    We surveyed independent practice association (IPA) physician groups in California about their approaches to staffing, physician payment, and governance. Most IPAs desired more primary care physicians but not more specialists. Capitation was the major mode of remuneration for primary care physicians in 77 percent of IPAs, and for specialists in 30 percent of IPAs. Most IPAs also used financial incentives related to use of referral or ancillary services. Boards of directors were dominated by physicians, but governance tended to be centralized rather than highly democratic. We found that IPAs mirror many of the broader trends in physician staffing and physician payment that exist in managed care organizations.

    Value-based purchasing (VBP) favors provider organizations large enough to accept financial risk and develop care management infrastructure. Independent Practice Associations (IPAs) are a potential alternative for physicians to becoming employed by a hospital or large medical group. But little is known about IPAs. We selected four IPAs that vary in location, structure, and strategy, and conducted interviews with their president and medical director, as well as with a hospital executive and health plan executive familiar with that IPA. The IPAs studied vary in size and sophistication, but overall are performing well and are highly regarded by hospital and health plan executives. IPAs can grow rapidly without the cost of purchasing and operating physician practices and make it possible for physicians to remain independent in their own practices while providing the scale and care management infrastructure to make it possible to succeed in VBP. However, it can be difficult for IPAs to gain cooperation from hundreds to thousands of independent physicians, and the need for capital for growth and care management infrastructure is increasing as VBP becomes more prevalent and more demanding. Some IPAs are succeeding at VBP. As VBP raises the performance bar, IPAs will have to demonstrate that they can achieve results equal to more highly capitalized and tightly structured large medical groups and hospital-owned practices. Physicians should be aware of IPAs as a potential option for participating in VBP. Payers are aware of IPAs; the Medicare ACO program and health insurer ACO programs include many IPAs.

    Pay-for-performance, public reporting, and accountable care organization programs place pressures on physicians to use health information technology and organized care management processes to improve the care they provide. But physician practices that are not large may lack the resources and size to implement such processes. We used data from a unique national survey of 1,164 practices with fewer than twenty physicians to provide the first information available on the extent to which independent practice associations (IPAs) and physician-hospital organizations (PHOs) might make it possible for these smaller practices to share resources to improve care. Nearly a quarter of the practices participated in an IPA or a PHO that accounted for a significant proportion of their patients. On average, practices participating in these organizations provided nearly three times as many care management processes for patients with chronic conditions as nonparticipating practices did (10.4 versus 3.8). Half of these processes were provided only by IPAs or PHOs. These organizations may provide a way for small and medium-size practices to systematically improve care and participate in accountable care organizations.

  4. Reflections on independence in nurse practitioner practice.

    PubMed

    Weiland, Sandra A

    2008-07-01

    To examine factors that influence the ability of nurse practitioners (NPs) to practice as independent primary care providers. Extensive literature search on CINAHL, OVID, MEDLINE, Internet journal sources, and professional association Web sites. The legal authority for NPs to practice independently is recognized; however, the ability to put that authority into practice is undermined by the historical failure of political, professional, and social entities to recognize NPs as providers capable of providing primary care autonomously. Nonrecognition is responsible for complex reimbursement policies (both federal and state) that economically and professionally restrain the NP role; hence, NPs remain in a financially dependent relationship despite 40 years of proven safe practice. NPs must articulate their independence as practitioners more vociferously in order to meet society's healthcare requirements, as well as to attain professional fulfillment and forge collegial relationships. NPs will never be seen as members of a profession by either themselves or others without the practicality of independence and autonomy. Although legal independence is a fact, real practice independence in the pragmatic sense is contingent upon reimbursement. Without fiscal sustainability, practice independence is an impossibility. And, without professional autonomy, NPs will have only an employee's voice in the dynamic healthcare system in which they are really key players in providing healthcare services to the poor and undeserved populations.

  7. Independence as a practice issue in occupational therapy: the safety clause.

    PubMed

    2002-01-01

    This article reports findings from interviews that explored the meanings occupational therapists attach to independence as a value and a therapeutic goal in interactions with elderly clients. Through a historical review of the literature, we trace the changing use of this term and identify two analytically distinct concepts associated with it: independence as self-reliance in activity and independence as autonomy, self-determination, or choice. We show how the latter has emerged in contemporary service contexts to represent an ideal of client-centered practice for persons with chronic disabilities, such as frail elderly clients. Using a "critical incident" interview approach with 12 Australian occupational therapists, we identified the therapists' explicit and implicit understandings of independence as a value concept and practice issue. Our findings suggest that a mismatch often exists between idealized and practice-based talk about independence and that therapists narrativize this opposition around what we call "the safety clause." That is, therapists invoke concerns about safety and duty of care as a caveat to implementing their independence ideals and justifying the retention of professional control. We identify key issues that therapists need to address if the rhetoric of independence-related client-centered practice is to be achieved in reality.

  9. Evidence against associative blocking as a cause of cue-independent retrieval-induced forgetting.

    PubMed

    Hulbert, Justin C; Shivde, Geeta; Anderson, Michael C

    2012-01-01

    Selectively retrieving an item from long-term memory reduces the accessibility of competing traces, a phenomenon known as retrieval-induced forgetting (RIF). RIF exhibits cue independence, or the tendency for forgetting to generalize to novel test cues, suggesting an inhibitory basis for this phenomenon. An alternative view (Camp, Pecher, & Schmidt, 2007; Camp et al., 2009; Perfect et al., 2004) suggests that using novel test cues to measure cue independence actually engenders associative interference when participants covertly supplement retrieval with practiced cues that then associatively block retrieval. Accordingly, the covert-cueing hypothesis assumes that the relative strength of the practiced items at final test – and not the inhibition levied on the unpracticed items during retrieval practice – underlies cue-independent forgetting. As such, this perspective predicts that strengthening practiced items by any means, even if not via retrieval practice, should induce forgetting. Contrary to these predictions, however, we present clear evidence that cue-independent forgetting is induced by retrieval practice and not by repeated study exposures. This dissociation occurred despite significant, comparable levels of strengthening of practiced items in each case, and despite the use of Anderson and Spellman's original (1995) independent probe method criticized by covert-cueing theorists as being especially conducive to associative blocking. These results demonstrate that cue-independent RIF is unrelated to the strengthening of practiced items, and thereby fail to support a key prediction of the covert-cueing hypothesis. The results, instead, favor a role of inhibition in resolving retrieval interference. © 2011 Hogrefe Publishing

  10. Consumer perspectives on nurse practitioners and independent practice.

    The purposes of this study were to report the results of a survey for determining the feasibility and sustainability of independently managed nurse practitioner (NP) practices, to identify the characteristics of consumers who would likely choose an independent NP practice, to assess consumer needs, and to define a target market for competitively positioning NPs. An anonymous electronic survey of 1000 employees (response rate = 21%) at a large nonprofit organization in King County, Washington. This organization employs persons in a wide range of socioeconomic and vocational situations. Descriptive statistics and chi-square analyses were applied to determine associations between demographic characteristics and having used an NP or having the intent to use an independent NP practice. Most respondents knew about NPs, and the majority had seen an NP for their care. Most were satisfied or very satisfied with NP care. A much larger percentage (90%) than previous studies knew about NPs; 58% had seen an NP for their care, making NPs the most used practitioner alternative to physicians. Evidence suggests that NP users are more likely to be female and younger. Eighty-two percent of NP users were satisfied or very satisfied with the care they had received compared to a 70% satisfaction rate for current providers. Women, relatively younger respondents, those who had seen a physician assistant or NP, and those who considered NPs to provide quality and more personalized care were significantly more likely to indicate that they would choose an independent NP practice in their community. Based on a standard marketing formula, 30% of the sample in this study would be expected to change their health care to such a practice. This is the first descriptive study to suggest widespread acceptance of NPs as independent practitioners. Compared to a 1985 study of Seattle residents, consumers are far more likely to know about NPs. Consumer studies such as this one identify the characteristics

  12. Health maintenance organizations, independent practice associations, and cesarean section rates.

    PubMed

    Tussing, A D; Wojtowycz, M A

    1994-04-01

    This study tests two hypotheses: that a given delivery is less likely to be by cesarean section (c-section) in an HMO (closed-panel health maintenance organization) or IPA (independent practice association), than in other settings; and that where HMO and IPA penetration is high, the probability of a c-section will be reduced for all deliveries, whether in prepaid groups or not. A data set consisting of 104,595 obstetric deliveries in New York state in 1986 is analyzed. A series of probit regressions is estimated, in which the dependent variable is either the probability that a given delivery is by c-section, or that a given delivery will result in a c-section for dystocia or fetal distress. The Live Birth File is linked with SPARCS hospital discharge data and other variables. HMO setting reduces the probability of a cesarean section by 2.5 to 3.0 percentage points. However, this result is likely to be partly an artifact of offsetting diagnostic labeling and of choice of method of delivery, given diagnosis; a better estimate of the effect of HMO setting is -1.3 percentage points. IPA setting appears to affect the probability of a cesarean section even less, perhaps not at all. And HMO and IPA penetration in a region, as measured by HMO and IPA deliveries, respectively, as a percent of all deliveries, has relatively large depressing effects on the probability of a cesarean section. Ceteris paribus, the probability of a c-section is lower for an HMO delivery than for a fee-for-service delivery; however, HMO effects are smaller than previously reported in the literature for other types of inpatient care. For IPA deliveries, the effects are still smaller, perhaps nil. However, HMO and IPA penetration, possibly measuring the degree of competition in obstetrics markets, have important effects on c-section rates, not only in HMO/IPA settings, but throughout an area. These results appear to have important implications for public policy.

    2014-12-01

    The purpose of this study was to determine the perceived level of preparedness Maine Independent Practice Dental Hygienists (IPDHs) received from their standard undergraduate dental hygiene education, and recognize areas necessary for further preparation in order to explore careers beyond the private practice dental model. A convenience sample of 6 IPDHs participated in a survey exploring their educational experience in public health and alternative practice settings. The survey also asked for their recommendations to advance dental hygiene education to meet the needs of those wishing to pursue alternative practice careers. This study found that participants felt underprepared by their dental hygiene education with deficits in exposure to public health, business skills necessary for independent practice, communication training and understanding of situations which require referral for treatment beyond the IPDH scope of practice. As the dental hygiene profession evolves, dental hygiene education must as well. The IPDH participants' recommendations for dental hygiene programs include increased exposure to alternative settings and underserved populations as well as elective courses for those students interested in alternative practice and business ownership.

    1998-01-01

    The purpose of this pilot study was to gather demographic data about six Colorado dental hygienists who were practicing independently and their practices as well as assess productivity and service mix, evaluate structure and process, and compare the findings in these practices to those of a study of California Health Manpower Pilot Project #139. A convenience sample of six dental hygiene independent practices was studied. A 21-item survey was distributed by mail to obtain demographic and practice information. Weekly surveys tracking patient visits and services provided were completed for three months. A general office audit to evaluate structure and a record audit of 22 patient records to evaluate process were conducted during visits at each practice site. The overall responses for each phase of this study were tabulated and frequencies were calculated using the SPSS/PC+ statistical package. The dental hygienists had practiced for an average of 13 years prior to establishing their practices. Four of the six practices were office-based, one was institution-based, and one was office- and institution-based. Health history, extraoral/intraoral examination, periodontal probing, adult prophylaxis, and oral hygiene instruction were provided during a majority of patient visits. The general office audit revealed compliance with infection control, office protocols for emergency situations, and practice management protocols. The patient record audit indicated a high standard for process of care for the practice sites. The six practices revealed a variety of backgrounds among the dental hygienists and diverse practice characteristics regarding both the populations served and practice settings. The services provided were consistent with allowable services for unsupervised practice. Compliance with specific guidelines was verified during the general office and patient record audits. Consistent with the findings of California Health Manpower Pilot Project #139, the care provided

    Beach, M Miles; Shulman, Jay D; Johns, Glenna; Paas, Jeffrey C

    2007-01-01

    This paper deals with the economics of the independent dental hygiene practice. Using historical data from dental practices in Cincinnati, Ohio, we developed a business model for an independent hygiene practice. We tested the sensitivity of the model to variations in key assumptions (initial capitalization, interest, employee salary, and owner's draw). We described the profitability on the basis of the breakeven point. Under the most permissive regulatory and financial environment, the practice would breakeven after 26 months. However, the owner would not equal the earnings of a salaried hygienist until the initial loan is paid off after 7 years. The model was not sensitive to 20 percent changes in the key assumptions. Under ideal circumstances, an independent hygiene practice could be profitable.

  19. Associations between children’s independent mobility and physical activity

    PubMed Central

    2014-01-01

    Background Independent mobility describes the freedom of children to travel and play in public spaces without adult supervision. The potential benefits for children are significant such as social interactions with peers, spatial and traffic safety skills and increased physical activity. Yet, the health benefits of independent mobility, particularly on physical activity accumulation, are largely unexplored. This study aimed to investigate associations of children’s independent mobility with light, moderate-to-vigorous, and total physical activity accumulation. Methods In 2011 - 2012, 375 Australian children aged 8-13 years (62% girls) were recruited into a cross-sectional study. Children’s independent mobility (i.e. independent travel to school and non-school destinations, independent outdoor play) and socio-demographics were assessed through child and parent surveys. Physical activity intensity was measured objectively through an Actiheart monitor worn on four consecutive days. Associations between independent mobility and physical activity variables were analysed using generalized linear models, accounting for clustered sampling, Actiheart wear time, socio-demographics, and assessing interactions by sex. Results Independent travel (walking, cycling, public transport) to school and non-school destinations were not associated with light, moderate-to-vigorous and total physical activity. However, sub-analyses revealed a positive association between independent walking and cycling (excluding public transport) to school and total physical but only in boys (b = 36.03, p < 0.05). Frequent independent outdoor play (three or more days per week) was positively associated with light and total physical activity (b = 29.76, p < 0.01 and b = 32.43, p = 0.03, respectively). No significant associations were found between independent outdoor play and moderate-to-vigorous physical activity. When assessing differences by sex, the observed significant

    2009-05-01

    In 2006, the Ministry of Health and Welfare revised the regulations regarding the Medical Service Law. The amendments stipulate that all healthcare institutions are required to implement infection control programs. However, small hospitals and clinics have no clinical microbiology laboratories, whereas medium-sized hospitals have few medical technologists and the outsourcing of microbiology tests to independent laboratories is common. The decreasing number of laboratories and recent outsourcing tendency reflect the increasing commercialization, and, with it, the escalating number of commercially operating chains. Each independent laboratory is responsible for supporting activities related to the surveillance, control, and prevention of healthcare-associated infections in the associated small and medium-sized hospitals. The people responsible for infection control in these hospitals usually do not have a background in microbiology. The evaluation of communication between independent laboratory staff and hospital personnel, and rapid turnaround time of microbiology laboratory test reports are important elements ensuring the quality of independent laboratory work. With the pressures of financial constraints in the Japanese medical insurance system, the development of a cost-effective and practical protocol for quality assurance is a real dilemma.

  3. Attitudes of Dental Hygienists towards Independent Practice and Professional Autonomy.

    PubMed

    Catlett, April

    2016-08-01

    The purpose of this cross-sectional, quantitative research was to examine if registered dental hygienists feel competent to work independently based on regulations of dental supervision. A stratified sample of 360 dental hygienists from 8 states completed the Dempster Practice Behaviors Scale survey. ANOVA and MANOVA analyses revealed how state dentist supervision level, age, degree of education, employment status, gender and years of clinical experience affect the perceived autonomy of professional dental hygienists. The response rate included 360 dental hygienists from 8 states. According to the findings age, education level and gender affected the hygienist's level of autonomy. In all 8 states, the registered dental hygienists have a high level of autonomy and feel competent to work independently. The DPBS scores of the sample registered dental hygienists suggest that they feel prepared and competent to perform preventive dental hygiene services without dentist supervision. The attitudes of the dental hygienist sample from each of the 4 state dentist supervision levels supports a move toward achieving professional jurisdiction of preventive dental care within the U.S. Copyright © 2016 The American Dental Hygienists’ Association.

    Despite the salience of behavioral autonomy and independence to parent-child interactions during middle adolescence, little is known about parenting processes pertinent to youth autonomy development for Latino families. Among a diverse sample of 684 Latino-origin parent-adolescent dyads in Houston, Texas, this study examines how parents' cultural orientations are associated directly and indirectly, through parental beliefs, with parenting practices giving youth behavioral autonomy and independence. Informed by social domain theory, the study's parenting constructs pertain to youth behaviors in an "ambiguously personal" domain-activities that adolescents believe are up to youth to decide, but which parents might argue require parents' supervision, knowledge, and/or decision-making. Results for latent profile analyses of parents' cultural identity across various facets of acculturation indicate considerable cultural heterogeneity among Latino parents. Although 43% of parents have a Latino cultural orientation, others represent Spanish-speaking/bicultural (21%), bilingual/bicultural (15%), English-speaking/bicultural (15%), or US (6%) cultural orientations. Structural equation modeling results indicate that bilingual/bicultural, English-speaking/bicultural, and US-oriented parents report less emphasis on the legitimacy of parental authority and younger age expectations for youth to engage in independent behaviors than do Latino-oriented parents. Parental beliefs endorsing youth's behavioral independence and autonomy, in turn, are associated with less stringent parental rules (parental report), less parental supervision (parental and youth report), and more youth autonomy in decision-making (parental and youth report). Evidence thus supports the idea that the diverse cultural orientations of Latino parents in the US may result in considerable variations in parenting processes pertinent to Latino adolescents' development.

    Attitudes of dentists and dental hygienists towards extended scope and independent dental hygiene practice are described in several studies, but the results are heterogenous. The purpose of this systematic review was to compare the attitudes of dentists and dental hygienists towards extended scope and independent dental hygiene practice. PubMed, AMED and CINAHL were screened by two independent assessors to identify relevant studies. Only quantitative studies that reported the percentages of dentists' and dental hygienists' attitude towards extended scope and independent dental hygiene practice were included. The random-effects model was used to synthesise possible heterogenous influences. Meta proportions with regard to a positive attitude towards extended scope of practice are 0.54 for dentists and 0.81 for dental hygienists. Meta proportions of a positive attitude towards independent practice are 0.14 for dentists and 0.59 for dental hygienists. A meta analysis with regard to negative attitudes could only be performed on extended scope of practice and did not reveal a difference between the two professions. We obtained homogeneous outcomes of the studies included regarding negative attitudes of dentists . A minority of dentists hold negative attitudes towards extended scope of dental hygiene practice. Study outcomes regarding negative attitudes of dental hygienists were heterogeneous. Positive attitudes are present among a majority of dentists and dental hygienists with regard to extended scope of dental hygiene practice, while for independent dental hygiene practice this holds for a minority of dentists and a majority of dental hygienists. © 2016 FDI World Dental Federation.

    To identify risk factors for cariogenic feeding practices in the first year of life. Cohort study. 500 children born within the public health care system in São Leopoldo, Brazil, were recruited in a follow-up program. Anthropometric and demographic data were collected soon after birth; data on feeding practices were assessed at 12 months of age using a standardised questionnaire; clinical examination at 4 years of age allowed identification of cariogenic feeding practices in the first year of life and to quantify their relative risks. In the present study, the attributable risks of each child were summed, and the outcome was assessed for the upper quartile of scores for cariogenic feeding practices. Adjusted relative risks for the outcome were estimated using robust Poisson regression models. A total of 327 children comprised the final study sample, i.e. were followed from birth to 4 years of age. Multivariate analysis showed that the risk of cariogenic feeding practices doubled in children from mothers with less than 5 years of education (RR 2.19, 95%CI 1.26-3.82) and was 70% higher in children from mothers with 5-8 years of education when compared with maternal education >8 years. The other independent variables were not associated with the outcome. Low maternal education is a risk factor for cariogenic feeding practices, independently of other factors. Mothers with low educational levels should be the focus of child health promotion interventions, especially those aimed at controlling dental caries.

  8. Relationships among moral distress, level of practice independence, and intent to leave of nurse practitioners in emergency departments: results from a national survey.

    The aims of this research study were to investigate moral distress among emergency department (ED) nurse practitioners (NPs) and examine relationships between moral distress and level of practice independence as well as intent to leave a position. Moral distress has been studied regarding registered nurses and physicians (MDs) but less so in NPs. It is important to explore moral distress in NPs because they tread a unique path between nursing and physician roles. Moral distress may play a significant role in staff nurses' intention to leave practice, and level of practice independence is found to have a relationship with NPs' intention to leave. A convenience sample of ED NPs was obtained from a mailing list of a national nursing specialty organization, the Emergency Nurses Association. Using a correlational design, survey methods assessed moral distress with the Moral Distress Scale-Revised (MDS-R), level of practice independence with the Dempster Practice Behavior Scale, and intent to leave with self-report. Correlational and regression analyses of data were conducted to characterize moral distress among ED NPs and associations between moral distress, level of practice independence, and intent to leave. Results found ED NPs do experience moral distress with poor patient care results from inadequate staff communication and working with incompetent coworkers in their practice. The MDS-R was a significant predictor of intention to leave among respondents. This study is the first of its kind to explore moral distress in ED NPs. Results suggest moral distress influences ED NPs' intent to leave their position. Further studies are needed to explore the findings from this research and to formulate interventions to alleviate moral distress in ED NPs and improve retention in the clinical setting.

    Among early adolescents (10–14 years), poor diet quality along with physical inactivity can contribute to an increased risk of obesity and associated biomarkers for chronic disease. Approximately one-third of United States (USA) children in this age group are overweight or obese. Therefore, attention to factors affecting dietary intake as one of the primary contributors to obesity is important. Early adolescents consume foods and beverages during eating occasions that occur with and without parental supervision. Parents may influence eating behaviors of early adolescents during eating occasions when they are present or during independent eating occasions by engaging in practices that affect availability of foods and beverages, and through perceived normative beliefs and expectations for intake. Therefore, the purpose of this article was to describe the influence of parenting practices on eating behaviors in general and when specifically applied to independent eating occasions of early adolescents. This information may be helpful to inform parenting interventions targeting obesity prevention among early adolescents focusing on independent eating occasions. PMID:26506384

    To identify associations between maternal restrictive feeding practices for child weight control and sociodemographic, behavioral, dietetic, and anthropometric characteristics. Cross-sectional study with mothers of children aged 2-8 years. Maternal feeding practices were measured by the Comprehensive Feeding Practices Questionnaire, in private schools in Brazil. Bivariate and multivariate associations were performed, using nonparametric analyses to estimate odds ratios and significance levels. Maternal restrictive feeding practices for weight control were independently associated with the mother's perception of her child being a little overweight/overweight/obese (OR=4.61, p=0.001), greater concern about the child's overweight (OR=2.61, p<0.001), child's overweight/obesity/severe obesity (OR= 2.18, p<0.001), and the child's greater intake of ultra-processed foods (OR=1.40, p=0.026). In this study, the risk variables identified for the use of the maternal restrictive feeding practices to control the child's weight can be used to provide education and guidance interventions in health and education networks directed to groups with similar characteristics to those of the studied population.

    Catering businesses continue to be the most common setting for foodborne disease outbreaks. In a study of catering businesses in England and Wales, operational practices relating to the supply, preparation, and service of food in 88 businesses associated with outbreaks were compared with those practices at 88 control businesses. Operational practices did not differ significantly between case and control businesses but larger small medium-size enterprise (SME) businesses were more likely to be associated with foodborne disease outbreaks than were micro-SME businesses. Businesses associated with outbreaks of Salmonella infection were less likely to use local or national suppliers but instead used regional suppliers, especially for eggs. This practice was the only significantly independent operational practice associated with outbreaks of Salmonella infection. Regional egg suppliers also were more likely to be used by businesses associated with outbreaks attributed to food vehicles containing eggs. Businesses associated with egg-associated outbreaks were less likely to use eggs produced under an approved quality assurance scheme, suggesting that the underlying risk associated with using regional suppliers may relate to the use of contaminated eggs.

    With increasing pressure to produce high standardized test scores, school systems will be looking for the surest ways to increase scores. Decision makers uninformed about the value of inquiry science may recommend more direct teaching methods and curricula in the hope that students will more quickly accumulate factual information for high test scores. This researcher and other proponents of inquiry science suggest that the best preparation for any test is the ability to use all available information and problem solving skills to think through to a solution. This study proposes to test the theory that inquiry problem solving skills need to be modeled and practiced in increasingly independent situations to be learned. Students tend to copy what they have been led to believe is correct, and to avoid continued copying, their skills must be applied in new situations requiring independent practice and improvement. This study follows ten sixth grade students, selected for maximum variation, as they participate in a series of five cycles of modeling and practicing inquiry science investigations as part of an ongoing unit on water quality. The cycles were designed to make the students increasingly independent in their use of inquiry. The results showed that all ten students made significant progress from copying teacher modeling in investigation #1 towards independent inquiry, with nine of the ten achieving acceptable to good beginning independent inquiry in investigation #5. Each case was analyzed independently using such case study methodology as pattern matching, case study protocols, and theoretical propositions. Constant comparison and other case study methods were used in a cross-case analysis. Eight cases confirmed a matching set of propositions and the hypothesis, in literal replication, and the other two cases confirmed a set of propositions and the hypothesis through theoretical replication. The study suggests to educators that repeated cycles of modeling and

    The nature of the work that NQGPs are undertaking in their transition to independent practice is changing; current training may not fully prepare them for this new peripatetic role, as indicated by rising numbers of reports of poor performance in this group. Educational support at the time of transition from general practitioner (GP) training to independent practice had previously demonstrated benefits, but many formal schemes have finished. This study aimed to map out the current provision of educational support provided by the UK deaneries for NQGPs and to explore NQGPs' perceptions of the present transition from registrar to independent practitioner. Questionnaire surveys of deanery provision and semi-structured telephone interviews of a purposeful sample of newly qualified GPs across the UK. Interviews were thematically analysed. Deanery provision of educational support to NQGPs varies across the UK. Telephone interviews highlighted the transformation as problematic; NQGPs perceived that independent practice was substantially different from being in a training post - locum work, isolation and accessing educational opportunities were concerns. NQGPs frequently expressed a desire for more formalised relationships with mentors, senior colleagues or peer groups, to support their shift. As NQGPs increasingly find themselves working as locums, lacking the opportunity for stable work-based relationships, and with an increase in medical errors being reported in this group of doctors, it is suggested that there is a need to reconsider the educational support required to facilitate the transition in the early years of independent general practice.

    The graduate medical education system is tasked with training competent and autonomous health care providers while also improving patient safety, delivering more efficient care, and cutting costs. Concerns about resident autonomy and preparation for independent and safe practice appear to be growing, and the field of surgery faces unique challenges in preparing graduates for independent practice. Multiple factors are contributing to an erosion of resident autonomy and decreased operative experience, including differing views of autonomy, financial forces, duty hours regulations, and diverse community health care needs. Identifying these barriers and developing solutions to overcome them are vital first steps in reversing the trend of diminishing autonomy in surgical residency training. This Commentary highlights the problem of decreasing autonomy, outlines specific threats to resident autonomy, and discusses potential solutions to mitigate their impact on the successful transition to independent practice.

    Nurses are able to prescribe independently from a list of nearly 250 prescription only medicines for a range of over 100 medical conditions or, from the whole British National Formulary as a supplementary prescriber. There is some evidence available on the prescribing practices of district nurses and health visitors and early independent extended prescribers. Little or no attention has focussed on supplementary nurse prescribing. To provide an overview of the prescribing practices of independent extended/supplementary nurse prescribers and the factors that facilitate or inhibit prescribing. National questionnaire survey. United Kingdom. A convenience sample of 868 qualified independent extended/supplementary nurse prescribers self-completed a written questionnaire. A total of 756 (87%) used independent extended prescribing; 304 (35%) used supplementary prescribing to treat a range of chronic conditions (including asthma, diabetes and hypertension); 710 (82%) nurses worked in primary care. Nurses in general practice reported the largest number of reasons preventing prescribing. Reasons included the inability to computer generate prescriptions and to implement the Clinical Management Plan. Nurses in primary care reported more continuing professional development needs. These needs included update on prescribing policy and the treatment management of conditions. A total of 277 (32%) nurses were unable to access continuing professional development. Independent extended/supplementary nurse prescribers work predominantly in primary care and do prescribe medicines. These nurses are highly qualified and have many years clinical experience. Supplementary prescribing is used by a minority of nurses. Implementing the Clinical Management Plan is a barrier preventing the use of this mode of prescribing. The continuing professional development needs of independent extended/supplementary nurse prescribers are frequently unmet. It will become increasingly important that these needs

    The paper describes a small-scale enquiry with UK-based general practice specialty trainees (GPSTs) at the time of transition from training to independent practice. It aimed to identify whether they were supported in making this transition through attending practice-based small group learning (PBSGL) sessions. Participants in the study reported that the sessions helped them to consolidate their learning from their third year of training (GPST3), improved their ability to identify and use evidence in practice, and shifted the focus of their learning needs away from the two UK general practice postgraduate exams (applied Knowledge Test or aKT; and Clinical Skills assessment or CSa) and towards 'real world' practice. The two pilot groups have become established as means of peer support and continue to meet, with small changes in composition. The work has led to the wider roll out of PBSGL for newly qualified GPs across Wessex.

    To determine factors associated with damage accrual in a prospective cohort of patients with SLE. Patients with SLE who attended the Lupus Clinic at Monash Health, Australia, between 2007 and 2013 were studied. Clinical variables included disease activity (Systemic Lupus Erythematosus Disease Activity Index-2K, SLEDAI-2K), time-adjusted mean SLEDAI, cumulative glucocorticoid dose and organ damage (Systemic Lupus International Collaborating Clinics Damage Index (SDI)). Multivariate logistic regression analyses were performed to identify factors associated with damage accrual. A total of 162 patients were observed over a median (IQR) 3.6 (2.0-4.7) years. Seventy-five per cent (n=121) of patients received glucocorticoids. Damage accrual was significantly more frequent in glucocorticoid-exposed patients (42% vs 15%, p<0.01). Higher glucocorticoid exposure was independently associated with overall damage accrual after controlling for factors including ethnicity and disease activity and was significant at time-adjusted mean doses above 4.42 mg prednisolone/day; the OR of damage accrual in patients in the highest quartile of cumulative glucocorticoid exposure was over 10. Glucocorticoid exposure was independently associated with damage accrual in glucocorticoid-related and non-glucocorticoid related domains of the SDI. Glucocorticoid use is independently associated with the accrual of damage in SLE, including in non-glucocorticoid related domains.

    Medical trainees demonstrate a reluctance to ask for help unless they believe it is absolutely necessary, a situation which could impact on the safety of patients. This study aimed to develop a theoretical exploration of the pressure on medical trainees to be independent and to generate theory-based approaches to the implications for patient safety of this pressure towards independent working. In Phase 1, 88 teaching team members from internal and emergency medicine were observed during clinical activities (216 hours), and 65 participants completed brief interviews. In Phase 2, 36 in-depth interviews were conducted using video vignettes. Data collection and analysis employed grounded theory methodology. Participants conceived that the pressure towards independence in clinical work originated in trainees' desire to lay claim to the identity of a doctor (as a member of a group of autonomous high achievers), and in organisational issues such as heavy workloads and constant evaluations. The identity and organisational issues related to the pressure towards independence were explored through the lenses of established theories from education and psychology. Consideration of Lave and Wenger's situated learning theory suggests that giving attention to the 'independent doctor' ideal, through measures such as involving trainees when their supervisors ask for help, could impact the safety of teaching team practice. Amalberti et al.'s migration model explains how pressures to maximise productivity and individual gain may cause teaching teams to migrate beyond the boundaries of safe practice and suggests that managing triggers (such as workload and high-stakes evaluations) for violations of safe practice might improve safety. Implementation and evaluation of these theory-based approaches to the safety of teaching team practice would contribute to a better understanding of the links between trainee independence and patient safety.

    Postgraduate medical education training programs strive to prepare their trainees optimally for independent practice. Several studies have shown, however, that new consultants feel inadequately prepared for practice, and that this increases the risk of stress and burnout. To analyze across specialties for which tasks and themes new consultants feel inadequately prepared. And, to identify themes that need improved attention in postgraduate medical education programs or after registration. 330 New consultants from all hospital specialities with accredited training programs who completed their training in the north-eastern educational region of The Netherlands between 2004 and 2010 received a questionnaire which was based on a previously validated generic task inventory. 143 respondents (43%) returned the questionnaire. They felt excellently prepared for 40 tasks, well prepared for 25 tasks, marginally sufficiently prepared for 18 tasks and insufficiently prepared for 8 tasks. Preparedness scores were lowest for tasks concerning management administration and leadership, research, end-of-life care, and patient safety-related communication. Surgical specialists felt better prepared for practice than medical specialists, which could not be explained by differences in general self-efficacy. Although new consultants felt well prepared for medical tasks, the scores of more generic tasks indicate that the alignment between the different phases of the medical education continuum and independent practice needs improvement.

    Pregnancy is the most crucial nutritionally demanding period of every woman's life. The high demand of nutrients to deposit energy in the form of new tissue, growth of existing maternal tissues such as breast and uterus and increased energy requirements for tissue synthesis makes pregnant women more vulnerable to malnutrition. Dietary practice is defined as an observable actions or behavior of dietary habit and can be classified as good dietary practices and poor dietary practices. The incidence of dietary inadequacies as a result of dietary habits and patterns in pregnancy is higher during pregnancy when compared to any other stage of the life cycle. Thus, this study aimed to assess dietary practices and associated factors during pregnancy in Bahir Dar town, Northwest Ethiopia. A community based cross sectional study was conducted from March 1 to April 1, 2016. A total of 616 pregnant women were participated in the study. All eligible pregnant women were identified through house-to-house visit with the help of health extension workers. Cluster sampling was used to select eligible pregnant women. The data were collected using interviewer administered questionnaire prepared in English and translated in to Amharic. Data were analyzed by using Statistical Package for Social Sciences (SPSS) version 20. Multivariate logistic regression analysis was employed to identify factors associated with dietary practices. This study has shown that 39.3% of the study participants had good dietary practices and the rest 60.7% of pregnant women reported poor dietary practices. Concerning dietary knowledge, 61.4% of the study participants had good dietary knowledge while 38.6% had poor dietary knowledge. Husband income, ownership of radio, history of disease and dietary knowledge were shown to have significant association (P < 0.05) with dietary practices. Dietary practices of pregnant women in the study area was suboptimal. Husband income, ownership of radio, history of disease

    Current evidence suggests physical activity (PA) and sleep are important for cognitive health; however, few studies examining the role of PA and sleep for cognitive health have measured these behaviors objectively. We cross-sectionally examined whether 1) higher PA is associated with better cognitive performance independently of sleep quality; 2) higher sleep quality is associated with better cognitive performance independently of PA; and 3) whether higher PA is associated with better sleep quality. We measured PA, subjective sleep quality using the Pittsburgh Sleep Quality Index (PSQI), and objective sleep quality (i.e., fragmentation, efficiency, duration, and latency) using the MotionWatch8© in community-dwelling adults (N = 137; aged 55+). Cognitive function was indexed using the Alzheimer's Disease Assessment Scale-Plus. Correlation analyses were performed to determine relationships between PA, sleep quality, and cognitive function. We then used latent variable modelling to examine the relationships of PA with cognitive function independently of sleep quality, sleep quality with cognitive function independently of PA, and PA with sleep quality. We found greater PA was associated with better cognitive performance independently of 1) PSQI (β= -0.03; p < 0.01); 2) sleep fragmentation (β= -0.02; p < 0.01); 3) sleep duration (β= -0.02; p < 0.01); and 4) sleep latency (β= -0.02; p < 0.01). In addition, better sleep efficiency was associated with better cognitive performance independently of PA (β= -0.01; p = 0.04). We did not find any associations between PA and sleep quality. PA is associated with better cognitive performance independently of sleep quality, and sleep efficiency is associated with better cognitive performance independently of PA. However, PA is not associated with sleep quality and thus PA and sleep quality may be related to cognitive performance through independent mechanisms.

    Objective To quantify the role of practice characteristics in patient-specific receipt of dental diagnostic radiographic services. Data Source/Study Setting Florida Dental Care Study (FDCS). Study Design The FDCS was a 48-month prospective observational cohort study of community-dwelling adults. Participants' dentists were asked to complete a questionnaire about their practice characteristics. Data Collection/Extraction Methods In-person interviews and clinical examinations were conducted at baseline, 24, and 48 months, with 6-monthly telephone interviews in between. A single multivariate (four radiographic service outcomes) multivariable (multiple explanatory covariates) logistic regression was used to model service receipts. Principal Findings These practice characteristics were significantly associated with patient-specific receipt of radiographic services: number of different practices attended during follow-up; dentist's rating of how busy the practice was; typical waiting time for a new patient examination; practice size; percentage of patients that the dentist reported as interested in details about the condition of their mouths; percentage of African American patients in the practice; percentage of patients in the practice who do not have dental insurance; and dentist's agreement with a statement regarding whether patients should be dismissed from the practice. Effects had differential magnitudes and directions of effect, depending upon radiograph type. Conclusions Practice characteristics were significantly associated with patient-specific receipt of services. These effects were independent of patient-specific disease level and patient-specific sociodemographic characteristics, suggesting that practitioners do influence receipt of these diagnostic services. These findings are consistent with the conclusion that practitioners act in response to a mix of patients' interests, economic self-interests, and their own treatment preferences. PMID:16987308

    Purpose. The purpose of the study was to examine the independent associations of adiposity and cardiorespiratory fitness with clustered cardiometabolic risk. Methods. A cross-sectional sample of 192 adolescents (118 boys), aged 14–16 years, was recruited from a South Lanarkshire school in the West of Scotland. Anthropometry and blood pressure were measured, and blood samples were taken. The 20 m multistage fitness test was the indicator of cardiorespiratory fitness (CRF). A clustered cardiometabolic risk score was constructed from HDL-C (inverted), LDL-C, HOMA, systolic blood pressure, and triglycerides. Interleukin-6, C-reactive protein, and adiponectin were also measured and examined relative to the clustered cardiometabolic risk score, CRF, and adiposity. Results. Although significant, partial correlations between BMI and waist circumference (WC) and both CRF and adiponectin were negative and weak to moderate, while correlations between the BMI and WC and CRP were positive but weak to moderate. Weak to moderate negative associations were also evident for adiponectin with CRP, IL-6, and clustered cardiometabolic risk. WC was positively associated while CRF was negatively associated with clustered cardiometabolic risk. With the additional adjustment for either WC or CRF, the independent associations with cardiometabolic risk persisted. Conclusion. WC and CRF are independently associated with clustered cardiometabolic risk in Scottish adolescents. PMID:23984329

    Excess body weight is associated with an imbalance between energy expenditure and dietary intake but evidence on the association between diet quality and body composition remains equivocal. Rather than relying on differences in diet quality between overweight/obese and normal weight adults, this study examined the association between the Healthy Eating Index 2010 (HEI-2010) and body fatness on a continuous scale, independent of physical activity (PA). Further the association between components of the HEI-2010 and risk for overweight/obesity was explored. 407 adults (27.6 ± 3.7 years) provided at least two 24-hour diet recalls over a period of 14 days, which were used to calculate the HEI-2010. Percent body fat (BF) was assessed via dual X-ray absorptiometry and PA was determined via a multi-sensor device, worn over a period of 10 days. PA was a stronger contributor to the variability in BF than the HEI-2010 and the association between HEI-2010 and BF was significant only in men. Particularly a high consumption of protein, sodium and empty calories increased the risk for overweight/obesity. Adherence to dietary guidelines positively affects body fatness in men, independent of PA. In contrast to current dietary recommendations, the risk for overweight/obesity was increased with a higher protein intake.

    ageing is highly associated with neurodegeneration and atrophy of the brain. Evidence suggests that personality variables are risk factors for reduced brain volume. We examine whether falls-related self-efficacy is independently associated with brain volume. a cross-sectional analysis of whether falls-related self-efficacy is independently associated with brain volumes (total, grey and white matter). Three multivariate regression models were constructed. Covariates included in the models were age, global cognition, systolic blood pressure, functional comorbidity index and current physical activity level. MRI scans were acquired from 79 community-dwelling senior women aged 65-75 years old. Falls-related self-efficacy was assessed by the activities-specific balance confidence (ABC) scale. after accounting for covariates, falls-related self-efficacy was independently associated with both total brain volume and total grey matter volume. The final model for total brain volume accounted for 17% of the variance, with the ABC score accounting for 8%. For total grey matter volume, the final model accounted for 24% of the variance, with the ABC score accounting for 10%. we provide novel evidence that falls-related self-efficacy, a modifiable risk factor for healthy ageing, is positively associated with total brain volume and total grey matter volume.

    2015-01-01

    The landscape of pharmacy continues to evolve including in Great Britain, where, by 2012, almost 50% of pharmacy contracts were held by just 9 national chains. To further explicate the concept of 'independence' as it was positioned by independent pharmacists, particularly examining personal interpretations of their role in contemporary pharmacy and health care delivery. Research was situated in East and South-east London between 2008 and 2009. The study took an ethnographic approach; combining participant observation within 7 pharmacies and 36 active interviews with pharmacists. Recruitment criteria demanded that pharmacists self-identified as independent and were either owners or managers in sole-owned or independent chain pharmacies. Independence was expressed through a framework of three overarching themes: autonomy, engagement and bespoke practice. Autonomy formed the basis of professional expression ultimately enabling pharmacists to exercise control over customer relationships. This facilitated engagement with communities and individuals and ultimately made possible an offering of a bespoke 'personal' service. The diverse urban environment was a space where independence was seen to be of particular value. The complexity of this setting was used symbolically to support the need for independent thinking. These themes are examined through stories of 'acceptance' and developing pharmacy 'communities' alongside the practise of maintaining personal relationships to provide a distinct service offer. This study highlights distinct 'independent' expression of professional identity and suggests the need to assess the value of independent community pharmacy as being different from but complementary to the service provided by multiples/large chains.

    Nursing staff have an important role in patients' nutritional care. The aim of this study was to demonstrate how the practice of sharing a patient's nutritional status with colleagues was affected by the nursing staff's attitude, knowledge and their priority to provide nutritional care. The participants were 492 nursing staff. We obtained participants' demographic data, the practice of sharing patients' nutritional information and information about participants' knowledge, attitude and priority of providing nutritional care by the questionnaire. We performed partial correlation analyses and linear regression analyses to describe the relationship between the total scores of the practice of sharing patients' nutritional information based on their knowledge, attitude and priority to provide nutritional care. Among the 492 participants, 396 nursing staff (80.5%) completed the questionnaire and were included in analyses. Mean±s.d. of total score of the 396 participants was 8.4±3.1. Nursing staff shared information when they had a high nutritional knowledge (r=0.36, P<0.01) and attitude (r=0.13, P<0.05); however, their correlation coefficients were low. In the linear regression analyses, job categories (β=-0.28, P<0.01), knowledge (β=0.33, P<0.01) and attitude (β=0.10, P<0.05) were independently associated with the practice of sharing information. Nursing staff's priority to provide nutritional care practice was not significantly associated with the practice of sharing information. Knowledge and attitude were independently associated with the practice of sharing patients' nutrition information with colleagues, regardless of their priority to provide nutritional care. An effective approach should be taken to improve the practice of providing nutritional care practice.

    The transition from residency to independent practice presents unique challenges for physicians. New attending physicians often have unmet learning needs in non-clinical domains. An attending physician is an independent medical practitioner, sometimes referred to as a staff physician or consultant. Peer mentorship has been explored as an alternative to traditional mentorship to meet the learning needs of new attendings. In this article, the authors describe how a journal club for general internal medicine fellowship graduates helped ease the transition by facilitating peer mentorship. Journal club members were asked to bring two things to each meeting: a practice-changing journal article, and a 'transition to practice' discussion topic such as a diagnostic dilemma, billing question, or a teaching challenge. Discussions fell into three broad categories that the authors have termed: trading war stories, measuring up, and navigating uncharted waters. It is likely that physicians have a strong need for peer mentorship in the first few years after the transition from residency, and a journal club or similar discussion group may be one way to fulfil this.

    Anaesthetists may fail to recognize and manage certain rare intraoperative events. Simulation has been shown to be an effective educational adjunct to typical operating room-based education to train for these events. It is yet unclear, however, why simulation has any benefit. We hypothesize that learners who are allowed to manage a scenario independently and allowed to fail, thus causing simulated morbidity, will consequently perform better when re-exposed to a similar scenario. Using a randomized, controlled, observer-blinded design, 24 first-year residents were exposed to an oxygen pipeline contamination scenario, either where patient harm occurred (independent group, n=12) or where a simulated attending anaesthetist intervened to prevent harm (supervised group, n=12). Residents were brought back 6 months later and exposed to a different scenario (pipeline contamination) with the same end point. Participants' proper treatment, time to diagnosis, and non-technical skills (measured using the Anaesthetists' Non-Technical Skills Checklist, ANTS) were measured. No participants provided proper treatment in the initial exposure. In the repeat encounter 6 months later, 67% in the independent group vs 17% in the supervised group resumed adequate oxygen delivery (P=0.013). The independent group also had better ANTS scores [median (interquartile range): 42.3 (31.5-53.1) vs 31.3 (21.6-41), P=0.015]. There was no difference in time to treatment if proper management was provided [602 (490-820) vs 610 (420-800) s, P=0.79]. Allowing residents to practise independently in the simulation laboratory, and subsequently, allowing them to fail, can be an important part of simulation-based learning. This is not feasible in real clinical practice but appears to have improved resident performance in this study. The purposeful use of independent practice and its potentially negative outcomes thus sets simulation-based learning apart from traditional operating room learning. © The Author

    Children's eating behavior, food intake, and weight status are highly influenced by parents, who shape their food environment via parental feeding practices. The aim of this study was to investigate associations between sociodemographic, anthropometric, and behavioral/attitudinal characteristics of parents and their 5- to 9-year-old children and a range of positive ("healthy eating guidance," "monitoring") and potentially negative ("restriction for weight control," "restriction for health," "emotion regulation/food as reward," and "pressure") parental feeding practices. Parents completed a questionnaire assessing parental and child characteristics. Parental feeding practices were measured using a Brazilian adaptation of the Comprehensive Feeding Practices Questionnaire. To test associations between parent and child characteristics and parental feeding practices, we ran bivariate logistic regression models with parent and child characteristics as independent variables and high (above median) scores on individual parental feeding practices as outcome variables. We then conducted multivariate logistic regression models containing all parent and child characteristics, controlling for child age and maternal education. Lower parental perceived responsibility for child feeding, higher child use of screen devices, and higher child ultra-processed food intake were associated with lower scores on "healthy eating guidance" and "monitoring." Higher parental perceived responsibility for child feeding and concern about child overweight were associated with higher scores on "restriction for weight control" and "restriction for health." Parental perceptions of low weight and concern about child underweight, and higher perceived responsibility for child feeding, were associated with higher scores on "pressure." Greater intake of ultra-processed foods and lower maternal age were associated with higher scores on "emotion regulation/food as reward." Parental concerns and perceptions

    Background Aging is highly associated with neurodegeneration and atrophy of the brain. Evidence suggests that personality variables are risk factors for reduced brain volume. We examine whether falls-related self-efficacy is independently associated with brain volume. Method A cross-sectional analysis of whether falls-related self-efficacy is independently associated with brain volumes (total, grey, and white matter). Three multivariate regression models were constructed. Covariates included in the models were age, global cognition, systolic blood pressure, functional comorbidity index, and current physical activity level. MRI scans were acquired from 79 community-dwelling senior women aged 65 to 75 years old. Falls-related self-efficacy was assessed by the Activities Specific Balance Confidence (ABC) Scale. Results After accounting for covariates, falls-related self-efficacy was independently associated with both total brain volume and total grey matter volume. The final model for total brain volume accounted for 17% of the variance, with the ABC score accounting for 8%. For total grey matter volume, the final model accounted for 24% of the variance, with the ABC score accounting for 10%. Conclusion We provide novel evidence that falls-related self-efficacy, a modifiable risk factor for healthy aging, is positively associated with total brain volume and total grey matter volume.

  17. Robust discovery of genetic associations incorporating gene-environment interaction and independence.

    This article considers the detection and evaluation of genetic effects incorporating gene-environment interaction and independence. Whereas ordinary logistic regression cannot exploit the assumption of gene-environment independence, the proposed approach makes explicit use of the independence assumption to improve estimation efficiency. This method, which uses both cases and controls, fits a constrained retrospective regression in which the genetic variant plays the role of the response variable, and the disease indicator and the environmental exposure are the independent variables. The regression model constrains the association of the environmental exposure with the genetic variant among the controls to be null, thus explicitly encoding the gene-environment independence assumption, which yields substantial gain in accuracy in the evaluation of genetic effects. The proposed retrospective regression approach has several advantages. It is easy to implement with standard software, and it readily accounts for multiple environmental exposures of a polytomous or of a continuous nature, while easily incorporating extraneous covariates. Unlike the profile likelihood approach of Chatterjee and Carroll (Biometrika. 2005;92:399-418), the proposed method does not require a model for the association of a polytomous or continuous exposure with the disease outcome, and, therefore, it is agnostic to the functional form of such a model and completely robust to its possible misspecification.

    Previous research has indicated that men generally rate slimmer women as more sexually attractive, consistent with the increased morbidity risks associated with even mild abdominal adiposity. To assess the association of women's waist size with a more tangible measure of perceived sexual attractiveness (as well as reward value for both sexes), we examined the association of women's age and waist circumference with an index of men's erectile function (IIEF-5 scores), frequency of penile-vaginal intercourse (PVI), and sexual satisfaction in a representative sample of Czechs (699 men and 715 women) aged 35-65 years. Multivariate analyses indicated that better erectile function scores were independently associated with younger age of self and partner and women's slimmer waist. PVI frequency was independently associated with women's younger age and women's slimmer waist. Sexual satisfaction was independently associated with men's younger age and slimmer waist for both sexes. Better erectile function, greater PVI frequency, and greater sexual satisfaction were associated with women's slimmer waist, independently of both sexes' ages. Possible reasons for the waist effects were discussed, including women's abdominal body fat decreasing their own desire through neurohormonal mechanisms and decreasing their partner's desire through evolutionarily-related decreased sexual attractiveness.

    to verify whether there are associations among occupational roles, independence to perform Activities of Daily Living, purchasing power, and assistive technology for individuals with physical disabilities. 91 individuals with physical disabilities participated in the study. The instruments used were: Role Checklist, Brazilian Economic Classification Criterion, Barthel Index, and a Questionnaire to characterize the subjects. an association with a greater number of roles was found among more independent individuals using a lower number of technological devices. Higher purchasing power was associated with a lower functional status of dependence. even though technology was not directly associated with independence, the latter was associated with a greater number of occupational roles, which requires reflection upon independence issues when considering the participation in occupational roles. These findings support interdisciplinary actions designed to promote occupational roles in individuals with physical disabilities.

    We present a practical technique for using a writer-independent recognition engine to improve the accuracy and speed while reducing the training requirements of a writer-dependent symbol recognizer. Our writer-dependent recognizer uses a set of binary classifiers based on the AdaBoost learning algorithm, one for each possible pairwise symbol comparison. Each classifier consists of a set of weak learners, one of which is based on a writer-independent handwriting recognizer. During online recognition, we also use the n-best list of the writer-independent recognizer to prune the set of possible symbols and thus reduce the number of required binary classifications. In this paper, we describe the geometric and statistical features used in our recognizer and our all-pairs classification algorithm. We also present the results of experiments that quantify the effect incorporating a writer-independent recognition engine into a writer-dependent recognizer has on accuracy, speed, and user training time.

    Recent research has suggested that dietary fructose intake may increase serum uric acid (UA) concentrations. Both UA concentration and fructose consumption maybe also increase in NAFLD. It is not known whether dietary fructose consumption and UA concentration are independently associated with non-alcoholic steatohepatitis (NASH). Our aim was to investigate the factors associated with NASH in children and adolescents with proven NAFLD, and to test whether UA concentrations and fructose consumption are independently associated with NASH. Obese children with NAFLD were studied (n=271). NASH was diagnosed by a NAFLD activity score ⩾5 and the fatty liver inhibition of progression (FLIP) algorithm. Fructose consumption (g/day) was assessed by food frequency questionnaire, and UA (mg/dl) was measured in serum. Binary logistic regression with adjustment for covariates and potential confounders was undertaken to test factors independently associated with NASH. NASH occurred in 37.6% of patients. Hyperuricaemia (UA ⩾5.9mg/dl) was present in 47% of patients with NASH compared with 29.7% of non-NASH patients (p=0.003). Both UA concentration (OR=2.488, 95% CI: 1.87-2.83, p=0.004) and fructose consumption (OR=1.612, 95% CI 1.25-1.86, p=0.001) were independently associated with NASH, after adjustment for multiple (and all) measured confounders. Fructose consumption was independently associated with hyperuricaemia (OR=2.021, 95% CI: 1.66-2.78, p=0.01). These data were confirmed using the FLIP algorithm. Both dietary fructose consumption and serum UA concentrations are independently associated with NASH. Fructose consumption was the only factor independently associated with serum UA concentration. Currently, it is not known whether dietary fructose consumption and uric acid (UA) concentration are linked with non-alcoholic steatohepatitis (NASH) in children and adolescents. Our aim was to test whether UA concentrations and fructose consumption are independently associated with

    Obstructive sleep apnea (OSA) is independently associated with dyslipidemia. Previous studies have demonstrated that sleep fragmentation can impair lipid metabolism. The present study aimed to identify whether sleep fragmentation is independently associated with dyslipidemia, in a large-scale, clinic-based consecutive OSA sample. This cross-sectional study was conducted among 2,686 patients who underwent polysomnography (PSG) for suspicion of OSA from January 2008 to January 2013 at the sleep laboratory. Multivariate regression analyses were performed to evaluate the independent associations between the microarousal index (MAI) and lipid profiles adjusting for potential confounders, including metabolic syndrome components and nocturnal intermittent hypoxia. The adjusted odds ratios (ORs) for various types of dyslipidemia according to MAI quartiles, as determined by logistic regression were also evaluated. MAI was found positively associated with low-density lipoprotein cholesterol (LDL-c) but not with total cholesterol (TC), triglyceride (TG) or high-density lipoprotein cholesterol (HDL-c). Furthermore, the adjusted ORs (95% confidence interval) for hyper-LDL cholesterolemia increased across MAI quartiles, as follows: 1 (reference), 1.3 (1.1-1.7), 1.6 (1.2-2.0), and 1.6 (1.2-2.1) (p = 0.001, linear trend). Sleep fragmentation in OSA is independently associated with hyper-LDL cholesterolemia, which may predispose patients with OSA to a higher risk of cardiovascular disease.

    Stroke-associated pneumonia is a frequent complication after stroke associated with poor outcome. Dysphagia is a known risk factor for stroke-associated pneumonia but accumulating evidence suggests that stroke induces an immunodepressive state increasing susceptibility for stroke-associated pneumonia. We aimed to confirm that stroke-induced immunodepression syndrome is associated with stroke-associated pneumonia independently from dysphagia by investigating the predictive properties of monocytic HLA-DR expression as a marker of immunodepression as well as biomarkers for inflammation (interleukin-6) and infection (lipopolysaccharide-binding protein). This was a prospective, multicenter study with 11 study sites in Germany and Spain, including 486 patients with acute ischemic stroke. Daily screening for stroke-associated pneumonia, dysphagia and biomarkers was performed. Frequency of stroke-associated pneumonia was 5.2%. Dysphagia and decreased monocytic HLA-DR were independent predictors for stroke-associated pneumonia in multivariable regression analysis. Proportion of pneumonia ranged between 0.9% in the higher monocytic HLA-DR quartile (≥21,876 mAb/cell) and 8.5% in the lower quartile (≤12,369 mAb/cell). In the presence of dysphagia, proportion of pneumonia increased to 5.9% and 18.8%, respectively. Patients without dysphagia and normal monocytic HLA-DR expression had no stroke-associated pneumonia risk. We demonstrate that dysphagia and stroke-induced immunodepression syndrome are independent risk factors for stroke-associated pneumonia. Screening for immunodepression and dysphagia might be useful for identifying patients at high risk for stroke-associated pneumonia.

  7. Counterbalancing clinical supervision and independent practice: case studies in learning thoracic epidural catheter insertion.

    PubMed

    Johnson, T

    2010-12-01

    Thoracic epidural catheter placement is an example of a demanding and high-risk clinical skill that junior anaesthetists need to learn by experience and under the supervision of consultants. This learning is known to present challenges that require further study. Ten consultant and 10 trainee anaesthetists in a teaching hospital were interviewed about teaching and learning this skill in the operating theatre, and a phenomenological analysis of their experience was performed. Trainee participation was limited by time pressure, lack of familiarity with consultants, and consultants' own need for clinical experience. There was a particular tension between safe and effective consultant practice and permitting trainees' independence. Three distinct stages of participation and assistance were identified from reports of ideal practice: early (part-task or basic procedure, consultant always present giving instruction and feedback), middle (independent practice with straightforward cases without further instruction), and late (skill extension and transfer). Learning assistance provided by consultants varied, but it was often not matched to the trainees' stages of learning. Negotiation of participation and assistance was recognized as being useful, but it did not happen routinely. There are many obstacles to trainees' participation in thoracic epidural catheter insertion, and learning assistance is not matched to need. A more explicit understanding of stages of learning is required to benefit the learning of this and other advanced clinical skills.

    Early sport practice prevents development of diseases in children/adolescents, but still unclear its effect over health in adulthood. Therefore, the purpose of this study was to analyze the association between sport practice in early life and chronic diseases in adulthood. A retrospective population-based survey carried out in eight Brazilian cities with adults of both genders. Throughout a multistage random process 2720 adults (1096 male and 1624 female) were selected and interviewed. Type 2 diabetes mellitus and arterial hypertension were assessed in a face-to-face interview through a self-report, which was necessarily based on previous medical diagnosis. Early sport practice was assessed in childhood (7-10 years old) and adolescence (11-17 years old). Current physical activity and body mass index were assessed in adulthood throughout a face-to-face interview. Type 2 diabetes mellitus and arterial hypertension were identified in 8.1% (95% CI, 7.1-9.2) and 23.5% (95% CI, 21.9-25.1) of the sample, respectively. Early sport practice during childhood and adolescence was associated with lower occurrence of arterial hypertension (OR, 0.49; 95% CI, 0.33-0.73) and type 2 diabetes (OR, 0.46; 95% CI, 0.24-0.88) in adulthood. Independently of obesity and current physical activity, early sport practice in early life was positively associated with lower occurrence of chronic diseases in adulthood.

    Retrieval-induced forgetting (RIF) is the finding of impaired memory performance for information stored in long-term memory due to retrieval of a related set of information. This phenomenon is often assigned to operations of a specialized mechanism recruited to resolve interference during retrieval by deactivating competing memory representations. This inhibitory account is supported by, among others, findings showing that RIF occurs with independent cues not used during retrieval practice. However, these findings are not always consistent. Recently, Norman, Newman, and Detre (2007) have proposed a model that aims at resolving discrepancies concerning cue-independence of RIF. The model predicts that RIF should be present with independent cues when episodic associations are created between independent cues and their targets in the same episodic context that is later used to cue memory during retrieval practice. In the present study we aimed to test this prediction. We associated studied items with semantically unrelated words during the main study phase of the retrieval practice paradigm, and we tested memory with both cues used during retrieval practice (Experiment 2) and episodic associates serving as independent cues (Experiments 3a and 3b). Although RIF was present when the same cues were used during retrieval practice and a final test, contrary to the prediction formulated by Norman et al., RIF failed to emerge when episodic associates were employed as independent cues.

    The relatively low key rate seems to be the major barrier to its practical use for the decoy-state measurement-device-independent quantum key distribution (MDI-QKD). We present a four-intensity protocol for the decoy-state MDI-QKD that hugely raises the key rate, especially in the case in which the total data size is not large. Also, calculations show that our method makes it possible for secure private communication with fresh keys generated from MDI-QKD with a delay time of only a few seconds.

    This study evaluated characteristics of applicants selected for interview and ranked by independent general surgery residency programs and assessed independent program application volumes, interview selection, rank list formation, and match success. Demographic and academic information was analyzed for 2014-2015 applicants. Applicant characteristics were compared by ranking status using univariate and multivariable statistical techniques. Characteristics independently associated with whether or not an applicant was ranked were identified using multivariable logistic regression modeling with backward stepwise variable selection and cluster-correlated robust variance estimates to account for correlations among individuals who applied to multiple programs. The Electronic Residency Application Service was used to obtain applicant data and program match outcomes at 33 independent surgery programs. All applicants selected to interview at 33 participating independent general surgery residency programs were included in the study. Applicants were 60% male with median age of 26 years. Birthplace was well distributed. Most applicants (73%) had ≥1 academic publication. Median United States Medical Licensing Exams (USMLE) Step 1 score was 228 (interquartile range: 218-240), and median USMLE Step 2 clinical knowledge score was 241 (interquartile range: 231-250). Residency programs in some regions more often ranked applicants who attended medical school within the same region. On multivariable analysis, significant predictors of ranking by an independent residency program were: USMLE scores, medical school region, and birth region. Independent programs received an average of 764 applications (range: 307-1704). On average, 12% interviews, and 81% of interviewed applicants were ranked. Most programs (84%) matched at least 1 applicant ranked in their top 10. Participating independent programs attract a large volume of applicants and have high standards in the selection process

  12. Feedback increases benefits but not costs of retrieval practice: Retrieval-induced forgetting is strength independent.

    PubMed

    Tempel, Tobias; Frings, Christian

    2018-04-01

    We examined how the provision of feedback affected two separate effects of retrieval practice: strengthening of practiced information and forgetting of related, unpracticed information. Feedback substantially increased recall of retrieval-practiced items. This unsurprising result shows once again that restudy opportunities boost the benefits of testing. In contrast, retrieval-induced forgetting was unaffected by the manipulation and occurred in equal size with or without feedback. These findings demonstrate strength independence of retrieval-induced forgetting and thus support a theoretical account assuming that an inhibitory mechanism causes retrieval-induced forgetting. According to this theory, inhibition resolves competition that arises during retrieval attempts but is unrelated to the consequences of retrieval practice concerning practiced items. The present results match these assumptions and contradict the theoretical alternative that blocking by strengthened information might explain retrieval-induced forgetting. We discuss our findings against the background of previous studies.

    A trend towards increasingly new forms of dental practice has been observed in the FDI World Dental Federation. Elementary foundations such as the free dentist and therapy choice, and independent, free, self-responsible professional practice may be undermined. The current study is aimed at analyzing the general training framework, organization, and professional types of dental practice in the European Regional Organization (ERO) zone and at critically discussing selected aspects of changes in the dental profession. A questionnaire was developed by the ERO Working-Group "Liberal Dental Practice." Information about dental schools, professional organizations, dental practice regulations, and ambulatory healthcare centers was analyzed. Self-employed dental practice is the most common type of practice (51.7%). Dentists are allowed to work independently immediately after graduation (72.7%). Approximately one-third are organized as compulsory members in chambers/corporations. The density of dentists has a mean of 1,570 inhabitants per dentist. In most countries, there are no special rules for founding dental ambulatory healthcare centers. In a total of 353 universities of the ERO countries surveyed, 16,619 dentists per year were trained, with a trend toward a higher percentage of female students (63%). Despite modern forms of dental practice, the charter of the individual liberal dental profession (CED et al, 2013) should be respected and taken into account on the basis of ethical principles. The commercialization of the dental profession can be neutralized only by establishing and following well-defined ethical principles; oral healthcare quality can thus be ensured without the influence of third parties.

    The validity of medical student projection of, and predictors for, rural practice and the association of a measure of service orientation, projected practice accessibility to the indigent, were investigated. West Virginia (WV) medical student online pre- and postrural rotation questionnaire data were collected during the time period 2001-2009. Of the 1,517 respondent students, submissions by 1,271 met the time interval criterion for inclusion in analyses. Subsequent WV licensing data were available for 461 in 2013. These 2 databases were used to assess for validity of projection of rural practice, for predictors of rural practice, and for student projected accessibility of the future practice to indigent patients. There were statistically significant associations between both pre- and postrotation projections of rural practice and subsequent rural practice. The most significant independent predictors of rural practice were student rural background, reported primary care intent, prediction of rural practice and projection of greater accessibility of the future practice to indigent patients. For scoring of practice access, there were trends for higher scoring by rural students and rural practitioners, with greater pre-post increases for those with urban hometowns. This study demonstrates the utility of medical student questionnaires for projections of numbers of future rural physicians.

It also suggests that students, particularly those with urban hometowns, are influenced by rural rotation experiences in forecasting greater practice accessibility and in entering rural practice. © 2015 National Rural Health Association.

    Epidemiological evidence strongly suggests that fruit consumption promotes many health benefits. Despite the general consensus that fruit and juice are nutritionally similar, epidemiological results for juice consumption are conflicting. Our objective was to use DNA methylation marks to characterize fruit and juice epigenetic signatures within PBMCs and identify shared and independent signatures associated with these groups. Genome-wide DNA methylation marks (Illumina Human Methylation 450k chip) for 2,148 individuals that participated in the Framingham Offspring exam 8 were analyzed for correlations between fruit or juice consumption using standard linear regression. CpG sites with low P -values ( P < 0.01) were characterized using Gene Set Enrichment Analysis (GSEA), Ingenuity Pathway Analysis (IPA), and epigenetic Functional element Overlap analysis of the Results of Genome Wide Association Study Experiments (eFORGE). Fruit and juice-specific low P -value epigenetic signatures were largely independent. Genes near the fruit-specific epigenetic signature were enriched among pathways associated with antigen presentation and chromosome or telomere maintenance, while the juice-specific epigenetic signature was enriched for proinflammatory pathways. IPA and eFORGE analyses implicate fruit and juice-specific epigenetic signatures in the modulation of macrophage (fruit) and B or T cell (juice) activities. These data suggest a role for epigenetic regulation in fruit and juice-specific health benefits and demonstrate independent associations with distinct immune functions and cell types, suggesting that these groups may not confer the same health benefits. Identification of such differences between foods is the first step toward personalized nutrition and ultimately the improvement of human health and longevity.

    Obesity and fitness have been associated with older adults' physical independence. We aimed to investigate the independent and combined associations of physical fitness and adiposity, assessed by body mass index (BMI) and waist circumference (WC) with the projected ability for physical independence. A total of 3496 non-institutionalized older adults aged 65 and older (1167 male) were included in the analysis. BMI and WC were assessed and categorized according to established criteria. Physical fitness was evaluated with the Senior Fitness Test and individual test results were expressed as Z-scores. Projected ability for physical independence was assessed with the 12-item composite physical function scale. Logistic regression was used to estimate the odds ratio (OR) for being physically dependent. A total of 30.1 % of participants were classified as at risk for losing physical independence at age 90 years. Combined fitness and fatness analysis demonstrated that unfit older adults had increased odds ratio for being physically dependent in all BMI categories (normal: OR = 9.5, 95 %CI = 6.5-13.8; overweight: OR = 6.0, 95 %CI = 4.3-8.3; obese: OR = 6.7, 95 %CI = 4.6-10.0) and all WC categories (normal: OR = 10.4, 95%CI = 6.5-16.8; middle: OR = 6.2, 95 %CI = 4.1-9.3; upper: OR = 7.0, 95 %CI = 4.8-10.0) compared to fit participants that were of normal weight and fit participants with normal WC, respectively. No increased odds ratio was observed for fit participants that had increased BMI or WC. In conclusion, projected physical independence may be enhanced by a normal weight, a normal WC, or an increased physical fitness. Adiposity measures were not associated with physical independence, whereas fitness is independently related to physical independence. Independent of their weight and WC status, unfit older adults are at increased risk for losing physical independence.

  18. Practical device-independent quantum cryptography via entropy accumulation.

    Device-independent cryptography goes beyond conventional quantum cryptography by providing security that holds independently of the quality of the underlying physical devices. Device-independent protocols are based on the quantum phenomena of non-locality and the violation of Bell inequalities. This high level of security could so far only be established under conditions which are not achievable experimentally. Here we present a property of entropy, termed "entropy accumulation", which asserts that the total amount of entropy of a large system is the sum of its parts. We use this property to prove the security of cryptographic protocols, including device-independent quantum key distribution, while achieving essentially optimal parameters. Recent experimental progress, which enabled loophole-free Bell tests, suggests that the achieved parameters are technologically accessible. Our work hence provides the theoretical groundwork for experimental demonstrations of device-independent cryptography.

    OBJECTIVE To examine whether chronotype and daily caloric distribution are associated with glycemic control in patients with type 2 diabetes independently of sleep disturbances. RESEARCH DESIGN AND METHODS Patients with type 2 diabetes had a structured interview and completed questionnaires to collect information on diabetes history and habitual sleep duration, quality, and timing. Shift workers were excluded. A recently validated construct derived from mid-sleep time on weekends was used as an indicator of chronotype. One-day food recall was used to compute the temporal distribution of caloric intake. Hierarchical linear regression analyses controlling for demographic and sleep variables were computed to determine whether chronotype was associated with HbA1c values and whether this association was mediated by a higher proportion of caloric intake at dinner. RESULTS We analyzed 194 completed questionnaires. Multiple regression analyses adjusting for age, sex, race, BMI, insulin use, depressed mood, diabetes complications, and perceived sleep debt found that chronotype was significantly associated with glycemic control (P = 0.001). This association was partially mediated by a greater percentage of total daily calories consumed at dinner. CONCLUSIONS Later chronotype and larger dinner were associated with poorer glycemic control in patients with type 2 diabetes independently of sleep disturbances. These results suggest that chronotype may be predictive of disease outcomes and lend further support to the role of the circadian system in metabolic regulation. PMID:23637357

    The health benefits of exclusive breastfeeding are well-known, but the relative detrimental impacts of other foods on infant health are unknown. Because infants in developing countries are fed a wide range of food, quantifying the burden of these diverse feeding practices on infant health is essential for public health policy. We used data from the Demographic Health Survey from 20 developing countries over multiple years to examine the independent association of six different types of food (exclusive breastfeeding, non-exclusive breastfeeding, infant formula, milk liquids, non-milk liquids, and solid foods) with five measures of infant health (length, weight, diarrhea, fever, and cough). We estimated associations with regression analysis, controlling for confounding factors with infant, mother, and household factors and community-year fixed effects. We used these estimates in a simulation model to quantify the burden of different combinations of food on infant health. We show that for an infant younger than 6 months old, following current guidelines and exclusively breastfeeding instead of giving the infant solid foods may increase length by 0.75 cm and weight by 0.25 kg and decrease diarrhea, fever, and cough prevalence by 8, 12, and 11%, respectively. We found that the burden on infant health of some feeding practices is less than others. Although all other feeding practices are associated with worse health outcomes than exclusive breastfeeding, breastfeeding supplemented with liquids has a lower burden on infant health than solid foods and infant formula has a lower burden than milk or non-milk liquids as measured by four of five health metrics. Providing specific quantified burden estimates of these practices can help inform public health policy related to infant feeding practices. PMID:24400267

    Recent studies have demonstrated that physical activity (PA) and cardiorespiratory fitness (CRF) are independent predictors of stroke in men. The combined associations of these 2 factors are not well established. To investigate the independent and joint associations of PA and CRF with fatal, nonfatal, and total stroke in a group of men. The current analyses included 45 689 men aged 18 to 100 years who completed baseline sessions between 1970 and 2001. All participants had no known myocardial infarction, stroke, or cancer. Physical activity was measured by questionnaire, and CRF was assessed from a maximal treadmill exercise test. The National Death Index for fatal stroke and mail-back surveys for nonfatal stroke were used to ascertain cases. Cox regression analyses were used to estimate the risk of stroke outcomes. There were 619 cases over 800 582 person-years of observation. Significant inverse associations were observed between CRF and fatal, nonfatal, and total strokes after adjustment for age and examination year (P for trend < 0.05 for each). No associations were found between PA and any of the 3 outcomes after adjusting for other covariates and CRF. Joint associations of 9 PA fitness groups showed less risk for total stroke in the moderate and high fitness categories. These findings suggest that CRF is an independent predictor of incident stroke in asymptomatic men.

    Background Inappropriate storage of fatty acids as triglycerides in adipocytes and their removal from adipocytes through lipolysis and subsequent oxidation may cause the atherogenic dyslipidemia phenotype of elevated apolipoprotein B levels and subsequent hypertriglyceridemia. We tested whether turnover of triglycerides in fat cells was related to dyslipidemia. Methods and Results The age of triglycerides (reflecting removal) and triglyceride storage in adipocytes was determined under free living conditions by measuring incorporation of atmospheric 14C into these lipids within the adipocytes in 47 women and 26 men with a large interindividual variability in body mass index. Because limited 14C data were available, triglyceride age was also determined in 97 men and 233 women by using an algorithm based on adipocyte lipolysis, body fat content, waist‐to‐hip ratio, and insulin sensitivity. This cohort consisted of nonobese subjects since obesity per se is related to all components in the algorithm. Triglyceride turnover (age and storage) was compared with plasma levels of apolipoproteins and lipids. Plasma levels of apolipoprotein B and triglycerides were positively related to triglyceride age in adipocytes, when measured directly using radiocarbon analyses (r=0.45 to 0.47; P<0.0001). This effect was independent of subject age, waist circumference measures, and insulin sensitivity (partial r=0.29 to 0.45; P from 0.03 to <0.0001). Triglyceride storage showed no independent correlation (partial r=0.02 to 0.11; P=0.42 to 0.91). Algorithm‐based values for adipocyte removal of triglycerides were positively associated with plasma triglycerides and apolipoprotein B (r=0.44 to 0.45; P<0.0001) and (also positively) with the inflammation status of adipose tissue (r=0.39 to 0.47; P<0.05). These correlations were statistically independent of subject age and observed in men and women as well as in lean and overweight subjects when subgroups were examined separately

    Objective The purpose of this study was to determine the lifestyle and lifestyle-related comorbidities independently associated with colorectal adenoma (CRA) recurrence in elderly Chinese people. Methods During the 5-year follow-up after the initial colonoscopy, participants aged >60 years with the diagnosis and removal of CRA underwent a complete surveillance colonoscopy, and 152 participants with CRA recurrence plus 152 participants free of recurrence were included in this analysis. Results Participants with CRA recurrence were more likely to consume less vegetables and fruits, and more red meats compared with the control group (P<0.05 for all). Lifestyle-related comorbidities, including hypertension and nonalcoholic fatty liver disease (NAFLD), were more common in participants with CRA recurrence than in the control group (P<0.05 for all). In the multivariate analysis, pack-years of smoking were independently associated with an increased CRA recurrence (odds ratio [OR]: 1.03; P<0.05). Eating less vegetables (OR: 099; P<0.05) and fruits (OR: 0.98; P<0.05) was identified as a statistically independent factor influencing CRA recurrence, as was eating more red meats (OR: 1.01; P<0.05). Hypertension was also found to be a factor independently associated with an increased CRA recurrence (OR: 2.44; P<0.05). NAFLD had an independent association, with an increased CRA recurrence (OR: 3.43; P<0.05). Conclusion Smoking cigarettes, high consumption of red meats, low intake of fruits and vegetables, and the presence of hypertension and NAFLD were independently associated with an increased CRA recurrence in elderly Chinese people. This conclusion helps elderly Chinese people to make effective behavioral changes, such as smoking cessation, substitution of fruits and vegetables for red meats, and timely treatment of hypertension and NAFLD, to reduce CRA recurrence and colorectal cancer risk.

    Muscle density is a risk factor for fractures in older adults; however, its association with falls is not well described. After adjusting for biologically relevant confounding factors, a unit decrease in muscle density was associated with a 17 % increase in odds of reporting a fall, independent of functional mobility. Falls are the leading cause of injury, disability, and fractures in older adults. Low muscle density (i.e., caused by muscle adiposity) and functional mobility have been identified as risk factors for incident disability and fractures in older adults; however, it is not known if these are also independently associated with falls. The purpose of this study was to explore the associations of muscle density and functional mobility with fall status. Cross-sectional observational study of 183 men and women aged 60-98 years. Descriptive data, including a 12-month fall recall, Timed Up and Go (TUG) test performance, lower leg muscle area, and density. Odds ratio (OR) of being a faller were calculated, adjusted for age, sex, body mass index, general health status, diabetes, and comorbidities. Every mg/cm(3) increase in muscle density (mean 70.2, SD 2.6 mg/cm(3)) independently reduced the odds of being a faller by 19 % (OR 0.81 [95 % CI 0.67 to 0.97]), and every 1 s longer TUG test time (mean 9.8, SD 2.6 s) independently increased the odds by 17 % (OR 1.17 [95 % CI 1.01 to 1.37]). When both muscle density and TUG test time were included in the same model, only age (OR 0.93 [95 % CI 0.87 to 0.99]) and muscle density (OR 0.83 [95 % CI 0.69 to 0.99]) were independently associated with fall status. Muscle density was associated with fall status, independent of functional mobility. Muscle density may compliment functional mobility tests as a biometric outcome for assessing fall risk in well-functioning older adults.

    To examine associations of self-reported arthritis in 25 urban and rural family practice clinics with education (individual socioeconomic status) and community poverty (community socioeconomic status). A total of 7,770 patients at 25 family practice sites across North Carolina self-reported whether they had arthritis. Education was measured as less than a high school (HS) degree, a HS degree, and more than a HS degree. The US Census 2000 block group poverty rate (percentage of households in poverty in that block group) was grouped into low, middle, and high tertiles. We assumed heterogeneity by race (non-Hispanic white and African American) for the effects of these sociodemographic variables, and therefore stratified by race. Multilevel analyses were performed using a 2-level mixed logistic model to examine the independent associations and joint effects of education and poverty with self-reported arthritis as the outcome, adjusting for age, sex, and body mass index. White participants with less than a HS degree living in block groups with high poverty had 1.55 times the odds (95% confidence interval [95% CI] 1.10-2.17) of reporting arthritis compared with white participants with more than a HS degree and low poverty rates. African American participants with less than a HS degree and high poverty rates had 2.06 times the odds (95% CI 1.16-3.66) of reporting arthritis compared with African American participants with more than a HS degree and low poverty rates. In the family practice setting, both disadvantaged white and African American participants showed increased odds of self-reported arthritis, with stronger associations in African Americans.

    Dog ownership is positively associated with children's physical activity. It is plausible that dog-facilitated activity rather than dog ownership per se encourages children's physical activity behaviors. We examined relationships between dog walking and children's physical activity, and outdoor play and independent mobility. Cross-sectional survey data from the 2007 Perth (Western Australia) TRavel, Environment, and Kids (TREK) project were analyzed for 727 10-12 year olds with a family dog. Weekly minutes of overall physical activity and walking, local walking and outdoor play were collected from children and parents. Children's weekly pedometer steps were measured. Independent mobility was determined by active independent travel to 15 local destinations. Overall, 55% of children walked their dog. After adjustment, more dog walkers than non-dog walkers walked in the neighborhood (75% vs. 47%), played in the street (60% vs. 45%) and played in the yard (91% vs. 84%) (all p ≤ 0.05). Dog walkers were more independently mobile than non-dog walkers (p ≤ 0.001). Dog walking status was not associated with overall physical activity, walking, or pedometer steps (p>0.05). Dog-facilitated play and physical activity can be an effective strategy for increasing children's physical activity. Dog walking may provide a readily accessible and safe option for improving levels of independent mobility. Copyright © 2014 Elsevier Inc. All rights reserved.

    To assess factors associated with infant feeding practices on the first day at home after hospital discharge. A total of 209 women, who had a child aged four months or less and were living in Itapira, Brazil, were interviewed during the National Immunization Campaign Day in 1999. Statistical analysis was performed using the Chi-square test and a logistic regression model was used for verifying an association between dependent and independent variables. Women aged 25.5 years on average and 18.2% were teenagers. Fifty-three percent of the women delivered vaginally and most vaginal deliveries (78.5%) took place in the public hospital. The prevalence of exclusive breastfeeding on the first day at home was 78.1% and 11.6% of the infants were receiving formula at this time. The only factor associated with EBF on the first day at home was being a teenaged-primiparous mother (OR=9.40; 95% CI: 1.24-71.27). This association remained statistically significant even after controlling for type of delivery and hospital where the birth took place. Feeding formula on the first day at home was only significantly associated with the hospital (i.e., birth at the city hospital was a protective factor (OR=0.33; 95% CI: 0.13-0.86), even after controlling for vaginal delivery. On the first day at home after hospital discharge, teenaged-primiparous mothers were more likely to exclusive breastfeeding as well as those infants born in the municipal public hospital. Further studies are needed from a multidisciplinary approach.

    Study Objective: We aimed to evaluate the association between sleep quality and physical disability in community-dwelling older adults. Methods: There were 213 community-dwelling adults (76 men and 137 women) aged 65 years and above participated into this investigation. The Groningen Activity Restriction Scale and the Pittsburgh Sleep Quality Index were utilized to evaluate physical disability and subjective sleep quality, respectively. Global functional capacity was measured by the 6-minute walk test (6MWT). The Mini Mental State Examination and the Chinese Geriatric Depression Screening Scale were used to evaluate cognitive function and depression. Results: Univariate analysis revealed a correlation between physical disability and poor sleep quality, older age, 2 or more comorbidities, depression, functional capacity, and poor cognitive function. However, in the multivariate analyses, depression failed to show significant association with physical disability. In contrast, an independent association was observed between poor sleep quality and physical disability (OR = 2.03; 95% CI: 1.02–4.05). Conclusions: In community-dwelling older adults, subjective poor sleep was significantly associated with physical disability, even after controlling for the effects of other established risk factors.

    Diarrhoea is a major cause of childhood morbidity and mortality globally. While the childhood diarrhoea and its association with child feeding, and hygiene, hand washing and water treatment are studied elsewhere, the association of water handling and child feeding with childhood diarrhoea is an understudied area in Nepal. This study aimed to investigate the association of water handling and child feeding practice with childhood diarrhoea among children of one to five years of age in Southern, Nepal. A cross-sectional study was conducted in the Dhanusha district of Southern Nepal in 2013. A total of 284 mother-child pairs were selected using systemic random sampling. A four-week prevalence of childhood diarrhoea was reported using frequency distribution. The association of childhood diarrhoea with water handling and child feeding practices was ascertained using multiple logistic regressions after adjusting for potential confounders. The result of the study demonstrated that the four-week prevalence of childhood diarrhoea was 36.6%. Our finding showed that unsafe water handling practices were associated independently with childhood diarrhoea: untreated water (aOR 3.55; 95% CI: 1.13-11.10), uncovered water (aOR 2.14; 95% CI: 1.09-4.19). Similarly, partial breast feeding (aOR 4.35; 95% CI: 1.87-10.12) was also associated with higher odds of childhood diarrhoea. One third of children in Southern Nepal still had diarrhoea within the four weeks preceding the survey. As poor water handling and sub optimal infant feeding practice were major risk factors contributing to such a high burden of the disease, health promotion strategies such as promotion of safe water handling, improved hygiene and child feeding practices are recommended for the prevention of childhood diarrhoea in Southern Terai of Nepal.

    SUMMARY This study examines the independent effects of neighbourhood context (i.e. neighbourhood poverty) and exposure to perceived discrimination in shaping risk of obesity over time. Weighted 3-level hierarchical linear regression models for a continuous outcome were used to assess independent effects of neighbourhood poverty and perceived discrimination on obesity over time in a sample of 157 Non-Hispanic Black, Non-Hispanic White, and Hispanic adults 2002/2003 and 2007/2008. Independent associations were found between neighbourhood poverty and perceived discrimination with central adiposity over time. Residents of neighbourhoods with high concentrations of poverty were more likely to show increases in central adiposity compared to those in neighbourhoods with lower concentrations of poverty. In models adjusted for BMI, neighbourhood poverty at baseline was associated with greater change in central adiposity among participants who lived in neighbourhoods in the second (B=3.79, P=0.025) and third (B=3.73, P=0.024) quartiles, compared with those in the lowest poverty neighbourhoods. Results from models that included both neighbourhood poverty and perceived discrimination showed that both neighbourhood poverty and discrimination were associated with increased risk of increased central adiposity over time. Residents of neighbourhoods in the second (B=9.58, P<0.001), third (B=8.25, P=0.004), and fourth (B=7.66, P=0.030) quartiles of poverty remained more likely to show greater increases in central adiposity over time, compared with those in the lowest poverty quartile, mean discrimination at baseline independently and positively associated with increases in central adiposity over time (B= 2.36, P=0.020). These results suggest that neighbourhood poverty and perceived discrimination are independently associated with heightened risk of increases in central adiposity over time. Efforts to address persistent disparities in the central adiposity in the USA should include

    2015-01-01

    This study examined whether five specific parenting practices (i.e., monitoring, discipline, skill encouragement, problem solving, and positive involvement) were associated with reduced child externalizing behaviors among a sample of Latino immigrant families. It utilized baseline data from 83 Latino couples with children participating in a larger randomized controlled trial of a culturally adapted parenting intervention. Results reveal that monitoring, discipline, skill encouragement, and problem solving each made independent contributions to the prediction of child externalizing behavior, although not all in the expected direction.

    This study examined whether five specific parenting practices (i.e., monitoring, discipline, skill encouragement, problem solving, and positive involvement) were associated with reduced child externalizing behaviors among a sample of Latino immigrant families. It utilized baseline data from 83 Latino couples with children participating in a larger randomized controlled trial of a culturally adapted parenting intervention. Results reveal that monitoring, discipline, skill encouragement, and problem solving each made independent contributions to the prediction of child externalizing behavior, although not all in the expected direction.

    Existing research demonstrates superior short-term outcomes (length of stay, 1-year survival) after lung transplantation in patients with preoperative functional independence. The aim of this study was to determine whether advantages remain significant in the long-term. The United Network for Organ Sharing database was queried for adult, first-time, isolated lung transplantation records from January 2005 to December 2015. Stratification was performed based on Karnofsky Performance Status Score (3 groups) and on employment at the time of transplantation (2 groups). Kaplan-Meier and Cox analyses were performed to determine the association between these factors and survival in the long-term. Of 16,497 patients meeting criteria, 1,581 (9.6%) were almost completely independent at the time of transplant vs 5,662 (34.3%) who were disabled (completely reliant on others for activities of daily living). Cox models adjusting for recipient, donor, and transplant factors demonstrated a statistically significant association between disability at the time of transplant and long-term death (hazard ratio, 1.26; 95% confidence interval, 1.14 to 1.40; p < 0.001). There were 15,931 patients with available data on paid employment at the time of transplantation. Multivariable analysis demonstrated a statistically significant association between employment at the time of transplantation and death (hazard ratio, 0.86; 95% confidence interval, 0.75 to 0.91; p < 0.001). Preoperative functional independence and maintenance of employment are associated with superior long-term outcomes in lung recipients. The results highlight potential benefits of pretransplant functional rehabilitation for patients on the waiting list for lungs. Copyright © 2018 The Society of Thoracic Surgeons.

    Inpatient falls are associated with significant morbidity and increased healthcare costs. Zolpidem has been reported to decrease balance and is associated with falls. Yet, it is a commonly used hypnotic agent in the inpatient setting. Zolpidem use in hospitalized patients may be a significant and potentially modifiable risk factor for falling. To determine whether inpatients administered zolpidem are at greater risk of falling. Retrospective cohort study. Adult non-intensive care unit (non-ICU) inpatients at a tertiary care center. Adult inpatients who were prescribed zolpidem were identified. Electronic medical records were reviewed to capture demographics and other risk factors for falls. The fall rate was compared in those administered zolpidem versus those only prescribed zolpidem. Multivariate analyses were performed to determine whether zolpidem was independently associated with falls. The fall rate among patients who were prescribed and received zolpidem (n = 4962) was significantly greater than among patients who were prescribed but did not receive zolpidem (n = 11,358) (3.04% vs 0.71%; P < 0.001). Zolpidem use continued to remain significantly associated with increased fall risk after accounting for age, gender, insomnia, delirium status, dose of zolpidem, Charlson comorbidity index, Hendrich's fall risk score, length of hospital stay, presence of visual impairment, gait abnormalities, and dementia/cognitive impairment (adjusted odds ratio [OR] 4.37, 95% confidence interval [CI] = 3.34-5.76; P < 0.001). Additionally, patients taking zolpidem who experienced a fall did not differ from other hospitalized adult patients who fell in terms of age, opioids, antidepressants, sedative-antidepressants, antipsychotics, benzodiazepine, or antihistamine use. Zolpidem use was a strong, independent, and potentially modifiable risk factor for inpatient falls. Copyright © 2012 Society of Hospital Medicine.

    To examine whether there is a difference in the likelihood that a general dentist practices in a rural location based on individual characteristics, including dental school attended, birth state, practice arrangement, sex, and age. All private practice, general dentists in Iowa were included in this study. Data were extracted from the year 2010 version of the Iowa Dentist Tracking System, which monitors practice patterns of active dentists. Rurality of primary office location, categorized using Rural-Urban Commuting Area codes, served as the outcome variable. Chi-square tests and multivariable logistic regression were used to explain associations between rural practice location and dentist characteristics. Fifteen percent of the state's population resided in isolated small rural towns, but only 8% of general dentists practiced here. Approximately 17% of dentists in isolated small rural towns were age 40 or younger, compared to 32% of dentists in urban areas. Among male dentists, those who were born in Iowa (P = .002) were older (P = .020), and graduated from dental schools other than the University of Iowa (P = .009) were more likely to practice in rural areas than were their counterparts. Conversely, among female dentists, solo practice (P = .016) was the only variable significantly associated with rural practice location. The dentist workforce in rural areas of Iowa is dominated by older males who were born in Iowa. As this generation retires and increasing numbers of women enter the profession, state policy makers and planners will need to monitor changing trends in the rural workforce. © 2013 National Rural Health Association.

  20. Increased dietary sodium is independently associated with greater mortality among prevalent hemodialysis patients.

    2012-07-01

    Dietary sodium is thought to play a major role in the pathogenesis of hypertension, hypervolemia, and mortality in hemodialysis patients; hence, sodium restriction is almost universally recommended. Since the evidence upon which to base these assumptions is limited, we undertook a post-hoc analysis of 1770 patients in the Hemodialysis Study with available dietary, clinical, and laboratory information. Within this cohort, 772 were men, 1113 black, and 786 diabetic, with a mean age of 58 years and a median dietary sodium intake of 2080 mg/day. After case-mix adjustment, linear regression modeling found that higher dietary sodium was associated with a greater ultrafiltration requirement, caloric and protein intake; sodium to calorie intake ratio was associated with a greater ultrafiltration requirement; and sodium to potassium ratio was associated with higher serum sodium. No indices were associated with the pre-dialysis systolic blood pressure. Cox regression modeling found that higher baseline dietary sodium and the ratio of sodium to calorie or potassium were each independently associated with greater all-cause mortality. No association between a prescribed dietary sodium restriction and mortality were found. Thus, higher reported dietary sodium intake is independently associated with greater mortality among prevalent hemodialysis patients. Randomized trials will be necessary to determine whether dietary sodium restriction improves survival.

    To determine whether associations of calf muscle density with physical function are independent of other determinants of functional decline in overweight and obese older adults. This was a secondary analysis of a cross-sectional study of 85 community-dwelling overweight and obese adults (mean±SD age 62.8±7.9 years; BMI 32.3±6.1 kg/m2; 58% women). Peripheral quantitative computed tomography assessed mid-calf muscle density (66% tibial length) and dual-energy X-ray absorptiometry determined visceral fat area. Fasting glucose, Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) and C-reactive protein (CRP) were analysed. Physical function assessments included hand grip and knee extension strength, balance path length (computerised posturography), stair climb test, Short Physical Performance Battery (SPPB) and self-reported falls efficacy (Modified Falls Efficacy Scale; M-FES). Visceral fat area, not muscle density, was independently associated with CRP and fasting glucose (B=0.025; 95% CI 0.009-0.042 and B=0.009; 0.001-0.017, respectively). Nevertheless, higher muscle density was independently associated with lower path length and stair climb time, and higher SPPB and M-FES scores (all P⟨0.05). Visceral fat area, fasting glucose and CRP did not mediate these associations. Higher calf muscle density predicts better physical function in overweight and obese older adults independent of insulin resistance, visceral adiposity or inflammation.

    Measurement-device-independent quantum key distribution (MDI-QKD) is immune to all detector side-channel attacks. However, practical implementations of MDI-QKD, which require two-photon interferences from separated independent single-photon sources and a nontrivial reference alignment procedure, are still challenging with current technologies. Here, we propose a scheme that significantly reduces the experimental complexity of two-photon interferences and eliminates reference frame alignment by the combination of plug-and-play and reference frame independent MDI-QKD. Simulation results show that the secure communication distance can be up to 219 km in the finite-data case and the scheme has good potential for practical MDI-QKD systems.

    Esophageal motor disorder (EMD) has been shown to be associated with gastroesophageal reflux disease (GERD). However, the association of EMD with a Barrett's esophagus (BE) is controversial. Our objective was to evaluate whether the presence of EMD was an independent factor associated with BE. A retrospective case-control study was conducted in GERD patients who all had oeso-gastroduodenal endoscopy and high-resolution esophageal manometry. The clinical data collected was known or potential risk factors for BE: male gender, smoking and alcohol consumption, age, body mass index, presence of hiatal hernia, frequency, and age of GERD. EMD were classified according to the Chicago classification into: ineffective motor syndrome, fragmented peristalsis and absence of peristalsis, lower esophageal sphincter hypotonia. Two hundred and one patients (101 in the GERD + BE group and 100 in the GERD without BE) were included. In univariate analysis, male gender, alcohol consumption, presence of hiatal hernia, and EMD appeared to be associated with the presence of BE. In a multivariate analysis, 3 independent factors were identified: the presence of EMD (odds ratio [OR], 3.99; 95% confidence interval [CI], 1.71-9.28; P = 0.001), the presence of hiatal hernia (OR, 5.60; 95% CI, 2.45-12.76; P < 0.001), Helicobacter pylori infection (OR, 0.08; 95% CI, 0.01-0.84; P = 0.035). The presence of EMD (particularly ineffective motor syndrome and lower esophageal sphincter hypotonia) is a strong independent associated factor of BE. Searching systematically for an EMD in patients suffering from GERD could be a new strategy to organize the endoscopic follow-up.

    Leadership is a process by which an individual influences a group or individual to achieve a common goal, in this case health promotion for individuals with disabilities. (1) To examine the association between the transformational leadership behaviors of the Association of University Centers on Disabilities (AUCD) network professionals and their practice beliefs about health promotion activities, specifically cardiovascular fitness and healthy weight, for people with disabilities. (2) To determine if discipline and/or years of practice moderate the association between transformational leadership behaviors and practice beliefs regarding health promotion. There is a positive association between transformational leadership behaviors and health professionals practice beliefs regarding health promotion activities for persons with disabilities. A quantitative cross-sectional web-based survey design was used to determine the association between leadership behaviors and practices beliefs regarding health promotion for people with disabilities. The Multifactor Leadership Questionnaire and an adapted version of the Role of Health Promotion in Physical Therapy Survey were used to measure leadership and practice beliefs, respectively. Multiple regression analysis was applied to determine the association of leadership behaviors with health promotion practice beliefs variables. Transformational leadership behaviors of the AUCD network professionals were positively associated with health promotion practice beliefs about cardiovascular fitness for people with disabilities. Years post licensure and discipline did not moderate the association between transformational leadership and practice beliefs regarding health promotion. Transformational leadership may facilitate health professionals' health promotion practices for people with disabilities. Further research and training in leadership is needed.

    To describe whether nurses fully implement their scope of practice; nurses' perceptions of future practice implementation; and the association between scope of practice implementation with professional autonomy and self-efficacy. A descriptive correlational study was conducted using a convenience sample of 145 registered nurses with post-basic certification from two Israeli university hospitals, from May 2012 to September 2013. Five questionnaires were distributed: (a) Demographic and Work Characteristics, (b) Implementation of Scope of Practice, (c) Attitudes Towards Future Practice, (d) Practice Behavior Scale, and (e) Practice Self-Efficacy. Descriptive statistics for all demographic and questionnaire data were analyzed. Two regression models were developed, where current and future implementations were the criterion variables and demographic and work characteristics, professional autonomy, and self-efficacy were the predictors. High levels of professional autonomy, self-efficacy, and attitudes towards future practice were found in contrast to low or moderate levels of current implementation of the full extent of scope of practice. Primary reasons associated with low implementation were lack of relevance to practice and permission to perform the practice. Significant associations were found between professional autonomy, self-efficacy, and attitudes towards future practice, but not with current implementation. Nurses wanted to practice to the full extent of their scope of practice and felt able to do so but were hindered by administrative and not personal barriers. Even though staff nurses with post-basic certification had high levels of professional autonomy and self-efficacy, many were not implementing the full extent of their scope of practice. Similar to findings from around the world, external factors, such as administrative and policy barriers, were found to thwart the full implementation of nurses' full scope of practice. Therefore, practicing nurses

    In 2015 the meningococcal ACWY (MenACWY) vaccination was introduced amongst adolescents in England following increased incidence and mortality associated with meningococcal group W. MenACWY vaccination uptake data for 17-18 years old and students delivered in primary care were obtained for 20 National Health Service clinical commissioning groups (CCGs) via the ImmForm vaccination system. Data on general practice characteristics, encompassing demographics and patient satisfaction variables, were extracted from the National General Practice Profiles resource. Univariable analysis of the associations between practice characteristics and vaccination was performed, followed by multivariable negative binomial regression. Data were utilized from 587 general practices, accounting for ~8% of all general practices in England. MenACWY vaccination uptake varied from 20.8% to 46.8% across the CCGs evaluated. Upon multivariable regression, vaccination uptake increased with increasing percentage of patients from ethnic minorities, increasing percentage of patients aged 15-24 years, increasing percentage of patients that would recommend their practice and total Quality and Outcomes Framework achievement for the practice. Conversely, vaccination uptake decreased with increasing deprivation. This study has identified several factors independently associated with MenACWY vaccination in primary care. These findings will enable a targeted approach to improve general practice-level vaccination uptake. © The Author(s) 2018. Published by Oxford University Press on behalf of Faculty of Public Health.

    This study describes the transformational leadership (TL) practices of nurse leaders in professional nursing associations (PNAs). Professional nursing associations are vehicles to provide educational opportunities for nurses as well as leadership opportunities for members. Little has been published about the leadership practices of PNA members. E-mail surveys of 448 nurse leaders in PNAs were conducted in 2013 using the Leadership Practices Inventory (LPI). The top 2 TL practices of these nurse leaders were enabling others to act and encouraging the heart. Respondents with more leadership training reported higher TL practices. This is the 1st study to describe TL practices of nurse leaders in PNAs. Results of this study show that nurse leaders of PNAs emulate practices of TL. Transformational leaders can mobilize and direct association members in reaching shared values, objectives, and outcomes. Understanding TL practices of nurse leaders in PNAs are important to the future of nursing in order to enable nurses to lead change and advance health through these organizations.

    Dietary sodium is thought to play a major role in the pathogenesis of hypertension, hypervolemia and mortality in hemodialysis patients. Thus, restriction is almost universally recommended. However, the evidence on which these assumptions are based is limited. We undertook a post-hoc analysis of the Hemodialysis Study with available dietary, clinical and laboratory information. Linear regression models were fit to estimate associations of dietary sodium with ultrafiltration requirement, blood pressure and nutritional indices. Cox regression models were fit to estimate the association of dietary sodium intake, sodium:calorie intake, sodium:potassium intake and prescribed sodium restriction with all-cause mortality. Complete data were available in 1770 subjects, of whom 44% were male, 63% were black and 44% were diabetic. Mean age was 58 (±14) years; median dietary sodium intake was 2080 (IQR: 1490-2850) mg/day. After case-mix adjustment, higher reported dietary sodium was associated with greater ultrafiltration requirement, caloric and protein intake; sodium:calorie intake ratio associated with greater UF requirement; sodium:potassium ratio associated with higher serum sodium. None were associated with pre-dialysis systolic blood pressure. Higher baseline reported dietary sodium, sodium:calorie ratio and sodium:potassium ratio were independently associated with greater all-cause mortality. No associations between prescribed dietary sodium restriction and mortality were observed. Higher reported dietary sodium intake is independently associated with greater mortality among prevalent hemodialysis subjects. Randomized trials are warranted to determine whether dietary sodium restriction improves survival. PMID:22418981

    Purpose Increased follicle-stimulating hormone (FSH) has been associated with lower bone mineral density (BMD) in animal models and longitudinal studies of women, but a direct effect has not been demonstrated. Methods We tested associations between FSH, non-bone body composition measures and BMD in 94 younger (aged 50 to 64 years) postmenopausal women without current use of hormone therapy, adjusting for sex hormone concentrations and clinical risk factors for osteoporosis. Lean mass, fat mass and areal BMD (aBMD) at the spine, femoral neck and total hip were measured using dual energy X-ray absorptiometry (DXA). Volumetric BMD (vBMD) was measured at the distal radius using peripheral quantitative computed tomography (pQCT). Results: FSH was inversely correlated with lean and fat mass, bioavailable estradiol, spine and hip aBMD, and vBMD at the ultradistal radius. In the multivariable analysis, FSH was independently associated with lean mass (β= −0.099, p=0.005) after adjustment for age, race, years since menopause, bioavailable estradiol, bioavailable testosterone, LH, PTH, SHBG and urine N-telopeptide. FSH showed no statistically significant association with aBMD at any site or pQCT measures at the distal radius in adjusted models. Race was independently associated with aBMD, and race and urine N-telopeptide were independently associated with bone area and vBMD. Conclusions After adjustment for hormonal measures and osteoporosis risk factors, higher concentrations of FSH were independently associated with lower lean mass, but not with BMD. Previously reported correlations between FSH and BMD might have been due to indirect associations via lean mass or weight. PMID:22086136

    Few nurses have the experience of developing an independent practice. This ethnographic study explores the process and challenges of becoming an entrepreneur as described by nurses developing independent practices in community care gerontologic nursing. The process included developing a legal contract, marketing strategies, and reimbursement amounts and strategies. Major barriers to implementing this role identified by the nurses included ignorance and confusion by others about their role, financial issues related to an uncertain income, time management, and legal concerns especially around delegation. These were experienced and dedicated nurses who were also risk-takers and enjoyed the independence of practicing nursing because they believed it was meant to be practiced. Suggestions for research, education, and practice are included.

    Cerebral amyloid angiopathy (CAA) is a major cause of lobar intracerebral hemorrhage and cognitive impairment and is associated with white matter hyperintensities and cerebral microbleeds. MRI diffusion tensor imaging detects microstructural tissue damage in advanced CAA even in areas that appear normal on conventional MRI. We hypothesized that higher global mean apparent diffusion coefficient (mean ADC), reflecting a higher amount of chronic tissue disruption caused by CAA, would be independently associated with CAA-related cognitive impairment. Preintracerebral hemorrhage cognitive impairment was systematically assessed using a standardized questionnaire (IQCODE) in 49 patients. Volume of white matter hyperintensities, number of microbleeds, and mean ADC were determined from MRIs obtained within 14.0+/-22.5 days of intracerebral hemorrhage cognitive impairment. White matter hyperintensities and mean ADC were measured in the hemisphere uninvolved by intracerebral hemorrhage to avoid confounding. Preintracerebral hemorrhage cognitive impairment was identified in 10 of 49 subjects. Mean ADC was the only variable associated with preintracerebral hemorrhage cognitive impairment and was elevated in those with preintracerebral hemorrhage cognitive impairment compared with those without (12.4x10(-4) versus 11.7x10(-4) mm(2)/s; P=0.03). Mean ADC positively correlated with age but not white matter hyperintensities or number of microbleeds. In logistic regression controlling for age and visible cerebral atrophy, mean ADC was independently associated with preintracerebral hemorrhage cognitive impairment (OR per 1x10(-4) mm(2)/s increase=2.45, 95% CI 1.11 to 5.40, P=0.04). Mean ADC is independently associated with preintracerebral hemorrhage cognitive impairment in CAA. The lack of correlation with other MRI markers of CAA suggests that mean ADC may be sensitive to distinct aspects of CAA pathology and its tissue consequences. These results suggest that global MRI diffusion

    It is recognized that total testosterone (TT) does not sufficiently describe androgen status when sex hormone-binding globulin (SHBG) is altered. However, in humans, evidence supporting the existence of a hypogonadism due to low T bioactivity is scanty. The aim of the study was to assess whether changes in SHBG levels, independently of TT, are associated with subjective and objective androgen-dependent parameters. Cross-sectional observation. Two thousand six hundred and twenty-two men (aged 51.1 ± 13.5 years) attending a Sexual Medicine and Andrology Outpatient Clinic for sexual dysfunctions. All patients underwent a standardized diagnostic protocol before starting any treatment. Clinical and biochemical parameters have been collected. Higher ANDROTEST score has been used as a comprehensive marker of more severe hypogonadal symptoms. Prostate-specific antigen (PSA) and haematocrit have been used as objective surrogate markers of T bioactivity. After adjusting for TT and lifestyle, SHBG showed a significant positive association with ANDROTEST score (B = 0.79 [0.61; 0.96], P < .0001). Conversely, higher SHBG, independently of TT, was negatively related to PSA (B = -0.86 [-0.83; -0.89]; P < .0001) and haematocrit (B = -0.64 [-0.88; -0.40]; P < .0001), after adjustment for the aforementioned confounders along with age and body mass index. Furthermore, a relationship between SHBG and lipids or blood pressure was found, with lower SHBG levels associated with a worse metabolic profile, independently of TT. Higher SHBG, independently of TT, is associated with either subjective or objective androgen deficiency features. This indicates that besides a hypogonadism due to an impaired T production, a hypogonadism due to a lower biological activity of T does exist. © 2017 John Wiley & Sons Ltd.

  16. Risky sexual practice and associated factors among HIV positive adults attending anti-retroviral treatment clinic at Gondar University Referral Hospital, Northwest Ethiopia

    2017-01-01

    Introduction Risky sexual practice among people living with HIV/AIDS is a public health concern because of the risk of transmission of the virus to sero-discordant partner/s. There is also the risk of re-infection with new, drug resistant viral strains between sero-concordant partners. However, there is lack of information on risky sexual practices among HIV positive adults. Therefore, this study aimed to assess risky sexual practice and associated factors among adult HIV positive clients at Gondar University Referral Hospital, Northwest Ethiopia, 2015. Methods An institution based cross sectional study was conducted at Gondar University Referral Hospital from May to June 2015. A pretested structured questionnaire was used to collect the data. Using systematic random sampling technique, a total of 513 respondents were participated in this study. The data were entered into EPI info version 3.5.3 and transferred to SPSS version 20 for analysis. Descriptive, bivariate and multivariate analyses were done. A P-value <0.05 was considered to determine the statistical significance of the association between factors (independent variables) and risky sexual practice. The Odds ratio was also used to determine the presence and the degree of association between the dependent and independent variables. Results A total of 513 respondents were participated in this study. The prevalence of risky sexual practices in the past three months was 38% (95% CI: 33.3%, 42.3%). Being in the age range of 18–29 years (AOR = 2.63, 95% CI: 1.55, 4.47) and 30–39 years (AOR = 2.29, 95% CI: 1.48, 3.53), being single (AOR = 6.32, 95%CI: 2.43, 16.44),being married (AOR = 6.06, 95% CI: 2.81, 13.07), having no child (AOR = 2.58, 95% CI: 1.17, 5.72), and a CD4 count of greater than 500/mm3 were factors significantly associated with risky sexual practices. Conclusions A considerable number of HIV positive clients had risky sexual practices. It is strongly recommended that the Regional Health Bureau

    The concept of independence is common in occupational therapy theory and practice but has rarely been clearly defined or conceptualized within in occupational therapy literature and there seems to be no standard definition. This can result in ambiguity, which potentially jeopardizes client-centred practice. This paper proposes an occupational therapy independence framework (OTIF) that synthesizes the range of characterizations of independence in a practically useful and occupation-centred manner. A review of literature, clinical experience, doctoral research and conversations with occupational therapists and disabled people, in particular those involved in a disability activism group and people with physical disabilities, has led to the development of the OTIF. Independence and interdependence, as characterized in the OTIF, occur when an individual exerts choice over occupational performance and can engage in occupations in a manner acceptable to the individual. Interdependence results when occupations are performed with another person whereas independence involves solitary occupational performance. Dependence typically results from inability to choose occupations or a mismatch between performance capacity and environmental factors. The OTIF has the potential to clarify the conceptualization of independence within occupational therapy theory and practice. This initial proposal is presented to stimulate debate and discussion.

    Information about the costs and experiences of collecting and reporting quality measure data are vital for practices deciding whether to adopt new quality improvement initiatives or monitor existing initiatives. Six primary care practices from Colorado's Improving Performance in Practice program participated. We conducted structured key informant interviews with Improving Performance in Practice coaches and practice managers, clinicians, and staff and directly observed practices. Practices had 3 to 7 clinicians and 75 to 300 patients with diabetes, half had electronic health records, and half were members of an independent practice association. The estimated per-practice cost of implementation for the data collection and reporting for the diabetes quality improvement program was approximately $15,552 per practice (about $6.23 per diabetic patient per month). The first-year maintenance cost for this effort was approximately $9,553 per practice ($3.83 per diabetic patient per month). The cost of implementing and maintaining a diabetes quality improvement effort that incorporates formal data collection, data management, and reporting is significant and quantifiable. Policymakers must become aware of the financial and cultural impact on primary care practices when considering value-based purchasing initiatives.

    Uncertainty still exists whether physical activity (PA) and cardiovascular fitness (CF) contribute separately to cardiovascular disease (CVD) risk. This study examined the associations of PA and CF on individual as well as clustered CVD risk factors. Cross-sectional. Seven hundred and eighty-one men and 890 women, aged 20-65 years, from two random population-based samples of Swedish women and men were included. PA was assessed by questionnaire and CF was predicted by a submaximal cycle ergometry test. Waist circumference, blood pressure, and fasting levels of blood lipids were assessed and dichotomized by conventional cut-off points. Participants reporting high PA level benefited from lower triglycerides and atherogenic cholesterol levels, regardless of CF. Higher CF level was, regardless of PA, associated with lower risk for all risk factors. With regard to clustering of risk factors, each higher CF level was associated with a gradually reduced risk by half or more, independent of PA. Furthermore, being unfit but reporting high PA was associated with a 50% lower risk compared with being unfit and inactive. Furthermore, high reported PA was associated with an additional reduced risk among fit participants. In addition, an excess risk of interaction was found for waist circumference, triglycerides, and the clustered CVD risk between neither being sufficiently active nor being fit. This study suggests that both PA and CF are independently associated with lower cardiovascular risk, and that both variables should be taken into account when CVD risk is estimated.

    Background/Aims Esophageal motor disorder (EMD) has been shown to be associated with gastroesophageal reflux disease (GERD). However, the association of EMD with a Barrett’s esophagus (BE) is controversial. Our objective was to evaluate whether the presence of EMD was an independent factor associated with BE. Methods A retrospective case-control study was conducted in GERD patients who all had oeso-gastroduodenal endoscopy and high-resolution esophageal manometry. The clinical data collected was known or potential risk factors for BE: male gender, smoking and alcohol consumption, age, body mass index, presence of hiatal hernia, frequency, and age of GERD. EMD were classified according to the Chicago classification into: ineffective motor syndrome, fragmented peristalsis and absence of peristalsis, lower esophageal sphincter hypotonia. Results Two hundred and one patients (101 in the GERD + BE group and 100 in the GERD without BE) were included. In univariate analysis, male gender, alcohol consumption, presence of hiatal hernia, and EMD appeared to be associated with the presence of BE. In a multivariate analysis, 3 independent factors were identified: the presence of EMD (odds ratio [OR], 3.99; 95% confidence interval [CI], 1.71–9.28; P = 0.001), the presence of hiatal hernia (OR, 5.60; 95% CI, 2.45–12.76; P < 0.001), Helicobacter pylori infection (OR, 0.08; 95% CI, 0.01–0.84; P = 0.035). Conclusions The presence of EMD (particularly ineffective motor syndrome and lower esophageal sphincter hypotonia) is a strong independent associated factor of BE. Searching systematically for an EMD in patients suffering from GERD could be a new strategy to organize the endoscopic follow-up. PMID:29605977

    Due to shortage of general practitioners, it may be necessary to improve productivity. We assess the association between productivity, list size and patient- and practice characteristics. A regression approach is used to perform productivity analysis based on national register data and survey data for 1,758 practices. Practices are divided into four groups according to list size and productivity. Statistical tests are used to assess differences in patient- and practice characteristics. There is a significant, positive correlation between list size and productivity (p < 0.01). Nevertheless, 19% of the practices have a list size below and a productivity above mean sample values. These practices have relatively demanding patients (older, low socioeconomic status, high use of pharmaceuticals) and they are frequently located in areas with limited access to specialized care and have a low use of assisting personnel. 13% of the practices have a list size above and a productivity below mean sample values. These practices have relatively less demanding patients, are located in areas with good access to specialized care, and have a high use of assisting personnel. Lists and practice characteristics have substantial influence on both productivity and list size. Adjusting list size to external factors seems to be an effective tool to increase productivity in general practice.

    Recent studies suggest that variation in complex disorders (e.g., schizophrenia) is explained by a large number of genetic variants with small effect size (Odds Ratio∼1.05–1.1). The statistical power to detect these genetic variants in Genome Wide Association (GWA) studies with large numbers of cases and controls (∼15,000) is still low. As it will be difficult to further increase sample size, we decided to explore an alternative method for analyzing GWA data in a study of schizophrenia, dramatically reducing the number of statistical tests. The underlying hypothesis was that at least some of the genetic variants related to a common outcome are collocated in segments of chromosomes at a wider scale than single genes. Our approach was therefore to study the association between relatively large segments of DNA and disease status. An association test was performed for each SNP and the number of nominally significant tests in a segment was counted. We then performed a permutation-based binomial test to determine whether this region contained significantly more nominally significant SNPs than expected under the null hypothesis of no association, taking linkage into account. Genome Wide Association data of three independent schizophrenia case/control cohorts with European ancestry (Dutch, German, and US) using segments of DNA with variable length (2 to 32 Mbp) was analyzed. Using this approach we identified a region at chromosome 5q23.3-q31.3 (128–160 Mbp) that was significantly enriched with nominally associated SNPs in three independent case-control samples. We conclude that considering relatively wide segments of chromosomes may reveal reliable relationships between the genome and schizophrenia, suggesting novel methodological possibilities as well as raising theoretical questions.

    Background Rheumatoid arthritis (RA) is a chronic inflammatory disease associated with premature atherosclerosis, vascular stiffening, and heart failure. Whether RA is associated with underlying structural and functional abnormalities of the left ventricle (LV) is poorly understood. Methods and Results 89 patients with RA without clinical cardiovascular disease and 89 healthy matched controls underwent echocardiography, carotid ultrasonography, and radial tonometry to measure arterial stiffness. RA patients and controls were similar in body size, hypertension and diabetes status, and cholesterol. LV diastolic diameter (4.92 vs. 4.64 cm, p <0.001), mass (136.9 vs. 121.7 g, p = 0.001 or 36.5 vs. 32.9 g/m 2.7, p = 0.01), ejection fraction (EF) (71% vs. 67%, p <0.001), and prevalence of LV hypertrophy (LVH) (18% vs. 6.7%, p = 0.023) were all higher among RA patients. In multivariate analysis, presence of RA (p = 0.004) was an independent correlate of LV mass. Furthermore, RA was independently associated with the presence of LVH (OR 4.14, [95% CI 1.24-13.80; p=0.021]). Among RA patients, age at diagnosis and disease duration were independently related to LV mass. RA patients with LVH were older and had higher systolic pressure, damage index score, C-reactive protein, homocysteine and arterial stiffness index compared to those without LVH. Conclusion RA is associated with increased LV mass. Disease duration is independently related to increased LV mass, suggesting a pathophysiological link between chronic inflammation and LVH. In contrast, LV systolic function is preserved in RA patients indicating that systolic dysfunction is not an intrinsic feature of RA. PMID:19116901

    The independent cue technique has been developed to test traditional interference theories against inhibition theories of forgetting. In the present study, the authors tested the critical criterion for the independence of independent cues: Studied cues not presented during test (and unrelated to test cues) should not contribute to the retrieval process. Participants first studied a subset of cues (e.g., rope) that were subsequently studied together with a target in a 2nd study phase (e.g., rope-sailing, sunflower-yellow). In the test phase, an extralist category cue (e.g., sports, color) was presented, and participants were instructed to recall an item from the study list that was a member of the category (e.g., sailing, yellow). The experiments showed that previous study of the paired-associate word (e.g., rope) enhanced category cued recall even though this word was not presented at test. This experimental demonstration of covert cuing has important implications for the effectiveness of the independent cue technique.

    Background The impact of high physician workload and job stress on quality and outcomes of healthcare delivery is not clear. Our study explored whether high workload and job stress were associated with lower performance in general practices in the Netherlands. Methods Secondary analysis of data from 239 general practices, collected in practice visits between 2003 to 2006 in the Netherlands using a comprehensive set of measures of practice management. Data were collected by a practice visitor, a trained non-physician observer using patients questionnaires, doctors and staff. For this study we selected five measures of practice performance as outcomes and six measures of GP workload and job stress as predictors. A total of 79 indicators were used out of the 303 available indicators. Random coefficient regression models were applied to examine associations. Results and discussion Workload and job stress are associated with practice performance. Workload: Working more hours as a GP was associated with more positive patient experiences of accessibility and availability (b = 0.16). After list size adjustment, practices with more GP-time per patient scored higher on GP care (b = 0.45). When GPs provided more than 20 hours per week per 1000 patients, patients scored over 80% on the Europep questionnaire for quality of GP care. Job stress: High GP job stress was associated with lower accessibility and availability (b = 0.21) and insufficient practice management (b = 0.25). Higher GP commitment and more satisfaction with the job was associated with more prevention and disease management (b = 0.35). Conclusion Providing more time in the practice, and more time per patient and experiencing less job stress are all associated with perceptions by patients of better care and better practice performance. Workload and job stress should be assessed by using list size adjusted data in order to realise better quality of care. Organisational development using this kind of data feedback

    Parental feeding practices are associated with children's body mass index (BMI). It has been generally assumed that parental feeding determines children's eating behaviors and weight gain, but feeding practices could equally be a parent's response to child weight. In longitudinal analyses, we assessed the directionality in the relation between selected controlling feeding practices and BMI in early childhood. Participants were 4166 children from the population-based Generation R Study. BMI was measured at ages 2 and 6 y. With the use of the Child Feeding Questionnaire, parents reported on restriction, monitoring, and pressure to eat (child age: 4 y). BMI and feeding-behavior scales were transformed to SD scores. With the use of linear regression analyses, there was an indication that a higher BMI at age 2 y predicted higher levels of parental restriction (adjusted β = 0.07; 95% CI: 0.04, 0.10) and lower levels of pressure to eat (adjusted β = -0.20; 95% CI: -0.23, -0.17) 2 y later. Restriction at age 4 y positively predicted child BMI at 6 y of age, although this association attenuated to statistical nonsignificance after accounting for BMI at age 4 y (β = 0.01; 95% CI: -0.01, 0.03). Pressure to eat predicted lower BMI independently of BMI at age 4 y (β = -0.02; 95% CI: -0.04, -0.01). For both restriction and pressure to eat, the relation from BMI to parenting was stronger than the reverse (Wald's test for comparison: P = 0.03 and < 0.001, respectively). Monitoring predicted a lower child BMI, but this relation was explained by confounding factors. Although the feeding-BMI relation is bidirectional, the main direction of observed effects suggests that parents tend to adapt their controlling feeding practices in response to their child's BMI rather than the reverse. Therefore, some components of current programs aimed at preventing or treating unhealthy child weight may need to be carefully scrutinized, especially those targeting parental food

    Background and Purpose Cerebral amyloid angiopathy (CAA) is a major cause of lobar intracerebral hemorrhage and cognitive impairment and is associated with white matter hyperintensities and cerebral microbleeds. MRI diffusion tensor imaging detects microstructural tissue damage in advanced CAA even in areas that appear normal on conventional MRI. We hypothesized that higher global mean apparent diffusion coefficient (mean ADC), reflecting a higher amount of chronic tissue disruption caused by CAA, would be independently associated with CAA-related cognitive impairment. Methods Preintracerebral hemorrhage cognitive impairment was systematically assessed using a standardized questionnaire (IQCODE) in 49 patients. Volume of white matter hyperintensities, number of microbleeds, and mean ADC were determined from MRIs obtained within 14.0±22.5 days of intracerebral hemorrhage cognitive impairment. White matter hyperintensities and mean ADC were measured in the hemisphere uninvolved by intracerebral hemorrhage to avoid confounding. Results Preintracerebral hemorrhage cognitive impairment was identified in 10 of 49 subjects. Mean ADC was the only variable associated with preintracerebral hemorrhage cognitive impairment and was elevated in those with preintracerebral hemorrhage cognitive impairment compared with those without (12.4×10-4 versus 11.7×10-4 mm2/s; P=0.03). Mean ADC positively correlated with age but not white matter hyperintensities or number of microbleeds. In logistic regression controlling for age and visible cerebral atrophy, mean ADC was independently associated with preintracerebral hemorrhage cognitive impairment (OR per 1×10-4 mm2/s increase=2.45, 95% CI 1.11 to 5.40, P=0.04). Conclusions Mean ADC is independently associated with preintracerebral hemorrhage cognitive impairment in CAA. The lack of correlation with other MRI markers of CAA suggests that mean ADC may be sensitive to distinct aspects of CAA pathology and its tissue consequences. These

    Objective To identify individual and social factors associated with pharmacy students' level of reflection in an advanced pharmacy practice experience (APPE). Methods A postal questionnaire, including a reflective assignment, was sent to all pharmacy interns (n=262) at Uppsala University, Sweden, for 4 semesters in 2005-2007. Results In a univariate analysis, 7 factors were found to be associated with students' level of reflection. After controlling for covariates, 3 social factors were found to be independently associated with reflection: having a formal preceptor (OR=5.3), being at a small pharmacy (OR=19.8), and students' perception of the importance of discussing critical thinking with the preceptor (OR=1.2). No correlation could be observed between level of reflection and critical thinking, nor learning style. Conclusion Social components seem to be of higher importance than individual components in students' reflective levels after pharmacy internship experience. Trained preceptors are important to foster reflection skills. PMID:19885076

    The Independent-Trajectory Thermodynamic Integration (IT-TI) approach for free energy calculation with distributed computing is described. IT-TI utilizes diverse conformational sampling obtained from multiple, independent simulations to obtain more reliable free energy estimates compared to single TI predictions. The latter may significantly under- or over-estimate the binding free energy due to finite sampling. We exemplify the advantages of the IT-TI approach using two distinct cases of protein-ligand binding. In both cases, IT-TI yields distributions of absolute binding free energy estimates that are remarkably centered on the target experimental values. Alternative protocols for the practical and general application of IT-TI calculations are investigated. We highlight a protocol that maximizes predictive power and computational efficiency.

    The relative contribution of interictal epileptiform discharges (IEDs) to cognitive dysfunction in comparison with the underlying brain pathology is not yet understood in children with lesional focal epilepsy. The current study investigated the association of IEDs with intellectual functioning in 103 children with medication-resistant focal epilepsy. Hierarchical multiple regression analyses were used to determine the independent contribution of IED features on intellectual functioning, after controlling for effects of lesional pathology, epilepsy duration, and medication. Exploratory analyses were conducted for language and memory scores as well as academic skills available in a subset of participants. The results reveal that IEDs have a negative association with IQ with independent, additive effects documented for frequent and bilaterally distributed IEDs as well as discharge enhancement in sleep. Left-lateralized IEDs had a prominent effect on verbal intelligence, in excess of the influence of left-sided brain pathology. These effects extended to other cognitive functions, most prominently for sleep-enhanced IEDs to be associated with deficits in expressive and receptive language, reading, spelling and numerical skills. Overall, IED effects on cognition were of a magnitude similar to lesional influences or drug effects (topiramate use). This study demonstrates an association between IEDs and cognitive dysfunction, independent of the underlying focal brain pathology.

    The P wave parameters measured by 12-lead electrocardiogram (ECG) are commonly used as noninvasive tools to assess for left atrial enlargement. There are limited studies to evaluate whether P wave parameters are independently associated with decline in renal function. Accordingly, the aim of this study is to assess whether P wave parameters are independently associated with progression to renal end point of ≥25% decline in estimated glomerular filtration rate (eGFR). This longitudinal study included 166 patients. The renal end point was defined as ≥25% decline in eGFR. We measured two ECG P wave parameters corrected by heart rate, i.e. corrected P wave dispersion (PWdisperC) and corrected P wave maximum duration (PWdurMaxC). Heart function and structure were measured from echocardiography. Clinical data, P wave parameters, and echocardiographic measurements were compared and analyzed. Forty-three patients (25.9%) reached renal end point. Kaplan-Meier curves for renal end point-free survival showed PWdisperC > median (63.0 ms) (log-rank P = 0.004) and PWdurMaxC > median (117.9 ms) (log-rank P<0.001) were associated with progression to renal end point. Multivariate forward Cox-regression analysis identified increased PWdisperC (hazard ratio [HR], 1.024; P = 0.001) and PWdurMaxC (HR, 1.029; P = 0.001) were independently associated with progression to renal end point. Our results demonstrate that increased PWdisperC and PWdurMaxC were independently associated with progression to renal end point. Screening patients by means of PWdisperC and PWdurMaxC on 12 lead ECG may help identify a high risk group of rapid renal function decline.

    Blood donation has remained a challenge in developing countries, like Ethiopia. In Ethiopia there is a high reliance on family surrogate and waged blood donors which carries an attendant increased risk of transfusion transmissible infection. Health workers are expected to practice blood donation so as to create a good image to the public. A study on blood donation behavior may improve successful implementation of the blood donation programs. An institution based cross-sectional study was deployed from January to June 2015. An aggregate of 427 health workers were included in the study by using simple random sampling technique. Data were collected by using pre tested and structured questionnaire via self-administrated method. Descriptive and summary statistics were employed. Bivariate and multiple logistic regressions were computed. Odds ratios and their 95% confidence intervals were calculated to determine the level of significance. A total of 427 participants were included in the final analysis (response rate = 100%). Among these participants, 33.2% of them practice blood donation. Age above 25 years [AOR = 1.8 (95% CI 1.1, 3.0)], health professionals' knowledge of blood donation [AOR = 1.9 (95% CI 1.1, 3.1)], health professionals' attitude towards blood donation [AOR = 3.0, 95% CI 1. 8, 4.9)], and the presence of family members or relatives who received blood [AOR = 5.4, 95% CI 3.7, 8.7)] were significantly and independently associated with blood donation behavior of health professionals. Blood donation practice of health professionals in this study was found to be low as compared to other studies conducted in developing countries. Health professionals' knowledge, attitude, age and the presence of family members or relatives who received blood before were independently associated with blood donation practice. Thus, awareness has to be created for health professionals to improve blood donation practices.

    Objectives To validate the performance of a set of risk prediction algorithms developed using the QResearch database, in an independent sample from general practices contributing to the Clinical Research Data Link (CPRD). Setting Prospective open cohort study using practices contributing to the CPRD database and practices contributing to the QResearch database. Participants The CPRD validation cohort consisted of 3.3 million patients, aged 25–99 years registered at 357 general practices between 1 Jan 1998 and 31 July 2012. The validation statistics for QResearch were obtained from the original published papers which used a one-third sample of practices separate to those used to derive the score. A cohort from QResearch was used to compare incidence rates and baseline characteristics and consisted of 6.8 million patients from 753 practices registered between 1 Jan 1998 and until 31 July 2013. Outcome measures Incident events relating to seven different risk prediction scores: QRISK2 (cardiovascular disease); QStroke (ischaemic stroke); QDiabetes (type 2 diabetes); QFracture (osteoporotic fracture and hip fracture); QKidney (moderate and severe kidney failure); QThrombosis (venous thromboembolism); QBleed (intracranial bleed and upper gastrointestinal haemorrhage). Measures of discrimination and calibration were calculated. Results Overall, the baseline characteristics of the CPRD and QResearch cohorts were similar though QResearch had higher recording levels for ethnicity and family history. The validation statistics for each of the risk prediction scores were very similar in the CPRD cohort compared with the published results from QResearch validation cohorts. For example, in women, the QDiabetes algorithm explained 50% of the variation within CPRD compared with 51% on QResearch and the receiver operator curve value was 0.85 on both databases. The scores were well calibrated in CPRD. Conclusions Each of the algorithms performed practically as well in the

    Subarachnoid haemorrhage (SAH) may present with coma and this is known to be associated with aneurysmal origin and blood load. Aneurysmal origin is associated with increased blood load and existing data do not allow us to determine if the association between coma and aneurysmal SAH is wholly due to blood load or if aneurysmal origin has an additional independent effect. The objective of our study is to find if an aneurysmal origin is a predictor of acute onset of coma independent of blood load. A series of consecutive patients with spontaneous SAH were divided into two groups: aneurysmal (aSAH) and non-aneurysmal--angiographically negative SAH (naSAH). Blood load was quantified so that the effect of aneurysmal origin could be resolved from the effect of the amount of blood spilled. Non-parametric regression was used to relate blood load to coma and poor outcome rates for aneurysmal bleeds. We analysed a total of 421 patients presenting during the period 2009-2011. Ninety aneurysmal cases presented with coma, seventy immediately in the early phase and seven shortly after rebleeding. None of the naSAH cases presented with immediate coma and 1 developed delayed coma. Delayed coma was associated with acute hydrocephalus in both groups. Aneurysmal origin was found to be an independent determinant of immediate coma (p=0.02) and poor outcome (p<0.001). Immediate coma and poor outcome in SAH are associated with an aneurysmal origin and do not characterize naSAH. Copyright © 2013 Elsevier B.V. All rights reserved.

    A recent association study identified a common variant (rs9790517) at 4q24 to be associated with breast cancer risk. Independent association signals and potential functional variants in this locus have not been explored. We conducted a fine-mapping analysis in 55,540 breast cancer cases and 51,168 controls from the Breast Cancer Association Consortium. Conditional analyses identified two independent association signals among women of European ancestry, represented by rs9790517 [conditional P = 2.51 × 10(-4); OR, 1.04; 95% confidence interval (CI), 1.02-1.07] and rs77928427 (P = 1.86 × 10(-4); OR, 1.04; 95% CI, 1.02-1.07). Functional annotation using data from the Encyclopedia of DNA Elements (ENCODE) project revealed two putative functional variants, rs62331150 and rs73838678 in linkage disequilibrium (LD) with rs9790517 (r(2) ≥ 0.90) residing in the active promoter or enhancer, respectively, of the nearest gene, TET2. Both variants are located in DNase I hypersensitivity and transcription factor-binding sites. Using data from both The Cancer Genome Atlas (TCGA) and Molecular Taxonomy of Breast Cancer International Consortium (METABRIC), we showed that rs62331150 was associated with level of expression of TET2 in breast normal and tumor tissue. Our study identified two independent association signals at 4q24 in relation to breast cancer risk and suggested that observed association in this locus may be mediated through the regulation of TET2. Fine-mapping study with large sample size warranted for identification of independent loci for breast cancer risk. ©2015 American Association for Cancer Research.

    The concept of community access is a multidimensional term, which may involve issues related to physical access, knowledge and information, power and control, relationships and communications, advocacy, participation and quality of life [21]. This paper discusses historical and emerging practices and interventions related to physical access to community and community based information for individuals with cognitive disabilities such as intellectual disability, autism or traumatic brain injury. While much societal attention has been paid to features of independent community access for populations such as individuals with hearing, vision or physical disabilities, less attention has focused on independent community access for people with intellectual and other significant cognitive disabilities. Attitudes and actions by families and professional service communities are often mixed for some individuals in this population. The somewhat limited research base in these areas is explored, including a case study review and results from several promising feasibility studies. The paper concludes with comments concerning future prospects and recommendations for improving independent community access for persons with significant cognitive disabilities.

  18. Independent contractors versus employees: the costs and benefits for your practice.

    Every business is interested in reducing costs. Payroll and employee benefit costs can be reduced through the use of independent contractors, because they are not employees to whom training, overtime wages, and benefits must be provided. Using the services of an independent contractor presents some disadvantages, however, as an independent contractor cannot be controlled and disciplined in the same fashion as an employee. There are a variety of tests applied under various statutes to determine whether an individual is an employee or an independent contractor, and it is important to carefully analyze all of the facts of a given situation in light of these tests before entering into an independent contractor relationship. If you engage an individual as an independent contractor, and that individual is found to actually be an employee, your business may be subject to significant financial penalties.

    Objective Leadership in organizations is important in shaping workers’ perceptions, responses to organizational change, and acceptance of innovations, such as evidence-based practices. Transformational leadership inspires and motivates followers, whereas transactional leadership is based more on reinforcement and exchanges. Studies have shown that in youth and family service organizations, mental health providers’ attitudes toward adopting an evidence-based practice are associated with organizational context and individual provider differences. The purpose of this study was to expand these findings by examining the association between leadership and mental health providers’ attitudes toward adopting evidence-based practice. Methods Participants were 303 public-sector mental health service clinicians and case managers from 49 programs who were providing mental health services to children, adolescents, and their families. Data were gathered on providers’ characteristics, attitudes toward evidence-based practices, and perceptions of their supervisors’ leadership behaviors. Zero-order correlations and multilevel regression analyses were conducted that controlled for effects of service providers’ characteristics. Results Both transformational and transactional leadership were positively associated with providers’ having more positive attitudes toward adoption of evidence-based practice, and transformational leadership was negatively associated with providers’ perception of difference between the providers’ current practice and evidence-based practice. Conclusions Mental health service organizations may benefit from improving transformational and transactional supervisory leadership skills in preparation for implementing evidence-based practices.

    Physicians have joined larger groups and hospital systems in the face of multiple environmental challenges. We examine whether there are differences across practice ownership in self-reported work environment, a practice culture of learning, psychological safety, and burnout. Using cross-sectional data from staff surveys of small and medium-size practices that participated in EvidenceNOW in Virginia, we tested for differences in work environment, culture of learning, psychological safety, and burnout by practice type. We conducted weighted multivariate linear regression of outcomes on ownership, controlling for practice size, specialty mix, payer mix, and whether the practice was located in a medically underserved area. We further analyzed clinician and staff responses separately. Participating were 104 hospital-owned and 61 independent practices and 24 federally qualified health centers (FQHCs). We analyzed 2,005 responses from practice clinicians and staff, a response rate of 49%. Working in a hospital-owned practice was associated with favorable ratings of work environment, psychological safety, and burnout compared with independent practices. When we examined separately the responses of clinicians vs staff, however, the association appears to be largely driven by staff. Hospital ownership was associated with positive perceptions of practice work environment and lower burnout for staff relative to independent ownership, whereas clinicians in FQHCs perceive a more negative, less joyful work environment and burnout. Our findings are suggestive that clinician and nonclinician staff perceive practice adaptive reserve differently, which may have implications for creating the energy for ongoing quality improvement work. © 2018 Annals of Family Medicine, Inc.

    Background Despite research linking family meals to healthier diets, some families are unable to have regular meals together. These families need guidance about other ways to promote healthy eating among adolescents. Objective To examine the association between various parenting practices and adolescent fruit and vegetable (FV) intake at different levels of family meal frequency. Design Cross-sectional, population-based survey of influences on adolescent weight-related behaviors: EAT 2010 (Eating and Activity in Teens). Participants/Setting 2,491 adolescents recruited from middle/high schools in Minneapolis/St-Paul Measures Adolescent FV intake was ascertained with a food frequency questionnaire. Survey items assessed frequency of family meals and FV parenting practices (availability, accessibility, parent modeling, parent encouragement, and family communication). Statistical Analyses Linear regression models were used to examine associations with and interactions among family meals and parenting practices. Models were adjusted for age, sex, socioeconomic status, race/ethnicity, and energy intake (kcal/day). Results Family meals, FV availability, FV accessibility, FV modeling, and encouragement to eat healthy foods were independently associated with higher FV intake. Of the 949 (34%) adolescents who reported infrequent family meals (≤2 days/week), mean FV intake was 3.6 servings/day for those with high home FV availability versus 3.0 servings/day for those with low home FV availability. Similar differences in mean FV intake (0-3-0.6 servings/day) were found for high versus low FV accessibility, parental modeling, and parent encouragement for healthy eating. Frequent family meals in addition to more favorable parenting practices were associated with the highest FV intakes. Conclusion Food parenting practices and family meals are associated with greater adolescent FV intake. Longitudinal and intervention studies are needed to determine which combination of

    Functional and genetic studies suggest that insulin-degrading enzyme (IDE) may be a strong functional and positional candidate. As there is a lack of consensus in regards to the level and location of IDE association signals we aimed to clarify these discrepancies through genotyping 28 SNPs in a large case-control collective together with quantitative measures of cognitive ability (MMSE). Four SNPs (rs11187007, rs2149632_ide12, rs11187033, rs11187040) were found to be associated with AD (nominal p<0.01). Tests with MMSE scores adjusted for disease duration identified associations, with the most significant result for rs1999763 (nominal p=0.008). Similarly, different reconstructed IDE haplotypes were associated with AD and higher MMSE scores. The association signals are only borderline significant after adjustment for multiple testing, but add further evidence to previous published results on the association between IDE and AD or MMSE. A subgroup analysis indicated more prominent associations with AD in younger, and with MMSE in older patients. There may be two independent effects mediated by IDE variants, risk for AD and modification of disease progression.

    The number of nurses able to independently prescribe medicines in England has risen steadily in recent years. To evaluate the adequacy of nurses' educational preparation for independent prescribing and to describe nurses' experiences of their continuing professional development as prescribers in practice. Postal questionnaire survey. Random sample of 246 nurses registered as nurse independent prescribers with the Nursing and Midwifery Council. The majority of nurses considered that the initial taught course element of their education programme met their needs, either to some extent (61% 151/246), or completely (22% 54/246). Most nurses (77% 190/246) received the specified 12 days support from their supervising medical practitioner and most were satisfied and positive about this experience. Nearly all of the nurses (>95%) reported that they were able to maintain a range of specified prescribing competencies in practice. Two thirds (62% 152/246) of the sample reported that they were receiving support/supervision for prescribing. Ninety five per cent (233/246) of the sample also reported that they engaged in self-directed informal continuing professional development, but only half of the sample had experience of formally provided professional development opportunities. Approximately half (52% 127/246) of the sample identified needs for continuing professional development. This first national survey of the education and professional development experiences of nurse independent prescribers in England provides evidence which highlights areas in which national policy is working well, and also points up issues which may need addressing as the roll out of nurse prescribing continues. The study also highlights characteristics and issues that health care policy makers and nurse educationalists internationally may wish to consider in developing and refining their own nurse prescriber education programmes.

    The purpose of this study was to test the association between self-control (SC) variables and (a) sport-specific practice amounts, (b) engagement in various practice contexts, (c) threats to commitment to one's sport, and (d) skill development using the Brief Self-Control Scale (BSCS) in a diverse sport sample. Two hundred forty-four athletes (47% female; M age  = 21.96 years, SD = 6.98 years; 68.8% individual sports and 31.2% team sports; 13.77 [SD = 8.12] hr/week of sport-specific practice) completed a survey composed of the BSCS and practice-related measures. Three skill groups (basic/intermediate, advanced, expert) were informed by athletes' self-reported highest level of competition. Separate analyses were conducted for juniors (aged 12-17 years) and seniors (aged 18-43 years). A 2-factor model (self-discipline and impulse control) fit the BSCS data. Fewer thoughts of quitting from one's sport were associated with higher self-discipline in juniors and seniors and were also related to higher impulse control in seniors. Greater practice amounts were associated with higher self-discipline; however, only seniors showed such associations in voluntary practice contexts. For juniors and seniors, impulse control was associated with more voluntary practicing. There were, however, no skill-group differences for levels of self-discipline or impulse control. Self-discipline and impulse control may be dispositional characteristics associated with how athletes engage in practice and avert conditions that threaten their sport commitment. SC dispositions may relate to practice amounts differently in juniors and seniors, depending on the requirements for self-regulation in a practice context.

    Background Quality indicators determine the quality of actual practice in reference to standard criteria. The Community Pharmacy Association (Thailand), with technical support from the International Pharmaceutical Federation, developed a tool for quality assessment and quality improvement at community pharmacies. This tool has passed validity and reliability tests, but has not yet had feasibility testing. Objective (1) To test whether this quality tool could be used in routine settings. (2) To compare quality scores between accredited independent and accredited chain pharmacies. Setting Accredited independent pharmacies and accredited chain pharmacies in the north eastern region of Thailand. Methods A cross sectional study was conducted in 34 accredited independent pharmacies and accredited chain pharmacies. Quality scores were assessed by observation and by interviewing the responsible pharmacists. Data were collected and analyzed by independent t-test and Mann-Whitney U test as appropriate. Results were plotted by histogram and spider chart. Main outcome measure Domain's assessable scores, possible maximum scores, mean and median of measured scores. Results Domain's assessable scores were close to domain's possible maximum scores. This meant that most indicators could be assessed in most pharmacies. The spider chart revealed that measured scores in the personnel, drug inventory and stocking, and patient satisfaction and health promotion domains of chain pharmacies were significantly higher than those of independent pharmacies (p < 0.05). There was no statistical difference between independent pharmacies and chain pharmacies in the premise and facility or dispensing and patient care domains. Conclusion Quality indicators developed by the Community Pharmacy Association (Thailand) could be used to assess quality of practice in pharmacies in routine settings. It is revealed that the quality scores of chain pharmacies were higher than those of independent pharmacies.

    Obstructive sleep apnea is characterized by intermittent hypoxia and hypercapnia. CO 2 production, transport and elimination are influenced by the carbonic anhydrase enzyme. We hypothesized that elevated standard bicarbonate, a proxy for increased carbonic anhydrase activity, is associated with apnea severity and higher blood pressure in patients with obstructive sleep apnea. A retrospective analysis of a sleep apnea cohort (n = 830) studied by ambulatory polygraphy. Office systolic/diastolic blood pressure, lung function, and arterial blood gases were assessed during daytime. Arterial standard bicarbonate was increased with apnea severity (mild/moderate/severe 24.1 ± 1.8, 24.4 ± 1.7 and 24.9 ± 2.9 mmol/l, respectively, Kruskal-Wallis test p < 0.001). Standard bicarbonate was independently associated with apnea hypopnea index after adjustment for sex, age, body mass index, smoking, alcohol, hypertension, pO 2 and pCO 2 (standard bicarbonate quartile 1 vs. quartile 4, β = 10.6, p < 0.001). Log-transformed standard bicarbonate was associated with a diagnosis of hypertension or diastolic blood pressure but not systolic blood pressure adjusting for cofounders (p = 0.007, 0.048 and 0.45, respectively). There was an independent association between sleep apnea severity and arterial standard bicarbonate. The link between high standard bicarbonate and daytime hypertension suggests that carbonic anhydrase activity may constitute a novel mechanism for blood pressure regulation in sleep apnea.

    The aim of this study was to investigate the association between oral health status and central obesity (CO) in Brazilian independent-living elderly. A cross-sectional study was carried out in a sample of 489 elderly, who were participants of the Study on Aging and Longevity, in Londrina, state of Parana. The number of natural teeth and use of prostheses were evaluated according to the World Health Organization criteria. The presence of CO was assessed using measures of waist circumference (WC) and waist-hip ratio (WHR). Information concerning sociodemographic profile and some systemic conditions was also collected. Data were analyzed using stepwise logistic regression, α=5%. According to WC and WHR measures, the prevalence of central obesity was 79.3% and 76.1%, respectively. CO according to WC was not associated with oral status. Considering the WHR measure, the following oral conditions were associated to CO: having fewer natural teeth (OR = 2.61; 95%CI = 1.17-5.80), being edentulous and wearing both upper and lower complete dentures (OR = 2.34; 95%CI = 1.11-4.93), and being edentulous wearing only the upper complete denture (OR = 2.64; 95%CI = 1.01-6.95). Traditional risk factors for CO such as gender, dyslipidemia, hypertension and diabetes were associated with both measures. A poor oral health due to extensive tooth loss, whether partial or complete, even if rehabilitated by removable prostheses, may be considered a good predictor of CO in Brazilian independent-living elderly.

    Accuracy of phonetic transcription is a core skill for speech and language therapists (SLTs) worldwide (Howard & Heselwood, 2002). The current study investigates the value of weekly independent online phonetic transcription tasks to support development of this skill in year one SLT students. Using a mixed methods observational design, students enrolled in a year one phonetics module completed 10 weekly homework activities in phonetic transcription on a stand-alone tutorial site (WebFon (Bates, Matthews & Eagles, 2010)) and 5 weekly online quizzes (the 'Ulster Set' (Titterington, unpublished)). Student engagement with WebFon was measured in terms of the number of responses made to 'sparks' on the University's Virtual Learning Environment Discussion Board. Measures of phonetic transcription accuracy were obtained for the 'Ulster Set' and for a stand-alone piece of coursework at the end of the module. Qualitative feedback about experience with the online learning was gathered via questionnaire. A positive significant association was found between student engagement with WebFon and performance in the 'Ulster Set', and between performance in the 'Ulster Set' and final coursework. Students valued both online independent learning resources as each supported different learning needs. However, student compliance with WebFon was significantly lower than with the 'Ulster Set'. Motivators and inhibitors to engagement with the online resources were investigated identifying what best maximised engagement. These results indicate that while 'independent' online learning can support development of phonetic transcription skills, the activities must be carefully managed and constructively aligned to assessment providing the level of valance necessary to ensure effective engagement.

    This study examines the independent effects of neighbourhood context (i.e. neighbourhood poverty) and exposure to perceived discrimination in shaping risk of obesity over time. Weighted three-level hierarchical linear regression models for a continuous outcome were used to assess the independent effects of neighbourhood poverty and perceived discrimination on obesity over time in a sample of 157 non-Hispanic Black, non-Hispanic White and Hispanic adults in Detroit, USA, in 2002/2003 and 2007/2008. Independent associations were found between neighbourhood poverty and perceived discrimination with central adiposity over time. Residents of neighbourhoods with high concentrations of poverty were more likely to show increases in central adiposity compared with those in neighbourhoods with lower concentrations of poverty. In models adjusted for BMI, neighbourhood poverty at baseline was associated with a greater change in central adiposity among participants who lived in neighbourhoods in the second (B=3.79, p=0.025) and third (B=3.73, p=0.024) poverty quartiles, compared with those in the lowest poverty neighbourhoods. The results from models that included both neighbourhood poverty and perceived discrimination showed that both were associated with increased risk of increased central adiposity over time. Residents of neighbourhoods in the second (B=9.58, p<0.001), third (B=8.25, p=0.004) and fourth (B=7.66, p=0.030) quartiles of poverty were more likely to show greater increases in central adiposity over time, compared with those in the lowest poverty quartile, with mean discrimination at baseline independently and positively associated with increases in central adiposity over time (B=2.36, p=0.020). The results suggest that neighbourhood poverty and perceived discrimination are independently associated with a heightened risk of increase in central adiposity over time. Efforts to address persistent disparities in central adiposity in the USA should include strategies to

    Hippocampal injury in the Alzheimer's disease (AD) pathological process is region-specific and magnetic resonance imaging (MRI)-based measures of localized hippocampus (HP) atrophy are known to detect region-specific changes associated with clinical AD, but it is unclear whether these measures provide information that is independent of that already provided by measures of total HP volume. Therefore, this study assessed the strength of association between localized HP atrophy measures and AD-related measures including cerebrospinal fluid (CSF) amyloid beta and tau concentrations, and cognitive performance, in statistical models that also included total HP volume as a covariate. A computational technique termed localized components analysis (LoCA) was used to identify 7 independent patterns of HP atrophy among 390 semiautomatically delineated HP from baseline magnetic resonance imaging of participants in the Alzheimer's Disease Neuroimaging Initiative (ADNI). Among cognitively normal participants, multiple measures of localized HP atrophy were significantly associated with CSF amyloid concentration, while total HP volume was not. In addition, among all participants, localized HP atrophy measures and total HP volume were both independently and additively associated with CSF tau concentration, performance on numerous neuropsychological tests, and discrimination between normal, mild cognitive impairment (MCI), and AD clinical diagnostic groups. Together, these results suggest that regional measures of hippocampal atrophy provided by localized components analysis may be more sensitive than total HP volume to the effects of AD pathology burden among cognitively normal individuals and may provide information about HP regions whose deficits may have especially profound cognitive consequences throughout the AD clinical course.

  13. Knowing Your Limits: A Qualitative Study of Physician and Nurse Practitioner Perspectives on NP Independence in Primary Care.

    2017-03-01

    The shortage of primary care providers and the provisions of the Affordable Care Act (ACA) have spurred discussion about expanding the number, scope of practice (SOP), and independence of primary care nurse practitioners (NPs). Such discussions in the media and among professional organizations may insinuate that changes to the laws governing NP practice will engender acrimony between practicing physicians and NPs. However, we lack empirical, descriptive data on how practicing professionals view NP independence in primary care. The aim of the present study was to explore and describe the attitudes about NP independence among physicians and NPs working in primary care. A qualitative study based on the principles of grounded theory. Thirty primary care professionals in Missouri, USA, including 15 primary care physicians and 15 primary care NPs. Semi-structured, in-depth interviews, with data analysis guided by grounded theory. Participants had perspectives that were not well represented by professional organizations or the media. Physicians were supportive of a wide variety of NP roles and comfortable with high levels of NP independence and autonomy. Physicians and NPs described prerequisites to NP independence that were complementary. Physicians generally believed that NPs needed some association with physicians for patient safety, and NPs preferred having a physician readily accessible as needed. The theme "knowing your limits" was important to both NPs and physicians regarding NP independence, and has not been described previously in the literature. NP and physician views about NP practice in primary care are not as divergent as their representative professional organizations and the news media would suggest. The significant agreement among NPs and physicians, and some of the nuances of their perspectives, supports recommendations that may reduce the perceived acrimony surrounding discussions of NP independent practice in primary care.

  14. Employee (Dis)Engagement: Learning from Nurses Who Left Organizational Jobs for Independent Practice.

    Employee engagement is of growing interest in healthcare organizations. Engaged employees give an extra measure of effort to contribute to organization goals, whereas disengaged employees withdraw, have lower performance and are more likely to leave their jobs. The aim of this ethnographic study was, in part, to explore the reasons why high-calibre nurses became disengaged from their work and opted to leave their hospital-based employment in favour of independent practice, as well as to consider the organizational conditions that influenced their desire to leave. The findings revealed that nurses left their hospital-based jobs because of health system change, job characteristics, working conditions and lack of respect, which relate closely to the antecedents of employee engagement. Employee engagement can be fostered through organizational support, trust-building management behaviour and transformational leadership. Copyright © 2015 Longwoods Publishing.

  15. Interesting Times: Practice, Science, and Professional Associations in Behavior Analysis

    Neither practitioners nor scientists appear to be fully satisfied with the world's largest behavior-analytic membership organization. Each community appears to believe that initiatives that serve the other will undermine the association's capacity to serve their own needs. Historical examples suggest that such discord is predicted when practitioners and scientists cohabit the same association. This is true because all professional associations exist to address guild interests, and practice and science are different professions with different guild interests. No association, therefore, can succeed in being all things to all people. The solution is to assure that practice and science communities are well served by separate professional associations. I comment briefly on how this outcome might be promoted. PMID:22532750

  16. Factors associated with different hygiene practices in the homes of 15 month old infants

    Sherriff, A; Golding, J; The, A

    2002-01-01

    Background: Improved hygiene in Westernised regions of the world may be partly responsible for the increased prevalence of diseases of the immune system, such as asthma and atopy. There is a paucity of data on cleanliness norms in young children in the UK and there has been no attempt to identify factors that influence the adoption of particular hygiene practices in the home. Aims: To examine levels of hygiene in a contemporary cohort of children and identify social and lifestyle factors influencing hygiene practices in the home. Methods: The sample under study are participants in the Avon Longitudinal Study of Parents and Children (ALSPAC). Parental self completion questionnaires provided data on hygiene levels in children at 15 months of age, and a hygiene score was derived from these responses. Multivariable logistic regression models investigated associations between high hygiene scores (top quintile) and a number of perinatal, maternal, social, and environmental factors. Results: Maternal smoking during pregnancy, low maternal educational achievement, and living in local authority housing were factors independently associated with high hygiene scores, as was increased use of chemical household products. High hygiene scores were inversely related to living in damp housing and attendance at day care. There were no gender or ethnic differences in hygiene score. Conclusion: Important data on cleanliness norms for infants have been presented. The adoption of hygiene practices is influenced to some degree by social, lifestyle, and environmental factors—with higher hygiene scores occurring in more socially disadvantaged groups. Increased use of chemical household products in the more socially disadvantaged groups within ALSPAC has emerged as an important confounder in any study of hygiene and ill health. PMID:12089118

    2015-04-01

    Oregon allows dental hygienists to provide services without the supervision of a dentist if they hold an expanded practice permit (EPP). This study surveyed practicing and non-practicing EPP holders with the purpose of assessing perceived barriers to practicing independently and better educating students to begin independent practice upon graduation. A survey was developed, approved by the institutional review board and pilot tested with current Expanded Practice Dental Hygienists (EPDHs). A list of EPDHs was obtained from the Oregon State Dental Board, and 181 surveys were mailed in November 2011. The response rate was 39% (n=71). Data from this study indicate a large number of new EPP holders, with 62% (n=41) holding their permit for 3 years or less, but only 41% (n=29) of respondents are actually providing care in a setting requiring an EPP. Responding practicing EPDHs reported barriers including: challenges with insurance reimbursement, lack of knowledge/acceptance, equipment cost/maintenance, difficulty obtaining a collaborative agreement/cooperating facility, advertising and inability to make a living wage. Responding non-practicing EPDHs reported barriers including: currently working in another setting, lack of business knowledge, time, start-up cost, inability to make a living wage, lack of opportunity, reimbursement difficulties and lack of experience. Perceived barriers to practicing independently differ between those practicing utilizing their EPP and those not practicing. Ways to eliminate barriers for both practicing and non-practicing EPDHs should be explored. There is potential to reduce the barriers to independent practice through curricular changes, public health partnerships among EPDHs, and new health care systems that specifically address barriers found through this study.

    While various methods for long-term archiving of nuclear medicine image data exist, none support rapid on-line search and retrieval of information. We assembled a 90-Gbyte redundant array of independent disks (RAID) system using 10-, 9-Gbyte disk drives. The system was connected to a personal computer and software was used to partition the array into 4-Gbyte sections. All studies (50,000) acquired over a 7-year period were archived in the system. Based on patient name/number and study date, information could be located within 20 seconds and retrieved for display and analysis in less than 5 seconds. RAID offers a practical, redundant method for long-term archiving of nuclear medicine studies that supports rapid on-line retrieval.

  19. Utilization of the American Telemedicine Association's Clinical Practice Guidelines

    Antoniotti, Nina; Bernard, Jordana

    2013-01-01

    Abstract Background: The American Telemedicine Association (ATA) Standards and Guidelines Committee develops practice standards and guidelines. Key to the Committee's mission is dissemination so the standards can be used in the practice of telemedicine. Over a 2-year period, when a standards document was accessed from the ATA Web site, a short survey was completed, but it did not assess how the documents were used once downloaded. A more formal survey was conducted to determine the impact ATA standards and guidelines are having on healthcare delivery via telemedicine. Materials and Methods: A survey was developed and distributed via SurveyMonkey to 13,177 ATA members and nonmembers in November 2011. Results were compiled and analyzed after a 90-day open period for responses to be submitted. Results: The majority of respondents (96%) believe the practice of telemedicine/telehealth should have standards and guidelines and that the ATA and other professional societies/associations should be responsible for developing them. The top uses of guidelines include guidance for clinical practice, training, gaining reimbursement, and research. Respondents indicating a need for standards and guidelines said the ATA (78.7%) and other professional societies/associations (74.5%) should be responsible for development. When asked to list specific practice guidelines or standards they are using for telehealth, the majority (21.5%) are using in-house (e.g., hospital, company)-developed guidelines, followed by those from professional associations/societies (20.4%) and those developed by the ATA (18.2%). Conclusions: Overall, the survey results indicate guidelines documents developed by the ATA and other professional societies and those developed in-house are being regularly accessed and used in both public and private sectors. Practitioners of telemedicine believe that standards and guidelines are needed for guidance for clinical practice, training, gaining reimbursement, and research

  20. Scope-of-practice laws for nurse practitioners limit cost savings that can be achieved in retail clinics.

    Retail clinics have the potential to reduce health spending by offering convenient, low-cost access to basic health care services. Retail clinics are often staffed by nurse practitioners (NPs), whose services are regulated by state scope-of-practice regulations. By limiting NPs' work scope, restrictive regulations could affect possible cost savings. Using multistate insurance claims data from 2004-07, a period in which many retail clinics opened, we analyzed whether the cost per episode associated with the use of retail clinics was lower in states where NPs are allowed to practice independently and to prescribe independently. We also examined whether retail clinic use and scope of practice were associated with emergency department visits and hospitalizations. We found that visits to retail clinics were associated with lower costs per episode, compared to episodes of care that did not begin with a retail clinic visit, and the costs were even lower when NPs practiced independently. Eliminating restrictions on NPs' scope of practice could have a large impact on the cost savings that can be achieved by retail clinics.

    Background and Aim: Patients with chronic kidney disease (CKD) often have subclinical hypothyroidism. However, few reports have investigated changes in the status of subclinical hypothyroidism in CKD patients and its clinical significance in CKD progression. Methods: We included 168 patients with nondialysis-dependent CKD stages 2-4. The normalization of subclinical hypothyroidism during follow-up was assessed, and the association between transitions in subclinical hypothyroid status and the rate of decline of the estimated glomerular filtration rate (eGFR) was investigated. Results: At baseline, 127 patients were euthyroid and 41 (24.4%) patients were diagnosed with subclinical hypothyroidism. Of these 41 patients, 21 (51.2%) spontaneously resolved to euthyroid during follow-up. The rate of eGFR decline of patients with resolved subclinical hypothyroidism was similar to that of euthyroid patients. The patients with unresolved subclinical hypothyroidism showed a steeper renal function decline than patients with euthyroidism or resolved subclinical hypothyroidism (all p < 0.05). The progression to end-stage renal disease was more frequent in those with unresolved subclinical hypothyroidism than in those who were euthyroid (p = 0.006). In multivariate linear regression for rate of eGFR decrease, unresolved subclinical hypothyroidism (β = -5.77, p = 0.001), baseline renal function (β = -0.12, p < 0.001) and level of proteinuria (β = -2.36, p = 0.015) were independently associated with the rate of renal function decline. Conclusions: Half of the CKD patients with subclinical hypothyroidism did not resolve to euthyroidism, and this lack of resolution was independently associated with rapid renal function decline.

  2. Managing money matters: Managing finances is associated with functional independence in MCI.

    Previous research suggests that overall experience participating in instrumental activities of daily living (IADLs) is associated with reduced IADL impairment in individuals with mild cognitive impairment, possibly because of an increased functional reserve. Given that difficulties managing finances tend to occur with mild cognitive impairment, this study explores whether experience managing one's finances is associated with independence across various IADLs. Participants with a screen or baseline diagnosis of mild cognitive impairment (n = 862) were taken from the Alzheimer's Disease Neuroimaging Initiative study. Functional dependence and experience were quantified from the Functional Activities Questionnaire. No group differences between those with and without financial management experience existed in Mini-Mental State Examination scores, age, and years of education, although women were more likely to have experience managing finances (P < .001). Final chi-square analyses suggest that financial management experience is significantly associated with greater independence in the ability to follow TV, books, or magazines (P = .009) and remember appointments and important dates (P = .002). Individuals who are rated as having experience in managing their finances were also rated as being less dependent in their ability to follow and understand TV and books and in their ability to remember appointments and important dates. Neither causation nor the mechanisms underlying this relationship can be discerned from these analyses. Therefore, further research is needed to investigate whether engaging in financial tasks protects against early financial impairment, potentially through an increased functional reserve.

    There are at least two different etio-pathogenic pathways for the development of vulvar squamous cell carcinoma (VSCC): one associated with infection by human papillomavirus (HPV) and another independent of HPV. We aimed to describe the histological characteristics of HPV-associated and -independent tumors and to determine the best strategy to identify HPV in VSCC. A single paraffin block was available for review from a series of 1,594 VSCCs. In all cases HPV DNA detection was analyzed using the SPF10PCR/DEIA/LiPA25 system and p16 immunohistochemistry (IHC). A tumor was considered as unquestionably HPV-associated if both HPV DNA and p16 IHC were positive. A tumor was considered indisputably HPV-independent if both HPV DNA and p16 IHC were negative. Two groups of tumors were classified as non-conclusive: (1) HPV DNA+/p16- and (2) HPV DNA-/p16+. WHO typing and a thorough histological evaluation were conducted in all cases. Four hundred and forty-one tumors were HPV DNA+ with 367 cases (23.0%) being HPV DNA+/p16+. The latter tumors were more frequently basaloid or warty (49.8%), but 36.5% were of the keratinizing type; 1,153 tumors were HPV DNA-, with 1,060 cases (66.5%) being HPV DNA-/p16-. These HPV DNA-/p16- tumors were mostly keratinizing (81.2%) but were occasionally basaloid or warty (5.2%). The features of HPV DNA-/p16+ cases (n = 93) were similar to those of the HPV-associated VSCC, and HPV DNA+/p16- (n = 74) cases had a more diverse profile, although they were more similar to HPV-independent tumors. Several histological characteristics were more frequently associated with HPV-related VSCC (koilocytotic-like change, necrosis, moderate to marked pleomorphism, invasive front in nests; p < 0.001), however, none of these characteristics allowed differentiation between HPV-associated and -independent VSCC. In conclusion, histological criteria do not allow differentiation between HPV-associated and -independent VSCC. p16 Alone is a clinically easy

    The purpose of this study was to look at the determinants of the unsteady walking (UW) symptom in patients with type 2 diabetes mellitus (T2DM) by defining if UW and/or the Diabetic Neuropathy Symptoms Score (DNSS) are associated with positive scores in Beck's Depression Inventory (BDI) and with a positive Michigan Neuropathy Screening Instrument score (MNSI). We evaluated 203 T2DM patients without visible gait disturbances. They were divided into UW (+) and UW (-) or DNSS (+) and DNSS (-) according to symptoms. We found a prevalence of 48.3% for UW (+) and of 63% for DNSS (+) in our sample. In univariate analysis, the presence of UW was significantly associated with waist circumference (P=0.024), number of comorbidities (P=0.012), not practicing physical exercise (P=0.011), positive BDI score (P=0.003), presence of neuropathic symptoms by the MNSI questionnaire (P<0.001), and positive diabetic neuropathy screening by MNSI (P=0.021). In multivariate analysis, UW (used as a dependent variable) was independently associated with a positive BDI score (P<0.001; 95%CI=1.01-1.03), T2DM duration (P=0.023; 95%CI=1.00-1.03), number of co-morbidities (P=0.032; 95%CI=1.01-1.37), and a sedentary lifestyle (P=0.025; 95%CI=1.06-2.5). The UW symptom and a positive DNSS are more closely related to a positive score for depression than to presence of neuropathy in T2DM.

    The present study examined the pattern of associations among physical activity, social support, mobility disability, perceived stress, and depressive symptoms in relapsing-remitting MS (RRMS). Persons (N = 218) with RRMS completed a battery of questionnaires that was sent and returned through the United States Postal Service (USPS). Bivariate correlation analysis indicated that physical activity and social support were both inversely associated with depressive symptoms (r's = -0.288 and -0.386, p ≤ 0.05, respectively). Multiple linear regression analysis indicated that physical activity (β = -0.21, p = 0.002) and social support (β = -0.37, p = 0.0001) were independently associated with depressive symptoms. Path analysis confirmed that the associations between physical activity and social support with depressive symptoms were indirect via mobility disability and perceived stress. Collectively, the evidence indicates that physical activity and social support are independently and indirectly associated with depression via mobility disability and perceived stress in relapsing-remitting MS. This supports the design of interventions and programs that target physical activity and social support for reducing depressive symptoms among persons with MS.

With respect to critical driving errors, 55% of teens committed a total of 85 critical errors (range of 1-5 errors per driver) on the early tODA; by comparison, only one adult committed a critical error (p<0.001). On the late tODA, 54% of teens committed 67 critical errors (range of 1-8 errors per driver) compared with only one adult (p<0.001). No differences in teen or parent gender, parent/teen relationship type or parent prior experience teaching a teen to drive were observed between teens who committed a critical error on either route and teens that committed no critical errors. A borderline association between median teen-reported practice quantity and critical error commission was observed for the late tODA. The overall median proportion of vehicle operation errors for teens was higher than that of adults on both assessments, though median error proportions were less than 10% for both teens and adults. In comparison to a group of experienced adult drivers, a substantially higher proportion of learner teens committed safety-relevant critical driving errors at both time points of assessment. These findings, as well as the associations between practice quantity and the driving performance outcomes studied suggest that further research is needed to better understand how teens might effectively learn skills necessary for safe independent driving while they are still under supervised conditions.

    Background Bundles and checklists have been shown to decrease CLABSIs, but implementation of these practices and association with CLABSI rates have not been described nationally. We describe implementation and levels of compliance with prevention practices in a sample of US Neonatal ICUs and assess their association with CLABSI rates. Methods An online survey assessing infection prevention practices was sent to hospitals participating in National Healthcare Safety Network CLABSI surveillance in October 2011. Participating hospitals permitted access to their NICU CLABSI rates. Multivariable regressions were used to test the association between compliance with NICU specific CLABSI prevention practices and corresponding CLABSI rates. Results Overall, 190 Level II/III and Level III NICUs participated. The majority of NICUs had written policies (84%-93%) and monitored compliance with bundles and checklists (88% - 91%). Reporting ≥ 95% compliance for any of the practices ranged from 50%- 63%. Reporting ≥ 95% compliance with insertion checklist and assessment of daily line necessity were significantly associated with lower CLABSI rates (p<0.05). Conclusions Most NICUs in this national sample have instituted CLABSI prevention policies and monitor compliance, although reporting compliance ≥ 95% was suboptimal. Reporting ≥ 95% compliance with select CLABSI prevention practices was associated with lower CLABSI rates. Further studies should focus on identifying and improving compliance with effective CLABSI prevention practices in neonates. PMID:25087136

    This study examined the relationship between scores on field dependence and field independence and sensory learning preference, cognitive learning style, personality, interpersonal trust, attributions of responsibility for solving social problems, and attitudes regarding citizenship among youth. Participants were 72 private school students in Grades 6 through 12 (26 girls, 46 boys; M age: 15.2 yr., SD=1.9). When controlling for grade and sex, field independence (measured by Group Embedded Figures Test scores) was associated with Intuitive Thinking personality, Concrete lobal learning style, and rejection of individual responsibility for social problems, relative to governmental and community responsibility. Associations with other aspects of learning style fell short of significance. No association was found with generalized trust or citizenship attitudes. Reassessment of these variables with a larger sample should be undertaken.

    Results associating dairy and Ca intakes with colorectal cancer (CRC) risk have been mixed. Most previous analyses have suffered from confounding between dairy and Ca intakes. We examined independent associations between these variables, also dairy foods, and CRC incidence in a population with a large range of dairy intakes. Adventist Health Study-2 is a cohort study where subjects were enrolled 2002-2007. Proportional hazard regression analyses were performed to estimate hazard ratios (HR). Regression calibration was used to correct for dietary measurement error. The population lived in all states of the USA. There were 77712 analytic subjects, all of whom were Seventh-day Adventists. Much of their dietary Ca came from non-dairy sources. During a mean follow-up of 7·8 years, 380 incident colon cancer and 111 incident rectal cancer cases were observed. Comparing extreme quintiles of intake in measurement error-corrected analyses, dairy intake (HR=0·31; 95 % CI 0·09, 0·88), independent of total Ca, was inversely related with risk of rectal cancer but gave little indication of association with colon cancer. However, total Ca intake (independent of dairy) was associated with risk of colon cancer (HR=0·55; 95 % CI 0·28, 0·98) and there was little indication of association with rectal cancer. Traditional regression analyses and associations with macronutrients from dairy generally supported these results. Milk intake was also negatively associated with CRC (HR=0·63; 95 % CI 0·43, 0·89). Dairy intake may decrease the risk of rectal cancer, and Ca may reduce risk of colon cancer and CRC.

    Objective Medication-overuse headache is often comorbid with emotional disturbances and disordered personality traits. The aim of the present study was to determine whether depression and insomnia complaints were associated with satisfaction and enjoyment with one's own life in medication-overuse headache patients, and whether insomnia complaints were able to explain part of the variance of Quality of Life explained by depression. Methods Participants were 187 consecutive adult outpatients admitted to the Regional Referral Headache Centre of the Sant'Andrea Hospital in Rome, Italy. Patients were administered the Quality of Life Enjoyment and Satisfaction Questionnaire, the Beck Depression Inventory - II, and the Athens Insomnia Scale. Results The Beck Depression Inventory was associated with all the dimensions of the Quality of Life Enjoyment and Satisfaction Questionnaire, with more severe depression being associated independently with lower satisfaction and enjoyment with one's own life. The Athens Insomnia Scale was independently and significantly associated only with physical health, such that patients with more insomnia complaints were 3.1 times ( p < 0.001) more likely to report lower physical health satisfaction. Conclusions Our findings confirmed that medication-overuse headache patients has a negative impact on quality of life and suggested that depression and insomnia were independently associated with satisfaction and enjoyment of life in medication-overuse headache patients. The early recognition and appropriate treatment of comorbid psychopathological symptoms are crucial to improve satisfaction and enjoyment of life in medication-overuse headache patients.

    Introduction The dilemma posed between lifesaving benefit and risk of transmission through breast feeding complicates infant feedings among communities grossly affected by HIV/AIDS. According to the world health organization’s guideline which was revised in 2010, exclusive breast feeding and exclusive replacement feeding are the recommended infant feeding practices for HIV positive mothers. The aim of this study was to assess infant feeding practice and associated factors among HIV positive mothers in Debre Markos Referral Hospital, North West Ethiopia. Methods An institutional based cross sectional study was conducted from May to September 2013. A Randomly selected 260 HIV positive mothers were included. The data were collected by using a pretested and structured questionnaire. Bivariate and multivariate analysis were performed to check association and to control confounders. Results From a total of 260 HIV positive mothers, 85.8% of them were feeding their children based on the recommended feeding way of infant feeding practice with the remaining percentage 14.2% were practicing mixed feeding. In multivariate analysis mothers attending high school and above AOR = 5.3 [95% CI = 1.25-22.1], having antenatal care follow up AOR = 5.5 [95% CI = 1.5-20.16], being on anti-retro viral therapy AOR = 6.5 [95% CI = 1.88-22.51] and disclosure of HIV status AOR = 7.1 [95% CI = 1.26-39.76] were found to be independently associated with infant feeding practice. Conclusion This study revealed that large proportion of HIV positive mothers had followed the recommended infant feeding practice and significantly high number of mothers had practiced mixed feeding. Educating mothers, increasing ANC utilization, counseling mothers to start ART, encouraging and supporting mothers to disclose their HIV status were recommended. PMID:28154655

    Despite research linking family meals to healthier diets, some families are unable to have regular meals together. These families need guidance about other ways to promote healthy eating among adolescents. Our aim was to examine the association between various parenting practices and adolescent fruit and vegetable (F/V) intake at different levels of family meal frequency. We conducted a cross-sectional, population-based survey of influences on adolescent weight-related behaviors using Project EAT (Eating and Activity in Teens) 2010. Participants were 2,491 adolescents recruited from middle/high schools in Minneapolis/St Paul, MN. Adolescent F/V intake was ascertained with a food frequency questionnaire. Survey items assessed frequency of family meals and F/V parenting practices (availability, accessibility, parent modeling, parent encouragement, and family communication). Linear regression models were used to examine associations with and interactions among family meals and parenting practices. Models were adjusted for age, sex, socioeconomic status, race/ethnicity, and energy intake (kilocalories per day). Family meals, F/V availability, F/V accessibility, F/V modeling, and encouragement to eat healthy foods were independently associated with higher F/V intake. Of the 949 (34%) adolescents who reported infrequent family meals (≤2 days/wk), mean F/V intake was 3.6 servings/day for those with high home F/V availability vs 3.0 servings/day for those with low home F/V availability. Similar differences in mean F/V intake (0.3 to 0.6 servings/day) were found for high vs low F/V accessibility, parental modeling, and parent encouragement for healthy eating. Frequent family meals in addition to more favorable parenting practices were associated with the highest F/V intakes. Food parenting practices and family meals are associated with greater adolescent F/V intake. Longitudinal and intervention studies are needed to determine which combination of parenting practices

    Background The aim of this study was to identify factors associated with cancer screening practices and with general attitudes toward cancer screening in a general population. Methods Mailed survey of 30–60 year old residents of Geneva, Switzerland, that included questions about screening for five cancers (breast, cervix uteri, prostate, colon, skin) in the past 3 years, attitudes toward screening, health care use, preventive behaviours and socio-demographic characteristics. Cancer screening practice was dichotomised as having done at least one screening test in the past 3 years versus none. Results The survey response rate was 49.3% (2301/4670). More women than men had had at least one cancer screening test in the past 3 years (83.2% vs 34.5%, p < 0.001). A majority of women had had a cervical smear (76.6%) and a mammography (age 30–49: 35.0%; age 50 and older: 90.3%); and 55.1% of men 50–60 years old had been screened for prostate cancer. Other factors associated with screening included older age, higher income, a doctor visit in the past 6 months, reporting a greater number of preventive behaviours and a positive attitude toward screening. Factors linked with positive attitudes included female gender, higher level of education, gainful employment, higher income, a doctor visit in the past 6 months and a personal history of cancer. Conclusion Attitudes play an important role in cancer screening practices among middle-aged adults in the general population, independent of demographic variables (age and sex) that determine in part screening recommendations. Negative attitudes were the most frequent among men and the most socio-economically disadvantaged. The moderate participation rate raises the possibility of selection bias. PMID:19402895

    Recent proposals to reform primary care have encouraged physician practices to adopt such structural capabilities as performance feedback and electronic health records. Whether practices with these capabilities have higher performance on measures of primary care quality is unknown. To measure associations between structural capabilities of primary care practices and performance on commonly used quality measures. Cross-sectional analysis. Massachusetts. 412 primary care practices. During 2007, 1 physician from each participating primary care practice (median size, 4 physicians) was surveyed about structural capabilities of the practice (responses representing 308 practices were obtained). Data on practice structural capabilities were linked to multipayer performance data on 13 Healthcare Effectiveness Data and Information Set (HEDIS) process measures in 4 clinical areas: screening, diabetes, depression, and overuse. Frequently used multifunctional electronic health records were associated with higher performance on 5 HEDIS measures (3 in screening and 2 in diabetes), with statistically significant differences in performance ranging from 3.1 to 7.6 percentage points. Frequent meetings to discuss quality were associated with higher performance on 3 measures of diabetes care (differences ranging from 2.3 to 3.1 percentage points). Physician awareness of patient experience ratings was associated with higher performance on screening for breast cancer and cervical cancer (1.9 and 2.2 percentage points, respectively). No other structural capabilities were associated with performance on more than 1 measure. No capabilities were associated with performance on depression care or overuse. Structural capabilities of primary care practices were assessed by physician survey. Among the investigated structural capabilities of primary care practices, electronic health records were associated with higher performance across multiple HEDIS measures.

    Associations of socioeconomic status (SES) with the prevalence of various forms of arthritis are well documented. Increasing evidence suggests that SES during childhood is a lasting determinant of health, but its association with the onset of arthritis remains unclear. Cross-sectional data on 1276 participants originated from 22 family practices in North-Carolina, USA. We created 4-level (high, medium, low, lowest) current SES and childhood SES summary scores based on parental and participant education, occupation and homeownership. We investigated associations of individual SES characteristics, summary scores and SES trajectories (e.g. high/low) with self-reported arthritis in logistic regression models progressively adjusted for race and gender, age, then BMI, and clustered by family practice. We found evidence for independent associations of both childhood and current SES with the reporting of arthritis across our models. In covariate-adjusted models simultaneously including current and childhood SES, compared with high SES participants in the lowest childhood SES category (OR = 1.39 [95% CI = 1.04, 1.85]) and those in the low (OR = 1.66 [95% CI = 1.14, 2.42]) and lowest (OR = 2.08 [95% CI = 1.16, 3.74]) categories of current SES had significantly greater odds of having self-reported arthritis. Current SES and childhood SES are both associated with the odds of reporting arthritis within this primary-care population, although the possibly superseding influence of existing circumstances must be noted. BMI was a likely mechanism in the association of childhood SES with arthritis onset, and research is needed to elucidate further pathways linking the socioeconomic environment across life-stages and the development of rheumatic diseases.

    Determinants of cardiomyocyte injury as quantified by high-sensitivity cardiac troponin I (cTnI) in young and healthy individuals, and sex-specific 99th percentiles are largely unknown. Our study included 2077 adults from the general population aged 25-41 years without cardiovascular disease. cTnI was measured using a high-sensitivity assay. We performed stepwise backward linear regression analyses to identify variables independently associated with hs-cTnI levels, and calculated narrow-sense heritability from 1638-genotyped participants. Median age was 37 years. cTnI was quantifiable in all but 11 participants (99.5 %). Median (interquartile range) cTnI was significantly higher in men than in women [0.99 (0.71; 1.65) versus 0.47 (0.33; 0.71) ng/L, p < 0.0001]. The 99th percentile of cTnI was 15.79 ng/L in men and 5.11 ng/L in women. Out of 46 variables, 22 independent determinants for cTnI were identified. The strongest associations were observed with sex, age, systolic blood pressure, heart rate, left ventricular mass, N-terminal pro B-type natriuretic peptide, and creatine kinase (all p < 0.0001). The final model explained 36 % of the overall cTnI variability. Heritability of cTnI was estimated to be 29 % (p = 0.005), but became non-significant when the residuals of the multivariable model were used for analysis (5 %, p = 0.36). Sex, age, and systolic blood pressure belong to the strongest determinants of hs-cTnI in healthy adults. The 99th percentile was three times higher in men compared to women. Hence, sex-specific cut-off values may be preferable when applying hs-cTnI for screening purposes. Our results may also improve the interpretation of cTn levels in daily clinical practice.

    A survey based on postal questionnaire was carried out in France in Spring 2006 among a sample of 4100 independent professionals from 8 occupations: architects, lawyers, notaries, physicians, dentists, biologists, accountants and sellers of insurance contracts. The objective of the survey is to assess the pool of new jobs which may be created by the independent professionals whose the number in France is approximatively 550000 (total population of France in early 2006 : 62.9 millions). Legally and financially, an independent professional can conduct his business in his own office or within a society gathering several professionals. In the first case (called "solo practice") he may be helped by salaried employees and, recently by other professionals who act as associates. In the second case (called "society practice") he is one of the partners of the society which has generally one or several salaried employees. After the answers gathered by the survey, the number of jobs that the professionals envisage to create during one year is rather important. In the low variant, it is estimated 165200 posts, in the high variant, it may reach 226000 posts. These numbers include salaried employees and professional associates. They cover newly created posts and vacant posts filled in by newcomers. In other words, every 100 French independent professionals plan to create during the coming year between 30 and 41 jobs.

    The bacterial communities associated with rotifers (Brachionus plicatilis sp. complex) and their culture water were determined using culture-dependent and -independent methods (16S rRNA gene clone library). The bacterial communities determined by the culture-independent method were more diverse than those determined by the culture-dependent method. Although the culture-dependent method indicated the bacterial community of rotifers was relatively similar to that of the culture water, 16S rRNA gene clone library analyses revealed a great difference between the two microbiotas. Our results suggest that most bacteria associated with rotifers are not easily cultured using conventional methods, and that the microbiota of rotifers do not correspond with that of the culture water completely.

    Data regarding knowledge acquisition during residency training are sparse. Predictors of theoretical learning quality, academic career achievements and evidence-based medical practice during residency are unknown. We performed a cross-sectional study on residents and attending physicians across several residency programs in 2 French faculties of medicine. We comprehensively evaluated the information-seeking behavior (I-SB) during residency using a standardized questionnaire and looked for independent predictors of theoretical learning quality, academic career achievements, and evidence-based medical practice among I-SB components using multivariate logistic regression analysis. Between February 2013 and May 2013, 338 fellows and attending physicians were included in the study. Textbooks and international medical journals were reported to be used on a regular basis by 24% and 57% of the respondents, respectively. Among the respondents, 47% refer systematically (4.4%) or frequently (42.6%) to published guidelines from scientific societies upon their publication. The median self-reported theoretical learning quality score was 5/10 (interquartile range, 3-6; range, 1-10). A high theoretical learning quality score (upper quartile) was independently and strongly associated with the following I-SB components: systematic reading of clinical guidelines upon their publication (odds ratio [OR], 5.55; 95% confidence interval [CI], 1.77-17.44); having access to a library that offers the leading textbooks of the specialty in the medical department (OR, 2.45, 95% CI, 1.33-4.52); knowledge of the specialty leading textbooks (OR, 2.12; 95% CI, 1.09-4.10); and PubMed search skill score ≥5/10 (OR, 1.94; 95% CI, 1.01-3.73). Research Master (M2) and/or PhD thesis enrolment were independently and strongly associated with the following predictors: PubMed search skill score ≥5/10 (OR, 4.10; 95% CI, 1.46-11.53); knowledge of the leading medical journals of the specialty (OR, 3.33; 95

    To determine the association between synaptic functioning as measured via neurogranin in CSF and cognition relative to established Alzheimer disease (AD) biomarkers in neurologically healthy older adults. We analyzed CSF concentrations of neurogranin, β-amyloid (Aβ42), phosphorylated tau (p-tau), and total tau (t-tau) among 132 neurologically normal older adults (mean 64.5, range 55-85), along with bilateral hippocampal volumes and a measure of episodic memory (Auditory Verbal Learning Test, delayed recall). Univariable analyses examined the relationship between neurogranin and the other AD-related biomarkers. Multivariable regression models examined the relationship between neurogranin and delayed recall, adjusting for age and sex, and interaction terms (neurogranin × AD biomarkers). Higher neurogranin concentrations were associated with older age (ρ = 0.20, p = 0.02), lower levels of p-tau and t-tau, and smaller hippocampal volumes ( p < 0.03), but not with CSF Aβ42 ( p = 0.18). In addition, CSF neurogranin demonstrated a significant relationship with memory performance independent of the AD-related biomarkers; individuals with the lowest CSF neurogranin concentrations performed better on delayed recall than those with medium or high CSF neurogranin concentrations ( p < 0.01). Notably, CSF p-tau, t-tau, and Aβ42 and hippocampal volumes were not significantly associated with delayed recall scores ( p > 0.40), and did not interact with neurogranin to predict memory ( p > 0.10). Synaptic dysfunction (assessed via neurogranin) may be an early pathologic process in age-related neurodegeneration, and a sensitive marker of age-related cognitive abilities, potentially preceding or even acting independently from AD pathogenesis. Synaptic functioning may be a useful early marker of cognitive aging and possibly a target for future brain aging interventions. © 2017 American Academy of Neurology.

    Although the prevalence of metabolic syndrome (MetS) has increased in youth, the potential independent contribution of cardiorespiratory fitness (CRF) to the clustering of metabolic risk factors has received relatively little attention. This study evaluated associations between the clustering of metabolic risk factors and CRF in a sample of youth. Height, weight, BMI, fasting glucose, insulin, HDL-cholesterol, triglycerides and blood pressures were measured in a cross-sectional sample of 924 youth (402 males, 522 females) of 11-17 years. CRF was assessed using the 20-metre shuttle run test. Physical activity (PA) was measured with a 3-day diary. Outcome variables were statistically normalized and expressed as Z-scores. A MetS risk score was computed as the mean of the Z-scores. Multiple linear regression was used to test associations between CRF and metabolic risk, adjusted for age, sex, BMI, PA and parental education. CRF was inversely associated with MetS after adjustment for potential confounders. After adjusting for BMI, the relationship between CRF and metabolic risk has substantially improved. CRF was independently associated with the clustering of metabolic risk factors in youth of 11-17 years of age.

    Patients with non-traumatic rupture of an aneurysm located at the anterior communicating artery (ACoA) often experience cognitive disabilities. It is unknown whether location of aneurysm also affects the possibility for improvement in functional independence compared to patients with an aneurysmal subarachnoid hemorrhage (a-SAH) located elsewhere. The aim was to explore the association between location of aneurysm (ACoA versus other) and level of functional independence, measured by Functional Independence Measure (FIM), at discharge from rehabilitation. Additionally, age and FIM at admission were explored. Historical cohort study among 107 patients with a-SAH based on data from a clinical database and a population-based register. Data were analyzed using multivariable logistic regression. Patients with ACoA were admitted with poorer cognitive FIM (median 6 (IQR 5-14) compared to patients with aneurysms located elsewhere (median 12 (IQR 6-23) (p = 0.0129); no difference at discharge. No association between aneurysm location and functional independence was observed. Higher age was associated with poorer outcome in bowel management OR 0.54 (95% CI 0.31-0.92), bladder management OR 0.59 (95% CI 0.35-0.98), comprehension OR 0.53 (95% CI 0.30-0.94), and memory OR 0.48 (95% CI 0.25-0.93). Overall, FIM at admission was associated with functional independence at discharge with the exception of stair walking and bladder management which did not reach statistical significance. ACoA was not associated with poorer level of functional independence compared to patients with a-SAH located elsewhere. Higher age was associated with poorer outcome in continence, comprehension, and memory, whereas higher FIM was associated with better functional independence across items at discharge.

    Living close to high traffic has been linked to subclinical atherosclerosis, however it is not clear, whether fine particulate matter (PM) air pollution or noise, two important traffic-related exposures, are responsible for the association. We investigate the independent associations of long-term exposure to fine PM and road traffic noise with thoracic aortic calcification (TAC), a reliable measure of subclinical atherosclerosis. We used baseline data (2000-2003) from the German Heinz Nixdorf Recall Study, a population-based cohort of 4814 randomly selected participants. We assessed residential long-term exposure to PM with a chemistry transport model, and to road traffic noise using façade levels from noise models as weighted 24 h mean noise (Lden) and night-time noise (Lnight). Thoracic aortic calcification was quantified from non-contrast enhanced electron beam computed tomography. We used multiple linear regression to estimate associations of environmental exposures with ln(TAC+1), adjusting for each other, individual, and neighbourhood characteristics. In 4238 participants (mean age 60 years, 49.9% male), PM2.5 (aerodynamic diameter ≤2.5 µm) and Lnight are both associated with an increasing TAC-burden of 18.1% (95% CI: 6.6; 30.9%) per 2.4 µg/m(3) PM2.5 and 3.9% (95% CI 0.0; 8.0%) per 5dB(A) Lnight, respectively, in the full model and after mutual adjustment. We did not observe effect measure modification of the PM2.5 association by Lnight or vice versa. Long-term exposure to fine PM and night-time traffic noise are both independently associated with subclinical atherosclerosis and may both contribute to the association of traffic proximity with atherosclerosis.

    Quantum key distribution provides information-theoretically-secure communication. In practice, device imperfections may jeopardise the system security. Device-independent quantum key distribution solves this problem by providing secure keys even when the quantum devices are untrusted and uncharacterized. Following a recent security proof of the device-independent quantum key distribution, we improve the key rate by tightening the parameter choice in the security proof. In practice where the system is lossy, we further improve the key rate by taking into account the loss position information. From our numerical simulation, our method can outperform existing results. Meanwhile, we outline clear experimental requirements for implementing device-independent quantum key distribution. The maximal tolerable error rate is 1.6%, the minimal required transmittance is 97.3%, and the minimal required visibility is 96.8 % .

    We examined independent and joint associations of objectively measured physical activity (PA) and physical fitness (PF) with pain, fatigue and the overall impact of fibromyalgia in 386 fibromyalgia women aged 51.2 ± 7.6 years. Levels of PA (light, moderate and vigorous) and PF were measured with triaxial accelerometry and the Senior Fitness Test, respectively. We used the Short-Form health survey-36 pain sub-scale and the Multidimensional Fatigue Inventory to assess pain and multiple dimensions of fatigue, respectively. The impact of fibromyalgia was studied with the Revised Fibromyalgia Impact Questionnaire (FIQR). Both, total PA and global PF were independently associated with pain pressure threshold, SF-36 pain, reduced activity, reduced motivation and FIQR total score (all, P ≤ 0.027). The associations between total PA and symptoms were weaker than those observed between global PF and symptoms. Overall, unfit patients with low PA showed a worse profile that fit patients with high PA (all, P ≤ 0.001). In summary, PA and PF are independently associated with pain, fatigue and the overall impact of fibromyalgia in women. Although PF presented greater associations with symptoms, the results suggest that both being physically active and keep adequate fitness levels might be convenient for fibromyalgia women.

    to determine whether prolactin levels are independently associated with disease damage in systemic lupus erythematosus (SLE) patients. these cross-sectional analyses were conducted in SLE patient members of the Almenara Lupus Cohort who were seen between January 2012 and June 2013. Disease damage was ascertained with the System Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR) damage index (SDI). Prolactin was measured in ng/ml. The association between prolactin levels and the SDI (total and its domains) was evaluated using Spearman's correlation. Subsequently, adjusted Poisson regression models were performed to evaluate these associations. 160 patients were included. 147 (91.9%) were female; their median age at diagnosis was 33.4 (interquartile range (IQR): 26.0-44.3) years; their disease duration was 5.5 (IQR: 2.6-9.7) years. The median prolactin value was 16.8 (IQR: 11.8-24.5) ng/ml. After adjusting for confounders in the Poisson regression model the estimated rate ratios (RR) and 95% confidence interval (CI) for each 10 ng/ml increment of prolactin were 1.13 (95% CI 1.60-1.20, p<0.001) for the total SDI score, 1.15 (1.03-1.28, p=0.003) for the renal domain and 1.41 (1.11-1.79, p=0.003) for the cardiac/peripheral vascular domains. there was a positive association between prolactin levels and the SDI (overall and its renal and cardiac/peripheral vascular domains), independently of other well-known risk factors. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Medical home initiatives encourage primary care practices to invest in new structural capabilities such as patient registries and information technology, but little is known about the costs of these investments. To estimate costs of transformation incurred by primary care practices participating in a medical home pilot. We interviewed practice leaders in order to identify changes practices had undertaken due to medical home transformation. Based on the principles of activity-based costing, we estimated the costs of additional personnel and other investments associated with these changes. The Pennsylvania Chronic Care Initiative (PACCI), a statewide multi-payer medical home pilot. Twelve practices that participated in the PACCI. One-time and ongoing yearly costs attributed to medical home transformation. Practices incurred median one-time transformation-associated costs of $30,991 per practice (range, $7694 to $117,810), equivalent to $9814 per clinician ($1497 to $57,476) and $8 per patient ($1 to $30). Median ongoing yearly costs associated with transformation were $147,573 per practice (range, $83,829 to $346,603), equivalent to $64,768 per clinician ($18,585 to $93,856) and $30 per patient ($8 to $136). Care management activities accounted for over 60% of practices' transformation-associated costs. Per-clinician and per-patient transformation costs were greater for small and independent practices than for large and system-affiliated practices. Error in interviewee recall could affect estimates. Transformation costs in other medical home interventions may be different. The costs of medical home transformation vary widely, creating potential financial challenges for primary care practices-especially those that are small and independent. Tailored subsidies from payers may help practices make these investments. Agency for Healthcare Research and Quality.

  15. Practical method for targeted disruption of cilia-related genes by using CRISPR/Cas9-mediated, homology-independent knock-in system.

    The CRISPR/Cas9 system has revolutionized genome editing in virtually all organisms. Although the CRISPR/Cas9 system enables the targeted cleavage of genomic DNA, its use for gene knock-in remains challenging because levels of homologous recombination activity vary among various cells. In contrast, the efficiency of homology-independent DNA repair is relatively high in most cell types. Therefore the use of a homology-independent repair mechanism is a possible alternative for efficient genome editing. Here we constructed a donor knock-in vector optimized for the CRISPR/Cas9 system and developed a practical system that enables efficient disruption of target genes by exploiting homology-independent repair. Using this practical knock-in system, we successfully disrupted genes encoding proteins involved in ciliary protein trafficking, including IFT88 and IFT20, in hTERT-RPE1 cells, which have low homologous recombination activity. The most critical concern using the CRISPR/Cas9 system is off-target cleavage. To reduce the off-target cleavage frequency and increase the versatility of our knock-in system, we constructed a universal donor vector and an expression vector containing Cas9 with enhanced specificity and tandem sgRNA expression cassettes. We demonstrated that the second version of our system has improved usability. © 2017 Katoh et al.

    Davis, Ronald M; Müllner, Marcus

    2002-10-01

    The purpose of this study was to assess the degree of editorial independence at a sample of medical journals and the relationship between the journals and their owners. We surveyed the editors of 33 medical journals owned by not-for-profit organizations ("associations"), including 10 journals represented on the International Committee of Medical Journal Editors (nine of which are general medical journals) and a random sample of 23 specialist journals with high impact factors that are indexed by the Institute for Scientific Information. The main outcome measures were the authority to hire, fire, and oversee the work of the editor; the editor's tenure and financial compensation; control of the journal's budget; publication of material about the association; and the editor's perceptions about editorial independence and pressure over editorial content. Of the 33 editors, 23 (70%) reported having complete editorial freedom, and the remainder reported a high level of freedom (a score of > or = 8, where 10 equals complete editorial freedom and 1 equals no editorial freedom). Nevertheless, a substantial minority of editors reported having received at least some pressure in recent years over editorial content from the association's leadership (42%), senior staff (30%), or rank-and-file members (39%). The association's board of directors has the authority to hire (48%) or fire (55%) the editor for about half of the journals, and the editor reports to the board for 10 journals (30%). Twenty-three editors (70%) are appointed for a specific term (median term = 5 years). Three-fifths of the journals have no control over their profit, and the majority of journals use the association's legal counsel and/or media relations staff. Stronger safeguards are needed to give editors protection against pressure over editorial content, including written guarantees of editorial freedom and governance structures that support those guarantees. Strong safeguards are also needed because editors

    We aimed to evaluate the association between sleep quality and physical disability in community-dwelling older adults. There were 213 community-dwelling adults (76 men and 137 women) aged 65 years and above participated into this investigation. The Groningen Activity Restriction Scale and the Pittsburgh Sleep Quality Index were utilized to evaluate physical disability and subjective sleep quality, respectively. Global functional capacity was measured by the 6-minute walk test (6MWT). The Mini Mental State Examination and the Chinese Geriatric Depression Screening Scale were used to evaluate cognitive function and depression. Univariate analysis revealed a correlation between physical disability and poor sleep quality, older age, 2 or more comorbidities, depression, functional capacity, and poor cognitive function. However, in the multivariate analyses, depression failed to show significant association with physical disability. In contrast, an independent association was observed between poor sleep quality and physical disability (OR = 2.03; 95% CI: 1.02-4.05). In community-dwelling older adults, subjective poor sleep was significantly associated with physical disability, even after controlling for the effects of other established risk factors. © 2014 American Academy of Sleep Medicine.

    The objective of this study was to evaluate cross-sectional and longitudinal associations between ankle-brachial index (ABI) and indicators of cognitive function. Randomized clinical trial (Lifestyle Interventions and Independence for Elders Trial). Eight US academic centers. A total of 1601 adults ages 70-89 years, sedentary, without dementia, and with functional limitations. Baseline ABI and interviewer- and computer-administered cognitive function assessments were obtained. These assessments were used to compare a physical activity intervention with a health education control. Cognitive function was reassessed 24 months later (interviewer-administered) and 18 or 30 months later (computer-administered) and central adjudication was used to classify individuals as having mild cognitive impairment, probable dementia, or neither. Lower ABI had a modest independent association with poorer cognitive functioning at baseline (partial r = 0.09; P < .001). Although lower baseline ABI was not associated with overall changes in cognitive function test scores, it was associated with higher odds for 2-year progression to a composite of either mild cognitive impairment or probable dementia (odds ratio 2.60 per unit lower ABI; 95% confidence interval 1.06-6.37). Across 2 years, changes in ABI were not associated with changes in cognitive function. In an older cohort sedentary individuals with dementia and with functional limitations, lower baseline ABI was independently correlated with cognitive function and associated with greater 2-year risk for progression to mild cognitive impairment or probable dementia.

    2000-12-01

    In this article, findings from a qualitative study of a cohort of occupational therapy students in Auckland, New Zealand are presented. The study focussed on the experiences of students as they learned to work with people from different social and cultural backgrounds over a 3-year period. As well as identifying curriculum and teaching/learning processes that enhance intercultural competence development, the data that emerged from the study also highlight important issues about how occupation and independence are conceptualised across cultures. A review of the trans-disciplinary and occupational therapy literature dealing with theoretical, conceptual and educational issues relating to cross-cultural practice is followed by a presentation of narrative extracts that address the key concepts of occupation and independence. These are then discussed with reference to relevant occupational therapy literature. In conclusion, implications for future research and practice are explored focussing on a need for occupation and independence to be reconsidered as culturally relative constructions.

  20. Accounting for independent nondifferential misclassification does not increase certainty that an observed association is in the correct direction.

    Researchers sometimes argue that their exposure-measurement errors are independent of other errors and are nondifferential with respect to disease, resulting in estimation bias toward the null. Among well-known problems with such arguments are that independence and nondifferentiality are harder to satisfy than ordinarily appreciated (e.g., because of correlation of errors in questionnaire items, and because of uncontrolled covariate effects on error rates); small violations of independence or nondifferentiality may lead to bias away from the null; and, if exposure is polytomous, the bias produced by independent nondifferential error is not always toward the null. The authors add to this list by showing that, in a 2 x 2 table (for which independent nondifferential error produces bias toward the null), accounting for independent nondifferential error does not reduce the p value even though it increases the point estimate. Thus, such accounting should not increase certainty that an association is present.

    Prescribing is a complex and error-prone task that demands expertise. McLellan et al.'s theory of expertise development model ("the model"), developed to assess medical literature on prescribing by medical students, proposes that in order to develop, individuals should deliberately engage their knowledge, skills and attitudes within a social context. Its applicability to independent prescribers (IP) is unknown. A systematic review was conducted to explore whether the model is applicable to non-medical independent prescribing and to assess the factors underpinning expertise development reported in the literature. Six electronic databases (EMBASE, Medline, AMED, CINAHL, IPA and PsychInfo) were searched for articles published between 2006 and 2016, reporting empirical data on pharmacist and nurse IPs education or practice. Data were extracted using themes from the model and analysed using framework analysis. Thirty-four studies met the inclusion criteria. Knowledge, pre-registration education, experience, support and confidence were some of the intrinsic and extrinsic factors influencing IPs. Difficulty in transferring theory to practice was attributed to lack of basic pharmacology and bioscience content in pre-registration nursing rather than the prescribing programme. Students saw interventions using virtual learning or learning in practice as more useful with long-term benefits e.g. students were able to use their skills in history taking following the virtual learning intervention 6-months after the programme. All studies demonstrated how engaging knowledge and skills affected individuals' attitude by, for example, increasing professional dignity. IPs were able to develop their expertise when integrating their competencies in a workplace context with support from colleagues and adherence to guidelines. This is the first study to synthesize data systematically on expertise development from studies on IPs using the model. The model showed the need for stronger

    Pressure ulcers are the common conditions among patients hospitalized in acute and chronic care facilities and impose significant burden on patients, their relatives and caregivers. Pressure ulcers have been described as one of the most costly and physically debilitating complications since the 20(th) century. The pain and discomfort due to pressure ulcer prolongs illness, rehabilitation, time of discharge and even contribute to disability and death. This study was aimed to assess knowledge, practice and factors associated with pressure ulcer prevention among nurses in Gondar University Hospital, North-west Ethiopia. An institution-based cross-sectional survey was conducted from March 15 - April 10, 2014 among 248 nurses in Gondar University hospital. A pretested and structured self-administered questionnaire was used for data collection. Data were entered using EPI info version 3.5.3 statistical software and analyzed using SPSS version 20 statistical package. Descriptive statistics was used to describe the study population in relation to relevant variables. Bivariate and multivariate logistic regression was also carried out to see the effect of each independent variable on the dependent variable. Nearly half (54.4 %) of the nurses had good knowledge; similarly 48.4 % of them had good practice on prevention of pressure ulcer. Educational status [Adjusted Odds Ratio (AOR) = 2.4, 95 % CI (1.39-4.15)], work experience [AOR = 4.8, 95 % CI (1.31-10.62)] and having formal training [AOR = 4.1, 95 % CI (1.29-9.92)] were significantly associated with knowledge on prevention of pressure ulcer. While, satisfaction with nursing leadership [AOR = 1.9, 95 % CI (1.04-3.82)], staff shortage [AOR = 0.07, 95 % CI (0.03-0.13)] and inadequate facilities and equipment [AOR = 0.4, 95 % CI (0.19-0.83)] were found to be significantly associated with the practice on prevention of pressure ulcer.

    The effect of a rapidly changing healthcare system on personnel turnover in community family practices has not been analyzed. We describe physician and staff turnover and examine its association with practice characteristics and patient outcomes. A cross-sectional evaluation of length of employment of 150 physicians and 762 staff in 77 community family practices in northeast Ohio was conducted. Research nurses collected data using practice genograms, key informant interviews, staff lists, practice environment checklists, medical record reviews, and patient questionnaires. The association of physician and staff turnover with practice characteristics, patient satisfaction, and preventive service data was tested. During a 2-year period, practices averaged a 53% turnover rate of staff. The mean length of duration of work at the current practice location was 9.1 years for physicians and 4.1 years for staff. Longevity varied by position, with a mean of 3.4 years for business employees, 4.0 years for clinical employees, and 7.8 years for office managers. Network-affiliated practices experienced higher turnover than did independent practices. Physician longevity was associated with a practice focus on managing chronic illness, keeping on schedule, and responding to insurers' requests. No association was found between turnover and patient satisfaction or preventive service delivery rates. Personnel turnover is pervasive in community primary care practices and is associated with employee role, practice network affiliation, and practice focus. The potentially disruptive effect of personnel turnover on practice functioning, finances, and longitudinal relationships with patients deserves further study despite the reassuring lack of association with patient satisfaction and preventive service delivery rates.

    This cross-sectional study examined the association between controlling feeding practices and children's appetite traits. The secondary aim studied the relationship between controlling feeding practices and two proxy indicators of diet quality. Participants were 203 Australian-Indian mothers with children aged 1-5 years. Controlling feeding practices (pressure to eat, restriction, monitoring) and children's appetite traits (food approach traits: food responsiveness, enjoyment of food, desire to drink, emotional overeating; food avoidance traits: satiety responsiveness, slowness in eating, fussiness and emotional undereating) were measured using self-reported, previously validated scales/questionnaires. Children's daily frequency of consumption of core and non-core foods was estimated using a 49-item list of foods eaten (yes/no) in the previous 24 hours as an indicator of diet quality. Higher pressure to eat was associated with higher scores for satiety responsiveness, slowness in eating, fussiness and lower score for enjoyment of food. Higher restriction was related to higher scores for food responsiveness and emotional overeating. Higher monitoring was inversely associated with fussiness, slowness in eating, food responsiveness and emotional overeating and positively associated with enjoyment of food. Pressure to eat and monitoring were related to lower number of core and non-core foods consumed in the previous 24 hours, respectively. All associations remained significant after adjusting for maternal and child covariates (n = 152 due to missing data). In conclusion, pressure to eat was associated with higher food avoidance traits and lower consumption of core foods. Restrictive feeding practices were associated with higher food approach traits. In contrast, monitoring practices were related to lower food avoidance and food approach traits and lower non-core food consumption. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Social communication skills are critical in the health professions. The aim of this study was to measure and identify professional practice predictors of social communication skills of practicing chiropractors. The study population was derived from a group of doctors of chiropractic who participated in a practice-based research program. Participating chiropractors agreed to complete a survey detailing the chiropractor's sex, years in practice, practice type, size of the practice community, typical weekly practice volume, and an instrument to measure skills of social communication. Regression analysis was applied to identify associations between independent variables and responses to the social skills instrument. Results suggested that selected characteristics of clinical practice may be associated with clinician's social skills of communication. The weekly volume of patients to the practice emerged as a salient explanatory factor of overall social communication skills and as a factor individually for dimensions of social expressivity and social control. The practice arrangement (solo vs group) proved important in terms of respondent emotional control scores. Similarly, the solo vs group practice variable was associated with higher levels of emotional sensitivity; however, this association was mediated by the sex of the doctor of chiropractic; men reported lower levels of emotional sensitivity than women. The findings of this study suggest associations between dimensions of social communication skills, practice characteristics, practice arrangements, and sex that may inform the efforts of educators as they endeavor to better prepare health professionals for practice in a wide spectrum of settings.

    The effect of pregnancy intention on post-natal practices like breastfeeding is still poorly understood in the Philippines. In this light, this study aims to determine the association between pregnancy intention and optimal breastfeeding practices in the Philippines. This is a cross-sectional study design using the 2003 Philippine National Demographic and Health Survey. Logistic regression analysis was used to determine the independent association of pregnancy intention and optimal breastfeeding practices. The study includes 3,044 last-born children aged 6-36 months at the time of survey. Dead children were also included as long as their age of death satisfies the age criterion. Children born from mistimed pregnancies are more likely to have late breastfeeding initiation compared to children born from wanted pregnancies (OR = 1.44; 90%CI: 1.17-1.78). However, this occurs only among children belonging to households with low socio-economic status. Among children belonging to households with high socio-economic status, no significant effect of pregnancy intention on breastfeeding initiation was observed. Children born from unwanted pregnancies are less likely to have short breastfeeding duration (OR = 0.60; 90%CI: 0.48-0.76). However, this occurs only among children belonging to households with high socioeconomic status. No significant effect of pregnancy intention on breastfeeding duration was observed among children belonging to households with low socio-economic status. The findings of this study suggest that there are different effects of pregnancy intention on the two types of optimal breastfeeding practices examined. With regards to breastfeeding duration, it was found that among infants belonging to high SES, the odds of having short breastfeeding duration is lower among children born from unwanted pregnancies compared to children born from wanted one. Conversely, children belonging to low SES household, the odds of having late breastfeeding

    2013-05-01

    A new extension to the way in which the Bidirectional Associative Memory (BAM) algorithms are implemented is presented here. We will show that by utilizing the singular value decomposition (SVD) and integrating principles of independent component analysis (ICA) into the nullspace (NS) we have created a novel approach to mitigating spurious attractors. We demonstrate this with two applications. The first application utilizes a one-layer association while the second application is modeled after the several hierarchal associations of ventral pathways. The first application will detail the way in which we manage the associations in terms of matrices. The second application will take what we have learned from the first example and apply it to a cascade of a convolutional neural network (CNN) and perceptron this being our signal processing model of the ventral pathways, i.e., visual systems.

    There are no tools or biomarkers for a quantitative analysis of sarcopenia. Cross-sectional study of the diagnosis of sarcopenia in 200 independent adults aged 70 years or over. Sarcopenia was defined as loss of muscle mass together with low strength and/or loss of physical performance. We considered different clinical parameters and assayed potential blood biomarkers (cell energetic metabolism, muscle performance, inflammation, infection and oxidative stress). The prevalence of sarcopenia was 35.3% in women and 13.1% in men, and it was significantly associated with advanced age, a low functional performance in the lower extremities, deficient weekly consumption of kilocalories, risk of malnutrition, and drug use for the digestive system. A close relationship was found between sarcopenia, pre-frailty and depressed mood. With these confounding variables, we observed that products of lipid peroxidation were closely associated with sarcopenia in independent older adults (frail participants and those with severe dependence had been excluded from the sample). The best multivariate model proposed was able to predict 67.6% of the variance in sarcopenia, with a power of discrimination of 93.5%. Additional analyses considering lipid levels, fat mass, dyslipidemia, use of lipid-lowering drugs and hypertension confirmed this close association between lipid peroxidation and sarcopenia. Given the difficulty in the diagnosis of sarcopenia in clinical practice, we suggest the use of blood circulating products of lipid peroxidation as potential biomarkers for an early diagnosis of sarcopenia in independent older adults.

    Health benefits from children's independent mobility and active travel beyond school travel are largely unexplored. This review synthesized the evidence for associations of independent mobility and active travel to various destinations with physical activity, sedentary behaviour and weight status. Systematic review. A systematic search in six databases (PubMed, Scopus, CINAHL, SportDiscus, PsychInfo, TRIS) for papers published between January 1990 and March 2012 was undertaken, focussing on children aged 3-18 years. Study inclusion and methodological quality were independently assessed by two reviewers. 52 studies were included. Most studies focussed solely on active travel to and/or from school, and showed significant positive associations with physical activity. The same relationship was detected for active travel to leisure-related places and independent mobility with physical activity. An inverse relationship between active travel to school and weight status was evident but findings were inconsistent. Few studies examined correlations between active travel to school and self-reported screen-time or objectively measured sedentary behaviour, and findings were unclear. Studies on independent mobility suggested that children who have the freedom to play outdoors and travel actively without adult supervision accumulate more physical activity than those who do not. Further investigation of children's active travel to leisure-related destinations, measurement of diverse sedentary behaviour beyond simply screen-based activities, and consistent thresholds for objectively measured sedentary behaviour in children will clarify the inconsistent evidence base on associations of active travel with sedentary behaviour and weight status.

  12. Central Body Fat Distribution Associates with Unfavorable Renal Hemodynamics Independent of Body Mass Index

    2013-01-01

    Central distribution of body fat is associated with a higher risk of renal disease, but whether it is the distribution pattern or the overall excess weight that underlies this association is not well understood. Here, we studied the association between waist-to-hip ratio (WHR), which reflects central adiposity, and renal hemodynamics in 315 healthy persons with a mean body mass index (BMI) of 24.9 kg/m2 and a mean 125I-iothalamate GFR of 109 ml/min per 1.73 m2. In multivariate analyses, WHR was associated with lower GFR, lower effective renal plasma flow, and higher filtration fraction, even after adjustment for sex, age, mean arterial pressure, and BMI. Multivariate models produced similar results regardless of whether the hemodynamic measures were indexed to body surface area. Thus, these results suggest that central body fat distribution, independent of BMI, is associated with an unfavorable pattern of renal hemodynamic measures that could underlie the increased renal risk reported in observational studies.

    Skin tears cause pain, increased length of stay, increased costs, and reduced quality of life. Minimal research reports the association between skin tears, and malnutrition using robust measures of nutritional status. This study aimed to articulate the association between malnutrition and skin tears in hospital inpatients using a yearly point prevalence of inpatients included in the Queensland Patient Safety Bedside Audit, malnutrition audits and skin tear audits conducted at a metropolitan tertiary hospital between 2010 and 2015. Patients were excluded if admitted to mental health wards or were <18 years. A total of 2197 inpatients were included, with a median age of 71 years. The overall prevalence of skin tears was 8.1%. Malnutrition prevalence was 33.5%. Univariate analysis demonstrated associations between age (P ˂ .001), body mass index (BMI) (P < .001) and malnutrition (P ˂ .001) but not gender (P = .319). Binomial logistic regression analysis modelling demonstrated that malnutrition diagnosed using the Subjective Global Assessment was independently associated with skin tear incidence (odds ratio, OR: 1.63; 95% confidence interval, CI: 1.13-2.36) and multiple skin tears (OR 2.48 [95% CI 1.37-4.50]). BMI was not independently associated with skin tears or multiple skin tears. This study demonstrated independent associations between malnutrition and skin tear prevalence and multiple skin tears. It also demonstrated the limitations of BMI as a nutritional assessment measure. © 2018 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

    Erectile dysfunction (ED) is common among men with an elevated body mass index (BMI). However, a high waist circumference (WC) and low levels of physical activity may predict ED independently of BMI. We investigated the independent relationships between BMI, WC, and physical activity with ED. Subjects consisted of 3,941 adult men (age > or = 20 years) with no history of prostate cancer from the 2001-2004 National Health and Nutrition Examination Survey. Logistic regression analyses were used to examine the relative odds of ED association with categories of BMI, WC, and physical activity. Established thresholds were used to divide subjects into three WC and BMI categories. Physical activity level was divided into active (> or =150 min/week), moderately active (30-149 min/week), and inactive (<30 min/week) categories. A single survey question was used to assess the presence of ED. After control for potential confounders, men with either a high WC or an obese BMI had an approximately 50% higher odds of having ED compared with men with a low WC or a normal BMI, respectively. Further, moderately active or inactive men had an approximately 40-60% greater odds of ED compared with active men. When all three predictors (WC, BMI, and physical activity level) were entered into the same logistic regression model, both a high WC and low physical activity level (moderately active and inactive) were independently associated with a greater odds of ED, whereas BMI level was not. Maintaining a WC level below 102 cm and achieving the recommended amount of moderate-intensity physical activity (>or =150 min/week) is associated with the maintenance of proper erectile function, regardless of BMI level. These findings suggest that the clinical screening for ED risk should include the assessment of WC and physical activity level in addition to BMI.

    Older adults are at increased risk for adverse events after surgical procedures. Loss of independence (LOI), defined as a decline in function or mobility, increased care needs at home, or discharge to a nonhome destination, is an important patient-centered outcome measure. To evaluate LOI among older adult patients after surgical procedures and examine the association of LOI with readmission and death after discharge in this population. This retrospective cohort study examined 9972 patients 65 years and older with known baseline function, mobility, and living situation undergoing inpatient operations from January 2014 to December 2014 at 26 hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program Geriatric Surgery Pilot Project. A total of 4895 patients were excluded because they were totally dependent, classified as class 5 by the American Society of Anesthesiologists, undergoing orthopedic or spinal procedures, or died prior to discharge. Loss of independence at time of discharge. Readmission and death after discharge. Of the 5077 patients included in this study, 2736 (53.9%) were female and 3876 (76.3%) were white, with a mean (SD) age of 75 (7) years. For this cohort, LOI increased with age; LOI occurred in 1386 of 2780 patients (49.9%) aged 65 to 74 years, 1162 of 1726 (67.3%) aged 75 to 84 years, and 479 of 571 (83.9%) 85 years and older (P < .001). Readmission occurred in 517 patients (10.2%). In a risk-adjusted model, LOI was strongly associated with readmission (odds ratio, 1.7; 95% CI, 1.4-2.2) and postoperative complication (odds ratio, 6.7; 95% CI, 4.9-9.0). Death after discharge occurred in 69 patients (1.4%). After risk adjustment, LOI was the strongest factor associated with death after discharge (odds ratio, 6.7; 95% CI, 2.4-19.3). Postoperative complication was not significantly associated with death after discharge. Loss of independence, a patient-centered outcome, was associated with

    Safety climate, a group-level measure of workers' perceptions regarding management's safety priorities, has been suggested as a key predictor of safety outcomes. However, its relationship with actual injury rates is inconsistent. We posit that safety climate may instead be a parallel outcome of workplace safety practices, rather than a determinant of workers' safety behaviors or outcomes. Using a sample of 25 commercial construction companies in Colombia, selected by injury rate stratum (high, medium, low), we examined the relationship between workers' safety climate perceptions and safety management practices (SMPs) reported by safety officers. Workers' perceptions of safety climate were independent of their own company's implementation of SMPs, as measured here, and its injury rates. However, injury rates were negatively related to the implementation of SMPs. Safety management practices may be more important than workers' perceptions of safety climate as direct predictors of injury rates. © 2017 Wiley Periodicals, Inc.

    Although studies have shown that chronic obstructive pulmonary disease (COPD) and hypertension are linked as comorbidities, it remains unclear whether COPD is independently associated with the risk of hypertension or is caused by common risk factors such as age and smoking. The objective of this study was to investigate the relationship between COPD and hypertension by using nationally representative data.This cross-sectional study analyzed data from the Korea National Health and Nutrition Examination Survey V conducted during 2010 to 2012. Hypertension was defined as a mean systolic blood pressure ≥ 140 mm Hg and/or a diastolic blood pressure ≥ 90 mm Hg, or current consumption of antihypertensive medications. A diagnosis of COPD was defined as a smoking history of at least 10 pack-years with airflow limitation on spirometry. Multivariate logistic regression was performed to investigate the independent association between COPD and hypertension after adjusting for covariates. Survey design analyses were conducted for all analyses.Among 4043 men (aged ≥ 40 years) who underwent spirometry, 2190 (54.2%) had hypertension. Even after adjusting for age, body mass index, smoking status, diabetes, metabolic syndrome, and stroke, COPD was independently associated with hypertension (adjusted odds ratio, 1.71; 95% confidence interval, 1.37-2.13; P < .001). Adjusted pulse pressure significantly increased as the ratio of forced expiratory volume in 1 s (FEV1) to forced vital capacity and FEV1 decreased.COPD is independently associated with hypertension, and this could explain the link between the risk of cardiovascular diseases and COPD.

    In a few studies, cirrhosis has been associated with increased mortality in patients with acute respiratory distress syndrome (ARDS). These studies were, however, conducted mostly before 2000. Over the last 15 years, the prognosis of cirrhotic patients admitted to the intensive care unit (ICU) seems to have improved and major changes in the management of mechanical ventilation (MV) of ARDS have appeared. The aim of this study was to determine whether cirrhosis remains a factor for poor prognosis despite improvements in MV techniques and supportive therapies for ARDS. Retrospective analysis of data recorded from 232 patients (42 with cirrhosis and 290 without cirrhosis) who received lung-protective ventilation for ARDS defined according to American-European Consensus Conference criteria and admitted from 2006 to 2013. Alcohol was the most common aetiology of the cirrhosis. The end point was mortality at day-90 from the diagnosis of ARDS, survival was calculated using the Kaplan-Meier method, and we used a Cox-proportional hazard model to determine whether cirrhosis remained independently associated with mortality after adjustment for other prognostic variables for ARDS described previously. Organ dysfunctions were assessed based on the Sequential Organ Failure Assessment (SOFA) criteria, pulmonary and nonpulmonary dysfunctions were distinguished and compared between cirrhotic and non-cirrhotic patients on the first 3 days of VM. Comparison of survival curves showed that cirrhotic patients had a poorer 90-day prognosis than non-cirrhotic patients (P = 0.03 by the log-rank test). After adjusted analysis, cirrhosis remained independently associated with mortality at day 90 (adjusted hazard ratio 2.09, 95% CI, 1.27-3.45, P = 0.004). Non-pulmonary SOFA scores were significantly higher in cirrhotic patients than in non-cirrhotic patients on day 1 (P < 0.001), day 2 (P = 0.003), and day 3 (P = 0.002) of MV for ARDS whereas pulmonary SOFA scores did not

    This report describes the challenges for advanced practice nurses (APNs) relative to supply and demand issues. The article also includes opportunities with the Balanced Budget Act, physician acceptance of Advanced Practice Nurses, and expanding practice opportunities. The challenges include the nursing shortage (both in nursing students and faculty), the aging of the nursing workforce, and a lag in nursing salaries; increased demand for nursing based on aging baby boomers, increasing patient acuity and technology, and new arenas for practice. The Balanced Budget Act of 1997 provided new opportunities for advanced practice nurses, including enhanced autonomy to provide services and bill independently of physicians. With these changes come new opportunities for advanced practice nurse entrepreneurs in the areas of independent practice, including opportunities to positively impact the health of families and communities in alignment with the Federal government's vision for "Healthy People 2010." As physician acceptance of advanced practice nurses continues to grow and in light of the changes in medical practice and education (residency reduction), opportunities to expand collaborative practice arrangements also exist. APNs are best suited to make the most of these changes. One example of an opportunity for independent practice, a Community Wellness Center, is developed as an entrepreneurial venture benefiting both the APN and the health of a community. Who better than registered nurses (RNs), especially those practicing at the advanced level, can ensure that these opportunities and challenges are addressed in an ethical manner and focused on the needs and health of the community?

    One of the aims of the Study of Infectious Intestinal Disease (IID) in England is to estimate the incidence of IID presenting to general practice. This sub-study aims to estimate and correct the degree of under-ascertainment in the national study. Cases of presumed IID which presented to general practice in the national study had been ascertained by their GP. In 26 general practices, cases with computerized diagnoses suggestive of IID were identified retrospectively. Cases which fulfilled the case definition of IID and should have been ascertained to the coordinating centre but were not, represented the under-ascertainment. Logistic regression modelling was used to identify independent factors which influenced under-ascertainment. The records of 2021 patients were examined, 1514 were eligible and should have been ascertained but only 974 (64%) were. There was variation in ascertainment between the practices (30% to 93%). Patient-related factors independently associated with ascertainment were: i) vomiting only as opposed to diarrhoea with and without vomiting (OR 0.37) and ii) consultation in the surgery as opposed to at home (OR 2.18). Practice-related factors independently associated with ascertainment were: i) participation in the enumeration study component (OR 1.78), ii) a larger number of partners (OR 0.3 for 7-8 partners); iii) rural location (OR 2.27) and iv) previous research experience (OR 1.92). Predicted ascertainment percentages were calculated according to practice characteristics. Under-ascertainment of IID was substantial (36%) and non-random and had to be corrected. Practice characteristics influencing variation in ascertainment were identified and a multivariate model developed to identify adjustment factors which could be applied to individual practices. Researchers need to be aware of factors which influence ascertainment in acute epidemiological studies based in general practice.

  1. Catheter-Associated Urinary Tract Infection by Pseudomonas aeruginosa Is Mediated by Exopolysaccharide-Independent Biofilms

    Pseudomonas aeruginosa is an opportunistic human pathogen that is especially adept at forming surface-associated biofilms. P. aeruginosa causes catheter-associated urinary tract infections (CAUTIs) through biofilm formation on the surface of indwelling catheters. P. aeruginosa encodes three extracellular polysaccharides, PEL, PSL, and alginate, and utilizes the PEL and PSL polysaccharides to form biofilms in vitro; however, the requirement of these polysaccharides during in vivo infections is not well understood. Here we show in a murine model of CAUTI that PAO1, a strain harboring pel, psl, and alg genes, and PA14, a strain harboring pel and alg genes, form biofilms on the implanted catheters. To determine the requirement of exopolysaccharide during in vivo biofilm infections, we tested isogenic mutants lacking the pel, psl, and alg operons and showed that PA14 mutants lacking these operons can successfully form biofilms on catheters in the CAUTI model. To determine the host factor(s) that induces the ΔpelD mutant to form biofilm, we tested mouse, human, and artificial urine and show that urine can induce biofilm formation by the PA14 ΔpelD mutant. By testing the major constituents of urine, we show that urea can induce a pel-, psl-, and alg-independent biofilm. These pel-, psl-, and alg-independent biofilms are mediated by the release of extracellular DNA. Treatment of biofilms formed in urea with DNase I reduced the biofilm, indicating that extracellular DNA supports biofilm formation. Our results indicate that the opportunistic pathogen P. aeruginosa utilizes a distinct program to form biofilms that are independent of exopolysaccharides during CAUTI. PMID:24595142

    Burnout has been suggested to be related to depression. We examined the relationship between burnout and allostatic load, and whether this association is independent of psychological distress and depression. We measured burnout psychological distress, depression, and allostatic load in 3283 participants. Higher burnout (β = 0.06, p =0.003) and cynicism (β = 0.03, p = 0.031) and decreased professional efficacy (β = 0.03, p = 0.007) were related to higher allostatic load independent of age, sex, education, occupation and psychological distress. Depression, however, explained 60 percent of the association. Burnout is related to higher allostatic load, and this association partly overlaps with co-occurring depression. © The Author(s) 2014.

    2011-01-01

    This research compares two types of consumer organizations in one state in order to explore the significance of organizational independence for internal structure/operations and external relationships. The first type, consumeroperated service organizations (COSOs), are independent and fully self-governing; the second are peer-support service organizations (PSSOs), which are part of larger non-consumer entities. Mail surveys were completed by COSO and PSSO directors of a geographically representative sample of organizations; telephone interviews were conducted with a sub-sample. Owing to small sample size, matched COSO-PSSO pairs were analyzed using non-parametric statistics. COSOs and PSSOs are similar in some ways, e.g., types of services provided, but significantly different on internal variables, such as budget size, and external variables, such as number of relationships with community groups. Organizational independence appears to be a significant characteristic for consumer service organizations and should be encouraged by funders and among participants. Funders might establish administrative and/or programmatic measures to support consumer organizations that are independent or moving toward independence; their participants would also benefit from the provision, by authorities or advocates, of materials to guide organizations toward, for example, 501(c)3 status.

    Enlarged perivascular spaces (EPVS) have been identified as a marker of cerebral small vessel diseases (CSVD). Ambulatory blood pressure (ABP) is the strongest predictor of hypertension-related brain damage. However, the relationship between ABP levels and EPVS is unclear. This study aimed to investigate the association between ABP levels and EPVS by 24-hour ambulatory blood pressure monitoring (ABPM). We prospectively recruited inpatients for physical examinations in our hospital from May 2013 to Jun 2016. 24-hour ABPM data and cranial magnetic resonance imaging information were collected. EPVS in basal ganglia (BG) and centrum semiovale (CSO) were identified and classified into three categories by the severity. White matter hyperintensities were scored by Fazekas scale. Spearman correlation analysis and multiple logistic regression analysis were used to determine the relationship between ABP levels and EPVS. A total of 573 subjects were enrolled in this study. 24-hour, day and night systolic blood pressure (SBP) levels were positively related to higher numbers of EPVS in BG (24-hour SBP: r = 0.23, p < 0.01; day SBP: r = 0.25, p < 0.01; night SBP: r = 0.30, p < 0.01). The association was unchanged after controlling for confounders by multiple logistic regression analysis. 24-hour and day diastolic blood pressure (DBP) levels increased with an increasing degree of EPVS in CSO (p = 0.04 and 0.049, respectively). But the association disappeared after adjusting for confounders. Spearman correlation analysis indicated that ABP levels were not associated with higher numbers of EPVS in CSO (p > 0.05). DBP levels were not independently associated with the severity of EPVS in BG and CSO. Higher SBP levels were independently associated with EPVS in BG, but not in CSO, which supported EPVS in BG to be a marker of CSVD. Pathogenesis of EPVS in BG and CSO might be different.

    Background Somatoform disorders are an important factor in functional disability and role impairment, though their independent contribution to disability has been unclear because of prevalent medical and psychiatric comorbidity. Objectives To assess the extent of the overlap of somatization with other psychiatric disorders and medical problems, to compare the functional disability and role impairment of somatizing and non-somatizing patients, and to determine the independent contribution of somatization to functional disability and role impairment. Design Patients were surveyed with self-report questionnaires assessing somatization, psychiatric disorder, and role impairment. Medical morbidity was indexed with a computerized medical record audit. Participants Consecutive adults making scheduled visits to their primary care physicians at two hospital-affiliated primary care practices on randomly chosen days. Measurements Intermediate activities of daily living, social activities, and occupational disability. Results Patients with somatization, as well as those with serious medical and psychiatric illnesses, had significantly more impairment of activities of daily life and social activities. When these predictors were considered simultaneously in a multivariable regression, the association with somatization remained highly significant and was comparable to or greater than many major medical conditions. Conclusions Patients with somatization had substantially greater functional disability and role impairment than non-somatizing patients. The degree of disability was equal to or greater than that associated with many major, chronic medical disorders. Adjusting the results for psychiatric and medical co-morbidity had little effect on these findings. PMID:19031038

    This population-based study was aimed to determine whether there is an association between urinary tract infections (UTI) during pregnancy, among patients in whom antibiotic treatment was recommended, and maternal and perinatal outcome. A retrospective population-based study comparing all singleton pregnancies of patients with and without UTI was performed. Multiple logistic regression models were performed to control for confounders. Out of 199,093 deliveries, 2.3% (n = 4742) had UTI during pregnancy and delivery. Patients with UTI had significantly higher rates of intra-uterine growth restriction (IUGR), pre-eclampsia, caesarean deliveries (CD) and pre-term deliveries (either before 34 weeks or 37 weeks of gestation). Although controlling for possible confounders such as maternal age and parity, using multivariable analyses, the significant association between UTI and IUGR, pre-eclampsia, CD and preterm deliveries persisted. In contrast, no significant differences in 5-min Apgar scores less than 7 or perinatal mortality were noted between the groups (0.6% vs. 0.6%; p = 0.782, and 1.5% vs. 1.4%; p = 0.704, respectively). Maternal UTI is independently associated with pre-term delivery, pre-eclampsia, IUGR and CD. Nevertheless, it is not associated with increased rates of perinatal mortality compared with women without UTI.

  8. Rumination is independently associated with poor psychological health: Comparing emotion regulation strategies.

    PubMed

    2015-01-01

    Emotion regulation (ER) strategies are related to psychological health, with most work examining reappraisal and suppression. Yet, emerging findings suggest that rumination may have stronger relationships with psychological health, namely depression, than other ER strategies. This paper replicated and extended this work by testing whether rumination was independently associated with a range of poor psychological health risk indicators and outcomes. In addition, it explored whether the reason why rumination is so deleterious to health is because it underlies the stress-health relationship. Participants (n = 218) completed measures online. Surveys assessed ER strategies (reappraisal, suppression, proactive coping, emotion support seeking, and rumination), health risk indicators (hostility, optimism, self-esteem), health outcomes (depression, poor sleep quality, anxiety) and perceived chronic stress. Multivariate regression analyses revealed rumination as the only ER strategy with a consistent independent effect on all the health risk indicators and outcomes. Bootstrapping analyses revealed indirect effects of perceived chronic stress on all the health variables via rumination. Rumination had a deleterious relationship with psychological health, perhaps because rumination underlies the relationship between stress and psychological health. Results have implications for interventions, particularly emphasizing the need to target ruminative thinking after stressful experiences.

    General surgery residency training has changed with adoption of the 80-hour work week, patient expectations, and the malpractice environment, resulting in decreased resident autonomy during the chief resident year. There is considerable concern that graduating residents are not prepared for independent surgical practice. Two online surveys were developed, one for "young surgeons" (American College of Surgeons [ACS] Fellows 45 years of age and younger) and one for "older surgeons" (ACS Fellows older than 45 years of age). The surveys were distributed by email to 2,939 young and 9,800 older surgeons. The last question was open-ended with a request to provide comments. A qualitative and quantitative analysis of all comments was performed. The response rate was 9.6% (282 of 2,939) of young and 10% (978 of 9,800) of older surgeons. The majority of young surgeons (94% [58.7% strongly agree, 34.9% agree]) stated they had adequate surgical training and were prepared for transition to the surgery attending role (91% [49.6% strongly agree, 41.1% agree]). In contrast, considerably fewer older surgeons believed that there was adequate surgical training (59% [18.7% strongly agree, 40.2% agree]) or adequate preparation for transition to the surgery attending role (53% [16.93% strongly agree, 36.13% agree]). The 2 groups' responses were significantly different, chi-square test of association (3) = 15.73, p = 0.0012. Older surgeons focused considerably more on residency issues (60% vs 42%, respectively), and young surgeons focused considerably more on business and practice issues (30% vs 14%, respectively). Young and older surgeons' perceptions of general surgery residents' readiness to practice independently after completion of general surgery residency differ significantly. Future work should focus on determination of specific efforts to improve the transition to independent surgery practice for the general surgery resident.

    The authors sought to demonstrate that schizophrenia is a heterogeneous group of heritable disorders caused by different genotypic networks that cause distinct clinical syndromes. In a large genome-wide association study of cases with schizophrenia and controls, the authors first identified sets of interacting single-nucleotide polymorphisms (SNPs) that cluster within particular individuals (SNP sets) regardless of clinical status. Second, they examined the risk of schizophrenia for each SNP set and tested replicability in two independent samples. Third, they identified genotypic networks composed of SNP sets sharing SNPs or subjects. Fourth, they identified sets of distinct clinical features that cluster in particular cases (phenotypic sets or clinical syndromes) without regard for their genetic background. Fifth, they tested whether SNP sets were associated with distinct phenotypic sets in a replicable manner across the three studies. The authors identified 42 SNP sets associated with a 70% or greater risk of schizophrenia, and confirmed 34 (81%) or more with similar high risk of schizophrenia in two independent samples. Seventeen networks of SNP sets did not share any SNP or subject. These disjoint genotypic networks were associated with distinct gene products and clinical syndromes (i.e., the schizophrenias) varying in symptoms and severity. Associations between genotypic networks and clinical syndromes were complex, showing multifinality and equifinality. The interactive networks explained the risk of schizophrenia more than the average effects of all SNPs (24%). Schizophrenia is a group of heritable disorders caused by a moderate number of separate genotypic networks associated with several distinct clinical syndromes.

    One important public health issue associated with opioid use today is the risk of hepatitis C (HCV) infection. Although methadone maintenance may help to decrease HCV-related risk practices, HCV risk behaviors persist and are strongly associated with specific substance use patterns, mental status and social context. The ANRS-Methaville study gave us the opportunity to better disentangle the different relationships between these various factors and HCV risk practices. The ANRS-Methaville multisite randomized trial was designed to assess the feasibility of initiating methadone in primary care by comparing it with methadone initiation in specialized centers. This study recruited 195 participants initiating methadone maintenance and followed up for 12 months. Longitudinal data from this trial was used to acquire a greater understanding of HCV risk practices and their pattern of correlates in this population. We selected 176 patients who had data on HCV risk practices at M0 and M12, accounting for 312 visits. HCV risk practices were defined as follows: sharing needles or syringes, sharing drug paraphernalia, getting a tattoo or having a piercing in a non-professional context, sharing toiletry items. To identify factors associated with HCV risk practices, we performed a mixed logistic regression analysis. HCV risk practices were reported by 19% and 15% of participants at baseline and M12, respectively. After adjustment for age, cocaine use and alcohol dependence as well as suicidal risk, living in a couple with a non-drug user and in a couple with a drug user were both independent predictors of HCV risk practices (OR[CI95%] = 4.16 [1.42-12.12]; OR[CI95%] = 9.85 [3.13-31.06], respectively). Identifying individuals at risk of HCV transmission during methadone treatment such as stimulant users, alcohol dependent individuals, and those at suicidal risk is necessary to optimize response to treatment.

After adjustment for age, cocaine use and alcohol dependence as well as suicidal risk, living in a couple with a non-drug user and in a couple with a drug user were both independent predictors of HCV risk practices (OR[CI95%] = 4.16 [1.42-12.12]; OR[CI95%] = 9.85 [3.13-31.06], respectively). Conclusions Identifying individuals at risk of HCV transmission during methadone treatment such as stimulant users, alcohol dependent individuals, and those at suicidal risk is necessary to optimize response to treatment.

    Depressive symptoms often coexist with substance use disorders (SUDs). The DSM-IV has identified two distinct categories for depression coexisting with SUDs-independent depression and substance-induced depression. While this distinction has important therapeutic and prognostic implications, it remains difficult to make in clinical practice; the differentiation is often guided by chronological and symptom severity criteria that patients may be unable to precisely provide. Furthermore, it is unclear whether the various substances commonly abused-cannabis, cocaine, and opioids-are equally associated with the two types of depression. Predictors, associations, and other markers may be helpful in guiding the diagnostic process. We, therefore, examined the differences between cannabis-, cocaine-, and opioid-dependent individuals contending with independent depression and those contending with substance-induced depression in regard to several variables, hypothesizing that independent depression is more commonly found in females, and that it is associated with higher symptom severity and psychiatric comorbidity. Cocaine-, cannabis-, and/or opioid-dependent, treatment-seeking individuals underwent a structured clinical interview for DSM-IV-TR disorders after providing consent at our clinical research site; those with co-existing primary depression or substance-induced depression diagnoses were provided with further questionnaires and were entered into this analysis (n= 242). Pair-wise comparisons were conducted between the groups classified as independent versus substance-induced depression with 2-by-2 tables and chi-square tests for dichotomous independent variables, and t-tests for continuous variables. Binomial logistic regression was performed in order to ascertain which of the variables were significant predictors. Women were more likely than men to have independent depression (p< .005). Cannabis dependence was highly associated with independent depression (p< .001

    Genesis Medical Associates is an independent primary care practice in the suburbs of Pittsburgh. Given competitive pressures, a member of the physician leadership began thinking about the need for the practice to develop an "identity and awareness" program to set the practice apart from the competition. The idea for branding the campaign began when Dr. Rob Potter, Jr., was attending a Pittsburgh Pirates baseball game and a fan said to him, "You're that doctor I see on television" in the nursing home commercial. Triggered by this experience, Potter saw the opportunity to develop an awareness and identity campaign for Genesis. In this article we share the reasons for, the steps taken, and initial results in developing a medical practice branding strategy.

    Background There is considerable regional variation in Medicare outpatient visit rates; such variations may be the consequence of patient health, race/ethnicity differences, patient preferences, or physician supply and beliefs about the efficacy of frequently scheduled visits. Objective To test associations between varying regional Medicare outpatient visit rates and beneficiaries’ health, race/ethnicity, preferences, and physician practice norms and supply. Methods We used Medicare claims from 2006 and 2007, and data from national surveys of three different groups in 2005 – Medicare beneficiaries, cardiologists, and primary care physicians. Regression analysis tested explanations for outpatient visit rates: patient health (self-reported and hierarchical condition category (HCC) score), self-reported race/ethnicity, preferences for care, and local physician practice norms and supply in beneficiaries’ Hospital Referral Regions (HRRs) of residence. Results Beneficiaries in the highest quintile of HCC scores experienced 4.99 more visits than those in the lowest. Beneficiaries who were black experienced 2.14 fewer visits than others with similar health and preferences. Higher care-seeking preferences were marginally significantly associated with more visits, while education and poverty were insignificant. HRRs with high physician supply and high frequency practice norms were associated with 2.04 additional visits per year, while HRRs with high supply but low frequency norms were associated with 1.45 additional visits. Adjusting for all individual beneficiary covariates explained less than 20% of the original associations between visit rates and physician supply and practice norms. Conclusion Medicare beneficiaries’ health status, race, and preferences help explain individual office visit frequency; in particular, African-American patients appear to experience lower access to care. Yet, these factors explain a small fraction of the observed regional differences

    Yoga exercises have been associated with joint problems recently, indicating that yoga practice might be potentially dangerous for joint health. This study aimed to analyse whether regular yoga practice is associated with the frequency of joint problems in upper middle-aged Australian women. Women aged 62-67 years from the Australian Longitudinal Study on Women's Health (ALSWH) were questioned in 2013 whether they experienced regular joint pain or problems in the past 12 months and whether they regularly practiced yoga. Associations of joint problems with yoga practice were analysed using Chi-squared tests and multiple logistic regression modelling. Of 9151 women, 29.8% reported regular problems with stiff or painful joints, and 15.2, 11.9, 18.1 and 15.9% reported regular problems with shoulders, hips, knees and feet, respectively, in the past 12 months. Yoga was practiced sometimes by 10.1% and often by 8.4% of women. Practicing yoga was not associated with upper or lower limb joint problems. No association between yoga practice and joint problems has been identified. Further studies are warranted for conclusive judgement of benefits and safety of yoga in relation to joint problems.

    BACKGROUND: The organization and management of general practice is changing as a result of government policies designed to expand primary health care services. One aspect of practice management which has been underresearched concerns staffing: the recruitment, retention, management and motivation of practice managers. AIM: A study set out to find out who is routinely involved in making decisions about staffing matters in general practice, to establish the extent to which the human resource management function is formalized and specialized, and to describe the characteristics of the practice managers. METHOD: A postal questionnaire was sent to a stratified random sample of 750 general practices in England and Wales in February 1994 enquiring about the practice (for example, the fundholding status and number of general practitioner partners), how the practice dealt with a range of staffing matters and about the practice manager (for example, employment background and training in human resource management). Practices were classed as small (single-handed and two or three general practitioner partners), medium (four or five partners) or large (six or more partners). RESULTS: Replies were received from 477 practices (64%). Practice managers had limited authority to make decisions alone in the majority of practices although there was a greater likelihood of them taking independent action as the size of practice increased. Formality in handling staffing matters (as measured by the existence and use of written policies and procedures) also increased with practice size. Larger practices were more likely than smaller practices to have additional tiers in their management structure through the creation of posts with the titles assistant practice manager, fund manager and senior receptionist. Most practice managers had been recruited from within general practice but larger practices were more likely than smaller practices to recruit from outwith general practice. Three quarters

    Previous genome-wide association studies (GWAS), which were mainly based on single-variant analysis, have identified many systemic lupus erythematosus (SLE) susceptibility loci. However, the genetic architecture of this complex disease is far from being understood. The aim of this study was to investigate whether using a gene-based analysis may help to identify novel loci, by considering global evidence of association from a gene or a genomic region rather than focusing on evidence for individual variants. Based on the results of a meta-analysis of 2 GWAS of SLE conducted in 2 Asian cohorts, we performed an in-depth gene-based analysis followed by replication in a total of 4,626 patients and 7,466 control subjects of Asian ancestry. Differential allelic expression was measured by pyrosequencing. More than one-half of the reported SLE susceptibility loci showed evidence of independent effects, and this finding is important for understanding the mechanisms of association and explaining disease heritability. ANXA6 was detected as a novel SLE susceptibility gene, with several single-nucleotide polymorphisms (SNPs) contributing independently to the association with disease. The risk allele of rs11960458 correlated significantly with increased expression of ANXA6 in peripheral blood mononuclear cells from heterozygous healthy control subjects. Several other associated SNPs may also regulate ANXA6 expression, according to data obtained from public databases. Higher expression of ANXA6 in patients with SLE was also reported previously. Our study demonstrated the merit of using gene-based analysis to identify novel susceptibility loci, especially those with independent effects, and also demonstrated the widespread presence of loci with independent effects in SLE susceptibility genes. © 2015, American College of Rheumatology.

    The purpose of the current study was to utilise established scoring systems to analyse the association of (i) burn injury severity, (ii) comorbid status and (iii) associated systemic physiological disturbance with inpatient mortality in patients with severe burn injuries admitted to intensive care. Case notes of all patients with acute thermal injuries affecting ≥15% total body surface area (TBSA) admitted to the Burns Intensive Care Unit (BICU) at Chelsea and Westminster Hospital during a 10-year period were retrospectively reviewed. Revised Baux Score, Belgian Outcome in Burn Injury (BOBI) Score, Abbreviated Burn Severity Index (ABSI), APACHE II Score, Sequential Organ Failure Assessment (SOFA) Score and Updated Charlson Comorbidity Index (CCI) were computed for each patient and analysed for association with inpatient mortality. Ninety mechanically ventilated patients (median age 45.7 years, median % TBSA burned 36.5%) were included. 72 patients had full thickness burns and 35 patients had inhalational injuries. Forty-four patients died in hospital while 46 survived to discharge. In a multivariate logistic regression model, only the Revised Baux Score (p<0.001) and updated CCI (p=0.014) were independently associated with mortality. This gave a ROC curve with area under the curve of 0.920. On multivariate cox regression survival analysis, only the Revised Baux Score (p<0.001) and the updated CCI (p=0.004) were independently associated with shorter time to death. Our data suggest that the Revised Baux Score and the updated CCI are independently associated with inpatient mortality in patients admitted to intensive care with burn injuries affecting ≥15% TBSA. This emphasises the importance of comorbidities in the prognosis of patients with severe burn injuries. Copyright © 2015 Elsevier Ltd and ISBI. All rights reserved.

    We examined the association between negative and positive affect and 12-month health status in patients treated with percutaneous coronary intervention (PCI) with drug-eluting stents. Consecutive PCI patients (n = 562) completed the Global Mood Scale at baseline to assess affect and the EuroQoL-5D (EQ-5D) at baseline and 12-month follow-up to assess health status. Negative affect [F(1, 522) = 17.14, P < .001] and positive affect [F(1, 522) = 5.11, P = .02] at baseline were independent associates of overall health status at 12-month follow-up, adjusting for demographic and clinical factors. Moreover, there was a significant interaction for negative by positive affect [F(1, 522) = 6.11, P = .01]. In domain-specific analyses, high negative affect was associated with problems in mobility, self-care, usual activities, pain/discomfort, and anxiety/depression with the risk being two to fivefold. Low positive affect was only associated with problems in self-care (OR: 8.14; 95% CI: 1.85-35.9; P = .006) and usual activities (OR: 1.87; 95% CI: 1.17-3.00; P = .009). Baseline negative and positive affect contribute independently to patient-reported health status 12 months post PCI. Positive affect moderated the detrimental effects of negative affect on overall health status. Enhancing positive affect might be an important target to improve patient-centered outcomes in coronary artery disease.

    The purpose of our study was to determine the predictive impact of individual academic measures for the matriculation of senior medical students into a general surgery residency. Academic records were evaluated for third-year medical students (n = 781) at a single institution between 2004 and 2011. Cohorts were defined by student matriculation into either a general surgery residency program (n = 58) or a non-general surgery residency program (n = 723). Multivariate logistic regression was performed to evaluate independently significant academic measures. Clinical evaluation raw scores were predictive of general surgery matriculation (P = .014). In addition, multivariate modeling showed lower United States Medical Licensing Examination Step 1 scores to be independently associated with matriculation into general surgery (P = .007). Superior clinical aptitude is independently associated with general surgical matriculation. This is in contrast to the negative correlation United States Medical Licensing Examination Step 1 scores have on general surgery matriculation. Recognizing this, surgical clerkship directors can offer opportunities for continued surgical education to students showing high clinical aptitude, increasing their likelihood of surgical matriculation.

    To comprehensively evaluate the independent associations and potential interactions of vitamin D-related biomarkers including total and bioavailable 25-hydroxyvitamin D (25OHD), VDBP (vitamin D binding protein), and parathyroid hormone (PTH) with risk of coronary heart disease (CHD). We prospectively identified incident cases of nonfatal myocardial infarction and fatal CHD among women in the Nurses' Health Study during 20 years of follow-up (1990-2010). Using risk-set sampling, 1 to 2 matched controls were selected for each case. The analysis of 25OHD and PTH included 382 cases and 575 controls; the analysis of VDBP included 396 cases and 398 controls. After multivariate adjustment, plasma levels of total 25OHD, bioavailable 25OHD, and PTH were not significantly associated with CHD risk. VDBP was associated with a lower CHD risk with an extreme-quartile odds ratio of 0.60 (95% confidence interval, 0.39-0.92; P trend=0.02). When examining the biomarkers jointly, a significant, inverse association between 25OHD and CHD was observed among participants with higher PTH levels ( P for interaction=0.02). The odds ratio (95% confidence interval) comparing the highest quartile of 25OHD to lowest was 0.43 (0.23-0.82; P trend=0.003) when PTH levels were above population median (35.3 pg/mL), whereas among the rest of participants the corresponding odds ratio (95% confidence interval) was 1.28 (0.70-2.36; P trend=0.43). Our data suggest that higher 25OHD levels were associated with a lower CHD risk when PTH levels were high, whereas no association was observed for participants with low PTH levels. VDBP but not bioavailable 25OHD was independently associated with lower CHD risk. © 2017 American Heart Association, Inc.

    Background The effect of pregnancy intention on post-natal practices like breastfeeding is still poorly understood in the Philippines. In this light, this study aims to determine the association between pregnancy intention and optimal breastfeeding practices in the Philippines. Methods This is a cross-sectional study design using the 2003 Philippine National Demographic and Health Survey. Logistic regression analysis was used to determine the independent association of pregnancy intention and optimal breastfeeding practices. The study includes 3,044 last-born children aged 6–36 months at the time of survey. Dead children were also included as long as their age of death satisfies the age criterion. Results Children born from mistimed pregnancies are more likely to have late breastfeeding initiation compared to children born from wanted pregnancies (OR = 1.44; 90%CI: 1.17-1.78). However, this occurs only among children belonging to households with low socio-economic status. Among children belonging to households with high socio-economic status, no significant effect of pregnancy intention on breastfeeding initiation was observed. Children born from unwanted pregnancies are less likely to have short breastfeeding duration (OR = 0.60; 90%CI: 0.48-0.76). However, this occurs only among children belonging to households with high socioeconomic status. No significant effect of pregnancy intention on breastfeeding duration was observed among children belonging to households with low socio-economic status. Conclusion The findings of this study suggest that there are different effects of pregnancy intention on the two types of optimal breastfeeding practices examined. With regards to breastfeeding duration, it was found that among infants belonging to high SES, the odds of having short breastfeeding duration is lower among children born from unwanted pregnancies compared to children born from wanted one. Conversely, children belonging to low SES household, the

    Schools are important settings for not only providing and promoting children's physical activity (PA) but also for reducing PA disparities. We investigated associations between school-level demographic characteristics (racial/ethnic and socioeconomic composition, urban-rural status, and student-to-teacher ratio) and 16 PA-promoting practices in 347 Nevada public elementary, middle, and high schools in 2014. We found that low-cost and easy-to-implement practices are most prevalent. There is relative demographic equity in ten of 16 PA practices and significant differences in six PA practices in Nevada schools. Schools with comparatively larger percentages of Black students are the most disadvantaged, as they have the fewest PA-supportive practices in place. Higher percent black was associated with lower odds of providing classroom activity breaks (AOR=0.632, 95% CI=0.453-0.881) and bike racks (AOR=0.60, 95% CI=0.362-0.996), greater odds of withholding recess/PE for disciplinary reasons (AOR=1.377, 95% CI=1.006-1.885), and lower odds of having recess supervisors who are trained to promote PA (AOR=0.583, 95% CI=0.374-0.909). Schools with greater percentages of Hispanic students have lower odds of providing before-school PA programs (AOR=0.867, 95% CI=0.761-0.987), whereas schools with greater percentages of low-SES students have greater odds of providing after-school PA programs (AOR=1.135, 95% CI=1.016-1.268). Higher student-to-teacher ratio was also associated with greater odds of providing after-school PA programs (AOR=1.135, 95% CI=1.016-1.268). Urban-rural status was unrelated to all PA practices.

    The use of out-of-hours healthcare services for non-urgent health problems is believed to be related to the organisation of daytime primary care but insight into underlying mechanisms is limited. Our objective was to examine the association between daytime general practice characteristics and the use of out-of-hours care GP cooperatives. A cross-sectional observational study in 100 general practices in the Netherlands, connected to five GP cooperatives. In each GP cooperative, we took a purposeful sample of the 10 general practices with the highest use of out-of-hours care and the 10 practices with the lowest use. Practice and population characteristics were obtained by questionnaires, interviews, data extraction from patient registration systems and telephone accessibility measurements. To examine which aspects of practice organisation were associated with patients' use of out-of-hours care, we performed logistic regression analyses (low versus high out-of-hours care use), correcting for population characteristics. The mean out-of-hours care use in the high use group of general practices was 1.8 times higher than in the low use group. Day time primary care practices with more young children and foreigners in their patient populations and with a shorter distance to the GP cooperative had higher out-of-hours primary care use. In addition, longer telephone waiting times and lower personal availability for palliative patients in daily practice were associated with higher use of out-of-hours care. Moreover, out-of-hours care use was higher when practices performed more diagnostic tests and therapeutic procedures and had more assistant employment hours per 1000 patients. Several other aspects of practice management showed some non-significant trends: high utilising general practices tended to have longer waiting times for non-urgent appointments, lower availability of a telephone consulting hour, lower availability for consultations after 5 p.m., and less frequent

    The home and community care sector is one of the fastest growing sectors globally and most prominently in mature industrialized countries. Personal support workers (PSWs) are the largest occupational group in the sector. This paper focuses on the emotional health of PSWs working in the home and community care sector in Ontario, Canada. The purpose of this paper is to present evidence on the associations between PSWs' life and work stress and organizational practices of full-time and guaranteed hours, and PSWs' perceptions of support at work and preference for hours. Data come from our 2015 survey of 1543 PSWs. Dependent variables are life and work stress. Independent variables are: objective organizational practices of full-time and guaranteed hours, and subjective organizational practices of perceived support at work, and preferred hours of work. Descriptive statistics, correlations and ordinary least square regression analyses with collinearity tests are conducted. Organizational practices of employing PSWs in full-time or guaranteed hours are not associated with their life and work stress. However, those who perceive support from their organizations are also the ones reporting lower life and work stress. In addition, those PSWs perceiving support from their supervisor report lower work stress. PSWs would like to work in their preferred hours, and those who prefer to work more hours report lower life and work stress, and conversely, those who prefer to work less hours report life and work stress. For PSWs in home and community care, perceived support from their organizations and supervisors, and employment in preferred hours are important factors related to their life and work stress.

    Modern transportation networks have facilitated the migration and mingling of previously isolated populations of plants, animals, and insects. Human activities can also influence the global distribution of microorganisms. The best-understood example is yeasts associated with winemaking. Humans began making wine in the Middle East over 9,000 years ago [1, 2]. Selecting favorable fermentation products created specialized strains of Saccharomyces cerevisiae [3, 4] that were transported along with grapevines. Today, S. cerevisiae strains residing in vineyards around the world are genetically similar, and their population structure suggests a common origin that followed the path of human migration [3-7]. Like wine, coffee and cacao depend on microbial fermentation [8, 9] and have been globally dispersed by humans. Theobroma cacao originated in the Amazon and Orinoco basins of Colombia and Venezuela [10], was cultivated in Central America by Mesoamerican peoples, and was introduced to Europeans by Hernán Cortés in 1530 [11]. Coffea, native to Ethiopia, was disseminated by Arab traders throughout the Middle East and North Africa in the 6(th) century and was introduced to European consumers in the 17(th) century [12]. Here, we tested whether the yeasts associated with coffee and cacao are genetically similar, crop-specific populations or genetically diverse, geography-specific populations. Our results uncovered populations that, while defined by niche and geography, also bear signatures of admixture between major populations in events independent of the transport of the plants. Thus, human-associated fermentation and migration may have affected the distribution of yeast involved in the production of coffee and chocolate. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The aim of this study was to investigate possible association between migraine and physical practice among 480 medical students who were submitted to a questionnaire about headaches and physical practices. Migraine diagnosis was assessed by ID-Migraine and functional disability was evaluated with MIDAS. The type (aerobic or strength training), the weekly frequency and the intensity of physical practice and body mass index (BMI) were assessed. There was a reduction in functional disability of migraine in students reporting physical practice (no physical practice - MIDAS=8.81±1.40, physical practice - MIDAS=15.49±1.78; P=0.03). Frequency, intensity, and type of physical practices were not associated with functional impact of migraine. BMI did not correlate with migraine impact (normal weight - MIDAS=12.34±1.33, overweight or obese - MIDAS=17.45±3.86; P=0.33). These results were confirmed by multivariate analysis. Our data suggest that physical practice is inversely related with functional disability of migraine in university students regardless of BMI.

    The kidney is easily affected by aging-associated changes, including glomerulosclerosis, tubular atrophy, and interstitial fibrosis. Particularly, renal tubulointerstitial fibrosis is a final common pathway in most forms of progressive renal disease. Angiotensin II type 1 receptor (AT1R)-associated protein (ATRAP), which was originally identified as a molecule that binds to AT1R, is highly expressed in the kidney. Previously, we have shown that ATRAP suppresses hyperactivation of AT1R signaling, but does not affect physiological AT1R signaling. We hypothesized that ATRAP has a novel functional role in the physiological age-degenerative process, independent of modulation of AT1R signaling. ATRAP-knockout mice were used to study the functional involvement of ATRAP in the aging. ATRAP-knockout mice exhibit a normal age-associated appearance without any evident alterations in physiological parameters, including blood pressure and cardiovascular and metabolic phenotypes. However, in ATRAP-knockout mice compared with wild-type mice, the following takes place: (1) age-associated renal function decline and tubulointerstitial fibrosis are more enhanced; (2) renal tubular mitochondrial abnormalities and subsequent increases in the production of reactive oxygen species are more advanced; and (3) life span is 18.4% shorter (median life span, 100.4 versus 123.1 weeks). As a key mechanism, age-related pathological changes in the kidney of ATRAP-knockout mice correlated with decreased expression of the prosurvival gene, Sirtuin1 . On the other hand, chronic angiotensin II infusion did not affect renal sirtuin1 expression in wild-type mice. These results indicate that ATRAP plays an important role in inhibiting kidney aging, possibly through sirtuin1-mediated mechanism independent of blocking AT1R signaling, and further protecting normal life span. © 2017 The Authors.

    Cardiac troponins (cTn) are to date the most sensitive and specific biochemical markers of myocardial injury. Abnormal breathing patterns in patients with obstructive sleep apnea (OSA) may cause myocardial cell stress detectable by novel cTn assays. The objectives of this study were to investigate whether a new single-molecule cTnI (S-cTnI) assay and a commercially available high-sensitivity cTnT (hs-cTnT) assay would detect myocyte injury in individuals evaluated for possible OSA, and to explore their relation to variables of disordered breathing during sleep. Consecutive individuals referred to Lovisenberg Diakonale Hospital's sleep laboratory between 1 October 2009 and 1 March 2010 were included. We measured cTn in specimens collected the morning after sleep and studied these in relation to variables recorded during polygraphy or polysomnography. All 222 (100 %) individuals had measurable cTn levels using either assay. Stratified into categories according to the apnea-hypopnea index (AHI), patients with OSA (AHI ≥5) had a different distribution of S-cTnI (P = 0.036) and hs-cTnT (P = 0.002) compared to those without (AHI <5). The median (quartiles 1-3) were 3.0 (1.9-6.0) versus 2.3 (1.6-3.8) ng/l for S-cTnI, and 7.0 (5.5-8.7) versus 6.2 (4.9-7.2) ng/l for hs-cTnT. However, in multiple median regression analyses adjusted for conventional predictors, neither S-cTnI (P = 0.57) nor hs-cTnT (P = 0.80) were significantly associated with AHI. This study reveals no association independent of conventional predictors between OSA and myocardial cell injury measured by S-cTnI and hs-cTnT assays. Our findings support a search for novel biomarkers for prognostication of OSA.

    Background With the high prevalence of musculoskeletal disorders (MSDs) for patient care unit workers, prevention efforts through ergonomic practices within units may be related to symptoms associated with typical work-related MSDs. Methods We completed a cross-sectional survey of patient care workers (n=1572) in two large academic hospitals in order to evaluate relationships between self-reported musculoskeletal pain, work interference due to this pain, and limitations during activities of daily living (functional limitations) and with ergonomic practices and other organizational policy and practices metrics within the unit. Bivariate and multiple logistic regression analyses tested the significance of these associations. Results Prevalence of self-reported musculoskeletal symptoms in the past 3-months was 74% with 53% reporting pain in the low back. 32.8% reported that this pain interfered with their work duties and 17.7% reported functional limitations in the prior week. Decreased ergonomic practices were significantly associated with reporting pain in four body areas (low back, neck/shoulder, arms, and lower extremity) in the previous 3-months, interference with work caused by this pain, symptom severity and limitations in completing activities of daily living in the past week. Except for low back pain and work interference, these associations remained significant when psychosocial covariates such as psychological demands were included in multiple logistic regressions, Conclusions Ergonomic practices appear to be associated with many of the musculoskeletal symptoms denoting their importance for prevention efforts in acute health care settings.

    The study objective was to evaluate independent and interactive associations of dietary fiber intake and high urinary enterolignans with cardiometabolic risk factors. The analysis included 2260 adults (≥20 y of age) from the 2003-2010 NHANES. Logistic regression models were used to evaluate obesity and clinically defined cardiometabolic risk factors in relation to dietary fiber intake and urinary enterolignan concentrations. Three sets of models were created: 1) independent associations, 2) mutually adjusted associations, and 3) interactions. Models were adjusted for age, gender, race/ethnicity, education, smoking status, and energy intake. High concentrations were considered to be above the 90th percentile of urinary enterolignan concentrations. Increasing dietary fiber intake was associated with high blood pressure (P = 0.02) and low serum HDL cholesterol (P-trend = 0.03). High urinary enterodiol concentration was not associated with obesity or cardiometabolic risk factors. High urinary enterolactone concentration was inversely associated with obesity (OR: 0.44; 95% CI: 0.29, 0.66), abdominal obesity (OR: 0.58; 95% CI: 0.39, 0.87), high serum C-reactive protein (CRP; OR: 0.52; 95% CI: 0.37, 0.74), high serum triglycerides (OR: 0.39; 95% CI: 0.23, 0.61), low serum HDL cholesterol (OR: 0.37; 95% CI: 0.23, 0.61), and metabolic syndrome (OR: 0.47; 95% CI: 0.30, 0.74). In mutually adjusted models, enterolactone associations observed in independent models remained similar, but associations for dietary fiber intake were attenuated, with the exception of blood pressure. In interaction models, there were 2 significant interactions: between high urinary enterodiol concentration and dietary fiber intake for high serum CRP (P = 0.04) and high plasma glucose (P = 0.04). Overall, being in the highest 10% of urinary enterolactone concentration was associated with cardiometabolic risk factors, independent of dietary fiber intake and enterodiol concentration.

    Schools are important settings for not only providing and promoting children's physical activity (PA) but also for reducing PA disparities. We investigated associations between school-level demographic characteristics (racial/ethnic and socioeconomic composition, urban-rural status, and student-to-teacher ratio) and 16 PA-promoting practices in 347 Nevada public elementary, middle, and high schools in 2014. We found that low-cost and easy-to-implement practices are most prevalent. There is relative demographic equity in ten of 16 PA practices and significant differences in six PA practices in Nevada schools. Schools with comparatively larger percentages of Black students are the most disadvantaged, as they have the fewest PA-supportive practices in place. Higher percent black was associated with lower odds of providing classroom activity breaks (AOR=0.632, 95% CI=0.453-0.881) and bike racks (AOR=0.60, 95% CI=0.362-0.996), greater odds of withholding recess/PE for disciplinary reasons (AOR=1.377, 95% CI=1.006-1.885), and lower odds of having recess supervisors who are trained to promote PA (AOR=0.583, 95% CI=0.374-0.909). Schools with greater percentages of Hispanic students have lower odds of providing before-school PA programs (AOR=0.867, 95% CI=0.761-0.987), whereas schools with greater percentages of low-SES students have greater odds of providing after-school PA programs (AOR=1.135, 95% CI=1.016-1.268). Higher student-to-teacher ratio was also associated with greater odds of providing after-school PA programs (AOR=1.135, 95% CI=1.016-1.268). Urban-rural status was unrelated to all PA practices.

    Utilization of cardiac services varies across regions and hospitals, yet little is known regarding variation in the intensity of outpatient cardiac care across cardiology physician practices or the association with clinical endpoints, an area of potential importance to promote efficient care. We included 7 160 732 Medicare beneficiaries who received services from 5635 cardiology practices in 2012. Beneficiaries were assigned to practices providing the plurality of office visits, and practices were ranked and assigned to quartiles using the ratio of observed to predicted annual payments per beneficiary for common cardiac services (outpatient intensity index). The median (interquartile range) outpatient intensity index was 1.00 (0.81-1.24). Mean payments for beneficiaries attributed to practices in the highest (Q4) and lowest (Q1) quartile of outpatient intensity were: all cardiac payments (Q4 $1272 vs Q1 $581; ratio, 2.2); cardiac catheterization (Q4 $215 vs Q1 $64; ratio, 3.4); myocardial perfusion imaging (Q4 $253 vs Q1 $83; ratio, 3.0); and electrophysiology device procedures (Q4 $353 vs Q1 $142; ratio, 2.5). The adjusted odds ratios (95% CI) for 1 incremental quartile of outpatient intensity for each outcome was: cardiac surgical/procedural hospitalization (1.09 [1.09, 1.10]); cardiac medical hospitalization (1.00 [0.99, 1.00]); noncardiac hospitalization (0.99 [0.99, 0.99]); and death at 1 year (1.00 [0.99, 1.00]). Substantial variation in the intensity of outpatient care exists at the cardiology practice level, and higher intensity is not associated with reduced mortality or hospitalizations. Outpatient cardiac care is a potentially important target for efforts to improve efficiency in the Medicare population. © 2016 The Authors.

    Information on vaginal-related issues among Malaysian women is very limited. This study aimed to explore factors associated with preventive practices of vaginitis among Malaysian women. A cross-sectional computer-assisted telephone interview survey of a representative sample of multi-racial Malaysian women aged 18-50 years old was conducted from January to April 2014. Women from 1446 households responded to the survey and nearly one-third (32.1%) reported to have experienced vaginitis. In multivariate analyses, respondents in the urban locality were more likely to practice vaginitis prevention (OR = 1.40, 95% CI = 1.06-1.84) compared with those in the rural areas. Respondents who perceived low susceptibility to vaginitis were less likely to practice vaginitis prevention (OR = 0.72, 95% CI = 0.57-0.91) compared with responders who highly perceive susceptibility. Respondents who had no formal education were less likely to practice vaginitis prevention (OR = 0.16, 95% CI = 0.05-0.48) compared with those with tertiary education. This study showed that comprehensive education and health programmes need to focus on women with a low educational level, living in rural areas and women with low perceived susceptibility to vaginitis. Impact statement What is already known on this subject? Little is known about vaginitis issues among women in Malaysia. This study provides information regarding vaginitis among Malaysian women by looking at the factors associated with prevention practices. What do the results of this study add? From our study, factors associated with prevention practices were found to be educational level, locality, and perceived susceptibility of vaginitis. Those who perform fewer vaginitis prevention practices were women with a low educational level and those who live in rural areas. From the Health Belief Model, women with a low perceived susceptibility of vaginitis were less likely to carry out vaginitis prevention practices. What are

    Studies have suggested differential associations of specific indicators of socioeconomic position (SEP) with nutrient intake and a cumulative effect of these indicators on diet. We investigated the independent association of SEP indicators (education, income, occupation) with nutrient intake and their effect modification. This cross-sectional analysis included 91,900 French adults from the NutriNet-Santé cohort. Nutrient intake was estimated using three 24-h records. We investigated associations between the three SEP factors and nutrient intake using sex-stratified analysis of covariance, adjusted for age and energy intake, and associations between income and nutrient intake stratified by education and occupation. Low educated participants had higher protein and cholesterol intakes and lower fibre, vitamin C and beta-carotene intakes. Low income individuals had higher complex carbohydrate intakes, and lower magnesium, potassium, folate and vitamin C intakes. Intakes of vitamin D and alcohol were lower in low occupation individuals. Higher income was associated with higher intakes of fibre, protein, magnesium, potassium, beta-carotene, and folate among low educated persons only, highlighting effect modification. Lower SEP, particularly low education, was associated with lower intakes of nutrients required for a healthy diet. Each SEP indicator was associated with specific differences in nutrient intake suggesting that they underpin different social processes. PMID:26978393

    To explore the associations of vitamin D status and obesity with insulin resistance (IR) in children. A sample of 2282 schoolchildren (9-13 years old) in Greece was examined. Sociodemographic, anthropometric (weight, height), biochemical (fasting plasma glucose, serum insulin and 25(OH)D), pubertal status and physical activity data were collected, using standard methods. The "Vitamin D Standardization Program" protocol was applied to standardize serum 25(OH)D values. The prevalence of vitamin D insufficiency (serum 25(OH)D < 50 nmol/L) was higher in obese children compared to their over- and normal-weight counterparts (60.5% vs 51.6% and 51%, P = .017). Furthermore, children with IR (both obese and non-obese) had higher prevalence of vitamin D insufficiency compared to non-obese, non-insulin resistant children (66% and 59.2% vs 49.8%, P < .05), possibly indicating that IR is associated with vitamin D insufficiency, independently of obesity. In line with the above, the results from logistic regression analyses controlled for several potential confounders, showed a 1.48 (95% C.I: 1.2-1.84) higher likelihood for vitamin D insufficiency for insulin resistant children compared to the non-insulin resistant ones, while no significant association was observed with obesity. The present study revealed a high prevalence of vitamin D insufficiency among schoolchildren in Greece, particularly among obese and insulin resistant ones. In addition, it highlighted that the significant association of vitamin D insufficiency with IR is possibly independent of obesity. Further clinical trials are needed to confirm this possible independent association but also explore the potential beneficial effect of vitamin D supplementation on IR and possibly on weight management too. © 2018 John Wiley & Sons A/S.

    Appropriate selection of patients is key to the success of care management programs (CMPs). Hybrid patient selection approaches, in which large data assets are culled to develop a list of patients for more targeted clinical review, are increasingly common. We sought to describe the patient and practice characteristics associated with high-risk patient identification and selection for a CMP during clinical review, and to explore variation across primary care practices. Retrospective cohort study. Standardized estimates of Medicare beneficiaries identified as high risk for poor outcomes and high medical expense, and appropriate for a CMP within a large Pioneer Accountable Care Organization, were developed using mixed effects logistic models. Study subjects were 2685 Medicare beneficiaries aged over 18 (includes individuals eligible for Medicare due to a disability) aligned to 35 primary care practices in 2013. Independent predictors of patient identification as high risk include older age; higher risk score; recent increases in medical conditions; higher numbers of medical hospitalizations, skilled nursing facility days, and primary care physician visits; and shorter relationships with the primary care physician. Older age, and lower income, but no prior hospice use were independently associated with patient selection for a CMP among the subset of patients identified as being high risk. Adjusted predicted percents of high-risk patients varied significantly across practices overall and for 5 of the 6 patient characteristics that were independently associated with identification as high risk. Inconsistency in high-risk patient identification and selection for a CMP may reflect differences in practice resources, but also highlight the need for continual training and feedback in order to protect against unintentional biases.

    Physician associates (PAs) are described as one solution to workforce capacity in primary care in the UK. Despite new investment in the role, how effective this will be in addressing unmet primary care needs is unclear. To investigate the barriers and facilitators to the integration of PAs into the general practice workforce. A modified grounded theory study in a region unfamiliar with the PA role. No a priori themes were assumed. Themes generated from stakeholder interviews informed a literature review and theoretical framework, and were then tested in focus groups with GPs, advanced nurse practitioners (ANPs), and patients. Recorded data were transcribed verbatim, and organised using NVivo version 10.2.2, with iterative analysis of emergent themes. A reflexive diary and independent verification of coding and analysis were included. There were 51 participants (30 GPs, 11 ANPs, and 10 patients) in eight focus groups. GPs, ANPs, and patients recognised that support for general practice was needed to improve access. GPs expressed concerns regarding PAs around managing medical complexity and supervision burden, non-prescriber status, and medicolegal implications in routine practice. Patients were less concerned about specific competencies as long as there was effective supervision, and were accepting of a PA role. ANPs highlighted their own negative experiences entering advanced clinical practice, and the need for support to counteract stereotypical and prejudicial attitudes CONCLUSION: This study highlights the complex factors that may impede the introduction of PAs into UK primary care. A conceptual model is proposed to help regulators and educationalists support this integration, which has relevance to other proposed new roles in primary care. © British Journal of General Practice 2017.

    A cornerstone of the recent consensus statements on concussion is a multifaceted concussion-assessment program at baseline and postinjury and when tracking recovery. Earlier studies of athletic trainers' (ATs') practice patterns found limited use of multifaceted protocols; however, these authors typically grouped diverse athletic training settings together. To (1) describe the concussion-management practice patterns of National Collegiate Athletic Association (NCAA) Division I ATs, (2) compare these practice patterns to earlier studies, and (3) objectively characterize the clinical examination. Cross-sectional study. Online survey. A total of 610 ATs from NCAA Division I institutions, for a response rate of 34.4%. The survey had 3 subsections: demographic questions related to the participant's experiences, concussion-assessment practice patterns, and concussion-recovery and return-to-participation practice patterns. Specific practice-pattern questions addressed balance, cognitive and mental status, neuropsychological testing, and self-reported symptoms. Finally, specific components of the clinical examination were examined. We identified high rates of multifaceted assessments (i.e., assessments using at least 3 techniques) during testing at baseline (71.2%), acute concussion assessment (79.2%), and return to participation (66.9%). The specific techniques used are provided along with their adherence with evidence-based practice findings. Respondents endorsed a diverse array of clinical examination techniques that often overlapped objective concussion-assessment protocols or were likely used to rule out associated potential conditions. Respondents were cognizant of the Third International Consensus Statement, the National Athletic Trainers' Association position statement, and the revised NCAA Sports Medicine Handbook recommendations. Athletic trainers in NCAA Division I demonstrated widespread use of multifaceted concussion-assessment techniques and appeared

    Concentration among physician groups has been steadily increasing, which may affect prices for physician services. We assessed the relationship in 2010 between physician competition and prices paid by private preferred provider organizations for fifteen common, high-cost procedures to understand whether higher concentration of physician practices and accompanying increased market power were associated with higher prices for services. Using county-level measures of the concentration of physician practices and county average prices, and statistically controlling for a range of other regional characteristics, we found that physician practice concentration and prices were significantly associated for twelve of the fifteen procedures we studied. For these procedures, counties with the highest average physician concentrations had prices 8-26 percent higher than prices in the lowest counties. We concluded that physician competition is frequently associated with prices. Policies that would influence physician practice organization should take this into consideration.

    Background Pharmaceutical company representatives likely influence the prescribing habits and professional behaviors of physicians. The objective of this study was to systematically review the association between physicians’ interactions with pharmaceutical companies and their clinical practices. Methods We used the standard systematic review methodology. Observational and experimental study designs examining any type of targeted interaction between practicing physicians and pharmaceutical companies were eligible. The search strategy included a search of MEDLINE and EMBASE databases up to July 2016. Two reviewers selected studies, abstracted data, and assessed risk of bias in duplicate and independently. We assessed the quality of evidence using the GRADE approach. Results Twenty articles reporting on 19 studies met our inclusion criteria. All of these studies were conducted in high-income countries and examined different types of interactions, including detailing, industry-funded continuing medical education, and receiving free gifts. While all included studies assessed prescribing behaviors, four studies also assessed financial outcomes, one assessed physicians’ knowledge, and one assessed their beliefs. None of the studies assessed clinical outcomes. Out of the 19 studies, 15 found a consistent association between interactions promoting a medication, and inappropriately increased prescribing rates, lower prescribing quality, and/or increased prescribing costs. The remaining four studies found both associations and lack of significant associations for the different types of exposures and drugs examined in the studies. A meta-analysis of six of these studies found a statistically significant association between exposure and physicians’ prescribing behaviors (OR = 2.52; 95% CI 1.82–3.50). The quality of evidence was downgraded to moderate for risk of bias and inconsistency. Sensitivity analysis excluding studies at high risk of bias did not substantially

    Depression, anxiety, and inflammation are common in polycystic ovary syndrome (PCOS). Inflammation may adversely impact on mood and vitamin D has been associated with both mood disorders and inflammation in the general population, but these relationships have not been studied in PCOS. The aim of this study was to investigate the association among 25 hydroxy-Vitamin D (25OHVD) status, anxiety, depression, and inflammation in women with and without PCOS. Cross-sectional study in overweight or obese premenopausal women with (n = 50) and without (n = 23) PCOS. Primary outcome measures were 25OHVD, mood (Hospital Anxiety and Depression questionnaire), and inflammation (highly sensitive C-reactive protein (hsCRP)). Vitamin D deficiency (25OHVD<50 nmol/L) (46% versus 39%, p = 0.311) and 25OHVD (50.4 ± 22.2 nmol/L versus 51.6 ± 19.0 nmol/L, p = 0.828) were not significantly different in women with and without PCOS. For all women combined, 25OHVD was the only significant independent predictor of depression (β = -0.063 ± 0.021, p = 0.005) and hsCRP (β = -0.041 ± 0.015, p = 0.010). Vitamin D deficiency is common in both women with and without PCOS with no differences between the groups. Vitamin D is independently associated with depression and inflammation in overweight women both with and without PCOS. Further investigation to clarify the interrelationship among vitamin D, inflammation and depression is required to identify optimal prevention and treatment strategies for psychological and metabolic dysfunction in PCOS.

    Irisin, a newly discovered adipo-myokine, is implicated in the modulation of the adipose phenotype, increasing energy expenditure and ameliorating systemic metabolism. Our aim was to investigate circulating irisin in subclinical hypothyroidism (SH) and study its associations with cardiometabolic risk factors. In a large case-control study, serum irisin, insulin resistance and lipid parameters, classic adipokines, inflammatory and hepatic biomarkers, and cardiovascular risk factors were determined in 120 consecutive patients with SH and 120 healthy controls matched on age, gender, and date of blood draw. Sixteen patients with SH received L-T4 treatment and, after 6 months, serum irisin and other biomarkers were assessed. SH cases exhibited significantly higher circulating irisin than controls (p < 0.001). In all participants, irisin was positively associated with TSH, anti-TG, HOMA-IR, C-peptide, lipid and inflammatory biomarkers, leptin, and cardiovascular risk factors, including Framigham score and apolipoprotein B/apolipoprotein A-I. Irisin was negatively correlated with adiponectin, HDL-C, and thyroid hormones. Serum irisin was independently associated with SH, above and beyond body mass index and cardiometabolic factors (p = 0.02). TSH was an independent predictor of circulating irisin (p = 0.003). L-T4 therapy did not reverse considerably the hyperirisinemic status in treated SH patients (p = 0.09). Irisin may represent an adipo-myokine counterbalancing a potential, gradual deterioration of lipid metabolism and insulin sensitivity in SH as well as reflecting a protective compensatory mechanism against oxidative muscle and thyroid cell stress. More mechanistic and prospective studies shedding light on the pathogenetic role of irisin in SH are needed to confirm and extend these data.

    This study tested the association between parent illicit drug use disorder (DUD) in early adulthood and observed parenting practices at ages 27-28 and examined the following 3 theoretically derived models explaining this link: (a) a disrupted parent adult functioning model,(b) a preexisting parent personality factor model, and (c) a disrupted adolescent family process model. Associations between study variables and child externalizing problems also were examined. Longitudinal data linking 2 generations were drawn from the Seattle Social Development Project (SSDP) and The SSDP Intergenerational Project (TIP), and included 167 parents and their 2- to 8-year-old child. Path modeling revealed that parent DUD in early adulthood predicted later observed low-skilled parenting, which was related to child externalizing problems. The preexisting parent personality factor model was supported. Parent negative emotionality accounted for the association between parent early adult DUD and later parenting practices. Parent negative emotionality also was related directly to child externalizing behavior. Limited support for the disrupted transition to adulthood model was found. The disrupted adolescent family process model was not supported. Results suggest that problem drug use that occurs early in adulthood may affect later parenting skills, independent of subsequent parent drug use. Findings highlight the importance of parent negative emotionality in influencing his or her own problem behavior, interactions with his or her child, and his or her child's problem behavior. Prevention and treatment programs targeting young adult substance use, poor parenting practices, and child behavior problems should address parent personality factors that may contribute to these behaviors.

    Little data exist regarding clinicians' role in the rising annual incidence rate of cesarean delivery in the US. We aimed to examine if clinicians' practice environment is associated with recommending cesarean deliveries. This is a survey study of clinicians who practice obstetrics in the US. This survey included eight clinical vignettes and 27 questions regarding clinicians' practice environment. Chi-square test and multivariable logistic regression were used for statistical comparison. Of 27 675 survey links sent, 3646 clinicians received and opened the survey electronically, and 1555 (43%) participated and 1486 (94%) completed the survey. Clinicians were categorized into three groups based on eight common obstetric vignettes as: more likely (n = 215), average likelihood (n = 1099), and less likely (n = 168) to recommend cesarean. Clinician environment factors associated with a higher likelihood of recommending cesarean included Laborists/Hospitalists practice model (p < 0.001), as-needed anesthesia support (p = 0.003), and rural/suburban practice setting (p < 0.001). We identified factors in clinicians' environment associated with their likelihood of recommending cesarean delivery. The decision to recommend cesarean delivery is a complicated one and is likely not solely based on patient factors.

  15. Associations between motor timing, music practice, and intelligence studied in a large sample of twins.

    Music performance depends critically on precise processing of time. A common model behavior in studies of motor timing is isochronous serial interval production (ISIP), that is, hand/finger movements with a regular beat. ISIP accuracy is related to both music practice and intelligence. Here we present a study of these associations in a large twin cohort, demonstrating that the effects of music practice and intelligence on motor timing are additive, with no significant multiplicative (interaction) effect. Furthermore, the association between music practice and motor timing was analyzed with the use of a co-twin control design using intrapair differences. These analyses revealed that the phenotypic association disappeared when all genetic and common environmental factors were controlled. This suggests that the observed association may not reflect a causal effect of music practice on ISIP performance but rather reflect common influences (e.g., genetic effects) on both outcomes. The relevance of these findings for models of practice and expert performance is discussed. © 2014 New York Academy of Sciences.

    In Canada, little is known about how food parenting practices are associated with young children's dietary intakes and no studies have examined food parenting practices of Canadian fathers. This study aimed to examine associations between food parenting practices and preschool-age children's nutrition risk. We conducted a cross-sectional analysis of thirty-one 2-parent families; 31 mothers, 31 fathers, and 40 preschool-age children. Parents completed an adapted version of the Comprehensive Feeding Practices Questionnaire. We calculated children's nutrition risk using their NutriSTEP score. To account for sibling association, we used generalized estimating equations, adjusting for child age, sex, household income, and parental body mass index. Both mothers' and fathers' involvement of children in meal preparation were associated with lower child nutrition risk (mother [Formula: see text] = -3.45, p = 0.02; father [Formula: see text] = -1.74, p = 0.01), as were their healthy home environment scores (mother [Formula: see text] = -8.36, p < 0.001; father [Formula: see text] = -2.69, p = 0.04). Mothers' encouragement of balance and variety was associated with lower nutrition risk ([Formula: see text] = -8.88, p = 0.01), whereas mothers' use of food as a reward was associated with higher nutrition risk ([Formula: see text] = 4.67, p < 0.001). Fathers' modelling of healthy behaviours was associated with lower nutrition risk ([Formula: see text] = -2.21, p = 0.01), whereas fathers' restriction for health ([Formula: see text] = 2.21, p = 0.03) and pressure-to-eat scores ([Formula: see text] = 3.26, p = <0.001) were associated with higher nutrition risk. No associations were found between child nutrition status and parental emotion regulation, control, monitoring, or restriction for weight. In conclusion, both mothers' and fathers' food parenting practices are associated with their children's nutrition status. Fathers should be included in food parenting practices

    Objective Parents may influence children’s fruit and vegetable (F&V) consumption in many ways, but research has focused primarily on counterproductive parenting practices, such as restriction and pressure to eat. The present study aimed to assess the association of diverse parenting practices to promote F&V and its consumption among pre-school children. Design An exploratory analysis was performed on cross-sectional data from 755 Head Start pre-school children and their parents collected in 2004–5. Data included parent practices to facilitate child F&V consumption (grouped into five categories); parent-reported dietary intake of their child over 3 d; and a number of potential correlates. K-means cluster analysis assigned parents to groups with similar use of the food parenting practice categories. Stepwise linear regression analyses investigated the association of parent clusters with children’s consumption of F&V, after controlling for potential confounding factors. Results A three-cluster solution provided the best fit (R2 = 0 62), with substantial differences in the use of parenting practices. The clusters were labelled Indiscriminate Food Parenting, Non-directive Food Parenting and Low-involved Food Parenting. Non-directive parents extensively used enhanced availability and teachable moments’ practices, but less firm discipline practices than the other clusters, and were significantly associated with child F&V intake (standardized β = 0·09, P < 0·1; final model R2 = 0·17) after controlling for confounders, including parental feeding styles. Conclusions Parents use a variety of parenting practices, beyond pressuring to eat and restrictive practices, to promote F&V intake in their young child. Evaluating the use of combinations of practices may provide a better understanding of parental influences on children’s F&V intake. PMID:19490734

    Health-related quality of life (HRQL) is a key indicator of elderly people's health status that can be affected by different factors. However, little is known about which variables are associated with it in functionally independent elderly people. The aim of this project was to study HRQL and a wide variety of health, lifestyle, social and contextual aspects and their relation to HRQL in a sample of functionally independent, non-cognitively impaired community-dwelling adults, over 65 years of age, from a northern region of Spain. A cross-sectional study for which data was collected by face-to-face interviews with the selected individuals. HRQL was measured with the EuroQol-5D scale, consisting of a 5 item descriptive system and a visual analogue scale (VAS). VAS values lower than 70 were considered poor HRQL. Binary logistic regression was used to identify factors related to the outcome. Six hundred and thirty-four individuals were included in the study. The mean age was 74.8 (SD 6.7) years, 55% of the participants were women and 46% rated their HRQL as poor. Several variables were found to be significantly associated with a poor HRQL in the multivariate model, adjusted for age and sex: polypharmacy (OR: 2.32, 95% CI: 1.62-3.31), the presence of sensory impairment (OR: 1.83, 95% CI: 1.24-2.69), not being engaged in cognitively stimulating activities (OR: 2.51, 95% CI: 1.03-6.16), or in group social activities (OR: 1.57, 95% CI: 1.11-2.22), low level of social support (OR: 3.12, 95%CI: 1.78-5.46) and the presence of obstacles in the closest home environment (OR: 1.83, 95%CI: 1.11-3.02). The study identified a set of health, social and contextual variables as strongly related to HRQL in functionally independent community-dwelling older people. The results highlight the multidimensional nature of HRQL. They also reveal the importance of a comprehensive assessment of HRQL when designing adequate health-related programmes aiming to enhance active and healthy ageing and

    Background: No primary practice care model has been shown to be superior in achieving high-quality primary care. We aimed to identify the organizational characteristics of primary care practices that provide high-quality primary care. Methods: We performed a cross-sectional observational study involving a stratified random sample of 37 primary care practices from 3 regions of Quebec. We recruited 1457 patients who had 1 of 2 chronic care conditions or 1 of 6 episodic care conditions. The main outcome was the overall technical quality score. We measured organizational characteristics by use of a validated questionnaire and the Team Climate Inventory. Statistical analyses were based on multilevel regression modelling. Results: The following characteristics were strongly associated with overall technical quality of care score: physician remuneration method (27.0; 95% confidence interval [CI] 19.0–35.0), extent of sharing of administrative resources (7.6; 95% CI 0.8–14.4), presence of allied health professionals (15.3; 95% CI 5.4–25.2) and/or specialist physicians (19.6; 95% CI 8.3–30.9), the presence of mechanisms for maintaining or evaluating competence (7.7; 95% CI 3.0–12.4) and average organizational access to the practice (4.9; 95% CI 2.6–7.2). The number of physicians (1.2; 95% CI 0.6–1.8) and the average Team Climate Inventory score (1.3; 95% CI 0.1–2.5) were modestly associated with high-quality care. Interpretation: We identified a common set of organizational characteristics associated with high-quality primary care. Many of these characteristics are amenable to change through practice-level organizational changes. PMID:23877669

    Fetuin-A is a liver-derived peptide associated with insulin resistance. Aim of this cross-sectional study was to evaluate whether Fetuin-A is increased in patients with nonalcoholic fatty liver disease (NAFLD) vs. healthy subjects without metabolic abnormalities and the association with insulin resistance and liver damage. To investigate the causal relationship between fatty liver and Fetuin-A, we also analysed whether the inherited I148M PNPLA3 variant modulates Fetuin-A. In 137 patients with histological NAFLD, complete metabolic characterization, PNPLA3 genotype, and in 260 healthy subjects without metabolic alterations, Fetuin-A was measured by enzyme-linked immunoabsorbent assay. Serum Fetuin-A was higher in NAFLD patients than in controls (P < 0·0001), independently of age, sex, BMI, insulin resistance, dyslipidemia, adiponectin, PNPLA3 I148M and ALT levels (OR 1·006 95% CI 1·003-1·11; P = 0·003). In NAFLD patients, Fetuin-A was associated with steatosis severity (P = 0·03) and metabolic syndrome features, but not with hepatic inflammation. At multivariate analysis, Fetuin-A levels were associated with BMI, triglycerides, hyperglycemia and PNPLA3 I148M (P = 0·034) independently also of age, sex and ALT levels. As PNPLA3 I148M is a strong and inherited determinant of liver fat without affecting insulin resistance and lipid levels, these data suggest that steatosis has a causal role in determining serum Fetuin-A levels. Liver fat accumulation and the I148M variant of PNPLA3 are associated with serum Fetuin-A levels independently of insulin resistance. Fetuin-A may be implicated in the pathogenesis of metabolic complications associated with NAFLD. © 2014 Stichting European Society for Clinical Investigation Journal Foundation.

    Because exposure to blood by health care workers is frequent during hemodialysis, gloves are required for all contact with patients and their equipment, followed by hand hygiene. In this study, we investigated factors associated with performing these practices as recommended. Staff members from a sample of 45 US hemodialysis facilities were surveyed using an anonymous self-administered questionnaire. Factors independently associated with reporting increased compliance with recommended hand hygiene and glove use practices during patient care were identified with multivariate modeling. Of 605 eligible staff members, 420 (69%) responded: registered nurses, 41%; dialysis technicians, 51%; and licensed practical nurses, 8%. Only 35% reported that dialysis patients were at risk for bloodborne virus infections, and only 36% reported always following recommended hand hygiene and glove use practices. Independent factors associated with more frequent compliance were being a technician (versus a registered nurse) and reporting always doing what was needed to protect themselves from infection. Compliance with recommended hand hygiene and glove use practices by hemodialysis staff was low. The rationale for infection control practices specific to the hemodialysis setting was poorly understood by all staff. Infection control training should be tailored to this setting and should address misconceptions.

  2. Motivated independence? Implicit party identity predicts political judgments among self-proclaimed Independents.

    Reporting an Independent political identity does not guarantee the absence of partisanship. Independents demonstrated considerable variability in relative identification with Republicans versus Democrats as measured by an Implicit Association Test (IAT; M = 0.10, SD = 0.47). To test whether this variation predicted political judgment, participants read a newspaper article describing two competing welfare (Study 1) or special education (Study 2) policies. The authors manipulated which policy was proposed by which party. Among self-proclaimed Independents, those who were implicitly Democratic preferred the liberal welfare plan, and those who were implicitly Republican preferred the conservative welfare plan. Regardless of the policy details, these implicit partisans preferred the policy proposed by "their" party, and this effect occurred more strongly for implicit than explicit plan preference. The authors suggest that implicitly partisan Independents may consciously override some partisan influence when making explicit political judgments, and Independents may identify as such to appear objective even when they are not.

    Objective : The assessment of patients with generalized anxiety disorder (GAD) to deteremine whether a medication intervention is necessary is not always clear and might benefit from a second opinion. However, second opinions are time consuming, expensive, and not practical in most settings. We obtained independent, second opinion reviews of the primary clinician's assessment via audio-digital recording. Design : An audio-digital recording of key site-based assessments was used to generate site-independent "dual" reviews of the clinical presentation, symptom severity, and medication requirements of patients with GAD as part of the screening procedures for a clinical trial (ClinicalTrials.gov: NCT02310568). Results : Site-independent reviewers affirmed the diagnosis, symptom severity metrics, and treatment requirements of 90 moderately ill patients with GAD. The patients endorsed excessive worry that was hard to control and essentially all six of the associated DSM-IV-TR anxiety symptoms. The Hamilton Rating Scale for Anxiety scores revealed moderately severe anxiety with a high Pearson's correlation ( r =0.852) between site-based and independent raters and minimal scoring discordance on each scale item. Based upon their independent reviews, these "second" opinions confirmed that these GAD patients warranted a new medication intervention. Thirty patients (33.3%) reported a previous history of a major depressive episode (MDE) and had significantly more depressive symptoms than patients without a history of MDE. Conclusion : The audio-digital recording method provides a useful second opinion that can affirm the need for a different treatment intervention in these anxious patients. A second live assessment would have required additional clinic time and added patient burden. The audio-digital recording method is less burdensome than live second opinion assessments and might have utility in both research and clinical practice settings.

    The changes in school meal programs stemming from the Healthy, Hunger-Free Kids Act of 2010 have expanded interest in strategies that increase student participation in school lunch and reduce plate waste. However, it remains unclear what factors are associated with schools' use of such strategies. This study examines whether state laws are associated with two types of school meal-related practices: (a) using promotional strategies (ie, taste tests, using posters or announcements) and (b) duration of lunch periods. This cross-sectional study utilized the nationally representative 2014 School Health Policies and Practices Study, combined with corresponding state laws gathered by the National Wellness Policy Study. School data were available from 414 public schools in 43 states. Outcome measures included 16 strategies to promote school meals and the amount of time students had to eat lunch after being seated. Multivariate logistic regression and Poisson regression were used to examine associations between state laws and school practices, after accounting for school demographic characteristics. Compared to schools in states with no law about engaging stakeholders in meal programs, schools in states with a law were more likely to conduct taste tests (64% vs 44%, P=0.016), collect suggestions from students (67% vs 50%, P=0.017), and invite family members to a school meal (71% vs 53%, P=0.015). Schools used more promotion strategies in states with a law than in states without a law (mean=10.4 vs 8.8, P=0.003). Schools were more likely to provide students at least 30 minutes to eat lunch after being seated in states with laws that addressed a minimum amount of time for lunch duration (43% vs 27%, P=0.042). State-level policy provisions are associated with school practices. Policy development in more states may support school practices that promote lunch participation and consumption.

    This article expands on the results from a 1997 report from the Collaborative Study on the Genetics of Alcoholism (COGA), using a new phase of the protocol to evaluate the prevalence and characteristics of substance-induced and independent major depressive episodes (MDEs) in a population of alcoholics and nonalcoholics. Data were evaluated from Phase II of the six-center-wide COGA investigation using information gathered beginning in January 1997. Data were generated through face-to-face evaluations using the updated version of the Semi-Structured Assessment for the Genetics of Alcoholism (SSAGA-II) interview, with distinctions between substanceinduced and independent MDEs based on the chronology of development of full depressive syndromes. The analyses focused on the 2,548 men and women who were divided into 351 individuals who had only an independent MDE (Group 1), 238 subjects who experienced only substance-induced MDEs, and 1,959 individuals with no MDE history. The two MDE groups were similar in age, marital status, and religion; but those with substance-induced depressions (Group 2) were more likely to be original alcoholic probands, be males, be nonwhite, and have less education. They were also more likely to have alcohol, drug, or antisocial personality diagnoses and to report higher maximum drinks. In addition, only Group 2 subjects reported an elevated family history of alcohol diagnoses compared with the nondepressed Group 3. Subjects with independent MDEs were different from the comparison Group 3 regarding the family histories of independent MDEs. However, symptoms during the worst depressive episode were quite similar across Groups 1 and 2. This study corroborates a high rate of substance-induced MDEs among alcoholics, with these disorders explaining about half of the lifetime depressive episodes. The results also support the validity of the distinction between substance-induced and independent depressions regarding external validators of gender

    This paper sought to assess organizational safety practices at three different levels of hierarchical workplace structure and to examine their association with injury outcomes among construction apprentices. Using a cross-sectional sample of 1,775 construction apprentices, three measures of organizational safety practice were assessed: contractor-, steward-, and coworker-safety practice. Each safety practice measure was assessed using three similar questions (i.e., on-the-job safety commitment, following required or recommended safe work practices, and correcting unsafe work practices); the summed average of the responses ranged from 1 to 4, with a higher score indicating poorer safety practice. Outcome variables included the prevalence of four types of musculoskeletal pain (i.e., neck, shoulder, hand, and back pain) and injury-related absence. In adjusted analyses, contractor-safety practice was associated with both hand pain (OR: 1.27, 95 % CI: 1.04, 1.54) and back pain (OR: 1.40, 95 % CI: 1.17, 1.68); coworker-safety practice was related to back pain (OR: 1.42, 95 % CI: 1.18, 1.71) and injury-related absence (OR: 1.36, 95 % CI: 1.11, 1.67). In an analysis that included all three safety practice measures simultaneously, the association between coworker-safety practice and injury-related absence remained significant (OR: 1.68, 95 % CI: 1.20, 2.37), whereas all other associations became non-significant. This study suggests that organizational safety practice, particularly coworker-safety practice, is associated with injury outcomes among construction apprentices.

    Tolerance for ambiguity is essential for optimal learning and professional competence. General practice trainees must be, or must learn to be, adept at managing clinical uncertainty. However, few studies have examined associations of intolerance of uncertainty in this group. The aim of this study was to establish levels of tolerance of uncertainty in Australian general practice trainees and associations of uncertainty with demographic, educational and training practice factors. A cross-sectional analysis was performed on the Registrar Clinical Encounters in Training (ReCEnT) project, an ongoing multi-site cohort study. Scores on three of the four independent subscales of the Physicians' Reaction to Uncertainty (PRU) instrument were analysed as outcome variables in linear regression models with trainee and practice factors as independent variables. A total of 594 trainees contributed data on a total of 1209 occasions. Trainees in earlier training terms had higher scores for 'Anxiety due to uncertainty', 'Concern about bad outcomes' and 'Reluctance to disclose diagnosis/treatment uncertainty to patients'. Beyond this, findings suggest two distinct sets of associations regarding reaction to uncertainty. Firstly, affective aspects of uncertainty (the 'Anxiety' and 'Concern' subscales) were associated with female gender, less experience in hospital prior to commencing general practice training, and graduation overseas. Secondly, a maladaptive response to uncertainty (the 'Reluctance to disclose' subscale) was associated with urban practice, health qualifications prior to studying medicine, practice in an area of higher socio-economic status, and being Australian-trained. This study has established levels of three measures of trainees' responses to uncertainty and associations with these responses. The current findings suggest differing 'phenotypes' of trainees with high 'affective' responses to uncertainty and those reluctant to disclose uncertainty to patients. More

  8. Nurse prescribing in general practice: a qualitative study of job satisfaction and work-related stress.

    Studies examining the impact nurse prescribing have largely focused on the efficacy of the service. It was suggested in pro-prescribing policy arguments that extending the nursing role to include prescribing would increase job satisfaction. This assertion has not been fully explored. To investigate the impact of independent prescribing for experienced nurse practitioners (NPs) working in general practice. In-depth interviews were conducted with six NPs who each had at least 3 years experience of independent prescribing in a busy inner city general practice. Analysis of interview data yielded two main themes: as independent prescribers NPs experienced increased levels of both job satisfaction and work-related stress. Increased satisfaction was associated with having greater autonomy and being able to provide more holistic care. Increased work-related stress emerged from greater job demands, perceived insufficient support and perceived effort-reward imbalance that centred upon the enhanced role not being recognized in terms of an increase in grade and pay. Independent prescribing increases job satisfaction for NPs in general practice, but there is also evidence of stressors associated with the role. It is important that NPs in general practice are encouraged and supported towards providing the effective patient-centred care in the community envisaged by current UK government. We acknowledge that the results presented in this paper are based on a sample limited to one city; however, it provides information that has important implications for the well being of NPs and ultimately patient care.

    Plants harbor a diverse bacterial community, both as epiphytes on the plant surface and as endophytes within plant tissue. While some plant-associated bacteria act as plant pathogens or promote plant growth, others may be human pathogens. The aim of the current study was to determine the bacterial community composition of organic and conventionally grown leafy salad vegetables at the point of consumption using both culture-dependent and culture-independent methods. Total culturable bacteria on salad vegetables ranged from 8.0 × 10(3) to 5.5 × 10(8) CFU g(-1). The number of culturable endophytic bacteria from surface sterilized plants was significantly lower, ranging from 2.2 × 10(3) to 5.8 × 10(5) CFU g(-1). Cultured isolates belonged to six major bacterial phyla, and included representatives of Pseudomonas, Pantoea, Chryseobacterium, and Flavobacterium. Eleven different phyla and subphyla were identified by culture-independent pyrosequencing, with Gammaproteobacteria, Betaproteobacteria, and Bacteroidetes being the most dominant lineages. Other bacterial lineages identified (e.g. Firmicutes, Alphaproteobacteria, Acidobacteria, and Actinobacteria) typically represented less than 1% of sequences obtained. At the genus level, sequences classified as Pseudomonas were identified in all samples and this was often the most prevalent genus. Ralstonia sequences made up a greater portion of the community in surface sterilized than non-surface sterilized samples, indicating that it was largely endophytic, while Acinetobacter sequences appeared to be primarily associated with the leaf surface. Analysis of molecular variance indicated there were no significant differences in bacterial community composition between organic versus conventionally grown, or surface-sterilized versus non-sterilized leaf vegetables. While culture-independent pyrosequencing identified significantly more bacterial taxa, the dominant taxa from pyrosequence data were also detected by traditional

    There has been relatively little empirical evidence about the effects of patient-centered medical home (PCMH) implementation on patient-related outcomes and costs. Using a longitudinal design and a large study group of 2,218 Michigan adult primary care practices, our study examined the following research questions: Is the level of, and change in, implementation of PCMH associated with medical surgical cost, preventive services utilization, and quality of care in the following year? Results indicated that both level and amount of change in practice implementation of PCMH are independently and positively associated with measures of quality of care and use of preventive services, after controlling for a variety of practice, patient cohort, and practice environmental characteristics. Results also indicate that lower overall medical and surgical costs are associated with higher levels of PCMH implementation, although change in PCMH implementation did not achieve statistical significance. © The Author(s) 2015.

    Dietary fatty acids are known to affect serum lipoproteins; however, little is known about the associations between consumption of dietary fatty acids and lipoprotein subclasses. In this study, we hypothesized that there is an association between dietary fatty acids and lipoprotein subclasses and investigated the cross-sectional association of dietary fat intake with subclasses of lipoproteins in elderly women. Altogether, 547 women (aged ≥65 years) who were part of OSTPRE cohort participated. Dietary intake was assessed by 3-day food records, lifestyle, and health information obtained through self-administrated questionnaires, and lipoprotein subclasses were determined by nuclear magnetic resonance spectroscopy. To analyze the associations between fatty acids and lipoprotein subclasses, we used Pearson and Spearman correlation coefficients and the analysis of covariance (ANCOVA) test with, adjustment for physical activity, body mass index, age, smoking status, and intake of lipid-lowering drugs. There were significant correlations between saturated fatty acids (SFA; % of energy) and concentrations of large, medium, and small low-density lipoproteins (LDL); total cholesterol in large, medium, and small LDL; and phospholipids in large, medium, and small LDL, after correction for multiple testing. After adjustment for covariates, the higher intake of SFA was associated with smaller size of LDL particles (P = .04, ANCOVA) and lower amount of triglycerides in small very low-density lipoproteins (P = .046, ANCOVA). However, these associations did not remain significant after correction for multiple testing. In conclusion, high intake of SFA may be associated with the size of LDL particles, but the results do not support significant, independent associations between dietary fatty acids and lipoprotein subclasses.

    The increased popularity of mind-body practices highlights the need to explore their potential effects. We determined the cross-sectional association between mind-body practices and cardiometabolic risk factors. We used data from 2579 participants free of cardiovascular disease from the Rotterdam Study (2009-2013). A structured home-based interview was used to evaluate engagement in mind-body practices including meditation, yoga, self-prayer, breathing exercises, or other forms of mind-body practice. We regressed engagement in mind-body practices on cardiometabolic risk factors (body mass index, blood pressure, and fasting blood levels of cholesterol, triglycerides, and glucose) and presence of metabolic syndrome. All analyses were adjusted for age, sex, educational level, smoking, alcohol consumption, (in)activities in daily living, grief, and depressive symptoms. Fifteen percent of the participants engaged in a form of mind-body practice. Those who did mind-body practices had significantly lower body mass index (β = -0.84 kg/m, 95% confidence interval [CI] = -1.30 to -0.38, p < .001), log-transformed triglyceride levels (β = -0.02, 95% CI = -0.04 to -0.001, p = .037), and log-transformed fasting glucose levels (β = -0.01, 95% CI = -0.02 to -0.004, p = .004). Metabolic syndrome was less common among individuals who engaged in mind-body practices (odds ratio = 0.71, 95% CI = 0.54-0.95, p = .019). Individuals who do mind-body practices have a favorable cardiometabolic risk profile compared with those who do not. However, the cross-sectional design of this study does not allow for causal inference and prospective, and intervention studies are needed to elucidate the association between mind-body practices and cardiometabolic processes.

    Measurement-device-independent quantum key distribution (MDI-QKD) with the active decoy state method can remove all detector loopholes, and resist the imperfections of sources. But it may lead to side channel attacks and break the security of QKD system. In this paper, we apply the passive decoy state method to the MDI-QKD based on polarization encoding mode. Not only all attacks on detectors can be removed, but also the side channel attacks on sources can be overcome. We get that the MDI-QKD with our passive decoy state method can have a performance comparable to the protocol with the active decoy state method. To fit for the demand of practical application, we discuss intensity fluctuation in the security analysis of MDI-QKD protocol using passive decoy state method, and derive the key generation rate for our protocol with intensity fluctuation. It shows that intensity fluctuation has an adverse effect on the key generation rate which is non-negligible, especially in the case of small data size of total transmitting signals and long distance transmission. We give specific simulations on the relationship between intensity fluctuation and the key generation rate. Furthermore, the statistical fluctuation due to the finite length of data is also taken into account.

    Celiac disease is a common autoimmune disease caused by sensitivity to the dietary protein gluten. Forty loci have been implicated in the disease. All disease loci have been characterized as low-penetrance, with the exception of the high-risk genotypes in the HLA-DQA1 and HLA-DQB1 genes, which are necessary but not sufficient to cause the disease. The very strong effects from the known HLA loci and the genetically complex nature of the major histocompatibility complex (MHC) have precluded a thorough investigation of the region. The purpose of this study was to test the hypothesis that additional celiac disease loci exist within the extended MHC (xMHC). A set of 1898 SNPs was analyzed for association across the 7.6 Mb xMHC region in 1668 confirmed celiac disease cases and 517 unaffected controls. Conditional recursive partitioning was used to create an informative indicator of the known HLA-DQA1 and HLA-DQB1 high-risk genotypes that was included in the association analysis to account for their effects. A linkage disequilibrium-based grouping procedure was utilized to estimate the number of independent celiac disease loci present in the xMHC after accounting for the known effects. There was significant statistical evidence for four new independent celiac disease loci within the classic MHC region. This study is the first comprehensive association analysis of the xMHC in celiac disease that specifically accounts for the known HLA disease genotypes and the genetic complexity of the region.

    Many previous studies have shown that meditation practice has a positive impact on cognitive and non-cognitive functioning, which are related to job performance. Thus, the aims of this study were to (1) estimate the prevalence of meditation practice, (2) identify the characteristics of individuals who practice meditation, and (3) examine the association between meditation practice and job performance. Two population-based, cross-sectional surveys were conducted. In study 1, we examined the prevalence of meditation practice and the characteristics of the persons practicing meditation; in Study 2, we examined the association between meditation practice and job performance. The outcome variables included work engagement, subjective job performance, and job satisfaction. The Utrecht Work Engagement Scale was used to assess work engagement, the World Health Organization Health and Work Performance Questionnaire (HPQ) was used to measure subjective job performance, and a scale developed by the Japanese government was used to assess job satisfaction. Hierarchical multiple regression analyses were used in Study 2. Demographic characteristics and behavioral risk factors were included as covariates in the analyses. The results of Study 1 indicated that 3.9% of persons surveyed (n = 30,665) practiced meditation; these individuals were younger and had a higher education, higher household income, higher stress level, and lower body mass index than those who did not practice meditation. The results of Study 2 (n = 1,470) indicated that meditation practice was significantly predictive of work engagement (β = 0.112, p < .001), subjective job performance (β = 0.116, p < .001), and job satisfaction (β = 0.079, p = .002), even after adjusting for covariates (β = 0.083, p < .001; β = 0.104, p < .001; β = 0.060, p = .015, respectively).

    The prevalence of obesity is greater among adults living in rural compared to urban areas of the USA. Greater obesity risk among rural adults persists after adjusting for obesity-related behaviors and sociodemographic factors. With the rural-urban obesity disparity greatest among younger adults, it is important to examine the complexity of factors that may increase the risk for excess body weight in this population so that effective preventive interventions can be implemented. College students residing in economically deprived rural areas such as rural Appalachia may be particularly at risk for excess body weight from exposure to both rural and college obesogenic environments. The purpose of this study was to determine if living in economically distressed rural Appalachia is independently associated with excess body weight among college students. College students aged 18-25 years who were lifetime residents of either rural Eastern Appalachian Kentucky (n=55) or urban Central Kentucky (n=54) participated in this cross-sectional study. Students completed questionnaires on sociodemographics, depressive symptoms, and health behaviors including smoking, fruit and vegetable intake, and physical activity. Height and weight were obtained during a brief health examination to calculate body-mass index (BMI). Excess body weight was defined as being overweight or obese with a BMI of 25 kg/m2 or greater. Binary logistic regression was used to determine if living in economically distressed rural Appalachia was independently associated with excess body weight. The prevalence of excess body weight was higher in the rural Appalachian group than the urban group (50% vs 24%, p0.001). Depressive symptom scores and smoking prevalence were also greater in the rural Appalachian group. There were no differences in fruit and vegetable intake and vigorous physical activity between the groups. Residing in economically distressed rural Appalachia was associated with more

    The literature of action control claims that humans control their actions in two ways. In the stimulus-based approach, actions are triggered by external stimuli. In the ideomotor approach, actions are elicited endogenously and controlled by the intended goal. In the current study, our purpose was to investigate whether these two action control modes affect task-switching differently. We combined a classical task-switching paradigm with action-effect learning. Both experiments consisted of two experimental phases: an acquisition phase, in which associations between task, response and subsequent action effects were learned and a test phase, in which the effects of these associations were tested on task performance by presenting the former action effects as preceding effects, prior to the task (called practiced effects ). Subjects either chose freely between tasks (ideomotor action control mode) or they were cued as to which task to perform (sensorimotor action control mode). We aimed to replicate the consistency effect (i.e., task is chosen according to the practiced task-effect association) and non-reversal advantage (i.e., better task performance when the practiced effect matches the previously learned task-effect association). Our results suggest that participants acquired stable action-effect associations independently of the learning mode. The consistency effect (Experiment 1) could be shown, independent of the learning mode, but only on the response-level. The non-reversal advantage (Experiment 2) was only evident in the error rates and only for participants who had practiced in the ideomotor action control mode.

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

    Objectives This paper sought to assess organizational safety practices at three different levels of hierarchical workplace structure and to examine their association with injury outcomes among construction apprentices. Methods Using a cross-sectional sample of 1,775 construction apprentices, three measures of organizational safety practice were assessed: contractor-, steward-, and coworker-safety practice. Each safety practice measure was assessed using three similar questions (i.e., on-the-job safety commitment, following required or recommended safe work practices, and correcting unsafe work practices); the summed average of the responses ranged from 1 to 4, with a higher score indicating poorer safety practice. Outcome variables included the prevalence of four types of musculoskeletal pain (i.e., neck, shoulder, hand, and back pain) and injury-related absence. Results In adjusted analyses, contractor-safety practice was associated with both hand pain (OR: 1.27, 95 % CI: 1.04, 1.54) and back pain (OR: 1.40, 95 % CI: 1.17, 1.68); coworker-safety practice was related to back pain (OR: 1.42, 95 % CI: 1.18, 1.71) and injury-related absence (OR: 1.36, 95 % CI: 1.11, 1.67). In an analysis that included all three safety practice measures simultaneously, the association between coworker-safety practice and injury-related absence remained significant (OR: 1.68, 95 % CI: 1.20, 2.37), whereas all other associations became non-significant. Conclusions This study suggests that organizational safety practice, particularly coworker-safety practice, is associated with injury outcomes among construction apprentices. PMID:23748366

    Nurses utilize transcultural, transactional, systems, primary, and interdisciplinary approaches to physiological and psychosocial components of patient care. Expanded roles, as well as advances in knowledge and technology have prepared nurses for critical, specialized, primary, aerospace, and independent nursing practice. Exciting as they are, nursing's expanded roles and practices frequently contribute to the burnout and distress phenomena increasingly observed in practicing health care professionals. Causes and symptoms of the burnout distress phenomena are many and varied. Selye, Shubin, Maslach, and others adeptly identified and wrote on the phenomena as it specifically relates to nurses and the many facets of nursing practice. Rather than utilizing crisis intervention coping techniques, preventive strategies and adaptations are suggested. This paper reviews and discusses: 1. Factors associated with burnout-distress phenomena identified in professional literature; 2. Identification of factors associated with expanded roles and practice which contribute to burnout stress; 3. Identification of factors in military and civilian air ambulance and aeromedical evacuation systems which contribute to burnout stress; 4. Recommendations for strategies to prevent and cope with burnout distress factors.

    The purpose of this study was to understand how the term independence is used in rehabilitation. In particular, we asked occupational therapists in Canada and Japan to interpret the term independence in terms of people with disabilities. In rehabilitation, independence has long been a key concept. A review of the literature shows that the term's meaning has shifted throughout the past century. However, despite its significance, the word's meaning has never been deeply analysed, and it is left to the interpretation of the individual practitioner; consequently, there is a conceptual confusion surrounding the term. Furthermore, no studies have been conducted from an inter-cultural viewpoint that included non-Western societies. A qualitative interpretive study was conducted, based on semi-structured interviews with 18 occupational therapists. Nine Canadian and nine Japanese therapists were interviewed in depth and their perspectives analysed for themes and categories corresponding to their working definition of independence. Therapists' interpretation of the term independence consisted of three perspectives: "Independence as competence,"Independence as autonomy," and "Independence as psychological qualities". These perspectives were typically combined into two patterns of dealing with independence in practice. Differences between Canadian and Japanese perspectives were explored. The study's findings confirm some ideas about independence that have been pointed out in the professional literature, but they also add several important ideas - the idea of psychological characteristics as key to independence, and the notion of a cultural overlay on the definition and application of the concept independence. This study's findings should contribute to the ongoing discussion in the professional literature about the virtues and limitations of pursuing independence as the ultimate goal in rehabilitation.

    Clinical pharmacist practice is well established in the safe and effective use of medicines in the critically ill patient. In the UK, independent pharmacist prescribers are generally recognised as a valuable and desirable resource. However, currently, there are only anecdotal reports of pharmacist-independent prescribing in critical care. The aim of this questionnaire was to determine the current and proposed future independent prescribing practice of UK clinical pharmacists working in adult critical care. The questionnaire was distributed electronically to UK Clinical Pharmacy Association members (closed August 2014). There were 134 responses to the questionnaire (response rate at least 33%). Over a third of critical care pharmacists were practising independent prescribers in the specialty, and 70% intended to be prescribers within the next 3 years. Pharmacists with ≥5 years critical care experience (P < 0.001) or worked in a team (P = 0.005) were more likely to be practising independent prescribers. Pharmacists reported significant positives to the use of independent prescribing in critical care both in patient care and job satisfaction. Independently, prescribing was routine in: dose adjustment for multi-organ failure, change in route or formulation, correction prescribing errors, therapeutic drug monitoring and chronic medication. The majority of pharmacist prescribers reported they spent ≤5% of their clinical time prescribing and accounted for ≤5% of new prescriptions in critical care patients. Most critical care pharmacists intend to be practising as independent prescribers within the next 3 years. The extent and scope of critical care pharmacist prescribing appear to be of relatively low volume and within niche prescribing areas. © 2015 Royal Pharmaceutical Society.

    Mexican Americans are at an increased risk of both thyroid dysfunction and metabolic syndrome (MS). Thus it is conceivable that some components of the MS may be associated with the risk of thyroid dysfunction in these individuals. Our objective was to investigate and replicate the potential association of MS traits with thyroid dysfunction in Mexican Americans. We conducted association testing for 18 MS traits in two large studies on Mexican Americans - the San Antonio Family Heart Study (SAFHS) and the National Health and Nutrition Examination Survey (NHANES) 2007-10. A total of 907 participants from 42 families in SAFHS and 1633 unrelated participants from NHANES 2007-10 were included in this study. The outcome measures were prevalence of clinical and subclinical hypothyroidism and thyroid function index (TFI) - a measure of thyroid function. For the SAFHS, we used polygenic regression analyses with multiple covariates to test associations in setting of family studies. For the NHANES 2007-10, we corrected for the survey design variables as needed for association analyses in survey data. In both datasets, we corrected for age, sex and their linear and quadratic interactions. TFI was an accurate indicator of clinical thyroid status (area under the receiver-operating-characteristic curve to detect clinical hypothyroidism, 0.98) in both SAFHS and NHANES 2007-10. Of the 18 MS traits, waist circumference (WC) showed the most consistent association with TFI in both studies independently of age, sex and body mass index (BMI). In the SAFHS and NHANES 2007-10 datasets, each standard deviation increase in WC was associated with 0.13 (p < 0.001) and 0.11 (p < 0.001) unit increase in the TFI, respectively. In a series of polygenic and linear regression models, central obesity (defined as WC ≥ 102 cm in men and ≥88 cm in women) was associated with clinical and subclinical hypothyroidism independent of age, sex, BMI and type 2 diabetes in both datasets

    Despite the solid connection between REV-ERB and obesity, the information about whether genetic variations at this locus may be associated with obesity traits is scarce. Therefore our objective was to study the association between REV-ERB-ALPHA1 rs2314339 and obesity in two independent populations. Participants were 2214 subjects from Spanish Mediterranean (n = 1404) and North American (n = 810) populations. Anthropometric, biochemical, dietary, and genotype analyses were performed. We found novel associations between the REV-ERB-ALPHA1 rs2314339 genotype and obesity in two independent populations: in Spanish Mediterranean and North American groups, the frequency of the minor-allele-carriers (AA+ AG) was significantly lower in the "abdominally obese" group than in those of the "nonabdominally obese" group (p < 0.05). Minor allele carriers had lower probability of abdominal obesity than noncarriers, and the effect was of similar magnitude for both populations (OR ≈ 1.50). There were consistent associations between REV-ERB-ALPHA1 genotype and obesity-related traits (p < 0.05). Energy intake was not significantly associated with REV-ERB-ALPHA1 rs2314339. However, physical activity significantly differed by genotype. A significant interaction between the REV-ERB-ALPHA1 variant and monounsaturated-fatty-acids (MUFA) intake for obesity was also detected in the Mediterranean population. This new discovery highlights the importance of REV-ERB-ALPHA1 in obesity and provides evidence for the connection between our biological clock and obesity-related traits. © 2013 WILEY-VCH Verlag GmbH & Co.

    Background The association between sarcopenia and cardiovascular disease (CVD) in elderly people has not been adequately assessed. The aim of this study was to investigate whether CVD is more prevalent in subjects with sarcopenia independent of other well-established cardiovascular risk factors in older Korean adults. Method This study utilized the representative Korean population data from the Korea National Health and Nutrition Examination Survey (KNHANES) which was conducted in 2009. Subjects older than 65 years of age with appendicular skeletal muscle mass (ASM) determined by dual energy X-ray absorptiometry were selected. The prevalence of sarcopenia in the older Korean adults was investigated, and it was determined whether sarcopenia is associated with CVD independent of other well-known risk factors. Results 1,578 subjects aged 65 years and older with the data for ASM were selected, and the overall prevalence of sarcopenia was 30.3% in men and 29.3% in women. Most of the risk factors for CVD such as age, waist circumference, body mass index, fasting plasma glucose and total cholesterol showed significant negative correlations with the ratio between appendicular skeletal muscle mass and body weight. Multiple logistic regression analysis demonstrated that sarcopenia was associated with CVD independent of other well-documented risk factors, renal function and medications (OR, 1.768; 95% CI, 1.075–2.909, P = 0.025). Conclusions Sarcopenia was associated with the presence of CVD independent of other cardiovascular risk factors after adjusting renal function and medications. PMID:23533671

    Conflicting data exist on the impact of dietary and circulating levels of branched chain amino acids (BCAA) on cardiometabolic health and it is unclear to what extent these relations are mediated by genetics. In a cross-sectional study of 1997 female twins we examined associations between BCAA intake, measured using food frequency-questionnaires, and a range of markers of cardiometabolic health, including DXA-measured body fat, blood pressure, HOMA-IR, high-sensitivity C-reactive protein (hs-CRP) and lipids. We also measured plasma concentrations of BCAA and known metabolites of amino acid metabolism using untargeted mass spectrometry. Using a within-twin design, multivariable analyses were used to compare the associations between BCAA intake and endpoints of cardiometabolic health, independently of genetic confounding. Higher BCAA intake was significantly associated with lower HOMA-IR (-0.1, P-trend 0.02), insulin (-0.5μU/mL, P-trend 0.03), hs-CRP -0.3mg/L, P-trend 0.01), systolic blood pressure (-2.3mmHg, P-trend 0.01) and waist-to-height ratio (-0.01, P-trend 0.04), comparing extreme quintiles of intake. These associations persisted in within-pair analysis for monozygotic twins for insulin resistance (P<0.01), inflammation (P=0.03), and blood pressure (P=0.04) suggesting independence from genetic confounding. There was no association between BCAA intake and plasma concentrations, although two metabolites previously associated with obesity were inversely associated with BCAA intake (alpha-hydroxyisovalerate and trans-4-hydroxyproline). Higher intakes of BCAA were associated, independently of genetics, with lower insulin resistance, inflammation, blood pressure and adiposity-related metabolites. The BCAA intake associated with our findings is easily achievable in the habitual diet. Copyright © 2016 The Authors. Published by Elsevier Ireland Ltd.. All rights reserved.

    to investigate associations between different types of child disciplinary practices and children and adolescents' bullying behavior in a Brazilian sample. cross-sectional study, with a school-based sample of 10- to 15-year-old children and adolescents. Child disciplinary practices were assessed using two main subtypes: power-assertive and punitive (psychological aggression, corporal punishment, deprivation of privileges, and penalty tasks) and inductive (explaining, rewarding, and monitoring). A modified version of the Olweus Bully Victim Questionnaire was used to measure the frequency of bullying. 247 children and adolescents were evaluated and 98 (39.7%) were classified as bullies. Power-assertive and punitive discipline by either mother or father was associated with bullying perpetration by their children. Mothers who mostly used this type of discipline were 4.36 (95% CI: 1.87-10.16; p<0.001) times more likely of having a bully child. Psychological aggression and mild forms of corporal punishment presented the highest odds ratios. Overall inductive discipline was not associated with bullying. bullying was associated to parents' assertive and punitive discipline. Finding different ways of disciplining children and adolescents might decrease bullying behavior. Copyright © 2014 Sociedade Brasileira de Pediatria. Published by Elsevier Editora Ltda.

    To examine prehospital emergency medical services (EMS) scope of practice for acute cardiovascular events and characteristics that may affect scope of practice; and to describe variations in EMS scope of practice for these events and the characteristics associated with that variability. In 2008, we conducted a telephone survey of 1,939 eligible EMS providers in nine states to measure EMS agency characteristics, medical director involvement, and 18 interventions authorized for prehospital care of acute cardiovascular events by three levels of emergency medical technician (EMT) personnel. A total of 1,292 providers responded to the survey, for a response rate of 67%. EMS scope of practice interventions varied by EMT personnel level, with the proportion of authorized interventions increasing as expected from EMT-Basic to EMT-Paramedic. Seven of eight statistically significant associations indicated that EMS agencies in urban settings were less likely to authorize interventions (odds ratios <0.7) for any level of EMS personnel. Based on the subset of six statistically significant associations, fire department-based EMS agencies were two to three times more likely to authorize interventions for EMT-Intermediate personnel. Volunteer EMS agencies were more than twice as likely as nonvolunteer agencies to authorize interventions for EMT-Basic and EMT-Intermediate personnel but were less likely to authorize any one of the 11 interventions for EMT-Paramedics. Greater medical director involvement was associated with greater likelihood of authorization of seven of the 18 interventions for EMT-Basic and EMT-Paramedic personnel but had no association with EMT-Intermediate personnel. We noted statistically significant variations in scope of practice by rural vs. urban setting, medical director involvement, and type of EMS service (fire department-based/non-fire department-based; volunteer/paid). These variations highlight local differences in the composition and capacity of EMS

    Self-medication with antibiotics (SMA) is a serious global health problem. We sought to investigate SMA behaviors and risk factors among Chinese university students, and further explore the association between SMA practices and adverse drug events (ADEs). Cross-sectional study. An online survey was conducted at Jiangsu University (JSU) in eastern China in July 2011 using a pretested questionnaire. Out of 2608 website visitors, 1086 participated in the survey (response rate: 41.6%), 426 respondents were excluded for not being a JSU student or repeat participation, 660 (2.2% of JSU students) were included in analysis, and 316 students (47.9%) had a lifetime history of SMA. Among self-treated students, 43.5% believed that antibiotic was suitable for viral infections, 65.9% had more than one SMA episode in the previous year, 73.5% self-medicated with at least two different antibiotics, 57.1% and 64.4% changed antibiotic dosage and antibiotics during the course, respectively. Female gender, older age, and prior knowledge of antibiotics (PKA) were identified as independent risk factors of SMA. There was no difference between students with and without PKA regarding SMA frequency, use of polyantibiotics, and switching antibiotic dosage or antibiotics. ADEs happened to 13.3% of self-medicated students. Frequent change of dosage and simultaneous use of the same antibiotic with different names were independent risk practices associated with an ADE. Our findings substantiate high SMA prevalence among Chinese university students. Older age and PKA are independent SMA risk factors common to Chinese university students and female gender is exclusive SMA risk factor for JSU students. Poor SMA practices are associated with ADEs. Strict regulations on antibiotic sales and public education reinforced by further health care reform are recommended. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

    This Point/Counterpoint article discusses the transformation of dental practice from the traditional solo/small-group (partnership) model of the 1900s to large Dental Support Organizations (DSO) that support affiliated dental practices by providing nonclinical functions such as, but not limited to, accounting, human resources, marketing, and legal and practice management. Many feel that DSO-managed group practices (DMGPs) with employed providers will become the setting in which the majority of oral health care will be delivered in the future. Viewpoint 1 asserts that the traditional dental practice patterns of the past are shifting as many younger dentists gravitate toward employed positions in large group practices or the public sector. Although educational debt is relevant in predicting graduates' practice choices, other variables such as gender, race, and work-life balance play critical roles as well. Societal characteristics demonstrated by aging Gen Xers and those in the Millennial generation blend seamlessly with the opportunities DMGPs offer their employees. Viewpoint 2 contends the traditional model of dental care delivery-allowing entrepreneurial practitioners to make decisions in an autonomous setting-is changing but not to the degree nor as rapidly as Viewpoint 1 professes. Millennials entering the dental profession, with characteristics universally attributed to their generation, see value in the independence and flexibility that a traditional practice allows. Although DMGPs provide dentists one option for practice, several alternative delivery models offer current dentists and future dental school graduates many of the advantages of DMGPs while allowing them to maintain the independence and freedom a traditional practice provides.

    Yoga is promoted or weight maintenance, but there is little evidence of its efficacy. To examine whether yoga practice is associated with lower mean 10-year weight gain after age 45. Participants included 15,550 adults, aged 53 to 57 years, recruited to the Vitamin and Lifestyle (VITAL) cohort study between 2000 and 2002. Physical activity (including yoga) during the past 10 years, diet, height, and weight at recruitment and at ages 30 and 45. All measures were based on self-reporting, and past weight was retrospectively ascertained. Multiple regression analyses were used to examined covariate-adjusted associations between yoga practice and weight change from age 45 to recruitment, and polychotomous logistic regression was used to examine associations of yoga practice with the relative odds of weight maintenance (within 5%) and weight loss (> 5%) compared to weight gain. Yoga practice for four or more years was associated with a 3.1-lb lower weight gain among normal weight (BMI < 25) participants [9.5 lbs versus 12.6 Ibs] and an 18.5-lb lower weight gain among overweight participants [-5.0 lbs versus 13.5 Ibs] (both P for trend <.001). Among overweight individuals, 4+ years of yoga practice was associated with a relative odds of 1.85 (95% confidence interval [CI] 0.63-5.42) for weight maintenance (within 5%) and 3.88 (95% Cl 1.30-9.88) for weight loss (> 5%) compared to weight gain (P for trend .026 and .003, respectively). Regular yoga practice was associated with attenuated weight gain, most strongly among individuals who were overweight. Although causal inference from this observational study is not possible, results are consistent with the hypothesis that regular yoga practice can benefit individuals who wish to maintain or lose weight.

    Background Stroke survivors have a high incidence of falls. Impaired executive-controlled processes are frequent in stroke survivors and are associated with falls in this population. Better understanding of the independent association between executive-controlled processes and physiological fall risk (i.e. performances of balance and mobility) could enhance future interventions that aim to prevent falls and to promote an independent lifestyle among stroke survivors. Methods Cross-sectional analysis of 63 adults who suffered a mild stroke >1 year prior to the study, aged > or =50 years. Results Cognitive flexibility was independently associated with performances of balance and mobility in community-dwelling older adults after mild stroke, after accounting for age, quadriceps strength of the paretic side and current physical activity level. Conclusions Clinicians may need to consider cognitive function when assessing and treating impaired balance and mobility in community-dwelling older adults after mild stroke. PMID:17143004

    Endocan is a new marker of endothelial cell activation that mediates adhesion of leukocytes into endothelium. Soluble intercellular (sICAM-1) and vascular cellular (sVCAM-1) adhesion molecules play an important role in the prevalence of cardiovascular disease (CVD) in chronic kidney disease (CKD) patients. The aim of this study is to investigate whether endocan could affect the concentrations of sICAM-1 and sVCAM-1 in CKD patients, particularly in those with CVD. We evaluated plasma endocan, sICAM-1, sVCAM-1 and the markers of inflammation: high sensitivity C-reactive protein (hs CRP), interleukin-6, tumor necrosis factor-α (TNF-α) and their interrelationships in 53 CKD patients (both with and without CVD) and 29 healthy controls. Endocan, sICAM-1, sVCAM-1 and inflammatory markers were significantly higher in CKD patients than in controls, and patients with CVD had levels significantly higher (except interleukin-6 and TNF-α) than those without CVD. The presence of CVD, ferritin, TNF-α and SBP were the independent predictors of endocan levels in the whole CKD group. In this group, the weak relationship was between endocan and sICAM-1 and sVCAM-1, but age was the only independent predictor of these adhesion molecules. The strong association between endocan and sICAM-1 and sVCAM-1 was exclusively observed in subgroup with CVD, and the low % of lymphocytes followed by increased endocan was identified as the independent variables significantly associated with these soluble molecule levels. This study shows that plasma endocan is significantly increased and independently associated with sICAM-1 and sVCAM-1 levels in CKD patients with cardiovascular complications.

    Composed of ultrathin metal or dielectric nanostructures, metasurfaces can manipulate the phase, amplitude and polarization of electromagnetic waves at a subwavelength scale, which is promising for flat optical devices. In general, metasurfaces composed of space-variant anisotropic units are sensitive to the incident polarization due to the inherent polarization dependent geometric phase. Here, we implement polarization-independent broadband metasurface holograms constructed by polarization-dependent anisotropic elliptical nanoholes by elaborate design of complex amplitude holograms. The fabricated meta-hologram exhibits a polarization insensitive feature with an acceptable image quality. We verify the feasibility of the design algorithm for three-dimensional (3D) meta-holograms with simulation and the feasibility for two-dimensional (2D) meta-holograms is experimentally demonstrated at a broadband wavelength range from 405 nm to 632.8 nm. The effective polarization-independent broadband complex wavefront control with anisotropic elliptical nanoholes proposed in this paper greatly promotes the practical applications of the metasurface in technologies associated with wavefront manipulation, such as flat lens, colorful holographic displays and optical storage.

    In this study, whether physical activity is independently associated with direct healthcare costs in community-dwelling older adults with multiple chronic conditions was examined. Cross-sectional analysis. Research laboratory. 299 community-dwelling men and women volunteers aged 65 years and older with chronic conditions. None. Primary dependent variable was direct healthcare costs incurred in the previous 3 months. Participants completed the Health Resource Utilisation (HRU) questionnaire. To estimate HRU, direct costs in the previous 3 months were calculated using the three-party payer perspective of the British Columbia Ministry of Health, deemed representative of the Canadian healthcare system costs. For medications, the Retail Pharmacy Dispensed prescription cost tables were used. Primary independent variables were (1) self-report current level of physical activity as assessed by the Physical Activity Scale for Individuals with Physical Disabilities (PASIPD) and (2) general balance and mobility as assessed by the National Institute on Aging Balance Scale. The mean number of chronic conditions per participant was six. Current level of physical activity was independently and inversely associated with HRU. Age, sex, number of chronic conditions, global cognitive function, body mass index, and general balance and mobility together accounted for 24.3% of the total variance. Adding the PASIPD score resulted in an R2 change of 3.3% and significantly improved the model. The total variance accounted by the final model was 27.6%. Physical activity promotion may reduce healthcare costs in older adults with chronic conditions.

    Using baseline data from a randomized controlled pediatric obesity prevention trial, this study sought to examine general parenting style as a potential moderator of the association between feeding-specific parenting practices and child dietary intake. Four hundred and twenty-one parent-child dyads served as participants (49% girls and 93% mothers). Children were, on average, 6.6 years old and either overweight or at-risk for overweight (mean BMI percentile = 84.9). Data were collected in participants’ homes. Study staff measured children’s height and weight. Parents completed questionnaires designed to assess general parenting styles (authoritative, authoritarian and permissive) and child feeding practices (restriction and monitoring). Child dietary intake was assessed using a 24-hour recall system. Outcomes were daily servings of fruits and vegetables, sugar-sweetened beverages (SSB), and unhealthy snacks. Results were as follows: Permissive parenting was inversely associated with fruit and vegetable consumption, and parental monitoring was inversely associated with SSB consumption. There were no other main effects of parenting style or feeding practice on child dietary consumption. Authoritarian parenting moderated the association between restriction and SSB intake (a marginally significant effect after correcting for multiple comparisons). Restriction was inversely associated with SSB consumption when authoritarianism was high but unassociated with SSB consumption when authoritarianism was low. Findings indicate that the parenting practice of monitoring child dietary intake was associated with more healthful consumption regardless of parenting style; interventions may thus benefit from encouraging parental monitoring. The parenting strategy of restricting child dietary intake, in contrast, was associated with lower SSB intake in the context of higher parental authoritarianism but inconsequential in the context of lower parental authoritarianism.

    Background Symbioses between metazoans and microbes are widespread and vital to many ecosystems. Recent work with several nematode species has suggested that strong associations with microbial symbionts may also be common among members of this phylu. In this work we explore possible symbiosis between bacteria and the free living soil bacteriovorous nematode Acrobeloides maximus. Methodology We used a soil microcosm approach to expose A. maximus populations grown monoxenically on RFP labeled Escherichia coli in a soil slurry. Worms were recovered by density gradient separation and examined using both culture-independent and isolation methods. A 16S rRNA gene survey of the worm-associated bacteria was compared to the soil and to a similar analysis using Caenorhabditis elegans N2. Recovered A. maximus populations were maintained on cholesterol agar and sampled to examine the population dynamics of the microbiome. Results A consistent core microbiome was extracted from A. maximus that differed from those in the bulk soil or the C. elegans associated set. Three genera, Ochrobactrum, Pedobacter, and Chitinophaga, were identified at high levels only in the A. maximus populations, which were less diverse than the assemblage associated with C. elegans. Putative symbiont populations were maintained for at least 4 months post inoculation, although the levels decreased as the culture aged. Fluorescence in situ hybridization (FISH) using probes specific for Ochrobactrum and Pedobacter stained bacterial cells in formaldehyde fixed nematode guts. Conclusions Three microorganisms were repeatedly observed in association with Acrobeloides maximus when recovered from soil microcosms. We isolated several Ochrobactrum sp. and Pedobacter sp., and demonstrated that they inhabit the nematode gut by FISH. Although their role in A. maximus is not resolved, we propose possible mutualistic roles for these bacteria in protection of the host against pathogens and facilitating enzymatic

    Introduction Immune response variations after vaccination are influenced by host genetic factors and demographic variables, such as race, ethnicity and sex. The latter have not been systematically studied in regard to live rubella vaccine, but are of interest for developing next generation vaccines for diverse populations, for predicting immune responses after vaccination, and for better understanding the variables that impact immune response. Methods We assessed associations between demographic variables, including race, ethnicity and sex, and rubella-specific neutralizing antibody levels and secreted cytokines (IFN! , IL-6) in two independent cohorts (1,994 subjects), using linear and linear mixed models approaches, and genetically defined racial and ethnic categorizations. Results Our replicated findings in two independent, large, racially diverse cohorts indicate that individuals of African descent have significantly higher rubella-specific neutralizing antibody levels compared to individuals of European descent and/or Hispanic ethnicity (p! 0.001). Conclusion Our study provides consistent evidence for racial/ethnic differences in humoral immune response following rubella vaccination. PMID:24530932

    An independent distance scale for Cepheid variables is discussed. The apparent magnitude and the visual surface brightness, inferred from an appropriate color index, are used to determine the angular diameter variation of the Cepheid. When combined with the linear displacement curve obtained from the integrated radial velocity curve, the distance and linear radius are determined. The attractiveness of the method is its complete independence of all other stellar distance scales, even though a number of practical difficulties currently exist in implementing the technique.

    Introduction People living with HIV (PLWH) need to adhere to antiretroviral therapy (ART) to achieve optimal health. One reason for ART non-adherence is HIV-related stigma. Objectives We aimed to examine whether HIV treatment self-efficacy (an intrapersonal mechanism) mediates the stigma – adherence association. We also examined whether self-efficacy and the concern about being seen while taking HIV medication (an interpersonal mechanism) are parallel mediators independent of each other. Methods 180 PLWH self-reported internalized HIV stigma, ART adherence, HIV treatment self-efficacy, and concerns about being seen while taking HIV medication. We calculated bias-corrected 95% confidence intervals (CIs) for indirect effects using bootstrapping to conduct mediation analyses. Results Adherence self-efficacy mediated the relationship between internalized stigma and ART adherence. Additionally, self-efficacy and concern about being seen while taking HIV medication uniquely mediated and explained almost all of the stigma – adherence association in independent paths (parallel mediation). Conclusion These results can inform intervention strategies to promote ART adherence. PMID:27926668

    The aim of the present study was to reveal any association of sexual practice with knowledge about sex education, reproductive physiology and abortion. The study was performed in a non-intervention setting to minimize information bias. A cross-sectional questionnaire was handed out without prior notice to all ninth grade pupils in the Municipality of Viborg, Denmark, in 2007. We found that sexual debut was associated with a greater probability of knowing that chlamydia is the most common sexually transmitted infection (STI). Knowledge of chlamydia was strongly associated with knowledge about the first symptom of pregnancy. A high general level of knowledge of STI was associated with the father being the source of the knowledge among pupils who had not yet had their sexual debut (p < 0.04) and among girls (p < 0.04). The general of knowledge of STI was associated with knowing the first signs of pregnancy and the criteria for legal abortion. A high level of knowledge of STI was significantly associated with the use of contraceptives to avoid pregnancy. The vast majority of condom users (81% compared to 56% of pill users) stated protection against STI as a reason for using contraception (p < 0.006). Concern about the partner's opinion was more outspoken among condom users than among pill users (19% versus 6%, condom versus pill users, p < 0.035). Discrepancy between sexual knowledge and practice is a fact. The discrepancy, however, varies according to sexual experience, gender and whether the respondent's actual behaviour aimed at avoiding unwanted pregnancy or STI.

    Purpose: The purpose of this study was to investigate key factors associated with the economic sustainability of the Registered Dental Hygienist in Alternative Practice (RDHAP). Methods: An invitation to participate in a 38-question electronic survey was sent via postal mail to 440 RDHAP licentiate addressees obtained through the Dental Hygiene Committee of California (DHCC). Legal restrictions did not allow for obtaining the RDHAP licentiate email addresses from the DHCC. The survey was disseminated via email to the 254 RDHAPs who were members of the California Dental Hygienists' Association. Additional invitations to participate were made via flyer distribution at an RDHAP symposium, and on RDHAP only social media sites. Results: The response rate was an estimated 16%. While 44% of the RDHAPs reported some employment in a traditional dental practice, given the opportunity, 61% of these respondents indicated that they would practice exclusively as an RDHAP. With regard to practice strategic planning and alliances, 31% felt that dentists lacked knowledge of the RDHAP, and 25% indicated dentists were resistant to this workforce model. Regarding RDHAP practice staffing patterns, 75% indicated not having any employees. When asked about business systems, 64% had solo, portable practices and 16% had standalone practices. Economic sustainability challenges included practice business/equipment expenses (29%), insurance/reimbursement issues (21%), patient flow (19%) and RDHAP visibility (14%). Conclusions: RDHAP practices face challenges including the need for strategic planning and intra- and inter-professional alliances, efficient and effective patient flow, optimal staffing patterns and effective business systems. Focus on enhancing RDHAP visibility within the dental and medical communities should be a priority. In addition, further research should explore RDHAPs aligning with community-based clinics, Federally Qualified Health Centers and Dental Support Organizations

    Preventive medical care may reduce downstream medical costs and reduce population burden of disease. However, although social, demographic, and geographic determinants of preventive care have been studied, there is little information about how the workplace affects preventive care utilization. This study examines how four types of organizational policies and practices (OPPs) are associated with individual workers' preventive care utilization. We used data collected in 2012 from 838 hospital patient care workers, grouped in 84 patient care units at two hospitals in Boston. Via survey, we assessed individuals' perceptions of four types of OPPs on their work units. We linked the survey data to a database containing detailed information on medical expenditures. Using multilevel models, we tested whether individual-level perceptions, workgroup-average perceptions, and their combination were associated with individual workers' preventive care utilization (measured by number of preventive care encounters over a two-year period). Adjusting for worker characteristics, higher individual-level perceptions of workplace flexibility were associated with greater preventive care utilization. Higher average unit-level perceptions of people-oriented culture, ergonomic practices, and flexibility were associated with greater preventive care utilization. Overall, we find that workplace policies and practices supporting flexibility, ergonomics, and people-oriented culture are associated with positive preventive care-seeking behavior among workers, with some policies and practices operating at the individual level and some at the group level. Improving the work environment could impact employers' health-related expenditures and improve workers' health-related quality of life. Copyright © 2018 Elsevier Inc. All rights reserved.

    To identify determinants of practice nurses' intention to implement a new smoking cessation intervention and to investigate the independent value of attitude and Rogers' innovation characteristics. While effective smoking cessation interventions exist, implementation is often suboptimal. No previous studies have disentangled the independent value of beliefs towards implementation and innovation characteristics in explaining implementation. A cross-sectional descriptive study. In 2010, 56 of 91 general practice nurses who participated in an intervention effectiveness trial completed an online questionnaire concerning demographics, patient population characteristics, attitude, innovation characteristics, self-efficacy, perceived social influence and intention to implement the intervention in the future. Recruitment success during the trial was defined as the number of patients participating. To detect differences between intending and non-intending practice nurses, independent sample t-tests and Chi-squared tests were conducted. Correlation coefficients were calculated to identify associations between potential determinants of intention. To identify significant determinants logistic hierarchical regression analyses were conducted. Innovation characteristics and attitude were both significantly associated with practice nurses' intention to implement. While recruitment success showed a significant positive association with intention, perceived patient support was only a significant determinant when including innovation characteristics or attitude. To increase new interventions' implementation rates, it is most important to convince health professionals of its beneficial characteristics, to generate a positive attitude towards the intervention, to aid practice nurses in recruiting smoking patients and to increase perceived patient support. © 2013 John Wiley & Sons Ltd.

    Vitiligo is an autoimmune disease, characterized by progressive loss of skin pigmentation, which is caused by the interactions of multiple factors, such as heredity, immunity and environment. Recently, a single nucleotide polymorphism (SNP) rs638893 at 11q23.3 region was identified as a risk factor for vitiligo in genome-wide association studies and multiple SNPs in this region have been associated with other autoimmune diseases. This study aims to identify additional susceptibility variants associated with vitiligo at 11q23.3 in the Chinese Han population. We selected and genotyped 26 SNPs at 11q23.3 in an independent cohort including 2924 cases and 4048 controls using the Sequenom MassArray iPLEX ® system. Bonferroni adjustment was used for multiple comparisons and P value <1.92×10 -3 (0.05/26) was considered statistically significant. The A allele of rs613791 and G allele of rs523604 located in CXCR5 were observed to be significantly associated with vitiligo (OR=1.21, 95% CI: 1.11-1.31, P=1.20×10 -5 ; OR=1.14, 95% CI: 1.07-1.23, P=1.90×10 -4 , respectively). The C allele of rs638893 (a previously reported one) located upstream of DDX6 was also significantly associated with vitiligo (OR=1.25, 95% CI: 1.12-1.38, P=3.04×10 -5 ). The genotypes distribution of 3 SNPs also showed significant differences between case and control (rs613791: P=7.00×10 -6 , rs523604: P=4.00×10 -3 , rs638893: P=1.20×10 -5 , respectively). The two newly identified SNPs (rs613791 and rs523604) showed independent associations with vitiligo by linkage disequilibrium analysis and conditional logistic regression. The study identified two new independent signals in the associated locus 11q23.3 for vitiligo. The presence of multiple independent variants emphasizes an important role of this region in disease susceptibility. Copyright © 2017 Japanese Society for Investigative Dermatology.

    Background: Substantial interindividual variability exists in the maximal rate of fat oxidation (MFO) during exercise with potential implications for metabolic health. Although the diet can affect the metabolic response to exercise, the contribution of a self-selected diet to the interindividual variability in the MFO requires further clarification. Objective: We sought to identify whether recent, self-selected dietary intake independently predicts the MFO in healthy men and women. Design: The MFO and maximal oxygen uptake ([Formula: see text]O 2 max) were determined with the use of indirect calorimetry in 305 healthy volunteers [150 men and 155 women; mean ± SD age: 25 ± 6 y; body mass index (BMI; in kg/m 2 ): 23 ± 2]. Dual-energy X-ray absorptiometry was used to assess body composition with the self-reported physical activity level (SRPAL) and dietary intake determined in the 4 d before exercise testing. To minimize potential confounding with typically observed sex-related differences (e.g., body composition), predictor variables were mean-centered by sex. In the analyses, hierarchical multiple linear regressions were used to quantify each variable's influence on the MFO. Results: The mean absolute MFO was 0.55 ± 0.19 g/min (range: 0.19-1.13 g/min). A total of 44.4% of the interindividual variability in the MFO was explained by the [Formula: see text]O 2 max, sex, and SRPAL with dietary carbohydrate (carbohydrate; negative association with the MFO) and fat intake (positive association) associated with an additional 3.2% of the variance. When expressed relative to fat-free mass (FFM), the MFO was 10.8 ± 3.2 mg · kg FFM -1 · min -1 (range: 3.5-20.7 mg · kg FFM -1 · min -1 ) with 16.6% of the variability explained by the [Formula: see text]O 2 max, sex, and SRPAL; dietary carbohydrate and fat intakes together explained an additional 2.6% of the variability. Biological sex was an independent determinant of the MFO with women showing a higher MFO [men: 10.3

    Tumor-microenvironment interactions are increasingly recognized to influence tumor progression. To understand the competitive dynamics of tumor cells in diverse microenvironments, we experimentally parameterized a hybrid discrete-continuum mathematical model with phenotypic trait data from a set of related mammary cell lines with normal, transformed, or tumorigenic properties. Surprisingly, in a resource-rich microenvironment, with few limitations on proliferation or migration, transformed (but not tumorigenic) cells were most successful and outcompeted other cell types in heterogeneous tumor simulations. Conversely, constrained microenvironments with limitations on space and/or growth factors gave a selective advantage to phenotypes derived from tumorigenic cell lines. Analysis of the relative performance of each phenotype in constrained versus unconstrained microenvironments revealed that, although all cell types grew more slowly in resource-constrained microenvironments, the most aggressive cells were least affected by microenvironmental constraints. A game theory model testing the relationship between microenvironment resource availability and competitive cellular dynamics supports the concept that microenvironmental independence is an advantageous cellular trait in resource-limited microenvironments.

    Debt repayment, professional negotiation and practice management skills are vital to a successful medical practice, yet are undervalued and seldom taught in graduate medical education. Medical residents need additional training to confidently transition to independent practice, requiring the development of novel curricula. Medical residents need additional training to confidently transition to independent practice METHODS: We developed a trial practice management curriculum to educate senior residents and fellows through voluntary workshops. Topics discussed in the workshops included debt repayment, billing compliance, medical malpractice, contract negotiations, and lifestyle and financial management. Resident self-confidence was assessed, and feedback was obtained through voluntary survey responses before and after attendance at a workshop, scored using a Likert scale. Twenty-five residents from 20 specialties attended a 1-day session incorporating all lectures; 53 residents from 17 specialties attended a re-designed quarterly session with one or two topics per session. Survey evaluations completed before and after the workshop demonstrated an improvement in residents' self-assessment of confidence in contract negotiations (p < 0.001) and their first year in practice (p < 0.001): after the curriculum, 94 per cent (n = 42) of respondents felt confident participating in contract negotiations, and 93 per cent (n = 38) of respondents felt confident about their first year in practice. One hundred per cent of respondents agreed that the presentation objectives were relevant to their needs as residents. Participant responses indicated a need for structured education in practice management for senior trainees. Senior residents and fellows will benefit most from curricula, but have high familial and professional demands on their schedules. © 2017 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

    Objective To identify practice strategies associated with higher flu vaccination rates in primary care. Design Logistic regression analysis of data from a cross-sectional online questionnaire. Setting 795 general practices across England. Participants 569 practice managers, 335 nursing staff and 107 general practitioners. Primary outcome measures Flu vaccination rates achieved by each practice in different groups of at-risk patients. Results 7 independent factors associated with higher vaccine uptake were identified. Having a lead staff member for planning the flu campaign and producing a written report of practice performance predicted an 8% higher vaccination rate for at-risk patients aged <65 years (OR 1.37, 95% CI 1.10 to 1.71). These strategies, plus sending a personal invitation to all eligible patients and only stopping vaccination when Quality and Outcomes Framework targets are reached, predicted a 7% higher vaccination rate (OR 1.45, 95% CI 1.10 to 1.92) in patients aged ≥65 years. Using a lead member of staff for identifying eligible patients, with either a modified manufacturer's or in-house search programme for interrogating the practice IT system, independently predicted a 4% higher vaccination rate in patients aged ≥65 years (OR 1.22, 95% CI 1.06 to 1.41/OR 1.20, 95% CI 1.03 to 1.40). The provision of flu vaccine by midwives was associated with a 4% higher vaccination rate in pregnant women (OR 1.19, 95% CI 1.02 to 1.40). Conclusions Clear leadership, effective communication about performance and methods used to identify and contact eligible patients were independently associated with significantly higher rates of flu vaccination. Financial targets appear to incentivise practices to work harder to maximise seasonal influenza vaccine uptake. The strategies identified here could help primary care providers to substantially increase their seasonal flu vaccination rates towards or even above the Chief Medical Officer's targets.

    Using baseline data from a randomized controlled pediatric obesity prevention trial, this study sought to examine general parenting style as a potential moderator of the association between feeding-specific parenting practices and child dietary intake. Four hundred and twenty-one parent-child dyads served as participants (49% girls and 93% mothers). Children were, on average, 6.6 years old and either overweight or at-risk for overweight (mean BMI percentile = 84.9). Data were collected in participants' homes. Study staff measured children's height and weight. Parents completed questionnaires designed to assess general parenting styles (authoritative, authoritarian and permissive) and child feeding practices (restriction and monitoring). Child dietary intake was assessed using a 24-h recall system. Outcomes were daily servings of fruits and vegetables, sugar-sweetened beverages (SSB), and unhealthy snacks. Results were as follows: Permissive parenting was inversely associated with fruit and vegetable consumption, and parental monitoring was inversely associated with SSB consumption. There were no other main effects of parenting style or feeding practice on child dietary consumption. Authoritarian parenting moderated the association between restriction and SSB intake (a marginally significant effect after correcting for multiple comparisons). Restriction was inversely associated with SSB consumption when authoritarianism was high but unassociated with SSB consumption when authoritarianism was low. Findings indicate that the parenting practice of monitoring child dietary intake was associated with more healthful consumption regardless of parenting style; interventions may thus benefit from encouraging parental monitoring. The parenting strategy of restricting child dietary intake, in contrast, was associated with lower SSB intake in the context of higher parental authoritarianism but inconsequential in the context of lower parental authoritarianism.

    Heart failure and increased arterial stiffness are associated with declining renal function. Few studies have evaluated the association between left ventricular ejection fraction (LVEF) and brachial-ankle pulse-wave velocity (baPWV) and renal function progression. The aim of this study was to assess whether LVEF<40% and baPWV are associated with a decline in the estimated glomerular filtration rate (eGFR) and the progression to a renal end point of ≥25% decline in eGFR. This longitudinal study included 167 patients. The baPWV was measured with an ankle-brachial index-form device. The change in renal function was estimated by eGFR slope. The renal end point was defined as ≥25% decline in eGFR. Clinical and echocardiographic parameters were compared and analyzed. After a multivariate analysis, serum hematocrit was positively associated with eGFR slope, and diabetes mellitus, baPWV (P=0.031) and LVEF<40% (P=0.001) were negatively associated with eGFR slope. Forty patients reached the renal end point. Multivariate, forward Cox regression analysis found that lower serum albumin and hematocrit levels, higher triglyceride levels, higher baPWV (P=0.039) and LVEF<40% (P<0.001) were independently associated with progression to the renal end point. Our results show that LVEF<40% and increased baPWV are independently associated with renal function decline and progression to the renal end point.

    The literature of action control claims that humans control their actions in two ways. In the stimulus-based approach, actions are triggered by external stimuli. In the ideomotor approach, actions are elicited endogenously and controlled by the intended goal. In the current study, our purpose was to investigate whether these two action control modes affect task-switching differently. We combined a classical task-switching paradigm with action-effect learning. Both experiments consisted of two experimental phases: an acquisition phase, in which associations between task, response and subsequent action effects were learned and a test phase, in which the effects of these associations were tested on task performance by presenting the former action effects as preceding effects, prior to the task (called practiced effects). Subjects either chose freely between tasks (ideomotor action control mode) or they were cued as to which task to perform (sensorimotor action control mode). We aimed to replicate the consistency effect (i.e., task is chosen according to the practiced task-effect association) and non-reversal advantage (i.e., better task performance when the practiced effect matches the previously learned task-effect association). Our results suggest that participants acquired stable action-effect associations independently of the learning mode. The consistency effect (Experiment 1) could be shown, independent of the learning mode, but only on the response-level. The non-reversal advantage (Experiment 2) was only evident in the error rates and only for participants who had practiced in the ideomotor action control mode. PMID:29387027

    To identify associations between structure-related and non-responsive feeding practices and children's eating behaviors. Cross-sectional online survey design. Parents (n = 413) of 1- to 10-year-old children. Parental feeding practices and child eating behaviors were measured via the validated Feeding Practices and Structure and Children's Eating Behaviour questionnaires. Associations between parental feeding practices and children's eating behaviors were tested using hierarchical multivariable linear regression models, adjusted for covariates. Feeding practices accounted for 28% and 21% of the variance in food fussiness and enjoyment of food, respectively (P < .001). For all other eating behaviors the amount of variance explained by feeding practices was < 10% (P < .001). Key findings were that more structure and less non-responsive practices were associated with lower food fussiness and higher enjoyment of food. Overall, the findings suggested that mealtime structure and responsive feeding are associated with more desirable eating behaviors. Contrary to predictions, there was no evidence to indicate that these practices are associated with better self-regulation of energy intake. Longitudinal research and intervention studies are needed to confirm the importance of these feeding practices for children's eating behaviors and weight outcomes.

    Endothelial dysfunction of coronary and peripheral arteries has been demonstrated in patients with chronic heart failure (CHF) and appears to be associated with functional implications. However, it is unknown whether endothelial dysfunction in CHF is independently associated with impaired outcome or progression of the disease. We assessed the follow-up of 67 consecutive patients with CHF [New York Heart Association (NYHA) functional class II-III] in which flow-dependent, endothelium-mediated vasodilation (FDD) of the radial artery was assessed by high resolution ultrasound. The primary endpoint was defined by cardiac death, hospitalization due to worsening of heart failure (NYHA class IV, pulmonary oedema), or heart transplantation. Cox regression analysis was used to determine whether FDD was associated with these heart failure-related events. During a median follow-up of 45.7 months 24 patients had an event: 18 patients were hospitalized due to worsening of heart failure or heart transplantation, six patients died for cardiac reasons. Cox regression analysis demonstrated that FDD (P<0.01), diabetes mellitus (P<0.01), and ejection fraction (P<0.01) were independent predictive factors for the occurrence of the primary endpoint. The Kaplan-Meier survival curve revealed a significantly better clinical outcome in patients with FDD above the median (6.2%) compared with those with FDD below the median (P<0.013). These observations suggest that endothelium-mediated vasodilation represents an independent predictor of cardiac death and hospitalization in patients with CHF, consistent with the notion that endothelium-derived nitric oxide may play a protective role in heart failure.

    There is limited literature on hypernatreamia in the setting of hyperglycaemic crisis. This is despite the fact that the presence of hypernatreamia may impact on the classification of hyperglycaemic crisis and its management particularly with regards to the nature of fluid therapy. We determined the prevalence of hypernatreamia and its associated factors at presentation for hyperglycaemic crisis. This was a retrospective review of data for hyperglycaemic crisis admissions in Nelson Mandela Academic Hospital, Mthatha, South Africa. The prevalence of hypernatreamia (uncorrected Serum Sodium at presentation >145 mmol/L) was determined. Hyperosmolality was defined by calculated effective osmolality >320 mosmols/Kg. Multivariate logistic regression was undertaken using variables that were statistically significant in univariate analysis to ascertain those that were independently associated (Odds Ratio (OR) with 95% Confidence Interval (CI)) with hypernatreamia. The prevalence of hypernatreamia in our admissions for hyperglycaemic crisis was 11.7% (n = 32/273 including 171 females and 102 males). All admissions with hypernatreamia met the criteria for hyperosmolality. Age ≥ 60 years (OR = 3.9 95% CI 1.3-12.3; P = 0.018), Altered level of consciousness (OR = 8.8 95% CI 2.3-32.8; P < 0.001) and a new diagnosis of diabetes (OR = 3.7 95%CI 1.2-11.5; P = 0.025) were independently associated with hypernatreamia. The prevalence rate of hypernatreamia in hyperglycaemic admissions was high with all hypernatreamic admissions meeting the criteria for hyperosmolality. Advanced age, altered conscious level and a new diagnosis of diabetes were independently associated with hypernatreamia.

    Although the numbers of Arab American immigrant youth in schools is increasing, there is little understanding of their mental health and the sociocultural factors that might influence it. This study examined the relationship between 2 sociocultural factors (i.e., acculturative stress and religious practices) and internalizing symptoms in first- and second-generation Muslim Arab American adolescents. Adolescents (n = 88) ages 11 to 18 completed measures related to acculturative stress, religious practices, internalizing symptoms, and general demographic information. Results of multiple regression analyses found that acculturative stress significantly predicted internalizing symptoms. Gender was found to moderate this association. No differences in the reported acculturative stress and internalizing symptoms were found between youth of different generational status (i.e., first- vs. second-generation). Finally, adolescents' organizational religious practices, but not their private religious practices, were found to be associated with lower acculturative stress. Implications are discussed related to how school psychologists can provide culturally responsive services to this population. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    Neighborhood and psychosocial variables are related to physical activity (PA), yet interactions between these factors in predicting PA are infrequently studied. This analysis examines the independent associations and interactions between self-reported neighborhood and psychosocial variables in relation to moderate to vigorous PA (MVPA) among adults from a US panel sample. In adjusted models, neighborhood social capital was positively associated with meeting MVPA guidelines. Fewer barriers, greater self-efficacy, and greater autonomous motivation also corresponded with greater odds of meeting MVPA guidelines. An interaction between social capital and autonomous motivation showed that social capital was only associated with MVPA when autonomous motivation was high. Participants who reported both high autonomous motivation and high social capital were most likely to meet MVPA guidelines. Neighborhood social capital, barriers, self-efficacy, and autonomous motivation may be important correlates in promoting adults' PA. Future directions include using objective neighborhood and PA data in similar analyses and investigating associations of neighborhood and psychosocial variables with multiple PA activities. Intervention research to promote PA should also examine whether effects of interventions targeting psychosocial constructs are moderated by features of an individual's neighborhood or whether perceived social capital can be addressed in interventions in conjunction with psychosocial variables.

  10. Increased waist circumference is independently associated with hypothyroidism in Mexican Americans: replicative evidence from two large, population-based studies

    PubMed Central

    2014-01-01

    Background Mexican Americans are at an increased risk of both thyroid dysfunction and metabolic syndrome (MS). Thus it is conceivable that some components of the MS may be associated with the risk of thyroid dysfunction in these individuals. Our objective was to investigate and replicate the potential association of MS traits with thyroid dysfunction in Mexican Americans. Methods We conducted association testing for 18 MS traits in two large studies on Mexican Americans – the San Antonio Family Heart Study (SAFHS) and the National Health and Nutrition Examination Survey (NHANES) 2007–10. A total of 907 participants from 42 families in SAFHS and 1633 unrelated participants from NHANES 2007–10 were included in this study. The outcome measures were prevalence of clinical and subclinical hypothyroidism and thyroid function index (TFI) – a measure of thyroid function. For the SAFHS, we used polygenic regression analyses with multiple covariates to test associations in setting of family studies. For the NHANES 2007–10, we corrected for the survey design variables as needed for association analyses in survey data. In both datasets, we corrected for age, sex and their linear and quadratic interactions. Results TFI was an accurate indicator of clinical thyroid status (area under the receiver-operating-characteristic curve to detect clinical hypothyroidism, 0.98) in both SAFHS and NHANES 2007–10. Of the 18 MS traits, waist circumference (WC) showed the most consistent association with TFI in both studies independently of age, sex and body mass index (BMI). In the SAFHS and NHANES 2007–10 datasets, each standard deviation increase in WC was associated with 0.13 (p < 0.001) and 0.11 (p < 0.001) unit increase in the TFI, respectively. In a series of polygenic and linear regression models, central obesity (defined as WC ≥ 102 cm in men and ≥88 cm in women) was associated with clinical and subclinical hypothyroidism independent of age, sex, BMI and

    Background Systemic lupus erythematosus (SLE) is associated with severe cardiovascular complications. The T50 score is a novel functional blood test quantifying calcification propensity in serum. High calcification propensity (or low T50) is a strong and independent determinant of all-cause mortality in various patient populations. Methods A total of 168 patients with ≥ 4 American College of Rheumatology (ACR) diagnostic criteria from the Swiss Systemic lupus erythematosus Cohort Study (SSCS) were included in this analysis. Serum calcification propensity was assessed using time-resolved nephelometry. Results The cohort mainly consisted of female (85%), middle-aged (43±14 years) Caucasians (77%). The major determinants of T50 levels included hemoglobin, serum creatinine and serum protein levels explaining 43% of the variation at baseline. Integrating disease activity (SELENA-SLEDAI) into this multivariate model revealed a significant association between disease activity and T50 levels. In a subgroup analysis considering only patients with active disease (SELENA-SLEDAI score ≥4) we found a negative association between T50 and SELENA-SLEDAI score at baseline (Spearman’s rho -0.233, P = 0.02). Conclusions Disease activity and T50 are closely associated. Moreover, T50 levels identify a subgroup of SLE patients with ongoing systemic inflammation as mirrored by increased disease activity. T50 could be a promising biomarker reflecting SLE disease activity and might offer an earlier detection tool for high-risk patients. PMID:29364894

    Job satisfaction and organizational attributes in primary care teams are important issues as they affect clinical outcomes and the quality of health care provided. As practice assistants are an integral part of these teams it is important to gain insight into their views on job satisfaction and organizational attributes. The aim of this study was to evaluate the job satisfaction of practice assistants and the organizational attributes within their general practices in Germany and to explore the existence of possible associations. This observational study was based on a job satisfaction survey and measurement of organizational attributes in general practices in the German federal state of Baden-Wuerttemberg. Job satisfaction was measured with the 10-item 'Warr-Cook-Wall job satisfaction scale'. Organizational attributes were evaluated with the 21-items 'survey of organizational attributes for primary care' (SOAPC). Linear regression analyses were performed in which each of SOAPC scales and the overall score of SOAPC was treated as outcome variables. 586 practice assistants out of 794 respondents (73.8%) from 234 general practices completed the questionnaire. Practice assistants were mostly satisfied with their colleagues and least of all satisfied with their income and recognition for their work. The regression analysis showed that 'freedom of working method' and 'recognition of work', the employment status of practice assistants and the mode of practice were almost always significantly associated with each subscale and overall score of SOAPC. Job satisfaction is highly associated with different aspects of organizational attributes for primary care ('communication', 'decision-making' and 'stress'). Consequently, improved job satisfaction could lead to a better-organized primary care team. This implication should be investigated directly in further intervention studies with a special focus on improving the recognition for work and income.

    Yoga is an activity that aims to integrate physical, mental and spiritual elements and is an increasingly popular approach to enhancing physical fitness. The integration of imagery within yoga practice is considered an important component and may be critical in contributing to the benefits of yoga that have been reported. In this study, we tested whether individuals who practice yoga demonstrate superior performance on an objective measure of implicit motor imagery. Thirty-six participants (18 yoga, 18 non-yoga) matched for age, sex and handedness, undertook the hand laterality recognition task; an objective measure of implicit motor imagery performance. Accuracy and response times were gathered and analysed to determine any group differences as well as any differences relating to the typical hallmarks of imagery (i.e. dominance and awkwardness effects) on the task. Response Times (RTs) in the yoga group were significantly faster than controls (p < 0.05) and there was also a trend towards greater accuracy for the Yoga group (p = 0.073). Dominance effects (faster responses to images corresponding with the dominant limb) and Awkwardness effects (faster responses to images corresponding with natural compared with awkward postures) were evident across groups, supporting the participants' use of motor imagery in undertaking the task. Additionally, a Group × Awkwardness interaction (p < 0.05) revealed that the enhanced imagery performance for the yoga group was most pronounced for awkward postures. This is the first study to show that yoga practice is associated with superior motor imagery performance; an association that may be important in explaining the established rehabilitative value of yoga for chronic pain.

  16. Transferability of Dual-Task Coordination Skills after Practice with Changing Component Tasks

    2017-01-01

    Recent research has demonstrated that dual-task performance with two simultaneously presented tasks can be substantially improved as a result of practice. Among other mechanisms, theories of dual-task practice-relate this improvement to the acquisition of task coordination skills. These skills are assumed (1) to result from dual-task practice, but not from single-task practice, and (2) to be independent from the specific stimulus and response mappings during the practice situation and, therefore, transferable to new dual task situations. The present study is the first that provides an elaborated test of these assumptions in a context with well-controllable practice and transfer situations. To this end, we compared the effects of dual-task and single-task practice with a visual and an auditory sensory-motor component task on the dual-task performance in a subsequent transfer session. Importantly, stimulus and stimulus-response mapping conditions in the two component tasks changed repeatedly during practice sessions, which prevents that automatized stimulus-response associations may be transferred from practice to transfer. Dual-task performance was found to be improved after practice with the dual tasks in contrast to the single-task practice. These findings are consistent with the assumption that coordination skills had been acquired, which can be transferred to other dual-task situations independently on the specific stimulus and response mapping conditions of the practiced component tasks.

    Deep venous thrombosis (DVT) is common among trauma patients. If left untreated it may result in lethal pulmonary thromboembolism. Previous studies have suggested that intracranial hemorrhage serves as an independent risk factor for the development of DVT. These studies were not able to exclude anticoagulation therapy as a confounding variable in their analysis. Our objective was to determine the association of traumatic brain injury (TBI) to the formation of DVT irrespective of the use of anticoagulation therapy. All patients admitted to an academic level I Trauma Center between 2000 and 2007 with blunt or penetrating injuries were selected for inclusion in this study. Patients who died or who were discharged within 24 hours of admission were excluded in the analysis. TBI was defined as any intraparenchymal hemorrhage or extra-axial intracranial bleeding identified on radiographic imaging or both. Anticoagulation therapy was defined as the uninterrupted use of either subcutaneous lovenox or heparin. Risk ratios and 95% confidence intervals compared the risk of DVT among patients with and without TBI according to the initiation of anticoagulation therapy (no therapy, <24 hours, 24-48 hours, and >48 hours) adjusted for age, gender, race, injury severity, mechanism of injury, spinal injury, and lower extremity fracture. Irrespective of the time of initiation of pharmacologic prophylaxis, TBI is independently associated with the formation of DVT. A threefold to fourfold increased risk of DVT formation is consistent across all prophylaxis groups among patients with TBI. The incidence of DVT among injured patients with TBI is significantly higher than those patients without head injury independent of anticoagulation therapy. Rigorous surveillance to detect DVT among trauma patients with TBI should be undertaken and where appropriate alternate means for pulmonary thromboembolism prevention used.

    Practicing a musical instrument is associated with cognitive benefits and structural brain changes in correlational and interventional trials; however, the effect of musical training on cognition during childhood is still unclear. In this longitudinal study of child development we analyzed the association between musical practice and performance on reasoning, processing speed and working memory (WM) during development. Subjects (n = 352) between the ages of 6 and 25 years participated in neuropsychological assessments and neuroimaging investigations (n = 64) on two or three occasions, 2 years apart. Mixed model regression showed that musical practice had an overall positive association with WM capacity (visuo-spatial WM, F = 4.59, p = 0.033, verbal WM, F = 9.69, p = 0.002), processing speed, (F = 4.91, p = 0.027) and reasoning (Raven's progressive matrices, F = 28.34, p < 0.001) across all three time points, after correcting for the effect of parental education and other after school activities. Music players also had larger gray matter volume in the temporo-occipital and insular cortex (p = 0.008), areas previously reported to be related to musical notation reading. The change in WM between the time points was proportional to the weekly hours spent on music practice for both WM tests (VSWM, β = 0.351, p = 0.003, verbal WM, β = 0.261, p = 0.006) but this was not significant for reasoning ability (β = 0.021, p = 0.090). These effects remained when controlling for parental education and other after school activities. In conclusion, these results indicate that music practice positively affects WM development and support the importance of practice for the development of WM during childhood and adolescence.

  19. Source-dependent and source-independent controls on plutonium oxidation state and colloid associations in groundwater.

    Plutonium (Pu) was characterized for its isotopic composition, oxidation states, and association with colloids in groundwater samples near disposal basins in F-Area of the Savannah River Site and compared to similar samples collected six years earlier. Two sources of Pu were identified, the disposal basins, which contained a 24Pu/l39Pu isotopic signature consistent with weapons grade Pu, and 244Cm, a cocontaminant that is a progenitor radionuclide of 24Pu. 24Pu that originated primarily from 244Cm tended to be appreciably more oxidized (Pu(V/VI)), less associated with colloids (approximately 1 kDa - 0.2 microm), and more mobile than 239Pu, as suggested by our prior studies at this site. This is not evidence of isotope fractionation but rather "source-dependent" controls on 240Pu speciation which are processes that are not at equilibrium, i.e., processes that appear kinetically hindered. There were also "source-independent" controls on 239Pu speciation, which are those processes that follow thermodynamic equilibrium with their surroundings. For example, a groundwater pH increase in one well from 4.1 in 1998 to 6.1 in 2004 resulted in an order of magnitude decrease in groundwater 239Pu concentrations. Similarly, the fraction of 239Pu in the reduced Pu(III/IV) and colloidal forms increased systematically with decreases in redox condition in 2004 vs 1998. This research demonstrates the importance of source-dependent and source-independent controls on Pu speciation which would impact Pu mobility during changes in hydrological, chemical, or biological conditions on both seasonal and decadal time scales, and over short spatial scales. This implies more dynamic shifts in Pu speciation, colloids association, and transport in groundwater than commonly believed.

    Although survival of patients with in-hospital cardiac arrest varies markedly among hospitals, specific resuscitation practices that distinguish sites with higher cardiac arrest survival rates remain unknown. To identify resuscitation practices associated with higher rates of in-hospital cardiac arrest survival. Nationwide survey of resuscitation practices at hospitals participating in the Get With the Guidelines-Resuscitation registry and with 20 or more adult in-hospital cardiac arrest cases from January 1, 2012, through December 31, 2013. Data analysis was performed from June 10 to December 22, 2015. Risk-standardized survival rates for cardiac arrest were calculated at each hospital and were then used to categorize hospitals into quintiles of performance. The association between resuscitation practices and quintiles of survival was evaluated using hierarchical proportional odds logistic regression models. Overall, 150 (78.1%) of 192 eligible hospitals completed the study survey, and 131 facilities with 20 or more adult in-hospital cardiac arrest cases comprised the final study cohort. Risk-standardized survival rates after in-hospital cardiac arrest varied substantially (median, 23.7%; range, 9.2%-37.5%). Several resuscitation practices were associated with survival on bivariate analysis, although only 3 were significant after multivariable adjustment: monitoring for interruptions in chest compressions (adjusted odds ratio [OR] for being in a higher survival quintile category, 2.71; 95% CI, 1.24-5.93; P = .01), reviewing cardiac arrest cases monthly (adjusted OR for being in a higher survival quintile category, 8.55; 95% CI, 1.79-40.00) or quarterly (OR, 6.85; 95% CI, 1.49-31.30; P = .03), and adequate resuscitation training (adjusted OR, 3.23; 95% CI, 1.21-8.33; P = .02).

    Abstract Background Children's physical activity (PA) is inversely associated with children's weight status. Parents may be an important influence on children's PA by restricting sedentary time or supporting PA. The aim of this study was to investigate the association of PA and screen-media–related [television (TV) and videogame] parenting practices with children's PA. Methods Secondary analyses of baseline data were performed from an intervention with 9- to 12-year-olds who received active or inactive videogames (n=83) to promote PA. Children's PA was assessed with 1 week of accelerometry at baseline. Parents reported their PA, TV, and videogame parenting practices and child's bedroom screen-media availability. Associations were investigated using Spearman's partial correlations and linear regressions. Results Although several TV and videogame parenting practices were significantly intercorrelated, only a few significant correlations existed between screen-media and PA parenting practices. In linear regression models, restrictive TV parenting practices were associated with greater child sedentary time (p=0.03) and less moderate-to-vigorous PA (MVPA; p=0.01). PA logistic support parenting practices were associated with greater child MVPA (p=0.03). Increased availability of screen-media equipment in the child's bedroom was associated with more sedentary time (p=0.02) and less light PA (p=0.01) and MVPA (p=0.05) in all three models. Conclusion In this cross-sectional sample, restrictive screen-media and supportive PA parenting practices had opposite associations with children's PA. Longitudinal and experimental child PA studies should assess PA and screen-media parenting separately to understand how parents influence their child's PA behaviors and whether the child's baseline PA or screen media behaviors affect the parent's use of parenting practices. Recommendations to remove screens from children's bedrooms may also affect their PA. PMID:24028564

    To explore newly graduated nurses' (NGN) perception of their practice environment and its association with their self-assessed competence, turnover intentions and job satisfaction as work-related factors. The impact of practice environment on nurses' work is important. Positive practice environments are associated with positive organisational, nurse and patient outcomes. How this applies to NGNs needs further exploration. A cross-sectional descriptive correlation design was used. Data were collected with PES-NWI and NCS instruments from 318 Finnish registered nurses, and analysed statistically. Newly graduated nurses' perception of their practice environment was mainly positive. Most positive perceptions related to collegial nurse-physician relations, and the least positive to staffing and resource adequacy. Positive perceptions were also associated with higher professional competence, higher perceptions of quality of care and lower intentions to leave the job or profession. The findings revealed strong and significant associations between practice environment and work-related factors. Practice environment is an important element in supporting NGNs' competence, retention and job satisfaction. Nursing management should pay attention to NGNs' perceptions of their practice environment. Management's ability to create and maintain positive practice environments can foster NGNs' professional development and job satisfaction, and consequently retain them in the workforce. © 2015 John Wiley & Sons Ltd.

    As Medicare Part D contracts apply pressure on the profitability of independent pharmacies, there is concern about their owners' willingness to sign such contracts. Identifying factors affecting independent pharmacy owners' satisfaction with Medicare Part D contracts could inform policy makers in managing Medicare Part D. (1) To identify influences on independent pharmacy owners' satisfaction with Medicare Part D contracts and (2) to characterize comments made by independent pharmacy owners about Medicare Part D. This cross-sectional study used a mail survey of independent pharmacy owners in 15 states comprising 6 Medicare regions to collect information on their most- and least-favorable Medicare Part D contracts, including satisfaction, contract management activities, market position, pharmacy operation, and specific payment levels on brand and generic drugs. Of the 1649 surveys mailed, 296 surveys were analyzed. The regression models for satisfaction with both the least and the most-favorable Part D contracts were significant (P<0.05). A different set of significant influences on satisfaction was identified for each regression model. For the most-favorable contract, influences were contending and equity. For the least-favorable contract, influences were negotiation, equity, generic rate bonus, and medication therapy management (MTM) payment. About one-third of the survey respondents made at least 1 comment. The most frequent themes in the comments were that Medicare Part D reimbursement rate is too low (28%) and that contracts are offered without negotiation in a "take it or leave it" manner (20%). Equity, contending, negotiation, generic rate bonus, and MTM payments were identified as the influences of independent pharmacy owners' satisfaction toward Medicare Part D contracts. Generic rate bonus and MTM payment provide additional financial incentives to less financially favorable contracts and, in turn, contribute to independent pharmacy owner's satisfaction

    To investigate whether lactate dehydrogenase A (LDHA), an important component of the LDH tetramer crucial for aerobic glycolysis, is associated with patient outcome and constitutes a therapeutic target in neuroblastoma (NB). Expression of LDHA mRNA and protein was determined in 709 and 110 NB patient samples, respectively, and correlated to survival and risk factors. LDHA and LDHB were depleted in human NB cell lines by CRISPR/Cas9 and shRNA, respectively, and aerobic glycolysis, clonogenicity and tumorigenicity were determined. Expression of LDHA in relation to MYCN was measured in NB cell lines and in the TH-MYCN NB mouse model. Expression of LDHA, both on the mRNA and the protein level, was significantly and independently associated with decreased patient survival. Predominant cytoplasmic localization of LDHA protein was associated with poor outcome. Amplification and expression of MYCN did not correlate with expression of LDHA in NB cell lines or TH-MYCN mice, respectively. Knockout of LDHA inhibited clonogenicity, tumorigenicity and tumor growth without abolishing LDH activity or significantly decreasing aerobic glycolysis. Concomitant depletion of LDHA and the isoform LDHB ablated clonogenicity while not abrogating LDH activity or decreasing aerobic glycolysis. The isoform LDHC was not expressed. High expression of LDHA is independently associated with poor outcome of NB and NB cells can be inhibited by depletion of LDHA or LDHB. This inhibition appears to be unrelated to LDH activity and aerobic glycolysis. Thus, investigations of inhibitory mechanisms beyond attenuation of aerobic glycolysis are warranted, both in NB and normal cells. Copyright ©2018, American Association for Cancer Research.

    US veterans (hereafter, 'veterans') are at risk for being overweight or obese and associated unhealthy behaviours, including poor diet; although limited studies have examined the underlying factors associated with such outcomes. As such, the present study evaluated the association between food insecurity and dietary practices among veterans. A secondary analysis of cross-sectional data from the California Health Interview Survey (2009, 2011/2012) was conducted. Survey weights were applied to identify univariate means, population estimates and weighted percentages. Bivariate analyses followed by survey-weighted negative binomial regression were used to model the association between food insecurity and dietary practices of fruit, vegetable, fast food and soda intakes. California Health Interview Survey 2009-2011/2012. The present study included a total of 11 011 veterans from California. Nearly 5 % of the studied veteran population reported living in poverty with food insecurity. Compared with those at or above the poverty level and those in poverty but food secure, the mean intakes of fruits and vegetables were lower, while the mean intakes of soda and fast foods (P for trend <0·05) were higher among veterans living in poverty with food insecurity. Food insecurity was associated with 24 and 142 % higher average consumption of fast foods and soda, respectively, and 24 % lower fruit intake. Food insecurity remains a burden among veterans and is associated with unhealthy dietary practices. Targeted interventions to improve diet quality are imperative.

Independent factor patterns for the frequency of information collected from the patient for the first diabetes education session showed that educators either focused on patients' self-management practices (exercise and dietary practices, knowledge, and social impacts of diabetes) or issues with learning about self-management, such as understanding the patient's learning style and motivation for managing diabetes. Factor patterns overall showed diverse approaches to working with patients, including strategies used with patients struggling with dietary goals and the importance of tasks to complete during the first patient session. Although most educators reported practices that were largely patient centered as promoted by the American Diabetes Association (ADA) and models of chronic disease management, patterns of practice suggest that diabetes educators vary considerably in how they apply education practices, especially with dietary self-management education.

    Context: Although obesity has been, in general, associated with glomerular hyperfiltration, visceral adiposity has been suggested to be associated with reduced glomerular filtration. Objective: The aim of the study was to evaluate the differential effects of obesity and body fat distribution on glomerular filtration. Design and Setting: We conducted a cross-sectional study of the Japanese-American community in Seattle, Washington. Participants: We studied a representative sample of second-generation Japanese-American men and women with normal glucose tolerance (n = 124) and impaired glucose metabolism (impaired fasting glucose and/or impaired glucose tolerance) (n = 144) residing in King County, Washington. Main Outcome Measures: Glomerular filtration rate was estimated by 24-h urinary creatinine clearance, body size by body mass index (BMI), and intra-abdominal fat (IAF), sc fat (SCF), and lean thigh areas by CT scan. Results: Creatinine clearance was positively correlated with BMI (r = 0.429; P < 0.001), fasting glucose (r = 0.198; P = 0.001), and insulin levels (r = 0.125; P = 0.042), as well as IAF (r = 0.239; P < 0.001), SCF (r = 0.281; P < 0.001), and lean thigh (r = 0.353; P < 0.001) areas. The association between creatinine clearance and BMI remained significant after adjustments for IAF, SCF areas, and fasting insulin levels (r = 0.337; P < 0.001); whereas IAF and SCF areas were not independently associated with creatinine clearance after adjusting for BMI. Creatinine clearance increased with increasing BMI after adjusting for fasting insulin, fasting glucose, IAF and SCF areas in subjects with normal glucose tolerance (r = 0.432; P < 0.001) and impaired glucose metabolism (r = 0.471; P < 0.001). Conclusions: BMI rather than body fat distribution is an independent determinant of creatinine clearance in nondiabetic subjects. Lean body mass, rather than adiposity, may explain this association.

    Medicare Part B physician payment indicates a cost to Medicare beneficiaries for a physician service and connotes physician clinical productivity. The objective of this study was to determine whether there was an association between practice arrangement and Medicare physician payment. Cross-sectional study. Medicare provider utilization and payment data. Otolaryngologists from 1 metropolitan area were included as part of a pilot study. A generalized linear model was used to determine the effect of practice-specific variables including patient volumes on physician payment. Of 67 otolaryngologists included, 23 (34%) provided services through an independent practice, while others were employed by 1 of 3 local academic centers. Median payment was $58,895 per physician for the year, although some physicians received substantially higher payments. Reimbursements to faculty at 1 academic department were higher than to those at other institutions or to independent practitioners. After adjustments were made for patient volumes, physician subspecialty, and gender, payments to each faculty at Hospital C were 2 times higher than to those at Hospital A (relative ratio [RR] 2.03; 95% CI, 1.27-3.27; P = .003); 2 times higher than to faculty at Hospital B (RR 2.04; 95% CI, 1.4-2.7; P = .0001); and 1.6 times higher than to independent practitioners (RR 1.6; 95% CI, 1.04-2.7; P = .03). Payments to physicians in the other groups were not significantly different. Differences in reimbursement corresponded to an emphasis on procedures over office visits but not Medicare case mix adjustments for patient discharges from associated institutions. Variation in the cost of academic otolaryngology care may be subject in part to institutional factors. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

    We have reported previously that intensive preparation for a standardized test that taxes reasoning leads to changes in structural and functional connectivity within the frontoparietal network. Here, we investigated whether reasoning instruction transfers to improvement on unpracticed tests of reasoning, and whether these improvements are associated with changes in neural recruitment during reasoning task performance. We found behavioral evidence for transfer to a transitive inference task, but no evidence for transfer to a rule generation task. Across both tasks, we observed reduced lateral prefrontal activation in the trained group relative to the control group, consistent with other studies of practice-related changes in brain activation. In the transitive inference task, we observed enhanced suppression of task-negative, or default-mode, regions, consistent with work suggesting that better cognitive skills are associated with more efficient switching between networks. In the rule generation task, we found a pattern consistent with a training-related shift in the balance between phonological and visuospatial processing. Broadly, we discuss general methodological considerations related to the analysis and interpretation of training-related changes in brain activation. In summary, we present preliminary evidence for changes in brain activation associated with practice of high-level cognitive skills. PMID:26368278

    Healthcare-associated infections (HAIs) have long been the subject of research and prevention practice. When findings show potential to significantly impact outcomes, clinicians, policymakers, safety experts, and stakeholders seek to bridge the gap between research and practice by identifying mechanisms and assigning responsibility for translating research to practice. This paper describes progress and challenges in HAI research and prevention practices, as explained through an examination of Health and Human Services (HHS) Action Plan's goals, inputs, and implementation in each area. We used the Context-Input-Process-Product evaluation model, together with an HAI prevention system framework, to assess the transformative processes associated with HAI research and adoption of prevention practices. Since the introduction of the Action Plan, HHS has made substantial progress in prioritizing research projects, translating findings from those projects into practice, and designing and implementing research projects in multisite practice settings. Research has emphasized the basic science and epidemiology of HAIs, the identification of gaps in research, and implementation science. The basic, epidemiological, and implementation science communities have joined forces to better define mechanisms and responsibilities for translating HAI research into practice. Challenges include the ongoing need for better evidence about intervention effectiveness, the growing implementation burden on healthcare providers and organizations, and challenges implementing certain practices. Although these HAI research and prevention practice activities are complex spanning multiple system functions and properties, HHS is making progress so that the right methods for addressing complex HAI problems at the interface of patient safety and clinical practice can emerge.

    Later age at onset of independent walking is associated with lower leg bone strength in childhood and adolescence. However, it is unknown whether these associations persist into older age or whether they are evident at axial (central) or upper limb sites. Therefore, we examined walking age obtained at age 2 years and bone outcomes obtained by dual-energy X-ray absorptiometry (DXA) and peripheral quantitative computed tomography (pQCT) scans at ages 60 to 64 years in a nationally representative cohort study of British people, the MRC National Survey of Health and Development. It was hypothesized that later walking age would be associated with lower bone strength at all sites. Later independent walking age was associated with lower height-adjusted hip (standardized regression coefficients with 95% confidence interval [CI] -0.179 [-0.251 to -0.107]), spine (-0.157 [-0.232 to -0.082]), and distal radius (-0.159 [-0.245 to -0.073]) bone mineral content (BMC, indicating bone compressive strength) in men (all p < 0.001). Adjustment for covariates partially attenuated these associations, primarily because of lower lean mass and adolescent sporting ability in later walkers. These associations were also evident for a number of hip geometric parameters (including cross-sectional moment of inertia [CSMI], indicating bone bending/torsional strength) assessed by hip structural analysis (HSA) from DXA scans. Similar height-adjusted associations were also observed in women for several hip, spine, and upper limb outcomes, although adjustment for fat or lean mass led to complete attenuation for most outcomes, with the exception of femoral shaft CSMI and spine bone area (BA). In conclusion, later independent walking age appears to have a lifelong association with bone strength across multiple skeletal sites in men. These effects may result from direct effects of early life loading on bone growth and mediation by adult body composition. Results suggest that late walking age may

    Successful strategies to prevent neonatal acute kidney injury are lacking. Nevertheless, it is well known that in breastfed babies the excretory needs of the kidney are low because the intake of most nutrients is just above the nutritional requirement. This study aimed to determine whether feeding type predicts acute kidney injury in the very low birth weight infant. One hundred and eighty-six infants were enrolled in this pre-post cohort study (114 infants were included in the only human milk-fed group and 72 in the formula-fed group). Routine biological markers of acute kidney injury were collected in both groups from birth to discharge. Compared with formula feeding, human milk feeding was associated with almost 80% lower odds of acute kidney injury (odds ratio [OR] = 0.2; 95% confidence interval [CI], 0.05-0.77). After confounding variables had been controlled for, formula feeding was independently associated with acute kidney injury in very low birth weight infants. The study showed that, at our institution, acute kidney injury in the neonatal period is frequently associated with the avoidable procedure of formula feeding. Further prospective multicenter studies are needed to determine the generality of this association.

    Tuberculosis (TB) remains a major global health problem. The emerging epidemic of multi- and extensively drug-resistant (M/XDR) TB further imperils health workers, patients and public health. Health facilities with inadequate infection control are risky environments for the emergence and transmission of TB. There was no study that presented data on infection control practices of health care workers. This study aimed to assess tuberculosis infection control practices and associated factors among health care workers in West Gojjam Zone, Northwest Ethiopia. Institution based quantitative cross-sectional study triangulated with qualitative observation and key informant interview was conducted. Six hundred sixty two health care workers were selected by multistage random sampling method. Self-administered structured questionnaire was used to collect quantitative data. Observation checklists and key informant interview guides were used to collect qualitative data. Quantitative data were entered in to Epi Info version 3.5.3 and analyzed using SPSS version 20. Odds ratio with 95 % confidence interval was used to identify factors associated with TB infection control practice of health care workers. Qualitative data were translated, transcribed, analyzed and triangulated with the quantitative findings. The proportion of proper TB infection control (TBIC) practices was 38 %. Qualitative data showed that administrative, environmental and personal respiratory protection control measures were not practiced well. Knowledge on the presence of TBIC plan [AOR = 4.25, 95 % CI: 2.46 - 7.35], knowledge on the presence of national guideline [AOR = 8.95, 95 % CI: 4.35 - 18.40] and working department of the health care workers were independent predictors of TBIC practices. The proportion of proper TBIC practices of health care workers was low. TBIC practices were determined by knowing the presence of TBIC plan and national guideline and working department. Hence, supportive

    Non-alcoholic fatty liver disease (NAFLD) has been claimed as a liver phenotype of metabolic syndrome, which in turn is associated with male hypogonadism. We assessed whether an independent association between NAFLD and androgen deficiency could be revealed in men with chronic spinal cord injury (SCI), who exhibit a high prevalence of biochemical androgen deficiency and a combination of risk factors for metabolic syndrome. Fifty-five consecutive men with chronic SCI admitted to a rehabilitation program underwent clinical/biochemical evaluations and liver ultrasonography. NAFLD was diagnosed in 27 patients (49.1%). Men with NAFLD were older and exhibited significantly higher body mass index, Homeostatic model assessment of insulin resistance, triglycerides and gamma-glutamyl transpeptidase values, lower total and free testosterone levels and they were engaged in a significantly poorer weekly leisure time physical activity (LTPA). At the multiple logistic regression analysis, only total and free testosterone levels exhibited a significant independent association with NAFLD. The risk of having NAFLD increased indeed of 1% for each decrement of 1 ng/dL of total testosterone and of 3% for each decrement of 1 pg/mL of free testosterone, after adjustment for confounders. In men with total testosterone < 300 ng/dL (36.4%) the prevalence of NAFLD reached 85%: they had a risk of having NAFLD significantly higher (∼12-fold) than those with total testosterone ≥ 300 ng/dL, after adjustment for confounders. The evidence of an independent association between NAFLD and low testosterone is strongly reinforced by its demonstration in men with chronic SCI, in spite of the many confounders peculiar to this population.

    Metabolic and atherosclerotic diseases are known risk factors for disability in old age, and can result in sarcopenia as well as cognitive impairment, which are both components of frailty syndrome. As muscle loss increases with ageing, it is unclear whether muscle loss per se, or the diseases themselves, are the underlying cause of physical frailty in those suffering from these diseases. We tested the hypothesis that metabolic and atherosclerotic diseases and cognitive impairment are associated with physical frailty independent of muscle loss in old age, and further examined their impact on the relationship between physical frailty and mortality. Prospective. Community. 4000 community dwelling Chinese elderly ≥65 years. Diabetes, hypertension, stroke, heart disease, cognitive impairment, smoking, physical activity, waist hip ratio (WHR) and ankle-brachial index (ABI)) were recorded. Physical frailty measurements (grip-strength, chair-stands, stride length and 6-metre walks) were summarized into a composite frailty score (0-20), 0 being the most frail) according to quartiles of performance. Appendicular muscle mass (ASM) was measured using dual X-ray absorptiometry. Relationships between the score and covariates were analyzed. Cox regression was used to study the impact of metabolic and atnerosclerotic risk factors on the relationship between physical frailty and 6-year mortality. After adjustment for ASM, all metabolic diseases and indexes, and cognitive impairment were significantly associated with the composite physical frailty score in univariate analysis. In multivariate analysis, cognitive impairment, high WHR, diabetes, stroke and heart disease were all independently associated with higher physical frailty with adjustment for age, physical activity level and ASM. Hypertension was associated with physical frailty in men but not in women. In Cox regression, increased physical frailty was associated with higher 6-year mortality. The impact of metabolic and

    Mindfulness-Based Cognitive Therapy (MBCT) and Mindfulness-Based Stress Reduction (MBSR) emphasize the importance of mindfulness practice at home as an integral part of the program. However, the extent to which participants complete their assigned practice is not yet clear, nor is it clear whether this practice is associated with positive outcomes. For this systematic review and meta-analysis, searches were performed using Scopus and PubMed for studies published through to the end of 2015, reporting on formal home practice of mindfulness by MBSR or MBCT participants. Across 43 studies (N = 1427), the pooled estimate for participants' home practice was 64% of the assigned amount, equating to about 30 minutes per day, six days per week [95% CI 60-69%]. There was substantial heterogeneity associated with this estimate. Across 28 studies (N = 898), there was a small but significant association between participants' self-reported home practice and intervention outcomes (r = 0·26, 95% CI 0·19,-0·34). MBSR and MBCT participants report completing substantial formal mindfulness practice at home over the eight-week intervention, albeit less than assigned amounts. There is a small but significant association between the extent of formal practice and positive intervention outcomes for a wide range of participants. Copyright © 2017 The Authors.

    present study indicate that a particular focus needs to be placed on calving and colostrum management because this study has highlighted a number of areas which are below international standards, and may have repercussions for calf health. Furthermore, management practices on larger farms could be improved and, as these represent the future of dairy farming, a focus needs to be placed on them. Expanding herds are not a particular concern as herd expansion, independent of herd size, does not seem to be associated with calving and colostrum management practices on Irish spring-calving dairy herds.

    Research suggests that suicidal behavior in individuals with anxiety disorders is attributable to co-occurring risk factors, such as depression. We argue that these conclusions are founded primarily in statistical adjustments that may obscure independent associations. We explored independent associations between specific anxiety disorders and suicide attempts and ideation by means of propensity score matching, a process that simulates a case-control study by creating matched groups that differ in group status (e.g., diagnosis of a specific anxiety disorder) but that are statistically equivalent on observed covariates. We made use of the National Comorbidity Survey Replication (NCS-R) and the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), which include a total of 43,935 adults. Diagnoses included agoraphobia without panic disorder, generalized anxiety disorder, panic disorder with or without agoraphobia, posttraumatic stress disorder, social anxiety disorder, and specific phobia. Each anxiety disorder was (95% confidence intervals) associated with increased odds of lifetime suicide attempts (odds ratios 3.57-6.64 [NCS-R], 3.03-7.00 [NESARC]) and suicidal ideation (odds ratios 2.62-4.87 [NCS-R], 3.34-10.57 [NESARC]). Odds ratios for each disorder remained statistically significant after matching on diagnostic status of dysthymia, major depressive disorder, alcohol abuse/dependence, substance abuse/dependence, bipolar disorder I, bipolar disorder II, all other anxiety disorders, and on sociodemographic variables. This is the first report to present evidence that each anxiety disorder is associated with suicide ideation and suicide attempts beyond the effects of co-occurring mental disorders. These findings warrant consideration in assessment, intervention, and related policies. © 2013 Wiley Periodicals, Inc.

    The present study aimed to explore the process in which parental food-related behaviors might influence preadolescent children's vegetable consumption, addressing potential mediating effects of child cognitions. Cross-sectional surveys were performed among 10-12-year-olds and their parents. The child questionnaire included measures of vegetable consumption and child cognitions related to vegetable consumption (i.e. attitudes, social influence, self-efficacy and intention). The parent questionnaire included measures of parental feeding practices adapted from the Comprehensive Feeding Practices Questionnaire. Stepwise regressions were performed to reveal potential mediating effects of child cognitions on the associations between parental feeding practices and child vegetable consumption. Our results suggested a mediating effect of child self-efficacy on the association between parental restrictive behavior and child vegetable consumption. Other potential mediating effects were not supported in this study. Copyright © 2013 Elsevier Ltd. All rights reserved.

    2016-12-01

    Load restraint systems in automobile transport utilise tie-down lashings placed over the car's tyres, which are tensioned manually by the operator using a ratchet assembly. This process has been identified as a significant manual handling injury risk. The aim of this study was to gain insight on the current practices associated with tie-down lashings operation, and identify the gaps between current and optimal practice. We approached this with qualitative and quantitative assessments and one numerical simulation to establish: (i) insight into the factors involved in ratcheting; (ii) the required tension to hold the car on the trailer; and (iii) the tension achieved by drivers in practice and associated joint loads. We identified that the method recommended to the drivers was not used in practice. Drivers instead tensioned the straps to the maximum of their capability, leading to over-tensioning and mechanical overload at the shoulder and elbow. We identified the postures and strategies that resulted in the lowest loads on the upper body during ratcheting (using both hands and performing the task with their full body). This research marks the first step towards the development of a training programme aiming at changing practice to reduce injury risks associated with the operation of tie-down lashings in the automobile transport industry. Practitioner Summary: The study investigated current practice associated with the operation of tie-down lashings through qualitative (interviews) and quantitative (biomechanical analysis) methods. Operators tended to systematically over-tension the lashings and consequently overexert, increasing injury risks.

    Objective Adverse changes in lipoprotein particle number and size are common with insulin resistance and are associated with increased cardiovascular risk. Comprehensive information regarding lipoprotein particle number and size, and how these parameters relate to body weight, insulin resistance and hyperandrogenemia is lacking in PCOS. We tested the hypothesis that PCOS is associated with atherogenic changes in lipoprotein profile independent of body weight and examined the role of insulin resistance and androgens in these atherogenic changes. Design Case-control study performed at Clinical Research Center at an Academic Medical Center in United States. Patients and Measurements Fasting Blood was obtained from 25 PCOS and 25 control women of similar age and BMI. Lipoprotein particle number and size was determined by nuclear magnetic resonance and compared between the groups. Results The mean BMI for both groups was less than 30 kg/m2 (P=0.33). Women with PCOS had an increase in VLDL particle number (P=0.005), LDL particle number (P=0.02) and a decrease in HDL size (P=0.04). LDL size was borderline decreased (P=0.09). These differences persisted after adjustment for ethnicity, alcohol and tobacco intake and exercise. In stepwise regression models, bioavailable testosterone was the only predictor of LDL cholesterol, triglyceride, VLDL and LDL particle number. SHBG was the only predictor of LDL and HDL size. Conclusions Independent of body weight, PCOS was associated with changes in lipoprotein profile that increases risk for cardiovascular disease. These changes were present in a mostly non-obese group of women and were more closely related to androgens than fasting insulin. PMID:21521284

    The median life expectancy of cystic fibrosis (CF) patients has increased dramatically over the last few years and we now observe a subset of patients with a body mass index (BMI) exceeding 25 kg/m(2). The aim of this study was to characterize these individuals and to identify factors associated with higher BMI. This is a cross sectional study including 187 adult CF subjects. Percent predicted forced expiratory volume in 1s (%FEV(1)), blood lipid profiles as well as fasting glucose and insulin levels were evaluated. Subjects also had an oral glucose tolerance test (OGTT) and the area under the curve (AUC) for glucose and insulin was calculated. CF subjects were then stratified according to the following BMI categories: underweight: BMI≤18.5 kg/m(2); normal weight: 18.5 kg/m(2)independent associated with BMI. Overweight CF subjects have higher fasting insulin and insulin AUC as well as total and LDL-cholesterol. Furthermore, we also demonstrated that LDL-cholesterol, insulin AUC are independently associated with BMI in a population of adult CF subjects. Copyright © 2012. Published by Elsevier B.V.

    We evaluated the practices used in Thai hospitals to prevent catheter-associated urinary tract infection (CAUTI), central line-associated bloodstream infection (CLABSI), and ventilator-associated pneumonia (VAP). From January 1, 2014-November 30, 2014, we surveyed all Thai hospitals with an intensive care unit and at least 250 beds. The use of prevention practices for CAUTI, CLABSI, and VAP was assessed. High compliance (≥75%) with all components of the CLABSI and VAP prevention bundles were determined. CAUTI, CLABSI, and VAP infection rates before and after implementing infection control practices are reported. Multivariable regression was used to examine associations between infection prevention bundle compliance and infection rate changes. Out of 245 eligible hospitals, 212 (86.5%) responded. A total of 120 (56.6%) and 115 hospitals (54.2%) reported ≥75% compliance for all components of the CLABSI and VAP prevention bundles, respectively, and 91 hospitals (42.9%) reported using ≥ 4 recommended CAUTI-prevention practices. High compliance with all of the CLABSI and VAP bundle components was associated with significant infection rate reductions (CLABSI, 38.3%; P < .001; VAP, 32.0%; P < .001). Hospitals regularly using ≥ 4 CAUTI-prevention practices did not have greater reductions in CAUTI (0.02%; P = .99). Compliance with practices to prevent hospital infections was suboptimal. Policies and interventions promoting bundled approaches may help reduce hospital infections for Thai hospitals.

    Background : High intake of fruit juices and soft drinks contributes to excessive weight gain and obesity in children. Furthermore, parenting practices play an important role in the development of children's dietary habits. The way parents play this role in the development of their children's choices of beverages is still unclear. Objectives : To study the associations: (1) of both fruit juices and soft drinks consumption with water consumption of children and (2) The associations between parenting practices towards fruit juices and soft drinks and water consumption of children. Design : Cross-sectional data from 6 to 8 year old children from seven European communities ( n = 1187) were collected. Associations among fruit juices, soft drinks, the respective parenting practices and the child's water consumption were assessed by parental questionnaires. Results : The consumption of water was inversely associated with that of soft drinks but not with the consumption of fruit juices. The child's water intake was favorably influenced when stricter parenting practices towards soft drinks were adopted (e.g., less parental allowance, low home availability and high parental self-efficacy in managing intake). There was less influence observed of parenting practices towards fruit juices. Fruit juices were consumed more often than soft drinks. Conclusions : Low consumption of soft drinks-and not of fruit juices-was associated with high water consumption in children in the current study. Moreover, parenting practices towards both fruit juices and soft drinks were associated with the water intake of the children, irrespective of their socio-economic status.

    Introduction Childcare educators may be role models for healthy eating and physical activity (PA) behaviours among young children. This study aimed to identify which childcare educators’ practices are associated with preschoolers’ dietary intake and PA levels. Methods This cross-sectional analysis included 723 preschoolers from 50 randomly selected childcare centres in two Canadian provinces. All data were collected in the fall of 2013 and 2014 and analysed in the fall of 2015. PA was assessed using Actical accelerometers during childcare hours for 5 consecutive days. Children’s dietary intake was measured at lunch on 2 consecutive days using weighed plate waste and digital photography. Childcare educators’ nutrition practices (modelling, nutrition education, satiety recognition, verbal encouragement and not using food as rewards) and PA practices (informal and formal PA promotion) were assessed by direct observation over the course of 2 days, using the Nutrition and Physical Activity Self-Assessment for Child Care tool. Associations between educators’ practices and preschoolers’ PA and dietary intake were examined using multilevel linear regressions. Results Overall, modelling of healthy eating was positively associated with children’s intake of sugar (β=0.141, 95% CI 0.03 to 0.27), while calorie (β=−0.456, 95% CI −1.46 to –0.02) and fibre intake (β=−0.066, 95% CI −0.12 to –0.01) were negatively associated with providing nutrition education. Not using food as rewards was also negatively associated with fat intake (β=−0.144, 95% CI −0.52 to –0.002). None of the educators’ PA practices were associated with children’s participation in PA. Conclusions Modelling healthy eating, providing nutrition education and not using food as rewards are associated with children’s dietary intake at lunch in childcare centres, highlighting the role that educators play in shaping preschoolers’ eating behaviours. Although PA

  13. Is Childhood Socioeconomic Status Independently Associated with Adult BMI after Accounting for Adult and Neighborhood Socioeconomic Status?

    PubMed Central

    2017-01-01

    Childhood socioeconomic status (SES) is inversely associated with adult weight in high income countries. Whether the influence of childhood SES on adult weight is best described using a critical period model or an accumulation of risk model is not yet settled. This research tests whether childhood SES is associated with adult BMI and likelihood of obesity independent of adult socioeconomic status and neighborhood characteristics. Data on individual childhood and adult characteristics come from the Health and Retirement Study (N = 13,545). Data on neighborhood characteristics come from the 2000 Decennial Census and American Community Survey (2005–2009). In the fully adjusted models, perceived financial hardship before the age of sixteen and having a father who was unemployed are associated with higher BMI among males and, among females, paternal education remains associated with adult BMI. However, childhood SES is not associated with likelihood of obesity after fully adjusting for adult SES and neighborhood characteristics, suggesting that the direct effects of early childhood SES on BMI are small relative to the other factors associated with obesity in adulthood.

    The aim of this study was to identify the preference of Indonesian medical students to work in rural areas, to enroll in the (PTT; which means 'temporary employment') program, and to identify factors that influence their choice of a preferred future practice area. Under the PTT program, doctors are obliged to work as temporary staff on a contract basis for a certain period in a rural area of Indonesia. The study design was cross-sectional and a total sampling method was used. The subjects were year 4 and 5 medical students from the Faculty of Medicine at Universitas Indonesia and had already been exposed to clinical practice rotations within their education program. Students rated the importance of 21 factors influencing their future workplace preference using a questionnaire with a five-point Likert scale. A total of 310 students (83.3%) responded to the questionnaire. The authors found that 27 out of 310 (8.71%) subjects wanted to work in rural areas, while 128 out of 264 (48.5%) students who chose other than rural areas wanted to enroll in the PTT program. A previous experience of living in rural areas seemed to be the only factor favouring students' choice to have future practice in rural areas (adjusted odds ratio (OR) 3.20, 95% confidence interval (CI) 1.27-8.08, =0.01). Factors that influenced respondents to say they didn't intend to practice rurally were the influence of spouse (adjusted OR 0.38, 95%CI 0.16-0.89, =0.03), and the opportunities for career advancement (adjusted OR 0.28, 95%CI 0.11-0.73, =0.009). The choice of enrollment in the PTT program was positively associated with opportunity for an academic career (adjusted OR 2.39, 95%CI 1.27-4.50, =0.007) and negatively associated with proximity to family/friends (adjusted OR 0.38, 95%CI 0.22-0.65, 0.001). Only 8.7% of the students were interested in rural areas for their future practice location. Multiple factors were associated with students' interest to choose a career in rural areas later, after

    To determine whether altruism as reason for participation in research is independently associated with adherence to a medical regimen in a clinical trial. Participants were 475 participants in the Women's Estrogen for Stroke Trial. Before randomization to estrogen or placebo, all women were questioned about reason for participation and baseline features that may contribute to adherence. Adherence was defined as completion of at least 80% of expected pill intake during the trial. Women who reported at least one altruistic reason for participation were more likely to be college educated, have a higher level of social support, and a better functional status. They were also more likely to be adherent to their study medication {155 of 212 (73%) vs. 158 of 253 (62.5%), P < .01}. On stratified analysis and multivariable regression, the relationship between altruism as reason for participation and adherence was independent of other sociodemographic, psychosocial, and clinical features (relative risk 1.17, Confidence interval 1.03-1.32). Altruism may explain a small portion of the variation in adherence among research participants. This relationship may have implications for recruitment of participants in clinical research. The possible contribution of altruism to the relationship between adherence and outcomes in clinical trials is worthy of further investigation.

    Sedentary behavior is a main risk factor for cardiovascular disease and mortality. To investigate the association between sedentary behavior and metabolic and cardiovascular risk factors. We assessed 322 participants aged between 18 to 65 years. Physical activity and sedentary behavior were measured with accelerometers (Actigraph®). Body mass index (BMI), waist circumference, percentage of body fat, diet and blood markers (glucose, lipid profile, insulin and HOMA-IR) were measured with standardized protocols. Thirty four percent of participants were physically inactive and spent on average 8.7 h/day on sedentary activities. Per one hour increase in sedentary behavior there were significant adverse changes in glucose (4.79 mg/dl), insulin (2.73 pmol/l), HOMA-IR (0.75), BMI (0.69 kg/m²), waist circumference (1.95 cm), fat mass (1.03%), total cholesterol (9.73 mg/dl), HDL-cholesterol (-3.50 mg/dl), LDL-cholesterol (10.7 mg/dl) and triglycerides (12.4 mg/dl). These findings were independent of main confounding factors including total physical activity, dietary factors, BMI and socio-demographics. The detrimental effect of sedentary behaviors on cardiometabolic and obesity-related traits is independent of physical activity levels. Therefore, reducing sedentary time should be targeted in the population apart from increasing their physical activity levels.

    Innovations in health care call for fresh approaches to continuing nursing education that support lateral relationships, teamwork, and collaboration. To foster this transformation, we devised the following education principles: Everyone teaches, everyone learns; embrace probability; information is dynamic; and trust professionals to practice professionally. These principles guided the development of seven independent, practice-specific, evidence-based continuing nursing education programs totaling 21.5 contact hours for casual-status nurses who practiced as childbirth educators. The programs were popular, promoted teamwork, and increased communication about evidence-based practice.

    Self-medication which is the act of obtaining and using one or more medicines without medical supervision is a common practice among pregnant women. Unless proper caution is taken, it may result in maternal and fetal adverse outcomes. In Ethiopia, information on self-medication practice during pregnancy is scanty. Hence, this study aimed to assess self-medication practice and associated factors among pregnant women in government health centers in Addis Ababa. An institution-based mixed study design using a sequential explanatory approach was employed among 617 pregnant women and nine key informants in Addis Ababa from May 8, 2017, to June 30, 2017. Multi-stage sampling technique was used to select study participants, and purposive sampling technique was used to select the key informants. The quantitative data were collected using a structured interview questionnaire and analyzed using Statistical Product and Service Solutions (SPSS) version 23.0 whereas semi-structured questionnaire was used for in-depth interviews. Binary logistic regression was used for quantitative data analysis, and thematic analysis method was used for qualitative data. The prevalence of self-medication practice was 26.6%. Previous medication use (Adjusted odds ratio (AOR) = 4.20, 95% CI 2.70-6.53), gestational period (AOR = 0.63, 95% CI 0.41-0.98), education on self-medication (AOR = 0.36, 95% CI 0.21-0.62), previous pregnancy and delivery related problems (AOR = 1.71, 95% CI 1.06-2.76), and knowledge about risk of self-medication (AOR = 0.64, 95% CI 0.42-0.97) were significantly associated with self-medication practice. Lack of attention and priority of program designers, absence of strategies and guidelines; weak screening mechanisms, and regulatory enforcement were cited by the key informants as contributing factors for self-medication practices. Considerable proportion of pregnant women practiced self-medication, including medicines categorized to have high risks

    Previous research has suggested a positive association between testosterone (T) and entrepreneurial behavior in males. However, this evidence was found in a study with a small sample size and has not been replicated. In the present study, we aimed to verify this association using two large, independent, population-based samples of males. We tested the association of T with entrepreneurial behavior, operationalized as self-employment, using data from the Rotterdam Study (N=587) and the Study of Health in Pomerania (N=1697). Total testosterone (TT) and sex hormone-binding globulin (SHBG) were measured in the serum. Free testosterone (FT), non-SHBG-bound T (non-SHBG-T), and the TT/SHBG ratio were calculated and used as measures of bioactive serum T, in addition to TT adjusted for SHBG. Using logistic regression models, we found no significant associations between any of the serum T measures and self-employment in either of the samples. To our knowledge, this is the first large-scale study on the relationship between serum T and entrepreneurial behavior. Copyright © 2013 Elsevier Inc. All rights reserved.

    The high level of stress experienced by nurses leads to moral distress, burnout, and a host of detrimental effects. To support creation of healthy work environments and to design a 2-phase project to enhance nurses' resilience while improving retention and reducing turnover. In phase 1, a cross-sectional survey was used to characterize the experiences of a high-stress nursing cohort. A total of 114 nurses in 6 high-intensity units completed 6 survey tools to assess the nurses' characteristics as the context for burnout and to explore factors involved in burnout, moral distress, and resilience. Statistical analysis was used to determine associations between scale measures and to identify independent variables related to burnout. Moral distress was a significant predictor of all 3 aspects of burnout, and the association between burnout and resilience was strong. Greater resilience protected nurses from emotional exhaustion and contributed to personal accomplishment. Spiritual well-being reduced emotional exhaustion and depersonalization; physical well-being was associated with personal accomplishment. Meaning in patient care and hope were independent predictors of burnout. Higher levels of resilience were associated with increased hope and reduced stress. Resilience scores were relatively flat over years of experience. These findings provide the basis for an experimental intervention in phase 2, which is designed to help participants cultivate strategies and practices for renewal, including mindfulness practices and personal resilience plans. ©2015 American Association of Critical-Care Nurses.

    OBJECTIVE To identify factors associated with oral hygiene practices in adults with systemic sclerosis (SSc) METHODS In this cross-sectional study, 178 dentate adults with SSc received an oral examination which included measurement of oral aperture, assessment of manual dexterity to perform oral hygiene, as well as completion of the Center of Epidemiological Studies Depression (CES-D) Scale, and an oral health-related questionnaire. RESULTS Multivariable logistic regression modeling showed male, minority and high CES-D scores (i.e., clinically significant symptoms of depression) were associated with less likelihood of participants brushing teeth at least twice daily, but the presence of self-reported dry mouth symptoms increased the likelihood of toothbrushing. Having a dental visit in the past 12 months, and use of an adapted flossing or interdental cleaning device were significantly associated with daily dental flossing; however, having difficulty flossing teeth reduced the likelihood of daily flossing. CONCLUSIONS Overall, demographic variables were strongly associated with toothbrushing frequency, whereas, flossing self-efficacy and barriers were strongly associated with dental flossing frequency in adults with SSc. The results suggest that dental health professionals should take mental health into consideration when educating patients with SSc to improve their oral hygiene, and consider making referrals for patients exhibiting suspected clinically significant depressive symptoms to mental health professionals for further evaluation and treatment. In addition, an appropriate adapted flossing or interdental cleaning device should be recommended to increase dental flossing practices in this patient population. PMID:24128049

    We aimed to study the independent associations of sedentary time (ST), moderate-to-vigorous physical activity (MVPA), and objectively measured cardiorespiratory fitness (CRF) with clustered cardio-metabolic risk and its individual components (waist circumference, fasting glucose, HDL-cholesterol, triglycerides and blood pressure). We also investigated whether any associations between MVPA or ST and clustered cardio-metabolic risk were mediated by CRF. MVPA, ST, CRF and individual cardio-metabolic components were measured in a population-based sample of 341 adults (age 53.8 ± 8.9 years; 61% men) between 2012 and 2014. MVPA and ST were measured with the SenseWear pro 3 Armband and CRF was measured with a maximal exercise test. Multiple linear regression models and the product of coefficients method were used to examine independent associations and mediation effects, respectively. Results showed that low MVPA and low CRF were associated with a higher clustered cardio-metabolic risk (β = -0.26 and β = -0.43, both p<0.001, respectively). CRF explained 73% of the variance in the association between MVPA and clustered cardio-metabolic risk and attenuated this association to non-significance. After mutual adjustment for MVPA and ST, CRF was the most important risk factor for a higher clustered cardio-metabolic risk (β = -0.39, p<0.001). In conclusion, because of the mediating role of CRF, lifestyle-interventions need to be feasible yet challenging enough to lead to increases in CRF to improve someone’s cardio-metabolic health.

    Background: Substantial interindividual variability exists in the maximal rate of fat oxidation (MFO) during exercise with potential implications for metabolic health. Although the diet can affect the metabolic response to exercise, the contribution of a self-selected diet to the interindividual variability in the MFO requires further clarification. Objective: We sought to identify whether recent, self-selected dietary intake independently predicts the MFO in healthy men and women. Design: The MFO and maximal oxygen uptake (O2 max) were determined with the use of indirect calorimetry in 305 healthy volunteers [150 men and 155 women; mean ± SD age: 25 ± 6 y; body mass index (BMI; in kg/m2): 23 ± 2]. Dual-energy X-ray absorptiometry was used to assess body composition with the self-reported physical activity level (SRPAL) and dietary intake determined in the 4 d before exercise testing. To minimize potential confounding with typically observed sex-related differences (e.g., body composition), predictor variables were mean-centered by sex. In the analyses, hierarchical multiple linear regressions were used to quantify each variable’s influence on the MFO. Results: The mean absolute MFO was 0.55 ± 0.19 g/min (range: 0.19–1.13 g/min). A total of 44.4% of the interindividual variability in the MFO was explained by the O2 max, sex, and SRPAL with dietary carbohydrate (carbohydrate; negative association with the MFO) and fat intake (positive association) associated with an additional 3.2% of the variance. When expressed relative to fat-free mass (FFM), the MFO was 10.8 ± 3.2 mg · kg FFM−1 · min−1 (range: 3.5–20.7 mg · kg FFM−1 · min−1) with 16.6% of the variability explained by the O2 max, sex, and SRPAL; dietary carbohydrate and fat intakes together explained an additional 2.6% of the variability. Biological sex was an independent determinant of the MFO with women showing a higher MFO [men: 10.3 ± 3.1 mg · kg FFM−1 · min−1 (3.5–19.9 mg

    Mothers' feeding practices are associated with their children's weight status, but little is known about the associations between fathers' feeding practices and children's weight status. Moreover, there is a dearth of research on Latino fathers' feeding practices and children's weight status, even though Latino children suffer some of the highest obesity rates in the U.S. We examined the associations between fathers' feeding practices and child weight status, conditional on mothers' feeding practices, within 174 Mexican American families with children aged 8-10 years. Parents completed the Parental Feeding Practices Questionnaire, which consists of four subscales: positive involvement in child eating, pressure to eat, use of food to control behavior, and restriction of amount of food. To assess child weight status, body mass index (BMI) was calculated and converted to age- and gender-specific percentile scores (BMI z-score). We fit four sets of regression models, one set for each of the four parental feeding practices subscales, with child BMI z-score as the outcome variable. Fathers' pressure to eat (b = -0.20, p = 0.04; 95% CI: -0.39, -0.01) and use of food to control behavior (b = -0.36, p = 0.02; 95% CI: -0.65, -0.07) were associated with lower child BMI z-score, and restriction of amount of food (b = 0.56, p < 0.001; 95% CI: 0.27, 0.84) was associated with higher child BMI z-score, after accounting for mothers' feeding practices. Fathers' positive involvement in child eating was not associated with child BMI z-score. These findings provide empirical evidence that fathers' feeding practices are independently associated with children's weight status, even when mothers' feeding practices are taken into account, and suggest that fathers' feeding practices also matter in regard to children's weight status.

    PubMed Central

    2013-01-01

    Background Job satisfaction and organizational attributes in primary care teams are important issues as they affect clinical outcomes and the quality of health care provided. As practice assistants are an integral part of these teams it is important to gain insight into their views on job satisfaction and organizational attributes. The aim of this study was to evaluate the job satisfaction of practice assistants and the organizational attributes within their general practices in Germany and to explore the existence of possible associations. Methods This observational study was based on a job satisfaction survey and measurement of organizational attributes in general practices in the German federal state of Baden-Wuerttemberg. Job satisfaction was measured with the 10-item ‘Warr-Cook-Wall job satisfaction scale’. Organizational attributes were evaluated with the 21-items ‘survey of organizational attributes for primary care’ (SOAPC). Linear regression analyses were performed in which each of SOAPC scales and the overall score of SOAPC was treated as outcome variables. Results 586 practice assistants out of 794 respondents (73.8%) from 234 general practices completed the questionnaire. Practice assistants were mostly satisfied with their colleagues and least of all satisfied with their income and recognition for their work. The regression analysis showed that ‘freedom of working method’ and ‘recognition of work’, the employment status of practice assistants and the mode of practice were almost always significantly associated with each subscale and overall score of SOAPC. Conclusions Job satisfaction is highly associated with different aspects of organizational attributes for primary care (‘communication’, ‘decision-making’ and ‘stress’). Consequently, improved job satisfaction could lead to a better-organized primary care team. This implication should be investigated directly in further intervention studies with a special focus on

    Frailty, a clinical syndrome associated with loss of metabolic reserves, is prevalent among patients who present to vascular surgery clinics for evaluation. The Clinical Frailty Scale (CFS) is a rapid assessment method shown to be highly specific for identifying frail patients. In this study, we sought to evaluate whether the preoperative CFS score could be used to predict loss of independence after major vascular procedures. We identified all patients living independently at home who were prospectively assessed using the CFS before undergoing an elective major vascular surgery procedure (admitted for >24 hours) at an academic medical center between December 2015 and December 2017. Patient- and procedure-level clinical data were obtained from our institutional Vascular Quality Initiative registry database. The composite outcome of discharge to a nonhome location or 30-day mortality was evaluated using bivariate and multivariate regression models. A total of 134 independent patients were assessed using the CFS before they underwent elective open abdominal aortic aneurysm repair (8%), endovascular aneurysm repair (26%), thoracic endovascular aortic repair (6%), suprainguinal bypass (6%), infrainguinal bypass (16%), carotid endarterectomy (19%), or peripheral vascular intervention (20%). Among 39 (29%) individuals categorized as being frail using the CFS, there was no significant difference in age or ASA physical status compared with nonfrail patients. However, frail patients were significantly more likely to need mobility assistance after surgery (62% frail vs 22% nonfrail; P < .01) and to be discharged to a nonhome location (22% frail vs 6% nonfrail; P = .01) or to die within 30 days after surgery (8% frail vs 0% nonfrail; P < .01). Preoperative frailty was associated with a >12-fold higher risk (odds ratio, 12.1; 95% confidence interval, 2.17-66.96; P < .01) of 30-day mortality or loss of independence, independent of the vascular procedure undertaken.

    Background: High intake of fruit juices and soft drinks contributes to excessive weight gain and obesity in children. Furthermore, parenting practices play an important role in the development of children’s dietary habits. The way parents play this role in the development of their children’s choices of beverages is still unclear. Objectives: To study the associations: (1) of both fruit juices and soft drinks consumption with water consumption of children and (2) The associations between parenting practices towards fruit juices and soft drinks and water consumption of children. Design: Cross-sectional data from 6 to 8 year old children from seven European communities (n = 1187) were collected. Associations among fruit juices, soft drinks, the respective parenting practices and the child’s water consumption were assessed by parental questionnaires. Results: The consumption of water was inversely associated with that of soft drinks but not with the consumption of fruit juices. The child’s water intake was favorably influenced when stricter parenting practices towards soft drinks were adopted (e.g., less parental allowance, low home availability and high parental self-efficacy in managing intake). There was less influence observed of parenting practices towards fruit juices. Fruit juices were consumed more often than soft drinks. Conclusions: Low consumption of soft drinks—and not of fruit juices—was associated with high water consumption in children in the current study. Moreover, parenting practices towards both fruit juices and soft drinks were associated with the water intake of the children, irrespective of their socio-economic status. PMID:28561769

    This study is a continuation of a previously published report on the outcome of orthodontic treatment provided in offices representing different modes of practice. The sample consisted of duplicate pretreatment (T1) and posttreatment (T2) dental casts of 348 patients from traditional private orthodontic practices (5 offices, 134 patients), company-owned practices (5 offices, 107 patients), offices associated with practice-management organizations (2 offices, 60 patients), and general dental practices (2 offices, 47 patients). Methods were used to obtain random, representative samples from each office, starting with lists of patients who were treated consecutively with full fixed orthodontic appliances. The dental casts were measured by 2 independent judges who used the unweighted PAR score. Good interjudge agreement was shown on the initial casts, but the agreement was not as strong on the final casts. The measurements showed that treatment outcomes were generally satisfactory, although some significant differences between offices and management modes were shown.

    Circadian misalignment between internal and environmental rhythms dysregulates blood pressure (BP) variability because of disruption of the biological clock, resulting in increased nighttime BP. Although exposure to light-at-night is associated with the circadian misalignment, it remains unclear whether exposure to light-at-night in home settings is associated with nighttime BP. In this cross-sectional analysis of 528 elderly individuals (mean age: 72.8 years), we measured bedroom light intensity at 1-min intervals on two consecutive nights along with ambulatory BP, overnight urinary melatonin excretion and actigraphy. With regard to adjusted mean comparisons using analysis of covariance, the light-at-night group (average: ≥5 lux; n = 109) showed significantly higher nighttime systolic BP (SBP; adjusted mean: 120.8 vs. 116.5 mmHg, p = 0.01) and diastolic BP (70.1 vs. 67.1 mmHg, p < 0.01) compared with the Darker group (average: <5 lux; n = 419) independently of potential confounding factors including overnight urinary melatonin excretion and actigraphic sleep quality. We observed consistent associations between light-at-night and nighttime BP in different cutoff values for light-at-night intensity (i.e. 3 and 10 lux). In conclusion, exposure to light-at-night in home settings is significantly associated with increased nighttime BP in elderly individuals independently of overnight urinary melatonin excretion. A 4.3 mmHg increase in nighttime SBP is associated with a 6.1% increase in total mortality, which corresponds to approximately 10 000 annual excess deaths in Japanese elderly population.

    Insights into the effects of energy balance-related parenting practices on children's diet and activity behavior at an early age is warranted to determine which practices should be recommended and to whom. The purpose of this study was to examine child and parent background correlates of energy balance-related parenting practices at age 5, as well as the associations of these practices with children's diet, activity behavior, and body mass index (BMI) development. Questionnaire data originated from the KOALA Birth Cohort Study for ages 5 (N = 2026) and 7 (N = 1819). Linear regression analyses were used to examine the association of child and parent background characteristics with parenting practices (i.e., diet- and activity-related restriction, monitoring and stimulation), and to examine the associations between these parenting practices and children's diet (in terms of energy intake, dietary fiber intake, and added sugar intake) and activity behavior (i.e., physical activity and sedentary time) at age 5, as well as BMI development from age 5 to age 7. Moderation analyses were used to examine whether the associations between the parenting practices and child behavior depended on child characteristics. Several child and parent background characteristics were associated with the parenting practices. Dietary monitoring, stimulation of healthy intake and stimulation of physical activity were associated with desirable energy balance-related behaviors (i.e., dietary intake and/or activity behavior) and desirable BMI development, whereas restriction of sedentary time showed associations with undesirable behaviors and BMI development. Child eating style and weight status, but not child gender or activity style, moderated the associations between parenting practices and behavior. Dietary restriction and monitoring showed weaker, or even undesirable associations for children with a deviant eating style, whereas these practices showed associations with desirable behavior for

    The aim of this study is to examine characteristics of the nursing practice environment associated with lower RN turnover. Identifying characteristics of the practice environment that contribute to lower RN turnover is important for meeting the national quality strategy priority of reducing healthcare costs. Data from 1002 adult care units in 162 National Database of Nursing Quality Indicators participating hospitals were analyzed using multivariate linear regression. The Practice Environment Scale of the Nursing Work Index was used to measure practice environment characteristics. RN turnover was measured at the unit level. Nursing units with higher overall ratings of the nursing practice environment had lower rates of RN turnover. Units with higher RN perceived staffing and resource adequacy experienced significantly lower RN turnover. Unit managers and hospital administrators should consider RN perception of staffing and resource adequacy and the overall practice environment when developing targeted strategies for decreasing RN turnover.

    No standard approach to obtaining informed consent for stroke thrombolysis with tPA (tissue-type plasminogen activator) currently exists. We aimed to assess current nationwide practice patterns of obtaining informed consent for tPA. An online survey was developed and distributed by e-mail to clinicians involved in acute stroke care. Multivariable logistic regression analyses were performed to determine independent factors contributing to always obtaining informed consent for tPA. Among 268 respondents, 36.7% reported always obtaining informed consent and 51.8% reported the informed consent process caused treatment delays. Being an emergency medicine physician (odds ratio, 5.8; 95% confidence interval, 2.9-11.5) and practicing at a nonacademic medical center (odds ratio, 2.1; 95% confidence interval, 1.0-4.3) were independently associated with always requiring informed consent. The most commonly cited cause of delay was waiting for a patient's family to reach consensus about treatment. Most clinicians always or often require informed consent for stroke thrombolysis. Future research should focus on standardizing content and delivery of tPA information to reduce delays. © 2018 American Heart Association, Inc.

    Both traditional group practices and IPAs have felt the impact of changes brought about by managed care. Group practices need to ensure that their financial reporting and cost-accounting methods capture information that is key to decision making. An independent assessment of financial procedures helps identify any outstanding issues and maintain financial well-being. This assessment should be conducted at least quarterly so that potential problems can be resolved, income opportunities explored, and cost-saving measures adopted in a timely manner.

    The violation of certain Bell inequalities allows for device-independent information processing secure against nonsignaling eavesdroppers. However, this only holds for the Bell network, in which two or more agents perform local measurements on a single shared source of entanglement. To overcome the practical constraints that entangled systems can only be transmitted over relatively short distances, large-scale multisource networks have been employed. Do there exist analogs of Bell inequalities for such networks, whose violation is a resource for device independence? In this Letter, the violation of recently derived polynomial Bell inequalities will be shown to allow for device independence on multisource networks, secure against nonsignaling eavesdroppers.

General community of FPs and GPs who spent most of their clinical time in office settings. Demographic characteristics and scope of practice score (SPS), which was the number of 12 selected medical services provided by office-based FPs and GPs. The multivariable model explained 35.1% of the variation in the SPS among participants. Geographic factors of provincial division and whether or not the population served was rural explained 30.5% of the variation in the SPS. Male physician sex, younger physician age, being in group practice, greater access to hospital beds, less access to specialists, main practice setting of an academic teaching unit, mixed method physician payment, additional structured postresidency training, and greater number of different types of allied health professionals in the main practice setting were also associated with higher SPSs. Geographic factors were the strongest determinants of scope of practice; physician-related factors, availability of health care resources to the main practice setting, and practice organization factors were weaker determinants. It is important to understand how and why geographic factors influence scope of practice, and whether a broad scope of practice independent of population needs benefits the population. This study supports primary care renewal efforts that use mixed payment systems, incorporate allied health care professionals into family and general practices, and foster group practices.

    The Greenberger-Horne-Zeilinger (GHZ) entanglement, originally introduced to uncover the extreme violation of local realism against quantum mechanics, is an important resource for multiparty quantum communication tasks. But the low intensity and fragility of the GHZ entanglement source in current conditions have made the practical applications of these multiparty tasks an experimental challenge. Here we propose a feasible scheme for practically distributing the postselected GHZ entanglement over a distance of more than 100 km for experimentally accessible parameter regimes. Combining the decoy-state and measurement-device-independent protocols for quantum key distribution, we anticipate that our proposal suggests an important avenue for practical multiparty quantum communication.

    Background Parents are likely to be a basic influence on their children's behavior. There is an absence of information about the associations between parents' physical activity and perception of neighborhood environment with children’s independent mobility. The purpose of this study is to examine the contribution of parental physical activity and perception of neighborhood safety to children’s independent mobility. Methods In this cross-sectional study of 354 pupils and their parents, independent mobility, perceptions of neighborhood safety and physical activity were evaluated by questionnaire. Categorical principal components analyses were used to determine the underlying dimensions of both independent mobility and perceptions of neighborhood safety items. Results The strongest predictor of independent mobility was the parental perception of sidewalk and street safety (ß = 0.132). Parent’s physical activity was also a significant predictor. The final model accounted for 13.0% of the variance. Conclusions Parental perception of neighborhood safety and parents’ self reported physical activity might be associated with children’s independent mobility. Further research in this topic is needed to explore this possible association. PMID:23767778

    OBJECTIVE To determine the prevalence of unrecognized lower extremity peripheral arterial disease (PAD) among men and women aged 55 years and older in a general internal medicine (GIM) practice and to identify characteristics and functional performance associated with unrecognized PAD. DESIGN Cross-sectional. SETTING Academic medical center. PARTICIPANTS We identified 143 patients with known PAD from the noninvasive vascular laboratory, and 239 men and women aged 55 and older with no prior PAD history from a GIM practice. Group 1 consisted of patients with PAD consecutively identified from the noninvasive vascular laboratory (n = 143). Group 2 included GIM practice patients found to have an ankle brachial index less than 0.90, consistent with PAD (n = 34). Group 3 consisted of GIM practice patients without PAD (n = 205). MEASUREMENTS AND MAIN RESULTS Leg functioning was assessed with the 6-minute walk, 4-meter walking velocity, and Walking Impairment Questionnaire (WIQ). Of GIM practice patients, 14% had unrecognized PAD. Only 44% of patients in Group 2 had exertional leg symptoms. Distances achieved in the 6-minute walk were 1,130, 1,362, and 1,539 feet for Groups 1, 2, and 3, respectively, adjusting for age, gender, and race (P < .001). The degree of difficulty walking due to leg symptoms as reported on the WIQ was comparable between Groups 2 and 3 and significantly greater in Group 1 than Group 2. In multiple logistic regression analysis including Groups 2 and 3, current cigarette smoking was associated independently with unrecognized PAD (odds ratio [OR], 6.82; 95% confidence interval [95% CI], 1.55 to 29.93). Aspirin therapy was nearly independently associated with absence of PAD (OR, 0.37; 95% CI, 0.12 to 1.12). CONCLUSION Unrecognized PAD is common among men and women aged 55 years and older in GIM practice and is associated with impaired lower extremity functioning. Ankle brachial index screening may be necessary to diagnose unrecognized PAD in a GIM

    Although meditation practice is an important component of many mindfulness-based interventions (MBIs), empirical findings of its effects on psychological functioning are mixed and the mechanisms for the effects remain unclear. Responding with mindfulness (i.e., returning one's attention back to a nonjudgmental, present-oriented awareness) is a fundamental skill practiced in meditations. With repeated meditation practice, this skill is thought to become internalized and be applied to one's daily life. We thus hypothesized that the extent to which individuals responded to daily events with mindfulness would mediate the effects of meditation practice (instance, duration, and adherence to instructions) on psychological well-being. Using a daily diary methodology, we tracked the meditation practice, use of mindful responding during the day, and psychological outcomes (perceived stress, negative and positive affect) of 117 mindfulness-based stress reduction program participants. We found that on days when participants meditated, they responded with greater mindfulness to daily events, which accounted for the beneficial effects of meditating on psychological outcomes. Furthermore, findings suggest that on meditation days, longer and more closely adhered meditation practices were independently associated with increases in mindful responding, which in turn were associated with better psychological outcomes. These results suggest that regular, longer, and more closely adhered meditation practice is an important component of MBIs, in part because it leads to responding more mindfully in daily life, which promotes well-being. © 2017 Wiley Periodicals, Inc.

    Quantum key distribution promises unconditionally secure communications. However, as practical devices tend to deviate from their specifications, the security of some practical systems is no longer valid. In particular, an adversary can exploit imperfect detectors to learn a large part of the secret key, even though the security proof claims otherwise. Recently, a practical approach--measurement-device-independent quantum key distribution--has been proposed to solve this problem. However, so far its security has only been fully proven under the assumption that the legitimate users of the system have unlimited resources. Here we fill this gap and provide a rigorous security proof against general attacks in the finite-key regime. This is obtained by applying large deviation theory, specifically the Chernoff bound, to perform parameter estimation. For the first time we demonstrate the feasibility of long-distance implementations of measurement-device-independent quantum key distribution within a reasonable time frame of signal transmission.

    Objectives To identify compounding practices of independent community pharmacy practitioners in order to make recommendations for the development of curricular objectives for doctor of pharmacy (PharmD) programs. Methods Independent community practitioners were asked about compounding regarding their motivations, common activities, educational exposures, and recommendations for PharmD education. Results Most respondents (69%) accepted compounding as a component of pharmaceutical care and compounded dermatological preparations for local effects, oral solutions, and suspensions at least once a week. Ninety-five percent were exposed to compounding in required pharmacy school courses and most (98%) who identified compounding as a professional service offered in their pharmacy sought additional postgraduate compounding education. Regardless of the extent of compounding emphasis in the practices surveyed, 84% stated that PharmD curricula should include compounding. Conclusions Pharmacy schools should define compounding curricular objectives and develop compounding abilities in a required laboratory course to prepare graduates for pharmaceutical care practice.

    Different maternal psychological states during pregnancy have been associated with wheeze-rhinitis-eczema symptoms in children. However, previous studies were limited and it was unclear whether the type of prenatal psychological state was associated with a particular symptom. We examined the association of maternal depression and anxiety during pregnancy with wheeze-rhinitis-eczema symptoms in infancy. In a longitudinal birth cohort (GUSTO) of 1152 mother-child pairs, wheeze-rhinitis-eczema symptoms in the infants during the first year of life were collected by parental report. Maternal depressive and anxiety symptoms were assessed at 26 weeks of gestation using the Edinburgh Postnatal Depression Scale (EPDS) and State Trait Anxiety Inventory (STAI). Logistic regression analyses were performed with adjustment for potential confounders. An increased risk of wheezing was found in infants of pregnant women with probable depression (EPDS ≥ 15) [odds ratio (OR) = 1.85 (95% confidence interval (CI) 1.10-3.12)], and an increased risk of rhinitis was associated with maternal anxiety [STAI state ≥ 41: OR = 1.42 (95% CI 1.04-1.93); STAI trait ≥ 43: OR = 1.38 (95% CI 1.01-1.88)]. After adjusting for known risk factors for the development of allergic disease, these associations remained significant [EPDS ≥ 15: adjusted OR = 2.09 (95% CI 1.05-4.19); STAI state ≥ 41: adjusted OR = 1.82 (95% CI 1.17-2.82); STAI trait ≥ 43: adjusted OR = 1.70 (95% CI 1.10-2.61)]. However, maternal psychological states were not associated with infantile eczema. This study suggests that there may be an independent effect of prenatal depression on wheezing and anxiety on rhinitis in infancy. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Educational attainment is inversely associated with SBP level in young adulthood. This association has not been studied in an older cohort, and confounding and mediating factors are not well known. The authors hypothesized that higher education is associated with lower levels of SBP independent of many risk factors for hypertension. This prospective observational study included a sample of 764 older community-living participants in the Maintenance of Balance, Independent Living, Intellect and Zest in the Elderly (MOBILIZE) Boston Study. Compared to participants with more than college education, regression analyses showed those with a high school education or less had a SBP value 6.33 mmHg higher [95% confidence interval (CI): 2.55-10.10], and those who had a college education had a SBP value 4.01 mmHg higher (95% CI: 0.77-7.25) independent of many hypothesized confounders and mediators. Results of a path analysis confirmed that higher level of education was associated with lower SBP even after adjustment for hypothesized mediators. Although slightly attenuated by multivariable adjustment for hypertension risk factors, the significant inverse association between educational attainment and SBP was not entirely mediated by these risk factors. These findings indicate that education is inversely associated with SBP in a diverse cohort of community-living older adults, independent of many known or suspected risk factors. This study is the first to report the association between education and SBP in an older sample, representing a population at the highest risk for hypertension-related morbidity and mortality.

    2013-01-04

    Device-independent quantum cryptographic schemes aim to guarantee security to users based only on the output statistics of any components used, and without the need to verify their internal functionality. Since this would protect users against untrustworthy or incompetent manufacturers, sabotage, or device degradation, this idea has excited much interest, and many device-independent schemes have been proposed. Here we identify a critical weakness of device-independent protocols that rely on public communication between secure laboratories. Untrusted devices may record their inputs and outputs and reveal information about them via publicly discussed outputs during later runs. Reusing devices thus compromises the security of a protocol and risks leaking secret data. Possible defenses include securely destroying or isolating used devices. However, these are costly and often impractical. We propose other more practical partial defenses as well as a new protocol structure for device-independent quantum key distribution that aims to achieve composable security in the case of two parties using a small number of devices to repeatedly share keys with each other (and no other party).

    associated with mortality (odds ratio: 1.003, 95% confidence interval: 0.99–1.02, P = 0.613). We conclude that in this cohort of critically ill children, increasing seizure burden was independently associated with a greater probability and magnitude of neurological decline. Our observation that a seizure burden of more than 12 min in a given hour was strongly associated with neurological decline suggests that early antiepileptic drug management is warranted in this population, and identifies this seizure burden threshold as a potential therapeutic target. These findings support the hypothesis that electrographic seizures independently contribute to brain injury and worsen outcome. Our results motivate and inform the design of future studies to determine whether more aggressive seizure treatment can improve outcome. PMID:24595203

    Studies in urban informal settlements show widespread inappropriate infant and young child feeding (IYCF) practices and high rates of food insecurity. This study assessed the association between household food security and IYCF practices in two urban informal settlements in Nairobi, Kenya. The study adopted a longitudinal design that involved a census sample of 1110 children less than 12 months of age and their mothers aged between 12 and 49 years. A questionnaire was used to collect information on: IYCF practices and household food security. Logistic regression was used to determine the association between food insecurity and IYFC practices. The findings showed high household food insecurity; only 19.5% of the households were food secure based on Household Insecurity Access Score. Infant feeding practices were inappropriate: 76% attained minimum meal frequency; 41% of the children attained a minimum dietary diversity; and 27% attained minimum acceptable diet. With the exception of the minimum meal frequency, infants living in food secure households were significantly more likely to achieve appropriate infant feeding practices than those in food insecure households: minimum meal frequency (adjusted odds ratio (AOR)=1.26, P=0.530); minimum dietary diversity (AOR=1.84, P=0.046) and minimum acceptable diet (AOR=2.35, P=0.008). The study adds to the existing body of knowledge by demonstrating an association between household food security and infant feeding practices in low-income settings. The findings imply that interventions aimed at improving infant feeding practices and ultimately nutritional status need to also focus on improving household food security.

  14. Which practice characteristics are associated with the quality of cardiovascular disease prevention in European primary care?

    2013-01-01

    Background Prevention of cardiovascular diseases (CVD) is a major health issue worldwide. Primary care plays an important role in cardiovascular risk management (CVRM). Guidelines and quality of care measures to assess CVRM in primary care practices are available. In this study, we assessed the relationship between structural and organisational practice characteristics and the quality of care provided in individuals at high risk for developing CVD in European primary care. Methods An observational study was conducted in 267 general practices from 9 European countries. Previously developed quality indicators were abstracted from medical records of randomly sampled patients to create a composite quality measure. Practice characteristics were collected by a practice questionnaire and face to face interviews. Data were aggregated using factor analysis to four practice scores representing structural and organisational practice features. A hierarchical multilevel analysis was performed to examine the impact of practice characteristics on quality of CVRM. Results The final sample included 4223 individuals at high risk for developing CVD (28% female) with a mean age of 66.5 years (SD 9.1). Mean indicator achievement was 59.9% with a greater variation between practices than between countries. Predictors at the patient level (age, gender) had no influence on the outcome. At the practice level, the score ‘Preventive Services’ (13 items) was positively associated with clinical performance (r = 1.92; p = 0.0058). Sensitivity analyses resulted in a 5-item score (PrevServ_5) that was also positively associated with the outcome (r = 4.28; p < 0.0001). Conclusions There was a positive association between the quality of CVRM in individuals at high risk for developing CVD and the availability of preventive services related to risk assessment and lifestyle management supported by information technology.

Sensitivity analyses resulted in a 5-item score (PrevServ_5) that was also positively associated with the outcome (r = 4.28; p < 0.0001). There was a positive association between the quality of CVRM in individuals at high risk for developing CVD and the availability of preventive services related to risk assessment and lifestyle management supported by information technology.

  16. Association between parenting practices and children's dietary intake, activity behavior and development of body mass index: the KOALA Birth Cohort Study

    2011-01-01

    Background Insights into the effects of energy balance-related parenting practices on children's diet and activity behavior at an early age is warranted to determine which practices should be recommended and to whom. The purpose of this study was to examine child and parent background correlates of energy balance-related parenting practices at age 5, as well as the associations of these practices with children's diet, activity behavior, and body mass index (BMI) development. Methods Questionnaire data originated from the KOALA Birth Cohort Study for ages 5 (N = 2026) and 7 (N = 1819). Linear regression analyses were used to examine the association of child and parent background characteristics with parenting practices (i.e., diet- and activity-related restriction, monitoring and stimulation), and to examine the associations between these parenting practices and children's diet (in terms of energy intake, dietary fiber intake, and added sugar intake) and activity behavior (i.e., physical activity and sedentary time) at age 5, as well as BMI development from age 5 to age 7. Moderation analyses were used to examine whether the associations between the parenting practices and child behavior depended on child characteristics. Results Several child and parent background characteristics were associated with the parenting practices. Dietary monitoring, stimulation of healthy intake and stimulation of physical activity were associated with desirable energy balance-related behaviors (i.e., dietary intake and/or activity behavior) and desirable BMI development, whereas restriction of sedentary time showed associations with undesirable behaviors and BMI development. Child eating style and weight status, but not child gender or activity style, moderated the associations between parenting practices and behavior. Dietary restriction and monitoring showed weaker, or even undesirable associations for children with a deviant eating style, whereas these practices showed associations

    We explored knowledge, attitudes, and practices associated with the menopause transition particular to women in the multi-ethnic cultural context of Singapore. Fifty-eight Chinese, Malay, and Indian Singaporean women participated in interviews that were audiorecorded, transcribed verbatim, and analyzed using thematic analysis. Women from all three ethnicities described an attitude of acceptance surrounding menopause and the changes associated with it. While they thought it was important to be informed, they did not seek out information about menopause and did not view health professionals as useful sources of information. Management practices were diverse and rarely involved accessing health professionals.

    Sitting behaviours have increased markedly during the last two decades in Chile. However, their associations with health outcomes such as diabetes have not been reported. Therefore, the aim of this study was to investigate the independent association of self-reported sitting time with diabetes-related markers and diabetes prevalence in Chile. This cross-sectional study included participants (aged ≥18 years) from the Chilean National Health Survey 2009-10 (n = 4457). Fasting glucose and haemoglobin A1c (HbA1c) were measured by standardized protocols. The prevalence of type 2 diabetes (T2D) was determined using WHO criteria. Physical activity (PA) and time spent sitting were determined using the Global Physical Activity Questionnaire (GPAQ). The odds ratio for T2D was 1.10 [95% CI: 1.04-1.16, P = 0.002] and 1.08 [1.02-1.14, P = 0.002] per 1 h increase in sitting time in men and women, respectively, independent of age, education, smoking, BMI and total PA. Overall, prevalence of T2D was 10.2 and 17.2% in individuals classified in the lowest and highest categories of sitting time, respectively. No significant associations were found between sitting time and glucose or HbA1c. Sitting time is positively associated with diabetes risk, independent of socio-demographic, obesity and PA levels, in the Chilean population. © The Author 2017.

    In the United Kingdom, pharmacist and nurse independent prescribers are responsible for both the clinical assessment of and prescribing for patients. Prescribing is a complex skill that entails the application of knowledge, skills, and clinical reasoning to arrive at a clinically appropriate decision. Decision-making is influenced and informed by many factors. This study, the first of its kind, explores what factors influence pharmacist and nurse independent prescribers during the process of clinical reasoning. A think-aloud methodology immediately followed by a semi-structured interview was conducted with 11 active nurse and 10 pharmacist independent prescribers working in secondary care. Each participant was presented with validated clinical vignettes for the think-aloud stage. Participants chose the clinical therapeutic areas for the vignettes, based on their self-perceived competencies. Data were audio-recorded, transcribed verbatim, and a constant-comparative approach was used for analysis. Influences on clinical reasoning were broadly categorised into themes: social interaction, intrinsic, and contextual factors. These themes showed that intrinsic, sociocultural, and contextual aspects heavily influenced the clinical reasoning processes of prescribers. For example, prescribers were aware of treatment pathways, but chose to refer patient cases to avoid making the final prescribing decision. Exploration of this behaviour in the interviews revealed that previous experience and attitudes such as confidence and cautiousness associated with responsibility were strong influencers within the decision-making process. In addition, strengthening the professional identity of prescribers could be achieved through collaborative work with interprofessional healthcare teams to orient their professional practice from within the profession. Findings from this study can be used to inform the education, training, and practice of independent prescribers to improve healthcare

    Quantum private queries (QPQ) is an important cryptography protocol aiming to protect both the user’s and database’s privacy when the database is queried privately. Recently, a variety of practical QPQ protocols based on quantum key distribution (QKD) have been proposed. However, for QKD-based QPQ the user’s imperfect detectors can be subjected to some detector- side-channel attacks launched by the dishonest owner of the database. Here, we present a simple example that shows how the detector-blinding attack can damage the security of QKD-based QPQ completely. To remove all the known and unknown detector side channels, we propose a solution of measurement-device-independent QPQ (MDI-QPQ) with single- photon sources. The security of the proposed protocol has been analyzed under some typical attacks. Moreover, we prove that its security is completely loss independent. The results show that practical QPQ will remain the same degree of privacy as before even with seriously uncharacterized detectors.

    Clinical practice guidelines (CPGs) recommend pharmacologic treatments for clinical conditions, and drug structured product labels (SPLs) summarize approved treatment indications. Both resources are intended to promote evidence-based medical practices and guide clinicians' prescribing decisions. However, it is unclear how well CPG recommendations about pharmacologic therapies match SPL indications for recommended drugs. In this study, we perform text mining of CPG summaries to examine drug-disease associations in CPG recommendations and in SPL treatment indications for 15 common chronic conditions. We constructed an initial text corpus of guideline summaries from the National Guideline Clearinghouse (NGC) from a set of manually selected ICD-9 codes for each of the 15 conditions. We obtained 377 relevant guideline summaries and their Major Recommendations section, which excludes guidelines for pediatric patients, pregnant or breastfeeding women, or for medical diagnoses not meeting inclusion criteria. A vocabulary of drug terms was derived from five medical taxonomies. We used named entity recognition, in combination with dictionary-based and ontology-based methods, to identify drug term occurrences in the text corpus and construct drug-disease associations. The ATC (Anatomical Therapeutic Chemical Classification) was utilized to perform drug name and drug class matching to construct the drug-disease associations from CPGs. We then obtained drug-disease associations from SPLs using conditions mentioned in their Indications section in SIDER. The primary outcomes were the frequency of drug-disease associations in CPGs and SPLs, and the frequency of overlap between the two sets of drug-disease associations, with and without using taxonomic information from ATC. Without taxonomic information, we identified 1444 drug-disease associations across CPGs and SPLs for 15 common chronic conditions. Of these, 195 drug-disease associations overlapped between CPGs and SPLs, 917

    Dental hygienists are important members of the oral health care team, providing preventive and prophylactic services and oral health education. However, scope-of-practice parameters in some states limit their ability to provide needed services effectively. In 2001 we developed the Dental Hygiene Professional Practice Index, a numerical tool to measure the state-level professional practice environment for dental hygienists. We used the index to score state-level scopes of practice in all fifty states and the District of Columbia in 2001 and 2014. The mean composite score on the index increased from 43.5 in 2001 to 57.6 in 2014, on a 100-point scale. We also analyzed the association of each state's composite score with an oral health outcome: tooth extractions among the adult population because of decay or disease. After we controlled for individual- and state-level factors, we found in multilevel modeling that more autonomous dental hygienist scope of practice had a positive and significant association with population oral health in both 2001 and 2014.

    In Japan, the maldistribution of physicians between urban and rural areas is increasing. It is important to know the practice location expectations of future physicians. The study was designed as a cross-sectional survey. In 2009-2013, students at a medical school in Japan completed a questionnaire containing 50 items with four-point Likert scales. The students rated the importance of specified individual and occupational aspects. Furthermore, students were asked to state their intention to practice in a rural area. The study sample consisted of 368 students (88.2% response rate). Significant variables that were associated with a positively motivated intent for rural practice were 'presence of a role model' (odds ratio (OR), 5.42; 95% confidence interval (CI), 1.58-18.5), 'admission by school recommendation' (OR, 7.68; 95%CI, 2.14-27.6), 'growing up in a rural area' (OR, 6.16; 95%CI, 1.01-37.6), 'general medicine/family medicine as the first career choice' (OR, 5.88; 95%CI, 2.43-14.2), 'interest in the targeted population' (OR, 16.7; 95%CI, 3.97-69.9), 'memorable experience at a class or clinical rotation' (OR, 3.94; 95%CI, 3.73-416), and 'location of their medical school' (OR, 11.4; 95%CI, 2.79-46.2). The present study suggests that medical schools might recruit students with characteristics associated with intention for rural practice.

    To identify thefactors associated with investment in an office medicine project by French general practice (GP) residents. We conducted a national survey using a web-based self-administered questionnaire and analyzed the data collected by multiple logistic regressions. The dependent variable was "an office medicine project" The explanatory variables were both individual (socio-demographic and linked to training trajectories) and contextual (related to the available training programmes and the regional medical demography). The response rate was 48.5%. Out of the 1,695 residents of the study sample, 315 (18.6%) already had a project to setup an office practice during their third cycle ofmedical studies. The main factors associated with this project were (p < 0.05): to receive strong academic support, to live in a rural or semi-rural area, to work as a GP locum, to perform residency training in the same city as the medical training and to perform residency training in a region with a high percentage of GPs 55years and older. This study showed that a project to setup an office practice was influenced by both individual and contextualfactors. Special attention should be paid to the means and content of training to ensure better supportfor residents, which could make office general practice more attractive.

    The objectives of researchers in this study were to examine acceptance and adherence to mainstream Taiwanese postpartum cultural practices and their association with postpartum depressive symptoms among Chinese and Vietnamese immigrant mothers married to Taiwanese men. While the postpartum cultural practices in China are similar to mainstream Taiwanese practices, those of Vietnam differ from Taiwanese practices. This cross-sectional survey was conducted in Taiwan from October 2007 through March 2008, and included190 immigrant mothers from China and Vietnam who had delivered a child within the past year. Immigrant mothers from China had higher levels of acceptance and adherence to mainstream Taiwanese postpartum cultural practices and a lower rate of postpartum depressive symptoms than immigrant mothers from Vietnam, but the association between adherence to "doing-the-month" practices and postpartum depressive symptoms did not vary significantly between Chinese and Vietnamese mothers. Adherence to these practices was negatively associated with postpartum depressive symptoms among immigrant mothers (OR = 0.93, 95% CI: 0.90-0.96) after adjustment for social support, duration between moving to Taiwan and delivery, and country of origin. Adherence to mainstream postpartum cultural practices was negatively associated with postpartum depressive symptoms for both Chinese and Vietnamese immigrant women married to Taiwanese men.

    During the last decades, the use of active travel modes declined in all age groups. Childhood is a critical time to establish lifelong healthy patterns. To develop effective interventions in this age group, insight in the correlates of health behaviors and the possible mediating factors is necessary. Among children, the role of parents may not be overlooked. Therefore, this study aimed to examine the associations of parental perceptions of neighborhood environmental attributes with active transport and total physical activity in 10-12 year old Belgian boys and girls. Furthermore, this study examined the potential mediating effect of independent mobility on these associations. In the present study, 736 10-12 year old children and their parents from 44 elementary schools in Flanders, Belgium, participated. The children were asked to wear an activity monitor and to fill in a survey questioning demographic factors and the Flemish Physical Activity Questionnaire. The parents filled in a survey concerning demographic factors, the child's level of independent mobility and environmental perceptions (Neighborhood Environmental Walkability Scale). Overall, boys reported more active transport when parents perceived more land use mix diversity, shorter distances to school, good land use mix access, higher residential density and less pleasing neighborhood aesthetics. Higher total physical activity levels were reported when parents perceived shorter distances to school and availability of walking/cycling infrastructure. None of the associations was mediated by independent mobility in boys. Girls reported more active transport when parents perceived higher residential density, more land use mix diversity, shorter distances to school, good land use mix access, available walking/cycling infrastructure and convenient recreational facilities. Girls reported higher total physical activity levels when parents perceived high residential density, good land use mix access, well

    Background Recent laboratory studies have shown that acute alcohol intoxication selectively and effectively dampens aversive responding to an uncertain threat. An emerging hypothesis is that individuals who exhibit heightened reactivity to an uncertain threat may be especially motivated to use alcohol to dampen their distress, setting the stage for negative reinforcement processes to drive excessive alcohol use. However, no study to date has directly examined whether current problematic drinkers exhibit heightened reactivity to an uncertain threat as would be expected. Methods The present study was therefore designed to examine the association between current problematic alcohol use and reactivity to an uncertain threat during sobriety in two, independent samples. In Study 1 (n = 221) and Study 2 (n = 74), adult participants completed the same well-validated threat-of-shock task which separately probes responses to temporally predictable and unpredictable threat. Startle potentiation was measured as an index of aversive responding. Problematic alcohol use was defined as number of binge episodes within the past 30 days in Study 1 and total scores on a self-report measure of hazardous drinking in Study 2. Results As hypothesized, across both studies greater levels of problematic drinking were associated with greater startle potentiation to an unpredictable threat. In Study 2, hazardous drinking scores were also positively associated with startle potentiation to predictable threat. Conclusions The findings are notably consistent with the notion that heightened reactivity to an uncertain threat is an important individual difference factor associated with the onset and/or maintenance of problematic drinking behaviors and may therefore be a novel prevention and intervention target.

    To assess the knowledge, attitude, and practice regarding cervical cancer screening among Kuwaiti women. A total of 300 married Kuwaiti women were randomly selected from those who visited the clinics irrespective of reason(s) for the visit. A structured questionnaire covering sociodemographic characteristics, knowledge, attitude, and practice related to cervical cancer screening was administered. Of the 300 women, complete information was collected from 281 (93.7%), the knowledge about the test was adequate in 147 (52.3%) women, while 86 (30.6%) had adequate attitude towards the test and only 67 (23.8%) had an adequate practice. The main reason given for not having had a Papanicolaou smear was that it was not suggested by the doctor. Among all the respondents 220 (78.7%) would prefer a female doctor to conduct the test. The level of education was the only significant factor independently associated with inadequate knowledge and attitude towards Papanicolaou smear test (p = 0.006 and p = 0.001, respectively) when adjusted for the effect of other factors in multivariate logistic regression analysis. However, age (p < 0.001), level of education (p = 0.028), and number of years since last visit with a gynaecologist (p = 0.005) were significant factors independently associated with inadequate practice of the test. Our findings showed that a well-designed health education programme on cervical cancer and benefits of screening would increase the awareness among Kuwaiti women. Copyright 2008 S. Karger AG, Basel.

    Numerous studies on the involvement of dopamine receptors in the genetics of alcoholism focused on associations between a polymorphism of the D2 dopamine receptor (DRD2) gene and alcohol dependence. However, the results of these studies are conflicting. Another receptor, the D3 dopamine receptor (DRD3), may be of additional interest since it is specifically located in the limbic area, and in particular in the nucleus accumbens which plays a significant role in the reward process of addiction behavior. We thus tested the association in three independent samples of alcoholic patients, with different origins and various inclusion criteria. No difference in themore » DRD3 gene polymorphism emerged between controls and alcoholic patients, regardless of their origin, inclusion criteria, or presence or absence of the DRD2 TaqI A1-allele. Despite the fact that more information could have been considered and that association studies provide limited information, there is good evidence that this DRD3 polymorphism does not play a major role in the genetic component of alcoholism. 17 refs., 2 tabs.« less

    The aim of this study was to examine the relationships between gluteal adipose tissue fatty acids and sleep quality in obese patients with obstructive sleep apnoea syndrome after controlling for possible confounders. Sixty-three patients with obstructive sleep apnoea syndrome based on overnight attended polysomnography were included. Gluteal adipose tissue fatty acids were analysed by gas chromatography. Anthropometric measurements were carried out. Depressive symptoms were assessed by the Zung Self-rating Depression Scale. Saturated fatty acids were positively related to total sleep time, sleep efficiency and rapid eye movement sleep. Significant positive associations were found between polyunsaturated fatty acids and sleep efficiency and rapid eye movement sleep. Moreover, n-3 fatty acids were positively associated with sleep efficiency, slow wave sleep and rapid eye movement sleep. This study revealed independent associations between certain gluteal adipose tissue fatty acids and sleep quality after controlling for age, gender, obesity, obstructive sleep apnoea syndrome indices and Zung Self-rating Depression Scale scores in patients with moderate to severe obstructive sleep apnoea syndrome. © 2013 European Sleep Research Society.

    Objective China is undergoing dramatic Westernization, hence may be able to provide unique insights into the role of sociocultural factors in disease. The purpose of this exploratory study was two-fold: to describe the prevalence of screening-detected eating disorders and disordered eating in China at the first occasion of assessment in the large-scale China Health and Nutrition Survey (CHNS) and to explore the associations between dietary practices and disordered eating. Regarding the first objective, participants are provincially representative and in subsequent waves will be followed longitudinally. Method CHNS participants were recruited using multistage, cluster random sampling, beginning in 1989. In this study, participants comprised 259 female adolescents (12–17 years) and 979 women (18–35 years) who participated in the CHNS 2009 survey, which is the first CHNS survey to assess disordered eating. Dietary practice-disordered eating associations were investigated with logistic regression adjusting for age, body mass index, and urbanization. Results Of the participants, 6.3% (95% CI: 4.8, 8.2) of adults and 7.8% (95% CI: 5.0, 12.0) of adolescents had a screening-detected eating disorder. Dietary practices had non-significant associations with disordered eating at the general population level, except for protein consumption among women. There was evidence that skipping meals and a high-fat diet may confer risk. Discussion Screening-detected eating disorders in China are lower in prevalence than in developed countries. Dietary practices had fairly limited associations with disordered eating at the general population level; protein consumption, skipping meals, and a high-fat diet are candidate dietary practice exposures for disordered eating.

    A mixed methods qualitative survey investigated stakeholder responses to the proposal to develop an independently defined, audited and certifiable set of benchmark standards for responsible food marketing. Its purpose was to inform the policy planning and development process. A majority of respondents were supportive of the proposal. A majority also viewed the engagement and collaboration of a broad base of stakeholders in its planning and development as potentially beneficial. Positive responses were associated with views that policy controls can and should be extended to include all form of marketing, that obesity and non-communicable diseases prevention and control was a shared responsibility and an urgent policy priority and prior experience of independent standardisation as a policy lever for good practice. Strong policy leadership, demonstrable utilisation of the evidence base in its development and deployment and a conceptually clear communications plan were identified as priority targets for future policy planning. Future research priorities include generating more evidence on the feasibility of developing an effective community of practice and theory of change, the strengths and limitations of these and developing an evidence-based step-wise communications strategy.

    Active management of third stage of labor played a great role to prevent child birth related hemorrhage. However, maternal morbidity and mortality related to hemorrhage is high due to lack of knowledge and skill of obstetric care providers 'on active management of third stage of labor. Our study was aimed to assess knowledge, practice and associated factors of obstetric care providers (Midwives, Nurses and Health officers) on active management of third stage of labor in Sidama Zone, South Ethiopia. An institution based cross sectional study design was conducted from December 1-30 /2015 among midwives, nurses and health officers. Simple random sampling technique was used to get the total of 528 participants. Data entry was done using EPI Info 3.5.1 and exported to SPSS version 20.0 software package for analysis. The presence of association between independent and dependent variables was assessed using odds ratio with 97% confidence interval by applying logistic regression model. Of the 528 obstetric care providers 37.7% and 32.8% were knowledgeable and skilled to manage third stage of labor respectively. After controlling for possible confounding factors, the result showed that pre/in service training, being midwife and graduation year were found to be the major predictors of proper active management of third stage of labor. The knowledge and practice of obstetric care providers towards active management of third stage of labor can be improved with appropriate interventions like in-service trainings. This study also clearly showed that the level of knowledge and practice of obstetric care providers to wards active management of third stage of labor needs immediate attention of Universities and health science colleges better to revise their obstetrics course contents, health institutions and zonal health bureau should arrange trainings for their obstetrics care providers to enhance skill.

Data were collected in two cross-sectional mail surveys conducted in independent random samples of GPs in Montreal, the first in 1998, and the second in 2000. Respondents included 653 GPs (71% of 916 eligible). All indicators of smoking cessation counseling practices were more favorable among female GPs. Higher proportions of female GPs had received training (28% vs. 17%, p=0.002), and were aware of mailed print educational materials related to cessation counseling (81% vs. 57%, p<0.0001). Training among male GPs was associated with higher scores for ascertainment of smoking status (odds ratio (OR) (95% confidence interval)=1.69 (0.97, 2.96)), provision of advice (OR=2.20 (1.23, 3.95)), and provision of adjunct support (OR=2.86 (1.58, 5.16)). Training was not associated with counseling practices among female GPs. Female GPs may not benefit from formal cessation counseling training to the same extent as male GPs, possibly because they read and integrate the content of (easily available) print educational materials into their clinical practice to a greater extent than male GPs. The gender-specific impact of print educational material and formal training on cessation counseling should be evaluated among GPs.

    The importance of encoding strategies for associative recall is well established, but there have been no studies of aging and intraindividual variability (IAV) in strategy use during extended practice. We observed strategy use and cued-recall test performance over 101 days of practice in 101 younger adults (M = 25.6 years) and 103 older adults (M = 71.3 years) sandwiched by a pretest and posttest battery including an associative recall test. Each practice session included 2 lists of 12 number-noun paired-associate (PA) items (e.g., 23-DOGS), presented for brief exposures titrated to maintain below-ceiling performance throughout practice. Participants reported strategy use (e.g., rote repetition, imagery) after each test. Substantial IAV in strategy use was detected that was coupled with performance; lists studied with normatively effective strategies (e.g., imagery) generated higher PA recall than lists studied with less effective strategies (e.g., rote repetition). In comparison to younger adults, older adults' practice (a) relied more on repetition and less on effective strategies, (b) showed lower levels of IAV in effective strategy use, and (c) had lower within-person strategy-recall coupling, especially late in practice. Individual differences in pretest-posttest gains in PA recall were predicted by average level of effective strategy use in young adults but by strategy-recall coupling in older adults. Results are consistent with the hypothesis that experiencing variability in strategic outcomes during practice helps hone the effectiveness of strategic encoding behavior, and that older adults' reduced degree of pretest-posttest gains is influenced by lower likelihood of using and optimizing effective strategies through practice.

    Authorities recommend that schools provide a variety of opportunities for students to obtain physical activity (PA) before, during, and after school. This study assessed the prevalence of several school PA practices-including measures of quantity and quality of physical education (PE)-in elementary schools and examined the associations of PA practices with school resources (PE staffing, training, and facilities). Surveys were obtained from respondents in nationally representative samples of elementary schools from 2009-2010 to 2011-2012 (1,831 schools). Few schools (20.8%) provided students with PE class every day, but most (76.3%) had an appropriate PE student-to-teacher ratio ( ≤ 25:1). Many schools (74.0%) offered 20 min of recess daily, but fewer than half offered organized opportunities for PA before or after school (e.g., sports). After controlling for demographics and school size, having a full-time PE teacher and requiring PE teachers to obtain PE-related continuing education (CE) were associated with PE practices such as offering ≥ 150 min of PE per week (for 3rd-grade students) and testing PE knowledge, skills, and fitness. Required CE was also associated with a higher likelihood of offering PA during the school day (i.e., activity breaks and PA outside of PE class) and before or after the school day (i.e., afterschool PA programs). Few schools offer a broad array of PA programming. However, PE staffing and CE are positively associated with many PA practices including those outside of PE, possibly indicating that PE staff serve a crucial role in promoting a whole-school PA-supportive environment.

    Digital signatures play an important role in software distribution, modern communication, and financial transactions, where it is important to detect forgery and tampering. Signatures are a cryptographic technique for validating the authenticity and integrity of messages, software, or digital documents. The security of currently used classical schemes relies on computational assumptions. Quantum digital signatures (QDS), on the other hand, provide information-theoretic security based on the laws of quantum physics. Recent work on QDS Amiri et al., Phys. Rev. A 93, 032325 (2016);, 10.1103/PhysRevA.93.032325 Yin, Fu, and Zeng-Bing, Phys. Rev. A 93, 032316 (2016), 10.1103/PhysRevA.93.032316 shows that such schemes do not require trusted quantum channels and are unconditionally secure against general coherent attacks. However, in practical QDS, just as in quantum key distribution (QKD), the detectors can be subjected to side-channel attacks, which can make the actual implementations insecure. Motivated by the idea of measurement-device-independent quantum key distribution (MDI-QKD), we present a measurement-device-independent QDS (MDI-QDS) scheme, which is secure against all detector side-channel attacks. Based on the rapid development of practical MDI-QKD, our MDI-QDS protocol could also be experimentally implemented, since it requires a similar experimental setup.

    Fillion et al. (2012) recently designed a conceptual framework for professional cancer navigators describing key functions of professional cancer navigation. Building on this framework, this study defines the core areas of practice and associated competencies for professional cancer navigators. The methods used in this study included: literature review, mapping of navigation functions against practice standards and competencies, and validation of this mapping process with professional navigators, their managers and nursing experts and comparison of roles in similar navigation programs. Associated competencies were linked to the three identified core areas of practice, which are: 1) providing information and education, 2) providing emotional and supportive care, and 3) facilitating coordination and continuity of care. Cancer navigators are in a key position to improve patient and family empowerment and continuity of care. This is an important step for advancing the role of oncology nurses in navigator positions and identifying areas for further research.

    We hypothesized that lung injury and rib cage fracture quantification would be associated with adverse outcomes. Consecutive admissions to a trauma center with Injury Severity Score ≥ 9, age 18-75, and blunt trauma. CT scans were reviewed to score rib and sternal fractures and lung infiltrates. Sternum and each anterior, lateral, and posterior rib fracture was scored 1 = non-displaced and 2 = displaced. Rib cage fracture score (RCFS) = total rib fracture score + sternal fracture score + thoracic spine Abbreviated Injury Score (AIS). Four lung regions (right upper/middle, right lower, left upper, and left lower lobes) were each scored for % of infiltrate: 0% = 0; ≤ 20% = 1, ≤ 50% = 2, > 50% = 3; total of 4 scores = lung infiltrate score (LIS). Of 599 patients, 193 (32%) had 854 rib fractures. Rib fracture patients had more abdominal injuries (p < 0.001), hemo/pneumothorax (p < 0.001), lung infiltrates (p < 0.001), thoracic spine injuries (p = 0.001), sternal fractures (p = 0.0028) and death or need for mechanical ventilation ≥ 3 days (Death/Vdays ≥ 3) (p < 0.001). Death/Vdays ≥ 3 was independently associated with RCFS (p < 0.001), LIS (p < 0.001), head AIS (p < 0.001) and abdominal AIS (p < 0.001). Of the 193 rib fracture patients, Glasgow Coma Score 3-12 or head AIS ≥ 2 occurred in 43%. A lung infiltrate or hemo/pneumothorax occurred in 55%. Thoracic spine injury occurred in 23%. RCFS was 6.3 ± 4.4 and Death/Vdays ≥ 3 occurred in 31%. Death/Vdays ≥ 3 rates correlated with RCFS values: 19% for 1-3; 24% for 4-6; 42% for 7-12 and 65% for ≥ 13 (p < 0.001). Death/Vdays ≥ 3 was independently associated with RCFS (p = 0.02), LIS (p = 0.001), head AIS (p < 0.001) and abdominal AIS (p < 0.001). Death/Vdays ≥ 3 association was better for RCFS (p = 0.005) than rib fracture score (p = 0.08) or number of fractured ribs (p = 0.80). Rib fracture patients have increased risk for truncal injuries and adverse outcomes. Adverse outcomes are independently

    To examine critical care nurses' knowledge about the use of the ventilator bundle to prevent ventilator-associated pneumonia. Published reports were reviewed for current evidence on the use of the ventilator bundle to prevent ventilator-associated pneumonia, and education sessions were held to present the findings to 61 nurses in coronary care and surgical intensive care units. Changes in the nurses' knowledge were evaluated by using a 10-item test, given both before and after the sessions. Changes in the nurses' practices related to ventilator-associated pneumonia, including elevation of the head of the bed to 30 degrees to 45 degrees , were observed in 99 intubated patients. After the education sessions, the nurses performed better on 8 of the 10 items tested (P from .03 to <.001). The areas of most significant improvement were elevation of the head of the bed (P < .001), charting of the elevation of the head of the bed (P= .009), oral care (P= .009), checking of the nasogastric tube for residual volume (P = .008), washing of hands before contact with patients (P < .001), and limiting the wearing of rings (P < .001) and nail polish (P = .04). Even after the education sessions, the nurses' compliance with hand-washing recommendations before contact with patients was low, though statistically some improvement was apparent. Contraindications to elevation of the head of the bed did not appear to affect the nurses' practices (P= .38). Education sessions designed to inform nurses about the ventilator bundle and its use to prevent ventilator-associated pneumonia have a significant effect on participants' knowledge and subsequent clinical practice.

    Aims To test whether the TCF7L2 gene was associated with gestational diabetes, whether the association between TCF7L2 and gestational diabetes was independent of HLA-DQB1*0602 and islet cell autoantibodies, as well as maternal age, number of pregnancies, family history of diabetes and the HLA-DQB1 genotypes, and to test whether the distribution of HLA-DQB1 alleles was affected by country of birth. Methods We genotyped the rs7903146, rs12255372 and rs7901695 single nucleotide polymorphisms of the TCF7L2 gene in 826 mothers with gestational diabetes and in 1185 healthy control subjects in the Diabetes Prediction in Skåne Study. The mothers were also typed for HLA-DQB1 genotypes and tested for islet cell autoantibodies against GAD65, insulinoma-associated antigen-2 and insulin. Results The heterozygous genotypes CT, GT and TC of the rs7903146 (T is risk for Type 2 diabetes), rs12255372 (T is risk for Type 2 diabetes) and rs7901695 (C is risk for Type 2 diabetes), respectively, as well as the homozygous genotypes TT, TT and CC of the rs7903146, rs12255372 and rs7901695, respectively, were strongly associated with gestational diabetes (P < 0.0001). These associations remained statistically significant after adjusting for maternal age, number of pregnancies, family history of diabetes and HLA-DQ genotypes and were independent of the presence of islet cell autoantibodies. No interaction was observed between TCF7L2 and HLA-DQB1*0602, which was shown to be negatively associated with gestational diabetes in mothers born in Sweden (P = 0.010). Conclusions The TCF7L2 was associated with susceptibility for gestational diabetes independently of the presence of HLA-DQB1*0602 and islet cell autoantibodies and other factors such as maternal age, number of pregnancies, family history of diabetes and other HLA-DQ genotypes. The HLA-DQB1*0602 was negatively associated with gestational diabetes in mothers born in Sweden. PMID:21672010

    Recently, a quantum key distribution (QKD) scheme based on entanglement swapping, called measurement-device-independent QKD (mdiQKD), was proposed to bypass all measurement side-channel attacks. While mdiQKD is conceptually elegant and offers a supreme level of security, the experimental complexity is challenging for practical systems. For instance, it requires interference between two widely separated independent single-photon sources, and the secret key rates are dependent on detecting two photons—one from each source. Here, we demonstrate a proof-of-principle experiment of a QKD scheme that removes the need for a two-photon system and instead uses the idea of a two-qubit single-photon to significantly simplify themore » implementation and improve the efficiency of mdiQKD in several aspects.« less

    Arterial stiffness can enhance cardiovascular risk by increasing atherogenesis or adverse hemodynamic effects. We examined whether the arterial stiffness markers of aortic pulse wave velocity (PWV) and the augmentation index (AIx) are independently associated with carotid artery intima-media thickness (IMT) and plaque in patients with rheumatoid arthritis (RA). PWV and AIx were determined by brachial oscillometry using the Mobil-O-Graph® system and carotid IMT and plaque by ultrasound in 194 consecutive RA patients without established cardiovascular disease, chronic kidney disease, and diabetes at disease onset. In crude analysis, PWV was associated with IMT (β (95% CI) = 0.04 (0.03 to 0.05), p value < 0.0001) and plaque (OR (95% CI) = 1.69 (1.40 to 2.04), p value < 0.0001). Upon adjustment for the confounders of age, sex, mean blood pressure, body height, and cardiovascular risk factors comprising smoking, the atherogenic index, and diabetes, PWV was not related to IMT (β (95% CI) = 0.01 (-0.02 to 0.04), p value = 0.5) or plaque (OR (95% CI) = 0.99 (0.96 to 1.01), p value = 0.3). AIx was not associated with IMT in crude (β (95% CI) = -0.002 (-0.004 to 0.007), p value = 0.2) and adjusted analyses (β (95% CI) = -0.002 (-0.004 to 0.000), p value = 0.06). AIx was also unrelated to carotid plaque in crude (OR (95% CI) = 1.04 (0.60 to 1.82), p value = 0.9) and adjusted analyses (OR (95% CI) = 0.97 (0.94 to 1.01), p value = 0.1). PWV and AIx are not independently associated with subclinical carotid atherosclerosis in RA.

    Apathy is common in older adults and has been linked to adverse health outcomes. The current study examined whether apathy contributes to problems managing activities of daily living (ADLs) and lower quality of life (QoL) in older adults. Participants included 83 community-dwelling older adults. Apathy was assessed using a composite of the self and family-rating scales from the Frontal Systems Behavioral Scale (FrSBe). A knowledgeable informant completed the Activities of Daily Living Questionnaire (ADLQ), and participants completed the World Health Organization Quality of Life (WHOQol) scale. Nominal logistic regressions controlling for age, anxiety and depression symptoms, chronic medical conditions, and global cognition revealed that higher levels of apathy were significantly associated with a wide range of mild ADL problems. In parallel, a multiple linear regression indicated that greater apathy was significantly associated with lower QoL independent of ADL problems, anxious and depressive symptomology, chronic medical conditions, global cognition and age. Findings suggest that apathy confers an increased risk of problems in the independent management of daily activities and poorer well-being among community-dwelling older adults. Neurobehavioral and pharmacological interventions to improve apathy may have beneficial effects on the daily lives of older adults.

    As epicardial adipose tissue (EAT) is a metabolically active visceral fat, potential interaction between EAT and myocardium is strongly suggested. The aims of this study were to determine whether the amount and regional distribution of EAT are related to the chronicity of atrial fibrillation (AF) and left atrial (LA) remodeling. This study consisted of 40 subjects with paroxysmal AF (PAF) and 40 with persistent AF (PeAF). Eighty subjects with no history of AF were enrolled as controls. Total volume of EAT (EAT(total)), regional thickness of EAT, and LA volume (LAV) were measured by multislice computed tomography. In the AF group, blood samples were drawn from coronary sinus for analysis of inflammatory cytokines including adiponectin. Compared with controls, AF subjects had larger LAV, EAT(total), and the thicknesses of periatrial EAT including interatrial septum (IAS). However, the thicknesses of periventricular EAT were not different between the groups. The PeAF subjects had larger LAV, EAT(total), and periatrial EAT thicknesses, higher levels of inflammatory cytokines, and lower level of adiponectin than did the PAF subjects. Adiponection level was significantly associated with EAT(total) and IAS thickness. Multivariate analysis revealed that EAT(total) (P = 0.004) and IAS thickness (P = 0.016) were independently associated with LAV. EAT(total) and thickness of periatrial EAT were significantly larger in AF subjects compared to those of the matched controls and were closely related to the chronicity of AF. Moreover, EAT(total) and IAS thickness were independently associated with LAV in subjects with AF. © 2011 Wiley Periodicals, Inc.

    It has been reported that skeletal muscle mass and strength are decreased in patients with heart failure (HF), and HF is associated with both reduced exercise capacity and adverse clinical outcomes. Myostatin has been known as a negative regulator of muscle growth, follistatin as the myostatin antagonist, maintaining tissue homeostasis. We thus determined serum myostatin levels in HF patients and whether they are associated with skeletal muscle wasting. Forty one consecutive HF patients (58±15years old, New York Heart Association class I-III) and 30 age-matched healthy subjects as controls (53±8years old) were studied. Serum myostatin levels were significantly lower in HF patients than controls (18.7±7.4 vs. 23.6±5.2ng/mL, P<0.001). Circumference of the thickest part of the right thigh was significantly small (468±72 vs. 559±37mm, P=0.001) and lower extremity muscular strength was lower in patients with HF (129±55 vs. 219±52N×m, P<0.001). Fourteen HF patients (34%) had muscle wasting. By univariate analysis, higher age, higher serum follistatin, and lower serum myostatin were significantly associated with the presence of muscle wasting. By multivariate analysis, serum myostatin levels were independently associated with muscle wasting (OR=0.77, 95% CI [0.58, 0.93], P=0.02). Serum myostatin levels were significantly decreased in HF patients and associated with lower extremity muscle wasting, suggesting that myostatin may be an important factor for maintaining skeletal muscle mass and strength in HF.

    To determine the association of resistance exercise, independent of and combined with aerobic exercise, with the risk of development of metabolic syndrome (MetS). The study cohort included adults (mean ± SD age, 46±9.5 years) who received comprehensive medical examinations at the Cooper Clinic in Dallas, Texas, between January 1, 1987, and December, 31, 2006. Exercise was assessed by self-reported frequency and minutes per week of resistance and aerobic exercise and meeting the US Physical Activity Guidelines (resistance exercise ≥2 d/wk; aerobic exercise ≥500 metabolic equivalent min/wk) at baseline. The incidence of MetS was based on the National Cholesterol Education Program Adult Treatment Panel III criteria. We used Cox regression to generate hazard ratios (HRs) and 95% CIs. Among 7418 participants, 1147 (15%) had development of MetS during a median follow-up of 4 years (maximum, 19 years; minimum, 0.1 year). Meeting the resistance exercise guidelines was associated with a 17% lower risk of MetS (HR, 0.83; 95% CI, 0.73-0.96; P=.009) after adjusting for potential confounders and aerobic exercise. Further, less than 1 hour of weekly resistance exercise was associated with 29% lower risk of development of MetS (HR, 0.71; 95% CI, 0.56-0.89; P=.003) compared with no resistance exercise. However, larger amounts of resistance exercise did not provide further benefits. Individuals meeting both recommended resistance and aerobic exercise guidelines had a 25% lower risk of development of MetS (HR, 0.75; 95% CI, 0.63-0.89; P<.001) compared with meeting neither guideline. Participating in resistance exercise, even less than 1 hour per week, was associated with a lower risk of development of MetS, independent of aerobic exercise. Health professionals should recommend that patients perform resistance exercise along with aerobic exercise to reduce MetS. Copyright © 2017 Mayo Foundation for Medical Education and Research.

    The concept of formative assessment is considered by many to play an important role in enhancing teaching in higher engineering education. In this paper, the concept of the flipped classroom as part of a blended learning curriculum is highlighted as an ideal medium through which formative assessment practices arise. Whilst the advantages of greater interaction between students and lecturers in classes are numerous, there are often clear disadvantages associated with the independent home-study component that complements timetabled sessions in a flipped classroom setting, specifically, the popular method of replacing traditional classroom teaching with video lectures. This leads to a clear lack of assurances that the cited benefits of a flipped classroom approach are echoed in the home-study arena. Over the past three years, the authors have sought to address identified deficiencies in this area of blended learning through the development of database-driven e-learning software with the capability of introducing formative assessment practices to independent home-study. This paper maps out aspects of two specific evolving practices at separate institutions, from which guiding principles of incorporating formative assessment aspects into e-learning software are identified and highlighted in the context of independent home-study as part of a flipped classroom approach.

    To quantify the relation between prenatal famine exposure and adult mortality, taking into account mediating effects of intermediary life conditions. Historical follow-up study. The Dutch famine (Hunger Winter) of 1944-1945 which occurred towards the end of WWII in occupied Netherlands. From 408,015 Dutch male births born 1944-1947, examined for military service at age 18, we selected for follow-up all men born at the time of the famine in six affected cities in the Western Netherlands (n=25,283), and a sample of unexposed time (n=10,667) and place (n=9087) controls. These men were traced and followed for mortality through the national population and death record systems. All-cause mortality between ages 18 and 63 years using Cox proportional hazards models adjusted for intermediary life conditions. An increase in mortality was seen after famine exposure in early gestation (HR 1.12; 95% confidence interval (CI): 1.01-1.24) but not late gestation (HR 1.04; 95% CI: 0.96-1.13). Among intermediary life conditions at age 18 years, educational level was inversely associated with mortality and mortality was elevated in men with fathers with manual versus non-manual occupations (HR 1.08; CI: 1.02-1.16) and in men who were declared unfit for military service (HR 1.44; CI: 1.31-1.58). Associations of intermediate factors with mortality were independent of famine exposure in early life and associations between prenatal famine exposure and adult mortality were independent of social class and education at age 18. Timing of exposure in relation to the stage of pregnancy may be of critical importance for later health outcomes independent of intermediary life conditions. Copyright © 2013 Elsevier Ltd.

    Objective This systematic review aims to evaluate which applicant characteristics available to an otolaryngology selection committee are associated with future performance in residency or practice. Data Sources PubMed, Scopus, ERIC, Health Business, Psychology and Behavioral Sciences Collection, and SocINDEX. Review Methods Study eligibility was performed by 2 independent investigators in accordance with the PRISMA protocol (Preferred Reporting Items for Systematic Reviews and Meta-analyses). Data obtained from each article included research questions, study design, predictors, outcomes, statistical analysis, and results/findings. Study bias was assessed with the Quality in Prognosis Studies tool. Results The initial search identified 439 abstracts. Six articles fulfilled all inclusion and exclusion criteria. All studies were retrospective cohort studies (level 4). Overall, the studies yielded relatively few criteria that correlated with residency success, with generally conflicting results. Most studies were found to have a high risk of bias. Conclusion Previous resident selection research has lacked a theoretical background, thus predisposing this work to inconsistent results and high risk of bias. The included studies provide historical insight into the predictors and criteria (eg, outcomes) previously deemed pertinent by the otolaryngology field. Additional research is needed, possibly integrating aspects of personnel selection, to engage in an evidence-based approach to identify highly qualified candidates who will succeed as future otolaryngologists.

  19. Materialism, status consumption, and consumer independence.

    Materialism influences many people. We focus on two aspects of this influence: reactions to prestige products and to the influence of others. A study of 187 U.S. student consumers shows that materialism is positively related to buying products that confer status. In contrast, materialism is negatively related to consumer independence, an enduring tendency to pay minimal attention to the prescribed norms of other consumers and to make product and brand decisions according to personal preferences. Consuming products for status is also negatively related to consumer independence. Moreover, the association between materialism and consumer independence is completely mediated by consuming for status. Materialism urges consumers to be status conscious so that they follow social norms in purchasing, but seeking status through goods is avoided by less materialistic, independent consumers. A second study (n = 258) also using student consumers confirmed these results.

    Several competency models for training and practice in professional psychology have been proposed in the United States and Canada. Typically, the procedures used in developing and finalizing these models have involved both expert working groups and opportunities for input from interested parties. What has been missing, however, are empirical data to determine the degree to which the model reflects the views of members of the profession as a whole. Using survey data from 466 licensed or registered psychologists (approximately half of whom completed one of two versions of the survey), we examined the degree to which psychologists, both those engaged primarily in practice and those involved in doctoral training, agreed with the competency framework developed by the Association of State and Provincial Psychology Boards' Practice Analysis Task Force (Rodolfa et al., 2013). When distinct time points in training and licensure or registration were considered (i.e., entry-level supervised practice in practicum settings, advanced-level supervised practice during internship, entry level independent practice, and advanced practice), there was limited agreement by survey respondents with the competency framework's proposal about when specific competencies should be attained. In contrast, greater agreement was evident by respondents with the competency framework when the reference point was focused on entry to independent practice (i.e., the competencies necessary for licensure or registration). We discuss the implications of these findings for the development of competency models, as well as for the implementation of competency requirements in both licensure or registration and training contexts. © 2016 Wiley Periodicals, Inc.

    The Shuttle program is one of the most complex engineering activities undertaken anywhere in the world at the present time. The Space Shuttle Independent Assessment Team (SIAT) was chartered in September 1999 by NASA to provide an independent review of the Space Shuttle sub-systems and maintenance practices. During the period from October through December 1999, the team led by Dr. McDonald and comprised of NASA, contractor, and DOD experts reviewed NASA practices, Space Shuffle anomalies, as well as civilian and military aerospace experience. In performing the review, much of a very positive nature was observed by the SIAT, not the least of which was the skill and dedication of the workforce. It is in the unfortunate nature of this type of review that the very positive elements are either not mentioned or dwelt upon. This very complex program has undergone a massive change in structure in the last few years with the transition to a slimmed down, contractor-run operation, the Shuttle Flight Operations Contract (SFOC). This has been accomplished with significant cost savings and without a major incident. This report has identified significant problems that must be addressed to maintain an effective program. These problems are described in each of the Issues, Findings or Observations summarized, and unless noted, appear to be systemic in nature and not confined to any one Shuttle sub-system or element. Specifics are given in the body of the report, along with recommendations to improve the present systems.

    Background Despite considerable research, relationships among gender, alcohol consumption, and health remain controversial, due to potential confounding by health-related attitudes and practices associated with drinking, measurement challenges, and marked gender differences in drinking. We examined gender/alcohol consumption differences in health-related attitudes and practices, and evaluated how these factors affected relationships among gender, alcohol consumption, and health status. Methods A stratified random sample of adult health-plan members completed a mail survey, yielding 7884 respondents (2995 male/4889 female). Using MANCOVAs and adjusting for health-related attitudes, values, and practices, we examined gender differences in relationships between alcohol consumption and health. Results More frequent heavy drinking was associated with worse health-related attitudes and values, worse feelings about visiting the doctor, and worse health-related practices. Relationships between health-related practices and alcohol use differed by gender, and daily or almost daily heavy drinking was associated with significantly lower physical and mental health for women compared to men. Drinking status (lifelong abstainers, former drinkers, and level of regular alcohol consumption) was related to health status and vitality, even after adjusting for health-related attitudes, values, and practices. Relationships did not differ by gender. Former drinkers reported lower physical and mental health status than either lifelong abstainers or current drinkers. Conclusions Drinking status is independently related to physical health, mental health, and vitality, even after controlling for the health-related attitudes, values, and practices expected to confound these relationships. Among current drinkers, women who engage in very frequent heavy drinking have worse physical and mental health than their male counterparts. PMID:23946720

    Objective The association ns between prediabetes and androgens have been rarely reported, especially in Chinese men. We aimed to investigate whether androgens were associated with the prevalence of prediabetes diagnosed with new American Diabetes Association criteria in Chinese men and then to assess which androgen value was the most relevant factor. Methods A total of 2654 men (52.6±13.4 years old) were selected. Serum total testosterone (TT), sex hormone-binding globulin (SHBG) and free testosterone (FT) were measured. Covariance analysis of different androgen values were performed in age subgroups. Multinomial logistic regression was used for the association of TT, SHBG and FT with prediabetes and diabetes, as well as prediabetes in age subgroups. Results According to ADA new criteria, normoglycemia, prediabetes, and diabetes were diagnosed in 1405, 907 and 342 men, respectively. In covariance analysis, SHBG of prediabetes were found lower than that of normoglycemia but higher than that of diabetes (P <0.05). In multinomial logistic regression, serum TT and SHBG were inversely associated with prediabetes and diabetes. While, after full adjustment for age, residence area, economic status, waist circumference, metabolic factors, other two androgen values and HOMA-IR, only the associations of SHBG with prevalence of prediabetes and diabetes persisted statistically significant, especially in the elderly with prediabetes (all P for trend <0.05). Conclusions Serum androgen was inversely associated with prediabetes and diabetes in Chinese men. Low serum SHBG was the most relevant factor for prediabetes and diabetes. Whether it is an independent predictor for incident prediabetes in Chinese men needs further explorations. PMID:27583401

    Fragile X syndrome (FXS) results in intellectual disability (ID) most often caused by silencing of the fragile X mental retardation 1 (FMR1) gene. The resulting absence of fragile X mental retardation protein 1 (FMRP) leads to both pre- and postsynaptic defects, yet whether the pre- and postsynaptic functions of FMRP are independent and have distinct roles in FXS neuropathology remain poorly understood. Here, we demonstrate an independent presynaptic function for FMRP through the study of an ID patient with an FMR1 missense mutation. This mutation, c.413G > A (R138Q), preserves FMRP’s canonical functions in RNA binding and translational regulation, which are traditionally associated with postsynaptic compartments. However, neuronally driven expression of the mutant FMRP is unable to rescue structural defects at the neuromuscular junction in fragile x mental retardation 1 (dfmr1)-deficient Drosophila, suggesting a presynaptic-specific impairment. Furthermore, mutant FMRP loses the ability to rescue presynaptic action potential (AP) broadening in Fmr1 KO mice. The R138Q mutation also disrupts FMRP’s interaction with the large-conductance calcium-activated potassium (BK) channels that modulate AP width. These results reveal a presynaptic- and translation-independent function of FMRP that is linked to a specific subset of FXS phenotypes. PMID:25561520

    TOMM40 SNP rs157580 has been associated with triglyceride levels in genome-wide association studies (GWAS). Chronic caregiving stress moderates the association between triglyceride levels and a nearby SNP rs439401 that is associated with triglyceride levels in GWAS. Here, we report data from two independent Caucasian samples (242 U.S. women and men; 466 Danish men) testing the hypothesis that chronic family stress also moderates the association between rs157580 and triglyceride levels. The interaction of rs157580 and family stress in predicting triglyceride levels was statistically significant in the U.S. sample (p=0.004) and marginally significant (p=0.075) in the Danish sample. The G allele of rs157580 was associated with increased triglyceride levels among family stressed cases in both samples compared with A/A cases, but not among controls. Chronic family stress moderates the association of rs157580 variants with triglyceride levels and should be taken into account for disease risk assessment and potential intervention.

    This study was undertaken to assess any impact on National Board of Medical Examiners (NBME) neurology and psychiatry subject examination scores of changing from an integrated neuropsychiatry clerkship to independent neurology and psychiatry clerkships. NBME psychiatry and neurology subject examinations scores were compared for all 625 students completing the required neuropsychiatry clerkship in academic years 2005-2006 through 2008-2009 with all 650 students completing the independent neurology and psychiatry clerkships in academic years 2009-2010 through 2012-2013. Statistical adjustments were made to ensure comparability across groups and over time. A significant improvement in subject examination scores was associated with the independent clerkships. The independent clerkship model was associated with a modest improvement in NBME subject examination scores. This finding may be attributable to many causes or combination of causes other than curricular design. Curricular planners need to pay attention to the potential impact of course integration on specialty-specific NBME subject examination performance.

    The impact of walking and bicycling on insulin resistance (IR) in women with abdominal obesity is unclear. Pooled analysis of data from a randomized trial on physically active commuting (bicycling + walking vs walking only) in women with abdominal obesity [n = 98; age:47.3 ± 7.6 yrs; waist circumference (WC):103.1 ± 7.8 cm]. Bicycling and walking data were collected during 7 consecutive days by trip meters (Trelock FC-410) and pedometers (Yamax digiwalker SW-200) at baseline, 2, 4, and 6 months. Owing to a skew distribution we analyzed bicycling as a binary dummy variable with a 10 km/week cut-off. Fasting serum insulin and homeostatic model assessment - insulin resistance (HOMA-IR) were assessed at baseline and 6 months, as were body mass index (BMI), WC, and dual x-ray absorptiometry (DXA)-assessed % whole-body fat. Increased bicycling by 10 km/wk was associated with reductions in fasting serum insulin at follow-up independent of age, treatment allocation, baseline phenotype, Δ walking, and Δ % body fat (β = -10.9, P = .042), but not HOMA-IR (β = -2.0, P = .13). Increased walking was not associated with fasting serum insulin (P = .33) or HOMA-IR (P = .44) at follow-up, after adjustment for the same covariates and Δ bicycling. Increased bicycling but not walking was associated with reduced insulin levels at follow-up. Bicycling may be more effective than walking for reducing insulin levels in abdominally obese women.

  9. Community care: the independent sector.

    The independent sector, which consists of the voluntary and private sectors, is a vital element in supporting older people in the community. The voluntary sector, coordinated by the Council for Voluntary Service and the National Council for Voluntary Organisations, provides a variety of services, including practical help, reassurance and companionship, and advice, information, campaigning, and advocacy. The private sector owns all of the nursing homes and most of the residential homes and is gradually becoming more involved with the provision of services to help support older people in their own homes. With this increase in size and importance of the independent sector over recent years, there is now a real need for greater communication between the private, voluntary, and statutory agencies in any one region. In some areas, forums made up of representatives of these various sectors meet to discuss relevant issues and construct local policies, thus allowing a more coordinated approach to the delivery of services.

    Interventions using the “Four Immeasurables Meditations” (FIM) are effective for various outcomes; however, whether increased meditation practice in these interventions leads to better results has not been well investigated. This systematic review included 22 FIM interventions that reported associations between the amount of meditation practice and its outcomes. Despite the heterogeneity in intervention components and outcome variables, there were generally few significant associations between amount of meditation practice and its outcomes. Specifically, only five studies reported that more than half of the calculated results were significant. In comparison with correlations between total amount of practice and overall outcomes, the short-term influence of meditation practice was evaluated in fewer studies; however, it had a better association with outcomes. More studies are required that address the underlying mechanisms that elucidate how meditation practice leads to outcome changes in daily life. In this study, two promising mechanisms with initial evidence were discussed. This review also summarized common methodological issues including a lack of experimental manipulation and inaccurate measuring of meditation practice. PMID:28220101

    In this paper, by combining measurement-device-independent quantum key distribution (MDI-QKD) scheme with entangled photon sources, we present a modified MDI-QKD scheme with pairs of vector vortex(VV) beams, which shows a structure of hybrid entangled entanglement corresponding to intrasystem entanglement and intersystem entanglement. The former entanglement, which is entangled between polarization and orbit angular momentum within each VV beam, is adopted to overcome the polarization misalignment associated with random rotations in quantum key distribution. The latter entanglement, which is entangled between the two VV beams, is used to perform entangled-based MDI-QKD protocol with pair of VV beams to inherit the merit of long distance. The numerical simulations show that our modified scheme can tolerate 97dB with practical detectors. Furthermore, our modified protocol only needs to insert q-plates in practical experiment.

    While studies have documented robust relationships between body image and sexual health outcomes, few studies have looked beyond sexual functioning in women. Here, we hypothesized that more positive body image would be associated with greater sexual liberalism and more positive attitudes toward unconventional sexual practices. An online sample of 151 women and 164 men from the U.S. completed measures of sexual liberalism, attitudes toward unconventional sexual practices, and indices of positive body image (i.e., body appreciation, body acceptance by others, body image flexibility, and body pride), and provided their demographic details. Regression analyses indicated that, once the effects of sexual orientation, relationship status, age, and body mass index had been accounted for, higher body appreciation was significantly associated with greater sexual liberalism in women and men. Furthermore, higher body appreciation and body image flexibility were significantly associated with more positive attitudes toward unconventional sexual practices in women and men. These results may have implications for scholars working from a sex-positive perspective, particularly in terms of understanding the role body image plays in sexual attitudes and behaviors.

    Using data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development and a model-building approach, the authors examined direct and indirect associations between first-grade (G1) classroom-level adversity (CLA), G1 teaching practices, and student (N = 1,073; M = 6.64 years; 49% girls; 82% White) academic skills and executive functioning in G1 and third grades (G3). Teachers reported the prevalence of adversity among their students (e.g., poor home/family life, poor academic/social readiness). Observers rated G1 teaching practices: teachers' classroom management, controlling instruction, and amount of academic instruction (classroom observation system). Children completed literacy and math assessments at 54 months, G1, and G3 (Woodcock Johnson Letter-Word Identification and Applied Problems), and executive functioning at G1 and G3 (Tower of Hanoi). Direct associations emerged between CLA and controlling instruction (positive), classroom management, and academic instruction (both negative). In addition, CLA was related to G1 literacy (but not math) directly and indirectly via classroom management (negatively) and controlling instruction (positively). The addition of G3 outcomes revealed a negative direct longitudinal association between CLA and G3 executive functioning, and indirect associations with G3 literacy and math through G1 teaching practices and literacy. Results support the notion that collective student characteristics influence student outcomes in part through teaching practices and suggest that teachers and students may benefit from the diffusion of high-adversity classroom compositions when possible. Moreover, in high-adversity classrooms teachers and students may benefit from supports targeting classroom management and foundational student competencies.

    Whether Title VII funding enhances physician supply in underserved areas has not clearly been established. To determine the relation between Title VII funding in medical school, residency, or both, and the number of family physicians practicing in rural or low-income communities. A retrospective cross sectional analysis was carried out using the 2000 American Academy of Family Physicians physician database, Title VII funding records, and 1990 U.S. Census data. Included were 9,107 family physicians practicing in 9 nationally representative states in the year 2000. Physicians exposed to Title VII funding through medical school and residency were more likely to have their current practice in low-income communities (11.9% vs 9.9%, P< or =.02) and rural areas (24.5% vs 21.8%, P< or =.02). Physicians were more likely to practice in rural communities if they attended medical schools (24.2% vs 21.4%; P =.009) and residencies (24.0% vs 20.3%; P =.011) after the school or program had at least 5 years of Title VII funding vs before. Similar increases were not observed for practice in low-income communities. In a multivariate analysis, exposure to funding and attending an institution with more years of funding independently increased the odds of practicing in rural or low-income communities. Title VII funding is associated with an increase in the family physician workforce in rural and low-income communities. This effect is temporally related to initiation of funding and independently associated with effect in a multivariate analysis, suggesting a potential causal relationship. Whereas the absolute 2% increase in family physicians in these underserved communities may seem modest, it can represent a substantial increase in access to health care for community members.

    The Institute of Medicine (IOM) recommended in its 2010 report on the future of nursing that advanced practice registered nurses (APRNs) should factor prominently in providing care to the millions of Americans who access healthcare services under the Affordable Care Act (ACA). The IOM also recommended that APRNs practice to the full extent of their education and training.However, many states have laws in place that limit full practice authority for APRNs, specifically NPs, in providing basic health services such as primary care. These laws place restrictions on independent practice and Medicaid and Medicare reimbursement, which prevent nurses from “responding effectively to rapidly changing health care settings and an evolving health care system.” Less than half of the United States has adopted full practice authority licensure and practice laws (see APRN practice authority at a glance). This article discusses how the primary care needs of millions of Americans can be met by granting full practice authority to APRNs nationwide and provides evidence to support the high level of care these practitioners can provide independently.

    Transfusion-associated circulatory overload is characterized by hydrostatic pulmonary edema following blood transfusion. Restrictive transfusion practice may affect the occurrence and severity of transfusion-associated circulatory overload in critically ill patients. We sought to examine contemporary risk factors and outcomes for transfusion-associated circulatory overload. Case-control study. Four tertiary care hospitals. We prospectively enrolled 200 patients with transfusion-associated circulatory overload identified by active surveillance and 405 controls matched by transfusion intensity. None. Among 20,845 transfused patients who received 128,263 blood components from May 2015 until July 2016, transfusion-associated circulatory overload incidence was one case per 100 transfused patients. In addition to cardiovascular comorbidities, multivariable analysis identified the following independent predictors of transfusion-associated circulatory overload: acute kidney injury, emergency surgery, pretransfusion diuretic use, and plasma transfusion-the latter especially in females. Compared with matched controls, transfusion-associated circulatory overload cases were more likely to require mechanical ventilation (71% vs 49%; p < 0.001), experienced longer intensive care and hospital lengths of stay following transfusion, and had higher mortality (21% vs 11%; p = 0.02) even after adjustment for other potentially confounding variables. Despite restrictive transfusion practice, transfusion-associated circulatory overload remains a frequent complication of transfusion and is an independent risk factor for in-hospital morbidity and mortality. In addition to cardiovascular and renal risk factors, plasma transfusion was associated with transfusion-associated circulatory overload after controlling for other covariates. Additional research is needed to examine the benefit of reduced erythrocyte or plasma exposure in patients at high risk for transfusion-associated circulatory

    Article-at-a-Glance Background: Catheter-associated urinary tract infection (CAUTI), a frequent health care–associated infection (HAI), is a costly and common condition resulting in patient discomfort, activity restriction, and hospital discharge delays. The Centers for Medicare & Medicaid Services (CMS) no longer reimburses hospitals for the extra cost of caring for patients who develop CAUTI. The Michigan Health and Hospital Association (MHA) Keystone Center for Patient Safety & Quality has initiated a statewide initiative, MHA Keystone HAI, to help ameliorate the burden of disease associated with indwelling catheterization. In addition, a long-term research project is being conducted to evaluate the current initiative and to identify practical strategies to ensure the effective use of proven infection prevention and patient safety practices. Overview of the Bladder Bundle Initiative in Michigan: The bladder bundle as conceived by MHA Keystone HAI focuses on preventing CAUTI by optimizing the use of urinary catheters with a specific emphasis on continual assessment and catheter removal as soon as possible, especially for patients without a clear indication. Collaboration Between Researchers and State wide Patient Safety Organizations: A synergistic collaboration between patient safety researchers and a statewide patient safety organization is aimed at identifying effective strategies to move evidence from peer-reviewed literature to the bedside. Practical strategies that facilitate implementation of the bundle will be developed and tested using mixed quantitative and qualitative methods. Discussion: Simply disseminating scientific evidence is often ineffective in changing clinical practice. Therefore, learning how to implement these findings is critically important to promoting high-quality care and a safe health care environment. PMID:19769204
