US hospital-based direct access with radiology referral: an administrative case report.
Keil, Aaron; Brown, Suzanne Robben
2015-01-01
Legislative gains in the US allow physical therapists to function in expanded scopes of practice including direct access and referral to specialists. The combination of direct access with privileges to order imaging studies directly offers a desirable practice status for many physical therapists, especially in musculoskeletal focused settings. Although direct access is legal in all US jurisdictions, institutional-based physical therapy settings have not embraced these practices. Barriers cited to implementing direct access with advanced practice are concerns over medical and administrative opposition, institutional policies, provider qualifications and reimbursement. This administrative case report describes the process taken to allow therapists to see patients without a referral and to order diagnostic imaging studies at an academic medical center. Nine-month implementation results show 66 patients seen via direct access with 15% referred for imaging studies. Claims submitted to 20 different insurance providers were reimbursed at 100%. While institutional regulations and reimbursement are reported as barriers to direct access, this report highlights the process one academic medical center used to implement direct access and advanced practice radiology referral by updating policies and procedures, identifying advanced competencies and communicating with necessary stakeholder groups. Favorable reimbursement for services is documented.

Direct access compared with referred physical therapy episodes of care: a systematic review.
Ojha, Heidi A; Snyder, Rachel S; Davenport, Todd E
2014-01-01
Evidence suggests that physical therapy through direct access may help decrease costs and improve patient outcomes compared with physical therapy by physician referral. The purpose of this study was to conduct a systematic review of the literature on patients with musculoskeletal injuries and compare health care costs and patient outcomes in episodes of physical therapy by direct access compared with referred physical therapy. Ovid MEDLINE, CINAHL (EBSCO), Web of Science, and PEDro were searched using terms related to physical therapy and direct access. Included articles were hand searched for additional references. Included studies compared data from physical therapy by direct access with physical therapy by physician referral, studying cost, outcomes, or harm. The studies were appraised using the Centre for Evidence-Based Medicine (CEBM) levels of evidence criteria and assigned a methodological score. Of the 1,501 articles that were screened, 8 articles at levels 3 to 4 on the CEBM scale were included. There were statistically significant and clinically meaningful findings across studies that satisfaction and outcomes were superior, and numbers of physical therapy visits, imaging ordered, medications prescribed, and additional non-physical therapy appointments were less in cohorts receiving physical therapy by direct access compared with referred episodes of care. There was no evidence for harm. There is evidence across level 3 and 4 studies (grade B to C CEBM level of recommendation) that physical therapy by direct access compared with referred episodes of care is associated with improved patient outcomes and decreased costs. Primary limitations were lack of group randomization, potential for selection bias, and limited generalizability. Physical therapy by way of direct access may contain health care costs and promote high-quality health care. Third-party payers should consider paying for physical therapy by direct access to decrease health care costs and incentivize optimal patient outcomes.

Direct access: factors that affect physical therapist practice in the state of Ohio.
McCallum, Christine A; DiAngelis, Tom
2012-05-01
Direct access to physical therapist services is permitted by law in the majority of states and across all practice settings. Ohio enacted such legislation in 2004; however, it was unknown how direct access had affected actual clinical practice. The purpose of this study was to describe physical therapist and physical therapist practice environment factors that affect direct access practice. A 2-phase, mixed-method descriptive study was conducted. In the first phase, focus group interviews with 32 purposively selected physical therapists were completed, which resulted in 8 themes for an electronically distributed questionnaire. In the second phase, survey questionnaires were distributed to physical therapists with an e-mail address on file with the Ohio licensing board. An adjusted return rate of 23% was achieved. Data were analyzed for descriptive statistics. A constant comparative method assessed open-ended questions for common themes and patterns. Thirty-one percent of the respondents reported using direct access in physical therapist practice; however, 80% reported they would practice direct access if provided the opportunity. Physical therapists who practiced direct access were more likely to be in practice 6 years or more and hold advanced degrees beyond the entry level, were American Physical Therapy Association members, and had supportive management and organizational practice policies. The direct access physical therapist practice was generally a locally owned suburban private practice or a school-based clinic that saw approximately 6% to 10% of its patients by direct access. The majority of patients treated were adults with musculoskeletal or neuromuscular impairments. Nonresponse from e-mail may be associated with sample frame bias. Implementation of a direct access physical therapist practice model is evident in Ohio. Factors related to reimbursement and organizational policy appear to impede the process.

Hospital-Based Outpatient Direct Access to Physical Therapist Services: Current Status in Wisconsin.
Boissonnault, William G; Lovely, Karen
2016-11-01
Direct access to physical therapist services is available in all 50 states, with reported benefits including reduced health care costs, enhanced patient satisfaction, and no apparent compromised patient safety. Despite the benefits and legality of direct access, few data exist regarding the degree of model adoption, implementation, and utilization. The purposes of the study were: (1) to investigate the extent of implementation and utilization of direct access to outpatient physical therapist services in Wisconsin hospitals and medical centers, (2) to identify barriers to and facilitators for the provisioning of such services, and (3) to identify potential differences between facilities that do and do not provide direct access services. A descriptive survey was conducted. Eighty-nine survey questionnaires were distributed via email to the directors of rehabilitation services at Wisconsin hospitals and medical centers. The survey investigated facility adoption of the direct access model, challenges to and resources utilized during model implementation, and current barriers affecting model utilization. Forty-seven (52.8%) of the 89 survey questionnaires were completed and returned. Forty-two percent of the survey respondents (20 of 47) reported that their facility offered direct access to physical therapist services, but fewer than 10% of patients were seen via direct access at 95% of the facilities offering such services. The most frequently reported obstacles to model implementation and utilization were lack of health care provider, administrator, and patient knowledge of direct access; its legality in Wisconsin; and physical therapists' differential diagnosis and medical screening abilities. Potential respondent bias and limited generalizability of the results are limitations of the study. These findings apply to hospitals and medical centers located in Wisconsin, not to facilities located in other geographic regions. Respondents representing direct access organizations reported more timely access to physical therapist services, enhanced patient satisfaction, decreased organizational health care costs, and improved efficiency of resource utilization as benefits of model implementation. For organizations without direct access, not being an organizational priority, concerns from referral sources, and concerns that the physician-patient relationship would be negatively affected were noted as obstacles to model adoption. © 2016 American Physical Therapy Association.

Self-Directed Digital Learning: When Do Dental Students Study?
Jackson, Tate H; Zhong, James; Phillips, Ceib; Koroluk, Lorne D
2018-04-01
The Growth and Development (G&D) curriculum at the University of North Carolina at Chapel Hill School of Dentistry uses self-directed web-based learning modules in the place of lectures and includes scheduled self-study times during the 8 am-5 pm school hours. The aim of this study was to use direct observation to evaluate dental students' access patterns with the self-directed, web-based learning modules in relation to planned self-study time allocated across the curriculum, proximity to course examinations, and course performance. Module access for all 80 students in the DDS Class of 2014 was recorded for date and time across the four G&D courses. Module access data were used to determine likelihood of usage during scheduled time and frequency of usage in three timeframes: >7, 3 to 7, and 0 to 2 days before the final exam. The results showed a statistically significant difference in the likelihood of module access during scheduled time across the curriculum (p<0.0001). Among the students, 64% accessed modules at least once during scheduled time in G&D1, but only 10%, 19%, and 18% in G&D2, G&D3, and G&D4, respectively. For all courses, the proportion of module accesses was significantly higher 0-2 days before an exam compared to the other two timeframes. Module access also differed significantly within each timeframe across all four courses (p<0.001). There was no association between module access and course performance. In this non-traditional, non-lecture, self-directed curriculum, students rarely accessed learning modules during syllabus-budgeted self-study time and accessed modules more frequently as course exams approached.

International policy advocates for direct access, but the extent to which it exists worldwide was unknown. The purpose of this study was to map the presence of direct access to physical therapy services in the member organizations of the World Confederation for Physical Therapy (WCPT) in the context of physical therapist practice and health systems. A 2-stage, mixed-method, descriptive study was conducted. A purposive sample of member organizations of WCPT in Europe was used to refine the survey instrument, followed by an online survey sent to all WCPT member organizations. Data were analyzed using descriptive statistics, and content analysis was used to analyze open-ended responses to identify themes. A response rate of 68% (72/106) was achieved. Direct access to physical therapy was reported by 58% of the respondents, with greater prevalence in private settings. Organizations reported that professional (entry-level) education equipped physical therapists for direct access in 69% of the countries. National physical therapy associations (89%) and the public (84%) were thought to be in support of direct access, with less support perceived from policy makers (35%) and physicians (16%). Physical therapists' ability to assess, diagnose, and refer patients on to specialists was more prevalent in the presence of direct access. The findings may not be representative of the Asia Western Pacific (AWP) region, where there was a lower response rate. Professional legislation, the medical profession, politicians, and policy makers are perceived to act as both barriers to and facilitators of direct access. Evidence for clinical effectiveness and cost-effectiveness and examples of good practice are seen as vital resources that could be shared internationally, and professional leadership has an important role to play in facilitating change and advocacy.

Cellulase digestibility of pretreated biomass is limited by cellulose accessibility.
Jeoh, Tina; Ishizawa, Claudia I; Davis, Mark F; Himmel, Michael E; Adney, William S; Johnson, David K
2007-09-01
Attempts to correlate the physical and chemical properties of biomass to its susceptibility to enzyme digestion are often inconclusive or contradictory depending on variables such as the type of substrate, the pretreatment conditions and measurement techniques. In this study, we present a direct method for measuring the key factors governing cellulose digestibility in a biomass sample by directly probing cellulase binding and activity using a purified cellobiohydrolase (Cel7A) from Trichoderma reesei. Fluorescence-labeled T. reesei Cel7A was used to assay pretreated corn stover samples and pure cellulosic substrates to identify barriers to accessibility by this important component of cellulase preparations. The results showed cellulose conversion improved when T. reesei Cel7A bound in higher concentrations, indicating that the enzyme had greater access to the substrate. Factors such as the pretreatment severity, drying after pretreatment, and cellulose crystallinity were found to directly impact enzyme accessibility. This study provides direct evidence to support the notion that the best pretreatment schemes for rendering biomass more digestible to cellobiohydrolase enzymes are those that improve access to the cellulose in biomass cell walls, as well as those able to reduce the crystallinity of cell wall cellulose.

Neighbourhood access to open spaces and the physical activity of residents: a national study.
Witten, Karen; Hiscock, Rosemary; Pearce, Jamie; Blakely, Tony
2008-09-01
Increasing population levels of physical activity is high on the health agenda in many countries. There is some evidence that neighbourhood access to public open space can increase physical activity by providing easier and more direct access to opportunities for exercise. This national study examines the relationship between travel time access to parks and beaches, BMI and physical activity in New Zealand neighbourhoods. Access to parks and beaches, measured in minutes taken by a car, was calculated for 38,350 neighbourhoods nationally using Geographic Information Systems. Multilevel regression analyses were used to establish the significance of access to these recreational amenities as a predictor of BMI, and levels of physical activity and sedentary behaviour in the 12,529 participants, living in 1178 neighbourhoods, of the New Zealand Health Survey 2002/3. Neighbourhood access to parks was not associated with BMI, sedentary behaviour or physical activity, after controlling for individual-level socio-economic variables, and neighbourhood-level deprivation and urban/rural status. There was some evidence of a relationship between beach access and BMI and physical activity in the expected direction. This study found little evidence of an association between locational access to open spaces and physical activity.

In response to long waiting lists and problems with access to primary care physiotherapy, several Primary Care Trusts (PCTs) (now Clinical Commissioning Groups CCGs) developed physiotherapy-led telephone assessment and treatment services. The Medical Research Council (MRC) funded PhysioDirect trial was a randomised control trial (RCT) in four PCTs, with a total of 2252 patients that compared this approach with usual physiotherapy care. This nested qualitative study aimed to explore the acceptability of the PhysioDirect telephone assessment and advice service to patients with musculoskeletal conditions. We conducted 57 semi-structured interviews with adults from 4 PCTs who were referred from general practice to physiotherapy with musculoskeletal conditions and were participating in the PhysioDirect trial. The Framework method was used to analyse the qualitative data. The PhysioDirect service was largely viewed as acceptable although some saw it as a first step to subsequent face-to-face physiotherapy. Most participants found accessing the PhysioDirect service straightforward and smooth, and they valued the faster access to physiotherapy advice offered by the telephone service. Participants generally viewed both the PhysioDirect service and the physiotherapists providing the service as helpful. Participants' preferences and priorities for treatment defined the acceptable features of PhysioDirect but the acceptable features were traded off against less acceptable features. Some participants felt that the PhysioDirect service was impersonal and impaired the development of a good relationship with their physiotherapist, which made the service feel remote and less valuable. The PhysioDirect service was broadly acceptable to participants since it provided faster access to physiotherapy advice for their musculoskeletal conditions. Participants felt that it is best placed as one method of accessing physiotherapy services, in addition to, rather than as a replacement for, more traditional face-to-face physiotherapy assessment and treatment.

Federally qualified health centers (FQHCs) offer primary and preventive healthcare, including cancer screening, for the nation’s most vulnerable population. The purpose of this study was to explore the relationship between access to FQHCs and cancer mortality-to-incidence ratios (MIRs). One-way analysis of variance was conducted to compare the mean MIRs for breast, cervical, prostate, and colorectal cancers for each U.S. county for 2006–2010 by access to FQHCs (direct access, in-county FQHC; indirect access, adjacent-county FQHC; no access, no FQHC either in the county or in adjacent counties). ArcMap 10.1 software was used to map cancer MIRs and FQHC access levels. The mean MIRs for breast, cervical, and prostate cancer differed significantly across FQHC access levels (p < 0.05). In urban and healthcare professional shortage areas, mean MIRs decreased as FQHC access increased. A trend of lower breast and prostate cancer MIRs in direct access to FQHCs was found for all racial groups, but this trend was significant for whites only. States with a large proportion of rural and medically underserved areas had high mean MIRs, with correspondingly more direct FQHC access. Expanding FQHCs to more underserved areas and concentrations of disparity populations may have an important role in reducing cancer morbidity and mortality, as well as racial-ethnic disparities, in the United States.

Dental hygienists expand access to oral care in the United States. Many Americans have access to oral health care in traditional dental offices however millions of Americans have unmet dental needs. For decades dental hygienists have provided opportunities for un-served and under-served Americans to receive preventive services in a variety of alternate delivery sites, and referral to licensed dentists for dental care needs. Publications, state practice acts, state public health departments, the American Dental Hygienists' Association, and personal interviews of dental hygiene practitioners were accessed for information and statistical data. Dental hygienists in 36 states can legally provide direct access care. Dental hygienists are providing preventive services in a variety of settings to previously un-served and under-served Americans, with referral to dentists for dental needs. Dental hygienists have provided direct access to care in the United States for decades. The exact number of direct access providers in the United States is unknown. Limited research and anecdotal information demonstrate that direct access care has facilitated alternate entry points into the oral health systems for thousands of previously un-served and underserved Americans. Older adults, persons with special needs, children in schools, pregnant women, minority populations, rural populations, and others have benefited from the availability of many services provided by direct access dental hygienists. Legislatures and private groups are becoming increasingly aware of the impact that direct access has made on the delivery of oral health care. Many factors continue to drive the growth of direct access care. Additional research is needed to accumulate qualitative and quantitative outcome data related to direct access care provided by dental hygienists and other mid level providers of oral health services.

Background Patients are increasingly using the Internet to communicate with health care providers and access general and personal health information. Missed test results have been identified as a critical safety issue with studies showing up to 75% of tests for emergency department (ED) patients not being followed-up. One strategy that could reduce the likelihood of important results being missed is for ED patients to have direct access to their test results. This could be achieved electronically using a patient portal tied to the hospital’s electronic medical record or accessed from the relevant laboratory information system. Patients have expressed interest in accessing test results directly, but there have been no reported studies on emergency physicians’ opinions. Objective The aim was to explore emergency physicians’ current practices of test result notification and attitudes to direct patient notification of clinically significant abnormal and normal test results. Methods A cross-sectional survey was self-administered by senior emergency physicians (site A: n=50; site B: n=39) at 2 large public metropolitan teaching hospitals in Australia. Outcome measures included current practices for notification of results (timing, methods, and responsibilities) and concerns with direct notification. Results The response rate was 69% (61/89). More than half of the emergency physicians (54%, 33/61) were uncomfortable with patients receiving direct notification of abnormal test results. A similar proportion (57%, 35/61) was comfortable with direct notification of normal test results. Physicians were more likely to agree with direct notification of normal test results if they believed it would reduce their workload (OR 5.72, 95% CI 1.14-39.76). Main concerns were that patients could be anxious (85%, 52/61), confused (92%, 56/61), and lacking in the necessary expertise to interpret their results (90%, 55/61). Conclusions Although patients’ direct access to test results could serve as a safety net reducing the likelihood of abnormal results being missed, emergency physicians’ concerns need further exploration: which results are suitable and the timing and method of direct release to patients. Methods of access, including secure Web-based patient portals with drill-down facilities providing test descriptions and result interpretations, or laboratories sending results directly to patients, need evaluation to ensure patient safety is not compromised and the processes fit with ED clinician and laboratory work practices and patient needs.

Limited school drinking water access for youth
Kenney, Erica L.; Gortmaker, Steven L.; Cohen, Juliana F.W.; Rimm, Eric B.; Cradock, Angie L.
2016-01-01
PURPOSE Providing children and youth with safe, adequate drinking water access during school is essential for health. This study utilized objectively measured data to investigate the extent to which schools provide drinking water access that meets state and federal policies. METHODS We visited 59 middle and high schools in Massachusetts during spring 2012. Trained research assistants documented the type, location, and working condition of all water access points throughout each school building using a standard protocol. School food service directors (FSDs) completed surveys reporting water access in cafeterias. We evaluated school compliance with state plumbing codes and federal regulations and compared FSD self-reports of water access with direct observation; data were analyzed in 2014. RESULTS On average, each school had 1.5 (SD: 0.6) water sources per 75 students; 82% (SD: 20) were functioning, and fewer (70%) were both clean and functioning. Less than half of the schools met the federal Healthy Hunger Free Kids Act requirement for free water access during lunch; 18 schools (31%) provided bottled water for purchase but no free water. Slightly over half (59%) met the Massachusetts state plumbing code. FSDs overestimated free drinking water access compared to direct observation (96% FSD-reported versus 48% observed, kappa=0.07, p=0.17). CONCLUSIONS School drinking water access may be limited. In this study, many schools did not meet state or federal policies for minimum student drinking water access. School administrative staff may not accurately report water access. Public health action is needed to increase school drinking water access. IMPLICATIONS AND CONTRIBUTIONS Adolescents’ water consumption is lower than recommended. In a sample of Massachusetts middle and high schools, about half did not meet federal and state minimum drinking water access policies. Direct observation may improve assessments of drinking water access and could be integrated into routine school food service monitoring protocols. PMID:27235376

Cement-retained implant-supported restorations have advantages over screw-retained restorations but are difficult to retrieve. Identifying the approximate location of the screw access hole (SAH) may reduce damage to the prosthesis. The purpose of this in vitro study was to evaluate the ability of cone beam computed tomography (CBCT) imaging to determine the location and direction of SAHs in cement-retained implant prostheses. Five clear acrylic resin casts were made based on a mandibular model. Several implant osteotomies (n=30) were created on the models with surgical burs, and crowns were made using the standard laboratory method with a transfer coping and the closed tray impression technique. CBCT images from the acrylic resin casts were evaluated by a maxillofacial radiologist who was blind to the locations and angles of the osteotomies. The locations of the access holes were determined on multiplanar reconstruction images and transferred to the clinical crown surface as defined points. Based on cross-sectional images, the predicted angle of the access hole was provided to a prosthodontist who was requested to pierce the crown at the proposed location in the specified direction. If the location and/or direction of the access hole were found, the process was considered successful, as the crown could then be removed from the implant abutment through the SAH. The success rate in the detection of the location and direction of the SAH was calculated, and chi-square and Fisher exact tests were applied for data analysis (α=.05). According to the results of this study, the success rate of CBCT to define the location of SAHs was 83.3% and 80% to determine the direction. No significant differences were found among the different dental groups in determination of the location (P=.79) or the direction (P=.53) of the SAHs. Most of the failures in determining the location and direction of the access hole in the buccolingual and mesiodistal directions were in the buccal and mesial locations of the SAH. The success rate of using CBCT to determine the location of SAHs in straight abutments was 100%. A significant difference was found between angled and straight abutments (P=.042). Using CBCT could help determine the direction and location of SAHs in clinical situations. Copyright © 2017 Editorial Council for the Journal of Prosthetic Dentistry. Published by Elsevier Inc.

Direct superficial femoral artery (SFA) antegrade puncture is a valid alternative to common femoral artery (CFA) access for peripheral vascular interventions. Data investigating vascular closure device (VCD) hemostasis of distant SFA 6F access are limited. We aimed to investigate the safety and effectiveness of the Starclose SE® VCD for hemostasis, following direct 6F antegrade SFA access distal to the femoral head. This prospective, single-center study included patients who were not suitable for CFA puncture and were scheduled to undergo peripheral endovascular interventions using direct antegrade SFA 6F access, at least 2 cm below the inferior edge of femoral head. Hemostasis was obtained with the Starclose SE® VCD (Abbott Laboratories). Primary endpoints were successful hemostasis rate and periprocedural (30-day) major complication rate. Secondary endpoint was the rate of minor complications. Clinical and Doppler ultrasound follow-up was performed at discharge and at one month. Between September 2014 and August 2015, a total of 30 patients (21 male; 70.0%) with a mean body mass index of 41.2 kg/m2 were enrolled. Mean age was 72±9 years (range, 67-88 years). Most patients suffered from critical limb ischemia (87.1%) and diabetes (61.3%). Calcifications were present in eight cases (26.6%). Reason for direct SFA puncture was obesity (100%). Successful hemostasis was achieved in 100% of the cases. No major complications were noted after one-month follow-up. Minor complications included two <5 cm hematomas (6.6%) not necessitating treatment. In this prospective study, Starclose SE® VCD was safe and effective for hemostasis of antegrade direct SFA puncture. Uncomplicated hemostasis was achieved even in cases of puncturing 2 to 7 cm below the inferior edge of the femoral head.

Atopic dermatitis (AD) is a chronic disease requiring regular follow-up. To increase access to dermatological care, online management of AD is being studied. However, a critical knowledge gap exists in determining AD patients' quality of life in direct-to-patient online models. In this study, we examined quality of life in AD patients managed through a direct-access online model. We randomized 156 patients to receiving care through a direct-access online platform or in person. Patients were seen for six visits over 12 months. At each visit, the patients completed Dermatology Life Quality Index/Children's Dermatology Life Quality Index (DLQI/CDLQI), and Short Form (SF-12). Between baseline and 12 months, the mean (standard deviation, SD) within-group difference in DLQI score in the online group was 4.1 (±2.3); for the in-person group, the within-group difference was 4.8 (±2.7). The mean (SD) within-group difference in CDLQI score in the online group was 4.7 (±2.8); for the in-person group, the within-group difference was 4.9 (±3.1). The mean (SD) within-group difference in physical component score (PCS) and mental component score (MCS) SF-12 scores in the online group was 6.5 (±3.8) and 8.6 (±4.3); for the in-person group, it was 6.8 (±3.2) and 9.1(±3.8), respectively. The difference in the change in DLQI, CDLQI, SF-12 PCS, and SF-12 MCS scores between the two groups was 0.72 (95% confidence interval [90% CI], -0.97 to 2.41), 0.23 (90% CI, -2.21 to 2.67), 0.34 (90% CI, -1.16 to 1.84), and 0.51 (90% CI, -1.11 to 2.13), respectively. All differences were contained within their equivalence margins. Adult and pediatric AD patients receiving direct-access online care had equivalent quality of life outcomes as those see in person. The direct-access online model has the potential to increase access to care for patients with chronic skin diseases.

Question: Can a mobile optimized subject guide facilitate medical student access to mobile point-of-care tools? Setting: The guide was created at a library at a research-intensive university with six teaching hospital sites. Objectives: The team created a guide facilitating medical student access to point-of-care tools directly on mobile devices to provide information allowing them to access and set up resources with little assistance. Methods: Two librarians designed a mobile optimized subject guide for medicine and conducted a survey to test its usefulness. Results: Web analytics and survey results demonstrate that the guide is used and the students are satisfied. Conclusion: The library will continue to use the subject guide as its primary means of supporting mobile devices. It remains to be seen if the mobile guide facilitates access for those who do not need assistance and want direct access to the resources. Internet access in the hospitals remains an issue.

The cost of accessing infant HIV medications and health services in Uganda.
Bergmann, Julie N; Wanyenze, Rhoda K; Stockman, Jamila K
2017-11-01
Patient costs are a critical barrier to the elimination of mother to child HIV transmission. Despite the Ugandan government providing free public HIV services, infant antiretroviral (ARV) prophylaxis coverage remains low (25%). To understand costs mothers incur in accessing ARV prophylaxis for their infants, we conducted a mixed methods study to quantify and identify their direct costs. We used cross-sectional survey data and focus group discussions from 49 HIV-positive mothers in Uganda. Means and standard deviations were calculated for the direct costs (e.g., transportation, caretaker, services/medications) involved in accessing infant HIV services. The direct cost of attending HIV clinic visits averaged $3.71 (SD = $3.52). Focus group discussions identified two costs hindering access to infant HIV services: transportation costs and informal service charges. All participants reported significant costs associated with accessing infant HIV services - the equivalent of 2-3 days' income. To address transportation costs, community and home care models should be explored. Additionally, stricter policies and oversight should be implemented to prevent informal HIV service charges.

The Ecological Status (ES; sensu the Water Framework Directive) of intertidal benthic communities within six oyster trestle cultivation sites was found to be negatively impacted along the access routes to trestles in a 2013 study. All cultivation sites occur within Natura 2000 sites. The current study revisited four of the 2013 cultivation sites in February 2014 one month after the storm activity of winter 2013/14 to test if the compaction effect along access routes persisted after the storms. Three levels of the fixed factor treatment were sampled; immediately below the trestles, along the access route and 300m away from any anthropogenic activity. The compaction effect at the Access treatment persisted in spite of the major storm activity. The current study showed the IQI to be effective for assessing the impacts of aquaculture and highlights the IQI as a tool for monitoring Conservation Status of intertidal communities under the Habitats Directive.

Reducing young people's access to cigarettes is a key element of smoking prevention policies. This article explores how young people source cigarettes following the increase in the UK minimum age of sale from 16 to 18 years. Semi-structured individual, paired and triadic interviews with 60 disadvantaged young people aged between 12 and 17. Participants were recruited from clubs and voluntary organizations offering advice and support to disadvantaged young people. Most participants said they sourced cigarettes from shops, but understandings of "buying cigarettes from shops" included using intermediaries for proxy purchases. Access from social sources was contingent on reciprocation, and blackmarket sources were avoided. The distinction between potential and actual sources reflected participants concerns about their presentation of self. Those who bought cigarettes directly from shops accrued status and power in negotiating social hierarchies. Participants therefore highlighted their smoking related competencies, that is, ability to secure regular retail access to tobacco, while downplaying the significant difficulties they experienced. The presentational dimension of youth cigarette access highlights a need for caution in associating self-reported changes in young people's cigarette sources straightforwardly with access policies. The conflation of direct retail purchases with proxy purchases, and the interrelationship between commercial and social cigarette sources also raises issues for interpreting data on "usual" cigarette sources from national surveys. Findings suggest that some young people may still be both reliant on making retail cigarette purchases following the increase in the age of sale in the United Kingdom, and experiencing significant difficulties making these. This study highlights the self-presentational dimension of youth cigarette access in a particular community context, and the important distinction between the apparent range of sources available and their social acceptability in young people's social networks. Young smokers tended to conflate direct retail purchases with proxy purchases, raising issues for interpreting survey data on "usual" cigarette source. The presentational dimension of youth cigarette access also highlights a need for caution in associating self-reported changes in young people's cigarette sources with access policies. Despite participants' stated easy access, few were able to buy cigarettes directly, underscoring the effectiveness of youth access policies. © The Author 2016.

Study Design Retrospective study. Background Alternative models of care that allow patients to choose direct access to physical therapy have shown promise in terms of cost reduction for neck and back pain. However, real-world exploration within the US health care system is notably limited. Objectives To compare total claims paid and patient outcomes for patients with neck and back pain who received physical therapy intervention via direct access versus medical referral. Methods Data were accessed for patients seeking care for neck or back pain (n = 603) between 2012 and 2014, who chose to begin care either through traditional medical referral or direct access to a physical therapy- led spine management program. All patients received a standardized, pragmatic physical therapy approach, with patient-reported measures of pain and disability assessed before and after treatment. Patient demographics and outcomes data were obtained from the medical center patient registry and combined with total claims paid calculated for the year after the index claim. Linear mixed-effects modeling was used to analyze group differences in pain and disability, visits/time, and annualized costs. Results Patients who chose to enter care via the direct-access physical therapy-led spine management program displayed significantly lower total costs (mean difference, $1543; 95% confidence interval: $51, $3028; P = .04) than those who chose traditional medical referral. Patients in both groups showed clinically important improvements in pain and disability, which were similar between groups (P>.05). Conclusion The initial patient choice to begin care with a physical therapist for back or neck pain resulted in lower cost of care over the next year, while resulting in similar improvements in patient outcomes at discharge from physical therapy. These findings add to the emerging literature suggesting that patients' choice to access physical therapy through direct access may be associated with lower health care expenditures for patients with neck and back pain. Level of Evidence Economic and decision analyses, level 4. J Orthop Sports Phys Ther 2018;48(2):63-71. Epub 26 Oct 2017. doi:10.2519/jospt.2018.7423.

Limited School Drinking Water Access for Youth.
Kenney, Erica L; Gortmaker, Steven L; Cohen, Juliana F W; Rimm, Eric B; Cradock, Angie L
2016-07-01
Providing children and youth with safe, adequate drinking water access during school is essential for health. This study used objectively measured data to investigate the extent to which schools provide drinking water access that meets state and federal policies. We visited 59 middle and high schools in Massachusetts during spring 2012. Trained research assistants documented the type, location, and working condition of all water access points throughout each school building using a standard protocol. School food service directors (FSDs) completed surveys reporting water access in cafeterias. We evaluated school compliance with state plumbing codes and federal regulations and compared FSD self-reports of water access with direct observation; data were analyzed in 2014. On average, each school had 1.5 (standard deviation: .6) water sources per 75 students; 82% (standard deviation: 20) were functioning and fewer (70%) were both clean and functioning. Less than half of the schools met the federal Healthy Hunger-Free Kids Act requirement for free water access during lunch; 18 schools (31%) provided bottled water for purchase but no free water. Slightly over half (59%) met the Massachusetts state plumbing code. FSDs overestimated free drinking water access compared to direct observation (96% FSD reported vs. 48% observed, kappa = .07, p = .17). School drinking water access may be limited. In this study, many schools did not meet state or federal policies for minimum student drinking water access. School administrative staff may not accurately report water access. Public health action is needed to increase school drinking water access. Copyright © 2016 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.

Photographs provide critical retrieval cues for personal remembering, but few studies have considered this phenomenon at the collective level. In this research, we examined the psychological consequences of visual attention to the presence (or absence) of racially charged retrieval cues within American racial segregation photographs. We hypothesised that attention to racial retrieval cues embedded in historical photographs would increase social justice concept accessibility. In Study 1, we recorded gaze patterns with an eye-tracker among participants viewing images that contained racial retrieval cues or were digitally manipulated to remove them. In Study 2, we manipulated participants' gaze behaviour by either directing visual attention toward racial retrieval cues, away from racial retrieval cues, or directing attention within photographs where racial retrieval cues were missing. Across Studies 1 and 2, visual attention to racial retrieval cues in photographs documenting historical segregation predicted social justice concept accessibility.

Introduction Around 17% of general practitioner (GP) consultations are for musculoskeletal conditions, which will rise as the population ages. Patient direct access to physiotherapy provides one solution, yet adoption in the National Health Service (NHS) has been slow. Setting A pilot, pragmatic, non-inferiority, cluster randomised controlled trial (RCT) in general practice and physiotherapy services in the UK. Objectives Investigate feasibility of a main RCT. Participants Adult patients registered in participating practices and consulting with a musculoskeletal problem. Interventions 4 general practices (clusters) randomised to provide GP-led care as usual or the addition of a patient direct access to physiotherapy pathway. Outcomes Process outcomes and exploratory analyses of clinical and cost outcomes. Data collection Participant-level data were collected via questionnaires at identification, 2, 6 and 12 months and through medical records. Blinding The study statistician and research nurses were blinded to practice allocation. Results Of 2696 patients invited to complete study questionnaires, 978 participated (intervention group n=425, control arm n=553) and were analysed. Participant recruitment was completed in 6 months. Follow-up rates were 78% (6 months) and 71% (12 months). No evidence of selection bias was observed. The direct access pathway was used by 90% of patients in intervention practices needing physiotherapy. Some increase in referrals to physiotherapy occurred from one practice, although waiting times for physiotherapy did not increase (28 days before, 26 days after introduction of direct access). No safety issues were identified. Clinical and cost outcomes were similar in both groups. Exploratory estimates of between group effect (using 36-item Short Form Health Survey (SF-36) Physical Component Summary (PCS)) at 6 months was −0.28 (95% CI −1.35 to 0.79) and at 12 months 0.12 (95% CI −1.27 to 1.51). Conclusions A full RCT is feasible and will provide trial evidence about the clinical and cost-effectiveness of patient direct access to physiotherapy. Trial registration number ISRCTN23378642.

Bermudagrass (Cynodon dactylon L.) is a prominent warm-season turf and forage grass species with multiple applications. In most C. dactylon cultivars and accessions, erect-growing stems (shoot) and prostrate-growing stems (stolon) often coexist. These two types of stems are both formed through tillering but grow in two directions with different tiller angles. Elucidating the mechanism of tiller angle regulation in bermudagrass could provide important clues to breed cultivars with different plant architectural features for diverse usage. In this study, we compared the stem internode transcriptome of two bermudagrass wild accessions with extremely different tiller angles and stem growth directions. A total of 2088 and 12,141 unigenes were preferentially expressed in prostrate-growing wild accession C792 and erect-growing wild accession C793, respectively. Kyoto Encyclopedia of Genes and Genomes (KEGG) Orthology-based Annotation System (KOBAS) analyses further indicated that light- and gravity-responsive genes were enriched in accession C792, whereas lignin synthesis-related genes were enriched in accession C793, which well explains the difference in lignification of vascular bundles and mechanical tissues in the two accessions. These results not only expand our understanding of the genetic control of tiller angle and stem growth direction in bermudagrass but also provide insight for future molecular breeding of C. dactylon and other turfgrass species with different plant architectures.

Foot and Ankle Fellowship Websites: An Assessment of Accessibility and Quality.
Hinds, Richard M; Danna, Natalie R; Capo, John T; Mroczek, Kenneth J
2017-08-01
The Internet has been reported to be the first informational resource for many fellowship applicants. The objective of this study was to assess the accessibility of orthopaedic foot and ankle fellowship websites and to evaluate the quality of information provided via program websites. The American Orthopaedic Foot and Ankle Society (AOFAS) and the Fellowship and Residency Electronic Interactive Database (FREIDA) fellowship databases were accessed to generate a comprehensive list of orthopaedic foot and ankle fellowship programs. The databases were reviewed for links to fellowship program websites and compared with program websites accessed from a Google search. Accessible fellowship websites were then analyzed for the quality of recruitment and educational content pertinent to fellowship applicants. Forty-seven orthopaedic foot and ankle fellowship programs were identified. The AOFAS database featured direct links to 7 (15%) fellowship websites with the independent Google search yielding direct links to 29 (62%) websites. No direct website links were provided in the FREIDA database. Thirty-six accessible websites were analyzed for content. Program websites featured a mean 44% (range = 5% to 75%) of the total assessed content. The most commonly presented recruitment and educational content was a program description (94%) and description of fellow operative experience (83%), respectively. There is substantial variability in the accessibility and quality of orthopaedic foot and ankle fellowship websites. Recognition of deficits in accessibility and content quality may assist foot and ankle fellowships in improving program information online. Level IV.

In the current work, we aimed to study the processing of phonological, orthographical, and lexical information of Chinese characters in sentence contexts, as well as to provide further evidence for psychological models. In the experiment, we designed sentences with expected, homophonic, orthographically similar, synonymous, and control characters as endings, respectively. The results indicated that P200 might be related to the early extraction of phonological information. Moreover, it might also represent immediate semantic and orthographic lexical access. This suggested that there might be a dual-route in cognitive processing, where the direct access route and the phonologically mediated access route both exist and interact with each other. The increased N400 under the control condition suggested that both phonological and orthographical information would influence semantic integration in Chinese sentence comprehension. The two positive peaks of the late positive shift might represent the semantic monitoring, and orthographical retrieval and reanalysis processing, respectively. Under the orthographically similar condition, orthographical retrieval and reanalysis processing was more difficult in comparison with the other conditions, which suggested that there might be direct access from orthography to semantic representation in cognitive processing. In conclusion, it was shown that the direct access hypothesis or the dual-route hypothesis could better explain cognitive processing in the brain. Copyright © 2010 Elsevier B.V. All rights reserved.

Objectives This study sought to evaluate feasibility of nonsurgical transthoracic catheter-based left ventricular (LV) access and closure. Background Implanting large devices, such as mitral or aortic valve prostheses, into the heart requires surgical exposure and repair. Reliable percutaneous direct transthoracic LV access and closure would allow new nonsurgical therapeutic procedures. Methods Percutaneous direct LV access was performed in 19 swine using real-time magnetic resonance imaging (MRI) and an “active” MRI needle antenna to deliver an 18-F introducer sheath. The LV access ports were closed percutaneously using a commercial ventricular septal defect occluder and an “active” MRI delivery cable for enhanced visibility. We used “permissive pericardial tamponade” (temporary fluid instillation to separate the 2 pericardial layers) to avoid pericardial entrapment by the epicardial disk. Techniques were developed in 8 animals, and 11 more were followed up to 3 months by MRI and histopathology. Results Imaging guidance allowed 18-F sheath access and closure with appropriate positioning of the occluder inside the transmyocardial tunnel. Of the survival cohort, immediate hemostasis was achieved in 8 of 11 patients. Failure modes included pericardial entrapment by the epicardial occluder disk (n = 2) and a true-apex entry site that prevented hemostatic apposition of the endocardial disk (n = 1). Reactive pericardial effusion (192 ± 118 ml) accumulated 5 ± 1 days after the procedure, requiring 1-time drainage. At 3 months, LV function was preserved, and the device was endothelialized. Conclusions Direct percutaneous LV access and closure is feasible using real-time MRI. A commercial occluder achieved hemostasis without evident deleterious effects on the LV. Having established the concept, further clinical development of this approach appears realistic. PMID:22192372

Simulated patient, or so-called 'mystery-shopper', studies are a controversial, but potentially useful, approach to take when conducting health services research. To investigate the construct validity of survey questions relating to access to primary care included in the English GP Patient Survey. Observational study in 41 general practices in rural, urban, and inner-city settings in the UK. Between May 2010 and March 2011, researchers telephoned practices at monthly intervals, simulating patients requesting routine, but prompt, appointments. Seven measures of access and appointment availability, measured from the mystery-shopper contacts, were related to seven measures of practice performance from the GP Patient Survey. Practices with lower access scores in the GP Patient Survey had poorer access and appointment availability for five out of seven items measured directly, when compared with practices that had higher scores. Scores on items from the national survey that related to appointment availability were significantly associated with direct measures of appointment availability. Patient-satisfaction levels and the likelihood that patients would recommend their practice were related to the availability of appointments. Patients' reports of ease of telephone access in the national survey were unrelated to three out of four measures of practice call handling, but were related to the time taken to resolve an appointment request, suggesting responders' possible confusion in answering this question. Items relating to the accessibility of care in a the English GP patient survey have construct validity. Patients' satisfaction with their practice is not related to practice call handling, but is related to appointment availability.

Many individuals who are candidates for thoracic endovascular aortic repair (TEVAR) are found to have iliac artery anatomy and/or disease that preclude transfemoral endovascular access and require retroperitoneal surgical approach through more proximal arteries. This relatively more invasive technique could potentially affect the procedural outcomes. This study compares the retroperitoneal with transfemoral access used for TEVAR in a single center. In this study, 133 consecutive patients (96 men; mean age ± SD: 69.5 ± 14.7 years) who underwent TEVAR between 1994 and 2009 in a single center were retrospectively evaluated. The type of endovascular access was identified in all the patients. The basic demographics, access method, endograft type, 30-day morbidity and mortality rates, as well as procedure recordings including fluoroscopic and procedure duration, estimated blood loss, and duration of hospitalization were compared between the TEVAR procedures performed using a surgical retroperitoneal approach and those using the standard femoral access. Retroperitoneal access was used in 19 (14.3%; 13 women; mean age ± SD: 71 ± 12.2 years) and direct femoral access in 114 (85.7%; 24 women; mean age ± SD: 69 ± 15.4 years) patients. Two of the retroperitoneal accesses were obtained after failure of femoral approach. Techniques that were used included iliac artery conduit (seven patients), aortic artery conduit (eight patients), aortobifemoral artery graft conduit (one patient), and direct sheath introduction through the distal aorta (two patients) or common iliac artery (one patient). Retroperitoneal approach was used more frequently in women (35%) as compared with men (6%) (p = 0.0001). In all, 79% of the retroperitoneal approaches were associated with use of delivery sheath sizes larger than 24F (p = 0.049). TEVAR technical success was 100% with retroperitoneal and 97.3% with femoral access (p > 0.05). Thirty-day mortality rates were 0% and 8.8% and the rates of access artery injury were 5.3% and 4.4% in retroperitoneal and femoral access groups, respectively (p > 0.05). The incidence of retroperitoneal hematoma was significantly higher with retroperitoneal access (21% vs. 2.6%, p = 0.008). Additionally, retroperitoneal access was associated with significant increase in estimated blood loss and duration of hospitalization (p < 0.05). Type of access does not affect TEVAR success and the early mortality rate. Retroperitoneal approach is a valuable alternative technique in cases involving failed or impossible femoral access. However, this approach is associated with higher chances of retroperitoneal bleeding and longer procedural time and duration of hospitalization. Thoracic endografts with smaller delivery systems could minimize the need for this approach in the future. Copyright © 2011 Annals of Vascular Surgery Inc. All rights reserved.

Antiretroviral therapy (ART) has transformed HIV into a manageable illness. However, high levels of adherence must be maintained. Lack of access to basic resources (food, transportation, and housing) has been consistently associated with suboptimal ART adherence. Moving beyond such direct effects, this study takes a hierarchical resources approach in which the effects of access to basic resources on ART adherence are mediated through interpersonal resources (social support and care services) and personal resources (self-efficacy). Participants were 915 HIV-positive men and women living in Atlanta, GA, recruited from community centers and infectious disease clinics. Participants answered baseline questionnaires, and provided prospective data on ART adherence. Across a series of nested models, a consistent pattern emerged whereby lack of access to basic resources had indirect, negative effects on adherence, mediated through both lack of access to social support and services, and through lower treatment self-efficacy. There was also a significant direct effect of lack of access to transportation on adherence. Lack of access to basic resources negatively impacts ART adherence. Effects for housing instability and food insecurity were fully mediated through social support, access to services, and self-efficacy, highlighting these as important targets for intervention. Targeting service supports could be especially beneficial due to the potential to both promote adherence and to link clients with other services to supplement food, housing, and transportation. Inability to access transportation had a direct negative effect on adherence, suggesting that free or reduced cost transportation could positively impact ART adherence among disadvantaged populations.

The Internet is a common resource for applicants of hand surgery fellowships, however, the quality and accessibility of fellowship online information is unknown. The objectives of this study were to evaluate the accessibility of hand surgery fellowship Web sites and to assess the quality of information provided via program Web sites. Hand fellowship Web site accessibility was evaluated by reviewing the American Society for Surgery of the Hand (ASSH) on November 16, 2014 and the National Resident Matching Program (NRMP) fellowship directories on February 12, 2015, and performing an independent Google search on November 25, 2014. Accessible Web sites were then assessed for quality of the presented information. A total of 81 programs were identified with the ASSH directory featuring direct links to 32% of program Web sites and the NRMP directory directly linking to 0%. A Google search yielded direct links to 86% of program Web sites. The quality of presented information varied greatly among the 72 accessible Web sites. Program description (100%), fellowship application requirements (97%), program contact email address (85%), and research requirements (75%) were the most commonly presented components of fellowship information. Hand fellowship program Web sites can be accessed from the ASSH directory and, to a lesser extent, the NRMP directory. However, a Google search is the most reliable method to access online fellowship information. Of assessable programs, all featured a program description though the quality of the remaining information was variable. Hand surgery fellowship applicants may face some difficulties when attempting to gather program information online. Future efforts should focus on improving the accessibility and content quality on hand surgery fellowship program Web sites.

PathwayAccess: CellDesigner plugins for pathway databases.
Van Hemert, John L; Dickerson, Julie A
2010-09-15
CellDesigner provides a user-friendly interface for graphical biochemical pathway description. Many pathway databases are not directly exportable to CellDesigner models. PathwayAccess is an extensible suite of CellDesigner plugins, which connect CellDesigner directly to pathway databases using respective Java application programming interfaces. The process is streamlined for creating new PathwayAccess plugins for specific pathway databases. Three PathwayAccess plugins, MetNetAccess, BioCycAccess and ReactomeAccess, directly connect CellDesigner to the pathway databases MetNetDB, BioCyc and Reactome. PathwayAccess plugins enable CellDesigner users to expose pathway data to analytical CellDesigner functions, curate their pathway databases and visually integrate pathway data from different databases using standard Systems Biology Markup Language and Systems Biology Graphical Notation. Implemented in Java, PathwayAccess plugins run with CellDesigner version 4.0.1 and were tested on Ubuntu Linux, Windows XP and 7, and MacOSX. Source code, binaries, documentation and video walkthroughs are freely available at http://vrac.iastate.edu/~jlv.

Direct access refers to service users being able to refer themselves to physiotherapy without a third-party referral. It represents a model of practice supported globally by the profession, growing research evidence and health policy in some health systems. To the authors' knowledge, no research has been reported to ascertain the extent to which direct access is available within the physiotherapy profession within the European Union (EU). To survey member organisations of the World Confederation for Physical Therapy (WCPT); establish the number of member states within the EU where it is possible for individuals seeking physiotherapy services to self-refer; describe the legislative/regulatory and reimbursement contexts in which physiotherapy services are delivered; examine if physiotherapy practice is different in member states where direct access is permitted compared with member states where direct access is not permitted; and to describe the barriers and facilitators to direct access perceived by member organisations of the WCPT. Cross-sectional, online survey using a purposive sample. Member organisations of the WCPT in the EU. Direct access is not available in all member states of the EU, despite the majority having legislation to regulate the profession, and entry-level education programmes that produce graduates with the requisite competencies. Key barriers perceived are those that can influence policy development, including the views of the medical profession and politicians. Support of service users and politicians, as well as professional autonomy, are seen as key facilitators. These results represent the first report of a comprehensive mapping of direct access to physiotherapy and contexts within the EU. In over half of member states, service users can self-refer to physiotherapists. These results provide insights to further individuals' understanding about the similarities and differences in working practices and service delivery factors, such as reimbursement across and within EU member states. The synergies between barriers and facilitators indicate the importance of targeted advocacy strategies in the introduction of direct access/self-referral to physiotherapy.

Context and Spoken Word Recognition in a Novel Lexicon
ERIC Educational Resources Information Center
Revill, Kathleen Pirog; Tanenhaus, Michael K.; Aslin, Richard N.
2008-01-01
Three eye movement studies with novel lexicons investigated the role of semantic context in spoken word recognition, contrasting 3 models: restrictive access, access-selection, and continuous integration. Actions directed at novel shapes caused changes in motion (e.g., looming, spinning) or state (e.g., color, texture). Across the experiments,…

Water Framework Directive aiming to maintain and improve the aquatic environment in the EU was launched by the European Parliament in 2000. According to this directive, control of quantity is an ancillary element in securing good water quality and therefore measures on quantity, serving the objective of ensuring good quality should also be established. Accordingly, it is a comprehensive and coordinated package that will ensure all European waters to be protected according to a common standard. Therefore, it refers to all other Directives related to water resources management such as Urban Wastewater Treatment Directive Nitrates Directive, Drinking Water Directive, Integrated Pollution Prevention Control etc. Turkey, as a candidate state targeting full-membership, should comply the necessary preparations for the implementation of the "Water Framework Directive" as soon as possible. In this study, the necessary legislative, political, institutional, and technical attempts of the pre-accession countries have been discussed and effective recommendations have been offered for future activities in Turkey.

Around 17% of general practitioner (GP) consultations are for musculoskeletal conditions, which will rise as the population ages. Patient direct access to physiotherapy provides one solution, yet adoption in the National Health Service (NHS) has been slow. A pilot, pragmatic, non-inferiority, cluster randomised controlled trial (RCT) in general practice and physiotherapy services in the UK. Investigate feasibility of a main RCT. Adult patients registered in participating practices and consulting with a musculoskeletal problem. 4 general practices (clusters) randomised to provide GP-led care as usual or the addition of a patient direct access to physiotherapy pathway. Process outcomes and exploratory analyses of clinical and cost outcomes. Participant-level data were collected via questionnaires at identification, 2, 6 and 12 months and through medical records. The study statistician and research nurses were blinded to practice allocation. Of 2696 patients invited to complete study questionnaires, 978 participated (intervention group n=425, control arm n=553) and were analysed. Participant recruitment was completed in 6 months. Follow-up rates were 78% (6 months) and 71% (12 months). No evidence of selection bias was observed. The direct access pathway was used by 90% of patients in intervention practices needing physiotherapy. Some increase in referrals to physiotherapy occurred from one practice, although waiting times for physiotherapy did not increase (28 days before, 26 days after introduction of direct access). No safety issues were identified. Clinical and cost outcomes were similar in both groups. Exploratory estimates of between group effect (using 36-item Short Form Health Survey (SF-36) Physical Component Summary (PCS)) at 6 months was -0.28 (95% CI -1.35 to 0.79) and at 12 months 0.12 (95% CI -1.27 to 1.51). A full RCT is feasible and will provide trial evidence about the clinical and cost-effectiveness of patient direct access to physiotherapy. ISRCTN23378642.

Accessibility of Nitroxide Side Chains: Absolute Heisenberg Exchange Rates from Power Saturation EPR
Altenbach, Christian; Froncisz, Wojciech; Hemker, Roy; Mchaourab, Hassane; Hubbell, Wayne L.
2005-01-01
In site-directed spin labeling, the relative solvent accessibility of spin-labeled side chains is taken to be proportional to the Heisenberg exchange rate (Wex) of the nitroxide with a paramagnetic reagent in solution. In turn, relative values of Wex are determined by continuous wave power saturation methods and expressed as a proportional and dimensionless parameter Π. In the experiments presented here, NiEDDA is characterized as a paramagnetic reagent for solvent accessibility studies, and it is shown that absolute values of Wex can be determined from Π, and that the proportionality constant relating them is independent of the paramagnetic reagent and mobility of the nitroxide. Based on absolute exchange rates, an accessibility factor is defined (0 < ρ < 1) that serves as a quantitative measure of side-chain solvent accessibility. The accessibility factors for a nitroxide side chain at 14 different sites in T4 lysozyme are shown to correlate with a structure-based accessibility parameter derived from the crystal structure of the protein. These results provide a useful means for relating crystallographic and site-directed spin labeling data, and hence comparing crystal and solution structures. PMID:15994891

Macroscopic characterisations of Web accessibility
NASA Astrophysics Data System (ADS)
Lopes, Rui; Carriço, Luis
2010-12-01
The Web Science framework poses fundamental questions on the analysis of the Web, by focusing on how microscopic properties (e.g. at the level of a Web page or Web site) emerge into macroscopic properties and phenomena. One research topic on the analysis of the Web is Web accessibility evaluation, which centres on understanding how accessible a Web page is for people with disabilities. However, when framing Web accessibility evaluation on Web Science, we have found that existing research stays at the microscopic level. This article presents an experimental study on framing Web accessibility evaluation into Web Science's goals. This study resulted in novel accessibility properties of the Web not found at microscopic levels, as well as of Web accessibility evaluation processes themselves. We observed at large scale some of the empirical knowledge on how accessibility is perceived by designers and developers, such as the disparity of interpretations of accessibility evaluation tools warnings. We also found a direct relation between accessibility quality and Web page complexity. We provide a set of guidelines for designing Web pages, education on Web accessibility, as well as on the computational limits of large-scale Web accessibility evaluations.

Background Simulated patient, or so-called ‘mystery-shopper’, studies are a controversial, but potentially useful, approach to take when conducting health services research. Aim To investigate the construct validity of survey questions relating to access to primary care included in the English GP Patient Survey. Design and setting Observational study in 41 general practices in rural, urban, and inner-city settings in the UK. Method Between May 2010 and March 2011, researchers telephoned practices at monthly intervals, simulating patients requesting routine, but prompt, appointments. Seven measures of access and appointment availability, measured from the mystery-shopper contacts, were related to seven measures of practice performance from the GP Patient Survey. Results Practices with lower access scores in the GP Patient Survey had poorer access and appointment availability for five out of seven items measured directly, when compared with practices that had higher scores. Scores on items from the national survey that related to appointment availability were significantly associated with direct measures of appointment availability. Patient-satisfaction levels and the likelihood that patients would recommend their practice were related to the availability of appointments. Patients’ reports of ease of telephone access in the national survey were unrelated to three out of four measures of practice call handling, but were related to the time taken to resolve an appointment request, suggesting responders’ possible confusion in answering this question. Conclusion Items relating to the accessibility of care in a the English GP patient survey have construct validity. Patients’ satisfaction with their practice is not related to practice call handling, but is related to appointment availability. PMID:23561783

Spatial updating in area LIP is independent of saccade direction.
Heiser, Laura M; Colby, Carol L
2006-05-01
We explore the world around us by making rapid eye movements to objects of interest. Remarkably, these eye movements go unnoticed, and we perceive the world as stable. Spatial updating is one of the neural mechanisms that contributes to this perception of spatial constancy. Previous studies in macaque lateral intraparietal cortex (area LIP) have shown that individual neurons update, or "remap," the locations of salient visual stimuli at the time of an eye movement. The existence of remapping implies that neurons have access to visual information from regions far beyond the classically defined receptive field. We hypothesized that neurons have access to information located anywhere in the visual field. We tested this by recording the activity of LIP neurons while systematically varying the direction in which a stimulus location must be updated. Our primary finding is that individual neurons remap stimulus traces in multiple directions, indicating that LIP neurons have access to information throughout the visual field. At the population level, stimulus traces are updated in conjunction with all saccade directions, even when we consider direction as a function of receptive field location. These results show that spatial updating in LIP is effectively independent of saccade direction. Our findings support the hypothesis that the activity of LIP neurons contributes to the maintenance of spatial constancy throughout the visual field.

This study descriptively measured the universal accessibility of "accessible" fitness and recreational facilities for Ontarians living with mobility disabilities. The physical and social environments of 44 fitness and recreational facilities that identified as "accessible" were assessed using a modified version of the AIMFREE. None of the 44 facilities were completely accessible. Mean accessibility ratings ranged between 31 and 63 out of a possible 100. Overall, recreational facilities had higher accessibility scores than fitness centers, with significant differences found on professional support and training, entrance areas, and parking lot. A modest correlation was found between the availability of fitness programming and the overall accessibility of fitness-center specific facility areas. Overall, the physical and social environments of the 44 fitness and recreational facilities assessed were limited in their accessibility for persons with mobility disabilities. Future efforts should be directed at establishing and meeting universal accessibility guidelines for Canadian physical activity facilities.

Structural empowerment and burnout among Portuguese nursing staff: An explicative model.
Orgambídez-Ramos, Alejandro; Borrego-Alés, Yolanda; Vázquez-Aguado, Octavio; March-Amegual, Jaume
2017-11-01
Kanter's structural empowerment model was used to assess the influence of access to opportunities, resources, information and support on core burnout through global empowerment in a nursing sample in Portugal. The empowerment experience increases the levels of nursing professionals' satisfaction and performance preventing the emergence of burnout. However, the relationship between structural empowerment and burnout has been scarcely studied in Portugal. We conducted a cross-sectional correlational study assessing a final sample of 297 participants (62.13% response rate, 63.64% women). Model fit and mediation test were examined using structural equation modelling (path analysis). Access to opportunities and access to support had direct impact, through global empowerment, on core burnout, whereas access to resources had both direct and indirect impact on core burnout. The results validated the structural empowerment model and its application in nursing staff in Portugal. Professional training plans, the development of formal and informal support networks, and the availability of resources increase the levels of empowerment and decrease the likelihood of experiencing burnout in nursing professionals. © 2017 John Wiley & Sons Ltd.

Various companies are currently advertising or selling genetic tests over the internet using a model of provision referred to as 'direct-to-consumer' (DTC). This commercial offer of DTC genetic testing (GT) has fueled a number of scientific, ethical and policy debates. To date there have been few studies published regarding the users' perspective. This study aimed to obtain information regarding the issues raised by individuals who signed a petition in support of DTC GT and the 'unrestricted' access to their genetic information. We conducted qualitative content analysis of comments written by individuals who signed a public online petition initiated by DIYgenomics (CA, USA) to support "personal access to genetic information". Of the 523 individuals who signed the petition sponsored by DIYgenomics, 247 individuals also wrote individual comments. A content analysis of these comments reveals that petitioners raised six main issues in support of unrestricted access to DTC GT: that their ownership of their DNA should allow them to have unrestricted access to their genomic information; that they should have the right to their genomic information; that the government has no place in (further) regulating DTC GT; that healthcare professionals should not be placed as intermediaries when purchasing DTC GT services; that many petioners who had already obtained DTC GT had positive experiences with this model of provision; and that genealogy or ancestry DNA testing is one of the main activities petitioners wish to have 'unrestricted' or 'direct' access. These results give insight into why individuals may support unrestricted access to their genomic information and confirm some of the motivations of users for purchasing DTC GT. Our analysis also brings to the forefront themes that have been raised less often in empirical studies involving motivations to purchase DTC GT services; these include the strongly held beliefs of some petitioners that, since they own their DNA, they should have the right to access the information without (further) government control or physician involvement. Interestingly, the comments left by petitioners also reveal a certain distrust of governmental agencies and healthcare professionals. This urges us to further study the public's views of these services and the potential impact of these views in order to responsibly address the ongoing debate on DTC GT.

Utilisation of prehospital intravenous access.
Bester, B H; Sobuwa, Simpiwe
2014-07-22
To describe the use of intravenous (IV) therapy in the South African (SA) prehopsital setting, and to determine the proportion of prehopsital cannulations considered unnecessary when graded against the South African Triage Score (SATS) chart. The study was conducted in the prehospital emergency medical care setting in the Western Cape Province, SA. Using a descriptive research design, we looked at the report forms of patients treated and transported by personnel currently employed in the public sector, serving the urban and rural areas stipulated by the municipal boundaries. All medical and trauma cases in which establishment of IV access was documented for the month of April 2013 were included. Interhospital transfers, unsuccessful attempts at IV access and intraosseous cannulation were excluded. When graded against the SATS, prophylactic IV access was not justified in 42.3% of the total number of cases (N=149) in which it was established, and therefore added no direct benefit to the continuum of patient care. It is worth noting that 18.8% (n=39) of the IV lines were utilised for fluid administration, as opposed to 9.2% (n=19) for the administration of IV medications. In view of the paucity of studies indicating a direct benefit of out-of-hospital IV intervention, the practice of precautionary, protocol-driven prophylactic establishment of IV access should be evaluated. Current data suggest that in the absence of scientific evidence, IV access should only be initiated when it will benefit the patient immediately, and precautionary IV access, especially in non-injured patients, should be re-evaluated.

Collaborating groups typically show reduced recall relative to nominal groups, i.e., to the cumulated non-redundant recall of the same number of people remembering in isolation-a finding termed collaborative inhibition. Motivated by the results of several previous studies, this study examined in two experiments whether access to study context at test influences the effects of collaboration. In both experiments, subjects collaborated in triads or recalled previously studied material in isolation. Experiment 1 applied short versus prolonged retention intervals to vary access to study context at test, whereas Experiment 2 used the list-method directed forgetting task and applied remember versus forget instructions to modulate context access. In both experiments, collaborative inhibition was present when access to study context at test was intact (i.e., after the short delay and the remember instruction) but was eliminated when the access was impaired (i.e., after the prolonged delay and the forget instruction). Also, post-collaborative gains for individual recall were greater when context access was impaired and collaborative inhibition was eliminated. The findings demonstrate a critical role of access to study context at test for collaborative inhibition, indicating that impaired context access may reflect a general boundary condition for the recall impairment. The possible role of context reactivation processes for beneficial effects of social recall is discussed.

The most prominent features of hypervitaminosis A in rats are spontaneous fractures and anorexia. Since caloric restriction induces alterations in bone, some effects could be secondary to loss of appetite. To clarify the mechanisms behind vitamin A-induced bone fragility it is necessary to distinguish between direct and indirect effects. In this study we compared rats fed high doses of vitamin A both with pair-fed controls, which were fed the same amount of chow as that consumed by the vitamin A group to keep food intake the same, and to controls with free access to food. In contrast to the pair-fed animals, rats in the free access group fed high doses of vitamin A for 7 days had 13% lower food intake, 15% lower body weight, and 2.7% shorter femurs compared with controls. In addition, serum biomarkers of bone turnover were reduced. Peripheral quantitative computed tomography of the femurs showed that the bone mineral content, cross sectional area, and periosteal circumference were similarly reduced in the pair-fed and free access groups. However, bone mineral density (BMD) and cortical parameters were only significantly decreased in the free access group. Our data indicate that the major direct short-term effect of high doses of vitamin A on rat bone is a reduced bone diameter, whereas the effects on bone length, serum biomarkers of bone turnover, BMD, and bone cortex appear to be mainly indirect, caused by a systemic toxicity with loss of appetite, reduced food intake, and general effects on growth.

Meckel's cave access: anatomic study comparing the endoscopic transantral and endonasal approaches.
Van Rompaey, Jason; Suruliraj, Anand; Carrau, Ricardo; Panizza, Benedict; Solares, C Arturo
2014-04-01
Recent advances in endonasal endoscopy have facilitated the surgical access to the lateral skull base including areas such as Meckel's cave. This approach has been well documented, however, few studies have outlined transantral specific access to Meckel's. A transantral approach provides a direct pathway to this region obviating the need for extensive endonasal and transsphenoidal resection. Our aim in this study is to compare the anatomical perspectives obtained in endonasal and transantral approaches. We prepared 14 cadaveric specimens with intravascular injections of colored latex. Eight cadavers underwent endoscopic endonasal transpterygoid approaches to Meckel's cave. Six additional specimens underwent an endoscopic transantral approach to the same region. Photographic evidence was obtained for review. 30 CT scans were analyzed to measure comparative distances to Meckel's cave for both approaches. The endoscopic approaches provided a direct access to the anterior and inferior portions of Meckel's cave. However, the transantral approach required shorter instrumentation, and did not require clearing of the endonasal corridor. This approach gave an anterior view of Meckel's cave making posterior dissection more difficult. A transantral approach to Meckel's cave provides access similar to the endonasal approach with minimal invasiveness. Some of the morbidity associated with extensive endonasal resection could possibly be avoided. Better understanding of the complex skull base anatomy, from different perspectives, helps to improve current endoscopic skull base surgery and to develop new alternatives, consequently, leading to improvements in safety and efficacy.

2011-10-01
To compare the uptake of Down syndrome screening by women following referral by direct access and general practitioner (GP) modes. The method of referral by either GP or direct access, for women who booked into prenatal care in Hull and East Yorkshire in 2010, was analysed using data collected from the Protos database at the Women and Children's Hospital, Hull. Subsequently, the uptake of first and second trimester screening for Down syndrome was reviewed by combining the Protos database to the screening data collected by the Clinical Biochemistry Laboratory at Hull Royal Infirmary, Hull. Women booked into prenatal care significantly earlier when referred by GP in comparison to direct access with a significant difference in screening uptake of 49.5 and 42.7%, respectively. The ratio of uptake between first and second trimester screening was not significantly different. Further research on the new direct access method of referral is required, as it may have a role in the uptake of prenatal screening for Down syndrome. More time is needed to show a definitive effect.

Gambling disorders affect about one percent of adults. Effective treatments are available but only a small proportion of affected individuals will choose to attend formal treatment. As a result, self-directed treatments have also been developed and found effective. Self-directed treatments provide individuals with information and support to initiate a recovery program without attending formal treatment. In previous research we developed an telephone-based intervention package that helps people to be motivated to tackle their gambling problem and to use basic behavioral and cognitive change strategies. The present study will investigate the efficacy of this self-directed intervention offered as a free online resource. The Internet is an excellent modality in which to offer self-directed treatment for gambling problems. The Internet is increasingly accessible to members of the public and is frequently used to access health-related information. Online gambling sites are also becoming more popular gambling platforms. A randomized clinical trial (N=180) will be conducted in which individuals with gambling problems who are not interested in attending formal treatment are randomly assigned to have access to an online self-directed intervention or to a comparison condition. The comparison condition will be an alternative website that offers a self-assessment of gambling involvement and gambling-related problems. The participant's use of the resources and their gambling involvement (days of gambling, dollars loss) and their gambling problems will be tracked for a twelve month follow-up period. The results of this research will be important for informing policy-makers who are developing treatment systems. ISRCTN06220098.

Repetition priming was used to assess how proficiency and the ease or difficulty of lexical access influence bilingual translation. Two experiments, conducted at different universities with different Spanish-English bilingual populations and materials, showed repetition priming in word translation for same-direction and different-direction repetitions. Experiment 1, conducted in an English-dominant environment, revealed an effect of translation direction but not of direction match, whereas Experiment 2, conducted in a more balanced bilingual environment, showed an effect of direction match but not of translation direction. A combined analysis on the items common to both studies revealed that bilingual proficiency was negatively associated with response time (RT), priming, and the degree of translation asymmetry in RTs and priming. An item analysis showed that item difficulty was positively associated with RTs, priming, and the benefit of same-direction over different-direction repetition. Thus, although both participant accuracy and item accuracy are indices of learning, they have distinct effects on translation RTs and on the learning that is captured by the repetition-priming paradigm.

Evaluation of spatial accessibility to primary healthcare using GIS
NASA Astrophysics Data System (ADS)
Jamtsho, S.; Corner, R. J.
2014-11-01
Primary health care is considered to be one of the most important aspects of the health care system in any country, which directly helps in improving the health of the population. Potential spatial accessibility is a very important component of the primary health care system. One technique for studying spatial accessibility is by computing a gravity-based measure within a geographic information system (GIS) framework. In this study, straight-line distances between the associated population clusters and the health facilities and the provider-to-population ratio were used to compute the spatial accessibility of the population clusters for the whole country. Bhutan has been chosen as the case study area because it is quite easy to acquire and process data for the whole country due to its small size and population. The spatial accessibility measure of the 203 sub-districts shows noticeable disparities in health care accessibility in this country with about only 19 sub-districts achieving good health accessibility ranking. This study also examines a number of different health accessibility policy scenarios which can assist in identifying the most effective health policy from amongst many probable planning scenarios. Such a health accessibility measuring system can be incorporated into an existing spatial health system in developing countries to facilitate the proper planning and equitable distribution of health resources.

Routes to the past: neural substrates of direct and generative autobiographical memory retrieval.
Addis, Donna Rose; Knapp, Katie; Roberts, Reece P; Schacter, Daniel L
2012-02-01
Models of autobiographical memory propose two routes to retrieval depending on cue specificity. When available cues are specific and personally-relevant, a memory can be directly accessed. However, when available cues are generic, one must engage a generative retrieval process to produce more specific cues to successfully access a relevant memory. The current study sought to characterize the neural bases of these retrieval processes. During functional magnetic resonance imaging (fMRI), participants were shown personally-relevant cues to elicit direct retrieval, or generic cues (nouns) to elicit generative retrieval. We used spatiotemporal partial least squares to characterize the spatial and temporal characteristics of the networks associated with direct and generative retrieval. Both retrieval tasks engaged regions comprising the autobiographical retrieval network, including hippocampus, and medial prefrontal and parietal cortices. However, some key neural differences emerged. Generative retrieval differentially recruited lateral prefrontal and temporal regions early on during the retrieval process, likely supporting the strategic search operations and initial recovery of generic autobiographical information. However, many regions were activated more strongly during direct versus generative retrieval, even when we time-locked the analysis to the successful recovery of events in both conditions. This result suggests that there may be fundamental differences between memories that are accessed directly and those that are recovered via the iterative search and retrieval process that characterizes generative retrieval.

However, many regions were activated more strongly during direct versus generative retrieval, even when we time-locked the analysis to the successful recovery of events in both conditions. This result suggests that there may be fundamental differences between memories that are accessed directly and those that are recovered via the iterative search and retrieval process that characterizes generative retrieval.

Traditional techniques for obtaining percutaneous renal access utilize continuous fluoroscopy. In an attempt to minimize radiation exposure, we describe a novel laser direct alignment radiation reduction technique (DARRT) for percutaneous access and test it in a bench-top model. In this randomized-controlled bench-top study, 20 medical personnel obtained renal accesses using both the conventional bullseye technique and the laser DARRT. The primary endpoint was total fluoroscopy time. Secondary endpoints included insertion time, puncture attempts, course corrections, and subjective procedural difficulty. In the laser DARRT, fluoroscopy was used with the C-arm positioned with the laser beam at a 30° angle. The access needle and hub were aligned with the laser beam. Effective caliceal puncture was confirmed with fluoroscopy and direct vision. The Paired samples Wilcoxon signed rank test was used for statistical analysis with significance at p < 0.05. A total of 120 needle placements were recorded. Fluoroscopy time for needle access using the laser DARRT was significantly lower than the bullseye technique in all groups as follows: attendings (7.09 vs 18.51 seconds; p < 0.001), residents (6.55 vs 13.93 seconds; p = 0.001), and medical students (6.69 vs 20.22 seconds; p < 0.001). Students rated the laser DARRT easier to use (2.56 vs 4.89; p < 0.001). No difference was seen in total access time, puncture attempts, or course corrections between techniques. The laser DARRT reduced fluoroscopy time by 63%, compared with the conventional bullseye technique. The least experienced users found the laser DARRT significantly easier to learn. This novel technique is promising and merits additional testing in animal and human models.

Immunization information systems (IIS) are population-based and confidential computerized systems maintained by public health agencies containing individual data on immunizations from participating health care providers. IIS hold comprehensive vaccination histories given across providers and over time. An important aspect to IIS is the clinical decision support for immunizations (CDSi), consisting of vaccine forecasting algorithms to determine needed immunizations. The study objective was to analyze the CDSi presentation by IIS in Minnesota (Minnesota Immunization Information Connection [MIIC]) through direct access by IIS interface and by access through electronic health records (EHRs) to outline similarities and differences. The immunization data presented were similar across the three systems examined, but with varying ability to integrate data across MIIC and EHR, which impacts immunization data reconciliation. Study findings will lead to better understanding of immunization data display, clinical decision support, and user functionalities with the ultimate goal of promoting IIS CDSi to improve vaccination rates.

Identification and Illustration of Insecure Direct Object References and their Countermeasures
NASA Astrophysics Data System (ADS)
KumarShrestha, Ajay; Singh Maharjan, Pradip; Paudel, Santosh

The insecure direct object reference simply represents the flaws in the system design without the full protection mechanism for the sensitive system resources or data. It basically occurs when the web application developer provides direct access to objects in accordance with the user input. So any attacker can exploit this web vulnerability and gain access to privileged information by bypassing the authorization. The main aim of this paper is to demonstrate the real effect and the identification of the insecure direct object references and then to provide the feasible preventive solutions such that the web applications do not allow direct object references to be manipulated by attackers. The experiment of the insecure direct object referencing is carried out using the insecure J2EE web application called WebGoat and its security testing is being performed using another JAVA based tool called BURP SUITE. The experimental result shows that the access control check for gaining access to privileged information is a very simple problem but at the same time its correct implementation is a tricky task. The paper finally presents some ways to overcome this web vulnerability.

Fast converging minimum probability of error neural network receivers for DS-CDMA communications.
Matyjas, John D; Psaromiligkos, Ioannis N; Batalama, Stella N; Medley, Michael J
2004-03-01
We consider a multilayer perceptron neural network (NN) receiver architecture for the recovery of the information bits of a direct-sequence code-division-multiple-access (DS-CDMA) user. We develop a fast converging adaptive training algorithm that minimizes the bit-error rate (BER) at the output of the receiver. The adaptive algorithm has three key features: i) it incorporates the BER, i.e., the ultimate performance evaluation measure, directly into the learning process, ii) it utilizes constraints that are derived from the properties of the optimum single-user decision boundary for additive white Gaussian noise (AWGN) multiple-access channels, and iii) it embeds importance sampling (IS) principles directly into the receiver optimization process. Simulation studies illustrate the BER performance of the proposed scheme.

A middle aged patient presented with acute ischemic stroke due to basilar artery occlusion. The patient clinically deteriorated despite intravenous thrombolysis and was referred for mechanical thrombectomy. The right vertebral artery was occluded and could not be accessed despite attempting various shaped catheters, even when a radial artery access was used. The left vertebral artery ended in the posterior inferior cerebellar artery. Eventually, ultrasound guided V3 segment vertebral artery direct puncture was successfully done and the procedure was completed. No access related complications were encountered. Direct cervical arterial puncture can be safely used by experienced operators as a last resort in acute stroke cases with difficult access.

While advanced diagnostic imaging is a large contributor to the growth in health care costs, direct-access to physical therapy is associated with decreased rates of diagnostic imaging. No study has systematically evaluated with evidence-based criteria the appropriateness of advanced diagnostic imaging, including magnetic resonance imaging (MRI), when ordered by physical therapists. The primary purpose of this study was to describe the appropriateness of magnetic resonance imaging (MRI) or magnetic resonance arthrogram (MRA) exams ordered by physical therapists in a direct-access sports physical therapy clinic. Retrospective observational study of practice. Greater than 80% of advanced diagnostic imaging orders would have an American College of Radiology (ACR) Appropriateness Criteria rating of greater than 6, indicating an imaging order that is usually appropriate. A 2-year retrospective analysis identified 108 MRI/MRA examination orders from four physical therapists. A board-certified radiologist determined the appropriateness of each order based on ACR appropriateness criteria. The principal investigator and co-investigator radiologist assessed agreement between the clinical diagnosis and MRI/surgical findings. Knee (31%) and shoulder (25%) injuries were the most common. Overall, 55% of injuries were acute. The mean ACR rating was 7.7; scores from six to nine have been considered appropriate orders and higher ratings are better. The percentage of orders complying with ACR appropriateness criteria was 83.2%. Physical therapist's clinical diagnosis was confirmed by MRI/MRA findings in 64.8% of cases and was confirmed by surgical findings in 90% of cases. Physical therapists providing musculoskeletal primary care in a direct-access sports physical therapy clinic appropriately ordered advanced diagnostic imaging in over 80% of cases. Future research should prospectively compare physical therapist appropriateness and utilization to other groups of providers and explore the effects of physical therapist imaging privileging on outcomes.

This study aimed to examine whether general practitioner (GP) practice locations in remote and rural areas affected the pattern of direct access echocardiography referral and to assess any variations in echocardiographic findings. All referrals made by all GP practices in the Scottish Highlands over a 36-month period were analysed. Referral patterns were examined according to distance and rurality based on the Scottish Government's Urban-Rural Classification. Reasons for referral and cardiac abnormality detection rates were also examined. In total, 1188 referrals were made from 49 different GP practices; range of referral rates was 0.3-20.1 per 1000 population with a mean of 6.5 referrals per 1000 population. Referral rates were not significantly different between urban and rural practices after correction for population size. There was no correlation between the referral rates and the distance from the centre (r2=0.004, p=0.65). The most common reason for referral was the presence of new murmur (46%). The most common presenting symptom was breathlessness (44%). Overall, 28% of studies had significant abnormal findings requiring direct input from a cardiologist. There was no clear relationship between referral rates and cardiac abnormality detection rates (r2=0.07, p=0.37). The average cardiac abnormality detection rate was 56%, (range 52-60%), with no variation based on rurality (p=0.891). In this cohort, rurality and distance were not barriers to an equitable direct access echocardiography service. Cardiac abnormality detection rates are consistent with that of other studies.

Health policies increasingly promote e-health developments (e.g., consumers' access to online health information) to engage patients in their health care. In order to make these developments available for culturally and socially diverse communities, not only do Internet accessibility, literacy and e-health literacy need to be taken into account, but consumers' preferences and information seeking behaviours for accessing health information have also to be understood. These considerations are crucial when designing major new health policy directions, especially for migration destination countries with culturally diverse populations, such as Australia. The aim of this study was to examine how people from a culturally and linguistically diverse (CALD) community use telecommunications (phone, mobile, Internet) to access health information. A case study was conducted using a questionnaire exploring the use of telecommunications to access health information among CALD people. The study was carried out at a community health centre in a socially and economically disadvantaged area of Melbourne, a city of 4 million people with a large CALD and migrant population. Questionnaires were translated into three languages and interpreters were provided. Fifty-nine questionnaires were completed by users of the community health centre. Most of the CALD participants did not have access to the Internet at home and very few reported using telecommunications to access health information. The findings of the study suggest that telecommunications are not necessarily perceived to be an important channel for accessing health information by members of the CALD community.

There are constraints embedded in medical record structure that limit use by patients in self-directed disease management. Through systematic review of the literature from a critical perspective, four characteristics that either enhance or mitigate the influence of medical record structure on patient utilization of an electronic patient record (EPR) system have been identified: environmental pressures, physician centeredness, collaborative organizational culture, and patient centeredness. An evaluation framework is proposed for use when considering adaptation of existing EPR systems for online patient access. Exemplars of patient-accessible EPR systems from the literature are evaluated utilizing the framework. From this study, it appears that traditional information system research and development methods may not wholly capture many pertinent social issues that arise when expanding access of EPR systems to patients. Critically rooted methods such as action research can directly inform development strategies so that these systems may positively influence health outcomes.

One of the most frequent and strong arguments for supporting direct-to-consumer prescription drug advertising (DTCA) as a positive influence on individuals and society is that DTCA could contribute to improving patients' medication adherence, but systematic empirical research testing this proposed effect is scant. To address this gap and provide an answer to the unresolved question about DTCA effects, this study examined the relationship between overall DTCA exposure and patients' medication adherence through the mechanism of media priming effect increasing medication-related belief accessibility. Results from a survey with a sample of prescription blood thinner takers revealed no significant relationships between DTCA exposure and patients' belief accessibility regarding their medical conditions and drug benefits and risks, and no support for the hypothesized relationship between DTCA exposure and medication adherence. The findings are discussed within the context of DTCA effect research literature, and theoretical and practical implications are presented.

National Aeronautics and Space Administration (NASA) CubeSat missions are expected to grow rapidly in the next decade. Higher data rate CubeSats are transitioning away from Amateur Radio bands to higher frequency bands. A high-level communication architecture for future space-to-ground CubeSat communication was proposed within NASA Goddard Space Flight Center. This architecture addresses CubeSat direct-to-ground communication, CubeSat to Tracking Data Relay Satellite System (TDRSS) communication, CubeSat constellation with Mothership direct-to-ground communication, and CubeSat Constellation with Mothership communication through K-Band Single Access (KSA). A study has been performed to explore this communication architecture, through simulations, analyses, and identifying technologies, to develop the optimum communication concepts for CubeSat communications. This paper presents details of the simulation and analysis that include CubeSat swarm, daughter ship/mother ship constellation, Near Earth Network (NEN) S and X-band direct to ground link, TDRSS Multiple Access (MA) array vs Single Access mode, notional transceiver/antenna configurations, ground asset configurations and Code Division Multiple Access (CDMA) signal trades for daughter ship/mother ship CubeSat constellation inter-satellite cross link. Results of space science X-band 10 MHz maximum achievable data rate study are summarized. CubeSat NEN Ka-Band end-to-end communication analysis is provided. Current CubeSat communication technologies capabilities are presented. Compatibility test of the CubeSat transceiver through NEN and SN is discussed. Based on the analyses, signal trade studies and technology assessments, the desired CubeSat transceiver features and operation concepts for future CubeSat end-to-end communications are derived.

Improving access to safe abortion is an essential strategy in the provision of universal access to reproductive health care. Australians are largely supportive of the provision of abortion and its decriminalization. However, the lack of data and the complex legal and service delivery situation impacts upon access for women seeking an early termination of pregnancy. There are no systematic reviews from a health services perspective to help direct health planners and policy makers to improve access comprehensive medical and early surgical abortion in high income countries. This review therefore aims to identify quality studies of abortion services to provide insight into how access to services can be improved in Australia. We undertook a structured search of six bibliographic databases and hand-searching to ascertain peer reviewed primary research in English between 2005 and 2015. Qualitative and quantitative study designs were deemed suitable for inclusion. A deductive content analysis methodology was employed to analyse selected manuscripts based upon a framework we developed to examine access to early abortion services. This review identified the dimensions of access to surgical and medical abortion at clinic or hospital-outpatient based abortion services, as well as new service delivery approaches utilising a remote telemedicine approach. A range of factors, mostly from studies in the United Kingdom and United States of America were found to facilitate improved access to abortion, in particular, flexible service delivery approaches that provide women with cost effective options and technology based services. Standards, recommendations and targets were also identified that provided services and providers with guidance regarding the quality of abortion care. Key insights for service delivery in Australia include the: establishment of standards, provision of choice of procedure, improved provider education and training and the expansion of telemedicine for medical abortion. However, to implement such directives leadership is required from Australian medical, nursing, midwifery and pharmacy practitioners, academic faculties and their associated professional associations. In addition, political will is needed to nationally decriminalise abortion and ensure dedicated public provision that is based on comprehensive models tailored for all populations.

Performance model-directed data sieving for high-performance I/O
DOE Office of Scientific and Technical Information (OSTI.GOV)
Chen, Yong; Lu, Yin; Amritkar, Prathamesh
2014-09-10
Many scientific computing applications and engineering simulations exhibit noncontiguous I/O access patterns. Data sieving is an important technique to improve the performance of noncontiguous I/O accesses by combining small and noncontiguous requests into a large and contiguous request. It has been proven effective even though more data are potentially accessed than demanded. In this study, we propose a new data sieving approach namely performance model-directed data sieving, or PMD data sieving in short. It improves the existing data sieving approach from two aspects: (1) dynamically determines when it is beneficial to perform data sieving; and (2) dynamically determines how tomore » perform data sieving if beneficial. It improves the performance of the existing data sieving approach considerably and reduces the memory consumption as verified by both theoretical analysis and experimental results. Given the importance of supporting noncontiguous accesses effectively and reducing the memory pressure in a large-scale system, the proposed PMD data sieving approach in this research holds a great promise and will have an impact on high-performance I/O systems.« less

Airport Choice in Sao Paulo Metropolitan Area: An Application of the Conditional Logit Model
NASA Technical Reports Server (NTRS)
Moreno, Marcelo Baena; Muller, Carlos
2003-01-01
Using the conditional LOGIT model, this paper addresses the airport choice in the Sao Paulo Metropolitan Area. In this region, Guarulhos International Airport (GRU) and Congonhas Airport (CGH) compete for passengers flying to several domestic destinations. The airport choice is believed to be a result of the tradeoff passengers perform considering airport access characteristics, airline level of service characteristics and passenger experience with the analyzed airports. It was found that access time to the airports better explain the airport choice than access distance, whereas direct flight frequencies gives better explanation to the airport choice than the indirect (connections and stops) and total (direct plus indirect) flight frequencies. Out of 15 tested variables, passenger experience with the analyzed airports was the variable that best explained the airport choice in the region. Model specifications considering 1, 2 or 3 variables were tested. The model specification most adjusted to the observed data considered access time, direct flight frequencies in the travel period (morning or afternoon peak) and passenger experience with the analyzed airports. The influence of these variables was therefore analyzed across market segments according to departure airport and flight duration criteria. The choice of GRU (located neighboring Sao Paulo city) is not well explained by the rationality of access time economy and the increase of the supply of direct flight frequencies, while the choice of CGH (located inside Sao Paulo city) is. Access time was found to be more important to passengers flying shorter distances while direct flight frequencies in the travel period were more significant to those flying longer distances. Keywords: Airport choice, Multiple airport region, Conditional LOGIT model, Access time, Flight frequencies, Passenger experience with the analyzed airports, Transportation planning

2011-06-01
In healthcare, mobile computing made possible by smartphones is becoming an important tool among healthcare professionals. However, currently there is very little research into the effectiveness of such applications of technology. This study aims to present a framework for a smartphone application to give doctors mobile access to patient information, then review the consequences of its use and discuss its future direction. Since 2003 when Samsung Medical Center introduced its first mobile application, a need to develop a new application targeting the latest smartphone technology was identified. To that end, an application named Dr. SMART S was officially launched on December 22nd, 2010. We analyzed the usage data of the application for a month until April 25th, 2011. On average, 170 doctors (13% of the entire body of doctors) logged on 2.4 times per day and that number keeps growing. The number was uniformly distributed across all working hours, with exceptions of heavy accesses around 6-8 AM and 4-6 PM when doctors do their regular rounds to see the patients. The most commonly accessed content was inpatient information, this constituted 78.6% of all accesses, within this 50% was to accesses lab results. Looking at the usage data, we can see the use of Dr. SMART S by doctors is growing in sync with the popularity of smartphones. Since u-Health seem an inevitable future trend, a more rigorous study needs to be conducted on how such mobile applications as Dr. SMART S affect the quality of care and patient safety to derive directions for further improvements.

Access control and privilege management in electronic health record: a systematic literature review.
Jayabalan, Manoj; O'Daniel, Thomas
2016-12-01
This study presents a systematic literature review of access control for electronic health record systems to protect patient's privacy. Articles from 2006 to 2016 were extracted from the ACM Digital Library, IEEE Xplore Digital Library, Science Direct, MEDLINE, and MetaPress using broad eligibility criteria, and chosen for inclusion based on analysis of ISO22600. Cryptographic standards and methods were left outside the scope of this review. Three broad classes of models are being actively investigated and developed: access control for electronic health records, access control for interoperability, and access control for risk analysis. Traditional role-based access control models are extended with spatial, temporal, probabilistic, dynamic, and semantic aspects to capture contextual information and provide granular access control. Maintenance of audit trails and facilities for overriding normal roles to allow full access in emergency cases are common features. Access privilege frameworks utilizing ontology-based knowledge representation for defining the rules have attracted considerable interest, due to the higher level of abstraction that makes it possible to model domain knowledge and validate access requests efficiently.

To examine the financial impact health information exchange (HIE) in emergency departments (EDs). We studied all ED encounters over a 13-month period in which HIE data were accessed in all major emergency departments Memphis, Tennessee. HIE access encounter records were matched with similar encounter records without HIE access. Outcomes studied were ED-originated hospital admissions, admissions for observation, laboratory testing, head CT, body CT, ankle radiographs, chest radiographs, and echocardiograms. Our estimates employed generalized estimating equations for logistic regression models adjusted for admission type, length of stay, and Charlson co-morbidity index. Marginal probabilities were used to calculate changes in outcome variables and their financial consequences. HIE data were accessed in approximately 6.8% of ED visits across 12 EDs studied. In 11 EDs directly accessing HIE data only through a secure Web browser, access was associated with a decrease in hospital admissions (adjusted odds ratio (OR)=0.27; p<0001). In a 12th ED relying more on print summaries, HIE access was associated with a decrease in hospital admissions (OR=0.48; p<0001) and statistically significant decreases in head CT use, body CT use, and laboratory test ordering. Applied only to the study population, HIE access was associated with an annual cost savings of $1.9 million. Net of annual operating costs, HIE access reduced overall costs by $1.07 million. Hospital admission reductions accounted for 97.6% of total cost reductions. Access to additional clinical data through HIE in emergency department settings is associated with net societal saving.

Speed control system for an access gate
DOE Office of Scientific and Technical Information (OSTI.GOV)
Bzorgi, Fariborz M
2012-03-20
An access control apparatus for an access gate. The access gate typically has a rotator that is configured to rotate around a rotator axis at a first variable speed in a forward direction. The access control apparatus may include a transmission that typically has an input element that is operatively connected to the rotator. The input element is generally configured to rotate at an input speed that is proportional to the first variable speed. The transmission typically also has an output element that has an output speed that is higher than the input speed. The input element and the outputmore » element may rotate around a common transmission axis. A retardation mechanism may be employed. The retardation mechanism is typically configured to rotate around a retardation mechanism axis. Generally the retardation mechanism is operatively connected to the output element of the transmission and is configured to retard motion of the access gate in the forward direction when the first variable speed is above a control-limit speed. In many embodiments the transmission axis and the retardation mechanism axis are substantially co-axial. Some embodiments include a freewheel/catch mechanism that has an input connection that is operatively connected to the rotator. The input connection may be configured to engage an output connection when the rotator is rotated at the first variable speed in a forward direction and configured for substantially unrestricted rotation when the rotator is rotated in a reverse direction opposite the forward direction. The input element of the transmission is typically operatively connected to the output connection of the freewheel/catch mechanism.« less

Background Health policies increasingly promote e-health developments (e.g., consumers’ access to online health information) to engage patients in their health care. In order to make these developments available for culturally and socially diverse communities, not only do Internet accessibility, literacy and e-health literacy need to be taken into account, but consumers’ preferences and information seeking behaviours for accessing health information have also to be understood. These considerations are crucial when designing major new health policy directions, especially for migration destination countries with culturally diverse populations, such as Australia. The aim of this study was to examine how people from a culturally and linguistically diverse (CALD) community use telecommunications (phone, mobile, Internet) to access health information. Design and Methods A case study was conducted using a questionnaire exploring the use of telecommunications to access health information among CALD people. The study was carried out at a community health centre in a socially and economically disadvantaged area of Melbourne, a city of 4 million people with a large CALD and migrant population. Questionnaires were translated into three languages and interpreters were provided. Fifty-nine questionnaires were completed by users of the community health centre. Results Most of the CALD participants did not have access to the Internet at home and very few reported using telecommunications to access health information. Conclusions The findings of the study suggest that telecommunications are not necessarily perceived to be an important channel for accessing health information by members of the CALD community.

Review of manual control methods for handheld maneuverable instruments.
Fan, Chunman; Dodou, Dimitra; Breedveld, Paul
2013-06-01
By the introduction of new technologies, surgical procedures have been varying from free access in open surgery towards limited access in minimal access surgery. Improving access to difficult-to-reach anatomic sites, e.g. in neurosurgery or percutaneous interventions, needs advanced maneuverable instrumentation. Advances in maneuverable technology require the development of dedicated methods enabling surgeons to stay in direct, manual control of these complex instruments. This article gives an overview of the state-of-the-art in the development of manual control methods for handheld maneuverable instruments. It categorizes the manual control methods in three levels: a) number of steerable segments, b) number of Degrees Of Freedom (DOF), and c) coupling between control motion of the handle and steering motion of the tip. The literature research was completed by using Web of Science, Scopus and PubMed. The study shows that in controlling single steerable segments, direct as well as indirect control methods have been developed, whereas in controlling multiple steerable segments, a gradual shift can be noticed from parallel and serial control to integrated control. The development of multi-segmented maneuverable instruments is still at an early stage, and an intuitive and effective method to control them has to become a primary focus in the domain of minimal access surgery.

Application and Utility of iPads in Pediatric Tele-echocardiography.
Colombo, Jamie N; Seckeler, Michael D; Barber, Brent J; Krupinski, Elizabeth A; Weinstein, Ronald S; Sisk, David; Lax, Daniela
2016-05-01
Telemedicine is used with increasing frequency to improve patient care in remote areas. The interpretation of medical imaging on iPad(®) (Apple, Cupertino, CA) tablets has been reported to be accurate. There are no studies on the use of iPads for interpretation of pediatric echocardiograms. We compared the quality of echo images, diagnostic accuracy, and review time using three different modalities: remote access on an iPad Air (iPad), remote access via a computer (Remote), and direct access on a computer linked through Ethernet to the server, the "gold standard" (Direct). Fifty consecutive archived pediatric echocardiograms were interpreted using the three modalities. Studies were analyzed blindly by three pediatric cardiologists; review time, diagnostic accuracy, and image quality were documented. Diagnostic accuracy was assessed by comparing the study diagnoses with the official diagnosis in the patient's chart. Discrepancies between diagnoses were graded as major (more than one grade difference) or minor (one grade difference in severity of lesion). There were no significant differences in accuracy among the three modalities. There was one major discrepancy (size of patent ductus arteriosus); all others were minor, hemodynamically insignificant. Image quality ratings were better for iPad than Remote; Direct had the highest ratings. Review times (mean [standard deviation] minutes) were longest for iPad (5.89 [3.87]) and then Remote (4.72 [2.69]), with Direct having the shortest times (3.52 [1.42]) (p < 0.0001). Pediatric echocardiograms can be interpreted using convenient, portable devices while preserving accuracy and quality with slightly longer review times (1-2 min). These findings are important in the current era of increasing need for mobile health.

To describe technical details, success rate, and advantages of direct puncture of the thoracic duct (TD) under direct ultrasound (US) guidance at venous insertion in the left neck. All patients who underwent attempted thoracic duct embolization (TDE) via US-guided retrograde TD access in the left neck were retrospectively reviewed. Indications for lymphangiography were iatrogenic chyle leak, pulmonary lymphangiectasia, and plastic bronchitis. Ten patients with mean age 41.4 years (range, 21 d to 72 y) underwent US-guided TD access via the left neck. Technical details, procedural times, and clinical outcomes were evaluated. TD access time was defined as time from start of procedure to successful access of TD, and total procedural time was defined from start of procedure until TDE. All attempts at TD access via the neck were successful. Technical and clinical success of TDE was 60%. There were no complications. Mean TD access time was 17 minutes (range, 2-47 min), and mean total procedure time was 49 minutes (range, 25-69 min). Mean follow-up time was 5.4 months (range, 3-10 months). TDE via US-guided access in the left neck is technically feasible and safe with a potential decrease in procedure time and elimination of oil-based contrast material. Copyright © 2016 SIR.

Increasing numbers of patients have direct access to their electronic health records (EHRs). Proponents of direct access argue that it empowers patients by making them more informed and offering them more control over their health and care. According to some proponents of patients' access to EHRs, clinicians' concerns about potential negative implications are grounded in a form of paternalism that protects clinicians' authority. This paper draws upon narratives from patients in the United Kingdom (UK) who have access to their EHRs and suggests strategies for moving beyond these controversies between proponents and critics of the system. It additionally shows that the very organizational, procedural, and technological infrastructure that promises patients' increased access to records can also exacerbate some patients' "difficult" behaviors. © 2017 American Medical Association.

Moods as spotlights: the influence of mood on accessibility effects.
Avramova, Yana R; Stapel, Diederik A
2008-09-01
Three studies explore the manner in which one's mood may affect the use and impact of accessible information on judgments. Specifically, the authors demonstrated that positive and negative moods differentially influence the direction of accessibility effects (assimilation, contrast) by determining whether abstract traits or concrete actor-trait links are primed. Study 1 investigated the impact of positive versus negative mood on the judgmental impact of trait-implying behaviors and found that positive moods lead to assimilation and negative moods to contrast. In Study 2, this effect was replicated in a subliminal priming paradigm. In Study 3, it was demonstrated that the type of information activated by trait-implying behaviors is indeed mood dependent, such that abstract trait information is activated in a positive mood, whereas specific actor-trait links are activated in a negative mood.

Objective To describe a simple, novel method to achieve ureteric access in the Cohen crossed reimplanted ureter, which will allow retrograde working access via the conventional transurethral method. Materials and Methods Under cystoscopic vision, suprapubic needle puncture was performed. The needle was directed (bevel facing) towards the desired ureteric orifice (UO). A guidewire (with a floppy-tip) was then inserted into the suprapubic needle passing into the bladder, and then easily passed into the crossed-reimplanted UO. The distal end of the guidewire was then removed through the urethra with cystoscopic grasping forceps. The straightened ureter then easily facilitated ureteroscopy access, retrograde pyelogram studies, and JJ stent insertion in a conventional transurethral method. Results The UO and ureter were aligned in a more conventional orthotopic course, to allow for conventional transurethral working access. Conclusion A novel method to access the Cohen crossed reimplanted ureter was described. All previously published methods of accessing the crossed ureter were critically appraised. PMID:29463976

Security and privacy in electronic health records: a systematic literature review.
Fernández-Alemán, José Luis; Señor, Inmaculada Carrión; Lozoya, Pedro Ángel Oliver; Toval, Ambrosio
2013-06-01
To report the results of a systematic literature review concerning the security and privacy of electronic health record (EHR) systems. Original articles written in English found in MEDLINE, ACM Digital Library, Wiley InterScience, IEEE Digital Library, Science@Direct, MetaPress, ERIC, CINAHL and Trip Database. Only those articles dealing with the security and privacy of EHR systems. The extraction of 775 articles using a predefined search string, the outcome of which was reviewed by three authors and checked by a fourth. A total of 49 articles were selected, of which 26 used standards or regulations related to the privacy and security of EHR data. The most widely used regulations are the Health Insurance Portability and Accountability Act (HIPAA) and the European Data Protection Directive 95/46/EC. We found 23 articles that used symmetric key and/or asymmetric key schemes and 13 articles that employed the pseudo anonymity technique in EHR systems. A total of 11 articles propose the use of a digital signature scheme based on PKI (Public Key Infrastructure) and 13 articles propose a login/password (seven of them combined with a digital certificate or PIN) for authentication. The preferred access control model appears to be Role-Based Access Control (RBAC), since it is used in 27 studies. Ten of these studies discuss who should define the EHR systems' roles. Eleven studies discuss who should provide access to EHR data: patients or health entities. Sixteen of the articles reviewed indicate that it is necessary to override defined access policies in the case of an emergency. In 25 articles an audit-log of the system is produced. Only four studies mention that system users and/or health staff should be trained in security and privacy. Recent years have witnessed the design of standards and the promulgation of directives concerning security and privacy in EHR systems. However, more work should be done to adopt these regulations and to deploy secure EHR systems. Copyright © 2013 Elsevier Inc. All rights reserved.

EU accession: A policy window opportunity for nursing?
De Raeve, Paul; Rafferty, Anne-Marie; Bariball, Louise; Young, Ruth; Boiko, Olga
2017-03-01
European enlargement has been studied in a wide range of policy areas within and beyond health. Yet the impact of EU enlargement upon one of the largest health professions, nursing, has been largely neglected. This paper aims to explore nurse leadership using a comparative case study method in two former Communist countries, Romania and Croatia. Specifically, it considers the extent to which engagement in the EU accession policy-making process provided a policy window for the leaders to formulate and implement a professional agenda while negotiating EU accession. Findings of qualitative interviews and documentary analysis indicate that the mechanisms used to facilitate the accession process were not successful in achieving compliance with the education standards in the Community Acquis, as highlighted in the criteria on the mutual recognition of professional qualifications set out in Directive 2005/36/EC. EU accession capacity building and accession funds were not deployed efficiently to upgrade Romanian and Croatian nursing education towards meeting EU standards. Conflicting views on accession held by the various nursing stakeholders (nursing regulator, nursing union, governmental chief nurse and the professional association) inhibited the setting of a common policy agenda to achieve compliance with EU standards. The study findings suggest a need to critically review EU accession mechanisms and better align leadership at all governance levels. Copyright © 2017 Elsevier B.V. All rights reserved.

The Jet Propulsion Laboratory is exploring the potential and feasibility of a personal access satellite system (PASS) that will offer the user greater freedom and mobility than existing or currently planned communications systems. Studies performed in prior years resulted in a strawman design and the identification of technologies that are critical to the successful implementation of PASS. The study efforts in FY-89 were directed towards alternative design options with the objective of either improving the system performance or alleviating the constraints on the user terminal. The various design options and system issues studied this year and the results of the study are presented.

Older teen attitudes toward birth control access in pharmacies: a qualitative study.
Wilkinson, Tracey A; Miller, Courtney; Rafie, Samantha; Landau, Sharon Cohen; Rafie, Sally
2018-03-01
To examine adolescent attitudes toward accessing contraception through a new pharmacist prescribing model in the State of California. In-depth telephone interviews were conducted in summer 2015 with 30 females ages 18 to 19 in California. Participants were recruited using a social media advertisement. Semi-structured interviews utilized open-ended questions to understand teens' experiences with pharmacies, experiences obtaining contraception, and views on pharmacist prescribing of contraception. Responses were transcribed and qualitatively analyzed using an independent-coder method to identify salient themes. Participants were ethnically diverse and primarily living in suburban areas. All participants had completed high school and many had completed one year of college. Nearly all participants were supportive of California's new law allowing pharmacist prescribing of contraception. Thematic analyses revealed that while participants were satisfied with traditional service providers and valued those relationships, they appreciated the benefit of increased access and convenience of going directly to a pharmacy. Participants expected increased access to contraception in pharmacies would lead to both personal and societal benefits. They expressed concerns regarding parental involvement, as well as confidentiality in the pharmacy environment and with insurance disclosures. Older teens in California are very supportive of pharmacies and pharmacists as direct access points for contraception, but confidentiality concerns were noted. Policy makers and pharmacies can incorporate study findings when designing policies, services, and physical pharmacy spaces to better serve teens. Further research is warranted after pharmacies implement this new service to assess teen utilization and satisfaction as well as outcomes. Several states recently passed legislation enabling pharmacists to prescribe contraception and other states are considering similar legislation. Older teens are interested in this additional method of contraceptive access and understanding their perspectives can help guide implementation by states and in individual pharmacies.

Finance issue brief: direct access: year end report-2002.
Morgan, Rachel; MacEachern, Lillian
2002-12-31
Consumer demand for a less restrictive referral system has urged legislators, as well as the managed care industry and those in the medical field, to seek the best solution to the problem. The point of service (POS) plan was an early attempt by managed care plans to provide more freedom for enrollees. But POS plans are not always available or cost effective. Several of the larger managed care organizations, in an effort to improve enrollee and provider satisfaction, have eliminated or streamlined their referral processes. The American Medical Association has recommended that primary care and other medical specialty organizations collaborate in developing guidelines for specialty referrals, urging health plans to allow direct access in network without financial penalty as long as the access conforms with the established guidelines. In the meantime, legislators have responded to constituents by enacting measures that mandate direct access for specific types of care or standing referrals for ongoing treatment.

As per American Heart Association/American College of Cardiology guidelines, the delay between first medical contact and balloon inflation should not exceed 90 min for primary percutaneous coronary intervention (PCI). In North America, few prehospital systems have been developed to grant rural populations timely access to PCI. The objective of the present study was to evaluate the ability of an ST-segment elevation myocardial infarction (STEMI) system serving suburban and rural populations to achieve the recommended 90-min interval benchmark for PCI. A prehospital telemedicine program was implemented in a rural and suburban region of the Quebec province. Three patient groups with STEMI were created according to trajectory: 1) patients already en route to a PCI center, 2) patients initially directed to the nearest hospital who were subsequently diverted to a PCI center during transport, and 3) patients directed to the nearest hospital without transfer for PCI. Time intervals were compared across groups. Of the 208 patients diagnosed with STEMI, 14.9% were already on their way to a hospital with PCI capabilities, 75.0% were rerouted to a PCI center, and 10.1% were directed to the nearest local hospital. All patients but one arrived at the PCI center within the 60-min prehospital care interval, considering an additional 30 min for balloon inflation at the PCI center. This study demonstrated that a regionalized prehospital system for STEMI patients could achieve the recommended 90-min interval benchmark for PCI, while giving timely access to PCI to rural populations that would not otherwise have access to this treatment.

The rollout of antiretroviral therapy (ART) significantly reduced human immunodeficiency virus (HIV)-related morbidity and mortality, but good clinical outcomes depend on access and adherence to treatment. In resource-limited settings, where over 90% of the world’s HIV-infected population resides, data on barriers to treatment are emerging that contribute to low rates of uptake in HIV testing, linkage to and retention in HIV care systems, and suboptimal adherence rates to therapy. A review of the literature reveals limited evidence to inform strategies to improve access and adherence with the majority of studies from sub-Saharan Africa. Data from observational studies and randomized controlled trials support home-based, mobile and antenatal care HIV testing, task-shifting from doctor-based to nurse-based and lower level provider care, and adherence support through education, counseling and mobile phone messaging services. Strategies with more limited evidence include targeted HIV testing for couples and family members of ART patients, decentralization of HIV care, including through home- and community-based ART programs, and adherence promotion through peer health workers, treatment supporters, and directly observed therapy. There is little evidence for improving access and adherence among vulnerable groups such as women, children and adolescents, and other high-risk populations and for addressing major barriers. Overall, studies are few in number and suffer from methodological issues. Recommendations for further research include health information technology, social-level factors like HIV stigma, and new research directions in cost-effectiveness, operations, and implementation. Findings from this review make a compelling case for more data to guide strategies to improve access and adherence to treatment in resource-limited settings. PMID:23326204

The Uses of the Smartphone for Doctors: An Empirical Study from Samsung Medical Center
Choi, Jong Soo; Yi, Byoungkee; Park, Jong Hwan; Choi, Kyesook; Jung, Jaegon; Park, Seung Woo
2011-01-01
Objectives In healthcare, mobile computing made possible by smartphones is becoming an important tool among healthcare professionals. However, currently there is very little research into the effectiveness of such applications of technology. This study aims to present a framework for a smartphone application to give doctors mobile access to patient information, then review the consequences of its use and discuss its future direction. Methods Since 2003 when Samsung Medical Center introduced its first mobile application, a need to develop a new application targeting the latest smartphone technology was identified. To that end, an application named Dr. SMART S was officially launched on December 22nd, 2010. Results We analyzed the usage data of the application for a month until April 25th, 2011. On average, 170 doctors (13% of the entire body of doctors) logged on 2.4 times per day and that number keeps growing. The number was uniformly distributed across all working hours, with exceptions of heavy accesses around 6-8 AM and 4-6 PM when doctors do their regular rounds to see the patients. The most commonly accessed content was inpatient information, this constituted 78.6% of all accesses, within this 50% was to accesses lab results. Conclusions Looking at the usage data, we can see the use of Dr. SMART S by doctors is growing in sync with the popularity of smartphones. Since u-Health seem an inevitable future trend, a more rigorous study needs to be conducted on how such mobile applications as Dr. SMART S affect the quality of care and patient safety to derive directions for further improvements.

[Stents in dialysis vascular access--do they promise improved high quality prolonged access use].
Klein, Osnat; Plotkin, Eleonora; Gritun, Igal; Verner, Myriam; Lehmann, J M; Rathaus, Mauro; Bernheim, Jacques
2008-02-01
The life expectancy of dialysis patients depends, to a large extent, on blood access which provides uninterrupted and efficient treatment. Dialysis access created by a direct anastomosis between artery and vein usually allows normal dialysis for many years. Blood access by a bridge graft between artery and vein functions for a much shorter time and occludes chiefly because of endothelial hyperplasia at the graft vein anastomosis. This type of fistula is created when the veins of the patient are small. During the last few years the dialysis population is increasingly composed of adult and elderly patients suffering from diabetes mellitus, hypertension, dyslipidemias and atheromatous vascular disease so that a relatively large proportion of dialysis accesses are created using a bridge graft. Since we currently do not have the knowledge of how to arrest or delay the processes which lead to access occlusion, attempts are made to implement prophylactic strategies, find stenoses and dilate them before the access fails. Up to date, controlled trials have not succeeded in proving that this method prolongs access use. These trials did not describe the use of stents following dilatation. Between July 2002 and May 2005, 238 angiographies were performed on blood accesses including 179 angioplasties of stenoses. In sixteen patients a stent was deployed during the angioplasty. In ten patients dialysis was performed using the same access up to the end of the study period, an average of 43 months from the creation of the access. Three patients died with a functioning access and in three the access occluded during the period of followup. This study shows that the use of stents following angioplasty of dialysis access stenoses can improve the duration of use of accesses created through grafts.

There are constraints embedded in medical record structure that limit use by patients in self-directed disease management. Through systematic review of the literature from a critical perspective, four characteristics that either enhance or mitigate the influence of medical record structure on patient utilization of an electronic patient record (EPR) system have been identified: environmental pressures, physician centeredness, collaborative organizational culture, and patient centeredness. An evaluation framework is proposed for use when considering adaptation of existing EPR systems for online patient access. Exemplars of patient-accessible EPR systems from the literature are evaluated utilizing the framework. From this study, it appears that traditional information system research and development methods may not wholly capture many pertinent social issues that arise when expanding access of EPR systems to patients. Critically rooted methods such as action research can directly inform development strategies so that these systems may positively influence health outcomes. PMID:14633932

The aim of this scoping review was to uncover and summarize what is known in the literature about the experiences of Indigenous women in Asia regarding access to health services. The study was informed by the scoping review methodology proposed by Arksey and O'Malley [2005. "Scoping Studies: Towards a Methodological Framework." International Journal of Social Research Methodology 8 (1): 19-32. doi: 10.1080/1364557032000119616 ]. A comprehensive search of the databases for peer-reviewed studies and grey literature was conducted between January 2000 and December 2016. The data of selected papers and abstracts were analysed by three independent researchers through a protocol of data charting, descriptive numerical summary, and thematic analysis. Sixteen articles and two abstracts met the inclusion criteria for this scoping review. These 18 peer-reviewed documents consisted of eight qualitative studies, seven quantitative studies, and three mixed-method studies, which included the peer-reviewed poster and oral presentation abstracts from international conferences. The findings were sorted and grouped under the following themes: health care access for Indigenous women in Asia, facilitators to accessing healthcare services, barriers to accessing healthcare services, and cultural contexts impacting health and access. There is limited information about the experiences, facilitators, barriers, and cultural contexts faced by Indigenous women in Asia related to health services accessibility, and even less information related to improving health services accessibility and health outcomes. This scoping review in particular highlights the dearth of literature relating to Indigenous women's postpartum health and access to postnatal supports and services. Generally, it indicates that Indigenous women in Asia are more vulnerable to poor health in comparison to non-Indigenous women, and continue to face challenges and barriers in accessing quality and equitable health services. The barriers identified in this review are useful in explaining why inequities in health and access to health care for Indigenous women living in Asia continue to exist. Recommendations for future research directions are described.

How to Assess Data Availability, Accessibility and Format for Risk Analysis?
Humblet, M-F; Vandeputte, S; Mignot, C; Bellet, C; De Koeijer, A; Swanenburg, M; Afonso, A; Sanaa, M; Saegerman, C

Risk assessments are mostly carried out based on available data, which do not reflect all data theoretically required by experts to answer them. This study aimed at developing a methodology to assess data availability, accessibility and format, based on a scoring system and focusing on two diseases: Venezuelan equine encephalomyelitis (VEE), still exotic to Europe, and alveolar echinococcosis, caused by Echinococcus multilocularis (EM), endemic in several Member States (MSs). After reviewing 36 opinions of the EFSA-AHAW Panel on risk assessment of animal health questions, a generic list of needed data was elaborated. The methodology consisted, first, in implementing a direct and an indirect survey to collect the data needed for both case studies: the direct survey consisted in a questionnaire sent to contact points of three European MSs (Belgium, France and the Netherlands), and the organization of a workshop gathering experts on both diseases. The indirect survey, focusing on the three MSs involved in the direct survey plus Spain, relied on web searches. Secondly, a scoring system with reference to data availability, accessibility and format was elaborated, to, finally, compare both diseases and data between MSs. The accessibility of data was generally related to their availability. Web searches resulted in more data available for VEE compared to EM, despite its current exotic status in the European Union. Hypertext markup language and portable document files were the main formats of available data. Data availability, accessibility and format should be improved for research scientists/assessors. The format of data plays a key role in the feasibility and rapidness of data management and analysis, through a prompt compilation, combination and aggregation in working databases. Harmonization of data collection process is encouraged, according to standardized procedures, to provide useful and reliable data, both at the national and the international levels for both animal and human health; it would allow assessing data gaps through comparative studies. The present methodology is a good way of assessing the relevance of data for risk assessment, as it allows integrating the uncertainty linked to the quality of data used. Such an approach could be described as transparent and traceable and should be performed systematically. © 2015 Blackwell Verlag GmbH.

Wechsler Adult Intelligence Scale (WAIS) subscale Similarities have been classified as a test of either verbal comprehension or of inductive reasoning. The reason may be that items divide into two categories. We tested the hypothesis of heterogeneity of items in WAIS-Similarities. Consecutive patients at a memory clinic and healthy controls participated in the study. White-matter hyperintensities (WMHs) and normalized temporal lobe volumes were measured based on Magnetic resonance Imaging (MRI), and tests of verbal memory and attention were used in addition to WAIS-Similarities to collect behavioural data. Factor analysis supported the hypothesis that two factors are involved in the performance of WAIS-similarities: (1) semiautomatic lexical access and (2) conceptual elaboration. These factors were highly correlated but provided discriminative diagnostic information: In logistic regression analyses, scores of the lexical access factor and of the conceptual elaboration factor discriminated patients with mild cognitive impairment from Alzheimer's disease patients and from healthy controls, respectively. High scores of WMH, indicating periventricular white-matter lesions, predicted factor scores of direct lexical access but not those of conceptual elaboration, which were predicted only by medial and lateral temporal lobe volumes.

Policy dialogues are critical for developing responsive, effective, sustainable, evidence-informed policy. Our multidisciplinary team, including researchers, physicians and senior decision-makers, comprehensively evaluated The Winnipeg Central Intake Service, a single-entry model in Winnipeg, Manitoba, to improve patient access to hip/knee replacement surgery. We used the evaluation findings to develop five evidence-informed policy directions to help improve access to scheduled clinical services across Manitoba. Using guiding principles of public participation processes, we hosted a policy roundtable meeting to engage stakeholders and use their input to refine the policy directions. Here, we report on the use and input of a policy roundtable meeting and its role in contributing to the development of evidence-informed policy. Our evidence-informed policy directions focused on formal measurement/monitoring of quality, central intake as a preferred model for service delivery, provincial scope, transparent processes/performance indicators, and patient choice of provider. We held a policy roundtable meeting and used outcomes of facilitated discussions to refine these directions. Individuals from our team and six stakeholder groups across Manitoba participated (n = 44), including patients, family physicians, orthopaedic surgeons, surgical office assistants, Winnipeg Central Intake team, and administrators/managers. We developed evaluation forms to assess the meeting process, and collected decision-maker partners' perspectives on the value of the policy roundtable meeting and use of policy directions to improve access to scheduled clinical services after the meeting, and again 15 months later. We analyzed roundtable and evaluation data using thematic analysis to identify key themes. Four key findings emerged. First, participants supported all policy directions, with revisions and key implementation considerations identified. Second, participants felt the policy roundtable meeting achieved its purpose (to engage stakeholders, elicit feedback, refine policy directions). Third, our decision-maker partners' expectations of the policy roundtable meeting were exceeded; they re-affirmed its value and described the refined policy directions as foundational to establishing the vocabulary, vision and framework for improving access to scheduled clinical services in Manitoba. Finally, our adaptation of key design elements was conducive to discussion of issues surrounding access to care. Our policy roundtable process was an effective tool for acquiring broad input from stakeholders, refining policy directions and forming the necessary consensus starting points to move towards evidence-informed policy.

Truck Drivers' Use of the Internet: A Mobile Health Lifeline.
Heaton, Karen; Combs, Bryan; Griffin, Russell
2017-06-01
Because of their social isolation, irregular and unpredictable schedules, limited access to health care, and long periods of travel, long-haul truckers may benefit from the use of mobile health applications on Internet-capable devices. The purpose of this study was to determine Internet access and usage among a sample of long-haul truck drivers. In this cross-sectional study, truck drivers completed a pencil and paper survey with questions on demographics, work and health histories, and Internet access and usage for both personal and job reasons. A total of 106 truck drivers were recruited from trucking industry trade shows, by word of mouth, and directly from trucking companies. Overall, the truck drivers' use of the Internet was limited. Their usage for personal and job-related reasons differed. Social connectivity and access to health and wellness information were important during personal usage time. Job-related Internet use was highly practical, and applied to seeking information for directions and maps, fuel stops and pricing, and communicating with employers or transmitting documents. Age and experience were associated with Internet use. Younger, less-experienced drivers used the Internet more than older, experienced drivers. Targeted mobile health messaging may be a useful tool to inform truck drivers of health conditions and plans, and may provide links to primary care providers needing to monitor or notify drivers of diagnostic results or treatment plans.

Rationale and Objectives Inefficient transfer of personal health records among providers negatively impacts quality of health care and increases cost. This multicenter study evaluates the implementation of the first Internet-based image-sharing system that gives patients ownership and control of their imaging exams, including assessment of patient satisfaction. Materials and Methods Patients receiving any medical imaging exams in four academic centers were eligible to have images uploaded into an online, Internet-based personal health record. Satisfaction surveys were provided during recruitment with questions on ease of use, privacy and security, and timeliness of access to images. Responses were rated on a five-point scale and compared using logistic regression and McNemar's test. Results A total of 2562 patients enrolled from July 2012 to August 2013. The median number of imaging exams uploaded per patient was 5. Most commonly, exams were plain X-rays (34.7%), computed tomography (25.7%), and magnetic resonance imaging (16.1%). Of 502 (19.6%) patient surveys returned, 448 indicated the method of image sharing (Internet, compact discs [CDs], both, other). Nearly all patients (96.5%) responded favorably to having direct access to images, and 78% reported viewing their medical images independently. There was no difference between Internet and CD users in satisfaction with privacy and security and timeliness of access to medical images. A greater percentage of Internet users compared to CD users reported access without difficulty (88.3% vs. 77.5%, P < 0.0001). Conclusion A patient-directed, interoperable, Internet-based image-sharing system is feasible and surpasses the use of CDs with respect to accessibility of imaging exams while generating similar satisfaction with respect to privacy.

Background: Enhanced quality of care and improved access are central to effective primary care management of long term conditions. However, research evidence is inconclusive in establishing a link between quality of primary care, or access, and adverse outcomes, such as unplanned hospitalisation. Methods: This paper proposes a structural equation model for quality and access as latent variables affecting adverse outcomes, such as unplanned hospitalisations. In a case study application, quality of care (QOC) is defined in relation to diabetes, and the aim is to assess impacts of care quality and access on unplanned hospital admissions for diabetes, while allowing also for socio-economic deprivation, diabetes morbidity, and supply effects. The study involves 90 general practitioner (GP) practices in two London Clinical Commissioning Groups, using clinical quality of care indicators, and patient survey data on perceived access. Results: As a single predictor, quality of care has a significant negative impact on emergency admissions, and this significant effect remains when socio-economic deprivation and morbidity are allowed. In a full structural equation model including access, the probability that QOC negatively impacts on unplanned admissions exceeds 0.9. Furthermore, poor access is linked to deprivation, diminished QOC, and larger list sizes. Conclusions: Using a Bayesian inference methodology, the evidence from the analysis is weighted towards negative impacts of higher primary care quality and improved access on unplanned admissions. The methodology of the paper is potentially applicable to other long term conditions, and relevant when care quality and access cannot be measured directly and are better regarded as latent variables.

A DTN-Based Multiple Access Fast Forward Service for the NASA Space Network
NASA Technical Reports Server (NTRS)
Israel, David; Davis, Faith; Marquart. Jane
2011-01-01
The NASA Space Network provides a demand access return link service capable of providing users a space link "on demand". An equivalent service in the forward link direction is not possible due to Tracking and Data Relay Spacecraft (TDRS) constraints. A Disruption Tolerant Networking (DTN)-based Multiple Access Fast Forward (MAFF) service has been proposed to provide a forward link to a user as soon as possible. Previous concept studies have identified a basic architecture and implementation approach. This paper reviews the user scenarios and benefits of an MAFF service and proposes an implementation approach based on the use of DTN protocols.

Sexually transmitted infections (STIs) are widespread in the United States among people ages 15-24 years and cost almost $16 billion yearly. It is therefore important to understand message design strategies that could help reduce these numbers. Guided by exemplification theory and the extended parallel process model (EPPM), this study examines the influence of message format and the presence versus absence of a graphic image on recipients' accessibility of STI attitudes regarding safe sex. Results of the experiment indicate a significant effect from testimonial messages on increased attitude accessibility regarding STIs compared to statistical messages. Results also indicate a conditional indirect effect of testimonial messages on STI attitude accessibility, though threat is greater when a graphic image is included. Implications and directions for future research are discussed.

Healthcare barriers of refugees post-resettlement.
Morris, Meghan D; Popper, Steve T; Rodwell, Timothy C; Brodine, Stephanie K; Brouwer, Kimberly C
2009-12-01
The majority of refugees spend the greater part of their lives in refugee camps before repatriation or resettlement to a host country. Limited resources and stress during residence in refugee camps can lead to a variety of acute and chronic diseases which often persist upon resettlement. However, for most resettled refugees little is known about their health needs beyond a health assessment completed upon entry. We conducted a qualitative pilot-study in San Diego County, the third largest area in California, USA for resettling refugees, to explore health care access issues of refugees after governmental assistance has ended. A total of 40 guided in-depth interviews were conducted with a targeted sample of informants (health care practitioners, employees of refugee serving organizations, and recent refugee arrivals) familiar with the health needs of refugees. Interviews revealed that the majority of refugees do not regularly access health services. Beyond individual issues, emerging themes indicated that language and communication affect all stages of health care access--from making an appointment to filling out a prescription. Acculturation presented increased stress, isolation, and new responsibilities. Additionally, cultural beliefs about health care directly affected refugees' expectation of care. These barriers contribute to delayed care and may directly influence refugee short- and long-term health. Our findings suggest the need for additional research into contextual factors surrounding health care access barriers, and the best avenues to reduce such barriers and facilitate access to existing services.

A widespread family of methods for studying and predicting protein interactions using sequence information is based on co-evolution, quantified as similarity of phylogenetic trees. Part of the co-evolution observed between interacting proteins could be due to co-adaptation caused by inter-protein contacts. In this case, the co-evolution is expected to be more evident when evaluated on the surface of the proteins or the internal layers close to it. In this work we study the effect of incorporating information on predicted solvent accessibility to three methods for predicting protein interactions based on similarity of phylogenetic trees. We evaluate the performance of these methods in predicting different types of protein associations when trees based on positions with different characteristics of predicted accessibility are used as input. We found that predicted accessibility improves the results of two recent versions of the mirrortree methodology in predicting direct binary physical interactions, while it neither improves these methods, nor the original mirrortree method, in predicting other types of interactions. That improvement comes at no cost in terms of applicability since accessibility can be predicted for any sequence. We also found that predictions of protein-protein interactions are improved when multiple sequence alignments with a richer representation of sequences (including paralogs) are incorporated in the accessibility prediction.

This cross-sectional study examined the direct and indirect effects of perceived equipment accessibility, neighborhood safety, and social support on self-reported physical activity among older adolescent girls. Adolescent girls (n = 1,655) who were in the 12th grade completed a battery of questionnaires that included self-report measures of the perceived physical environment, social support, barriers self-efficacy, and physical activity. Perceived neighborhood safety did not exhibit direct or indirect effects on self-reported physical activity. Perceived equipment accessibility exhibited an indirect effect on self-reported physical activity that was accounted for by barriers self-efficacy. Perceived social support exhibited direct and indirect effects on self-reported physical activity; the indirect effect was accounted for by barriers self-efficacy. The relationships were independent of parental education and body mass index (BMI). Perceived physical environmental factors indirectly influenced self-reported physical activity, and perceived social environmental factors both directly and indirectly influenced self-reported physical activity in this sample of older adolescent girls.

Interest in a digital health tool in veterans with epilepsy: results of a phone survey.
Hixson, John D; Van Bebber, Stephanie L; Bertko, Kate M
2015-04-01
Online tools for managing chronic health conditions are becoming increasingly popular. Perceived benefits include ease of use, low costs, and availability but are contingent on patient engagement, Internet access, and digital literacy. This article describes data collected during the recruitment phase of a study evaluating an online self-management platform for epilepsy in a U.S. Veteran population. We used administrative data to identify and contact Veterans with a likely diagnosis of epilepsy in the Veterans Health Administration (VHA). Veterans who did not respond directly to a mailed invitation were recruited by phone to determine study interest and evaluate digital access. Of the 2,143 Veterans mailed study invitations, phone calls were made to 1,789 who did not specifically decline participation. Among those reached by phone (n = 1,053): 295 (28%) expressed interest in the study and an online tool, 333 (19%) reported a lack of computer and/or Internet access and 425 (40%) were not interested for other reasons. This study suggests an interest in online tools for managing health despite the fact that some Veterans lack computer and/or Internet access. As investment in digital health solutions grows, the VHA should prioritize the widespread provision of digital access to more Veterans.

How Does Organisational Literacy Impact Access to Health Care for Homeless Individuals?
Hughes, Naomi Rebecca
2017-03-01
This article describes a study that examined the experiences of 27 individuals who frequented an Open Access homeless shelter in Toronto, Canada. The overarching aim of this study was to map the social organisation of health care in Toronto, with particular regards to the ways in which literacy, or the lack of literacy, mediates the experiences of homeless individuals attempting to gain access to health care. While terms such as "literate" or "illiterate" might be seen to reflect an individual's level of acquired education or competence, critical social theorists argue that such terms instead more accurately reflect an individual's relative class or position within the social hierarchy. Individuals who possess literacy are able to read into texts for their implicit understandings, directives, and power structures. Furthermore, they are able to translate and decode texts as potential pretexts for coordination or control. This study draws on a Freirean critical standpoint, which acknowledges that knowledge and power are inextricably interconnected. This study asked: How does literacy, or the lack of literacy, facilitate or impede access to health care for homeless individuals? What are the social consequences of illiteracy?

A mission concept study to define the "Advanced Cosmic-ray Composition Experiment for Space Station (ACCESS)" was sponsored by the National Aeronautics and Space Administration (NASA). The ACCESS instrument complement contains a transition radiation detector and an ionization calorimeter to measure tile spectrum of protons, helium, and heavier nuclei up to approximately 10(exp 15) eV to search for the limit of S/N shock wave acceleration, or evidence for other explanations of the spectra. Several calorimeter configurations have been studied, including the "baseline" totally active bismuth germanate instrument and sampling calorimeters utilizing various detectors. The Imaging Calorimeter for ACCESS (ICA) concept comprises a carbon target and a calorimeter using a high atomic number absorber sampled approximately each radiation length (rl) by thin scintillating fiber (SCIFI) detectors. The main features and options of the ICA instrument configuration are described in this paper. Since direct calibration is not possible over most of the energy range, the best approach must be decided from simulations of calorimeter performance extrapolated from CERN calibrations at 0.375 TeV. This paper presents results from the ICA simulations study.

Radiative electron capture, the time-reversed photoionization process occurring in ion-atom collisions, provides presently the only access to photoionization studies for very highly charged ions. By applying the deceleration mode of the ESR storage ring, we studied this process in low-energy collisions of bare uranium ions with low- Z target atoms. This technique allows us to extend the current information about photoionization to much lower energies than those accessible for neutral heavy elements in the direct reaction channel. The results prove that for high- Z systems, higher-order multipole contributions and magnetic corrections persist even at energies close to the threshold.

Accessible Earth: Enhancing diversity in the Geosciences through accessible course design
NASA Astrophysics Data System (ADS)
Bennett, R. A.; Lamb, D. A.
2017-12-01
The tradition of field-based instruction in the geoscience curriculum, which culminates in a capstone geological field camp, presents an insurmountable barrier to many disabled students who might otherwise choose to pursue geoscience careers. There is a widespread perception that success as a practicing geoscientist requires direct access to outcrops and vantage points available only to those able to traverse inaccessible terrain. Yet many modern geoscience activities are based on remotely sensed geophysical data, data analysis, and computation that take place entirely from within the laboratory. To challenge the perception of geoscience as a career option only for the non-disabled, we have created the capstone Accessible Earth Study Abroad Program, an alternative to geologic field camp for all students, with a focus on modern geophysical observation systems, computational thinking, data science, and professional development.In this presentation, we will review common pedagogical approaches in geosciences and current efforts to make the field more inclusive. We will review curricular access and inclusivity relative to a wide range of learners and provide examples of accessible course design based on our experiences in teaching a study abroad course in central Italy, and our plans for ongoing assessment, refinement, and dissemination of the effectiveness of our efforts.

The 3-year survival after small bowel transplantation (SBTx) has improved to between 73% and 88%. Impaired venous access for parenteral nutrition can be an indication for SBTx in children with chronic intestinal failure. To report our experience in management of children with extreme end-stage venous access. The study consisted of 6 children (all boys), median age of assessment 27 months (range, 13-52 months), diagnosed with total intestinal aganglionosis (1), protracted diarrhea (1), and short bowel syndrome (4), of which gastroschisis (2) and malrotation with midgut volvulus (2) were the causes. All had a documented history of more than 10 central venous catheter insertions previously. All had venograms, and 1 child additionally had a magnetic resonance angiogram to evaluate venous access. Five of 6 presented with thrombosis of the superior vena cava (SVC) and/or inferior vena cava. Venous access was reestablished as follows: transhepatic venous catheters (5), direct intra-atrial catheter via midline sternotomy (4), azygous venous catheters (2), dilatation of left subclavian vein after passage of a guide wire and then placing a catheter to reach the right atrium (1), radiological recanalization of the SVC and placement of a central venous catheter in situ (1), and direct puncture of SVC stump(1). Complications included serous pleural effusion after direct intra-atrial line insertion, which resolved after chest drain insertion (1), displacement of transhepatic catheter needing repositioning (2), and SVC stent narrowing requiring repeated balloon dilatation. Four children with permanent intestinal failure on assessment were offered SBTx, 3 of which were transplanted and were established on full enteral nutrition; the family of 1 child declined the procedure. In the remaining 2 children in whom bowel adaptation was still a possibility, attempts were made to provide adequate central venous access as feeds and drug manipulations were undertaken. One of them received liver and SBTx nearly 3 years after presenting with end-stage central venous access, because attempts to achieve independence from parenteral nutrition had failed. The other child died immediately after a transhepatic venous catheter placement, possibly from a nutritional depletion syndrome as no physical cause of death was found. Direct intra-atrial catheters in transplanted children proved to be adequate for the management of uncomplicated transplantation, although the usual infusion protocol had to be modified considerably, and the lack of access would have been critical if massive blood transfusion had been required during the transplant procedure. It was possible to reestablish central venous access in all cases. However, this was time consuming and difficult to assemble a skilled team consisting of one of more: surgeon, cardiologist, interventional radiologist, and transplant anesthetist. Small bowel transplantation is easier and safer with adequate central venous access, and we advocate liaison with an SBTx center at an early stage.

To improve informed medical decision-making, principles for family-centered neonatal care recommend that parents have access to their child's medical record on an ongoing basis during neonatal intensive unit care (NICU) hospitalization. Currently, many NICUs do not allow independent parent access to their child's electronic medical record (EMR) during hospitalization. We undertook a cross-sectional survey pilot study of medical professionals and parents to explore opinions regarding this practice. Inclusion criteria: 18-years old, English-literate, legal guardian of patients admitted to the NICU for 14 days. NICU medical professionals included physicians, nurse practitioners, nurses, and respiratory therapists. Medical professionals believed parent access would make their work more difficult, increase time documenting and updating families, making them more liable to litigation and hesitant to chart sensitive information. However, parents felt that they lacked control over their child's care and desired direct access to the EMR. Parents believed this would improve accuracy of their child's medical chart, and increase advocacy and understanding of their child's illness. NICU parents and medical professionals have differing perspectives on independent parental access to their child's EMR. More research is needed to explore the potential of independent parental EMR access to further improve family-centered neonatal care.

Distributed multiport memory architecture

Kohl, W. H. (Inventor)
1983-01-01
A multiport memory architecture is diclosed for each of a plurality of task centers connected to a command and data bus. Each task center, includes a memory and a plurality of devices which request direct memory access as needed. The memory includes an internal data bus and an internal address bus to which the devices are connected, and direct timing and control logic comprised of a 10-state ring counter for allocating memory devices by enabling AND gates connected to the request signal lines of the devices. The outputs of AND gates connected to the same device are combined by OR gates to form an acknowledgement signal that enables the devices to address the memory during the next clock period. The length of the ring counter may be effectively lengthened to any multiple of ten to allow for more direct memory access intervals in one repetitive sequence. One device is a network bus adapter which serially shifts onto the command and data bus, a data word (8 bits plus control and parity bits) during the next ten direct memory access intervals after it has been granted access. The NBA is therefore allocated only one access in every ten intervals, which is a predetermined interval for all centers. The ring counters of all centers are periodically synchronized by DMA SYNC signal to assure that all NBAs be able to function in synchronism for data transfer from one center to another.

According to terror management theory, if the cultural worldview protects people from thoughts about death, then weakening this structure should increase death-thought accessibility (DTA). Five studies tested this DTA hypothesis. Study 1 showed that threatening Canadian participants' cultural values (vs. those of another culture) increased DTA on a word-fragment completion task. Study 2 showed that when participants could dismiss the threat, DTA remained low. Study 3 replicated the results of Study 1, but DTA was measured using a lexical decision task. Response latencies to death, negative, and neutral content were measured. Worldview threat increased DTA relative to accessibility for negative and neutral content. Study 4 showed that the DTA effect emerged independently of the arousal of anger or anxiety. Finally, Study 5 demonstrated that participants with a pro-creation (vs. pro-evolution) worldview had higher DTA after reading an anti-creation article. Discussion focused on theoretical implications and directions for further research. ((c) 2007 APA, all rights reserved).

In a primary health-care centre (PHCC) situated in a segregated area with low socio-economic status, 'primary care triage' has increased efficiency and accessibility. In the primary-care triage, the nurse sorts the patient to the appropriate PHCC profession according to described symptoms. Aim The aim of this study was to examine the patients' experience of being triaged directly to a psychologist for assessment. Interviews were conducted with 20 patients and then analysed using qualitative content analysis. The results show that patients contacting the PHCC for mental health issues often are active agents with their own intent to see a psychologist, not a doctor, as a first-hand choice when contacting the PHCC. Seeking help for mental health issues is described as a sensitive issue that demands building up strength before contacting. The quick access to the preferred health-care professional is appreciated. The nurse was perceived as a caring facilitator rather than a decision maker. It is the patient's wish rather than the symptoms that directs the sorting. The patients' expectations when meeting the psychologist were wide and diverse. The structured assessment sometimes collided and sometimes united with these expectations, yielding different outcome satisfaction. The results could be seen in line with the present goal to increase patients' choice in the health-care system. The improved accessibility to the psychologist seems to meet community expectations. The results also indicate a need for providing more prior information about the assessment and potential outcomes.

Small bowel capsule endoscopy represents a significant advance in the investigation of the small bowel, allowing direct visualization of this section of the gastrointestinal system. More recently, new video capsules have been released, specifically designed to investigate the esophagus and the colon. In June 2006, Given Imaging Ltd received marketing clearance from the US FDA for the Rapid Access Real-Time (RT) and Rapid Access software. The Rapid Access RT is a handheld device that enables real-time viewing during capsule endoscopy procedures. To date, the clinical benefits of this device are unknown as studies on the Rapid Access RT system have not yet been published. However, it appears that the Rapid Access RT system may reduce the examination and reading time, and may impact significantly in cases where it is important to know the precise localization of the capsule (during PillCam ESO ingestion procedures, PillCam Colon examinations or when delayed gastric transit is suspected) or in case of severe gastrointestinal bleeding (when a therapeutic procedure is required urgently).

The patient population staying in nursing homes is increasingly vulnerable and dependent and should benefit from a direct access to an acute care geriatric unit. Nevertheless, the easy access by a simple phone call from the general practitioner to the geriatrician, as well as the lack of orientation of these patients by emergency units, might lead to inappropriate admissions. This work studied the appropriateness of direct admissions of 40 patients living in nursing home in an acute care geriatric unit. Based on the AEPf assessment grid, 82.5% of these admissions were considered as appropriate (52.5%) or justified (30% based on an expert panel decision), and 17.5% were inappropriate. In conclusion, the process of direct admission does not seem to increase the rate of inappropriate admissions. Some actions could decrease this rate: implementation of geriatric mobile teams or psychogeriatric mobile teams intervening in nursing home, a better and more adapted use of ambulatory structures, a better information to the general practitioners. In order to reduce the intervention of the panel of experts, an adaptation of the AEPf assessment grid to these geriatric patients has been proposed. The "AEPg" assessment grid should benefit from a validation study.

HIV vaccines: current challenges and future directions.
Avrett, Sam; Collins, Chris
2002-07-01
Volume seven of the Review will mark the tenth anniversary of the Canadian HIV/AIDS Legal Network with a series of articles that describe past developments and future directions in several areas of policy and law related to HIV/AIDS. The following article is the first of these, discussing current challenges and future directions in the development of and access to HIV vaccines. It argues that governments are under public health, ethical, and legal obligations to develop and provide access to HIV vaccines. It further explains what is required for governments to fulfill their obligations: additional commitment and resources for HIV vaccine development in the context of increased global research and development regarding diseases of the poor; increased support and advocacy for partnerships to develop HIV vaccines; enhanced regulatory capacity in every country to review, approve, and monitor HIV vaccines; and assurance of global supply of, procurement of, delivery of, and access to vaccines in the context of efforts to increase global access to public health measures and technologies.

Poor readers' retrieval mechanism: efficient access is not dependent on reading skill
Johns, Clinton L.; Matsuki, Kazunaga; Van Dyke, Julie A.
2015-01-01
A substantial body of evidence points to a cue-based direct-access retrieval mechanism as a crucial component of skilled adult reading. We report two experiments aimed at examining whether poor readers are able to make use of the same retrieval mechanism. This is significant in light of findings that poor readers have difficulty retrieving linguistic information (e.g., Perfetti, 1985). Our experiments are based on a previous demonstration of direct-access retrieval in language processing, presented in McElree et al. (2003). Experiment 1 replicates the original result using an auditory implementation of the Speed-Accuracy Tradeoff (SAT) method. This finding represents a significant methodological advance, as it opens up the possibility of exploring retrieval speeds in non-reading populations. Experiment 2 provides evidence that poor readers do use a direct-access retrieval mechanism during listening comprehension, despite overall poorer accuracy and slower retrieval speeds relative to skilled readers. The findings are discussed with respect to hypotheses about the source of poor reading comprehension. PMID:26528212

The Myth of Spatial Reuse with Directional Antennas in Indoor Wireless Networks
NASA Astrophysics Data System (ADS)
Lakshmanan, Sriram; Sundaresan, Karthikeyan; Rangarajan, Sampath; Sivakumar, Raghupathy
Interference among co-channel users is a fundamental problem in wireless networks, which prevents nearby links from operating concurrently. Directional antennas allow the radiation patterns of wireless transmitters to be shaped to form directed beams. Conventionally, such beams are assumed to improve the spatial reuse (i.e. concurrency) in indoor wireless networks. In this paper, we use experiments in an indoor office setting of Wifi Access points equipped with directional antennas, to study their potential for interference mitigation and spatial reuse. In contrast to conventional wisdom, we observe that the interference mitigation benefits of directional antennas are minimal. On analyzing our experimental traces we observe that directional links do not reduce interference to nearby links due to the lack of signal confinement due to indoor multipath fading. We then use the insights derived from our study to develop an alternative approach that provides better interference reduction in indoor networks compared to directional links.

Weedy rice infests paddy fields worldwide at an alarmingly increasing rate. There is substantial evidence indicating that many weedy rice forms originated from or are closely related to cultivated rice. There is suspicion that the outbreak of weedy rice in China may be related to widely grown hybrid rice due to its heterosis and the diversity of its progeny, but this notion remains unsupported by direct evidence. We screened weedy rice accessions by both genetic and molecular marker tests for the cytoplasmic male sterility (CMS) genes (Wild abortive, WA, and Boro type, BT) most widely used in the production of indica and japonica three-line hybrid rice as a diagnostic trait of direct parenthood. Sixteen weedy rice accessions of the 358 tested (4.5%) contained the CMS-WA gene; none contained the CMS-BT gene. These 16 accessions represent weedy rices recently evolved from maternal hybrid rice derivatives, given the primarily maternal inheritance of this trait. Our results provide key direct evidence that hybrid rice can be involved in the evolution of some weedy rice accessions, but is not a primary factor in the recent outbreak of weedy rice in China.

Wheelchair accessibility to public buildings in Istanbul.
Evcil, A Nilay
2009-03-01
Accessibility to public environment is the human right and basic need of each citizen and is one of the fundamental considerations for urban planning. The aim of this study is to determine the compliance of public buildings in central business districts (CBD) of Istanbul, Turkey, to wheelchair accessibility to the guidelines of the instrument and identify architectural barriers faced by wheelchair users. This is a descriptive study of 26 public buildings in CBD of Istanbul. The instrument used is the adapted Useh, Moyo and Munyonga questionnaire to collect the data from direct observation and measurement. Descriptive statistics of simple percentages and means are used to explain the compliance to the guidelines of the instrument and wheelchair accessibility. The descriptive survey results indicate that wheelchair users experience many accessibility problems in public environment of the most urbanised city (cultural capital of Europe in 2010) in a developing country. It is found that the major architectural barrier is the public transportation items with the lowest mean compliance (25%). Beside this, the most compliant to the instrument is entrance to building items with 79% as mean percentage. It is also found that there is an intention to improve accessibility when building construction period is investigated. This article describes the example of the compliance of public buildings accessibility when the country has legislation, but lacking regulations about accessibility for the wheelchair users.

This study fills demand for data on access and use of information and communication technologies (ICT) in the Brazilian legal Amazon, a region of localities with identical economic, political, and social problems. We use the 2010 Brazilian Demographic Census to compile data on urban and rural households (i) with computers and Internet access, (ii) with mobile phones, and (iii) with fixed phones. To compare the concentration of access to ICT in the municipalities of the Brazilian Amazon with other regions of Brazil, we use a concentration index to quantify the concentration of households in the following classes: with computers and Internet access, with mobile phones, with fixed phones, and no access. These data are analyzed along with municipal indicators on income, education, electricity, and population size. The results show that for urban households, the average concentration in the municipalities of the Amazon for computers and Internet access and for fixed phones is lower than in other regions of the country; meanwhile, that for no access and mobile phones is higher than in any other region. For rural households, the average concentration in the municipalities of the Amazon for computers and Internet access, mobile phones, and fixed phones is lower than in any other region of the country; meanwhile, that for no access is higher than in any other region. In addition, the study shows that education and income are determinants of inequality in accessing ICT in Brazilian municipalities and that the existence of electricity in rural households is directly associated with the ownership of ICT resources.

Workers' health surveillance: implementation of the Directive 89/391/EEC in Europe.
Colosio, C; Mandic-Rajcevic, S; Godderis, L; van der Laan, G; Hulshof, C; van Dijk, F
2017-10-01
European Union (EU) Directive 89/391 addressed occupational health surveillance, which recommends to provide workers with 'access to health surveillance at regular intervals', aiming to prevent work-related and occupational diseases. To investigate how EU countries adopted this Directive. We invited one selected representative per member state to complete a questionnaire. All 28 EU countries implemented the Directive in some form. Workers' health surveillance (WHS) is available to all workers in 15 countries, while in 12, only specific subgroups have access. In 21 countries, workers' participation is mandatory, and in 22, the employer covers the cost. In 13 countries, access to WHS is not available to all workers but depends on exposure to specific risk factors, size of the enterprise or belonging to vulnerable groups. In 26 countries, the employer appoints and revokes the physician in charge of WHS. Twelve countries have no recent figures, reports or cost-benefit analyses of their WHS programmes. In 15 countries where reports exist, they are often in the native language. Coverage and quality of occupational health surveillance should be evaluated to facilitate learning from good practice and from scientific studies. We propose a serious debate in the EU with the aim of protecting workers more effectively, including the use of evidence-based WHS programmes. © The Author 2017.

Extended cocaine-seeking produces a shift from goal-directed to habitual responding in rats.
Leong, Kah-Chung; Berini, Carole R; Ghee, Shannon M; Reichel, Carmela M
2016-10-01
Cocaine addiction is often characterized by a rigid pattern of behavior in which cocaine users continue seeking and taking drug despite negative consequences associated with its use. As such, full acquisition and relapse of drug-seeking behavior may be attributed to a shift away from goal-directed responding and a shift towards the maladaptive formation of rigid and habit-like responses. This rigid nature of habitual responding can be developed with extended training and is typically characterized by insensitivity to changes in outcome value. The present study determined whether cocaine (primary reinforcer) and cocaine associated cues (secondary reinforcer) could be devalued in rats with different histories of cocaine self-administration. Specifically, rats were trained on two schedules of cocaine self-administration (long-access vs. short-access). Following training the cocaine reinforcer was devalued through three separate pairings of lithium chloride with cocaine infusions. Cocaine history did not have an impact on devaluation of cocaine-associated cues. However, the reinforcing properties of cocaine were devalued only in rats on a short-access cocaine schedule but not those trained on a long-access schedule. Taken together this pattern of findings suggests that, in short access rats, devaluation is specific to the primary reinforcer and not associative stimuli such as cues. Importantly, rats that received extended training during self-administration displayed insensitivity to outcome devaluation of the primary reinforcer as well as all associative stimuli, thus displaying rigid behavioral responding similar to behavioral patterns found in addiction. Alternatively, long access cocaine exposure may have altered the devaluation threshold. Copyright © 2016 Elsevier Inc. All rights reserved.

Envisioning the times of future events: The role of personal goals.
Ben Malek, Hédi; Berna, Fabrice; D'Argembeau, Arnaud
2018-05-25
Episodic future thinking refers to the human capacity to imagine or simulate events that might occur in one's personal future. Previous studies have shown that personal goals guide the construction and organization of episodic future thoughts, and here we sought to investigate the role of personal goals in the process of locating imagined events in time. Using a think-aloud protocol, we found that dates were directly accessed more frequently for goal-related than goal-unrelated future events, and the goal-relevance of events was a significant predictor of direct access to temporal information on a trial-by-trial basis. Furthermore, when an event was not directly dated, references to anticipated lifetime periods were more frequently used as a strategy to determine when a goal-related event might occur. Together, these findings shed new light on the mechanisms by which personal goals contribute to the location of imagined events in future times. Copyright © 2018 Elsevier Inc. All rights reserved.

The U.S. Geological Survey collected hydrologic data between June 2004 and December 2005 to investigate the temporal and spatial nature of flow exchanges through culverts beneath State Road 9336 within Everglades National Park. Continuous data collected during the study measured flow velocity, water level, salinity, conductivity, and water-temperature in or near seven culverts between Pa-hay-okee Overlook access road and Nine Mile Pond. The two culverts east of Pa-hay-okee Overlook access road flowed into Taylor Slough Basin from 87 to 96 percent of the study period, whereas flows through five culverts between Pa-hay-okee Overlook access road and Nine Mile Pond flowed into Shark River Slough Basin from 70 to 99 percent of the study period. Synoptic flow discharges measured at all culverts during three intensive field efforts revealed a net discharge into Taylor Slough Basin from Shark River Slough Basin through culverts between Royal Palm Road and Pa-hay-okee Overlook access road, and into Shark River Slough Basin from Taylor Slough Basin through culverts between Pa-hay-okee Overlook access road and Nine Mile Pond. Data collected during the study and presented in this report provided additional knowledge of the magnitude, direction, and nature of flow exchanges through the road culverts.

Reflecting the commitments undertaken by the EU through the conclusion of the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD), the European Disability Strategy 2010–2020 not only gives a prominent position to accessibility, broadly interpreted, but also suggests an examination of the obligations for access to cultural goods and services. The European Disability Strategy 2010–2020 expressly acknowledges that EU action will support national activities to make sports, leisure, cultural and recreational organizations and activities accessible, and use the possibilities for copyright exceptions in the Directive 2001/29/EC (Infosoc Directive). This article discusses to what extent the EU has realized the principle of accessibility and the right to access cultural goods and services envisaged in the UNCRPD. Previous research has yet to explore how web accessibility and digitization interact with the cultural dimension of disability policy in the European Union. This examination attempts to fill this gap by discussing to what extent the European Union has put this cultural dimension into effect and how web accessibility policies and the digitization of cultural materials influence these efforts.

Implantable medical devices (IMDs) have played an important role in many medical fields. Any failure in IMDs operations could cause serious consequences and it is important to protect the IMDs access from unauthenticated access. This study investigates secure IMD data collection within a telehealthcare [mobile health (m-health)] network. We use medical sensors carried by patients to securely access IMD data and perform secure sensor-to-sensor communications between patients to relay the IMD data to a remote doctor's server. To meet the requirements on low computational complexity, we choose N-th degree truncated polynomial ring (NTRU)-based encryption/decryption to secure IMD-sensor and sensor-sensor communications. An extended matryoshkas model is developed to estimate direct/indirect trust relationship among sensors. An NTRU hardware implementation in very large integrated circuit hardware description language is studied based on industry Standard IEEE 1363 to increase the speed of key generation. The performance analysis results demonstrate the security robustness of the proposed IMD data access trust model.

Cloud computing has been increasingly adopted by users and providers to promote a flexible, scalable and tailored access to computing resources. Nonetheless, the consolidation of this paradigm has uncovered some of its limitations. Initially devised by corporations with direct control over large amounts of computational resources, cloud computing is now being endorsed by organizations with limited resources or with a more articulated, less direct control over these resources. The challenge for these organizations is to leverage the benefits of cloud computing while dealing with limited and often widely distributed computing resources. This study focuses on the adoption of cloud computing by higher education institutions and addresses two main issues: flexible and on-demand access to a large amount of storage resources, and scalability across a heterogeneous set of cloud infrastructures. The proposed solutions leverage a federated approach to cloud resources in which users access multiple and largely independent cloud infrastructures through a highly customizable broker layer. This approach allows for a uniform authentication and authorization infrastructure, a fine-grained policy specification and the aggregation of accounting and monitoring. Within a loosely coupled federation of cloud infrastructures, users can access vast amount of data without copying them across cloud infrastructures and can scale their resource provisions when the local cloud resources become insufficient.

The special role of item-context associations in the direct-access region of working memory.
Campoy, Guillermo
2017-09-01
The three-embedded-component model of working memory (WM) distinguishes three representational states corresponding to three WM regions: activated long-term memory, direct-access region (DAR), and focus of attention. Recent neuroimaging research has revealed that access to the DAR is associated with enhanced hippocampal activity. Because the hippocampus mediates the encoding and retrieval of item-context associations, it has been suggested that this hippocampal activation is a consequence of the fact that item-context associations are particularly strong and accessible in the DAR. This study provides behavioral evidence for this view using an item-recognition task to assess the effect of non-intentional encoding and maintenance of item-location associations across WM regions. Five pictures of human faces were sequentially presented in different screen locations followed by a recognition probe. Visual cues immediately preceding the probe indicated the location thereof. When probe stimuli appeared in the same location that they had been presented within the memory set, the presentation of the cue was expected to elicit the activation of the corresponding WM representation through the just-established item-location association, resulting in faster recognition. Results showed this same-location effect, but only for items that, according to their serial position within the memory set, were held in the DAR.

Objective: Direct access to physiotherapy services is currently discussed in Germany. Its introduction would mean that initial diagnoses must be made in physiotherapy practices as well. However, it was not yet investigated whether the current training in physiotherapy is sufficient for this, and whether there are differences between the training systems. This study aims to answer the question of whether trainees at the end of Bachelor's studies (BS) are more reliably able to assess the case-related suitability of examination methods than professional college students (FS). Methodology: Questionnaires were developed to assess the suitability of examination methods for diagnostic inquiries. All professional colleges and bachelor's study courses listed with the German Physiotherapy Association were asked to present the questionnaires to their final classes. Results: In 216 addressed professional colleges and 24 bachelor's study courses, the return rate was 9.26% for professional colleges and 33.33% for study courses. One hundred thirty-eight questionnaires from students in 8 study courses and 368 questionnaires from students at 20 professional colleges were evaluated. The mean of correct decisions in total (of max. 54) was 19.01 (BS) or 15.73 (FS); in structure-related and function-related examination methods (of max. 42), it was 17.22 (BS) and 14.8 (FS); in activity-related methods (of max. 12), it was 1.97 (BS) and 0.89 (FS). Out of a max. of 49 examination methods, 23.45 (BS) and 26.72 (FS) were stated as unknown. Conclusion: The university students made correct decisions on the suitability of examination methods significantly more frequently than the professional college students. However, the determined group difference is low. Overall, the results do not appear sufficient for direct access. Training would have to be adapted for this purpose.

The Internet is a common source of information for orthopaedic residents applying for sports medicine fellowships, with the web sites of the American Orthopaedic Society for Sports Medicine (AOSSM) and the San Francisco Match serving as central databases. We sought to evaluate the web sites for accredited orthopaedic sports medicine fellowships with regard to content and accessibility. We reviewed the existing web sites of the ninety-five accredited orthopaedic sports medicine fellowships included in the AOSSM and San Francisco Match databases from February to March 2012. A Google search was performed to determine the overall accessibility of program web sites and to supplement information obtained from the AOSSM and San Francisco Match web sites. The study sample consisted of the eighty-seven programs whose web sites connected to information about the fellowship. Each web site was evaluated for its informational value. Of the ninety-five programs, fifty-one (54%) had links listed in the AOSSM database. Three (3%) of all accredited programs had web sites that were linked directly to information about the fellowship. Eighty-eight (93%) had links listed in the San Francisco Match database; however, only five (5%) had links that connected directly to information about the fellowship. Of the eighty-seven programs analyzed in our study, all eighty-seven web sites (100%) provided a description of the program and seventy-six web sites (87%) included information about the application process. Twenty-one web sites (24%) included a list of current fellows. Fifty-six web sites (64%) described the didactic instruction, seventy (80%) described team coverage responsibilities, forty-seven (54%) included a description of cases routinely performed by fellows, forty-one (47%) described the role of the fellow in seeing patients in the office, eleven (13%) included call responsibilities, and seventeen (20%) described a rotation schedule. Two Google searches identified direct links for 67% to 71% of all accredited programs. Most accredited orthopaedic sports medicine fellowships lack easily accessible or complete web sites in the AOSSM or San Francisco Match databases. Improvement in the accessibility and quality of information on orthopaedic sports medicine fellowship web sites would facilitate the ability of applicants to obtain useful information.

Heard it through the grapevine: indirect networks and employee creativity.
Hirst, Giles; Van Knippenberg, Daan; Zhou, Jing; Quintane, Eric; Zhu, Cherrie
2015-03-01
Social networks can be important sources of information and insights that may spark employee creativity. The cross-fertilization of ideas depends not just on access to information and insights through one's direct network-the people one actually interacts with--but at least as much on access to the indirect network one's direct ties connect one to (i.e., people one does not interact with directly, but with whom one's direct ties interact). We propose that the reach efficiency of this indirect network--its nonredundancy in terms of interconnections--is positively related to individual creativity. To help specify the boundaries of this positive influence of the indirect network, we also explore how many steps removed the indirect network still adds to creativity. In addition, we propose that the efficiency (nonredundancy) of one's direct network is important here, because more efficient direct networks give one access to indirect networks with greater reach efficiency. Our hypotheses were supported in a multilevel analysis of multisource survey data from 223 sales representatives nested within 11 divisions of a Chinese pharmaceutical company. This analysis also showed that the creative benefits of reach efficiency were evident for 3 and 4 degrees of separation but were greatest for indirect ties that depend only on one's direct ties.

Cost is frequently reported as a barrier to cataract surgery, but few studies have reported costs of accessing surgery in Africa. The purpose of this prospective, facility based study was to compare direct non-medical cost with total direct cost of cataract surgery to patients, and to assess how money was found to cover costs. Participants were those aged 17 years and above attending their first post-operative visit after first eye, subsidised, day case cataract surgery. Systematic random sampling was used to select participants who were interviewed to obtain data on socio-demographic details, and on expenditure during the assessment visit, the surgical visit, and the first follow-up visit. Costs were a) direct medical costs (patients' costs for registration, investigations, surgery, medication), and b) direct non-medical costs (patients' and escorts' costs for transport, accommodation, meals). The source of funds to pay for the services received was also assessed. Almost two thirds (63%) of the 104 participants were men. The mean age of men was 64 (± 12.5) years, being 63 (± 12.9) years for women. All men were married and 35% of women were widows. 84% of men were household heads compared with 6% of women. The median total direct cost for all visits by all participants was N8,245 (US$51), being higher for men than women (N9,020; US$56 and N7,620; US$47) (p < 0.09) respectively. Direct non-medical cost constituted 49% of total direct cost. 92% of participants had adequate money to pay, but 8% had to sell possessions to raise the money. 20% of unmarried women sold possessions or took out a loan. Despite the subsidy, cost is still likely to be a barrier to accessing cataract surgery, as the total direct costs represented at least 50 days income for 70% of the local population. Provision of transport would reduce direct non-medical costs.

Abstract Background: Delivering specialty care remotely directly into people's homes can enhance access for and improve the healthcare of individuals with chronic conditions. However, evidence supporting this approach is limited. Materials and Methods: Connect.Parkinson is a randomized comparative effectiveness study that compares usual care of individuals with Parkinson's disease in the community with usual care augmented by virtual house calls with a Parkinson's disease specialist from 1 of 18 centers nationally. Individuals in the intervention arm receive four virtual visits from a Parkinson's disease specialist over 1 year via secure, Web-based videoconferencing directly into their homes. All study activities, including recruitment, enrollment, and assessments, are conducted remotely. Here we report on interest, feasibility, and barriers to enrollment in this ongoing study. Results: During recruitment, 11,734 individuals visited the study's Web site, and 927 unique individuals submitted electronic interest forms. Two hundred ten individuals from 18 states enrolled in the study from March 2014 to June 2015, and 195 were randomized. Most participants were white (96%) and college educated (73%). Of the randomized participants, 73% had seen a Parkinson's disease specialist within the previous year. Conclusions: Among individuals with Parkinson's disease, national interest in receiving remote specialty care directly into the home is high. Remote enrollment in this care model is feasible but is likely affected by differential access to the Internet. PMID:26886406

To evaluate the stress distribution of the cervical-defected incisor with labial or lingual endodontic access with finite element analysis (FEA), and to explore the advantage of resistance in labial endodontic access. 3-D finite element models of upper cervical-defected incisor were established using cone-beam CT (CBCT), Mimics Catia, and Ansys software. The subjects were categorized according to the two endodontic accesses and three restorative ways, which were composite resin, glass fiber-reinforced composite resin and glass fiber-reinforced post-crown. All the models were loaded.The von Mises stress values and distribution were recorded and analyzed with Ansys 10.0 software. In this study, direct composite resin restoration showed no significant difference between the labial and lingual access. In glass fiber-reinforced composite resin, labial access could transfer the stress concentration area. It could reduce the incidence of fracture of the cervical lesion but increase the incidence of root fracture. Post-crown restoration could obviously reduce the incidence of fracture of the cervical lesion. When the cervical-defected incisor is restored with composite resin, labial and lingual accesses can be considered. Labial access with glass fiber-reinforced composite resin or post-crown restoration is a good choice.

What systems participants know about access and service entry and why managers should listen.
Duncombe, Rohena
2017-08-01
Objective The present study looked at the views of people directly involved in the entry process for community health counselling using the frame of the health access literature. The concurrence of system participants' views with the access literature highlights access issues, particularly for people who are vulnerable or disadvantaged. The paper privileges the voices of the system participants, inviting local health services to consider using participatory design to improve access at the entry point. Methods People involved in the entry process for community health counselling explored the question, 'What, for you, are the features of a good intake system?' They also commented on themes identified during pilot interviews. These were thematically analysed for each participant group by the researcher to develop a voice for each stakeholder group. Results People accessing the service could be vulnerable and the entry process failed to take that into account. People directly involved in the counselling service entry system, system participants, consisted of: professionals referring in, people seeking services and reception staff taking first enquiries. They shared substantially the same concerns as each other. The responses from these system participants are consistent with the international literature on access and entry into health services. Conclusion Participatory service design could improve primary healthcare service entry at the local level. Canvassing the experiences of system participants is important for delivering services to those who have the least access and, in that way, could contribute to health equity. What is known about the topic? People with the highest health needs receive the fewest services. Health inequality is increasing. What does this paper add? System participants can provide advice consistent with the academic research literature that is useful for improving service entry at the local level. What are the implications for practitioners? Participatory design can inform policy makers and service providers. Entry systems could acknowledge the potential vulnerability or disadvantage of people approaching the service.

It has recently been proposed that electronic band structures in crystals can give rise to a previously overlooked type of Weyl fermion, which violates Lorentz invariance and, consequently, is forbidden in particle physics. It was further predicted that Mo x W 1 - x Te 2 may realize such a type-II Weyl fermion. Here, we first show theoretically that it is crucial to access the band structure above the Fermi level ε F to show a Weyl semimetal in Mo x W 1 - x Te 2 . Then, we study Mo x W 1 - x Te 2 bymore » pump-probe ARPES and we directly access the band structure > 0.2 eV above ε F in experiment. By comparing our results with ab initio calculations, we conclude that we directly observe the surface state containing the topological Fermi arc. We propose that a future study of Mo x W 1 - x Te 2 by pump-probe ARPES may directly pinpoint the Fermi arc. Our work sets the stage for the experimental discovery of the first type-II Weyl semimetal in Mo x W 1 - x Te 2 .« less

Lateral-access Class II restoration using resin-modified glass-ionomer or silver-cermet cement.
Croll, T P
1995-02-01
Direct-access preparation of a carious proximal surface is perhaps the most conservative approach to restoration. Physical properties and handling characteristics of silver amalgam and of resin composite and lack of fluoride ion release make these materials unsuitable for direct buccal- or lingual-access proximal restoration. Insufficient strengths and radiolucency of self-hardening glass-ionomer cements preclude their use for Class II restorations. However, glass-ionomer silver-cermet cement and some resin-modified glass-ionomer materials are proving useful for non-stress-bearing Class II restorations and may have applications in preventive dentistry. This article describes lateral-access Class II restoration with modified glass-ionomer cements. Emphasis is placed on careful handling of materials, maintenance of an ideal operative field, and conservation of tooth structure.

Adolescents Searching for Health Information on the Internet: An Observational Study
Derry, Holly A; Resnick, Paul J; Richardson, Caroline R
2003-01-01
Background Adolescents' access to health information on the Internet is partly a function of their ability to search for and find answers to their health-related questions. Adolescents may have unique health and computer literacy needs. Although many surveys, interviews, and focus groups have been utilized to understand the information-seeking and information-retrieval behavior of adolescents looking for health information online, we were unable to locate observations of individual adolescents that have been conducted in this context. Objective This study was designed to understand how adolescents search for health information using the Internet and what implications this may have on access to health information. Methods A convenience sample of 12 students (age 12-17 years) from 1 middle school and 2 high schools in southeast Michigan were provided with 6 health-related questions and asked to look for answers using the Internet. Researchers recorded 68 specific searches using software that captured screen images as well as synchronized audio recordings. Recordings were reviewed later and specific search techniques and strategies were coded. A qualitative review of the verbal communication was also performed. Results Out of 68 observed searches, 47 (69%) were successful in that the adolescent found a correct and useful answer to the health question. The majority of sites that students attempted to access were retrieved directly from search engine results (77%) or a search engine's recommended links (10%); only a small percentage were directly accessed (5%) or linked from another site (7%). The majority (83%) of followed links from search engine results came from the first 9 results. Incorrect spelling (30 of 132 search terms), number of pages visited within a site (ranging from 1-15), and overall search strategy (eg, using a search engine versus directly accessing a site), were each important determinants of success. Qualitative analysis revealed that participants used a trial-and-error approach to formulate search strings, scanned pages randomly instead of systematically, and did not consider the source of the content when searching for health information. Conclusions This study provides a useful snapshot of current adolescent searching patterns. The results have implications for constructing realistic simulations of adolescent search behavior, improving distribution and usefulness of Web sites with health information relevant to adolescents, and enhancing educators' knowledge of what specific pitfalls students are likely to encounter.

Spatial memory facilitates resource acquisition where resources are patchy, but how it influences movement behaviour of wide-ranging species remains to be resolved. We examined African elephant spatial memory reflected in movement decisions regarding access to perennial waterholes. State–space models of movement data revealed a rapid, highly directional movement behaviour almost exclusively associated with visiting perennial water. Behavioural change point (BCP) analyses demonstrated that these goal-oriented movements were initiated on average 4.59 km, and up to 49.97 km, from the visited waterhole, with the closest waterhole accessed 90% of the time. Distances of decision points increased when switching to different waterholes, during the dry season, or for female groups relative to males, while selection of the closest waterhole decreased when switching. Overall, our analyses indicated detailed spatial knowledge over large scales, enabling elephants to minimize travel distance through highly directional movement when accessing water. We discuss the likely cognitive and socioecological mechanisms driving these spatially precise movements that are most consistent with our findings. By applying modern analytic techniques to high-resolution movement data, this study illustrates emerging approaches for studying how cognition structures animal movement behaviour in different ecological and social contexts.

The purpose of this researcher was to examine specific environmental, educational, and demographic factors and their influence on mathematics and science achievement. In particular, the researcher ascertained the interconnections of home computer access and social capital, with Asian American students and the effect on mathematics and science achievement. Coleman's theory on social capital and parental influence was used as a basis for the analysis of data. Subjects for this study were the base year students from the National Education Longitudinal Study of 1988 (NELS:88) and the subsequent follow-up survey data in 1990, 1992, and 1994. The approximate sample size for this study is 640 ethnic Asians from the NELS:88 database. The analysis was a longitudinal study based on the Student and Parent Base Year responses and the Second Follow-up survey of 1992, when the subjects were in 12th grade. Achievement test results from the NELS:88 data were used to measure achievement in mathematics and science. The NELS:88 test battery was developed to measure both individual status and a student's growth in a number of achievement areas. The subject's responses were analyzed by principal components factor analysis, weights, effect sizes, hierarchial regression analysis, and PLSPath Analysis. The results of this study were that prior ability in mathematics and science is a major influence in the student's educational achievement. Findings from the study support the view that home computer access has a negative direct effect on mathematics and science achievement for both Asian American males and females. None of the social capital factors in the study had either a negative or positive direct effect on mathematics and science achievement although some indirect effects were found. Suggestions were made toward increasing parental involvement in their children's academic endeavors. Computer access in the home should be considered related to television viewing and should be closely monitored by the parents to promote educational uses.

As physicians seek innovative practice models, one that is gaining ground is for practices to contract with patients to pay directly for some or all services-often called cash-only, retainer, boutique, concierge, or direct primary care or specialty care practices. Such descriptions do not reflect the variability found in practices. For the purposes of this paper, the American College of Physicians (ACP) defines a direct patient contracting practice (DPCP) as any practice that directly contracts with patients to pay out-of-pocket for some or all of the services provided by the practice, in lieu of or in addition to traditional insurance arrangements, and/or charges an administrative fee to patients, sometimes called a retainer or concierge fee, often in return for a promise of more personalized and accessible care. This definition encompasses the practice types previously described. The move to DPCPs is based on the premise that access and quality of care will be improved without third-party payers imposing themselves between the patient and the physician. Yet concerns have been raised that DPCPs may cause access issues for patients who cannot afford to pay directly for care. This ACP position paper, initiated and written by its Medical Practice and Quality Committee and approved by the Board of Regents on 25 July 2015, assesses the impact of DPCPs on access, cost, and quality; discusses principles from the ACP Ethics Manual, Sixth Edition, that should apply to all practice types; and makes recommendations to mitigate any adverse effect on underserved patients.

An International Survey of Veterinary Students to Assess Their Use of Online Learning Resources.
Gledhill, Laura; Dale, Vicki H M; Powney, Sonya; Gaitskell-Phillips, Gemma H L; Short, Nick R M
Today's veterinary students have access to a wide range of online resources that support self-directed learning. To develop a benchmark of current global student practice in e-learning, this study measured self-reported access to, and use of, these resources by students internationally. An online survey was designed and promoted via veterinary student mailing lists and international organizations, resulting in 1,070 responses. Analysis of survey data indicated that students now use online resources in a wide range of ways to support their learning. Students reported that access to online veterinary learning resources was now integral to their studies. Almost all students reported using open educational resources (OERs). Ownership of smartphones was widespread, and the majority of respondents agreed that the use of mobile devices, or m-learning, was essential. Social media were highlighted as important for collaborating with peers and sharing knowledge. Constraints to e-learning principally related to poor or absent Internet access and limited institutional provision of computer facilities. There was significant geographical variation, with students from less developed countries disadvantaged by limited access to technology and networks. In conclusion, the survey provides an international benchmark on the range and diversity in terms of access to, and use of, online learning resources by veterinary students globally. It also highlights the inequalities of access among students in different parts of the world.

2011-01-01
Individuals working in the sex industry continue to experience many negative health outcomes. As such, disentangling the factors shaping poor health access remains a critical public health priority. Within a quasi-criminalised prostitution environment, this study aimed to evaluate the prevalence of occupational stigma associated with sex work and its relationship to barriers to accessing health services. Analyses draw on baseline questionnaire data from a community-based cohort of women in street-based sex work in Vancouver, Canada (2006–8). Of a total of 252 women, 141 (58.5%) reported occupational sex work stigma (defined as hiding occupational sex work status from family, friends and/or home community), while 125 (49.6%) reported barriers to accessing health services in the previous six months. In multivariable analysis, adjusting for socio-demographic, interpersonal and work environment risks, occupational sex work stigma remained independently associated with an elevated likelihood of experiencing barriers to health access. Study findings indicate the critical need for policy and societal shifts in views of sex work as a legitimate occupation, combined with improved access to innovative, accessible and non-judgmental health care delivery models for street-based sex workers that include the direct involvement of sex workers in development and implementation.

In passive optical network (PON), orthogonal frequency division multiplexing (OFDM) has been studied actively due to its advantages such as high spectra efficiency (SE), dynamic resource allocation in time or frequency domain, and dispersion robustness. However, orthogonal frequency division multiple access (OFDMA)-PON requires tight synchronization among multiple access signals. If not, frequency orthogonality could not be maintained. Also its sidelobe causes inter-channel interference (ICI) to adjacent channel. To prevent ICI caused by high sidelobes, guard band (GB) is usually used which degrades SE. Thus, OFDMA-PON is not suitable for asynchronous uplink transmission in optical access network. In this paper, we propose intensity modulation/direct detection (IM/DD) based universal filtered multi-carrier (UFMC) PON for asynchronous multiple access. The UFMC uses subband filtering to subsets of subcarriers. Since it reduces sidelobe of each subband by applying subband filtering, it could achieve better performance compared to OFDM. For the experimental demonstration, different sample delay was applied to subbands to implement asynchronous transmission condition. As a result, time synchronization robustness of UFMC was verified in asynchronous multiple access system.

Access to the French drug market is being impacted by an ongoing dramatic shift in practice as well as by two laws that came into force in December 2011. This new environment has been described and analyzed in two separate articles. This second article analyzes how this new environment will actually impact the access to French drug market. French drug market access will be increasingly driven by comparative-effectiveness and cost-effectiveness data, and an increased role of postmarketing studies in the years to come. This access is evolving in a more complex environment for stakeholders due to the uncertainties surrounding these changes and it will be more complex and difficult for the pharmaceutical industry to address. The main issue faced by the pharmaceutical companies will be to minimize uncertainty at the time of a drug's launch to narrow the decision window. This is a major change of paradigm for the pharmaceutical business, in which pre- and postlaunch risks are directed toward the pharmaceutical industry. PMID:27226829

Accessible Home Environments for People with Functional Limitations: A Systematic Review.
Cho, Hea Young; MacLachlan, Malcolm; Clarke, Michael; Mannan, Hasheem
2016-08-17
The aim of this review is to evaluate the health and social effects of accessible home environments for people with functional limitations, in order to provide evidence to promote well-informed decision making for policy guideline development and choices about public health interventions. MEDLINE and nine other electronic databases were searched between December 2014 and January 2015, for articles published since 2004. All study types were included in this review. Two reviewers independently screened 12,544 record titles or titles and abstracts based on our pre-defined eligibility criteria. We identified 94 articles as potentially eligible; and assessed their full text. Included studies were critically appraised using the Mixed Method Appraisal Tool, version 2011. Fourteen studies were included in the review. We did not identify any meta-analysis or systematic review directly relevant to the question for this systematic review. A narrative approach was used to synthesise the findings of the included studies due to methodological and statistical heterogeneity. Results suggest that certain interventions to enhance the accessibility of homes can have positive health and social effects. Home environments that lack accessibility modifications appropriate to the needs of their users are likely to result in people with physical impairments becoming disabled at home.

Latin America (LA) has a unique structural, political, cultural and social environment. This study aimed to identify the places where Latin American adults are physically active; and to determine the association of using public- and restricted-access places with physical activity (PA). We used data from the International PA Environment Network study in Bogota, Colombia (n=1000, accelerometry=249); Cuernavaca, Mexico (n=677, accelerometry=652); and Curitiba, Brazil (n=697, accelerometry=331) (2010-2011). Walking and moderate-to-vigorous PA for leisure were measured with the International Physical Activity Questionnaire. Overall PA and PA within 10-minute bouts were measured with accelerometers. Participants reported use of public- and restricted-access places for PA. Mixed-effects regression models were used to determine the association of using public- and restricted-access places with PA. The streets were the most frequently-reported place for PA, and walking was the most common PA in the studied places. 'Informal', non-exercise-or-sports places (e.g., shopping malls) ranked high for use for PA in Bogota and Cuernavaca. In Curitiba, use of 'formal' places for sports/exercise (e.g., gyms) was more prevalent. Using public-access places was directly related to walking for leisure in all cities, and to additional PA outcomes in Bogota and Cuernavaca. In Cuernavaca and Curitiba, using restricted-access places was also associated with PA. Our study highlights the importance of public-access places for PA in LA. In some contexts, places for social interaction may be as important for PA as places for exercise/sport. Strategies increasing the availability, accessibility and quality of these places may effectively promote PA in LA. Copyright © 2016 Elsevier Inc. All rights reserved.

Supporting drivers in forming correct expectations about transitions between rural road categories.
Stelling-Konczak, Agnieszka; Aarts, Letty; Duivenvoorden, Kirsten; Goldenbeld, Charles

In order to support drivers in forming the right expectations on the road, road categories are being made recognisable and predictable in the Netherlands. The present study investigated which of the selected road layouts can make rural road categories most recognisable for road users, especially in transitions from one road category to another. A second objective was to study whether explicit information could contribute to a better recognisability of transitions. The experiment was performed with a series of photographs showing sections of two road categories with an intersection in between. The road layout of road categories varied in markings and separation of driving direction (within-subjects factor). Informed and non-informed participants (between-subjects factor) had to indicate their expectations regarding speed limit and access restriction of each road section, before and after a transition. The results show that for transitions between distributor and through roads, the physicality of separation of driving direction is a better distinctive characteristic than the currently used edge marking. The green centre marking on through roads also enhances recognisability, but only with additional information. As far as transitions between distributor and access roads are concerned, the results demonstrate that this type of transitions is better recognised when no markings on access roads are present. Physical separation of driving directions on distributor roads also improves recognisability, although this layout is associated with higher speed limits. Providing explicit information has in general a positive effect on the reconisability of transitions. Implications are discussed in the light of potential safety effects.

A national study of the association between food environments and county-level health outcomes.
Ahern, Melissa; Brown, Cheryl; Dukas, Stephen
2011-01-01
This national, county-level study examines the relationship between food availability and access, and health outcomes (mortality, diabetes, and obesity rates) in both metro and non-metro areas. This is a secondary, cross-sectional analysis using Food Environment Atlas and CDC data. Linear regression models estimate relationships between food availability and access variables (direct-to-consumer farm sales, per capita grocery stores, full-service restaurants, fast food restaurants, and convenience stores) with health outcomes. Controls include smoking, race/ethnicity, gender, age, education, poverty, primary care availability, recreational facility availability, and mobility/distance-from-grocery-store. Non-metro findings: Lower adjusted mortality rates were associated with more per capita full-service restaurants and grocery stores, and greater per capita direct farm sales. Lower adjusted diabetes rates were associated with a lower per capita supply of fast food restaurants and convenience stores, and more per capita full-service restaurants and grocery stores. Lower adjusted obesity rates were associated with more per capita full-service restaurants and grocery stores. Unexpectedly, obesity rates were positively associated with per capita grocery stores and negatively associated with fast food restaurants. Metro findings: More per capita full-service restaurants, grocery stores, and direct farm sales are associated with positive health outcomes; fast food restaurants and convenience stores are associated with negative health outcomes. The food access/availability environment is an important determinant of health outcomes in metro and non-metro areas. Future research should focus on more refined specifications that capture variability across non-metro settings. © 2011 National Rural Health Association.

2018-01-15
Re-emergence of ZIKV has caused infections in more than 1.5 million people. The molecular mechanism and pathogenesis of ZIKV is not well explored due to unavailability of adequate model and lack of publically accessible resources to provide information of ZIKV-Human protein interactome map till today. This study made an attempt to curate the ZIKV-Human interaction proteins from published literatures and RNA-Seq data. 11 direct interaction, 12 associated genes are retrieved from literatures and 3742 Differentially Expressed Genes (DEGs) are obtained from RNA-Seq analysis. The genes have been analyzed to construct the ZIKV-Human Interactome Map. The importance of the study has been illustrated by the enrichment analysis and observed that direct interaction and associated genes are enriched in viral entry into host cell. Also, ZIKV infection modulates 32% signal and 27% immune system pathways. The integrated database, ZikaBase has been developed to help the virology research community and accessible at https://test5.bicpu.edu.in. Copyright © 2017 Elsevier Inc. All rights reserved.

Using a variety of tools is a common and essential component of modern human life. Patients with brain damage or neurological disorders frequently have cognitive deficits in their recognition and manipulation of tools. In this study, we focused on improving tool-related cognition using transcranial direct current stimulation (tDCS). Converging evidence from neuropsychology, neuroimaging and non- invasive brain stimulation has identified the anterior temporal lobe (ATL) and inferior parietal lobule (IPL) as brain regions supporting action semantics. We observed enhanced performance in tool cognition with anodal tDCS over ATL and IPL in two cognitive tasks that require rapid access to semantic knowledge about the function or manipulation of common tools. ATL stimulation improved access to both function and manipulation knowledge of tools. The effect of IPL stimulation showed a trend toward better manipulation judgments. Our findings support previous studies of tool semantics and provide a novel approach for manipulation of underlying circuits.

The use of totally implantable venous access devices developed as a medical device allowing mid- and long-term, frequent, repeated, or continuous injection of therapeutic products, by vascular, cavitary, or perineural access. The effective flushing of these devices is a central element to assure long-lasting use. Our experimental work demonstrates that directing the Huber point needle opening in the diametrically opposite direction of the implantable port exit channel increases the flushing efficiency. These results are consolidated by numerical computations, which support recommendations not only for their maintenance, but also for their use.

Endovascular embolization has become increasingly favored over microsurgical resection for treatment of complex dural arteriovenous fistulas (DAVFs). However, endovascular treatment can be restricted by tortuous transarterial access and a transvenous approach is not always feasible. We present a Borden III DAVF treated by direct access to the middle meningeal artery (MMA) and Onyx embolization performed in a hybrid operating room–angiography suite. A middle-aged patient with pulsatile headaches was found to have left transverse sinus occlusion and DAVF with retrograde cortical venous drainage fed by multiple external carotid artery (ECA) feeders. Endovascular attempts via conventional transvenous and transarterial routes were unsuccessful, and the major MMA feeder was accessed directly after temporal craniotomy was performed under neuronavigation. Onyx embolization was performed; complete occlusion of the fistula was achieved. Three-month follow-up angiography showed no residual filling; the patient remains complication-free. A combined surgical–endovascular technique in a hybrid operating room–angiography suite can be an effective treatment for DAVFs complicated by inaccessible arterial and transvenous approaches.

Anxiety disorders are among the most common mental health disorders experienced by children, but only a minority of these children access professional help. Understanding the difficulties parents face seeking support for child anxiety disorders could inform targeted interventions to improve treatment access. The aims of the study were to identify barriers and facilitators to seeking and accessing professional support for child anxiety disorders, and ways to minimise these barriers. A qualitative interview study was conducted with parents of 16 children (aged 7-11 years) with anxiety disorders identified through screening in schools. Barriers and facilitators were identified in relation to four distinct stages in the help-seeking process: parents recognising the anxiety difficulty, parents recognising the need for professional support, parents contacting professionals, and families receiving professional support. Barriers and facilitators at each stage related to the child's difficulties, the role of the parent, and parent perceptions of professionals and services. Findings illustrate the need (1) for readily available tools to help parents and professionals identify clinically significant anxiety in children, (2) to ensure that families and professionals can easily access guidance on the help-seeking process and available support, and (3) to ensure existing services offer sufficient provision for less severe difficulties that incorporates direct support for parents.

Ensuring that the poor and vulnerable population benefit from malaria control interventions remains a challenge for malaria endemic countries. Until recently, ownership and use of insecticides treated nets (ITNs) in most countries was low and inequitable, although coverage has increased in countries where free ITN distribution is integrated into mass vaccination campaigns. In Kenya, free ITNs were distributed to children aged below five years in 2006 through two mass campaigns. High and equitable coverage were reported after the campaigns in some districts, although national level coverage remained low, suggesting that understanding barriers to access remains important. This study was conducted to explore barriers to ownership and use of ITNs among the poorest populations before and after the mass campaigns, to identify strategies for improving coverage, and to make recommendations on how increased coverage levels can be sustained. The study was conducted in the poorest areas of four malaria endemic districts in Kenya. Multiple data collection methods were applied including: cross-sectional surveys (n = 708 households), 24 focus group discussions and semi-structured interviews with 70 ITN suppliers. Affordability was reported as a major barrier to access but non-financial barriers were also shown to be important determinants. On the demand side key barriers to access included: mismatch between the types of ITNs supplied through interventions and community preferences; perceptions and beliefs on illness causes; physical location of suppliers and; distrust in free delivery and in the distribution agencies. Key barriers on the supply side included: distance from manufacturers; limited acceptability of ITNs provided through interventions; crowding out of the commercial sector and the price. Infrastructure, information and communication played a central role in promoting or hindering access. Significant resources have been directed towards addressing affordability barriers through providing free ITNs to vulnerable groups, but the success of these interventions depends largely on the degree to which other barriers to access are addressed. Only if additional efforts are directed towards addressing non-financial barriers to access, will high coverage levels be achieved and sustained.

The Philosophy of User Interfaces in HELIO and the Importance of CASSIS
NASA Astrophysics Data System (ADS)
Bonnin, X.; Aboudarham, J.; Renié, C.; Csillaghy, A.; Messerotti, M.; Bentley, R. D.
2012-09-01
HELIO is a European project funded under FP7 (Project No. 238969). One of its goals as a Heliospheric Virtual Observatory is to provide an easy access to many datasets scattered all over the world, in the fields of Solar physics, Heliophysics, and Planetary magnetospheres. The efficiency of such a tool is very much related to the quality of the user interface. HELIO infrastructure is based on a Service Oriented Architecture (SOA), regrouping a network of standalone components, which allows four main types of interfaces: - HELIO Front End (HFE) is a browser-based user interface, which offers a centralized access to the HELIO main functionalities. Especially, it provides the possibility to reach data directly, or to refine selection by determination of observing characteristics, such as which instrument was observing at that time, which instrument was at this location, etc. - Many services/components provide their own standalone graphical user interface. While one can directly access individually each of these interfaces, they can also be connected together. - Most services also provide direct access for any tools through a public interface. A small java library, called Java API, simplifies this access by providing client stubs for services and shields the user from security, discovery and failover issues. - Workflows capabilities are available in HELIO, allowing complex combination of queries over several services. We want the user to be able to navigate easily, at his needs, through the various interfaces, and possibly use a specific one in order to make much-dedicated queries. We will also emphasize the importance of the CASSIS project (Coordination Action for the integration of Solar System Infrastructure and Science) in encouraging the interoperability necessary to undertake scientific studies that span disciplinary boundaries. If related projects follow the guidelines being developed by CASSIS then using external resources with HELIO will be greatly simplified.

The design and features of a high pressure chamber and burner that is suitable for combustion experiments at elevated pressures are presented. The high pressure combustion apparatus utilizes a high pressure burner that is comprised of a chamber burner module and an easily accessible interchangeable burner module to add to its flexibility. The burner is well suited to study both premixed and non-premixed flames. The optical access to the chamber is provided through four viewports for direct visual observations and optical-based diagnostic techniques. Auxiliary features include numerous access ports and electrical connections and as a result, the combustion apparatus is also suitable to work with plasmas and liquid fuels. Images of methane flames at elevated pressures up to 25 atm and preliminary results of optical-based measurements demonstrate the suitability of the high pressure experimental apparatus for combustion experiments.

Over the past several years, much attention has been focused on the human exploration of near-Earth asteroids (NEAs). Two independent NASA studies examined the feasibility of sending piloted missions to NEAs [1, 2], and in 2009, the Augustine Commission identified NEAs as high profile destinations for human exploration missions beyond the Earth-Moon system [3]. More recently the current U.S. presidential administration directed NASA to include NEAs as destinations for future human exploration with the goal of sending astronauts to a NEA in the mid to late 2020s. This directive became part of the official National Space Policy of the United States of America as of June 28, 2010 [4]. Detailed planning for such deep space exploration missions and identifying potential NEAs as targets for human spaceflight requires selecting objects from the ever growing list of newly discovered NEAs. Hence NASA developed and implemented the Near-Earth Object (NEO) Human Space Flight (HSF) Accessible Target Study (NHATS), which identifies potential candidate objects on the basis of defined dynamical trajectory performance constraints.

1991-01-01
The results of applications research directed at finding an improved method of storing and accessing information are presented. Twelve microcomputer-based expert systems shells and five laser-optical formats have been studied, and the general and specific methods of interfacing these technologies are being tested in prototype systems. Shell features and interfacing capabilities are discussed, and results from the study of five laser-optical formats are recounted including the video laser, compact, and WORM disks, and laser cards and film. Interfacing, including laser disk device driver interfacing, is discussed and it is pointed out that in order to control the laser device from within the expert systems application, the expert systems shell must be able to access the device driver software. Potential integrated applications are investigated and an initial list is provided including consumer services, travel, law enforcement, human resources, marketing, and education and training.

Differential processing of consonants and vowels in lexical access through reading.
New, Boris; Araújo, Verónica; Nazzi, Thierry
2008-12-01
Do consonants and vowels have the same importance during reading? Recently, it has been proposed that consonants play a more important role than vowels for language acquisition and adult speech processing. This proposal has started receiving developmental support from studies showing that infants are better at processing specific consonantal than vocalic information while learning new words. This proposal also received support from adult speech processing. In our study, we directly investigated the relative contributions of consonants and vowels to lexical access while reading by using a visual masked-priming lexical decision task. Test items were presented following four different primes: identity (e.g., for the word joli, joli), unrelated (vabu), consonant-related (jalu), and vowel-related (vobi). Priming was found for the identity and consonant-related conditions, but not for the vowel-related condition. These results establish the privileged role of consonants during lexical access while reading.

Study on the feasibility of provision of distance learning programmes in surgery to Malawi.
Mains, Edward A A; Blackmur, James P; Dewhurst, David; Ward, Ross M; Garden, O James; Wigmore, Stephen J
2011-12-01
Medical educational opportunities and resources are considerably limited in the developing world. The expansion of computing and Internet access means that there exists a potential to provide education to students through distance learning programmes. This study investigated the feasibility of providing distance learning course in surgery in Malawi. The study investigated the user requirements, technical requirements and Internet connections in two teaching hospitals in Malawi. In addition the appropriateness of current course material from the Edinburgh Surgical Sciences Qualification to Malawi trainees was assessed. The study found a high degree of interest from Malawian trainees in distance learning. The provision of basic science modules such as anatomy and physiology and the ability to access journals were considered highly desirable. The current ESSQ course would require extensive re-modelling to make it suitable to an African trainee's requirements. Internet speeds remain slow and access is currently expensive. There is considerable interest in distance learning programmes in Malawi but access to them is limited partly because of slow and expensive Internet access. Understanding the needs of trainees in countries such as Malawi will allow better direction of educational aid and resources to support surgical training.

Accessible engineering drawings for visually impaired machine operators.
Ramteke, Deepak; Kansal, Gayatri; Madhab, Benu
2014-01-01
An engineering drawing provides manufacturing information to a machine operator. An operator plans and executes machining operations based on this information. A visually impaired (VI) operator does not have direct access to the drawings. Drawing information is provided to them verbally or by using sample parts. Both methods have limitations that affect the quality of output. Use of engineering drawings is a standard practice for every industry; this hampers employment of a VI operator. Accessible engineering drawings are required to increase both independence, as well as, employability of VI operators. Today, Computer Aided Design (CAD) software is used for making engineering drawings, which are saved in CAD files. Required information is extracted from the CAD files and converted into Braille or voice. The authors of this article propose a method to make engineering drawings information directly accessible to a VI operator.

Kinds of access: different methods for report reveal different kinds of metacognitive access
Overgaard, Morten; Sandberg, Kristian
2012-01-01
In experimental investigations of consciousness, participants are asked to reflect upon their own experiences by issuing reports about them in different ways. For this reason, a participant needs some access to the content of her own conscious experience in order to report. In such experiments, the reports typically consist of some variety of ratings of confidence or direct descriptions of one's own experiences. Whereas different methods of reporting are typically used interchangeably, recent experiments indicate that different results are obtained with different kinds of reporting. We argue that there is not only a theoretical, but also an empirical difference between different methods of reporting. We hypothesize that differences in the sensitivity of different scales may reveal that different types of access are used to issue direct reports about experiences and metacognitive reports about the classification process.

Direct restoration of endodontically treated maxillary central incisors: post or no post at all?
von Stein-Lausnitz, Manja; Bruhnke, M; Rosentritt, M; Sterzenbach, G; Bitter, K; Frankenberger, R; Naumann, M
2018-04-30
The aim of this ex-vivo study was to evaluate the impact of cavity size and glass-fiber post (GFP) placement on the load capability of endodontically treated maxillary incisors directly restored with resin composite. Ninety-six extracted human maxillary central incisors were endodontically treated and distributed to four groups (n = 24): access cavity (A), access cavity and uni-proximal class III cavity (U), access cavity and bi-proximal class III cavity (B), and decoronated tooth (D). Specimens were restored with resin composite, and 12 specimen of each group received an adhesively placed glass-fiber post (P). Prior to linear loading, specimens were exposed to thermo-mechanical loading (TCML). Statistical analysis was performed using log-rank test after TCML, Kruskall-Wallis and Mann-Whitney U test to compare load capabilities (F max) . Significantly more failures occurred in group D for specimens without GFP during TCML (p = 0.001). F max (mean (SD) in N was (A) 513 (124), (AP) 554 (201), (U) 438 (171), (UP) 537 (232) (B) 483 (219), (BP) 536 (281), D 143 (181), and DP 500 (331), and differed significantly among groups (p = 0.003). Pair-wise comparison revealed lower F max values for group D compared to all other groups (p < 0.034) except group DP. Endodontically treated maxillary central incisors with cavity sizes up to bi-proximal class III may be successfully directly restored with resin composite. Post placement shows no additional effect except for decoronated endodontically treated incisors. Endodontically treated incisors with access cavities to class III cavities can be successfully restored with resin composite. Post placement for decoronated ETT is recommended.

Barriers and facilitators to using NHS Direct: a qualitative study of 'users' and 'non-users'.
Cook, Erica J; Randhawa, Gurch; Large, Shirley; Guppy, Andy; Chater, Angel M; Ali, Nasreen
2014-10-25
NHS Direct, introduced in 1998, has provided 24/7 telephone-based healthcare advice and information to the public in England and Wales. National studies have suggested variation in the uptake of this service amongst the UK's diverse population. This study provides the first exploration of the barriers and facilitators that impact upon the uptake of this service from the perspectives of both 'users' and 'non- users'. Focus groups were held with NHS Direct 'users' (N = 2) from Bedfordshire alongside 'non-users' from Manchester (N = 3) and Mendip, Somerset (N = 4). Each focus group had between five to eight participants. A total of eighty one people aged between 21 and 94 years old (M: 58.90, SD: 22.70) took part in this research. Each focus group discussion lasted approximately 90 minutes and was audiotape-recorded with participants' permission. The recordings were transcribed verbatim. A framework approach was used to analyse the transcripts. The findings from this research uncovered a range of barriers and facilitators that impact upon the uptake of NHS Direct. 'Non-users' were unaware of the range of services that NHS Direct provided. Furthermore, 'non-users' highlighted a preference for face-to face communication, identifying a lack of confidence in discussing healthcare over the telephone. This was particularly evident among older people with cognitive difficulties. The cost to telephone a '0845' number from a mobile was also viewed to be a barrier to access NHS Direct, expressed more often by 'non-users' from deprived communities. NHS Direct 'users' identified that awareness, ease of use and convenience were facilitators which influenced their decision to use the service. An understanding of the barriers and facilitators which impact on the access and uptake of telephone-based healthcare is essential to move patients towards the self-care model. This research has highlighted the need for telephone-based healthcare services to increase public awareness; through the delivery of more targeted advertising to promote the service provision available.

Background Low fruit and vegetable ( FV) consumption is a key risk factor for morbidity and mortality. Consumption of FV is limited by a lack of access to FV. Enhanced understanding of interventions and their impact on both access to and consumption of FV can provide guidance to public health decision-makers. The purpose of this scoping review is to identify and map literature that has evaluated effects of community-based interventions designed to increase FV access or consumption among five to 18-year olds. Methods The search included 21 electronic bibliographic databases, grey literature, targeted organization websites, and 15 key journals for relevant studies published up to May 2011. Retrieved citations were screened in duplicate for relevance. Data extracted from included studies covered: year, country, study design, target audience, intervention setting, intervention strategies, interventionists, and reported outcomes. Results The search located 19,607 unique citations. Full text relevance screening was conducted on 1,908 studies. The final 289 unique studies included 30 knowledge syntheses, 27 randomized controlled trials, 55 quasi-experimental studies, 113 cluster controlled studies, 60 before-after studies, one mixed method study, and three controlled time series studies. Of these studies, 46 included access outcomes and 278 included consumption outcomes. In terms of target population, 110 studies focused on five to seven year olds, 175 targeted eight to 10 year olds, 192 targeted 11 to 14 year olds, 73 targeted 15 to 18 year olds, 55 targeted parents, and 30 targeted teachers, other service providers, or the general public. The most common intervention locations included schools, communities or community centres, and homes. Most studies implemented multi-faceted intervention strategies to increase FV access or consumption. Conclusions While consumption measures were commonly reported, this review identified a small yet important subset of literature examining access to FV. This is a critically important issue since consumption is contingent upon access. Future research should examine the impact of interventions on direct outcome measures of FV access and a focused systematic review that examines these interventions is also needed. In addition, research on interventions in low- and middle-income countries is warranted based on a limited existing knowledge base. PMID:22931474

Evaluate the quality, accessibility and presence of Web 2.0 tools in the Andalusia Public Health System hospitals websites Observational, descriptive study carried out between 2010 and 2012. The variables analyzed were: quality, accessibility and innovation. The quality was evaluated using a Bermudez-Tamayo questionnaire. Accessibility was measured using the Web Accessibility Test (TAW) tool. Web 2.0 tools were identified by direct observation. A total of 31 of the 45 hospitals (68.9%) had a website in the year 2010, increasing to 34 (75.5%) in 2012. The average score+standard deviation (SD) of the Bermudez-Tamayo quality questionnaire was 11.1+3.8 points in 2010, and 12.3+3.9 points in 2012, observing a statistically significant difference of 0.25 being observed between the means (P=.007), 95% CI; 0.00 to 0.50) In the accessibility evaluation only 7 websites (n=31) in 2010, and 10 (n=34) in 2012, fulfilled the legal criteria for accessibility. The use of Web 2.0 tools has increased throughout the study. In 2010, 19.4% (n=6) of the hospital websites had this type of tool, in comparison to 58.8% (n=20) in 2012. In general, the quality of the websites studied is good. However, current legislation regarding accessibility is not fulfilled and must be revised and adapted to the current legal rules. There is an incipient use of Web 2.0 resources as education and communication strategies with regard to health. Copyright © 2013 SECA. Published by Elsevier Espana. All rights reserved.

The aim of this study was to close ventricular septal defects (VSDs) directly through the chest wall using magnetic resonance imaging (MRI) guidance, without cardiopulmonary bypass, sternotomy, or radiation exposure. Surgical, percutaneous, and hybrid management of VSD each have limitations and known morbidity. Percutaneous muscular VSDs were created in 10 naive Yorkshire swine using a transjugular laser catheter. Under real-time MRI guidance, a direct transthoracic vascular access sheath was introduced through the chest into the heart along a trajectory suitable for VSD access and closure. Through this transthoracic sheath, muscular VSDs were occluded using a commercial nitinol device. Finally, the right ventricular free wall was closed using a commercial collagen plug intended for arterial closure. Anterior, posterior, and mid-muscular VSDs (6.8 ± 1.8 mm) were created. VSDs were closed successfully in all animals. The transthoracic access sheath was displaced in 2, both fatal. Thereafter, we tested an intracameral retention sheath to prevent this complication. Right ventricular access ports were closed successfully in all, and after as many as 30 days, healed successfully. Real-time MRI guidance allowed closed-chest transthoracic perventricular muscular VSD closure in a clinically meaningful animal model. Once applied to patients, this approach may avoid traditional surgical, percutaneous, or open-chest transcatheter ("hybrid") risks. Copyright © 2011 American College of Cardiology Foundation.

Diagnostic and therapeutic direct peroral cholangioscopy using an intraductal anchoring balloon
Parsi, Mansour A; Stevens, Tyler; Vargo, John J
2012-01-01
AIM: To report our experience using a recently introduced anchoring balloon for diagnostic and therapeutic direct peroral cholangioscopy (DPOC). METHODS: Consecutive patients referred for diagnostic or therapeutic peroral cholangioscopy were evaluated in a prospective cohort study. The patients underwent DPOC using an intraductal anchoring balloon, which was recently introduced to allow consistent access to the biliary tree with an ultraslim upper endoscope. The device was later voluntarily withdrawn from the market by the manufacturer. RESULTS: Fourteen patients underwent DPOC using the anchoring balloon. Biliary access with an ultraslim upper endoscope was accomplished in all 14 patients. In 12 (86%) patients, ductal access required sphincteroplasty with a 10-mm dilating balloon. Intraductal placement of the ultraslim upper endoscope allowed satisfactory visualization of the biliary mucosa to the level of the confluence of the right and left hepatic ducts in 13 of 14 patients (93%). Therapeutic interventions by DPOC were successfully completed in all five attempted cases (intraductal biopsy in one and DPOC guided laser lithotripsy in four). Adverse events occurred in a patient on immunosuppressive therapy who developed an intrahepatic biloma at the site of the anchoring balloon. This required hospitalization and antibiotics. Repeat endoscopic retrograde cholangiopancreatography 8 wk after the index procedure showed resolution of the biloma. CONCLUSION: Use of this anchoring balloon allowed consistent access to the biliary tree for performance of diagnostic and therapeutic DPOC distal to the biliary bifurcation. PMID:22912549

The purpose of the study was to determine from whom and where adolescents obtained tobacco, including cigarettes, e-cigarettes, and hookah. California adolescents (N = 772; 63.19% female; mean age = 16.13 years, SD = 1.61; 26.44% white, 22.12% Asian/Pacific Islander, 36.65% Hispanic, and 14.79% other) were surveyed about their access to different tobacco products. Adolescents were significantly more likely to obtain tobacco from friends (54.9%) than family members or direct purchasing (p < .001). Smoke shops were the most common purchase location across products (44.3%), with adolescents significantly more likely to purchase hookah and e-cigarettes from smoke shops than gas stations, liquor stores, or drug stores (p < .02). The effective characterization of tobacco access patterns is critical to the development of comprehensive tobacco control. By demonstrating peers and smoke shops as the primary social and retail outlets, this study identifies targets for the optimization of regulation and messaging aimed at reducing adolescents' access to tobacco.

Direct-access retrieval during sentence comprehension: Evidence from Sluicing
Martin, Andrea E.; McElree, Brian
2011-01-01
Language comprehension requires recovering meaning from linguistic form, even when the mapping between the two is indirect. A canonical example is ellipsis, the omission of information that is subsequently understood without being overtly pronounced. Comprehension of ellipsis requires retrieval of an antecedent from memory, without prior prediction, a property which enables the study of retrieval in situ (Martin & McElree, 2008, 2009). Sluicing, or inflectional phrase ellipsis, in the presence of a conjunction, presents a test case where a competing antecedent position is syntactically licensed, in contrast with most cases of nonadjacent dependency, including verb phrase ellipsis. We present speed-accuracy tradeoff and eye-movement data inconsistent with the hypothesis that retrieval is accomplished via a syntactically guided search, a particular variant of search not examined in past research. The observed timecourse profiles are consistent with the hypothesis that antecedents are retrieved via a cue-dependent direct-access mechanism susceptible to general memory variables. PMID:21580797

Filter Bank Multicarrier (FBMC) for long-reach intensity modulated optical access networks
NASA Astrophysics Data System (ADS)
Saljoghei, Arsalan; Gutiérrez, Fernando A.; Perry, Philip; Barry, Liam P.
2017-04-01
Filter Bank Multi Carrier (FBMC) is a modulation scheme which has recently attracted significant interest in both wireless and optical communications. The interest in optical communications arises due to FBMC's capability to operate without a Cyclic Prefix (CP) and its high resilience to synchronisation errors. However, the operation of FBMC in optical access networks has not been extensively studied either in downstream or upstream. In this work we use experimental work to investigate the operation of FBMC in intensity modulated Passive Optical Networks (PONs) employing direct detection in conjunction with both direct and external modulation schemes. The data rates and propagation lengths employed here vary from 8.4 to 14.8 Gb/s and 0-75 km. The results suggest that by using FBMC it is possible to accomplish CP-Less transmission up to 75 km of SSMF in passive links using cost effective intensity modulation and detection schemes.

Corporatization of pain medicine: implications for widening pain care disparities.
Meghani, Salimah H
2011-04-01
The current health care system in the United States is structured in a way that ensures that more opportunity and resources flow to the wealthy and socially advantaged. The values intrinsic to the current profit-oriented culture are directly antithetical to the idea of equitable access. A large body of literature points to disparities in pain treatment and pain outcomes among vulnerable groups. These disparities range from the presence of disproportionately higher numbers and magnitude of risk factors for developing disabling pain, lack of access to primary care providers, analgesics and interventions, lack of referral to pain specialists, longer wait times to receive care, receipt of poor quality of pain care, and lack of geographical access to pharmacies that carry opioids. This article examines the manner in which the profit-oriented culture in medicine has directly and indirectly structured access to pain care, thereby widening pain treatment disparities among vulnerable groups. Specifically, the author argues that the corporatization of pain medicine amplifies disparities in pain outcomes in two ways: 1) directly through driving up the cost of pain care, rendering it inaccessible to the financially vulnerable; and 2) indirectly through an interface with corporate loss-aversion/risk management culture that draws upon irrelevant social characteristics, thus worsening disparities for certain populations. Thus, while financial vulnerability is the core reason for lack of access, it does not fully explain the implications of corporate microculture regarding access. The effect of corporatization on pain medicine must be conceptualized in terms of overt access to facilities, providers, pharmaceuticals, specialty services, and interventions, but also in terms of the indirect or covert effect of corporate culture in shaping clinical interactions and outcomes.

Direct-To-Consumer Telehealth May Increase Access To Care But Does Not Decrease Spending.
Ashwood, J Scott; Mehrotra, Ateev; Cowling, David; Uscher-Pines, Lori
2017-03-01
The use of direct-to-consumer telehealth, in which a patient has access to a physician via telephone or videoconferencing, is growing rapidly. A key attraction of this type of telehealth for health plans and employers is the potential savings involved in replacing physician office and emergency department visits with less expensive virtual visits. However, increased convenience may tap into unmet demand for health care, and new utilization may increase overall health care spending. We used commercial claims data on over 300,000 patients from three years (2011-13) to explore patterns of utilization and spending for acute respiratory illnesses. We estimated that 12 percent of direct-to-consumer telehealth visits replaced visits to other providers, and 88 percent represented new utilization. Net annual spending on acute respiratory illness increased $45 per telehealth user. Direct-to-consumer telehealth may increase access by making care more convenient for certain patients, but it may also increase utilization and health care spending.

Indoor localization of persons and objects poses a great engineering challenge. Previously developed localization systems demonstrate the use of wideband techniques in ultrasound ranging systems. Direct sequence and frequency hopping spread spectrum ultrasound signals have been proven to achieve a high level of accuracy. A novel ranging method using the frequency hopping spread spectrum with finite impulse response filtering will be investigated and compared against the direct sequence spread spectrum. In the first setup, distances are estimated in a single-access environment, while in the second setup, two senders and one receiver are used. During the experiments, the micro-electromechanical systems are used as ultrasonic sensors, while the senders were implemented using field programmable gate arrays. Results show that in a single-access environment, the direct sequence spread spectrum method offers slightly better accuracy and precision performance compared to the frequency hopping spread spectrum. When two senders are used, measurements point out that the frequency hopping spread spectrum is more robust to near-far effects than the direct sequence spread spectrum. PMID:24553084

Non-contact data access with direction identification for industrial differential serial bus
NASA Astrophysics Data System (ADS)
Xie, Kai; Li, Xiaoping; Zhang, Hanlu; Yang, Ming; Ye, Yinghao
2013-06-01
We propose a non-contact method for accessing data in industrial differential serial bus applications, which could serve as an effective and safe online testing and diagnosing tool. The data stream and the transmission direction are reconstructed simultaneously from the near-field emanations of a twisted pair, eliminating direct contact with the actual conductors, and avoiding damage to the insulation (only the outer sheathing is removed). A non-contact probe with the ability to sense electric and magnetic fields is presented, as are theories for data reconstruction, direction identification, and a circuit implementation. The prototype was built using inexpensive components and then tested on a standard RS-485 industrial serial bus. Experimental results verified the validity of the proposed scheme.

Dynamic Kinetic Asymmetric Transformations of β-Stereogenic-α-Keto Esters via Direct Aldolization
Corbett, Michael T.; Johnson, Jeffrey S.
2014-01-01
Dynamic kinetic asymmetric transformations (DyKAT) of racemic β-bromo-α-keto esters via direct aldolization of nitromethane and acetone provide access to fully substituted α-glycolic acid derivatives bearing a β-stereocenter. The aldol adducts are obtained in excellent yield with high relative and absolute stereocontrol under mild reaction conditions. Mechanistic studies determined that the reactions proceed through a facile catalyst-mediated racemization of the β-bromo-α-keto esters under a DyKAT Type I manifold. PMID:24222195

Intersystem Interference Reduction for Overlaid HAPS-Terrestrial CDMA System
NASA Astrophysics Data System (ADS)
Huang, Jeng-Ji; Wang, Wei-Ting; Li, Mingfu; Shiung, David; Ferng, Huei-Wen
In this letter, we propose that directional antennas, combined with power management, be incorporated to reduce intersystem interference in a shared band overlaid high altitude platform station (HAPS)-terrestrial code division multiple access (CDMA) system. To eliminate the HAPS to terrestrial interference, the HAPS is accessed only via directional antennas under the proposed scheme. By doing so, the uplink power to the HAPS can accordingly be increased, so that the terrestrial to HAPS interference is also effectively suppressed.

Percutaneous transfacial direct embolization of an intraosseous dural arteriovenous fistula.
Nerva, John D; Hallam, Danial K; Ghodke, Basavaraj V
2014-03-01
An intraosseous dural arteriovenous fistula (DAVF) is a rare cerebrovascular disease. The fistulous connection occurs within intraosseous diploic or transosseous emissary veins causing dilated intraosseous vascular pouches. To the authors' knowledge, this report describes the first percutaneous transfacial direct embolization of an intraosseous DAVF. A man in his 50s with blue rubber bleb nevus syndrome presented with headaches, imbalance, decreased visual acuity bilaterally, and left eye proptosis and chemosis. Imaging demonstrated an extensive intraosseous DAVF with dilated intraosseous vascular pouches throughout his cranial base and intraorbital venous congestion. He underwent staged endovascular treatment with the goal to improve his ocular symptoms. Transarterial and transvenous approaches failed to provide adequate access to the intraosseous vascular pouches. A direct, percutaneous transfacial approach was used to access the pouches for embolization with coils and liquid embolic material. Postoperative angiography demonstrated successful embolization of the pouch within the left pterygoid wing, reduced opacification of the intraosseous fistula, and elimination of intraorbital venous congestion. At 9-month follow-up, the patient's headaches had resolved, and his ocular symptomatology had improved. Endovascular access to an intraosseous DAVF is limited by the size and location of the intraosseous vascular pouches. In this case, a direct transfacial approach under image guidance facilitated access and embolization, which led to an improvement in the patient's symptoms. This technique is a novel approach for DAVF management.

2014-01-01
To describe patient-reported access to primary health care across 4 organizational models of primary care in Ontario, and to explore how access is associated with patient, provider, and practice characteristics. Cross-sectional survey. One hundred thirty-seven randomly selected primary care practices in Ontario using 1 of 4 delivery models (fee for service, established capitation, reformed capitation, and community health centres). Patients included were at least 18 years of age, were not severely ill or cognitively impaired, were not known to the survey administrator, had consenting providers at 1 of the participating primary care practices, and were able to communicate in English or French either directly or through a translator. Patient-reported access was measured by a 4-item scale derived from the previously validated adult version of the Primary Care Assessment Tool. Questions were asked about physician availability during and outside of regular office hours and access to health information via telephone. Responses to the scale were normalized, with higher scores reflecting greater patient-reported access. Linear regressions were used to identify characteristics independently associated with access to care. Established capitation model practices had the highest patient-reported access, although the difference in scores between models was small. Our multilevel regression model identified several patient factors that were significantly (P = .05) associated with higher patient-reported access, including older age, female sex, good-to-excellent self-reported health, less mental health disability, and not working. Provider experience (measured as years since graduation) was the only provider or practice characteristic independently associated with improved patient-reported access. This study adds to what is known about access to primary care. The study found that established capitation models outperformed all the other organizational models, including reformed capitation models, independent of provider and practice variables save provider experience. This suggests that the capitation models might provide better access to care and that it might take time to realize the benefits of organizational reforms.

This article considers a quaternary direct-sequence code-division multiple-access (DS-CDMA) communication system with asymmetric quadrature phase-shift-keying (AQPSK) modulation for unequal error protection (UEP) capability. Both time synchronous and asynchronous cases are investigated. An expression for the probability distribution of the multiple-access interference is derived. The exact bit-error performance and the approximate performance using a Gaussian approximation and random signature sequences are evaluated by extending the techniques used for uniform quadrature phase-shift-keying (QPSK) and binary phase-shift-keying (BPSK) DS-CDMA systems. Finally, a general system model with unequal user power and the near-far problem is considered and analyzed. The results show that, for a system with UEP capability, the less protected data bits are more sensitive to the near-far effect that occurs in a multiple-access environment than are the more protected bits.

Peer-to-peer architecture for multi-departmental distributed PACS
NASA Astrophysics Data System (ADS)
Rosset, Antoine; Heuberger, Joris; Pysher, Lance; Ratib, Osman
2006-03-01
We have elected to explore peer-to-peer technology as an alternative to centralized PACS architecture for the increasing requirements for wide access to images inside and outside a radiology department. The goal being to allow users across the enterprise to access any study anytime without the need for prefetching or routing of images from central archive. Images can be accessed between different workstations and local storage nodes. We implemented "bonjour" a new remote file access technology developed by Apple allowing applications to share data and files remotely with optimized data access and data transfer. Our Open-source image display platform called OsiriX was adapted to allow sharing of local DICOM images through direct access of each local SQL database to be accessible from any other OsiriX workstation over the network. A server version of Osirix Core Data database also allows to access distributed archives servers in the same way. The infrastructure implemented allows fast and efficient access to any image anywhere anytime independently from the actual physical location of the data. It also allows benefiting from the performance of distributed low-cost and high capacity storage servers that can provide efficient caching of PACS data that was found to be 10 to 20 x faster that accessing the same date from the central PACS archive. It is particularly suitable for large hospitals and academic environments where clinical conferences, interdisciplinary discussions and successive sessions of image processing are often part of complex workflow or patient management and decision making.

Intranasal administration of oxytocin: behavioral and clinical effects, a review.
Veening, Jan G; Olivier, Berend
2013-09-01
The intranasal (IN-) administration of substances is attracting attention from scientists as well as pharmaceutical companies. The effects are surprisingly fast and specific. The present review explores our current knowledge about the routes of access to the cranial cavity. 'Direct-access-pathways' from the nasal cavity have been described but many additional experiments are needed to answer a variety of open questions regarding anatomy and physiology. Among the IN-applied substances oxytocin (OT) has an extensive history. Originally applied in women for its physiological effects related to lactation and parturition, over the last decade most studies focused on their behavioral 'prosocial' effects: from social relations and 'trust' to treatment of 'autism'. Only very recently in a microdialysis study in rats and mice, the 'direct-nose-brain-pathways' of IN-OT have been investigated directly, implying that we are strongly dependent on results obtained from other IN-applied substances. Especially the possibility that IN-OT activates the 'intrinsic' OT-system in the hypothalamus as well needs further clarification. We conclude that IN-OT administration may be a promising approach to influence human communication but that the existing lack of information about the neural and physiological mechanisms involved is a serious problem for the proper understanding and interpretation of the observed effects.

A glucose meter evaluation co-designed with both health professional and consumer input.
Thompson, Harmony; Chan, Huan; Logan, Florence J; Heenan, Helen F; Taylor, Lynne; Murray, Chris; Florkowski, Christopher M; Frampton, Christopher M A; Lunt, Helen
2013-11-22
Health consumer's input into assessment of medical device safety is traditionally given either as part of study outcome (trial participants) or during post marketing surveillance. Direct consumer input into the methodological design of device assessment is less common. We discuss the difference in requirements for assessment of a measuring device from the consumer and clinician perspectives, using the example of hand held glucose meters. Around 80,000 New Zealanders with diabetes recently changed their glucose meter system, to enable ongoing access to PHARMAC subsidised meters and strips. Consumers were most interested in a direct comparison of their 'old' meter system (Accu-Chek Performa) with their 'new' meter system (CareSens brand, including the CareSens N POP), rather than comparisons against a laboratory standard. This direct comparison of meter/strip systems showed that the CareSens N POP meter read around 0.6 mmol/L higher than the Performa system. Whilst this difference is unlikely to result in major errors in clinical decision making such as major insulin dosing errors, this information is nevertheless of interest to consumers who switched meters so that they could maintain access to PHARMAC subsidised meters and strips. We recommend that when practical, the consumer perspective be incorporated into study design related to medical device assessment.

Geoscience data visualization and analysis using GeoMapApp
NASA Astrophysics Data System (ADS)
Ferrini, Vicki; Carbotte, Suzanne; Ryan, William; Chan, Samantha
2013-04-01
Increased availability of geoscience data resources has resulted in new opportunities for developing visualization and analysis tools that not only promote data integration and synthesis, but also facilitate quantitative cross-disciplinary access to data. Interdisciplinary investigations, in particular, frequently require visualizations and quantitative access to specialized data resources across disciplines, which has historically required specialist knowledge of data formats and software tools. GeoMapApp (www.geomapapp.org) is a free online data visualization and analysis tool that provides direct quantitative access to a wide variety of geoscience data for a broad international interdisciplinary user community. While GeoMapApp provides access to online data resources, it can also be packaged to work offline through the deployment of a small portable hard drive. This mode of operation can be particularly useful during field programs to provide functionality and direct access to data when a network connection is not possible. Hundreds of data sets from a variety of repositories are directly accessible in GeoMapApp, without the need for the user to understand the specifics of file formats or data reduction procedures. Available data include global and regional gridded data, images, as well as tabular and vector datasets. In addition to basic visualization and data discovery functionality, users are provided with simple tools for creating customized maps and visualizations and to quantitatively interrogate data. Specialized data portals with advanced functionality are also provided for power users to further analyze data resources and access underlying component datasets. Users may import and analyze their own geospatial datasets by loading local versions of geospatial data and can access content made available through Web Feature Services (WFS) and Web Map Services (WMS). Once data are loaded in GeoMapApp, a variety options are provided to export data and/or 2D/3D visualizations into common formats including grids, images, text files, spreadsheets, etc. Examples of interdisciplinary investigations that make use of GeoMapApp visualization and analysis functionality will be provided.

Depending on the degree to which the original study context is accessible, selective memory retrieval can be detrimental or beneficial for the recall of other memories (Bäuml & Samenieh, 2012). Prior work has shown that the detrimental effect of memory retrieval is typically recall specific and does not arise after restudy trials, whereas recall specificity of the beneficial effect has not been examined to date. Addressing the issue, we compared in 2 experiments the effects of retrieval and restudy on recall of other items, when access to the study context was (largely) maintained and when access to the study context was impaired (in Experiment 1 by using the listwise directed-forgetting task, in Experiment 2 by using a prolonged retention interval). In both experiments, selective retrieval but not restudy induced forgetting of other items when context access was maintained, which replicates prior work. In contrast, when context access was impaired, both selective retrieval and restudy induced beneficial effects on other memories. These findings suggest that the detrimental but not the beneficial effect of selective memory retrieval is recall specific. The results are consistent with a recent 2-factor account of selective memory retrieval that attributes the detrimental effect to inhibition or blocking but the beneficial effect to context reactivation processes.

Predator Diversity Effects in an Exotic Freshwater Food Web
Naddafi, Rahmat; Rudstam, Lars G.
2013-01-01
Cascading trophic interactions are often defined as the indirect effects of a predator on primary producers through the effect of the predator on herbivores. These effects can be both direct through removal of herbivores [density-mediated indirect interactions (DMIIs)] or indirect through changes in the behavior of the herbivores [trait-mediated indirect interactions (TMIIs)]. How the relative importance of these two indirect interactions varies with predator diversity remains poorly understood. We tested the effect of predator diversity on both TMIIs and DMIIs on phytoplankton using two competitive invasive dreissenid mussel species (zebra mussel and quagga mussel) as the herbivores and combinations of one, two or all three species of the predators pumpkinseed sunfish, round goby, and rusty crayfish. Predators had either direct access to mussels and induced both TMII and DMII, or no direct access and induced only TMII through the presence of risk cues. In both sets of treatments, the predators induced a trophic cascade which resulted in more phytoplankton remaining with predators present than with only mussels present. The trophic cascade was weaker in three-predator and two-predator treatments than in one-predator treatments when predators had direct access to dreissenids (DMIIs and TMIIs). Crayfish had higher cascading effects on phytoplankton than both pumpkinseed and round goby. Increased predator diversity decreased the strength of DMIIs but had no effect on the strength of TMIIs. The strength of TMIIs was higher with zebra than quagga mussels. Our study suggests that inter-specific interference among predators in multi-species treatments weakens the consumptive cascading effects of predation on lower trophic levels whereas the importance of predator diversity on trait mediated effects depends on predator identity.

Accessible Home Environments for People with Functional Limitations: A Systematic Review
Cho, Hea Young; MacLachlan, Malcolm; Clarke, Michael; Mannan, Hasheem
2016-01-01
The aim of this review is to evaluate the health and social effects of accessible home environments for people with functional limitations, in order to provide evidence to promote well-informed decision making for policy guideline development and choices about public health interventions. MEDLINE and nine other electronic databases were searched between December 2014 and January 2015, for articles published since 2004. All study types were included in this review. Two reviewers independently screened 12,544 record titles or titles and abstracts based on our pre-defined eligibility criteria. We identified 94 articles as potentially eligible; and assessed their full text. Included studies were critically appraised using the Mixed Method Appraisal Tool, version 2011. Fourteen studies were included in the review. We did not identify any meta-analysis or systematic review directly relevant to the question for this systematic review. A narrative approach was used to synthesise the findings of the included studies due to methodological and statistical heterogeneity. Results suggest that certain interventions to enhance the accessibility of homes can have positive health and social effects. Home environments that lack accessibility modifications appropriate to the needs of their users are likely to result in people with physical impairments becoming disabled at home. PMID:27548194

[Access control management in electronic health records: a systematic literature review].
Carrión Señor, Inmaculada; Fernández Alemán, José Luis; Toval, Ambrosio
2012-01-01
This study presents the results of a systematic literature review of aspects related to access control in electronic health records systems, wireless security and privacy and security training for users. Information sources consisted of original articles found in Medline, ACM Digital Library, Wiley InterScience, IEEE Digital Library, Science@Direct, MetaPress, ERIC, CINAHL and Trip Database, published between January 2006 and January 2011. A total of 1,208 articles were extracted using a predefined search string and were reviewed by the authors. The final selection consisted of 24 articles. Of the selected articles, 21 dealt with access policies in electronic health records systems. Eleven articles discussed whether access to electronic health records should be granted by patients or by health organizations. Wireless environments were only considered in three articles. Finally, only four articles explicitly mentioned that technical training of staff and/or patients is required. Role-based access control is the preferred mechanism to deploy access policy by the designers of electronic health records. In most systems, access control is managed by users and health professionals, which promotes patients' right to control personal information. Finally, the security of wireless environments is not usually considered. However, one line of research is eHealth in mobile environments, called mHealth. Copyright © 2011 SESPAS.

Background & Objectives : Biological disease-modifying antirheumatic drugs (bDMARDs) for the treatment of rheumatoid arthritis (RA) are not always accessible to all patients in accordance with international guidelines, partly owing to their high direct costs against a background of restricted healthcare budgets. This study compares the size of RA patient populations with access to reimbursed bDMARDs across 37 European countries, Russia, and Turkey, according to their treatment eligibility defined by European League Against Rheumatism (EULAR) recommendations and national reimbursement criteria. Methods : The size of the RA patient population eligible for bDMARD treatment was estimated in a population model using published RA epidemiological data and clinical criteria defined by 2013 EULAR recommendations along with national reimbursement criteria defined in a survey of the 39 countries in November 2015. Results : According to EULAR recommendations, 32% of the total RA population in the European region is eligible for bDMARD treatment. However, only an average 59% of this EULAR-eligible population remains eligible after applying national reimbursement criteria (from 86% in 'high access' to 13% in 'low-access' countries). Conclusion : Access to reimbursed bDMARDs remains unequal in the European region. As biosimilars of bDMARDs are introduced, changes in reimbursement criteria may increase access to bDMARDs and reduce this inequality.

We examined Mexican migrants' perceived barriers to entering substance abuse treatment and potential differences by gender. This study analyzed a subset of household data collected in Mexico in 2011 via the Encuesta Nacional de Adicciones (National Survey of Addictions). A sample of 1,143 individuals who reported using illicit drugs was analyzed using multivariate negative binomial models to determine direct and moderated relationships of gender, migrant status, and drug dependence with perceived barriers to accessing treatment. Significant findings included disparities in drug dependence by migrant status. Compared with non-migrant men, women who have traveled to the United States was associated with fewer (1.3) barriers to access treatment. Fewer barriers to access care were associated with individuals residing in other regions of the country, compared to those living in Mexico City. Drug dependence, gender, migration status and regional location are factors associated with access to needed treatment. Implications for health care policy to develop treatment services infrastructure and for future research are discussed in the context of ongoing drug policy reform in Mexico.

Summary Percutaneous injection of embolization material within head and neck tumors is being described as an alternative or adjunct to transarterial embolization. Access in these reports is by computed tomography (CT) guidance, which is cumbersome given the need to transport the patient from the CT scanner to angiography suite. We describe a case of direct percutaneous onyx embolization of juvenile nasal angiofibroma following endoscopic access in the angiography suite including self-sustained onyx combustion during surgical electrocautery.

Lipids, including the diterpenes cafestol and kahweol, are key compounds that contribute to the quality of coffee beverages. We determined total lipid content and cafestol and kahweol concentrations in green beans and genotyped 107 Coffea arabica accessions, including wild genotypes from the historical FAO collection from Ethiopia. A genome-wide association study was performed to identify genomic regions associated with lipid, cafestol and kahweol contents and cafestol/kahweol ratio. Using the diploid Coffea canephora genome as a reference, we identified 6,696 SNPs. Population structure analyses suggested the presence of two to three groups (K = 2 and K = 3) corresponding to the east and west sides of the Great Rift Valley and an additional group formed by wild accessions collected in western forests. We identified 5 SNPs associated with lipid content, 4 with cafestol, 3 with kahweol and 9 with cafestol/kahweol ratio. Most of these SNPs are located inside or near candidate genes related to metabolic pathways of these chemical compounds in coffee beans. In addition, three trait-associated SNPs showed evidence of directional selection among cultivated and wild coffee accessions. Our results also confirm a great allelic richness in wild accessions from Ethiopia, especially in accessions originating from forests in the west side of the Great Rift Valley.

2014-10-01
The current study evaluated effects of hatch moment and immediate feed and water access within a 24-h hatch window on chicken growth and development. Five hundred four male chickens obtained from a 49-wk-old Ross 308 breeder flock were assigned to 72 cages based on hatching moment (early, midterm, or late; selected during periods of 475 to 481, 483 to 487, and 489 to 493 h after onset of incubation). At the end of each hatching period, chickens were moved to the grow-out facility and one-half of the chickens received feed and water ad libitum immediately. Remaining chickens received feed and water from 504 h after onset of incubation (d 0). Body weight gain and feed intake for each cage were recorded at d 0, 1, 4, 7, 11, and 18. Chickens were sampled at d 4 and 18 for organ and carcass development. Early hatchers had lower BW at placement compared with midterm and late hatchers but compensated for this afterward, resulting in a higher BW at d 4 (112.8, 107.1, and 103.3 g, respectively). From d 0 to 18, early hatchers tended to have higher BW gain than both other groups. Relative breast meat yield at d 18, expressed as percentage of carcass weight, was higher for early (30.4%) than midterm (28.5%) and late hatchers (27.8%). Up to d 7, direct feed access resulted in higher BW gain (6.1%) and feed intake (4.2%) compared with delayed feed access. No effect of moment of feed access on feed efficiency or organ weights was found. Direct feed access resulted in a higher weight:length ratio of the jejunum (12.5%) and ileum (7.5%) at d 4 compared with delayed feed access. These results suggest that early hatchers have a different developmental and growth pattern than midterm or late hatchers within a 24-h hatch window. A mild delay in feed access after hatch affects growth and development during the first week after hatch. ©2014 Poultry Science Association Inc.

Breaking and Fixing Origin-Based Access Control in Hybrid Web/Mobile Application Frameworks.
Georgiev, Martin; Jana, Suman; Shmatikov, Vitaly
2014-02-01
Hybrid mobile applications (apps) combine the features of Web applications and "native" mobile apps. Like Web applications, they are implemented in portable, platform-independent languages such as HTML and JavaScript. Like native apps, they have direct access to local device resources-file system, location, camera, contacts, etc. Hybrid apps are typically developed using hybrid application frameworks such as PhoneGap. The purpose of the framework is twofold. First, it provides an embedded Web browser (for example, WebView on Android) that executes the app's Web code. Second, it supplies "bridges" that allow Web code to escape the browser and access local resources on the device. We analyze the software stack created by hybrid frameworks and demonstrate that it does not properly compose the access-control policies governing Web code and local code, respectively. Web code is governed by the same origin policy, whereas local code is governed by the access-control policy of the operating system (for example, user-granted permissions in Android). The bridges added by the framework to the browser have the same local access rights as the entire application, but are not correctly protected by the same origin policy. This opens the door to fracking attacks, which allow foreign-origin Web content included into a hybrid app (e.g., ads confined in iframes) to drill through the layers and directly access device resources. Fracking vulnerabilities are generic: they affect all hybrid frameworks, all embedded Web browsers, all bridge mechanisms, and all platforms on which these frameworks are deployed. We study the prevalence of fracking vulnerabilities in free Android apps based on the PhoneGap framework. Each vulnerability exposes sensitive local resources-the ability to read and write contacts list, local files, etc.-to dozens of potentially malicious Web domains. We also analyze the defenses deployed by hybrid frameworks to prevent resource access by foreign-origin Web content and explain why they are ineffectual. We then present NoFrak, a capability-based defense against fracking attacks. NoFrak is platform-independent, compatible with any framework and embedded browser, requires no changes to the code of the existing hybrid apps, and does not break their advertising-supported business model.

Weedy rice (WR) is the most significant weed in direct-seeded fields. It has morphological characteristics similar to those of cultivated rice varieties. WR is more difficult to control than other weeds. We collected WR accessions from four sites within the Pulau Pinang rice growing areas. Thirty six different accessions were collected from each site: B, the northern site; P, the central site; A, the southern site; and N, the southwestern site. Wild rice (Oryza rufipogon), which grows in the sampled areas, was also collected together with four varieties (MR84, MR185, MR211 and MR219) that have been widely planted in these areas for a long period of time. The objective of this study was to compare the morphological characteristics of the WR accessions and cultivated rice. Twenty characteristics were observed for the comparison of WR accessions and rice cultivars. Morpho-matrix analyses allowed the specimens to be grouped to two main groups (A and B), based on a 95% dissimilarity matrix. Group A was subdivided into 7 subgroups consisting of a few WR accessions, wild rice and MR211 (control), and group B was subdivided to 10 subgroups consisting of other WR accessions and the 3 other control varieties. Dendrogram analysis indicated that the morphological traits used in this study were able to differentiate among the WR accessions and the cultivars, except for rice cultivar MR211 and WRA8, which grouped together in subgroup A2. STRUCTURE program analysis indicated that all individuals were distinguishable and were divided into 18 clusters. These results suggest that some genes of the WR accessions have been influenced by commercial varieties. The information gained from this study will be useful to develop rice weed management protocols and good agricultural practices to control WR in the future.

Method for determining the composition and orientation of III-V {001} semiconductor surfaces
NASA Astrophysics Data System (ADS)
Sung, M. M.; Kim, C.; Rabalais, J. W.
1996-09-01
A method for determining the composition and orientation of III-V {001} semiconductor surfaces is presented and applications are described. The information is obtained from the techniques of time-of-flight scattering and recoiling spectrometry (TOF-SARS), using the composition from azimuth-specific elemental accessibilities (CASEA) method, and low energy electron diffraction (LEED). The azimuth-specific elemental accessibilities (ASEA) are measured experimentally and calculated from the number of accessible atoms in the unit cell and from three-dimensional trajectory simulations using the SARIC program. The in situ analyses identify the 1st-layer elemental species and determine the orientation of the reconstructed surface symmetry elements with respect to the bulk crystallographic directions. This is demonstrated for the III-V {001} compound semiconductor surfaces of GaAs and InAs in the (4 × 2) and (4 × 2) phases and InP in the (4 × 2) phase. The analyses confirm the missing-row-dimer (MRD) structure for GaAs and InAs in which the missing row direction is parallel to the direction of the 1st-layer multimers (dimers) and the missing-row-trimer-dimer (MRTD) structure for InP in which the missing row direction is perpendicular to the direction of the 1st-layer multimers (trimers).

Older Veteran Digital Disparities: Examining the Potential for Solutions Within Social Networks
Hogan, Timothy P; Richardson, Lorilei M; Cioffari-Bailiff, Lisa; Harvey, Kimberly; Houston, Thomas K
2016-01-01
Background Older adults typically have less access to the Internet than other age groups, and older Veterans may use the Internet even less due to economic and geographic reasons. Objective To explore solutions to this problem, our study examined older Veterans’ reported ability to access technology through their close social ties. Methods Data were collected via mail survey from a sample of Veterans aged 65 years and older (N=266). Results Nearly half (44.0%, 117/266) of the sample reported having no Internet access. Yet, among those without current access, older Veterans reported having a median of 5 (IQR 7) close social ties with home Internet access. These older Veterans also reported that they would feel comfortable asking a median of 2 (IQR 4) social ties for help to access the Internet, and that a median of 2 (IQR 4) social ties would directly access the Internet for the older Veteran to help with health management. Conclusions Findings suggest that even older Veterans without current Internet access have at least two social ties with home Internet who could be called upon for technology support. Thus, older Veterans may be willing to call upon these “surrogate seekers” for technology assistance and support in health management. This has implications for the digital divide, technology design, and health care policy. PMID:27881361

Objective To examine the accessibility of absolute risk in articles reporting ratio measures in leading medical journals. Design Structured review of abstracts presenting ratio measures. Setting Articles published between 1 June 2003 and 1 May 2004 in Annals of Internal Medicine, BMJ, Journal of the American Medical Association, Journal of the National Cancer Institute, Lancet, and New England Journal of Medicine. Participants 222 articles based on study designs in which absolute risks were directly calculable (61 randomised trials, 161 cohort studies). Main outcome measure Accessibility of the absolute risks underlying the first ratio measure in the abstract. Results 68% of articles (150/222) failed to report the underlying absolute risks for the first ratio measure in the abstract (range 55−81% across the journals). Among these articles, about half did report the underlying absolute risks elsewhere in the article (text, table, or figure) but half did not report them anywhere. Absolute risks were more likely to be reported in the abstract for randomised trials compared with cohort studies (62% v 21%; relative risk 3.0, 95% confidence interval 2.1 to 4.2) and for studies reporting crude compared with adjusted ratio measures (62% v 21%; relative risk 3.0, 2.1 to 4.3). Conclusion Absolute risks are often not easily accessible in articles reporting ratio measures and sometimes are missing altogether—this lack of accessibility can easily exaggerate readers' perceptions of benefit or harm.

Humans do not have direct access to retinal flow during walking
Souman, Jan L.; Freeman, Tom C.A.; Eikmeier, Verena; Ernst, Marc O.
2013-01-01
Perceived visual speed has been reported to be reduced during walking. This reduction has been attributed to a partial subtraction of walking speed from visual speed (Durgin & Gigone, 2007; Durgin, Gigone, & Scott, 2005). We tested whether observers still have access to the retinal flow before subtraction takes place. Observers performed a 2IFC visual speed discrimination task while walking on a treadmill. In one condition, walking speed was identical in the two intervals, while in a second condition walking speed differed between intervals. If observers have access to the retinal flow before subtraction, any changes in walking speed across intervals should not affect their ability to discriminate retinal flow speed. Contrary to this “direct-access hypothesis”, we found that observers were worse at discrimination when walking speed differed between intervals. The results therefore suggest that observers do not have access to retinal flow before subtraction. We also found that the amount of subtraction depended on the visual speed presented, suggesting that the interaction between the processing of visual input and of self-motion is more complex than previously proposed.

There are various techniques and approaches for lumbar interbody fusion differing in access, cage type and type of supplemental posterior instrumentation. While a transforaminal access usually includes a hemifacetectomy, the facet joint can be preserved with a more lateral extraforaminal access. The supplemental posterior instrumentation required for both fusion techniques is still debated. The purpose of the present study was to compare primary stability of the two accesses for two different cage types with none, unilateral and bilateral supplemental posterior instrumentation. Six monosegmental lumbar functional spinal units (FSUs) were included in each of the two groups, and subjected to a flexibility test. As cages, a newly designed cage was compared to a standard cage in the following states: (a) native, (b) stand-alone cage, (c) bilateral internal fixator, (d) unilateral internal fixator, (e) unilateral facetectomy+bilateral internal fixator, (f) unilateral facetectomy+unilateral internal fixator and (g) unilateral facetectomy with stand-alone cage. For comparison the range of motion was normalized to the native state and the effects of the facetectomy, cage type, and supplemental instrumentation was compared. Within the subject comparison showed a significantly higher flexibility for the unilateral facetectomy in all motion directions (p<0.001). In between subject comparison showed a significant effect of cage type on flexibility in flexion/extension (p=0.002) and lateral bending (p=0.028) but not in axial rotation (p=0.322). The type of supplemental posterior fixation had a significant effect on the flexibility in all motion directions (stand-alone>unilateral fixator>bilateral fixator). Cage design and approach type are affecting the primary stability of lumbar interbody fusion procedures while the type of posterior instrumentation is the most influencing factor.

Direct-to-consumer genetic testing: good, bad or benign?
Caulfield, T; Ries, N M; Ray, P N; Shuman, C; Wilson, B
2010-02-01
A wide variety of genetic tests are now being marketed and sold in direct-to-consumer (DTC) commercial transactions. However, risk information revealed through many DTC testing services, especially those based on emerging genome wide-association studies, has limited predictive value for consumers. Some commentators contend that tests are being marketed prematurely, while others support rapid translation of genetic research findings to the marketplace. The potential harms and benefits of DTC access to genetic testing are not yet well understood, but some large-scale studies have recently been launched to examine how consumers understand and use genetic risk information. Greater consumer access to genetic tests creates a need for continuing education for health care professionals so they can respond to patients' inquiries about the benefits, risks and limitations of DTC services. Governmental bodies in many jurisdictions are considering options for regulating practices of DTC genetic testing companies, particularly to govern quality of commercial genetic tests and ensure fair and truthful advertising. Intersectoral initiatives involving government regulators, professional bodies and industry are important to facilitate development of standards to govern this rapidly developing area of personalized genomic commerce.

Geophysical features influence the accumulation of beach debris on Caribbean islands.
Schmuck, Alexandra M; Lavers, Jennifer L; Stuckenbrock, Silke; Sharp, Paul B; Bond, Alexander L
2017-08-15
Anthropogenic beach debris was recorded during beach surveys of 24 Caribbean islands during April 2014-April 2016. Beach debris was classified according to material type (e.g., polystyrene) and item use (e.g., fishing). Geophysical features (substrate type, beach direction, and human accessibility) of sample sites were recorded in order to investigate their relationship with debris density. Results suggest the density of macro debris (items >5mm) is highest on uninhabited, sandy beaches facing a leeward direction. Higher debris quantities on inaccessible beaches may be due to less frequent beach clean ups. Frequently accessed beaches exhibited lower macro, but higher micro debris (items 1-5mm) densities, possibly due to removal of macro debris during frequent beach clean ups. This suggests that while geophysical features have some influence on anthropogenic debris densities, high debris densities are occurring on all islands within the Caribbean region regardless of substrate, beach direction, or human accessibility.

Use of certain alternative fuels in road transport in Poland
NASA Astrophysics Data System (ADS)
Gis, W.; Pielecha, J.; Waśkiewicz, J.; Gis, M.; Menes, M.
2016-09-01
The development of biomethane and hydrogen technology in the road transport in the EU countries is recommended, among the others, in the Directive of the European Parliament and of the Council 2014/94/EU of 22 October 2014. Under the provisions of the said Directive, it is recommended to EU countries to use biomethane and progressively ensure accessibility to hydrogen cars on their territories, and above all to ensure the possibility of driving hydrogen vehicles between the member States. The territorial accessibility for biomethane vehicles is determined by the availability of biomethane refuelling infrastructure in the first place in cities and then on the road network distances recommended in this directive. The territorial accessibility for hydrogen vehicles is determined by the availability of hydrogen refuelling infrastructure, in the first place along the TEN-T network. The article presents the possibilities of using these alternative fuels in Poland, presenting some of the results of research and analysis in this area.

Yep-phi, a lytic phage of Yersinia pestis, was isolated in China and is routinely used as a diagnostic phage for the identification of the plague pathogen. Yep-phi has an isometric hexagonal head containing dsDNA and a short non-contractile conical tail. In this study, we sequenced the Yep-phi genome (GenBank accession no. HQ333270) and performed proteomics analysis. The genome consists of 38 ,616 bp of DNA, including direct terminal repeats of 222 bp, and is predicted to contain 45 ORFs. Most structural proteins were identified by proteomics analysis. Compared with the three available genome sequences of lytic phages for Y. pestis, the phages could be divided into two subgroups. Yep-phi displays marked homology to the bacteriophages Berlin (GenBank accession no. AM183667) and Yepe2 (GenBank accession no. EU734170), and these comprise one subgroup. The other subgroup is represented by bacteriophage ΦA1122 (GenBank accession no. AY247822). Potential recombination was detected among the Yep-phi subgroup.

Continued development of mobile technology now allows access to information at the point-of-care. This study was conducted to evaluate the use of one such tool on a mobile device, from the carer perspective. Caregivers across 12 aged-care facilities were supplied mobile devices to access a Picture Care Plan (PCP), a specific tool designed around the role of the personal carer. An anonymous questionnaire was subsequently completed by 85 carers with questions relating to participants' experience. Perceived helpfulness of the PCP at the point-of-care was high (87%). A significant number of participants believed the use of the PCP increased resident safety and quality of care (76%). Practical components related to the carrying of the device, network speed and the requirement to maintain communication with senior members of staff to ascertain updates were also expressed by participants. Findings suggest that staff are receptive to adoption of mobile devices to access care directives at the point-of-care and that the technology is useful.

Over 90% of US hospitals provide patients with access to e-copy of their health records, but the utilization of electronic health records by the US consumers remains low. Guided by the comprehensive information-seeking model, this study used data from the National Cancer Institute's Health Information National Trends Survey 4 (Cycle 4) and examined the factors that explain the level of electronic health record use by cancer patients. Consistent with the model, individual information-seeking factors and perceptions of security and utility were associated with the frequency of electronic health record access. Specifically, higher income, prior online information seeking, interest in accessing health information online, and normative beliefs were predictive of electronic health record access. Conversely, poorer general health status and lack of health care provider encouragement to use electronic health records were associated with lower utilization rates. The current findings provide theory-based evidence that contributes to the understanding of the explanatory factors of electronic health record use and suggest future directions for research and practice.

The tradition of field-based instruction in the geoscience curriculum, which culminates in a capstone geological field camp, presents an insurmountable barrier to many disabled students who might otherwise choose to pursue geoscience careers. There is a widespread perception that success as a practicing geoscientist requires direct access to outcrops and vantage points available only to those able to traverse inaccessible terrain. Yet many modern geoscience activities are based on remotely sensed geophysical data, data analysis, and computation that take place entirely from within the laboratory. To challenge the perception of geoscience as a career option only for the able bodied, we have created the capstone Accessible Earth Study Abroad Program, an alternative to geologic field camp with a focus on modern geophysical observation systems, computational thinking, and data science. In this presentation, we will report on the theoretical bases for developing the course, our experiences in teaching the course to date, and our plan for ongoing assessment, refinement, and dissemination of the effectiveness of our efforts.

Open Access: "à consommer avec modération"
NASA Astrophysics Data System (ADS)
Mahoney, Terence J.
There is increasing pressure on academics and researchers to publish the results of their investigations in open access journals. Indeed, some funding agencies make open access publishing a basic requirement for funding projects, and the EU is considering taking firm steps in this direction. I argue that astronomy is already one of the most open of disciplines, and that access - both to the general public (in terms of a significantly growing outreach effort) and to developing countries (through efforts to provide computing facilities and Internet access, as well as schemes to provide research centres of limited resources with journals) - is becoming more and more open in a genuine and lasting way. I further argue that sudden switches to more formal kinds of open access schemes could cause irreparable harm to astronomical publishing. Several of the most prestigious astronomical research journals (e.g. MN, ApJ, AJ) have for more than a century met the publishing needs of the research community and continue to adapt successfully to changing demands on the part of that community. The after-effects of abrupt changes in publishing practices - implemented through primarily political concerns - are hard to predict and could be severely damaging. I conclude that open access, in its current acceptation, should be studied with great care and with sufficient time before any consideration is given to its implementation. If forced on the publishing and research communities, open access could well result in much more limited access to properly vetted research results.

Until April 2012, all Spanish citizens were entitled to health care and policies had been developed at national and regional level to remove potential barriers of access, however, evidence suggested problems of access for immigrants. In order to identify factors affecting immigrants' access to health care, we conducted a qualitative study based on individual interviews with healthcare managers (n=27) and professionals (n=65) in Catalonia and Andalusia, before the policy change that restricted access for some groups. A thematic analysis was carried out. Health professionals considered access to health care "easy" for immigrants and similar to access for autochthons in both regions. Clear barriers were identified to enter the health system (in obtaining the health card) and in using services, indicating a mismatch between the characteristics of services and those of immigrants. Results did not differ among regions, except for in Catalonia, where access to care was considered harder for users without a health card, due to the fees charged, and in general, because of the distance to primary health care in rural areas. In conclusion, despite the universal coverage granted by the Spanish healthcare system and developed health policies, a number of barriers in access emerged that would require implementing the existing policies. However, the measures taken in the context of the economic crisis are pointing in the opposite direction, towards maintaining or increasing barriers. Copyright © 2016 Elsevier Ireland Ltd.

PurposeThis study was designed to assess the efficacy and safety of the ExoSeal vascular closure device (VCD) to achieve hemostasis in antegrade access of the superficial femoral artery (SFA).MethodsWe retrospectively reviewed the outcome of ExoSeal VCD used for hemostasis in 110 accesses to the SFA in 93 patients between July 2011 and July 2013. All patients had patent proximal SFA based on computer tomography angiography or ultrasound duplex. Arterial calcifications at puncture site were graded using fluoroscopy. The SFA was accessed in an antegrade fashion with ultrasound or fluoroscopic guidance. In all patients, 5–7F vascular sheaths were used. The ExoSealmore » VCD was applied to achieve hemostasis at the end of the procedure. All patients were clinically examined and had ultrasound duplex exam for any puncture site complications during the 24 h postprocedure.ResultsIn all procedures, the ExoSeal was applied successfully. We did not encounter any device-related technical failure. There were four major complications in four patients (3.6 %): three pseudoaneurysms, which were treated with direct thrombin injection, and one hematoma, which necessitated transfusion of two blood units. All patients with complications were treated with anticoagulation preprocedure or received thrombolytic therapy.ConclusionsThe ExoSeal VCD can be safely used for antegrade puncture of the SFA, with a high procedural success rate (100 %) and a low rate of access site complications (3.6 %)« less

Misconceptions about case-mix payments for nursing homes.
Grimaldi, P L
1987-04-01
Despite the increasing use of case-mix payment systems for skilled and intermediate nursing home care (at least 10 state Medicaid programs have adopted or are considering adopting such a system), misconceptions about such systems still exist. Unless these inaccurate perceptions are corrected, a state may adopt a system that fails to realize its goals. Some of these misconceptions include the beliefs that case-mix payment systems: Apply to all nursing homes costs; Will benefit hospital-based facilities; Will resolve the access problems of heavy care public patients; Will result in higher statewide payment rates because patient characteristics are factored directly into the calculations. In fact, case-mix adjustments are applied only to costs that can be traced directly to patients' impairments. Nursing services and some ancillary services are dependent on case mix, while administrative and support services are largely independent of case mix. Capital costs usually can be ignored in formulating the case-mix adjustment. Although hospital-based facilities frequently have sicker patients than freestanding facilities, studies show that only a portion of the cost differential is explained by case-mix differences. In the case of heavy-care patients, some believe that case-mix payment systems will resolve access problems by paying higher rates in response to the higher treatment costs. Access may not improve, however, if the new rates are lower than those paid by comparable private patients. Perhaps a loosening in the certificate-of-need process will also be needed to resolve the access problem.(ABSTRACT TRUNCATED AT 250 WORDS)

This prospective study aimed to compare serology for Helicobacter pylori with two, symptom questionnaires in screening patients before direct access endoscopy. Methods were compared in terms of the number of endoscopies saved and pathology missed in 315 patients referred to a gastroenterology unit by 65 local GPs. The serology used was based on an acid glycine extract of H pylori. One in-house questionnaire was based on the Glasgow dyspepsia (GLADYS) system and the other questionnaire was that reported by Holdstock et al. A cut off point of 6.3 U/ml for H pylori serology was selected for screening patients (97% sensitive and 75% specific). Serology was combined with a history of NSAID usage in determining who should have endoscopy. For the in-house questionnaire, a cut off score of more than 8 out of a possible maximum of 18 was chosen, after prior evaluation in 118 patients referred for direct access endoscopy (the sensitivity for detection of peptic ulcer was 88%, specificity 61%). A cut off score of more than 412 was used for the Holdstock questionnaire. In patients under 45 years, serology detected more peptic ulcers than the in-house questionnaire and the Holdstock questionnaire (27/28 v 24/28, NS and v 20/28, p < 0.05 respectively). The Holdstock questionnaire saved significantly more endoscopies than the other two methods (76/149 v 57/149 for the in-house questionnaire, p = 0.05 and 59/149 for serology, p = 0.05). In all age groups combined, serology was significantly better than the in-house and Holdstock questionnaires at detecting peptic ulcers and gastric cancer (61/63, 52/63, p<0.02, and 50/63, p<0.01 respectively). But serology saved significantly fewer endoscopies (89/315, 135/315, p<0.005, and 119/315, p<0.05 respectively). Serology was inferior to the Holdstock questionnaire at detecting severe oesophagitis. It is concluded that serology is the method of choice in screening before direct access upper gastrointestinal endoscopy in those under 45 years. It best combines a high sensitivity for peptic ulcer disease with a large reduction in unnecessary negative endoscopies.

Background Although literature has associated geodemographic factors with healthcare service utilization, little is known about how these factors — such as population size, age profile, service accessibility, and educational profile — interact to influence service utilization. This study fills this gap in the literature by examining both the direct and the moderating effects of geodemographic profiles on the utilization of cardiac surgery services. Methods We aggregated secondary data obtained from Statistics Canada and Cardiac Care Network of Ontario to derive the geodemographic profiles of Ontario and the corresponding cardiac surgery service utilization in the years between 2004 and 2007. We conducted a two-step test using Partial Least Squares-based structural equation modeling to investigate the relationships between geodemographic profiles and healthcare service utilization. Results Population size and age profile have direct positive effects on service utilization (β=0.737, p<0.01; β=0.284, p<0.01, respectively), whereas service accessibility is negatively associated with service utilization (β=−0.210, p<0.01). Service accessibility decreases the effect of population size on service utilization (β=−0.606, p<0.01), and educational profile weakens the effects of population size and age profile on service utilization (β=−0.595, p<0.01; β=−0.286, p<0.01, respectively). Conclusions In this study, we found that (1) service accessibility has a moderating effect on the relationship between population size and service utilization, and (2) educational profile has moderating effects on both the relationship between population size and service utilization, and the relationship between age profile and service utilization. Our findings suggest that reducing regional disparities in healthcare service utilization should take into account the interaction of geodemographic factors such as service accessibility and education. In addition, the allocation of resources for a particular healthcare service in one area should consider the geographic distribution of the same services in neighboring areas, as patients may be willing to utilize these services in areas not far from where they reside.

2016-11-08
In this report, we summarize available research in order to characterize expected rates of particle incidence on the SENSER/RROE optical instrument. We first investigate the “normal” background levels using data from statistical studies of spacecraft in geosynchronous orbit and empirical models. We then consider “worst case” scenarios based on event studies in which extreme fluxes have been observed. We use these data to define “maximum” rates of particle incidence. We then consider how incident particles will actually produce counts in the instrument by considering the effects of screening by the instrument housing and the possibility of direct particle access tomore » the housing, with rates for both primary access and secondary electron generation.« less

Efficient Unsteady Flow Visualization with High-Order Access Dependencies
DOE Office of Scientific and Technical Information (OSTI.GOV)
Zhang, Jiang; Guo, Hanqi; Yuan, Xiaoru
We present a novel high-order access dependencies based model for efficient pathline computation in unsteady flow visualization. By taking longer access sequences into account to model more sophisticated data access patterns in particle tracing, our method greatly improves the accuracy and reliability in data access prediction. In our work, high-order access dependencies are calculated by tracing uniformly-seeded pathlines in both forward and backward directions in a preprocessing stage. The effectiveness of our proposed approach is demonstrated through a parallel particle tracing framework with high-order data prefetching. Results show that our method achieves higher data locality and hence improves the efficiencymore » of pathline computation.« less

Assess whether alcohol companies restrict youth/adolescent access, interaction, and exposure to their marketing on Twitter and Instagram. Employed five fictitious male and female Twitter (n = 10) and Instagram (n = 10) user profiles aged 13, 15, 17, 19 and/or 21. Using cellular smartphones, we determined whether profiles could (a) interact with advertising content-e.g. retweet, view video or picture content, comment, share URL; and/or (b) follow and directly receive advertising material updates from the official Instagram and Twitter pages of 22 alcohol brands for 30 days. All user profiles could fully access, view, and interact with alcohol industry content posted on Instagram and Twitter. Twitter's age-gate, which restricts access for those under 21, successfully prevented underage profiles from following and subsequently receiving promotional material/updates. The two 21+ profiles collectively received 1836 alcohol-related tweets within 30 days. All Instagram profiles, however, were able to follow all alcohol brand pages and received an average of 362 advertisements within 30 days. The quantity of promotional updates increased throughout the week, reaching their peak on Thursday and Friday. Representatives/controllers of alcohol brand Instagram pages would respond directly to our underage user's comments. The alcohol industry is in violation of their proposed self-regulation guidelines for digital marketing communications on Instagram. While Twitter's age-gate effectively blocked direct to phone updates, unhindered access to post was possible. Everyday our fictitious profiles, even those as young as 13, were bombarded with alcohol industry messages and promotional material directly to their smartphones. © The Author 2015.

To explore patient preference for vascular access site in percutaneous coronary procedures, the perceived importance of benefits and risks of transradial access (TRA) and transfemoral access (TFA) were assessed. In addition, direct preference for vascular access and preference for shared decision making (SDM) were evaluated. TRA has gained significant ground on TFA during the last decades. Surveys on patient preference have mostly been performed in dedicated TRA trials. In the PREVAS study (Clinicaltrials.gov: NCT02625493) a stated preference elicitation method best-worst scaling (BWS) was used to determine patient preference for six treatment attributes: bleeding, switch of access-site, postprocedural vessel quality, mobilization and comfort, and over-night stay. Based on software-generated treatment scenarios, 142 patients indicated which characteristics they perceived most and least important in treatment choice. Best-minus-Worst scores and attribute importance were calculated. Bleeding risk was considered most important (attribute importance 31.3%), followed by length of hospitalization (22.6%), and mobilization(20.2%). Most patients preferred the approach of their current procedure (85.9%); however, 71.1% of patients with experience with both access routes favored TRA (P < 0.001). Most patients (38.0%) appreciated SDM, balanced between patient and cardiologist. Patients appreciate lower bleeding risk and early ambulation, factors favoring TRA. Previous experience with a single access route has a major impact on preference, while experience with both routes generally resulted in preference for TRA. Most patients prefer balanced SDM. © 2017 The Authors Catheterization and Cardiovascular Interventions Published by Wiley Periodicals, Inc. © 2017 The Authors Catheterization and Cardiovascular Interventions Published by Wiley Periodicals, Inc.

Increasing access to healthful foods: a qualitative study with residents of low-income communities
2015-01-01
Background Inadequate access to healthful foods has been identified as a significant barrier to healthful dietary behaviors among individuals who live in low-income communities. The purpose of this study was to gather low-income community members’ opinions about their food purchasing choices and their perceptions of the most effective ways to increase access to healthful foods in their communities. Methods Spanish and English focus groups were conducted in low-income, ethnically-diverse communities. Participants were asked about their knowledge, factors influencing their food purchasing decisions, and their perceptions regarding solutions to increase access to healthful foods. Results A total of 148 people participated in 13 focus groups. The majority of participants were female and ethnically diverse (63% Hispanic, 17% African American, 16% Caucasian, and 4% “other”). More than 75% of the participants reported making less than $1999 USD per month. Participants reported high levels of knowledge and preference for healthful foods. The most important barriers influencing healthful shopping behaviors included high price of healthful food, inadequate geographical access to healthful food, poor quality of available healthful food, and lack of overall quality of the proximate retail stores. Suggested solutions to inadequate access included placement of new chain supermarkets in their communities. Strategies implemented in convenience stores were not seen as effective. Farmers’ markets, with specific stipulations, and community gardens were regarded as beneficial supplementary solutions. Conclusion The results from the focus groups provide important input from a needs assessment perspective from the community, identify gaps in access, and offer potential effective solutions to provide direction for the future.

Recent study, but not retrieval, of knowledge protects against learning errors.
Mullet, Hillary G; Umanath, Sharda; Marsh, Elizabeth J
2014-11-01
Surprisingly, people incorporate errors into their knowledge bases even when they have the correct knowledge stored in memory (e.g., Fazio, Barber, Rajaram, Ornstein, & Marsh, 2013). We examined whether heightening the accessibility of correct knowledge would protect people from later reproducing misleading information that they encountered in fictional stories. In Experiment 1, participants studied a series of target general knowledge questions and their correct answers either a few minutes (high accessibility of knowledge) or 1 week (low accessibility of knowledge) before exposure to misleading story references. In Experiments 2a and 2b, participants instead retrieved the answers to the target general knowledge questions either a few minutes or 1 week before the rest of the experiment. Reading the relevant knowledge directly before the story-reading phase protected against reproduction of the misleading story answers on a later general knowledge test, but retrieving that same correct information did not. Retrieving stored knowledge from memory might actually enhance the encoding of relevant misinformation.

Working memory capacity and controlled serial memory search.
Mızrak, Eda; Öztekin, Ilke
2016-08-01
The speed-accuracy trade-off (SAT) procedure was used to investigate the relationship between working memory capacity (WMC) and the dynamics of temporal order memory retrieval. High- and low-span participants (HSs, LSs) studied sequentially presented five-item lists, followed by two probes from the study list. Participants indicated the more recent probe. Overall, accuracy was higher for HSs compared to LSs. Crucially, in contrast to previous investigations that observed no impact of WMC on speed of access to item information in memory (e.g., Öztekin & McElree, 2010), recovery of temporal order memory was slower for LSs. While accessing an item's representation in memory can be direct, recovery of relational information such as temporal order information requires a more controlled serial memory search. Collectively, these data indicate that WMC effects are particularly prominent during high demands of cognitive control, such as serial search operations necessary to access temporal order information from memory.

Exploring visitor acceptability for hardening trails to sustain visitation and minimize impacts
Cahill, K.L.; Marion, J.L.; Lawson, S.R.
2008-01-01
Protected natural area managers are challenged to provide high quality recreation opportunities and ensure the protection of resources from impacts associated with visitation. Development of visitor use facilities and application of site hardening practices are commonly applied tools for achieving these competing management objectives. This study applies stated choice analysis to examine visitor opinions on acceptability when they are asked to make tradeoffs among competing social, resource and management attributes in backcountry and frontcountry settings of Acadia National Park. This study demonstrates that asking visitors about recreation setting attributes uni-dimensionally, a common approach, can yield less informative responses. Analyses that considered direct tradeoffs revealed more divergent opinions on acceptability for setting attributes than a unidimensional approach. Findings revealed that visitors to an accessible and popular attraction feature supported trail development options to protect resource conditions with unrestricted visitor access. In contrast, visitors to a remote undeveloped island expressed stronger support for no or limited trail development and access restrictions to protect resource conditions.

The California Department of Transportation is studying ways to increase the use of the urban freeway systems that will accommodate the maximum number of people with the least delay and the maximum possible safety in a cost-effective way. This paper describes operational features of four different projects under way, namely: a contraflow bus lane; a part-time bus lane in the same direction and unseparated from normal traffic; a bus-carpool lane also in the same direction and unseparated from normal traffic; and a preferential access to a metered freeway.

High-efficiency particulate air (HEPA) filters do not completely prevent nosocomial fungal infections. The first aim of this study was to evaluate the impact of different filters and access conditions upon airborne fungi in hospital facilities. Additionally, this study identified fungal indicators of indoor air concentrations. Eighteen rooms and wards equipped with different air filter systems, and access conditions were sampled weekly, during 16 weeks. Tap water samples were simultaneously collected. The overall mean concentration of atmospheric fungi for all wards was 100 colony forming units/m(3). We found a direct proportionality between the levels of the different fungi in the studied atmospheres. Wards with HEPA filters at positive air flow yielded lower fungal levels. Also, the existence of an anteroom and the use of protective clothes were associated to the lowest fungal levels. Principal component analysis showed that penicillia afforded the best separation between wards' air fungal levels. Fungal strains were rarely recovered from tap water samples. In addition to air filtration systems, some access conditions to hospital units, like presence of anteroom and use of protective clothes, may prevent high fungal air load. Penicillia can be used as a general indicator of indoor air fungal levels at Hospital S. João.

The purpose of this study was to evaluate healthcare utilization and referral patterns for pain management services in a racially and ethnically diverse population. A study-specific mail survey was directed at African- (N=324) and Caucasian Americans (N=300) receiving chronic pain treatment at a tertiary care pain center to address their healthcare access, referral, and utilization patterns. Overall, 46% (N=286) responded, with the majority of respondents being Caucasian Americans (57%) and women (68%). The majority (58%) reported asking their physicians to refer them to a pain physician. African Americans were more likely to report that chronic pain was a major reason for financial problems. They made significantly more visits to the emergency room for pain care. African Americans agreed more that ethnicity and culture affected access to healthcare and pain management. They also tended to agree more than Caucasian Americans that pain medication could not control pain. These results demonstrate significant differences in healthcare utilization, access, and attitudes amongst African- and Caucasian Americans receiving chronic pain management. In light of the socioeconomic and health consequences of chronic pain, these results suggest the need for further studies addressing variability in pain care access and utilization in diverse populations.

Objective We examined whether individual-level social capital--the intangible resources in a community available through membership in social networks or other social structures and perceived trust in the community—was associated with acculturation; depression and anxiety symptoms; and perceived access to services among women of Mexican ancestry. Method Recruited through venue-based targeted sampling in King County, WA, 205 women of Mexican descent age 18 to 64 years who differed in socioeconomic status and nativity completed a cross-sectional survey. Half completed the survey in Spanish and half in English. Structural equation modeling was used for model testing. Results Social capital increased with level of acculturation and was negatively related to depression and anxiety; it had no direct association with perceived access to services. Social capital mediated the relation between acculturation and both depression and anxiety symptoms. Acculturation had no direct association with psychological distress but was directly associated with perceived access to services. This community sample of women reported high levels of psychological distress, with 20–26% of women meeting diagnostic criteria for depression or anxiety. Conclusions Social capital can be assessed at the individual level, increases with acculturation, and may be a potential target for interventions to improve mental health among Mexican American women residing in the U.S. PMID:22329824

A random access memory addressing system utilizing optical links between memory and the read/write logic circuits comprises addressing circuits including a plurality of light signal sources, a plurality of optical gates including optical detectors associated with the memory cells, and a holographic optical element adapted to reflect and direct the light signals to the desired memory cell locations. More particularly, it is a multi-port, binary computer memory for interfacing with a plurality of computers. There are a plurality of storage cells for containing bits of binary information, the storage cells being disposed at the intersections of a plurality of row conductors and a plurality of column conductors. There is interfacing logic for receiving information from the computers directing access to ones of the storage cells. There are first light sources associated with the interfacing logic for transmitting a first light beam with the access information modulated thereon. First light detectors are associated with the storage cells for receiving the first light beam, for generating an electrical signal containing the access information, and for conducting the electrical signal to the one of the storage cells to which it is directed. There are holographic optical elements for reflecting the first light beam from the first light sources to the first light detectors.

The ethical aspects of the distribution of resources for health care at the macro level deserve more study than they hitherto received. The socio-medical and economic policy implications of four distribution principles are reviewed: the utilitarian, the egalitarian, the equal access and the libertarian. Policy in welfare states is primarily based on the equal access principle. Economic factors have led to policy proposals in libertarian and utilitarian directions; competition, cost-sharing, cost-effectiveness and individual responsibility are central to the discussion. The authors conclude that it remains to be seen whether these alternatives produce the results expected. They recommend more comprehensive examination of the practical and political feasibilities of a more egalitarian policy.

In 1994 NASA Administrator selected the first high-energy particle physics experiment for the Space Station, the Alpha Magnetic Spectrometer (AMS), to place a magnetic spectrometer in Earth orbit and search for cosmic antimatter. A natural consequence of this decision was that NASA would begin to explore cost-effective ways through which the design and implementation of AMS might benefit other promising payload experiments. The first such experiment to come forward was Advanced Cosmic-Ray Composition Experiment for Space Station (ACCESS) in 1996. It was proposed as a new mission concept in space physics to attach a cosmic-ray experiment of weight, volume, and geometry similar to the AMS on the International Space Station (ISS), and replace the latter as its successor when the AMS is returned to Earth. This was to be an extension of NASA's suborbital balloon program, with balloon payloads serving as the precursor flights and heritage for ACCESS. The balloon programs have always been a cost-effective NASA resource since the particle physics instrumentation for balloon and space applications are directly related. The next step was to expand the process, pooling together expertise from various NASA centers and universities while opening up definition of the ACCESS science goals to the international community through the standard practice of peer review. This process is still ongoing, and the accommodation study presented here will discuss the baseline definition of ACCESS as we understand it today.

This study focuses on access to prenatal care and quality of care in the Family Health Strategy in Brazil as a whole and in the North region, through evaluation of infrastructure characteristics in the health units, management, and supply of care provided by the teams, from the perspective of regional and state inequalities. A cross-sectional evaluative and normative study was performed, drawing on the external evaluation component of the second round of the Program for Improvement of Access and Quality of Primary Care, in 2013-2014. The results revealed the inadequacy of the primary healthcare network's infrastructure for prenatal care, low adequacy of clinical actions for quality of care, and the teams' low management capacity to guarantee access and quality of care. In the distribution according to geopolitical regions, the findings pertaining to the units' infrastructure indicate a direct relationship between the infrastructure's adequacy and social contexts with higher municipal human development indices and income. For the clinical actions in patient care, the teams in all the regions scored low on adequacy, with slightly better results in the North and South regions of the country. There were important differences between the states of the North, and the states with higher mean income and human development scored higher on adequacy. The results indicate important organizational difficulties in both access and quality of care provided by the health teams, in addition to visible insufficiency in management activities aimed to improve access and quality of prenatal care.

Biological grafts are rarely used for the creation of vascular access, despite their many advantages. Our group prefers to use distal vascular accesses with interposition of a biological graft when direct access cannot be achieved. The objective of this study was to determine the long-term patency and the complication rate of a series of 309 vascular access procedures using a preserved saphenous (PS) vein homograft. 410 (27%) of the 1,500 vascular access procedures performed by our group required the use of a graft, including 376 PS vein homografts (25%). This retrospective study comprised complete data collection for 309 arteriovenous fistulas (AVF) using preserved saphenous (PS) vein graft in the forearm performed in 267 patients between 1985 and 2000. Primary patency was defined as the interval between creation of the vascular access and the first complication requiring surgical or radiological correction; secondary patency was defined as the interval between creation and loss of the graft, with or without revision of the fistula. Survival rates were calculated according to the Kaplan-Meier method. Inter-group comparison was performed by the Logrank test and analysis of variance was performed by logistic regression. Primary patency rates were 77%, 40% and 27% at 1,2 and 5 years, respectively. Secondary patency rates were 79% and 47% at 1 year and 5 years, respectively. The thrombosis rate was 42%. Two episodes of thrombosis occurred in 25% of grafts and 3 episodes were observed in 10% of cases. Infection rates were 1.9% postoperatively and 5% after dialysis, respectively. An aneurysm occurred on 10% of grafts. The operator's experience (RR = 1.58; p < 0.05) and diabetic nephropathy (RR = 1.89; p = 0.059) significantly influenced graft patency. In contrast, the position of the graft, the fact that it crossed the elbow joint, and the site of the arterial anastomosis did not have any negative impact on graft patency. Preservation of the patient's vascular capital is an essential objective in patients with chronic renal insufficiency, which is sometimes difficult to reconcile with the need to create vascular accesses with a long life span. The strategic choice between a distal access requiring a graft and a direct proximal access depends on the clinical context: cardiac function, waiting list for renal transplantation. Our preferred material in the case of bypass graft is the PS graft, as it presents the same resistance and the same patency rates as synthetic grafts, without the associated septic complications. The PS vein graft is a good material for the creation of vascular accesses with similar patency rates to those of prosthetic grafts. Vein grafts present a number of advantages, particularly a greater ease of use facilitating distal implantation of the graft and a low infection rate.

Open-access and multi-directional electroosmotic flow chip for positioning heterotypic cells.
Terao, Kyohei; Kitazawa, Yuko; Yokokawa, Ryuji; Okonogi, Atsuhito; Kotera, Hidetoshi
2011-04-21
We propose a novel method of cell positioning using electroosmotic flow (EOF) to analyze cell-cell interactions. The EOF chip has an open-to-air configuration, is equipped with four electrodes to induce multi-directional EOF, and allows access of tools for liquid handling and of physical probes for cell measurements. Evaluation of the flow within this chip indicated that it controlled hydrodynamic transport of cells, in terms of both speed and direction. We also evaluated cell viability after EOF application and determined appropriate conditions for cell positioning. Two cells were successively positioned in pocket-like microstructures, one in each micropocket, by controlling the EOF direction. As an experimental demonstration, we observed contact interactions between two individual cells through gap junction channels. The EOF chip should provide ways to elucidate various cell-cell interactions between heterotypic cells.

A Hybrid Lifetime Extended Directional Approach for WBANs
Li, Changle; Yuan, Xiaoming; Yang, Li; Song, Yueyang
2015-01-01
Wireless Body Area Networks (WBANs) can provide real-time and reliable health monitoring, attributing to the human-centered and sensor interoperability properties. WBANs have become a key component of the ubiquitous eHealth (electronic health) revolution that prospers on the basis of information and communication technologies. The prime consideration in WBAN is how to maximize the network lifetime with battery-powered sensor nodes in energy constraint. Novel solutions in Medium Access Control (MAC) protocols are imperative to satisfy the particular BAN scenario and the need of excellent energy efficiency in healthcare applications. In this paper, we propose a hybrid Lifetime Extended Directional Approach (LEDA) MAC protocol based on IEEE 802.15.6 to reduce energy consumption and prolong network lifetime. The LEDA MAC protocol takes full advantages of directional superiority in energy saving that employs multi-beam directional mode in Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) and single-beam directional mode in Time Division Multiple Access (TDMA) for alternative in data reservation and transmission according to the traffic varieties. Moreover, the impacts of some inherent problems of directional antennas such as deafness and hidden terminal problem can be decreased owing to that all nodes generate individual beam according to user priorities designated. Furthermore, LEDA MAC employs a Dynamic Polled Allocation Period (DPAP) for burst data transmissions to increase the network reliability and adaptability. Extensive analysis and simulation results show that the proposed LEDA MAC protocol achieves extended network lifetime with improved performance compared with IEEE 802.15.6. PMID:26556357

A classical but still open issue in cognitive psychology concerns the depth of subliminal processing. Can the meaning of undetected words be accessed in the absence of consciousness? Subliminal priming experiments in normal subjects have revealed only small effects whose interpretation remains controversial. Here, we provide a direct demonstration of semantic access for unseen masked words. In three epileptic patients with intracranial electrodes, we recorded brain potentials from the amygdala, a neural structure that responds to fearful or threatening stimuli presented in various modalities, including written words. We show that the subliminal presentation of emotional words modulates the activity of the amygdala at a long latency (>800 ms). Our result indicates that subliminal words can trigger long-lasting cerebral processes, including semantic access to emotional valence.

A Review on Spectral Amplitude Coding Optical Code Division Multiple Access
NASA Astrophysics Data System (ADS)
Kaur, Navpreet; Goyal, Rakesh; Rani, Monika
2017-06-01
This manuscript deals with analysis of Spectral Amplitude Coding Optical Code Division Multiple Access (SACOCDMA) system. The major noise source in optical CDMA is co-channel interference from other users known as multiple access interference (MAI). The system performance in terms of bit error rate (BER) degrades as a result of increased MAI. It is perceived that number of users and type of codes used for optical system directly decide the performance of system. MAI can be restricted by efficient designing of optical codes and implementing them with unique architecture to accommodate more number of users. Hence, it is a necessity to design a technique like spectral direct detection (SDD) technique with modified double weight code, which can provide better cardinality and good correlation property.

EntrezAJAX: direct web browser access to the Entrez Programming Utilities.
Loman, Nicholas J; Pallen, Mark J
2010-06-21
Web applications for biology and medicine often need to integrate data from Entrez services provided by the National Center for Biotechnology Information. However, direct access to Entrez from a web browser is not possible due to 'same-origin' security restrictions. The use of "Asynchronous JavaScript and XML" (AJAX) to create rich, interactive web applications is now commonplace. The ability to access Entrez via AJAX would be advantageous in the creation of integrated biomedical web resources. We describe EntrezAJAX, which provides access to Entrez eUtils and is able to circumvent same-origin browser restrictions. EntrezAJAX is easily implemented by JavaScript developers and provides identical functionality as Entrez eUtils as well as enhanced functionality to ease development. We provide easy-to-understand developer examples written in JavaScript to illustrate potential uses of this service. For the purposes of speed, reliability and scalability, EntrezAJAX has been deployed on Google App Engine, a freely available cloud service. The EntrezAJAX webpage is located at http://entrezajax.appspot.com/

Healthcare providers (HCPs) use online medical information for self-directed learning and patient care. Recently, the mobile internet has emerged as a new platform for accessing medical information as it allows mobile devices to access online information in a manner compatible with their restricted storage. We investigated mobile internet usage parameters to direct the future development of mobile internet teaching websites. Nephrology On-Demand Mobile (NODM) (http://www.nephrologyondemand.org) was made accessible to all mobile devices. From February 1 to December 31, 2010, HCP use of NODM was tracked using code inserted into the root files. Nephrology On-Demand received 15 258 visits, of which approximately 10% were made to NODM, with the majority coming from the USA. Most access to NODM was through the Apple iOS family of devices and cellular connections were the most frequently used. These findings provide a basis for the future development of mobile nephrology and medical teaching tools. PMID:21659443

In this study, total ten Miscanthus accessions exhibited diverse cell wall compositions, leading to largely varied hexoses yields at 17%-40% (% cellulose) released from direct enzymatic hydrolysis of steam-exploded (SE) residues. Further supplied with 2% Tween-80 into the enzymatic digestion, the Mis7 accession showed the higher hexose yield by 14.8-fold than that of raw material, whereas the Mis10 had the highest hexoses yield at 77% among ten Miscanthus accessions. Significantly, this study identified four wall polymer features that negatively affect biomass saccharification as p<0.05 or 0.01 in the SE residues, including cellulose DP, Xyl and Ara of hemicellulose, and S-monomer of lignin. Based on Simons' stain, the SE porosity (defined by DY/DB) was examined to be the unique positive factor on biomass enzymatic digestion. Hence, this study provides the potential strategy to enhance biomass saccharification using optimal biomass process technology and related genetic breeding in Miscanthus and beyond.

It is not known whether ongoing access to a broad-based Internet knowledge resource can influence the practice of health care providers. We undertook a study to evaluate the impact of a Web-based knowledge resource on increasing access to evidence and facilitating best practice of health care providers. The objective of this study was to evaluate (1) the impact of the Spinal Cord Injury Rehabilitation Evidence (SCIRE) project on access to information for health care providers and researchers and (2) how SCIRE influenced health care providers' management of clients. A 4-part mixed methods evaluation was undertaken: (1) monitoring website traffic and utilization using Google Analytics, (2) online survey of users who accessed the SCIRE website, (3) online survey of targeted end-users, that is, rehabilitation health care providers known to work with spinal cord injury (SCI) clients, as well as researchers, and (4) focus groups with health care providers who had previously accessed SCIRE. The online format allowed the content for a relatively specialized field to have far reach (eg, 26 countries and over 6500 users per month). The website survey and targeted end-user survey confirmed that health care providers, as well as researchers perceived that the website increased their access to SCI evidence. Access to SCIRE not only improved knowledge of SCI evidence but helped inform changes to the health providers' clinical practice and improved their confidence in treating SCI clients. The SCIRE information directly influenced the health providers' clinical decision making, in terms of choice of intervention, equipment needs, or assessment tool. A Web-based knowledge resource may be a relatively inexpensive method to increase access to evidence-based information, increase knowledge of the evidence, inform changes to the health providers' practice, and influence their clinical decision making.

Mind the gap: An empirical study of post-trial access in HIV biomedical prevention trials.
Haire, Bridget; Jordens, Christopher
2015-08-01
The principle of providing post-trial access for research participants to successful products of that research is widely accepted and has been enshrined in various declarations and guidelines. While recent ethical guidelines recognise that the responsibility to provide post-trial access extends to sponsors, regulators and government bodies as well as to researchers, it is the researchers who have the direct duty of care to participants. Researchers may thus need to act as advocates for trial participants, especially where government bodies, sponsors, and regulatory bodies have complex interests vested in decisions about whether or not new interventions are made available, how, and to whom. This paper provides an empirical account of post-trial access in the context of HIV prevention research. It describes both access to the successful products of research and the provision antiretroviral drugs for trial participants who acquire HIV. First, we provide evidence that, in the current system, there is considerable variation in the duration and timeliness of access. We then argue that by analysing the difficulties faced by researchers to this point, and their efforts to meet this obligation, much can be learned about how to secure post-trial access in HIV biomedical preventions trials. While researchers alone have a limited obligation, their advocacy on behalf of trial participants may be necessary to call the other parties to account. © 2013 John Wiley & Sons Ltd.

Direct prediction of the three-dimensional (3D) structures of proteins from one-dimensional (1D) sequences is a challenging problem. Significant structural characteristics such as solvent accessibility and contact number are essential for deriving restrains in modeling protein folding and protein 3D structure. Thus, accurately predicting these features is a critical step for 3D protein structure building. In this study, we present DeepSacon, a computational method that can effectively predict protein solvent accessibility and contact number by using a deep neural network, which is built based on stacked autoencoder and a dropout method. The results demonstrate that our proposed DeepSacon achieves a significant improvement in the prediction quality compared with the state-of-the-art methods. We obtain 0.70 three-state accuracy for solvent accessibility, 0.33 15-state accuracy and 0.74 Pearson Correlation Coefficient (PCC) for the contact number on the 5729 monomeric soluble globular protein dataset. We also evaluate the performance on the CASP11 benchmark dataset, DeepSacon achieves 0.68 three-state accuracy and 0.69 PCC for solvent accessibility and contact number, respectively. We have shown that DeepSacon can reliably predict solvent accessibility and contact number with stacked sparse autoencoder and a dropout approach.

Computerized clinical documentation system in the pediatric intensive care unit
2001-01-01
Background To determine whether a computerized clinical documentation system (CDS): 1) decreased time spent charting and increased time spent in patient care; 2) decreased medication errors; 3) improved clinical decision making; 4) improved quality of documentation; and/or 5) improved shift to shift nursing continuity. Methods Before and after implementation of CDS, a time study involving nursing care, medication delivery, and normalization of serum calcium and potassium values was performed. In addition, an evaluation of completeness of documentation and a clinician survey of shift to shift reporting were also completed. This was a modified one group, pretest-posttest design. Results With the CDS there was: improved legibility and completeness of documentation, data with better accessibility and accuracy, no change in time spent in direct patient care or charting by nursing staff. Incidental observations from the study included improved management functions of our nurse manager; improved JCAHO documentation compliance; timely access to clinical data (labs, vitals, etc); a decrease in time and resource use for audits; improved reimbursement because of the ability to reconstruct lost charts; limited human data entry by automatic data logging; eliminated costs of printing forms. CDS cost was reasonable. Conclusions When compared to a paper chart, the CDS provided a more legible, compete, and accessible patient record without affecting time spent in direct patient care. The availability of the CDS improved shift to shift reporting. Other observations showed that the CDS improved management capabilities; helped physicians deliver care; improved reimbursement; limited data entry errors; and reduced costs. PMID:11604105

The aim of this prospective quantitative study was to compare the effect of different instructional formats on dental students' skills and knowledge acquisition for access cavity preparation. All first-year dental students were invited to participate in this study conducted during the four consecutive two-week endodontic rotation courses at the University of the Pacific Arthur A. Dugoni School of Dentistry in spring semester 2015. Four alphabetically distributed intact groups of students were randomly allocated to two groups (n=70 each) that participated in either small-group discussion or a traditional lecture on access preparation. The first outcome measure was skill acquisition, measured by the quality of access cavities prepared in extracted teeth at the conclusion of the session. Two blinded raters scored direct observations on a continuous scale. Knowledge, the second outcome measure, was scored with a multiple-choice and open-ended question test at the end of each two-week session. Data were obtained for 134 of the 140 students, for a 96% response rate. The results showed that students in the small-group discussion groups scored significantly higher than those in the lecture groups when skill performance was tested (p=8.9 × 10(-7)). However, no significant differences were found in the acquisition of knowledge between the two groups on the written test. Active student participation was significantly related to improved manual skill acquisition, but the format of the session does not seem to have had a direct influence on acquired knowledge.

Physiotherapy phone based, "Physio Direct" (PD) musculoskeletal triage and treat services are a relatively new phenomena. This study explored Physiotherapist and GP attitudes towards PD services. Online national survey via cascade e-mail initiated by study leads. 488 Physiotherapists and 68 GPs completed the survey. The survey asked three negatively worded and three positively worded Likert scale questions regarding PD services. It also collected demographic data and more global attitudes including a version of the friends and family test. Overall both Physiotherapists and GP's have positive attitudes towards PD services. There was global agreement that PD triage was a good idea but in both groups the majority of respondents who expressed a definite opinion thought that patients would still eventually need to be seen face to face. The vast majority of all respondents also thought patients should be given a choice about first accessing PD services. Physiotherapists with experience of PD services had more positive and less negative attitudes than those without experience. More detailed results are discussed. Relevant clinical stakeholders have generally positive attitudes towards PD services, but more so when they have experience of them. Counter to research findings significant proportions of respondents believe patients accessing PD services will still need to be seen face to face. The significant majority of respondents believe patients should be given a choice whether they access PD services in the first instance or not. Copyright © 2016 Chartered Society of Physiotherapy.

Precise definition of anonymization in genetic polymorphism studies.
Hamajima, Nobuyuki; Atsuta, Yoshiko; Niwa, Yoshimitsu; Nishio, Kazuko; Tanaka, Daisuke; Yamamoto, Kazuhito; Tamakoshi, Akiko
2004-01-01
Anonymization is an essential tool to protect privacy of participants in epidemiological studies. This paper classifies types of anonymization in genetic polymorphism studies, providing precise definitions. They are: 1) unlinkable anonymization at enrollment without a participant list; 2) unlinkable anonymization before genotyping with a participant list; 3) linkable anonymization; 4) unlinkable anonymization for outsiders; and 5) linkable anonymization for outsiders. The classification in view of accessibility to a table including genotype data with directly identifiable data such as names is important; if such tables exist, staff may obtain genotype information about participants. The first three modes are defined here as anonymization unaccessible to genotype data with directly identifiable information for research staff. Anonymization with a key code held by participants is possible with any of the above anonymization modes, by which participants can access to their own genotypes through telephone or internet. A guideline issued on March 29, 2001 with collaboration of three Ministries in Japan defines "anonymization in a linkable fashion" and "anonymization in an unlinkable fashion", "for the purpose of preventing the personal information from being divulged externally in violation of law, the present guidelines or a research protocol", but the contents are not clear in practice. The proposed definitions will be useful when we describe and discuss the preferable mode of anonymization for a given polymorphism study.

This study investigated the use of direct visualization to enhance minimally invasive epicardial procedures. A commercially available miniature camera was placed in a prototype subxiphoid introducer needle and bench top, in vitro and in vivo tests of system performance were made during simulated and actual attempts at pericardial access and cardio-endoscopy. This system had an unshielded field of view of 100° and a resolution of 220 × 224 pixels. When a sleeve used to maintain depth of field was slid past the distal tip of the camera probe, the field of view would decrease by ≈15° per millimetre of sleeve extension, but without loss of image quality. While tests during in vivo subxiphoid access in a porcine model revealed that the pericardial membrane was difficult to localize, the results also showed excellent resolution of the coronary arteries on the epicardial surface. These findings and potential improvements are discussed in detail.

Perceived Ease of Access to Alcohol, Tobacco, and Other Substances in Rural and Urban US Students
Warren, Jacob C.; Smalley, K. Bryant; Barefoot, K. Nikki
2015-01-01
Introduction Ease of access to substances has been shown to have a direct and significant relationship with substance use for school-aged children. Previous research involving rural samples of middle and high school students reveals that perceived ease of access to substances is a significant predictor of recent use among rural adolescents; however, it is unclear if perceived access to substances varies between rural and urban areas. The purpose of the current study was to examine rural-urban differences in perceived ease of access to alcohol, smoking and chewing tobacco, marijuana, and seven other substances in order to better inform and promote future substance use prevention and programming efforts in rural areas. Methods Data were analyzed from the 2013 Georgia Student Health Survey II, administered in all public and interested private/charter schools in the state of Georgia. A total of 513,909 students (18.2% rural) indicated their perceived ease of access to 11 substances on a 4-point Likert-type scale. Rural-urban differences were investigated using chi-square analysis. Results In general, it appeared the rural-urban differences fell along legal/illicit lines. For middle school students, a significant difference in perceived ease of access was found for each substance, with rural students reporting greater access to smoking tobacco, chewing tobacco, and steroids, and urban students reporting greater access to alcohol, marijuana, cocaine, inhalants, ecstasy, methamphetamine, hallucinogens, and prescription drugs. Rural high school students reported higher access to alcohol, smoking tobacco, chewing tobacco, and steroids, with urban students reporting higher access to marijuana, cocaine, inhalants, ecstasy, and hallucinogens. Perceptions of ease of access more than doubled for each substance in both geographies between middle and high school. Conclusions In summary, the current study found multiple and fairly consistent differences between rural and urban students’ perceived ease of access to a variety of substances, with rural students reporting higher levels of access to legal substances and urban students reporting higher levels of access predominantly to illicit substances. Most troubling were the high levels of perceived access to substances, however, particularly in high school students, with more than half even of rural students reporting at least somewhat easy access to marijuana, and more than 60% of both rural and urban high school students reporting easy access to alcohol. Future research should investigate ways to decrease the perceptions of access to substances in order to prevent use and abuse. PMID:26518286

Low mood is a common mental health problem with significant health consequences. Studies have shown that cognitive behavioural therapy (CBT) is an effective treatment for low mood and anxiety when delivered one-to-one by an expert practitioner. However, access to this talking therapy is often limited and waiting lists can be long, although a range of low-intensity interventions that can increase access to services are available. These include guided self-help materials delivered via books, classes and online packages. This project aims to pilot a randomized controlled trial of an online CBT-based life skills course with community-based individuals experiencing low mood and anxiety. Individuals with elevated symptoms of depression will be recruited directly from the community via online and newspaper advertisements. Participants will be remotely randomized to receive either immediate access or delayed access to the Living Life to the Full guided online CBT-based life skills package, with telephone or email support provided whilst they use the online intervention. The primary end point will be at 3 months post-randomization, at which point the delayed-access group will be offered the intervention. Levels of depression, anxiety, social functioning and satisfaction will be assessed. This pilot study will test the trial design, and ability to recruit and deliver the intervention. Drop-out rates will be assessed and the completion and acceptability of the package will be investigated. The study will also inform a sample size power calculation for a subsequent substantive randomized controlled trial. ISRCTN ISRCTN12890709.

This paper presents an energy-efficient Medium Access Control (MAC) protocol for very-high-throughput millimeter-wave (mm-wave) wireless sensor communication networks (VHT-MSCNs) based on hybrid multiple access techniques of frequency division multiplexing access (FDMA) and time division multiplexing access (TDMA). An energy-efficient Superframe for wireless sensor communication network employing directional mm-wave wireless access technologies is proposed for systems that require very high throughput, such as high definition video signals, for sensing, processing, transmitting, and actuating functions. Energy consumption modeling for each network element and comparisons among various multi-access technologies in term of power and MAC layer operations are investigated for evaluating the energy-efficient improvement of proposed MAC protocol.

Socio-economic and locational determinants of accessibility and utilization of primary health-care.
Field, K S; Briggs, D J
2001-09-01
Differences in levels of utilization vary and are a function of socio-economic and geographical factors. This paper presents the results of a questionnaire study involving twelve GP practices in Northamptonshire, UK, of factors which affect access and utilization in asthmatics and diabetics; these groups were selected to control for differences in utilization behaviour, as a result of different aetiologies. The questionnaire sought data on: residential location of patients, utilization characteristics of primary health-care, personal circumstances and mobility and hindrances to access and utilization. Key themes were identified relating to age, gender, social class, employment, ethnicity and proximity to the GP surgery. The young, elderly and females report higher rates of utilization, as do nonmanual workers and those who are unemployed. However, accessibility and utilization vary greatly in response to mobility and locational characteristics; these variations tend to be masked by data on overall rates of usage. Optimal scaling techniques were used to investigate the interactions between the factors affecting accessibility and utilization, and to characterize patients in terms of their levels of utilization. Results confirmed that current service provision afforded a differential level of service to patients, which does not directly reflect their level of need.

Grangaard, Sidse; Frandsen, Anne Kathrine
2016-01-01
The research project 'An analysis of the accessibility requirements' studies how Danish architectural firms experience the accessibility requirements of the Danish Building Regulations and it examines their opinions on how future regulative models can support innovative and inclusive design - Universal Design (UD). The empirical material consists of input from six workshops to which all 700 Danish Architectural firms were invited, as well as eight group interviews. The analysis shows that the current prescriptive requirements are criticized for being too homogenous and possibilities for differentiation and zoning are required. Therefore, a majority of professionals are interested in a performance-based model because they think that such a model will support 'accessibility zoning', achieving flexibility because of different levels of accessibility in a building due to its performance. The common understanding of accessibility and UD is directly related to buildings like hospitals and care centers. When the objective is both innovative and inclusive architecture, the request of a performance-based model should be followed up by a knowledge enhancement effort in the building sector. Bloom's taxonomy of educational objectives is suggested as a tool for such a boost. The research project has been financed by the Danish Transport and Construction Agency.

Compared with plant detritus, animal detritus yields higher growth rates, survival, adult mass, and population growth of container-dwelling mosquitoes. It is unclear whether the benefit from animal detritus to larvae results from greater microorganism growth, direct ingestion of animal detritus by larvae, or some other mechanism. We tested alternative mechanisms by which animal detritus may benefit the invasive container-dwelling mosquito Aedesalbopictus (Skuse) (Diptera: Culicidae). In the laboratory, larvae were reared under three conditions with access to 1) detritus, but where microorganisms in the water column were reduced through periodic flushing; 2) water column microorganisms, but larvae had no direct access to detritus; or 3) both water column microorganisms and detritus. Access treatments were conducted for three masses of animal detritus: 0.005, 0.010, and 0.020 g. Water column bacterial productivity (measured via incorporation of [3H]leucine) decreased significantly with flushing and with larval presence. Removing microorganisms through flushing significantly reduced mass of adult mosquitoes (both sexes), and it significantly prolonged developmental times of females compared with treatments where water column microorganisms or microorganisms and detritus were available. Survival to adulthood was greatest when larvae had access to both water column microorganisms and 0.020 g of detritus, but it declined when only water column microorganisms were available or when 0.005 g of detritus was used. These findings indicate both direct (as a food source) and indirect (assisting with decomposition of detritus) roles of microorganisms in producing the benefit of animal detritus to container mosquito larvae.

Conducting Research as a Visiting Scientist in a Women’s Prison
Byrne, Mary Woods
2006-01-01
Incarcerated populations have disparities in health risks and illness conditions meriting study, but the history of prison research is marred by unethical conduct. Ethical participation strategies are discussed in the context of studies implemented by the author in a state prison system. This study used ethnographic approaches, observed adherence to federal and institutional review board regulations and corrections department directives, and maintained continuous communication with vested interests to provide entry and long-term access for studies on female prisoners and their civilian infants. A culture clash between the punitive restrictive environment that serves the custody–control–care mission of corrections systems and the open inquiry environment needed for conduct of health research exists. Federal regulations protect prisoners as human subjects but additional vigilance and communication by researchers are required. Gaining and maintaining access to prison inmates for nursing research are leadership challenges that can be met within the caring and collaborative paradigm of nursing. PMID:16061169

How was the UNAIDS drug access initiative implemented in Chile?
Brousselle, Astrid; Champagne, François
2012-01-01
In 1997, UNAIDS decided to implement Drug Access Initiatives (DAI) in four different pilot-countries. We studied the implementation of the DAI in Chile as part of the evaluation program conducted by the ‘Agence Nationale de Recherche sur le SIDA’ (ANRS/France). The objective was to understand how the politico-organizational dynamic influenced the implementation process of the DAI. Approximately 50 semi-directed interviews and observation activities were conducted with the actors who participated in the implementation of the DAI or who played a role in the HIV/AIDS context. The program theory models were established and their evolution analyzed. This article offers an original analysis of an international HIV/AIDS drug access program that was put in place at a time when such programs were seen as a priority by international and governmental institutions. It also offers some insights for the creation of international projects that will be locally implemented. PMID:23230344

This study adds to the growing body of knowledge on gender nonconformity aspects of heteronormativity by examining its impact on the life course of hijras and their access to fundamental human rights in Pakistan. Drawing on 50 semistructured interviews conducted in two sites, the findings suggest that the participants' lived experiences associated with gender nonconformity significantly influenced the direction of their life course and their ability to have access to human rights. These experiences spanned from childhood to elderhood across a wide range of settings, such as family, school, guru dera (residence headed by a hijra guru), workplace, and interactions with authorities. The participants' human rights were not recognized, resulting in abuse, social stigma, discrimination against them, and their exclusion from mainstream society. Finally, implications are drawn for public policy and future research on third gender concerns in Pakistan and elsewhere.

Superior Recess Access of the Lumbar Facet Joint.
Demir-Deviren, Sibel; Singh, Sukhminder; Hanelin, Joshua
2017-04-01
Descriptive approach to accessing the lumbar facet joint by superior recess. This study is aimed to describe an approach to accessing the lumbar facet joint through targeting the superior recess during lumbar facet joint injections. Lumbar facet joint injections are routinely performed for both the diagnosis and treatment of chronic low back pain. Previous studies either did not specify which part of the joint to target, or recommended targeting the inferior aspect of the joint to access the inferior recess. One study did mention the superior recess as an alternative to injecting the inferior recess, but none has focused on description of the technique. This is the first time this technique has been described. The records and fluoroscopic images were reviewed for all patients over a period of 9 months (January-September 2012) using the proposed technique. This resulted in a total of 48 patients; 15 men, 29 women, and a total of 117 facet joint intra-articular injections. Among these 48 patients, injections were repeated in total of 4 cases. The average time of injections among 4 repeat cases was 121 days. The success of the procedure was confirmed with an arthrogram demonstrating contrast flowing from the superior recess inferiorly through the joint space. Successful access of the lumbar facet joint through puncture of the superior recess was seen in 114 cases, with 3 unsuccessful attempts to enter facet joints due to osteophytes at involved levels. There were no complications observed during the procedure. We find this approach to be highly successful, safe, and well tolerated by the patient and recommend it as a technique for access of the lumbar facet joint in those patients in whom direct puncture of the inferior recess is difficult.

Effects of urbanization on direct and indirect interactions in a tri-trophic system.
Tabea, Turrini; Dirk, Sanders; Eva, Knop
2016-04-01
While effects of urbanization on species assemblages are receiving increasing attention, effects on ecological interactions remain largely unexplored. We investigated how urbanization influences the strength of direct and indirect trophic interactions in a tri- trophic system. In a field experiment including five cities and nearby farmed areas, we used potted Vicia faba plants and manipulated the presence of Megoura viciae aphids and that of naturally occurring aphid predators. When predators could access aphids, they reduced their abundance less in the urban than in the agricultural ecosystem. Compared to aphid abundance on plants without predator access, abundance on plants with predator access was 2.58 times lower in urban and 5.27 times lower in agricultural areas. This indicates that urbanization limited top-down control of aphids by predators. In both ecosystems, plant biomass was negatively affected by herbivores and positively affected by predators, but the positive indirect predator effect was weaker in cities. Compared to aphid-infested plants without predator access, plants with predator access were 1.89 times heavier in urban and 2.12 times heavier in agricultural areas. Surprisingly, differences between ecosystems regarding the indirect predator effect on plants were not explained by the differentially strong herbivore suppression. Instead, the urban environment limited plant biomass per se, thereby mitigating the scope of a positive predator effect. Our results show that urbanization can influence direct and indirect trophic interactions through effects on biotic top-down forces and on plant growth. In order to understand how urbanization affects biodiversity and ecosystem functioning, it is fundamental to not only consider species assemblages, but also species interactions.

Petaminer: Using ROOT for efficient data storage in MySQL database
NASA Astrophysics Data System (ADS)
Cranshaw, J.; Malon, D.; Vaniachine, A.; Fine, V.; Lauret, J.; Hamill, P.
2010-04-01
High Energy and Nuclear Physics (HENP) experiments store Petabytes of event data and Terabytes of calibration data in ROOT files. The Petaminer project is developing a custom MySQL storage engine to enable the MySQL query processor to directly access experimental data stored in ROOT files. Our project is addressing the problem of efficient navigation to PetaBytes of HENP experimental data described with event-level TAG metadata, which is required by data intensive physics communities such as the LHC and RHIC experiments. Physicists need to be able to compose a metadata query and rapidly retrieve the set of matching events, where improved efficiency will facilitate the discovery process by permitting rapid iterations of data evaluation and retrieval. Our custom MySQL storage engine enables the MySQL query processor to directly access TAG data stored in ROOT TTrees. As ROOT TTrees are column-oriented, reading them directly provides improved performance over traditional row-oriented TAG databases. Leveraging the flexible and powerful SQL query language to access data stored in ROOT TTrees, the Petaminer approach enables rich MySQL index-building capabilities for further performance optimization.

Percutaneous Portal Vein Access and Transhepatic Tract Hemostasis
Saad, Wael E. A.; Madoff, David C.
2012-01-01
Percutaneous portal vein interventions require minimally invasive access to the portal venous system. Common approaches to the portal vein include transjugular hepatic vein to portal vein access and direct transhepatic portal vein access. A major concern of the transhepatic route is the risk of postprocedural bleeding, which is increased when patients are anticoagulated or receiving pharmaceutical thrombolytic therapy. Thus percutaneous portal vein access and subsequent closure are important technical parts of percutaneous portal vein procedures. At present, various techniques have been used for either portal access or subsequent transhepatic tract closure and hemostasis. Regardless of the method used, meticulous technique is required to achieve the overall safety and effectiveness of portal venous procedures. This article reviews the various techniques of percutaneous transhepatic portal vein access and the various closure and hemostatic methods used to reduce the risk of postprocedural bleeding.

Measuring the EMS patient access time interval and the impact of responding to high-rise buildings.
Morrison, Laurie J; Angelini, Mark P; Vermeulen, Marian J; Schwartz, Brian
2005-01-01
To measure the patient access time interval and characterize its contribution to the total emergency medical services (EMS) response time interval; to compare the patient access time intervals for patients located three or more floors above ground with those less than three floors above or below ground, and specifically in the apartment subgroup; and to identify barriers that significantly impede EMS access to patients in high-rise apartments. An observational study of all patients treated by an emergency medical technician paramedics (EMT-P) crew was conducted using a trained independent observer to collect time intervals and identify potential barriers to access. Of 118 observed calls, 25 (21%) originated from patients three or more floors above ground. The overall median and 90th percentile (95% confidence interval) patient access time intervals were 1.61 (1.27, 1.91) and 3.47 (3.08, 4.05) minutes, respectively. The median interval was 2.73 (2.22, 3.03) minutes among calls from patients located three or more stories above ground compared with 1.25 (1.07, 1.55) minutes among those at lower levels. The patient access time interval represented 23.5% of the total EMS response time interval among calls originating less than three floors above or below ground and 32.2% of those located three or more stories above ground. The most frequently encountered barriers to access included security code entry requirements, lack of directional signs, and inability to fit the stretcher into the elevator. The patient access time interval is significantly long and represents a substantial component of the total EMS response time interval, especially among ambulance calls originating three or more floors above ground. A number of barriers appear to contribute to delayed paramedic access.

The nature of science and the preservice elementary teacher: Changes in understanding and practice
NASA Astrophysics Data System (ADS)
Rivas, Michael Gerald
This action research project studies preservice elementary teachers in a science methods course. The purpose of this research project was to enhance preservice teachers' understanding of specific nature of science (NOS) tenets so as to promote equity and access within the elementary science classroom. In particular, I chose five NOS tenets that were listed in the first chapter of the AAAS (1989) document titled, "The Nature of Science," and connected them to equitable educational goals and practices. The theoretical framework guiding this study came from bodies of scholarship relating to the NOS, social constructivism, and action research. This study addressed the following three questions: (1) What opportunities were provided the preservice teachers so that they could enhance their understandings of the NOS? (2) What were the changes in preservice teachers' understanding of the NOS as a result? (3) How did the prospective teachers' understandings of the NOS translate into their classroom practice? The analysis revealed that the science methods course's operational curriculum consisted of implicit and explicit teaching of the NOS, as well as intended and untended NOS tenets. The prospective teachers initially held a limited view of the NOS, but by the end of the course their view had been enhanced. In addition, the participants made direct connections between their new understandings of the NOS and equity and access in the science classroom. In their teaching, the preservice teachers as a group implicitly taught all five of the NOS tenets. In fact, a majority taught three of the five intended tenets. Explicitly, only one tenet was taught, but it was taught with a direct connection to making the science classroom more inclusive. The findings of this study indicate that preservice teachers can have their views of the NOS enhanced even though they may have experienced years of deficient science instruction. They pointed out that this enhanced view of the NOS can be translated into classroom practice. The findings also showed that a direct connection can be made between understandings of the NOS and issues of equity and access at the elementary level.

Integration of a supersonic inlet simulation with a computer aided design (CAD) system is demonstrated. The integration is performed using the Project Integration Architecture (PIA). PIA provides a common environment for wrapping many types of applications. Accessing geometry data from CAD files is accomplished by incorporating appropriate function calls from the Computational Analysis Programming Interface (CAPRI). CAPRI is a CAD vendor neutral programming interface that aids in acquiring geometry data directly from CAD files. The benefits of wrapping a supersonic inlet simulation into PIA using CAPRI are; direct access of geometry data, accurate capture of geometry data, automatic conversion of data units, CAD vendor neutral operation, and on-line interactive history capture. This paper describes the PIA and the CAPRI wrapper and details the supersonic inlet simulation demonstration.

The UN Convention on the Rights of Persons with Disabilities requires states 'to ensure to persons with disabilities access, on an equal basis with others, to the physical environment, transportation, information and communications.' We explored whether this convention was respected for disabled children in Europe. One thousand one-hundred and seventy-four children aged 8-12 years were randomly selected from population-based registers of children with cerebral palsy in eight European regions. 743 children joined the study; one further region recruited 75 children from multiple sources. Researchers visited these 818 children and administered the European Child Environment Questionnaire, which records parents' perceptions of availability of the physical, social and attitudinal environment needed in home, school and community. Multilevel, multivariable regression related child access on these domains to their impairments and socio-demographic characteristics. Children with more impaired walking ability had less access to the physical environment, transport and social support they needed than other children. They also experienced less favourable attitudes from family and friends. However, attitudes of teachers and therapists were similar for children with all levels of impairment. The access of children, across all impairment severities, to their needed environment showed significant variation between regions (p ≤ 0.0001), some regions consistently providing better access on most or all domains. European states need to substantially improve environmental access for disabled children in order to meet their obligations under UN Conventions. In some regions, many environmental factors should and realistically could be changed. Legislation and regulation should be directed to making this happen. Local environmental planners and health and social service providers should listen carefully to parents to address mismatches between policy intentions and parental experience.

Most of the physiological studies of the pigeon retino-tectal visual pathway have investigated the accessible tectum, a small dorso-lateral tectal section that can be easily accessed by a simple craniotomy. However, at present we lack a detailed study of the topographical arrangement between the visual field, the retina and the accessible tectum. In particular, it is not known which section of the visual field is mapped onto the accessible tectum, and which of the specialized retinal areas mediates this projection. Here we determined, using local field potential (LFP) recordings and reverse retinoscopy, the shape, size and position in the visual space of the portion of the visual field mapped onto the accessible tectum (called here the accessible visual field, or AVF). Using this data and the mapping of Nalbach et al. [Vis. Res. 30 (4) (1990) 529], the retinal area corresponding to the AVF was determined. Such retinal area was also directly delimited by means of retrograde transport of DiI. The results indicate that the AVF is a triangular perifoveal zone encompassing only 15% of total visual field. The retinal region corresponding to the AVF has the shape of an elongated triangle that runs parallel to the visual equator and contains the fovea, the tip of the pecten, a perifoveal region of the yellow field and a small crescent of the red field. In agreement with this anatomical heterogeneity, visual evoked potentials measured in different parts of the accessible tectum present steep variations in shape and size. These results are helpful to better design and interpret anatomical and physiological experiments involving the pigeon's visual system.

Background One year after the introduction of Information and Communication Technology (ICT) to support diagnostic imaging at our hospital, clinicians had faster and better access to radiology reports and images; direct access to Computed Tomography (CT) reports in the Electronic Medical Record (EMR) was particularly popular. The objective of this study was to determine whether improvements in radiology reporting and clinical access to diagnostic imaging information one year after the ICT introduction were associated with a reduction in the length of patients' hospital stays (LOS). Methods Data describing hospital stays and diagnostic imaging were collected retrospectively from the EMR during periods of equal duration before and one year after the introduction of ICT. The post-ICT period was chosen because of the documented improvement in clinical access to radiology results during that period. The data set was randomly split into an exploratory part used to establish the hypotheses, and a confirmatory part. The data was used to compare the pre-ICT and post-ICT status, but also to compare differences between groups. Results There was no general reduction in LOS one year after ICT introduction. However, there was a 25% reduction for one group - patients with CT scans. This group was heterogeneous, covering 445 different primary discharge diagnoses. Analyses of subgroups were performed to reduce the impact of this divergence. Conclusion Our results did not indicate that improved access to radiology results reduced the patients' LOS. There was, however, a significant reduction in LOS for patients undergoing CT scans. Given the clinicians' interest in CT reports and the results of the subgroup analyses, it is likely that improved access to CT reports contributed to this reduction. PMID:20819224

Flaxseed, rich in the phytoestrogen lignan secoisolariciresinol diglycoside (SDG), provides protection against bone loss at the lumbar vertebrae primarily when combined with low-dose estrogen therapy in the ovariectomized rat model of postmenopausal osteoporosis. Whether SDG metabolites are accessible to skeletal tissue, and thus have the potential to interact with low-dose estrogen therapy to exert direct local action on bone metabolism, is unknown. The objective of this study was to determine whether metabolites of SDG are accessible to the skeleton of ovariectomized rats and to compare the distribution of SDG metabolites in skeletal tissue with that in other tissues. Rats were fed a 10% flaxseed diet and gavaged daily with tritium-labeled SDG (7.4 kBq/g of body weight) in deionized water (500 μL) (n=3) or deionized water alone (n=3) for 7 days, after which tissues were collected for liquid scintillation counting. Radioactivity was detected in similar concentrations in the lumbar vertebrae, femurs, and tibias. Compared with non-skeletal tissues, total radioactivity in the skeleton was significantly lower than in the liver, heart, kidney, thymus, and brain (P < .001). There were no significant differences in levels of radioactivity between skeletal tissue versus the spleen, lung, bladder, uterus, vagina, and mammary gland. In conclusion, SDG metabolites are accessible to skeletal tissue of ovariectomized rats. Thus, it is biologically plausible that SDG metabolites may play a direct role in the protective effects of flaxseed combined with low-dose estrogen therapy against the loss of bone mass and bone strength in the ovariectomized rat model of postmenopausal osteoporosis.

Since 2009, the Federal government distributed over $29 billion to providers who were adopting compliant electronic health record (EHR) technology. With a focus on radiology, we explore how EHR technology impacts interoperability with referring clinicians' EHRs and patient engagement. We also discuss the high-level details of contributing supporting frameworks, specifically Direct messaging and health information service provider (HISP) technology. We characterized Direct messaging, a secure e-mail-like protocol built to allow exchange of encrypted health information online, and the new supporting HISP infrastructure. Statistics related to both the testing and active use of this framework were obtained from DirectTrust.org, an organization whose framework supports Direct messaging use by healthcare organizations. To evaluate patient engagement, we obtained usage data from a radiology-centric patient portal between 2014 and 2015, which in some cases included access to radiology reports. Statistics from 2013 to 2015 showed a rise in issued secure Direct addresses from 8724 to 752,496; a rise in the number of participating healthcare organizations from 667 to 39,751; and a rise in the secure messages sent from 122,842 to 27,316,438. Regarding patient engagement, an average of 234,679 patients per month were provided portal access, with 86,400 patients per month given access to radiology reports. Availability of radiology reports online was strongly associated with increased system usage, with a likelihood ratio of 2.63. The use of certified EHR technology and Direct messaging in the practice of radiology allows for the communication of patient information and radiology results with referring clinicians and increases patient use of patient portal technology, supporting bidirectional radiologist-patient communication.

Breaking and Fixing Origin-Based Access Control in Hybrid Web/Mobile Application Frameworks
Georgiev, Martin; Jana, Suman; Shmatikov, Vitaly
2014-01-01
Hybrid mobile applications (apps) combine the features of Web applications and “native” mobile apps. Like Web applications, they are implemented in portable, platform-independent languages such as HTML and JavaScript. Like native apps, they have direct access to local device resources—file system, location, camera, contacts, etc. Hybrid apps are typically developed using hybrid application frameworks such as PhoneGap. The purpose of the framework is twofold. First, it provides an embedded Web browser (for example, WebView on Android) that executes the app's Web code. Second, it supplies “bridges” that allow Web code to escape the browser and access local resources on the device. We analyze the software stack created by hybrid frameworks and demonstrate that it does not properly compose the access-control policies governing Web code and local code, respectively. Web code is governed by the same origin policy, whereas local code is governed by the access-control policy of the operating system (for example, user-granted permissions in Android). The bridges added by the framework to the browser have the same local access rights as the entire application, but are not correctly protected by the same origin policy. This opens the door to fracking attacks, which allow foreign-origin Web content included into a hybrid app (e.g., ads confined in iframes) to drill through the layers and directly access device resources. Fracking vulnerabilities are generic: they affect all hybrid frameworks, all embedded Web browsers, all bridge mechanisms, and all platforms on which these frameworks are deployed. We study the prevalence of fracking vulnerabilities in free Android apps based on the PhoneGap framework. Each vulnerability exposes sensitive local resources—the ability to read and write contacts list, local files, etc.—to dozens of potentially malicious Web domains. We also analyze the defenses deployed by hybrid frameworks to prevent resource access by foreign-origin Web content and explain why they are ineffectual. We then present NoFrak, a capability-based defense against fracking attacks. NoFrak is platform-independent, compatible with any framework and embedded browser, requires no changes to the code of the existing hybrid apps, and does not break their advertising-supported business model.

Directional frequency analysis and recording (DIFAR) sonobuoys can allow real-time acoustic localization of baleen whales for underwater tracking and remote sensing, but limited availability of hardware and software has prevented wider usage. These software limitations were addressed by developing a module in the open-source software PAMGuard. A case study is presented demonstrating that this software provides greater efficiency and accessibility than previous methods for detecting, localizing, and tracking Antarctic blue whales in real time. Additionally, this software can easily be extended to track other low and mid frequency sounds including those from other cetaceans, pinnipeds, icebergs, shipping, and seismic airguns.

Helping the public find information the U.S. Government Information Locator Service (GILS)
Christian, E.J.
1994-01-01
As part of the National Information Infrastructure, the U.S. federal government is establishing a Government Information Locator Service (GILS). GILS will identify and describe public information resources throughout the federal government and provide assistance in obtaining the information. It will be decentralized and will supplement other agency and commercial information dissemination mechanisms. The public will use GILS directly or through intermediaries, including the Government Printing Office and the National Technical Information Service, as well as federal depository libraries, other public libraries, and private sector information services. Direct users will have access to a GILS Core accessible on the Internet without charge. Intermediate access may include kiosks, 800 numbers, electronic mail, bulletin boards, FAX, and offline media such as floppy disks, CD-ROM, and printed works. GILS will use network technology and the American National Standards Institute Z39.50 standard for information search and retrieval so that information can be retrieved in a variety of ways. Direct users may have access to many other major federal and nonfederal information resources, linkages to data systems, and electronic delivery of information products. An Office of Management and Budget Bulletin in 1994 will provide implementing guidance to agencies. The National Institute of Standards and Technology will also establish a Federal Information Processing Standard specifying a GILS Profile and its application for agencies establishing information locators. ?? 1994.

We examined whether individual-level social capital-the intangible resources in a community available through membership in social networks or other social structures and perceived trust in the community-was associated with acculturation, depression and anxiety symptoms, and perceived access to services among women of Mexican ancestry. Recruited through venue-based targeted sampling in King County, Washington, 205 women of Mexican descent ages 18 to 64 years who differed in socioeconomic status and nativity completed a cross-sectional survey. Half completed the survey in Spanish and half in English. Structural equation modeling was used for model testing. Social capital increased with level of acculturation and was negatively related to depression and anxiety; it had no direct association with perceived access to services. Social capital mediated the relation between acculturation and both depression and anxiety symptoms. Acculturation had no direct association with psychological distress but was directly associated with perceived access to services. This community sample of women reported high levels of psychological distress, with 20% to 26% of women meeting diagnostic criteria for depression or anxiety. Social capital can be assessed at the individual level, increases with acculturation, and may be a potential target for interventions to improve mental health among Mexican American women residing in the United States.

Student Perceptions and Acceptance of Mobile Technology in an Undergraduate Nursing Program
DeCristofaro, Claire; Murphy, Pamela F.; Sims, Archie
2017-01-01
Mobile technology allows healthcare students to access current evidence-based resources. The purpose of this study was to evaluate the student experience of implementing point-of-care (POC) smartphone applications in a first-semester undergraduate nursing program. Teaching methods included using case studies in the laboratory to familiarize students with the apps. At community screening sites, evidence-based guidelines were referenced when students discussed screening results with patients. Surveys were administered prior to implementing this innovation and after the students utilized the apps in direct patient interactions. Survey results were analyzed to evaluate student perceptions and acceptance of mobile technology. Students felt that healthcare smartphone apps were a helpful and convenient way to obtain evidence-based clinical information pertinent to direct care settings. Over 90% of students planned to continue using healthcare smartphone apps. In conclusion, healthcare smartphone apps are a way for students to become comfortable accessing evidence-based clinical resources. It is important to encourage students to use these resources early in the curriculum. Community screenings are an independent health promotion activity which assists in the attainment of health equity and fosters nursing leadership. PMID:28754011

NASA Astrophysics Data System (ADS)
Gadelrab, Karim; Alexander-Katz, Alfredo; LaboratoryTheoretical Soft Materials Team
The self-assembly of block copolymers BCP has provided an impressive control over the nanoscale structure of soft matter. While the main focus of the research in the field has been directed towards simple linear diblocks, the development of advanced polymer architecture provided improved performance and access to new structures. In particular, bottlebrush BCPs (BBCPs) have interesting characteristics due to their dense functionality, high molecular weight, low levels of entanglement, and tendency to efficiently undergo rapid bulk phase separation. In this work, we are interested in theoretically studying the self-assembly of Janus-type ``A-branch-B'' BBCPs where A and B blocks can phase separate with the bottlebrush polymer backbone serving as the interface between the two blocks. Hence, the polymer backbone adds an extra constraint on the equilibrium spacing between neighboring linear diblock chains. In this regard, the segment length of the backbone separating the AB junctions has a direct effect of the observed domain spacing and effective segregation strength of the AB blocks. We employ self-consistent field theoretic SCFT simulations to capture the effect of volume fraction of different constituents and construct a phase diagram of the accessible morphologies of these BBCPs.

Access Control in Location-Based Services
NASA Astrophysics Data System (ADS)
Ardagna, Claudio A.; Cremonini, Marco; de Capitani di Vimercati, Sabrina; Samarati, Pierangela
Recent enhancements in location technologies reliability and precision are fostering the development of a new wave of applications that make use of the location information of users. Such applications introduces new aspects of access control which should be addressed. On the one side, precise location information may play an important role and can be used to develop Location-based Access Control (LBAC) systems that integrate traditional access control mechanisms with conditions based on the physical position of users. On the other side, location information of users can be considered sensitive and access control solutions should be developed to protect it against unauthorized accesses and disclosures. In this chapter, we address these two aspects related to the use and protection of location information, discussing existing solutions, open issues, and some research directions.

The study was conducted to assess the health needs of urban refugees living in İstanbul. A mixed methods approach was adopted to interview Syrian women from households, doctors, decision makers and NGO representatives. The data were collected between June and October 2015. The main challenges were the cost of living in İstanbul, increased rent and language barrier. Almost half (49.6%) of the interviewed women did not know about free health care rights for Syrians. In the last 30 days preceding the interview, 58.6% of the participants sought health care primarily through state hospitals, primary health care centres and pharmacies. The participants had difficulty in accessing health care due to the language barrier and a lack of knowledge of the Turkish health care system. Waiting time at hospitals and negative attitudes of health care staff reduced satisfaction in these services. In relation to life in Turkey, the main issues for Syrian refugees were not directly related to health. They have been given the right to access health care, although had many difficulties in understanding and accessing services in a crowded city.

Stunting results from decreased food intake, poor diet quality, and a high burden of early childhood infections, and contributes to significant morbidity and mortality worldwide. Although food insecurity is an important determinant of child nutrition, including stunting, development of universal measures has been challenging due to cumbersome nutritional questionnaires and concerns about lack of comparability across populations. We investigate the relationship between household food access, one component of food security, and indicators of nutritional status in early childhood across eight country sites. We administered a socioeconomic survey to 800 households in research sites in eight countries, including a recently validated nine-item food access insecurity questionnaire, and obtained anthropometric measurements from children aged 24 to 60 months. We used multivariable regression models to assess the relationship between household food access insecurity and anthropometry in children, and we assessed the invariance of that relationship across country sites. Average age of study children was 41 months. Mean food access insecurity score (range: 0-27) was 5.8, and varied from 2.4 in Nepal to 8.3 in Pakistan. Across sites, the prevalence of stunting (42%) was much higher than the prevalence of wasting (6%). In pooled regression analyses, a 10-point increase in food access insecurity score was associated with a 0.20 SD decrease in height-for-age Z score (95% CI 0.05 to 0.34 SD; p = 0.008). A likelihood ratio test for heterogeneity revealed that this relationship was consistent across countries (p = 0.17). Our study provides evidence of the validity of using a simple household food access insecurity score to investigate the etiology of childhood growth faltering across diverse geographic settings. Such a measure could be used to direct interventions by identifying children at risk of illness and death related to malnutrition.
