A randomised controlled trial to assess the effectiveness of offering study results as an incentive to increase response rates to postal questionnaires [ISRCTN26118436  

PubMed Central

Background Postal questionnaires are widely used to collect outcome data on participants. However, a poor response to questionnaires will reduce the statistical power of the study and may introduce bias. A meta analysis of ten trials offering study results, largely in the fields of education and marketing, was shown to be ineffective, with the odds ratio for response with offering research findings is 0.92 (95% CI 0.75 to 1.11). However uncertainty still exists as it is uncertain whether results from such trials can be extrapolated to that of a health care setting. The aim of this study was to assess whether offering participants study results increases the response rates to postal questionnaires. Methods 1038 women aged over 70 years were remotely randomised by computer in a 3:1 ratio. 250 participants did not receive the offer of knowing the results of the trial and 788 participants were offered the results of the trial in a postal questionnaire. The main outcome measure was response rate. Chi square test was used to evaluate the overall differences in response rate between the two groups. An adjusted analysis, adjusting for whether the participant was taking calcium and age was also undertaken. Results The response rates were not significantly different Odds Ratio 0.88 (95% confidence intervals 0.48 to 1.63) p = 0.69. Conclusion Offering study results to women living in the community aged over 70 does not increase response rates to postal questionnaires. Although researchers have an ethical obligation to offer participants study results, since 10% of women did not wish to receive the results, investigators should give participants the option to opt out of receiving the study's results.

Increasing response rates to postal questionnaires: systematic review  

PubMed Central

Objective To identify methods to increase response to postal questionnaires. Design Systematic review of randomised controlled trials of any method to influence response to postal questionnaires. Studies reviewed 292 randomised controlled trials including 258?315 participants Intervention reviewed 75 strategies for influencing response to postal questionnaires. Main outcome measure The proportion of completed or partially completed questionnaires returned. Results The odds of response were more than doubled when a monetary incentive was used (odds ratio 2.02; 95% confidence interval 1.79 to 2.27) and almost doubled when incentives were not conditional on response (1.71; 1.29 to 2.26). Response was more likely when short questionnaires were used (1.86; 1.55 to 2.24). Personalised questionnaires and letters increased response (1.16; 1.06 to 1.28), as did the use of coloured ink (1.39; 1.16 to 1.67). The odds of response were more than doubled when the questionnaires were sent by recorded delivery (2.21; 1.51 to 3.25) and increased when stamped return envelopes were used (1.26; 1.13 to 1.41) and questionnaires were sent by first class post (1.12; 1.02 to 1.23). Contacting participants before sending questionnaires increased response (1.54; 1.24 to 1.92), as did follow up contact (1.44; 1.22 to 1.70) and providing non-respondents with a second copy of the questionnaire (1.41; 1.02 to 1.94). Questionnaires designed to be of more interest to participants were more likely to be returned (2.44; 1.99 to 3.01), but questionnaires containing questions of a sensitive nature were less likely to be returned (0.92; 0.87 to 0.98). Questionnaires originating from universities were more likely to be returned than were questionnaires from other sources, such as commercial organisations (1.31; 1.11 to 1.54). Conclusions Health researchers using postal questionnaires can improve the quality of their research by using the strategies shown to be effective in this systematic review. What is already known on this topicPostal questionnaires are widely used in the collection of data in epidemiological studies and health researchNon-response to postal questionnaires reduces the effective sample size and can introduce biasWhat this study addsThis systematic review includes more randomised controlled trials than any previously published review or meta-analysis no questionnaire responseThe review has identified effective ways to increase response to postal questionnairesThe review will be updated regularly in the Cochrane Library

German version of the whiplash disability questionnaire: reproducibility and responsiveness  

PubMed Central

Background The Whiplash Disability Questionnaire (WDQ) poses a validated tool for the assessment of patients who experience whiplash-associated disorders. A German translation and cross-cultural adaptation was recently produced and presented high validity and internal consistency. As a follow-up, the presented study tests the translated Whiplash Disability Questionnaire’s (WDQ-G) retest reliability and responsiveness to change. Methods The WDQ-G was assessed on three different measurement events: first upon entry (ME1), second four days after entry (ME2), and third at discharge (ME3). Test-retest reliability data from ME1 and ME2 was analysed in a group of stable patients to obtain the intraclass correlation coefficient (ICC) and the standard error of measurement (SEM). To test the instrument’s responsiveness, WDQ-G change data were compared to concurrent instruments. The probability of each instrument, to correctly distinguish patients of the stable phase (ME1 to ME2) from patients who deemed to have improved between from ME1 to ME3, was analysed. Results In total, 53 patients (35 females, age?=?45?±?12.2) were recruited. WDQ-G scores changed from ME1 to ME2 by 5.41?±?11.6 points in a stable group. This corresponds to a test-retest reliability of ICC?=?0.91 (95% CI?=?0.80–0.95) with a SEM of 6.14 points. Minimal Detectable Change, at 95% confidence, was calculated to be 17 points change in scores. Area under Receiver Operator Characteristics of the WDQ-G’s responsiveness revealed a probability of 84.6% (95% CI?=?76.2%–93%) to correctly distinguish between improved and stable patients. Optimal sensitivity (73.2%) and specificity (76.2%) was established at 11-point change. Conclusions High retest reliability and good responsiveness of the WDQ-G support clinical implementation of the translated version. The data suggest, that change in total score greater than eleven points can be interpreted as clinical relevant from a patient’s perspective. Minimal Important Change is suggested at 15 points where there is still high specificity and a 90% confidence MDC.

Raising future forensic pathologists (first report): results of a preliminary questionnaire survey.  

PubMed

The shortage of future forensic pathologists is a serious problem both in Japan and overseas. In Japan, however, factors such as government budget cuts and increasing the autopsy rates, make the condition even worse. In an attempt to improve this situation, we implemented a questionnaire survey to investigate the particular features necessary when selecting a career in forensic medicine. As a preliminary study, we sent the questionnaire along with an anonymous answer sheet to all forensic pathologists with a degree in medicine M.D., who were affiliated with universities in Hokkaido and the Tohoku district of Japan as of August 2011. Thirteen physicians in nine universities (response rate 77.8%) returned the answer sheet. Characteristics of participants are listed below: years of experience, board specialty and number of years as board certified specialists, percentage of work effort spent on autopsy practice, the time when they decided to work as a forensic pathologist, the time when to best recommend forensic pathologist as a career, and crucial factors in choosing the specialty of forensic medicine. As a result of this research, we've revealed the importance of undergraduate medical education or the effect on the role models. Furthermore, we've also extracted miscellaneous comments, such as standardization of minimum requirements. In our study, we' ve found some clues to increase future candidates in the field forensic medicine. However, we must collect further samples for our questionnaire survey to validate the study, and, as a future project, we must also address this problem at the congress of forensic medicine.

The clinical utility of the Social Responsiveness Scale and Social Communication Questionnaire in tuberous sclerosis complex.  

PubMed

Tuberous sclerosis complex (TSC) is often associated with epilepsy, mental retardation, and autism spectrum disorders (ASDs). Thus, screening for ASDs is important when evaluating these individuals. We examined the utility of the Social Responsiveness Scale (SRS) and Social Communication Questionnaire (SCQ), two measures for screening for ASDs, in a TSC population. Twenty-one children were evaluated, with 52.4% classified as having ASDs on the SRS and 42.9% classified as such on the SCQ. Number of antiepileptic drugs significantly correlated with SRS Total score, as did level of intellectual functioning. Evidence for convergent validity was obtained between the SRS and SCQ Total scores (r=0.605). Moreover, all SRS subscales correlated with SCQ Total score (r>0.400). All SCQ subscales except for Communication correlated with SRS total. Overall, the results demonstrate that these questionnaires appear to be effective screens for ASDs in a TSC population and are measuring similar constructs. PMID:20554253

Effect of questionnaire length, personalisation and reminder type on response rate to a complex postal survey: randomised controlled trial  

PubMed Central

Background Minimising participant non-response in postal surveys helps to maximise the generalisability of the inferences made from the data collected. The aim of this study was to examine the effect of questionnaire length, personalisation and reminder type on postal survey response rate and quality and to compare the cost-effectiveness of the alternative survey strategies. Methods In a pilot study for a population study of travel behaviour, physical activity and the environment, 1000 participants sampled from the UK edited electoral register were randomly allocated using a 2 × 2 factorial design to receive one of four survey packs: a personally addressed long (24 page) questionnaire pack, a personally addressed short (15 page) questionnaire pack, a non-personally addressed long questionnaire pack or a non-personally addressed short questionnaire pack. Those who did not return a questionnaire were stratified by initial randomisation group and further randomised to receive either a full reminder pack or a reminder postcard. The effects of the survey design factors on response were examined using multivariate logistic regression. Results An overall response rate of 17% was achieved. Participants who received the short version of the questionnaire were more likely to respond (OR = 1.48, 95% CI 1.06 to 2.07). In those participants who received a reminder, personalisation of the survey pack and reminder also increased the odds of response (OR = 1.44, 95% CI 1.01 to 1.95). Item non-response was relatively low, but was significantly higher in the long questionnaire than the short (9.8% vs 5.8%; p = .04). The cost per additional usable questionnaire returned of issuing the reminder packs was £23.1 compared with £11.3 for the reminder postcards. Conclusions In contrast to some previous studies of shorter questionnaires, this trial found that shortening a relatively lengthy questionnaire significantly increased the response. Researchers should consider the trade off between the value of additional questions and a larger sample. If low response rates are expected, personalisation may be an important strategy to apply. Sending a full reminder pack to non-respondents appears a worthwhile, albeit more costly, strategy.

Does a monetary incentive improve the response to a postal questionnaire in a randomised controlled trial? The MINT incentive study  

PubMed Central

Background Sending a monetary incentive with postal questionnaires has been found to improve the proportion of responders, in research in non-healthcare settings. However, there is little research on use of incentives to improve follow-up rates in clinical trials, and existing studies are inconclusive. We conducted a randomised trial among participants in the Managing Injuries of the Neck Trial (MINT) to investigate the effects on the proportion of questionnaires returned and overall non-response of sending a £5 gift voucher with a follow-up questionnaire. Methods Participants in MINT were randomised to receive either: (a) a £5 gift voucher (incentive group) or (b) no gift voucher (no incentive group), with their 4 month or 8 month follow-up questionnaire. We recorded, for each group, the number of questionnaires returned, the number returned without any chasing from the study office, the overall number of non-responders (after all chasing efforts by the study office), and the costs of following up each group. Results 2144 participants were randomised, 1070 to the incentive group and 1074 to the no incentive group. The proportion of questionnaires returned (RR 1.10 (95% CI 1.05, 1.16)) and the proportion returned without chasing (RR 1.14 (95% CI 1.05, 1.24) were higher in the incentive group, and the overall non-response rate was lower (RR 0.68 (95% CI 0.53, 0.87)). Adjustment for injury severity and hospital of recruitment to MINT made no difference to these results, and there were no differences in results between the 4-month and 8-month follow up questionnaires. Analysis of costs suggested a cost of £67.29 per additional questionnaire returned. Conclusion Monetary incentives may be an effective way to increase the proportion of postal questionnaires returned and minimise loss to follow-up in clinical trials.

Personally addressed hand-signed letters increase questionnaire response: a meta-analysis of randomised controlled trials  

PubMed Central

Background Postal questionnaires are commonly used to collect data for health studies, but non-response reduces study sample sizes and can introduce bias. Finding ways to increase the proportion of questionnaires returned would improve research quality. We sought to quantify the effect on response when researchers address participants personally by name on letters that accompany questionnaires. Methods All randomised controlled trials in a published systematic review that evaluated the effect on response of including participants' names on letters that accompany questionnaires were included. Odds ratios for response were pooled in a random effects meta-analysis and evidence for changes in effects over time was assessed using random effects meta-regression. Results Fourteen randomised controlled trials were included covering a wide range of topics. Most topics were unrelated to health or social care. The odds of response when including participants' names on letters were increased by one-fifth (pooled OR 1.18, 95% CI 1.03 to 1.34; p = 0.015). When participants' names and hand-written signatures were used in combination, the effect was a more substantial increase in response (OR 1.45, 95% CI 1.27 to 1.66; p < 0.001), corresponding to an absolute increase in the proportion of questionnaires returned of between 4% and 10%, depending on the baseline response rate. There was no evidence that the magnitude of these effects had declined over time. Conclusion This meta-analysis of the best available evidence indicates that researchers using postal questionnaires can increase response by addressing participants by name on cover letters. The effect appears to be enhanced by including hand-written signatures.

Coping and involuntary responses to stress in Chinese university students: psychometric properties of the responses to stress questionnaire.  

PubMed

Our objective in this study was to develop a Chinese version of the Responses to Stress Questionnaire (RSQ; Connor-Smith, Compas, Wadsworth, Thomsen, and Saltzman, 2000) and to evaluate its reliability and validity. The Chinese (C) RSQ (RSQ-C) exhibited moderate internal consistency and moderate test-retest reliability. Results of the confirmatory factor analyses indicated that the fit of a 3-factor model of voluntary coping and a separate 2-factor model of involuntary responses to stress were acceptable for the Chinese university sample. With regard to predictive validity, the Primary and Secondary Control Engagement Coping factors were associated with lower levels of depressive and anxious symptoms, whereas the Disengagement, Involuntary Engagement, and Involuntary Disengagement Coping factors were associated with higher levels of such symptoms.

Factors influencing prescribing behaviour of physicians in Greece and Cyprus: results from a questionnaire based survey  

PubMed Central

Background Over the past few decades, drug and overall healthcare expenditure have risen rapidly in most countries. The present study investigates the attitudes and the factors which influence physician prescribing decisions and practice in Greece and Cyprus. Methods A postal questionnaire was developed by researchers at the Department of Health Economics at the National School of Public Health in Greece, specifically for the purposes of the study. This was then administered to a sample of 1,463 physicians in Greece and 240 physicians in Cyprus, stratified by sex, specialty and geographic region. Results The response rate was 82.3% in Greece and 80.4% in Cyprus. There were similarities but also many differences between the countries. Clinical effectiveness is the most important factor considered in drug prescription choice in both countries. Greek physicians were significantly more likely to take additional criteria under consideration, such as the drug form and recommended daily dose and the individual patient preferences. The list of main sources of information for physicians includes: peer-reviewed medical journals, medical textbooks, proceedings of conferences and pharmaceutical sales representatives. Only half of prescribers considered the cost carried by their patients. The majority of doctors in both countries agreed that the effectiveness, safety and efficacy of generic drugs may not be excellent but it is acceptable. However, only Cypriot physicians actually prescribe them. Physicians believe that new drugs are not always better and their higher prices are not necessarily justified. Finally, doctors get information regarding adverse drug reactions primarily from the National Organisation for Medicines. However, it is notable that the majority of them do not inform the authorities on such reactions. Conclusion The present study highlights the attitudes and the factors influencing physician behaviour in the two countries and may be used for developing policies to improve their choices and hence to increase clinical and economic effectiveness and efficiency.

Depressive and Aggressive Responses to Frustration: Development of a Questionnaire and Its Validation in a Sample of Male Alcoholics  

PubMed Central

Since clinical and biochemical observations point to much overlap between depression and aggression, both characterised by intolerance to frustration, a questionnaire was developed to test if different patterns of depressive and aggressive reactions elicited by exposure to negative events and deprivation from expected positive ones in human and nonhuman conditions, respectively, would result in specific response patterns in depressive and aggressive persons. The questionnaire was tested for internal consistency in a pilot healthy sample and for correlations of responses with the personality factors of Aggression and Depression in 60 abstinent male alcoholics. Aggressive and depressive responses were highly correlated across all stimulus conditions, and not specifically but rather equally associated with the personality factors of Aggression and Depression, confirming the close association between these dimensions.

Background The aim of this study was to compare the responsiveness of the European Organization for Research and Treatment (EORTC) quality of life questionnaires (QLQ-C30, QLQ-CR38) and the Functional Assessment of Cancer Therapy-colorectal version 4 questionnaire (FACT-C). Method This prospective study included 127 patients with colorectal cancer: 71 undergoing chemotherapy and 56 radiation therapy. Responsiveness statistics included the Standardized Response Mean (SRM) and the Effect Size (ES). The patient's overall assessment of his/her change in state of health status was the reference criterion to evaluate the responsiveness of the QoL questionnaires. Results 34 patients perceived their health as stable and 17 as improved between the first and the fourth courses of chemotherapy. 21 patients perceived their health as stable and 22 as improved between before and the last week of radiotherapy. The responsiveness of the 3 questionnaires differed according to treatments. The EORTC QLQ-C30 questionnaire was more responsive in patients receiving chemotherapy, particulary functional scales (SRM > 0.55). The QLQ-CR38 and the FACT-C questionnaires provided little clinically relevant information during chemotherapy or radiotherapy. Conclusion The EORTC QLQ-C30 questionnaire appears to be more responsive in patients receiving chemotherapy.

Activity limitations in patients with neuromuscular disorders: a responsiveness study of the ACTIVLIM questionnaire.  

PubMed

Recently, a self-reported scale of activity limitations, the ACTIVLIM questionnaire, was developed and validated in patients with neuromuscular disorders (NMD). The purpose of this study was to investigate its sensitivity to change. One hundred thirty-two patients with NMD (mean age, range: 31, 6-80) were assessed twice, with 21+/-4 months in between, using the ACTIVLIM questionnaire. Mean score change, effect size, standardized response, mean paired t-test and an individual-level statistical approach were calculated for groups of patients according to their self-rated functional status evolution and for three main diagnostic groups (Ambulant and wheelchair-bound Duchenne muscular dystrophy patients, myotonic dystrophy patients, and patients with Charcot-Marie-Tooth neuropathy). The responsiveness indices showed that the change in activity measures was higher in patients who reported deteriorated functional status and in patients with Duchenne muscular dystrophy. The ACTIVLIM questionnaire showed a good sensitivity to change and could be useful in research settings to characterize the disease course of NMD. PMID:19167889

ObjectivesIn self-completed surveys, anonymous questionnaires are sometimes numbered so as to avoid sending reminders to initial nonrespondents. This number may be perceived as a threat to confidentiality by some respondents, which may reduce the response rate, or cause social desirability bias. In this study, we evaluated whether using nonnumbered vs. numbered questionnaires influenced the response rate and the response content.

Development of a Short Version of the Visual Function Questionnaire Using Item-Response Theory  

PubMed Central

Purpose In clinical ophthalmology as in other fields, measuring patient-reported outcomes imposes a burden on patients. To decrease that burden, we used item-response theory (IRT) to develop and test a short version of the National Eye Institute's Visual Function Questionnaire (VFQ). Methods We analyzed VFQ data from 276 adults in Japan. Most of them had glaucoma, cataract, or macular degeneration. Their visual acuity (Snellen fraction) averaged 20/120 (range: 20/13 to 20/2000) for the better eye, and 20/200 (range: 20/13 to 20/2000) for the worse eye. We used a polytomous IRT model, the Generalized Partial Credit Model as implemented in software for parameter scaling of rating data (PARSCALE). To select items for inclusion in the short version we examined each item's location on the latent-trait continuum, its slope, and its frequency of missing data. We also ensured representation of all 7 domains that are important in Japan. To examine the characteristics of the resulting scale, we computed its test information (an index of precision that can vary with the value of the latent trait), and carried out validation testing. Results From 32 of the original VFQ items, we selected 11. The scale comprising those 11 items (the VFQ-J11) had test information greater than 9 for values of the latent trait between ?2.0 and +0.8. The item thresholds were well-targeted for patients with vision problems. Scores on the VFQ-J11 correlated strongly and in the expected direction with measures of visual field and corrected visual acuity. As expected for a valid measure, those scores also improved by a large amount (almost one standard deviation) after cataract surgery. Conclusion This 11-item instrument can provide reliable and the valid data on visual functioning in patients with ophthalmic problems. It is expected to be less of a burden on respondents, while it maintains good psychometric properties.

Occupational health risks of pathologists - results from a nationwide online questionnaire in Switzerland  

PubMed Central

Background Pathologists are highly trained medical professionals who play an essential part in the diagnosis and therapy planning of malignancies and inflammatory diseases. Their work is associated with potential health hazards including injuries involving infectious human tissue, chemicals which are assumed to be carcinogenic or long periods of microscope and computer work. This study aimed to provide the first comprehensive assessment of the health situation of pathologists in Switzerland. Methods Pathologists in Switzerland were contacted via the Swiss Society of Pathologists and asked to answer an ethically approved, online anonymous questionnaire comprising 48 questions on occupational health problems, workplace characteristics and health behaviour. Results 163 pathologists participated in the study. Forty percent of pathologists reported musculoskeletal problems in the previous month. The overall prevalence was 76%. Almost 90% of pathologists had visual refraction errors, mainly myopia. 83% of pathologists had experienced occupational injuries, mostly cutting injuries, in their professional career; more than one fifth of participants reported cutting injuries in the last year. However, long lasting injuries and infectious diseases were rare. Depression and burnout affected every eighth pathologist. The prevalence of smoking was substantially below that of the general Swiss population. Conclusions The results of this study suggest that more care should be taken in technical and personal protective measures, ergonomic workplace optimisation and reduction of work overload and work inefficiencies. Despite the described health risks, Swiss pathologists were optimistic about their future and their working situation. The high rate of ametropia and psychological problems warrants further study.

Using Web-Based and Paper-Based Questionnaires for Collecting Data on Fertility Issues Among Female Childhood Cancer Survivors: Differences in Response Characteristics  

PubMed Central

Background Web-based questionnaires have become increasingly popular in health research. However, reported response rates vary and response bias may be introduced. Objective The aim of this study was to evaluate whether sending a mixed invitation (paper-based together with Web-based questionnaire) rather than a Web-only invitation (Web-based questionnaire only) results in higher response and participation rates for female childhood cancer survivors filling out a questionnaire on fertility issues. In addition, differences in type of response and characteristics of the responders and nonresponders were investigated. Moreover, factors influencing preferences for either the Web- or paper-based version of the questionnaire were examined. Methods This study is part of a nationwide study on reproductive function, ovarian reserve, and risk of premature menopause in female childhood cancer survivors. The Web-based version of the questionnaire was available for participants through the Internet by means of a personalized user name and password. Participants were randomly selected to receive either a mixed invitation (paper-based questionnaire together with log-in details for Web-based questionnaire, n = 137) or a Web-only invitation (log-in details only, n = 140). Furthermore, the latter group could request a paper-based version of the questionnaire by filling out a form. Results Overall response rates were comparable in both randomization groups (83% mixed invitation group vs 89% in Web-only invitation group, P = .20). In addition, participation rates appeared not to differ (66% or 90/137, mixed invitation group vs 59% or 83/140, Web-only invitation group, P =.27). However, in the mixed invitation group, significantly more respondents filled out the paper-based questionnaire compared with the Web-only invitation group (83% or 75/90 and 65% or 54/83, respectively, P = .01). The 44 women who filled out the Web-based version of the questionnaire had a higher educational level than the 129 women who filled out the paper-based version (P = .01). Furthermore, the probability of filling out the Web-based questionnaire appeared to be greater for women who were allocated to the Web-only invitation group (OR = 2.85, 95% CI 1.31 - 6.21), were older (OR = 1.08, 95% CI 1.02 - 1.15), had a higher educational level (OR high vs low = 0.06, 95% CI 0.01 - 0.52), or were students (OR employed vs student = 3.25, 95% CI 1.00 - 10.56). Conclusions Although overall response as well as participation rates to both types of invitations were similar, adding a paper version of a questionnaire to a Web-only invitation resulted in more respondents filling out the paper-based version. In addition, women who were older, had a higher level of education, or were students, were more likely to have filled out the Web-based version of the questionnaire. Given the many advantages of Web-based over paper-based questionnaires, researchers should strongly consider using Web-based questionnaires, although possible response bias when using these types of questionnaires should be taken into account.

Role of religion and spirituality in medical patients: Confirmatory results with the SpREUK questionnaire  

PubMed Central

Background Spirituality has become a subject of interest in health care as it is was recognized to have the potential to prevent, heal or cope with illness. There is less doubt that values and goals are important contributors to life satisfaction, physical and psychological health, and that goals are what gives meaning and purpose to people's lives. However, there is as yet but limited understanding of how patients themselves view the impact of spirituality on their health and well-being, and whether they are convinced that their illness may have "meaning" to them. To raise these questions and to more precisely survey the basic attitudes of patients with severe diseases towards spirituality/religiosity (SpR) and their adjustment to their illness, we developed the SpREUK questionnaire. Methods In order to re-validate our previously described SpREUK instrument, reliability and factor analysis of the new inventory (Version 1.1) were performed according to the standard procedures. The test sample contained 257 German subjects (53.3 ± 13.4 years) with cancer (51%), multiple sclerosis (24%), other chronic diseases (16%) and patients with acute diseases (7%). Results As some items of the SpREUK construct require a positive attitude towards SpR, these items (item pool 2) were separated from the others (item pool 1). The reliability of the 15-item the construct derived from the item pool 1 respectively the 14-item construct which refers to the item pool 2 both had a good quality (Cronbach's alpha = 0.9065 resp. 0.9525). Factor analysis of item pool 1 resulted in a 3-factor solution (i.e. the 6-item sub-scale 1: "Search for meaningful support"; the 6-item sub-scale 2: "Positive interpretation of disease"; and the 3-item sub-scale 3: "Trust in external guidance") which explains 53.8% of variance. Factor analysis of item pool 2 pointed to a 2-factor solution (i.e. the 10-item sub-scale 4: "Support in relations with the External life through SpR" and the 4-item sub-scale 5: "Support of the Internality through SpR") which explains 58.8% of variance. Generally, women had significantly higher SpREUK scores than male patients. Univariate variance analyses revealed significant associations between the sub-scales and SpR attitude and the educational level. Conclusions The current re-evaluation of the SpREUK 1.1 questionnaire indicates that it is a reliable, valid measure of distinct topics of SpR that may be especially useful of assessing the role of SpR in health related research. The instrument appears to be a good choice for assessing a patients interest in spiritual concerns which is not biased for or against a particular religious commitment. Moreover it addresses the topic of "positive reinterpretation of disease" which seems to be of outstanding importance for patients with life-changing diseases.

Determinants of response to a parent questionnaire about development and behaviour in 3 year olds: European multicentre study of congenital toxoplasmosis  

PubMed Central

Background We aimed to determine how response to a parent-completed postal questionnaire measuring development, behaviour, impairment, and parental concerns and anxiety, varies in different European centres. Methods Prospective cohort study of 3 year old children, with and without congenital toxoplasmosis, who were identified by prenatal or neonatal screening for toxoplasmosis in 11 centres in 7 countries. Parents were mailed a questionnaire that comprised all or part of existing validated tools. We determined the effect of characteristics of the centre and child on response, age at questionnaire completion, and response to child drawing tasks. Results The questionnaire took 21 minutes to complete on average. 67% (714/1058) of parents responded. Few parents (60/1058) refused to participate. The strongest determinants of response were the score for organisational attributes of the study centre (such as direct involvement in follow up and access to an address register), and infection with congenital toxoplasmosis. Age at completion was associated with study centre, presence of neurological abnormalities in early infancy, and duration of prenatal treatment. Completion rates for individual questions exceeded 92% except for child completed drawings of a man (70%), which were completed more by girls, older children, and in certain centres. Conclusion Differences in response across European centres were predominantly related to the organisation of follow up and access to correct addresses. The questionnaire was acceptable in all six countries and offers a low cost tool for assessing development, behaviour, and parental concerns and anxiety, in multinational studies.

Methods Total 126 patients with GERD symptoms were diagnosed as EE (n = 62), NERD (n = 34) and FH (n = 30) by endoscopy, 24-hour esophageal pH testing and Bernstein test, prospectively. Analysis of risk factors and GIS questionnaire for GERD symptoms and quality of life were performed before and 8 weeks after PPI treatment. Results EE group had a higher proportion of men, frequent alcohol consumption, smoking, hiatal hernia, body mass index ? 25 kg/m2 and triglyceride levels (? 150 mg/dL) than the other groups (all P < 0.05). On the other hand, both psychiatric treatment and psychopharmacotherapy were more frequent in patients with FH than in those with EE and NERD (both P < 0.05). Among GERD symptoms, chest pain was more frequent in FH group than in EE and NERD groups (P < 0.05). Eating problems and limitation of productive daily activities occurred frequently in FH group and NERD group, respectively. GIS after 8 week PPI treatment showed improvement in all of the GERD symptoms in EE (all P < 0.05) and in acid regurgitation, epigastric pain and hoarseness in NERD group (all P < 0.05). In terms of quality of life, PPI treatment improved sleep disturbance in EE (P = 0.031) and limitation of productive activity in the NERD group (P = 0.001). Conclusions GIS questionnaire showed that different characteristics and symptoms improved after PPI therapy among patients with EE, NERD and FH, demonstrating the usefulness of the GIS questionnaire.

Self-reported injuries among seafarers. Questionnaire validity and results from an international study.  

PubMed

International surveys of occupational injuries among seafarers have so far been missing. It was the aim to test the method of self-report of injuries and length of time at risk during the latest duty period and second to study the injury incidence rate among seafarers by use of the method. A pilot study was conducted (n = 1068) in Finland, Denmark, the Philippines, Croatia and Spain using self-completed questionnaires with questions about the person, the ship, the duration of latest duty period and injuries. The duration of the self-reporting duty period was in the Danish part compared with information from the crew register of the Maritime Authority. For seafarers from merchant ships in the Danish sub-study there was acceptable correspondence between the information from the seafarers and the Maritime Authority, but not when referring to ferries and non-specified types of ship. Unadjusted and adjusted injury incidence rates-ratios (IRRs) based on number of injuries per number of work hours were calculated. Adjusted IRRs for ordinary seamen/officers: IRR = 2.43 (95% CI: 1.25-4.72); for age < 35/35+ years: IRR = 1.97 (1.02-3.81); length of tour: 117 days or longer compared with < 117 days: IRR = 0.46 (95% CI: 0.22-0.95); 57-70 working hours per week compared with < 57 h: IRR = 1.26 (0.48-3.29), 71+h compared with < 57 h: IRR = 2.12 (0.84-5.36). Non-significant IRRs >1.00 were found for ships under 10,000 GT compared with larger ships and for own flagged ships compared with ships under flag of convenience. In conclusion, more than 70 h of work per week was related to a higher rate of injuries for seafarers on merchant ships, but the result was not statistically significant. Self-report of the duration of the latest tour of duty is useful for seafarers from merchant ships with short-term employments, but not for ferries and other, non-specified types of ship with other or permanent employment.

Schizotypy and hemispheric asymmetry: Results from two Chapman scales, the O-LIFE questionnaire, and two laterality measures.  

PubMed

Schizotypy is a multidimensional personality construct representing the extension of psychosis-like traits into the general population. Schizotypy has been associated with attenuated expressions of many of the same neuropsychological abnormalities as schizophrenia, including atypical pattern of functional hemispheric asymmetry. Unfortunately the previous literature on links between schizotypy and hemispheric asymmetry is inconsistent, with some research indicating that elevated schizotypy is associated with relative right over left hemisphere shifts, left over right hemisphere shifts, bilateral impairments, or with no hemispheric differences at all. This inconsistency may result from different methodologies, scales, and/or sex proportions between studies. In a within-participant design we tested for the four possible links between laterality and schizotypy by comparing the relationship between two common self-report measures of multidimensional schizotypy (the O-LIFE questionnaire, and two Chapman scales, magical ideation and physical anhedonia) and performance in two computerised lateralised hemifield paradigms (lexical decision, chimeric face processing) in 80 men and 79 women. Results for the two scales and two tasks did not unequivocally support any of the four possible links. We discuss the possibilities that a link between schizotypy and laterality (1) exists but is subtle, probably fluctuating, unable to be assessed by traditional methodologies used here; (2) does not exist, or (3) is indirect, mediated by other factors (e.g., stress-responsiveness, handedness, drug use) whose influences need further exploration.

Prescription stimulant expectancies in recreational and medical users: results from a preliminary expectancy questionnaire.  

PubMed

Given the rise of prescription stimulant misuse, examination of effect expectancies could prove helpful. The Prescription Stimulant Expectancy Questionnaire (PSEQ) was designed to explore positive and negative prescription stimulant-related expectancies. In 2006, 157 participants nationwide completed an Internet survey of prescription stimulant use, attention-deficit/hyperactivity disorder symptoms, and expectancies. Multiple regressions demonstrate that positive, but not negative expectancies, predicted frequency of use. Recreational and medical users were classified by hierarchical cluster analysis. Recreational users reported fewer positive and negative expectancies than medical users. Implications and limitations are discussed. Future research is warranted on prescription stimulant expectancies and the utility of the PSEQ. PMID:19938932

Validation of the Intestinal Part of the Prostate Cancer Questionnaire 'QUFW94': Psychometric Properties, Responsiveness, and Content Validity  

SciTech Connect

Purpose: Several treatment options are available for patients with prostate cancer. Applicable and valid self-assessment instruments for assessing health-related quality of life (HRQOL) are of paramount importance. The aim of this study was to explore the validity and responsiveness of the intestinal part of the prostate cancer-specific questionnaire QUFW94. Methods and Materials: The content of the intestinal part of QUFW94 was examined by evaluation of experienced clinicians and reviewing the literature. The psychometric properties and responsiveness were assessed by analyzing HRQOL data from the randomized study Scandinavian Prostate Cancer Group 7 (SPCG)/Swedish Association for Urological Oncology 3 (SFUO). Subscales were constructed by means of exploratory factor analyses. Internal consistency was assessed by Cronbach's alpha. Responsiveness was investigated by comparing baseline scores with the 4-year posttreatment follow-up. Results: The content validity was found acceptable, but some amendments were proposed. The factor analyses revealed two symptom scales. The first scale comprised five items regarding general stool problems, frequency, incontinence, need to plan toilet visits, and daily activity. Cronbach's alpha at 0.83 indicated acceptable homogeneity. The second scale was less consistent with a Cronbach's alpha at 0.55. The overall responsiveness was found to be very satisfactory. Conclusion: Two scales were identified in the bowel dimension of the QUFW94; the first one had good internal consistency. The responsiveness was excellent, and some modifications are suggested to strengthen the content validity.

Primary care providers' knowledge, beliefs and treatment practices for gout: results of a physician questionnaire.  

PubMed

Objective. We sought to examine primary care providers' gout knowledge and reported treatment patterns in comparison with current treatment recommendations. Methods. We conducted a national survey of a random sample of US primary care physicians to assess their treatment of acute, intercritical and tophaceous gout using published European and American gout treatment recommendations and guidelines as a gold standard. Results. There were 838 respondents (response rate of 41%), most of whom worked in private practice (63%) with >16 years experience (52%). Inappropriate dosing of medications in the setting of renal disease and lack of prophylaxis when initiating urate-lowering therapy (ULT) accounted for much of the lack of compliance with treatment recommendations. Specifically for acute podagra, 53% reported avoidance of anti-inflammatory drugs in the setting of renal insufficiency, use of colchicine at a dose of ?2.4 mg/day and no initiation of a ULT during an acute attack. For intercritical gout in the setting of renal disease, 3% would provide care consistent with the recommendations, including initiating a ULT at the appropriate dose with dosing titration to a serum urate level of ?6 mg/dl and providing prophylaxis. For tophaceous gout, 17% reported care consistent with the recommendations, including ULT use with dosing titration to a serum urate level of ?6 mg/dl and prophylaxis. Conclusion. Only half of primary care providers reported optimal treatment practices for the management of acute gout and <20% for intercritical or tophaceous gout, suggesting that care deficiencies are common.

The responsiveness of the uterine fibroid symptom and health-related quality of life questionnaire (UFS-QOL)  

PubMed Central

Background A number of noninvasive alternatives to hysterectomy have become available as treatments for uterine fibroids. These alternative therapies, however, may not relieve all symptoms. Consequently, the need for patient-reported outcomes to assess symptom reduction of uterine fibroids has become increasingly important to evaluate the clinical success of patients who choose these alternative therapies. The purpose of the study was to examine the responsiveness of the Uterine Fibroid Symptom and Health-Related Quality of Life Questionnaire (UFS-QOL) with treatment of uterine fibroids. Methods The responsiveness of the UFS-QOL was assessed as a post-hoc analysis of patients treated with MRI-guided focused ultrasound thermal ablation (MRgFUS) for uterine fibroids. The UFS-QOL and SF-36 were completed at baseline and months 1, 3, and 6. Patient perceived overall treatment effect (OTE) was assessed at month 3, while satisfaction with treatment was collected at month 6. The responsiveness of the UFS-QOL was examined using effect sizes and change scores by patient-reported overall treatment effect and satisfaction. Results A total of 102 women with complete UFS-QOL data were included in the analysis; the mean age was 45 years and 79% were Caucasian. From baseline to 6 months, significant improvements were observed in UFS-QOL Symptom Severity and all Health-Related Quality of Life (HRQL) subscale scores (p < 0.0001). When examining change in general health status over the 6-month follow-up period, significant improvements were noted in all 8 SF-36 subscales. The UFS-QOL was highly responsive with subscale effect sizes ranging from 0.74 for Sexual Function to -1.9 for Symptom Severity. Improvements in UFS-QOL subscales were associated with patient perceptions of perceived benefit and treatment satisfaction. Conclusion The UFS-QOL is responsive to treatment for uterine fibroids and is a useful outcome measure for uterine-sparing uterine fibroid treatments.

High incidence of sleep problems in children with developmental disorders: Results of a questionnaire survey in a Japanese elementary school.  

PubMed

Objective: The aim of the present school-based questionnaire was to analyze the sleep problems of children with developmental disorders, such as pervasive developmental disorder and attention deficit hyperactivity disorder. Methods: The sleep problems of 43 children with developmental disorders were compared with those of 372 healthy children (control group). All children attended one public elementary school in Kurume, Japan; thus, the study avoided the potential bias associated with hospital-based surveys (i.e. a high prevalence of sleep disturbance) and provided a more complete picture of the children's academic performance and family situation compared with a control group under identical conditions. Children's sleep problems were measured with the Japanese version of the Children's Sleep Habits Questionnaire (CSHQ). Results: Children with developmental disorders had significantly higher total CSHQ scores, as well as mean scores on the parasomnias and sleep breathing subscales, than children in the control group. The total CSHQ score, bedtime resistance, sleep onset delay, and daytime sleepiness worsened with increasing age in children with developmental disorders; in contrast, these parameters were unchanged or became better with age in the control group. In children with developmental disorders, there was a significant association between a higher total CSHQ score and lower academic performance, but no such association was found in the control group. For both groups, children's sleep problems affected their parents' quality of sleep. There were no significant differences in physical, lifestyle, and sleep environmental factors, or in sleep/wake patterns, between the two groups. Conclusions: Children with developmental disorders have poor sleep quality, which may affect academic performance. It is important for physicians to be aware of age-related differences in sleep problems in children with developmental disorders. Further studies are needed to identify the association between sleep quality and school behavioral performance. PMID:23305729

Toilet Training in Healthy Children: Results of a Questionnaire Study Involving Parents Who Make Use of Day-Care at Least Once a Week.  

PubMed

AIMS: To investigate how toilet training (TT) is dealt with and what the associated feelings are in Flemish families using day-care at least once a week. METHODS: A questionnaire was provided to 256 parents of healthy children between 15 and 35 months old, using day-care every week. Data were analyzed using SPSS18.0. RESULTS: Two hundred twenty-two questionnaires were completed (response rate: 87%), of which 221 were valid. The overall results show that the start of TT and method used are mainly in line with current recommendations, and that the cooperation between parents and day-care is seen as positive, providing support for the parents in guiding their child in the TT-process. Most parents (74%) stated that day-care and parents should play an equal role in the TT-process. However, 17% of the parents experienced uncertainty, stress, and/or frustration related to TT. This percentage increased to 30% when asked about the right moment to start TT. Moreover, 18% of the parents reported a lack of time to guide their child in the TT-process. Eighteen percent of the parents agreed that responsibility for TT is increasingly passed on to day-care, while 46% remained undecided. In addition, 40% of the parents had no idea whether they used the same TT method as the day-care center. CONCLUSIONS: The results, in general, reflect a positive image of how TT is dealt with. However, several concerns were raised about the shared TT between parents and day-care, implying that further research on this topic is needed. Neurourol. Urodynam. © 2013 Wiley Periodicals, Inc.

The post-investigation questionnaire (PIO-R): a practical instrument to assess erectile response after intracavernous injection.  

PubMed

Erectile response to intracavernous pharmacological stimulation is highly susceptible to stress and anxiety provoked by the test-situation. To reduce false-positive diagnosis of veno-occlusive dysfunction and to limit the need for high-dosage pharmacotesting, we developed the Post-Investigation Questionnaire (PIQ-R), a self-report instrument to assess erectile response to pharmacological stimulation after the patient has left the office. In this study veno-occlusive sufficiency was not demonstrated in 80 of 105 patients with erectile dysfunction at the time of pharmaco-penile duplex ultrasonography. PIQ-R detected sufficient erectile response in 40 of these patients, thus reducing false-positive diagnosis of veno-occlusive dysfunction by 50%. We also found that reports of sexual activity after investigation increased interest in auto-injection therapy. PIQ-R is a practical self-report measure to assess erectile response after clinical pharmacotesting, and to more carefully select patients for auto-injection therapy. PMID:8858391

[Results of a questionnaire about smoking distributed at the 36th annual meeting of the Japan Society of Chest Diseases].  

PubMed

To gather data about smoking habits among members of the Japan Society of Chest Diseases, a questionnaire was distributed during the 36th annual meeting. A total of 2411 out of 3725 questionnaires were returned (65%). The percentage of smokers was 23%. Smoking was prohibited in the hospitals of 281 respondents (8%). Seventy-nine percent reported that patients smoking areas were separated from patients' non-smoking areas, but only 41% reported that physicians' smoking areas were separated from physicians' non-smoking areas. Tobacco was being solid in over 50% of the hospitals represented, either via vending machines or through hospital retail stores. However, 79% of the respondents indicated that hospitals should be smoke-free. Questions of ethics in medicine are highlighted by this questionnaire. The obvious issues involved are whether or nor both patients and physicians should be required to stop smoking in health-care facilities. The larger issue is the degree and method by which the Japan Society of Chest Diseases should involve itself actively in smoking reform for the sake of society in general. PMID:9366160

Development and psychometric evaluation of a new measure of pain-related support preferences: The Pain Response Preference Questionnaire  

PubMed Central

BACKGROUND: Behavioural conceptualizations of chronic pain posit that solicitous responses to pain behaviours are positively reinforcing and play a role in the development of chronic pain and disability. Recent research suggests that studies investigating this model were likely limited by the use of only a few narrowly defined categories of responses to pain behaviour. A measure of preferences regarding pain-related social support has the potential to improve behavioural models of chronic pain by identifying other potentially reinforcing responses to pain behaviour. OBJECTIVE: The Pain Response Preference Questionnaire (PRPQ) was created to assess preferences regarding pain-related social support. The purpose of the present study was to empirically develop PRPQ scales and examine their psychometric properties. METHODS: A large university student sample (n=487) free of chronic pain completed the 39-item PRPQ. Factor analysis was applied to the data from the present sample to empirically develop PRPQ scales. Using a second student sample (n=87), relationships between the PRPQ scales and theoretically related measures were examined to evaluate the construct validity of the scales. Factor analysis supported four factors that reflected preferences for emotional and instrumental support, assistance in managing pain and emotions, having one’s pain ignored, and being encouraged to persist with one’s activities. Based on this analysis, scales labelled solicitude, management, suppression and encouragement were created. Correlation analyses supported the construct validity of these scales. CONCLUSIONS: The PRPQ is a psychometrically sound measure of preferences of pain-related social support. Research with clinical samples is needed to further evaluate its psychometric properties and clinical utility.

Relationship between the Onset of Depression and Stress Response Measured by the Brief Job Stress Questionnaire among Japanese Employees: A Cohort Study  

PubMed Central

Background The proportion of Japanese workers experiencing intense worry or stress during working life is in excess of 60%, and the incidence of psychiatric disorders and suicide due to psychological burden from work duties is increasing. To confirm whether the stress response measured by the Brief Job Stress Questionnaire (BJSQ) can identify risk for depression, a cohort study was conducted to evaluate whether the stress response measured by BJSQ was associated with the onset of depression. Methods A total of 1,810 participants aged 20–70 years in 2005 completed the stress response of the BJSQ and were followed-up until August, 2007 by examining sick pay records. Depression was defined by a description in sick pay records that included “depression” or “depressive symptoms” as a reason for sick leave according to a physician's medical certificate. The participants were divided into quartiles (Ql, Q2, Q3, and Q4) according to the total stress response score of BJSQ at baseline. Furthermore, the participants were divided into a higher score category (Q4) and a lower score category (Q1–Q3). Risk ratios of the stress response of the BJSQ for onset of depression were calculated using a multivariable Cox proportional hazard model. Results Among 1,810 participants, 14 developed depression during a mean of 1.8 years of follow-up. The risk ratio was 2.96 (95% confidence interval [CI], 1.04–8.42, p for trend?=?0.002) when the higher stress response score category of BJSQ was compared with the low stress response score category for sick leave due to depression. After adjusting for gender, age, marital status, and having children, the risk ratios were similar to no adjustment. Conclusions These findings suggest that the stress response measured by the BJSQ can demonstrate risk for the onset of depression.

Nephrology quiz and questionnaire: transplantation.  

PubMed

Presentation of the Nephrology Quiz and Questionnaire (NQQ) has become an annual "tradition" at the meetings of the American Society of Nephrology. It is a very popular session judged by consistently large attendance. Members of the audience test their knowledge and judgment on a series of case-oriented questions prepared and discussed by experts. They can also compare their answers in real time, using audience response devices, to those of program directors of nephrology training programs in the United States, acquired through an Internet-based questionnaire. Topics presented here include transplantation issues. These cases, along with single best answer questions, were prepared by Dr. Hricik. After the audience responses, the "correct" and "incorrect" answers were then briefly discussed and the results of the questionnaire were displayed. This article aims to recapitulate the session and reproduce its educational value for a larger audience-that of the readers of the Clinical Journal of the American Society of Nephrology. Have fun.

Awareness, attitudes, and perceptions of Croatian-based orthopedic and trauma surgeons toward scientific manuscripts, publishing internationally and medical writing. Results of an online questionnaire.  

PubMed

The objective of this survey was to identify the importance placed by Croatian-based surgeons on writing scientific manuscripts and publishing them internationally, as well as their awareness of and attitudes toward medical writing. A link to an online survey was sent to 327 Croatian-based orthopedic and trauma surgeons. The electronic questionnaire consisted of rating scales, multiple choice questions and free text reply boxes. A total of 61 surgeons based in Croatia replied to the survey, yielding a response rate of 19% (61/327). The survey results indicate that surgeons in Croatia are active in both research and the writing of manuscripts. There is also a high level of interest among them to publish internationally in English to further their careers. While 68% (38/56) of respondents initially claimed to know about medical writing, further questioning on the subject revealed a reduced level of familiarity with the concept. Only 19% (11/58) of respondents had ever engaged the services of a medical writer and they were generally satisfied with the work done across the three areas of language, editing and scientific knowledge. Medical writers are advised to increase awareness of their services among Croatian-based orthopedic and trauma surgeons who may well have a need for their expertise. PMID:23697268

The role of the nurse lecturer in the supervision of students' essays, projects and assignments: results of an all Wales questionnaire survey.  

PubMed

This study explores the role of the lecturer in nursing and midwifery education in the supervision of students' essays, projects and assignments. Three methods were used within the study; semi-structured interviews, questionnaires and focus groups. The results from the semi-structured interviews were used to develop a questionnaire which was distributed to the population of lecturers in nursing and midwifery education (n=285) within Wales. This article reports some of the key findings of the questionnaire survey. Lecturers report a directive style of supervision with a considerable amount of time being invested in the supervision process. The production of guidelines for good supervision practice is recommended as a way of providing consistent and fair supervision for students. PMID:12384031

Survey of construction workers repeatedly exposed to chlorine over a three to six month period in a pulpmill: II. Follow up of affected workers by questionnaire, spirometry, and assessment of bronchial responsiveness 18 to 24 months after exposure ended.  

PubMed Central

OBJECTIVE--The aim was to determine the prevalence of persistent respiratory symptoms and bronchial hyper-responsiveness due to reactive airways dysfunction syndrome in a population of construction workers at moderate to high risk of developing the syndrome, at an interval of 18 to 24 months after multiple exposures to chlorine gas during renovations to a pulp and paper mill. DESIGN AND PARTICIPANTS--71 of 289 exposed workers (25%) were identified on the basis of an exposure and the onset of respiratory symptoms shortly after this event (moderate to high risk). A standardised respiratory questionnaire was first presented, followed by spirometry and a methacholine inhalation test on those whose questionnaire suggested the persistence of respiratory symptoms. RESULTS--64 of 71 (90%) subjects completed the respiratory questionnaire at the time of the follow up. The questionnaire suggested a persistence of respiratory symptoms in 58 of the 64 workers (91%). Of the 58 subjects, 51 underwent spirometry and assessment of bronchial responsiveness. All of them used bronchodilators as required (not regularly) and four required inhaled anti-inflammatory preparations. Sixteen had bronchial obstruction (forced expiratory volume in one second) (FEV1 < 80% predicted) and 29 showed significant bronchial hyper-responsiveness. CONCLUSION--Of the subjects (n = 71) who were at moderate to high risk of developing reactive airways dysfunction syndrome after being exposed to chlorine and were seen 18 to 24 months after exposure ended, 58 (82%) still had respiratory symptoms, 16 (23%) had evidence of bronchial obstruction, and 29 (41%) had bronchial hyper-responsiveness.

Prevalence of undiagnosed abnormal glucose tolerance in adult patients cared for by general practitioners in Hungary. Results of a risk-stratified screening based on FINDRISC questionnaire  

PubMed Central

Background The prevalence of type 2 diabetes mellitus is rapidly increasing, worldwide and also in Hungary. Timely diagnosis and early treatment could be aided by targeted screening. Recognizing this, the Hungarian Diabetes Association initiated a risk-stratified screening with the involvement of primary care physicians. Material/Methods In the first phase of screening, the FINDRISC questionnaire was completed, followed by an oral glucose tolerance test (OGTT) for those with a score of ?12. Between September 1, 2010 and March 31, 2011, 70,432 non-diabetic adults, who visited their general practitioners for any reason, were involved in the screening. Of these, 68,476 questionnaires proved to be suitable for processing. Results From the questionnaires, 28,077 (41.0%) had a score of ?12. A valid OGTT was performed in 22,846 cases; of this group 3,217 subjects (14.1%) had elevated fasting glucose levels, 5,663 (24.8%) had impaired glucose tolerance, and 1,750 (7.6%) had manifest, previously undiagnosed, diabetes mellitus. Overall, from the valid OGTT group, 46.5% subjects had some degree of glucose intolerance. Conclusions Based on the FINDRISC questionnaire, the risk-stratified screening for diabetes mellitus proved to be simple and cost-effective method for the early detection of carbohydrate metabolism disorders. Using this method, the prevalence rate of previously undiagnosed abnormal glucose tolerance was high in adult patients cared for by general practitioners in Hungary.

[Results of psychometric and questionnaire methods in the evaluation of noise and vibration on floating oil rigs in the Caspian sea].  

PubMed

A psychometric study of noise and vibration was performed at different parts of the Caspian floating oil rigs. The analysis of 500 questionnaires received from the personnel showed that the correlation coefficients for different values, depending on the parameters of the levels, were 0.71-0.87 for noise and 0.33-0.44 for vibration. The noise levels calculated for oil workers of different professions, were: in cabins, recreation rooms and working sites 40-52, 57-63 and 73-74 dBA respectively, and the comparative vibration rate levels were 67-74, 79-85 and 90-97 dB, respectively. 273 questionnaires revealed that the acoustic conditions in the abins affected both the process of falling asleep and depth of sleep (correlation coefficients 0.88 and 0.93, respectively). Noise levels at 30-36 dBA did not cause any sleep discomfort. 84% questionnaires contained in average 3.5 complaints, with the maximum 5.2 complaints for the machine operators, and the minimum 3.2 complaints for the electricians who worked in acoustically more favorable conditions. The study proved that the psychometric and questionnaire data in 70% cases corresponded to the results of the laboratory techniques, such as audiometry, chronoreflexometry, tono- and pulsometry, electrocardiometry, etc. The research data received served a basis for noise and vibration hygienic norming in floating oil-rig sites.

Use of the Italian version of the Pediatric Asthma Quality of Life Questionnaire in the daily practice: results of a prospective study  

PubMed Central

Background Asthma is a serious global health problem and its prevalence is increasing, especially among children. It represents a significant social and economic burden, and it can severely affect the health-related quality of life (HRQL) of patients. Among the numerous questionnaires aiming at evaluating asthma HRQL in children, the Pediatric Asthma Quality of Life Questionnaire (PAQLQ) has proved to have good measurement properties. The present study was aimed at investigating the possible role of the Italian, self-administered version of the PAQLQ in the routine clinical evaluation of children affected by bronchial asthma. Methods 52 Italian children and adolescents (40 males and 12 females), aged 6 to 17 years, affected by allergic asthma, were enrolled. Each patient was evaluated twice, and at each visit asthma control and severity were assessed, spirometry was performed and the patients completed the self-administered version of the PAQLQ. Results The questionnaire was well-accepted and understood by the children. Children showed an overall good quality of life, with mild impairment in the activity and emotional function domains. The PAQLQ showed an overall good correlation with the clinical and functional indexes that are normally evaluated in follow-up visits of asthmatic patients. The PAQLQ appeared to be strongly related to asthma control, both at the first (p < 0.01) and second (p < 0.001) time of the study. The PAQLQ was also seen to decrease with increasing asthma severity. The results suggest a better compliance of the children towards completion of the questionnaire at t1. Finally, the PAQLQ does not appear to discriminate HRQL in patients with good lung function. Conclusion The Italian version of the PAQLQ is a quick-to-administer aid to clinical activity and can add valuable information to symptom reports, objective measurements and clinical assessment of asthma control and severity in daily clinical practice. Re-administration at each follow-up visit allows HRQL to be monitored over time.

Parental authority questionnaire.  

PubMed

A questionnaire was developed for the purpose of measuring Baumrind's (1971) permissive, authoritarian, and authoritative parental authority prototypes. It consists of 30 items per parent and yields permissive, authoritarian, and authoritative scores for both the mother and the father; each of these scores is derived from the phenomenological appraisals of the parents' authority by their son or daughter. The results of several studies have supported the Parental Authority Questionnaire as a psychometrically sound and valid measure of Baumrind's parental authority prototypes, and they have suggested that this questionnaire has considerable potential as a valuable tool in the investigation of correlates of parental permissiveness, authoritarianism, and authoritativeness.

[The state of antimicrobial prophylaxis for holmium laser enucleation of the prostate : HoLEP and the results of a questionnaire survey].  

PubMed

Holmium laser enucleation of the prostate (HoLEP) has been established as a procedure for the treatment of patients with benign prostate hyperplasia, instead of transurethral resection of prostate (TURP). To determine the appropriate antimicrobial prophylaxis for the prevention of perioperative urinary tract infection following HoLEP we sent a questionnaire to 79 institutes belonging to the Japanese Urological Association. We surveyed 1) the performance of HoLEP, 2) number of HoLEP performed in 2009, 3) antimicrobial agents and the term of the administration for prophylaxis, 4) rate of perioperative infections, and 5) usage of other antimicrobial prophylaxis in HoLEP, as compared with in TUR-P. We received answers from 59 institutes (74. 9%). We examined 43 responses, which were obtained from executive members who performed more than eleven cases of HoLEP in 2009. Thirty-one of these institutes (72.1%) indicated parenteral antibiotics ; three of them adopted oral antibiotics, and nine of them added oral antibiotics following parenteral antibiotics. In 40 of them (93.0%), the rate of perioperative infections was reported to be fewer than 5%. Twenty-seven of them (62. 7%) adopted the same schedule for the prophylaxis in both HoLEP and TUR-P. Eleven of them indicated shorter antimicrobial usage in HoLEP than in TUR-P. Ten of the eleven institutes reported that the rate of perioperative infections in HoLEP had been lower than in TUR-P. Our questionnaire survey demonstrated that shorter antimicrobial prophylaxis might be possible in HoLEP than in TUR-P. PMID:22089150

Predicting Memory Training Response Patterns: Results From ACTIVE  

PubMed Central

Previous research suggests that there is a great deal of variability among older adults' response to memory training. Using latent class analysis, we examined data from the memory training arm of the Advanced Cognitive Training for Independent and Vital Elderly Trial (ACTIVE), a large randomized controlled cognitive training trial, to determine if there were distinct patterns of responsiveness to training. Additionally, we examined whether baseline demographic and cognitive factors were predictive of these response patterns. The results indicate that among memory-trained participants, there are 3 distinct response patterns, suggesting that participants gravitate toward specific mnemonic techniques. Furthermore, baseline memory and speed of processing abilities, age, and education are predictive of these distinct response patterns. Taken together, the findings suggest that we can characterize and predict older adults' response to memory training.

Knowledge, attitudes and decision-making in Czech women with atypical results of prenatal screening tests for the most common chromosomal and morphological congenital defects in the fetus: Selected questionnaire results.  

PubMed

AIMS: The primary aim was to investigate variables affecting compliance in pregnant women recommended for genetic consultation for abnormal screening test results, family predisposition or medical history. Our main focus was on a women's knowledge of particular screening tests, their initial feelings and changes in these feeling with time, as well as variables relevant to further decision making. METHODS: We used an anonymous questionnaire based on previous qualitative research. The questions were formulated by a medical geneticist, and the questionnaires were distributed prior to prenatal screening tests performed by doctors or trained nurses. The research cohort consisted of 271 women aged 16-42 years. Six hypotheses were tested using the statistical programme STATISTICA; significance levels were set to P<0.05. RESULTS: The questionnaire results showed insufficient knowledge. The women were confused about invasive, screening and ultrasound tests. Genetic test recommendation was largely associated with stress in these patients. Between recommendation and consultation, the women mostly looked for support from their partners. There was a surprisingly low percentage of women who looked for help from their medical specialists and a surprisingly high percentage of those who did not seek any help at all. CONCLUSION: Women's distress can be reduced if the information about recommended genetic consultation is conveyed correctly and this can also help them make the right informed decision about their future course of action.

[Dimensions of parental rearing styles in alcohol dependent patients: first results of the questionnaire on parental attitudes and rearing practices (FEPS)].  

PubMed

To date no instrument for the assessment of parenting styles is available in the German -language area that has been validated in patients with addictive disorders. Therefore the aim of this study was the confirmatory evaluation of the factor structure of the Questionnaire on Parental Attitudes and Rearing Practices (FEPS) in 186 alcohol dependent patients. The model as proposed by the test developers with the 4 factors Care, Autonomy, Low Punishment, and Low Material Reinforcement showed acceptable fit when residual correlations were allowed (mother: ?(2)/df=1,92, RMSEA=0,07, TLI=0,79; father: ?(2)/df=1,75, RMSEA=0,07, TLI=0,82). All factors showed sufficient factor reliabilities as well as good to very good internal consistencies.

Self-selection biases in correlational studies based on questionnaires

It is commonly held that even where questionnaire response is poor, correlational studies are affected only by loss of degrees of freedom or precision. We show that this supposition is not true. If the decision to respond is correlated with a substantive variable of interest, then regression or analysis of variance methods based upon the questionnaire results may be adversely

Presentation of the Nephrology Quiz and Questionnaire has become an annual tradition at the meetings of the American Society of Nephrology. It is a very popular session judged by consistently large attendance. Members of the audience test their knowledge and judgment on a series of case-oriented questions prepared and discussed by experts. They can also compare their answers in real time using audience response devices with the answers of program directors of nephrology training programs in the United States through an Internet-based questionnaire. Topics presented here include fluid and electrolyte disorders, transplantation, and ESRD and dialysis. Cases representing each of these categories along with single best-answer questions were prepared by a panel of experts (the authors). The correct and incorrect answers then were briefly discussed after the audience responses and the results of the questionnaire were displayed. This article tries to recapitulate the session and reproduce its educational value for a larger audience-the readers of the Clinical Journal of the American Society of Nephrology. Have fun.

Asthma and allergic disease prevalence in a diverse sample of Toronto school children: Results from the Toronto Child Health Evaluation Questionnaire (T-CHEQ) Study  

PubMed Central

BACKGROUND: Asthma is the most common chronic disease in children. OBJECTIVES: To describe the prevalence of asthma and allergic disease in a multiethnic, population-based sample of Toronto (Ontario) school children attending grades 1 and 2. METHODS: In 2006, the Toronto Child Health Evaluation Questionnaire (T-CHEQ) used the International Study of Asthma and Allergies in Childhood survey methodology to administer questionnaires to 23,379 Toronto school children attending grades 1 and 2. Modifications were made to the methodology to conform with current privacy legislation and capture the ethnic diversity of the population. Lifetime asthma, wheeze, hay fever and eczema prevalence were defined by parental report. Asthma was considered to be current if the child also reported wheeze or asthma medication use in the previous 12 months. RESULTS: A total of 5619 children from 283 randomly sampled public schools participated. Children were five to nine years of age, with a mean age of 6.7 years. The overall prevalence of lifetime asthma was 16.1%, while only 11.3% had current asthma. The reported prevalence of lifetime wheeze was 29.2%, while 14.2% reported wheeze in the past 12 months. Sociodemographic and major health determinant characteristics of the T-CHEQ population were similar to 2001 census data, suggesting a diverse sample that was representative of the urban childhood population. CONCLUSIONS: Asthma continues to be a highly prevalent chronic disease in Canadian children. A large proportion of children with reported lifetime asthma, who were five to nine years of age, did not report current asthma symptomatology or medication use.

Engagement of patients in religious and spiritual practices: Confirmatory results with the SpREUK-P 1.1 questionnaire as a tool of quality of life research  

PubMed Central

Background Quality of life is a multidimensional construct composed of functional, physical, emotional, social and spiritual well-being. In order to examine how patients with severe diseases view the impact of spirituality and religiosity on their health and how they cope with illness, we have developed the SpREUK questionnaire. We deliberately avoided the intermingling of attitudes, convictions and practices, and thus addressed the distinct forms and frequencies of spiritual/religious practices in an additional manual, the SpREUK-P questionnaire. Methods The SpREUK-P was designed to differentiate spiritual, religious, existentialistic and philosophical practices. It was tested in a sample of 354 German subjects (71% women; 49.0 ± 12.5 years). Half of them were healthy controls, while among the patients cancer was diagnosed in 54%, multiple sclerosis in 22%, and other chronic diseases in 23%. Reliability and factor analysis of the inventory were performed according to the standard procedures. Results We confirmed the structure and consistency of the previously described 18-item SpREUK-P manual and improved the quality of the current construct by adding several new items. The new 25-item SpREUK-P 1.1 (Cronbach's alpha = 0.8517) has the following scales: (1) conventional religious practice (CRP), (2) existentialistic practice (ExP), (3) unconventional spiritual practice (USP), (4) nature/environment-oriented practice (NoP), and (5) humanistic practice (HuP). Among the tested individuals, the highest engagement scores were found for HuP and NoP, while the lowest were found for the USP. Women had significantly higher scores for ExP than male patients. With respect to age, the engagement in CRP increases with increasing age, while the engagement in a HuP decreased. Individuals with a Christian orientation and with a religious and spiritual attitude had the highest engagement scores for CRP, while the engagement in an USP was high with respect to a spiritual attitude. Variance analyses confirmed that the SpR attitude and religious affiliation are the main relevant covariates for CRP and ExP, while for the USP the SpR attitude and the educational level are of significance, but not religious affiliation. Patients with multiple sclerosis overall had the lowest engagement scores for all five forms of SpR practice, while it is remarkable that cancer patients had lower scores for HuP and USP than healthy subjects. Conclusion The current re-evaluation of the SpREUK-P questionnaire (Version 1.1) indicates that it is a reliable, valid measure of five distinct forms of spiritual, religious and philosophical practice that may be especially useful for assessing the role of spirituality and religiosity in health related research. An advantage of our instruments is the clear-cut differentiation between convictions and attitudes on the one hand, and the expression of these attitudes in a concrete engagement on the other hand.

Utility of the social communication questionnaire-current and social responsiveness scale as teacher-report screening tools for autism spectrum disorders.  

PubMed

Limited research exists regarding the role of teachers in screening for Autism Spectrum Disorders (ASD). The current study examined the use of the Social Communication Questionnaire (SCQ) and Social Responsiveness Scale (SRS) as completed by parents and teachers about school-age children from the Simons Simplex Collection. Using the recommended cutoff scores in the manuals and extant literature, the teacher-completed SCQ and SRS yielded lower sensitivity and specificity values than would be desirable; however, lowering the cutoff scores on both instruments improved sensitivity and specificity to more adequate levels for screening purposes. Using the adjusted cutoff scores, the SRS teacher form appears to be a slightly better screener than the SCQ. Implications and limitations are discussed, as well as areas for future research.

Current test results for the Athena radar responsive tag  

NASA Astrophysics Data System (ADS)

Sandia National Laboratories has teamed with General Atomics and Sierra Monolithics to develop the Athena tag for the Army's Radar Tag Engagement (RaTE) program. The radar-responsive Athena tag can be used for Blue Force tracking and Combat Identification (CID) as well as data collection, identification, and geolocation applications. The Athena tag is small (~4.5" x 2.4" x 4.2"), battery-powered, and has an integral antenna. Once remotely activated by a Synthetic Aperture Radar (SAR) or Moving Target Indicator (MTI) radar, the tag transponds modulated pulses to the radar at a low transmit power. The Athena tag can operate Ku-band and X-band airborne SAR and MTI radars. This paper presents results from current tag development testing activities. Topics covered include recent field tests results from the AN/APY-8 Lynx, F16/APG-66, and F15E/APG-63 V(1) radars and other Fire Control radars. Results show that the Athena tag successfully works with multiple radar platforms, in multiple radar modes, and for multiple applications. Radar-responsive tags such as Athena have numerous applications in military and government arenas. Military applications include battlefield situational awareness, combat identification, targeting, personnel recovery, and unattended ground sensors. Government applications exist in nonproliferation, counter-drug, search-and-rescue, and land-mapping activities.

Development of an objective questionnaire to assess perception, concern, and knowledge of, and attention and response to, the threat of nuclear war  

SciTech Connect

In addition to the subject objective, the relationship of specified personality variables (i.e., trait anxiety, locus of control, response tendency towards threat, and denial) to behavioral and psychological responses to the threat of nuclear war were assessed. The quantitative questionnaire, titled the Nuclear Reaction Scale, was composed of items selected from issues discussed in the psychological literature on the threat of nuclear war. These issues included: psychic numbing, cognitive reality, perceptions of likelihood and survival, nuclear illusions, and attention to the threat of nuclear war. A standardization sample of 360 college students was administered the Nuclear Reaction Scale, Trait Anxiety Scale, Internal-External Locus of Control Scale, Facilitation-Inhibition Scale, and Haan Denial Scale. Three additional subsamples, identified as Military, Nuclear Freeze, and Church, were given the Nuclear Reaction Scale to assess the validity of the scale. A factor analysis of the Nuclear Reaction Scale indicated a nine-factor solution that described issues such as concern perceptions, likelihood, survivability, and control over the threat of nuclear war. A number of strong relationships existed between computed factors on the Nuclear Reaction Scale. Demographic comparisons found significant differences related to sex and political affiliation.

Biomechanical changes in endothelial cells result from an inflammatory response  

NASA Astrophysics Data System (ADS)

During periods of infection and disease, the immune system induces the release of TNF-?, an inflammatory cytokine, from a variety of cell types, such as macrophages. TNF-?, while circulating in the vasculature, binds to the apical surface of endothelial cells and causes a wide range of biological and mechanical changes to the endothelium. While the biological changes have been widely studied, the biomechanical aspects have been largely unexplored. Here, we investigated the biomechanical changes of the endothelium as a function of TNF-? treatment. First, we studied the traction forces applied by the endothelium, an effect that is much less studied than others. Through the use of traction force microscopy, we found that TNF-? causes an increase in traction forces applied by the endothelial cells as compared to non-treated cells. Then, we investigated cell morphology, cell mechanics, migration, and cytoskeletal dynamics. We found that in addition to increasing applied traction forces, TNF-? causes an increase in cell area and aspect ratio on average, as well as a shift in the organization of F-actin filaments within the cell. Combining these findings together, our results show that an inflammatory response heavily impacts the morphology, cell mechanics, migration, cytoskeletal dynamics, and applied traction forces of endothelial cells.

Evaluation of the psychometric properties of the developmental coordination disorder questionnaire for parents (DCD-Q): results from a community based study of school-aged children.  

PubMed

In this study, we examine several key psychometric properties (reliability, construct validity, concurrent validity) of the Developmental Coordination Disorder Questionnaire (DCD-Q) using a large, school-based sample of children (n=523) and their parents. Children completed the Children's Self-perceptions of Adequacy in and Predilection toward Physical Activity (CSAPPA) and parents completed the DCD-Q. The internal reliability of the DCD-Q was high for both the full scale and the subscales. Confirmatory factor analysis established that the scale was multifactorial, but the fit of the hypothesized factor structure was poor. Finally, moderate correlations were observed between the CSAPPA and the DCD-Q, with the strongest correlation found between the "perceived adequacy" subscale of the CSAPPA and "control during movement" subscale of the DCD-Q. Implications for screening and further research are discussed in relation to both instruments. PMID:18635280

Building consensus on nomenclature and disease classification for ankylosing spondylitis: results and discussion of a questionnaire prepared for the International Workshop on New Treatment Strategies in Ankylosing Spondylitis, Berlin, Germany, 18-19 January 2002  

PubMed Central

Background: There is currently no universal consensus on nomenclature for spondyloarthropathy (SpA), or on activity and severity criteria for ankylosing spondylitis (AS). Method: Points of agreement and majority opinions among 28 international experts in the field were identified by questionnaire. Agreement was defined as >80% concurrence, clear majority as >60% concurrence, and a majority or trend as >50% concurrence. Results: Respondents agreed on the need for one term that reflects the inflammatory nature of the disease, but no agreement was reached on a specific term. Agreement included subdivision of patients with SpA into AS, psoriatic arthritis, inflammatory bowel disease associated arthritis, and undifferentiated spondyloarthritis/spondyloarthropathy. A majority of experts defined active disease as fulfilling classification criteria for AS and/or a SpA, and disease activity measured by a Bath AS Disease Activity Index (BASDAI) score >4 determined by two patient visits during a two month period, but no maximum radiographic score. The majority of participants considered failure of treatment response to non-steroidal anti-inflammatory drugs (NSAIDs) alone to be a prerequisite for active/severe AS, and 15/28 (54%) thought that NSAID treatment failure should be defined as lack of response to two or more NSAIDs. Conclusions: Respondents agreed that a two to five year study is the ethical method to demonstrate effects of anti-tumour necrosis factor ? (TNF?) therapy on radiographic progression of AS, and that inclusion criteria should include a certain level of disease activity (measured by BASDAI) and failure of certain treatments. After the efficacy of anti-TNF? therapy in AS and psoriatic arthritis is proved, respondents agreed that more studies will be needed to show efficacy for other SpA subsets.

Validation of a parent outcome questionnaire from pediatric cochlear implantation.  

PubMed

This paper analyzes the reliability and validity of a questionnaire designed by Archbold, Lutman, Gregory, O'Neil, and Nikolpoulos (2002) for the assessment of pediatric cochlear implantation. Parents of 61 youngsters (age range 5 to 16 years), who had the implant for at least 3 years, responded to the questionnaire and to an interview. The alpha reliability of the 11 questionnaire scales varied between .41 and .74. Content validity was assessed by comparison with parents' responses to an interview. In general, there was agreement between parents' concerns and views expressed in the interview and as assessed by the questionnaire. However, extra issues were identified in the interview, which suggest the need for increasing the breadth of the questionnaire. Criterion validity was assessed by identifying contrasting cases, with very low or very high scores in each scale, and analyzing the descriptions obtained in the interviews. For nine scales this analysis provided support for the validity of the questionnaire; two scales did not produce positive results. Correlations with interview scores were calculated for only four scales: two were positive and significant whereas two were not significant. A factor analysis of the questionnaire scales identified four components, interpreted as the child's functioning in social situations, attitudes to the process of implantation, support required in the long term, and effective use of the implant. Suggestions for further research and descriptive comments provided by parents are included. PMID:15932922

Item Response Theory Analysis of Two Questionnaire Measures of Arthritis-Related Self-Efficacy Beliefs from Community-Based US Samples  

PubMed Central

Using item response theory (IRT), we examined the Rheumatoid Arthritis Self-efficacy scale (RASE) collected from a People with Arthritis Can Exercise RCT (346 participants) and 2 subscales of the Arthritis Self-efficacy scale (ASE) collected from an Active Living Every Day (ALED) RCT (354 participants) to determine which one better identifies low arthritis self-efficacy in community-based adults with arthritis. The item parameters were estimated in Multilog using the graded response model. The 2 ASE subscales are adequately explained by one factor. There was evidence for 2 locally dependent item pairs; two items from these pairs were removed when we reran the model. The exploratory factor analysis results for RASE showed a multifactor solution which led to a 9-factor solution. In order to perform IRT analysis, one item from each of the 9 subfactors was selected. Both scales were effective at measuring a range of arthritis SE.

Initial results in prony analysis of power system response signals  

SciTech Connect

Prony analysis is an emerging methodology that extends Fourier analysis by directly estimating the frequency, damping, strength, and relative phase of modal components present in a given signal. The ability to extract such information from transient stability program simulations and from large-scale system tests or disturbances would be quite valuable to power system engineers. This paper reports early results in the application of this method to stability program output. It also includes benchmarks against known models and a brief mathematical summary.

Results of switching to milnacipran in fibromyalgia patients with an inadequate response to duloxetine: a phase IV pilot study  

PubMed Central

Background The purpose of this study was to evaluate the safety, tolerability, and efficacy of milnacipran following a direct switch from duloxetine in fibromyalgia patients experiencing inadequate clinical response to duloxetine after receiving treatment for 6 weeks or longer. Methods This exploratory study included 107 patients with fibromyalgia who had been treated with duloxetine 60 mg/day for at least 4 weeks prior to enrollment. Following a 2-week open-label period on duloxetine, patients who had visual analog scale pain scores ? 40 and were dissatisfied with current treatment were randomized 4:1 to milnacipran 100 mg/day (n = 86) or placebo (n = 21) for 10 weeks of double-blind treatment. The small placebo group was included solely to blind the study and minimize expectation bias among patients and investigators, and there was no preplanned statistical comparison between treatment groups. The primary efficacy parameter was the percentage of patients rating themselves as “much improved” or “very much improved” on the Patient Global Impression of Change (PGIC) at the final visit. Other efficacy parameters included changes in one-week recall visual analog scale pain, Fibromyalgia Impact Questionnaire Revised (FIQR), and Multiple Ability Self-Report Questionnaire (MASQ). Results Of patients switched to milnacipran, 32.9% were classified as PGIC responders, and they also demonstrated improvement in visual analog scale pain, FIQR total, and MASQ total scores (mean changes from baseline were ?12.3, ?7.77, and ?2.39, respectively). Nausea and dizziness were the most common treatment-emergent adverse events in patients switched to milnacipran, reported in 21% and 15%, respectively, of patients in this group. Conclusion Results from this exploratory study suggest that switching from duloxetine to milnacipran may be beneficial in some patients with fibromyalgia who have an inadequate response to duloxetine. Further research investigating the efficacy and safety of switching fibromyalgia therapies is warranted.

Evaluating a questionnaire to measure improvement initiatives in Swedish healthcare  

PubMed Central

Background Quality improvement initiatives have expanded recently within the healthcare sector. Studies have shown that less than 40% of these initiatives are successful, indicating the need for an instrument that can measure the progress and results of quality improvement initiatives and answer questions about how quality initiatives are conducted. The aim of the present study was to develop and test an instrument to measure improvement process and outcome in Swedish healthcare. Methods A questionnaire, founded on the Minnesota Innovation Survey (MIS), was developed in several steps. Items were merged and answer alternatives were revised. Employees participating in a county council improvement program received the web-based questionnaire. Data was analysed by descriptive statistics and correlation analysis. The questionnaire psychometric properties were investigated and an exploratory factor analysis was conducted. Results The Swedish Improvement Measurement Questionnaire consists of 27 items. The Improvement Effectiveness Outcome dimension consists of three items and has a Cronbach’s alpha coefficient of 0.67. The Internal Improvement Processes dimension consists of eight sub-dimensions with a total of 24 items. Cronbach’s alpha coefficient for the complete dimension was 0.72. Three significant item correlations were found. A large involvement in the improvement initiative was shown and the majority of the respondents were satisfied with their work. Conclusions The psychometric property tests suggest initial support for the questionnaire to study and evaluate quality improvement initiatives in Swedish healthcare settings. The overall satisfaction with the quality improvement initiative correlates positively to the awareness of individual responsibilities.

Coagulation response in dogs with and without systemic inflammatory response syndrome - preliminary results.  

PubMed

The impact of systemic inflammatory response syndrome (SIRS) on all phases of coagulation is largely unknown in dogs. Fifty-six healthy dogs (controls) and 25 diseased dogs were included. Based on physical and hematological examination, dogs were classified as "no-SIRS" (n=7) or "SIRS" (n=18). Evaluated coagulation variables included platelets, coagulation times, fibrinogen, antithrombin (AT), FVIII, protein C, protein S, activated protein C (APC)-ratio, calculated from aPTT with and without presence of APC, and kaolin-activated thrombelastography (TEG). Overall, no-SIRS and SIRS were characterized by hypocoaguable state (P<0.001 compared to controls) i.e., prolonged coagulation times, decreased AT (median 59 U/L and 89 U/L versus 126 U/L), and FVIII (median 19 U/L and 70 U/L versus 102 U/L). In no-SIRS and SIRS, APC-ratio was significantly lower than in the controls (median 1.1 and 2.0 versus 2.5, P<0.01, P<0.001). Severe coagulopathies may be present in critically ill dogs without concurrent SIRS. APC-resistance is a frequent finding in severely diseased dogs. PMID:22935745

Harm reduction measures and injecting inside prison versus mandatory drugs testing: results of a cross sectional anonymous questionnaire survey. The European Commission Network on HIV Infection and Hepatitis in Prison.

OBJECTIVES: (a) To determine both the frequency of injecting inside prison and use of sterilising tablets to clean needles in the previous four weeks; (b) to assess the efficiency of random mandatory drugs testing at detecting prisoners who inject heroin inside prison; (c) to determine the percentage of prisoners who had been offered vaccination against hepatitis B. DESIGN: Cross sectional willing anonymous salivary HIV surveillance linked to a self completion risk factor questionnaire. SETTING: Lowmoss prison, Glasgow, and Aberdeen prison on 11 and 30 October 1996. SUBJECTS: 293 (94%) of all 312 inmates at Lowmoss and 146 (93%) of all 157 at Aberdeen, resulting in 286 and 143 valid questionnaires. MAIN OUTCOME MEASURES: Frequency of injecting inside prison in the previous four weeks by injector inmates who had been in prison for at least four weeks. RESULTS: 116 (41%) Lowmoss and 53 (37%) Aberdeen prisoners had a history of injecting drug use but only 4% of inmates (17/395; 95% confidence interval 2% to 6%) had ever been offered vaccination against hepatitis B. 42 Lowmoss prisoners (estimated 207 injections and 258 uses of sterilising tablets) and 31 Aberdeen prisoners (229 injections, 221 uses) had injected inside prison in the previous four weeks. The prisons together held 112 injector inmates who had been in prison for more than four weeks, of whom 57 (51%; 42% to 60%) had injected in prison in the past four weeks; their estimated mean number of injections was 6.0 (SD 5.7). Prisoners injecting heroin six times in four weeks will test positive in random mandatory drugs testing on at most 18 days out of 28. CONCLUSIONS: Sterilising tablets and hepatitis B vaccination should be offered to all prisoners. Random mandatory drugs testing seriously underestimates injector inmates' harm reduction needs.

The Italian Version of the Glaucoma Symptom Scale Questionnaire: Translation, Validation, and Reliability.  

PubMed

PURPOSE:: To validate the Italian version of the Glaucoma Symptom Scale (GSS) Questionnaire and its symptoms and function subscales. METHODS:: This transversal validation study enrolled nonhospitalized patients with glaucoma, and a reference sample of patients without eye diseases. Eligible participants had to be cognitively able to respond to a health status interview. The Italian self-administered versions of the 25-item National Eye Institute-Visual Function Questionnaire and the GSS Questionnaire were administered to all participants. Reliability and validity of the Italian translation of the GSS Questionnaire were tested using standard statistical methods for questionnaire validation. RESULTS:: Ninety-seven patients were enrolled. Cronbach ? coefficient ranged from 0.72 to 0.92 across subscales and eyes. Test-retest stability was >85% for each subscale and eye. The control group of participants had better scale scores across all dimensions of vision-targeted health-related quality of life captured by the GSS Questionnaire (P<0.05) and there were good correlations between responses GSS Questionnaire subscales and analogous domains of the 25-item National Eye Institute-Visual Function Questionnaire. CONCLUSIONS:: The Italian version of the GSS Questionnaire has good validity, discriminatory power, internal consistence and reliability, showing psychometric properties comparable with those of the English version, and can therefore be used in clinical research as a specific measure of vision-related quality of life in Italian-speaking patients with ocular hypertension or glaucoma.

The Toronto Empathy Questionnaire  

PubMed Central

In order to formulate a parsimonious tool to assess empathy, we used factor analysis on a combination of self-report measures to examine consensus and developed a brief self-report measure of this common factor. The Toronto Empathy Questionnaire (TEQ) represents empathy as a primarily emotional process. In three studies, the TEQ demonstrated strong convergent validity, correlating positively with behavioral measures of social decoding, self-report measures of empathy, and negatively with a measure of Autism symptomatology. Moreover, it exhibited good internal consistency and high test-retest reliability. The TEQ is a brief, reliable, and valid instrument for the assessment of empathy.

The Pediatric Stroke Recurrence and Recovery Questionnaire  

PubMed Central

Objective: We developed the Recurrence and Recovery Questionnaire (RRQ) by converting the Pediatric Stroke Outcome Measure (PSOM) to a questionnaire for telephone interview and sought to validate the RRQ in a large cohort. Method: We analyzed parents' RRQ responses and same-day PSOM assessments for 232 children who had arterial ischemic stroke, cerebral sinovenous thrombosis, or presumed perinatal ischemic stroke. We assessed the agreement and consistency of the PSOM and RRQ, and we identified conditions that contributed to differences between the 2 measures. We tested selected factors as predictors of differences between the total PSOM and total RRQ (tPSOM and tRRQ) scores. Results: Median PSOM score was 1.5 and median RRQ score was 1.5. There was good agreement between tPSOM and tRRQ, and RRQ was a reliable estimator of PSOM at the total and component level. Preexisting neurologic deficits or chronic illnesses increased the difference between the tPSOM and tRRQ; the chronic illness effect was confirmed with univariate analysis. Conclusions: The RRQ can characterize poststroke function when a child cannot return for examination. While the RRQ is not identical to the PSOM, the 2 measures likely assess closely related aspects of recovery. The RRQ is particularly useful when assessing outcomes of large cohorts, and will be useful in performing long-term follow-up studies of pediatric stroke.

Household Responses to School Closure Resulting from Outbreak of Influenza B, North Carolina  

PubMed Central

School closure is a proposed strategy for reducing influenza transmission during a pandemic. Few studies have assessed how families respond to closures, or whether other interactions during closure could reduce this strategy’s effect. Questionnaires were administered to 220 households (438 adults and 355 children) with school-age children in a North Carolina county during an influenza B virus outbreak that resulted in school closure. Closure was considered appropriate by 201 (91%) households. No adults missed work to solely provide childcare, and only 22 (10%) households required special childcare arrangements; 2 households incurred additional costs. Eighty-nine percent of children visited at least 1 public location during the closure despite county recommendations to avoid large gatherings. Although behavior and attitudes might differ during a pandemic, these results suggest short-term closure did not cause substantial hardship for parents. Pandemic planning guidance should address the potential for transmission in public areas during school closure.

The impact of response to the results of diagnostic tests for malaria: cost-benefit analysis  

PubMed Central

Objective Rapid diagnostic tests for malaria seem cost effective in standard analyses, but these do not take account of clinicians’ response to test results. This study tested the impact of clinicians’ response to rapid diagnostic test or microscopy results on the costs and benefits of testing at different levels of malaria transmission and in different age groups. Design Cost-benefit analysis using a decision tree model and clinical data on the effectiveness of diagnostic tests for malaria, their costs, and clinicians’ response to test results. Setting Tanzania. Methods Data were obtained from a clinical trial of 2425 patients carried out in three settings of varying transmission. Results At moderate and low levels of malaria transmission, rapid diagnostic tests were more cost beneficial than microscopy, and both more so than presumptive treatment, but only where response was consistent with test results. At the levels of prescription of antimalarial drugs to patients with negative tests that have been found in observational studies and trials, neither test methodis likely to be cost beneficial, incurring costs 10-250% higher, depending on transmission rate, than would have been the case with fully consistent responses to all test results. Microscopy becomes more cost beneficial than rapid diagnostic tests when its sensitivity under operational conditions approaches that of rapid diagnostic tests. Conclusions Improving diagnostic methods, including rapid diagnostic tests, can reduce costs and enhance the benefits of effective antimalarial drugs, but only if the consistency of response to test results is also improved. Investing in methods to improve rational response to tests is essential. Economic evaluations of diagnostic tests should take into account whether clinicians’ response is consistent with test results.

A parent completed questionnaire to describe the patterns of wheezing and other respiratory symptoms in infants and preschool children  

PubMed Central

Aim: To develop a standardised and validated respiratory symptom questionnaire for use in epidemiological or follow up studies in infants and preschool children. Methodology: After initial design and development, the questionnaire was administered to two cohorts of subjects, one recruited from a respiratory clinic and the other from a postnatal ward. The two cohorts then repeated the questionnaire, two weeks apart. The qualities of the questionnaire were assessed. Results: Response rate to the initial questionnaire was 100% for the clinic based cohort and 64% for postnatally recruited families (total number of subjects 114). Questions showed good to moderate short term reliability (weighted kappa scores 0.47–0.7; average correct classification rates 0.74–0.91). Four domain concept scores showed excellent internal consistency (Cronbach alpha scores 0.87–0.95). Using principal component factor analysis, four new domains were devised showing acceptable construct validity and internal consistency. Criterion validity was assessed using a respiratory physician based diagnosis of asthma (RPBDA) as the gold standard for comparison. All eight scales in the questionnaire could significantly distinguish between infants with RPBDA and well or mildly symptomatic subjects. Conclusion: We have developed a practical, acceptable questionnaire with eight concept domains for use in infants and preschool children. The questionnaire has strong construct validity and internal consistency with good short term reliability of questions. More detailed study of criterion validity and the responsiveness of the questionnaire is required using a larger population and including children with the different phenotypes of wheezy illness.

Importance of questionnaire context for a physical activity question.  

PubMed

Adequate information about physical activity habits is essential for surveillance, implementing, and evaluating public health initiatives in this area. Previous studies have shown that question order and differences in wording result in systematic differences in people's responses to questionnaires; however, this has never been shown for physical activity questions. The aim was to study the influence of different formulations and question order on self-report physical activity in a population-based health interview survey. Four samples of each 1000 adults were drawn at random from the National Person Register. A new question about physical activity was included with minor differences in formulations in samples 1-3. Furthermore, the question in sample 2 was included in sample 4 but was placed in the end of the questionnaire. The mean time spent on moderate physical activity varied between the four samples from 57 to 100?min/day. Question order was associated with the reported number of minutes spent on moderate-intensity physical activity and with prevalence of meeting the recommendation, whereas physical inactivity was associated with the differences in formulation of the question. Questionnaire context influences the way people respond to questions about physical activity significantly and should be tested systematically in validation studies of physical activity questionnaires.

When parents disclose BRCA1/2 test results: Their communication and perceptions of offspring response  

PubMed Central

Background BRCA1/2 testing is not recommended for children, as risk reduction measures and screening are not generally recommended before 25 years old (YO). Little is known about the prevalence and predictors of parent communication to offspring and how offspring respond to this communication. Methods Semi-structured interviews were conducted with parents who had BRCA1/2 testing and at least one child <25 YO. Logistic regressions were utilized to evaluate associations with communication. Framework analysis was utilized to analyze open-ended responses. Results 253 parents completed interviews (61% response rate), reporting on 505 offspring. 29% of parents were BRCA1/2 mutation carriers. 334 (66%) offspring learned of their parent’s test result. Older offspring age (p<=0.01), offspring gender (female, p=0.05), parents’ negative test result (p=0.03) and parents’ education (high-school only, p=0.02) were associated with communication to offspring. The most frequently reported initial offspring responses were neutral (41%) or relief (28%). 13% of offspring were reported to experience concern or distress (11%) in response to parental communication of their test results. Distress was more frequently perceived among offspring learning of their parent’s BRCA1/2 positive or variant of uncertain significance result. Conclusion Many parents communicate their BRCA1/2 test results to young offspring. Parents’ perceptions of offspring responses appear to vary by offspring age and parent test result. A better understanding of how young offspring respond to information about hereditary risk for adult cancer could provide opportunities to optimize adaptive psychosocial responses to risk information and performance of health behaviors, in adolescence and throughout an at-risk lifespan.

Development and validation of the Fat Talk Questionnaire.  

PubMed

Fat talk refers to negative body-related conversations between girls or young women. This research aimed to use qualitative data from young women to guide development of a quantitative fat talk measure. In Study 1, a preliminary 62-item questionnaire was developed and administered to 200 female participants. Item analysis resulted in the elimination of items, yielding a final questionnaire with 14 items. Principal components analysis of this questionnaire indicated a single factor. In Study 2, 95 female participants completed the newly developed Fat Talk Questionnaire and theoretically related (e.g., body image) and unrelated (e.g., social desirability) constructs. Additionally, 49 male participants completed the questionnaire to examine known groups validity. In Study 3, 54 participants completed the Fat Talk Questionnaire on two occasions to assess temporal stability. The results showed that the Fat Talk Questionnaire is reliable and valid. The Fat Talk Questionnaire may have important utility in future research. PMID:23201392

Physical Activity Questionnaire Comprehension-Lessons from Cognitive Interviews  

PubMed Central

Purpose To determine if respondents share researchers’ understandings of concepts and questions frequently used in the assessment of usual physical activity behavior. Methods As part of On the Move, a study aimed at reducing measurement error in self-reported physical activity (PA), we conducted cognitive interviews with 19 men and 21 women, ages 45-65, regarding their responses to the PA questionnaires used in two large, population-based studies, LACE (Life After Cancer Epidemiology) and CMH (California Men’s Health Study). One questionnaire asks about the frequency, duration, and perceived intensity of a range of specific activities in several different domains over the past 12 months. The second questionnaire asks about frequency and duration of specific, mostly recreational activities, grouped by intensity (i.e., moderate or vigorous) over the past 3 months. We used verbal probing techniques to allow respondents to describe their thought processes as they completed the questionnaires. All interviews were tape-recorded and transcribed, and the transcripts were then analyzed using standard qualitative methods. Results Cognitive interviews demonstrated that a sizable number of respondents understood “intensity” in terms of emotional or psychological intensity, rather than physical effort. As a result, the perceived intensity with which a participant reported doing a specific activity often bore little relationship to the MET value of that activity. Additionally, participants often counted the same activity more than once, overestimated work-related PA, and understood activities that were grouped together in a single category to be definitive lists rather than examples. Conclusion Cognitive interviews revealed significant gaps between respondents’ interpretations of some physical activity questions and researchers’ assumptions about what those questions were intended to measure. Some sources of measurement error in self-reported PA may be minimized by additional research that focuses on the cognitive processes required to respond to PA questionnaires.

Results of an emergency response atmospheric dispersion model comparison using a state accepted statistical protocol  

SciTech Connect

The Rocky Flats Plant, located approximately 26 km northwest of downtown Denver, Colorado, has developed an emergency response atmospheric dispersion model for complex terrain applications. Plant personnel would use the model, known as the Terrain-Responsive Atmospheric Code (TRAC) (Hodgin 1985) to project plume impacts and provide off-site protective action recommendations to the State of Colorado should a hazardous material release occur from the facility. The Colorado Department of Health (CDH) entered into an interagency agreement with the Rocky Flats Plant prime contractor, EG&G Rocky Flats, and the US Department of Energy to evaluate TRAC as an acceptable emergency response tool. After exhaustive research of similar evaluation processes from other emergency response and regulatory organizations, the interagency committee devised a formal acceptance process. The process contains an evaluation protocol (Hodgin and Smith 1992), descriptions of responsibilities, an identified experimental data set to use in the evaluation, and judgment criteria for model acceptance. The evaluation protocol is general enough to allow for different implementations. This paper explains one implementation, shows protocol results for a test case, and presents results of a comparison between versions of TRAC with different wind Field codes: a two dimensional mass consistent code called WINDS (Fosberg et al. 1976) that has been extended to three dimensions, and a fully 3 dimensional mass conserving code called NUATMOS (Ross and Smith 1987, Ross et al. 1988).

The 2010 nephrology quiz and questionnaire: part 1.  

PubMed

Presentation of the Nephrology Quiz and Questionnaire (NQQ) has become an annual "tradition" at the meetings of the American Society of Nephrology. It is a very popular session judged by consistently large attendance. Members of the audience test their knowledge and judgment on a series of case-oriented questions prepared and discussed by experts. They can also compare their answers in real time, using audience response devices, to those of program directors of nephrology training programs in the United States, acquired through an Internet-based questionnaire. As in the past, the topics covered were transplantation, fluid and electrolyte disorders, end-stage renal disease and dialysis, and glomerular disorders. Two challenging cases representing each of these categories along with single best answer questions were prepared by a panel of experts (Drs. Hricik, Palmer, Bargman, and Fervenza, respectively). The "correct" and "incorrect" answers then were briefly discussed, after the audience responses and the results of the questionnaire were displayed. The 2010 version of the NQQ was exceptionally challenging, and the audience, for the first time, gained a better overall correct answer score than the program directors, but the margin was small. In this issue we present the transplantation and fluid and electrolyte cases; the remaining end-stage renal disease and dialysis, and glomerular disorder cases will be presented next month. These articles try to recapitulate the session and reproduce its educational value for a larger audience--the readers of the Clinical Journal of the American Society of Nephrology. Have fun.

Advanced commercial survey methods (COMSURV). Volume 1. Demonstration of tailored versus general questionnaires. Final report  

SciTech Connect

This report discusses the results of a demonstration to assess the effects of questionnaire design on response rates, data quality, and general questionnaire performance in commercial sector surveys. With the cooperation of the Virginia Power Company (VEPCO), the concept of tailoring the questionnaire to specific types of commercial establishments was tested in a survey of food stores and office buildings. Tailoring involves the use of trade-specific language, questions about specialized equipment, and special instructions. One result of this study was the demonstration that it is possible to collect detailed trade-specific information with a tailored mail survey instrument. It was also expected that tailoring would improve both overall response rates and question-specific response rates, but this does not appear to be the case. In fact, the results indicate that tailored questionnaires may decrease overall response rates since misclassified units are less likely to respond. In view of this, some guidelines for the use of tailored survey instruments are presented. This report also contains numerous comparisons of the VEPCO survey results with results from the Nonresidential Building Energy Consumption Survey (NBECS). The comparisons reveal that the mail survey technique did provide estimates which compared reasonably with larger-scale on-site surveys.

Genetic complementation results in augmented autoantibody responses to lupus-associated antigens.  

PubMed

Lupus-prone female New Zealand Mixed (NZM)2328 mice develop high titers of anti-nuclear and anti-dsDNA autoantibodies. Despite high expression of type I IFNs, these mice do not develop autoantibodies to the small nuclear ribonucleoprotein (snRNP) complex. Thus, additional genetic factors must regulate the generation of anti-snRNP autoantibodies. In contrast, despite much lower expression of type 1 IFNs, the diabetes-prone NOD mice spontaneously make anti-snRNP autoantibodies, albeit at a low incidence. To determine whether combination of high type I IFN response of NZM mice with appropriate susceptibility genes of NOD mice would result in anti-snRNP Ab response, cohorts of (NZM2328 x NOD)F(1) mice were generated and characterized for development of autoimmunity. In comparison with parental strains, the PBMCs from F(1) mice showed intermediate expression of type I IFN-responsive genes and augmented expression of IL-6 transcripts. TLR7 expression was similar in all strains. The F(1) mice had very high incidence and titer of anti-snRNP autoantibodies, anti-nuclear Abs, and anti-dsDNA autoantibodies. The levels of anti-snRNP autoantibody correlated with the expression levels of type I IFN-responsive genes. None of the F(1) mice developed diabetes, and only female mice developed severe renal disease. Our data demonstrate that only in presence of appropriate susceptibility genes, anti-snRNP autoantibodies are induced and type I IFNs amplify this response. A synergy between IL-6 and type I IFNs might be critical for amplifying overall autoantibody responses in systemic lupus erythematosus. In NZM/NOD F(1) mouse, genetic complementation between NZM and NOD genes leads to expression of phenotypes similar to those seen in certain lupus patients. PMID:19667095

Development of a new high altitude electromagnetic pulse (HEMP) environment and resulting over head line responses  

SciTech Connect

Being able to accurately determine the response of an electrical system which is excited by a high altitude nuclear electromagnetic pulse (EMP) requires a knowledge of the time history of the incident EMP field strength, as well as its angle of incidence and polarization. A commonly used, unclassified, description of this environment is provided by the ''Bell Laboratory waveform.'' Recent studies have shown, however, that this EMP waveform tends to overestimate the response of an above-ground transmission line by more than an order of magnitude. As a result, other unclassified high altitude EMP environments have been developed. This presentation discusses the development of two alternate unclassified EMP environment descriptions: one arising from a simple radiating dipole moment model, and the other resulting from curve-fitting the calculated fields from a computer code named CHAP. For both of these EMP models, the electric field at two earth observation points are compared. These fields are then coupled to an above-ground line and the resulting open-circuit voltage responses are compared. Using the CHAP EMP environment, a limited parametric study of the peak positive and negative open-circuit voltage is then performed and surface plots of these peak voltages are presented. 8 refs., 21 figs., 1 tab.

Chronic right ventricular pressure overload results in a hyperplastic rather than a hypertrophic myocardial response  

PubMed Central

Myocardial hyperplasia is generally considered to occur only during fetal development. However, recent evidence suggests that this type of response may also be triggered by cardiac overload after birth. In congenital heart disease, loading conditions are frequently abnormal, thereby affecting ventricular function. We hypothesized that chronic right ventricular pressure overload imposed on neonatal hearts initiates a hyperplastic response in the right ventricular myocardium. To test this, young lambs (aged 2–3 weeks) underwent adjustable pulmonary artery banding to obtain peak right ventricular pressures equal to left ventricular pressures for 8 weeks. Transmural cardiac tissue samples from the right and left ventricles of five banded and five age-matched control animals were studied. We found that chronic right ventricular pressure overload resulted in a twofold increase in right-to-left ventricle wall thickness ratio. Morphometric right ventricular myocardial tissue analysis revealed no changes in tissue composition between the two groups; nor were right ventricular myocyte dimensions, relative number of binucleated myocytes, or myocardial DNA concentration significantly different from control values. In chronic pressure overloaded right ventricular myocardium, significantly (P < 0.01) more myocyte nuclei were positive for the proliferation marker proliferating cellular nuclear antigen than in control right ventricular myocardium. Chronic right ventricular pressure overload applied in neonatal sheep hearts results in a significant increase in right ventricular free wall thickness which is primarily the result of a hyperplastic myocardial response.

Results from two research projects concerning aversion responses including the blink reflex  

NASA Astrophysics Data System (ADS)

In order to examine the safety philosophy for laser classes 2 and 2M according to the international laser standard IEC 60825-1, which is based on the existence of aversion responses including the blink reflex, two research projects have been funded by the Federal Institute of Occupational Safety and Health (FIOSH) in Germany. In total, 2,250 volunteers have been investigated in the blink-reflex study in various test situations, where a collimated beam, a divergent beam, a scanned laser line or LED irradiation have been used as a bright optical stimulus. The various test situations included, for example, a free laser beam (like that used in the case of laser adjustment), an eye-tracking system, in which visual tasks have been performed, or LEDs used as single elements or in a cluster. 796 volunteers took part in the aversion response study. Concerning the blink reflex, the mean value of the frequency has been estimated to be 18.36 % within a range extending from 13.8 % up to 36.1 % depending on various parameters and applied optical sources. Their respective influences will be explained. Aversion responses, like head and eye movements, have been found to be relatively seldom events, since only 4.65 % of volunteers showed a reaction which belonged to this category of inherent, physiological, protection reactions. The different parameters which are mainly responsible for the respective results concerning the blink reflex and aversion responses will be dealt with and explained, as they have been experimentally achieved up to now.

Web-Based Versus Traditional Paper Questionnaires: A Mixed-Mode Survey With a Nordic Perspective  

PubMed Central

Background Survey response rates have been declining over the past decade. The more widespread use of the Internet and Web-based technologies among potential health survey participants suggests that Web-based questionnaires may be an alternative to paper questionnaires in future epidemiological studies. Objective To compare response rates in a population of parents by using 4 different modes of data collection for a questionnaire survey of which 1 involved a nonmonetary incentive. Methods A random sample of 3148 parents of Danish children aged 2-17 years were invited to participate in the Danish part of the NordChild 2011 survey on their children’s health and welfare. NordChild was conducted in 1984 and 1996 in collaboration with Finland, Iceland, Norway, and Sweden using mailed paper questionnaires only. In 2011, all countries used conventional paper versions only except Denmark where the parents were randomized into 4 groups: (1) 789 received a paper questionnaire only (paper), (2) 786 received the paper questionnaire and a log-in code to the Web-based questionnaire (paper/Web), (3) 787 received a log-in code to the Web-based questionnaire (Web), and (4) 786 received log-in details to the Web-based questionnaire and were given an incentive consisting of a chance to win a tablet computer (Web/tablet). In connection with the first reminder, the nonresponders in the paper, paper/Web, and Web groups were also present with the opportunity to win a tablet computer as a means of motivation. Descriptive analysis was performed using chi-square tests. Odds ratios were used to estimate differences in response rates between the 4 modes. Results In 2011, 1704 of 3148 (54.13%) respondents answered the Danish questionnaire. The highest response rate was with the paper mode (n=443, 56.2%). The other groups had similar response rates: paper/Web (n=422, 53.7%), Web (n=420, 53.4%), and Web/tablet (n=419, 53.3%) modes. Compared to the paper mode, the odds for response rate in the paper/Web decreased by 9% (OR 0.91, 95% CI 0.74-1.10) and by 11% (OR 0.89, 95% CI 0.73-1.09) in the Web and Web/tablet modes. The total number of responders for NordChild declined from 10,291 of 15,339 (67.09%) in 1984 and 10,667 of 15,254 (69.93%) in 1996 to 7805 of 15,945 (48.95%) in 2011 with similar declines in all 5 Nordic countries. Conclusions Web-based questionnaires could replace traditional paper questionnaires with minor effects on response rates and lower costs. The increasing effect on the response rate on participants replying for a nonmonetary incentive could only be estimated within the 2 Web-based questionnaire modes before the first reminder. Alternative platforms to reach higher participation rates in population surveys should reflect the development of electronic devices and the ways in which the population primarily accesses the Internet.

Defensive practice among psychiatrists: a questionnaire survey  

PubMed Central

Objective: There has been little research on the prevalence of defensive practice within hospital settings. The aim of this report was to examine the extent of defensiveness among psychiatrists and to examine the relationship between defensiveness and seniority, as well as the effect of previous experiences on the level of defensiveness. Design: A postal questionnaire survey on defensive practice. Setting: Northern Region of England. Subjects: 154 psychiatrists in the region. Results: 96 responses were received from 48 equivalent consultants, 18 specialist registrars, and 23 equivalent senior house officers. Overall, 75% of those who replied had taken defensive actions within the past month. In particular, 21% had admitted patients overcautiously and 29% had placed patients on higher levels of observations. Junior psychiatrists were particularly prone to practise defensively. Important contributing factors included previous experience of complaints (against colleague or self), critical incidents, and legal claims. Conclusion: Almost three quarters of the psychiatrists who responded had practised defensively within the past month. The higher propensity of junior trainees to practise defensively may be attributable to their lack of confidence and experience. Experience of complaints (colleague or self) and critical incidents were important factors for defensive practice. Better and more structured training might reduce the high level of defensive practice and the way complaints and investigations are handled should be improved to maintain a truly "no blame" environment conducive to learning from past experience.

Fundamental issues in questionnaire design.  

PubMed

The questionnaire is probably the most common form of data collection tool used in nursing research. There is a misconception that anyone with a clear grasp of English and a modicum of common sense can design an effective questionnaire. Contrary to such common belief, this article will demonstrate that questionnaire design is a complex and time consuming process, but a necessary labour to ensure valid and reliable data is collected. In addition, meticulous construction is more likely to yield data that can be utilized in the pursuit of objective, quantitative and generalizable truths, upon which practice and policy decisions can be formulated. This article examines a myriad of fundamental issues surrounding questionnaire design, which encompass question wording, question order, presentation, administration and data collection, amongst other issues.

The MPC&A Questionnaire  

SciTech Connect

The questionnaire is the instrument used for recording performance data on the nuclear material protection, control, and accountability (MPC&A) system at a nuclear facility. The performance information provides a basis for evaluating the effectiveness of the MPC&A system. The goal for the questionnaire is to provide an accurate representation of the performance of the MPC&A system as it currently exists in the facility. Performance grades for all basic MPC&A functions should realistically reflect the actual level of performance at the time the survey is conducted. The questionnaire was developed after testing and benchmarking the material control and accountability (MC&A) system effectiveness tool (MSET) in the United States. The benchmarking exercise at the Idaho National Laboratory (INL) proved extremely valuable for improving the content and quality of the early versions of the questionnaire. Members of the INL benchmark team identified many areas of the questionnaire where questions should be clarified and areas where additional questions should be incorporated. The questionnaire addresses all elements of the MC&A system. Specific parts pertain to the foundation for the facility's overall MPC&A system, and other parts pertain to the specific functions of the operational MPC&A system. The questionnaire includes performance metrics for each of the basic functions or tasks performed in the operational MPC&A system. All of those basic functions or tasks are represented as basic events in the MPC&A fault tree. Performance metrics are to be used during completion of the questionnaire to report what is actually being done in relation to what should be done in the performance of MPC&A functions.

Summary and results of the joint WMD-DAC/Alameda County bioterrorism response plan exercise.  

SciTech Connect

On June 12,2003, the Alameda County Public Health Department and Sandia National Laboratories/CA jointly conducted an exercise that used a Weapons of Mass Destruction-Decision Analysis Center (WMD-DAC) bioterrorism attack simulation to test the effectiveness of the county's emergency response plan. The exercise was driven by an assumed release (in the vicinity of the Berkeley Marina), and subsequent spread, of a small quantity of aerosolized, weapons-grade anthrax spores. The simulation used several key WMD-DAC capabilities, namely: (1) integration with an atmospheric dispersion model to calculate expected dose levels in the affected areas, (2) a individual-tracking capability for both infected and non-infected persons as they made decisions, sought treatment, and received prophylaxis drugs, and (3) a user interface that allows exercise participants to affect the scenario evolution and outcome. The analysis of the county's response plan included documenting and reviewing the decisions made by participants during the exercise. Twenty-six local and regional officials representing the health care system, emergency medical services and law enforcement were involved in responding to the simulated attack. The results of this joint effort include lessons learned both by the Alameda County officials regarding implementation of their bioterrorism response plan and by the Sandia representatives about conducting exercises of this type. These observations are reviewed in this report, and they form a basis for providing a better understanding of group/individual decision processes and for identifying effective communication options among decision makers.

Closed Head Injury in a Mouse Model Results in Molecular Changes Indicating Inflammatory Responses  

PubMed Central

Abstract Cerebral gene expression changes in response to traumatic brain injury will provide useful information in the search for future trauma treatment. In order to characterize the outcome of mild brain injury, we studied C57BL/6J mice in a weight-drop, closed head injury model. At various times post-injury, mRNA was isolated from neocortex and hippocampus and transcriptional alterations were studied using quantitative reverse transcriptase PCR and gene array analysis. At three days post-injury, the results showed unilateral injury responses, both in neocortex and hippocampus, with the main effect seen on the side of the skull hit by the dropping weight. Upregulated transcripts encoded products characterizing reactive astrocytes, phagocytes, microglia, and immune-reactive cells. Markers for oligodendrocytes and T-cells were not altered. Notably, strong differences in the responses among individual mice were seen (e.g., for the Gfap transcript expressed by reactive astrocytes and the chemokine Ccl3 transcript expressed by activated microglial cells). In conclusion, mild TBI chiefly activates transcripts leading to tissue signaling, inflammatory processes, and chemokine signaling, as in focal brain injury, suggesting putative targets for drug development.

Modeling and experimental results of CdxZn1-xTe detector response  

NASA Astrophysics Data System (ADS)

We have developed a model of the statistical variations in the electrical charge transport in CdxZn1-xTe(CZT) detectors. The model includes a simulation of the charge carrier generation for each photon interaction, using a calculated absorption coefficient of the photoelectric absorption. Next, we simulate the induced signal as carriers drift towards the collecting electrode under trapping conditions with negligible detrapping. Finally, a pulse height histogram is composed simulating the spectral response of the detector and incorporating the electronic noise component. A comparison between experimental and calculated CZT spectra was performed. These results and the potential for using the model in detector design will be discussed and presented.

Interim PET response criteria in paediatric non-Hodgkin's lymphoma. Results from a retrospective multicenter reading.  

PubMed

Aim: To evaluate the use and reliability of the PET-based response criteria for interim PET (iPET) in terms of interobserver variability in pediatric and adolescent patients suffering from non-Hodgkin´s lymphoma (NHL). Particular attention was given to the identification of visual cutoff to separate patients with a favourable outcome. Patients, methods: Retrospective analysis of PET-datasets of 18 children and adolescents suffering from NHL who underwent iPET after two cycles of chemotherapy for response assessment. Datasets were evaluated and rated in three independent review centers (RC) (blinded-read, intra-center consensus) using a visual 5-point response scale. Ratings were compared to clinical outcome. Pairwise interobserver agreement was analysed with Cohen's kappa-test (?). Overall agreement (between attended RCs) was assessed with Fleiss' ?-test. Results: Four patients suffered relapse (early, n = 2; late, n = 2). Per region analyses on interobserver variability revealed a "substantial" agreement (Fleiss' ??=?0.618). Per patient analyses revealed concordant iPET-ratings in eight patients: iPET-negative (iPET-), n = 5; iPET-positive (iPET+), n = 2; iPET-inconclusive (iPET±), n = 1. Discordant ratings were found in the remaining patients. Patients with early relapse were concordantly identified using mediastinal blood pool structures (MBPS, score ??3) as visual cutoff between iPET+ or iPET-, respectively. However, patients with late relapse were not concordantly identified taking the MBPS as visual cutoff. Conclusion: The iPET interpretation using a dedicated PET-based response scale assured a low interobserver variability in per-region but not in per-patient analyses in a multicenter read. Using a sensitive read out (iPET+, score ??3) a reliable identification of patients suffering relapse was limited to those with early relapse. PMID:23928982

Responses of Tundra Ecosystems to Environmental Change: Observational and Experimental Results  

NASA Astrophysics Data System (ADS)

Evidence of environmental changes due to human-enhanced climate warming continues to accumulate from polar regions. Responses in tundra and taiga ecosystems to climate changes have been variable because of the wide range in process response rates, from metabolic processes to adjustments in ecosystem carbon balance, and the variability in environmental settings across local to regional scales. For example, strong increases in rates of plant growth and changes in species composition and abundance have been observed in parts of the Low Arctic, but very little change has been measured in high arctic tundra. A dramatic increase in the cover of deciduous shrubs in areas of the western North American Arctic is predicted to result in positive feedbacks to soil temperature, through increased surface roughness and snow depth, and to atmospheric heating by reducing albedo. Increased shrub cover has also been found in long-term experimental warming studies conducted throughout the tundra biome as part of the International Tundra Experiment (ITEX). Warming is also affecting the carbon balance of tundra and taiga, which hold 25% of the soil carbon of global terrestrial ecosystems. However, trajectories of these changes are largely unknown for most northern systems, and differ because of initial conditions of the carbon and nutrient economy. Over the longer-term, the positive increases in plant growth may be constrained by negative feedbacks to nutrient cycling, as increases in C:N ratios of plant litter slow the release of nitrogen to soils. However, nitrogen availability has been shown to increase in response to short-term warming. In this presentation, I will review the responses of tundra ecosystems to climate variability and change, both through observational and experimental studies.

Identical Excimer Laser PTK Treatments in Rabbits Result in Two Distinct Haze Responses  

PubMed Central

Purpose. To obtain objective light-scattering measurements to test a hypothesis that identical PTK treatments cause distinct low- and high-level light-scattering responses in rabbit corneas. Methods. An excimer laser was used to produce identical 6-mm diameter phototherapeutic keratectomy treatments (PTK) in 32 pigmented rabbits. Eyes were treated by performing a 40-?m epithelial ablation, followed by a 100-?m stromal PTK. Objective scattering measurements were made before treatment, weekly up to 5 weeks, and then biweekly to 9 weeks. Confocal microscopy was performed on several corneas at 4 and 7 weeks. Results. Mean scattering levels split into distinct low- and high-scattering groups 2 weeks after treatment and remained distinct until week 7 (P < 0.003). Scattering in the low group reached a broad peak that lasted from weeks 2 to 4 at approximately 3 times the pretreatment level. Scattering in the high group peaked at 3 weeks at approximately 12 times the pretreatment level. Scattering levels diminished after reaching their peaks. Confocal images showed a band of highly reflective material in the anterior stroma that extended much deeper in corneas from the high group. The reflective band in the highly scattering corneas obscured the posterior stroma from view for up to 5 weeks. Conclusions. Quantitative scattering data obtained with the scatterometer suggest that identical PTK treatments indeed result in distinct low- and high-level light-scattering responses in rabbits.

Climate Responses to Stratospheric SRM: Results from a Perturbed Physics Ensemble Modeling Experiment  

NASA Astrophysics Data System (ADS)

While many have argued that the potential future deployment of solar radiation management (SRM) technologies hinges upon the uncertainty around the value of climate sensitivity, modeling studies of the climate’s response to SRM forcings have thus far focused on best-guess modeling frameworks which yield climate sensitivity values close to the Coupled Model Intercomparison Project (CMIP) dataset mean. Thus, most SRM modeling experiments to-date say little about the range of climate responses we may observe if SRM were implemented in high- or low- climate sensitivity worlds. The work presented here aims to see how climate responses to SRM under the physics that produce high climate sensitivity may differ from the responses modeled so far using best-guess model parameters. We present preliminary results from a “perturbed physics” ensemble modeling experiment implemented using climateprediction.net (cpdn). Perturbed physics climate modeling experiments simulate past and future climate scenarios using a wide combination of model parameter combinations with the aim of both simulating past climate with some level of accuracy and also projecting future climates that exhibit a wide range of climate sensitivities. Ensemble members were selected using an algorithm for model selection regional surface temperature data from the cpdn simulation output for model years 1961-2005 (in five year averages) to observational data from the HadCRUT3 (land) and HadSST2 (ocean) datasets at the same spatial and temporal resolution. Stratospheric SRM is simulated in the model by specifying stratospheric optical depth. Several scenarios are tested including several designed to stabilize mean global temperature at different levels, two scenarios designed to rapidly cool the climate starting in 2020 and 2035, respectively, and a scenario which makes small, periodic perturbations (in order to glean information about detectability and the feasibility of large-scale SRM testing schemes). All scenarios use anthropogenic emissions scenario RCP 4.5 and are compared to an RCP 4.5/no-SRM control. We will present global and regional results from this ongoing experiment.

The effect of ambient pressure on well chamber response: experimental results with empirical correction factors.  

PubMed

For some air-communicating well-type chambers used for low-energy brachytherapy source assay, deviations from expected values of measured air kerma strength were observed at low pressures associated with high altitudes. This effect is consistent with an overcompensation by the air density correction to standard atmospheric temperature and pressure (P(TP)). This work demonstrates that the P(TP) correction does not fully compensate for the high altitude pressure effects that are seen with air-communicating chambers at low photon energies in the range of 20-100 keV. Deviations of up to 18% at a pressure corresponding to an approximate elevation of 8500 ft for photon energies of 20 keV are possible. For high-energy photons and for high-energy beta emitters in air-communicating chambers the P(TP) factor is applicable. As expected, the ambient pressure does not significantly affect the response of pressurized well chambers (within 1%) to either low- or high-energy photons. However, when used with beta emitters, pressurized chambers appear to exhibit a slight dependence on the ambient pressure. Using measured data, the response and correction factors were determined for three models of air-communicating well chambers for low-energy photon sources at various pressures corresponding to elevations above sea level. Monte Carlo calculations were also performed which were correlated with the experimental findings. A more complete study of the Monte Carlo calculations is presented in the accompanying paper, "The effect of ambient pressure on well chamber response: Monte Carlo calculated results for the HDR1000 Plus."

Intralesional injections of alefacept may predict systemic response to intramuscular alefacept: results from a pilot study.  

PubMed

Background: Alefacept (Amevive®) was the first biologic agent to be approved by the FDA for use in moderate to severe chronic plaque psoriasis and remains one of the safest systemic agents. However, alefacept is the least utilized of all the biologic agents due to the finding that it is only effective in a small proportion of patients and its maximal efficacy is not seen until approximately 6 weeks after treatment completion. Objective: To determine whether intralesional injections with a biologic agent can predict who will be a responder or a non-responder to the medication. Methods: This was a single-center 22-week study consisting of three phases: i) intralesional injection to a target plaque, ii) intramuscular alefacept injections for 12 weeks (standard dose) and iii) post-treatment follow-up. Results: There appears to be a perfect correlation between patients who show a response to an intralesional injection of alefacept to a small, target plaque and those who eventually respond to a full 12-week systemic course of the medication (achieve at least 70% improvement in their PASI scores from baseline) (p = 0.0003). Limitations: This study had a small sample size and was limited by the fact that it was open-label without a control arm. Conclusion: The results from this pilot study demonstrated that alefacept appears to work intralesionally and this may be usable to predict systemic response. More importantly, these results strongly suggest that a biologic agent can work locally - a novel concept that contradicts the common notion that biologic agents must work "systemically".

Abnormal Expression of Collagen IV in Lens Activates Unfolded Protein Response Resulting in Cataract*  

PubMed Central

Human diseases caused by mutations in extracellular matrix genes are often associated with an increased risk of cataract and lens capsular rupture. However, the underlying mechanisms of cataract pathogenesis in these conditions are still unknown. Using two different mouse models, we show that the accumulation of collagen chains in the secretory pathway activates the stress signaling pathway termed unfolded protein response (UPR). Transgenic mice expressing ectopic Col4a3 and Col4a4 genes in the lens exhibited activation of IRE1, ATF6, and PERK associated with expansion of the endoplasmic reticulum and attenuation of general protein translation. The expression of the transgenes had adverse effects on lens fiber cell differentiation and eventually induced cell death in a group of transgenic fiber cells. In Col4a1+/?ex40 mutant mice, the accumulation of mutant chains also caused low levels of UPR activation. However, cell death was not induced in mutant lenses, suggesting that low levels of UPR activation are not proapoptotic. Collectively, the results provide in vivo evidence for a role of UPR in cataract formation in response to accumulation of terminally unfolded proteins in the endoplasmic reticulum.

Initial results from the coupled magnetosphere-ionosphere-thermosphere model: thermosphere-ionosphere responses  

NASA Astrophysics Data System (ADS)

The thermosphere-ionosphere nested grid (TING) model has been successfully coupled with the Lyon-Fedder-Mobarry (LFM) global magnetosphere MHD code. The coupling between these models is two-way: the LFM provides the TING model with global electric fields and precipitating electron energy fluxes, and the TING model feeds ionospheric conductances back to the LFM. This code coupling enables studies of the global energy budget of the magnetosphere-ionosphere-thermosphere system. In this paper, we present simulation results from the coupled magnetosphere-ionosphere-thermosphere (CMIT) model under solar minimum, northern hemisphere summer conditions. The IMF input to the CMIT model changed its direction every 4 h. Comparisons are made between the simulated results of the CMIT model and those of the stand-alone TING model. It is found that the CMIT model predicted higher cross polar cap potential drops than the empirical model used by the stand-alone TING model. The energy input to the upper atmosphere by precipitating electrons, however, was much lower in the CMIT model during the southward IMF interval. The simulated responses of the thermosphere and ionosphere were also significantly different. As a result of the greater Joule heating calculated in the CMIT model, neutral temperatures and winds were significantly enhanced in the CMIT model in comparison with the stand-alone TING model.

Cognitive Biases Questionnaire for Psychosis.  

PubMed

Objective:The Cognitive Biases Questionnaire for psychosis (CBQp) was developed to capture 5 cognitive distortions (jumping to conclusions, intentionalising, catastrophising, emotional reasoning, and dichotomous thinking), which are considered important for the pathogenesis of psychosis. Vignettes were adapted from the Cognitive Style Test (CST),(1) relating to "Anomalous Perceptions" and "Threatening Events" themes.Method:Scale structure, reliability, and validity were investigated in a psychosis group, and CBQp scores were compared with those of depressed and healthy control samples.Results:The CBQp showed good internal consistency and test-retest reliability. The 5 biases were not independent, with a 2-related factor scale providing the best fit. This structure suggests that the CBQp assesses a general thinking bias rather than distinct cognitive errors, while Anomalous Perception and Threatening Events theme scores can be used separately. Total CBQp scores showed good convergent validity with the CST, but individual biases were not related to existing tasks purporting to assess similar reasoning biases. Psychotic and depressed populations scored higher than healthy controls, and symptomatic psychosis patients scored higher than their nonsymptomatic counterparts, with modest relationships between CBQp scores and symptom severity once emotional disorders were partialled out. Anomalous Perception theme and Intentionalising bias scores showed some specificity to psychosis.Conclusions:Overall, the CBQp has good psychometric properties, although it is likely that it measures a different construct to existing tasks, tentatively suggested to represent a bias of interpretation rather than reasoning, judgment or decision-making processes. It is a potentially useful tool in both research and clinical arenas. PMID:23413104

Academic job satisfaction questionnaire: Construction and validation in Saudi Arabia  

PubMed Central

Background: Colleges and universities are becoming increasingly accountable for teaching outcomes in order to meet rigorous accreditation standards. Job satisfaction (JS) seems more difficult to measure in the academic field in view of the complexity of roles, duties and responsibilities. Objectives: To compile and determine the psychometric properties of a proposed Academic Job Satisfaction Questionnaire (AJSQ) suitable for university faculty, and amenable to future upgrading. Materials and Methods: A 46-item five-option Likert-type draft questionnaire on JS was distributed for anonymous self-reporting by all the academic staff of five colleges in University of Dammam (n=340). The outcome measures were (1) factor analysis of the questionnaire items, (2) intra-factor ?-Coefficient of Internal Consistency Reliability, (3) inter-factor correlations, (4) comparison of psychometric properties in separately analyzed main faculty subgroups. Results: The response rate was 72.9 percent. Factor analysis extracted eight factors which conjointly explained 60.3 percent of the variance in JS. These factors, in descending order of eigenvalue, were labeled “Authority”, “Supervision”, “Policies and Facilities”, “My Work Itself”, “Interpersonal Relationships”, “Commitment”, “Salary” and “Workload”. Cronbach's-? ranged from 0.90 in Supervision to 0.63 in Salary and Workload. All inter-factor correlations were positive and significant, ranging from 0.65 to 0.23. The psychometric properties of the instrument in separately analyzed subgroups divided by sex, nationality, college and clinical duties produced fairly comparable findings. Conclusion: The AJSQ demonstrated good overall psychometric properties in terms of construct validity and internal consistency reliability in both the overall sample and its separately analyzed subgroups. Recommendation: To replicate these findings in larger multicenter samples of academic staff.

The 2010 nephrology quiz and questionnaire: part 2.  

PubMed

Presentation of the Nephrology Quiz and Questionnaire (NQQ) has become an annual "tradition" at the meetings of the American Society of Nephrology. It is a very popular session judged by consistently large attendance. Members of the audience test their knowledge and judgment on a series of case-oriented questions prepared and discussed by experts. They can also compare their answers in real time, using audience response devices, to those of program directors of nephrology training programs in the United States, acquired through an Internet-based questionnaire. As in the past, the topics covered were transplantation, fluid and electrolyte disorders, end-stage renal disease and dialysis, and glomerular disorders. Two challenging cases representing each of these categories along with single best answer questions were prepared by a panel of experts (Drs. Hricik, Palmer, Bargman, and Fervenza, respectively). The "correct" and "incorrect" answers then were briefly discussed, after the audience responses and the results of the questionnaire were displayed. The 2010 version of the NQQ was exceptionally challenging, and the audience, for the first time, gained a better overall correct answer score than the program directors, but the margin was small. Last month we presented the transplantation and fluid and the electrolyte cases; in this issue we present the remaining end-stage renal disease and dialysis and the glomerular disorder cases. These articles try to recapitulate the session and reproduce its educational value for a larger audience--that of the readers of the Clinical Journal of the American Society of Nephrology. Have fun.

Caregiver's Feeding Styles Questionnaire: Establishing Cutoff Points  

PubMed Central

Researchers use the Caregiver’s Feeding Styles Questionnaire (CFSQ) to categorize parent feeding into authoritative, authoritarian, indulgent, and uninvolved styles. The CFSQ assesses self-reported feeding and classifies parents using median splits, which are used in a substantial body of parenting literature and allow for direct comparison across studies, on dimensions of demandingness and responsiveness. No national norms currently exist for the CFSQ. This paper establishes and recommends cutoff points most relevant for low-income, minority US samples researchers and clinicians can use to assign parents to feeding styles. Median scores for 5 studies are examined and the average across these studies reported.

Vessel Noise Affects Beaked Whale Behavior: Results of a Dedicated Acoustic Response Study  

PubMed Central

Some beaked whale species are susceptible to the detrimental effects of anthropogenic noise. Most studies have concentrated on the effects of military sonar, but other forms of acoustic disturbance (e.g. shipping noise) may disrupt behavior. An experiment involving the exposure of target whale groups to intense vessel-generated noise tested how these exposures influenced the foraging behavior of Blainville’s beaked whales (Mesoplodon densirostris) in the Tongue of the Ocean (Bahamas). A military array of bottom-mounted hydrophones was used to measure the response based upon changes in the spatial and temporal pattern of vocalizations. The archived acoustic data were used to compute metrics of the echolocation-based foraging behavior for 16 targeted groups, 10 groups further away on the range, and 26 non-exposed groups. The duration of foraging bouts was not significantly affected by the exposure. Changes in the hydrophone over which the group was most frequently detected occurred as the animals moved around within a foraging bout, and their number was significantly less the closer the whales were to the sound source. Non-exposed groups also had significantly more changes in the primary hydrophone than exposed groups irrespective of distance. Our results suggested that broadband ship noise caused a significant change in beaked whale behavior up to at least 5.2 kilometers away from the vessel. The observed change could potentially correspond to a restriction in the movement of groups, a period of more directional travel, a reduction in the number of individuals clicking within the group, or a response to changes in prey movement.

Barcoded Pyrosequencing Reveals That Consumption of Galactooligosaccharides Results in a Highly Specific Bifidogenic Response in Humans  

PubMed Central

Prebiotics are selectively fermented ingredients that allow specific changes in the gastrointestinal microbiota that confer health benefits to the host. However, the effects of prebiotics on the human gut microbiota are incomplete as most studies have relied on methods that fail to cover the breadth of the bacterial community. The goal of this research was to use high throughput multiplex community sequencing of 16S rDNA tags to gain a community wide perspective of the impact of prebiotic galactooligosaccharide (GOS) on the fecal microbiota of healthy human subjects. Fecal samples from eighteen healthy adults were previously obtained during a feeding trial in which each subject consumed a GOS-containing product for twelve weeks, with four increasing dosages (0, 2.5, 5, and 10 gram) of GOS. Multiplex sequencing of the 16S rDNA tags revealed that GOS induced significant compositional alterations in the fecal microbiota, principally by increasing the abundance of organisms within the Actinobacteria. Specifically, several distinct lineages of Bifidobacterium were enriched. Consumption of GOS led to five- to ten-fold increases in bifidobacteria in half of the subjects. Increases in Firmicutes were also observed, however, these changes were detectable in only a few individuals. The enrichment of bifidobacteria was generally at the expense of one group of bacteria, the Bacteroides. The responses to GOS and the magnitude of the response varied between individuals, were reversible, and were in accordance with dosage. The bifidobacteria were the only bacteria that were consistently and significantly enriched by GOS, although this substrate supported the growth of diverse colonic bacteria in mono-culture experiments. These results suggest that GOS can be used to enrich bifidobacteria in the human gastrointestinal tract with remarkable specificity, and that the bifidogenic properties of GOS that occur in vivo are caused by selective fermentation as well as by competitive interactions within the intestinal environment.

Loss of serum response factor in keratinocytes results in hyperproliferative skin disease in mice  

PubMed Central

The transcription factor serum response factor (SRF) plays a crucial role in the development of several organs. However, its role in the skin has not been explored. Here, we show that keratinocytes in normal human and mouse skin expressed high levels of SRF but that SRF expression was strongly downregulated in the hyperproliferative epidermis of wounded and psoriatic skin. Keratinocyte-specific deletion within the mouse SRF locus during embryonic development caused edema and skin blistering, and all animals died in utero. Postnatal loss of mouse SRF in keratinocytes resulted in the development of psoriasis-like skin lesions. These lesions were characterized by inflammation, hyperproliferation, and abnormal differentiation of keratinocytes as well as by disruption of the actin cytoskeleton. Ultrastructural analysis revealed markedly reduced cell-cell and cell-matrix contacts and loss of cell compaction in all epidermal layers. siRNA-mediated knockdown of SRF in primary human keratinocytes revealed that the cytoskeletal abnormalities and adhesion defects were a direct consequence of the loss of SRF. In contrast, the hyperproliferation observed in vivo was an indirect effect that was most likely a consequence of the inflammation. These results reveal that loss of SRF disrupts epidermal homeostasis and strongly suggest its involvement in the pathogenesis of hyperproliferative skin diseases, including psoriasis.

The negative affect repair questionnaire: factor analysis and psychometric evaluation in three samples  

PubMed Central

Background Negative affect and difficulties in its regulation have been connected to several adverse psychological consequences. While several questionnaires exist, it would be important to have a theory-based measure that includes clinically relevant items and shows good psychometric properties in healthy and patient samples. This study aims at developing such a questionnaire, combining the two Gross [1] scales Reappraisal and Suppression with an additional response-focused scale called Externalizing Behavioral Strategies covering clinically relevant items. Methods The samples consisted of 684 students (mean age?=?23.3, SD?=?3.5; 53.6% female) and 369 persons with mixed mental disorders (mean age?=?36.0 SD?=?14.6; 71.2% female). Items for the questionnaire were derived from existing questionnaires and additional items were formulated based on suggestions by clinical experts. All items start with “When I don’t feel well, in order to feel better…”. Participants rated how frequently they used each strategy on a 5-point Likert scale. Confirmatory Factor Analyses were conducted to verify the factor structure in two separate student samples and a clinical sample. Group comparisons and correlations with other questionnaires were calculated to ensure validity. Results After modification, the CFA showed good model fit in all three samples. Reliability scores (Cronbach’s ?) for the three NARQ scales ranged between .71 and .80. Comparisons between students and persons with mental disorders showed the postulated relationships, as did comparisons between male and female students and persons with or without Borderline Personality Disorder. Correlations with other questionnaires suggest the NARQ’s construct validity. Conclusions The results indicate that the NARQ is a psychometrically sound and reliable measure with practical use for therapy planning and tracking of treatment outcome across time. We advocate the integration of the new response-focused strategy in the Gross’s model of emotion regulation.

Biological responses to space: results of the experiment "Exobiological Unit" of ERA on EURECA I.  

PubMed

Spores of different strains of Bacillus subtilis and the Escherichia coli plasmid pUC19 were exposed to selected conditions of space (space vacuum and/or defined wavebands and intensities of solar ultraviolet radiation) in the experiment ER 161 "Exobiological Unit" of the Exobiology Radiation Assembly (ERA) on board of the European Retrievable Carrier (EURECA). After the approximately 11 months lasting mission, their responses were studied in terms of survival, mutagenesis in the his (B. subtilis) or lac locus (pUC19), induction of DNA strand breaks, efficiency of DNA repair systems, and the role of external protective agents. The data were compared with those of a simultaneously running ground control experiment. The survival of spores treated with the vacuum of space, however shielded against solar radiation, is substantially increased, if they are exposed in multilayers and/or in the presence of glucose as protective, whereas all spores in "artificial meteorites", i.e. embedded in clays or simulated Martian soil, are killed. Vacuum treatment leads to an increase of mutation frequency in spores, but not in plasmid DNA. Extraterrestrial solar ultraviolet radiation is mutagenic, induces strand breaks in the DNA and reduces survival substantially; however, even at the highest fluences, i.e. 3 x 10(8) J m-2, a small but significant fraction of spores survives the insolation. Action spectroscopy confirms results of previous space experiments of a synergistic action of space vacuum and solar UV radiation with DNA being the critical target. PMID:11542695

Dual effects of phytoestrogens result in u-shaped dose-response curves.  

PubMed Central

Endocrine disruptors can affect the endocrine system without directly interacting with receptors, for example, by interfering with the synthesis or metabolism of steroid hormones. The aromatase that converts testosterone to 17beta-estradiol is a possible target. In this paper we describe an assay that simultaneously detects aromatase inhibition and estrogenicity. The principle is similar to that of other MCF-7 estrogenicity assays, but with a fixed amount of testosterone added. The endogenous aromatase activity in MCF-7 cells converts some of the testosterone to 17beta-estradiol, which is assayed by quantifying differences in the expression level of the estrogen-induced pS2 mRNA. Potential aromatase inhibitors can be identified by a dose-dependent reduction in the pS2 mRNA expression level after exposure to testosterone and the test compound. Using this assay, we have investigated several compounds, including synthetic chemicals and phytoestrogens, for aromatase inhibition. The phytoestrogens, except genistein, were aromatase inhibitors at low concentrations (< 1 micro M) but estrogenic at higher concentrations (greater than or equal to 1 micro M), resulting in U-shaped dose-response curves. None of the tested synthetic chemicals were aromatase inhibitors. The low-dose aromatase inhibition distinguished phytoestrogens from other estrogenic compounds and may partly explain reports about antiestrogenic properties of phytoestrogens. Aromatase inhibition may play an important role in the protective effects of phytoestrogens against breast cancer.

Development of a nutrition knowledge questionnaire for obese adults  

PubMed Central

Background and objective The aim of this study was to develop a questionnaire for assessing nutritional knowledge among overweight adults. The questionnaire should reveal knowledge about current dietary recommendations, sources of nutrients, everyday food choices, and conditions related to overweight. Design The first draft of the nutrition knowledge questionnaire (113 items) was based on literature review. To ensure content validity and expert-assessed face validity, an expert panel examined the questionnaire. Thereafter, the questionnaire was tested for user friendliness and ambiguity by five students. The questionnaire was pilot tested in a group of obese adults, similar to the target group. The results were analyzed for item difficulty and internal consistency and comments made by respondents were taken into account. Two student groups, differing in nutritional expertise, answered the questionnaire on two occasions to test construct validity and test–retest reliability. After the retest, a total overview of the questionnaire was made by the expert panel. The final questionnaire consisted of 91 items. Subjects The pilot study was conducted in obese adults waiting for a gastric bypass operation (n=33). Construct validity (n=34) and test–retest reliability (n=27) was tested in two student groups: public health nutrition students and construction students. Results Results from the pilot study showed that internal consistency of the three first sections together was 0.84, measured by Cronbach's ?. Test of construct validity showed that public health nutrition students scored significantly better than construction students (p<0.001 for all sections), and test–retest reliability for all sections together was 0.82 (Pearson's r). Conclusion The knowledge questionnaire had reasonable content-, face-, and construct validities and overall good reliability. The questionnaire can be a useful tool for measuring nutrition knowledge among obese adults.

Protein C Mutation (A267T) Results in ER Retention and Unfolded Protein Response Activation  

PubMed Central

Background Protein C (PC) deficiency is associated with a high risk of venous thrombosis. Recently, we identified the PC-A267T mutation in a patient with PC deficiency and revealed by in vitro studies decreased intracellular and secreted levels of the mutant. The aim of the present study was to characterize the underlying mechanism(s). Methodology/Principal Findings CHO-K1 cells stably expressing the wild-type (PC-wt) or the PC mutant were generated. In order to examine whether the PC mutant was subjected to increased intracellular degradation, the cells were treated with several inhibitors of various degradation pathways and pulse-chase experiments were performed. Protein-chaperone complexes were analyzed by treating the cells with a cross-linker followed by Western blotting (WB). Expression levels of the immunoglobulin-binding protein (BiP) and the phosphorylated eukaryotic initiation factor 2? (P-eIF2?), both common ER stress markers, were determined by WB to examine if the mutation induced ER stress and unfolded protein response (UPR) activation. We found no major differences in the intracellular degradation between the PC variants. The PC mutant was retained in the endoplasmic reticulum (ER) and had increased association with the Grp-94 and calreticulin chaperones. Retention of the PC-A267T in ER resulted in UPR activation demonstrated by increased expression levels of the ER stress markers BiP and P-eIF2? and caused also increased apoptotic activity in CHO-K1 cells as evidenced by elevated levels of DNA fragmentation. Conclusions/Significance The reduced intracellular level and impaired secretion of the PC mutant were due to retention in ER. In contrast to other PC mutations, retention of the PC-A267T in ER resulted in minor increased proteasomal degradation, rather it induced ER stress, UPR activation and apoptosis.

Global and Regional Climate Responses Solar Radiation Management: Results from a climateprediction.net Geoengineering Experiment  

NASA Astrophysics Data System (ADS)

To date modeling studies suggest that, while significant hydrological anomalies could result from the artificial addition of reflecting aerosols in the stratosphere for the purpose of solar radiation management (SRM), even at the regional level such a geoengineered world would bear a much closer resemblance to a low CO2 world, than to an unmodified high CO2 world. These previous modeling studies have generally compared one or two SRM forcing scenarios to various business-as-usual controls. However, such approaches cannot provide much information about regional sensitivities to the levels of SRM that might realistically result. Should engaging in SRM every be seriously contemplated, such regional analysis of a range of realistic scenarios will be an essential input to any process of geopolitical decision-making. Here we present the results from a large-ensemble experiment that used the HadCM3L GCM, implemented through climateprediction.net. The analysis examines 135 globally-uniform stratospheric optical depth modification scenarios designed to stabilize global temperatures under SRES A1B. Scenarios were tested using ten-member subensembles which made small perturbations to initial conditions. All simulations use identical standard settings of model physics parameters and are initiated from historically-forced runs from 1920-2005. A total of 7,331 simulations of the years 2000-2080 were performed for this experiment using computing resources donated by the general public. Our analysis of regional temperature and precipitation anomalies, normalized to account for variability, shows that SRM compensations for anthropogenic greenhouse gas forcing do generally return regional climates closer to their baseline climate states than the no-geoengineering, business-as-usual scenarios. However, we find that the magnitudes and sensitivities of regional responses to this type of activity, as modeled in HadCM3L, are highly variable. As the amount of SRM increases to compensate for rising greenhouse gas concentrations in the atmosphere, regions, such as Eastern China and India, migrate away from their baseline climate states in different ways, illustrating the impossibility of simultaneous stabilization of regional climates. A number of policy-relevant questions about SRM activities have not yet been addressed in the literature. These include whether regional climate factors become more or less variable under SRM as compared to no-geoengineering and how long after deployment of geoengineering forcings it may be before one can determine the global and regional effects with some confidence. We present new analyses in which we exploit our large ensemble to explore several such questions.

Pneumonitis in bone marrow transplant recipients results from a local immune response.  

PubMed Central

Eighteen recipients of allogeneic T cell-depleted bone marrow who developed 22 episodes of interstitial pneumonitis were investigated by bronchoalveolar lavage for the cause of pneumonitis. The cells obtained were examined using a panel of monoclonal antibodies with immunocytochemical techniques to identify lymphocyte subsets and the presence of surface molecules indicative of lymphocyte activation. The majority of patients had an excess of lymphocytes in lavage and most of these cells were positively stained with the McAb recognizing the CD8 antigen (suppressor/cytotoxic type T cells). Although the proportions of CD4+ (helper type) T cells were below normal, the absolute numbers were within normal limits, thus the CD4:CD8 ratio was consistently 1:1 or less. A large proportion of the CD8+ cells displayed HLA-DR molecules (RFDR1+), interleukin-2 (IL-2) receptors (CD25+) and high concentration of CD7 antigen (RFT2+). Further analysis revealed that most CD8+ cells were CD5+ (RFT1+) yet a large proportion (20-40%) were CD5-. A majority of CD8+ cells was also CD38+ (RFT10+) and Leu7+. No clear correlation between the emergence of a raised proportion of activated CD8+ cells and diagnosed cytomegalovirus infection was found. These results demonstrate, however, that cells with the phenotype of the resident T cells of the bronchial epithelium (CD8+CD5-) emerge to the air spaces and express activation markers. This raises the intriguing paradox of an aggressive local immune response occurring in an otherwise immunosuppressed group of patients.

Development of a Fast-Response Ultraviolet Absorption Ozone Sensor: Design and First Results  

NASA Astrophysics Data System (ADS)

Ozone is one of the most important trace gases in the atmosphere. In the stratosphere it absorbs solar ultraviolet radiation, serving a dual role by protecting life on earth from UV damage and by influencing the temperature structure of that part of the atmosphere. In the lower troposphere, ozone is a pollutant formed by photochemical transformations of anthropogenic emissions such as nitrogen oxides and hydrocarbons. In the tropopause region, ozone serves as a powerful greenhouse gas by virtue of its absorption feature at 9.6 ?m. Hence, gaining a better understanding of the distribution and variability of ozone abundances and the chemical and dynamical processes that determine the distributions is a critical scientific objective. We have designed a fast-response sensor to measure ozone by ultraviolet absorption. An early version of this instrument flew on two airborne campaigns - COBRA (1999, UND Cessna Citation) and SOLVE (1999/00, DC-8, Arctic) - where it provided 10-second measurements of ozone throughout the upper troposphere and lower stratosphere. Recent laboratory work has resulted in vastly improved instrument electronics, allowing for 10 Hz measurements with a precision of better than 20 ppb. Instrument performance and sensitivity have been demonstrated with ground-based measurements in the Antarctic and airborne measurements from the NASA WB-57F during the Plume Ultrafast Measurements Acquisition (PUMA) project. The instrument is compact, lightweight (less than 35 lbs), and power-efficient (less than 100 W), so it is also ideally suited to the UAV environment where power and payload weight are restricted. In this presentation we describe the instrument design and illustrate its performance throughout the troposphere and lower stratosphere.

Factorial validity of the short-form McGill pain questionnaire (SF-MPQ)  

Microsoft Academic Search

Although widely used, there have been few investigations of the factorial validity of the short-form McGill Pain Questionnaire (SF-MPQ; Melzack, 1987). Confirmatory factor analysis was performed on item responses to the SF-MPQ obtained from 188 patients with chronic back pain. Consistent with the original structure proposed by Melzack (1987), results indicated that the SF-MPQ is best represented by a two-factor

Dimensions of the Dysexecutive Questionnaire (DEX) examined using Rasch analysis.  

PubMed

Executive dysfunction is very broad term used to capture a range of interacting high-level cognitive, emotional and behavioural difficulties, commonly seen after acquired brain injury (ABI). Many argue that the concept of executive functioning should be subdivided into several separate dimensions. In this study we explore the dimensional structure of a tool designed to assess level of executive functioning, the Dysexecutive (DEX) Questionnaire (Burgess, Alderman, Wilson, Evans, & Emslie, 1996), in order to inform theoretical conceptualisations of executive functioning and improve measurement precision in rehabilitation centres. Rasch analysis was undertaken on the responses of 363 people with ABI to the DEX. Overall, the questionnaire did not perform as a unidimensional, interval-level scale of executive functioning, suggesting that it measures more than one psychological construct. Most subscales previously proposed using factor analysis, including those suggested in the DEX manual, did not perform as unidimensional interval-level scales either. Several new subscales in keeping with theoretical conceptualisations of the different dimensions of executive functioning are proposed, alongside suggestions for revision of the wording and scoring of some of the items in the DEX. These results provide a platform for future evaluation of executive function rehabilitation programmes. PMID:21181602

Loss of transcription factor early growth response gene 1 results in impaired endochondral bone repair  

Microsoft Academic Search

Transcription factors that play a role in ossification during development are expected to participate in postnatal fracture repair since the endochondral bone formation that occurs in embryos is recapitulated during fracture repair. However, inherent differences exist between bone development and fracture repair, including a sudden disruption of tissue integrity followed by an inflammatory response. This raises the possibility that repair-specific

Kangaroo Care (skin contact) reduces crying response to pain in preterm neonates: pilot results.  

PubMed

Crying commonly occurs in response to heel stick and adversely affects the infant's physiologic stability. Minimal crying in response to pain is desired. "Kangaroo Care," skin contact between mother and infant, reduces pain and may reduce crying in response to pain. The purpose of this pilot study was to test Kangaroo Care's effect on the preterm infant's audible and inaudible crying response to heel stick. Inaudible crying has not been previously studied. A prospective randomized cross-over study with 10 preterm infants 2-9 days old (30-32 weeks' postmenstrual age) was conducted. Infants were randomly assigned to two sequences (sequence A: day 1 heel stick in Kangaroo Care [after 30 min of prone skin contact upright between maternal breasts] and day 2 heel stick in incubator [inclined, nested and prone]; or sequence B: opposite of sequence A) was conducted. Videotapes of baseline, heel warming, heel stick, and recovery phases were scored for audible and inaudible crying times. Audible and inaudible crying times for each subject in each phase were summed and analyzed by repeated-measures analysis of variance. Subject characteristics did not differ between those in the two sequences. Crying time differed between the study phases on both days (p response to heel stick in medically stable preterm infants, a definitive study is merited before making recommendations. PMID:18513662

The Application of a Primary Science Delivery Evaluation Questionnaire  

NASA Astrophysics Data System (ADS)

The purpose of this investigation was to apply a validated curriculum evaluation instrument, the Science Curriculum Implementation Questionnaire (SCIQ), in an educational context in which a science curriculum review had recently been completed and, by so doing, ascertain the accuracy and potential value of the instrument as a curriculum delivery evaluative tool. The study begins by exploring the themes generated from an extensive case study attempting to identify the broad and complex factors influencing science program delivery at a large urban intermediate (Years 7 and 8) school in New Zealand. Following this, the results of the subsequent application of the SCIQ in the case study school are discussed. Responses to the SCIQ reaffirmed the themes identified in the case study and, by way of standard deviation analysis, gave a similar description of the variability in the staff perceptions pertaining to the factors influencing science program delivery. Limitations and recent practical applications of the SCIQ are also discussed.

Dermatophytosis in zoo macropods: a questionnaire study.  

PubMed

Limited published data are available on dermatophytosis in zoo macropods, despite anecdotal reports of disease occurrence and recurrent mob outbreaks. The aim of this questionnaire study was to analyze data from Australian and international zoos to evaluate estimated disease prevalence in zoos housing macropods, affected macropod species, causative organisms, predisposing factors, clinical presentations, diagnostics, treatments, and disease risk management. Two questionnaires (initial detailed and subsequent brief) were distributed via email to zoo veterinarians, with an estimated response rate of 23%. The overall estimated disease prevalence from responding zoos was 28%, with 73% of responding Australian zoos and 14% of responding non-Australian zoos reporting disease. The first cases of confirmed and suspected dermatophytosis in several macropod species and in association with Trichophyton verrucosum and Trichophyton mentagrophytes var. nodulare are reported, with young red kangaroos (Macropus rufus) appearing predisposed. Diagnosis was most commonly based on fungal culture or presumptively on typical clinical signs of minimally/nonpruritic alopecia, crusting, and scaling distributed most frequently on the tail, pinnae, and hind limbs. Both disease resolution without treatment and resolution after an average of 1 to 2 mo of treatment were reported. PMID:24063082

High fat feeding results in a decrease in insulin responsiveness of isolated solei  

SciTech Connect

The relationship between diet and insulin responsiveness was examined in isolated solei from 6 week old female Sprague-Dawley rats. Weanling rats were fed either a high fat (HF) (67%kcal) or a high carbohydrate diet (HC) (67% kcal) for 21 days. A significant decrease in plasma insulin (I) but not glucose was observed in the HF fed rats. Insulin stimulated (IS) glucose (G) metabolism was examined using a maximal concentration of I (20 mU/m1). G uptake was estimated using /sup 14/C-2 deoxyglucose (2DG). Basal and IS 2DG uptake decreased in HF rats. However, I sensitivity but not responsiveness remained intact in the HF rats. Total G utilization (GU) was estimated by the sum of the rate of formation of: /sup 3/H/sub 2/O from 5-/sup 3/H-glucose (glycolysis- (GL)) and /sup 3/H-glycogen (GLY). IS GU decreased in HF versus HC fed rats. I failed to stimulate GL while GLY remained sensitive. Glucose oxidation (GO) was measured by /sup 14/CO/sub 2/. I failed to stimulated GO. Intracellular metabolite concentrations (IC) were measured in solei from HF and HC fed rats. IS IC-G6P decreased in HF compared to HC fed rats. Basal IC-F6P but not IC-F 1.6 BP increased in HF compared to HC fed rats. I failed to stimulate an increase in IC-F 1,6BP concentrations. Glycolytic activators were determined. HF produced a significant decrease in F2, 6BP concentration when compared to HC rats. Prostaglandins (PG) have been implicated in mediating insulin action. HF produced a significant decrease in basal and insulin stimulated PGE/sub 2/. These data demonstrate that postreceptor - postmembrane alterations are in part responsible for the decreased insulin responsiveness observed after HF feeding.

Preparation of neuroradiologic procedures: a questionnaire.  

PubMed

Responses to a questionnaire sent to members of the ASNR indicated that most neuroradiologists do not believe extensive precautions reduce the infection rate for the routine patient undergoing myelography or femoral cerebral angiography. Most neuroradiologists queried do not routinely perform a surgical scrub before each procedure. Most wear sterile gloves and gowns, but not caps or masks. They do prepare the puncture site in a meticulous manner. Concern was expressed for the likelihood of causing infection in patients undergoing extensive procedures such as angioplasty or embolization, puncturing femoral grafts, or in the presence of artificial heart valves. The increased likelihood of incurring infections in diabetic or immunosuppressed patients was also expressed. In these patients, meticulous surgical technique was deemed mandatory. PMID:6421121

Results of animal studies suggest a nonlinear dose-response relationship for benzene effects  

SciTech Connect

Considering the very large industrial usage of benzene, studies in risk assessment aimed at the evaluation of carcinogenic risk at low levels of exposure are important. Animal data can offer indications about what could happen in humans and provide more diverse information than epidemiological data with respect to dose-response consideration. The authors have considered experiments investigating metabolism, short-term genotoxicity tests, DNA adduct formation, and carcinogenicity long-term tests. According to the different experiments, a saturation of benzene metabolism and benzene effects in terms of genotoxicity seems evident above 30 to 100 ppm. Below 30 to 60 ppm the initiating effect of benzene seems to be linear for a large interval of dosages, at least judging from DNA adduct formation. Potential lack of a promoting effect of benzene (below 10 ppm) could generate a sublinear response at nontoxic levels of exposure. This possibility was suggested by epidemiological data in humans and is not confirmed or excluded by their observations with animals.

Stimuli-responsive topological change of microstructured surfaces and the resultant variations of wetting properties.  

PubMed

It is now well established that topological microstructures play a key role in the physical properties of surfaces. Stimulus-induced variations of topological microstructure should therefore lead to a change in the physical properties of microstructured responsive surfaces. In this paper, we demonstrate that roughness changes alter the wetting properties of responsive organic surfaces. Oriented nematic liquid crystalline elastomers (LCEs) are used to construct the microstructured surfaces via a replica molding technique. The topological microstructure of the surfaces covered with micropillars changes with temperature, due to the reversible contraction of the LCE pillars along the long axis at the nematic-to-isotropic phase transition. This is directly observed for the first time under environmental scanning electron microscopy (E-SEM). A high boiling point liquid, glycerol, is used to continuously monitor the contact angle change with temperature. The glycerol contact angle of the microstructured surfaces covered with small pillars decreases from 118° at room temperature to 80° at 140 °C, corresponding to a transition from Cassie state to Wenzel state.

Treatment Response and Long Term Follow-up Results of Nonspecific Interstitial Pneumonia  

PubMed Central

The purpose of this study was to investigate the long-term clinical course of non-specific interstitial pneumonia (NSIP) and to determine which factors are associated with a response to steroid therapy and relapse. Thirty-five patients with pathologically proven NSIP were included. Clinical, radiological, and laboratory data were reviewed retrospectively. The male-to-female ratio was 7:28 (median age, 52 yr). Thirty (86%) patients responded to steroid therapy, and the median follow-up was 55.2 months (range, 15.9-102.0 months). Five patients (14%) showed sustained disease progression and three died despite treatment. In the five with sustained disease progression, NSIP was associated with various systemic conditions, and the seropositivity of fluorescent antinuclear antibody was significantly associated with a poor response to steroids (P = 0.028). The rate of relapse was 25%, but all relapsed patients improved after re-treatment. The initial dose of steroids was significantly low in the relapse group (P = 0.020). In conclusion, progression is associated with various systemic conditions in patients who show progression. A low dose of initial steroids is significantly associated with relapse.

The development of a questionnaire to describe science teacher communication behavior in Taiwan and Australia  

NASA Astrophysics Data System (ADS)

Teachers contribute enormously to a positive social climate in science classes, particularly through their communication with students. This article describes the development and validation of a questionnaire, the Teacher Communication Behavior Questionnaire (TCBQ) (see pp. 723-726), which assesses student perceptions of the following five important teacher behaviors: Challenging, Encouragement and Praise, Non-Verbal Support, Understanding and Friendly, and Controlling. The TCBQ was administered to 1202 students from 30 classes in Taiwan and to 301 students from 12 classes in Australia. The reliability and factorial validity of the TCBQ were found to be satisfactory for both the Taiwanese and Australian data. To further validate the questionnaire and understand the differences in teacher behavior according to the perceptions of students from the two countries, a qualitative approach was used. Students were interviewed (two from each of five classes) in both Taiwan and Australia. The interview questions focused on these students' responses to selected questionnaire items. The results obtained from the interviews supported and helped explain the quantitative results. In an application of the TCBQ in both countries, students' perceptions on four of the scales of the TCBQ were associated with their attitudes to their science classes.

Inner ear is a remarkable multiphysical system and its modelling is a great challenge. The approach used in this paper aims to reproduce physic with a realistic description of the radial cross section of the cochlea. A 2D-section of the organ of Corti is fully described. Wavenumbers and corresponding modes of propagation are calculated taking into account passive structural responses. The study is extended to six cross sections of the organ of Corti and a large frequency bandwidth from 100 Hz to 3 kHz. Dispersion curves reveal the influence of fluid structure interactions with a dispersive behavior at high frequencies. Longitudinal mechanical coupling provides new interacting modes of propagation.

Stab injury and device implantation within the brain results in inversely multiphasic neuroinflammatory and neurodegenerative responses  

NASA Astrophysics Data System (ADS)

An estimated 25 million people in the US alone rely on implanted medical devices, ˜2.5 million implanted within the nervous system. Even though many devices perform adequately for years, the host response to medical devices often severely limits tissue integration and long-term performance. This host response is believed to be particularly limiting in the case of intracortical microelectrodes, where it has been shown that glial cell encapsulation and localized neuronal cell loss accompany intracortical microelectrode implantation. Since neuronal ensembles must be within ˜50 µm of the electrode to obtain neuronal spikes and local field potentials, developing a better understanding of the molecular and cellular environment at the device-tissue interface has been the subject of significant research. Unfortunately, immunohistochemical studies of scar maturation in correlation to device function have been inconclusive. Therefore, here we present a detailed quantitative study of the cellular events and the stability of the blood-brain barrier (BBB) following intracortical microelectrode implantation and cortical stab injury in a chronic survival model. We found two distinctly inverse multiphasic profiles for neuronal survival in device-implanted tissue compared to stab-injured animals. For chronically implanted animals, we observed a biphasic paradigm between blood-derived/trauma-induced and CNS-derived inflammatory markers driving neurodegeneration at the interface. In contrast, stab injured animals demonstrated a CNS-mediated neurodegenerative environment. Collectively these data provide valuable insight to the possibility of multiple roles of chronic neuroinflammatory events on BBB disruption and localized neurodegeneration, while also suggesting the importance to consider multiphasic neuroinflammatory kinetics in the design of therapeutic strategies for stabilizing neural interfaces.

Does Labeling Prenatal Screening Test Results as Negative or Positive Affect Women's Responses?  

PubMed Central

Objective We tested whether adding interpretive labels (e.g., “negative test”) to prenatal genetic screening test results changes perceived risk and preferences for amniocentesis. Study Design Women (N=1,688) completed a hypothetical pregnancy scenario via the Internet. We randomized participants into two groups: high (12.5/1000) risk of fetal chromosomal problems or low (2/1000) risk. After prenatal screening, estimated risk was identical (5/1000) for all participants, but results were provided either alone or with interpretive labels. Results When receiving test results without labels, all participants react similarly. With labels, participants receiving “positive” or “abnormal” results reported higher perceived risk (p<0.001), greater worry (p<0.001), and greater interest in amniocentesis (57% vs. 37%, p<0.001) than those receiving “negative” or “normal” results. Conclusions Interpretive labels for test results can induce larger changes to women’s risk perceptions and behavioral intentions than numerical results alone do, creating decision momentum. This finding has broad clinical implications for patient-provider communication.

Child abuse: validation of a questionnaire translated into Brazilian Portuguese.  

PubMed

This study sought to validate the Portuguese translation of a questionnaire on maltreatment of children and adolescents, developed by Russell et al. and to test its psychometric properties for use in Brazil. The original questionnaire was translated into Portuguese using a standardized forward-backward linguistic translation method. Both face and content validity were tested in a small pilot study (n = 8). In the main study, a convenience sample of 80 graduate dentistry students with different specialties, from Curitiba, PR, Brazil, were invited to complete the final Brazilian version of the questionnaire. Discriminant validity was assessed by comparing the results obtained from the questionnaire for different specialties (pediatric dentistry, for example). The respondents completed the questionnaire again after 4 weeks to evaluate test-retest reliability. The comparison of test versus retest questionnaire answers showed good agreement (kappa > 0.53, intraclass correlation > 0.84) for most questions. In regard to discriminant validity, a statistically significant difference was observed only in the experience and interest domains, in which pediatric dentists showed more experience with and interest in child abuse compared with dentists of other specialties (Mann-Whitney test, p < 0.05). The Brazilian version of the questionnaire was valid and reliable for assessing knowledge regarding child abuse by Portuguese-speaking dentists. PMID:23538428

The effect of ambient pressure on well chamber response: Monte Carlo calculated results for the HDR 1000 Plus  

SciTech Connect

The determination of the air kerma strength of a brachytherapy seed is necessary for effective treatment planning. Well ionization chambers are used on site at therapy clinics to determine the air kerma strength of seeds. In this work, the response of the Standard Imaging HDR 1000 Plus well chamber to ambient pressure is examined using Monte Carlo calculations. The experimental work examining the response of this chamber as well as other chambers is presented in a companion paper. The Monte Carlo results show that for low-energy photon sources, the application of the standard temperature pressure P{sub TP} correction factor produces an over-response at the reduced air densities/pressures corresponding to high elevations. With photon sources of 20 to 40 keV, the normalized P{sub TP} corrected chamber response is as much as 10% to 20% over unity for air densities/pressures corresponding to an elevation of 3048 m (10000 ft) above sea level. At air densities corresponding to an elevation of 1524 m (5000 ft), the normalized P{sub TP}-corrected chamber response is 5% to 10% over unity for these photon sources. With higher-energy photon sources (>100 keV), the normalized P{sub TP} corrected chamber response is near unity. For low-energy {beta} sources of 0.25 to 0.50 MeV, the normalized P{sub TP}-corrected chamber response is as much as 4% to 12% over unity for air densities/pressures corresponding to an elevation of 3048 m (10000 ft) above sea level. Higher-energy {beta} sources (>0.75 MeV) have a normalized P{sub TP} corrected chamber response near unity. Comparing calculated and measured chamber responses for common {sup 103}Pd- and {sup 125}I-based brachytherapy seeds show agreement to within 2.7% and 1.9%, respectively. Comparing MCNP calculated chamber responses with EGSnrc calculated chamber responses show agreement to within 3.1% at photon energies of 20 to 40 keV. We conclude that Monte Carlo transport calculations accurately model the response of this well chamber. Further, applying the standard P{sub TP} correction factor for this well chamber is insufficient in accounting for the change in chamber response with air pressure for low-energy (<100 keV) photon and low-energy (<0.75 MeV){beta} sources.

Las Vegas Basin Seismic Response Project: Preliminary Results From Seismic Refraction Experiments, Las Vegas, NV.  

NASA Astrophysics Data System (ADS)

In May and September 2002, seismic refraction data were acquired in the Las Vegas basin. Located in the southern Basin and Range province, the cities of Las Vegas, North Las Vegas, and Henderson sit atop a fault-bounded basin with a depth of up to 5 km and basin dimensions of roughly 60 km wide (east-west) by 50 km in length (north-south). Previous isostatic gravity, seismic reflection, and aeromagnetic studies indicate that a series of sub-basins exist beneath the unconsolidated basin fill, with the deepest sub-basin occurring 5 km west of the fault block bounding the eastern edge of the basin (Frenchman Mountain). The basin is significantly deeper along its northern extremity, following the path of the fault block bounding the northern edge of the basin (Las Vegas Valley Shear Zone), and along the western edge of Frenchman Mountain. Recent, paleoseismic studies have indicated that faults in the Las Vegas region have the potential for an earthquake of M6.5 to 7.0. It is estimated that a M6.9 earthquake in the basin could produce about 11 billion dollars in damage and a significant number of deaths and/or injuries. In addition, an equivalent or larger event in the Death Valley fault zone, 150 km distance, would also be devastating to the metropolitan area of approximately 1.5 million residents. Therefore, it is essential to understand the seismic hazard posed to the Las Vegas region. This project is part of a larger collaborative effort to characterize the basin and its response to ground shaking. The University of Nevada, Las Vegas with assistance from the University of Texas at El Paso, students from UNLV and UTEP, volunteers from the community and several students from Centennial High school deployed 432 portable seismic recorders ("Texans") throughout the valley. Shot point locations were located at three quarries in the valley, one to the north, one to the east and one to the southwest. The profiles cross the Las Vegas Valley Shear zone as well as a prominent NW/SE trending step in the basin floor across which the basement drops from 2 to 4 km in depth. In addition, the profiles cross several Quaternary fault scarps, which have recently been identified as tectonic in origin. Preliminary analyses of the seismic refraction data indicate that the basin has an average P-wave velocity of 4.5 km/s and is in agreement with the estimated basin depths from isostatic gravity studies (2 to 5 km depth). Both tomographic inversion and forward modeling techniques are being used to analyze these data. These data will be used to produce a velocity model of the basin and image the basin/bedrock contact. In addition, these data will be integrated into a community model, which is being produced by the Las Vegas Basin Seismic Response working group to further assess the site response of the basin.

Self-reported responsiveness to direct-to-consumer drug advertising and medication use: results of a national survey  

PubMed Central

Background Direct-to-consumer (DTC) marketing of pharmaceuticals is controversial, yet effective. Little is known relating patterns of medication use to patient responsiveness to DTC. Methods We conducted a secondary analysis of data collected in national telephone survey on knowledge of and attitudes toward DTC advertisements. The survey of 1081 U.S. adults (response rate = 65%) was conducted by the Food and Drug Administration (FDA). Responsiveness to DTC was defined as an affirmative response to the item: "Has an advertisement for a prescription drug ever caused you to ask a doctor about a medical condition or illness of your own that you had not talked to a doctor about before?" Patients reported number of prescription and over-the-counter (OTC) medicines taken as well as demographic and personal health information. Results Of 771 respondents who met study criteria, 195 (25%) were responsive to DTC. Only 7% respondents taking no prescription were responsive, whereas 45% of respondents taking 5 or more prescription medications were responsive. This trend remained significant (p trend .0009) even when controlling for age, gender, race, educational attainment, income, self-reported health status, and whether respondents "liked" DTC advertising. There was no relationship between the number of OTC medications taken and the propensity to discuss health-related problems in response to DTC advertisements (p = .4). Conclusion There is a strong cross-sectional relationship between the number of prescription, but not OTC, drugs used and responsiveness to DTC advertising. Although this relationship could be explained by physician compliance with patient requests for medications, it is also plausible that DTC advertisements have a particular appeal to patients prone to taking multiple medications. Outpatients motivated to discuss medical conditions based on their exposure to DTC advertising may require a careful medication history to evaluate for therapeutic duplication or overmedication.

Family burden in inherited ichthyosis: creation of a specific questionnaire  

PubMed Central

Background The concept of individual burden, associated with disease, has been introduced recently to determine the “disability” caused by the pathology in the broadest sense of the word (psychological, social, economic, physical). Inherited ichthyosis belong to a large heterogeneous group of Mendelian Disorders of Cornification. Skin symptoms have a major impact on patients’ Quality of Life but little is known about the burden of the disease on the families of patients. Objectives To develop and validate a specific burden questionnaire for the families of patients affected by ichthyosis. Methods Two steps were required. First, the creation of the questionnaire which followed a strict methodological process involving a multidisciplinary team and families. Secondarily, the validation of the questionnaire, including the assessment of its reliability, external validity, reproducibility and sensitivity, was carried out on a population of patients affected by autosomal recessive congenital ichthyosis. A population of parents of patients affected by ichthyosis was enrolled to answer the new questionnaire in association with the Short Form Q12 questionnaire (SF-12) and a clinical severity score was filled for each patient. Results Ninety four families were interviewed to construct the verbatim in order to create the questionnaire and a cognitive debriefing was realized. The concept of burden could be structured around five components: “economic”, “daily life”, “familial and personal relationship”, “work”, and “psychological impact”. As a result, “Family Burden Ichthyosis” (FBI) reproducible questionnaire of 25 items was created. Forty two questionnaires were analyzable for psychometric validation. Reliability (Cronbach’s alpha coefficient?=?0.89), reflected the good homogeneity of the questionnaire. The correlation between mental dimensions of the SF-12 and the FBI questionnaire was statistically significant which confirmed the external validity. The mean FBI score was 71.7?±?18.8 and a significant difference in the FBI score was shown between two groups of severity underlining a good sensitivity of the questionnaire. Conclusions The internal and external validity of the “FBI” questionnaire was confirmed and it is correlated to the severity of ichtyosis. Ichthyoses, and other chronic pathologies, are difficult to assess by clinical or Quality of Life aspects alone as their impact can be multidimensional. “FBI” takes them all into consideration in order to explain every angle of the handicap generated.

Late radiation responses in man: current evaluation from results from Hiroshima and Nagasaki.  

PubMed

Among the late effects of exposure to the atomic bombings of Hiroshima and Nagasaki, none looms larger than radiation related malignancies. Indeed, the late effects of A-bomb radiation on mortality appear to be limited to an increase in malignant tumors. At present, it can be shown that cancers of the breast, colon, esophagus, lungs, stomach, thyroid, and urinary tract as well as leukemia and multiple myeloma increase in frequency with an increase in exposure. No significant relationship to radiation can as yet be established for malignant lymphoma, nor cancers of the rectum, pancreas or uterus. Radiation induced malignancies other than leukemia seem to develop proportionally to the natural cancer rate for the attained age. For specific age-at-death intervals, both relative and absolute risks tend to be higher for those of younger age at the time of bombing. Other late effects include radiation-related lenticular opacities, disturbances of growth among those survivors still growing at the time of exposure, and mental retardation and small head sizes among the in utero exposed. Chromosomal abnormalities too are more frequently encountered in the peripheral leukocytes of survivors, and this increase is functionally related to their exposure. Some uncertainty continues to surround both the quantity and quality of the radiation released by these two nuclear devices, particularly the Hiroshima bomb. A recent reassessment suggests that the gamma radiation estimates which have been used in the past may be too low at some distances and the neutron radiation estimates too high at all distances; moreover, the energies of the neutrons released now appear "softer" than previously conjectured. These uncertainties are not sufficiently large, however, to compromise the reality of the increased frequency of malignancy, but make estimates of the dose response, particularly in terms of gamma and neutron exposures, tentative.

The Comparative Validity of Interactive Multimedia Questionnaires to Paper-Administered Questionnaires for Beverage Intake and Physical Activity: Pilot Study  

PubMed Central

Background Brief, valid, and reliable dietary and physical activity assessment tools are needed, and interactive computerized assessments (ie, those with visual cues, pictures, sounds, and voiceovers) can reduce administration and scoring burdens commonly encountered with paper-based assessments. Objective The purpose of this pilot investigation was to evaluate the comparative validity and reliability of interactive multimedia (IMM) versions (ie, IMM-1 and IMM-2) compared to validated paper-administered (PP) versions of the beverage intake questionnaire (BEVQ-15) and Stanford Leisure-Time Activity Categorical Item (L-Cat); a secondary purpose was to evaluate results across two education attainment levels. Methods Adults 21 years or older (n=60) were recruited to complete three laboratory sessions, separated by three to seven days in a randomly assigned sequence, with the following assessments–demographic information, two IMM and one paper-based (PP) version of the BEVQ-15 and L-Cat, health literacy, and an IMM usability survey. Results Responses across beverage categories from the IMM-1 and PP versions (validity; r=.34-.98) and the IMM-1 and IMM-2 administrations (reliability; r=.61-.94) (all P<.001) were significantly correlated. Paired t tests revealed significant differences in sugar-sweetened beverage (SSB) grams and kcal (P=.02 and P=.01, respectively) and total beverage kcal (P=.03), on IMM-1 and IMM-2; however, comparative validity was demonstrated between IMM-2 and the PP version suggesting familiarization with the IMM tool may influence participant responses (mean differences: SSB 63 grams, SEM 87; P=.52; SSB 21 kcal, SEM 33; P=.48; total beverage 65 kcal, SEM 49; P=.19). Overall mean scores between the PP and both IMM versions of the L-Cat were different (both P<.001); however, responses on all versions were correlated (P<.001). Differences between education categories were noted at each L-Cat administration (IMM-1: P=.008; IMM-2: P=.001; PP: P=.002). Major and minor themes from user feedback suggest that the IMM questionnaires were easy to complete, and relevant to participants' typical beverage choices and physical activity habits. Conclusions In general, less educated participants consumed more total beverage and SSB energy, and reported less engagement in physical activity. The IMM BEVQ-15 appears to be a valid and reliable measure to assess habitual beverage intake, although software familiarization may increase response accuracy. The IMM-L-Cat can be considered reliable and may have permitted respondents to more freely disclose actual physical activity levels versus the paper-administered tool. Future larger-scale investigations are warranted to confirm these possibilities.

Toll-Like Receptor 2 Deficiency Results in Impaired Antibody Responses and Septic Shock during Borrelia hermsii Infection ?  

PubMed Central

Overwhelming bacteremia is a leading cause of death. To understand the mechanisms involved in protective antibody and pathological inflammatory responses during bacteremia, we have been studying the murine model of Borrelia hermsii infection. Toll-like receptor (TLR) signaling plays an important role in generating the rapid anti-B. hermsii antibody responses required for the resolution of bacteremia. Using NF-?B reporter assays, we found that B. hermsii activates TLR2 and TLR9. However, TLR2?/? TLR9?/? mice exhibited an impairment in anti-B. hermsii antibody responses similar to that of TLR2?/? mice. Moreover, the impairment in the antibody responses of TLR2?/? mice or TLR2?/? TLR9?/? mice coincides with an order-of-magnitude-higher bacteremia, and death results from septic shock, as evidenced by a dysregulated systemic cytokine response and characteristic organ pathology. Since TLR2 appears to be the major extracellular sensor stimulated by B. hermsii, we hypothesized that during elevated bacteremia the activation of intracellular sensors of bacteria triggers dysregulated inflammation in TLR2?/? mice. Indeed, blocking the internalization of B. hermsii prevented the induction of inflammatory cytokine responses in TLR2-deficient cells. Furthermore, we found that B. hermsii activates the cytoplasmic sensor nucleotide-binding oligomerization domain 2 (NOD2). Macrophages deficient in both TLR2 and NOD2 have impaired cytokine responses to B. hermsii compared to cells lacking TLR2 alone, and B. hermsii-infected TLR2?/? NOD2?/? mice exhibited improved survival compared to TLR2?/? mice. These data demonstrate that TLR2 is critical for protective immunity and suggest that, during heightened bacteremia, recognition of bacterial components by intracellular sensors can lead to pathological inflammatory responses.

The 2011 Tohoku-oki earthquake: Results from rapid response geophysical surveys  

NASA Astrophysics Data System (ADS)

The rupture zone of the 2011 Tohoku-oki earthquake extends to 500 km x 200 km along the Japan Trench, but earthquake, tsunami and geodetic data revealed that the co-seismic slips are centered at trench ward of the epicenter. Those data also showed that the large slips may reach close to the trench axis. However, seafloor and sub-seafloor deformation from the earthquake had not been known without having data from a geophysical survey in the large slip area. Before the earthquake, JAMSTEC had carried out active-source seismic surveys in 1999. Multi-narrow beam bathymetry data was also obtained along the seismic profile simultaneously. In order to investigate seafloor deformation by the 2011earthquake, we carried out a bathymetry and seismic surveys along the same profile immediately after the earthquake during the period from March 14 to 31, and compared the bathymetry data acquired before and after the 2011 earthquake. From this analysis, we detected considerable bathymetric deviation on the landward side of the trench, extending up to the trench axis and estimated that the seafloor on the landward side of the trench moved 50 m horizontally in the SE to ESE direction, and 10 m upward. This observation suggests that the plate coupled zone between earthquakes does extend at the shallowest part of the subduction zone, which is used to believe to be a stable sliding region. Following the March survey, we acquired eight 2D seismic profiles with spacing of 10 - 20 km at the north and south of the profile of the March cruise. Although the seismic images are varied from a profile to profile, a common character is a normal fault system extending from near the trench to further landward side in the overriding plate. We tentatively interpret that the normal fault system may reflect the co-seismic and post-seismic deformation of the overriding plate, as normal fault type earthquakes become predominant after the earthquake. Additional seismic surveys including high resolution 2D grid survey will be carried out in August and October. All of those data will be used for a site selection of a rapid response drilling which is proposed to drill at the toe of the trench where we detected the large co-seismic displacement by the differential bathymetric survey.

Analysis of fabrication results for 17 × 17 polymer arrayed waveguide grating multiplexers with flat spectral responses  

NASA Astrophysics Data System (ADS)

Based on transmission theory, a 17 × 17 polymer arrayed waveguide grating (AWG) multiplexer parameter optimization is performed, and the influence of the fabrication results on the transmission characteristics are analyzed. In this paper, we mainly discuss three of the main errors in the fabrication of polymer AWG devices. One is ?n1, which is caused by the tuning of the core refractive index n1, the second is ?b, which results from the rotating-coating of the core thickness b, and the other is the non-ideal core cross-section, which is caused by steam redissolution. The effects of the above fabrication errors on the transmission characteristics of the AWG device are investigated, and compensation techniques are proposed. By comparing the theoretical simulation and experimental results, the shift in the transmission spectrum is reduced by 0.028 nm, the 3 dB bandwidth is increased by about 0.036 nm, the insertion loss is reduced by about 3 dB for the central channel and 4.5 dB for the edge channels, and the crosstalk is reduced by 1.5 dB.

The Wisconsin Predicting Patients' Relapse questionnaire  

PubMed Central

Introduction: Relapse is the most common smoking cessation outcome. Accurate prediction of relapse likelihood could be an important clinical tool used to influence treatment selection or duration. The aim of this research was to develop a brief clinical relapse proneness questionnaire to be used with smokers interested in quitting in a clinical setting where time is at a premium. Methods: Diverse items assessing constructs shown in previous research to be related to relapse risk, such as nicotine dependence and self-efficacy, were evaluated to determine their independent contributions to relapse prediction. In an exploratory dataset, candidate items were assessed among smokers motivated to quit smoking who enrolled in one of three randomized controlled smoking cessation trials. A cross-validation dataset was used to compare the relative predictive power of the new instrument against the Fagerström Test for Nicotine Dependence (FTND) at 1-week, 8-week, and 6-month postquit assessments. Results: We selected seven items with relatively nonoverlapping content for the Wisconsin Predicting Patient's Relapse (WI-PREPARE) measure, a brief, seven-item questionnaire that taps physical dependence, environmental factors, and individual difference characteristics. Cross-validation analyses suggested that the WI-PREPARE demonstrated a stronger prediction of relapse at 1-week and 8-week postquit assessments than the FTND and comparable prediction to the FTND at a 6-month postquit assessment. Discussion: The WI-PREPARE is easy to score, suggests the nature of a patient's relapse risk, and predicts short- and medium-term relapse better than the FTND.

Validation of a maternal questionnaire on correlates of physical activity in preschool children  

PubMed Central

Background Valid measures of physical activity correlates in preschool children are lacking. This study aimed to assess the validity, factor structure and internal consistency of a maternal questionnaire on potential correlates of four-year-old children's physical activity. Methods The questionnaire was designed to measure the following constructs: child personal factors; parental support and self-efficacy for providing support; parental rules and restrictions; maternal attitudes and perceptions; maternal behaviour; barriers to physical activity; and the home and local environments. Two separate studies were conducted. Study I included 24 mothers of four-year-old children who completed the questionnaire then participated in a telephone interview covering similar items to the questionnaire. To assess validity, the agreement between interview and questionnaire responses was assessed using Cohen's kappa and percentage agreement. Study II involved 398 mothers of four-year-old children participating in the Southampton Women's Survey. In this study, principal components analysis was used to explore the factor structure of the questionnaire to aid future analyses with these data. The internal consistency of the factors identified was assessed using Cronbach's alpha. Results Kappa scores showed 30% of items to have moderate agreement or above, 23% to have fair agreement and 47% to have slight or poor agreement. However, 89% of items had fair agreement as assessed by percentage agreement (? 66%). Limited variation in responses to variables is likely to have contributed to some of the low kappa values. Six questions had a low kappa and low percentage agreement (defined as poor validity); these included questions from the child personal factors, maternal self-efficacy, rules and restrictions, and local environment domains. The principal components analysis identified eleven factors and found several variables to stand alone. Eight of the composite factors identified had acceptable internal consistency (? ? 0.60) and three fell just short of achieving this (0.60 > ? > 0.50). Conclusion Overall, this maternal questionnaire had reasonable validity and internal consistency for assessing potential correlates of physical activity in young children. With minor revision, this could be a useful tool for future research in this area. This, in turn, will aid the development of interventions to promote physical activity in this age group.

Initial results from the coupled magnetosphere ionosphere thermosphere model: magnetospheric and ionospheric responses  

NASA Astrophysics Data System (ADS)

The Center for Integrated Space Weather Modeling (CISM) is developing a simulation package of the coupled Sun-Earth system by connecting existing models within each region. The Coupled Magnetosphere Ionosphere Thermosphere (CMIT) model combines the Lyon-Fedder-Mobarry global magnetohydrodynamic (MHD) magnetospheric (LFM) model with the Thermosphere Ionosphere Nested Grid (TING) model. The LFM uses the ideal MHD equations to model the interaction between the magnetospheric plasma and the solar wind. It includes the magnetosphere-ionosphere interaction by requiring the conservation of current flowing between the magnetosphere and a two dimensional ionosphere. TING is a three dimensional code designed to simulate the thermosphere-ionosphere system by solving the mass, momentum, and thermodynamic energy equations for the global thermosphere and ionosphere. Normally, TING uses parameterized models to describe the magnetospheric input into the ionosphere. We begin this paper with a description of how the TING model is used to replace the simple two dimensional ionosphere within the LFM to produce the CISM CMIT Model. The results from the coupled model for a series of steady IMF conditions are compared with the results from the LFM to show that these models have been successfully combined. The problem of high cross polar cap potentials remains, but the structure of the magnetosphere is not dramatically altered by the coupling and the ionospheric conductances show a more realistic distribution driven by EUV radiation as well as a more clearly defined auroral oval.

Rapid Nitrogen Cycling Following Wet-Up Results from Heterotroph, then Nitrifier Response  

NASA Astrophysics Data System (ADS)

The first rainfall following the hot, dry summer in arid and semi-arid ecosystems, known as wet-up, results in large pulses of carbon dioxide and nitrous oxide, two radiatively important gases. Nitrous oxide in general, is produced by nitrifiers and denitrifiers. Using laboratory simulations of wet-up, we monitored soil pools of ammonium and nitrate, gross rates of nitrogen mineralization and nitrification, effluxes of carbon dioxide and nitrous oxide, and gene expression of archaeal and bacterial amoA, a functional gene for nitrification and nirK, a functional gene for denitrification. Results from a California annual grassland soil show significant increases in the ammonium pool within one hour of water addition followed by a significant increase in the nitrate pool within three hours of water addition. Gross nitrogen mineralization and gross nitrification were very high with nitrogen mineralization being highest within three hours of wet-up. Ammonia-oxidizers were most active at nine hours after water addition. Nitrous oxide emissions followed the same pattern as nitrifiers, suggesting nitrification may play an important role in nitrous oxide emissions during wet-up.

Extended coverage for preventive services for the elderly: response and results in a demonstration population.  

PubMed Central

OBJECTIVES. This study was undertaken to test the acceptability of preventive services under Medicare waivers to a community-dwelling population aged 65 and over and to examine the effect of such services on health. METHODS. Medicare beneficiaries and designated primary care providers were sampled, and beneficiaries were screened and surveyed. A total of 4195 individuals were then randomized into intervention or control groups. Those in the intervention group were offered free preventive visits (under waivers) to their physicians. A follow-up survey of the entire group was administered after completion of the intervention. RESULTS. Sixty-three percent of the intervention group made a preventive clinical visit, and about half of them a counseling visit. For men, being married and having a solo practitioner were positively associated with accepting the intervention services, while for women, having had a mammogram, having a confidant, having a high school education, and having a female practitioner were so associated. The intervention group showed a greater health benefit than did the control group and had a significantly lower death rate: 8.3% vs 11.1%. CONCLUSIONS: Older individuals will respond to preventive programs, and such services will result in modest health gains.

Corporate response to reproductive hazards in the workplace: Results of the Family, Work, and Health Survey  

SciTech Connect

As a part of a Family, Work, and Health Survey, we analyzed corporate practices regarding reproductive hazards in the chemical and electronics manufacturing industries in Massachusetts. Over half of the 198 firms surveyed had at least one of four designated reproductive hazards in use. Among these firms, 57% provided information on reproductive risks to employees. Nearly 20% of companies excluded certain classes of workers from substances, work areas, or occupations on the basis of reproductive health concerns. Another 13% offered voluntary transfers to workers concerned about reproductive risks. With one exception, all restrictions and transfers applied to women only--even when scientific evidence supports potential reproductive risk to both sexes. Analysis of corporate practices by industry type, and size, gender stratification, and unionization of the workforce was carried out. Results of the survey raise important public health concerns about corporate practices that may restrict women's job opportunities on the basis of reproductive status while underprotecting the health of male workers.

A Prosocial Scale for the Preschool Behaviour Questionnaire: Concurrent and Predictive Correlates  

Microsoft Academic Search

The Preschool Behaviour Questionnaire has been used widely to assess children's aggressive, anxious, and hyperactive behaviour. Items from the Prosocial Behaviour Questionnaire were added to create a prosocial scale. The resulting questionnaire was administered to teachers of three large samples of kindergarten children and shown to have three stable, orthogonal components disruptive (13 items): anxious (6 items); and prosocial (10

Parents' attitudes towards hepatitis B vaccination for their children. A survey comparing paper and web questionnaires, Sweden 2005  

PubMed Central

Background The World Health Organisation, WHO, recommends that most countries should vaccinate all children against hepatitis B. Sweden has chosen not to do so, but the issue is reassessed regularly. The objective of this survey was to assess knowledge and attitudes towards hepatitis B vaccine for children among parents living in Sweden, and to compare distribution of responses and response rate between parents answering a postal questionnaire and those responding via the Internet. Methods A population-based cross-sectional survey, where the sampling frame consisted of all parents to a child born 2002 living in Sweden. Two independent samples of 1001 parents in each sample were drawn. All parents were contacted by postal mail. The parents in the first sample were invited to participate by answering a paper questionnaire. The parents in the second sample were given an individual user name along with a password, and asked to log on to the Internet to answer an identical electronic questionnaire. Results A total of 1229 questionnaires were analysed. The overall response rate for paper questionnaires was 55%, and 15% for the web version. Knowledge of the disease hepatitis B was overall high (90%). A higher degree of knowledge was seen among parents with education beyond high school (p = 0.001). This group of parents also had a higher tendency to reply via the Internet (p = 0.001). The willingness to accept hepatitis B vaccine for their child was correlated to the acceptance of the present childhood vaccination programme (p = 0.001). Conclusion The results reveal a high level of knowledge of the disease and a positive attitude to having their children vaccinated. This study also displays that the conventional postal method of surveying still delivers a higher response rate than a web-based survey.

'How Poor Are You?' - A Comparison of Four Questionnaire Delivery Modes for Assessing Socio-Economic Position in Rural Zimbabwe  

PubMed Central

Background Assessing socio-economic position can be difficult, particularly in developing countries. Collection of socio-economic data usually relies on interviewer-administered questionnaires, but there is little research exploring how questionnaire delivery mode (QDM) influences reporting of these indicators. This paper reports on results of a trial of four QDMs, and the effect of mode on poverty reporting. Methods This trial was nested within a community-randomised trial of an adolescent reproductive health intervention conducted in rural Zimbabwe. Participants were randomly allocated to one of four QDMs (three different self-administered modes and one interviewer-administered mode); a subset was randomly selected to complete the questionnaire twice. Questions covered three socio-economic domains: i) ownership of sellable and fixed assets; ii) ability to afford essential items; and iii) food sufficiency. Statistical analyses assessed the association between QDM and reporting of poverty, and compared the extent of response agreement between questionnaire rounds. Results 96% (n?=?1483) of those eligible took part; 395 completed the questionnaire twice. Reported levels of poverty were high. Respondents using self-administered modes were more likely to report being unable to afford essential items and having insufficient food. Among those completing the questionnaire twice using different modes, higher levels of poverty and food insufficiency were reported when they completed the questionnaire using a self-administered mode. Conclusion These data suggest that QDM plays a significant role in how different socio-economic indicators are reported, and reminds us to consider the mode of collection when identifying indicators to determine socio-economic position.

Lecture Evaluation Questionnaire Items Desired by the Alumni of the Faculty  

NASA Astrophysics Data System (ADS)

Lecture evaluation questionnaires have been carried out to students because they are the suitable ways to improve the classes. Though the purpose of lecture evaluation questionnaires is to confirm whether it has fulfilled faculties' responsibility or not, we consider that our lectures should be evaluated from the three viewpoints, namely, by the students, the academic staffs and the society members. We proposed successfully the lecture evaluation questionnaire items desired by the society members that are alumni of our faculty.

Multi- and unisensory decoding of words and nonwords result in differential brain responses in dyslexic and nondyslexic adults.  

PubMed

The present functional magnetic resonance imaging (fMRI) study was designed, in order to investigate the neural substrates involved in the audiovisual processing of disyllabic German words and pseudowords. Twelve dyslexic and 13 nondyslexic adults performed a lexical decision task while stimuli were presented unimodally (either aurally or visually) or bimodally (audiovisually simultaneously). The behavioral data collected during the experiment evidenced more accurate processing for bimodally than for unimodally presented stimuli irrespective of group. Words were processed faster than pseudowords. Notably, no group differences have been found for either accuracy or for reaction times. With respect to brain responses, nondyslexic compared to dyslexic adults elicited stronger hemodynamic responses in the leftward supramarginal gyrus (SMG), as well as in the right hemispheric superior temporal sulcus (STS). Furthermore, dyslexic compared to nondyslexic adults showed reduced responses to only aurally presented signals and enhanced hemodynamic responses to audiovisual, as well as visual stimulation in the right anterior insula. Our behavioral results evidence that the two groups easily identified the two-syllabic proper nouns that we provided them with. Our fMRI results indicate that dyslexics show less neuronal involvement of heteromodal and extrasylvian regions, namely, the STS, SMG, and insula when decoding phonological information. We posit that dyslexic adults evidence deficient functioning of word processing, which could possibly be attributed to deficits in phoneme to grapheme mapping. This problem may be caused by impaired audiovisual processing in multimodal areas. PMID:21641022

Clinician views of referring people with negative symptoms to outcome research: a questionnaire survey.  

PubMed

This paper reports on a survey of mental health clinician views of including people with psychosis and negative symptoms in outcome research. A questionnaire was forwarded to clinicians (the majority of whom were mental health nurses) completing post-registration undergraduate and postgraduate degree courses in psychosocial interventions for psychosis. Fifty questionnaires were returned (a response rate of 84.7%). A total of 47% of respondents indicated that they might refrain from offering this group as potential participants to clinical trials. Thematic analysis suggests views that negative symptoms are not amenable to treatment inform such decisions. The results highlight the potential difficulties faced by researchers investigating new treatments for people with negative symptoms, and suggest further exploration of clinician views of referring this group to research and psychosocial treatments is warranted.

Relative validity and reproducibility of a French dietary history questionnaire  

PubMed Central

Background A self-administered dietary history questionnaire, especially developed for use in a large French prospective cohort study, was tested for accuracy of food intake measurement by comparing it to the average of 9–12 24-hour recalls. This questionnaire was structured according to the French meal pattern. An important feature of the questionnaire was the separation into a quantification part and qualification part. The first part quantifies consumption by frequency and portion sizes per food group or food item. The second part provides more detailed qualitative information on separate items within one food group. The total number of food items in the questionnaire was 238. Methods The questionnaire was administered twice to 119 study subjects, with an interval of approximately one year (1990–1991). During that year, 24-hour recalls were carried out monthly. Reproducibility and relative validity of the questionnaire were assessed. Results The correlation coefficients for reproducibility ranged from 0.40 to 0.74 for foods and from 0.54 to 0.75 for nutrients. The correlation coefficients for relative validity ranged from 0.10 to 0.71 for foods and from 0.29 to 0.81 for nutrients (adjustment for total energy and attenuation for nutrients). Percentage of subjects classified in the same or adjacent quintile by questionnaire as well as by 24-hour recall was on average 76% for foods and 72% for nutrients. Conclusions These data indicate that this questionnaire can be used to classify study subjects according to their food or nutrient intake over a one-year period, within a known degree of precision.

Diagnostic accuracy of pre-exercise screening questionnaire: emphasis on educational level and cognitive status.  

PubMed

The physical activity readiness questionnaire (PAR-Q) has been the most popular simple method of screening for people who intend to engage in exercise programs. Despite of the recommendations indicating that the instrument should be applied in the age range from 15 to 69 years, the questionnaire has been widely used in elderly people. The aim of this study was to assess the diagnostic accuracy of PAR-Q in elderly women with respect to absolute and relative contraindications to exercise and verify the influence of educational level and cognitive status. Eighty-nine subjects (61-89 years) participated in the study and went through clinical exams and exercise testing. The influence of educational status, age and cognitive state (Mini-Mental State Examination, MMSE) on the PAR-Q responses was analyzed by logistic regression. The occurrences of absolute and relative contraindications were respectively 9% and 22%. The Sensitivity and Specificity were 75.0% and 19.8% (absolute) and 77.8% and 19.7% (relative). The PAR-Q results were not influenced by low educational status; age, or cognitive state. In conclusion, although the usefulness and easy applicability of the PAR-Q's questions, the responses to the questionnaire led to a high number of false positive and false negative cases, suggesting that it would not be adequate as a pre-participation screening tool in elder samples.

Factors influencing response to Botulinum toxin type A in patients with idiopathic cervical dystonia: results from an international observational study  

PubMed Central

Objectives Real-life data on response to Botulinum toxin A (BoNT-A) in cervical dystonia (CD) are sparse. An expert group of neurologists was convened with the overall aim of developing a definition of treatment response, which could be applied in a non-interventional study of BoNT-A-treated subjects with CD. Design International, multicentre, prospective, observational study of a single injection cycle of BoNT-A as part of normal clinical practice. Setting 38 centres across Australia, Belgium, Czech Republic, France, Germany, The Netherlands, Portugal, Russia and the UK. Participants 404 adult subjects with idiopathic CD. Most subjects were women, aged 41–60?years and had previously received BoNT-A. Outcome measures Patients were classified as responders if they met all the following four criteria: magnitude of effect (?25% improvement Toronto Western Spasmodic Torticollis Rating Scale), duration of effect (?12-week interval between the BoNT-A injection day and subject-reported waning of treatment effect), tolerability (absence of severe related adverse event) and subject's positive Clinical Global Improvement (CGI). Results High rates of response were observed for magnitude of effect (73.6%), tolerability (97.5%) and subject's clinical global improvement (69.8%). The subjective duration of effect criterion was achieved by 49.3% of subjects; 28.6% of subjects achieved the responder definition. Factors most strongly associated with response were age (<40?years; OR 3.9, p<0.05) and absence of baseline head tremor (OR 1.5; not significant). Conclusions Three of four criteria were met by most patients. The proposed multidimensional definition of response appears to be practical for routine practice. Unrealistically high patient expectation and subjectivity may influence the perception of a quick waning of effect, but highlights that this aspect may be a hurdle to response in some patients.

Engineer Education Considered from Questionnaire by Graduates  

NASA Astrophysics Data System (ADS)

We carried out questionnaire survey about technical education for graduates residing in Oita prefecture. As a result, we understood that they want to attend technical educations also after graduation. But their duties are too busy, so they cannot attend. A lecture that they want is CAD, and they hope that the lecture is under five times and for holding on Saturday or weekday night, and the expense is equal to or less than 30,000 yen. We understood that the place that they want to attend is their old school. Although authors and persons concerned with school has been showing many information of engineer education in HP, about 80% of all graduates did not know it. In a free opinion, they say that engineer education is inevitable but personnel trainings or humanities as a person are also demanded.

Comparison of deferral rates using a computerized versus written blood donor questionnaire: a randomized, cross-over study [ISRCTN84429599  

PubMed Central

Background Self-administered computer-assisted blood donor screening strategies may elicit more accurate responses and improve the screening process. Methods Randomized crossover trial comparing responses to questions on a computerized hand-held tool (HealthQuiz, or HQ), to responses on the standard written instrument (Donor Health Assessment Questionnaire, or DHAQ). Randomly selected donors at 133 blood donation clinics in the area of Hamilton, Canada participated from 1995 to 1996. Donors were randomized to complete either the HQ or the DHAQ first, followed by the other instrument. In addition to responses of 'yes' and 'no' on both questionnaires, the HQ provided a response option of 'not sure'. The primary outcome was the number of additional donors deferred by the HQ. Results A total of 1239 donors participated. Seventy-one potential donors were deferred as a result of responses to the questionnaires; 56.3% (40/71) were deferred by the DHAQ, and an additional 43.7% (31/71) were deferred due to risks identified by the HQ but not by the DHAQ. Fourteen donors self-deferred; 11 indicated on the HQ that they should not donate blood on that day but did not use the confidential self-exclusion option on the DHAQ, and three used the self-exclusion option on the DHAQ but did not indicate that they should not donate blood on the HQ. The HQ identified a blood contact or risk factor for HIV/AIDS or sexually transmitted infection that was not identified by the DHAQ in 0.1% to 2.7% of donors. Conclusion A self-administered computerized questionnaire may increase risk reporting by blood donors.

Effects of response format on speech intelligibility in noise: Results obtained from open-set, closed-set, and delayed response tasks  

NASA Astrophysics Data System (ADS)

Many word recognition studies over the last 40 years have used forced-choice closed-set tasks, based on the assumption that closed-set and open-set tasks differ only in the level of chance performance. However, Sommers, Kirk, and Pisoni (1997) found that lexical competition and talker variability produce robust effects on performance only in open-set tasks, suggesting fundamental differences in the task demands and processing strategies between open- and closed-set tasks. In the present study, listeners were asked to recognize spoken words degraded by a bit-flipping algorithm in three response formats: open-set, closed-set ``before,'' and closed-set ``after.'' In the closed-set ``before'' condition, the six response alternatives were presented 1 s prior to the onset of the auditory signal. In the closed-set ``after'' condition, the response alternatives were presented 1 s after the auditory signal. Results revealed significant effects of lexical competition and talker variability only in the open-set task. These findings suggest that even a delay of 1 s is not adequate to induce the task demands observed in open-set word recognition tests. [Work supported by NIH.].

Mailed survey follow-ups--are postcard reminders more cost-effective than second questionnaires?  

PubMed

Finding cost-effective ways to increase response to mailed surveys is a concern for many nurse researchers. This study compared two follow-up methods: sending a second questionnaire packet versus sending a reminder postcard to those who did not respond to an initial mailing. Although the second questionnaire yielded a higher response than did the postcard, the cost per additional response was approximately 2 1/2 times higher for the questionnaire than for the postcard when the differential cost of the two mailings is considered.

Which is the most useful patient-reported outcome in femoroacetabular impingement? Test-retest reliability of six questionnaires.  

PubMed

BACKGROUND/AIMS: The most reliable patient-reported outcomes (PROs) for people with femoroacetabular impingement (FAI) is unknown because there have been no direct comparisons of questionnaires. Thus, the aim was to evaluate the test-retest reliability of six existing PROs in a single cohort of young active people with hip/groin pain consistent with a clinical diagnosis of FAI. METHODS: Young adults with clinical FAI completed six PRO questionnaires on two occasions, 1-2 weeks apart. The PROs were modified Harris Hip Score, Hip dysfunction and Osteoarthritis Score, Hip Outcome Score, Non-Arthritic Hip Score, International Hip Outcome Tool, Copenhagen Hip and Groin Outcome Score. RESULTS: 30 young adults (mean age 24 years, SD 4 years, range 18-30 years; 15 men) with stable symptoms participated. Intraclass correlation coefficient(3,1) values ranged from 0.73 to 0.93 (95% CI 0.38 to 0.98) indicating that most questionnaires reached minimal reliability benchmarks. Measurement error at the individual level was quite large for most questionnaires (minimal detectable change (MDC95) 12.4-35.6, 95% CI 8.7 to 54.0). In contrast, measurement error at the group level was quite small for most questionnaires (MDC95 2.2-7.3, 95% CI 1.6 to 11). CONCLUSIONS: The majority of the questionnaires were reliable and precise enough for use at the group level. Samples of only 23-30 individuals were required to achieve acceptable measurement variation at the group level. Further direct comparisons of these questionnaires are required to assess other measurement properties such as validity, responsiveness and meaningful change in young people with FAI. PMID:23687003

Bisphosphonate use and health history questionnaire.  

PubMed

The health history form is a rapid, time-honored method used by practitioners to assess a patient's medical history before treatment. Because of increased reports of bisphosphonate-related osteonecrosis of the jaws (BRONJ), we investigated the percentage of our patients taking oral bisphosphonates who actually reported taking the medication on our health history form. A questionnaire inquiring about bisphosphonate use was sent to 1,400 female patients who had undergone implant placement in the last five years. A total of 500 responses were received; of these, 112 reported they used bisphosphonates. We then reviewed the charts of the 112 patients to determine the percentage of patients who had included bisphosphonate use in their health history form. Only 35% of our patients who were using bisphosphonates had reported taking bisphosphonates on the health history form. With the difficulties in treating BRONJ, we strongly suggest including direct questions concerning bisphosphonate use in the medical history form so practitioners can identify the patient population that is at risk and can modify the treatment plan to avoid potentially disastrous clinical situations.

Translation and validation of the Danish version of the Patient Rated Wrist Evaluation questionnaire.  

PubMed

Abstract The need for validated outcome measures is increasing. The purpose is to translate and validate the Patient Rated Wrist Evaluation (PRWE) in Danish. Translation was done by an expert panel followed by evaluation of a lay panel and a field test on 10 patients. Sixty patients with wrist fractures were included. Both lay panel comments and field test revealed issues not dealt with by the expert panel, and a final version of the Danish PRWE was made. The validation process then continued and reliability results. were presented as Cronbach's alpha = 0.94, describing the homogeneity and the intraclass correlation coefficient = 0.88 and difference of mean = 5.7 (CI = 1.12-10.37, p = 0.017), describing the concordance of the results. Convergent validity at first and last control was for pain, 0.51 and 0.46, and physical mobility, 0.56 and 0.64, respectively, describing the correlation with a gold standard questionnaire. A minor floor effect was noticed, but not enough to indicate a lack of sensitivity of the PRWE. Effect size, the ability to measure sensitivity to change, was 0.62, also described as responsiveness. The translation resulted in a questionnaire that represents correct easy-understandable Danish. It is concluded that the modified Danish version is a valid questionnaire for patients with wrist fractures. PMID:23596992

Clinical COPD Questionnaire score (CCQ) and mortality  

PubMed Central

Introduction The Clinical COPD Questionnaire (CCQ) measures health status and can be used to assess health-related quality of life (HRQL). We investigated whether CCQ is also associated with mortality. Methods Some 1111 Swedish primary and secondary care chronic obstructive pulmonary disease (COPD) patients were randomly selected. Information from questionnaires and medical record review were obtained in 970 patients. The Swedish Board of Health and Welfare provided mortality data. Cox regression estimated survival, with adjustment for age, sex, heart disease, and lung function (for a subset with spirometry data, n = 530). Age and sex-standardized mortality ratios were calculated. Results Over 5 years, 220 patients (22.7%) died. Mortality risk was higher for mean CCQ ? 3 (37.8% died) compared with mean CCQ < 1 (11.4%), producing an adjusted hazard ratio (HR) (and 95% confidence interval [CI]) of 3.13 (1.98 to 4.95). After further adjustment for 1 second forced expiratory volume (expressed as percent of the European Community for Steel and Coal reference values ), the association remained (HR 2.94 [1.42 to 6.10]). The mortality risk was higher than in the general population, with standardized mortality ratio (and 95% CI) of 1.87 (1.18 to 2.80) with CCQ < 1, increasing to 6.05 (4.94 to 7.44) with CCQ ? 3. Conclusion CCQ is predictive of mortality in COPD patients. As HRQL and mortality are both important clinical endpoints, CCQ could be used to target interventions.

Brief Report: the Social Responsiveness Scale for Adults (SRS-A): initial results in a German cohort.  

PubMed

The Social Responsiveness Scale (SRS) is a tool for quantitative autism assessment in children and adolescents. The SRS-A addresses social responsiveness in adulthood. Reliability and validity using the German adaptation of the SRS-A was examined in 20 adults with Autism Spectrum Disorder (ASD), 62 with other mental disorders (CLIN) and 163 typically developing (TD) participants. Cronbach's alpha ranged from .71 (TD) to .89 (ASD). A SRS-A total score of 67 had a sensitivity of .85, and a specificity of .83 for ASD versus CLIN/TD. Correlations with established autism scales (ADOS, AQ, SCQ) were moderate to high (r = .25-.83). Results provide adequate preliminary support for the application of the SRS-A. PMID:22183423

A Comparison of a Postal Survey and Mixed-Mode Survey Using a Questionnaire on Patients' Experiences With Breast Care  

PubMed Central

Background The Internet is increasingly considered to be an efficient medium for assessing the quality of health care seen from the patients’ perspective. Potential benefits of Internet surveys such as time efficiency, reduced effort, and lower costs should be balanced against potential weaknesses such as low response rates and accessibility for only a subset of potential participants. Combining an Internet questionnaire with a traditional paper follow-up questionnaire (mixed-mode survey) can possibly compensate for these weaknesses and provide an alternative to a postal survey. Objective To examine whether there are differences between a mixed-mode survey and a postal survey in terms of respondent characteristics, response rate and time, quality of data, costs, and global ratings of health care or health care providers (general practitioner, hospital care in the diagnostic phase, surgeon, nurses, radiotherapy, chemotherapy, and hospital care in general). Methods Differences between the two surveys were examined in a sample of breast care patients using the Consumer Quality Index Breast Care questionnaire. We selected 800 breast care patients from the reimbursement files of Dutch health insurance companies. We asked 400 patients to fill out the questionnaire online followed by a paper reminder (mixed-mode survey) and 400 patients, matched by age and gender, received the questionnaire by mail only (postal survey). Both groups received three reminders. Results The respondents to the two surveys did not differ in age, gender, level of education, or self-reported physical and psychological health (all Ps > .05). In the postal survey, the questionnaires were returned 20 days earlier than in the mixed-mode survey (median 12 and 32 days, respectively; P < .001), whereas the response rate did not differ significantly (256/400, 64.0% versus 242/400, 60.5%, respectively; P = .30). The costs were lower for the mixed-mode survey (€2 per questionnaire). Moreover, there were fewer missing items (3.4% versus 4.4%, P = .002) and fewer invalid answers (3.2% versus 6.2%, P < .001) in the mixed-mode survey than in the postal survey. The answers of the two respondent groups on the global ratings did not differ. Within the mixed-mode survey, 52.9% (128/242) of the respondents filled out the questionnaire online. Respondents who filled out the questionnaire online were significantly younger (P < .001), were more often highly educated (P = .002), and reported better psychological health (P = .02) than respondents who filled out the paper questionnaire. Respondents to the paper questionnaire rated the nurses significantly more positively than respondents to the online questionnaire (score 9.2 versus 8.4, respectively; ?2 1 = 5.6). Conclusions Mixed-mode surveys are an alternative method to postal surveys that yield comparable response rates and groups of respondents, at lower costs. Moreover, quality of health care was not rated differently by respondents to the mixed-mode or postal survey. Researchers should consider using mixed-mode surveys instead of postal surveys, especially when investigating younger or more highly educated populations.

Long-term changes in cognitive bias and coping response as a result of chronic unpredictable stress during adolescence  

PubMed Central

Animals that experience adverse events in early life often have life-long changes to their physiology and behavior. Long-term effects of stress during early life have been studied extensively, but less attention has been given to the consequences of negative experiences solely during the adolescent phase. Adolescence is a particularly sensitive period of life when regulation of the glucocorticoid “stress” hormone response matures and specific regions in the brain undergo considerable change. Aversive experiences during this time might, therefore, be expected to generate long-term consequences for the adult phenotype. Here we investigated the long-term effects of exposure to chronic unpredictable stress during adolescence on adult decision-making, coping response, cognitive bias, and exploratory behavior in rats. Rats exposed to chronic unpredictable stress (e.g., isolation, crowding, cage tilt) were compared to control animals that were maintained in standard, predictable conditions throughout development. Unpredictable stress during adolescence resulted in a suite of long-term behavioral and cognitive changes including a negative cognitive bias [F(1, 12) = 5.000, P < 0.05], altered coping response [T(1, 14) = 2.216, P = 0.04], and accelerated decision-making [T(1, 14) = 3.245, P = 0.01]. Exposure to chronic stress during adolescence also caused a short-term increase in boldness behaviors; in a novel object test 15 days after the last stressor, animals exposed to chronic unpredictable stress had decreased latencies to leave a familiar shelter and approach a novel object [T(1, 14) = 2.240, P = 0.04; T(1, 14) = 2.419, P = 0.03, respectively]. The results showed that stress during adolescence has long-term impacts on behavior and cognition that affect the interpretation of ambiguous stimuli, behavioral response to adverse events, and how animals make decisions.

Questionnaires for eliciting evaluation data from users of interactive question answering  

SciTech Connect

Evaluating interactive question answering (QA) systems with real users can be challenging because traditional evaluation measures based on the relevance of items returned are difficult to employ since relevance judgments can be unstable in multi-user evaluations. The work reported in this paper evaluates, in distinguishing among a set of interactive QA systems, the effectiveness of three questionnaires: a Cognitive Workload Questionnaire (NASA TLX), and Task and System Questionnaires customized to a specific interactive QA application. These Questionnaires were evaluated with four systems, seven analysts, and eight scenarios during a 2-week workshop. Overall, results demonstrate that all three Questionnaires are effective at distinguishing among systems, with the Task Questionnaire being the most sensitive. Results also provide initial support for the validity and reliability of the Questionnaires.

[The ZZP Questionnaire. Reliability of a new resource utilization measure].  

PubMed

Data to determine the resource utilization of care recipients need to be reliable and the items that are measured need to be useful. In 2006, the Dutch Ministry of Health and Welfare has mandated all nursing homes and homes for the elderly to measure the Resource Utilization of all residents with the ZZP Questionnaire. Are the data resulting from this measurement reliable and is each of the 54 items of the ZZP Questionnaire useful? To answer this we tested the reliability of the data in a nursing home and a home for the elderly in two wards each. For 122 residents questionnaires were completed such that the inter- and intra-rater reliability of the answers could be assessed. Ten of the 54 items in the questionnaire showed insufficient inter rater reliability (<0.40) on the weighted Cohen kappa and another sixteen moderate (0.40 - 0.60). On the intra rater reliability test seven items had an insufficient kappa and another fifteen moderate. Besides, ten clusters of items could be formed with in-cluster Spearman correlation rates of .75 or higher. From the results of the reliability tests and the item intercorrelation rates we concluded that a substantial number of items needs to be improved and that in the ZZP Questionnaire 15 of the 54 items appear to be redundant on statistical grounds.

Examining the ecological validity of the Talent Development Environment Questionnaire.  

PubMed

It is clear that high class expertise and effective practice exists within many talent development environments across the world. However, there is also a general consensus that widespread evidence-based policy and practice is lacking. As such, it is crucial to develop solutions which can facilitate effective dissemination of knowledge and promotion of evidence-based talent development systems. While the Talent Development Environment Questionnaire (Martindale et al., 2010 ) provides a method through which this could be facilitated, its ecological validity has remained untested. As such, this study aimed to investigate the real world applicability of the questionnaire through discriminant function analysis. Athletes across ten distinct regional squads and academies were identified and separated into two broad levels, 'higher quality' (n = 48) and 'lower quality' (n = 51) environments, based on their process quality and productivity. Results revealed that the Talent Development Environment Questionnaire was able to discriminate with 77.8% accuracy. Furthermore, in addition to the questionnaire as a whole, two individual features, 'quality preparation' (P < 0.01) and 'understanding the athlete' (P < 0.01), were found to be significant discriminators. In conclusion, the results indicate robust structural properties and sound ecological validity, allowing the questionnaire to be used with more confidence in applied and research settings.

Acute pressure on the sciatic nerve results in rapid inhibition of the wide dynamic range neuronal response  

PubMed Central

Background Acute pressure on the sciatic nerve has recently been reported to provide rapid short-term relief of pain in patients with various pathologies. Wide dynamic range (WDR) neurons transmit nociceptive information from the dorsal horn to higher brain centers. In the present study, we examined the effect of a 2-min application of sciatic nerve pressure on WDR neuronal activity in anesthetized male Sprague–Dawley rats. Results Experiments were carried out on 41 male Sprague–Dawley albino rats weighing 160–280 grams. Dorsal horn WDR neurons were identified on the basis of characteristic responses to mechanical stimuli applied to the cutaneous receptive field. Acute pressure was applied for 2 min to the sciatic nerve using a small vascular clip. The responses of WDR neurons to three mechanical stimuli applied to the cutaneous receptive field were recorded before, and 2, 5 and 20 min after cessation of the 2-min pressure application on the sciatic nerve. Two-min pressure applied to the sciatic nerve caused rapid attenuation of the WDR response to pinching, pressure and brushing stimuli applied to the cutaneous receptive field. Maximal attenuation of the WDR response to pinching and pressure was noted 5 min after release of the 2-min pressure on the sciatic nerve. The mean firing rate decreased from 31.7±1.7 Hz to 13±1.4 Hz upon pinching (p < 0.001), from 31.2±2.3 Hz to 10.9±1.4 Hz (p < 0.001) when pressure was applied, and from 18.9±1.2 Hz to 7.6±1.1 Hz (p < 0.001) upon brushing. Thereafter, the mean firing rates gradually recovered. Conclusions Our results indicate that acute pressure applied to the sciatic nerve exerts a rapid inhibitory effect on the WDR response to both noxious and innocuous stimuli. Our results may partially explain the rapid analgesic effect of acute sciatic nerve pressure noted in clinical studies, and also suggest a new model for the study of pain.

Global 3-D imaging of mantle conductivity based on inversion of observatory C-responses—II. Data analysis and results  

NASA Astrophysics Data System (ADS)

The global 3-D electrical conductivity distribution in the mantle (in the depth range between 400 and 1600 km) is imaged by inverting C-responses estimated on a global net of geomagnetic observatories. Very long time-series (up to 51 years; 1957-2007) of hourly means of three components of the geomagnetic field from 281 geomagnetic observatories are collected and analysed. Special attention is given to data processing in order to obtain unbiased C-responses with trustworthy estimates of experimental errors in the period range from 2.9 to 104.2 d. After careful inspection of the obtained C-responses the data from 119 observatories are chosen for the further analysis. Squared coherency is used as a main quality indicator to detect (and then to exclude from consideration) observatories with a large noise-to-signal ratio. During this analysis we found that—along with the C-responses from high-latitude observatories (geomagnetic latitudes higher than 58°)—the C-responses from all low-latitude observatories (geomagnetic latitudes below 11°) also have very low squared coherencies, and thus cannot be used for global induction studies. We found that the C-responses from the selected 119 mid-latitude observatories show a huge variability both in real and imaginary parts, and we investigated to what extent the ocean effect can explain such a scatter. By performing the systematic model calculations we conclude that: (1) the variability due to the ocean effect is substantial, especially at shorter periods, and it is seen for periods up to 40 d or so; (2) the imaginary part of the C-responses is to a larger extent influenced by the oceans; (3) two types of anomalous C-response behaviour associated with the ocean effect can be distinguished; (4) to accurately reproduce the ocean effect a lateral resolution of 1°× 1° of the conductance distribution is needed, and (5) the ocean effect alone does not explain the whole variability of the observed C-responses. We also detected that part of the variability in the real part of the C-responses is due to the auroral effect. In addition we discovered that the auroral effect in the C-responses reveals strong longitudinal variability, at least in the Northern Hemisphere. Europe appears to be the region with smallest degree of distortion compared with North America and northern Asia. We found that the imaginary part of the C-responses is weakly affected by the auroral source, thus confirming the fact that in the considered period range the electromagnetic (EM) induction from the auroral electrojet is small. Assuming weak dependence of the auroral signals on the Earth's conductivity at considered periods, and longitudinal variability of the auroral effect, we developed a scheme to correct the experimental C-responses for this effect. With these developments and findings in mind we performed a number of regularized 3-D inversions of our experimental data in order to detect robust features in the recovered 3-D conductivity images. Although differing in details, all our 3-D inversions reveal a substantial level of lateral heterogeneity in the mantle at the depths between 410 and 1600 km. Conductivity values vary laterally by more than one order of magnitude between resistive and conductive regions. The maximum lateral variations of the conductivity have been detected in the layer at depths between 670 and 900 km. By comparing our global 3-D results with the results of independent global and semi-global 3-D conductivity studies, we conclude that 3-D conductivity mantle models produced so far are preliminary as different groups obtain disparate results, thus complicating quantitative comparison with seismic tomography or/and geodynamic models. In spite of this, our 3-D EM study and most other 3-D EM studies reveal at least two robust features: reduced conductivity beneath southern Europe and northern Africa, and enhanced conductivity in northeastern China.

Amifostine reduces side effects and improves complete response rate during radiotherapy: Results of a meta-analysis  

SciTech Connect

Purpose: To evaluate the efficacy of amifostine in diminishing radiotherapy side effects and whether or not it protects the tumor. Methods and Materials: We performed a systematic review and meta-analysis of 14 included randomized controlled trials, comprising 1451 patients, comparing the use of radiotherapy vs. radiotherapy plus amifostine for cancer treatment. Results: The use of amifostine significantly reduced the risk of developing mucositis (odds ratio [OR], 0.37; 95% confidence interval [CI], 0.29-0.48; p < 0.00001), esophagitis (OR, 0.38; CI, 0.26-0.54; p < 0.00001), acute xerostomia (OR, 0.24; CI, 0.15-0.36; p < 0.00001), late xerostomia (OR, 0.33; CI, 0.21-0.51; p < 0.00001), dysphagia (OR, 0.26; CI, 0.07-0.92; p 0.04), acute pneumonitis (OR, 0.15; CI, 0.07-0.31; p < 0.00001) and cystitis (OR, 0.17; CI, 0.09-0.32; p < 0.00001). There was no difference in overall response rate between the groups. However, complete response rate was superior for patients using amifostine (OR, 1.81; CI, 1.10-2.96; p = 0.02). Conclusions: This systematic review shows that amifostine significantly reduces the side effects of radiation therapy. The efficacy of radiotherapy was not itself affected by the use of this drug and patients receiving amifostine were able to achieve higher rates of complete response.

Cross-cultural adaptation of the work role functioning questionnaire to spanish spoken in Spain.  

PubMed

Purpose The Work Role Functioning Questionnaire (WRFQ) is a tool developed in the United States to measure work disability and assess the perceived impact of health problems on worker ability to perform jobs. We translated and adapted the WRFQ to Spanish spoken in Spain and assessed preservation of its psychometric properties. Methods Cross-cultural adaptation of the WRFQ was performed following a systematic 5-step procedure: (1) direct translation, (2) synthesis, (3) back-translation, (4) consolidation by an expert committee and (5) pre-test. Psychometric properties were evaluated by administering the questionnaire to 40 patients with different cultural levels and health problems. Applicability, usability, readability and integrity of the WRFQ were assessed, together with its validity and reliability. Results Questionnaire translation, back translation and consolidation were carried out without relevant difficulties. Idiomatic issues requiring reformulation were found in the instructions, response options and in 2 items. Participants appreciated the applicability, usability, readability and integrity of the questionnaire. The results indicated good face and content validity. Internal consistency was satisfactory for all subscales (Cronbach's alpha between 0.88 and 0.96), except for social demands (Cronbach's alpha = 0.56). Test-retest reliability showed good stability, with intraclass correlation coefficients between 0.77 and 0.93 for all subscales. Construct validity was considered preserved based on the comparison of median scores for each patient group and subscale. Conclusions Our results indicate the cross-cultural adaptation of the WRFQ to Spanish was satisfactory and preserved its psychometric properties, except for the subscale of social demands, whose internal consistency should be interpreted with caution.

Validation of a chronotype questionnaire including an amplitude dimension.  

PubMed

The aim of this paper was to validate a French version of the Chronotype Questionnaire (Ogi?ska, 2011, Pers. Individ. Dif. 50:1039-1043), which represents an interesting novelty in the psychometric assessment of chronotype, because it comprises not only an assessment of the morningness-eveningness (ME) dimension, but also a distinctness (DI) dimension (i.e., amplitude), which represents the range of diurnal variation. In study 1, we aimed to confirm the structure of the Chronotype Questionnaire, with two different samples, young adults (n = 338, mean ± SD = 18.70 ± 1.12 yrs, 244 men and 94 women) and old adults (n = 477, mean ± SD = 55.92 ± 11.9 yrs, 168 men and 310 women). The confirmatory factor analysis (CFA) indicated a poor fit in both samples as well as in the whole sample, which could be due to some inconsistencies in the original instrument, above all in the distinctness dimension. We therefore decided to revise the Chronotype Questionnaire, keeping the ME dimension, but refining the DI dimension. In study 2, with a new sample of 197 participants (mean ± SD = 22.71 ± 2.23 yrs, 105 men and 92 women), we examined the factor structure of the revised scale containing 18 items. The resulting questionnaire contained 16 items (i.e., 8 items on each scale), with item factor loadings higher than .45. In study 3, we aimed to confirm the factor structure of the instrument developed in study 2 as well as to examine its convergent validity, with a new sample of 158 participants (mean ± SD = 55.92 ± 11.9 yrs, 97 men and 61 women). Results of the CFA showed that a good fit of the model could be obtained with 16 items in the questionnaire. The new questionnaire derived from the original Chronotype Questionnaire was from now on called the Caen Chronotype Questionnaire (CCQ). Convergence validity was obtained with the Horne and Östberg questionnaire and the ME scale of the CCQ, showing a negative significant relationship (r = -.82). The CCQ showed promising psychometric qualities, and further research should aim to combine it with physiological variables. PMID:23510464

VALIDITATION OF A LIGHT QUESTIONNAIRE WITH REAL-LIFE PHOTOPIC ILLUMINANCE MEASUREMENTS: THE HARVARD LIGHT EXPOSURE ASSESSMENT QUESTIONNAIRE  

PubMed Central

Background Light exposure at night is now considered a probable carcinogen. To study the effects of light on chronic diseases like cancer, methods to measure light exposure in large observational studies are needed. We aimed to investigate the validity of self-reported current light exposure. Methods We developed a self-administered semiquantitative light questionnaire, the Harvard Light Exposure Assessment (H-LEA) questionnaire, and compared photopic scores derived from this questionnaire with actual photopic and circadian measures obtained from a real-life 7-day light meter application among 132 women (85 rotating night shift workers and 47 day workers) participating in the Nurses' Health Study II. Results After adjustment for age, BMI, collection day, and night work status, the overall partial Spearman correlation between self-report of light exposure and actual photopic light measurements was 0.72 (P<0.001; Kendall ? =0.57) and 0.73 (P<0.0001; Kendall ? =0.58) when correlating circadian light measurements. There were only minimal differences in accuracy of self-report of light exposure and photopic or circadian light measurement between day (r=0.77 and 0.78, respectively) and rotating night shift workers (r=0.68 and 0.69, respectively). Conclusions The results of this study provide evidence of the criterion validity of self-reported light exposure using the H-LEA questionnaire. Impact: This questionnaire is a practical method of assessing light exposure in large scale epidemiologic studies.

Measuring Presenteeism: Which Questionnaire to use in Physical Activity Research?  

PubMed

BACKGROUND: An emerging area of interest in workplace health is presenteeism; the measurable extent to which physical or psycho-social symptoms, conditions and disease adversely affect the work productivity of those who choose to remain at work. Given established links between presenteeism and health, and health and physical activity, presenteeism could be an important outcome in workplace physical activity research. This study provides a narrative review of questionnaires for use in such research. METHODS: Eight self-report measures of presenteeism were identified. Information regarding development, constructs measured and psychometric properties was extracted from relevant articles. RESULTS: Questionnaires were largely self-administered, had 4 to 44 items and recall periods ranging from one week to one year. Items were identified as assessing work performance, physical tolerance, psychological well-being and social or role functioning. Samples used to test questionnaires were predominantly American male employees, with an age range of 30-59 years. All instruments had undergone psychometric assessment, most commonly discriminant and construct validity. CONCLUSION: Based on instrument characteristics, the range of conceptual foci covered and acceptable measurement properties, the Health and Work Questionnaire, Work Ability Index and Work Limitations Questionnaire are suggested as most suitable for further exploring the relationship between physical activity and presenteeism.

Concentration-Response Function for Ozone and Daily Mortality: Results from Five Urban and Five Rural U.K. Populations  

PubMed Central

Background: Short-term exposure to ozone has been associated with increased daily mortality. The shape of the concentration–response relationship—and, in particular, if there is a threshold—is critical for estimating public health impacts. Objective: We investigated the concentration–response relationship between daily ozone and mortality in five urban and five rural areas in the United Kingdom from 1993 to 2006. Methods: We used Poisson regression, controlling for seasonality, temperature, and influenza, to investigate associations between daily maximum 8-hr ozone and daily all-cause mortality, assuming linear, linear-threshold, and spline models for all-year and season-specific periods. We examined sensitivity to adjustment for particles (urban areas only) and alternative temperature metrics. Results: In all-year analyses, we found clear evidence for a threshold in the concentration–response relationship between ozone and all-cause mortality in London at 65 µg/m3 [95% confidence interval (CI): 58, 83] but little evidence of a threshold in other urban or rural areas. Combined linear effect estimates for all-cause mortality were comparable for urban and rural areas: 0.48% (95% CI: 0.35, 0.60) and 0.58% (95% CI: 0.36, 0.81) per 10-µg/m3 increase in ozone concentrations, respectively. Seasonal analyses suggested thresholds in both urban and rural areas for effects of ozone during summer months. Conclusions: Our results suggest that health impacts should be estimated across the whole ambient range of ozone using both threshold and nonthreshold models, and models stratified by season. Evidence of a threshold effect in London but not in other study areas requires further investigation. The public health impacts of exposure to ozone in rural areas should not be overlooked.

Experimental and theoretical studies of spectral alteration in ultrasonic waves resulting from nonlinear elastic response in rock  

SciTech Connect

Experiments in rock show a large nonlinear elastic wave response, far greater than that of gases, liquids and most other solids. The large response is attributed to structural defects in rock including microcracks and grain boundaries. In the earth, a large nonlinear response may be responsible for significant spectral alteration at amplitudes and distances currently considered to be well within the linear elastic regime.

A solution is constructed for the problem of the overall elastic response of ideal (Gaussian or, equivalently, Neo-Hookean) rubber reinforced by a dilute isotropic distribution of rigid particles under arbitrarily large deformations. The derivation makes use of a novel iterative homogenization technique in finite elasticity that allows to construct exact solutions for the homogenization problem of two-phase nonlinear elastic composites with particulate microstructures. The solution is fully explicit for axisymmetric loading, but is otherwise given in terms of an Eikonal partial differential equation in two variables for general loading conditions. In the limit of small deformations, it reduces to the classical Einstein-Smallwood result for dilute suspensions of rigid spherical particles. The solution is further confronted to 3D finite-element simulations for the large-deformation response of a rubber block containing a single rigid spherical inclusion of infinitesimal size. The two results are found to be in good agreement for all loading conditions. We conclude this work by devising a closed-form approximation to the constructed solution which is remarkably accurate and — as elaborated in Part II — proves particularly amenable as a fundamental building block to generate approximate solutions for suspensions with finite concentration of particles.

Missing Data in a Long Food Frequency Questionnaire  

PubMed Central

Background Missing data are a common problem in nutritional epidemiology. Little is known of the characteristics of these missing data, which makes it difficult to conduct appropriate imputation. Methods We telephoned, at random, 20% of subjects (n = 2091) from the Adventist Health Study–2 cohort who had any of 80 key variables missing from a dietary questionnaire. We were able to obtain responses for 92% of the missing variables. Results We found a consistent excess of “zero” intakes in the filled-in data that were initially missing. However, for frequently consumed foods, most missing data were not zero, and these were usually not distinguishable from a random sample of nonzero data. Older, black, and less-well-educated subjects had more missing data. Missing data are more likely to be true zeroes in older subjects and those with more missing data. Zero imputation for missing data may create little bias except for more frequently consumed foods, in which case, zero imputation will be suboptimal if there is more than 5%–10% missing. Conclusions Although some missing data represent true zeroes, much of it does not, and data are usually not missing at random. Automatic imputation of zeroes for missing data will usually be incorrect, although there is a little bias unless the foods are frequently consumed. Certain identifiable subgroups have greater amounts of missing data, and require greater care in making imputations.

Episodic acidification of streams in the northeastern United States: Chemical and biological results of the episodic response project. Final report  

SciTech Connect

The document is the result of a cooperative research effort involving scientists from several agencies as part of the Aquatic Effects Research Program (AERP) of the U.S. Environmental Protection Agency (EPA). The Episodic Response Project (ERP) is an intensive study conducted at a limited number of sites, rather than an extensive regional study. The three areas targeted by the ERP are the Northern Appalachian Plateau of Pennsylvania, and the Adirondack and Catskill Mountains of New York. Each stream was monitored from fall 1988 through spring 1990, with continuous measurement of discharge and automated water sampling at fixed time intervals or at specified stage level changes. The water samples underwent chemical analysis for acid neutralizing capacity (ANC), pH, total dissolved aluminum, dissolved organic carbon (DOC), sulfate, nitrate, chloride, calcium, magnesium, potassium, and sodium. Furthermore, a subset of samples were analyzed for inorganic aluminum. Specific streams, participating institutions and cooperators, methods, and results are presented in the report.
