Full textAbstract:
High precision data from household travel survey (HTS) is extremely important for the transportation research, traffic models and policy formulation. Traditional methods of data collection were imprecise because they relied on people’s memories of trip information, such as date and location, and the remainder data had to be obtained by certain supplemental tools. The traditional methods suffered from intensive labor, large time consumption, and unsatisfactory data precision. Recent research trends to employ smartphone apps to collect HTS data. In this study, there are two goals to be addressed. First, a smartphone app is developed to realize a smartphone-based method only for data collection. Second, the researcher evaluates whether this method can supply or replace the traditional tools of HTS. Based on this premise, the smartphone app, TravelSurvey, is specially developed and used for this study. TravelSurvey is currently compatible with iPhone 4 or higher and iPhone Operating System (iOS) 6 or higher, except iPhone 6 or iPhone 6 plus and iOS 8. To evaluate the feasibility, eight individuals are recruited to participate in a pilot HTS. Afterwards, seven of them are involved in a semi-structured interview. The interview is designed to collect interviewees’ feedback directly, so the interview mainly concerns the users’ experience of TravelSurvey. Generally, the feedback is positive. In this study, the pilot HTS data is successfully uploaded to the server by the participants, and the interviewees prefer this smartphone-based method. Therefore, as a new tool, the smartphone-based method feasibly supports a typical HTS for data collection.

Full textAbstract:
Meeting patient expectations in relation to pain management is an essential component of palliative and end-of-life care. However, previous research has demonstrated that pain is highly prevalent, especially during the four months prior to death. Poorly controlled pain contributes to cognitive failure, depression and an inability to complete daily activities. Unfortunately, pain and symptom management are often inadequate for patients placed in hospice care. The purpose of this study is to evaluate the perspectives of hospice nurses on complementary and alternative therapies to determine if there is an educational need in order to aide in the management of chronic pain in older adults. A survey was developed in order to determine the nursing perceptions of complementary and alternative therapies. A total of 24 participants were recruited. The survey targeted 28 complementary and alternative therapies most commonly used as defined by National Institute for Complementary and Alternative Medicines (NCCAM). Each therapy was ranked on several aspects including perceptions, personal experience, and present knowledge and training. After completing the survey it was found that all participants were either eager or open to use some complementary and alternative therapies in their workplace, in spite of having an educational barrier on how to implement them, and wanted these therapies to become available to patients, families, and staff.<br>B.S.N.<br>Bachelors<br>Nursing<br>Nursing

Dispersed low-frequency radio astronomical pulses may result from exploding primordial
black holes, gamma ray bursts, supernovae, or mergers of exotic objects, but have not yet
been detected. Detection would be of great scientific significance because such events must
involve extreme physics. The transient nature of these events makes detection unlikely with
traditional instruments due to lack of sensitivity to single pulses and narrow field of view.
For this thesis, a low-frequency wide-bandwidth astronomical search instrument has been
developed as an alternative approach. This instrument consists of a single dipole which
yields all-sky field of view, albeit at reduced sensitivity. The spectrum from 37 - 55 MHz
is coherently digitized at 200 million samples per second, recorded, and analyzed off-line for
the presence of dispersed pulses. A preliminary survey has been made at a remote site in
western North Carolina. In a 20 minute observation, 9 detections greater than 6.5 occurred, corresponding to pulses of 20 ms duration and dispersion measures (DMs) ranging from 15 to 70 pc cm−3 . In addition, groups of pulses were detected ( 5) at DMs of 43.1, 52.1,
and 52.2 pc cm−3 . The possibility of association with known pulsars is considered; however,
it is also possible these are due simply to radio frequency interference. Improvements to this
instrument and survey technique are suggested.<br>Master of Science

Full textAbstract:
Very Long Baseline Interferometry (VLBI) has significant advantages in disentangling active galactic nuclei (AGN) from star formation, particularly at intermediate to high-redshift due to its high angular resolution and insensitivity to dust. Surveys using VLBI arrays are only just becoming practical over wide areas with numerous developments and innovations (such as multi-phase centre techniques) in observation and data analysis techniques. However, fully automated pipelines for VLBI data analysis are based on old software packages and are unable to incorporate new calibration and imaging algorithms. In this work, the researcher developed a pipeline for VLBI data analysis which integrates a recent wide-field imaging algorithm, RFI excision, and a purpose-built source finding algorithm specifically developed for the 64kx64k wide-field VLBI images. The researcher used this novel pipeline to process 6% (~ 9 arcmin2 of the total 160 arcmin2) of the data from the CANDELS GOODS- North extragalactic field at 1.6 GHz. The milli-arcsec scale images have an average rms of a ~ 10 uJy/beam. Forty four (44) candidate sources were detected, most of which are at sub-mJy flux densities, having brightness temperatures and luminosities of >5x105 K and >6x1021 W Hz-1 respectively. This work demonstrates that automated post-processing pipelines for wide-field, uniform sensitivity VLBI surveys are feasible and indeed made more efficient with new software, wide-field imaging algorithms and more purpose-built source- finders. This broadens the discovery space for future wide-field surveys with upcoming arrays such as the African VLBI Network (AVN), MeerKAT and the Square Kilometre Array (SKA).

Full textAbstract:
Introduction: Thromboprophylaxis recommendations for hospitalized cancer are based on trials done for the general medically patients, as there are no randomized clinical trials(RCTs) looking at thromboprophylaxis in medically ill patients with cancer. Methods: To determine if thromboprophylaxis is safe and effective to prevent VTE these patients, a Systematic Review(SR) was done. A survey was performed to assess: clinical equipoise, trial design and minimally clinically important difference(MCID) for a potential trial. Lastly, a pilot study for an RCT was designed. Results: The pooled RR of VTE was 0.91 (95%CI:0.21 to 4.0;I2:68%) among hospitalized cancer patients receiving thromboprophylaxis compared to placebo. 63.9% believe there is clinical equipoise and 58.3% would consider participating in a RCT comparing different agents/dosing. The MCID for absolute reduction in symptomatic VTE between two arms was 2% and for “acceptable” increase in major bleeding events was 1%. Conclusion: The risk-benefit ratio of current doses of thromboprophylaxis administered to hospitalized cancer patients is unclear and additional RCTs are necessary.

Full textAbstract:
The study objective was to develop and evaluate the psychometric properties of preference-based measures in osteoporosis. Preference scenarios were constructed for marker health states associated with osteoporosis using the feeling thermometer. The reliability, validity and sensitivity to change of these measures and the standard gamble were evaluated in 42 women from four different patient subgroups. The four subgroups of women included women commencing hormone replacement, and women with recent wrist, vertebral or hip fractures. The reason for looking at different groups of women was to establish the feasibility of eliciting preferences in women with varying degrees of osteoporosis. Also, for cost-effectiveness analyses in osteoporosis, estimates of quality of life are required for the four different subgroups. The validity and sensitivity to change of the feeling thermometer and standard gamble were compared with the Health Utilities Index (HUI) and SF-36. All subgroups were reassessed 2-3 months following their first interview. (Abstract shortened by UMI.)

Full textAbstract:
Background:Smoking is a risk factor for periodontitis, and tobacco use among adults has remained unaltered at 25 % between 2007 to 2016. Dental personnel are important informers about health risks of smoking including the association between smoking and periodontitis. Aims and methods:A survey was conducted where three schools in Umeå, Sweden participated. 128 students were divided into a control and a test group. An intervention including a lecture about healthy oral conditions was given to the control group and a lecture about smoking and its association to periodontitis to the test group. Questionnaires about the students smoking habits and their knowledge about adverse effects of smoking were filled in by the students before and after the intervention. The aim of the study was to investigate if short information given by dental personnel could change the attitude to smoking and the knowledge about its correlation to periodontitis among adolescents. Results:According to our study, 28/128 students (22 %) smoked at baseline. At follow up, the students in the test group demonstrated increased knowledge about the effects of smoking on periodontal health compared to the control group. Motivating factors to quit smoking were the aesthetical side effects of smoking and its association to periodontitis. Conclusion:The study suggested that short information in school can alter the attitude toward smoking and may serve as a useful tool to prevent smoking in adolescents. Knowledge about adverse aesthetical and periodontal effects of smoking may be useful in smoking prevention.

The prevention researcher must therefore turn his attention to the risk and protective factors associated with the incidence of these problems, which must be targeted by preventive interventions planning and implementation. The aim of this study is to describe the main risk and protective factors associated with the emergence of violent behaviors, with engaging in delinquent acts and with drug use among youth and adolescents. Risk factors and protective are presented at community, school, family, peer and individual levels. It is necessary to intervene by maximizing protective factors and reducing risk factors, aiming at preventing or delaying the occurrence of the unwanted behaviors. It is important to be aware of the degree of exposure to precursors of theses behaviors when guiding prevention efforts in the community.

Jansky Very Large Array (VLA) primary beam (FWHM circle minus(1/2) approximate to 4.'25) in the GOODS-N field contains 32 sources with S-p greater than or similar to 2 mu Jy beam(-1) and optical and/or near-infrared (OIR) counterparts. Most are about as large as the star-forming regions that power them. Their median FWHM major axis is <theta(M)>= 167 +/- 32 mas approximate to 1.2 +/- 0.28 kpc, with rms scatter approximate to 91 mas approximate to 0.79 kpc. In units of the effective radius re that encloses half their flux, these radio sizes are re approximate to 69 +/- 13 mas approximate to 509 +/- 114 pc, with rms scatter approximate to 38 mas approximate to 324 pc. These sizes are smaller than those measured at lower radio frequencies, but agree with dust emission sizes measured at mm/sub-mm wavelengths and extinction-corrected H alpha sizes. We made a lowresolution (theta(1/2) = 1."0) image with approximate to 10x better brightness sensitivity, in order to detect extended sources and measure matched-resolution spectral indices alpha(10 GHz)(1.4 GHz) 10 GHz. It contains six new sources with Sp. 3.9 mJy beam-1 and OIR counterparts. The median redshift of all 38 sources is similar to z similar to = 1.24 +/- 0.15. The 19 sources with 1.4 GHz counterparts have a median spectral index of <alpha(1.4 GHz) (10 GHz)> = -0.74 +/- 0.10 10 GHz, with rms scatter approximate to 0.35. Including upper limits on a for sources not detected at 1.4 GHz flattens the median to <alpha(1.4 GHz) (10 GHz)> greater than or similar to -0.61 10 GHz, suggesting that the mu Jy radio sources at higher redshifts-and hence those selected at higher rest-frame frequencies-may have flatter spectra. If the non-thermal spectral index is alpha(NT) approximate to -0.85, the median thermal fraction of sources selected at median rest-frame frequency approximate to 20 GHz is greater than or similar to 48%.

Full textAbstract:
Background: Today, the majority of medical graduates in South Africa and internationally, are female. Current literature suggests that the surgical workforce does not reflect this gender integration. This trend, as well as a decrease in the popularity of general surgery as career choice, has been investigated internationally. It is postulated that gender plays a significant role in specialty choice. In the midst of the gender debate, there are also generational shifts in preferences around work and lifestyle that need to be considered. Paucity of data about these trends from the African continent exists. Aim: The aim of this study was to determine the gender, generational and discipline-specific factors that are currently impacting on general surgery as a career and specialty choice by administering questionnaires to undergraduate students, surgical trainees and consultant surgeons. The questionnaires were designed to determine the: 1. "Status" of female general surgeons as opposed to male general surgeons. 2. "Perceptions" about female general surgeons opposed to male general surgeons. 3. "Challenges" faced by general surgeons, both male and female. Methods: An institutionally validated, self-administered questionnaire was used to gather data on the current status, perceptions and challenges pertaining to general surgeons, male and female, at the University of Cape Town. The questionnaires were distributed to a group of final-year medical students, and to current surgical registrars and surgical consultants in the department of surgery, and were analysed with a particular focus on gender. Results: The response rate from the surgical department was 67.8%: 29 (51%) respondents were consultant surgeons (six female and 23 male), and 28 were surgical registrars (11 female and 17 male). Of the 114 students invited, 59 (51.7%) completed the survey: 18 male and 41 female. Status: The small numbers made it difficult to comment on the status of female surgeons within the discipline. However, the average age of female surgical consultants were six years younger than male consultants (39 vs. 45). Two female consultants were the head of a firm, none has been on the editorial board of a peer-reviewed journal, nor has acted as postgraduate research supervisors, but their average number of publications is almost equivalent to those of the male consultants. Perceptions: A statistically significant proportion of registrars (p = 0.03; six [35%] female and 16 [40%] male) felt that women had an advantage when applying for a surgical training post. A total of 19 (33%) felt that there are too many female surgical registrars; only two (3.5%) felt there are too few. Nine (32%) registrars felt that more female surgeons complicate the departmental routine - male participants were statically more likely to consider a female presence disruptive (p = 0.02). Fourteen (50%) registrars, 13 (45%) consultants and 36 (61%) students think men are better suited for a career in general surgery, but the majority across all groups considers female surgeons just as technically competent as male surgeons. A minority of registrars (5/28: 18%) and consultants (4/29: 13.7%) perceive female surgeons to portray a lot of masculine qualities, while 24 (40.6%) students think female surgeons are more assertive, aggressive and decisive than women in other specialties. Challenges: Poor work-life balance, the effect their surgical career has on their family and personal relationships, together with meeting research and academic demands, were identified as major challenges across both genders in the consultant and registrar groups. The majority of students, both male - 13 (72%), and female - 28 (68%), indicated that perceived lifestyle during training will deter them from choosing a career in general surgery. Nineteen (46.3%) female and six (33%) male students are deterred by the influence a surgical career may have on their personal relationships. Conclusion: This pilot study moves the gender conversation in surgery beyond balancing numbers. More women in surgery does not necessarily translate into better integration - in our survey, men are still considered better suited for a career in general surgery. Women are considered disruptive to the discipline and are perceived to face more challenges in carving out a successful career in general V surgery. There are, however, challenges that increasingly affect both genders. As the number of women in the surgical workforce rise, it will be imperative to distinguish what challenges are discipline rather than gender-related. Addressing gender as well as generational challenges may enable the discipline to draw the best candidates and restore general surgery to its position as a popular career choice.

Full textAbstract:
Thesis: M.C.P., Massachusetts Institute of Technology, Department of Urban Studies and Planning, 2018.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references (pages 128-130).<br>As water crises continue to occur globally, it would be invaluable to have easy-to-access, comparable and localized data on public water management worldwide; unfortunately such information is not available from a single public source (Koelbel et al. 2018). Information on water risk that does exist does not cover public water management at a granularity that would be useful to industrial facilities and local utilities. Even at a national or state-level, datasets on water risk are woefully incomplete. Given these gaps, the World Resources Institute (WRI) and the Massachusetts Institute of Technology Sloan Sustainability Initiative (MIT-SSI) are seeking to crowdsource multinational companies' information on public water management and water risk to see whether a reliable, globally comparable, and centralized geodatabase can be developed by pooling information that private actors use to map and identify local water risk and public water management efforts essential to their decision-making. WRI and MIT-SSI began an initial pilot study in 2017 with a survey of six multinational companies and 41 of their industrial processing and manufacturing facilities in 14 countries. These corporations were selected because they operate facilities globally, pursue extensive internal environmental sustainability work, and regularly collect data on water use and discharge at the site level. The initial pilot survey instrument covered (i) the availability of quantified, public information on water availability, demand, and quality; (2) the state of the relevant infrastructure including reliability of water supply and availability of wastewater treatment services; (3) existing water access regulations and consistency of regulatory enforcement; and (4) crisis response. I was asked to analyze these survey responses along with the results of follow-up interviews conducted in coordination with site visits to a selection of the survey respondents from California and India. I set out to determine whether the risk indicators used by the WRI/MIT-SSI partnership accurately portray on-the-ground public water management circumstances at the facility level for companies operating in both low and high-risk areas. I also tried to determine whether the water risk indicators developed by WRI/MIT-SSI are comparable, credible, and relevant across a range of manufacturing and industrial processing sites. In order to assess the validity of the initial survey instrument and the data it generated, I completed 27 interviews of 32 academics, public water managers, corporate facility managers, and individuals associated with non-profit organizations engaged in water and sanitation. I also visited two facilities in Southern California and Maharashtra, India while following up with six facility and environmental managers who completed the initial surveys in these regions. I found the pilot study responses generally reflected local public water risk management conditions and were trusted and found credible by all stakeholder groups interviewed. Furthermore, officials and stakeholders engaged in public water management, advocacy, and oversight thought the data generated by the survey instrument would be useful in a variety of ways as long as enough data points are provided and anonymity of corporate respondents is maintained. Unless responses can remain anonymous, there were fears that particular sites might be subject to litigation or regulatory retaliation. Facility managers said that they were able to answer all the survey questions based on what they already knew from their facilities' daily operations and from information regularly collected for internal environmental reporting and efficiency efforts. In my view, the responses appeared reasonably accurate and they were generated in a timely manner. Furthermore, collecting this information from corporate actors is not only feasible but is preferred in some contexts. My recommendations for improving the survey instrument emphasize the need to expand the scope of the survey while remaining cognizant of the need to keep the instrument brief. This includes collecting data on the availability of recycled and reclaimed water and addressing the existence of regulations that require the use and treatment of wastewater on-site. Furthermore, concerns about whether the survey respondent is qualified to answer the questions regularly arose; therefore, an additional recommendation is to provide a question to validate whether the respondent works onsite or has operating knowledge of water management in the region. WRI and the Pacific Institute, who will be superseding MIT-SSI in the project as it moves forward, should collaborate with additional institutional and corporate partners to ensure that more data points are collected globally as this will enhance the global credibility of survey findings.<br>by Cristina Alene Logg.<br>M.C.P.

Full textAbstract:
Background: Patients undergoing colorectal cancer resections are at risk for delayed recovery. A previous prehabilitation program using exercise alone has shown limited impact in enhancing functional capacity and recovery. We compared the impact of a new trimodal prehabilitation program which includes exercise, nutritional and psychological therapy to patients undergoing standard care. Literature Review: Limited literature exists in enhancing functional capacity in abdominal surgery. Studies have focused on exercise alone and have reported negative results. Protein supplementation combined with exercise may stimulate muscle gain and anxiety reduction may improve compliance and recovery. Methods: In this pre/post intervention study, functional walking capacity during prehabilitation and at 8 weeks after surgery was compared between 42 patients having completed the trimodal prehabilitation intervention and 45 previously assessed controls. Results: Functional walking capacity improved by an average 42 ± 41 meters during prehabilitation. At 8 weeks after surgery, patients undergoing prehabilitation were 64 meters above controls on multivariate analysis. 81% of prehabilitated patients were considered recovered versus 40% of controls. There was no difference in postoperative complication rates.Conclusion: A trimodal prehabilitation program improved both functional capacity preoperatively and postoperative functional recovery.<br>Contexte: Les patients subissant une résection pour cancer colorectal sont à risque d'un rétablissement retardé. Un programme de préhabilitation d'exercice physique seul a démontré un impact limité. Nous avons comparé l'impact d'un nouveau programme de préhabilitation trimodale qui inclut l'exercice, la nutrition, et la psychologie aux patients recevant des soins standard. Revue de la littérature: Peu d'études existent sur l'amélioration de la capacité functionelle en chirurgie abdominale. Ces études ont mis l'accent sur l'exercice seul et ont eu des résultats négatifs. La supplémentation en protéines combiné avec l'exercice peut stimuler le gain de muscle, et la réduction de l'anxiété peut améliorer la participation et le rétablissement. Méthodes: Dans cette étude pré/post intervention, la capacité fonctionelle de marche durant la période de préhabilitation et à 8 semaines après la chirurgie ont été comparé entre 42 patients ayant terminé la préhabilitation trimodale et 45 contrôles évalués antérieurement. Résultats: La capacité fonctionnelle de marche s'est ameliorée de 42 ± 41 mètres lors de la préhabilitation. À 8 semaines, les patients ayant terminé la préhabilitation étaient 64 mètres au-dessus des contrôles sur analyse multivariée. 81% des patients en préhabilitation s'étaient rétablis versus 40% des contrôles. Il n'y avait aucune différence dans les taux de complications postopératoires.Conclusion: Un programme de préhabilitation trimodale a amélioré à la fois la capacité fonctionelle en préoperatoire et le rétablissement postopératoire.

Background. Peripheral vein infusion thrombophlebitis (PVIT) is a complication of intravenous therapy. We hypothesized that inherited thrombophilia may increase the risk of PVIT.<br>Purpose. In preparation for a multi-center study of our hypothesis, we conducted a pilot study to estimate PVIT incidence, measure the prevalence of inherited thrombophilia, and pilot test the study procedures.<br>Methods. A prospective case-control study of 25 cases (patients with PVIT) matched on catheter duration to 25 controls. PVIT risk factors and inherited thrombophilia were assessed.<br>Results. PVIT incidence was 14 per 1000 catheter-days. There were no significant differences in the prevalence of the inherited thrombophilia disorders among cases and controls (32% vs. 48%). A previous history of PVIT was noted in 4 cases compared to 0 controls. Procedural problems included a high rate of non-consent and inadequate communication with the laboratory.<br>Conclusions. Though an association between PVIT and inherited thrombophilia was not shown, a previous history of PVIT among cases supports a biological predisposition to PVIT. Our pilot study did provide useful data on PVIT incidence and procedural issues used to design a more definitive study of inherited thrombophilia and PVIT.

ABSTRACTPreoperative Activity Level and Outcomes in Older <&hyphen>¨Adult Cardiac Surgery Patients: A Pilot StudyDon Howard Sorensen Jr.College of Nursing, BYUMaster of SciencePurpose: To assess the relationship between preoperative physical activity levels and health related quality of life on intra- and post-hospital outcomes following scheduled cardiothoracic surgery in older adults.Rationale/Background: Adults age 50 and older tend to accumulate more sedentary time and are less physically active. Sedentary behavior is linked with early morbidity and death and may predispose patients to postoperative complications. Preoperative activity levels and its relationship to surgical outcomes is an underexplored area. Insight on this topic could influence how to optimize interventions prior to surgery to improve outcomes. Methods: Seven participants were fitted with an ActiGraph GT3X+ accelerometer to measure preoperative activity levels for 1 week and complete the RAND Short Form-36 health-related quality of life tool. This process was then supposed to be repeated during the first and last weeks of cardiac rehabilitation (rehab). This information, along with demographics, was then correlated with information pulled from the Society of Thoracic Surgeons database on post-surgical outcomes and the 6-minute walk tests (6MWT) done during rehab. Results: The only statistically significant result was participants who experienced some type of intra-hospital complication also scored low in emotional wellbeing (r = -0.928, p = 0.003) as reflected in the quality of life score. Other findings with p values > 0.05 but <<> 0.1 were noted as <&hyphen>œareas needing further exploration.<&hyphen> Such areas for further exploration included: participants who spent more time in light physical activity reported less role limitations due to physical health (r = 0.864, p = 0.059), higher preoperative activity levels related to higher postoperative 6MWT (r = 0.830, p = 0.082), increased body mass index related to a decrease in postoperatively 6MWT (r = -0.869, p = 0.056). Implications: Exploring the relationship between preoperative activity levels and post-surgical outcomes could provide insight optimizing interventions before surgery to improve surgical success and rehab outcomes.

Full textAbstract:
Traffic signs, which are extremely important for traffic safety, aims to regulate traffic by providing information about the characteristics of road and road environment for drivers. The success of traffic signs mainly rely on the easy comprehensibility of its meaning in a short time. Further more, today&rsquo<br>s global economies and transportation systems emphasize the need for more universial traffic signs which was the main motivation of two main treaties on traffic signs<br>Vienna Convetion in 1968 and European Aggreement Treaty in 1971, which are signed and followed by Turkey. For an effort to increase traffic safety, a Subcommittee of the Turkish Highway Traffic Safety (THTS) Council requested the determination of comprehensibility of critical signs with higher probability of impact on traffic safety selected by a group of experts from engineers and law enforcement agencies in a survey study. The survey questionnaire included 30 selected traffic signs (including two prohibition signs omitting oblique bar recently changed as a part of the European Union Participation Process) and 9 control group signs, a total of 39 traffic signs, and driver characteristic questions, such as gender, age, educational background, etc. to reveal insights about a) the level of comprehensibility of different groups of traffic signs and and b) driver characteristics that may affect the comprehensibility of these signs.
A pilot study in the city of Ankara is conducted over a sample of 1,478 surveys. Answers for the meaning of each sign are coded using a scale of five (opposite, wrong, no comment, partially correct and correct responses). The results showed that the control group signs have very high comprehensibility as expected, while some of the critical signs were not known much, or mistaken for others, even mistaken for opposite meanings. The certain loss of comprehensibility of the traffic signs changed recently is seen in the comparative analysis of the signs before and after the change, as well as significant shift towards an opposite meaning. The significance of driver characteristics (gender, education, occupation etc.) affecting the comprehensibility of the traffic signs varies among traffic signs and characteristics. As the result of this study, (THTS) Council decided to support traffic and driver education more and mass promotion of mis- or un-comprehended signs without searching for more local solutions or versions.

Full textAbstract:
Papua New Guinea has been classified by the World Health Organisation as an area where clinical vitamin A deficiency (VAD) exists. This is at variance with the experience of the local physicians who do not encounter classical VAD in clinical practice. This pilot study was carried out to resolve this contradiction, since many suggestions have been made to fortify foods with Vitamin A. If done in the absence of concrete data to back up this classification, it could take the focus away from the real problem as well as potentially create problems of Vitamin A toxicity. Therefore, answers from this study could have far reaching implications in a country such as PNG, which has high childhood mortality and limited financial and manpower resources. The objective of this study was to determine the vitamin A status and identify risk factors of VAD in children aged 6 months to 6 years in a rural area of Papua New Guinea. The survey was carried out in the Ramu region of Madang province. Households and children were randomly selected and standard questionnaires were used to collect information about diet, previous illnesses and night blindness. The weight and height of all children was recorded and an ocular and physical examination carried out by trained personnel. In addition, haemoglobin estimation and examination of blood films for malaria parasites was carried out in all the children. In a randomly selected number of children, estimations of serum retinol and other micronutrient levels were carried out. Results: A total of 609 children were enrolled in the study. Biochemical parameters were studied in 106 of them .The mean age of the children was 35 months. Possible night blindness was reported in 4 children. No xerophthalmia was seen. The prevalence of serum retinol levels ( 0.7 (mol/L (WHO suggested cut off values for subclinical VAD) was 10.3%. Anthropometric indicators indicated a high proportion of the children had stunting and wasting or both. Analysis of dietary patterns, maternal literacy, food availability and other surrogate indicators indicated that the population is at mild-moderate risk of developing VAD. In conclusion, no evidence of clinical vitamin A deficiency was found. Subclinical vitamin A deficiency seemed to occur in this population at a level of mild-moderate public health importance. Further studies need to be carried out to assess the situation in different areas in PNG before policy decisions can be made with regards to mass vitamin A supplementation.

Full textAbstract:
During vestibular schwannoma surgery a large proportion of patients will lose their hearing. While there have been several papers investigating the mechanism behind this loss of auditory function, the exact pathophysiological mechanisms remain relatively elusive.
The present study aimed to document the patterns of electrophysiological auditory responses during retrosigmoid vestibular schwannoma surgery. In particular, we aimed to determine whether the site of auditory impairment in individual cases was predominantly cochlea or neural.
Auditory function was monitored intraoperatively in two patients who underwent unilateral vestibular schwannoma surgery via the retrosigmoid approach at St George’s Hospital in Christchurch, and Dunedin Public Hospital. A combination of electrocochleography and direct eighth nerve monitoring techniques were used to monitor the auditory evoked potentials from the cochlea and cochlear nerve during the course of the surgery. Auditory brainstem response recordings were obtained from the second participant due to the technical difficulties in the primary electrophysiological techniques.
Technical difficulties faced during the surgical procedure prevented the recording of both electrocochleography and direct eighth nerve monitoring potentials from each of the participants. As a consequence of this, we were unable to draw any conclusions about the site of iatrogenic injury in each surgery. Despite the insufficient recordings of auditory function, the technical and practical knowledge acquired during the course of this pilot study has established a foundation upon which the continuing research may build.

Full textAbstract:
<p> Women who undergo immediate mastectomy for breast cancer experience tremendous anxiety when faced with breast reconstruction and are often conflicted regarding which type of breast reconstruction to choose. This pilot study aimed to analyze the impact of a decision aid, adapted from Stanford University Breast Center, on decisional conflict in women with newly diagnosed breast cancer seeking breast reconstruction. Twenty newly-diagnosed breast cancer patients seeking breast reconstruction at a large academic healthcare center were randomized into two groups. Comparisons were made between women who reviewed the standard educational materials prior to initial consultation, and women who reviewed these materials and then reviewed a decision aid brochure at initial consultation and two weeks post consultation, utilizing the Decisional Conflict Scale. Technical issues halted data collection after only nine participants completed the study. Although no reliable findings could be interpreted from such a small sample size, the results suggest the decision aid as a valuable tool for patient education. Nurses may gain increased awareness of the emotional conflicts faced by newly diagnosed breast cancer patients when making decisions for breast reconstruction.</p><p>

Full textAbstract:
Fingertip amputation injuries are common in all ages. Conservatively treated fingertips can regenerate skin and soft tissues to form a functionally and cosmetically excellent new fingertip. Little is known about this ability that, in humans, is confined to the fingertips. Even less is known about the role of the bacteria that regularly colonize these wounds without negative impact on regeneration and healing.
As an alternative to surgery, self-adhesive film dressings are commonly used to establish a wet chamber around the injury. These dressings leak malodorous wound fluid eventually until the wound is dry. Having that into consideration, we have therefore developed a silicone finger cap that forms a mechanically protected, wet chamber around the injury for optimal regeneration conditions. It contains a puncturable reservoir for excess wound fluid, which can be thus routinely analyzed for diagnostic and research purposes.
This study protocol explains the first randomized controlled trial (RCT) on the semiocclusive treatment of fingertip amputations in both children and adults comparing traditional film dressings with the novel silicone finger cap. Being the first RCT using 2 medical devices not yet certified for this indication, it will gather valuable information for the understanding of fingertip regeneration and the design of future definitive studies.

Este estudo piloto teve como objetivo avaliar os efeitos da ETCC em pacientes com queixa de parestesia em ramos do nervo mandibular. Seis pacientes com parestesia referida na topografia do ramo alveolar inferior (uni ou bilateral), com sintomas iniciados após cirurgia bucomaxilofacial, receberam 10 sessões de ETCC (2 mA, 20 min). A avaliação sensitiva composta pelo teste de sensibilidade tátil com o estesiômetro Semmes-Weinstein e pelo teste térmico com solução spray -50° C foi realizada previamente ao tratamento e após a quinta e a décima estimulação, em 24 pontos na topografia de inervação do ramo em estudo. Houve melhora significativa na sensibilidade no teste tátil nas regiões hipoestésicas, com a terceira avaliação significativamente diferente da primeira (p-valor= 0,0015), mas não diferente da segunda (p-valor=0,1932).

Six patients had paresthesia of inferior alveolar nerve (unilateral or bilateral) and symptoms that began after maxillofacial surgery. They received 10 sessions of tDCS (2 mA, 20 min). The sensory evaluation was conducted prior to the treatment, after the fifth and after the tenth application in 24 points in the branch innervation of topography study. The evaluation was composed by tactile sensitivity test with the Semmes-Weinstein esthesiometer and thermal test with spray solution -50 ° C. There was significant improvement in the sensitivity during the tactile test in hypoesthesia regions, with the third evaluation significantly different from the first (p-value = 0.0015), but not different from the second evaluation (p-value = 0.1932). In the thermal test, the participants recognized a larger number of cold areas in the course of ratings (p-value = 0.05). The use of tDCS seemed to improve the tactile and thermal sensitivity of paresthesia, as well as the relief of paresthesias caused by oral and maxillofacial surgery.

Previous issue date: 2013-05-29<br>Conselho Nacional de Desenvolvimento Científico e Tecnológico<br>The wide availability of water resources in the Amazon has propitiated the implantation of hydropower plants (HPP), resulting in negative environmental impacts in nature and consequently to society. Currently, there are 17 hydroelectric dams in operation in the Brazilian Amazon, among them the Balbina HPP, located in the municipality of Presidente Figueiredo, Amazonas, whose reservoir flooded 2360 km ² and attracted population to its margins, giving origin to communities. In this context, in order to investigate alternatives of integrated management of hydroelectric reservoirs in the Amazon arises the PIRAHIBA Project (Integrated Planning of Hydroelectric Reservoirs in the Amazon Basin), developed by the Interdisciplinary Core for Energy, Environment and Water of the Federal University of Amazonas. This work presents the methodological procedures for the characterization of pilot communities located around the reservoir of Balbina HPP, from local experiences, of the use of GIS techniques and aiming at integrated management of hydric resource. The studies were carried out in four pilot communities (Vila de Balbina, Fé em Deus, Boa União e Novo Rumo), located in two pilot regions, one downstream and one upstream of dam and far between approximately 100 km, taking into view of the time constraints and resource and the restrictions of use and occupation of land - conservation units and indigenous area. Thus, were developed three modalities of intervention of surveys in loco - high, medium and low, aiming: characterize land and water uses by the pilot communities, identify instruments of integrated and participative management existing on site, and build/update maps of pilot communities. These surveys resulted in the generation of data about the pilot communities, essential to the deployment of a digital database and georeferenced of HPP Balbina Reservoir, in the self-knowledge and in the participation these communities, in the proposal of a model of participatory management of HPP Balbina Reservoir and integrated with the advice of the Environmental Protection Area Cave Maroaga and Biological Reserve Uatumã, the Interinstitutional Committee of integrated Management of HPP Balbina Reservoir (CIGIR BALBINA), where should be proposed and discussed studies, plans, programs, projects and actions related the use of this reservoir and groundwater located in its surroundings, as well as programs in water quality monitoring, regulating and compatibilizing multiple uses, as establishes the National Water Resources Policy and in view of local specificities. It was observed that the pilot communities owned differences between them: while the Vila de Balbina have control and orderly occupation, with standardized lots, 38 communitarian equipment and 14 urban; the Community Fé em Deus is the result of random occupation with only one communitarian equipment and three urban. Thus, to validate the methodological procedures of high, medium and low intervention, the application of GIS techniques and procedures in the characterization of Amazonian realities, and the implantation of CIGIR BALBINA for creation of discussion space and participative and integrated management of water resources in the region. Therefore, it is expected that this methodology can be replicated, making it a powerful tool for management of hydropower reservoirs in the Amazon.<br>A grande disponibilidade de recursos hídricos na Amazônia tem propiciado a implantação de usinas hidrelétricas (UHE), resultando em impactos ambientais negativos na natureza e, consequentemente, para a sociedade. Atualmente, existem 17 usinas hidrelétricas em operação na Amazônia brasileira, dentre elas a UHE Balbina, localizada no município de Presidente Figueiredo, Amazonas, cujo reservatório inundou 2.360 km² e atraiu populações para suas margens, dando origem às comunidades. Neste contexto, com o intuito de investigar alternativas de gestão integrada de reservatórios de usinas hidrelétricas na Amazônia, surge o Projeto PIRAHIBA (Planejamento Integrado de Reservatórios em Hidrelétricas da Bacia Amazônica), desenvolvido pelo Núcleo Interdisciplinar de Energia, Meio Ambiente e Água da Universidade Federal do Amazonas. Este trabalho apresenta os procedimentos metodológicos para caracterização de comunidades-piloto localizadas no entorno do Reservatório da UHE Balbina, a partir de vivências locais, do uso de técnicas de geoprocessamento e visando a gestão integrada do recurso hídrico. Os estudos foram desenvolvidos em quatro comunidades-piloto (Vila de Balbina, Fé em Deus, Boa União e Novo Rumo), localizadas em duas regiões-piloto, uma a jusante e outra a montante da barragem e distantes entre si aproximadamente 100 km, tendo em vista as limitações de tempo e de recursos e as restrições de uso e ocupação do solo locais unidades de conservação e área indígena. Assim, foram desenvolvidas três modalidades de intervenção dos levantamentos in loco alta, média e baixa visando: caracterizar usos do solo e da água pelas comunidades-piloto; identificar instrumentos de gestão integrada e participativa existentes no local; e, construir/atualizar os mapas das comunidades-piloto. Esses levantamentos resultaram na geração de dados sobre as comunidades-piloto, essenciais à implantação de uma base de dados digital e georreferenciada do Reservatório da UHE Balbina; no autoconhecimento e na participação dessas comunidades; na proposta de um modelo de gestão participativo do Reservatório da UHE Balbina e integrado aos conselhos da Área de Proteção Ambiental Caverna do Maroaga e da Reserva Biológica Uatumã, o Comitê Interinstitucional de Gestão Integrada do Reservatório da UHE Balbina (CIGIR BALBINA), onde deverão ser propostos e discutidos estudos, planos, programas, projetos e ações relacionadas ao uso desse reservatório e das águas subterrâneas localizadas no seu entorno, bem como programas de monitoramento da qualidade dessas águas, regulando e compatibilizando os usos múltiplos, conforme estabelece a Política Nacional de Recursos Hídricos e tendo em vista as especificidades locais. Observou-se que as comunidades-piloto possuíam diferenças entre si: enquanto a Vila de Balbina tem controle e ocupação ordenada, com padronização de lotes, 38 equipamentos comunitários e 14 urbanos; a comunidade Fé em Deus resulta de ocupação aleatória com apenas um equipamento comunitário e três urbanos. Dessa forma, validam-se os procedimentos metodológicos de alta, média e baixa intervenção; a aplicação de técnicas e procedimentos de geoprocessamento na caracterização de realidades amazônicas; e, a implantação do CIGIR BALBINA para criação de espaço de discussão e de gestão participativa e integrada de recursos hídricos na região. Portanto, espera-se que essa metodologia possa ser replicada, tornando-se uma poderosa ferramenta para gestão de Reservatórios de Hidrelétricas na Amazônia.

Full textAbstract:
High doses of insulin are required to prevent the hyperglycemic response to open heart surgery. Insulin has been shown to produce hypoaminoacidemia during coronary artery bypass graft (CABG) surgery. The present study investigated the effect of high-dose insulin therapy on whole body protein and glucose metabolism in patients undergoing CABG surgery using stable isotope tracers [6,6-2H2]glucose and L-[1-13C]-leucine. Hyperinsulinemic-normoglycemic clamp was used to deliver high-dose insulin. The primary objective was to establish a protocol and to assess the feasibility of using stable isotope tracers after cardiac surgery while continuously infusing high-dose insulin. The effect of high-dose insulin on protein breakdown, synthesis and oxidation and glucose turnover was evaluated.Fifteen patients were recruited to the study, seven in the control group receiving standard glycemic control and eight in the insulin group receiving the hyperinsulinemic-normoglycemic clamp. Isotopic plateaus of L-[1-13C]leucine, [6,6-2H2]glucose and expired 13CO2 were attained in all patients in both groups with a coefficient of variance <5%. Protein breakdown and synthesis both decreased in patients who received high-dose insulin, while protein oxidation remained the same, resulting in a negative protein balance regardless of treatment group. Endogenous glucose production was almost completely suppressed by the administration of high-dose insulin and 20% dextrose solution. The hyperinsulinemic-normoglycemic clamp is a metabolic intervention that when used in the perioperative setting of cardiac surgery, has significant effects on whole body protein breakdown.<br>Lors de chirurgies pour pontage aorto-coronarien, l'utilisation de hautes doses d'insuline est habituellement nécessaire pour prévenir l'augmentation de la glycémie en réponse au stress chirurgical. Il a été démontré que l'administration d'insuline induit une hypoaminoacidémie chez ces patients. La présente étude a pour but d'évaluer les effets de l'administration de hautes doses d'insuline sur le métabolisme des protéines et du glucose par l'usage d'isotopes stables pour ce type d'intervention chirurgicale. Les isotopes utilisés étaient le [6,6-2H2]glucose et la L-[1-13C]leucine. L'objectif principal était de vérifier s'il est possible de faire le suivi postopératoire de ces marqueurs isotopiques en présence de hautes doses d'insuline, et ce afin d'établir un protocole. Les effets de ces hautes doses d'insuline sur la lyse, la synthèse et l'oxydation protéique ainsi que les effets sur le métabolisme du glucose ont été évalués. Quinze sujets ont été recrutés, soit sept dans le groupe témoin recevant le traitement habituel de contrôle de glycémie, et les huit autres dans le groupe d'étude soumis à des hautes doses d'insuline. Les plateaux du [6,6-2H2]glucose, de la L-[1-13C]leucine et du 13CO2 ont été obtenus pour tous les candidats des deux groupes, avec un coefficient de variance < 5%. La lyse et la synthèse protéiques des patients recevant de hautes concentrations d'insuline ont toutes deux diminuées alors que l'oxydation, quant à elle, est restée la même. Un bilan de protéines négatif a été obtenu quelque soit le groupe de traitement. La production endogène de glucose a pratiquement été abolie par l'administration de grande quantité d'insuline et de dextrose 20%. Cette intervention métabolique, lorsqu'utilisée dans le contexte de chirurgies cardiaques, a des effets significatifs sur le métabolisme global des protéines et du glucose des patients.

Full textAbstract:
This study investigated the impact of open heart surgery (Coronary Artery Bypass Graft, Heart Valve Replacement, or Left Ventricular Assist Device placement) on cognition, functional performance, and mood in the three months following surgery. The Montreal Cognitive Assessment (MoCA), Kettle Test (KT), Physical Self Maintenance Scale (PSMS), and Hospital Anxiety and Depression Scale (HD) measured global cognition, functional cognition, functional performance, and mood states, respectively.
Thirteen male participants (ages 38 – 75) completed assessments at four time points -- when they were scheduled for surgery, within one week prior to surgery, before hospital discharge after surgery, and three months after surgery. ANOVA analyses were conducted on overall raw mean scores taken at these time points. Correlational analysis compared changes in cognition and functional performance of daily activities for this group. Effect size estimations and power analyses were conducted to estimate sample sizes needed for adequately powered subsequent study. Two measures (KT and PSMS) were adequately powered at 95% for the study sample. Functional cognition as measured by the KT improved significantly after surgery and surpassed baseline within three months after surgery. Functional performance as measured by the PSMS declined significantly after surgery but returned to baseline within three months after surgery. Global cognition as measured by the MoCA did not change, was not correlated with other measures, and was below norms at all time points. Mood states as measured by the HADS did not change and were above norms at all time points.
This study had a small sample, only male participants, and one pooled group that did not allow for group comparisons. Two measures were self-reported, which may have impacted results due to responses biases. Despite these limitations, this is one of the first studies to track and compare both cognitive and functional performance changes over time. As such, this study may help practitioners and researchers improve and prioritize assessment and treatment options for individuals with cognitive and functional performance deficits after open heart surgery.

Full textAbstract:
Obesity is an increasing problem, with bariatric surgery as one of the main treatment modalities. Patients undergoing surgical intervention appear to receive little psychosocial education and support; support that has the potential to positively affect their health related quality of life (HRQOL) post operatively. No standardised pre operative education for bariatric surgery patients exists within the United Kingdom. Additionally, no research explores the impact of psychosocial education on post-operative HRQOL. Given the impact that obesity and bariatric surgery have on HRQOL, alongside the high incidence of psychological disorders in this population, there is need for research and service improvement in this area. This research study uses a sequential mixed methods approach to develop and test a pre operative group psychosocial educational course, in a controlled clinical trial. The initial feasibility stage highlighted methodological flaws. These were considered and revised before proceeding to a pilot study. Qualitative research was used to explore the perceptions and experiences of pre operative education in post-bariatric surgery candidates. Three main themes were identified relating to changes in their post-operative HRQOL, and surgical preparation: realities of surgery, psychosocial support, and tips and tricks. Key findings highlighted the importance of measuring HRQOL in terms of physical, mental and social health from the patient’s perspective, and how post operatively, psychosocial health is important. Guilt and shame around accessing bariatric surgery was also raised as an issue, particularly associated with guilt of spending NHS money on obesity treatment. Findings from the qualitative work informed the development of the educational course. A final pilot study was conducted using the improved educational course and methodological revisions highlighted from the feasibility study. The results of the pilot suggest that a larger-scale clinical trial to investigate the impact of pre operative psychosocial education on HRQOL using the methods and intervention testing in this study is warranted.

Particular parts of the project 'Uniform Education System for Expert Activities' are listed and described in this dissertation. Legal approaches to the issue of expert activities in selected European countries were mapped on the basis of researches. The fact that the current legal regulation of expert activities in the Czech Republic does not include the obligation of the lifelong learning of experts, does not specify the ways and forms of verifying of qualification requirements before appointing to the office, and also does not provide for the further educating after the registering on the list of experts, is seen as a problematic situation. The suggested system is divided in two basic parts: before registering the expert on the list of experts, focusing on the qualification requirements and the way of their verification by administrative authorities, and after appointing to the office and registering to the central list of experts, focusing on lifelong learning during the whole time of practising of the profession, as well as on the form and content. Some basic methods of sociological survey (especially introductory seminars and questionnaire surveys) were used as the information source. These dates were evaluated and applicable conclusions were compiled and integrated into in more detail described components parts of the suggested education system, in which also the already existing training courses and workshops were taken in consideration. For the purpose of regular verifying of expert's professional qualification, a credit system was developed, as well as the periodicity of verifying of the expert's professional qualification and the form of record keeping in the Index of Expert's Professionalism.

碩士<br>國防醫學院<br>航太醫學研究所<br>91<br>Introduction: Researches revealed that the flying skill and survival rate in air combats of pilots are strongly associated with the visual acuity and visual functions. However, the visual functions in our Air Force were not surveyed completely. Purpose: Epidemiological investigation of the visual acuity will be conducted to determine the prevalence rate of myopia and presbyopia in pilots, and to observe the risk factors related to these refractive errors. Materials and Methods: The subjects were rated pilots composing 166 members, which were divided into three groups: Aerotransport (AT), Low-G fighter (LG), High-G fighter (HG) .The age was ranged from 24 to 51 years old. In this study, we examined the subjects using four visual parameters. Visual acuity was assessed with the projective Snellen’s chart, the refractive error was determined by the auto kerato-refractometer, the presbyopia was detected using the trial lens set, and the contrast sensitivity function was assessed by the contrast sensitivity chart box. Results: (1) Visual acuities below 1.0 in three groups (AT, LG and HG) were 16.3%, 7%, and 11.8%, respectively. The presbyopes over 0.5 D were 22.5%, 2%, and 7.9%, respectively. Also, the percentages of corrective lenses required were 40.0%, 10.0%, and 18.4%, respectively. (2)Additionally, we analyzed the visual functions of the fourth grade cadets of Air Force Academy and discovered that 64% of the cadets were disqualified for advanced flight training due to visual problems. Conclusion: The study indicates that there is a large proportion of corrective lenses required in rated pilots (almost 21%). Among these subjects, the prevalence rates of refractive errors are particularly high in AT group (16.3% myopia and 22.5% presbyopia). Thus, the prospective researches might be focused on the factors which affecting myopia and presbyopia in different groups of rated pilots. In the contrast sensitivity function, the age factor plays an important role was also noted. When these most factors are discovered in this study, the proper policy of visual standard in pilots, then, may be formulated in the near future.

Global polar bear (Ursus maritimus) population numbers are expected to decline steadily over the next 50 years. A noninvasive genetic survey of polar bear numbers may be a useful addition to traditional aerial capture mark recapture (CMR) surveys undertaken throughout the Canadian polar bear population. We attempted a pilot study of noninvasive genetic survey techniques in M’Clintock Channel between May-June 2006-2009. Throughout the survey, we compared our values to the most recent (CMR) survey, conducted by Taylor et al. (2006) between March-June 1998-2000 where 133 cubs, sub-adults and adults were tagged. A total population size of 300 bears was estimated from this aerial CMR survey (Taylor et al. 2006). We found noninvasive sampling stations are sufficient for the capture of a large amount of data on individual bears in an area. Across 4 years, we collected a total of 300 hair samples, and found between 59 and 82 individual bears entered our sampling stations, depending on the stringency of our identification parameters. We estimated genotyping error from duplicated samples, and found this was low (range: 0%-6%), but large enough to not be ignored. There appeared to be a discrepancy between the capture ratio of male adult bears; the CMR survey (1998-2000) captured 25% male bears, while we estimated approximately 64% of our captured bears were male. We felt the most likely explanation of this result is that our traps have a sex bias. However, further research is required to confirm this hypothesis. On the whole, our methods are very important for the management of polar bears, but more research must be done before it can be fully implemented.<br>Thesis (Master, Biology) -- Queen's University, 2010-12-23 15:35:50.16

Full textAbstract:
Trabalho Final do Mestrado Integrado em Medicina Dentária apresentado à Faculdade de Medicina<br>Introdução: A ansiedade dentária denota um estado de apreensão em relação ao tratamento dentário que, sendo uma problemática comum na população infantil, é por vezes transversal aos pais e Médicos dentistas. Embora seja uma entidade abstrata têm sido utilizadas várias técnicas que permitem avaliá-la, sendo a Children’s Fear Survey Schedule-Dental Subscale e a escala de Frankl dois exemplos. A possibilidade de existir uma associação entre ansiedade e o desenvolvimento de problemas comportamentais ainda é uma dinâmica em estudo e sem resultados conclusivos. Objetivos: Avaliar o nível de ansiedade em Odontopediatria e compreender a relação entre os relatos obtidos a partir das crianças e as percepções, tanto dos seus cuidadores, quanto de estudantes de Medicina Dentária. Em paralelo pretende-se analisar uma potencial associação entre a ansiedade e o comportamento da criança durante o tratamento.Materiais e Métodos: Foi realizada uma pesquisa bibliográfica na base de dados PubMed com as palavras-chave: “Dental anxiety”, “Frankl scale”, “Children's Fear Survey Schedule - Dental Subscale”, seletivamente conjugadas pelo operador booleano "AND" e limitada a publicações entre 2007-2017, em inglês e com resumo disponível. Concomitantemente foram aleatoriamente selecionadas 12 crianças para a realização de um estudo piloto às quais foram aplicadas duas escalas, a Children's Fear Survey Schedule - Dental Subscale e a escala de Frankl. Os respetivos cuidadores (n=12) responderam à primeira escala, bem como estudantes do 5º ano de Medicina Dentária (n=4). A avaliação do comportamento foi realizada pelo estudante e por uma Odontopediatra.Resultados: Foram selecionadas 37 referências, maioritariamente estudos clínicos, adicionando-se 13 por pesquisa cruzada. Do estudo piloto os resultados mais relevantes indicaram que, no geral, as crianças foram classificadas como “não ansiosas”; os pais sobrestimaram o nível de ansiedade dos filhos, mas a sua própria ansiedade não pareceu influenciar a percepção que têm acerca das crianças; os estudantes foram os que melhor percepcionaram o nível de ansiedade dos pacientes. A escala de Frankl mostrou-se uma ferramenta de fácil utilização, com resultados consistentes inter-observadores. Não se observou uma relação de causalidade entre ansiedade dentária e comportamento durante o tratamento.Conclusões: Os níveis de ansiedade relatados pelos diferentes sujeitos foram distintos, não se verificando no geral uma associação relevante entre eles. A utilização das duas escalas em associação não permitiu concluir se o nível de ansiedade determina, ou não, o desenvolvimento de problemas comportamentais. O Médico dentista poderá recorrer a estas escalas, não devendo porém basear a abordagem exclusivamente nos resultados daí advindos.<br>Introduction: Dental anxiety indicates a state of apprehension towards dental treatment, which is a common problem in children and, sometimes, it is transversal to parents and dentists. Although it is an abstract concept, several techniques have been used to assess it, with the Children's Fear Survey Schedule-Dental Subscale and the Frankl scale being two examples. The possibility of anxiety and development of behavioral problems being associated is still a dynamic study, but the results are still inconclusive. Objectives: To evaluate the level of anxiety in Pediatric Dentistry and to understand the relationship between children self-reports and the caregivers and Dentistry student’s perceptions about this problem. In parallel, we aim to study if there is an association between anxiety and child behavior during the dental appointment.Methods: An electronic database search was performed in the PubMed / Medline database using pre-defined keywords, selectively combined through the boolean operator “AND”. The research was limited to articles published between 2007 and 2017, in English, with abstract available. Beyond that, 12 children were randomly selected for a pilot study, to which two scales were applied, the Children's Fear Survey Schedule - Dental Subscale and the Frankl scale. Their caregivers (n=12) also completed the first scale, as well as the senior students of Dentistry (n=4). A student and a Pediatric Dentist carried out behavior rating.Results: From the electronic research, 37 references were selected, mostly clinical studies and 13 references were included from cross-search. The most relevant results from pilot study indicate that, in general, children are classified as "non-anxious". Parents overestimated their children's anxiety level, but their own anxiety did not seem to influence their perception about children. The students were those who better perceived the children’s anxiety levels. The Frankl scale proved to be an easy-to-use tool with consistent inter-observer results. Dental anxiety and behavior during treatment seemed to be two realities poorly dependent.Conclusions: The anxiety levels reported by the different subjects were different and in general there was no relevant relationship between them. The two scales in association did not allow us to conclude if the level of anxiety determines, or not, the development of behavioral problems. The Dentist may use these scales, but should not base the approach exclusively on the results accomplished.
