Responsiveness of the individual work performance questionnaire  

PubMed Central

Background Individual work performance is an important outcome measure in studies in the workplace. Nevertheless, its conceptualization and measurement has proven challenging. To overcome limitations of existing scales, the Individual Work Performance Questionnaire (IWPQ) was recently developed. The aim of the current study was to gain insight into the responsiveness of the IWPQ. Methods Data were used from the Be Active & Relax randomized controlled trial. The aim of the trial was to investigate the effectiveness of an intervention to stimulate physical activity and relaxation of office workers, on need for recovery. Individual work performance was a secondary outcome measure of the trial. In total, 39 hypotheses were formulated concerning correlations between changes on the IWPQ scales and changes on similar constructs (e.g., presenteeism) and distinct constructs (e.g., need for recovery) used in the trial. Results 260 Participants completed the IWPQ at both baseline and 12 months of follow-up. For the IWPQ scales, 23%, 15%, and 38%, respectively, of the hypotheses could be confirmed. In general, the correlations between change scores were weaker than expected. Nevertheless, at least 85% of the correlations were in the expected direction. Conclusions Based on results of the current study, no firm conclusions can be drawn about the responsiveness of the IWPQ. Several reasons may account for the weaker than expected correlations. Future research on the IWPQ’s responsiveness should be conducted, preferably in other populations and intervention studies, where greater changes over time can be expected.

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.

Attitudes to smoking on submarines: results of a questionnaire study.  

PubMed

An anonymous survey to assess the attitudes to smoking of men serving on two Trident Nuclear submarines was conducted by questionnaire. A total of 244 questionnaires were completed, representing 87% of the two crews. Thirty-two percent of respondents declared themselves to be smokers, 69% were nonsmokers, and of these, 31% were ex-smokers. Attitudes of all respondents to an enforced ban of smoking on submarines indicated that 55% felt that it would be justifiable, 46% felt that it would be unfair, 42% felt that it was uncalled for, 46% thought that it would be illegal, and 47% thought that a ban was about time. The separate opinions of smokers and nonsmokers were polarized, whereas the overall results indicate indifferent attitudes of crew members. Further research into the atmospheric effects of environmental tobacco smoke on a submarine is required. PMID:12125854

Advance telephone calls ahead of reminder questionnaires increase response rate in non-responders compared to questionnaire reminders only: The RECORD phone trial  

PubMed Central

Background Postal questionnaires are simple and economical for collecting outcome data for randomised controlled trials (RCTs) but are prone to non-response. In the RECORD trial (a large pragmatic publicly funded RCT in UK) non-responders were sent a reminder and another questionnaire at 1 year, of which 40% were returned. In subsequent years we investigated the effect of an advance telephone call to non-responders on responses rate to reminder questionnaires and the next questionnaire 4 months later. Methods Non-responders to annual questionnaires were randomised to receive a telephone call from the trial office ahead of the reminder questionnaire in addition to the usual reminder schedule (n?=?390) or to a control group that received the usual reminder schedule only (n?=?363). The primary outcome was response to the reminder questionnaire within 21 days; secondary outcomes were response to a questionnaire 4 months later; completeness of quality of life instruments; and the number of participants declining further follow-up. Results are presented as odds ratios from a logistic regression intention-to-treat (ITT) analysis and then percentage difference and 95% confidence intervals (CI) for both ITT and average treatment effect on the treated (ATT) analyses. Results The proportions that responded were 67.8% (265/390) in the intervention group compared to 62.5% (227/363) in the control group. The ITT estimate was a 5.4% increase (95% CI ?1.4 to 12.2). Four months later percentages responding were 51.8% (202) and 42.7% (155). The ITT estimate was a 9.1% increase (95% CI 2.0 to 16.2). In the intervention group 12.3% (48/390) of participants were not telephoned because questionnaires were returned before the scheduled telephone call. ATT estimates adjusting for this were 6.2% (95% CI ?1.6 to 14.0) and 10.4% (95% CI 2.2 to 18.5), respectively. Conclusions The telephone call resulted in a slight increase in response to the reminder questionnaire, however at 4 months later the proportion in the telephoned group responding was greater. This study suggests that pre-notification telephone calls may only be worthwhile if further questionnaires are to be sent out soon after reminder questionnaires.

Evaluation of the response of a questionnaire study by using the GIS and standard statistical methods.  

PubMed

This study is a part of a larger project Nr. NJ 6139-3 funded by the Grant Agency of the Czech Ministry of Health. The aim of the paper was to analyse the response rate using standard statistical methods and the Geographical Information System (GIS); to indicate differences in the response by sex, age, education, and employment; to determine the breakpoint for the collection of questionnaires according to which we can estimate the total response rate; to indicate whether the study sample was representative enough to generalize the project results. The additional aim of the paper was to collect those background literary sources dealing with the response rate as a methodological paradigm. The statistical and GIS analysis were based on comparison of the total population data (Census 2001), the study sample and the sample of the completed questionnaires data in the 23 districts of the city of Ostrava. The information from the data collection was derived from the date of receipt for each questionnaire. The literature sources were obtained from the Internet--in total 228 papers from the period since 1986 to the present have been checked. The main results of this study are: the GIS analysis was confirmed in all stages by standard statistical methods--it can therefore be used as a valid tool for quick orientation in data and for the comparison of a study sample with the general population; we did not find significant differences in the course of the collection of the questionnaires between sex, age, education, and the employment of respondents; it can be seen that the breakpoint according to which we can estimate the total response rate, is the 10th day after the questionnaires are distributed by post (75% of the questionnaires collected); our sample is representative enough from the geographical point of view.

A procedure for removing the effect of response bias errors from waterfowl hunter questionnaire responses  

USGS Publications Warehouse

Response bias errors are studied by comparing questionnaire responses from waterfowl hunters using four large public hunting areas with actual hunting data from these areas during two hunting seasons. To the extent that the data permit, the sources of the error in the responses were studied and the contribution of each type to the total error was measured. Response bias errors, including both prestige and memory bias, were found to be very large as compared to non-response and sampling errors. Good fits were obtained with the seasonal kill distribution of the actual hunting data and the negative binomial distribution and a good fit was obtained with the distribution of total season hunting activity and the semi-logarithmic curve. A comparison of the actual seasonal distributions with the questionnaire response distributions revealed that the prestige and memory bias errors are both positive. The comparisons also revealed the tendency for memory bias errors to occur at digit frequencies divisible by five and for prestige bias errors to occur at frequencies which are multiples of the legal daily bag limit. A graphical adjustment of the response distributions was carried out by developing a smooth curve from those frequency classes not included in the predictable biased frequency classes referred to above. Group averages were used in constructing the curve, as suggested by Ezekiel [1950]. The efficiency of the technique described for reducing response bias errors in hunter questionnaire responses on seasonal waterfowl kill is high in large samples. The graphical method is not as efficient in removing response bias errors in hunter questionnaire responses on seasonal hunting activity where an average of 60 percent was removed.

Responsiveness of the Korean Version of the Michigan Hand Outcomes Questionnaire after Carpal Tunnel Release  

PubMed Central

Background The Korean version of the Michigan Hand Outcomes Questionnaire (K-MHQ) was recently validated; however, the questionnaire's responsiveness as well as the degree to which the instrument is sensitive to change has not been thoroughly evaluated in a specific condition in Koreans. We evaluated the responsiveness of the K-MHQ in a homogenous cohort of patients with carpal tunnel syndrome (CTS) and we compared it with that of the Korean version of the Disability of the Arm, Shoulder, and Hand Questionnaire (K-DASH), which was found to have a large degree of responsiveness after carpal tunnel release for Korean patients with CTS. Methods Thirty-seven patients with CTS prospectively completed the K-MHQ and the K-DASH before and 6 months after surgery. The responsiveness statistics were assessed for both the K-MHQ and the K-DASH by using the standardized response mean (SRM), which was defined as the mean change of the original scores after surgery divided by the standard deviation of the change. Results All domains of the K-MHQ significantly improved after carpal tunnel release (p < 0.001). The SRM for all scales but one (the aesthetics scale) showed large responsiveness of ? 0.8. The aesthetics scale showed medium responsiveness of 0.6. The combined function/symptom scale of the K-DASH significantly improved after surgery (p < 0.001). The SRM of the K-DASH revealed large responsiveness of 0.9. Conclusions The K-MHQ was found to have a large degree of responsiveness after carpal tunnel release for Korean patients with CTS, which is comparable not only to the K-DASH, but also to the original version of the MHQ. The region-specific K-MHQ can be useful for outcomes research related to carpal tunnel surgery, especially for research comparing CTS with various other hand and wrist health conditions.

Does response on the PHQ-9 Depression Questionnaire predict subsequent suicide attempt or suicide death?  

PubMed

OBJECTIVE As use of standard depression questionnaires in clinical practice increases, clinicians will frequently encounter patients reporting thoughts of death or suicide. This study examined whether responses to the Patient Health Questionnaire for depression (PHQ-9) predict subsequent suicide attempt or suicide death. METHODS Electronic records from a large integrated health system were used to link PHQ-9 responses from outpatient visits to subsequent suicide attempts and suicide deaths. A total of 84,418 outpatients age ?13 completed 207,265 questionnaires between 2007 and 2011. Electronic medical records, insurance claims, and death certificate data documented 709 subsequent suicide attempts and 46 suicide deaths in this sample. RESULTS Cumulative risk of suicide attempt over one year increased from .4% among outpatients reporting thoughts of death or self-harm "not at all" to 4% among those reporting thoughts of death or self-harm "nearly every day." After adjustment for age, sex, treatment history, and overall depression severity, responses to item 9 of the PHQ-9 remained a strong predictor of suicide attempt. Cumulative risk of suicide death over one year increased from .03% among those reporting thoughts of death or self-harm ideation "not at all" to .3% among those reporting such thoughts "nearly every day." Response to item 9 remained a moderate predictor of subsequent suicide death after the same factor adjustments. CONCLUSIONS Response to item 9 of the PHQ-9 for depression identified outpatients at increased risk of suicide attempt or death. This excess risk emerged over several days and continued to grow for several months, indicating that suicidal ideation was an enduring vulnerability rather than a short-term crisis. PMID:24036589

Daily Diaries vs Retrospective Questionnaires to Assess Asthma Control and Therapeutic Responses in Asthma Clinical Trials  

PubMed Central

Background: Presently, there is insufficient information to compare the value of daily diaries vs retrospective questionnaires for assessing symptoms in relationship to asthma control in clinical trials. Daily symptom diaries are often burdensome to gather, incomplete, susceptible to fabrication, and of questionable reliability. There is also concern that retrospective symptom questionnaires may be subject to poor recall and may be insensitive. Methods: To compare these two methods of assessing symptoms reporting, we analyzed data collected during the Best Add-on Therapy Giving Effective Responses (BADGER) trial. During the trial, asthma control in 182 children aged 6 to 17 years was assessed in two ways: (1) by asthma control days (ACDs) determined by manually recorded daily diary symptom and rescue medication use scores and (2) by monthly retrospective report of symptoms embedded within the age-appropriate version of the Asthma Control Test (ACT). Correlations between ACDs and ACT scores were analyzed, and the sensitivity of each method for measuring asthma control and determining the differential response among the three BADGER treatments was evaluated. Results: Although validated using a 4-week recall period, ACT correlated better with daily diary information from the last 2 weeks of the 4-week recall (r = 0.46) than from the first 2 weeks (r = 0.34). In addition, clinically significant differential treatment responses were detected using ACDs but not ACT scores . Conclusions: The results of this study indicate that daily diaries used to determine ACDs can be a more sensitive tool than ACT for assessing differential treatment responses with respect to asthma control.

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.

Responsiveness of the Multiple Sclerosis International Quality of Life questionnaire to disability change: a longitudinal study  

PubMed Central

Background Responsiveness, defined as the ability to detect a meaningful change, is a core psychometric property of an instrument measuring quality of life (QoL) rarely reported in multiple sclerosis (MS) studies. Objective To assess the responsiveness of the Multiple Sclerosis International Quality of Life (MusiQoL) questionnaire to change in disability over 24 months, defined by change in the Expanded Disability Status Scale (EDSS) score. Methods Patients with MS were enrolled into a multicenter, longitudinal observational study. QoL was assessed using both the MusiQoL and the 36-Item Short-Form (SF-36) instruments at baseline and every 6 months thereafter up to month 24; neurological assessments, including EDSS score, were performed at each evaluation. Results The 24-month EDSS was available for 524 patients. In the 107 worsened patients, two specific dimensions of MusiQoL, the sentimental and sexual life and the relationships with health care system dimensions, and ‘physical’ scores of SF-36 showed responsiveness. Conclusions Whereas specific dimensions of MusiQoL identified EDSS changes, the MusiQoL index did not detect disability changes in worsened MS patients in a 24-month observational study. Future responsiveness validation studies should include longer follow-up and more representative samples.

Assessing Relapse in Multiple Sclerosis Questionnaire: Results of a Pilot Study  

PubMed Central

There is need for a brief but comprehensive objective assessment tool to help clinicians evaluate relapse symptoms in patients with multiple sclerosis (MS) and their impact on daily functioning, as well as response to treatment. The 2-part Assessing Relapse in Multiple Sclerosis (ARMS) questionnaire was developed to achieve these aims. Part 1 consists of 7 questions that evaluate relapse symptoms, impact on activities of daily living (ADL), overall functioning, and response to treatment for previous relapses. Part 2 consists of 7 questions that evaluate treatment response in terms of symptom relief, functioning, and tolerability. The ARMS questionnaire has been evaluated in 103 patients with MS. The most commonly reported relapse symptoms were numbness/tingling (67%), fatigue (58%), and leg/foot weakness (55%). Over half of patients reported that ADL or overall functioning were affected very much (47%) or severely (11%) by relapses. Prescribed treatments for relapses included intravenous and/or oral corticosteroids (87%) and adrenocorticotropic hormone (13%). Nearly half of patients reported that their symptoms were very much (33%) or completely resolved (16%) following treatment. The most commonly reported adverse events were sleep disturbance (45%), mood changes (33%), weight gain (29%), and increased appetite (26%). Systematic assessment of relapses and response to relapse treatment may help clinicians to optimize outcomes for MS patients.

Design methodology for a community response questionnaire on sonic boom exposure  

NASA Technical Reports Server (NTRS)

A preliminary draft questionnaire concerning community response to sonic booms was developed. Interviews were conducted in two communities that had experienced supersonic overflights of the SR-71 airplane for several years. Even though the overflights had ceased about 6 months prior to the interviews, people clearly remembered hearing sonic booms. A total of 22 people living in central Utah and 23 people living along Idaho/Washington state border took part in these interviews. The draft questionnaire was constantly modified during the study in order to evaluate different versions. Questions were developed which related to annoyance, startle, sleep disturbance, building vibration, and building damage. Based on the data collected, a proposed community response survey response instrument was developed for application in a full-scale sonic boom study.

Response set bias, internal consistency and construct validity of the Oswestry Low Back Pain Disability Questionnaire  

PubMed Central

Background: The Oswestry Low Back Pain Disability Questionnaire (ODQ) is a widely used 10-item paper and pencil measure of disability resulting from low back pain. However, few studies have assessed the psychometric properties of the instrument. This study evaluated the response set bias, the internal consistency, and the construct validity of the ODQ. Objectives: The original ODQ was compared to seven modified versions to examine whether a response set bias existed. The internal consistency of the ODQ was assessed using the Cronbach alpha. Finally, the relationship between scores on the ODQ and the Roland Morris Functional Disability Scal (RM) was examined. Methods: Seven modified versions of the ODQ were developed from the original. One of the eight versions was randomly allocated to 102 adult patients presenting with low lack pain. There was no attempt to select patients on the basis of pain intensity or prior treatment so as to maximize the range and diversity of low back pain sufferers. Results: Results suggest that the responses given on the eight versions of the ODQ are a function of content and not of the format in which the items are presented. The ODQ also has strong internal consisstency (alpha = 0.85) and is strongly correlated to the RM (r = .70, p = .0005). The ODQ is a significant predictor of the RM scores (T-9.45, p = .0005) and duration of symptoms (T = -2.17, p = .0325). Conclusion: The ODQ appears to possess stable psychometric properties. The use of more than one version provides practitioners with a means of repeatedly assessing the disability levels of patients suffering from low back pain over the course of treatment.

Responses to a questionnaire on networking between OIE Reference Laboratories and OIE Collaborating Centres.  

PubMed

Two separate questionnaires were distributed to 20 OIE Collaborating Centres and 160 OIE Reference Laboratories to assess the current status of networking and collaboration among OIE Reference Laboratories and between OIE Reference Laboratories and OIE Collaborating Centres. The questionnaire for the OIE Reference Laboratories contained 7 sections with questions on networking between laboratories, reporting of information, biosecurity quality control, and financing. Emphasis was placed in obtaining information on inter-laboratory relationships and exchange of expertise, training needs and sharing of data and information. The questionnaire for the OIE Collaborating Centres contained six sections with the emphasis on aspects related to awareness of services that can be provided, expertise that could be made available, sharing of information and the relationship with the national veterinary services of the countries concerned. The responses to the questionnaires were collated, categorised and statistically evaluated to allow for tentative inferences on the data provided. Valuable information emanated from the data identifying the current status of networking and indicating possible shortcomings that could be addressed to improve networking. PMID:18084932

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.

Surveillance of testicular microlithiasis?: Results of an UK based national questionnaire survey  

PubMed Central

Background The association of testicular microlithiasis with testicular tumour and the need for follow-up remain largely unclear. Methods We conducted a national questionnaire survey involving consultant BAUS members (BAUS is the official national organisation (like the AUA in USA) of the practising urologists in the UK and Ireland), to provide a snapshot of current attitudes towards investigation and surveillance of patients with testicular microlithiasis. Results Of the 464 questionnaires sent to the BAUS membership, 263(57%) were returned. 251 returns (12 were incomplete) were analysed, of whom 173(69%) do and 78(31%) do not follow-up testicular microlithiasis. Of the 173 who do follow-up, 119(69%) follow-up all patients while 54(31%) follow-up only a selected group of patients. 172 of 173 use ultra sound scan while 27(16%) check tumour makers. 10(6%) arrange ultrasound scan every six months, 151(88%) annually while 10(6%) at longer intervals. 66(38%) intend to follow-up these patients for life while, 80(47%) until 55 years of age and 26(15%) for up to 5 years. 173(68.9%) believe testicular microlithiasis is associated with CIS in < 1%, 53(21%) think it is between 1&10% while 7(3%) believe it is > 10%. 109(43%) believe those patients who develop a tumour, will have survival benefit with follow-up while 142(57%) do not. Interestingly, 66(38%) who follow-up these patients do not think there is a survival benefit. Conclusion There is significant variability in how patients with testicular microlithiasis are followed-up. However a majority of consultant urologists nationally, believe surveillance of this patient group confers no survival benefit. There is a clear need to clarify this issue in order to recommend a coherent surveillance policy.

Knowledge and Behaviour of Young People Concerning Fertility Risks - Results of a Questionnaire  

PubMed Central

Purpose: The aim of this study was, in the light of the increasing number of involuntarily childless couples, to investigate the state of knowledge of young people of fertile age about the risks for fertility disorders and their own risk behaviour. In addition, we wanted to check for a relationship between these aspects and the motives for wanting children, individual personality traits and psychological status. Materials and Methods: 498 women and men between the ages of 18 and 30 years participated in an anonymous survey. The sample consisted of 153 medical students, 190 students from other faculties and 155 vocational trainees. Their knowledge was tested by way of open questions on reproduction. The sum total from relevant life-style factors was used to estimate their risk-taking behaviour. Their psychic states were examined using the Health Questionnaire for Patients “Gesundheitsfragebogen für Patienten” PHQ-D, in addition the Leipzig Questionnaire on Motives for Wanting Children “Der Leipziger Fragebogen zu Kinderwunschmotiven” and the short version of the “Big Five Inventory” BFI-K were used. Results: The participants were aware of the risks for fertility disorders but did not always correctly assess their influence on fertility. Their knowledge about reproduction was rather low (on average 6.3 from 16 points). Medical students had a significantly higher state of knowledge and exhibited less risky behaviour as compared to the other two groups. Depressiveness and risky behaviour correlated positively and emotional aspects played the major role in attitudes towards having children. Risk behaviour was best predicted by the variables depressiveness, low level of knowledge and the feeling of being restricted in personal life by children. Discussion: Lack of knowledge on the topics fertility and reproduction could be a reason for risky behaviour and thus have a negative impact on lifestyle factors relating to fertility. Young people are aware of the risk factors that may affect fertility but do not always act accordingly. Primary prevention or, respectively, health promotion is thus necessary to prevent further increases in the number of infertile couples.

General public awareness of heart failure: results of questionnaire survey during Heart Failure Awareness Day 2011  

PubMed Central

Introduction General public views about heart failure (HF) alone and in comparison with other chronic conditions are largely unknown; thus we conducted this survey to evaluate general public awareness about HF and HF disease burden relative to common chronic disease. Material and methods This was a cross-sectional survey during European Heart Failure Awareness Day 2011. People visiting the stands and other activities in 12 Slovenian cities were invited to complete a 14-item questionnaire. Results The analysis included 850 subjects (age 56 ±15 years, 44% men, 55% completed secondary education or higher). Overall, 83% reported to have heard about HF, 58% knew someone with HF, and 35% believed that HF is a normal consequence of ageing. When compared to other chronic diseases, HF was perceived as less important than cancer, myocardial infarction, stroke and diabetes with only 6%, 12%, 7%, and 5% of subjects ranking HF as number 1 in terms of prevalence, cost, quality of life, and survival. A typical patient with HF symptoms was recognized by 30%, which was comparable to the description of myocardial ischemia (33%) and stroke (39%). Primary care physicians (53%) or specialists (52%) would be primary sources of information about HF. If experiencing HF, 83% would prefer their care to be focused on quality of life rather than on survival (14%). Conclusions Many participants reported to have heard about heart failure but the knowledge was poor and with several misbeliefs. Heart failure was perceived as less important than several other chronic diseases, where cancer appears as a main concern among the general public.

The Three-Factor Eating Questionnaire and BMI in adolescents: results from the Québec family study.  

PubMed

Eating behaviour traits are associated with body weight variations in adults. The Three-Factor Eating Questionnaire (TFEQ) measures cognitive restraint, disinhibition and hunger, as well as their corresponding subscales, e.g. rigid and flexible control. The TFEQ has not been widely used in adolescents to investigate eating behaviour traits associated with body weight. The aim of the present study was to assess whether eating behaviour traits were associated with BMI in male and female adolescents. Sixty adolescents (thirty females and thirty males; mean age 15.0 (sd 2.4) years) from the Québec Family Study completed the TFEQ and 3 d dietary records. There were no sex differences in the TFEQ scores. Rigid control, disinhibition and emotional susceptibility (to overeat) were positively related to BMI z-scores for the entire sample (r 0.3, P < 0.05). There was a positive relationship between BMI z-scores and rigid control (r 0.39, P < 0.05) in females, while BMI z-scores were positively related to emotional susceptibility (r 0.42, P < 0.02) and disinhibition (r 0.41, P < 0.03) in males. Adolescents characterised by both high disinhibition and high rigid control had significantly higher BMI z-scores than those by both low disinhibition and low rigid control. There were no significant differences in BMI z-scores between the flexible control categories. Dietary macronutrient content was not consistently related to eating behaviour traits. These results show that the eating behaviour traits of disinhibition and rigid control are independently related to BMI z-scores in this group of adolescents. PMID:20447324

Learning about medical student mistreatment from responses to the medical school graduation questionnaire.  

PubMed

Although evidence of medical student mistreatment has accumulated for more than 20 years, only recently have professional organizations like the Association of American Medical Colleges (AAMC) and the American Medical Association truly acknowledged it as an issue. Since 1991, the AAMC's annual Medical School Graduation Questionnaire (GQ) has included questions about mistreatment. Responses to the GQ have become the major source of evidence of the prevalence and types of mistreatment. This article reviews national mistreatment data, using responses to the GQ from 2000 through 2012; examines how students' experiences have changed over time; and highlights the implications of this information for the broader medical education system. The authors discuss what mistreatment is, including the changing definitions from the GQ; the prevalence, types, and sources of mistreatment; and evidence of students reporting incidents. In addition, they discuss next steps, including better defining mistreatment, specifically public humiliation and belittling, taking into account students' subjective evaluations; understanding and addressing the influence of institutional culture and what institutions can learn from current approaches at other institutions; and developing better systems to report and respond to reports of mistreatment. They conclude with a discussion of how mistreatment currently is conceptualized within the medical education system and the implications of that conceptualization for eradicating mistreatment in the future.

What Explains Usage of Mobile Physician-Rating Apps? Results From a Web-Based Questionnaire  

PubMed Central

Background Consumers are increasingly accessing health-related information via mobile devices. Recently, several apps to rate and locate physicians have been released in the United States and Germany. However, knowledge about what kinds of variables explain usage of mobile physician-rating apps is still lacking. Objective This study analyzes factors influencing the adoption of and willingness to pay for mobile physician-rating apps. A structural equation model was developed based on the Technology Acceptance Model and the literature on health-related information searches and usage of mobile apps. Relationships in the model were analyzed for moderating effects of physician-rating website (PRW) usage. Methods A total of 1006 randomly selected German patients who had visited a general practitioner at least once in the 3 months before the beginning of the survey were randomly selected and surveyed. A total of 958 usable questionnaires were analyzed by partial least squares path modeling and moderator analyses. Results The suggested model yielded a high model fit. We found that perceived ease of use (PEOU) of the Internet to gain health-related information, the sociodemographic variables age and gender, and the psychographic variables digital literacy, feelings about the Internet and other Web-based applications in general, patients’ value of health-related knowledgeability, as well as the information-seeking behavior variables regarding the amount of daily private Internet use for health-related information, frequency of using apps for health-related information in the past, and attitude toward PRWs significantly affected the adoption of mobile physician-rating apps. The sociodemographic variable age, but not gender, and the psychographic variables feelings about the Internet and other Web-based applications in general and patients’ value of health-related knowledgeability, but not digital literacy, were significant predictors of willingness to pay. Frequency of using apps for health-related information in the past and attitude toward PRWs, but not the amount of daily Internet use for health-related information, were significant predictors of willingness to pay. The perceived usefulness of the Internet to gain health-related information and the amount of daily Internet use in general did not have any significant effect on both of the endogenous variables. The moderation analysis with the group comparisons for users and nonusers of PRWs revealed that the attitude toward PRWs had significantly more impact on the adoption and willingness to pay for mobile physician-rating apps in the nonuser group. Conclusions Important variables that contribute to the adoption of a mobile physician-rating app and the willingness to pay for it were identified. The results of this study are important for researchers because they can provide important insights about the variables that influence the acceptance of apps that allow for ratings of physicians. They are also useful for creators of mobile physician-rating apps because they can help tailor mobile physician-rating apps to the consumers’ characteristics and needs.

Ride quality assessment. III - Questionnaire results of a second flight programme  

NASA Technical Reports Server (NTRS)

A questionnaire was completed by 861 passengers on regularly-scheduled flights of four commuter airlines. Four types of aircraft were involved. Questions assessed major demographic variables, attitudes toward flying, frequency of flying, experience of airsickness, and passenger perceptions of detailed aspects of the physical environment. Passengers also rated their overall comfort level and their willingness to fly again. Passengers perceive motion, noise, and seat factors as the primary determinants of their comfort. Rated comfort is strongly related to willingness to fly again. Incidence of airsickness was low. Sex differences in reactions to aspects of the environment were found.

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

Multiple sclerosis in the Faroe Islands. 7. Results of a case control questionnaire with multiple controls.  

PubMed

Detailed questionnaires were completed in 1978-79 by 23 of the 28 then known resident Faroese multiple sclerosis (MS) patients and 127 controls. These controls were divided into 69 Group A (patient sibs and other relatives), 37 Group B (matched neighbor controls, their spouses and sibs, plus patient's spouse), and 21 Group C (distant matched controls, spouses, relatives living where MS patients never resided and British troops were not encamped during the war). No differences between cases and controls were found for education, occupation, types of residence, bathing, sanitary or drinking facilities, and nature of house construction or heating. Detailed dietary histories, available for half the subjects, revealed no differences, cases versus controls, for four age periods between age 0 and 30 years, and for 16 specified foodstuffs. Animal exposures showed overall no consistent differences by location or type of animal. There was a tendency to greater exposure to British troops during the war for cases versus Groups A and B but this did not attain statistical significance. Vaccinations for smallpox, tetanus and diphtheria were less common in the MS; no difference was found for other vaccinations. Except for a relative deficit in the cases for rubella and (insignificantly) for measles, mumps and chicken pox, reported illnesses were equally common among all groups. Operations, hospitalizations and injuries did not differentiate the groups, nor did age at menarche for women. Neurologic symptoms were significantly more common in the cases than in the controls.

[What do cancer chemotherapy outpatients want?--results of a questionnaire survey].  

PubMed

We conducted a questionnaire survey to evaluate patients at the cancer chemotherapy center of the university of occupational and environmental health hospital from January to March 2006. Thirty-three (61.1%) and 5 (9.2%) of 54 patients wished to receive chemotherapy on an outpatient basis and as inpatients, respectively. Among the reasons for wishing to be treated as outpatients were the following: Keeping in touch with family, not wanting to be hospitalized, a desire to work, and the wish to continue hobbies, at 45.5 (15/33), 36.4 (12/33), 24.2 (8/33), and 24.2 (8/33), respectively. Twenty-four (44.4%) patients voiced concerns about chemotherapy at an outpatient clinic in terms of associated adverse events, feeling bad about causing trouble to their family, and the desire to have consultations at night or on holidays. Thirty-eight (70.4%) patients wished to have chemotherapy within 3 hours, and 42 (77.7%) of them requested improvements in the examinations, time, duration of chemotherapy, and the effect of chemotherapy. These findings indicate that a major part of patients wish to receive cancer chemotherapy at an outpatient clinic within 3 hours. However, they also have serious reservations about any associate adverse events. We therefore need to improve the overall environment for cancer chemotherapy patients in order to allow them to feel safe when undergoing such treatments. PMID:17108742

General practitioners' evaluation of community psychiatric services: responsiveness to change of the General Practitioner Experiences Questionnaire (GPEQ)  

PubMed Central

Background Instruments have been developed to assess professional views of the quality of care but have rarely been tested for responsiveness to change. The objective of this study was to test the responsiveness of the General Practitioner Experiences Questionnaire (GPEQ) for the measurement of Community Mental Health Centres in Norway. Methods National surveys were conducted in Norway in 2006 (n = 2,415) and 2008 (n = 2,209) to measure general practitioners' evaluation of community mental health centres. GPs evaluated the centres by means of a postal questionnaire, consisting of questions focused on centre quality and cooperation with GPs. As part of the national surveys 75 GPs in 2006 and 66 GPs in 2008 evaluated Hamar community mental health centre. Between the surveys, several quality improvement initiatives were implemented which were directed at cooperation with and guidance for GPs in Stange municipality, one of eight municipalities in Hamar centre catchment area. The main outcome measures were changes in GPEQ scores from 2006 to 2008 for GPs evaluating Hamar community mental health centre from Stange municipality, and changes in scores for GPs in the other seven municipalities and nationally which were assessed for statistical significance. Results GPs in Stange municipality rated Hamar community mental health centre significantly better on the guidance scale in 2008 than in 2006; on a 0-100 scale where 100 represents the best possible experiences the score was 26.5 in 2006 and 58.3 in 2008 (p < 0.001). Apart from one item about workforce situation, none of the other scales and items showed significant changes. The control group from the other seven municipalities gave significantly poorer rating for the emergency situation scale, the workforce situation scale and seven items in 2008 than in 2006. The national results showed small differences between 2006 and 2008, even though several scales and items were significantly different. A question about changes in centre performance over the last 2-3 years showed that 82% of GPs from Stange municipality reported that Hamar community mental health centre had improved, compared to only 36% from the other seven municipalities and 40% nationally which was statistically significant. Conclusions Following the implementation of an initiative designed to enhance service quality, the GPEQ identified expected changes in the guidance scale for the intervention group, indicating that the instrument is responsive to change. The worsening of services for GPs in the control group evaluating Hamar centre warrants further study.

[Research into actual conditions and preventive care in periodontal disease. Relationship between questionnaire results and periodontal disease in youth].  

PubMed

The purpose of this study was to determine the prevalence of periodontal disease and the relationship between the results of questionnaire concerning periodontal disease and the actual periodontal condition in youth. The examination was carried out in three parts. In the first part, a questionnaire was conducted on 3,886 junior and senior high school students (12 to 18 years of age) living in Kawagoe, Japan. The questionnaire was composed by of items concerning habits of oral hygiene, periodontal symptoms, understanding of periodontal disease and history of diagnosis by dentist of periodontal disease. Secondary, mass intraoral examination was carried out on all objects. The examination covered gingival inflammation, periodontal probing depth, calculus, dental plaque, dental caries and malalignment. Lastly, we examined the relationship between the results of periodontal examination and questionnaire with the original periodontal classification. The following results were obtained: 1. As an example of items in questionnaire, 83.1% brushed their teeth more than two times daily. The understanding of oral hygiene concerning dental caries was improved, but concerning periodontal disease was still poor. 2. The symptom most frequently reported was gingival bleeding during tooth brushing (18.4%). 3. The percentage of persons with periodontal disease (moderate gingival inflammation and periodontal pocket 4 mm or deeper) was of the highest frequency at 13 years old. The proportion of males increased with the advanced state of periodontal disease. 4. A significant correlation was found (chi 2-test: alpha less than 0.001) between advanced state of periodontal disease and a decrease in tooth brushing time per day. 5. A significant correlation was found between the advance of periodontal disease and gingival bleeding on tooth brushing (chi 2-test: alpha less than 0.001). Similarly, a correlation was found between the advance of periodontal disease and gingival swelling (chi 2-test: alpha less than 0.001). 6. A significant correlation was found (chi 2-test: alpha less than 0.001) between the advance of periodontal disease and aggravation of condition of dental plaque, calculus, dental caries and malalignment.

[Tick infestation and tick prophylaxis in dogs in the area of Berlin/Brandenburg--results of a questionnaire study].  

PubMed

Ticks can transmit different pathogens to humans and animals. Dogs are frequently exposed to tick infestation, which underscores the importance of tick control measures. The objective of this study was to examine the awareness of dog owners regarding tick infestation and tick prophylaxis by a questionnaire survey. During the period from March to December 2010 a total of 616 owners of 670 dogs completed the questionnaire. According to the questionnaire results, 92% of the dogs were previously infested by ticks; 31% of these showed a moderate tick infestation (1-2 ticks a month), almost one in ten dogs was infested by eight or more ticks a month. 17% of the dogs were examined for ticks by the respective owner not at all or only at irregular intervals, 61% of the dogs were examined at least once a day. A tick prophylaxis was performed in 469 dogs (71%). In 353 dogs (53%), registered pharmaceutical products with appropriate label claims were employed. Spot-on products were used most frequently (93%), followed by collars (5%) and sprays (1%).These products were not used as recommended in 56% of the dogs. For further 33% of the dogs, it was not possible to decide if the products were used correctly or not. According to the dog owner statements, tick borne diseases were diagnosed in approximately 2% of the dogs. Dog specific characters, such as coat length, size, age, and walking habits were significant factors influencing the frequency of tick infestation. In summary it can be concluded that nearly every dog in the area of Berlin/Brandenburg is infested by ticks. In the majority of cases the prophylactic and/or therapeutic measures to prevent infestation are not performed correctly. PMID:23367671

The ChQoL questionnaire: an Italian translation with preliminary psychometric results for female oncological patients  

PubMed Central

Background in Occidental languages, no widely accepted questionnaire is available which deals with health related quality of life from the specific point of view of Traditional Chinese Medicine (TCM). Some psychometric tools of this kind are available in Chinese. One of them is the Chinese Quality of Life questionnaire (ChQoL). It comprises 50 items, subdivided in 3 Domains and 13 Facets. The ChQoL was built from scratch on the basis of TCM theory. It is therefore specifically valuable for the TCM practitioner. This paper describes our translation into Italian of the ChQoL, its first application to Occidental oncological patients, and some of its psychometric properties. Methods a translation scheme, originally inspired by the TRAPD procedure, is developed. This scheme focuses on comprehensibility and clinical usefulness more than on linguistic issues alone. The translated questionnaire is tested on a sample of 203 consecutive female patients with breast cancer. Shapiro-Wilk normality tests, Fligner-Killeen median tests, exploratory Two-step Cluster Analysis, and Tukey's test for non-additivity are applied to study the outcomes. Results an Italian translation is proposed. It retains the TCM characteristics of the original ChQoL, it is intelligible to Occidental patients who have no previous knowledge of TCM, and it is useful for daily clinical practice. The score distribution is not Normal, and there are floor and ceiling effects. A Visual Analogue Scale is identified as a suitable choice. A 3-point Likert scale can also efficiently describe the data pattern. The original scales show non-additivity, but an Anscombe-Tukey transformation with ? = 1.5 recovers additivity at the Domain level. Additivity is enhanced if different ? are adopted for different Facets, except in one case. Conclusions the translated questionnaire can be adopted both as a filing system based on TCM and as a source of outcomes for clinical trials. A Visual Analogue Scale is recommended, but a simpler 3-point Likert scale also suitably fits data. When estimating missing data, and when grouping items within Domain in order to build a summary Domain index, an Anscombe-Tukey transformation should be applied to the raw scores.

Government/industry response to questionnaire on space mechanisms/tribology technology needs  

NASA Technical Reports Server (NTRS)

President Bush has proposed that the U.S. undertake an ambitious mission of manned and robotic exploration of the solar system. This mission will require advanced mechanical moving components, such as bearings, gears, seals, lubricants, etc. There has been concern in the NASA community that the current technology level in these mechanical component/tribology areas may not be adequate to meet the goals of such a mission. To attempt to answer this, NASA-Lewis has sent out a questionnaire to government and industry workers (who have been involved in space mechanism research, design, and implementation) to ask their opinion if the current space mechanisms technology (mechanical components/tribology) is adequate to meet future NASA Missions needs and goals. If they deemed that the technology base inadequate, they were asked to specify the areas of greatest need. The unedited remarks of those who responded to the survey are presented.

[Is there a link between the mercury release of amalgam fillings and the results of psychological questionnaires?].  

PubMed

Amalgam as a dental filling material shows excellent material property. It is fast, easy and economical to implement. Evidence for the release of mercury (Hg) from amalgam fillings was given in a number of studies. Mercury release from amalgam dental fillings is often claimed to be a possible cause of unspecific chronic symptoms such as chronic fatigue, headache and migraine. The present study explored relationships between the mercury release from amalgam fillings and the results of psychological questionnaires. The urine of 126 men and women in the age range of 16 to 76 years was examined. 45 participants did not present any amalgam restorations. The mercury released into the urine was measured by using cold-vapour AAS. The results of the study show that chronic mercury exposure, in the low concentration range, is not linked with chronic subjective symptoms. PMID:20052827

[Assessing Desire for Suicide: First Results on Psychometric Properties of the German Version of the Interpersonal Needs Questionnaire (INQ)].  

PubMed

Objectives: The Interpersonal Needs Questionnaire (INQ) assesses desire for suicide according to the Interpersonal Theory of Suicide. Psychometric properties of the German version of the INQ are investigated. Methods: The INQ was applied in a sample of 281 undergraduate students to investigate dimensionality, reliability and validity. Results: The 2-factorial structure of the original version was confirmed for the German version of the INQ in this sample. The subscales "Perceived Burdensomeness" (??=?0.88) and "Thwarted Belongingness" (??=?0.83) show very good internal consistencies. Both subscales show medium range correlations with depressiveness. There are significantly higher levels of "Perceived Burdensomeness" and "Thwarted Belongingness" in participants with current suicidal ideation or prior suicidal or self-injuring behaviour. Conclusion: These findings show that the German version of the INQ has good psychometric properties. Further research is needed to replicate these findings in clinical samples, and to test the utility of the INQ in predicting and preventing suicidal behaviour in patients at risk. PMID:23925932

Interactive voice response and web-based questionnaires for population-based infectious disease reporting.  

PubMed

The authors aimed to evaluate the web and an Interactive Voice Response (IVR) phone service as vehicles in population-based infectious disease surveillance. Fourteen thousand subjects were randomly selected from the Swedish population register and asked to prospectively report all respiratory tract infections, including Influenza-like Illness (ILI-clinical symptoms indicative of influenza but no laboratory confirmation), immediately as they occurred during a 36-week period starting October 2007. Participants were classified as belonging to the web or IVR group based on their choice of technology for initial registration. In all, 1,297 individuals registered via IVR while 2,044 chose the web. The latter were more often young and well-educated than those registered via IVR. Overall, 52% of the participants reported at least one infection episode. The risk of an infectious disease report was 14% (95% CI: 6, 22%) higher in the web group than in the IVR group. For ILI the excess was 27% (95% CI: 11, 47%). After adjustments for socio-demographic factors, statistically non-significant excesses of 1 and 8% remained, indicating trivial differences potentially attributable to the two reporting techniques. With attention to confounding, it should be possible to combine the web and IVR for simple reporting of infectious disease symptoms. PMID:20596884

[Quality of life in German nursing homes - results of a survey using the EQ-5D questionnaire].  

PubMed

In the course of reformation of the health-care system the impact of measuring the quality of life steadily rises. The current study reports the disease-comprehensive quality of life of the elderly who live in nursing homes and compares these results with the reference value of the German population. Furthermore, the results from the different nursing homes are compared with one another in order to prove the direct influence of the nursing home itself on the subjective quality of life of the habitants. The survey was conducted with the generic questionnaire EQ-5D which is an approved index-instrument for health-related quality of life measurement and has been translated into 102 languages so far. In total 342 persons from 8 different nursing homes took part in the survey, at least 25 persons from each nursing home. On the one hand the results show interesting divergences in the quality of life level between habitants and the German population. Differences of at least 2- up to 10-fold values have been proved. For example, there was a discrepancy in the fields of problems related to the habitant's sex, which was not documented in the study of German population. On the other hand high discrepancies when comparing the nursing homes among each other could be proved, although the age structure as well as the distribution between the sexes in at least 7 nursing homes was identical. So it seems that a direct impact of the nursing home on the quality of life of the habitants could be shown. The present study raises many new questions which implicate the need for further surveys. These findings may have a proximate effect on the future health-care system, which will have to involve age-based health-care provision as well as innovative concepts of caring. PMID:21072751

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

Results from the translation and adaptation of the Iranian Short-Form McGill Pain Questionnaire (I-SF-MPQ): preliminary evidence of its reliability, construct validity and sensitivity in an Iranian pain population  

PubMed Central

Background The Short Form McGill Pain Questionnaire (SF-MPQ) is one of the most widely used instruments to assess pain. The aim of this study was to translate and culturally adapt the questionnaire for Farsi (the official language of Iran) speakers in order to test its reliability and sensitivity. Methods We followed Guillemin's guidelines for cross-cultural adaption of health-related measures, which include forward-backward translations, expert committee meetings, and face validity testing in a pilot group. Subsequently, the questionnaire was administered to a sample of 100 diverse chronic pain patients attending a tertiary pain and rehabilitation clinic. In order to evaluate test-retest reliability, patients completed the questionnaire in the morning and early evening of their first visit. Finally, patients were asked to complete the questionnaire for the third time after completing a standardized treatment protocol three weeks later. Intraclass correlation coefficient (ICC) was used to evaluate reliability. We used principle component analysis to assess construct validity. Results Ninety-two subjects completed the questionnaire both in the morning and in the evening of the first visit (test-retest reliability), and after three weeks (sensitivity to change). Eight patients who did not finish treatment protocol were excluded from the study. Internal consistency was found by Cronbach's alpha to be 0.951, 0.832 and 0.840 for sensory, affective and total scores respectively. ICC resulted in 0.906 for sensory, 0.712 for affective and 0.912 for total pain score. Item to subscale score correlations supported the convergent validity of each item to its hypothesized subscale. Correlations were observed to range from r2 = 0.202 to r2 = 0.739. Sensitivity or responsiveness was evaluated by pair t-test, which exhibited a significant difference between pre- and post-treatment scores (p < 0.001). Conclusion The results of this study indicate that the Iranian version of the SF-MPQ is a reliable questionnaire and responsive to changes in the subscale and total pain scores in Persian chronic pain patients over time.

Lung cancer health care needs assessment: patients' and informal carers' responses to a national mail questionnaire survey.  

PubMed

The objective of this study was to describe patients' and informal carers' perceptions of care received and services offered following a diagnosis of primary lung cancer. We prepared a prospective, national, mail questionnaire survey of 466 patients with a diagnosis of primary lung cancer and a lay carer of their choice. The setting was 24 randomly chosen hospitals throughout the UK, from a range of urban (n = 11) and rural settings (n = 13). The majority (76%/159) of responders were recipients of care from cancer units. Two hundred and nine patients (45%) with primary lung cancer and 70 (15%) lay carers completed questionnaires. The main results that we found were that key areas of unmet need were most apparent during periods away from acute service sectors, with as few as 40% of patients reporting having received as much help as they needed from community services. The greatest onus of care for patients fell to lay carers, but only 29% of patients identified their lay carers as having needs in relation to their illness. Where patients received all their diagnostic tests in one hospital they were significantly more likely to wait less time between first seeing their general practitioner (GP) and being told their diagnosis (P = 0.0001) than patients who had to attend more than one hospital during their diagnostic work-up period. Fifty per cent of patients reported experiencing some degree of breathlessness even at rest, but only 15% reported having received any advice on living with it. Less than a quarter (23%) of hospital consultants identified anxiety as a key problem for patients with lung cancer, but 66% of patients identified it as such. Hospital staff largely overlook the needs of informal carers, who derive support from a small, mainly community oriented group of professionals, but accessing help is problematic and is dependent on local resources and a need to be proactive. Our conclusions are that developments in service provision for patients with lung cancer and their informal carers need to focus on six key areas: development of strategies to encourage patients to present earlier to their GP; ongoing evaluation of rapid diagnostic clinics; development and evaluation of a lung cancer care coordinator role; evaluation of innovations in delivery of nursing care in the community; development of local guidelines to facilitate equitable access to palliative care and social services; and evaluation of supportive strategies targeted at lay carers.

A Reliable, Valid and Responsive Questionnaire to Score the Impact of Knee Complaints on Work Following Total Knee Arthroplasty: The WORQ.  

PubMed

The Work, Osteoarthritis or joint-Replacement Questionnaire (WORQ) was developed to assess physical difficulty experienced in work before or following total knee arthroplasty (TKA). Thirteen questions were designed. The WORQ was tested for internal consistency by factor analysis, internal reliability (Crohnbach's ?), and construct validity. A test-retest reproducibility was performed for analyzing standard error of measurement (SEM agreement), reliability (ICC) and smallest detectable change (SDC) in individuals and groups. Lastly responsiveness (standardized response means [SRM]), floor and ceiling effects and interpretability (minimal important change [MIC]) were analyzed. It is shown that the WORQ is a reliable, valid and responsive questionnaire that can be used to evaluate the impact of knee complaints following TKA on patients' ability to work. PMID:24581898

Management practices and use of anthelmintics on dairy cattle farms in The Netherlands: results of a questionnaire survey.  

PubMed

In December 1996, a questionnaire about farm management and parasite control measures in calves was sent to 956 randomly chosen dairy cattle farmers in The Netherlands. Another 150 farmers in the vicinity of Deventer who had vaccinated their calves in 1995 against lungworm were approached with the same questions. Our object was to investigate the consequences on worm control of the withdrawal of the lungworm vaccine from the market for reasons of possible BSE contamination of the vaccine. OF the returned questionnaires, 411 (43%) of the 'at random' group and 89 (59.3%) of the 'Deventer' group were valid. The most important data with regard to the farms of the 'at random' group (41) were: mean area 31.6 ha, mean number of calves 23, heifers 23 and milking cows 53. Sheep (mean 37) were present on 18.3% of the farms. With regard to management: 74.5% of the farmers turned the calves in their first year onto pasture, 25.5% kept them indoors. The average time on pasture was ca. 5 months. Rational grazing was practise on 81.4% of the farms, on 18.6% calves were set stocked. The first pasture of the calves was mown before turn-out on 72.9% of the farms. On 48.2% of these farms, calves were always moved to mown pastures. With regard to treatments: 33.8% of the farmers vaccinated their calves against lungworm in the years 1993, 1994 and 1995. Despite the withdrawal of the vaccine from the market in 1996, 7.2% of the farmers vaccinated their calves as recommended, with two doses, and 13.1% with a single dose. At turn-out, 41.5% of the farmers gave the calves a preventive anthelmintic treatment. Of these treatments, 66.9% were sustained of pulse release long acting device. During the grazing season, 36.6% of the farmers treated their calves. After housing 50.3% of the farmers gave a treatment. Signs of lungworm infection were noticed on 18.6% of the farms. Of the 'Deventer' group (89 farmers), 96.6% turned the calves out, Of these farmers, 86.0% had used the lungworm vaccine in 1995. In 1996, 52.7% of the farmers had vaccinated the calves:36.5% with a single dose and 16.2% with the double dose. Of the 35 farmers who did not vaccinate in 1996, 62.9% gave a preventive treatment at turn-out. Clinical signs of lungworm infection were not observed on the 12 farms which vaccinated the calves twice. On 11% of the farms which vaccinated once and on 14% of the farms which did not vaccinate, signs of lungworm infection were observed. It is concluded that more than 80% of Dutch dairy cattle farmers take appropriate measures to control gastrointestinal nematode and lungworm infections in calves in their first grazing season by grazing on aftermath, rotational grazing on mown pastures combined or not with preventive anthelmintic treatments. However, combinations of aftermath grazing and preventive treatment occurred on 30% of the farms. This may be overprotective and may prevent sufficient build up of immunity, causing worm problems at a later age. The withdrawal of the lungworm vaccine from the market did not cause a rise in lungworm problems. Some farmers did vaccinate, despite the withdrawal. The majority used other preventive treatment measures, mainly the application of long acting boli. PMID:9703617

Validity, reliability, and responsiveness of a new shortVisual Simplified Respiratory Questionnaire (VSRQ©) for health-related quality of life assessment in chronic obstructive pulmonary disease  

PubMed Central

The Visual Simplified Respiratory Questionnaire (VSRQ) was designed to assess health-related quality of life (HRQoL) in patients with chronic obstructive pulmonary disease (COPD). It contains eight items: dyspnea, anxiety, depressed mood, sleep, energy, daily activities, social activities and sexual life. Psychometric properties were assessed during a clinical trial that evaluated the impact of tiotropium on HRQoL of COPD patients. These included the determination of structure, internal consistency reliability, concurrent validity with the St George’s Respiratory Questionnaire (SGRQ), test – retest reliability, clinical validity and responsiveness to change over two weeks. Minimal important difference (MID) was calculated; cumulative response curves (CRC) were based on the dyspnea item. Psychometric analyses showed that VSRQ structure was unidimensional. The questionnaire demonstrated good internal consistency reliability (Cronbach’s alpha = 0.84), good concurrent validity with SGRQ (Spearman = ?0.70) and clinical validity, good test-retest reproducibility (ICC = 0.77), and satisfactory responsiveness (standardized response mean = 0.57; Guyatt’s statistic = 0.63). MID was 3.4; CRC median value of the ‘minimally improved’ patients was 3.5. In conclusion, VSRQ brevity and satisfactory psychometric properties make it a good candidate for large studies to assess HRQoL in COPD patients. Further validation is needed to extend its use in clinical practice.

Pooling dietary data using questionnaires with open-ended and predefined responses: implications for comparing mean intake or estimating odds ratios.  

PubMed

In the current era of diet-gene analyses, large sample sizes are required to uncover the etiology of complex diseases. As such, consortia form and often combine available data. Food frequency questionnaires, which commonly use 2 different types of responses about the frequency of intake (predefined responses and open-ended responses), may be pooled to achieve the desired sample size. The common practice is to categorize open-ended responses into the predefined response categories. A problem arises when the predefined categories are noncontiguous: possible open-ended responses may fall in gaps between the predefined categories. Using simulated data modeled from frequency of intake among 1,664 controls in a lung cancer case-control study at The University of Texas M. D. Anderson Cancer Center (Houston, Texas, 2000-2005), the authors describe the effect of different categories of open-ended responses that fall in between noncontiguous, predefined response sets on estimates of the mean difference in intake and the odds ratios. A significant inflation of false positives appears when comparing mean differences of intake, while the bias in estimating odds ratios may be acceptably small. Therefore, if pooling data cannot be restricted to the same type of response, inferences should focus on odds ratio estimation to minimize bias. PMID:20139126

Randomised controlled comparison of the Health Survey Short Form (SF12) and the Graded Chronic Pain Scale (GCPS) in telephone interviews versus self-administered questionnaires. Are the results equivalent?  

Microsoft Academic Search

BACKGROUND: The most commonly used survey methods are self-administered questionnaires, telephone interviews, and a mixture of both. But until now evidence out of randomised controlled trials as to whether patient responses differ depending on the survey mode is lacking. Therefore this study assessed whether patient responses to surveys depend on the mode of survey administration. The comparison was between mailed,

[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. Factor loadings, discriminations and difficulties of the indicators could be regarded as good, with the exception of 2 items. These results indicate the factorial validity of the FEPS in patients with alcohol dependence. PMID:23446826

Psychological impact of human papillomavirus testing in women with borderline or mildly dyskaryotic cervical smear test results: cross sectional questionnaire study  

PubMed Central

Objective To describe the psychological impact on women of being tested for human papillomavirus (HPV) when smear test results are borderline or mildly dyskaryotic. Design Cross sectional questionnaire study. Setting Two centres participating in an English pilot study of HPV testing in women with borderline or mildly dyskaryotic smear test results. Participants Women receiving borderline or mildly dyskaryotic smear test results tested for HPV and found to be HPV positive (n = 536) or HPV negative (n = 331); and women not tested for HPV with borderline or mildly dyskaryotic smear results (n = 143) or normal smear results (n = 366). Main outcome measures State anxiety, distress, and concern about test result, assessed within four weeks of receipt of results. Results Women with borderline or mildly dyskaryotic smear results who were HPV positive were more anxious, distressed, and concerned than the other three groups. Three variables independently predicted anxiety in HPV positive women: younger age (? = -0.11, P = 0.03), higher perceived risk of cervical cancer (? = 0.17, P < 0.001), and reporting that they did not understand the meaning of test results (? = 0.17, P = 0.001). Testing HPV negative was not reassuring: among women with abnormal smear test results, those who were HPV negative were no less anxious than those who were not tested for HPV. Conclusions Informing women more effectively about the meaning of borderline or mildly dyskaryotic smear test results and HPV status, in particular about the absolute risks of cervical cancer and the prevalence of HPV infection, may avoid some anxiety for those who are HPV positive while achieving some reassurance for those who test HPV negative.

Treatment planning and delivery of involved field radiotherapy in advanced Hodgkin's disease: results from a questionnaire-based audit for the UK Stanford V regimen vs ABVD clinical trial quality assurance programme (ISRCTN 64141244).  

PubMed

This questionnaire forms the basis of the quality assurance (QA) programme for the UK randomized Phase III study of the Stanford V regimen versus ABVD for treatment of advanced Hodgkin's disease to assess differences between participating centres in treatment planning and delivery of involved-field radiotherapy for Hodgkin's lymphoma The questionnaire, which was circulated amongst 42 participating centres, consisted of seven sections: target volume definition and dose prescription; critical structures; patient positioning and irradiation techniques; planning; dose calculation; verification; and future developments The results are based on 25 responses. One-third plan using CT alone, one-third use solely the simulator and the rest individualize, depending on disease site. Eleven centres determine a dose distribution for each patient. Technique depends on disease site and whether CT or simulator planning is employed. Most departments apply isocentric techniques and use immobilization and customized shielding. In vivo dosimetry is performed in 7 centres and treatment verification occurs in 24 hospitals. In conclusion, the planning and delivery of treatment for lymphoma patients varies across the country. Conventional planning is still widespread but most centres are moving to CT-based planning and virtual simulation with extended use of immobilization, customized shielding and compensation.

Individual differences in satiety response to carbohydrate and fat. Predictions from the Three Factor Eating Questionnaire (TFEQ).  

PubMed

A high carbohydrate/low fat diet is recommended for reduced risk of overeating, but it is not clear whether satiety responses to carbohydrate and fat differ between individuals. The objective of this study was to determine how women with either a low or a high tendency to overeat (TFEQ-disinhibition) and with either a low or a high tendency to restrict intake (TFEQ-restraint) respond to fat and carbohydrate consumed at breakfast. Sixty-four healthy-weight women preselected for high and low TFEQ scores of restraint and disinhibition were enrolled for the study. They came to the laboratory on two separate days to consume breakfast; on one day the principle energy source was fat and on the other day carbohydrate. Satiety responses were determined by ratings of hunger and fullness for 2 h after breakfast, and intake at a mid-morning snack test. Those scoring high on the TFEQ-disinhibition scale consumed more energy at the snack test than those with low TFEQ-disinhibition, but this was only following the high carbohydrate breakfast. The TFEQ-restraint scale did not independently predict food intake or interact with the TFEQ-disinhibition related overeating. In normal-weight females the tendency to overeat may be related to insensitivity to the satiating effects of carbohydrate. PMID:21219950

"Would you accept having your DNA profile inserted in the National Forensic DNA database? Why?" Results of a questionnaire applied in Portugal.  

PubMed

The creation and expansion of forensic DNA databases might involve potential threats to the protection of a range of human rights. At the same time, such databases have social benefits. Based on data collected through an online questionnaire applied to 628 individuals in Portugal, this paper aims to analyze the citizens' willingness to donate voluntarily a sample for profiling and inclusion in the National Forensic DNA Database and the views underpinning such a decision. Nearly one-quarter of the respondents would indicate 'no', and this negative response increased significantly with age and education. The overriding willingness to accept the inclusion of the individual genetic profile indicates an acknowledgement of the investigative potential of forensic DNA technologies and a relegation of civil liberties and human rights to the background, owing to the perceived benefits of protecting both society and the individual from crime. This rationale is mostly expressed by the idea that all citizens should contribute to the expansion of the National Forensic DNA Database for reasons that range from the more abstract assumption that donating a sample for profiling would be helpful in fighting crime to the more concrete suggestion that everyone (criminals and non-criminals) should be in the database. The concerns with the risks of accepting the donation of a sample for genetic profiling and inclusion in the National Forensic DNA Database are mostly related to lack of control and insufficient or unclear regulations concerning safeguarding individuals' data and supervising the access and uses of genetic data. By providing an empirically-grounded understanding of the attitudes regarding willingness to donate voluntary a sample for profiling and inclusion in a National Forensic DNA Database, this study also considers the citizens' perceived benefits and risks of operating forensic DNA databases. These collective views might be useful for the formation of international common ethical standards for the development and governance of DNA databases in a framework in which the citizens' perspectives are taken into consideration.

Reliability, validity and responsiveness of the French version of the questionnaire Quick Disability of the Arm, Shoulder and Hand in shoulder disorders.  

PubMed

We assessed the reliability, validity and responsiveness of the French short version of the scale Disability of the Arm, Shoulder and Hand-Disability/Symptom (F-QuickDASH-D/S) in patients with shoulder disorders. We extracted QuickDASH item responses from the responses to the full-length DASH questionnaire completed by 153 patients. In addition to collecting demographic and clinical data, subjective assessment of activities of daily living (ADL), active range of motion (ROM), and measurement of abduction strength (strength) were recorded by use of the Constant scale. Cronbach's alpha coefficient was 0.89. The intraclass correlation coefficient was 0.94, which suggested excellent test-retest reliability. Correlation of the F-QuickDASH-D/S score with scores for F-DASH-D/S (r=0.96), handicap (r=0.79), ADL (r=-0.73), pain during activities (r=0.63), strength (r=-0.58), pain at rest (r=0.57) and ROM (r=-0.51) indicated good construct validity. Factor analysis identified 2 factors accounting for 59.1% of the variance. The responsiveness of F-QuickDASH-D/S was excellent, with standardized response mean and effect size values of 1.09 and 1.23, respectively. The F-QuickDASH-D/S has good reliability, construct validity and responsiveness. The strong correlation of its score with the full-length DASH-D/S scale score suggests that the QuickDASH-D/S could be the preferred scale because it is easier to use. PMID:18436467

Paper to Electronic Questionnaires: Effects on Structured Questionnaire Forms  

NASA Technical Reports Server (NTRS)

With the use of computers, paper questionnaires are being replaced by electronic questionnaires. The formats of traditional paper questionnaires have been found to effect a subject's rating. Consequently, the transition from paper to electronic format can subtly change results. The research presented begins to determine how electronic questionnaire formats change subjective ratings. For formats where subjects used a flow chart to arrive at their rating, starting at the worst and middle ratings of the flow charts were the most accurate but subjects took slightly more time to arrive at their answers. Except for the electronic paper format, starting at the worst rating was the most preferred. The paper and electronic paper versions had the worst accuracy. Therefore, for flowchart type of questionnaires, flowcharts should start at the worst rating and work their way up to better ratings.

A comparison of results from dynamic-response field tests  

NASA Astrophysics Data System (ADS)

The dynamic response of Howden's 330-kW horizontal-axis wind turbine (HAWT) and the Northern Power Systems 100-kW North Wind 100 HAWT has been measured. The Howden machine incorporates a 26-m-diameter, upwind, three-bladed, wood/epoxy rotor that operates at 42 rpm and is a rigid-hub design. The North Wind 100 rotor has a diameter of 17.8 m, is upwind, two-bladed, and constructed of fiberglass, and has a teetered hub. The Northern Power turbine's blades are fully pitchable, while the Howden machine uses pitchable blade tips. This paper will present the results from each of these test programs in an effort to compare the dynamic response of each turbine. The analysis will focus on rotor bending loads in terms of both time domain and frequency response. The FLAP code will be used to explore sensitivity to teeter stiffness and natural frequency placement to provide a better understanding of the differences in behavior caused by configuration alone. The results are presented in the form of normalized azimuth-averaged plots of the deterministic loads, and spectral density plots of the stochastic responses. This presentation of the results will contrast major response differences due to design configurations.

Conversion of Questionnaire Data  

SciTech Connect

During the survey, respondents are asked to provide qualitative answers (well, adequate, needs improvement) on how well material control and accountability (MC&A) functions are being performed. These responses can be used to develop failure probabilities for basic events performed during routine operation of the MC&A systems. The failure frequencies for individual events may be used to estimate total system effectiveness using a fault tree in a probabilistic risk analysis (PRA). Numeric risk values are required for the PRA fault tree calculations that are performed to evaluate system effectiveness. So, the performance ratings in the questionnaire must be converted to relative risk values for all of the basic MC&A tasks performed in the facility. If a specific material protection, control, and accountability (MPC&A) task is being performed at the 'perfect' level, the task is considered to have a near zero risk of failure. If the task is performed at a less than perfect level, the deficiency in performance represents some risk of failure for the event. As the degree of deficiency in performance increases, the risk of failure increases. If a task that should be performed is not being performed, that task is in a state of failure. The failure probabilities of all basic events contribute to the total system risk. Conversion of questionnaire MPC&A system performance data to numeric values is a separate function from the process of completing the questionnaire. When specific questions in the questionnaire are answered, the focus is on correctly assessing and reporting, in an adjectival manner, the actual performance of the related MC&A function. Prior to conversion, consideration should not be given to the numeric value that will be assigned during the conversion process. In the conversion process, adjectival responses to questions on system performance are quantified based on a log normal scale typically used in human error analysis (see A.D. Swain and H.E. Guttmann, 'Handbook of Human Reliability Analysis with Emphasis on Nuclear Power Plant Applications,' NUREG/CR-1278). This conversion produces the basic event risk of failure values required for the fault tree calculations. The fault tree is a deductive logic structure that corresponds to the operational nuclear MC&A system at a nuclear facility. The conventional Delphi process is a time-honored approach commonly used in the risk assessment field to extract numerical values for the failure rates of actions or activities when statistically significant data is absent.

Results of the parent-rated Strengths and Difficulties Questionnaire in 22,108 primary school students from 8 provinces of China  

PubMed Central

Background A valid screening tool for behavioral and emotional problems in children and adolescents is needed to promote psychological wellbeing and to prevent mental disorders in China's children. Aim Assess the use of the Chinese version of the internationally recognized Strengths and Difficulties Questionnaire (SDQ) – which assesses emotional symptoms, conduct problems, hyperactivity/inattention, peer relationship problems and prosocial behaviors – in a large sample of urban and rural children from different parts of China. Methods The Chinese version of the parent-reported SDQ was administered to legal guardians (primarily parents) of a stratified random sample of 22,108 primary school children 5 to 13 years of age from eight provinces in China. The association between SDQ scores and socio-demographic characteristics was assessed and the percentile cutoff scores for ‘abnormal’, ‘borderline’ and ‘normal’ results in China were compared with those for Japan and the United Kingdom. Results The internal consistency of the 4 of the 5 SDQ subscales were satisfactory but that for the ‘peer relationships problems’ subscale was quite poor (alpha=0.22). Guardians reported that boys were more likely than girls to have hyperactivity/inattention problems and that girls were more likely than boys to have problems with emotional symptoms. For both boys and girls hyperactivity/inattention problems decreased with age while peer relationship problems increased with age. Emotional symptoms, conduct problems and peer relationship problems were more common in children from rural areas and in children whose identified guardian was not a parent (i.e., a grandparent or other relative). The 90th percentile cutoff score for abnormal results was higher in Chinese children than the cutoff scores reported for children in Japan and the United Kingdom. Conclusions This study suggests that prevention programs for hyperactivity/inattention problems in boys need to start before the age of 10 and that training in methods of reducing the stress associated with peer relationships should start in early adolescence. Further work is needed to improve the cultural validity of the SDQ in China and to determine its sensitivity and specificity for identifying children who are in need of mental health services.

A new self-report quality of life questionnaire for children with neuromuscular disorders: presentation of the instrument, rationale for its development, and some preliminary results.  

PubMed

Improvement of quality of life in neuromuscular disorders is a primary objective, both in management of affected children and in the context of therapeutic trials. Quality of life is a subjective concept and it is crucial to gather information directly from patients. We created the SOLE Questionnaire for NMDs, a new instrument designed to investigate quality of life in children with neuromuscular disorders, and tested it in a study population of 78 patients and in 81 healthy children aged 5 to 13 years. The SOLE Questionnaire, characterized by a visual and neutral approach, was well received, practical, rapid to administer, and able to discriminate between patients and controls. We also confirmed the presence of disagreement about children's quality of life between children and their parents. We suggest that our new approach could help to improve understanding of quality of life in children with neuromuscular disorders. PMID:24352162

Somatic perception, cultural differences and immigration: results from administration of the Modified Somatic Perception Questionnaire (MSPQ) to a sample of immigrants  

PubMed Central

The number of immigrants in Italy has doubled every 10 years from 1972 and Genoa hosts two large communities of immigrants from South America and Africa. We investigated differences in the somatic perception between immigrants and Italians and between South Americans and Africans living in the city of Genoa. During a 7 month period, an anonymous questionnaire asking for sociodemographic information and the Modified Somatic Perception Questionnaire (MSPQ) were administered to all immigrants accessing an outpatient clinic or the general practitioners offices. MSPQ mean scores were significantly higher in immigrant patients than in Italian patients, after adjusting for sex and age differences. We found no differences between South Americans and Africans in MSPQ score. The tendency to express discomfort through physical symptoms appears to be related to being a foreigner who arrived in Italy through a migratory trip and also to being a person who comes from a cultural context that is very different from the one of developed countries.

A population based survey in Ethiopia using questionnaire as proxy to estimate obstetric fistula prevalence: results from demographic and health survey  

PubMed Central

Background Obstetric Fistula (OF) remains a major public health problem in areas where unattended obstructed labor is common and maternal mortality is high. Obstetric Fistula was able to be prevented, treated and eradicated in high-income countries; however, it still affects many women in low-income countries. To our knowledge, only few studies have described the prevalence and factors associated with Obstetric Fistula in Ethiopia in population-based surveys. Objective The aim of this study is to describe the prevalence and factors associated with Obstetric Fistula in Ethiopia. Methods The study used women’s dataset from the 2005 Ethiopian Demographic and Health Survey. The survey sample was designed to provide national, urban/rural, and regional representative estimates of key health and demographic indicators. The sample was selected using a two-stage stratified sampling process. OF was measured using questionnaire. The data is analyzed using descriptive and multivariate statistical methods to determine factors associated with Obstetric Fistula. Results A total of 14,070 women of reproductive age group were included in the survey. Of which 23.2% ever heard of obstetric fistula. Among women who ever given birth (9,713), some 103 (1.06%, 95% CI; 0.89%-1.31%) experienced obstetric fistula in their lifetime, which means 10.6 per 1000 women who ever gave birth. It is estimated that in Ethiopia nearly 142,387 (95% CI: 115,080-169,694) of obstetric fistula patients exist. Those women who are circumcised had higher odds of reporting the condition (Chi square = 4.41, p-value = 0.036). In the logistic regression model women from rural areas were less likely to report obstetric fistula than their urban counterparts (OR = 0.21, 95% CI: 0.06-0.69). Women who gave birth 10 or more had higher odds of developing obstetric fistula than women with 1-4 child (OR = 4.34; 95% CI; 1.29-14.55). Conclusions Obstetric fistula is a major public and reproductive health concern in Ethiopia. This calls for increased access to emergency obstetric care, expansion of fistula repair service and active finding of women with OF with campaigns of ending fistula is recommended.

Review of bubble detector response characteristics and results from space.  

PubMed

A passive neutron-bubble dosemeter (BD), developed by Bubble Technology Industries, has been used for space applications. Both the bubble detector-personal neutron dosemeter and bubble detector spectrometer have been studied at ground-based facilities in order to characterise their response due to neutrons, heavy ion particles and protons. This technology was first used during the Canadian-Russian collaboration aboard the Russian satellite BION-9, and subsequently on other space missions, including later BION satellites, the space transportation system, Russian MIR space station and International Space Station. This paper provides an overview of the experiments that have been performed for both ground-based and space studies in an effort to characterise the response of these detectors to various particle types in low earth orbit and presents results from the various space investigations.

Determinants of patient satisfaction in oncology settings from European and Asian countries: preliminary results based on the EORTC IN-PATSAT32 questionnaire.  

PubMed

The aim of this study was to identify factors associated significantly with hospitalised cancer patients' satisfaction with care. Patients were recruited from four geographical/cultural groups, including five European countries and Taiwan. They rated their level of satisfaction by completing the EORTC IN-PATSAT32 questionnaire at home. Additionally, data were collected on the sociodemographic and clinical characteristics and the quality of life of the patients, as well as on institutional characteristics. Of 762 patients recruited, 647 (85%) returned a completed questionnaire. The number of nurses and doctors per bed, institution size, geo-cultural origin, ward setting, teaching/non-teaching setting, treatment toxicity, global health status, participation in clinical trials and education level were all associated significantly at the multivariate level with satisfaction with doctor and nurse interpersonal skills, information provision, availability, and/or overall satisfaction. A number of patient-, institutional- and culture-related factors are associated with the perceived quality of cancer care. Future studies, with appropriate sampling frames and stratification procedures, are needed to better understand cross-national and cross-cultural differences in cancer patient satisfaction.

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.

Improving Response to Critical Laboratory Results with Automation  

PubMed Central

Objective: To evaluate the effect of an automatic alerting system on the time until treatment is ordered for patients with critical laboratory results. Design: Prospective randomized controlled trial. Intervention: A computer system to detect critical conditions and automatically notify the responsible physician via the hospital's paging system. Patients: Medical and surgical inpatients at a large academic medical center. One two-month study period for each service. Main outcomes: Interval from when a critical result was available for review until an appropriate treatment was ordered. Secondary outcomes were the time until the critical condition resolved and the frequency of adverse events. Methods: The alerting system looked for 12 conditions involving laboratory results and medications. For intervention patients, the covering physician was automatically notified about the presence of the results. For control patients, no automatic notification was made. Chart review was performed to determine the outcomes. Results: After exclusions, 192 alerting situations (94 interventions, 98 controls) were analyzed. The intervention group had a 38 percent shorter median time interval (1.0 hours vs. 1.6 hours, P = 0.003; mean, 4.1 vs. 4.6 hours, P = 0.003) until an appropriate treatment was ordered. The time until the alerting condition resolved was less in the intervention group (median, 8.4 hours vs. 8.9 hours, P = 0.11; mean, 14.4 hours vs. 20.2 hours, P = 0.11), although these results did not achieve statistical significance. The impact of the intervention was more pronounced for alerts that did not meet the laboratory's critical reporting criteria. There was no significant difference between the two groups in the number of adverse events. Conclusion: An automatic alerting system reduced the time until an appropriate treatment was ordered for patients who had critical laboratory results. Information technologies that facilitate the transmission of important patient data can potentially improve the quality of care.

End-of-life care and achieving preferences for place of death in England: Results of a population-based survey using the VOICES-SF questionnaire.  

PubMed

Background/aim: Health policy places emphasis on enabling patients to die in their place of choice, and increasing the proportion of home deaths. In this article, we seek to explore reported preferences for place of death and experiences of care in a population-based sample of deaths from all causes. Design: Self-completion post-bereavement survey. Setting/Participants: Census of deaths registered in two health districts between October 2009 and April 2010. Views of Informal Carers - Evaluation of Services Short Form was sent to each informant (n = 1422; usually bereaved relative) 6-12 months post-bereavement. Results: Response was 33%. In all, 35.7% of respondents reported that the deceased said where they wanted to die, and 49.3% of these were reported to achieve this. Whilist 73.9% of those who were reported to have a preference cited home as the preferred place, only 13.3% of the sample died at home. Cancer patients were more likely to be reported to achieve preferences than patients with other conditions (p < .01). Being reported to have a record of preferences for place of death increased the likelihood of dying at home (odds ratio = 22.10). When rating care in the last 2 days, respondents were more likely to rate 'excellent' or 'good' for nursing care (p < .01), relief of pain (p < .01) and other symptoms (p < .01), emotional support (p < .01) and privacy of patient's environment (p < .01) if their relative died in their preferred place. Conclusions: More work is needed to encourage people to talk about their preferences at the end of life: this should not be restricted to those known to be dying. Increasing knowledge and achievement of preferences for place of death may also improve end-of-life care. PMID:24292157

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.

The Norbeck Social Support Questionnaire.  

PubMed

The purpose of this paper is to summarize the development and testing of the Norbeck Social Support Questionnaire (NSSQ) and to discuss several issues that have arisen in recent use of the instrument. The NSSQ is a self-administered questionnaire that measures multiple dimensions of social support. Three functional properties--affect, affirmation, and aid--from Kahn's (1979) definition of social support are measured. The network properties of size, stability (duration of relationships), and accessibility (frequency of contact) are also measured, as well as changes in the convoy or support system due to losses of relationships. Nine categories are used to determine sources of support. Graduate students of nursing (N = 130) were used as subjects for several studies to test reliability and validity, and employed adults (N = 136) were used for additional validity testing and to provide normative data. Reliability was established through analysis of internal consistency and test-retest measures taken a week apart. Very high levels of internal consistency and test-retest reliability were found for the functional and network properties, and medium levels for the loss items. At a 7-month retesting, medium levels of stability were found, and the instrument was sensitive to changes in the network composition over time. Although the network composition changed, the overall level of functional support remained stable. Validity of the NSSQ was tested in relation to response bias and concurrent, construct, and predictive validity. The results indicated that the instrument is free from the response bias of social desirability. Medium levels of concurrent validity were shown with two other social support instruments. Construct validity was demonstrated by significant associations between NSSQ measures and two interpersonal constructs expected to be related to social support, while no significant relationships were found between the NSSQ measures and an unrelated interpersonal construct. Predictive validity was tested by examining the hypothesis that social support serves as a buffer for life stress. Among the functional properties, the interaction of aid and life stress accounted for 13.2% of the variance in negative mood. Of the network properties, duration of relationships had significant main and interaction effects, accounting together for 19.3% of the variance in negative mood. Normative data from a sample of employed adults provide means and standard deviations for each subscale and variable of the NSSQ, as well as descriptive data about sources of support.(ABSTRACT TRUNCATED AT 400 WORDS) PMID:6536338

European reference values for the quality of life questionnaire EORTC QLQ-C30: Results of a German investigation and a summarizing analysis of six European general population normative studies.  

PubMed

Abstract Background. The aims of this study are to present the results of a new general population normative study of the quality of life questionnaire EORTC QLQ-C30 and to give European reference values averaged across six studies. Methods. The empirical study was based on a representative sample of the German adult population (N = 2448). The subjects were asked to fill in several questionnaires, one of them being the EORTC QLQ-C30. Results. EORTC QLQ-C30 mean scores of this sample indicated slightly better quality of life (QoL) than in previous European studies. QoL decreased with age, but there were only small gender differences. The mean scores were compared with the age and gender adjusted scores of five other European normative studies from Sweden, the Netherlands, Norway, and Germany (N between 1731 and 4910). Finally, the data of these five studies and the new study were combined to arrive at averaged European normative values for the scales and the symptom items of the questionnaire. Conclusion. The reference values of the scales pooled across six European studies (N = 16 151) can be used as general population references for QoL scores of cancer patients. PMID:24456505

The Validation of the Spatial Hearing Questionnaire  

PubMed Central

Objectives Subjective questionnaires are informative in understanding the difficulties faced by patients with hearing loss. Our intent was to establish and validate a new questionnaire that encompasses situations emphasizing binaural hearing. The Spatial Hearing Questionnaire is a self-report assessment tool utilizing eight subscales representing questions pertaining to the perception of male, female, and children’s voices, music in quiet, source localization, understanding speech in quiet, and understanding speech in noise. Design The Spatial Hearing Questionnaire, composed of 24 items, is scored from 0–100. It was administered to 142 subjects using one or two cochlear implants. Speech perception and localization abilities were measured, and the Speech, Spatial and Other Qualities (SSQ) questionnaire was completed to evaluate validity of the questionnaire. Psychometric tests were done to test the reliability and factor structure of the Spatial Hearing Questionnaire. Results Results showed high internal consistency reliability (Cronbach’s ? = 0.98) and good construct validity (correlations between the Spatial Hearing Questionnaire and other test measures, including the SSQ, were significant). A preliminary factor analysis revealed scores loaded on three factors, representing the following conditions: localization, speech in noise and music in quiet, and speech in quiet, explaining 64.9, 13.0, and 5.3% of the variance, respectively. Most of the questionnaire items (12/24) loaded onto the first factor which represents the subscale related to source localization. Mean scores on the Spatial Hearing Questionnaire were higher for subjects with bilateral cochlear implants over subjects with a unilateral cochlear implant, consistent with other research and supporting construct validity. Conclusions The Spatial Hearing Questionnaire is a reliable and valid questionnaire which can be completed independently by most patients in about 10 minutes. It is likely to be a valuable tool for clinicians and researchers to measure spatial hearing abilities.

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.

American society of nephrology quiz and questionnaire 2013: transplantation.  

PubMed

The nephrology quiz and questionnaire remains an extremely popular session for attendees of the Annual Meeting of the American Society of Nephrology. As in past years, the conference hall was overflowing with interested audience members. Topics covered by expert discussants included electrolyte and acid-base disorders, glomerular disease, ESRD/dialysis, and transplantation. Complex cases representing each of these categories along with single best answer questions were prepared by a panel of experts. Before the meeting, program directors of United States nephrology training programs answered questions through an Internet-based questionnaire. A new addition to the nephrology quiz and questionnaire was participation in the questionnaire by nephrology fellows. To review the process, members of the audience test their knowledge and judgment on a series of case-oriented questions prepared and discussed by experts. Their answers are compared in real time using audience response devices with the answers of nephrology fellows and training program directors. The correct and incorrect answers are then briefly discussed after the audience responds, and the results of the questionnaire are displayed. This article recapitulates the session and reproduces its educational value for the readers of CJASN. Enjoy the clinical cases and expert discussions. PMID:24742474

COMPARISON OF RESPONSE OF 9977 TEST PACKAGES TO ANALYTICAL RESULTS  

SciTech Connect

Each of the hypothetical accident test cases for the 9977 prototypes was included in the battery of finite element structural analyses performed for the package. Comparison of the experimental and analytical results provides a means of confirming that the analytical model correctly represents the physical behavior of the package. The ability of the analytical model to correctly predict the performance of the foam overpack material for the crush test is of particular interest. The dissipation of energy in the crushing process determines the deceleration of the package upon impact and the duration of the impact. In addition, if the analytical model correctly models the foam behavior, the predicted deformation of the package will match that measured on the test articles. This study compares the deformations of the test packages with the analytical predictions. In addition, the impact acceleration and impact duration for the test articles are compared with those predicted by the analyses.

Defects in regulation of local immune responses resulting in atherosclerosis.  

PubMed

Atherosclerosis is nowadays generally accepted as an inflammatory disease but the mechanism of its origin and development have not yet been fully clarified. The present review focuses on the role of the local immune system as one of the key players in the pathogenesis of the complex process. Its part represented by vascular-associated lymphoid tissue (VALT) within the arterial wall participates directly in the vascular wall's homeostatis. Its inordinate activation during ontogenic development of an individual, this formerly defensive and physiologic mechanism transform into a pathological process resulting in an impairing inflammation. Hsp60, CRP and oxidized or otherwise modified LDL are serious candidates for triggering these pathological changes. The principal role is played by anti-Hsp60 antibodies and by shear stress originating on the surface of endothelium due to blood flow. The experimental and clinical data supporting this immunological hypothesis of atherosclerosis are discussed. PMID:16295529

Telephone interviews and online questionnaires can be used to improve neurodevelopmental follow-up rates  

PubMed Central

Background Maximising response rates to neurodevelopmental follow-up is a key challenge for paediatric researchers. We have investigated the use of telephone interviews and online questionnaires to improve response rates, reduce non-response bias, maintain data completeness and produce unbiased outcomes compared with postal questionnaires when assessing neurodevelopmental outcomes at 2 years. Methods A prospective cohort study of babies born ?32 weeks gestation. Neurodevelopmental outcomes were assessed at 2 years of age using a parent questionnaire completed via post, telephone or online. Relative Risks with 95% confidence intervals (RR; 95% CI) were calculated to identify participant characteristics associated with non-response and questionnaire response mode (postal vs. telephone/online). The proportion of missing data and prevalence of adverse outcomes was compared between response modes using generalized linear models. Results Offering telephone/online questionnaires increased the study response rate from 55% to 60%. Telephone/online responders were more likely to be non-white (RR 1.6; [95% CI 1.1, 2.4]), non-English speaking (1.6; [1.0, 2.6]) or have a multiple birth (1.6; [1.1, 2.3]) than postal responders. There were no significant differences in the prevalence of adverse neurodevelopmental outcomes between those who responded via post vs. telephone/online (1.1; [0.9, 1.4]). Where parents attempted all questionnaire sections, there were no significant differences in the proportion of missing data between response modes. Conclusions Where there is sufficient technology and resources, offering telephone interviews and online questionnaires can enhance response rates and improve sample representation to neurodevelopmental follow-up, whilst maintaining data completeness and unbiased outcomes.

Interaction between gas cooking and GSTM1 null genotype in bronchial responsiveness: results from the European Community Respiratory Health Survey  

PubMed Central

Background Increased bronchial responsiveness is characteristic of asthma. Gas cooking, which is a major indoor source of the highly oxidant nitrogen dioxide, has been associated with respiratory symptoms and reduced lung function. However, little is known about the effect of gas cooking on bronchial responsiveness and on how this relationship may be modified by variants in the genes GSTM1, GSTT1 and GSTP1, which influence antioxidant defences. Methods The study was performed in subjects with forced expiratory volume in one second at least 70% of predicted who took part in the multicentre European Community Respiratory Health Survey, had bronchial responsiveness assessed by methacholine challenge and had been genotyped for GSTM1, GSTT1 and GSTP1-rs1695. Information on the use of gas for cooking was obtained from interviewer-led questionnaires. Effect modification by genotype on the association between the use of gas for cooking and bronchial responsiveness was assessed within each participating country, and estimates combined using meta-analysis. Results Overall, gas cooking, as compared with cooking with electricity, was not associated with bronchial responsiveness (?=?0.08, 95% CI ?0.40 to 0.25, p=0.648). However, GSTM1 significantly modified this effect (? for interaction=?0.75, 95% CI ?1.16 to ?0.33, p=4×10?4), with GSTM1 null subjects showing more responsiveness if they cooked with gas. No effect modification by GSTT1 or GSTP1-rs1695 genotypes was observed. Conclusions Increased bronchial responsiveness was associated with gas cooking among subjects with the GSTM1 null genotype. This may reflect the oxidant effects on the bronchi of exposure to nitrogen dioxide.

American society of nephrology quiz and questionnaire 2013: glomerulonephritis.  

PubMed

The Nephrology Quiz and Questionnaire (NQ&Q) remains an extremely popular session for attendees of the Annual Meeting of the American Society of Nephrology. As in past years, the conference hall of the 2013 meeting was overflowing with interested audience members. Topics covered by expert discussants included electrolyte and acid-base disorders, glomerular disease, ESRD/dialysis, and transplantation. Complex cases representing each of these categories, along with single best answer questions, were prepared by a panel of experts. Before the meeting, program directors of United States nephrology training programs answered questions through an Internet-based questionnaire. A new addition to the NQ&Q was participation in the questionnaire by nephrology fellows. To review the process, members of the audience test their knowledge and judgment on a series of case-oriented questions prepared and discussed by experts. Their answers are compared in real time using audience response devices with the answers of nephrology fellows and training program directors. The correct and incorrect answers are then briefly discussed after the audience responses and the results of the questionnaire are displayed. This article recapitulates the session and reproduces its educational value for CJASN readers. Enjoy the clinical cases and expert discussions. PMID:24578330

Clinical trial participants' experiences of completing questionnaires: a qualitative study  

PubMed Central

Objectives To improve clinical study developments for elderly populations, we aim to understand how they transfer their experiences into validated, standardised self-completed study measurement instruments. We analysed how women (mean 78±8?years of age) participating in a randomised controlled trial (RCT) cognised study instruments used to evaluate outcomes of the intervention. Setting The interview study was nested in an RCT on chronic neck pain using common measurement instruments situated in an elderly community in Berlin, Germany, which comprised of units for independent and assisted-living options. Participants The sample (n=20 women) was selected from the RCT sample (n=117, 95% women, mean age 76 (SD±8)?years). Interview participants were selected using a purposive sampling list based on the RCT outcomes. Outcomes We asked participants about their experiences completing the RCT questionnaires. Interviews were analysed thematically, then compared with the questionnaires. Results Interviewees had difficulties in translating complex experiences into a single value on a scale and understanding the relationship of the questionnaires to study aims. Interviewees considered important for the trial that their actual experiences were understood by trial organisers. This information was not transferrable by means of the questionnaires. To rectify these difficulties, interviewees used strategies such as adding notes, adding response categories or skipping an item. Conclusions Elderly interview participants understood the importance of completing questionnaires for trial success. This led to strategies of completing the questionnaires that resulted in ‘missing’ or ambiguous data. To improve data collection in elderly populations, educational materials addressing the differential logics should be developed and tested. Pilot testing validated instruments using cognitive interviews may be particularly important in such populations. Finally, when the target of an intervention is a subjective experience, it seems important to create a method by which participants can convey their personal experiences. These could be nested qualitative studies. Trial registration number ISRCTN77108101807.

Performance of commonly used respiratory questionnaire items in a cohort of infants born preterm  

PubMed Central

Background Items from respiratory questionnaires validated in older children are often used in research studies of preterm infants, although they have not been validated in this population. We aimed to assess both test-retest reliability and convergent validity of a group of commonly used respiratory questionnaire items in a cohort of preterm infants. Methods The health status of 300 preterm infants was assessed by telephone questionnaire as part of a prospective cohort study. The questionnaire items analyzed in this study included six commonly used respiratory questions. The questionnaire responses used in this analysis were from the telephone follow-up in this cohort at six months of age adjusted for prematurity. A repeat interview one to two weeks after this interview was performed in a subset of subjects to assess test-retest reliability. The convergent validity of the respiratory items was also assessed by calculating the associations among the responses to the respiratory questions. Results A total of 43 infants were singletons that met the criteria for test-retest reliability analysis. All of the respiratory questions demonstrated fair to strong test-retest reliability. Among 206 respondents, respiratory questionnaire items also demonstrated strong convergent validity, in that caretakers reporting wheezing or whistling in the chest were significantly more likely to also report other respiratory events. Conclusions This selection of standard respiratory questionnaire items performed well for research purposes in this population.

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.

Use of a safety climate questionnaire in UK health care: factor structure, reliability and usability  

PubMed Central

Aim To explore the factor structure, reliability, and potential usefulness of a patient safety climate questionnaire in UK health care. Setting Four acute hospital trusts and nine primary care trusts in England. Methods The questionnaire used was the 27 item Teamwork and Safety Climate Survey. Thirty three healthcare staff commented on the wording and relevance. The questionnaire was then sent to 3650 staff within the 13 NHS trusts, seeking to achieve at least 600 responses as the basis for the factor analysis. 1307 questionnaires were returned (36% response). Factor analyses and reliability analyses were carried out on 897 responses from staff involved in direct patient care, to explore how consistently the questions measured the underlying constructs of safety climate and teamwork. Results Some questionnaire items related to multiple factors or did not relate strongly to any factor. Five items were discarded. Two teamwork factors were derived from the remaining 11 teamwork items and three safety climate factors were derived from the remaining 11 safety items. Internal consistency reliabilities were satisfactory to good (Cronbach's alpha ?0.69 for all five factors). Conclusions This is one of the few studies to undertake a detailed evaluation of a patient safety climate questionnaire in UK health care and possibly the first to do so in primary as well as secondary care. The results indicate that a 22 item version of this safety climate questionnaire is useable as a research instrument in both settings, but also demonstrates a more general need for thorough validation of safety climate questionnaires before widespread usage.

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.

Objective The aim of this study was to cross-culturally adapt the Armando Patient Satisfaction Questionnaire into Arabic and validate its use in the general population. Methods The translation was conducted based on the principles of the most widely used model in questionnaire translation, namely Brisling’s back-translation model. A written authorization allowing translation into Arabic was obtained from the original author. The Arabic version of the questionnaire was distributed to 480 participants to evaluate construct validity. Statistical Package for Social Sciences version 17.0 for Windows was used for the statistical analysis. Results The response rate of this study was 96%; most of the respondents (52.5%) were female. Internal consistency was assessed using Cronbach’s ?, which showed that this questionnaire provides a high reliability coefficient (reaching 0.9299) and a high degree of consistency and thus can be relied upon in future patient satisfaction research.

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.

How to use Outcome Questionnaires: Pearls and Pitfalls  

PubMed Central

Outcome questionnaires are increasingly used in the current medical practice. Patient reported outcomes serve as an essential and perhaps more relevant means for assessing patients’ response to treatment than clinical measures alone. Many of the procedures performed in plastic surgery are associated with aesthetic outcomes, therefore it is pertinent to thoroughly understand the patient’s perspective of achieved results. Surgeons need to possess the knowledge and skills about outcomes assessments and understand how to apply them to improve quality of care delivered based on evidence. This paper discusses the appropriate use of outcome questionnaires to rigorously evaluate treatment methods based on patient satisfaction and the outcome measurement instruments frequently used in plastic surgery.

Validation of a care and comfort hypertonicity questionnaire.  

PubMed

The lack of evidence regarding functional and quality of life benefits resulting from tone reduction with intrathecal baclofen (ITB) infusion treatment relates to the lack of validated and responsive measures. We integrated our scale/questionnaire, developed from chart review, with the non-validated Caregiver Questionnaire (CQ) to yield a final document, the Care and Comfort Hypertonicity Questionnaire (CCHQ). Convergent validity was achieved by administering the CCHQ to 47 patients with spastic/dystonic cerebral palsy (CP) who were being evaluated for tone management. The population studied included 18 females and 29 males (mean age 10y [SD 4y 10mo]; range 3y 1mo-21y 1mo). Twenty-five patients were subsequently referred for botulinum toxin (BTX-A) injections (mean Gross Motor Function Classification System [GMFCS] 3.2); 11 patients were referred for ITB (mean GMFCS 4.4); four were referred for orthopedic surgery (mean GMFCS 3.3); 3 were referred for selective dorsal rhizotomy (mean GMFCS 2.7); one was recommended for oral baclofen (GMFCS 5); and three were recommended for no treatment (mean GMFCS 3.7). Blinded to the score, those with the highest scores (severe hypertonicity) were recommended for ITB; those with the lowest scores were recommended for BTX-A injections. Responsiveness of the CCHQ was established by administering the questionnaire to patients who already had an implanted ITB pump. The children with the largest dose increase demonstrated a statistically significant improvement in the CCHQ score. This scale can be used to document the efficacy of treating severe hypertonicity both in clinical and research protocols. PMID:16483393

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.

Validation in London of a physical activity questionnaire for use in a study of postmenopausal osteopaenia.  

PubMed Central

STUDY OBJECTIVE: To determine the validity of a self administered physical activity questionnaire to be used as part of a screening device for postmenopausal osteopaenia (with additional questions on medical history and calcium intake). DESIGN: A questionnaire was posted to 86 perimenopausal women to enquire about weekly hours spent in non-sedentary activity at work, in the household, and during leisure hours. Subjects who returned the questionnaire were visited at home and asked to complete a four day activity diary and subsequently to undertake a submaximal estimate of VO2 MAX, carried out using a treadmill ergometer. They were interviewed to clarify questionnaire and diary entries. Questionnaire validity was assessed in comparison with the diary estimates of hours of activity and with VO2 MAX. PARTICIPANTS: A total of 86 perimenopausal women aged 43-54 years were randomly selected from a GP list in Hammersmith, London. Thirty five women (41%) returned the questionnaire. They were visited at home, given the diary to complete, and invited to attend the physiology laboratory for VO2 MAX measurements. Twenty six of the 35 (74%) completed the study and were included in the final analysis. MAIN RESULTS: Women spent an average of 51 hours per week in non-sedentary activities. Questionnaire and diary yielded similar results (51.05 versus 51.30 h/wk), and there was a good correlation between diary and questionnaire estimates of total weekly hours of non-sedentary activity (r = 0.45, p < 0.05). Other significant correlations were for standing (r = 0.69, p < 0.01), leisure activities (r = 0.66, p < 0.01), and for light household activities (r = 0.42, p < 0.05). Correlations were better for employed than non-employed subjects. In relation to the diary, the questionnaire correctly classified 60% into the top or bottom half of the distribution activity. Sensitivity and specificity of the questionnaire were both equal to 61.5%. CONCLUSIONS: The questionnaire is useful for classifying subjects according to their level of activity, especially when administered in conjunction with an interview. The four day diary provided a useful reference measure and a focus for discussing activity patterns during an interview related to the questionnaire responses.

Smallpox Still Haunts Scientists: Results of a Questionnaire-Based Inquiry on the Views of Health Care and Life Science Experts and Students on Preserving the Remaining Variola Virus Stocks  

PubMed Central

The World Health Organization (WHO) declared eradication of the dreadful disease “smallpox” in 1980. Though the disease has died down, the causative virus “variola” has not, as it has been well preserved in two high security laboratories—one in USA and another in Russia. The debate on whether the remaining stocks of the smallpox virus should be destroyed or not is ongoing, and the World Health Assembly (WHA) in 2011 has decided to postpone the review on this debate to the 67th WHA in 2014. A short questionnaire-based inquiry was organized during a one-day stem cell meeting to explore the views of various health care and life science specialists especially students on this aspect. Among the 200 participants of the meeting, only 66 had answered the questionnaire. 60.6% of participants who responded to the questionnaire were for preserving the virus for future reference, while 36.4% of the participants were for destroying the virus considering the magnitude with which it killed millions. However, 3% of the respondents were not able to decide on any verdict. Therefore, this inquiry expresses the view that “what we cannot create, we do not have the right to destroy.”

Development of the young spine questionnaire  

PubMed Central

Background Back pain in children is common and early onset of back pain has been shown to increase the risk of back pain significantly in adulthood. Consequently, preventive efforts must be targeted the young population but research relating to spinal problems in this age group is scarce. Focus has primarily been on the working age population, and therefore specific questionnaires to measure spinal pain and its consequences, specifically aimed at children and adolescents are absent. The purpose of this study was to develop a questionnaire for schoolchildren filling this gap. Methods The Young Spine Questionnaire (YSQ) was developed in three phases – a conceptualisation, development and testing phase. The conceptualisation phase followed the Wilson and Cleary model and included questions regarding spinal prevalence estimates, pain frequency and intensity, activity restrictions, care seeking behaviour and influence of parental back trouble. Items from existing questionnaires and the “Revised Faces Pain Scale” (rFPS) were included during the development phase. The testing phase consisted of a mixed quantitative and qualitative iterative method carried out in two pilot tests using 4th grade children and focusing on assessment of spinal area location and item validity. Results The testing phase resulted in omission of the pain drawings and the questions and answer categories were simplified in several questions. Agreement between the questionnaire prevalence estimates and the interviews ranged between 83.7% (cervical pain today) and 97.9% (thoracic pain today). To improve the understanding of the spinal boundaries we added bony landmarks to the spinal drawings after pilot test I. This resulted in an improved sense of spinal boundary location in pilot test II. Correlations between the rFPS and the interview pain score ranged between 0.67 (cervical spine) and 0.79 (lumbar spine). Conclusions The Young Spine Questionnaire contains questions that assess spinal pain and its consequences. The items have been tested for content understanding and agreement between questionnaire scores and interview findings among target respondents. These preliminary results suggest that the YSQ is feasible, has content validity and is a well understood questionnaire to be used in studies of children aged 9 to 11 years.

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.

Development of a Web-based questionnaire to collect exposure and symptom data in children and adolescents with asthma  

PubMed Central

Background Questionnaires are an important component of epidemiologic studies. Maintaining compliance in longitudinal studies is a challenge, particularly from children and adolescents. Objective To implement a Web-based questionnaire for children and adolescents with asthma for daily self-completion, minimizing recall bias and maximizing compliance. Methods We determined symptoms, exposure to asthma triggers, peak expiratory flow rate, and medications taken, including dose and dose time. The Web-based system can be less time-consuming and a source of fewer errors than paper questionnaires and permits review of the data and compliance during the study. The Web programming of the questionnaire included branching, so that questions deemed irrelevant based on a previous response were not presented to participants, minimizing the completion time. Results Sixty-four students with asthma participated nearly daily for between 2 and 4 months. Financial incentives for the participants were calculated in real time based on completion rates. Monitoring of the subject’s completion included an extensive administrative hierarchical alert system, enabling the staff to target individuals who fell behind in entries and needed the most encouragement. Conclusions Similar compliance and completion rates were obtained using the Web-based questionnaire as reported for smaller paper questionnaires by parents of children. The Web-based system provides a mechanism to obtain daily responses directly from an age group not often accessible by traditional questionnaire approaches.

Quasi-Linear Cochlear Responses to Noise Can Result from Instantaneous Nonlinearities  

NASA Astrophysics Data System (ADS)

Responses to acoustic stimuli in the cochlea are known to be nonlinear. Many existing models of cochlear mechanics were built upon three basic assumptions: traveling-wave amplification is provided by active mechanisms in the outer hair cells (OHCs). Second, as the stimulus level increases, the gain decreases due to saturation nonlinearity in the OHCs. Finally, the saturation non-linearity is ``instantaneous'' its input-output relation does not possess memory. These assumptions were recently challenged by reports that basilar-membrane (BM) responses to noise can be predicted well by level-dependent Wiener filters and are thus quasi-linear. It was argued that the quasi-linear responses could not result from instantaneous nonlinearity. In this paper, we present a model of cochlear mechanics which has instantaneous OHC saturation nonlinearity but produces quasi-linear responses to noise. Correlation coefficients were consistently greater than 0.9 between simulated noise responses and the responses predicted by equivalent Wiener filters. Further, Gaussianity in the acoustic stimuli was preserved on the BM. We conclude that the results support the common understandings and assumptions of cochlear mechanics.

Improving access for patients - a practice manager questionnaire  

PubMed Central

Background The administrative and professional consequences of access targets for general practices, as detailed in the new GMS contract, are unknown. This study researched the effect of implementing the access targets of the new GP contract on general practice appointment systems, and practice manager satisfaction in a UK primary health care setting. Methods A four-part postal questionnaire was administered. The questionnaire was modified from previously validated questionnaires and the findings compared with data obtained from the Western Health and Social Services Board (WHSSB) in N Ireland. Practice managers from the 59 general practices in the WHSSB responded to the questionnaire. Results There was a 94.9% response rate. Practice managers were generally satisfied with the introduction of access targets for patients. Some 57.1% of responding practices, most in deprived areas (Odds ratio 3.13 -95% CI 1.01 – 9.80, p = 0.0256) had modified their appointment systems. Less booking flexibility was reported among group practices (p = 0.006), urban practices (p < 0.001) and those with above average patient list sizes (p < 0.001). Receptionists had not received training in patient appointment management in a quarter of practices. Practices with smaller list sizes were more likely than larger ones to utilise nurses in seeing extra patients (p = 0.007) or to undertake triage procedures (p = 0.062). Conclusion The findings demonstrated the ability of general practices within the WHSSB to adjust to a demanding component of the new GP contract. Issues relating to the flexibility of patient appointment booking systems, receptionists' training and the development of the primary care nursing role were highlighted by the study.

Translation into Portuguese of questionnaires to assess knee injuries  

PubMed Central

The aim of this systematic review was to review the quality of the translation and the measurement properties from questionnaires that assess injuries of the knee. We included questionnaires that were developed in foreign language and have been translated and validated into Portuguese. The databases used were CINAHL, SPORTDiscus, LILACS, PUBMED and SCIELO and the final search resulted in a total of 868 studies included, from which 16 were eligible. Most included questionnaires presented all steps expected in a translation process; however there were some deficiencies in measurement properties among the questionnaires. The VISA-P Brazil was the best questionnaire when analyzing translation process and measurement properties tested. It was the only questionnaire that tested all measurement properties investigated and presented adequate values for all of them. KOS-ADLS was the best questionnaire translated to Portuguese from Portugal. Among all, the VISA-P Brazil is the best questionnaire to be used with Brazilian Portuguese speakers when the condition is related to patellar tendinopathy and the LEFS is the best questionnaire for other general conditions of the knee. For Portuguese from Portugal, the best questionnaire is the KOS-ADLS, and like the LEFS it does not target any specific injury.

Usual Dietary Intakes: NHANES Food Frequency Questionnaire (FFQ)  

Cancer.gov

NCI developed a new instrument called the NHANES Food Frequency Questionnaire (formerly called Food Propensity Questionnaire) and supported its application in the National Health and Nutrition Examination Survey (NHANES). This instrument collects much of the same information as a food frequency questionnaire (FFQ), but without asking about portion size. The resulting data can be employed in the NCI usual dietary intakes model as covariates. By not asking about portion size, the NHANES FFQ requires less respondent burden than other FFQs.

A Symptom Survey and Quality of Life Questionnaire for Nasolacrimal Duct Obstruction in Children  

PubMed Central

Purpose To develop and validate a new parental questionnaire addressing symptoms and health related quality of life (HRQL) in congenital nasolacrimal duct obstruction (NLDO). Design Cross-sectional study. Participants Children aged 6 to <48 months with and without clinical signs of NLDO. Methods A new questionnaire was developed using semi-structured interviews with parents of children with NLDO and through discussions with expert clinicians. Questionnaires were completed by parents of children with NLDO and without NLDO. Cronbach’s alpha was calculated as a measure of internal-consistency reliability. Factor analysis was used to evaluate a priori subscales; symptoms and HRQL. Discriminant construct validity was assessed by comparing questionnaire scores between children with and without NLDO and between affected and unaffected eyes of children with unilateral NLDO. Instrument responsiveness was determined by comparing pre- and post-surgical intervention scores in a subset of NLDO subjects who underwent surgical treatment. Main outcome measure NLDO questionnaire score. Results 87 children were enrolled, 56 with NLDO and 31 without. All but two questions on the questionnaire showed a good distribution of responses, a high correlation with the rest of the questionnaire and excellent discrimination between patients with and without NLDO. Cronbach’s alpha values were good for the overall questionnaire (0.95), and for two predetermined subscales; symptoms (0.95) and HRQL (0.85). On a 0 to 4 scale, NLDO patients had worse scores compared to non-NLDO patients for both symptoms (mean difference = 2.1; 95% confidence interval (CI): 1.8 to 2.4) and HRQL (mean difference 1.2; 95% CI: 0.8 to 1.5) subscales. NLDO patients had worse scores pre-intervention compared to post-intervention for both the symptoms (mean difference = 2.2; 95% CI: 1.6 to 2.9) and HRQL (mean difference = 1.4; 95% CI: 0.8 to 2.1) subscales. Finally, NLDO patients had worse symptom scores for affected eyes compared to unaffected eyes (mean difference = 2.3; 95% CI: 1.9 to 2.6). Conclusions This novel NLDO questionnaire is useful in quantifying parental perception of symptoms and HRQL in childhood NLDO. The questionnaire may have a role in future clinical studies of NLDO

Patient understanding of and responses to multiplex genetic susceptibility test results  

PubMed Central

Purpose Examination of patients’ responses to direct-to-consumer genetic susceptibility tests is needed to inform clinical practice. This study examined patients’ recall and interpretation of, and responses to, genetic susceptibility test results provided directly by mail. Methods This observational study had 3 prospective assessments (before testing; 10 days after receiving results; 3 months later). Participants were 199 patients aged 25–40 who received free genetic susceptibility testing for 8 common health conditions. Results Over 80% correctly recalled their results for the 8 health conditions. Patients were unlikely to interpret genetic results as deterministic of health outcomes (mean=6.0, SD=0.8 on 1–7 scale, 1 indicating strongly deterministic). In multivariate analyses, patients with the least deterministic interpretations were White (p=.0098), more educated (p=.0093), and least confused by results (p=.001). Only 1% talked about their results with a provider. Conclusion Findings suggest that most patients will correctly recall their results and will not interpret genetics as the sole cause of diseases. The subset of those confused by results could benefit from consultation with a health care provider, which could emphasize that health habits currently are the best predictors of risk. Providers could leverage patients’ interest in genetic tests to encourage behavior changes to reduce disease risk.

The psychometric properties of the Child Feeding Questionnaire (CFQ) in Turkey.  

PubMed

The purpose of this study was to test the reliability and validity of the Child Feeding Questionnaire (CFQ) among Turkish parents. The questionnaire was administered to 490 participants. Construct validity was assessed by principal component factor analysis with varimax rotation and reliability was tested by Cronbach's alpha coefficient. For testing criterion-related validity, EAT-40 with DEBQ was also administered to 490 participants. Results showed the presence of seven major factors (perceived responsibility, perceived parent weight, perceived child weight, concern about child weight, pressure to eat, monitoring and restriction) with loadings similar to those of the original questionnaire. Seven subscales of the CFQ had higher internal consistency and test-retest reliability. This study clearly demonstrates the factorial validity and the reliability of a Turkish version of the CFQ.

A Parent-Mediated Intervention That Targets Responsive Parental Behaviors Increases Attachment Behaviors in Children with ASD: Results from a Randomized Clinical Trial.  

PubMed

The current study is a randomized clinical trial evaluating the efficacy of Focused Playtime Intervention (FPI) in a sample of 70 children with Autism Spectrum Disorder. This parent-mediated intervention has previously been shown to significantly increase responsive parental communication (Siller et al. in J Autism Dev Disord 43:540-555, 2013a). The current analyses focus on children's attachment related outcomes. Results revealed that children who were randomly assigned to FPI showed bigger increases in attachment-related behaviors, compared to children assigned to the control condition. Significant treatment effects of FPI were found for both an observational measure of attachment-related behaviors elicited during a brief separation-reunion episode and a questionnaire measure evaluating parental perceptions of child attachment. The theoretical and clinical implications of these findings are discussed. PMID:24488157

Analyzing the uncertainty of simulation results in accident reconstruction with Response Surface Methodology.  

PubMed

This paper is focused on the uncertainty of simulation results in accident reconstruction. The Upper and Lower Bound Method (ULM) and the Finite Difference Method (FDM), which can be easily applied in this field, are introduced firstly; the Response Surface Methodology (RSM) is then introduced into this field as an alternative methodology. In RSM, a sample set is firstly generated via uniform design; secondly, experiments are conducted according to the sample set with the help of simulation methods; thirdly, a response surface model is determined through regression analysis; finally, the uncertainty of simulation results can be analyzed using a combination of the response surface model and existing uncertainty analysis methods. It is later discussed in detail how to generate a sample set, how to calculate the range of simulation results and how to analyze the parameter sensitivity in RSM. Finally, the feasibility of RSM is validated by five cases. Moreover, the applicability of RSM, ULM and FDM in analyzing the uncertainty of simulation results is studied; the phenomena that ULM and FDM can hardly work while RSM can is found in the latter two cases. After an analysis of these five cases and the number of simulation runs required for each method, both advantages and disadvantages of these uncertainty analysis methods are indicated. PMID:21908115

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

NASA Astrophysics Data System (ADS)

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 over-estimate 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. Discussed here is 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 line voltage is then performed and surface plots of these peak voltages are presented.

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.

Sexual behavioral abstine HIV/AIDS questionnaire: Validation study of an Iranian questionnaire  

PubMed Central

Background: This study was designed to assess the validity and reliability of the designed sexual, behavioral abstinence, and avoidance of high-risk situation questionnaire (SBAHAQ), with an aim to construct an appropriate development tool in the Iranian population. Materials and Methods: A descriptive–analytic study was conducted among female undergraduate students of Tehran University, who were selected through cluster random sampling. After reviewing the questionnaires and investigating face and content validity, internal consistency of the questionnaire was assessed by Cronbach's alpha. Explanatory and confirmatory factor analysis was conducted using SPSS and AMOS 16 Software, respectively. Results: The sample consisted of 348 female university students with a mean age of 20.69 ± 1.63 years. The content validity ratio (CVR) coefficient was 0.85 and the reliability of each section of the questionnaire was as follows: Perceived benefit (PB; 0.87), behavioral intention (BI; 0.77), and self-efficacy (SE; 0.85) (Cronbach's alpha totally was 0.83). Explanatory factor analysis showed three factors, including SE, PB, and BI, with the total variance of 61% and Kaiser–Meyer–Olkin (KMO) index of 88%. These factors were also confirmed by confirmatory factor analysis [adjusted goodness of fitness index (AGFI) = 0.939, root mean square error of approximation (RMSEA) = 0.039]. Conclusion: This study showed the designed questionnaire provided adequate construct validity and reliability, and could be adequately used to measure sexual abstinence and avoidance of high-risk situations among female students.

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.

The agreement between workers and within workers in regard to occupational exposure to mercury in dental practice assessed from a questionnaire and an interview  

PubMed Central

Background The correct assessment and classification of exposure is essential in epidemiology. The validity of exposure data obtained by the use of questionnaires is, however, seldom evaluated. When conducting a study on the possible health effects from mercury exposure in dental practice, we compared answers on exposure from a job-specific questionnaire with answers to the same questions given at an interview 6 to 18 months later. Methods We examined the concordance between workers by comparing answers to the questionnaire given by persons working in the same clinics during the same time spans and the agreement within workers by comparing answers to the same questions from a questionnaire and from an interview. Other aims were to see if there was a difference in the answers to the questionnaire across job titles and to study the impact of missing information on the response rate in a detailed questionnaire. Results There was a marked difference between the pairs of employees working in the same clinic regarding the start and termination years for the different preparation methods, and this was partly independent of their occupation. Kappa values for using different preparation methods in the questionnaire and at the interview varied between 0.41(moderate) to 0.88(very good). Conclusions The results of this study indicate that a mailed questionnaire will cause misclassification of exposure. The observed occurrence of false positive exposure classifications from the questionnaire compared to the interview was higher than for false negative. This is important and may result in serious bias if the prevalence of exposure is low. Due to missing information, detailed questionnaires may also be inefficient if the goal is to construct exposure measures from combinations of several answers in the questionnaire.

COVD-QOL questionnaire: An adaptation for school vision screening using Rasch analysis  

PubMed Central

Purpose To adapt the College of Optometrist in Vision Development (COVD-QOL) questionnaire as a vision screening tool for primary school children. Methods An interview session was conducted with children, teachers or guardians regarding visual symptoms of 88 children (45 from special education classes and 43 from mainstream classes) in government primary schools. Data was assessed for response categories, fit items (infit/outfit: 0.6–1.4) and separation reliability (item/person: 0.80). The COVD-QOL questionnaire results were compared with vision assessment in identifying three categories of vision disorders: reduce visual acuity, accommodative response anomaly and convergence insufficiency. Analysis on the screening performance using the simplified version of the questionnaire was evaluated based on receiver-operating characteristic analysis for detection of any type of target conditions for both types of classes. Predictive validity analysis was used a Spearman rank correlation (>0.3). Results Two of the response categories were underutilized and therefore collapsed to the adjacent category and items were reduced to 14. Item separation reliability for the simplified version of the questionnaire was acceptable (0.86) but the person separation reliability was inadequate for special education classes (0.79) similar to mainstream classes (0.78). The discriminant cut-off score of 9 (mainstream classes) and 3 (special education classes) from the 14 items provided sensitivity and specificity of (65% and 54%) and (78% and 80%) with Spearman rank correlation of 0.16 and 0.40 respectively. Conclusion The simplified version of COVD-QOL questionnaire (14-items) performs adequately among children in special education classes suggesting its suitability as a vision screening tool.

The Generic Short Patient Experiences Questionnaire (GS-PEQ): identification of core items from a survey in Norway  

PubMed Central

Background Questionnaires are commonly used to collect patient, or user, experiences with health care encounters; however, their adaption to specific target groups limits comparison between groups. We present the construction of a generic questionnaire (maximum of ten questions) for user evaluation across a range of health care services. Methods Based on previous testing of six group-specific questionnaires, we first constructed a generic questionnaire with 23 items related to user experiences. All questions included a "not applicable" response option, as well as a follow-up question about the item's importance. Nine user groups from one health trust were surveyed. Seven groups received questionnaires by mail and two by personal distribution. Selection of core questions was based on three criteria: applicability (proportion "not applicable"), importance (mean scores on follow-up questions), and comprehensiveness (content coverage, maximum two items per dimension). Results 1324 questionnaires were returned providing subsample sizes ranging from 52 to 323. Ten questions were excluded because the proportion of "not applicable" responses exceeded 20% in at least one user group. The number of remaining items was reduced to ten by applying the two other criteria. The final short questionnaire included items on outcome (2), clinician services (2), user involvement (2), incorrect treatment (1), information (1), organisation (1), and accessibility (1). Conclusion The Generic Short Patient Experiences Questionnaire (GS-PEQ) is a short, generic set of questions on user experiences with specialist health care that covers important topics for a range of groups. It can be used alone or with other instruments in quality assessment or in research. The psychometric properties and the relevance of the GS-PEQ in other health care settings and countries need further evaluation.

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.

Behavioural, emotional, and cognitive responses in European disasters: results of survivor interviews.  

PubMed

In the European multi-centre study BeSeCu (Behaviour, Security, Culture), interviews were conducted in seven countries to explore survivors' emotional, behavioural, and cognitive responses during disasters. Interviews, either in groups or one-to-one, were convened according to type of event: collapse of a building; earthquake; fire; flood; and terror attack. The content analysis of interviews resulted in a theoretical framework, describing the course of the events, behavioural responses, and the emotional and cognitive processing of survivors. While the environmental cues and the ability to recognise what was happening varied in different disasters, survivors' responses tended to be more universal across events, and most often were adaptive and non-selfish. Several peri-traumatic factors related to current levels of post-traumatic stress were identified, while memory quantity did not differ as a function of event type or post-traumatic stress. Time since the event had a minor effect on recall. Based on the findings, several suggestions for emergency training are made. PMID:24325239

Estimating dynamics of heavily fluctuating radar responses: a land clutter application and experimental results  

NASA Astrophysics Data System (ADS)

The strength of radar response varies considerably. In this regard, the dynamic range of most receivers is not sufficient enough to operate optimally. Due to this fact, radar signal may represent only a fraction of the real backscattering phenomena. One way to solve the problem is to use automatic gain control (AGC). It helps to prevent the saturation of responses but inflicts performance degradation on subsequent radar signal processing. The same problem with dynamic range exists in other fields of sensing as well. For example, a solution in digital photography is to use various exposure times to determine the most appropriate one for the current conditions. In this paper, a corresponding approach is proposed for analyzing radar responses. The method requires measurements of a selected area to be performed with various gains, and the resulting dynamic ranges should overlap partially. The use of a linear receiver ensures that both the power and the coherent phase statistics can be extracted from the data. Using the proposed approach, a few distributions derived from extensive land clutter recordings from Finnish landscape are presented.

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.

Derivation of Theoretical Formulas and an Investigation on Measured Results of Grounding Electrode Transient Responses  

NASA Astrophysics Data System (ADS)

This paper has derived analytical formulas of a voltage and a current on a grounding electrode by adopting a simple model circuit composed of R, L and C elements. Based on the formulas, its transient characteristic is discussed, and approximate formulas of the surge impedance and the propagation velocity are proposed. Also, this paper summarizes measured results of transient responses on grounding electrodes with horizontal and vertical arrangements. The characteristics of the measured results are estimated based on the analytical formulas derived in the paper. It becomes clear that most of the measured results show either an inductive or a resistive characteristic as far as the investigated cases in the paper are concerned. In the capacitive case, the transient resistance is not much different from the steady-state resistance. Also, it has been shown that measured steady-state resistances agree well with those evaluated by Sunde's formula for a horizontal electrode.

T-dependent antigen response (TDAR) tests: meta-analysis of results generated across multiple laboratories.  

PubMed

The primary T-cell-dependent antibody response (TDAR) to antigens is widely used as a functional test in immunotoxicology. TDAR assays can be performed using different antigens, e.g., sheep red blood cells (SRBC) and keyhole limpet hemocyanin (KLH) are presently utilized by different laboratories. The purpose of this study was to apply meta-analysis to compare data from several laboratories using these antigens, in two strains of rats, by multiple routes of immunization and with different primary TDAR assay formats. Although limitations imposed by the scale of the data set and the need to convert some data to an ordinal scale to allow comparisons restrict the scope and strength of the conclusions that can be drawn, the results of this study have shown that the two antigens in different assay formats give comparable results. Similarly, both antigens and assays formats showed the same pattern of response to strong immunotoxicants. These results indicate that standardizing the choice of antigen in TDAR assays may not be critical in the evaluation of potential immunotoxicity. PMID:18958725

ABCB1 variation and treatment response in AIDS patients: initial results of the Henan cohort.  

PubMed

HIV/AIDS has the highest mortality among infectious diseases in China. In ongoing efforts to alleviate this crisis, the national government has placed great emphasis on efforts in Henan province where HIV-infected former plasma donors in the 1990s contributed to AIDS becoming a public health crisis. Concomitant with a national initiative focusing the use of pharmacogenetics for the better prediction of treatment response, we studied genetic variants with known pharmacokinetic phenotypes in a set of 298 HAART-treated (highly active antiretroviral therapy) patients infected with HIV from the Henan cohort. We measured the association of response to treatment, assessed as changes in CD4+ T cell counts after antiretroviral therapy, of five polymorphisms in four genes (CYP2B6, ABCB1/MDR1, ABCG2, and ABCC4) in which variation has been suggested to affect the pharmacokinetics of drugs commonly employed to treat HIV/AIDS. We show that genotyping for ABCB1 variations (rs1045642 and rs2032582) may help predict HIV treatment response. We found variations in this gene have a significant association with outcome as measured by CD4+ T cell counts in a discovery subset (N= 197; odds ratio (OR) = 1.58; 95% CI 1.02-2.45), these results were confirmed in a validation subset of the cohort (N = 78; OR= 2.81; 95% CI 1.32-5.96). Exploratory analysis suggests that this effect may be specific to NVP (nevirapine) or 3TC (lamivudine) response. This publication represents the first genetic analysis in a continuing effort to study and assist the patients in a very large, unique, and historically significant HIV-AIDS cohort. Genotyping of AIDS patients for ABCB1 variation may help predict outcome and potentially could help guide treatment strategies. PMID:23372834

American society of nephrology quiz and questionnaire 2013: electrolyte and Acid-base.  

PubMed

The Nephrology Quiz and Questionnaire (NQ&Q) remains an extremely popular session for attendees of the annual meeting of the American Society of Nephrology. As in past years, the conference hall was overflowing with interested audience members. Topics covered by expert discussants included electrolyte and acid-base disorders, glomerular disease, ESRD/dialysis, and transplantation. Complex cases representing each of these categories along with single-best-answer questions were prepared by a panel of experts. Prior to the meeting, program directors of United States nephrology training programs answered questions through an Internet-based questionnaire. A new addition to the NQ&Q was participation in the questionnaire by nephrology fellows. To review the process, members of the audience test their knowledge and judgment on a series of case-oriented questions prepared and discussed by experts. Their answers are compared in real time using audience response devices with the answers of nephrology fellows and training program directors. The correct and incorrect answers are then briefly discussed after the audience responses, and the results of the questionnaire are displayed. This article recapitulates the session and reproduces its educational value for the readers of CJASN. Enjoy the clinical cases and expert discussions. PMID:24558051

Questionnaire Based Assessment of Risk Factors for Primary Biliary Cirrhosis  

PubMed Central

Background Primary Biliary Cirrhosis is a cholestatic liver disease characterized by immune-mediated destruction of bile ducts. Its pathogenesis is largely unknown, although complex interactions between environment and genetic predisposition are proposed. Aims Identify disease risk factors using a detailed patient questionnaire and compare study findings to 3 published reports. Methods Questionnaire data were prospectively collected from 522 cases and 616 controls of the Mayo Clinic Primary Biliary Cirrhosis Genetic Epidemiology Registry. Case and control responses were compared using logistic regression, adjusting for recruitment age, sex, and education level. Results Cases reported ever regularly smoking cigarettes more frequently than controls (P < 0.001). History of urinary tract infection (UTI) was similar between groups; however, cases reported multiple UTIs more commonly than controls (P < 0.001). Frequency of other autoimmune disease was higher in cases than controls (P < 0.001). As well, prevalence of primary biliary cirrhosis among first-degree relatives was higher in case families than control families (P < 0.001). Conclusions Our study confirms prior reported risk factors associated with disease risk. Given the potential importance of gene and environment interactions, further examination of environmental risk factors considering genetic background may provide new insight into primary biliary cirrhosis pathogenesis.

Preimplantation genetic diagnosis (PGD) influences adrenal development and response to cold stress in resulting mice.  

PubMed

Preimplantation genetic diagnosis (PGD) has gained widespread application in clinical medicine and hence the health of PGD offspring needs to be systematically assessed. Given the critical role of the stress response in growth and health, assessments of the development and function of the stress system might help to clarify the health outcomes of PGD. In this study, we constructed a PGD-conceived mouse model and used naturally conceived mice as controls; we used this model to evaluate the potential effect of PGD procedures on the stress system of the offspring. Serum and tissues of stress organs, namely the hypothalamus, locus coeruleus and adrenal gland, were collected from 5-week-old mice in the basal state or after cold stress. The serum levels of stress-related hormones and the structural and functional indices of the stress organs were then examined. In the basal state, ultrastructural abnormalities and low expression of genes involved in steroid hormone synthesis were found in the adrenals of the PGD mice, which had low corticosterone and high epinephrine levels compared with those of control mice. After acute cold stress, the PGD mice continued to show structural and glucocorticoid secretion abnormalities resulting in a late response to the environmental change. Thus, our study indicates that PGD manipulations affect adrenal development, result in structural and functional abnormalities of the adrenals in the offspring and influence their reactivity and adaptability to cold stress.

Comparison of experimental results and calculated detector responses for PBFA II thermal source experiments  

SciTech Connect

We performed experiments using proton beams to heat foam-filled cylinders on the Particle Beam Fusion Acceleration II. Preliminary analysis of these diagnostic results provides reasonable agreement between prediction and experiment. The diagnostic package allowed us to benchmark target response as well as diagnose driver performance. Soft x-ray images, both time and space resolved, and the results of broadband spectral measurements on bolometers and x-ray diodes provide qualitative agreement with LASNEX predictions of target features such as Au motion and soft x-ray emission profile. The analysis is consistent with a total beam deposition of 40--50 kJ and power depositions of approximately 180 TW/g. Estimates of target motion confirm the ability of the foam to retard wall motion.

Reliability of a health questionnaire among women with brain injury.  

PubMed

Research with respect to traumatic brain injury (TBI) has identified differential health outcomes by gender. However, despite this, a lack of research exists regarding the impact of TBI on specific health-related issues for women. This study investigated rater agreement of a health questionnaire developed to identify health concerns among women with TBI. Thirteen women with moderate to severe brain injury completed the questionnaire twice (1 week apart) and provided feedback regarding content and ease of use. The questionnaire measures areas of menses, conception, menopause, thyroid function, and change in participation in activities after brain injury. Kappa coefficients and percentage agreement were generated to determine levels of agreement of participant responses between the two sessions. Kappa coefficients ranged from .21 to 1.00, with the highest agreement for items requiring concrete responses (e.g., yes/no) and the lowest with items requiring more subjective answers. Percentage agreement ranged from 58% to 100%. Participants rated the utility of the questionnaire as high (73%-100%). This questionnaire proved to be a reliable and useful method to gather information regarding health in women with TBI. By identifying health issues early, diagnostic and treatment intervention may be delivered in a timelier and effective manner. Further psychometric testing is required to ensure the validity of responses. PMID:21796031

Translation and validation of the German version of the Bournemouth questionnaire for low back pain  

PubMed Central

Background Finding the best outcome measures for research and quality assurance purposes in terms of validity, sensitivity to change, length and ease of completion is crucial. The Bournemouth questionnaire for neck pain patients was recently translated and validated into German and found to be more sensitive to change than other commonly used questionnaires. However, the low back pain version is not yet available in German. Therefore the purpose of this study was to translate and validate the Bournemouth Questionnaire (BQ) for low back pain (LBP) into German. Methods The translation was done in 4 steps, translated and back-translated by two independent people and adapted and approved by an expert committee. Face validity was then done by 30 people who checked the questionnaire for comprehension. Test-retest reliability (reproducibility) was tested using 30 stable back pain patients. Internal consistency was tested using 108 low back patients. External construct validity, external longitudinal validity and responsiveness was tested against the German versions of the Oswestry Disability Index (ODI) and the SF-36 questionnaire using 108 patients from 5 different chiropractic clinics. Results The BQ showed high test-retest reliability (ICC?>?0.91) for all items and strong internal consistency (Cronbachs alpha?=?0.86 at baseline and 0.94 at 4 weeks). The BQ demonstrated good external construct and longitudinal construct validity with established measures. The effect sizes of the BQ were high and comparable with established measures. External construct validity and external longitudinal construct validity showed significant correlation for all 7 scales of the BQ with the relevant scales of the other questionnaires with one exception. External responsiveness results showed higher effect sizes for the BQ items and total score indicating better sensitivity to change than the compared measures. Conclusion The BQ for LBP was successfully translated and adapted into German. It was successfully tested for validity, consistency, and responsiveness against the German versions of the ODI and the SF-36. It is shorter, covers more domains than the ODI and is more sensitive to change than the other questionnaires.

Does amplitude scaling of ground motion records result in biased nonlinear structural drift responses?  

USGS Publications Warehouse

Limitations of the existing earthquake ground motion database lead to scaling of records to obtain seismograms consistent with a ground motion target for structural design and evaluation. In the engineering seismology community, acceptable limits for 'legitimate' scaling vary from one (no scaling allowed) to 10 or more. The concerns expressed by detractors of scaling are mostly based on the knowledge of, for example, differences in ground motion characteristics for different earthquake magnitude-distance (Mw-Rclose) scenarios, and much less on their effects on structures. At the other end of the spectrum, proponents have demonstrated that scaling is not only legitimate but also useful for assessing structural response statistics for Mw-Rclose scenarios. Their studies, however, have not investigated more recent purposes of scaling and have not always drawn conclusions for a wide spectrum of structural vibration periods and strengths. This article investigates whether scaling of records randomly selected from an Mw-Rclose bin (or range) to a target fundamental-mode spectral acceleration (Sa) level introduces bias in the expected nonlinear structural drift response of both single-degree-of-freedom oscillators and one multi-degree-of-freedom building. The bias is quantified relative to unscaled records from the target Mw-Rclose bin that are 'naturally' at the target Sa level. We consider scaling of records from the target Mw-Rclose bin and from other Mw-Rclose bins. The results demonstrate that scaling can indeed introduce a bias that, for the most part, ca be explained by differences between the elastic response spectra of the scaled versus unscaled records.

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

The Attitudes to Ageing Questionnaire: Mokken Scaling Analysis  

PubMed Central

Background Hierarchical scales are useful in understanding the structure of underlying latent traits in many questionnaires. The Attitudes to Ageing Questionnaire (AAQ) explored the attitudes to ageing of older people themselves, and originally described three distinct subscales: (1) Psychosocial Loss (2) Physical Change and (3) Psychological Growth. This study aimed to use Mokken analysis, a method of Item Response Theory, to test for hierarchies within the AAQ and to explore how these relate to underlying latent traits. Methods Participants in a longitudinal cohort study, the Lothian Birth Cohort 1936, completed a cross-sectional postal survey. Data from 802 participants were analysed using Mokken Scaling analysis. These results were compared with factor analysis using exploratory structural equation modelling. Results Participants were 51.6% male, mean age 74.0 years (SD 0.28). Three scales were identified from 18 of the 24 items: two weak Mokken scales and one moderate Mokken scale. (1) ‘Vitality’ contained a combination of items from all three previously determined factors of the AAQ, with a hierarchy from physical to psychosocial; (2) ‘Legacy’ contained items exclusively from the Psychological Growth scale, with a hierarchy from individual contributions to passing things on; (3) ‘Exclusion’ contained items from the Psychosocial Loss scale, with a hierarchy from general to specific instances. All of the scales were reliable and statistically significant with ‘Legacy’ showing invariant item ordering. The scales correlate as expected with personality, anxiety and depression. Exploratory SEM mostly confirmed the original factor structure. Conclusions The concurrent use of factor analysis and Mokken scaling provides additional information about the AAQ. The previously-described factor structure is mostly confirmed. Mokken scaling identifies a new factor relating to vitality, and a hierarchy of responses within three separate scales, referring to vitality, legacy and exclusion. This shows what older people themselves consider important regarding their own ageing.

The response of microalgae to photooxidative stress resulting from high light exposure is a well-studied phenomenon. However, direct analyses of photosystem II (PSII) D1 protein (the main target of photoinhibition) in diatoms are scarce. In this study, the response of the diatom model species Phaeodactylum tricornutum to short-term exposure to high light was examined and the levels of D1 protein determined immunochemically. Low light (LL) acclimated cells (40 µmol photons m(-2) s(-1)) subjected to high light (HL, 1,250 µmol photons m(-2) s(-1)) showed rapid induction of non-photochemical quenching (NPQ) and ca. 20-fold increase in diatoxanthin (DT) concentration. This resulted from the conversion of diadinoxanthin (DD) to DT through the activation of the DD-cycle. D1 protein levels under LL decreased about 30% after 1 h of the addition of lincomycin (LINC), a chloroplast protein synthesis inhibitor, showing significant D1 degradation and repair under low irradiance. Exposure to HL lead to a 3.2-fold increase in D1 degradation rate, whereas average D1 repair rate was 1.3-x higher under HL than LL, leading to decreased levels of D1 protein under HL. There were significant effects of both HL and LINC on P. tricornutum maximum quantum yield of PSII (F(v)/F(m)), showing a reduction of active PSII reaction centres. Partial recovery of F(v)/F(m) in the dark demonstrates the photosynthetic resilience of this diatom to changes in the light regime. P. tricornutum showed high allocation of total protein to D1 and an active D1-repair cycle to limit photoinhibition. PMID:22675519

Validating an alternate version of the chewing function questionnaire in partially dentate patients  

PubMed Central

Background The aim of this study was to investigate the dimensionality, reliability, and validity of an alternate version of the chewing function questionnaire in partially dentate patients in Japan. Methods Subjects were partially dentate patients who attended the prosthodontic clinic at Tokyo Medical and Dental University (N = 491, 71% women, mean age (± SD): 63.0 ± 11.5 years). The questionnaire asked each subject to rate his or her ability to chew 20 common Japanese foods. For each individual, responses were combined to yield a chewing function summary score, with higher scores indicating better self-reported chewing ability. We used exploratory factor analysis to investigate the scores' dimensionality. For validity assessment, we computed the correlations between the chewing function score and oral health-related quality of life (OHRQoL, as measured by the Japanese 14-item Oral Health Impact Profile (OHIP-14)) Internal consistency of scores and test-retest reliability were investigated by asking a subset of subjects (N = 62) to complete the questionnaire twice, 2 weeks apart. Results Exploratory factor analysis provided some evidence that self-reported chewing ability can be characterized by a summary score as the original authors suggest. Support for the validity of chewing function scores using the alternate version of the questionnaire was derived from correlations with OHIP-14 scores (r = -0.46, 95% confidence interval (CI): -0.53 to -0.39); thus, better chewing ability was associated with less impaired OHRQoL. Internal consistency was 'satisfactory,' with a Cronbach's alpha of 0.90 (lower limit of 95% CI: 0.89). The test-retest reliability was 'good,' with an intraclass correlation coefficient of 0.69 (95% CI: 0.56 to 0.82). Conclusion The alternate version of the chewing function questionnaire can be used as a stand-alone instrument because of the demonstrated reliability and validity of scores obtained using the questionnaire in partially dentate patients.

Comparison of a video questionnaire with the IUATLD written questionnaire for measuring asthma prevalence.  

PubMed

A video questionnaire (VQ) for measuring asthma prevalence in adolescents was assessed for repeatability and validity in relation to bronchial hyperresponsiveness (BHR) (PD20 less than or equal to 7.8 mumol methacholine). Comparison was also made with a standard, self completed written questionnaire (SQ), based on the IUATLD Bronchial Symptoms Questionnaire, which included five questions seeking comparable data to those in the VQ. Both the VQ and SQ were administered to 707 schoolchildren (13-16 years), in whom English was the primary language. One hundred and six randomly selected children subsequently underwent bronchial challenge to methacholine. Both the sensitivity and specificity for BHR were higher for a combination of three or more positive responses to the VQ (0.73 and 0.88), than to the SQ (0.63 and 0.82), although these differences were not statistically significant (P = 0.24). When administered again after a two week interval, the VQ had a significantly higher (P = 0.03) coefficient of repeatability (0.79) than the SQ (0.50). We conclude that the VQ is a valid and reliable method of determining asthma prevalence, and propose that by providing data relatively free from biases due to language, culture, literacy or interviewing techniques it may be particularly useful when comparing asthma prevalence and severity in different populations.

Planned implementations of ePrescribing systems in NHS hospitals in England: a questionnaire study  

PubMed Central

Objectives To describe the plans of English NHS hospitals to implement ePrescribing systems. Design and setting Questionnaire-based survey of attendees of the National ePrescribing Forum. Participants A piloted questionnaire was distributed to all NHS and non-NHS hospital-based attendees. The questionnaire enquired about any completed or planned implementation of ePrescribing systems, the specific systems of interest, and functionality they offered. Main outcome measures Estimate of the number of NHS Trusts planning to implement ePrescribing systems. Results Ninety-one of the 166 questionnaires distributed to NHS hospital-based staff were completed and returned. Of those, six were incomplete, resulting in a total usable response rate of 51% (n = 85). Eighty-two percent (n = 46) of the 56 Trusts represented at the Forum were either ‘thinking of implementing’ or ‘currently implementing’ an ePrescribing system, such as Ascribe (13%, n = 7) and JAC (20%, n = 11). Forty percent (n = 22) of respondents specified other systems, including those procured by NHS Connecting for Health e.g. RiO, Lorenzo and Cerner. Knowledge support, decision support and computerized links to other elements of patients’ individual care records were the functionalities of greatest interest. Conclusion There is considerable reported interest and activity in implementing ePrescribing systems in hospitals across England. Whether such developments have the desired impact on improving the safety of prescribing is however, yet to be determined.

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.

Salix response to different flow regimes in controlled experiments: first results  

NASA Astrophysics Data System (ADS)

Dams and water management for hydropower production, agriculture and other human activities alter the natural flow regime of rivers. The new river hydrograph components depend on the type of impoundment and the policy of regulation but such a different flow regime will likely affect the riparian environment. The main challenge in order to define sustainable flow releases is to quantify hydrological effects in terms of geomorphology and ecosystem response. A considerable lack of knowledge still affects the link hydrology-ecology and inadequate flow rules (e.g., minimal or residual flows) are consequently still widespread: further research in this direction is urgently required. We present an experiment, which aims to investigate the effects of different water stage regimes on riparian vegetation (salix Viminalis cuttings) development in a temperate region (Switzerland). This work describes the installation setup, together with the first results concerning the first of the two scheduled seasons of campaign. Sixty Salix cuttings were planted in non-cohesive sandy-gravel sediment within 1 meter tall plastic pots installed outside in the EPFL campus. After grouping them in three batteries, the water level within them has been varying following three river regimes simulated by adjusting the water level within the pots by means of an automatic hydraulic system. The three water level regimes reproduce a natural flow regime, a minimum residual flow policy, which only conserves peaks during flooding conditions, and an artificial regime conserving only low frequencies (e.g., seasonality) of the natural dynamic. The natural flow regime of the first battery has been applied for two months to the entire system; the three regimes above said started in June 2012. This triggered a plant response transitory regime, which we monitored by measuring plant growth, soil and atmospheric variables. Particularly, measures concern with branches development leaves photosynthesis and fluorescence, together with pictures of each plant. Sap flow was measured for thirty cuttings using a time resolution of thirty minutes, whereas psychrometers measuring the water potential were sampling data every fifteen minutes. Soil moisture and meteo data have also been collected as essential drivers of plant response: these data as well as sap flow measurements can be later compared to a similar field installation along Thur River (Switzerland). After the first season of measurement, in 2012, part of the cuttings have been carefully removed and further analyzed as far as the below ground biomass is concerned. Strong differences in terms of stress and growth performances were observed in correspondence of the transitional phase, following the alterations of the natural flow regime. A later adjustment in the roots distribution allowed survivors to re-sprout and to withstand new conditions.

Different stress modalities result in distinct steroid hormone responses by male rats.  

PubMed

Since both paradoxical sleep deprivation (PSD) and stress alter male reproductive function, the purpose of the present study was to examine the influence of PSD and other stressors (restraint, electrical footshock, cold and forced swimming, N = 10 per group) on steroid hormones in adult Wistar male rats. Rats were submitted to chronic stress for four days. The stressors (footshock, cold and forced swimming) were applied twice a day, for periods of 1 h at 9:00 and 16:00 h. Restrained animals were maintained in plastic cylinders for 22 h/day whereas PSD was continuous. Hormone determination was measured by chemiluminescent enzyme immunoassay (testosterone), competitive immunoassay (progesterone) and by radioimmunoassay (corticosterone, estradiol, estrone). The findings indicate that PSD (13.7 ng/dl), footshock (31.7 ng/dl) and cold (35.2 ng/dl) led to lower testosterone levels compared to the swimming (370.4 ng/dl) and control (371.4 ng/dl) groups. However, progesterone levels were elevated in the footshock (4.5 ng/ml) and PSD (5.4 ng/ml) groups compared to control (1.6 ng/ml), swimming (1.1 ng/ml), cold (2.3 ng/ml), and restrained (1.2 ng/ml) animals. Estrone and estradiol levels were reduced in the PSD, footshock and restraint groups compared to the control, swimming and cold groups. A significant increase in corticosterone levels was found only in the PSD (299.8 ng/ml) and footshock (169.6 ng/ml) groups. These changes may be thought to be the full steroidal response to stress of significant intensity. Thus, the data suggest that different stress modalities result in distinct steroid hormone responses, with PSD and footshock being the most similar. PMID:15264021

Vessel noise affects beaked whale behavior: results of a dedicated acoustic response study.  

PubMed

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.

Design of psychosocial factors questionnaires: a systematic measurement approach  

PubMed Central

Background Evaluation of psychosocial factors requires instruments that measure dynamic complexities. This study explains the design of a set of questionnaires to evaluate work and non-work psychosocial risk factors for stress-related illnesses. Methods The measurement model was based on a review of literature. Content validity was performed by experts and cognitive interviews. Pilot testing was carried out with a convenience sample of 132 workers. Cronbach’s alpha evaluated internal consistency and concurrent validity was estimated by Spearman correlation coefficients. Results Three questionnaires were constructed to evaluate exposure to work and non-work risk factors. Content validity improved the questionnaires coherence with the measurement model. Internal consistency was adequate (?=0.85–0.95). Concurrent validity resulted in moderate correlations of psychosocial factors with stress symptoms. Conclusions Questionnaires´ content reflected a wide spectrum of psychosocial factors sources. Cognitive interviews improved understanding of questions and dimensions. The structure of the measurement model was confirmed.

Watershed Responses to Changes In Mercury Loading: Results from the Terrestrial Aspects of the METAALICUS Project  

NASA Astrophysics Data System (ADS)

The METAALICUS project is a whole-ecosystem experiment specifically designed to quantify the magnitude and timing of the watershed response to a change in mercury (Hg) loading. A decade ago, when the US and many other countries began to consider Hg-specific emission regulations, many doubted the effectiveness of such actions since terrestrial soils and aquatic sediments were already ubiquitously contaminated, and would potentially sustain mercury loading to aquatic indefinitely. To address this question, a multi-national team of scientists was formed to devise a whole-ecosystem, Hg-dosing study, whereby Hg would be deliberately added to an entire watershed - The Mercury Experiment to Assess Atmospheric Loadings in Canada and the US (METAALICUS) project, conducted at the Experimental Lakes Area (ELA), northwestern Ontario, Canada. Whole-ecosystem manipulation studies have a distinct advantage over small-scale (lab scale) studies, in that all the ecosystem components, natural processes and complexities within watersheds are accounted for. This paper focuses on the terrestrial (upland forest and wetland) aspects of METAALICUS project, with particular emphasis on assessing the long-term response to a change in Hg loading. A very unique aspect of the METAALICUS project called for the use of three different stable isotopes to be applied to the lake, forests and wetland, respectively. This experimental approach not only allowed for the direct observation of responses (time and space) to changes in loading, but also provides never before realized resolution of pathways and processes of mercury in a watershed. Mercury additions to the terrestrial components of the watershed were initiated in 2001 and continued through 2006, at a rate of about 5x measured current atmospheric deposition. Since this time, METAALICUS has become a mercury reduction experiment, and thus we have been monitoring of the response to a Hg load cessation. During the loading phase of the project, the majority of the terrestrially applied Hg isotopes were distributed approximately equally among three major compartments: soils, plants (tree canopy and ground vegetation), and losses to emissions from soil and plant surfaces. Much less (about 1%) isotope was measured in runoff that flowed into the downstream lake. With each successive annual dose the isotope pool in soils steadily increased, while the forest canopy and emission fluxes pools had comparatively low carryover from year to year. Within two years of loading cessation, isotope concentrations in canopy and emission fluxes were negligible and about half of the total isotope load was found in soils. Isotope concentrations in runoff gradually increased during the loading phase, and continued to increase for 1-2 years after loading ceased, suggesting significant translocation from compartments above the forest floor. Three years subsequent to cessation, isotope concentrations in soils have remained steady, and generally reflect the Hg abundance of the overall soil pool. Models calibrated to these results will be very useful for scenario testing to evaluate long-term recovery of lakes with significant watershed Hg contributions.

Developing the concept of family involvement and the alienation questionnaire in the context of psychiatric care.  

PubMed

Research shows that family members of people with a mental illness often experience a lack of involvement in the psychiatric care of their relative. An interpretation of the findings of these studies raises the question of whether the family members' experience of not being involved can be conceptualized in terms of alienation towards mental health services from their encounter with psychiatric care. In order to explore this possibility, the Family Involvement and Alienation Questionnaire (FIAQ) was constructed, guided by relevant theoretical frameworks and empirical research. The content validity of the questionnaire was evaluated by two groups of experienced researchers who had sound knowledge of the theoretical frameworks used. Validity based on the response process was evaluated by the parents of people with mental illness. The reliability of the questionnaire was evaluated by a test-retest design with a group of 15 family members. The data were analyzed by a non-parametric statistical method. The results of the validity and reliability evaluations showed that of the 46 original items in the questionnaire, 28 would be useful in exploring the concept of family involvement and alienation in the context of psychiatric care. Further, minor modifications could make the FIAQ useful in exploring these concepts in other settings. PMID:19128291

Evaluating the organisational climate in Italian public healthcare institutions by means of a questionnaire  

PubMed Central

Background By means of the ICONAS project, the Healthcare Agency of an Italian Region developed, and used a standardised questionnaire to quantify the organisational climate. The aims of the project were (a) to investigate whether the healthcare institutions were interested in measuring climate, (b) to estimate the range of applicability and reliability of the instrument, (c) to analyse the dimensions of climate among healthcare personnel, (d) to assess the differences among employees with different contractual positions. Methods The anonymous questionnaire containing 50 items, each with a scale from 1 to 10, was offered to the healthcare organisations, to be compiled during ad hoc meetings. The data were sent to the central project coordinator. The differences between highly specialised staff (mostly physicians) and other employees were assessed after descriptive statistical analysis of the single items. Both Principal Component Analysis and Factor Analysis were used. Results Ten healthcare organisations agreed to partecipate. The questionnaire was completed by 8691 employees out of 13202. The mean value of organisational climate was 4.79 (range 1–10). There were significant differences among single items and between the 2 groups of employees. Multivariate methods showed: (a) one principal component explained > 40% of the variance, (b) 7 factors summarised the data. Conclusion Italian healthcare institutions are interested in assessing organisational phenomena, especially after the reforms of the nineties. The instrument was found to be applicable and suitable for measuring organisational climate. Administration of the questionnaire leads to an acceptable response rate. Climate can be discribed by means of 7 underlying dimensions.

On some results on response observation of liquid storage tanks to natural earthquakes  

SciTech Connect

This article deals with some results of analysis on response of three liquid storage tanks in Chiba Field Station, Institute of Industrial Science, 50 km east of Tokyo. The first storage tank was completed in 1973, and now three tanks are installed in the station. They include a 20 m/sup 3/, 4 m diameter cylindrical steel rigid wall tank, a 54 m/sup 3/, 4 m diameter cylindrical steel thin wall tank, and a 60 m/sup 3/, 6 m X 4 m X 3 mH rectangular FRP panel-type storage on a rack. The maximum ground acceleration in the period of observation was approximately 90 Gal, and the ground displacement 8 mm. One of the most important conclusions of their study is that the amplification factor in acceleration phase is very cleary decreasing according to the input acceleration level. This is quite evident in the FRP panel type storage tank. Also, amplification factors vary according to individual earthquake characteristics at the higher input level. Some buckling type damage was observed on the wall of the thin wall cylindrical tank, Type number 2, this summer. The mechanism has not be clarified yet. The authors' findings including the above mentioned are useful to improve the design practice of such types of liquid storage tanks.

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

Scale items were derived from responses to semi-structured clinical interviews with patients who were awaiting breast biopsy. Internal consistency and test-retest reliability data are reported, as well as correlations with the Marlowe-Crowne, the Spielberger State-Trait Personality Inventory, the Eysenck Personality Questionnaire and the Bortner Type A Behavior Scale. Although intended for use with breast cancer patients this scale is envisaged to have wider application to other clinical populations. PMID:6620206

The human response to artificial gravity in a weightless environment: Results from the Neurolab centrifugation experiments  

NASA Astrophysics Data System (ADS)

On Earth, afferent otolith activity encodes head tilt with respect to gravity, as well as head linear acceleration. The vector sum of head acceleration and gravity, termed gravito-inertial acceleration (GIA), is used by the vestibular system to generate the perception of vertical, ocular counter-rolling (OCR), and vertical or roll components of nystagmus, which orient the axis of eye velocity towards alignment with the GIA. Head tilt is not sensed by the otoliths in microgravity, but the otoliths are still activated by translation. It has therefore been proposed that the brain reinterprets tilt-related otolith information as translation during space flight. During the 1998 Neurolab mission, 4 astronauts were exposed to inter-aural (IA) and body vertical (Z-axis) centripetal accelerations of 0.5 and 1-g by rotation in an off-axis centrifuge. During rotation, binocular 3D eye movements were measured using a video technique with the subject in darkness and while viewing an optokinetic stimulus. On Earth, 1-g centrifugation tilts the GIA 45° with respect to the head, and pre-flight perception of roll tilt was 35°. By flight day 5, all astronauts perceived ~90° of roll tilt in response to a constant 1-g IA linear acceleration. This tilt angle was under-reported early in flight, and over-estimated on return to Earth, possibly due to adaptation of otolith and/or somatosensory function during transition to the new gravitational states. Tilt perception was proportionally lower during 0.5-g centrifugation, both pre-flight (20°) and in-flight (46°). Similar results were obtained for pitch tilt perception during Z-axis centrifugation. The magnitude of OCR in response to the GIA during IA centrifugation was unchanged in microgravity, and was proportional to the centripetal acceleration. This suggests that both OCR and roll tilt perception are strongly dependent on the magnitude of IA linear acceleration, as in microgravity there is no body vertical (Z-axis) linear acceleration. The axis of eye velocity during both horizontal optokinetic nystagmus and angular acceleration in darkness tended to align with the GIA, as on Earth. In space, low frequency otolith information is not reinterpreted as translation, and constant 1-g linear acceleration is sensed as being equivalent to gravity. .

General practice postal surveys: a questionnaire too far?  

PubMed Central

A primary care led NHS, driven by evidence based practice, needs to build on a firm foundation of research in primary care. As researchers are making increasing use of questionnaire surveys to assess general practitioners' views and attitudes, so response rates to questionnaire surveys among general practitioners are dropping. The reasons include lack of perceived relevance of the research and lack of information and feedback about it, and researchers need to be more aware of the realities of everyday practice. Approaches that might reverse this trend include monitoring all research activities going on in an area to ensure that practices are not overused, giving general practitioners incentives to participate, and improving the relevance of research and the quality of questionnaires.

Athletes' assessment of the coach--the coach evaluation questionnaire.  

PubMed

The purpose of this study was to provide an assessment tool to judge coaching performance that was appropriate for completion by athletes. The questionnaire underwent a variety of developmental stages. In its final form, it contained 36 items. The tool was shown to be a valid, reliable, and standardized questionnaire. It demonstrated discriminability and provoked honest, accurate responding in subjects. The test was capable of providing immediate feedback to coaches seeking information about athletes' perceptions of their coaching performance. Responses on the developed scale were weighted to reflect the desirability of the coaching characteristics of a good coach. The questionnaire provides a total score which can be interpreted by the coach as a measure of how much of an "ideal" coach exists in him/her. PMID:4053263

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.

Modeling and experimental results of low-background extrinsic double-injection IR detector response  

NASA Astrophysics Data System (ADS)

Bias-dependent response of an extrinsic double-injection IR detector under irradiation from extrinsic and intrinsic responsivity spectral ranges was obtained analytically and through numerical modeling. The model includes the transient response and generation-recombination noise as well. It is shown that a great increase in current responsivity (by orders of magnitude) without essential change in detectivity can take place in the range of extrinsic responsivity for detectors on semiconductor materials with long-lifetime minority charge carriers if double-injection photodiodes are made on them instead photoconductive detectors. Field dependence of the lifetimes and mobilities of charge carriers essentially influences detector characteristics especially in the voltage range where the drift length of majority carriers is greater than the distance between the contacts. The model developed is in good agreement with experimental data obtained for n-Si:Cd, p-Ge:Au, and Ge:Hg diodes, as well as for diamond detectors of radiations. A BLIP-detection responsivity of about 2000 A/W (for a wavelength of 10 micrometers) for Ge:Hg diodes has been reached in a frequency range of 500 Hz under a background of 6 x 1011 cm-2s-1 at a temperature of 20 K. Possibilities of optimization of detector performance are discussed. Extrinsic double-injection photodiodes and other detectors of radiations with internal gain based on double injection are reasonable to use in the systems liable to strong disturbance action, in particular to vibrations, because high responsivity can ensure higher resistance to interference.

Seismic Response of a Sedimentary Basin: Preliminary Results from Strong Motion Downhole Array in Taipei Basin  

NASA Astrophysics Data System (ADS)

The Strong Motion Downhole Array (SMDA) is an array of 32 triggered strong motion broadband seismometers located at eight sites in Taipei Basin. Each site features three to five co-located three-component accelerometers--one at the surface and an additional two to four each down independent boreholes. Located in the center of Taipei Basin is Taipei City and the Taipei metropolitan area, the capital of Taiwan and home to more than 7 million residents. Taipei Basin is in a major seismic hazard area and is prone to frequent large earthquakes producing strong ground motion. This unique three-dimension seismic array presents new frontiers for seismic research in Taiwan and, along with it, new challenges. Frequency-dependent and site-specific amplification of seismic waves from depth to surface has been observed: preliminary results indicate that the top few tens of meters of sediment--not the entire thickness--are responsible for significant frequency-dependent amplification; amplitudes of seismic waves at the surface may be as much as seven times that at depth. Dominant amplification frequencies are interpreted as quarter-wavelength constructive interference between the surface and major interfaces in the sediments. Using surface stations with known orientation as a reference, borehole seismometer orientations in these data--which are unknown, and some of which vary considerably from event to event--have been determined using several methods. After low-pass filtering the strong motion data, iteratively rotating the two horizontal components from an individual borehole station and cross-correlating them with that from a co-located surface station has proven to be very effective. In cases where the iterative cross-correlation method does not provide a good fit, rotating both surface and borehole stations to a common axis of maximum seismic energy provides an alternative approach. The orientation-offset of a borehole station relative to the surface station may be estimated by iteratively rotating the horizontal components of both and calculating the time-integral of the amplitude squared of each component; the difference in orientation between the maximum at the surface and at depth indicates the difference in orientation of the seismometers. After the horizontal orientations of borehole seismometers are correctly resolved, these data can be used in various scientific studies. Up-going and reflected down-going shear waves can be clearly identified, providing an excellent dataset for the study of interval velocity and seismic Q, localized shear wave splitting, and anisotropy. Further refinement of the geophysical structure of Taipei Basin and Northern Taiwan is also possible by combining data from the SMDA with that from the large array of surface stations maintained by the Central Weather Bureau.

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.

Do mental skills make champions? Examining the discriminant function of the psychological characteristics of developing excellence questionnaire.  

PubMed

The ability to successfully develop to the highest levels in sport is dependent on a range of variables, not least an individual's ability to cope with the various challenges of development. Psychological Characteristics of Developing Excellence (PCDEs) include both the trait characteristics and the state-deployed skills that have been shown to play a crucial role in the realisation of potential. Psychological characteristics of developing excellence equip aspiring elites with the mental skills, attitudes, and emotions to cope with the challenges of the development pathway, as well as underpinning their capacity to make the most of their innate abilities. The Psychological Characteristics of Developing Excellence Questionnaire (PCDEQ) was designed to assess the possession and deployment of these characteristics. The purpose of this paper was to examine the ability of the Psychological Characteristics of Developing Excellence Questionnaire to effectively discriminate between good and poor developers based on their current possession and deployment of psychological characteristics of developing excellence. Two hundred and eighty-five athletes (n = 192 team athletes; n = 93 individual athletes) completed the Psychological Characteristics of Developing Excellence Questionnaire. Results from the discriminant function analysis suggest that the Psychological Characteristics of Developing Excellence Questionnaire correctly classifies between 67% and 75% of athletes based on their responses. The Psychological Characteristics of Developing Excellence Questionnaire can be used as a formative assessment tool to direct training programmes by identifying weaknesses in psychological characteristics of developing excellence and incorporating specific training to address these weaknesses in advance of developmental challenges.

The ARSQ: The Athletes' Received Support Questionnaire.  

PubMed

To address calls for context-specific measurement of social support, this article reports the development of the Athletes' Received Support Questionnaire (ARSQ) and demonstrates initial evidence for its validity. Across four studies there was support for a four-dimensional structure reflecting emotional, esteem, informational, and tangible received support. There was also support for unidimensional and higher-order models. Further, Study 3 provided some support for convergent validity, with significant correlations between the corresponding dimensions of the ARSQ and the Inventory of Socially Supportive Behaviors. Study 4 provided evidence for the nomological validity of the ARSQ. Emotional and esteem support significantly predicted self-confidence and positive affect, and tangible support significantly moderated the relationship between stress and negative affect. Collectively, these results provide initial evidence for the validity of the ARSQ, and offer researchers flexibility to adopt either a multidimensional or aggregated approach to measuring received support.

The Drug Effects Questionnaire: Psychometric Support across Three Drug Types  

PubMed Central

Rationale The Drug Effects Questionnaire (DEQ) is widely used in studies of acute subjective response (SR) to a variety of substances, but the format of the DEQ varies widely across studies, and details of its psychometric properties are lacking. Thus, the field would benefit from demonstrating the reliability and validity of the DEQ for use across multiple substances. Objective The current study evaluated the psychometric properties of several variations of DEQ items, which assessed the extent to which participants (1) feel any substance effect(s), (2) feel high, (3) like the effects, (4) dislike the effects, and (5) want more of the substance using 100mm Visual Analog Scales. Methods DEQ data from three placebo-controlled studies were analyzed to examine SR to amphetamine, nicotine, and alcohol. We evaluated the internal structure of the DEQ for use with each substance as well as relationships between scale items, measures of similar constructs, and substance-related behaviors. Results Results provided preliminary psychometric support for items assessing each DEQ construct (FEEL, HIGH, DISLIKE, LIKE, and MORE). Conclusions Based on the study results, we identify several common limitations of extant variants of the DEQ and recommend an improved version of the measure. The simplicity and brevity of the DEQ combined with its promising psychometric properties support its use in future SR research across a variety of substances.

NASA Technical Reports Server (NTRS)

Under NASA's In-Space Propulsion/Aerocapture Program, ARA conducted arc-jet and thermal-radiation ablation test series in 2003 for advanced development, characterization, and response modeling of SRAM-20, SRAM-17, SRAM-14, and PhenCarb-20 ablators. Testing was focused on the future Titan Explorer mission. Convective heating rates (CW) were as high as 153 W/sq cm in the IHF and radiation rates were 100 W/sq cm in the Solar Tower Facility. The ablators showed good performance in the radiation environment without spallation, which was initially a concern, but they also showed higher in-depth temperatures when compared to analytical predictions based on arc-jet thermal-ablation response models. More testing in 2003 is planned in both of these facility to generate a sufficient data base for Titan TPS engineering.

Leptin-responsive GABAergic neurons regulate fertility through pathways that result in reduced kisspeptinergic tone.  

PubMed

The adipocyte-derived hormone leptin plays a critical role in the central transmission of energy balance to modulate reproductive function. However, the neurocircuitry underlying this interaction remains elusive, in part due to incomplete knowledge of first-order leptin-responsive neurons. To address this gap, we explored the contribution of predominantly inhibitory (GABAergic) neurons versus excitatory (glutamatergic) neurons in the female mouse by selective ablation of the leptin receptor in each neuronal population: Vgat-Cre;Lepr(lox/lox) and Vglut2-Cre;Lepr(lox/lox) mice, respectively. Female Vgat-Cre;Lepr(lox/lox) but not Vglut2-Cre;Lepr(lox/lox) mice were obese. Vgat-Cre;Lepr(lox/lox) mice had delayed or absent vaginal opening, persistent diestrus, and atrophic reproductive tracts with absent corpora lutea. In contrast, Vglut2-Cre;Lepr(lox/lox) females exhibited reproductive maturation and function comparable to Lepr(lox/lox) control mice. Intracerebroventricular administration of kisspeptin-10 to Vgat-Cre;Lepr(lox/lox) female mice elicited robust gonadotropin responses, suggesting normal gonadotropin-releasing hormone neuronal and gonadotrope function. However, adult ovariectomized Vgat-Cre;Lepr(lox/lox) mice displayed significantly reduced levels of Kiss1 (but not Tac2) mRNA in the arcuate nucleus, and a reduced compensatory luteinizing hormone increase compared with control animals. Estradiol replacement after ovariectomy inhibited gonadotropin release to a similar extent in both groups. These animals also exhibited a compromised positive feedback response to sex steroids, as shown by significantly lower Kiss1 mRNA levels in the AVPV, compared with Lepr(lox/lox) mice. We conclude that leptin-responsive GABAergic neurons, but not glutamatergic neurons, act as metabolic sensors to regulate fertility, at least in part through modulatory effects on kisspeptin neurons.

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.

Trypanosomiasis-Induced B Cell Apoptosis Results in Loss of Protective Anti-Parasite Antibody Responses and Abolishment of Vaccine-Induced Memory Responses  

PubMed Central

African trypanosomes of the Trypanosoma brucei species are extra-cellular parasites that cause human African trypanosomiasis (HAT) as well as infections in game animals and livestock. Trypanosomes are known to evade the immune response of their mammalian host by continuous antigenic variation of their surface coat. Here, we aim to demonstrate that in addition, trypanosomes (i) cause the loss of various B cell populations, (ii) disable the hosts' capacity to raise a long-lasting specific protective anti-parasite antibody response, and (iii) abrogate vaccine-induced protective response to a non-related human pathogen such as Bordetella pertussis. Using a mouse model for T. brucei, various B cell populations were analyzed by FACS at different time points of infection. The results show that during early onset of a T. brucei infection, spleen remodeling results in the rapid loss of the IgM+ marginal zone (IgM+MZ) B cell population characterized as B220+IgMHighIgDInt CD21HighCD23LowCD1d+CD138?. These cells, when isolated during the first peak of infection, stained positive for Annexin V and had increased caspase-3 enzyme activity. Elevated caspase-3 mRNA levels coincided with decreased mRNA levels of the anti-apoptotic Bcl-2 protein and BAFF receptor (BAFF-R), indicating the onset of apoptosis. Moreover, affected B cells became unresponsive to stimulation by BCR cross-linking with anti-IgM Fab fragments. In vivo, infection-induced loss of IgM+ B cells coincided with the disappearance of protective variant-specific T-independent IgM responses, rendering the host rapidly susceptible to re-challenge with previously encountered parasites. Finally, using the well-established human diphtheria, tetanus, and B. pertussis (DTPa) vaccination model in mice, we show that T. brucei infections abrogate vaccine-induced protective responses to a non-related pathogen such as B. pertussis. Infections with T. brucei parasites result in the rapid loss of T–cell independent IgM+MZ B cells that are normally functioning as the primary immune barrier against blood-borne pathogens. In addition, ongoing trypanosome infections results in the rapid loss of B cell responsiveness and prevent the induction of protective memory responses. Finally, trypanosome infections disable the host's capacity to recall vaccine-induced memory responses against non-related pathogens. In particular, these last results call for detailed studies of the effect of HAT on memory recall responses in humans, prior to the planning of any mass vaccination campaign in HAT endemic areas.

Validation of the Turkish version of the quality of recovery-40 questionnaire  

PubMed Central

Background The Quality of Recovery-40 questionnaire (QoR-40) is a self-rated questionnaire used to assess the postoperative recovery quality and health status of patients in the early stages following surgery; however, there is no Turkish version of the QoR-40. The aim of this study was to assess the reliability, validity, and responsiveness of the Turkish version of the QoR-40 (QoR-40 T). Methods After the approval of the ethics committee, a total of 137 patients completed the questionnaire during the preoperative period, on the third day, and one month after surgery. The quality of life was evaluated by using a health-related quality of life questionnaire (Short-Form Health Survey-36; SF-36) on the third day and one month after surgery. Reliability, feasibility, and validity were assessed to validate the QoR-40 T. Results The Cronbach’s alpha of the global QoR-40 T on the third day after surgery was 0.936. A positive moderate correlation was obtained between the physical comfort, emotional state, physical independence, and pain dimensions of the QoR-40 T and the physical component summary, mental health, physical functioning, and bodily pain subscales of the SF-36 on the third day after surgery, respectively (physical comfort - physical component summary, ??=?0.292, p?=?0.001; emotional state - mental health, ??=?0.252, p?=?0.003; physical independence - physical functioning, ??=?0.340, p?responsive mean of the total QoR-40 T was 0.62. Conclusions The QoR-40 T showed satisfactory reliability and validity in evaluating the quality of recovery after surgery in the Turkish population.

Detecting exacerbations using the Clinical COPD Questionnaire  

PubMed Central

Background Early treatment of COPD exacerbations has shown to be important. Despite a non-negligible negative impact on health related quality of life, a large proportion of these episodes is not reported (no change in treatment). Little is known whether (low burden) strategies are able to capture these unreported exacerbations. Methods The Clinical COPD Questionnaire (CCQ) is a short questionnaire with great evaluative properties in measuring health status. The current explorative study evaluates the discriminative properties of weekly CCQ assessment in detecting exacerbations. Results In a multicentre prospective cohort study, 121 patients, age 67.4 ± 10.5 years, FEV1 47.7 ± 18.5% pred were followed for 6 weeks by daily diary card recording and weekly CCQ assessment. Weeks were retrospectively labeled as stable or exacerbation (onset) weeks using the Anthonisen symptom diary-card algorithm. Change in CCQ total scores are significantly higher in exacerbation-onset weeks, 0.35 ± 0.69 compared to -0.04 ± 0.37 in stable weeks (p < 0.001). Performance of the ? CCQ total score discriminating between stable and exacerbation onset weeks was sufficient (area under the ROC curve 0.75). At a cut off point of 0.2, sensitivity was 62.5 (50.3-73.4), specificity 82.0 (79.3-84.4), and a positive and negative predictive value of 43.5 (35.0-51.0) and 90.8 (87.8-93.5), respectively. Using this cut off point, 22 (out of 38) unreported exacerbations were detected while 39 stable patients would have been false positively 'contacted'. Conclusions Weekly CCQ assessment is a promising, low burden method to detect unreported exacerbations. Further research is needed to validate discriminative performance and practical implications of the CCQ in detecting exacerbations in daily care.

The Persian version of the Chronic Pain Acceptance Questionnaire.  

PubMed

Research on the role of acceptance in adjustment to persisting pain has been facilitated by the development of the Chronic Pain Acceptance Questionnaire (CPAQ). However, the CPAQ has not yet been validated amongst Iranian patients with chronic pain. To examine the psychometric properties of the Persian version of the CPAQ (P-CPAQ), 245 Persian-speaking chronic pain patients completed a battery of questionnaires, including: the P-CPAQ, a Pain Self-Efficacy Questionnaire, a slightly modified Roland and Morris Disability Questionnaire, the Catastrophizing Scale of the Coping Strategies Questionnaire, the Depression and Anxiety Scales of the Depression Anxiety And Stress Scale-21 and the Pain-Related Interference and Pain Intensity Scales of the Multidimensional Pain Inventory. Furthermore, to evaluate the reliability of the P-CPAQ, the measure was completed by 24 chronic pain patients, on two occasions that are 2 weeks apart. The results of the principal component analysis and confirmatory factor analysis yielded a two-factor solution. Furthermore, the reliability and construct validity of the P-CPAQ were confirmed. In general, consistent with studies in other countries, the results of the present study indicate that pain acceptance plays an important role in adjustment to chronic pain regardless of cultural and language differences between countries.

Monitoring the results of Canada/U.S.A. acid rain control programs: some lake responses.  

PubMed

Aquatic acidification by deposition of airborne pollutants emerged as an environmental issue in southeastern Canada during the 1970s. Drawing information from the extensive research and monitoring programs, a sequence of issue assessments demonstrated the necessity of reducing the anthropogenic emissions of acidifying pollutants, particularly sulphur dioxide (SO2). The 1991 Canada-U.S. Air Quality Agreement (AQA) was negotiated to reduce North American SO2 emissions by approximately 40% relative to 1980 levels by 2010, and at present, both countries have reduced emissions beyond their AQA commitment. In response to reduced SO2 emissions, atmospheric deposition of sulphate (SO4(2-)) and SO4(2-) concentrations in many lakes have declined, particularly in south-central Ontario and southern Québec. Sulphate deposition still exceeds aquatic critical loads throughout southeastern Canada however. Increasing pH or alkalinity (commonly deemed 'recovery') has been observed in only some lakes. Several biogeochemical factors have intervened to modify the lake chemistry response to reduced SO4(2-) input, notably release of stored SO4(2-) from wetlands following periods of drought and reduction in the export of base cations from terrestrial soils. Three examples from Ontario are presented to illustrate these responses. Significant increases in pH and alkalinity have been observed in many lakes in the Sudbury area of Ontario due to the large reductions in local SO2 emissions; 'early-stage' biological recovery is evident in these lakes. An integrated assessment model predicts that AQA emission reductions will not be sufficient to promote widespread chemical or biological recovery of Canadian lakes. Monitoring and modeling are mutually supporting assessment activities and both must continue. PMID:14570408

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

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. PMID:22690098

Psychometric properties of the Greek Diabetes Treatment Satisfaction Questionnaire  

PubMed Central

Objectives Measurement of treatment satisfaction in diabetes is important as it has been shown to be associated with positive outcomes, reduced disease cost and better health. The aim of this study was to assess the construct validity and internal consistency reliability of the Greek version of the Diabetes Treatment Satisfaction Questionnaire (DTSQ). Methods A sample of type II diabetes patients (N = 172) completed the DTSQ status version, the SF-36 health survey and also provided data regarding treatment method, clinical and socio-demographic status. Instrument structure, reliability (Cronbach's a) and construct validity (convergent, discriminative, concurrent and known-groups) were assessed. Results The DTSQ measurement properties were confirmed in the Greek version with confirmatory factor analysis (CFA). Scale reliability was high (Cronbach's a = 0.92). Item-scale internal consistency and discriminant validity were also good, exceeding the designated success criteria. Significant correlations were observed between DTSQ items/overall score and SF-36 scales/component scores, which were hypothesized to measure similar dimensions. Known groups' comparisons yielded consistent support of the construct validity of the instrument. Conclusions The instrument was well-accepted by the patients and its psychometric properties were similar to those reported in validation studies of other language versions. Further research, incorporating a longitudinal study design, is required for examining test-retest reliability and responsiveness of the instrument, which were not addressed in this study. Overall, the present results confirm that the DTSQ status version is a reasonable choice for measuring diabetes treatment satisfaction in Greece.

The Patient Health Questionnaire-9: Validation among Patients with Glaucoma  

PubMed Central

Background Depression and anxiety are two common normal responses to a chronic disease such as glaucoma. This study analysed the measurement properties of the depression screening instrument - Patient Health Questionnaire-9 (PHQ-9) using Rasch analysis to determine if it can be used as a measure. Methods In this hospital-based cross-sectional study, the PHQ-9 was administered to primary glaucoma adults attending a glaucoma clinic of a tertiary eye care centre, South India. All patients underwent a comprehensive clinical evaluation. Patient demographics and sub-type of glaucoma were abstracted from the medical record. Rasch analysis was used to investigate the following properties of the PHQ-9: behaviour of the response categories, measurement precision (assessed using person separation reliability, PSR; minimum recommended value 0.80), unidimensionality (assessed using item fit [0.7–1.3] and principal components analysis of residuals), and targeting. Results 198 patients (mean age ± standard deviation ?=?59.83±12.34 years; 67% male) were included. The native PHQ-9 did not fit the Rasch model. The response categories showed disordered thresholds which became ordered after category reorganization. Measurement precision was below acceptable limits (0.62) and targeting was sub-optimal (?1.27 logits). Four items misfit that were deleted iteratively following which a set of five items fit the Rasch model. However measurement precision failed to improve and targeting worsened further (?1.62 logits). Conclusions The PHQ-9, in its present form, provides suboptimal assessment of depression in patients with glaucoma in India. Therefore, there is a need to develop a new depression instrument for our glaucoma population. A superior strategy would be to use the item bank for depression but this will also need to be validated in glaucoma patients before deciding its utility.

An emotion-differentiated perspective on empathy with the emotion specific empathy questionnaire  

PubMed Central

Empathy refers to the thoughts and feelings of one individual in response to the observed (emotional) experiences of another individual. Empathy, however, can occur toward persons experiencing a variety of emotions, raising the question of whether or not empathy can be emotion specific. This paper discusses theoretical and empirical support for the emotion specificity of empathy. We present a new measure, the Emotion Specific Empathy questionnaire, which assesses affective and cognitive empathy for the six basic emotions. This paper presents the measure's psychometric qualities and demonstrates, through a series of models, the discriminant validity between emotion specific empathies suggesting empathy is emotion specific. Results and implications are discussed.

Responses ofBacillus subtilis spores to space environment: Results from experiments in space  

NASA Astrophysics Data System (ADS)

Onboard of several spacecrafts (Apollo 16, Spacelab 1, LDEF), spores ofBacillus subtilis were exposed to selected parameters of space, such as space vacuum, different spectral ranges of solar UV-radiation and cosmic rays, applied separately or in combination, and we have studied their survival and genetic changes after retrieval. The spores survive extended periods of time in space — up to several years —, if protected against the high influx of solar UV-radiation. Water desorption caused by the space vacuum leads to structural changes of the DNA; the consequences are an increased mutation frequency and altered photobiological properties of the spores. UV-effects, such as killing and mutagenesis, are augmented, if the spores are in space vacuum during irradiation. Vacuum-specific photoproducts which are different from the ‘spore photoproduct’ may cause the synergistic response of spores to the simultaneous action of UV and vacuum. The experiments provide an experimental test of certain steps of the panspermia hypothesis.

Fed State Prior to Hemorrhagic Shock and Polytrauma in a Porcine Model Results in Altered Liver Transcriptomic Response  

PubMed Central

Hemorrhagic shock is a leading cause of trauma-related mortality in both civilian and military settings. Resuscitation often results in reperfusion injury and survivors are susceptible to developing multiple organ failure (MOF). The impact of fed state on the overall response to shock and resuscitation has been explored in some murine models but few clinically relevant large animal models. We have previously used metabolomics to establish that the fed state results in a different metabolic response in the porcine liver following hemorrhagic shock and resuscitation. In this study, we used our clinically relevant model of hemorrhagic shock and polytrauma and the Illumina HiSeq platform to determine if the liver transcriptomic response is also altered with respect to fed state. Functional analysis of the response to shock and resuscitation confirmed several typical responses including carbohydrate metabolism, cytokine inflammation, decreased cholesterol synthesis, and apoptosis. Our findings also suggest that the fasting state, relative to a carbohydrate prefed state, displays decreased carbohydrate metabolism, increased cytoskeleton reorganization and decreased inflammation in response to hemorrhagic shock and reperfusion. Evidence suggests that this is a consequence of a shrunken, catabolic state of the liver cells which provides an anti-inflammatory condition that partially mitigates hepatocellar damage.

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.

Reciprocal regulation of protein kinase C isoforms results in differential cellular responsiveness.  

PubMed

Immunological homeostasis is often maintained by counteractive functions of two different cell types or two different receptors signaling through different intermediates in the same cell. One of these signaling intermediates is protein kinase C (PKC). Ten differentially regulated PKC isoforms are integral to receptor-triggered responses in different cells. So far, eight PKC isoforms are reported to be expressed in macrophages. Whether a single receptor differentially uses PKC isoforms to regulate counteractive effector functions has never been addressed. As CD40 is the only receptor characterized to trigger counteractive functions, we examined the relative role of PKC isoforms in the CD40-induced macrophage functions. We report that in BALB/c mouse macrophages, higher doses of CD40 stimulation induce optimum phosphorylation and translocation of PKC?, ?I, ?II, and ? whereas lower doses of CD40 stimulation activates PKC?, ?, and ?. Infection of macrophages with the protozoan parasite Leishmania major impairs PKC?, ?I, ?II, and ? isoforms but enhances PKC?, ?, and ? isoforms, suggesting a reciprocity among these PKC isoforms. Indeed, PKC?, ?I, ?II, and ? isoforms mediate CD40-induced p38MAPK phosphorylation, IL-12 expression, and Leishmania killing; PKC? and ?/? mediate ERK1/2 phosphorylation, IL-10 production, and parasite growth. Treatment of the susceptible BALB/c mice with the lentivirally expressed PKC?- or ?-specific short hairpin RNA significantly reduces the infection and reinstates host-protective IFN-?-dominated T cell response, defining the differential roles for PKC isoforms in immune homeostasis and novel PKC-targeted immunotherapeutic and parasite-derived immune evasion strategies.

The Radiation Response of Sarcomas by Histologic Subtypes: A Review With Special Emphasis Given to Results Achieved With Razoxane  

PubMed Central

Purpose. Relatively few results are available in the literature about the radiation response of unresectable sarcomas in relation to their histology. Therefore, an attempt was made to summarize the present situation. Materials and methods. This report is based on a review of the literature and the author's own experience. Adult-type soft tissue sarcomas, chondrosarcomas, and chordomas were analyzed. Radioresponse was mainly associated with the degree of tumor shrinkage, that is, objective responses. Histopathologic responses, that is, the degree of necrosis, are only discussed in relation to radiation treatment reports of soft tissue sarcomas as a group. Results. Radiation therapy alone leads to major responses in about 50% of lipo-, fibro-, leiomyo-, or chondrosarcomas. The response rate is less than 50% in malignant fibrous histiocytomas, synovial, neurogenic, and other rare soft tissue sarcomas. The response rates may increase up to 75% through the addition of radiosensitizers such as halogenated pyrimidines or razoxane, or by the use of high-LET irradiation. Angiosarcomas become clearly more responsive if biologicals, angiomodulating, and/or tubulin affinic substances are given together with radiation therapy. Razoxane is able to increase the duration and quality of responses even in difficult-to-treat tumors like chondrosarcomas or chordomas. Conclusions. The available data demonstrate that the radioresponsiveness of sarcomas is very variable and dependent on histology, kind of radiation, and various concomitantly given drugs. The rate of complete sustained remissions by radiation therapy alone or in combination with drugs is still far from satisfactory although progress has been made through the use of sensitizing agents.

Association of HLA-G 3' untranslated region polymorphisms with antibody response against Plasmodium falciparum antigens: preliminary results.  

PubMed

Host and Plasmodium interactions result in highly variable clinical phenotypes, partly explained by the nature and level of anti-malarial antibody response. Human leukocyte antigen (HLA)-G can create a tolerogenic environment, allowing parasites to escape from anti-malarial immunity. We performed a family-based association study encompassing 483 Sereer individuals (261 children and their parents), and reported two independent signals at the HLA-G 3' untranslated region associated with antibody response to specific Plasmodium falciparum blood stage antigens, previously associated with malaria protection: (i) +3010G together with +3142C with total IgG and IgG1 against GLURP and (ii) +3196G with IgG3 against MSP2. While these results require further investigation, they suggest for the first time a role of HLA-G in the regulation of humoral immune response in malaria. PMID:23745572

[Measuring patient satisfaction in integrated healthcare projects--a pilot study with a modified ZAP questionnaire].  

PubMed

Analysing the quality of integrated healthcare, as a new form of care, measurement of patient satisfaction becomes more and more important. However, there is a lack of standardised instruments of questionnaires for integrated network structures that could be used to measure and compare the satisfaction of participating insured persons. This gap should be closed by the study at hand, by arranging an exemplary measurement of satisfaction in the integrated care project OPTI-MuM. Because of the specific offers provided by the OPTI-MuM project, an existing questionnaire from the ambulatory sector had to be modified. A random sample of 1,000 insured individuals that have been enrolled in the project until now was interviewed. The response rate was 46.6%. In general, the survey respondents were very much satisfied with the provided integrated healthcare services. 75% of the respondents were 'very satisfied' or 'rather satisfied' with the range of services offered within the OPTI-MuM project. In addition, about 80% of the respondents would again participate in the project and recommend it. But the survey also demonstrated that there is potential for improving the provision of information. The study shows that the OPTI-MuM project is effective regarding the satisfaction of the participants. The questionnaire should be used for measuring satisfaction in comparable healthcare projects in order to enable a better classification of the results of this study. PMID:20441017

Rasch analysis of the Outcome Questionnaire with African Americans.  

PubMed

Effectively diagnosing African Americans' mental health with a single intake checklist has posed an unresolved challenge, as most intake checklists were developed from White perspectives. In this study, Rasch analysis was used to assess the psychometric characteristics of a common measure of clinical distress, the Outcome Questionnaire (OQ; Lambert, Lunnen, Umphress, Hansen, & Burlingame, 1994), for a sample of African American students split into a calibration and validation subsample. OQ subscales were first identified and were then held up under cross-validation with a second subsample. Rasch analysis of the OQ clearly indicated the measure was multidimensional among African American students with 2 subscales titled Well-Being and Psychological Distress. Our results also indicated appropriate response scale use, adequate person separation, strong stability across subsamples, and little differential item functioning. Moreover, our analysis showed items of the 2 subscales to be well-targeted for African American students. However, if subscales were to be revised for African American students, some items at the same logit position might be deleted and replaced with either very easy or more difficult items or with items at intermediate positions to extend and to fill in gaps in construct coverage. Implications for theory and research on multicultural mental health scales were discussed. PMID:23544393

Response of lead-acid batteries to chopper-controlled discharge: Preliminary results  

NASA Technical Reports Server (NTRS)

The preliminary results of simulated electric vehicle, chopper, speed controller discharge of a battery show energy output losses up to 25 percent compared to constant current discharges at the same average discharge current of 100 amperes. These energy losses are manifested as temperature rises during discharge, amounting to a two-fold increase for a 400-ampere pulse compared to the constant current case. Because of the potentially large energy inefficiency, the results suggest that electric vehicle battery/speed controller interaction must be carefully considered in vehicle design.

Evaluation of impairment of health related quality of life in asthma: development of a questionnaire for use in clinical trials.  

PubMed Central

BACKGROUND: In the past only physiological and clinical outcomes have been used to assess the effect of asthma interventions and the effect of the intervention on the lives of the patients has not been determined. The objective of this study was to assess health related impairment of quality of life in adult asthmatic patients and to develop a questionnaire for measuring quality of life in clinical trials in asthma. METHODS: Impairment of quality of life in adults with asthma was evaluated from structured interviews in which patients were asked to identify the parts of their daily lives affected by asthma. On the basis of these results, an asthma quality of life questionnaire was developed in an interviewer and self administered form and tested for comprehension and acceptability. A total of 150 adults with asthma and with a wide range of airway hyperresponsiveness were enrolled from previous clinical trials, local asthma clinics, and notices in the media. RESULTS: Areas of quality of life impairment included symptoms classically associated with asthma, responses to environmental stimuli, the need to avoid these stimuli, limitation of activities, and emotional dysfunction. Areas of impairment were similar across strata of airway hyperresponsiveness, age, and treatment requirements and between sexes, thus allowing a single questionnaire suitable for all adults with asthma to be developed. The questionnaire contains 32 items and takes 5-10 minutes to administer; in the pretesting it was shown to be acceptable to a wide range of patients. CONCLUSIONS: The questionnaire includes areas of quality of life impairment that are important to adult asthmatic patients. It has been designed to be responsive to within subject change and therefore may be used as a measure of outcome in clinical trials in asthma.

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.

Response of permafrost to projected climate change: Results from global offline model simulations with JSBACH  

NASA Astrophysics Data System (ADS)

Permafrost or perennially frozen ground is an important part of the terrestrial cryosphere; roughly one quarter of Earth's land surface is underlain by permafrost. As it is a thermal phenomenon, its characteristics are highly dependent on climatic factors. The impact of the currently observed warming, which is projected to persist during the coming decades due to anthropogenic CO2 input, certainly has effects for the vast permafrost areas of the high northern latitudes. The quantification of these effects, however, is scientifically still an open question. This is partly due to the complexity of the system, where several feedbacks are interacting between land and atmosphere, sometimes counterbalancing each other. Moreover, until recently, many global circulation models (GCMs) lacked the sufficient representation of permafrost physics in their land surface schemes. In order to assess the response of permafrost to projected climate change for the 21st century, the land surface scheme of the Max-Planck-Institute for Meteorology, JSBACH, has recently been equipped with the important physical processes for permafrost studies, and was driven globally with bias corrected climate data, thereby spanning a period from 1850 until 2100. The applied land surface scheme JSBACH now considers the effects of freezing and thawing of soil water for both energy and water cycles, thermal properties depending on soil water and ice contents, and soil moisture movement being influenced by the presence of soil ice. To address the uncertainty range arising through different greenhouse gas concentrations as well as through different climate realisations when using various climate models, combinations of two Representative Concentration Pathways (RCPs) and two GCMs were used as driving data. In order to focus only on the climatic impact on permafrost, effects due to feedbacks between climate and permafrost (namely via carbon fluxes between land and atmosphere) are excluded in the experiments. Differences between future time slices and today's climate are analysed. The effect in relevant variables, such as permafrost extent, depth of the Active Layer, ground temperature, and amount of soil carbon, is investigated. The experiments (as well as the development of JSBACH with respect to permafrost soil physics) are part of the European project PAGE21, where a focus is set on interactions between the changing climate and its impact on permafrost, especially for the 21st century.

Measuring physical activity among pregnant women using a structured one-week recall questionnaire: evidence for validity and reliability  

PubMed Central

Background Accurate measurement of the components of physical activity during pregnancy can aid in our understanding of the dose response relationships between physical activity and corresponding perinatal outcomes. The aim of this study was to develop and evaluate a one-week recall questionnaire to assess moderate to vigorous physical activity during pregnancy. Methods To assess concurrent-related validity, 177 pregnant women (median 18 weeks' gestation, interquartile range (IQR) 15 -23) kept a structured diary and wore an accelerometer (Actigraph) for one week. At the conclusion of the week, they completed the Pregnancy Infection and Nutrition 3 (PIN3) physical activity questionnaire over the telephone. To assess evidence for test-retest reliability, 109 pregnant women (median 19 weeks' gestation, IQR 18-27) completed the questionnaire twice over the telephone, within 48 hours apart, recalling the same two time periods. Spearman correlation coefficients (SCC) and intraclass correlation coefficients (ICC) were used to assess evidence for validity and reliability, respectively. Results Comparison of the questionnaire to the structured diary was moderate to substantial (SCC 0.47 to 0.69) for several measures of moderate or vigorous physical activity using either perceived or absolute intensity. Comparison of moderate to vigorous physical activity from the questionnaire (absolute intensity using MET-hours/week) to the accelerometer ranged from 0.12 to 0.23 using SCC for absolute intensity (MET-hours/week) and 0.28 to 0.34 using relative intensity (hours/week) (n = 177). Test-retest reliability was moderate to almost perfect for moderate to vigorous physical activity, with the ICC ranging from 0.56 to 0.82 for both perceived and absolute intensities. Conclusions The PIN3 one-week recall questionnaire assessed moderate to vigorous physical activity in the past week with evidence for reliability and validity.

Development and validation of the living with pulmonary hypertension questionnaire in pulmonary arterial hypertension patients  

PubMed Central

Background The Living with Pulmonary Hypertension questionnaire (LPH) was adapted from the Minnesota Living with Heart Failure Questionnaire for use in patients with pulmonary arterial hypertension (PAH). Study objectives were to confirm the face and content validity, to assess the structure and psychometric properties, and provide guidance for the interpretation of the LPH. Methods A qualitative interview study was conducted with PAH patients in the US (n=12), Germany (n=14) and France (n=12) to evaluate the face and content validity of the LPH. Psychometric validation was performed using blinded data from a double blind, Phase III, clinical trial (n=196). Validation analyses were performed on baseline and week 12 (visit 6/last visit) data and included evaluation of: item response distributions, quality of completion, construct validity, reliability, clinical validity and responsiveness. Analyses to provide an estimation of the Minimal Important Difference (MID) for the LPH scores were performed. Results Cognitive debriefing interviews with 38 PAH patients indicated that the most commonly reported PAH symptoms and impacts are covered by LPH items. Patients found the LPH questionnaire relevant and comprehensive to their experience. Some suggestions were made to enhance the face validity of the LPH. The content validity of the questionnaire was supported. Results of the psychometric validation analyses (n=190) indicated that the LPH Emotional and Physical scores met the criteria for convergent and discriminant validity; for the total score all but two items met the test for item convergent validity. Internal consistency reliability was demonstrated by Cronbach’s alpha values of >0.70 for all LPH scores. The LPH Physical and Total scores discriminated between World Health Organisation (WHO) Functional classes and 6 Minute walk test distances, indicating clinical validity and were also responsive to change in clinical severity, as measured by change in WHO functional class and Borg CR 10 Scale. Further investigation is required to confirm the responsiveness of the Emotional score. Estimation of MID using distribution-based methods indicated a change of 3 points for the sub-scales and 7 for the total score to be clinically meaningful. Conclusion The LPH is a valid and reliable instrument that meets FDA criteria.

Responses to Online GSTM1 Genetic Test Results among Smokers Related to Patients with Lung Cancer: A Pilot Study  

PubMed Central

Providing smokers with personal genetic test results indicating increased lung cancer risk may increase uptake of effective smoking cessation services. Using the internet may increase reach and enable real-time assessment of how people process genetic risk information away from the clinic setting. We therefore explored smokers' responses to Web-delivered GSTM1 genetic test results indicating higher or lower lung cancer risk. Participants were smokers (n = 44) biologically related to patients with newly diagnosed lung cancer. Measures were assessed at baseline, before and immediately after receipt of online genetic test results, and at 6-month follow-up. Outcomes included accurate comprehension of results, regret about being tested, cessation-related cognitions (e.g., perceived response efficacy), and uptake of free smoking cessation services (nicotine replacement therapy, printed self-help materials, telephone counseling sessions). Twenty-two “relative smokers” received a GSTM1-missing (higher risk) and 22 a GSTM1-present (lower risk) result. All relative smokers with GSTM1-missing results and 55% of those with GSTM1-present results accurately interpreted their results. No relative smokers regretted having taken the test. Relative smokers receiving GSTM1-missing results reported lower confidence that quitting could reduce lung cancer risk (perceived response efficacy) than those receiving GSTM1-present results. There were no other significant between-group differences. Uptake of smoking cessation services was high (e.g., 91% nicotine replacement therapy uptake). Genetic test results may not influence uptake of free smoking cessation services because of ceiling effects. Further research is needed to determine the risks and benefits of Web-based disclosure of genetic test results.

Validity and reliability of an occupational exposure questionnaire for parkinsonism in welders.  

PubMed

This study assessed the validity and test-retest reliability of a medical and occupational history questionnaire for workers performing welding in the shipyard industry. This self-report questionnaire was developed for an epidemiologic study of the risk of parkinsonism in welders. Validity participants recruited from three similar shipyards were asked to give consent for access to personnel files and complete the questionnaire. Responses on the questionnaire were compared with information extracted from personnel records. Reliability participants were recruited from the same shipyards and were asked to complete the questionnaire at two different times approximately 4 weeks apart. Percent agreement, kappa, intraclass correlation coefficient (ICC), and sensitivity and specificity were used as measures of validity and/or reliability. Personnel files were obtained for 101 of 143 participants (70%) in the validity study, and 56 of the 95 (58.9%) participants in the reliability study completed the retest of the questionnaire. Validity scores for items extracted from personnel files were high. Percent agreement for employment dates and job titles ranged from 83-100%, while ICC for start and stop dates ranged from 0.93-0.99. Sensitivity and specificity for current job title ranged from 0.5-1.0. Reliability scores for demographic, medical and health behavior items were mainly moderate or high, but ranged from 0.19 to 1.0. Most recent job/title items such as title, types of welding performed, and material used showed substantial to perfect agreement. Certain determinants of exposure such as days and hours per week exposed to welding fumes demonstrated mainly moderate agreement (kappa= 0.42-0.47, percent agreement 63-77%); however, mean days and hours reported did not differ between test and retest. The results of this study suggest that participants' self-report for job title and dates employed are valid compared with employer records. While kappa scores were low for some medical conditions and for caffeine consumption, high kappa scores for job title, dates worked, types of welding, and materials welded suggest participants generated reproducible answers important for occupational exposure assessment.

Validation of a questionnaire measuring the regulation of autonomic function  

PubMed Central

Background To broaden the range of outcomes that we can measure for patients undergoing treatment for oncological and other chronic conditions, we aimed to validate a questionnaire measuring self-reported autonomic regulation (aR), i.e. to characterise a subject's autonomic functioning by questions on sleeping and waking, vertigo, morningness-eveningness, thermoregulation, perspiration, bowel movements and digestion. Methods We administered the questionnaire to 440 participants (?: N = 316, ?: N = 124): 95 patients with breast cancer, 49 with colorectal cancer, 60 with diabetes mellitus, 39 with coronary heart disease, 28 with rheumatological conditions, 32 with Hashimoto's disease, 22 with multiple morbidities and 115 healthy people. We administered the questionnaire a second time to 50.2% of the participants. External convergence criteria included the German version of the Hospital Anxiety and Depression Scale (HADS-D), a short questionnaire on morningness-eveningness, the Herdecke Quality of Life Questionnaire (HLQ) and a short version questionnaire on self-regulation. Results A principal component analysis yielded a three dimensional 18-item inventory of aR. The subscales orthostatic-circulatory, rest/activity and digestive regulation had internal consistency (Cronbach-?: r? = 0.65 – 0.75) and test-retest reliability (rrt = 0.70 – 85). AR was negatively associated with anxiety, depression, and dysmenorrhoea but positively correlated to HLQ, self-regulation and in part to morningness (except digestive aR) (0.49 – 0.13, all p < 0.05). Conclusion An internal validation of the long-version scale of aR yielded consistent relationships with health versus illness, quality of life and personality. Further studies are required to clarify the issues of external validity, clinical and physiological relevance.

Validation of a Persian Version of Motorcycle Rider Behavior Questionnaire  

PubMed Central

In Iran, road traffic injuries are the first cause of burden of disease and motorcyclists are the most vulnerable road users. Elliot and colleagues developed the “Motorcycle Rider Behavior Questionnaire” (MRBQ), on the basis of Reason’s “Driver Behavior Questionnaire” (DBQ) in 2007. The purpose of this study was to assess the validity and reliability of a Persian version of MRBQ. The 43-item MRBQ was adapted to Persian according to translation-back translation method. The questionnaire was significantly revised after assessment of content validity. In the revised version, 10 items of original MRBQ were deleted and 15 new items were added. The revised MRBQ was used in a survey of 518 motorcyclists. To assess the construct validity of MRBQ, we used Buss-Perry Aggression questionnaire concurrently on all of the subjects. After three weeks, we carried out the retest study on 119 out of 518 subjects. The mean age of the subjects was 32.5 years (SD=8.8). All of the participants were male with mean of 9.3 years of motorcycle riding experience (SD=7.3). Principal Components Analysis (PCA) showed six subscales: “Speed Violations”, “Traffic Errors”, “Safety Violations”, “Traffic Violations”, “Stunts” and “Control Errors”, which accounted for 36.44% of total variance together. For each of these subscales, Cronbach’s Alpha was between 0.79 to 0.91. Intraclass Correlation Coefficient for six subscales and total questionnaire were from 0.73 to 0.91. There were significant correlations between MRBQ subscales and subscales of Buss-Perry aggression questionnaire. The results indicated that the 48-item Persian version of MRBQ is a suitable measure for studying motorcyclists’ behavior.

[New results on the linearity of the dose-response relationship of radiation-induced mutation].  

PubMed

Mutations induced by ionizing radiation in germ cells may affect future generations; mutations induced in somatic cells may damage the irradiated persons themselves, because radiation carcinogenesis is assumed to result from genetic damage induced in somatic cells. Since we are exposed mainly to low doses of ionizing radiation, both from natural and artificial sources, especially the dose dependence of radiation-induced mutations in the low-dose range is of interest. A review of recent studies on the induction of mutations by X-rays in human cells (in vitro) favors the hypothesis that in the low-dose range the dose dependence is linear, without a "threshold."

Exploratory factor analyses yielded evidence for a five-factor structure to the ICQ, with two factors that may be conceptually viewed as infant-oriented beliefs regarding infant crying (Attachment/Comfort and Crying as Communication) and three factors conceptually reflecting parent-oriented beliefs regarding infant crying (Minimization, Directive Control, and Spoiling). Each of the scales demonstrated strong internal consistency and was associated with concurrent measures of mothers’ causal attributions about emotional responses to infant crying. Predictive validity to observed maternal sensitivity at 6 months and mother-reported infant behavioral problems at one year was demonstrated. The importance of a questionnaire method to assess parents’ beliefs regarding infant crying in developmental research is discussed and future methodological directions are outlined.

Comparative Study of 2 Different Questionnaires in Japanese Patients: The Quality of Life and Utility Evaluation Survey Technology Questionnaire (QUEST) Versus the Frequency Scale for the Symptoms of Gastroesophageal Reflux Disease Questionnaire (FSSG)  

PubMed Central

Background/Aims The aim of this study was to examine the convenience of the quality of life and utility evaluation survey technology (QUEST) questionnaire and the frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) questionnaire as self-assessment diagnostic instrument. Methods This was a two-way crossover study conducted over 6 weeks from September 2010 to November 2010. The subjects were 60 consecutive patients admitted to the Hiratsuka city hospital with a gastrointestinal condition, regardless of the coexistence of heartburn. They were assigned to fill in both the QUEST and FSSG questionnaires in random order. We analyzed the time taken to complete the questionnaires, whether subjects asked any questions as they filled in the questionnaire, and the questionnaire scores. Results Comparison of the QUEST and the FSSG revealed significant differences in the completion time (196.5 vs. 97.5 seconds, respectively; P < 0.0001) and in whether subjects asked any questions (37 vs. 15 subjects, respectively; P < 0.0001). Completion time in QUEST scores of ? 4 was lower than < 4 (170.5 vs. 214.0 seconds, respectively; P = 0.022), and the QUEST score was significantly higher without questions than with question (3 vs. 1 points, respectively; P = 0.025). Conclusions This study revealed that the FSSG questionnaire may be easier for Japanese subjects to complete than the QUEST questionnaire.

The Manchester-Oxford Foot Questionnaire (MOXFQ)  

PubMed Central

Objectives The Manchester–Oxford Foot Questionnaire (MOXFQ) is a validated 16-item, patient-reported outcome measure for evaluating outcomes of foot or ankle surgery. The original development of the instrument identified three domains. This present study examined whether the three domains could legitimately be summed to provide a single summary index score. Methods The MOXFQ and Short-Form (SF)-36 were administered to 671 patients before surgery of the foot or ankle. Data from the three domains of the MOXFQ (pain, walking/standing and social interaction) were subjected to higher order factor analysis. Reliability and validity of the summary index score was assessed. Results The mean age of the participants was 52.8 years (sd 15.68; 18 to 89). Higher order principle components factor analysis produced one factor, accounting for 74.7% of the variance. The newly derived single index score was found to be internally reliable (? = 0.93) and valid, achieving at least moderate correlations (r ? 0.5, p < 0.001) with related (pain/function) domains of the SF-36. Conclusions Analyses indicated that data from the MOXFQ can be presented in summary form. The MOXFQ summary index score (MOXFQ-Index) provides an overall indication of the outcomes of foot and ankle surgery. Furthermore, the single index reduces the number of statistical comparisons, and hence the role of chance, when exploring MOXFQ data.

Stress Questionnaires and Stress Biomarkers during Pregnancy  

PubMed Central

Abstract Objective Both self-reported indicators of stress and hormones such as cortisol and corticotrophin-releasing hormone (CRH) have been examined in relation to preterm birth. Although these hormones have been interpreted as biomarkers of stress, it is unclear whether psychosocial measures are empirically associated with biomarkers of stress in pregnant women. Methods We analyzed data from 1,587 North Carolina pregnant women enrolled in the Pregnancy, Infection, and Nutrition study during 2000–2004 who provided at least one saliva sample for cortisol measurement or blood samples for CRH at 14–19 and 24–29 weeks' gestation. Cortisol measures were limited to those taken between 8 and 10 a.m. Perceived stress, state-trait anxiety, coping style, life events, social support, and pregnancy-specific anxiety were measured by questionnaires and interviews. Spearman correlations and multiple regressions were used to describe the relationship among the measures of stress. Results No correlations larger than r?=?0.15 were seen between reported psychosocial measures and cortisol or CRH. Women with demographic characteristics associated with poor pregnancy outcomes (unmarried, African-American, young, low pre-pregnancy body mass index) reported higher levels of stress but did not consistently have higher levels of stress hormones. Pre-eclampsia was associated with higher CRH, but not with higher cortisol. Conclusions The relationship between measurements of reported stress and biomarkers is not straightforward in large epidemiological studies of pregnancy.

Pregnancy in Multiple Sclerosis: A Questionnaire Study  

PubMed Central

Background Multiple sclerosis (MS) preferentially affects females at childbearing age. For this reason patients and treating physicians were frequently confronted with questions concerning family planning, pregnancy and birth. Objective The aim of this study was to evaluate the expertise about pregnancy related topics in multiple sclerosis of neurologists in private practice. Methods We developed a survey with 16 multiple choice questions about pregnancy related topics and sent it to neurologists in private practice in Berlin, Germany. Results 56 completed questionnaires were sent back. 54% of all questions were answered correctly, 21% of the questions were answered with “I don’t know”. Correct answers were more often given by physicians who treat more than 400 MS patients per year (p?=?0.001). Further positive associations were found for assumed relevance of the topic (p?=?0.002) and the degree of counseling (p<0.001). Conclusion To provide a comprehensive counseling, MS patients with desire for children should be counseled by physicians with a lot of experience in MS treatment.

The effect of morphology upon electrophysiological responses of retinal ganglion cells: simulation results.  

PubMed

Retinal ganglion cells (RGCs) display differences in their morphology and intrinsic electrophysiology. The goal of this study is to characterize the ionic currents that explain the behavior of ON and OFF RGCs and to explore if all morphological types of RGCs exhibit the phenomena described in electrophysiological data. We extend our previous single compartment cell models of ON and OFF RGCs to more biophysically realistic multicompartment cell models and investigate the effect of cell morphology on intrinsic electrophysiological properties. The membrane dynamics are described using the Hodgkin - Huxley type formalism. A subset of published patch-clamp data from isolated intact mouse retina is used to constrain the model and another subset is used to validate the model. Two hundred morphologically distinct ON and OFF RGCs are simulated with various densities of ionic currents in different morphological neuron compartments. Our model predicts that the differences between ON and OFF cells are explained by the presence of the low voltage activated calcium current in OFF cells and absence of such in ON cells. Our study shows through simulation that particular morphological types of RGCs are capable of exhibiting the full range of phenomena described in recent experiments. Comparisons of outputs from different cells indicate that the RGC morphologies that best describe recent experimental results are ones that have a larger ratio of soma to total surface area.

Stratospheric ozone response to sulfate geoengineering: Results from the Geoengineering Model Intercomparison Project (GeoMIP)  

NASA Astrophysics Data System (ADS)

with stratospheric sulfate aerosols has been proposed as a means of temporarily cooling the planet, alleviating some of the side effects of anthropogenic CO2 emissions. However, one of the known side effects of stratospheric injections of sulfate aerosols under present-day conditions is a general decrease in ozone concentrations. Here we present the results from two general circulation models and two coupled chemistry-climate models within the experiments G3 and G4 of the Geoengineering Model Intercomparison Project. On average, the models simulate in G4 an increase in sulfate aerosol surface area density similar to conditions a year after the Mount Pinatubo eruption and a decrease in globally averaged ozone by 1.1-2.1 DU (Dobson unit, 1 DU = 0.001 atm cm) during the central decade of the experiment (2040-2049). Enhanced heterogeneous chemistry on sulfate aerosols leads to an ozone increase in low and middle latitudes, whereas enhanced heterogeneous reactions in polar regions and increased tropical upwelling lead to a reduction of stratospheric ozone. The increase in UV-B radiation at the surface due to ozone depletion is offset by the screening due to the aerosols in the tropics and midlatitudes, while in polar regions the UV-B radiation is increased by 5% on average, with 12% peak increases during springtime. The contribution of ozone changes to the tropopause radiative forcing during 2040-2049 is found to be less than -0.1 W m-2. After 2050, because of decreasing ClOx concentrations, the suppression of the NOx cycle becomes more important than destruction of ozone by ClOx, causing an increase in total stratospheric ozone.

Responses to Positive Results from Suspicionless or Random Drug Tests in U.S. Public School Districts  

PubMed Central

Background Little is known about the context in which school-based suspicionless or random drug testing (SRDT) occurs. The primary purpose of the current study is to describe school districts’ responses to students’ first positive result in districts with SRDT programs. Methods Data were collected in spring 2005 from 1612 drug prevention coordinators in a nationally representative sample of 1922 school districts (83.9% response rate), of which 205 districts reported SRDT in high school grades. Results Respondents reported an array of consequences for students with an initial positive SRDT, including requiring parents or guardians to meet with school officials (88.4%), and requiring students to participate in an education, counseling, or treatment program (60.8%). However, some districts also reported consequences contraindicated by federal advisory guides, such as notifying law enforcement officials (45.1%) and suspending the student from an athletic team (65.0%) or from school (31.0%). Some respondents may have conflated their districts’ responses to for-cause and random tests. Districts generally had available key services for students testing positive, including professional counseling for substance use problems (87.3%) and referrals to counseling services (91.9%). Conclusions More understanding is needed of schools’ responses to students who test positive following the administration of SRDT, available advisory guides concerning best practices should be more effectively disseminated, and appropriate training and technical assistance should be available to schools with SRDTs.

Validation of the Korean Integrative Medicine Attitude Questionnaire (IMAQ)  

PubMed Central

Background To develop a Korean version of the Integrative Medicine Attitude Questionnaire (IMAQ) in order to evaluate physician attitudes toward integrative medicine/complementary and alternative medicine (CAM). Methods We developed a Korean IMAQ through careful translation of the 28-item questionnaire developed by Schmidt et al. A web-based survey was sent via email to 118 primary care physicians in Korea. The complete respose rate wasa 52.5%. The questionnaire's reliability and validity were verified using Cronbach's ?, factor analysis, and discriminant analysis. Results Although the Korean IMAQ exhibited excellent internal consistency, its validity was insufficient. Our results suggest that Western and Korean physicians may have different understandings of CAM and the concept of holism, as factor analysis showed that incorrectly classified items were mainly part of the holism conceptual domain. Furthermore, the sum of the items within the holism conceptual domain was not significantly different for physicians who had previously received CAM education. Conclusion This study developed and tested the first Korean IMAQ. We found that this version of the questionnaire lacks sufficient validity and requires further modification.

Concomitant activation and antigen uptake via human Dectin-1 results in potent antigen-specific CD8+ T cell responses  

PubMed Central

Dectin-1, a C-type lectin recognizing fungal and mycobacterial pathogens, can deliver intracellular signals that activate dendritic cells (DCs), resulting in initiation of immune responses and expansion of Th17 CD4+ T cell responses. Here, we studied the roles of human Dectin-1 (hDectin-1) expressed on DCs in the induction and activation of antigen-specific CD8+ T cell responses. We first generated an agonistic anti-hDectin-1 monoclonal antibody (mAb), which recognizes the hDectin-1 Glu143-Ile162 region. It bound to in vitro monocyte-derived DCs and to in vivo CD1c+CD1a+ dermal DCs, but not to epidermal Langerhans cells. Anti-hDectin-1-mediated DC activation resulted in upregulation of costimulatory molecules and secretion of multiple cytokines and chemokines in a Syk-dependent manner. DCs activated with the anti-hDectin-1 mAb could significantly enhance both neo and foreign antigen-specific CD8+ T cell responses by promoting both the expansion of CD8+ T cell and their functional activities. We further demonstrated that delivering antigens to DCs via hDectin-1 using anti-hDectin-1-antigen conjugates resulted in potent antigen-specific CD8+ T cell responses. Thus, hDectin-1 expressed on DCs can contribute to the induction and activation of cellular immunity against intracellular pathogens, such as mycobacteria, that are recognized by DCs via Dectin-1. Vaccines based on delivering antigens to DCs with an agonistic anti-hDectin-1 mAb could elicit CD8+ T cell-mediated immunity.

Development of a questionnaire to evaluate practitioners' confidence and knowledge in primary care in managing chronic kidney disease  

PubMed Central

Background In the UK, chronic disease, including chronic kidney disease (CKD) is largely managed in primary care. We developed a tool to assess practitioner confidence and knowledge in managing CKD compared to other chronic diseases. This questionnaire was part of a cluster randomised quality improvement interventions in chronic kidney disease (QICKD; ISRCTN56023731). Methods The questionnaire was developed by family physicians, primary care nurses, academics and renal specialists. We conducted three focus groups (n?=?7, 6, and 8) to refine the questionnaire using groups of general practitioners, practice nurses and trainees in general practice. We used paper based versions to develop the questionnaire and online surveys to test it. Practitioners in a group of volunteer, trial practices received the questionnaire twice. We measured its reliability using Cohen’s Kappa (K). Results The practitioners in the focus groups reached a consensus as to the key elements to include in the instrument. We achieved a 73.1% (n?=?57/78) initial response rate for our questionnaire; of these 57, 54 completed the questionnaire a second time. Family physicians made up the largest single group of respondents (47.4%, n?=?27). Initial response showed more female (64.9%, n?=?37) than male (35.1%, n?=?20) respondents. The reliability results from retesting showed that there was moderate agreement (k?>?0.4) on all questions; with many showing substantial agreement (k?>?0.6). There was substantial agreement in the questions about loop diuretics (k?=?0.608, CI 0.432-0.784, p?

Measuring the effects of online health information for patients: Item generation for an e-health impact questionnaire  

PubMed Central

Objective The internet is a valuable resource for accessing health information and support. We are developing an instrument to assess the effects of websites with experiential and factual health information. This study aimed to inform an item pool for the proposed questionnaire. Methods Items were informed through a review of relevant literature and secondary qualitative analysis of 99 narrative interviews relating to patient and carer experiences of health. Statements relating to identified themes were re-cast as questionnaire items and shown for review to an expert panel. Cognitive debrief interviews (n = 21) were used to assess items for face and content validity. Results Eighty-two generic items were identified following secondary qualitative analysis and expert review. Cognitive interviewing confirmed the questionnaire instructions, 62 items and the response options were acceptable to patients and carers. Conclusion Using a clear conceptual basis to inform item generation, 62 items have been identified as suitable to undergo further psychometric testing. Practice implications The final questionnaire will initially be used in a randomized controlled trial examining the effects of online patient's experiences. This will inform recommendations on the best way to present patients’ experiences within health information websites.

EULAR response criteria for polymyalgia rheumatica: results of an initiative of the European Collaborating Polymyalgia Rheumatica Group (subcommittee of ESCISIT)  

PubMed Central

Objective: To develop response criteria for polymyalgia rheumatica (PMR) for monitoring treatment and comparing alternative treatments regimens. Methods: 76 patients, mean (SD) age 68.7 (7.7) years, were enrolled. Corticosteroids, and non-steroidal anti-inflammatory drugs (NSAIDs) were the only drugs allowed during the observation period. Erythrocyte sedimentation rate (ESR), C reactive protein (CRP), ?2 globulin, serum iron, pain, physician's global assessment (PGA), morning stiffness (MST), muscle tenderness (MT), myalgia, and the elevation of upper limbs (EUL) were determined regularly. The daily corticosteroid and NSAID doses as the corticosteroid response time were recorded. To ensure evaluation of an adequate number of patients (n = 57) week 24 was chosen for final analysis. Results: ESR, CRP, ?2 globulin, pain, PGA, MST, myalgia, MT, and EUL showed significant improvement (p<0.0001) at week 24 compared with week 0. Multiple regression analysis showed that changes of ESR (p = 0.08), CRP (p = 0.41), ?2 globulin (p = 0.13), MST (p = 0.1), and MT (p = 0.07) were independent of pain, but myalgia (p<0.001) and EUL (p = 0.003) were pain dependent. Consequently, a core set of PMR response criteria, comprising ESR or CRP, pain, PGA, MST, and EUL was established. Assessment of treatment responses with this core set resulted in 90%, 70%, 50%, and 20% improvement in 31/57 (54%), 46/57 (81%), 51/57 (89%), and 54/57 (95%) of the patients, respectively. Conclusion: These PMR response criteria are a promising tool for better monitoring of disease activity and treatment in PMR. It is proposed that these criteria should be used in clinical trials in the near future to explore alternative treatment options for PMR.

Results of measurements of the response of a delta-doped CCD to neutral and charged particle beams  

NASA Astrophysics Data System (ADS)

We report the measurements of the response of a delta-doped Charge Coupled Device (CCD) in imaging mode to beams of charged and neutral particles. That is, the detector imaged the incident beam over its 1024 × 1024 pixels, integrating the number of particles counted in each pixel during the exposure period. In order to count individual particles the exposure time would have had to be reduced considerably compared to the typical ?5 s used in these studies. Our CCD thus operated in a different manner than do conventional particle detectors such as the CEM and MCP that normally are used in a particle counting mode. The measurements were carried out over an energy range from 0.8 to 30 keV. The species investigated include H, H +, He +, N +, N 2+, and Ar +. The energy and ion mass covered wider ranges than previous measurements for the CCD. The results of these measurements show, as in the case of the previous measurement, for a given ion the CCD response increases with energy and for a given particle energy the response decreases with increasing mass of the particle. These results are in agreement with predictions of the theory of the range of ions in solids. The results also show the possibility for the application of the delta doped CCD as a detector for low energy particle measurements for space plasma physics applications.

Questionnaire about psychology/disease correlation - II  

PubMed Central

Objective. To further evaluate the adequacy of the items in our questionnaire aimed at unraveling the possible correlations between psychological features and internal disorders. This paper is dedicated to the items exploring the individual’s interaction with other people. Method. The items are divided into several subdomains. For each subdomain, we have calculated the correlations between the items of the respective subdomain (inner associations) and with the items in other subdomains (outer associations) by means of chi square test or Fisher exact test as dictated by statistical reasons. We examined the answers from our first 10192 respondents. Results and conclusions. Many inter-item correlations are the consequence of higher or lesser degrees of synonymy. Those within a given subdomain confirm the adequate allocation of items. Those bridging different subdomains may point either to incorrect assignments, or to semantic inclusion relations. Other results are not explicable by semantic similarity, and probably reveal psychological subtleties, such as: most individuals have a sense of undeservedness when badly treated by other people; those easily hurt by insults and humiliations have a propensity to timidity and/or emotivity; the subjects who shun conflicts are more prone to persistent thoughts, brooding people are more sensitive and more prone to conflicts, injustice-indignant people frequently get into conflict although they declare to be bothered by dissent etc. But at the heart of all the PFs in the Interaction-with-other-people domain there seems to be the sense of being undervalued, which should probably be the key issue to be addressed by any therapeutic interventions for diseases psychoemotionally determined by disturbed interpersonal relationships. Abbreviations: PF = psychological feature; Chisq = chi-square; OdRa = odds ratio; OdRaCL = odds ratio confidence limits; ErrProb = probability of error

Occupant feedback questionnaire producing a fingerprint and a score  

SciTech Connect

In order to ensure that buildings and HVAC plans are truly for people and actually satisfy the occupants, it is necessary to obtain feedback from the occupants. This can be done by a novel questionnaire that produces a readily understandable fingerprint and score to indicate occupants' liking of their environments. The questionnaire uses a double-Likert section rating the liking and importance of up to 24 environmental, organizational, and human factors. To date it has been used primarily in U.K. offices, including modern deep-plan, naturally ventilated buildings. Comparison is made to previous results from 1,400 occupants in 12 offices that are air conditioned and naturally ventilated, where scores ranged from +17% (greatly liked by the occupants) to {minus}15% (greatly disliked). However, four U.K. offices with 1,300 occupants, which are discussed in detail, produced very low scores, {minus}14% to {minus}39%, the latter for a building with no windows. The fingerprints and scores were supported by an independent consultant's survey of the buildings and plant and also detailed factor analysis. The latter indicated that the 18 factors used in the questionnaire could be reduced to 5 general factors. The most important factors for the occupants for their ideal office were temperature, health, ventilation, and heating control, and the least important were the appearance of the building, distance to a window, humidity, and glare. It is proposed that this questionnaire is a useful management tool and suitable for use as a final commissioning tool.

Task-oriented evaluation of electronic medical records systems: development and validation of a questionnaire for physicians  

PubMed Central

Background Evaluation is a challenging but necessary part of the development cycle of clinical information systems like the electronic medical records (EMR) system. It is believed that such evaluations should include multiple perspectives, be comparative and employ both qualitative and quantitative methods. Self-administered questionnaires are frequently used as a quantitative evaluation method in medical informatics, but very few validated questionnaires address clinical use of EMR systems. Methods We have developed a task-oriented questionnaire for evaluating EMR systems from the clinician's perspective. The key feature of the questionnaire is a list of 24 general clinical tasks. It is applicable to physicians of most specialties and covers essential parts of their information-oriented work. The task list appears in two separate sections, about EMR use and task performance using the EMR, respectively. By combining these sections, the evaluator may estimate the potential impact of the EMR system on health care delivery. The results may also be compared across time, site or vendor. This paper describes the development, performance and validation of the questionnaire. Its performance is shown in two demonstration studies (n = 219 and 80). Its content is validated in an interview study (n = 10), and its reliability is investigated in a test-retest study (n = 37) and a scaling study (n = 31). Results In the interviews, the physicians found the general clinical tasks in the questionnaire relevant and comprehensible. The tasks were interpreted concordant to their definitions. However, the physicians found questions about tasks not explicitly or only partially supported by the EMR systems difficult to answer. The two demonstration studies provided unambiguous results and low percentages of missing responses. In addition, criterion validity was demonstrated for a majority of task-oriented questions. Their test-retest reliability was generally high, and the non-standard scale was found symmetric and ordinal. Conclusion This questionnaire is relevant for clinical work and EMR systems, provides reliable and interpretable results, and may be used as part of any evaluation effort involving the clinician's perspective of an EMR system.

Shortness of Breath with Daily Activities questionnaire: validation and responder thresholds in patients with chronic obstructive pulmonary disease  

PubMed Central

Objectives To test the reliability, validity and responsiveness of the 13-item Shortness of Breath with Daily Activities (SOBDA) questionnaire, and determine the threshold for response and minimal important difference (MID). Design 6?week, randomised, double-blind, placebo-controlled study. Setting 40 centres in the USA between 29 October 2009 and 1 July 2010. Primary and secondary outcome measures 547 patients with chronic obstructive pulmonary disease (COPD) were enrolled and 418 entered the 2-week run-in period. Data from the run-in period were collected to test internal consistency, test–retest reliability, convergent validity and known-groups validity of the SOBDA. Three hundred and sixty six patients were randomised 2:2:1 to fluticasone propionate/salmeterol 250/50?µg, salmeterol 50?µg or placebo, twice daily. Results from the SOBDA questionnaire, Patient Global Assessment of Change Question, modified Medical Research Council Dyspnoea Scale (mMRC), Clinician Global Impression of Dysponea Severity (CGI-S), Clinician Global Impression of Change Question and Chronic Respiratory Disease Questionnaire self-administered standardised version (CRQ-SAS) were evaluated; spirometry and safety parameters were measured. Study endpoints were selected to investigate the cross-sectional and longitudinal validity of the SOBDA questionnaire in relation to the clinical criteria. Results Internal consistency of the SOBDA questionnaire (Cronbach ?) was 0.89. Test–retest reliability (intraclass correlation) was 0.94. The SOBDA weekly scores correlated with the patient-reported and clinician-reported mMRC, CGI-S and CRQ-SAS dyspnoea domain scores (0.29, 0.24, 0.24 and –0.68, respectively). The SOBDA weekly scores differentiated between the responders and the non-responders as rated by the patients and the clinicians. Anchor-based and supportive distribution-based analyses produced a range of the potential values for the threshold for the responders and MID. Conclusions The 13-item SOBDA questionnaire is reliable, valid and responsive to change in patients with COPD. On using anchor-based methods, the proposed responder threshold shows a ?0.1 to ?0.2 score change. A specific threshold value will be identified as more data are generated from future clinical trials. Trial registration NCT00984659; GlaxoSmithKline study number: ASQ112989.

An assessment of basic pain knowledge and impact of pain education on Indian Anaesthesiologists - a pre and post questionnaire study  

PubMed Central

Background and Aim: Under-treatment of pain is a global phenomenon and the basic knowledge of pain amongst health care providers continues to be deficient. The aim of this study was to determine the basic prevalent knowledge of pain among Indian anaesthesiologists and the impact of a pain educational programme on their existing knowledge. Methods: A nine lectures pain continuing medical education (CME) program was conducted for 114 young anaesthesiologists. All delegates were given 21-item questionnaire in a pre and post-test design. The 69 paired responses were compared for individual questions using McNemar test and the overall improvement in knowledge was analysed using paired t-test. Results: The pre-test score for correct answers was 61.9%. The post-test score was 69.8% and this improvement was found to be statistically significant (P < 0.001). A significant improvement in perception was detected that ‘opioids usage was less likely to cause addiction’ (correct responses increased from 4.2 to 77.4%, P = 0.001). Conclusion: The questionnaire study found that the current basic knowledge about pain amongst young anaesthesiologists is deficient. The physician's major concerns were opioid addiction and respiratory depression with opioid usage. The results of pre and post-test questionnaire survey have shown that pain education can help in improving knowledge of pain management.

Measuring safety culture in Dutch primary care: psychometric characteristics of the SCOPE-PC questionnaire  

PubMed Central

Background Patient safety has been a priority in primary healthcare in the last years. The prevailing culture is seen as an important condition for patient safety in practice and several tools to measure patient safety culture have therefore been developed. Although Dutch primary care consists of different professions, such as general practice, dental care, dietetics, physiotherapy and midwifery, a safety culture questionnaire was only available for general practices. The purpose of this study was to modify and validate this existing questionnaire to a generic questionnaire for all professions in Dutch primary care. Methods A validated Dutch questionnaire for general practices was modified to make it usable for all Dutch primary care professions. Subsequently, this questionnaire was administered to a random sample of 2400 practices from eleven primary care professions. The instrument’s factor structure, reliability and validity were examined using confirmatory and explorative factor analyses. Results 921 questionnaires were returned. Of these, 615 were eligible for factor analysis. The resulting SCOPE-PC questionnaire consisted of seven dimensions: ‘open communication and learning from errors’, ‘handover and teamwork’, ‘adequate procedures and working conditions’, ‘patient safety management’, ‘support and fellowship’, ‘intention to report events’ and ‘organisational learning’ with a total of 41 items. All dimensions had good reliability with Cronbach’s alphas ranging from 0.70 – 0.90, and the questionnaire had a good construct validity. Conclusions The SCOPE-PC questionnaire has sound psychometric characteristics for use by the different professions in Dutch primary care to gain insight in their safety culture.

Validation of a French Version of the Quality of Life "Celiac Disease Questionnaire"  

PubMed Central

Background and Objective Celiac disease (CD) is a common chronic autoimmune disorder. Both the manifestations of the disease and the burden of the compulsory life-long gluten-free diet (GFD) have been shown to be associated with impairment of health-related quality of life. The objectives of this study were to provide a cross-cultural adaptation of the specific quality of life “Celiac Disease Questionnaire” (CDQ) and to analyze its psychometric properties. Materials and Methods A cross-cultural French adaptation of the CDQ (F-CDQ) was obtained according to the revised international guidelines. The questionnaire was administered at baseline to 211 patients with biopsy proven CD followed-up in a single tertiary referral centre. The questionnaire was also administered after 7 days and 6 months. Reliability (intraclass correlation coefficients (ICC), Cronbach's alpha and Bland and Altman graphical analysis), validity (factorial structure and Rasch analysis, convergent validity), and responsiveness (effect size) of the F-CDQ were studied. Results The reliability of the F-CDQ was excellent with ICC and Cronbach's alpha coefficients being between 0.79 and 0.94 for the four subscales and the total score. The factorial structure and the Rasch analysis showed that the four dimensions of the original instrument were retained. Correlations with external measures (a generic measure of quality of life, an anxiety and depression instrument, a self-assessed disease severity, and clinical manifestations) were all in the expected direction confirming the validity of the instrument. Responsiveness was studied and effect sizes ?0.20 were demonstrated for most of the subscales for patients who reported improvement or deterioration after 6 months. Conclusion The F-CDQ retains the psychometric properties of the original instrument and should be useful in cross-national surveys and to assess outcome in clinical trials involving patients with CD.

Sources of nonresponse to the Federal Waterfowl Hunter Questionnaire Survey  

USGS Publications Warehouse

Response rates to the Federal Waterfowl Hunter Questionnaire Survey (WHQS) have declined since the 1950's, suggesting that harvest estimates may be biased. Consequently, we investigated reasons for WHQS nonresponse using surveys of waterfowl hunters in Arkansas, California, Louisiana, Minnesota, New Jersey, and Texas [USA]. Sampling frames were constructed using lists of buyers of state hunting licenses or state duck stamps. We mailed questionnaires to 16,452 randomly selected hunters, with 2 follow-up mailings at 3-week intervals. Questionnaires were completed by 8,812 respondents, and a further 587 interviews were conducted by telephone. Post offices accounted for between 53.7% (Minn.) and 92.8% (N.J.) of federal waterfowl duck stamp sales, and stores accounted for most other sales. Of hunters who bought a federal waterfowl stamp from sample post offices, between 16.7% (Minn.) and 40.0% (Ark.) reported receiving a WHQS contact card. Of those receiving contact cards, between 30.0% (N.J.) and 64.3% (La. and Tex.) reported returning them. Because survey coverage of the target population is poor, we recommend that a new sampling frame be developed for the WHQS.

Reducing Missed Laboratory Results: Defining Temporal Responsibility, Generating User Interfaces for Test Process Tracking, and Retrospective Analyses to Identify Problems  

PubMed Central

Researchers have conducted numerous case studies reporting the details on how laboratory test results of patients were missed by the ordering medical providers. Given the importance of timely test results in an outpatient setting, there is limited discussion of electronic versions of test result management tools to help clinicians and medical staff with this complex process. This paper presents three ideas to reduce missed results with a system that facilitates tracking laboratory tests from order to completion as well as during follow-up: (1) define a workflow management model that clarifies responsible agents and associated time frame, (2) generate a user interface for tracking that could eventually be integrated into current electronic health record (EHR) systems, (3) help identify common problems in past orders through retrospective analyses.

The two-track model of bereavement questionnaire (TTBQ): development and validation of a relational measure.  

PubMed

The Two-Track Model of Bereavement Questionnaire (TTBQ) was designed to assess response to loss over time. Respondents were 354 persons who completed the 70-item self-report questionnaire constructed in accordance with the Two-Track Model of Bereavement. Track I focuses on the bereaved's biopsychosocial functioning and Track II concerns the bereaved's ongoing relationship to the range of memories, images, thoughts, and feeling states associated with the deceased. Factor analysis identified 5 factors that accounted for 51% of the variance explained. In accord with the theoretical and clinical model, 3 factors were primarily associated with the relationship to the deceased (Track II): Active Relational Grieving, Close and Positive Relationship, and Conflictual Relationship; and 2 factors with aspects of functioning (Track I): General Biopsychosocial Functioning and Traumatic Perception of the Loss. Construct and concurrent validity were examined and were found satisfactory. Differences by kinship, cause of death, gender, and time elapsed were examined across the 5 factors, the total TTBQ, and the ITG. The new measure is shown to have both construct and concurrent validity. Discussions of the results and implications for the measurement of response to loss conclude the article. PMID:19368062

Evaluation and revision of questionnaires for use among low-literacy immigrant Latinos  

PubMed Central

As more Spanish speaking immigrants participate in and become the focus of research studies, questions arise about the appropriateness of existing research tools. Questionnaires have often been adapted from English language instruments and tested among college- educated Hispanic-Americans. Little has been written regarding the testing and evaluation of research tools among less educated Latino immigrants. The purpose of this study was to revise and evaluate the appropriateness of a battery of existing Spanish-language questionnaires for a physical activity intervention for immigrant Hispanic women. A three-step process was utilized to evaluate, adapt and test Spanish versions of the Self-Efficacy and Exercise Habits Survey, an abbreviated version of the Hispanic Stress Inventory-Immigrant version and the Latina Values Scale. The revised tools demonstrated acceptable validity and reliability. The adaptations improved the readability of the tools, resulting in a greater response rate, less missing data and fewer extreme responses. Psychometric limitations to the adaptation of Likert scales are discussed.

Validation of a self-administered questionnaire for assessing occupational and environmental exposures of pregnant women  

SciTech Connect

The present investigation sought to determine whether a self-administered questionnaire could be used to obtain occupational information from pregnant women attending the obstetrical clinics at the University of California, San Francisco from July to November 1986. The authors compared the accuracy of responses of 57 women on the self-administered questionnaire with those obtained on a detailed clinical interview by an occupational health professional. The self-administered questionnaire and the clinical interview included information on the woman's job title, the type of company she worked for, the level of physical activity, her exposures on the job and at home, and her partner's occupation. The authors also examined whether the validity of the self-administered questionnaire could be improved on review by an industrial hygienist. The questionnaire took less than 20 minutes to complete, with over 90% of the women answering three-quarters of it. It was substantially accurate in obtaining information on number of hours worked during pregnancy, type of shift worked, and stress level in the workplace; exposure to radiation, video display terminals, fumes, gases, and cigarette smoke in the workplace; and exposure to pesticides, paint, and cigarette smoke at home. On those variables for which the responses on the self-administered questionnaire were less accurate, review by the industrial hygienist improved the level of accuracy considerably. These findings suggest that a self-administered questionnaire can be used to obtain valid information from pregnant women attending a prenatal clinic.

Wild edible plants of Belarus: from Rostafi?ski's questionnaire of 1883 to the present  

PubMed Central

Background Belarus is an Eastern European country, which has been little studied ethnobotanically. The aim of the study was to compare largely unpublished 19th century sources with more contemporary data on the use of wild food plants. Methods The information on 19th century uses is based on twelve, mainly unpublished, responses to Józef Rostafi?ski’s questionnaire from 1883, and the newly discovered materials of the ethnographer Micha? Federowski, who structured his data according to Rostafi?ski’s questionnaire and documented it with voucher specimens. Rostafi?ski’s questionnaire was concerned mainly with Polish territories, but for historical reasons this also encompassed a large part of Belarus, and we analyzed only the twelve responses (out of the few hundred Rostafi?ski obtained), which concerned the present Belarus. These data were compared with a few 20th century ethnographic sources, and our own 40 interviews and questionnaires from Belarus. Results and discussion 58 taxa of wild food plants used in the 19th century were identified. Some of them are still used in modern Belarus, others are probably completely forgotten. In the 19th century several species of wild greens were widely used for making soups. Apart from Rumex, other wild greens are now either forgotten or rarely used. The list of species used in the 20th and 21st century encompasses 67 taxa. Nearly half of them were mentioned by Rostafi?ski’s respondents. The list of fruit species has not changed much, although in the 19th century fruits were mainly eaten raw, or with dairy or floury dishes, and now apart from being eaten raw, they are incorporated in sweet dishes like jams or cakes. Modern comparative data also contain several alien species, some of which have escaped from cultivation and are gathered from a semi-wild state, as well as children's snacks, which were probably collected in the 19th century but were not recorded back then. Conclusion The responses to Rostafi?ski from 1883 present extremely valuable historical material as the use of wild food plants in Belarus has since undergone drastic changes, similar to those, which have taken place in other Eastern European countries.

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

PubMed

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.

Munc18-1 haploinsufficiency results in enhanced anxiety-like behavior as determined by heart rate responses in mice.  

PubMed

Heterozygous (HZ) missense mutations in the gene encoding syntaxin binding protein 1 (Stxbp1 or Munc18-1), a presynaptic protein essential for neurotransmitter release, causes early infantile epileptic encephalopathy, abnormal brain structure and mental retardation in humans. Here we investigated whether the mouse model mimics symptoms of the human phenotype. The effects of the deletion of munc18-1 were studied in HZ and wild-type (WT) mice based on heart rate (HR) and its variability (HRV) as independent measures to expand previous behavioral results of enhanced anxiety and impaired emotional learning suggesting mild cognitive impairments. HR responses were assessed during novelty exposure, during the expression and extinction of conditioned tone-dependent fear and during the diurnal phase. Novelty exposure yielded no differences in activity patterns between the two genotypes, while maximum HR differed significantly (WT: 770 bpm; HZ: 790 bpm). Retention tests after both auditory delay and trace fear conditioning showed a delayed extinction of the conditioned HR response in HZ mice compared to WT mice. Since the HR versus HRV correlation and HR dynamics assessed by nonlinear methods revealed similar function in HZ and WT mice, the higher HR responses of munc18-1 HZ mice to different emotional challenges cannot be attributed to differences in autonomic nervous system function. Thus, in contrast to the adverse consequences of deletion of a single allele of munc18-1 in humans, C57BL/6J mice show enhanced anxiety responses based on HR adjustments that extend previous results on the behavioral level without support of cognitive impairment, epileptic seizures and autonomic dysregulation.

Cross-cultural adaptation and validation of the VISA-A questionnaire for German-speaking Achilles tendinopathy patients  

PubMed Central

Background Achilles tendinopathy is the predominant overuse injury in runners. To further investigate this overload injury in transverse and longitudinal studies a valid, responsive and reliable outcome measure is demanded. Most questionnaires have been developed for English-speaking populations. This is also true for the VISA-A score, so far representing the only valid, reliable, and disease specific questionnaire for Achilles tendinopathy. To internationally compare research results, to perform multinational studies or to exclude bias originating from subpopulations speaking different languages within one country an equivalent instrument is demanded in different languages. The aim of this study was therefore to cross-cultural adapt and validate the VISA-A questionnaire for German-speaking Achilles tendinopathy patients. Methods According to the "guidelines for the process of cross-cultural adaptation of self-report measures" the VISA-A score was cross-culturally adapted into German (VISA-A-G) using six steps: Translation, synthesis, back translation, expert committee review, pretesting (n = 77), and appraisal of the adaptation process by an advisory committee determining the adequacy of the cross-cultural adaptation. The resulting VISA-A-G was then subjected to an analysis of reliability, validity, and internal consistency in 30 Achilles tendinopathy patients and 79 asymptomatic people. Concurrent validity was tested against a generic tendon grading system (Percy and Conochie) and against a classification system for the effect of pain on athletic performance (Curwin and Stanish). Results The "advisory committee" determined the VISA-A-G questionnaire as been translated "acceptable". The VISA-A-G questionnaire showed moderate to excellent test-retest reliability (ICC = 0.60 to 0.97). Concurrent validity showed good coherence when correlated with the grading system of Curwin and Stanish (rho = -0.95) and for the Percy and Conochie grade of severity (rho 0.95). Internal consistency (Cronbach's alpha) for the total VISA-A-G scores of the patients was calculated to be 0.737. Conclusion The VISA-A questionnaire was successfully cross-cultural adapted and validated for use in German speaking populations. The psychometric properties of the VISA-A-G questionnaire are similar to those of the original English version. It therefore can be recommended as a sufficiently robust tool for future measuring clinical severity of Achilles tendinopathy in German speaking patients.

The National Eye Institute Visual Function Questionnaire 25 (NEI-VFQ-25) is the most commonly used patient-reported outcome measure to assess vision-related quality of life in patients with glaucoma. Glaucoma negatively affects the composite and several NEI-VFQ subscale scores; this effect is correlated with the severity of glaucomatous visual field loss. Contrast sensitivity, glare, and dark adaptation are potential items that could be added to the NEI-VFQ to make it more responsive to changes in vision-related quality of life in patients with glaucoma.

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.

Psychometric Properties of Questionnaires on Functional Health Status in Oropharyngeal Dysphagia: A Systematic Literature Review  

PubMed Central

Introduction. Questionnaires on Functional Health Status (FHS) are part of the assessment of oropharyngeal dysphagia. Objective. To conduct a systematic review of the literature on the psychometric properties of English-language FHS questionnaires in adults with oropharyngeal dysphagia. Methods. A systematic search was performed using the electronic databases Pubmed and Embase. The psychometric properties of the questionnaires were determined based on the COSMIN taxonomy of measurement properties and definitions for health-related patient-reported outcomes and the COSMIN checklist using preset psychometric criteria. Results. Three questionnaires were included: the Eating Assessment Tool (EAT-10), the Swallowing Outcome after Laryngectomy (SOAL), and the Self-report Symptom Inventory. The Sydney Swallow Questionnaire (SSQ) proved to be identical to the Modified Self-report Symptom Inventory. All FHS questionnaires obtained poor overall methodological quality scores for most measurement properties. Conclusions. The retrieved FHS questionnaires need psychometric reevaluation; if the overall methodological quality shows satisfactory improvement on most measurement properties, the use of the questionnaires in daily clinic and research can be justified. However, in case of insufficient validity and/or reliability scores, new FHS questionnaires need to be developed using and reporting on preestablished psychometric criteria as recommended in literature.

Measurement Properties of Questionnaires Assessing Complementary and Alternative Medicine Use in Pediatrics: A Systematic Review  

PubMed Central

Objective Complementary and alternative medicine (CAM) is commonly used by children, but estimates of that use vary widely partly due to the range of questionnaires used to assess CAM use. However, no studies have attempted to appraise measurement properties of these questionnaires. The aim of this systematic review was to critically appraise and summarize measurement properties of questionnaires of CAM use in pediatrics. Study design A search strategy was implemented in major electronic databases in March 2011 and conference websites, scientific journals and experts were consulted. Studies were included if they mentioned a questionnaire assessing the prevalence of CAM use in pediatrics. Members of the team independently rated the methodological quality of the studies (using the COSMIN checklist) and measurement properties of the questionnaires (using the Terwee and Cohen criteria). Results A total of 96 CAM questionnaires were found in 104 publications. The COSMIN checklist showed that no studies reported adequate methodological quality. The Terwee criteria showed that all included CAM questionnaires had indeterminate measurement properties. According to the Cohen score, none were considered to be a well-established assessment, two approached the level of a well-established assessment, seven were promising assessments and the remainder (n?=?87) did not reach the score’s minimum standards. Conclusion None of the identified CAM questionnaires have been thoroughly validated. This systematic review highlights the need for proper validation of CAM questionnaires in pediatrics, which may in turn lead to improved research and knowledge translation about CAM in clinical practice.

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
