    Tanner-Smith, Emily E; Wilson, Sandra Jo

    2013-10-01

    This study reports findings from a systematic review and meta-analysis of literature examining the effects of school dropout prevention and intervention programs on students' school absenteeism outcomes. The meta-analysis synthesized 74 effect sizes measuring posttest differences in school absenteeism outcomes for youth enrolled in dropout prevention programs relative to a comparison group. Although results from randomized controlled trials indicated significant beneficial program effects, findings from quasi-experimental studies indicated no significant beneficial or detrimental effects. Examination of study characteristics suggested that dropout programs may have beneficial effects on school absenteeism among primarily male samples, and younger samples. Although no single type of intervention program was consistently more effective than others, vocational oriented and supplemental academic training programs showed some promise. However, the inconsistency in results and the possibility of small study bias mean the quality of evidence in this literature is low; at this time there is not enough evidence to conclude that dropout prevention programs have a universal impact on youth's school absenteeism outcomes.

    Many advocacy organizations devote time and resources to increasing community awareness and educating the public in an effort to gain support for their issue. One such effort, the Dropout Prevention Campaign by America's Promise Alliance, aimed to increase the visibility of the high school dropout problem and mobilize the community to take action. The objective of this paper is to evaluate the framing of the Dropout Prevention Campaign in television news media. To evaluate this campaign, television news coverage about high school dropout in 12 U.S. communities (N = 982) was examined. A content analysis of news transcripts was conducted and coded to determine the definition of the problem, the reasons for dropout and the possible solutions. Findings indicated that the high school dropout problem was most often framed (30 % of news segments) in terms of the economic and societal implications for the community. Individual student factors as well as broader societal influences were frequently discussed as possible reasons for dropout. The most commonly mentioned solutions were school-based interventions. News segments that mentioned America's Promise Alliance were more likely to frame the issue as a crisis and to use statistics to illustrate that point. Solutions that were more likely to appear in America's Promise segments promoted community and cross-sector involvement, consistent with the messages promoted by the Dropout Prevention Campaign. The findings suggest that a media content analysis can be an effective framework for analyzing a prevention campaign.

  12. Treatment planning: A key milestone to prevent treatment dropout in adolescents with borderline personality disorder.

    Science.gov (United States)

    Desrosiers, Lyne; Saint-Jean, Micheline; Breton, Jean-Jacques

    2015-06-01

    The aim of this study was to gain a broader appreciation of processes involved in treatment dropout in adolescents with borderline personality disorder (BPD). A constructivist grounded theory was chosen using a multiple-case research design with three embedded levels of analysis (adolescent, parent, and care setting). Theoretical sampling and the different stages of analysis specific to grounded theory were performed according to the iterative process of constant comparative analysis. Twelve cases were examined (nine dropouts among adolescents with BPD and for the purpose of falsification, one dropout of suicidal adolescent without BPD and two completed treatments among adolescents with BPD). To document the cases, three groups of informants were recruited (adolescents, parents, and therapists involved in the treatment) and 34 interviews were conducted. Psychological characteristics, perception of mental illness and mental health care, and help-seeking context were the specific treatment dropout vulnerabilities identified in adolescents with BPD and in their parents. However, their disengagement became an issue only when care-setting response--including mitigation of accessibility problems, adaptation of services to needs of adolescents with BPD, preparation for treatment, and concern for clinicians' disposition to treat--was ill-suited to these treatment dropout vulnerabilities. Treatment planning proves to be a key milestone to properly engage adolescents with BPD and their parent. Systematic assessment of treatment dropout vulnerabilities before the intervention plan is laid out could foster better-suited responses of the care setting thus decreasing the incidence of treatment discontinuation in adolescents with BPD. Treatment dropout vulnerabilities specific to adolescents with BPD and their parents can be detected before the beginning of treatment. Premature treatment termination may be prevented if the care setting considers these vulnerabilities at treatment

    Full Text Available School dropout has significant consequences for both individuals and societies. Only 21% of adults in Mexico achieve the equivalent of a high school education. We examined the relationship between school dropout and self-reported psychiatric symptoms in a middle school in a suburb of Mexico City. We used binomial logistic regression to examine the odd ratio of school dropout associated with student’s self-reported psychopathology. Two-hundred thirty seven students participated in the study. Psychosis (Odds Ratio (OR=8.0 (95% Confidence Interval (CI: 1.7-37.2, depression (OR=4.7 (95% CI: 2.2-9.7, tic disorders (OR=3.7 (95%CI: 1.4-9.5, ADHD (OR=3.2 (95%CI:1.5-6.4, and social phobia (OR=2.6 (95%CI: 1.2-5.8 were associated with increased risk of school dropout after controlling for age and gender as covariates. Our study suggested that students’ self-reported psychopathology is associated with increased school dropout in Mexico.

    The drop-out rate among patients receiving preventive treatment for migraine is higher than 30%. This situation is not very widely known and the risk factors that lead patients to drop out from treatment have yet to be identified. To evaluate some of the factors that can predispose patients to drop out of preventive treatment. We conducted a prospective study of patients suffering from migraine who required preventive treatment for the first time with one of what are considered the top three first-choice drugs, i.e. a beta-blocker (nadolol), a neuromodulator (topiramate) or a calcium antagonist (flunarizine). Two groups were established according to whether patients dropped out of treatment or not. Different demographic and clinical variables were analysed and compared in the two groups. Of 800 patients with migraine who required preventive treatment for the first time, the drop-out rate was 19.7%. In the drop-out group, the variables 'age', 'number of seizures', 'number of seizures prior to preventive treatment' and 'side effects' showed significant differences with those from the group of patients who did not drop out of preventive treatment. The drug used as preventive treatment, the side effects, a younger age and a lower number of seizures before starting the preventive treatment favoured higher drop-out rates. Whether the migraine was episodic or chronic, the presence of medication abuse and the drugs used to treat the seizures were not related with dropping out of preventive treatment. © 2011 Revista de Neurología

    Patients with antisocial personality disorder in outpatient treatment for substance use disorders are at high risk of drop-out. Using a randomized design, this study tested the impact of adding a brief psycho-educational program, the Impulsive Lifestyle Counseling program, to outpatient substance abuse treatment in order to prevent treatment dropout. Patients (N=175) were recruited from 13 municipal treatment centers in Denmark, and assigned to treatment as usual or to the experimental condition. In all, 172 patients could be included in the analyses. In the intent-to-treat analysis, the risk of treatment dropout was reduced among patients randomized to the experimental program (hazard ratio=0.63, p=.031), after controlling for age, gender, and substitution treatment status. The study supported the efficacy of the Impulsive Lifestyle Counseling program as a method for preventing treatment dropout for patients with comorbid antisocial personality disorder in substance abuse treatment.

    Attrition is an important but understudied issue that plays a vital role in the successful treatment of obesity. To date, most studies focusing on attrition rates and/or its predictors have been based on pretreatment data routinely collected for other purposes. Our study specifically aims at identifying the predictors of drop-out focusing on empirically or theoretically-based factors. We conducted a retrospective observational study in an academic outpatient clinical nutrition service in Pavia, Italy. We examined a total of 98 adult obese patients (36 males, 62 females) who underwent a 6-month dietary behavioral weight-loss treatment at our Center. Pre-treatment and treatment-related variables were collected or calculated from clinical charts in order to discriminate those subjects who completed treatment from those who abandoned it before its completion. Multivariable regression analysis was used to identify the independent predictors of drop-out. The drop-out rates were 21% at 1 month and 57% at 6 months. Compared with completers, noncompleters were significantly younger in terms of age at first dieting attempt (24.0 ± 10.7 vs. 31.3 ± 11.2 years, P = 0.005), had lower diastolic blood pressure (87.8 ± 9.7 vs. 92.7 ± 11.4 mmHg, P = 0.022), had a lower baseline body fat percentage (38.5 ± 6.4 vs. 41.2 ± 4.4% weight, P = 0.015), and had a lower percentage of early weight loss (-1.8 ± 1.8% vs. -3.1 ± 2.1%, P = 0.035). Moreover, noncompleters significantly differed from completers with regard to type of referral (34.1% vs. 53.3% sent by a physician, P = 0.036) and SCL-90 anger-hostility subscale (0.83 ± 0.72 vs. 0.53 ± 0.51, P = 0.022). A multivariable logistic regression analysis including pre-treatment variables showed that body fat percentage (P = 0.030) and SCL-90 anger-hostility subscale (P = 0.021) were independently associated with attrition.

  5. Dropout--Mertonian or reproduction scheme?

    Science.gov (United States)

    Horowitz, T R

    1992-01-01

    This article reports on dropouts in four schools in Israel. Two main research questions were addressed: (1) Is it possible to identify a potential dropout through examination of his/her attitudes and competence before the actual act of leaving school? (2) Is there a difference between dropouts and persistent students in different educational settings (academic, vocational, agricultural, and comprehensive high schools)? Significant differences were found in the attitudes of persistent students and dropouts even before the act of dropping out occurred. In the vocational, comprehensive, and agricultural schools, the dropouts scored more positively on the self-estrangement, meaninglessness, and misfeasance scales. In the academic school, the dropouts scored positively on the anxiety scale. Results were interpreted in light of the Mertonian scheme of ends and means as well as the reproduction scheme. The Mertonian scheme was deemed more applicable.

  6. The Societal Benefits and Costs of School Dropout Recovery

    Directory of Open Access Journals (Sweden)

    James S. Catterall

    2011-01-01

    Full Text Available This article reports an analysis of the societal benefits and costs of recovering school dropouts. Successful recovery is defined by subsequent graduation from high school. The analysis is based on established estimates of the societal costs of dropping out including reduced government tax collections and higher social costs of welfare, healthcare, and crime. These potential costs are cast as benefits when a dropout is recovered. A large dropout recovery program provides the setting for the analysis. Rigorous attention is given to accurate estimation of the number of students who would not have graduated without the program in the year assessed and to the induced public costs of their continued education. Estimated benefits are weighed against the total annual public costs of the program, which operates in 65 school centers and commands an annual budget of about $70 million. The estimated benefit-cost ratio for this program is 3 to 1, a figure comparable to benefit-cost ratio estimates reported in studies of dropout prevention. The sensitivity of this conclusion to specific assumptions within the analysis is discussed.

    Researchers conducted an evaluation of participants' perceptions of a dropout prevention program - the NBA High School program - involving a National Basketball Association (NBA) team, a high school located in downtown [City], and the College of Education (COE) at the local State University (SU). The program targeted "at-risk" high school students while utilizing student-teachers as tutors and mentors. Researchers utilized mixed methods to assess student, student-teacher, and high school teacher participants' experiences with and opinions of the program. Researchers found (1) students enjoyed the program, especially given the involvement of the student-teachers; (2) students believed the program helped improve their grades; (3) student-teachers enjoyed working with their students, although student-teachers found some of the expectations surrounding their positions and roles as tutors/mentors within the high school to be unclear and frustrating; (4) high school teachers felt significantly better about the program than the student-teachers; and (5) overall, all sets of respondents categorically supported the program and its benefits. Findings indicated that the involvement of mentors or role models matters to students, and clear and organized logistics, planning, and communication are integral for program success.

    The purpose of this research was to describe our group counseling methods for medical students with drop-out experiences. Group counseling was offered to 11 medical students with drop-out experiences in their previous second semester. All subjects provided written informed consent before participating and completed a 2-day group counseling program using the Gestalt approach. The self-assertiveness training group counseling program consisted of 6 sessions, each of which lasted 90 minutes. Experience reports by participants after the program and data from semi-structured qualitative interviews were qualitatively analyzed. Program participants reported that they were moderately satisfied with the program regarding its usefulness and helpfulness on self-awareness, understanding, and reminding them of attempts to change behavior. Most students showed heightened levels of sincerity perceptions and positive attitudes in every session. The results demonstrated significant changes in experience in self-esteem, self-recognition, and interpersonal relationships. A group counseling program using the Gestalt approach could help medical students with drop-out experiences to adjust with 1 year their juniors, enhance their self-esteem, contribute to their psychological well-being, and prevent student re-failure through effective stress management and improved interpersonal relationships.

    2015-01-01

    The role of therapeutic processes in predicting premature termination of psychotherapy has been a particular focus of recent research. The purpose of this study was to contrast outpatients who completed therapy and those who dropped out with respect to their self-reported in-session experiences of self-esteem, mastery, clarification and the therapeutic alliance. The 296 patients with mixed disorders were treated with an integrative form of cognitive-behavioural therapy without pre-determined time limit (M = 20.2 sessions). Multilevel analyses indicated that patients who did not completetreatment reported, on average, lower levels of self-esteem, mastery and clarification and lower ratings of their therapeutic alliance in treatment in contrast to patients who completed therapy. Patient-reported change in self-esteem experiences over the course of treatment turned out to be the strongest predictor of dropout from psychotherapy or successful completion. When dropout occurred before the average treatment length was reached, patients reported fewer clarifying experiences as early as the first session and their ratings of the therapeutic alliance were characterized by an absence of positive development. Both of these aspects seem to be involved in patients' decisions to leave treatment early. The findings underscore the importance of the therapeutic process in understanding the mechanisms behind treatment dropout. Analyses data from 296 patients at a private outpatient clinic in a routine practice setting (CBT). Completer/dropout definition: presence or absence of measurement battery at post-assessment. Focuses on change in therapy processes by investigating post-session reports. Finds that positive changes in self-esteem experiences is the most robust predictor of dropout, followed by ratings of clarification experiences and the global alliance. In line with recent dropout research, these process indicators might help to detect therapeutic situations that are

    In this longitudinal study, we investigated the role of word reading and mathematical difficulties measured in 9th grade as factors for receiving educational support for learning in upper secondary education in Grades 10 to 12 (from ages 16 to 19) and furthermore as predictors of dropout from upper secondary education within 5 years after compulsory education. In addition, we studied the role of school achievement in Grades 9 and 11 in this prediction. The participants of this study were members of one age group of 16-year-old ninth graders (N = 595, females 302, males 293) in a midsized Finnish city, who were followed for 5 years after completing compulsory education. The path model results, where the effects of gender, educational track, and SES were controlled, showed, first, that students with academic learning difficulties received educational support for learning particularly in the 11th grade. Second, academic learning difficulties directly affected school achievement in the 9th grade, but no longer in the 11th grade. Third, mathematical difficulties directly predicted dropout from upper secondary education, and difficulties in both word reading and mathematics had an indirect effect through school achievement in Grades 9 and 11 on dropout.

    BACKGROUND. Drop-out from psychotherapy is common and represents a considerable problem in clinical practice and research. Aim. To explore pre-treatment predictors of early and late drop-out from psychodynamic group therapy in a public outpatient unit for non-psychotic disorders in Denmark. Methods. Naturalistic design including 329 patients, the majority with mood, neurotic and personality disorders referred to 39-session group therapy. Predictors were socio-demographic and clinical variables, self-reported symptoms (Symptom Check List-90-Revised) and personality style (Millon Clinical Multiaxial Inventory-II). Drop-out was classified into early and late premature termination excluding patients who dropped out for external reasons. Results. Drop-out comprised 20.6% (68 patients) of the sample. Logistic regression revealed social functioning, vocational training, alcohol problems and antisocial behavior to be related to drop-out. However, early drop-outs had prominent agoraphobic symptoms, lower interpersonal sensitivity and compulsive personality features, and late drop-outs cognitive and somatic anxiety symptoms and antisocial personality features. Clinical and psychological variables accounted for the major part of variance in predictions of drop-out, which ranged from 15.6% to 19.5% (Nagelkerke Pseudo R-Square). Conclusion. Social functioning was consistently associated with drop-out, but personality characteristics and anxiety symptoms differentiated between early and late drop-out. Failure to discriminate between stages of premature termination may explain some of the inconsistencies in the drop-out literature. Clinical implications. Before selection of patients to time-limited psychodynamic groups, self-reported symptoms should be thoroughly considered. Patients with agoraphobic symptoms should be offered alternative treatment. Awareness of and motivation to work with interpersonal issues may be essential for compliance with group therapy.

  3. Predictors of dropout among men who batter: a review of studies with implications for research and practice.

    Identifying the characteristics of men who drop out of batterers' programs is crucial for prevention, intervention, and research. This article reviews studies of program attrition to establish a description of men who fail to complete group-based batterers' interventions. Studies indicate that men who drop out are more likely to be unemployed, be unmarried and/or childless, have lower incomes, and less education than men who remain. Dropouts are also more likely to have a criminal history, to report substance abuse or related problems, and to present with particular relationship concerns or orientations. The relationship between court referral and dropout was inconsistent across studies and may vary according to socioeconomic status. Psychopathology is consistently related to dropout, but may be associated with other factors (e.g., comorbidity or referral source). Age, race, childhood exposure to violence, and battering history are all inconsistently associated with dropping out. The implications of these findings for research and program development are discussed.

    Although the concept of school engagement figures prominently in most school dropout theories, there has been little empirical research conducted on its nature and course and, more importantly, the association with dropout. Information on the natural development of school engagement would greatly benefit those interested in preventing student alienation during adolescence. Using a longitudinal sample of 11,827 French-Canadian high school students, we tested behavioral, affective, cognitive indices of engagement both separately and as a global construct. We then assessed their contribution as prospective predictors of school dropout using factor analysis and structural equation modeling. Global engagement reliably predicted school dropout. Among its three specific dimensions, only behavioral engagement made a significant contribution in the prediction equation. Our findings confirm the robustness of the overall multidimensional construct of school engagement, which reflects both cognitive and psychosocial characteristics, and underscore the importance attributed to basic participation and compliance issues in reliably estimating risk of not completing basic schooling during adolescence.

    For the last ten years drop out of vocational education has increased strongly in Denmark. Only half of the students, who take up a vocational programme on upper secondary level, complete it. Like in other European countries the low completion rates has caused considerable alarm on the political...... level (Lamb and Markussen 2011). Continuing high dropout rates will make it very hard for the government to reach its target for educational completion, and the government has launched a series of measures to increase retention including the obligation for all colleges to make plans for retention...

  8. Finishing high school: alternative pathways and dropout recovery.

    Tyler, John H; Lofstrom, Magnus

    2009-01-01

    John Tyler and Magnus Lofstrom take a close look at the problems posed when students do not complete high school. The authors begin by discussing the ongoing, sometimes heated, debate over how prevalent the dropout problem is. They note that one important reason for discrepancies in reported dropout rates is whether holders of the General Educational Development (GED) credential are counted as high school graduates. The authors also consider the availability of appropriate student data. The overall national dropout rate appears to be between 22 and 25 percent, but the rate is higher among black and Hispanic students, and it has not changed much in recent decades. Tyler and Lofstrom conclude that schools are apparently doing about as well now as they were forty years ago in terms of graduating students. But the increasingly competitive pressures associated with a global economy make education ever more important in determining personal and national well-being. A student's decision to drop out of school, say the authors, is affected by a number of complex factors and is often the culmination of a long process of disengagement from school. That decision, not surprisingly, carries great cost to both the student and society. Individual costs include lower earnings, higher likelihood of unemployment, and greater likelihood of health problems. Because minority and low-income students are significantly more likely than well-to-do white students to drop out of school, the individual costs fall unevenly across groups. Societal costs include loss of tax revenue, higher spending on public assistance, and higher crime rates. Tyler and Lofstrom go on to survey research on programs designed to reduce the chances of students' dropping out. Although the research base on this question is not strong, they say, close mentoring and monitoring of students appear to be critical components of successful programs. Other dropout-prevention approaches associated with success are family

    Backgrounds: The high rates of school dropout worldwide and their relevance highlight the need for a close study of its causes and consequences. Literature has suggested that school dropout might be explained by multiple causes at different levels (individual, family, school, and neighborhood). The aim of the current study is to examine the relation between individual (defiant attitude, irresponsibility, alcohol abuse, and illegal drugs use), family (educational figure absent and parental monitoring), school factors (truancy and school conflict) and school dropout. Method: Judicial files of all juvenile offenders (218 males and 46 females) with a judicial penal measure in Asturias (Spain) in the year 2012 were examined. Multivariate logistic regression analyses were performed to estimate the relationships between school dropout and individual, family and school variables. Results: As for the individual characteristics, results showed that school dropouts were more irresponsible than non-dropouts. Also they had higher rates of illegal drug use and alcohol abuse. Moreover, lack of parental monitoring emerged as a key predictive factor of school dropout, beyond the type of family structure in terms of the presence of both or only one educational figure. Finally, school factors did not show a significant relationship to school dropout. Conclusions: These findings indicate that school dropout is a multidimensional process. School and family policies that emphasize the role of parental monitoring and prevent alcohol and substance abuse are recommended. PMID:28082934

    School dropout in adolescents can have negative consequences, not only for the individual and the family, but also for the society. To identify the characteristics associated with the occurrence of this event might contribute to the planning of a prevention strategy. To evaluate the relationship between the individual and home characteristics and school dropout in adolescents from 12 to 17 years old in Colombia. A cross sectional study was conducted from information taken from the results obtained in the 2015 National Mental Health Survey. A study was made of the relationship between the individual and home characteristics and school dropout in adolescents from 12 to 17 years old RESULTS: A higher percentage of school dropouts was found in the older adolescents, females, and those who have children. Among the home characteristics, it was observed that those homes with more than two people, located in rural area, or that are classified as poor, have an increased percentage of school dropout adolescents. Strategies for which the main goal is to prevent school dropout should consider populations with higher prevalence of out-of-school adolescents (female, homes in rural area, or household poverty). Preventive actions of adolescent pregnancy might contribute to reduce the school dropout rate. Copyright © 2016 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España.

    Nowadays, the role of a tutor is more important than ever to prevent students dropout and improve their academic performance. This work proposes a data-driven system to extract relevant information hidden in the student academic data and, thus, help tutors to offer their pupils a more proactive personal guidance. In particular, our system, based on machine learning techniques, makes predictions of dropout intention and courses grades of students, as well as personalized course recommendations. Moreover, we present different visualizations which help in the interpretation of the results. In the experimental validation, we show that the system obtains promising results with data from the degree studies in Law, Computer Science and Mathematics of the Universitat de Barcelona.

The main purpose of these actions was to promote student participation and student identification with their school. Studies prepared by the Ministry of Education and the Comptroller of the Republic were revised to assess the impact of these actions. The result of these actions does not show an actual decrease in the number of students who leave high school. Therefore, a more holistic view is necessary to ensure the students’ stay. This review suggests using use the concept of student engagement and applying a three tier system-wide dropout preventive actions: universal, targeted and intensive.

This work proposes a data-driven system to extract relevant information hidden in the student academic data and, thus, help tutors to offer their pupils a more proactive personal guidance. In particular, our system, based on machine learning techniques, makes predictions of dropout intention and courses grades of students, as well as personalized course recommendations. Moreover, we present different visualizations which help in the interpretation of the results. In the experimental validation, we show that the system obtains promising results with data from the degree studies in Law, Computer Science and Mathematics of the Universitat de Barcelona.

    Technological advances such as massively parallel sequencing enable increasing amounts of genetic information to be obtained from increasingly challenging samples. Certainly on low template, degraded and multi-contributor samples, drop-outs will increase in number for many profiles simply by analyzing more loci, making it difficult to probabilistically assess how many drop-outs have occurred and at which loci they might have occurred. Previously we developed a Random Man Not Excluded (RMNE) method that can take into account allelic drop-out while avoiding detailed estimations of the probability that drop-outs have occurred, nor making assumptions about at which loci these drop-outs might have occurred. The number of alleles that have dropped out, does not need to be exactly known. Here we report a generic Python algorithm to calculate the RMNE probabilities for any given number of loci. The number of allowed drop-outs can be set between 0 and twice the number of analyzed loci. The source code has been made available on https://github.com/fvnieuwe/rmne. An online web-based RMNE calculation tool has been made available on http://forensic.ugent.be/rmne. The tool can calculate these RMNE probabilities from a custom list of probabilities of the observed and non-observed alleles from any given number of loci. Using this tool, we explored the effect of allowing allelic drop-outs on the evidential value of random forensic profiles with a varying number of loci. Our results give insight into how the number of allowed drop-outs affects the evidential value of a profile and how drop-out can be managed in the RMNE approach. Copyright © 2015 The Authors.

    We use unique data to examine how college students from low income families form expectations about academic ability and to examine the role that learning about ability and a variety of other factors play in the college drop-out decision. From the standpoint of satisfying a central implication from the theory of drop-out, we find that self-reported expectations data perform well relative to standard assumptions employed in empirical work when it is necessary to explicitly characterize beliefs...

Surprisingly, not in all such games a VCG payment can be applied to construct a truthful mechanism using an optimal algorithm, though such payments can prevent under-reporting of resources. We show this for the problem of allocating tasks in a social network (STAP).

    In order to obtain reliable accuracy estimates for automatic MOOC dropout predictors, it is important to train and test them in a manner consistent with how they will be used in practice. Yet most prior research on MOOC dropout prediction has measured test accuracy on the same course used for training the classifier, which can lead to overly optimistic accuracy estimates. In order to understand better how accuracy is affected by the training+testing regime, we compared the accuracy of a stand...

    Withdrawal of opioid medication in patients with chronic pain has a drop-out and relapse problem. To evaluate if depressive symptoms, anxiety and pain intensity are potential risk factors for drop-out or relapse during the withdrawal process. Further, to assess internal consistency of scales for assessment of these potential risk factors. Twenty-nine patients were included. After 2 years 28 of these were followed-up. Those with depressive symptoms at baseline had a significant risk for drop-out from the withdrawal program (odds ratio 1.37) and relapse into use of opioids at follow-up (odds ratio 1.44). Drop-outs rated depressive symptoms significantly higher before detoxification. Those who relapsed rated significantly higher for pain intensity, depressive symptoms and abstinence prior to withdrawal. All scales had high reliability. To avoid drop-out and relapse clinical practice need to screen for depressive symptoms, pain intensity, and abstinence. This article presents significant reliability of scales useful within dependency centers. They can be used to identify these risk factors for drop-out and relapse, respectively, when initiating the withdrawal process. Taking these risk factors into consideration could improve the outcome of the withdrawal process by preventing drop-out and relapse.

    Full Text Available Objective: To evaluate the dropout of a multidisciplinary treatment program in fibromyalgia (FM. Methods: An observational study conducted during the period of April 2000 to December 2005, including 133 women with fibromyalgia, participating in a multidisciplinary treatment program. Those who had left the treatment for two weeks or more were classified as inactive and contacted by telephone to record the reasons for their noncompliance, which were divided into four groups: 1 Family; 2 Occupations; 3 Medical; 4 Other Reasons. Results: When collecting data, 92 (69.4% women were considered inactive. There was no significant difference between noncompliance before and after six months of treatment. Of the total number of inactive women, 54 (40.8% participants left for medical reasons, 30 (22.6% for other reasons, 26 (19.4% for family reasons and 23 (17.2% due to occupation. There was no statistical difference between the motives of dropout according to the length of stay in the program (p> 0.05. Conclusion: We conclude that the multidisciplinary program for women with fibromyalgia had high levels of noncompliance, half of them occurred in the first six months. Among the main reasons reported for dropout, the medical reasons were more frequent.

    Full Text Available To explore the frequency and weight that psychosocial risk factors predispose to outcomes of early pregnancy and scholar dropout, a descriptive review was conducted. Materials and Meth­ods: A search and review of the results reported by observational studies in the PubMed data­base indexed from July 27, 2010 until July 25, 2013 was performed, restricting the search to studies in humans, Spanish or English written, not made in countries in Africa or Asia. Search was widened to LILACS database for the years 2006 to 2013 for Latinamerican countries. For inclusion, all case-control studies comparing different types of interventions and psychosocial risk factors in adolescents were eligible. Results: The review suggests violence experienced dur­ing adolescence, sexual abuse, belonging to a low socioeconomic status, low self-esteem, eating behavior disorders, smoking, alcoholism and drug addiction, mental disorders, early initiation of sex, poor family ties, lack of access to information, and resources for family planning as main psychosocial factors related to early pregnancy and scholar dropout in adolescents. Conclusions: Both risk factors associated with pregnancy and scholar dropout were described, and interven­tions targeting the described risk factors could potentially contribute to the reduction of these outcomes were described.

    The evolution of high redshift galaxies in the two Hubble Deep Fields, HDF-N and HDF-S, is investigated using a cloning technique that replicates z~ 2-3 U dropouts to higher redshifts, allowing a comparison with the observed B and V dropouts at higher redshifts (z ~ 4-5). We treat each galaxy selected for replication as a set of pixels that are k-corrected to higher redshift, accounting for resampling, shot-noise, surface-brightness dimming, and the cosmological model. We find evidence for size evolution (a 1.7x increase) from z ~ 5 to z ~ 2.7 for flat geometries (Omega_M+Omega_LAMBDA=1.0). Simple scaling laws for this cosmology predict that size evolution goes as (1+z)^{-1}, consistent with our result. The UV luminosity density shows a similar increase (1.85x) from z ~ 5 to z ~ 2.7, with minimal evolution in the distribution of intrinsic colors for the dropout population. In general, these results indicate less evolution than was previously reported, and therefore a higher luminosity density at z ~ 4-5 (~ 50...

    School dropout and child marriage are interrelated outcomes that have an enormous impact on adolescent girls. However, the literature reveals gaps in the empirical evidence on the link between child marriage and the dropout of girls from school. This study identifies the ‘tipping point’ school grades in Nepal when the risk of dropout due to marriage is highest, measures the effect of child marriage on girls’ school dropout rates, and assesses associated risk factors. Weighted percentages were calculated to examine the grades at highest risk and the distribution of reasons for discontinuing school. Using the Nepal Multiple Indicator Cluster Survey (MICS) 2014 data, we estimated the effect of marriage on school attendance and dropout among girls aged 15–17 by constructing logistic regression models. A multivariate logistic regression model was used to assess risk factors of school dropout due to child marriage. It was found that early marriage is the most common reason given for leaving school. Overall, the risk of school dropout due to marriage heightens after girls complete the fifth or sixth grade. The risk of girls’ dropping out peaks in the seventh and eighth grades and remains noteworthy in the ninth and tenth grades. Married girls in Nepal are 10 times more likely to drop out than their unmarried peers. Little or no education of the household head, belonging to the Kirat religion, and membership of a traditionally disadvantaged social class each elevate the risk of school dropout due to early marriage. The findings underscore the need to delay girl’s marriage so as to reduce girls’ school dropout in Nepal. School-based programmes aimed at preventing child marriage should target girls from the fifth grade because they are at increased risk of dropping out, as well as prioritizing girls from disadvantaged groups.

    This Report summarizes the waste generation and pollution prevention activities of the major operational sites in the Department of Energy (DOE). We are witnessing progress in waste reduction from routine operations that are the focus of Department-wide reduction goals set by the Secretary on May 3,1996. The goals require that by the end of 1999, we reduce, recycle, reuse, and otherwise avoid waste generation to achieve a 50 percent reduction over 1993 levels. This Report provides the first measure of our progress in waste reduction and recycling against our 1993 waste generation baseline. While we see progress in reducing waste from our normal operations, we must begin to focus attention on waste generated by cleanup and facilities stabilization activities that are the major functions of the Office of Environmental Management. Reducing the generation of waste is one of the seven principles that I have established for the Office of Environmental Management Ten Year Plan. As part of our vision to complete a major portion of the environmental cleanup at DOE sites over the next ten years, we must utilize the potential of the pollution prevention program to reduce the cost of our cleanup program. We have included the Secretarial goals as part of the performance measures for the Ten Year Plan, and we are committed to implementing pollution prevention ideas. Through the efforts of both Federal and contractor employees, our pollution prevention program has reduced waste and the cost of our operations. I applaud their efforts and look forward to reporting further waste reduction progress in the next annual update of this Report.

    This seventh Annual Report presents and analyzes DOE Complex-wide waste generation and pollution prevention activities at 45 reporting sites from 1993 through 1998. This section summarizes Calendar Year 1998 Complex-wide waste generation and pollution prevention accomplishments. More detailed information follows this section in the body of the Report. In May 1996, the Secretary of Energy established a 50 percent Complex-Wide Waste Reduction Goal (relative to the 1993 baseline) for routine operations radioactive, mixed, and hazardous waste generation, to be achieved by December31, 1999. DOE has achieved its Complex-Wide Waste Reduction Goals for routine operations based upon a comparison of 1998 waste generation to the 1993 baseline. Excluding sanitary waste, routine operations waste generation decreased 67 percent overall from 1993 to 1998. However, for the first time since 1994, the total amount of materials recycled by the Complex decreased from 109,600 metric tons in 1997 to 92,800 metric tons in 1998. This decrease is attributed to the fact that in 1997, several large ''one-time only'' recycling projects were conducted throughout the Complex. In order to demonstrate commitment to DOE's Complex-wide recycling goal, it is important for sites to identify all potential large-scale recycling/reuse opportunities.

Data from the NSW Notifiable Conditions Information Management System were analysed by: local health district of residence, age, Aboriginality, vaccination status and organism, where available. Risk factor and vaccination status data were collected by public health units for cases following notification under the NSW Public Health Act 2010. The largest outbreak of measles since 1998 was reported in 2012. Pacific Islander and Aboriginal people were at higher risk as were infants less than 12 months of age. Notifications of invasive pneumococcal disease (IPD in children less than five years declined; however, the overall number of notifications for IPD increased. Mumps case notifications were also elevated. There were no Haemophilus influenzae type b case notifications in children less than five years of age for the first time since the vaccine was introduced. Invasive meningococcal disease case notifications were at their lowest rates since case notification began in 1991. Case notification rates for other selected vaccine-preventable diseases remained stable. Vaccine-preventable disease control is continually strengthening in NSW with notable successes in invasive bacterial infections. However, strengthening measles immunization in Pacific Islander and Aboriginal communities remains essential to maintain measles elimination.

    2014-08-19

    There are high attrition rates observed in efficacy studies for social anxiety disorder, and research has not identified consistent nor theoretically meaningful predictors of dropout. Pre-treatment symptom severity and demographic factors, such as age and gender, are sometimes predictive of dropout. The current study examines a theoretically meaningful predictor of attrition based on experiences associated with social group membership rather than differences between social group categories--fear of confirming stereotypes. This is a secondary data analysis of a randomized controlled trial comparing two cognitive behavioral treatments for social anxiety disorder: virtual reality exposure therapy and exposure group therapy. Participants (N = 74) with a primary diagnosis of social anxiety disorder who were eligible to participate in the parent study and who self-identified as either "African American" (n = 31) or "Caucasian" (n = 43) completed standardized self-report measures of stereotype confirmation concerns (SCC) and social anxiety symptoms as part of a pre-treatment assessment battery. Hierarchical logistic regression showed that greater stereotype confirmation concerns were associated with higher dropout from therapy--race, age, gender, and pre-treatment symptom severity were not. Group treatment also was associated with higher dropout. These findings urge further research on theoretically meaningful predictors of attrition and highlight the importance of addressing cultural variables, such as the experience of stereotype confirmation concerns, during treatment of social anxiety to minimize dropout from therapy.

    Participant drop-out occurs in all longitudinal studies, and if systematic, may lead to selection biases and erroneous conclusions being drawn from a study. We investigated whether drop out in the Avon Longitudinal Study of Parents And Children (ALSPAC) was systematic or random, and if systematic, whether it had an impact on the prediction of disruptive behaviour disorders. Teacher reports of disruptive behaviour among currently participating, previously participating and never participating children aged 8 years in the ALSPAC longitudinal study were collected. Data on family factors were obtained in pregnancy. Simulations were conducted to explain the impact of selective drop-out on the strength of prediction. Drop out from the ALSPAC cohort was systematic and children who dropped out were more likely to suffer from disruptive behaviour disorder. Systematic participant drop-out according to the family variables, however, did not alter the association between family factors obtained in pregnancy and disruptive behaviour disorder at 8 years of age. Cohort studies are prone to selective drop-out and are likely to underestimate the prevalence of psychiatric disorder. This empirical study and the simulations confirm that the validity of regression models is only marginally affected despite range restrictions after selective drop-out.

    2010-05-01

    Full Text Available Abstract Background Parents are the ones who decide whether or not to participate in parent focused prevention trials. Their decisions may be affected by internal factors (e.g., personality, attitudes, sociodemographic characteristics or external barriers. Some of these barriers are study-related and others are intervention-related. Internal as well as external barriers are especially important at the screening stage, which aims to identify children and families at risk and for whom the indicated prevention programs are designed. Few studies have reported their screening procedure in detail or analyzed differences between participants and dropouts or predictors of dropout. Rates of participation in prevention programs are also of interest and are an important contributor to the efficacy of a prevention procedure. Methods In this study, we analyzed the process of parent recruitment within an efficacy study of the indicated Prevention Program for Externalizing Problem behavior (PEP. We determined the retention rate at each step of the study, and examined differences between participants and dropouts/decliners. Predictors of dropout at each step were identified using logistic regression. Results Retention rates at the different steps during the course of the trial from screening to participation in the training ranged from 63.8% (pre-test to 81.1% (participation in more than 50% of the training sessions. Parents who dropped out of the study were characterized by having a child with lower symptom intensity by parent rating but higher ratings by teachers in most cases. Low socioeconomic status and related variables were also identified as predictors of dropout in the screening (first step and for training intensity (last step. Conclusions Special attention should be paid to families at increased risk for non-participation when implementing the prevention program in routine care settings. Trial Registration ISRCTN12686222

    Although numerous reports have shown that the use of icodextrin solution, as compared with conventional dextrose solutions, provides various clinical benefits, data on the impact of icodextrin solution on mortality and drop-out are sparse. In the present retrospective study, we compared clinical outcomes in a large cohort of patients prescribed either icodextrin or dextrose solution for the long dwell. A total of 7808 patients across Japan who were using Baxter peritoneal dialysis (PD) solutions in 2004 were included in this cross-sectional analysis. Outcomes data were retrieved from the Baxter Japan database. The annual drop-out rate in the icodextrin group (8.9%) was significantly (p icodextrin group, regardless of PD duration, was consistently lower than that in hemodialysis patients. These results indicate that, in PD, the use of icodextrin solution (as compared with dextrose solution) significantly reduces both mortality and drop-out rate.

    Familial searching, the act of searching a database for a relative of an unknown individual whose DNA profile has been obtained, is usually restricted to cases where the DNA profile of that person has been unambiguously determined. Therefore, it is normally applied only with a good quality single source profile as starting point. In this article we investigate the performance of the method if applied to mixtures with and without allelic dropout, when likelihood ratios are computed with a semi-continuous (binary) model. We show that mixtures with dropout do not necessarily perform worse than mixtures without, especially if some separation between the donors is possible due to their different dropout probabilities. The familial searching true and false positive rates of mixed profiles on 15 loci are in some cases better than those of single source profiles on 10 loci. Thus, the information loss due to the fact that the person of interest's DNA has been mixed with that of other, and is affected by dropout, can be less than the loss of information corresponding to having 5 fewer loci available for a single source trace. Profiles typed on 10 autosomal loci are often involved in familial searching casework since many databases, including the Dutch one, in part consist of such profiles. Therefore, from this point of view, there seems to be no objection to extend familial searching to mixed or degraded profiles.

    There is little available information on the factors that influence relapses and dropouts during therapy for pathological gambling (PG). The aim of this study was to determine socio-demographic, clinical, personality, and psychopathological predictors of relapse and dropout in a sample of pathological gamblers seeking treatment. A total of 566 consecutive outpatients diagnosed with PG according to DSM-IV-TR criteria were included. All patients underwent an individualized cognitive-behavioral treatment program. We analyzed predictors of relapse during 6months of treatment and during the subsequent 6months of follow-up, and predictors of dropout over the entire therapeutic program. Eighty patients (14.1%) experienced at least one relapse during the entire follow-up of the study: 50 (8.8%) within the treatment period and 12 (2.1%) during the subsequent 6-month follow-up period. The main predictors of relapse were single marital status, spending less than 100euros/week on gambling, active gambling behavior at treatment inclusion, and high scores on the TCI-R Harm Avoidance personality dimension. One hundred fifty-seven patients (27.8%) missed 3 or more therapeutic sessions over the entire therapeutic program. The main predictors of dropout were single marital status, younger age, and high scores on the TCI-R Novelty Seeking personality dimension. The presence of these factors at inclusion should be taken into account by physicians dealing with PG patients. Copyright © 2014 Elsevier Inc. All rights reserved.

  3. Understanding Why Students Drop Out of High School, According to Their Own Reports

    Directory of Open Access Journals (Sweden)

    2013-10-01

    Full Text Available Research on school dropout extends from early 20th-century pioneers until now, marking trends of causes and prevention. However, specific dropout causes reported by students from several nationally representative studies have never been examined together, which, if done, could lead to a better understanding of the dropout problem. Push, pull, and falling out factors provide a framework for understanding dropouts. Push factors include school-consequence on attendance or discipline. Pull factors include out-of-school enticements like jobs and family. Finally, falling out factors refer to disengagement in students not caused by school or outside pulling factors. Since 1966, most nationally representative studies depicted pull factors as ranking the highest. Also, administrators in one study corroborated pull out factors for younger dropouts, not older ones, while most recent research cites push factors as highest overall. One rationale for this change is a response to rising standards from No Child Left Behind (NCLB, which can be ultimately tested only by future dropout research.

  9. Annual report of waste generation and pollution prevention progress 1997

    1998-09-01

    This sixth Annual Report presents and analyzes DOE Complex-wide waste generation and pollution prevention activities at 36 reporting sites from 1993 through 1997. In May 1996, the Secretary of Energy established a 50 percent Complex-Wide Waste Reduction Goal (relative to the 1993 baseline) for routine operations radioactive and hazardous waste generation, to be achieved by December 31, 1999. Excluding sanitary waste, routine operations waste generation increased three percent from 1996 to 1997, and decreased 61 percent overall from 1993 to 1997. DOE has achieved its Complex-Wide Waste Reduction Goals for routine operations based upon a comparison of 1997 waste generation to the 1993 baseline. However, it is important to note that increases in low-level radioactive and low-level mixed waste generation could reverse this achievement. From 1996 to 1997, low-level radioactive waste generation increased 10 percent, and low-level mixed waste generation increased slightly. It is critical that DOE sites continue to reduce routine operations waste generation for all waste types, to ensure that DOE`s Complex-Wide Waste Reduction Goals are achieved by December 31, 1999.

  10. Determinants of Voluntary National Health Insurance Drop-Out in Eastern Sudan.

    Science.gov (United States)

    Herberholz, Chantal; Fakihammed, Wael Ahmed

    2017-04-01

    Low enrolment and high drop-out rates are common problems in voluntary health insurance schemes. Yet, most studies in this research area focus on community-based health insurance and enrolment, rather than drop-out. This study examines what causes informal sector families not to renew their voluntary National Health Insurance Fund (NHIF) health insurance membership in Eastern Sudan. Primary data from about 600 informal sector households that dropped out or remained insured, collected through a household survey conducted in March 2014, were used. Logistic regressions were employed to examine what determines drop-out of the voluntary NHIF scheme. The logistic regression results are consistent with the existing literature and confirm the importance of household head, household and community characteristics. Notably, worse family health status and higher health care utilization decrease the probability of drop-out, which requires further analysis as it may indicate the problem of adverse selection and insufficient risk management. Most importantly, the results consistently show that household heads who are satisfied with health services and those who understand the main features of the voluntary NHIF scheme are less likely to drop out. Also, 30 % of drop-out households hold a social support card and reported that the social support scheme is the main reason for not renewing their voluntary NHIF health insurance membership as they qualify for sponsored NHIF health insurance membership. This study shows that satisfaction with health services and knowledge of the health insurance scheme are important factors explaining drop-out of a national health insurance programme. The results suggest that education and information campaigns should be developed further to raise understanding of the NHIF voluntary scheme. In addition, information systems and coordination between the main agencies should be strengthened to reduce administrative costs and ensure policy coherence.

    Completion of addiction treatment is one of the most consistent factors associated with a favorable treatment outcome. Unfortunately, it is more common for a patient to drop-out of addiction treatment than to complete the treatment. To prevent drop-out, risk factors must be identified. This box-score review focuses on studies investigating the risk factors associated with drop-out from addiction treatment published in peer-reviewed journals from 1992 to 2013. A total of 122 studies involving 199,331 participants met the inclusion criteria. Contrary to recommendations from previous reviews, 91% of the included studies focused primarily on enduring patient factors, mainly demographics. The most consistent risk factors across the different study designs, samples, and measurement methods were cognitive deficits, low treatment alliance, personality disorder, and younger age. With the exception of younger age, none of the demographic factors emerged as consistent risk factors. Further research on the relationship between simple demographic factors and drop-out risk is of limited value. However, little is known about the potential risk factors related to treatment programs and to the treatment processes. Based on the review, clinical recommendations include assessing cognitive functioning and personality disorders at baseline and continuous monitoring of treatment alliance.

  12. Identifying potential dropouts from college physics classes

    Science.gov (United States)

    Wollman, Warren; Lawrenz, Frances

    Hudson and Rottman (1981) established that mathematics ability is probably a secondary factor influencing dropout from college physics courses. Other factors remain to be found for predicting who will drop out or at least have difficulty with the course. When mathematics ability is coupled with general indicators of performance (total GPA and ACT natural science), prediction of performance for those who complete the course is substantially improved. Moreover, discriminant analyses reveal who will have at least some difficulty, but not who will drop out. The problem of isolating specific weaknesses of students who have difficulty persists. Physics achievement appears to depend on mathematics ability only to the extent that students possess the ability to utilize mathematics knowledge for solving physics problems. Identification of the specific aspects of this ability as well as the specific deficiencies leading to dropout should be the object of future research. For the present, interviews might be more revealing than group testing methods.

    Non-response and drop-out are problems that are commonly encountered in health promotion trials. Understanding the health-related characteristics of non-participants and drop-outs and the reasons for non-participation and drop-out may be beneficial for future intervention trials. Male construction workers with an elevated risk of cardiovascular disease (CVD) were invited to participate in a lifestyle intervention study. In order to investigate the associations between participation and CVD risk factors, and drop-out and CVD risk factors, crude and multiple logistic regression analyses were performed. The reasons for non-participation and drop-out were assessed qualitatively. 20% of the workers who were invited decided to participate; 8.6% of the participants dropped out before the first follow-up measurement. The main reasons for non-participation were 'no interest', 'current (para-)medical treatment', and 'feeling healthy', and for drop-out they were 'lack of motivation', 'current (para-)medical treatment', and 'disappointment'. Participants were 4.2 years older, had a higher blood pressure, higher total cholesterol, and lower HDL cholesterol than non-participants, and were more likely to report 'tiredness and/or stress' and 'chest pain and/or shortness of breath'. After adjusting for age, most risk factors were not significantly associated with participation. Drop-outs were 4.6 years younger than those who completed the study. The prevalence of smoking was higher among non-participants and drop-outs. Participants had a worse CVD risk profile than non-participants, mainly because of the difference in age. Non-participants and drop-outs were younger and more likely to be smokers. The main reasons for non-participation and drop-out were health-related. Investigators in the field of health promotion should be encouraged to share comparable information. Current Controlled Trials ISRCTN60545588.

    The prevention and treatment of overweight and obese individuals on a population-wide basis is challenging because patients have difficulties with adhering to weight loss programmes. The present study aimed to evaluate patients' adherence to the weight reduction programme by identifying factors predictive of both drop-out rate and weight loss success. One-hundred and twenty-four obese patients participated in a 12-month weight reduction programme, involving group therapy during an intensive 5-day educational intervention, followed by five, 2-h follow-up visits. The primary outcome measures included drop-out rate and percentage weight loss. Sociodemographic and clinical characteristics, as well as type of diet, were explored as potential predictive factors. Type of diet was assigned based on randomisation. Regression analyses were conducted to identify predictive variables of drop-out and weight loss success. In total, 33.1% of all recruited participants were deemed successful because they reduced the initial weight by more than 5% after the 12-month intervention. The overall attrition rate was 32.3%. In a multiple regression model, initial weight loss and marital status were the strongest predictors of weight loss success after 1-year period (r(2) = 0.481, P drop-out were those with a lower educational level [odds ratio (OR) = 3.26, 95% confidence interval (CI) = 1.22-8.70, P = 0.018] and a higher level of obesity (OR = 0.974, 95% CI = 0.95-0.99, P = 0.010). The present study demonstrates that initial weight loss at 1 month made the strongest unique contribution to the prediction of percentage weight loss after 12 months, whereas being married was a negative predictor. Those with a lower educational level and a higher level of obesity were more likely to drop-out. © 2014 The British Dietetic Association Ltd.

    2005-03-01

    Full Text Available Abstract Background Recently, intracardiac echocardiography emerged as a useful tool in the electrophysiology laboratories for guiding transseptal left heart catheterizations, for avoiding thromboembolic and mechanical complications and assessing the ablation lesions characteristics. Although the value of ICE is well known, it is not a universal tool for achieving uncomplicated access to the left atrium. We present a case in which ICE led to interruption of a transseptal procedure because several risk factors for mechanical complications were revealed. Case presentation A case of a patient with paroxysmal atrial fibrillation and atrial flutter, and distorted intracardiac anatomy is presented. Intracardiac echocardiography showed a small oval fossa abouting to an enlarged aorta anteriorly. A very small distance from the interatrial septum to the left atrial free wall was seen. The latter two conditions were predisposing to a complicated transseptal puncture. According to fluoroscopy the transseptal needle had a correct position, but the intracardiac echo image showed that it was actually pointing towards the aortic root and most importantly, that it was virtually impossible to stabilize it in the fossa itself. Based on intracardiac echo findings a decision was made to limit the procedure only to ablation of the cavotricuspid isthmus and not to proceed further so as to avoid complications. Conclusion This case report illustrates the usefulness of the intracardiac echocardiography in preventing serious or even fatal complications in transseptal procedures when the cardiac anatomy is unusual or distorted. It also helps to understand the possible mechanisms of mechanical complications in cases where fluoroscopic images are apparently normal.

  17. Preventing misdiagnosis in amniotic band sequence: a case report

    Directory of Open Access Journals (Sweden)

    Cristiane Rúbia Ferreira

    2013-03-01

    Full Text Available Amniotic band sequence (ABS is an uncommon and heterogeneous congenital disorder caused by entrapment of fetal parts by fibrous amniotic bands, causing distinctive structural abnormalities involving limbs, trunk, and craniofacial regions. The incidence ranges between 1/1200 and 1/15,000 live births, but is higher in stillbirths and previable fetuses. The intrinsic theory attributes the constriction band syndrome as an inherent development defect of embryogenesis while the extrinsic theory proposes that an early amnion rupture is responsible for the adherent bands. It is also suggested that amputations and constriction rings might be due to vascular disturbances. Anomalies resulting from amniotic bands are quite variable and sometimes may simulate chromosomal abnormalities. The authors report a case of a 36-week-gestation male neonate who lived for 29 hours after a vaginal delivery with an Apgar score of 8/9/9. The mother was primipara, and the prenatal was uneventful except for two episodes of urinary tract infections. The newborn examination depicted multiple anomalies characterized by exencephaly, bilateral labial cleft with distorted nostrils and palate cleft. There was also facial skin tag band, exophthalmos with hypoplasia of the eyelids. The limbs showed distal amputation of the fingers in both hands and feet, oligodactyly associated with syndactyly in the left foot, ring constriction in the right leg, the presence of right hyperextension, and clubfoot. The upper limbs showed length discrepancies. Karyotype analysis was normal at 46 XY. The authors conclude that the recognition of the malformations secondary to ABS is important in genetic counseling to prevent misdiagnosis between chromosomal and secondary disruption disorders.

    2010-01-01

    Drop-out is a serious problem in psychotherapy. Earlier studies have shown that the main factors associated with drop-out are young age, low socio-economic status and pathological symptoms such as severity of the problems and problematic substance-abuse. To investigate patient's and pathological characteristics that predict drop-out among patients with predominantly personality problems. Patient's characteristics and pathological characteristics of 372 subjects were ascertained via a retrospective study by means of four databases: intake letters, scid-ii personality questionnaires, scid-i and ii interviews and discharge letters. The association between these characteristics and drop-out was tested by means of bivariate and multivariate analysis. results The drop-out rate was 33.3 %. The main predictors of drop-out were young age, a low Global Assessment of Functioning (gaf)-score and the existence of problematic substance-abuse at discharge. The degree and severity of axis i disorders and the nature of personality problems made hardly any contribution to the prediction of drop-out. These findings indicate that more attention needs to be given to the existence of substance-abuse before psychotherapy begins. Drop-out is still a problem and is difficult to predict and hard to influence.

    28% of students of any one year currently give up their studies in bachelor degree programmes at German higher education institutions. Drop-out is to be understood as the definite termination in the higher education system without obtaining an academic degree. The drop-out rate is thereby calculated with the help of statistical estimation…

    Adverse drug reactions (ADRs) are a major patient safety issue, and a substantial proportion of ADRs are, in fact, preventable. The aim of this study was to describe the proportion and pattern of preventable ADRs in spontaneously reported suspected ADRs and to study the feasibility of using data from an ADR reporting system for this purpose. All reports of ADRs, except those in which a vaccine was the suspected drug, submitted to the regional pharmacovigilance center of southeastern Sweden between 2008 and 2009 were analyzed. Causality between the suspected ADR and the medication was assessed using the World Health Organization (WHO) criteria, and preventability was assessed using Hallas criteria. During the study period, 1,290 ADRs were received and 1,255 were classified as having at least a possible causality between a reaction and a drug. Of these, 172 (14%) ADRs were considered preventable, 35 (20%) were classified as definitely preventable, and 137 (80%) as possibly preventable. Of all preventable ADRs, 96 (56%) were related to prescribing, 35 (20%) to administration, and 41 (24%) to clinical and laboratory monitoring of treatment. Warfarin, oxycodone, and ioversol were the most common drugs with preventable ADRs. This study found that a substantial part of reported ADRs are preventable. Most of these are related to drug prescription, suggesting that interventions aiming to reduce preventable ADRs should focus on this process. Moreover, systems for ADR reporting may be useful in the mission of reducing the unsafe use of drugs.

  12. University Students’ Tendencies Toward and Reasons Behind Dropout

    Full Text Available In this research conducted to investigate university students’ tendencies toward and reasons behind dropout, it was found that university students had a high level of tendency towards dropout (45%. This indicated that one out of two students wanted to drop out of school at least once for a reason. As a result, their tendencies toward dropout was due to personal factors as well as those related to family, friends, and school. The personal factors affecting tendency toward dropout were gender, academic performance, school attendance, out-of-school work, boredom at school, and discipline penalty. According to the results, the factors related to school were faculty type, level of satisfaction with administrative and teaching staff as well as with social activities, level of difficulty in the department, and willingness to choose faculty. Furthermore, in this study, a positive relationship was found between dropout tendency and possession of close friends who dropped out of school.

    This article summarizes the results of a systematic review of randomized controlled trials testing the effectiveness of special beds, mattresses, and cushions in preventing and treating pressure sores. The review's citation is Cullum, N., Deeks, J., Sheldon, T.A., Song, F., & Fletcher, A.W. (2000). Beds, mattresses and cushions for pressure sore prevention and treatment (Cochrane Review). The Cochrane Library, 4. An integrative research review. 37 studies were included in the analysis. A broad search of databases and unpublished studies was conducted. Data were extracted from those that met the inclusion criteria. Studies were grouped in various ways but mainly by type of product evaluated. Many special products designed to prevent or treat pressure sores are more effective than standard hospital foam mattresses in preventing and treating pressure sores. Special pressure-relieving surfaces should be used for patients at risk for skin breakdown. Individual practitioners and agencies should have a systematic protocol for assessing patients' risk of skin breakdown and for taking action when patients are determined to be at risk. The findings of this review provide some guidance for choosing particular products, albeit not definitive evidence for matching risk levels to products.

    Between 30 and 70% of patients with eating disorders drop out from outpatient treatment. However, research has been unable to identify factors that consistently predict dropout from eating disorder treatment. Most studies have exclusively investigated the role that individual patient characteristics play in dropout and have ignored more process-based factors such as expectations about treatment, the therapeutic alliance, or time spent on a treatment waiting list. This study aimed to investigate the roles of both individual patient characteristics and process-based factors in dropout from outpatient treatment for eating disorders. The study involved data collected from consecutive eating disorder referrals to the only public specialist eating disorder service for youth and adults in Perth, Western Australia. The standard treatment provided at this service is Enhanced Cognitive Behaviour Therapy on an individual basis. The study involved 189 patients referred to the service between 2005 and 2010. Forty five percent of this sample dropped out of treatment. Results showed that, in this sample, two individual factors, lowest reported weight and the tendency to avoid affect, and one process-based factor, time spent on the wait list for treatment, were significant predictors of dropout. These findings are valuable because a process-based factor, such as wait-list time, may be easier to address and modify than a patient's weight history or the trait of mood intolerance. Increased resources for eating disorder services may reduce waiting list times which would help to reduce dropout and maximize treatment outcomes.

    1996-11-01

    A comprehensive report mandated by the U.S. Congress on the state of the science of prevention recommends a stricter definition of the term prevention; summarizes specific preventive intervention research programs across the life span; and specifies funding, personnel, and coordination priorities to build a national prevention research infrastructure. A major conceptual recommendation is a focus on reducing risk for mental disorders, which has been a fruitful strategy in the prevention of physical illness. The report argues that the prevention field should also draw from advances in mental disorder treatment research and from the major contributions to the knowledge base occurring in the behavioral and biological core sciences. Relevant advances in neuroscience, genetics, epidemiology, and developmental psychopathology are examined in detail. Five major disorders are chosen to illustrate possible approaches to prevention: conduct disorder, depressive disorders, alcohol abuse and dependence, schizophrenia, and Alzheimer's disease.

  16. The early identification of risk factors on the pathway to school dropout in the SIODO study: a sequential mixed-methods study

    Directory of Open Access Journals (Sweden)

    Theunissen Marie-José

    2012-11-01

    Full Text Available Abstract Background School dropout is a persisting problem with major socioeconomic consequences. Although poor health probably contributes to pathways leading to school dropout and health is likely negatively affected by dropout, these issues are relatively absent on the public health agenda. This emphasises the importance of integrative research aimed at identifying children at risk for school dropout at an early stage, discovering how socioeconomic status and gender affect health-related pathways that lead to dropout and developing a prevention tool that can be used in public health services for youth. Methods/design The SIODO study is a sequential mixed-methods study. A case–control study will be conducted among 18 to 24 year olds in the south of the Netherlands (n = 580. Data are currently being collected from compulsory education departments at municipalities (dropout data, regional public health services (developmental data from birth onwards and an additional questionnaire has been sent to participants (e.g. personality data. Advanced analyses, including cluster and factor analyses, will be used to identify children at risk at an early stage. Using the quantitative data, we have planned individual interviews with participants and focus groups with important stakeholders such as parents, teachers and public health professionals. A thematic content analysis will be used to analyse the qualitative data. Discussion The SIODO study will use a life-course perspective, the ICF-CY model to group the determinants and a mixed-methods design. In this respect, the SIODO study is innovative because it both broadens and deepens the study of health-related determinants of school dropout. It examines how these determinants contribute to socioeconomic and gender differences in health and contributes to the development of a tool that can be used in public health practice to tackle the problem of school dropout at its roots.

    2013-06-01

    Electronic gambling offers the opportunity to analyze huge and unbiased data sets of automatically recorded actual gambling behavior. This study refers to data on 2,127,887 poker playing identities from the Online Poker Database of the University of Hamburg (OPD-UHH) to analyze three subgroups of gamblers: regulars, newcomers, and dropouts. Their gambling habits over 6 months are analyzed in total, as well as over time. Regulars show a much higher involvement than non-regulars and increase their playing volume slightly over the observation period. Newcomers have a lower involvement than non-newcomers and most of them decrease their playing volume over time. Still, there is a small group of newcomers which increases their playing volume sharply and is, hence, very interesting for the industry as well as for the early prevention of pathological gambling. Dropouts have a higher gambling involvement than newcomers but play less than players who have not stopped stop gambling. Most dropouts also show a decreasing playing volume before dropping out. An analysis of the correlations between different variables of gambling habits shows that most of them reinforce each other, for example: gamblers with a higher total playing time tend to play at more tables simultaneously. Only playing frequency is a moderating variable of gambling involvement.

    2004-10-01

    Full Text Available Introduction The objective of this study was to determine the demographic, treatment, clinical, and behavioral factors associated with dropping out of a nurse-based, low-income, multiethnic San Diego diabetes program. Methods Data were collected during a 17-month period in 2000 and 2002 on patients with type 2 diabetes from Project Dulce, a disease management program in San Diego County designed to care for an underserved diabetic population. The study sample included 69 cases and 504 controls representing a racial/ethnic mix of 53% Hispanic, 7% black, 16% Asian, 22% white, and 2% other. Logistic regression was used to determine factors associated with patient dropout. Results Patients who had high initial clinical indicators including blood pressure and hemoglobin A1c and those who smoked currently or smoked in the past were more likely to drop out of the diabetes program. Conclusion This study provides markers of patient dropout in a low-income, multiethnic, type 2 diabetic population. Reasons for dropout in this program can be investigated to prevent further cohort loss.

    Drop-out of addiction treatment is common, however, little is known about drop-out of compulsory care in Sweden. Data from two national register databases were merged to create a database of 4515 individuals sentenced to compulsory care 2001-2009. The study examined (1) characteristics associated with having dropped out from a first compulsory care episode, (2) the relationship between drop-out and returning to compulsory care through a new court sentence, and (3) the relationship between drop-out and mortality. Multivariable logistic regression analysis was used to address Aim 1 and Cox proportional hazards regression modeling was applied to respond to Aims 2 and 3. Age and previous history of crime were significant predictors for drop-out. Clients who dropped out were 1.67 times more likely to return to compulsory care and the hazard of dying was 16% higher than for those who dropped-out. This study finds that 59% of clients assigned to compulsory care drop-out. Younger individuals are significantly more likely to drop-out. Those who drop out are significantly more likely to experience negative outcomes (additional sentence to compulsory care and higher risk of mortality). Interventions need to be implemented that increase motivation of youth to remain in compulsory care. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Dropping out of university has serious consequences not only for the student who drops out but also for the institution and society as a whole. Although this phenomenon has been widely studied, there is a need for broader knowledge of the context in which it occurs. Yet research on the subject often focuses on variables that, although they affect drop-out rates, lie beyond a university's control. This makes it hard to come up with effective preventive measures. That is why a northern Spanish university has undertaken a ex post facto holistic research study on 1,311 freshmen (2008/9, 2009/10, and 2010/11 cohorts). The study falls within the framework of the ALFA-GUIA European Project and focuses on those drop-out factors where there is scope for taking remedial measures. This research explored the possible relationship of degree drop-out and different categories of variables: variables related to the educational stage prior to university entry (path to entry university and main reason for degree choice), variables related to integration and coexistence at university (social integration, academic integration, relationships with teachers/peers and value of the living environment) financial status and performance during university studies (in terms of compliance with the program, time devoted to study, use of study techniques and class attendance). Descriptive, correlational and variance analyses were conducted to discover which of these variables really distinguish those students who drop-out from their peers who complete their studies. Results highlight the influence of vocation as main reason for degree choice, path to university entry, financial independency, social and academic adaptation, time devoted to study, use of study techniques and program compliance in the studied phenomenon.

    2012-01-01

    Full Text Available The convergence of model-free adaptive control (MFAC algorithm can be guaranteed when the system is subject to measurement data dropout. The system output convergent speed gets slower as dropout rate increases. This paper proposes a MFAC algorithm with data compensation. The missing data is first estimated using the dynamical linearization method, and then the estimated value is introduced to update control input. The convergence analysis of the proposed MFAC algorithm is given, and the effectiveness is also validated by simulations. It is shown that the proposed algorithm can compensate the effect of the data dropout, and the better output performance can be obtained.

    Not only source catalogs are extracted from astronomy observations. Their sky coverage is always carefully recorded and used in statistical analyses, such as correlation and luminosity function studies. Here we present a novel method for catalog matching, which inherently builds on the coverage information for better performance and completeness. A modified version of the Zones Algorithm is introduced for matching partially overlapping observations, where irrelevant parts of the data are excluded up front for efficiency. Our design enables searches to focus on specific areas on the sky to further speed up the process. Another important advantage of the new method over traditional techniques is its ability to quickly detect dropouts, i.e., the missing components that are in the observed regions of the celestial sphere but did not reach the detection limit in some observations. These often provide invaluable insight into the spectral energy distribution of the matched sources but rarely available in traditional...

    2015-05-01

    In forensic genetics, a mixture of two or more contributors to a DNA profile is often interpreted using the inclusion probabilities theory. In this paper, we present a general formula for estimating the probability of inclusion (PI, also known as the RMNE probability) from a subset of visible alleles when dropouts are possible. This one-locus formula can easily be extended to multiple loci using the cumulative probability of inclusion. We show that an exact formulation requires fixing the number of contributors, hence to slightly modify the classic interpretation of the PI. We discuss the implications of our results for the enduring debate over the use of PI vs likelihood ratio approaches within the context of low template amplifications.

    The convergence of model-free adaptive control (MFAC) algorithm can be guaranteed when the system is subject to measurement data dropout. The system output convergent speed gets slower as dropout rate increases. This paper proposes a MFAC algorithm with data compensation. The missing data is first estimated using the dynamical linearization method, and then the estimated value is introduced to update control input. The convergence analysis of the proposed MFAC algorithm is given, and the effe...

    2012-01-01

    Research examining the educational attainment of low-income students has often focused on financial factors such as credit constraints. We use unique longitudinal data to provide direct evidence about a prominent alternative explanation--that departures from school arise as students learn about their academic ability or grade performance. Examining college dropout, we find that this explanation plays a very prominent role; our simulations indicate that dropout between the first and second yea...

  9. School dropout susceptibility mapping with fuzzy logic – a study in the District of Purulia, India

    Full Text Available Multi-input prediction models are gradually finding their places in the arena of social and economic sciences to assess, locate and address the complicated socio-economic issues arising around the globe. These models treat the problems as the output aroused from a complex interaction between a range of variables linked with physical, socio-cultural, economic as well as ambient political systems. The discussion on dropout from the education system belongs to the core of the educational researchers. The researchers within this domain are attempting to develop the ‘tools and techniques’ for efficiently demarcating the space with a given degree of susceptibility. The scope is to drop out and examine the internal functions of the interactive variables associated with the process. In the present study, we try to apply the fuzzy logic in mapping the spatial variation of the susceptibility of school dropout in the district of Purulia, a backwards district in India regarding achieved level of human development. The training datasets for building the fuzzy model based on the available secondary data from different reports published by the Government and a range of primary data collected through a socio-economic survey. The model output is an index, namely the Index of Susceptibility of School Drop Out (ISDO which reflects the levels of susceptibility to school dropout at different parts of the study area. The proposed model should allow the success within the larger social and economic system.

    To explore the cause for allelic drop-out at short tandem repeat (STR) loci upon paternity testing with a PowerPlex® 16 kit. A total of 10 642 DNA confirmed paternity testing cases (18 314 parent/child allelic transfers) were analyzed with the PowerPlex® 16 kit. Samples suspected for having allelic drop-out were verified with an Identifiler™ kit and/or locus-specific singleplex amplification systems. PCR products of null alleles were separated and directly sequenced. Eight cases of allelic drop-out were found. The overall rate of null allele in the PowerPlex® 16 system was 0.437 × 10(-3). DNA sequencing has confirmed single base variations within the binding region of published primers, in which 4 cases involved the D18S51 locus (2 cases with G>A transitions at 79 bp upstream of the repeats, 1 case with G>T transversion at 162 bp downstream of the repeats and 1 case with G>C transversion at 74 bp upstream of the repeats), 2 cases involved the D21S11 locus (1 case with C>A transversion at 17 bp upstream of the repeats and 1 case with A>G transition at 12 bp upstream of the repeats). One case involved the FGA locus (1 case with G>A transition at 142 bp downstream of the repeats) and 1 case involved TPOX locus (1 case with G>A transition at 198 bp downstream of the repeats). Base variation in the primer binding region may cause failed PCR and result in null allele reports. Alternative primer sets should be used to verify the suspected allelic drop-out. Attention should be paid to this during paternity testing and data exchange for personal identification.

    On 23 November 2012, a sudden dropout of the relativistic electron flux was observed after an interplanetary shock arrival. The dropout peaks at ˜1 MeV and more than 80% of the electrons disappeared from the drift shell. Van Allen twin Probes observed a sharp electron flux dropout with clear energy dispersion signals. The repeating flux dropout and recovery signatures, or "dropout echoes", constitute a new phenomenon referred to as a "drifting electron dropout" with a limited initial spatial range. The azimuthal range of the dropout is estimated to be on the duskside, from ˜1300 to 0100 LT. We conclude that the shock-induced electron dropout is not caused by the magnetopause shadowing. The dropout and consequent echoes suggest that the radial migration of relativistic electrons is induced by the strong dusk-dawn asymmetric interplanetary shock compression on the magnetosphere.

  12. Baseline participant characteristics and risk for dropout from ten obesity randomized controlled trials: a pooled analysis of individual level data

    2014-12-01

    Full Text Available Introduction: Understanding participant demographic characteristics that inform the optimal design of obesity RCTs have been examined in few studies. The objective of this study was to investigate the association of individual participant characteristics and dropout rates (DORs in obesity randomized controlled trials (RCT by pooling data from several publicly available datasets for analyses. We comprehensively characterize DORs and patterns in obesity RCTs at the individual study level, and describe how such rates and patterns vary as a function of individual-level characteristics. Methods: We obtained and analyzed nine publicly-available, obesity RCT datasets that examined weight loss or weight gain prevention as a primary or secondary endpoint. Four risk factors for dropout were examined by Cox proportional hazards including sex, age, baseline BMI, and race/ethnicity. The individual study data were pooled in the final analyses with a random effect for study, and HR and 95% CIs were computed. Results: Results of the multivariate analysis indicated that the risk of dropout was significantly higher for females compared to males (HR= 1.24, 95% CI = 1.05, 1.46. Hispanics and Non-Hispanic blacks had a significantly higher dropout rate compared to non-Hispanic whites (HR= 1.62, 95% CI = 1.37, 1.91; HR= 1.22, 95% CI = 1.11, 1.35, respectively. There was a significantly increased risk of dropout associated with advancing age (HR= 1.02, 95% CI = 1.01, 1.02 and increasing BMI (HR= 1.03, 95% CI = 1.03, 1.04. Conclusion/Significance: As more studies may focus on special populations, researchers designing obesity RCTs may wish to oversample in certain demographic groups if attempting to match comparison groups based on generalized estimates of expected dropout rates, or otherwise adjust a priori power estimates. Understanding true reasons for dropout may require additional methods of data gathering not generally employed in obesity RCTs, e.g. time on

  15. High school dropouts: interactions between social context, self-perceptions, school engagement, and student dropout.

    Fall, Anna-Mária; Roberts, Greg

    2012-08-01

    Research suggests that contextual, self-system, and school engagement variables influence dropping out from school. However, it is not clear how different types of contextual and self-system variables interact to affect students' engagement or contribute to decisions to dropout from high school. The self-system model of motivational development represents a promising theory for understanding this complex phenomenon. The self-system model acknowledges the interactive and iterative roles of social context, self-perceptions, school engagement, and academic achievement as antecedents to the decision to dropout of school. We analyzed data from the Education Longitudinal Study of 2002-2004 in the context of the self-system model, finding that perception of social context (teacher support and parent support) predicts students' self-perceptions (perception of control and identification with school), which in turn predict students' academic and behavioral engagement, and academic achievement. Further, students' academic and behavioral engagement and achievement in 10th grade were associated with decreased likelihood of dropping out of school in 12th grade.

    Path analysis was used to test a theoretical model of college nursing student dropouts. Multiple regression was used to assess the relative importance of the predictor variables. Students' self-reported reasons for dropping out were studied by contingency and correlational analyses to determine the relationship between these reasons and individual difference variables. Factor analysis was used to develop scales to measure the variables of locus of control, self-esteem, social integration, and institutional commitment. The sample of students was drawn from the National Longitudinal Study of the High School Class of 1972. Included in the sample were students entering two- and four-year nursing programs full-time in the fall of 1972. These two groups of students were found to be significantly different in measures of cognitive ability and in aspirations for further education. Approximately 27 percent of the two-year and 41 percent of the four-year students withdrew from their nursing programs during this study. Reasons for withdrawal most frequently cited by both groups related to losing interest in nursing and becoming interested in other fields of study. Educational aspirations had the strongest direct effect on persistence in nursing for two-year students; for four-year students, academic ability was the most powerful predictor of persistence.

  18. A Review of Recruitment, Adherence and Drop-Out Rates in Omega-3 Polyunsaturated Fatty Acid Supplementation Trials in Children and Adolescents.

    The influence of n-3 long-chain polyunsaturated fatty acids (n-3 LCPUFA) supplementation on health outcomes has been studied extensively with randomized controlled trials (RCT). In many research fields, difficulties with recruitment, adherence and high drop-out rates have been reported. However, what is unknown is how common these problems are in n-3 LCPUFA supplementation studies in children and adolescents. Therefore, this paper will review n-3 LCPUFA supplementation studies in children and adolescents with regard to recruitment, adherence and drop-out rates. The Web of Science, PubMed and Ovid databases were searched for papers reporting on RCT supplementing children and adolescents (2-18 years) with a form of n-3 LCPUFA (or placebo) for at least four weeks. As a proxy for abiding to CONSORT guidelines, we noted whether manuscripts provided a flow-chart and provided dates defining the period of recruitment and follow-up. Ninety manuscripts (reporting on 75 studies) met the inclusion criteria. The majority of the studies did not abide by the CONSORT guidelines: 55% did not provide a flow-chart, while 70% did not provide dates. The majority of studies provided minimal details about the recruitment process. Only 25 of the 75 studies reported an adherence rate which was on average 85%. Sixty-five of the 75 studies included drop-out rates which were on average 17%. Less than half of the included studies abided by the CONSORT guidelines (45% included a flow chart, while 30% reported dates). Problems with recruitment and drop-out seem to be common in n-3 LCPUFA supplementation trials in children and adolescents. However, reporting about recruitment, adherence and dropout rates was very heterogeneous and minimal in the included studies. Some techniques to improve recruitment, adherence and dropout rates were identified from the literature, however these techniques may need to be tailored to n-3 LCPUFA supplementation studies in children and adolescents.

    2012-04-01

    Full Text Available In the last two decades, number of Engineering Institutes and Universities grows rapidly in India. This causes a tight competition among these institutions and Universities while attracting the student to get admission in these Institutions/Universities. Most of the institutions and courses opened in Universities are in self finance mode, so all time they focused to fill all the seats of the courses not on the quality of students. Therefore a large number of students drop the course after first year. This paper presents a data mining application to generate predictive models for student’s dropout management of Engineering. Given new records of incoming students, the predictive model can produce accurate prediction list identifying students who tend to need the support from the student dropout program most. The results show that the machine learning algorithm is able to establish effective predictive model from the existing student dropout data.

    Pemberton, S.

    1996-02-01

    The Department of Energy and its contractors are faced with environmental concerns and large waste management costs. Federal legislation and DOE Orders require sites to develop waste minimization/pollution prevention programs. In response to these requirements, the Kansas City Plant developed a pollution prevention tool called a pollution prevention opportunity assessment (PPOA). Pilot assessments resulted in the development of a graded approach to reduce the amount of effort required for activities that utilized nonhazardous and/or low-volume waste streams. The project`s objectives in FY95 were to validate DOE`s PPOA Graded Approach methodology, provide PPOA training and technical assistance to interested DOE personnel and DOE contractors, enhance the methodology with energy analysis and tools for environmental restoration activities, implement a DOE-wide PPOA database, and provide support to DOE EM-334 in the completion of a report which estimates the future potential for pollution prevention and waste minimization in the DOE complex.

    Full Text Available Dropping out of university has serious consequences not only for the student who drops out but also for the institution and society as a whole. Although this phenomenon has been widely studied, there is a need for broader knowledge of the context in which it occurs. Yet research on the subject often focuses on variables that, although they affect drop-out rates, lie beyond a university's control. This makes it hard to come up with effective preventive measures. That is why a northern Spanish university has undertaken a ex post facto holistic research study on 1,311 freshmen (2008/9, 2009/10 and 2010/11 cohorts. The study falls within the framework of the ALFA-GUIA European Project and focuses on those drop-out factors where there is scope for taking remedial measures. This research explored the possible relationship of degree dropout and different categories of variables: variables related to the educational stage prior to university entry (path to entry university and main reason for degree choice, variables related to integration and coexistence at university (social integration, academic integration, relationships with teachers/ peers and value of the living environment financial status and performance during university studies (in terms ofcompliance with the program, time devoted to study, use of study techniques and class attendance. Descriptive, correlational and variance analyses were conducted to discover which of these variables really distinguish those students who drop out from their peers who complete their studies. Results highlight the influence of vocation as main reason for degree choice, path to university entry, financial independency, social and academic adaptation, time devoted to study, use of study techniques and program compliance in the studied phenomenon.

    By both fractal (D1) and branching (Lv) analysis, macular arterial density oscillated with progression from mild NPDR to PDR. Results are consistent with out study reported recently for the entire arterial and venous branching trees within 50 degree FAs by VESGEN generational branching analysis. Current and previous results are important for advances in early-stage regenerative DR therapies, for which reversal of DR progression to a normal vessel density may be possible. For example, potential use of regenerative angiogenesis stimulators to reverse vascular dropout during mild and severe NPDR is not indicated for treatment of moderate NPDR.

    Recent systematic reviews and empirical evaluations of the cognitive sciences literature suggest that publication and other reporting biases are prevalent across diverse domains of cognitive science. In this review, we summarize the various forms of publication and reporting biases and other questionable research practices, and overview the available methods for probing into their existence. We discuss the available empirical evidence for the presence of such biases across the neuroimaging, animal, other preclinical, psychological, clinical trials, and genetics literature in the cognitive sciences. We also highlight emerging solutions (from study design to data analyses and reporting) to prevent bias and improve the fidelity in the field of cognitive science research.

  3. Convergence Analysis of Wireless Remote Iterative Learning Control Systems with Dropout Compensation

    Full Text Available The wireless remote iterative learning control (ILC system with random data dropouts is considered. The data dropout is viewed as a binary switching sequence which obeys the Bernoulli distribution. In order to eliminate the effect of data dropouts on the convergence property of output error, the signal at the same time with the lost one but in the last iteration is used to compensate the data dropout at the actuator. With the dropout compensation, the convergence property of output error is analyzed by studying the element values of system transition matrix. Finally, some simulation results are given to illustrate the validity of the proposed method.

    Roso-Bas, Fátima; Pades Jiménez, Antonia; García-Buades, Esther

    2016-02-01

    The dropout of university studies is a main concern in many countries, also for Health Sciences degrees. The reviews on dropout in all university degrees as well as nursing generally show multidimensional causes with factors related both to institutional and students' characteristics. Regarding the personal variables of students, researchers have focused on financial, family and personality features. Far less attention has been devoted to emotional variables. This study aims to explore whether individual variables of the emotional domain such as perceived emotional intelligence, dispositional optimism/pessimism and depressive rumination are related and/or can predict students' intention to dropout and academic performance. Using a cross-correlational approach, data were obtained from a sample of 144 nursing students. Students with a pessimistic disposition revealed a greater tendency to drop out. The remaining variables correlated significantly with pessimism but had no predictive value on dropout. Our results suggest that students with low levels of emotional clarity and repair and high depressive rumination have pessimistic expectations, so they are more likely to leave studies. No significant results were found in relation to academic performance. We conclude with an identification of strategies to increase retention and academic success.

  17. Reporting doping in sport: national level athletes' perceptions of their role in doping prevention.

    Science.gov (United States)

    Whitaker, L; Backhouse, S H; Long, J

    2014-12-01

    This paper qualitatively explores national level athletes' willingness to report doping in sport. Following ethical approval, semi-structured interviews were conducted with nine national level athletes from rugby league (n = 5) and track and field athletics (n = 4). Thematic analysis established the main themes within the data. Contextual differences existed around the role that athletes perceived they would play if they became aware of doping. Specifically, track and field athletes would adopt the role of a whistle-blower and report individuals who were doping in their sport. In comparison, the rugby league players highlighted a moral dilemma. Despite disagreeing with their teammates' actions, the players would adhere to a code of silence and refrain from reporting doping. Taking these findings into account, prevention programs might focus on changing broader group and community norms around doping. In doing so, community members' receptivity to prevention messages may increase. Moreover, developing skills to intervene (e.g., speaking out against social norms that support doping behavior) or increasing awareness of reporting lines could enhance community responsibility for doping prevention. In sum, the findings highlight the need to consider the context of sport and emphasize that a one-size-fits-all approach to anti-doping is problematic.

    2013-01-01

    Among potential predictors of dropout, client variables are most thoroughly examined. This qualitative literature review examines the current state of knowledge about therapist, relationship and process factors influencing dropout. Databases searches identified 44 relevant studies published January 2000-June 2011. Dropout rates varied widely with a weighted rate of 35%. Fewer than half of the studies directly addressed questions of dropout rates in relation to therapist, relationship or process factors. Therapists' experience, training and skills, together with providing concrete support and being emotionally supportive, had an impact on dropout rates. Furthermore, the quality of therapeutic alliance, client dissatisfaction and pre-therapy preparation influenced dropout. To reduce dropout rates, therapists need enhanced skills in building and repairing the therapeutic relationship.

    2010-12-01

    Drop-out of rehabilitation treatment in non-native patients with chronic low back pain has been reported to be higher than in native Dutch patients. It was expected that drop-out in non-native patients would be due to different expectations on the content of rehabilitation treatment and due to language or communication problems. Aim of this study was to determine differences in reasons for drop-out between native patients and non-native patients with chronic non-specific low back pain participating in a rehabilitation program. A retrospective study in medical files (N.=99) of patients who dropped out of treatment was performed in two rehabilitation centers and two rehabilitation departments of general hospitals. Patient files were checked for diagnosis, status of origin, gender, age and reason for drop-out. The differences in frequency in reasons for drop-out between native and non-native patients were tested by Chi-square tests. Withdrawal due to different expectations on the content of rehabilitation treatment occurred significantly more frequently in non-native patients (P=0.035). Withdrawal due to refusal to participate (no further reason given) occurred more often (P=0.008) in native Dutch patients than in non-native patients. No significant differences between non-native patients and native Dutch patients were reported regarding withdrawal due to language or communication problems, and no show (patient did not show up at consultation sessions without informing about the reason and without making an appointment for a new consultation). The present study provided evidence that drop-out in non-native patients is often related to different expectations regarding the content of rehabilitation treatment.

    Local television news is America's primary source of information and may be an opportunity to shape public opinion surrounding issues such as injury prevention. This study sought to systematically evaluate unintentional-injury coverage on local television news and to identify frequently interviewed public-service professionals and factors associated with discussion of risk factors and prevention. Late news broadcasts from 122 local television stations within the U.S. during October 2002 were analyzed. The main outcomes variables were counts of case-injury stories: motor-vehicle crashes, fires, falls, drowning, poisonings, and sports-recreational injuries; identification of interviewed public service professionals; and discussion of risk factors and prevention. Bivariate and mulitvariate analysis was performed to identify predictors of discussion of prevention measures, risk factors, or both. Data were analyzed in Fall 2006. From 2795 broadcasts, 1748 case-injury stories were identified. Fires and motor-vehicle crashes constituted 84% of the case-injury stories. There were 245 case-injury stories containing an interview with a public service professional. Police officers and firefighters accounted for 82% of these interviews. Interviews with police officers and firefighters were independently associated with discussion of risk factors and prevention measures for motor-vehicle crashes (OR=2.49, CI=1.7-3.6) and fires (OR=2.77, CI=1.2-5.9), respectively. Motor-vehicle crashes and fires were the most commonly reported injury topics. Police officers and firefighters were most commonly interviewed and, if interviewed, increased the likelihood that risk factors, prevention measures, or both were discussed. Optimizing the messages delivered by public service professionals through public service professional-level and media-level interventions may be an opportunity for disseminating injury-prevention information to the public and to policymakers, and methods to increase the

    Large volume paracentesis may cause paracentesis induced circulatory dysfunction (PICD). Albumin is recommended to prevent this abnormality. Meanwhile, the price of albumin is too expensive and there should be another alternative that may prevent PICD. This report aimed to compare albumin to colloids in preventing PICD. Search strategy was done using PubMed, Scopus, Proquest, dan Academic Health Complete from EBSCO with keywords of "ascites", "albumin", "colloid", "dextran", "hydroxyethyl starch", "gelatin", and "paracentesis induced circulatory dysfunction". Articles was limited to randomized clinical trial and meta-analysis with clinical question of "In hepatic cirrhotic patient undergone large volume paracentesis, whether colloids were similar to albumin to prevent PICD". We found one meta-analysis and four randomized clinical trials (RCT). A meta analysis showed that albumin was still superior of which odds ratio 0.34 (0.23-0.51). Three RCTs showed the same results and one RCT showed albumin was not superior than colloids. We conclude that colloids could not constitute albumin to prevent PICD, but colloids still have a role in patient who undergone paracentesis less than five liters.

    According to the 2014 Surgeon General's Report, smoking in early pregnancy can cause orofacial clefts. We sought to examine the implications of this causal link for the potential prevention of orofacial clefts in the United States. Using published data on the strength of the association between orofacial clefts and smoking in early pregnancy and the prevalence of smoking at the start of pregnancy, we estimated the attributable fraction for smoking as a cause of orofacial clefts. We then used the prevalence of orofacial clefts in the United States to estimate the number of orofacial clefts that could be prevented in the United States each year by eliminating exposure to smoking during early pregnancy. We also estimated the financial impact of preventing orofacial clefts caused by maternal smoking based on a published estimate of attributable healthcare costs through age 10 for orofacial clefts. The estimated attributable fraction of orofacial clefts caused by smoking in early pregnancy was 6.1% (95% uncertainty interval 4.4%, 7.7%). Complete elimination of smoking in early pregnancy could prevent orofacial clefts in approximately 430 infants per year in the United States, and could save an estimated $40.4 million in discounted healthcare costs through age 10 for each birth cohort. Understanding the magnitude of the preventable burden of orofacial clefts related to maternal smoking could help focus smoking cessation efforts on women who might become pregnant. © 2014 Wiley Periodicals, Inc.

    2013-04-01

    Little is known about the extent to which evidence-based prevention topics are taught in medical school. All class of 2003 medical students (n = 2316) at 16 US schools were eligible to complete three questionnaires: at the beginning of first and third years and in their senior year, with 80.3% responding. We queried these students about 21 preventive medicine topics, concerning the extent of their training and their patient counseling frequency at some of these time points. At the beginning of the third year, self-reported extensive training was low for all preventive medicine topics (range 7-26%). USPSTF-recommended topics received more curricular time (median for topics: 36% if recommended versus 24.5% if not, P = 0.025), as did topics addressed through testing rather than through discussion (median for topics: 37% for testing and 25% for discussion, P = 0.005). Extensive training was always associated with higher counseling frequency, and intention to go into primary care, female gender, a positive attitude toward prevention and positive personal health habits were associated with higher counseling frequency. Although some bemoan the overall low levels of US medical students' prevention-related training and practice, we demonstrate that at least they are preferentially evidence-based, a novel and encouraging finding for preventionists.

    Full Text Available Abstract This case report describes two cases of peri-prosthetic fracture during physical therapy in patients who underwent a hip resurfacing, or surface replacement arthroplasty. The fractures occurred with forceful passive combined flexion and external rotation. Functional results were ultimately obtained in both cases, requiring conversion to total hip arthroplasty. Recognizing patient risk factors and cautioning therapists about the possibility of fracture may have prevented these complications.

    We previously developed a molecular beacon-type probe to detect the strand scission in cellular base excision repair and found that the phosphodiester linkages in the fluorophore/quencher linkers were cleaved. This reaction was applied to a transfection reporter, which contained the unmodified phosphodiester in the linker to another type of fluorophore. After cotransfection of cells with the probe and the reporter, the signals were used to detect the incision and to confirm the proper transfection, respectively. This method will contribute to the prevention of false-negative results in experiments using molecular beacon-type probes. Copyright © 2013 Elsevier Inc. All rights reserved.

    In patients with asthma, particularly severe asthma, poor adherence to inhaled drugs negatively affects the achievement of disease control. A better adherence rate is expected in the case of injected drugs, such as omalizumab, as they are administered only in a hospital setting. However, adherence to omalizumab has never been systematically investigated. The aim of this study was to review the omalizumab drop-out rate in randomized controlled trials (RCTs) and real-life studies. A comparative analysis was performed between published data and the Italian North East Omalizumab Network (NEONet) database. In RCTs the drop-out rate ranged from 7.1 to 19.4 %. Although the reasons for withdrawal were only occasionally reported, patient decision and adverse events were the most frequently reported causes. In real-life studies the drop-out rate ranged from 0 to 45.5 %. In most cases lack of efficacy was responsible for treatment discontinuation. According to NEONet data, 32 % of treated patients dropped out, with an increasing number of drop outs observed over time. Patient decision and lack of efficacy accounted for most treatment withdrawals. Treatment adherence is particularly crucial in patients with severe asthma considering the clinical impact of the disease and the cost of non-adherence. The risk of treatment discontinuation has to be carefully considered both in the experimental and real-life settings. Increased knowledge regarding the main reasons for patient withdrawal is important to improve adherence in clinical practice.

  8. Review of Best Practices for CLABSI Prevention and the Impact of Recent Legislation on CLABSI Reporting

    2016-11-01

    Full Text Available Central line-associated bloodstream infections (CLABSI are a very common source of healthcare-associated infection (HAI. Incidence of CLABSI has been significantly reduced through the efforts of nurses, healthcare providers, and infection preventionists. Extrinsic factors such as recently enacted legislation and mandatory reporting have not been closely examined in relation to changes in rates of HAI. The following review will examine evidence-based practices related to CLABSI and how they are reported, as well as how the Affordable Care Act, mandatory reporting, and pay-for-performance programs have affected these best practices related to CLABSI prevention. There is a disconnect in the methods and guidelines for reporting CLABSI between these programs, specifically among local monitoring agencies and the various federal oversight organizations. Future research will focus on addressing the gap in what defines a CLABSI and whether or not these programs to incentivize hospital to reduce CLABSI rates are effective.

    There is concern over persons who fail to attend family planning clinics without reason. The represents 1 of the major stumbling blocks to a successful family planning program. The author investigated factors associated with clinic dropout among black women in a metropolitan area (Capetown, South Africa). Almost 1/2 of those who ceased to attend had a good reason for doing so. The main findings regarding the other defaulters included a lack of motivation among black women to prevent uplanned pregnancies through temporary contraception and that the program may not have met all of the public needs. In this regard, specific reference is made to the need of those women who no longer bring their youngest child to the child health clinic as family planning services are usually integrated into such a clinic.

    1991-10-01

    Coal fueled diesel engines present unique wear problems in the piston ring/cylinder liner area because of their tendency to contaminate the lube-oil with high concentrations of highly abrasive particles. This program involved a series of bench-scale wear tests and engine tests designed to investigate various aspects of the ring/liner wear problem and to make specific recommendations to engine manufacturers as to how to alleviate these problems. The program was organized into tasks, designed to accomplish the following objectives: (1) define the predominant wear mechanisms causing accelerated wear in the ring/liner area; (2) investigate the effectiveness of traditional approaches to wear prevention to prevent wear in coal-fueled engines; (3) further refine information on the most promising approaches to wear prevention; (4) present detailed information and recommendations to engine manufacturers on the most promising approach to wear prevention; (5) present a final report covering the entire program; (6)complete engine tests with a coal-derived liquid fuel, and investigate the effects of the fuel on engine wear and emissions.

  11. Newspaper media reporting of motor vehicle crashes in Singapore: an opportunity lost for injury prevention education?

    Heng, Kenneth W J; Vasu, Alicia

    2010-06-01

    Newspaper media advocacy can help steer public attention away from motor vehicle crash (MVC) injuries as a personal problem to that of a social and public health issue. If used properly, newspaper media is potentially a powerful mass educator on MVC prevention. However, there is often a conflict of interest in which newspapers, in an attempt to boost readership and revenue, may over-emphasize and sensationalize the human-interest aspect of an MVC story. The aim of this study is to examine newspaper articles of MVCs in Singapore to assess how our newspaper media coverage portray MVCs and identify factors that mitigate injury and educate the public on injury prevention measures. Details of the MVC were extracted from 12 months of newspaper coverage in Singapore. Two independent coders were used to establish inter-rater reliability. From 1 January to 31 December 2007, 201 articles about MVCs were published. About 74.1% of articles assigned blame to a particular road user, negligence on either road user was implied in 56.7% of articles, and road safety messages were mentioned in 8% of the articles. The mainstream communication tone used was positive for law enforcement (71.1%) and neutral towards injury prevention or road safety messages (89.1%). Newspaper media reporting of MVCs in Singapore generally does not include injury prevention messages or highlight injury-mitigating measures. This is a lost opportunity for public education. Collaboration between public health practitioners and newspaper media is required to address this issue.

    Cumulative IVF pregnancy rates are compromised by the large number of couples who drop-out of treatment before achieving pregnancy. The aim of this study was to identify the role of the treatment strategy applied, and potential other factors that influence the decision of couples to discontinue treatment. The incidence of drop-out from IVF treatment and factors related to drop-out were studied in a cohort of IVF patients aged dropped out of IVF treatment. The physical or psychological burden of treatment was the most frequent cause of drop-out (28%). The application of a mild treatment strategy (mild ovarian stimulation along with the transfer of a single embryo) significantly reduced the chance of drop-out (hazard ratio (HR) 0.55; 95% confidence interval (CI), 0.31-0.96). When a mild IVF strategy was employed, the association between the baseline anxiety score and drop-out was reduced by >50%. The presence of severe male subfertility (HR 4.80; 95% CI, 1.63-14.13) and the failure to achieve embryo transfer (odds ratio 0.41; 95% CI, 0.24-0.72) were also related to drop-out. Reducing drop-out rate is crucial to further improve the efficacy and cost-effectiveness of IVF treatment. An important factor determining the risk of drop-out is the burden of the treatment strategy. The application of a mild treatment strategy and managing patient's expectations might reduce drop-out rates.

    The Eighth Annual Frontiers in Cancer Prevention Research meeting was held in Houston, Texas, in November 2009. This report highlights significant presentations that advance the fields of chemoprevention, clinical trial recruitment and retention, cancer screening including optical imaging, energy balance, and nutritional epidemiology, and health communications and decision making. In findings from the randomized Reduction by Dutasteride of Prostate Cancer Events trial, dutasteride reduced the risk of biopsy-detectable prostate cancer in high-risk men by 23% compared with placebo. Important clues about the dosing and window of susceptibility for supplementation with choline, vitamin D, and folate were revealed from epigenetic research that has implications for future nutritional epidemiology research. Noninvasive optical imaging techniques using endoscopic ultrasound and autofluorescence for the early detection of cancers in the lung, pancreas, and oral cavity are being studied. The report also addresses the challenges of promoting cancer prevention. Understanding how individuals process risk information and make sustained behavior changes and the effect of socioeconomic status on health disparities were identified as critical areas of research.

    Background The Hong Kong news media report suicide-related events more frequently and sensationally than Western countries. Little is known about Hong Kong media professionals’ experiences and thoughts about such reporting. Aims To understand Hong Kong media professionals’ experiences and perceptions of suicide reporting and whether the news media can be better engaged into suicide prevention. Method We conducted three focus groups of journalists from both the Cantonese and English language news media. Data were analyzed using grounded theory methods. Results We discerned three rationales from participants regarding their intense coverage of suicide-related events: (1) satisfying commercial competitiveness, (2) addressing social problems, and (3) responding to readers’ interests. The first rationale was a dominant and vigorous motivating factor, and often influenced suicide reporting among local Cantonese media. Media professionals recommended engagement strategies targeted at frontline journalists, media managers, and general media consumers. Conclusion We see potential to involve news media professionals in Hong Kong as working partners in suicide prevention. To succeed, this effort requires engagement in a proactive, consistent, and sustained fashion. PMID:24322824

    Full Text Available Gender stereotypes are accepted preconceptions of what should be a man and a woman. Affect all areas of life, in the relationships that stablished in the family and the school. Within education, these stereotypes are reflected in the access, retention and completion of education degrees, as well as the area of study that preferred the women and men. They also have different effects on the causes of dropout depending on the gender to which they belong. This article aims to show the influence of gender stereotypes on dropout students and high school students in rural areas, specifically in three schools located in the municipality of El Fuerte, Sinaloa, the academic unit (AU San Blas and its extensions La Constancia and Las Higueras of Los Natoches. The results were obtained through a wider investigation in 2013.

    2014-01-01

    goal of this paper is to answer the following ques-tions:What is the dropout rate in the Open and distance education? What is the temporal regularity of dropout? What are the reasons for dropout? What types of students tend to dropout? How to prevent dropout and increase retention rate? The results show that dropout rates vary among study levels and majors, that the highest dropout rate appears in the first year, and that learners' gender and age, the location of learning center, learners' study level, major, and academic records influence dropout. This paper develops the Open and Distance Education Dropout Explanation Frame and Relationship Diagram of Essential Factors for Learners' Achievement to explore dropout occurrence mechanism and identify key elements that impact learners' completion of education. The paper also finds that learners tend to drop out for the following reasons:they are weak in distance education learning skills ( information literacy, time management ability, and teacher-student interaction);they chose a wrong major or an inappropriate study level;they are overloa-ded;they failed quite a number of courses;they are short of motivation;they are weak in will and determination for success;or they have economy problems. The paper contributes the research on open and distance education by propo-sing a retention rate formula, offering suggestions for going back to school, and exploring the impact of open and dis-tance education teaching system on dropout occurrence. In addition, the paper conducts cross-nation study on open and distance education dropout by comparing related research carried out in China and in U. K. .

  1. Academic dropout or academic success: a model for prediction.

    Kegel-Flom, P

    1986-09-01

    Why do some students who qualify for admission to optometry school become academic dropouts while others succeed? This question was addressed in a study which compared the admission records of 21 academic dropouts from three classes at the University of Houston College of Optometry (UHCO) with 269 retained students. Academic dropouts were found to have significantly lower preoptometry grades, lower Optometry College Admission Test (OCAT) scores, attended less competitive (i.e., less selective) undergraduate institutions, scored lower on the California Psychological Inventory (CPI), and were older than retained students. When these differentiating admission variables, excepting age, were applied to a new entering class, prediction of subsequent academic dismissal or serious academic difficulty was highly accurate. However, it was found that such prediction must take into account not only areas of weakness, i.e., academic and psychological factors which place a student at risk, but also areas of strength which give the student an advantage. For all students, regardless of age, sex, or ethnic origin, it was the ratio of "advantage" factors to "risk" factors which gave the most valid prediction of academic success or failure.

  2. Full report: Assessment and opportunity identification of energy efficient pollution prevention technologies and processes

    Energy Technology Data Exchange (ETDEWEB)

    1994-11-01

    US industry produces about 12 billion tons of waste a year, or two-thirds of the waste generated in the US. The costs of handling and disposing of these wastes are significant, estimated to be between $25 and $43 billion in 1991, and represent an increase of 66% since 1986. US industry also uses about one-third of all energy consumed in the nation, which adds to the environmental burden. Industrial wastes affect the environmental well-being of the nation and, because of their growing costs, the competitive abilities of US industry. As part of a national effort to reduce industrial wastes, the US Congress passed the Energy Policy Act (EPAct, P.L. 102-486). Section 2108, subsections (b) and (c), of EPAct requires the Department of Energy (DOE) to identify opportunities to demonstrate energy efficient pollution prevention technologies and processes; to assess their availability and the energy, environmental, and cost effects of such technologies; and to report the results. Work for this report clearly pointed to two things, that there is insufficient data on wastes and that there is great breadth and diversity in the US industrial sector. This report identifies: information currently available on industrial sector waste streams, opportunities for demonstration of energy efficient pollution prevention technologies in two industries that produce significant amounts of waste--chemicals and petroleum, characteristics of waste reducing and energy saving technologies identifiable in the public literature, and potential barriers to adoption of waste reducing technologies by industry.

    The aims of this study are (i) to assess the drop-out rate in an outpatient sample with mood disorder diagnosis in a psychotherapy unit; (ii) to focus clinical and sociodemographic variables related with drop-out; (iii) to delineate a psychopathological profile of the dropping-out patient through the SCL-90-R and OPD scores. The sample of this study includes 90 depressive patients, which came to our service for a psychotherapy. The outcome is classified as drop-out and non drop-out. Each patient is submitted to the multidimensional scale SCL-90-R in the course of the first interview. At the end of the first visit each patient has been evaluated through the first and the fourth OPD axis. A descriptive analysis of all the data collected was made and the principal links between clinical and sociodemographic variables and dropout, between SCL-90-R score and drop-out, and between OPD scores and drop-out were detected. About 42% of the patients were drop-out, of which 89% by the third session. The variables associated with drop-out are: pathological score in the paranoic and interpersonal sensibility scale of SCL-90-R, low compliance scores, low integration of defences, self perception, object's perception and link. The drop-out rate in depressive patients turned out to be frequent. The patient's resources in terms of relationship, self-perception and object's perception are strongly related to the drop-out risk. These results are suggestive for the idea that the evaluation of drop-out risk in psychiatric patients must considerate the subjective aspects of the patient besides the clinical features.

    Severe hypertriglyceridemia is a common indication for the need of plasma exchange in treatment of hypertriglyceridemic-induced pancreatitis when normal therapies fail to garner a response. Application of plasmapheresis to prevent complication of hypertriglyceridemia is limited because of its cost and availability. We present a case of a 44-year-old man with metabolic syndrome and a medical history of secondary polycythemia in obesity hypoventilation syndrome, whose laboratory tests revealed a triglycerides value of 3965 mg/dL. To prevent the complication of pancreatitis due to hypertriglyceridemia, we performed plasma exchange 3 times when conventional treatments did not sufficiently reduce the high level of triglycerides. A review of the current available literature was therefore conducted to provide an overview of the present data on apheretic treatment for patients with severe hypertriglyceridemia. Several case reports and case series have used plasmapheresis in acute treatment of hypertriglyceridemia pancreatitis related. In our case, the choice of plasmapheresis was applied in prevention of possible complications of hypertriglyceridemia.

    Full Text Available Crimean-Congo hemorrhagic fever (CCHF is endemic in Eurasian countries such as, Turkey, Pakistan, Afghanistan and Iran. CCHF virus is spread by the Hyalomma tick, which is found mainly on cattle and sheep. Muslim countries, in which these animals are sacrificed during Eid-Al-Adha, are among the countries where CCHF is endemic, and it has been observed that CCHF is associated with practices surrounding the Eid-ad-Adha festival. The dates for Eid-Al-Adha drift 10 days earlier in each year according to Georgian calendar. In previous years Eid-al-Adha occurred in autumn-winter months however in the next 10-15 years it will be take place in the summer months when CCHF is more prevalent. This may lead to a rise in the number of cases due to increased dissemination of CCHF virus with uncontrolled animal movements in and between countries. This consensus report focuses on the variable practices regarding animal handling in different regions and possible preventative measures to reduce the incidence of CCHF. Environmental hygiene and personal protection are essential parts of prevention. There is a need for international collaborative preparedness and response plans for prevention and management of CCHF during Eid-Al-Adha in countries where the disease is prevalent.

    We discuss the model for estimating drop-out probabilities presented by Tvedebrink et al. [7] and the concerns, that have been raised. The criticism of the model has demonstrated that the model is not perfect. However, the model is very useful for advanced forensic genetic work, where allelic drop-out is occurring. With this discussion, we hope to improve the drop-out model, so that it can be used for practical forensic genetics and stimulate further discussions. We discuss how to estimate drop-out probabilities when using a varying number of PCR cycles and other experimental conditions. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    2015-01-01

    Full Text Available Postoperative portomesenteric venous thrombosis (PMVT is being increasingly reported after bariatric surgery. It is variable and often a nonspecific presentation along with its potential for life-threatening and life-altering outcomes makes it imperative that it is prevented, detected early and treated optimally. We report the case of a 50-year-old morbidly obese man undergoing a laparoscopic sleeve gastrectomy who developed symptomatic PMVT two weeks postsurgery, which was successfully treated by anticoagulant therapy. We provide postulates to the etiopathological mechanism for this thrombotic entity. The growing recognition that obesity and bariatric surgery create a procoagulant state regionally and systemically provides impetus for designing the ideal protocol for PMVT prophylaxis, which could be more common than currently believed. We support the early screening for PMVT in the postbariatric surgical patient with unexplainable or intractable abdominal symptoms. The role of routine surveillance and the ideal duration of post-PMVT anticoagulation is yet to be elucidated.

    An important goal of the US DOE reactor development program is to conceptualize advanced safety design features for a demonstration Sodium Fast Reactor (SFR). The treatment of severe accidents is one of the key safety issues in the design approach for advanced SFR systems. It is necessary to develop an in-depth understanding of the risk of severe accidents for the SFR so that appropriate risk management measures can be implemented early in the design process. This report presents the results of a review of the SFR features and phenomena that directly influence the sequence of events during a postulated severe accident. The report identifies the safety features used or proposed for various SFR designs in the US and worldwide for the prevention and/or mitigation of Core Disruptive Accidents (CDA). The report provides an overview of the current SFR safety approaches and the role of severe accidents. Mutual understanding of these design features and safety approaches is necessary for future collaborations between the US and its international partners as part of the GEN IV program. The report also reviews the basis for an integrated safety approach to severe accidents for the SFR that reflects the safety design knowledge gained in the US during the Advanced Liquid Metal Reactor (ALMR) and Integral Fast Reactor (IFR) programs. This approach relies on inherent reactor and plant safety performance characteristics to provide additional safety margins. The goal of this approach is to prevent development of severe accident conditions, even in the event of initiators with safety system failures previously recognized to lead directly to reactor damage.

    Treatment adherence in patients with eating disorders (ED) in Iceland is unknown. The aim of the study was to investigate treatment drop-out and explore factors that influence premature termination of treatment in a specialized ED treatment unit, at the University Hospital of Iceland, during the period of September 1, 2008 - May 1, 2012. The study is retrospective and naturalistic. Hospital records of referred patients were examined. Those meeting the ICD 10 criteria of anorexia nervosa (AN) (F50.0, F50.1), bulimia nervosa (BN) (F50.2, F50.3) and eating disorder not otherwise specified (EDNOS) (F50.9) were included. The total sample was 260 and 182 patients met inclusion criteria. No-shows were 7%. Drop-out was defined as premature termination of treatment without formal discharge. The sample consisted of 176 women and 6 men, mean age 26.3 years. BN was diagnosed in 52.7% of patients, EDNOS in 36.8% AN in 10.4%. 74.7% had one or more co-morbid psychiatric diagnosis. Anxiety- and/or depression were diagnosed in 72.5%, Attention hyperactivity deficiency disorder in 15.4% and personality disorders in 8.2%. Lifetime prevalence of substance use disorders (SUDs) was 30.8%. Drop-out from treatment occurred in 54.4% of cases (with approximately 1/3 returning to treatment), 27.5% finished treatment and 18.1% were still in treatment at the end of the follow up period. Treatment adherence was significantly higher in patients who had a university degree, in those who had themselves taken the initiative to seek ED treatment and in those with higher anxiety scores at assessment. AN patients did better than other ED patients while patients with SUDs showed a tendency for higher drop-out (p=0.079). The drop-out rates were similar to what has been reported from other western countries. Follow-up time was longer and AN patient did better than expected. Higher education, initiative in seeking treatment and higher anxiety scores on questionnaires were protective.

    2014-02-01

    Full Text Available Introduction: Health services are composed of complex work environments. For this reason, they present several risks to the health of workers and also of people being treated at these places. Among these risks, one that is peculiar to health services is the risk of occupational accidents with biological material involving sharps. Objective: This study aimed to describe a health education activity conducted in a Health Center of the Federal District, Brazil. Methods: This is an experience report that discusses the final paper of the discipline “Administration Applied to Nursing and Internship”, offered by the Department of Nursing, Faculty of Health Sciences, University of Brasilia. A lecture was prepared, aimed at health workers and support staff, on general aspects of occupational accidents involving sharps, as well as preventive aspects. Results: In each clinical room of the Health Center were fixed two posters: the first discussing the proper disposal of sharps and the second, in turn, was a message of reflection. 31 professionals attended the lecture as listeners. Conclusion: We understand the validity of the lecture delivered, based on scientific studies that highlight the need and shortage of health education activities that address the prevention of occupational accidents involving sharps among Health Professionals. Additionally, it is important mentioning that such activity demand was estimated by the workers of the Health Center in study.

    This report was developed from experiences with three New Jersey firms and is intended to be a guide for conducting analyses on resource (energy and raw materials) utilization and pollution (solid waste, air and water emissions) prevention in plastics processing plants. The protocol is written on the assumption that the analysis is to be done by an outside agency such as a consulting firm, but it also can be used for internal audits by plant teams. Key concepts in this analysis were adapted from life cycle analysis. Because of the small sample of companies studied, the results have to be considered high preliminary, but some of the conclusions will probably be confirmed by further work.

    This Executive Summary of the Global Strategy for the Diagnosis, Management, and Prevention of COPD (GOLD) 2017 Report focuses primarily on the revised and novel parts of the document. The most significant changes include: i) the assessment of COPD has been refined to separate the spirometric assessment from symptom evaluation. ABCD groups are now proposed to be derived exclusively from patient symptoms and their history of exacerbations; ii) for each of the groups A to D, escalation strategies for pharmacological treatments are proposed; iii) the concept of de-escalation of therapy is introduced in the treatment assessment scheme; iv) nonpharmacologic therapies are comprehensively presented and; v) the importance of comorbid conditions in managing COPD is reviewed.

    In this case report we describe a 49 year-old man who presented with chronic urticaria, angioedema and soft stool consistency. During diagnostic examinations Hashimoto's thyroiditis was found even though the patient never had clear symptoms of this disease. Blastocystis hominis was isolated through a stool microbiologic examination, implicating that this parasite can cause the development of Hashimoto's thyroiditis and chronic urticaria. After two-weeks treatment with metronidazole the Blastocystis hominis was eradicated, then urticaria and angioedema disappeared. During the four years of follow-up, the patient presented without any symptoms, whereas thyroid hormones were normalized and anti-thyroid antibodies declined. For the first time in the literature we show that eradication of Blastocystis hominis can prevent the development of both symptomatic Hashimoto's thyroiditis and chronic urticaria.

    Full Text Available A 47-year-old African-American woman was admitted to the intensive care unit of our community hospital for respiratory failure secondary to severe decompensated heart failure, requiring intubation. In the ensuing days, she developed a methicillin-resistant Staphylococcus aureus (MRSA infection of the cornea, despite no growth of MRSA in multiple blood, sputum, and urine cultures. This unexpected corneal infection complicated her hospital stay, and increased morbidity and disease-related cost. Risk factors, warning signs, and preventative measures for MRSA keratitis secondary to lagophthalmos (inability to completely close one's eyelids are outlined in this case report. Implementing simple precautions such as taping eyelids shut or using artificial lubrication may reduce patient morbidity and disease-related costs. These recommendations are directed to non-ophthalmic clinicians who provide care to patients in settings where MRSA colonization is widespread.

    2009-10-01

    Full Text Available Abstract Background Dropout (DO is common in the treatment of eating disorders (EDs, but the reasons for this phenomenon remain unclear. This study is an extensive review of the literature regarding DO predictors in EDs. Methods All papers in PubMed, PsycINFO and Cochrane Library (1980-2009 were considered. Methodological issues and detailed results were analysed for each paper. After selection according to inclusion criteria, 26 studies were reviewed. Results The dropout rates ranged from 20.2% to 51% (inpatient and from 29% to 73% (outpatient. Predictors of dropout were inconsistent due to methodological flaws and limited sample sizes. There is no evidence that baseline ED clinical severity, psychiatric comorbidity or treatment issues affect dropout. The most consistent predictor is the binge-purging subtype of anorexia nervosa. Good evidence exists that two psychological traits (high maturity fear and impulsivity and two personality dimensions (low self-directedness, low cooperativeness are related to dropout. Conclusion Implications for clinical practice and areas for further research are discussed. Particularly, these results highlight the need for a shared definition of dropout in the treatment of eating disorders for both inpatient and outpatient settings. Moreover, the assessment of personality dimensions (impulse control, self-efficacy, maturity fear and others as liability factors for dropout seems an important issue for creating specific strategies to reduce the dropout phenomenon in eating disorders.

    2016-01-01

    Drop-out is a complex problem in mental health care and in STEPPS. Research has revealed a variety of predicting factors and has produced contradictory results. To investigate whether the information available at the start of STEPPS can pinpoint predictors of drop-out. The ROM data for 150 patients were used to test the link between the following factors: age, gender, education, employment, substance abuse, anxiety, hostility, interpersonal relations, responsibility and social concordance with drop-out. The method used for testing was logistic regression analysis. Factors that contributed significantly to the prediction of drop-out were gender and employment status. These factors made up 16% of the explained variation (R2 Nagelkerkes) in drop-out. Gender was the strongest predictive factor. Concerning the other factors, no differences were found between groups (drop-out and non-dropouts). In its present form STEPPS does not suit a large number of the male participants. Drop-out during STEPPS is hard to predict on the basis of ROM-questionnaires. Future research should focus on preconditions and marginal conditions that influence patients to complete their training.

    Klein-Radukic, Sarah; Zmyj, Norbert

    2015-11-01

    Dropout of infants in looking time studies sometimes occurs at high rates, raising concerns that the representativeness of the final sample might be reduced in comparison to the originally obtained sample. The current study investigated which infant characteristics play a role in dropout. Infants were presented with a preferential looking task at 6 and 9 months of age. At 9 months of age, an additional habituation task and a subsequent novelty preference task were conducted. In addition, temperament was assessed via the Infant Behavior Questionnaire - Revised (IBQ-R, Gartstein & Rothbart, 2003), and cognitive developmental status was assessed via the Cognitive Scale of the Bayley Scale of Infant and Toddler Development (BSID-III, Bayley, 2006). Dropout was positively related to the IBQ-R temperament scales Distress to Limitations and Approach, and negatively related to the scales Falling Reactivity and Cuddliness. The representativeness of the final sample regarding situation-specific temperament dimensions is affected by dropout. Dropout was not related to cognitive developmental status as measured via the BSID-III, habituation speed and novelty preference. Dropout at 6 months of age was associated with dropout at 9 months of age. We concluded that in looking time studies, the representativeness of the final sample regarding performance-relevant temperament dimensions or cognitive developmental status is not affected by dropout.

    A low voltage implementation of a CMOS Low Drop-Out voltage regulator (LDO) is presented. The requirement of low voltage devices is crucial for portable devices that require extensive computations in a low power environment. The LDO is implemented in 90nm generic CMOS technology. It generates a fixed 0.8V from a 2.5V supply which on discharging goes to 1V. The buffer stage used is unity gain configured unbuffered OpAmp with rail-to-rail swing input stage. The simulation result shows that the implemented circuit provides load regulation of 0.004%/mA and line regulation of -11.09mV/V. The LDO provides full load transient response with a settling time of 5.2μs. Further, the dropout voltage is 200mV and the quiescent current through the pass transistor (Iload=0) is 20μA. The total power consumption of this LDO (excluding bandgap reference) is only 80μW.

    In 2009, the Center for Strategic Analysis initiated a study, entitled Neurosciences and Public Policies, to assess the use of neurosciences in prevention policy. Subsequently, a report highlighted the inefficiency of the "traditional" prevention programs and the potential contribution of neurosciences to defining a new prevention approach. For the French National Federation for Health Education and Promotion, health promotion cannot be limited to a "counter-manipulation" of consumers confronted with marketing strategies from the food and tobacco industries.

    A flux dropout is a sudden and considerable decrease in the relativistic electron population of the outer radiation belt on the timescale of a few hours. The dropout is generally driven by loss to the atmosphere mainly due to EMIC waves or drift loss to the magnetopause. A significant dropout was observed from Van Allen Probes during the storm on June 1 2013. However, there did not appear that EMIC waves are strong enough to cause considerable precipitating loss of Multi-MeV electrons from both Van Allen Probes and ground-based observatory during this dropout. Moreover, Polar-orbiting Operational Environmental Satellite (POES) rarely detected precipitating flux of > 1 MeV. To understand physical mechanisms of this dropout, we used Comprehensive Inner Magnetosphere and Ionosphere (CIMI) model and simulated flux and phase space density of relativistic electrons without pitch-angle scattering due to EMIC waves. The CIMI simulation using Tsyganenko 2004 magnetic model reproduced the significant dropout. The minimum last closed drift shell calculated by CIMI model was estimated to be L* = 4.55 during this event. CIMI also showed a strong induced-electric field due to displacement of the magnetic field line at the magnetic equator even at L* < 4.55, which can result in outward radial transport of relativistic electrons. We conclude that outward radial transport due to strong induced-electric field and drift loss to the magnetopause are main causes of this dropout.

    Transfusions are the primary therapy for thalassemia but have significant cumulative risks. In 2004, the Centers for Disease Control and Prevention (CDC) established a national blood safety monitoring program for thalassemia. This report summarizes the population and their previous nonimmune and immune transfusion complications. The CDC Thalassemia Blood Safety Network is a consortium of centers longitudinally following patients. Enrollment occurred from 2004 through 2012. Demographics, transfusion history, infectious exposures, and transfusion and nontransfusion complications were summarized. Logistic regression analyses of factors associated with allo- and autoimmunization were employed. The race/ethnicity of these 407 thalassemia patients was predominantly Asian or Caucasian. The mean ± SD age was 22.3 ± 13.2 years and patients had received a mean ± SD total number of 149 ± 103.4 units of red blood cells (RBCs). Multiorgan dysfunction was common despite chelation. Twenty-four percent of transfused patients had previous exposure to possible transfusion-associated pathogens including one case of babesia. As 27% were immigrants, the infection source cannot be unequivocally linked to transfusion. Transfusion reactions occurred in 48%, including allergic, febrile, and hemolytic; 19% were alloimmunized. Common antigens were E, Kell, and C. Years of transfusion was the strongest predictor of alloimmunization. Autoantibodies occurred in 6.5% and were associated with alloimmunization (p thalassemia. New pathogens were noted. National guidelines for RBC phenotyping and preparation are needed to decrease transfusion-related morbidity. © 2013 American Association of Blood Banks.

This systematic review provides an overview of different control groups design characteristics of exercise-oncology trials and explores the association with contamination and drop-out rates. Randomized controlled exercise-oncology trials from two Cochrane reviews were included. Additionally, a computer-aided search using Medline (Pubmed), Embase and CINAHL was conducted after completion date of the Cochrane reviews. Eligible studies were classified according to three control group design characteristics: the exercise instruction given to controls before start of the study (exercise allowed or not); and the intervention the control group was offered during (any (e.g., education sessions or telephone contacts) or none) or after (any (e.g., cross-over or exercise instruction) or none) the intervention period. Contamination (yes or no) and excess drop-out rates (i.e., drop-out rate of the control group minus the drop-out rate exercise group) were described according to the three design characteristics of the control group and according to the combinations of these three characteristics; so we additionally made subgroups based on combinations of type and timing of instructions received. 40 exercise-oncology trials were included based on pre-specified eligibility criteria. The lowest contamination (7.1% of studies) and low drop-out rates (excess drop-out rate -4.7±9.2) were found in control groups offered an intervention after the intervention period. When control groups were offered an intervention both during and after the intervention period, contamination (0%) and excess drop-out rates (-10.0±12.8%) were even lower. Control groups receiving an intervention during and after the study intervention period have lower contamination and drop-out rates. The present findings can be

    Response to antidepressants is higher in active comparator relative to placebo-controlled clinical trials. Increased patient expectancy in comparator trials has been hypothesized to explain this finding, but previous analyses have not accounted for the increased drop-out observed in placebo-controlled trials. A systematic literature review was conducted to identify published antidepressant clinical trials reporting data on intent-to-treat (ITT) as well as completer patient populations. The influence of participant drop-out on observed antidepressant response was investigated by comparing the ITT and completer data sets in separate multilevel meta-analyses of antidepressant response in placebo-controlled and comparator trials. 18 placebo-controlled and 18 active comparator studies were available for analysis. Using the intent-to-treat data, the odds of responding to medication in comparator trials were 1.9 times the odds in placebo-controlled trials (95% CI=1.3-2.7, p=0.001). The same pattern was obtained among study completers, in whom the odds of responding to antidepressant medication were 1.9 times higher in comparator as opposed to placebo-controlled study designs (95% CI=1.2-3.0, p=0.009). Publication bias, the use of trial-level summary data, and unreported clinical or demographic differences between the ITT and completer patient populations may have influenced the study results. Increased drop-out in placebo-controlled vs. active comparator studies of antidepressant medications does not appear to explain the difference in response rates between these study types. Rather, increased patient expectancy resulting from the certainty of receiving active medication in comparator trials may lead to improved response rates. Copyright © 2012 Elsevier B.V.

    2013-01-01

    Full Text Available This paper investigates the dynamic output feedback control for nonlinear networked control systems with both random packet dropout and random delay. Random packet dropout and random delay are modeled as two independent random variables. An observer-based dynamic output feedback controller is designed based upon the Lyapunov theory. The quantitative relationship of the dropout rate, transition probability matrix, and nonlinear level is derived by solving a set of linear matrix inequalities. Finally, an example is presented to illustrate the effectiveness of the proposed method.

  2. An Imputation Model for Dropouts in Unemployment Data

    2016-09-01

    Full Text Available Incomplete unemployment data is a fundamental problem when evaluating labour market policies in several countries. Many unemployment spells end for unknown reasons; in the Swedish Public Employment Service’s register as many as 20 percent. This leads to an ambiguity regarding destination states (employment, unemployment, retired, etc.. According to complete combined administrative data, the employment rate among dropouts was close to 50 for the years 1992 to 2006, but from 2007 the employment rate has dropped to 40 or less. This article explores an imputation approach. We investigate imputation models estimated both on survey data from 2005/2006 and on complete combined administrative data from 2005/2006 and 2011/2012. The models are evaluated in terms of their ability to make correct predictions. The models have relatively high predictive power.

    2009-10-01

    This study aimed to identify treatment, therapist and patient factors associated with dropping out of treatment in four outpatient mental health services. The experimental group comprised all 789 individuals who attended for the first time the mental health services during one year and dropped out of treatment in the same year or during the two following ones. The control group consisted of the same number of individuals, chosen at random from patients who, in the same year, attended for the first time the services and did not subsequently drop out of treatment. The overall drop-out rate was 33.2%. According to logistic regression analysis, the predictive factors of dropping out were: being treated in a particular centre, the involvement of more than one therapist in treatment, having no previous history of psychiatric disorders, being young and being male.

    Background and Study Objectives Transfusions are the primary therapy for thalassemia but have significant cumulative risks. In 2004, the Centers for Disease Control and Prevention (CDC) established a national blood safety monitoring program for thalassemia. The purpose of this report is to summarize the patient population as well as previous non-immune and immune transfusion complications at the time of enrollment into the program. A focus on factors associated with allo- and auto-immunization in chronically transfused patients and a description of blood product preparation and transfusion practices at the participating institutions are included. Study Design and Methods The CDC Thalassemia Blood Safety Network is a consortium of thalassemia centers, longitudinally following patients to determine transfusion-related complications. Enrollment occurred from 2004 through 2012 and annual data collection is ongoing. Demographic data, transfusion history, and previous transfusion and non-transfusion complications were summarized for patients enrolled between 2004 and 2011. Logistic analyses of factors associated with allo- and auto-immunization were developed. Summary statistics of infections reported at the time of enrollment were also calculated. Results The race/ethnicity of the 407 thalassemia patients enrolled in the Network was predominantly Asian or Caucasian and 27% were immigrants. The average age was 22.3 years ± 13.2 and patients received an average total number of 149 ± 103.4 units of red blood cells. Iron-induced multi-organ dysfunction was common despite chelation. At study entry, 86 patients had previously been exposed to possible transfusion-associated pathogens, including Hepatitis-C (61), Hepatitis B (20), Hepatitis A (3), Parvovirus (9), HIV (4), malaria (1), staphylococcus aureus (1) and babesia (1). As 27% of the population was born outside of the United States (India, Pakistan, Thailand, China, Vietnam and Iran accounting for 57%), the source of

    Oral, breast, and cervical cancers are amenable to early detection and account for a third of India's cancer burden. We convened a symposium of diverse stakeholders to identify gaps in evidence, policy, and advocacy for the primary and secondary prevention of these cancers and recommendations to accelerate these efforts. Indian and global experts from government, academia, private sector (health care, media), donor organizations, and civil society (including cancer survivors and patient advocates) presented and discussed challenges and solutions related to strategic communication and implementation of prevention, early detection, and treatment linkages. Innovative approaches to implementing and scaling up primary and secondary prevention were discussed using examples from India and elsewhere in the world. Participants also reflected on existing global guidelines and national cancer prevention policies and experiences. Symposium participants proposed implementation-focused research, advocacy, and policy/program priorities to strengthen primary and secondary prevention efforts in India to address the burden of oral, breast, and cervical cancers and improve survival.

    Full Text Available Objective: To evaluate effects of a preventive monitoring program targeted to reduce compulsory re-hospitalization and perceived coercion in patients with severe mental disorder. We analyze patient outcomes in terms of perceived coercion, empowerment and self-reported mental health functioning at 12 months. Methods: The program consists of individualized psycho-education, crisis cards and, after discharge from the psychiatric hospital, a 24-month preventive monitoring. In total, 238 psychiatric inpatients who had had compulsory admission(s during the past 24 months were included in the trial. T1-assessment 12 months after baseline was achieved for 182 patients. Results: Study participants reported lower levels of perceived coercion, negative pressures and process exclusion, a higher level of optimism, and a lesser degree of distress due to symptoms, interpersonal relations and social role functioning (significant time effects. However, improvements were not confined to the intervention group, but seen also in the TAU group (no significant group or interaction effects. Altered perceptions were linked to older age, shorter illness duration, female sex, non-psychotic disorder, and compulsory hospitalization not due to risk of harm to others. Conclusion: Our findings suggest that changes in the subjective perspective were fuelled primarily by participation in this study, rather than by having received the specific intervention. The study contributes to a better understanding of the interaction between 'objective' measures (compulsory readmissions and patients’ perceptions and highlights the need for treatment approaches promoting empowerment in individuals with a history of involuntary psychiatric hospitalizations.

    Silent or subclinical celiac disease may result in potentially avoidable adverse health consequences. To review the evidence on benefits and harms of screening for celiac disease in asymptomatic adults, adolescents, and children 3 years and older for the US Preventive Services Task Force. Ovid MEDLINE, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systematic Reviews, searched to June 14, 2016. Randomized clinical trials and cohort or case-control studies on clinical benefits and harms of screening vs no screening for celiac disease or treatment vs no treatment for screen-detected celiac disease; studies on diagnostic accuracy of serologic tests for celiac disease. One investigator abstracted data, a second checked data for accuracy, and 2 investigators independently assessed study quality using predefined criteria. Cancer incidence, gastrointestinal outcomes, psychological outcomes, child growth outcomes, health outcomes resulting from nutritional deficiencies, quality of life, mortality, and harms of screening. No meta-analytic pooling was done. One systematic review and 3 primary studies met inclusion criteria. No trials of screening for celiac disease were identified. One recent, good-quality systematic review of 56 original studies and 12 previous systematic reviews (sample sizes of primary studies ranging from 62 to more than 12 000 participants) found IgA tissue transglutaminase was associated with high accuracy (sensitivity and specificity both >90%) for diagnosing celiac disease. IgA endomysial antibodies tests were associated with high specificity. Only 2 studies of serologic tests for celiac disease involving 62 and 158 patients were conducted in asymptomatic populations and reported lower sensitivity (57% and 71%). One fair-quality, small (n = 40) Finnish treatment trial of asymptomatic adults with screen-detected celiac disease based on positive serologic findings found initiation of a gluten-free diet associated with

    Cerebrovascular disease (CVD) is the main killer in the modern society and the most frequent cause of death and disability. According to the experiences of highly developed Western countries, especially of the U.S.A., the incidence of stroke can be reduced by the development and introduction of preventive actions and change of life style. Incidence of cerebrovascular disease is high in Croatia as well as in Spain (46% in the 46-59 age range) with an increasing tendency in younger population. As prevention is the only way of CVD incidence reduction, it is indispensable to organize an integral preventive neurologic network. Within the W.H.O. project "Health for All by the Year 2000 and the project "Zagreb"--Healthy City" a preventive action under the slogan 'With perfect brain and veins--enjoy the healthy days', has been organized with the aim to reduce the incidence of stroke for 20% during the following 10-year period. A standardized work of preventive network in Zagreb has also been established in Barcelona as a joint work. Using the interdisciplinary counselling approach, medical teams are still making examinations. In Zagreb Center for Neurological Sciences and Brain Research, data of risk factor distributions and trends of stroke incidence changes have been collected and the results have been analyzed. The Zagreb Center has also become a center for continuous evaluation and further planning. In this article functions of preventive centers, the preventive standardized protocol and structural and functional preventive network are introduced. The results of preventive action in Zagreb are also briefly presented.

    A substantial minority of people drop out of cognitive-behavioral therapies (CBTs) for posttraumatic stress disorder (PTSD). There has been considerable research investigating who drops out of PTSD treatment; however, the question of when dropout occurs has received far less attention. The purpose of the current study was to examine when individuals drop out of CBT for PTSD. Women participants (N = 321) were randomized to 1 of several PTSD treatment conditions. The conditions included prolonged exposure (PE), cognitive processing therapy (CPT), CPT-cognitive only (CPT-C), and written accounts (WA). Survival analysis was used to examine temporal pattern of treatment dropout. Thirty-nine percent of participants dropped out of treatment, and those who dropped out tended to do so by midtreatment. Moreover, the pattern of treatment dropout was consistent across CBT conditions. Additional research is needed to examine if treatment dropout patterns are consistent across treatment modalities and settings.

    2013-01-01

    This study investigated psychotherapy dropout rates and predictors of dropping out of therapy early. We enrolled 1,166 men voluntarily admitted to psychotherapy for violent behavior against a female partner. In total, 315 (23.8%) subjects dropped out of therapy within the first 3 sessions. Dropouts were significantly younger, more likely to have a non-Norwegian ethnic background, less likely to have received previous mental health care, and were more likely to have been treated by a student therapist. Among those treated by a student therapist, unemployment was strongly associated with early dropout. Unadjusted and adjusted results were similar. Clients and therapists may benefit by matching unemployed men with experienced therapists. Finally, the high dropout rates among ethnically non-Norwegian clients points to a need for special treatment approaches for this subgroup.

    SUMMARY During the study period of three months, out of 425 patients attending the psychiatric clinic of a general hospital, for the first time, 165 (38.8%) did not complete the treatment as prescribed by the doctors and were considered as dropouts. They were contacted at their homes to find out the reasons of the dropping out, were compared with patients, who completed the treatment fully on socio-demographic variables and attitude towards treatment. Dropouts significantly differed from treatment acceptors regarding their income, place of domicile and occupation. Maximum number of patients (59.9%) dropped out after the first visit. Dropouts were the maximum among epileptics, and minimum among the mentally retarded patients. Dropouts were dissatisfied with their experience at the clinic as treatment advised was not of their choice, and they feared bad side effects from ECT and drugs. Long distance of residence from clinic was an important reason for dropping out, besides social and economic reasons. PMID:21927444

  19. Bayesian informative dropout model for longitudinal binary data with random effects using conditional and joint modeling approaches.

    Science.gov (United States)

    Chan, Jennifer S K

    2016-05-01

    Dropouts are common in longitudinal study. If the dropout probability depends on the missing observations at or after dropout, this type of dropout is called informative (or nonignorable) dropout (ID). Failure to accommodate such dropout mechanism into the model will bias the parameter estimates. We propose a conditional autoregressive model for longitudinal binary data with an ID model such that the probabilities of positive outcomes as well as the drop-out indicator in each occasion are logit linear in some covariates and outcomes. This model adopting a marginal model for outcomes and a conditional model for dropouts is called a selection model. To allow for the heterogeneity and clustering effects, the outcome model is extended to incorporate mixture and random effects. Lastly, the model is further extended to a novel model that models the outcome and dropout jointly such that their dependency is formulated through an odds ratio function. Parameters are estimated by a Bayesian approach implemented using the user-friendly Bayesian software WinBUGS. A methadone clinic dataset is analyzed to illustrate the proposed models. Result shows that the treatment time effect is still significant but weaker after allowing for an ID process in the data. Finally the effect of drop-out on parameter estimates is evaluated through simulation studies.

Networked Control System (NCS is described as a time-delay switched system with constrained switching signals. A switched dynamic output feedback controller with prescribed disturbance attenuation level is designed via a cone complement linearization approach. A novel stability criterion is obtained by switched system theory. Furthermore, finding an appropriate quantization density used when packet dropout occurs is converted to an optimization problem.

    This study aims to identify the reasons why enrolled people decide not to renew their membership in following years. Household survey is used to collect information on the factors influencing dropping out from community-based health insurance (CBI). Information from CBI agency databank is used to describe the general situation of enrolment and drop-out. Since the launch of CBI the enrolment rate has been low ranging from 5.2% to 6.3%. The drop-out rate, however, has been high ranging from 30.9% to 45.7%. It is found, by the multivariate analysis, that female household head, higher age or lower education of a household head, lower number of illness episodes in the past three months, fewer children or elderly in a household, poor perceived health care quality, less seeking care in the past month positively effected on drop-out, increasing the rate. However, the household six-month expenditure and the distance to the contracted health facility did not have the hypothesised sign. In contrast, a higher household expenditure and a shorter distance to the contracted health facility increased the drop-out. High drop-out rates endanger the sustainability of CBI not only because they reduce the size of the insurance pool, but also because they bear a negative impact on further enrolment and drop-out. The drop-out rate in the scheme of the Nouna Health District, Burkina Faso, is very high. The reasons for drop-out may be related to affordability, health-needs and health demand, quality of care, household head and household characteristics. This study represents a valuable attempt towards further increasing the sustainability of CBI schemes, by understanding not what motivates people to first enrol in CBI, but what motivates them to renew membership year after year.

  4. Rethinking Dropout in Online Higher Education: The Case of the Universitat Oberta de Catalunya

    Directory of Open Access Journals (Sweden)

    Josep Grau-Valldosera

    2014-02-01

    Full Text Available In recent years, several studies have been carried out into the reasons why students drop out of online higher education, following the rise in the relative weight of this form of education. However, more effort has gone into analyzing the causes of this phenomenon than into trying to characterize students who drop out, that is defining what a dropout student is. But obtaining a proper definition of dropout is just as important as describing its causes. It also appears that the definition of dropout is very sensitive to context. As one of the main findings of this article, we reach a pure empirical definition, at a programme level, of students who drop out of an online higher education context with non-mandatory enrollment. This definition is based on the probability of students not continuing a specific academic programme following several consecutive semesters of “theoretical break”, and is highly adaptable to institutions offering distance education with no permanence requirements, that is ones offering the possibility of taking breaks. Our findings show that there are differences regarding the number of consecutive semesters that define dropout depending on whether the programme requires previous experience or not. Additionally, we observe significant differences in the dropout rate between specific programmes, as well as a higher level of dropout in the first semesters. Analyzing the reasons behind these facts should help higher education institutions to make more sound and efficient decisions.

    Sharf, Jennie; Primavera, Louis H; Diener, Marc J

    2010-12-01

    This meta-analytic review of 11 studies examined the relationship between psychotherapy dropout and therapeutic alliance in adult individual psychotherapy. Results of the meta-analysis demonstrate a moderately strong relationship between psychotherapy dropout and therapeutic alliance (d = .55). Findings indicate that clients with weaker therapeutic alliance are more likely to drop out of psychotherapy. The meta-analysis included a total of 1,301 participants, with an average of 118 participants per study, a standard deviation of 115 participants, and a range from 20 to 451 participants per study. Exploratory analyses were conducted to determine the influence of variables moderating the relationship between alliance and dropout. Client educational history, treatment length, and treatment setting were found to moderate the relationship between alliance and dropout. Studies with a larger percentage of clients who completed high school or higher demonstrated weaker relationships between alliance and dropout. Studies with lengthier treatments demonstrated stronger relationships between alliance and dropout. Inpatient settings demonstrated significantly larger effects than both counseling centers and research clinics. No significant differences were found between client-rated, therapist-rated, and observer/staff-rated alliance. Recommendations for clinicians and researchers are discussed.

    Growing evidence suggests that text messaging programs are effective in facilitating health behavior change. However, high dropout rates limit the potential effectiveness of these programs. This paper describes patterns of early dropout in the HealthyYou text (HYTxt) program, with a focus on the impact of baseline motivation quality on dropout, as characterized by Self-Determination Theory (SDT). This analysis included 193 users of HYTxt, a diet and physical activity text messaging intervention developed by the US National Cancer Institute. Descriptive statistics were computed, and logistic regression models were run to examine the association between baseline motivation type and early program dropout. Overall, 43.0% (83/193) of users dropped out of the program; of these, 65.1% (54/83; 28.0% of all users) did so within the first 2 weeks. Users with higher autonomous motivation had significantly lower odds of dropping out within the first 2 weeks. A one unit increase in autonomous motivation was associated with lower odds (odds ratio 0.44, 95% CI 0.24-0.81) of early dropout, which persisted after adjusting for level of controlled motivation. Applying SDT-based strategies to enhance autonomous motivation might reduce early dropout rates, which can improve program exposure and effectiveness.

    Researchers have suggested the rising use of Internet to look for sexual partners is an important contributor to the resurgence in the incidence of sexually transmitted diseases (STDs) and HIV among men who have sex with men (MSM). Web-based samples of this population reflect good geographical diversity for research, but a high drop-out rate creates a significant potential for bias, misrepresentation of population, and misinterpretation of data. This study aims to describe the demographics of an Internet sample of MSM and the differences between the completers and drop-outs. We analyzed data obtained from a cross-sectional study using an online self-administered questionnaire for males, 18 years or older, who were current U.S. residents, and who had sex with men. Of 850 eligible participants, 404 (47.5%) were labeled as drop-outs. The completers and drop-outs differed significantly in age, education, country of birth, health insurance, time spent on Internet, location of computer access, types of sites visited, profile information, last homosexual experience, methods used to determine safety of partners, and type of sexual activities on real meets. Almost half of the participants dropped out before completion. Although the two groups did not differ in many of the items, high drop-out rates are a threat to the validity of such data. Drop-out constitutes a significant bias in Internet sexuality research and must be considered while interpreting the results of such studies.

    This study compares two methods for handling missing data in longitudinal trials: one using the last-observation-carried-forward (LOCF) method and one based on a multivariate or mixed model for repeated measurements (MMRM). Using data sets simulated to match six actual trials, I imposed several drop-out mechanisms, and compared the methods in terms of bias in the treatment difference and power of the treatment comparison. With equal drop-out in Active and Placebo arms, LOCF generally underestimated the treatment effect; but with unequal drop-out, bias could be much larger and in either direction. In contrast, bias with the MMRM method was much smaller; and whereas MMRM rarely caused a difference in power of greater than 20%, LOCF caused a difference in power of greater than 20% in nearly half the simulations. Use of the LOCF method is therefore likely to misrepresent the results of a trial seriously, and so is not a good choice for primary analysis. In contrast, the MMRM method is unlikely to result in serious misinterpretation, unless the drop-out mechanism is missing not at random (MNAR) and there is substantially unequal drop-out. Moreover, MMRM is clearly more reliable and better grounded statistically. Neither method is capable of dealing on its own with trials involving MNAR drop-out mechanisms, for which sensitivity analysis is needed using more complex methods.

    Full Text Available El Salvador was one of three countries to receive funding from the Global Fund to Fight AIDS, Tuberculosis and Malaria to conduct a combination HIV prevention intervention among transwomen (TW, men who have sex with men (MSM, and commercial sex workers (CSW. Program evaluation revealed that prevention activities reached only 50% of the target population. The purpose of this study is to examine the barriers that Salvadoran educators faced in implementing the peer education as designed and adaptations made as a result. Between March and June 2015, 18 in-depth interviews with educators were conducted. Violence was reported as the biggest barrier to intervention implementation. Other barriers differed by subpopulation. The level of violence and discrimination calls into question the feasibility and appropriateness of peer-led interventions in the Salvadoran context and demonstrates the importance of implementation research when translating HIV prevention interventions developed in high-income countries to low- and middle-income countries.

    Increases in the sensitivity of DNA profiling technology now allow profiles to be obtained from smaller and more degraded DNA samples than was previously possible. The resulting profiles can be highly informative, but the subjective elements in the interpretation make it problematic to achieve the valid and efficient evaluation of evidential strength required in criminal cases. The problems arise from stochastic phenomena such as "dropout" (absence of an allele in the profile that is present in the underlying DNA) and experimental artefacts such as "stutter" that can generate peaks of ambiguous allelic status. Currently in the UK, evidential strength evaluation uses an approach in which the complex signals in the DNA profiles are interpreted in a semi-manual fashion by trained experts aided by a set of guidelines, but also relying substantially on professional judgment. We introduce a statistical model to calculate likelihood ratios for evaluating DNA evidence arising from multiple known and unknown contributors that allows for such stochastic phenomena by incorporating peak heights. Efficient use of peak heights allows for more crime scene profiles to be reported to courts than is currently possible. The model parameters are estimated from experimental data incorporating multiple sources of variability in the profiling system. We report and analyse experimental results from the SGMPlus system, run at 28 amplification cycles with no enhancements, currently used in the UK. Our methods are readily adapted to other DNA profiling systems provided that the experimental data for the parameter estimation is available.

    Y chromosome short tandem repeats (Y-STRs) are valuable genetic markers in certain areas of forensic case-work. However, when the Y-STR DNA profile is weak, the observed Y-STR profile may not be complete--i.e. locus drop-out may have occurred. Another explanation could be that the stain DNA did not have a Y-STR allele that was detectable with the method used (the allele is a 'null allele'). If the Y-STR profile of a stain is strong, one would be reluctant to consider drop-out as a reasonable explanation of lack of a Y-STR allele and would maybe consider 'null allele' as an explanation. On the other hand, if the signal strengths are weak, one would most likely accept drop-out as a possible explanation. We created a logistic regression model to estimate the probability of allele drop-out with the Life Technologies/Applied Biosystems AmpFlSTR(®) Yfiler(®) kit such that the trade-off between drop-outs and null alleles could be quantified using a statistical model. The model to estimate the probability of drop-out uses information about locus imbalances, signal strength, the number of PCR cycles, and the fragment size of Yfiler. We made two temporarily separated experiments and found no evidence of temporal variation in the probability of drop-out. Using our model, we found that for 30 PCR cycles with a 150 bp allele, the probability of drop-out was 1:5000 corresponding to the average estimate of the probability of Y-STR null alleles at a signal strength of 1249 RFU. This means that the probability of a null allele is higher than that of an allele drop-out at e.g. 4000 RFU and the probability of drop-out is higher than that of a null allele at e.g. 75 RFU.

    Self-reported suicidal behavior and attitudes toward suicide in psychology students are reported and compared in Ghana, Uganda, and Norway. Small differences only were found in own suicidal behavior. However, experience of suicidal behavior in the surroundings was more common in Uganda than in Ghana and Norway. Although differences were found between the three countries in attitudes toward suicide, which emphasizes the need for culture-sensitive research and prevention, many of the differences were not as big as expected. The most pronounced difference was that the Norwegian students were more reluctant to take a stand on these questions compared to their African counterparts. Some differences were also found between the two African countries. The implications of the results for suicide prevention in Africa are discussed.

    The objective of this study was to investigate the prevalence of discontinuation in the smoking cessation outpatient clinic (SCC) and to examine the features of noncompliance. We retrospectively included 1324 smokers into the study. Patients were divided into two groups, as those who discontinued (dropped out) follow-up (group 1) and those who stayed in follow-up (group 2). Of the total 1324 smokers, 540 (40.8%) patients were in group 1. The mean age, smoking pack-years, and Fagerstrom scores of group 1 were lower than group 2 (p = 0.001, p = 0.008, and p = 0.007, respectively). In addition, the choice of treatment was also different between groups (p 0.05). Almost 40% of our patients did not come to their follow-up SCC visit. Younger age, lower Fagerstrom score, low amount of daily cigarette consumption, and being treated only with behavioral therapy or NRT were detected as the characteristics of the dropout group. Awareness of the characteristics of smokers who drop out of SCC programs may provide for the implementation of personalized treatment at the first appointment. © The Author(s) 2016.

    Background Patient dropout from treatment can lead to a deterioration in clinical condition, thereby increasing the need for more intensive therapy that incurs substantial social and economic losses. The aim of this study was to identify factors related to psychiatric patient dropout at a university outpatient clinic in Japan. Methods We retrospectively examined the medical charts of new psychiatric patients who were diagnosed with either a mood disorder (International Classification of Diseases, 10th revision, code: F3) or an anxiety disorder (F4) in the outpatient clinic at Kyoto Prefectural University of Medicine Hospital in Kyoto, Japan, between April 2010 and March 2013. The baseline characteristics of the patients (age, sex, Global Assessment of Functioning score, Clinical Global Impression–Severity of Illness score, education, occupation, marital status, duration of treatment, and prior treatment history), treating psychiatrist experience in years, and sex concordance between the patients and their treating psychiatrists were analyzed using Cox regression models. Results From among 1,626 eligible new patients during the study period, 532 patients were enrolled in the study (F3: n=176; F4: n=356). The dropout rate was 35.7%, which was similar to that of previous studies. Higher educational level, being married, and lower Global Assessment of Functioning scores were associated with a lower dropout rate. Although psychiatrist experience was not significantly associated with patient dropout in the multivariate analysis, patients treated by less experienced psychiatrists had a higher hazard ratio for dropout (1.31; 95% confidence interval: 0.94–1.85). Conclusion In order to reduce the dropout rate, special focus should be placed on patients with the factors identified in this study, and young psychiatrists should undergo further education to foster adherence.

    Determining redshifts for BL Lacertae (BL Lac) objects using the traditional spectroscopic method is challenging due to the absence of strong emission lines in their optical spectra. We employ the photometric dropout technique to determine redshifts for this class of blazars using the combined 13 broadband filters from Swift-UVOT and the multi-channel imager GROND at the MPG 2.2 m telescope at ESO's La Silla Observatory. The wavelength range covered by these 13 filters extends from far-ultraviolet to the near-infrared. We report results on 40 new Fermi-detected BL Lacs with the photometric redshift determinations for five sources, with 3FGL J1918.2–4110 being the most distant in our sample at z = 2.16. Reliable upper limits are provided for 20 sources in this sample. Using the highest energy photons for these Fermi-LAT sources, we evaluate the consistency with the gamma-ray horizon due to the extragalactic background light.

  14. 'He is the one who is providing you with everything so whatever he says is what you do': A Qualitative Study on Factors Affecting Secondary Schoolgirls' Dropout in Rural Western Kenya.

    Directory of Open Access Journals (Sweden)

    Kelvin Oruko

    Full Text Available Education is an effective way to improve girls' self-worth, health, and productivity; however there remains a gender gap between girls' and boys' completion of school. The literature around factors influencing girls' decision to stay in school is limited. Seven focus group discussions took place among 79 girls in forms 2 to 4 at secondary schools in rural western Kenya, to examine their views on why girls absent themselves or dropout from school. Data were analysed thematically. Lack of resources, sexual relationships with boyfriends, and menstrual care problems were reported to lead directly to dropout or school absence. These were tied to girls increased vulnerability to pregnancy, poor performance in school, and punishments, which further increase school absence and risk of dropout. Poverty, unmet essential needs, coercive sexual relationships, and an inequitable school environment collude to counter girls' resolve to complete their schooling. Lack of resources drive girls to have sex with boyfriends or men who provide them with essentials their family cannot afford, such as sanitary pads and transport to school. While these improve quality of their school life, this dynamic increases their exposure to sexual risk, pregnancy, punishment, and dropout. Evaluation of interventions to ameliorate these challenges is warranted, including provision of pocket money to address their needs.

  15. Self-reported osteoporosis prevention in inhaled corticosteroid users in community pharmacy setting

    Directory of Open Access Journals (Sweden)

    Valerie Chan

    2015-05-01

    Full Text Available Objectives: The use of inhaled corticosteroids is the standard maintenance therapy in asthma therapy and as adjunct therapy in moderate to severe chronic obstructive pulmonary disease. A dose-related increase in fracture risk is associated with inhaled corticosteroid use; there is an inverse relationship between bone mineral density and duration and cumulative dose of inhaled corticosteroid. Adequate intake of calcium and vitamin D are cornerstones of osteoporosis prevention. The objectives are to assess whether the proportion of patients receiving inhaled corticosteroids are taking calcium and vitamin D; the association between long-term inhaled corticosteroid use and abnormal bone mineral density or fractures; and how many qualified patients received bone mineral density scans. Methods: Patients who filled a prescription for inhaled corticosteroids at selected community pharmacies across Alberta were recruited for a survey of their osteoporosis prevention activities. Results: A total of 256 patients from 12 community pharmacies were included. The average age was 60 ± 17.4 years with 65% female. There were 21%, 51%, and 28% of patients on high, medium, and low dose inhaled corticosteroids, respectively. Only 17% of patients >50 years old received recommended calcium and vitamin D supplementation and 87 (73% of the qualified patients received bone mineral density scan. Conclusion: Osteoporosis prevention in inhaled corticosteroid users is currently poorly addressed. More promotion is needed to raise pharmacist awareness of the risks of inhaled corticosteroids.

    Globally, dementia is the most frequent form of degenerative condition in the older adult population and poses a major health burden with high socioeconomic costs. So far, attempts to find pharmacologic interventions that can change the onset or progression of dementia have been largely unsuccessful, prompting a shift to focus on interventions aimed at modifying risk factors that occur throughout the life course. The Cognitive Function and Ageing Studies, funded by the Medical Research Council, UK, convened three multidisciplinary groups of experts, expert witnesses, and advocates to discuss the state of evidence on primary, secondary, and tertiary dementia prevention and recommend future direction for intervention studies. Using the United Kingdom Parliamentary Select Committees' approach to gathering evidence, the primary prevention working group focused their deliberation on risk factors strongly associated with dementia. The group highlighted the need for high-quality studies to assess the effects of behavioral intervention on the delay of cognitive decline and dementia onset. The working group recommended that the development of a future dementia prevention trial should use a multimodal, multifactor, multilevel, community and individually tailored approach.

    AKI is an important clinical problem that has become increasingly more common. Mortality rates associated with AKI remain high despite advances in supportive care. Patients surviving AKI have increased long-term mortality and appear to be at increased risk of developing CKD and progressing to ESRD. No proven effective pharmacologic therapies are currently available for the prevention or treatment of AKI. Advances in addressing this unmet need will require the development of novel therapeutic agents based on precise understanding of key pathophysiological events and the implementation of well designed clinical trials. To address this need, the National Institute of Diabetes and Digestive and Kidney Diseases sponsored the "Clinical Trials in Acute Kidney Injury: Current Opportunities and Barriers" workshop in December 2010. The event brought together representatives from academia, industry, the National Institutes of Health, and the US Food and Drug Administration. We report the discussions of workgroups that developed outlines of clinical trials for the prevention of AKI in two patient populations: patients undergoing elective surgery who are at risk for or who develop AKI, and patients who are at risk for contrast-induced AKI. In both of these populations, primary prevention or secondary therapy can be delivered at an optimal time relative to kidney injury. The workgroups detailed primary and secondary endpoints for studies in these groups, and explored the use of adaptive clinical trial designs for trials of novel preventive strategies to improve outcomes of patients with AKI.

    School dropout in adolescence is an important social determinant of health inequality in a lifetime perspective. It is commonly accepted that parental background factors are associated with later dropout, but to what extent social relations mediate this association is not yet fully understood. To investigate the effect of social relations on the association between parental socioeconomic position and school dropout in the Danish youth cohort Vestliv. This prospective study used data from questionnaires in 2004 and 2007 and register data in 2004 and 2010. The study population consisted of 3,054 persons born in 1989. Information on dropout was dichotomised into those who had completed a secondary education/were still attending one and those who had dropped out/had never attended a secondary education. Logistic regression analyses were used to investigate associations between parental socioeconomic position and dropout at age 21, taking into account effects of social relations at age 15 and 18. A large proportion of young people were having problems with social relations at age 15 and 18. In general, social relations were strongly related to not completing a secondary education, especially among girls. For instance, 18-year-old girls finding family conflicts difficult to handle had a 2.6-fold increased risk of not completing a secondary education. Young people from low socioeconomic position families had approximately a 3-fold higher risk of not completing a secondary education compared to young people from high position families, and the estimates did not change greatly after adjustment for social relations with family or friends. Poor relations with teachers and classmates at age 18 explained a substantial part of the association between income and dropout among both girls and boys. The study confirmed a social gradient in completion of secondary education. Despite the fact that poor social relations at age 15 and 18 were related to dropout at age 21, social

    A study was undertaken in the province of Bukidnon in the Philippines to determine the actual percentage of family planning (FP) acceptors who become dropouts, the reasons they drop out, and the factors most strongly associated with this phenomenon. Data were collected through interviews with married women of reproductive age who had been recorded as being a FP acceptor during 1992. The sample size was set at 400 using a probability-proportionate-to-size sampling technique. In examining the extent of the drop-out problem, it was found that the actual FP status of each respondent agreed with the clinic records in 73.4% of cases and that 22% of those thought to be dropouts had actually switched methods. Most of the women who stopped using oral contraceptives said they did so because of side effects. The drop-out problem was most acute among women who were poorer, less educated, and of higher parity. The attitude of a husband towards use of a method was a better predictor of continuation than the wife's attitude. Clients who felt their provider was approachable and friendly were significantly less likely to drop out. Despite the fact that the FP program is modeled on a "cafeteria" approach which provides choices to acceptors, 9.5% of acceptors in this survey claimed they were not offered a choice. Women who received limited information were more likely to become drop-outs. Clients who had to return to clinics frequently for resupply of OCs or condoms were most likely to become drop-outs. While the number of dropouts identified in this study was only half the official estimate for the province, the short time between FP acceptance and the survey may have reduced the number of dropouts. The program implications of these findings are that 1) the occurrence of side effects needs study, 2) groups characterized by high drop-out rates should receive immediate attention, 3) favorable attitudes should be fostered in husbands, 4) women must receive more information on their

    The Hong Kong news media report suicide-related events more frequently and sensationally than Western countries. Little is known about Hong Kong media professionals' experiences and thoughts about such reporting. To understand Hong Kong media professionals' experiences and perceptions of suicide reporting and whether the news media can be better engaged into suicide prevention. We conducted three focus groups of journalists from both the Cantonese and English language news media. Data were analyzed using grounded theory methods. We discerned three rationales from participants regarding their intense coverage of suicide-related events: (1) satisfying commercial competitiveness, (2) addressing social problems, and (3) responding to readers' interests. The first rationale was a dominant and vigorous motivating factor, and often influenced suicide reporting among local Cantonese media. Media professionals recommended engagement strategies targeted at frontline journalists, media managers, and general media consumers. We see potential to involve news media professionals in Hong Kong as working partners in suicide prevention. To succeed, this effort requires engagement in a proactive, consistent, and sustained fashion.

    Full Text Available Background. Resistance exercise training can be effective against sarcopenia. We identified predictors of drop-out and compared physical outcomes between men and women after such training. Methods. Subjects (N=236, 73.7±5.7 years participated in a 12-week resistance exercise program. Outcome variables were measured at baseline and endpoint. Results. Drop-out was 11.9% and not significantly different between genders. Drop-outs were significantly older and had poorer strength and physical function in comparison to completers. Anthropometrics, QoL, and cognitive function were not related to drop-out. According to multivariate analysis, gait speed and physical activity were the strongest predictors of drop-out. After the training, gains in lean mass or appendicular muscle were significantly higher in men than women; however relative gains in appendicular muscle as well as absolute improvements in strength and function were similar in men and women, respectively. Conclusions. Participants who drop out are older, have poorer physical function, and are less physically active. Old women do not drop out more frequently than men and show meaningful improvements in relevant outcomes similar to men after such a training program. The trial is registered at the US National Library of Medicine (NCT01074879.

    Full Text Available This paper is concerned with the problem of modeling and output feedback controller design for a class of discrete-time networked control systems (NCSs with time delays and packet dropouts. A Markovian jumping method is proposed to deal with random time delays and packet dropouts. Different from the previous studies on the issue, the characteristics of networked communication delays and packet dropouts can be truly reflected by the unified model; namely, both sensor-to-controller (S-C and controller-to-actuator (C-A time delays, and packet dropouts are modeled and their history behavior is described by multiple Markov chains. The resulting closed-loop system is described by a new Markovian jump linear system (MJLS with Markov delays model. Based on Lyapunov stability theory and linear matrix inequality (LMI method, sufficient conditions of the stochastic stability and output feedback controller design method for NCSs with random time delays and packet dropouts are presented. A numerical example is given to illustrate the effectiveness of the proposed method.

    Full Text Available Aim of the study: The problem of premature ending of therapy is a common phenomenon and is taken under consideration as closely related to effectiveness of therapy. The crucial aim of presented study was to investigate how members of a family interpret this phenomenon. Subject and methods: The research was based on interviews with drop-out clients who had participated in systematic couple therapy. The qualitative data was analyzed using the four stages methodology of grounded theory. The program used to code the data was Weft QDA. Results: The result pointed out, that drop-out from therapy is a procesual phenomenon and is connected with: a context of application, a kind of relationship between partners, an assessment of therapy. It was confirmed in the research group that the level of satisfaction from effects of therapy was related to premature termination. Discussion: The research indicated how consequences of drop-out can affect the family system. Conclusions: The high frequency of positive emotions and opinions occurring in drop-out context shows that drop-out phenomenon should not be considered only as a therapeutic failure.

    A prospective survey of patient drop-outs was carried out in a palliative care setting to understand the background of patients in the drop-out category. This was to understand the background of patients who drop out and why they drop out. The survey was conducted on 425 patients who had registered in the clinic in 2009 and subsequently persistently dropped out. Patients were classified on the basis of age, gender, education, disease, socioeconomic class, distance from clinic to home, family size, general health on the basis of symptoms on first arrival, reasons subsequently found for missing the appointment, primary caregiver details, and social support. The data were collected, and analyzed statistically using chi-square tests and percentages. Majority of patients presented in the 41- to 60-year age group had secondary level education, with a family size of four. The drop-out rate was 25.06%. There was a significant association (P = 0.026) between reasons for dropping out and social support. A P-value drop-out rate decreases. Majority of patients discontinued because a similar facility became available nearer their residence. A number of palliative care clinics have been created in the district and this has resulted in the significant drop-out rate.

    Little is known about the amount and quality of after-care provided for patients hospitalised as a result of a court authorisation. To obtain insight into the rate of drop-out from after-care and the quality of after-care. In our study we included all patients in Rotterdam Rijnmond who, in the last 3 months of 2004, had been compulsorily hospitalised for at least one day by reason of a court authorisation. A retrospective study of patients' records let us ascertain whether drop-out from after-care occurred and let us check on the quality of the after-care provided. 214 patients were included. Of these, 33 (15.4%) dropped out of after-care. Prior to discharge, the drop-out group received an outpatient appointment at a local clinic less often and waited longer for their first appointment at that clinic than did the 'non-drop-out' group. The medical records of the drop-out group were less accurate and there was less cooperation between community care and clinical mental health care professionals. The quality of after-care can be improved if community care and clinical health care professionals cooperate more intensively in drawing up conditions for discharge and in arranging the transfer of patients from clinical care to community care. Further investigations are needed to find out whether these steps will have a beneficial effect on the drop-out percentage.

    Drop-out from treatment is a serious problem in eating disorders which remains poorly understood. The present study investigated whether self-image and interpersonal theory could help to explain why eating disorder patients drop out of treatment. Intake data on eating disorder patients who terminated treatment prematurely (N=54) were compared with patients who had completed treatment (N=54) and those who were still in treatment after 12 months (N=54). Self-image was assessed using the structural analysis of social behaviour (SASB), and comparisons were made on demographic and clinical variables. Patients who dropped out had initially presented with less negative self-image and fewer psychological problems compared with remainers. Low levels of SASB self-blame discriminated drop-outs from completers and remainers and significantly predicted treatment drop-out. Drop-out in eating disorders appears to be a complex phenomenon, not necessarily as pathological as often assumed. There may be important differences in the treatment goals of drop-outs and therapists; patients who drop out may be choosing to disengage at a time when symptom improvement creates space for closer examination of interpersonal issues.

    Obesity is increasing in the elderly and it is associated with an increased risk of medical complications, decline in physical function and disability. Very few studies specifically evaluated the outcome of obesity treatment in the aging patients. Aim of this work is therefore the evaluation of the efficacy of medical therapy in a group of obese patients >or=65 years old. The study has been performed on the clinical records of obese outpatients treated at the medical branch of the Unit for Medical and Surgical Therapy of Obesity at the University of Padova. Patients were recruited from January 1st, 2001 to June 30th, 2006 in order to have patients with at least one year of potential follow-up. In particular two groups were enrolled: 100 patients >or=65 years old and 200 patients drop-out rate after 12 months was similar in adults (77%) and in older patients (72%). In a multivariate Cox regression model, the risk of drop-out was reduced by married or widowed status, the prescription of physical activity at baseline, and the presence of type 2 diabetes. The risk of drop-out was increased by the presence of osteoarthritis. Even after adjustments for these confounding variables, age did not play any significant role as drop-out predictor. Advanced age seems to be a predictor of poor response to treatment in obese outpatients treated by conventional medical therapy. Drop-out rate was not significantly influenced by age.

    Complete cure of mycetoma is difficult to achieve and recurrence is common. The study objective was to determine the predictors of cure, amputation and follow-up dropout among the studied individuals with mycetoma. This prospective study included 1544 patients with confirmed mycetoma, of whom 1242 had eumycetoma and 302 actinomycetoma. They were treated and followed up regularly. Data were collected and analysed using logistic regression models to determine the predictors. In the eumycetoma group, longer treatment duration (OR=1.9; 95% CI 1.2-3.1) and absence of history of disease recurrence (OR=24.2; 95% CI 7.7-76.3) were significant predictors of increased odds of cure from mycetoma. A lesion size of 5-10 cm (OR=0.5; 95% CI 0.3-0.8) or >10 cm (OR=0.7; 95% CI 0.4-1.0) and combined medical treatment and surgery (OR=0.004; 95% CI 0.001-0.011) were each significant predictors of reduced odds of cure. Follow-up dropout among this group was high (54%). Large lesions (5-10 cm, OR=0.5, 95% CI 0.4-0.7; >10 cm, OR=0.6; 95% CI 0.5-0.9), amputations (OR=0.3; 95% CI 0.1-0.6) and longer treatment duration (OR=0.5; 95% CI 0.4-0.7) were significant predictors of reduced odds of follow-up dropout. In the actinomycetoma group, medical treatment was the only significant predictor of cure. Follow-up dropout among this group was also high (55.6%). Long treatment duration was a significant predictor of reduced odds of dropout (OR=0.5; 95% CI 0.3-0.8). There is a great demand for effective and efficient mycetoma treatment. Counselling and health education of patients is badly needed to encourage early reporting and treatment to reduce mycetoma's medical, social and economic impacts.

    Full Text Available Abstract Background Aldosterone levels are elevated in a rat model of type 2 diabetes mellitus, the Zucker Diabetic fatty rat (ZDF. Moreover blood pressure in ZDF rats is salt-sensitive. The aim of this study was to examine the effect of the aldosterone antagonist eplerenone on structural and mechanical properties of resistance arteries of ZDF-rats on normal and high-salt diet. Methods After the development of diabetes, ZDF animals were fed either a normal salt diet (0.28% or a high-salt diet (5.5% starting at an age of 15 weeks. ZDF rats on high-salt diet were randomly assigned to eplerenone (100 mg/kg per day, in food (ZDF+S+E, hydralazine (25 mg/kg per day (ZDF+S+H, or no treatment (ZDF+S. Rats on normal salt-diet were assigned to eplerenone (ZDF+E or no treatment (ZDF. Normoglycemic Zucker lean rats were also divided into two groups receiving normal (ZL or high-salt diet (ZL+S serving as controls. Systolic blood pressure was measured by tail cuff method. The experiment was terminated at an age of 25 weeks. Mesenteric resistance arteries were studied on a pressurized myograph. Specifically, vascular hypertrophy (media-to-lumen ratio and vascular stiffness (strain and stress were analyzed. After pressurized fixation histological analysis of collagen and elastin content was performed. Results Blood pressure was significantly higher in salt-loaded ZDF compared to ZDF. Eplerenone and hydralazine prevented this rise similarily, however, significance niveau was missed. Media-to-lumen ratio of mesenteric resistance arteries was significantly increased in ZDF+S when compared to ZDF and ZL. Both, eplerenone and hydralazine prevented salt-induced vascular hypertrophy. The strain curve of arteries of salt-loaded ZDF rats was significantly lower when compared to ZL and when compared to ZDF+S+E, but was not different compared to ZDF+S+H. Eplerenone, but not hydralazine shifted the strain-stress curve to the right indicating a vascular wall composition

    Full Text Available We report the case study of a school-aged child with autism whose repetitive behaviors were treated with a modified version of a technique routinely used in cognitive behavior therapy (i.e., exposure response prevention to treat obsessive-compulsive disorder. A trained behavioral therapist administered the modified ERP treatment over the course of an intensive two-week treatment period with two therapy sessions occurring daily. The treatment was successful at decreasing the amount of child distress and cooccurring problem behavior displayed; however, the child's interest in the repetitive behavior eliciting stimulus (i.e., puzzles remained. The case study demonstrates specific ways that exposure response prevention strategies can be adapted to the unique kinds of repetitive behaviors that present clinically in autism. A larger clinical trial is needed to substantiate these findings.

    Moderate and chronic paronychia is a common disease affecting the hand. Treatment can be effective but the affection is often recurrent, especially as an occupational disease. Moreover, this condition may be complicated by a Candida spp or by bacterial infections. Therefore, general preventive measures can be useful in maintaining health. The aim of this study was to investigate the efficacy and tolerability of a new combination of topical medications in the treatment and prevention of moderate and chronic paronychia. This formulation includes an insulating polymer (Syn-cell barrier), two topical antifungals (octopirox and climbazole) and a molecule with anti-inflammatory activity (corticoid-like repair). Thirty adult subjects (age, 16-78 years; 24 females and 6 males) affected by moderate or chronic paronychia, with or without nail alterations, were evaluated. Included in the study were patients with allergic contact dermatitis (8), irritant contact dermatitis (19), psoriatic paronychia (2 patients), lichen planus of the nails (1 patient). Sometimes Candida spp or bacteria overlapped with paronychia (16 patients positive for Candida spp and 4 patients with bacterial paronychia), sometimes infectious paronychia was not associated with dermatitis of the hands. All 30 subjects were treated with a new cream formulation, three applications per day for 2 months. In 8 patients with proven and severe candidiasis of the nails, oral fluconazole 100 mg was added for 20 days. All patients with bacterial perionyxis took clarithromycin 500 mg twice daily for six days. Patients were then followed for 8 weeks. After two months of treatment, 26 patients responded to therapy. In particular, the treatment evaluation at the end of the follow-up period showed a clinical cure in 46.6% (14 patients), improvement in 40% (12 patients), and failure in 13.4% (4 patients). There was a side effect (moderate skin irritation) in 2 patients, but the drug was not discontinued. Results of the

    The objective of this study was to describe the impact of intense counseling to reduce vaginal hygiene practices and its effect on bacterial vaginosis. A secondary data analysis of the HIV Prevention Trials Network 035 study was undertaken, focusing on HIV-negative, nonpregnant women who were at least 18 years old, in seven African sites and one US site. At enrollment and during follow-up quarterly visits, vaginal hygiene practices were determined by face-to-face administration of a behavioral assessment questionnaire. Vaginal hygiene practices were categorized as insertion into the vagina of (1) nothing, (2) water only, and (3) other substances with or without water. Each practice was quantified by frequency and type/combination of inserted substances. At quarterly visits, diagnosis of bacterial vaginosis was made using the Nugent score. Trends for vaginal hygiene practices and bacterial vaginosis were evaluated using generalized estimating equation models. A total of 3087 participants from the HIV Prevention Trials Network 035 study were eligible for this analysis. At enrollment, 1859 (60%) reported recent vaginal hygiene practices. By one year, this figure had decreased to 1019 (33%) with counseling. However, bacterial vaginosis prevalence remained consistent across the study observation period, with 36%-38% of women testing positive for the condition ( p for trend = 0.27). Overall, those who reported douching with water only (AOR = 1.03, 95%CI: 0.94-1.13) and those who reported inserting other substances (AOR= 0.98, 95%CI: 0.88-1.09) in the past quarter were not more likely to have bacterial vaginosis compared to those who reported no insertions. However, in South Africa, an increase in bacterial vaginosis was seen among those who reported inserting other substances (AOR: 1.48, 95%CI: 1.17, 1.88). In conclusion, targeted counseling against vaginal hygiene practices resulted in change in self-reported behavior but did not have an impact on bacterial vaginosis

    The transition to studying at university is associated with increased levels of both stress and hazardous alcohol use. The aim of this study is to investigate the influence of these factors on first-year dropout from university studies. Two complete cohorts of university freshmen at two homogeneous universities, one in the north and one in the south of Sweden, were asked to participate in an intervention study. Participants responded to a baseline questionnaire including measures of stress and alcohol use. Official university records showing dropout over 12 months were collected. A multivariate analysis established that high stress and admission to the northern university were associated with dropout from university studies, while symptoms of depression and anxiety as well as hazardous drinking were not. There is a need to address the issue of stress associated with the start of university studies. It seems important to offer stress-reducing interventions, specifically aimed at reducing transitional stress, as soon as students start university.

  19. Dynamic Average Consensus and Consensusability of General Linear Multiagent Systems with Random Packet Dropout

    Directory of Open Access Journals (Sweden)

    Wen-Min Zhou

    2013-01-01

    Full Text Available This paper is concerned with the consensus problem of general linear discrete-time multiagent systems (MASs with random packet dropout that happens during information exchange between agents. The packet dropout phenomenon is characterized as being a Bernoulli random process. A distributed consensus protocol with weighted graph is proposed to address the packet dropout phenomenon. Through introducing a new disagreement vector, a new framework is established to solve the consensus problem. Based on the control theory, the perturbation argument, and the matrix theory, the necessary and sufficient condition for MASs to reach mean-square consensus is derived in terms of stability of an array of low-dimensional matrices. Moreover, mean-square consensusable conditions with regard to network topology and agent dynamic structure are also provided. Finally, the effectiveness of the theoretical results is demonstrated through an illustrative example.

This study of Danish vocational education policy examines both (i) how student attrition has been framed in different periods, and (ii) the solutions that have been prescribed in accordance with shifting conceptualisations of early school leaving. The author’s inquiry...... finds that the rate of student drop-out has been a cause for ongoing concern among policy makers for more than a century, and that the framing of the problem has shifted considerably over time. The problem has variously been placed with the individual apprentice, the basic structure of vocational...

    Premature drop-out from treatment is a highly prevalent phenomenon among eating disorder (ED) patients. In a specialized inpatient treatment unit a major change was made in the admission strategy in 2001, giving a maximum of personal choice to the patients. A quasi-experimental research was carried out comparing 87 patients treated till 2000 ('old' strategy) with 87 patients treated from 2001 on ('new' strategy). The results indicate that the provision of choice at the beginning of treatment significantly reduced drop-out during the first weeks of inpatient treatment. No differences between both strategies on later drop-out and weight change (in anorexia nervosa patients) during inpatient treatment were found. The results are discussed in the light of the importance placed on dynamics of personal choice, autonomy and volition within the framework of the self-determination theory (SDT).

    The efficacy of CBT for unipolar depressive disorders is well established, yet not all patients improve or tolerate treatment. To identify factors associated with symptomatic outcome, response, and drop-out in depressive patients under naturalistic CBT. 193 patients with major depression or dysthymia were tested. Sociodemographic and clinical variables were entered as predictors in hierarchical regression analyses. A higher degree of pretreatment depression, early improvement, and completion of therapy were identified as predictors for symptomatic change and response. Drop-out was predicted by concurrent personality disorder, less positive outcome expectancies, and by failure to improve early in treatment. Our results highlight the importance of early response to predict improvement in routine CBT. Attempts to refine the quality of treatment programs should focus on avoiding premature termination (drop-out) and consider motivational factors in more depth. Routinely administered standardized assessments would enhance symptom monitoring and help to identify persons at risk of not improving under therapy.

    Background Long-term use of antiplatelet agents,statins,beta-blockers and angiotensin-converting enzyme inhibitors are proven therapies for secondary prevention in acute coronary syndrome.However,little is known of physicians' opinion about their use in China.Methods In 2010,standard questionnaires were posted to chief cardiologists in 1397 geographically diverse and representative sample of tertiary and secondary hospitals in China,collecting information about their opinions on the recommended treatments for acute coronary syndrome.Results A total of 1009 (72%) cardiologists responded with a valid questionnaire.Of them,77% reported routine use of all the four main secondary preventive treatments,with little difference between secondary and tertiary hospitals (75% vs.79%,P=0.16).Of the cardiologists reporting routine or selective use of aspirin,beta-blockers,statins and angiotensin-converting enzyme inhibitors,94%,85%,73% and 86% would recommend indefinite use respectively.For all the 4 treatments combined,only 63.5% reported indefinite use at the same time,with no significant difference between secondary and tertiary hospitals (62% vs.65%,P=0.17),nor between hospitals with or without fast track for primary percutaneous coronary intervention (66% vs.61%,P=0.50).Conclusions Although Chinese cardiologists seem well informed about the value of main secondary preventive treatments for acute coronary syndrome,there is still gap in their understanding of the need for combined and prolonged use of these treatments.

    Full Text Available A reasonable estimation of expected dropout rates is vital for adequate sample size calculations in randomized controlled trials (RCTs. Underestimating expected dropouts rates increases the risk of false negative results while overestimating rates results in overly large sample sizes, raising both ethical and economic issues. To estimate expected dropout rates in RCTs on yoga interventions, MEDLINE/PubMed, Scopus, IndMED, and the Cochrane Library were searched through February 2014; a total of 168 RCTs were meta-analyzed. Overall dropout rate was 11.42% (95% confidence interval [CI] = 10.11%, 12.73% in the yoga groups; rates were comparable in usual care and psychological control groups and were slightly higher in exercise control groups (rate = 14.53%; 95% CI = 11.56%, 17.50%; odds ratio = 0.82; 95% CI = 0.68, 0.98; p=0.03. For RCTs with durations above 12 weeks, dropout rates in yoga groups increased to 15.23% (95% CI = 11.79%, 18.68%. The upper border of 95% CIs for dropout rates commonly was below 20% regardless of study origin, health condition, gender, age groups, and intervention characteristics; however, it exceeded 40% for studies on HIV patients or heterogeneous age groups. In conclusion, dropout rates can be expected to be less than 15 to 20% for most RCTs on yoga interventions. Yet dropout rates beyond 40% are possible depending on the participants’ sociodemographic and health condition.

    In the present study, drop-out-analyses were carried out for a manual-based cognitive-behavioral therapy for 104 females with anorexia nervosa (AN) and bulimia nervosa (BN), in the service setting of a university outpatient clinic (naturalistic setting). A total of 22.9% of patients with AN terminated therapy prematurely (drop-outs), compared to 40.6% of patients with BN. Group differences between drop-outs and completers show that the group of drop-outs with BN had higher values in the depression score at the start of therapy and was almost two times more likely to have a comorbid disorder (odds ratio 1.69), whereas drop-outs with AN had higher values in the outcome-scale drive for thinness and the odds ratio for being employed or living in a partnership was slightly lower. Completers and drop-outs did not differ significantly within groups in regard to age, body mass index at the start and end of therapy, or the number of comorbid disorders. On the whole, the therapy effect in the group of drop-outs was relatively moderate. For patients with AN, even higher therapy effects were observed among the drop-outs than among the completers. These data suggest that moderate therapy effects and responses can be achieved even among the drop-outs.

    2017-02-01

    The reporting of suspected CSA cases to authorities in a timely manner is important in preventing continued abuse and protecting abused children at early ages. The current study seeks to explore parents' intentions of reporting their own children's CSA experiences to authorities as well as their reporting willingness when they become aware of possible CSA cases happening to children in other families. Two rounds of semi-structured interviews were conducted among a sample of 26 parents in Beijing; these parents were purposefully selected so as to be diverse in terms of gender, age, and socioeconomic status. The data were analyzed thematically. The findings showed that the reporting of suspected CSA to authorities was a choice made by only a few Chinese parents; it was often even a last resort. By using a holistic-interactionistic approach, the interaction between Chinese parents' intentions of reporting CSA and the Chinese socio-cultural context was analyzed as a dynamic and continuously ongoing process. The impacts of the definition and perceptions of CSA on reporting, the balance of children's rights and parents' power, and the double effect of informal social control are discussed. The implications, both locally and globally, are also discussed. Copyright © 2016 Elsevier Ltd. All rights reserved.

    We simulate trajectories of energetic particles from impulsive solar flares for 2D+slab models of magnetic turbulence in spherical geometry to study dropout features, i.e., sharp, repeated changes in the particle density, and the particles' lateral transport. Among random-phase realizations of 2D turbulence, a spherical harmonic expansion can generate homogeneous turbulence over a sphere, but a 2D fast Fourier transform (FFT) locally mapped onto the lateral coordinates in the region of interest is much faster computationally, and we show that the results are qualitatively similar. We then use the 2D FFT field as input to a 2D MHD simulation, which dynamically generates realistic features of turbulence such as coherent structures. The magnetic field lines and particles spread non-diffusively (ballistically) to a patchy distribution reaching up to 25° from the injection longitude and latitude at r 1 AU. This dropout pattern in field line trajectories has sharper features in the case of the more realistic 2D MHD model, in better qualitative agreement with observations. The initial dropout pattern in particle trajectories is relatively insensitive to particle energy, though the energy affects the pattern's evolution with time. We make predictions for future observations of solar particles near the Sun (e.g., at 0.25 AU), for which we expect a sharp pulse of outgoing particles along the dropout pattern, followed by backscattering that first remains close to the dropout pattern and later exhibits cross-field transport to a distribution that is more diffusive, yet mostly contained within the dropout pattern found at greater distances.

    Full Text Available Abstract Background To improve and assess the effectiveness of disease management programs (DMPs, it is critical to understand how many people drop out of disease management programs and why. Methods We used routine data provided by a statutory health insurance fund from the regions North Rhine, North Wurttemberg and Hesse. As part of the German DMP for type 2 diabetes, the insurance fund received regular documentation of all members participating in the program. We followed 10,989 patients who enrolled in the DMP between July 2004 and December 2005 until the end of 2007 to study how many patients dropped out of the program. Dropout was defined based on the discontinuation of program documentation on a particular patient, excluding situations in which the patient died or left the insurance fund. Predictors of dropout, assessed at the time of program enrolment, were explored using logistic regression analysis. Results 5.5% of the patients dropped out of the disease management program within the observation period. Predictors of dropout at the time of enrolment were: region; retirement status; the number of secondary diseases; presence of a disabling secondary disease; doctor's recommendations to stop smoking or to seek nutritional counselling; and the completion and outcome of the routine foot and eye exams. Different trends of dropout were observed among retired and employed patients: retired patients of old age, who possibly drop out of the program due to other health care priorities and employed people of younger age who have not yet developed many secondary diseases, but were recommended to change their lifestyle. Conclusions Overall, dropout rates for the German disease management programs for type 2 diabetes were low compared to other studies. Factors assessed at the time of program enrolment were predictive of later dropout and should be further studied to provide information for future program improvements.

    To study the result and the mechanism of preventing postoperative adhesion after orbit trauma by chitosan membrane, and to observe the effects of chitosan membrane on optic nerve and visual function. It was a self-control trail. Ten white rabbits (twenty eyes) were adopted in this experiment. Right eye on each rabbit was used in chitosan membrane experiment group and the left eye in control group. Trauma was made between superior rectus muscle and corresponding periosteum. Chitosan membrane was implanted between trauma tissues in the experimental group. F-VEP was tested 1 day before the operation and 6 days after operation in each rabbits. Degree of adhesion was evaluated by naked eyes; inflammatory score was evaluated by pathological examination and TGF-p3 impression was evaluated by immunohistochemical studies. F-VEP examination 6 days after the operation showed that the wave amplitude of Pt1 was (9.847 +/- 2.320) mV, latency of P1 was (71.700 +/- 5.144) ms. There was no difference between pre- and post-operative data (t = 0.974, 0.228; P > 0.01). Adhesion degree evaluation showed that there were 7 eyes with 1 score, 3 eyes with 2 score in the experimental group; while there were 1 eye with 2 score, 5 eyes with 3 score, 4 eyes with 4 score in the control group. There was a statistically significant difference (T = 59.00, P eyes with 1 score, 4 eyes with 2 score in experimental group; while 2 eyes with 1 score, 4 eyes with 2 score, 4 eyes with 3 score in the control group. Immunohistochemical study showed strong positive in all slides of the experimental group, while only weakly positive in the control group. Chitosan membrane is effective on decreasing the synthesis of collagen fibrils and preventing adhesion after the orbit trauma in the rabbits.

    2011-02-01

    We consider repeated measures interval-observed data with informative dropouts. We model the repeated outcomes via an unobserved random intercept and it is assumed that the probability of dropout during the study period is linearly related to the random intercept in a complementary log-log scale. Assuming the random effect follows the power variance function (PVF) family suggested by Hougaard (2000), we derive the marginal likelihood in a closed form. We evaluate the performance of the maximum likelihood estimation via simulation studies and apply the proposed method to a real data set.

    Full Text Available Abstract Background The model of volunteer community health workers (CHWs is a common approach to serving the poor communities in developing countries. BRAC, a large NGO in Bangladesh, is a pioneer in this area, has been using female CHWs as core workers in its community-based health programs since 1977. After 25 years of implementing of the CHW model in rural areas, BRAC has begun using female CHWs in urban slums through a community-based maternal health intervention. However, BRAC experiences high dropout rates among CHWs suggesting a need to better understand the impact of their dropout which would help to reduce dropout and increase program sustainability. The main objective of the study was to estimate impact of dropout of volunteer CHWs from both BRAC and community perspectives. Also, we estimated cost of possible strategies to reduce dropout and compared whether these costs were more or less than the costs borne by BRAC and the community. Methods We used the ‘ingredient approach’ to estimate the cost of recruiting and training of CHWs and the so-called ‘friction cost approach’ to estimate the cost of replacement of CHWs after adapting. Finally, we estimated forgone services in the community due to CHW dropout applying the concept of the friction period. Results In 2009, average cost per regular CHW was US$ 59.28 which was US$ 60.04 for an ad-hoc CHW if a CHW participated a three-week basic training, a one-day refresher training, one incentive day and worked for a month in the community after recruitment. One month absence of a CHW with standard performance in the community meant substantial forgone health services like health education, antenatal visits, deliveries, referrals of complicated cases, and distribution of drugs and health commodities. However, with an additional investment of US$ 121 yearly per CHW BRAC could save another US$ 60 invested an ad-hoc CHW plus forgone services in the community. Conclusion Although CHWs

    Purpose To assist in determining barriers to an oncology career incorporating cancer prevention, the American Society of Clinical Oncology (ASCO) Cancer Prevention Workforce Pipeline Work Group sponsored surveys of training program directors and oncology fellows. Methods Separate surveys with parallel questions were administered to training program directors at their fall 2013 retreat and to oncology fellows as part of their February 2014 in-training examination survey. Forty-seven (67%) of 70 training directors and 1,306 (80%) of 1,634 oncology fellows taking the in-training examination survey answered questions. Results Training directors estimated that ≤ 10% of fellows starting an academic career or entering private practice would have a career focus in cancer prevention. Only 15% of fellows indicated they would likely be interested in cancer prevention as a career focus, although only 12% thought prevention was unimportant relative to treatment. Top fellow-listed barriers to an academic career were difficulty in obtaining funding and lower compensation. Additional barriers to an academic career with a prevention focus included unclear career model, lack of clinical mentors, lack of clinical training opportunities, and concerns about reimbursement. Conclusion Reluctance to incorporate cancer prevention into an oncology career seems to stem from lack of mentors and exposure during training, unclear career path, and uncertainty regarding reimbursement. Suggested approaches to begin to remedy this problem include: 1) more ASCO-led and other prevention educational resources for fellows, training directors, and practicing oncologists; 2) an increase in funded training and clinical research opportunities, including reintroduction of the R25T award; 3) an increase in the prevention content of accrediting examinations for clinical oncologists; and 4) interaction with policymakers to broaden the scope and depth of reimbursement for prevention counseling and

    Full Text Available A evasão escolar no ensino superior é um fenômeno complexo e, portanto, não pode ser analisado fora de um contexto histórico mais amplo, pois é reflexo da realidade de níveis anteriores de ensino, influenciando de diversas maneiras para o abandono de um curso superior. A avaliação institucional permeia todos esses processos e pode auxiliar na identificação dos sinais da evasão, reduzindo-a ou mesmo evitando-a. Este artigo analisa a produção teórica que aborda a evasão e a sua relação com a avaliação a partir da Biblioteca Digital de Teses e Dissertações (BDTD entre 2008-2009. A metodologia baseia-se na pesquisa bibliográfica, denominada estado da arte ou estado do conhecimento, que contribui para a discussão e o mapeamento da produção acadêmica tanto em termos de análise qualitativa, quanto quantitativa. Vimos que a relação entre evasão e avaliação ainda é pouco estudada, sendo mais restrita ainda que a reflexão sobre a evasão no ensino superior.The dropout rate of undergraduate students is a complex phenomenon that cannot be analyzed without taking into consideration a wider historical context for it is a consequence of previous educational levels, which influence in several different ways higher education dropout rates.

    Motivation to change has been proposed as a prerequisite for behavioral change, although empirical results are contradictory. Traumatic experiences are frequently found amongst patients in alcohol treatment, but this has not been systematically studied in terms of effects on treatment outcomes. This study aimed to clarify whether individual Trauma Load explains some of the inconsistencies between motivation to change and behavioral change. Over the course of two months in 2009, 55 patients admitted to an alcohol detoxification unit of a psychiatric hospital were enrolled in this study. At treatment entry, we assessed lifetime Trauma Load and motivation to change. Mode of discharge was taken from patient files following therapy. We tested whether Trauma Load moderates the effect of motivation to change on dropout from alcohol detoxification using multivariate methods. 55.4% dropped out of detoxification treatment, while 44.6% completed the treatment. Age, gender and days in treatment did not differ between completers and dropouts. Patients who dropped out reported more traumatic event types on average than completers. Treatment completers had higher scores in the URICA subscale Maintenance. Multivariate methods confirmed the moderator effect of Trauma Load: among participants with high Trauma Load, treatment completion was related to higher Maintenance scores at treatment entry; this was not true among patients with low Trauma Load. We found evidence that the effect of motivation to change on detoxification treatment completion is moderated by Trauma Load: among patients with low Trauma Load, motivation to change is not relevant for treatment completion; among highly burdened patients, however, who a priori have a greater risk of dropping out, a high motivation to change might make the difference. This finding justifies targeted and specific interventions for highly burdened alcohol patients to increase their motivation to change.

    This final report on the NKS/RAK-1.2 summarizes the main features of the PIFRAP PC-program and its intended implementation. Regardless of the preferred technical approach to LOCA frequency estimation, the analysis approach must include recognition of the following technical issues: (a) Degradation and failure mechanisms potentially affecting piping systems within the reactor coolant pressure boundary (RCPB) and the potential consequences; (b) In-service inspection practices and how they influence piping reliability; and (c) The service experience with piping systems. The report consists of six sections and one appendix. A Nordic perspective on LOCA and nuclear safety is given. It includes summaries of results from research in material sciences and current regulatory philosophies regarding piping reliability. A summary of the LOCA concept is applied in Nordic PSA studies. It includes a discussion on deterministic and probabilistic views on LOCA. The R and D on piping reliability by SKI and the PIFRAP model is summarized. Next, Section 6 presents conclusion and recommendations. Finally, Appendix A contains a list of abbreviations and acronyms, together with a glossary of technical terms. (EG) 16 refs.

    2001-09-01

    The aim of this study was to document, using consensus methodology, current practice for prevention of generalized reactions to contrast media, to identify areas where there is disagreement or confusion and to draw up guidelines for reducing the risk of generalized contrast media reactions based on the survey and a review of the literature. A document with 165 questions was mailed to 202 members of the European Society of Urogenital Radiology. The questions covered risk factors and prophylactic measures for generalized contrast media reactions. Sixty-eight members (34%) responded. The majority indicated that a history of moderate and severe reaction(s) to contrast media and asthma are important risk factors. The survey also indicated that patients with risk factors should receive non-ionic contrast media. In patients at high risk of reaction, if the examination is deemed absolutely necessary, a resuscitation team should be available at the time of the procedure. The majority (91%) used corticosteroid prophylaxis given at least 11 h before contrast medium to patients at increased risk of reaction. The frequency of the dosage varied from one to three times. Fifty-five percent also use antihistamine Hl, mainly administered orally and once. Antihistamine H2 and ephedrine are rarely used. All essential drugs are available on the emergency resuscitation trolley. Patients with risk factors are observed up to 30 min by 48% and up to 60 min by 43% of the responders. Prophylactic measures are not taken before extravascular use of contrast media. Prophylactic drugs are given to patients with a history of moderate or severe generalized reaction to contrast media. In patients with asthma, opinion is divided with only half of the responders giving prophylactic drugs. Aspirin, {beta}-blockers, interleukin-2 and non-steroid anti-inflammatory drugs are not considered risk factors and therefore are not stopped before injection of contrast media. The survey showed some variability in

  19. LED Current Balance Using a Variable Voltage Regulator with Low Dropout vDS Control

    Directory of Open Access Journals (Sweden)

    Hung-I Hsieh

    2017-02-01

    Full Text Available A cost-effective light-emitting diode (LED current balance strategy using a variable voltage regulator (VVR with low dropout vDS control is proposed. This can regulate the multiple metal-oxide-semiconductor field-effect transistors (MOSFETs of the linear current regulators (LCR, maintaining low dropout vDS on the flat vGS-characteristic curves and making all drain currents almost the same. Simple group LCRs respectively loaded with a string LED are employed to implement the theme. The voltage VVdc from a VVR is synthesized by a string LED voltage NvD, source voltage vR, and a specified low dropout vDS = VQ. The VVdc updates instantly, through the control loop of the master LCR, which means that all slave MOSFETs have almost the same biases on their flat vGS-characteristic curves. This leads to all of the string LED currents being equal to each other, producing an almost even luminance. An experimental setup with microchip control is built to verify the estimations. Experimental results show that the luminance of all of the string LEDs are almost equal to one another, with a maximum deviation below 1% during a wide dimming range, while keeping all vDS of the MOSFETs at a low dropout voltage, as expected.

    We present the first in situ observations of heavy ion dropouts within the slow solar wind, observed for select elements ranging from helium to iron. For iron, these dropouts manifest themselves as depletions of the Fe/H ratio by factors up to {approx}25. The events often exhibit mass-dependent fractionation and are contained in slow, unsteady wind found within a few days from known stream interfaces. We propose that such dropouts are evidence of gravitational settling within large coronal loops, which later undergo interchange reconnection and become source regions of slow, unsteady wind. Previously, spectroscopic studies by Raymond et al. in 1997 (and later Feldman et al. in 1999) have yielded strong evidence for gravitational settling within these loops. However, their expected in situ signature plasma with heavy elements fractionated by mass was not observed prior to this study. Using data from the SWICS instrument on board the Advanced Composition Explorer (ACE), we investigate the composition of the solar wind within these dropouts and explore long term trends over most of a solar cycle.

  13. Joint partially linear model for longitudinal data with informative drop-outs.

    Kim, Sehee; Zeng, Donglin; Taylor, Jeremy M G

    2017-03-01

    In biomedical research, a steep rise or decline in longitudinal biomarkers may indicate latent disease progression, which may subsequently cause patients to drop out of the study. Ignoring the informative drop-out can cause bias in estimation of the longitudinal model. In such cases, a full parametric specification may be insufficient to capture the complicated pattern of the longitudinal biomarkers. For these types of longitudinal data with the issue of informative drop-outs, we develop a joint partially linear model, with an aim to find the trajectory of the longitudinal biomarker. Specifically, an arbitrary function of time along with linear fixed and random covariate effects is proposed in the model for the biomarker, while a flexible semiparametric transformation model is used to describe the drop-out mechanism. Advantages of this semiparametric joint modeling approach are the following: 1) it provides an easier interpretation, compared to standard nonparametric regression models, and 2) it is a natural way to control for common (observable and unobservable) prognostic factors that may affect both the longitudinal trajectory and the drop-out process. We describe a sieve maximum likelihood estimation procedure using the EM algorithm, where the Akaike information criterion (AIC) and Bayesian information criterion (BIC) are considered to select the number of knots. We show that the proposed estimators achieve desirable asymptotic properties through empirical process theory. The proposed methods are evaluated by simulation studies and applied to prostate cancer data.

    The elemental abundances of heavy ions (masses larger than He) in the solar wind provide information about physical processes occurring in the corona. Additionally, the charge state distributions of these heavy ions are sensitive to the temperature profiles of their respective source regions in the corona. Heavy ion dropouts are a relatively new class of solar wind events identified by both elemental and ionic charge state distributions. We have shown that their origins lie in large, closed coronal loops where processes such as gravitational settling dominate and can cause a mass-dependent fractionation pattern. In this study we consider and attempt to answer three fundamental questions concerning heavy ion dropouts: (1) 'where are the source loops located in the large-scale corona?'; (2) 'how does the interplay between coronal processes influence the end elemental abundances?'; and (3) 'what are the most probable release mechanisms'? We begin by analyzing the temporal and spatial variability of heavy ion dropouts and their correlation with heliospheric plasma and magnetic structures. Next we investigate the ordering of the elements inside dropouts with respect to mass, ionic charge state, and first ionization potential. Finally, we discuss these results in the context of the prevailing solar wind theories and the processes they posit that may be responsible for the release of coronal plasma into interplanetary space.

    The aim of this study was to assess drop-out rates and associated reasons among patients at the Iranian National Center for Addiction Studies (INCAS) clinic. In a one-year period (April 2014 to March 2015), all patients with drug dependence who had been referred for treatment and attended for a first assessment were included in this study (N=242). Those who received treatment were followed until March 2016. Survival analysis showed that 70.2% had dropped out from treatment. Log rank test showed that treatment drop-out rates differed between the different approaches used (P Drop-out rates within the first three months was 62% (SE= 0.05) and 82.4% (SE=0.03) for opioids and stimulants dependence, respectively. Analyses were performed using SPSS (Version 21.0) and STATA software, (version 13.0). From the patients' perspective, motivational inconsistencies were considered as the main reason for not starting or leaving treatment. The findings of this study could give service providers a better grasp of drop-out rates and the associated reasons.

    The evaluation of psychiatric interventions results should be multidimensional, including clinical and social variables, such as individual experience of the mentally ill. The patient satisfaction with care has been recognized as an important variable, despite not being the main objective of the service or of the psychiatrist. However, if the user's perspective is not included, there's a risk of bias by the perception of the heath care providers. In this study, our aim was to understand if the abandonment of treatment (drop-out) represents an improvement or worsening of subjective well-being of patients and / or dissatisfaction with the services received, as well as to find predictors of drop-out. Identification of drop-outs in a 2-year cohort of patients who had initial psychiatric consultations in the Psychiatric Unit at Centro Hospitalar do Médio Ave - Unidade de Famalicão (Local Mental Health Service). We identified 512 patients who had a first psychiatric consultation, 57 of which unilaterally abandoned the treatment for at least six months, without making any contacts in order to reschedule the appointment during this period. Of these only 38 completed the assessment (telephone response to a semi-structured questionnaire). Three predictive factors for the drop-out were found: age, education and diagnosis. The reasons for treatment abandonment focused mainly in forgetfulness and dissatisfaction, the last one involving doctor-patient relationship issues. These results should be a starting point for assessing and improving care.

    In observational studies, interest mainly lies in estimation of the population-level relationship between the explanatory variables and dependent variables, and the estimation is often undertaken using a sample of longitudinal data. In some situations, the longitudinal data sample features biases and loss of estimation efficiency due to non-random drop-out. However, inclusion of population-level information can increase estimation efficiency. In this paper we propose an empirical likelihood-based method to incorporate population-level information in a longitudinal study with drop-out. The population-level information is incorporated via constraints on functions of the parameters, and non-random drop-out bias is corrected by using a weighted generalized estimating equations method. We provide a three-step estimation procedure that makes computation easier. Some commonly used methods are compared in simulation studies, which demonstrate that our proposed method can correct the non-random drop-out bias and increase the estimation efficiency, especially for small sample size or when the missing proportion is high. In some situations, the efficiency improvement is substantial. Finally, we apply this method to an Alzheimer's disease study.

    This paper investigates the conditions for producing rapid variations of solar energetic particle (SEP) intensity commonly known as 'dropouts'. In particular, we use numerical model simulations based on solving the focused transport equation in the three-dimensional Parker interplanetary magnetic field to put constraints on the properties of particle transport coefficients in both directions perpendicular and parallel to the magnetic field. Our calculations of the temporal intensity profile of 0.5 and 5 MeV protons at the Earth show that the perpendicular diffusion must be small while the parallel mean free path is long in order to reproduce the phenomenon of SEP dropouts. When the parallel mean free path is a fraction of 1 AU and the observer is located at 1 AU, the perpendicular to parallel diffusion ratio must be below 10{sup –5} if we want to see the particle flux dropping by at least several times within 3 hr. When the observer is located at a larger solar radial distance, the perpendicular to parallel diffusion ratio for reproducing the dropouts should be even lower than that in the case of 1 AU distance. A shorter parallel mean free path or a larger radial distance from the source to observer will cause the particles to arrive later, making the effects of perpendicular diffusion more prominent and SEP dropouts disappear. All of these effects require the magnetic turbulence that resonates with the particles to be low everywhere in the inner heliosphere.

    Odontomas are the most common odontogenic tumours. They are considered as hamartomas - a local tissue malformation without autonomous growth potential - and are non-neoplastic. Clinically and histopathologically, compound and complex odontomas can be differentiated. Compound odontomas consist of a varying number of tooth-like structures and histology show dental tissues in an orderly pattern. Most often compound odontomas are diagnosed in young patients in the anterior maxilla. Patients are rarely complaining of symptoms and they are usually diagnosed during routine radiographic examinations or due to late eruption of permanent or persistence of deciduous teeth. The following case report presents a disturbed eruption of a lateral right incisor of the maxilla in a 8-year old female patient. Clinical, radiological and histopathological characteristics of this lesion will be discussed as well as therapy and follow-up.

    This report presents a preliminary study investigating the effects of large-volume liposuction on the parameters that determine type 2 diabetes. The study enrolled 31 patients with a body mass index (BMI) exceeding 30 kg/m(2) over a 1-year period. All the liposuction procedures were performed with the patient under local anesthesia using ketamine/valium sedation. Pre- and postoperative blood pressure, fasting glucose, glycosylated hemoglobin (HbA1C), weight, and BMI were evaluated for 16 of the 30 patients who returned for a follow-up visit 3 to 12 months postoperatively. The average aspirate was 8,455 ml without dermolipectomy and 5,795 ml with dermolipectomy. The data reveal a trend of improvement in blood sugar levels associated with weight loss that helps the patients. The average blood sugar level dropped 18% in our return patients, and the average weight loss was 9.2%. The average drop in BMI was 6.2%, and HbA1C showed a decrease of 2.3%. The patients with the best weight loss had the best reduction in blood sugar level and blood pressure. No transfers to the hospital and no thromboebolism occurred for any of the 31 patients. One dehiscence, two wound infections, and three seromas were reported. The authors hypothesize that large-volume liposuction in their series may have motivated some to diet, which could be explored in a larger series with control groups. Liposuction alone did not improve obesity but helped to motivate some of the patients to lose weight. These patients had the best results.

    Full Text Available Background: Older adults are at risk of fallingeach year. Fall injuries results in many health care expenses anddisabilities, yet non-western countries lack the infra-structure andresources for prevention programs. Balance exercises have beenfound to be a cost effective evidence-based intervention in treatingand preventing falls among older adults in western countries.Purpose: The aim of this report was to show that lumbar stabilizationexercises are not only a beneficial addition to a balanceprogram for the prevention and treatment of falls in older adults,but to demonstrate that these exercise can more rapidly improve thefunctional status of older adults, limiting healthcare costs.Case description: Two high functional older adults with a historyof falls presented with poor balance and fear of falling. Both patientsreceived the same balance exercise regime however lumbar stabilization exercises were added to one of the patient’s exerciseprograms. Gait speed, lower extremity strength and balance were assessed with the Balance Evaluation systems test (BESTest,figure-of-eight, four-step-square (FSST, five-time-sit-to-stand tests (5TSTS after two weeks and four weeks of treatment.Outcomes. All the outcome measures showed statistically significant improvements. Greater improvements in vertical stabilitylimits (14%, gait speed (9%, stability during gait (20% and five-time-sit-to-stand test were seen with the addition of lumbarstabilization exercises.Discussion. The addition of lumbar stabilization exercises during balance training is of value to improve gait speed, balancetesting scores in stability in gait and vertical stability limits.

  16. Regular Recycling of Wood Ash to Prevent Waste Production (RecAsh). Technical Final Report

    At present, the extraction of harvest residues is predicted to increase in Sweden and Finland. As an effect of the intensified harvesting, the export of nutrients and acid buffering substances from the growth site is also increased. Wood ash could be used to compensate forest soils for such losses. Most wood fuel ash is today often deposited in landfills. If the wood ash is recycled, wood energy is produced without any significant waste production. Ash recycling would therefore contribute to decreasing the production of waste, and to maintaining the chemical quality of forest waters and biological productivity of forest soils in the long term. The project has developed, analysed and demonstrated two regular ash-recycling systems. It has also distributed knowledge gathered about motives for ash recycling as well as technical and administrative solutions through a range of media (handbooks, workshops, field demonstrations, reports, web page and information videos). Hopefully, the project will contribute to decreasing waste problems related to bio-energy production in the EU at large. The project has been organised as a separate structure at the beneficiary and divided in four geographically defined subprojects, one in Finland and three in Sweden (Central Sweden, Northern Sweden, and South-western Sweden). The work in each subproject has been lead by a subproject leader. Each subproject has organised a regional reference group. A project steering committee has been established consisting of senior officials from all concerned partners. The project had nine main tasks with the following main expected deliverables and output: 1. Development of two complete full-scale ash-recycling systems; 2. Production of handbooks of the ash recycling system; 3. Ash classification study to support national actions for recommendations; 4. Organise regional demonstrations of various technical options for ash treatment and spreading; 5. Organise national seminars and demonstrations of

    Family services within Veterans Affairs Medical Centers fulfill an important role in addressing relationship distress among Veterans, which is highly prevalent and comorbid with psychopathology. However, even for evidence-based couple therapies, effectiveness is weaker compared to controlled studies, maybe because many Veteran couples drop out early and do not reach the "active" treatment stage after the 3-4 session assessment. In order to improve outcomes, it is critical to identify couples at high risk for early dropout, and understand whether couples may benefit from the assessment as an intervention. The current study examined (a) demographics, treatment delivery mode, relationship satisfaction, and psychological symptoms as predictors of dropout during and immediately following the assessment phase, and (b) changes in relationship satisfaction during assessment. 174 couples completed questionnaires during routine intake procedures. The main analyses focused on 140 male Veterans and their female civilian partners; 36.43% dropped out during the assessment phase and 24.74% of the remaining couples immediately following the first treatment session. More severe depressive symptoms in non-Veteran partners were associated with dropout during assessment. Relationship satisfaction improved significantly during the assessment phase for couples who did not drop out, with larger gains for non-Veteran partners. No demographics or treatment delivery mode were associated with dropout. Although more research is needed on engaging couples at risk for early dropout and maximizing early benefits, the findings suggest that clinicians should attend to the civilian partner's and Veteran's depressive symptoms at intake and consider the assessment part of active treatment. © 2017 Family Process Institute.

    Previous studies have shown drop-out from cardiac rehabilitation (CR) to have prognostic influence on morbidity and mortality among patients with ischaemic heart disease (IHD). We aimed to identify and clarify patients' reasons for non-attendance and drop-out from CR. A total of 872 consecutive patients with acute myocardial infarction and/or after percutaneous coronary intervention or coronary artery bypass surgery were asked by conventional mail to fill in a self-completion questionnaire on their choice of post-hospital CR and their reasons for drop-out or for non-attendance. Age, employment and marital status had a statistically significant influence on the overall course of CR. Younger age, affiliation with the labour market and living alone were related to a higher drop-out from CR in univariate analysis. We found no evidence of a gender difference among the patients who withdrew. Lack of time was stated as the prevailing reason for non-attendance and withdrawal from CR programmes among employed patients and in people aged 65 years or younger. Patients above 75 years of age asked for additional differentiation of exercise levels; currently two levels are offered. Or they found CR meaningless given their physical condition or their overall life situation. In patients with IHD, age, marital status and employment status play a role in the patient's attendance or drop out from CR. Different physical conditions, lack of time, too great a distance from residence to hospital, transport problems and lack of understanding of the benefits of CR explain why patients refuse to participate in or drop-out from CR. supported by grant from The Danish Ministry of Health. not relevant.

    Respiratory abnormalities are often overlooked; however, because of their potential comorbidity, they must be analyzed to determine the most effective treatment for patients with Parkinson disease (PD). Among various theories on respiratory abnormalities in PD, "upper airway obstruction" and "restrictive respiratory disorders" are 2 of the most accepted etiologies; both appear to be related to basal ganglia dysfunction. Complex vocal cord muscle dysfunction contributes to stridor, which can be a manifestation of nigrostriatal dopaminergic dysfunction. Stridor is a lethal form of upper airway obstruction in PD patients; its most frequent causes are bilateral vocal cord palsy, laryngeal spasms, and dystonia of the supra-laryngeal muscle. Several previous studies have suggested that levodopa administration induces a significant improvement of both lung function and symptoms of parkinsonian syndrome. We reported a 77-year-old gentleman PD patient admitted for acute levodopa-responsive stridor resulting from bilateral vocal cord palsy. Dopaminergic therapy prevented the need for subsequent endotracheal intubation and tracheostomy treatment. It is vital to understand that complex vocal cord muscle dysfunction may be related to nigrostriatal dopaminergic dysfunction in PD patients. The strategy of levodopa up-titration should be considered an option because it may be beneficial in relieving both stridor and parkinsonian syndrome, and in preventing respiratory failure.

    This study was conducted with the aim of showing the effects of Pycnogenol on controlling jet-lag symptoms. Oral Pycnogenol, 50 mg tablets 3 times/die, for 7 days starting 2 days prior to the flight was used. The study was divided into two separate parts. In study 1 the most common complaints of patients with jet-lag were evaluated with a rating scale consisting in of a scoring system. In study 2 a brain CT scan was performed after the flight in order to assess minimal brain edema (MBE) in association with typical signs and symptoms, observed in previous published flight studies. Study one included 38 subjects treated with Pycnogenol and 30 controls. The symptomatic jet-lag related total score was significantly lower (indicating a lower level of jet-lag) in the Pycnogenol group. The average duration of any jet lag symptom following the flight was significantly reduced from 39.3 (SD=0.8) hours in controls to an average of 18.2 (SD=3.3) hours in the Pycnogenol group (PPycnogenol and 31 controls. The main observation was the brain CT scan performed within 28 hours after the end of the flight. The difference between the Pycnogenol and the control groups was statistically significant (PPycnogenol group. A number of spontaneously reported symptoms was also scored and there was a statistically significant difference (PPycnogenol and control groups. In conlusion, Pycnogenol was useful to control jet-lag and minimal brain edema.

    2016-02-01

    Full Text Available Introduction: From the beginning of the first year of medical studies, increased psychological stress and elevated burnout prevalence rates can be registered compared to sample populations. Characterized by learning “on an equal footing”, the principle of peer-assisted learning (PAL is widely used in medical education. This report aims to showcase the development and evaluation of peer-led stress prevention seminars for first year medical students after one year of implementation.Project description: With each of the three sessions lasting 90 min., the stress prevention seminars took place in small groups (6-10 students in the period from November 2013 to January 2014 and from November 2014 to December 2014 at the Medical Faculty of Heidelberg. Led by trained peers, the seminar content ranged from psycho-educational elements, i.e. time management strategy development and test anxiety assistance, to relaxation techniques. All seminar sessions were evaluated via questionnaire. All questions were answered on a Likert scale ranging from 1 to 7 (1=strongly agree; 7=strongly disagree.Results: 75 students consented to participate in seminars (65% female; aged 20.5±3.3 years. The series of seminars was averagely given the school grade of 1.2±0.4 (1=very good to 6=unsatisfactory in WS 2013/14 and 1.5±0.5 in the following year and the peer tutors’ competence was evaluated as very high (1.4 to 1.5 approval rate on the Likert scale.Discussion: The seminar sessions’ importance to the students is underlined by their very positive evaluations. This offer seems to have benefited students especially during the demanding transitional phase at the start of their studies. Both the implementation of the preventive measure at an early stage as well as the use of PAL seem to have proven effective.Conclusion: PAL seems to be effective in the field of stress prevention. However, specific efficacy studies are still lacking.

    The quality of reporting in congress abstracts is likely to influence clinical decision-making. The quality of reporting in sports injury prevention abstracts has increased over the last 3 years, as did the number of randomised controlled trials (RCT). 154 abstracts from the 2005 and 186 abstracts from 2008 World Conferences on Sports Injury Prevention in Norway were analysed. Scores of 17 Consolidated Standards of Reporting Trials (CONSORT) criteria for RCT, or 22 Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) criteria for observational studies were determined. Improvement in reporting was evident in RCT (CONSORT score 5.8±0.9 vs 8.6±2.9, p=0.001, CI -4.29 to -1.43) as well as for observational studies (STROBE score 7.9±1.6 vs 9.9±1.7, pSports Injury Prevention remained unchanged, an improvement in reporting of abstracts was evident from 2005 to 2008, as determined by CONSORT/STROBE criteria. However, substantial and comprehensive use of the CONSORT and STROBE criteria might further increase the quality of reporting of sports injury conference abstracts in the future.

    Long tolerated as a rite of passage into adulthood, bullying is now recognized as a major and preventable public health problem. The consequences of bullying-for those who are bullied, the perpetrators of bullying, and the witnesses-include poor physical health, anxiety, depression, increased risk for suicide, poor school performance, and future delinquent and aggressive behavior. Despite ongoing efforts to address bullying at the law, policy, and programmatic levels, there is still much to learn about the consequences of bullying and the effectiveness of various responses. In 2016, the National Academies of Sciences, Engineering, and Medicine published a report entitled Preventing Bullying Through Science, Policy and Practice, which examined the evidence on bullying, its impact, and responses to date. This article summarizes the report's key findings and recommendations related to bullying prevention.

    The primary source of funding for the United States transportation system is derived from motor fuel and other highway use taxes. Loss of revenue attributed to fuel-tax evasion has been assessed to be somewhere between 1 billion and 3 billion per year. Any solution that addresses this problem needs to include not only the tax-collection agencies and auditors, but also the carriers transporting oil products and the carriers customers. This report presents a system developed by the Oak Ridge National Laboratory (ORNL) for the Federal Highway Administration which has the potential to reduce or eliminate many fuel-tax evasion schemes. The solution balances the needs of tax-auditors and those of the fuel-hauling companies and their customers. The system has three main components. The on-board subsystem combined sensors, tracking and communication devices, and software (the on-board Evidential Reasoning System, or obERS) to detect, monitor, and geo-locate the transfer of fuel among different locations. The back office sub-system (boERS) used self-learning algorithms to determine the legitimacy of the fuel loading and offloading (important for tax auditors) and detect potential illicit operations such as fuel theft (important for carriers and their customers, and may justify the deployment costs). The third sub-system, the Fuel Distribution and Auditing System or FDAS, is a centralized database, which together with a user interface allows tax auditors to query the data submitted by the fuel-hauling companies and correlate different parameters to quickly identify any anomalies. Industry partners included Barger Transport of Weber City, Virginia (fleet); Air-Weigh, of Eugene, Oregon (and their wires and harnesses); Liquid Bulk Tank (LBT) of Omaha, Nebraska (three five-compartment trailers); and Innovative Software Engineering (ISE) of Coralville, Iowa(on-board telematics device and back-office system).

Loss of revenue attributed to fuel-tax evasion has been assessed to be somewhere between 1 billion and 3 billion per year. Any solution that addresses this problem needs to include not only the tax-collection agencies and auditors, but also the carriers transporting oil products and the carriers customers. This report presents a system developed by the Oak Ridge National Laboratory (ORNL) for the Federal Highway Administration which has the potential to reduce or eliminate many fuel-tax evasion schemes. The solution balances the needs of tax-auditors and those of the fuel-hauling companies and their customers. The system has three main components. The on-board subsystem combined sensors, tracking and communication devices, and software (the on-board Evidential Reasoning System, or obERS) to detect, monitor, and geo-locate the transfer of fuel among different locations. The back office sub-system (boERS) used self-learning algorithms to determine the legitimacy of the fuel loading and offloading (important for tax auditors) and detect potential illicit operations such as fuel theft (important for carriers and their customers, and may justify the deployment costs). The third sub-system, the Fuel Distribution and Auditing System or FDAS, is a centralized database, which together with a user interface allows tax auditors to query the data submitted by the fuel-hauling companies and correlate different parameters to quickly identify any anomalies. Industry partners included Barger Transport of Weber City, Virginia (fleet); Air-Weigh, of Eugene, Oregon (and their wires and harnesses); Liquid Bulk Tank (LBT) of Omaha, Nebraska (three five-compartment trailers); and Innovative Software Engineering (ISE) of Coralville, Iowa(on-board telematics device and back-office system). ORNL conducted a pilot test with the three instrumented vehicles

    transfer learning being a promising approach, it is still an open question how to adapt the model learned from the source dataset to the target dataset. One big challenge is to prevent the impact of category bias on classification performance. Dataset bias exists when two images from the same category...

    In this study we present a clinical application of the STEPPS model in an Italian sample of severely affected patients with borderline personality disorder (BPD) or personality disorder (PD) with prominent borderline features in comorbidity with a mood disorder. The aims of this work are: 1) to confirm our preliminary results in a larger sample and at a 12-month follow-up, and 2) to identify predictors of drop-out vs completion of STEPPS in order to understand which characteristics of patients make them suitable or not for this treatment. The sample is composed of 32 subjects recruited from a population of inpatients of the Mood Disorders Center, Department of Clinical Neurosciences, Hospital San Raffaele-Turro, Milan. To confirm STEPPS efficacy at 12-month follow-up, we selected the following outcome criteria: reduction in the number of hospitalizations related to self-harm acts; reduction in the number of suicidal attempts; reduction of perceived emotional intensity levels; changes in cognitive filter scores; changes in the scores on self-report questionnaires. To identify predictors of drop-out vs completion, we analysed the following variables: demographic features (sex, marital status, school level achieved, and job status); Axis-I diagnosis; Axis-II categorical and dimensional diagnosis; and personality features. Seventeen (53%) subjects completed the treatment successfully. The drop-out rate was 47%. Patients who completed the program show a significant decrease in the number of hospitalizations, both at the end of the treatment and at 12-month follow-up. Friedman ANOVA test shows a significant decrease in suicidal attempts during and after STEPPS, and at 12-month follow-up. Analysis of drop-outs showed no significant differences with regard to sex, marital status, school level and job status between the two groups. Axis-I and Axis-II categorical diagnoses did not discriminate between the two groups. Those patients who dropped differ significantly from

    Full Text Available We report three cases of a rare pattern of mid-thoracic spine injuries after horse racing falls and discuss possible causative factors and prevention measurements to reduce injury rates in professional riding and racing. Three patients, 2 male and 1 female with a mean age of 28 years old, underwent surgical treatment for mid-thoracic fractures after professional equestrian activities. The ASIA scale was E in one patient, B in the other one and A in the third. Multilevel posterior fusion was used in two patients and somatectomy plus fusion in the other. Follow up evaluation included changing of the ASIA scale, functional outcome and participation in equestrian activities. One patient fully recovered after surgery. Two patients remained paraplegic despite early surgical treatment and prolonged rehabilitation therapy. All patients had ended their professional equestrian career. This report analyzes possible mechanisms of injury and the pattern of mid-thoracic spine fractures after professional horse riding injuries. Despite skill improvements and continued safety education for horse riding, prophylactic measures for both the head and the spine should be refined. According to our study, additional mid-thoracic spinal protection should be added.

    Full Text Available Recent research in medical education suggests that program specific admission testing could have a protective effect against early dropout. Little is known about the effect of program specific admission testing on dropout in other areas of higher education. The aim of this paper was to examine if admission strategy was also independently associated with dropout for sports science students in a university setting. The study design was a prospective cohort study with a 2 year follow-up. The population was 449 sports science students admitted to a university in the years 2002-2007. The analysis used was multivariate logistic regression and the predictors examined were: admission group (grade-based or admission tested as well as educational and socio-demographic variables. The outcome was dropout within 2 years of study start. Admission testing offered superior protection against dropout compared to grade-based admission. This result may fit with elements of previous dropout theory, student-environment fit theory and perhaps also with self-efficacy theory. Nyere forskning inden for medicinsk uddannelse indikerer at uddannelsesspecifikke optagelsesprøver kan have en beskyttende effekt i forhold til tidligt studiefrafald, men for andre universitetsuddannelser end Medicin synes denne sammenhæng endnu ikke at være blevet grundigt belyst. Formålet med dette studie var derfor at undersøge, om optagelsesprøver også beskyttede mod tidligt frafald blandt idrætsstuderende på universitetet. Studiedesignet var et prospektivt kohortestudie med to års opfølgning. Populationen var 449 idrætsstuderende, som blev optaget på Syddansk Universitet i årene 2002-2007. Data blev analyseret med multivariat logistisk regression, og følgende typer af prædiktorer for frafald blev undersøgt: Optagelseskvote (kvote 1 eller kvote 2 udprøvede, andre uddannelsesrelaterede variable samt udvalgte socio-demografiske variable. Effektmålet var studiestatus (frafaldet

    Poor academic performance is a strong predictor of school dropout. Researchers have tried to disentangle variables influencing academic performance. However, studies on preschool and early care variables are seldom examined when explaining the school dropout process. We reviewed the literature on the relationship between caregiver-child attachment and academic performance, including attachment studies from preschool years, seeking out potential contributions to academic performance and the dropout process. The review was organized according to a model of four main mediating hypotheses: the attachment-teaching hypothesis, the social network hypothesis, the attachment-cooperation hypothesis, and the attachment self-regulation hypothesis. The results of the review are summed up in a model. There is some support for all four hypotheses. The review indicates that attachment and early care contribute substantially to dropout and graduation processes. Mediation effects should be given far more attention in future research.

    obtained from the application of a series of questionnaires that measure different variables used in the TDRI and PDRI analysis. Both indexes have been developed with the purpose of having tools for dropout prediction, which allows to work on its prevention in an anticipated manner. Among the main conclusions obtained in the research, we can point out the relation between academic success, dropout and the PDRI, considering that the 44% of high-risk and very high risk students did not enroll in the second semester.

    The International Agency for Research on Cancer estimates that over half of the new cancer cases and almost two-thirds of the cancer deaths in 2012 occurred in low and middle income countries. To discuss the challenges and opportunities to reducing the burden of cancer worldwide, the Molecular Epidemiology and the Environment and the International Issues in Cancer Special Interest Groups joined forces to hold a session during the 38th Annual Meeting of the American Society of Preventive Oncology (March 2014, Arlington, Virginia). The session highlighted three topics of particular interest to molecular cancer prevention researchers working internationally, specifically: 1) biomarkers in cancer research; 2) environmental exposures and cancer; and 3) molecular pathological epidemiology. A major factor for successful collaboration illuminated during the discussion was the need for strong, committed, and reliable international partners. A key element of establishing such relationships is to thoroughly involve individual international collaborators in the development of the research question; engaged international collaborators are particularly motivated to champion and shepherd the project through all necessary steps, including issues relating to institutional review boards, political sensitivity, laboratory-based assays, and tumor subtyping. Also essential is allotting time for the building, maintaining, and investing in such relationships so that successful international collaborations may take root and bloom. While there are many challenges inherent to international molecular cancer research, the opportunities for furthering the science and prevention of cancer worldwide are great, particularly at this time of increasing cancer incidence and prevalence in low and middle income countries.

    Increasing the adoption and implementation of evidence-based policies and practices is a key strategy for improving public health. Although there is widespread agreement about the importance of implementing evidence-based public health policies and practices, there are gaps between what has been shown to be effective and what is implemented at the state level. The Centers for Disease Control and Prevention (CDC) developed the Prevention Status Reports (PSRs), a performance measurement system, to highlight evidence-based public health policies and practices and catalyze state performance and quality improvement efforts across the nation. CDC selected a set of 10 topics representing some of the most important public health challenges in the nation. Stakeholders, including state health departments and other partners, helped conceptualize the PSRs and informed the development of the PSR framework, which provides an organizational structure for the system. CDC subject matter experts developed criteria for selecting policies and practices, indicators for each policy and practice, and a criteria-based rating system for each indicator. The PSRs were developed for all 50 states and the District of Columbia. The PSRs were developed and serve as a performance measurement system for monitoring the adoption, reach, and implementation fidelity of evidence-based public health policies and practices nationwide. The PSRs include 33 policy and practice indicators across the 10 health topics. They use a simple 3-level rating system-green, yellow, and red-to report the extent to which each state (and the District of Columbia) has implemented the policy or practice in accordance with supporting evidence or expert recommendations. Results from aggregate analyses show positive change or improvement. The PSRs are a unique part of CDC's work to improve the performance and accountability of the public health system, serving as both a monitoring tool and a call to action to improve health
