Regular exercise can delay age-related risk factors and can maintain or improve physical health and activity in older adults leading to a decrease in fall risk. The purpose of this study was to compare 2 different interventions for fall prevention, tai chi (TC) and Otago, by examining lower extremity strength, balance, and spatiotemporal gait parameters in community-dwelling older women. We performed a randomized trial in which subjects were assigned to 1 of 2 groups: the TC group (n = 21; age, 72.8 ± 4.7 years, range: 65-83 years), which participated in a modified Sun-style TC exercise program; and the Otago group (n = 24; age, 71.5 ± 3.6 years, range: 65-79 years), which participated in the Otago exercise program. The Timed Up and Go (TUG) test, functional reach (FR) test, one-leg standing (OLS) test, 5 times sit-to-stand test (5×STS), 30-second sit-to-stand (30s STS) test, and gait parameters (gait velocity, step length, step width, stride time, and cadence) were measured before and after the intervention. Both groups showed statistically significant improvements in balance (TUG and OLS tests), lower extremity strength (5×STS and 30s STS tests), and spatiotemporal gait parameters, except for step width and step length (P < .05). The Otago group showed a significantly improved FR, whereas the TC group showed a significantly improved step length after the intervention (P < .05). Furthermore, the Otago group exhibited greater improvements in the TUG (P < .001), FR (P < .001), 5×CST (P < .01), and 30-second CST (P < .01) tests: a faster cadence (P < .001) and shorter stride time (P < .001) when compared with the TC group. The TC group showed greater improvements in the OLS test, step length, and step width (P < .01) and faster gait velocity (P < .05) than the Otago group. The findings from this study support the efficacy of the TC and Otago exercise programs in improving mobility in this sample of subjects. Furthermore, the Otago group showed greater improvement in lower extremity strength, whereas the TC group showed greater improvement in balance (OLS test). Also, the TC group showed a greater improvement in gait velocity after TC training program compared with the Otago exercise program. However, this study does not elucidate which exercise program is a more effective intervention method with older women for fall prevention.

This study aimed to determine the effects of a plant cultivation-based horticultural therapy program for elderly people with mental health problems. Pre- and post-test design with experimental and control groups. Twenty-eight elderly Korean people with mental health problems participated from April to June 2017 at a farm located in Suwon, South Korea. The participants were randomly assigned to either the control (n = 14) or horticultural therapy group (n = 14); the latter participated in once-weekly sessions of a previously designed 10-session horticultural therapy program. The pre-test occurred 1 week before starting the horticultural therapy program. The post-test was completed within 1 week after finishing the final program session. Cortisol levels were measured in saliva samples collected from both groups. The Senior Fitness Test was used to assess physical functional ability in both groups. In the horticultural therapy group, the cortisol levels decreased significantly from before to after the horticultural therapy program, and the post-test scores for six subtests of the Senior Fitness Test improved significantly. No significant improvements were seen in either measure in the control group. This study demonstrates the potential ability of horticultural therapy to improve the stress levels and physical functional abilities of elderly people with mental health problems. In future studies, it would be interesting to verify the long-term effects of this horticultural therapy program and to compare its effects with regard to sex, age, and various mental symptoms.

1978-01-01

The product/study double bypass variable cycle engine (VCE) was updated to incorporate recent improvements. The effect of these improvements on mission range and noise levels was determined. This engine design was then compared with current existing high-technology core engines in order to define a subscale testbed configuration that simulated many of the critical technology features of the product/study VCE. Detailed preliminary program plans were then developed for the design, fabrication, and static test of the selected testbed engine configuration. These plans included estimated costs and schedules for the detail design, fabrication and test of the testbed engine and the definition of a test program, test plan, schedule, instrumentation, and test stand requirements.

2016-05-01

We recently proposed scenario decomposition algorithm for stochastic 0-1 programs finds an optimal solution by evaluating and removing individual solutions that are discovered by solving scenario subproblems. In our work, we develop an asynchronous, distributed implementation of the algorithm which has computational advantages over existing synchronous implementations of the algorithm. Improvements to both the synchronous and asynchronous algorithm are proposed. We also test the results on well known stochastic 0-1 programs from the SIPLIB test library and is able to solve one previously unsolved instance from the test set.

CDC's 2012 Hepatitis Testing and Linkage to Care (HepTLC) initiative was a nationally coordinated effort to conduct hepatitis B and hepatitis C screening, posttest counseling, and linkage to care at 34 U.S. sites. This project provided support for data management and monthly data reviews between awardees and a data manager, which facilitated monitoring of awardee progress and regular program improvement opportunities. CDC provided technical assistance to awardees for testing processes and program improvement, including Internet-based data submission, reporting software and data management to awardees, offering assistance with submitting, and reviewing data in real time. We describe how one awardee, AIDS Resource Center of Wisconsin (ARCW), used the data management process to improve data quality, inform testing processes and implementation, and measure and report missing variables from an online database. From October 2012 through July 2014, ARCW performed 2,255 HCV antibody (anti-HCV) tests and 244 HCV ribonucleic acid (RNA) tests as part of the HepTLC initiative. Participants who tested HCV RNA positive (n=189) were referred to medical care. At the end of the study, no records were missing for the anti-HCV test result or HCV RNA test result variables, and only one record was missing for those who were referred to medical care. Regular data review and monitoring by awardees and CDC-supported data managers provided opportunities for data quality and program improvement. Through regular data review, ARCW reduced the amount of missing data and promoted timely follow-up with participants testing positive for HCV to ensure receipt of results and linkage to care. Other programs can adopt a similar data management model.

To compare the effect of two 10-week balance training programs, Combined Balance and Step Training (CBST) versus tai chi (TC), on balance and stepping measures. Prospective intervention trial. Local senior centers and congregate housing facilities. Aged 65 and older with at least mild impairment in the ability to perform unipedal stance and tandem walk. Participants were allocated to TC (n = 107, mean age 78) or CBST, an intervention focused on improving dynamic balance and stepping (n = 106, mean age 78). At baseline and 10 weeks, participants were tested in their static balance (Unipedal Stance and Tandem Stance (TS)), stepping (Maximum Step Length, Rapid Step Test), and Timed Up and Go (TUG). Performance improved more with CBST than TC, ranging from 5% to 10% for the stepping tests (Maximum Step Length and Rapid Step Test) and 9% for TUG. The improvement in TUG represented an improvement of more than 1 second. Greater improvements were also seen in static balance ability (in TS) with CBST than TC. Of the two training programs, in which variants of each program have been proven to reduce falls, CBST results in modest improvements in balance, stepping, and functional mobility versus TC over a 10-week period. Future research should include a prospective comparison of fall rates in response to these two balance training programs.

Benefits of a Pharmacology Antimalarial Reference Standard and Proficiency Testing Program Provided by the Worldwide Antimalarial Resistance Network (WWARN)

Comprehensive assessment of antimalarial drug resistance should include measurements of antimalarial blood or plasma concentrations in clinical trials and in individual assessments of treatment failure so that true resistance can be differentiated from inadequate drug exposure. Pharmacometric modeling is necessary to assess pharmacokinetic-pharmacodynamic relationships in different populations to optimize dosing. To accomplish both effectively and to allow comparison of data from different laboratories, it is essential that drug concentration measurement is accurate. Proficiency testing (PT) of laboratory procedures is necessary for verification of assay results. Within the Worldwide Antimalarial Resistance Network (WWARN), the goal of the quality assurance/quality control (QA/QC) program is to facilitate and sustain high-quality antimalarial assays. The QA/QC program consists of an international PT program for pharmacology laboratories and a reference material (RM) program for the provision of antimalarial drug standards, metabolites, and internal standards for laboratory use. The RM program currently distributes accurately weighed quantities of antimalarial drug standards, metabolites, and internal standards to 44 pharmacology, in vitro, and drug quality testing laboratories. The pharmacology PT program has sent samples to eight laboratories in four rounds of testing. WWARN technical experts have provided advice for correcting identified problems to improve performance of subsequent analysis and ultimately improved the quality of data. Many participants have demonstrated substantial improvements over subsequent rounds of PT. The WWARN QA/QC program has improved the quality and value of antimalarial drug measurement in laboratories globally. It is a model that has potential to be applied to strengthening laboratories more widely and improving the therapeutics of other infectious diseases. PMID:24777099

The purposes of this study was to develop a comprehensive community-based fall prevention program and to test the effects of the program on the muscle strength, postural balance and fall efficacy for elderly people. The design of this study was a nonequivalent control group pretest-posttest design. There were 28 participants in the experimental group and 29 in the control group. The program consisted of balance exercises, elastic resistance exercises and prevention education. The program was provided five times a week for 8 weeks and each session lasted 90 minutes. Data were analyzed using χ²-test, independent t-test and paired t-test using the SPSS program. Muscle strength of the lower extremities, postural balance and fall efficacy scores significantly improved in the experimental group compared to the control group. These results suggest that this program can improve lower extremity muscle strength, postural balance and fall efficacy in elders. Therefore, this program is recommended for use in fall prevention programs for elders living in the community.

Improving knowledge and beliefs about mental health (or mental health literacy [MHL]) may promote appropriate help-seeking by adolescents who are suffering from mental health problems. We developed a concise, school-staff-led MHL program and examined its effects. The participants comprised 118 grade-9 students (61 boys and 57 girls). The program consisted of two 50-min sessions, and was given by a schoolteacher. The effects of the program were evaluated before, immediately after and 3 months after the program, using a self-report questionnaire. Knowledge of mental health/illnesses and desirable behavior for help-seeking were significantly improved immediately after (post-test, P < 0.001, and P < 0.001, respectively) and 3 months after the program (3-month follow up, P < 0.001 and P < 0.001, respectively), compared with the test before the delivery of the program (pre-test, Wilcoxon signed rank test). Proportions of the correct diagnoses of vignette cases of major depression and schizophrenia were significantly (P < 0.001) elevated from 38.3% and 19.1% (pre-test) to 94.7% and 93.6% (post-test), and 91.5% and 86.2% (3-month follow up). Intentions to seek help and to provide peers with help with mental health problems were also significantly (P < 0.001) elevated at post-test and at 3 months compared with the pre-test. A concise, school-staff-led program may have a significant effect on the improvement of MHL in secondary school students. © 2015 The Authors.

School-based health promotion programs have been shown to reduce the incidence of obesity in students and improve student physical fitness. However, few longitudinal evaluations of the effectiveness of such programs have been conducted. The purpose of this study was to assess the effectiveness of an in-school weight control program. Data was collected prior to and after the school's summer vacation period. The study utilized a one-group pretest-posttest design. Overweight and obese children from the fifth grade in an elementary school in Taipei City were selected as purposive samples. The study, which was conducted between March and June 2007, introduced general obesity concepts, taught basic nutrition education, and organized a physical activity program that comprised two 45-min exercise sessions during the week and one 30-min session activity each weekend. The obesity index assessed the body mass index (BMI) and waist-to-height ratio (WHtR), with physical fitness tests conducted before and after student summer vacations to assess achieved weight control results. The nonparametric test and repeat measure were used to assess weight control program effectiveness. After the weight control program, significant declines in BMI and WHtR (p < .001), significant improvements in 800-m run/walk (p < .01) and 1-minute sit-up tests (p < .05) were recorded. However, no significant comparative improvement was achieved on either obesity index or physical fitness test. Weight control programs represent an effective approach to reduce BMI and WHtR and improve physical fitness. An appropriate diet and exercise are important for school-aged children to maintain effective weight control and physical fitness health.

2016-01-01

The aging of the workforce poses new challenges for maintaining work ability. Because of limited information on the effectiveness of vocational rehabilitation performed in traditional inpatient programs, extended interest in outpatient rehabilitation has risen in the past few years. We examined the effects of a new outpatient rehabilitation program where every participant defined their own goals to improve work ability by the aid of a goal-oriented multi-professional team. This report will focus on the employees' physical capacity during a nine-month program. A total of 605 municipal employees from different production areas of the City of Tampere took part in the outpatient rehabilitation program, implemented by the occupational health unit. Groups of 12 employees participated in eight one-day sessions at intervals of two to three weeks; the final follow-up was 9 months from the beginning. Submaximal aerobic capacity was tested by a calibrated cycle ergometer with a commercial program (Aino Fitware pro, Helsinki, Finland). Musculoskeletal tests assessed muscle strength, balance and mobility. During the 9-month follow-up of the rehabilitation program, the employees' physical capacity was improved. The follow-up test scores from a total of 329 employees were significantly higher in the submaximal aerobic capacity test (p < 0.001). Other tests were also improved, such as standing on one foot (p = 0.001), back side bending flexibility test (p < 0.001), dynamic sit up (p = 0.001), upper extremity right (p < 0.001), and knee bending (p = 0.029). About 40% of the participants did not have an adequate health situation to take part in physical capacity tests; however they took part in the intervention. The new outpatient rehabilitation program organized by the occupational health unit had a positive influence on employees' physical capacity during a nine-month follow up.

The purpose of this study was to determine the 2-year impact of a worksite-based diabetes prevention program. Thirty-seven pre-diabetic and previously undiagnosed diabetic employees participating in a 12-month worksite diabetes prevention program were included. Weight, body mass index, waist circumference, oral glucose tolerance testing, fasting insulin, blood lipids, and aerobic fitness had improved significantly after 6 months. Much of this improvement continued through 12 months. One year following the intervention, oral glucose tolerance and aerobic fitness had improved significantly. Of the 22 employees remaining in the study through 24 months, more than half had normal results on glucose tolerance testing. Worksite diabetes prevention programs may reduce blood glucose below pre-diabetic and diabetic levels. Improvements in diabetes risk factors persisted for at least 2 years in most of these employees.

NASA Astrophysics Data System (ADS)

Tremoulet, P. C.

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

Implementing an educational program to improve critical care nurses' enteral nutritional support.

PubMed

Kim, Hyunjung; Chang, Sun Ju

2018-05-11

Although international nutrition societies recommend enteral nutrition guidelines for patients in intensive care units (ICUs), large gaps exist between these recommendations and actual clinical practice. Education programs designed to improve nurses' knowledge about enteral nutrition are therefore required. In Korea, there are no educational intervention studies about evidence-based guidelines of enteral nutrition for critically ill patients. We aimed to evaluate the effects of an education program to improve critical care nurses' perceptions, knowledge, and practices towards providing enteral nutritional support for ICU patients. A quasi-experimental, one-group study with a pre- and post-test design was conducted from March to April 2015. Nurses (N = 205) were recruited from nine ICUs from four tertiary hospitals in South Korea. The education program comprised two sessions of didactic lectures. Data were collected before (pre-test) and 1 month after (post-test) the education program using questionnaires that addressed nurses' perceptions, knowledge, and practices relating to providing enteral nutritional support for ICU patients. After the program, nurses showed a significant improvement in their perceptions and knowledge of enteral nutrition for ICU patients. There was a significant improvement in inspecting nostrils daily, flushing the feeding tube before administration, providing medication that needs to be crushed correctly, changing feeding sets, and adjusting feeding schedules. The findings indicate that an enteral nutrition education program could be an effective strategy to increase critical care nurses' support for the critically ill. This education program can be incorporated into hospital education or in-service training for critical care nurses to strengthen their perceptions and knowledge of nutritional support in the ICU. This may improve the clinical outcomes of ICU patients. Copyright © 2018 Australian College of Critical Care Nurses Ltd. Published by Elsevier Ltd. All rights reserved.

1989-01-01

NASA's program in aircraft icing research and technology is reviewed. The program relies heavily on computer codes and modern applied physics technology in seeking icing solutions on a finer scale than those offered in earlier programs. Three major goals of this program are to offer new approaches to ice protection, to improve our ability to model the response of an aircraft to an icing encounter, and to provide improved techniques and facilities for ground and flight testing. This paper reviews the following program elements: (1) new approaches to ice protection; (2) numerical codes for deicer analysis; (3) measurement and prediction of ice accretion and its effect on aircraft and aircraft components; (4) special wind tunnel test techniques for rotorcraft icing; (5) improvements of icing wind tunnels and research aircraft; (6) ground de-icing fluids used in winter operation; (7) fundamental studies in icing; and (8) droplet sizing instruments for icing clouds.

2000-01-01

Sixty native-born Swedish unemployed participants with reading and writing disabilities (R&WD) participated in a 20-week educational program aimed at improving reading and writing, verbal memory, self-confidence, and flexibility of perspectives. They were tested with a comprehensive battery (interviews, questionnaires, neuropsychological tests, and tests of academic achievement) before and after the intervention. Sixteen controls, matched for sex, age, education, and nonverbal IQ, participated in the pre- and posttest sessions but received only standard unemployment interventions. The educational program participants' performance in tests assessing spelling, decoding of letters, self-confidence, and flexibility improved significantly in comparison with the controls after the intervention. A significantly larger number of the participants had obtained work or started a regular education than expected. A substantial proportion of unemployed participants have R&WD and it appears that an intensive but fairly short educational program can improve their accessibility to the labor market and their motivation for study.

Emergency radiobioassay preparedness exercises through the NIST radiochemistry intercomparison program.

PubMed

Nour, Svetlana; LaRosa, Jerry; Inn, Kenneth G W

2011-08-01

The present challenge for the international emergency radiobioassay community is to analyze contaminated samples rapidly while maintaining high quality results. The National Institute of Standards and Technology (NIST) runs a radiobioassay measurement traceability testing program to evaluate the radioanalytical capabilities of participating laboratories. The NIST Radiochemistry Intercomparison Program (NRIP) started more than 10 years ago, and emergency performance testing was added to the program seven years ago. Radiobioassay turnaround times under the NRIP program for routine production and under emergency response scenarios are 60 d and 8 h, respectively. Because measurement accuracy and sample turnaround time are very critical in a radiological emergency, response laboratories' analytical systems are best evaluated and improved through traceable Performance Testing (PT) programs. The NRIP provides participant laboratories with metrology tools to evaluate their performance and to improve it. The program motivates the laboratories to optimize their methodologies and minimize the turnaround time of their results. Likewise, NIST has to make adjustments and periodical changes in the bioassay test samples in order to challenge the participating laboratories continually. With practice, radioanalytical measurements turnaround time can be reduced to 3-4 h.

Background: Neonatal pain management guidelines have been released; however, there is insufficient systematic institutional support for the adoption of evidence-based pain management in Japan. Purpose: To evaluate the impact of a collaborative quality improvement program on the implementation of pain management improvements in Japanese neonatal intensive care units (NICUs). Methods: Seven Japanese level III NICUs participated in a neonatal pain management quality improvement program based on an Institute for Healthcare Improvement collaborative model. The NICUs developed evidence-based practice points for pain management and implemented these over a 12-month period. Changes were introduced through a series of Plan-Do-Study-Act cycles, and throughout the process, pain management quality indicators were tracked as performance measures. Jonckheere's trend test and the Cochran-Armitage test for trend were used to examine the changes in quality indicator implementations over time (baseline, 3 months, 6 months, and 12 months). Findings: Baseline pain management data from the 7 sites revealed substantial opportunities for improvement of pain management, and testing changes in the NICU setting resulted in measurable improvements in pain management. During the intervention phase, all participating sites introduced new pain assessment tools, and all sites developed electronic medical record forms to capture pain score, interventions, and infant responses to interventions. Implications for Practice: The use of collaborative quality improvement techniques played a key role in improving pain management in the NICUs. Implications for Research: Collaborative improvement programs provide an attractive strategy for solving evidence-practice gaps in the NICU setting. PMID:28114148

The purpose of the present study was to examine the effect of a group-based task oriented skills training program on motor and physical ability for children with DCD. It was also investigated if there was an effect on fine motor and handwriting tasks that were not specifically practiced during the training program. Forty-one children aged 6-10years took part in this study. Children were assigned to three groups: an experimental training group consisting of 14 children with DCD, a control non-training group consisted of 13 children with DCD and a control non-training group consisting of 14 typically developed children. The measurements included were, the Movement Assessment Battery for Children (MABC), the Modified Agility Test (MAT), the Triple Hop Distance (THD), the 5 Jump-test (5JT) and the Handwriting Performance Test. All measures were administered pre and post an 8-week training program. The results showed that 10 children of the DCD training-group improved their performance in MABC test, attaining a score above the 15th percentile after their participation in the training program. DCD training-group showed a significant improvement on all cluster scores (manual dexterity (t (13)=5.3, p<.001), ball skills (t (13)=2.73, p<.05) and balance (t (13)=5.13, p<.001). Significant performance improvements were also found in MAT, THD, 5JT (t (13)=-4.55; p<.01), handwriting quality (t (12)=-2.73; p<.05) and speed (t (12)=-4.2; p<.01) after the training program. In conclusion, improvement in both practiced and non-practiced skills, in the training program, may reflect improvement in motor skill but also transfer to other skills.

A decline in cognitive ability commonly occurs among older individuals. This study sought to explore the restorative effects of exercise in older patients with existing cognitive disabilities. Ninety-six patients with mild cognitive impairment were placed in an exercise program for six months. Following completion of the program, participants were assessed via the Chinese Mini Mental Status Examination (MMSE), Activity of Daily Living (ADL) assessment, and body movement testing and compared to a control group of patients with mild cognitive impairment who did not participate in the exercise program (N = 102). Statistical analyses were performed using the Student’s t-test and chi-square test to compare results between groups. Compared with control group, patients who exercised showed improved cognitive function in immediate memory (p < 0.001) and delayed recall (p = 0.004) function. In addition, activities associated with daily living showed improvement (p < 0.001), as did body movement (p < 0.05), arm stability (p < 0.001), and the appearance of rotation (p < 0.05). Based on these results, we conclude that participation in an exercise program can improve patients’ cognitive function, physical abilities, and body movement capacity. PMID:25419345

The United States Air Force combat controller (CCT) training pipeline is extremely arduous and historically has a high attrition rate of 70 to 80%. The primary objective of this study was to evaluate the impact of incorporating a 711 Human Performance Wing (HPW) / Biobehavior, Bioassessment, and Biosurveillance Branch (RHPF)-developed physical fitness-training program into the combat controller (CCT) 5-level training physical fitness program. One-hundred-nine CCT trainees were tested and trained during their initial eight weeks at the 720th Special Tactics Training Squadron (STTS) at Hurlburt Field. Modifications to their physical training program were principally aimed at reducing overtraining and overuse injury, educating trainees and cadre on how to train smarter, and transitioning from traditional to "functional" PT. A battery of physiological measurements and a psychological test were administered prior to and immediately after trainees undertook an 8-week modified physical fitness training program designed to reduce overtraining and injury and improve performance. We performed multiple physical tests for cardiovascular endurance (VO₂max and running economy), "anaerobic" capacity (Wingate power and loaded running tests), body composition (skinfolds), power (Wingate and vertical jump), and reaction time (Makoto eye-hand test). We used the Mental Toughness Questionnaire 48 (MTQ-48) for the psychological test. We observed several significant improvements in physical and physiological performance over the eight weeks of training. Body composition improved by 16.2% (p < 0.05). VO₂max, time-to-exhaustion, and ventilatory threshold were all significantly higher after implementation of the new program than before it. We observed strong trends towards improvement in work accomplished during loaded running (p = 0.07) and in average power per body mass during lower body Wingate (p = 0.08). Other measures of lower body power did not change significantly over the training period, but did show mild trends towards improvement. Upper body average and peak power per kilogram of body mass both improved significantly by 5.8% and 8.1%, respectively. Reaction time was significantly better posttraining as demonstrated by a 7% improvement during the reactive test. Reactive accuracy also improved significantly with the post test accuracy percentage jumping from 61% to 76%. Furthermore, overuse injuries, a major source of attrition fell by a dramatic 67%. The modifications resulted in significant improvement in trainees? graduation rate. In the eight classes prior to implementation of these changes, average CCT graduating class size was nine trainees. For the eight classes following the changes, average CCT graduating class rose to 16.5 trainees, an increase of 83%. Due to its success, STTS leadership expanded the modifications from the eight weeks prior to CDS to include the entire second year of the pipeline. 2011.

This study compared the effectiveness of an AIDS knowledge-only program (knowledge) with a combined program of AIDS knowledge and contact with people having HIV/AIDS (PHA) (knowledge-contact) in reducing nursing students' stigma and discrimination towards PHA and in enhancing their emotional competence to serve PHA. Eighty-nine nursing students from two universities in Hong Kong were randomly assigned to either the knowledge or the knowledge-contact condition. All participants completed measures of AIDS knowledge, stigmatizing attitudes, fear of contagion, willingness to treat, positive affect, and negative affect at pre-test, post-test, and six-week follow-up. Findings showed that in both groups, significant improvement in AIDS knowledge, stigmatizing attitudes, fear of contagion, willingness to treat, and negative affect were found at post-test. The effects on AIDS knowledge, fear of contagion, willingness to treat, and negative affect were sustained at follow-up for both groups. Intergroup comparisons at post-test showed that the effectiveness of knowledge-contact program was significantly greater than knowledge program in improving stigmatizing attitudes. No significant difference between the two groups was found at follow-up. Findings showed the short-term effect of contact in improving nursing students' attitudes and emotional competence in serving PHA. Implications for research and training of nursing staff were discussed. Copyright (c) 2010 Elsevier Ltd. All rights reserved.

Integrating POC CD4 testing technologies into HIV counseling and testing (HCT) programs may improve post-HIV testing linkage to care and treatment. As evaluations of these technologies in program settings continue, estimates of the costs of POC CD4 tests to the service provider will be needed and estimates have begun to be reported. Without a consistent and transparent methodology, estimates of the cost per CD4 test using POC technologies are likely to be difficult to compare and may lead to erroneous conclusions about costs and cost-effectiveness. This paper provides a step-by-step approach for estimating the cost per CD4 test from a provider's perspective. As an example, the approach is applied to one specific POC technology, the Pima Analyzer. The costing approach is illustrated with data from a mobile HCT program in Gauteng Province of South Africa. For this program, the cost per test in 2010 was estimated at $23.76 (material costs  = $8.70; labor cost per test  = $7.33; and equipment, insurance, and daily quality control  = $7.72). Labor and equipment costs can vary widely depending on how the program operates and the number of CD4 tests completed over time. Additional costs not included in the above analysis, for on-going training, supervision, and quality control, are likely to increase further the cost per test. The main contribution of this paper is to outline a methodology for estimating the costs of incorporating POC CD4 testing technologies into an HCT program. The details of the program setting matter significantly for the cost estimate, so that such details should be clearly documented to improve the consistency, transparency, and comparability of cost estimates.

1973-01-01

Hermetically sealed, wound, AC, polycarbonate capacitors incorporating design improvements recommended in a previous study were designed and built. A 5000 hour, 400 Hz ac life test was conducted using 384 of these capacitors to verify the adequacy of the design improvements. The improvements incorporated in the capacitors designed for this program eliminated the major cause of failure found in the preceding work, termination failure. A failure cause not present in the previous test became significant in this test with capacitors built from one lot of polycarbonate film. The samples from this lot accounted for 25 percent of the total test complement. Analyses of failed samples showed that the film had an excessive solvent content. This solvent problem was found in 37 of the total 46 failures which occurred in this test. The other nine were random failures resulting from causes such as seal leaks, foreign particles, and possibly wrinkles.

The hypothesis of this study is that intensive therapy by means of a sensory and motor stimulation program of the upper limb in patients with chronic hemiparesis and severe disability due to stroke increases mobility and sensibility, and improves the use of the affected limb in activities of daily living (ADL). The program consists of 16 sessions of sensory stimulation and functional activity training in the rehabilitation center, and daily sessions of tactile stimulation, mental imaginery and practice of ADL at home, during 8 weeks. An experimental group (EG) of 12 patients followed this program, compared with a control group (CG) of 9 patients under standard rehabilitation. The efficacy of the program was evaluated by Fugl Meyer Assessment (FMA), Motor Activity Log (MAL) and Stroke Impact Scale-16 (SIS-16) scores, and a battery of sensory tests. The results show that in both groups, the motor FMA and the SIS-16 improved during the 8 weeks, this improvement being higher in the EG. Significant improvements were observed for the sensory tests in the EG. The intensive sensorimotor stimulation program for the upper extremity may be an efficacious method for improving function and use of the affected limb in ADL in chronic stroke patients.

Two 6-week programs including OKC, CKC, and core-stabilization exercises that were progressed each week. Functional throwing-performance index, closed kinetic chain upper extremity stability test, back-extensor test, 45 degrees abdominal-fatigue test, and right- and left-side bridging test. There was no significant difference between groups. An increase was evident in all pretest-to-posttest results, with improvement ranging from 1.36% to 140%. Both of the 6-week training programs could be used to increase throwing accuracy, core stability, and proprioception in baseball.

Testing and development of electric vehicle batteries for EPRI Electric Transportation Program

NASA Astrophysics Data System (ADS)

1985-11-01

Argonne National Laboratory conducted an electric-vehicle battery testing and development program for the Electric Power Research Institute. As part of this program, eighteen battery modules previously developed by Johnson Controls, Inc. were tested. This type of battery (EV-2300 - an improved state-of-the-art lead-acid battery) was designed specifically for improved performance, range, and life in electric vehicles. In order to obtain necessary performance data, the batteries were tested under various duty cycles typical of normal service. This program, supported by the Electric Power Research Institute, consisted of three tasks: determination of the effect of cycle life vs peak power and rest period, determination of the impact of charge method on cycle life, and evaluation of the EV-2300 battery system. Two supporting studies were also carried out: one on thermal management of electric-vehicle batteries and one on enhanced utilization of active material in lead-acid batteries.

Plyometrics is a popular training modality for basketball players to improve power and change-of-direction speed. Most plyometric training has used sagittal-plane exercises, but improvements in change-of-direction speed have been greater in multi-direction programs. To determine the benefits of a 6-wk frontal-plane plyometric (FPP) training program compared with a 6-wk sagittal-plane plyometric (SPP) training program with regard to power and change-of-direction speed. Fourteen female varsity high school basketball players participated in the study. Multiple 2 × 2 repeated-measures ANOVAs were used to determine differences for the FPP and SPP groups from preintervention to postintervention on 4 tests of power and 2 tests of change-of-direction speed. There was a group main effect for time in all 6 tests. There was a significant group × time interaction effect in 3 of the 6 tests. The SPP improved performance of the countermovement vertical jump more than the FPP, whereas the FPP improved performance of the lateral hop (left) and lateral-shuffle test (left) more than the SPP. The standing long jump, lateral hop (right), and lateral-shuffle test (right) did not show a significant interaction effect. These results suggest that basketball players should incorporate plyometric training in all planes to improve power and change-of-direction speed.

The purpose of the crash safety program is to support development of the technology to define and demonstrate new structural concepts for improved crash safety and occupant survivability in general aviation aircraft. The program involves three basic areas of research: full-scale crash simulation testing, nonlinear structural analyses necessary to predict failure modes and collapse mechanisms of the vehicle, and evaluation of energy absorption concepts for specific component design. Both analytical and experimental methods are being used to develop expertise in these areas. Analyses include both simplified procedures for estimating energy absorption capabilities and more complex computer programs for analysis of general airframe response. Full-scale tests of typical structures as well as tests on structural components are being used to verify the analyses and to demonstrate improved design concepts.

Individuals with intellectual and developmental disabilities (IDD) are in need of effective physical fitness training programs. The aim was to test the effectiveness of a Virtual Reality (VR)-based exercise program in improving the physical fitness of adults with IDD. A research group (N=30; mean age=52.3+/-5.8 years; moderate IDD level) was matched for age, IDD level and functional abilities with a control group (N=30, mean age=54.3+/-5.4 years). A 5-6 week fitness program consisting of two 30 min sessions per week included game-like exercises provided by the Sony PlayStation II EyeToy VR system. Changes in physical fitness were monitored by the Energy Expenditure Index (EEI), the modified 12 min walk/run and the Total Heart Beat Index (THBI). Significant (p<0.05) improvements in physical fitness were demonstrated for the research group in comparison to the control group for the Modified Cooper test and the THBI but not for the EEI test. The EEI, Modified Cooper and THBI tests were found feasible to evaluate physical fitness levels and change of individuals with IDD under clinical conditions. VR technology intervention was suitable for adults with IDD and resulted in significant improvements in the physical fitness levels of the participants.

Mobile technologies hold promise for improving diet and physical activity, but little attention is given to creating programs that adolescents like and will use. This study developed a personal digital assistant (PDA) program to promote increased intake of fruits and vegetables (FV) in predominately low-income, ethnic minority girls. This study used a three-phase community-engaged process, including (i) engagement of a Student Advisory Board (SAB) to determine comfort with PDAs; (ii) early testing of Prototype I and rapid re-design by the SAB and (iii) feasibility testing of Prototype II in a new sample of girls. Phase 1 results showed that girls were comfortable with the PDA. Testing of Prototype I in Phase 2 showed that acceptability was mixed, with girls responding to 47.3% of the prompts. Girls wanted more reminders, accountability in monitoring FV, help in meeting daily goals and free music downloads based on program use. The PDA was reprogrammed and testing of Prototype II in Phase 3 demonstrated marked improvement in use (78.3%), increases in FV intake (1.8 ± 2.6 daily servings) and good overall satisfaction. Findings suggest that mobile technology designed with the early input of youth is a promising way to improve adolescent health behaviors. PMID:22949499

Most work sites engage in some form of health promotion programming designed to improve worker health and reduce health care costs. Although these programs have typically been delivered through combinations of seminars and print materials, workplace health promotion programs are increasingly being delivered through the Internet. The purpose of this research was to evaluate the effectiveness of a Web-based multimedia health promotion program for the workplace, designed to improve dietary practices, reduce stress, and increase physical activity. Using a randomized controlled trial design with pretest-posttest comparisons within each group, 419 employees of a human resources company were randomly assigned to the Web-based condition or to a condition that provided print materials on the same topics. All subjects were assessed at pretest and posttest through an online questionnaire containing multiple measures of health behavior and attitudes. The test period was 3 months. Questionnaire data were analyzed mainly by analysis of covariance and t tests. Retention rates were good for both groups-85% for the Web-based group and 87% for the print group. Subjects using the Web-based program performed significantly better than the print group on Attitudes Toward a Healthful Diet (F(1,415) = 7.104, P = .008) and Dietary Stage of Change (F(1,408) = 6.487, P = .01), but there were no significant group differences on the five other dietary measures. Both groups also showed improvement from pretest to posttest on most dietary measures, as indicated by significant t tests. Within the Web-based group, dosage analyses showed significant effects of the number of times the subject accessed the program on measures of Dietary Self-Efficacy (F(2,203) = 5.270, P = .003), Attitudes Toward a Healthful Diet (F(2,204) = 2.585, P = .045), and Dietary Stage of Change (F(2,200) = 4.627, P = .005). No significant differences were found between the two groups on measures of stress or physical activity, although t tests of pretest-posttest changes indicated that both groups improved on several of these measures. The Web-based group gave significantly higher ratings to the program materials than the print group on all health topics and in their overall evaluation (F(1,410) = 9.808, P = .002). The Web-based program was more effective than print materials in producing improvements in the areas of diet and nutrition but was not more effective in reducing stress or increasing physical activity. The higher ratings given to the Web-based program suggest that workers preferred it to the print materials. Both groups showed numerous pretest-posttest improvements in all health topics, although such improvements might be attributable in part to a Hawthorne effect. Results suggest that a multimedia Web-based program can be a promising means of delivering health promotion material to the workforce, particularly in the area of diet and nutrition.

Within the Web-based group, dosage analyses showed significant effects of the number of times the subject accessed the program on measures of Dietary Self-Efficacy (F2,203 = 5.270, P = .003), Attitudes Toward a Healthful Diet (F2,204 = 2.585, P = .045), and Dietary Stage of Change (F2,200 = 4.627, P = .005). No significant differences were found between the two groups on measures of stress or physical activity, although t tests of pretest-posttest changes indicated that both groups improved on several of these measures. The Web-based group gave significantly higher ratings to the program materials than the print group on all health topics and in their overall evaluation (F1,410 = 9.808, P = .002). Conclusions The Web-based program was more effective than print materials in producing improvements in the areas of diet and nutrition but was not more effective in reducing stress or increasing physical activity. The higher ratings given to the Web-based program suggest that workers preferred it to the print materials. Both groups showed numerous pretest-posttest improvements in all health topics, although such improvements might be attributable in part to a Hawthorne effect. Results suggest that a multimedia Web-based program can be a promising means of delivering health promotion material to the workforce, particularly in the area of diet and nutrition. PMID:17581811

Gratitude intervention is expectedly an effective intervention to reduce depression and improve the quality of life in schizophrenic patients, but there is a lack of literature on it. We attempted to develop and test the effectiveness of the gratitude disposition promotion program for chronic schizophrenic patients in Korea. Nonequivalent control group pre- and post-test design was used in two mental health centers located at Gyeonggi-do in South Korea. This paper was a quasi-experimental study and the participants who took part in the gratitude disposition promotion program were 17 of experimental group and 15 of control group. Gratitude disposition (the short gratitude, resentment, and appreciation test), depression (Beck Depression Inventory), and quality of life (developed by Kook) of chronic schizophrenic patients were measured before and after an intervention, as compared to the control. Chi-square test, Fisher's exact test, and t -test were performed for prehomogeneity testing for variables related to the general characteristics. Testing for the effectiveness of gratitude disposition promotion program and hypothesis testing for its effect on depression and quality of life were by ANCOVA and t -test, as verified to significance level of P < 0.05. The participants who received the gratitude disposition promotion program showed significant improvements in gratitude disposition ( F = 18.740, P < 0.0001) and in quality of life ( F = 9.800, P = 0.004), but no significant difference in depression ( F = 3.870, P = 0.059). The gratitude disposition promotion program was an effective clinical intervention program for enhancing gratitude disposition and quality of life of chronic schizophrenic patients in community.

Fasching, W. A.

1980-01-01

The improved single shank high pressure turbine design was evaluated in component tests consisting of performance, heat transfer and mechanical tests, and in core engine tests. The instrumented core engine test verified the thermal, mechanical, and aeromechanical characteristics of the improved turbine design. An endurance test subjected the improved single shank turbine to 1000 simulated flight cycles, the equivalent of approximately 3000 hours of typical airline service. Initial back-to-back engine tests demonstrated an improvement in cruise sfc of 1.3% and a reduction in exhaust gas temperature of 10 C. An additional improvement of 0.3% in cruise sfc and 6 C in EGT is projected for long service engines.

To examine the cost and performance implications of introducing cell-free fetal DNA (cffDNA) testing within modeled scenarios in a publicly funded Canadian provincial Down syndrome (DS) prenatal screening program. Two clinical algorithms were created: the first to represent the current screening program and the second to represent one that incorporates cffDNA testing. From these algorithms, eight distinct scenarios were modeled to examine: (1) the current program (no cffDNA), (2) the current program with first trimester screening (FTS) as the nuchal translucency-based primary screen (no cffDNA), (3) a program substituting current screening with primary cffDNA, (4) contingent cffDNA with current FTS performance, (5) contingent cffDNA at a fixed price to result in overall cost neutrality,(6) contingent cffDNA with an improved detection rate (DR) of FTS, (7) contingent cffDNA with higher uptake of FTS, and (8) contingent cffDNA with optimized FTS (higher uptake and improved DR). This modeling study demonstrates that introducing contingent cffDNA testing improves performance by increasing the number of cases of DS detected prenatally, and reducing the number of amniocenteses performed and concomitant iatrogenic pregnancy loss of pregnancies not affected by DS. Costs are modestly increased, although the cost per case of DS detected is decreased with contingent cffDNA testing. Contingent models of cffDNA testing can improve overall screening performance while maintaining the provision of an 11- to 13-week scan. Costs are modestly increased, but cost per prenatally detected case of DS is decreased. © 2013 John Wiley & Sons, Ltd.

This paper aims to verify the efficacy of Cognitive Pragmatic Treatment (CPT), a new remediation training for the improvement of the communicative-pragmatic abilities, in patients with schizophrenia. The CPT program is made up of 20 group sessions, focused on a number of communication modalities, i.e., linguistic, extralinguistic and paralinguistic, theory of mind (ToM) and other cognitive functions able to play a role on the communicative performance, such as awareness and planning. A group of 17 patients with schizophrenia took part in the training program. They were evaluated before and after training, through the equivalent forms of the Assessment Battery for Communication (ABaCo), a tool for testing, both in comprehension and in production, a wide range of pragmatic phenomena such as direct and indirect speech acts, irony and deceit, and a series of neuropsychological and ToM tests. The results showed a significant improvement in patients’ performance on both production and comprehension tasks following the program, and in all the communication modalities evaluated through the ABaCo, i.e., linguistic, extralinguistic, paralinguistic, and social appropriateness. This improvement persisted after 3 months from the end of the training program, as shown by the follow-up tests. These preliminary findings provide evidence of the efficacy of the CPT program in improving communicative-pragmatic abilities in schizophrenic individuals. PMID:26941667

To increase adherence with intensive care unit mobility by developing and implementing a mobility training program that addresses nursing barriers to early mobilisation. An intensive care unit mobility training program was developed, implemented and evaluated with a pre-test, immediate post-test and eight-week post-test. Patient mobility was tracked before and after training. A ten bed cardiac intensive care unit. The training program's efficacy was measured by comparing pre-test, immediate post-test and 8-week post-test scores. Patient mobilisation rates before and after training were compared. Protocol compliance was measured in the post training group. Nursing knowledge increased from pre-test to immediate post-test (p<0.0001) and pre-test to 8-week post-test (p<0.0001). Mean test scores decreased by seven points from immediate post-test (80±12) to 8-week post-test (73±14). Fear significantly decreased from pre-test to immediate post-test (p=0.03), but not from pre-test to 8-week post-test (p=0.06) or immediate post-test to 8-week post-test (p=0.46). Post training patient mobility rates increased although not significantly (p=0.07). Post training protocol compliance was 78%. The project successfully increased adherence with intensive care unit mobility and indicates that a training program could improve adoption of early mobility. Copyright © 2016 Elsevier Ltd.

Tweed, Carol; Tweed, Mike

2008-07-01

Critically ill patients are at high risk for pressure ulcers. Successful prevention of pressure ulcers requires that caregivers have adequate knowledge of this complication. To assess intensive care nurses' knowledge of pressure ulcers and the impact of an educational program on knowledge levels. A knowledge assessment test was developed. A cohort of registered nurses in a tertiary referral hospital in New Zealand had knowledge assessed 3 times: before an educational program, within 2 weeks after the program, and 20 weeks later. Multivariate analysis was performed to determine if attributes such as length of time since qualifying or level of intensive care unit experience were associated with test scores. The content and results of the assessment test were evaluated. Completion of the educational program resulted in improved levels of knowledge. Mean scores on the assessment test were 84% at baseline and 89% following the educational program. The mean baseline score did not differ significantly from the mean 20-week follow-up score of 85%. No association was detected between demographic data and test scores. Content validity and standard setting were verified by using a variety of methods. Levels of knowledge to prevent and manage pressure ulcers were good initially and improved with an educational program, but soon returned to baseline.

The flight definition of the Variable Stream Control Engine (VSCE) was updated to reflect design improvements in the two key components: (1) the low emissions duct burner, and (2) the coannular exhaust nozzle. The testbed design was defined and plans for the overall program were formulated. The effect of these improvements was evaluated for performance, emissions, noise, weight, and length. For experimental large scale testing of the duct burner and coannular nozzle, a design definition of the VCE testbed configuration was made. This included selecting the core engine, determining instrumentation requirements, and selecting the test facilities, in addition to defining control system and assembly requirements. Plans for a comprehensive test program to demonstrate the duct burner and nozzle technologies were formulated. The plans include both aeroacoustic and emissions testing.

The feasibility of such intervention in chronic stroke survivors and its longer-term benefits, however, remain unknown. The objective of this pilot study was to estimate the short- and long-term effects of a 3-week piano training program on upper extremity function in persons with chronic stroke. A multiple pre-post sequential design was used, with measurements taken at baseline (week0, week3), prior to (week6) and after the intervention (week9), and at 3-week follow-up (week12). Three persons with stroke participated in the 3-week piano training program that combined structured piano lessons to home practice program. The songs, played on an electronic keyboard, involved all 5 digits of the affected hand and were displayed using a user-friendly MIDI program. After intervention, all the three participants showed improvements in their fine (nine hole peg test) and gross (box and block test) manual dexterity, as well as in the functional use of the upper extremity (Jebsen hand function test). Improvements were maintained at follow-up. These preliminary results support the feasibility of using an MST approach that combines structured lessons to home practice to improve upper extremity function in chronic stroke.

Forced spirometry is essential for diagnosing respiratory diseases and is widely used across levels of care. However, several studies have shown that spirometry quality in primary care is not ideal, with risks of misdiagnosis. Our objective was to assess the feasibility and performance of a telemedicine-based training and quality assurance program for forced spirometry in primary care. The two phases included (1) a 9-month pilot study involving 15 centers, in which spirometry tests were assessed by the Basque Office for Health Technology Assessment, and (2) the introduction of the program to all centers in the Public Basque Health Service. Technicians first received 4 h of training, and, subsequently, they sent all tests to the reference laboratory using the program. Quality assessment was performed in accordance with clinical guidelines (A and B, good; C-F, poor). In the first phase, 1,894 spirometry tests were assessed, showing an improvement in quality: acceptable quality tests increased from 57% at the beginning to 78% after 6 months and 83% after 9 months (p<0.001). In the second phase, 7,200 spirometry tests were assessed after the inclusion of 36 additional centers, maintaining the positive trend (61%, 87%, and 84% at the same time points; p<0.001). (1) The quality of spirometry tests improved in all centers. (2) The program provides a tool for transferring data that allows monitoring of its quality and training of technicians who perform the tests. (3) This approach is useful for improving spirometry quality in the routine practice of a public health system.

Aging is usually accompanied with deterioration of physical abilities, such as muscular strength, sensory sensitivity, and functional capacity. Recently, intervention methods with virtual reality have been introduced, providing an enjoyable therapy for elderly. The aim of this study was to investigate whether a 3-D virtual reality kayak program could improve the cognitive function, muscle strength, and balance of community-dwelling elderly. Importantly, kayaking involves most of the upper body musculature and needs the balance control. Seventy-two participants were randomly allocated into the kayak program group (n = 36) and the control group (n = 36). The two groups were well matched with respect to general characteristics at baseline. The participants in both groups performed a conventional exercise program for 30 min, and then the 3-D virtual reality kayak program was performed in the kayak program group for 20 min, two times a week for 6 weeks. Cognitive function was measured using the Montreal Cognitive Assessment. Muscle strength was measured using the arm curl and handgrip strength tests. Standing and sitting balance was measured using the Good Balance system. The post-test was performed in the same manner as the pre-test; the overall outcomes such as cognitive function (p < 0.05), muscle strength (p < 0.05), and balance (standing and sitting balance, p < 0.05) were significantly improved in kayak program group compared to the control group. We propose that the 3-D virtual reality kayak program is a promising intervention method for improving the cognitive function, muscle strength, and balance of elderly.

Falls are a common problem in older adults. Impaired balance, mobility and postural stability are risk factors for falling. Limited research has been performed on Pilates exercise and the ability to decrease fall risk. In this quasi-experimental study, 35 adults (61-87 years old) participated in an 8-week Pilates based exercise program. Blind examiners conducted the Timed Up and Go (TUG), Forward Reach Test, and Turn 180 Test before and after the intervention. Number of falls, perception of Pilates, and fear of falling was also recorded. Thirty-two (91.4%) participants completed post-test measures. Significant improvements were seen in the TUG (p <0.001) and Turn 180 Test (p = 0.002). Improvements were also demonstrated in the Forward Reach Test (p = 0.049). A positive perception of the Pilates program and decreased fear of falling was shown. Results suggest a Pilates based exercise program may be effective in improving balance, mobility and postural stability to decrease fall risk. Copyright © 2013 Elsevier Ltd. All rights reserved.

1978-01-01

A computer program for the application of parameter identification on the structural dynamic models of space shuttle and other large models with hundreds of degrees of freedom is described. Finite element, dynamic, analytic, and modal models are used to represent the structural system. The interface with math models is such that output from any structural analysis program applied to any structural configuration can be used directly. Processed data from either sine-sweep tests or resonant dwell tests are directly usable. The program uses measured modal data to condition the prior analystic model so as to improve the frequency match between model and test. A Bayesian estimator generates an improved analytical model and a linear estimator is used in an iterative fashion on highly nonlinear equations. Mass and stiffness scaling parameters are generated for an improved finite element model, and the optimum set of parameters is obtained in one step.

This article reports the outcomes of an evaluation conducted to determine if an academic skills training program for undergraduate predental students from underrepresented minority backgrounds increased the students' standardized academic skills test scores for vocabulary, reading comprehension, reading rates, spelling, and math as well as subject-specific test results in biology, chemistry, and physics. Data from standardized academic skill tests and subject-specific tests were collected at the beginning and end of the 1998 to 2006 Pipeline Programs, six-week summer enrichment programs for undergraduate predental students from disadvantaged backgrounds. In total, 179 students (75.4 percent African American, 7.3 percent Hispanic, 5.6 percent Asian American, 5 percent white) attended the programs during these nine summers. Scores on the Nelson-Denny Reading Test showed that the students improved their vocabulary scores (percentile ranks before/after: 46.80 percent/59.56 percent; p<.001), reading comprehension scores (47.21 percent/62.67 percent; p<.001), and reading rates (34.01 percent/78.31 percent; p<.001) from the beginning to the end of the summer programs. Results on the Wide Range Achievement Test III showed increases in spelling (73.58 percent/86.22 percent; p<.001) and math scores (56.98 percent/81.28 percent; p<.001). The students also improved their subject-specific scores in biology (39.07 percent/63.42 percent; p<.001), chemistry (20.54 percent/51.01 percent; p<.001), and physics (35.12 percent/61.14 percent; p<.001). To increase the number of underrepresented minority students in the dental school admissions pool, efforts are needed to prepare students from disadvantaged backgrounds for this process. These data demonstrate that a six-week enrichment program significantly improved the academic skills and basic science knowledge scores of undergraduate predental students. These improvements have the potential to enhance the performance of these students in college courses and thus increase their level of competitiveness in the dental school admissions process.

The aim of the present study was to investigate the effects of a short-term in-season plyometric training program on power, agility and knee extensor strength. Male soccer players from a third league team were assigned into an experimental and a control group. The experimental group, beside its regular soccer training sessions, performed a periodized plyometric training program for six weeks. The program included two training sessions per week, and maximal intensity unilateral and bilateral plyometric exercises (total of 40 – 100 foot contacts/session) were executed. Controls participated only in the same soccer training routine, and did not perform plyometrics. Depth vertical jump height, agility (Illinois Agility Test, T Agility Test) and maximal voluntary isometric torque in knee extensors using Multicont II dynamometer were evaluated before and after the experiment. In the experimental group small but significant improvements were found in both agility tests, while depth jump height and isometric torque increments were greater. The control group did not improve in any of the measures. Results of the study indicate that plyometric training consisting of high impact unilateral and bilateral exercises induced remarkable improvements in lower extremity power and maximal knee extensor strength, and smaller improvements in soccer-specific agility. Therefore, it is concluded that short-term plyometric training should be incorporated in the in-season preparation of lower level players to improve specific performance in soccer. PMID:23717351

To test the applicability of the Environmental Scoring System, a quick and simple approach for quantitatively measuring environmental triggers collected during home visits, and to evaluate its contribution to improving asthma outcomes among various child asthma programs. We pooled and analyzed data from multiple child asthma programs in the Greater Boston Area, Massachusetts, collected in 2011 to 2016, to examine the association of environmental scores (ES) with measures of asthma outcomes and compare the results across programs. Our analysis showed that demographics were important contributors to variability in asthma outcomes and total ES, and largely explained the differences among programs at baseline. Among all programs in general, we found that asthma outcomes were significantly improved and total ES significantly reduced over visits, with the total Asthma Control Test score negatively associated with total ES. Our study demonstrated that the Environmental Scoring System is a useful tool for measuring home asthma triggers and can be applied regardless of program and survey designs, and that demographics of the target population may influence the improvement in asthma outcomes.

The experimental group attended a program to improve self-management methods based on social cognitive theory (SCT). The program lasted 12 weeks, consisted of 1 1/2 hours meeting once a week, including group meetings and home visit monitoring. Mann-Whitney U test and Friedman test were employed to analyze the program's effectiveness. After the program, the mean rank of the perceived self-efficacy for the self-management strategies was statistically different between the two groups (p = 0.023). In the experimental group, after the twelve week, the mean rank of perceived self-efficacy and outcome expectancy increased and diastolic blood pressure decreased after the eight week. The program applied social cognitive theory (SCT) to promote self-management techniques, increased the health promoting behavior among hypertensive people.

This status paper reviews the experimental ground test program of the High Alpha Technology Program (HATP). The reasons for conducting this ground test program had their origins during the 1970's when several difficulties were experienced during the development programs of both the F-18 and F-16. A careful assessment of ground test to flight correlations appeared to be important for reestablishing a high degree of confidence in our ground test methodology. The current paper will then focus on one aspect of the HATP program that is intended to improve the correlation between ground test and flight, high-alpha gritting. The importance of this work arises from the sensitivity of configurations with smooth-sided forebodies to Reynolds number. After giving examples of the effects of Reynolds number, the paper will highlight efforts at forebody gritting. Finally, the paper will conclude by summarizing the charter of the HATP Experimental Aerodynamics Working Group and future experimental testing plans.

Engaging Community College Students Using an Engineering Learning Community

NASA Astrophysics Data System (ADS)

Maccariella, James, Jr.

The study investigated whether community college engineering student success was tied to a learning community. Three separate data collection sources were utilized: surveys, interviews, and existing student records. Mann-Whitney tests were used to assess survey data, independent t-tests were used to examine pre-test data, and independent t-tests, analyses of covariance (ANCOVA), chi-square tests, and logistic regression were used to examine post-test data. The study found students that participated in the Engineering TLC program experienced a significant improvement in grade point values for one of the three post-test courses studied. In addition, the analysis revealed the odds of fall-to-spring retention were 5.02 times higher for students that participated in the Engineering TLC program, and the odds of graduating or transferring were 4.9 times higher for students that participated in the Engineering TLC program. However, when confounding variables were considered in the study (engineering major, age, Pell Grant participation, gender, ethnicity, and full-time/part-time status), the analyses revealed no significant relationship between participation in the Engineering TLC program and course success, fall-to-spring retention, and graduation/transfer. Thus, the confounding variables provided alternative explanations for results. The Engineering TLC program was also found to be effective in providing mentoring opportunities, engagement and motivation opportunities, improved self confidence, and a sense of community. It is believed the Engineering TLC program can serve as a model for other community college engineering programs, by striving to build a supportive environment, and provide guidance and encouragement throughout an engineering student's program of study.

Implementation of the 80-hour work week has resulted in limitations on the hours available for resident education, creating a need for innovative approaches to teach surgical residents successfully. Herein we report the methods and results of an innovative didactic learning program at a large academic surgical residency program. Between 2004 and 2005, based on known principles of adult education and innovative learning techniques, a didactic learning program was instituted in a major academic surgery program. The course work consisted of a structured reading program using Schwartz's Textbook of Surgery, with weekly testing and problem-based learning (PBL) groups led by surgical faculty. The residents' progress was assessed by American Board of Surgery In-Training Examination (ABSITE) training scores before and after program implementation. A resident survey was also conducted to assess residents' attitudes toward the new program. Results were reported as a mean, and categoric variables were compared using a paired Student's t-test. During the academic year of the structured reading program, the mean ABSITE score improved by 10% (P=0.02) from the previous year. The postgraduate year 4 class had the largest change, with a score increase of 17% over the previous year's performance (P=0.02). Survey results demonstrated that 64% of the responders agreed that the small-group PBL was preferable for achieving educational goals. Furthermore, 89% of residents responded that the PBL groups improved interaction between residents and faculty members. An innovative formal learning program based on a major surgical textbook with weekly testing and small group sessions can significantly improve surgical training in the modern era of work-hour restrictions. Furthermore, surgical trainees find this format to be innovative and useful for improving didactic teaching.

The objective of this applied research effort led by Georgia Tech Research Institute is the application of pneumatic aerodynamic technology previously developed and patented by us to the design of an appropriate Heavy Vehicle (HV) tractor-trailer configuration, and experimental confirmation of this pneumatic configuration's improved aerodynamic characteristics. In Phases I to IV of our previous DOE program (Reference 1), GTRI has developed, patented, wind-tunnel tested and road-tested blown aerodynamic devices for Pneumatic Heavy Vehicles (PHVs) and Pneumatic Sports Utility Vehicles (PSUVs). To further advance these pneumatic technologies towards HV and SUV applications, additional Phase V tasks were included in themore » first year of a continuing DOE program (Reference 2). Based on the results of the Phase IV full-scale test programs, these Phase V tasks extended the application of pneumatic aerodynamics to include: further economy and performance improvements; increased aerodynamic stability and control; and safety of operation of Pneumatic HVs. Continued development of a Pneumatic SUV was also conducted during the Phase V program. Phase V was completed in July, 2003; its positive results towards development and confirmation of this pneumatic technology are reported in References 3 and 4. The current Phase VI of this program was incrementally funded by DOE in order to continue this technology development towards a second fuel economy test on the Pneumatic Heavy Vehicle. The objectives of this current Phase VI research and development effort (Ref. 5) fall into two categories: (1) develop improved pneumatic aerodynamic technology and configurations on smaller-scale models of the advanced Pneumatic Heavy Vehicle (PHV); and based on these findings, (2) redesign, modify, and re-test the modified full-scale PHV test vehicle. This second objective includes conduct of an on-road preliminary road test of this configuration to prepare it for a second series of SAE Type-U fuel economy evaluations, as described in Ref. 5. Both objectives are based on the pneumatic technology already developed and confirmed for DOE OHVT/OAAT in Phases I-V. This new Phase VI effort was initiated by contract amendment to the Phase V effort using carryover FY02 funds. This were conducted under a new and distinct project number, GTRI Project A-6935, separate from the Phase I-IV program. However, the two programs are closely integrated, and thus Phase VI continues with the previous program and goals.« less

Work performed by the McDonnell Douglas Helicopter Company and Lucas Western, Inc. within the U.S. Army/NASA Advanced Rotorcraft Transmission (ART) Program is summarized. The design of a 5000 horsepower transmission for a next generation advanced attack helicopter is described. Government goals for the program were to define technology and detail design the ART to meet, as a minimum, a weight reduction of 25 percent, an internal noise reduction of 10 dB plus a mean-time-between-removal (MTBR) of 5000 hours compared to a state-of-the-art baseline transmission. The split-torque transmission developed using face gears achieved a 40 percent weight reduction, a 9.6 dB noise reduction and a 5270 hour MTBR in meeting or exceeding the above goals. Aircraft mission performance and cost improvements resulting from installation of the ART would include a 17 to 22 percent improvement in loss-exchange ratio during combat, a 22 percent improvement in mean-time-between-failure, a transmission acquisition cost savings of 23 percent of $165K, per unit, and an average transmission direct operating cost savings of 33 percent, or $24K per flight hour. Face gear tests performed successfully at NASA Lewis are summarized. Also, program results of advanced material tooth scoring tests, single tooth bending tests, Charpy impact energy tests, compact tension fracture toughness tests and tensile strength tests are summarized.

Context: Gratitude intervention is expectedly an effective intervention to reduce depression and improve the quality of life in schizophrenic patients, but there is a lack of literature on it. Aims: We attempted to develop and test the effectiveness of the gratitude disposition promotion program for chronic schizophrenic patients in Korea. Settings and Design: Nonequivalent control group pre- and post-test design was used in two mental health centers located at Gyeonggi-do in South Korea. Materials and Methods: This paper was a quasi-experimental study and the participants who took part in the gratitude disposition promotion program were 17 of experimental group and 15 of control group. Gratitude disposition (the short gratitude, resentment, and appreciation test), depression (Beck Depression Inventory), and quality of life (developed by Kook) of chronic schizophrenic patients were measured before and after an intervention, as compared to the control. Statistical Analysis: Chi-square test, Fisher's exact test, and t-test were performed for prehomogeneity testing for variables related to the general characteristics. Testing for the effectiveness of gratitude disposition promotion program and hypothesis testing for its effect on depression and quality of life were by ANCOVA and t-test, as verified to significance level of P < 0.05. Results: The participants who received the gratitude disposition promotion program showed significant improvements in gratitude disposition (F = 18.740, P < 0.0001) and in quality of life (F = 9.800, P = 0.004), but no significant difference in depression (F = 3.870, P = 0.059). Conclusions: The gratitude disposition promotion program was an effective clinical intervention program for enhancing gratitude disposition and quality of life of chronic schizophrenic patients in community.

Purpose: Treatment unit uptime statistics are typically used to monitor radiation equipment performance. The Ottawa Hospital Cancer Centre has introduced the use of Quality Control (QC) test success as a quality indicator for equipment performance and overall health of the equipment QC program. Methods: Implemented in 2012, QATrack+ is used to record and monitor over 1100 routine machine QC tests each month for 20 treatment and imaging units ( http://qatrackplus.com/ ). Using an SQL (structured query language) script, automated queries of the QATrack+ database are used to generate program metrics such as the number of QC tests executed and themore » percentage of tests passing, at tolerance or at action. These metrics are compared against machine uptime statistics already reported within the program. Results: Program metrics for 2015 show good correlation between pass rate of QC tests and uptime for a given machine. For the nine conventional linacs, the QC test success rate was consistently greater than 97%. The corresponding uptimes for these units are better than 98%. Machines that consistently show higher failure or tolerance rates in the QC tests have lower uptimes. This points to either poor machine performance requiring corrective action or to problems with the QC program. Conclusions: QATrack+ significantly improves the organization of QC data but can also aid in overall equipment management. Complimenting machine uptime statistics with QC test metrics provides a more complete picture of overall machine performance and can be used to identify areas of improvement in the machine service and QC programs.« less

To develop, implement, and evaluate the effects of a school-based asthma educational program on Saudi primary school teachers' asthma awareness and competence in delivering asthma-related first aid interventions. An asthma educational intervention program entitled "School Asthma Action Program" (SAAP) was designed based on pedagogical principles and implemented among teachers randomly selected from girls' primary schools in Riyadh, Saudi Arabia. This pilot study employed a pre-test/post-test experimental design. A previously tested asthma awareness questionnaire and a custom-designed asthma competence score sheet were used to evaluate the effects of the educational intervention program on teacher's asthma awareness and competence in providing asthma-related first aid interventions at schools. Forty-seven teachers from five different primary schools participated in the program. Of the 47 teachers, 39 completed both the pre- and post-program questionnaires. The SAAP improved teachers' awareness of asthma (teachers' median pre-program score was 11 (range 5-18) and their post-program score was 15 (range 7-18), p < 0.001) and their attitudes toward asthma management at schools (teachers' median pre-program score was 74 (range 15-75) and their post-program score was 75 (range 15-75), p = 0.043). Further, it improved teachers' competence in providing asthma-related first aid interventions (teachers' mean pre-program score was 1.4 ± 2.3 and their mean post-program score was 9.8 ± 0.5, p < 0.001). After completing the SAAP, a high proportion of teachers reported increased confidence in providing care to children with asthma at school. School-based asthma educational programs can significantly improve teachers' knowledge of asthma and their competence in providing asthma-related first aid interventions during emergencies.

A systematic review by Barclay-Goddard et al (2004) reported that force platform feedback improved stance symmetry but not sway, clinical balance outcomes, or measures of independence in adults with stroke. However, the role of computerized dynamic posturography (CDP) systems was not explored. The purpose of this case report was to describe a CDP training program to improve balance and reduce fall risk in a patient with a diagnosis of chronic stroke. A 61-year-old patient 8 years poststroke participated in 1 hour of CDP training, three times a week over a period of 6 weeks. Examination was conducted before and after intervention using the Sensory Organization Test (SOT), Limits of Stability (LOS) test, and Weight Bearing/Squat Symmetry test on a CDP system, and clinical testing with the Berg Balance Scale (BBS), Timed Up and Go (TUG), Activities-specific Balance Confidence (ABC) scale, 30-second Chair Stand (CS), and range of motion of the ankle joints. The patient improved in sensory integration abilities on the SOT for conditions 4, 5, and 6, and maximum excursion abilities improved by a range of 23-103% on the LOS test. Scores on the BBS increased from 37/56 to 47/56, which indicated reduced fall risk and her ABC score improved from 50% to 70%. Ankle ROM improved bilaterally by 6 to 8 degrees. This CDP training program showed promise as a systematic, objective method to reduce fall risk with improved overground performance of balance tasks in an individual with chronic stroke.

This study was conducted to develop and test the effects of an emotional intelligence program for undergraduate nursing students. The study design was a mixed method research. Participants were 36 nursing students (intervention group: 17, control group: 19). The emotional intelligence program was provided for 4 weeks (8 sessions, 20 hours). Data were collected between August 6 and October 4, 2013. Quantitative data were analyzed using Chi-square, Fisher's exact test, t-test, repeated measure ANOVA, and paired t-test with SPSS/WIN 18.0. Qualitative data were analyzed using content analysis. Quantitative results showed that emotional intelligence, communication skills, resilience, stress coping strategy, and clinical competence were significantly better in the experimental group compared to the control group. According to the qualitative results, the nursing students experienced improvement in emotional intelligence, interpersonal relationships, and empowerment, as well as a reduction in clinical practice stress after participation in the emotional intelligence program. Study findings indicate that the emotional intelligence program for undergraduate nursing students is effective and can be recommended as an intervention for improving the clinical competence of undergraduate students in a nursing curriculum.

The Planning and Implementation of Test Facility Improvements

NASA Technical Reports Server (NTRS)

Oberlander, Larry

2008-01-01

As engineering programs develop, and product testing begins, ideas for process improvement soon become obvious. Engineers envision new holding and handling fixtures. Additional custom-made support equipment may be needed. Perhaps modifications to the building or modifications to facility hardware are the order of the day. This is where a flexible creative test organization is needed. We need not be content with the status quo. All of these desired test innovations can make the difficult easy and improve the work flow. At times, implementing these new ideas demands more time or specialized expertise than test team members have. Through the coordinated use of labor resources, the needed improvements can still be made and in a timely fashion that supports program schedules. This presentation provides practical advice and a method whereby test personnel can creatively develop facility improvements and manage them from start to finish. You can control just how much time you invest and what part of your concepts you will personally design. By wisely defining the requirements and presenting them to the appropriate help sources (vendors, contractors, coworkers, and support departments), you can get the help you need to bring the improvements you have conceived, into fruition. Aspects of this presentation include defining requirements for test facility improvements, choosing labor resources, writing a statement of work, determining cost and benefits, securing department approval, coordinating procurement, managing the project, and training the end users. The process of successfully implementing test facility improvements is thoroughly explained. It has been tried, proven and improved over nearly 25 years of use. Whether considering a $50 improvement or a $50 million dollar improvement, this discussion will provide helpful pointers. Examples of improvements made through this process and their illustration will be included.

The purpose of this study was to determine if combining velocity-based training with eccentric focus (VEB) and velocity-based training (VBT) results in power and strength gains. Nineteen men and women collegiate track and field athletes participated in this study. The subjects completed a 12-week intervention with either a VEB program or a VBT program. To determine the effectiveness of each program, the subjects completed four exercise tests before and after the training period: vertical jump, medicine ball put test, 1RM projected bench press and 1RM projected squat. There were no significant differences between the VBT results and the VEB results. However, there were significant improvements between the pre-test and post-test measures for each group. There were increases in 1RM projected squat for VEB men, VBT men, and VBT women. There were also significant improvements in the VEB male vertical jump and medicine ball put test pre- to post-intervention. For track and field athletes, both programs may result in strength and power gains, however, the results cannot be used to conclude that one resistance training program is superior. PMID:27990226

Review of Interventions to Improve Family Engagement and Retention in Parent and Child Mental Health Programs

PubMed Central

2010-01-01

Engaging and retaining families in mental health prevention and intervention programs is critically important to insure maximum public health impact. We evaluated randomized-controlled trials testing methods to improve family engagement and retention in child mental health programs published since 1980 (N = 17). Brief, intensive engagement interventions in which providers explicitly addressed families’ practical (e.g. schedules, transportation) and psychological (e.g. family members’ resistance, beliefs about the treatment process) barriers as they entered treatment were effective in improving engagement in early sessions. The few interventions found to produce long-term impact on engagement and retention integrated motivational interviewing, family systems, and enhanced family stress and coping support strategies at multiple points throughout treatment. Few interventions have been tested in the context of prevention programs. There are promising approaches to increasing engagement and retention; they should be replicated and used as a foundation for future research in this area. PMID:20823946

To assess the immediate effect on trauma-related knowledge of the trauma evaluation and management (TEAM) program applied to medical students in Australia. 73 final year medical students from Melbourne were randomly assigned to two experimental groups (E1 and E2 who completed the TEAM program after a 20 item MCQ pre-test on trauma resuscitation and a second MCQ exam after the TEAM program) and two control groups (C1 and C2 who completed the pre- and post-MCQ exams before completing the TEAM module). All 73 students completed an evaluation questionnaire. Paired and unpaired t-tests were used for within and between groups comparisons. Groups C1 and C2 had similar mean scores in pre- and post-tests ranging from 57.2 to 60.5%. Groups E1 and E2 had similar pre-test scores but increased their post-test scores (pre-test range 53.8-57.1% and post-test 68.8-77.4%, P < 0.05). On a scale of 1-5 with five being the highest, a score of four or greater was assigned by over 74% of the students that the objectives were met, over 80% that trauma knowledge was improved, 25-40% that clinical skills were improved with over 74% overall satisfaction. Over 75% assigned a score of four or greater suggesting the module be mandatory. After the TEAM program there was significant improvement in cognitive skills. The students strongly supported its introduction in the undergraduate curriculum.

Functional training improves club head speed and functional fitness in older golfers.

Thompson, Christian J; Cobb, Karen Myers; Blackwell, John

2007-02-01

Functional training programs have been used in a variety of rehabilitation settings with documented success. Based on that success, the concept of functional training has gained popularity in applied fitness settings to enhance sport performance. However, there has been little or no research studying the efficacy of functional training programs on the improvement of sport performance or functional fitness. Thus, it was the purpose of this study to determine the effect of a progressive functional training program on club head speed and functional fitness in older male golfers. Eighteen male golfers (age: 70.7 +/- 9.1 [SD] years) were randomly assigned to an exercise (N = 11) or control (N = 7) group. The exercise group participated in an 8-week progressive functional training program including flexibility exercises, core stability exercises, balance exercises, and resistance exercises. Pre- and postmeasurements included club head speed of a driver by radar (exercise and Control) and Fullerton Senior Fitness Test measurements (exercise only). One-way analysis of covariance was performed on club head speed measurements using pretest measurements as the covariate. Paired t-tests were performed to analyze Senior Fitness Test variables. After the intervention, maximal club head speed increased in the exercise group (127.3 +/- 13.4 to 133.6 +/- 14.2 km x hr(-1)) compared with the control group (134.5 +/- 14.6 to 133.3 +/- 11.2 km x hr(-1); p < 0.05). Additionally, improvements (p < 0.05) were detected for most Senior Fitness Test variables in the exercise group. In summary, this functional training program resulted in significant improvements in club head speed and several components of functional fitness. Future research should continue to examine the effect of functional training programs on sport performance and functional fitness in older adults.

A short history is traced of the work done at Sikorsky Aircraft under the NASA/industry DAMVIBS program. This includes both work directly funded by the program as well as work which was internally funded but which received its initial impetus from DAMVIBS. The development of a finite element model of the UH-60A airframe having a marked improvement in vibration-predicting ability is described. A new program, PAREDYM, developed at Sikorsky, which automatically adjusts an FEM so that its modal characteristics match test values, is described, as well as the part this program played in the improvement of the UH-60A model. Effects of the bungee suspension system on the shake test data used for model verification are described. The impetus given by the modeling improvement, as well as the recent availability of PAREDYM, has brought for the first time the introduction of low-vibration design into the design cycle at Sikorsky.

Facilitating aerobic exercise training in older adults with Alzheimer's disease.

PubMed

Yu, Fang; Kolanowski, Ann

2009-01-01

Emerging science suggests that aerobic exercise might modify the pathophysiology of Alzheimer's disease (AD) and improve cognition. However, there are no clinical practice guidelines for aerobic exercise prescription and training in older adults with AD. A few existing studies showed that older adults with AD can participate in aerobic exercise and improve dementia symptoms, but lack adequate descriptions of their aerobic exercise training programs and their clinical applicability. In this paper, we summarize current knowledge about the potential benefits of aerobic exercise in older adults with AD. We then describe the development of a moderate-intensity aerobic exercise program for this population and report results from its initial testing in a feasibility trial completed by two persons with AD. Two older adults with AD completed the aerobic exercise program. Barriers to the program's implementation are described, and methods to improve more wide-spread adoption of such programs and the design of future studies that test them are suggested.

Testing the theories that form the basis of prevention programs can enhance our understanding of behavioral change and inform the development, coordination, and adaptation of prevention programs. However, theories of change showing the linkages from intervention program components to risk or protective factors to desired outcomes across time are rarely specified or tested. In this 2-year longitudinal study, we test the theory that increases in two protective factors (i.e., children's prosocial leadership and their teachers' expectations of social responsibility) targeted by the WITS Programs (Walk Away, Ignore, Talk it Out, and Seek Help) would be associated with declines in peer victimization, aggression, and emotional problems. Participants included Canadian students, in grades 1-4 at baseline (n = 1329) and their parents and teachers. Consistent with our theory of change, variability in program implementation (adherence and integration) and in children's use of program skills (child responsiveness) are related to increases in both protective factors. Increases in these protective factors are associated with subsequent declines in children's aggression, victimization, and emotional problems. We discuss how enhancement of these protective factors may operate to improve child outcomes and the need for theory-based research to refine and improve the effectiveness of intervention strategies and to improve program scale-up. © Society for Community Research and Action 2016.

Pressure ulcers are a common complication of spinal cord injury (SCI). Pressure ulcer education programs for spinal cord injured individuals have been found to have a positive effect on care protocol adherence. A prospective study was conducted among hospitalized spinal cord-injured men and women to determine if viewing the Pressure Ulcer Prevention and Management Education for Adults with Spinal Cord Injury: E-Learning Program affects their knowledge scores. A 20-question multiple-choice pre-/post learning test was developed and validated by 12 rehabilitation nurses. Twenty (20) patients (13 men, seven women; mean age 49 years, [SD: 18.26] with injuries to the cervical [seven], thoracic [six], and lumbar [six] regions) volunteered. Most (42%) had completed high school and time since SCI ranged from 2 weeks to 27 years. Eighteen (18) participants completed both the pre- and post test. Of those, 16 showed improvement in pressure ulcer knowledge scores. The median scores improved from 65 (range 25 to 100) pre-program to 92.5 (range 75 to 100) post-program. Descriptive statistics, Student's t-test, and analysis of variance (ANOVA) were used to analyze the data. The results suggest that a single viewing of this e-learning program could improve pressure ulcer knowledge of hospitalized adults with SCI. Research to ascertain the effects of this and other educational programs on pressure ulcer rates is needed.

The purpose of this study was to determine the effects of smartphone apps applying BodyThink program on BMI, percentage of body fat, skeletal muscle rate, body image, and self-esteem of adolescent girls. Sixty-eight high school girls with a BMI of over 25kg/m² were recruited to participate in this study. Girls from four schools were divided into two groups: the experimental group, which used the smartphone apps applying BodyThink program, and the control group, which used smartphone apps and small group counseling. The experimental group received the BodyThink program 6 times, scheduled once a week, with each session lasting 40~50 minutes. Test measures were completed before and after the 6 week intervention period for all participants. Collected data was analyzed using Shapiro-Wilk test, descriptive statistics, χ² test, independent t-test, Mann-Whitney U test with the SPSS/WIN 18.0 program. The girls in the experimental group significantly improved their results in BMI(Z=-1.67, p=.042), percentage of body fat (Z=-3.01, p=.001), skeletal muscle rate (t=-3.50, p<.001), and self-esteem (t=2.66, p=.005) after the program, compared to the girls in the control group. Mobile applications applying psychological and emotional intervention programs have the potential to be effective alternative methods to improve the body composition and self-esteem of obese adolescent girls.

To assess knowledge improvement by the participants in a pharmacist-facilitated national community education program over a 4-month semester and to identify the educational needs of adults related to medications. This was a single-group, pre- and post-program comparative study. From February 2005 to February 2006, 1983 community residents participating in the education program implemented at 57 community universities nationwide were included. A questionnaire consisting of 50 true/false questions was administered before and after the program to assess the participants' medication knowledge. Paired t test was used to analyze the pre- and post-program differences and generalized linear mixed models were applied to examine the demographic variables that might influence the background knowledge and outcome after adjusting for school effects. A total of 848 participants (42.8%) completed the pre-to-post questionnaire. Baseline medication knowledge was positively correlated with participants' education level and negatively correlated with age. Significant improvement (11.3%, p < 0.001) in medication knowledge was evident at the end of the program. The age and education level were significant determinants in the improvement of the pre-to-post program test score. The specific areas that required improvement most in the knowledge of the participants were: instructions on refill prescriptions, proper storage of medication, the health insurance system, drug use in special populations, and over-the-counter drugs. This national program improved participants' medication knowledge over a 4-month period. Patient counseling focusing more on the knowledge deficiency identified in this study during patient care is recommended. Copyright © 2015. Published by Elsevier B.V.

Stroke remains the leading cause of acquired disability. Health and social planning and management may vary and although prevention is crucial, having better treatments and strategies to reduce disability is needed. To determine the effect of an intensive program of thalassotherapy and aquatic therapy in stroke patients, valuing clinical parameters and functional validated scales. A quasi-experimental prospective study consisting of a specific program assessed pre- and post- 3 weeks treatment to 26 stroke patients with a mild-moderate disability. The outcomes measured were: Berg Balance scale, Timed Up and Go test, 10-meter walking test, 6-minute walking test and pain Visual Analogue Scale. After intervention, participants had a significant improvement in all outcomes measured. Our results suggest that an intensive program of thalassotherapy and aquatic therapy could be useful during stroke rehabilitation to improve balance, gait and pain.

Dance performance requires not only lower extremity muscle strength and endurance, but also sufficient core stabilization during dynamic dance movements. While previous studies have identified a link between core muscle performance and lower extremity injury risk, what has not been determined is if an extended core stabilization training program will improve specific measures of dance performance. This study examined the impact of a nine-week core stabilization program on indices of dance performance, balance measures, and core muscle performance in competitive collegiate dancers. Within-subject repeated measures design. A convenience sample of 24 female collegiate dance team members (age = 19.7 ± 1.1 years, height = 164.3 ± 5.3 cm, weight 60.3 ± 6.2 kg, BMI = 22.5 ± 3.0) participated. The intervention consisted of a supervised and non-supervised core (trunk musculature) exercise training program designed specifically for dance team participants performed three days/week for nine weeks in addition to routine dance practice. Prior to the program implementation and following initial testing, transversus abdominis (TrA) activation training was completed using the abdominal draw-in maneuver (ADIM) including ultrasound imaging (USI) verification and instructor feedback. Paired t tests were conducted regarding the nine-week core stabilization program on dance performance and balance measures (pirouettes, single leg balance in passe' releve position, and star excursion balance test [SEBT]) and on tests of muscle performance. A repeated measures (RM) ANOVA examined four TrA instruction conditions of activation: resting baseline, self-selected activation, immediately following ADIM training and four days after completion of the core stabilization training program. Alpha was set at 0.05 for all analysis. Statistically significant improvements were seen on single leg balance in passe' releve and bilateral anterior reach for the SEBT (both p ≤ 0.01), number of pirouettes (p = 0.011), and all measures of strength (p ≤ 0.05) except single leg heel raise. The RM ANOVA on mean percentage of change in TrA was significant; post hoc paired t tests demonstrated significant improvements in dancers' TrA activations across the four instruction conditions. This core stabilization training program improves pirouette ability, balance (static and dynamic), and measures of muscle performance. Additionally, ADIM training resulted in immediate and short-term (nine-week) improvements in TrA activation in a functional dance position. 2b.

Improving functional mobility is often a desired outcome for adolescents with cerebral palsy (CP). Traditional neurorehabilitation approaches are frequently directed at impairments; however, improvements may not be carried over into functional mobility. The purpose of this case report was to describe the examination, intervention, and outcomes of a task-oriented physical therapy intervention program to improve dynamic balance, functional mobility, and dual-task performance in an adolescent with CP. The participant was a 15-year-old girl with spastic triplegic CP (Gross Motor Classification System Level II). Examination procedures included the Canadian Occupational Performance Measure, 6-minute walk test, Muscle Power Sprint Test, 10 x 5-meter sprint test, Timed Up and Down Stairs Test, Gross Motor Function Measure, Gillette Functional Assessment Questionnaire, and functional lower extremity strength tests. Intervention focused on task-oriented dynamic balance and mobility tasks that incorporated coordination and speed demands as well as task-specific lower extremity and trunk strengthening activities. Dual task demands were integrated into all intervention activities. Post-intervention testing revealed improvements in cardiovascular endurance, anaerobic power, agility, stair climbing, gross motor skills, and mobility. The participant appeared to benefit from a task-oriented program to improve dynamic balance, functional mobility, and dual-task performance.

Development and pilot testing of a disease management program for low literacy patients with heart failure. Randomized trials have shown that disease management programs can reduce hospitalizations and improve symptoms for patients with congestive heart failure. We sought to create and pilot test such a program for patients with low literacy skills. We used focus groups and individual cognitive response interviews (CRIs) to develop an educational booklet for low literacy patients with heart failure. We incorporated the booklet into a disease management intervention that also included an initial individualized 1-h educational session and scheduled supportive phone calls that were tapered over 6 weeks. We then conducted a 3-month before-after study on patients with low literacy skills (<9th grade literacy level) in a university internal medicine clinic to test the acceptability and efficacy of our program. Outcomes of interest included heart failure-related knowledge, self-care behavior and heart failure-related symptoms measured on the Minnesota Living with Heart Failure (MLwHF) scale. Twenty-five patients were enrolled and 23 (92%) completed 3-month follow-up. Mean age was 60 years (range 35-74), 60% were men, 60% were African-American, and 74% had household income under $15,000 per year. The median reading level was fifth grade with 32% reading at or below the third grade level. Mean knowledge score at baseline was 67% and did not improve after the intervention. The proportion of patients reporting weighing themselves daily increased from 32% at baseline to 100% at 12 weeks. Mean improvement on the MLwHF scale was 9.9 points over the 3-month trial (95% CI: 0.5, 19.2), which corresponds to an improvement in one class on the New York Heart Association heart failure scale. A heart failure disease management program designed specifically for patients with low literacy skills is acceptable and is associated with improvement in self-care behavior and heart failure related symptoms.

Physical activity can prevent or delay the onset of physical functional limitations in older adults. There are limited data that evidence-based physical activity interventions can be successfully translated into community programs and result in similar benefits for physical functioning. The purpose of this study is to measure the effects of the Active Living Every Day program on physical functioning and physical functional limitations in a diverse sample of older adults. As a part of the Active for Life initiative, the Council on Aging of Southwestern Ohio implemented Active Living Every Day (ALED), a group-based lifestyle behavior change program designed to increase physical activity. Performance-based physical functioning tests (30-s Chair Stand Test, eight Foot Up-and-Go Test, Chair Sit-and-Reach Test, 30-Foot Walk Test) were administered to participants at baseline and posttest. Baseline to post-program changes in physical functioning and impairment status were examined with repeated measures analysis of covariance. Interactions tested whether change over time differed according to race/ethnicity, body mass index (BMI), and baseline impairment status. Participants significantly increased their performance in all four physical functioning tests. The percentage of participants classified as "impaired" according to normative data significantly decreased over time. Physical functioning improved regardless of BMI, race/ethnicity, or baseline impairment status. ALED is an example of an evidenced-based physical activity program that can be successfully translated into community programs and result in significant and clinically meaningful improvements in performance-based measures of physical functioning.

This study investigated the effects of a novel, classroom-based emotion self-regulation program (TestEdge) on measures of test anxiety, socioemotional function, test performance, and heart rate variability (HRV) in high school students. The program teaches students how to self-generate a specific psychophysiological state--psychophysiological coherence--which has been shown to improve nervous system function, emotional stability, and cognitive performance. Implemented as part of a larger study investigating the population of tenth grade students in two California high schools (N = 980), the research reported here was conducted as a controlled pre- and post-intervention laboratory experiment, using electrophysiological measures, on a random stratified sample of students from the intervention and control schools (N = 136). The Stroop color-word conflict test was used as the experiment's stimulus to simulate the stress of taking a high-stakes test, while continuous HRV recordings were gathered. The post-intervention electrophysiological results showed a pattern of improvement across all HRV measures, indicating that students who received the intervention program had learned how to better manage their emotions and to self-activate the psychophysiological coherence state under stressful conditions. Moreover, students with high test anxiety exhibited increased HRV and heart rhythm coherence even during a resting baseline condition (without conscious use of the program's techniques), suggesting that they had internalized the benefits of the intervention. Consistent with these results, students exhibited reduced test anxiety and reduced negative affect after the intervention. Finally, there is suggestive evidence from a matched-pairs analysis that reduced test anxiety and increased psychophysiological coherence appear to be directly associated with improved test performance--a finding consistent with evidence from the larger study.

Design of experiments enhanced statistical process control for wind tunnel check standard testing

NASA Astrophysics Data System (ADS)

Phillips, Ben D.

The current wind tunnel check standard testing program at NASA Langley Research Center is focused on increasing data quality, uncertainty quantification and overall control and improvement of wind tunnel measurement processes. The statistical process control (SPC) methodology employed in the check standard testing program allows for the tracking of variations in measurements over time as well as an overall assessment of facility health. While the SPC approach can and does provide researchers with valuable information, it has certain limitations in the areas of process improvement and uncertainty quantification. It is thought by utilizing design of experiments methodology in conjunction with the current SPC practices that one can efficiently and more robustly characterize uncertainties and develop enhanced process improvement procedures. In this research, methodologies were developed to generate regression models for wind tunnel calibration coefficients, balance force coefficients and wind tunnel flow angularities. The coefficients of these regression models were then tracked in statistical process control charts, giving a higher level of understanding of the processes. The methodology outlined is sufficiently generic such that this research can be applicable to any wind tunnel check standard testing program.

To assess the feasibility and safety of a 6-week course of water walking performed using a motorized aquatic treadmill in individuals with subacute stroke for cardiorespiratory fitness, walking endurance, and activities of daily living. Twenty subacute stroke patents were randomly assigned to aquatic treadmill exercise (ATE) or land-based exercise (LBE). The ATE group (n = 10) performed water-based aerobic exercise on a motorized aquatic treadmill, and the LBE group (n = 10) performed land-based aerobic exercise on a cycle ergometer. Both groups performed aerobic exercise for 30 minutes, 5 times per week for 6 weeks. Primary outcome measures were 6-minute walk test for walking endurance and cardiopulmonary fitness parameters of a symptom-limited exercise tolerance test, and secondary measures were Korean version of the Modified Barthel Index (K-MBI) for activities of daily living. All variables were assessed at baseline and at the end of the intervention. The ATE group showed significant improvements in 6-minute walk test (P = .005), peak oxygen uptake (V·o2peak; P = .005), peak heart rate (P = .007), exercise tolerance test duration (P = .005), and K-MBI (P = .008). The LBE group showed a significant improvement only in K-MBI (P = .012). In addition, improvement in V·o2peak was greater in the ATE than in the LBE group. This preliminary study showed that a 6-week ATE program improved peak aerobic capacity and walking endurance in patients with subacute stroke. The improvement in V·o2peak after an ATE exercise program was greater than that observed after an LBE program. Therefore, ATE effectively improves cardiopulmonary fitness in patients with subacute stroke.

This study compared the effectiveness of three approaches to improving visual perception among preschool children 4-6 years old with developmental delays: multimedia visual perceptual group training, multimedia visual perceptual individual training, and paper visual perceptual group training. A control group received no special training. This study employed a pretest-posttest control group of true experimental design. A total of 64 children 4-6 years old with developmental delays were randomized into four groups: (1) multimedia visual perceptual group training (15 subjects); (2) multimedia visual perceptual individual training group (15 subjects); paper visual perceptual group training (19 subjects); and (4) a control group (15 subjects) with no visual perceptual training. Forty minute training sessions were conducted once a week for 14 weeks. The Test of Visual Perception Skills, third edition, was used to evaluate the effectiveness of the intervention. Paired-samples t-test showed significant differences pre- and post-test among the three groups, but no significant difference was found between the pre-test and post-test scores among the control group. ANOVA results showed significant differences in improvement levels among the four study groups. Scheffe post hoc test results showed significant differences between: group 1 and group 2; group 1 and group 3; group 1 and the control group; and group 2 and the control group. No significant differences were reported between group 2 and group 3, and group 3 and the control group. The results showed all three therapeutic programs produced significant differences between pretest and posttest scores. The training effect on the multimedia visual perceptual group program and the individual program was greater than the developmental effect Both the multimedia visual perceptual group training program and the multimedia visual perceptual individual training program produced significant effects on visual perception. The multimedia visual perceptual group training program was more effective for improving visual perception than was multimedia visual perceptual individual training program. The multimedia visual perceptual group training program was more effective than was the paper visual perceptual group training program. Copyright © 2013 Elsevier Ltd. All rights reserved.

Most women with perinatal depression do not receive depression treatment. The authors describe the development and beta testing of a new program, PRogram In Support of Moms (PRISM), to improve treatment of perinatal depression in obstetric practices. A multidisciplinary work group of seven perinatal and behavioral health professionals was convened to design, refine, and beta-test PRISM in an obstetric practice. Iterative feedback and problem solving facilitated development of PRISM components, which include provider training and a toolkit, screening procedures, implementation assistance, and access to immediate psychiatric consultation. Beta testing with 50 patients over two months demonstrated feasibility and suggested that PRISM may improve provider screening rates and self-efficacy to address depression. On the basis of lessons learned, PRISM will be enhanced to integrate proactive patient engagement and monitoring into obstetric practices. PRISM may help overcome patient-, provider-, and system-level barriers to managing perinatal depression in obstetric settings.

Studies linked obesity with a large number of medical conditions including decreased cognitive functioning. The relation between BMI and cognition was proven in adults, but in adolescents the results are conflicting. Further, limited data are available on the impact of weight loss on cognition. This study analyzed the impact of a 30-week lasting weight loss program on cognition and determined the impact of changes in body composition and self-perceived fatigue on changes in cognition. Sixty-two obese adolescents were evaluated at baseline and after 30 weeks. Stroop test (ST; selective attention), Continuous Performance Test (CPT; sustained attention) and Ray Auditory verbal learning test (RAVLT; short-term memory) were assessed. Additionally, body composition parameters and fatigue (MFI-20) were evaluated. Improved reaction times were found for ST and CPT after the intervention, but were independent for reductions in BMI, fat mass, fat%, and fatigue. Short memory also improved with decreased fatigue as an influencing parameter. Accuracy of ST and CPT showed no significant changes. A 30-week lasting inpatient weight loss program improved selective attention, sustained attention, and short-term memory. Changes in body composition did not explain the improvements in cognitive functioning. Decreased fatigue resulted in improved aspects of cognition.

Testing included measurements of fat mass, bone-free lean mass (BFLM), body fat (%BF), lumbar-spine BMD, and 2000-m time-trial performance. After preseason testing, rowers participated in a periodized training program, with the addition of resistance training to the traditional aerobic-training program. Significant (P < .05) improvements in %BF, total mass, and BFLM were observed at midseason and postseason compared with preseason. Neither lumbar-spine BMD nor BMC significantly changed over the competitive season (P > .05). Finally, rowing performance (as measured by 2000-m time and average watts achieved) significantly improved at midseason and postseason compared with preseason. Our results highlight the efficacy of a seasonal concurrent training program serving to improve body composition and rowing performance, as measured by 2000-m times and average watts, among college-level rowers. Our findings offer practical applications for coaches and athletes looking to design a concurrent strength and aerobic training program to improve rowing performance across a season.

Kovach, L. S.; Zdankiewicz, E. M.

1987-01-01

Vapor compression distillation technology for phase change recovery of potable water from wastewater has evolved as a technically mature approach for use aboard the Space Station. A program to parametrically test an advanced preprototype Vapor Compression Distillation Subsystem (VCDS) was completed during 1985 and 1986. In parallel with parametric testing, a hardware improvement program was initiated to test the feasibility of incorporating several key improvements into the advanced preprototype VCDS following initial parametric tests. Specific areas of improvement included long-life, self-lubricated bearings, a lightweight, highly-efficient compressor, and a long-life magnetic drive. With the exception of the self-lubricated bearings, these improvements are incorporated. The advanced preprototype VCDS was designed to reclaim 95 percent of the available wastewater at a nominal water recovery rate of 1.36 kg/h achieved at a solids concentration of 2.3 percent and 308 K condenser temperature. While this performance was maintained for the initial testing, a 300 percent improvement in water production rate with a corresponding lower specific energy was achieved following incorporation of the improvements. Testing involved the characterization of key VCDS performance factors as a function of recycle loop solids concentration, distillation unit temperature and fluids pump speed. The objective of this effort was to expand the VCDS data base to enable defining optimum performance characteristics for flight hardware development.

To determine the impact of an educational program to improve the management of chronic obstructive pulmonary disease (COPD) that contributes to an increase of the quality of life, exercise capacity, level of dyspnoea, and clinical risk. Intervention study without controls. Primary Healthcare Centre. 193 patients with COPD were invited, 73 accepted and 55 participated in the educational program. Respiratory rehabilitation educational program with basic concepts of pulmonary and respiratory pathophysiology, respiratory physiotherapy exercises, practical workshop on the use of the most frequent inhalation devices, understanding of chronic disease and self-care measures in case of exacerbation. The quality of life (the COPD assessment test), exercise tolerance (the Six-Minute Walk Test), rating of perceived exertion (Borg Dyspnoea Score) and clinical risk (BODE index) were assessed by means of validated questionnaires in Spanish. A total of 43 (78.2%) participants completed the program. An improvement in the quality of life by a mean of 3.3 points was observed (95%CI; 1.76-4.84). Just over half (53.5%) of the participants obtained a clinically relevant improvement. Participants also improved their physical exercise capacity at post-intervention by increasing the distance that they walked in 6min by a mean of 20.76m (95%CI; 2.57-38.95). Improvements in the level of dyspnoea and clinical risk were also observed. The educational program shows a statistically significant and clinically relevant improvement in the quality of life, fatigue, symptomatology, exercise capacity, level of dyspnoea, and clinical risk. The program is adaptable to the health care routine of healthcare centres. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

The aim of this study was to assess the effect of a physical exercise program based on Mat Pilates (MP) with TheraBand ® on the dynamic balance of a sample population diagnosed with Parkinson's disease (PD). After random selection, 26 participants were allocated to a MP group or a control group where they performed calisthenics exercises. Both interventions lasted 12 weeks and involved 2 weekly sessions of 60 minutes. Assessments took place at baseline, 12 weeks after the intervention started and 4 weeks after the intervention was completed using the body mass index (BMI), the Timed Up and Go (TUG) test with Wiva ® sensors, the 30 Second Chair Stand test, and the Five Times Sit to Stand test. The group that completed the MP program presented significant improvements in BMI (F 1,21  = 3.986; p = 0.038), the 30 Second Chair Stand test (F 1,21  = 6.716; p = 0.014), the Five Times Sit to Stand test (F 1,21  = 5.213; p = 0.032), and the time required to complete the TUG dynamic balance test (F 1,21  = 5.035; p = 0.035). The MP program performed by a sample population with PD led to improvements in dynamic balance, and participants in the MP group showed increased strength in the lower limbs, but such improvements were not permanent after the activity ceased.

The purpose of this study was to examine the differences in anthropometric measurements using an aerobic and Pilates exercise program which lasted 24 weeks. This was a clinical intervention study of 303 women over the age of 60 living in Novi Sad, Serbia. Changes in body mass index and skinfold thickness were estimated through height, weight, and anthropometric measurements. The program comprised Pilates exercises for upper- and lower-body strength, agility, and aerobic capacity. Fat mass (FM) improved significantly (pre-test, 32.89%, 8.65; post-test, 28.25%, 6.58; P<0.01). Bone diameters and muscle perimeters showed no significant changes pre- and post-test (P>0.05), but there was a higher correlation between FM (%) and waist-hip ratio (rho, 0.80; P<0.01). A mixed program of aerobics and Pilates, controls and improves baseline muscle mass and decreases FM values, without causing deterioration during practice and follow-up exercises.

The provision of peer mentoring may improve tertiary education outcomes of students with autism spectrum disorder (ASD). This study evaluated the pilot year of the Curtin Specialist Mentoring Program (CSMP), a specialised peer mentoring program for university students with ASD aimed at improving self-reported well-being, academic success and retention in university studies. A single group pre-test, post-test design was employed. Quantitative and qualitative evaluations were undertaken with 10 young adults with ASD to explore the effectiveness and acceptability of the CSMP program. Students completed a battery of questionnaires focused on general anxiety, state communication apprehension, perceived communication competence, and communication apprehension both prior to, and five months after commencing enrolment in the CSMP. Information regarding academic success and retention was also obtained. Interviews with participants provided further insight into their experience of the program. Students enrolled in the CSMP showed significant improvement in social support and general communication apprehension assessment scores. Interviews revealed key features of the CSMP that may have contributed to these positive outcomes. The current study provides preliminary evidence that a specialised peer mentoring program can improve the well-being of students with ASD, and highlights the importance of interventions which are individualised, flexible, based on a social model, and target environmental factors such as social support.

Molecular tests potentially improving HPV screening and genotyping for cervical cancer prevention

PubMed Central

Gradíssimo, Ana

2018-01-01

INTRODUCTION Human papillomavirus (HPV)-related cancers can be averted by type-specific vaccination (primary prevention) and/or through detection and ablation of precancerous cervical lesions (secondary prevention). This review presents current challenges to cervical cancer screening programs, focusing on recent molecular advances in HPV testing and potential improvements on risk stratification. AREAS COVERED High-risk (HR)-HPV DNA detection has been progressively incorporated into cervix cancer prevention programs based on its increased sensitivity. Advances in next-generation sequencing (NGS) are being rapidly applied to HPV typing. However, current HPV DNA tests lack specificity for identification of cervical precancer (CIN3). HPV typing methods were reviewed based on published literature, with a focus on these applications for screening and risk stratification in the emerging complex clinical scenario post-vaccine introduction. In addition, the potential for NGS technologies to increase specificity is discussed in regards to reflex testing of specimens for emerging biomarkers for cervix precancer/cancer. EXPERT COMMENTARY Integrative multi-disciplinary molecular tests accurately triaging exfoliated cervical specimens will improve cervical cancer prevention programs while simplifying healthcare procedures in HPV-infected women. Hence, the concept of a “liquid-biopsy” (i.e., “molecular” Pap test) highly specific for early identification of cervical precancerous lesions is of critical importance in the years to come.

To evaluate whether balance training after total knee replacement surgery improves functional outcomes and to determine whether postoperative balance is associated with mobility. A prospective intervention study and randomized controlled trial with an intention-to-treat analysis. The rehabilitation center of a university-based teaching hospital. A total of 130 patients with knee osteoarthritis who had undergone total knee replacement surgery were recruited to attend an outpatient rehabilitation program. They were randomly allocated to additional balance rehabilitation and functional rehabilitation groups. During the eight-week outpatient rehabilitation program, both groups received general functional training. Patients in the balance rehabilitation group received an additional balance-based rehabilitation program. The functional reach test, single-leg stance test, 10-m walk test, Timed Up and Go Test, timed chair-stand test, stair-climb test, and Western Ontario and McMaster Universities Osteoarthritis Index were measured at baseline, eight weeks (T(1)), and 32 weeks (T(2)). The balance rehabilitation group patients demonstrated significant improvement in the results of the functional reach test at T(1) (37.6 ±7.8 cm) and T(2) (39.3 ±9.7 cm) compared with the baseline assessment (11.5 ±2.9 cm) and Timed Up and Go Test at T(1) (8.9 ±1.2 seconds) and T(2) (8.0 ±1.9 seconds) compared with the baseline assessment (12.5 ±1.8 seconds). Moreover, the balance rehabilitation group patients exhibited significantly greater improvements in balance and mobility than did the functional rehabilitation group patients (all P < 0.001). Furthermore, improved balance was significantly associated with improved mobility at T(2). Postoperative outpatient rehabilitation with balance training improves the balance, mobility, and functional outcomes in patients with knee osteoarthritis after total knee replacement. © The Author(s) 2014.

This study tests a theoretical cascade model in which multiple dimensions of facilitator delivery predict indicators of participant responsiveness, which in turn lead to improvements in targeted program outcomes. An effectiveness trial of the 10-session New Beginnings Program for divorcing families was implemented in partnership with four county-level family courts. This study included 366 families assigned to the intervention condition who attended at least one session. Independent observers provided ratings of program delivery (i.e., fidelity to the curriculum and process quality). Facilitators reported on parent attendance and parents' competence in home practice of program skills. At pretest and posttest, children reported on parenting and parents reported child mental health. We hypothesized effects of quality on attendance, fidelity and attendance on home practice, and home practice on improvements in parenting and child mental health. Structural Equation Modeling with mediation and moderation analyses were used to test these associations. Results indicated quality was significantly associated with attendance, and attendance moderated the effect of fidelity on home practice. Home practice was a significant mediator of the links between fidelity and improvements in parent-child relationship quality and child externalizing and internalizing problems. Findings provide support for fidelity to the curriculum, process quality, attendance, and home practice as valid predictors of program outcomes for mothers and fathers. Future directions for assessing implementation in community settings are discussed.

Effectiveness of a balance-focused exercise program for enhancing functional fitness of older adults at risk of falling: A randomised controlled trial.

PubMed

Zhao, Yanan; Chung, Pak-Kwong; Tong, Tom K

This study examined the effectivenss of a balance-focused training program (i.e., Exercise for Balance Improvement Program, ExBP) in improving functional fitness of older nonfallers at risk of falling. Sixty-one participants were randomly assigned to receive 16 weeks of ExBP or Tai Chi (TC) training, or no treatment (CON) with an 8-week follow-up. The Senior Fitness Test battery was applied to assess functional fitness. After the intervention, results revealed significant improvements in all fitness components in the ExBP group. Compared with the CON group, the ExBP group demonstrated more improvements in lower extremity muscle strength, agility and balance, and aerobic endurance. The ExBP group also displayed more improvements in aerobic endurance than the TC group in posttest and follow-up test. Therefore, the balance-focused exercise can be applied as an effective way in improving overall functional fitness among older nonfallers who are at risk of falling. Copyright © 2017 Elsevier Inc.

To evaluate the effects of a home-based upper limb training program on arm function in patients with multiple sclerosis (MS). Additionally, the effects of this program on manual dexterity, handgrip strength, and finger prehension force were analyzed. Randomized, single-blind controlled trial. Home based. Patients with a clinical diagnosis of MS acknowledging impaired manual ability (N=37) were randomized into 2 groups. Patients in the experimental group were included in a supervised home-based upper limb training program for 8 weeks twice a week. Patients in the control group received information in the form of a leaflet with a schedule of upper limb exercise training. The primary outcome measure was arm function (motor functioning assessed using the finger tapping test and a functional measure, the Action Research Arm Test). The secondary outcome measures were manual dexterity assessed with the Purdue Pegboard Test and handgrip strength and finger prehension force evaluated with a handgrip and a pinch dynamometer, respectively. After 8 weeks, a significant between-group improvement (P<.05) was found on the Action Research Arm Test bilaterally and the finger tapping test in the most affected upper limb. The secondary outcomes also improved in the most affected limb in the experimental group. An 8-week home-based intervention program focused on upper limbs twice a week improved arm function and physiologic variables with a primary focus on the more affected extremity in patients with MS compared with the control group.

To standardize patient handover in the chain of emergency care a handover guideline was developed. The main guideline recommendation is to use the DeMIST model (Demographics, Mechanism of Injury/illness, Injury/Illness, Signs, Treatment given) to structure pre-hospital notification and handover. To benefit from the new guideline, guideline adherence is necessary. As adherence to guidelines in emergency care settings is variable, there is a need to systematically implement the new guideline. For implementation of the guideline we developed a e-learning program tailored to influencing factors. The aim of the study was to evaluate the effectiveness of this e-learning program to improve emergency care professionals' adherence to the handover guideline during pre-hospital notification and handover in the chain of emergency medical service (EMS), emergency medical dispatch (EMD), and emergency department (ED). A prospective pre-test post-test study was conducted. The intervention was a tailored e-learning program that was offered to ambulance crew and emergency medical dispatchers (n=88). Data on adherence included pre-hospital notifications and handovers and were collected through observations and audiotapes before and after the e-learning program. Data were analyzed using X(2)-tests and t-tests. In total, 78/88 (88.6%) professionals followed the e-learning program. During pre- and post-test, 146 and 169 handovers were observed respectively. After the e-learning program, no significant difference in the number of handovers with the DeMIST model (77.9% vs. 73.1%, p=.319) and the number of handovers with the correct sequence of the DeMIST model (69.9% vs. 70.5%, p=.159) existed. During the handover, the number of questions by ED staff and interruptions significantly increased from 49.0% to 68.9% and from 15.2% to 52.7% respectively (both p=.000). Most handovers were performed after patient transfer, this did not change after the intervention (p=.167). The number of handovers where information was documented during handover slightly increased from 26.9% to 29.3% (p=.632). The tailored e-learning program did not improve adherence to a handover guideline in the chain of emergency care. Results show a relatively high baseline adherence rate to usage and correct sequence of the DeMIST model. Improvements in the handover process can be made on the documentation of information during handover, the number of interruptions and questions, and the handover moment.

2017-03-01

The cost of paratuberculosis to dairy herds, through decreased milk production, early culling, and poor reproductive performance, has been well-studied. The benefit of control programs, however, has been debated. A recent stochastic compartmental model for paratuberculosis transmission in US dairy herds was modified to predict herd net present value (NPV) over 25 years in herds of 100 and 1000 dairy cattle with endemic paratuberculosis at initial prevalence of 10% and 20%. Control programs were designed by combining 5 tests (none, fecal culture, ELISA, PCR, or calf testing), 3 test-related culling strategies (all test-positive, high-positive, or repeated positive), 2 test frequencies (annual and biannual), 3 hygiene levels (standard, moderate, or improved), and 2 cessation decisions (testing ceased after 5 negative whole-herd tests or testing continued). Stochastic dominance was determined for each herd scenario; no control program was fully dominant for maximizing herd NPV in any scenario. Use of the ELISA test was generally preferred in all scenarios, but no paratuberculosis control was highly preferred for the small herd with 10% initial prevalence and was frequently preferred in other herd scenarios. Based on their effect on paratuberculosis alone, hygiene improvements were not found to be as cost-effective as test-and-cull strategies in most circumstances. Global sensitivity analysis found that economic parameters, such as the price of milk, had more influence on NPV than control program-related parameters. We conclude that paratuberculosis control can be cost effective, and multiple control programs can be applied for equivalent economic results. Copyright © 2017 Elsevier B.V. All rights reserved.

Increasing proportion of the elderly in the driving population raises the importance of assuring their safety. We explored the effects of three different types of cognitive training on the cognitive function, brain structure, and driving safety of the elderly. Thirty-seven healthy elderly daily drivers were randomly assigned to one of three training groups: Group V trained in a vehicle with a newly developed onboard cognitive training program, Group P trained with a similar program but on a personal computer, and Group C trained to solve a crossword puzzle. Before and after the 8-week training period, they underwent neuropsychological tests, structural brain magnetic resonance imaging, and driving safety tests. For cognitive function, only Group V showed significant improvements in processing speed and working memory. For driving safety, Group V showed significant improvements both in the driving aptitude test and in the on-road evaluations. Group P showed no significant improvements in either test, and Group C showed significant improvements in the driving aptitude but not in the on-road evaluations. The results support the effectiveness of the onboard training program in enhancing the elderly's abilities to drive safely and the potential advantages of a multimodal training approach.

2017-08-01

This study was conducted to develop an Empowerment Education Program (EEP) for kidney transplant patients and to test the program's effects on uncertainty, self-care ability, and compliance. The research was conducted using a nonequivalent control group with a pretest-posttest design. The participants were 53 outpatients (experimental group: 25, control group: 28) who were receiving hospital treatment after kidney transplants. After the pre-test, patients in the experimental group underwent a weekly EEP for six weeks. The post-test was conducted immediately after, and four weeks after the program's completion in the same manner as the pre-test. For the control group, we conducted a post-test six and ten weeks after the pre-test, without and program intervention. A repeated measure ANOVA was performed to compare the change scores on main outcomes. Uncertainty was significantly lower in the experimental group than in the control group, both immediately after (t=-3.84, p=<.001) and 4 weeks after (t=-4.51 p=<.001) the program, whereas self-care ability (t=5.81, p=<.001), (t=5.84, p=<.001) and compliance (t=5.07, p=<.001), (t=5.45, p=<.001) were significantly higher. Kidney transplant patients who underwent an EEP showed a decrease in uncertainty and an improvement in self-care ability and compliance. Thus, our findings confirmed that an EEP can be an independent intervention method for improving and maintaining the health of kidney transplant patients. © 2017 Korean Society of Nursing Science

To examine the effects of a simulated emergency airway management education program on the self-efficacy and clinical performance among nurses in intensive care units. A one-group, pre- and post-test design was used. Thirty-five nurses who were working in adult intensive care units participated in this study. The simulation education program included lectures, skill demonstration, skill training, team-based practice, and debriefing. Self-efficacy and clinical performance questionnaires were completed before the program and 1 week after its completion. The data were analyzed by using descriptive statistics and the paired t-test to compare the mean differences between the pre-test and post-test. The scores before and after education were compared. After education, there was a significant improvement in the nurses' self-efficacy and clinical performance in emergency airway management situations. Simulation education effectively improved the self-efficacy and clinical performance of the nurses who were working in intensive care units. Based on the program for clinical nurses within a hospital, it will provide information that might advance clinical nursing education. © 2017 Japan Academy of Nursing Science.

Care of the trauma patient requires a well-coordinated intensive effort during the golden hour to optimize survival. We hypothesized that this program would improve knowledge, satisfaction, self-confidence, and simulated team performance. A pre-, post-test design with N = 7 BSN nurses, 21 years of age, less than 2 years of intensive care unit and nursing experience. Trauma intensive care unit, single-center academic Level 1 trauma center. Improvement was shown in perception of team structure (paired t test 13.71-12.57; p = .0001) and communication (paired t test 14.85-12.14; p = .009). Improvement was shown in observed situation monitoring (paired t test 17.42-25.28; p = .000), mutual support (paired t test 12.57-18.57; p = .000), and communication (paired t test 15.42-25.00; p = .001). A decrease was shown in attitudes of mutual support (paired t test 25.85-19.71; p = .04) and communication (paired t test 26.14-23.00; p = .001). Mean satisfaction scores were 21.5 of a possible 25 points. Mean self-confidence scores were 38.83 out of a possible 40 points. Simulation-based team training improved teamwork attitudes, perceptions, and performance. Team communication demonstrated significant improvement in 2 of the 3 instruments. Most participants agreed or strongly agreed that they were satisfied with simulation and had gained self-confidence.

The purpose of this study was to evaluate the effects of a home-based (HB) exercise program on anxiety levels and metabolic functions in patients with anxiety disorders in Taiwan. Purposive sampling was used to recruit 86 participants for this randomized, experimental study. Participants were asked to complete a pretest before the 3-month exercise program, a posttest at 1 week, and a follow-up test at 3 months after the exercise program. Study measures included four Self-Report Scales and biophysical assessments to collect and assess personal data, lifestyle behaviors, anxiety levels, and metabolic control functions. Of the 86 study participants, 83 completed the posttest and the 3-month follow-up test, including 41 in the experimental group and 42 in the control group. Participants in the experimental group showed significant improvements in body mass index, high-density lipoprotein cholesterol levels, and the level of moderate exercise after the program relative to the control group, as analyzed by generalized estimating equations mixed-model repeated measures. State and trait anxiety levels were also significantly improved from pretest to follow-up test in the experimental group. Finally, the prevalence of metabolic syndrome declined for participants in the experimental group. The HB exercise program produced positive effects on the metabolic indicators and anxiety levels of Taiwanese adults with anxiety disorders. Health providers should consider using similar HB exercise programs to help improve the mental and physical health of patients with anxiety disorders in their communities.

Adult education institutions have been identified as potential settings to improve health literacy and address the health inequalities that stem from limited health literacy. However, few health literacy interventions have been tested in this setting. Feasibility study for an RCT of the UK Skilled for Health Program adapted for implementation in Australian adult education settings. Implementation at two sites with mixed methods evaluation to examine feasibility, test for change in participants' health literacy and pilot test health literacy measures. Twenty-two socially disadvantaged adults with low literacy participated in the program and received 80-90 hours of health literacy instruction. The program received institutional support from Australia's largest provider of vocational education and training and was feasible to implement (100 % participation; >90 % completion; high teacher satisfaction). Quantitative results showed improvements in participants' health literacy skills and confidence, with no change on a generic measure of health literacy. Qualitative analysis identified positive student and teacher engagement with course content and self-reported improvements in health knowledge, attitudes, and communication with healthcare professionals. Positive feasibility results support a larger RCT of the health literacy program. However, there is a need to identify better, multi-dimensional measures of health literacy in order to be able to quantify change in a larger trial. This feasibility study represents the first step in providing the high quality evidence needed to understand the way in which health literacy can be improved and health inequalities reduced through Australian adult education programs.

A mobile HIV counseling and testing (HCT) program around Johannesburg piloted the integration of point-of-care (POC) CD4 testing, using the Pima analyzer, to improve linkages to HIV care. We report results from this pilot program for patients testing positive (n = 508) from May to October 2010. We analyzed 3 primary outcomes: assignment to testing group (offered POC CD4 or not), successful follow-up (by telephone), and completed the referral visit for HIV care within 8 weeks after HIV testing if successfully followed up. Proportions for each outcome were calculated, and relative risks were estimated using a modified Poisson approach. Three hundred eleven patients were offered the POC CD4 test, and 197 patients were not offered the test. No differences in patient characteristics were observed between the 2 groups. Approximately 62.7% of patients were successfully followed up 8 weeks after HIV testing, with no differences observed between testing groups. Among those followed up, 54.4% reported completing their referral visit. Patients offered the POC CD4 test were more likely to complete the referral visit for further HIV care (relative risk 1.25, 95% confidence interval: 1.00 to 1.57). In this mobile HCT setting, patients offered POC CD4 testing as part of the HCT services were more likely to visit a referral clinic after testing, suggesting that rapid CD4 testing technology may improve linkage to HIV care. Future research can evaluate options for adjusting HCT services if POC CD4 testing was included permanently and the cost-effectiveness of the POC CD4 testing compared with other approaches for improving linkage of care.

Mulkerrin, Elizabeth A.

The purpose of this study was to determine the effect of an 11th-grade and 12th-grade zoo-based academic high school experiential science program compared to a same school-district school-based academic high school experiential science program on students' pretest and posttest science, math, and reading achievement, and student perceptions of program relevance, rigor, and relationships. Science coursework delivery site served as the study's independent variable for the two naturally formed groups representing students (n = 18) who completed a zoo-based experiential academic high school science program and students (n = 18) who completed a school-based experiential academic high school science program. Students in the first group, a zoo-based experiential academic high school science program, completed real world, hands-on projects at the zoo while students in the second group, those students who completed a school-based experiential academic high school science program, completed real world, simulated projects in the classroom. These groups comprised the two research arms of the study. Both groups of students were selected from the same school district. The study's two dependent variables were achievement and school climate. Achievement was analyzed using norm-referenced 11th-grade pretest PLAN and 12th-grade posttest ACT test composite scores. Null hypotheses were rejected in the direction of improved test scores for both science program groups---students who completed the zoo-based experiential academic high school science program (p < .001) and students who completed the school-based experiential academic high school science program (p < .001). The posttest-posttest ACT test composite score comparison was not statistically different ( p = .93) indicating program equipoise for students enrolled in both science programs. No overall weighted grade point average score improvement was observed for students in either science group, however, null hypotheses were rejected in the direction of improved science grade point average scores for 11th-grade (p < .01) and 12th-grade (p = .01) students who completed the zoo-based experiential academic high school science program. Null hypotheses were not rejected for between group posttest science grade point average scores and school district criterion reference math and reading test scores. Finally, students who completed the zoo-based experiential academic high school science program had statistically improved pretest-posttest perceptions of program relationship scores (p < .05) and compared to students who completed the school-based experiential academic high school science program had statistically greater posttest perceptions of program relevance (p < .001), perceptions of program rigor (p < .001), and perceptions of program relationships (p < .001).

A comparison of fitness-case sampling methods for genetic programming

Martínez, Yuliana; Naredo, Enrique; Trujillo, Leonardo; Legrand, Pierrick; López, Uriel

2017-11-01

Genetic programming (GP) is an evolutionary computation paradigm for automatic program induction. GP has produced impressive results but it still needs to overcome some practical limitations, particularly its high computational cost, overfitting and excessive code growth. Recently, many researchers have proposed fitness-case sampling methods to overcome some of these problems, with mixed results in several limited tests. This paper presents an extensive comparative study of four fitness-case sampling methods, namely: Interleaved Sampling, Random Interleaved Sampling, Lexicase Selection and Keep-Worst Interleaved Sampling. The algorithms are compared on 11 symbolic regression problems and 11 supervised classification problems, using 10 synthetic benchmarks and 12 real-world data-sets. They are evaluated based on test performance, overfitting and average program size, comparing them with a standard GP search. Comparisons are carried out using non-parametric multigroup tests and post hoc pairwise statistical tests. The experimental results suggest that fitness-case sampling methods are particularly useful for difficult real-world symbolic regression problems, improving performance, reducing overfitting and limiting code growth. On the other hand, it seems that fitness-case sampling cannot improve upon GP performance when considering supervised binary classification.

To assess the short-term and 1-year outcomes of children with fibromyalgia treated with intensive physical and occupational therapy (PT/OT) and psychotherapy. Children with fibromyalgia seen at a tertiary care hospital were treated with 5-6 hours of intensive PT/OT daily and at least 4 hours of psychosocial services weekly. All medications used for fibromyalgia were discontinued. Children underwent standardized testing, including a visual analog scale for pain; the Bruininks-Oseretsky Test of Motor Performance, Second Edition; the Bruce treadmill protocol; the Functional Disability Inventory; the Pain Stages of Change Questionnaire, adolescent version; and the Pediatric Quality of Life Inventory, Teen Report, at 3 time points: at program entry, at the end of the intensive program, and 1 year after the end of the program. Sixty-four children (median age, 16 years; 95% Caucasian; 94% female; median duration of symptoms, 21 months) were studied. The mean pain score decreased significantly from program entry to the end of the program (from 66 of 100 to 25 of 100; P = .001). At the 1-year follow-up, 33% reported no pain. All measures of function on the Bruininks-Oseretsky Test of Motor Performance, Second Edition improved significantly and remained at that level or continued to improve over the subsequent year. The mean Bruce treadmill protocol time first increased from 588 seconds to 801 seconds (P < .001) and then dropped to 750 seconds (P = .005), which is at the 90th percentile for age and sex. All Pain Stages of Change Questionnaire, adolescent version subset scores improved significantly initially and were stable or improved at 1 year, as did the Pediatric Quality of Life Inventory, Teen Report total score. Children with fibromyalgia can be successfully treated without medications with a very intensive PT/OT and psychotherapy program. They have significantly improved pain and function by subject report and objective measures of function. Copyright © 2015 The Authors. Published by Elsevier Inc. All rights reserved.

Type 2 spinocerebelar ataxia (SCA2) is a neurodegenerative disease with higher prevalence and incidence in Holguín province, Cuba. At present, there is not any drug to counteract the loss of coordinative motor capacities of these patients. Thus physical training seems to be the only way to attenuate the course of disease. To evaluate the effectiveness of a physical training program on quantitative neurological indices in SCA2 patients. A samples of 87 SCA2 patients were studied. All subjects underwent a six month physical exercise program based on coordination, balance and muscular conditioning exercises. Quantitative tests were applied to all patients both before and after the application of the exercise program. Comparisons between pretest versus posttest values were made to evaluate the improvement in neurological indices. All neurological indices both with open eyes and closed eyes significantly improved from pretest to posttest. Static balance, evaluated by Romberg test, also enhanced with training. The exercise training program significantly improved the neurological indices in SCA2 patient with mild stage of disease.

To estimate the effectiveness of a short-term educational-counseling worksite program focused on lipid intake, by monitoring the possible change on nutrition knowledge and eating habits. an 8-week educational program based on the Health Belief Model was implemented in a honey packaging and sales company in Greece. 20 out of the 29 employees initially enrolled completed the program. Knowledge level and eating habits were evaluated prior and after the intervention by the "Nutrition Knowledge Questionnaire" and the "Food Habits Questionnaire". ANOVA, Spearman rho test and paired Wilcoxon test were employed in statistical analysis. Non smokers and those with higher educational level had healthier eating habits. Knowledge following the intervention was significantly improved concerning recommendations and basic food ingredients but as far as eating habits were concerned, scores were not improved significantly, while intake of fried food was increased. Short-term interventions may produce substantial improvement in knowledge but not necessarily modifications in unhealthy eating habits.

Hearing impairment may affect the body posture maintenance. The aim of the study was to evaluate the effect of modified Pilates exercise program on the body posture maintenance in hearing impaired people. Eighty students (aged 13-24) were enrolled and randomly allocated into two groups: test group (n = 41) which attended an original program based on modified Pilates exercises and control group (n = 39) which attended standard physical education classes. Stabilographic tests were conducted at baseline and after 6-week training program. Both groups showed improved control of body balance in a standing position manifested in reductions of the length of path, surface area, and speed of deflection. Modified Pilates program was significantly more effective in improving body balance control in relaxed posture and with feet together than standard physical education classes. The greater efficiency of the modified Pilates program was expressed in a significant improvement in balance control parameters, i.e., path length, surface area, and speed of deflection. The modified Pilates program was more effective in improving body balance control in the hearing impaired people than standard physical education classes. Modification of physical activity recommendations for hearing impaired students may be considered; however, further research is required. Implications for Rehabilitation Hearing impairment impacts the mental, social and, physical spheres of life as well as deteriorates equivalent reactions and the way body posture is maintained. In hearing impaired people, control of body balance and muscle coordination is often disturbed, thus more attention should be paid to exercises associated with balance which may improve the ability to learn and develop motor skills. Modified Pilates program was significantly more effective in improving body balance control than standard physical education classes in hearing impaired people.

Simulation-based programs are increasingly being used to teach obstetrics and gynaecology examinations, but it is difficult to establish student learning acquired through them. Assessment may test student learning but its role in learning itself is rarely recognised. We undertook this study to assess medical and midwifery student learning through a simulation program using a pre-test and post-test design and also to evaluate use of assessment as a method of learning. The interprofessional simulation education program consisted of a brief pre-reading document, a lecture, a video demonstration and a hands-on workshop. Over a 24-month period, 405 medical and 104 midwifery students participated in the study and were assessed before and after the program. Numerical data were analysed using paired t-test and one-way analysis of variance. Students' perceptions of the role of assessment in learning were qualitatively analysed. The post-test scores were significantly higher than the pre-test (P < 0.001) with improvements in scores in both medical and midwifery groups. Students described the benefit of assessment on learning in preparation of the assessment, reinforcement of learning occurring during assessment and reflection on performance cementing previous learning as a post-assessment effect. Both medical and midwifery students demonstrated a significant improvement in their test scores and for most students the examination process itself was a positive learning experience. © 2017 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Many production systems employ standardized statistical monitors that measure defect rates and cycle times, as indices of performance quality. Clinical laboratory testing, a system that produces test results, is amenable to such monitoring. To demonstrate patterns in clinical laboratory testing defect rates and cycle time using 7 College of American Pathologists Q-Tracks program monitors. Subscribers measured monthly rates of outpatient order-entry errors, identification band defects, and specimen rejections; median troponin order-to-report cycle times and rates of STAT test receipt-to-report turnaround time outliers; and critical values reporting event defects, and corrected reports. From these submissions Q-Tracks program staff produced quarterly and annual reports. These charted each subscriber's performance relative to other participating laboratories and aggregate and subgroup performance over time, dividing participants into best and median performers and performers with the most room to improve. Each monitor's patterns of change present percentile distributions of subscribers' performance in relation to monitoring durations and numbers of participating subscribers. Changes over time in defect frequencies and the cycle duration quantify effects on performance of monitor participation. All monitors showed significant decreases in defect rates as the 7 monitors ran variously for 6, 6, 7, 11, 12, 13, and 13 years. The most striking decreases occurred among performers who initially had the most room to improve and among subscribers who participated the longest. All 7 monitors registered significant improvement. Participation effects improved between 0.85% and 5.1% per quarter of participation. Using statistical quality measures, collecting data monthly, and receiving reports quarterly and yearly, subscribers to a comparative monitoring program documented significant decreases in defect rates and shortening of a cycle time for 6 to 13 years in all 7 ongoing clinical laboratory quality monitors.

The purpose of the study was to examine the long term effects of a selective muscle strengthening program in reducing pain and improving knee function and strength in athletes with Patellofemoral Pain Syndrome. A total of one hundred and thirty four athletes were enrolled in the study. All patients were evaluated with Isokinetic Test, Cincinnati Knee Rating System and Visual Analogue Scale. The selective muscle strengthening consisted of 8 weeks of exercises performed 3 times in the first 4 weeks and twice in the last 4 weeks. The muscle strengthening program was performed between 30-90° of knee flexion. During the first 4-weeks treatment we used closed kinetic chain exercises with 3 sets of 8 repetitions at 80% of maximum load. In the last 4-weeks we added open kinetic chain exercises at 70% of maximum load with 3 sets and 10 repetitions to improve the resistance. Analyzing data at the beginning and at the end of the treatment for Isokinetic test, Cincinnati and Visual Analogue Scale we observed a significant scores improvement. At 1 year follow-up the clinical improvements were maintained and everyone followed the recommended program because did not perform the maintenance program. At 2 years follow-up no athletes presented relapses; only four patients were excluded from program. We believe that our program of selective muscle strengthening should resolve pain and improve knee function and strength as results in obtained scores and could be critical to avoid painful relapses.

We describe how we used the framework of the U.S. Department of Veterans Affairs (VA) Quality Enhancement Research Initiative (QUERI) to develop a program to improve rates of diagnostic testing for the Human Immunodeficiency Virus (HIV). This venture was prompted by the observation by the CDC that 25% of HIV-infected patients do not know their diagnosis - a point of substantial importance to the VA, which is the largest provider of HIV care in the United States. Following the QUERI steps (or process), we evaluated: 1) whether undiagnosed HIV infection is a high-risk, high-volume clinical issue within the VA, 2) whether there are evidence-based recommendations for HIV testing, 3) whether there are gaps in the performance of VA HIV testing, and 4) the barriers and facilitators to improving current practice in the VA.Based on our findings, we developed and initiated a QUERI step 4/phase 1 pilot project using the precepts of the Chronic Care Model. Our improvement strategy relies upon electronic clinical reminders to provide decision support; audit/feedback as a clinical information system, and appropriate changes in delivery system design. These activities are complemented by academic detailing and social marketing interventions to achieve provider activation. Our preliminary formative evaluation indicates the need to ensure leadership and team buy-in, address facility-specific barriers, refine the reminder, and address factors that contribute to inter-clinic variances in HIV testing rates. Preliminary unadjusted data from the first seven months of our program show 3-5 fold increases in the proportion of at-risk patients who are offered HIV testing at the VA sites (stations) where the pilot project has been undertaken; no change was seen at control stations. This project demonstrates the early success of the application of the QUERI process to the development of a program to improve HIV testing rates. Preliminary unadjusted results show that the coordinated use of audit/feedback, provider activation, and organizational change can increase HIV testing rates for at-risk patients. We are refining our program prior to extending our work to a small-scale, multi-site evaluation (QUERI step 4/phase 2). We also plan to evaluate the durability/sustainability of the intervention effect, the costs of HIV testing, and the number of newly identified HIV-infected patients. Ultimately, we will evaluate this program in other geographically dispersed stations (QUERI step 4/phases 3 and 4).

Prospective cohort study without a control group. Firstly, to present our 5-week progressive exercise therapy program in the early stage after anterior cruciate ligament (ACL) injury. Secondly, to evaluate changes in knee function after completion of the program for patients with ACL injury in general and also when classified as potential copers or noncopers, and, finally, to examine potential adverse events. Few studies concerning early-stage ACL rehabilitation protocols exist. Consequently, little is known about the tolerance for, and outcomes from, short-term exercise therapy programs in the early stage after injury. One-hundred patients were included in a 5-week progressive exercise therapy program, within 3 months after injury. Knee function before and after completion of the program was evaluated from isokinetic quadriceps and hamstrings muscle strength tests, 4 single-leg hop tests, 2 different self-assessment questionnaires, and a global rating of knee function. A 2-way mixed-model analysis of variance was conducted to evaluate changes from pretest to posttest for the limb symmetry index for muscle strength and single-leg hop tests, and the change in scores for the patient-reported questionnaires. In addition, absolute values and the standardized response mean for muscle strength and single-leg hop tests were calculated at pretest and posttest for the injured and uninjured limb. Adverse events during the 5-week period were recorded. The progressive 5-week exercise therapy program led to significant improvements (P<.05) in knee function from pretest to posttest both for patients classified as potential copers and noncopers. Standardized response mean values for changes in muscle strength and single-leg hop performance from pretest to posttest for the injured limb were moderate to strong (0.49-0.84), indicating the observed improvements to be clinically relevant. Adverse events occurred in 3.9% of the patients. Short-term progressive exercise therapy programs are well tolerated and should be incorporated in early-stage ACL rehabilitation, either to improve knee function before ACL reconstruction or as a first step in further nonoperative management.

There is a need for feasible, evidence-based interventions that support HIV risk reduction among heterosexual Black men. In this article, we describe the process for development of the Barbershop Talk With Brothers (BTWB) program and evaluation. The BTWB program is a theoretically grounded and community-based HIV prevention program that seeks to improve individual skills and motivation to decrease sexual risk, and that builds men's interest in and capacity for improving their community's health. Formative data collection included barbershop observations and barber focus groups, brief behavioral risk assessments of men in barbershops, and focus groups and individual interviews. Based on this information and in consultation with our steering committee, we developed the BTWB program and accompanying program evaluation. From April through November 2011, 80 men were recruited and completed a baseline assessment of a pilot test of the program; 78 men completed the program and 71 completed a 3-month assessment. The pilot evaluation procedures were feasible to implement, and assessments of pre- and post-test measures indicate that key behavioral outcomes and proposed mediators of those outcomes changed in hypothesized directions. Specifically, attitudes and self-efficacy toward consistent condom use improved, and respondents reported lower levels of sexual risk behavior from baseline to follow-up (all p < 0.05). Perceptions of community empowerment also increased (p = 0.06). While HIV stigma decreased, this difference did not reach statistical significance. Our approach to community-engaged program development resulted in an acceptable, feasible approach to reaching and educating heterosexual Black men about HIV prevention in community settings.

Objective: To determine if the flexibility of high-school-aged males would improve after a 6-week eccentric exercise program. In addition, the changes in hamstring flexibility that occurred after the eccentric program were compared with a 6-week program of static stretching and with a control group (no stretching). Design and Setting: We used a test-retest control group design in a laboratory setting. Subjects were assigned randomly to 1 of 3 groups: eccentric training, static stretching, or control. Subjects: A total of 69 subjects, with a mean age of 16.45 ± 0.96 years and with limited hamstring flexibility (defined as 20° loss of knee extension measured with the thigh held at 90° of hip flexion) were recruited for this study. Measurements: Hamstring flexibility was measured using the passive 90/90 test before and after the 6-week program. Results: Differences were significant for test and for the test-by-group interaction. Follow-up analysis indicated significant differences between the control group (gain = 1.67°) and both the eccentric-training (gain = 12.79°) and static-stretching (gain = 12.05°) groups. No difference was found between the eccentric and static-stretching groups. Conclusions: The gains achieved in range of motion of knee extension (indicating improvement in hamstring flexibility) with eccentric training were equal to those made by statically stretching the hamstring muscles.

Implementing an injury prevention program to athletes under age 12 years may reduce injury rates. There is limited knowledge regarding whether these young athletes will be able to modify balance and performance measures after completing a traditional program that has been effective with older athletes or whether they require a specialized program for their age. The purpose of this study was to compare the effects of a pediatric program, which was designed specifically for young athletes, and a traditional program with no program in the ability to change balance and performance measures in youth athletes. We used a cluster-randomized controlled trial to evaluate the effects of the programs before and after a 9-week intervention period. Sixty-five youth soccer athletes (males: n = 37 mass = 34.16 +/- 5.36 kg, height = 143.07 +/- 6.27 cm, age = 10 +/- 1 yr; females: n = 28 mass = 33.82 +/- 5.37 kg, height = 141.02 +/- 6.59 cm) volunteered to participate and attended 2 testing sessions in a research laboratory. Teams were cluster-randomized to either a pediatric or traditional injury prevention program or a control group. Change scores for anterior-posterior and medial-lateral time-to-stabilization measures and maximum vertical jump height and power were calculated from pretest and post-test sessions. Contrary with our original hypotheses, the traditional program resulted in positive changes, whereas the pediatric program did not result in any improvements. Anterior-posterior time-to-stabilization decreased after the traditional program (mean change +/- SD = -0.92 +/- 0.49 s) compared with the control group (-0.49 +/- 0.59 s) (p = 0.003). The traditional program also increased vertical jump height (1.70 +/- 2.80 cm) compared with the control group (0.20 +/- 0.20 cm) (p = 0.04). There were no significant differences between control and pediatric programs. Youth athletes can improve balance ability and vertical jump height after completing an injury prevention program. Training specificity appears to affect improvements and should be considered with future program design.

Objective To evaluate the efficacy of a mammography boot camp (MBC) to improve radiologists' performance in interpreting mammograms in the National Cancer Screening Program (NCSP) in Korea. Materials and Methods Between January and July of 2013, 141 radiologists were invited to a 3-day educational program composed of lectures and group practice readings using 250 digital mammography cases. The radiologists' performance in interpreting mammograms were evaluated using a pre- and post-camp test set of 25 cases validated prior to the camp by experienced breast radiologists. Factors affecting the radiologists' performance, including age, type of attending institution, and type of test set cases, were analyzed. Results The average scores of the pre- and post-camp tests were 56.0 ± 12.2 and 78.3 ± 9.2, respectively (p < 0.001). The post-camp test scores were higher than the pre-camp test scores for all age groups and all types of attending institutions (p < 0.001). The rate of incorrect answers in the post-camp test decreased compared to the pre-camp test for all suspicious cases, but not for negative cases (p > 0.05). Conclusion The MBC improves radiologists' performance in interpreting mammograms irrespective of age and type of attending institution. Improved interpretation is observed for suspicious cases, but not for negative cases. PMID:25246818

Although sleep hygiene education represents a promising approach for patients with poor sleep quality, little research has been devoted in understanding the sleep hygiene behavior and knowledge of working women. The purpose of this study was to investigate the efficacy of a short-term sleep hygiene education program on working women with poor sleep quality. This pilot study was a prospective and an exploratory intervention study. The intervention was tested on 37 selected working women with poor sleep quality in the community. The Pittsburgh Sleep Quality Index (score > 5) was used to identify working women with poor sleep quality. After a pretest to assess sleep quality, researchers implemented a 5-week sleep hygiene education program that addressed good sleep environments/habits, emotional stress, the influence of diet/alcohol/tobacco on sleep, exercise, and alternative therapies. Tests administered midway through the program and after program completion provided the data used to analyze effective sleep quality changes. Results showed sleep hygiene education to improve participant sleep quality significantly (p < .001). The sleep quality of all participants improved over both the 3- and the 5-week education program. The six components of the Pittsburgh Sleep Quality Index (i.e., subjective sleep quality, sleep latency, sleep duration, sleep disturbances, use of sleeping medication, and daytime dysfunction) also improved. A brief and effective sleep hygiene education program delivered by a nurse can improve sleep quality in working women with sleeping problems.

Introduction The provision of peer mentoring may improve tertiary education outcomes of students with autism spectrum disorder (ASD). This study evaluated the pilot year of the Curtin Specialist Mentoring Program (CSMP), a specialised peer mentoring program for university students with ASD aimed at improving self-reported well-being, academic success and retention in university studies. Methods A single group pre-test, post-test design was employed. Quantitative and qualitative evaluations were undertaken with 10 young adults with ASD to explore the effectiveness and acceptability of the CSMP program. Students completed a battery of questionnaires focused on general anxiety, state communication apprehension, perceived communication competence, and communication apprehension both prior to, and five months after commencing enrolment in the CSMP. Information regarding academic success and retention was also obtained. Interviews with participants provided further insight into their experience of the program. Results Students enrolled in the CSMP showed significant improvement in social support and general communication apprehension assessment scores. Interviews revealed key features of the CSMP that may have contributed to these positive outcomes. Conclusions The current study provides preliminary evidence that a specialised peer mentoring program can improve the well-being of students with ASD, and highlights the importance of interventions which are individualised, flexible, based on a social model, and target environmental factors such as social support.

The scale-up of effective HIV viral load (VL) testing is an urgent public health priority. Implementation of testing is supported by the availability of accurate, nucleic acid based laboratory and point-of-care (POC) VL technologies and strong WHO guidance recommending routine testing to identify treatment failure. However, test implementation faces challenges related to the developing health systems in many low-resource countries. The purpose of this commentary is to review the challenges and solutions from the large-scale implementation of other diagnostic tests, namely nucleic-acid based early infant HIV diagnosis (EID) and CD4 testing, and identify key lessons to inform the scale-up of VL. Experience with EID and CD4 testing provides many key lessons to inform VL implementation and may enable more effective and rapid scale-up. The primary lessons from earlier implementation efforts are to strengthen linkage to clinical care after testing, and to improve the efficiency of testing. Opportunities to improve linkage include data systems to support the follow-up of patients through the cascade of care and test delivery, rapid sample referral networks, and POC tests. Opportunities to increase testing efficiency include improvements to procurement and supply chain practices, well connected tiered laboratory networks with rational deployment of test capacity across different levels of health services, routine resource mapping and mobilization to ensure adequate resources for testing programs, and improved operational and quality management of testing services. If applied to VL testing programs, these approaches could help improve the impact of VL on ART failure management and patient outcomes, reduce overall costs and help ensure the sustainable access to reduced pricing for test commodities, as well as improve supportive health systems such as efficient, and more rigorous quality assurance. These lessons draw from traditional laboratory practices as well as fields such as logistics, operations management and business. The lessons and innovations from large-scale EID and CD4 programs described here can be adapted to inform more effective scale-up approaches for VL. They demonstrate that an integrated approach to health system strengthening focusing on key levers for test access such as data systems, supply efficiencies and network management. They also highlight the challenges with implementation and the need for more innovative approaches and effective partnerships to achieve equitable and cost-effective test access. © 2017 The Authors.

The aim of this study was to investigate the influence of a ballroom dancing program on the postural balance of institutionalized elderly residents. The sample consisted of 59 sedentary elderly residents of long-stay institutions who were randomly assigned to a ballroom dancing experimental group (EG, n=30) or a control group (CG, n=29). The ballroom dancing program consisted of three 50-min sessions each week on alternate days over a 12-week period. The dances included the foxtrot, waltz, rumba, swing, samba and bolero. The medical records of the subjects were reviewed to determine the number of falls they experienced in the three months prior to the intervention. Postural static balance was assessed using a Lizard (Med. EU., Italy, 2010) stabilometric and posturometric platform. Only patients in the EG lost a significant amount of weight (Δ=-2.85 kg) when comparing the pre- and post-test postural balance assessments. The intergroup comparison revealed a reduced lower limb weight distribution difference in the EG post-test compared to the CG post-test (p=0.012). In the intragroup comparison, the EG patients experienced significantly fewer falls post-test relative to pre-test (p<0.0001). This improvement was not observed for patients in the CG. In the intergroup analysis, we observed fewer falls in the EG post-test compared to the CG post-test (p<0.0001). Therefore it was conclude that sedentary elderly people living in long-term institutions can improve their balance via a ballroom dancing program. This activity improved balance and reduced the number of falls in this elderly population. Copyright © 2014. Published by Elsevier Ireland Ltd.

The present study was conducted to assess knowledge and attitude of unmarried female students in King Abdul-Aziz University (KAU) towards premarital screening (PMS) program, to determine predictors of high students' knowledge scores and to improve their knowledge about PMS through conduction of an educational campaign. Multi-stage stratified random sample method was used with recruitment of 1563 students from all faculties of KAU, during the educational year 2008-2009. The Pre-test included 30 knowledge items and 14 attitude statements with student's response through a 5-point Likert scale. Health education was conducted using audiovisual aids through pre-designed educational materials. Statistical analysis was done by SPSS version 16. Students' knowledge about the program was generally low before the educational campaign. The predictors of high knowledge scores were being a health science student (aOR=4.15; 95% CI: 2.97-5.81), age ≥20 years (aOR=2.78; 95% CI: 2.01-3.85), family history of hereditary diseases and income ≥10,000 SR/month. Regarding attitude, almost all students (99.0%) agreed on the importance of PMS. After the educational program, students' knowledge about PMS was markedly improved. The mean students' knowledge score was 9.85 ± 5.36 in Pre-test and improved to 18.45 ± 4.96 in Post-test, with a highly statistical significant difference (paired t=25.40, p<0.000). The educational program was successful in improving students' knowledge about the PMS. Conduction of similar educational programs and adding PMS in the curriculum of secondary and university education are recommended.

2016-01-01

One of the most significant current discussions has led to the hypothesis that domain-specific training programs alone are not enough to improve reading achievement or working memory abilities. Incremental or Entity personal conceptions of intelligence may be assumed to be an important prognostic factor to overcome domain-specific deficits. Specifically, incremental students tend to be more oriented toward change and autonomy and are able to adopt more efficacious strategies. This study aims at examining the effect of personal conceptions of intelligence to strengthen the efficacy of a multidimensional intervention program in order to improve decoding abilities and working memory. Participants included two children (M age = 10 years) with developmental dyslexia and different conceptions of intelligence. The children were tested on a whole battery of reading and spelling tests commonly used in the assessment of reading disabilities in Italy. Afterwards, they were given a multimedia test to measure motivational factors such as conceptions of intelligence and achievement goals. The children took part in the T.I.R.D. Multimedia Training for the Rehabilitation of Dyslexia (Rappo and Pepi, 2010) reinforced by specific units to improve verbal working memory for 3 months. This training consisted of specific tasks to rehabilitate both visual and phonological strategies (sound blending, word segmentation, alliteration test and rhyme test, letter recognition, digraph recognition, trigraph recognition, and word recognition as samples of visual tasks) and verbal working memory (rapid words and non-words recognition). Posttest evaluations showed that the child holding the incremental theory of intelligence improved more than the child holding a static representation. On the whole this study highlights the importance of treatment programs in which both specificity of deficits and motivational factors are both taken into account. There is a need to plan multifaceted intervention programs based on a transverse approach, considering both cognitive and motivational factors. PMID:26779069

Under funding from the Advanced Research Projects Agency (ARPA) and the US Marine Corps (USMC), Lawrence Livermore National Laboratory (LLNL) has directed a program aimed at improving detection capabilities against buried mines and munitions. The program has provided a national test facility for buried mines in arid environments, compiled and distributed an extensive data base of infrared (IR), ground penetrating radar (GPR), and other measurements made at that site, served as a host for other organizations wishing to make measurements, made considerable progress in the use of ground penetrating radar for mine detection, and worked on the difficult problem ofmore » sensor fusion as applied to buried mine detection. While the majority of our effort has been concentrated on the buried mine problem, LLNL has worked with the U.S.M.C. on surface mine problems as well, providing data and analysis to support the COBRA (Coastal Battlefield Reconnaissance and Analysis) program. The original aim of the experimental aspect of the program was the utilization of multiband infrared approaches for the detection of buried mines. Later the work was extended to a multisensor investigation, including sensors other than infrared imagers. After an early series of measurements, it was determined that further progress would require a larger test facility in a natural environment, so the Buried Object Test Facility (BOTF) was constructed at the Nevada Test Site. After extensive testing, with sensors spanning the electromagnetic spectrum from the near ultraviolet to radio frequencies, possible paths for improvement were: improved spatial resolution providing better ground texture discrimination; analysis which involves more complicated spatial queueing and filtering; additional IR bands using imaging spectroscopy; the use of additional sensors other than IR and the use of data fusion techniques with multi-sensor data; and utilizing time dependent observables like temperature.« less

Balance and motor impairments are most evident among inactive individuals with ID that might be particularly susceptible to a loss of basic functioning and further limit the person's autonomy in activities of daily living. The aim of the study was to assess the effect of a 12-week trampoline exercise intervention program on motor and balance ability of school aged children with intellectual disability (ID). Eighteen healthy schools aged children (mean age=10.3 ± 1.6 years) with moderate ID were assigned either to an experimental group (n=9) or a control group (n=9). The experiment group attended a 12 weeks trampoline training intervention program consisting of daily individualized 20-min sessions, while the control group followed the regular school schedule. Balance was assessed using three tasks of increased difficulty (double-leg stance with eyes opened or closed, and one-leg stance with eyes opened) performed while standing on an electronic pressure platform (EPS). Motor performance of all participants was tested using sit and reach test and long and vertical jump tests all derived from the Eurofit Test Battery of physical fitness. Trampoline intervention resulted in significant improvements of participants' performance in all motor and balance tests. In conclusion, trampoline training can be an effective intervention for improving functional outcomes and can be recommended as an alternative mode of physical activity programming for improving balance and motor performance. Furthermore, it also supports the idea that individuals with ID require enjoyable and interesting intervention programs such as the trampoline program used in this study so as to remain active and consequently to facilitate their overall development and promote a more active and healthier way of life.

Performance seeking control program overview

Orme, John S.

1995-01-01

The Performance Seeking Control (PSC) program evolved from a series of integrated propulsion-flight control research programs flown at NASA Dryden Flight Research Center (DFRC) on an F-15. The first of these was the Digital Electronic Engine Control (DEEC) program and provided digital engine controls suitable for integration. The DEEC and digital electronic flight control system of the NASA F-15 were ideally suited for integrated controls research. The Advanced Engine Control System (ADECS) program proved that integrated engine and aircraft control could improve overall system performance. The objective of the PSC program was to advance the technology for a fully integrated propulsion flight control system. Whereas ADECS provided single variable control for an average engine, PSC controlled multiple propulsion system variables while adapting to the measured engine performance. PSC was developed as a model-based, adaptive control algorithm and included four optimization modes: minimum fuel flow at constant thrust, minimum turbine temperature at constant thrust, maximum thrust, and minimum thrust. Subsonic and supersonic flight testing were conducted at NASA Dryden covering the four PSC optimization modes and over the full throttle range. Flight testing of the PSC algorithm, conducted in a series of five flight test phases, has been concluded at NASA Dryden covering all four of the PSC optimization modes. Over a three year period and five flight test phases 72 research flights were conducted. The primary objective of flight testing was to exercise each PSC optimization mode and quantify the resulting performance improvements.

Since the Pap test was introduced in the 1940s, there has been an approximately 70% reduction in the incidence of squamous cell cervical cancers in many developed countries by the application of organized and opportunistic screening programs. The efficacy of the Pap test, however, is hampered by high interobserver variability and high false-negative and false-positive rates. The use of biomarkers has demonstrated the ability to overcome these issues, leading to improved positive predictive value of cervical screening results. In addition, the introduction of HPV primary screening programs will necessitate the use of a follow-up test with high specificity to triage the high number of HPV-positive tests. This paper will focus on protein biomarkers currently available for use in cervical cancer screening, which appear to improve the detection of women at greatest risk for developing cervical cancer, including Ki-67, p16INK4a, BD ProEx C, and Cytoactiv HPV L1.

1983-01-01

A major limitation of downhole mud motors for geothermal drilling, as well as straight-hole oil and gas drilling, is the bearing section. Reduced bearing life results from the inability to seal a lubricant in the bearing pack. A reliable rotary seal will extend the bearing life and will allow high pressure drops across the bit for improved bottomhole cleaning and increased drilling rate. This paper summarizes the results of a six-year program funded by the U.S. Department of Energy/Division of Geothermal Energy to develop a sealed bearing pack for use with downhole motors in geothermal applications. Descriptions of the Sealmore » Test Machine, Lubricant Test Machine and Bearing Pack Test Facility are presented. Summaries of all seal tests, lubricant tests and bearing pack tests are provided; and a comprehensive program bibliography is presented.« less

2003-12-01

Because individuals at risk for HIV and STDs are concentrated in prisons and jails, incarceration is an opportunity to provide HIV and STD testing. We interviewed 72 service providers working in U.S. prisons in four states about their experiences with and perceptions regarding HIV and STD testing in prison. Providers' job duties represented administration, education, security, counseling, and medical care. Providers' knowledge of prison procedures and programs related to HIV and STD testing was narrowly limited to their specific job duties, resulting in many missed opportunities for prevention counseling and referral. Suggestions include increasing health care and counseling staff so posttest counseling can be provided for those with negative as well as positive test results, providing additional prevention programs for incarcerated persons, improving staff training about HIV and STD testing, and improving communication among in-prison providers as well as between corrections and public health staff.

Few studies have considered the effectiveness of outpatient rehabilitation programs for stroke patients. The objective of this study was to assess the effectiveness of a hospital-based interdisciplinary outpatient stroke rehabilitation program with respect to physical functioning, mobility, and balance. The Comprehensive Outpatient Rehabilitation Program provides a hospital-based interdisciplinary approach to stroke rehabilitation in Southwestern Ontario. Outcome measures from physiotherapy and occupational therapy sessions were available at intake and discharge from the program. A series of paired sample t-tests were performed to assess patient changes between time points for each outcome measure. A total of 271 patients met the inclusion criteria for analysis (56.1% male; mean age = 62.9 ± 13.9 years). Significant improvements were found between admission and discharge for the Functional Independence Measure, grip strength, Chedoke-McMaster Stroke Assessment, two-minute walk test, maximum walk test, Timed Up and Go, Berg Balance Scale, and one-legged stance (P < .003 for all). The findings indicate that an interdisciplinary rehabilitation program was effective at improving the physical functioning, mobility, and balance of individuals after a stroke. A hospital-based, stroke-specific rehabilitation program should be considered when patients continue to experience deficits after inpatient rehabilitation.

Online continuing medical education (CME) offers a number of advantages for physicians including flexibility with regards to location and timing of use. In order to effect physician practices and improve patient outcomes, it is important that the development of online CME is theory and evidence-based. This paper aims to describe the development of an online CME program for practising general practitioners (GPs) on vitamin D and sun health called "The ABC's of Vitamin D for GPs" using elements of design principles for physician-education web sites as a framework. The paper will also report the program's usability and acceptability pilot test results. The ABC's of Vitamin D program was developed following nine principles: needs assessment; evidence-based content development; multimodal program and modularisation; clinical cases; tailoring and interactivity; audit and feedback; credibility of the web site host; patient education materials; ease of use and navigation. Among the 20 GPs invited, acceptability and useability was tested with 12 GPs (60%) who agreed to participate and were interviewed following use of the program. The study was conducted between 2011 and 2013. An online CME program consisting of eight modules was constructed. Of the 12 participating GPs, most (n=11) reported that the program was clear and easy to understand, logical, easy to navigate, and took a reasonable amount of time (estimated between 1 and 3h) to complete. Eleven of 12 participants said they would use the program as an accredited CME activity and all participants indicated that the program was 'very or somewhat' likely to lead to changes in the advice patients are given. This study found that a theory and evidence based approach for the development of an online CME program for GPs was acceptable to users. Further research is needed to examine whether the online CME program is effective at changing GP practices and improving patient outcomes. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Background Physical activity has been shown to be beneficial for improving cognitive function in healthy older adults. However there is limited research on the benefits of physical activity on cognitive performance after stroke. Objective To determine if a combined exercise and recreation program can improve the executive functioning and memory in individuals with chronic stroke. Methods 11 ambulatory subjects with chronic stroke (mean age 67±10.8 years) participated in a 6 month program of exercise for 2 hours and recreation for 1 hour weekly. Executive functions and memory were assessed at baseline, 3, and 6 months by a battery of standard neuropsychological tests including response inhibition, cognitive flexibility, dual task (motor plus cognitive) and memory. Motor ability was also assessed. Non-parametric statistics were used to assess the differences between the three assessments. Results At baseline, substantial deficits in all aspects of executive functioning were revealed. From baseline to 3 mo, the mean improvement was 10±14% (χ2=9.3, p=0.0025) for the dual task (Walking while Talking), −3±22% (χ2=2.4, p>0.05) for response inhibition (Stroop test) and 61±69% (χ2=8.0, p=0.04) for memory (Rey Auditory Verbal Learning Test - long delay). From baseline to 6 months, the mean improvement was 7±7.5% (χ2=12.0, p=0.007) for response inhibition (Stroop Test). In addition, knee strength and walking speed improved significantly at 3 months. Conclusions This pilot study suggests that exercise and recreation may improve memory and executive functions of community dwelling individuals with stroke. Further studies require a larger sample size and a control group. PMID:20460494

Plyometric training programs have been implemented in anterior cruciate ligament injury prevention programs. Plyometric exercises are designed to aid in the improvement of muscle strength and neuromuscular control. Our purpose was to examine the effects of plyometric training on lower leg strength in women. Thirty (age = 20.3 ± 1.9 years) recreationally active women were divided into control and experimental groups. The experimental group performed a plyometric training program for 6 weeks, 3 d·wk(-1). All subjects attended 4 testing sessions: before the start of the training program and after weeks 2, 4, and 6. Concentric quadriceps and hamstring strength (dominant leg) was assessed using an isokinetic dynamometer at speeds of 60 and 120°·s(-1). Peak torque, average peak torque, and average power (AvgPower) were measured. The results revealed a significant (p < 0.05) interaction between time and group for flexion PkTq and AvgPower at 120°·s(-1). Post hoc analysis further revealed that PkTq at 120°·s(-1) was greater in the plyometric group than in the control group at testing session 4 and that AvgPower was greater in the plyometric group than in the control group in testing sessions 2-4. Our results indicate that the plyometric training program increased hamstring strength while maintaining quadriceps strength, thereby improving the Q:H strength ratio.

Contributions of After School Programs to the Development of Fundamental Movement Skills in Children.

PubMed

Burrows, E Jean; Keats, Melanie R; Kolen, Angela M

Fundamental movement skill (FMS) proficiency or the ability to perform basic skills (e.g., throwing, catching and jumping) has been linked to participation in lifelong physical activity. FMS proficiency amongst children has declined in the previous 15 years, with more children performing FMS at a low-mastery level. These declines may help explain the insufficient levels of participation in health promoting physical activity seen in today's youth. The after school time period (e.g., 3 to 6 p.m.), is increasingly considered an opportune time for physical activity interventions. To date, little research has examined the potential for after school programming to improve FMS proficiency. Participants (n=40, 6-10 years) of two existent physical activity based after school programs, a low-organized games and a sports-based program, were pre- and post-tested for FMS proficiency using the Test of Gross Motor Development-2 (TGMD-2) over an 11-week period. The sports-based program participants showed no improvement in FMS over the 11-week study ( p =0.91, eta 2 =0.00) and the games-based program participants significantly improved their proficiency ( p =0.00, eta 2 =0.30). No significant ( p =0.13, eta 2 = 0.06), differences were found in change in FMS scores between the low-organized games program participants and the sport-based program participants. These results suggest that after school programs with a low-organized games-based focus may support a moderate improvement in FMS proficiency in young children. Better training of after school program leaders on how to teach FMS may be necessary to assist children in acquiring sufficient proficiency in FMS.

Purpose Two stuttering measurement training programs currently used for training clinicians were evaluated for their efficacy in improving the accuracy of total stuttering event counting. Method Four groups, each with 12 randomly allocated participants, completed a pretest–posttest design training study. They were evaluated by their counts of stuttering events on eight 3-min audiovisual speech samples from adults and children who stutter. Stuttering judgment training involved use of either the Stuttering Measurement System (SMS), Stuttering Measurement Assessment and Training (SMAAT) programs, or no training. To test for the reliability of any training effect, SMS training was repeated with the 4th group. Results Both SMS-trained groups produced approximately 34% improvement, significantly better than no training or the SMAAT program. The SMAAT program produced a mixed result. Conclusions The SMS program was shown to produce a “medium” effect size improvement in the accuracy of stuttering event counts, and this improvement was almost perfectly replicated in a 2nd group. Half of the SMAAT judges produced a 36% improvement in accuracy, but the other half showed no improvement. Additional studies are needed to demonstrate the durability of the reported improvements, but these positive effects justify the importance of stuttering measurement training. PMID:25629956

Despite documented efficacy and recommendations, pulmonary rehabilitation (PR) in chronic obstructive pulmonary disease (COPD) has been underutilized. Home-based PR was proposed as an alternative, but there were limited data. The adequate exercise intensity was also a crucial issue. The aim of this study was to investigate the effects of home-based PR with a metronome-guided walking pace on functional exercise capacity and health-related quality of life (HRQOL) in COPD. The subjects participated in a 12-week home-based PR program. Exercise intensity was initially determined by cardiopulmonary exercise test, and was readjusted (the interval of metronome beeps was reset) according to submaximal endurance test. Six-minute walk test, pulmonary function test, cardiopulmonary exercise test, and St. George's Respiratory Questionnaire (SGRQ) were done before and after the 12-week program, and at 6 months after completion of rehabilitation. Thirty-three patients participated in the program. Six-minute walking distance was significantly increased (48.8 m; P = 0.017) and the SGRQ score was also improved (-15; P < 0.001) over the six-month follow-up period after rehabilitation. There were no significant differences in pulmonary function and peak exercise parameters. We developed an effective home-based PR program with a metronome-guided walking pace for COPD patients. This rehabilitation program may improve functional exercise capacity and HRQOL.

We investigated the effectiveness of three different rehabilitative programs: group exercise, individual core stability or balance training intervention with a stabilometric platform to improve balance ability in elderly hospitalized patients. We used a prospective quasi-experimental study design. Twenty-eight patients, 39.3% women [age (mean±SD) 72.4±6.5 years], known to have had at least a fall in the last 12 months, were consecutively assigned to one of the following three groups: group exercise intervention, individual core stability or balance training with a stabilometric platform (five sessions a week for 3 weeks in each group). Outcomes were collected at baseline and immediately following the intervention period. In each intervention group, patients showed improvement in balance and mobility, shown as an improvement in the three functional tests score (the Tinetti scale, the Berg Balance Scale, and the Time Up and Go test) (all, P<0.05), whereas, generally, the changes in the score of the test of the stabilometric platform (Postural Stability Test and Fall Risk Test) were not significant for all the interventions. No significant group-by-time interaction was detected for any of the intervention groups, which suggests that the groups improved in the same way. These findings indicate that participation in an exercise program can improve balance and functional mobility, which might contribute toward the reductions of the falls of elderly hospitalized patients and the subsequent fall-related costs. Functional scales might be more appropriate than an instrumental test (Postural Stability Test and Fall Risk Test of the Biodex Balance System) in detecting the functional improvement because of a rehabilitative intervention.

To assess if a 12-week exercise intervention to improve aerobic fitness, muscle strength, and core stability also had an impact on fatigue, pain, activity, and participation in adults with Pompe disease, an inherited neuromuscular disorder. Open-label trial. Change was assessed by the chi-square test and Wilcoxon signed-rank test. Physiotherapy practices. Mildly affected adult patients with Pompe disease who were not dependent on ventilators and/or walking devices and were receiving enzyme replacement therapy. Patients participated in a 12-week exercise program, which included 36 sessions of standardized aerobic, resistance, and core stability exercises. Before and after the training program we evaluated fatigue (Fatigue Severity Scale), pain (yes/no), motor function (Quantitative Muscle Function Test, Rasch-built Pompe-specific Activity Scale), amount of physical activity (activity monitor), and health status (Medical Outcomes Study 36-Item Short-Form Health Survey). Of the 25 patients enrolled, 23 completed the program. At the end of the program, levels of fatigue (median, 5.33 to 4.78, P=.01) and pain (56.5% to 21.7%, P=.04) improved. The quality of motor function and the amount of physical activity patients engaged in did not change. Changes in pain and fatigue were not related to improvements in aerobic fitness or muscle strength. This study in mildly affected adult patients with Pompe disease suggests that a combined training program aiming to increase aerobic fitness, muscle strength, and core stability also leads to improvements in fatigue and pain.

These inspection programs consist of the following: Supplemental Inspection Documents; Corrosion Prevention and Control Documents; Repair Assessment Documents; and Service Bulletin Compliance Documents. In addition, airframe manufacturers perform extended airframe fatigue tests to deal with potential problems before they can develop in the fleet. Lastly, nondestructive inspection (NDI) plays a role in all these programs through the detection of cracks, corrosion, and disbonds. However, improved and more cost effective NDI methods are needed. Some methods such as magneto-optic imaging, electronic shearography, Diffractor-Sight, and multi-parameter eddy current testing appear viable for near-term improvements in NDI of aging aircraft.

The Accreditation Council for Graduate Medical Education Milestone Project for general surgery provided a more robust method for developing and tracking residents' competence. This framework enhanced systematic and progressive development of residents' competencies in surgical quality improvement. A 22-month interactive, educational program based on resident-specific surgical outcomes data culminated in a quality improvement project for postgraduate year 4 surgery residents. Self- assessment, quality knowledge test, and resident-specific American College of Surgeons National Surgical Quality Improvement Program Quality In-Training Initiative morbidity were compared before and after the intervention. Quality in-training initiative morbidity decreased from 25% (82/325) to 18% (93/517), p = 0.015 despite residents performing more complex cases. All participants achieved level 4 competency (4/4) within the general surgery milestones improvement of care, practice-based learning and improvement competency. Institutional American College of Surgeons National Surgical Quality Improvement Program general surgery morbidity improved from the ninth to the sixth decile. Quality assessment and improvement self-assessment postintervention scores (M = 23.80, SD = 4.97) were not significantly higher than preintervention scores (M = 19.20, SD = 5.26), p = 0.061. Quality Improvement Knowledge Application Tool postintervention test scores (M = 17.4, SD = 4.88), were not significantly higher than pretest scores (M = 13.2, SD = 1.92), p = 0.12. Sharing validated resident-specific clinical data with participants was associated with improved surgical outcomes. Participating fourth year surgical residents achieved the highest score, a level 4, in the practice based learning and improvement competency of the improvement of care practice domain and observed significantly reduced surgical morbidity for cases in which they participated.

This article is part of the Focus Theme of Methods of Information in Medicine on "New Methodologies for Patients Rehabilitation". For Guillain-Barré patients, motor rehabilitation programs are helpful at the onset to prevent the complications of paralysis and in cases of persistent motor impairment. Traditional motor rehabilitation programs may be tedious and monotonous, resulting in low adherence to the treatments. A Virtual Motor Rehabilitation system has been tested in Guillain-Barré patients to increase patient adherence and to improve clinical results. Two people with Guillain-Barré performed 20 rehabilitation sessions. We tested a novel system based on Motor Virtual Rehabilitation in three periods of time (baseline evaluation, final evaluation, and follow-up. In the training program, the participants carried out a specific treatment using the Active Balance Rehabilitation system (ABAR). The system is composed of customizable virtual games to perform static and dynamic balance rehabilitation. Significant improvements in clinical results were obtained by both participants, with significant results in the static balance clinical test of the Anterior Reach test in the standing position and unipedal stance time. Other significant results were found in dynamic balance clinical tests in the Berg Balance Scale test and the 30-second Sit-to-Stand test. With regard to acceptance of the system, both patients enjoyed the experience, and both patients thought that this system was helpful for their rehabilitation. The results show that Virtual Motor Rehabilitation for Guillain-Barré patients provides clinical improvements in an entertaining way.

Accreditation in Ontario, Canada, requires that licensed clinical laboratories participate in external quality assessment (also known as proficiency testing) and perform competency evaluation of their staff. To assess the extent of ongoing competency assessment practices, the Quality Management Program--Laboratory Services (QMP-LS) Microbiology Committee surveyed all 112 licensed Ontario microbiology laboratories. The questionnaire consisted of a total of 21 questions that included yes/no, multiple-choice, and short-answer formats. Participants were asked to provide information about existing programs, the frequency of testing, what areas are evaluated, and how results are communicated to the staff. Of the 111 responding laboratories, 6 indicated they did not have a formal evaluation program since they perform only limited bacteriology testing. Of the remaining 105 respondents, 87% perform evaluations at least annually or every 2 years, and 61% include any test or task performed, whereas 16% and 10% focus only on problem areas and high-volume complex tasks, respectively. The most common methods of evaluation were review of external quality assessment (EQA) challenges, direct observation, and worksheet review. With the exception of one participant, all communicate results to staff, and most take remedial action to correct the deficiencies. Although most accredited laboratories have a program to assess the ongoing competency of their staff, the methods used are not standardized or consistently applied, indicating that there is room for improvement. The survey successfully highlighted potential areas for improvement and allowed the QMP-LS Microbiology Committee to provide guidance to Ontario laboratories for establishing or improving existing microbiology-specific competency assessment programs.

Preventing falls in assisted living: Results of a quality improvement pilot study.

PubMed

Zimmerman, Sheryl; Greene, Angela; Sloane, Philip D; Mitchell, Madeline; Giuliani, Carol; Nyrop, Kirsten; Walsh, Edith

Residents of assisted living (AL) communities are at high risk for falls, which result in negative outcomes and high health care costs. Adapting effective falls prevention programs for AL quality improvement (QI) has the potential to reduce falls, improve resident quality of life, and reduce costs. This project tested the feasibility and outcomes of an evidence-based multi-component QI program, the Assisted Living Falls Prevention and Monitoring Program (AL-FPMP). Resident posture and gait improved, likely due to exercise and/or physical therapy. Effective falls prevention QI programs can be implemented in AL, and are advised to (1) establish and maintain a falls team to create a culture focused on the reduction of falls risk; (2) teach staff to assess residents using the Morse Falls Scale to increase their awareness of residents' falls risk and improvement; and (3) modify existing exercise programs to address balance and lower body strength.

2012-12-01

The purpose of this study was to investigate effects of Oral Function Improvement Exercises on salivation, xerostomia and halitosis in elderly people. The participants in the study were 48 female community-dwelling elders in D city. The Oral Function Improvement Exercises were given 3 times a week, for a total of 24 times from August to October 2011. Spitting method, Visual Analogue Scale, and halimeter (mBA-21) were used to evaluate the effects of Oral Function Improvement Exercises on salivation, xerostomia, and halitosis. The data were analyzed using χ²-test and t-test with the SPSS program. The experimental group had significantly better salivation, and less xerostomia and halitosis than the control group. The results indicate that Oral Function Improvement Exercises were effective for salivation, xerostomia and halitosis in the elders. Therefore, it was suggested that Oral Function Improvement Exercise are applicable in a community nursing intervention program to improve the quality of life for elders.

The purpose of this study was to examine the longitudinal effects of a strength and conditioning program on selected body composition and performance data over 4 consecutive years of training. Body mass, percent body fat, lean body mass, proagility (18.3 m shuttle), 36.6-m (40-yd) sprint, bench press, chin-ups, vertical jump, and power index data for 84 National Collegiate Athletic Association division IA collegiate football players were examined. In addition to examining data on all athletes, data were analyzed on specific groups categorized by position. Groups were categorized as (a) skill (wide receivers, defensive backs, and running backs), (b) big skill (linebackers, kickers, tight ends, quarterbacks, and specialists), and (c) line (offensive and defensive linemen). Data on each individual performance criteria were analyzed using pairwise t-tests to indicate changes from year to year. Results for all participants showed that the greatest number of significant improvements among test parameters occurred during the first year of training. Years 2-4 of training demonstrated inconsistent improvement among the test parameters. Bench press performance significantly improved throughout 4 years of training among all participants. Data analysis from specific position groups also revealed the greatest number of significant improvements occurred during the first year of training. Overall, the results of this study clearly demonstrate that the greatest rate of improvement in the selected performance parameters occurred during the initial year of the strength and conditioning program. This study provides valuable information for coaches to establish appropriate progression and program variation guidelines for athletes over consecutive years of training.

A program of analysis, design, fabrication and testing has been conducted to develop computer programs for predicting rocket engine turbopump inducer hydrodynamic loading, stress magnitude and distribution, and vibration characteristics. Methods of predicting blade loading, stress, and vibration characteristics were selected from a literature search and used as a basis for the computer programs. An inducer, representative of typical rocket engine inducers, was designed, fabricated, and tested with special instrumentation selected to provide measurements of blade surface pressures and stresses. Data from the tests were compared with predicted values and the computer programs were revised as required to improve correlation. For Volume 1 see N71-20403. For Volume 2 see N71-20404.

Bodden, Jamie G; Needham, Robert A; Chockalingam, Nachiappan

2015-01-01

This study assessed the basic fundamental movements of mixed martial arts (MMA) athletes using the functional movement screen (FMS) assessment and determined if an intervention program was successful at improving results. Participants were placed into 1 of the 2 groups: intervention and control groups. The intervention group was required to complete a corrective exercise program 4 times per week, and all participants were asked to continue their usual MMA training routine. A mid-intervention FMS test was included to examine if successful results were noticed sooner than the 8-week period. Results highlighted differences in FMS test scores between the control group and intervention group (p = 0.006). Post hoc testing revealed a significant increase in the FMS score of the intervention group between weeks 0 and 8 (p = 0.00) and weeks 0 and 4 (p = 0.00) and no significant increase between weeks 4 and 8 (p = 1.00). A χ analysis revealed that the intervention group participants were more likely to have an FMS score >14 than participants in the control group at week 4 (χ = 7.29, p < 0.01) and week 8 (χ = 5.2, p ≤ 0.05). Finally, a greater number of participants in the intervention group were free from asymmetry at week 4 and week 8 compared with the initial test period. The results of the study suggested that a 4-week intervention program was sufficient at improving FMS scores. Most if not all, the movements covered on the FMS relate to many aspects of MMA training. The knowledge that the FMS can identify movement dysfunctions and, furthermore, the fact that the issues can be improved through a standardized intervention program could be advantageous to MMA coaches, thus, providing the opportunity to adapt and implement new additions to training programs.

Given the rarity of in-hospital pediatric emergency events, identification of gaps and inefficiencies in the code response can be difficult. In-situ, simulation-based medical education programs can identify unrecognized systems-based challenges. We hypothesized that developing an in-situ, simulation-based pediatric emergency response program would identify latent inefficiencies in a complex, dual-hospital pediatric code response system and allow rapid intervention testing to improve performance before implementation at an institutional level. Pediatric leadership from two hospitals with a shared pediatric code response team employed the Institute for Healthcare Improvement's (IHI) Breakthrough Model for Collaborative Improvement to design a program consisting of Plan-Do-Study-Act cycles occurring in a simulated environment. The objectives of the program were to 1) identify inefficiencies in our pediatric code response; 2) correlate to current workflow; 3) employ an iterative process to test quality improvement interventions in a safe environment; and 4) measure performance before actual implementation at the institutional level. Twelve dual-hospital, in-situ, simulated, pediatric emergencies occurred over one year. The initial simulated event allowed identification of inefficiencies including delayed provider response, delayed initiation of cardiopulmonary resuscitation (CPR), and delayed vascular access. These gaps were linked to process issues including unreliable code pager activation, slow elevator response, and lack of responder familiarity with layout and contents of code cart. From first to last simulation with multiple simulated process improvements, code response time for secondary providers coming from the second hospital decreased from 29 to 7 min, time to CPR initiation decreased from 90 to 15 s, and vascular access obtainment decreased from 15 to 3 min. Some of these simulated process improvements were adopted into the institutional response while others continue to be trended over time for evidence that observed changes represent a true new state of control. Utilizing the IHI's Breakthrough Model, we developed a simulation-based program to 1) successfully identify gaps and inefficiencies in a complex, dual-hospital, pediatric code response system and 2) provide an environment in which to safely test quality improvement interventions before institutional dissemination.

2016-03-01

The aim of this study was to investigate the immediate effects of trunk stabilization exercise (SE) and conventional trunk exercise (CE) programs on jump performance. 13 adolescent male soccer players performed 2 kinds of jump testing before and immediate after 3 experimental conditions: SE, CE, and non-exercise (NE). The SE program consisted of the elbow-toe, hand-knee, and back bridge, and the CE program consisted of the sit-up, sit-up with trunk rotation and back extension. Testing of a countermovement jump (CMJ) and rebound jump (RJ) were performed to assess jump performance. Jump height of the CMJ and RJ-index, contact time, and jump height of the RJ were analyzed. The RJ index was improved significantly only after SE (p=0.017). However, contact time and jump height did not improve significantly in the SE condition. Moreover, no significant interaction or main effects of time or group were observed in the CMJ. Consequently, this study showed the different immediate effect on the RJ between the SE and CE, and suggested the possibility that the SE used in this study is useful as a warm-up program to improve the explosive movements. © Georg Thieme Verlag KG Stuttgart · New York.

The accumulated knowledge about the negative impact of financial strain on couple's relationship functioning and the magnitude of the latest economic downturn have brought together the fields of financial counseling and couples' therapy. This article describes the development of a new interdisciplinary program that aims at helping couples under financial strain improve their financial management, communication, and dyadic coping skills. The article also reports the results from its initial pilot-testing with data collected from 18 financially distressed couples before and after participation in the program and 3 months later. Results from repeated measures ANOVAs suggest that the program may help reduce both partners' financial strain and the male negative communication and improve both partners' financial management skills and strategies to cope together with financial strain, and the male relationship satisfaction. These findings together with the high satisfaction reported by participants regarding the structure and content of the sessions and homework suggest that this program may be a promising approach to help couples experiencing financial strain. Gender differences, clinical implications, and possibilities for further research are also discussed. © 2014 American Association for Marriage and Family Therapy.

Virtual environments have been used to assess children with ADHD but have never been tested as therapeutic tools. We tested a new virtual classroom cognitive remediation program to improve symptoms in children with ADHD. In this randomized clinical trial, 51 children with ADHD (7-11 years) were assigned to a virtual cognitive remediation group, a methylphenidate group, or a psychotherapy group. All children were evaluated before and after therapy with an ADHD Rating Scale, a Continuous Performance Test (CPT), and a virtual classroom task. After therapy by virtual remediation, children exhibited significantly higher numbers of correct hits on the virtual classroom and CPT. These improvements were equivalent to those observed with methylphenidate treatment. Our study demonstrates for the first time that a cognitive remediation program delivered in a virtual classroom reduces distractibility in children with ADHD and could replace methylphenidate treatment in specific cases.

To assess the efficacy of an exercise program aiming to improve balance and muscular strength, for postural control and muscular strength of women with osteoporosis. Sample consisted of 33 women with osteoporosis, randomized into one of two groups: intervention group, in which exercises for balance and improvement of muscular strength of the inferior members were performed for 8 wks (n = 17, age 72.8 +/- 3.6 yrs); control group, which was women not practicing exercises (n = 16, age 74.4 +/- 3.7 yrs). At baseline and after 8 wks of treatment, postural control was assessed using a force plate (Balance Master, Neurocom), and muscular strength during ankle dorsiflexion, knee extension, and flexion was assessed by dynamometry. Adherence to the program was 82%. When compared with the control group, individuals in the intervention group significantly improved the center of pressure velocity (P = 0.02) in the modified clinical test of sensory interaction for balance test, center of pressure velocity (P < 0.01), and directional control (P < 0.01) in limits of stability test, isometric force during ankle dorsiflexion (P = 0.01), knee extension (P < 0.01), and knee flexion (P < 0.01). Balance and strength exercises are effective in improving postural control and lower-limb strength in elderly women with osteoporosis.

Using data from Botswana's largest HIV testing and counseling (HTC) provider, Tebelopele, we evaluate populations served and gender-specific correlates of testing HIV-positive among clients of two programs: standalone centers and outreach testing. Client records from January to June 2007 (n = 47,890) were evaluated by HTC program and gender. Bivariate and multivariate analyses were performed to identify demographic, testing, and risk-behavior variables associated with testing HIV-positive. Compared to outreach testing, standalone centers served proportionally more clients who were young, well-educated, unmarried, and HIV-infected; outreach testing reached an older, less-educated population. Age, educational attainment, marital status, couples testing, testing because of illness or discordant relationship, and nonuse of condoms (among young clients only) were consistently associated with testing HIV-positive, by HTC program and gender. Our evaluation suggests that Tebelopele standalone and outreach HTC programs serve different populations, and identifies strategies to reduce HIV infection risk and to improve uptake of HTC by HIV-infected, undiagnosed Batswana.

NASA s Aviation Safety Program was created for the purpose of making a significant reduction in the incidents of weather related aviation accidents by improving situational awareness. The objectives of that program are being met in part through advances in weather sensor technology, and in part through advances in the communications technology that are developed for use in the National Airspace System. It is this latter element, i.e., the improvements in aviation communication technologies, that is the focus of the Weather Information Communications project. This report describes the final flight test results completed under the WINCOMM project at the NASA Glenn Research Center of the 1090 Extended Squitter (1090ES) and VDL Mode 3 (VDL-3) data links as a medium for weather data exchange. It presents the use of 1090ES to meet the program objectives of sending broadcast turbulence information and the use of VDL-3 to send graphical weather images. This report provides the test requirements and test plans, which led to flight tests, as well as final results from flight testing. The reports define the changes made to both avionics and ground-based receivers as well as the ground infrastructure to support implementation of the recommended architecture, with a focus on the issues associated with these changes.

Improved self-management skills predict improvements in quality of life and depression in patients with chronic disorders.

2016-08-01

Self-management programs aim to improve patients' skills to manage their chronic condition in everyday life. Improvement in self-management is assumed to bring about improvements in more distal outcomes, such as quality of life. This study aimed to test the hypothesis that changes in self-reported self-management skills observed after participation in self-management programs predict changes in both quality of life and depressive symptoms three months later. Using latent change modeling, the relationship between changes in latent variables over three time points (start and end of rehabilitation, after three months) was analysed. The sample comprised 580 patients with different chronic conditions treated in inpatient rehabilitation clinics. The influence of additional predictor variables (age, sex, perceived social support) and type of disorder as a moderator variable was also tested. Changes in self-reported self-management skills after rehabilitation predicted changes in both quality of life and depressive symptoms at the end of rehabilitation and the 3 months follow-up. These relationships remained significant after the inclusion of other predictor variables and were similar across disorders. The findings provide support for the hypothesis that improvements in proximal outcomes of self-management programs may foster improvements in distal outcomes. Further studies should investigate treatment mechanisms. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Designing an HIV counseling and testing program for bathhouses: the Seattle experience with strategies to improve acceptability.

Spielberg, Freya; Branson, Bernard M; Goldbaum, Gary M; Kurth, Ann; Wood, Robert W

2003-01-01

Bathhouses are important venues for providing HIV counseling and testing to high-risk men who have sex with men (MSM), yet relatively few bathhouses routinely provide this service, and few data are available to guide program design. We examine numerous logistic considerations that had been identified in the HIV Alternative Testing Strategies study and that influenced the initiation, effectiveness, and maintenance of HIV testing programs in bathhouses for MSM. Key programmatic considerations in the design of a bathhouse HIV counseling and testing program included building alliances with community agencies, hiring and training staff, developing techniques for offering testing, and providing options for counseling, testing, and disclosure of results. The design included ways to provide client support and follow-up for partner notification and treatment counseling and to maintain relationships with bathhouse management for support of prevention activities. Early detection of HIV infection and HIV prevention can be achieved for some high-risk MSM through an accessible and acceptable HIV counseling and testing program in bathhouses. Keys to success include establishing community prevention collaborations between bathhouse personnel and testing agencies, ensuring that testing staff are supported in their work, and offering anonymous rapid HIV testing. Use of FDA approved, new rapid tests that do not require venipuncture, centrifugation, or laboratory oversight will further decrease barriers to testing and facilitate implementation of bathhouse testing programs in other communities.

Patients after Fontan operation for complex congenital heart disease (CHD) have decreased exercise capacity and report reduced health-related quality of life (HRQOL). Studies suggest hospital-based cardiac physical activity programs can improve HRQOL and exercise capacity in patients with CHD; however, these programs have variable adherence rates. The impact of a home-based cardiac physical activity program in Fontan survivors is unclear. This pilot study evaluated the safety, feasibility, and benefits of an innovative home-based physical activity program on HRQOL in Fontan patients. A total of 14 children, 8-12 years, with Fontan circulation enrolled in a 12-week moderate/high intensity home-based cardiac physical activity program, which included a home exercise routine and 3 formalized in-person exercise sessions at 0, 6, and 12 weeks. Subjects and parents completed validated questionnaires to assess HRQOL. The Shuttle Test Run was used to measure exercise capacity. A Fitbit Flex Activity Monitor was used to assess adherence to the home activity program. Of the 14 patients, 57% were male and 36% had a dominant left ventricle. Overall, 93% completed the program. There were no adverse events. Parents reported significant improvement in their child's overall HRQOL (P < .01), physical function (P < .01), school function (P = .01), and psychosocial function (P < .01). Patients reported no improvement in HRQOL. Exercise capacity, measured by total shuttles and exercise time in the Shuttle Test Run and calculated VO2 max, improved progressively from baseline to the 6 and 12 week follow up sessions. Monthly Fitbit data suggested adherence to the program. This 12-week home-based cardiac physical activity program is safe and feasible in preteen Fontan patients. Parent proxy-reported HRQOL and objective measures of exercise capacity significantly improved. A 6-month follow up session is scheduled to assess sustainability. A larger study is needed to determine the applicability and reproducibility of these findings in other age groups and forms of complex CHD. © 2016 Wiley Periodicals, Inc.

Results are presented from evaluation of an intensive 1 day training program to improve the growth monitoring counseling skills of Special Supplemental Nutrition Program for Women, Infants and Children (WIC) providers. The training was framed by the patient-centered approach, and focused on a seven-step technique that emphasized eliciting client perspective on the child's health and negotiating follow-up strategies. Changes in skill were assessed during audiotaped mock counseling sessions with simulated clients. Observed intervention effects were moderate but encouraging for future training programs. After the training, more providers elicited client perspective, and provider level of engagement in negotiating with the client increased. At post-test providers asked more open-ended questions than at pre-test, and provider-to-client talk ratio decreased. Increases in provider total and competence-related satisfaction paralleled improvements in counseling proficiency. Study results suggest that counseling skills of non-physician health providers can change after a 1 day focused training: providers were more client-centered in their discussions. Limitations and implications of the study are discussed.

Laboratory innovation significantly affects program sustainability of HIV programs in low and middle income countries (LMICs) far beyond its immediate sphere of impact. Innovation in rapid development of diagnostic technologies, improved quality management systems, strengthened laboratory management, affordable external quality assurance and accreditation schemes, and building local capacity have reduced costs, brought quality improvement to point-of-care testing, increased access to testing services, reduced treatment and prevention costs and opened the door to the real possibility of ending the AIDS epidemic. However, for effectively implemented laboratory innovation to contribute to HIV quality program sustainability, it must be implemented within the overall context of the national strategic plan and HIV treatment programs. The high quality of HIV rapid diagnostic test was a breakthrough that made it possible for more persons to learn their HIV status, receive counseling, and if infected to receive treatment. Likewise, the use of dried blood spots made the shipment of samples easier for the assessment of different variables of HIV infection-molecular diagnosis, CD4+ cell counts, HIV antibodies, drug resistance surveillance, and even antiretroviral drug level measurements. Such advancement is critical for to reaching the UNAIDS target of 90-90-90 and for bringing the AIDS epidemic to an end, especially in LMICs.

The purpose of this study was to examine the effects of a facial muscle exercise program including facial massage on the facial muscle function, subjective symptoms related to paralysis and depression in patients with facial palsy. This study was a quasi-experimental research with a non-equivalent control group non-synchronized design. Participants were 70 patients with facial palsy (experimental group 35, control group 35). For the experimental group, the facial muscular exercise program including facial massage was performed 20 minutes a day, 3 times a week for two weeks. Data were analyzed using descriptive statistics, χ²-test, Fisher's exact test and independent sample t-test with the SPSS 18.0 program. Facial muscular function of the experimental group improved significantly compared to the control group. There was no significant difference in symptoms related to paralysis between the experimental group and control group. The level of depression in the experimental group was significantly lower than the control group. Results suggest that a facial muscle exercise program including facial massage is an effective nursing intervention to improve facial muscle function and decrease depression in patients with facial palsy.

A study of the effectiveness of the primary education improvement program (science) in selected schools of Northern Nigeria

NASA Astrophysics Data System (ADS)

Brown, Desmond P.; Reed, Jack A.

The Primary Education Improvement Program (Science) developed in Nigeria from 1970-1980 adopted a process approach to the teaching of science for children in Classes One and Two of primary school. In that insufficient formative data were available a study was organized to evaluate the attainment of the program's major objectives in terms of the children's ability to practice process skills. The study also attempted to measure children's interest, active participation and understanding of the lessons, as well as the availability of materials and ease of preparing and teaching the lessons for the teachers. Data were collected by means of teacher opinionnaires and a children's test to measure the attainment of process skills. The teachers who completed the opinionnaires rated the program as successful in terms of all the measured criteria. Children in the experimental and control groups were tested and their performances were compared. The results indicated that there were some significant differences in total test scores in favor of the experimental group after one year of primary school but none after two years. The program, though highly rated by teachers, did not produce the intended changes in children's behavior.

1991-01-01

In order to experimentally determine the performance of the Space Shuttle Main Engine (SSME) High Pressure Fuel Turbopump (HPFTP) turbine, a 'cold' air flow turbine test program was established at NASA's Marshall Space Flight Center. As part of this test program, a baseline test of Rocketdyne's HPFTP turbine has been completed. The turbine performance and turbine diagnostics such as airfoil surface static pressure distributions, static pressure drops through the turbine, and exit swirl angles were investigated at the turbine design point, over its operating range, and at extreme off-design points. The data was compared to pretest predictions with good results. The test data has been used to improve meanline prediction codes and is now being used to validate various three-dimensional codes. The data will also be scaled to engine conditions and used to improve the SSME steady-state performance model.

Qualitative and quantitative evaluation of academic programs can enhance the development, effectiveness, and dissemination of comparative quality reports as well as quality improvement efforts. To evaluate the five research methodology workshops through assessing participants' satisfaction, knowledge and skills gain and impact on practices by the Kirkpatrick's evaluation model. The four level Kirkpatrick's model was applied for the evaluation. Training feedback questionnaires, pre and post tests, learner development plan reports and behavioral surveys were used to evaluate the effectiveness of the workshop programs. Of the 116 participants, 28 (24.1%) liked with appreciation, 62 (53.4%) liked with suggestions and 26 (22.4%) disliked the programs. Pre and post MCQs tests mean scores showed significant improvement of relevant basic knowledge and cognitive skills by 17.67% (p ≤ 0.005). Pre-and-post tests scores on workshops sub-topics also significantly improved for the manuscripts (p ≤ 0.031) and proposal writing (p ≤ 0.834). As for the impact, 56.9% of participants started research, and 6.9% published their studies. The results from participants' performance revealed an overall positive feedback and 79% of participant reported transfer of training skills at their workplace. The course outcomes achievement and suggestions given for improvements offer insight into the program which were encouraging and very useful. Encouraging "research culture" and work-based learning are probably the most powerful determinants for research promotion. These findings therefore encourage faculty development unit to continue its training and development in the research methodology aspects.

A holistic school-based intervention for improving health-related knowledge, body composition, and fitness in elementary school students: an evaluation of the HealthMPowers program

PubMed Central

2014-01-01

Background Over the past 30 years, obesity in the United States has increased twofold in children and threefold in adolescents. In Georgia, nearly 17% of children aged 10 – 17 are obese. In response to the high prevalence of child obesity in Georgia and the potential deleterious consequences that this can have, HealthMPowers was founded in 1999 with the goal of preventing childhood obesity by improving health-enhancing behaviors in elementary schools, utilizing a holistic three-year program. This study measures the effectiveness of the HealthMPowers program in improving the school environment, student knowledge, behavior, cardiovascular fitness levels, and Body Mass Index (BMI). Methods The present analysis utilizes data from 40 schools that worked with HealthMPowers over the course of the 2012 – 2013 school year (including schools at each of the three years of the intervention period) and provided information on demographics, student knowledge and behaviors, BMI, performance on the PACER test of aerobic capacity, and school practices and policies (measured via school self-assessment with the HealthMPowers-developed instrument “Continuous Improvement Tracking Tool” or CITT), measured at the beginning and end of each school year. Paired two-sample T tests were used to compare continuous variables (e.g., student knowledge scores, BMI-for-age Z scores), while chi-squared tests were used to assess categorical variables (e.g., trichotomized PACER performance). Results Students across all grades and cohorts demonstrated improvements in knowledge and self-reported behaviors, with particularly significant improvements for third-graders in schools in the second year of the HealthMPowers program (p < 0.0001). Similarly, decreases were observed in BMI-for-Age Z scores for this cohort (and others) across grades and gender, with the most significant decreases for students overweight or obese at baseline (p < 0.0005). Students also showed significant increases in performance on the PACER test across grades and cohorts (p < 0.0001). Lastly, schools tended to improve their practices over time, as measured via the CITT instrument. Conclusions The present report demonstrates the effectiveness of the HealthMPowers program in producing positive change in school policies and practices, student knowledge and behaviors, and student fitness and BMI, supporting the use of holistic interventions to address childhood obesity.

A subscale wind tunnel test program for Orion's conical ribbon drogue parachute is under development. The desired goals of the program are to quantify aerodynamic performance of the parachute in the wake of the entry vehicle, including understanding of the coupling of the parachute and command module dynamics, and an improved understanding of the load distribution within the textile elements of the parachute. The test program is ten percent of full scale conducted in a 3x2.1 m (10x7 ft) closed loop subsonic wind tunnel. The subscale test program is uniquely suited to probing the aerodynamic and structural environment in both a quantitative and qualitative manner. Non-intrusive diagnostics, including Particle Image Velocimetry for wake velocity surveys, high speed pressure transducers for canopy pressure distribution, and a high speed photogrammetric reconstruction, will be used to quantify the parachute's performance.

Stanley, Thomas R.; Richards, Jon D.

2005-01-01

Capture-recapture methods are widely used to estimate population parameters of free-ranging animals. Closed-population capture-recapture models, which assume there are no additions to or losses from the population over the period of study (i.e., the closure assumption), are preferred for population estimation over the open-population models, which do not assume closure, because heterogeneity in detection probabilities can be accounted for and this improves estimates. In this paper we introduce CloseTest, a new Microsoft® Windows-based program that computes the Otis et al. (1978) and Stanley and Burnham (1999) closure tests for capture-recapture data sets. Information on CloseTest features and where to obtain the program are provided.

The Volunteering-in-Place (VIP) Program was developed to provide individualized meaningful volunteer activities matched to interests and capabilities for older adults with MCI in assisted living. The purposes of this single-site pre-test/post-test pilot study were to (1) establish feasibility of the VIP Program based on treatment fidelity (design, treatment, delivery, enactment); and (2) evaluate preliminary efficacy via improvement in psychological health (depressive symptoms, usefulness, purpose, resilience, and life satisfaction) and decreased sedentary activity (survey and Fitbit) at 3 and 6 months. Ten residents participated. The majority was white, female and educated, and on average 88 years old. The VIP Program was feasible and most participants continued to volunteer at 6 months. There were non-significant improvements in depressive symptoms, usefulness, purpose, resilience and recreational physical activity. The results of this study provide support for the feasibility of the VIP Program. Further study is necessary to examine efficacy. Copyright © 2016 Elsevier Inc. All rights reserved.

This study is an analysis of a workplace diabetes management program offered to employees of a Fortune 100 financial services corporation located in the United States. The 12-month worksite-based educational program was for employees who were at risk for diabetes, had prediabetes, or were diagnosed with diabetes. This employed population, with health benefits, generally had acceptable control of their diabetes at the start of the program. They statistically improved most self-efficacy measures, but improvement in biometric tests at 6 and 12 months were not significantly different from baseline. Mean hemoglobin A1c at baseline, 6 months, and 12 months was 7.2%, 7.2%, and 7.3%, respectively. At 12 months, about 40% of preprogram survey participants completed all screenings and the post-program questionnaire. Disease management programs at the workplace can be an important component in helping employees enhance their knowledge of diabetes and maintain and improve their health.

2010-01-01

The implementation of mass colorectal cancer (CRC) screening is a public health priority. Population participation is fundamental for the success of CRC screening as for any cancer screening program. The preferences of the population may influence their likelihood of participation. The authors sought to elicit population preferences for CRC screening test characteristics to improve the design of CRC screening campaigns. A discrete choice experiment was used. Questionnaires were compiled with a set of pairs of hypothetical CRC screening scenarios. The survey was conducted by mail from June 2006 to October 2006 on a representative sample of 2000 inhabitants, aged 50 to 74 years from the northwest of France, who were randomly selected from electoral lists. Questionnaires were sent to 2000 individuals, each of whom made 3 or 4 discrete choices between hypothetical tests that differed in 7 attributes: how screening is offered, process, sensitivity, rate of unnecessary colonoscopy, expected mortality reduction, method of screening test result transmission, and cost. Complete responses were received from 656 individuals (32.8%). The attributes that influenced population preferences included expected mortality reduction, sensitivity, cost, and process. Participants from high social classes were particularly influenced by sensitivity. The results demonstrate that the discrete choice experiment provides information on patient preferences for CRC screening: improving screening program effectiveness, for instance, by improving test sensitivity (the most valued attribute) would increase satisfaction among the general population with regard to CRC screening programs. Additional studies are required to study how patient preferences actually affect adherence to regular screening programs.

2017-05-01

We have made a 3-arm trial (group vs. individual exercise vs. no treatment) to test the effects of a 6-month exercise program upon the executive functions in participants with Parkinson disease. Twenty-four subjects were randomly allocated in 3 groups and undertook individualized exercises (G1, n = 8), group exercises (G2, n = 8), or monitoring (G3, n = 8). Executive functions were evaluated by means of the Wisconsin card sorting test and the Raven colored matrices, both assessed at the beginning of the program and after 6 months. The statistical analyses consisted of the application of repeated measurement tests, with a significant level of 5%. The findings showed similar behavior of groups in terms of the Wisconsin card sorting test (P = 0.792), reporting no benefit of the program on such instrument. Differently, Raven colored matrices evidenced a significant benefit provided by the intervention (P = 0.032). Compared with the control group, individuals from G1 had a substantial improvement on executive functions (P = 0.031) and from G2 had a trend of significance (P = 0.072). Findings of this study show that 6 months of exercise improved some aspects of executive functions when compared with control peers. Individual therapy seems to have a more prominent improvement than group therapy.

The purpose of this study was to test whether an interactive, web-based training program is more effective than an existing, flat-text, e-learning program at improving oral health students' knowledge, motivation, and self-efficacy to address signs of disordered eating behaviors with patients. Eighteen oral health classes of dental and dental hygiene students were randomized to either the Intervention (interactive program; n=259) or Alternative (existing program; n=58) conditions. Hierarchical linear modeling assessed for posttest differences between groups while controlling for baseline measures. Improvement among Intervention participants was superior to those who completed the Alternative program for three of the six outcomes: benefits/barriers, self-efficacy, and skills-based knowledge (effect sizes ranging from 0.43 to 0.87). This study thus suggests that interactive training programs may be better than flat-text e-learning programs for improving the skills-based knowledge and self-efficacy necessary for behavior change.

There is an evident lack of studies on the effectiveness of plyometric- and skill-based-conditioning in volleyball. This study aimed to evaluate effects of 12-week plyometric- and volleyball-skill-based training on specific conditioning abilities in female volleyball players. The sample included 41 high-level female volleyball players (21.8 ± 2.1 years of age; 1.76 ± 0.06 cm; 60.8 ± 7.0 kg), who participated in plyometric- (n = 21), or skill-based-conditioning-program (n = 20). Both programs were performed twice per week. Participants were tested on body-height, body-mass (BM), countermovement jump (CMJ), standing broad jump (SBJ), medicine ball throw, (MBT) and 20-m sprint (S20M). All tests were assessed at the study baseline (pre-) and at the end of the 12-week programs (post-testing). Two-way ANOVA for repeated measurements showed significant (p<0.05) "Group x Time" effects for all variables but body-height. Plyometric group significantly reduced body-mass (trivial effect size [ES] differences; 1% average pre- to post-measurement changes), and improved their performance in S20M (moderate ES; 8%), MBT (very large ES; 25%), CMJ (large ES; 27%), and SBJ (moderate ES; 8%). Players involved in skill-based-conditioning significantly improved CMJ (large ES; 18%), SBJ (small ES; 3%), and MBT (large ES; 9%). The changes which occurred between pre- and post-testing were more inter-correlated in plyometric-group. Although both training-modalities induced positive changes in jumping- and throwing-capacities, plyometric-training is found to be more effective than skill-based conditioning in improvement of conditioning capacities of female senior volleyball players. Future studies should evaluate differential program effects in less experienced and younger players.

Because farm labor supervisors (FLSs) are responsible for ensuring safe work environments for thousands of workers, providing them with adequate knowledge is critical to preserving worker health. Yet a challenge to offering professional training to FLSs, many of whom are foreign-born and have received different levels of education in the US and abroad, is implementing a program that not only results in knowledge gains but meets the expectations of a diverse audience. By offering bilingual instruction on safety and compliance, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) FLS Training program is helping to improve workplace conditions and professionalize the industry. A recent evaluation of the program combined participant observation and surveys to elicit knowledge and satisfaction levels from attendees of its fall 2012 trainings. Frequency distributions and dependent- and independent-means t-tests were used to measure and compare participant outcomes. The evaluation found that attendees rated the quality of their training experience as either high or very high and scored significantly better in posttraining knowledge tests than in pretraining knowledge tests across both languages. Nonetheless, attendees of the trainings delivered in English had significantly higher posttest scores than attendees of the trainings delivered in Spanish. As a result, the program has incorporated greater standardization of content delivery and staff development. Through assessment of its program components and educational outcomes, the program has documented its effectiveness and offers a replicable approach that can serve to improve the targeted outcomes of safety and health promotion in other states.

Thirty-seven test series were run utilizing a variety of drilling parameters which allowed analysis of the performance ofmore » drill bits and drilling fluids. Five different drill bit types or styles were tested: four-bladed polycrystalline diamond compact (PDC), 7-bladed PDC in regular and long profile, roller-cone, and impregnated. There were three different rock types used to simulate deep formations: Mancos shale, Carthage marble, and Crab Orchard sandstone. The testing also analyzed various drilling fluids and the extent to which they improved drilling. The PDC drill bits provided the best performance overall. The impregnated and tungsten carbide insert roller-cone drill bits performed poorly under the conditions chosen. The cesium formate drilling fluid outperformed all other drilling muds when drilling in the Carthage marble and Mancos shale with PDC drill bits. The oil base drilling fluid with manganese tetroxide weighting material provided the best performance when drilling the Crab Orchard sandstone.« less

Improved Testing Capability and Adaptability Through the Use of Wireless Sensors

Solano, Wanda M.

2003-01-01

From the first Saturn V rocket booster (S-II-T) testing in 1966 and the routine Space Shuttle Main Engine (SSME) testing beginning in 1975, to more recent test programs such as the X-33 Aerospike Engine, the Integrated Powerhead Development (IPD) program, and the Hybrid Sounding Rocket (HYSR), Stennis Space Center (SSC) continues to be a premier location for conducting large-scale testing. Central to each test program is the capability for sensor systems to deliver reliable measurements and high quality data, while also providing a means to monitor the test stand area to the highest degree of safety and sustainability. Sensor wiring is routed along piping and through cable trenches, making its way from the engine test area, through the test stand area and to the signal conditioning building before final transfer to the test control center. When sensor requirements lie outside the reach of the routine sensor cable routing, the use of wireless sensor networks becomes particularly attractive due to their versatility and ease of installation. As part of an on-going effort to enhance the testing capabilities of Stennis Space Center, the Test Technology and Development group has found numerous applications for its sensor-adaptable wireless sensor suite. While not intended for critical engine measurements or control loops, in-house hardware and software development of the sensor suite can provide improved testing capability for a range of applications including the safety monitoring of propellant storage barrels and as an experimental test-bed for embedded health monitoring paradigms.

Improved handling qualities of fighter aircraft at high angles of attack can be provided by various stability and control augmentation techniques. NASA and the U.S. Navy are conducting a joint flight demonstration of these techniques on an F-14 airplane. This paper reports on the flight test experience with a newly designed lateral-directional control system which suppresses such high angle of attack handling qualities problems as roll reversal, wing rock, and directional divergence while simultaneously improving departure/spin resistance. The technique of integrating a piloted simulation into the flight program was used extensively in this program. This technique had not been applied previously to high angle of attack testing and required the development of a valid model to simulate the test airplane at extremely high angles of attack.

FFTF Passive Safety Test Data for Benchmarks for New LMR Designs

DOE Office of Scientific and Technical Information (OSTI.GOV)

Wootan, David W.; Casella, Andrew M.

Liquid Metal Reactors (LMRs) continue to be considered as an attractive concept for advanced reactor design. Software packages such as SASSYS are being used to im-prove new LMR designs and operating characteristics. Significant cost and safety im-provements can be realized in advanced liquid metal reactor designs by emphasizing inherent or passive safety through crediting the beneficial reactivity feedbacks associ-ated with core and structural movement. This passive safety approach was adopted for the Fast Flux Test Facility (FFTF), and an experimental program was conducted to characterize the structural reactivity feedback. The FFTF passive safety testing pro-gram was developed to examine howmore » specific design elements influenced dynamic re-activity feedback in response to a reactivity input and to demonstrate the scalability of reactivity feedback results to reactors of current interest. The U.S. Department of En-ergy, Office of Nuclear Energy Advanced Reactor Technology program is in the pro-cess of preserving, protecting, securing, and placing in electronic format information and data from the FFTF, including the core configurations and data collected during the passive safety tests. Benchmarks based on empirical data gathered during operation of the Fast Flux Test Facility (FFTF) as well as design documents and post-irradiation examination will aid in the validation of these software packages and the models and calculations they produce. Evaluation of these actual test data could provide insight to improve analytical methods which may be used to support future licensing applications for LMRs« less

Lewicki, David G.; Decker, Harry J.; Shimski, John T.

1992-01-01

Experimental tests were performed on the OH-58A helicopter main rotor transmission in the NASA Lewis 500-hp Helicopter Transmission Test Stand. The testing was part of a joint Navy/NASA/Army lubrication program. The objective of the program was to develop a separate lubricant for gearboxes and demonstrate an improved performance in life and load-carrying capacity. The goal of the experiments was to develop a testing procedure to fail certain transmission components using a MIL-L-23699 base reference oil, then run identical tests with improved lubricants and demonstrate performance. The tests were directed at failing components that the Navy has had problems with due to marginal lubrication. These failures included mast shaft bearing micropitting, sun gear and planet bearing fatigue, and spiral bevel gear scoring. A variety of tests were performed and over 900 hours of total run time accumulated for these tests. Some success was achieved in developing a testing procedure to produce sun gear and planet bearing fatigue failures. Only marginal success was achieved in producing mast shaft bearing micropitting and spiral bevel gear scoring.

Patients with CKD have a high prevalence of cardiovascular disease associated with or exacerbated by inactivity. This randomized, controlled study investigated whether a renal rehabilitation exercise program for patients with stages 3 or 4 CKD would improve their physical function and quality of life. In total, 119 adults with CKD stages 3 and 4 were randomized, and 107 of these patients proceeded to usual care or the renal rehabilitation exercise intervention consisting of usual care plus guided exercise two times per week for 12 weeks (24 sessions). Physical function was determined by three well established performance-based tests: 6-minute walk test, sit-to-stand test, and gait-speed test. Health-related quality of life was assessed by the RAND 36-Item Short Form Health Survey. At baseline, no differences in self-reported level of activity, 6-minute walk test, and sit-to-stand test scores were observed between the usual care (n=48) and renal rehabilitation exercise (n=59) groups, although baseline gait-speed test score was higher in the renal rehabilitation exercise group (P<0.001). At follow-up, the renal rehabilitation exercise group but not the usual care group showed significant improvements in the 6-minute walk test (+210.4±266.0 ft [19% improvement] versus -10±219.9 ft; P<0.001), the sit-to-stand test (+26.9±27% of age prediction [29% improvement] versus +0.7±12.1% of age prediction; P<0.001), and the RAND-36 physical measures of role functioning (P<0.01), physical functioning (P<0.01), energy/fatigue levels (P=0.01), and general health (P=0.03) and mental measure of pain scale (P=0.04). The renal rehabilitation exercise regimen was generally well tolerated. A 12-week/24-session renal rehabilitation exercise program improved physical capacity and quality of life in patients with CKD stages 3 and 4. Longer follow-up is needed to determine if these findings will translate into decreased mortality rates. Copyright © 2014 by the American Society of Nephrology.

2013-06-01

Diabetes in elderly adults is associated with an increased risk of fall. The aim of study was to determine whether a virtual reality exercise (VRE) program would improve balance, strength, gait, and falls efficacy in elderly adults with diabetes. Fifty-five subjects with diabetes mellitus over 65 years of age were randomly assigned to a VRE group (VREG) (n=27) and a control group (CG) (n=28). The VREG received the VRE program and diabetes education, whereas the CG received only the diabetes education. The VRE program used video gaming (PlayStation(®) 2; Sony, Tokyo, Japan) and was conducted for 50 min twice a week for 10 weeks. Balance, muscle strength, gait, and falls efficacy were measured at baseline and after intervention. Measurements were taken using a clinical tests (the one-leg-standing test, the Berg Balance Scale, the functional reach test, the timed up-and-go test, and the sit-to-stand test), and gait analysis. A self-administered questionnaire was used to measure falls efficacy. After training, the VREG showed significantly improved balance, decreased sit-to-stand times, and increased gait speed, cadence, and falls efficacy. The VRE program was to maximize the effects of exercise by triggering players was to be fully immersed into the games and enhanced major influential factors on the falls of subject. This study suggests VRE programs are feasible and effective for reduced the risk of falls in elderly adults with type 2 diabetes.

Francis, Sarah L; Taylor, Martha L

2009-12-01

Social Marketing Theory is a comprehensive approach of program development encompassing the needs and preferences of the intended audience. It was hypothesized a Social Marketing Theory-based, registered dietitian-led, in-home, cardiovascular disease-targeted diet-education program would improve the dietary status of community-residing older women. Using a randomized control group design, this 90-day program in two North Carolina counties included 58 women (30 control; 28 intervention) ages 54 to 83 years. Data were collected using the Mini Nutritional Assessment, three 3-day food records, and program evaluations. The intervention group received two individual registered dietitian-led in-home education sessions and the control group received education material mailings (Visits 2 and 3). Pretested education materials were used. Visits/mailings were scheduled 28 to 30 days apart. Variables measured included cardiovascular disease-related dietary practices and dietary status (Mini Nutritional Assessment). Data were analyzed using descriptive statistics, paired sample t tests, multivariant analyses, and independent t tests. Intervention and control Mini Nutritional Assessment scores improved (P=0.0001). Intervention subjects consumed more fiber than control (P=0.013) and reduced sodium intake (P=0.02). Controls reduced energy (P=0.01) and cholesterol intakes (P=0.029), likely because of the decreased food intake. The majority (n=51, 87.9%) rated the program as good to excellent and almost all (n=55, 94.8%) would recommend the program to a friend. The most popular features of the program were the individualized sessions (n=20, 34.5%) and diet analyses (n=11, 19%). These results suggest that cardiovascular disease diet-education materials utilizing Social Marketing Theory principles can lead to improved dietary status among community-residing older women.

Brown, David B.

1990-01-01

The results of research and development efforts are described for Task one, Phase two of a general project entitled The Development of a Program Analysis Environment for Ada. The scope of this task includes the design and development of a prototype system for testing Ada software modules at the unit level. The system is called Query Utility Environment for Software Testing of Ada (QUEST/Ada). The prototype for condition coverage provides a platform that implements expert system interaction with program testing. The expert system can modify data in the instrument source code in order to achieve coverage goals. Given this initial prototype, it is possible to evaluate the rule base in order to develop improved rules for test case generation. The goals of Phase two are the following: (1) to continue to develop and improve the current user interface to support the other goals of this research effort (i.e., those related to improved testing efficiency and increased code reliable); (2) to develop and empirically evaluate a succession of alternative rule bases for the test case generator such that the expert system achieves coverage in a more efficient manner; and (3) to extend the concepts of the current test environment to address the issues of Ada concurrency.

Prenatal and infancy home visiting by nurses: from randomized trials to community replication.

PubMed

Olds, David L

2002-09-01

This paper summarizes a 25-year program of research that has attempted to improve the early health and development of low-income mothers and children and their future life trajectories with prenatal and infancy home visiting by nurses. The program has been tested in two separate large-scale randomized controlled trials with different populations living in different contexts. The program has been successful in improving parental care of the child as reflected in fewer injuries and ingestions that may be associated with child abuse and neglect; and maternal life-course, reflected in fewer subsequent pregnancies, greater work force participation, and reduced use of public assistance and food stamps. In the first trial, the program also produced long-term effects on the number of arrests, convictions, emergent substance use, and promiscuous sexual activity of 15-year-old children whose nurse-visited mothers were low-income and unmarried when they registered in the study during pregnancy. Since 1996, the program has been offered for public investment outside of research contexts. Careful attention has been given to ensuring that the program is replicated with fidelity to the model tested in the scientifically controlled studies by working with community leaders to ensure that organization and community contexts are favorable for the program; by providing the nurses with excellent training and technical assistance and detailed visit-by-visit guidelines; and by providing organizations with a web-based clinical information system that creates a basis for monitoring program performance and continuous quality improvement.

Cardiovascular program to improve physical fitness in those over 60 years old – pilot study

PubMed Central

Castillo-Rodríguez, Alfonso; Chinchilla-Minguet, José Luis

2014-01-01

Background In Spain, more than 50% of 60-year-olds are obese. Obesity is a disease with serious cardiovascular risks. The mortality rate for cardiovascular disease in Spain is 31.1%. Objectives To improve aerobic fitness, strength, flexibility and balance, and body composition (BC) in persons over 60 years old. Materials and methods A clinical intervention study of 24 participants was carried out over a period of 3 months. Aerobic fitness was assessed using the Rockport 1-Mile Walk Test. Upper-body strength was evaluated with an ad hoc test. Flexibility and balance were evaluated using the Sit and Reach Test and the Stork Balance Stand Test, respectively. Anthropometric measurements were taken by bioelectrical impedance. Results After 3 months of training, aerobic fitness was improved, as demonstrated by improved test times (pretest 13.04 minutes, posttest 12.13 minutes; P<0.05). Body composition was also improved, but the results were not statistically significant (fat mass pretest 31.58%±5.65%, posttest 30.65%±6.31%; skeletal muscle mass pretest 43.99±9.53 kg, posttest 46.63±10.90 kg). Conclusion Our data show that in subjects over 60 years old, aerobic fitness was improved due to program intervention. However, these results should be treated with caution, because of the limited sample size and the brief time period of this pilot study. A more rigorous study would include a sample of at least 100 participants. PMID:25143714

Orme, John S.; DeLaat, John C.; Southwick, Robert D.; Gallops, George W.; Doane, Paul M.

1998-01-01

Flight tests were recently completed to demonstrate an inlet-distortion-tolerant engine control system. These flight tests were part of NASA's High Stability Engine Control (HISTEC) program. The objective of the HISTEC program was to design, develop, and flight demonstrate an advanced integrated engine control system that uses measurement-based, real-time estimates of inlet airflow distortion to enhance engine stability. With improved stability and tolerance of inlet airflow distortion, future engine designs may benefit from a reduction in design stall-margin requirements and enhanced reliability, with a corresponding increase in performance and decrease in fuel consumption. This paper describes the HISTEC methodology, presents an aircraft test bed description (including HISTEC-specific modifications) and verification and validation ground tests. Additionally, flight test safety considerations, test plan and technique design and approach, and flight operations are addressed. Some illustrative results are presented to demonstrate the type of analysis and results produced from the flight test program.

The use of a mobile health care application, the delivery of health care or health care-related services through the use of portable devices, to manage functional loss, treatment-related toxicities, and impaired quality of life in cancer patients during chemotherapy through supervised self-management has been increasing. The aim of the present study was to evaluate the efficacy and feasibility of comprehensive mobile health care using a tailored rehabilitation program for colorectal cancer patients undergoing active chemotherapy. A total of 102 colorectal cancer patients undergoing chemotherapy underwent 12 weeks of smartphone aftercare through provision of a mobile application and wearable device that included a rehabilitation exercise program and information on their disease and treatment. The grip strength test, 30-second chair stand test, 2-minute walk test, amount of physical activity (International Physical Activity Questionnaire short-form), quality of life (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30), and nutritional status (Patient-generated Subjective Global Assessment) were assessed and measured at baseline, at mid-intervention (6 weeks), and at completion of the intervention (12 weeks). The rehabilitation exercise intensity was adjusted by the test results at every assessment and through real-time communication between the patients and clinicians. Of the 102 patients, 75 completed all 12 weeks of the smartphone aftercare rehabilitation program. The lower extremity strength (P < .001) and cardiorespiratory endurance (P < .001) was significantly improved. Fatigue (P < .007) and nausea/vomiting (P < .040) symptoms were significantly relieved after the program. A tailored rehabilitation exercise program provided through a comprehensive mobile health care application was effective in improving patients' physical capacity and treatment-related symptoms even during active chemotherapy.

Whalen, Thomas J.

1988-01-01

This is the third annual technical report for the program entitled, Improved Silicon Carbide for Advanced Heat Engines, for the period February 16, 1987 to February 15, 1988. The objective of the original program was the development of high strength, high reliability silicon carbide parts with complex shapes suitable for use in advanced heat engines. Injection molding is the forming method selected for the program because it is capable of forming complex parts adaptable for mass production on an economically sound basis. The goals of the revised program are to reach a Weibull characteristic strength of 550 MPa (80 ksi) and a Weibull modulus of 16 for bars tested in 4-point loading. Two tasks are discussed: Task 1 which involves materials and process improvements, and Task 2 which is a MOR bar matrix to improve strength and reliability. Many statistically designed experiments were completed under task 1 which improved the composition of the batches, the mixing of the powders, the sinter and anneal cycles. The best results were obtained by an attritor mixing process which yielded strengths in excess of 550 MPa (80 ksi) and an individual Weibull modulus of 16.8 for a 9-sample group. Strengths measured at 1200 and 1400 C were equal to the room temperature strength. Annealing of machined test bars significantly improved the strength. Molding yields were measured and flaw distributions were observed to follow a Poisson process. The second iteration of the Task 2 matrix experiment is described.

After stroke, many individuals lack resources to receive the intensive rehabilitation that is thought to improve upper extremity motor function. This case study describes the application of a telerehabilitation intervention using a portable robotic device combined with a home exercise program (HEP) designed to improve upper extremity function. The participant was a 54-year-old man, 22 weeks following right medullary pyramidal ischemic infarct. At baseline, he exhibited residual paresis of the left upper extremity, resulting in impaired motor control consistent with a flexion synergistic pattern, scoring 22 of 66 on the Fugl-Meyer Assessment. The participant completed 85 total hours of training (38 hours of robotic device and 47 hours of HEP) over the 8-week intervention period. The participant demonstrated an improvement of 26 points on the Action Research Arm Test, 5 points on the Functional Ability Scale portion of the Wolf Motor Function Test, and 20 points on the Fugl-Meyer Assessment, all of which surpassed the minimal clinically important difference. Of the 17 tasks of the Wolf Motor Function Test, he demonstrated improvement on 11 of the 15 time-based tasks and both strength measures. The participant reported an overall improvement in his recovery from stroke on the Stroke Impact Scale quality-of-life questionnaire from 40 of 100 to 65 of 100. His score on the Center for Epidemiologic Studies Depression Scale improved by 19 points. This case demonstrates that robotic-assisted therapy paired with an HEP can be successfully delivered within a home environment to a person with stroke. Robotic-assisted therapy may be a feasible and efficacious adjunct to an HEP program to elicit substantial improvements in upper extremity motor function, especially in those persons with stroke who lack access to stroke rehabilitation centers.

This study investigated the effects of group music therapy on improving anxiety, depression, and self-esteem in Chinese prisoners. Two-hundred male prisoners were randomly assigned to music therapy (n = 100) or standard care (n = 100). The music therapy had 20 sessions of group therapy compared with standard care. Anxiety (State and Trait Anxiety Inventory [STAI]), depression (Beck Depression Inventory [BDI]), and self-esteem (Texas Social Behavior Inventory [TSBI], Rosenberg Self-Esteem Inventory [RSI]) were measured by standardized scales at baseline, mid-program, and post-program. Data were analyzed based on the intention to treat principle. Compared with standard care, anxiety and depression in the music therapy condition decreased significantly at mid-test and post-test; self-esteem improved significantly at mid-test (TSBI) and at post-test (TSBI, RSI). Improvements were greater in younger participants (STAI-Trait, RSI) and/or in those with a lower level of education (STAI-State, STAI-Trait). Group music therapy seems to be effective in improving anxiety, depression, and self-esteem and was shown to be most beneficial for prisoners of younger age or with lower education level. © The Author(s) 2015.

NASA-Ames' Highly Integrated Digital Electronic Control (HIDEC) flight test program aims to develop fully integrated airframe, propulsion, and flight control systems. The HIDEC F-15 adaptive engine control system flight test program has demonstrated that significant performance improvements are obtainable through the retention of stall-free engine operation throughout the aircraft flight and maneuver envelopes. The greatest thrust increase was projected for the medium-to-high altitude flight regime at subsonic speed which is of such importance to air combat. Adaptive engine control systems such as the HIDEC F-15's can be used to upgrade the performance of existing aircraft without resort to expensive reengining programs.

Dysarthia is a common sequela of cerebral palsy (CP), directly affecting both the intelligibility of speech and the child's psycho-social adjustment. Speech therapy focused exclusively on the articulatory organs does not always help CP children to speak more intelligibly. The program of art therapy described here has proven to be helpful for these children. From among all the CP children enrolled in our art therapy program from 2005 to 2009, we selected a group of 14 boys and girls (average age 15.3) with severe dysarthria at baseline but no other language or cognitive disturbances. Our retrospective study was based on results from the Auditory Dysarthria Scale and neuropsychological tests for fluency, administered routinely over the 4 months of art therapy. All 14 children in the study group showed some degree of improvement after art therapy in all tested parameters. On the Auditory Dysarthia Scale, highly significant improvements were noted in overall intelligibility (p<0.0001), with significant improvement (p<0.001) in volume, tempo, and control of pauses. The least improvement was noted in the most purely motor parameters. All 14 children also exhibited significant improvement in fluency. Art therapy improves the intelligibility of speech in children with cerebral palsy, even when language functions are not as such the object of therapeutic intervention.

We evaluated the effectiveness of the Salud y Bienestar program to deliver diabetes education in the Hispanic population in the United States. This program uses a community outreach model where community health promoters are trained and then they deliver education to other community members regarding diabetes disease, risk factors, and ways to prevent and control disease. This intervention applies a one-group pre- and post-test design to improve diabetes knowledge. The intervention carried out in the states of California, Texas, and Washington DC. A total of 1,413 participants were enrolled. Of these, 73% were females, 46% were 65 years or older, 59% were Mexican, 64% had at least elementary education, 56% had lived in the US for more than 20 years, and 38% participants were self-reported diabetic. Among diabetic participants, a significant improvement was observed on diabetes knowledge when comparing pre- and post-test scores (13.7 vs. 18.6, P < 0.001; Cohen's d = 1.2). Among non-diabetic participants, diabetes knowledge also increased significantly after one-single training session (12.9 vs. 18.2, P < 0.001; Cohen's d = 1.2). The Salud y Bienestar program conducted by community health workers was effective approach to improving diabetes knowledge in the Hispanic population.

Of the 125 species initially evaluated for SRIC, 20 are being seriously considered with most of emphasis on 16 hardwood species. Range-wide seed collections of 12 species were provenance tested; these include Platanus occidentalis (sycamore), Alnus glutinosa (European black alder), and Robinia pseudoacacia (black locust). Based on the results of these tests, highly productive, site-specific seed sources are being chosen for several geographic regions. Three of these species re currently being bred for increased productivity in SRIC systems. Genetic improvementmore » is viewed as a tool for increasing productivity, having anticipated gains of 40 to 50%. The techniques of somaclonal screening and genetic engineering are being evaluated for their usefulness in the SRIC improvement program. Currently, salt-tolerant Atriplex canescens (four-wing saltbush) and herbicide-resistant Populus spp. are being sought via somaclonal screening. 35 refs., 4 figs., 3 tabs.« less

Recent advances in assay technology have led to major improvements in how HIV-1 neutralizing antibodies are measured. A luciferase reporter gene assay performed in TZM-bl (JC53bl-13) cells has been optimized and validated. Because this assay has been adopted by multiple laboratories worldwide, an external proficiency testing program was developed to ensure data equivalency across laboratories performing this neutralizing antibody assay for HIV/AIDS vaccine clinical trials. The program was optimized by conducting three independent rounds of testing, with an increased level of stringency from the first to third round. Results from the participating domestic and international laboratories improved each round as factors that contributed to inter-assay variability were identified and minimized. Key contributors to increased agreement were experience among laboratories and standardization of reagents. A statistical qualification rule was developed using a simulation procedure based on the three optimization rounds of testing, where a laboratory qualifies if at least 25 of the 30 ID50 values lie within the acceptance ranges. This ensures no more than a 20% risk that a participating laboratory fails to qualify when it should, as defined by the simulation procedure. Five experienced reference laboratories were identified and tested a series of standardized reagents to derive the acceptance ranges for pass-fail criteria. This Standardized Proficiency Testing Program is the first available for the evaluation and documentation of assay equivalency for laboratories performing HIV-1 neutralizing antibody assays and may provide guidance for the development of future proficiency testing programs for other assay platforms.

Background Rapid Diagnostic Tests (RDTs) for Ebola Virus Disease (EVD) at the point of care have the potential to increase access and acceptability of EVD testing and the speed of patient isolation and secure burials for suspect cases. A pilot program for EVD RDTs in high risk areas of Guinea was introduced in October 2015. This paper presents concordance data between EVD RDTs and PCR testing in the field as well as an assessment of the acceptability, feasibility, and quality assurance of the RDT program. Methods and findings Concordance data were compiled from laboratory surveillance databases. The operational measures of the laboratory-based EVD RDT program were evaluated at all 34 sentinel sites in Guinea through: (1) a technical questionnaire filled by the lab technicians who performed the RDTs, (2) a checklist filled by the evaluator during the site visits, and (3) direct observation of the lab technicians performing the quality control test. Acceptability of the EVD RDT was good for technicians, patients, and families although many technicians (69.8%) expressed concern for their safety while performing the test. The feasibility of the program was good based on average technician knowledge scores (6.6 out of 8) but basic infrastructure, equipment, and supplies were lacking. There was much room for improvement in quality assurance of the program. Conclusions The implementation of new diagnostics in weak laboratory systems requires general training in quality assurance, biosafety and communication with patients in addition to specific training for the new test. Corresponding capacity building in terms of basic equipment and a long-term commitment to transfer supervision and quality improvement to national public health staff are necessary for successful implementation.

This paper evaluates Responsible Choices for Men, a 14-week therapy group for abusive men based on feminist perspectives using narrative methods. Pre-test and post-test information was available for 76 program completers measuring physical and non-physical abuse, self-esteem, perceived stress, family relations, depression, assertiveness, and sex-role beliefs. The men significantly improved on all variables. A further focus was following up with 22 group members, contacted 5 to 28 months post treatment and asked to complete the same measures. The results indicated not only maintenance of the post-group changes, but continued improvement. Clinical implications and recommendations for group programming with abusive men are presented.

This study combined quantitative and qualitative research methods to evaluate quality-of-life changes in drug-dependent patients after participation in a group-based exercise program. Quality of life (SF-36) and physical fitness (six-minute Walk Test, Timed Get Up and Go Test, and Chair Stand Test) were quantitatively determined in a group (n=37) of drug-dependent patients before and after a 12-week group exercise program (n=18) or routine care (n=19). Additionally, in-depth interviews were conducted at the end of the program with a subsample of 11 participants from the exercise group. Quantitative results showed improvements in fitness and different aspects of quality of life, such as physical function, mental health, vitality, social function, and general health perception. Qualitative results showed specific physical benefits (decreased injuries and muscle pain, decreased weight, and increased vitality with improvement in activities of daily living), psychological benefits (forgetting about everyday problems, improved mood, decreased stress and anxiety), social benefits, and a reduction in craving. The results of this study provide insight into the importance of exercise for the quality of life and recovery process of drug-dependent patients.

Traditional exercise programs for older adults, which focus on aerobic and strength training, have had only modest effects on walking. Recently, a motor learning exercise program was shown to have greater effects on walking compared with a traditional exercise program. Translating this novel motor learning exercise program into a group exercise program would allow it to be offered as an evidence-based, community-based program for older adults. To translate a walking rehabilitation program based on motor learning theory from one-on-one to group delivery (On the Move) and evaluate multiple aspects of implementation in older adults with impaired mobility. The translation process involved multiple iterations, including meetings of experts in the field (Phase I), focus groups (Phase II), and implementation of the newly developed program (Phase III). Phase III was based on a one-group model of intervention development for feasibility, safety, potential effects, and acceptability. Community sites, including 2 independent living facilities, an apartment building, and a community center. Adults 65 years of age or older who could ambulate independently and who were medically stable. Thirty-one adults, mean age 82.3 ± 5.6 years, were eligible to participate. The group exercise program was held twice a week for 12 weeks. Acceptability of the program was determined by retention and adherence rates and a satisfaction survey. Risk was measured by adverse events and questions on perceived challenge and safety. Mobility was assessed pre- and postintervention by gait speed, Figure of 8 Walk Test, and 6-minute walk test. Modifications to the program included adjustments to format/length, music, education, and group interaction. The 12-week program was completed by 24 of 31 entrants (77%). Adherence was high, with participants attending on average 83% of the classes. Safety was excellent, with only 1 subject experiencing a controlled, noninjurious fall. There was preliminary evidence for improved mobility after the intervention: gait speed improved from 0.76 ± 0.21 to 0.81 ± 0.22 m/s, P = .06; Figure of 8 Walk Test from 13.0 ± 3.9 to 12.0 ± 3.9 seconds, P = .07; and 6-minute walk test from 246 ± 75 to 281 ± 67 m, P = .02. The group-based program was safe and acceptable to older adults with impaired mobility and resulted in potentially clinically meaningful improvements in mobility.

The Heavy Hydrocarbon Main Injector Program was an analytical, design, and test program to demonstrate an injection concept applicable to an Isolated Combustion Compartment of a full-scale, high pressure, LOX/RP-1 engine. Several injector patterns were tested in a 3.4-in. combustor. Based on these results, features of the most promising injector design were incorporated into a 5.7-in. injector which was then hot-fire tested. In turn, a preliminary design of a 5-compartment 2D combustor was based on this pattern. Also the additional subscale injector testing and analysis was performed with an emphasis on improving analytical techniques and acoustic cavity design methodology. Several of the existing 3.5-in. diameter injectors were hot-fire tested with and without acoustic cavities for spontaneous and dynamic stability characteristics.

This study investigates the effect of synchronized metronome training (SMT) on motor timing and how this training might affect golf shot accuracy. Twenty-six experienced male golfers participated (mean age 27 years; mean golf handicap 12.6) in this study. Pre- and post-test investigations of golf shots made by three different clubs were conducted by use of a golf simulator. The golfers were randomized into two groups: a SMT group and a Control group. After the pre-test, the golfers in the SMT group completed a 4-week SMT program designed to improve their motor timing, the golfers in the Control group were merely training their golf-swings during the same time period. No differences between the two groups were found from the pre-test outcomes, either for motor timing scores or for golf shot accuracy. However, the post-test results after the 4-weeks SMT showed evident motor timing improvements. Additionally, significant improvements for golf shot accuracy were found for the SMT group and with less variability in their performance. No such improvements were found for the golfers in the Control group. As with previous studies that used a SMT program, this study’s results provide further evidence that motor timing can be improved by SMT and that such timing improvement also improves golf accuracy. Key points This study investigates the effect of synchronized metronome training (SMT) on motor timing and how this training might affect golf shot accuracy. A randomized control group design was used. The 4 week SMT intervention showed significant improvements in motor timing, golf shot accuracy, and lead to less variability. We conclude that this study’s results provide further evidence that motor timing can be improved by SMT training and that such timing improvement also improves golf accuracy. PMID:24149608

Palliative care education for health care professionals is a key element in improving access to quality palliative care. The Palliative Care Emphasis Program on Symptom Management and Assessment for Continuous Medical Education (PEACE) was designed to provide educational opportunities for all physicians in Japan. As of 2015, 57,764 physicians had completed it. The objective of this study was to estimate the effects of the program. This study was an analysis of 2 nationwide observational studies from 2008 and 2015. We conducted 2 questionnaire surveys for representative samples of physicians. The measurements used were the Palliative Care Knowledge Test (range, 0-100) and the Palliative Care Difficulties Scale (range, 1-4). Comparisons were made with the unpaired Student t test and with a multivariate linear regression model using 2 cohorts and a propensity score-matched sample. This study analyzed a total of 48,487 physicians in 2008 and a total of 2720 physicians in 2015. Between 2008 and 2015, physicians' knowledge and difficulties significantly improved on the Palliative Care Knowledge Test with total scores of 68 and 78, respectively (P < .001; effect size, 0.40) and on the Palliative Care Difficulties Scale with total scores of 2.65 and 2.49, respectively (P < .001; effect size, 0.29). Propensity-score matching resulted in 619 untrained physicians matched to 619 trained physicians, and physicians who trained with the PEACE program had a higher knowledge score (74 vs 86; P < .001; effect size, 0.64) and a lower difficulties score (2.6 vs 2.3; P < .001; effect size, 0.42). Physicians' knowledge of and difficulties with palliative care improved on a national level. The PEACE program may have contributed to these improvements.

Although suggestions are that benefits of relationship and marriage education (RME) participation extend from the interparental relationship with parenting and child outcomes, few evaluation studies of RME test these assumptions and the relationship among changes in these areas. This quasi-experimental study focuses on a parallel process growth model that tests a spillover hypothesis of program effects and finds, in a sample of low-income minority mothers with a child attending a Head Start program, that increases in mother reports of coparenting agreement for RME participants predict decreases in their reports of punitive parenting behaviors. Although improvements in parenting behaviors did not predict increases in teacher reports of children's social competence, improvements in coparenting agreement were associated with increases in children's social competence over time. In addition, comparative tests of outcomes between parents in the program and parents in a comparison group reveal that RME program participants (n = 171) demonstrate significant improvements compared to nonparticipants (n = 143) on coparenting agreement, parenting practices, and teachers' reports of preschool children's social competence over a 1 year period. The findings are offered as a step forward in better understanding the experiences of low-resource participants in RME.

This study was done to evaluate the Military Mental Health Promotion Program. The program was an email based cognitive behavioral intervention. The research design was a quasi-experimental study with a non-equivalent control group pretest-posttest design. Participants were 32 soldiers who agreed to participate in the program. Data were collected at three different times from January 2012 to March 2012; pre-test, post-test, and a one-month follow-up test. The data were statistically analyzed using SPSS 18.0. The effectiveness of the program was tested by repeated measures ANOVA. The first hypothesis that the level of depression in the experimental group who participated in the program would decrease compared to the control group was not supported in that the difference in group-time interaction was not statistically significant (F=2.19, p=.121). The second and third hypothesis related to anxiety and self-esteem were supported in group-time interaction, respectively (F=7.41, p=.001, F=11.67, p<.001). Results indicate that the program is effective in improving soldiers' mental health status in areas of anxiety and self-esteem.

Caregivers of patients with heart failure experience burden and negative health outcomes. Adequate support for family caregivers improves their well-being and the quality of care provided to the patients. However, little is known about the benefits of interventions for caregivers of patients with heart failure in China. To test the effects of a multidisciplinary supportive program for family caregivers on caregiver burden, quality of life, and depression. A randomized controlled design with repeated measures was used in this study. A total of 118 participants were randomized into experimental (n=59) and control groups (n=59) from May to December 2014 in one hospital in Chengdu, People's Republic of China. Participants in the experimental group received a 3-month multidisciplinary supportive program, consisting of three 60-min sessions of group classes, three 30-min peer support groups, and regular telephone follow-ups and consultations, while participants in the control group received usual care only. Outcomes were caregiver burden, quality of life, and depression. Data were collected at baseline, post-test (3 months after discharge), and 3 months after post-test (6 months after discharge). The repeated measures analysis of variance was used to examine the effects of groups, changes over time, and time-group interaction on outcome variables. There were significant improvements in caregiver burden, mental health, and depression after post-test and 3 months after post-test in the experimental group. However, there was no significant improvement in caregivers' physical health at either 3 or 6 months following discharge. A multidisciplinary supportive program for caregivers of heart failure patients had positive effects and provides a unique perspective of an intervention considering Chinese culture and customs.

The objective of this study was to investigate the benefits of a low-volume out-patient whole-body vibration training (WBVT) program on exercise capacity in comparison with a calisthenics training program in subjects with COPD. In this single-center randomized controlled trial, 29 subjects with mild to severe COPD were randomized to WBVT or to calisthenics training, including relaxation and breathing retraining in combination with calisthenics exercises. Both groups equally exercised for a duration of 3 months with 2 sessions of 30 min/week. Outcome parameters were 6-min walk distance (6MWD, primary outcome), 5-repetition sit-to-stand test, leg press peak force, Berg balance scale, St George Respiratory Questionnaire, and COPD assessment test. Twenty-seven subjects completed the study (WBVT, n = 14; calisthenics training program, n = 13). Baseline characteristics between groups were comparable. Subjects in the WBVT group significantly improved median (interquartile range) 6MWD (+105 [45.5-133.5] m, P = .001), sit-to-stand test (-2.3 [-3.1 to -1.3] s, P = .001), peak force (28.7 [16.7-33.3] kg, P = .001), and Berg balance scale (1.5 [0.0-4.0] points, P = .055). Changes in 6MWD, sit-to-stand test, and leg press peak force were also found to be significantly different between groups in favor of the WBVT group. Only the between-group difference of the COPD assessment test score was in favor of the calisthenics training group ( P = .02). A low-volume WBVT program resulted in significantly and clinically relevant larger improvements in exercise capacity compared with calisthenics exercises in subjects with mild to severe COPD.

2016-04-01

This study was designed to examine whether a school-wide antibullying program, effective in reducing incidents of bullying, can also reduce the harm associated with victimization. Specifically, we test whether baseline victimization moderates the KiVa program intervention effects on school perceptions, depression, and self-esteem. Relying on a randomized control sample consisting of 7,010 fourth to sixth grade Finnish elementary school students, self-report data were examined using multilevel modeling across 39 intervention and 38 control schools over a 12-month period. The KiVa program was particularly effective in facilitating perceptions of a caring school climate among students who were most victimized before the intervention, while program benefits on attitudes toward school did not vary by level of victimization. The intervention effects on depression and self-esteem were strongest only among the most victimized sixth graders. The results suggest that antibullying programs designed to improve the school ecology can alleviate the plight of the victimized and underscore that harm reduction should be assessed by testing risk × intervention effects when evaluating effectiveness of such programs.

To determine the effectiveness of the Contra Caries Oral Health Education Program (CCOHEP) for improving low-income, Spanish-speaking parents' oral health knowledge and behaviors for their young children. Mexican American children in the United States suffer disproportionately high prevalence and severity of early childhood caries, yet few evaluated, theory-based behavioral interventions exist for this population. CCOHEP is a theory-based curriculum consisting of four 2-h interactive classes designed for and by Spanish speakers and led by designated community health educators (promotoras). Topics included children's oral hygiene, caries etiology, dental procedures, nutrition, child behavior management, and parent skill-building activities. Low-income Spanish-speaking parents/caregivers of children aged 0-5 years were recruited through community services in an agricultural city in California. Survey questions from the Oral Health Basic Research Facts Questionnaire measuring oral health-related behaviors and knowledge were verbally administered before, immediately after, and 3 months after attendance at CCOHEP. Five questions measured aspects of parental toothbrushing for their children (frequency, using fluoridated toothpaste, brushing before bed, not drinking or eating after nighttime brushing, adult assistance), three questions measured other oral health behaviors, and 16 questions measured oral health-related knowledge. Analyses of within-person changes between pre- and post-tests and again between post-test and 3-month follow-up consisted of McNemar's test for binary outcomes and sign tests for ordinal outcomes. Overall, 105 caregivers participated in CCOHEP (n = 105 pretest, n = 95 post-test, n = 79 second post-test). At baseline, all parents self-reported doing at least one aspect of toothbrushing correctly, but only 13% reported performing all five aspects according to professional guidelines. At post-test, 44% of parents reported completing all aspects of toothbrushing according to professional guidelines (P < .001). Statistically significant improvements were seen in 4 aspects of toothbrushing (P ≤ .008) between pretest and post-test (all but adult assistance). The second post-test showed 3 of these improvements were maintained, while adult assistance and the other reported behaviors improved (P ≤ .008). Between pretest and post-test, checking child's teeth monthly and frequency of sweet drinks consumption improved (P ≤ .008), while frequency of eating sweet foods did not change. Knowledge was high at baseline (mean 12.8 of 16), but 6 knowledge items improved significantly between pretest and post-test. Improvements were maintained at second post-test. Contra Caries Oral Health Education Program improved low-income Spanish-speaking parents' oral hygiene knowledge and self-reported behaviors for their young children, and change was sustained 3 months after the end of the intervention. Future, more rigorous evaluation of the intervention is recommended. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The tests are to insure that all cells put into the life cycle program are of high quality by the screening of cells found to have electrolyte leakage, internal shorts, low capacity, or inability of any cell to recover its open-circuit voltage above 1.150 volts during the internal short test. Test limits specify those values at which a cell is to be terminated from charge or discharge. Requirements are referenced to normally expected values based on past performance of aerospace nickel-cadmium cells with demonstrated life characteristics. Recommendations for the improvement of the manufacturing processes are presented.

Although critical for improving patient outcomes, palliative care quality indicators are not yet widely used. Better understanding of facilitators and barriers to palliative care quality measurement and improvement might improve their use and program quality. Development of a survey tool to assess palliative care team perspectives on facilitators and barriers to quality measurement and improvement in palliative care programs. We used the adapted Consolidated Framework for Implementation Research to define domains and constructs to select instruments. We assembled a draft survey and assessed content validity through pilot testing and cognitive interviews with experts and frontline practitioners for key items. We analyzed responses using a constant comparative process to assess survey item issues and potential solutions. We developed a final survey using these results. The survey includes five published instruments and two additional item sets. Domains include organizational characteristics, individual and team characteristics, intervention characteristics, and process of implementation. Survey modules include Quality Improvement in Palliative Care, Implementing Quality Improvement in the Palliative Care Program, Teamwork and Communication, Measuring the Quality of Palliative Care, and Palliative Care Quality in Your Program. Key refinements from cognitive interviews included item wording on palliative care team members, programs, and quality issues. This novel, adaptable instrument assesses palliative care team perspectives on barriers and facilitators for quality measurement and improvement in palliative care programs. Next steps include evaluation of the survey's construct validity and how survey results correlate with findings from program quality initiatives.

The undergraduate nursing program at the authors' university began to implement a secure laptop-based testing program in 2009, which allowed students to use their newly purchased laptops to take quizzes and tests securely in classrooms. After nearly 5 years' secure laptop-based testing program implementation, a formative evaluation, using a mixed method that has both descriptive and correlational data elements, was conducted to seek constructive feedback from students to improve the program. Evaluation data show that, overall, students (n = 166) believed the secure laptop-based testing program helps them get hands-on experience of taking examinations on the computer and gets them prepared for their computerized NCLEX-RN. Students, however, had a lot of concerns about laptop glitches and campus wireless network glitches they experienced during testing. At the same time, NCLEX-RN first-time passing rate data were analyzed using the χ2 test, and revealed no significant association between the two testing methods (paper-and-pencil testing and the secure laptop-based testing) and students' first-time NCLEX-RN passing rate. Based on the odds ratio, however, the odds of students passing NCLEX-RN the first time was 1.37 times higher if they were taught with the secure laptop-based testing method than if taught with the traditional paper-and-pencil testing method in nursing school. It was recommended to the institution that better quality of laptops needs to be provided to future students, measures needed to be taken to further stabilize the campus wireless Internet network, and there was a need to reevaluate the Laptop Initiative Program.

To evaluate the impact of a tuberculosis (TB) educational intervention (EI) on change in adolescent student knowledge and participation in a TB prevention program. From 2/2013-5/2015, students from 2 high schools in Houston, TX participated. The 25-min EI discussed TB bacteriology, epidemiology, symptoms, and indications for TB testing/treatment. Students completed pre- and post-quizzes. Immediately after the EI, students were invited to participate in voluntary TB risk-factor screening, testing and treatment. At 6 months, focus groups were conducted. 895 students attended the EI. 827 students (92%) completed the EI quizzes. Knowledge improved by 12% (pre: 70%; post: 82%, p<0.001); 78% shared their TB knowledge. Following the EI, 671/827 (81%) enrolled in a TB prevention program. Focus groups indicated that the EI stimulated student learning about TB and increased their willingness to participate. A brief, one-time, TB EI is an effective method to encourage adolescents to learn about TB and motivate their uptake of TB risk-factor screening, testing and treatment. Similar EIs should accompany TB prevention programs targeting adolescents. The study's procedures could be considered for incorporation into school-based TB prevention programs to improve the identification, testing and treatment of adolescents at risk for TB.

To compare the effectiveness of a core stability program with a task-oriented motor training program in improving motor proficiency in children with developmental coordination disorder (DCD). Randomized controlled pilot trial. Outpatient unit in a hospital. Twenty-two children diagnosed with DCD aged 6-9 years were randomly allocated to the core stability program or the task-oriented motor program. Both groups underwent their respective face-to-face training session once per week for eight consecutive weeks. They were also instructed to carry out home exercises on a daily basis during the intervention period. Short Form of the Bruininks-Oseretsky Test of Motor Proficiency (Second Edition) and Sensory Organization Test at pre- and post-intervention. Intention-to-treat analysis revealed no significant between-group difference in the change of motor proficiency standard score (P=0.717), and composite equilibrium score derived from the Sensory Organization Test (P=0.100). Further analysis showed significant improvement in motor proficiency in both the core stability (mean change (SD)=6.3(5.4); p=0.008) and task-oriented training groups (mean change(SD)=5.1(4.0); P=0.007). The composite equilibrium score was significantly increased in the task-oriented training group (mean change (SD)=6.0(5.5); P=0.009), but not in the core stability group (mean change(SD) =0.0(9.6); P=0.812). In the task-oriented training group, compliance with the home program was positively correlated with change in motor proficiency (ρ=0.680, P=0.030) and composite equilibrium score (ρ=0.638, P=0.047). The core stability exercise program is as effective as task-oriented training in improving motor proficiency among children with DCD. © The Author(s) 2014.

During the past 25 years, the College of American Pathologists' (CAP) Q-Probes program has been available as a subscription program to teach laboratorians how to improve the quality of clinical laboratory services. To determine the accomplishments of the CAP Q-Probes program. We reviewed Q-Probes participant information, study data and conclusions, author information, and program accomplishments. During this time 117 Q-Probes clinical pathology studies were conducted by 54 authors and coauthors, 42,899 laboratories enrolled from 24 countries, 98 peer-reviewed publications occurred and were cited more than 1600 times, and the studies were featured 59 times in CAP Today. The most frequent studies (19) focused on turnaround times for results or products at specific locations (emergency department, operating room, inpatients, outpatients), specific diseases (acute myocardial infarction, urinary tract), availability for specific events such as morning rounds or surgery, a specific result (positive blood cultures), and a method on how to use data for improvement (stat test outliers). Percentile ranking of study participants with better performance provided benchmarks for each study with attributes statistically defined that influenced improved performance. Other programs, such as an ongoing quality improvement program (Q-Tracks), a laboratory competency assessment program, a pathologist certification program, and an ongoing physician practice evaluation program (Evalumetrics), have been developed from Q-Probes studies. The CAP's Q-Probes program has made significant contributions to the medical literature and has developed a worldwide reputation for improving the quality of clinical pathology services worldwide.

2007-01-01

African American adolescents disproportionately perform poorly compared to peers in both behavioral and academic aspects of their educational experience. In this study, African American male students participated in an after-school program involving tutoring, group counseling, and various enrichment activities. All students were assessed regarding their behavioral changes using attendance, discipline referrals, suspensions, and expulsions reports. The Kaufman Brief Intelligence Test (KBIT) and the Kaufman Test of Educational Achievement (KTEA) were used to assess the adolescents' improvement in their skills in reading and mathematics. After the end of the two-year program, initial results showed that the adolescents had increased their daily attendance, decreased discipline referrals, and had no suspensions or expulsions. These results also indicated that although the students entered the program at different skill levels, they were assessed to have the ability to function at their appropriate grade level. Their average improvement in basic skills was at least two grade levels. Implications drawn from the findings include: (a) there is a need to emphasize appropriate assessment prior to beginning a skill improvement program; (b) a need to emphasize the use of individualized learning plans and tutors; and (c) a need to further investigate the role of assessment and intervention in after-school programming in order to close the achievement gap.

Background Cancer can affect many dimensions of a patient’s life, and in turn, it should be targeted using a multimodal approach. We tested the extent to which an interdisciplinary nutrition–rehabilitation program can improve the well-being of patients with advanced cancer. Methods Between January 10, 2007, and September 29, 2010, 188 patients with advanced cancer enrolled in the 10–12-week program. Body weight, physical function, symptom severity, fatigue dimensions, distress level, coping ability, and overall quality of life were assessed at the start and end of the program. Results Of the enrolled patients, 70% completed the program. Patients experienced strong improvements in the physical and activity dimensions of fatigue (effect sizes: 0.8–1.1). They also experienced moderate reductions in the severity of weakness, depression, nervousness, shortness of breath, and distress (effect sizes: 0.5–0.7), and moderate improvements in Six Minute Walk Test distance, maximal gait speed, coping ability, and quality of life (effect sizes: 0.5–0.7) Furthermore, 77% of patients either maintained or increased their body weight. Conclusions Interdisciplinary nutrition–rehabilitation can be advantageous for patients with advanced cancer and should be considered an integrated part of standard palliative care. PMID:24311946

There are 341 000 patients in the United States who are dependent on routine dialysis for survival. Recent large-scale disasters have emphasized the importance of disaster preparedness, including supporting dialysis units, for people with chronic disease. Contingency plans for staffing are important for providing continuity of care for a technically challenging procedure such as dialysis. PReparing Emergency Personnel in Dialysis (PREP-D) is a just-in-time training program designed to train individuals having minimum familiarity with the basic steps of dialysis to support routine dialysis staff during a disaster. A 5-module educational program was developed through a collaborative, multidisciplinary effort. A pilot study testing the program was performed using 20 nontechnician dialysis facility employees and 20 clinical-year medical students as subjects. When comparing pretest and posttest scores, the entire study population showed a mean improvement of 28.9%, with dialysis facility employees and medical students showing improvements of 21.8% and 36.4%, respectively (P < .05 for all comparisons). PREP-D participants were able to demonstrate improved tests scores when taught in a just-in-time training format. The knowledge gained by using the PREP-D program during a staffing shortage may allow for continuity of care for critical services such as dialysis during a disaster.

This paper reports on the questions: should Congress provide more funds for the Air Force's current plan---the CORE program---to upgrade the B-1B defense avionics system In GAO's view, more testing of the system is not necessary to determine whether to implement the CORE program. Flight testing has shown that the CORE modifications would provide similar operational capabilities to, and offer some survivability improvements over, the existing defense avionics system. The only reason for additional testing would be to prove that some problems with the maintenance diagnostic system has been resolved. Initial testing revealed that while some improvements were achieved, usermore » requirements were not met for such things as low false alarm rates and cannot duplicate rates. Even if the maintenance diagnostic capabilities were fully demonstrated, however, the CORE system should not be implemented until it is known whether the defense avionics system design can support the B-1B's new role as a conventional bomber.« less

Falls are a major source of injury in the elderly and their incomplete management is a cause for concern by health systems. The present study looks at the current state of managing fall victims in Iran and offers suggestions for improvement. This was a clinical care audit comparing the state of current care with an institutionally approved optimum. Patients aged 60 years and over presenting with a fall were evaluated and deficiencies in their care were recorded and categorized. These were presented to an expert panel, where the Delphi method was used to come up with a list of actions to address the deficiencies. Furthermore an educational program was implemented based on these suggestions. Chi-squared and t-test were used to evaluate the efficacy of this program in improving treatment. Linear regression analysis was used to find factors affecting care. Overall 431 cases were reviewed. The most common errors during clinical examination were: not performing Romberg test (92.75%) and lack of physiotherapy consultation (82.75%). The educational program had a modest effect on improving the clinical audit processes (β = 3.79; P < 0.001) and medical interventions (β = 2.004; P = 0.002); however, performing the correct diagnostic tests was worse after the program (β = -1.21; P = 0.008). There is a wide gap between the care services delivered in the management of falls and international standards. Therefore, measures should be adopted to close this gap. Education may have a modest positive effect in this regard. Copyright © 2015 Elsevier Ltd. All rights reserved.

In 2001, the National Heart, Lung, and Blood Institute partnered with the National Council of La Raza to conduct a pilot test of its community-based outreach program Salud Para Su Corazón (Health for Your Heart), which aims to reduce the burden of morbidity and mortality associated with cardiovascular disease among Latinos. The effectiveness of promotores de salud (community health workers) in improving heart-healthy behaviors among Latino families participating in the pilot program at seven sites was evaluated. Data on the characteristics of the promotores in the Salud Para Su Corazón program were compiled. Promotores collected data on family risk factors, health habits, referrals and screenings, information sharing, and program satisfaction from 223 participating Latino families (320 individual family members) through questionnaires. Paired t tests and chi-square tests were used to measure pretest-posttest differences among program participants. Results demonstrated the effectiveness of the promotora model in improving heart-healthy behaviors, promoting community referrals and screenings, enhancing information sharing beyond families, and satisfying participants' expectations of the program. The main outcome of interest was the change in heart-healthy behaviors among families. The community outreach model worked well in the seven pilot programs because of the successes of the promotores and the support of the community-based organizations. Successes stemmed in part from the train-the-trainer approach. Promotoria, as implemented in this program, has the potential to be integrated with a medical model of patient care for primary, secondary, and tertiary prevention.

The purpose of the present study was to determine the value of virtual reality (VR) training for a multimodality training program of basic laparoscopic surgery. Participants in a two-day multimodality training for laparoscopic surgery used box trainers, live animal training, and cadaveric training on the pulsating organ perfusion (POP) trainer in a structured and standardized training program. The participants were divided into two groups. The VR group (n = 13) also practiced with VR training during the program, whereas the control group (n = 14) did not use VR training. The training modalities were assessed using questionnaires with a five-point Likert scale after the program. Concerning VR training, members of the control group assessed their expectations, whereas the VR group assessed the actual experience of using it. Skills performance was evaluated with five standardized test tasks in a live porcine model before (pre-test) and after (post-test) the training program. Laparoscopic skills were measured by task completion time and a general performance score for each task. Baseline tests were compared with laparoscopic experience of all participants for construct validity of the skills test. The expected benefit from VR training of the control group was higher than the experienced benefit of the VR group. Box and POP training received better ratings from the VR group than from the control group for some purposes. Both groups improved their skill parameters significantly from pre-training to post-training tests [score +17 % (P < 0.01), time -29 % (P < 0.01)]. No significant difference was found between the two groups for laparoscopic skills improvement except for the score in the instrument coordination task. Construct validity of the skills test was significant for both time and score. At its current level of performance, VR training does not meet expectations. No additional benefit was observed from VR training in our multimodality training program.

2009-04-01

In response to the increased incidence of child overweight, a school-based program, It's All About Kids, was designed by the Tulsa Health Department, Tulsa Public Schools, and community partners to improve food choices and increase physical activity of students in first through fifth grade. The nutrition component consisted of six weekly 30-minute experiential, age-appropriate classroom lessons, including healthful-eating food games, taste-testing foods, whole-grain bread baking, information on portion sizes, and food demonstrations. Documenting and evaluating school-based intervention programs is critical for setting evidence-based health policy, justifying funding, and achieving broader implementation of successful interventions. To evaluate the effectiveness of the It's All About Kids nutrition component in fourth-grade children, we conducted a controlled trial from 20 fourth-grade classes in five intervention and five comparison Title I public schools. Evaluation included 140 fourth-grade students, including 69 in the comparison group and 71 in the intervention group. Outcomes were measured by pre-, post-, and follow-up tests using a modified version of the Pathways Knowledge, Attitudes, and Behaviors questionnaire and the Child and Adolescent Trial of Cardiovascular Health (CATCH) Food Checklist. Data were analyzed using repeated measures analysis of variance over time controlling for sex, paired samples t tests, and independent samples t tests. Intervention students had significant improvements in knowledge of which food had more fat (P<0.043). Intervention students' behavioral intent scale scores for food choice intentions improved significantly (P<0.014). Self-reported consumption of saturated fat and sodium improved considerably in both intervention and comparison students. We conclude that results support a broader program implementation. More reinforcement over time may be needed to sustain the level of improvement.

BACKGROUND Virtual reality reflection therapy (VRRT) is a technically enhanced version of the mirror therapy concept. The aim of this study was to investigate whether VRRT could improve the postural balance and gait ability of patients with chronic stroke. MATERIAL AND METHODS Twenty-five patients with chronic stroke were randomly allocated into the VRRT group (n=13) and the control group (n=12). The participants in both groups performed a conventional rehabilitation program for 30 minutes. The VRRT group also performed a VRRT program for 30 minutes, five times a week for 4 weeks. The control group performed conventional rehabilitation program and a placebo VRRT program. Outcome measures included Berg Balance Scale (BBS), the Functional Reaching Test (FRT), and the Timed Up and Go (TUG) test (for dynamic balance ability), postural sway (for static balance ability), and 10 meter walking velocity (10 mWV) for gait ability. RESULTS There were statistically significant improvements in the VRRT group compared with the control group for BBS, FRT, TUG, postural sway (mediolateral sway distance with eyes open and eyes closed, anteroposterior and total sway distance with eyes open but not with eyes closed), and 10 mWV (p<0.05). CONCLUSIONS Applying VRRT (even as a home treatment) along with a conventional rehabilitation program for patients with chronic stroke might be even more beneficial than conventional rehabilitation program alone in improving affected lower limb function. Future studies should investigate the effectiveness of VRRT with optimal patient selection, and duration and intensity of training.

The purpose of this study was to evaluate the efficacy of a multidisciplinary treatment program in patients severely affected by fibromyalgia. Thirty-four fibromyalgia patients were randomly divided into two groups. The control group: 17 women who continued their medical treatment and participated in four educational sessions and the experimental group that included 17 patients who besides the former medical treatment also underwent a weekly 1-h session program for 8 weeks including massage therapy, ischemic pressure on the 18 tender points, aerobic exercise and thermal therapy. At the beginning of the program, there were no significant differences between the two groups in any of the parameters. At the end of treatment, there was a significant improvement in the experimental group in the following items: vitality, social functioning, grip strength and the 6-min walk test. At 1 month after the end of treatment, the experimental group showed significant differences in overall health perception, social functioning, grip strength and the 6-min walk test. At that time, considering the threshold for clinical efficacy set at an improvement of 30% or above for the analyzed variables, 25% of the patients met the requirement for improvement of the following: number of symptoms: Visual Analogic Scale for fatigue, Fibromyalgia Impact Questionnaire and Beck Anxiety Inventory. In conclusion, patients with severe manifestations of fibromyalgia can obtain improvement with a short-term, low-cost and simple-delivery multidisciplinary program. However, additional studies including higher numbers of patients are needed to confirm the beneficial effect of this treatment program.

Among people who are hospitalised for community-acquired pneumonia, does an inpatient exercise-based rehabilitation program improve functional outcomes, symptoms, quality of life and length of hospital stay more than a respiratory physiotherapy regimen? Randomised trial with concealed allocation, intention-to-treat analysis and blinding of some outcomes. Forty-nine adults hospitalised for community-acquired pneumonia. The experimental group (n=32) underwent a physical training program that included warm-up, stretching, peripheral muscle strength training and walking at a controlled speed for 15 minutes. The control group (n=17) underwent a respiratory physiotherapy regimen that included percussion, vibrocompression, respiratory exercises and free walking. The intervention regimens lasted 8 days. The primary outcome was the Glittre Activities of Daily Living test, which assesses the time taken to complete a series of functional tasks (eg, rising from a chair, walking, stairs, lifting and bending). Secondary outcomes were distance walked in the incremental shuttle walk test, peripheral muscle strength, quality of life, dyspnoea, lung function, C-reactive protein and length of hospital stay. Measures were taken 1 day before and 1 day after the intervention period. There was greater improvement in the experimental group than in the control group on the Glittre Activities of Daily Living test (mean between-group difference 39 seconds, 95% CI 20 to 59) and the incremental shuttle walk test (mean between-group difference 130 m, 95% CI 77 to 182). There were also significantly greater improvements in quality of life, dyspnoea and peripheral muscle strength in the experimental group than in the control group. There were no between-group differences in lung function, C-reactive protein or length of hospital stay. The improvement in functional outcomes after an inpatient rehabilitation program was greater than the improvement after standard respiratory physiotherapy. The exercise training program led to greater benefits in functional capacity, peripheral muscle strength, dyspnoea and quality of life. ClinicalTrials.gov, NCT02103400.

Dutch practice nurses sub-optimally adhere to evidence-based smoking cessation guidelines. Web-based computer-tailoring could be effective in improving their guideline adherence. Therefore, this paper aims to describe the development of a web-based computer-tailored program and the design of a randomized controlled trial testing its (cost-)effectiveness. Theoretically grounded in the I-Change Model and Self-Determination Theory, and based on the results of a qualitative needs assessment among practice nurses, a web-based computer-tailored program was developed including three modules with tailored advice, an online forum, modules with up-to-date information about smoking cessation, Frequently Asked Questions (FAQs) and project information, and a counseling checklist. The program's effects are assessed by comparing an intervention group (access to all modules) with a control group (access to FAQs, project information and counseling checklist only). Smoking cessation guideline adherence and behavioral predictors (i.e. intention, knowledge, attitude, self-efficacy, social influence, action and coping planning) are measured at baseline and at 6- and 12-month follow-up. Additionally, the program's indirect effects on smokers' quit rates and the number of quit attempts are assessed after 6 and 12months. This paper describes the development of a web-based computer-tailored adherence support program for practice nurses and the study design of a randomized controlled trial testing its (cost-)effectiveness. This program potentially contributes to improving the quality of smoking cessation care in Dutch general practices. If proven effective, the program could be adapted for use by other healthcare professionals, increasing the public health benefits of improved smoking cessation counseling for smokers.

Maintaining employment is difficult for patients with schizophrenia because of deterioration of psychosocial and cognitive functions. Such patients usually require vocational rehabilitation training, which is both demanding and costly. In this study, we developed a virtual reality-based vocational rehabilitation training program (VR-VRTP) for such patients and evaluated its feasibility as an alternative to traditional rehabilitation programs. We developed the VR-VRTP to include various situations commonly encountered in two types of occupations: convenience store employee and supermarket clerk. We developed practical situations, as well as a system for providing feedback, to ensure patients would not lose interest during training. Nine participants each performed the VR-VRTP repeatedly per week for a total of 8 weeks. At baseline and after training, all participants were evaluated using the following clinical and neuropsychological tests: Manchester Scale, Clinical Global Impression, Personal and Social Performance Scale (PSP), Hamilton Depression Rating Scale, Zung Depression Rating Scale, Beck Anxiety Inventory, Wisconsin Card Sorting Test, Stroop Test, Rey-Osterrieth Complex Figure Test (RCFT), and Auditory Verbal Learning Test (AVLT). After training, patient scores improved on the PSP, general symptoms on the Manchester Scale, AVLT, and delayed recall on the RCFT. The Manchester positive symptom score showed a trend of improvement. No significant changes were observed for other measures. The VR-VRTP may improve general psychosocial function and memory, potentially influencing real-world vocational performance. These findings provide preliminary evidence regarding the utility of the VR-VRTP in patients with schizophrenia.

Competency Assessment of Microbiology Medical Laboratory Technologists in Ontario, Canada

PubMed Central

Fleming, Christine Ann

2014-01-01

Accreditation in Ontario, Canada, requires that licensed clinical laboratories participate in external quality assessment (also known as proficiency testing) and perform competency evaluation of their staff. To assess the extent of ongoing competency assessment practices, the Quality Management Program—Laboratory Services (QMP-LS) Microbiology Committee surveyed all 112 licensed Ontario microbiology laboratories. The questionnaire consisted of a total of 21 questions that included yes/no, multiple-choice, and short-answer formats. Participants were asked to provide information about existing programs, the frequency of testing, what areas are evaluated, and how results are communicated to the staff. Of the 111 responding laboratories, 6 indicated they did not have a formal evaluation program since they perform only limited bacteriology testing. Of the remaining 105 respondents, 87% perform evaluations at least annually or every 2 years, and 61% include any test or task performed, whereas 16% and 10% focus only on problem areas and high-volume complex tasks, respectively. The most common methods of evaluation were review of external quality assessment (EQA) challenges, direct observation, and worksheet review. With the exception of one participant, all communicate results to staff, and most take remedial action to correct the deficiencies. Although most accredited laboratories have a program to assess the ongoing competency of their staff, the methods used are not standardized or consistently applied, indicating that there is room for improvement. The survey successfully highlighted potential areas for improvement and allowed the QMP-LS Microbiology Committee to provide guidance to Ontario laboratories for establishing or improving existing microbiology-specific competency assessment programs.

To compare the effect of a custom-designed yoga program with 2 other balance training programs. Randomized controlled trial. Research laboratory. A group of older adults (N=39; mean age, 74.15 ± 6.99 y) with a history of falling. Three different exercise interventions (Tai Chi, standard balance training, yoga) were given for 12 weeks. Balance performance was examined during pre- and posttest using field tests, including the 8-foot up-and-go test, 1-leg stance, functional reach, and usual and maximal walking speed. The static and dynamic balances were also assessed by postural sway and dynamic posturography, respectively. Training produced significant improvements in all field tests (P<.005), but group difference and time × group interaction were not detected. For postural sway, significant decreases in the area of the center of pressure with eyes open (P=.001) and eyes closed (P=.002) were detected after training. For eyes open, maximum medial-lateral velocity significantly decreased for the sample (P=.013). For eyes closed, medial-lateral displacement decreased for Tai Chi (P<.01). For dynamic posturography, significant improvements in overall score (P=.001), time on the test (P=.006), and 2 linear measures in lateral (P=.001) and anterior-posterior (P<.001) directions were seen for the sample. Yoga was as effective as Tai Chi and standard balance training for improving postural stability and may offer an alternative to more traditional programs.

Successful community groups have the capacity to mobilize community assets to address needs. Capacity-building education is integral to building competent communities. A community-university team developed and pilot tested an education program for community advocates from disadvantaged neighborhoods with high chronic disease burden. The Community Advocacy and Leadership Program (CALP) included eight monthly workshops, a mini-grant opportunity, and technical assistance. A nominal group with community health practitioners, focus group with community advocates, and a literature search comprised a triangulated educational needs assessment. A participating pretest with 35 community health practitioners guided curriculum refinement. Seven representatives from three community groups in a medically underserved South Carolina county participated in pilot implementation and evaluation. Qualitative and quantitative data informed the process and impact evaluation. The mean knowledge score at 1 month after the program was 77% (range, 52%-96%). The mean score on post-program self-assessment of skills improvement was 3.8 out of a possible 4.0 (range, 3.6-4.0). Two groups submitted successful community mini-grant applications for playground improvements, and the third group successfully advocated for public funding of neighborhood park improvements. Participants reported favorable impressions and both personal and community benefits from participation. A community-university partnership successfully conducted a local educational needs assessment and developed and pilot tested a capacity development program within a CBPR partnership. Successes, challenges, and lessons learned will guide program refinement, replication, and dissemination.

Primary health workers play a critical role in providing health education to people with mental disorders. In China community health workers working with people with mental health problems lack experience and training in this area. Additionally, coordination between hospital and community staff is not well established. The aim of this study was to provide an interdisciplinary community mental health training program and to evaluate the effect of the training on staff knowledge about mental health and confidence in their roles. A three-day community mental health training program was offered specifically for interdisciplinary mental health professionals. Using a one-group pre-test post-test design, participants completed a self-assessment of mental health concepts and program evaluation which included asking participants to rate their satisfaction using a five-point Likert scale and to respond to open-ended questions. Forty-eight participants including health professionals from colleges, hospital and community health centers were recruited. Only 8.7% of participants had ever received community mental health training. Post-test evaluation demonstrated improvements in knowledge, and most participants were very satisfied with the program. The findings indicate that this brief interdisciplinary training program had a positive effect in improving knowledge about community mental health concepts and confidence in dealing with people with mental health disorders for multidisciplinary staff working in primary health care areas.

Sensory motor training programs are used in the rehabilitation and prevention of injuries among soccer players. Inconsistencies are found in the literature regarding the duration of the protocols and the exercises and equipment used. To evaluate the benefits of a five-week sensory motor training program on the functional performance and postural control of young soccer players. The study sample comprised 22 young male soccer players who were evaluated using: the Figure-of-Eight Test (F8), Side Hop Test (SHT), Star Excursion Balance Test (SEBT), and a force platform. The players were randomly divided into a control group (N = 10), who continued their soccer practice sessions and an intervention group (N = 12), who continued their soccer practice sessions and were also enrolled in a supervised five-week sensory motor training program. After the five-week training program, the intervention group obtained significant results in the F8, SHT and SEBT, as well as in the following parameters: area of pressure of sway center (COP), mean velocity and mean frequency of COP. The five-week sensory motor training program, carried out with easily available and low cost equipment, was effective at improving functional performance and postural control in young soccer players.

Kumpfer, Karol L; Smith, Paula; Summerhays, Julia Franklin

2008-07-01

Substance misuse in adolescent girls has increased dramatically since 1992. This article reviews trends in use rates and etiological theories tested by gender that suggest that family protective factors have more influence on girls. Next, a literature review reveals that few prevention programs have published their outcomes by gender or developed gender-specific programs. Nationwide community coalition results found positive effects on boys but increased drug use in young girls. The most effective programs are family focused targeting family bonding, supervision, and communication. Recent gender-specific prevention programs with positive results address stress, depression, social assertiveness, and body image. The authors recommend additional research testing programs by gender and also gender-specific versus generic versions of evidence-based programs to determine how to improve prevention program effectiveness for girls.

Industry/NASA Reusable Launch Vehicle (RLV) Technology Program efforts are underway to design, test, and develop technologies and concepts for viable commercial launch systems that also satisfy national needs at acceptable recurring costs. Significant progress has been made in understanding the technical challenges of fully reusable launch systems and the accompanying management and operational approaches for achieving a low-cost program. This paper reviews the current status of the Reusable Launch Vehicle Technology Program including the DC-XA, X-33 and X-34 flight systems and associated technology programs. It addresses the specific technologies being tested that address the technical and operability challenges of reusable launch systems including reusable cryogenic propellant tanks, composite structures, thermal protection systems, improved propulsion, and subsystem operability enhancements. The recently concluded DC-XA test program demonstrated some of these technologies in ground and flight tests. Contracts were awarded recently for both the X-33 and X-34 flight demonstrator systems. The Orbital Sciences Corporation X-34 flight test vehicle will demonstrate an air-launched reusable vehicle capable of flight to speeds of Mach 8. The Lockheed-Martin X-33 flight test vehicle will expand the test envelope for critical technologies to flight speeds of Mach 15. A propulsion program to test the X-33 linear aerospike rocket engine using a NASA SR-71 high speed aircraft as a test bed is also discussed. The paper also describes the management and operational approaches that address the challenge of new cost-effective, reusable launch vehicle systems.

Purpose The aim of this study was to investigate the effect of a combined program including sprint repetitions and drop jump training in the same session on male handball players. Methods Twenty-two male handball players aged more than 20 years were assigned into 2 groups: experimental group (n=11) and control group (n=11). Selection was based on variables “axis” and “lines”, goalkeepers were not included. The experimental group was subjected to 2 testing periods (test and retest) separated by 12 weeks of an additional combined plyometric and running speed training program. The control group performed the usual handball training. The testing period comprised, at the first day, a medical checking, anthropometric measurements and an incremental exercise test called yo-yo intermittent recovery test. 2 days later, participants performed the Repeated Sprint Ability test (RSA), and performed the Jumping Performance using 3 different events: Squat jump (SJ), Countermovement jump without (CMJ) and with arms (CMJA), and Drop jump (DJ). At the end of the training period, participants performed again the repeated sprint ability test, and the jumping performance. Results The conventional combined program improved the explosive force ability of handball players in CMJ (P=0.01), CMJA (P=0.01) and DJR (P=0.03). The change was 2.78, 2.42 and 2.62% respectively. No significant changes were noted in performances of the experimental group at the squat jump test and the drop jump with the left leg test. The training intervention also improved the running speed ability of the experimental group (P=0.003). No statistical differences were observed between lines or axes. Conclusion Additional combined training program between sprint repetition and vertical jump in the same training session positively influence the jumping ability and the sprint ability of handball players.

Critical reflection is effective in improving students' communication abilities and confidence. The aim of this study was to evaluate the effectiveness of a work-based critical reflection program to enhance novice nurses' clinical critical-thinking abilities, communication competency, and job performance. The present study used a quasi-experimental design. From October 2014 to August 2015, we collected data from 44 novice nurses working in an advanced general hospital in S city in Korea. Nurses in the experimental group participated in a critical reflection program for six months. Outcome variables were clinical critical-thinking skills, communication abilities, and job performance. A non-parametric Mann-Whitney U-test and a Wilcoxon rank sum test were selected to evaluate differences in mean ranks and to assess the null hypothesis that the medians were equal across the groups. The results showed that the clinical critical-thinking skills of those in the experimental group improved significantly (p = 0.003). The differences in mean ranks of communication ability between two groups was significantly statistically different (p = 0.028). Job performance improved significantly in both the experimental group and the control group, so there was no statistical difference (p = 0.294). We therefore suggest that a critical reflection program be considered an essential tool for improving critical thinking and communication abilities among novice nurses who need to adapt to the clinical environment as quickly as possible. Further, we suggest conducting research into critical reflection programs among larger and more diverse samples.

The purpose of this project was to evaluate integrated packages of advanced measures in individual test homes to assess their performance with respect to Building America program goals, specifically compliance with the DOE Challenge Home Program. BSC consulted on the construction of five test houses by three cold climate production builders in three U.S. cities and worked with the builders to develop a design package tailored to the cost-related impacts for each builder. Also, BSC provided support through performance testing of the five test homes. Overall, the builders have concluded that the energy related upgrades (either through the prescriptive ormore » performance path) represent reasonable upgrades. The builders commented that while not every improvement in specification was cost effective (as in a reasonable payback period), many were improvements that could improve the marketability of the homes and serve to attract more energy efficiency discerning prospective homeowners. However, the builders did express reservations on the associated checklists and added certifications. An increase in administrative time was observed with all builders. The checklists and certifications also inherently increase cost due to: adding services to the scope of work for various trades, such as HERS Rater, HVAC contractor; and increased material costs related to the checklists, especially the EPA Indoor airPLUS and EPA WaterSense® Efficient Hot Water Distribution requirement.« less

The purpose of this study was to investigate the training effects of Virtual Reality (VR) intervention program on reaction time in children with cerebral palsy. Thirty boys ranging from 7 to 12 years (mean = 11.20; SD = .76) were selected by available sampling method and randomly divided into the experimental and control groups. Simple Reaction Time (SRT) and Discriminative Reaction Time (DRT) were measured at baseline and 1 day after completion of VR intervention. Multivariate analysis of variance (MANOVA) and paired sample t-test were performed to analyze the results. MANOVA test revealed significant effects for group in posttest phase, with lower reaction time in both measures for the experimental group. Based on paired sample t-test results, both RT measures significantly improved in experimental group following the VR intervention program. This paper proposes VR as a promising tool into the rehabilitation process for improving reaction time in children with cerebral palsy.

Depression is prevalent among individuals with diabetes and associated with suboptimal self-management. Little is known about the feasibility and potential impact of tele-behavioral therapy to improve depressive symptoms and self-management among diabetes patients. This was a retrospective observational study of consecutive graduates enrolled in a national 8-week diabetes behavioral telehealth program between August 1, 2014, and January 31, 2015 (N = 466; mean age 56.8 ± 5.0 years; 56% female). Participant characteristics (demographics, comorbidities) were obtained by standardized questionnaire. Depression, anxiety, and stress symptoms (DASS; validated Depression Anxiety and Stress Scale 21 survey), and glucose self-testing frequency and values (point-of-care monitor) were measured at program start and completion. Changes in DASS severity and glucose self-testing frequency were assessed by chi-square tests. Changes in DASS and blood glucose levels were evaluated by paired t-tests. At baseline, approximately one in three participants had elevated depression (32%), anxiety (33%), or stress (31%) scores. Significant reductions in average DASS, depression (-8.8), anxiety (-6.9), and stress (-9.9), scores were observed at graduation among those with elevated baseline scores (p < 0.0001); most (≥80%) improved to less severe depression, anxiety, or stress categories. Improved glucose self-testing frequency (69% vs. 60% tested ≥once per week; p = 0.0005) and significant reductions in mean morning glucose levels (-12.3 mg/dL; p = 0.0002) were observed from baseline to graduation. Participants with normal versus non-normal depression scores were more likely to have lower (

A nontraditional form of exercise recently applied for patients with Parkinson disease (PD) is boxing training. The primary purpose of this case series is to describe the effects of disease severity and duration of boxing training (short term and long term) on changes in balance, mobility, and quality of life for patients with mild or moderate to severe PD. The feasibility and safety of the boxing training program also were assessed. Six patients with idiopathic PD attended 24 to 36 boxing training sessions for 12 weeks, with the option of continuing the training for an additional 24 weeks (a seventh patient attended sessions for only 4 weeks). The 90-minute sessions included boxing drills and traditional stretching, strengthening, and endurance exercises. Outcomes were tested at the baseline and after 12, 24, and 36 weeks of boxing sessions (12-, 24-, and 36-week tests). The outcome measures were the Functional Reach Test, Berg Balance Scale, Activities-specific Balance Confidence Scale, Timed "Up & Go" Test, Six-Minute Walk Test, gait speed, cadence, stride length, step width, activities of daily living and motor examination subscales of the Unified Parkinson Disease Rating Scale, and Parkinson Disease Quality of Life Scale. Six patients completed all phases of the case series, showed improvements on at least 5 of the 12 outcome measures over the baseline at the 12-week test, and showed continued improvements at the 24- and 36-week tests. Patients with mild PD typically showed improvements earlier than those with moderate to severe PD. Despite the progressive nature of PD, the patients in this case series showed short-term and long-term improvements in balance, gait, activities of daily living, and quality of life after the boxing training program. A longer duration of training was necessary for patients with moderate to severe PD to show maximal training outcomes. The boxing training program was feasible and safe for these patients with PD.

Operators continue to look for ways to improve hard rock drilling performance through emerging technologies. A consortium of Department of Energy, operator and industry participants put together an effort to test and optimize mud driven fluid hammers as one emerging technology that has shown promise to increase penetration rates in hard rock. The thrust of this program has been to test and record the performance of fluid hammers in full scale test conditions including, hard formations at simulated depth, high density/high solids drilling muds, and realistic fluid power levels. This paper details the testing and results of testing two 7more » 3/4 inch diameter mud hammers with 8 1/2 inch hammer bits. A Novatek MHN5 and an SDS Digger FH185 mud hammer were tested with several bit types, with performance being compared to a conventional (IADC Code 537) tricone bit. These tools functionally operated in all of the simulated downhole environments. The performance was in the range of the baseline ticone or better at lower borehole pressures, but at higher borehole pressures the performance was in the lower range or below that of the baseline tricone bit. A new drilling mode was observed, while operating the MHN5 mud hammer. This mode was noticed as the weight on bit (WOB) was in transition from low to high applied load. During this new ''transition drilling mode'', performance was substantially improved and in some cases outperformed the tricone bit. Improvements were noted for the SDS tool while drilling with a more aggressive bit design. Future work includes the optimization of these or the next generation tools for operating in higher density and higher borehole pressure conditions and improving bit design and technology based on the knowledge gained from this test program.« less

Nonlinear Boltzmann equation for the homogeneous isotropic case: Minimal deterministic Matlab program

NASA Astrophysics Data System (ADS)

Asinari, Pietro

2010-10-01

The homogeneous isotropic Boltzmann equation (HIBE) is a fundamental dynamic model for many applications in thermodynamics, econophysics and sociodynamics. Despite recent hardware improvements, the solution of the Boltzmann equation remains extremely challenging from the computational point of view, in particular by deterministic methods (free of stochastic noise). This work aims to improve a deterministic direct method recently proposed [V.V. Aristov, Kluwer Academic Publishers, 2001] for solving the HIBE with a generic collisional kernel and, in particular, for taking care of the late dynamics of the relaxation towards the equilibrium. Essentially (a) the original problem is reformulated in terms of particle kinetic energy (exact particle number and energy conservation during microscopic collisions) and (b) the computation of the relaxation rates is improved by the DVM-like correction, where DVM stands for Discrete Velocity Model (ensuring that the macroscopic conservation laws are exactly satisfied). Both these corrections make possible to derive very accurate reference solutions for this test case. Moreover this work aims to distribute an open-source program (called HOMISBOLTZ), which can be redistributed and/or modified for dealing with different applications, under the terms of the GNU General Public License. The program has been purposely designed in order to be minimal, not only with regards to the reduced number of lines (less than 1000), but also with regards to the coding style (as simple as possible).

However, in principle, any recent version of Matlab or Octave should work Computer: All supporting Matlab or Octave Operating system: All supporting Matlab or Octave RAM: 300 MBytes Classification: 23 Nature of problem: The problem consists in integrating the homogeneous Boltzmann equation for a generic collisional kernel in case of isotropic symmetry, by a deterministic direct method. Difficulties arise from the multi-dimensionality of the collisional operator and from satisfying the conservation of particle number and energy (momentum is trivial for this test case) as accurately as possible, in order to preserve the late dynamics. Solution method: The solution is based on the method proposed by Aristov (2001) [1], but with two substantial improvements: (a) the original problem is reformulated in terms of particle kinetic energy (this allows one to ensure exact particle number and energy conservation during microscopic collisions) and (b) a DVM-like correction (where DVM stands for Discrete Velocity Model) is adopted for improving the relaxation rates (this allows one to satisfy exactly the conservation laws at macroscopic level, which is particularly important for describing the late dynamics in the relaxation towards the equilibrium). Both these corrections make possible to derive very accurate reference solutions for this test case. Restrictions: The nonlinear Boltzmann equation is extremely challenging from the computational point of view, in particular for deterministic methods, despite the increased computational power of recent hardware. In this work, only the homogeneous isotropic case is considered, for making possible the development of a minimal program (by a simple scripting language) and allowing the user to check the advantages of the proposed improvements beyond Aristov's (2001) method [1]. The initial conditions are supposed parameterized according to a fixed analytical expression, but this can be easily modified. Running time: From minutes to hours (depending on the adopted discretization of the kinetic energy space). For example, on a 64 bit workstation with Intel CoreTM i7-820Q Quad Core CPU at 1.73 GHz and 8 MBytes of RAM, the provided test run (with the corresponding binary data file storing the pre-computed relaxation rates) requires 154 seconds.

The aim of this study was to identify the effects of a newly developed instructional coaching program regarding Attention Deficit Hyperactivity Disorder (ADHD) for teachers. Seventy teachers participated in this study involving a nonequivalent control group and a pretest-posttest design. The instructional coaching program consisted of eight 60-minute sessions. The program was developed through a theoretical development program involving six steps. To evaluate the effects of the program, data were collected through self-report questionnaires including the Knowledge Scale of Attention Deficit Disorder, Attitude Scale of Primary School Teachers Experiencing Students with ADHD, Practice Scale of Educational Intervention Activity, and the Korean ADHD Rating Scale. Data were analyzed with an independent t test, a chi-square test, and an ANCOVA using SPSS WIN version 20. The intervention program consisted of 3 sectors, 8 subjects, and 24 content items. The experimental group showed a significant improvement in attitudes toward ADHD (F=22.83, p<.001). In addition, teacher's knowledge regarding ADHD (F=7.16, p=.010) and the implementation of instructional interventions (F=4.29, p=.043) improved. Further, teachers reported a reduction in children's ADHD-related behavior (F=4.34, p=.041). Results showed that the coaching program made a positive contribution to teaching skills and understanding of school-age children with ADHD. The instructional coaching program was well structured and significantly improved not only teachers'attitudes, knowledge, and teaching skills but also the behavior of children with ADHD in class. Therefore, the program is recommended as a means of facilitating teaching and managing children with ADHD in class. © 2017 Korean Society of Nursing Science

Experiencing the death of a parent during childhood is associated with a variety of difficulties, including lower academic achievement, that have implications for functioning in childhood and adulthood. This study examines effects of the Family Bereavement Program (FBP), a preventive intervention for parentally-bereaved youth and their caregivers, on grade point averages (GPA), educational expectations and job aspirations of youths 6 years after the intervention. A total of 244 bereaved youths ages 8-16 and their caregivers were randomized to either the FBP or a comparison group that received books about bereavement. Assessments occurred at pretest, post-test, and 11-month and 6-year follow-ups. Direct program effects on educational outcomes and job aspirations 6 years later were non-significant, although the program improved educational expectations for children with fewer behavior problems at program entry, and GPA for younger children. Mediational pathways for program effects on educational outcomes were also tested. Program-induced improvements in effective parenting at 11-month follow-up were associated with higher GPAs at 6-year follow-up for youth who were younger or for whom more time had passed since the loss. Program-induced improvements in parenting and teacher-rated youth mental health problems at the 6-year follow-up mediated program effects on youths’ educational expectations for those with fewer behavior problems at program entry. The implications of these findings for understanding processes related to academic and educational outcomes following the death of a parent and for prevention efforts to help bereaved and other high-risk children succeed in school are discussed.

Epidemiological data demonstrate the need for lower-extremity injury-prevention training. Neuromuscular-control (NMC) programs are immediately effective at minimizing lower-extremity injury risk and improving sport-related performance measures. Research investigating lasting effects after an injury-prevention program is limited. To determine whether dynamic balance, landing mechanics, and hamstring and quadriceps strength could be improved after a 6-wk NMC intervention and maintained for a season. Prospective case series. Controlled laboratory. 11 Division I women's basketball players (age 19.40 ± 1.35 y, height 178.05 ± 7.52 cm, mass 72.86 ± 10.70 kg). Subjects underwent testing 3 times, completing the Star Excursion Balance Test (SEBT), Landing Error Scoring System (LESS), and isometric strength testing for the hamstrings and quadriceps muscles. Pretest and posttest 1 occurred immediately before and after the intervention, respectively, and posttest 2 at the end of the competitive season, 9 mo after posttest 1. Subjects participated in eighteen 30-min plyometric and NMC-training sessions over a 6-wk period. The normalized SEBT composite score, normalized peak isometric hamstrings:quadriceps (H:Q) ratio, and the LESS total score. The mean composite reach significantly improved over time (F2,10 = 6.96, P = .005) where both posttest scores were significantly higher than pretest (70.41% ± 4.08%) (posttest 1 73.48% ± 4.19%, t10 = -3.11, P = .011) and posttest 2 (74.2% ± 4.77%, t10 = -3.78, P = .004). LESS scores significantly improved over time (F2,10 = 6.29, P = .009). The pretest LESS score (7.30 ± 3.40) was higher than posttest 1 (4.9 ± 1.20, t10 = 2.71, P = .024) and posttest 2 (5.44 ± 1.83, t10 = 2.58, P = .030). There were no statistically significant differences (P > .05) over time for the H:Q ratio when averaging both legs (F2,10 = 0.83, P = .45). A 6-wk NMC program improved landing mechanics and dynamic balance over a 9-mo period in women's basketball players. NMC adaptations can be retained without an in-season maintenance program.

Diagnostic Tests to Support Late-Stage Control Programs for Schistosomiasis and Soil-Transmitted Helminthiases.

2016-12-01

Global efforts to address schistosomiasis and soil-transmitted helminthiases (STH) include deworming programs for school-aged children that are made possible by large-scale drug donations. Decisions on these mass drug administration (MDA) programs currently rely on microscopic examination of clinical specimens to determine the presence of parasite eggs. However, microscopy-based methods are not sensitive to the low-intensity infections that characterize populations that have undergone MDA. Thus, there has been increasing recognition within the schistosomiasis and STH communities of the need for improved diagnostic tools to support late-stage control program decisions, such as when to stop or reduce MDA. Failure to adequately address the need for new diagnostics could jeopardize achievement of the 2020 London Declaration goals. In this report, we assess diagnostic needs and landscape potential solutions and determine appropriate strategies to improve diagnostic testing to support control and elimination programs. Based upon literature reviews and previous input from experts in the schistosomiasis and STH communities, we prioritized two diagnostic use cases for further exploration: to inform MDA-stopping decisions and post-MDA surveillance. To this end, PATH has refined target product profiles (TPPs) for schistosomiasis and STH diagnostics that are applicable to these use cases. We evaluated the limitations of current diagnostic methods with regards to these use cases and identified candidate biomarkers and diagnostics with potential application as new tools. Based on this analysis, there is a need to develop antigen-detecting rapid diagnostic tests (RDTs) with simplified, field-deployable sample preparation for schistosomiasis. Additionally, there is a need for diagnostic tests that are more sensitive than the current methods for STH, which may include either a field-deployable molecular test or a simple, low-cost, rapid antigen-detecting test.

Space Shuttle Upgrades: Long Life Alkaline Fuel Cell

NASA Technical Reports Server (NTRS)

McCurdy, Kerri

2004-01-01

NASA has utilized the alkaline fuel cell technology to provide electrical power for manned launch vehicles such as Gemini, Apollo, and the Space Shuttle. The current Shuttle alkaline fuel cells are procured from UTC Fuel Cells, a United Technologies Company. The alkaline fuel cells are very reliable but the operating life is limited to 2600 hours due to voltage degradation of the individual cells. The main limiting factor in the life of the cells is corrosion of the cell's fiberglass/epoxy frame by the aqueous potassium hydroxide electrolyte. To reduce operating costs, the orbiter program office approved the Long Life Alkaline Fuel Cell (LLAFC) program as a shuttle upgrade in 1999 to increase the operating life of the fuel cell powerplant to 5000 hours. The LLAFC program incorporates improving the cell by extending the length of the corrosion path, which reduces the cell frame corrosion. UTCFC performed analysis to understand the fundamental mechanisms that drive the cell frame corrosion. The analysis indicated that the corrosion path started along the bond line between the cathode and the cell frame. Analysis also showed that the oxygen available at the cathode, the catalyst on the electrode, and the electrode substrate all supported or intensified the corrosion. The new cell design essentially doubled the corrosion path to mitigate the problem. A 10-cell stack was tested for 5000 hours during the development phase of this program to verify improved cell performance. A complete 96-cell stack was then tested for 5000 hours during the full manned-space qualification phase of this program. Additional upgrades to the powerplant under this program are: replacing the aluminum body in the pressure regulator with stainless steel to reduce corrosion, improving stack insulator plate with improved resistance to stress failure and improved temperature capability, and replacing separator plate elastomer seals with a more durable material and improved seal retention.

Purpose The purpose of this study is to test the feasibility of conducting a community-based randomized controlled trial evaluating a culturally tailored community-based group diabetes self-management education (DSME) program among rural African Americans. Methods Thirty-two African American rural adults with type 2 diabetes were recruited and 25 adults were retained and participated in an interventional study designed to test the effectiveness of the “Taking Care of Sugar” DSME program for the 2-year follow-up. Participants were selected from rural central Virginia. Primary outcomes variables included average blood sugar levels, cardiovascular risk factors, and general physical and mental health. These outcomes were assessed at baseline, 3 months, 6 months, and 12 months post baseline. Results From baseline to 3-month follow-up assessment, participants exhibited significant improvement on several physiological and behavioral measures. Given the small sample size, hypothesis testing was limited. Results show change from baseline over time, illustrating that the primary outcome of A1C decreased, although not significant. Additionally, participants reported more knowledge about diabetes self-management and personal care skills (ie, exercise and foot care) that persisted over time. The feasibility of the culturally tailored DSME was established, and participation with the program was high. Conclusions A community-based group DSME program using storytelling is feasible. This research will help to inform clinicians and health policymakers as to the types of interventions that are feasible in a larger rural population. If such a program is carried out, we can improve knowledge, reduce complications, and improve quality of life among rural African Americans. PMID:24478047

To determine whether an activity specific exercise program could improve ability to perform basic mobility activities in long-term care residents with Alzheimer disease (AD). Randomized, controlled, single-blinded clinical trial. Residents of 7 long-term care facilities. Eighty-two long-term care residents with mild to severe AD. An activity specific exercise program was compared to a walking program and to an attention control. Ability to perform bed mobility and transfers was assessed using the subscales of the Acute Care Index of Function; functional mobility was measured using the 6-Minute Walk test. Subjects receiving the activity specific exercise program improved in ability to perform transfers, whereas subjects in the other 2 groups declined.

Evaluation of new multimedia formats for cancer communications.

Providing quality, current cancer information to cancer patients and their families is a key function of the National Cancer Institute (NCI) Web site. This information is now provided in predominantly-text format, but could be provided in formats using multimedia, including animation and sound. Since users have many choices about where to get their information, it is important to provide the information in a format that is helpful and that they prefer. To pilot and evaluate multimedia strategies for future cancer-information program formats for lay users, the National Cancer Institute created new multimedia versions of existing text programs. We sought to evaluate user performance and preference on these 3 new formats and on the 2 existing text formats. The National Cancer Institute's "What You Need to Know About Lung Cancer" program was the test vehicle. There were 5 testing sessions, 1 dedicated to each format. Each session lasted about 1 hour, with 9 participants per session and 45 users overall. Users were exposed to the assigned cancer program from beginning to end in 1 of 5 formats: text paperback booklet, paperback booklet formatted in HTML on the Web, spoken audio alone, spoken audio synchronized with a text Web page, and Flash multimedia (animation, spoken audio, and text). Immediately thereafter, the features and design of the 4 alternative formats were demonstrated in detail. A multiple-choice pre-test and post-test quiz on the cancer content was used to assess user learning (performance) before and after experiencing the assigned program. The quiz was administered using an Authorware software interface writing to an Access database. Users were asked to rank from 1 to 5 their preference for the 5 program formats, and provide structured and open-ended comments about usability of the 5 formats. Significant improvement in scores from pre-test to post-test was seen for the total study population. Average scores for users in each of the 5 format groups improved significantly. Increments in improvement, however, were not statistically different between any of the format groups. Significant improvements in quiz scores were seen irrespective of age group or education level. Of the users, 71.1% ranked the Flash program first among the 5 formats, and 84.4% rated Flash as their first or second choice. Audio was the least-preferred format, ranking fifth among 46.7% of users and first among none. Flash was ranked first among users regardless of education level, age group, or format group to which the user was assigned. Under the pilot study conditions, users overwhelmingly preferred the Flash format to the other 4 formats. Learning occurred equally in all formats. Use of multimedia should be considered as communication strategies are developed for updating cancer content and attracting new users.

2016-01-01

PURPOSE The aim was to determine the feasibility of a six-week speed-based exercise program that could be used to initiate new exercise behaviors and improve rapid movement in older adults approaching frailty. METHODS The intervention group included 14 older adults (3 males, 11 females, mean (SD) age: 70 (7.6) years, height: 1.6 (.11) m, mass: 76.8 (12.0) kg, BMI: 27.7(4.7)). The control group included 12 older adults (6 males, 6 females, mean (SD) age: 69.2 (6.9) years, height: 1.7 (.09) m, mass: 78.2 (10.9) kg, BMI: 25.3 (2.7)). Subjects included active older adults, including regular exercisers, but none were engaged in sports or exercises with an emphasis on speed (e.g. cycling spin classes or tennis). Stationary recumbent cycling was selected to minimize fall risk and low pedaling resistance reduced musculoskeletal and cardiovascular load. Two weekly 30-minute exercise sessions consisted of interval training in which subjects pedaled at preferred cadence and performed ten 20-s fast cadence intervals separated by 40-s of active recovery at preferred cadence. RESULTS Significant Group by Time interactions (p<.05) supported a 2-s improvement in the timed up and go test and a 34% improvement in rapid isometric knee extension contractions in the exercise group but not in controls. Central neural adaptations are suggested because this lower extremity exercise program also elicited significant improvements in the untrained upper extremities of the exercise group (elbow extension RFD-SF and 9-Hole Peg Test, p<.05). CONCLUSION These results demonstrate that a relatively low dose of speed-based exercise can improve neuromuscular function and tests of mobility in older adults. Such a program serves as a sensible precursor to subsequent, more vigorous training or as an adjunct to a program where a velocity emphasis is lacking. PMID:27501360

This study examined the effectiveness of Ballates training (strengthening of the central core musculature by the inception of balance techniques) compared to more traditional exercise programs, such as step aerobics and walking, on balance in women aged 50- 75 years. Participants were randomly assigned to one of three supervised training groups (1 hour/day, 3 days/week, 13 weeks), Ballates (n = 12), step aerobics (n = 17), or walking (n =15). Balance was measured by four different methods (modified Clinical Test for the Sensory Interaction on Balance - mCTSIB; Unilateral Stance with Eyes Open - US-EO or Eyes Closed - US-EC; Tandem Walk - TW; Step Quick Turn - SQT) using the NeuroCom Balance Master. A 2-way (Group and Trial) repeated measures ANOVA and post-hoc Bonferroni Pair-wise Comparisons were used to evaluate changes in the dependent variables used to describe stability and balance (sway velocity, turn sway, speed, and turn time). Measures of static postural stability and dynamic balance were similar for the three groups prior to training. Following the different exercise interventions, sway velocity on firm and foam surfaces (mCTSIB) with eyes closed (p < 0.05) increased for the Ballates group while the other two exercise groups either maintained or decreased their sway velocity following the training, therefore suggesting that these two groups either maintained or improved their balance. There were significant improvements in speed during the TW test (p < 0.01), and turn time (p < 0.01) and sway (p < 0.05) during the SQT test for each of the three groups. In general, all three training programs improved dynamic balance, however, step aerobics and walking programs resulted in be better improvements in postural stability or static balance when compared to the Ballates program. Key PointsExercise training can improve balanceNeed to consider both static and dynamic aspects of balance individuallyImproved balance can reduce the risk of fall.

Extravehicular Mobility Unit Penetration Probability from Micrometeoroids and Orbital Debris: Revised Analytical Model and Potential Space Suit Improvements

Chase, Thomas D.; Splawn, Keith; Christiansen, Eric L.

2007-01-01

The NASA Extravehicular Mobility Unit (EMU) micrometeoroid and orbital debris protection ability has recently been assessed against an updated, higher threat space environment model. The new environment was analyzed in conjunction with a revised EMU solid model using a NASA computer code. Results showed that the EMU exceeds the required mathematical Probability of having No Penetrations (PNP) of any suit pressure bladder over the remaining life of the program (2,700 projected hours of 2 person spacewalks). The success probability was calculated to be 0.94, versus a requirement of >0.91, for the current spacesuit s outer protective garment. In parallel to the probability assessment, potential improvements to the current spacesuit s outer protective garment were built and impact tested. A NASA light gas gun was used to launch projectiles at test items, at speeds of approximately 7 km per second. Test results showed that substantial garment improvements could be made, with mild material enhancements and moderate assembly development. The spacesuit s PNP would improve marginally with the tested enhancements, if they were available for immediate incorporation. This paper discusses the results of the model assessment process and test program. These findings add confidence to the continued use of the existing NASA EMU during International Space Station (ISS) assembly and Shuttle Operations. They provide a viable avenue for improved hypervelocity impact protection for the EMU, or for future space suits.

A Systems Engineering Approach to Quality Assurance for Aerospace Testing

NASA Technical Reports Server (NTRS)

Shepherd, Christena C.

2015-01-01

On the surface, it appears that AS91001 has little to say about how to apply a Quality Management System (QMS) to major aerospace test programs (or even smaller ones). It also appears that there is little in the quality engineering Body of Knowledge (BOK)2 that applies to testing, unless it is nondestructive examination (NDE), or some type of lab or bench testing associated with the manufacturing process. However, if one examines: a) how the systems engineering (SE) processes are implemented throughout a test program; and b) how these SE processes can be mapped to the requirements of AS9100, a number of areas for involvement of the quality professional are revealed. What often happens is that quality assurance during a test program is limited to inspections of the test article; what could be considered a manufacturing al fresco approach. This limits the quality professional and is a disservice to the programs and projects, since there are a number of ways that quality can enhance critical processes, and support efforts to improve risk reduction, efficiency and effectiveness.

Quality assurance (QA) is a systematic process to monitor and improve clinical laboratory practices. The fundamental components of a laboratory QA program include providing a functional and safe laboratory environment, trained and competent personnel, maintained equipment, adequate supplies and reagents, testing of appropriate specimens, internal monitoring of quality, accurate reporting, and external quality assessments. These components are necessary to provide accurate and precise CD4 T-cell counts, an essential test to evaluate start of and monitor effectiveness of antiretroviral therapy for HIV-infected patients. In recent years, CD4 testing has expanded dramatically in resource-limited settings. Information on a CD4 QA program as described in this article will provide guidelines not only for clinical laboratory staff but also for managers of programs responsible for supporting CD4 testing. All agencies involved in implementing CD4 testing must understand the needs of the laboratory and provide advocacy, guidance, and financial support to established CD4 testing sites and programs. This article describes and explains the procedures that must be put in place to provide reliable CD4 determinations in a variety of settings.

This study reports on the impact evaluation of a Web-based oral health promotion programme aimed at improving the oral health knowledge, attitudes, practices and self-efficacy of independent-living older adults from Melbourne, Australia. With ethics approval from the University of Melbourne, a convenience sample of volunteers 55 years or older was invited to participate in a study to test a web-based oral health promotion program. Consenting volunteers were asked to undergo a structured interview as part of the pre-intervention data collection. The intervention was based on the ORHIS (Oral Health Information Seminars/Sheets) Model and involved computer interaction with six oral health presentations, with no direct oral health professional input. A one group pre-test-post-test quasi-experimental design was chosen to evaluate the intervention. A series of paired t-tests were used to compare pre-test with post-test results. Forty-seven active, independent-living older adults participated in this evaluation. After the intervention participants responded with higher levels of achievement than before participating in this Web-based oral health program. Participants showed significant improvements in oral health attitudes (4.10 vs. 4.94; p<0.01), knowledge (18.37 vs. 23.83; p<0.0001), and self-efficacy (84.37 vs.89.23; p<0.01), as well as, self-reported oral hygiene practices (i.e., frequency of use of dental floss) (p<0.05). The e-ORHIS approach was successful in improving oral health knowledge, attitudes and self-efficacy. As such, it represents a helpful approach for the design of (oral) health interventions in older adults. Further evaluation with a larger sample is required to test the long-term impact including the economic evaluation of the e-ORHIS approach. Copyright © 2016 Elsevier Ireland Ltd.

Whalen, Thomas J.

1989-01-01

The development of high strength, high reliability silicon carbide parts with complex shapes suitable for use in advanced heat engines is studied. Injection molding was the forming method selected for the program because it is capable of forming complex parts adaptable for mass production on an economically sound basis. The goals were to reach a Weibull characteristic strength of 550 MPa (80 ksi) and a Weibull modulus of 16 for bars tested in four-point loading. Statistically designed experiments were performed throughout the program and a fluid mixing process employing an attritor mixer was developed. Compositional improvements in the amounts and sources of boron and carbon used and a pressureless sintering cycle were developed which provided samples of about 99 percent of theoretical density. Strengths were found to improve significantly by annealing in air. Strengths in excess of 550 MPa (80 ksi) with Weibull modulus of about 9 were obtained. Further improvements in Weibull modulus to about 16 were realized by proof testing. This is an increase of 86 percent in strength and 100 percent in Weibull modulus over the baseline data generated at the beginning of the program. Molding yields were improved and flaw distributions were observed to follow a Poisson process. Magic angle spinning nuclear magnetic resonance spectra were found to be useful in characterizing the SiC powder and the sintered samples. Turbocharger rotors were molded and examined as an indication of the moldability of the mixes which were developed in this program.

The objective of the program is to develop rear stage blading designs that have lower losses in their endwall boundary layer regions. The overall technical approach in this efficiency improvement program utilized General Electric's Low Speed Research Compressor as the principal investigative tool. Tests were conducted in two ways: using four identical stages of blading so that test data would be obtained in a true multistage environment and using a single stage of blading so that comparison with the multistage test results could be made.

Integration of propulsion and flight control systems and their optimization offers significant performance improvements. Research programs were conducted which have developed new propulsion and flight control integration concepts, implemented designs on high-performance airplanes, demonstrated these designs in flight, and measured the performance improvements. These programs, first on the YF-12 airplane, and later on the F-15, demonstrated increased thrust, reduced fuel consumption, increased engine life, and improved airplane performance; with improvements in the 5 to 10 percent range achieved with integration and with no changes to hardware. The design, software and hardware developments, and testing requirements were shown to be practical.

Image-guided cochlear implant (CI) programming can improve hearing outcomes for pediatric CI recipients. CIs have been highly successful for children with severe-to-profound hearing loss, offering potential for mainstreamed education and auditory-oral communication. Despite this, a significant number of recipients still experience poor speech understanding, language delay, and, even among the best performers, restoration to normal auditory fidelity is rare. Although significant research efforts have been devoted to improving stimulation strategies, few developments have led to significant hearing improvement over the past two decades. Recently introduced techniques for image-guided CI programming (IGCIP) permit creating patient-customized CI programs by making it possible, for the first time, to estimate the position of implanted CI electrodes relative to the nerves they stimulate using CT images. This approach permits identification of electrodes with high levels of stimulation overlap and to deactivate them from a patient's map. Previous studies have shown that IGCIP can significantly improve hearing outcomes for adults with CIs. The IGCIP technique was tested for 21 ears of 18 pediatric CI recipients. Participants had long-term experience with their CI (5 mo to 13 yr) and ranged in age from 5 to 17 years old. Speech understanding was assessed after approximately 4 weeks of experience with the IGCIP map. Using a two-tailed Wilcoxon signed-rank test, statistically significant improvement (p < 0.05) was observed for word and sentence recognition in quiet and noise, as well as pediatric self-reported quality-of-life (QOL) measures. Our results indicate that image guidance significantly improves hearing and QOL outcomes for pediatric CI recipients.

With the passage of the Affordable Care Act, The Centers for Medicare and Medicaid (CMS) introduced a new value-based payment model, the Bundle Payment Care Initiative. The CMS Innovation (Innovation Center) authorized hospitals to participate in a pilot to test innovative payment and service delivery models that have a potential to reduce Medicare expenditures while maintaining or improving the quality of care for beneficiaries. A hospital-based home care agency, Abington Jefferson Health Home Care Department, led the initiative for the development and implementation of the Bundled Payment Program. This was a creative and innovative method to improve care along the continuum while testing a value-based care model.

The disproportionately large number of traffic accidents of young novice drivers highlights the need for an effective driver education program. The Goals for Driving Education (GDE) matrix shows that driver education must target both lower and higher levels of driver competences. Research has indicated that current education programs do not emphasize enough the higher levels, for example awareness and insight. This has raised the importance of insight programs. On the Road (OtR), a Flemish post-license driver education program, is such an insight program that aims to target these higher levels. The program focus is on risky driving behavior like speeding and drink driving. In addition, the program addresses risk detection and risk-related knowledge. The goal of the study was to do an effect evaluation of this insight program at immediate post-test and 2 months follow-up. In addition, the study aimed to generalize the results of this program to comparable programs in order to make usable policy recommendations. A questionnaire based on the Theory of Planned Behavior (TPB) was used in order to measure participants' safety consciousness of speeding and drink driving. Moreover, we focused on risk detection and risk-related knowledge. Participants (N=366) were randomly assigned to a baseline-follow-up group or a post-test-follow-up group. Regarding speeding and driving, we found OtR to have little effect on the TPB variables. Regarding risk detection, we found no significant effect, even though participants clearly needed substantial improvement when stepping into the program. Regarding risk-related knowledge, the program did result in a significant improvement at post-test and follow-up. It is concluded that the current program format is a good starting point, but that it requires further attention to enhance high level driving skills. Program developers are encouraged to work in a more evidence-based manner when they select target variables and methods to influence these variables. Copyright © 2014 Elsevier Ltd.

Our long-term objective is to develop an auditory training program that will enhance speech recognition in those situations where patients most want improvement. As a first step, the current investigation trained participants using either a single talker or multiple talkers to determine if auditory training leads to transfer-appropriate gains. The experiment implemented a 2 × 2 × 2 mixed design, with training condition as a between-participants variable and testing interval and test version as repeated-measures variables. Participants completed a computerized six-week auditory training program wherein they heard either the speech of a single talker or the speech of six talkers. Training gains were assessed with single-talker and multi-talker versions of the Four-choice discrimination test. Participants in both groups were tested on both versions. Sixty-nine adult hearing-aid users were randomly assigned to either single-talker or multi-talker auditory training. Both groups showed significant gains on both test versions. Participants who trained with multiple talkers showed greater improvement on the multi-talker version whereas participants who trained with a single talker showed greater improvement on the single-talker version. Transfer-appropriate gains occurred following auditory training, suggesting that auditory training can be designed to target specific patient needs.

The details of a study to develop accurate and efficient numerical schemes to predict complex flows are described. In this program, several discretization schemes were evaluated using simple test cases. This assessment led to the selection of three schemes for an in-depth evaluation based on two-dimensional flows. The scheme with the superior overall performance was incorporated in a computer program for three-dimensional flows. To improve the computational efficiency, the selected discretization scheme was combined with a direct solution approach in which the fluid flow equations are solved simultaneously rather than sequentially.

Flight related low back pain (LBP) among helicopter pilots is frequent and may influence flight performance. Prolonged confined sitting during flights seems to weaken lumbar trunk (LT) muscles with associated secondary transient pain. Aim of the study was to investigate if structured training could improve muscular function and thus improve LBP related to flying. 39 helicopter pilots (35 men and 4 women), who reported flying related LBP on at least 1 of 3 missions last month, were allocated to two training programs over a 3-month period. Program A consisted of 10 exercises recommended for general LBP. Program B consisted of 4 exercises designed specifically to improve LT muscular endurance. The pilots were examined before and after the training using questionnaires for pain, function, quality of health and tests of LT muscular endurance as well as ultrasound measurements of the contractility of the lumbar multifidus muscle (LMM). Approximately half of the participants performed the training per-protocol. Participants in this subset group had comparable baseline characteristics as the total study sample. Pre and post analysis of all pilots included, showed participants had marked improvement in endurance and contractility of the LMM following training. Similarly, participants had improvement in function and quality of health. Participants in program B had significant improvement in pain, function and quality of health. This study indicates that participants who performed a three months exercise program had improved muscle endurance at the end of the program. The helicopter pilots also experienced improved function and quality of health. Identifier: NCT01788111 Registration date; February 5th, 2013, verified April 2016.

Although there are many studies demonstrating increased trunk activation under unstable conditions, it is not known whether this increased activation would translate into meaningful trunk strength with a prolonged training program. Additionally, while balance-training programs have been shown to improve stability, their effect on specific joint proprioception is not clear. Thus the objective of this study was to examine training adaptations associated with a 10-week instability-training program. Participants were tested pre- and post-training for trunk extension and flexion strength and knee proprioception. Forty-three participants participated in either a 10-week (3 days per week) instability-training program using Swiss balls and body weight as resistance or a control group (n = 17). The trained group increased (p < 0. 05) trunk extension peak torque/body weight (23.6%) and total work output (20.1%) from pre- to post-training while the control group decreased by 6.8% and 6.7% respectively. The exercise group increased their trunk flexion peak torque/body weight ratios by 18.1% while the control group decreased by 0.4%. Knee proprioception (combined right and left joint repositioning) improved 44.7% from pre- to post-training (p = 0.0006) and persisted (21.5%) for 9 months post-training. In addition there was a side interaction with the position sense of the right knee at 9 months showing 32.1% (p = 0.03) less deviation from the reference angle than the right knee during pre-testing. An instability-training program using Swiss balls with body weight as resistance can provide prolonged improvements in joint proprioception and core strength in previously untrained individuals performing this novel training stress which would contribute to general health. Key pointsAlthough traditional free weight resistance exercises have been recommended as most beneficial for improving strength and power in athletes (Behm et al., 2010b), an IT program using Swiss balls and body weight as a resistance may provide an alternative starting point for the sedentary untrained population.As it is well documented that force or strength is decreased when unbalanced (Behm et al., 2010b) and balance-training programs improve balance (Behm and Kean 2006), this type of instability RT program can provide significant adaptations to improve trunk strength especially with the untrained.This type of training should also be incorporated into a new program as the improvements in joint proprioception may help protect from joint injuries over a protracted period.The finding that improved joint proprioception persists for months after training should be emphasized to those individuals whose training is regularly or inconsistently interrupted.

Although some studies have shown that cognitive training can produce improvements to untrained cognitive domains (far transfer), many others fail to show these effects, especially when it comes to improving fluid intelligence. The current study was designed to overcome several limitations of previous training studies by incorporating training expectancy assessments, an active control group, and “Mind Frontiers,” a video game-based mobile program comprised of six adaptive, cognitively demanding training tasks that have been found to lead to increased scores in fluid intelligence (Gf) tests. We hypothesize that such integrated training may lead to broad improvements in cognitive abilities by targeting aspects of working memory, executive function, reasoning, and problem solving. Ninety participants completed 20 hour-and-a-half long training sessions over four to five weeks, 45 of whom played Mind Frontiers and 45 of whom completed visual search and change detection tasks (active control). After training, the Mind Frontiers group improved in working memory n-back tests, a composite measure of perceptual speed, and a composite measure of reaction time in reasoning tests. No training-related improvements were found in reasoning accuracy or other working memory tests, nor in composite measures of episodic memory, selective attention, divided attention, and multi-tasking. Perceived self-improvement in the tested abilities did not differ between groups. A general expectancy difference in problem-solving was observed between groups, but this perceived benefit did not correlate with training-related improvement. In summary, although these findings provide modest evidence regarding the efficacy of an integrated cognitive training program, more research is needed to determine the utility of Mind Frontiers as a cognitive training tool.

1976-01-01

A Pollution Reduction Technology Program to develop and demonstrate the combustor technology necessary to reduce exhaust emissions for aircraft engines using can-annular combustors is described. The program consisted of design, fabrication, experimental rig testing and assessment of results and was conducted in three program elements. The combustor configurations of each program element represented increasing potential for meeting the 1979 Environmental Protection Agency (EPA) emission standards, while also representing increasing complexity and difficulty of development and adaptation to an operational engine. Experimental test rig results indicate that significant reductions were made to the emission levels of the baseline JT8D-17 combustor by concepts in all three program elements. One of the Element I single-stage combustors reduced carbon monoxide to a level near, and total unburned hydrocarbons (THC) and smoke to levels below the 1979 EPA standards with little or no improvement in oxides of nitrogen. The Element II two-stage advanced Vorbix (vortex burning and mixing) concept met the standard for THC and achieved significant reductions in CO and NOx relative to the baseline. Although the Element III prevaporized-premixed concept reduced high power NOx below the Element II results, there was no improvement to the integrated EPA parameter relative to the Vorbix combustor.

This randomized trial tested the efficacy of an intensive, four-week summer program designed to enhance low-income children's transition to kindergarten (n's = 60 program children, 40 controls). Administered in four public schools, the program focused on social competence, pre-literacy and pre-numeracy skills, school routines, and parental involvement. Hierarchical linear modeling indicated that the program significantly improved teachers’ ratings of (a) the transition to the social aspect of kindergarten for girls (but not boys); and (b) the transition to kindergarten routines for the subgroup of children who had the same teacher for kindergarten as for the summer program. Findings are discussed in terms of practices and policies for supporting children's transition to school. PMID:21969767

Test Planning Approach and Lessons

Parkinson, Douglas A.; Brown, Kendall K.

2004-01-01

As NASA began technology risk reduction activities and planning for the next generation launch vehicle under the Space Launch Initiative (SLI), now the Next Generation Launch Technology (NGLT) Program, a review of past large liquid rocket engine development programs was performed. The intent of the review was to identify any significant lessons from the development testing programs that could be applied to current and future engine development programs. Because the primary prototype engine in design at the time of this study was the Boeing-Rocketdyne RS-84, the study was slightly biased towards LOX/RP-1 liquid propellant engines. However, the significant lessons identified are universal. It is anticipated that these lessons will serve as a reference for test planning in the Engine Systems Group at Marshall Space Flight Center (MSFC). Towards the end of F-1 and J-2 engine development testing, NASA/MSFC asked Rocketdyne to review those test programs. The result was a document titled, Study to Accelerate Development by Test of a Rocket Engine (R-8099). The "intent (of this study) is to apply this thinking and learning to more efficiently develop rocket engines to high reliability with improved cost effectivenes" Additionally, several other engine programs were reviewed - such as SSME, NSTS, STME, MC-1, and RS-83- to support or refute the R-8099. R-8099 revealed two primary lessons for test planning, which were supported by the other engine development programs. First, engine development programs can benefit from arranging the test program for engine system testing as early as feasible. The best test for determining environments is at the system level, the closest to the operational flight environment. Secondly, the component testing, which tends to be elaborate, should instead be geared towards reducing risk to enable system test. Technical risk can be reduced at the component level, but the design can only be truly verified and validated after engine system testing.

Objectives. To determine the effects on balance and gait of a Wii-Fit program compared to a walking program in subjects with mild Alzheimer's dementia (AD). Methods. A prospective randomized (1 : 1) pilot study with two intervention arms was conducted in an assisted living facility with twenty-two mild AD subjects. In both groups the intervention occurred under supervision for 30 minutes daily, five times a week for eight weeks. Repeated measures ANOVA and paired t-tests were used to analyze changes. Results. Both groups showed improvement in Berg Balance Scale (BBS), Tinetti Test (TT) and Timed Up and Go (TUG) over 8 weeks. However, there was no statistically significant difference between the groups over time. Intragroup analysis in the Wii-Fit group showed significant improvement on BBS (P = 0.003), and TT (P = 0.013). The walking group showed a trend towards improvement on BBS (P = 0.06) and TUG (P = 0.07) and significant improvement in TT (P = 0.06). Conclusion. This pilot study demonstrates the safety and efficacy of Wii-Fit in an assisted living facility in subjects with mild AD. Use of Wii-Fit resulted in significant improvements in balance and gait comparable to those in the robust monitored walking program. These results need to be confirmed in a larger, methodologically sound study. PMID:22745909

Deficits in emotion perception are common in people with schizophrenia and current research has focused on improving these deficits. In our previous research, we demonstrated that directing attention to salient facial features via attention shaping can improve these deficits among inpatients. In this study, we examined the efficacy of an enhanced attention shaping program that contains 192 emotional expressions from which 25 are randomly presented for training. We extended our previous work by using repeated administrations of the shaping intervention and testing its effect in outpatients with schizophrenia and impaired controls. Fifteen participants with schizophrenia and fourteen college student controls with emotion perception deficits were randomly assigned to 1, 3 or 5 sessions of attention shaping. Participants completed 2 outcome measures of emotion perception, the FEIT and BLERT, not presented during the training, and underwent eye tracking at pre and post-tests. All conditions and groups improved, but the largest improvements on the BLERT and FEIT were found for persons assigned to the 5 session condition. Performance on the shaping program was positively correlated with the two outcome measures of emotion perception. There was less support for changes in visual scanning of faces as there was a relative reduction in total scanning time from pre-test to post-test. Results are interpreted in terms of the efficacy of attention shaping as a means to improve emotion perception deficits. Copyright © 2010 Elsevier B.V. All rights reserved.

The purpose of this study was to examine the effects of a cultural competence improvement program for maternity nurses. A quasi-experimental study using a non-equivalent control group pre and posttest design was used. Participants were 67 maternity nurses caring for multicultural pregnant women in G city. The cultural competence improvement program was developed based on the 3-D Puzzle Model and was provided using case-based small group learning methods for the experimental group (n=31). The control group (n=36) did not receive any intervention. Data were collected using self-report structured questionnaires at two time points: prior to the intervention and after the intervention and were analyzed with descriptive statistics, χ²-test, and t-test. Compared to the control group, the experimental group reported significant positive changes for cultural knowledge (t=6.39, p<.001), cultural awareness (t=3.50, p<.001), and cultural acceptance (t=4.08, p<.001). However, change in cultural nursing behaviors (t=0.92, p=.067) was not significantly different between the two groups. Findings from this study indicate that a cultural competence improvement program with case-based small group learning is a useful intervention strategy to promote multicultural maternity care. Further, strategies to improve cultural nursing behavior should be developed to promote culturally congruent nursing care.

The Light and Optics Conceptual Evaluation (LOCE) was developed to examine conceptual understanding of basic geometric and physical optics for the Active Learning in Optics and Photonics program administered by UNESCO. This 50 item test (46 multiple choice, 4 ray-tracing short answer) was administered to entering students in the Optometry professional degree (OD) program. We wanted to determine how much of the physics/optics concepts from undergraduate physics courses (a pre-requisite for entry to the OD program) were retained. In addition, the test was administered after the first year students had taken a required course in geometric and visual optics as part of their first semester courses. The LOCE was completed by two consecutive classes to the program in 2010 (n=89) and 2011 (n=84). The tests were administered the first week of the term and the test was given without any prior notice. In addition, the test was administered to the class of 2010 students after they had completed the course in geometric and visual optics. The means of the test were 22.1 (SD=4.5; range: 12-35) and 21.3(SD=5.1; range: 11-35) for the two entering classes. There was no statistical significance between the two classes (t-test, p<0.05). Similarly there was no difference between the scores in terms of gender. The post-course test (administered during the first week of the second term) showed a statistically significant improvement (mean score went from 22.1 to 31.1, a 35% improvement). It should be noted that both groups of students performed worse in questions related to physical optics as well as lens imaging, while scoring best in questions related to refraction and reflection. These data should be taken into consideration when designing optics curricula for optometry (and other allied health programs such as opticianry or ophthalmology).

The KC-135A Winglet Flight Research and Demonstration Program was a joint effort of the Air Force, NASA and the Boeing Military Airplane Company to flight test winglets on the KC-135A. The primary objective of the program was to verify the cruise performance improvements predicted by analysis and wind tunnel tests. Flight test data were obtained for winglets positioned at 15 deg cant/-2 deg incidence, 0 deg cant/-4 deg incidence, 15 deg cant/-4 deg incidence and for winglets off (baseline). Both fuel mileage and drag measurements were obtained. The 15 deg cant/-4 deg incidence winglet configuration provided the greatest performance improvement. The flight test measured fuel mileage improvement for a 0.78 Mach number was 3.1 percent at 8 x 10(5) pounds W/delta and 5.5 percent at 1.05 x 10(6) pounds W/delta. Correcting the flight measured data for surface pressure differences between wind tunnel and flight resulted in a fuel mileage improvement of 4.4 percent at 8 x 10(5) pounds W/delta and 7.2 percent at 1.05 x 10(6) pounds W/delta. The agreement between the fuel mileage and drag data was excellent.

Pasos Adelante is a lifestyle intervention program facilitated by community health workers (promotores) targeting chronic disease prevention and control in Mexican Americans. Initial studies of Pasos Adelante indicated significant improvements in self-reported nutrition and physical activity. This study examined whether Pasos Adelante participants living in a US border community showed improvements in selected physiological measures after participating in the program and whether changes were maintained at 3-month follow-up. The program took place in 12-week sessions from January 2005 to May 2008 and included walking groups and education targeting nutrition and physical activity. Questionnaires, anthropometric measures, and laboratory tests were conducted at baseline (n = 305), conclusion of program (n = 254), and 3-month follow-up (n = 221). Participants demonstrated decreases in body mass index (P = .04), waist and hip circumference (P < .001), diastolic and systolic blood pressure (P < .001), and total cholesterol (P = .008) from baseline to program conclusion. No values worsened significantly between program conclusion and follow-up, except systolic blood pressure. Glucose levels improved between conclusion and follow-up (P = .01). These results support the initial findings of improvements in participants' self-reported physical activity and nutrition patterns through changes in objective measures. This evidence-based program demonstrates the potential for a promotores-facilitated chronic disease prevention and control program to improve physical health and targets both primary and secondary prevention in Hispanic communities and organizations.

1979-01-01

The Low-Cost Solar Array (LSA) Project at the Jet Propulsion Laboratory has as one objective: the development and implementation of environmental tests for flat plate photovoltaic modules as part of the Department of Energy's terrestrial photovoltaic program. Modules procured under this program have been subjected to a variety of laboratory tests intended to simulate service environments, and the results of these tests have been compared to available data from actual field service. This comparison indicates that certain tests (notably temperature cycling, humidity cycling, and cyclic pressure loading) are effective indicators of some forms of field failures. Other tests have yielded results useful in formulating module design guidelines. Not all effects noted in field service have been successfully reproduced in the laboratory, however, and work is continuing in order to improve the value of the test program as a tool for evaluating module design and workmanship. This paper contains a review of these ongoing efforts and an assessment of significant test results to date.

Objective. To develop, implement, and evaluate “Test2Learn” a program to enhance pharmacogenomics education through the use of personal genomic testing (PGT) and real genetic data. Design. One hundred twenty-two second-year doctor of pharmacy (PharmD) students in a required course were offered PGT as part of a larger program approach to teach pharmacogenomics within a robust ethical framework. The program added novel learning objectives, lecture materials, analysis tools, and exercises using individual-level and population-level genetic data. Outcomes were assessed with objective measures and pre/post survey instruments. Assessment. One hundred students (82%) underwent PGT. Knowledge significantly improved on multiple assessments. Genotyped students reported a greater increase in confidence in understanding test results by the end of the course. Similarly, undergoing PGT improved student’s self-perceived ability to empathize with patients compared to those not genotyped. Most students (71%) reported feeling PGT was an important part of the course, and 60% reported they had a better understanding of pharmacogenomics specifically because of the opportunity. Conclusion. Implementation of PGT in the core pharmacy curriculum was feasible, well-received, and enhanced student learning of pharmacogenomics. PMID:26941429

Use of expenditure analysis to enhance returns on investments in HIV services.

Globally, the response to the HIV epidemic is at a crisis point. International investments in the HIV response have been essentially flat for 8 years and domestic budgets in low and middle-income countries - still recovering from the global recession - have not been able to fill the resource gap to drive a full-fledged HIV response. Still, efficiencies and prioritization of evidence-based interventions enable a significant scale-up of treatment, but millions more people remain without treatment. This review looks at recent data and research to evaluate interventions that may help close gaps in service provision that undermine testing and treatment programs. The President's Emergency Plan for AIDS Relief recently began publicly releasing vast programmatic and expenditure data. These data reveal potential efficiency gaps in testing and treatment programs, particularly in the area of linkage and retention. Interventions such as HIV self-testing have been proposed to help, but whether they can deliver better results remains unclear. Same-day initiation on treatment improves initiation, retention, and viral suppression rates. Near real-time analysis of data and active response is critical in improving efficiencies in programs. More investment in implementation research is necessary to improve linkage to care and treatment to reach 90-90-90 goals.

Integration Testing of Space Flight Systems

This paper discusses the benefits of conducting multi-system integration testing of space flight elements in lieu of merely shipping and shooting to the launch site and launching. "Ship and shoot" is a philosophy that proposes to transport flight elements directly from the factory to the launch site and begin the mission without further testing. Integration testing, relevant to validation testing in this context, is a risk mitigation effort that builds upon the individual element and system levels of qualification and acceptance tests, greatly improving the confidence of operations in space. The International Space Station Program (ISSP) experience is the focus of most discussions from a historical perspective, while proposed integration testing of the Constellation Program is also discussed. The latter will include Multi-Element Integration Testing (MElT) and Flight Element Integration Testing (FElT).

Point-of-care ultrasound has been shown to decrease the use of expensive diagnostic studies and improve quality outcome measures. Currently, there is a large desire for training in family medicine residencies, but very few programs have established curricula. We sought to develop a family medicine residency curriculum and evaluate it with tools we developed. We wanted our curriculum to be easy to adopt by other residency programs, even if they did not have many well-trained ultrasound faculty. We developed a curriculum in the form of a 4-week rotation in a family medicine residency program. It consisted of self-study videos, hands-on training, and image review. We followed residents in postgraduate years 1 to 3 over a 12-month period. We developed tools, including a knowledge exam, to test image interpretation and clinical decision making, an observed structured clinical exam to assess scanning skills, and a survey to assess perceptions of point-of-care ultrasound in family medicine. The assessments were administered before and after each resident's rotation. Seventeen residents completed the rotation. The average knowledge test score improved significantly, from 62 to 84%. The average observed structured clinical exam scores also improved significantly, from 41 to 85%. The average perception survey scores improved slightly from 4.4 to 4.6. We developed a point-of-care ultrasound curriculum for family medicine residency programs that improves measures of resident attitude, skills, and knowledge. This curriculum can be adopted by residency programs with few faculty members who are experienced in ultrasound. © 2017 by the American Institute of Ultrasound in Medicine.

Balance training is an effective intervention to improve static postural sway and balance. The purpose of the present study was to investigate the effectiveness of the Nintendo Wii Fit Plus exercises for improving balance ability in healthy collegiate students in comparison with a typical balance training program. Forty students were randomly divided into two groups, a traditional (T group) and a Nintendo Wii group (W group) performed an 8 week balance program. The "W group" used the interactive games as a training method, while the "T group" used an exercise program with mini trampoline and inflatable discs (BOSU). Pre and Post-training participants completed balance assessments. Two-way repeated measures analyses of variance (ANOVAs) were conducted to determine the effect of training program. Analysis of the data illustrated that both training program groups demonstrated an improvement in Total, Anterior-posterior and Medial Lateral Stability Index scores for both limbs. Only at the test performed in the balance board with anterior-posterior motion, the improvement in balance ability was greater in the "T group" than the "W group", when the assessment was performed post-training (p=0.023). Findings support the effectiveness of using the Nintendo Wii gaming console as a balance training intervention tool.

Difficulties with thinking and problem solving are very common among breast cancer survivors. We tested a computerized cognitive training program for 41 breast cancer survivors. The training program was associated with significant improvements in thinking and problem-solving skills. Our findings demonstrate potential for our online, home-based cognitive training program to improve cognitive difficulties among breast cancer survivors. Background A majority of breast cancer (BC) survivors, particularly those treated with chemotherapy, experience long-term cognitive deficits that significantly reduce quality of life. Among the cognitive domains most commonly affected include executive functions (EF), such as working memory, cognitive flexibility, multitasking, planning, and attention. Previous studies in other populations have shown that cognitive training, a behavioral method for treating cognitive deficits, can result in significant improvements in a number of cognitive skills, including EF. Materials and Methods In this study, we conducted a randomized controlled trial to investigate the feasibility and preliminary effectiveness of a novel, online EF training program in long-term BC survivors. A total of 41 BC survivors (21 active, 20 wait list) completed the 48 session training program over 12 weeks. The participants were, on average, 6 years after therapy. Results Cognitive training led to significant improvements in cognitive flexibility, verbal fluency and processing speed, with marginally significant downstream improvements in verbal memory as assessed via standardized measures. Self-ratings of EF skills, including planning, organizing, and task monitoring, also were improved in the active group compared with the wait list group. Conclusions Our findings suggest that EF skills may be improved even in long-term survivors by using a computerized, home-based intervention program. These improvements may potentially include subjective EF skills, which suggest a transfer of the training program to real-world behaviors. PMID:23647804

The construction and checkout of the National Transonic Facility (NTF) have been completed, and detailed calibration is now in progress. The initial NTF research program covers a wide range of study areas falling into three major elements: (1) the assessment of Reynolds number sensitivities for a broad range of configurations and flow phenomena; (2) validation of the ability of NTF to simulate full-scale aerodynamics; and (3) the development of test techniques for improved test simulations in existing wind tunnels. This paper, therefore, is a status report on these various elements of the initial NTF research program.

Nurse home visiting (NHV) offers a potential platform to both address the factors that limit access to services for families experiencing adversity and provide effective interventions. Currently, the ability to examine program implementation is hampered by a lack of detailed description of actual, rather than expected, program development and delivery in published studies. Home visiting implementation remains a black box in relation to quality and sustainability. However, previous literature would suggest that efforts to both report and improve program implementation are vital for NHV to have population impact and policy sustainability. In this paper, we provide a case study of the design, testing, and implementation of the right@home program, an Australian NHV program and randomized controlled trial. We address existing gaps related to implementation of NHV programs by describing the processes used to develop the program to be trialed, summarizing its effectiveness, and detailing the quality processes and implementation evaluation. The weight of our evidence suggests that NHV can be a powerful and sustainable platform for addressing inequitable outcomes, particularly when the program focuses on parent engagement and partnership, delivers evidence-based strategies shown to improve outcomes, includes fidelity monitoring, and is adapted to and embedded within existing service delivery systems. © 2018 The Authors.

Numerous digital health interventions have been developed for mental health promotion and intervention, including eating disorders. Efficacy of many interventions has been evaluated, yet knowledge about reasons for dropout and poor adherence is scarce. Most digital health intervention studies lack appropriate research design and methods to investigate individual engagement issues. User engagement and program usability are inextricably linked, making usability studies vital in understanding and improving engagement. The aim of this study was to explore engagement and corresponding usability issues of the Healthy Body Image Program-a guided online intervention for individuals with body image concerns or eating disorders. The secondary aim was to demonstrate the value of usability research in order to investigate engagement. We conducted an iterative usability study based on a mixed-methods approach, combining cognitive and semistructured interviews as well as questionnaires, prior to program launch. Two separate rounds of usability studies were completed, testing a total of 9 potential users. Thematic analysis and descriptive statistics were used to analyze the think-aloud tasks, interviews, and questionnaires. Participants were satisfied with the overall usability of the program. The average usability score was 77.5/100 for the first test round and improved to 83.1/100 after applying modifications for the second iteration. The analysis of the qualitative data revealed five central themes: layout, navigation, content, support, and engagement conditions. The first three themes highlight usability aspects of the program, while the latter two highlight engagement issues. An easy-to-use format, clear wording, the nature of guidance, and opportunity for interactivity were important issues related to usability. The coach support, time investment, and severity of users' symptoms, the program's features and effectiveness, trust, anonymity, and affordability were relevant to engagement. This study identified salient usability and engagement features associated with participant motivation to use the Healthy Body Image Program and ultimately helped improve the program prior to its implementation. This research demonstrates that improvements in usability and engagement can be achieved by testing and adjusting intervention design and content prior to program launch. The results are consistent with related research and reinforce the need for further research to identify usage patterns and effective means for reducing dropout. Digital health research should include usability studies prior to efficacy trials to help create more user-friendly programs that have a higher likelihood of "real-world" adoption.

EPA is also amending other sections of the Acid Rain Program continuous emission monitoring system regulations by adding and clarifying certain recordkeeping and reporting requirements, removing the provisions pertaining to mercury monitoring and reporting, removing certain requirements associated with a class-approved alternative monitoring system, disallowing the use of a particular quality assurance option in EPA Reference Method 7E, adding two incorporation by references that were inadvertently left out of the January 24, 2008 final rule, adding two new definitions, revising certain compliance dates, and clarifying the language and applicability of certain provisions.

The impact of middle manager affective commitment on perceived improvement program implementation success.

PubMed

Fryer, Ashley-Kay; Tucker, Anita L; Singer, Sara J

Recent literature suggests that middle manager affective commitment (emotional attachment, identification, and involvement) to an improvement program may influence implementation success. However, less is known about the interplay between middle manager affective commitment and frontline worker commitment, another important driver of implementation success. We contribute to this research by surveying middle managers who directly manage frontline workers on nursing units. We assess how middle manager affective commitment is related to their perceptions of implementation success and whether their perceptions of frontline worker support mediate this relationship. We also test whether a set of organizational support factors foster middle manager affective commitment. We adapt survey measures of manager affective commitment to our research context of hospitals. We surveyed 67 nurse managers from 19 U.S. hospitals. We use hierarchical linear regression to assess relationships among middle manager affective commitment to their units' falls reduction program and their perceptions of three constructs related to the program: frontline worker support, organizational support, and implementation success. Middle manager affective commitment to their unit's falls reduction program is positively associated with their perception of implementation success. This relationship is mediated by their perception of frontline worker support for the falls program. Moreover, middle managers' affective commitment to their unit's falls program mediates the relationship between perceived organizational support for the program and perceived implementation success. We, through this research, offer an important contribution by providing empirical support of factors that may influence successful implementation of an improvement program: middle manager affective commitment, frontline worker support, and organizational support for an improvement program. Increasing levels of middle manager affective commitment to an improvement program could strengthen program implementation success by facilitating frontline worker support for the program. Furthermore, providing the organizational support items in our survey construct may bolster middle manager affective commitment.

to evaluate the effect of a supervised rehabilitation program to improve gait, balance and independence in elderly patients attending a family medicine unit. we conducted a quasi-experimental study over a period of four weeks in a group of 72 patients older than 65 years. a supervised program regarding the risk factors for falling, and balance, gait, coordination and oculovestibular system, the modalities to be done two or three times a week in the primary care unit or at home. An analysis of both tests was performed by "up and go," Tinetti scale and the Katz index. "intention to treat" and "by protocol." mean age was 72 ± 5 years, 67.8% were female and 81.9% of the patients completed the program. A significant clinical improvement with statistical level were evident for gait and balance (p = 0.001), independence showed only clinical improvement (p = 0.083). The efficacy for periodicity (two or three times/week) and performance place showed same clinical improvement and statistical level for gait and balance (p = 0.001 to 0.003) and independence showed only clinical improvement (p = 0.317 to 0.991). an integral rehabilitation program improved gait, balance and clinical independence significantly. The supervised program is applicable and can be reproduced at primary care unit or home for geriatric care and preventive actions.
