Traditional Medicare Versus Private Insurance: How Spending, Volume, And Price Change At Age Sixty-Five.

PubMed

Wallace, Jacob; Song, Zirui

2016-05-01

To slow the growth of Medicare spending, some policy makers have advocated raising the Medicare eligibility age from the current sixty-five years to sixty-seven years. For the majority of affected adults, this would delay entry into Medicare and increase the time they are covered by private insurance. Despite its policy importance, little is known about how such a change would affect national health care spending, which is the sum of health care spending for all consumers and payers-including governments. We examined how spending differed between Medicare and private insurance using longitudinal data on imaging and procedures for a national cohort of individuals who switched from private insurance to Medicare at age sixty-five. Using a regression discontinuity design, we found that spending fell by $38.56 per beneficiary per quarter-or 32.4 percent-upon entry into Medicare at age sixty-five. In contrast, we found no changes in the volume of services at age sixty-five. For the previously insured, entry into Medicare led to a large drop in spending driven by lower provider prices, which may reflect Medicare's purchasing power as a large insurer. These findings imply that increasing the Medicare eligibility age may raise national health care spending by replacing Medicare coverage with private insurance, which pays higher provider prices than Medicare does.

Preliminary design of nine high speed civil transports

NASA Technical Reports Server (NTRS)

Sandlin, Doral; Vantriet, Robert; Soban, Dani; Hoang, TY

1992-01-01

Sixty senior design students at Cal Poly, SLO have completed a year-long project to design the next generation of High Speed Civil Transports (HSCT). The design process was divided up into three distinct phases. The first third of the project was devoted entirely to research into the special problems associated with an HSCT. These included economic viability, airport compatibility, high speed aerodynamics, sonic boom minimization, environmental impact, and structures and materials. The result of this research was the development of nine separate Requests for Proposal (RFP) that outlined reasonable yet challenging design criteria for the aircraft. All were designed to be technically feasible in the year 2015. The next phase of the project divided the sixty students into nine design groups. Each group, with its own RFP, completed a Class 1 preliminary design of an HSCT. The nine configurations varied from conventional double deltas to variable geometry wings to a pivoting oblique wing design. The final phase of the project included a more detailed Class 2 sizing as well as performance and stability and control analysis. Cal Poly, San Luis Obispo presents nine unique solutions to the same problem: that of designing an economically viable, environmentally acceptable, safe and comfortable supersonic transport.

The effect of Neuragen PN® on Neuropathic pain: A randomized, double blind, placebo controlled clinical trial

PubMed Central

2010-01-01

Background A double blind, randomized, placebo controlled study to evaluate the safety and efficacy of the naturally derived topical oil, "Neuragen PN®" for the treatment of neuropathic pain. Methods Sixty participants with plantar cutaneous (foot sole) pain due to all cause peripheral neuropathy were recruited from the community. Each subject was randomly assigned to receive one of two treatments (Neuragen PN® or placebo) per week in a crossover design. The primary outcome measure was acute spontaneous pain level as reported on a visual analog scale. Results There was an overall pain reduction for both treatments from pre to post application. As compared to the placebo, Neuragen PN® led to significantly (p < .05) greater pain reduction. Fifty six of sixty subjects (93.3%) receiving Neuragen PN® reported pain reduction within 30 minutes. This reduction within 30 minutes occurred in only twenty one of sixty (35.0%) subjects receiving the placebo. In a break out analysis of the diabetic only subgroup, 94% of subjects in the Neuragen PN® group achieved pain reduction within 30 minutes vs 11.0% of the placebo group. No adverse events were observed. Conclusions This randomized, placebo controlled, clinical trial with crossover design revealed that the naturally derived oil, Neuragen PN®, provided significant relief from neuropathic pain in an all cause neuropathy group. Participants with diabetes within this group experienced similar pain relief. Trial registration ISRCTN registered: ISRCTN13226601 PMID:20487567

2014-01-01

Objectives To evaluate pedestrian behavior, including reaction time, impulsivity, risk-taking, attention, and decision-making, in children with obstructive sleep apnea syndrome (OSAS) compared with healthy controls. Study design Using a case control design, sixty 8- to 16-year-olds with newly diagnosed and untreated OSAS engaged in a virtual reality pedestrian environment. Sixty-one healthy children matched using a yoke-control procedure by age, race, gender and household income served as controls. Results Children with OSAS were riskier pedestrians than healthy children of the same age, race, and sex. Children with OSAS waited less time to cross (p<.01). The groups did not differ in looking at oncoming traffic or taking longer to decide to cross. Conclusions Results suggest OSAS may have significant consequences on children’s daytime functioning in a critical domain of personal safety, pedestrian skills. Children with OSAS appeared to have greater impulsivity when crossing streets. Results highlight the need for heightened awareness of the consequences of untreated sleep disorders and identify a possible target for pediatric injury prevention. PMID:25444002

Anthropometric and biomechanical characteristics on body segments of Koreans.

PubMed

Park, S J; Kim, C B; Park, S C

1999-05-01

This paper documents the physical measurements of the Korean population in order to construct a data base for ergonomic design. The dimension, volume, density, mass, and center of mass of Koreans whose ages range from 7 to 49 were investigated. Sixty-five male subjects and sixty-nine female subjects participated. Eight body segments (head with neck, trunk, thigh, shank, foot, upper arm, forearm and hand) were directly measured with a Martin-type anthropometer, and the immersion method was adopted to measure the volume of body segments. After this, densities were computed by the density equations in Drillis and Contini (1966). The reaction board method was employed for the measurement of the center of mass. Obtained data were compared with the results in the literature. The results in this paper showed different features on body segment parameters comparing with the results in the literature. The constructed data base can be applied to statistical guideline for product design, workspace design, design of clothing and tools, furniture design and construction of biomechanical models for Korean. Also, they can be extended to the application areas for Mongolian.

The marketing implications of affective product design.

PubMed

Seva, Rosemary R; Duh, Henry Been-Lirn; Helander, Martin G

2007-11-01

Emotions are compelling human experiences and product designers can take advantage of this by conceptualizing emotion-engendering products that sell well in the market. This study hypothesized that product attributes influence users' emotions and that the relationship is moderated by the adherence of these product attributes to purchase criteria. It was further hypothesized that the emotional experience of the user influences purchase intention. A laboratory study was conducted to validate the hypotheses using mobile phones as test products. Sixty-two participants were asked to assess eight phones from a display of 10 phones and indicate their emotional experiences after assessment. Results suggest that some product attributes can cause intense emotional experience. The attributes relate to the phone's dimensions and the relationship between these dimensions. The study validated the notion of integrating affect in designing products that convey users' personalities.

The majority of hearing loss due to mumps presents as unilateral profound sensorineural hearing loss, which is refractory to treatment. In rare cases of bilateral total deafness, cochlear implants were beneficial for speech perception. Vaccination against mumps is recommended to prevent mumps-associated hearing loss. The objective of this study is to investigate the clinical characteristics of hearing loss due to mumps and to evaluate hearing outcomes. The clinical parameters were analyzed under a retrospective multi-institutional study design in patients diagnosed with hearing loss due to mumps at the Otolaryngology departments of 19 hospitals between 1987 and 2016. Sixty-seven patients with hearing loss due to mumps were enrolled. The study population consisted of 35 males and 32 females, ranging in age from 1 to 54, with a median age of 9.5 years. Sixty-three patients presented with unilateral, and 4 with bilateral hearing loss. Profound hearing loss was observed in 65 ears. Only one ear with severe hearing loss showed complete recovery. Four patients with bilateral hearing loss received cochlear implant surgery. Most of the patients with hearing loss due to mumps had no history of vaccination.

Integrated learning modules were introduced and baseline information was collected, in order to identify the expectations regarding e-learning. Furthermore, first formative evaluation of fourth-year dental students was conducted and the experience gained with summative online assessment was reported. Questionnaires designed by Infratest dimap (Berlin, Germany) were distributed to undergraduate students (n = 72) of the School of Dentistry. The fourth-year dental students went through a preliminary evaluation process. An online test was evaluated and compared with a traditional examination. Sixty-three questionnaires were returned. Sixty-five per cent of the students were already familiar with e-learning. All but one student owned at least one personal computer or laptop. Ninety-one per cent of the students expected positive effects from the integration of online modules. Enhanced flexibility regarding time and location as well as comfortable access to learning materials were mentioned most frequently. Ninety per cent of the students expected to achieve better results by finding it easier to understand learning materials produced with multimedia tools. Sixty per cent of the students feared technical complications when using an online platform. The online test was successfully performed. A formative evaluation process demonstrated agreement between expectations and first experiences with e-learning. Most students expect the quality of their studies to improve by implementation of e-learning. Students appreciating regularly updated learning materials particularly emphasise the importance of its visualisation. Online tests might be an option for student's self-performance rating.

The aim of the study was to examine the application, design, and analysis characteristics of controlled before-after (CBA) and interrupted time series (ITS) studies and their use in Cochrane reviews. We searched the Cochrane library for reviews including these study designs from May 2012 to March 2015 and purposively selected, where available, two reviews each across 10 prespecified intervention types. We randomly selected two CBA and two ITS studies from each review. Two researchers independently extracted information from the studies and the respective reviews. Sixty-nine reviews considered CBA and ITS studies for inclusion. We analyzed 21 CBA and 16 ITS studies from 11 to 8 reviews, respectively. Cochrane reviews inconsistently defined and labeled CBA and ITS studies. Many studies did not meet the Cochrane definition or the minimum criteria provided by Cochrane Effective Practice and Organisation of Care. The studies present a heterogeneous set of study features and applied a large variety of analyses. While CBA and ITS studies represent important study designs to evaluate the effects of interventions, especially on a population or organizational level, unclear study design features challenge unequivocal classification and appropriate use. We discuss options for more specific definitions and explicit criteria for CBA and ITS studies. Copyright © 2017 Elsevier Inc. All rights reserved.

Impact of design features upon perceived tool usability and safety

Wiker, Steven F.; Seol, Mun-Su

2005-11-01

While injuries from powered hand tools are caused by a number of factors, this study looks specifically at the impact of the tools design features on perceived tool usability and safety. The tools used in this study are circular saws, power drills and power nailers. Sixty-nine males and thirty-two females completed an anonymous web-based questionnaire that provided orthogonal view photographs of the various tools. Subjects or raters provided: 1) description of the respondents or raters, 2) description of the responses from the raters, and 3) analysis of the interrelationships among respondent ratings of tool safety and usability, physical metrics of the tool, and rater demographic information. The results of the study found that safety and usability were dependent materially upon rater history of use and experience, but not upon training in safety and usability, or quality of design features of the tools (e.g., grip diameters, trigger design, guards, etc.). Thus, positive and negative transfer of prior experience with use of powered hand tools is far more important than any expectancy that may be driven by prior safety and usability training, or from the visual cues that are provided by the engineering design of the tool.

Computer-based procedures (CBPs) are expected to improve operator performance in nuclear power plants (NPPs), but they may reduce the openness of interaction between team members and harm teamwork consequently. To support teamwork in the main control room of an NPP, this study proposed a team-level integrated CBP that presents team members' operation status and execution histories to one another. Through a laboratory experiment, we compared the new integrated design and the existing individual CBP design. Sixty participants, randomly divided into twenty teams of three people each, were assigned to the two conditions to perform simulated emergency operating procedures. The results showed that compared with the existing CBP design, the integrated CBP reduced the effort of team communication and improved team transparency. The results suggest that this novel design is effective to optim team process, but its impact on the behavioural outcomes may be moderated by more factors, such as task duration. The study proposed and evaluated a team-level integrated computer-based procedure, which present team members' operation status and execution history to one another. The experimental results show that compared with the traditional procedure design, the integrated design reduces the effort of team communication and improves team transparency.

To use the improved resolution available with 64-slice multidetector computed tomography (MDCT) in vivo to localize the cochlear implant electrode array within the basal turn. Sixty-four-slice MDCT examinations of the temporal bones were retrospectively reviewed in 17 patients. Twenty-three implants were evaluated. Tertiary referral facility. All patients with previous cochlear implantation evaluated at our center between January 2004 and March 2006 were offered a computed tomographic examination as part of the study. In addition, preoperative computed tomographic examinations in patients being evaluated for a second bilateral device were included. Sixty-four-slice MDCT examination of the temporal bones. Localization of the electrode array within the basal turn from multiplanar reconstructions of the cochlea. Twenty-three implants were imaged in 17 patients. We were able to localize the electrode array within the scala tympani within the basal turn in 10 implants. In 3 implants, the electrode array was localized to the scala vestibuli. Migration of the electrode array from scala tympani to scala vestibuli was observed in three implants. Of the 7 implants in which localization of the electrode array was indeterminate, all had disease entities that obscured the definition of the normal cochlear anatomy. Sixty-four-slice MDCT with multiplanar reconstructions of the postoperative cochlea after cochlear implantation allows for accurate localization of the electrode array within the basal turn where normal cochlear anatomy is not obscured by the underlying disease process. Correlating the position of the electrode in the basal turn with surgical technique and implant design could be helpful in improving outcomes.

Effects of organizational scheme and labeling on task performance in product-centered and user-centered retail Web sites.

PubMed

Resnick, Marc L; Sanchez, Julian

2004-01-01

As companies increase the quantity of information they provide through their Web sites, it is critical that content is structured with an appropriate architecture. However, resource constraints often limit the ability of companies to apply all Web design principles completely. This study quantifies the effects of two major information architecture principles in a controlled study that isolates the incremental effects of organizational scheme and labeling on user performance and satisfaction. Sixty participants with a wide range of Internet and on-line shopping experience were recruited to complete a series of shopping tasks on a prototype retail shopping Web site. User-centered labels provided a significant benefit in performance and satisfaction over labels obtained through company-centered methods. User-centered organization did not result in improved performance except when the label quality was poor. Significant interactions suggest specific guidelines for allocating resources in Web site design. Applications of this research include the design of Web sites for any commercial application, particularly E-commerce.

On the Accuracy of Probabilistic Bucking Load Prediction

NASA Technical Reports Server (NTRS)

Arbocz, Johann; Starnes, James H.; Nemeth, Michael P.

2001-01-01

The buckling strength of thin-walled stiffened or unstiffened, metallic or composite shells is of major concern in aeronautical and space applications. The difficulty to predict the behavior of axially compressed thin-walled cylindrical shells continues to worry design engineers as we enter the third millennium. Thanks to extensive research programs in the late sixties and early seventies and the contributions of many eminent scientists, it is known that buckling strength calculations are affected by the uncertainties in the definition of the parameters of the problem such as definition of loads, material properties, geometric variables, edge support conditions, and the accuracy of the engineering models and analysis tools used in the design phase. The NASA design criteria monographs from the late sixties account for these design uncertainties by the use of a lump sum safety factor. This so-called 'empirical knockdown factor gamma' usually results in overly conservative design. Recently new reliability based probabilistic design procedure for buckling critical imperfect shells have been proposed. It essentially consists of a stochastic approach which introduces an improved 'scientific knockdown factor lambda(sub a)', that is not as conservative as the traditional empirical one. In order to incorporate probabilistic methods into a High Fidelity Analysis Approach one must be able to assess the accuracy of the various steps that must be executed to complete a reliability calculation. In the present paper the effect of size of the experimental input sample on the predicted value of the scientific knockdown factor lambda(sub a) calculated by the First-Order, Second-Moment Method is investigated.

2017-01-01

Rehabilitation focuses brain-behavior relationship which highlights interaction between psychological and neurobiological factors for better patient care. There is a missing link in the literature about socio-cognitive aspects of frontal lobe epilepsy. Our objective was to examine prefrontal cortical functioning (PCF) and empathic abilities in patients with frontal lobe epilepsy (FLE). Further, we analyzed whether any relationship between components of dispositional empathy and PCF exists in patients with FLE. The study was designed in an experimental paradigm. Sixty patients with FLE were recruited from Sheikh Zayed and Jinnah hospital, Pakistan. Sixty healthy individuals in response to an advertisement took part in the study as control subjects. Participants completed interpersonal reactivity index. Following they performed clock drawing test and word-color identification task switching experiment. Patients with FLE demonstrated weaker PCF (i.e., cognitive flexibility and executive function) as compared to healthy control subjects. Patients with FLE scored lesser on cognitive empathy as compared to healthy control subjects. On contrary, there was no significant difference between patient and control group on affective empathy. Cognitive not affective empathy was potential predictor of PCF. Cognitive empathy is a significant marker of prefrontal cortical functioning (PCF) in FLE. Higher cognitive empathy would lead to efficient PCF.

No clinical data are available for the new computer-aided design/computer-assisted manufacture (CAD/CAM) material zirconia-reinforced lithium silicate (ZLS) ceramic. This study describes preliminary clinical results for indirect ZLS CAD/CAM restorations after 12 months. Indirect restorations were fabricated, using the CEREC method and intraoral scanning (CEREC Omnicam, CEREC MCXL). Sixty-seven restorations were seated adhesively (baseline). Sixty restorations were evaluated after 12 months (follow-up), using modified FDI criteria. Two groups were established, according to ZLS restorations' post-processing procedure prior to adhesive seating: group I (three-step polishing, n = 32) and group II (fire glazing, n = 28). Statistical analysis was performed with Mann-Whitney U test and Wilcoxon test (P < .05). The success rate of indirect ZLS CAD/CAM restorations after 12 months was 96.7%. Two restorations clinically failed as a result of bulk fracture (failure rate 3.3%). No statistically significant differences were found for baseline and follow-up criteria (Wilcoxon test, P > .05). Statistically significant differences were found for criteria surface gloss for group I and group II (Mann-Whitney U test, P < .05). This study demonstrates ZLS CAD/CAM restorations have a high clinical success rate after 12 months. A longer clinical evaluation period is necessary to draw further conclusions.

The purpose of this study was to assess the websites of American Association of Medical Colleges (AAMC)-member medical schools for the presence of library links. Sixty-one percent (n = 92) of home pages of the 150 member schools of the AAMC contain library links. For the 58 home pages not offering such links, 50 provided a pathway of two or three clicks to a library link. The absence of library links on 39% of AAMC medical school home pages indicates that the designers of those pages did not consider the library to be a primary destination for their visitors.

2008-01-01

This ethnographic study was conducted to determine what homeless people experience during the transition from street life into community housing. Data were gathered through participant observation at a program designed to secure housing and support services for homeless people upon discharge from a psychiatric hospital. Sixty homeless, mentally ill adults were followed from hospital discharge through their first 2 years in community housing. Homeless people interact with health care providers across a cultural divide produced by vast differences in their lived experiences. This cultural distance limits access to the services that these individuals require to achieve residential stability.

Yeom, Hye-A; Fleury, Julie

2014-07-01

There has been limited empirical support for interventions designed to promote physical activity targeting mobility in racially diverse older adults. This study aims to examine the effects of a Motivational Physical Activity Intervention (MPAI) on social resource, behavioral change process, physical activity, and mobility variables in sedentary older Korean Americans. A quasi-experimental, repeated-measure, pre- and post-tests design was used. Sixty-four community-dwelling, sedentary older Korean Americans (n = 33 for MPAI group, n = 31 for Attention Control group) participated in the study. There were significant improvements in social resources, including social support from family and friends; behavioral change process variables, including self-efficacy; motivational appraisal; and self-regulation for physical activity. There were significant intervention effects on physical activity, walking endurance, and flexibility. The MPAI is supported as improving mobility and physical activity, as well as increasing motivation for physical activity in older Korean Americans. © The Author(s) 2013.

2015-12-01

This case study provides a high-level overview of the human-centered design (HCD) or "design thinking" process and its relevance to public health. The Best Babies Zone (BBZ) initiative is a multi-year project aimed at reducing inequities in infant mortality rates. In 2012, BBZ launched pilot programs in three US cities: Cincinnati, Ohio; New Orleans, Louisiana; and Oakland, California. The Alameda County Public Health Department (ACPHD), the lead for the Oakland BBZ site, identified HCD as a promising approach for addressing the social and economic conditions that are important drivers of health inequities. HCD is a process for creating innovative products, services, and strategies that prioritizes the needs of the intended population. ACPHD partnered with the Gobee Group (a social innovation design consultancy) to develop the Design Sprint. The Design Sprint was a 12-week pilot in which 14 professionals from nine organizations used the HCD process to develop concepts for stimulating a vibrant local economy in the Oakland Best Babies Zone. Thirty- to sixty-minute semi-structured interviews were conducted with all 14 individuals involved in the Design Sprint. With the exception of one interview, the interviews were audio-recorded, transcribed, and inductively coded to identify themes. Our experience suggests that HCD can: enhance community engagement; expedite the timeframe for challenge identification, program design, and implementation; and create innovative programs that address complex challenges.

Gould, Douglas J.; Terrell, Mark A.; Fleming, Jo

2015-01-01

This usability study evaluated users’ perceptions of a multimedia prototype for a new e-learning tool: Anatomy of the Central Nervous System: A Multimedia Course. Usability testing is a collection of formative evaluation methods that inform the developmental design of e-learning tools to maximize user acceptance, satisfaction, and adoption. Sixty-two study participants piloted the prototype and completed a usability questionnaire designed to measure two usability properties: program need and program applicability. Statistical analyses were used to test the hypothesis that the multimedia prototype was well designed and highly usable, it was perceived as: 1) highly needed across a spectrum of educational contexts, 2) highly applicable in supporting the pedagogical processes of teaching and learning neuroanatomy, and 3) was highly usable by all types of users. Three independent variables represented user differences: level of expertise (faculty vs. student), age, and gender. Analysis of the results supports the research hypotheses that the prototype was designed well for different types of users in various educational contexts and for supporting the pedagogy of neuroanatomy. In addition, the results suggest that the multimedia program will be most useful as a neuroanatomy review tool for health-professions students preparing for licensing or board exams. This study demonstrates the importance of integrating quality properties of usability with principles of human learning during the instructional design process for multimedia products. PMID:19177405

Short dental implants in patients with oral lichen planus: a long-term follow-up.

PubMed

Anitua, E; Piñas, L; Escuer-Artero, V; Fernández, R S; Alkhraisat, M H

2018-04-01

Oral lichen planus is associated with the Koebner phenomenon, and trauma may exacerbate oral lesions. Short dental implants, as alternatives to bony augmentation, would reduce the number of interventions and their morbidity. However, we know of no studies that have analysed the long-term outcomes of short implants in patients with oral lichen planus. We have therefore designed a retrospective study of such patients treated with short implants (≤8.5mm long), with survival of implants as the main outcome. The secondary outcomes were marginal bone loss and the development of complications. We calculated the implants' survival and compared the outcomes statistically between erosive and reticular oral lichen planus. Sixty-six short implants were placed in 23 patients with a mean (SD) age of 58 (7) years. The mean (SD) peri-implant bone loss was 0.96 (0.89) mm mesially and 0.99 (1.1) mm distally. Sixty-five of the 66 implants survived with a mean (SD) follow-up of 68 (32) months, and there were no significant differences between erosive and reticular disease. Stable long-term outcomes can be expected for short implants placed in patients with oral lichen planus, and graftless rehabilitation of missing teeth could be possible in these patients if short implants were used.

Hearing aid user guides: suitability for older adults.

PubMed

Caposecco, Andrea; Hickson, Louise; Meyer, Carly

2014-02-01

The aim of this study was to analyse the content, design, and readability of printed hearing aid user guides to determine their suitability for older adults, who are the main users of hearing aids. Hearing aid user guides were assessed using four readability formulae and a standardized tool to assess content and design (SAM - Suitability Assessment of Materials). A sample of 36 hearing aid user guides (four user guides from nine different hearing aid manufacturers) were analysed. Sixty nine percent of user guides were rated 'not suitable' and 31% were rated 'adequate' for their suitability. Many scored poorly for scope, vocabulary, aspects of layout and typography, and learning stimulation and motivation. The mean reading grade level for all user guides was grade 9.6 which is too high for older adults. The content, design, and readability of hearing aid user guides are not optimal for older adults and thus may serve as a barrier to successful hearing aid outcomes for this population.

As a continuous effort to discover new potential anti-inflammatory agents, we systematically designed and synthesized sixty-one 2-benzylidene-1-indanone derivatives with structural modification of chalcone, and evaluated their inhibitory activity on LPS-stimulated ROS production in RAW 264.7 macrophages. Systematic structure-activity relationship study revealed that hydroxyl group in C-5, C-6, or C-7 position of indanone moiety, and ortho-, meta-, or para-fluorine, trifluoromethyl, trifluoromethoxy, and bromine functionalities in phenyl ring are important for inhibition of ROS production in LPS-stimulated RAW 264.7 macrophages. Among all the tested compounds, 6-hydroxy-2-(2-(trifluoromethoxy) benzylidene)-2,3-dihydro-1H-inden-1-one (compound 44) showed the strongest inhibitory activity of ROS production. Further studies on the mode of action revealed that compound 44 potently suppressed LPS-stimulated ROS production via modulation of NADPH oxidase. The findings of this work could be useful to design 2-benzylidene-indanone based lead compounds as novel anti-inflammatory agents. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Objective. To evaluate the feasibility of an online training module, Certified Smoking Cessation Service Provider (CSCSP), developed for practicing pharmacists to equip pharmacy students with knowledge necessary for smoking cessation counseling and to assess the changes in student knowledge and skills regarding smoking cessation following training. Design. Sixty third-year and 80 fourth-year pharmacy undergraduates (N=140) were given access to an online module, the main intervention in the study. Two linkable questionnaires were administered to assess students’ preintervention and postintervention knowledge. For the third-year students, an additional role-play training component was incorporated, and student skills were assessed during week 14 with an Objective Structured Clinical Examination (OSCE). Assessment. Preintervention and postintervention knowledge assessments were completed by 130 (92.8%) students. Sixty-six students scored above 50% for the knowledge component postintervention, compared to 13 at preintervention, demonstrating significant improvement (x2(1, N=130)=32, p=0.003). All third-year students completed the intervention, and 66.7% were able to counsel excellently for smoking cessation, scoring more than 80%. Conclusion. The CSCSP online module developed for practicing professionals was found suitable for equipping pharmacy undergraduates with knowledge on smoking cessation topics. The module, along with role-play training, also equipped students with knowledge and skills to provide smoking cessation counseling. PMID:26246620

Our objective was to document the pattern of mobile phone usage by medical staff in a hospital setting, and to explore any perceived benefits (such as improved communications) associated with mobile phones. This cross-sectional survey was conducted in Waterford Regional Hospital, Ireland, where bleep is the official system of communication. All non-consultant hospital doctors, of medical disciplines only, were asked to participate. The questionnaire was designed to explore the pattern and different aspects of mobile phone usage. At the time of study, there were sixty medical junior doctors, and the response rate was 100 percent. All participants used mobile phones while at work, and also for hospital-related work. For 98.3 percent the mobile phone was their main mode of communication while in the hospital. Sixty-two percent (n = 37) made 6-10 calls daily purely for work-related business, and this comprised of ≥ 80 percent of their daily usage of mobile phones. For 98 percent of participants, most phone calls were work-related. Regarding reasons for using mobile phones, all reported that using mobile phone is quicker for communication. Mobile phone usage is very common among the medical personnel, and this is regarded as a more efficient means of communication for mobile staff than the hospital paging system.

The aim of this study was to analyze the influence of melting and casting procedures and the cervical finish line design on the marginal fit of nickel-chromium-titanium alloy crowns. Sixty standardized specimens were prepared to receive metal-ceramic crowns and were divided into two groups according to the cervical finish line: chamfer or rounded shoulder. Three melting and casting procedures were analyzed: (1) induction-centrifuge (IC), (2) gas oxygen torch-centrifuge (TC), and (3) induction-vacuum/pressure (IP). The marginal fit was measured with an image analysis system. Significant differences (P =.005) were observed among the groups, with TC showing the lowest discrepancies (45.87 μm). No significant differences were observed between the two finish lines. The accuracy of fit achieved for the groups analyzed may be regarded as within the range of clinical acceptance.

We report the first non-designer study of the Unix uncemented unicompartmental knee prosthesis. Eighty-five consecutive UKRs were carried out with sixty-five available for follow-up. Oxford Knee Scores, WOMAC questionnaire and radiological assessment were completed. The mean Oxford Knee Score was thirty-eight and WOMAC Score was twenty. Overall Kaplan Meier survival estimate is 76% (95% confidence interval 60%-97%) at 12years and 88% (95% confidence interval 76-100%) with aseptic loosening as the endpoint. Radiographic assessment showed lysis in the tibia in 6% of patients with no lysis evident around the central fin. Survivorship is comparable to other published series of UKRs. We suggest the central fin design is key to dissipating large forces throughout the proximal tibia, resulting in low levels of tibial loosening. Level of evidence IV. Copyright © 2012 Elsevier B.V.

The optical design of the wide field of view refractive camera, 34 degrees diagonal field, for the TESS payload is described. This fast f/1.4 cryogenic camera, operating at -75 C, has no vignetting for maximum light gathering within the size and weight constraints. Four of these cameras capture full frames of star images for photometric searches of planet crossings. The optical design evolution, from the initial Petzval design, took advantage of Forbes aspheres to develop a hybrid design form. This maximized the correction from the two aspherics resulting in a reduction of average spot size by sixty percent in the final design. An external long wavelength pass filter was replaced by an internal filter coating on a lens to save weight, and has been fabricated to meet the specifications. The stray light requirements were met by an extended lens hood baffle design, giving the necessary off-axis attenuation.

The current study examined the mediating role of hopelessness on the relationship between psychological vulnerability and subjective happiness. It was anticipated that hopelessness may act as a mediator in the relationship between psychological vulnerability and subjective happiness. Two hundred sixty-nine (150 women and 119 men) university students completed the Psychological Vulnerability Scale, the Subjective Happiness Scale and the Beck Hopelessness Scale. Data have been collected in the 2013-2014 academic year. The present study was designed as a cross-sectional study. Correlational results indicated that psychological vulnerability and hopelessness were significantly negatively associated with subjective happiness. Results using structural equation modelling showed that hopelessness fully mediated the relationship between psychological vulnerability and subjective happiness. Implications for future research and limitations of the present study are discussed. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

People living with HIV /AIDS (PLWHA) and HIV/AIDS associated oral lesions; a study in Malaysia

PubMed Central

2012-01-01

Background The continuous increase in number of people living with HIV/AIDS (PLWHA) represents a serious health and economic burden. HIV positive individuals with oral lesions have significantly lower oral health-related quality of life than HIV positive individuals without oral lesions. The objective of this study was to assess the knowledge, attitude and practices (KAP) within a cohort of HIV/AIDS positive patients towards HIV/AIDS associated oral lesions. Methods Two hundred seventy patients attending a national referral hospital of infectious disease in Malaysia were recruited for the study. The study involved the administration of a validated interview-based questionnaire designed to elicit knowledge, attitude and practices of these patients towards HIV associated oral lesions. The last part of the questionnaire assessed the training provided to the patients in relation to the oral lesions associated with the disease and the effectiveness of this training. Data analysis was carried out using SPSS version 18. Results Thirty seven percent of patients were reported as knowledgeable, while sixty four percent reported to have positive attitude towards the care of oral hygiene. Sixty six percent of the patients reported that they would seek professional care when experiencing oral lesion. Training was reported effective for 93% patients. Conclusions Patients were non-knowledgeable in relation to oral manifestations of the disease and one third of the participating patients showed negative attitudes towards oral health care and reported various measures to manage oral lesions rather than seeking professional care. Developing effective educational methodologies can empower patients with knowledge that may translate to positive attitudes and practices. PMID:23043358

Van der Velden, Alexander J. M.

1987-01-01

A conceptual Oblique Flying Wing Supersonic Transport Aircraft (OFW, or surfplane because of its shape) was first proposed in 1957. It was reintroduced in 1987 in view of the emerging technology of artificial stabilization. This paper is based on the performance and economics study of an M2 B747-100B replacement aircraft. In order to make a fair comparison of this configuration with the B747, an end-sixties structural technology level is assumed. It is shown that a modern stability and control system can balance the aircraft and smooth out gusts, and that the OFW configuration equals or outperforms the B747 in speed, economy and comfort.

This study was designed to examine plasma concentrations of BNP and its correlations to the perioperative course in patients' cardiopulmonary bypass (CPB). Sixty-five patients with coronary artery disease (CAD) undergoing CPB were examined. Pre, intra and postoperative BNP values and hemodynamic parameters were measured. The BNP peak correlated neither with any hemodynamic parameters, with the duration of aortic cross-clamping (AXCL), of the operation or with CBP-time, nor with the use of catecholamines. BNP values were significantly higher with the perioperative use of aprotinin. These results confirm that the metabolism and biological activity of BNP may differ following CPB. An additional reason for increased postoperative BNP values might be the use of aprotinin.

Explore-create-share study: An evaluation of teachers as curriculum innovators in engineering education

NASA Astrophysics Data System (ADS)

Berry, Ayora

The purpose of this study was to investigate the effects of a curriculum design-based (CDB) professional development model on K-12 teachers' capacity to integrate engineering education in the classroom. This teacher professional development approach differs from other training programs where teachers learn how to use a standard curriculum and adopt it in their classrooms. In a CDB professional development model teachers actively design lessons, student resources, and assessments for their classroom instruction. In other science, technology, engineering and mathematics (STEM) disciplines, CDB professional development has been reported to (a) position teachers as architects of change, (b) provide a professional learning vehicle for educators to reflect on instructional practices and develop content knowledge, (c) inspire a sense of ownership in curriculum decision-making among teachers, and (d) use an instructional approach that is coherent with teachers' interests and professional goals. The CDB professional development program in this study used the Explore-Create-Share (ECS) framework as an instructional model to support teacher-led curriculum design and implementation. To evaluate the impact of the CDB professional development and associated ECS instructional model, three research studies were conducted. In each study, the participants completed a six-month CDB professional development program, the PTC STEM Certificate Program, that included sixty-two instructional contact hours. Participants learned about industry and education engineering concepts, tested engineering curricula, collaborated with K-12 educators and industry professionals, and developed project-based engineering curricula using the ECS framework. The first study evaluated the impact of the CDB professional development program on teachers' engineering knowledge, self-efficacy in designing engineering curriculum, and instructional practice in developing project-based engineering units. The study included twenty-six teachers and data was collected pre-, mid-, and post-program using teacher surveys and a curriculum analysis instrument. The second study evaluated teachers' perceptions of the ECS model as a curriculum authoring tool and the quality of the curriculum units they developed. The study included sixty-two participants and data was collected post-program using teacher surveys and a curriculum analysis instrument. The third study evaluated teachers' experiences implementing ECS units in the classroom with a focus on identifying the benefits, challenges and solutions associated with project-based engineering in the classroom. The study included thirty-one participants and data was collected using an open-ended survey instrument after teachers completed implementation of the ECS curriculum unit. Results of these three studies indicate that teachers can be prepared to integrate engineering in the classroom using a CDB professional development model. Teachers reported an increase in engineering content knowledge, improved their self-efficacy in curriculum planning, and developed high quality instructional units that were aligned to engineering design practices and STEM educational standards. The ECS instructional model was acknowledged as a valuable tool for developing and implementing engineering education in the classroom. Teachers reported that ECS curriculum design aligned with their teaching goals, provided a framework to integrate engineering with other subject-area concepts, and incorporated innovative teaching strategies. After implementing ECS units in the classroom, teachers reported that the ECS model engaged students in engineering design challenges that were situated in a real world context and required the application of interdisciplinary content knowledge and skills. Teachers also reported a number of challenges related to scheduling, content alignment, and access to resources. In the face of these obstacles, teachers presented a number of solutions that included optimization of one's teaching practice, being resource savvy, and adopting a growth mindset.

The results are reported of a preliminary feasibility screening study for providing long-term solutions to the problems of handling and managing radioactive wastes by extraterrestrial transportation of the wastes. Matrix materials and containers are discussed along with payloads, costs, and destinations for candidate space vehicles. The conclusions reached are: (1) Matrix material such as spray melt can be used without exceeding temperature limits of the matrix. (2) The cost in mills per kw hr electric, of space disposal of fission products is 4, 5, and 28 mills per kw hr for earth escape, solar orbit, and solar escape, respectively. (3) A major factor effecting cost is the earth storage time. Based on a normal operating condition design for solar escape, a storage time of more than sixty years is required to make the space disposal charge less than 10% of the bus-bar electric cost. (4) Based on a 10 year earth storage without further processing, the number of shuttle launches required would exceed one per day.

This qualitative design study addressed the enhancement of nursing assessment skills through the use of Visual Thinking Strategies and reflection. This study advances understanding of the use of Visual Thinking Strategies and reflection as ways to explore new methods of thinking and observing patient situations relating to health care. Sixty nursing students in a licensed practical nursing program made up the sample of participants who attended an art gallery as part of a class assignment. Participants replied to a survey of interest for participation at the art gallery. Participants reviewed artwork at the gallery and shared observations with the larger group during a post-conference session in a gathering area of the museum at the end of the visit. A reflective exercise on the art gallery experience exhibited further thoughts about the art gallery experience and demonstrated the connections made to clinical practice by the student. The findings of this study support the use of Visual Thinking Strategies and reflection as effective teaching and learning tools for enhancing nursing skills. Copyright © 2017 Elsevier Ltd.

The present study aimed to assess the safety of gluten-free bakery products for consumption by coeliac patients. Design/setting In the current exploratory cross-sectional quantitative study, a total of 130 samples were collected from twenty-five bakeries in Brasilia (Brazil). For the quantification of gluten, an ELISA was used. The threshold of 20 ppm gluten was considered as the safe upper limit for gluten-free food, as proposed in the Codex Alimentarius. The results revealed a total of 21·5 % of contamination among the bakery products sampled. Sixty-four per cent of the bakeries sold at least one contaminated product in our sample. These findings represent a risk for coeliac patients since the ingestion of gluten traces may be sufficient to adversely impact on their health.

Participatory Action Research on Help-Seeking Behaviors of Self-Defined Ritual Abuse Survivors: A Brief Report.

PubMed

Matthew, Laurie; Barron, Ian G

2015-01-01

The existence of ritual abuse is the subject of much debate. Ritual abuse survivor perceptions of seeking help have not been explored, and studies have yet to utilize self-defined survivors as collaborative researchers. This study addresses both issues. Participatory action research was utilized to design a survey and semistructured interview to investigate ritual abuse survivor experience of seeking help. Sixty-eight participants completed the survey, and 22 were interviewed. A group approach to thematic analysis aided validity and reliability. Participants reported experiencing disbelief and a lack of ritual abuse awareness and help from support services. In contrast, participatory action research was reported by participants as educative and emancipatory. Future research should explore the benefits of participatory action research for survivors of different forms of oppression.

This study was designed to assess the gross morphometric studies of the tongue, hard palate and buccal cavity of the fruit bat (Eidolon helvum). Sixty bats of both sexes were used for this study. The tongue was excised, and the weight and various linear measurements were determined. Linear measurements were also determined on the hard palate. The gross distribution of the lingual papillae was observed to be the same in both sexes; values obtained for the weight and length of the tongue were higher in the females, although no statistically significant differences were observed (P > 0.05). The number of ridges on the hard palate displayed sexual dimorphism. Results obtained from this study may find application in the field of comparative and clinical anatomy of wildlife and also in feeding physiology. © 2014 Blackwell Verlag GmbH.

Worrying Thoughts Limit Working Memory Capacity in Math Anxiety

2016-01-01

Sixty-one high-math-anxious persons and sixty-one low-math-anxious persons completed a modified working memory capacity task, designed to measure working memory capacity under a dysfunctional math-related context and working memory capacity under a valence-neutral context. Participants were required to perform simple tasks with emotionally benign material (i.e., lists of letters) over short intervals while simultaneously reading and making judgments about sentences describing dysfunctional math-related thoughts or sentences describing emotionally-neutral facts about the world. Working memory capacity for letters under the dysfunctional math-related context, relative to working memory capacity performance under the valence-neutral context, was poorer overall in the high-math-anxious group compared with the low-math-anxious group. The findings show a particular difficulty employing working memory in math-related contexts in high-math-anxious participants. Theories that can provide reasonable interpretations for these findings and interventions that can reduce anxiety-induced worrying intrusive thoughts or improve working memory capacity for math anxiety are discussed.

Domeño, Celia; Aznar, Margarita; Nerín, Cristina; Isella, Francesca; Fedeli, Mauro; Bosetti, Osvaldo

2017-07-01

Printing inks are commonly used in multilayer plastics materials used for food packaging, and compounds present in inks can migrate to the food either by diffusion through the multilayers or because of set-off phenomena. To avoid this problem, the right design of the packaging is crucial. This paper studies the safety by design of multilayer materials. First, the migration from four different multilayers manufactured using polyethylene terephthalate (PET), aluminium (Al) and polyethylene (PE) was determined. The structural differences among materials such as the presence of inks or lacquer coatings as well as the differences in layers position allowed the study of a safety-by-design approach. Sixty-nine different compounds were detected and identified; 49 of them were not included in the positive list of Regulation EU/10/2011 or in Swiss legislation and 15 belong to Cramer class III, which means that they have a theoretical high toxicity. Some of the compounds related to ink composition were pyrene, a compound commercially used to make dyes and dye precursors and the antioxidant Irganox 1300. The application of external lacquers decreased the concentration of some migrants but also brought the potential for new migrants coming from its composition. A final risk assessment of the material allowed evaluating food safety for different food simulants and confirm it.

An approach to studying scale for students in higher education: a Rasch measurement model analysis.

Waugh, R F; Hii, T K; Islam, A

2000-01-01

A questionnaire comprising 80 self-report items was designed to measure student Approaches to Studying in a higher education context. The items were conceptualized and designed from five learning orientations: a Deep Approach, a Surface Approach, a Strategic Approach, Clarity of Direction and Academic Self-Confidence, to include 40 attitude items and 40 corresponding behavior items. The study aimed to create a scale and investigate its psychometric properties using a Rasch measurement model. The convenience sample consisted of 350 students at an Australian university in 1998. The analysis supported the conceptual structure of the Scale as involving studying attitudes and behaviors towards five orientations to learning. Attitudes are mostly easier than behaviors, in line with the theory. Sixty-eight items fit the model and have good psychometric properties. The proportion of observed variance considered true is 92% and the Scale is well-targeted against the students. Some harder items are needed to improve the targeting and some further testing work needs to be done on the Surface Approach. In the Surface Approach and Clarity of Direction in Studying, attitudes make a lesser contribution than behaviors to the variable, Approaches to Studying.

2018-02-01

A proton-proton collider at center-of-mass energy of more than 70 TeV is the second stage of the CEPC-SPPC program. As proposed, the SPPC injector chain will use a 1.2 GeV p-Linac and three synchrotrons of 10 GeV p-RCS, 180 GeV MSS and 2.1 TeV SS. Peking University is responsible for the preliminary conceptual design of the room temperature part of SPPC p-Linac. This paper is focusing on the beam dynamics studies performed with respect to the 325 MHz RFQ. As the first accelerator structure after the ion source and the front-end of the whole SPPC, RFQ plays an important role in the beam initial transverse focusing and longitudinal bunching. Based on the New Four Section Procedure strategy, as well as the matched and Equipartitioning design method, a 3 MeV RFQ designed by Parmteq code will be introduced. The cavity length of RFQ is 3.6 m and the transmission efficiency is 98%. In this design scheme, the 40 mA proton beam from the 50 keV ion source is accelerated to 3 MeV in 3.8 m length, which achieves a sixty times energy gain. The results of the analyses show that the RFQ design is reliable and meets all the SPPC p-Linac requirements well.

Understanding reliance on automation: effects of error type, error distribution, age and experience

2015-01-01

An obstacle detection task supported by “imperfect” automation was used with the goal of understanding the effects of automation error types and age on automation reliance. Sixty younger and sixty older adults interacted with a multi-task simulation of an agricultural vehicle (i.e. a virtual harvesting combine). The simulator included an obstacle detection task and a fully manual tracking task. A micro-level analysis provided insight into the way reliance patterns change over time. The results indicated that there are distinct patterns of reliance that develop as a function of error type. A prevalence of automation false alarms led participants to under-rely on the automation during alarm states while over relying on it during non-alarms states. Conversely, a prevalence of automation misses led participants to over-rely on automated alarms and under-rely on the automation during non-alarm states. Older adults adjusted their behavior according to the characteristics of the automation similarly to younger adults, although it took them longer to do so. The results of this study suggest the relationship between automation reliability and reliance depends on the prevalence of specific errors and on the state of the system. Understanding the effects of automation detection criterion settings on human-automation interaction can help designers of automated systems make predictions about human behavior and system performance as a function of the characteristics of the automation.

To compare patients with traumatic brain injury (TBI) with controls on sub-types of aggression and explore the role of social desirability. Quasi-experimental, matched-participants design. Sixty-nine participants were included in the study. The sample comprised a TBI group (n = 24), a spinal cord injury (SCI) group (n = 21) and an uninjured (UI) group of matched healthy volunteers (n = 24). Participants were given self-report measures of aggression, social desirability and impulsivity. Sixty-one independent 'other-raters' were nominated, who rated participant pre-morbid and post-morbid aggression. Using standardized norms, 25-39% of participants with TBI were classified as high average-very high on anger and 35-38% as high average-very high on verbal aggression. Other-raters rated participants with TBI as significantly higher on verbal aggression than SCI and UI participants. There were no differences between the groups on physical aggression. The TBI group also had higher levels of impulsivity than SCI and UI groups. Social desirability was a highly significant predictor of self-reported aggression for the entire sample. Impulsive verbal aggression and anger are the principal aggressive traits after brain injury. Physical aggression may present in extreme cases after TBI, but appears less prominent overall in this population. Social desirability, previously overlooked in research examining TBI aggression, emerged as an influential variable that should be considered in future TBI research.

An obstacle detection task supported by "imperfect" automation was used with the goal of understanding the effects of automation error types and age on automation reliance. Sixty younger and sixty older adults interacted with a multi-task simulation of an agricultural vehicle (i.e. a virtual harvesting combine). The simulator included an obstacle detection task and a fully manual tracking task. A micro-level analysis provided insight into the way reliance patterns change over time. The results indicated that there are distinct patterns of reliance that develop as a function of error type. A prevalence of automation false alarms led participants to under-rely on the automation during alarm states while over relying on it during non-alarms states. Conversely, a prevalence of automation misses led participants to over-rely on automated alarms and under-rely on the automation during non-alarm states. Older adults adjusted their behavior according to the characteristics of the automation similarly to younger adults, although it took them longer to do so. The results of this study suggest the relationship between automation reliability and reliance depends on the prevalence of specific errors and on the state of the system. Understanding the effects of automation detection criterion settings on human-automation interaction can help designers of automated systems make predictions about human behavior and system performance as a function of the characteristics of the automation.

We developed an integrative day care clinic program for cancer patients focusing on mind-body techniques and health-promoting lifestyle modification (7-hour once-per-week group sessions over 12 weeks). A cohort study design with a waiting group was implemented. Outcome parameters were assessed at the beginning, at the end of the active program, and at a 6-month follow-up. Patients waiting >4 and <12 weeks before treatment start were allocated to the waiting group and additionally assessed at the start of their day care program. Outcome measures included quality of life (FACT-G, FACT-B/C, WHO-5), fatigue (FACIT-F), depression/anxiety (HADS), and mood states (ASTS). A per protocol analysis using mixed linear models was performed. One hundred patients were screened on-site for eligibility. Eighty-six cancer survivors (83% female; mean age 53.7 ± 9.7 years; 49% breast cancer) were included into the study. Sixty-two patients were allocated to the intervention group and 24 patients, to the waiting group (mean waiting time 5 ± 1 weeks). Sixty-six data sets were included in the final analysis. Significant improvements were observed in favor of the intervention group after 12 weeks compared with the waiting group at the end of the waiting period for quality of life, anxiety/depression, and fatigue. Results from the 6-month follow-up for the whole study population showed lasting improvement of quality of life. The program can be considered as an effective means to improve quality of life, fatigue, and mental health of cancer patients. Moreover, it appears to have a sustainable effect, which has to be proved in randomized trials. Copyright © 2017 John Wiley & Sons, Ltd.

We carried out a prospective study of an Internet-based remote counselling service. A total of 15456 Internet users visited the Website over eight years. From these, 1500 users were randomly selected for analysis. Medical counselling had been granted to 901 of the people requesting it (60%). One hundred and sixty-four physicians formed project groups to process the requests and responded using email. The distribution of patients using the service was similar to the availability of the Internet: 78% were from the European Union, North America and Australia. Sixty-seven per cent of the patients lived in urban areas and the remainder were residents of remote rural areas with limited local medical coverage. Sixty-five per cent of the requests were about problems of internal medicine and 30% of the requests concerned surgical issues. The remaining 5% of the patients sought information about recent developments, such molecular medicine or aviation medicine. During the project, our portal became inaccessible five times, and counselling was not possible on 44 days. There was no hacking of the Website. Internet-based medical counselling is a helpful addition to conventional practice.

In this paper, we report the progress in developing a silica-aerogel-based cosmic dust capture panel for use in the Tanpopo experiment on the International Space Station (ISS). Previous studies revealed that ultralow-density silica aerogel tiles, comprising two layers with densities of 0.01 and 0.03 g/cm(3) developed using our production technique, were suitable for achieving the scientific objectives of the astrobiological mission. A special density configuration (i.e., box framing) aerogel with a holder was designed to construct the capture panels. Qualification tests for an engineering model of the capture panel as an instrument aboard the ISS were successful. Sixty box-framing aerogel tiles were manufactured in a contamination-controlled environment.

To compare the immediate implant success rates between sites with chronic apical lesions and healthy sites in the same patients 1 year postdelayed loading. One hundred sixty-eight immediate implants were placed in sixty patients at upper incisor, canine, and premolar sites. A split-mouth design was used, placing a minimum of two implants, one in a fresh socket associated with chronic periapical disease, the average lesion size was larger than 4 mm and less than 8 mm (test group), and the other(s) in a healthy fresh socket (control group). Implant survival rate at 1 year postloading delayed was compared between the groups. The implant survival rate was 98.2% for the total sample (n = 168); out of the three implants lost, two were from the test group, and one was from the control group (in the same patient as one of the former). Among the surviving implants, five were also considered failures due to excessive bone loss (n = 3) and also because of the recurrence of the periapical lesions (n = 2). Survival rates were significantly lower in the test than control sites at 12 months postloading. Implant survival rates were significantly lower after the immediate implantation in postextraction sockets associated with chronic periapical disease (90.8%) than in healthy postextraction sockets (98.1%). © 2015 Wiley Periodicals, Inc.

The aim of this study was to develop, implement, and evaluate a theory-based intervention designed to promote increased health empowerment for marriage migrant women in Taiwan. The rapid increase of international marriage immigration through matchmaking agencies has received great attention recently because of its impact on social and public health issues in the receiving countries. A participatory action research (PAR) and in-depth interviews were adopted. Sixty-eight women participated in this study. Eight workshops of the health empowerment project were completed. Through a PAR-based project, participants received positive outcomes. Four outcome themes were identified: (a) increasing health literacy, (b) facilitating capacity to build social networks, (c) enhancing sense of self-worth, and (d) building psychological resilience. PAR was a helpful strategy that enabled disadvantaged migrant women to increase their health literacy, psychological and social health, and well-being. The findings can be referenced by the government in making health-promoting policies for Southeast Asian immigrant women to increase their well-being. Community health nurses can apply PAR strategies to plan and design health promotion intervention for disadvantaged migrant women. © 2014 Sigma Theta Tau International.

The prevention of overweight and obesity during infancy is a highly relevant public health topic given the significant impact of childhood obesity on acute and chronic diseases, general health, and well-being in later stages of life. Apart from the family setting, daycare facilities (DFs) represent a key setting for health promotion among children under the age of six years. "JolinchenKids - Fit and Healthy in Daycare" is a multi-component program promoting physical activity (PA), healthy eating, and mental well-being in 3- to 6-year-old preschoolers at DFs, originally designed by the German health insurance AOK. To evaluate program effectiveness, a cluster-controlled trial involving 68 DFs is currently conducted. The objective of this article is to describe the background, study design, and aims of this trial. Sixty-eight DFs across Germany will be recruited to take part in the study, half of them serving as intervention DFs and half of them as delayed intervention control DFs (which receive the program upon completion of the study). At each DF, height, weight, and body composition, as well as motor skills, will be assessed in twenty 3- to 6-year-old children. Children's eating and PA habits, and mental well-being will be assessed via parental questionnaires. A subsample of children (i.e., at 24 DFs which are randomly selected within a geographic region) will be asked to wear accelerometers at their wrists to objectively measure PA over the course of seven days. To compare changes in body composition, motor skills, eating and PA habits, and mental well-being of children at intervention DFs with those observed among children at delayed intervention control DFs over one year, all measurements will take place at baseline and twelve months after the launch of the program at all DFs. This study investigates the influence of a health promotion program in the daycare setting on various outcomes, including body composition and objectively measured PA, in a nationwide sample of 3- to 6-year-old preschoolers. This study will provide evidence regarding the effectiveness of a multi-component program for health promotion in this setting and may provide insights into new strategies for preventing obesity in early life.

2001-01-01

This randomized, placebo-controlled, double-blind study was designed to investigate the efficacy and tolerability of a new agent for the treatment of hair loss, based on a marine protein, minerals and vitamins. Sixty subjects with hair loss of different aetiologies participated in the 6-month blinded phase of the study. Objective assessments indicated that the treatment was effective and subjective assessments showed a statistically significant positive effect of treatment. Exposure to the active preparation for a further 6 months in an open phase indicated a further improvement in hair growth. Exposure of the patients previously treated with placebo to the active preparation for 12 months gave similar results. Tolerability was good and no side-effects were reported. The product investigated may provide an alternative to pharmacotherapy for the treatment of hair-loss problems in individuals with androgenic alopecia.

The purpose of this study was to evaluate the impact of a brief, interactive multimedia tutorial designed to prepare dentists to recognize and respond to domestic violence. The authors randomly assigned dentists and dental students to one of three groups: a control group or one of two experimental groups in a modified Solomon four-group design. One hundred sixty-one dental students and 13 dentists completed the multimedia tutorial. At the posttest, subjects in both experimental groups demonstrated significantly better scores than did subjects in the control group on most items. The two experimental groups (pretest and posttest, posttest only) did not differ significantly from each other. An engaging, interactive tutorial presenting a simplified model for ways in which dental professionals can recognize and respond to domestic violence significantly improved dental students' knowledge of, and attitudes toward, the topic. Clinicians may improve the care they provide to patients by accessing this brief tutorial and following the lessons contained in it.

To examine the influence of two different neck designs on facial bone crest dimensions in esthetic single implant sites after a 5-to-9-year follow-up analyzed by cone beam computed tomography (CBCT). Sixty-one patients with an implant-borne single crown following early implant placement in the esthetic zone were enrolled. The test group consisted of a bone level (BL) neck design exhibiting a hydrophilic micro-rough surface combined with a platform-switching interface (PS) (n = 20). The control group comprised a soft tissue level (STL) neck design exhibiting a hydrophobic machined surface with a matching butt-joint interface (n = 41). Standardized clinical, radiologic, and esthetic parameters were applied. The facial bone crest dimensions were assessed by CBCT. Soft tissue parameters and pink esthetic scores yielded no significant differences between the two designs. Major differences were only observed at the implant shoulder level. The height of the facial bone crest for the BL design was located 0.2 mm above the implant shoulder level, whereas for the STL design, its location was 1.6 mm below. The width of the peri-implant saucer-like bone defect was reduced by 40% for the BL implant design. No differences were observed 2 mm below the shoulder level. The results of this comparative study suggest better crestal bone stability on the facial aspect of single implant sites in the esthetic zone for a BL design with a platform-switching concept when compared with STL implants with a butt-joint interface. © 2015 John Wiley & Sons A/S.

With global population aging, great business opportunities are driven by the various needs that the elderly face in everyday living. Internet development makes information spread faster, also allows elderly and their caregivers to more easily access information and actively participate in value co-creation in the services. This study aims to investigate the designs of value co-creation by the supply and demand sides of the senior industry. This study investigated senior industry in Taiwan and analyzed bussiness models of 33 selected successful senior enterprises in 2013. We adopted series field observation, reviews of documentations, analysis of meeting records and in-depth interviews with 65 CEOs and managers. Thirty-three quality enterprises in senior industry. Sixty-five CEOs and managers in 33 senior enterprises. None. Value co-creation design, value co-creating process. We constructed a conceptual model that comprehensively describes essential aspects of value co-creation and categorized the value co-creation designs into four types applying for different business models: (i) interaction in experience spaces co-creation design, (ii) on-site interacting co-creation design, (iii) social networking platform co-creation design and (iv) empowering customers co-creation design. Through value co-creation platform design, the senior enterprises have converted the originally passive roles of the elderly and caregivers into active participants in the value co-creation process. The new paradigm of value co-creation designs not only promote innovative development during the interactive process, lead enterprises reveal and meet customers' needs but also increase markets and profits. © The Author 2016.

Aim This article is a report of a review that aimed to synthesize qualitative and quantitative evidence of ‘off-shifts’ (nights, weekends and/or holidays) on quality and employee outcomes in hospitals. Background Healthcare workers provide 24-hour-a-day, 7-day-a-week service. Quality and employee outcomes may differ on off-shifts as compared to regular hours. Data sources Searches for studies occurred between the years 1985–2011 using computerized databases including Business Source Complete, EconLit, ProQuest, PubMed and MEDLINE. Review design and methods Design was a mixed-method systematic review with quantitative and qualitative studies. To be included, studies met the following criteria: (1) the independent variable was an off-shift; (2) the article was a research study and peer-reviewed; (3) the article could be obtained in English; and (4) the article pertained to health care. Studies were not excluded on design. Results Sixty studies were included. There were 37 quality outcome, 19 employee outcome and four qualitative studies. In the quality outcome studies, researchers often used quantitative, longitudinal study designs with large sample sizes. Researchers found important differences between patients admitted on weekends and mortality. Important differences were also found between nighttime birth and mortality and rotating night work and fatigue, stress and low mental well-being. Most studies (9 of 12) did not find an important association between patients admitted at night and mortality. Conclusion Patient outcomes on weekends and employee outcomes at night are worse than during the day. It is important to further investigate why care on off-shifts differs from weekly day shifts.

This study investigated the clinical effectiveness of intervention with an open-mouth exercise device designed to facilitate maximal interincisal opening (MIO) and improve quality of life in patients with head and neck (H&N) cancer and oral submucous fibrosis (OSF). Sixty patients with H&N cancer, OSF, and trismus (MIO < 35 mm) participated in the functional rehabilitation program. An open-mouth exercise device intervention group and conventional group, each consisting of 20 patients, underwent a 12-week training and exercising program and follow-up. For the control group, an additional 20 patients were randomly selected to match the demographic characteristics of the aforementioned two groups. The patients' MIO improvements in the aforementioned three groups were 14.0, 10.5, and 1.3 mm, respectively. Results of this study confirm the significant improvement in average mouth-opening range. In addition, according to patient feedback, significant improvements in health-related quality of life and reductions in trismus symptoms occurred in the open-mouth exercise device group. This newly designed open-mouth exercise device can facilitate trismus patients with H&N cancer and OSF and improve mouth-opening range and quality of life.

The purpose of this study was to evaluate the methodological quality of nursing studies using structural equation modeling in Korea. Databases of KISS, DBPIA, and National Assembly Library up to March 2014 were searched using the MeSH terms 'nursing', 'structure', 'model'. A total of 152 studies were screened. After removal of duplicates and non-relevant titles, 61 papers were read in full. Of the sixty-one articles retrieved, 14 studies were published between 1992 and 2000, 27, between 2001 and 2010, and 20, between 2011 and March 2014. The methodological quality of the review examined varied considerably. The findings of this study suggest that more rigorous research is necessary to address theoretical identification, two indicator rule, distribution of sample, treatment of missing values, mediator effect, discriminant validity, convergent validity, post hoc model modification, equivalent models issues, and alternative models issues should be undergone. Further research with robust consistent methodological study designs from model identification to model respecification is needed to improve the validity of the research.

The purpose of this pilot quasi-experimental study was to examine the feasibility and preliminary efficacy of using Facebook in a 10-week lifestyle intervention with Head Start caregiver-preschooler dyads to improve healthy behaviors and reduce body mass index. Sixty-nine dyads participated with 39 in the intervention group. Average preschooler attendance rate for the Head Start center-based program was 77%, and caregiver participation rate was 87%. About 94% of the caregivers were satisfied with the program, and 97% would recommend the program to others and/or participate again. The intervention decreased preschoolers' body mass index z score (Cohen's d = -.30) and screen time ( d = -.21), and increased their fruit and vegetable intake ( d = .40) and moderate-to-vigorous physical activity ( d = .42). The intervention increased caregivers' fruit and vegetable intake ( d = .40). The intervention is feasible, and preliminary efficacy is encouraging, but further investigation using a rigorous study design is warranted.

To describe the basis on which our knowledge of frequent attendance in general practice rests and to propose recommendations for further research on frequent attenders (FAs). The literature review (finished February 2004) encompassed peer-reviewed articles in English describing contacts with general practice in terms of frequency. Searches were performed in the Medline, CINAHL, EMBASE, PsycINFO, Social Sciences Expanded Index and ISI Citation databases with additional searches in reference lists and the 'related articles' function in the ISI Citation database and Medline. General practice. Sixty-one articles (54 studies). The articles were assessed according to the following design variables: setting; definition of FAs; sampling; sample size; control groups; study aim; study design; data sources; effect measure; and main results. There was no generally accepted definition of frequent attendance. Research designs differed substantially. Eight articles gave sufficient information on all design variables. The top 10% of attenders accounted for 30-50% of all contacts, and up to 40% of FAs were still FAs the following year. More than 50% of FAs had a physical disease, more than 50% of FAs suffered from psychological distress, social factors (low social support, unemployment, divorce) were associated with frequent attendance in more than 50% of FAs, multiproblems (physical, psychological and social) were found in one-third of FAs, and frequent attendance was associated with increasing age and female gender. The diversity of designs, definitions and methods in the current literature on FAs in general practice hampers comparison of their precision, validity and generalizability, and calls for cautious interpretation and adoption of a common, generally acceptable definition in future studies.

Experience using individually supplied heater rods in critical power testing of advanced BWR fuel

The ABB Atom FRIGG loop located in Vasteras Sweden has during the last six years given a large experience of critical power measurements for BWR fuel designs using indirectly heated rods with individual power supply. The loop was built in the sixties and designed for maximum 100 bar pressure. Testing up to the mid eighties was performed with directly heated rods using a 9 MW, 80 kA power supply. Providing test data to develop critical power correlations for BWR fuel assemblies requires testing with many radial power distributions over the full range of hydraulic conditions. Indirectly heated rods give largemore » advantages for the testing procedure, particularly convenient for variation of individual rod power. A test method being used at Stern Laboratories (formerly Westinghouse Canada) since the early sixties, allows one fuel assembly to simulate all required radial power distributions. This technique requires reliable indirectly heated rods with independently controlled power supplies and uses insulated electric fuel rod simulators with built-in instrumentation. The FRIGG loop was adapted to this system in 1987. A 4MW power supply with 10 individual units was then installed, and has since been used for testing 24 and 25 rod bundles simulating one subbundle of SVEA-96/100 type fuel assemblies. The experience with the system is very good, as being presented, and it is selected also for a planned upgrading of the facility to 15 MW.« less

OBJECTIVE: To measure the prevalence of posttraumatic stress disorder and emotional distress among victims of the Saguenay flood compared with those who were not affected by the flood. DESIGN: Cross-sectional study using a telephone survey of victims and a control group. SETTING: Chicoutimi, Que. PARTICIPANTS: Sixty-two adults in a flooded area and a control group of 79 volunteers chosen randomly from an adjacent area. MAIN OUTCOME MEASURES: Diagnostic criteria for posttraumatic stress disorder measured using the Post-traumatic Stress Disorder Reaction Index and high scores on the Self-Reporting Questionnaire on emotional distress. RESULTS: Socially and demographically, study group and control group were comparable. Prevalence of posttraumatic stress disorder in the study group was close to 20% (odds ratio [OR] 6.08; 95% confidence interval [CI] 1.63 to 22.64). Prevalence of emotional distress in the study group was 29% (OR 2.42; 95% CI 1.04 to 5.61). CONCLUSION: The Saguenay flood caused psychological distress that was measurable 4 months later. Health care professionals should be aware of the psychological effects of natural disasters. PMID:11153409

We described the treatment rationale and procedure for a phase II study of docetaxel plus ramucirumab for non-small cell lung cancer (NSCLC) patients with brain metastasis (RAMNITA study: University Information Network Clinical Trials Registry identification no. [UMIN]: 000024551). Combination therapy of angiogenetic inhibitor with chemotherapy improved the outcome of patients with brain metastasis in previous reports; however, the efficacy of ramucirumab, a vascular endothelial growth factor receptor-2 monoclonal antibody, for brain metastasis has not been shown. This RAMNITA study is a prospective, multicenter, open-label, single-arm phase II study designed to evaluate efficacy and safety of docetaxel and ramucirumab for advanced NSCLC patients with brain metastasis. Eligible patients will receive docetaxel (60 mg/m) and ramucirumab (10 mg/kg) every 21 days until disease progression. The primary endpoint is progression-free survival (PFS), and secondary endpoints are overall survival, intracranial PFS, response rate, and safety. Sixty-five participants will be recruited from September 2017 to December 2019 and followed up for 1 year after final registration. The results from this study may suggest a treatment option for brain metastasis in NSCLC. The protocol was approved by the institutional review board of each study center. Written informed consent will be obtained from all patients before registration, in accordance with the Declaration of Helsinki.

Telephone hotlines designed to address common concerns in the early postpartum could be a useful resource for parents. Our aim was to test the feasibility of using a telephone as an intervention in a randomized controlled trial. We also aimed to test to use of algorithms to address parental concerns through a telephone hotline. Healthy first-time mothers were recruited from postpartum wards of hospitals throughout Lebanon. Participants were given the number of a 24-hour telephone hotline that they could access for the first four months after delivery. Calls were answered by a midwife using algorithms developed by the study team whenever possible. Callers with medical complaints were referred to their physicians. Call patterns and content were recorded and analyzed. Eighty-four of the 353 women enrolled (24%) used the hotline. Sixty percent of the women who used the service called more than once, and all callers reported they were satisfied with the service. The midwife received an average of three calls per day and most calls occurred during the first four weeks postpartum. Our algorithms were used to answer questions in 62.8% of calls and 18.6% of calls required referral to a physician. Of the questions related to mothers, 66% were about breastfeeding. Sixty percent of questions related to the infant were about routine care and 23% were about excessive crying. Utilization of a telephone hotline service for postpartum support is highest in the first four weeks postpartum. Most questions are related to breastfeeding, routine newborn care, and management of a fussy infant. It is feasible to test a telephone hotline as an intervention in a randomized controlled trial. Algorithms can be developed to provide standardized answers to the most common questions.

The aim of this study was to identify the most widely used financial, productivity, and accessibility metrics used by academic radiology departments (ARDs) in a dashboard format via a national survey. The results provide a guide to the selection of preferred or commonly used indicators to facilitate dashboard implementation and use. The study met the criteria for an exemption from institutional review board approval. A cross-sectional survey was conducted using a survey approved by the Society of Chairs of Academic Radiology Departments and sent to its members. The survey was designed to evaluate the adoption, access, and composition of dashboard technology in ARDs, particularly those related to measures of productivity and financial performance. The overall response rate was 42% (56 of 131 members). Sixty-two percent of responding ARDs currently use some form of dashboard technology, but 50% have used this technology for ≤2 years. Sixty-five percent of all ARDs use their dashboard information on a monthly basis. The two dashboard financial indicators most frequently used by ARDs are revenue and actual expenses. Similarly, the two productivity indicators used most widely are total examination volume and examination volume per modality. The two most important access indicators used are report turnaround time and backlog per unit time. Currently, fewer than two-thirds of the responding ARDs use dashboard technology, and one-half have used the technology for ≤2 years. Although some fiscal and productivity indices are more frequently used, there are a diverse number of factors used to measure productivity, finance, access, and other operational parameters in ARD dashboards. Thus, the information provided by each institutional dashboard may be significantly different from that in other ARDs. Copyright © 2013 American College of Radiology. Published by Elsevier Inc.

Background The benefits of exercise for reducing disability in people with Parkinson disease (PD) are becoming more evident. Optimal benefit, however, requires regular and sustained participation. Factors associated with engaging in regular exercise have received little scientific scrutiny in people with PD. Objective The purpose of this study was to explore factors associated with exercise behavior in patients with PD using the International Classification of Functioning, Disability and Health (ICF) as a guiding framework. Design This was a cross-sectional study. Methods The participants in this study were 260 patients with PD from 4 institutions. Participants were designated as “exercisers” or “nonexercisers” based on responses to the Stages of Readiness to Exercise Questionnaire. Exercise status was validated using the Physical Activity Scale for the Elderly and an activity monitor. Factors potentially associated with exercise behavior included measures of body structure and function, activity, participation, environmental factors, and personal factors. Their relative contributions were analyzed using logistic regression and quantified with odds ratios. Results One hundred sixty-four participants (63%) were designated as exercisers. Participants with high self-efficacy were more than twice as likely to engage in regular exercise than those with low self-efficacy (adjusted odds ratio=2.34, 95% confidence interval=1.30–4.23). College educated and older participants also were more likely to exercise. Disabling influences of impairments, activity limitations, and participation restrictions were not associated with exercise behavior. Limitations The cross-sectional nature of the study limited the ability to make causal inferences. Conclusions Self-efficacy, rather than disability, appears to be strongly associated with whether ambulatory, community-dwelling people with PD exercise regularly. The results of this study suggest that physical therapists should include strategies to increase exercise self-efficacy when designing patient intervention programs for patients with PD.

Preliminary design of a high speed civil transport: The Opus 0-001

NASA Technical Reports Server (NTRS)

1992-01-01

Based on research into the technology and issues surrounding the design, development, and operation of a second generation High Speed Civil Transport, HSCT, the Opus 0-001 team completed the preliminary design of a sixty passenger, three engine aircraft. The design of this aircraft was performed using a computer program which the team wrote. This program automatically computed the geometric, aerodynamic, and performance characteristic of an aircraft whose preliminary geometry was specified. The Opus 0-001 aircraft was designed for a cruise Mach number of 2.2, a range of 4,700 nautical miles and its design was based in current or very near term technology. Its small size was a consequence of an emphasis on a profitable, low cost program, capable of delivering tomorrow's passengers in style and comfort at prices that make it an attractive competitor to both current and future subsonic transport aircraft. Several hundred thousand cases of Cruise Mach number, aircraft size and cost breakdown were investigated to obtain costs and revenues for which profit was calculated. The projected unit flyaway cost was $92.0 million per aircraft.

Background: Above all methods effective learning results from decent training, acquired in the proper environment and encouraging creative methods. Computer-assisted training by educational software is considered a fundamental measure to improve medical and dentistry education systems. This study aims to design and assess fixed dental prostheses via 2 multimedia instructional contents at the Guilan dentistry school. Methods: This is a descriptive and cross-sectional study. First off, the instructional content was analyzed. The software used to produce multimedia was the iSpring suite Ver.7.0. After designing the instructional multimedia, this software was loaded by LMS. Sixty-nine dentistry students in the 5th semester at Guilan Dentistry School were selected via convenience sampling. At the end of the course, a structured questionnaire containing 26 items were handed to the students to evaluate the instructional multimedia quality. Results: Mean ±SD age was 24.68±3.24 years, 43 were women (62.4%) and 26 were men (37.6%) -the majority of 76.8% used the internet at home. A portion of 33.3% were inclined to use multimedia and the internet with in-person training. About 60% declared that multimedia quality as being good. Conclusion: the instructional multimedia designs which are compatible with lesson objectives and audiovisual facilities can have a great effect on the student's satisfaction. Preparing instructional multimedia makes the instructional content easily accessible for students to be able to review it several times at the proper opportunity and if presented through LMS they would be able to study the lesson subject wherever and whenever accessing the internet.

OBJECTIVE The purpose of this study was to estimate pharmacokinetic parameters and to evaluate placental transport of 17-hydroxyprogesterone caproate (17-OHPC) in singleton gestation. STUDY DESIGN Sixty-one women who received weekly injections of 17-OHPC underwent 2 pharmacokinetic studies at 20 + 0 to 24 + 6 weeks’ gestation (study 1) and 31 + 0 to 34 + 6 weeks’ gestation (study 2); daily blood samples were obtained between injections. In 18 women, blood samples were obtained over a 28-day period beyond the last injection (extended study). Maternal and/or cord blood were obtained at delivery. RESULTS The half-life (median ± SD) of 17-OHPC was 16.2 ± 6 days. Concentrations of 17-OHPC were higher during study 2 than during study 1. Body mass index affected maternal 17-OHPC concentrations. Cord:maternal 17-OHPC concentration ratios averaged 0.2; 17-OHPC was detectible in cord plasma 44 days after the last maternal injection. CONCLUSION The apparent half-life of 17-OHPC is long, and pharmacokinetic parameters vary widely between subjects and are affected by maternal body mass index. The drug crosses the placental barrier.

Background: Fractures shaft femur is a major cause of morbidity and mortality in patients with lower extremity injuries. Aims: The aim of this study was to evaluate the efficacy of intramedullary Kirschner wires for the treatment of femoral shaft fracture in children. Subjects and Methods: This prospective study was conducted in the Department of Orthopaedic surgery in M. M. Medical College from June 2005 to June 2010. Sixty eight children with a mean age of 7.7 years (range, 2-14 years) were recruited from Emergency and out patient department having closed fracture of femoral shaft. All patients were operated under general anesthesia. All patients were followed for twelve months. Results: Out of sixty eight patients, sixty four patients underwent union in 42 to 70 days with a mean of 56 days. Touch down weight bearing was started on 2nd post-operative day. Complications found in four patients who had insignificant delayed union which were united next three weeks. Intramedullary Kirschner-wires were removed after an average of five months without any complications. The results were excellent in 94.1% (64/68) and good in 5.8% (4/68). Conclusion: This technique is simple, quick to perform, safe and reliable and avoids prolonged hospitalization with good results and is economical. PMID:23919189

How do illness-anxious individuals process health-threatening information? A systematic review of evidence for the cognitive-behavioral model.

PubMed

Leonidou, Chrysanthi; Panayiotou, Georgia

2018-08-01

According to the cognitive-behavioral model, illness anxiety is developed and maintained through biased processing of health-threatening information and maladaptive responses to such information. This study is a systematic review of research that attempted to validate central tenets of the cognitive-behavioral model regarding etiological and maintenance mechanisms in illness anxiety. Sixty-two studies, including correlational and experimental designs, were identified through a systematic search of databases and were evaluated for their quality. Outcomes were synthesized following a qualitative thematic approach under categories of theoretically driven mechanisms derived from the cognitive-behavioral model: attention, memory and interpretation biases, perceived awareness and inaccuracy in perception of somatic sensations, negativity bias, emotion dysregulation, and behavioral avoidance. Findings partly support the cognitive-behavioral model, but several of its hypothetical mechanisms only receive weak support due to the scarcity of relevant studies. Directions for future research are suggested based on identified gaps in the existing literature. Copyright © 2018 Elsevier Inc. All rights reserved.

The aims of this study were to appreciate the prevalence of chronic low back pains in a public transport's company, to state characteristics and to identify categories of workers involved and medico-legal consequences. It is a cross sectional study. which used medical records of the occupational clinic. All workers who complained of low back pain in the past three years following the study were selected. Characteristics of workers, types of injuries, occupational and medico-legal consequences were looked out. Sixty nine cases were collected, they were exclusively males. 54 % of them were bus drivers, and 29% conductors. X rays abnormalities were found in 31.64%. Exposure to vibration due to damaged roads and decayed vehicles seems to be main etiologic factors. From a occupational and medico-legal standpoint, two patients were reported for workers compensation, three patients were reclassified in another job. Undamaged roads, ergonomic design of bus' seats, and medical screening during placement and routine medical examination are key issues in preventing low back pains.

A 16-year examination of domestic violence among Asians and Asian Americans in the empirical knowledge base: a content analysis.

PubMed

Yick, Alice G; Oomen-Early, Jody

2008-08-01

Until recently, research studies have implied that domestic violence does not affect Asian American and immigrant communities, or even Asians abroad, because ethnicity or culture has not been addressed. In this content analysis, the authors examined trends in publications in leading scholarly journals on violence relating to Asian women and domestic violence. A coding schema was developed, with two raters coding the data with high interrater reliability. Sixty articles were published over the 16 years studied, most atheoretical and focusing on individual levels of analysis. The terms used in discussing domestic violence reflected a feminist perspective. Three quarters of the studies were empirical, with most guided by logical positivism using quantitative designs. Most targeted specific Asian subgroups (almost a third focused on Asian Indians) rather than categorizing Asians as a general ethnic category. The concept of "Asian culture" was most often assessed by discussing Asian family structure. Future research is discussed in light of the findings.

Risk minimization in research with bereaved parents is important. However, little is known about which research methods balance the sensitivity required for bereaved research participants and the need for generalizable results. To explore parental experiences of participating in mixed method bereavement research via a pilot study. A convergent parallel mixed method design assessing bereaved parents' experience of research participation. Eleven parents whose child was treated for cancer at The Royal Children's Hospital, Brisbane completed the questionnaire/interview being piloted (n = 8 mothers; n = 3 fathers; >6 months and <6 years bereaved). Of these, eight parents completed the pilot study evaluation questionnaire, providing feedback on their experience of participation. Participants acknowledged the importance of bereaved parents being central to research design and the development of bereavement programs. Sixty-three per cent (n = 5/8) of parents described completion of the questionnaire as 'not at all/a little bit' of a burden. Seventy-five per cent (n = 6/8) of parents opting into the telephone interview described participation as 'not at all/a little bit' of a burden. When considering the latest timeframes for participation in bereavement research 63% (n = 5/8) of parents indicated 'no endpoint.' Findings from the pilot study enabled important adjustments to be made to a large-scale future study. As a research method, pilot studies may be utilized to minimize harm and maximize the potential benefits for vulnerable research participants. A mixed method approach allows researchers to generalize findings to a broader population while also drawing on the depth of the lived experience.

2014-01-01

The purpose of this study was to identify nurse educators' stage of concern regarding e-books and examine relationships between stage of concern and demographic variables. The use of e-books is growing, and nursing faculty must be prepared to use this evolving technology. A descriptive design was used with a convenience sample of 50 nurse educators attending a professional conference. Data were collected using a demographic questionnaire and the Stages of Concern (SoC) questionnaire. Sixty-four percent of participants' first high stage was Stage 0 (awareness); 22 percent had a first high stage of Stage 1 (informational). Using ordinal regression, no statistical significance was noted with the highest Stage of Concern and age (p = .431) or experience as a nurse educator (p = .893). Findings indicate low usage, faculty concerns, and the need for ongoing education regarding e-books.

Objective The primary aim of this study is to establish the validity of greyscale-based quantitative ultrasound (QUS) measures of the biceps and supraspinatus tendons. Design Nine QUS measures of the biceps and supraspinatus tendons were computed from ultrasound images collected from sixty-seven manual wheelchair users. Shoulder pathology was measured using questionnaires, physical examination maneuvers, and a clinical ultrasound grading scale. Results Increased age, duration of wheelchair use, and body mass correlated with a darker, more homogenous tendon appearance. Subjects with pain during physical examination tests for biceps tenderness and acromioclavicular joint tenderness exhibited significantly different supraspinatus QUS values. Even when controlling for tendon depth, QUS measures of the biceps tendon differed significantly between subjects with healthy tendons, mild tendinosis, and severe tendinosis. Clinical grading of supraspinatus tendon health was correlated with QUS measures of the supraspinatus tendon. Conclusions Quantitative ultrasound is valid method to quantify tendinopathy and may allow for early detection of tendinosis. Manual wheelchair users are at a high risk for developing shoulder tendon pathology and may benefit from quantitative ultrasound-based research that focuses on identifying interventions designed to reduce this risk.

To conduct a pilot test of a brief, self-guided, home-based program designed to improve male condom use attitudes and behaviors among young women. Women aged 18-24 years from a large Midwestern University reporting having had penile-vaginal sex with two or more partners in the past 3 months. Sixty-seven enrolled; 91.0% completed the study. A repeated measures design was used, with assessments occurring at baseline, immediately  post intervention (T2), and 30 days subsequent (T3). Condom use errors and problems decreased, condom-related attitudes and self-efficacy improved, and experiences of condom-protected sex were rated more positively when comparing baseline with T2 and T3 scores. Further, the proportion of condom-protected episodes more than doubled between T1 and T3 for those in the lowest quartile for condom use at baseline. This low-resource, home-based program improved condom-related attitudes and promoted the correct and consistent use of condoms.

This study was designed to empirically examine the effects of iPod device and text-messaging activities on driver distraction. Sixty participants were asked to perform a driving simulation task while searching for songs using an iPod device or text messaging. Driving errors as measured by lane deviations were recorded and analyzed as a function of the distracters. Physiological measures (EEG) were also recorded during the driving phases in order to measure participant levels of cortical arousal. It was hypothesized that iPod use and text messaging would result in a profound effect on driving ability. The results showed a significant effect of iPod use and text-messaging on driving performance. Increased numbers of driving errors were recorded during the iPod and text-messaging phases than the pre- and post-allocation phases. Higher levels of Theta activity were also observed during the iPod and Text-messaging phase than the pre- and post-allocation phases. Implications for in-vehicle systems design, training, and safety are also discussed.

Catching Fish and Avoiding Sharks: Investigating Factors That Influence Developmentally Appropriate Measurement of Preschoolers' Inhibitory Control.

PubMed

Howard, Steven J; Okely, Anthony D

2015-09-01

Although researchers agree that the first 5 years of life are critical for children's developing executive functions (EFs), further advances are hindered by a lack of consensus on the design and selection of developmentally appropriate EF tasks for young children. Given this debate, well-established adult measures of EF routinely have been adapted for young children. Given young children's comparatively limited cognitive capacities, however, such adaptations do not guarantee that the task's critical EF demands are retained. To investigate this possibility, the current study examined the characteristics that optimize measurement of young children's EFs-specifically, their inhibitory control-using the go/no-go (GNG) task as an exemplar. Sixty preschoolers completed six GNG tasks differing in stimulus animation, presentation time, and response location. Comparison EF tasks were administered to examine concurrent validity of GNG variants. Results indicated effects of stimulus presentation time and response location, with animation further enhancing task validity and reliability. This suggests that current GNG tasks deflate estimates of young children's ability to inhibit, with implications for future design and selection of developmentally appropriate EF tasks.

To describe the clinical characteristics, serologic, radiological and clinical disease activity, and modality of therapy in patients with rheumatoid arthritis (RA) at tertiary outpatient care in Qatar. The study design was cross-sectional where 100 consecutive cases who met 1987 American College of Rheumatology criteria for diagnosis of RA were enrolled in this study. Demographic data (sex, nationality and age) numbers of swollen and tender joints, X-rays and current medications were collected during outpatients visits to Hamad General Hospital. Disease Activity Score of 28 joints (DAS28) and Health Assessment Questionnaires (HAQ) scores were calculated. All patients with RA who were seen as rheumatology outpatients were invited to participate in the study. One hundred patients were seen and examined during their follow-up at the outpatient clinic; data were collected and analyzed. Females represented 67% of all patients, 6% had more than six swollen joints, 9% had more than six tender joints. DAS28 and erythrocyte sedimentation rate (DAS28) calculation revealed 49% of patients were in remission (DAS28 < 2.6), 15% had low disease activity (DAS28 2.6-3.2) and 36% had DAS28 > 3.2.Mean HAQ score was 1.02. Rheumatoid factor (RF) was positive in 63%, while anti-cyclic citrullinated protein antibody (anti-CCP) was positive in 71%, and 49% were positive for both. Radiography of hands and feet during the previous year was done in 65% of patients: 11% of them had erosions. Sixty-six percent were on one synthetic disease-modifying anti-rheumatic drug (DMARD) and 27% where on more than one synthetic DMARD and 7% where on no DMRD. Glucocorticoids were used in 51% and 29% were on biologics. Sixty-four percent of rheumatoid arthritis patients in Qatar were in remission or had low disease activity while the remaining 36% had active disease and among these patients 29% were on biologics. © 2013 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

1986-07-01

This article reports on five separate studies designed for the National Library of Medicine (NLM) to develop and test methodologies for evaluating the products of large databases. The methodologies were tested on literatures of the medical behavioral sciences (MBS). One of these studies examined how well NLM covered MBS monographic literature using CATLINE and OCLC. Another examined MBS journal and serial literature coverage in MEDLINE and other MBS-related databases available through DIALOG. These two studies used 1010 items derived from the reference lists of sixty-one journals, and tested for gaps and overlaps in coverage in the various databases. A third study examined the quality of the indexing NLM provides to MBS literatures and developed a measure of indexing as a system component. The final two studies explored how well MEDLINE retrieved documents on topics submitted by MBS professionals and how online searchers viewed MEDLINE (and other systems and databases) in handling MBS topics. The five studies yielded both broad research outcomes and specific recommendations to NLM.

Objective Although awareness of sleep disorders is increasing, limited information is available on whole night detection of snoring. Our study aimed to develop and validate a robust, high performance, and sensitive whole-night snore detector based on non-contact technology. Design Sounds during polysomnography (PSG) were recorded using a directional condenser microphone placed 1 m above the bed. An AdaBoost classifier was trained and validated on manually labeled snoring and non-snoring acoustic events. Patients Sixty-seven subjects (age 52.5±13.5 years, BMI 30.8±4.7 kg/m2, m/f 40/27) referred for PSG for obstructive sleep apnea diagnoses were prospectively and consecutively recruited. Twenty-five subjects were used for the design study; the validation study was blindly performed on the remaining forty-two subjects. Measurements and Results To train the proposed sound detector, >76,600 acoustic episodes collected in the design study were manually classified by three scorers into snore and non-snore episodes (e.g., bedding noise, coughing, environmental). A feature selection process was applied to select the most discriminative features extracted from time and spectral domains. The average snore/non-snore detection rate (accuracy) for the design group was 98.4% based on a ten-fold cross-validation technique. When tested on the validation group, the average detection rate was 98.2% with sensitivity of 98.0% (snore as a snore) and specificity of 98.3% (noise as noise). Conclusions Audio-based features extracted from time and spectral domains can accurately discriminate between snore and non-snore acoustic events. This audio analysis approach enables detection and analysis of snoring sounds from a full night in order to produce quantified measures for objective follow-up of patients. PMID:24391903

To examine advance care planning practices and proxy decision making by family healthcare proxies for patients with advanced Parkinson disease (PD). Sixty-four spouses and adult children, self-designated as a/the healthcare proxy for advanced patients with PD, participated in a cross-sectional survey study. Sixty patients with PD (95%) had completed a living will, but only 38% had shared the document with a physician. Among three life-support treatments--cardiopulmonary resuscitation (CPR), ventilator, and feeding tube--47% of patients opted for CPR, 16% for ventilator, and 20% for feeding tube. Forty-two percent of proxies did not know patients' preferences for one or more of the three life-support treatments. Only 28% of proxies reported that patients wanted hospice. Patients who shared advance directives with a physician were significantly less likely to choose CPR and a feeding tube and they were more likely to choose hospice. In a hypothetical end-of-life (EOL) scenario, the majority of proxies chose comfort care as the EOL goal of care (53%) and pain and symptom management only as the course of treatment option (72%); these proxy choices for patients, however, were not associated with patients' preferences for life support. Patients' proxies preferred a form of shared decision making with other family members and physicians. Advance care planning is effective when patients, families, and healthcare professionals together consider future needs for EOL care decisions. Further efforts are needed by healthcare professionals to provide evidence-based education about care options and facilitate advanced discussion and shared decision making by the patient and families.

Sixty professional soccer players (30 male and 30 female) were divided into three groups, according to their playing position: defenders, midfielders and attackers. Each group consisted of 10 male and 10 female players. Sixty healthy volunteers (30 males and 30 females) served as control. Blood samples were taken before and after the match and daily for five days after the match. Analysis of variance revealed different responses over time between sex and playing positions, as shown by the 3-way interaction, for creatine kinase (CK), protein carbonyls (PC), catalase, fibrinogen (FIB), uric acid (UA), lactate dehydrogenase (LDH), reduced glutathione, C-reactive protein and interleukin-6 (IL-6) (p < 0.01).Male players had higher values compared with females of the same playing position, for all oxidative, inflammatory and muscle damage indices (p<0.01). Also, in both sexes, midfielders had higher peaks in all indices compared with defenders (p < 0.05). Five days after the game CK and UA concentrations had not returned to pre-game levels in any exercise group, whereas PC were still elevated in male midfielders and attackers (p < 0.05).These results show that sex and playing position influence the time-course of selected oxidative stress, inflammation and muscle damage markers following an official soccer game. This information should be taken into account by practitioners for the design of training programs following match play.

In 1997, pesticide concentrations were measured in mountain yellow-legged frogs (Rana muscosa) from two areas in the Sierra Nevada Mountains of California, USA. One area (Sixty Lakes Basin, Kings Canyon National Park) had large, apparently healthy populations of frogs. A second area (Tablelands, Sequoia National Park) once had large populations, but the species had been extirpated from this area by the early 1980s. The Tablelands is exposed directly to prevailing winds from agricultural regions to the west. When an experimental reintroduction of R. muscosa in 1994 to 1995 was deemed unsuccessful in 1997, the last 20 (reintroduced) frogs that could be found were collected from the Tablelands, and pesticide concentrations in both frog tissue and the water were measured at both the Tablelands and at reference sites at Sixty Lakes. In frog tissues, dichlorodiphenyldichloroethylene (DDE) concentration was one to two orders of magnitude higher than the other organochlorines (46 ?? 20 ng/g wet wt at Tablelands and 17 ?? 8 Sixty Lakes). Both ??-chlordane and trans-nonachlor were found in significantly greater concentrations in Tablelands frog tissues compared with Sixty Lakes. Organophosphate insecticides, chlorpyrifos, and diazinon were observed primarily in surface water with higher concentrations at the Tablelands sites. No contaminants were significantly higher in our Sixty Lakes samples.

The objectives of this study were to evaluate registered nurses' (RN) compliance with a local clinical central venous access device (CVAD) protocol after completing an educational program and to determine RNs' perception of the program. Seventy-five RNs working in hematology participated in the educational part of the program. Sixty-eight RNs were examined while changing CVAD dressings or placing a Huber needle into a port on actual patients. Sixty percent of the RNs passed the examination and reported that the program increased their knowledge. The results indicated that the educational program could be recommended for use when implementing a new clinical protocol.

Academic attainment in children with Autism Spectrum Disorder (ASD) is under-studied, with associated factors largely undetermined. Parent-reported attention symptoms, attentional-switching and sustained-attention tasks were examined to determine relationships with mathematics and reading attainment in 124 children aged 7-12 years; sixty-four with high-functioning ASD, half girls, and sixty age- and gender-matched typical children (TYP). With full-scale IQ controlled there were no differences in mathematics, reading, attentional switching or sustained attention. In regression analysis, attentional switching was related to mathematics achievement in ASD but not TYP children. Findings highlight attentional switching difficulties are linked with poorer mathematics outcomes in ASD.

To study the clinical and pathologic features of granulomatous lobular mastitis (GLM). Sixty-eight cases of GLM were retrieved from the archival file. The clinical data and histologic features were retrospectively reviewed. Sixty-eight patients presented with breast mass. Ulceration in overlying breast skin was seen in 9 cases. Most of the patients had history of breast feeding. None of them had evidence of specific infections involving the breast. The clinical and radiologic features mimicked malignancy. Histologically, GLM was characterized by the presence of non-necrotizing granulomas, usually admixed with neutrophils and associated with benign ductolobular units. The ductolobular architecture was still preserved. The duration of follow up ranged from 6 to 36 months. Four patients suffered from disease recurrence. GLM shows clinical and radiologic features reminiscent of breast cancer. Correct diagnosis requires histologic examination of the biopsy specimens.

The purpose of this study was to assess radiographer familiarity and preferences with digital radiography in four teaching hospitals and thereafter make recommendations in line with the migration from screen film to digital radiography. A questionnaire was designed to collect data from either qualified or student radiographers from four teaching hospitals. From the four teaching hospitals, there were a total of 205 potential respondents. Among other things, responses regarding experiences and preferences with digital radiography, quality control procedures, patient dose, advantages and disadvantages of digital radiography were sought. The information collected was based on self-reporting by the participants. The study is exploratory in nature and descriptive statistics were generated from the collected data using Microsoft Excel 2007 and StatsDirect software. Sixty-three out of 205 (31%) radiographers from all the four radiology centers responded to the circulated questionnaire. Only 15% (8) of the qualified radiographers had 4 or more years of experience with digital radiography compared to 68% (36) for the same amount of experience with screen-film radiography. Sixty-one percent (38) of the participants had been exposed to digital radiography during their lectures while at university. A small proportion, 16% (10) of the respondents underwent formal training in quality control procedures on the digital X-ray units they were using. Slightly more than half (55%) of the participants felt it was easier for them to retake an image in digital radiography than in screen film radiography. The results of this survey showed that the participants are familiar with digital radiography and have embraced this relatively new technology as shown by the fact that they can identify both its advantages and disadvantages as applied to clinical practice. However, there are minimal quality control procedures specific to digital radiography being undertaken as such there is need for formal education, continuing education and manufacturer training with respect to quality control as institutions make the transition from conventional screen film radiology to digital radiology.

Epidemiologic studies have shown an association between mouse allergen exposure and asthma morbidity among urban populations, but confirmatory challenge studies in community populations have not been performed. This study was designed to examine the clinical relevance of mouse sensitization using a nasal challenge model. Forty-nine urban adults with asthma underwent skin-prick testing (SPT) and intradermal testing (IDT) with mouse epithelia extract. A positive SPT was defined as a net wheal size ≥3 mm and a positive IDT was defined as a net wheal size ≥6 mm using a 1:100 dilution of extract (1:10 w/v was obtained from Greer Laboratories (Lenoir, NC) as a single lot [Mus m 1 concentration = 2130 ng/mL]). Mouse-specific IgE (m-IgE) was measured by ImmunoCAP (Phadia, Uppsala, Sweden). Nasal challenge was performed with increasing concentrations of mouse epithelia extract and symptoms were assessed by visual analog scale. A positive challenge was defined as a 20-mm increase in the scale. The age range of the 49 participants was 18-50 years; 41% were men and 86% were black. Fourteen participants were SPT(+) to mouse, 15 participants were SPT(-) but (IDT(+)), and 20 participants were negative on both SPT(-) and IDT(-) (SPT(-)/IDT(-)). Sixty-four percent of the SPT(+) group, 40% of the IDT(+) group, and 20% of the SPT(-)/IDT(-) group had a positive nasal challenge. Sixty-seven percent (10/15) of those who were either SPT(+) or m-IgE(+) had a positive nasal challenge. SPT or the combination of SPT plus m-IgE performed best in diagnosing mouse allergy. The great majority of mouse-sensitized urban adults with asthma appear to have clinically relevant sensitization. Urban adults with asthma should be evaluated for mouse sensitization using SPT or SPT plus m-IgE testing.

Hard-on-hard bearings offer the potential to improve the survivorship of total hip arthroplasty implants. However, the specific indications for the use of these advanced technologies remain controversial. The purpose of this study was to characterize the epidemiology of bearing surface utilization in total hip arthroplasty in the United States with respect to patient, hospital, geographic, and payer characteristics. The Nationwide Inpatient Sample database was used to analyze bearing type and demographic characteristics associated with 112,095 primary total hip arthroplasties performed in the United States between October 1, 2005, and December 31, 2006. The prevalence of each type of total hip arthroplasty bearing was calculated for population subgroups as a function of age, sex, census region, payer class, and hospital type. The most commonly reported bearing was metal-on-polyethylene (51%) followed by metal-on-metal (35%) and ceramic-on-ceramic (14%). Metal-on-polyethylene bearings were most commonly reported in female Medicare patients who were sixty-five to seventy-four years old, while metal-on-metal and ceramic-on-ceramic bearings were most commonly reported in privately insured male patients who were less than sixty-five years old. Thirty-three percent of patients over sixty-five years old had a hard-on-hard bearing reported. There was substantial regional variation in bearing usage; the highest prevalence of metal-on-polyethylene bearings was reported in the Northeast and at nonteaching hospitals, and the highest prevalence of metal-on-metal bearings was reported in the South and at teaching hospitals. The usage of total hip arthroplasty bearings varies considerably by patient characteristics, hospital type, and geographic location throughout the United States. Despite uncertain advantages in older patients, hard-on-hard bearings are commonly used in patients over the age of sixty-five years. Further study is necessary to define the appropriate indications for these advanced technologies in total hip arthroplasty.

Protein Kinase C β-II (PKC β-II) is an important enzyme in the development of diabetic complications like cardiomyopathy, retinopathy, neuropathy, nephropathy and angiopathy. PKC β-II is activated in vascular tissues during diabetic vascular abnormalities. Thus, PKC β-II is considered as a potent drug target and the crystal structure of the kinase domain of PKC β-II (PDB id: 2I0E) was used to design inhibitors using Structure-Based Drug Design (SBDD) approach. Sixty inhibitors structurally similar to Staurosporine were retrieved from PubChem Compound database and High Throughput Virtual screening (HTVs) was carried out with PKC β-II. Based on the HTVs results and the nature of active site residues of PKC β-II, Staurosporine inhibitors were designed using SBDD. Induced Fit Docking (IFD) studies were carried out between kinase domain of PKC β-II and the designed inhibitors. These IFD complexes showed favorable docking score, glide energy, glide emodel and hydrogen bond and hydrophobic interactions with the active site of PKC β-II. Binding free energy was calculated for IFD complexes using Prime MM-GBSA method. The conformational changes induced by the inhibitor at the active site of PKC β-II were observed for the back bone Cα atoms and side-chain chi angles. PASS prediction tool was used to analyze the biological activities for the designed inhibitors. The various physicochemical properties were calculated for the compounds. One of the designed inhibitors successively satisfied all the in silico parameters among the others and seems to be a potent inhibitor against PKC β-II. PMID:22829732

The aim of this study was to evaluate the effect of daily consumption and/or application of argan oil on skin hydration in postmenopausal women. Sixty postmenopausal women consumed butter during the stabilization period and were randomly divided into two groups for the intervention period: the treatment group absorbed alimentary argan oil (n = 30) and the control group olive oil (n = 30). Both groups applied cosmetic argan oil in the left volar forearm during a sixty days' period. Evaluation of skin hydration, i.e. transepidermal water loss (TEWL) and water content of the epidermis (WCE) on both volar forearms of the two groups, were performed during three visits at D0, D30 and after sixty days (D60) of oils treatment. The consumption of argan oil has led to a significant decrease in TEWL (p = 0.023) and a significant increase in WCE (p = 0.001). The application of argan oil has led to a significant decrease in TEWL (p = 0.01) and a significant increase in WCE (p < 0.001). Our findings suggest that the daily consumption and application of argan oil have improved the skin hydration by restoring the barrier function and maintaining the water-holding capacity.

This paper highlights the effect of visual of a multimedia courseware, Black Cat Courseware (BC-C), developed for learning literature at a pre-university level in University Teknologi PETRONAS (UTP). The contents of the courseware are based on a Black Cat story which is covered in an English course at the university. The objective of this paper is to evaluate the usability and effectiveness of BC-C. A total of sixty foundation students were involved in the study. Quasi-experimental design was employed, forming two groups: experimental and control groups. The experimental group had to interact with BC-C as part of the learning activities while the control group used the conventional learning methods. The results indicate that the experimental group achieved a statistically significant compared to the control group in understanding the Black Cat story. The study result also proves that the effect of visual increases the students' performances in literature learning at a pre-university level.

Clinical reasoning is one of the most important competencies that a physician should achieve. Many medical schools and licensing bodies try to predict it based on some general measures such as critical thinking, personality, and emotional intelligence. This study aimed at providing a model to design the relationship between the constructs. Sixty-nine medical students participated in this study. A battery test devised that consist four parts: Clinical reasoning measures, personality NEO inventory, Bar-On EQ inventory, and California critical thinking questionnaire. All participants completed the tests. Correlation and multiple regression analysis consumed for data analysis. There is low to moderate correlations between clinical reasoning and other variables. Emotional intelligence is the only variable that contributes clinical reasoning construct (r=0.17-0.34) (R(2) chnage = 0.46, P Value = 0.000). Although, clinical reasoning can be considered as a kind of thinking, no significant correlation detected between it and other constructs. Emotional intelligence (and its subscales) is the only variable that can be used for clinical reasoning prediction.

We designed the present study to determine the effect of occupational exposure to asphalt fumes on oxidative status and DNA damage in road paving workers. Sixty road paving workers exposed to asphalt fumes and forty non-exposed control subjects were recruited. Occupational exposure to PAHs was assessed by urinary 1-hydroxypyrene (1-OHP) excretion. Serum thiol disulfide homeostasis (TDH), total oxidant status (TOS) and total antioxidant status (TAS) and urinary 8-hydro-deoxyguanosine (8-OH-dG) level were evaluated by automated colourimetric method. The urinary concentrations of 1-OHP and 8-OH-dG were significantly higher in the exposed group than in the control group (P < 0.001). Disulfide/thiol ratio, TOS, and TAS were also significantly higher for the asphalt workers. A positive correlation existed between urinary 1-OHP and 8-OH-dG, TOS and TAS. Study results indicate that exposure to PAHs induces oxidative stress and causes genotoxic effects in asphalt workers. © 2018 Wiley Periodicals, Inc.

Gambling may constitute a strategy for coping with depressive mood, but a direct influence of depressive mood on gambling behaviors has never been tested via realistic experimental designs in gamblers. The current study tested whether experimentally induced sadness increases persistence on a simulated slot machine task using real monetary reinforcement in recreational gamblers. Sixty participants were randomly assigned to an experimental (sadness induction) or control (no emotional induction) condition, and then performed a slot machine task consisting of a mandatory phase followed by a persistence phase. Potential confounding variables (problem gambling symptoms, impulsivity traits, gambling cognitions) were measured to ensure that the experimental and control groups were comparable. The study showed that participants in the sadness condition displayed greater gambling persistence than control participants (p = .011). These data support the causal role of negative affect in decisions to gamble and persistence, which bears important theoretical and clinical implications.

Objective Using a mixed model design, this study examined the effects of interactive versus passive distraction on healthy preschool-aged children’s cold pressor pain tolerance. Methods Sixty-one children aged 3–5 years were randomly assigned to one of the following: interactive distraction, passive distraction, or no distraction control. Participants underwent a baseline cold pressor trial followed by interactive distraction trial, passive distraction trial, or second baseline trial. One or two additional trials followed. Children originally assigned to distraction received the alternate distraction intervention. Controls participated in both interactive and passive distraction trials in counterbalanced order. Results Participants showed significantly higher pain tolerance during both interactive and passive distraction relative to baseline. The two distraction conditions did not differ. Conclusions Interactive and passive video game distraction appear to be effective for preschool-aged children during laboratory pain exposure. Future studies should examine whether more extensive training would enhance effects of interactive video game distraction. PMID:21278378

To assess whether there was any significant difference in the average fractional urinary fluoride excretion (FUFE) values among adults consuming (NaF) fluoridated Ca-free water (reference water), naturally fluoridated hard water and an artificially (H2SiF6) fluoridated soft water. Sixty adult females (N=20 for each treatment) participated in this randomized, double-blind trial. The experimental design of this study provided an indirect estimation of the fluoride absorption in different types of water through the assessment of the fractional urinary fluoride excretion of volunteers. Average daily FUFE values (daily amount of fluoride excreted in urine/daily total fluoride intake) were not significantly different between the three treatments (Kruskal-Wallis; p = 0.62). The average 24-hour FUFE value (n=60) was 0.69; 95% C.I. 0.65-0.73. The results of this study suggest that the absorption of fluoride is not affected by water hardness.

A pilot study was designed to determine the general health problems of inner city sex workers. The researchers worked with an agency that provides outreach services to these sex workers. Through this agency, they had access to a purposive sample of sex workers in a large Midwest city. Nonparticipant observation was used to gather information about their health problems, the nature of information they may need, and the barriers to obtaining health care and health information. Sex workers (N = 75) ranged in age from nineteen to sixty-one years old. They identified a number of physical or psychological problems, such as rape, depression, and tuberculosis. HIV/AIDS was never mentioned. A major barrier to health care is a lack of information about where to go for treatment or how to obtain health insurance. More research needs to be done by library and information science professionals to determine the information needs of sex workers and the agencies that provide them with health and social services.

Drug use is often associated with risky and unsafe behavior. However, the acute effects of cocaine and cannabis on performance monitoring processes have not been systematically investigated. The aim of the current study was to investigate how administration of these drugs alters performance monitoring processes, as reflected in the error-related negativity (ERN), the error positivity (Pe) and post-error slowing. A double-blind placebo-controlled randomized three-way crossover design was used. Sixty-one subjects completed a Flanker task while EEG measures were obtained. Subjects showed diminished ERN and Pe amplitudes after cannabis administration and increased ERN and Pe amplitudes after administration of cocaine. Neither drug affected post-error slowing. These results demonstrate diametrically opposing effects on the early and late phases of performance monitoring of the two most commonly used illicit drugs of abuse. Conversely, the behavioral adaptation phase of performance monitoring remained unaltered by the drugs. Copyright © 2016. Published by Elsevier B.V.

Transportation-related injuries are a leading cause of pediatric death, and effective interventions are limited. Otto the Auto is a website offering engaging, interactive activities. We evaluated Otto among a sample of sixty-nine 4- and 5-year-old children, who participated in a randomized parallel group design study. Following baseline evaluation, children engaged with either Otto or a control website for 2 weeks and then were re-evaluated. Children who used Otto failed to show increases in transportation safety knowledge or behavior compared to the control group, although there was a dosage effect whereby children who engaged in the website more with parents gained safer behavior patterns. We conclude Otto may have some efficacy when engaged by children with their parents, but continued efforts to develop and refine engaging, effective, theory-driven strategies to teach children transportation safety, including via internet, should be pursued.

OBJECTIVE: To identify the problems encountered by residents during training and the solutions they proposed. DESIGN: Qualitative study. SETTING: Family practice program at Sherbrooke University. PARTICIPANTS: Sixty-eight residents in the Family practice program between 1999 and 2000. METHOD: We used the nominal group technique with four groups of participants. Then we held five 3-hour discussion groups to explore difficulties and solutions in depth. Finally, data were validated with a written questionnaire. MAIN FINDINGS: At least 20% of respondents confirmed 65 difficulties and 61 solutions. Three major themes emerged: the many demands of the residence program, residents' personal experience of the program, and the lack of time for personal life. CONCLUSION: Publication of these results could help residents develop proactive adaptive strategies to deal with the stress of their training programs. Certain adjustments will be made by the program administration to make it easier for residents to manage their stress. PMID:12729243

The aim of this study was to identify factors influencing compliance with prescribed treatment in patients with chronic heart failure. A qualitative design with a critical incident technique was used. Incidents were collected through interviews with 25 patients with heart failure strategically selected from a primary health care clinic, a medical ward, and a specialist clinic. Two hundred sixty critical incidents were identified in the interviews and 2 main areas emerged in the analysis: inward factors and outward factors. The inward factors described how compliance was influenced by the personality of the patient, the disease, and the treatment. The outward factors described how compliance was influenced by social activities, social relationships, and health care professionals. By identifying the inward and outward factors influencing patients with chronic heart failure, health care professionals can assess whether intervention is needed to increase compliance.

Three domains of analysis emerged: point of reference for the leader (individual, family, community), what a leader is (self-actualized, wise, experienced, political, bicultural, recognized, quiet presence, humble, spiritual, and visionary), and what a leader does (mentors, role models, communicates, listens, demonstrates values, mobilizes, and inspires). Native nurse leaders lead differently. Thus, a leadership curriculum suitable for Native nurses may lead to increased work productivity and therefore improved patient care for Native Americans.

2017-01-01

Background: The extraction of third molars is associated with some clinical outcomes and periodontal problems. It is imperative to note that the type of incision used in the surgery for the removal of the impacted third molar is critical. The design of the flap influences the healing of the surgically created defect and damage to the distal periodontal area of the adjacent second molar. However, till date, there have been conflicting reports on the influence of different flap designs used for the surgical removal of impacted third molars. Aim: The present study aimed to comparatively evaluate the clinical outcomes and periodontal status of the adjacent second molar, when two different flap designs, namely, the envelope and the modified triangular flap designs were used. Materials and Methods: Sixty female patients with bilateral impacted third molars completed the study with envelope flap on one side and modified triangular flap design on the other side of the mandible for third molar removal. Clinical parameters including pain, dehiscence and swelling were assessed postoperatively and periodontal probing depth (PPD) on the distal aspect of adjacent second molar were assessed both pre- and post-operatively. Results: The results were assessed on 1, 3 and 8 days for pain using visual analog scale. The subjective perception of swelling was evaluated on 3, 7 and 15 days postoperatively in a similar manner. The results of the periodontal parameters were evaluated both preoperatively and 3 months postoperatively, with cautious exploration using a University of North Carolina (UNC)-15 periodontal probe. The statistically significant results for swelling and PPD were noted for the two flap groups using the Chi-square test (P < 0.05). Conclusion: The study revealed that the modified triangular flap had lesser postoperative PPDs and dehiscence. The envelope flap was better when swelling was analyzed. The pain scores, though slightly higher for the modified triangular flap group, were not statistically significant. PMID:28932049

Background: Above all methods effective learning results from decent training, acquired in the proper environment and encouraging creative methods. Computer-assisted training by educational software is considered a fundamental measure to improve medical and dentistry education systems. This study aims to design and assess fixed dental prostheses via 2 multimedia instructional contents at the Guilan dentistry school. Methods: This is a descriptive and cross-sectional study. First off, the instructional content was analyzed. The software used to produce multimedia was the iSpring suite Ver.7.0. After designing the instructional multimedia, this software was loaded by LMS. Sixty-nine dentistry students in the 5th semester at Guilan Dentistry School were selected via convenience sampling. At the end of the course, a structured questionnaire containing 26 items were handed to the students to evaluate the instructional multimedia quality. Results: Mean ±SD age was 24.68±3.24 years, 43 were women (62.4%) and 26 were men (37.6%) –the majority of 76.8% used the internet at home. A portion of 33.3% were inclined to use multimedia and the internet with in-person training. About 60% declared that multimedia quality as being good. Conclusion: the instructional multimedia designs which are compatible with lesson objectives and audiovisual facilities can have a great effect on the student's satisfaction. Preparing instructional multimedia makes the instructional content easily accessible for students to be able to review it several times at the proper opportunity and if presented through LMS they would be able to study the lesson subject wherever and whenever accessing the internet.

The SAGES Mini Med School (SMMS) was designed to expose high school students to the field of surgery through mentoring, knowledge transfer, and hands-on experience with simulation. The objective of this paper is to profile the evolutionary development, performance metrics, and satisfaction queries of this innovative effort. Sixty-one high school students, grades 9-12, took part in the (SMMS) program during the 2015 SAGES Annual Congress. The students completed a surgical skills lab session where they attempted tasks associated with the development of open surgical and laparoscopic skills. The lab included a warm-up with the validated Super Monkey Ball video game, Top Gun Pea Drop task, FLS Peg Transfer task, open knot tying station, and open instrument tie station. The following are the results of the surgical skills lab. For the Super Monkey Ball task, 60 students participated with an average score of 73.0 s (SD = 53.9; range 59.1-87.0; median = 74). Sixty students participated in the Surgeons Knot and Pea Drop tasks with average times of 26.6 s (SD = 19.3; range 21.7-31.6; median = 21.0) and 113.8 s (SD = 65.9; range 96.6-131.0; median = 101.0), respectively. Sixty students participated in the Instrument Tie and 56 students participated in the Peg Transfer stations with average times of 51.7 s (SD = 34.5; range 42.8-60.6; median = 39.5) and 173.1 s (SD = 25.0; range 166.4-179.8; median = 180.0), respectively. 51 (83.6%) agreed that the Mini Med School made them more likely to consider a career in medicine. When asked if the program made them more likely to consider a career in surgery 42 (68.8%) agreed. All 61 respondents (100%) said that they would recommend the program to others. The SMMS program showed that the students had an excellent aptitude for the performance of validated surgical subtasks with high satisfaction, and increased consideration of a career in medicine/surgery. Long-term studies are needed to evaluate the impact on workforce recruitment.

2018-01-01

Objectives The aim was to obtain insight into the factors in the work environment that motivate or demotivate a medical specialist during his/her working day. Methods A qualitative ethnographic design was used, and a constructivist approach was adopted with the Self-Determination theory of motivation as a framework. Six medical specialists from VU University Medical Center in the Netherlands, recruited through convenience, snowball, and purposive sampling, were shadowed for one day each. Data were transcribed and open-coded. Themes were finalized through discussion and consensus. Results Sixty hours of observation data identified motivating and demotivating factors categorized into four themes that are important for specialists’ motivation. Informational technology issues are demotivating factors. Working with colleagues can be both a motivating and demotivating factor, e.g., filling in for each other through feelings of relatedness was motivating. Being in control of one’s planning through feelings of autonomy was motivating. Furthermore, patient care and teaching, especially in combination, stimulated specialists’ motivation. Regarding the design of the study, we found that situational motivation is indeed observable. Conclusions The basic psychological needs autonomy, competence, and relatedness are important for specialists’ motivation. Investing in a more motivating, open, transparent, and basic-needs- supportive work environment for medical specialists is necessary. Keywords: Continuing professional development, motivation, medical specialists, self-determination theory, qualitative research. PMID:29485972

Febrile seizure (FS) is the most common problem in pediatric neurology. The purpose of this study was to determine FS recurrence frequency and to evaluate its risk factors. In a descriptive retrospective study, 139 children with first FS, admitted between March 2004 and August 2005 in Yazd Shaheed Sadoughi Hospital, were followed. Seventy-six boys and 63 girls with a mean age of 2.03 +/- 1.21 years were followed for 25.1 +/- 5.5 months. Thirty-seven percent had FS recurrence, with a mean recurrence time of 6.7 +/- 5.9 months. Sixty-five percent of infants and 30% of children >1 year old had FS recurrence. Sixty-three percent of those with seizure occurring in <1 hour of fever duration had FS recurrence, while only 33% of those with seizure after >1 hour of fever duration had FS recurrence. Seizures in children <1 year old and in <1 hour of fever duration were risk factors for FS recurrence.

Cell-mediated immunity to homologous spermatozoa following vasectomy in the human male.

PubMed Central

Nagarkatti, P S; Rao, S S

1976-01-01

Cell-mediated immunity (CMI) to homologous spermatozoal antigens was studied in sixty-two males following vasectomy of a duration of 1-10 years. A group of twenty-two normal, fertile non-vasectomized males was also included in the study. The inhibition in the leucocyte migration test (LMT), in the presence of spermatozoal antigen, was taken as an index of CMI. Twenty of the sixty-two vasectomized males (32.2 percent) showed a positive LMT reaction. When the results were analysed with reference to the duration of vasectomy, it was noted that four cases each (22.2 percent), showed a positive LMT reaction in the groups 0-2 years, and 3.5 years. On the other hand twelve cases gave a positive reaction in the group 6-10 years (46.1 percent). It appears that the incidence of CMI to spermatozoa increases with the duration in vasectomy.

Studies involving jackfruit tree (Artocarpus heterophyllus Lam.) focus on its fruit. Nevertheless a considerable part of jackfruit weight is represented by its seeds. Despite being consumed in several countries, knowledge about the chemical composition of these seeds is scarce. In this work, the accumulation of primary and secondary metabolites in jackfruit seed kernel and seed coating membrane was studied. Sixty-seven compounds were identified, sixty of them being reported for the first time in jackfruit seed. Both tissues had a similar qualitative profile, but significant quantitative differences were found. The capacity of aqueous extracts from jackfruit seed kernel and seed coating membranes to scavenge nitric oxide radical was also evaluated for the first time, the extract prepared from the seed coating membrane being the most potent. This work increases the potential revenue from a food that is still largely wasted. Copyright © 2017 Elsevier Ltd. All rights reserved.

Two studies are presented that evaluated the Communication Supports Inventory-Children & Youth (CSI-CY), an instrument designed to facilitate the development of communication-related educational goals for students with complex communication needs (CCN). The CSI-CY incorporates a code set based on the ICF-CY. The studies were designed to determine the effect of using the CSI-CY on IEP goals for students with CCN and to evaluate consumer satisfaction. In Study 1, sixty-one educators and speech-language pathologists were randomly assigned to either (a) provide a student's current IEP (control group) or (b) complete the CSI-CY prior to preparing a student's next IEP and to submit the new IEP (experimental group). Study 2 was a field test to generate consumer satisfaction data. Study 1 showed that IEP goals submitted by participants in the experimental group referenced CSI-CY-related content significantly more frequently than did those submitted by control participants. Study 2 revealed high satisfaction with the instrument. The code set basis of the CSI-CY extends the common language of the ICF-CY to practical educational use for children with CCN across diagnostic groups. The CSI-CY is well regarded as an instrument to inform the content of communication goals related to CCN. Implications for Rehabilitation The CSI-CY will guide rehabilitation professionals to develop goals for children with complex communication impairments. The CSI-CY is a new instrument that is based on the ICF-CY for documentation of communication goals.

A pulse shape discriminator and an online system for the balloon-borne hard X-ray/gamma-ray detector

Attention is given to a new kind of phoswich counters (the well-type phoswich counter) that will be capable of detecting very low flux hard X-rays/gamma-rays (40-1000 keV) from astronomical objects. A specially designed pulse-shape discriminator (PSD) selects hard X-rays/gamma-rays that has deposited energy only in the detection part. Sixty-four such counters are assembled into an array where each phoswich element acts as an active shield to the neighboring elements too. The ADCs, the TDCs, the hit-pattern latches, and the precision clock are read out by a VME-based online system, stored on an 8-mm video tape, and transmitted to the ground station. The design and performance of the pulse shape discriminator and the online system are described.

Background: This prospective cohort study was designed to determine whether the amount of radiation delivered to the nonpathological lymph nodes (LNs) that drain the arm can be significantly reduced by integrating single-photon emission computed tomography (SPECT)/computed tomography (CT) scans into radiation treatment planning. Methods: SPECT-CT scans were acquired for the 28 patients with stage I or II breast cancer and fused with the routinely obtained radiation oncology planning CT scans. Arm-draining LNs were contoured with 0.5-cm margins automatically using a threshold of 50% maximum intensity. Two treatment plans were generated: 1 per routine clinical practice (standard; STD) and the secondmore » (modified; MOD) with treatment fields modified to minimize dose to the arm-draining LNs visible on SPECT/CT images without interfering with the dosage delivered to target tissues. Participants were treated per the MOD plans. Arm volumes were measured prior to radiation and thereafter at least three subsequent 6-month intervals. Results: Sixty-eight level I-III arm-draining LNs were identified, 57% of which were inside the STD plan fields but could be blocked in the MOD plan fields. Sixty-five percent of arm-draining LNs in the STD versus 16% in the MOD plans received a mean of ≥10 Gy, and 26% in the STD versus 4% in the MOD plans received a mean of ≥40 Gy. Mean LN radiation exposure was 23.6 Gy (standard deviation 18.2) with the STD and 7.7 Gy (standard deviation 11.3) with the MOD plans (P<.001). No participant developed lymphedema. Conclusions: The integration of SPECT/CT scans into breast cancer radiation treatment planning reduces unnecessary arm-draining LN radiation exposure and may lessen the risk of lymphedema.« less

Sixty-five percent of arm-draining LNs in the STD versus 16% in the MOD plans received a mean of ≥10 Gy, and 26% in the STD versus 4% in the MOD plans received a mean of ≥40 Gy. Mean LN radiation exposure was 23.6 Gy (standard deviation 18.2) with the STD and 7.7 Gy (standard deviation 11.3) with the MOD plans (P<.001). No participant developed lymphedema. The integration of SPECT/CT scans into breast cancer radiation treatment planning reduces unnecessary arm-draining LN radiation exposure and may lessen the risk of lymphedema.

People with vestibular disorders report changes in symptoms based on their environment with many situations increasing their symptoms. The purpose of this paper was to utilize the International Classification of Functioning Disability and Health (ICF) from the World Health Organization (WHO) to describe common environmental triggers for dizziness in persons living with balance and vestibular disorders. A multi-centre cross-sectional study was conducted with four different centres on three different continents, including patients from the United States (Pittsburgh), Germany (Munich), Jordan (Amman) and Saudi Arabia (Riyadh). Three hundred eighty one persons with vestibular disorders participated. A 9-item questionnaire (the Vestibular Environmental Scale) was developed from existing ICF items, which were compared to Dizziness Handicap Inventory (DHI) scores. Sixty-five percent of participants reported that "quick movements in the vicinity" increased symptoms, "crowds" at 45%, and "design of buildings, e.g. narrow hallways, stairs, elevators" at 42%. The "crowds" item was a good positive predictor of psychogenic vertigo (OR 1.8, 95% Confidence Interval 1.03-3.16), while "food" (OR 0.47, 95% Confidence Interval 0.17-1.29) and "light" (OR 0.41 95% Confidence Interval 0.23-0.75) were negative predictors of psychogenic vertigo. There also was a positive correlation between the number of triggers and DHI score (Spearman correlation coefficient 0.47, p < 0.0001). Sixty-eight percent of the subjects reported an increase in symptoms with between 1 and 4 environmental triggers. In our cross cultural sample, environmental triggers affect dizziness in persons living with balance and vestibular disorders. The use of items from the ICF of the WHO may help to promote cross cultural sharing of information in persons with dizziness.

Few studies have assessed the role of cross-sex hormones on psychological outcomes during the period of hormonal therapy preceding sex reassignment surgery in transsexuals. The objective of this study was to assess the relationship between hormonal therapy, self-esteem, depression, quality of life (QoL), and global functioning. This study incorporated a cross-sectional design. The inclusion criteria were diagnosis of gender identity disorder (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision) and inclusion in a standardized sex reassignment procedure. The outcome measures were self-esteem (Social Self-Esteem Inventory), mood (Beck Depression Inventory), QoL (Subjective Quality of Life Analysis), and global functioning (Global Assessment of Functioning). Sixty-seven consecutive individuals agreed to participate. Seventy-three percent received hormonal therapy. Hormonal therapy was an independent factor in greater self-esteem, less severe depression symptoms, and greater "psychological-like" dimensions of QoL. These findings should provide pertinent information for health care providers who consider this period as a crucial part of the global sex reassignment procedure.

2013-01-01

The aim of this study was to analyze the practical skills of rhythmic gymnastics judges and to identify how their degree and experience influence the assessment of these skills. Sixty one rhythmic gymnastics judges participated in the study. A questionnaire was used for data collection. This tool was composed of 28 questions and divided into six categories: identification, experience, initial training, continuing education, skills and training needs. The results suggest that the most valued skills are those related to the sport’s technical parameters and the ability to adapt to any level of competition with self-confidence and self-assuredness. Significant differences were found regarding the variables for: the ability to communicate (p = 0.002) and for the ability to observe, identify and register performance (p = 0.005). The results showed that experience was not a decisive factor in assessing skills. This study thus presents evidence that rhythmic gymnastics judges must implement and optimise a set of skills that contribute to the effectiveness of the assessment process. These findings might help in the design of programs and training models that contribute to effective professional development. PMID:24511360

The strategy of using multiple versions of independently developed software as a means to tolerate residual software design faults is suggested by the success of hardware redundancy for tolerating hardware failures. Although, as generally accepted, the independence of hardware failures resulting from physical wearout can lead to substantial increases in reliability for redundant hardware structures, a similar conclusion is not immediate for software. The degree to which design faults are manifested as independent failures determines the effectiveness of redundancy as a method for improving software reliability. Interest in multi-version software centers on whether it provides an adequate measure of increased reliability to warrant its use in critical applications. The effectiveness of multi-version software is studied by comparing estimates of the failure probabilities of these systems with the failure probabilities of single versions. The estimates are obtained under a model of dependent failures and compared with estimates obtained when failures are assumed to be independent. The experimental results are based on twenty versions of an aerospace application developed and certified by sixty programmers from four universities. Descriptions of the application, development and certification processes, and operational evaluation are given together with an analysis of the twenty versions.

Generic drug names and social welfare.

PubMed

Lobo, Félix; Feldman, Roger

2013-06-01

This article studies how well International Nonproprietary Names (INNs), the "generic" names for pharmaceuticals, address the problems of imperfect information. Left in private hands, the identification of medicines leads to confusion and errors. Developed in the 1950s by the World Health Organization, INNs are a common, global, scientific nomenclature designed to overcome this failure. Taking stock after sixty years, we argue that the contribution of INNs to social welfare is paramount. They enhance public health by reducing errors and improving patient safety. They also contribute to economic efficiency by creating transparency as the foundation of competitive generic drug markets, reducing transaction costs, and favoring trade. The law in most countries requires manufacturers to designate pharmaceuticals with INNs in labeling and advertising. Generic substitution is also permitted or mandatory in many countries. But not all the benefits of INNs are fully realized because prescribers may not use them. We advocate strong incentives or even legally binding provisions to extend the use of INNs by prescribing physicians and dispensing pharmacists, but we do not recommend replacing brand names entirely with INNs. Instead, we propose dual use of brand names and INNs in prescribing, as in drug labeling.

Interventions using high-technology communication devices: a state of the art review.

2012-01-01

In the last 20 years the range of high-technology augmentative and alternative communication (AAC) aids has rapidly expanded. This review aimed to provide a 'state of the art' synthesis, to provide evidence-based information for researchers, potential users and service providers. Electronic databases were searched from 2000 to 2010, together with reference lists of included papers and review papers. The review considered work of any design which reported an intervention using high-tech AAC with people who have communication difficulties (excluding those with solely hearing or visual loss) published in peer-reviewed journals. Sixty-five papers reporting interventions using high-tech AAC were identified. There was evidence that high-technology AAC may be beneficial across a range of diagnoses and ages. The evidence, however, is currently drawn from studies using designs considered to be at high risk of bias. The review suggests that the high level of individual variation in outcome requires a greater understanding of characteristics of clients who may or may not benefit from this technology. Also, the wide range of outcomes measured requires further work in the field to establish what a 'good outcome' from intervention may be. Copyright © 2012 S. Karger AG, Basel.

Onion bulbs can become contaminated with various molds during the storage period, the most important causal agents being black aspergilli (Aspergillus section Nigri). Taxonomic studies have revealed that this group of Aspergillus contains many species that cannot be reliably identified using standard morphological methods. Therefore, it is necessary to define the fungus causing this problem in the onion exactly, especially since some species assigned to section Nigri are well known as ochratoxin and/or fumonisin producers. Sixty fungal isolates belonging to 10 fungal genera were isolated from 40 onion samples originated from the Taif region in Saudi Arabia. Black aspergilli were detected in 37 onion samples. Using primer pairs (awaspec and Cmd6) designed based on partial calmodulin gene sequence data, 37 isolates were identified as A. welwitschiae. The ochratoxin A and fumonisin B2 contents of the onion samples were examined. No ochratoxins were detected in the collected samples, while fumonisin B2 was detected in 37.5% of the onion samples. Eighteen of 37 isolates of Aspergillus welwitschiae were recognized as potential producers for fumonisin B2. Multiplex polymerase chain reactions designed to detect biosynthetic genes of fumonisins confirmed these results.

The aim of this study was to explore the effect of single-dose albendazole and vitamin A intervention on the anaemic status and Fe metabolism of pre-school children. This study was a randomised, placebo-controlled and double-blinded intervention trial. All eligible anaemic pre-school children were randomly divided into three groups: group 1 received no intervention, which served as the control group, group 2 received 400 mg single-dose albendazole administration and group 3 received a 60000 μg vitamin A capsule combined with 400 mg single-dose albendazole at the beginning of the study. The follow-up period was for 6 months. Anthropometry and biochemical index about Fe metabolism were measured before and after intervention. A total of 209 pre-school anaemic children were randomly divided into three intervention groups (sixty-four, sixty-two and sixty for groups 1, 2 and 3, respectively). The mean age of the children in the study was 4·4 (sd 0·7) years and 50·5 % of the children were female (94/186). After a follow-up period of 6 months, the levels of serum retinol, ferritin, transferrin receptor-ferritin index and body total Fe content of children in group 3 were significantly higher compared with children in groups 1 and 2 (P<0·05). Moreover, the proportion of vitamin A deficiency, marginal vitamin A deficiency and Fe deficiency among children in group 3 were markedly lower compared with children in groups 1 and 2 (P<0·05). Albendazole plus vitamin A administration showed more efficacy on the improvement of serum retinol and Fe metabolic status.

The High Luminosity LHC (HL-LHC) is a project to upgrade the LHC collider after 2020-2025 to increase the integrated luminosity by about one order of magnitude and extend the physics production until 2035. An upgrade of the focusing triplets insertion system for the ATLAS and CMS experiments is foreseen using superconducting magnets operating in a pressurised superfluid helium bath at 1.9 K. This will require the design and construction of four continuous cryostats, each about sixty meters in length and one meter in diameter, for the final beam focusing quadrupoles, corrector magnets and beam separation dipoles. The design is constrained by the dimensions of the existing tunnel and accessibility restrictions imposing the integration of cryogenic piping inside the cryostat, thus resulting in a very compact integration. As the alignment and position stability of the magnets is crucial for the luminosity performance of the machine, the magnet support system must be carefully designed in order to cope with parasitic forces and thermo-mechanical load cycles. In this paper, we present the conceptual design of the cryostat and discuss the approach to address the stringent and often conflicting requirements of alignment, integration and thermal aspects.

Diabetes mellitus II (DM II) is a newly defined independent factor contributing to the morbidity and mortality of cryptococcosis. This retrospective case analysis aims to explore the epidemiology, clinical profile and strain characteristics of cryptococcosis in Chinese DM II patients. This study included 30 cases of cryptococcosis with DM II occurring from 1993 to 2015 in mainland China. The hospital-based prevalence of cryptococcosis in DM II was 0.21%. The mean age of the patients was 56.1 years (95% confidence interval: 51.5, 60.6), and 93% of the patients were older than 40 years. Sixty-two per cent of the patients experienced untreated or poorly controlled blood glucose before infection. Multilocus sequence typing analysis categorised all cultured strains as Cryptococcus neoformans and sequence type 5. Sixty-nine per cent of pulmonary cryptococcosis patients experienced misdiagnoses and treatment delays. Sixty per cent of cryptococcal meningitis patients received substandard antifungal therapy. The overall death rate was 33%. Considering the large population size of DM II patients in China, improved attention should be paid to the high prevalence of cryptococcosis as revealed by us. We also emphasised the importance of blood glucose control for infection prevention, especially among the elderly. © 2017 Blackwell Verlag GmbH.

Background Vestibular and ocular motor impairments and symptoms have been documented in patients with sport-related concussions. However, there is no current brief clinical screen to assess and monitor these issues. Purpose To describe and provide initial data for the internal consistency and validity of a brief clinical screening tool for vestibular and ocular motor impairments and symptoms after sport-related concussions. Study Design Cross-sectional study; Level of evidence, 2. Methods Sixty-four patients, aged 13.9 ± 2.5 years and seen approximately 5.5 ± 4.0 days after a sport-related concussion, and 78 controls were administered the Vestibular/Ocular Motor Screening (VOMS) assessment, which included 5 domains: (1) smooth pursuit, (2) horizontal and vertical saccades, (3) near point of convergence (NPC) distance, (4) horizontal vestibular ocular reflex (VOR), and (5) visual motion sensitivity (VMS). Participants were also administered the Post-Concussion Symptom Scale (PCSS). Results Sixty-one percent of patients reported symptom provocation after at least 1 VOMS item. All VOMS items were positively correlated to the PCSS total symptom score. The VOR (odds ratio [OR], 3.89; P <.001) and VMS (OR, 3.37; P <.01) components of the VOMS were most predictive of being in the concussed group. An NPC distance ≥5 cm and any VOMS item symptom score ≥2 resulted in an increase in the probability of correctly identifying concussed patients of 38% and 50%, respectively. Receiver operating characteristic curves supported a model including the VOR, VMS, NPC distance, and ln(age) that resulted in a high predicted probability (area under the curve = 0.89) for identifying concussed patients. Conclusion The VOMS demonstrated internal consistency as well as sensitivity in identifying patients with concussions. The current findings provide preliminary support for the utility of the VOMS as a brief vestibular/ocular motor screen after sport-related concussions. The VOMS may augment current assessment tools and may serve as a single component of a comprehensive approach to the assessment of concussions. PMID:25106780

1What do first-time mothers worry about? A study of usage patterns and content of calls made to a postpartum support telephone hotline

2010-01-01

Background Telephone hotlines designed to address common concerns in the early postpartum could be a useful resource for parents. Our aim was to test the feasibility of using a telephone as an intervention in a randomized controlled trial. We also aimed to test to use of algorithms to address parental concerns through a telephone hotline. Methods Healthy first-time mothers were recruited from postpartum wards of hospitals throughout Lebanon. Participants were given the number of a 24-hour telephone hotline that they could access for the first four months after delivery. Calls were answered by a midwife using algorithms developed by the study team whenever possible. Callers with medical complaints were referred to their physicians. Call patterns and content were recorded and analyzed. Results Eighty-four of the 353 women enrolled (24%) used the hotline. Sixty percent of the women who used the service called more than once, and all callers reported they were satisfied with the service. The midwife received an average of three calls per day and most calls occurred during the first four weeks postpartum. Our algorithms were used to answer questions in 62.8% of calls and 18.6% of calls required referral to a physician. Of the questions related to mothers, 66% were about breastfeeding. Sixty percent of questions related to the infant were about routine care and 23% were about excessive crying. Conclusions Utilization of a telephone hotline service for postpartum support is highest in the first four weeks postpartum. Most questions are related to breastfeeding, routine newborn care, and management of a fussy infant. It is feasible to test a telephone hotline as an intervention in a randomized controlled trial. Algorithms can be developed to provide standardized answers to the most common questions. PMID:20946690

2016-09-01

Among the rich material of chondrichthyan microremains from the Indian Cave Sandstone (Upper Pennsylvanian, Gzhelian) near Peru, Nebraska, USA, housed at the Carnegie Museum of Natural History, there occur almost sixty teeth representing Euselachii. They belong to at least seven species, presenting various types of heterodonty. Two new species are described, viz. Ossianodus nebraskensis gen. et sp. nov., whose dentition is similar to that of certain Mesozoic hybodonts, and Sphenacanthus tenuis sp. nov. with minute teeth of protacrodont design. Most of the euselachian teeth served to crush or grind prey, and some had the potential to clutch, but cutting teeth are absent from the fauna.

2013-01-01

Although awareness of sleep disorders is increasing, limited information is available on whole night detection of snoring. Our study aimed to develop and validate a robust, high performance, and sensitive whole-night snore detector based on non-contact technology. Sounds during polysomnography (PSG) were recorded using a directional condenser microphone placed 1 m above the bed. An AdaBoost classifier was trained and validated on manually labeled snoring and non-snoring acoustic events. Sixty-seven subjects (age 52.5 ± 13.5 years, BMI 30.8 ± 4.7 kg/m(2), m/f 40/27) referred for PSG for obstructive sleep apnea diagnoses were prospectively and consecutively recruited. Twenty-five subjects were used for the design study; the validation study was blindly performed on the remaining forty-two subjects. To train the proposed sound detector, >76,600 acoustic episodes collected in the design study were manually classified by three scorers into snore and non-snore episodes (e.g., bedding noise, coughing, environmental). A feature selection process was applied to select the most discriminative features extracted from time and spectral domains. The average snore/non-snore detection rate (accuracy) for the design group was 98.4% based on a ten-fold cross-validation technique. When tested on the validation group, the average detection rate was 98.2% with sensitivity of 98.0% (snore as a snore) and specificity of 98.3% (noise as noise). Audio-based features extracted from time and spectral domains can accurately discriminate between snore and non-snore acoustic events. This audio analysis approach enables detection and analysis of snoring sounds from a full night in order to produce quantified measures for objective follow-up of patients.

Multimorbidity and unmet citizens’ needs and expectations urge for reforms in the health system of Cyprus: a questionnaire survey

Theodosopoulou, Eleni; Papanastasiou, Elena

2014-01-01

Objective This study aims to investigate the prevalence of multimorbidity in Cyprus and the extent to which citizens are satisfied with the currently provided healthcare and to provide recommendations on the basis of findings. Design A nationally based survey conducted through personal interviews, using a structured questionnaire designed for this survey. Setting Cyprus rural and urban areas (excluding Turkish occupied areas). Participants Four hundred and sixty-five Cypriot adults, average age 53 years. Main outcome measures Lifetime prevalence of self-reported non-communicable diseases. Results This study demonstrated initial evidence for a high prevalence of non-age specific multimorbidity among Cypriots and dissatisfaction with their doctors, especially for the time allocated to discuss their general state of health. Recommendations focus on a new cost-effective, person-centred model of healthcare. The model prioritizes prevention rather than treatment, targeting the determinants of complexity before their influences create conditions that demand high-cost interventions, and it is based on three fundamental principles: (1) tackling health as a political issue, (2) empowering the patient and (3) introducing Applied Nutrition in the system. Conclusions This study threw light into the issue of patient complexity and revealed unmet people’s needs and expectations for a more person-centred care, providing a first challenge to the single disease-based system of healthcare in Cyprus. The findings of the study may have important implications for government policies and highlight the need for more research in this area to inform policy makers, particularly in view of the fact that a new Health System is currently being designed.

Burke, Emily E.; Holmes, Shannon P.

2017-01-01

Objectives The purpose of this study was to investigate whether platelet-rich plasma (PRP) enhances osseous healing in conjunction with a high tibial osteotomy in dogs. Study design Randomized controlled trial. Methods Sixty-four client-owned pet dogs with naturally occurring rupture of the anterior cruciate ligament and that were to be treated with a high tibial osteotomy (tibial plateau leveling osteotomy) were randomized into the treatment or control group. Dogs in the treatment group received autologous platelet-rich plasma activated with calcium chloride and bovine thrombin to produce a well-formed PRP gel that was placed into the osteotomy at the time of surgery. Dogs in the control group received saline lavage of the osteotomy. All dogs had the osteotomy stabilized with identical titanium alloy implants and all aspects of the surgical procedure and post-operative care were identical among dogs of the two groups. Bone healing was assessed at exactly 28, 49, and 70 days after surgery with radiography and ultrasonography and with MRI at day 28. The effect of PRP on bone healing was assessed using a repeated measures analysis of covariance with radiographic and ultrasonographic data and using a t-test with the MRI data. Results Sixty dogs completed the study. There were no significant differences in age, weight, or gender distribution between the treatment and control groups. Twenty-seven dogs were treated with PRP and 33 were in the control group. The average platelet concentration of the PRP was 1.37x106 platelets/μL (±489x103) with a leukocyte concentration of 5.45x103/μL (±3.5x103). All dogs demonstrated progressive healing over time and achieved clinically successful outcomes. Time since surgery and patient age were significant predictors of radiographic healing and time since surgery was a significant predictor of ultrasonographic assessment of healing. There was no significant effect of PRP treatment as assessed radiographically, ultrasonographically, or with MRI. Conclusion The PRP used in this study did not hasten osseous union in dogs treated with a high tibial osteotomy. PMID:28520812

Objective: Small uncontrolled series suggest that treatment of obstructive sleep apnea (OSA) in patients with epilepsy may improve seizure control. Prior to conducting a definitive randomized controlled trial, we addressed critical design issues in a pilot study. Methods: We identified a cohort of adult patients with medically refractory epilepsy and coexisting OSA, documented by polysomnography (PSG). After an 8-week baseline period, subjects with OSA were randomized to therapeutic or sham continuous positive airway pressure (CPAP) for 10 weeks. Subjects maintained seizure calendars and antiepileptic drug dosages were held constant. Results: Sixty-eight subjects with suspected OSA were enrolled and 35 subjects randomized to therapeutic CPAP (22 subjects) or sham (13 subjects) CPAP. Male gender and an elevated sleep apnea questionnaire score were predictive of OSA on PSG. Nineteen subjects in the therapeutic group and all 13 subjects in the sham group completed the trial. Baseline apnea-hypopnea index (AHI) and CPAP adherence were comparable between groups. A significant reduction in AHI was observed in the therapeutic CPAP group as compared to the sham group. Subjects, study coordinators, and principal investigators were unable to predict treatment allocation. Conclusions: This pilot study provided critical information related to study design and feasibility for planning a comprehensive trial to test the hypothesis that treating obstructive sleep apnea in patients with epilepsy improves seizure control. GLOSSARY AEDs = antiepileptic drugs; AHI = apnea-hypopnea index; BMI = body mass index; CPAP = continuous positive airway pressure; OSA = obstructive sleep apnea; PSG = polysomnography.

2015-03-01

Several studies have suggested that cognitive training is a potentially effective way to improve cognition and postpone cognitive decline in older adults with mild cognitive impairment (MCI). The MEMO+ study is a randomized, controlled, single-blind trial designed to test the efficacy, specificity, and long-term effect of a cognitive training intervention and a psychosocial intervention in persons with MCI. One hundred and sixty-two participants with MCI will be recruited. They will be randomized into three groups: cognitive training, psychosocial intervention, and no-contact. Each intervention will last for eight weeks (one session per week) and a booster training session will be provided three months after the end of the intervention. Various proximal and distal outcomes will be measured at pre-intervention as well as at one week, three months, and six months post-training. Proximal outcomes include memory and psychological health measures. Distal outcomes focus on self-rated functioning in complex daily activities and strategies used in daily life to enhance function. Socio-demographic factors (age, gender, and education), general cognition, personality traits, engagement in activities, and self-efficacy will be used as moderators. Enrolment began in April 2012 and will be completed by December 2014. This study is likely to have a significant impact on the well-being of persons with MCI by contributing to the development of adapted and scientifically supported cognitive and psychosocial interventions.

Bernard J. Cigrand, DDS: Father of Flag Day and renaissance man.

Spiegel, Allen D; Kavaler, Florence

2007-06-01

Dr. Bernard J. Cigrand is acknowledged as the "Father of Flag Day." He relentlessly continued his activities for more than sixty years to have June 14 designated for the national observance of the birth of the American flag. That finally occurred in 1948, seventeen years after his death, when President Harry S. Truman signed a Congressional Act into law. However, the law designated a voluntary observance but did not create a legal national holiday. In addition to his fervent passion for Flag Day, Cigrand undertook a variety of other initiatives He was a practicing dentist, the dean of a dental school, an investigative journalist, an expert on heraldry and seals, a lecturer and an author of books. Despite all his achievements, Cigrand is more widely known in the European country from where his parents emigrated to the United States in 1852 - Luxembourg, than in the United States.

Using open captions to revise writing in digital stories composed by d/Deaf and hard of hearing students.

PubMed

Strassman, Barbara K; O'Dell, Katie

2012-01-01

Using a nonexperimental design, the researchers explored the effect of captioning as part of the writing process of individuals who are d/Deaf and hard of hearing. Sixty-nine d/Deaf and hard of hearing middle school students composed responses to four writing-to-learn activities in a word processor. Two compositions were revised and published with software that displayed texts as captions to digital images; two compositions were revised with a word processor and published on paper. Analysis showed increases in content-area vocabulary, text length, and inclusion of main ideas and details for texts revised in the captioning software. Given the nonexperimental design, it is not possible to determine the extent to which the results could be attributed to captioned revisions. However, the findings do suggest that the images acted as procedural facilitators, triggering recall of vocabulary and details.

1997-01-01

In 1988, the Iowa Department of Natural Resources, along with the University of Iowa conducted the Statewide Rural Well Water Survey, commonly known as SWRL. A total of 686 private rural drinking water wells was selected by use of a probability sample and tested for pesticides and nitrates. Sixty-eight of these wells, the '10% repeat' wells, were additionally sampled in October, 1990 and June, 1991. Starting in November, 1991, the University of Iowa, with sponsorship from the United States Environmental Protection Agency, revisited these wells to begin a study of the temporal variability of atrazine and nitrates in wells. Other wells, which had originally tested positive for atrazine in SWRL but were not in the 10% repeat population, were added to the study population. Temporal sampling for a year-long period began in February of 1992 and concluded in January of 1993. All wells were sampled monthly, one subset was sampled weekly, and a second subset was sampled for 14-day consecutive periods. Two unique aspects of this study were the use of an immunoassay technique to screen for triazines before gas chromatography/mass spectrometry (GC/MS) analysis and quantification of atrazine, and the use of well owners to sample the wells. A total of 1771 samples from 83 wells are in the final data base for this study. This paper reviews the study design, the analytical methodologies, and development of the data base. A companion paper discusses the analysis of the data from this survey.

How Do Clinical Information Systems Affect the Cognitive Demands of General Practitioners?: Usability Study with a Focus on Cognitive Workload.

PubMed

Ariza, Ferran; Kalra, Dipak; Potts, Henry Ww

2015-11-20

Clinical information systems in the National Health Service do not need to conform to any explicit usability requirements. Poor usability can increase the mental workload experienced by clinicians and cause fatigue, increase error rates and impact the overall patient safety. Mental workload can be used as a measure of usability. To assess the subjective cognitive workload experienced by general practitioners (GPs) with their systems. To raise awareness of the importance of usability in system design among users, designers, developers and policymakers. We used a modified version of the NASA Task Load Index, adapted for web. We developed a set of common clinical scenarios and computer tasks on an online survey. We emailed the study link to 199 clinical commissioning groups and 1,646 GP practices in England. Sixty-seven responders completed the survey. The respondents had spent an average of 17 years in general practice, had experience of using a mean of 1.5 GP computer systems and had used their current system for a mean time of 6.7 years. The mental workload score was not different among systems. There were significant differences among the task scores, but these differences were not specific to particular systems. The overall score and task scores were related to the length of experience with their present system. Four tasks imposed a higher mental workload on GPs: 'repeat prescribing', 'find episode', 'drug management' and 'overview records'. Further usability studies on GP systems should focus on these tasks. Users, policymakers, designers and developers should remain aware of the importance of usability in system design.What does this study add?• Current GP systems in England do not need to conform to explicit usability requirements. Poor usability can increase the mental workload of clinicians and lead to errors.• Some clinical computer tasks incur more cognitive workload than others and should be considered carefully during the design of a system.• GPs did not report overall very high levels of subjective cognitive workload when undertaking common clinical tasks with their systems.• Further usability studies on GP systems should focus on the tasks incurring higher cognitive workload.• Users, policymakers, and designers and developers should remain aware of the importance of usability in system design.

A meta-analysis of the effects of measuring theory of planned behaviour constructs on behaviour within prospective studies.

Mankarious, Evon; Kothe, Emily

2015-01-01

Measurement reactivity effects, such as the mere measurement effect, have been proposed as a reason for behavioural changes in a number of theory of planned behaviour intervention studies. However, it is unclear whether such changes are the result of the mere measurement effect or of other artefacts of intervention study design. The aim of this study is to determine the size and direction of changes in health behaviours from baseline to follow-up in prospective studies using the theory of planned behaviour. Electronic databases were searched for the theory of planned behaviour studies which measured health behaviours at two or more time points. Change in behaviour was calculated for all studies. Sixty-six studies were included. Mean effect sizes across all studies were small and negative (d = -.03). Effect size was moderated by behaviour, behaviour type and follow-up length. Subgroup analyses showed significant decreases in socially undesirable behaviour (d = -.28), binge drinking (d = -.17), risk driving (d = -.20), sugar snack consumption (d = -.43) and sun-protective behaviour (d = -.18). Measurement of intention at baseline resulted in significant decreases in undesirable behaviour. Changes in undesirable behaviours reported in other studies may be the result of the mere measurement effect.

How short are ultra short light pulses? (looking back to the mid sixties)

NASA Astrophysics Data System (ADS)

Weber, H. P.; Dändliker, R.

2010-09-01

With the arrival of mode locking for Q-switched lasers to generate ultra short light pulses, a method to measure their expected time duration in the psec range was needed. A novel method, based on an intensity correlation measurement using optical second harmonic generation, was developed. Other reported approaches for the same purpose were critically analysed. Theoretical and subsequent experimental studies lead to surprising new insight into the ultra fast temporal behaviour of broadband laser radiation: Any non mode locked multimode emission of a laser consists of random intensity fluctuations with duration of the total inverse band width of emitted radiation. However, it was shown, that with mode locking isolated ultra short pulses of psec duration can be generated. This article summarizes activities performed in the mid sixties at the University of Berne, Switzerland.

2012-10-01

The object of this study was to determine if early cranioplasty after decompressive craniectomy for elevated intracranial pressure in children reduces complications. Sixty-one consecutive cases involving pediatric patients who underwent autologous cranioplasty after decompressive craniectomy for raised intracranial pressure at a single academic children's hospital over 15 years were studied retrospectively. Sixty-one patients were divided into early (< 6 weeks; 28 patients) and late (≥ 6 weeks; 33 patients) cranioplasty cohorts. The cohorts were similar except for slightly lower age in the early (8.03 years) than the late (10.8 years) cranioplasty cohort (p < 0.05). Bone resorption after cranioplasty was significantly more common in the late (42%) than the early (14%) cranioplasty cohort (p < 0.05; OR 5.4). No other complication differed in incidence between the cohorts. After decompressive craniectomy for raised intracranial pressure in children, early (< 6 weeks) cranioplasty reduces the occurrence of reoperation for bone resorption, without altering the incidence of other complications.

This study investigated oral and parenteral antimicrobial use in dogs and cats, and evaluated antimicrobial use in feline upper respiratory tract disease (FURTD), feline lower urinary tract disease (FLUTD), and canine infectious tracheobronchitis. Study journals (n = 1807) were submitted by 84 veterinarians. Sixty-five percent of the antimicrobials prescribed in dogs and 67% in cats were β-lactams. Most frequently prescribed in dogs were cephalexin (33%) and amoxicillin-clavulanic acid (16%), and in cats, amoxicillin-clavulanic acid (40%) and cefovecin (17%); 7% of the prescriptions in dogs and 12% in cats were for fluoroquinolones. Sixty-seven percent of the disease events associated with canine infectious tracheobronchitis, and 70% and 74% associated with FURTD and FLUTD, respectively, were treated with antimicrobials. These results suggest that cefovecin and fluoroquinolones may be over-used and antimicrobial use for the treatment of FURTD, FLUTD, and canine infectious tracheobronchitis could probably be reduced to lessen resistance selection pressure without compromising patient health.

2006-01-28

To determine in detail the complications associated with the use of mandibular repositioning splints (MRS) to treat sleep-related breathing disorders. This prospective cross-sectional cohort study audits the management with mandibular repositioning splints of 121 patients suffering from sleep-related breathing disorders. Investigation of patients' and sleeping partners' perspectives on treatment was undertaken with the use of a questionnaire based study. Sixty-eight per cent of respondents reported that they were compliant with treatment; various side effects were reported of which excess salivation was the most common. Investigation of sleeping partners' perspectives revealed that 70% felt that their partners' snoring was improved and 47% felt that their partner's breathing pauses during sleep were reduced. Sixty-four per cent of the sleeping partners also reported that their own sleep pattern had improved since their partner's treatment. Mandibular repositioning splints used in the manner described by this paper are demonstrated to have a good compliance rate, provide successful treatment and exhibit only minor, reversible side effects.

OUTCOME MEASURES (3-4 months) Primary: Roland Morris Disability Questionnaire (RMDQ); worst pain in past two weeks. Secondary: Aberdeen Low Back Pain Scale; straight leg raise test; structural changes. Disc projections per case ranged from one bulge or one extrusion to three bulges plus two extrusions. Sixty-two percent had sciatica. Intention-to-treat analysis of the RMDQ data, adjusted for age, sex and baseline RMDQ scores, gave a Yoga Group score 3.29 points lower than Control Group (0.98, 5.61; p=0.006) at 3 months. No other significant differences in the endpoints occurred. No adverse effects of yoga were reported. Yoga therapy can be safe and beneficial for patients with nsLBP or sciatica, accompanied by disc extrusions and bulges.

While Ayurvedic medicine has touted the cognitive enhancing effects of Bacopa monniera for centuries, there is a need for double-blind placebo-controlled investigations. One hundred and seven healthy participants were recruited for this double-blind placebo-controlled independent group design investigation. Sixty-two participants completed the study with 80% treatment compliance. Neuropsychological testing using the Cognitive Drug Research cognitive assessment system was conducted at baseline and after 90 days of treatment with a special extract of Bacopa monniera (2 x 150 mg KeenMind) or placebo. The Bacopa monniera product significantly improved performance on the 'Working Memory' factor, more specifically spatial working memory accuracy. The number of false-positives recorded in the Rapid visual information processing task was also reduced for the Bacopa monniera group following the treatment period. The current study provides support for the two other published studies reporting cognitive enhancing effects in healthy humans after a 90 day administration of the Bacopa monniera extract. Further studies are required to ascertain the effective dosage range, the time required to attain therapeutic levels and the effects over a longer term of administration.

The Limberg flap (LF) procedure is widely performed for the treatment of sacrococcygeal pilonidal sinus (SPS); however, recurrences continues to be observed. The aim of this study was to assess the relationship between LF designs and the risk of SPS recurrence. Sixty-one cases with recurrent disease (study group) and 194 controls, with a minimum of 5 recurrence-free years following surgery (control group), were included in the study. LF reconstructions performed in each group were classified as off-midline closure (OMC) and non-OMC types. Subsequently, the 2 groups were analyzed. After adjustment for all variables, non-OMC types showed the most prominent correlation with recurrence, followed by interrupted suturing type, family history of SPS, smoking, prolonged healing time, and younger age. The best cut-off value for the critical distance from the midline was found to be 11 mm (with 72% sensitivity and 95% specificity for recurrence). We recommend OMC modifications, with the flap tailored to create a safe margin of at least 2 cm between the flap borders and the midline. Copyright © 2017 Elsevier Inc. All rights reserved.

To explore the barriers to requesting social and healthcare assistance perceived by transgender persons and professionals involved in the assistance. A meta-study, qualitative systematic review, of studies published in English or Spanish, exploring the barriers, perceived by transgender persons and social and healthcare professionals, that transgender persons have when they seek social and healthcare assistance was carried out in the following databases Medline (PubMed), Scopus, Web of Science, Spanish National Research Council, CUIDEN, ProQuest, PsycINFO and CINAHL. Two thousand two hundred and sixty-one articles were found in the databases searched. Seven articles met all inclusion criteria and were included in this review. The professionals highlight the uncertainty when treating transgender persons and their lack of training. Transgender persons highlight the lack of information and the sense of helplessness it creates.

Rollerblading in children: the Edinburgh experience.

PubMed Central

McGrath, D; Beattie, T F

1996-01-01

OBJECTIVE: To determine the incidence and severity of injuries sustained by children who present to an accident and emergency (A&E) department following rollerblading accidents. DESIGN: A prospective case-control study. SETTING: The A&E department of a city centre paediatric teaching hospital. METHODS: Data were collected on a specially designed proforma on each child presenting with an injury sustained while rollerblading. The injury severity score was calculated for each patient and details were taken of the length of admission or outpatient follow up where appropriate. RESULTS: Seventy four children (37 male; 37 female) presented with injuries over a three month period. The age range was 6-13 years in both groups. Half the injuries occurred at weekends. Fractures (n = 37) and soft tissue injuries (n = 28) were the most prevalent; 89% of injuries involved the limbs. Sixty eight children (92%) required treatment in A&E. Four (3%) were admitted to hospital and required operative procedures under general anaesthetic. The injury severity score ranged from 1 to 9 with a mean of 2.8. The length of hospital stay for admissions was 1-3 days; 47 children required follow up in the outpatient department (1-3 visits). Average length of outpatient contact was 18 days. CONCLUSIONS: This study shows a greater incidence of rollerblading injuries than has been reported elsewhere. No figures are at present available for the United Kingdom as a whole. PMID:8894866

Objective: The aim of this study was to investigate the effect of cavity design and the type of pulp capping materials on the fracture resistance of Class II composite restorations. Materials and Methods: Sixty freshly extracted, sound molar teeth were selected for the study. A dovetail cavity on the mesio-occlusal and a slot cavity on disto-occlusal surfaces of each tooth were prepared, and the teeth were divided 4 groups which one of them as a control group. The pulp capping materials (TheraCal LC, Calcimol LC, Dycal) applied on pulpo-axial wall of each cavity, and the restoration was completed with composite resin. The teeth were subjected to a compressive load in a universal mechanical testing machine. The surfaces of the tooth and restoration were examined under a stereomicroscope. The data were analyzed using factorial analysis of variance and Tukey's test. Results: For pulp capping materials, the highest fracture load (931.15 ± 203.81 N) and the lowest fracture load (832.28 ± 245.75 N) were calculated for Control and Dycal group, respectively. However, there were no statistically significant differences among all groups (P > 0.05). The fracture load of the dovetail groups was significantly higher than those of the slot cavity groups (P < 0.05). Conclusion: Dovetail cavity design shows better fracture resistance in Class II composite restorations, independent of used or not used pulp capping materials. PMID:26038653

Elementary Teachers' Selection and Use of Visual Models

As science grows in complexity, science teachers face an increasing challenge of helping students interpret models that represent complex science systems. Little is known about how teachers select and use models when planning lessons. This mixed methods study investigated the pedagogical approaches and visual models used by elementary in-service and preservice teachers in the development of a science lesson about a complex system (e.g., water cycle). Sixty-seven elementary in-service and 69 elementary preservice teachers completed a card sort task designed to document the types of visual models (e.g., images) that teachers choose when planning science instruction. Quantitative and qualitative analyses were conducted to analyze the card sort task. Semistructured interviews were conducted with a subsample of teachers to elicit the rationale for image selection. Results from this study showed that both experienced in-service teachers and novice preservice teachers tended to select similar models and use similar rationales for images to be used in lessons. Teachers tended to select models that were aesthetically pleasing and simple in design and illustrated specific elements of the water cycle. The results also showed that teachers were not likely to select images that represented the less obvious dimensions of the water cycle. Furthermore, teachers selected visual models more as a pedagogical tool to illustrate specific elements of the water cycle and less often as a tool to promote student learning related to complex systems.

Domestic violence is the third sociopathology after addiction and child abuse in Iran. Fifty-six percent of Iranian women in the range of 17-32 years old are exposed to the highest domestic violence. Objective: The aim of this study was to design and psychoanalyze a comprehensive questionnaire on coping with domestic violence against women in Iranian society. This study was carried out on a random sample of women exposed to domestic violence and referred to the health and care center of Shahid Beheshti University of Medical Sciences in Tehran, and Forensic Medical Centers in Urmia city (Iran), in 2017. Two hundred questionnaires were distributed among the participants. One hundred sixty-eight questionnaires were returned to the researchers for data analysis. Eight of those were excluded from the analysis because of incompleteness. Finally, exploratory factor analysis was performed. After reviewing the literature, a questionnaire with 32 items was developed. Content validity ratio (0.95) and content validity index (0.97) were obtained. The results of exploratory factor analysis indicated that the questionnaire explained 69.34% of the data variance. Cronbach's alpha coefficient, and test-retest methods were used for determining the reliability and the obtained value, which were 0.82 and 0.81, respectively. Validity and reliability of the questionnaire with 32 items were confirmed. The tool can be utilized to measure how women cope with domestic violence.

Novel N-substituted aminobenzamide scaffold derivatives targeting the dipeptidyl peptidase-IV enzyme.

The dipeptidyl peptidase-IV (DPP-IV) enzyme is considered a pivotal target for controlling normal blood sugar levels in the body. Incretins secreted in response to ingestion of meals enhance insulin release to the blood, and DPP-IV inactivates these incretins within a short period and stops their action. Inhibition of this enzyme escalates the action of incretins and induces more insulin to achieve better glucose control in diabetic patients. Thus, inhibition of this enzyme will lead to better control of blood sugar levels. In this study, computer-aided drug design was used to help establish a novel N-substituted aminobenzamide scaffold as a potential inhibitor of DPP-IV. CDOCKER software available from Discovery Studio 3.5 was used to evaluate a series of designed compounds and assess their mode of binding to the active site of the DPP-IV enzyme. The designed compounds were synthesized and tested against a DPP-IV enzyme kit provided by Enzo Life Sciences. The synthesized compounds were characterized using proton and carbon nuclear magnetic resonance, mass spectrometry, infrared spectroscopy, and determination of melting point. Sixty-nine novel compounds having an N-aminobenzamide scaffold were prepared, with full characterization. Ten of these compounds showed more in vitro activity against DPP-IV than the reference compounds, with the most active compounds scoring 38% activity at 100 μM concentration. The N-aminobenzamide scaffold was shown in this study to be a valid scaffold for inhibiting the DPP-IV enzyme. Continuing work could unravel more active compounds possessing the same scaffold.

What variables can influence clinical reasoning?

Ashoorion, Vahid; Liaghatdar, Mohammad Javad; Adibi, Peyman

2012-01-01

Background: Clinical reasoning is one of the most important competencies that a physician should achieve. Many medical schools and licensing bodies try to predict it based on some general measures such as critical thinking, personality, and emotional intelligence. This study aimed at providing a model to design the relationship between the constructs. Materials and Methods: Sixty-nine medical students participated in this study. A battery test devised that consist four parts: Clinical reasoning measures, personality NEO inventory, Bar-On EQ inventory, and California critical thinking questionnaire. All participants completed the tests. Correlation and multiple regression analysis consumed for data analysis. Results: There is low to moderate correlations between clinical reasoning and other variables. Emotional intelligence is the only variable that contributes clinical reasoning construct (r=0.17-0.34) (R2 chnage = 0.46, P Value = 0.000). Conclusion: Although, clinical reasoning can be considered as a kind of thinking, no significant correlation detected between it and other constructs. Emotional intelligence (and its subscales) is the only variable that can be used for clinical reasoning prediction. PMID:23853636

Self-Efficacy and Functional Status in Schizophrenia: Relationship to Insight, Cognition and Negative Symptoms

PubMed Central

Kurtz, Matthew M.; Olfson, Rachel; Rose, Jennifer

2016-01-01

Self-efficacy, defined as the confidence one has in the ability to perform a behavior or specific task, has been introduced as a crucial motivational factor for successfully carrying out social and everyday living skills (Bandura, 1977, 1997). Few studies have assessed its role in functioning in schizophrenia. The current study was designed to investigate whether degree of illness insight determined whether self-efficacy was a mediator of the relationship between two key illness features, negative symptoms and cognition, and functional skills. Sixty-nine individuals with schizophrenia were administered measures of self-efficacy, cognition, symptoms, insight and performance-based measure of everyday living and social skill. Results revealed that self-efficacy was only linked to measures of functional skills when illness insight was intact. There was evidence of moderation of confounding effects such that when self-efficacy was controlled, the relationship between negative symptoms and measures of everyday life skills became non-significant, but only when illness insight was intact. These findings emphasize the importance of including illness insight in models of the role of self-efficacy in functioning in schizophrenia. PMID:23375941

An educational strategy for using physician assistant students to provide health promotion education to community adolescents.

PubMed

Ruff, Cathy C

2012-01-01

The "Competencies for the Physician Assistant Profession" identify core competencies that physician assistants (PAs) are expected to acquire and maintain throughout their career (see http://www.nccpa.net/pdfs/Definition%20of%20PA%20Competencies% 203.5%20for%20Publication.pdf). Two categories of competencies relate to patient care and interpersonal and communication skills and articulate the need for PAs to be effective communicators and patient educators. The value of a health education curriculum for the adolescent population has been recognized since the early 1900s. PA student-designed health promotion presentations aimed at the adolescent population are an innovative educational strategy involving students in community education. PA student-designed presentations based upon previously identified topics were presented in the community. Students presented topics including Smoking Cessation, The Effects of Drugs and Alcohol, Self-Esteem, and others to adolescents. Community audiences were varied and included alternative high schools and teens within the Department of Youth Corrections facilities. PA students created 17 portable presentations for community adolescents. Two hundred sixty-eight students gave presentations to more than 700 adolescents ranging from 11-22 years of age between the years 2005-2010. Eighty-two percent (646/791) of adolescent participants either strongly agreed or agreed that they learned at least one new piece of information from the presentations. Sixty percent (12/20) of community leaders requested that the PA students return to give additional health promotion presentations. Analysis of comments by PA students revealed that 98% of students found the experience beneficial. Students identified the experience as helping them better understand how to design presentations to meet the needs of their audience, feel more comfortable with adolescents, and gain confidence in communicating. Seventy-five percent stated they would continue to be involved in community education because of the experience. These presentations serve to enrich student professional development, enhance community awareness of the PA profession, and provide educational information to adolescent populations, many of whom are considered at-risk. In addition, this model serves to enhance the service-learning curriculum.

CHAracteristics of research studies that iNfluence practice: a GEneral survey of Canadian orthopaedic Surgeons (CHANGES): a pilot survey.

2015-01-01

Evidence Based Medicine (EBM) is increasingly being applied to inform clinical decision-making in orthopaedic surgery. Despite the promotion of EBM in Orthopaedic Surgery, the adoption of results from high quality clinical research seems highly unpredictable and does not appear to be driven strictly by randomized trial data. The objective of this study was to pilot a survey to determine if we could identify surgeon opinions on the characteristics of research studies that are perceived as being most likely to influence clinical decision-making among orthopaedic surgeons in Canada. A 28-question electronic survey was distributed to active members of the Canadian Orthopaedic Association (COA) over a period of 11 weeks. The questionnaire sought to analyze the influence of both extrinsic and intrinsic characteristics of research studies and their potential to influence practice patterns. Extrinsic factors included the perceived journal quality and investigator profiles, economic impact, peer/patient/industry influence and individual surgeon residency/fellowship training experiences. Intrinsic factors included study design, sample size, and outcomes reported. Descriptive statistics are provided. Of the 109 members of the COA who opened the survey, 95 (87%) completed the survey in its entirety. The overall response rate was 11% (95/841). Surgeons achieved consensus on the influence of three key designs on their practices: 1) randomized controlled trials 94 (99%), 2) meta-analysis 83 (87%), and 3) systematic reviews 81 (85%). Sixty-seven percent of surgeons agreed that studies with sample sizes of 101-500 or more were more likely to influence clinical practice than smaller studies (n = <100). Factors other than design influencing adoption included 1) reputation of the investigators (99%) and 2) perceived quality of the journal (75%). Although study design and sample size (i.e. minimum of 100 patients) have some influence on clinical decision making, surgeon respondents are equally influenced by investigator reputation and perceived journal quality. At present, continued emphasis on the generation of large, methodologically sound clinical trials remains paramount to translating research findings to clinical practice changes. Specific to this pilot survey, strategies to solicit more widespread responses will be pursued.

Accelerated casting techniques have been used, but may not result in castings with matching marginal accuracy. The study measured the marginal gap and determined the clinical acceptability of single cast copings invested in a phosphate-bonded investment with the use of conventional and accelerated methods. One hundred and twenty cast coping samples were fabricated using conventional and accelerated methods, with three finish lines: Chamfer, shoulder and shoulder with bevel. Sixty copings were prepared with each technique. Each coping was examined with a stereomicroscope at four predetermined sites and measurements of marginal gaps were documented for each. A master chart was prepared for all the data and was analyzed using Statistical Package for the Social Sciences version. Evidence of marginal gap was then evaluated by t-test. Analysis of variance and Post-hoc analysis were used to compare two groups as well as to make comparisons between three subgroups . Measurements recorded showed no statistically significant difference between conventional and accelerated groups. Among the three marginal designs studied, shoulder with bevel showed the best marginal fit with conventional as well as accelerated casting techniques. Accelerated casting technique could be a vital alternative to the time-consuming conventional casting technique. The marginal fit between the two casting techniques showed no statistical difference.

The role of carbohydrates on mood and cognition is fairly well established, however research examining the behavioural effects of the other macronutrients is limited. The current study compared the effects of a 25 g glucose drink to energetically matched protein and fat drinks and an inert placebo. Following a blind, placebo-controlled, randomised crossover design, 18 healthy young adults consumed drinks containing fat, glucose, protein and placebo. Cognitive performance was examined at baseline and again 15- and 60 min post drink. Mood was assessed at baseline and then 10-, 35- and 80 min post drink. Attention and speed were enhanced 15 min following fat or glucose ingestion and working memory was enhanced 15 min following protein ingestion. Sixty minutes post drink memory enhancements were observed after protein and memory impairment was observed following glucose. All drinks increased ratings of alertness. The findings suggest that macronutrients: (i) have different windows of opportunity for effects (ii) target different cognitive domains. Copyright © 2012 Elsevier B.V. All rights reserved.

To describe the biomedical and other causes of maternal death in Syria and to assess their preventability. A reproductive age mortality study (RAMOS) design was used to identify pregnancy related deaths. All deaths among women aged 15-49 reported to the national civil register for 2003 were investigated through home interviews. Verbal autopsies were used to ascertain the cause of death among pregnancy related maternal deaths, and causes and preventability of deaths were assessed by a panel of doctors. A total of 129 maternal deaths were identified and reviewed. Direct medical causes accounted for 88%, and haemorrhage was the main cause of death (65%). Sixty nine deaths (54%) occurred during labour or delivery. Poor clinical skills and lack of clinical competency were behind 54% of maternal deaths. Ninety one percent of maternal deaths were preventable. The causes of maternal death in Syria and their contributing factors reflect serious defects in the quality of maternal care that need to be urgently rectified.

The broader cognitive phenotype of autism in parents: how specific is the tendency for local processing and executive dysfunction?

Bölte, Sven; Poustka, Fritz

2006-06-01

The objective of this study was to investigate the tendency for local processing style ('weak central coherence') and executive dysfunction in parents of subjects with an autism spectrum disorder (ASD) compared with parents of individuals with early onset schizophrenia (EOS) and mental retardation (MR). Sixty-two parents of subjects with ASD, 36 parents of subjects with EOS and 30 parents of subjects with MR were examined. Data on two scales indicative of local visual processing (Embedded Figures Test, Block Design) and on three executive function tests (Wisconsin Card Sorting Test, Tower of Hanoi, Trailmaking Test) were collected for all participants. Parents of subjects with ASD performed significantly faster on the Embedded Figures Test compared with both control samples. No other substantial group differences were observed. The findings indicate that an increased tendency for local processing in terms of visual disembedding could be a relatively specific core feature of the broader cognitive phenotype of autism in parents.

Background. Since 2000, studies, experiments, and clinical observations revealed high prevalence of periodontal diseases among children and adolescents. Therefore, this paper was designed to provide an update for dental practitioners on epidemiology, microbiology, pathology, prevention, diagnosis, and treatment of periodontal diseases in children and adolescents. Methods. This paper reviews the current literature concerning periodontal diseases in pediatric dentistry. It includes MEDLINE database search using key terms: “periodontal diseases in children,” “Periodontal diseasesin adolescents,” “periodontal diseases risk factors,” “microbiology of periodontal diseases,” “classification of periodontal diseases,” “epidemiology of periodontal diseases,” and “treatment of periodontal diseases.” Articles were evaluated by title and/or abstract and relevance to pediatric dentistry. Sixty-five citations were selected by this method and by the references within the chosen articles. A review of the comprehensive textbooks on pediatric dentistry and periodontology was done. Some recommendations were based on the opinions of experienced researchers and clinicians, when data were inconclusive. PMID:25053946

Training in psychiatric settings is stressful for nursing students. The purpose of this study was to examine the correlations between the students' characteristics, their stress degrees, stressors and types of coping strategies they experience during training in psychiatric course. A descriptive, correlational, longitudinal design was used. Sixty-five undergraduate nursing students were recruited randomly from five Jordanian universities. Self-report questionnaires were administered at the second semester of the 2012-2013 academic year. The findings showed that students who utilized avoidance or transference strategies reported high stress degrees. Moreover, the results showed that those students who were in the fourth year, with a low family income, who avoid extracurricular activities, with a low academic grade or who registered in other clinical course(s) reported high stress degrees. These findings present a worthy data for the clinical instructors that facilitate students training in psychiatric settings and promote their psychosocial well-being.

Background and aims The aim of this study was to measure the microhardness values of irradiated computer-aided design/computer-aided manufacturing (CAD/CAM) ceramics surfaces before and after thermal treatment. Materials and Methods Sixty CAD/CAM ceramic discs were prepared and grouped by material, i.e. lithium disilicate ceramic (Emax CAD) and zirconia ceramic (Emax ZirCAD). Laser irradiation at the material surface was performed with a carbon dioxide laser at 5 Watt (W) or 10 W power in continuous mode (CW mode), or with a neodymium:yttrium aluminum perovskite (Nd:YAP) laser at 10 W on graphite and non-graphite surfaces. Vickers hardness was tested at 0.3 kgf for lithium disilicate and 1 kgf for zirconia. Results Emax CAD irradiated with CO2 at 5 W increased microhardness by 6.32 GPa whereas Emax ZirCAD irradiated with Nd:YAP decreased microhardness by 17.46 GPa. Conclusion CO2 laser effectively increases the microhardness of lithium disilicate ceramics (Emax CAD). PMID:28740324

Increasing healthy food options in public venues, including recreational facilities, is a health priority. The purpose of this study was to describe the public recreation food environment in British Columbia, Canada using a sequential explanatory mixed methods design. Facility audits assessed policy, programs, vending, concessions, fundraising, staff meetings and events. Focus groups addressed context and issues related to action. Eighty-eighty percent of facilities had no policy governing food sold or provided for children/youth programs. Sixty-eight percent of vending snacks were chocolate bars and chips while 57% of beverages were sugar sweetened. User group fundraisers held at the recreation facilities also sold 'unhealthy' foods. Forty-two percent of recreation facilities reported providing user-pay programs that educated the public about healthy eating. Contracts, economics, lack of resources and knowledge and motivation of staff and patrons were barriers to change. Recreation food environments were obesogenic but stakeholders were interested in change. Technical support, resources and education are needed.

2015-01-01

Stereotactic ablative radiotherapy (SABR) offers a curative treatment for lung cancer in patients who are marginal surgical candidates. However, unlike traditional surgery the lung cancer remains in place after treatment. Thus, imaging follow-up for evaluation of recurrence is of paramount importance. In this retrospective designed Institutional Review Board-approved study, follow-up contrast-enhanced computed tomography (CT) exams were performed on sixty one patients to evaluate enhancement pattern in the ablation zone at 1, 3, 6, and 12 months after SABR. Eleven patients had recurrence within the ablation zone after SABR. The postcontrast enhancement in the recurrence group showed a washin and washout phenomenon, whereas the radiation-induced lung injury group showed continuous enhancement suggesting an inflammatory process. The textural feature of the ablation zone of enhancement and perfusion as demonstrated in computed tomography nodule enhancement may allow early differentiation of recurrence from radiation-induced lung injury in patients' status after SABR or primary lung cancer.

The aim of this study was to evaluate the effectiveness of a distraction-based coping leaflet in reducing distress in women undergoing genetic risk assessment for breast/ovarian cancer. One hundred sixty-two women participated in a randomized controlled trial, receiving either the intervention or standard information. Data were collected through a postal questionnaire at entry into a genetic risk assessment programme and 1 month later. Analysis of covariance revealed a nonsignificant reduction in distress in all women, and a significant reduction of distress among those with high baseline stress, who received the intervention. No gains were found among the control group. Measures of emotional response while thinking about cancer genetic assessment suggested these benefits were achieved in the absence of any rebound emotional response. The intervention offers a low-cost effective coping intervention, which could be integrated into existing services with minimal disruption and may also be appropriate for other periods of waiting and uncertainty.

2017-11-01

The objective of this research was to quantify the effects of driver age, ramp signage configuration, including number of panels, logo format and sign familiarity, on driver performance and attention allocation when exiting freeways. Sixty drivers participated in a simulator study and analysis of variance models were used to assess response effects of the controlled manipulations. Results revealed elderly drivers to demonstrate worse performance and conservative control strategies as compared to middle-aged and young drivers. Elderly drivers also exhibited lower off-road fixation frequency and shorter off-road glance durations compared to middle-aged and young drivers. In general, drivers adopted a more conservative strategy when exposed to nine-panel signs as compared to six-panel signs and were more accurate in target detection when searching six-panels vs. nine and with familiar vs. unfamiliar logos. These findings provide an applicable guide for agency design of freeway ramp signage accounting for driver demographics. Copyright © 2017 Elsevier Ltd. All rights reserved.

The Development of Cognitive Skills and Gains in Academic School Readiness for Children from Low-Income Families

Welsh, Janet A.; Nix, Robert L.; Blair, Clancy; Bierman, Karen L.; Nelson, Keith E.

2010-01-01

This study examined developmental associations between growth in domain-general cognitive processes (working memory and attention control) and growth in domain-specific skills (emergent literacy and numeracy) across the pre-kindergarten year, and their relative contributions to kindergarten reading and math achievement. One hundred sixty-four Head Start children (44% African American or Latino; 57% female) were followed longitudinally. Path analyses revealed that working memory and attention control predicted growth in emergent literacy and numeracy skills during the pre-kindergarten year, and furthermore, that growth in these domain-general cognitive skills made unique contributions to the prediction of kindergarten math and reading achievement, controlling for growth in domain-specific skills. These findings extend research highlighting the importance of working memory and attention control for academic learning, demonstrating the effects in early childhood, prior to school entry. We discuss the implications of these findings for pre-kindergarten programs, particularly those designed to reduce the school readiness gaps associated with socio-economic disadvantage.

2016-07-01

Occupying new, active design office buildings designed for health promotion and connectivity provides an opportunity to evaluate indoor environment effects on healthy behaviour, sedentariness and workplace perceptions. To determine if moving to a health-promoting building changed workplace physical activity, sedentary behaviour, workplace perceptions and productivity. Participants from four locations at the University of Sydney, Australia, relocated into a new active design building. After consent, participants completed an online questionnaire 2 months before moving and 2 months after. Questions related to health behaviours (physical activity and sitting time), musculoskeletal issues, perceptions of the office environment, productivity and engagement. There were 34 participants (60% aged 25-45, 78% female, 84% employed full-time); 21 participants provided complete data. Results showed that after the move participants spent less work time sitting (83-70%; P < 0.01) and more time standing (9-21%; P < 0.01), while walking time remained unchanged. Participants reported less low back pain (P < 0.01). Sixty per cent of participants in the new workplace were in an open-plan office, compared to 16% before moving. Participants perceived the new work environment as more stimulating, better lit and ventilated, but noisier and providing less storage. No difference was reported in daily physical activity, number of stairs climbed or productivity. Moving to an active design building appeared to have physical health-promoting effects on workers, but workers' perceptions about the new work environment varied. These results will inform future studies in other new buildings. © The Author 2016. Published by Oxford University Press on behalf of the Society of Occupational Medicine. All rights reserved.

2006-03-01

Although the Basic Life Support (BLS) ability of a medical student is a crucial competence, poor BLS training programs have been documented worldwide. Better training designs are needed. This study aims to share detailed descriptions and the test results of two cognitive-constructivist training models for the BLS skills in the first year of medical curriculum. A BLS skills training module was implemented in the first year curriculum in the course of 6 years (1997-2003). The content was derived from the European Resuscitation Council Guidelines. Initially, a competence-based model was used and was upgraded to a cognitive apprenticeship model in 2000. The main performance-content type that was expected at the end of the course was: competent application of BLS procedures on manikins and peers at an OSCE as well as 60% achievement in a test consisting of 25 MCQ items. A retrospective cohort survey design using exam results and a self-completed anonymous student ratings' questionnaire were used in order to test models. Training time for individual students varied from 21 to 29 hours. One thousand seven hundred and sixty students were trained. Fail rates were very low (1.0-2.2%). The students were highly satisfied with the module during the 6 years. In the first year of the medical curriculum, a competence-based or cognitive apprenticeship model using cognitive-constructivist designs of skills training with 9 hours theoretical and 12-20 hours long practical sessions took place in groups of 12-17 students; medical students reached a degree of competence to sufficiently perform BLS skills on the manikins and their peers. The cognitive-constructivist designs for skills training are associated with high student satisfaction. However, the lack of controls limits the extrapolation of this conclusion.

Abstract Purpose: Because of limited accessibility to pulmonary rehabilitation programs, patients with chronic obstructive pulmonary disease (COPD) are infrequently provided with patient education resources. To help educate patients with COPD on how to live a better life with diminished breathing capacity, we developed a novel social media resource center containing COPD respiratory therapy and education videos called "COPDFlix." A heuristic evaluation of COPDFlix was conducted as part of a larger study to determine whether the prototype was successful in adhering to formal Web site usability guidelines for older adults. A purposive sample of three experts, with expertise in Web design and health communications technology, was recruited (a) to identify usability violations and (b) to propose solutions to improve the functionality of the COPDFlix prototype. Each expert evaluated 18 heuristics in four categories of task-based criteria (i.e., interaction and navigation, information architecture, presentation design, and information design). Seventy-six subcriteria across these four categories were assessed. Quantitative ratings and qualitative comments from each expert were compiled into a single master list, noting the violated heuristic and type/location of problem(s). Sixty-one usability violations were identified across the 18 heuristics. Evaluators rated the majority of heuristic subcriteria as either a "minor hindrance" (n=32) or "no problem" (n=132). Moreover, only 2 of the 18 heuristic categories were noted as "major" violations, with mean severity scores of ≥3. Mixed-methods data analysis helped the multidisciplinary research team to categorize and prioritize usability problems and solutions, leading to 26 discrete design modifications within the COPDFlix prototype.

A quasiexperimental pre- and posttest design was used to evaluate hand hygiene (HH) rates on a medical-surgical unit. Data were collected by asking patients if they had seen or heard staff members cleaning their hands. Sixty-five percent of patients reported seeing or hearing staff perform HH preintervention and 93% reported observations postintervention (P < .001). Through incorporating an auditory cue we engaged patients while removing the burden placed on them to question health care worker behavior, and increased both staff and patient awareness of personal HH behavior.

2010-04-01

Computerized physician order entry is a required feature for hospitals seeking to demonstrate meaningful use of electronic medical record systems and qualify for federal financial incentives. A national sample of sixty-two hospitals voluntarily used a simulation tool designed to assess how well safety decision support worked when applied to medication orders in computerized order entry. The simulation detected only 53 percent of the medication orders that would have resulted in fatalities and 10-82 percent of the test orders that would have caused serious adverse drug events. It is important to ascertain whether actual implementations of computerized physician order entry are achieving goals such as improved patient safety.

Sixty-five sampling sites, selected by a statistical design to represent lengths of perennial streams in North Dakota, were chosen to be sampled for fish and aquatic insects (macroinvertebrates) to establish unbiased baseline data. Channel catfish and common carp were the most abundant game and large fish species in the Cultivated Plains and Rangeland Plains, respectively. Blackflies were present in more than 50 percent of stream lengths sampled in the State; mayflies and caddisflies were present in more than 80 percent. Dragonflies were present in a greater percentage of stream lengths in the Rangeland Plains than in the Cultivated Plains.

Fullerenes formation in flames

NASA Technical Reports Server (NTRS)

Howard, Jack B.

1993-01-01

Fullerenes are composed of carbon atoms arranged in approximately spherical or ellipsoidal cages resembling the geodesic domes designed by Buckminster Fuller, after whom the molecules were named. The approximately spherical fullerene, which resembles a soccer ball and contains sixty atoms (C60), is called buckminsterfullerene. The fullerene containing seventy carbon atoms (C70) is approximately ellipsoidal, similar to a rugby ball. Fullerenes were first detected in 1985, in carbon vapor produced by laser evaporation of graphite. The closed shell structure, which has no edge atoms vulnerable to reaction, was proposed to explain the observed high stability of certain carbon clusters relative to that of others at high temperatures and in the presence of an oxidizing gas.

Venezuelan Biomedical journals have been confronting, for several years, a gradual decline both, from the standpoint of their management and in the quality of their editorial content. At its highest level, Venezuela had about sixty different titles. But irregular financial support, as well as the lack of a clear official policy, regarding these scientific activities, were some of the reasons that have contributed to this decline. Several recent Venezuelan and international documents provide an important legal support for the design of new official policies and government responsibilities. There is now a valid opportunity to profit from new tools to evaluate and improve the quality of our scientific and editorial activities.

2017-01-01

The purpose of this systematic review was to identify features and effects of information technology (IT)-based interventions on outcomes related to drug-drug interactions (DDI outcomes). A literature search was conducted in Medline, EMBASE, and the Cochrane Library for published English-language studies. Studies were included if a main outcome was related to DDIs, the intervention involved an IT-based system, and the study design was experimental or observational with controls. Study characteristics, including features and effects of IT-based interventions, were extracted. Nineteen studies comprising five randomized controlled trials (RCT), five non-randomized controlled trials (NRCT) and nine observational studies with controls (OWC) were included. Sixty-four percent of prescriber-directed interventions, and all non-prescriber interventions, were effective. Each of the following characteristics corresponded to groups of studies of which a majority were effective: automatic provision of recommendations within the providers' workflow, intervention at the time of decision-making, integration into other systems, and requiring the reason for not following the recommendations. Only two studies measured clinical outcomes: an RCT that showed no significant improvement and an OWC that showed improvement, but did not statistically assess the effect. Most studies that measured surrogate outcomes (e.g. potential DDIs) and other outcomes (e.g. adherence to alerts) showed improvements. IT-based interventions improve surrogate clinical outcomes and adherence to DDI alerts. However, there is lack of robust evidence about their effectiveness on clinical outcomes. It is recommended that researchers consider the identified features of effective interventions in the design of interventions and evaluate the effectiveness on DDI outcomes, particularly clinical outcomes.

2013-01-01

This study was designed to extend research on the relationship between chiropractic students' learning and study strategies and national board examination performance. Sixty-nine first trimester chiropractic students self-administered the Learning and Study Strategies Inventory (LASSI). Linear trends tests (for continuous variables) and Mantel-Haenszel trend tests (for categorical variables) were utilized to determine if the 10 LASSI subtests and 3 factors predicted low, medium and high levels of National Board of Chiropractic Examiners (NBCE) Part 1 scores. Multiple regression was performed to predict overall mean NBCE examination scores using the 3 LASSI factors as predictor variables. Four LASSI subtests (Anxiety, Concentration, Selecting Main Ideas, Test Strategies) and one factor (Goal Orientation) were significantly associated with NBCE examination levels. One factor (Goal Orientation) was a significant predictor of overall mean NBCE examination performance. Learning and study strategies are predictive of NBCE Part 1 examination performance in chiropractic students. The current study found LASSI subtests Anxiety, Concentration, Selecting Main Ideas, and Test Strategies, and the Goal-Orientation factor to be significant predictors of NBCE scores. The LASSI may be useful to educators in preparing students for academic success. Further research is warranted to explore the effects of learning and study strategies training on GPA and NBCE performance.

The impact of occupational health and safety regulations on prevention through design in construction projects: Perspectives from Spain and the United Kingdom.

Martínez-Aires, María Dolores; Rubio Gámez, María Carmen; Gibb, Alistair

2015-01-01

Since the mid-1990 s, Prevention through Design (PtD) has become increasingly prevalent in the built environment. The acceptance of PtD has largely been due to the removal or reduction of risks during the execution phase of construction projects. European States have had the added impetus of national legislation. This paper analyzes the influence of European Union Directive 92/57/EEC on occupational safety and health injury prevention in the project design phase. Qualitative methods comprised individual semi-structured interviews and focus groups with a panel of experts. Sixty individuals from construction and related professions (architects, engineers, constructors, developers, and other construction experts) answered 17 key questions to establish national perceptions of the effectiveness of Directive 92/57/EEC in Spain and the United Kingdom (UK). The implementation of PtD in the project design phase in the UK is clearer since the regulations explicitly state the obligations of project designers as well as those of the coordinator. Interviews with Spanish experts show that, in Spain, the prevention culture is less frequently realized. The most significant differences between the European Directive and national regulations which influence PtD are linked to the Health and Safety Coordinator, and Health and Safety documents.

Further Development of a Robotic-Assisted Transfer Device

Burkman, Jessica; Grindle, Garrett; Wang, Hongwu; Kelleher, Annmarie

2017-01-01

Background: The task of performing transfers, such as from a wheelchair to a bed, has a high risk of injury to both the caregiver and the person being transferred. Although mechanical transfer devices can reduce these risks, these devices are not meant for use in the community and they still place strain on the caregiver when used. Purpose: The aim of this study is to describe feedback gathered from focus groups of potential users of the Robotic-Assisted Transfer Device (RATD) and describe design changes aimed at preparing the device for the next step in the development process. Method: The RATD was transferred to a newer electric-powered wheelchair (EPW), key components were redesigned, and the control program was updated to increase the safety of the device. Two focus groups, one consisting of people with disabilities and the other consisting of clinicians and caregivers, were conducted to gather feedback from potential users. Results: Error checking, safety zones, a motor brake, and a new track helped increase the safety of the device. Sixty-three percent of the people with disabilities and 83% of caregivers surveyed said they would use the device. Conclusions: The results from the focus groups were positive and the design changes were successful, but more development is needed before the RATD can be marketed. PMID:29339890

Cooperative learning as applied to resident instruction in radiology reporting.

PubMed

Mueller, Donald; Georges, Alexandra; Vaslow, Dale

2007-12-01

The study is designed to evaluate the effectiveness of an active form of resident instruction, cooperative learning, and the residents' response to that form of instruction. The residents dictated three sets of reports both before and after instruction in radiology reporting using the cooperative learning method. The reports were evaluated for word count, Flesch-Kincaid grade level, advancement on clinical spectrum, clarity, and comparison to prior reports. The reports were evaluated for changes in performance characteristics between the pre- and postinstruction dictations. The residents' response to this form of instruction was evaluated by means of a questionnaire. The instruction was effective in changing the resident dictations. The results became shorter (P<.035), more complex (P<.0126), and demonstrated increased advancement on clinical spectrum (P<.0204). The resident response to this form of instruction was positive. One hundred percent or respondents indicated enjoyment working with their groups. Seventy-five percent stated they would like to participate in more cooperative learning activities. The least positive responses related to the amount of time devoted to the project. Sixty-three percent of respondents stated that the time devoted to the project was appropriate. Cooperative learning can be an effective tool in the setting of the radiology residency. Instructional time requirements must be strongly considered in designing a cooperative learning program.

Exploring User Experience of a Telehealth System for the Danish TeleCare North Trial.

The aim was to explore user experiences of using a telehealth system (Telekit) designed for the Danish TeleCare North trial. Telekit is designed for patients diagnosed with chronic obstructive pulmonary disease (COPD) in order to manage the disease and support patient empowerment. This article sums up COPD-participants' user experiences in terms of increased sense of freedom, of security, of control, and greater awareness of COPD symptoms. A consecutive sample of sixty participants (27 women, 33 men) were recruited from the TeleCare North trial. At home the participants completed a non-standardised questionnaire while a researcher was present. The questionnaire identified their health status, their use of specific technologies, and their user experiences with the telehealth system. Results from the questionnaire indicate that the majority of participants (88%) considered the Telekit system as easy to use. 43 (72%) participants felt increased sense of security, and 37 (62%) participants felt increased sense of control by using the system. 30 (50%) participants felt greater awareness of their COPD symptoms, but only 16 (27%) participants felt increased freedom. The study has provided a general picture of COPD participants' user experiences which is important to emphasise as it has a bearing on whether a given implementation will be successful or not.

Autonomous Control Capabilities for Space Reactor Power Systems

NASA Astrophysics Data System (ADS)

Wood, Richard T.; Neal, John S.; Brittain, C. Ray; Mullens, James A.

2004-02-01

The National Aeronautics and Space Administration's (NASA's) Project Prometheus, the Nuclear Systems Program, is investigating a possible Jupiter Icy Moons Orbiter (JIMO) mission, which would conduct in-depth studies of three of the moons of Jupiter by using a space reactor power system (SRPS) to provide energy for propulsion and spacecraft power for more than a decade. Terrestrial nuclear power plants rely upon varying degrees of direct human control and interaction for operations and maintenance over a forty to sixty year lifetime. In contrast, an SRPS is intended to provide continuous, remote, unattended operation for up to fifteen years with no maintenance. Uncertainties, rare events, degradation, and communications delays with Earth are challenges that SRPS control must accommodate. Autonomous control is needed to address these challenges and optimize the reactor control design. In this paper, we describe an autonomous control concept for generic SRPS designs. The formulation of an autonomous control concept, which includes identification of high-level functional requirements and generation of a research and development plan for enabling technologies, is among the technical activities that are being conducted under the U.S. Department of Energy's Space Reactor Technology Program in support of the NASA's Project Prometheus. The findings from this program are intended to contribute to the successful realization of the JIMO mission.

Noben, Cindy; Evers, Silvia; Genabeek, Joost van; Nijhuis, Frans; de Rijk, Angelique

2017-04-01

Purpose The purpose of this study is to improve web-based employability interventions for employees with work-related health problems for both intervention content and study design by means of a pilot economic evaluation. Methods Uptake rate analysis for the intervention elements, cost effectiveness, cost utility and subgroup analyses were conducted to identify potential content-related intervention improvements. Differences in work ability and quality-adjusted life years and overall contribution of resource items to the total costs were assessed. These were used to guide study design improvements. Results Sixty-three participants were a-select allocated to either the intervention (n = 29) or the control (n = 34) group. Uptake regarding the intervention elements ranged between 3% and 70%. Cost-effectiveness and cost-utility analyses resulted in negative effects although higher total costs. Incremental effects were marginal (work ability -0.51; QALY -0.01). Conclusions The web-based tool to enhance employability among work disabled employees requires improvements regarding targeting and intensity; outcome measures selected and collection of cost data. With respect to the studies of disability and rehabilitation, the findings and methods presented in this pilot economic evaluation could guide the assessment of future assistive "e-health" technologies. IMPLICATIONS FOR REHABILITATION The methods presented in this pilot economic evaluation have large potentials to guide the assessment of future assistive e-health technologies addressing work-disabilities. The findings show that the web-based tool requires content related improvements with respect to targeting and intensity to enhance employability among work disabled employees. The findings show that the web-based tool would benefit from improvements related to the study design by more adequately selecting and collecting both outcome measures and cost data. The burden attributable to large-scale studies and implementation issues were prevented as the outcomes of the pilot economic evaluation did not support the implementation of the web-based tool.

Evaluation of statistical designs in phase I expansion cohorts: the Dana-Farber/Harvard Cancer Center experience.

PubMed

Dahlberg, Suzanne E; Shapiro, Geoffrey I; Clark, Jeffrey W; Johnson, Bruce E

2014-07-01

Phase I trials have traditionally been designed to assess toxicity and establish phase II doses with dose-finding studies and expansion cohorts but are frequently exceeding the traditional sample size to further assess endpoints in specific patient subsets. The scientific objectives of phase I expansion cohorts and their evolving role in the current era of targeted therapies have yet to be systematically examined. Adult therapeutic phase I trials opened within Dana-Farber/Harvard Cancer Center (DF/HCC) from 1988 to 2012 were identified for sample size details. Statistical designs and study objectives of those submitted in 2011 were reviewed for expansion cohort details. Five hundred twenty-two adult therapeutic phase I trials were identified during the 25 years. The average sample size of a phase I study has increased from 33.8 patients to 73.1 patients over that time. The proportion of trials with planned enrollment of 50 or fewer patients dropped from 93.0% during the time period 1988 to 1992 to 46.0% between 2008 and 2012; at the same time, the proportion of trials enrolling 51 to 100 patients and more than 100 patients increased from 5.3% and 1.8%, respectively, to 40.5% and 13.5% (χ(2) test, two-sided P < .001). Sixteen of the 60 trials (26.7%) in 2011 enrolled patients to three or more sub-cohorts in the expansion phase. Sixty percent of studies provided no statistical justification of the sample size, although 91.7% of trials stated response as an objective. Our data suggest that phase I studies have dramatically changed in size and scientific scope within the last decade. Additional studies addressing the implications of this trend on research processes, ethical concerns, and resource burden are needed. © The Author 2014. Published by Oxford University Press.

2017-06-01

This study aimed to evaluate changes in evidence-based practice (EBP) knowledge, attitudes, and practice of nursing students before and after completing an online, graduate level, introductory research/EBP course. A prospective one-group pretest-posttest design. A private university in the Midwestern, USA. Sixty-three online nurse practitioner students in Master's program. A convenient sample of online graduate nursing students who enrolled in the research/EBP course was invited to participate in the study. Study outcomes were measured using the Evidence-Based Practice Questionnaire (EBPQ) before and after completing the course. Descriptive statistics and paired-Samples t-test was used to assess the mean differences between pre-and post-test scores. Overall, students' post-test EBP scores were significantly improved over pre-test scores, t(63)=-9.034, p<0.001). Statistically significant differences were found for practice of EBP mean scores t(63)=-12.78, p=0.001). No significant differences were found between pre and post-tests on knowledge and attitudes toward EBP scores. Most frequently cited barriers to EBP were lack of understanding of statistics, interpretation of findings, lack of time, and lack of library resources. Copyright © 2017 Elsevier Ltd.

Effects of an intervention to promote socioemotional development in terms of attachment security: a study in early institutionalization in Chile.

PubMed

Lecannelier, Felipe; Silva, Jaime R; Hoffmann, Marianela; Melo, Rolando; Morales, Raquel

2014-01-01

The Chilean government commissioned a quasi-experimental study with a pre-/postintervention design that had two general aims: (a) to assess infants' psychoaffective developmental levels (pre-intervention phase) and (b) to evaluate whether an intervention based on the promotion of socioemotional development modifies the infant's psychoaffective development. Sixty-two institutionalized infants and their alternative caregivers were evaluated at a pre-intervention stage. An intervention then took place, with the caregivers trained according to an "attachment sensitivity manual." Results showed normal ranges of psychomotor development (64% normal, 9% delayed) and a very high frequency of attachment insecurity, as compared to the normative population (53%).The intervention significantly improved social orientation and object orientation as well as activity and reactivity levels. We conclude that although institutionalized infants in Chile do not exhibit high levels of atypical attachment, socioemotional deterioration may lead to vulnerability in present and future development. Finally, the scope of this study affected public policies regarding children, initiating a change to a foster family system and a variety of modifications in the strategies for adopting institutionalized infants. © 2014 Michigan Association for Infant Mental Health.

Yoon, Hee Sang; Kim, Gyung Hee; Kim, Jiyoung

2011-12-01

The purpose of this study was to examine the effectiveness of an interpersonal relationship program on interpersonal relationships, self-esteem, and depression in nursing students. This was a quasi-experiment with a nonequivalent control group pre-posttest design. Sixty-four nursing students participated in the study with 31 in the experimental group and 33 in the control group. They were from 3 different colleges of nursing located in Seoul. The interpersonal relationship program was held 10 times over 10 weeks, taking 90 minutes per session. The interpersonal relationship change scale developed by Schlein and Guemey, Rosenberg's self-esteem scale, and CED-S for depression were the instruments used in the study.

Licorice is an important traditional Chinese medicine with clinical and industrial applications. Genetic resources of licorice are insufficient for analysis of molecular biology and genetic functions; as such, transcriptome sequencing must be conducted for functional characterization and development of molecular markers. In this study, transcriptome sequencing on the Illumina HiSeq 2500 sequencing platform generated a total of 5.41 Gb clean data. De novo assembly yielded a total of 46,641 unigenes. Comparison analysis using BLAST showed that the annotations of 29,614 unigenes were conserved. Further study revealed 773 genes related to biosynthesis of secondary metabolites of licorice, 40 genes involved in biosynthesis of the terpenoid backbone, and 16 genes associated with biosynthesis of glycyrrhizic acid. Analysis of unigenes larger than 1 Kb with a length of 11,702 nt presented 7,032 simple sequence repeats (SSR). Sixty-four of 69 randomly designed and synthesized SSR pairs were successfully amplified, 33 pairs of primers were polymorphism in in Glycyrrhiza uralensis Fisch., Glycyrrhiza inflata Bat., Glycyrrhiza glabra L. and Glycyrrhiza pallidiflora Maxim. This study not only presents the molecular biology data of licorice but also provides a basis for genetic diversity research and molecular marker-assisted breeding of licorice. PMID:26571372

The objective of this study was to determine the impact on emergency department (ED) operations of Hurricane Hugo, a class IV hurricane that struck Charleston, South Carolina, on September 21, 1989. The study design was a retrospective record-based descriptive study and mail survey of the ED of a 300-bed regional medical center directly in the path of the storm. During the 3 weeks after the storm, ED patient volume increased 19% over that of the 3 weeks before the storm. Increased visit volumes were evident for at least 3 months. Compared with a similar period of the previous year, there was an increase in the proportion of patients seen for lacerations of all types, puncture wounds, stings, and falls. Sixty-two percent of physician offices were still closed 7 days after the storm. The direct effects of a class IV hurricane on ED operations included major alterations in the volume and types of patient visits. Because of the evacuation of approximately 40% of the coastal population and storm damage hindering travel, the increase in visit volume was less in magnitude but of longer duration has been reported in class III hurricanes.

PubMed

Bosquet, Antoine; El Massioui, Farid; Mahé, Isabelle

2015-01-01

To assess voting conditions in long-term care settings, we conducted a multicenter survey after the 2009 European elections in France. A questionnaire about voting procedures and European elections was proposed in 146 out of 884 randomized facilities. Sixty-four percent of facilities answered the questionnaire. Four percent of residents voted (national turnout: 40%), by proxy (58%) or at polling places (42%). Abstention related to procedural issues was reported in 32% of facilities. Sixty-seven percent of establishments had voting procedures, and 53% declared that they assessed residents' capacity to vote. Assistance was proposed to residents for voter registration, for proxy voting, and for voting at polling places, respectively, in 33%, 87%, and 80% of facilities. This survey suggests that residents may be disenfranchised and that more progress should be made to protect the voting rights of residents in long-term care facilities.

2010-09-01

Cardiovascular system abnormalities are common causes of morbidity and mortality in sickle cell anaemia. The study aims at determining the pattern of electrocardiographic changes in adult Nigerian sickle cell anaemia patients. A descriptive cross sectional study was done on sixty sickle cell anaemia patients seen at the adult sickle cell clinic of University of Nigeria Teaching Hospital (UNTH) Enugu, and sixty age and sex matched normal controls. All the subjects had clinical evaluation as well as electrocardiographic examination. The mean heart rate, P-wave duration, P-wave dispersion, PR interval, QRS duration, QRS dispersion, QTc interval and QTc dispersion were significantly higher in the patients than in the control group. Electrocardiographic abnormalities identified by this study were: left ventricular hypertrophy (75%; 1.7%), left atrial enlargement (40%; 0%), biventricular hypertrophy (11%; 0), ST-segment elevation (10%; 0%) and increased P-wave and QTc dispersions. ST segment elevation was found more in patients with moderate and severe anaemia (P= 0.02, Spearman correlation r= 0.342; P= 0.007), Sickle cell anaemia is associated with significant electrocardiographic abnormalities. Further prospective studies are recommended to evaluate the prognostic significance of the electrocardiographic intervals dispersion on the long term disease outcome in sickle cell anaemia.

Schneider, Carl Richard; Naughtin, Clare Louise; Wilson, Frances; de Almeida Neto, Abilio Cesar; Moles, Rebekah Jane

2017-01-01

Objectives To determine whether repeated mystery shopping visits with feedback improve pharmacy performance over nine visits and to determine what factors predict an appropriate outcome. Design Prospective, parallel, repeated intervention, repeated measures mystery shopping (pseudopatient) design. Setting Thirty-six community pharmacies in metropolitan Sydney, Australia in March–October 2015. Participants Sixty-one University of Sydney pharmacy undergraduates acted as mystery shoppers. Students enrolled in their third year of Bachelor of Pharmacy in 2015 were eligible to participate. Any community pharmacy in the Sydney metropolitan region was eligible to take part and was selected through convenience sampling. Intervention Repeated mystery shopping with immediate feedback and coaching. Outcome measures Outcome for each given scenario (appropriate or not) and questioning scores for each interaction. Results Five hundred and twenty-one visits were analysed, of which 54% resulted in an appropriate outcome. Questioning scores and the proportion of interactions resulting in an appropriate outcome significantly improved over time (P<0.001). Involvement of pharmacists, visit number, increased questioning score and the prescribed scenario were predictors of an appropriate outcome (P=0.008, P=0.022, P<0.001 and P<0.001, respectively). Interactions involving a pharmacist had greater scores than those without (P<0.001). Conclusions Repeated mystery shopping visits with feedback were associated with improved pharmacy performance over time. Future work should focus on the role of non-pharmacist staff and design interventions accordingly. PMID:29247115

Five stroke survivors suffered hemiplegia (2,5%), 24 (12%) experienced moderate consequences and 143 (71,5%) had mild consequences. No neurological deficit had 28 (14%) stroke survivors. Six months after the onset of disease all stroke survivors have been followed-up and evaluated about quality of life by filling in a modified questionnaire: Questionnaire on Quality of Life after Stroke (2). The questionnaire contained 20 questions covering four fields of life: Working Ability, Home Activity, Family Relations and Leisure Activities. Six months after the onset of stroke a worse quality of life in comparison to the period before the disease was noted in 172 (86%) stroke survivors, the unchanged in 19 (9,5%) and better in 9 (4,5%). The most affected is the field "Leisure Activities", followed by "Family Relations", "Home Activity", and the least affected is "Work Ability". The neurological deficit significantly correlates to the "Home Activities" and "Leisure Activities".
