides/enrolled nurses) completed a questionnaire folder containing the stress of conscience questionnaire, the perceptions of conscience questionnaire and the maslach burnout inventory. Multivariate canonical correlation analysis was used to explore relationships. The relationship between stress of conscience and burnout indicates that experiences of shortcomings and of being exposed to contradictory demands are strongly related to burnout (primarily to emotional exhaustion). The relationship between perceptions of conscience and burnout indicates that a deadened conscience is strongly related to burnout. Conscience seems to be of importance in relation to burnout, and suppressing conscience may result in a profound loss of wholeness, integrity and harmony in the self. The results from our study could be used to raise awareness of the importance of conscience in care.

A survey-based study of Zika virus communication preferences among pregnant women in Georgia, United States.

2017-09-26

Because of the particularly severe perinatal outcomes associated with antenatal Zika virus infection, it is important for prenatal care providers to communicate Zika virus risks and strategies for prevention to their patients. Although face-to-face communication is ideal, clinic visits may not allow for in-depth discussion of all concerns. While previous studies have shown prenatal providers to be pregnant women's most trusted sources of health information, there is little knowledge on what secondary communication modalities pregnant women prefer for receiving information from their providers about an evolving public health emergency. A cross-sectional, descriptive anonymous 27-item survey was distributed to pregnant women at four clinics around Atlanta, Georgia from May 5th to June 20th, 2016. The survey assessed women's interest in and communication preferences about prenatal topics, including Zika virus. Descriptive statistics were calculated and chi-square tests were used to evaluate associations between the primary outcomes and patient characteristics. Four-hundred and eight women completed the survey. The most popular resource for obtaining Zika virus information was the Centers for Disease Control and Prevention (CDC) website (73.0%). While their prenatal provider's own website for Zika information ranked 5th among sources currently accessed for Zika information, it ranked third behind educational brochures and emails for ways in which women wanted to receive information. The characteristics of Zika virus information deemed most important were: evidence-based (87.5%), endorsed by the CDC (74.1%), and endorsed by their own provider (67.9%). In any public health emergency affecting pregnant women, women are going to seek advice from their obstetric providers. Because providers may lack sufficient time to discuss concerns with every patient, they may consider providing patient education in other ways. For the women included in this study, educational brochures, emails and providers' own practice websites were preferred. Providers should consider taking greater advantage of these modalities to supplement in-person exchanges, particularly during a public health emergency.

Parent-provider communication during hospitalization.

Fisher, Mark J; Broome, Marion E

2011-02-01

Parents and health care providers interact and communicate with each other during a child's hospitalization. The purpose of this study was to compare communication experiences of parents, nurses, and physicians. A unique aspect of this study involved combining three individual data sources into a collective unit of study (triad). Triads involved in the care of three children in the inpatient setting of an urban children's hospital served as the sample for this study (n = 10). Participants were asked semistructured questions during face-to-face interviews. Findings included (a) the importance of providing information by health care providers using a caring and inclusive approach, (b) the benefits of establishing interpersonal connections and nurturing relationships, and (c) the identification of specific behaviors in all members of the triad that contribute to and sustain positively perceived communication. Future research directions examining triadic interactions, communication, and relationships among parents, nurses, and physicians are recommended. Copyright © 2011 Elsevier Inc. All rights reserved.

Digital imagery is important in many applications today, and the security of digital imagery is important today and is likely to gain in importance in the near future. The emerging international standard ISO/IEC JPEG-2000 Security (JPSEC) is designed to provide security for digital imagery, and in particular digital imagery coded with the JPEG-2000 image coding standard. One of the primary goals of a standard is to ensure interoperability between creators and consumers produced by different manufacturers. The JPSEC standard, similar to the popular JPEG and MPEG family of standards, specifies only the bitstream syntax and the receiver's processing, and not how the bitstream is created or the details of how it is consumed. This paper examines the interoperability for the JPSEC standard, and presents an example JPSEC consumption process which can provide insights in the design of JPSEC consumers. Initial interoperability tests between different groups with independently created implementations of JPSEC creators and consumers have been successful in providing the JPSEC security services of confidentiality (via encryption) and authentication (via message authentication codes, or MACs). Further interoperability work is on-going.

Paediatric status epilepticus (SE) is a medical emergency and a common critical condition confronting pre-hospital providers. Management in the pre-hospital environment is challenging but considered extremely important as a potentially modifiable factor on outcome. Recent data from multicentre clinical trials, quality observational studies and consensus documents have influenced management in this area, and is important to both pre-hospital providers and emergency physicians. The objective of this review was to: (i) present an overview of the available evidence relevant to pre-hospital care of paediatric SE; and (ii) assess the current pre-hospital practice guidelines in Australia and New Zealand. The review outlines current definitions and guidelines of SE management, regional variability in pre-hospital protocols within Australasia and aspects of pre-hospital care that could potentially be improved. Contemporary data is required to determine current practice in our setting. It is important that paediatric neurologists, emergency physicians and pre-hospital care providers are all engaged in future endeavours to improve clinical care and knowledge translation efforts for this patient group. © 2017 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

Coalescent: an open-science framework for importance sampling in coalescent theory.

PubMed

Tewari, Susanta; Spouge, John L

2015-01-01

Background. In coalescent theory, computer programs often use importance sampling to calculate likelihoods and other statistical quantities. An importance sampling scheme can exploit human intuition to improve statistical efficiency of computations, but unfortunately, in the absence of general computer frameworks on importance sampling, researchers often struggle to translate new sampling schemes computationally or benchmark against different schemes, in a manner that is reliable and maintainable. Moreover, most studies use computer programs lacking a convenient user interface or the flexibility to meet the current demands of open science. In particular, current computer frameworks can only evaluate the efficiency of a single importance sampling scheme or compare the efficiencies of different schemes in an ad hoc manner. Results. We have designed a general framework (http://coalescent.sourceforge.net; language: Java; License: GPLv3) for importance sampling that computes likelihoods under the standard neutral coalescent model of a single, well-mixed population of constant size over time following infinite sites model of mutation. The framework models the necessary core concepts, comes integrated with several data sets of varying size, implements the standard competing proposals, and integrates tightly with our previous framework for calculating exact probabilities. For a given dataset, it computes the likelihood and provides the maximum likelihood estimate of the mutation parameter. Well-known benchmarks in the coalescent literature validate the accuracy of the framework. The framework provides an intuitive user interface with minimal clutter. For performance, the framework switches automatically to modern multicore hardware, if available. It runs on three major platforms (Windows, Mac and Linux). Extensive tests and coverage make the framework reliable and maintainable. Conclusions. In coalescent theory, many studies of computational efficiency consider only effective sample size. Here, we evaluate proposals in the coalescent literature, to discover that the order of efficiency among the three importance sampling schemes changes when one considers running time as well as effective sample size. We also describe a computational technique called "just-in-time delegation" available to improve the trade-off between running time and precision by constructing improved importance sampling schemes from existing ones. Thus, our systems approach is a potential solution to the "2(8) programs problem" highlighted by Felsenstein, because it provides the flexibility to include or exclude various features of similar coalescent models or importance sampling schemes.

Consumer satisfaction with primary care provider choice and associated trust

PubMed Central

Chu-Weininger, Ming Ying L; Balkrishnan, Rajesh

2006-01-01

Background Development of managed care, characterized by limited provider choice, is believed to undermine trust. Provider choice has been identified as strongly associated with physician trust. Stakeholders in a competitive healthcare market have competing agendas related to choice. The purpose of this study is to analyze variables associated with consumer's satisfaction that they have enough choice when selecting their primary care provider (PCP), and to analyze the importance of these variables on provider trust. Methods A 1999 randomized national cross-sectional telephone survey conducted of United States residential households, who had a telephone, had seen a medical professional at least twice in the past two years, and aged ≥ 20 years was selected for secondary data analyses. Among 1,117 households interviewed, 564 were selected as the final sample. Subjects responded to a core set of questions related to provider trust, and a subset of questions related to trust in the insurer. A previously developed conceptual framework was adopted. Linear and logistic regressions were performed based on this framework. Results Results affirmed 'satisfaction with amount of PCP choice' was significantly (p < .001) associated with provider trust. 'PCP's care being extremely effective' was strongly associated with 'satisfaction with amount of PCP choice' and 'provider trust'. Having sought a second opinion(s) was associated with lower trust. 'Spoke to the PCP outside the medical office,' 'satisfaction with the insurer' and 'insurer charges less if PCP within network' were all variables associated with 'satisfaction with amount of PCP choice' (all p < .05). Conclusion This study confirmed the association of 'satisfaction with amount of PCP choice' with provider trust. Results affirmed 'enough PCP choice' was a strong predictor of provider trust. 'Second opinion on PCP' may indicate distrust in the provider. Data such as 'trust in providers in general' and 'the role of provider performance information' in choice, though import in PCP choice, were not available for analysis and should be explored in future studies. Results have implications for rethinking the relationships among consumer choice, consumer behaviors in making trade-offs in PCP choice, and the role of healthcare experiences in 'satisfaction with amount of PCP choice' or 'provider trust.'

In Mozambique, and other low-income countries (LICs), there is little information on the burden of child maltreatment (CM). Emergency care services (ECS) play an important role in recognizing, treating, and intervening in situations of CM. We aim to identify knowledge, attitudes, and practices regarding CM among health care providers in ECS at Mavalane General Hospital in Maputo, Mozambique. This exploratory cross-sectional study evaluates the knowledge, attitudes, and practices of health care providers to diagnose and treat cases of CM. A 25 min, pilot-tested verbal interview questionnaire was administered to 49 physicians and nurses working in ECS at Mavalane General Hospital. Interviews were completed between October-November 2010. Data were managed and analyzed in SPSS 14.0 and descriptive statistics were generated. Of 49 health care providers, 83.6% reporting receiving no, or very little CM education or training. Only 61.2% had knowledge of physical abuse as a main form of child maltreatment and 38.8% were able to identify corresponding symptoms of physical abuse. Sexual abuse as a main form of CM was mentioned by 26.5 and 2% cited its symptoms. While 87.7% of health care providers strongly agreed or agreed that they hold an important role in preventing CM, 51.1% also strongly disagreed or disagreed that they feel confident diagnosing and treating CM cases. In regards to follow-up, 14.3% strongly disagreed or disagreed that they know where to refer victims for further follow-up and an additional 14.3% did not know whether they agreed or disagreed. This study revealed knowledge gaps in emergency health care provider knowledge of the main forms of CM and their symptoms. The fact that a majority of health care providers in our sample did not receive information specific to CM in their medical education and training could explain this gap, as well as their unawareness of where to refer victims. Given that health care providers believe they play an important role in identifying and treating CM, future research should focus on raising physician awareness of CM and developing education and training materials grounded in cultural contexts to build response capacity in Mozambique and other LICs.

The talent process of successful academic women scientists at elite research universities in New York state

NASA Astrophysics Data System (ADS)

Kaenzig, Lisa M.

The importance of science in our society continues to increase, as the needs of the global culture and the problems of the world's growing populations affect resources internationally (DeLisi, 2008; Fischman, 2007; Park, 2008). The need for qualified and experienced scientists to solve complex problems is important to the future of the United States. Models of success for women in STEM disciplines are important to improve the recruitment and retention of women in academic science. This study serves as an examination of the facilitators and barriers---including external factors and internal characteristics---on the talent development process of successful women academic scientists. Since there are few studies relating specifically to the career experiences of successful women in academic science careers (Ceci & Williams, 2007; Wasserman, 2000; Xie & Shauman, 2003), a literature review was conducted that examined the (1) the gifted literature on women, including the eminence literature; (2) the higher education literature on women faculty and academic science, and (3) the literature related to the internal characteristics and external factors that influence the talent development process. The final section of the literature review includes a literature map (Creswell, 2009) outlining the major studies cited in this chapter. The conclusion, based on a critical analysis of the literature review, outlines the need for this study. The current study utilizes the framework of Gagne's differentiated talent development model for gifted individuals (Gagne, 1985, 1991) to examine the themes cited in multiple studies that influence the talent development process. Through a mixed-design methodology (Creswell, 2009) that incorporates quantitative and qualitative analysis using a survey and follow-up interviews with selected participants, this study seeks to explore the effects of internal characteristics, external influences, significant events, and experiences on the success of women scientists at elite research universities in New York. A criterion sample (n=94) was selected resulting in forty-one successful academic women scientists as the study participants, representing a response rate of 43.6%. Findings include the important roles of parents, teachers, mentors and collaborators on the talent development process of the participants. The perception of the study participants was that there were multiple facilitators to their talent development process, while few barriers were acknowledged. The most important barriers cited by participants were perceptions of institutional culture and sexism. Implications for practice in both gifted and higher education are suggested, based on the findings of the study. For gifted education, these suggestions include the need to provide parental education programs emphasizing the importance of intellectual engagement at home, providing dedicated time for science in primary education, and fostering science and mathematics opportunities, particularly for girls and young women. Stressing the importance of hard work, persistence and intelligent risk-taking are also important for encouraging girls in science. For higher education, the study provides models of success of academic women scientists, outlines the importance of mentors and collaborators, and emphasizes the critical role that institutions and departments play in facilitating or impeding women's career development as academics. The current study suggests several areas for further research to continue the exploration of the talent development influences on academic women scientists. Based on the findings of this study, recommended studies include examining the differences of generational cohorts; probing the roles of collaborators/mentor colleagues; exploring differences for women from various ethnic and racial backgrounds; replicating the current study with larger populations of women scientists; investigating the role of facilitative school environments; examining the patterns of influence of first generation successful academic women, and evaluating matched pairs of male and female successful academics.

2017-07-01

Physical activity and exercise have important health benefits for children and adolescents with CHD. The objective of this study was to survey the provision of advice and recommendations in United Kingdom paediatric CHD clinics. A three-page questionnaire was sent out to paediatric cardiac consultants in the United Kingdom, paediatric consultants with expertise in cardiology, and nursing staff (Paediatricians with Expertise in Cardiology Special Interest Group), as well as all members of the British Congenital Cardiovascular Association. The aim of this questionnaire was to determine the extent and scope of current information provision and to assess the importance that clinicians place on this advice. There were 68 responses in total, and the data showed that, of these, 24 (36%) clinicians had never provided paediatric CHD patients with written advice about exercise. Only 27 (39%) clinicians provided physical activity advice at every appointment. Lack of time during consultation (n=39, 56.9%), lack of training (n=38, 55.2%), and uncertainty about appropriate recommendations (n=38, 55.2%) were identified as the main factors preventing clinicians from providing patients with advice about physical activity. Although healthcare providers consider physical activity to be very important, the provision of clear, specific advice and recommendations is underutilised; therefore, more education and provision of resources to support the promotion of exercise need to be provided to clinicians and their support teams.

Empirical studies of the determinants of contests have been attempting to unravel the complexity of animal contest behaviour for decades. This complexity requires that experiments incorporate multiple determinants into studies to tease apart their relative effects. In this study we examined the complex contest behaviour of the tawny dragon (Ctenophorus decresii), a territorial agamid lizard, with the specific aim of defining the factors that determine contest outcome. We manipulated the relative size and residency status of lizards in contests to weight their importance in determining contest outcome. We found that size, residency and initiating a fight were all important in determining outcomes of fights. We also tested whether residency or size was important in predicting the status of lizard that initiated a fight. We found that residency was the most important factor in predicting fight initiation. We discuss the effects of size and residency status in context of previous studies on contests in tawny dragons and other animals. Our study provides manipulative behavioural data in support of the overriding effects of residency on initiation fights and winning them. PMID:23077558

"Do Users Do What They Think They Do?"- A Comparative Study of User Perceived and Actual Information Searching Behaviour in the National Electronic Library of Infection

In the last decade, the Internet has profoundly changed the delivery of healthcare. Medical websites for professionals and patients are playing an increasingly important role in providing the latest evidence-based knowledge for professionals, facilitating virtual patient support groups, and providing an invaluable information source for patients. Information seeking is the key user activity on the Internet. However, the discrepancy between what information is available and what the user is able to find has a profound effect on user satisfaction. The UK National electronic Library of Infection (NeLI, www.neli.org.uk) and its subsidiary projects provide a single-access portal for quality-appraised evidence in infectious diseases. We use this national portal, as test-bed for investigating our research questions. In this paper, we investigate actual and perceived user navigation behaviour that reveals important information about user perceptions and actions, in searching for information. Our results show: (i) all users were able to access information they were seeking; (ii) broadly, there is an agreement between "reported" behaviour (from questionnaires) and "observed" behaviour (from web logs), although some important differences were identified; (iii) both browsing and searching were equally used to answer specific questions and (iv) the preferred route for browsing for data on the NeLI website was to enter via the "Top Ten Topics" menu option. These findings provide important insights into how to improve user experience and satisfaction with health information websites.

The health of the European coastline is inextricably linked to the economy and culture of coastal nations but they are sensitive to climate change. As global temperatures increase, sea levels will rise and the forces experienced where land meets sea will become more destructive. Salt marshes, mudflats, beaches will be affected. These landscapes support a wide range of economically valuable animal and plant species, but also act as sites of carbon storage, nutrient recycling, and pollutant capture and amelioration. Their preservation is of utmost importance. Our programme: "A hierarchical approach to the examination of the relationship between biodiversity and ecosystem service flows across coastal margins" (CBESS) is designed to understand the landscape-scale links between the functions that these systems provide (ecosystem service flows) and the organisms that provide these services (biodiversity stocks) and moves beyond most previous studies, conducted at smaller scales. Our consortium of experts ranges from microbial ecologists, through environmental economists, to mathematical modellers, and organisations (RSPB, BTO, CEFAS, EA) with vested interest in the sustainable use of coastal wetlands. CBESS spans the landscape scale, investigating how biodiversity stocks provide ecosystem services (cf. National Ecosystem Assessment: Supporting services; Provisioning services; Regulating services; and Cultural services). CBESS combined a detailed study of two regional landscapes with a broad-scale UK-wide study to allow both specific and general conclusions to be drawn. The regional study compares two areas of great UK national importance: Morecambe Bay on the west coast and the Essex coastline on the east. We carried out biological and physical surveys at more than 600 stations combined with in situ measures of ecosystem funtction to clarify how biodiversity can provide these important ecosystem functions across scales. This information will be shared with those interested in using and managing coastal systems and we will propose practical methods and improved tools for the future analysis, management, and sustainability of coastal wetlands. The progamme and progress over the last 3 years will be described.

This study aims to describe the views of sexual health service providers on access issues for young people and consider them together with the views of young people themselves. A cross-sectional mixed-methods study design involving semi-structured interviews with health service providers and an electronic survey with young people. Four towns in rural and regional Queensland, Australia. A total of 32 service providers: 9 sexual health nurses, 8 general practitioners, 6 school-based youth health nurses, 5 sexual health educators, 2 Australian Aboriginal health workers and 2 youth workers. There were 391 young people who participated in the Young People's Survey. Themes generated from interviews with service providers and quantitative data from young people addressing access to sexual and reproductive health (SRH) services for rural and regional young people. Service providers frequently identified structural barriers, confidentiality and lack of awareness of SRH services as barriers for young people seeking SRH care. Young people also reported that structural factors such as transport, cost and service operating hours were important; however, they placed greater value on personal attributes of service providers, particularly welcoming and non-judgemental attitudes. Health service policy and training focused on attitudinal qualities of individual service providers may improve access to SRH services for young people. Selective staff recruitment and professional development are important to increase sensitivity to youth issues. Promotion of non-judgemental and confidential care may also improve access for youth. © 2015 National Rural Health Alliance Inc.

Emodin and Its Role in Chronic Diseases.

PubMed

Monisha, B Anu; Kumar, Niraj; Tiku, Ashu Bhan

Diseases, such as heart disease, stroke, cancer, respiratory diseases, and diabetes, are by far the leading cause of mortality in the world, representing 60 % of all deaths. Although substantial medical advances have been made and many therapeutic approaches proposed yet traditional medicine and medicinal plants find an important place in therapy. They have been providing invaluable solutions to the various health problems. Emodin (1,3,8-trihydroxy-6-methylanthraquinone) is a natural anthraquinone derivative found in various Chinese medicinal herbs. Traditionally, it has been used as an active constituent of many herbal laxatives. However, in the last few years, significant progress has been made in studying the biological effects of emodin at cellular and molecular levels and it is emerging as an important therapeutic agent. This review provides an overview of the modulatory effects of emodin in various diseases and cell signaling pathways, which may have important implications in its future clinical use.

On the meaning of sports: cross cultural observations of super stress.

The definition of sports medicine indicates the possible therapeutic and research importance of games in the work of social scientists and clinicians. A cross-cultural comparison of super stressful competitions provides one insight into the importance of games in human societies. Fourteen such comparisons are made between Indians in Mexico who run 250-mile foot races and Americans in Alaska who conduct 1049-mile dog sled races. It is concluded that sports can help understand how a society defines itself and regulates violence. Games may be an essential "human-specific' need which provide entertainment, retain survival skills, ameliorate existential anxiety and promote religious and/or secular socialization. In this study, humans seem willing, if not insistent, to deploy considerable resources of time and material to sustain competitions among their own species, as well as between and with other species. A "sports history' is important for all individuals.

Children account for an appreciable proportion of total imported malaria cases, yet few studies have quantified these cases, identified trends, or suggested evidence-based prevention strategies for this group of travelers. We therefore sought to identify numbers of cases and deaths, Plasmodium species, place of malaria acquisition, preventive measures used, and national origin of malaria in children. We analyzed retrospective data from Australia, Denmark, France, Germany, Italy, Japan, the Netherlands, Sweden, Switzerland, the United Kingdom, and the United States and data provided by the United Nations World Tourism Organization. During 1992–2002, >17,000 cases of imported malaria in children were reported in 11 countries where malaria is not endemic; most (>70%) had been acquired in Africa. Returning to country of origin to visit friends and relatives was a risk factor. Malaria prevention for children should be a responsibility of healthcare providers and should be subsidized for low-income travelers to high-risk areas. PMID:19193261

Paget Schroetter Syndrome: A case study of the chiropractor's role in recognizing and comanaging an important condition.

PubMed

Rowan, Tracy L; Kazemi, Mohsen

2012-12-01

To emphasize the importance for health care professionals to be knowledgeable of a relatively rare form of thoracic outlet syndrome, known as Paget Schroetter syndrome. The etiology, key signs and symptoms, and the importance of immediate referral are highlighted and an introduction to manual therapists' role within a multidisciplinary team is provided. Healthy athletes aged 15-30 are most commonly affected with 60-80% of patients reporting a history of repetitive or vigorous overhead activity prior to symptom onset. Manual therapists have a role in recognizing, referring, and providing symptomatic relief with soft tissue therapy, correcting abnormal biomechanics, manipulations, mobilizations, and a rehabilitative program, as seen in this case report. Early recognition and referral of Paget Schroetter syndrome are essential for optimal recovery. Manual therapists may prove to have a role in decreasing the need for surgical decompression and accelerating resumption of regular activities.

How to quantify conduits in wood?

Scholz, Alexander; Klepsch, Matthias; Karimi, Zohreh; Jansen, Steven

2013-01-01

Vessels and tracheids represent the most important xylem cells with respect to long distance water transport in plants. Wood anatomical studies frequently provide several quantitative details of these cells, such as vessel diameter, vessel density, vessel element length, and tracheid length, while important information on the three dimensional structure of the hydraulic network is not considered. This paper aims to provide an overview of various techniques, although there is no standard protocol to quantify conduits due to high anatomical variation and a wide range of techniques available. Despite recent progress in image analysis programs and automated methods for measuring cell dimensions, density, and spatial distribution, various characters remain time-consuming and tedious. Quantification of vessels and tracheids is not only important to better understand functional adaptations of tracheary elements to environment parameters, but will also be essential for linking wood anatomy with other fields such as wood development, xylem physiology, palaeobotany, and dendrochronology.

Workplace injuries and the take-up of Social Security disability benefits.

PubMed

O'Leary, Paul; Boden, Leslie I; Seabury, Seth A; Ozonoff, Al; Scherer, Ethan

2012-01-01

Workplace injuries and illnesses are an important cause of disability. State workers' compensation programs provide almost $60 billion per year in cash and medical-care benefits for those injuries and illnesses. Social Security Disability Insurance (DI) is the largest disability insurance program in the United States, with annual cash payments to disabled workers of $95 billion in 2008. Because injured workers may also receive DI benefits, it is important to understand how those two systems interact to provide benefits. This article uses matched state workers' compensation and Social Security data to study the relationship between workplace injuries and illnesses and DI benefit receipt. We find that having a lost-time injury substantially increases the probability of DI receipt, and, for people who become DI beneficiaries, those with injuries receive DI benefits at younger ages. This relationship remains robust even after we account for important personal and work characteristics.

Here, observations of relaxed, massive, and distant clusters can provide important tests of standard cosmological models, for example by using the gas mass fraction. To perform this test, the dynamical state of the cluster and its gas properties have to be investigated. X-ray analyses provide one of the best opportunities to access this information and to determine important properties such as temperature profiles, gas mass, and the total X-ray hydrostatic mass. For the last of these, weak gravitational lensing analyses are complementary independent probes that are essential in order to test whether X-ray masses could be biased.

End-of-life care requires knowledgeable and culturally sensitive clinicians to assist patients and families dealing with the difficult journey of death. The authors present important end-of-life considerations for health care providers dealing with culturally diversified patients. A case study approach is used illustrating two case vignettes derived from the practice of an intensive care setting of a tertiary teaching facility in a large urban area in Lebanon. In a multidisciplinary fashion, practices of end of life were explored and a protocol developed to guide health care providers. Special cultural values were identified such as importance of family involvement and religious beliefs. Implications for practice are described.

It is important to understand the perceptions and beliefs of family child care providers (FCCPs) regarding which factors influence children's physical activity (PA), screen-time (ST), and dietary behaviors in order to develop and implement appropriate obesity prevention interventions. The aim of this qualitative study was to explore the aforementioned perceptions and beliefs of FCCPs in Rhode Island. Four focus groups (n = 30) were held with FCCPs. Providers were female, Hispanic, and Spanish speaking. Providers were asked about different aspects of feeding, PA, and ST behaviors. Themes were coded using NVivo10 (QSR International Pty Ltd, Doncaster, Victoria, Australia). Content analysis was used to analyze final themes. Providers understood the importance of providing opportunities for healthy eating and PA for the children they cared for, but there was room for improvement, especially with regard to certain feeding and ST practices. Several barriers were evident, including the lack of physical infrastructure for PA, cultural beliefs and practices related to child feeding, and difficulties working with parents to provide consistent messages across environments. Given that FCCPs are aware of the importance of healthy eating and PA, there is a need to address the specific barriers they face, and operationalize some of their knowledge into practical everyday actions. This formative work will inform the development of a culturally relevant, multicomponent intervention for ethnically diverse FCCPs to improve the food and PA environments of their homes, which should, in turn, improve the dietary, PA, and ST behaviors of the 2- to 5-year-old children they care for.

Estimate variable importance for recurrent event outcomes with an application to identify hypoglycemia risk factors.

PubMed

Duan, Ran; Fu, Haoda

2015-08-30

Recurrent event data are an important data type for medical research. In particular, many safety endpoints are recurrent outcomes, such as hypoglycemic events. For such a situation, it is important to identify the factors causing these events and rank these factors by their importance. Traditional model selection methods are not able to provide variable importance in this context. Methods that are able to evaluate the variable importance, such as gradient boosting and random forest algorithms, cannot directly be applied to recurrent events data. In this paper, we propose a two-step method that enables us to evaluate the variable importance for recurrent events data. We evaluated the performance of our proposed method by simulations and applied it to a data set from a diabetes study. Copyright © 2015 John Wiley & Sons, Ltd.

This Delphi study provides consensus related to many aspects of acute diverticulitis and identifies other areas in need of research. To generate an international, expert-based, consensus statement to address controversies in the management of acute diverticulitis. This study was conducted using the Delphi technique from April 3 through October 21, 2014. A survey website was used and a panel of acute diverticulitis experts was formed via the snowball method. The top 5 acute diverticulitis experts in 5 international geographic regions were identified based on their number of publications related to acute diverticulitis. The Delphi study used 3 rounds of questions, after which the consensus statement was collated. A consensus statement related to the management of acute diverticulitis. Twenty items were selected for inclusion in the consensus statement following 3 rounds of questioning. A clear definition of uncomplicated and complicated diverticulitis is provided. In uncomplicated diverticulitis, consensus was reached regarding appropriate laboratory and radiological evaluation of patients as well as nonsurgical, surgical, and follow-up strategies. A number of important topics, including antibiotic treatment, failed to reach consensus. In addition, consensus was reached regarding many nonsurgical and surgical treatment strategies in complicated diverticulitis. Controversy continues internationally regarding the management of acute diverticulitis. This study demonstrates that there is more nonconsensus among experts than consensus regarding most issues, even in the same region. It also provides insight into the status quo regarding the treatment of acute diverticulitis and provides important direction for future research.

Refugees are one of the most vulnerable groups in Australian society, presenting high levels of exposure to traumatic events and consequently high levels of severe psychological distress. While there is a need for professional help, only a small percentage will receive appropriate care for their mental health concerns. This study aimed to determine cultural considerations required when providing mental health first aid to Iraqi refugees experiencing mental health problems or crises. Using a Delphi method, 16 experts were presented with statements about possible culturally-appropriate first aid actions via questionnaires and were encouraged to suggest additional actions not covered by the questionnaire content. Statements were accepted for inclusion in a guideline if they were endorsed by ≥90 % of panellists as 'Essential' or 'Important'. From a total of 65 statements, 38 were endorsed (17 for cultural awareness, 12 for cross-cultural communication, 7 for stigma associated with mental health problems, and 2 for barriers to seeking professional help). Experts were able to reach consensus about how to provide culturally-appropriate first aid for mental health problems to Iraqi refugees, demonstrating the suitability of this methodology in developing cultural considerations guidelines. This specific refugee study provided potentially valuable cultural knowledge required to better equip members of the Australian public on how to respond to and assist Iraqi refugees experiencing mental health problems or crises.

[Ethical considerations in genomic cohort study].

During the last decade, genomic cohort study has been developed in many countries by linking health data and genetic data in stored samples. Genomic cohort study is expected to find key genetic components that contribute to common diseases, thereby promising great advance in genome medicine. While many countries endeavor to build biobank systems, biobank-based genome research has raised important ethical concerns including genetic privacy, confidentiality, discrimination, and informed consent. Informed consent for biobank poses an important question: whether true informed consent is possible in population-based genomic cohort research where the nature of future studies is unforeseeable when consent is obtained. Due to the sensitive character of genetic information, protecting privacy and keeping confidentiality become important topics. To minimize ethical problems and achieve scientific goals to its maximum degree, each country strives to build population-based genomic cohort research project, by organizing public consultation, trying public and expert consensus in research, and providing safeguards to protect privacy and confidentiality.

2016-06-07

Providing clean water and sufficient affordable energy to all without compromising the environment is a key priority in the scientific community. Many recent studies have focused on carbon-based devices in the hope of addressing this grand challenge, justifying and motivating detailed studies of water in contact with carbonaceous materials. Such studies are becoming increasingly important because of the miniaturization of newly proposed devices, with ubiquitous nanopores, large surface-to-volume ratio, and many, perhaps most of the water molecules in contact with a carbon-based surface. In this brief review, we discuss some recent advances obtained via simulations and experiments in the development of carbon-based materials for applications in water desalination. We suggest possible ways forward, with particular emphasis on the synergistic combination of experiments and simulations, with simulations now sometimes offering sufficient accuracy to provide fundamental insights. We also point the interested reader to recent works that complement our short summary on the state of the art of this important and fascinating field.

Rosaceae Fruit Development, Ripening and Post-harvest: An Epigenetic Perspective

2017-01-01

Rosaceae is a family with an extraordinary spectrum of fruit types, including fleshy peach, apple, and strawberry that provide unique contributions to a healthy diet for consumers, and represent an excellent model for studying fruit patterning and development. In recent years, many efforts have been made to unravel regulatory mechanism underlying the hormonal, transcriptomic, proteomic and metabolomic changes occurring during Rosaceae fruit development. More recently, several studies on fleshy (tomato) and dry (Arabidopsis) fruit model have contributed to a better understanding of epigenetic mechanisms underlying important heritable crop traits, such as ripening and stress response. In this context and summing up the results obtained so far, this review aims to collect the available information on epigenetic mechanisms that may provide an additional level in gene transcription regulation, thus influencing and driving the entire Rosaceae fruit developmental process. The whole body of information suggests that Rosaceae fruit could become also a model for studying the epigenetic basis of economically important phenotypes, allowing for their more efficient exploitation in plant breeding.

2012-01-01

Optical mapping has become an increasingly important tool to study cardiac electrophysiology in the past 20 years. Multiple methods are used to process and analyze cardiac optical mapping data, and no consensus currently exists regarding the optimum methods. The specific methods chosen to process optical mapping data are important because inappropriate data processing can affect the content of the data and thus alter the conclusions of the studies. Details of the different steps in processing optical imaging data, including image segmentation, spatial filtering, temporal filtering, and baseline drift removal, are provided in this review. We also provide descriptions of the common analyses performed on data obtained from cardiac optical imaging, including activation mapping, action potential duration mapping, repolarization mapping, conduction velocity measurements, and optical action potential upstroke analysis. Optical mapping is often used to study complex arrhythmias, and we also discuss dominant frequency analysis and phase mapping techniques used for the analysis of cardiac fibrillation. PMID:22821993

Self-assembly of molecular systems is an important and general problem that intertwines physics, chemistry, biology, and material sciences. Through understanding of the physical principles of self-organization, it often becomes feasible to control the process and to obtain complex structures with tailored properties, for example, bacteria colonies of cells or nanodevices with desired properties. Theoretical studies and simulations provide an important tool for unraveling the principles of self-organization and, therefore, have recently gained an increasing interest. The present article features an extension of a popular code MBN EXPLORER (MesoBioNano Explorer) aiming to provide a universal approach to study self-assembly phenomena in biology and nanoscience. In particular, this extension involves a highly parallelized module of MBN EXPLORER that allows simulating stochastic processes using the kinetic Monte Carlo approach in a three-dimensional space. We describe the computational side of the developed code, discuss its efficiency, and apply it for studying an exemplary system. Copyright © 2014 Wiley Periodicals, Inc.

Containerless Processing in Reduced Gravity Using the TEMPUS Facility

1996-01-01

Containerless processing provides a high purity environment for the study of high-temperature, very reactive materials. It is an important method which provides access to the metastable state of an undercooled melt. In the absence of container walls, the nucleation rate is greatly reduced and undercooling up to (Tm-Tn)/Tm approx. 0.2 can be obtained, where Tm and Tn are the melting and nucleation temperatures, respectively. Electromagnetic levitation represents a method particularly well-suited for the study of metallic melts. The TEMPUS facility is a research instrument designed to perform electromagnetic levitation studies in reduced gravity. It provides temperatures up to 2600 C, levitation of several grams of material and access to the undercooled state for an extended period of time (up to hours).

Nature versus Nurture in Determining Athletic Ability.

2016-01-01

This overview provides a general discussion of the roles of nature and nurture in determining human athletic ability. On the nature (genetics) side, a review is provided with emphasis on the historical research and on several areas which are likely to be important for future research, including next-generation sequencing technologies. In addition, a number of well-designed training studies that could possibly reveal the biological mechanism ('cause') behind the association between gene variants and athletic ability are discussed. On the nurture (environment) side, we discuss common environmental variables including deliberate practice, family support, and the birthplace effect, which may be important in becoming an elite athlete. Developmental effects are difficult to disassociate with genetic effects, because the early life environment may have long-lasting effects in adulthood. With this in mind, the fetal programming hypothesis is also briefly reviewed, as fetal programming provides an excellent example of how the environment interacts with genetics. We conclude that the traditional argument of nature versus nurture is no longer relevant, as it has been clearly established that both are important factors in the road to becoming an elite athlete. With the availability of the next-generation genetics (sequencing) techniques, it is hoped that future studies will reveal the relevant genes influencing performance, as well as the interaction between those genes and environmental (nurture) factors. © 2016 S.

Insects are nutritious and suitable for human consumption. In this article an overview of research on consumer acceptance of entomophagy is given. This study furthermore provides insight into which factors are effective to influence consumer acceptance of entomophagy among Dutch and Australian participants. Based on the findings of this study, information about entomophagy and providing the participants with the opportunity to try insect food, both seem to be equally important when trying to positively influence their attitude toward entomophagy. The outcomes of this study show that "educating" consumers about entomophagy should be practiced in its broadest sense.

Greed is an important motive: it is seen as both productive (a source of ambition; the motor of the economy) and destructive (undermining social relationships; the cause of the late 2000s financial crisis). However, relatively little is known about what greed is and does. This article reports on 5 studies that develop and test the 7-item Dispositional Greed Scale (DGS). Study 1 (including 4 separate samples from 2 different countries, total N = 6092) provides evidence for the construct and discriminant validity of the DGS in terms of positive correlations with maximization, self-interest, envy, materialism, and impulsiveness, and negative correlations with self-control and life satisfaction. Study 2 (N = 290) presents further evidence for discriminant validity, finding that the DGS predicts greedy behavioral tendencies over and above materialism. Furthermore, the DGS predicts economic behavior: greedy people allocate more money to themselves in dictator games (Study 3, N = 300) and ultimatum games (Study 4, N = 603), and take more in a resource dilemma (Study 5, N = 305). These findings shed light on what greed is and does, how people differ in greed, and how greed can be measured. In addition, they show the importance of greed in economic behavior and provide directions for future studies. (c) 2015 APA, all rights reserved).

Osteoporosis therapies: evidence from health-care databases and observational population studies.

PubMed

Silverman, Stuart L

2010-11-01

Osteoporosis is a well-recognized disease with severe consequences if left untreated. Randomized controlled trials are the most rigorous method for determining the efficacy and safety of therapies. Nevertheless, randomized controlled trials underrepresent the real-world patient population and are costly in both time and money. Modern technology has enabled researchers to use information gathered from large health-care or medical-claims databases to assess the practical utilization of available therapies in appropriate patients. Observational database studies lack randomization but, if carefully designed and successfully completed, can provide valuable information that complements results obtained from randomized controlled trials and extends our knowledge to real-world clinical patients. Randomized controlled trials comparing fracture outcomes among osteoporosis therapies are difficult to perform. In this regard, large observational database studies could be useful in identifying clinically important differences among therapeutic options. Database studies can also provide important information with regard to osteoporosis prevalence, health economics, and compliance and persistence with treatment. This article describes the strengths and limitations of both randomized controlled trials and observational database studies, discusses considerations for observational study design, and reviews a wealth of information generated by database studies in the field of osteoporosis.

Epigenetics is emerging as an important field in cancer epidemiology that promises to provide insights into gene regulation and facilitate cancer control throughout the cancer care continuum. Increasingly, investigators are incorporating epigenetic analysis into the studies of etiology and outcomes. To understand current progress and trends in the inclusion of epigenetics in cancer epidemiology, we evaluated the published literature and the National Cancer Institute (NCI) supported research grant awards in this field to identify trends in epigenetics research. We present a summary of the epidemiological studies in NCI’s grant portfolio (from January 2005 through December 2012) and in the scientific literature published during the same period, irrespective of support from NCI. Blood cells and tumor tissue were the most commonly used biospecimens in these studies, although buccal cells, cervical cells, sputum, and stool samples also were used. DNA methylation profiling was the focus of the majority of studies, but several studies also measured microRNA profiles. We illustrate here the current status of epidemiologic studies that are evaluating epigenetic changes in large populations. The incorporation of epigenomic assessments in cancer epidemiology studies has and is likely to continue to provide important insights into the field of cancer research. PMID:24326628

Too cold may not be so cool: spontaneous hypothermia as a marker of poor outcome after cardiac arrest.

Wörner, Jakobea; Oddo, Mauro

2010-01-01

In a recent issue of Critical Care, den Hartog and colleagues show an association between spontaneous hypothermia, defined by an admission body temperature < 35°C, and poor outcome in patients with coma after cardiac arrest (CA) treated with therapeutic hypothermia (TH). Given that TH alters neurological prognostication, studies aiming to identify early markers of injury severity and outcome are welcome, since they may contribute overall to optimize the management of comatose CA patients. This study provides an important message to clinicians involved in post-resuscitation care and raises important questions that need to be taken into account in future studies.

Converting the findings from addictions studies into information actionable by (non-research) treatment programs is important to improving program outcomes. This paper describes the translation of the findings of studies on Patient-Services matching, prediction of patient response to treatment (Expected Treatment Response) and prediction of dropout to provide evidence-based decision support in routine treatment. The findings of the studies and their application to the development of an outcomes management system are described. Implementation issues in a network of addictions treatment programs are discussed. The work illustrates how outcomes management systems can play an important role in translating research into practice. PMID:21324606

The principle purpose of this symposium is to provide the EGRET (Energetic Gamma-Ray Experiment Telescope) scientists with an opportunity to study and improve their understanding of high energy gamma ray astronomy. The Symposium began with the galactic diffusion radiation both because of its importance in studying galactic cosmic rays, galactic structure, and dynamic balance, and because an understanding of its characteristics is important in the study of galactic sources. The galactic objects to be reviewed included pulsars, bursts, solar flares, and other galactic sources of several types. The symposium papers then proceeded outward from the Milky Way to normal galaxies, active galaxies, and the extragalactic diffuse radiation.

Structural atlas of dynein motors at atomic resolution.

Dynein motors are biologically important bio-nanomachines, and many atomic resolution structures of cytoplasmic dynein components from different organisms have been analyzed by X-ray crystallography, cryo-EM, and NMR spectroscopy. This review provides a historical perspective of structural studies of cytoplasmic and axonemal dynein including accessory proteins. We describe representative structural studies of every component of dynein and summarize them as a structural atlas that classifies the cytoplasmic and axonemal dyneins. Based on our review of all dynein structures in the Protein Data Bank, we raise two important points for understanding the two types of dynein motor and discuss the potential prospects of future structural studies.

The cognitive consequences of envy: attention, memory, and self-regulatory depletion.

PubMed

Hill, Sarah E; DelPriore, Danielle J; Vaughan, Phillip W

2011-10-01

In a series of 4 experiments, we provide evidence that--in addition to having an affective component--envy may also have important consequences for cognitive processing. Our first experiment (N = 69) demonstrated that individuals primed with envy better attended to and more accurately recalled information about fictitious peers than did a control group. Studies 2 (N = 187) and 3 (N = 65) conceptually replicated these results, demonstrating that envy elicited by targets predicts attention and later memory for information about them. We demonstrate that these effects cannot be accounted for by admiration or changes in negative affect or arousal elicited by the targets. Study 4 (N = 152) provides evidence that greater memory for envied--but not neutral--targets leads to diminished perseverance on a difficult anagram task. Findings demonstrate that envy may play an important role in attention and memory systems and deplete limited self-regulatory resources available for acts of volition. 2011 APA, all rights reserved

2016-12-01

Understanding the passive or nonpassive behavior of the neuromuscular system is important to design and control robots that physically interact with humans, since it provides quantitative information to secure coupled stability while maximizing performance. This has become more important than ever apace with the increasing demand for robotic technologies in neurorehabilitation. This paper presents a quantitative characterization of passive and nonpassive behavior of the ankle of young healthy subjects, which provides a baseline for future studies in persons with neurological impairments and information for future developments of rehabilitation robots, such as exoskeletal devices and powered prostheses. Measurements using a wearable ankle robot actuating 2 degrees-of-freedom of the ankle combined with curl analysis and passivity analysis enabled characterization of both quasi-static and steady-state dynamic behavior of the ankle, unavailable from single DOF studies. Despite active neuromuscular control over a wide range of muscle activation, in young healthy subjects passive or dissipative ankle behavior predominated.

As our driving population continues to age, it is becoming increasingly important to find a small set of easily administered fitness metrics that can meaningfully and reliably identify at-risk seniors requiring more in-depth evaluation of their driving skills and weaknesses. Sixty driver assessment metrics related to fitness-to-drive were examined for 20 seniors who were followed for a year using the naturalistic driving paradigm. Principal component analysis and negative binomial regression modeling approaches were used to develop parsimonious models relating the most highly predictive of the driver assessment metrics to the safety-related outcomes observed in the naturalistic driving data. This study provides important confirmation using naturalistic driving methods of the relationship between contrast sensitivity and crash-related events. The results of this study provide crucial information on the continuing journey to identify metrics and protocols that could be applied to determine seniors' fitness to drive.

Blocking NF-κB: an inflammatory issue.

PubMed

Rahman, Arshad; Fazal, Fabeha

2011-11-01

The nuclear factor (NF)-κB is considered the master regulator of inflammatory responses. Studies in mouse models have established this transcription factor as an important mediator of many inflammatory disease states, including pulmonary diseases such as acute lung injury and acute respiratory distress syndrome. Endothelial cells provide the first barrier for leukocytes migrating to the inflamed sites and hence offer an attractive cellular context for targeting NF-κB for treatment of these diseases. However, recent studies showing that NF-κB also plays an important role in resolution phase of inflammation and in tissue repair and homeostasis have challenged the view of therapeutic inhibition of NF-κB. This article reviews the regulation of NF-κB in the context of endothelial cell signaling and provides a perspective on why "dampening" rather than "abolishing" NF-κB activation may be a safe and effective treatment strategy for inflammation-associated pulmonary and other inflammatory diseases.

Background The promise of microbicides as an HIV prevention method will not be realized if not supported by health care providers. They are the primary source of sexual health information for potential users, in both the public and private health sectors. Therefore, the aim of this study was to determine perceptions of vaginal microbicides as a potential HIV prevention method among health care providers in Durban and Hlabisa, South Africa, using a combination of quantitative and qualitative methods. Results During 2004, semi structured interviews with 149 health care providers were conducted. Fifty seven percent of hospital managers, 40% of pharmacists and 35% of nurses possessed some basic knowledge of microbicides, such as the product being used intra-vaginally before sex to prevent HIV infection. The majority of them were positive about microbicides and were willing to counsel users regarding potential use. Providers from both public and private sectors felt that an effective microbicide should be available to all people, regardless of HIV status. Providers felt that the product should be accessed over-the-counter in pharmacies and in retail stores. They also felt a need for potential microbicides to be available free of charge, and packaged with clear instructions. The media was seen by health care providers as being an effective strategy for promoting microbicides. Conclusion Overall, health care providers were very positive about the possible introduction of an effective microbicide for HIV prevention. The findings generated by this study illustrated the need for training health care providers prior to making the product accessible, as well as the importance of addressing the potential barriers to use of the product by women. These are important concerns in the health care community, and this study also served to educate them for the day when research becomes reality. PMID:17359528

Introduction Older adults with chronic pain who seek treatment often are in a health care environment that emphasizes patient-directed care, a change from the patriarchal model of care to which many older adults are accustomed. Objective To explore the experiences of older adults seeking treatment for chronic pain, with respect to patient-directed care and the patient–provider relationship. Design In-depth interviews with 15 Caucasian older adults with chronic pain who had been evaluated at a university-based pain clinic. All interviews were audiotaped and the transcripts were analyzed using a grounded theory based approach. Results Older adults with chronic pain vary in their willingness to be involved in their treatment decisions. Many frequently participate in decisions about their pain treatment by asking for or refusing specific treatments, demanding quality care, or operating outside of the patient–provider relationship to manage pain on their own. However, others prefer to let their provider make the decisions. In either case, having a mutually respectful patient–provider relationship is important to this population. Specifically, participants described the importance of “being heard” and “being understood” by providers. Conclusions As some providers switch from a patriarchal model of care toward a model of care that emphasizes patient activation and patient-centeredness, the development and cultivation of valued patient–provider relationships may change. While it is important to encourage patient involvement in treatment decisions, high-quality, patient-centered care for older adults with chronic pain should include efforts to strengthen the patient–provider relationship by attending to differences in patients’ willingness to engage in patient-directed care and emphasizing shared decision-making.

Recognizing the importance of health-promoting relationships in engaging people who are experiencing homelessness in care, most research on health clinics for homeless persons has involved some recognition of client-provider relationships. However, what has been lacking is the inclusion of a critical analysis of the policy context in which relationships are enacted. In this paper, we question how client-provider relationships are enacted within the culture of community care with people who are experiencing homelessness and how clinic-level and broader social and health policies shape relationships in this context. We explore these questions within a critical theoretical perspective utilizing a critical ethnographic methodology. Data were collected using multiple methods of document review, participant observation, in-depth interviews and focus groups. The participants include both clients at a community health clinic, and all clinic service providers. We explore how clients and providers characterized each other as 'good' or 'bad'. For providers, this served as a means by which they policed behaviours and enforced social norms. The means by which both providers' and clients' negotiated relationships are explored, but this is couched within both local and system-level policies. This study highlights the importance of healthcare providers and clients being involved in broader policy and systemic change. © 2013 John Wiley & Sons Ltd.

Abstract Background. Cervical cancer is the second most commonly diagnosed cancer in females and is a leading cause of cancer‐related mortality in Kenya; limited cervical cancer screening services may be a factor. Few studies have examined men's and women's perceptions on environmental and psychosocial barriers and benefits related to screening. Materials and Methods. In 2014, 60 women aged 25–49 years and 40 male partners participated in 10 focus groups (6 female and 4 male), in both rural and urban settings (Nairobi and Nyanza, Kenya), to explore perceptions about barriers to and benefits of cervical cancer screening. Focus groups were segmented by sex, language, geographic location, and screening status. Data were transcribed, translated into English, and analyzed by using qualitative software. Results. Participants identified screening as beneficial for initiating provider discussions about cancer but did not report it as a beneficial method for detecting precancers. Perceived screening barriers included access (transportation, cost), spousal approval, stigma, embarrassment during screening, concerns about speculum use causing infertility, fear of residual effects of test results, lack of knowledge, and religious or cultural beliefs. All participants reported concerns with having a male doctor perform screening tests; however, men uniquely reported the young age of a doctor as a barrier. Conclusion. Identifying perceived barriers and benefits among people in low‐ and middle‐income countries is important to successfully implementing emerging screening programs. The novel findings on barriers and benefits from this study can inform the development of targeted community outreach activities, communication strategies, and educational messages for patients, families, and providers. Implications for Practice. This article provides important information for stakeholders in clinical practice and research when assessing knowledge, beliefs, and acceptability of cervical cancer screening and treatment services in low‐ and middle‐resourced countries. Formative research findings provide information that could be used in the development of health interventions, community education messages, and materials. Additionally, this study illuminates the importance of understanding psychosocial barriers and facilitators to cervical cancer screening, community education, and reduction of stigma as important methods of improving prevention programs and increasing rates of screening among women.

An Enhanced Understanding of Therapeutic Communities Worldwide.

Tiburcio, Nelson Jose; Kressel, David

Therapeutic communities posit favorable treatment outcomes by relying on the community as the healing agent (Deleon 2000). Active treatment participation and treatment tenure are two domains that are positive predictors of positive treatment outcomes over time. Some of the more important domains that remain to be thoroughly investigated in international research on therapeutic community (TC) treatment outcome studies are the underlying effects of culture on the treatment process. Cultural components play a significant role, as also reported by various TC participants over the years (such as the effects of health literacy on sustaining abstinence from drug use over the long term, Tiburcio 2008). In recent years, health literacy has taken on a significant role in order for individuals to readily understand their needs (Schillinger et al 2002; Jorm et al 1997); or as pertains to feeling shamed in the process (Parikh et al 1996). As these and other studies suggest, the cultural competence of the providers is equally important. To our knowledge the " International TC Study " and findings presented herein constitute one of only a few studies that have conducted investigations comparing therapeutic community treatment modifications internationally, from the perspective of the participants themselves and which consider cultural components of this process. One key advantage of the resulting Qualitative datasets and analyses is that it not only includes residents' perspectives, and staff experiential elements, but importantly, incorporates staff debriefings about their respective interactions at each of the international treatment modalities, presenting well rounded depictions of each of these milieus. To that end, the data examined here presents an enhanced portrait of the provider-patient treatment dynamic, and lends voice to the various aspects of treatment participation in light of these cultural issues, and from the perspective of providers, as well as the participants.

The mouse has become an increasingly important animal model for visual system studies, but few studies have investigated local functional circuit organization of mouse visual cortex. Here we used our newly developed mapping technique combining laser scanning photostimulation (LSPS) with fast voltage-sensitive dye (VSD) imaging to examine the spatial organization and temporal dynamics of laminar circuit responses in living slice preparations of mouse primary visual cortex (V1). During experiments, LSPS using caged glutamate provided spatially restricted neuronal activation in a specific cortical layer, and evoked responses from the stimulated layer to its functionally connected regions were detected by VSD imaging. In this study, we first provided a detailed analysis of spatiotemporal activation patterns at specific V1 laminar locations and measured local circuit connectivity. Then we examined the role of cortical inhibition in the propagation of evoked cortical responses by comparing circuit activity patterns in control and in the presence of GABAa receptor antagonists. We found that GABAergic inhibition was critical in restricting layer-specific excitatory activity spread and maintaining topographical projections. In addition, we investigated how AMPA and NMDA receptors influenced cortical responses and found that blocking AMPA receptors abolished interlaminar functional projections, and the NMDA receptor activity was important in controlling visual cortical circuit excitability and modulating activity propagation. The NMDA receptor antagonist reduced neuronal population activity in time-dependent and laminar-specific manners. Finally, we used the quantitative information derived from the mapping experiments and presented computational modeling analysis of V1 circuit organization. Taken together, the present study has provided important new information about mouse V1 circuit organization and response modulation. PMID:23060751

We describe the importance of interprofessional care in modern critical care medicine. This review highlights the essential roles played by specific members of the interprofessional care team, including patients and family members, and discusses quality improvement initiatives that require interprofessional collaboration for success. Studies were identified through MEDLINE search using a variety of search phrases related to interprofessional care, critical care provider types, and quality improvement initiatives. Additional articles were identified through a review of the reference lists of identified articles. Original articles, review articles, and systematic reviews were considered. Manuscripts were selected for inclusion based on expert opinion of well-designed or key studies and review articles. "Interprofessional care" refers to care provided by a team of healthcare professionals with overlapping expertise and an appreciation for the unique contribution of other team members as partners in achieving a common goal. A robust body of data supports improvement in patient-level outcomes when care is provided by an interprofessional team. Critical care nurses, advanced practice providers, pharmacists, respiratory care practitioners, rehabilitation specialists, dieticians, social workers, case managers, spiritual care providers, intensivists, and nonintensivist physicians each provide unique expertise and perspectives to patient care, and therefore play an important role in a team that must address the diverse needs of patients and families in the ICU. Engaging patients and families as partners in their healthcare is also critical. Many important ICU quality improvement initiatives require an interprofessional approach, including Awakening and Breathing Coordination, Delirium, Early Exercise/Mobility, and Family Empowerment bundle implementation, interprofessional rounding practices, unit-based quality improvement initiatives, Patient and Family Advisory Councils, end-of-life care, coordinated sedation awakening and spontaneous breathing trials, intrahospital transport, and transitions of care. A robust body of evidence supports an interprofessional approach as a key component in the provision of high-quality critical care to patients of increasing complexity and with increasingly diverse needs.

In the last decade, there have been reports on the prevalence of glaucoma from the Vellore Eye Survey, Andhra Pradesh Eye Diseases Survey, Aravind Comprehensive Eye Survey, Chennai Glaucoma Study and West Bengal Glaucoma Study. Population-based studies provide important information regarding the prevalence and risk factors for glaucoma. They also highlight regional differences in the prevalence of various types of glaucoma. It is possible to gather important insights regarding the number of persons affected with glaucoma and the proportion with undiagnosed disease. We reviewed the different population-based studies from India and compare their findings. The lacunae in ophthalmic care that can be inferred from these studies are identified and possible reasons and solutions are discussed. We also discuss the clinical relevance of the various findings, and how it reflects on clinical practice in the country. Since India has a significantly high disease burden, we examine the possibility of population-based screening for disease in the Indian context. PMID:21150021

Despite an increasing literature on professional nurses' job satisfaction, job satisfaction by nonprofessional nursing care providers and, in particular, in residential long-term care facilities, is sparsely described. The purpose of this study was to systematically review the evidence on which factors (individual and organizational) are associated with job satisfaction among care aides, nurse aides, and nursing assistants, who provide the majority of direct resident care, in residential long-term care facilities. Nine online databases were searched. Two authors independently screened, and extracted data and assessed the included publications for methodological quality. Decision rules were developed a priori to draw conclusions on which factors are important to care aide job satisfaction. Forty-two publications were included. Individual factors found to be important were empowerment and autonomy. Six additional individual factors were found to be not important: age, ethnicity, gender, education level, attending specialized training, and years of experience. Organizational factors found to be important were facility resources and workload. Two additional factors were found to be not important: satisfaction with salary/benefits and job performance. Factors important to care aide job satisfaction differ from those reported among hospital nurses, supporting the need for different strategies to improve care aide job satisfaction in residential long-term care.

Landscape connectivity is considered as an extraordinarily important factor affecting various ecological processes. The least cost path (LCP) on the basis of minimum cumulative resis-tance model (MCRM) may provide a more efficient approach to identify functional connectivity in heterogeneous landscapes, and is already adopted by the research of landscape functional connecti-vity assessment and ecological corridor simulation. Connectivity model on circuit theory (CMCT) replaced the edges in the graph theory with resistors, cost distance with resistance distance to measure the functional connectivity in heterogeneous landscapes. By means of Linkage Mapper tool and Circuitscape software, the simulated landscape generated from SIMMAP 2.0 software was viewed as the study object in this article, aimed at exploring how to integrate MCRM with CMCT to identify ecological corridors and relative importance of landscape factors. The results showed that two models had their individual advantages and mutual complement. MCRM could effectively identify least cost corridors among habitats. CMCT could effectively identify important landscape factor and pinch point, which had important influence on landscape connectivity. We also found that the position of pinch point was not affected by corridor width, which had obvious advantage in the research of identifying the importance of corridors. The integrated method could provide certain scientific basis for regional ecological protection planning and ecological corridor design.

Background Numerous studies have demonstrated an association between characteristics of the school environment and the likelihood of school violence. However, little is known about the relative importance of various characteristics of the school environment or their differential impact on multiple violence outcomes. Methods Primarily African-American students (n=27) from Baltimore City high schools participated in concept mapping sessions, which produced interpretable maps of the school environment's contribution to school violence. Participants generated statements about their school environment's influence on school violence and with the assistance of quantitative methods grouped these statements according to their similarity. Participants provided information about the importance of each of these statements for the initiation, cessation, and severity of the violence that occurs at school. Results More than half of the 132 statements generated by students were rated as school environment characteristics highly important for the initiation, cessation, and/or severity of school violence. Participants identified students' own actions, expectations for disruptive behavior, and the environment outside the school as characteristics most important for the initiation and increased severity of violence that occurs in school. Participants had a more difficult time identifying school environment characteristics important for the cessation of school violence. Conclusion This study provides support from students for the role of the school environment in school violence prevention, particularly in preventing the initiation and reducing the severity of school violence. Schools can utilize the information presented in this paper to begin discussions with students and staff about prioritizing school environment changes to reduce school violence. PMID:21592128

By observation of role models, and participation in activities, students develop their attitudes, values and professional competencies. Literature suggests that clinical skills and knowledge, personality, and teaching skills are three main areas that students consider central to the identification of positive role models. The aim of this study was to explore junior medical students' opinions of the ideal attributes of a good role model in clinical tutors. The study was conducted with one cohort (n = 301) of students who had completed year 1 of the medical programme in 2013. All students were asked to complete a questionnaire regarding the ideal attributes of a good role model in a clinical tutor. The questionnaire consisted of seven closed items and one open-ended question. The response rate to the questionnaire was 265/301 (88%). Although students found all three key areas important in a good role model, students emphasised the importance of excellence in teaching skills. Specifically, students see good role models as being able to provide a constructive learning environment, a good understanding of the curriculum and an ability to cater to the learning needs of all students. Students see good role models as being able to provide a constructive learning environment While acknowledging the importance of a patient-centred approach, as well as clinical knowledge and skills, our findings reinforce the importance of the actual teaching abilities of role models within medical education. © 2015 John Wiley & Sons Ltd.

Reactions on certain proton-rich, radioactive nuclei have been shown to have a significant influence on X-ray bursts. We provide an overview of two recent measurements of important X-ray burst reactions using in-flight radioactive ion beams from the RESOLUT facility at the J. D. Fox Superconducting Accelerator Laboratory at Florida State University. The 17F(d,n)18Ne reaction was measured, and Asymptotic Normalization Coefficients were extracted for bound states in 18Ne that determine the direct-capture cross section dominating the 17F(p,γ)18Ne reaction rate for T≲ 0.45 GK. Unbound resonant states were also studied, and the single-particle strength for the 4.523-MeV (3+) state was found to be consistent with previous results. The 19Ne(d,n)20Na proton transfer reaction was used to study resonances in the 19Ne(p,γ)20Na reaction. The most important 2.65-MeV state in 20Na was observed to decay by proton emission to both the ground and first-excited states in 19Ne, providing strong evidence for a 3+ spin assignment and indicating that proton capture on the thermally-populated first-excited state in 19Ne is an important contributor to the 19Ne(p,γ)20Na reaction rate.

While mental associations between a brand and its marketing elements are an important part of brand equity, previous research has yet to provide a sound methodology to measure the strength of these links. The following studies present the development and validation of an implicit measure to assess the strength of mental representations of brand elements in the mind of the consumer. The measure described in this paper, which we call the Brand Discrimination task, requires participants to identify whether images of brand elements (e.g. color, logo, packaging) belong to a target brand or not. Signal detection theory (SDT) is used to calculate a Brand Discrimination index which gives a measure of overall recognition accuracy for a brand’s elements in the context of its competitors. A series of five studies shows that the Brand Discrimination task can discriminate between strong and weak brands, increases when mental representations of brands are experimentally strengthened, is relatively stable across time, and can predict brand choice, independently and while controlling for other explicit and implicit brand evaluation measures. Together, these studies provide unique evidence for the importance of mental brand representations in marketing and consumer behavior, along with a research methodology to measure this important consumer-based brand attribute.

Objective To examine the importance of cardiorespiratory conditioning after traumatic brain injury (TBI) and provide recommendations for patients recovering from TBI. Method Review of literature assessing the effectiveness of endurance training programs. Main outcomes and results A sedentary lifestyle and lack of endurance are common characteristics of individuals with TBI who have a reduction in peak aerobic capacity of 25-30% compared to healthy sedentary persons. Increased physical activity and exercise training improves cardiorespiratory fitness in many populations with physical and cognitive impairments. Therefore, increasing the endurance and cardiorespiratory fitness of persons with TBI would seem to have important health implications. However, review of the TBI literature reveals that there have been few well-designed, well-controlled studies of physiologic and psychological adaptations of fitness training. Also lacking are long-term follow-up studies of persons with TBI. Conclusions Assessing endurance capacity and cardiorespiratory fitness early in the TBI rehabilitation process merits consideration as a standard of care by professional rehabilitation societies. Also, providing effective, safe and accessible training modalities would seem to be an important consideration for persons with TBI, given the mobility impairments many possess. Long-term follow-up studies are needed to assess the effectiveness of cardiorespiratory training programs on overall morbidity and mortality. PMID:20473091

Ecological study of peat landforms in Canada and Alaska

Over 20 percent of the land surface of Canada and Alaska is covered by peatlands, which may be defined as any waterlogged ecosystem with a minimum thickness of 20 cm of organic matter in the soil. Past investigations have demonstrated the value of aerial photographs in identifying the major vegetation types and analyzing the biotic and hydrogeologic processes that control the development of these peatlands. In the present study, LANDSAT TM imagery was used in conjunction with field studies to determine the utility of this satellite sensor for detecting these important processes. Although the vegetation landforms within these major peat basins are visible on aerial photographs, LANDSAT TM imagery provides essential new evidence for their analysis. Spectral data from the LANDSAT TM system provides: (1) synoptic views of the patterns across large portions of these peat basins, indicating important physiographic controls on peatland development, (2) more sensitive detection of the major vegetation types, allowing rapid quantitative estimates to be made of their distribution and aerial extent, (3) discrimination of bog areas with potentially rapid or slow rates of peat accumulation, (4) identification of discharge zones for groundwater, which apparently represents the most important source of alkalinity in these peat basins, and (5) detection of flow patterns in water tracks that appear nearly uniform on standard aerial photographs.

Protecting the environment and enhancing food security are among the world's Sustainable Development Goals and greatest challenges. International food trade is an important mechanism to enhance food security worldwide. Nonetheless, it is widely concluded that in international food trade importing countries gain environmental benefits, while exporting countries suffer environmental problems by using land and other resources to produce food for exports. Our study shows that international food trade can also lead to environmental pollution in importing countries. At the global level, our metaanalysis indicates that there was increased nitrogen (N) pollution after much farmland for domestically cultivated N-fixing soybeans in importing countries was converted to grow high N-demanding crops (wheat, corn, rice, and vegetables). The findings were further verified by an intensive study at the regional level in China, the largest soybean-importing country, where the conversion of soybean lands to corn fields and rice paddies has also led to N pollution. Our study provides a sharp contrast to the conventional wisdom that only exports contribute substantially to environmental woes. Our results suggest the need to evaluate environmental consequences of international trade of all other major goods and products in all importing countries, which have significant implications for fundamental rethinking in global policy-making and debates on environmental responsibilities among consumers, producers, and traders across the world.

Cultural diversity is becoming increasingly more important in the workplace. This is particularly true in health care organizations facing demographic shifts in the patients served and their families. This study serves to aid the development of intercultural communication training programs for health care providers by examining how cultural sensitivity and effective intercultural communication, besides helping patients, personally benefit health care providers by reducing their stress. Effective intercultural communication and cultural sensitivity were found to be related. Health care providers' levels of intercultural anxiety also were found to correlate with effective intercultural communication.

In this qualitative study, 29 HIV-positive, Chinese patients reported highly favorable impressions of their healthcare providers, who were seen as providing important medical-related, financial, and emotional support. Generally, the patient-provider relationship positively impacted the participants and their ability to maintain their health and was especially critical when patients were isolated from familial sources of support due to intense AIDS stigma. Often family members were informed of an HIV diagnosis before the patient, revealing tensions between Confucian principles of collectivism and familial authority and increasingly prevalent Western ideals of individual autonomy and the privileged status of personal health information.

Although the vaccination coverage in most high income countries is high, variations in coverage rates on the national level among different ethnic backgrounds are reported. A qualitative study was performed to explore factors that influence decision-making among parents with different ethnic backgrounds in the Netherlands. Six focus groups were conducted with 33 mothers of Moroccan, Turkish and other ethnic backgrounds with at least one child aged 0-4 years. Data were analysed using thematic analysis. Parents had a positive attitude towards childhood vaccination and a high confidence in the advices of Child Vaccine Providers (CVPs). Vaccinating their children was perceived as self-evident and important. Parents do perceive a language barrier in understanding the provided NIP-information, and they had a need for more NIP- information, particularly about the targeted diseases. Another barrier parents perceived was the distance to the Child Welfare Center (CWC), especially when the weather was bad and when they had no access to a car. More information about targeted diseases and complete information regarding benefits and drawbacks of the NIP should be provided to the parents. To fulfill parents' information needs, NIP information meetings can be organized at CWCs in different languages. Providing NIP information material in Turkish, Arabic and Berber language with easy access is also recommended. Providing information tailored to these parents' needs is important to sustain high vaccination participation, and to ensure acceptance of future vaccinations.

Latinos living with HIV residing in the US-Mexico border region frequently seek care on both sides of the border. Given this fact, a border health perspective to understanding barriers to care is imperative to improve patient health outcomes. This qualitative study describes and compares experiences and perceptions of Mexican and US HIV care providers regarding barriers to HIV care access for Latino patients living in the US-Mexico border region. In 2010, we conducted in-depth qualitative interviews with HIV care providers in Tijuana (n = 10) and San Diego (n = 9). We identified important similarities and differences between Mexican and US healthcare provider perspectives on HIV care access and barriers to service utilisation. Similarities included the fact that HIV-positive Latino patients struggle with access to ART medication, mental health illness, substance abuse and HIV-related stigma. Differences included Mexican provider perceptions of medication shortages and US providers feeling that insurance gaps influenced medication access. Differences and similarities have important implications for cross-border efforts to coordinate health services for patients who seek care in both countries. PMID:24592920

Many emerging adults (18-25 year olds) report unmet health needs and disproportionately experience problems such as sexually transmitted infections. This study was conducted to examine college students' perceptions of health care providers, specifically in the context of accessing sexual health resources. Students (N = 52) were recruited from five diverse colleges in one state to participate in a one-to-one interview that involved walking and virtually exploring resources on and near campus. Interviews were conducted from May to November 2010. Open-ended one-to-one interview questions. Inductive qualitative analysis yielded six themes summarizing students' perceptions of provider characteristics, health care resources, the role of their peers, and students' suggestions for strengthening health care services. Importantly, students consider a variety of staff-and their student peers-to be resources for sexual health information and services. Findings emphasize the importance of collaboration between health service staff and broader campus staff because students often turn to campus staff initially. Postsecondary students welcome opportunities to know a provider through interactive websites that include details about providers on campus; their decisions to seek sexual health care services are influenced by their perceptions of providers' characteristics and interpersonal skills. © 2014 Wiley Periodicals, Inc.

Insights into neural crest development and evolution from genomic analysis

PubMed Central

Simões-Costa, Marcos; Bronner, Marianne E.

2013-01-01

The neural crest is an excellent model system for the study of cell type diversification during embryonic development due to its multipotency, motility, and ability to form a broad array of derivatives ranging from neurons and glia, to cartilage, bone, and melanocytes. As a uniquely vertebrate cell population, it also offers important clues regarding vertebrate origins. In the past 30 yr, introduction of recombinant DNA technology has facilitated the dissection of the genetic program controlling neural crest development and has provided important insights into gene regulatory mechanisms underlying cell migration and differentiation. More recently, new genomic approaches have provided a platform and tools that are changing the depth and breadth of our understanding of neural crest development at a “systems” level. Such advances provide an insightful view of the regulatory landscape of neural crest cells and offer a new perspective on developmental as well as stem cell and cancer biology. PMID:23817048
