Non-Blocking Concurrent Imperative Programming with Session Types

Directory of Open Access Journals (Sweden)

Miguel Silva

2017-01-01

Full Text Available Concurrent C0 is an imperative programming language in the C family with session-typed message-passing concurrency. The previously proposed semantics implements asynchronous (non-blocking output; we extend it here with non-blocking input. A key idea is to postpone message reception as much as possible by interpreting receive commands as a request for a message. We implemented our ideas as a translation from a blocking intermediate language to a non-blocking language. Finally, we evaluated our techniques with several benchmark programs and show the results obtained. While the abstract measure of span always decreases (or remains unchanged, only a few of the examples reap a practical benefit.

The Concert system - Compiler and runtime technology for efficient concurrent object-oriented programming

Science.gov (United States)

Chien, Andrew A.; Karamcheti, Vijay; Plevyak, John; Sahrawat, Deepak

1993-01-01

Concurrent object-oriented languages, particularly fine-grained approaches, reduce the difficulty of large scale concurrent programming by providing modularity through encapsulation while exposing large degrees of concurrency. Despite these programmability advantages, such languages have historically suffered from poor efficiency. This paper describes the Concert project whose goal is to develop portable, efficient implementations of fine-grained concurrent object-oriented languages. Our approach incorporates aggressive program analysis and program transformation with careful information management at every stage from the compiler to the runtime system. The paper discusses the basic elements of the Concert approach along with a description of the potential payoffs. Initial performance results and specific plans for system development are also detailed.

Rain: A New Concurrent Process-Oriented Programming Language

OpenAIRE

Brown, Neil C.C.

2006-01-01

This paper details the design of a new concurrent process-oriented programming language, Rain. The language borrows heavily from occam-p and C++ to create a new language based on process-oriented programming, marrying channel-based communication, a clear division between statement and expression, and elements of functional programming. An expressive yet simple type system, coupled with templates, underpins the language. Modern features such as Unicode support and 64-bit integers are included ...

Reforming Access: Trends in Medicaid Enrollment for New Medicare Beneficiaries, 2008-2011.

Science.gov (United States)

Keohane, Laura M; Rahman, Momotazur; Mor, Vincent

2016-04-01

To evaluate whether aligning the Part D low-income subsidy and Medicaid program enrollment pathways in 2010 increased Medicaid participation among new Medicare beneficiaries. Medicare enrollment records for years 2007-2011. We used a multinomial logistic model with state fixed effects to examine the annual change in limited and full Medicaid enrollment among new Medicare beneficiaries for 2 years before and after the reforms (2008-2011). We identified new Medicare beneficiaries in the years 2008-2011 and their participation in Medicaid based on Medicare enrollment records. The percentage of beneficiaries enrolling in limited Medicaid at the start of Medicare coverage increased in 2010 by 0.3 percentage points for individuals aging into Medicare and by 1.3 percentage points for those qualifying due to disability (p < .001). There was no significant difference in the size of enrollment increases between states with and without concurrent limited Medicaid eligibility expansions. Our findings suggest that streamlining financial assistance programs may improve Medicare beneficiaries' access to benefits. © Health Research and Educational Trust.

Enrolling Underserved Women in mHealth Programs: Results From Text4baby Outreach Campaigns.

Science.gov (United States)

Bushar, Jessica A; Fishman, Jodie; Garfinkel, Danielle; Pirretti, Amy

2018-03-01

Public health practitioners have increasingly leveraged technology-based communication to get health information into the hands of hard-to-reach populations; however, best practices for outreach and enrollment into mobile health (mHealth) programs are lacking. This article describes enrollment results from campaigns focused on enrolling underserved pregnant women and mothers in Text4baby-a free, mHealth service-to inform outreach strategies for mHealth programs. Text4baby participants receive health and safety information, interactive surveys, alerts, and appointment reminders through at least three weekly texts and a free app-timed to users' due date or babies' birth date. Text4baby worked with partners to implement national, state, and community-based enrollment campaigns. Descriptive statistics were used to compare baseline enrollment prior to a campaign with enrollment during a campaign to generate enrollment estimates. Enrollment rates were calculated for campaigns for which the number targeted/reached was available. National television campaigns resulted in more than 10,000 estimated enrollments. Campaigns that were integrated with an existing program and text-based recruitment had the highest enrollment rates, ranging from 7% to 24%. Facebook advertisements and traditional media targeting providers and consumers were least effective. mHealth programs should consider text-based recruitment and outreach via existing programs; additional research is needed on return on investment for different outreach strategies and on the effectiveness of different outreach strategies at reaching and enrolling specific target populations.

Relaxed Operational Semantics of Concurrent Programming Languages

Directory of Open Access Journals (Sweden)

Gustavo Petri

2012-08-01

Full Text Available We propose a novel, operational framework to formally describe the semantics of concurrent programs running within the context of a relaxed memory model. Our framework features a "temporary store" where the memory operations issued by the threads are recorded, in program order. A memory model then specifies the conditions under which a pending operation from this sequence is allowed to be globally performed, possibly out of order. The memory model also involves a "write grain," accounting for architectures where a thread may read a write that is not yet globally visible. Our formal model is supported by a software simulator, allowing us to run litmus tests in our semantics.

Visualization of independence and dependence for program concurrency

International Nuclear Information System (INIS)

Belady, L.A.; Hosokawa, K.

1984-01-01

In order to fully utilize the CRT device's dynamic and two dimensional capabilities, a new way of thinking about programs and an associated notation are proposed. The scheme permits the explicit indication of the program's potential for parallel execution. The image created by the programmer on the screen provides the compiler with sequencing and concurrency information, while at the same time serves as a visual feedback to the programmer. So far the way of programming in two dimensions is just an idea and has not yet been tried either on a real life problem or by employing real life programmers. The authors are attempting a quick implementation in the form of a front end to an existing language

Luder, Heidi; Frede, Stacey; Kirby, James; King, Keith; Heaton, Pamela

2016-08-01

The purpose of this study was to survey new enrollees in a community pharmacy, employer-based diabetes and hypertension coaching program to describe the characteristics, health beliefs, and cues to action of newly enrolled participants. A 70-question, 5-point Likert-type survey was developed using constructs from the Health Belief Model (HBM), Theory of Planned Behavior (TPB), and Theory of Reasoned Action (TRA). New enrollees in the coaching programs completed the survey. Survey responses between controlled and uncontrolled patients and patient demographics were compared. Between November 2011 and November 2012, 154 patients completed the survey. Patients were fairly well controlled with a mean hemoglobin A1C of 7.3% and a mean blood pressure of 134/82 mm Hg. The strongest cue to action for enrollment was the financial incentives offered by the employer (mean: 3.33, median: 4). White patients were significantly more motivated by financial incentives. More patients indicated they had not enrolled previously in the program because they were unaware it was available (mean: 2.89, median 3.0) and these patients were more likely to have an uncontrolled condition (P ≤ 0.050). A top factor motivating patients to enroll in a disease management coaching program was the receipt of financial incentives. Significant differences in HBM, TPB, and TRA responses were seen for patients with different demographics. © The Author(s) 2015.

A Tutorial on Parallel and Concurrent Programming in Haskell

Science.gov (United States)

Peyton Jones, Simon; Singh, Satnam

This practical tutorial introduces the features available in Haskell for writing parallel and concurrent programs. We first describe how to write semi-explicit parallel programs by using annotations to express opportunities for parallelism and to help control the granularity of parallelism for effective execution on modern operating systems and processors. We then describe the mechanisms provided by Haskell for writing explicitly parallel programs with a focus on the use of software transactional memory to help share information between threads. Finally, we show how nested data parallelism can be used to write deterministically parallel programs which allows programmers to use rich data types in data parallel programs which are automatically transformed into flat data parallel versions for efficient execution on multi-core processors.

An inmate cannot sue the Taylorville Correctional Center in Illinois under the Americans with Disabilities Act (ADA) for requiring an HIV test for enrollment in a prison program. [Name removed] wanted to participate in the prison's culinary arts program, but did not want to take the HIV test. The 7th U.S. Circuit Court of Appeals ruled that [name removed] was not a "qualified individual with a disability" and therefore could not sue under ADA. The policy justification for the HIV test, which is required of all inmates enrolling in the program, was not addressed by the court.

The proliferation of shared mutable state in object-oriented programming complicates software development as two seemingly unrelated operations may interact via an alias and produce unexpected results. In concurrent programming this manifests itself as data-races. Concurrent object-oriented programming further suffers from the fact that code that warrants synchronisation cannot easily be distinguished from code that does not. The burden is placed solely on the programmer to reason ab...

Smith, Anita

2010-01-01

Technological advances assist in the proliferation of online nursing programs which meet the needs of the working nurse. Understanding online learning styles permits universities to adequately address the educational needs of the professional nurse returning for an advanced degree. The purpose of this study was to describe the learning styles of registered nurses (RNs) enrolled in an online master's nursing program or RN-bachelor of science in nursing (BSN) program. A descriptive, cross-sectional design was used. Kolb's learning style inventory (Version 3.1) was completed by 217 RNs enrolled in online courses at a Southeastern university. Descriptive statistical procedures were used for analysis. Thirty-one percent of the nurses were accommodators, 20% were assimilators, 19% were convergers, and 20% were divergers. Accommodators desire hand-on experiences, carrying out plans and tasks and using an intuitive trial-and-error approach to problem solving. The learning styles of the RNs were similar to the BSN students in traditional classroom settings. Despite their learning style, nurses felt that the online program met their needs. Implementing the technological innovations in nursing education requires the understanding of the hands-on learning of the RN so that the development of the online courses will satisfactorily meet the needs of the nurses who have chosen an online program.

Concurrent LISP and its interpreter

Energy Technology Data Exchange (ETDEWEB)

Tabata, K; Sugimoto, S; Ohno, Y

1981-01-01

In the research field of artificial intelligence many languages have been developed based on LISP, such as Planner, Conniver and so on. They have been developed to give users many useful facilities, especially for describing flexible control structures. Backtracking and coroutine facilities are typical ones introduced into these languages. Compared with backtracking and coroutine facilities, multi-process description facilities are considered to be a better alternative for writing well-structured programs. This paper describes concurrent LISP, a new concurrent programming language based on LISP. Concurrent LISP is designed to provide simple and flexible facilities for multi-process description without changing the original language features of LISP. This paper also describes the concurrent LISP interpreter which has been implemented on a FACOM M-200 at the Data Processing Center of Kyoto University. 19 references.

To determine whether concurrently performed operations are associated with an increased risk for adverse events. Concurrent operations occur when a surgeon is simultaneously responsible for critical portions of 2 or more operations. How this practice affects patient outcomes is unknown. Using American College of Surgeons' National Surgical Quality Improvement Program data from 2014 to 2015, operations were considered concurrent if they overlapped by ≥60 minutes or in their entirety. Propensity-score-matched cohorts were constructed to compare death or serious morbidity (DSM), unplanned reoperation, and unplanned readmission in concurrent versus non-concurrent operations. Multilevel hierarchical regression was used to account for the clustered nature of the data while controlling for procedure and case mix. There were 1430 (32.3%) surgeons from 390 (77.7%) hospitals who performed 12,010 (2.3%) concurrent operations. Plastic surgery (n = 393 [13.7%]), otolaryngology (n = 470 [11.2%]), and neurosurgery (n = 2067 [8.4%]) were specialties with the highest proportion of concurrent operations. Spine procedures were the most frequent concurrent procedures overall (n = 2059/12,010 [17.1%]). Unadjusted rates of DSM (9.0% vs 7.1%; P < 0.001), reoperation (3.6% vs 2.7%; P < 0.001), and readmission (6.9% vs 5.1%; P < 0.001) were greater in the concurrent operation cohort versus the non-concurrent. After propensity score matching and risk-adjustment, there was no significant association of concurrence with DSM (odds ratio [OR] 1.08; 95% confidence interval [CI] 0.96-1.21), reoperation (OR 1.16; 95% CI 0.96-1.40), or readmission (OR 1.14; 95% CI 0.99-1.29). In these analyses, concurrent operations were not detected to increase the risk for adverse outcomes. These results do not lessen the need for further studies, continuous self-regulation and proactive disclosure to patients.

Differences between African-American and Caucasian students on enrollment influences and barriers in kinesiology-based allied health education programs.

Barfield, J P; Cobler, D C; Lam, Eddie T C; Zhang, James; Chitiyo, George

2012-06-01

Kinesiology departments have recently started to offer allied health education programs to attract additional students to teacher education units (9). Although allied health professions offer increased work opportunities, insufficient enrollment and training of minority students in these academic fields contribute to underrepresentation in the workforce (3). To improve workforce diversity, kinesiology departments must understand how enrollment influences and barriers differ by race among prospective students. Therefore, the purpose of this study was to identify differences in allied health education enrollment influences and enrollment barriers between minority and Caucasian students. Participants (n = 601) consisted of students enrolled in kinesiology-based allied health education programs. Multivariate ANOVA was used to compare group differences in enrollment decision making. "Personal influence," "career opportunity," and "physical self-efficacy" were all significantly stronger enrollment influences among African-American students than among Caucasian students, and "social influence," "experiential opportunity," "academic preparation," and "physical self-efficacy" were all perceived as significantly greater barriers compared with Caucasian students. Findings support the need to recruit African-American students through sport and physical education settings and to market program-based experiential opportunities.

2017-11-14

Since 2012, a large health care system has offered an employee wellness program providing premium discounts for those who voluntarily undergo biometric screenings and meet goals. This study evaluates the program impact on care utilization and total cost of care, taking into account employee self-selection into the program. A retrospective claims data analysis of 6453 employees between 2011 and 2015 was conducted, categorizing the sample into 3 mutually exclusive subgroups: Subgroup 1 enrolled and met goals in all years, Subgroup 2 enrolled or met goals in some years but not all, and Subgroup 3 never enrolled. Each subgroup was compared to a cohort of employees in other employer groups (N = 24,061). Using a difference-in-difference method, significant reductions in total medical cost (14.2%; P = 0.014) and emergency department (ED) visits (11.2%; P = 0.058) were observed only among Subgroup 2 in 2015. No significant impact was detected among those in Subgroup 1. Those in Subgroup 1 were less likely to have chronic conditions at baseline. The results indicate that the wellness program enrollment was characterized by self-selection of healthier employees, among whom the program appeared to have no significant impact. Yet, cost savings and reductions in ED visits were observed among the subset of employees who enrolled or met goal in some years but not all, suggesting a potential link between the wellness program and positive behavior changes among certain subsets of the employee population.

The tools used for program evaluation are shown too. Despite the low participation, it has been a framework for the development of various educational and socializing activities (for mentors and mentees focused on developing generic competences. Furthermore, it has been a research tool to get a better understanding of problems affecting students newly enrolled.

Automation through the PIP [Program Implementation Plan] concurrence system improves information sharing among DOE [Dept. of Energy] managers

International Nuclear Information System (INIS)

Imholz, R.M.; Berube, D.S.; Peterson, J.L.

1990-01-01

The Program Implementation Plan (PIP) Concurrence System is designed to improve information sharing within the U.S. Department of Energy (DOE) and between DOE and the Field. Effectively sharing information enables DOE managers to make more informed, effective decisions. The PIP Concurrence System improved information sharing among DOE managers by defining the automated process for concurring on a DOE document, thus reducing the time required to concur on the document by 75%. The first step in defining an automated process is to structure the process for concurring on a document. Only those DOE managers with approved access could review certain parts of a document on a concurrence system. Remember that the concurrence process is a sign off procedure unlike a commentary process in which comments may not be restricted to certain people. The commentary process is the beginning of the concurrence process. The commentary process builds a document; the concurrence process approves it. 6 refs., 7 figs

The aim of this study was to investigate the association between postnatal depression (PND) symptoms severity and structural neighborhood characteristics among women enrolled in a home visiting program. The sample included 295 mothers who were at risk for developing PND, observed as 3-month Edinburgh Postnatal Depression Scale (EPDS) scores ≥ 10. Two neighborhood predictor components (residential stability and social disadvantage) were analyzed as predictors of PND symptom severity using a generalized estimating equation. Residential stability was negatively associated with PND symptom severity. Social disadvantage was not found to be statistically significantly. The findings suggest that residential stability is associated with a reduction in PND symptom severity for women enrolled in home visiting program.

2017-01-01

Continuing professional development is an essential element in professional nursing practice. In our Hospital and Health service, a gap in existing nursing pathways was identified for Assistants in Nursing (AINs), who wished to further their career in nursing and progress to Enrolled Nurse (EN). There is also little in the literature that addresses Assistants in Nursing wishing to progress their career to Enrolled Nurses. This article describes a quality improvement project designed to address this gap. The project was a collaborative venture between a Queensland Hospital and Health Service and an Institute of Tertiary and Further Education (TAFE). The focus was on creating a flexible career path for Assistants in Nursing, wishing to become Enrolled Nurses. The project resulted in the Diploma of Nursing program (theory and practice) being delivered within the hospital setting by nurse educators and clinical nurse consultants. This is unusual in that the program is normally delivered in the tertiary setting, by academic staff from the Institute of Further Education. Program implementation is described along with the challenges encountered. Outcomes from the project were: 78% completion rate; 100% employment on completion of their course of study; and 18% progressing to further their education such as Advance Enrolled Nurse or Registered Nurse. Student satisfaction regarding the program was also positive. The initiative established a local career path for Assistants in Nursing wishing to progress to Enrolled Nurse. This quality project demonstrates that collaborative ventures between the tertiary sector and hospital and health services, can create innovative flexible solutions for staff wishing to further their career in nursing.

International Nuclear Information System (INIS)

Shan Lu; Soyeon Park; Eunsoo Seo; Yuanyuan Zhou

2008-01-01

The reality of multi-core hardware has made concurrent programs pervasive. Unfortunately, writing correct concurrent programs is difficult. Addressing this challenge requires advances in multiple directions, including concurrency bug detection, concurrent program testing, concurrent programming model design, etc. Designing effective techniques in all these directions will significantly benefit from a deep understanding of real world concurrency bug characteristics. This paper provides the first (to the best of our knowledge) comprehensive real world concurrency bug characteristic study. Specifically, we have carefully examined concurrency bug patterns, manifestation, and fix strategies of 105 randomly selected real world concurrency bugs from 4 representative server and client opensource applications (MySQL, Apache, Mozilla and OpenOffice). Our study reveals several interesting findings and provides useful guidance for concurrency bug detection, testing, and concurrent programming language design. Some of our findings are as follows: (1) Around one third of the examined non-deadlock concurrency bugs are caused by violation to programmers order intentions, which may not be easily expressed via synchronization primitives like locks and transactional memories; (2) Around 34% of the examined non-deadlock concurrency bugs involve multiple variables, which are not well addressed by existing bug detection tools; (3) About 92% of the examined concurrency bugs can be reliably triggered by enforcing certain orders among no more than 4 memory accesses. This indicates that testing concurrent programs can target at exploring possible orders among every small groups of memory accesses, instead of among all memory accesses; (4) About 73% of the examined non-deadlock concurrency bugs were not fixed by simply adding or changing locks, and many of the fixes were not correct at the first try, indicating the difficulty of reasoning concurrent execution by programmers.

To achieve that, we show that it is possible to relax some of the requirements imposed by original formulation of those techniques without compromising...... such a language. We also introduce an abstract domain that symbolically represents the messages sent between the concurrently executing processes.

Reconciling pairs of concurrently used clinical practice guidelines using Constraint Logic Programming.

Science.gov (United States)

Wilk, Szymon; Michalowski, Martin; Michalowski, Wojtek; Hing, Marisela Mainegra; Farion, Ken

2011-01-01

This paper describes a new methodological approach to reconciling adverse and contradictory activities (called points of contention) occurring when a patient is managed according to two or more concurrently used clinical practice guidelines (CPGs). The need to address these inconsistencies occurs when a patient with more than one disease, each of which is a comorbid condition, has to be managed according to different treatment regimens. We propose an automatic procedure that constructs a mathematical guideline model using the Constraint Logic Programming (CLP) methodology, uses this model to identify and mitigate encountered points of contention, and revises the considered CPGs accordingly. The proposed procedure is used as an alerting mechanism and coupled with a guideline execution engine warns the physician about potential problems with the concurrent application of two or more guidelines. We illustrate the operation of our procedure in a clinical scenario describing simultaneous use of CPGs for duodenal ulcer and transient ischemic attack.

Community health events for enrolling uninsured into public health insurance programs: implications for health reform.

Cheng, Scott; Tsai, Kai-ya; Nascimento, Lori M; Cousineau, Michael R

2014-01-01

To determine whether enrollment events may serve as a venue to identify eligible individuals, enroll them into health insurance programs, and educate them about the changes the Patient Protection and Affordable Care Act will bring about. More than 2900 surveys were administered to attendees of 7 public health insurance enrollment events in California. Surveys were used to identify whether participants had any change in understanding of health reform after participating in the event. More than half of attendees at nearly all events had no knowledge about health reform before attending the event. On average, more than 80% of attendees knew more about health reform following the event and more than 80% believed that the law would benefit their families. Enrollment events can serve as an effective method to educate the public on health reform. Further research is recommended to explore in greater detail the impact community enrollment events can have on expanding public understanding of health reform.

Reducing cultural and psychological barriers to Latino enrollment in HIV-prevention counseling: initial data on an enrollment meta-intervention.

Science.gov (United States)

Wilson, Kristina; Durantini, Marta R; Albarracín, Julia; Crause, Candi; Albarracín, Dolores

2013-01-01

Aspects of Latino culture (e.g., machismo, marianism) can act as barriers to enrollment in HIV-prevention programs. To lift these barriers, a culturally appropriate meta-intervention was designed to increase intentions to enroll in HIV-prevention counseling by Latinos. Latino participants (N=41) were recruited from the community and randomly assigned to either an experimental or control meta-intervention condition that varied the introduction to a HIV-prevention counseling program. Following the meta-intervention, participants were issued an invitation to take part in HIV-prevention counseling. The outcome measure was the intention to enroll in a HIV-prevention counseling session. Findings indicated that enrollment intentions were higher in the experimental meta-intervention condition (96%) than in the control meta-intervention condition (53%). In addition, the effects of the meta-intervention were comparable across genders and participant ages. Findings suggest that the use of a culturally appropriate meta-intervention may be an effective strategy for increasing Latino enrollment in HIV-prevention programs. These promising findings warrant further investigation into the efficacy and effectiveness of this meta-intervention.

How Formal Dynamic Verification Tools Facilitate Novel Concurrency Visualizations

Science.gov (United States)

Aananthakrishnan, Sriram; Delisi, Michael; Vakkalanka, Sarvani; Vo, Anh; Gopalakrishnan, Ganesh; Kirby, Robert M.; Thakur, Rajeev

With the exploding scale of concurrency, presenting valuable pieces of information collected by formal verification tools intuitively and graphically can greatly enhance concurrent system debugging. Traditional MPI program debuggers present trace views of MPI program executions. Such views are redundant, often containing equivalent traces that permute independent MPI calls. In our ISP formal dynamic verifier for MPI programs, we present a collection of alternate views made possible by the use of formal dynamic verification. Some of ISP’s views help pinpoint errors, some facilitate discerning errors by eliminating redundancy, while others help understand the program better by displaying concurrent even orderings that must be respected by all MPI implementations, in the form of completes-before graphs. In this paper, we describe ISP’s graphical user interface (GUI) capabilities in all these areas which are currently supported by a portable Java based GUI, a Microsoft Visual Studio GUI, and an Eclipse based GUI whose development is in progress.

Charity, Pamela C.; Klein, Paul B.; Wadhwa, Bhushan

1995-01-01

The Cleveland State University Minority Engineering Program Pipeline consist of programs which foster engineering career awareness, academic enrichment, and professional development for historically underrepresented minority studies. The programs involved are the Access to Careers in Engineering (ACE) Program for high school pre-engineering students: the LINK Program for undergraduate students pursuing degree which include engineering; and the PEP (Pre-calculus Enrichment Program) and EPIC (Enrichment Program in Calculus) mathematics programs for undergraduate academic enrichment. The pipeline is such that high school graduates from the ACE Program who enroll at Cleveland State University in pursuit of engineering degrees are admitted to the LINK Program for undergraduate level support. LINK Program students are among the minority participants who receive mathematics enrichment through the PEP and EPIC Programs for successful completion of their engineering required math courses. THese programs are interdependent and share the goal of preparing minority students for engineering careers by enabling them to achieve academically and obtain college degree and career related experience.

2017-01-01

Purpose: To perform a prospective trial testing the feasibility and utility of acquiring activity data as a measure of health status during concurrent chemoradiotherapy. Methods and Materials: Ambulatory patients who were planned for treatment with concurrent chemoradiotherapy with curative intent for cancers of the head and neck, lung, or gastrointestinal tract were provided with activity monitors before treatment initiation. Patients were asked to wear the devices continuously throughout the radiation therapy course. Step count data were downloaded weekly during radiation therapy and 2 and 4 weeks after radiation therapy completion. The primary objective was to demonstrate feasibility, defined as collection of step counts for 80% of the days during study subjects' radiation therapy courses. Secondary objectives included establishing step count as a dynamic predictor of unplanned hospitalization risk. Results: Thirty-eight enrolled patients were treated with concurrent chemoradiotherapy. Primary diagnoses included head and neck cancer (n=11), lung cancer (n=13), and a variety of gastrointestinal cancers (n=14). Step data were collected for 1524 of 1613 days (94%) during patients' radiation therapy courses. Fourteen patients were hospitalized during radiation therapy or within 4 weeks of radiation therapy completion. Cox regression modeling demonstrated a significant association between recent step counts (3-day average) and hospitalization risk, with a 38% reduction in the risk of hospitalization for every 1000 steps taken each day (hazard ratio 0.62, 95% confidence interval 0.46-0.83, P=.002). Inferior quality of life scores and impaired performance status were not associated with increased hospitalization risk. Conclusion: Continuous activity monitoring during concurrent chemoradiotherapy is feasible and well-tolerated. Step counts may serve as powerful, objective, and dynamic indicators of hospitalization risk.

Full Text Available Objectives: To investigate barriers to utilization of a pharmacist-led fitness, nutrition, and weight management coaching program, as well as describe patient reported expectations and explore the patient characteristics potentially associated with a higher willingness to participate in the future. Design: Cross-sectional, descriptive study using an anonymous, electronic survey. Setting: A large, national, grocery store chain. Participants: Employee benefit plan members, eligible for a pharmacist-led fitness, nutrition, and weight management (FNWM coaching program, who were not currently or previously enrolled in the program, and met coaching program qualifications. Intervention: Peer-reviewed, electronic survey administered and collected using an Internet survey analysis software. Main Outcome Measures: Barriers to enrollment in the pharmacist-led fitness, nutrition, and weight management coaching program. Results: Of 1,130 emailed employees, 352 responded and 133 met study inclusion criteria and completed the whole survey. Of those who fit inclusion criteria, the majority (53.4% of the respondents were aware of the coaching program (75.2% and expressed interest in future participation (53.4%. “I am already taking steps to improve my health” and “I do not have time to participate in the program” were the highest rated barriers for both those interested and not interested in participating in the coaching program. The majority of participants believed pharmacists were qualified to provide the coaching service (78.2% and preferred one-on-one coaching with the pharmacist (67.7%. Key topics respondents wanted the pharmacist to cover included general diet and nutrition, weight management strategies, and vitamins and supplements. Conclusion: The two major barriers reported in the study were lack of time and the use of other health improvement methods; however, a large number of respondents indicated future interest in participating.

Okhomina, Victoria I; Seals, Samantha R; Marshall, Gailen D

2018-04-03

Randomized controlled trials (RCT) often employ multiple recruitment methods to attract participants, however, special care must be taken to be inclusive of under-represented populations. We examine how recruiting from an existing observational study affected the recruitment of African Americans into a RCT that included yoga-based interventions. In particular, we report the recruitment success of The Effects of Health Promoting Programs (HPP) on Cardiovascular Disease Risk (NCT02019953), the first yoga-based clinical trial to focus only on African Americans. To recruit participants, a multifaceted recruitment strategy was implemented exclusively in the Jackson Heart Study (JHS) cohort. The HPP recruited from the JHS cohort using direct mailings, signs and flyers placed around JHS study facilities, and through JHS annual follow-up interviews. Enrollment into HPP was open to all active JHS participants that were eligible to return for the third clinic exam (n = 4644). The target sample size was 375 JHS participants over a 24 month recruitment and enrollment period. From the active members of the JHS cohort, 503 were pre-screened for eligibility in HPP. More than 90% of those pre-screened were provisionally eligible for the study. The enrollment goal of 375 was completed after a 16-month enrollment period with over 25% (n = 97) of the required sample size enrolling during the second month of recruitment. The findings show that participants in observational studies can be successfully recruited into RCT. Observational studies provide researchers with a well-defined population that may be of interest when designing clinical trials. This is particularly useful in the recruitment of a high-risk, traditionally underrepresented populations for non-pharmacological clinical trials where traditional recruitment methods may prolong enrollment periods and extend study budgets.

2016-04-01

In the latter half of the 20th century, registered nurse education moved to university degree level. As a result, there has been a reduction in access for students to clinical experience. In numerous studies, nursing graduates have reported that they do not feel prepared for practice. The importance of maximising every learning opportunity during nursing school is paramount. At Edith Cowan University, a program was initiated that allows students to become enrolled nurses at the midway point of their degree to enable them to work and therefore gain experience in the clinical practice setting during their education. This study investigated the effect of the program on the nursing students' perception of their clinical abilities and explored their ability to link theory to practice. The research design for this study was a quasi-experimental, prospective observational cohort study. The study included 39 second-year nursing students not enrolled in the program (Group 1), 45 second-year nursing students enrolled in the program (Group 2), and 28 third-year nursing students who completed the program and are working as enrolled nurses (Group 3). Participants were asked to complete a Five Dimension of Nursing Scale questionnaire. The quantitative analyses showed that students in Group 1 had statistically significant higher pre-questionnaire perceived abilities across all domains, except in two dimensions when compared to Group 2. The post-questionnaire analysis showed that Group 1 had statistically significant lower perceived abilities in four of the five dimensions compared to Group 2. Group 1 also had significantly lower abilities in all dimensions compared to Group 3. Group 3 had a significantly higher perception of their clinical abilities compared to Group 2. This study highlights the value of meaningful employment for undergraduate nursing students by providing opportunities to increase confidence in clinical abilities. Copyright © 2016 Elsevier Ltd.

Measuring and modelling concurrency

Science.gov (United States)

Sawers, Larry

2013-01-01

This article explores three critical topics discussed in the recent debate over concurrency (overlapping sexual partnerships): measurement of the prevalence of concurrency, mathematical modelling of concurrency and HIV epidemic dynamics, and measuring the correlation between HIV and concurrency. The focus of the article is the concurrency hypothesis – the proposition that presumed high prevalence of concurrency explains sub-Saharan Africa's exceptionally high HIV prevalence. Recent surveys using improved questionnaire design show reported concurrency ranging from 0.8% to 7.6% in the region. Even after adjusting for plausible levels of reporting errors, appropriately parameterized sexual network models of HIV epidemics do not generate sustainable epidemic trajectories (avoid epidemic extinction) at levels of concurrency found in recent surveys in sub-Saharan Africa. Efforts to support the concurrency hypothesis with a statistical correlation between HIV incidence and concurrency prevalence are not yet successful. Two decades of efforts to find evidence in support of the concurrency hypothesis have failed to build a convincing case. PMID:23406964

Full Text Available The present study aimed to identify the causes and motives of Yarmouk University students to enroll in graduate programs of educational disciplines in Jordan. Ten students (6 males and 4 females participated in the study. The study used qualitative research method by means of in-depth interviews during which the participants were given various open questions in each session so as to express their views about the issue under investigation. After the analysis of participants’ responses, it was found that they focused on the following motives: career advancement; creation of wider job opportunities; social motivation, which focuses on improving the social status; formation of social relationships; friends and family’s encouragement to pursue graduate studies. Then economic motives were brought in by the participants, who believed that to get a graduate degree would increase their income, career promotion, personal living standards, and job opportunities abroad. The results also pointed to the role of psychological motivation for admission to the College of Graduate Studies. This would provide psychological stability and satisfaction, and self-esteem. There was also a reference to the admission policies at universities which became more flexible than before, whereby standards have also changed. This made admission more open than before, which encouraged more students to apply to graduate programs. They also added that in view of these standards and policies, it is clear that more students will apply to the graduate programs in the future; and other new disciplines would be opened in the future as well.

Mishra, Abhay Nath; Ketsche, Patricia; Marton, James; Snyder, Angela; McLaren, Susan

2014-01-01

To assess the perceived readiness of Medicaid and Children's Health Insurance Program (CHIP) enrollees to use information technologies (IT) in order to facilitate improvements in the application processes for these public insurance programs. We conducted a concurrent mixed method study of Medicaid and CHIP enrollees in a southern state. We conducted focus groups to identify enrollee concerns regarding the current application process and their IT proficiency. Additionally, we surveyed beneficiaries via telephone about their access to and use of the Internet, and willingness to adopt IT-enabled processes. 2013 households completed the survey. We used χ(2) analysis for comparisons across different groups of respondents. A majority of enrollees will embrace IT-enabled enrollment, but a small yet significant group continues to lack access to facilitating technologies. Moreover, a segment of beneficiaries in the two programs continues to place a high value on personal interactions with program caseworkers. IT holds the promise of improving efficiency and reducing barriers for enrollees, but state and federal agencies managing public insurance programs need to ensure access to traditional processes and make caseworkers available to those who require and value such assistance, even after implementing IT-enabled processes. The use of IT-enabled processes is essential for effectively managing eligibility and enrollment determinations for public programs and private plans offered through state or federally operated exchanges. However, state and federal officials should be cognizant of the technological readiness of recipients and provide offline help to ensure broad participation in the insurance market.

2018-03-16

The introduction of the Affordable Care Act (ACA) has provided unprecedented opportunities for uninsured people with HIV infection to access health insurance, and to examine the impact of this change in access. AIDS Drug Assistance Programs (ADAPs) have been directed to pursue uninsured individuals to enroll in the ACA as both a cost-saving strategy and to increase patient access to care. We evaluated the impact of ADAP-facilitated health insurance enrollment on health outcomes, and demographic and clinical factors that influenced whether or not eligible patients enrolled. During the inaugural open enrollment period for the ACA, 284 Nebraska ADAP recipients were offered insurance enrollment; 139 enrolled and 145 did not. Comparisons were conducted and multivariate models were developed considering factors associated with enrollment and differences between the insured and uninsured groups. Insurance enrollment was associated with improved health outcomes after controlling for other variables, and included a significant association with undetectable viremia, a key indicator of treatment success (p insurance. The National HIV/AIDS Strategy calls for new interventions to improve HIV health outcomes for disproportionately impacted populations. This study provides evidence to prioritize future ADAP-facilitated insurance enrollment strategies to reach minority populations and unstably housed individuals.

In 2010, California launched Partners for Children (PFC), a pediatric palliative care pilot program offering hospice-like services for children eligible for full-scope Medicaid delivered concurrently with curative care, regardless of the child's life expectancy. We assessed the change from before PFC enrollment to the enrolled period in 1) health care costs per enrollee per month (PEPM), 2) costs by service type and diagnosis category, and 3) health care utilization (days of inpatient care and length of hospital stay). A pre-post analysis compared enrollees' health care costs and utilization up to 24 months before enrollment with their costs during participation in the pilot, from January 2010 through December 2012. Analyses were conducted using paid Medicaid claims and program enrollment data. The average PEPM health care costs of program enrollees decreased by $3331 from before their participation in PFC to the enrolled period, driven by a reduction in inpatient costs of $4897 PEPM. PFC enrollees experienced a nearly 50% reduction in the average number of inpatient days per month, from 4.2 to 2.3. Average length of stay per hospitalization dropped from an average of 16.7 days before enrollment to 6.5 days while in the program. Through the provision of home-based therapeutic services, 24/7 access to medical advice, and enhanced, personally tailored care coordination, PFC demonstrated an effective way to reduce costs for children with life-limiting conditions by moving from costly inpatient care to more coordinated and less expensive outpatient care. PFC's home-based care strategy is a cost-effective model for pediatric palliative care elsewhere. Copyright © 2016 American Academy of Hospice and Palliative Medicine. Published by Elsevier Inc.

New Mexico is a relatively poor and rural state which has sometimes struggled to achieve and maintain its childhood immunization rates. We evaluated New Mexico's immunization rates between 1996 and 2006. Specifically, we examined the increase in immunization rates between 2002 and 2004, and how this increase may have been associated with Medicaid enrollment levels, as opposed to changes in government policies concerning immunization practices.This study examines trends in childhood immunization coverage rates relative to Medicaid enrollment among those receiving Temporary Assistance for Needy Families (TANF in New Mexico. Information on health policy changes and immunization coverage was obtained from state governmental sources and the National Immunization Survey. We found statistically significant correlations varying from 0.86 to 0.93 between immunization rates and Medicaid enrollment.New Mexico's improvement and subsequent deterioration in immunization rates corresponded with changing Medicaid coverage, rather than the state's efforts to change immunization practices. Maintaining high Medicaid enrollment levels may be important for achieving high childhood immunization levels.

Automata and concurrency

Energy Technology Data Exchange (ETDEWEB)

Priese, L

1983-07-01

The author presents a precise notion of a realization (or simulation) of one concurrent system by another, and studies the relations of modular concurrent systems and non-persistent (i.e. With conflicts) concurrent systems in an automata theoretical style. He introduces a conception of realization that obeys three requirements: it allows for proper hierarchies in certain classes of concurrent systems; it allows for normal-form theorems, and the standard constructions of the literature remain realizations in formal concept; and it clarifies some counterintuitive examples. Further, although this realization conception is developed to translate the computational aspects of concurrent systems, it also gives a formal tool for the handling of synchronization problems. 38 references.

Channels as Objects in Concurrent Object-Oriented Programming

Directory of Open Access Journals (Sweden)

Joana Campos

2011-10-01

Full Text Available There is often a sort of a protocol associated to each class, stating when and how certain methods should be called. Given that this protocol is, if at all, described in the documentation accompanying the class, current mainstream object-oriented languages cannot provide for the verification of client code adherence against the sought class behaviour. We have defined a class-based concurrent object-oriented language that formalises such protocols in the form of usage types. Usage types are attached to class definitions, allowing for the specification of (1 the available methods, (2 the tests clients must perform on the result of methods, and (3 the object status - linear or shared - all of which depend on the object's state. Our work extends the recent approach on modular session types by eliminating channel operations, and defining the method call as the single communication primitive in both sequential and concurrent settings. In contrast to previous works, we define a single category for objects, instead of distinct categories for linear and for shared objects, and let linear objects evolve into shared ones. We introduce a standard sync qualifier to prevent thread interference in certain operations on shared objects. We formalise the language syntax, the operational semantics, and a type system that enforces by static typing that methods are called only when available, and by a single client if so specified in the usage type. We illustrate the language via a complete example.

To verify the concurrent validity and interobserver reliability of the Alberta Infant Motor Scale (AIMS) in premature infants followed-up at the outpatient clinic of Instituto Fernandes Figueira, Fundação Oswaldo Cruz (IFF/Fiocruz), in Rio de Janeiro, Brazil. A total of 88 premature infants were enrolled at the follow-up clinic at IFF/Fiocruz, between February and December of 2006. For the concurrent validity study, 46 infants were assessed at either 6 (n = 26) or 12 (n = 20) months' corrected age using the AIMS and the second edition of the Bayley Scales of Infant Development, by two different observers, and applying Pearson's correlation coefficient to analyze the results. For the reliability study, 42 infants between 0 and 18 months were assessed using the Alberta Infant Motor Scale, by two different observers and the results analyzed using the intraclass correlation coefficient. The concurrent validity study found a high level of correlation between the two scales (r = 0.95) and one that was statistically significant (p system.

Modeling land use and cover change: Predicting re-enrollment in the Conservation Reserve Program using GIS and data mining procedures

Science.gov (United States)

Shcherbaniuk, Mykola Vasylyovych

In this research, the concept of the CRP lands being re-enrolled or returned to crop production was considered as a part of a larger conceptual domain of land use and cover change (LUCC). The aim of the study was to develop models for predicting the probability of farmers' re-enrollment in the Conservation Reserve Program (CRP) in the Cache River Watershed, in Southern Illinois. The results of these analyses showed that the probability of the CRP re-enrollment is a function of a number of factors including both the economic incentives to farmers as well as the spatial and non-spatial characteristics of the farms and the CRP land parcels. Both logistical regressions and decision tree models confirmed the importance of seven individual variables. It was found that the probability of CRP re-enrollment was higher for parcels located closer to a stream, the national forest, a road and a town. Also higher re-enrollment was indicated for predominant farm location adjacent to the national forest and within a floodplain and on dry soils, higher proportion of farmland in pasture and higher elevation and population density. Alternatively, the probability of re-enrollment was found to be lower closer to an interstate highway, predominant farm location adjacent to the national refuge and higher proportion of farmland in row crops. The probability of CRP re-enrollment was found to be higher at higher CRP rental rates, lower commodity prices, lower cropland acreage, and lower proportion of farmland in cropland. For two additional important determinants, the probability of re-enrollment was found to be higher for lower proportion of cropland enrolled in CRP and in cases where the farmer was both the owner and operator. Overall, the results of this study indicate that the spatial heterogeneity of farms and land parcels (as accounted by spatial variables that were found to be relevant) should be taken into account while malting the plans for the CRP re-enrollment for the 2007 farm

2013-01-01

This study investigated the maximum tolerated dose (MTD) of S-1 with concurrent radiotherapy in patients with head and neck cancer, based on the frequency of dose-limiting toxicities (DLT). S-1 was administered orally at escalating doses from 40 mg/m 2 b.i.d. on the days of delivering radiotherapy, which was given at a total dose of 64-70 Gy in 32-35 fractions over 6-7 weeks. A total of 12 patients (3 patients at 40 mg/m 2 , 6 patients at 60 mg/m 2 , and 3 patients at 80 mg/m 2 ) were enrolled in this trial. At the dose of 80 mg/m 2 , two of the three patients developed DLT (Grade 3 anorexia and rhabdomyolysis) due to S-1, so the MTD was determined to be 80 mg/m 2 . Among the 12 enrolled patients, 9 (75%) showed a complete response and 3 (25%) showed a partial response. The overall response rate was 100%. The recommended dose of S-1 with concurrent radiotherapy is 60 mg/m 2 . (author)

2016-01-01

Women in sub-Saharan Africa continue to be at greater risk for HIV acquisition than men. Concurrency, viz. multiple sexual partnerships that overlap over time, has been studied as a possible risk factor for HIV transmission. The aim of this study was to identify predictors of perceived male partner concurrency among sexually active, HIV negative women. Socio-demographic and behavioural data from women enrolled in a biomedical HIV prevention clinical trial were assessed in relation to perceived male partner concurrency using the Chi squared test. Univariate and multivariate logistic regression was performed to assess the independent predictors of perceived male partner concurrency. Kaplan-Meier survival estimates were obtained for HIV and STI incidence in relation to male partner concurrency. A Cox Proportional Hazards model was used to assess the association between perceived male partner concurrency and HIV and STI incidence. The results revealed that 29 % of women reported their male partners to be in concurrent sexual relationships, 22 % reported partners that were not engaging in concurrency, whilst 49 % reported not knowing their partners concurrency status. Older women, having never married, experiencing economic abuse, and women reporting individual concurrency, were found to be significant predictors of perceived male partner concurrency in the studied population. Perceived male partner concurrency was not found to be a significantly associated with incident HIV and STI infections in this analysis. The study provides insight into predictors of perceived male partner concurrency among women at high risk for STI and HIV acquisition. These results may inform the design of behavioural and biomedical interventions, to address the role of multiple sexual partnerships in HIV prevention.

Full Text Available History and Objective: Obesity is one of the health risks factors, and aerobic exercise is one of the means to prevent and control obesity. The research was designed to compare methods of resistance, aerobic, and concurrent exercises on resistin and C-reactive protein (CRP serum level of overweight and obese women. Research Methodology: In this semi-experimental research, 36 voluntary overweight or obese women were randomly assigned into three groups (n = 12 of aerobic, resistance, and concurrent exercise programs. The training included 8 weeks of exercise performed with 55%–75% of 1-repetition maximum weight lifting. The aerobic exercise was performed at 55%–75% of maximum oxygen consumption and concurrent training included both programs for 3 days/week. The resistin and CRP serum level of the participant was measured 48 h before the start and again 48 h after the termination of the exercise protocol. The statistical analysis was performed on data using SPSS 22.0 (Chicago, USA. One-way analysis of variance and paired t-test was employed to test the hypothesis at significance level set to 0.05. Results: The result indicated that exercise program significantly decreased CRP level of blood serum (P 0.05. Discussion: Aerobic exercise regardless of types has a beneficiary effect on CPR, but resistin level needs different types of exercise to change in overweight and obese women. Conclusion: Some aerobic exercises are beneficiary for overweight and obese women health.

To investigate the prevalence and correlates of concurrent (overlapping) sexual partnerships among female sex workers (FSWs) and their non-commercial male partners in two Mexico-US border cities. A cross-sectional survey of FSWs and their non-commercial male partners was conducted in Tijuana and Ciudad Juárez, Mexico (2010-2011). Eligible FSWs and verified non-commercial partners were aged ≥18 years; FSWs had ever used hard drugs (lifetime) and recently exchanged sex for money, drugs or other goods (past month). Participants underwent baseline questionnaires obtaining dates of sex and condom use with ≤5 other recurring partners, including FSWs' regular clients. These dates were compared with dates of sex with enrolled study partners to determine overlap (ie, 'recurring' concurrency). Bivariate probit regression identified recurring concurrency correlates. Among 428 individuals (214 couples), past-year recurring concurrency prevalence was 16% and was higher among women than their non-commercial male partners (26% vs 6%). In 10 couples (5%), both partners reported recurring concurrency. The majority of couples (64%) always had unprotected sex, and most of the individuals (70%) with recurring concurrency 'sometimes' or 'never' used condoms with their concurrent partners. Recurring concurrency was positively associated with FSWs' income, men's caballerismo (a form of traditional masculinity) and men's belief that their FSW partners had sexually transmitted infections (STIs). Recurring concurrency, representing sustained periods of overlapping partnerships in which unprotected sex was common, should be addressed by couple-based STI prevention interventions.

Full Text Available This cross-sectional study checks specific self-care activities of patients with diabetes mellitus enrolled in a self-monitoring blood glucose program from August to December 2012 in two Primary Health Care units in the interior of São Paulo, Brazil. The sample was composed of 74 female and male individuals, aged 18 years old or older. The Summary of Diabetes Self-Care Activities Questionnaire was used. It contains six dimensions: general diet, specific diet, physical activity, blood glucose monitoring, foot care, medication usage, plus three items about smoking. Eight out of the 15 self-care activities were within desirable levels, namely: healthy diet, not eating sweets, blood glucose testing and as frequently as recommended, drying between toes after washing feet, and taking medications (three items. The results enabled the identification of gaps in specific self-care activities among patients with diabetes mellitus.

Characterizing Distributed Concurrent Engineering Teams: A Descriptive Framework for Aerospace Concurrent Engineering Design Teams

Science.gov (United States)

Chattopadhyay, Debarati; Hihn, Jairus; Warfield, Keith

2011-01-01

As aerospace missions grow larger and more technically complex in the face of ever tighter budgets, it will become increasingly important to use concurrent engineering methods in the development of early conceptual designs because of their ability to facilitate rapid assessments and trades in a cost-efficient manner. To successfully accomplish these complex missions with limited funding, it is also essential to effectively leverage the strengths of individuals and teams across government, industry, academia, and international agencies by increased cooperation between organizations. As a result, the existing concurrent engineering teams will need to increasingly engage in distributed collaborative concurrent design. This paper is an extension of a recent white paper written by the Concurrent Engineering Working Group, which details the unique challenges of distributed collaborative concurrent engineering. This paper includes a short history of aerospace concurrent engineering, and defines the terms 'concurrent', 'collaborative' and 'distributed' in the context of aerospace concurrent engineering. In addition, a model for the levels of complexity of concurrent engineering teams is presented to provide a way to conceptualize information and data flow within these types of teams.

Purpose: To determine the maximum tolerated dose of radiation therapy (RT) given in an accelerated fashion with concurrent chemotherapy using intensity modulated RT. Methods and Materials: Patients with locally advanced lung cancer (non-small cell and small cell) with good performance status and minimal weight loss received concurrent cisplatin and etoposide with RT. Intensity modulated RT with daily image guidance was used to facilitate esophageal avoidance and delivered using 6 fractions per week (twice daily on Fridays with a 6-hour interval). The dose was escalated from 58 Gy to a planned maximum dose of 74 Gy in 4 Gy increments in a standard 3 + 3 trial design. Dose-limiting toxicity (DLT) was defined as acute grade 3-5 nonhematologic toxicity attributed to RT. Results: A total of 24 patients were enrolled, filling all dose cohorts, all completing RT and chemotherapy as prescribed. Dose-limiting toxicity occurred in 1 patient at 58 Gy (grade 3 esophagitis) and 1 patient at 70 Gy (grade 3 esophageal fistula). Both patients with DLTs had large tumors (12 cm and 10 cm, respectively) adjacent to the esophagus. Three additional patients were enrolled at both dose cohorts without further DLT. In the final 74-Gy cohort, no DLTs were observed (0 of 6). Conclusions: Dose escalation and acceleration to 74 Gy with intensity modulated RT and concurrent chemotherapy was tolerable, with a low rate of grade ≥3 acute esophageal reactions.

In Manitoba, Canada, school-based clinics providing sexual and reproductive health services for adolescents have been implemented to address high rates of sexually transmitted infections (STIs) and pregnancies. The objectives of this population-based study were to compare pregnancy and STI rates between adolescents enrolled in schools with school-based clinics, those in schools without clinics, and those not enrolled in school. Data were from the PATHS Data Resource held in the Population Health Research Data Repository housed at the Manitoba Centre for Health Policy. Adolescents aged 14 to 19 between 2003 and 2009 were included in the study. Annualized rates of pregnancies and positive STI tests were estimated and Poisson regression models were used to test for differences in rates amongst the three groups. As a proportion, pregnancies among non-enrolled female adolescents accounted for 55 % of all pregnancies in this age group during the study period. Pregnancy rates were 2-3 times as high among non-enrolled female adolescents. Compared to adolescents enrolled in schools without school-based clinics, age-adjusted STI rates were 3.5 times (p pregnancies and STIs were observed among non-enrolled adolescents. Although provision of reproductive and health services to in-school adolescents should remain a priority, program planning and design should consider optimal strategies to engage out of school youth.

Selective enrollment in Disease Management Programs for coronary heart disease in Germany - An analysis based on cross-sectional survey and administrative claims data.

Röttger, Julia; Blümel, Miriam; Busse, Reinhard

2017-04-04

In 2002, Disease Management Programs (DMPs) were introduced within the German healthcare system with the aim to increase the quality of chronic disease care. Due to the enrollment procedures, it can be assumed a) that only certain patients actively decide to enroll in a DMP and/or b) that only certain patients get the recommendation for DMP enrollment from their physician. How strong this assumed effect of self- and/or professional selection is, is still unclear. We used data from a cross-sectional postal-survey linked on individual level with administrative claims data from a German sickness fund. The sample consisted of individuals suffering from coronary heart disease (CHD) who i) were either enrolled in the respective DMP or ii) fulfilled the disease related criteria for enrollment but were not enrolled. We applied multivariate logistic regression analyses to assess factors on patient level associated with DMP enrollment. We included 7070 individuals in our analyses. Male sex, higher age and receiving old age pension, a higher Charlson Score and a diagnosis of type 2 diabetes increased the odds for DMP-CHD enrollment significantly. Individuals with a diagnosed myocardial infarction (MI) were also more likely to be enrolled in the DMP-CHD. We found a significant interaction effect for MI and sex, indicating that the association between MI and DMP enrollment is stronger for women than for men. DMP-enrollees and non-enrollees differ in various factors. Studies analyzing the effectiveness of DMP-CHD should carefully take into account these group differences. Furthermore, the results suggest that the DMP-CHD assessed reaches men better than women.

Introduction Recurrent joint hemarthroses due to hemophilia (Factor VIII and Factor IX deficiency) often lead to invasive orthopedic interventions to decrease frequency of bleeding and/or to alleviate pain associated with end-stage hemophilic arthropathy. Aim Identify trends in invasive orthopedic interventions among people with hemophilia who were enrolled in the Universal Data Collection (UDC) program during the period 2000–2010. Methods Data were collected from 130 hemophilia treatment centers in the United States annually during the period 2000–2010, in collaboration with the Centers for Disease Control and Prevention (CDC). The number of visits in which an invasive orthopedic intervention was reported was expressed as a proportion of the total visits in each year of the program. Invasive orthopedic interventions consisted of arthroplasty, arthrodesis, and synovectomy. Joints included in this study were the shoulder, elbow, hip, knee, and ankle. Results A 5.6% decrease in all invasive orthopedic interventions in all joints of people with hemophilia enrolled in the UDC program over the 11-year study period was observed. Conclusions These data reflect a declining trend in invasive orthopedic interventions in people with hemophilia. Further research is needed to understand the characteristics that may influence invasive orthopedic interventions. PMID:27030396

Kerr, Christopher W; Donohue, Kathleen A; Tangeman, John C; Serehali, Amin M; Knodel, Sarah M; Grant, Pei C; Luczkiewicz, Debra L; Mylotte, Kathleen; Marien, Melanie J

2014-12-01

In the United States, 5% of the population is responsible for nearly half of all health care expenditures, with a large concentration of spending driven by individuals with expensive chronic conditions in their last year of life. Outpatient palliative care under the Medicare Hospice Benefit excludes a large proportion of the chronically ill and there is widespread recognition that innovative strategies must be developed to meet the needs of the seriously ill while reducing costs. This study aimed to evaluate the impact of a home-based palliative care program, implemented through a hospice-private payer partnership, on health care costs and utilization. This was a prospective, observational database study where insurance enrollment and claims data were analyzed. The study population consisted of Home Connections (HC) program patients enrolled between January 1, 2010 and December 31, 2012 who subsequently expired (n=149) and who were also Independent Health members. A control group (n=537) was derived using propensity-score matching. The primary outcome variable was overall costs within the last year of life. Costs were also examined at six months, three months, one month, and two weeks. Inpatient, outpatient, ancillary, professional, and pharmacy costs were compared between the two groups. Medical service utilization and hospice enrollment and length of stay were also evaluated. Cost savings were apparent in the last three months of life—$6,804 per member per month (PMPM) cost for palliative care participants versus $10,712 for usual care. During the last two weeks of life, total allowed PMPM was $6,674 versus $13,846 for usual care. Enhanced hospice entry (70% versus 25%) and longer length of stay in hospice (median 34 versus 9 days) were observed. Palliative care programs partnered with community hospice providers may achieve cost savings while helping provide care across the continuum.

Pre-Enrollment Reimbursement Patterns of Medicare Beneficiaries Enrolled in “At-Risk” HMOs

Science.gov (United States)

Eggers, Paul W.; Prihoda, Ronald

1982-01-01

The Health Care Financing Administration (HCFA) has initiated several demonstration projects to encourage HMOs to participate in the Medicare program under a risk mechanism. These demonstrations are designed to test innovative marketing techniques, benefit packages, and reimbursement levels. HCFA's current method for prospective payments to HMOs is based on the Adjusted Average Per Capita Cost (AAPCC). An important issue in prospective reimbursement is the extent to which the AAPCC adequately reflects the risk factors which arise out of the selection process of Medicare beneficiaries into HMOs. This study examines the pre-enrollment reimbursement experience of Medicare beneficiaries who enrolled in the demonstration HMOs to determine whether or not a non-random selection process took place. The three demonstration HMOs included in the study are the Fallon Community Health Plan, the Greater Marshfield Community Health Plan, and the Kaiser-Permanente medical program of Portland, Oregon. The study includes 18,085 aged Medicare beneficiaries who had enrolled in the three plans as of April, 1981. We included comparison groups consisting of a 5 percent random sample of aged Medicare beneficiaries (N = 11,240) living in the same geographic areas as the control groups. The study compares the groups by total Medicare reimbursements for the years 1976 through 1979. Adjustments were made for AAPCC factor differences in the groups (age, sex, institutional status, and welfare status). In two of the HMO areas there was evidence of a selection process among the HMOs enrollees. Enrollees in the Fallon and Kaiser health plans were found to have had 20 percent lower Medicare reimbursements than their respective comparison groups in the four years prior to enrollment. This effect was strongest for inpatient services, but a significant difference also existed for use of physician and outpatient services. In the Marshfield HMO there was no statistically significant difference in pre-enrollment

Examining the Factors Associated with Paid Employment of Clients Enrolled in First Episode of Psychosis Programs

Directory of Open Access Journals (Sweden)

Carolyn S. Dewa

2012-01-01

Full Text Available Schizophrenia is one of the most debilitating mental disorders. For a significant portion of individuals who suffer from this disorder, onset occurs in young adulthood, arresting important social and educational development that is necessary for future successful labor force participation. The purpose of this paper is to contribute to the literature about clients enrolled in first episode psychosis programs and psychosocial outcomes by examining the factors associated with paid employment among young adults who have experienced their first psychotic episodes. In this paper, we consider the association of socioeconomic factors to employment. Our results suggest that in addition to treatment, socioeconomic factors such as receipt of public disability benefits and educational attainment are associated with employment status. These results can help to inform future directions for the enhancement of psychosocial programs in FEP models to promote paid employment.

Concurrency at work with Go

CERN Document Server

CERN. Geneva

2017-01-01

High Energy and Nuclear Physics (HENP) libraries are now required to be increasingly multi-thread-safe, if not multi-thread-friendly and multi-threaded. This is usually done using the new constructs and library components offered by the C++11 and C++14 standards. These components are however quite low-level (threads, mutexes, locks, ...) and hard to use and compose, or easy to misuse. However, Go -- a somewhat new language -- provides a set of better building blocks for tackling concurrency: goroutines and channels. This language is now used by the cloud industry at large; docker/moby, rkt, Kubernetes, OpenShift, etc... are obvious flagships for Go. It is also used in other interesting places like SpaceX's telemetry monitoring system and in the New York Times', YouTube's or Disney's content delivery infrastructures. In this talk, we will describe the building blocks of Go and see how they are combined to easily create concurrent programs that grow with grace, are fast to compile and deploy, but also easy to...

Although logically available, applications may not exploit enough instantaneous communication concurrency to maximize hardware utilization on HPC systems. This is exacerbated in hybrid programming models such as SPMD+OpenMP. We present the design of a "multi-threaded" runtime able to transparently increase the instantaneous network concurrency and to provide near saturation bandwidth, independent of the application configuration and dynamic behavior. The runtime forwards communication requests from application level tasks to multiple communication servers. Our techniques alleviate the need for spatial and temporal application level message concurrency optimizations. Experimental results show improved message throughput and bandwidth by as much as 150% for 4KB bytes messages on InfiniBand and by as much as 120% for 4KB byte messages on Cray Aries. For more complex operations such as all-to-all collectives, we observe as much as 30% speedup. This translates into 23% speedup on 12,288 cores for a NAS FT implemented using FFTW. We also observe as much as 76% speedup on 1,500 cores for an already optimized UPC+OpenMP geometric multigrid application using hybrid parallelism.

Concurrence can measure the entanglement property of a system. If the channel is a pure state, positive concurrence state can afford the good performance in the teleportation process. If the channel ia a mixed state, positive concurrence state cannot assure the good performance in the teleportation. The conditions of the positive concurrence and the quantum teleportation in the Heisenberg spin ring is derived.

The GLobal Integrated Design Environment (GLIDE) is a client-server software application purpose-built to mitigate issues associated with real time data sharing in concurrent engineering environments and to facilitate discipline-to-discipline interaction between multiple engineers and researchers. GLIDE is implemented in multiple programming languages utilizing standardized web protocols to enable secure parameter data sharing between engineers and researchers across the Internet in closed and/or widely distributed working environments. A well defined, HyperText Transfer Protocol (HTTP) based Application Programming Interface (API) to the GLIDE client/server environment enables users to interact with GLIDE, and each other, within common and familiar tools. One such common tool, Microsoft Excel (Microsoft Corporation), paired with its add-in API for GLIDE, is discussed in this paper. The top-level examples given demonstrate how this interface improves the efficiency of the design process of a concurrent engineering study while reducing potential errors associated with manually sharing information between study participants.

developing a student's sense of capability, purpose, resourcefulness, identity and connectedness (five-senses of success) are key factors that may be important in predicting student satisfaction and progression within their university program. the study aimed to examine the expectations and experiences of second and third year midwifery students enroled in a Bachelor of Midwifery program and identify barriers and enablers to success. a descriptive exploratory qualitative design was used. Fifty-six students enroled in either year 2 or 3 of the Bachelor of Midwifery program in SE Queensland participated in an anonymous survey using open-ended questions. In addition, 16 students participated in two year-level focus groups. Template analysis, using the Five Senses Framework, was used to analyse the data set. early exposure to 'hands on' clinical midwifery practice as well as continuity of care experiences provided students with an opportunity to link theory to practice and increased their perception of capability as they transitioned through the program. Students' sense of identity, purpose, resourcefulness, and capability was strongly influenced by the programs embedded meta-values, including a 'woman centred' approach. In addition, a student's ability to form strong positive relationships with women, peers, lecturers and supportive clinicians was central to developing connections and ultimately a sense of success. A sense of connection not only fostered an ongoing belief that challenges could be overcome but that students themselves could initiate or influence change. the five senses framework provided a useful lens through which to analyse the student experience. Key factors to student satisfaction and retention within a Bachelor of Midwifery program include: a clearly articulated midwifery philosophy, strategies to promote student connectedness including the use of social media, and further development of clinicians' skills in preceptorship, clinical teaching and

2009-01-01

Using focus group data, this article discusses the use of social marketing principles to enhance enrollment in the Cash and Counseling Demonstration and Evaluation (CCDE). Focus groups were conducted in person and by conference call in two CCDE states, Arkansas and Florida. In Florida, Department of Elder Affairs and Developmental Services Program (DS) staff participated in seven focus groups. In Arkansas, four focus groups were conducted with professionals likely to come into contact with Medicaid consumers who are eligible for Arkansas' cash option program. Focus group transcripts were coded according to the project research questions. Several important lessons emerged including the importance of(a) conducting process evaluation activities, such as the social marketing focus groups, early during program implementation; (b) using multiple approaches and contacts to inform potential consumers and their families about a new, complex program; (c) carefully selecting and training personnel to conduct outreach and enrollment activities; and (d) developing specific messages to include in marketing the cash option. Using social marketing principles to examine CCDE enrollment has provided important information to enhance this program.

One possible factor is the amount of concurrent cognitive training received during the training program. In this pilot study, we recruited 24 elderly adults with or without concurrent cognitive stimulations to attend a memory-training program. Findings suggested that elderly people without concurrent cognitive stimulation could benefit from a memory-training program in the form of improved initiation and memory functioning. Self-rated quality of life measure also showed improvements alongside the cognitive benefits. Elderly people with regular concurrent cognitive stimulation, on the other hand, seemed to plateau in their level of performance and did not show any significant change. Our preliminary findings suggested nonlinear concurrent cognitive stimulation in the elderly.Keywords: memory training, cognitive training, dementia, Chinese, elderly

Randomized controlled trials have demonstrated the efficacy of nurse-led transitional care programs to reduce readmission rates for patients with heart failure; the effectiveness of these programs in real-world health care systems is less well understood. We performed a prospective study with concurrent controls to test an advanced practice nurse-led transitional care program for patients with heart failure who were 65 years or older and were discharged from Baylor Medical Center Garland (BMCG) from August 24, 2009, through April 30, 2010. We compared the effect of the program on 30-day (from discharge) all-cause readmission rate, length of stay, and 60-day (from admission) direct cost for BMCG with that of other hospitals within the Baylor Health Care System. We also performed a budget impact analysis using costs and reimbursement experience from the intervention. The intervention significantly reduced adjusted 30-day readmission rates to BMCG by 48% during the postintervention period, which was better than the secular reductions seen at all other facilities in the system. The intervention had little effect on length of stay or total 60-day direct costs for BMCG. Under the current payment system, the intervention reduced the hospital financial contribution margin on average $227 for each Medicare patient with heart failure. Preliminary results suggest that transitional care programs reduce 30-day readmission rates for patients with heart failure. This underscores the potential of the intervention to be effective in a real-world setting, but payment reform may be required for the intervention to be financially sustainable by hospitals.

Full Text Available BACKGROUND: In Mozambique during 2004-2007 numbers of adult patients (≥15 years old enrolled on antiretroviral therapy (ART increased about 16-fold, from 60 kg, WHO stage IV (AHR 1.7; 95% CI, 1.3-2.4, reference group WHO stage I/II, lack of co-trimoxazole prescription (AHR 1.4; 95% CI, 1.0-1.8, and later calendar year of ART initiation (AHR 1.5; 95% CI, 1.2-1.8. Rates of immunologic treatment failure and regimen-switch were 14.0 and 0.6 events per 100-patient years, respectively. CONCLUSIONS: ART initiation at earlier disease stages and scale-up of co-trimoxazole among ART patients could improve outcomes. Research to determine reasons for low regimen-switch rates and increasing rates of attrition during program expansion is needed.

Multi-versioned database systems have the potential to significantly increase the amount of concurrency in transaction processing because they can avoid read-write conflicts. Unfortunately, the increase in concurrency usually comes at the cost of transaction serializability. If a database user requests full serializability, modern multi-versioned systems significantly constrain read-write concurrency among conflicting transactions and employ expensive synchronization patterns in their design....

Intergenerational enrollment and expenditure changes in Medicaid: trends from 1991 to 2005

Directory of Open Access Journals (Sweden)

Patrick Stephen W

2012-09-01

Full Text Available Abstract Background From its inception, Medicaid was aimed at providing insurance coverage for low income children, elderly, and disabled. Since this time, children have become a smaller proportion of the US population and Medicaid has expanded to additional eligibility groups. We sought to evaluate relative growth in spending in the Medicaid program between children and adults from 1991-2005. We hypothesize that this shifting demographic will result in fewer resources being allocated to children in the Medicaid program. Methods We utilized retrospective enrollment and expenditure data for children, adults and the elderly from 1991 to 2005 for both Medicaid and Children’s Health Insurance Program Medicaid expansion programs. Data were obtained from the Centers for Medicare and Medicaid Services using their Medicaid Statistical Information System. Results From 1991 to 2005, the number of enrollees increased by 83% to 58.7 million. This includes increases of 33% for children, 100% for adults and 50% for the elderly. Concurrently, total expenditures nationwide rose 150% to $273 billion. Expenditures for children increased from $23.4 to $65.7 billion, adults from $46.2 to $123.6 billion, and elderly from $39.2 to $71.3 billion. From 1999 to 2005, Medicaid spending on long-term care increased by 31% to $84.3 billion. Expenditures on the disabled grew by 61% to $119 billion. In total, the disabled account for 43% and long-term care 31%, of the total Medicaid budget. Conclusion Our study did not find an absolute decrease in the overall resources being directed toward children. However, increased spending on adults on a per-capita and absolute basis, particularly disabled adults, is responsible for much of the growth in spending over the past 15 years. Medicaid expenditures have grown faster than inflation and overall national health expenditures. A national strategy is needed to ensure adequate coverage for Medicaid recipients while dealing with the

Purpose: To determine the safety, efficacy, and tolerability of biweekly gemcitabine with concurrent radiotherapy (RT) for resected and locally advanced (LA) pancreatic cancer. Methods and Materials: Eligible patients had either LA or resected pancreatic cancer. Between March 1999 and July 2001, 63 patients (31 with LA and 32 with resected disease) were treated. Of the 63 patients, 28 were enrolled in a Phase I study of increasing radiation doses (35 Gy [n = 7], 43.75 Gy [n = 11], and 52.5 Gy [n = 10] given within 4, 5, or 6 weeks, respectively, in 1.75-Gy fractions) concurrently with 40 mg/m 2 gemcitabine biweekly. Subsequently, 35 were enrolled in a Phase II study with the addition of induction gemcitabine 1000 mg/m 2 within 7 or 8 weeks to concurrent biweekly gemcitabine (40 mg/m 2 ) and 52.5 Gy RT within 6 weeks. Results: In the LA population, the best response observed was a complete response in 1, partial response in 3, stable disease in 10, and progressive disease in 17. In the phase II trial, gemcitabine plus RT was not delivered to 8 patients because of progression with induction gemcitabine alone (n = 5) or by patient request (n = 3). On intent-to-treat analysis, the median survival in the LA patients was 13.9 months and the 2-year survival rate was 16.1%. In the resected population, the median progression-free survival was 8.3 months, the median survival was 18.4 months, and the 2- and 5-year survival rate was 36% and 19.4%, respectively. The treatment was well tolerated; the median gemcitabine dose intensity was 96% of the planned dose in the neoadjuvant and concurrent portions of the Phase II study. No treatment-related deaths occurred. Conclusion: Biweekly gemcitabine (40 mg/m 2 ) concurrently with RT (52.5 Gy in 30 fractions of 1.75 Gy) with or without induction gemcitabine is safe and tolerable and shows efficacy in patients with LA and resected pancreatic cancer

Measuring coherence with entanglement concurrence

Science.gov (United States)

Qi, Xianfei; Gao, Ting; Yan, Fengli

2017-07-01

Quantum coherence is a fundamental manifestation of the quantum superposition principle. Recently, Baumgratz et al (2014 Phys. Rev. Lett. 113 140401) presented a rigorous framework to quantify coherence from the view of theory of physical resource. Here we propose a new valid quantum coherence measure which is a convex roof measure, for a quantum system of arbitrary dimension, essentially using the generalized Gell-Mann matrices. Rigorous proof shows that the proposed coherence measure, coherence concurrence, fulfills all the requirements dictated by the resource theory of quantum coherence measures. Moreover, strong links between the resource frameworks of coherence concurrence and entanglement concurrence is derived, which shows that any degree of coherence with respect to some reference basis can be converted to entanglement via incoherent operations. Our work provides a clear quantitative and operational connection between coherence and entanglement based on two kinds of concurrence. This new coherence measure, coherence concurrence, may also be beneficial to the study of quantum coherence.

Quantify entanglement by concurrence hierarchy

OpenAIRE

Fan, Heng; Matsumoto, Keiji; Imai, Hiroshi

2002-01-01

We define the concurrence hierarchy as d-1 independent invariants under local unitary transformations in d-level quantum system. The first one is the original concurrence defined by Wootters et al in 2-level quantum system and generalized to d-level pure quantum states case. We propose to use this concurrence hierarchy as measurement of entanglement. This measurement does not increase under local quantum operations and classical communication.

Concurrent Models for Object Execution

In previous work we developed a framework of computational models for the concurrent execution of functions on different levels of abstraction. It shows that the traditional sequential execution of function is just a possible implementation of an abstract computational model that allows for the concurrent execution of functions. We use this framework as base for the development of abstract computational models that allow for the concurrent execution of objects.

To determine if patterns of predominant asthma disease activity are more closely related than baseline asthma severity to measures of morbidity (acute asthma attack, emergency room visit/hospitalization, missed school days, and/or steroid burst). Retrospective analysis was performed for inner-city Los Angeles asthmatic children (3 to 18 years of age) during their first year of enrollment in an asthma-specific disease management program. All measures of morbidity were more closely related to patterns of predominant disease activity than baseline severity. We conclude that patterns of predominant disease activity are a more significant predictor of asthma morbidity than is baseline severity.

Introduction We assess the relationship between race and orthodontic service utilization for Medicaid-enrolled children. Methods This cross-sectional study focused on 570,364 Washington Medicaid-enrolled children ages 6-19 years. The main predictor variable was self-reported race (White versus non-White). The outcome variable was orthodontic service utilization, defined as children who were pre-authorized for orthodontic treatment by Medicaid in 2012 and subsequently received orthodontic records and initiated treatment. Logistic regression models were used to test the hypothesis that non-Whites would be less likely to utilize orthodontic care than Whites. Results A total of 8,223 children were approved by Medicaid for orthodontic treatment and 7,313 received records and initiated treatment. Non-Whites were significantly more likely to utilize orthodontic care than Whites (Odds Ratio [OR]=1.18; 95% confidence interval [CI]=1.02, 1.36; p=.031). Hispanic non-White children were more likely to utilize orthodontic care than non-Hispanic White children (OR=1.42; 95% CI=1.18, 1.70; porthodontic care than White children. The Washington Medicaid program demonstrates a potential model for addressing racial disparities in orthodontic service utilization. Future research should identify mechanisms underlying these findings and continue to monitor orthodontic service utilization for minority children in Medicaid. PMID:27021456

We employed a cluster randomized trial design to measure the impact of a school based water, sanitation, and hygiene (WASH) improvement on pupil enrollment and on gender parity in enrollment, in primary schools in Nyanza Province, Kenya (2007-2009). Among schools with poor water access during the dry season, those that received a water supply, hygiene promotion and water treatment (HP&WT) and sanitation improvement, demonstrated increased enrollment (β=0.091 [0.009, 0.173] p=0.03), which translates to 26 additional pupils per school on average. The proportion of girls enrolled in school also increased by 4% (prevalence ratio (PR)=1.04 [1.00, 1.07] p=0.02). Among schools with better baseline water access during the dry season (schools that didn't receive a water source), we found no evidence of increased enrollment in schools that received a HP&WT intervention (β=0.016 [-0.039, 0.072] p=0.56) or the HP&WT and sanitation intervention (β=0.027 [-0.028, 0.082]p=0.34), and there was no evidence of improved gender parity (PR=0.99 [0.96, 1.02] p=0.59, PR=1.00 [0.97, 1.02] p=0.75, respectively). Our findings suggest that increased school enrollment and improved gender parity may be influenced by a comprehensive WASH program that includes an improved water source; schools with poor water access during the dry season may benefit most from these interventions.

The Effect of Two Different Concurrent Training Programs on Strength and Power Gains in Highly-Trained Individuals

Petré, Henrik; Löfving, Pontus; Psilander, Niklas

2018-01-01

The effects of concurrent strength and endurance training have been well studied in untrained and moderately-trained individuals. However, studies examining these effects in individuals with a long history of resistance training (RT) are lacking. Additionally, few studies have examined how strength and power are affected when different types of endurance training are added to an RT protocol. The purpose of the present study was to compare the effects of concurrent training incorporating either low-volume, high-intensity interval training (HIIT, 8-24 Tabata intervals at ~150% of VO2max) or high-volume, medium-intensity continuous endurance training (CT, 40-80 min at 70% of VO2max), on the strength and power of highly-trained individuals. Sixteen highly-trained ice-hockey and rugby players were divided into two groups that underwent either CT (n = 8) or HIIT (n = 8) in parallel with RT (2-6 sets of heavy parallel squats, > 80% of 1RM) during a 6-week period (3 sessions/wk). Parallel squat performance improved after both RT + CT and RT + HIIT (12 ± 8% and 14 ± 10% respectively, p HIIT (4 ± 3%, p HIIT in athletes with a prior history of RT. This indicates that the volume and/or intensity of the endurance training does not influence the magnitude of strength improvements during short periods of concurrent training, at least for highly-trained individuals when the endurance training is performed after RT. However, since VO2max improved only after RT + HIIT and this is a time efficient protocol, we recommend this type of concurrent endurance training. Key points Lower body maximal strength is improved after concurrent strength and endurance training in highly trained individuals. The magnitude of this strength improvement is not influenced by the type of endurance training, i.e. HIIT or CT. HIIT improves VO2max and is more time efficient than CT. HIIT is recommended to athletes when concurrently training for strength and endurance. PMID:29769816

Nutritional strategies to support concurrent training.

2015-01-01

Concurrent training (the combination of endurance exercise to resistance training) is a common practice for athletes looking to maximise strength and endurance. Over 20 years ago, it was first observed that performing endurance exercise after resistance exercise could have detrimental effects on strength gains. At the cellular level, specific protein candidates have been suggested to mediate this training interference; however, at present, the physiological reason(s) behind the concurrent training effect remain largely unknown. Even less is known regarding the optimal nutritional strategies to support concurrent training and whether unique nutritional approaches are needed to support endurance and resistance exercise during concurrent training approaches. In this review, we will discuss the importance of protein supplementation for both endurance and resistance training adaptation and highlight additional nutritional strategies that may support concurrent training. Finally, we will attempt to synergise current understanding of the interaction between physiological responses and nutritional approaches into practical recommendations for concurrent training.

To assess the academic performance and experiences of local, international, and collaborative exchange students enrolled in a 4-year Australian bachelor of pharmacy degree program. Survey instruments exploring the demographics, background, and academic and cultural experiences of students during the program were administered in 2005 to students in all 4 years. Additionally, grades from each semester of the program for students (406 local, 70 international, 155 exchange) who graduated between 2002 and 2006 were analyzed retrospectively. The main differences found in the survey responses among the 3 groups were in students' motivations for choosing the degree program and school, with international and collaborative exchange students having put more thought into these decisions than local students. The average grades over the duration of the program were similar in all 3 demographic groups. However, local students slightly outperformed international students, particularly at the start of the year, whereas collaborative exchange students' grades mirrored those of local students during the 2 years prior to leaving their home country of Malaysia but more closely mirrored those of international students in the final 2 years after arriving on campus in Australia. Despite differences in academic backgrounds and culture, international and exchange students can perform well compared to local students in a bachelor of pharmacy program and were actually more satisfied than local students with the overall experience. Studying in a foreign country can negatively influence academic grades to a small extent and this is probably related to adjusting to the new environment.

We apply genuine multipartite concurrence to investigate entanglement properties of three Jaynes-Cummings systems. Three atoms are initially put in GHZ-like state and locally interact with three independent cavities, respectively. We present analytical concurrence expressions for various subsystems including three-atom, three-cavity and some atom-cavity mixed systems. We also examine the global system and illustrate the evolution of its concurrence. Except for the sudden death of entanglement, we find for some initial entanglement parameter θ , the concurrence of the global system may maintain unchanged in some time intervals.

Introduction Although the clinical consequences of homelessness are well described, less is known about the role for health care systems in improving clinical and social outcomes for the homeless. We described the national implementation of a “homeless medical home” initiative in the Veterans Health Administration (VHA) and correlated patient health outcomes with characteristics of high-performing sites. Methods We conducted an observational study of 33 VHA facilities with homeless medical homes and patient- aligned care teams that served more than 14,000 patients. We correlated site-specific health care performance data for the 3,543 homeless veterans enrolled in the program from October 2013 through March 2014, including those receiving ambulatory or acute health care services during the 6 months prior to enrollment in our study and 6 months post-enrollment with corresponding survey data on the Homeless Patient Aligned Care Team (H-PACT) program implementation. We defined high performance as high rates of ambulatory care and reduced use of acute care services. Results More than 96% of VHA patients enrolled in these programs were concurrently receiving VHA homeless services. Of the 33 sites studied, 82% provided hygiene care (on-site showers, hygiene kits, and laundry), 76% provided transportation, and 55% had an on-site clothes pantry; 42% had a food pantry and provided on-site meals or other food assistance. Six-month patterns of acute-care use pre-enrollment and post-enrollment for 3,543 consecutively enrolled patients showed a 19.0% reduction in emergency department use and a 34.7% reduction in hospitalizations. Three features were significantly associated with high performance: 1) higher staffing ratios than other sites, 1) integration of social supports and social services into clinical care, and 3) outreach to and integration with community agencies. Conclusion Integrating social determinants of health into clinical care can be effective for high

Note on specifying and verifying concurrent processes

Energy Technology Data Exchange (ETDEWEB)

Holenderski, L.

1984-02-28

To represent sequential processes, sets of finite sequences of symbols from a finite alphabet are used in this approach, alphabet symbols denote events occurring when a process is being executed, a sequence of symbols is a record of one execution of the process, and a set of such sequences represents the process itself by combining all its possible executions together. Although this model turned out adequate for specifying concurrent processes and allows proving their properties, there are two reasons, at least, why this note takes the same subject up again. First, by analogy to shuffle and its closure, which express parallel combination and parallel iteration of non-interacting processes, there is a need for a similar operation describing the behaviour of interaction processes. A new extension of shuffle is proposed as a generalization. The closure of this operation provides a tool for specification of parallelly iterated processes. Moreover, the closure makes mutually recursive specification unnecessary. Second, when this model was used to prove properties of concurrent computations, only flow-of-control schemes were considered (thus, only some general properties were proved). When applied to concrete programs using variables that have values, such schemes had to be interpreted. In contrast to such a schematic approach, the usefulness of the same method for concrete programs is argued. This is shown using an example of a correctness proof of an implementation of unbounded semaphore by binary semaphores. 8 references.

The use of concurrent engineering in the design of space missions allows to take into account in an interrelated methodology the high level of coupling and iteration of mission subsystems in the preliminary conceptual phase. This work presents the result of applying concurrent engineering in a short time lapse to design the main elements of the preliminary design for a lunar exploration mission, developed within ESA Academy Concurrent Engineering Challenge 2017. During this program, students of the Master in Space Systems at Technical University of Madrid designed a low cost satellite to find water on the Moon south pole as prospect of a future human lunar base. The resulting mission, The Moon Explorer And Observer of Water/Ice (MEOW) compromises a 262 kg spacecraft to be launched into a Geostationary Transfer Orbit as a secondary payload in the 2023/2025 time frame. A three months Weak Stability Boundary transfer via the Sun-Earth L1 Lagrange point allows for a high launch timeframe flexibility. The different aspects of the mission (orbit analysis, spacecraft design and payload) and possibilities of concurrent engineering are described.

Purpose: A prospective Phase II trial was carried out to evaluate the effectiveness of erythropoietin in improving or maintaining performance status as determined by the Karnofsky performance status (KPS) score and hemoglobin (Hb) levels in lung cancer patients treated with concurrent chemoradiation (CH-RT). Methods and Materials: A total of 51 patients with lung cancer (11 with small-cell, limited stage and 40 with non-small-cell disease, 17 with Stage IIIA and 23 with Stage IIIB), who underwent three different concurrent CH-RT protocols were enrolled. Baseline Hb and KPS values were recorded, as were the nadir Hb and KPS values before concurrent CH-RT. The final Hb and KPS values were recorded the last week of concurrent CH-RT. An Hb level of ≤11 g/dL before concurrent CH-RT was required before receiving erythropoietin. Prognostic factors for KPS improvement and survival were assessed by univariate and multivariate studies. Results: Of the 51 patients, 47 (92.3%) were men (mean age 63.6 years, range 40-75). The median baseline KPS score was 80, and the mean baseline Hb was 12.2 ± 1.76 g/dL (range 9-16.9). The mean nadir and final Hb value was 9.98±0.67 g/dL (range 8.6-11) and 11.33±1.59 g/dL (range 6.9-14.4), respectively. A significant increase was seen in the Hb and KPS score (p<0.05) in the final measurements. Differences were found between the final and nadir Hb in the predictive value for differences in performance status (p=0.001). On univariate study, pathologic findings (p=0.0234), weight loss (p=0.0049), baseline Hb (p=0.0057), and final Hb improvement (p=0.0237) were prognostic factors for survival. Nadir Hb (p=0.027), final Hb improvement (p=0.0069), pathologic findings (p = 0.0006), and weight loss (p=0.0001) had significant prognostic value for survival in multivariate analysis. Conclusion: In this study, erythropoietin appears to have a significant, beneficial impact on the KPS and Hb of patients undergoing concurrent CH-RT

This study examined the impact of the Great Recession of 2007-2009 on public health insurance enrollment and expenditures in Alabama. Our analysis was designed to provide a framework for other states to conduct similar analyses to better understand the relationship between macroeconomic conditions and public health insurance costs. We analyzed enrollment and claims data from Medicaid and the Children's Health Insurance Program (CHIP) in Alabama from 1999 through 2011. We examined the relationship between county-level unemployment rates and enrollment in Medicaid and CHIP, as well as total county-level expenditures in the two programs. We used linear regressions with county fixed effects to estimate the impact of unemployment changes on enrollment and expenditures after controlling for population and programmatic changes in eligibility and cost sharing. A one-percentage-point increase in a county's unemployment rate was associated with a 4.3% increase in Medicaid enrollment, a 0.9% increase in CHIP enrollment, and an overall increase in public health insurance enrollment of 3.7%. Each percentage-point increase in unemployment was associated with a 6.2% increase in total public health insurance expenditures on children, with Medicaid spending rising by 7.5% and CHIP spending rising by 1.8%. In response to the 6.4 percentage-point increase in the state's unemployment rate during the Great Recession, combined enrollment of children in Alabama's public health insurance programs increased by 24% and total expenditures rose by 40%. Recessions have a substantial impact on the number of children enrolled in CHIP and Medicaid, and a disproportionate impact on program spending. Programs should be aware of the likely magnitudes of the effects in their budget planning.

A study of lock-free based concurrent garbage collectors for multicore platform.

Wu, Hao; Ji, Zhen-Zhou

2014-01-01

Concurrent garbage collectors (CGC) have recently obtained extensive concern on multicore platform. Excellent designed CGC can improve the efficiency of runtime systems by exploring the full potential processing resources of multicore computers. Two major performance critical components for designing CGC are studied in this paper, stack scanning and heap compaction. Since the lock-based algorithms do not scale well, we present a lock-free solution for constructing a highly concurrent garbage collector. We adopt CAS/MCAS synchronization primitives to guarantee that the programs will never be blocked by the collector thread while the garbage collection process is ongoing. The evaluation results of this study demonstrate that our approach achieves competitive performance.

Understanding girls' enrollment at Louise's Farm School: A qualitative case study

Science.gov (United States)

Nowak, Ashley E. P.

This thesis presents a qualitative case study of enrollment and retention considerations at Louise's Farm School (LFS) in Palmer, Alaska, with a focus on how gender is performed in this domain. Interviews with 25 students, 12 parents, and 14 instructors revealed the enrollment decision-making process, identifying constraints to and enablers of girls' participation. Findings included three primary factors as greatly influencing girls' enrollment: (1) mothers' backgrounds; (2) mothers' knowledge of and the misperceptions regarding outcomes of LFS programing; and (3) girls' interest in LFS curriculum. Findings also exposed differences in mothers' and instructors' expectations for the educative development of girls and boys, suggesting that there is greater pressure on girls to perform academically while boys are expected to need greater space for physical expression.

Purpose: Virtually all patients with malignant glioma (MG) eventually recur. This study evaluates the safety of concurrent stereotactic radiosurgery (SRS) and bevacizumab (BVZ), an antiangiogenic agent, in treatment of recurrent MG. Methods and Materials: Fifteen patients with recurrent MG, treated at initial diagnosis with surgery and adjuvant radiation therapy/temozolomide and then at least 1 salvage chemotherapy regimen, were enrolled in this prospective trial. Lesions <3 cm in diameter were treated in a single fraction, whereas those 3 to 5 cm in diameter received 5 5-Gy fractions. BVZ was administered immediately before SRS and 2 weeks later. Neurocognitive testing (Mini-Mental Status Exam, Trail Making Test A/B), Functional Assessment of Cancer Therapy-Brain (FACT-Br) quality-of-life assessment, physical exam, and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) were performed immediately before SRS and 1 week and 2 months following completion of SRS. The primary endpoint was central nervous system (CNS) toxicity. Secondary endpoints included survival, quality of life, microvascular properties as measured by DCE-MRI, steroid usage, and performance status. Results: One grade 3 (severe headache) and 2 grade 2 CNS toxicities were observed. No patients experienced grade 4 to 5 toxicity or intracranial hemorrhage. Neurocognition, quality of life, and Karnofsky performance status did not change significantly with treatment. DCE-MRI results suggest a significant decline in tumor perfusion and permeability 1 week after SRS and further decline by 2 months. Conclusions: Treatment of recurrent MG with concurrent SRS and BVZ was not associated with excessive toxicity in this prospective trial. A randomized trial of concurrent SRS/BVZ versus conventional salvage therapy is needed to establish the efficacy of this approach

Helping concerned family members of individuals with substance use and concurrent disorders: An evaluation of a family member-oriented treatment program.

Denomme, William James; Benhanoh, Orry

2017-08-01

There is a growing body of research demonstrating that families of individuals with substance use and concurrent disorders (SUCD) experience a wide range of biopsychosocial problems that significantly impedes their quality of life and health. However, there has been a relative lack of treatment programs primarily focused on improving the well-being and quality of life of these family members. The current study assessed the efficacy of such a program at reducing stress, increasing perceived social support from family and friends, and increasing general, dyadic, and self-rated family functioning within these concerned family members. A sample of 125 family members of individuals with SUCDs was recruited, of which 97 participated in the treatment program and 28 were used as the comparison group. Results indicated that the treatment program significantly reduced stress, increased perceived social support from family and friends, and increased general, dyadic and self-rated family functioning. A perceived personal benefits questionnaire demonstrated that participants had a better understanding of SUCDs, better coping capabilities in regard to emotional difficulties, adopted stronger coping methods, participated in more leisure activities, and improved their relationship with the individual with a SUCD. The results of the current study further demonstrate the need to implement more of these family-member oriented psycho-educational treatment programs. Copyright © 2017 Elsevier Inc.

2017-09-01

Recent breast cancer treatment guidelines recommend that higher-risk premenopausal patients should receive ovarian function suppression (OFS) as part of adjuvant endocrine therapy. If chemotherapy is also given, it is uncertain whether to select concurrent or sequential OFS initiation. We analyzed 1872 patients enrolled in the randomized phase III TEXT and SOFT trials who received adjuvant chemotherapy for hormone receptor-positive, HER2-negative breast cancer and upon randomization to an OFS-containing adjuvant endocrine therapy, initiated gonadotropin-releasing-hormone-agonist triptorelin. Breast cancer-free interval (BCFI) was compared between patients who received OFS concurrently with chemotherapy in TEXT (n = 1242) versus sequentially post-chemotherapy in SOFT (n = 630). Because timing of trial enrollment relative to adjuvant chemotherapy differed, we implemented landmark analysis re-defining BCFI beginning 1 year after final dose of chemotherapy (median, 15.5 and 8.1 months from enrollment to landmark in TEXT and SOFT, respectively). As a non-randomized treatment comparison, we implemented comparative-effectiveness propensity score methodology with weighted Cox modeling. Distributions of several clinico-pathologic characteristics differed between groups. Patients who were premenopausal post-chemotherapy in SOFT were younger on average. The median duration of adjuvant chemotherapy was 18 weeks in both groups. There were 231 (12%) BC events after post-landmark median follow-up of about 5 years. Concurrent use of triptorelin with chemotherapy was not associated with a significant difference in post-landmark BCFI compared with sequential triptorelin post-chemotherapy, either in the overall population (HR = 1.11, 95% CI 0.72-1.72; P = 0.72; 4-year BCFI 89% in both groups), or in the subgroup of 692 women SOFT after about 5 years median follow-up, with limited statistical power especially for the subgroup <40 years, neither

Full Text Available Concurrent garbage collectors (CGC have recently obtained extensive concern on multicore platform. Excellent designed CGC can improve the efficiency of runtime systems by exploring the full potential processing resources of multicore computers. Two major performance critical components for designing CGC are studied in this paper, stack scanning and heap compaction. Since the lock-based algorithms do not scale well, we present a lock-free solution for constructing a highly concurrent garbage collector. We adopt CAS/MCAS synchronization primitives to guarantee that the programs will never be blocked by the collector thread while the garbage collection process is ongoing. The evaluation results of this study demonstrate that our approach achieves competitive performance.

Full Text Available Post-secondary experiences for students still in high school have been promoted as a means to increase academic rigor and create a better-trained workforce. Yet little is known regarding supports needed to significantly increase such options. This study obtained input from 411 stakeholders in one Midwestern state, including 201 district superintendents, 181 high school principals, and 23 college dual enrollment officers regarding their use of these options, their perceptions of barriers to program expansion, and their ranking of possible solutions to overcome the barriers. Findings demonstrate that all parties find postsecondary options of value, with traditional dual enrollment the most used option. Although all groups identified funding as a primary barrier, other systemic barriers were of great concern. Participants suggest that expansion of Advanced Placement and early and middle college programs, financial assistance for dually enrolled students, and increased program availability for career and technical options would be beneficial.Wozniak, Carl, (2012.

Mindfulness-Based Stress Reduction (MBSR) is associated with reduced depressive symptoms, quality of life improvements, behavioral activation, and increased acceptance among veterans. This study was conducted to increase the reach and impact of a veterans' MBSR program by identifying barriers to enrollment and participation to inform modifications in program delivery. Verify or challenge suspected barriers, and identify previously unrecognized barriers, to enrollment and participation in MBSR among veterans. A retrospective qualitative analysis of semistructured interviews. VA Puget Sound Health Care System (Seattle, WA). 68 interviewed, and 48 coded and analyzed before reaching saturation. Content analysis of semistructured interviews. Of the participants who enrolled, most (78%) completed the program and described MBSR positively. Veterans identified insufficient or inaccurate information, scheduling issues, and an aversion to groups as barriers to enrollment. Participants who discontinued the program cited logistics (e.g., scheduling and medical issues), negative reactions to instructors or group members, difficulty understanding the MBSR practice purposes, and struggling to find time for the practices as barriers to completion. Other challenges (cohort dynamics, teacher impact on group structure and focus, instructor lack of military service, and physical and psychological challenges) did not impede participation; we interpreted these as growth-facilitating challenges. Common conditions among veterans (chronic pain, posttraumatic stress disorder, and depression) were not described as barriers to enrollment or completion. Women-only MBSR groups and tele-health MBSR groups could improve accessibility to MBSR for veterans by addressing barriers such as commute anxiety, time restrictions, and an aversion to mixed gender groups among women. Educating MBSR teachers about veteran culture and health challenges faced by veterans, adding psychoeducation materials that

Pancreatic cancer is a highly virulent disease with a poor prognosis. Although objective tumor response to chemotherapy and/or radiotherapy is low, some patients show an improvement in their symptoms after treatments, without obvious tumor regression. We assessed the clinical benefit of concurrent chemoradiotherapy with protracted 5-fluorouracil infusion in patients with locally advanced pancreatic cancer. Sixteen patients were enrolled in this study. The clinical benefit response to the chemoradiotherapy was evaluated by 2 indicators, including pain (intensity of pain and consumption of morphine) and performance status. A patient was defined to be a clinical benefit responder if 1 of these 2 variables was positive, and the other variable was positive or stable. Seven patients (44%) responded. Six patients (38%) were classified as stable, and 3 (19%) as nonresponders. The survival period in responders was significantly longer than that in nonresponders and stable patients. Concurrent external-beam radiation therapy, with protracted 5-fluorouracil infusion, may be a meaningful treatment for locally advanced pancreatic cancer. (author)

2018-06-01

The effects of concurrent strength and endurance training have been well studied in untrained and moderately-trained individuals. However, studies examining these effects in individuals with a long history of resistance training (RT) are lacking. Additionally, few studies have examined how strength and power are affected when different types of endurance training are added to an RT protocol. The purpose of the present study was to compare the effects of concurrent training incorporating either low-volume, high-intensity interval training (HIIT, 8-24 Tabata intervals at ~150% of VO 2max ) or high-volume, medium-intensity continuous endurance training (CT, 40-80 min at 70% of VO 2max ), on the strength and power of highly-trained individuals. Sixteen highly-trained ice-hockey and rugby players were divided into two groups that underwent either CT (n = 8) or HIIT (n = 8) in parallel with RT (2-6 sets of heavy parallel squats, > 80% of 1RM) during a 6-week period (3 sessions/wk). Parallel squat performance improved after both RT + CT and RT + HIIT (12 ± 8% and 14 ± 10% respectively, p HIIT (4 ± 3%, p HIIT in athletes with a prior history of RT. This indicates that the volume and/or intensity of the endurance training does not influence the magnitude of strength improvements during short periods of concurrent training, at least for highly-trained individuals when the endurance training is performed after RT. However, since VO 2max improved only after RT + HIIT and this is a time efficient protocol, we recommend this type of concurrent endurance training.

2004-01-01

Maternal employment has been one of the greatest barriers to breastfeeding. Women are increasingly solving this problem by expressing milk at work and taking it home to their infants. The objective was to determine duration of breast milk expression among working mothers enrolled in an employer-sponsored lactation program. Retrospective reviews were conducted on the lactation records of 462 women employed by 5 corporations in order to describe and characterize their experiences. The lactation program included the employees' choice of (a) a class on the benefits of breastfeeding; (b) services of a certified lactation consultant (CLC); and (c) private room in the workplace with equipment for pumping. Breastfeeding was initiated by 97.5% of the participants, with 57.8% continuing for at least 6 months. Of the 435 (94.2%) who returned to work after giving birth, 343 (78.9%) attempted pumping milk at work, and 336 (98%) were successful. They expressed milk in the workplace for a mean of 6.3 months (SD = 3.9, range 2 weeks to 21 months). The mean age of infants when the mothers stopped pumping at work was 9.1 months (SD = 4.1, range 1.9 to 25 months). Most of the women who pumped their milk at work were working full time (84.2%). The mean postnatal maternity leave was 2.8 months. The proportion of women who chose to pump at work was higher among women who were salaried than among those who were paid hourly wages (p < 0.01). Company-sponsored lactation programs can enable employed mothers to provide breast milk for their infants as long as they wish, thus helping the nation attain the Healthy People 2010 goals of 50% of mothers breastfeeding until their infants are 6-months-old.

Schoendorf, Kenneth C.

2014-01-01

Objectives. We examined gap length, characteristics associated with gap length, and number of enrollment periods among Medicaid-enrolled children in the United States. Methods. We linked the 2004 National Health Interview Survey to Medicaid Analytic eXtract files for 1999 through 2008. We examined linkage-eligible children aged 5 to 13 years in the 2004 National Health Interview Survey who disenrolled from Medicaid. We generated Kaplan-Meier curves of time to reenrollment. We used Cox proportional hazards models to assess the effect of sociodemographic variables on time to reenrollment. We compared the percentage of children enrolled 4 or more times across sociodemographic groups. Results. Of children who disenrolled from Medicaid, 35.8%, 47.1%, 63.5%, 70.8%, and 79.1% of children had reenrolled in Medicaid by 6 months, 1, 3, 5, and 10 years, respectively. Children who were younger, poorer, or of minority race/ethnicity or had lower educated parents had shorter gaps in Medicaid and were more likely to have had 4 or more Medicaid enrollment periods. Conclusions. Nearly half of US children who disenrolled from Medicaid reenrolled within 1 year. Children with traditionally high-risk demographic characteristics had shorter gaps in Medicaid enrollment and were more likely to have more periods of Medicaid enrollment. PMID:25033135

2017-06-01

Full Text Available Background: In elderly patients who have atrial fibrillation (AF, surgical ablation of the arrhythmia during cardiac surgery may be challenging. Despite the reported advantages of ablating AF with the Cox maze procedure (CMP, the addition of the CMP may complicate other cardiac operations. We evaluated the effect of the CMP in elderly patients concurrent with other cardiac operations. Methods: From October 2007 to December 2015, we enrolled 27 patients aged ＞70 years who had AF and who underwent the CMP concurrently with other cardiac operations. The mean preoperative additive European System for Cardiac Operative Risk Evaluation score was 8±11 (high risk. Results: Only 1 hospital death occurred (4%. The Kaplan-Meier method showed a high 5‐year cumulative survival rate (92%. At mean follow‐up of 51 months, 23 patients (89% had sinus rhythm conversion. The postoperative left atrial dimensions did not significantly differ between the 8 patients who had reduction plasty for giant left atrium (53.4±7.5 cm and the 19 patients who did not have reduction plasty (48.7±5.7 cm. Conclusion: In patients aged ＞70 years, concurrent CMP may be associated with a high rate of sinus rhythm conversion without increased surgical risk, despite the added complexity of the main cardiac procedure.

Full Text Available China’s emergence as a global economic and political power is in part due to the country’s renewed involvement with, and commitment to, graduate higher education (Harris, 2005. Graduate education in China is viewed as the means of producing the essential scientists, engineers and skilled workforce needed to sustain the country’s rapid industrial growth and economic development. But how does China’s graduate education system compare with North American graduate higher education and what can each learn from the other? This paper examines the trends and patterns in Master’s level graduate education programs in China and Canada based on enrolment data gathered from 1999 to 2005. Initial comparisons of the data find that Master’s level enrolments in China are growing faster than in Canada; enrolment pattern distributions for both countries are unbalanced geographically and from a disciplinary perspective the highest number of Master’s level enrolments in Canada were in the business and management disciplines while in China the greatest Master’s level enrolments were in engineering. The comparisons provided by this study help identify some of the trends and challenges of graduate education at both the national and the regional levels of both countries.

Hihn, Jairus; Chattopadhyay, Debarati; Karpati, Gabriel; McGuire, Melissa; Panek, John; Warfield, Keith; Borden, Chester

2011-01-01

As aerospace missions grow larger and more technically complex in the face of ever tighter budgets, it will become increasingly important to use concurrent engineering methods in the development of early conceptual designs because of their ability to facilitate rapid assessments and trades of performance, cost and schedule. To successfully accomplish these complex missions with limited funding, it is essential to effectively leverage the strengths of individuals and teams across government, industry, academia, and international agencies by increased cooperation between organizations. As a result, the existing concurrent engineering teams will need to increasingly engage in distributed collaborative concurrent design. The purpose of this white paper is to identify a near-term vision for the future of distributed collaborative concurrent engineering design for aerospace missions as well as discuss the challenges to achieving that vision. The white paper also documents the advantages of creating a working group to investigate how to engage the expertise of different teams in joint design sessions while enabling organizations to maintain their organizations competitive advantage.

To determine the maximum tolerated dose (MTD) of vorinostat, a histone deacetylase inhibitor, given concurrently with stereotactic radiosurgery (SRS) to treat non-small cell lung cancer (NSCLC) brain metastases. Secondary objectives were to determine toxicity, local failure, distant intracranial failure, and overall survival rates. In this multicenter study, patients with 1 to 4 NSCLC brain metastases, each ≤2 cm, were enrolled in a phase 1, 3 + 3 dose escalation trial. Vorinostat dose levels were 200, 300, and 400 mg orally once daily for 14 days. Single-fraction SRS was delivered on day 3. A dose-limiting toxicity (DLT) was defined as any Common Terminology Criteria for Adverse Events version 3.0 grade 3 to 5 acute nonhematologic adverse event related to vorinostat or SRS occurring within 30 days. From 2009 to 2014, 17 patients were enrolled and 12 patients completed study treatment. Because no DLTs were observed, the MTD was established as 400 mg. Acute adverse events were reported by 10 patients (59%). Five patients discontinued vorinostat early and withdrew from the study. The most common reasons for withdrawal were dyspnea (n=2), nausea (n=1), and fatigue (n=2). With a median follow-up of 12 months (range, 1-64 months), Kaplan-Meier overall survival was 13 months. There were no local failures. One patient (8%) at the 400-mg dose level with a 2.0-cm metastasis developed histologically confirmed grade 4 radiation necrosis 2 months after SRS. The MTD of vorinostat with concurrent SRS was established as 400 mg. Although no DLTs were observed, 5 patients withdrew before completing the treatment course, a result that emphasizes the need for supportive care during vorinostat administration. There were no local failures. A larger, randomized trial may evaluate both the tolerability and potential local control benefit of vorinostat concurrent with SRS for brain metastases.

Miyazaki, Aya; Inaba, Hiroyuki; Tsuda, Takashi; Itoh, Fumio

2005-01-01

Concurrent chemoradiotherapy (CRT) for esophageal cancer is expected to achieve adequate quality of life (QOL) and to improve the survival of patients. As a QOL-oriented therapy for esophageal cancer, concurrent CRT with tegafur·gimestat·otastat potassium (TS-1)/nedaplatin (CDGP) was developed and evaluated. Between June 2001 and September 2002, 18 patients with esophageal cancer were enrolled in a clinical study of concurrent CRT with TS-1/CDGP. To evaluate the impact of treatment on the QOL, the patients were asked to answer QOL Questionnaire for Cancer Patients Treated with Anticancer Drugs (QOL-ACD) before and after therapy. The response rate was 66.7%, with a complete response occurring in 9 (50.0%) of the 18 patients. Patients with improved global, functional, or mental QOL after therapy showed or tended to show a significant, longer survival. Compared to patients previously treated by the same regimen with 5-fluorouracil (5-FU) instead of TS-1, those receiving the present therapy were able to leave hospital more frequently during treatment. TS-1/CDGP-based CRT for esophageal cancer exhibited comparable antitumor activity and survival benefit as with standard 5-FU/cisplatin (CDDP)-based CRT without causing serious side-effects. The patients receiving the present therapy seemed to have a better chance of maintaining their QOL. (author)

This randomised phase III study was conducted to investigate the efficacy of extended nodal irradiation (ENI) and/or erlotinib in inoperable oesophageal squamous cell cancer (ESCC). Patients with histologically confirmed locally advanced ESCC or medically inoperable disease were randomly assigned (ratio 1:1:1:1) to one of four treatment groups: group A, radiotherapy adoption of ENI with two cycles of concurrent TP chemotherapy (paclitaxel 135 mg/m 2  day 1 and cisplatin 20 mg/m 2 days 1-3, every 4 weeks) plus erlotinib (150 mg per day during chemoradiotherapy); group B, radiotherapy adoption of ENI with two cycles of concurrent TP; group C, radiotherapy adoption of conventional field irradiation (CFI) with two cycles of concurrent TP plus erlotinib; group D, radiotherapy adoption of CFI with two cycles of concurrent TP. A total of 352 patients (88 assigned to each treatment group) were enrolled. The 2-year overall survival rates of group A, B, C and D were 57.8%, 49.9%, 44.9% and 38.7%, respectively (P = 0.015). Group A significantly improved 2-year overall survival compared with group D. The ENI significantly improved overall survival in patients with inoperable ESCC (P = 0.014). The addition of erlotinib significantly decreased loco-regional recurrence (P = 0.042). Aside from rash and radiation oesophagitis, the incidence of grade 3 or greater toxicities did not differ among 4 groups. Chemoradiotherapy with ENI and erlotinib might represent a substantial improvement on the standard of care for inoperable ESCC. ENI alone should be adopted in concurrent chemoradiotherapy for ESCC patients. Copyright © 2018 Elsevier Ltd. All rights reserved.

Educators' expectations of roles, employability and career pathways of registered and enrolled nurses in Australia.

Jacob, Elisabeth R; McKenna, Lisa; D'Amore, Angelo

2016-01-01

In Australia, like other countries, two levels of nurse are registered for entry to practice. Educational changes for second level nurses in Australia have led to questions regarding roles and career options. This paper reports on interviews with nursing course coordinators to examine educator expectations of roles and career pathways of registered and enrolled nurses. Coordinators of eight degree (registered) and diploma (enrolled) nursing programs were interviewed to determine their opinions on roles and careers that students were prepared for. Transcripts were thematically analysed. Educators reported similar graduate roles, although high acuity care was primarily the role of registered nurses. Career expectations differed with enrolled nurses having limited advancement opportunity, and registered nurses greater career options. Health organisations were unprepared to accommodate increased practice scope of enrolled nurses and limited work practice through policies stipulating who could perform procedures. Organisational health policies need to accommodate increased enrolled nurse skill base. Education of practising nurses is necessary regarding increased scope of enrolled nurse practice to ensure they are used to their full potential. Increasing patient acuity requires more registered nurses, as enrolled nurses are unprepared to care for complex or deteriorating patients. Copyright © 2015 Elsevier Ltd. All rights reserved.

Long-distance truck drivers have been shown to be a critical population in the spread of HIV in Africa. In 2009, surveys with 385 Ugandan long-distance truck drivers measured concurrency point prevalence with two methods; it ranged from 37.4% (calendar-method) to 50.1% (direct question). The majority (84%) of relationships reported were long-term resulting in a long duration of overlap (average of 58 months) across concurrent partnerships. Only 7% of these men reported using any condoms with their spouses during the past month. Among all non-spousal relationships, duration of relationship was the factor most strongly associated with engaging in unprotected sex in the past month in a multivariable analyses controlling for partner and relationship characteristics. Innovative intervention programs for these men and their partners are needed that address the realities of truck drivers' lifestyles.

The recommendations for exercise training and physical activity for older adults include cardiovascular and resistance training components (CVT and RT, respectively). The purpose of the present investigation was to compare the fitness benefits of concurrent CVT and RT with those attained through an equivalent duration of CVT or RT alone. Thirty-six participants (ages 60-84) were assigned to a control group or to one of three exercise treatment groups. The treatment groups exercised three times per week for 12 wk using RT (N = 11), CVT (N = 10), or CVT and RT (BOTH, N = 9). Pre- and post-training, participants performed a submaximal exercise test (GXT), five repetition-maximum strength tests (5RM), and the AAHPERD functional fitness test for older adults. All exercise treatment groups revealed lower resting heart rate and rate-pressure product; lower exercise diastolic blood pressure and rating of perceived exertion; increased GXT duration; increased leg, back, and shoulder 5RM scores; and improved AAHPERD flexibility, coordination, and cardiovascular endurance scores. The exercise treatment groups responded differently on the following: RT and BOTH enhanced arm and chest strength more than CVT; and BOTH enhanced AAHPERD strength and agility scores more than CVT or RT. Concurrent CVT and RT is as effective in eliciting improvements in cardiovascular fitness and 5RM performance as CVT or RT, respectively. Moreover, incorporating both CVT and RT in exercise programs for older adults may be more effective in optimizing aspects of functional fitness than programs that involve only one component.

Concurrent radiotherapy and chemotherapy

International Nuclear Information System (INIS)

Fu, K.K.

1985-01-01

The principal objective of combining chemotherapy with radiotherapy (XRT) for the treatment of advanced head and neck cancer is to improve the therapeutic ratio through the enhancement of local control and reduction of distant metastases without excessively enhancing normal tissue effects. Improved tumour control can result from sole additivity of either therapy or direct interactions between drug and radiation leading to increased tumour cell kill. Chemotherapy may sensitize the cells to radiation, interfere with repair of sublethal or potentially lethal radiation damage, induce cell synchrony, and reduce tumour mass leading to reoxygenation and decreased fraction of resistant hypoxic cells. Radiation may improve drug accessibility to tumour cells and reduce tumour volume leading to increased cell proliferation and chemosensitivity. If the enhanced effects of combined therapy are purely additive, then the two modalities can be administered either sequentially or concurrently with the same results. However, if the enhanced effects result from the direct interaction between drug and radiation, it is necessary that the two modalities be administered concurrently and in close temporal proximity. This review summarizes the results of clinical studies in which chemotherapy was administered concurrently during the course of radiotherapy for patients with previously untreated advanced squamous cell carcinoma in the head and neck

Research suggests that community involvement is integral to solving public health problems, including involvement in clinical trials-a gold standard. Significant racial/ethnic disparities exist in the accrual of participants for clinical trials. Location and cultural aspects of clinical trials influence recruitment and accrual to clinical trials. It is increasingly necessary to be aware of defining characteristics, such as location and culture of the populations from which research participants are enrolled. Little research has examined the effect of location and cultural competency in adapting clinical trial research for minority and underserved communities on accrual for clinical trials. Utilizing embedded community academic sites, the authors applied cultural competency frameworks to adapt clinical trial research in order to increase minority participation in nontherapeutic cancer clinical trials. This strategy resulted in successful accrual of participants to new clinical research trials, specifically targeting participation from minority and underserved communities in metropolitan Washington, DC. From 2012 to 2014, a total of 559 participants enrolled across six nontherapeutic clinical trials, representing a 62% increase in the enrollment of blacks in clinical research. Embedding cancer prevention programs and research in the community was shown to be yet another important strategy in the arsenal of approaches that can potentially enhance clinical research enrollment and capacity. The analyses showed that the capacity to acquire cultural knowledge about patients-their physical locales, cultural values, and environments in which they live-is essential to recruiting culturally and ethnically diverse population samples.

2016-05-01

Purpose: To determine, in the setting of locally advanced pancreatic cancer, the maximum tolerated dose of carbon ion radiation therapy (C-ion RT) and gemcitabine dose delivered concurrently and to estimate local effect and survival. Methods and Materials: Eligibility included pathologic confirmation of pancreatic invasive ductal carcinomas and radiographically unresectable disease without metastasis. Concurrent gemcitabine was administered on days 1, 8, and 15, and the dose levels were escalated from 400 to 1000 mg/m{sup 2} under the starting dose level (43.2 GyE) of C-ion RT. The dose levels of C-ion RT were escalated from 43.2 to 55.2 GyE at 12 fractions under the fixed recommended gemcitabine dose determined. Results: Seventy-six patients were enrolled. Among the 72 treated patients, dose-limiting toxicity was observed in 3 patients: grade 3 infection in 1 patient and grade 4 neutropenia in 2 patients. Only 1 patient experienced a late grade 3 gastric ulcer and bleeding 10 months after C-ion RT. The recommended dose of gemcitabine with C-ion RT was found to be 1000 mg/m{sup 2}. The dose of C-ion RT with the full dose of gemcitabine (1000 mg/m{sup 2}) was safely increased to 55.2 GyE. The freedom from local progression rate was 83% at 2 years using the Response Evaluation Criteria in Solid Tumors. The 2-year overall survival rates in all patients and in the high-dose group with stage III (≥45.6 GyE) were 35% and 48%, respectively. Conclusions: Carbon ion RT with concurrent full-dose gemcitabine was well tolerated and effective in patients with unresectable locally advanced pancreatic cancer.

Are behaviors at one alternative in concurrent schedules independent of contingencies at the other alternative?

Science.gov (United States)

MacDonall, James S

2017-09-01

Some have reported changing the schedule at one alternative of a concurrent schedule changed responding at the other alternative (Catania, 1969), which seems odd because no contingencies were changed there. When concurrent schedules are programmed using two schedules, one associated with each alternative that operate continuously, changing the schedule at one alternative also changes the switch schedule at the other alternative. Thus, changes in responding at the constant alternative could be due to the change in the switch schedule. To assess this possibility, six rats were exposed to a series of conditions that alternated between pairs of interval schedules at both alternatives and a pair of interval schedules at one, constant, alternative and a pair of extinction schedules at the other alternative. Comparing run lengths, visit durations and response rates at the constant alternative in the alternating conditions did not show consistent increases and decreases when a strict criterion for changes was used. Using a less stringent definition (any change in mean values) showed changes. The stay/switch analysis suggests it may be inaccurate to apply behavioral contrast to procedures that change from concurrent variable-interval variable-interval schedules to concurrent variable-interval extinction schedules because the contingencies in neither alternative are constant. © 2017 Society for the Experimental Analysis of Behavior.

David T Miyamoto

Full Text Available BACKGROUND: It is not known whether the addition of chemotherapy to radiation therapy improves outcomes in primary vaginal cancer. Here, we review clinical outcomes in patients with primary vaginal cancer treated with radiation therapy (RT or concurrent chemoradiation therapy (CRT. METHODS: Seventy-one patients with primary vaginal cancer treated with definitive RT with or without concurrent chemotherapy at a single institution were identified and their records reviewed. A total of 51 patients were treated with RT alone; 20 patients were treated with CRT. Recurrences were analyzed. Overall survival (OS and disease-free survival (DFS rates were estimated using the Kaplan-Meier method. Cox regression analysis was performed. RESULTS: The median age at diagnosis was 61 years (range, 18-92 years and the median follow-up time among survivors was 3.0 years. Kaplan-Meier estimates for OS and DFS differed significantly between the RT and CRT groups (3-yr OS = 56% vs. 79%, log-rank p = 0.037; 3-yr DFS = 43% vs. 73%, log-rank p = 0.011. Twenty-three patients (45% in the RT group had a relapse at any site compared to 3 (15% in the CRT group (p = 0.027. With regard to the sites of first relapse, 10 patients (14% had local only, 4 (6% had local and regional, 9 (13% had regional only, 1 (1% had regional and distant, and 2 (3% had distant only relapse. On univariate analysis, the use of concurrent chemotherapy, FIGO stage, tumor size, and date of diagnosis were significant predictors of DFS. On multivariate analysis, the use of concurrent chemotherapy remained a significant predictor of DFS (hazard ratio 0.31 (95% CI, 0.10-0.97; p = 0.04. CONCLUSIONS: Vaginal cancer results in poor outcomes. Adequate radiation dose is essential to ensure curative management. Concurrent chemotherapy should be considered for vaginal cancer patients.

2018-01-01

Full Text Available Empirically validated interventions addressing childhood psychological problems are now readily available, but success likely depends in part on accurately identifying which children will benefit from which intervention. This pilot study examined the stress activation and response system, first as a way to differentiate high versus low-risk children, and second to explore indicators of the stress system associated with favorable intervention response. Method. Participants (N = 43, 58% male were school-aged children who qualified for inclusion in the Early Risers “Skills for Success” Prevention Program based on their elevated levels of aggressive and/or socially withdrawn behavior and a normally developing comparison group. Compared to the normally developing group, children who were participants in the intervention exhibited a more blunted cortisol response to the stress paradigm. However, for the children in the intervention group, elevated cortisol levels at the start of the stress paradigm were concurrently associated with internalizing problems and predictive of improvement in internalizing problems over time. These findings provide preliminary evidence that hypothalamic pituitary adrenal (HPA axis biological variables may be helpful tools for identifying children who would benefit from intervention and personalizing interventions.

Concurrent analysis: towards generalisable qualitative research.

Science.gov (United States)

Snowden, Austyn; Martin, Colin R

2011-10-01

This study develops an original method of qualitative analysis coherent with its interpretivist principles. The objective is to increase the likelihood of achieving generalisability and so improve the chance of the findings being translated into practice. Good qualitative research depends on coherent analysis of different types of data. The limitations of existing methodologies are first discussed to justify the need for a novel approach. To illustrate this approach, primary evidence is presented using the new methodology. The primary evidence consists of a constructivist grounded theory of how mental health nurses with prescribing authority integrate prescribing into practice. This theory is built concurrently from interviews, reflective accounts and case study data from the literature. Concurrent analysis. Ten research articles and 13 semi-structured interviews were sampled purposively and then theoretically and analysed concurrently using constructivist grounded theory. A theory of the process of becoming competent in mental health nurse prescribing was generated through this process. This theory was validated by 32 practising mental health nurse prescribers as an accurate representation of their experience. The methodology generated a coherent and generalisable theory. It is therefore claimed that concurrent analysis engenders consistent and iterative treatment of different sources of qualitative data in a manageable manner. This process supports facilitation of the highest standard of qualitative research. Concurrent analysis removes the artificial delineation of relevant literature from other forms of constructed data. This gives researchers clear direction to treat qualitative data consistently raising the chances of generalisability of the findings. Raising the generalisability of qualitative research will increase its chances of informing clinical practice. © 2010 Blackwell Publishing Ltd.

To determine the predictors of participation in a smoking-cessation program among patients with head and neck cancer. This cross-sectional study is a substudy of a larger, randomized trial of patients with head and neck cancer that determined the predictors of smokers' participation in a cessation intervention. Otolaryngology clinics at three Veterans Affairs medical centers (Ann Arbor, MI, Gainesville, FL, and Dallas, TX), and the University of Michigan Hospital in Ann Arbor. 286 patients who had smoked within six months of the screening survey were eligible for a smoking-cessation intervention. Descriptive statistics and bivariate and multivariate logistic regression were used to determine the independent predictors of smokers' participation in an intervention study. Perceived difficulty quitting (as a construct of self-efficacy), health behaviors (i.e., smoking and problem drinking), clinical characteristics (i.e., depression and cancer site and stage), and demographic variables. Forty-eight percent of those eligible participated. High perceived difficulty quitting was the only statistically significant predictor of participation, whereas problem drinking, lower depressive symptoms, and laryngeal cancer site approached significance. Special outreach may be needed to reach patients with head and neck cancer who are overly confident in quitting, problem drinkers, and patients with laryngeal cancer. Oncology nurses are in an opportune position to assess patients' perceived difficulty quitting smoking and motivate them to enroll in cessation programs, ultimately improving quality of life, reducing risk of recurrence, and increasing survival for this population.

Health related quality of life in locally advanced NSCLC treated with high dose radiotherapy and concurrent chemotherapy or cetuximab – Pooled results from two prospective clinical trials

International Nuclear Information System (INIS)

Hallqvist, Andreas; Bergman, Bengt; Nyman, Jan

2012-01-01

Background: In non-small cell lung cancer (NSCLC) stage III, data on patient reported health-related quality of life (HRQL) are scarce, especially regarding concurrent chemoradiotherapy. Aims: To evaluate HRQL in patients treated with high dose radiotherapy combined with concurrent chemotherapy or the antibody cetuximab. Methods: The study population comprised all patients enroled in either of two phase II trials in locally advanced NSCLC performed in Sweden 2002–2007. The RAKET trial investigated three different ways of increasing local control (accelerated hyperfractionated treatment or concurrent daily or weekly chemotherapy). The Satellite trial evaluated the addition of cetuximab to thoracic irradiation. HRQL was measured at four time points: At baseline, before radiotherapy, 4–6 weeks after radiotherapy and at 3 months follow-up, using the EORTC QLQ-C30 and LC14 set of questionnaires. Results: 154/220 patients (65%) who completed HRQL assessments at all time points were included in the longitudinal study. There was a significant decline over time regarding most functioning measures. Dyspnoea and fatigue gradually deteriorated without recovery after completed treatment. Chemotherapy related symptoms showed a transient deterioration, whereas radiotherapy related esophagitis had not fully recovered at 3 months. Patients with stage IIIA disease tended to recover better regarding global QL, fatigue and dyspnoea compared to patients with stage IIIB. Patients with WHO performance status (PS) 0 reported improved global QL and less fatigue over time compared with PS 1. Concurrent chemotherapy was associated with more pronounced fatigue and dysphagia, and worse global QL compared with concurrent cetuximab. Baseline physical functioning was an independent predictor of overall survival. Conclusion: Patients undergoing high dose thoracic radiotherapy combined with chemotherapy or cetuximab reported a gradual deterioration in functioning, dyspnoea and fatigue, while

A case for evaluating sensor network protocols concurrently

KAUST Repository

Gnawali, Omprakash; Guibas, Leonidas; Levis, Philip

2010-01-01

Researchers typically evaluate and compare protocols on the testbeds by running them one at a time. This methodology ignores the variation in link qualities and wireless environment across these experiments. These variations can introduce significant noise in the results. Evaluating two protocols concurrently, however, suffers from inter-protocol interactions. These interactions can perturb performance even under very light load, especially timing and timing sensitive protocols. We argue that the benefits of running protocols concurrently greatly outweigh the disadvantages. Protocols rarely run in isolation in real networks, and so considering such interactions is valuable. Although the wireless environment is still uncontrolled, concurrent evaluations make comparisons fair and more statistically sound. Through experiments on two testbeds, we make the case for evaluating and comparing low data-rate sensor network protocols by running them concurrently. Copyright 2010 ACM.

Software defined radio (SDR) architecture for concurrent multi-satellite communications

Science.gov (United States)

Maheshwarappa, Mamatha R.

SDRs have emerged as a viable approach for space communications over the last decade by delivering low-cost hardware and flexible software solutions. The flexibility introduced by the SDR concept not only allows the realisation of concurrent multiple standards on one platform, but also promises to ease the implementation of one communication standard on differing SDR platforms by signal porting. This technology would facilitate implementing reconfigurable nodes for parallel satellite reception in Mobile/Deployable Ground Segments and Distributed Satellite Systems (DSS) for amateur radio/university satellite operations. This work outlines the recent advances in embedded technologies that can enable new communication architectures for concurrent multi-satellite or satellite-to-ground missions where multi-link challenges are associated. This research proposes a novel concept to run advanced parallelised SDR back-end technologies in a Commercial-Off-The-Shelf (COTS) embedded system that can support multi-signal processing for multi-satellite scenarios simultaneously. The initial SDR implementation could support only one receiver chain due to system saturation. However, the design was optimised to facilitate multiple signals within the limited resources available on an embedded system at any given time. This was achieved by providing a VHDL solution to the existing Python and C/C++ programming languages along with parallelisation so as to accelerate performance whilst maintaining the flexibility. The improvement in the performance was validated at every stage through profiling. Various cases of concurrent multiple signals with different standards such as frequency (with Doppler effect) and symbol rates were simulated in order to validate the novel architecture proposed in this research. Also, the architecture allows the system to be reconfigurable by providing the opportunity to change the communication standards in soft real-time. The chosen COTS solution provides a

Program Execution on Reconfigurable Multicore Architectures

Directory of Open Access Journals (Sweden)

Sanjiva Prasad

2016-06-01

Full Text Available Based on the two observations that diverse applications perform better on different multicore architectures, and that different phases of an application may have vastly different resource requirements, Pal et al. proposed a novel reconfigurable hardware approach for executing multithreaded programs. Instead of mapping a concurrent program to a fixed architecture, the architecture adaptively reconfigures itself to meet the application's concurrency and communication requirements, yielding significant improvements in performance. Based on our earlier abstract operational framework for multicore execution with hierarchical memory structures, we describe execution of multithreaded programs on reconfigurable architectures that support a variety of clustered configurations. Such reconfiguration may not preserve the semantics of programs due to the possible introduction of race conditions arising from concurrent accesses to shared memory by threads running on the different cores. We present an intuitive partial ordering notion on the cluster configurations, and show that the semantics of multithreaded programs is always preserved for reconfigurations "upward" in that ordering, whereas semantics preservation for arbitrary reconfigurations can be guaranteed for well-synchronised programs. We further show that a simple approximate notion of efficiency of execution on the different configurations can be obtained using the notion of amortised bisimulations, and extend it to dynamic reconfiguration.

Sustaining enrollment in health insurance for vulnerable populations: lessons from Massachusetts.

Capoccia, Victor; Croze, Colette; Cohen, Martin; O'Brien, John P

2013-04-01

Since 2008 Massachusetts has had universal health insurance with an individual mandate. As a result, only about 3% of the population is uninsured. However, patients who use behavioral health services are uninsured at much higher rates. This 2011 study sought to understand reasons for the discrepancy and identify approaches to reduce disenrollment and sustain coverage. The qualitative study was based on structured interviews and focus groups. Structured interviews were conducted with 15 policy makers, consumer advocates, and chief executive officers of provider organizations, and three focus groups were held with 33 patient volunteers. The interviews and focus groups identified several disenrollment opportunities, all of which contribute to "churn" (the process by which disenrolled persons who remain eligible are reenrolled in the same or a different plan): missing and incomplete documentation, acute and chronic conditions and long-term disabilities that interfere with a patient's ability to respond to program communications, and lack of awareness among beneficiaries of the consequences of changes that trigger termination and the need to transfer to another program. Although safeguards are built into the system to avoid some disenrollments, the policies and procedures that drive the system are built on a default assumption of ineligibility or disenrollment until the individual establishes eligibility and completes requirements. Practices that can sustain enrollment include real-time Web-based prepopulated enrollment and redetermination processes, redetermination flexibility for designated chronic illnesses, and standardized performance metrics for churn and associated costs. Changes in the information system infrastructure and in outreach, enrollment, disenrollment, and reenrollment procedures can improve continuity and retention of health insurance coverage.

Purpose: to determine the maximum tolerated dose (MTD) of gemcitabine every 2 weeks to a concurrent radiotherapy administered during an aggressive program of sequential and simultaneous radio-/chemotherapy for locally advanced, unresectable non-small cell lung cancer (NSCLC). Patients and methods: ten patients with histologically confirmed NSCLC were observed and treated in accordance with a combined radio-/chemotherapy protocol. This included two cycles of induction chemotherapy with gemcitabine (1,200 mg/m{sup 2}) and vinorelbine (30 mg/m{sup 2}) at days 1, 8 and 22, 29, followed by concurrent radiotherapy including [{sup 18}F] fluorodeoxyglucose positron emission tomography-(FDG-PET-) based target volume definition (2.0 Gy/d; total dose 66.0 Gy) and chemotherapy with gemcitabine every 2 weeks at days 43, 57, and 71. The initial dose was 300 mg/m{sup 2}. The dose of gemcitabine was increased by 100 mg/m{sup 2} until the MTD was realized. Three patients were enrolled for each dose level. Results: dose-limiting toxicity (DLT) was identified for the patient group receiving gemcitabine 500 mg/m{sup 2}, due to grade 2 esophagitis (next to grade 3) in all patients. 6 weeks after the completion of radio-/chemotherapy, most patients still presented treatment-induced esophagitis. In accordance with expected complications, such as esophagitis, dysphagia and odynophagia, the MTD was defined at this dose level, although no DLT grade 3 was reached. Conclusion: after induction chemotherapy, the MTD and frequency of gemcitabine in locally advanced NSCLC is 500 mg/m{sup 2} every 2 weeks during a maximum of 7 weeks of thoracic radiotherapy.

Electronic cigarettes (e-cigarettes) are being used as cessation aids by many smokers despite a lack of empirical evidence regarding their safety and efficacy. We analyzed the association of e-cigarette use and smoking abstinence in a population of smokers accessing standard smoking cessation treatment (nicotine replacement therapy [NRT] plus behavioral counseling) through primary care clinics in Ontario, Canada. Participants were recruited through 187 primary care clinics across Ontario, Canada and were eligible for up to 26 weeks of brief behavioral counseling and individualized dosing of NRT at no cost. Adjusted logistic regression models were used to examine the association between concurrent e-cigarette use and smoking abstinence at 3- and 6-month follow-ups. Of the 6526 participants who completed a 3-month follow-up, 18.1% reported using an e-cigarette while in treatment. The majority of e-cigarette users (78.2%) reported using an e-cigarette for smoking cessation. At 3-month follow-up, e-cigarette use was negatively associated with abstinence after controlling for confounders (adjusted odds ratio [AOR] = 0.706, p E-cigarette use was also negatively associated with abstinence at 6-month follow-up (AOR = 0.502, p E-cigarette use was negatively associated with successful quitting in this large community sample of smokers accessing standard evidence-based smoking cessation treatment through primary care clinics, even after adjusting for covariates such as severity of tobacco dependence, gender, and age. The findings suggest that concurrent use of e-cigarettes with NRT may harm cessation attempts. This study confirms previous findings from observational studies regarding the negative association between e-cigarette use and smoking cessation, but in a large cohort of smokers enrolled in an evidence-based treatment program. The implications of these findings are that concurrent use of e-cigarettes during a quit attempt utilizing cost-free evidence-based treatment

This article is the first of a two-part series which argues for the concurrent management of the appropriateness, necessity, and quality of patient care. Intensifying scrutiny by the credentialing groups, the PROs and all third-party payors underscores the vital need to implement cost-effective information systems which integrate the departmentalized functions of patient-physician profiling, DRG case-mix analyses, length of stay monitoring, pre-admission/admission and continued stay review, discharge planning, risk management, incident reporting and quality review. In the domain of physician performance regarding admitting and practice patterns, the ability to exercise concurrent utilization-quality review means early detection and prevention of events which would otherwise result in denials of payment and/or compromised patient care. Concurrent utilization-quality review must, by definition, be managerially invasive and focused; hence, it is integral to maintaining the integrity of the services and product lines offered by the provider. In fact, if PPO status is a marketing agenda, then the institutional objectives of cost-effectiveness, productivity, value, and competitiveness can only be achieved through concurrent utilization-quality review.

2011-01-01

Purpose: To conduct and evaluate a two-phased community-based approach to recruit lower socioeconomic status, minority, or Spanish-speaking adults at risk of developing diabetes to a randomized trial of a lifestyle intervention program delivered by a public health department. Design: Within geographic areas comprising our target population, 4 community organizations provided local space for conducting the study and program. Phase I—outreach in venues surrounding these organizations—included diabetes education, a short diabetes risk appraisal (DRA), and diabetes risk screening based on a fasting fingerstick glucose test. Phase II—trial recruitment—began concurrently for those found to be at risk of developing diabetes in Phase I by explaining the study, lifestyle program, and research process. Those interested and eligible enrolled in the 1-year study. Results: Over 2 years, approximately 5,110 individuals received diabetes education, 1,917 completed a DRA, and 1,164 were screened of which 641 (55%) had an elevated fingerstick result of ≥106 mg/dl. Of the study sampling frame—persons over age 25 at risk of developing diabetes (N = 544)—238 (43%) enrolled in the trial; of those who were study eligible (n = 427), 56% enrolled. In the final sample, mean age was 56 years (SD = 17), 78% were ethnic minorities, 32% were Spanish-speaking, and 15% had a high school education or less. Implications: Providing diabetes health education and screening prior to study recruitment may help overcome barriers to research participation in underserved communities, thus helping address difficulties recruiting minority and older populations into research, particularly research pertaining to chronic disease risk factors.

2015-12-01

Full Text Available Well defined concurrent replicated data structure is very important to design collaborative editing system, particularly, certain properties like out-of-order execution of concurrent operations and data convergence. In this paper, we introduce novel linear data structure based on unique identifier scheme required for indexed communication. These identifiers are real numbers holding specific pattern of precision. Based on the uniqueness and the total order of these identifiers, here, we present two concurrency control techniques to achieve high degree of concurrency according to strong and lazy happened-before relations. Our data structure preserves data convergence, yields better performance and avoids overheads as compared to existing approaches.

Concurrent credit portfolio losses.

Sicking, Joachim; Guhr, Thomas; Schäfer, Rudi

2018-01-01

We consider the problem of concurrent portfolio losses in two non-overlapping credit portfolios. In order to explore the full statistical dependence structure of such portfolio losses, we estimate their empirical pairwise copulas. Instead of a Gaussian dependence, we typically find a strong asymmetry in the copulas. Concurrent large portfolio losses are much more likely than small ones. Studying the dependences of these losses as a function of portfolio size, we moreover reveal that not only large portfolios of thousands of contracts, but also medium-sized and small ones with only a few dozens of contracts exhibit notable portfolio loss correlations. Anticipated idiosyncratic effects turn out to be negligible. These are troublesome insights not only for investors in structured fixed-income products, but particularly for the stability of the financial sector. JEL codes: C32, F34, G21, G32, H81.

This paper proposes the new concurrent iterative methods without using any derivatives for finding all zeros of polynomials simultaneously. The new methods are of monotonic convergence for both simple and multiple real-zeros of polynomials and are quadratically convergent. The corresponding accelerated concurrent iterative methods are obtained too. The new methods are good candidates for the application in solving symmetric eigenproblems.

Multiparty Compatibility for Concurrent Objects

Directory of Open Access Journals (Sweden)

Roly Perera

2016-06-01

Full Text Available Objects and actors are communicating state machines, offering and consuming different services at different points in their lifecycle. Two complementary challenges arise when programming such systems. When objects interact, their state machines must be "compatible", so that services are requested only when they are available. Dually, when objects refine other objects, their state machines must be "compliant", so that services are honoured whenever they are promised. In this paper we show how the idea of multiparty compatibility from the session types literature can be applied to both of these problems. We present an untyped language in which concurrent objects are checked automatically for compatibility and compliance. For simple objects, checking can be exhaustive and has the feel of a type system. More complex objects can be partially validated via test cases, leading to a methodology closer to continuous testing. Our proof-of-concept implementation is limited in some important respects, but demonstrates the potential value of the approach and the relationship to existing software development practices.

PEACH™QLD translated the PEACH™ Program, designed to manage overweight/obesity in primary school-aged children, from efficacious RCT and small scale community trial to a larger state-wide program. This paper describes the lessons learnt when upscaling to universal health coverage. The 6-month, family-focussed program was delivered in Queensland, Australia from 2013 to 2016. Its implementation was planned by researchers who developed the program and conducted the RCT, and experienced project managers and practitioners across the health continuum. The intervention targeted parents as the agents of change and was delivered via parent-only group sessions. Concurrently, children attended fun, non-competitive activity sessions. Sessions were delivered by facilitators who received standardised training and were employed by a range of service providers. Participants were referred by health professionals or self-referred in response to extensive promotion and marketing. A pilot phase and a quality improvement framework were planned to respond to emerging challenges. Implementation challenges included engagement of the health system; participant recruitment; and engagement. A total of 1513 children (1216 families) enrolled, with 1122 children (919 families) in the face-to-face program (105 groups in 50 unique venues) and 391 children (297 families) in PEACH™ Online. Self-referral generated 68% of enrolments. Unexpected, concurrent and, far-reaching public health system changes contributed to poor program uptake by the sector (only 56 [53%] groups delivered by publicly-funded health organisations) requiring substantial modification of the original implementation plan. Process evaluation during the pilot phase and an ongoing quality improvement framework informed program adaptations that included changing from fortnightly to weekly sessions aligned with school terms, revision of parent materials, modification of eligibility criteria to include healthy weight children and

Concurrency-Induced Transitions in Epidemic Dynamics on Temporal Networks.

Social contact networks underlying epidemic processes in humans and animals are highly dynamic. The spreading of infections on such temporal networks can differ dramatically from spreading on static networks. We theoretically investigate the effects of concurrency, the number of neighbors that a node has at a given time point, on the epidemic threshold in the stochastic susceptible-infected-susceptible dynamics on temporal network models. We show that network dynamics can suppress epidemics (i.e., yield a higher epidemic threshold) when the node's concurrency is low, but can also enhance epidemics when the concurrency is high. We analytically determine different phases of this concurrency-induced transition, and confirm our results with numerical simulations.

Concurrent software system design supported by SARA at the age of one

Energy Technology Data Exchange (ETDEWEB)

Campos, I.M.; Estrin, G.

A multilevel modeling method suitable for the design of concurrent hardware or software systems is presented. The methodology is requirement driven and uses tools incorporated in a programming system called SARA (Systems ARchitect's Apprentice). Both top-down refinement and bottom-up abstraction are supported. The design of an asynchronous sender-receiver illustrates the key steps in going smoothly from programing in the large to programing in the small or actual code. The same methodology can be used to design hardware systems by applying different pragmatics from those proposed for software systems. SARA consists of a set of interactive tools implemented both at UCLA and also on the MIT-Multics system. Although SARA continues in long-term development, completed design tools are accessible for experimentation by authorized users at either location via the ARPANET. 9 figures, 2 tables.

Dual enrollment as a factor for women transitioning into STEM majors in Montana two-year colleges

Science.gov (United States)

Jakes, Penny Jane

The purpose of this non-experimental, descriptive, quantitative study was to describe the impact high school dual enrollment coursework has had on initial enrollment of women with STEM majors in Montana two-year colleges. The study was designed to find whether or not differences existed for access (initial enrollment), persistence (to third semester), and success (associate's degree, certificate, or transfer to a four-year institution within 150% of program length). The literature review highlighted the need for studies to address the issue of few women in science, technology, engineering, and mathematics (STEM) occupations. One goal of dual enrollment in Montana is to ease transitions from high school to college, including underrepresented populations such as women in STEM fields. The scope of this study was to collect, organize, and interpret data to describe the effect of that effort for women enrolling in STEM majors at two-year colleges in Montana. Baseline information established the demographics of young women who participated in dual enrollment in Montana high schools during 2007-2009. Data analysis described results using attributes of gender, dual enrollment, access, persistence, and success for those enrolled in STEM fields. Results indicated more young women than young men take advantage of dual enrollment in high school and more women than men with dual-enrollment credit initially enroll in college. More men than women major in a STEM field and more men persist and graduate within the STEM fields. Data indicated that 221 students enrolled in a Montana two-year college with DE/DC credit during 2007-2009. Of those, eight women chose STEM majors, six persisted to the third semester, and two completed. It is recommended that a mixed-methods study be conducted to give a deeper level of understanding for enrollment trends and career choice. Longitudinal studies should also be conducted as dual enrollment grows within the state of Montana. Further studies

This is a prospective comparison of weekly cisplatin to weekly paclitaxel as concurrent chemotherapy with standard radiotherapy for locally advanced cervical carcinoma. Between May 2000 and May 2004, 31 women with FIGO stage IB2-IVA cervical cancer or with postsurgical pelvic recurrence were enrolled into this phase II study and randomized to receive on a weekly basis either 40 mg/m 2 Cisplatin (group I; 16 patients) or 50 mg/m 2 paclitaxel (group II; 15 patients) concurrently with radiotherapy. Median total dose to point A was 74 Gy (range: 66-92 Gy) for group I and 66 Gy (range: 40-98 Gy) for group II. Median follow-up time was 46 months. Patient and tumor characteristics were similar in both groups. The mean number of chemotherapy cycles was also comparable with 87% and 80% of patients receiving at least 4 doses in groups I and II, respectively. Seven patients (44%) of group I and 8 patients (53%) of group II developed tumor recurrence. The Median Survival time was not reached for Group I and 53 months for group II. The proportion of patients surviving at 2 and 5 years was 78% and 54% for group I and 73% and 43% for group II respectively. This small prospective study shows that weekly paclitaxel does not provide any clinical advantage over weekly cisplatin for concurrent chemoradiation for advanced carcinoma of the cervix

2012-01-01

Objective: To evaluate the safety of cetuximab combined with intensity-modulated radiotherapy (IMRT) plus concurrent cisplatin chemotherapy in locoregionally advanced nasopharyngeal carcinoma (NPC) in a Chinese multicenter clinical study. Methods: From July 2008 to April 2009, 100 Patients with primary stage III- IV b non-keratinizing NPC were enrolled. The planned dose of IMRT to gross tumor volume and positive cervical lymph nodes was 66.0-75.9 Gy and 60-70 Gy in 30-33 fractions. Cisplatin (80 mg/m 2 , q3 week (w)) and cetuximab (400 mg/m 2 one w before radiation, and then 250 mg/m 2 per w) were given concurrently. The adverse events (AEs) were graded according to common terminology criteria for adverse events v3.0. Results: The compliance of the entire group of patient was satisfactory. Actual median dose to gross tumor volume was 69.96 Gy, and the median dose to positive cervical lymph nodes was 68 Gy. Median dose of cisplatin was 133 mg, median first-dose of cetuximab was 690 mg, and median weekly dose was 410 mg. AEs were well tolerated and manageable, mainly consisting of acneiform skin eruptions,dermatitis and mucositis. Grade 4 mucositis was observed in 2% of the patients and no other grade 4 AEs were observed. Conclusions: The combined treatment modality of IMRT + concurrent chemotherapy + cetuximab in loco-regionally advanced NPC is well tolerated. (authors)

Full Text Available Esther Mugweni,1 Stephen Pearson,2 Mayeh Omar2 1UCL Department of Infection and Population Health, University College London, London, 2The Nuffield Centre for International Health and Development, University of Leeds, Leeds, UK Background: Concurrent sexual partnerships play a key role in sustaining the HIV epidemic in Zimbabwe. Married couples are at an increased risk of contracting HIV from sexual networks produced by concurrent sexual partnerships. Addressing these partnerships is an international HIV prevention priority. Methods: Our qualitative study presents the socioeconomic factors that contribute to the occurrence of concurrent sexual partnerships among married people in Zimbabwe. We conducted 36 in-depth interviews and four focus group discussions with married men and women in Zimbabwe in 2008 to understand the organizations of concurrent sexual partnerships. Data were analyzed using framework analysis. Results: Our study indicates that relationship dissatisfaction played a key role in the engagement of concurrent sexual partnerships. Depending on the source of the dissatisfaction, there were four possible types of concurrent sexual relationships that were formed: sex worker, casual partner, regular girlfriend or informal polygyny which was referred to as “small house”. These relationships had different levels of intimacy, which had a bearing on practicing safer sex. Participants described three characteristics of hegemonic masculinity that contributed to the sources of dissatisfaction leading to concurrent sexual activity. Similarly, various aspects of emphasized femininity were described as creating opportunities for the occurrence of concurrent sexual relationships. Economic status was also listed as a factor that contributed to the occurrence of concurrent sexual partnerships. Conclusion: Marital dissatisfaction was indicated as a contributing factor to the occurrence of concurrent sexual relationships. There were several

Race, class and gender in engineering education: A quantitative investigation of first year enrollment

Science.gov (United States)

Phillips, Canek Moises Luna

Research explanations for the disparity across both race and gender in engineering education has typically relied on a deficit model, whereby women and people of color lack the requisite knowledge or psychological characteristics that Whites and men have to become engineers in sufficient numbers. Instead of using a deficit model approach to explain gender and race disparity, in the three studies conducted for this dissertation, I approach gender and race disparity as the result of processes of segregation linked to the historic and on-going perpetuation of systemic sources of oppression in the United States. In the first study, I investigate the relationship between the odds ratios of women and men enrolled in first year US engineering programs and institutional characteristics. To do this, I employ linear regression to study data from the American Society of Engineering Education (ASEE) and the National Center for Education Statistics (NCES) to quantify relationships between odds ratios and institutional characteristics. Results of the linear regression models showed significant relationships between the cost of universities and university selectivity and the odds ratios of women choosing engineering. I theorize how the results could be related to the operation of occupational segregation in engineering, particularly how class-based markers have been historically used by women to overcome gender-based segregation in engineering. In the second study, I examine longitudinal patterns of race, gender, and intersectional combinations of race and gender in enrollments of students in first year engineering programs across the United States (US). Using enrollment data from the American Society of Engineering Education and California Post-Secondary Education Commission, I construct measures of segregation to study how trends in the disparity of students by race could be related to increases in public school segregation nationally over the past 25 years. I found that as

Limited information exists on adults ≥50 years receiving HIV care in sub-Saharan Africa. Using routinely-collected longitudinal patient-level data among 391,111 adults ≥15 years enrolling in HIV care from January 2005-December 2010 and 184,689 initiating ART, we compared characteristics and outcomes between older (≥50 years) and younger adults at 199 clinics in Kenya, Mozambique, Rwanda, and Tanzania. We calculated proportions over time of newly enrolled and active adults receiving HIV care and initiating ART who were ≥50 years; cumulative incidence of loss to follow-up (LTF) and recorded death one year after enrollment and ART initiation, and CD4+ response following ART initiation. From 2005-2010, the percentage of adults ≥50 years newly enrolled in HIV care remained stable at 10%, while the percentage of adults ≥50 years newly initiating ART (10% [2005]-12% [2010]), active in follow-up (10% [2005]-14% (2010]), and active on ART (10% [2005]-16% [2010]) significantly increased. One year after enrollment, older patients had significantly lower incidence of LTF (33.1% vs. 32.6%[40-49 years], 40.5%[25-39 years], and 56.3%[15-24 years]; p-valueages, with older adults experiencing less LTF than younger adults. Among 85,763 ART patients with baseline and follow-up CD4+ counts, adjusted average 12-month CD4+ response for older adults was 20.6 cells/mm3 lower than for adults 25-39 years of age (95% CI: 17.1-24.1). The proportion of patients who are ≥50 years has increased over time and been driven by aging of the existing patient population. Older patients experienced less LTF, higher recorded mortality and less robust CD4+ response after ART initiation. Increased programmatic attention on older adults receiving HIV care in sub-Saharan Africa is warranted.

Expanding gerontology enrollments: successful results of an innovative outreach program.

Science.gov (United States)

Reynolds, Sandra L; Haley, William E; Hyer, Kathryn

2007-01-01

As state budget allocations for higher education decrease, "specialty" programs such as gerontology must continually demonstrate their productivity. State and private universities increasingly rely on student credit hours (SCH) or tuition generated, which is making it difficult for many gerontology programs to expand. The School of Aging Studies at the University of South Florida has achieved a 236% increase in annual SCH productivity over the past 5 years by methods including qualifying courses for university liberal arts requirements, and designing and cross-listing interdisciplinary courses. This increased productivity has supported program expansion and led to beneficial outreach to students from diverse majors.

Merchant, Shaila; Hameed, Morad; Melck, Adrienne

2011-12-01

Interest in general surgery has declined, and lack of adequate accommodation for pregnancy and parenting may be a deterrent. We explored resident experiences with these issues within a single general surgery program. We surveyed residents enrolled in the University of British Columbia general surgery program from 1997 to 2009 using a Web-based survey tool. Information regarding demographics, pregnancy, postpartum issues and issues pertaining to maternity/parenting policies was obtained. We used the Student t test, Z test and Fisher exact test for statistical comparisons. Of the 81 residents surveyed, 53 responded (65% response rate). There were fewer pregnancies during residency among female residents than among partners of male residents (PMRs; 9 pregnancies for 6 of 25 residents v. 23 pregnancies for 15 of 28 PMRs, p = 0.002). One of 9 pregnancies among female residents and 5 of 23 among PMRs ended in miscarriage (p > 0.99). Female residents and PMRs reported pregnancy-related complications with equal frequency. All female residents breastfed for at least 6 months; however, 67% (4 of 6) felt their resident role prevented them from breastfeeding as long as they would have liked. Most (5 of 6, 83%) pursued a graduate degree or research during their "maternity leave." More than 50% of residents reported that their own workload increased because of a colleague's pregnancy. Many (36 of 53, 68%) were unaware of the existence of any maternity/parenting policy, and most were in favour of instituting such a policy. Resident mothers do not breastfeed for the desired duration, and precluding factors must be explored. Contingency plans are needed so colleagues are not overburdened when pregnant residents cannot perform clinical duties. General surgery programs must have a formal policy addressing these issues.

Li Ning; Jin Jing; Li Yexiong

2012-01-01

Objective: To determine the maximal tolerated dose and the dose-limiting toxicity of hydroxycamptothecine (HCPT) concurrently combined with three-dimensional conformal radiotherapy (3DCRT) for unresectable or locally relapsed rectal cancer. Methods: Twenty-two patients with rectal cancer were enrolled into phase I study between 2004 -2007. HCPT was intravenously administered concurrently with 3DCRT weekly, dose given from 6, 8, 10 mg/m 2 or twice a week, dose given from 4, 6, 8, 10 mg/m 2 , respectively. Total radiation dose of 50 Gy was delivered to the whole pelvis at a fraction of 2 Gy per day for 5 weeks, with 10 - 16 Gy subsequent boost to tumor area. Dose-limiting toxicities (DLT) were defined as grade 3 or higher non-hematologic toxicity or grade 4 hematologic toxicity. Results: In the twice a week group, DLTs of grade 3 diarrhea were observed in 2 patient treated at dose of 6 mg/m 2 . In the weekly group, DLTs of grade 3 diarrhea and radiation-induced dermatitis were observed in I patient at dose of 8 mg/m 2 , and were not observed in the next 3 patients at the same dose level. However, at dose of 10 mg/m 2 , 2 patients had grade 3 diarrhea or nausea. The 5-year overall survival rate was 23% and the median survival time was 18 months. Conclusions: HCPT given concurrently with 3DCRT is safe and tolerable for patients with unresectable or locally relapsed rectal cancer. Either 8 mg/m 2 weekly or 4 mg/m 2 twice a week can be recommended for further study. The dose-limiting toxicities are grade 3 diarrhea, nausea and radiation-induced dermatitis. (authors)

Purpose: The goal of this phase 1 trial was to determine the maximum tolerated dose (MTD) of concurrent capecitabine, bevacizumab, and erlotinib with preoperative radiation therapy for rectal cancer. Methods and Materials: Patients with clinical stage II to III rectal adenocarcinoma, within 12 cm from the anal verge, were treated in 4 escalating dose levels, using the continual reassessment method. Patients received preoperative radiation therapy with concurrent bevacizumab (5 mg/kg intravenously every 2 weeks), erlotinib, and capecitabine. Capecitabine dose was increased from 650 mg/m{sup 2} to 825 mg/m{sup 2} orally twice daily on the days of radiation therapy; erlotinib dose was increased from 50 mg orally daily in weeks 1 to 3, to 50 mg daily in weeks 1 to 6, to 100 mg daily in weeks 1 to 6. Patients underwent surgery at least 9 weeks after the last dose of bevacizumab. Results: A total of 19 patients were enrolled, and 18 patients were considered evaluable. No patient had grade 4 acute toxicity, and 1 patient had grade 3 acute toxicity (hypertension). The MTD was not reached. All 18 evaluable patients underwent surgery, with low anterior resection in 7 (39%), proctectomy with coloanal anastomosis in 4 patients (22%), posterior pelvic exenteration in 1 (6%), and abdominoperineal resection in 6 (33%). Of the 18 patients, 8 (44%) had pathologic complete response, and 1 had complete response of the primary tumor with positive nodes. Three patients (17%) had grade 3 postoperative complications (ileus, small bowel obstruction, and infection). With a median follow-up of 34 months, 1 patient developed distant metastasis, and no patient had local recurrence or died. The 3-year disease-free survival was 94%. Conclusions: The combination of preoperative radiation therapy with concurrent capecitabine, bevacizumab, and erlotinib was well tolerated. The pathologic complete response rate appears promising and may warrant further investigation.

To determine the relationship between physical activity (PA) and health-related quality of life among university employees who enrolled in a worksite wellness program (WWP). The study was an interim analysis of data collected in a WWP. The sample consisted of 64 participants who completed 12- and 26-week follow-up appointments. Self-reported anxiety days significantly decreased from baseline to week 12. There were positive trends in self-rated health, vitality days, and summative unhealthy days from baseline to week 26. Among those with a self-reported history of hypertension (HTN), there was an inverse correlation between PA and summative physically and mentally unhealthy days at week 12. Among participants in this WWP with HTN, as PA increased there was a significant decrease in summative physically and mentally unhealthy days at week 12.

Balance function has been reported to be worse in ADHD children than in their normal peers. The present study hypothesized that an improvement in balance could result in better cognitive performance in children with ADHD and concurrent vestibular impairment. This study was designed to evaluate the effects of comprehensive vestibular rehabilitation therapy on the cognitive performance of children with combined ADHD and concurrent vestibular impairment. Subject were 54 children with combined ADHD. Those with severe vestibular impairment (n=33) were randomly assigned to two groups that were matched for age. A rehabilitation program comprising overall balance and gate, postural stability, and eye movement exercises was assigned to the intervention group. Subjects in the control group received no intervention for the same time period. Intervention was administered twice weekly for 12 weeks. Choice reaction time (CRT) and spatial working memory (SWM) subtypes of the Cambridge Neuropsychological Test Automated Battery (CANTAB) were completed pre- and post-intervention to determine the effects of vestibular rehabilitation on the cognitive performance of the subjects with ADHD and concurrent vestibular impairment. ANCOVA was used to compare the test results of the intervention and control group post-test. The percentage of correct trial scores for the CRT achieved by the intervention group post-test increased significantly compared to those of the control group (p=0.029). The CRT mean latency scores were significantly prolonged in the intervention group following intervention (p=0.007) compared to the control group. No significant change was found in spatial functioning of the subjects with ADHD following 12 weeks of intervention (p>0.05). The study highlights the effect of vestibular rehabilitation on the cognitive performance of children with combined ADHD and concurrent vestibular disorder. The findings indicate that attention can be affected by early vestibular

Purpose: To determine the maximum tolerated dose and the dose-limiting toxicity of capecitabine with standard radiotherapy (RT) as adjuvant treatment in patients with rectal cancer. Methods and Materials: Patients with Stage II/III rectal cancer after surgery were eligible. Total RT dose was delivered as DT 50 Gy in fractions of 2.0 Gy/day for 5 weeks to the pelvic area. Capecitabine was administered concurrently with RT in escalating doses, twice daily with a 12-h interval, for two cycles of 14 days separated by a 7-day rest. Dose-limiting toxicity included Grade 3 or Grade 4 hematologic and nonhematologic toxicity. Results: Twenty-four patients were enrolled at the following dose levels: 1,000 (3 patients), 1,200 (3 patients), 1,400 (3 patients), 1,500 (3 patients), 1,600 (6 patients), and 1,700 mg/m 2 /day (6 patients). Dose-limiting toxicity was observed in 1 patient at 1,600 mg/m 2 /day (Grade 3 diarrhea) and in 2 patients at 1,700 mg/m 2 /day (1 patient had Grade 3 and 1 Grade 4 diarrhea). Conclusion: The maximum tolerated dose (MTD) of capecitabine given concurrently with RT was 1,600 mg/m 2 , daily from the 1st to the 14th day, with a 7-day rest, for two cycles

Tremoulet, P. C.

The author describes a number of maintenance improvements in the Fiber Optic Cable System (FOCS). They were achieved during a production phase pilot concurrent engineering program. Listed in order of importance (saved maintenance time and material) by maintenance level, they are: (1) organizational level: improved fiber optic converter (FOC) BITE; (2) Intermediate level: reduced FOC adjustments from 20 to 2; partitioned FOC into electrical and optical parts; developed cost-effective fault isolation test points and test using standard test equipment; improved FOC chassis to have lower mean time to repair; and (3) depot level: revised test requirements documents (TRDs) for common automatic test equipment and incorporated ATE testability into circuit and assemblies and application-specific integrated circuits. These improvements met this contract's tailored logistics MIL-STD 1388-1A requirements of monitoring the design for supportability and determining the most effective support equipment. Important logistics lessons learned while accomplishing these maintainability and supportability improvements on the pilot concurrent engineering program are also discussed.

Purpose: To investigate the safety and efficacy of concurrent vinorelbine and thoracic radiotherapy in elderly patients with locally advanced non-small-cell lung cancer (NSCLC). Methods and Materials: Eligible patients were 71 years of age or older with unresectable Stage III NSCLC. Patients were treated with thoracic radiotherapy (60 Gy) and concurrent vinorelbine (20 mg/m{sup 2} in Level 1 and 25 mg/m{sup 2} in Level 2) on Days 1 and 8 every 3 weeks for two cycles, followed by adjuvant vinorelbine (25 mg/m{sup 2}) on Days 1 and 8 every 3 weeks for two cycles. Results: Four patients were enrolled at Level 1. One patient experienced Grade 3 febrile neutropenia at Level 1 and the dose was escalated to Level 2. At Level 2, 2 of 6 patients experienced dose-limiting toxicities (Grade 4 neutropenia in 1 patient and Grade 3 infection in another). Three of 6 patients developed late Grade 2 or 3 pneumonitis. Therefore, the dose was de-escalated to Level 1. An additional 6 patients were enrolled at Level 1, 4 of whom experienced dose-limiting toxicities (incomplete radiotherapy because of Grade 2 pneumonitis in 1 patient and Grade 3 infection in 1, Grade 3 febrile neutropenia in 1, and Grade 3 esophagitis in 1). Moreover, late Grade 3 pneumothorax and Grade 5 pneumonitis occurred in 1 and 1 patient, respectively. Overall, Grade 2, 3 and 5 pneumonitis occurred in 3, 3, and 1 among 16 patients, respectively. Conclusions: Concurrent vinorelbine and thoracic radiotherapy resulted in a high incidence of severe pneumonitis when the standard dose of this agent was used for elderly patients. We therefore recommend caution in the use of this regimen and schedule for elderly patients.

To investigate factors influencing response and survival for patients with squamous cell cancer of the esophagus. Forty-nine patients with squamous cell cancer of the esophagus, classified by guidelines for the clinical and pathologic studies on carcinoma of the esophagus published by the Japanese Society for Esophageal Disease, were treated by concurrent chemoradiotherapy using chemotherapy consisting of cisplatin and 5-fluorouracil with definitive irradiation of 60 Gy concurrently. Endoscopic findings and biopsy were used for evaluating the response. Nurse charts recording patient's feeding status were adopted to estimate severity of dysphagia. Complete response (CR) rate was 69.4%, median survival time (MST) was 12.3 months, and median local failure-free survival time 7.3 months. Patients in early stage (= 32.4 months, 20.4 months, 20.4 months, 15.7 months, respectively). Patients in A3 stage were often suffered from severe dysphagia both before and after treatment (81.5%, 70.4%), respectively. Concurrent chemoradiotherapy was effective treatment for esophageal cancer. Degree of dysphagia was considered to be a good prognosticator of patients' survival. (author)

Receipt of preventive dental care among special-needs children enrolled in Medicaid: a crisis in need of attention.

Science.gov (United States)

Mitchell, Jean M; Gaskin, Darrell J

2008-10-01

Although not widely recognized, tooth decay is the most common childhood chronic disease among children ages five to seventeen. Despite higher rates of dental caries and greater needs, low-income minority children enrolled in Medicaid are more likely to go untreated relative to their higher income counterparts. No research has examined this issue for children with special needs. We analyzed Medicaid enrollment and claims data for special-needs children enrolled in the District of Columbia Medicaid program to evaluate receipt of recommended preventive dental care. Use of preventive dental care is abysmally low and has declined over time. Enrollment in managed care rather than fee for service improves the likelihood that special-needs children receive recommended preventive dental services, whereas residing farther from the Metro is an impediment to receipt of dental care.

Objective: A phase I study was conducted to determine the maximal tolerated dose (MTD) and the dose-limiting toxicity (DLT) of chemotherapy of oral doxifluridine (5-dFUR) and leucovorin with concurrent standard radiotherapy(RT) as adjuvant treatment in patients with rectal cancer. Methods: Patients aged 18-75 years old, Kamofsky scored ≥70%, stage II/III rectal cancer after curative surgery were eligible. Total RT dose was delivered as DT 50 Gy in the fraction of 2.0 Gy per day for 5 weeks to the pelvic area. 5-dFUR was administered concurrently with radiotherapy in escalating doses, and oral leucovorin was administered in a fixed dose of 30 mg/(m 2 ·d), both 3 times daily, from the 1 st day of RT to the last day. The DLTs included grade 3 or grade 4 hematologic and nonhematologie toxicity. Results: From Aug. 2005 to Mar. 2007, 16 patients were enrolled at the following dose levels: 450 mg/(m 2 ·d) (3 patients), 550 mg/(m 2 ·d) (6 patients) and 650 mg/(m 2 ·d) (7 patients). Diarrhea, neutropenia and nausea/vomit were the most common side effects although all neutropenia was less grade 3. The DLT was observed in 1 patient at 550 mg/(m 2 ·d) (grade 4 diarrhea), but none in the following 3 patients at the same dose level. At 650 mg/(m 2 ·d) level, the first patient quitted the study due to a severe abdominal cramp pain in the 3rd week of RT. In the following 3 enrolled patients, one suffered grade 3 abdominal cramp pain, diarrhea, fatigue, nausea/vomit and grade 2 neutropenia and fever. Grade 3 diarrhea was also observed in all the additional 3 patients at 650 mg/(m 2 ·d) dose level. So the dose escalation was ended up to 650 mg/(m 2 ·d). Four of 16 patients didn't complete the scheduled concurrent chemoradiotherapy due to severe side effects, including 1 at 550 mg/(m 2 ·d) dose level, and 3 at 650 mg/(m 2 ·d). The DLTs were observed as grade 3/4 diarrhea, grade 3 abdominal cramp pain, fatigue and nausea/vomit. Conclusions: Diarrhea is the most common and

The goal of this project is to provide tools to assess the correctness of parallel programs written using hybrid parallelism. There is a dire lack of both theoretical and engineering know-how in the area of finding bugs in hybrid or large scale parallel programs, which our research aims to change. In the project we have demonstrated novel approaches in several areas: 1. Low overhead automated and precise detection of concurrency bugs at scale. 2. Using low overhead bug detection tools to guide speculative program transformations for performance. 3. Techniques to reduce the concurrency required to reproduce a bug using partial program restart/replay. 4. Techniques to provide reproducible execution of floating point programs. 5. Techniques for tuning the floating point precision used in codes.

Short-term Mobility and Increased Partnership Concurrency among Men in Zimbabwe.

Directory of Open Access Journals (Sweden)

Susan Cassels

Full Text Available Migration has long been understood as an underlying factor for HIV transmission, and sexual partner concurrency has been increasingly studied as an important component of HIV transmission dynamics. However, less work has examined the role of short-term mobility in sexual partner concurrency using a network approach. Short-term mobility may be a risk for HIV for the migrant's partner as well either through the partner's risk behaviors while the migrant is away, such as the partner having additional partners, or via exposure to the return migrant.Using data from the 2010-11 Zimbabwe Demographic and Health Survey, weighted generalized linear regression models were used to investigate the associations between short-term mobility and partnership concurrency at the individual and partnership levels.At the individual level, we find strong evidence of an association between short-term mobility and concurrency. Men who traveled were more likely to have concurrent partnerships compared to men who did not travel and the relationship was non-linear: each trip was associated with a 2% higher probability of concurrency, with a diminishing risk at 60 trips (p<0.001. At the partnership level, short-term mobility by the male only or both partners was associated with male concurrency. Couples in which the female only traveled exhibited less male concurrency.Short-term mobility has the ability to impact population-level transmission dynamics by facilitating partnership concurrency and thus onward HIV transmission. Short-term migrants may be an important population to target for HIV testing, treatment, or social and behavioral interventions to prevent the spread of HIV.

Concurrent negotiation and coordination for grid resource coallocation.

Bolstering resource coallocation is essential for realizing the Grid vision, because computationally intensive applications often require multiple computing resources from different administrative domains. Given that resource providers and consumers may have different requirements, successfully obtaining commitments through concurrent negotiations with multiple resource providers to simultaneously access several resources is a very challenging task for consumers. The impetus of this paper is that it is one of the earliest works that consider a concurrent negotiation mechanism for Grid resource coallocation. The concurrent negotiation mechanism is designed for 1) managing (de)commitment of contracts through one-to-many negotiations and 2) coordination of multiple concurrent one-to-many negotiations between a consumer and multiple resource providers. The novel contributions of this paper are devising 1) a utility-oriented coordination (UOC) strategy, 2) three classes of commitment management strategies (CMSs) for concurrent negotiation, and 3) the negotiation protocols of consumers and providers. Implementing these ideas in a testbed, three series of experiments were carried out in a variety of settings to compare the following: 1) the CMSs in this paper with the work of others in a single one-to-many negotiation environment for one resource where decommitment is allowed for both provider and consumer agents; 2) the performance of the three classes of CMSs in different resource market types; and 3) the UOC strategy with the work of others [e.g., the patient coordination strategy (PCS )] for coordinating multiple concurrent negotiations. Empirical results show the following: 1) the UOC strategy achieved higher utility, faster negotiation speed, and higher success rates than PCS for different resource market types; and 2) the CMS in this paper achieved higher final utility than the CMS in other works. Additionally, the properties of the three classes of CMSs in

Purpose: Proton therapy has been shown to reduce radiation dose to organs at risk (OAR) and could be used to safely escalate the radiation dose. We analyzed outcomes in a group of phase 2 study patients treated with dose-escalated proton therapy with concurrent chemotherapy for stage 3 non-small cell lung cancer (NSCLC). Methods and Materials: From 2009 through 2013, LU02, a phase 2 trial of proton therapy delivering 74 to 80 Gy at 2 Gy/fraction with concurrent chemotherapy for stage 3 NSCLC, was opened to accrual at our institution. Due to slow accrual and competing trials, the study was closed after just 14 patients (stage IIIA, 9 patients; stage IIIB, 5 patients) were accrued over 4 years. During that same time period, 55 additional stage III patients were treated with high-dose proton therapy, including 7 in multi-institutional proton clinical trials, 4 not enrolled due to physician preference, and 44 who were ineligible based on strict entry criteria. An unknown number of patients were ineligible for enrollment due to insurance coverage issues and thus were treated with photon radiation. Median follow-up of surviving patients was 52 months. Results: Two-year overall survival and progression-free survival rates were 57% and 25%, respectively. Median lengths of overall survival and progression-free survival were 33 months and 14 months, respectively. There were no acute grade 3 toxicities related to proton therapy. Late grade 3 gastrointestinal toxicity and pulmonary toxicity each occurred in 1 patient. Conclusions: Dose-escalated proton therapy with concurrent chemotherapy was well tolerated with encouraging results among a small cohort of patients. Unfortunately, single-institution proton studies may be difficult to accrue and consideration for pragmatic and/or multicenter trial design should be considered when developing future proton clinical trials.

Object oriented distributed programming: studies and proposals

International Nuclear Information System (INIS)

Guerraoui, Rachid

1992-01-01

This thesis contributes to the investigation of the object concept in distributed programming. Henceforth, this programming style has become a reality in the computer science world, since it allows to increase of the availability of applications and to decrease their execution time. Nevertheless, designing a distributed application is a hard task: the various abstraction levels that must be considered hinder the software reusability and maintenance, while errors and concurrent accesses are often sources of executions incoherence. The object concept improves the software modularity, and raises the computing abstraction level. Integrating distribution related aspects into the object model brings up the issues of expressing the concurrency and maintaining the coherency. The investigation of these problems in this thesis has been guided by a major concern for the preservation of the intrinsic properties of object-orientation, and the orthogonality of the solutions given. The main contributions of the thesis are: (i) the classification, regarding modularity, of the different design alternatives for object-oriented concurrent languages; (ii) the evaluation of various transactional mechanisms in object-based concurrent languages, and the design of an atomic asynchronous communication protocol named ACS; (iii) the definition of a transaction-based object-oriented concurrent language called KAROS; (iv) the implementation of a modular framework which allows to combine in a same application, various concurrency control and error recovery mechanisms; (v) the identification of a formal property, named general atomicity, which constitutes a correctness criteria for atomic objects specifications.

Data refinement for true concurrency

Directory of Open Access Journals (Sweden)

Brijesh Dongol

2013-05-01

Full Text Available The majority of modern systems exhibit sophisticated concurrent behaviour, where several system components modify and observe the system state with fine-grained atomicity. Many systems (e.g., multi-core processors, real-time controllers also exhibit truly concurrent behaviour, where multiple events can occur simultaneously. This paper presents data refinement defined in terms of an interval-based framework, which includes high-level operators that capture non-deterministic expression evaluation. By modifying the type of an interval, our theory may be specialised to cover data refinement of both discrete and continuous systems. We present an interval-based encoding of forward simulation, then prove that our forward simulation rule is sound with respect to our data refinement definition. A number of rules for decomposing forward simulation proofs over both sequential and parallel composition are developed.

Women in sub-Saharan Africa are a priority population for evaluation of new biomedical HIV-1 prevention strategies. Antiretroviral pre-exposure prophylaxis is a promising prevention approach; however, clinical trials among young women using daily or coitally-dependent products have found low adherence. Antiretroviral-containing vaginal microbicide rings, which release medication over a month or longer, may reduce these adherence challenges. ASPIRE (A Study to Prevent Infection with a Ring for Extended Use) is a phase III, randomized, double-blind, placebo-controlled trial testing the safety and effectiveness of a vaginal ring containing the non-nucleoside reverse transcriptase inhibitor dapivirine for prevention of HIV-1 infection. We describe the baseline characteristics of African women enrolled in the ASPIRE trial. Between August 2012 and June 2014, 5516 women were screened and 2629 HIV-1 seronegative women between 18-45 years of age were enrolled from 15 research sites in Malawi, South Africa, Uganda, and Zimbabwe. The median age was 26 years (IQR 22-31) and the majority (59%) were unmarried. Nearly 100% of participants reported having a primary sex partner in the prior three months but 43% did not know the HIV-1 status of their primary partner; 17% reported additional concurrent partners. Nearly two-thirds (64%) reported having disclosed to primary partners about planned vaginal ring use in the trial. Sexually transmitted infections were prevalent: 12% had Chlamydia trachomatis, 7% Trichomonas vaginalis, 4% Neisseria gonorrhoeae, and 1% syphilis. African HIV-1 seronegative women at risk of HIV -1 infection were successfully enrolled into a phase III trial of dapivirine vaginal ring for HIV-1 prevention.

Gross, C P; Krumholz, H M

To determine the relationship between managed care market activity and cancer trial enrollment. Trial participant data were obtained from the National Cancer Institute. Participants in cooperative group trials of breast, colorectal, lung, or prostate cancer during the years 1996 through 2001 were assigned to counties based on their zip code of residence. Linear regression was used to determine the relationship between county enrollment rate and two measures of county managed care activity (penetration and index of competition [IOC]), adjusting for other county characteristics. In bivariate analysis, there was a strong inverse correlation between trial enrollment rate and IOC (r = -0.23; P penetration, proportion uninsured, and other county characteristics. Counties in the lowest quartile of managed care penetration tended to have lower enrollment rates than the remaining counties (r = -0.05; P = .048), while counties in the second, third, and fourth quartiles of penetration all had similar enrollment rates to one another. Cancer trial enrollment rates were suboptimal across all counties, and counties with higher levels of managed care competition had significantly lower enrollment rates. The relationship between managed care penetration and trial enrollment was less consistent. Future efforts to enhance trial participation should address the potential negative influence of market factors.

Concurrent variable-interval variable-ratio schedules in a dynamic choice environment.

Bell, Matthew C; Baum, William M

2017-11-01

Most studies of operant choice have focused on presenting subjects with a fixed pair of schedules across many experimental sessions. Using these methods, studies of concurrent variable- interval variable-ratio schedules helped to evaluate theories of choice. More recently, a growing literature has focused on dynamic choice behavior. Those dynamic choice studies have analyzed behavior on a number of different time scales using concurrent variable-interval schedules. Following the dynamic choice approach, the present experiment examined performance on concurrent variable-interval variable-ratio schedules in a rapidly changing environment. Our objectives were to compare performance on concurrent variable-interval variable-ratio schedules with extant data on concurrent variable-interval variable-interval schedules using a dynamic choice procedure and to extend earlier work on concurrent variable-interval variable-ratio schedules. We analyzed performances at different time scales, finding strong similarities between concurrent variable-interval variable-interval and concurrent variable-interval variable- ratio performance within dynamic choice procedures. Time-based measures revealed almost identical performance in the two procedures compared with response-based measures, supporting the view that choice is best understood as time allocation. Performance at the smaller time scale of visits accorded with the tendency seen in earlier research toward developing a pattern of strong preference for and long visits to the richer alternative paired with brief "samples" at the leaner alternative ("fix and sample"). © 2017 Society for the Experimental Analysis of Behavior.

2008-01-01

Public health is an important component of veterinary medicine. In the last 10 years, there has been growing recognition of the need to increase the number of veterinarians trained in public health. The Center for Food Security and Public Health (CFSPH) at Iowa State University (ISU), College of Veterinary Medicine, received a grant from the Centers for Disease Control and Prevention (CDC) to support veterinarians working at CFSPH while pursuing the Master of Public Health degree. CFSPH and ISU administrators worked with the University of Iowa (UI) College of Public Health to establish three cooperative programs for veterinarians to earn the MPH degree. This article describes how these programs were developed and how they operate. (1) Between 2002 and 2005, CFSPH used funds provided by the CDC to support 15 veterinarians as they worked for CFSPH and toward the MPH degree. As the program grew, distance-education methods such as the Internet, Polycom videoconferencing, and the Iowa Communications Network (ICN) were incorporated. (2) A concurrent DVM/MPH degree is now offered; students can complete both degrees in four years. As of January 2008, three students have received their DVM and MPH degrees and 16 students are enrolled in the program. (3) In June 2007, the UI and ISU launched a distance MPH program for veterinarians working in private practice, industry, and government. Eight veterinarians are participating in the program, which includes two two-week, in-person summer sessions, with the remainder of the coursework taken at a distance via the Internet.

Service-Oriented Synthesis of Distributed and Concurrent Protocol Specifications

Directory of Open Access Journals (Sweden)

Jehad Al Dallal

2008-01-01

Full Text Available Several methods have been proposed for synthesizing computer communication protocol specifications from service specifications. Some protocol synthesis methods based on the finite state machine (FSM model assume that primitives in the service specifications cannot be executed simultaneously. Others either handle only controlled primitive concurrency or have tight restrictions on the applicable FSM topologies. As a result, these synthesis methods are not applicable to an interesting variety of inherently concurrent applications, such as the Internet and mobile communication systems. This paper proposes a concurrent-based protocol synthesis method that eliminates the restrictions imposed by the earlier methods. The proposed method uses a synthesis method to obtain a sequential protocol specification (P-SPEC from a given service specification (S-SPEC. The resulting P-SPEC is then remodeled to consider the concurrency behavior specified in the S-SPEC, while guaranteeing that P-SPEC provides the specified service.

Prototyping of concurrent control systems implemented in FPGA devices

CERN Document Server

Wiśniewski, Remigiusz

2017-01-01

This book focuses on prototyping aspects of concurrent control systems and their further implementation and partial reconfiguration in programmable devices. Further, it lays out a full prototyping flow for concurrent control systems. Based on a given primary specification, a system is described with an interpreted Petri net, which naturally reflects the concurrent and sequential relationships of the design. The book shows that, apart from the traditional option of static configuration of the entire system, the latest programmable devices (especially FPGAs) offer far more sophistication. Partial reconfiguration allows selected parts of the system to be replaced without having to reprogram the entire structure of the device. Approaches to dynamic and static partial reconfiguration of concurrent control systems are presented and described in detail.< The theoretical work is illustrated by examples drawn from various applications, with a milling machine and a traffic-light controller highlighted as representat...

Baines, John; The ATLAS collaboration

2016-01-01

In order to be able to make effective use of emerging hardware, where the amount of memory available to any CPU is rapidly decreasing as the core count continues to rise, ATLAS has begun a migration to a concurrent, multi-threaded software framework, known as AthenaMT. Significant progress has been made in implementing AthenaMT - we can currently run realistic Geant4 simulations on massively concurrent machines. the migration of realistic prototypes of reconstruction workflows is more difficult, given the large amounts of legacy code and the complexity and challenges of reconstruction software. These types of workflows, however, are the types that will most benefit from the memory reduction features of a multi-threaded framework. One of the challenges that we will report on in this paper is the re-design and implementation of several key asynchronous technologies whose behaviour is radically different in a concurrent environment than in a serial one, namely the management of Conditions data and the Detector D...

Purpose: Valproic acid (VPA) is an antiepileptic agent with histone deacetylase inhibitor (HDACi) activity shown to sensitize glioblastoma (GBM) cells to radiation in preclinical models. We evaluated the addition of VPA to standard radiation therapy (RT) plus temozolomide (TMZ) in patients with newly diagnosed GBM. Methods and Materials: Thirty-seven patients with newly diagnosed GBM were enrolled between July 2006 and April 2013. Patients received VPA, 25 mg/kg orally, divided into 2 daily doses concurrent with RT and TMZ. The first dose of VPA was given 1 week before the first day of RT at 10 to 15 mg/kg/day and subsequently increased up to 25 mg/kg/day over the week prior to radiation. VPA- and TMZ-related acute toxicities were evaluated using Common Toxicity Criteria version 3.0 (National Cancer Institute Cancer Therapy Evaluation Program) and Cancer Radiation Morbidity Scoring Scheme for toxicity and adverse event reporting (Radiation Therapy Oncology Group/European Organization for Research and Treatment). Results: A total of 81% of patients took VPA according to protocol. Median overall survival (OS) was 29.6 months (range: 21-63.8 months), and median progression-free survival (PFS) was 10.5 months (range: 6.8-51.2 months). OS at 6, 12, and 24 months was 97%, 86%, and 56%, respectively. PFS at 6, 12, and 24 months was 70%, 43%, and 38% respectively. The most common grade 3/4 toxicities of VPA in conjunction with RT/TMZ therapy were blood and bone marrow toxicity (32%), neurological toxicity (11%), and metabolic and laboratory toxicity (8%). Younger age and class V recursive partitioning analysis (RPA) results were significant for both OS and PFS. VPA levels were not correlated with grade 3 or 4 toxicity levels. Conclusions: Addition of VPA to concurrent RT/TMZ in patients with newly diagnosed GBM was well tolerated. Additionally, VPA may result in improved outcomes compared to historical data and merits further study.

Patterns of online student enrolment and attrition in Australian open access online education: a preliminary case study

Directory of Open Access Journals (Sweden)

Steven J Greenland

2014-02-01

Full Text Available Swinburne University of Technology has experienced tremendous growth in open access online learning and as such is typical of the many Australian institutions that have ventured into online tertiary education. While research in online education continues to expand, comparatively little investigates students’ enrolment and attrition.This research examines commencing enrolment and associated student withdrawal data, as well as performance scores from eight units forming a Marketing Major for an open access online undergraduate degree. Since data were collected over a five year period, trends and patterns within a substantial online undergraduate program can be explored.The paper discusses the challenges of analysing enrolment data. Initial findings suggest that retention strategies should be designed according to the stage students are at in their studies. Furthermore, the research informs the prioritisation and development of more effective enrolment and performance datareporting capabilities, which in turn would benefit student management and retention.http://dx.doi.org/10.5944/openpraxis.6.1.95

2014-05-01

We present Barista, an open-source framework for concurrent speech processing based on the Kaldi speech recognition toolkit and the libcppa actor library. With Barista, we aim to provide an easy-to-use, extensible framework for constructing highly customizable concurrent (and/or distributed) networks for a variety of speech processing tasks. Each Barista network specifies a flow of data between simple actors, concurrent entities communicating by message passing, modeled after Kaldi tools. Leveraging the fast and reliable concurrency and distribution mechanisms provided by libcppa, Barista lets demanding speech processing tasks, such as real-time speech recognizers and complex training workflows, to be scheduled and executed on parallel (and/or distributed) hardware. Barista is released under the Apache License v2.0.

Concurrent eruptions at Etna, Stromboli, and Vulcano: casualty or causality?

Directory of Open Access Journals (Sweden)

R. Funiciello

2008-06-01

Full Text Available Anecdotes of concurrent eruptions at Etna, Stromboli, and Vulcano (Southern Italy have persisted for more than 2000 years and volcanologists in recent and past times have hypothesized a causal link among these volcanoes. Here this hypothesis is tested. To introduce the problem and provide examples of the type of expected volcanic phenomena, narratives of the most notable examples of concurrent eruptions are provided. Then the frequency of eruptions at each individual volcano is analysed for about the last 300 years and the expected probability of concurrent eruptions is calculated to compare it to the observed probability. Results show that the occurrence of concurrent eruptions is often more frequent than a random probability, particularly for the Stromboli-Vulcano pair. These results are integrated with a statistical analysis of the earthquake catalogue to find evidence of linked seismicity in the Etnean and Aeolian areas. Results suggest a moderate incidence of non-random concurrent eruptions, but available data are temporally limited and do not allow an unequivocal identification of plausible triggers; our results, however, are the first attempt to quantify a more-than-2000-years-old curious observation and constitute a starting point for more sophisticated analyses of new data in the future. We look forward to our prediction of a moderate incidence of concurrent eruptions being confirmed or refuted with the passage of time and occurrence of new events.

2010-01-01

We report the results of the student responses to a survey aiming to determine the factors influencing the young generation in choosing a career in science and technology. The goal of the study is twofold: to identify the motives that determine students to enroll in university programs in science and technology and to engage in applied science and engineering careers and to discover the barriers that manifest at different age levels, preventing students from making such choices. The study was conducted at the Ovidius University and the "Energetic" Technical High School, both in Constanta, Romania, with samples of 257 and 106 students respectively, based on a 38 item online questionnaire. The samples selected from the student population allow for a wide range of analyses with respect to gender, family and educational background, field of study, etc. We discuss the role of the raw models, parents, educators, and we comment on ways to increase student enrollment in science and engineering.

Does personality influence job acquisition and tenure in people with severe mental illness enrolled in supported employment programs?

Science.gov (United States)

Fortin, Guillaume; Lecomte, Tania; Corbière, Marc

2017-06-01

When employment difficulties in people with severe mental illness (SMI) occur, it could be partly linked to issues not specific to SMI, such as personality traits or problems. Despite the fact that personality has a marked influence on almost every aspect of work behavior, it has scarcely been investigated in the context of employment for people with SMI. We aimed to evaluate if personality was more predictive than clinical variables of different competitive work outcomes, namely acquisition of competitive employment, delay to acquisition and job tenure. A sample of 82 people with a SMI enrolled in supported employment programs (SEP) was recruited and asked to complete various questionnaires and interviews. Statistical analyses included logistic regressions and survival analyses (Cox regressions). Prior employment, personality problems and negative symptoms are significantly related to acquisition of a competitive employment and to delay to acquisition whereas the conscientiousness personality trait was predictive of job tenure. Our results point out the relevance of personality traits and problems as predictors of work outcomes in people with SMI registered in SEP. Future studies should recruit larger samples and also investigate these links with other factors related to work outcomes.

Characteristics and outcomes among older HIV-positive adults enrolled in HIV programs in four sub-Saharan African countries.

Directory of Open Access Journals (Sweden)

Eduard Eduardo

Full Text Available Limited information exists on adults ≥50 years receiving HIV care in sub-Saharan Africa.Using routinely-collected longitudinal patient-level data among 391,111 adults ≥15 years enrolling in HIV care from January 2005-December 2010 and 184,689 initiating ART, we compared characteristics and outcomes between older (≥50 years and younger adults at 199 clinics in Kenya, Mozambique, Rwanda, and Tanzania. We calculated proportions over time of newly enrolled and active adults receiving HIV care and initiating ART who were ≥50 years; cumulative incidence of loss to follow-up (LTF and recorded death one year after enrollment and ART initiation, and CD4+ response following ART initiation.From 2005-2010, the percentage of adults ≥50 years newly enrolled in HIV care remained stable at 10%, while the percentage of adults ≥50 years newly initiating ART (10% [2005]-12% [2010], active in follow-up (10% [2005]-14% (2010], and active on ART (10% [2005]-16% [2010] significantly increased. One year after enrollment, older patients had significantly lower incidence of LTF (33.1% vs. 32.6%[40-49 years], 40.5%[25-39 years], and 56.3%[15-24 years]; p-value<0.0001, but significantly higher incidence of recorded death (6.0% vs. 5.0% [40-49 years], 4.1% [25-39 years], and 2.8% [15-24 years]; p-valve<0.0001. LTF was lower after vs. before ART initiation for all ages, with older adults experiencing less LTF than younger adults. Among 85,763 ART patients with baseline and follow-up CD4+ counts, adjusted average 12-month CD4+ response for older adults was 20.6 cells/mm3 lower than for adults 25-39 years of age (95% CI: 17.1-24.1.The proportion of patients who are ≥50 years has increased over time and been driven by aging of the existing patient population. Older patients experienced less LTF, higher recorded mortality and less robust CD4+ response after ART initiation. Increased programmatic attention on older adults receiving HIV care in sub-Saharan Africa is

Burnout is generally perceived a unified disorder with homogeneous symptomatology across people (exhaustion, cynicism, and reduced professional efficacy). However, increasing evidence points to intra-individual patterns of burnout symptoms in non-clinical samples such as students, athletes, healthy, and burned-out employees. Different burnout subtypes might therefore exist. Yet, burnout subtypes based on burnout profiles have hardly been explored in clinical patients, and the samples investigated in previous studies were rather heterogeneous including patients with various physical, psychological, and social limitations, symptoms, and disabilities. Therefore, the aim of this study is to explore burnout subtypes based on burnout profiles in clinically diagnosed burnout patients enrolled in an employee rehabilitation program, and to investigate whether the subtypes differ in depression, recovery/resources-stress balance, and sociodemographic characteristics. One hundred three patients (66 women, 37 men) with a clinical burnout diagnosis, who were enrolled in a 5 week employee rehabilitation program in two specialized psychosomatic clinics in Austria, completed a series of questionnaires including the Maslach Burnout Inventory - General Survey (MBI-GS), the Beck Depression Inventory, and the Recovery-Stress-Questionnaire for Work. Cluster analyses with the three MBI-GS subscales as clustering variables were used to identify the burnout subtypes. Subsequent multivariate/univariate analysis of variance and Pearson chi-square tests were performed to investigate differences in depression, recovery/resources-stress balance, and sociodemographic characteristics. Three different burnout subtypes were discovered: the exhausted subtype, the exhausted/cynical subtype, and the burned-out subtype. The burned-out subtype and the exhausted/cynical subtype showed both more severe depression symptoms and a worse recovery/resources-stress balance than the exhausted subtype

In Ukraine, about one-third of identified HIV-positive individuals are not connected to care. We conducted a cross-sectional survey (n = 200) among patients registered at Odessa AIDS centers in October to December 2011. Factors associated with delayed enrollment in HIV care (>3 months since positive HIV test) were evaluated using logistic regression. Among study participants (mean age 35 ± 8.2 years, 47.5% female, 42.5% reported history of injecting drugs), 55% delayed HIV care enrollment. Odds of delayed enrollment were higher for those with lower educational attainment (adjusted odds ratio [aOR]: 2.65, 95% confidence interval [CI]: 1.04-6.76), not feeling ill (aOR: 2.98, 95% CI: 1.50-5.93), or not having time to go to the AIDS center (aOR: 3.89, 95% CI: 1.39-10.89); injection drug use was not associated with delayed enrollment. Programs linking HIV-positive individuals to specialized care should address enrollment barriers and include education on HIV care benefits and case management for direct linkage to care. HIV testing and treatment should be coupled to ensure a continuum of care.

Timing is everything: international variations in historical sexual partnership concurrency and HIV prevalence.

Directory of Open Access Journals (Sweden)

Martina Morris

Full Text Available BACKGROUND: Higher prevalence of concurrent partnerships is one hypothesis for the severity of the HIV epidemic in the countries of Southern Africa. But measures of the prevalence of concurrency alone do not adequately capture the impact concurrency will have on transmission dynamics. The importance of overlap duration and coital exposure are examined here. METHODOLOGY/PRINCIPAL FINDINGS: We conducted a comparison of data from three studies of sexual behavior carried out in the early 1990s in Uganda, Thailand and the US. Using cumulative concurrency measures, the three countries appeared somewhat similar. Over 50% of both Thai and Ugandan men reported a concurrency within the last three partnerships and over 20% reported a concurrency in the last year, the corresponding rates among US men were nearly 20% for Blacks and Hispanics, and about 10% for other racial/ethnic groups. Concurrency measures that were more sensitive to overlap duration, however, showed large differences. The point prevalence of concurrency on the day of interview was over 10% among Ugandan men compared to 1% for Thai men. Ugandan concurrencies were much longer duration - a median of about two years - than either the Thai (1 day or US concurrencies (4-9 months across all groups, and involved 5-10 times more coital risk exposure with the less frequent partner. In the US, Blacks and Hispanics reported higher prevalence, longer duration and greater coital exposure than Whites, but were lower than Ugandans on nearly every measure. Together, the differences in the prevalence, duration and coital exposure of concurrent partnerships observed align with the HIV prevalence differentials seen in these populations at the time the data were collected. CONCLUSIONS/SIGNIFICANCE: There were substantial variations in the patterns of concurrent partnerships within and between populations. More long-term overlapping partnerships, with regular coital exposure, were found in populations with

a Latent Variable Path Analysis Model of Secondary Physics Enrollments in New York State.

Science.gov (United States)

Sobolewski, Stanley John

The Percentage of Enrollment in Physics (PEP) at the secondary level nationally has been approximately 20% for the past few decades. For a more scientifically literate citizenry as well as specialists to continue scientific research and development, it is desirable that more students enroll in physics. Some of the predictor variables for physics enrollment and physics achievement that have been identified previously includes a community's socioeconomic status, the availability of physics, the sex of the student, the curriculum, as well as teacher and student data. This study isolated and identified predictor variables for PEP of secondary schools in New York. Data gathered by the State Education Department for the 1990-1991 school year was used. The source of this data included surveys completed by teachers and administrators on student characteristics and school facilities. A data analysis similar to that done by Bryant (1974) was conducted to determine if the relationships between a set of predictor variables related to physics enrollment had changed in the past 20 years. Variables which were isolated included: community, facilities, teacher experience, number of type of science courses, school size and school science facilities. When these variables were isolated, latent variable path diagrams were proposed and verified by the Linear Structural Relations computer modeling program (LISREL). These diagrams differed from those developed by Bryant in that there were more manifest variables used which included achievement scores in the form of Regents exam results. Two criterion variables were used, percentage of students enrolled in physics (PEP) and percent of students enrolled passing the Regents physics exam (PPP). The first model treated school and community level variables as exogenous while the second model treated only the community level variables as exogenous. The goodness of fit indices for the models was 0.77 for the first model and 0.83 for the second

Concurrent chemoradiotherapy for cancer of head and neck is becoming more and more prevalent. In fact, it is considered to better maintain quality of life (QOL) of patients than operative treatment in terms of preserving the functions, organs, and structures, but recently I seems that it does not maintain the QOL of patients better than operative treatment because its complications after therapy disturb daily life. We previously conducted a questionnaire survey that investigated the complications experienced by patients who received concurrent chemoradiotherapy, and reported that xerostomia was markedly reduced QOL in these patients. In this study, we divided patients who were exposed to radiation in both major salivary glands into two groups: 20 patients who received a 36 Gy dose of radiation (36 Gy group) and 15 patients who underwent radiation therapy alone at a dose of 40 Gy (radiotherapy (RT) group). The gum test was conducted with the following results (mean volume of saliva): 11.2 ml in the 36 Gy group, 6.0 ml in the RT group. There was no significant difference between the 36 Gy group and RT group. Our findings suggest that there is no significant difference in the extent of salivary gland dysfunction even after chemotherapy is carried out concurrently with radiotherapy. (author)

2014-04-01

Full Text Available Objective: This study was a basic investigation of the ability of concurrent speech segregation in hearing impaired children. Concurrent segregation is one of the fundamental components of auditory scene analysis and plays an important role in speech perception. In the present study, we compared auditory late responses or ALRs between hearing impaired and normal children. Materials & Methods: Auditory late potentials in response to 12 double vowels were recorded in 10 children with moderate to severe sensory neural hearing loss and 10 normal children. Double vowels (pairs of synthetic vowels were presented concurrently and binaurally. Fundamental frequency (F0 of these vowels and the size of the difference in F0 between vowels was 100 Hz and 0.5 semitones respectively. Results: Comparing N1-P2 amplitude showed statistically significant difference in some stimuli between hearing impaired and normal children (P<0.05. This complex indexing the vowel change detection and reflecting central auditory speech representation without active client participation was decreased in hearing impaired children. Conclusion: This study showed problems in concurrent speech segregation in hearing impaired children evidenced by ALRs. This information indicated deficiencies in bottom-up processing of speech characteristics based on F0 and its differences in these children.

Purpose: A prospective phase 2 multicenter trial was performed to investigate the efficacy and safety of preoperative short-course concurrent chemoradiation therapy (CRT) followed by delayed surgery for patients with locally advanced rectal cancer. Methods and Materials: Seventy-three patients with cT3-4 rectal cancer were enrolled. Radiation therapy of 25 Gy in 5 fractions was delivered over 5 consecutive days using helical tomotherapy. Concurrent chemotherapy was administered on the same 5 days with intravenous bolus injection of 5-fluorouracil (400 mg/m{sup 2}/day) and leucovorin (20 mg/m{sup 2}/day). After 4 to 8 weeks, total mesorectal excision was performed. The primary endpoint was the pathologic downstaging (ypStage 0-I) rate, and secondary endpoints included tumor regression grade, tumor volume reduction rate, and toxicity. Results: Seventy-one patients completed the planned preoperative CRT and surgery. Downstaging occurred in 20 (28.2%) patients, including 1 (1.4%) with a pathologic complete response. Favorable tumor regression (grade 4-3) was observed in 4 (5.6%) patients, and the mean tumor volume reduction rate was 62.5 ± 21.3%. Severe (grade ≥3) treatment toxicities were reported in 27 (38%) patients from CRT until 3 months after surgery. Conclusions: Preoperative short-course concurrent CRT followed by delayed surgery for patients with locally advanced rectal cancer demonstrated poor pathologic responses compared with conventional long-course CRT, and it yielded considerable toxicities despite the use of an advanced radiation therapy technique.

Concurrent Product & Supply Chain Creation

Gubi, Ebbe

it is a structural premise. We also know that logistics costs generally are estimated 15-20% of total product costs. Accordingly, it stands to reason that a company can reduce costs, and thereby gain an edge on its competitors, by tailoring the supply chain in question to an individual product or product family; i.......e. by creating Focused Supply Chains. At the same time, customer satisfaction can be increased. As a second means to achieving a better fit between product and supply chain, the firm can deploy Design for Logistics, the discipline of considering the supply chain during product creation. The thesis sets out...... and supply chains should be created concurrently and integrated. The concept of Concurrent Product & Supply Chain Creation is introduced, and the two main components Focused Supply Chains and Design For Logistics are explained and exemplified by use of Bang & Olufsen....

Evaluate the academic experience and satisfaction of students enrolled in the dual PharmD/MBA degree program between the South Carolina College of Pharmacy and The Citadel's School of Business Administration. Compare grade point averages of students enrolled in the dual degree program with those of traditional student colleagues. A standardized satisfaction survey instrument was administered to 32 students currently enrolled in the dual PharmD/MBA degree program. Grade point averages (GPAs) in both pharmacy and business coursework were also collected for analysis. There were slightly higher percentages of both female and minority students in the dual degree program compared to the pharmacy class as a whole. Eighteen (56%) of students completed the survey, and responses were generally positive. The mean GPA of students in the dual degree program was higher than that of both pharmacy (3.37 vs 3.08, p vs 3.64, not statistically significant) students not enrolled in the dual degree program. Students enrolled in the dual degree program did better academically than their counterparts and indicated an overall high level of satisfaction with the program.

Materials and methods: Of all 50 patients who participated in the study, 5 patients with gastrointestinal (GI)-adjacent LAPC were enrolled in P-1 (50 Gy equivalent [GyE] in 25 fractions) and 5 patients with non-GI-adjacent LAPC in P-2 (70.2 GyE in 26 fractions), and 40 patients with LAPC regardless of GI-adjacency in P-3 (67.5 GyE in 25 fractions using the field-within-a-field technique). In every protocol, gemcitabine (800 mg/m 2 /week for 3 weeks) was administered concurrently. Every patient received adjuvant chemotherapy including gemcitabine after GPT within the tolerable limit. Results: The median follow-up period was 12.5 months. The scheduled GPT was feasible for all except 6 patients (12%) due to acute hematologic or GI toxicities. Grade 3 or greater late gastric ulcer and hemorrhage were seen in 5 patients (10%) in P-2 and P-3. The one-year freedom from local-progression, progression-free, and overall survival rates were 81.7%, 64.3%, and 76.8%, respectively. Conclusion: GPT was feasible and showed high efficacy. Although the number of patients and the follow-up periods are insufficient, the clinical results seem very encouraging.

As part of the implementation of the Affordable Care Act, Colorado has expanded Medicaid and also now operates its own health insurance exchange for individuals (called Connect for Health Colorado). As of early 2014, more than 300,000 Coloradans have newly enrolled in Medicaid or health insurance through Connect for Health Colorado, but there also continues to be a diverse mix of individuals in Colorado who remain eligible for but not enrolled in either private insurance or Medicaid. The Colorado Health Foundation commissioned the RAND Corporation to conduct a study to better understand why these individuals are not enrolled in health insurance coverage and to develop recommendations for how Colorado can strengthen its outreach and enrollment efforts during the next open enrollment period, which starts in November 2014. RAND conducted focus groups with uninsured and newly insured individuals across the state and interviews with local stakeholders responsible for enrollment efforts in their regions. The authors identified 11 commonly cited barriers, as well as several that were specific to certain regions or populations (such as young adults and seasonal workers). Collectively, these barriers point to a set of four priority recommendations that stakeholders in Colorado may wish to consider: (1) Support and expand localized outreach and tailored messaging; (2) Strengthen marketing and messaging to be clear, focused on health benefits of insurance (rather than politics and mandates), and actionable; (3) Improve the clarity and transparency of insurance and health care costs and enrollment procedures; and (4) Revisit the two-stage enrollment process and improve Connect for Health Colorado website navigation and technical support.

Poverty and sexual concurrency: a case study of STI risk.

This paper is about sexual concurrency, or maintaining multiple sexual partnerships that overlap in time. Sexual concurrency is a concept that is used in the field of public health to explain the spread of sexually transmitted diseases. Sexual concurrency has also been proposed as a site of intervention to reduce sexually transmitted infection (STI) rates, particularly among those populations who carry the heaviest STI burden: adolescents and African Americans. In this paper, we use ethnographic data collected from a group of African American adolescents living in Baltimore to examine the socially produced configurations of risks and relationships that are obscured by the term sexual concurrency. The data we present show the limits of this concept, and suggest that structural reforms, including improvements to education, drug treatment, and work opportunities, are necessary to reduce racial disparities in STI rates.

Characterize indications, perioperative considerations, clinical outcomes and complications for concurrent endoscopic sinus surgery (ESS) and rhinoplasty. Chronic rhinosinusitis and septal deviation with or without inferior turbinate hypertrophy independently impair patient-reported quality of life. Guidelines implore surgeons to include endoscopy to accurately evaluate patient symptoms. Complication rates parallel those of either surgery (ESS and rhinoplasty) alone and are not increased when performed concurrently. Operative time is generally longer for joint surgeries. Patient satisfaction rates are high. Concurrent functional and/or cosmetic rhinoplasty and ESS is a safe endeavor to perform in a single operative setting and most outcomes data suggest excellent patient outcomes. Additional studies that include patient-reported outcome measures are needed.

The State Children's Health Insurance Program (SCHIP) has been operating for >5 years. Policy makers are interested in the characteristics of children who have enrolled and changes in the health care needs of enrolled children as programs mature. New York State's SCHIP evolved from a similar statewide health insurance program that was developed in 1991 (Child Health Plus [CHPlus]). Understanding how current SCHIP enrollees differ from early CHPlus enrollees together with how program features changed during the period may shed light on how best to serve the evolving SCHIP population. To 1) describe changes in the characteristics of children enrolled in 1994 CHPlus and 2001 SCHIP; 2) determine if changes in the near-poor, age-eligible population during the time period could account for the evolution of enrollment; and 3) describe changes in the program during the period that could be responsible for the enrollment changes. New York State, stratified into 4 regions: New York City, New York City environs, upstate urban counties, and upstate rural counties. Retrospective telephone interviews of parents of 2 cohorts of CHPlus enrollees: 1) children who enrolled in CHPlus in 1993 to 1994 and 2) children who enrolled in New York's SCHIP in 2000 to 2001. The Current Population Survey (CPS) 1992 to 1994 and 1999 to 2001 were used to identify secular trends that could explain differences in the CHPlus and SCHIP enrollees. PROGRAM CHARACTERISTICS: 1994 CHPlus and 2001 SCHIP were similar in design, both limiting eligibility by age, family income, and insurance status. SCHIP 2001 included 1) expansion of eligibility to adolescents 13 to 19 years old; 2) expansion of benefits to include hospitalizations, mental health, and dental benefits; 3) changes in premium contributions; 4) more participating insurance plans, limited to managed care; 5) expansions in marketing and outreach; and 6) a combined enrollment application for SCHIP and several low-income programs including Medicaid

Beauchesne, Patrick D; Taillandier, L; Bernier, V; Carnin, C

2009-06-01

Fotemustine is a nitrosourea compound used for the treatment of malignant gliomas, especially in France. Recently, an EORTC-NCIC study has shown that a concomitant combination of radiotherapy plus temozolomide (an oral cytotoxic drug) improved survival in glioblastoma patients. We set out to test a concurrent combination of radiotherapy and fotemustine for newly malignant gliomas. A prospective single-center phase II study opened for accrual in September 2004. Patients over 18 years of age able to give informed consent and with histologically proven, newly diagnosed supratentorial malignant gliomas were eligible. All patients were treated by a standard cranial irradiation (conformal irradiation, tumor bulk plus a margin of 2.5 cm) and concomitant daily administration of 10 mg/m(2) of fotemustine (5 days per week, 6 weeks, 1 h 30 min before radiation therapy). Adjuvant chemotherapy, fotemustine, was administered at tumor progression as standard and classic regimen. Twenty-two patients were enrolled, 16 men and 6 women, median age 56 years (range 32-74), median Karnofsky performance status 70 (range 60-90). Histology included 16 glioblastomas, 3 anaplastic astrocytomas, 2 anaplastic oligodendrogliomas and 1 mixed glioma. Eight patients underwent surgery (three total resections). Fourteen patients had a stereotactic biopsy. The concurrent radiotherapy-fotemustine combination was well tolerated: toxicity was mild and three hematologic toxicities grade 3-4 were observed. Median survival from the initial diagnosis was 9.9 months, two patients are currently alive. Median survival was 11 months for surgery and 9 months for stereotactic biopsy. Concomitant radiotherapy-fotemustine combination is safe and well tolerated. Overall survival of over 10 months for the whole population compares favorably with other reports.

Bacteremia in dengue may occur with common exposure to pathogens in association with severe organ impairment or severe dengue, which may result in death. Cohort studies identifying risk factors for concurrent bacteremia among patients with dengue are rare. We conducted a retrospective case-control study of adult patients with dengue who were admitted to the Department of Infectious Diseases at Tan Tock Seng Hospital, Singapore from 2004 to 2008. For each case of dengue with concurrent bacteremia (within the first 72 hours of admission), we selected four controls without bacteremia, who were matched on year of infection and dengue confirmation method. Conditional logistic regression was performed to identify risk factors for concurrent bacteremia. Among 9,553 patients with dengue, 29 (0.3%) had bacteremia. Eighteen of these patients (62.1%) had concurrent bacteremia. The predominant bacteria were Staphylococcus aureus, one of which was a methicillin-resistant strain. Dengue shock syndrome occurred more frequently and hospital stay was longer among cases than among controls. Three cases did not survive, whereas none of the controls died. In multivariate analysis, being critically ill at hospital presentation was independently associated with 15 times the likelihood of a patient with dengue having concurrent bacteremia. Concurrent bacteremia in adult patients with dengue is uncommon but presents atypically and results in more deaths and longer hospital stay. Given the associated mortality, collection of blood cultures and empiric antibiotic therapy may be considered in patients who are critically ill. Copyright © 2015. Published by Elsevier B.V.

Among other goals, the Chronic Disease Self-Management Program (CDSMP) is designed to improve self-efficacy of the chronically ill. However, a substantial proportion of the enrollees often leave CDSMPs before completing the program curriculum. This study examines factors associated with program attrition in a CDSMP implemented in a community setting. We used data from the Our Pathways to Health program, implemented in Humboldt County, California, from 2008 to 2011. Our conceptual framework is based on Bandura's self-efficacy theory, and we used logistic regression to investigate whether baseline self-efficacy and other members' efficacy are associated with participants dropping out of the CDSMP. Twenty-three percent of the participants did not complete the program similar to previous studies. Lower baseline self-efficacy increased the odds of dropout, but other members' efficacy was not associated with differential odds of dropout. Age, educational difference between the individual and the group, weekday sessions, and social/role activity limitations are also found to be associated with program attrition. Our results suggest that participants with low starting self-efficacy may need extra help to complete the program. Further research is needed to understand how to effectively provide additional support to this group. © 2014 Society for Public Health Education.

Paavonen, Jorma

2008-06-01

In Phase II/III trials, administration of quadrivalent human papillomavirus (HPV) (types 6/11/16/18) L1 virus-like-particle vaccine was highly effective in preventing HPV6/11/16/18-related cervical intraepithelial neoplasia and non-invasive cervical cancer in women aged 16-26 years who were naïve to these HPV types at enrollment. However, the makeup and extent of catch-up vaccination programs among young women is unclear, because a proportion of this population will likely already have been exposed to one or more vaccine-HPV-types. Herein we analyze baseline data from the quadrivalent HPV vaccine clinical trial program to investigate variables which may help shape catch-up vaccine implementation policies. Female adolescents and young adults aged 16-26 years were randomized into five clinical trials. Baseline data regarding demographics, sexual history, pregnancy history, and other characteristics were collected at enrollment. At the baseline gynecological examination during enrollment, specimens were obtained for Pap testing. Swabs of external genital, lateral vaginal, and cervical sites for HPV polymerase chain reaction (PCR) testing were taken, and serum samples were obtained for HPV serology testing. Regional analyses of data were conducted. Overall, 72% of subjects enrolled worldwide were naïve by both serology and PCR to all four vaccine HPV types. Few subjects were seropositive and/or PCR positive for more than two vaccine-related HPV types. Of all subjects with HSIL at enrollment, 78% were positive to at least one vaccine-related HPV type at enrollment. Regional differences in HPV and STD prevalence were evident. Study limitations included under-representation of women with >/=4 sexual partners and possible underestimation of prior HPV exposure. Our findings demonstrate that sexually active 16-26 year-old women with America, Europe, Latin America, and Asia Pacific are generally naïve to most or all types targeted by the quadrivalent HPV6/11/16/18 vaccine

2010-04-01

A cluster survey of the age, sex and enrolment status of all school-age children 5-14 years old was undertaken in 2006 in a remote rural sub-district of the Northwest Frontier Province, Pakistan about a year after a devastating earthquake. Information was collected on the characteristics of children, their households and parents, and on reasons for non-enrolment. The health and nutritional status of a randomly selected child in each household was assessed and enrolled and non-enrolled children were compared by sex. A total of 2032 children were recorded in 925 households, 845 girls and 1187 boys, a sex ratio of 71 girls/100 boys. Half of all girls were not enrolled in school compared with a fifth of all boys. There was no common reason for non-enrolment and they differed between the sexes. The randomly selected children (n = 897) were moderately malnourished: 43% were stunted, 12% were thin and 46% were anaemic. 66% of a sub-sample of children (n = 269) had a low urinary iodine concentration, which could contribute to a low IQ and impaired hearing. There were no statistically significant differences in the nutritional status or health of non-enrolled and enrolled girls. These data contribute towards an understanding of how to improve the education and health of school-age children in a conservative, rural province of Pakistan. Copyright 2010 Elsevier Ltd.

2000-01-01

Purpose: To determine the activity and toxicity of paclitaxel and concurrent radiation for gastric cancer. Methods and Materials: Twenty-seven patients were studied. Twenty-five had proximal gastric cancers, two had distal cancers. Eight had esophageal extension, 6 had celiac adenopathy, and 7 had retroperitoneal adenopathy. Patients received paclitaxel, 50 mg/m 2 by 3-hour intravenous (IV) infusion, weekly, on days 1, 8, 15, 22, and 29. Radiation was administered concurrently to a total dose of 45.0 Gy, in 1.80 Gy fractions, for 25 treatments. Patients who were medically or surgically inoperable received a sixth week of paclitaxel with a radiation boost to 50.4 Gy. Results: Esophagitis and gastritis were the most important toxicities, Grade 3 in four patients (15%), and Grade 4 in three patients (11%). Five patients (19%) had Grade 3 nausea. The overall response rate was 56%, including three patients (11%) with a complete response. The 2-year progression-free and overall survival rates were 29% and 31%, respectively. Conclusion: Concurrent paclitaxel and radiation demonstrates substantial local-regional activity in gastric cancer. Future investigations combining paclitaxel and radiation with other local-regional and systemic treatments are warranted

A Concurrent Multiple Negotiation Protocol Based on Colored Petri Nets.

Niu, Lei; Ren, Fenghui; Zhang, Minjie; Bai, Quan

2017-11-01

Concurrent multiple negotiation (CMN) provides a mechanism for an agent to simultaneously conduct more than one negotiation. There may exist different interdependency relationships among these negotiations and these interdependency relationships can impact the outcomes of these negotiations. The outcomes of these concurrent negotiations contribute together for the agent to achieve an overall negotiation goal. Handling a CMN while considering interdependency relationships among multiple negotiations is a challenging research problem. This paper: 1) comprehensively highlights research problems of negotiations at concurrent negotiation level; 2) provides a graph-based CMN model with consideration of the interdependency relationships; and 3) proposes a colored Petri net-based negotiation protocol for conducting CMNs. With the proposed protocol, a CMN can be efficiently and concurrently processed and negotiation agreements can be efficiently achieved. Experimental results indicate the effectiveness and efficiency of the proposed protocol in terms of the negotiation success rate, the negotiation time and the negotiation outcome.

Mathematical techniques for analyzing concurrent and probabilistic systems

CERN Document Server

Rutten, J J M M; Panangaden, Prakash; Panangaden, Prakash; Breugel, Franck van

2004-01-01

The book consists of two sets of lecture notes devoted to slightly different methods of analysis of concurrent and probabilistic computational systems. The first set of lectures develops a calculus of streams (a generalization of the set of natural numbers) based on the coinduction principle coming from the theory of coalgebras. It is now well understood that the interplay between algebra (for describing structure) and coalgebra (for describing dynamics) is crucial for understanding concurrent systems. There is a striking analogy between streams and formula calculus reminiscent to those appearing in quantum calculus. These lecture notes will appeal to anyone working in concurrency theory but also to algebraists and logicians. The other set of lecture notes focuses on methods for automatically verifying probabilistic systems using techniques of model checking. The unique aspect of these lectures is the coverage of both theory and practice. The authors have been responsible for one of the most successful experi...

Study on the concurrent calculation with a multitransputer network

International Nuclear Information System (INIS)

Inomata, Shinji; Suzuki, Katsuo

1992-06-01

A relation between the calculation processing time and the overhead of multitransputer network is studied in performing several concurrent calculations. Hardware configuration we used was a ring-type linked nine transputer network on an INMOS B008 mother board which was inserted into a slot of a personal computer compatible with IBM PC/AT. Further we used the occam2 toolset of MS-DOS version to write the calculation programs in the occam2 language. On arithmetic operations, some trigonometric and transcendental functions and numerical integrations, the calculation time and overhead were measured. The results show that the relative calculation speed is proportional to the number of transputers when the ratio of calculation time to overhead is much greater than 1.0. And the overhead is consumed in inter-communicating among transputers for the parallel calculation set-up. (author)

Atsu, Benedicta K; Guure, Chris; Laar, Amos K

2017-07-27

Malnutrition (undernutrition and overnutrition) is a major public health problem in Ghana -affecting growth and development of individuals and the nation. Stunting and overweight are of particular interest, as recent national surveys show a rising trend of overnutrition and stubbornly high burden of stunting among Ghanaian children. There are currently no data on the simultaneous occurrence of overweight and stunting within individuals in Ghana. This paper presents the burden, the individual-level, and contextual determinants of overweight with concurrent stunting among Ghanaian children. This study analyzed data set of the fourth round of the Ghana Multiple Indicator Cluster Survey (MICS4). Bivariate analyses were used to describe selected characteristics of survey respondents and their children. Hierarchical modelling approach facilitated identification of significant distal, intermediate and proximal factors/determinants of concurrent stunting and overweight. Both crude and adjusted prevalence ratios via a multivariable Poison regression model with their corresponding 95% Confidence Intervals (CI) are reported. Variables with p ≤ 0.25 at the bivariate level were included in the multivariable analysis. An alpha value of 5% was used to indicate significance. Of 7550 cases (children) analyzed, the prevalence of stunting was 27.5%; underweight was 17.3%; and wasting was 7.7%. The prevalence of overweight and concurrent overweight and stunting were respectively 2.4% and 1.2%. Children who belonged to the fourth wealth quintile, were more likely to be overweight and concurrently stunted as against children belonging to the poorest quintile (aPR = 1.010; 95% CI, 1.003-1.017). Compared to religious (Christians/Muslim/Traditionalist) household heads, children whose household heads did not belong to any religion had 2 times the rates of the Overweight with concurrent stunting (PR = 2.024; 95% CI, 1.016-4.034). Children with mothers aged 20-34 and 35-49 had an

To evaluate the experience of induction chemotherapy followed by concurrent chemoradiationwith helical tomotherapy (HT) for nasopharyngeal carcinoma (NPC). Between August 2006 and December 2009, 28 patients with pathological proven nonmetastatic NPC were enrolled. All patients were staged as IIB-IVB. Patients were first treated with 2 to 3 cycles of induction chemotherapy with EP-HDFL (Epirubicin, Cisplatin, 5-FU, and Leucovorin). After induction chemotherapy, weekly based PFL was administered concurrent with HT. Radiation consisted of 70 Gy to the planning target volumes of the primary tumor plus any positive nodal disease using 2 Gy per fraction. After completion of induction chemotherapy, the response rates for primary and nodal disease were 96.4% and 80.8%, respectively. With a median follow-up after 33 months (Range, 13-53 months), there have been 2 primary and 1 nodal relapse after completion of radiotherapy. The estimated 3-year progression-free rates for local, regional, locoregional and distant metastasis survival rate were 92.4%, 95.7%, 88.4%, and 78.0%, respectively. The estimated 3-year overall survival was 83.5%. Acute grade 3, 4 toxicities for xerostomia and dermatitis were only 3.6% and 10.7%, respectively. HT for locoregionally advanced NPC is feasible and effective in regard to locoregional control with high compliance, even after neoadjuvant chemotherapy. None of out-field or marginal failure noted in the current study confirms the potential benefits of treating NPC patients by image-guided radiation modality. A long-term follow-up study is needed to confirm these preliminary findings

Background: The anti-neoplastic effect of paclitaxel has been demonstrated in various clinical studies in different malignant diseases. Clinical studies have also demonstrated a greater efficacy for simultaneous radio-chemotherapy compared with radiotherapy alone when using radiosensitizing drugs. Based on these clinical and in-vitro data we initiated several pilot studies using paclitaxel as a radiosensitizing agent and we now present our initial experience in its use in a combined modality protocol, radiation and simultaneous chemotherapy with paclitaxel. Methods: I. Concurrent paclitaxel and radiation for locally advanced non-small-cell lung cancer (NSCLC): In a phase-I-study we applicated paclitaxel (45 to 65 mg/m 2 ) as a 3-hour infusion weekly for 3 to 7 weeks simultaneously with primary radiotherapy in shrinking field technique with 5x1.8 Gy/week up to 59.4 Gy. - II. Concurrent paclitaxel and radiation for breast cancer as neoadjuvant or palliative: 50 mg/m 2 paclitaxel as a 3-hour infusion weekly for 6 weeks simultaneous with neoadjuvant or palliative radiotherapy of the breast/chest wall with 5x1.8 Gy/week up to 54.0 Gy. - III./IV. Concurrent paclitaxel/carboplatin and combined radiation (EBRT+brachytherapy) for locally advanced inoperable cancer of the cervix: 50 mg/m 2 paclitaxel as a 3-hour infusion weekly for 5 weeks, 50 mg/m 2 carboplatin at day 1 to 5 in week 1 and 5 simultaneously with external beam radiotherapy of the pelvis with 5x1.8 Gy/week up to 54.0 Gy and endocavitary LDR-brachytherapy (4x5 Gy). - V. Concurrent paclitaxel and radiation for locally advanced inoperable cancer of the bladder: 50 mg/m 2 paclitaxel as a 3-hour infusion weekly for 5 weeks simultaneous with radiotherapy of the pelvis with 5x1.8 Gy/week up to 50.4 Gy. VI. Concurrent paclitaxel and radiation in locally advanced inoperable head and neck cancer: 50 mg/m 2 paclitaxel as a 3-hour infusion weekly for 7 to 8 weeks simultaneous with radiotherapy in shrinking field technique

2005-01-01

The purpose of this study was to evaluate whether radiotherapy with carboplatin would result in longer survival than radiotherapy alone in elderly patients with unresectable stage III non-small cell lung cancer (NSCLC). Eligible patients were 71 years of age or older with unresectable stage III NSCLC. Patients were randomly assigned to the radiotherapy alone (RT) arm, irradiation with 60 Gy; or the chemoradiotherapy (CRT) arm, the same radiotherapy and additional concurrent use of carboplatin 30 mg/m 2 per fraction up to the first 20 fractions. This study was terminated early when 46 patients were registered from November 1999 to February 2001. Four patients (one in the RT arm, three in the CRT arm) were considered to have died due to treatment-related causes. The Japan Clinical Oncology Group (JCOG) Radiotherapy Committee assessed these treatment-related deaths (TRDs) and the compliance with radiotherapy in this trial. They found that 60% of the cases corresponded to protocol deviation and 7% were protocol violation in dose constraint to the normal lung, two of whom died due to radiation pneumonitis. As to the effectiveness for the 46 patients enrolled, the median survival time was 428 days [95% confidence interval (CI)=212-680 days]in the RT arm versus 554 days (95% CI=331 to not estimable) in the CRT arm. Due to the early termination of this study, the effectiveness of concurrent use of carboplatin remains unclear. We're-planned and started a study with an active quality control program which was developed by the JCOG Radiotherapy Committee. (author)

African American women are disproportionately affected by HIV/AIDS. Concurrent sexual partnerships may contribute to racial disparities in HIV infection. Little is known about attitudes and practices related to concurrency among African American women, or the social, structural and behavioural factors influencing concurrency. We recruited 19 heterosexual African American women engaging in concurrent sexual partnerships from a public clinic in Philadelphia in 2009. We conducted interviews exploring social norms, attitudes and practices about concurrency, and the structural, social and behavioural factors influencing concurrent sexual partnerships, guided by grounded theory. Seventeen women reported one main and one or more non-main partners; two reported no main partners. Many women used condoms more frequently with non-main than main partners, noting they trust main partners more than non-main partners. Social factors included social normalisation of concurrency, inability to negotiate partners' concurrent partnerships, being unmarried, and not trusting partners. Lack of trust was the most commonly cited reason that women engaged in concurrent partnerships. Structural factors included economic dependence on partners, partners' dependence on women for economic support and incarceration that interrupted partnerships. Behavioural factors included alcohol and cocaine use. Social, structural and behavioural factors strongly influenced these African American women's concurrent sexual partnerships. Many HIV interventions disseminated by the CDC focus largely on behavioural factors and may fail to address the social and structural factors influencing African American women's sexual networks. Novel HIV prevention interventions that address the social determinants of African American women's HIV risks are urgently needed.

Separative power of an optimised concurrent gas centrifuge

The problem of separation of isotopes in a concurrent gas centrifuge is solved analytically for an arbitrary binary mixture of isotopes. The separative power of the optimised concurrent gas centrifuges for the uranium isotopes equals to δU = 12.7 (V/700 m/s)2(300 K/T)(L/1 m) kg·SWU/yr, where L and V are the length and linear velocity of the rotor of the gas centrifuge and T is the temperature. This equation agrees well with the empirically determined separative power of optimised counter-current gas centrifuges.

OBJECTIVE Concurrent surgeries, also known as "running two rooms" or simultaneous/overlapping operations, have recently come under intense scrutiny. The goal of this study was to evaluate the operative time and outcomes of concurrent versus nonconcurrent vascular neurosurgical procedures. METHODS The authors retrospectively reviewed 1219 procedures performed by 1 vascular neurosurgeon from 2012 to 2015 at the University of California, San Francisco. Data were collected on patient age, sex, severity of illness, risk of mortality, American Society of Anesthesiologists (ASA) status, procedure type, admission type, insurance, transfer source, procedure time, presence of resident or fellow in operating room (OR), number of co-surgeons, estimated blood loss (EBL), concurrent vs nonconcurrent case, severe sepsis, acute respiratory failure, postoperative stroke causing neurological deficit, unplanned return to OR, 30-day mortality, and 30-day unplanned readmission. For aneurysm clipping cases, data were also obtained on intraoperative aneurysm rupture and postoperative residual aneurysm. Chi-square and t-tests were performed to compare concurrent versus nonconcurrent cases, and then mixed-effects models were created to adjust for different procedure types, patient demographics, and clinical indicators between the 2 groups. RESULTS There was a significant difference in procedure type for concurrent (n = 828) versus nonconcurrent (n = 391) cases. Concurrent cases were more likely to be routine/elective admissions (53% vs 35%, p returns to the OR (3.3% vs 6.9%; all p return to the OR and 30-day mortality were significantly lower in concurrent cases (odds ratio 0.55, 95% confidence interval 0.31-0.98, p = 0.0431, and odds ratio 0.81, p fashion. After adjusting for patient demographics, procedure type, and clinical indicators, concurrent cases had longer procedure times, but equivalent patient outcomes, as compared with nonconcurrent vascular neurosurgical procedures.

Machine Protection System for Concurrent Operation of RHIC and BLIP

Wilinski, Michelle; Glenn, Joseph; Mausner, Leonard; Unger, Kerry

2005-01-01

The Brookhaven 200 MeV linac is a multipurpose machine used to inject low intensity polarized protons ultimately ending up in RHIC as well as to inject high intensity protons to BLIP, a medical isotope production facility. If high intensity protons were injected to RHIC by mistake, administrative radiation limits could be exceeded or sensitive electronics could be damaged. In the past, the changeover from polarized proton to high intensity proton operation has been a lengthy process, thereby never allowing the two programs to run simultaneously. To remedy this situation and allow for concurrent operation of RHIC and BLIP, an active interlock system has been designed to monitor current levels in the AGS using two current transformers with fail safe circuitry and associated electronics to inhibit beam to RHIC if high intensity is detected.

Purpose: The primary objective of this study was to determine the maximum-tolerated dose (MTD) of S-1, an oral fluoropyrimidine derivative, with concurrent radiotherapy in patients with unresectable locally advanced pancreatic cancer. Methods and Materials: Patients with histopathologically proven, unresectable, locally advanced pancreatic cancer were eligible. Radiotherapy was delivered in 1.8 Gy daily fractions to a total dose of 50.4 Gy over 5.5 weeks. S-1 was administered orally twice a day from Day 1 to 14 and 22 to 35 at escalating doses from 60 to 80 mg/m 2 /day. Results: Sixteen patients were enrolled in this study. Three patients received S-1 at 60 mg/m 2 /day, 3 at 70 mg/m 2 /day, and 10 at 80 mg/m 2 /day. Though 1 patient at the final dose level (80 mg/m 2 /day) experienced a dose limiting toxicity (biliary infection with Grade 3 neutropenia), the MTD was not reached in this study. The most common toxicities were anorexia and leukocytopenia, with Grade 3 toxicity occurring in 31% and 6.3% of the patients, respectively. Conclusions: The recommended dose of S-1 with concurrent radiotherapy was determined to be 80 mg/m 2 /day from Day 1 to 14 and 22 to 35 in patients with locally advanced pancreatic cancer. Oral S-1 and radiotherapy is well tolerated and feasible and should be further investigated

Purpose: To define the safety, efficacy, and pharmacogenetic and pharmacodynamic effects of sorafenib with gemcitabine-based chemoradiotherapy (CRT) in locally advanced pancreatic cancer. Methods and Materials: Patients received gemcitabine 1000 mg/m{sup 2} intravenously weekly × 3 every 4 weeks per cycle for 1 cycle before CRT and continued for up to 4 cycles after CRT. Weekly gemcitabine 600 mg/m{sup 2} intravenously was given during concurrent intensity modulated radiation therapy of 50 Gy to gross tumor volume in 25 fractions. Sorafenib was dosed orally 400 mg twice daily until progression, except during CRT when it was escalated from 200 mg to 400 mg daily, and 400 mg twice daily. The maximum tolerated dose cohort was expanded to 15 patients. Correlative studies included dynamic contrast-enhanced MRI and angiogenesis genes polymorphisms (VEGF-A and VEGF-R2 single nucleotide polymorphisms). Results: Twenty-seven patients were enrolled. No dose-limiting toxicity occurred during induction gemcitabine/sorafenib followed by concurrent CRT. The most common grade 3/4 toxicities were fatigue, hematologic, and gastrointestinal. The maximum tolerated dose was sorafenib 400 mg twice daily. The median progression-free survival and overall survival for 25 evaluable patients were 10.6 and 12.6 months, respectively. The median overall survival for patients with VEGF-A -2578 AA, -1498 CC, and -1154 AA versus alternate genotypes was 21.6 versus 14.7 months. Dynamic contrast-enhanced MRI demonstrated higher baseline K{sup trans} in responding patients. Conclusions: Concurrent sorafenib with CRT had modest clinical activity with increased gastrointestinal toxicity in localized unresectable pancreatic cancer. Select VEGF-A/VEGF-R2 genotypes were associated with favorable survival.

1999-01-01

This is to evaluate the acute complication, resection rate, and tumor down-staging after pre-operative concurrent chemoradiotherapy for stage IIIA (N2) non-small cell lung cancer. Fifteen patients with non-small cell lung cancer were enrolled in this study from May 1997 to June 1998 in Samsung Medical Center. The median age of the patients was 61 (range, 45-67) years and male to female ratio was 12:3. Pathologic types were squamous cell carcinoma (11) and adenocarcinoma (4). Pre-operative clinical tumor stages were cT1 in 2 patients, cT2 in 12, and cT3 in 1 and all were N2. Ten patients were proved to be N2 with mediastinoscopic biopsy and five had clinically evident mediastinal lymph node metastases on the chest CT scans. Pre-operative radiation therapy field included the primary tumor, the ipsilateral hilum, and the mediastinum. Total radiation dose was 45 Gy over 5 weeks with daily dose of 1.8 Gy. Pre-operative concurrent chemotherapy consisted of two cycles of intraventous cis-Platin (100 mg/m 2 ) on day 1 and oral Etoposide (50 mg/m 2 /day) on days 1 through 14 with 4 weeks' interval. Surgery was followed after the pre-operative re-evaluation including chest CT scan in 3 weeks of the completion of the concurrent chemoradiotherapy if there was no evidence of disease progression. Full dose radiation therapy was administered to all the 15 patients. Planned two cycles of chemotherapy was completed in 11 patients and one cycle was given to four. One treatment related death of acute respiratory distress syndrome occurred in 15 days of surgery. Hospital admission was required in three patients including one with radiation pneumonitis and two with neutropenic fever. Hematologic complications and other acute complications including esophagitis were tolerable. Resection rate was 92.3% (12/13) in 13 patients excluding two patients who refused surgery. Pleural seeding was found in one patient after thoracotomy and tumor resection was not feasible. Post-operative tumor

Sangar, Vijay K.; McBain, Catherine A.; Lyons, Jeanette; Ramani, Vijay; Logue, John; Wylie, James; Clarke, Noel W.; Cowan, Richard A.

2005-01-01

Purpose: A prospective phase I trial was conducted to determine the maximal tolerated dose of gemcitabine given once weekly during hypofractionated conformal radiotherapy to patients with locally advanced transitional cell carcinoma of the bladder. Eight male patients, median age 69 years, with Stage T2 (n = 4) or T3 (n = 4) N0M0, were enrolled in cohorts of 3. Treatment comprised conformal radiotherapy (52.5 Gy in 20 fractions) within 4 weeks, with concurrent gemcitabine once weekly for four cycles. The weekly gemcitabine dose was escalated from 100 mg/m 2 in increments of 50 mg/m 2 per cohort. Dose-limiting toxicity was defined as any acute Radiation Therapy Oncology Group (RTOG) toxicity Grade 3 or greater arising in >1 of 3 patients in each cohort. Tumor response was assessed cystoscopically and radiologically at 3 months. Results: All 8 patients completed radiotherapy, and 6 of 8 completed chemoradiotherapy. No acute toxicity greater than RTOG Grade 1 was seen with gemcitabine at 100 mg/m 2 . Dose-limiting toxicity was observed at 150 mg/m 2 with Grade 3 toxicity seen in 2 of 2 patients (one bladder, one bowel). An additional 3 patients received 100 mg/m 2 with minimal toxicity. No hematologic toxicity was encountered. A complete response was seen in 7 (87.5%) of 8 patients, all of whom were disease free at a median follow-up of 19.5 months (range, 14-23 months). No late toxicity (greater than RTOG Grade 0) has been observed. Conclusion: The maximal tolerated dose for gemcitabine given once weekly with concurrent hypofractionated conformal bladder radiotherapy was 150 mg/m 2 , with a maximal recommended dose of 100 mg/m 2 . This dose regimen has now entered Phase II clinical trials

Ream, Geoffrey L; Elliott, Luther C; Dunlap, Eloise

2011-10-01

"Behavioral addictions" share biological mechanisms with substance dependence, and "drug interactions" have been observed between certain substances and self-reinforcing behaviors. This study examines correlates of patterns of and motivations for playing video games while using or feeling the effects of a substance (concurrent use). Data were drawn from a nationally-representative survey of adult Americans who "regularly" or "occasionally" played video games and had played for at least one hour in the past seven days (n = 3,380). Only recent concurrent users' data were included in analyses (n = 1,196). Independent variables included demographics, substance use frequency and problems, game genre of concurrent use (identified by looking titles up in an industry database), and general game playing variables including problem video game play (PVP), consumer involvement, enjoyment, duration, and frequency of play. Exploratory factor analysis identified the following dimensions underlying patterns of and motivations for concurrent use: pass time or regulate negative emotion, enhance an already enjoyable or positive experience, and use of video games and substances to remediate each other's undesirable effects. Multivariate regression analyses indicated PVP and hours/day of video game play were associated with most patterns/motivations, as were caffeine, tobacco, alcohol, marijuana, and painkiller use problems. This suggests that concurrent use with some regular situational pattern or effect-seeking motivation is part of the addictive process underlying both PVP and substance dependence. Various demographic, game playing, game genre of concurrent use, and substance use variables were associated with specific motivations/patterns, indicating that all are important in understanding concurrent use.

Science, Technology, Engineering, and Mathematics (STEM) fields are critical for meeting ever-increasing demands in the U.S. for STEM and related skills, and for ensuring the global competitiveness of the United States in technological advancement and scientific innovation. Nonetheless, few U.S. students consider a STEM degree after high school and fewer STEM students end up graduating with a STEM degree. In 2012, the United States ranked 35th in math and 27th in science out of 64 participating countries in the Program for International Student Assessment (PISA), sponsored by the Organization for Economic Cooperation and Development (OECD). Considering the significant role physics and engineering play in technological advancement, this work investigates the attitudes of students and recent enrollment trends in these important subject areas.

Digital communications networks have the intrinsic capability of time synchronization which makes it possible for networks to supply time signals to some applications and services. A practical estimation method for the time concurrency on terrestrial networks is presented. By using this method, time concurrency capability of the Nippon Telegraph and Telephone Corporation (NTT) digital communications network is estimated to be better than 300 ns rms at an advanced level, and 20 ns rms at final level.
