Kinds of Eligibility Terms modified by Eligibility Selected AbstractsThe clinical effectiveness of length of bed rest for patients recovering from trans-femoral diagnostic cardiac catheterisationINTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 4 2008Sek Ying Chair RN MBA PhD Background, Cardiac catheterisation plays a vital role in the diagnosis and evaluation of cardiac conditions. The goal of management of patients after cardiac catheterisation is to reduce the risk of development of any local or prolonged vascular complications, in particular bleeding and haematoma formation at the puncture site. Bed rest and immobilisation of the affected leg are recommended practices to ensure adequate haemostasis at the femoral arterial puncture site and prevent complications. Objectives, The objective of this review was to present the best available evidence for the optimal length of bed rest after trans-femoral diagnostic cardiac catheterisation. The main outcome of interest was the incidence of bleeding and haematoma formation following varying periods of bed rest. Search strategy, We searched the following databases: CINAHL, Medline, Cochrane Library, Current Contents, EBSCO, Web of Science, Embase, British Nursing Index, Controlled clinical trials database, Google Scholar. Reference lists of relevant articles and conference proceedings were searched. We also contacted key organisations and researchers in the field. Selection criteria, All randomised and quasi-randomised controlled trials that compared the effects of different lengths of bed rest following trans-femoral diagnostic cardiac catheterisation on patient outcomes were considered for inclusion in the review. Data collection and analysis, Eligibility of the trials for inclusion in the review, details of eligible trials and the methodological quality of the trials were assessed independently by two reviewers. Odds ratios (OR) for dichotomous data and a weighted mean difference for continuous data were calculated with 95% confidence intervals (CI). Where synthesis was inappropriate, trials were considered separately. Main results, Eighteen trials involving a total of 4294 participants were included in the review. One trial included three treatment groups. In seven trials among 747 people there was no significant difference in the incidence of bleeding following six or less than 6 h of bed rest (OR 1.47; 95% CI 0.60, 3.64). Likewise, there was no significant difference in the incidence of bleeding following bed rest at other time periods. In eight trials involving 2272 patients there was no significant difference in the incidence of haematoma formation following 6 or less than 6 h of bed rest (OR 0.82; 95% CI 0.59, 1.16). Significantly fewer patients randomised to less than 6 h of bed rest complained of back pain. The odds of developing back pain at 4 (OR 24.60; 95% CI 1.29, 469) and 24 h (OR 2.47; 95% CI 1.16, 5.23) following coronary catheterisation was significantly higher among patients randomised to 6 compared with 3 h of bed rest. Authors' conclusions, There is evidence of no benefit relating to bleeding and haematoma formation in patients who have more than 3 h of bed rest following trans-femoral diagnostic cardiac catheterisation. However, there is evidence of benefit relating to decreased incidence and severity of back pain and cost-effectiveness following 3 h of bed rest. There is suggestive but inconclusive evidence of a benefit from bed rest for 2 h following trans-femoral cardiac catheterisation. Clinicians should consider a balance between avoiding increased risk of haematoma formation following 2,2.5 h of bed rest and circumventing back pain following more than 4 h of bed rest. [source] Effectiveness of brief structured interventions on risk factor modification for patients with coronary heart disease: a systematic reviewINTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 4 2007Ritin Fernandez RN MN (Critical care) PhD Candidate Abstract Background, The physical and psychosocial benefits of participation in cardiac rehabilitation following a coronary event have well been established. Despite these benefits there is strong evidence that participation in traditional cardiac rehabilitation programs remains low. Various models of cardiac rehabilitation have been implemented including the use of brief structured interventions to enable modification of coronary risk factors. Objectives, The objective of this review was to determine the effect of brief structured interventions on risk factor modification in patients with coronary heart disease. Search strategy, A literature search was performed using the following databases MEDLINE (1966,2006), CINAHL (1982,2006), EMBASE (1980,current) and up to the Cochrane Controlled Trials Register (Issue 2, 2006 of Cochrane Library). In addition, the reference lists of relevant trials and conference proceedings were also scrutinised. Company representatives, experts and investigators were contacted to elicit further information. Selection criteria, All randomised and quasi-randomised controlled trials that compared the effects of brief structured interventions on risk factor modification in patients with coronary heart disease were considered for inclusion in the review. Data collection and analysis, Eligibility of the trials for inclusion in the review, details of eligible trials and the methodological quality of the trials were assessed independently by two reviewers. Relative risks for dichotomous data and a weighted mean difference for continuous data were calculated with 95% confidence intervals. Where synthesis was inappropriate, trials were considered separately. Main results, Seventeen trials involving a total of 4725 participants were included in the final review: three trials compared the effects of brief structured interventions on diet modification; seven on smoking cessation; and seven on multiple risk factors. Two trials involving 76 patients compared brief structured intervention versus usual care for dietary modification. Although there was a tendency for more participants in the intervention arm to lose weight at the 12-week follow up and achieve target cholesterol levels at the 6-month follow up, these results were not statistically significant. Only one small trial involving 36 patients compared brief structured intervention and extensive intervention for dietary modification and demonstrated a significant reduction in the percentage of energy obtained from fat and saturated fat intake among participants receiving extensive intervention. However, no difference in fish, fruit and vegetable intake between the groups was evident. Six trials involving 2020 patients compared brief structured intervention versus usual care for smoking cessation. There was no difference in the smoking cessation rates at the 3- and 6-week follow up, however, there was evidence of a benefit of brief structured interventions for smoking cessation at the 3-, 6- and 12-month follow up. In the only trial that and compared brief structured intervention and extensive intervention for smoking cessation in 254 participants there was no clear difference of a likelihood of smoking cessation between the two groups. In the seven trials that compared brief structured intervention and usual care for multiple risk factor modification there was evidence of a benefit of the intervention on behavioural changes such as fat intake, weight loss and consequently on reduction in the body mass index, smoking cessation and physical activity among the participants. The findings concerning the effect on blood pressure, blood glucose levels and the lipid profile, however, remain inconclusive. Conclusions, There is suggestive but inconclusive evidence from the trials of a benefit in the use of brief interventions for risk factor modification in patients with coronary heart disease. This review, however, supports the concept that brief interventions for patients with coronary heart disease can have beneficial effects on risk factor modification and consequently on progression of coronary heart disease. Further trials using larger sample sizes need to be undertaken to demonstrate the benefits of brief structured intervention targeted at the modification of single or multiple risk factors. [source] MISSOURI RIVER FLOOD OF 1993: ROLE OF WOODY CORRIDOR WIDTH IN LEVEE PROTECTION,JOURNAL OF THE AMERICAN WATER RESOURCES ASSOCIATION, Issue 4 2003Stephen B. Allen ABSTRACT. We investigated the relationships between levee damage and woody corridor along a 353-mile segment of the Missouri River in Missouri during the flood of 1993. Results indicated that woody corridors between riverbanks and primary levees played a significant role in the reduction or prevention of flood related damage to levees. Forty-one percent of levee failures in this segment occurred in areas with no woody corridor, while 74 percent and 83 percent of failures occurred where woody corridor widths were less than 300 feet and less than 500 feet, respectively. Median failure lengths with a woody corridor present were 50.3 percent shorter than median failure lengths with no woody corridor present. Levees without failures had significantly wider median woody corridor widths than levees that failed. Eligibility for the Corps of Engineers levee maintenance program was not a significant factor in the reduction of levee damage. Discontinuities in woody corridors played a role in 27.5 percent of the levee failures in the study segment. Smaller segments of the river valley were studied to determine if geomorphic differences influenced variations in the protective value of woody corridors. [source] Review article: the treatment of hepatitis C virus recurrence after liver transplantationALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 2 2007R. R. ARJAL Summary Background Recurrent hepatitis C represents a major challenge for the liver transplant community. Given the potentially significant impact that hepatitis C recurrence has on graft and patient survival, several treatment strategies have been utilized to prevent/slow the progression to hepatitis C-related graft failure. Aim To review the efficacy and applicability of treatment strategies for managing recurrent hepatitis C. Methods Search of MEDLINE (1990 to December 2006) and national meeting abstracts. Search terms included hepatitis C, liver transplantation, treatment, sustained virological response (SVR), and end of treatment virological response. An emphasis was placed on randomized trials. Results The largest study of treatment prior to liver transplantation (n = 124) achieved SVR in 24%. Eight randomized trials (n = 383) examined the efficacy of preemptive therapy with SVR ranging from 0,33%. Eligibility for treatment was low and dose reduction common. Four randomized trials (n = 245; all abstracts) have reported SVR from 33,42% for treating those with histological evidence of recurrent disease. Conclusions Therapies for treating hepatitis C recurrence have limited applicability and tolerability, and they have a low SVR. Based on available results, preemptive therapy is not recommended. Pegylated interferon and ribavirin is currently the preferred choice for treating established recurrence. There is an urgent need for safer and more effective anti-viral therapy in this situation. [source] Recruitment of African American Women to a Walking Program: Eligibility, Ineligibility, and Attrition During Screening,RESEARCH IN NURSING & HEALTH, Issue 3 2006JoEllen Wilbur Abstract The purposes of this study were to identify strategies successful in the recruitment of African American (AA) women to a home-based walking program and to examine factors that contribute to attrition, eligibility, and ineligibility during the recruitment screening protocol. Of the 696 women who contacted the researchers, 281 (40.4%) women enrolled in the study, 227 (32.6%) were lost to attrition, and 188 (27%) were ineligible. Those not enrolled due to attrition during screening or ineligibility reported more family risk for cardiovascular disease (CVD) and lived in neighborhoods with higher poverty. Although our recruitment strategies may have been successful in attracting low-income AA women, we were not as successful in preventing their attrition during the screening protocol, particularly for those living in poorer neighborhoods. © 2006 Wiley Periodicals, Inc.

Kaplan Study Type , Diagnostic (exploratory cohort) Level of Evidence 2b OBJECTIVE To evaluate the Prostate Cancer Prevention Trial (PCPT) risk calculator in a screening cohort of young, racially diverse, high-risk men with a low baseline prostate-specific antigen (PSA) level and enrolled in the Prostate Cancer Risk Assessment Program (PRAP). The PCPT calculator provides an assessment of prostate cancer risk based on age, PSA level, race, previous biopsy, and family history. PATIENTS AND METHODS Eligibility for PRAP includes men aged 35,69 years who are African-American, have a family history of prostate cancer, or have a known BRCA1/2 mutation. PCPT risk scores were determined for PRAP participants, and were compared to observed prostate cancer rates. RESULTS In all, 624 participants were evaluated, including 382 (61.2%) African-American men and 242 (38.7%) men with a family history of prostate cancer; the median (range) age was 49.0 (34.0,69.0) years and the median PSA level 0.9 (0.1,27.2) ng/mL. The PCPT risk score correlated with prostate cancer diagnosis, as the median baseline risk score in patients diagnosed with prostate cancer was 31.3%, vs 14.2% in patients not diagnosed with prostate cancer (P < 0.001). The PCPT calculator similarly stratified the risk of diagnosis of Gleason score ,7 disease, as the median risk score was 36.2% in patients diagnosed with Gleason ,7 prostate cancer vs 15.2% in all other participants (P < 0.001). CONCLUSION The PCPT risk calculator score was found to stratify prostate cancer risk in a cohort of young, primarily African-American men with a low baseline PSA level. These results support further evaluation of this predictive tool for assessing the risk of prostate cancer in high-risk men. [source] The Impact of Internal Auditor Compensation and Role on External Auditors' Planning Judgments and Decisions,CONTEMPORARY ACCOUNTING RESEARCH, Issue 2 2001F. Todd Dezoort Abstract This paper reports the results of an experiment that investigates how external audit planning is affected when internal auditors have incentives and the opportunity to bias their evaluations. Specifically, we draw on attribution theory to examine how internal auditor eligibility for incentive compensation and participation in consulting (i.e., two factors that provide incentives to bias audit evaluations) affect external audit planning. In addition, we examine the effects of incentive compensation and a consulting role across two routine internal audit tasks , an objective tests of controls task and a subjective inventory valuation task , to evaluate whether their effects are contingent upon task subjectivity (i.e., opportunity to bias audit evaluations). Seventy-six external auditors from four Big 5 public accounting firms participated in an experiment that manipulated internal auditor compensation (fixed salary versus incentive compensation), the type of work that the internal auditors routinely perform (primarily auditing versus primarily consulting), and audit task subjectivity (objective tests of controls versus subjective inventory valuation). Our results suggest that the nature of internal auditors' compensation and work affect audit planning recommendations differently. The opportunity to receive incentive compensation results in less reliance on internal auditors' work and greater budgeted audit hours, but only for the subjective task. Although a consulting role decreases perceived internal auditor objectivity, it has a limited effect on planning recommendations. Specifically, consulting has no effect on reliance, and leads to greater budgeted audit hours only when incentive compensation is available. We discuss potential explanations for the results as well as implications for audit research, practice, and regulation. [source] A systematic review of the diagnostic classifications of traumatic dental injuriesDENTAL TRAUMATOLOGY, Issue 2 2006Karla Maria Pugliesi da Costa Feliciano Abstract,,, A systematic review of the literature was undertaken to evaluate the criteria used for the diagnostic classification of traumatic dental injuries from an epidemiological standpoint. The methodology used was that suggested by the Cochrane Collaboration and the National Health Service. A total of 12 electronic bibliographical databases (BBO, BioMed Central, Blackwell Synergy, Cochrane, DARE, EMBASE, HighWire, LILACS, MEDLINE, PubMed Central, SciELO, SciSearch) and the World Wide Web were searched. There was no attempt to specify the strategy in relation to date, study design, or language. The last search was performed in May 2003. Two reviewers screened each record independently for eligibility by examining titles, abstracts, keywords and using a standardized reference form. Disagreements were resolved through consensus. The final study collection consisted of 164 articles, from 1936 to 2003, and the population sample ranged from 38 to 210 500 patients. 54 distinct classification systems were identified. According to the literature, the most frequently used classification system was that of Andreasen (32%); as regards the type of injury, the uncomplicated crown fracture was the most mentioned lesion (88.5%). Evidence supports the fact that there is no suitable system for establishing the diagnosis of the studied injuries that could be applied to epidemiological surveys. [source] Child sexual abuse in the etiology of depression: A systematic review of reviewsDEPRESSION AND ANXIETY, Issue 7 2010Roberto Maniglio Psy.D. Ph.D. Abstract Background: Despite a large amount of research, there is considerable controversy about the role that child sexual abuse plays in the etiology of depression. To prevent interpretative difficulties, mistaken beliefs, or confusion among professionals who turn to this literature for guidance, this article addresses the best available scientific evidence on the topic, by providing a systematic review of the several reviews that have investigated the literature on the issue. Methods: Seven databases were searched, supplemented with hand search of reference lists from retrieved papers. The author and a psychiatrist independently evaluated the eligibility of all studies identified, abstracted data, and assessed study quality. Disagreements were resolved by consensus. Results: Four reviews, including about 60,000 subjects from 160 studies and having no limitations that could invalidate their results, were analyzed. There is evidence that child sexual abuse is a significant, although general and nonspecific, risk factor for depression. The relationship ranges from small-to-medium in magnitude and is moderated by sample source. Additional variables may either act independently to promote depression in people with a history of sexual abuse or interact with such traumatic experience to increase the likelihood of depression in child abuse survivors. Conclusions: For all victims of abuse, programs should focus not only on treating symptoms, but also on reducing additional risk factors. Depressed adults who seek psychiatric treatment should be enquired about early abuse within admission procedures. Depression and Anxiety, 2010. © 2010 Wiley-Liss, Inc. [source] Cognitive performance of male adolescents is lower than controls across psychiatric disorders: a population-based studyACTA PSYCHIATRICA SCANDINAVICA, Issue 6 2004M. Weiser Objective:, Psychiatric patients, as well as humans or experimental animals with brain lesions, often concurrently manifest behavioral deviations and subtle cognitive impairments. This study tested the hypothesis that as a group, adolescents suffering from psychiatric disorders score worse on cognitive tests compared with controls. Method:, As part of the assessment for eligibility to serve in the military, the entire, unselected population of 16,17-year old male Israelis undergo cognitive testing and screening for psychopathology by the Draft Board. We retrieved the cognitive test scores of 19 075 adolescents who were assigned any psychiatric diagnosis, and compared them with the scores of 243 507 adolescents without psychiatric diagnoses. Results:, Mean test scores of cases were significantly poorer then controls for all diagnostic groups, except for eating disorders. Effect sizes ranged from 0.3 to 1.6. Conclusion:, As group, adolescent males with psychiatric disorders manifest at least subtle impairments in cognitive functioning. [source] Estimating the Effects of a Time-Limited Earnings Subsidy for Welfare-LeaversECONOMETRICA, Issue 6 2005David Card In the Self Sufficiency Project (SSP) welfare demonstration, members of a randomly assigned treatment group could receive a subsidy for full-time work. The subsidy was available for 3 years, but only to people who began working full time within 12 months of random assignment. A simple optimizing model suggests that the eligibility rules created an "establishment" incentive to find a job and leave welfare within a year of random assignment, and an "entitlement" incentive to choose work over welfare once eligibility was established. Building on this insight, we develop an econometric model of welfare participation that allows us to separate the two effects and estimate the impact of the earnings subsidy on welfare entry and exit rates among those who achieved eligibility. The combination of the two incentives explains the time profile of the experimental impacts, which peaked 15 months after random assignment and faded relatively quickly. Our findings suggest that about half of the peak impact of SSP was attributable to the establishment incentive. Despite the extra work effort generated by SSP, the program had no lasting impact on wages and little or no long-run effect on welfare participation. [source] Immigration, Migration, and State Redistributive ExpendituresGROWTH AND CHANGE, Issue 1 2001Katherine Hempstead The effect of immigration on state and local budgets is a frequent topic of both political and academic conversations. A controversial issue among scholars is whether or not immigration induces outmigration of low income native born residents, a population movement which would potentially have implications for the jurisdictional distribution of immigration's fiscal impact. It is hypothesized here that if interstate poverty migration occurred, it should cause fiscal spillovers by distributing some of the public sector burden of immigration from immigrant "host" states to neighboring states. This paper uses cross-sectional state data from 1988,1995 to explore the relationship between immigration in neighbor states and state redistributive expenditures. The results suggest that there is a positive relationship between immigration to neighboring states and redistributive expenditures. While most discussion of the fiscal impact of immigration has focused on the effects on host states and localities, the implications of these findings are that there are fiscal spillovers to neighboring states, suggesting that fiscal impacts on host states have been over-estimated and effects on neighboring states have been underestimated. Additionally, the implications of recent welfare reform, which gives states the opportunity to use citizenship as a criterion for program eligibility, are discussed. [source] MTHFR 677C>T and ACE D/I Polymorphisms in Migraine: A Systematic Review and Meta-AnalysisHEADACHE, Issue 4 2010Markus Schürks MD (Headache 2010;50:588-599) Background., Data on the association between the MTHFR 677C>T and ACE D/I polymorphisms and migraine including aura status are conflicting. Objective., The objective of this study is to perform a systematic review and meta-analysis on this topic. Methods., We searched for studies published until March 2009 using electronic databases (MEDLINE, EMBASE, Science Citation Index) and reference lists of studies and reviews on the topic. Assessment for eligibility of studies and extraction of data was performed by 2 independent investigators. For each study we calculated the odds ratios (OR) and 95% confidence intervals (CI) assuming additive, dominant, and recessive genetic models. We then calculated pooled ORs and 95% CIs. Results., Thirteen studies investigated the association between the MTHFR 677C>T polymorphism and migraine. The TT genotype was associated with an increased risk for any migraine, which only appeared for migraine with aura (pooled OR = 1.48, 95% CI 1.02-2.13), but not for migraine without aura. Nine studies investigated the association of the ACE D/I polymorphism with migraine. The II genotype was associated with a reduced risk for migraine with aura (pooled OR = 0.71, 95% CI 0.55-0.93) and migraine without aura (pooled OR = 0.84, 95% CI 0.70-0.99). Results for both variants were driven by studies in non-Caucasian populations. Results among Caucasians did not suggest an association. Extractable data did not allow investigation of gene,gene interactions. Conslusions., The MTHFR 677TT genotype is associated with an increased risk for migraine with aura, while the ACE II genotype is protective against both migraine with and without aura. Results for both variants appeared only among non-Caucasian populations. There was no association among Caucasians. [source] SCHIP's Impact on Dependent Coverage in the Small-Group Health Insurance MarketHEALTH SERVICES RESEARCH, Issue 1 2010Eric E. Seiber Objective. To estimate the impact of State Children's Health Insurance Program (SCHIP) expansions on public and private coverage of dependents at small firms compared with large firms. Data Sources. 1996,2007 Annual Demographic Survey of the Current Population Survey (CPS). Study Design. This study estimates a two-stage least squares (2SLS) model for four insurance outcomes that instruments for SCHIP and Medicaid eligibility. Separate models are estimated for small group markets (firms with fewer than 25 employees), small businesses (firms under 500 employees), and large firms (firms 500 employees and above). Data Collection/Extraction Methods. We extracted data from the 1996,2007 CPS for children in households with at least one worker. Principal Findings. The SCHIP expansions decreased the percentage of uninsured dependents in the small group market by 7.6 percentage points with negligible crowd-out in the small group and no significant effect on private coverage across the 11-year-period. Conclusions. The SCHIP expansions have increased coverage for households in the small group market with no significant crowd-out of private coverage. In contrast, the estimates for large firms are consistent with the substantial crowd-out observed in the literature. [source] Assessing Treatment Effects of Inhaled Corticosteroids on Medical Expenses and Exacerbations among COPD Patients: Longitudinal Analysis of Managed Care ClaimsHEALTH SERVICES RESEARCH, Issue 6 2008Manabu Akazawa Objective. To assess costs, effectiveness, and cost-effectiveness of inhaled corticosteroids (ICS) augmenting bronchodilator treatment for chronic obstructive pulmonary disease (COPD). Data Sources. Claims between 1997 and 2005 from a large managed care database. Study Design. Individual-level, fixed-effects regression models estimated the effects of initiating ICS on medical expenses and likelihood of severe exacerbation. Bootstrapping provided estimates of the incremental cost per severe exacerbation avoided. Data Extraction Methods. COPD patients aged 40 or older with ,15 months of continuous eligibility were identified. Monthly observations for 1 year before and up to 2 years following initiation of bronchodilators were constructed. Principal Findings. ICS treatment reduced monthly risk of severe exacerbation by 25 percent. Total costs with ICS increased for 16 months, but declined thereafter. ICS use was cost saving 46 percent of the time, with an incremental cost-effectiveness ratio of $2,973 per exacerbation avoided; for patients ,50 years old, ICS was cost saving 57 percent of time. Conclusions. ICS treatment reduces exacerbations, with an increase in total costs initially for the full sample. Compared with younger patients with COPD, patients aged 50 or older have reduced costs and improved outcomes. The estimated cost per severe exacerbation avoided, however, may be high for either group because of uncertainty as reflected by the large standard errors of the parameter estimates. [source] The Impact of Welfare Reform on Insurance Coverage before Pregnancy and the Timing of Prenatal Care InitiationHEALTH SERVICES RESEARCH, Issue 4 2007Norma I. Gavin Objective. This study investigates the impact of welfare reform on insurance coverage before pregnancy and on first-trimester initiation of prenatal care (PNC) among pregnant women eligible for Medicaid under welfare-related eligibility criteria. Data Sources. We used pooled data from the Pregnancy Risk Assessment Monitoring System for eight states (AL, FL, ME, NY, OK, SC, WA, and WV) from 1996 through 1999. Study Design. We estimated a two-part logistic model of insurance coverage before pregnancy and first-trimester PNC initiation. The impact of welfare reform on insurance coverage before pregnancy was measured by marginal effects computed from coefficients of an interaction term for the postreform period and welfare-related eligibility and on PNC initiation by the same interaction term and the coefficients of insurance coverage adjusted for potential simultaneous equation bias. We compared the estimates from this model with results from simple logistic, ordinary least squares, and two-stage least squares models. Principal Findings. Welfare reform had a significant negative impact on Medicaid coverage before pregnancy among welfare-related Medicaid eligibles. This drop resulted in a small decline in their first-trimester PNC initiation. Enrollment in Medicaid before pregnancy was independent of the decision to initiate PNC, and estimates of the effect of a reduction in Medicaid coverage before pregnancy on PNC initiation were consistent over the single- and two-stage models. Effects of private coverage were mixed. Welfare reform had no impact on first-trimester PNC beyond that from reduced Medicaid coverage in the pooled regression but separate state-specific regressions suggest additional effects from time and income constraints induced by welfare reform may have occurred in some states. Conclusions. Welfare reform had significant adverse effects on insurance coverage and first-trimester PNC initiation among our nation's poorest women of childbearing age. Improved outreach and insurance options for these women are needed to meet national health goals. [source] The Unintended Impact of Welfare Reform on the Medicaid Enrollment of Eligible ImmigrantsHEALTH SERVICES RESEARCH, Issue 5 2004Namratha R. Kandula Background. During welfare reform, Congress passed legislation barring legal immigrants who entered the United States after August 1996 from Medicaid for five years after immigration. This legislation intended to bar only new immigrants (post-1996 immigrants) from Medicaid. However it may have also deterred the enrollment of legal immigrants who immigrated before 1996 (pre-1996 immigrants) and who should have remained Medicaid eligible. Objectives. To compare the Medicaid enrollment of U.S.-born citizens to pre-1996 immigrants, before and after welfare reform, and to determine if variation in state Medicaid policies toward post-1996 immigrants modified the effects of welfare reform on pre-1996 immigrants. Data Source/Study Design. Secondary database analysis of cross-sectional data from 1994,2001 of the U.S. Census Bureau, Annual Demographic Survey of March Supplement of the Current Population Survey. Subjects. Low-income, U.S.-born adults (N=116,307) and low-income pre-1996 immigrants (N=24,367) before and after welfare reform. Measures. Self-reported Medicaid enrollment. Results. Before welfare reform, pre-1996 immigrants were less likely to enroll in Medicaid than the U.S.-born (OR=0.55; 95 percent CI, 0.51,0.59). After welfare reform, pre-1996 immigrants were even less likely to enroll in Medicaid. The proportion of immigrants in Medicaid dropped 3 percentage points after 1996; for the U.S.-born it dropped 1.6 percentage points (p=0.012). Except for California, state variation in Medicaid policy toward post-1996 immigrants did modify the effect of welfare reform on pre-1996 immigrants. Conclusions. Federal laws limiting the Medicaid eligibility of specific subgroups of immigrants appear to have had unintended consequences on Medicaid enrollment in the larger, still eligible immigrant community. Inclusive state policies may overcome this effect. [source] Injured Workers' Underreporting in the Health Care Industry: An Analysis Using Quantitative, Qualitative, and Observational DataINDUSTRIAL RELATIONS, Issue 1 2010MONICA GALIZZI Underreporting of occupational injuries was examined in four health care facilities using quantitative, qualitative, and observational data. Occupational Safety and Health Administration logs accounted for only one-third of the workers' compensation records; 45 percent of injured workers followed by survey had workers' compensation claims. Workers reported 63 percent of serious occupational injuries. Underreporting is explained by time pressure and workers' doubts about eligibility, reputation, income loss, and career prospects. Though aware of underreporting, managers subtly believe in workers' moral hazard behaviors. [source] Refined avian risk assessment for aldicarb in the United StatesINTEGRATED ENVIRONMENTAL ASSESSMENT AND MANAGEMENT, Issue 1 2010Dwayne RJ Moore Abstract Aldicarb was recently reviewed by the US Environmental Protection Agency (USEPA) for re-registration eligibility. In this paper, we describe a refined avian risk assessment for aldicarb that was conducted to build upon the screening-level methods used by USEPA. The goal of the refined ERA was to characterize and understand better the risks posed by aldicarb to birds in areas where the pesticide is applied. Aldicarb is a systemic insecticide sold in granular form under the trade name Temik®. It is applied directly to soil and is used to control mites, nematodes, and aphids on a variety of crops (e.g., cotton, potatoes, peanuts). Consumption of grit is necessary for proper digestion in many bird species, particularly for granivores and insectivores. Thus, aldicarb granules may be mistaken for grit by birds. The Granular Pesticide Avian Risk Assessment Model (GranPARAM) is described in a companion paper and was used to estimate the probability and magnitude of effects to flocks of birds that frequent aldicarb-treated fields. One hundred thirty-five exposure scenarios were modeled that together include a range of bird species, crops, application methods and rates, and regions in the United States. The results indicated that, even for the most sensitive bird species, the risks associated with the agricultural use of granular aldicarb are negligible to low. There are several reasons for the limited risk: 1) the Temik formulation includes a gypsum core and a graphite coating and is black in color, all of which have been shown to be unattractive to birds, and 2) the pesticide is applied subsurface and rapidly dissolves following contact with water. The fact that no bird kill incidents involving appropriate label uses of aldicarb have been conclusively documented in the United States over its 38 years of use supports the results of this refined risk assessment.

Gellert Abstract Background: Hepatocellular cancer (HCC) is a serious complication of cirrhosis and chronic hepatitis B infection. The aim of the study was to determine the characteristics of patients with HCC presenting within the South West Sydney area, including an analysis of the rates and benefits of hepatocellular surveillance. Methods: Data from patients with HCC presenting to Liverpool and Bankstown Hospitals from July 1993 to June 2003 were analysed retrospectively, predominantly from hospital records. Results: Of the 151 HCC patients, 41% were Asian born. Most of the patients required an interpreter. Chronic viral hepatitis infection was present in 91 patients, of whom only 7% had previously received antiviral therapy. Alcohol alone was considered responsible in 31 patients. Cirrhosis could be documented in 58% of patients. Most of the patients (75%) presented symptomatically. The median survival was 5.1 months. When HCC was detected by surveillance, the tumours were slightly but not significantly more likely to be operable and the patients tended to be offered some form of active treatment more frequently. Multivariate analysis identified detection by surveillance, lower Child,Pugh score, smaller tumour size and eligibility for some form of treatment to be associated with a more favourable outcome. Conclusion: We observed low rates of surveillance for HCC, low recognition of cirrhosis before development of HCC and low rates of prior treatment of viral hepatitis. The poor outcome of HCC in the small group who had some sort of community surveillance is also a concern requiring further investigation. [source] CMA Candidate Attributes and Performance: Some Implications,ACCOUNTING PERSPECTIVES, Issue 1 2005MANMOHAN RAI KAPOOR ABSTRACT A university degree or equivalent is one of the criteria for eligibility to write the entrance examination for qualification as a certified management accountant (CMA). This study assessed various attributes, including exposure to liberal or general education, that candidates acquired during their university studies and examined the impact of these attributes on candidates' performance in the examination. The data included academic transcripts of 270 candidates who wrote the examination. Results indicated a positive, statistically significant correlation between the examination score and the candidate's exposure to liberal or general education, credit hours passed in accounting, grade point average in accounting, and grade point average in the overall course work. Credit hours failed in accounting showed a negative correlation. These findings are relevant to accounting educators, student counsellors, students, and the accountancy profession in general. [source] The clinical effectiveness of nurse practitioners' management of minor injuries in an adult emergency department: a systematic reviewINTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 1 2009Anne Wilson PhD, FRCNA Abstract Background, The increasing cost of healthcare in Australia demands changes in the way healthcare is delivered. Nurse practitioners have been introduced into specialty areas including emergency departments. Specific interventions are known to include the treatment and management of minor injuries, but little has been reported on their work. Objectives, Examine the best available evidence to determine the clinical effectiveness of emergency department nurse practitioners in the assessment, treatment and management of minor injuries in adults. Inclusion criteria, For inclusion studies had to include adult patients treated for minor injuries by nurse practitioners in emergency departments. All study designs were included. Search strategy, English language articles from 1986 onwards were sought using MEDLINE, CINAHL, Embase and Science Citation Index. Methodological quality, Two independent reviewers critically appraised the quality of the studies and extracted data using standardised tools. Data collection, Two independent reviewers assessed the eligibility of each study for inclusion into the review and the study design used. Where any disagreement occurred, consensus was reached by discussion with an independent researcher. Data synthesis, Studies were assessed for homogeneity by considering populations, interventions and outcomes. Where heterogeneity was present, synthesis was undertaken in a narrative format; otherwise a meta-analysis was conducted. For each outcome measure, results were tabulated by intervention type and discussed in a narrative summary. Results from randomised controlled trials were pooled in meta-analyses where appropriate. Results, Nine studies from a total of 55 participants met the inclusion criteria. Two were randomised controlled trials. Metasynthesis of research findings generated five synthesised findings derived from 16 study findings aggregated into seven categories. Evidence comparing the clinical effectiveness of nurse practitioners to mainstream management of minor injuries was fair to poor methodological quality. When comparable data were pooled, there were no significant differences (P < 0.05) between nurse practitioners and junior doctors. Conclusions, The results emphasise the need for more high-quality research using appropriate outcome measures in the area of clinical effectiveness of nurse practitioners, particularly interventions that improve outcomes for presentations to emergency departments and address issues of waiting and congestion. [source] Minimising undernutrition in the older inpatientINTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 2 2007Dawn Vanderkroft BSc internshipNutr&Diet APD Abstract Background, Malnutrition among elderly hospitalised patients is widespread and has been shown to lead to adverse health outcomes. The effectiveness of interventions to minimise undernutrition in elderly inpatients is not well documented. Objectives, To identify the best available practices, in the hospital setting, that minimise undernutrition or the risk of undernutrition, in the acute care patient especially for the older patient. The review will assesses the effectiveness of a range of interventions designed to promote adequate nutritional intake in the acute care setting, with the aim of determining what practices minimise malnutrition in the elderly inpatients. Search strategy, English language articles from 1980 onwards were sought using Medline, Premedline, Cinahl, Austrom-Australasian Medical Index and AustHealth, Embase and Science Citations Index. Selection criteria, For inclusion the study had to include an intervention aiming to minimise undernutrition in hospitalised elderly patients aged 65 years or older. All study designs were included. Data collection and analysis, Two independent reviewers assessed the eligibility of each study for inclusion into the review, critically appraised the study quality and extracted data using standardised tools. For each outcome measure results were tabulated by intervention type and discussed in a narrative summary. Results from randomised controlled trials were pooled in meta-analyses where appropriate. Main results, Twenty-nine studies met the inclusion criteria, with a total of 4021 participants. The focus of 15 interventions was the supplying of oral supplements to the participants, six focused on enteral nutrition therapy, four interventions made changes to the foods provided as part of the hospital diet, one included the services of an additional staff member and three incorporated the implementation of evidence-based guidelines. Ten meta-analyses were conducted from which the main findings were: significant improvements in weight status and arm muscle circumferences with an oral supplement intervention, P < 0.05. Reviewers' conclusions, The findings of the review support the use of oral supplements to minimise undernutrition in elderly inpatients. The results also emphasise the need for more high-quality research using appropriate outcome measures in the area of minimisation of undernutrition, particularly interventions that make alterations to the hospital diet and address support for feeding patients at the ward level. [source] Effectiveness of arthroscopic versus open surgical stabilisation for the management of traumatic anterior glenohumeral instabilityINTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 2 2007Choong Ng BMedSci(Melb) Abstract Background, Anterior instability is a frequent complication following a traumatic glenohumeral dislocation. Frequently the underlying pathology associated with recurrent instability is a Bankart lesion. Surgical correction of Bankart lesions and other associated pathology is the key to successful treatment. Open surgical glenohumeral stabilisation has been advocated as the gold standard because of consistently low postoperative recurrent instability rates. However, arthroscopic glenohumeral stabilisation could challenge open surgical repair as the gold standard treatment for traumatic anterior glenohumeral instability. Objectives, Primary evidence that compared the effectiveness of arthroscopic versus open surgical glenohumeral stabilisation was systematically collated regarding best-practice management for adults with traumatic anterior glenohumeral instability. Search strategy, A systematic search was performed using 14 databases: MEDLINE, Cumulative Index of Nursing and Allied Health (CINAHL), Allied and Complementary Medicine Database (AMED), ISI Web of Science, Expanded Academic ASAP, Proquest Medical Library, Evidence Based Medicine Reviews, Physiotherapy Evidence Database, TRIP Database, PubMed, ISI Current Contents Connect, Proquest Digital Dissertations, Open Archives Initiative Search Engine, Australian Digital Thesis Program. Studies published between January 1984 and December 2004 were included in this review. No language restrictions were applied. Selection criteria, Eligible studies were those that compared the effectiveness of arthroscopic versus open surgical stabilisation for the management of traumatic anterior glenohumeral instability, which had more than 2 years of follow up and used recurrent instability and a functional shoulder questionnaire as primary outcomes. Studies that used non-anatomical open repair techniques, patient groups that were specifically 40 years or older, or had multidirectional instability or other concomitant shoulder pathology were excluded. Data collection and analysis, Two independent reviewers assessed the eligibility of each study for inclusion into the review, the study design used and its methodological quality. Where any disagreement occurred, consensus was reached by discussion with an independent researcher. Studies were assessed for homogeneity by considering populations, interventions and outcomes. Where heterogeneity was present, synthesis was undertaken in a narrative format; otherwise a meta-analysis was conducted. Results, Eleven studies were included in the review. Two were randomised controlled trials. Evidence comparing arthroscopic and open surgical glenohumeral stabilisation was of poor to fair methodological quality. Hence, the results of primary studies should be interpreted with caution. Observed clinical heterogeneity in populations and outcomes was highlighted and should be considered when interpreting the meta-analysis. Authors also used variable definitions of recurrent instability and a variety of outcome measures, which made it difficult to synthesise results. When comparable data were pooled, there were no significant differences (P > 0.05) between the arthroscopic and open groups with respect to recurrent instability rates, Rowe score, glenohumeral external rotation range and complication rates. Conclusions, Statistically, it appears that both surgical techniques are equally effective in managing traumatic anterior glenohumeral instability. In light of the methodological quality of the included studies, it is not possible to validate arthoscopic stabilisation to match open surgical stabilisation as the gold standard treatment. Further research using multicentred randomised controlled trials with sufficient power and instability-specific questionnaires with sound psychometric properties is recommended to build on current evidence. The choice of treatment should be based on multiple factors between the clinician and the patient. [source] Lack of evidence of the effectiveness of primary brachial plexus surgery for infants (under the age of two years) diagnosed with obstetric brachial plexus palsyINTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 4 2006Andrea Bialocerkowski PhD M App Sc (Physio) M App Sc (Physio) Grad Dip Public Health Abstract Background, Obstetric brachial plexus palsy, which occurs in 1,3 per 1000 live births, results from traction and/or compression of the brachial plexus in utero, during descent through the birth canal or during delivery. This results in a spectrum of injuries that range in extent of damage and severity and can lead to a lifelong impairment and functional difficulties associated with the use of the affected upper limb. Most infants diagnosed with obstetric brachial plexus palsy receive treatment, such as surgery to the brachial plexus, physiotherapy or occupational therapy, within the first months of life. However, there is controversy regarding the most effective form of management. This review follows on from our previous systematic review which investigated the effectiveness of primary conservative management in infants with obstetric brachial plexus palsy. This systematic review focuses on the effects of primary surgery. Objectives, The objective of this review was to systematically assess and collate all available evidence on effectiveness of primary brachial plexus surgery for infants with obstetric brachial plexus palsy. Search strategy, A systematic literature search was performed using 13 databases: TRIP, MEDLINE, CINAHL, Web of Science, Proquest 5000, Evidence Based Medicine Reviews, Expanded Academic ASAP, Meditext, Science Direct, the Physiotherapy Evidence Database, Proquest Digital Dissertations, Open Archives Initiative Search Engine, the Australian Digital Thesis program. Those studies that were reported in English and published between July 1992 to June 2004 were included in this review. Selection criteria, Quantitative studies that investigated the effectiveness of primary brachial plexus surgery for infants with obstetric brachial plexus palsy were eligible for inclusion into this review. This excluded studies where infants were solely managed conservatively or with pharmacological agents, or underwent surgery for the management of secondary deformities. Data collection and analysis, Two independent reviewers assessed the eligibility of each study for inclusion into the review, the study design used and its methodological quality. Where any disagreement occurred, consensus was reached by discussion. Studies were also assessed for clinical homogeneity by considering populations, interventions and outcomes. Where heterogeneity was present, synthesis was undertaken in a narrative format. Results, Twenty-one studies were included in the review. Most were ranked low on the hierarchy of evidence (no randomised controlled trials were found), and most had only fair methodological quality. Surgical intervention was variable, as were the eligibility criteria for surgery, the timing of surgery and the outcome instruments used to evaluate the effect of surgery. Therefore, it is difficult to draw conclusions regarding the effectiveness of primary brachial plexus surgery for infants with obstetric brachial plexus palsy. Conclusions, Although there is a wealth of information regarding the outcome following primary brachial plexus surgery it was not possible to determine whether this treatment is effective in increasing functional recovery in infants with obstetric brachial plexus palsy. Further research is required to develop standardised surgical criteria, and standardised outcome measures should be used at specific points in time during the recovery process to facilitate comparison between studies. Moreover, comparison groups are required to determine the relative effectiveness of surgery compared with other forms of management. [source] Factors associated with constructive staff,family relationships in the care of older adults in the institutional settingINTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 4 2006Emily Haesler BN PGradDipAdvNsg Abstract Background, Modern healthcare philosophy espouses the virtues of holistic care and acknowledges that family involvement is appropriate and something to be encouraged due to the role it plays in physical and emotional healing. In the aged care sector, the involvement of families is a strong guarantee of a resident's well-being. The important role family plays in the support and care of the older adult in the residential aged care environment has been enshrined in the Australian Commonwealth Charter of Residents' Rights and Responsibilities and the Aged Care Standards of Practice. Despite wide acknowledgement of the importance of family involvement in the healthcare of the older adult, many barriers to the implementation of participatory family care have been identified in past research. For older adults in the healthcare environment to benefit from the involvement of their family members, healthcare professionals need an understanding of the issues surrounding family presence in the healthcare environment and the strategies to best support it. Objectives, The objectives of the systematic review were to present the best available evidence on the strategies, practices and organisational characteristics that promote constructive staff,family relationships in the care of older adults in the healthcare setting. Specifically this review sought to investigate how staff and family members perceive their relationships with each other; staff characteristics that promote constructive relationships with the family; and interventions that support staff,family relationships. Search strategy, A literature search was performed using the following databases for the years 1990,2005: Ageline, APAIS Health, Australian Family and Society Abstracts (FAMILY), CINAHL, Cochrane Library, Dare, Dissertation Abstracts, Embase, MEDLINE, PsycINFO and Social Science Index. Personal communication from expert panel members was also used to identify studies for inclusion. A second search stage was conducted through review of reference lists of studies retrieved during the first search stage. The search was limited to published and unpublished material in English language. Selection criteria, The review was limited to studies involving residents and patients within acute, subacute, rehabilitation and residential settings, aged over 65 years, their family and healthcare staff. Papers addressing family members and healthcare staff perceptions of their relationships with each other were considered for this review. Studies in this review also included those relating to interventions to promote constructive staff,family relationships including organisational strategies, staff,family meetings, case conferencing, environmental approaches, etc. The review considered both quantitative and qualitative research and opinion papers for inclusion. Data collection and analysis, All retrieved papers were critically appraised for eligibility for inclusion and methodological quality independently by two reviewers, and the same reviewers collected details of eligible research. Appraisal forms and data extraction forms designed by the Joanna Briggs Institute as part of the QARI and NOTARI systematic review software packages were used for this review. Findings, Family members' perceptions of their relationships with staff showed that a strong focus was placed on opportunities for the family to be involved in the patient's care. Staff members also expressed a theoretical support for the collaborative process, however, this belief often did not translate to the staff members' clinical practice. In the studies included in the review staff were frequently found to rely on traditional medical models of care in their clinical practice and maintaining control over the environment, rather than fully collaborating with families. Four factors were found to be essential to interventions designed to support a collaborative partnership between family members and healthcare staff: communication, information, education and administrative support. Based on the evidence analysed in this systematic review, staff and family education on relationship development, power and control issues, communication skills and negotiating techniques is essential to promoting constructive staff,family relationships. Managerial support, such as addressing workloads and staffing issues; introducing care models focused on collaboration with families; and providing practical support for staff education, is essential to gaining sustained benefits from interventions designed to promote constructive family,staff relationships. [source] Effectiveness of topical skin care provided in aged care facilitiesINTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 4 2005Brent Hodgkinson MSc GradCertPH GradCertEcon(Health) Executive summary Background, The 2001 Australian census revealed that adults aged 65 years and over constituted 12.6% of the population, up from 12.1% in 1996. It is projected that this figure will rise to 21% or 5.1 million Australians by 2031. In 1998, 6% (134 000) of adults in Australia aged 65 years and over were residing in nursing homes or hostels and this number is also expected to rise. As skin ages, there is a decreased turnover and replacement of epidermal skin cells, a thinning subcutaneous fat layer and a reduced production of protective oils. These changes can affect the normal functions of the skin such as its role as a barrier to irritants and pathogens, temperature and water regulation. Generally, placement in a long-term care facility indicates an inability of the older person to perform all of the activities of daily living such as skin care. Therefore, skin care management protocols should be available to reduce the likelihood of skin irritation and breakdown and ultimately promote comfort of the older person. Objectives, The objective of this review was to determine the best available evidence for the effectiveness and safety of topical skin care regimens for older adults residing in long-term aged care facilities. The primary outcome was the incidence of adverse skin conditions with patient satisfaction considered as a secondary outcome. Search strategy, A literature search was performed using the following databases: PubMed (NLM) (1966,4/2003), Embase (1966,4/2003), CINAHL (1966,4/2003), Current Contents (1993,4/2003), Cochrane Library (1966,2/2003), Web of Science (1995,12/2002), Science Citation Index Expanded and ProceedingsFirst (1993,12/2002). Health Technology Assessment websites were also searched. No language restrictions were applied. Selection criteria, Systematic reviews of randomised controlled trials, randomised and non-randomised controlled trials evaluating any non-medical intervention or program that aimed to maintain or improve the integrity of skin in older adults were considered for inclusion. Participants were 65 years of age or over and residing in an aged care facility, hospital or long-term care in the community. Studies were excluded if they evaluated pressure-relieving techniques for the prevention of skin breakdown. Data collection and analysis, Two independent reviewers assessed study eligibility for inclusion. Study design and quality were tabulated and relative risks, odds ratios, mean differences and associated 95% confidence intervals were calculated from individual comparative studies containing count data. Results, The resulting evidence of the effectiveness of topical skin care interventions was variable and dependent upon the skin condition outcome being assessed. The strongest evidence for maintenance of skin condition in incontinent patients found that disposable bodyworn incontinence protection reduced the odds of deterioration of skin condition compared with non-disposable bodyworns. The best evidence for non-pressure relieving topical skin care interventions on pressure sore formation found the no-rinse cleanser Clinisan to be more effective than soap and water at maintaining healthy skin (no ulcers) in elderly incontinent patients in long-term care. The quality of studies examining the effectiveness of topical skin care interventions on the incidence of skin tears was very poor and inconclusive. Topical skin care for prevention of dermatitis found that Sudocrem could reduce the redness of skin compared with zinc cream if applied regularly after each pad change, but not the number of lesions. Topical skin care on dry skin found the Bag Bath/Travel Bath no-rinse skin care cleanser to be more effective at preventing overall skin dryness and most specifically flaking and scaling when compared with the traditional soap and water washing method in residents of a long-term care facility. Information on the safety of topical skin care interventions is lacking. Therefore, because of the lack of evidence, no recommendation on the safety on any intervention included in this review can be made. [source] Effectiveness of primary conservative management for infants with obstetric brachial plexus palsyINTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 2 2005Andrea Bialocerkowski PhD MAppSc(Phty) GradDipPublicHealth Executive summary Background, Obstetric brachial plexus palsy, a complication of childbirth, occurs in 1,3 per 1000 live births internationally. Traction and/or compression of the brachial plexus is thought to be the primary mechanism of injury and this may occur in utero, during the descent through the birth canal or during delivery. This results in a spectrum of injuries that vary in severity, extent of damage and functional use of the affected upper limb. Most infants receive treatment, such as conservative management (physiotherapy, occupational therapy) or surgery; however, there is controversy regarding the most appropriate form of management. To date, no synthesised evidence is available regarding the effectiveness of primary conservative management for obstetric brachial plexus palsy. Objectives, The objective of this review was to systematically assess the literature and present the best available evidence that investigated the effectiveness of primary conservative management for infants with obstetric brachial plexus palsy. Search strategy, A systematic literature search was performed using 14 databases: TRIP, MEDLINE, CINAHL, AMED, Web of Science, Proquest 5000, Evidence Based Medicine Reviews, Expanded Academic ASAP, Meditext, Science Direct, Physiotherapy Evidence Database, Proquest Digital Dissertations, Open Archives Initiative Search Engine, Australian Digital Thesis Program. Those studies that were reported in English and published over the last decade (July 1992 to June 2003) were included in this review. Selection criteria, Quantitative studies that investigated the effectiveness of primary conservative management for infants with obstetric brachial plexus palsy were eligible for inclusion in this review. This excluded studies that solely investigated the effect of primary surgery for these infants, management of secondary deformities and the investigation of the effects of pharmacological agents, such as botulinum toxin. Data collection and analysis, Two independent reviewers assessed the eligibility of each study for inclusion into the review, the study design used and its methodological quality. Where any disagreement occurred, consensus was reached by discussion. Studies were assessed for clinical homogeneity by considering populations, interventions and outcomes. Where heterogeneity was present, synthesis was undertaken in a narrative format. Results, Eight studies were included in the review. Most were ranked low on the Hierarchy of Evidence (no randomised controlled trials were found), and had only fair methodological quality. Conservative management was variable and could consist of active or passive exercise, splints or traction. All studies lacked a clear description of what constituted conservative management, which would not allow the treatment to be replicated in the clinical setting. A variety of outcome instruments were used, none of which had evidence of validity, reliability or sensitivity to detect change. Furthermore, less severely affected infants were selected to receive conservative management. Therefore, it is difficult to draw conclusions regarding the effectiveness of conservative management for infants with obstetric brachial plexus palsy. Conclusions, There is scant, inconclusive evidence regarding the effectiveness of primary conservative intervention for infants with obstetric brachial plexus palsy. Further research should be directed to develop outcome instruments with sound psychometric properties for infants with obstetric brachial plexus palsy and their families. These outcome instruments should then be used in well-designed comparative studies. [source] Design of the fuzzy multiobjective controller based on the eligibility methodINTERNATIONAL JOURNAL OF INTELLIGENT SYSTEMS, Issue 5 2003Hwan-Chun Myung A multiobjective control problem has been handled in many different ways such as fuzzy, neural network and reinforcement learning, etc. Among them, a reinforcement learning method solves a multiobjective control problem without any prior knowledge. In this article, a new reinforcement learning method for a multiobjective control problem is proposed in consideration of its convergence. The proposed method, in which objective eligibility is considered for handling multirewards, reformulates a multiobjective control problem in a form of a reinforcement learning problem under non-Markov environment. Using a similar relation to eligibility, the proposed method dealt with the previous research results of eligibility and was implemented with the concept of a decoupled fuzzy sliding mode control (DFSMC). © 2003 Wiley Periodicals, Inc.

The paper focuses on identifying the relationship between ongoing mobility patterns and personal and environmental circumstances, including institutional barriers to immigration and a discrete change in the social welfare eligibility of New Zealanders in Australia. The results confirm that ongoing migration patterns are far more complex than traditional migration paradigms suggest, with repeat and return migration and ongoing mobility being an important part of actual migration experiences.
