    2015-01-01

    Using a technique based on quantum teleportation, we simplify the most general adaptive protocols for key distribution, entanglement distillation and quantum communication over a wide class of quantum channels in arbitrary dimension. Thanks to this method, we bound the ultimate rates for secret key generation and quantum communication through single-mode Gaussian channels and several discrete-variable channels. In particular, we derive exact formulas for the two-way assisted capacities of the bosonic quantum-limited amplifier and the dephasing channel in arbitrary dimension, as well as the secret key capacity of the qubit erasure channel. Our results establish the limits of quantum communication with arbitrary systems and set the most general and precise benchmarks for testing quantum repeaters in both discrete- and continuous-variable settings.

    Full Text Available The last Hungarian repeat station survey was completed between October 2010 and February 2011. Declination, inclination and the total field were observed using one-axial DMI fluxgate magnetometer mounted on Zeiss20A theodolite and GSM 19 Overhauser magnetometer. The magnetic elements of the sites were reduced to the epoch of 2010.5 on the basis of the continuous recordings of Tihany Geophysical Observatory. In stations located far from the reference observatory, the observations were carried out in the morning and afternoon in order to decrease the effect of the distant temporal correction. To further increase the accuracy, on-site dIdD variometer has also been installed near the Aggtelek station, in the Baradla cave, during the survey of the easternmost sites. The paper presents the technical details and the results of our last campaign. The improvement of the accuracy of the temporal reduction by the use of the local variometer is also reported.

    The use of simple sequence repeats (SSRs), or microsatellites, as genetic markers has become popular due to their abundance and variation in length among individuals. In this study, we investigated linkage groups (LGs) in the woodland strawberry (Fragaria vesca) and demonstrated variation in the abundances, densities, and relative densities of mononucleotide, dinucleotide, and trinucleotide repeats. Mononucleotide, dinucleotide, and trinucleotide repeats were more common than longer repeats in all LGs examined. Perfect SSRs were the predominant SSR type found and their abundance was extremely stable among LGs and chloroplasts. Abundances of mononucleotide, dinucleotide, and trinucleotide repeats were positively correlated with LG size, whereas those of tetranucleotide and hexanucleotide SSRs were not. Generally, in each LG, the abundance, relative abundance, relative density, and the proportion of each unique SSR all declined rapidly as the repeated unit increased. Furthermore, the lengths and frequencies of SSRs varied among different LGs.

    The purpose of this paper is to demonstrate the use of the general linear model (GLM) in problems with repeated measures on a dependent variable. Such problems include pretest-posttest designs, multitrial designs, and groups by trials designs. For each of these designs, a GLM analysis is demonstrated wherein full models are formed and restrictions…

    Several theories exist to explain the source of the bright, millisecond duration pulses known as fast radio bursts (FRBs). If the progenitors of FRBs are non-cataclysmic, such as giant pulses from pulsars, pulsar-planet binaries, or magnetar flares, FRB emission may be seen to repeat. We have undertaken a survey of the fields of eight known FRBs from the High Time Resolution Universe survey to search for repeating pulses. Although no repeat pulses were detected the survey yielded the detection of a new FRB, described in Petroff et al. (2015a). From our observations we rule out periodic repeating sources with periods P $\\leq$ 8.6 hours and rule out sources with periods 8.6 < P < 21 hours at the 90% confidence level. At P $\\geq$ 21 hours our limits fall off as ~1/P. Dedicated and persistent observations of FRB source fields are needed to rule out repetition on longer timescales, a task well-suited to next generation wide-field transient detectors.

  6. Meter Accuracy Seafloor Geodesy using Repeated Multibeam Surveys

    DeSanto, J. B.; Sandwell, D. T.

    2014-12-01

    Ship-board multibeam surveys are a useful tool in measuring tectonic deformation of the seafloor, having been used to measure the ~50 m of surface slip along the Japan trench during the 2011 Tohoku-Oki earthquake with an uncertainty of 20 m (Fujiwara et al, 2011, Science). In this study, we investigate the improvement in positioning accuracy obtainable when comparing multibeam and sidescan surveys repeated along the same track to within 1/10 of the critical baseline and taken at a slow ship speed of 1 knot. We compare two surveys of the Juan de Fuca Ridge axis fitting these criteria with two coincident surveys of the Cocos Ridge, taken at 11 knots. Both pairs of surveys were collected using a Simrad EM120 sonar system aboard the RV Roger Revelle. We find the multibeam surveys of the Juan de Fuca ridge axis sufficient to measure displacements accurate to better than 2 m, a marked improvement over the 50 m accuracy of the Cocos ridge surveys. Likewise, we can measure displacement accurate to 2 m using the sidescan data from the Juan de Fuca surveys. This accuracy is sufficient to observe meter-level horizontal movements on the deep ocean associated with large earthquakes and landslides.

    Full Text Available A review of the literature indicates that food scientistsand health authorities in several countries, especiallymember countries of the European Union, are still veryconcerned about the potential health hazards ofoxidized products and lipid polymers formed inrepeatedly-used deep frying oils. During the fryingprocess at temperatures of 170° – 200°C, steam formedfrom moisture in the food being fried help volatileproducts rise to the surface of the frying medium andinto the kitchen atmosphere, imparting a mixture offried-flavours and off-flavours. The non-volatilecompounds formed, however, gradually build up in theoil as it is being repeatedly-used for food fryingoperations. These non-volatiles, primarily “polarcompounds” (PC and to a lesser extent lipid polymers,get absorbed into fried foods and eventually end up inour body system. Available local data suggests thatdeep-frying oil samples obtained from food hawkers andthose produced under simulated deep-frying conditionsin the laboratory, are generally safe as they contain PCwithin safe limits and rarely exceed the upper limit(UL of 25%. This contrasts with the situation in someEuropean countries where a very high proportion offrying oil samples collected from fast-food restaurantswere reported to contain PC exceeding this UL.Appropriately, promotion of Hazard Analysis andCritical Control Points (HACCP certification andgazetting of food regulations to limit the PC content infrying oils have been introduced in these countries toprotect the health of consumers. Meanwhile, simplegadgets/test kits are available commercially to monitorthe quality of the frying oil. This would greatly assistkitchen supervisors at restaurants and franchised friedfood outlets to know when best to change a batch offrying oil before the ULs of frying oil quality arebreached.

    Full Text Available We study the effects on results of participants completing a survey more than once, a phenomenon known as farming. Using data from a real social science study as a baseline, three strategies that participants might use to farm are studied by Monte Carlo simulation. Findings show that farming influences survey results and can cause both statistical hypotheses testing Type I (false positive and Type II (false negative errors in unpredictable ways.

    The expansion of a tandemly repeated trinucleotide sequence, CAG, is the mutational mechanism for several human genetic diseases. We present a generally applicable PCR amplification method using a fluorescently labelled locus specific primer flanking the CAG repeat together with paired primers amplifying from multiple priming sites within the CAG repeat. Triplet repeat primed PCR (TP PCR) gives a characteristic ladder on the fluorescence trace enabling the rapid identification of large pathogenetic CAG repeats that cannot be amplified using flanking primers. We used our method to test a cohort of 183 people from myotonic dystrophy families including unaffected subjects and spouses. Eighty five clinically affected subjects with expanded alleles on Southern blot analysis were all correctly identified by TP PCR. This method is applicable for any human diseases involving CAG repeat expansions.

  13. Analysis of the repeatability of time-lapse 3d vsp multicomponent surveys, delhi field

    Science.gov (United States)

    Carvalho, Mariana Fernandes de

    Delhi Field is a producing oil field located in northeastern Louisiana. In order to monitor the CO2 sweep efficiency, time-lapse 3D seismic data have been acquired in this area. Time-lapse studies are increasingly used to evaluate changes in the seismic response induced by the production of hydrocarbons or the injection of water, CO2 or steam into a reservoir. A 4D seismic signal is generated by a combination of production and injection effects within the reservoir as well as non-repeatability effects. In order to get reliable results from time-lapse seismic methods, it is important to distinguish the production and injection effects from the non-repeatability effects in the 4D seismic signal. Repeatability of 4D land seismic data is affected by several factors. The most significant of them are: source and receiver geometry inaccuracies, differences in seismic sources signatures, variations in the immediate near surface and ambient non-repeatable noise. In this project, two 3D multicomponent VSP surveys acquired in Delhi Field were used to quantify the relative contribution of each factor that can affect the repeatability in land seismic data. The factors analyzed in this study were: source and receiver geometry inaccura- cies, variations in the immediate near surface and ambient non-repeatable noise. This study showed that all these factors had a significant impact on the repeatability of the successive multicomponent VSP surveys in Delhi Field. This project also shows the advantages and disadvantages in the use of different repeata- bility metrics, normalized-root-mean-square (NRMS) difference and signal-to-distortion ratio (SDR) attribute, to evaluate the level of seismic repeatability between successive time-lapse seismic surveys. It is observed that NRMS difference is greatly influenced by time-shifts and that SDR attribute combined with the time-shift may give more distinct and representative repeatability information than the NRMS difference.

    To describe, explore, and compare organisational routines for repeat prescribing in general practice to identify contributors and barriers to safety and quality. Ethnographic case study. Four urban UK general practices with diverse organisational characteristics using electronic patient records that supported semi-automation of repeat prescribing. 395 hours of ethnographic observation of staff (25 doctors, 16 nurses, 4 healthcare assistants, 6 managers, and 56 reception or administrative staff), and 28 documents and other artefacts relating to repeat prescribing locally and nationally. Potential threats to patient safety and characteristics of good practice. Observation of how doctors, receptionists, and other administrative staff contributed to, and collaborated on, the repeat prescribing routine. Analysis included mapping prescribing routines, building a rich description of organisational practices, and drawing these together through narrative synthesis. This was informed by a sociological model of how organisational routines shape and are shaped by information and communications technologies. Results Repeat prescribing was a complex, technology-supported social practice requiring collaboration between clinical and administrative staff, with important implications for patient safety. More than half of requests for repeat prescriptions were classed as "exceptions" by receptionists (most commonly because the drug, dose, or timing differed from what was on the electronic repeat list). They managed these exceptions by making situated judgments that enabled them (sometimes but not always) to bridge the gap between the idealised assumptions about tasks, roles, and interactions that were built into the electronic patient record and formal protocols, and the actual repeat prescribing routine as it played out in practice. This work was creative and demanded both explicit and tacit knowledge. Clinicians were often unaware of this input and it did not feature in policy

  17. Atomic-ensemble-based quantum repeater against general polarization and phase noise

    2011-07-15

    We present a quantum repeater architecture based on atomic ensembles, which is free of polarization and phase noise. With only simple optical elements, we can obtain the uncorrupted entanglement in the noisy channel. Even if the channel suffers from the general polarization and phase noise, the fidelity of transmitted qubits in our protocol can be stable and have no dependence on the noise parameter, which is a significant advantage compared with previous protocols. Moveover, we can even improve the fidelity by using time delayers. The proposed quantum repeater is feasible and useful in the long-distance quantum entanglement distribution and may be promising in other quantum-information applications.

  18. Repeated surveys by acoustic Doppler current profiler for flow and sediment dynamics in a tidal river

    Dinehart, R. L.; Burau, J. R.

    2005-11-01

    A strategy of repeated surveys by acoustic Doppler current profiler (ADCP) was applied in a tidal river to map velocity vectors and suspended-sediment indicators. The Sacramento River at the junction with the Delta Cross Channel at Walnut Grove, California, was surveyed over several tidal cycles in the Fall of 2000 and 2001 with a vessel-mounted ADCP. Velocity profiles were recorded along flow-defining survey paths, with surveys repeated every 27 min through a diurnal tidal cycle. Velocity vectors along each survey path were interpolated to a three-dimensional Cartesian grid that conformed to local bathymetry. A separate array of vectors was interpolated onto a grid from each survey. By displaying interpolated vector grids sequentially with computer animation, flow dynamics of the reach could be studied in three-dimensions as flow responded to the tidal cycle. Velocity streamtraces in the grid showed the upwelling of flow from the bottom of the Sacramento River channel into the Delta Cross Channel. The sequential display of vector grids showed that water in the canal briefly returned into the Sacramento River after peak flood tides, which had not been known previously. In addition to velocity vectors, ADCP data were processed to derive channel bathymetry and a spatial indicator for suspended-sediment concentration. Individual beam distances to bed, recorded by the ADCP, were transformed to yield bathymetry accurate enough to resolve small bedforms within the study reach. While recording velocity, ADCPs also record the intensity of acoustic backscatter from particles suspended in the flow. Sequential surveys of backscatter intensity were interpolated to grids and animated to indicate the spatial movement of suspended sediment through the study reach. Calculation of backscatter flux through cross-sectional grids provided a first step for computation of suspended-sediment discharge, the second step being a calibrated relation between backscatter intensity and sediment

  19. Concordance correlation coefficients estimated by generalized estimating equations and variance components for longitudinal repeated measurements.

    Science.gov (United States)

    Tsai, Miao-Yu

    2017-04-15

    The concordance correlation coefficient (CCC) is a commonly accepted measure of agreement between two observers for continuous responses. This paper proposes a generalized estimating equations (GEE) approach allowing dependency between repeated measurements over time to assess intra-agreement for each observer and inter- and total agreement among multiple observers simultaneously. Furthermore, the indices of intra-, inter-, and total agreement through variance components (VC) from an extended three-way linear mixed model (LMM) are also developed with consideration of the correlation structure of longitudinal repeated measurements. Simulation studies are conducted to compare the performance of the GEE and VC approaches for repeated measurements from longitudinal data. An application of optometric conformity study is used for illustration. In conclusion, the GEE approach allowing flexibility in model assumptions and correlation structures of repeated measurements gives satisfactory results with small mean square errors and nominal 95% coverage rates for large data sets, and when the assumption of the relationship between variances and covariances for the extended three-way LMM holds, the VC approach performs outstandingly well for all sample sizes.

  1. Repeated count surveys help standardize multi-agency estimates of American Oystercatcher (Haematopus palliatus) abundance

    The extensive breeding range of many shorebird species can make integration of survey data problematic at regional spatial scales. We evaluated the effectiveness of standardized repeated count surveys coordinated across 8 agencies to estimate the abundance of American Oystercatcher (Haematopus palliatus) breeding pairs in the southeastern United States. Breeding season surveys were conducted across coastal North Carolina (90 plots) and the Eastern Shore of Virginia (3 plots). Plots were visited on 1–5 occasions during April–June 2013. N-mixture models were used to estimate abundance and detection probability in relation to survey date, tide stage, plot size, and plot location (coastal bay vs. barrier island). The estimated abundance of oystercatchers in the surveyed area was 1,048 individuals (95% credible interval: 851–1,408) and 470 pairs (384–637), substantially higher than estimates that did not account for detection probability (maximum counts of 674 individuals and 316 pairs). Detection probability was influenced by a quadratic function of survey date, and increased from mid-April (~0.60) to mid-May (~0.80), then remained relatively constant through June. Detection probability was also higher during high tide than during low, rising, or falling tides. Abundance estimates from N-mixture models were validated at 13 plots by exhaustive productivity studies (2–5 surveys wk−1). Intensive productivity studies identified 78 breeding pairs across 13 productivity plots while the N-mixture model abundance estimate was 74 pairs (62–119) using only 1–5 replicated surveys season−1. Our results indicate that standardized replicated count surveys coordinated across multiple agencies and conducted during a relatively short time window (closure assumption) provide tremendous potential to meet both agency-level (e.g., state) and regional-level (e.g., flyway) objectives in large-scale shorebird monitoring programs.

    This study analysed the characteristics of respondent and nonrespondent mothers at each stage of a survey procedure, from a initial questionnaire to a reminder letter and two repeated mailings. Of 938 mothers of liveborn children who, while maternity inpatients, received a questionnaire and information about a mail survey to follow 2 months later, 828 completed and returned the initial questionnaire, 708 agreed to participate in the mail survey and were sent the mail questionnaire, and 612 finally completed and returned the questionnaire at 2 months. There were differences between respondents and non-respondents for socio-demographic factors at each stage of the process. The final response rate to the mail questionnaire was higher among mothers who were younger, were breast feeding, and had more education, an occupation and fewer children. The characteristics of late respondents were intermediate between those of early to middle respondents and nonrespondents for age, educational level, breast feeding and occupation. Maternal and infant health varied only slightly according to response status. Repeated mailings increased response and diminished selection. A mail questionnaire after contact in a maternity ward is a cost-effective means of gathering data about a large sample of recent mothers and their children.

    Sesame (Sesamum indicum), an important oil crop, is widely grown in tropical and subtropical regions. It provides part of the daily edible oil allowance for almost half of the world's population. A limited number of co-dominant markers has been developed and applied in sesame genetic diversity and germplasm identity studies. Here we report for the first time a whole genome survey used to develop simple sequence repeat (SSR) markers and to detect the genetic diversity of sesame germplasm. From the initial assembled sesame genome, 23,438 SSRs (≥5 repeats) were identified. The most common repeat motif was dinucleotide with a frequency of 84.24%, followed by 13.53% trinucleotide, 1.65% tetranucleotide, 0.3% pentanucleotide and 0.28% hexanucleotide motifs. From 1500 designed and synthesised primer pairs, 218 polymorphic SSRs were developed and used to screen 31 sesame accessions that from 12 countries. STRUCTURE and phylogenetic analyses indicated that all sesame accessions could be divided into two groups: one mainly from China and another from other countries. Cluster analysis classified Chinese major sesame varieties into three groups. These novel SSR markers are a useful tool for genetic linkage map construction, genetic diversity detection, and marker-assisted selective sesame breeding.

    Hypothetical bias continues to be a major challenge for stated preference methods. Cheap Talk (CT) has been found to be an effective remedy in some applications, though empirical results are ambiguous. We discuss reasons why CT may fail to effectively remove specific types of hypothetical bias...... in Choice Experiments. We suggest augmenting CT in Choice Experiments with a so-called Opt-Out Reminder (OOR). Prior to each choice set, the OOR explicitly instructs respondents to choose the opt-out alternative, if they find the experimentally designed alternatives too expensive. In an empirical survey we...... find the OOR to significantly reduce total WTP and to some extent also marginal WTP beyond the capability of the CT applied without the OOR. This suggests that the CT practice should be adapted to fit the potentially different decision processes and repeated choices structure of the Choice Experiment...

    2007-01-01

    The purpose of this study was to review data from the province of Alberta, Canada for First Nations children who required more than 1 general anesthesia (GA) procedure for dental surgery from 1996 to 2005. This study was limited to First Nations and Inuit children younger than 18 years old in Alberta who received 2 or more GA procedures to facilitate dental treatment Data spanning 1996 to 2005 were provided from the Alberta Regional Office of First Nations & Inuit Health Branch, Health Canada. The entire database contained claims for 339 children who received repeat GA procedures for rehabilitative dental core. Seventy-six percent received 2 procedures, while the remainder underwent 3 or more surgeries. Twenty-four percent of First Nations children in this cohort were subjected to >2 GA procedures. Retreatment of previously restored teeth was a common observation. The majority of children were treated by general practitioners instead of pediatric dentists. Seventy-four percent who had 2 or more surgeries were treated by general dentists at the time of the first GA procedure. The mean age of children at the time of the first GA procedure was not associated with whether children received 2 or more GA procedures for dental care (P=.07). These data suggest that there may be on over-reliance on GA to treat dental caries for First Notions children in Alberta.

  7. Survey and analysis of simple sequence repeats in the Laccaria bicolor genome, with development of microsatellite markers

    It is becoming clear that simple sequence repeats (SSRs) play a significant role in fungal genome organization, and they are a large source of genetic markers for population genetics and meiotic maps. We identified SSRs in the Laccaria bicolor genome by in silico survey and analyzed their distribution in the different genomic regions. We also compared the abundance and distribution of SSRs in L. bicolor with those of the following fungal genomes: Phanerochaete chrysosporium, Coprinopsis cinerea, Ustilago maydis, Cryptococcus neoformans, Aspergillus nidulans, Magnaporthe grisea, Neurospora crassa and Saccharomyces cerevisiae. Using the MISA computer program, we detected 277,062 SSRs in the L. bicolor genome representing 8% of the assembled genomic sequence. Among the analyzed basidiomycetes, L. bicolor exhibited the highest SSR density although no correlation between relative abundance and the genome sizes was observed. In most genomes the short motifs (mono- to trinucleotides) were more abundant than the longer repeated SSRs. Generally, in each organism, the occurrence, relative abundance, and relative density of SSRs decreased as the repeat unit increased. Furthermore, each organism had its own common and longest SSRs. In the L. bicolor genome, most of the SSRs were located in intergenic regions (73.3%) and the highest SSR density was observed in transposable elements (TEs; 6,706 SSRs/Mb). However, 81% of the protein-coding genes contained SSRs in their exons, suggesting that SSR polymorphism may alter gene phenotypes. Within a L. bicolor offspring, sequence polymorphism of 78 SSRs was mainly detected in non-TE intergenic regions. Unlike previously developed microsatellite markers, these new ones are spread throughout the genome; these markers could have immediate applications in population genetics.

    More than 27,000 Australians currently live with HIV. Most of these people have access to quality clinical care and antiretroviral treatment (ART) and can expect good general health. However, HIV-related stigma is a problem and many people living with HIV experience poorer than average mental health. Issues of aging are also of increasing concern. This paper describes the methods and sample for the HIV Futures 8 study, a national survey of people living with HIV in Australia that aimed to identify factors that support health and well-being among this population. HIV Futures 8 forms part of a series of cross-sectional surveys (The "HIV Futures" studies) that have been repeated periodically since 1997. In the most recent survey, participants were able to opt into a prospective longitudinal study. HIV Futures 8 was open to people aged over 17 who were living with HIV. Data were collected in 2015/2016 using a self-complete survey that contained approximately 250 items related to physical and mental health, use of ART, HIV exposure and testing, financial security, social connectedness, relationships, life satisfaction, resilience, stigma, use of health and support services, and health literacy. To enable comparison of cross-sectional data over time, questionnaire items were consistent with those used in previous HIV Futures surveys. In HIV Futures 8, participants were invited to volunteer coded information that will allow longitudinal follow-up when participants complete subsequent HIV Futures surveys. The survey was advertised through the networks of HIV organizations, on social media and through HIV clinics and services. HIV Futures 8 was completed by 895 participants. This represents approximately 3.8% of the total number of people living with diagnosed HIV in Australia in 2014. Findings from HIV Futures 8 will contribute important insights into the complexity of factors that support physical and mental well-being among people living with HIV. The findings will also

    The purpose of this study is to examine the relationship between the number of unintended pregnancies and current contraceptive use. This is a secondary analysis of a cross-sectional survey, the 2006-2008 National Survey of Family Growth, which included 4,052 women between the ages of 15 and 44 years. A statistically significant association was found between the nonuse of contraceptives and repeated unintended pregnancies, as well as among those who used an effective contraceptive method and repeated unintended pregnancies. Nurses are encouraged to ask questions about intendedness of pregnancies during women's visits and help women choose appropriate contraceptive methods.

    The ability to quantify the processes driving geomorphic change in river valley margins is vital to geomorphologists seeking to understand the relative role of transport mechanisms (e.g. fluvial, aeolian, and hillslope processes) in landscape dynamics. High-resolution, repeat topographic data are becoming readily available to geomorphologists. By contrasting digital elevation models derived from repeat surveys, the transport processes driving topographic changes can be inferred, a method termed ‘mechanistic segregation.’ Unfortunately, mechanistic segregation largely relies on subjective and time consuming manual classification, which has implications both for its reproducibility and the practical scale of its application. Here we present a novel computational workflow for the mechanistic segregation of geomorphic transport processes in geospatial datasets. We apply the workflow to seven sites along the Colorado River in the Grand Canyon, where geomorphic transport is driven by a diverse suite of mechanisms. The workflow performs well when compared to field observations, with an overall predictive accuracy of 84% across 113 validation points. The approach most accurately predicts changes due to fluvial processes (100% accuracy) and aeolian processes (96%), with reduced accuracy in predictions of alluvial and colluvial processes (64% and 73%, respectively). Our workflow is designed to be applicable to a diversity of river systems and will likely provide a rapid and objective understanding of the processes driving geomorphic change at the reach and network scales. We anticipate that such an understanding will allow insight into the response of geomorphic transport processes to external forcings, such as shifts in climate, land use, or river regulation, with implications for process-based river management and restoration.

    Interest in nephrology careers among internal medicine residents in the United States is declining. Our objective was to assess the impact of the presence of a nephrology fellowship training program on perceptions and career interest in nephrology among internal medicine residents. A secondary objective was to identify commonly endorsed negative perceptions of nephrology among internal medicine residents. This was a repeated cross-sectional survey of internal medicine residents before (Group 1) and 3 years after (Group 2) the establishment of nephrology fellowship programs at two institutions. The primary outcome was the percentage of residents indicating nephrology as a career interest in Group 1 vs. Group 2. Secondary outcomes included the frequency that residents agreed with negative statements about nephrology. 131 (80.9%) of 162 residents completed the survey. 19 (14.8%) residents indicated interest in a nephrology career, with 8 (6.3%) indicating nephrology as their first choice. There was no difference in career interest in nephrology between residents who were exposed to nephrology fellows during residency training (Group 2) and residents who were not (Group 1). The most commonly endorsed negative perceptions of nephrology were: nephrology fellows have long hours/burdensome call (36 [28.1%] of residents agreed or strongly agreed), practicing nephrologists must take frequent/difficult call (35 [27.6%] agreed or strongly agreed), and nephrology has few opportunities for procedures (35 [27.3%] agreed or strongly agreed). More residents in Group 2 agreed that nephrology is poorly paid (8.9% in Group 1 vs. 20.8% in Group 2, P = 0.04), whereas more residents in Group 1 agreed that nephrologists must take frequent/difficult call (40.0% in Group 1 vs. 18.1% in Group 2, P = 0.02). The initiation of a nephrology fellowship program was not associated with an increase in internal medicine residents' interest in nephrology careers. Residents endorsed several negative

    Seafloors of unconsolidated sediment are highly dynamic features; eroding or accumulating under the action of tides, waves and currents. Assessing which areas of the seafloor experienced change and measuring the corresponding volumes involved provide insights into these important active sedimentation processes. Computing the difference between Digital Elevation Models (DEMs) obtained from repeat Multibeam Echosounders (MBES) surveys has become a common technique to identify these areas, but the uncertainty in these datasets considerably affects the estimation of the volumes displaced. The two main techniques used to take into account uncertainty in volume estimations are the limitation of calculations to areas experiencing a change in depth beyond a chosen threshold, and the computation of volumetric confidence intervals. However, these techniques are still in their infancy and, as a result, are often crude, seldom used or poorly understood. In this article, we explored a number of possible methodological advances to address this issue, including: (1) using the uncertainty information provided by the MBES data processing algorithm CUBE, (2) adapting fluvial geomorphology techniques for volume calculations using spatially variable thresholds and (3) volumetric histograms. The nearshore seabed off Warrnambool harbour - located in the highly energetic southwest Victorian coast, Australia - was used as a test site. Four consecutive MBES surveys were carried out over a four-months period. The difference between consecutive DEMs revealed an area near the beach experiencing large sediment transfers - mostly erosion - and an area of reef experiencing increasing deposition from the advance of a nearby sediment sheet. The volumes of sediment displaced in these two areas were calculated using the techniques described above, both traditionally and using the suggested improvements. We compared the results and discussed the applicability of the new methodological improvements

    Full Text Available To assess the genetic diversity and population structure of Lolium species, we used 32 nuclear simple sequence repeat (SSR markers and 7 cytoplasmic gene markers to analyze a total of 357 individuals from 162 accessions of 9 Lolium species. This survey revealed a high level of polymorphism, with an average number of alleles per locus of 23.59 and 5.29 and an average PIC-value of 0.83 and 0.54 for nuclear SSR markers and cytoplasmic gene markers, respectively. Analysis of molecular variance (AMOVA revealed that 16.27 and 16.53% of the total variation was due to differences among species, with the remaining 56.35 and 83.47% due to differences within species and 27.39 and 0% due to differences within individuals in 32 nuclear SSR markers set and 6 chloroplast gene markers set, respectively. The 32 nuclear SSR markers detected three subpopulations among 357 individuals, whereas the 6 chloroplast gene markers revealed three subpopulations among 160 accessions in the STRUCTURE analysis. In the clustering analysis, the three inbred species clustered into a single group, whereas the outbreeding species were clearly divided, especially according to nuclear SSR markers. In addition, almost all Lolium multiflorum populations were clustered into group C4, which could be further divided into three subgroups, whereas Lolium perenne populations primarily clustered into two groups (C2 and C3, with a few lines that instead grouped with L. multiflorum (C4 or Lolium rigidum (C6. Together, these results will useful for the use of Lolium germplasm for improvement and increase the effectiveness of ryegrass breeding.

    A significant component of the Greenland ice sheet's mass wasteage to sea level rise is attributed to the acceleration and dynamic thinning at its tidewater margins. To improve understanding of the rapid mass loss processes occurring at large tidewater glaciers, we conducted a suite of daily repeat aerial surveys across the terminus of Store Glacier, a large outlet draining the western Greenland Ice Sheet, from May to July 2014 (https://www.youtube.com/watch?v=-y8kauAVAfE). A suite flock of Unmanned Aerial Vehicles (UAVs) were equipped with digital cameras, which, in combination with onboard GPS, enabled production of high spatial resolution orthophotos and digital elevation models (DEMs) using standard structure-from-motion techniques. These data provide insight into the short-term dynamics of Store Glacier surrounding the break-up of the sea-ice mélange that occurred between 4 and 7 June. Feature tracking of the orthophotos reveals that mean speed of the terminus is 16 - 18 md-1, which was independently verified against a high temporal resolution time-series derived from an expendable/telemetric GPS deployed at the terminus. Differencing the surface area of successive orthophotos enable quantification of daily calving rates, which significantly increase just after melange break-up. Likewise, by differencing bulk freeboard volume of icebergs through time we could also constrain the magnitude and variation of submarine melt. We calculate a mean submarine melt rate of 0.18 md-1 throughout the spring period with relatively little supraglacial runoff and no active meltwater plumes to stimulate fjord circulation and upwelling of deeper, warmer water masses. Finally, we relate calving rates to the zonation and depth of water-filled crevasses, which were prominent across parts of the terminus from June onwards.

    There is a need in clinical and research settings for a sophisticated, generalized, web based survey tool that supports complex logic, separation of content and presentation, and computable guidelines. There are many commercial and open source survey packages available that provide simple logic; few provide sophistication beyond “goto” statements; none support the use of guidelines. These tools are driven by databases, static web pages, and structured documents using markup languages such as eXtensible Markup Language (XML). We propose a generalized, guideline aware language and an implementation architecture using open source standards.

    Acoustic (AC) and midwater trawl (MT) surveys of spawning cisco (Coregonus artedi) in Lake Superior have been combined with commercial yield to estimate exploitation. To time surveys properly, it is important to understand when adults typically arrive at spawning grounds and how numbers change as the spawning season progresses. We conducted repeat autumn surveys during nighttime hours at coastal sites where commercial roe fisheries occur. Spawner densities increased significantly from October to mid-November, but differences measured at sites sampled from mid- to late-November were comparatively small. Spawners occupied the upper 20–30 m of the water column during mid-November before utilizing a wider range of depths by late-November. We compared repeat AC densities to temporal trends of catch-per-unit-effort (CPUE) in suspended commercial gillnets and found good agreement within sites. Because different gillnet mesh sizes were used in each roe fishery. CPUE and AC density were poorly correlated among sites. We recommend that future surveys be conducted between mid- and late-November, and that MT gear be used to measure cisco densities in the uppermost 10 m of the water column where AC estimates may be conservative. Given the short temporal window for assessing spawner density, we believe both AC-MT and gillnet surveys will be needed to ensure that harvest of different stocks is kept at a sustainable level.

    Future weak lensing surveys will map the evolution of matter perturbations and gravitational potentials, yielding a new test of general relativity on cosmic scales. They will probe the relations between matter overdensities, local curvature, and the Newtonian potential. These relations can be modified in alternative gravity theories or by the effects of massive neutrinos or exotic dark energy fluids. We introduce two functions of time and scale which account for any such modifications in the linear regime. We use a principal component analysis to find the eigenmodes of these functions that cosmological data will constrain. The number of constrained modes gives a model-independent forecast of how many parameters describing deviations from general relativity could be constrained, along with w(z). The modes' scale and time dependence tell us which theoretical models will be better tested.

    Background Burnout is a complex syndrome of emotional distress that can disproportionately affect individuals who work in healthcare professions. Study Design For a national survey of burnout in US general surgery residents, we asked all Accreditation Council for Graduate Medical Education-accredited general surgery program directors to email their general surgery residents an invitation to complete an anonymous, online survey. Burnout was assessed with the Maslach Burnout Inventory; total scores for Emotional Exhaustion (EE), Depersonalization (DP), and Personal Accomplishment (PA) subscales were calculated. Burnout was defined as having a score in the highest tertile for EE or DP or lowest tertile for PA. Chi-square tests and one-way analyses of variance were used to test associations between burnout tertiles for each subscale and various resident and training-program characteristics as appropriate. Results From April–December, 2014, 665 residents actively engaged in clinical training had data for analysis; 69% met the criterion for burnout on at least one subscale. Higher burnout on each subscale was reported by residents planning private practice compared with academic careers. A greater proportion of women than men reported burnout on EE and PA. Higher burnout on EE and DP was associated with greater work hours per week. Having a structured mentoring program was associated with lower burnout on each subscale. Conclusions The high rates of burnout among general surgery residents are concerning given the potential impact of burnout on the quality of patient care. Efforts to identify at-risk populations and to design targeted interventions to mitigate burnout in surgical trainees are warranted. PMID:27238875

    observed melange height with the model of hydrostatic equilibrium, we estimate the mean thickness to be 126 m. Whereas the mean melange elevation did not change appreciably in our study area, from the date observations started on 13 May until it disintegrated 4-8 June, we found daily melange elevation change up to 140 % of the observed mean value when tabular icebergs were added to it. Observations showed this increase in melange thickness halted calving and that calving did not resume until the melange had thinned and returned to the observed mean value. We found the mean daily speed of the melange to be 46 m/day, from 13 May to 4 June, whereas the terminus of the glacier flowed with a mean daily velocity of 16 m/day while the melange was present. The higher mean speed of the melange is explained by the motion of large tabular icebergs, which travelled hundreds of metres into the fjord over the course of a single day. The imagery collected over Store Glacier provide evidence that large tidewater glaciers are stabilized by proglacial ice mélange forming in winter. When melange was present, large calving events strengthened melange by adding to its overall thickness distribution, stopping calving altogether for up to several days following a large calving event, and slowing the flow of the glacier to half of the speed observed the previous day. When the melange was advected suddenly down the fjord, with no apparent weakening, the glacier responded by increasing both flow speed and calving rate simultaneously. The data produced from repeat UAV surveys clearly demonstrates the potential of this new and rapidly advancing method of data collection.

    Snow depth mapping in open areas using close range aerial imagery is just one of the many cases where developments in structure-from-motion and multi-view-stereo (SfM-MVS) 3D reconstruction techniques have been applied for geosciences - and with good reason. Our ability to increase the spatial resolution and frequency of observations may allow us to improve our understanding of how snow depth distribution varies through space and time. However, to ensure accurate snow depth observations from close range sensing we must adequately characterize the uncertainty related to our measurement techniques. In this study, we explore the spatial uncertainties of snow elevation models for estimation of snow depth in a complex alpine terrain from close range aerial imagery. We accomplish this by conducting repeat autonomous aerial surveys over a snow-covered active-rock glacier located in the French Alps. The imagery obtained from each flight of an unmanned aerial vehicle (UAV) is used to create an individual digital elevation model (DEM) of the snow surface. As result, we obtain multiple DEMs of the snow surface for the same site. These DEMs are obtained from processing the imagery with the photogrammetry software Agisoft Photoscan. The elevation models are also georeferenced within Photoscan using the geotagged imagery from an onboard GNSS in combination with ground targets placed around the rock glacier, which have been surveyed with highly accurate RTK-GNSS equipment. The random error associated with multi-temporal DEMs of the snow surface is estimated from the repeat aerial survey data. The multiple flights are designed to follow the same flight path and altitude above the ground to simulate the optimal conditions of repeat survey of the site, and thus try to estimate the maximum precision associated with our snow-elevation measurement technique. The bias of the DEMs is assessed with RTK-GNSS survey observations of the snow surface elevation of the area on and surrounding

    Individual agreement between two measurement systems is determined using the total deviation index (TDI) or the coverage probability (CP) criteria as proposed by Lin (2000) and Lin et al. (2002). We used a variance component model as proposed by Choudhary (2007). Using the bootstrap approach, Choudhary (2007), and generalized confidence intervals, we construct bounds on TDI and CP. A simulation study was conducted to assess whether the bounds maintain the stated type I error probability of the test. We also present a computational example to demonstrate the statistical methods described in the paper.

    Simple sequence repeats (SSRs) or microsatellites, which composed of tandem repeated short units of 1-6 bp, have been paying attention continuously. Here, the distribution, composition and polymorphism of microsatellites and compound microsatellites were analyzed in three available genomes of Candida species (Candida dubliniensis, Candida glabrata and Candida orthopsilosis). The results show that there were 118,047, 66,259 and 61,119 microsatellites in genomes of C. dubliniensis, C. glabrata and C. orthopsilosis, respectively. The SSRs covered more than 1/3 length of genomes in the three species. The microsatellites, which just consist of bases A and (or) T, such as (A)n, (T)n, (AT)n, (TA)n, (AAT)n, (TAA)n, (TTA)n, (ATA)n, (ATT)n and (TAT)n, were predominant in the three genomes. The length of microsatellites was focused on 6 bp and 9 bp either in the three genomes or in its coding sequences. What's more, the relative abundance (19.89/kbp) and relative density (167.87 bp/kbp) of SSRs in sequence of mitochondrion of C. glabrata were significantly great than that in any one of genomes or chromosomes of the three species. In addition, the distance between any two adjacent microsatellites was an important factor to influence the formation of compound microsatellites. The analysis may be helpful for further studying the roles of microsatellites in genomes' origination, organization and evolution of Candida species. Copyright © 2016 Elsevier B.V.

    Ladenburg, Jacob; Olsen, Søren Bøye

    reasons why Cheap Talk may fail to effectively remove hypothetical bias, especially in Choice Experiments. In this light, we suggest augmenting Cheap Talk in Choice Experiments with a so-called Opt-Out Reminder. Prior to each single choice set, the Opt-Out Reminder explicitly instructs respondents...... to choose the opt-out alternative if they find the experimentally designed alternatives too expensive. In an empirical Choice Experiment survey we find the Opt-Out Reminder to significantly reduce total WTP and to some extent also marginal WTP beyond the capability of the Cheap Talk applied without the Opt...... Talk with a dynamic Opt-Out Reminder can be an effective and promising improvement in the ongoing effort to remedy the particular types of hypothetical bias that potentially continue to invalidate Choice Experiment surveys....

    Full Text Available DNA sequencing technologies keep getting faster and cheaper leading to massive availability of entire human genomes. This massive availability calls for better analysis tools with a potential to realize a shift from reactive to predictive medicine. The challenge remains, since the entire human genomes need more space and processing power than that can be offered by a standard Desktop PC for their analysis. A background of key concepts surrounding the area of DNA analysis is given and a review of selected prominent algorithms used in this area. The significance of this paper would be to survey the concepts surrounding DNA analysis so as to provide a deep rooted understanding and knowledge transfer regarding existing approaches for DNA analysis using Burrows-Wheeler transform, Wavelet tree and their respective strengths and weaknesses. Consequent to this survey, the paper attempts to provide some directions for future research.

    Aims and method Community treatment orders (CTOs) are increasingly embedded into UK practice and their use continues to rise. However, they remain highly controversial. We surveyed psychiatrists to establish their experiences and current opinions of using CTOs and to compare findings with our previous survey conducted in 2010. Results The opinions of psychiatrists in the UK have not changed since 2010 in spite of recent evidence questioning the effectiveness of CTOs. Clinical factors (the need for engagement and treatment adherence, and the achievement of adherence and improved insight) remain the most important considerations in initiating and discharging a CTO. Clinical implications Given the accumulating evidence from research and clinical practice that CTOs do not improve outcomes, it is concerning that psychiatrists' opinions have not altered in response, particularly given the implications for patient care.

    The practice of pediatric anesthesia requires a regular update of scientific knowledge and technical skills. To provide the most adequate Continuing Medical Education programs, it is necessary to assess the practices of pediatric anesthesiologists. Thus, the objective of this survey was to draw a picture of the current clinical practices of general anesthesia in children, in France. One thousand one hundred and fifty questionnaires were given to anesthesiologists involved in pediatric cases. These questionnaires collected information on various aspects of clinical practice relative to induction, maintenance, recovery from general anaesthesia and also classical debated points such as children with Upper Respiratory Infection (URI), emergence agitation, epileptoid signs or anaesthetic management of adenoidectomy. Differences in practices between CHG (general hospital), CHU (teaching hospital), LIBERAL (private) and PSPH (semi-private) hospitals were investigated. There were 1025 questionnaires completed. Fifty-five percent of responders worked in public hospitals (CHG and CHU); 77% had a practice that was 25% or less of pediatric cases. In children from 3 to 10 years: 72% of respondents used always premedication and two thirds performed inhalation induction in more than 50% of cases. For induction, 53% used sevoflurane (SEVO) at 7 or 8%. Respondents from LIBERAL used higher SEVO concentrations. Tracheal intubation was performed with SEVO alone (37%), SEVO and propofol (55%) and SEVO with myorelaxant (8%), 93% of respondents used a bolus of opioid. For maintenance, the majority of respondents used SEVO associated with sufentanil; desflurane and remifentanil were more frequently used in CHU. Two thirds of respondents used N(2)O. Depth of anesthesia was commonly assessed by hemodynamic changes (52%), end tidal concentration of halogenated (38%) or automated devices based on EEG (7%). In children with URI, 98% of respondents used SEVO for anesthesia. To control the

We aimed to assess socioeconomic inequalities in stunting prevalence over time. Setting Nationally representative household surveys from 25 low and middle income countries. Design We selected nationally representative surveys carried out since the mid-1990s for which information was available on asset indices and on child anthropometry. We identified twenty-five countries which had at least two surveys over an interval of 10 or more years, totaling 87 surveys. Stunting prevalence was calculated according to wealth quintiles. Absolute and relative inequalities were calculated, and time trends were obtained by regression. Results National prevalence declined significantly in 22 of the 25 countries. In 18 out of 25 countries, relative reductions among the rich than among the poor. Overall, there was no indication that inequalities improved. Striking examples are Nepal, with a 17·0 percent points decline in stunting per decade, but where inequalities increased sharply, and Brazil where stunting fell by 6·7 percent points and inequalities were all but eliminated. Conclusions Global progress in reducing stunting has not been accompanied by improved equity, but countries varied markedly in how successful they were in reducing prevalence among the poorest children. It is important to document how some countries were able to reduce inequalities, so that these lessons can be used to foster global progress, particularly in light of the increased importance of within-country inequalities in the post-2015 agenda.

    Full Text Available Abstract Background Despite considerable efforts to promote and support guideline use, adherence is often suboptimal. Barriers to adherence vary not only across guidelines but also across recommendations within guidelines. The aim of this study was to assess the perceived barriers to guideline adherence among GPs by focusing on key recommendations within guidelines. Methods We conducted a cross-sectional electronic survey among 703 GPs in the Netherlands. Sixteen key recommendations were derived from four national guidelines. Six statements were included to address the attitudes towards guidelines in general. In addition, GPs were asked to rate their perceived adherence (one statement and the perceived barriers (fourteen statements for each of the key recommendations, based on an existing framework. Results 264 GPs (38% completed the questionnaire. Although 35% of the GPs reported difficulties in changing routines and habits to follow guidelines, 89% believed that following guidelines leads to improved patient care. Perceived adherence varied between 52 and 95% across recommendations (mean: 77%. The most perceived barriers were related to external factors, in particular patient ability and behaviour (mean: 30% and patient preferences (mean: 23%. Lack of applicability of recommendations in general (mean: 22% and more specifically to individual patients (mean: 25% were also frequently perceived as barriers. The scores on perceived barriers differed largely between recommendations [minimum range 14%; maximum range 67%]. Conclusions Dutch GPs have a positive attitude towards the NHG guidelines, report high adherence rates and low levels of perceived barriers. However, the perceived adherence and perceived barriers varied largely across recommendations. The most perceived barriers across recommendations are patient related, suggesting that current guidelines do not always adequately incorporate patient preferences, needs and abilities. It may be

    To assess the magnitude of the different causes of anxiety in patients and families, facing surgery. Cross-sectional multicenter national survey recruiting 1,260 participants between patients and companions, analyzing the impact of 14 areas selected based on scientific publications aimed at the general public, concerning patients and/or companions, focused on concern about surgery. Patient sex, age, type of surgery (minor/major) and expected inpatient or ambulatory surgery were analyzed. For the companions sex and age, and relationship to patient were analyzed. In both cases it was assessed based on a unidimensional scale of 0 to 10, with 0 being be minimal cause for concern and 10, maximum. The most prominent have been the fear of the unknown, possible complications, the impact on quality of life, the accuracy of diagnosis and possible malignancy of the disease, as well as anesthesia and pain control. There are significant differences in the involvement of patients and companions; and are also differences by sex and age of the patient; type of surgery (minor/major) and expected hospital admission or not. The patient faces surgery with a number of fears that can be reduced with increased information. Copyright © 2014 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.

    Introduction In the context of malaria elimination, interventions will need to target high burden areas to further reduce transmission. Current tools to monitor and report disease burden lack the capacity to continuously detect fine-scale spatial and temporal variations of disease distribution exhibited by malaria. These tools use random sampling techniques that are inefficient for capturing underlying heterogeneity while health facility data in resource-limited settings are inaccurate. Continuous community surveys of malaria burden provide real-time results of local spatio-temporal variation. Adaptive geostatistical design (AGD) improves prediction of outcome of interest compared to current random sampling techniques. We present findings of continuous malaria prevalence surveys using an adaptive sampling design. Methods We conducted repeated cross sectional surveys guided by an adaptive sampling design to monitor the prevalence of malaria parasitaemia and anaemia in children below five years old in the communities living around Majete Wildlife Reserve in Chikwawa district, Southern Malawi. AGD sampling uses previously collected data to sample new locations of high prediction variance or, where prediction exceeds a set threshold. We fitted a geostatistical model to predict malaria prevalence in the area. Findings We conducted five rounds of sampling, and tested 876 children aged 6–59 months from 1377 households over a 12-month period. Malaria prevalence prediction maps showed spatial heterogeneity and presence of hotspots—where predicted malaria prevalence was above 30%; predictors of malaria included age, socio-economic status and ownership of insecticide-treated mosquito nets. Conclusions Continuous malaria prevalence surveys using adaptive sampling increased malaria prevalence prediction accuracy. Results from the surveys were readily available after data collection. The tool can assist local managers to target malaria control interventions in areas with the

    It was computed the horizontal strain rate field for a sector of the Central-Southern Apennines (Italy) from GPS data collected during yearly repeated campaigns performed from 1994 to 2000 on the GeoModAp (Geodynamic Modeling of the Appennines) geodetic network. Site velocities were obtained starting from the daily coordinates and covariance solutions, using a Kalman filter approach. The residual velocity field with respect to a Eurasian fixed reference frame shows two different prevalent motion trends, NE-ward for the the eastern sector of the network and NW-ward for the western one. The mean strain rate tensor, obtained from a least square inversion method, shows a significant extensional deformation (1.2 x 10{sup -}8 strain/yr) normal to the Apennine chain, in agreement with seismological and neotectonic data. On the basis of the network dimension, of about 250 km, this value gives a well constrained estimate of about 3.0 plus or minus 0.2 mm/yr of the extensional velocity oriented N55E, normal to the chain axis. The results show a transition of the strain rate field from about N-S compression in the Tyrrhenian side to about NE-SW extension toward the Adriatic, which depicts a more complex deformation pattern.

    PURPOSE: This study examines oral health behavioral trends and the development of sociodemographic differences in oral health behaviors among Tanzanian students between 1999 and 2000. METHODS: The population targeted was students attending the Muhimbili University College of Health Sciences (MUCHS) at the University of Dar es Salaam (UDSM), Dar es Salaam, Tanzania. Cross-sectional surveys were conducted and a total of 635 and 981 students, respectively, completed questionnaires in 1999 and 2001. RESULTS: Cross-tabulation analyses revealed that in 1999, the rates of abstinence from tobacco use, and of soft drink consumption, regular dental checkups, and intake of chocolate/candy were 84%, 51%, 48%, and 12%, respectively, among students of urban origin and 83%, 29%, 37%, and 5% among their rural counterparts. The corresponding rates in 2001 were 87%, 56%, 50%, and 9% among urban students and 84%, 44%, 38%, and 4% among rural ones. Multiple logistic regression analyses controlling for sex, age, place of origin, educational level, year of survey, and their interaction terms revealed a significant increase in the rate of soft drink consumption, implementation of oral hygiene measures, and abstinence from tobacco use between 1999 and 2001. Social inequalities observed in 1999, with urban students being more likely than their rural counterparts to take soft drinks and go for regular dental checkups, had leveled off by 2001. CONCLUSION: This study provides initial evidence of oral health behavioral trends, that may be utilized in the planning of preventive programs among university students in Tanzania.

    This article focuses on the data evaluation of non-target high-resolution LC-MS profiles of water samples. Taking into account multiple technical replicates, the difficulties in peak recognition and the related problems of false positive and false negative findings are systematically demonstrated. On the basis of a combinatorial approach, different models involving sophisticated workflows are evaluated, particularly with regard to the repeatability. In addition, the improvement resulting from data processing was systematically taken into consideration where the recovery of spiked standards emphasized that real peaks of interest were barely or not removed by the derived filter criteria. The comprehensive evaluation included different matrix types spiked with up to 263 analytical standards which were analyzed repeatedly leading to a total number of more than 250 injections that were incorporated in the assessment of different models of data processing. It was found that the analysis of multiple replicates is the key factor as, on the one hand, it provides the option of integrating valuable filters in order to minimize the false positive rate and, on the other hand, allows correcting partially false negative findings occurring during the peak recognition. The developed processing strategies including replicates clearly point to an enhanced data quality since both the repeatability as well as the peak recognition could be considerably improved. As proof of concept, four different matrix types, including a wastewater treatment plant (WWTP) effluent, were spiked with 130 isotopically labeled standards at different concentration levels. Despite the stringent filter criteria, at 100 ng L(-1) recovery rates of up to 93% were reached in the positive ionization mode. The proposed model, comprising three technical replicates, filters less than 5% and 2% of the standards recognized at 100 and 500 ng L(-1), respectively and thus indicates the general applicability of the

    reasons why Cheap Talk may fail to effectively remove hypothetical bias, especially in Choice Experiments. In this light, we suggest augmenting Cheap Talk in Choice Experiments with a so-called Opt-Out Reminder. Prior to each single choice set, the Opt-Out Reminder explicitly instructs respondents...... Talk with a dynamic Opt-Out Reminder can be an effective and promising improvement in the ongoing effort to remedy the particular types of hypothetical bias that potentially continue to invalidate Choice Experiment surveys.......Hypothetical bias remains a major problem when valuing non-market goods with stated preference methods. Originally developed for Contingent Valuation studies, Cheap Talk has been found to effectively reduce hypothetical bias in some applications, though empirical results are ambiguous. We discuss...

    Introduction: General practitioners (GPs) are key participants in osteoporosis (OP) management. The aim was to evaluate their adherence to lege artis management of the disease, potential barriers, and to discuss differences observed in comparison with the baseline survey carried out in 2007; the focus was on secondary prevention. Methods: On behalf of two professional associations, 2-round postal survey among randomly selected GPs (>1/4 of all Czech GPs) was performed in 2014. The questionnaire covered areas concerning GP's role in the fight against OP, knowledge about OP, management of OP-related fractures, barriers to the management of OP, system- and patient-related in particular, and availability and use of information sources. Results: The overall questionnaire return rate was 37% (551 respondents); mean age of the respondents was 53 year (37% men). The GP's role in the treatment of OP was rated as essential in 28 and 37% of men and women, respectively (P = 0.012). The guideline for diagnosis and treatment of OP for GPs was considered accessible by 92% of respondents. As much as 60% of the respondents were adherent to the guideline, i.e., used it repeatedly. The knowledge of several risk factors was very good, however, recommended daily intake of calcium was stated correctly by only 41% of respondents, and daily intake of vitamin D by only 40%. Three quarters reported active steps after a fracture: referral to a specialist, life-style recommendations, prescription of calcium/vitamin D supplements. Half of the respondents focus on fall prevention. System-related barriers, such as lack of possibility to prescribe selected drugs (61%) and financial limits set by health insurance company (44%) were most frequently reported. Patient-related barriers were also common, patient's non-adherence (reported by 29%) and patient's reluctance to go to a specialist (18%). Conclusion: GPs adhered to OP management more than in 2007. Knowledge of risk factors and involvement in

    Full Text Available Abstract Background Early identification of permanent hearing impairment in children enables appropriate intervention which reduces adverse developmental outcomes. The UK Government has introduced a universal hearing screening programme for neonates. All involved health professionals, including those in Primary Care, need to be aware of the service to enable them to offer appropriate support to their patients. A programme of information dissemination within Primary Care was therefore undertaken. The aim of the current study was to determine the extent to which the information had reached General Practitioners (GPs, the GPs' preferred mode of dissemination and the sources from which GPs accessed information Methods Postal questionnaire survey of a randomised sample of 1000 GPs in the Phase I pilot sites of the Neonatal Hearing Screening Programme (NHSP. Results Responses were received from 54.2% of the sample. Just under 50% of those responding had received information, 62.2% of respondents said they would like to receive more information and the preferred methods of dissemination were the written word and web-sites to allow access when needed. Few GPs perceive themselves to have a core role in the delivery of the NHSP and thence a need for knowledge in the subject. Many are keen to delegate detail to a third party, usually the health visitor, who has traditionally had responsibility for hearing screening. Conclusions Dissemination efforts for service developments of relevance to GPs should concentrate on advertising a website address via brief but memorable posted literature and/or articles in relevant journals and magazines. The website should be GP-friendly, and have a dedicated area for GPs including information of specific relevance and downloadable information sheets.

    Full Text Available Abstract Background Exposure to second hand smoke (SHS is an important preventable cause of morbidity and mortality in children. We hypothesised that there has been a growth in social inequality in children’s exposure to SHS at home over time. The purpose of this study was to investigate temporal change in smoking in homes including children, focusing on the socioeconomic differences. Methods Data is from a repeated cross-sectional survey, ‘Health Profiles of the Capital Region of Denmark’ conducted in 2007 and 2010, in 29 municipalities. The response rate was 52.3%, in both surveys. Our study included persons aged 25 to 64, living with children ≤15 years of age; N=9,289 in 2007 and 12,696 in 2010. Analyses were weighted for size of municipality and for non-response, which was higher among men and among persons who were younger, had a lower income, were living alone, were unemployed, and/or were of an ethnicity other than Danish. Regression analyses were used to investigate smoking in homes including children across parent/adult education levels, focusing on temporal changes. Results There were significant large socioeconomic differences in both 2007 and 2010. In 2010 it was more than 11 times more likely for a child to be exposed to SHS at home if the parent had very low education than if they were highly educated (p Conclusions Marked social inequalities in children’s exposure to SHS and a significant temporal decrease in exposure, independent of the education level of the parent/adult, were found in repeated large cross-sectional population-based studies. Social disparities have persisted over time, but not increased. Both clinical and population policy interventions will be needed in order to control child SHS exposure. We call for legislative protection of children from tobacco smoke inside their home as a supplement to parental education and support for smoking cessation.

    To assess the reproducibility of respondent-driven sampling (RDS) in obtaining comparable samples across two survey rounds, we conducted integrated bio-behavioral surveillance surveys (IBBSS) using RDS in 2007 and 2011 among men who have sex with men (MSM) on Unguja island in Zanzibar. Differences in the two rounds were assessed by comparing RDS-adjusted population estimates, stratified estimates, and bottleneck plots. Participants in the 2011 survey round were younger (31.4 vs. 9.9% under 19 years old, p < 0.001), more likely to have tested for HIV in the last year (53.7 vs. 10.6%, p < 0.001), and less likely to have injected drugs in the last 3 months (1.0 vs. 23.2%, p < 0.001) compared to participants in the 2007 round. HIV prevalence was 12.3% in 2007 compared to 2.6% in 2011 (p < 0.001). The difference in HIV prevalence persisted after stratifying and adjusting for known differences in the two surveys rounds. Bottleneck plots suggest that recruitment chains were "trapped" in the social networks of MSM who injected drugs to a greater extent in 2007 than in 2011. We conclude that the two rounds of RDS sampled different subsets of the MSM population on Unguja, particularly with respect to inclusion of MSM within the social networks of people who inject drugs. Findings underscore the need to evaluate the reproducibility of RDS in repeated rounds of IBBSS and to develop new sampling methods for key populations at high risk for HIV in order to track the epidemic, develop evidence-based prevention and care programs, and assess their impact.

  3. Methane Seeps in the Gulf of Mexico: repeat acoustic surveying shows highly temporally and spatially variable venting

    Scientists have recognized that natural seeps account for a large amount of methane emissions. Despite their widespread occurrence in areas like the Gulf of Mexico, little is known about the temporal variability and site-scale spatial variability of venting over time. We used repeat acoustic surveys to compare multiple days of seep activity and determine the changes in the locus of methane emission and plume height. The Sleeping Dragon site was surveyed with an EM302 multibeam sonar on three consecutive days in 2014 and 4 days within one week in 2015. The data revealed three distinctive plume regions. The locus of venting varied by 10-60 meters at each site. The plume that exhibited the least spatial variability in venting, was also the most temporally variable. This seep was present in one-third of survey dates in 2014 and three quarters of survey dates in 2015, showing high day-to-day variability. The plume height was very consistent for this plume, whereas the other plumes were more consistent temporally, but varied in maximum plume height detection by 25-85 m. The single locus of emission at the site that had high day-to-day variability may be due to a single conduit for methane release, which is sometimes closed off by carbonate or clathrate hydrate formation. In addition to day-to-day temporal variability, the locus of emission at one site was observed to shift from a point-source in 2014 to a diffuse source in 2015 at a nearby location. ROV observations showed that one of the seep sites that closed off temporarily, experienced an explosive breakthrough of gas, releasing confined methane and blowing out rock. The mechanism that causes on/off behavior of certain plumes, combined with the spatial variability of the locus of methane release shown in this study may point to carbonate or hydrate formation in the seep plumbing system and should be further investigated.

    Located on the Vestfirdir Northwest Fjords), DrangaJokull is the northernmost ice map in Iceland. Currently, the ice cap exceeds 900 m in elevation and covered an area of approx.l46 sq km in August 2004. It was about 204 sq km in area during 1913-1914 and so has lost mass during the 20th century. Drangajokull's size and accessibility for GPS surveys as well as the availability of repeat satellite altimetry profiles since late 2003 make it a good subject for change-detection analysis. The ice cap was surveyed by four GPS-equipped snowmobiles on 19-20 April 2005 and has been profiled in two places by Ice, Cloud. and land Elevation Satellite (ICESat) 'repeat tracks,' fifteen times from late to early 2009. In addition, traditional mass-balance measurements have been taken seasonally at a number of locations across the ice cap and they show positive net mass balances in 2004/2005 through 2006/2007. Mean elevation differences between the temporally-closest ICESat profiles and the GPS-derived digital-elevation model (DEM)(ICESat - DEM) are about 1.1 m but have standard deviations of 3 to 4 m. Differencing all ICESat repeats from the DEM shows that the overall elevation difference trend since 2003 is negative with losses of as much as 1.5 m/a from same season to same season (and similar elevation) data subsets. However, the mass balance assessments by traditional stake re-measurement methods suggest that the elevation changes where ICESat tracks 0046 and 0307 cross Drangajokull are not representative of the whole ice cap. Specifically, the area has experienced positive mass balance years during the time frame when ICESat data indicates substantial losses. This analysis suggests that ICESat-derived elevations may be used for multi-year change detection relative to other data but suggests that large uncertainties remain. These uncertainties may be due to geolocation uncertainty on steep slopes and continuing cloud cover that limits temporal and spatial coverage across the

    This study sought to analyse antimicrobial pressure, indications for treatment, and compliance with treatment recommendations and to identify possible problem areas where inappropriate use could be improved through interventions by the network of the local Swedish Strategic Programme Against Antibiotic Resistance (Strama) groups. Five point-prevalence surveys were performed in between 49 and 72 participating hospitals from 2003 to 2010. Treatments were recorded for 19 predefined diagnosis groups and whether they were for community-acquired infection, hospital-acquired infection, or prophylaxis. Approximately one-third of inpatients were treated with antimicrobials. Compliance with guidelines for treatment of community-acquired pneumonia with narrow-spectrum penicillin was 17.0% during baseline 2003-2004, and significantly improved to 24.2% in 2010. Corresponding figures for quinolone use in uncomplicated cystitis in women were 28.5% in 2003-2004, and significantly improved, decreasing to 15.3% in 2010. The length of surgical prophylaxis improved significantly when data for a single dose and 1 day were combined, from 56.3% in 2003-2004 to 66.6% in 2010. Improved compliance was possibly the effect of active local feedback, repeated surveys, and increasing awareness of antimicrobial resistance. Strama groups are important for successful local implementation of antimicrobial stewardship programs in Sweden.

We examine response bias using data from a postal job satisfaction survey of family doctors. We link all the sampled doctors to an administrative database and so have information on the characteristics of responders and non-responders. Allowing for selection increases the estimate of mean job satisfaction in...

  8. Dissection of thousands of cell type-specific enhancers identifies dinucleotide repeat motifs as general enhancer features.

    Gene expression is determined by genomic elements called enhancers, which contain short motifs bound by different transcription factors (TFs). However, how enhancer sequences and TF motifs relate to enhancer activity is unknown, and general sequence requirements for enhancers or comprehensive sets of important enhancer sequence elements have remained elusive. Here, we computationally dissect thousands of functional enhancer sequences from three different Drosophila cell lines. We find that the enhancers display distinct cis-regulatory sequence signatures, which are predictive of the enhancers' cell type-specific or broad activities. These signatures contain transcription factor motifs and a novel class of enhancer sequence elements, dinucleotide repeat motifs (DRMs). DRMs are highly enriched in enhancers, particularly in enhancers that are broadly active across different cell types. We experimentally validate the importance of the identified TF motifs and DRMs for enhancer function and show that they can be sufficient to create an active enhancer de novo from a nonfunctional sequence. The function of DRMs as a novel class of general enhancer features that are also enriched in human regulatory regions might explain their implication in several diseases and provides important insights into gene regulation.

    This article will discuss the clinician's knowledge of wound assessment based on electronic voting responses gathered at the Journal of Wound Care conference, ''Wound Expo', held in September 2015. Data were gathered on aspects such as demographic data, experience and opinions. Each workshop lasted 45 minutes and they were designed purposely to be interactive and inclusive. The session was repeated ten times over the 2-day period. A total number of 196 delegates participated in the voting and amongst the questions posed they were asked to consider which term most suited their skill set and understanding, that of 'debridement' or 'desloughing'. Of the respondents, 91% stated that they felt most confident in desloughing.

    Full Text Available BACKGROUND: Zinc treatment of childhood diarrhea has the potential to save 400,000 under-five lives per year in lesser developed countries. In 2004 the World Health Organization (WHO/UNICEF revised their clinical management of childhood diarrhea guidelines to include zinc. The aim of this study was to monitor the impact of the first national campaign to scale up zinc treatment of childhood diarrhea in Bangladesh. METHODS/FINDINGS: Between September 2006 to October 2008 seven repeated ecologic surveys were carried out in four representative population strata: mega-city urban slum and urban nonslum, municipal, and rural. Households of approximately 3,200 children with an active or recent case of diarrhea were enrolled in each survey round. Caretaker awareness of zinc as a treatment for childhood diarrhea by 10 mo following the mass media launch was attained in 90%, 74%, 66%, and 50% of urban nonslum, municipal, urban slum, and rural populations, respectively. By 23 mo into the campaign, approximately 25% of urban nonslum, 20% of municipal and urban slum, and 10% of rural under-five children were receiving zinc for the treatment of diarrhea. The scale-up campaign had no adverse effect on the use of oral rehydration salt (ORS. CONCLUSIONS: Long-term monitoring of scale-up programs identifies important gaps in coverage and provides the information necessary to document that intended outcomes are being attained and unintended consequences avoided. The scale-up of zinc treatment of childhood diarrhea rapidly attained widespread awareness, but actual use has lagged behind. Disparities in zinc coverage favoring higher income, urban households were identified, but these were gradually diminished over the two years of follow-up monitoring. The scale up campaign has not had any adverse effect on the use of ORS. Please see later in the article for the Editors' Summary.

  11. A survey of statistics in three UK general practice journal

    2004-12-01

    Full Text Available Abstract Background Many medical specialities have reviewed the statistical content of their journals. To our knowledge this has not been done in general practice. Given the main role of a general practitioner as a diagnostician we thought it would be of interest to see whether the statistical methods reported reflect the diagnostic process. Methods Hand search of three UK journals of general practice namely the British Medical Journal (general practice section, British Journal of General Practice and Family Practice over a one-year period (1 January to 31 December 2000. Results A wide variety of statistical techniques were used. The most common methods included t-tests and Chi-squared tests. There were few articles reporting likelihood ratios and other useful diagnostic methods. There was evidence that the journals with the more thorough statistical review process reported a more complex and wider variety of statistical techniques. Conclusions The BMJ had a wider range and greater diversity of statistical methods than the other two journals. However, in all three journals there was a dearth of papers reflecting the diagnostic process. Across all three journals there were relatively few papers describing randomised controlled trials thus recognising the difficulty of implementing this design in general practice.

  12. A Critical Review of Surveys Emphasizing on Routing in Wireless Sensor Networks—An Anatomization under General Survey Design Framework

    Science.gov (United States)

    2017-01-01

    A large number of routing-related surveys are published so far for Wireless Sensor Networks (WSNs) that exhibit either complete or partial emphasis on routing in WSNs. These surveys classify and discuss the relevant routing protocols published mainly in the fields of classical, energy efficient, secure, hierarchical, geographic, intelligent, Quality of Service (QoS)-based and multipath WSNs. However, to the best of our knowledge, no study is presented so far which may clearly categorize the routing-related survey literature for WSNs.To fill this gap, an effort is made in this paper for presenting an in-depth review of already published routing-related survey literature in WSNs. Our review initially proposes a generalized survey design model and afterwards analyzes the routing-related survey literature in the light of the devised General Survey Design Framework (GSDF). Such an analysis describes the design soundness of the published routing-related surveys. Therefore, our review puts forth an original classification based on the frequency-of-survey-publication and taxonomizes the corresponding routing-related fields into high, medium and low focused areas of survey publication in WSNs. Furthermore, the surveys belonging to each main category are sub-categorized into various sub-classes and briefly discussed according to their design characteristics. On the one hand, this review is useful for beginners who may easily explore the already published routing-related survey literature in WSNs in a single document and investigate it by spending less effort. On the other hand, it is useful for expert researchers who may explore the trends and frequency of writing surveys in different areas of routing in WSNs. The experts may explore those areas of routing which are either neglected or least focused or lack in design soundness as per general survey design framework. In the end, insights and future research directions are outlined and a reasonable conclusion is put forth

    The delivery of general paediatric surgery is changing in Ireland. Fewer paediatric surgical procedures are being performed by newly appointed consultant general surgeons, resulting in increased referrals to the specialist paediatric surgeons of uncomplicated general paediatric surgical problems. We surveyed current higher surgical trainees about their views on provision of paediatric surgical services.

    Full Text Available Jens Georg HansenDepartment of Clinical Epidemiology, Aarhus University Hospital and Aalborg Hospital, Aalborg, DenmarkPurpose: To evaluate whether the ongoing debate over diagnostic problems and treatment choices for acute rhinosinusitis has had any influence on the management of the disease.Methods: We randomly selected 300 Danish general practitioners (GPs from the files of the Research Unit for General Practice at Aarhus University. Invitations to participate and a questionnaire were sent to the GPs by mail.Results: A total of 149 (49% GPs answered the questionnaire. When asked about symptoms, the highest priority was given to sinus pain and signs of tenderness. The most frequent examinations were objective examination of the ear-nose-throat (ENT, palpation of the maxillofacial area, and C-reactive protein point-of-care testing (or CRP rapid test. Nearly all GPs prescribed local vasoconstrictors, and in 70% of cases, antibiotics were prescribed. Phenoxymethylpenicillin was the preferred antibiotic. Use of the CRP rapid test, years in practice, or employment in an ENT department did not have a significant impact on the diagnostic certainty and antibiotic prescribing rate.Conclusion: The clinical diagnoses are based on a few symptoms, signs, and the CRP rapid test. Other examinations, including imaging techniques, are seldom used. Phenoxymethylpenicillin is the preferred antibiotic, and the GPs' diagnostic certainty was 70%.Keywords: general practice, acute rhinosinusitis, diagnosis, treatment, antibiotic

  17. Assessing controls on cross-shelf phytoplankton and suspended particle distributions using repeated bio-optical glider surveys

    Characterizing the space/time variability of bio-optical properties is essential to understand the mechanisms that control cross-shelf phytoplankton and suspended particle distributions in coastal waters. Approximately 400 high-resolution cross-shelf sections of bio-optical properties collected with an oceanographic glider in the coastal Santa Barbara Channel, California, revealed complex relationships among optical properties and environmental conditions. Surface waves were found as a proximate control on suspended sediment variability for both inner and midshelves. Increases in phytoplankton abundances attributed to horizontal advection and upwelling events were observed only on episodic time scales. The lack of all-encompassing linear relationships between environmental forcings and changes in cross-shelf phytoplankton highlights the challenge of decoupling bio-optical signals from their controlling processes in coastal zones where phytoplankton distributions are patchy, and where nearshore and offshore phytoplankton populations and suspended sediments often occupy the same portion of the water column. Clear relationships between runoff and productivity were not observed. Temporal variability of suspended particles and phytoplankton distributions were roughly independent from each other during stratified conditions. Synchronous increases in phytoplankton and suspended sediments were observed when associated with strong upwelling events that may induce mixing and promote productivity. The repeated glider sections illustrated many processes regulating phytoplankton and particle transport in the innershelf and showed the difficulty in establishing general connections between high-frequency changes in optical properties and potential environmental forcings in a complex coastal environment.

  20. Generalized estimators of avian abundance from count survey data

    Directory of Open Access Journals (Sweden)

    Royle, J. A.

    2004-01-01

    Full Text Available I consider modeling avian abundance from spatially referenced bird count data collected according to common protocols such as capture-recapture, multiple observer, removal sampling and simple point counts. Small sample sizes and large numbers of parameters have motivated many analyses that disregard the spatial indexing of the data, and thus do not provide an adequate treatment of spatial structure. I describe a general framework for modeling spatially replicated data that regards local abundance as a random process, motivated by the view that the set of spatially referenced local populations (at the sample locations constitute a metapopulation. Under this view, attention can be focused on developing a model for the variation in local abundance independent of the sampling protocol being considered. The metapopulation model structure, when combined with the data generating model, define a simple hierarchical model that can be analyzed using conventional methods. The proposed modeling framework is completely general in the sense that broad classes of metapopulation models may be considered, site level covariates on detection and abundance may be considered, and estimates of abundance and related quantities may be obtained for sample locations, groups of locations, unsampled locations. Two brief examples are given, the first involving simple point counts, and the second based on temporary removal counts. Extension of these models to open systems is briefly discussed.

    Doctors' continuing professional development (CPD) training needs are known to be strongly influenced by national and local contextual characteristics. Given the changing national demographic profile and government-mandated changes to primary care health care provision, this study aimed to investigate Irish General Practitioners' (GPs) perceptions of, and preferences for, current and future CPD programmes. A cross-sectional questionnaire, using closed- and open-ended questions, was administered to Irish GPs, focusing on training needs analysis; CPD course content; preferred format and the learning environment. The response rate was 719/1000 (71.9%). GPs identified doctor-patient communication as the most important and best-performed GP skill. Discrepancies between perceived importance (high) and current performance (low) emerged for time/workload management, practice finance and business skills. GPs identified clinically-relevant primary care topics and non-clinical topics (stress management, business skills, practice management) as preferences for future CPD. Flexible methods for CPD delivery were important. Gender and practice location (urban or rural) significantly influenced CPD participation and future course preference. The increasing diversity of services offered in the Irish primary care setting, in both clinical and non-clinical areas, should be tailored based to include GP practice location and structure.

    In this article, we argue that past efforts to distinguish among types of intimate partner violence in general survey data have committed a critical error--using data on current spouses to develop operationalizations of intimate terrorism and situational couple violence. We use ex-spouse data from the National Violence Against Women Survey (NVAWS) to develop new operationalizations. We then demonstrate that NVAWS current spouse data contain little intimate terrorism; we argue that this is likely to be the case for all general surveys. In addition, the ex-spouse data confirm past findings regarding a variety of differences between intimate terrorism and situational couple violence, including those predicted by feminist theories.

    Geomagnetic field data from four observatories and annual field surveys between 2005 and 2015 provide a detailed description of Earth's magnetic field changes over South Africa, Namibia and Botswana on time scales of less than 1 year. The southern African area is characterized by rapid changes in the secular variation pattern and lies in close proximity to the South Atlantic Anomaly (SAA) where the geomagnetic field intensity is almost 30 % weaker than in other regions at similar latitudes around the globe. Several geomagnetic secular acceleration (SA) pulses (geomagnetic jerks) around 2007, 2010 and 2012 could be identified over the last decade in southern Africa. We present a new regional field model for declination and horizontal and vertical intensity over southern Africa (Southern African REGional (SAREG)) which is based on field survey and observatory data and covering the time interval from 2005 to 2014, i.e. including the period between 2010 and 2013 when no low Earth-orbiting vector field satellite data are available. A comparative evaluation between SAREG and global field models like CHAOS-5, the CHAMP, Orsted and SAC-C model of the Earth's magnetic field and International Geomagnetic Reference Field (IGRF-12) reveals that a simple regional field model based on a relatively dense ground network is able to provide a realistic representation of the geomagnetic field in this area. We particularly note that a global field model like CHAOS-5 does not always indicate similar short-period patterns in the field components as revealed by observatory data, while representing the general secular variation reasonably well during the time interval without near-Earth satellite vector field data. This investigation further shows the inhomogeneous occurrence and distribution of secular variation impulses in the different geomagnetic field components and at different locations in southern African.

    Due to the increasing numbers of Muslims in Germany(1)--about 4.3 million at the moment--more Muslim patients are medicated in the practices of family doctors. Their heterogeneous cultural and religious backgrounds are nontheless unknown and unfamiliar for the treating general practitioner. Based on the daily experiences of the latter and in order to capture their development of intercultural competence, in the present study a brainwriting with general practitioners was conducted to record their spontaneous associations with Muslim patients. Individually and without exchange 90 general practitioners (66 male, 24 female) listed subjective thoughts regarding "Muslim patients" on a prepared sheet of paper. Additionally, sex, age, number of years as physician in a private practice and the frequency of treatment of Muslim patients in their own practice were requested. The content of the notes were evaluated using MAXQDA and were clustered in the categories of "language", "company", "violence", "men"/"women", "psychosomatic medicine", "compliance", "understanding of illness", "physical examination" and "head scarf". The ideas listed show that the majority of interviewed general practitioners regarded the treatment of Muslim patients as difficult. They associate Muslim patients with communication problems, a different type of disease understanding and a fear of contact, which hampers the examination situation. Less frequently, positive associations and unproblematic examination situations were noted. Due to a lack of knowledge about cultural and religious contexts Muslim patients are often described by using stereotypes. This underlines the necessity to foster intercultural competences and self-reflection in daily practice and its systematic inclusion in medical education. © Georg Thieme Verlag KG Stuttgart · New York.

    Yesilova, Abdullah; Yilmaz, Ayhan

    In this study, the Poison regression, negative binomial regression and generalized estimating equations were applied to the repeated measurements based on count data obtained from the sexual behaviors of ram lambs. Negative binomial regression was more effective to handle the over dispersion that causes bias in parameter estimations in Poison regression. The generalized estimating equations were used for analyzing repeated categorical data. GEE estimates were obtained by using the exchangeable working correlation. As a result of GEE analyses, it was concluded that flehmen lip curl response, tail raising, mount duration, vocalization and weight of the ram lamb were statistically important (p<0.05) for mount frequent. However, the anogenital sniff found be not significant.

    2007-05-01

    Full Text Available Abstract Background Extensive computational and database tools are available to mine genomic and genetic databases for model organisms, but little genomic data is available for many species of ecological or agricultural significance, especially those with large genomes. Genome surveys using conventional sequencing techniques are powerful, particularly for detecting sequences present in many copies per genome. However these methods are time-consuming and have potential drawbacks. High throughput 454 sequencing provides an alternative method by which much information can be gained quickly and cheaply from high-coverage surveys of genomic DNA. Results We sequenced 78 million base-pairs of randomly sheared soybean DNA which passed our quality criteria. Computational analysis of the survey sequences provided global information on the abundant repetitive sequences in soybean. The sequence was used to determine the copy number across regions of large genomic clones or contigs and discover higher-order structures within satellite repeats. We have created an annotated, online database of sequences present in multiple copies in the soybean genome. The low bias of pyrosequencing against repeat sequences is demonstrated by the overall composition of the survey data, which matches well with past estimates of repetitive DNA content obtained by DNA re-association kinetics (Cot analysis. Conclusion This approach provides a potential aid to conventional or shotgun genome assembly, by allowing rapid assessment of copy number in any clone or clone-end sequence. In addition, we show that partial sequencing can provide access to partial protein-coding sequences.

    2011-10-01

    Full Text Available Abstract Background Considering the changes in dental healthcare, such as the increasing assertiveness of patients, the introduction of new dental professionals, and regulated competition, it becomes more important that general dental practitioners (GDPs take patients' views into account. The aim of the study was to compare patients' views on organizational aspects of general dental practices with those of GDPs and with GDPs' estimation of patients' views. Methods In a survey study, patients and GDPs provided their views on organizational aspects of a general dental practice. In a second, separate survey, GDPs were invited to estimate patients' views on 22 organizational aspects of a general dental practice. Results For 4 of the 22 aspects, patients and GDPs had the same views, and GDPs estimated patients' views reasonably well: 'Dutch-speaking GDP', 'guarantee on treatment', 'treatment by the same GDP', and 'reminder of routine oral examination'. For 2 aspects ('quality assessment' and 'accessibility for disabled patients' patients and GDPs had the same standards, although the GDPs underestimated the patients' standards. Patients had higher standards than GDPs for 7 aspects and lower standards than GDPs for 8 aspects. Conclusion On most aspects GDPs and patient have different views, except for social desirable aspects. Given the increasing assertiveness of patients, it is startling the GDP's estimated only half of the patients' views correctly. The findings of the study can assist GDPs in adapting their organizational services to better meet the preferences of their patients and to improve the communication towards patients.

  11. Location matters: trends in inequalities in child mortality in Indonesia. Evidence from repeated cross-sectional surveys.

    Directory of Open Access Journals (Sweden)

    Andrew Hodge

    Full Text Available Considerable improvements in life expectancy and other human development indicators in Indonesia are thought to mask considerable disparities between populations in the country. We examine the existence and extent of these disparities by measuring trends and inequalities in the under-five mortality rate and neonatal mortality rate across wealth, education and geography.Using data from seven waves of the Indonesian Demographic and Health Surveys, direct estimates of under-five and neonatal mortality rates were generated for 1980-2011. Absolute and relative inequalities were measured by rate differences and ratios, and where possible, slope and relative indices of inequality. Disparities were assessed by levels of rural/urban location, island groups, maternal education and household wealth.Declines in national rates of under-five and neonatal mortality have accorded with reductions of absolute inequalities in clusters stratified by wealth, maternal education and rural/urban location. Across these groups, relative inequalities have generally stabilised, with possible increases with respect to mortality across wealth subpopulations. Both relative and absolute inequalities in rates of under-five and neonatal mortality stratified by island divisions have widened.Indonesia has made considerable gains in reducing under-five and neonatal mortality at a national level, with the largest reductions happening before the Asian financial crisis (1997-98 and decentralisation (2000. Hasty implementation of decentralisation reforms may have contributed to a slowdown in mortality rate reduction thereafter. Widening inequities between the most developed provinces of Java-Bali and those of other island groupings should be of particular concern for a country embarking on an ambitious plan for universal health coverage by 2019.

    Peter P. Groenewegen

    2016-01-01

    Full Text Available Background. The participation of general practitioners (GPs is essential in research on the performance of primary care. This paper describes the implementation of a large, multicountry study in primary care that combines a survey among GPs and a linked survey among patients that visited their practice (the QUALICOPC study. The aim is to describe the recruitment procedure and explore differences between countries in the participation rate of the GPs. Methods. Descriptive analyses were used to document recruitment procedures and to assess hypotheses potentially explaining variation in participation rates between countries. Results. The survey was implemented in 31 European countries. GPs were mainly selected through random sampling. The actual implementation of the study differed between countries. The median participation rate was 30%. Both material (such as the payment system of GPs in a country and immaterial influences (such as estimated survey pressure are related to differences between countries. Conclusion. This study shows that the participation of GPs may indeed be influenced by the context of the country. The implementation of complex data collection is difficult to realize in a completely uniform way. Procedures have to be tuned to the context of the country.

    2007-01-01

    Background In 1996 the guideline 'The Red Eye' was first published by the Dutch College of General Practitioners. The extent to which general practitioners adhere to this guideline is unclear. Recently, data on the management of infectious conjunctivitis by general practitioners became available from the Second Dutch National Survey of General Practice. We measured the age-specific incidence of infectious conjunctivitis, described its management by Dutch general practitioners, and then compared these findings with the recommendations made in the guideline. Methods In 2001, over a 12-month period, data from all patient contacts with 195 general practitioners were taken from electronic medical records. Registration was episode-oriented; all consultations dealing with the same health problem were grouped into disease episodes. Data concerning all episodes of infectious conjunctivitis (ICPC-code F70 and sub codes) were analysed. Results Over one year, 5,213 new and recurrent episodes of infectious conjunctivitis were presented to general practitioners from a population of N = 375,899, resulting in an overall incidence rate of 13.9 per 1000 person-years, varying from more than 80/1000 py in children up to one-year old, to less than 12/1000 py in children over the age of 4. Topical ophthalmic ointments were prescribed in 87% of the episodes, of which 80% was antibiotic treatment. Fusidic acid gel was most frequently prescribed (69%). In most episodes general practitioners did not adhere to the guideline. Conclusion In 2001, the management of infectious conjunctivitis by Dutch general practitioners was not in accordance with the recommendations of the consensus-based guideline published five years previously, despite its wide distribution. In 2006 this guideline was revised. Its successful implementation requires more than distribution alone. Probably the most effective way to achieve this is by following a model for systemic implementation. PMID:17868475

    Full Text Available Abstract Background In 1996 the guideline 'The Red Eye' was first published by the Dutch College of General Practitioners. The extent to which general practitioners adhere to this guideline is unclear. Recently, data on the management of infectious conjunctivitis by general practitioners became available from the Second Dutch National Survey of General Practice. We measured the age-specific incidence of infectious conjunctivitis, described its management by Dutch general practitioners, and then compared these findings with the recommendations made in the guideline.

    Education is by far the strongest predictor of whether a non-economist will share the economic beliefs of the average economist. (Caplan, 2001) Is the effect of education as large as it seems? Or is education largely a proxy for cognitive ability? Using data from the General Social Survey (GSS), we show that the estimated effect of education…

    Background The role of the GP in the care of sexually transmitted infections (STIs) is unclear. Aim We studied the prevalence of STI related consultations in Dutch general practice in order to obtain insight into the contribution of the GP in STI control. Design of study A descriptive study. Setting The study took place within the framework of the second Dutch National Survey of General Practice in 2001, a large nationally representative population-based survey. Method During 1 year, data of all patient contacts with the participating GPs were recorded in electronic medical records. Contacts for the same health problem were clustered into disease episodes and their diagnosis coded according to the International Classification of Primary Care. All STI and STI related episodes were analysed. Results In total, 1 524 470 contacts of 375 899 registered persons in 104 practices were registered during 1 year and 2460 STI related episodes were found. The prevalence rate of STI was 39 per 10 000 persons and of STI/HIV related questions 23 per 10 000. More than half of all STIs were found in highly urbanised areas and STIs were overrepresented in deprived areas. Three quarters of all STIs diagnosed in the Netherlands are made in general practice. An important number of other reproductive health visits in general practice offer opportunities for meaningful STI counselling and tailored prevention. Discussion GPs contribute significantly to STI control, see the majority of patients with STI related symptoms and questions and are an important player in STI care. In particular, GPs in urban areas and inner-city practices should be targeted for accelerated sexual health programmes. PMID:16464323

    The hAT transposons, very abundant in all kingdoms, have a common evolutionary origin probably predating the plant-fungi-animal divergence. In this paper we present their general characteristics. Members of this superfamily belong to Class II transposable elements. hAT elements share transposase, short terminal inverted repeats and eight base-pairs duplication of genomic target. We focus on hAT elements in Drosophila, especially hobo. Its distribution, dynamics and impact on genome restructuring in laboratory strains as well as in natural populations are reported. Finally, the evolutionary history of hAT elements, their domestication and use as transgenic tools are discussed.

    Full Text Available Abstract Background International trade regulations require that countries document their livestock's sanitary status in general and freedom from specific infective agents in detail provided that import restrictions should be applied. The latter is generally achieved by large national serological surveys and risk assessments. The paper describes the basic structure and application of a generic stochastic model for risk-based sample size calculation of consecutive national surveys to document freedom from contagious disease agents in livestock. Methods In the model, disease spread during the time period between two consecutive surveys was considered, either from undetected infections within the domestic population or from imported infected animals. The @Risk model consists of the domestic spread in-between two national surveys; the infection of domestic herds from animals imported from countries with a sanitary status comparable to Switzerland or lower sanitary status and the summary sheet which summed up the numbers of resulting infected herds of all infection pathways to derive the pre-survey prevalence in the domestic population. Thereof the pre-survey probability of freedom from infection and required survey sample sizes were calculated. A scenario for detection of infected herds by general surveillance was included optionally. Results The model highlights the importance of residual domestic infection spread and characteristics of different import pathways. The sensitivity analysis revealed that number of infected, but undetected domestic herds and the multiplicative between-survey-spread factor were most correlated with the pre-survey probability of freedom from infection and the resulting sample size, respectively. Compared to the deterministic pre-cursor model, the stochastic model was therefore more sensitive to the previous survey's results. Undetected spread of infection in the domestic population between two surveys gained more

    AIM: To compare the findings of a survey undertaken by us in 2002 regarding steroid premedication given in radiology departments to reduce the risk of adverse reactions in patients at increased risk of intravascular contrast media reactions with a similar survey published in 1994 by R. Seymour et al. The high risk patients considered in our survey were patients with history of asthma, drug allergies, hay fever and eczema. MATERIALS AND METHODS: A total of 225 questionnaires were sent to the consultant in charge for audit for radiology departments from the list given by the Royal College of Radiologists. 175 of the 225 questionnaires were returned (response rate 77.8%) and of these 172 were analysed with respect to the type, dose and duration of steroids. RESULTS: Compared to the survey in 1994, it was found that the number of departments who use steroid cover for all category of risk factors had increased compared to previous survey (73.8% in 2002 versus 55.3% in 1994 (p=0.001). There is now almost universal use of non-ionic contrast 98.8% versus 82.4% in 1994 (p=0.001). There is no agreed policy among radiology departments for the need or the dose or duration of steroid cover. CONCLUSION: Despite the more widespread use of non-ionic contrast media, the use of steroid premedication has increased which is contrary to what is expected as the incidence of adverse reaction to non ionic media is less than ionic contrast media.

    We present the stellar kinematic maps of a large sample of galaxies from the integral-field spectroscopic survey CALIFA. The sample comprises 300 galaxies displaying a wide range of morphologies across the Hubble sequence, from ellipticals to late-type spirals. This dataset allows us to homogeneously extract stellar kinematics up to several effective radii. In this paper, we describe the level of completeness of this subset of galaxies with respect to the full CALIFA sample, as well as the virtues and limitations of the kinematic extraction compared to other well-known integral-field surveys. In addition, we provide averaged integrated velocity dispersion radial profiles for different galaxy types, which are particularly useful to apply aperture corrections for single aperture measurements or poorly resolved stellar kinematics of high-redshift sources. The work presented in this paper sets the basis for the study of more general properties of galaxies that will be explored in subsequent papers of the survey.

    The paper provides a survey of results related to the "$\\kappa$-generalized distribution", a statistical model for the size distribution of income and wealth. Topics include, among others, discussion of basic analytical properties, interrelations with other statistical distributions as well as aspects that are of special interest in the income distribution field, such as the Gini index and the Lorenz curve. An extension of the basic model that is most able to accommodate the special features of wealth data is also reviewed. The survey of empirical applications given in this paper shows the $\\kappa$-generalized models of income and wealth to be in excellent agreement with the observed data in many cases.

    The purpose of this study was to document current practices of dentist anesthesiologists who are members of the American Society of Dentist Anesthesiologists regarding the supplemental use of local anesthesia for children undergoing dental rehabilitation under general anesthesia. A survey was administered via e-mail to the membership of the American Society of Dentist Anesthesiologists to document the use of local anesthetic during dental rehabilitations under general anesthesia and the rationale for its use. Seventy-seven (42.1%) of the 183 members responded to this survey. The majority of dentist anesthesiologists prefer use of local anesthetic during general anesthesia for dental rehabilitation almost always or sometimes (90%, 63/70) and 40% (28/70) prefer its use with rare exception. For dentist anesthesiologists who prefer the administration of local anesthesia almost always, they listed the following factors as very important: "stabilization of vital signs/decreased depth of general anesthesia" (92.9%, 26/28) and "improved patient recovery" (82.1%, 23/28). There was a significant association between the type of practice and who determines whether or not local anesthesia is administered during cases. The majority of respondents favor the use of local anesthesia during dental rehabilitation under general anesthesia.

    Ustilaginoidea virens is the causal agent of rice false smut, causing quantitative and qualitative losses in rice industry. However, the development and application of simple sequence repeat (SSR) markers for genetic diversity studies in U. virens were limited. This study is the first to perform large-scale development of SSR markers of this pathogen at the genome level, to (1) compare these SSR markers with those of other fungi, (2) analyze the pattern of the SSRs, and (3) obtain more informative genetic markers. U. virens is rich in SSRs, and 13,778 SSRs were identified with a relative abundance of 349.7SSRs/Mb. The most common motifs in the genome or in noncoding regions were mononucleotides, whereas trinucleotides in coding sequences. A total of 6 out of 127 primers were randomly selected to be used to analyze 115 isolates, and these 6 primers showed high polymorphism in U. virens. This study may serve as an important resource for molecular genetic studies in U. virens.

    Full Text Available Although the main goal of asthma management guidelines is to achieve and maintain clinical control, reported levels of not well-controlled asthma remain high. The aim of this analysis was to compare the levels of asthma control and the associated impact on patients' health status in Europe in 2006, 2008 and 2010. An additional outcome was the comparison of the burden of asthma with diabetes. Data were obtained from the cross-sectional, self-reported, European National Health and Wellness Surveys conducted in France, Germany, Italy, Spain and the UK. Asthma control (Asthma Control Test™; QualityMetric, Inc., Lincoln, RI, USA and health status (Short Form (SF-12 health survey and the Work Productivity Loss and Activity Impairment questionnaire were assessed. In 2010, the proportion of treated asthma patients assessed as having not well-controlled asthma was 53.5%, compared with 56.6% and 55.0% in 2008 and 2006, respectively. A significant reduction in not well-controlled asthma was observed in Germany between 2006 (72.3% and 2010 (62.5%; p=0.005. Fluctuations in control levels were observed in other countries. For all surveys, having at least well-controlled asthma was associated with a significantly lower number of healthcare contacts in the previous 6 months, better mean±sd SF-12 scores for the physical (data for 2010: not well controlled 39.9±11.38, at least well-controlled 48.0±9.89; p<0.001 and mental (data for 2010: not well-controlled 40.6±10.95, at least well-controlled 45.0±10.91; p<0.001 components, and significantly less impact on Work Productivity Loss and Activity Impairment. Asthma and diabetes were associated with a similar overall negative impact on health status. A substantial proportion of asthmatics remain not well-controlled across five European countries, resulting in a significant impact on health resources and patients' health status. The overall burden of asthma appears to be similar to that of diabetes.

    Bathymetric and velocimetric data were collected six times by the U.S. Geological Survey, in cooperation with the Kansas Department of Transportation, in the vicinity of Amelia Earhart Bridge on U.S. Highway 59 over the Missouri River at Atchison, Kansas. A multibeam echosounder mapping system and an acoustic Doppler current meter were used to obtain channel-bed elevations and depth-averaged velocities for a river reach approximately 2,300 feet long and extending across the active channel of the Missouri River. The bathymetric and velocimetric surveys provide a “snapshot” of the channel conditions at the time of each survey, and document changes to the channel-bed elevations and velocities during the course of construction of a new bridge for U.S. Highway 59 downstream from the Amelia Earhart Bridge. The baseline survey in June 2009 revealed substantial scour holes existed at the railroad bridge piers upstream from and at pier 10 of the Amelia Earhart Bridge, with mostly uniform flow and velocities throughout the study reach. After the construction of a trestle and cofferdam on the left (eastern) bank downstream from the Amelia Earhart Bridge, a survey on June 2, 2010, revealed scour holes with similar size and shape as the baseline for similar flow conditions, with slightly higher velocities and a more substantial contraction of flow near the bridges than the baseline. Subsequent surveys during flooding conditions in June 2010 and July 2011 revealed substantial scour near the bridges compared to the baseline survey caused by the contraction of flow; however, the larger flood in July 2011 resulted in less scour than in June 2010, partly because the removal of the cofferdam for pier 5 of the new bridge in March 2011 diminished the contraction near the bridges. Generally, the downstream part of the study reach exhibited varying amounts of scour in all of the surveys except the last when compared to the baseline. During the final survey, velocities throughout the

    Full Text Available Abstract Background The goal of Roll Back Malaria (RBM is to reduce malaria morbidity and mortality by 50% by the year 2010, and still further thereafter until the disease becomes no more a threat to public health. To contribute to the monitoring and evaluation process of this goal, two surveys were carried out in 2000 and 2003 in households and health facilities in the Kassena-Nankana district, northern Ghana using the RBM-WHO/AFRO monitoring and evaluation tools for malaria control activities. Methods Data were collected from mothers/caretakers on signs/symptoms of the most recent malaria attack for their under five year old children; the management actions that they took and their perception of health services provided at the health facilities, bednet use, antenatal attendance and place of delivery for the most recent pregnancy, malaria prophylaxis during their last pregnancy. Community health workers and herbalist/traditional healers were also interviewed about the types of health services they provide to community members. Results The results revealed a significant improvement in knowledge among mothers/caretakers over the three-year period; this affected caretakers' initial management of illnesses of their young children. The management in terms of the type and dosage of drugs used also improved significantly (p The intensification of malaria control activities and awareness creation in this district over a three year period had started demonstrating positive results towards reducing malaria disease burden. Conclusion Periodic performance assessments through surveys as described and prompt feedback of results to stakeholders in the locality serves as a catalyst to improving malaria control in malaria-endemic countries.

  10. Dynamic Feedbacks Between Flow, Erosion and Evolving River Bank Roughness Revealed Through Repeat High-Resolution Topographic Surveys

    Bank erosion is a key process in fluvial dynamics, with significant fractions of the total sediment load being sourced from river banks. Studies have shown that hydraulic erosion of the bank toe is a driving factor of long term rates of bank retreat. Fluvial bank erosion rates are often quantified using an excess shear stress model where the erosion rate is a function of the boundary shear stress applied by the flow above a critical threshold. Research has shown that the form roughness induced by natural topographic bank features such as slumps, spurs and embayments, is a major component of the spatially-averaged total shear stress. The skin friction component of this shear stress is typically an order of magnitude less than the total, meaning that the form roughness provides an important control on bank erosion rates. However, measuring the relative components of the total shear stress for a natural system is not straightforward. In this research we apply the method of Kean and Smith [2006, J. Geophys. Res., 111(4), F04009, doi:10.1029/2006JF000467] to partition the form and skin drag components of river bank roughness for an eroding bank of the Cecina River in central Italy. This method approximates the form drag component of the roughness along a longitudinal bank profile as a series of user defined Gaussian curves, with the skin friction component estimated through analysis of the deviations of the data from the fitted curves. For our site, a temporal sequence (2003 - 2011) of high-resolution topographic surveys has been collected through a combination of photogrammetry and Terrestrial Laser Scanning. For each survey five vertically equidistant profiles are extracted and analysed alongside DEMs of difference and associated flow data modelled using the distributed hydrological model MOBIDIC. The data are used to explore the dynamic feedbacks that exist between river discharge, bank erosion processes and bank form roughness, revealing insights into the self

    Full Text Available Abstract Background Burnout and intolerance of uncertainty have been linked to low job satisfaction and lower quality patient care. While resilience is related to these concepts, no study has examined these three concepts in a cohort of doctors. The objective of this study was to measure resilience, burnout, compassion satisfaction, personal meaning in patient care and intolerance of uncertainty in Australian general practice (GP registrars. Methods We conducted a paper-based cross-sectional survey of GP registrars in Australia from June to July 2010, recruited from a newsletter item or registrar education events. Survey measures included the Resilience Scale-14, a single-item scale for burnout, Professional Quality of Life (ProQOL scale, Personal Meaning in Patient Care scale, Intolerance of Uncertainty-12 scale, and Physician Response to Uncertainty scale. Results 128 GP registrars responded (response rate 90%. Fourteen percent of registrars were found to be at risk of burnout using the single-item scale for burnout, but none met the criteria for burnout using the ProQOL scale. Secondary traumatic stress, general intolerance of uncertainty, anxiety due to clinical uncertainty and reluctance to disclose uncertainty to patients were associated with being at higher risk of burnout, but sex, age, practice location, training duration, years since graduation, and reluctance to disclose uncertainty to physicians were not. Only ten percent of registrars had high resilience scores. Resilience was positively associated with compassion satisfaction and personal meaning in patient care. Resilience was negatively associated with burnout, secondary traumatic stress, inhibitory anxiety, general intolerance to uncertainty, concern about bad outcomes and reluctance to disclose uncertainty to patients. Conclusions GP registrars in this survey showed a lower level of burnout than in other recent surveys of the broader junior doctor population in both Australia

    Full Text Available Abstract Background Non-coverage of households without a landline telephone is a major concern of telephone survey researchers. Sampling mobile telephone users in national surveys is vital in order to gain access to the growing proportion of households that use mobile telephones extensively or exclusively. The complex logistics of conducting surveys with mobile telephones have been discussed in the literature. This paper outlines the actual challenges encountered during a recent national sexual health survey in Ireland, which utilized a mobile telephone sampling frame to recruit approximately half of the sample. Method The 2010 Irish Contraception and Crisis Pregnancy Survey (ICCP-2010 is a nationally representative sample of adults aged 18-45 years living in Ireland (n = 3002; 1416 recruited by landline telephone and 1586 recruited by mobile telephone. The overall response rate for the survey was 69% (79% for the landline telephone strand; 61% for the mobile telephone strand. All interviews were conducted using computer-assisting telephone interviewing. Results During the 18-week fieldwork period, five main challenges relating to the use of mobile telephones were encountered: (1 explaining to respondents how random digit dialling works in relation to mobile telephones; (2 establishing the respondent's eligibility; (3 calling the respondent with the Caller ID blocked or withheld; (4 calling the respondent when they are in any number of locations or situations; and (5 explaining to respondents the importance of refusal conversion calls for the response rate calculation. Details of how the survey protocols and procedures were monitored and adapted throughout the study to ensure a high response rate are outlined. Conclusion It is undeniably more challenging to recruit respondents using mobile telephones as opposed to landline telephones. Respondents are generally not familiar with being contacted on their personal mobile telephone for the purposes

    General surgery trainees' perceptions regarding their own laparoscopic training remain poorly defined. The objective of this survey was to identify and evaluate learner experiences with laparoscopic procedures in general surgery programs on a national level. Two hundred eighty-four residents were identified and contacted at English-speaking general surgery programs across Canada. Each was asked to complete a web- or paper-based survey regarding their demographics, experiences with basic and advanced minimally invasive surgery (MIS) procedures, and perceived barriers to training. Two hundred fifty-two of 284 (89%) surveyed residents responded. Eighty-seven percent of the residents had access to a skills lab that taught MIS techniques; however, standardized MIS curricula were implemented 53% of the time. Eighty percent of residents felt that skills lab training translated to improved performance in the OR. Although 90% of residents felt that they would be comfortable performing basic laparoscopic procedures, only 8% stated they would be comfortable performing advanced procedures at the end of their training. Moreover, 90% of general surgery residents felt that it was the academic surgical department's responsibility to teach both basic and advanced procedures, and 35% of respondents felt their surgical program was meeting this requirement. Half of the residents felt they had limited opportunity to be a primary surgeon because an MIS fellow was present. There exists a wide disparity between the expectations of residents and their actual experience. The majority of residents are concerned that they will not acquire sufficient laparoscopic skills during their training to perform advanced cases in practice. Additionally, the balance between resident and fellow-level cases needs to be more clearly defined as the majority of respondents identified the presence of a MIS fellow as a negative learning influence. Finally, although most centers had a surgical skills lab, 47% of

    The fourth morbidity survey in England and Wales is based on a population of 473,000 persons registered in 60 practices and cared for by 241 general practitioners. This presentation traces the evolution of morbidity surveys in England and Wales. That evolution has taken place against a background of advancing computer technology and the drift towards a paperless record. It is motivated by an increasing recognition of the need for data from primary health care an a realisation that a structured record is capable of servicing information needs without intermediary data sheets and coding procedures. The primary objectives of the study include assessment of disease prevalence by region, age-sex and social group; and to study trends over time. Morbidity and social data are collected in the practices and all relevant information stored on practice computers. At the end of the recording year, the computerised record for each patient is copied on to disks in an anonymized but uniquely identified form and transferred to the national Office of Population Censuses & Surveys for analysis. During the year, weekly extracts are taken of new episodes of illness in age and sex groupings which provide the basis of the Weekly Returns Service of the Royal College of General Practitioners.

    We present the Advanced Camera for Surveys General Catalog (ACS-GC), a photometric and morphological database using publicly available data obtained with the Advanced Camera for Surveys (ACS) instrument on the Hubble Space Telescope. The goal of the ACS-GC database is to provide a large statistical sample of galaxies with reliable structural and distance measurements to probe the evolution of galaxies over a wide range of look-back times. The ACS-GC includes over 490,000 astronomical sources (stars + galaxies) derived from the AEGIS, COSMOS, GEMS, and GOODS surveys. Galapagos was used to construct photometric (SExtractor) and morphological (Galfit) catalogs. The analysis assumes a single S\\'ersic model for each object to derive quantitative structural parameters. We include publicly available redshifts from the DEEP2, COMBO-17, TKRS, PEARS, ACES, CFHTLS,and zCOSMOS surveys to supply redshifts (spectroscopic and photometric) for a considerable fraction (~71%) of the imaging sample. The ACS-GC includes color po...

    In this study we provide evidence that the transcription factor BCL11B represses expression from the HIV-1 long terminal repeat (LTR) in T lymphocytes through direct association with the HIV-1 LTR. We also demonstrate that the NuRD corepressor complex mediates BCL11B transcriptional repression of the HIV-1 LTR. In addition, BCL11B and the NuRD complex repressed TAT-mediated transactivation of the HIV-1 LTR in T lymphocytes, pointing to a potential role in initiation of silencing. In support of all the above results, we demonstrate that BCL11B affects HIV-1 replication and virus production, most likely by blocking LTR transcriptional activity. BCL11B showed specific repression for the HIV-1 LTR sequences isolated from seven different HIV-1 subtypes, demonstrating that it is a general transcriptional repressor for all LTRs.

  17. Assisted admissions? A national survey of general practitioner experience of involuntary admissions.

    2011-10-01

    The 2001 Mental Health Act introduced in 2006, changed how a patient is admitted involuntarily to a psychiatric unit. This paper reports on a national survey of general practitioners\\' experience implementing the Act. Five hundred and sixty eight (568) GPs completed the survey. Twenty five percent (25%) of respondants had not used it. When used, twenty four percent (24%) report that it takes seven hours or more to complete an admission. Fifty percent (50%) of respondents are confident to complete the necessary paperwork. Overall GPs are dissatisfied with arrangements for transport of patients (mean Likert score 3.5), primarily due to the time delay. GPs believe this places risk on the patient, family and GP. Only thirty-three percent (33%) of respondents feel that the Mental Health Act has improved the patient, GP and family experience of involuntary admission.

    Full Text Available Abstract Background Hypertension prevalence is high in China, while patients’ levels of hypertension awareness, treatment and control are low. General practitioners’ knowledge and training relating to hypertension prevention may be an important related factor. We aimed to investigate general practitioners’ knowledge of hypertension prevention and potential training needs. Methods A questionnaire survey was conducted among all general practitioners at five community health service centers selected by convenience sampling. A total of 160 questionnaires were distributed and 147 were returned (response rate 91.9% The questionnaire included general information; 12 subjective questions on health promotion, education and training needs; and 19 objective questions in 5 domains (epidemiology, diagnosis, treatment, referral and community management measuring knowledge of hypertension prevention and treatment. Results The major difficulties in health education practice for general practitioners were poor patient compliance (77.6% and lack of medical consultation time (49.0%. The average accuracy rate of hypertension prevention knowledge was 49.2%, ranging from 10.5% to 94.7%. The factors associated with accuracy rate were physician’s education level (medical university vs. professional school, β = 13.3, P = 0.003, and type of center (training base vs. community healthcare center, β = 12.3, P  Conclusions The knowledge level of hypertension prevention is low among general practitioners in urban settings. Physicians working in community clinics where they participate in a series of teaching, assessing and evaluating systems for hypertension prevention perform better than those in general healthcare centers who lack specific training. Continuing hypertension education is urgently needed to ensure that physicians in general practice are aware of and adhere to the national hypertension prevention guidelines.

    Full Text Available Abstract Background Over-prescribing of benzodiazepines appears common in many countries, a better understanding of prescribing practices and attitudes may help develop strategies to reduce prescribing. This study aimed to evaluate benzodiazepine prescribing behaviour and attitudes in general practitioners practising in Chiang Mai and Lampoon, Thailand. Methods Questionnaire survey of general practitioners in community hospitals, to estimate: i use of benzodiazepines for anxiety/insomnia, panic disorder, depression, essential hypertension, and uncomplicated low back pain and ii views on the optimal duration of benzodiazepine use. Results Fifty-five of 100 general practitioners returned the completed questionnaires. They reported use of benzodiazepines for anxiety/insomnia (n = 51, 93%, panic disorder (n = 43, 78%, depression (n = 26, 43%, essential hypertension (n = 15, 27 % and uncomplicated low back pain (n = 10, 18%. Twenty-eight general practitioners would prescribe benzodiazepines for non-psychiatric conditions, 17 for use as muscle relaxants. Seventy-five per cent, 62% and 29% of the general practitioners agreed or totally agreed with the use of benzodiazepines for insomnia, anxiety and depression, respectively. Practitioners agreed that prescribing should be less than one week (80%; or from 1 week to 1 month (47%; or 1 to 4 months (16%; or 4 to 6 months (5% or more than 6 months (2%. Twenty-five general practitioners (45% accepted that they used benzodiazepines excessively in the past year. Conclusion A considerable proportion of general practitioners in Chiang Mai and Lampoon, Thailand inappropriately use benzodiazepines for physical illnesses, especially essential hypertension and uncomplicated low back pain. However, almost half of them thought that they overused benzodiazepines. General practitioner's lack of time, knowledge and skills should be taken into account in improving prescribing behaviour and attitudes.

    Rural communities face an impending surgical workforce crisis. The purpose of this study is to describe perceptions of rural Tennessee hospital administrators regarding the importance of surgical services to their hospitals. In collaboration with the Tennessee Hospital Association, we developed and administered a 13-item survey based on a recently published national survey to 80 rural Tennessee hospitals in August 2008. A total of 29 responses were received for an overall 36.3 per cent response rate. Over 44 per cent of rural surgeons were older than 50 years of age, and 27.6 per cent of hospitals reported they would lose at least one surgeon in the next 2 years. The responding hospitals reported losing 10.4 per cent of their surgical workforce in the preceding 2 years. Over 53 per cent were actively recruiting a general surgeon with an average time to recruit a surgeon of 11.8 months. Ninety-seven per cent stated that having a surgical program was very important to their financial viability with the mean and median reported revenue generated by a single general surgeon being $1.8 million and $1.4 million, respectively. Almost 11 per cent of the hospitals stated they would have to close if they lost surgical services. Although rural Tennessee hospitals face similar difficulties to national rural hospitals with regard to retaining and hiring surgeons, slightly more Tennessee hospitals (54 vs 36%) were actively attempting to recruit a general surgeon. The shortage of general surgeons is a threat to the accessibility of comprehensive hospital-based care for rural Tennesseans.

    We use publicly available data obtained with the Advanced Camera for Surveys (ACS) instrument on the Hubble Space Telescope to construct the ACS General Catalog (ACS-GC). The ACS-GC includes over 370,000 astronomical sources (stars + galaxies) derived from the AEGIS, COSMOS, GEMS, and GOODS surveys. We include publicly available redshifts from the DEEP2, COMBO-17, TKRS, PEARS and zCOSMOS surveys to supply redshifts for a considerable fraction ( 52%) of the imaging sample. GALAPAGOS was used to construct photometric (SExtractor) and morphological (GALFIT) catalogs. The morphological analysis assumes a single Sersic model for each object to derive quantitative structural parameters. Galaxy Zoo will measure visual morphologies for 200,000 of these galaxies. The ACS-GC includes color images, GALFIT residual images, a galaxy atlas, and a photometry + morphology + redshift catalog. We use these data to investigate the size-redshift relationship for both early and late-type galaxies out to z 1. The entire data set will be made publicly available through the NASA Extragalactic Database (NED) and LEVEL5.

    Considering general public as potential patients, identifying factors that hinder public participation poses great importance, especially in a research environment where demands for clinical trial participants outpace the supply. Hence, the aim of this study was to evaluate knowledge and perception about clinical research in general public. A total of 400 Seoul residents with no previous experience of clinical trial participation were selected, as representative of population in Seoul in terms of age and sex. To minimize selection bias, every fifth passer-by was invited to interview, and if in a cluster, person on the very right side was asked. To ensure the uniform use of survey, written instructions have been added to the questionnaire. Followed by pilot test in 40 subjects, the survey was administered face-to-face in December 2014. To investigate how perception shapes behavior, we compared perception scores in those who expressed willingness to participate and those who did not. Remarkably higher percentage of responders stated that they have heard of clinical research, and knew someone who participated (both, P perceptions and lack of knowledge will be effective in enhancing public engaged in clinical research.

    2015-01-01

    Full Text Available Background: An association between oral conditions such as periodontal diseases and systemic conditions is noted. As such, periodontal disease is associated with an increased risk of systemic illnesses such as cardiovascular disease, diabetes, adverse pregnancy outcome, atherosclerosis, stroke and hospital acquired pneumonia. The concept of diagnosing and treating a potential patient to minimize the deleterious effects of this chronic infectious and inflammatory condition on systemic conditions represents both an unprecedented challenge and opportunity to our profession. Keeping this in view, the present survey was designed to evaluate the acquaintance, orientation and behavior of general medical practitioners; concerning the effects of periodontal disease on systemic health. Materials and Methods: A typed questionnaire carrying four sets of questions was distributed among general medical practitioners of seven different government and private medical colleges and hospitals. Questionnaire was developed to assess the acquaintance, orientation and behavior of general medical practitioners toward periodontal disease. Results: Most of the respondents have knowledge regarding the signs and symptoms of periodontal disease and its association with cardiovascular disease. However, majority of them do not know about the potential effect of periodontal disease on other organ systems. Conclusion: General medical practitioners have inadequate knowledge regarding periodontal diseases. Hence, oral health related training should be an integral part of the medical curriculum.

    An important consideration in health service delivery is ensuring that services meet consumer needs. Whilst nursing services in primary care have grown internationally, there has been limited exploration of consumer satisfaction with these services. This paper reports a descriptive survey that sought to evaluate consumers' perceptions of New Zealand practice nurses (PNs). One thousand, five hundred and five patients who received nursing services at one of 20 participating New Zealand general practices completed a survey tool between December 2010 and December 2011. The 64-item self- report survey tool contained the 21-item General Practice Nurse Satisfaction (GPNS) scale. Data were analysed using both descriptive and inferential statistics. Internal consistency of the GPNS scale was high (Cronbach's α 0.97). Participants aged over 60 years and those of European descent were significantly less satisfied with the PN (P = 0.001). Controlling for these characteristics, participants who had visited the PN more than four times previously were 1.34 times (adjusted odds ratio 1.34 (95% CI: 1.06-1.70) more satisfied than the comparison group (up to 4 previous visits to PN). In addition to the further validation of the psychometric properties of the GPNS scale in a different setting, the study also revealed a high level of satisfaction with PNs, with increased satisfaction with an increased number of visits. Nevertheless, the lower levels of satisfaction with PNs in the older age group as well as those of European descent, warrants further examination. The study also highlights the need for PNs and consumers to discuss consumer's expectations of services and create a shared understanding of treatment goals.

    Full Text Available Cross-sectional studies have associated short telomere length with smoking, body weight, physical activity, and possibly alcohol intake; however, whether these associations are due to confounding is unknown. We tested these hypotheses in 4,576 individuals from the general population cross-sectionally, and with repeat measurement of relative telomere length 10 years apart. We also tested whether change in telomere length is associated with mortality and morbidity in the general population. Relative telomere length was measured with quantitative polymerase chain reaction. Cross-sectionally at the first examination, short telomere length was associated with increased age (P for trend across quartiles = 3 × 10(-77, current smoking (P = 8 × 10(-3, increased body mass index (P = 7 × 10(-14, physical inactivity (P = 4 × 10(-17, but not with increased alcohol intake (P = 0.10. At the second examination 10 years later, 56% of participants had lost and 44% gained telomere length with a mean loss of 193 basepairs. Change in leukocyte telomere length during 10 years was associated inversely with baseline telomere length (P<1 × 10(-300 and age at baseline (P = 1 × 10(-27, but not with baseline or 10-year inter-observational tobacco consumption, body weight, physical activity, or alcohol intake. Prospectively during a further 10 years follow-up after the second examination, quartiles of telomere length change did not associate with risk of all-cause mortality, cancer, chronic obstructive pulmonary disease, diabetes mellitus, ischemic cerebrovascular disease, or ischemic heart disease. In conclusion, smoking, increased body weight, and physical inactivity were associated with short telomere length cross-sectionally, but not with telomere length change during 10 years observation, and alcohol intake was associated with neither. Also, change in telomere length did not associate prospectively with mortality or morbidity in the general population.

    Case reports and hospital-based case-control studies suggest that cannabis use may increase the risk of stroke. We examined the risk of non-fatal stroke or transient ischemic attack (TIA) among cannabis users in the general community. A general population survey of Australians aged 20-24 years (n=2,383), 40-44 years (n=2,525) and 60-64 years (n=2,547) was used to determine the odds of lifetime stroke or TIA among participants who had smoked cannabis in the past year while adjusting for other stroke risk factors. There were 153 stroke/TIA cases (2.1%). After adjusting for age cohort, past year cannabis users (n=1,043) had 3.3 times the rate of stroke/TIA (95% CI 1.8-6.3, pcannabis weekly or more often (IRR 4.7, 95% CI 2.1-10.7) with no elevation among participants who used cannabis less often. Heavy cannabis users in the general community have a higher rate of non-fatal stroke or transient ischemic attack than non-cannabis users. © 2015 Public Health Association of Australia.

    We report the results of a deep near-infrared survey of the vicinity of supernova remnant N49 in the Large Magellanic Cloud (LMC), which contains the soft gamma-ray repeater (SGR) 0526-66. Two of the four confirmed SGRs are potentially associated with compact stellar clusters. We thus searched for a similar association of SGR0526-66, and find the unexplored young stellar cluster SL 463 at a projected distance of approx. 30 pc from the SGR. This constitutes the third cluster-SGR link, and lends support to scenarios in which SGR progenitors originate in young, embedded clusters. If real, the cluster-SGR association constrains the age and thus the initial mass of these stars. In addition, our high-resolution images of the super- nova remnant N49 reveal an area of excess K-band flux in the southeastern part of the SNR. This feature coincides with the maximum flux area at 8.28 microns as detected by the Midcourse Space Experiment (MSX satellite), which we identify with IRAS 052594607.

  11. Short repeats in the spa gene of Staphylococcus aureus are prone to nonsense mutations: stop codons can be found in strains isolated from patients with generalized infection.

    Fifteen sequences with stop codons have been obtained in the course of standard methicillin-resistant Staphylococcus aureus (MRSA) spa typing. In nine of those sequences, stop codons occurred due to nonsense G-T and A-T transversions. G-T transversions would appear to be frequent in the spa gene, mostly due to symmetric mutational AT-pressure in the whole S. aureus genome and due to replication-associated mutational pressure characteristic of lagging strands of the "chromosome". A-T transversions would appear to be frequent in the spa gene mostly due to transcription-associated mutational pressure. Relative to other S. aureus genes, short repeats in spa are enriched by nonsense sites for G-T and A-T transversions; the probability of being nonsense for A-T transversion is high in that part of spa coding region. 13 out of 15 (87%) of the sequences with stop codons were obtained from strains isolated from patients with generalized S. aureus infection. Truncation of spa at its C-terminus is predicted to result in a protein that possesses functional IgG binding domains unable to be linked to the cell wall. This is discussed in light of the known fact that extracellular spa is a strong virulence factor involved in immune evasion. Copyright © 2013 Institut Pasteur. Published by Elsevier Masson SAS.

    Exposure to repetitive seizures is known to promote convulsions which depend on specific patterns of network activity. We aimed at evaluating the changes in seizure phenotype and neuronal network activation caused by a modified 6-Hz corneal stimulation model of psychomotor seizures. Mice received up to 4 sessions of 6-Hz corneal stimulation with fixed current amplitude of 32 mA and inter-stimulation interval of 72 h. Video-electroencephalography showed that evoked seizures were characterized by a motor component and a non-motor component. Seizures always appeared in frontal cortex, but only at the fourth stimulation they involved the hippocampus, suggesting the establishment of an epileptogenic process. Duration of seizure non-motor component progressively decreased after the second session, whereas convulsive seizures remained unchanged. In addition, a more severe seizure phenotype, consisting of tonic-clonic generalized convulsions, was predominant after the second session. Immunohistochemistry and double immunofluorescence experiments revealed a significant increase in neuronal activity occurring in the lateral amygdala after the fourth session, most likely due to activity of principal cells. These findings indicate a predominant role of amygdala in promoting progressively more severe convulsions as well as the late recruitment of the hippocampus in the seizure spread. We propose that the repeated 6-Hz corneal stimulation model may be used to investigate some mechanisms of epileptogenesis and to test putative antiepileptogenic drugs.

    The aim of this study was to evaluate the awareness and perception of general educated Indian individuals about Doctor of Pharmacy course. A cross-sectional structured Pharm.D questionnaire survey was conducted at educational institutions of India mainly through e-mails. Pharm.D questionnaire survey was conducted over a period of six months. The questionnaire was classified into four major categories, including course-related questions, roles-related questions, critical comparative questions, and opinion-based questions. The responses were collected and analyzed to assess the opinions and attitudes of the study population regarding the course Pharm.D. Out of 2819 responses, 66.01% agreed that Indian syllabus, teaching procedure, and hospital training in institutions are enough to prepare an ideally graduated Pharm.D. Respondents of about 70.59% agreed that Pharm.Ds should take care of complete responsibility of drug therapy rather than physicians prescribing the medications and Pharm.Ds fixing the dose. The statement "Pharm.Ds play a vital role in improving medication adherence through patient counseling" was accepted by 47.80%, whereas 41.40% did not accept it as they felt that the Pharm.D's role in this regard is not more than the physician's role, and 10.80% suggested that other healthcare professionals would play a better role. Among all the respondents, 73.64% of the study population was found to be ready for giving equal credit and respect to Pharm.Ds as physicians. Our survey emphasizes on the opinion of educated people of having Pharm.Ds in both government and private hospitals to take care of complete therapy and for improving medication adherence.

    General physicians (GP) play a key role in providing appropriate care for people with dementia. It is important to understand their workload and opinions regarding areas for improvement. A group of 1,109 GPs working in Mecklenburg-Western Pomerania, Gemany (1.633 million inhabitants), were identified, contacted and asked to participate in a written survey. The survey addressed five main topics: (a) the GP, (b) the GP's practice, (c) the treatment of dementia, (d) personal views, attitudes and specific competences regarding dementia and (e) the GP's recommendations for improving dementia-related health care. The survey response rate was 31%. In total, the responding GPs estimated that they provided care to 12,587 patients with dementia every quarter year. The GPs also reported their opinions about screening instruments, treatment and recommendations for better care of dementia patients. Only 10% of them do not use screening instruments, one third felt competent in their care for patients with dementia and 54% opt for transfer of patients to a specialist for further neuropsychological testing. Four conclusions from this study are the following: (a) dementia care is a relevant and prevalent topic for GPs, (b) systematic screening instruments are widely used, but treatment is guided, mostly by clinical experience, (c) attitudes towards caring for people with dementia are positive, and (d) GPs recommend spending a lot more time with patients and caregivers and provision of better support in social participation. A majority of GPs recommend abolishing "Budgetierung", a healthcare budgeting system in the statutory health insurance programmes.

    Full Text Available This study tested the dimensionality of the Maslach Burnout Inventory – General Survey (MBI-GS on a sample of 1190 Romanian healthcare professionals from three county hospitals. Data provided evidence to support the hypothesised three-factor model after removing one item from the cynicism scale: χ2(86 = 432.29, CFI = .94, GFI = .95, NFI = .93, and RMSEA = .05. Results of multigroup analysis confirmed the invariance of the 15 items model across professional role, gender, age, and organisational tenure. Structural equation modeling results proved specific relations between occupational factors and burnout dimensions. Our results have practical implications for future research on burnout using the MBI-GS among samples of healthcare professionals.

    Full Text Available In this paper we use the Aging and Social Support Survey (GSS16 and the theoretical conception of a ‘housing career’ to identify the correlates of housing tenure (rent vs. own among Canadians age 45 and over. We draw on primarily US literature to isolate three general explanatory clusters (social support, health, and economic characteristics. Based on analyses using logistic regression, the results indicate that the majority of variation in housing tenure exists due to standard demographic and household characteristics. In fact, of the three focal explanatory clusters, only social support characteristics significantly enhance model fit beyond the baseline model, suggesting that the housing tenure of older Canadians hinges heavily on fairly standard characteristics.

    General frameworks for distributed computing are slowly evolving out of Grid, Peer Architecture, and Web Services. The following results from a summer long survey into distributing computing practices have revealed three things. One, that Legion and Cactus-G have achieved the most in terms of providing an all-purpose application environment. Two, that extending a local programming environment to operate in a highly distributed fashion can be facilitated with toolkits like Globus. Three, that building a new system from the ground up could be realized, in part, by using some of the following components; an Object Oriented Database, Tapestry, JXTA, BOINC, Globus, component architecture technology, XML and related libraries, Condor-G, Proteus, and ParMETIS.

    The purpose of this study was to validate Japanese research version of Maslach Burnout Inventory-General Survey (MBI-GS), a newly developed measure intended for persons of every occupation. The Japanese MBI-GS was administered to a sample of hospital workers. Exploratory factor analysis found three factors, as in original MBI-GS. Confirmatory factor analysis largely supported MBI-GS structure of three subscales, but the correlation between two subscales was unexpectedly high. To examine its construct validity, the subscale scores were then examined in relation to selected work characteristics. Conservation of resources theory was successful in its predictions of different patterns of effects among the correlates and three burnout subscales. The successful predictions suggested that meaning of each subscale was quite distinct. In all, our examination showed that Japanese MBI-GS assessed the same three dimensions as the original measure for human service workers.

    Extreme heat is associated with an increased mortality and morbidity. National heat plans have been implemented to minimize the effect of extreme heat. The population's awareness and knowledge of national heat plans and extreme heat is essential to improve the community's behavior and adaptation. A general population survey was conducted in Lisbon and in Madrid to assess this knowledge. We used a questionnaire to interview passers-by. Results were compared between Lisbon and Madrid and between locals and foreigners, using Pearson Chi-square tests and Fisher's exact test. We conducted 260 interviews in six locations of different socio-economic backgrounds in each city. The most frequently mentioned extreme heat-related risk groups were the elderly (79.2%), children (49.6%) and babies (21.5%). The most frequently reported protective measures were increased fluid intake (73.1%) and avoiding exposure to the sun (50.8%). Knowledge about the heat plan was higher in Lisbon (37.2%) than in Madrid (25.2%) (p-value = 0.03). Foreigners had less knowledge of risk groups compared to locals. Heat plans were not widely known in Madrid and Lisbon. Nonetheless, knowledge of practical concepts to face extreme heat, such as certain risk groups and protective measures, was found. Our results were similar to comparable surveys where specific respondents' groups were identified as less knowledgeable. This highlighted the importance of addressing these groups when communicating public health messages on heat. Foreigners should be specifically targeted to increase their awareness.

    This study aimed to assess the incidence of unintentional injuries presented in general practice, and to identify children at risk from experiencing an unintentional injury. We used the data of all 0–17-year-old children from a representative survey in 96 Dutch general practices in 2001. We computed incidence rates and multilevel multivariate regression analysis in different age strata and identified patient and family characteristics associated with an elevated injury risk. Nine thousand four hundred and eighty-four new injury episodes were identified from 105 353 new health problems presented in general practice, giving an overall incidence rate of 115 per 1000 person years (95% confidence interval [CI] = 113 to 118). Sex and residence in rural areas are strong predictors of injury in all age strata. Also, in children aged 0–4 years, a higher number of siblings is associated with elevated injury risk (≥3 siblings odds ratio [OR] = 1.57, 95% CI = 1.19 to 2.08) and in the 12–17-year-olds, ethnic background and socioeconomic class are associated with experiencing an injury (non-western children OR = 0.67, 95% CI = 0.54 to 0.81; low socioeconomic class OR = 1.39, 95% CI = 1.22 to 1.58). Unintentional injury is a significant health problem in children in general practice, accounting for 9% of all new health problems in children. In all age groups, boys in rural areas are especially at risk to experience an injury. PMID:16105373

    Full Text Available Abstract Background Obesity is a main threat to public health in the Western world and is associated with diseases such as diabetes mellitus and coronary heart diseases. Up to now a minority of research studied the relation between obesity and the use of primary health care. In the Netherlands the general practitioner (GP is the main primary health care provider. The objective of this article is to evaluate GP consultation and prescription of drugs in moderate and severely overweight (obese persons in the Netherlands. Methods Data were used from a representative survey of morbidity in Dutch general practice in 2001. Our study sample consisted of 8,944 adult respondents (18+ years who participated in an extensive health interview. Interview data were linked to morbidity and prescription registration data from 95 general practices where respondents were listed. Body mass index (BMI was calculated using self-reported height and weight. Analyses were controlled for clustering within practices as well as for socio-demographic and life style characteristics. Results Obesity (BMI ≥ 30 kg/m2 was observed in 8.9% of men and 12.4% of women; for moderate overweight (BMI 25- Conclusion Obesity increases the workload of Dutch general practitioners and the use of prescribed medication. The current increase in the prevalence of obesity will further increase the use of health care and related costs. Since a large majority of Dutch persons visit their GP over the course of one year, GPs' potential role in effective prevention strategies cannot be denied.

    Modern cancer care is provided in highly specialized structures as certificated centres and comprehensive cancer center, as well as specialized practices. In contrast, the position of the general practitioner (GP) is less well characterised and there is a lack of information about his importance in the care for cancer patients. The aim of our survey was to assess the role of GPs in German cancer care from patients' perspective. In several steps we developed a standardized anonymous questionnaire in cooperation with the German Association of General Practitioners and the Federal Association of German Self-Help Groups. This questionnaire was used in a print and an online version and distributed by the self-help organizations to their members. Seven hundred and forty participants took part in the survey, 66.5% women and 30.1% men. 71% had visited the GP during cancer therapy and 34.5% discussed decisions concerning diagnostics and therapy with him. The most relevant reasons to visit the GP during cancer therapy were to get a blood test (63.3%), comorbidities (42.7%) and complaints and side effects (38.3%). For the latter, most often a detailed discussion ensued (57%), fooled by a prescription (37.7%). In 63.4% the GP offered support when patients had some questions or worries concerning their cancer. Yet, 17% of the patients reported that the GP did not try to help. 85.5% of the participants thought that it is important that their GP is informed about the therapy on a regular basis. For 77.0%, a simultaneous care provided by the GP is important or very important. Our survey points to the importance of the GP during cancer therapy from the patient's point of view. Patients want their GP to take an active part in the cancer therapy. Furthermore, early integration of the GP may also enhance early integration of palliative care and also help family members and caregivers. A strategy to integrate GPs is the establishment of shared care models, in which GPs are supported by

    Full Text Available This article analyzes the data on the composition of forests, species of animals and birds in the Valdai district of Novgorod province, available in the notes to the General Economic surveying conducted by Catherine II. The study database containing information about the natural environment of the Valdai district in the second half of the XVIII century was created, the state of forests, composition of species and the number of mammals and birds was assessed as well. The author concludes that the surveyors inscribed the notes about specific trees, animals and birds on the basis of their relevance to population and greater prevalence of a particular area in the economic records. Over the past centuries on the territory of the Valdai there was a steady tendency of spreading spruce-deciduous and pine forests with a large number of birches, replacing the primary spruce forests as a result of the economic development of the territory. As referred to Economic notes specific composition of trees, mammals and birds has in general survived to our time. At the same time, a sharp reduction in the number of hunting birds on the territory of the Valdai as well as the spreading of animals previously unknown in this territory, including specially imported for breeding or expanding an area of their habitat is observed.

    Full Text Available Abstract Background Five percent of the Swiss population attribute symptoms to electromagnetic fields (EMF. General practitioners (GPs might play a key role in recognising an emerging health risk, since they are the first to observe and follow up persons who attribute symptoms to EMF. It is unclear to what extent EMFs have become an issue in general practice and which experiences GPs report from the consultations. Methods We conducted telephone interviews in a random sample of GPs in Switzerland in order to assess the frequency of consultations in primary care due to EMF and the GPs' experience with these patients. Results 342 general practitioners were interviewed, corresponding to a response rate of 28.2%. 69% of the GPs reported at least one consultation due to EMF, but GPs with a certificate in complementary medicine were much more likely to report EMF consultations. The median of EMF consultation numbers within one year was three. An overview of the most recent EMF-related consultation per GP yielded sleep disorders, headaches and fatigue as the most often reported symptoms and mobile phone base stations, power lines and the own use of mobile phones as the main EMF sources suspected to be associated to symptoms. GPs judged the association between EMF and the symptoms to be plausible in 54% of the cases. There was no combination of symptoms and EMF sources that was remarkably and consistently judged to be a plausible cause of the symptoms. Conclusion In our survey, GPs often judged the association between the health problems and the suspected exposure to be plausible. This plausibility assessment seems to be based on grounds of preventive positions in a situation of scientific uncertainty. More research effort is needed to obtain more insight on a potential association between long term EMF exposure and unspecific symptoms.

To investigate the attitudes of Chinese patients and the general public on providing consent for storage and use of leftover biosamples. Cross-sectional surveys were conducted among randomly selected patients admitted to a Shanghai city hospital (n = 648) and members of the general public (n = 492) from May 2010 to July 2010. Face-to-face interviews collected respondents-report of their willingness to donate residual biosample, trust in medical institutions, motivation for donation, concerns of donated sample use, expectations for research results return, and so on. The response rate was 83.0%. Of the respondents, 89.1% stated that they completely understood or understood most of questions. Willingness to donate residual sample was stated by 64.7%, of which 16.7% desired the option to withdraw their donations anytime afterwards. Only 42.3% of respondents stated they "trust" or "strongly trust" medical institutions, the attitude of trusting or strongly trusting medical institutions were significantly associated with willingness to donate in the general public group.(p<0.05) The overall assent rate for future research without specific consents was also low (12.1%). Hepatitis B virus carriers were significantly less willing than non-carriers to donate biosamples (32.1% vs. 64.7%, p<0.001). Low levels of public trust in medical institutions become serious obstacle for biosample donation and biobanking in China. Efforts to increase public understanding of human medical research and biosample usage and trust in the ethical purposes of biobanking are urgently needed. These efforts will be greatly advanced by the impending legislation on biobanking procedures and intent, and our results may help guide the structure of such law.

    Purpose The purpose of this study is to identify risk factors of physical violence in Chinese township hospitals. Methods A cross-sectional survey was used in a sample of 442 general practitioners and 398 general nurses from 90 township hospitals located in Heilongjiang province, China (response rate = 84.8%). Results A total of 106 of the 840 (12.6%) respondents reported being physically attacked in their workplace in the previous 12 months. Most perpetrators were the patients’ relatives (62.3%), followed by the patient (22.6%); 73.6% of perpetrators were aged between 20 and 40 years. Of the physical violence incidents, about 56.6% (n = 60) resulted in a physical injury, and 45.4% of respondents took two or three days of sick leave. Reporting workplace violence in hospitals to superiors or authorities was low (9.4%). Most respondents (62.8%) did not receive training on how to avoid workplace violence. Logistic regression analyses indicated that general nurses, aged 35 years or younger, and with a higher-level professional title were more likely to experience physical violence. Healthcare workers with direct physical contact (washing, turning, lifting) with patients had a higher risk of physical violence compared to other health care workers. Procedures for reporting workplace violence were a protective factor for physical violence; when in place, reporting after psychological violence (verbal abuse, bullying/mobbing, harassment, and threats) was more protective than waiting until an instance of physical violence (beating, kicking, slapping, stabbing, etc.). Conclusions Physical violence in Chinese township hospitals is an occupational hazard of rural public health concern. Policies, procedures, and intervention strategies should be undertaken to manage this issue. PMID:26571388

    Full Text Available Abstract Background Poorly controlled asthma can lead to maternal and fetal complications. Despite the known risks of poorly controlled asthma during pregnancy and the need for stepping up therapy when appropriate, there are concerns that management is suboptimal in primary care. Our objective was to investigate the management of asthma during pregnancy by general practitioners providing shared maternity care. Methods A pre-piloted, anonymous mail survey was sent to all general practitioners (n = 842 involved in shared maternity care at six maternity hospitals in Victoria, Australia. Respondents were asked about their perceived safety of individual asthma medications during pregnancy. Approach to asthma management during pregnancy was further explored using scenarios of pregnant women with stable and deteriorating asthma and poor medication adherence. Results Inhaled corticosteroids (ICS were perceived to be the safest and were the preferred preventive medication in first trimester (74.1%, whilst leukotriene receptor antagonists were the least preferred (2.9%. A quarter (25.8% of respondents would stop or decrease patients' ICS doses during pregnancy, even when their asthma was well controlled by current therapy. In addition, 12.1% of respondents were not sure how to manage deteriorating asthma during pregnancy and opted to refer to another health professional. Almost half the respondents (48.9% reported encountering medication nonadherence during pregnancy. Conclusion A lack of confidence and/or knowledge among general practitioners in managing deteriorating asthma in pregnancy was observed despite a good understanding of the safety of asthma medications during pregnancy, compliance with evidence-based guidelines in the selection of preventive medications, and self reported good asthma knowledge.

    Despite a clear impact on the Canadian economy, little is known about the subsequent health impacts of the 2008 global financial crisis (GFC) in this country. This study fills this gap in knowledge by conducting a repeated cross-sectional analysis of the Canadian Community Health Survey (CCHS). Data from 7 cycles (2007-2013) of the CCHS were combined to form a large data set representative of the Canadian working-age population (15-64 years) residing in 1 of 10 provinces. A logistic regression model was used to determine whether exposure to various periods of the GFC resulted in increased odds of reporting poor mental health. Exposure was categorised into 4 periods based on political and economic indicators, as follows: precrisis period (baseline), initial crisis period, stimulus period and austerity period. Other outcomes investigated included: anxiety disorders (AD), mood disorders (MD), poor physical health and health-related behaviours (heavy alcohol drinking (HAD) and decreased fruit/vegetable consumption (FVC)). A significant increased odds of reporting poor mental health was observed during the austerity period compared with the precrisis period (OR=1.26 (1.16 to 1.32)); findings remain significant when adjusted for sex, marital status and education. Exposure to the austerity period was also significantly associated with increased odds of reporting AD, MD, HAD and decreased odds of FVC. No significant associations were observed for the poor self-perceived physical health variable. Statistically significant associations were observed between several negative health outcomes and the austerity period when compared with the precrisis period. Austerity has been linked to worsening health in other studies and represents an example of how the policy response can have greater detrimental impact on health than the financial crisis itself.

    This study aimed to improve the quality of documentation on antibiotic therapy in the computerized medical records of inpatients. A prospective, uncontrolled, interrupted time series (ITS) study was conducted by repeated point prevalence survey (PPS) to audit the quality of documentation on antibiotic therapy in the medical records before and after a combined intervention strategy (implementation of guidelines, distribution of educational materials, educational outreach visits, group educational interactive sessions) from the antimicrobial stewardship team (AST) in the academic teaching hospital (CHU) of Liège, Belgium. The primary outcome measure was the documentation rate on three quality indicators in the computerized medical records: (1) indication for treatment, (2) antibiotics prescribed, and (3) duration or review date. Segmented regression analysis was used to analyze the ITS. The medical records of 2306 patients receiving antibiotics for an infection (1177 in the pre-intervention period and 1129 in the post-intervention period) were analyzed. A significant increase in mean percentages in the post-intervention period was observed as compared with the pre-intervention period for the three quality indicators (indication documented 83.4 ± 10.4 % vs. 90.3 ± 6.6 %, p = 0.0013; antibiotics documented 87.9 ± 9.0 % vs. 95.6 ± 5.1 %, p documented 31.9 ± 15.4 % vs. 67.7 ± 15.2 %, p documentation rate in the computerized medical records for the three quality indicators.

    Minimally invasive surgery fellowships offer experience in robotic surgery, the nature of which is poorly defined. The objective of this survey was to determine the current status and opportunities for robotic surgery training available to fellows training in the United States and Canada. Sixty-five minimally invasive surgery fellows, attending a fundamentals of fellowship conference, were asked to complete a questionnaire regarding their demographics and experiences with robotic surgery and training. Fifty-one of the surveyed fellows completed the questionnaire (83 % response). Seventy-two percent of respondents had staff surgeons trained in performing robotic procedures, with 55 % of respondents having general surgery procedures performed robotically at their institution. Just over half (53 %) had access to a simulation facility for robotic training. Thirty-three percent offered mechanisms for certification and 11 % offered fellowships in robotic surgery. One-third of the minimally invasive surgery fellows felt they had been trained in robotic surgery and would consider making it part of their practice after fellowship. However, most (80 %) had no plans to pursue robotic surgery fellowships. Although a large group (63 %) felt optimistic about the future of robotic surgery, most respondents (72.5 %) felt their current experience with robotic surgery training was poor or below average. There is wide variation in exposure to and training in robotic surgery in minimally invasive surgery fellowship programs in the United States and Canada. Although a third of trainees felt adequately trained for performing robotic procedures, most fellows felt that their current experience with training was not adequate.

    The level of human immunodeficiency virus (HIV), tuberculosis (TB) as well as the co-infection TB/HIV in South Africa is among the highest in the world. TB is curable while HIV is not, yet the combination of both is a growing feature in the world. This study examined TB and HIV affecting people living in South Africa. Analyses have been undertaken based on data from the General Household Survey of South Africa in 2006. The study focused on respondents aged 15-49 years, corresponding to a total of 55,384 people composed of 25,859 males and 29,525 females. Among this population, 5935 people suffered from illness/injury, including 2469 (41.6%) males and 3466 (58.4%) females. Weighted multivariate logistic regression is performed on TB and/or HIV in association with the province, background characteristics of the target population, and selected socioeconomic and demographic variables included in the survey. In this study we focus on variables of health status and whether subjects suffered from TB and/or HIV. Findings of this investigation show that TB is the second most common cause of illness in the provinces of KwaZulu-Natal (KN) (9.1%), North West (5.4%) and Limpopo (4.2%). People who are married have a 50% lower risk compared to those currently not married to suffer from TB and/or HIV. Those with living spouses have a 5% lower risk to suffer from TB and/or HIV than those whose partners are not alive. This study concluded that rapid action is needed to curb the spread of TB and/or HIV to produce a healthy population. Therefore, follow-up care and special preventative measures are urgently needed in provinces with higher reported rates of TB and/or HIV such as KN.

    Studies in Canada, the USA and Australia suggested low confidence among general practitioners (GPs) in diagnosing and managing shoulder pain, with frequent use of investigations. There are no comparable studies in the UK; our objective was to describe the diagnosis and management of shoulder pain by GPs in the UK. A national survey of a random sample of 5000 UK GPs collected data on shoulder pain diagnosis and management using two clinical vignettes that described primary care presentations with rotator cuff tendinopathy (RCT) and adhesive capsulitis (AdhC). Seven hundred and fourteen (14.7%) responses were received. 56% and 83% of GPs were confident in their diagnosis of RCT and AdhC, respectively, and a wide range of investigations and management options were reported. For the RCT presentation, plain radiographs of the shoulder were most common (60%), followed by blood tests (42%) and ultrasound scans (USS) (38%). 19% of those who recommended a radiograph and 76% of those who recommended a USS did so 'to confirm the diagnosis'. For the AdhC presentation, the most common investigations were blood tests (60%), plain shoulder radiographs (58%) and USS (31%). More than two-thirds of those recommending a USS did so 'to confirm the diagnosis'. The most commonly recommended treatment for both presentations was physiotherapy (RCT 77%, AdhC 71%) followed by non-steroidal anti-inflammatory drugs (RCT 58%, AdhC 74%). 17% opted to refer the RCT to secondary care (most often musculoskeletal interface service), compared with 31% for the AdhC. This survey of GPs in the UK highlights reliance on radiographs and blood tests in the management of common shoulder pain presentations. GPs report referring more than 7 out of 10 patients with RCT and AdhC to physiotherapists. These findings need to be viewed in the context of low response to the survey and, therefore, potential non-response bias. © Article author(s) (or their employer(s) unless otherwise stated in the text of the

    Full Text Available Abstract Background Parents of children with food allergy, primary care physicians, and members of the general public play a critical role in the health and well-being of food-allergic children, though little is known about their knowledge and perceptions of food allergy. The purpose of this paper is to detail the development of the Chicago Food Allergy Research Surveys to assess food allergy knowledge, attitudes, and beliefs among these three populations. Methods From 2006–2008, parents of food-allergic children, pediatricians, family physicians, and adult members of the general public were recruited to assist in survey development. Preliminary analysis included literature review, creation of initial content domains, expert panel review, and focus groups. Survey validation included creation of initial survey items, expert panel ratings, cognitive interviews, reliability testing, item reduction, and final validation. National administration of the surveys is ongoing. Results Nine experts were assembled to oversee survey development. Six focus groups were held: 2/survey population, 4–9 participants/group; transcripts were reviewed via constant comparative methods to identify emerging themes and inform item creation. At least 220 participants per population were recruited to assess the relevance, reliability, and utility of each survey item as follows: cognitive interviews, 10 participants; reliability testing ≥ 10; item reduction ≥ 50; and final validation, 150 respondents. Conclusion The Chicago Food Allergy Research surveys offer validated tools to assess food allergy knowledge and perceptions among three distinct populations: a 42 item parent tool, a 50 item physician tool, and a 35 item general public tool. No such tools were previously available.

    2011-01-01

    Internet-scale quantum repeater networks will be heterogeneous in physical technology, repeater functionality, and management. The classical control necessary to use the network will therefore face similar issues as Internet data transmission. Many scalability and management problems that arose during the development of the Internet might have been solved in a more uniform fashion, improving flexibility and reducing redundant engineering effort. Quantum repeater network development is currently at the stage where we risk similar duplication when separate systems are combined. We propose a unifying framework that can be used with all existing repeater designs. We introduce the notion of a Quantum Recursive Network Architecture, developed from the emerging classical concept of 'recursive networks', extending recursive mechanisms from a focus on data forwarding to a more general distributed computing request framework. Recursion abstracts independent transit networks as single relay nodes, unifies software layer...

    In recent years the emergence of multidrug resistant Klebsiella pneumoniae strains has been an increasingly common event. This opportunistic species is one of the five main bacterial pathogens that cause hospital infections worldwide and multidrug resistance has been associated with the presence of high molecular weight plasmids. Plasmids are generally acquired through horizontal transfer and therefore is possible that systems that prevent the entry of foreign genetic material are inactive or absent. One of these systems is CRISPR/Cas. However, little is known regarding the clustered regularly interspaced short palindromic repeats and their associated Cas proteins (CRISPR/Cas) system in K. pneumoniae. The adaptive immune system CRISPR/Cas has been shown to limit the entry of foreign genetic elements into bacterial organisms and in some bacteria it has been shown to be involved in regulation of virulence genes. Thus in this work we used bioinformatics tools to determine the presence or absence of CRISPR/Cas systems in available K. pneumoniae genomes. The complete CRISPR/Cas system was identified in two out of the eight complete K. pneumoniae genomes sequences and in four out of the 44 available draft genomes sequences. The cas genes in these strains comprises eight cas genes similar to those found in Escherichia coli, suggesting they belong to the type I-E group, although their arrangement is slightly different. As for the CRISPR sequences, the average lengths of the direct repeats and spacers were 29 and 33 bp, respectively. BLAST searches demonstrated that 38 of the 116 spacer sequences (33%) are significantly similar to either plasmid, phage or genome sequences, while the remaining 78 sequences (67%) showed no significant similarity to other sequences. The region where the CRISPR/Cas systems were located is the same in all the Klebsiella genomes containing it, it has a syntenic architecture, and is located among genes encoding for proteins likely involved in

    Objective The aims of this study were to estimate the prevalence of mental-physical comorbidity and health-threatening risk factors in subjects with mental disorders, and the risks of mental disorders in those with physical diseases for the last 12 months in the general Korean population. Methods Korean Epidemiologic Catchment Area study replication (KECA-R) was conducted for 6,510 adults between August 2006 and April 2007. The Korean version of Composite International Diagnostic Interview 2.1 (K-CIDI) was used in the survey. Prevalence of mental and physical disorders, and risk factors for physical health were calculated, and their associations were evaluated with adjustment for age and sex. Results Subjects with any mental disorder showed significantly higher prevalence of chronic physical conditions (adjusted odds ratio, AOR=1.5 to 2.8, psmoking, heavy drinking, overweight, and hypertension (AOR=1.5 to 4.0, p<0.001). Of those with chronic physical conditions, 21.6% had one or more comorbid mental disorder compared with 10.5% of the subjects without chronic physical disorders (AOR=2.6, p<0.001). Contrary to expectations, depressive disorders did not show significant association with hypertension and prevalence of obesity was not influenced by presence of mental disorders. Further studies should assess these findings. Conclusion This is the first identification of significant mental-physical comorbidity in the general Korean population. Clinicians and health care officials should keep in mind of its potential adverse effects on treatment outcome and aggravated disease-related socioeconomic burden.

    Background Care for overweight children in general practice involves collaboration with parents. Acknowledging the parents’ frames of references is a prerequisite for successful management. We therefore aimed to analyse parental beliefs about the presumed causes and consequences of overweight in children and expectations towards the GP. Moreover, we aimed at comparing the beliefs and expectations of parents of non-overweight children (NOWC) and parents of overweight children (OWC). Methods A cross-sectional survey. Data were obtained from a questionnaire exploring parents’ beliefs and expectations regarding overweight in children. The questionnaires were completed by parents following their child’s participation in the five-year preventive child health examination (PCHE). Parental agreement upon statements concerning beliefs and expectations regarding overweight in children was measured on a Likert scale. Differences in levels of agreement between parents of non-overweight children and parents of overweight children were analysed using Chi-squared test and Fisher’s exact test. Results Parents of 879 children completed and returned questionnaires. Around three fourths of the parents agreed that overweight was a health problem. A majority of parents (93%) agreed that the GP should call attention to overweight in children and offer counselling on diet and exercise. Almost half of the parents expected a follow-up programme. Parents of overweight children seemed to agree less upon some of the proposed causes of overweight, e.g. inappropriate diet and lack of exercise. These parents also had stronger beliefs about overweight disappearing by itself as the child grows up. Conclusions According to parental beliefs and expectations, general practice should have an important role to play in the management of child overweight. Moreover, our findings suggest that GPs should be aware of the particular beliefs that parents of overweight children may have regarding causes

    The removal of the Marmot Dam on the Sandy River, Oregon in October 2007 released an estimated 430,000 m3 of sand and gravel downstream. Field surveys by Major and others (Major and others, USGS Professional Paper 1792) following the dam removal documented deposition of nearly half of the eroded sediment (215,000 m3) in the first 2 km downstream of the dam within a year of breaching. However, the fate of more than 200,000 m3 of chiefly sand transported farther downstream is uncertain. In the current study, five sequential LiDAR data sets from 2006 to 2011 were used to quantify sediment storage and erosion in the 40 km from the former dam site to the confluence with the Columbia River to track the downstream movement of the sediment released from the reservoir. We hypothesized that a pulse of sediment from the dam removal would be distinguished by a successive downstream growth of sediment bars through time. The LiDAR imagery includes two data sets acquired before the dam removal and three afterward. Geomorphic Change Detection software (GCD) (gcd.joewheaton.org) was used to quantify the locations and volume of sediment erosion and deposition through the successive years of LiDAR imagery. GCD allows for error assessment of each LiDAR-derived digital elevation map (DEM) and propagates the combined errors when differencing two repeat surveys. This process allows creation of DEM of Difference (DoD) maps with associated uncertainty estimates. Preliminary results of the LiDAR analysis agree with the previous field estimates of deposition within the first 2 km from the former dam. Following the initial phase of deposition immediately downstream of the dam breach, the subsequent surveys (2008-2011) show an erosional front beginning to migrate downstream through the newly deposited sediment. Many of the sediment bars still remained in 2011, but were reduced in size. After calibrating the model in the 2-km reach below the dam, we analyzed the additional 38 km of channel

    A walk-through industrial-hygiene survey was conducted at the General Motors Corporation Fisher Guide manufacturing facility located in Monroe, Louisiana. The investigation centered on possible exposure to acrylates or methacrylates during the manufacture of adhesive-sealed, flame-sealed, or composite headlamps. Methacrylate-based adhesives and acrylated coatings have been used at the facility since 1981. Both the adhesives and coatings were cured by ultraviolet radiation. Ninety-four employees had potential contact with acrylates or methacrylates during the application of adhesives and coatings. Adhesives were used for sealing the lens/reflector area and the bulb location of the terminal area. Base coats were applied to the composite headlamps to provide an adhering surface for the aluminized coating. Top coats were applied as a protective coating for the aluminum coating. Two cases of chemical dermatitis have been reported at the facility since 1981 due to skin contact with acrylates/methacrylates. When an automated system was used to apply adhesive materials during headlamp assembly, there was a lower potential for employee exposure to the hazardous chemicals. The authors recommend that the company move toward complete automation of this part of the production process. Levels of butyl-acetate should be checked as there was a strong smell of this chemical in part of the production line.

    Background Recurrent respiratory tract infections (RRTIs) are the most common reason for children’s visits to primary care physicians in France; however, little is known about general practitioners’ (GPs) opinions and expectations concerning the management and prevention of these common and recurrent pathologies. Purpose To describe French GPs’ daily practice in the management of respiratory infections and the prevention of their recurrence in children. Methods A sample group of French GPs answered a structured questionnaire on risk factors, RRTI management, antibiotic use and prevention measures. Results A total of 358 GPs participated in the survey. Rhinopharyngitis, the most frequent respiratory infection, was considered to be recurrent if six or more episodes occurred in a year. Four risk factors were acknowledged as substantial: living in communities, passive smoking, pollution and allergies. Around 63% of GPs said that RRTIs are too often treated with antibiotics. More than 85% thought that prevention of RRTIs is possible. Smoking cessation, vaccination, allergen avoidance and hygiene were identified as the main preventive measures. A large majority of GPs (84%) prescribed products for prevention and ~90% would prescribe a product stimulating immunity if the efficacy and tolerability of these agents was proven and confirmed in their daily practice. Conclusions French GPs are well aware of the health and socioeconomic burdens resulting from RRTIs, as well as the risk of antibiotic overuse. They have a prevention-oriented approach, implement preventive measures when possible and prescribe products for prevention. PMID:28293116

    Background Professional isolation is an important factor in low rural health workforce retention. Objective The aim of this study was to gain insights to inform the development of an implementation plan for a virtual community of practice (VCoP) for general practice (GP) training in regional Australia. The study also aimed to assess the applicability of the findings of an existing framework in developing this plan. This included ascertaining the main drivers of usage, or usefulness, of the VCoP for users and establishing the different priorities between user groups. Methods A survey study, based on the seven-step health VCoP framework, was conducted with general practice supervisors and registrars—133 usable responses; 40% estimated response rate. Data was analyzed using the t test and the chi-square test for comparisons between groups. Factor analysis and generalized linear regression modeling were used to ascertain factors which may independently predict intention to use the VCoP. Results In establishing a VCoP, facilitation was seen as important. Regarding stakeholders, the GP training provider was an important sponsor. Factor analysis showed a single goal of usefulness. Registrars had a higher intention to use the VCoP (Psupervisors. Usefulness independently predicted intention to actively use the VCoP (Psupervisors to want allied health professional and specialist involvement (Pfeedback about site activity. Regarding technology and community, training can be online, but trust is better built face-to-face. Supervisors were significantly more likely than registrars to perceive that registrars needed help with knowledge (P=.01) and implementation of knowledge (P<.001). Conclusions Important factors for a GP training VCoP include the following: facilitation covering administration and expertise, the perceived usefulness of the community, focusing usefulness around knowledge sharing, and overcoming professional isolation with high-quality content.

    Conclusion: Despite considerable investment in GP computer systems there is evidence of both under-utilisation and inefficient use. Most practices identified a number of training needs. This suggests that lack of training is a barrier to the effective use of computers. Health authorities and general practices need urgently to develop strategies to improve computer skills.

    Full Text Available Abstract Background The role of the General Practitioner (GP is central to community palliative care. Good liaison between the different professionals involved in a patient's care is extremely important in palliative care patients. In cases where GPs have previously been dissatisfied with palliative services, this may be seen as a barrier to referral when caring for other patients. The aim of this survey is to investigate the use and previous experiences of GPs of two palliative care services, with particular emphasis on barriers to referral and to explore issues surrounding the GP's role in caring for palliative patients. Methods Design: Descriptive postal survey of use and experience of palliative care services with particular emphasis on barriers to referral. Setting: One Primary Care Trust (PCT, south London, England, population 298,500. Subjects: 180 GPs in the PCT, which is served by two hospice services (A&B. Results An overall questionnaire response rate of 77% (138 was obtained, with 69% (124 used in analysis. Over 90% of GPs were satisfied with the palliative care services over the preceding two years. Two areas of possible improvement emerged; communication and prescribing practices. GPs identified some patients that they had not referred, most commonly when patients or carers were reluctant to accept help, or when other support was deemed sufficient. Over half of the GPs felt there were areas where improvement could be made; with clarification of the rules and responsibilities of the multi disciplinary team being the most common. The majority of GPs were working, and want to work with, the specialist services as part of an extended team. However, a greater number of GPs want to hand over care to the specialist services than are currently doing so. Conclusion A large number of GPs were happy with the service provision of the palliative care services in this area. They suggested that 3 out of 4 terminally ill patients needed specialist

    Full Text Available Abstract Background Staphylococcus aureus infection in patients with cystic fibrosis (CF is frequent and may be due to colonization by a few pathogenic lineages. Systematic genotyping of all isolates, methicillin-susceptible S. aureus (MSSA as well as methicillin-resistant S. aureus (MRSA is necessary to identify such lineages and follow their evolution in patients. Multiple-locus variable-number tandem repeat analysis (MLVA/VNTR was used to survey S. aureus clinical isolates in a French paediatric CF centre. Results During a 30 months period, 108 patients, aged 2 to 21 years, regularly followed up at the centre, provided sputum for culture. From 79 patients, a total of 278 isolates were genotyped by MLVA, resolving into 110 genotypes and 19 clonal complexes (CC composed of similar or closely related isolates. 71% of the strains were distributed into four main CCs, in term of number of isolates and number of genotypes. Spa (Staphylococcus protein A typing was performed on representative samples, showing an excellent concordance with MLVA. In 17 patients, strains from two to four different CCs were recovered over time. On six occasions, S. aureus isolates with the same genotype were shared by 2 different patients and they belonged to one of the four main clusters. Methicillin-resistance was observed in 60% of the isolates, 90% of which belonged to the main clonal complexes CC8, CC45 and CC5. In 5 patients, methicillin-resistance of S. aureus isolates was not associated with the mecA gene: for four patients, it was due to overproduction of β-lactamase, leading to BOR-SA (borderline S. aureus isolates, while a strain showing probably a new modified penicillin-binding capacity (MOD-SA was observed from one patient. Conclusion Systematic genotyping of S. aureus isolates recovered from sputum of CF children allows a thorough analysis of the strains responsible for sporadic as well as chronic colonization and the follow up of their evolution over time

    2010-02-01

    Following an increase in tobacco consumption among 12 to 17 year olds between 1993 and 1997, a policy mix comprising various structural and behavioral prevention measures was implemented in Germany. One element of this policy mix is the "rauchfrei" ("smoke-free") youth campaign of the BZgA (Federal Centre for Health Education), a combination of media that reaches a large number of youth, personal communication, and setting-based interventions. The aim is to prevent young people from starting to smoke and to promote the cessation of smoking at an early stage. Based on a multistage intervention model, wide coverage of the measures should be achieved among young people, as well as changes in knowledge, attitudes, social norms, and behavioral intentions. Based on the intervention model, repeated, representative cross-sectional surveys were conducted to examine the development of these indicators and of tobacco consumption. Five studies were conducted during the period from 2003 to 2008, each comprising between 1,220 and 2,780 computer-assisted telephone interviews with randomly selected young people between the ages of 12 and 17. The percentage of young people reached by information offered on the subject of not smoking rose between 2003 and 2008. Participation in school-based prevention measures also rose. There was an increase in knowledge regarding the harmful substances contained in cigarette smoke, and in the percentage of young people who rated active and passive smoking as being harmful to health. In addition, the attitude towards smoking of young people who have never smoked became more critical, as did that perceived in the social environment. The proportion of young people who smoke declined substantially, from 27.5% (2001) to 15.4% (2008), and there was been a major rise in the number who have never smoked, from 40.5% (2001) to 60.6% (2008). The change in knowledge-based risk assessments, attitudes, and social norms should be further promoted by mass media

    The measured redshift ($z$) of an astronomical object is a combination of Hubble recession, gravitational redshift and peculiar velocity. In particular, the line of sight distance to a galaxy inferred from redshift is affected by the peculiar velocity component of galaxy redshift, which can also be observed as an anisotropy in the correlation function. This anisotropy allows us to measure the linear growth rate of matter ($f\\sigma_8$). In this paper, we measure the linear growth rate of matter ($f\\sigma_8$) at $z=0.57$ using the CMASS sample from Data Release 11 of Sloan Digital Sky Survey III (SDSS III) Baryon Oscillations Spectroscopic Survey (BOSS). The galaxy sample consists of 690,826 Luminous Red Galaxies (LRGs) in the redshift range 0.43 to 0.7 covering 8498 deg$^2$. Here we report the first measurement of $f\\sigma_8$ and cosmology using Convolution Lagrangian Perturbation Theory (CLPT) with Gaussian streaming model (GSRSD). We arrive at a constraint of $f\\sigma_8=0.462\\pm0.041$ (9\\% accuracy) at effec...

    2011-07-01

    We examined the management of depression by general practitioners (GPs), through the use of case vignettes, in patients with chronic obstructive pulmonary disease (COPD), severe osteoarthritis and depressive symptoms alone. Depression is common in patients with COPD. Untreated depression leads to poor compliance with medical treatment and increases health-care utilisation. We surveyed a random sample of GPs (n = 3956) in England using a postal questionnaire. The questionnaire explored how GPs would approach the management of emotional distress in patients with and without a chronic condition and gauged their views of and experiences with depression in patients with COPD. A total of 864 completed responses were received (22%). In the vignettes, a significantly greater percentage of GPs reported that they would explore or offer the diagnosis of depression in a patient with COPD (95.4%) compared with patients with either severe osteoarthritis (88.3%) or depressive symptoms alone (86.3%). In each case, the vast majority of GPs reported that they would explore a diagnosis of depression using a clinical diagnostic tool. The preferred method of treatment, if offered, in all three cases was a combination of anti-depressant drugs and psychological therapy. GPs endorsed the importance of routinely screening for depression in patients who have COPD and acknowledged that depression impairs patient self-management of COPD.In conclusion, GPs in England were able to diagnose depression from the vignettes and plan appropriate treatment strategies in patients with chronic diseases. This should be complemented with thorough physical examination by GPs to rule out other factors such as the impact of physical illness. GPs believe depression interferes with patient self-management of COPD.

    Full Text Available Abstract Background Primary care encompasses many different clinical domains and patient groups, which means that patient safety in primary care may be equally broad. Previous research on safety in primary care has focused on medication safety and incident reporting. In this study, the views of general practitioners (GPs on patient safety were examined. Methods A web-based survey of a sample of GPs was undertaken. The items were derived from aspects of patient safety issues identified in a prior interview study. The questionnaire used 10 clinical cases and 15 potential risk factors to explore GPs' views on patient safety. Results A total of 68 GPs responded (51.5% response rate. None of the clinical cases was uniformly judged as particularly safe or unsafe by the GPs. Cases judged to be unsafe by a majority of the GPs concerned either the maintenance of medical records or prescription and monitoring of medication. Cases which only a few GPs judged as unsafe concerned hygiene, the diagnostic process, prevention and communication. The risk factors most frequently judged to constitute a threat to patient safety were a poor doctor-patient relationship, insufficient continuing education on the part of the GP and a patient age over 75 years. Language barriers and polypharmacy also scored high. Deviation from evidence-based guidelines and patient privacy in the reception/waiting room were not perceived as risk factors by most of the GPs. Conclusion The views of GPs on safety and risk in primary care did not completely match those presented in published papers and policy documents. The GPs in the present study judged a broader range of factors than in previously published research on patient safety in primary care, including a poor doctor-patient relationship, to pose a potential threat to patient safety. Other risk factors such as infection prevention, deviation from guidelines and incident reporting were judged to be less relevant than by policy

    The Second Byurakan Survey is a continuation of the Markarian survey, which aimed to reach fainter limiting magnitudes. The investigation of fainter objects, in particular QSOs, required the extension of the survey to these fainter magnitudes. The SBS survey is in fact the first simultaneous and combined survey of galaxies and quasars. The SBS objective-prism observations started in 1974 and finished in 1986. Plate searching was completed in 1991. Between 1974 and 1986 a total area of 991 square degrees of the Northern sky was observed. This area is confined to the strip defined by 7:40 right ascension and +49:00 < δ < +61:00 in declination. (5 data files).

    BACKGROUND: Refugees and asylum seekers experience language barriers in general practice. Qualitative studies have found that responses to language barriers in general practice are ad hoc with use of both professional interpreters and informal interpreters (patients\\' relatives or friends). However, the scale of the issues involved is unknown. This study quantifies the need for language assistance in general practice consultations and examines the experience of, and satisfaction with, methods of language assistance utilized. METHODS: Data were collected by telephone survey with general practitioners in a regional health authority in Ireland between July-August 2004. Each respondent was asked a series of questions about consulting with refugees and asylum seekers, the need for language assistance and the kind of language assistance used. RESULTS: There was a 70% (n = 56\\/80) response rate to the telephone survey. The majority of respondents (77%) said that they had experienced consultations with refugees and asylum seekers in which language assistance was required. Despite this, general practitioners in the majority of cases managed without an interpreter or used informal methods of interpretation. In fact, when given a choice general practitioners would more often choose informal over professional methods of interpretation despite the fact that confidentiality was a significant concern. CONCLUSION: The need for language assistance in consultations with refugees and asylum seekers in Irish general practice is high. General practitioners rely on informal responses. It is necessary to improve knowledge about the organisational contexts that shape general practitioners responses. We also recommend dialogue between general practitioners, patients and interpreters about the relative merits of informal and professional methods of interpretation so that general practitioners\\' choices are responsive to the needs of patients with limited English.

    As part of a collaborative study by the Collaborative Study Group for Micronucleus Test (CSGMT) of the Mammalian Mutagenicity Study Group (MMS) in the Japanese Environmental Mutagen Society (JEMS), the present study evaluated the effectiveness of the repeated dose liver micronucleus (RDLMN) assay. Two genotoxic hepatocarcinogens, dimethylnitrosamine (DMN) and 2-acetylaminofluorene (2-AAF), were administered orally to male rats (6 weeks old at the initial dosing) once daily for 14 and 28 days to evaluate the micronucleus (MN) inducibility in the liver. In addition, these chemicals were evaluated for MN inducibility in the bone marrow (BM) and gastrointestinal (GI) tract, i.e. glandular stomach and colon of the same animals used in the RDLMN assay. As a result, both chemicals produced positive results in the liver, although a weak positive response was given by 2-AAF. DMN gave negative results in the tissues other than the liver. 2-AAF produced positive responses in the BM and glandular stomach, and a prominent response was particularly observed in the glandular stomach, which is directly exposed to the test chemicals by gavage. The present results suggest that the RDLMN assay is a useful method for detecting genotoxic hepatocarcinogens, and that it is especially effective for evaluating test chemicals, such as DMN, undetectable by the BM and GI tract MN assay. Moreover, the results in this investigation indicate that the use of multiple tissues in the study integrating the MN tests is more effective than using a single tissue, for detection of the MN induction produced by chemical exposure to rats, and helps to determine the characteristics of the test chemicals.

    2007-01-01

    Full Text Available Abstract Background Sequencing of prokaryotic genomes has recently revealed the presence of CRISPR elements: short, highly conserved repeats separated by unique sequences of similar length. The distinctive sequence signature of CRISPR repeats can be found using general-purpose repeat- or pattern-finding software tools. However, the output of such tools is not always ideal for studying these repeats, and significant effort is sometimes needed to build additional tools and perform manual analysis of the output. Results We present PILER-CR, a program specifically designed for the identification and analysis of CRISPR repeats. The program executes rapidly, completing a 5 Mb genome in around 5 seconds on a current desktop computer. We validate the algorithm by manual curation and by comparison with published surveys of these repeats, finding that PILER-CR has both high sensitivity and high specificity. We also present a catalogue of putative CRISPR repeats identified in a comprehensive analysis of 346 prokaryotic genomes. Conclusion PILER-CR is a useful tool for rapid identification and classification of CRISPR repeats. The software is donated to the public domain.

    Full Text Available Orientation: The investigation of the psychometric properties of translated versions of a burnout measure.Research purpose: The purpose of this study was to examine the psychometric properties of translated versions of the Maslach Burnout Inventory – General Survey (MBI-GS and the Cognitive Weariness Scale.Motivation for the study: To adhere to Section 8 of the Employment Equity Act, Act No. 55 of 1998 (p. 7, which stipulates that ‘Psychological testing and other similar assessments are prohibited unless the test or assessment being used (a has been scientifi cally shown to be valid and reliable, (b can be applied fairly to all employees, and (c is not biased against any employee or group.’Research design, approach and method: The current study follows the quantitative research tradition. This study was conducted with a convenience sample of members of the South African Police Service (SAPS; N = 685. The questionnaires were translated into Afrikaans and Setswana and were administered together with the original English version.Main findings: The results indicated that a four-factor model, consisting of Exhaustion, Cynicism, Professional Effi cacy, and Cognitive Weariness or Burnout, fi tted the data best. The scales did not show measurement invariance for Afrikaans, Setswana and English samples. The reliabilities of the Exhaustion and Professional Effi cacy subscales were acceptable in the three samples.Practical/managerial implications: The implication of the results of the study under review is that the adapted MBI-GS scores obtained by the English, Afrikaans and Setswana home language speaking participants were not comparable in terms of the different translations of the instrument. Therefore, separate norms have to be developed to assess the extent of burnout experienced by the English, Afrikaans and Setswana home language speaking members of the SAPS who participated in the study.

We draw on primarily US literature to isolate three general explanatory clusters (social support, health, and economic characteristics.Based on analyses using logistic regression, the results indicate that the majority of variation in housing tenure exists due to standard demographic and household characteristics.

    The purpose of this survey was to evaluate the outcome of completing a general practice hospital-based dental residency program. A survey was mailed to all individuals who had completed a general practice residency program (resident) between 1980 and 1996 and to dentists who had not completed a hospital program (undergraduate). The responses were evaluated by Fisher's exact test. Seventy-four percent of the resident group and 68% from the undergraduate sample group returned the questionnaire. Approximately half the residents were in general dental practice. Twenty-six percent were involved in specialty dentistry, 7% in hospital dentistry, and 20% in teaching at a dental school. Of the undergraduate dentists, more than three-quarters were in general practice, 5% were entered into specialty programs, 1% were involved in hospital dentistry, and 15% taught at a dental school. Half of the residents held staff privileges in a hospital or ambulatory setting, compared with 16% of undergraduates. Forty-three percent of the residents provided consultation in a hospital or long-term-care facility, compared with 21% of the undergraduates. Practice characteristics suggested enhanced clinical skills in oral surgery, periodontics, emergency dental care, and oral medicine/pathology in those completing the hospital program. The findings of this study confirm that the outcome of completing a hospital program is a change in practice profile, site of practice, services for complex patients, and continuing involvement in teaching.

    Full Text Available Abstract Background This study was carried out to compare the HRQoL of patients in general practice with differing chronic diseases with the HRQoL of patients without chronic conditions, to evaluate the HRQoL of general practice patients in Germany compared with the HRQoL of the general population, and to explore the influence of different chronic diseases on patients' HRQoL, independently of the effects of multiple confounding variables. Methods A cross-sectional questionnaire survey including the SF-36, the EQ-5D and demographic questions was conducted in 20 general practices in Germany. 1009 consecutive patients aged 15–89 participated. The SF-36 scale scores of general practice patients with differing chronic diseases were compared with those of patients without chronic conditions. Differences in the SF-36 scale/summary scores and proportions in the EQ-5D dimensions between patients and the general population were analyzed. Independent effects of chronic conditions and demographic variables on the HRQoL were analyzed using multivariable linear regression and polynomial regression models. Results The HRQoL for general practice patients with differing chronic diseases tended to show more physical than mental health impairments compared with the reference group of patients without. Patients in general practice in Germany had considerably lower SF-36 scores than the general population (P P P Conclusion General practice patients with differing chronic diseases in Germany had impaired quality of life, especially in terms of physical health. The independent impacts on the HRQoL were different depending on the type of chronic disease. Findings from this study might help health professionals to concern more influential diseases in primary care from the patient's perspective.

    Full Text Available Including questions about sexual health in the annual Health Survey for England (HSE provides opportunities for regular measurement of key public health indicators, augmenting Britain's decennial National Survey of Sexual Attitudes and Lifestyles (Natsal. However, contextual and methodological differences may limit comparability of the findings. We examine the extent of these differences between HSE 2010 and Natsal-3 and investigate their impact on parameter estimates.Complex survey analyses of data from men and women in the 2010 HSE (n = 2,782 men and 3,588 women and Natsal-3 undertaken 2010-2012 (n = 4,882 men and 6,869 women aged 16-69y and resident in England, both using probability sampling, compared their characteristics, the amount of non-response to, and estimates from, sexual health questions. Both surveys used self-completion for the sexual behaviour questions but this was via computer-assisted self-interview (CASI in Natsal-3 and a pen-and-paper questionnaire in HSE 2010.The surveys achieved similar response rates, both around 60%, and demographic profiles largely consistent with the census, although HSE participants tended to be less educated, and reported worse general health, than Natsal-3 participants. Item non-response to the sexual health questions was typically higher in HSE 2010 (range: 9-18% relative to Natsal-3 (all <5%. Prevalence estimates for sexual risk behaviours and STI-related indicators were generally slightly lower in HSE 2010 than Natsal-3.While a relatively high response to sexual health questions in HSE 2010 demonstrates the feasibility of asking such questions in a general health survey, differences with Natsal-3 do exist. These are likely due to the HSE's context as a general health survey and methodological limitations such as its current use of pen-and-paper questionnaires. Methodological developments to the HSE should be considered so that its data can be interpreted in combination with those from dedicated

    The aim of this study is to examine the association between optimism and psychological distress in women with breast cancer after taking into account their self-rated general health. Data were aggregated from the Scottish Health Survey (2008 to 2011) to derive a nationally representative sample of 12,255 women (11,960 cancer-free controls, and 295 breast cancer cases identified from linked cancer registry data). The explanatory variables were optimism and general health, and the outcome variable was symptoms of psychological distress. Logistic regression analyses were conducted, with optimism entered in step 1 and general health entered in step 2. In an unadjusted model, higher levels of optimism were associated with lower odds of psychological distress in both the control group (OR = 0. 57, 95 % CI = 0.51-0.60) and breast cancer group (OR = 0. 64, 95 % CI = 0.47-0.88). However, in a model adjusting for general health, optimism was associated with lower odds of psychological distress only in the control group (OR = 0.50, 95 % CI = 0.44-0.57), but not significantly in the breast cancer group (OR = 1.15, 95 % CI = 0.32-4.11). In the breast cancer group, poor general health was a stronger associate of psychological distress (OR = 4. 98, 95 % CI = 1.32-18.75). Results were consistent after adjusting for age, years since breast cancer diagnosis, survey year, socioeconomic status, education, marital status, body mass index, smoking status, and alcohol consumption. This research confirms the value of multicomponent supportive care interventions for women with breast cancer. Specifically, it suggests that following breast cancer diagnosis, health care professionals need to provide advice and signpost to services that assist women to maintain or improve both their psychological and general health.

    Background Web-based surveys have become a new and popular method for collecting data, but only a few studies have directly compared postal and Web-based surveys among physicians, and none to our knowledge among general practitioners (GPs). Objective Our aim is to compare two modes of survey delivery (postal and Web-based) in terms of participation rates, response times, and completeness of questionnaires in a study assessing GPs’ preventive practices. Methods This randomized study was conducted in Western Switzerland (Geneva and Vaud) and in France (Alsace and Pays de la Loire) in 2015. A random selection of community-based GPs (1000 GPs in Switzerland and 2400 GPs in France) were randomly allocated to receive a questionnaire about preventive care activities either by post (n=700 in Switzerland, n=400 in France) or by email (n=300 in Switzerland, n=2000 in France). Reminder messages were sent once in the postal group and twice in the Web-based group. Any GPs practicing only complementary and alternative medicine were excluded from the study. Results Among the 3400 contacted GPs, 764 (22.47%, 95% CI 21.07%-23.87%) returned the questionnaire.

  6. Use of antimicrobial resistance information and prescribing guidance for management of urinary tract infections: survey of general practitioners in the West Midlands

    OpenAIRE

    2016-01-01

    Background There is a marked variation in both antibiotic prescribing practice and urine sampling rates for diagnostic microbiology across general practices in England. To help understand factors driving this variation, we undertook a survey in 2012/13 to determine sampling protocols and antibiotic formularies used by general practitioners (GPs) for managing urinary tract infections (UTIs) in the West Midlands region of England. Method Cross-sectional survey of all eligible general practices ...

    In South Korea, the number of cases of dental treatment for the disabled is gradually increasing, primarily at regional dental clinics for the disabled. This study investigated pediatric patients at a treatment clinic for the disabled within a university hospital who received dental treatment under general anesthesia. This data could assist those that provide dental treatment for the disabled and guide future treatment directions and new policies. This study was a retrospective analysis of 263 cases in which patients received dental treatment under general anesthesia from January 2011 to May 2016. The variables examined were gender, age, reason for anesthesia, type of disability, time under anesthesia, duration of treatment, type of procedure, treatment details, and annual trends in the use of general anesthesia. Among pediatric patients with disabilities who received dental treatment under general anesthesia, the most prevalent age group was 5-8 years old (124 patients, 47.1%), and the primary reason for administering anesthesia was dental anxiety or phobia. The mean time under anesthesia was 132.7 ± 77.6 min, and the mean duration of treatment was 101.9 ± 71.2 min. The most common type of treatment was restoration, accounting for 158 of the 380 treatments performed. Due to increasing demand, the number of cases of dental treatment performed under general anesthesia is expected to continue increasing, and it can be a useful method of treatment in patients with dental anxiety or phobia.

    This is the first national study of public and patient research priorities in osteoporosis and fracture. We have identified new research areas of importance to members of the public, particularly 'access to information from health professionals'. The findings are being incorporated into the research strategy of the National Osteoporosis Society. This study aimed to prioritise, with patients and public members, research topics for the osteoporosis research agenda. An e-survey to identify topics for research was co-designed with patient representatives. A link to the e-survey was disseminated to supporters of the UK National Osteoporosis Society (NOS) in a monthly e-newsletter. Responders were asked to indicate their top priority for research across four topics (understanding and preventing osteoporosis, living with osteoporosis, treating osteoporosis and treating fractures) and their top three items within each topic. Descriptive statistics were used to describe demographics and item ranking. A latent class analysis was applied to identify a substantive number of clusters with different combinations of binary responses. One thousand one hundred eighty-eight (7.4%) respondents completed the e-survey. The top three items overall were 'Having easy access to advice and information from health professionals' (63.8%), 'Understanding further the safety and benefit of osteoporosis drug treatments' (49.9%) and 'Identifying the condition early by screening' (49.2%). Latent class analysis revealed distinct clusters of responses within each topic including primary care management and self-management. Those without a history of prior fracture or aged under 70 were more likely to rate items within the cluster of self-management as important (21.0 vs 12.9 and 19.8 vs 13.3%, respectively). This is the first study of public research priorities in osteoporosis and has identified new research areas of importance to members of the public including access to information. The findings

    Full Text Available Objective To investigate the endodontic practice profile of general dental practitioners. To explore the materials and methods employed by them in Kathmandu valley. To compare these findings with well acknowledged international academic standards. Methods Questionnaires with 18 closed-ended questions were distributed among randomly chosen 120 general dental practitioners of Kathmandu, working in various government or private hospital or clinics.The data were collected and descriptive statistical analysis was done. Results Out of 120 questionnaires, only 110 that were completely filled were included in the study .Most general dental practitioners (97% regularly did multi-rooted root canal treatments and followed multivisit root canal treatment.. Radiograph with instrument in canal was used by 80% of general dental practitioners to determine the working length while only 36% used electronic apex locator which is considered to be more reliable. Half of them (57% used nickel-titanium files for cleaning and shaping but only 23% used crown down technique. Sodium hypochlorite and calcium hydroxide was the most popular irrigation solution and intra-canal medicament respectively. Majority of general dental practitioners (91% used lateral compaction technique for root canal obturation. Sixty three percent used zinc oxide eugenol as root canal sealer and 46% used endomethasone. They seem to overuse antibiotics in cases requiring endodontic therapy. Only 48% used autoclave for sterilization of endodontic files while 86% never used rubber dam. Eight three percent of them felt the need of further endodontic training and 42% of them preferred post-graduate dental program. Conclusion This study shows that the standard guidelines and new technologies for endodontic treatments are not implemented by many general dental practitioners of Kathmandu and require further endodontic trainings.

    Physical activity (PA) brief advice in health care is effective at getting individuals active. It has been suggested that one in four people would be more active if advised by a GP or nurse, but as many as 72% of GPs do not discuss the benefits of physical activity with patients. To assess the knowledge, use, and confidence in national PA and Chief Medical Officer (CMO) health guidelines and tools among GPs in England. Online questionnaire-based survey of self-selecting GPs in England that took place over a 10-day period in March 2016. The questionnaire consisted of six multiple-choice questions and was available on the Doctors.net.uk (DNUK) homepage. Quotas were used to ensure good regional representation. The final analysis included 1013 responses. Only 20% of responders were broadly or very familiar with the national PA guidelines. In all, 70% of GPs were aware of the General Practice Physical Activity Questionnaire (GPPAQ), but 26% were not familiar with any PA assessment tools, and 55% reported that they had not undertaken any training with respect to encouraging PA. The majority of GPs in England (80%) are unfamiliar with the national PA guidelines. Awareness of the recommended tool for assessment, GPPAQ, is higher than use by GPs. This may be because it is used by other clinical staff, for example, as part of the NHS Health Check programme. Although brief advice in isolation by GPs on PA will only be a part of the behaviour change journey, it is an important prompt, especially if repeated as part of routine practice. This study highlights the need for significant improvement in knowledge, skills, and confidence to maximise the potential for PA advice in GP consultations. © British Journal of General Practice 2017.

    The consultation is at the heart of general practice. It is the central setting through which primary care is delivered. The competency requirements are laid down internationally by competency-based curricula for undergraduate and postgraduate education. So far, there is no competency-based vocational training to develop consultation skills in general practice in Germany. The study describes experiences with consultation skills training as an element of general practice training as reported by trainees and trainers in Germany. A qualitative and exploring approach was chosen because there is little experience with the German situation. We conducted structured focus group interviews with trainees and trainers, respectively. We recruited all participants by e-mail via the mail distributor "Junge Allgemeinmedizin Deutschland" (JADE, a trainee and junior GP organization) and the academic teachers of the Friedrich-Alexander University Erlangen-Nürnberg. Altogether, four focus group interviews with three to five participants were conducted, varying in length from 25 to 65minutes. All interviews were recorded digitally and transcribed verbatim. Then a qualitative content analysis was performed. The statements of the ten trainees and five trainers mapped a system of four main categories: (a) association with the term consultation, (b) parts of a consultation, (c) competencies required for professional practice, (d) consultation skills training as an element of vocational training. Overall, all participants regarded the consultation as the most important element in general practice. Important content of consultations is to build a relationship with the patient, gather information, conduct physical examinations and achieve informed consent on further proceedings. All participants agreed that physicians need different sets of competencies: medical expertise, communication skills, examination skills and professionalism. Finally, there was a broad consensus that a competency

    Structure-from-motion (SfM) photogrammetry from unmanned aerial system (UAS) imagery is an emerging tool for repeat topographic surveying of dryland erosion. These methods are particularly appealing due to the ability to cover large landscapes compared to field methods and at reduced costs and finer spatial resolution compared to airborne laser scanning. Accuracy and precision of high-resolution digital terrain models (DTMs) derived from UAS imagery have been explored in many studies, typically by comparing image coordinates to surveyed check points or LiDAR datasets. In addition to traditional check points, this study compared 5 cm resolution DTMs derived from fixed-wing UAS imagery with a traditional ground-based method of measuring soil surface change called erosion bridges. We assessed accuracy by comparing the elevation values between DTMs and erosion bridges along thirty topographic transects each 6.1 m long. Comparisons occurred at two points in time (June 2014, February 2015) which enabled us to assess vertical accuracy with 3314 data points and vertical precision (i.e., repeatability) with 1657 data points. We found strong vertical agreement (accuracy) between the methods (RMSE 2.9 and 3.2 cm in June 2014 and February 2015, respectively) and high vertical precision for the DTMs (RMSE 2.8 cm). Our results from comparing SfM-generated DTMs to check points, and strong agreement with erosion bridge measurements suggests repeat UAS imagery and SfM processing could replace erosion bridges for a more synoptic landscape assessment of shifting soil surfaces for some studies. However, while collecting the UAS imagery and generating the SfM DTMs for this study was faster than collecting erosion bridge measurements, technical challenges related to the need for ground control networks and image processing requirements must be addressed before this technique could be applied effectively to large landscapes.

    Full Text Available Background: Antimicrobial resistance is associated with increased number of illness, mortality, and health care costs. The incorrect use, excessive prescription and prolonged administration of antibiotics are some factors which allow the growth of resistant bacteria leading to the emergence and spread of bacterial resistance to antibiotics. Several studies about antibiotic use have shown that behaviour towards antibiotics differs among countries, depending on culture, habits, education, and health care organization. The aim of this pilot study was to inspect the attitudes and knowledge regarding antibiotics among the public in Saudi Arabia. Methods: A cross-sectional survey using a validated questionnaire was carried out from January to February 2017 within the public, including hospital attendees and patients come for a consultation at the Prince Sattam university hospital. A total of 670 participants were included in this study. They have been chosen using a suitable sampling method. Persons incorporated in this survey who were above 18 years old and familiar with the term “antibiotics”. Results: The majority of respondents get informed about the use of antibiotics from Pharmacists (79.94%, and Physicians (76.14% and 50.3% (n=331 of the respondents reported using antibiotics six months before the survey. Regarding the source of antibiotics, (42.55% of the respondents usually gets the antibiotics after a consultation with the doctor, while 53.8% declared that their antibiotics were acquired from a retail pharmacy and a few of them (3.65% get the antibiotics from family and friends. The justification of participants for having antibiotics was mostly due to fever (41.34% or respiratory infections (22.19%. About 33.5% stated that they did not complete the treatment course and the reason was they felt better. Almost 57% indicated that they had ever kept an antibiotic at home for emergency need while 28.57% use leftover antibiotics in case they

    Dandy-Walker syndrome (DWS) is characterized by perfect or partial defect of the cerebellum vermis and cystic dilatation of the posterior fossa communicating with the fourth ventricle. Common clinical signs are mental retardation, cerebellar ataxia, and those of increased intracranial pressure (ICP). Associated congenital anomalies are craniofacial, cardiac, renal, and skeletal abnormalities. We experienced a case of intravenous sedation and six times of "the same day" general anesthesia for a school-aged boy (10-13 years old) with DWS and hypodentinogenesis. The patient underwent an examination and dental treatments. We had to pay attention to airway management tracheal tube selection and control of ICP. In addition, we should prevent tooth injuries through mishaps during tracheal intubations, since all-tooth-hypoplasia with fragile dental crowns was strongly suggested in this case. Detailed postoperative care is also required for general anesthesia afflicted with DWS.

    2017-07-04

    This study investigated professional practice and common test use among clinical neuropsychologists engaging in forensic assessment.  Doctorate-level psychologists active in the practice of neuropsychology and on the INS and NAN membership listings (n = 502) were surveyed about their demographics, professional practice, and common test use. Participants who reported engaging in forensic practice (n = 255) were further surveyed about their forensic practice. Forensic participants were more likely to be male and Caucasian, and reported higher ages, more years of professional experience, and a higher prevalence of board certification. While characteristics of their professional and forensic practice varied, forensic participants reported spending most of their professional time conducting neuropsychological assessments with adult clients in a private or group practice setting, focusing on civil referrals and civil legal questions involving older adult issues, developmental issues, head injury, and psychiatric issues. Common test use across neuropsychological assessment domains is presented for board-certified forensic participants (n = 77). An examination of these results reveals that the current pattern of test use is similar to the results of a more general survey of neuropsychological test use.  The findings provide insight into the practice of forensic neuropsychological assessment, and further establish the admissibility of neuropsychological evidence in the United States legal system. Results will be useful for clinical neuropsychologists, field leaders, and legal professionals hoping to gain insight into the role of clinical neuropsychology in civil and criminal legal decision-making.

    Complementary therapy (CT) has become increasingly popular with the general public and interest from the health professions has been rising. There has been no study focusing on the pattern of availability of CT within urban and inner-city general practice. We aimed to describe the prevalence and pattern of access to complementary therapy in this setting, identifying the characteristics of practices offering CT and the perceived barriers to service provision. We sent a postal questionnaire to all 254 general practices on the Birmingham Family Health Services Authority list. Practices were asked whether they offered any access to CTs, how services were organized and which therapies were available and to identify any barriers to provision. 175 practices (68.9%) responded. Half of the practices offered access to CT. Of these, half offered an in-house service, usually provided by the doctor (81.8%). Of GPs practising therapies themselves, 58% began in or after 1990. Seventeen separate therapies were offered, most commonly acupuncture, osteopathy, chiropractic, hypnotherapy and homoeopathy. Practices significantly more likely to offer access to CT were of larger list size and training or teaching practices. They were equally likely to be fundholders or non-fundholders. Practices offering an in-house service tended to be fundholding, training and of larger list size. Finance was perceived as the major barrier. In the area studied, many patients now have some access to CT within primary care, often within their own practice. In the main, therapies offered are the 'medically acceptable face' of complementary medicine.

    Hepatitis B is an infectious disease to which dentists are susceptible. The main aim of this study was to determine the level of antibody titer and immunity in vaccinated Iranian general dentists. A total of 861 general dentists were invited to participate in this study; 598 persons who could recall their history of vaccination and consented to have blood samples taken were recruited. Demographic and work-related data were recorded, and anti-Hepatitis B surface antigen (anti-HBs-Ag) evaluations were measured using the enzyme-linked immunosorbent assay (ELISA). Of the 598 participants, 35 (5.9%) were nonimmune (anti-HBs anti-HBs = 10-99 IU/l), and 462 (77.3%) were completely immune (anti-HBs > or =100 IU/l). Only 218 (36.5%) of the dentists knew their HBs antibody titer. Fourteen (2.3%) persons reported receiving one dose and 65 (10.9%) had received two doses. The number of those who had received the three recommended doses totaled 519 (86.8%), 491 (82.1%) of them receiving their vaccine on schedule. Age, city, pack-years of smoking, years of smoking, and the interval between the last vaccination and the commencement of the study had a significant relationship to the antibody titer level, whereas sex, marital status, place of practice, smoking, and vaccination schedule were not related. Only 36.5% of the general dentists had checked their antibody titer. We, therefore, recommend that dentists, as a potential high-risk group, should know their level of anti-HBs antibody titer so that those who require revaccination can get treatment.

    2014-10-07

    The Groningen Protocol aims at providing guidance in end-of-life decision-making for severely impaired newborns. Since its publication in 2005 many bioethicists and health care professionals have written articles in response. However, only very little is known about the opinion among the general population on this subject. The aim of this study was to present the general attitude towards neonatal euthanasia (NE) among the Austrian population and the factors associated with the respondents' opinion. A cross-sectional study was conducted among the general Austrian population. Computer-assisted telephone interviews were performed with 1,000 interviewees aged 16 years and older. Binary logistic regression was performed in order to determine factors that are independently associated with the respondents' opinion about neonatal euthanasia. While 63.6% of the participants rejected the idea of neonatal euthanasia for severely impaired newborns, 36.4% opted either in favor or were undecided. Regression analysis has shown the respondents' educational level (p = 0.005) and experience in the care of terminally ill persons (p = 0.001) to be factors that are positively associated with the rejection of neonatal euthanasia, whereas a higher age was associated with a lower degree of rejection (p = 0.021). We found that the majority of the Austrian population rejects the idea of neonatal euthanasia for severely impaired newborns. However, given the increasing levels of rejection of NE among the younger generations and among people with a higher educational level, it cannot be precluded that the rejection rate might in future increase even further, rather than decrease.

    Health-related quality of life (HRQoL) is a key measure for evaluating health status in populations. Using the recent EQ-5D-5L for measurement, this study analyzed quality of life results and their stability over consecutive population surveys. Three cross-section surveys for representative samples of the general German population from 2012, 2013, and 2014 were evaluated using the EQ-5D-5L descriptive system and valuation by the Visual Analog Scale (VAS). Aggregated sample size reached 6074. The dimension with the highest prevalence of problems was pain/discomfort (31.7%). Compared with 2012 (59.3%), the percentage of participants in the best health state increased slightly in 2013 (63.4%) and 2014 (62%). Over the 3-year period, diabetes and heart disease had the strongest negative influence on mean VAS result. The number of reported chronic diseases cumulatively reduced mean VAS. Extreme problems in one or more dimensions were stated by only 0.1%-0.2% of patients. Of the potential 247 health states with a problem score ≥ 20, only six were observed in the aggregated sample. HRQoL results were fairly stable over the 3 years, but the share of the population with no problems was not. Results from the aggregated sample may serve as updated reference values for the general German population.

    In Germany, the coverage of officially recommended vaccinations for the elderly is below a desirable level. It is known that advice provided by General Practitioners and Physician Assistants influences the uptake in patients ≥60 years. Therefore, the predictors of advice-giving behavior by these professions should be investigated to develop recommendations for possible actions for improvement. We conducted a postal cross-sectional survey on knowledge, attitudes and advice - giving behavior regarding vaccinations in the elderly among General Practitioners and Physician Assistants in 4995 practices in Germany. To find specific predictors, we performed logistic regressions with non-advising on any officially recommended vaccination or on three specific vaccinations as four separate outcomes, first using all participants, then only General Practitioners and lastly only Physician Assistants as our study population. Participants consisted of 774 General Practitioners and 563 Physician Assistants, of whom overall 21 % stated to have not advised an officially recommended vaccination in elderly patients. The most frequent explanation was having forgotten about it. The habit of not counselling on vaccinations at regular intervals was associated with not advising any vaccination (OR: 2.8), influenza vaccination (OR: 2.3), and pneumococcal vaccination (OR: 3.1). While more General Practitioners than Physician Assistants felt sufficiently informed (90 % vs. 79 %, p vaccinations (ORs: 1.8-2.8). To reduce the high risk of forgetting to advice on vaccinations, we recommend improving and promoting standing recall-systems, encouraging General Practitioners and Physician Assistants to counsel routinely at regular intervals regarding vaccinations, and providing Physician Assistants with better, tailor-made information on official recommendations and their changes.

    In 2004, we started monitoring crustal deformation at Kumano-nada in the Nankai trough using the GPS/Acoustic technique. We observed a large southward seafloor displacement of ˜30 cm associated with the off Kii Peninsula earthquake, which occurred in September 2004, between our two survey campaigns in August and November 2004. The observed seafloor displacement is larger than that predicted from a slip model derived solely from GPS measurements on land. This may indicate the earthquake fault is slightly shallower and extends move to the NW than previously estimated.

    Osteoarthritis is a leading cause of chronic pain and disability and one of the most common conditions diagnosed and managed in primary care. Despite the evidence that patients would value discussions about the course of osteoarthritis to help them make informed treatment decisions and plan for the future, little is known of GPs' practice of, or views regarding, discussing prognosis with these patients. A cross-sectional postal survey asked 2500 randomly selected UK GPs their views on discussing prognosis with patients with osteoarthritis and potential barriers or facilitators to such discussions. They were also asked if prognostic discussions were part of their current practice and what indicators they considered important in assessing the prognosis associated with osteoarthritis. Of 768 respondents (response rate 30.7 %), the majority felt it necessary to discuss prognosis with osteoarthritis patients (n = 738, 96.1 %), but only two thirds reported that it was part of their routine practice (n = 498, 64.8 %). Most respondents found predicting the course of osteoarthritis (n = 703, 91.8 %) and determining the prognosis of patients difficult (n = 589, 76.7 %). Obesity, level of physical disability and pain severity were considered the most important prognostic indicators in osteoarthritis. Although GPs consider prognostic discussions necessary for patients with osteoarthritis, few prioritise these discussions. Lack of time and perceived difficulties in predicting the disease course and determining prognosis for patients with osteoarthritis may be barriers to engaging in prognostic discussions. Further research is required to identify ways to assist GPs making prognostic predictions for patients with osteoarthritis and facilitate engagement in these discussions.

    ABSTRACT: BACKGROUND: It is ethically controversial whether medical doctors are morally permitted to ration the care of their patients at the bedside. To explore whether general practitioners in fact do ration in this manner we conducted a study within primary care in the Danish public healthcare...... of the study were twofold: an assessment of the proportion of GPs who, in a mainly hypothetical setting, would consider cost-quality trade-offs relevant to their clinical decision-making given their economic impact on the healthcare system; and a measure of the extent to which they would disclose...... this information to patients. RESULTS: In the hypothetical setting 95% of GPs considered cost-quality trade-offs relevant to their clinical decision-making given the economic impact of such trade-offs on the healthcare system. In all 90% stated that this consideration had been relevant in clinical decision...

    Chronic diseases are now among the leading causes of morbidity and mortality in lower income countries. Although traditionally related to higher individual socioeconomic status (SES) in these contexts, the associations between SES and chronic disease may be actively changing. Furthermore, country-level contextual factors, such as economic development and income inequality, may influence the distribution of chronic disease by SES as well as how this distribution has changed over time. Using overweight status as a health indicator, the authors studied repeated cross-sectional data from women aged 18-49 years in 37 developing countries to assess within-country trends in overweight inequalities by SES between 1989 and 2007 (n=405,550). Meta-regression was used to examine the associations between gross domestic product and disproportionate increases in overweight prevalence by SES, with additional testing for modification by country-level income inequality. In 27 of 37 countries, higher SES (vs. lower) was associated with higher gains in overweight prevalence; in the remaining 10 countries, lower SES (vs. higher) was associated with higher gains in overweight prevalence. Gross domestic product was positively related to faster increase in overweight prevalence among the lower wealth groups. Among countries with a higher gross domestic product, lower income inequality was associated with faster overweight growth among the poor.

    The Abdominal Compartment Syndrome (ACS) is a clinical entity recognized for over a century, but only recently its risk criteria, monitorization and treatment have been defined by the World Society of the Abdominal Compartment Syndrome (WSACS). The general surgeon's involvement is vital since this syndrome is common in surgical patients and because its treatment may culminate in a laparostomy. 250 questionnaires of 17 questions were distributed among general surgeons attending the XXVIII Portuguese Congress of Surgery. The data were analyzed using SPSS® v16. We received 36,4% (91) of the delivered questionnaires, most of which from male surgeons (63,7%), from central hospitals (75,8%), working 42 h per week (70.3%), whose average of age was 38 years. About half of the respondents received training in Intensive Care Units. All surgeons had already heard about measuring the Intra- abdominal Pressure (IAP), which was being performed at 89% of their hospitals. About 40% of surgeons only admitted intra-abdominal hypertension above 20 mmHg (only 22% indicated the correct value of 12 mmHg). 36,3% of surgeons suggested that a decompressive laparostomy must be carried out for primary ACS if IAP greater then 20 mmHg with new organ failure; 36.3% favoured the "Vacuum-pack"-like system, and 56% only re-operate the patients "as needed". 48,4% of surgeons had already performed decompressive laparostomy, 66% of which had residence training in a ICU (p = 0,005). Respondents also pointed an average mortality related to ACS of 81% without laparostomy, and a reduction to 38,5% after performing that procedure. Only 26% of the surgeons were aware of the WSACS consensus definitions and recommendations, of those, 83% had already performed a laparostomy (Pdivulgation.

    The authors conducted a study to assess the reporting quality of randomized controlled trial (RCT) abstracts published in leading general dental journals, investigate any improvement after the release of the Consolidated Standards of Reporting Trials (CONSORT) for Abstracts guidelines, and identify factors associated with better reporting quality. The authors searched PubMed for RCTs published in 10 leading general dental journals during the periods from 2005 to 2007 (pre-CONSORT period) and 2010 to 2012 (post-CONSORT period). The authors evaluated and scored the reporting quality of included abstracts by using the original 16-item CONSORT for Abstracts checklist. The authors used risk ratios and the t test to compare the adequate reporting rate of each item and the overall quality in the 2 periods. The authors used univariate and multivariate regressions to identify predictors of better reporting quality. The authors included and evaluated 276 RCT abstracts. Investigators reported significantly more checklist items during the post-CONSORT period (mean [standard deviation {SD}], 4.53 [1.69]) than during the pre-CONSORT period (mean [SD], 3.87 [1.10]; mean difference, -0.66 [95% confidence interval, -0.99 to -0.33]; P 80%). In contrast, the authors saw sufficient reporting of randomization, recruitment, outcome in the results section, and funding in none of the pre-CONSORT abstracts and less than 2% of the post-CONSORT abstracts. On the basis of the multivariate analysis, a higher impact factor (P journals has improved significantly, but there is still room for improvement. Joint efforts by authors, reviewers, journal editors, and other stakeholders to improve the reporting of dental RCT abstracts are needed. Copyright © 2015 American Dental Association.

    Australian health policy initiatives have increasingly supported the employment of nurses in general practice. An understanding of the impact of nursing care on patients in this setting is integral to assuring quality, safety and a patient-centred focus. The aim was to develop a survey to evaluate the satisfaction and enablement of patients who receive nursing care in Australian general practices. The survey was to be simple to administer and analyse, ensuring practicality for use by general practice nurses, doctors and managers. Two validated instruments formed the basis of the Patient Enablement and Satisfaction Survey (PESS). This survey was refined and validated for the Australian setting using focus groups and in-depth interviews with patients, and feedback from general practice nurses. Test-retest and alternate form methods were used to establish the survey's reliability. Feedback resulted in 14 amendments to the original draft survey. Questions that demonstrated a strong positive correlation for the test-retest and alternate form measures were included in the final survey. The PESS is a useful, practical tool for the evaluation of nursing care in Australian general practice, its validity and reliability established through a patient-centred research approach, reflective of the needs of patients accessing nursing services in this setting.

    The goal of this study is to awaken about risk occurred by CT examination. For radio-technologists working at 'S medical center' located in Seoul, we investigated a recognition about dose and risk CT and normal X-ray examination according by working experience in hospital, experience about CT examination and radiation source. For subjects of investigation, radio-technologists working at 'S medical center' located in Seoul helped us. We collected 131 questionnaires for a test of hypothesis. Cronbach coefficients of questionnaires were 0.825988 and 0.767161 and a rejection rate of p-value was below 0.05. SAS 9.1(SAS Institute Inc., Cary, NC, USA.) statistic package was used for hypothesis test. We used Mann-Whitney test, Kruskai-Wallis test, Two sample T-test, Two sample T-test with Bonferroni's Correction and One-way ANOVA methods. P-values of hypothesis about dose of CT and normal X-ray examination were 0.2291-0.9663. p-values of hypothesis about risk were 0.1924-1.0000. All of hypothesis is over rejection rate(<0.05). This study shows that radio-technologists of S medical center recognized that CT has higher dose and risk than general X-ray examination.

    2006-09-01

    Changes in the presence and absence of invertebrates as well as in species conspicuousness were documented in a rocky intertidal community based on surveys in 1984 and 2002. In 2002 six vertically and/or morphologically different stations of an intertidal platform were sampled. Five of these six habitats had already been surveyed in 1984. Replicating precisely the method of the first assessment, presence/absence changes as well as changes in species conspicuousness of 83 invertebrate species were documented, indicating that this intertidal community changed considerably during the 18-year interval. Compared with the study in 1984, 27 species newly appeared, whereas 32 species disappeared. Furthermore, 16 species increased in conspicuousness, whereas eight invertebrates decreased. The total number of species in 2002 was 154 versus 158 in 1984. Although algal species were not recorded as thoroughly as invertebrates, a massive decline in cover of Halidrys siliquosa was noted. Conversely, two invasive algal species became established after 1984, Sargassum muticum (since 1988), a cosmopolitan fucoid alga that prefers shallow subtidal areas for colonization, and Mastocarpus stellatus (introduction in the 1980s) that particularly colonized areas in the mid intertidal. In 1984 the mid intertidal zone was dominated by the brown alga Fucus serratus, whereas in 2002 the blue mussel Mytilus edulis and the periwinkle Littorina littorea were the most conspicuous organisms. Annual mean sea surface temperature (BAH measurements) warmed by 1.1°C over the past four decades. Range-related community shifts, introductions of non-indigenous species and the input of pollutants, are considered to explain long-term ecological changes in the invertebrate community at Helgoland.

    Beck, F; Richard, J-B; Léger, D

    2013-12-01

    Sleep is considered as a major protective factor for good health and quality of life. The epidemiology of chronic insomnia and other sleep disorders has recently been developed in France. The aim of this study was to evaluate total sleep time and the prevalence of chronic insomnia in the general population aged 15 to 85 years. It was also to investigate factors associated with sleep disorders. Within the framework of the Health Barometer 2010, a French general population survey, 27,653 15 to 85-year-old individuals were questioned about their health behaviors and attitudes, in particular about their sleeping time and habits. The average sleeping time of the 15 to 85-year-old was 7 hours 13 minutes. It was higher for women than for men (7 hours 18 minutes vs 7 hours 07 minutes; Psocio-demographic characteristics. Since the beginning of 1990s, a single-question inquiry on "sleeping problems present during the last 8 days" has been asked in the Health Barometer. The rate of subjects concerned increased from 1995, with a prevalence stabilized at a high level since 2000. Based on these data, we think that the surveillance of sleep disorders is an important public health issue and that prevention and health educational initiatives should be launched in the general population to promote a better quality of sleep.

    To identify occupational stressors and coping resources in a group of physiotherapists, and to analyse interactions between subjective levels of stress, efficacy in stress resolution and coping resources used by these professionals. A sample of 55 physiotherapists working in three general hospitals in Portugal completed the Coping Resources Inventory for Stress, the Occupational Stressors Inventory and two subjective scales for stress and stress resolution. Most physiotherapists perceived that they were moderately stressed (19/55, 35%) or stressed (20/55, 36%) due to work, and reported that their efficacy in stress resolution was moderate (25/54, 46%) or efficient (23/54, 42%). Issues related to lack of professional autonomy, lack of organisation in the hierarchical command chain, lack of professional and social recognition, disorganisation in task distribution and interpersonal conflicts with superiors were identified as the main sources of stress. The most frequently used coping resources were social support, stress monitoring, physical health and structuring. Perceived efficacy in stress resolution was inversely related to perceived level of occupational stress (r=-0.61, P<0.01). Significant correlations were found between several coping resources and the perceived level of stress and efficacy in stress resolution. Associations between problem solving, cognitive restructuring and stress monitoring and both low levels of perceived stress and high levels of perceived efficacy were particularly strong. The importance of identifying stressors and coping resources related to physiotherapists' occupational stress, and the need for the development of specific training programmes to cope with stress are supported.

    Full Text Available Abstract Background General Practitioners (GPs in Thailand play an important role in treating psychiatric disorders since there is a shortage of psychiatrists in the country. Our aim was to examine GP's perception of psychiatric problems, drug treatment and service problems encountered in primary care settings. Methods We distributed 1,193 postal questionnaires inquiring about psychiatric practices and service problems to doctors in primary care settings throughout Thailand. Results Four hundred and thirty-four questionnaires (36.4% were returned. Sixty-seven of the respondents (15.4% who had taken further special training in various fields were excluded from the analysis, giving a total of 367 GPs in this study. Fifty-six per cent of respondents were males and they had worked for 4.6 years on average (median = 3 years. 65.6% (SD = 19.3 of the total patients examined had physical problems, 10.7% (SD = 7.9 had psychiatric problems and 23.9% (SD = 16.0 had both problems. The most common psychiatric diagnoses were anxiety disorders (37.5%, alcohol and drugs abuse (28.1%, and depressive disorders (29.2%. Commonly prescribed psychotropic drugs were anxiolytics and antidepressants. The psychotropic drugs most frequently prescribed were diazepam among anti-anxiety drugs, amitriptyline among antidepressant drugs, and haloperidol among antipsychotic drugs. Conclusion Most drugs available through primary care were the same as what existed 3 decades ago. There should be adequate supply of new and appropriate psychotropic drugs in primary care. Case-finding instruments for common mental disorders might be helpful for GPs whose quality of practice was limited by large numbers of patients. However, the service delivery system should be modified in order to maintain successful care for a large number of psychiatric patients.

  13. Repeat-until-success quantum repeaters

    Science.gov (United States)

    Bruschi, David Edward; Barlow, Thomas M.; Razavi, Mohsen; Beige, Almut

    2014-09-01

    We propose a repeat-until-success protocol to improve the performance of probabilistic quantum repeaters. Conventionally, these rely on passive static linear-optics elements and photodetectors to perform Bell-state measurements (BSMs) with a maximum success rate of 50%. This is a strong impediment for entanglement swapping between distant quantum memories. Every time a BSM fails, entanglement needs to be redistributed between the corresponding memories in the repeater link. The key ingredients of our scheme are repeatable BSMs. Under ideal conditions, these turn probabilistic quantum repeaters into deterministic ones. Under realistic conditions, our protocol too might fail. However, using additional threshold detectors now allows us to improve the entanglement generation rate by almost orders of magnitude, at a nominal distance of 1000 km, compared to schemes that rely on conventional BSMs. This improvement is sufficient to make the performance of our scheme comparable to the expected performance of some deterministic quantum repeaters.

    The Monterey Bay Aquarium Research Institute has developed a low altitude, ROV-based seafloor mapping system that combines lidar laser ranging, multibeam sonar, and stereo photographic imagery. When operated at a 3-m altitude, this system maps seafloor topography with a 1-cm lateral resolution and simultaneously collects 2.5-mm resolution color photography. We have twice mapped an 80-m by 80-m area of a chemosynthetic clam community located at 2850-m depth in the Monterey Canyon axis. Both the topography and the photomosaics resolve changes in the clam community over a six-month interval. Many individual animals have moved, and tracks of those animals are visible in the lidar topography. No other changes in the seafloor at this site can be discerned. We have also performed single surveys of bedforms and scours at both 1850-m and 2850-m depths in Monterey Canyon. The highest resolution bathymetry data are collected using a 3DatDepth SL1 lidar laser scanner. This system has a 30° field of view and ranges continuously, achieving a 1 cm sounding spacing at a 3 m altitude and 0.3 m/s speed. Bathymetry data are also collected using a 400-kHz Reson 7125 multibeam sonar.

    Full Text Available OBJECTIVES: To determine whether current care for common shoulder problems in Australian general practice is in keeping with rheumatologist expectations and the best available evidence. METHODS: We performed a mailed survey of a random sample of 3500 Australian GPs and an online survey of all 270 rheumatologists in Australia in June 2009. Each survey included four vignettes (first presentation of shoulder pain due to rotator cuff tendinopathy, acute rotator cuff tear in a 45 year-old labourer and early and later presentation of adhesive capsulitis. For each vignette, GPs were asked to indicate their management, rheumatologists were asked to indicate appropriate primary care, and we determined best available evidence from relevant Cochrane and other systematic reviews and published guidelines. RESULTS: Data were available for at least one vignette for 614/3500 (17.5% GPs and 64 (23.8% rheumatologists. For first presentation of rotator cuff tendinopathy, 69% and 82% of GPs and 50% and 56% rheumatologists would order a shoulder X-ray and ultrasound respectively (between group comparisons P = 0.004 and P<0001. Only 66% GPs and 60% rheumatologists would refer to an orthopaedic surgeon for the acute rotator cuff tear. For adhesive capsulitis, significantly more rheumatologists recommended treatments of known benefit (e.g. glucocorticoid injection (56% versus 14%, P<0.0001, short course of oral glucocorticoids (36% versus 6%, p<0.0001 and arthrographic distension of the glenohumeral joint (41% versus 19%, P<0.0001. CONCLUSIONS: There is a mismatch between the stated management of common shoulder problems encountered in primary care by GPs, rheumatologist expectations of GP care and the available evidence.

    Background Excessive worry is required by DSM-IV, but not ICD-10, for a diagnosis of generalized anxiety disorder (GAD). No large-scale epidemiological study has ever examined the implications of this requirement for estimates of prevalence, severity, or correlates of GAD. Methods Data were analyzed from the US National Comorbidity Survey Replication, a nationally representative, face-to-face survey of adults in the US household population that was fielded in 2001–2003. DSM-IV GAD was assessed with Version 3.0 of the WHO Composite International Diagnostic Interview. Non-excessive worriers meeting all other DSM-IV criteria for GAD were compared with respondents who met full GAD criteria as well as with other survey respondents to consider the implications of removing the excessiveness requirement. Results The estimated lifetime prevalence of GAD increases by approximately 40% when the excessiveness requirement is removed. Excessive GAD begins earlier in life, has a more chronic course, and is associated with greater symptom severity and psychiatric comorbidity than non-excessive GAD. However, non-excessive cases nonetheless evidence substantial persistence and impairment of GAD as well as significantly elevated comorbidity compared to respondents without GAD. Non-excessive cases also have socio-demographic characteristics and familial aggregation of GAD comparable to excessive cases. Conclusions Although individuals who meet all criteria for GAD other than excessiveness have a somewhat milder presentation than those with excessive worry, their syndromes are sufficiently similar to those with excessive worry to warrant a GAD diagnosis.

  17. Long-term benzodiazepine and Z-drugs use in the UK: a survey of general practice.

    2017-07-17

    Current British National Formulary (BNF) guidelines state that benzodiazepines and zolpidem, zopiclone, and zaleplon, commonly known as Z-drugs (BZD), be prescribed for no more than 4 weeks, although anecdotal data suggest that many patients are prescribed BZDs for much longer. As there are no recent, evidence-based estimates of long-term (>12 months) BZD use in the UK, the scale of this potential problem is unknown. To produce the first reliable, evidence-based estimate of long-term BZD use in the UK. Estimates of UK long-term BZD use were projected from data obtained from a survey conducted in 2014-2015 by the Bridge Project, a prescribed-drug withdrawal support charity in the North of England (Bradford). Percentages of long-term users of BZD were derived from the survey, by sampling primary care GP surgeries with around 100 000 registered patients, and these were applied to UK-wide NHS patient numbers. The data were filtered to exclude the very young and old, and those with other health issues. The mean percentage of registered patients prescribed BZDs for more than a year in the survey sample is 0.69% (95% confidence interval [CI] = 0.54 to 0.84). Applying this value to national patient numbers yields a mean projection of 296 929 (95% CI = 232 553 to 361 305) long-term users of BZD in the UK. The data also suggest that as many as 119 165 of these patients may be willing to accept prescribed drug dependency withdrawal services. More than a quarter of a million people in the UK are likely to be taking highly dependency-forming hypnotic medication far beyond the recommended time scales. As there is evidence that long-term use of BZDs causes adverse physiological and neurological effects, and protracted withdrawal (with associated complications), this represents a serious public health problem. © British Journal of General Practice 2017.

    We surveyed Canadian General Surgeons to examine decision-making in early stage breast cancer. A modified Dillman Method was used for this mail survey of 1443 surgeons. Practice patterns and factors that influence management choices for: preoperative assessment, definition of margin status, surgical techniques and recommendations for re-excision were assessed. The response rate was 51% with 41% treating breast cancer. Most (80%) were community surgeons, with equal distribution of low/medium/high volume and years of practice categories. Approximately 25% of surgeons "sometimes or frequently" performed diagnostic excisional biopsies while 90% report "frequently" or "always" performing preoperative core biopsies. There was marked variation in defining negative and close margins, in the use of intra-operative margin assessment techniques and recommendations for re-excision. Responses revealed significant variation in attitudes and practices. These findings likely reflect an absence of consensus in the literature and potential gaps between best evidence and practice.

    Islam, M Ataharul

    2017-01-01

    This book presents a broad range of statistical techniques to address emerging needs in the field of repeated measures. It also provides a comprehensive overview of extensions of generalized linear models for the bivariate exponential family of distributions, which represent a new development in analysing repeated measures data. The demand for statistical models for correlated outcomes has grown rapidly recently, mainly due to presence of two types of underlying associations: associations between outcomes, and associations between explanatory variables and outcomes. The book systematically addresses key problems arising in the modelling of repeated measures data, bearing in mind those factors that play a major role in estimating the underlying relationships between covariates and outcome variables for correlated outcome data. In addition, it presents new approaches to addressing current challenges in the field of repeated measures and models based on conditional and joint probabilities. Markov models of first...

    The Physical Activity Monitor component was introduced into the 2003-2004 National Health and Nutrition Examination Survey (NHANES) to collect objective information on physical activity including both movement intensity counts and ambulatory steps. Because of an error in the accelerometer device initialization process, the steps data were missing for all participants in several primary sampling units, typically a single county or group of contiguous counties, who had intensity count data from their accelerometers. To avoid potential bias and loss in efficiency in estimation and inference involving the steps data, we considered methods to accurately impute the missing values for steps collected in the 2003-2004 NHANES. The objective was to come up with an efficient imputation method that minimized model-based assumptions. We adopted a multiple imputation approach based on additive regression, bootstrapping and predictive mean matching methods. This method fits alternative conditional expectation (ace) models, which use an automated procedure to estimate optimal transformations for both the predictor and response variables. This paper describes the approaches used in this imputation and evaluates the methods by comparing the distributions of the original and the imputed data. A simulation study using the observed data is also conducted as part of the model diagnostics. Finally, some real data analyses are performed to compare the before and after imputation results.

    Abstract:

    Background: In the Italian context, evolving toward the abandonment of compulsory vaccination, the
    maintenance of adequate levels of coverage appears as essential. The promotion of a good vaccination
    knowledge, supported by strong scientific evidence, and the collaboration of all the involved stakeholders,
    appears hence fundamental. The aim of this survey was to understand why vaccination is not appreciated
    for its real value by different stakeholders.
    Methods: In collaboration with other Italian Universities and Health Districts, in Summer 2011 we submitted
    a survey of 17 questions to a convenience sample of Italian Medical Doctors, Policy Makers and General
    Population. The main questions analyzed the importance of vaccination for health, actions to attain vaccination
    value and consequences of a free choice policy.
    Results: Of the 173 stakeholders interviewed, 78% of Medical Doctors, 82% Policy Makers and 46%
    General Population believe that vaccination is important for health. The most important actions suggested
    for strengthening vaccination were information about its efficacy and safety and studies on its impact on
    Public Health, according to most of General Population and of Medical Doctors and Policy Makers, respectively.
    According to 60.4% Medical Doctors, 72.8% Policy Makers and 56.3% General Population the abolition
    of compulsory vaccination would lead to a reduction of vaccinees in all the Italian regions.
    Conclusions: Our study confirms the need for a thorough “education in vaccination”. Among stakeholders
    there are still doubts that hinder the decision process about vaccination policies and programmes. On
    the other hand, a call for an “Alliance” for promoting and implementing vaccination to its full potential
    would be favoured, as

    Full Text Available OBJECTIVES: The aim of this study was to assess knowledge and opinions of Italian general practitioners about the effectiveness of smoking cessation interventions and physicians' attitudes in addressing tobacco-related issues. METHODS: The survey was carried out through a questionnaire administered to general practitioners (GPs attending a medical refresher course. 133 Italian GPs participated in the study with a mean age of 51.4 years (SD = 6.2. RESULTS: The GPs had good knowledge about the predictors of smoking onset, pharmacotherapies for tobacco cessation and the clinical guidelines recommendations. Wrong answers were encountered for the prevalence of smokers in Italy, the Fagerstrom Test for nicotine dependence and minimal advice. Females were more subjected to higher knowledge about tobacco, and at lower risk to be a smoker/ex smoker. Furthermore, physicians > 50 years old living in northern Italy had higher knowledge score. CONCLUSIONS: Physician education on tobacco counseling is associated to increased comfort and practice in advising patients who smoke. Tobacco cessation training might increase the success rate of helping patients to quit smoking.

    The appearance of aging skin is a common complaint among dermatology patients. There is an expanding market for anti-aging therapies, but little information is available regarding which patients utilize these treatments and patient preferences regarding treatment. To describe the patient population utilizing anti-aging therapies, assess patient familiarity with treatment options, and learn where treatment information is most often obtained. Three hundred patients were surveyed in the University of Michigan General Dermatology Clinic. Fifty-three percent of the general dermatology patient population has used an anti-aging treatment in the past; 66% reported interest in the future use. Interest is high among all genders, ages, and incomes. Most subjects obtained treatment information from magazines, but subjects were more likely to pursue treatment if information was obtained from a dermatologist. Demographics of anti-aging therapy are changing, and a wide variety of patients pursue treatment. Patients are largely unfamiliar with most treatment options and are more likely to pursue treatment after receiving treatment information from a dermatologist. The information presented in this study is helpful to both dermatologists and marketers of anti-aging products. © 2017 Wiley Periodicals, Inc.

    Results are described of a general health survey (n = 3044) that was conducted 6.5 years after the Chernobyl accident in 1986 in a seriously contaminated region in Belarus and a socioeconomically comparable, but unaffected, region in the Russian Federation. The purpose of the study was to investigate whether there are differences in the general health status of the inhabitants of the two regions that may be attributed to the Chernobyl disaster. A broad-based population sample from each of these regions was studied using a variety of self-report questionnaires. A subsample (n = 449) was further examined with a standardized physical and psychiatric examination. The results show significantly higher scores on the self-report questionnaires and higher medical service utilization in the exposed region. No significant differences were observed in global clinical indices of health. Although there were trends for some disorders to be more prevalent in the exposed region, none of these could be directly attributed to exposure to ionizing radiation. The results of this study suggest that the Chernobyl disaster had a significant long-term impact on psychological well-being, health-related quality of life, and illness behavior in the exposed population.

    The rise in electronic cigarette use by smokers may be responsible for the decreased use of licensed nicotine products and/or increased overall use of non-tobacco nicotine-containing products. This paper reports findings from the Smoking Toolkit Study (STS) tracking use of electronic cigarettes and licensed nicotine products to address this issue. Data were obtained from monthly surveys involving 14 502 cigarette smokers in England between March 2011 and November 2014. Smokers were asked about their use of electronic cigarettes and licensed nicotine products. Prevalence of electronic cigarette use increased rapidly from 2.2% (95% CI 1.4% to 3.2%) in quarter 2 of 2011 to 20.8% (95% CI 18.3% to 23.4%) in quarter 3 of 2013, after which there was no change. Prevalence of licensed nicotine product use in smokers remained stable from quarter 2 of 2011 (17.4%, 95% CI 15.3% to 19.8%) to quarter 3 of 2013 (17.9%, 95% CI 15.62% to 20.5%), and thereafter declined steadily to 7.9% (95% CI 6.0% to 10.4%). Prevalence of use of any product was stable to quarter 1 of 2012, after which it increased from 18.5% (95% CI 16.3% to 21.0%) to 33.3% (95% CI 30.4% to 36.3%) in quarter 3 of 2013, and then decreased to 22.7% (95% CI 19.3% to 26.3%). The shapes of trajectories since 2011 suggest that electronic cigarettes are probably not responsible for the decline in use of licensed nicotine products. Electronic cigarettes appear to have increased the total market for use of non-tobacco nicotine-containing products. Published by the BMJ Publishing Group Limited.

They are not intended to replace clinical judgment or medical experience, but to help physicians in the interpretation of clinical information. The general practitioner (GP, the gateway to care in the French health system, should be the main beneficiary of their utilization. However, there is no information on the prevalence of their use in general practice in France. Methods: A national, transversal epidemiological survey was conducted by electronic mail among GPs belonging to the French Sentinelles network. GPs were asked about their use of scores, the context of their utilization and the expected benefit. A qualitative study (focus groups was also carried out with three groups of GPs within the context of continuous medical education. Results: The study consisted of 358 GPs. They were questioned on their use of seven predictive clinical scores (six diagnostic and one prognostic. Clinical scores were used by 75% of GPs, with no statistical difference with regard to their age or sex. The most often used were: the Mini Mental Status Examination (MMSE (95%, Fagerström test (90%, Hamilton scale (65%, McIsaac scores (61%, DETA/CAGE (45%, Simple Calculated Osteoporosis Risk Estimation (SCORE for osteoporosis (33%, and the only prognostic score CHADS2 (28%. Clinical scores were especially used when elderly people were involved (77% and when the diagnosis was uncertain (63%.

    Full Text Available Abstract Background Serological testing for Lyme borreliosis (LB is frequently requested by general practitioners for patients with a wide variety of symptoms. Methods A survey was performed in order to characterize test utilization and clinical features of patients investigated for serum antibodies to Borrelia burgdorferi sensu lato. During one calendar year a questionnaire was sent to the general practitioners who had ordered LB serology from patients in three Danish counties (population 1.5 million inhabitants. Testing was done with a commercial ELISA assay with purified flagella antigen from a Danish strain of B. afzelii. Results A total of 4,664 patients were tested. The IgM and IgG seropositivity rates were 9.2% and 3.3%, respectively. Questionnaires from 2,643 (57% patients were available for analysis. Erythema migrans (EM was suspected in 38% of patients, Lyme arthritis/disseminated disease in 23% and early neuroborreliosis in 13%. Age 0-15 years and suspected EM were significant predictors of IgM seropositivity, whereas suspected acrodermatitis was a predictor of IgG seropositivity. LB was suspected in 646 patients with arthritis, but only 2.3% were IgG seropositive. This is comparable to the level of seropositivity in the background population indicating that Lyme arthritis is a rare entity in Denmark, and the low pretest probability should alert general practitioners to the possibility of false positive LB serology. Significant predictors for treating the patient were a reported tick bite and suspected EM. Conclusions A detailed description of the utilization of serology for Lyme borreliosis with rates of seropositivity according to clinical symptoms is presented. Low rates of seropositivity in certain patient groups indicate a low pretest probability and there is a notable risk of false positive results. 38% of all patients tested were suspected of EM, although this is not a recommended indication due to a low sensitivity of

    2007-01-01

    BACKGROUND: The desire of patients for personal continuity of care with a General Practitioner (GP) has been well documented, but not within non-registered private patients in Ireland. This study set out to examine the attitudes and reported behaviours of private fee-paying patients towards continuity of GP care and universal registration for patients. METHODS: Cross-sectional telephone survey of 400 randomly chosen fee-paying patients living within County Dublin. There is no formal system of registration with a GP for these patients. Main outcomes were attendance of respondents at primary health care facilities and their attitudes towards continuity of care and registration with a GP. Data was analysed using descriptive statistics and using parametric and non-parametric tests of association. Pearson correlation was used to quantify the association between the described variables and attitudes towards continuity and registration with a GP. Variables showing significance at the 5% level were entered into multiple linear regression models. RESULTS: 97% of respondents had seen a GP in the previous 5 years. The mean number of visits to the GP for respondents was 2.3 per annum. 89% of respondents had a regular GP and the mean length of time with their GP was 15.6 years. 96% preferred their personal medical care to be provided within one general practice. 16% of respondents had consulted a GP outside of their own practice in the previous year. They were more likely to be female, commute a longer distance to work or have poorer health status. 81% considered it important to be officially registered with a GP practice of their choice. CONCLUSION: Both personal and longitudinal continuity of care with a GP are important to private patients. Respondents who chose to visit GPs other than their regular GP were not easily characterised in this study and individual circumstances may lead to this behaviour. There is strong support for a system of universal patient registration

Materials and Methods A survey was disseminated via e-mail and on-site to 673 general dentists. The correlation between the operator's experience or preferred technique and frequency of re-use or incidence of file fracture was assessed. Results A total of 348 dentists (51.7% responded. The most frequently used NiTi instruments was ProFile (39.8% followed by ProTaper. The most preferred preparation technique was crown-down (44.6%. 54.3% of the respondents re-used NiTi files more than 10 times. There was a significant correlation between experience with NiTi files and the number of reuses (p = 0.0025. 54.6% of the respondents estimated experiencing file separation less than 5 times per year. The frequency of separation was significantly correlated with the instrumentation technique (p = 0.0003. Conclusions A large number of general dentists in Korea prefer to re-use NiTi rotary files. As their experience with NiTi files increased, the number of re-uses increased, while the frequency of breakage decreased. Operators who adopt the hybrid technique showed less tendency of separation even with the increased number of re-use.

    To evaluate the associations between population-wide loss and gain in weight with diabetes prevalence, incidence, and mortality, as well as cardiovascular and cancer mortality trends, in Cuba over a 30 year interval. Repeated cross sectional surveys and ecological comparison of secular trends. Cuba and the province of Cienfuegos, from 1980 to 2010. Measurements in Cienfuegos included a representative sample of 1657, 1351, 1667, and 1492 adults in 1991, 1995, 2001, and 2010, respectively. National surveys included a representative sample of 14 304, 22 851, and 8031 participants in 1995, 2001, and 2010, respectively. Changes in smoking, daily energy intake, physical activity, and body weight were tracked from 1980 to 2010 using national and regional surveys. Data for diabetes prevalence and incidence were obtained from national population based registries. Mortality trends were modelled using national vital statistics. Rapid declines in diabetes and heart disease accompanied an average population-wide loss of 5.5 kg in weight, driven by an economic crisis in the mid-1990s. A rebound in population weight followed in 1995 (33.5% prevalence of overweight and obesity) and exceeded pre-crisis levels by 2010 (52.9% prevalence). The population-wide increase in weight was immediately followed by a 116% increase in diabetes prevalence and 140% increase in diabetes incidence. Six years into the weight rebound phase, diabetes mortality increased by 49% (from 9.3 deaths per 10 000 people in 2002 to 13.9 deaths per 10 000 people in 2010). A deceleration in the rate of decline in mortality from coronary heart disease was also observed. In relation to the Cuban experience in 1980-2010, there is an association at the population level between weight reduction and death from diabetes and cardiovascular disease; the opposite effect on the diabetes and cardiovascular burden was seen on population-wide weight gain.

    Background Identifying essential competencies in end-of-life care, as well as general practitioners’ (GPs) confidence in these competencies, is essential to guide training and quality improvement efforts in this domain. Aim To determine which competencies in end-of-life care are considered important by GPs, to assess GPs’ confidence in these competencies in a European context and their reasons to refer terminally ill patients to a specialist. Design and Setting Cross-sectional postal survey involving a stratified random sample of 2000 GPs in Switzerland in 2014. Method Survey development was informed by a previous qualitative exploration of relevant end-of-life GP competencies. Main outcome measures were GPs’ assessment of the importance of and confidence in 18 attributes of end-of-life care competencies, and reasons for transferring care of terminally-ill patients to a specialist. GP characteristics associated with main outcome measures were tested using multivariate regression models. Results The response rate was 31%. Ninety-nine percent of GPs considered the recognition and treatment of pain as important, 86% felt confident about it. Few GPs felt confident in cultural (16%), spiritual (38%) and legal end-of-life competencies such as responding to patients seeking assisted suicide (35%) although more than half of the respondents regarded these competencies as important. Most frequent reasons to refer terminally ill patients to a specialist were lack of time (30%), better training of specialists (23%) and end-of-life care being incompatible with other duties (19%). In multiple regression analyses, confidence in end-of-life care was positively associated with GPs’ age, practice size, home visits and palliative training. Conclusions GPs considered non-somatic competencies (such as spiritual, cultural, ethical and legal aspects) nearly as important as pain and symptom control. Yet, few GPs felt confident in these non-somatic competencies. These findings

    Unprofessional behavior is common among surgical residents and faculty surgeons on Facebook. Usage of social media outlets such as Facebook and Twitter is growing at exponential rates, so it is imperative that surgery program directors (PDs) focus on professionalism within social media, and develop guidelines for their trainees and surgical colleagues. Our study focuses on the surgery PDs current approach to online professionalism within surgical education. An online survey of general surgery PDs was conducted in October 2015 through the Association for Program Directors in Surgery listserv. Baseline PD demographics, usage and approach to popular social media outlets, existing institutional policies, and formal curricula were assessed. A total of 110 PDs responded to the survey (110/259, 42.5% response rate). Social media usage was high among PDs (Facebook 68% and Twitter 40%). PDs frequently viewed the social media profiles of students, residents, and faculty. Overall, 11% of PDs reported lowering the rank or completely removing a residency applicant from the rank order list because of online behavior, and 10% reported formal disciplinary action against a surgical resident because of online behavior. Overall, 68% of respondents agreed that online professionalism is important, and that residents should receive instruction on the safe use of social media. However, most programs did not have formal didactics or known institutional policies in place. Use of social media is high among PDs, and they often view the online behavior of residency applicants, surgical residents, and faculty surgeons. Within surgical education, there needs to be an increased focus on institutional policies and standardized curricula to help educate physicians on social media and online professionalism.

    2014-06-29

    As part of the 5th National Audit Project of the Royal College of Anaesthetists and the Association of Anaesthetists of Great Britain and Ireland concerning accidental awareness during general anaesthesia, we issued a questionnaire to every consultant anaesthetist in each of 46 public hospitals in Ireland, represented by 41 local co-ordinators. The survey ascertained the number of new cases of accidental awareness becoming known to them for patients under their care or supervision for a calendar year, as well as their career experience. Consultants from all hospitals responded, with an individual response rate of 87% (299 anaesthetists). There were eight new cases of accidental awareness that became known to consultants in 2011; an estimated incidence of 1:23 366. Two out of the eight cases (25%) occurred at or after induction of anaesthesia, but before surgery; four cases (50%) occurred during surgery; and two cases (25%) occurred after surgery was complete, but before full emergence. Four cases were associated with pain or distress (50%), one after an experience at induction and three after experiences during surgery. There were no formal complaints or legal actions that arose in 2011 related to awareness. Depth of anaesthesia monitoring was reported to be available in 33 (80%) departments, and was used by 184 consultants (62%), 18 (6%) routinely. None of the 46 hospitals had a policy to prevent or manage awareness. Similar to the results of a larger survey in the UK, the disparity between the incidence of awareness as known to anaesthetists and that reported in trials warrants explanation. Compared with UK practice, there appears to be greater use of depth of anaesthesia monitoring in Ireland, although this is still infrequent.

    Background: Many international studies have been conducted to assess the knowledge, attitudes and practices (KAP) of the public toward sun exposure and sun-protection measures. However, there are scarce data on these factors from the Middle East. Objectives: This study aimed to explore the KAP of the public toward sun exposure and sun-protection measures among Saudis. Methods: A cross-sectional survey using a specially designed questionnaire was conducted on a stratified random sample of the general population in the five geographical regions of Saudi Arabia (central, eastern, northern, southern, and western). Data were collected between October 2010 and March 2011. Multiple logistic regressions were applied to relate the use of sunscreen and skin cancer awareness with various socio-demographic variables. Results: The questionnaire was distributed to 2900 Saudis. A total of 2622 questionnaires were completed, returned, and included in the data analysis, corresponding to a response rate of 90.4%. The mean (SD) age of respondents was 27.8 ± 9.7 years. Fifty percent (1301/1601) of the respondents were males. Fifty-five percent (1406/2544) were aware of the association between sun exposure and skin cancer. Female, young and student respondents were more likely to be aware of the connection between sun exposure and skin cancer (p Protective clothes were the most commonly used sun protection measure as reported by more than 90% of our participants. Conclusion: This study has shown that sun awareness and protection are generally inadequate in the Saudi population and suggests the need for health education programs.

    Patient experience and satisfaction are important indicators of quality in health care. Little is known about where to prioritize efforts to improve patient satisfaction. To investigate patient satisfaction with primary care, as part of the Quality and Costs of Primary Care in Europe study in England, identifying areas where improvements could be made from patients' perspectives. We conducted a questionnaire survey of general practice patients in three English regions. Patient Values questionnaires assessed what patients thought was important, and Patient Experience questionnaires rated performance of primary care. Fifteen attributes of care were compared using Importance Performance Analysis, a method that simultaneously represents data on importance and performance of a service, enabling identification of its strengths and weaknesses. Patients rated both 'relational' and 'functional' aspects of care as important. Satisfaction with general practice could be improved by concentrating on specific aspects of access (ensuring that patients know how to access out-of-hours services and find it easy to get an appointment), and one aspect of empowerment (after their visit, patients feel able to cope better with their health problem/illness). However, for other attributes (e.g. proximity of the practice to a patient's house or, a short waiting time when contacting the practice), investing additional resources is not likely to increase patient satisfaction. Attributes needing most improvement concerned access to primary care and patient empowerment. More research is needed to identify how to improve access without generating unnecessary additional demand or compromising continuity of care. © The Author 2016. Published by Oxford University Press.

    2014-10-01

    Chronic multiple-site joint pain (MSJP) due to osteoarthritis and soft tissue disorders is common in people over 50 years old and associated with poor outcomes. This study examined current pharmacological approaches to MSJP management in primary care. One hundred and fifty general practitioners (GPs) attending an educational seminar participated in an electronic survey (mean response rate 96%). Most GPs reported treating multiple painful joints concurrently (78%) compared with focusing on a single joint (21%). The majority believed there was no difference in analgesia for different disorders when selecting paracetamol (84%), non-steroidal anti-inflammatory drugs (NSAID)/COX-2 inhibitors (57%) or opioids (70%). When optimising therapy, intra-class optimisation (increase NSAID dose 41%, change to another NSAID/COX-2 inhibitor 30%) was preferred to inter-class step up therapy (add opioid 23%, change to opioid 6%). For NSAID gastrointestinal intolerance, the preference was to add a gastro-protective agent (74%). There is a need to better characterise MSJP and examine optimal pharmacotherapy regimens.

    The new curriculum,new ideas and new requirements concerning English teaching have made the rural English teaching face unprecedented challenges. There are many problems contributing to the poor effect of rural English teaching,such as outdated teaching equipment,unreasonable curriculum design,insufficient teaching staff,asymmetrical teaching content,family education and students’ personal problems. Based on the Chinese General Social Survey data,it is found that in terms of English reading,English speaking or English writing,the current English level of China’s rural residents is lagging behind. From the average,the reading level of rural residents is better than the speaking and writing level,but the paired T-test results show that there are no significant differences between them,suggesting that under the current system of rural English teaching,the English level of rural residents is constrained to a low level. To improve the rural English teaching in the future,it is necessary to pay close attention to the following aspects: stabilizing the investment in rural education; optimizing the English teaching content; converting the philosophy of education; increasing teacher training; establishing the new linkage system.

  3. A new standard of sexual behavior? Are claims associated with the "hookup culture" supported by general social survey data?

    Monto, Martin A; Carey, Anna G

    2014-01-01

    Popular media have described intimate relationships among contemporary college students as dominated by a pervasive sexual "hookup culture," implying that students are involved in frequent sexual encounters pursued by both participants without the expectation of a continuing relationship. The hookup culture has been described as "a nationwide phenomenon that has largely replaced traditional dating on college campuses" (Bogle, 2008 , p. 5). We tested whether these claims are supported among young adults (18-25) who had completed at least one year of college. Contrasting 1988-1996 waves of the General Social Survey with 2004-2012 waves, we found respondents from the current era did not report more sexual partners since age 18, more frequent sex, or more partners during the past year than respondents from the earlier era. Sexually active respondents from the current era were more likely than those from the earlier era to report sex with a casual date/pickup or friend, and less likely to report sex with a spouse/regular partner. These modest changes are consistent with cultural shifts in the "scripts" and terminology surrounding sexuality. We find no evidence of substantial changes in sexual behavior that would indicate a new or pervasive pattern of non-relational sex among contemporary college students.

    To examine the prevalence rate, impairment, comorbidity, course of illness and determinants of eight specific phobia variants: animals (animal subtype); heights, water, storms (natural environment subtype); flying, enclosed spaces, being alone (situational subtype); and blood/injury (blood/injury subtype). Data were obtained from the Netherlands Mental Health Survey and Incidence Study, a prospective study in the Dutch general population aged 18-65 (N = 7,076). The most prevalent condition was specific phobia with a fear of heights (4.9%). On all parameters except duration, specific phobia with a fear of being alone emerged as the most severe condition. Phobias with fear of enclosed spaces and phobias with fear of blood showed a slightly greater likelihood of impairment, comorbidity and personality problems than phobias with fear of animals, heights, water or storms. The situational and blood/injury phobia subtypes appear to be a more significant index for impairments and for comorbid psychiatric disorders than the animal and natural environment phobia subtypes.

    The objective was to evaluate the attitudes toward collaboration of nurses, general practitioners (GPs), and specialists practicing in newly established Medical Homes (MHs) in Parma Local Health Authority (LHA), Emilia-Romagna region, Italy. The 15-item Jefferson Scale of Attitudes Toward Physician-Nurse Collaboration was administered electronically to 172 physicians (66 GPs, 106 specialists) and 113 nurses practicing in 12 MHs. In all, 191 surveys (45 GPs, 59 specialists, 87 nurses) were completed (67% response rate). The mean total score among nurses (51.5, standard deviation [SD] = 3.7) reflected a significantly (P < .01) more positive attitude toward collaboration compared with GPs (47.8, SD = 4.6) and specialists (45.3, SD = 7.7). Discrepancies in attitudes are concerning because conflicting perceptions of professional roles may impede a successful transition to integrated care within MHs in Parma LHA. Internationally, further research into understanding interprofessional relationships within MHs is needed to inform policy and build a necessary culture of team-based care. © The Author(s) 2015.

  6. Limitations on quantum key repeaters.

    A major application of quantum communication is the distribution of entangled particles for use in quantum key distribution. Owing to noise in the communication line, quantum key distribution is, in practice, limited to a distance of a few hundred kilometres, and can only be extended to longer distances by use of a quantum repeater, a device that performs entanglement distillation and quantum teleportation. The existence of noisy entangled states that are undistillable but nevertheless useful for quantum key distribution raises the question of the feasibility of a quantum key repeater, which would work beyond the limits of entanglement distillation, hence possibly tolerating higher noise levels than existing protocols. Here we exhibit fundamental limits on such a device in the form of bounds on the rate at which it may extract secure key. As a consequence, we give examples of states suitable for quantum key distribution but unsuitable for the most general quantum key repeater protocol.

    Full Text Available Objectives: To clarify the views of the general population of two countries (US and Japan, concerning the handling of their medical records electronically. Methods: We contacted people nationwide in the United States at random via Random Digit Dialing (RDD to obtain 200 eligible responders. The questionnaire was for obtaining the information on their attitudes towards handling of their medical records, disclosure of the name of disease, secondary usage of information, compiling their records into a lifelong medical record, and access to their medical records on the Internet. We had also surveyed people of Shizuoka prefecture in Japan using same questionnaires sent by mail, for which we obtained 457 valid answers. Results: Even in an unidentifiable manner, US people feel profit-oriented usage of medical data without specific consent is not acceptable. There is a significant difference between usage of unidentifiable medical data for profit (about 50% feel negatively and for official/research purposes (about 30% feel negatively. About 60% of the US responders have a negative view on the proposal that unidentifiable medical information be utilized for profit by private companies to attain healthcare cost savings. As regards compiling a lifelong medical record, positive answers and negative answers are almost equally divided in the US (46% vs. 38% while more positive attitudes are seen in Japan (74% vs. 12%. However, any incentive measures aimed at changing attitudes to such a compiling including the discount of healthcare costs or insurance fees are unwelcomed by people regardless of their age or health condition in both surveys. Regarding the access to their own medical record via the Internet, 38% of the US responders feel this is unacceptable while 50.5% were willing to accept it. Conclusions: Participants from the US think that the extent of the sharing their identifiable medical records should be limited to the doctors-in-charge and specified

    Full Text Available BACKGROUND: General practitioners (GPs have a key role to play in suicide prevention, but the rates at which they question patients with depression about suicidal thoughts and plans are rather low. Little is known about GPs' characteristics associated with such inquiries. Our objectives were to describe GPs' attitudes, perceived barriers, and self-reported practices in this questioning of these patients and to analyze factors associated with these practices. METHODOLOGY: This cross-sectional survey was conducted among participants in a panel of randomly selected French GPs (1249/1431 participated: 87.3%. GPs were interviewed with a standardized questionnaire covering their professional and personal characteristics, attitudes, and practices in exploring the suicide risk of their patients with depression. We built a suicide inquiry score by summing the responses to 5 items and used a multiple linear regression analysis to explore the characteristics associated with this score. PRINCIPAL FINDINGS: Most GPs reported inquiring about the presence of suicidal ideation often or very often; less than 30% reported that they frequently explored signs of a specific suicide plan. The mean suicide inquiry score was 12.4 (SD, 2.9; range, 5-20. False ideas, such as thinking that patients who report suicidal ideas do not often commit suicide, were frequent (42.3%. Previous continuing medical education on suicide, participation in a formal mental health network, and patients who committed suicide in the past 5 years were associated with a higher score. Reluctance to question patients about suicide and perception of insufficient skill were associated with a lower score. CONCLUSIONS/SIGNIFICANCE: This study showed great variability in French GPs' practices in exploring suicide risk in patients with depression. Interventions aiming at improving GPs' initial training and continuing medical education in suicide and/or depression, and their collaboration with mental

    Middle-income countries are facing a growing challenge of adequate health care provision for people with multimorbidity. The objectives of this study were to explore the distribution of multimorbidity and to identify patterns of multimorbidity in the Brazilian general adult population. Data from 60202 adults, aged ≥18 years that completed the individual questionnaire of the National Health Survey 2013 (Portuguese: “Pesquisa Nacional de Saúde”–“PNS”) was used. We defined multimorbidity as the presence of two or more chronic conditions, including self-reported diagnoses and responses to the 9-item Patient Health Questionnaire for depression. Multivariate Poisson regression analyses were used to explore relationship between multimorbidity and demographic factors. Exploratory tetrachoric factor analysis was performed to identify multimorbidity patterns. 24.2% (95% CI 23.5–24.9) of the study population were multimorbid, with prevalence rate ratios being significantly higher in women, older people and those with lowest educational level. Multimorbidity occurred earlier in women than in men, with half of the women and men aged 55–59 years and 65–69 years, respectively, were multimorbid. The absolute number of people with multimorbidity was approximately 2.5-fold higher in people younger than 65 years than older counterparts (9920 vs 3945). Prevalence rate ratios of any mental health disorder significantly increased with the number of physical conditions. 46.7% of the persons were assigned to at least one of three identified patterns of multimorbidity, including: “cardio-metabolic”, “musculoskeletal-mental” and “respiratory” disorders. Multimorbidity in Brazil is as common as in more affluent countries. Women in Brazil develop diseases at younger ages than men. Our findings can inform a national action plan to prevent multimorbidity, reduce its burden and align health-care services more closely with patients’ needs. PMID:28182778

    Full Text Available Land use legacies can have a discernible influence in present-day watersheds and should be accounted for when designing conservation strategies for riverine aquatic life. We describe the environmental history of three watersheds within the Grande Ronde subbasin of the Columbia River using General Land Office survey field notes from the 19th century. In the two watersheds severely impacted by Euro-American land use, stream channel widths—a metric representing habitat simplification—increased from an average historical width of 16.8 m to an average present width of 20.8 m in large streams; 4.3 m to 5.5 m in small, confined or partly confined streams; and 3.5 m to 6.5 m in small, laterally unconfined steams. Conversely, we did not detect significant change in stream widths in an adjacent, wilderness stream with minimal human impact. Using a mechanistic water temperature model and restoration scenarios based on the historical condition, we predicted that stream restoration in the impacted watersheds could notably decrease average water temperatures—especially when channel narrowing is coupled with riparian restoration—up to a 6.6°C reduction in the upper Grande Ronde River and 3.0°C in Catherine Creek. These reductions in water temperature translated to substantial changes in the percentage of stream network habitable to salmon and steelhead migration (from 29% in the present condition to 79% in the fully restored scenario and to core juvenile rearing (from 13% in the present condition to 36% in the fully restored scenario. We conclude that land use legacies leave an important footprint on the present landscape and are critical for understanding historic habitat-forming processes as a necessary first step towards restoration.

    Indoor environment is important to human health and well-being. The aim of the present study was to investigate the relationships among indoor cleaning, rubbish disposal and human health and well-being in a national and population-based setting. Data was retrieved from the Japanese General Social Survey, 2010. Information on demographics, lifestyle factors, frequency of indoor cleaning and rubbish disposal and self-reported health and well-being in Japanese adults was obtained by household interview. Analysis included chi-square test, logistic and multi-nominal regression modelling. Of 5003 Japanese adults (aged 20-89) included in the study cohort, 11.4 % (n = 566) never cleaned their living place, 39.1 % had occasional cleaning and 49.6 % had frequent cleaning. Moreover, 17.5 % (n = 869) never disposed rubbish, 24.9 % had occasional rubbish disposal and 57.6 % had frequent rubbish disposal. 15.0 % of Japanese adults claimed poor self-rated health, and 5.9 % reported unhappiness. Compared to people who frequently cleaned the living place, others tended to report poor self-rated health condition (relative risk ratios (RRR) 1.52, 95 % confidence intervals (CI) 1.24-1.85, P self-rated health (RRR 2.61, 95 % CI 1.40-4.88, P = 0.003) and unhappiness (RRR 2.72, 95 % CI 1.72-4.30, P self-rated health, subjective happiness and potentially other health conditions. Public education on maintaining clean indoor environments to optimise psychological well-being in addition to the known physical health would be suggested.

  19. Repeated Surveys and Historical Nautical Charts Support Elastic Rebound Model on Megathrust at Santa MARÍA Island, Chile, (37°S) Through One and One-Half Seismic Cycles

    Repeated bathymetric surveys, historical nautical charts, geologic observations, interviews with local residents, and modern GPS measurements all support a pattern of coseismic uplift, followed by post-seismic and inter-seismic subsidence, at Santa María Island off the coast of south-central Chile. The island is located approximately 75 km landward of the Chile trench and about 12 km above the megathrust fault. Six weeks after the February 20, 1835 Concepcion earthquake (~M 8.5), Captain Robert FitzRoy and the HMS Beagle visited the island and reported 2.4-3 m of uplift based primarily on observations of elevated, newly dead, intratidal and subtidal shellfish attached to rocks. The February 27, 2010 Maule earthquake (M 8.8) earthquake produced similar effects. Several lines of evidence suggest significant subsidence between 1835 and 2010. First, the extensive wave-cut platform at the northern end of island that FitzRoy vividly describes as being exposed and covered with dead shellfish in 1835, lay at the lower level of the island’s 2-m tidal range in January 2010. The nautical chart prepared by officers of the Beagle suggests that the platform was above high tide in 1835. An elderly resident reports that in the first half of the twentieth century part of the platform was above high tide. While some lowering of the bedrock platform could be explained by erosion, the amount of required erosion would be very rapid and extensive. GPS measurements for the interval 2004-2008 indicate that the island subsided at a rate of 10 +/- 1 mm/a as well as moving landward at a rate of 42 mm/a. On January 13 and 15, 2010, we carried out a simple echo-sounder survey in the bay off the southeastern coast of Santa María Island. The same bay, Rada Santa Maria, was surveyed by the Beagle in 1835 using a lead line and pole. The bay has a smooth and very gently sloping bottom, an average depth of about 8 m, and dimensions of about 3 x 5 km. Comparison of our measured depths with those

    We present a scheme for playing quantum repeated 2x2 games based on the Marinatto and Weber's approach to quantum games. As a potential application, we study twice repeated Prisoner's Dilemma game. We show that results not available in classical game can be obtained when the game is played in the quantum way. Before we present our idea, we comment on the previous scheme of playing quantum repeated games.

    Full Text Available Abstract Background Population surveys and health services registers are the main source of data for the management of public health. Yet, the validity of survey data on the use of mental health services has been questioned repeatedly due to the sensitive nature of mental illness and to the risk of recall bias. The main objectives of this study were to compare data on the use of mental health services from a large scale population survey and a national health services register and to identify the factors associated with the discrepancies observed between these two sources of data. Methods This study was based on the individual linkage of data from the cycle 1.2 of the Canadian Community Health Survey (CCHS-1.2 and from the health services register of the Régie de l'assurance maladie du Québec (RAMQ. The RAMQ is the governmental agency managing the Quebec national health insurance program. The analyses mostly focused on the 637 Quebecer respondents who were recorded as users of mental health services in the RAMQ and who were self-reported users or non users of these services in the CCHS-1.2. Results Roughly 75%, of those recorded as users of mental health services users in the RAMQ's register did not report using mental health services in the CCHS-1.2. The odds of disagreement between survey and administrative data were higher in seniors, individuals with a lower level of education, legal or de facto spouses and mothers of young children. They were lower in individuals with a psychiatric disorder and in frequent and more recent users of mental health services according to the RAMQ's register. Conclusions These findings support the hypotheses that social desirability and recall bias are likely to affect the self-reported use of mental health services in a population survey. They stress the need to refine the investigation of mental health services in population surveys and to combine survey and administrative data, whenever possible, to obtain

    Full Text Available BACKGROUND: In developed countries, primary care physicians manage most patients with depression. Relatively few studies allow a comprehensive assessment of the decisions these doctors make in these cases and the factors associated with these decisions. We studied how general practitioners (GPs manage the acute phase of a new episode of non-comorbid major depression (MD and the factors associated with their decisions. METHODOLOGY/PRINCIPAL FINDINGS: In this cross-sectional telephone survey, professional investigators interviewed an existing panel of randomly selected GPs (1249/1431, response rate: 87.3%. We used case-vignettes about new MD episodes in 8 versions differing by patient gender and socioeconomic status (blue/white collar and disease intensity (mild/severe. GPs were randomized to receive one of these 8 versions. Overall, 82.6% chose pharmacotherapy; among them GPs chose either an antidepressant (79.8% or an anxiolytic/hypnotic alone (18.5%. They rarely recommended referral for psychotherapy alone, regardless of severity, but 38.2% chose it in combination with pharmacotherapy. Antidepressant prescription was associated with severity of depression (OR = 1.74; 95%CI = 1.33-2.27, patient gender (female, OR = 0.75; 95%CI = 0.58-0.98, GP personal characteristics (e.g. history of antidepressant treatment: OR = 2.31; 95%CI = 1.41-3.81 and GP belief that antidepressants are overprescribed in France (OR = 0.63; 95%CI = 0.48-0.82. The combination of antidepressants and psychotherapy was associated with severity of depression (OR = 1.82; 95%CI = 1.31-2.52, patient's white-collar status (OR = 1.58; 95%CI = 1.14-2.18, and GPs' dissatisfaction with cooperation with mental health specialists (OR = 0.63; 95%CI = 0.45-0.89. These choices were not associated with either GPs' professional characteristics or psychiatrist density in the GP's practice areas. CONCLUSIONS/SIGNIFICANCE: GPs' choices for

The participants stated whether they had been considerably bothered by each symptom within 14 days prior to answering the questionnaire. We used latent class analysis to identify the somatic symptom profiles. The profiles were further described by their association with age, sex, chronic disease, and self-perceived health.Results: We identified 10 different somatic symptom profiles defined by number, type, and site of the symptoms. The majority of the population (74.0% had a profile characterized by no considerable bothering symptoms, while a minor group of 3.9% had profiles defined by a high risk of multiple somatic symptoms. The remaining profiles were more likely to be characterized by a few specific symptoms. The profiles could further be described by their associations with age, sex, chronic disease, and self-perceived health.Conclusion: The identified somatic symptom profiles could be distinguished by number, type, and site of

    An extended reach EPON repeater is one of the solutions to effectively expand FTTH service areas. In this paper, we propose a reconfigurable multi-port EPON repeater for effective accommodation of multiple ODNs with a single OLT line card. The proposed repeater, which has multi-ports in both OLT and ODN sides, consists of TRs, BTRs with the CDR function and a reconfigurable electrical matrix switch, can accommodate multiple ODNs to a single OLT line card by controlling the connection of the matrix switch. Although conventional EPON repeaters require full OLT line cards to accommodate subscribers from the initial installation stage, the proposed repeater can dramatically reduce the number of required line cards especially when the number of subscribers is less than a half of the maximum registerable users per OLT. Numerical calculation results show that the extended reach EPON system with the proposed EPON repeater can save 17.5% of the initial installation cost compared with a conventional repeater, and can be less expensive than conventional systems up to the maximum subscribers especially when the percentage of ODNs in lightly-populated areas is higher.

    Transcription activator-like (TAL) effectors specifically bind to double stranded (ds) DNA through a central domain of tandem repeats. Each TAL effector (TALE) repeat comprises 33-35 amino acids and recognizes one specific DNA base through a highly variable residue at a fixed position in the repeat. Structural studies have revealed the molecular basis of DNA recognition by TALE repeats. Examination of the overall structure reveals that the basic building block of TALE protein, namely a helical hairpin, is one-helix shifted from the previously defined TALE motif. Here we wish to suggest a structure-based re-demarcation of the TALE repeat which starts with the residues that bind to the DNA backbone phosphate and concludes with the base-recognition hyper-variable residue. This new numbering system is consistent with the α-solenoid superfamily to which TALE belongs, and reflects the structural integrity of TAL effectors. In addition, it confers integral number of TALE repeats that matches the number of bound DNA bases. We then present fifteen crystal structures of engineered dHax3 variants in complex with target DNA molecules, which elucidate the structural basis for the recognition of bases adenine (A) and guanine (G) by reported or uncharacterized TALE codes. Finally, we analyzed the sequence-structure correlation of the amino acid residues within a TALE repeat. The structural analyses reported here may advance the mechanistic understanding of TALE proteins and facilitate the design of TALEN with improved affinity and specificity.

    2016-10-01

    To assess how much ENT experience regional general practitioner trainees received, both in their undergraduate and post-graduate training, and to establish if trainees felt they required further ENT training to manage ENT complaints. An online survey was emailed to general practitioner trainees in Cornwall and Devon. Of 200 general practitioner trainees, 121 (60.5 per cent) responded to the survey. Of these respondents, 95.9 per cent felt ENT experience was important as a general practitioner; however, 59.5 per cent had no ENT experience in their post-graduate training. Sixty-five per cent of trainees had not had any formal ENT teaching since leaving medical school; however, 93.4 per cent would attend a 1-day course if offered the opportunity locally. Finally, 75.8 per cent of trainees would have liked an ENT post during their post-graduate training. Further ENT training is required for doctors in general practitioner training schemes to aid improvement of patient care. The most logical way to enhance ENT training in a post-graduate setting is through up-to-date courses held locally with a faculty made up of experts working within the specialty.

    Japanese physicians' attitudes regarding the education of nurse practitioners (NPs) are not well described. A survey was mailed to 1,094 board members of the Japanese Society of Clinical Oncology (JSCO) and the Japanese Primary Care Association (JPCA), and the directors of the clinical training program for physicians. The physicians of JSCO were classified as the cancer specialist group, and both the board members of JPCA and the directors of the clinical training program for physicians constituted the general physician group. We compared the responses of cancer specialists and general physicians. The survey response rate was 25.9% (69 of 266) in the cancer specialist group and 19.4% (161 of 828) in the general physician group. The median age of respondents was 53 and 55 years, respectively, of which 84 and 79%, respectively, were men. We found that the percentages of respondents who considered NP education necessary were almost identical in the 2 groups (r = 0.898, p Education items considered necessary for NPs by >80% respondents in both groups included many symptoms, emergency management, basic procedures, general screening, palliative care including management against adverse effects, health education, and communication. More cancer specialists than general physicians (p educated in multidisciplinary practice and palliative care, including management against adverse effects. Our study suggests that cancer specialists expect NPs to provide symptom management and psychosocial support, clarify information, provide education, and work as a member of a multidisciplinary team.

    Cross-cultural differences in attitudes toward schizophrenia are suggested, while no studies have compared such attitudes between the United States and Japan. In our previous study in Japan (Hori et al., 2011), 197 subjects in the general population and 112 physicians (excluding psychiatrists) enrolled in a web-based survey using an Internet-based questionnaire format. Utilizing the identical web-based survey method in the United States, the present study enrolled 172 subjects in the general population and 45 physicians. Participants' attitudes toward schizophrenia were assessed with the English version of the 18-item questionnaire used in our previous Japanese survey. Using exploratory factor analysis, we identified four factors labeled "social distance," "belief of dangerousness," "underestimation of patients' abilities," and "skepticism regarding treatment." The two-way multivariate analysis of covariance on the four factors, with country and occupation as the between-subject factors and with potentially confounding demographic variables as the covariates, revealed that the general population in the US scored significantly lower than the Japanese counterparts on the factors "social distance" and "skepticism regarding treatment" and higher on "underestimation of patients' abilities." Our results suggest that culture may have an important role in shaping attitudes toward mental illness. Anti-stigma campaigns that target culture-specific biases are considered important.

    1990-12-01

    Doctors who were general practitioners in the period 1973-88 and had written a successful MD or PhD thesis were identified. Of 96 doctorates, 64 were MDs and 32 PhDs. Fourteen doctors had obtained their MD before becoming general practitioners and the remaining 50 after becoming general practitioners. Twenty of the 64 doctors were full time or part time members of a university department of general practice; six of these were professors. In this 16 year study the mean annual number of MDs written by doctors while in general practice was three, compared with five in the previous 15 years. Of the PhDs, 11 were obtained before starting a medical course, six during the pre-clinical period, three after qualifying but before entry into general practice and 12 after entry into general practice. Ninety two per cent of the 50 doctors who obtained their MDs while in general practice and 84% of all the doctors with MDs continued to do research afterwards. Further research was carried out by 81% of doctors with a PhD. The best way of producing good researchers in general practice is to encourage doctors to accept the challenge of writing a PhD or an MD thesis. This study has shown that writing such a thesis encourages rather than discourages a doctor to undertake further research.

    During 1991, an oral health assessment of 101 adults with developmental disabilities aged from 21 to 53 years was undertaken as part of a broader health survey which also included medical, psychological and nutritional assessments. The study group consisted of a random sample of adults chosen from the developmentally disabled population known to be living in the lower North Shore area of Sydney. This paper describes the results of the oral health assessment and compares them with an oral health survey of the Australian population done in 1987/88. Forty-six per cent of the study group were males (mean age 33.5 years) and 54 per cent were females (mean age 33.0 years). Compared with similar age subgroups in the Australian population, the following factors were more frequently reported in the developmentally disabled group: a dental visit in the last 12 months (65 per cent vs 50 per cent; Odds Ratio (OR) 1.9:95 per cent Confidence Interval (CI): 1.3-2.8); use of public rather than private dental services (42 per cent vs 6 per cent; OR 11.3:95% CI 7.5-16.9); oral mucosal pathology requiring treatment (15 per cent vs 2 per cent; OR 8.5:95% CI 5.2-13.8); severe periodontal disease (16 per cent vs 3 per cent; OR 6.9:95% CI 4.2-11.4); and moderate to severe malocclusion (26 per cent vs 11 per cent; OR 2.1:95% CI 1.3-3.5). Fifty-eight per cent of subjects felt they needed no dental treatment but on examination of the oral mucosa, periodontal tissues and teeth, over 90 per cent were found to require some sort of dental treatment.

    Knowledge surveys are a type of confidence survey in which students rate their confidence in their ability to answer questions rather than answering the questions. These surveys have been discussed as a tool to evaluate student in-class or curriculum-wide learning. However, disagreement exists as to whether confidence is actually an accurate measure of knowledge. With the concomitant goals of assessing content-based learning objectives and addressing this disagreement, we present herein a pretest/posttest knowledge survey study that demonstrates a significant difference correctness on graded test questions at different levels of reported confidence in a multi-semester timeframe. Questions were organized into Bloom's taxonomy, allowing for the data collected to further provide statistical analyses on strengths and deficits in various levels of Bloom's reasoning with regard to mean correctness. Collectively, students showed increasing confidence and correctness in all levels of thought but struggled with synthesis-level questions. However, when students were only asked to rate confidence and not answer the accompanying test questions, they reported significantly higher confidence than the control group which was asked to do both. This indicates that when students do not attempt to answer questions, they have significantly greater confidence in their ability to answer those questions. Additionally, when students rate only confidence without answering the question, resolution across Bloom's levels of reasoning is lost. Based upon our findings, knowledge surveys can be an effective tool for assessment of both breadth and depth of knowledge, but may require students to answer questions in addition to rating confidence to provide the most accurate data.

    High blood pressure (BP) is a major risk factor for cardiovascular disease. The urgency of the problem was underlined by the World Health Organization (WHO) Global Action Plan for the prevention and control of noncommunicable diseases, which recommends a 25% relative reduction in the prevalence of raised BP by 2020. A surveillance system represents a useful tool to monitor BP in the general population. Since 1980s, the National Institute of Health has conducted several surveys of the adult general population, measuring cardiovascular risk factors by standardized procedures and methods. To describe mean BP levels and high BP prevalence from 1978 to 2012 by sex and quinquennia of age. Data were derived from the following three studies: (i) Risk Factors and Life Expectancy (RIFLE), conducted between 1978 and 2002 in 13 Italian regions (>70,000 persons); (ii) Osservatorio Epidemiologico Cardiovascolare (OEC), conducted between 1998-2002 in the general population from all Italian regions (>9000 persons); and (iii) Osservatorio Epidemiologico Cardiovascolare/Health Examination Survey (OEC/HES), conducted between 2008-2012 in the general population from all Italian regions (>9000 persons). A significant decrease in mean systolic and diastolic BP levels and prevalence of high BP from 1978 to 2012 was observed both in men and women. BP and high BP increased by age classes in all considered periods. BP awareness and control also improved. Our data suggest that BP control could be achieved by 2020, as recommended by WHO.

    General practitioners (GPs) play a key role in consulting patients worried about health effects of electromagnetic fields (EMF). We compared GPs using conventional medicine (COM) with GPs using complementary and alternative medicine (CAM) concerning their perception of EMF risks. Moreover, we assessed whether the kind of alternative medicine has an influence on the results. A total of 2795 GPs drawn randomly from lists of German GPs were sent an either long or short self-administered postal questionnaire on EMF-related topics. Adjusted logistic regression models were fitted to assess the association of an education in alternative medicine with various aspects of perceiving EMF risks. Concern about EMF, misconceptions about EMF, and distrust toward scientific organizations are more prevalent in CAM-GPs. CAM-GPs more often falsely believed that mobile phone use can lead to head warming of more than 1°C (odds ratio [OR] = 2.2, 95% confidence interval [CI] = 1.5-3.3), more often distrusted the Federal Office for Radiation Protection (OR = 2.2, 95% CI = 1.4-3.6), were more often concerned about mobile phone base stations (OR = 2.4, 95% CI = 1.6-3.6), more often attributed own health complaints to EMF (OR = 3.2, 95% CI = 1.8-5.6), and more often reported at least 1 EMF consultation (OR = 2.5, 95% CI = 1.6-3.9). GPs using homeopathy perceived EMF as more risky than GPs using acupuncture or naturopathic treatment. Concern about common EMF sources is highly prevalent among German GPs. CAM-GPs perceive stronger associations between EMF and health problems than COM-GPs. There is a need for evidence-based information about EMF risks for GPs and particularly for CAM-GPs. This is the precondition that GPs can inform patients about EMF and health in line with current scientific knowledge. © The Author(s) 2014.

    Alzheimer's disease (AD) causes progressive loss of memory and disability, especially in older people. As worldwide population grows older, AD is responsible for an important social and economical burden in many nations. People suffering from AD may experience health-related stigma that influences their attitudes towards seeking assistance. The STIG-MA survey describes perceived stigma against AD in a French population. The STIG-MA questionnaire was completed anonymously by people attending an awareness campaign about AD in Creuse, France, in September 2010. Participants answered 10 questions about how they would feel or react if they had AD. Stigma scores were compared by age, activity, and interest in AD. Thirty-three percent of people attending the campaign filled out the survey. Most were women (85%) younger than 50 years (59%); 10% were older people (older than 75 years). Twenty-one percent worked in health or social fields. Interest in AD was professional (48%), related to family (41%), or personal (11%). Professionals in health fields expressed the highest levels of stigma (p = 0.02). Low stigma was most frequent in older people (p = 0.05). Type of interest did not influence stigma. Shame, loss of self-esteem, and fear of exclusion were expressed the most. The STIG-MA survey confirms that AD is a stigmatizing condition in France. The difference between perceived stigma of older people, those most exposed to AD, and that of health professionals may influence attitudes towards screening and care. Further studies of perceived stigma in these populations are necessary to adapt intervention strategies. Copyright © 2012 John Wiley & Sons, Ltd.

    The Pentapeptide Repeat Protein (PRP) family has over 500 members in the prokaryotic and eukaryotic kingdoms. These proteins are composed of, or contain domains composed of, tandemly repeated amino acid sequences with a consensus sequence of [S, T,A, V][D, N][L, F]-[S, T,R][G]. The biochemical function of the vast majority of PRP family members is unknown. The three-dimensional structure of the first member of the PRP family was determined for the fluoroquinolone resistance protein (MfpA) from Mycobacterium tuberculosis. The structure revealed that the pentapeptide repeats encode the folding of a novel right-handed quadrilateral {beta}-helix. MfpA binds to DNA gyrase and inhibits its activity. The rod-shaped, dimeric protein exhibits remarkable size, shape and electrostatic similarity to DNA.

    Objectives This study aimed to evaluate the association of neck circumference (NC) with obesity to determine the sex-specific and age-specific optimal cut-off points of this measure in association with obesity in a national sample of the Iranian paediatric population. Methods This survey on weight disorders was conducted among a national sample of Iranian children and adolescents, aged 6–18 years. Using the area under the curve (AUC) of the receiver operator characteristic curves, we evaluated the association of NC with general and abdominal obesity. Results This national survey was conducted among 23 043 school students (50.8% boys) with a mean age (SD) of 12.55 (3.31) years. A significant association was documented between NC and other anthropometric measures in both sexes and in the whole population. In all age groups and genders, NC performed relatively well in classifying participants to overweight (AUC: 0.67 to 0.75, p<0.001), general obesity (AUC: 0.81 to 0.85, p<0.001) and abdominal obesity (AUC: 0.73 to 0.78, p<0.001). Conclusions NC can be considered as a simple time-saving clinical tool for obesity detection in large population-based studies in children and adolescents. It is significantly correlated with indices of adiposity and can reliably identify children with general and abdominal obesity in the Iranian paediatric population. PMID:27694487

    This study used a confidential survey method-namely, Audio Computer-Assisted Self-Interview (ACASI)-to gather data about HIV-related risk knowledge/behaviors among the general population in Vietnam. The study sample included 1371 people aged 15 to 49 years in 3 cities-Hanoi, Da nang, and Can Tho. Results indicated that 7% of participants had ever had nonconsensual sex, and 3.6% of them had ever had a one-night stand. The percentage of male participants reported to ever have sex with sex workers was 9.6% and to ever inject drugs was 4.3%. The proportion of respondents who had ever tested for HIV was 17.6%. The risk factors and attitudes reported in the survey indicate the importance of analyzing risk behaviors related to HIV infection among the general population. Young people, especially men in more urbanized settings, are engaging in risky behaviors and may act as a "bridge" for the transmission of HIV from high-risk groups to the general population in Vietnam.

    To determine what are considered acceptable standards for animal research (AR) methodology and translation rate to humans, a validated survey was sent to: a) a sample of the general public, via Sampling Survey International (SSI; Canada), Amazon Mechanical Turk (AMT; USA), a Canadian city festival (CF) and a Canadian children's hospital (CH); b) a sample of medical students (two first-year classes); and c) a sample of scientists (corresponding authors and academic paediatricians). There were 1379 responses from the general public sample (SSI, n = 557; AMT, n = 590; CF, n = 195; CH, n = 102), 205/330 (62%) medical student responses, and 23/323 (7%, too few to report) scientist responses. Asked about methodological quality, most of the general public and medical student respondents expect that: AR is of high quality (e.g. anaesthesia and analgesia are monitored, even overnight, and 'humane' euthanasia, optimal statistical design, comprehensive literature review, randomisation and blinding, are performed), and costs and difficulty are not acceptable justifications for lower quality (e.g. costs of expert consultation, or more laboratory staff). Asked about their expectations of translation to humans (of toxicity, carcinogenicity, teratogenicity and treatment findings), most expect translation more than 60% of the time. If translation occurred less than 20% of the time, a minority disagreed that this would "significantly reduce your support for AR". Medical students were more supportive of AR, even if translation occurred less than 20% of the time. Expectations for AR are much higher than empirical data show to have been achieved.

    Full Text Available Abstract Background The use of complementary and alternative medicine (CAM is becoming more common, but population-based descriptions of its patterns of use are lacking. This study aimed to determine the prevalence of CAM use in the general population and for those with asthma, diabetes, epilepsy and migraine. Methods Data from cycles 1.1, 2.1 and 3.1 of the Canadian Community Health Survey (CCHS were used for the study. The CCHS is a national cross-sectional survey administered to 400,055 Canadians aged ≥12 between 2001-2005. Self-reported information about professionally diagnosed health conditions was elicited. CCHS surveys use a multistage stratified cluster design to randomly select a representative sample of Canadian household residents. Descriptive data on the utilization of CAM services was calculated and logistic regression was used to determine what sociodemographic factors predict CAM use. Results Weighted estimates show that 12.4% (95% Confidence Interval (CI: 12.2-12.5 of Canadians visited a CAM practitioner in the year they were surveyed; this rate was significantly higher for those with asthma 15.1% (95% CI: 14.5-15.7 and migraine 19.0% (95% CI: 18.4-19.6, and significantly lower for those with diabetes 8.0% (95% CI: 7.4-8.6 while the rate in those with epilepsy (10.3%, 95% CI: 8.4-12.2 was not significantly different from the general population. Conclusion A large proportion of Canadians use CAM services. Physicians should be aware that their patients may be accessing other services and should be prepared to ask and answer questions about the risks and benefits of CAM services in conjunction with standard medical care.

    As part of the celebration of the Journal 's 75th year, we are scanning each Journal issue from 25, 50, and 74 years ago. Many of the ideas and practices described are so similar to present-day "innovations" that George Santayana's adage (1) "Those who cannot remember the past are condemned to repeat it" comes to mind. But perhaps "condemned" is too strong - sometimes it may be valuable to repeat something that was done long ago. One example comes from the earliest days of the Division of Chemical Education and of the Journal.

    2011-09-01

    This paper explores nurses' sources of knowledge for evidence-based practice, comparing rural/remote, urban and regional participants. A cross-sectional survey of practice nurses in the state of Victoria was conducted in 2008. The instrument used was the Developing Evidence-based Practice Questionnaire - Au, distributed to a convenience sample of nurses with response of 590 (33%). Survey data were stratified by geographical location for this exploratory report. The sample was representative of practice nurses, with half employed in either regional or rural and remote areas. Rural and remote nurses were less qualified in nursing than urban nurses. However, rural, remote and regional nurses were significantly less likely to apply experiential knowledge as evidence and were more likely to source knowledge from clinical nurse specialists or nurse practitioners, local audit reports or articles in research and medical journals. Nurses in each work category reported in-service training, conferences and information shared by colleagues as important in developing their knowledge for practice. According to participants, evidence-based practice would be promoted by allocation of work time, education and training in research skills, and improved access to resources. Rural and remote practice nurses prioritised the development of their skills in sourcing and appraising evidence for practice as a strategy to facilitate knowledge translation at the point of care. © 2011 The Authors.

    Full Text Available Abstract Background The British Household Panel Survey (BHPS is the first long-running UK longitudinal survey with a non-medical focus and a sample covering the whole age range to have asked for permission to link to a range of administrative health records. This study determines whether informed consent led to selection bias and reflects on the value of the BHPS linked with health records for epidemiological research. Methods Multivariate logistical regression is used, with whether the respondent gave consent to data linkage or not as the dependent variable. Independent variables were entered as four blocks; (i a set of standard demographics likely to be found in most health registration data, (ii a broader set of socio-economic characteristics, (iii a set of indicators of health conditions and (iv information about the use of health services. Results Participants aged 16-24, males and those living in England were more likely to consent. Consent is not biased with respect to socio-economic characteristics or health. Recent users of GP services are underrepresented among consenters. Conclusions Whilst data could only be linked for a minority of BHPS participants, the BHPS offers a great range of information on people's life histories, their attitudes and behaviours making it an invaluable source for epidemiological research.

  11. The effect of question order on self-rated general health status in a multilingual survey context.

    Lee, Sunghee; Grant, David

    2009-06-15

    Current practices recommend placing a self-rated health question before specific health items in survey questionnaires to minimize potential order effects. Because this recommendation is based on data collected in English, its applicability to other languages is unknown. This study examines whether there is an order effect associated with self-rated health for interviews conducted in English and Spanish languages. An experiment was conducted by using the 2007 California Health Interview Survey, where questions on self-rated health were inserted in 1 of 2 locations: preceding and following question items on specific chronic conditions. Respondents were randomly assigned to 1 of 2 versions of the locations by the split-half method. Although no order effect was present in the English interviews, the authors found a significant and large effect with Spanish interviews: Self-rated health appeared much worse when asked before chronic conditions than when asked after them. This order effect was larger among females than males. Order effects for self-rated health differ by interview language; inferences about the health status of Spanish-speaking populations (and potentially Latinos) depend on question order. If maintaining comparability is important, the authors' finding contradicts current recommendations, as inserting the self-rated health question before specific questions led to larger differences in health status between English and Spanish speakers.

    As part of its policy of constant quality improvement, Etablissement francais du sang (EFS) des pays de la Loire (Pays de la Loire Regional Blood Transfusion Centre) carried out a satisfaction survey among the hospital personnel involved in prescribing and using immunohaematological tests and labile blood products (LBP). The polling tool selected by agreement between the Saint Nazaire's hospital management and Quality Assurance (QA) Department was a questionnaire that permitted item rating and free commentary. It addressed the personnel's perception of the quality of erythrocyte immunohaematological (EIH) testing and of the products administered, as well as their perception of the quality of communications with the local EFS. The questionnaire was sent to 26 physicians and 32 senior nurses in 15 hospital departments. The reply rate was 60% and expressed an 85% overall satisfaction level. Dissatisfaction causes were more specifically analysed, the main one involving LBP distribution in emergency situations. A joint undertaking by the EFS and the hospital led to the implementation of corrective measures, including the writing and implementation of a common standard operating procedure for emergency transfusion management. The results obtained demonstrated the feasibility of this type of survey and the interest, to a blood transfusion centre and the hospital personnel involved in transfusion, of assessing their very own perception of service quality.

    This study aims to investigate the relationship between current smoking and lifetime amount smoked and the incidence of dysphonia using data from a national cross-sectional survey that represents the Korean population. Subjects were 3,600 non-institutionalised civilian adults over the age of 19 (1,501 males and 2,099 females) who completed the laryngeal examination of the 2008 Korea National Health and Nutrition Examination Survey (KNHANES). For lifetime amount smoked, subjects were classified as light smokers (≤26.7 pack years), medium smokers (26.7-40.5 pack years), heavy smokers (40.5-55.5 pack years), and very heavy smokers (55.5-156 pack years) based on pack years (packs smoked per day × years as a smoker). The odds ratio (OR) for the statistical test was presented using hierarchical logistic regression. When adjusted for covariates (age, gender, level of education, income, occupation, alcohol consumption and pain/discomfort during the last two weeks), current smokers had a 1.8 times (OR = 1.77, 95% CI [1.17-2.68]) higher risk for self-reported voice problems than non-smokers. Moreover, current smokers had a 1.6 times (OR = 1.56, 95% CI [1.02-2.38]) higher risk of laryngeal disorder (p lifetime smoking amount and dysphonia.

    This study describes what training programs in pediatric dentistry and dental anesthesiology are doing to meet future needs for deep sedation/general anesthesia services required for pediatric dentistry. Residency directors from 10 dental anesthesiology training programs in North America and 79 directors from pediatric dentistry training programs in North America were asked to answer an 18-item and 22-item online survey, respectively, through an online survey tool. The response rate for the 10 anesthesiology training program directors was 9 of 10 or 90%. The response rate for the 79 pediatric dentistry training program directors was 46 of 79 or 58%. Thirty-seven percent of pediatric dentistry programs use clinic-based deep sedation/general anesthesia for dental treatment in addition to hospital-based deep sedation/general anesthesia. Eighty-eight percent of those programs use dentist anesthesiologists for administration of deep sedation/general anesthesia in a clinic-based setting. Pediatric dentistry residency directors perceive a future change in the need for deep sedation/general anesthesia services provided by dentist anesthesiologists to pediatric dentists: 64% anticipate an increase in need for dentist anesthesiologist services, while 36% anticipate no change. Dental anesthesiology directors compared to 2, 5, and 10 years ago have seen an increase in the requests for dentist anesthesiologist services by pediatric dentists reported by 56% of respondents (past 2 years), 63% of respondents (past 5 years), and 88% of respondents (past 10 years), respectively. Predicting the future need of dentist anesthesiologists is an uncertain task, but these results show pediatric dentistry directors and dental anesthesiology directors are considering the need, and they recognize a trend of increased need for dentist anesthesiologist services over the past decade.

    A questionnaire was mailed to 148 publicly and privately supported academic health sciences libraries affiliated with Association of American Medical Colleges (AAMC)–accredited medical schools in the United States and Canada to determine level of access and services provided to the general public. For purposes of this study, “general public” was defined as nonaffiliated students or health care professionals, attorneys and other nonhealth-related professionals, patients from affiliated or other hospitals or clinics, and general consumers. One hundred five (71%) libraries responded. Results showed 98% of publicly supported libraries and 88% of privately supported libraries provided access to some or all of the general public. Publicly supported libraries saw greater numbers of public patrons, often provided more services, and were more likely to circulate materials from their collections than were privately supported libraries. A significant number of academic health sciences libraries housed a collection of consumer-oriented materials and many provided some level of document delivery service, usually for a fee. Most allowed the public to use some or all library computers. Results of this study indicated that academic health sciences libraries played a significant role in serving the information-seeking public and suggested a need to develop written policies or guidelines covering the services that will be provided to minimize the impact of this service on primary clientele.

Methods A prospective study among all 3632 Danish GPs. The GPs were followed from the launching of the e-learning programme in November 2006 and 6 months forward. Main outcome measures: Use of the e-learning programme. A logistic regression model (GEE was used to identify predictors for use of the e-learning programme. Results In the study period, a total of 192 different GPs (5.3% were identified as users, and 17% (32 had at least one re-logon. Among responders at first login most have learnt about the e-learning programme from written material (41% or from the internet (44%. A total of 94% of the users described their ability of conducting a diagnostic evaluation as good or excellent. Most of the respondents used the e-learning programme due to general interest (90%. Predictors for using the e-learning programme were Males (OR = 1.4, 95% CI 1.1; 2.0 and members of Danish College of General Practice (OR = 2.2, 95% CI 1.5; 3.1, whereas age, experience and working place did not seem to be influential. Conclusion Only few Danish GPs used the e-learning programme in the first 6 months after the launching. Those using it were more often males and members of Danish College of General Practice. Based on this study we conclude, that an active implementation is needed, also when considering electronic formats of CME like e-learning.

To help understand factors driving this variation, we undertook a survey in 2012/13 to determine sampling protocols and antibiotic formularies used by general practitioners (GPs) for managing urinary tract infections (UTIs) in the West Midlands region of England. Cross-sectional survey of all eligible general practices in the West Midlands region of England undertaken in November 2012. GPs were invited to complete an online survey questionnaire to gather information on policies used within the practice for urine sampling for microbiological examination, and the source of antibiotic formularies used to guide treatment of UTIs. The questionnaire also gathered information on how they would manage five hypothetical clinical scenarios encountered in the community. The response rate was 11.3 % (409/3635 GPs), equivalent to a practice response rate of 26 % (248/950). Only 50 % of GPs reported having a practice policy for urine sampling. Although there was good agreement from GPs regarding collecting specimens in scenarios symbolising treatment failure (98 %), UTI in an adult male (98 %) and asymptomatic UTI in pregnancy (97 %), there was variation in GPs requesting a specimen for the scenarios involving a suspected uncomplicated urinary tract infection (UTI) and an asymptomatic catheterised elderly patient; with 40 and 38 % respectively indicating they would collect a specimen for microbiological examination. Standardised evidence based clinical management policies and antibiotic formularies for GPs should be readily available. This will promote the rational use of diagnostic microbiology services, improve antimicrobial stewardship and aid the interpretation of ongoing antimicrobial resistance surveillance.

    In four studies, we tested the hypothesis that a General Factor of Personality (GFP) occupies the apex of the hierarchy. In Study 1, a GFP was found in 16 sets of Big Five inter-scale correlations (N = 6412) which explained 54% of the variance in the two first-order factors. In Study 2, a GFP was found in validation samples from the Guilford-Zimmerman Temperament Survey (N = 2917) which explained 36% of the variance in three first-order factors and 21% of the total reliable variance in a mode...

    Congenital generalized lipodystrophy (CGL) is a rare genetic disease characterized by the absence of body fat from birth. Focal bone lesions have also been reported, but their pathophysiology is poorly understood. To characterize skeletal abnormalities further in 3 patients with CGL, we employed whole-body radiographic skeletal surveys, magnetic resonance imaging (MRI, including gadolinium enhancement), and triple phase technetium-99m methylene diphosphonate bone scintigraphy. We conclude that the appendicular skeleton of patients with CGL is diffusely abnormal and is predisposed to focal osteolysis and cyst formation. (orig./DG).

    Full Text Available Abstract Background Infant feeding recommendations for HIV-positive mothers differ from recommendations to mothers of unknown HIV-status. The aim of this study was to compare feeding practices, including breastfeeding, between infants and young children of HIV-positive mothers and infants of mothers in the general population of Uganda. Methods This study compares two cross-sectional surveys conducted in the end of 2003 and the beginning of 2005 in Eastern Uganda using analogous questionnaires. The first survey consisted of 727 randomly selected general-population mother-infant pairs with unknown HIV status. The second included 235 HIV-positive mothers affiliated to The Aids Support Organisation, TASO. In this article we compare early feeding practices, breastfeeding duration, feeding patterns with dietary information and socio-economic differences in the two groups of mothers. Results Pre-lacteal feeding was given to 150 (64% infants of the HIV-positive mothers and 414 (57% infants of general-population mothers. Exclusive breastfeeding of infants under the age of 6 months was more common in the general population than among the HIV-positive mothers (186 [45%] vs. 9 [24%] respectively according to 24-hour recall. Mixed feeding was the most common practice in both groups of mothers. Solid foods were introduced to more than half of the infants under 6 months old among the HIV-positive mothers and a quarter of the infants in the general population. Among the HIV-positive mothers with infants below 12 months of age, 24 of 90 (27% had stopped breastfeeding, in contrast to 9 of 727 (1% in the general population. The HIV-positive mothers were poorer and had less education than the general-population mothers. Conclusion In many respects, HIV-positive mothers fed their infants less favourably than mothers in the general population, with potentially detrimental effects on both the child's nutrition and the risk of HIV transmission. Mixed feeding and pre

    Full Text Available This study aims to investigate the relationship between current smoking and lifetime amount smoked and the incidence of dysphonia using data from a national cross-sectional survey that represents the Korean population. Subjects were 3,600 non-institutionalised civilian adults over the age of 19 (1,501 males and 2,099 females who completed the laryngeal examination of the 2008 Korea National Health and Nutrition Examination Survey (KNHANES. For lifetime amount smoked, subjects were classified as light smokers (≤26.7 pack years, medium smokers (26.7–40.5 pack years, heavy smokers (40.5–55.5 pack years, and very heavy smokers (55.5–156 pack years based on pack years (packs smoked per day × years as a smoker. The odds ratio (OR for the statistical test was presented using hierarchical logistic regression. When adjusted for covariates (age, gender, level of education, income, occupation, alcohol consumption and pain/discomfort during the last two weeks, current smokers had a 1.8 times (OR = 1.77, 95% CI [1.17–2.68] higher risk for self-reported voice problems than non-smokers. Moreover, current smokers had a 1.6 times (OR = 1.56, 95% CI [1.02–2.38] higher risk of laryngeal disorder (p < 0.05. In terms of pack years, very heavy smokers were significantly more likely to have laryngeal disorder, while self-reported voice problems were significantly more likely for heavy smokers but not very heavy smokers. The results of this study imply that chronic smoking has a significant relationship with dysphonia. Longitudinal studies are required in future work to verify the causality between lifetime smoking amount and dysphonia.

    Full Text Available Abstract Background Upper respiratory tract infections (URTIs are among the most frequent reasons for physician office visits in paediatrics. Despite their predominant viral aetiology, URTIs continue to be treated with antimicrobials. We explored general practitioners' (GPs prescribing behaviour for antimicrobials in children (≤ 16 years with URTIs in Trinidad, using the guidelines from the Centers for Disease Control and Prevention (CDC as a reference. Methods A cross-sectional study was conducted on 92 consenting GPs from the 109 contacted in Central and East Trinidad, between January to June 2003. Using a pilot-tested questionnaire, GPs identified the 5 most frequent URTIs they see in office and reported on their antimicrobial prescribing practices for these URTIs to trained research students. Results The 5 most frequent URTIs presenting in children in general practice, are the common cold, pharyngitis, tonsillitis, sinusitis and acute otitis media (AOM in rank order. GPs prescribe at least 25 different antibiotics for these URTIs with significant associations for amoxicillin, co-amoxiclav, cefaclor, cefuroxime, erythromycin, clarithromycin and azithromycin (p 30 years were more likely to prescribe antibiotics for the common cold (p = 0.014. Severity (95.7% and duration of illness (82.5% influenced doctors' prescribing and over prescribing in general practice was attributed to parent demands (75% and concern for secondary bacterial infections (70%. Physicians do not request laboratory investigations primarily because they are unnecessary (86% and the waiting time for results is too long (51%. Conclusions Antibiotics are over prescribed for paediatric URTIs in Trinidad and amoxicillin with co-amoxiclav were preferentially prescribed. Except for AOM, GPs' prescribing varied from the CDC guidelines for drug and duration. Physicians recognise antibiotics are overused and consider parents expecting antibiotics and a concern for secondary

    It has been recommended that screening for sexually transmitted disease (STDs) be carried out at the time of termination of pregnancy to allow prevention of post-abortion infection. Screening offers the opportunity to treat an infected woman and prevent serious complications following the termination procedure. Our findings indicate that general practitioners (GPs) in South Thames did not routinely carry out screening and few realized it took place at referral centres. PMID:9624755

    Full Text Available Abstract Background Approximately one in ten of the UK population are unpaid carers supporting a family member or friend who could not manage without their help, saving the UK economy an estimated £87 billion. This role is known to sometimes have a negative impact on carers and to require support both informally and from statutory services. General practice is a first point of contact for carers but research investigating general practitioners' (GPs' attitudes towards carers and awareness of issues facing carers is rare. This study therefore aimed to identify GPs' attitudes, awareness of issues, and perceptions of the barriers and enablers to provision of services. Methods Using a self-completion questionnaire distributed at a series of workshops, this study investigates GPs' attitudes to carers; awareness and knowledge of carers' issues; services offered in general practice and barriers to supporting carers. Results Seventy eight out of a total of 95 GPs (82% response rate from a variety of areas in England completed the questionnaires. The GPs identified time, resources and lack of knowledge as barriers, but only 9% agreed with the statement that there is little support they can offer carers. However, nine in ten GPs (89% feel they have insufficient training here and approximately half of them (47% lack confidence that they are meeting carers' needs. Confidence in identifying carers is also low (45%. Issues that GPs would look out for amongst carers include emotional and physical health problems and financial and isolation difficulties. GPs specifically highlighted educational and isolation issues for young carers. Few services were described that targeted carers. Conclusions GPs recognise that they have an important role to play in supporting carers but would like training and support. Further investigation is needed both to determine how best to train and facilitate GPs and general practice teams in their role in supporting carers and to

    The objective of this study was to evaluate the general practitioners' (GPs') knowledge and perceptions towards generic medicines in a northern state of Malaysia. A postal cross-sectional survey involving registered GPs in Penang, Malaysia was undertaken. A 23-item questionnaire was developed, validated and administered on the GPs. Eighty-seven GPs responded to the survey (response rate 26.8%). The majority of the respondents (85.1%) claimed that they actively prescribed generic medicines in their practice. On the other hand, only 4.6% of the respondents correctly identified the Malaysia's National Pharmaceutical Control Bureau's bioequivalence standard for generic products. There were misconceptions among the respondents about the concepts of "bioequivalence", "efficacy", "safety", and "manufacturing standards" of generic medicines. GPs in this survey believed that a standard guideline on brand substitution process, collaboration with pharmacists, patient education and information on safety and efficacy of generic medicines were necessary to ensure quality use of generics. Furthermore, advertisements and product bonuses offered by pharmaceutical companies, patient's socio-economic factors as well as credibility of manufacturers were factors reported to influence their choice of medicine. Although it appeared that GPs have largely accepted the use of generic medicines, they still have concerns regarding the reliability and quality of such products. GPs need to be educated and reassured about generic products approval system in Malaysia concerning bioequivalence, quality, and safety. The current findings have important implications in establishing generic medicines policy in Malaysia. Copyright (c) 2009 Elsevier Ireland Ltd. All rights reserved.

    The purpose of this study was to evaluate the practice and depth of knowledge of root canal treatment by general dental practitioners working in private dental centers in different cities within the Kingdom of Saudi Arabia. A questionnaire was distributed to 400 general dental practitioners. Completed questionnaires were analyzed in term of simple summary statistics. A total of 252 (63%) practitioners responded. The majority of the respondents were Syrians (59%) and Egyptians (32%). Ninety-one per cent of the respondents indicated that they performed root canal treatment. Amongst those who carried out root canal treatment, only seven practitioners (3%) used rubber dam for isolation. More than half of the respondents (55%) used saline to irrigate canals during treatment. Forty-six per cent of practitioners used formocresol as an inter appointment medicament. The standardized and step-back preparation techniques were the method of choice for the majority of the respondents (91%). Ninety-seven per cent of the practitioners used stainless steel hand instruments to prepare root canals and the majority (92%) used gutta-percha for obturation. Seventy-four per cent of the respondent used cold lateral condensation. The average number of radiographs routinely taken for root canal treatment was four. Ninety-three per cent indicated that they usually completed a root canal treatment of molar teeth in three or more visits. Eighty-eight per cent of the practitioners preferred waiting for 1 or 2 weeks to restore the teeth permanently. Results of this study confirm that many general dental practitioners are not following quality guidelines for endodontic treatment. PMID:23960485

    Unmanned aerial vehicles (UAVs) have gained significant attention in recent years. Low-cost platforms using inexpensive sensor payloads have been shown to provide satisfactory flight and navigation capabilities. In this report, we survey vision and control methods that can be applied to low-cost UAVs, and we list some popular inexpensive platforms and application fields where they are useful. We also highlight the sensor suites used where this information is available. We overview, among others, feature detection and tracking, optical flow and visual servoing, low-level stabilization and high-level planning methods. We then list popular low-cost UAVs, selecting mainly quadrotors. We discuss applications, restricting our focus to the field of infrastructure inspection. Finally, as an example, we formulate two use-cases for railway inspection, a less explored application field, and illustrate the usage of the vision and control techniques reviewed by selecting appropriate ones to tackle these use-cases. To select vision methods, we run a thorough set of experimental evaluations. PMID:26121608

    Background Previous studies have shown heavier drinkers are less likely to respond to surveys and require extended efforts to recruit. This study applies the continuum of resistance model to explore how survey estimates of alcohol consumption may be affected by non-response bias in three consecutive years of a general population survey in England. Methods Using the Health Survey for England (HSE) survey years 2011–13, number of contact attempts (1–6 and 7+) were explored by socio-demographic and drinking characteristics. The odds of drinking more than various thresholds were modelled using logistic regression. Assuming that non-participants were similar to those who were difficult to contact (the continuum of resistance model), the effect of non-response on measures of drinking was investigated. Results In the fully-adjusted regression model, women who required 7+ calls were significantly more likely to drink more than the UK Government’s recommended daily limit (OR 1.19, 95% CI 1.06–1.33, P = 0.003) and to engage in heavy episodic drinking (OR 1.23, 95% CI 1.07–1.42, P = 0.004), however this was not significant in men in the fully-adjusted model. When the continuum of resistance model was applied, there was an increase in average weekly alcohol consumption of 1.8 units among men (a 12.6% relative increase), and an increase of 1.5 units among women (a 20.5% relative increase). There was also an increase in the prevalence of heavy episodic drinking of 2.5% among men (an 12.0% relative increase) and of 2.0% among women (a 15.8% relative increase), although other measures of drinking were less affected. Conclusion Overall alcohol consumption and the prevalence of heavy episodic drinking were higher among HSE participants who required more extended efforts to contact. The continuum of resistance model suggests non-response bias does affect survey estimates of alcohol consumption. PMID:28141834

    2010-05-25

    Abstract Background Sexual problems are common among people with coronary heart disease and can adversely affect patients\\' quality of life. GPs are ideally placed to deal with these problems. Research suggests that GPs are reluctant to address sexual problems but little is known about what currently takes place in practice. The aim of this study was to examine GPs\\' self-reported behaviour and attitudes to discussing sexual problems with people with coronary heart disease. Method Design: A cross-sectional survey which administered 230 postal questionnaires to a nationally representative, stratified random sample of GPs in the Republic of Ireland. GPs were asked about current practice, knowledge, awareness and confidence in dealing with sexual problems, barriers to addressing sexual problems, and about improving services in this area. Results Responses were available for 61 GPs (27% response rate). Seventy percent of GPs reported that they rarely or never discussed sexual problems with coronary patients. While all GPs believed addressing sexual problems was important, many GPs reported lacking awareness, knowledge and confidence in addressing sexual problems. The main barriers were lack of time, feeling the patient wasn\\'t ready and lack of training in the area. GPs wanted more training and guidelines for practice. Conclusions There is currently no standardised protocol for GPs for dealing with sexual problems among coronary patients. Awareness of these issues appears to be low among GPs. Services could be improved by developing practice guidelines for brief, effective actions or assessments, providing training in the area and improving information resources and support services for referral.

    The goal of this study is to investigate whether speaking other than home languages in Sub-Saharan Africa promotes generalized trust. Based on various psychological and economic theories, a simple model is provided to illustrate how languages might shape trust through various channels. Relying on data from the Afrobarometer Project, which provides information on home and additional languages, the Index of Communication Potential (ICP) is introduced to capture the linguistic situation in the 20 sample countries. The ICP, which can be computed at any desired level of aggregation, refers to the probability that an individual can communicate with a randomly selected person in the society based on common languages. The estimated two-level hierarchical models show that, however, individual level communication potential does not seem to impact trust formation, but living in an area with higher average communication potential increases the chance of exhibiting higher trust toward unknown people.

    Duct leakage often needs to be measured to demonstrate compliance with requirements or to determine energy or Indoor Air Quality (IAQ) impacts. Testing is often done using standards such as ASTM E1554 (ASTM 2013) or California Title 24 (California Energy Commission 2013 & 2013b), but there are several choices of methods available within the accepted standards. Determining which method to use or not use requires an evaluation of those methods in the context of the particular needs. Three factors that are important considerations are the cost of the measurement, the accuracy of the measurement and the repeatability of the measurement. The purpose of this report is to evaluate the repeatability of the three most significant measurement techniques using data from the literature and recently obtained field data. We will also briefly discuss the first two factors. The main question to be answered by this study is to determine if differences in the repeatability of these tests methods is sufficient to indicate that any of these methods is so poor that it should be excluded from consideration as an allowed procedure in codes and standards.

    Full Text Available Abstract Background In this study we evaluated the usefulness of a free self-test for screening albuminuria in the general population. Methods Dutch adults were invited by the Dutch Kidney Foundation to order a free albuminuria self-test, consisting of three semi quantitative dipstick tests, via the Internet. Results were classified in negative, low-positive and high-positive. In case of a positive test result, the tester was recommended to visit a GP for supplementary examination and/or treatment. Participants of the programme were sent a questionnaire for evaluation by e-mail eight weeks after receiving the self-test. Results During the first 30 days of the self-test programme, 996,927 self-tests were ordered. In total, 71,714 participants completed the questionnaire: 79% had a negative test result and 21% had a positive test result (20% low-positive and 1% high-positive. Of the positive testers, 25% visited a GP after testing for albuminuria. Among the 3,983 participants who visited a GP, 193 new diseases were detected: 25 chronic renal failure, 152 hypertension and 31 diabetes mellitus. Conclusion Using a free self-test for screening albuminuria in the general population resulted in a large response and a number of newly detected diseases. However, we found a very high percentage of positive testers of which probably a large part is false positive. Furthermore, only a small part of the positive testers visited a GP for additional examination and/or treatment. The efficiency of such a campaign could be increased by embedding the testing in health care to reduce the number of false-positive results and to ensure follow-up and treatment in case of a positive test result.

    Full Text Available Abstract Background In order to get sickness benefit a sick-listed person need a medical certificate issued by a physician; in Sweden after one week of self-certification. Physicians experience sick-listing tasks as problematic and conflicts may arise when patients regard themselves unable to work due to complaints that are hard to objectively verify for the physician. Most GPs and orthopaedic surgeons (OS deal regularly with sick-listing issues in their daily practice. The aim of this study was to explore perceived problems and coping strategies related to tasks of sickness certification among general practitioners (GP and orthopaedic surgeons (OS. Methods A cross-sectional study about sickness certification in two Swedish counties, with 673 participating GPs and 149 OSs, who answered a comprehensive questionnaire. Frequencies together with crude and adjusted (gender and working years Odds ratios were calculated. Results A majority of the GPs and OSs experienced problems in sickness certification every week. To assess the patient's work ability, to handle situations when they and the patient had different opinions about the need for sickness absence, and to issue prolongation certificates when the previous was issued by another physician were reported as problematic by a majority in both groups. Both GPs and OSs prolonged sickness certifications due to waiting times in health care or at Social Insurance Office (SIO. To handle experienced problems they used different strategies; OSs issued sickness certificates without personal appointment more often than the GPs, who on the other hand reported having contact with SIO more often than the OSs. A higher rate of GPs experienced support from management and had a common strategy for handling sickness certification at the clinic than the OSs. Conclusion Most GPs and OSs handled sickness certification weekly and reported a variety of problems in relation to this task, generally GPs to a higher extent

    This study aimed to identify the anatomical items of the upper extremity and spine that are potentially relevant to the practice of rheumatology. Ten rheumatologists interested in clinical anatomy who published, taught, and/or participated as active members of Clinical Anatomy Interest groups (six seniors, four juniors), participated in a one-round relevance Delphi exercise. An initial, 560-item list that included 45 (8.0 %) general concepts items; 138 (24.8 %) hand items; 100 (17.8 %) forearm and elbow items; 147 (26.2 %) shoulder items; and 130 (23.2 %) head, neck, and spine items was compiled by 5 of the participants. Each item was graded for importance with a Likert scale from 1 (not important) to 5 (very important). Thus, scores could range from 10 (1 × 10) to 50 (5 × 10). An item score of ≥40 was considered most relevant to competent practice as a rheumatologist. Mean item Likert scores ranged from 2.2 ± 0.5 to 4.6 ± 0.7. A total of 115 (20.5 %) of the 560 initial items reached relevance. Broken down by categories, this final relevant item list was composed by 7 (6.1 %) general concepts items; 32 (27.8 %) hand items; 20 (17.4 %) forearm and elbow items; 33 (28.7 %) shoulder items; and 23 (17.6 %) head, neck, and spine items. In this Delphi exercise, a group of practicing academic rheumatologists with an interest in clinical anatomy compiled a list of anatomical items that were deemed important to the practice of rheumatology. We suggest these items be considered curricular priorities when training rheumatology fellows in clinical anatomy skills and in programs of continuing rheumatology education.

    The aim of the study was to explore, in the Malaysian general population: knowledge and beliefs of the characteristics in general of medication-related side effects and side effects associated with different types of medicines; behaviour related to the safe use of drugs before and after taking a medication; and behaviour in the event of a medication-related side effect. A 24-item self-administered questionnaire was developed and used to survey the general public living or working in suburban Kuala Lumpur, Malaysia. Eight hundred questionnaires were distributed, face to face, by researchers using quota sampling. Respondents' knowledge, belief and behaviour were analysed and correlated with demographics, medical history and experience of side effects. Six hundred and ten respondents completed the questionnaire giving a response rate of 76.3%. The mean knowledge score for the respondents was 18.4±3.6 out of the maximum possible score of 26. Educational level and experience of side effect had an influence on the knowledge score obtained. Respondents had misconceptions regarding the safety of complementary and alternative medicines (CAMs) and over-the-counter medications. Medication history and previous experience with side effects had a significant influence on the higher behaviour score obtained. The survey has shown moderate results with regard to the knowledge of public regarding safety of medications, and there was evidence of under-estimating the risk of medications, especially CAMs. The misconceptions among the public, and inappropriate behaviour on drug safety-related aspects, is a concern which needs to be addressed in the interventions designed. © 2011 The Authors.

    Full Text Available This study aimed to determine and compare the prevalences of diabetes awareness, treatment, and adequate glycemic control among cancer survivors in a Korean population and two non-cancer control groups, comprising individuals without a history of cancer but with other chronic diseases (non-cancer, chronic disease controls and individuals without a history of cancer or any other chronic disease (non-cancer, non-chronic disease controls.We analyzed data from 2,660 subjects with prevalent diabetes (aged ≥30 years, who had participated in the 2007-2011 Korea National Health and Nutrition Examination Survey. Awareness was defined as a subject having been diagnosed with diabetes by a clinician. Treatment was defined as a subject who was taking anti-diabetic medicine. Adequate glycemic control was defined as a hemoglobin A1c level of <7%. Multivariable logistic regression and predictive margins were used to evaluate whether awareness, treatment, or adequate glycemic control differed among cancer survivors and the two non-cancer control groups.Cancer survivors had greater awareness compared with the non-cancer, chronic disease and non-cancer, non-chronic disease control groups (85.1%, 80.4%, and 60.4%, respectively. Although the prevalences of treatment and adequate glycemic control were higher for survivors compared with the non-cancer, non-chronic disease controls, they were lower compared with the non-cancer, chronic disease controls. The prevalence of diabetes treatment was 67.5% for cancer survivors, 69.5% for non-cancer, chronic disease controls, and 46.7% for non-cancer, non-chronic disease controls; the prevalences of adequate glycemic control in these three groups were 31.7%, 34.6%, and 17.8%, respectively.Cancer survivors were less likely than the non-cancer chronic disease subjects to receive diabetes management and to achieve adequate glycemic targets. Special attention and education are required to ensure that this population receives

    BACKGROUND: Increased use of prostate specific antigen (PSA) has been associated with increased prostate cancer incidence. Ireland is estimated to have one of the highest prostate cancer incidences in Europe and has no national guidelines for prostate cancer screening. GPs have a pivotal role in influencing PSA testing, therefore, our aim was to describe GP testing practices and to identify factors influencing these. METHODS: A postal survey, including questions on clinical practice and experience, knowledge and demographics was distributed to all GPs (n = 3,683). The main outcomes were (i) PSA testing asymptomatic men and (ii) "inappropriate" PSA testing, defined as testing asymptomatic men aged < 50 or > 75 years. Factors associated with these outcomes were identified using logistic regression. RESULTS: 1,625 GPs responded (response rate corrected for eligibility = 53%). Most respondents (79%) would PSA test asymptomatic men. Of these, 34% and 51% would test asymptomatic men < 50 and > 75 years, respectively. In multivariate analyses, GPs were more likely to test asymptomatic men if they were >or= 50 years, in practice >or= 10 years, female or less knowledgeable about PSA efficacy. Male GPs who would have a PSA test themselves were > 8-times more likely to PSA test asymptomatic men than GPs who would not have a test. GPs who had an asymptomatic patient diagnosed with prostate cancer following PSA testing, were > 3-times more likely to test asymptomatic men. Practice-related factors positively associated with testing included: running \\'well man\\' clinics, performing occupational health checks and performing other tests routinely with PSA. Factors positively associated with \\'inappropriate\\' testing included; being male and willing to have a PSA test, having worked\\/trained in the UK and supporting annual PSA testing. 91% of respondents supported the development of national PSA testing guidelines. CONCLUSION: Our findings suggest that widespread PSA testing

    Full Text Available Abstract Background General dental practitioners provide the majority of endodontic treatment in Jordan. The aim of this study was to gather information on the methods, materials and attitudes employed in root canal treatment by dentists in North Jordan, in order to evaluate and improve the quality of current practice. Methods A questionnaire was posted to all registered general dental practitioners working in private practice in Irbid Governate in North Jordan (n = 181. The questionnaire included information on methods, materials and techniques used in endodontic treatment. Results Reply rate was 72% (n = 131. The results demonstrated that only five dentists used rubber dam occasionally and not routinely. The majority used cotton rolls for isolation solely or in combination with a high volume saliva ejector (n = 116. The most widely used irrigants were sodium hypochlorite and hydrogen peroxide, which were used by 32.9% (n = 43 and 33.6% (n = 44 of the respondents, respectively. Forty eight percent of the respondents (n = 61 used the cold lateral condensation technique for canal obturation, 31.3% (n = 41 used single cone, 9.9% (n = 13 used vertical condensation and 12.2% (n = 16 used paste or cement only for the obturation. The majority used zinc oxide eugenol as a sealer (72.5%. All, but one, respondents used hand instruments for canal preparation and the technique of choice was step back (52.7%. More than 50% (n = 70 of the dentists took one radiograph for determining the working length, whilst 22.9% (n = 30 did not take any radiograph at all. Most practitioners performed treatment in three visits for teeth with two or more root canals, and in two visits for teeth with a single root canal. Conclusions This study indicates that dentists practicing in North Jordan do not comply with international quality standards and do not use recently introduced techniques. Many clinicians never take a radiograph for determining the working length and never

    Full Text Available The purpose of this study was to evaluate the general attitude of senior dental students towards rubber dam use, specifically focusing on endodontic practices prior to starting to serve community. Questionnaires were distributed to senior year students of a private school and a state school in Istanbul. Questions were asked about areas where the students used rubber dam, its advantages and difficulties, and whether they agreed or disagreed with some aspects of the rubber dam. The private school students rated isolation whereas those of the state school selected prevention of aspiration which the top advantage rubber dam provides. Students of the state school agreed with the opinion that isolation cannot be achieved without rubber dam and it extended the procedure with a significantly higher ratio compared to the private school. Within the limitations of the present study, it can be concluded that the perceptions of dental students on rubber dam needs to be improved and strategies should be developed so that this valuable adjunct will comprise one of the indispensable elements of dental care.

    2016-10-01

    Smoking has been associated with an important health risk. The aim was to analyze the health-related quality of life (HRQoL) status of the adult Spanish general population included in the National Health Survey according to its smoking status. Data were included from National Health Survey for the year 2011-2012 with information of HRQoL status in general population over 15 years of age. Adult male and female, 18 years of age or above, were categorized into 3 exclusive groups according to their current smoking status: smokers (daily smokers of any form of tobacco, at least the previous 12 months), ex-smokers of one or more years since quitting smoking and people who have never smoked (non smokers). HRQoL was assessed with the Spanish version of the EQ-5D-5L questionnaire included into the National Health Survey. A total of 19,604 records were analyzed: 4,723 (24.09%) smokers, 3,797 (19.37%) ex-smokers, and 11,084 (56.54%) non smokers, male and female with 18 years of age or above. Smokers showed significantly adjusted mean scores (95% CI) in utility of 0.903 (0.899-0.908) and 75.36 (74.06-76.69) in the visual analogue scale of current state of health, ex-smokers 0.924 (0.919-0.929) and 76.85 (76.67-78.07), and non smokers 0.902 (0.899-0.905) and 76.25 (75.02-77.51), P<.01 between groups in both variables. In the Spanish general population, subjects who are ex-smokers showed better utility values and state health scores, supporting the hypothesis that quitting smoking could be associated with a discreet improvement of HRQoL.

  20. Remarkable selective constraints on exonic dinucleotide repeats.

    2014-09-01

    Long dinucleotide repeats found in exons present a substantial mutational hazard: mutations at these loci occur often and generate frameshifts. Here, we provide clear and compelling evidence that exonic dinucleotides experience strong selective constraint. In humans, only 18 exonic dinucleotides have repeat lengths greater than six, which contrasts sharply with the genome-wide distribution of dinucleotides. We genotyped each of these dinucleotides in 200 humans from eight 1000 Genomes Project populations and found a near-absence of polymorphism. More remarkably, divergence data demonstrate that repeat lengths have been conserved across the primate phylogeny in spite of what is likely considerable mutational pressure. Coalescent simulations show that even a very low mutation rate at these loci fails to explain the anomalous patterns of polymorphism and divergence. Our data support two related selective constraints on the evolution of exonic dinucleotides: a short-term intolerance for any change to repeat length and a long-term prevention of increases to repeat length. In general, our results implicate purifying selection as the force that eliminates new, deleterious mutants at exonic dinucleotides. We briefly discuss the evolution of the longest exonic dinucleotide in the human genome--a 10 x CA repeat in fibroblast growth factor receptor-like 1 (FGFRL1)--that should possess a considerably greater mutation rate than any other exonic dinucleotide and therefore generate a large number of deleterious variants. © 2014 The Author(s).

    Full Text Available To measure the views of general practitioners (GPs and rheumatologists in a nationwide evaluation, so as to optimise their cooperation in managing patients with inflammatory rheumatic diseases.A questionnaire covering aspects of collaboration was sent, both by mail and/or by email, to all GPs and rheumatologists in Austria. Topics covered were (i examinations and interventions to be performed before referral, (ii the spectrum of diseases to be referred, and (iii the role of GPs in follow-up and continuous management of patients.1,229 GPs of the 4,016 GPs (31% and 110 of the 180 rheumatologists (61% responded to the questionnaire. In cases of suspected arthritis, 99% of the GPs and 92% of the rheumatologists recommended specific laboratory tests, and 92% and 70%, respectively, recommended X-rays of affected joints before referral. Rheumatoid arthritis and spondyloarthritis, psoriatic arthritis and connective tissue disease were unanimously seen as indications for referral to a rheumatologist. Only 12% of rheumatologists felt responsible for the treatment of hand osteoarthritis and fibromyalgia. 80% of GPs and 85% of rheumatologists were of the opinion that treatment with disease-modifying drugs should be initiated by a specialist. Subsequent drug prescription and administration by GPs was supported by a majority of GPs and rheumatologists, with a concomitant rheumatologist follow-up every three to six months.The considerable consensus between the two professional groups constitutes a solid base for future joint recommendations, with the aim to accelerate the diagnostic process and the initiation of adequate therapy.

    Due to the variety of requirements across aerospace platforms, and one off projects, the repeatability of cryogenic multilayer insulation has never been fully established. The objective of this test program is to provide a more basic understanding of the thermal performance repeatability of MLI systems that are applicable to large scale tanks. There are several different types of repeatability that can be accounted for: these include repeatability between multiple identical blankets, repeatability of installation of the same blanket, and repeatability of a test apparatus. The focus of the work in this report is on the first two types of repeatability. Statistically, repeatability can mean many different things. In simplest form, it refers to the range of performance that a population exhibits and the average of the population. However, as more and more identical components are made (i.e. the population of concern grows), the simple range morphs into a standard deviation from an average performance. Initial repeatability testing on MLI blankets has been completed at Florida State University. Repeatability of five GRC provided coupons with 25 layers was shown to be +/- 8.4 whereas repeatability of repeatedly installing a single coupon was shown to be +/- 8.0. A second group of 10 coupons have been fabricated by Yetispace and tested by Florida State University, through the first 4 tests, the repeatability has been shown to be +/- 16. Based on detailed statistical analysis, the data has been shown to be statistically significant.

    Concerns have been raised that the DSM-IV requirements of six-month duration, excessive worry, and three associated symptoms exclude a substantial number of people with clinically significant anxiety from a diagnosis of generalized anxiety disorder (GAD). We examined the implications of relaxing these three criteria for the estimated prevalence and predictive validity of GAD using nationally representative data from the US National Comorbidity Survey Replication. Relaxing all three criteria more than doubles the estimated prevalence of GAD. Broadly-defined GAD significantly predicts the subsequent first onset of a wide range of temporally secondary disorders. The odds of secondary disorders are somewhat smaller for broadly-defined than DSM-IV GAD, though few of these differences are statistically significant. Results suggest that subthreshold manifestations of GAD are significantly related to elevated risk of subsequent psychopathology. Further research is needed to determine whether broadening the current diagnostic criteria results in a more valid characterization of GAD. PMID:17118626

    Many studies have demonstrated that the children of divorce are disproportionately likely to end their own marriages. In previous work, I showed that the transmission of divorce between generations weakened substantially for General Social Survey (GSS) respondents interviewed between 1973 and 1996 (Wolfinger 1999); Li and Wu (2006, 2008) contended that my finding is a methodological artifact of the GSS's lack of marriage duration data. This article presents a completed-cohort approach to studying divorce using the GSS. The results confirm a decline in the probability of divorce transmission that cannot be explained by the right-censoring bias alleged by Li and Wu. This finding contributes to an ongoing debate about trends in the negative consequences of parental divorce, as well as demonstrating a useful approach to right-censored phenomena when event history data are not available.

    The DSM approach to personality disorder (PD) diagnoses has been criticized for using arbitrary thresholds. The present study evaluated one dimensional approach with ordered threshold categories of severity by examining associations with several measures of disability and Axis I disorders for 10 PDs in the general population. Data were obtained from the National Epidemiologic Survey of Alcohol and Related Conditions, Waves 1 and 2. Respondents were categorized according to PD criteria as follows: "no symptoms" for having no positive criteria, "subthreshold" for having at least one positive criterion but below the DSM-IV threshold, "at-threshold" for meeting the DSM-IV threshold and additionally having one or two more positive criteria, and "suprathreshold" for meeting the DSM-IV threshold plus three or more positive criteria. Findings from this national study provide support for dimensional approaches to diagnostic classifications for the majority of PDs and suggest that mild levels of severity indeed have clinical significance.

    Background Ethnic minorities and some other patient groups consistently report lower scores on patient surveys, but the reasons for this are unclear. This study examined whether low scores of ethnic minority and other socio-demographic groups reflect their concentration in poorly performing primary care practices, and whether any remaining differences are consistent across practices. Methods Using data from the 2009 English General Practice Patient Survey (2 163 456 respondents from 8267 general practices) this study examined associations between patient socio-demographic characteristics and 11 measures of patient-reported experience. Findings South Asian and Chinese patients, younger patients, and those in poor health reported a less positive primary care experience than White patients, older patients and those in better health. For doctor communication, about half of the overall difference associated with South Asian patients (ranging from −6 to −9 percentage points) could be explained by their concentration in practices with low scores, but the other half arose because they reported less positive experiences than White patients in the same practices. Practices varied considerably in the direction and extent of ethnic differences. In some practices ethnic minority patients reported better experience than White patients. Differences associated with gender, Black ethnicity and deprivation were small and inconsistent. Conclusion Substantial ethnic differences in patient experience exist in a national healthcare system providing universal coverage. Improving the experience of patients in low-scoring practices would not only improve the quality of care provided to their White patients but it would also substantially reduce ethnic group differences in patient experience. There were large variations in the experiences reported by ethnic minority patients in different practices: practices with high patient experience scores from ethnic minority patients could be

    2011-12-01

    Full Text Available Over the last decade, there has been a marked increase in the number of studies on attitude and decision research which use the factorial survey (FS design. The FS integrates experimental set-ups into a survey: respondents react to hypothetical descriptions (vignettes while the values of each attribute (dimension of these descriptions systematically vary in order to estimate their impact on respondent judgments. As the vignettes are based on a number of dimensions and as respondents evaluate several vignettes, FSs are demanding in terms of individual cognitive and information-processing abilities. So far, there is little empirical knowledge of whether and to what extent this complexity is feasible in general population samples with heterogeneous respondents. Using data from a study on the fairness of earnings (with a mixed mode sample consisting a computer assisted personal interview [CAPI], computer assisted self interview [CASI], and paper and pencil [PAPI] mode, the complexity of FSs is analyzed in terms of: 1 design dimensions, such as the number of vignette dimensions (five, eight, or 12 and the number of vignettes for single respondents (10, 20, or 30, which were varied in a 3x3 experimental design; and 2 respondent characteristics that are associated with cognitive abilities (age and education. Two different indicators for cognitive load as well as learning and fatigue effects are analyzed: 1 latency time and 2 response consistency. The results show that raw reaction times but not latency times are longer for older respondents, suggesting that the cognitive effort needed for the evaluation of vignettes is not particularly high. Consistency measures reveal that respondents with a lower educational level show greater inconsistency in their evaluations when the number of vignettes is high. The number of dimensions has an effect on consistency only when respondents have to rate a large number of vignettes. In short, the results demonstrate

Taking into account that rugged relief may strongly disturb observed geophysical anomalies, the corresponding correction for non-flat relief influenced is of high importance. In essence, there are only two types of general analytical expressions applicable to the description of these geophysical fields (Alexeyev et al., 1996; Khesin et al., 1996; Eppelbaum, 2000). They are ∫ (zs --z)cosγp +-(xs --x)sinγp U1(x,z) = P r2 dxsdzs, S (1) [ ] ∫ (zs - z)2 - (xs - x)2 cosγp + 2(xs - x)(zs - z)sin γp U2(x,z) = P ------------4-----------dxsdzs, S r (2) where γp = 90o -ϕp,ϕp is the inclination angle of the polarization vector to the horizon, P is value of this vector (being a scalar in a particular case); S is the cross-section area of the body; P is the polarization vector (dipole moment of a unit volume); r = ° ---2-----2- (xs - x) + (zs - z)is the distance from the observation point M(x, z) to a certain point of the body P(xs,zs) Therefore, it seems sufficient to illustrate the manipulations taking as examples Eqs.

    Full Text Available Growing evidence indicates that self-reported height and weight are biased, but little is known about systematic errors in the general adult population in Japan. This study takes advantage of the unique opportunity to examine this issue provided by the 1986 National Nutrition Survey.Individual-level data on a nationally representative sample aged 20-89 years from the National Nutrition Survey (November 1986 were merged with Comprehensive Survey of Living Conditions (September 1986 data to obtain a dataset containing both self-reported and measured data on height and weight for each person (n = 10,469. Discrepancies between self-reported and measured means of height, weight, and body mass index (BMI were tested across measured BMI categories (<18.5, 18.5-24.9, 25.0-27.4, 27.5-29.9, and ≥30.0 kg/m2, age groups (20-44, 45-64, and 65-89 years, and sexes. Reporting bias in mean BMI was decomposed into the contributions of misreporting height and weight. The sensitivity and specificity of self-reported BMI categories were estimated.Mean self-reported BMI was substantially underestimated in older women (P<0.001; Cohen's d, -0.4, and the major contributor to the bias was their over-reported height. Mean self-reported BMI was also considerably underestimated in both men and women who were overweight and obese (P<0.001; Cohen's d, -1.0 to -0.6, due mainly to their underreported weight. In contrast, mean self-reported BMI was considerably overestimated in underweight men (P<0.001; Cohen's d, 0.5, due largely to their over-reported weight. The sensitivity of self-reported BMI categories was particularly low for individuals who had a measured BMI of 27.5-29.9 kg/m2 (40.9% for men and 26.8% for women.Self-reported anthropometric data were not sufficiently accurate to assert the validity of their use in epidemiological studies on the general adult population in Japan in the late 1980s.

    Background Pyrethroid insecticides are the most commonly used residential insecticides in the United States. Objectives Our objective was to assess human exposure via biomonitoring to pyrethroid insecticides in a representative sample of the general U.S. population ≥ 6 years of age. Methods By using isotope-dilution high-performance liquid chromatography/electrospray chemical ionization/tandem mass spectrometry, we measured five urinary metabolites of pyrethroid insecticides in 5,046 samples collected as a part of the 1999–2002 National Health and Nutrition Examination Survey (NHANES). Univariate, multivariate, and Pearson correlation analyses were performed using SUDAAN and SAS software, incorporating the appropriate sample weights into the analyses. Multivariate analyses included age, sex, race/ethnicity, creatinine, fasting status, and urine collection time as covariates. Results We detected 3-phenoxybenzoic acid (3PBA), a metabolite common to many pyrethroid insecticides, in more than 70% of the samples. The least-squares geometric mean (LSGM) concentration (corrected for covariates) of 3PBA and the frequency of detection increased from 1999–2000 (0.292 ng/mL) to 2001–2002 (0.318 ng/mL) but not significantly. Non-Hispanic blacks had significantly higher LSGM 3PBA concentrations than did non-Hispanic whites and Mexican Americans in the 2001–2002 survey period and in the combined 4-year survey periods but not in the 1999–2000 survey period. Children had significantly higher LSGM concentrations of 3PBA than did adolescents in both NHANES periods and than adults in NHANES 1999–2000. Cis- and trans-(2,2-dichlorovinyl)-2,2-dimethylcyclopropane-1-carboxylic acid were highly correlated with each other and with 3PBA, suggesting that urinary 3PBA was derived primarily from exposure to permethrin, cypermethrin, or their degradates. Conclusions Pyrethroid insecticide exposure in the U.S. population is widespread, and the presence of its metabolites in the

    The leucine rich repeat (LRR) motif that participates in many biomolecular recognition events in cells was suggested as a general scaffold for producing artificial receptors. We describe here the design and first total chemical synthesis of small LRR proteins, and their structural analysis. When evaluating the tertiary structure as a function of different number of repeating units (1-3), we were able to find that the 3-repeats sequence, containing 90 amino acids, folds into the expected structure.

    Background and aims To estimate the prevalence of problem and pathological gambling, gender and age-group differences in gambling types, and comorbidities with other psychiatric disorders among the Thai general population. Methods Analysis was conducted on 4,727 participants of Thailand's 2013 National Mental Health Survey, a multistage stratified cluster survey, using the Composite International Diagnostic Interview. Diagnoses of problem and pathological gambling and other psychiatric disorders were based on the DSM-IV-TR criteria with the following additional criteria for gamblers: more than 10 lifetime gambling episodes and a single year loss of at least 365 USD from gambling. Results The estimated lifetime prevalence rates of pathological and problem gambling were 0.90% [95% confidence interval (CI): 0.51-1.29] and 1.14% (95% CI: 0.58-1.70), respectively. The most popular type of gambling was playing lotteries [69.5%, standard error (SE) = 1.9], the prevalence of which was significantly higher among females and older age groups. The most common psychiatric disorders seen among pathological gamblers were alcohol abuse (57.4%), nicotine dependence (49.5%), and any drug use disorder (16.2%). Pathological gambling was highly prevalent among those who ever experienced major depressive episodes (5.5%), any drug dependence (5.1%), and intermittent explosive disorder (4.8%). The association between pathological gambling was strongest with a history of major depressive episode [adjusted odds ratio (AOR) = 10.4, 95% CI: 2.80-38.4]. Conclusion The study confirms the recognition of gambling disorders as a public health concern in Thailand and suggests a need for culturally specific preventive measures for pathological gamblers and those with a history of substance use disorders or major depression.

    Full Text Available Abstract Background Scientifically rigorous general population-based studies comparing chiropractic with primary-care medical patients within and between countries have not been published. The objective of this study is to compare care seekers of doctors of chiropractic (DCs and general practitioners (GPs in the United States and Canada on a comprehensive set of sociodemographic, quality of life, and health-related variables. Methods Data are from the Joint Canada/U.S. Survey of Health (JCUSH, 2002–03, a random sample of adults in Canada (N = 3505 and the U.S. (N = 5183. Respondents were categorized according to their pattern of health-care use in the past year. Distributions, percentages, and estimates (adjusted odds ratios weighted to reflect the complex survey design were produced. Results Nearly 80% of respondents sought care from GPs; 12% sought DC care. Compared with GP only patients, DC patients in both countries tend to be under 65 and white, with arthritis and disabling back or neck pain. U.S. DC patients are more likely than GP only patients to be obese and to lack a regular doctor; Canadian DC patients are more likely than GP only patients to be college educated, to have higher incomes, and dissatisfied with MD care. Compared with seekers of both GP and DC care, DC only patients in both countries have fewer chronic conditions, take fewer drugs, and have no regular doctor. U.S. DC only patients are more likely than GP+DC patients to be uninsured and dissatisfied with health care; Canadian DC only patients are more likely than GP+DC patients to be under 45, male, less educated, smokers, and not obese, without disabling back or neck pain, on fewer drugs, and lacking a regular doctor. Conclusion Chiropractic and GP patients are dissimilar in both Canada and the U.S., with key differences between countries and between DC patients who do and do not seek care from GPs. Such variation has broad and potentially far-reaching health policy and

    Background Stigmatising and discriminating attitudes may discourage tuberculosis (TB) patients from actively seeking medical care, hide their disease status, and discontinue treatment. It is expected that appropriate knowledge regarding TB should remove stigmatising and discriminating attitudes. In this study we assessed the prevalence of stigmatising and discriminating attitudes towards TB patients among general population and their association with knowledge regarding TB. Method A cross-sectional knowledge, attitude and practice survey was conducted in 30 districts of India in January-March 2011. A total of 4562 respondents from general population were interviewed using semi-structured questionnaires which contained items to measure stigma, discrimination and knowledge on TB. Result Of the 4562 interviewed, 3823 were eligible for the current analysis. Of these, 73% (95% CI 71.4–74.2) had stigmatising and 98% (95% CI 97.4–98.3) had discriminating attitude towards TB patients. Only 17% (95% CI 15.6–18.0) of the respondents had appropriate knowledge regarding TB with even lower levels observed amongst females, rural areas and respondents from low income groups. Surprisingly stigmatising (adjusted OR 1.31 (0.78–2.18) and discriminating (adjusted OR 0.79 (0.43–1.44) attitudes were independent of knowledge regarding TB. Conclusion Stigmatising and discriminating attitudes towards TB patients remain high among the general population in India. Since these attitudes were independent of the knowledge regarding TB, it is possible that the current disseminated knowledge regarding TB which is mainly from a medical perspective may not be adequately addressing the factors that lead to stigma and discrimination towards TB patients. Therefore, there is an urgent need to review the messages and strategies currently used for disseminating knowledge regarding TB among general population and revise them appropriately. The disseminated knowledge should include medical

    The Seasonal Ice Zone of the Beaufort Sea is the area of ocean north of Alaska over which sea ice melts and reforms annually. It contains the more narrow, near-edge marginal ice zone (MIZ). Seasonal Ice Zone Reconnaissance Surveys (SIZRS) measure hydrography along two meridional sections using Air eXpendable CTDs (AXCTDs) and Air eXpendable Current Profilers (AXCPs). These surveys take place aboard U.S. Coast Guard Arctic Domain Awareness flights of opportunity during each melt season (June-October) starting in 2012. The Marginal Ice Zone Modeling and Assimilation System (MIZMAS) is a high-resolution regional ice-ocean model with daily, three-dimensional output encompassing the SIZRS survey area. Direct comparison of the SIZRS data with MIZMAS output as well as with several regional climatologies can constrain the ice-ocean model and help to explain recent changes in subsurface heat content and salinity. For example, observed freshening relative to climatology has been used as a reference to which MIZMAS surface salinity values can be relaxed. MIZMAS may in turn shed light on the physical mechanisms driving the observed freshening. In addition, use of MIZMAS surface fluxes to drive a one-dimensional mixed layer model gives results close to observations when the model is initialized with SIZRS profiles. Because SIZRS observations range in time from the onset of melt to the onset of Fall freeze-up, the comparison of the one-dimensional model with MIZMAS illustrates the relative roles of local and regional processes in forming near-surface temperature maxima and salinity minima. The SIZRS observations and one-dimensional model are used to constrain MIZMAS estimations of stored subsurface heat while establishing the physical drivers of these temperature and salinity changes.

    Full Text Available Abstract Background Missed appointments are a common occurrence in primary care in the UK, yet little is known about the reasons for them, or the consequences of missing an appointment. This paper aims to determine the reasons for missed appointments and whether patients who miss an appointment subsequently consult their general practitioner (GP. Secondary aims are to compare psychological morbidity, and the previous appointments with GPs between subjects and a comparison group. Methods Postal questionnaire survey and prospective medical notes review of adult patients missing an appointment and the comparison group who attended appointments over a three week period in seven general practices in West Yorkshire. Results Of the 386 who missed appointments 122 (32% responded. Of the 386 in the comparison group 223 (58% responded, resulting in 23 case-control matched pairs with complete data collection. Over 40% of individuals who missed an appointment and participated said that they forgot the appointment and a quarter said that they tried very hard to cancel the appointment or that it was at an inconvenient time. A fifth reported family commitments or being too ill to attend. Over 90% of the patients who missed an appointment subsequently consulted within three months and of these nearly 60% consulted for the stated problem that was going to be presented in the missed consultation. The odds of missing an appointment decreased with increasing age and were greater among those who had missed at least one appointment in the previous 12 months. However, estimates for comparisons between those who missed appointments and the comparison group were imprecise due to the low response rate. Conclusion Patients who miss appointments tend to cite practice factors and their own forgetfulness as the main reasons for doing so, and most attend within three months of a missed appointment. This study highlights a number of implications for future research. More work

    Full Text Available OBJECTIVE: To report geographical variations of sex-specific diabetes by place of residence (large cities/city corporations, small towns/other urban areas, rural areas and region of residence (divided into seven divisions among general adults (35+ years of age in Bangladesh. METHODS: The recent cross-sectional data, extracted from the nationally representative Bangladesh Demographic and Health Survey 2011, was used. A total of 3,720 men and 3,823 women aged 35+ years, who participated in the fasting blood sugar testing, were analysed. Any person with either fasting plasma glucose level (mmol/L ≥7.0 or taking medication for diabetes was considered as a person with diabetes. RESULTS: The prevalence of diabetes was 10.6% in men and 11.3% in women. Bivariable analyses indicated significant variations of diabetes by both geographical variables. The prevalence was highest in city corporations (men 18.0%, women 22.3%, followed by small towns (men 13.6%, women 15.2% and rural areas (men 9.3%, women 9.5%. Regional disparities in diabetes prevalence were also remarkable, with the highest prevalence in Chittagong division and lowest prevalence in Khulna division. Multivariable logistic regression analyses provided mixed patterns of geographical disparities (depending on the adjusted variables. Some other independent risk factors for diabetes were advancing age, higher level of education and wealth, having TV (a proxy indicator of physical activity, overweight/obesity and hypertension. CONCLUSIONS: Over 10% of the general adults aged 35 years and older were having diabetes. Most of the persons with diabetes were unaware of this before testing fasting plasma glucose level. Although significant disparities in diabetes prevalence by geographical variables were observed, such disparities are very much influenced by the adjusted variables. Finally, we underscore the necessities of area-specific strategies including early diagnosis and health education

  1. Expansion of protein domain repeats.

    2006-08-01

    Full Text Available Many proteins, especially in eukaryotes, contain tandem repeats of several domains from the same family. These repeats have a variety of binding properties and are involved in protein-protein interactions as well as binding to other ligands such as DNA and RNA. The rapid expansion of protein domain repeats is assumed to have evolved through internal tandem duplications. However, the exact mechanisms behind these tandem duplications are not well-understood. Here, we have studied the evolution, function, protein structure, gene structure, and phylogenetic distribution of domain repeats. For this purpose we have assigned Pfam-A domain families to 24 proteomes with more sensitive domain assignments in the repeat regions. These assignments confirmed previous findings that eukaryotes, and in particular vertebrates, contain a much higher fraction of proteins with repeats compared with prokaryotes. The internal sequence similarity in each protein revealed that the domain repeats are often expanded through duplications of several domains at a time, while the duplication of one domain is less common. Many of the repeats appear to have been duplicated in the middle of the repeat region. This is in strong contrast to the evolution of other proteins that mainly works through additions of single domains at either terminus. Further, we found that some domain families show distinct duplication patterns, e.g., nebulin domains have mainly been expanded with a unit of seven domains at a time, while duplications of other domain families involve varying numbers of domains. Finally, no common mechanism for the expansion of all repeats could be detected. We found that the duplication patterns show no dependence on the size of the domains. Further, repeat expansion in some families can possibly be explained by shuffling of exons. However, exon shuffling could not have created all repeats.

    Objective: To determine the prevalence and comorbid mental disorders of self-reported diagnosis of burnout syndrome in the general population of Germany. Methods: In the German Health Interview and Examination Survey (DEGS1) self-reported diagnosis of a burnout syndrome made by a physician or psychotherapist was assessed in a standardized interview (N = 7987). For N = 4483 mental disorders were determined with the Composite International Diagnostic Interview (CIDI). Weighted lifetime and 12-month prevalences were calculated. Results: Lifetime prevalence of diagnosed burnout syndrome was 4.2 % (women 5.2 %, men 3.3 %), 12-month prevalence was 1.5 % (women 1.9 %, men 1.1 %). Highest prevalences were found in 40 - 59 year olds, in people with middle and high socio-economic status and in women with low and men with high social support. Among the 12-month cases, 70.9 % had at least one DSM-IV disorder. Associations were found for the diagnosis of burnout syndrome with somatoform, affective and anxiety disorders. Conclusion: The diagnosis of burnout syndrome is less frequently given and reported than expected. People with a burnout diagnosis often have a manifest mental disorder. © Georg Thieme Verlag KG Stuttgart · New York.

    Introduction: We present data from the Korean National Health and Nutrition Examination Survey 2008-2009 on the distribution of blood cadmium levels and their association with iron deficiency in a representative sample of the adult Korean population. Methods: Serum ferritin was categorized into three levels: low (serum ferritin <15.0 {mu}g/L), low normal (15.0-30.0 {mu}g/L for women and 15.0-50.0 for men), and normal ({>=}30.0 {mu}g/L for women and {>=}50.0 for men), and its association with blood cadmium level was assessed after adjustment for various demographic and lifestyle factors. Results: Geometric means of blood cadmium in the low serum ferritin group in women, men, and all participants were significantly higher than in the normal group. Additionally, multiple regression analysis after adjusting for various covariates showed that blood cadmium was significantly higher in the low-ferritin group in women, men, and all participants compared with the normal group. We also found an association between serum ferritin and blood cadmium among never-smoking participants. Discussion: We found, similar to other recent population-based studies, an association between iron deficiency and increased blood cadmium in men and women, independent of smoking status. The results of the present study show that iron deficiency is associated with increased levels of blood cadmium in the general population.

    Obesity is a widespread national issue that affects the health and well-being of millions of people; particular attention has been focused on the burden among children. The National Survey of Children's Health data from 2007 was used to examine the relationship of child health status and unhealthy weight (overweight/obese defined as body mass index in ≥ 85 th percentile) among 874 children aged 10 to 17 years of age in Hawai'i. In particular, the parentally reported child's general health status was assessed comparing those with a poorer health status (defined as "good/fair/poor") to those with a better one (defined as "excellent/very good"). Descriptive analysis and multiple logistic regression analysis examined risk for overweight/obese with child's general health status, accounting for gender, race, and socioeconomic factors. More children with a poorer health status (46.5%; 95%CI=33.2-60.2) were overweight/obese compared to those of better health status (25.8%; 95%CI=21.9-30.2). Estimates of overweight/obese were high in Native Hawaiian/Pacific Islander (38.6%; 95%CI: 28.9-49.4), multiracial (30.9%; 95%CI=24.2-38.6) children, and children whose parents had less than 12 years education (56.8%; 95%CI=32.8-78.0). Multivariate logistic regression modeling showed a 2.92 (95%CI=1.52-5.61) greater odds for overweight/obese status in children with a poorer health status compared to those of better health status after accounting for age, race, gender, and parental education. Gender, race, and parental education were also significant factors associated with overweight/obese in the final adjusted model. It is important that children that are overweight or obese receive appropriate health screenings including assessments of general health status. Children in high risk socioeconomic groups should be a particular focus of prevention efforts to promote health equity and provide opportunities for children to reach their potential.

  8. Genus-specific protein binding to the large clusters of DNA repeats (short regularly spaced repeats) present in Sulfolobus genomes

    Short regularly spaced repeats (SRSRs) occur in multiple large clusters in archaeal chromosomes and as smaller clusters in some archaeal conjugative plasmids and bacterial chromosomes. The sequence, size, and spacing of the repeats are generally constant within a cluster but vary between clusters...... that are identical in sequence to one of the repeat variants in the S. solfataricus chromosome. Repeats from the pNOB8 cluster were amplified and tested for protein binding with cell extracts from S. solfataricus. A 17.5-kDa SRSR-binding protein was purified from the cell extracts and sequenced. The protein is N...... terminally modified and corresponds to SSO454, an open reading frame of previously unassigned function. It binds specifically to DNA fragments carrying double and single repeat sequences, binding on one side of the repeat structure, and producing an opening of the opposite side of the DNA structure. It also...

    Full Text Available Abstract Background Sexual abstinence is the best available option for preventing both pregnancy and sexually transmitted infections, including HIV/AIDS. Identifying the factors associated with sexual abstinence among youths would have meaningful implications in a generalized HIV epidemic country such as the Côte d'Ivoire. Thus, we explored sexual abstinence behavior among never-married individuals aged 15 to 24 in Côte d'Ivoire and assessed factors that predict sexual abstinence. Methods We obtained data from the nationally representative and population-based 2005 Côte d'Ivoire AIDS Indicator Survey, conducted from September 2004 to October 2005. Our sample included 3041 never-married people aged 15 to 24. Of these, 990 reported never having sexual intercourse (primary abstinence and 137 reported sexual experience but not in the 12 months prior to the survey (secondary abstinence. In all, 1127 youths reported sexual abstinence practice. Results Of the 3041 never-married youths, 54.4% were male and 45.6% were female. About 33.0%, 6.7%, and 37.1% of them were practicing primary, secondary, and sexual abstinence behavior, respectively. Females of higher education level were significantly 11.14 times as likely as those of no education to practice either primary or secondary abstinence. Males who were animists, had no religion, or were practicing religions other than Christianity or Muslim were significantly less likely than other male youths to practice sexual abstinence (OR = 0.53, 95% CI = 0.30–0.95. Living in the north-west region of the country significantly decreased the odds of sexual abstinence among female youths. Similarly, female youths living in rural areas were significantly 0.42 times as likely as those in the urban zones to practice sexual abstinence. Conclusion HIV/AIDS prevention program components could include media campaigns, educational intervention improvement, as well as promoting policies that shape female youth

    When and whence does wood enter large mountain alluvial rivers? How stable through time are characteristics and quantities of wood deposited in a reach? These simple questions related to the complex practice of wood budgeting are explored on the Isère River in France. We hypothesise that (i) the wood originates from the riparian zone all along the alluvial reach and that (ii) the characters and quantity of wood in the reach can vary through time according to flood occurrence and provenance. In order to validate these hypotheses, two complementary approaches were performed: (i) wood pieces were surveyed along 190 km river length and taxonomy, in-channel wood macromorphology, and dendrochemistry were used to infer wood origin (local vs. upstream, respective subbasin contributions) and transport conditions; (ii) wood movement was monitored using both tracking techniques in specific sampling plots and with an experiment orchestrated using wood placement coupled with a significant artificial flood. Surveys were done over a period of 3 years so as to include two distinct sampling events to explore wood deposition and mobilisation within a channel network under different flood conditions. One of the subbasins, the Arly River, underwent a 1-in-30-year flood in 2004, allowing us to assess its effect on in-channel wood quantity and characteristics. Results confirm that wood is primarily introduced by erosion from river banks but they are not always as close as expected from the sites of deposition. Temporal variability of wood introduced, deposited, and transferred downstream is also significant in terms of abundance and origin as shown by dendrochemical and macromorphological signatures. The types of wood observed along the channel length changes through time. Large flood signature can be detected from wood characteristics and uplands make a slight contribution. But in average, wood characteristics do not change much (no significant difference between years and tributaries

  11. All-photonic quantum repeaters

    Quantum communication holds promise for unconditionally secure transmission of secret messages and faithful transfer of unknown quantum states. Photons appear to be the medium of choice for quantum communication. Owing to photon losses, robust quantum communication over long lossy channels requires quantum repeaters. It is widely believed that a necessary and highly demanding requirement for quantum repeaters is the existence of matter quantum memories. Here we show that such a requirement is, in fact, unnecessary by introducing the concept of all-photonic quantum repeaters based on flying qubits. In particular, we present a protocol based on photonic cluster-state machine guns and a loss-tolerant measurement equipped with local high-speed active feedforwards. We show that, with such all-photonic quantum repeaters, the communication efficiency scales polynomially with the channel distance. Our result paves a new route towards quantum repeaters with efficient single-photon sources rather than matter quantum memories. PMID:25873153

    Full Text Available Marine fishing communities are among the most marginalised and hard-to-reach groups and have been largely neglected in health research. We examined the quality of cataract surgery and its determinants, with an emphasis on gender, in marine fishing communities in Karachi, Pakistan, using multiple indicators of performance.The Karachi Marine Fishing Communities Eye and General Health Survey was a door-to-door, cross-sectional study conducted between March 2009 and April 2010 in fishing communities living on 7 islands and in coastal areas in Keamari, Karachi, located on the Arabian Sea. A population-based sample of 638 adults, aged ≥ 50 years, was studied. A total of 145 eyes (of 97 persons had undergone cataract surgery in this sample. Cataract surgical outcomes assessed included vision (presenting and best-corrected with a reduced logMAR chart, satisfaction with surgery, astigmatism, and pupil shape. Overall, 65.5% of the operated eyes had some form of visual loss (presenting visual acuity [PVA] < 6/12. 55.2%, 29.0%, and 15.9% of these had good, borderline, and poor visual outcomes based on presenting vision; with best correction, these values were: 68.3 %, 18.6%, and 13.1%, respectively. Of 7 covariates evaluated in the multivariable generalized estimating equations (GEE analyses, gender was the only significant independent predictor of visual outcome. Women's eyes were nearly 4.38 times more likely to have suboptimal visual outcome (PVA<6/18 compared with men's eyes (adjusted odds ratio 4.38, 95% CI 1.96-9.79; P<0.001 after adjusting for the effect of household financial status. A higher proportion of women's than men's eyes had an irregular pupil (26.5% vs. 14.8% or severe/very severe astigmatism (27.5% vs. 18.2%. However, these differences did not reach statistical significance. Overall, more than one fourth (44/144 of cataract surgeries resulted in dissatisfaction. The only significant predictor of satisfaction was visual outcome (P <0

    Full Text Available The aim of the survey was to introduce knowledge of HPV's role in head and neck pathologies to general physicians (GPs, otorhinolaryngologists (ENTs and newly graduated doctors, as well as to promote HPV-related diseases prevention.Cross-sectional study.Self-designed questionnaire was sent to 2100 doctors. A total of 404 doctors, including 144 ENTs, 192 GPs and 68 trainees, responded.The majority of ENTs (86.8% had contact with recurrent respiratory papillomatosis (RRP and oropharyngeal cancers (OPCs patients; in contrast, the majority of GPs (55.7% did not (p = 0.00. The knowledge of HPV aetiology of cervical cancer versus OPCs and RRP was statistically higher. 7% of ENTs, 20% of GPs and 10% of trainees had not heard about HPV in oropharyngeal diseases. Women had greater knowledge than men. Both in the group of GPs and ENTs, 100% of respondents had heard about the impact of vaccination on the reduction of cervical cancer incidence. Only 39.11% of respondents had heard about the possibility of using vaccination against HPV in RRP-ENT doctors significantly more often than GPs and trainees (p = 0.00. Only 28.96% of physicians had heard about the potential value of HPV vaccination in preventing OPCs, including 44.44% of ENT doctors, 23.44% of GPs and 11.76% of trainees (p = 0.00. The doctors from district hospitals showed lower level of knowledge compared with clinicians (p = 0.04.The different levels of knowledge and awareness of HPV issues highlight the need for targeted awareness strategies in Poland with implementation of HPV testing and vaccination. The information should be accessible especially to those with lower education levels: ENTs from small, provincial wards, GPs from cities of < 200,000 inhabitants and older physicians. The incorporation of HPV issues into the studies curriculum would be fruitful in terms of improving the knowledge of trainees.

    Although chronic cough is very common, its prevalence and causes have been rarely reported in the large general population including smokers. This study aimed to identify the prevalence of possible causes of chronic cough and their clinical impact.From Korean National Health and Nutrition Examination Survey (KNHANES) data including 119,280 adults aged over 40 years, 302 individuals with chronic cough were recruited irrespective of smoking status. Data from questionnaire, laboratory tests including spirometry, chest radiographs, and otorhinolaryngologic examination were analyzed.The prevalence of chronic cough in adults was 2.5% ± 0.2%. Current smokers occupied 47.7% ± 3.8% of study population and 46.8% ± 3.9% of the subjects showed upper airway cough syndrome (UACS). Based on spirometry, chronic obstructive pulmonary disease (COPD) was identified in 26.4% ± 3.5%. Asthma explained for 14.5% ± 2.8% of chronic cough. Only 4.1% ± 1.6% showed chronic laryngitis suggesting gastro-esophageal reflux-related cough. Abnormalities on chest radiography were found in 4.0% ± 1.2%. Interestingly, 50.3% ± 4.5% of study subjects had coexisting causes. In multivariate analysis, only current smoking (odds ratio [OR] 3.16, P cough. This pattern was not different according to smoking status excepting the prevalence of COPD.Smoking, COPD, and chest radiographic abnormalities should be considered as causes of chronic cough, along with UACS and asthma. Gastro-esophageal reflux-related cough is not prevalent in study population.

    Full Text Available Abstract Background In order to proceed from a paper based registration to a surveillance system that is based on extraction of electronic health records (EHR, knowledge is needed on the number and representativeness of sentinel GPs using a government-certified EHR system and the quality of EHR data for research, expressed in the compliance rate with three criteria: recording of home visits, use of prescription module and diagnostic subject headings. Methods Data were collected by annual postal surveys between 2005 and 2009 among all sentinel GPs. We tested relations between four key GP characteristics (age, gender, language community, practice organisation and use of a certified EHR system by multivariable logistic regression. The relation between EHR software package, GP characteristics and compliance with three quality criteria was equally measured by multivariable logistic regression. Results A response rate of 99% was obtained. Of 221 sentinel GPs, 55% participated in the surveillance without interruption from 2005 onwards, i.e. all five years, and 78% were participants in 2009. Sixteen certified EHR systems were used among 91% of the Dutch and 63% of the French speaking sentinel GPs. The EHR software package was strongly related to the community and only one EHR system was used by a comparable number of sentinel GPs in both communities. Overall, the prescription module was always used and home visits were usually recorded. Uniform subject headings were only sometimes used and the compliance with this quality criterion was almost exclusively related to the EHR software package in use. Conclusions The challenge is to progress towards a sentinel network of GPs delivering care-based data that are (partly extracted from well performing EHR systems and still representative for Belgian general practice.

    Full Text Available Abstract Background There has been an overall decrease in incident ischaemic heart disease (IHD, but the reduction in IHD risk factors has been greater among those with higher social position. Increased social inequalities in IHD mortality in Scandinavian countries is often referred to as the Scandinavian “public health puzzle”. The objective of this study was to examine trends in absolute and relative educational inequalities in four modifiable ischaemic heart disease risk factors (smoking, diabetes, hypertension and high total cholesterol over the last three decades among Norwegian middle-aged women and men. Methods Population-based, cross-sectional data from The Nord-Trøndelag Health Study (HUNT: HUNT 1 (1984–1986, HUNT 2 (1995–1997 and HUNT 3 (2006–2008, women and men 40–59 years old. Educational inequalities were assessed using the Slope Index of Inequality (SII and The Relative Index of Inequality (RII. Results Smoking prevalence increased for all education groups among women and decreased in men. Relative and absolute educational inequalities in smoking widened in both genders, with significantly higher absolute inequalities among women than men in the two last surveys. Diabetes prevalence increased in all groups. Relative inequalities in diabetes were stable, while absolute inequalities increased both among women (p = 0.05 and among men (p = 0.01. Hypertension prevalence decreased in all groups. Relative inequalities in hypertension widened over time in both genders. However, absolute inequalities in hypertension decreased among women (p = 0.05 and were stable among men (p = 0.33. For high total cholesterol relative and absolute inequalities remained stable in both genders. Conclusion Widening absolute educational inequalities in smoking and diabetes over the last three decades gives rise to concern. The mechanisms behind these results are less clear, and future studies are needed to assess if educational

    Full Text Available Abstract Background General practitioners (GPs are ideally placed to bridge the widely noted evidence-practice gap between current management of NVAF and the need to increase anticoagulant use to reduce the risk of fatal and disabling stroke in NVAF. We aimed to identify gaps in current care, and asked GPs to identify potentially useful strategies to overcome barriers to best practice. Methods We obtained contact details for a random sample of 1000 GPs from a national commercial data-base. Randomly selected GPs were mailed a questionnaire after an advance letter. Standardised reminders were administered to enhance response rates. As part of a larger survey assessing GP management of NVAF, we included questions to explore GPs' risk assessment, estimates of stroke risk and GPs' perceptions of the risks and benefits of anticoagulation with warfarin. In addition, we explored GPs' perceived barriers to the wider uptake of anticoagulation, quality control of anticoagulation and their assessment of strategies to assist in managing NVAF. Results 596 out of 924 eligible GPs responded (64.4% response rate. The majority of GPs recognised that the benefits of warfarin outweighed the risks for three case scenarios in which warfarin is recommended according to Australian guidelines. In response to a hypothetical case scenario describing a patient with a supratherapeutic INR level of 5, 41.4% of the 596 GPs (n = 247 and 22.0% (n = 131 would be "highly likely" or "likely", respectively, to cease warfarin therapy and resume at a lower dose when INR levels are within therapeutic range. Only 27.9% (n = 166/596 would reassess the patient's INR levels within one day of recording the supratherapeutic INR. Patient contraindications to warfarin was reported to "usually" or "always" apply to the patients of 40.6% (n = 242/596 of GPs when considering whether or not to prescribe warfarin.

    Full Text Available Background: Prompt treatment affects prognosis and survival after acute myocardial infarction (AMI onset. This study evaluated the awareness of early symptoms of AMI and knowledge of appropriate responses on symptom occurrence, along with related factors. Methods: Participants’ knowledge of the early symptoms of and responses to AMI onset were investigated using a random digit dialing survey. We included 9600 residents of 16 metropolitan cities and provinces in Korea. Results: The proportions of respondents who were aware of early symptoms of AMI ranged from 32.9% (arm or shoulder pain to 79.1% (chest pain and discomfort. Of the respondents, 67.0% would call an ambulance if someone showed signs of AMI, 88.7% knew ≥1 symptom, 10.9% knew all five symptoms, and 3.1% had excellent knowledge (correct identification of all five AMI symptoms, not answering “Yes” to the trap question, and correctly identifying calling an ambulance as the appropriate response when someone is exhibiting AMI symptoms. The odds ratio (OR for having excellent knowledge was significantly higher for those who graduated college or higher (OR 3.42; 95% confidence interval [CI], 1.09–10.76 than for those with less than a primary school education, as well as for subjects with AMI advertisement exposure (OR 1.49; 95% CI, 1.10–2.02 and with knowledge of AMI (OR 1.63; 95% CI, 1.16–2.27. The 60- to 79-year-old group had significantly lower OR for excellent knowledge than the 20- to 39-year-old group (OR 0.53; 95% CI, 0.28–0.99. Conclusions: Awareness of AMI symptoms and the appropriate action to take after symptom onset in South Korea was poor. Therefore, educational and promotional strategies to increase the overall awareness in the general public, especially in the elderly and those with low education levels, are needed.

    BACKGROUND: Very little is known about the prevalence of acquired brain injury (ABI) in Ireland. ABI prevalence has previously been obtained from Belgian general practitioners using a postal survey. We attempted to ascertain the prevalence of ABI in County Mayo through a postal survey of all general practitioners in the county.The specific objectives of this project were to:1. identify whether general practitioners are a. aware of patients with ABI aged 18-65 in their practices b. able to provide prevalence data on ABI in patients aged 18-65 c. able to provide data on age, gender and patient diagnosis 2. analyse prevalence of ABI from any available data from general practitioners. METHODS: A pilot postal survey was performed initially in order to assess the feasibility of the study. It was established that general practitioners did have the necessary information required to complete the questionnaire. A main postal survey was then undertaken. A postal questionnaire was administered to all general practices in County Mayo in the west of Ireland (n = 59). The response rate was 32.2% (n = 19). RESULTS: General practitioners who replied on behalf of their practice could provide data on patient age, gender and diagnosis. In the nineteen practices, there were 57 patients with ABI. The age-specific prevalence of ABI in the area surveyed was estimated at 183.7 per 100,000. The mean patient population per practice was 2,833 (SD = 950). There were found to be significantly more patients with ABI in rural areas than urban areas (p = 0.006). There were also significant differences in the ages of patients in the different ABI categories. Patients whose ABI was of traumatic origin were significantly younger than those patients with ABI of haemorrhagic origin (p = 0.002). CONCLUSION: Although this is a small-scale study, we have ascertained that general practitioners do have data on patients with ABI. Also, some prevalence data now exist where none was available before. These can

    In 1971, a comprehensive ecological survey of the native pinewoods of Scotland was carried out by the Institute of Terrestrial Ecology. The survey was initiated as a consequence of growing concern about the status of the pinewood resource. Since the twentieth century, this unique habitat is widely recognised, not only by ecologists for its inherent biodiversity but also by the general public for its cultural and amenity value. The survey, utilising demonstrably repeatable methods, collected information on ground flora, soils, forest structure and also general site information from the major 27 sites of the 35 sites identified as truly native pinewoods in Scotland. The results from the survey prompted the organisation of an international symposium in 1975, which set the conservation agenda for the old Caledonian pinewoods. The data collected during the 1971 survey are now publicly available via the following DOI: doi:10/7xb ("Habitat, vegetation, tree and soil data from Native Pinewoods in Scotland, 1971"). Although the data are now 44 years old, the repeatable methods will allow for a resurvey to take place, in order to assess changes in the vegetation, habitats and tree composition in a statistically robust manner.

    The Gd{sub 5}Ge{sub 2}Si{sub 2} alloy and the off-stoichiometric Ni{sub 50}Mn{sub 35}In{sub 15} Heusler alloy belong to a special class of metallic materials that exhibit first-order magnetostructural transitions near room temperature. The magnetic properties of this class of materials have been extensively studied due to their interesting magnetic behavior and their potential for a number of technological applications such as refrigerants for near-room-temperature magnetic refrigeration. The thermally driven first-order transitions in these materials can be field-induced in the reverse order by applying a strong enough field. The field-induced transitions are typically accompanied by the presence of large magnetic hysteresis, the characteristics of which are a complicated function of temperature, field, and magneto-thermal history. In this study we show that the virgin curve, the major loop, and sequentially measured MH loops are the results of both repeatable and non-repeatable processes, in which the starting magnetostructural state, prior to the cycling of field, plays a major role. Using the Gd{sub 5}Ge{sub 2}Si{sub 2} and Ni{sub 50}Mn{sub 35}In{sub 15} alloys, as model materials, we show that a starting single phase state results in fully repeatable processes and large magnetic hysteresis, whereas a mixed phase starting state results in non-repeatable processes and smaller hysteresis.

    To explore public knowledge of, and interest in, learning more about medicines R&D in six European countries. Online survey of 6931 members of the public across Europe. The survey formed part of a public omnibus survey. A quota sampling approach was used with quotas set according to national census data on age, gender and government region. The survey explored the public's knowledge and awareness of medicines R&D, their interest in learning more and the perceived influences on this. The survey was completed by 6931 members of the public, over 75% of whom reported having no or less than good knowledge of medicines R&D. Males were more likely than females to report good knowledge (17% vs 15%), and knowledge appeared to decrease with age. Those who were currently or had previously been involved in medical research were almost five times more likely to report good knowledge of medicines R&D overall (43% vs 13%). Participants reported good knowledge of medicines safety and clinical trials but little knowledge of pharmacoeconomics. They were most interested in learning more about medicines safety and personalised and predictive medicine and least interested in pharmacoeconomics. Older people, women and respondents with current good knowledge of medicines R&D were most interested in learning more about medicines R&D. Experience of medical research appears to play a key role in increasing public awareness of and future interest in medicines R&D. Some groups may need to be specifically targeted to increase their awareness of medicines R&D, for example, women expressed great interest in learning more but reported less knowledge than men. It may be useful to explore further the views of those who are currently uninterested in learning more. Published by the BMJ Publishing Group Limited.

    Comparative population genetic analyses of traditional and emergent molecular markers aid in determining appropriate use of new technologies. The bocaccio rockfish Sebastes paucispinis is a high gene-flow marine species off the west coast of North America that experienced strong population decline over the past 3 decades. We used 18 anonymous and 13 gene-associated simple sequence repeat (SSR) loci (expressed sequence tag [EST]-SSRs) to characterize range-wide population structure with temporal replicates. No F(ST)-outliers were detected using the LOSITAN program, suggesting that neither balancing nor divergent selection affected the loci surveyed. Consistent hierarchical structuring of populations by geography or year class was not detected regardless of marker class. The EST-SSRs were less variable than the anonymous SSRs, but no correlation between F(ST) and variation or marker class was observed. General linear model analysis showed that low EST-SSR variation was attributable to low mean repeat number. Comparative genomic analysis with Gasterosteus aculeatus, Takifugu rubripes, and Oryzias latipes showed consistently lower repeat number in EST-SSRs than SSR loci that were not in ESTs. Purifying selection likely imposed functional constraints on EST-SSRs resulting in low repeat numbers that affected diversity estimates but did not affect the observed pattern of population structure.

    Full Text Available Abstract Background Research into risk perception and behavioural responses in case of emerging infectious diseases is still relatively new. The aim of this study was to examine perceptions and behaviours of the general public during the early phase of the Influenza A (H1N1 pandemic in the Netherlands. Methods Two cross-sectional and one follow-up online survey (survey 1, 30 April-4 May; survey 2, 15-19 June; survey 3, 11-20 August 2009. Adults aged 18 years and above participating in a representative Internet panel were invited (survey 1, n = 456; survey 2, n = 478; follow-up survey 3, n = 934. Main outcome measures were 1 time trends in risk perception, feelings of anxiety, and behavioural responses (survey 1-3 and 2 factors associated with taking preventive measures and strong intention to comply with government-advised preventive measures in the future (survey 3. Results Between May and August 2009, the level of knowledge regarding Influenza A (H1N1 increased, while perceived severity of the new flu, perceived self-efficacy, and intention to comply with preventive measures decreased. The perceived reliability of information from the government decreased from May to August (62% versus 45%. Feelings of anxiety decreased from May to June, and remained stable afterwards. From June to August 2009, perceived vulnerability increased and more respondents took preventive measures (14% versus 38%. Taking preventive measures was associated with no children in the household, high anxiety, high self-efficacy, more agreement with statements on avoidance, and paying much attention to media information regarding Influenza A (H1N1. Having a strong intention to comply with government-advised preventive measures in the future was associated with higher age, high perceived severity, high anxiety, high perceived efficacy of measures, high self-efficacy, and finding governmental information to be reliable.

    The application of statistics in reported research in trauma and orthopaedic surgery has become ever more important and complex. Despite the extensive use of statistical analysis, it is still a subject which is often not conceptually well understood, resulting in clear methodological flaws and inadequate reporting in many papers. A detailed statistical survey sampled 100 representative orthopaedic papers using a validated questionnaire that assessed the quality of the trial design and statistical analysis methods. The survey found evidence of failings in study design, statistical methodology and presentation of the results. Overall, in 17% (95% confidence interval; 10-26%) of the studies investigated the conclusions were not clearly justified by the results, in 39% (30-49%) of studies a different analysis should have been undertaken and in 17% (10-26%) a different analysis could have made a difference to the overall conclusions. It is only by an improved dialogue between statistician, clinician, reviewer and journal editor that the failings in design methodology and analysis highlighted by this survey can be addressed.

    2004-10-01

    We propose a new approach to realize a bidirectional linear repeater suitable for future optical internet networks and fault location in repeater chain with OTDR. The proposed approach is the linear repeater of simple configuration whose directionality is rearranged dynamically by electrical control signal. The repeater is composed of a magneto-optical switch, a circulator, a dynamically gain stabilized unidirectional EDFA, and control circuits. The repeater directionality is rearranged as fast as 0.1ms by an electrical control pulse. It is experimentally confirmed that OTDR with the directionality switchable repeater is feasible for repeater chain. The detailed design and performance of the repeater are also discussed, including the multi-pass interference (MPI) which may arise in the proposed repeater, the effect of the MPI on SNR degradation of the repeater chain and the feed-forward EDFA gain control circuit.

  2. Measurement-based quantum repeaters

    2012-01-01

    We introduce measurement-based quantum repeaters, where small-scale measurement-based quantum processors are used to perform entanglement purification and entanglement swapping in a long-range quantum communication protocol. In the scheme, pre-prepared entangled states stored at intermediate repeater stations are coupled with incoming photons by simple Bell-measurements, without the need of performing additional quantum gates or measurements. We show how to construct the required resource states, and how to minimize their size. We analyze the performance of the scheme under noise and imperfections, with focus on small-scale implementations involving entangled states of few qubits. We find measurement-based purification protocols with significantly improved noise thresholds. Furthermore we show that already resource states of small size suffice to significantly increase the maximal communication distance. We also discuss possible advantages of our scheme for different set-ups.

    Fast Radio Bursts are millisecond-duration astronomical radio pulses of unknown physical origin that appear to come from extragalactic distances. Previous follow-up observations have failed to find additional bursts at the same dispersion measures (i.e. integrated column density of free electrons between source and telescope) and sky position as the original detections. The apparent non-repeating nature of the fast radio bursts has led several authors to hypothesise that they originate in cataclysmic astrophysical events. Here we report the detection of ten additional bursts from the direction of FRB121102, using the 305-m Arecibo telescope. These new bursts have dispersion measures and sky positions consistent with the original burst. This unambiguously identifies FRB121102 as repeating and demonstrates that its source survives the energetic events that cause the bursts. Additionally, the bursts from FRB121102 show a wide range of spectral shapes that appear to be predominantly intrinsic to the source and wh...

    Interest point detectors are commonly employed to reduce the amount of data to be processed. The ideal interest point detector would robustly select those features which are most appropriate or salient for the application and data at hand. This paper shows that interest points are geometrically stable under different transformations.This property makes interest points very successful in the context of image matching. To measure this property quantatively, we introduce a evaluation criterion: repeatability rate.

  5. Association between blood cadmium levels and 10-year coronary heart disease risk in the general Korean population: the Korean National Health and Nutrition Examination Survey 2008-2010.

    Full Text Available BACKGROUND: Non-occupational heavy metals are considered risk factors for coronary heart disease (CHD. Several recent epidemiologic studies have evaluated the relationship between non-occupational cadmium exposure and risk factors for cardiovascular disease (CVD. This study was designed to investigate the relationship between non-occupational cadmium exposure and risk factors for CHD using the Framingham estimate of 10 year CHD risk. METHODS: The heavy metal dataset of the Korean National Health and Nutrition Examination Survey for 2008 through 2010, a cross-sectional survey of a representative sample of 4,668 non-institutionalized Koreans, was analyzed. Subjects were stratified into seven age groups to minimize the effects of age. The log-transformed blood cadmium concentrations were compared with the Framingham estimate of 10 year CHD risk in each age stratum. RESULTS: The Framingham estimate of 10 year CHD risk was significantly associated with the log-transformed blood cadmium concentrations (p<0.05 in all age groups of Korean men, with the lowest regression coefficient (0.254 for men aged 20 to <35 years and the highest (3.354 for men aged 55 to <60 years; similar results, however, were not observed in Korean women. After adjusting for survey year, age, and urinary cotinine concentration, the log-transformed blood cadmium levels among men aged 20 to <35, 40 to <45, 50 to <55, and 60 to <65 years were significantly associated with systolic blood pressure (p<0.05, but not with total and high density lipoprotein (HDL cholesterol concentrations. CONCLUSIONS: Cadmium exposure, even at non-occupational levels, may be associated with CHD risk in men. Despite the declines in non-occupational cadmium exposure over the past several decades, more efforts are needed.

    In an effort to support mental health policy planning efforts in conjunction with the reconstruction of Iraq, a nationally representative face-to-face household survey was carried out that assessed the prevalence and correlates of common mental disorders in the Iraqi population. A total of 4332 adult (ages 18+) respondents were interviewed (95.2% response rate). The current report presents data on the role impairments (number of days out-of-role in the past 30 days) associated with the nine mental disorders assessed in the survey in comparison to the impairments associated with ten chronic physical disorders also assessed in the survey. These disorders were all assessed with the WHO Composite International Diagnostic Interview. Days out-of-role were assessed with the WHO Disability Assessment Schedule. Both individual-level and societal-level effects of the disorders were estimated. Strongest individual-level predictors were bipolar and drug abuse disorders (176-195 days per year), with mental disorders making up five of the seven strongest predictors. The strongest population-level predictors were headache/migraine and arthritis (22-12% population proportions). Overall population proportions were 57% of days out-of-role due to the chronic physical disorders considered here and 18% for the mental disorders. Despite commonly-occurring mental disorders accounting for more individual-level days out-of-role than the physical disorders, mental disorders are much less likely to receive treatment in Iraq (e.g., due to stigma). These results highlight the need for culturally tailored mental health prevention and treatment programs in Iraq.

  7. Can the use of psychoactive drugs in the general adult population be estimated based on data from a roadside survey of drugs and driving?

    2011-12-01

    Full Text Available A roadside survey of drugs and driving was performed in south-eastern Norway in 2005-6. Samples of saliva from a total of 10,503 drivers above 20 years of age were analysed, and the results were weighted for under- and over-sampling compared to the population distribution in the study area. Weighted results were compared with data on dispensed prescriptions of zopiclone, codeine and diazepam at Norwegian pharmacies in the same area and with self-reported use of cannabis. When using roadside data to estimate drug use, the use of medicinal drugs was under-estimated by 17-59% compared to amounts dispensed. One of the main reasons for the under-estimation may be that a large proportion of the users of psychoactive medicinal drugs are not frequent drivers. For cannabis, self-reported data corresponded approximately to the estimated prevalence range. The results indicate that roadside surveys cannot be used for accurate estima tions of drug use in the population, but may provide minimum figures.

    The quantum internet holds promise for accomplishing quantum teleportation and unconditionally secure communication freely between arbitrary clients all over the globe, as well as the simulation of quantum many-body systems. For such a quantum internet protocol, a general fundamental upper bound on the obtainable entanglement or secret key has been derived [K. Azuma, A. Mizutani, and H.-K. Lo, Nat. Commun. 7, 13523 (2016), 10.1038/ncomms13523]. Here we consider its converse problem. In particular, we present a universal protocol constructible from any given quantum network, which is based on running quantum repeater schemes in parallel over the network. For arbitrary lossy optical channel networks, our protocol has no scaling gap with the upper bound, even based on existing quantum repeater schemes. In an asymptotic limit, our protocol works as an optimal entanglement or secret-key distribution over any quantum network composed of practical channels such as erasure channels, dephasing channels, bosonic quantum amplifier channels, and lossy optical channels.

    We investigated 53 complete bacterial chromosomes for intrachromosomal repeats. In previous studies on eukaryote chromosomes, we proposed a model for the dynamics of repeats based on the continuous genesis of tandem repeats, followed by an active process of high deletion rate, counteracted by rearrangement events that may prevent the repeats from being deleted. The present study of long repeats in the genomes of Bacteria and Archaea suggests that our model of interspersed repeats dynamics may apply to them. Thus the duplication process might be a consequence of very ancient mechanisms shared by all three domains. Moreover, we show that there is a strong negative correlation between nucleotide composition bias and the repeat density of genomes. We hypothesise that in highly biased genomes, non-duplicated small repeats arise more frequently by random effects and are used as primers for duplication mechanisms, leading to a higher density of large repeats.

    Quantum repeaters represent one possible way to achieve long-distance quantum key distribution. One way of improving the repeater rate and decreasing the memory coherence time is the usage of multiplexing. Motivated by the experimental fact that long-range connections are practically demanding, we extend the analysis of the quantum repeater multiplexing protocol to the case of short-range connections. We derive formulas for the repeater rate and we show that short-range connections lead to most of the benefits of a full-range multiplexing protocol. A less demanding QKD-protocol without quantum memories was recently introduced by Lo et al. We generalize this measurement-device-independent quantum key Distribution protocol to the scenario where the repeater Station contains also heralded quantum memories. We assume either single-photon sources or weak coherent pulse sources plus decay states. We show that it is possible to significantly outperform the original proposal, even in presence of decoherence of the quantum memory. We give formulas in terms of device imperfections i.e., the quantum bit error rate and the repeater rate.

    Quantum optical states are fragile and can become corrupted when passed through a lossy communication channel. Unlike for classical signals, optical amplifiers cannot be used to recover quantum signals. Quantum repeaters have been proposed as a way of reducing errors and hence increasing the range of quantum communications. Current protocols target specific discrete encodings, for example quantum bits encoded on the polarization of single photons. We introduce a more general approach that can reduce the effect of loss on any quantum optical encoding, including those based on continuous variables such as the field amplitudes. We show that in principle the protocol incurs a resource cost that scales polynomially with distance. We analyze the simplest implementation and find that while its range is limited it can still achieve useful improvements in the distance over which quantum entanglement of field amplitudes can be distributed.

    Time lapse (4-D) seismic is a promising tool for reservoir characterization and monitoring. The method is apparently simple: to acquire data repeatedly over the same reservoir, process and interpret the data sets, then changes between the data sets indicate changes in the reservoir. A problem with time lapse seismic data is that reservoirs are a relatively small part of the earth and important reservoir changes may cause very small differences to the time lapse data. The challenge is to acquire and process economical time lapse data such that reservoir changes can be detected above the noise of varying acquisition and environment. 7 refs., 9 figs.

    We develop a coordinated hybrid automatic repeat request (HARQ) approach. With the proposed scheme, if a user message is correctly decoded in the first HARQ rounds, its spectrum is allocated to other users, to improve the network outage probability and the users\\' fairness. The results, which are obtained for single- and multiple-antenna setups, demonstrate the efficiency of the proposed approach in different conditions. For instance, with a maximum of M retransmissions and single transmit/receive antennas, the diversity gain of a user increases from M to (J+1)(M-1)+1 where J is the number of users helping that user.

    Full Text Available Background and Objectives: General Practitioners (GPs are generally the first point of contact for children and adolescents with mental health problems. This study investigates the confidence, beliefs, and knowledge of GPs regarding common mental health problems in youngsters. Methods: A self-designed questionnaire was distributed to nearly all registered GPs in a middle-income European country in order to address the aims of the study. Results: Response rate was 58%. Many GPs reported relatively low confidence on a number of issues, including diagnosis (70.0%, initiating management (86.6%, assessing the child-caregiver relationship (72.0% and the ability to distinguish between normal and pathological behavioural problems (75.1%. However, GPs showed greater inclination to conduct follow-up care after assessment by specialist services (53.5%. Few GPs considered psychosocial interventions to play a role in the treatment of anxiety disorders (18.5%, hyperkinetic disorders (24.2%, depression (22.9% and disruptive behaviour disorders (18.5% and this largely came from younger GPs (p < 0.001. Conclusions: Confidence of GPs in the management of youngsters with mental health problems is generally low. They may require significant back-up from specialist services in the form of both training and clinical collaboration.

  17. Crowding by a repeating pattern.

    Rosen, Sarah; Pelli, Denis G

    2015-01-01

    Theinability to recognize a peripheral target among flankers is called crowding. For a foveal target, crowding can be distinguished from overlap masking by its sparing of detection, linear scaling with eccentricity, and invariance with target size.Crowding depends on the proximity and similarity of the flankers to the target. Flankers that are far from or dissimilar to the target do not crowd it. On a gray page, text whose neighboring letters have different colors, alternately black and white, has enough dissimilarity that it might escape crowding. Since reading speed is normally limited by crowding, escape from crowding should allow faster reading. Yet reading speed is unchanged (Chung & Mansfield, 2009). Why? A recent vernier study found that using alternating-color flankers produces strong crowding (Manassi, Sayim, & Herzog, 2012). Might that effect occur with letters and reading? Critical spacing is the minimum center-to-center target-flanker spacing needed to correctly identify the target. We measure it for a target letter surrounded by several equidistant flanker letters of the same polarity, opposite polarity, or mixed polarity: alternately white and black. We find strong crowding in the alternating condition, even though each flanker letter is beyond its own critical spacing (as measured in a separate condition). Thus a periodic repeating pattern can produce crowding even when the individual elements do not. Further, in all conditions we find that, once a periodic pattern repeats (two cycles), further repetition does not affect critical spacing of the innermost flanker.

Inconsistent results may be partly explained by the fact that use of supplements is an inconsistent behavior in individuals. We examined whether vitamin supplement use patterns affect cancer and CVD risk in a population-based cohort study in Japan. Methods A total of 28,903 men and 33,726 women in the Japan Public Health Center-based Prospective Study cohort, who answered questions about vitamin supplement use in the first survey from 1990-1994 and the second survey from 1995-1998, were categorized into four groups (never use, past use, recent use, and consistent use and followed to the end of 2006 for cancer and 2005 for CVD. Sex-specific hazard ratios (HRs and 95% confidence intervals (95% CIs were used to describe the relative risks of cancer and CVD associated with vitamin supplement use. Results During follow-up, 4501 cancer and 1858 CVD cases were identified. Multivariate adjusted analysis revealed no association of any pattern of vitamin supplement use with the risk of cancer and CVD in men. In women, consistent use was associated with lower risk of CVD (HR 0.60, 95% CI 0.41-0.89, whereas past (HR 1.17, 95% CI 1.02-1.33 and recent use (HR 1.24, 95% CI 1.01-1.52 were associated with higher risk of cancer. Conclusions To our knowledge, this is the first prospective cohort study to examine simultaneously the associations between vitamin supplement use patterns and risk of cancer and CVD. This prospective cohort study demonstrated that vitamin supplement use has little effect on the risk of cancer or CVD in men. In women, however, consistent vitamin supplement use might reduce the risk of CVD. Elevated risk of cancer associated with past and recent use of vitamin supplements in women may be partly

    Full Text Available Abstract Background Public drug insurance plans provide limited reimbursement for Alzheimer's disease (AD medications in many jurisdictions, including Canada and the United Kingdom. This study was conducted to assess Canadians' level of support for an increase in annual personal income taxes to fund a public program of unrestricted access to AD medications. Methods A telephone survey was administered to a national sample of 500 adult Canadians. The survey contained four scenarios describing a hypothetical, new AD medication. Descriptions varied across scenarios: the medication was alternatively described as being capable of treating the symptoms of cognitive decline or of halting the progression of cognitive decline, with either no probability of adverse effects or a 30% probability of primarily gastrointestinal adverse effects. After each scenario, participants were asked whether they would support a tax increase to provide unrestricted access to the drug. Participants who responded affirmatively were asked whether they would pay an additional $75, $150, or $225 per annum in taxes. Multivariable logistic regression analysis was conducted to examine the determinants of support for a tax increase. Results Eighty percent of participants supported a tax increase for at least one scenario. Support was highest (67% for the most favourable scenario (halt progression - no adverse effects and lowest (49% for the least favourable scenario (symptom treatment - 30% chance of adverse effects. The odds of supporting a tax increase under at least one scenario were approximately 55% less for participants who attached higher ratings to their health state under the assumption that they had moderate AD and almost five times greater if participants thought family members or friends would somewhat or strongly approve of their decision to support a tax increase. A majority of participants would pay an additional $150 per annum in taxes, regardless of scenario. Less

    The primary objective of this study was to estimate the association between blood mercury levels and overweight in Korean adults. We analyzed cross-sectional data from 9228 participants (4283 men and 4945 women) who completed the Korean National Health and Nutrition Examination Survey (KNHANES), 2007-2013. The population was divided into two groups according to the body mass index (BMI) and waist circumference (WC). Blood mercury levels were analyzed using a gold amalgam method with a DMA-80 instrument, categorized into quartiles, and stratified by sex. After adjusting for all covariates, blood mercury was significantly associated with overweight in all subjects. According to the BMI criteria, the adjusted odds ratio of being in the highest blood mercury quartile was 1.75 (95 % confidence interval [CI], 1.53-2.01) overall, 2.09 (95 % CI, 1.71-2.55) in men, and 1.58 (95 % CI, 1.32-1.89) in women. According to the WC criteria, the adjusted odds ratio of being in the highest blood mercury quartile was 1.85 (95 % CI, 1.49-2.30) in men and 1.96 (95 % CI, 1.62-2.36) in women compared to the lowest quartile. Additionally, a trend in overweight across increasing blood mercury levels was observed by the p for trend test in the multiple diagnostic criteria.

    Full Text Available Abstract Background Genome wide and cross species comparisons of amino acid repeats is an intriguing problem in biology mainly due to the highly polymorphic nature and diverse functions of amino acid repeats. Innate protein repeats constitute vital functional and structural regions in proteins. Repeats are of great consequence in evolution of proteins, as evident from analysis of repeats in different organisms. In the post genomic era, availability of protein sequences encoded in different genomes provides a unique opportunity to perform large scale comparative studies of amino acid repeats. ProtRepeatsDB http://bioinfo.icgeb.res.in/repeats/ is a relational database of perfect and mismatch repeats, access to which is designed as a resource and collection of tools for detection and cross species comparisons of different types of amino acid repeats. Description ProtRepeatsDB (v1.2 consists of perfect as well as mismatch amino acid repeats in the protein sequences of 141 organisms, the genomes of which are now available. The web interface of ProtRepeatsDB consists of different tools to perform repeat s; based on protein IDs, organism name, repeat sequences, and keywords as in FASTA headers, size, frequency, gene ontology (GO annotation IDs and regular expressions (REGEXP describing repeats. These tools also allow formulation of a variety of simple, complex and logical queries to facilitate mining and large-scale cross-species comparisons of amino acid repeats. In addition to this, the database also contains sequence analysis tools to determine repeats in user input sequences. Conclusion ProtRepeatsDB is a multi-organism database of different types of amino acid repeats present in proteins. It integrates useful tools to perform genome wide queries for rapid screening and identification of amino acid repeats and facilitates comparative and evolutionary studies of the repeats. The database is useful for identification of species or organism specific

    Chronic obstructive pulmonary disease (COPD) is a common chronic disease, being associated with both high rates of morbidity and mortality. Similarly, atrial fibrillation (AF) is associated with a higher risk of both cardiovascular (CV) events and overall mortality. The AF and COPD often coexist, but the impact of COPD on prognosis in European AF patients is unknown. We evaluated COPD prevalence in patients enrolled in the EURObservational Research Programme Pilot Survey on Atrial Fibrillation Registry Pilot Phase. Clinical factors associated with COPD and adverse outcomes at 1-year follow-up were determined. In the overall cohort, a diagnosis of COPD was recorded in 339 (11.0%) of AF patients. The AF patients with COPD were more burdened with risk factors and comorbidities, including diabetes mellitus (P < .0001) and chronic heart failure (P < .0001). β-Blockers were less likely to be prescribed to patients with COPD (P = .0007). On follow-up, AF patients with COPD had a higher risk of both CV death and all-cause death (both P < .0001), as well as for the composite outcome of any thromboembolic event/bleeding /CV death (P = .0003). Cox regression analysis found that COPD was independently associated with an increase in all-cause death (hazard ratio, 1.55; 95% CI 1.05-2.28; P = .0269). Chronic obstructive pulmonary disease is highly prevalent in European AF patients, and is associated with higher rates of CV death, all-cause death, and the composite outcome of any thromboembolic event/bleeding/CV death. The presence of COPD in AF patients was independently associated with all-cause death in AF patients. Copyright © 2016 Elsevier Inc. All rights reserved.

    Background We investigated the prevalence, awareness, treatment, and control rate of hypertension in Korean adults with diabetes using nationally representative data. Methods Using data of 5,105 adults from the fifth Korea National Health and Nutrition Examination Survey in 2011 (4,389 nondiabetes mellitus [non-DM]), 242 newly diagnosed with DM (new-DM), and 474 previously diagnosed with DM (known-DM), we analyzed the prevalence of hypertension (mean systolic blood pressure ≥140 mm Hg, diastolic blood pressure ≥90 mm Hg, or use of antihypertensive medication) and control rate of hypertension (blood pressure [BP] <130/80 mm Hg). Results The prevalence of hypertension in diabetic adults was 54.6% (44.4% in new-DM and 62.6% in known-DM, P<0.0001 and P<0.0001, respectively) compared with non-DM adults (26.2%). Compared to non-DM, awareness (85.7%, P<0.001) and treatment (97.0%, P=0.020) rates were higher in known-DM, whereas no differences were found between new-DM and non-DM. Control rate among all hypertensive subjects was lower in new-DM (14.9%), compared to non-DM (35.1%, P<0.001) and known-DM (33.3%, P=0.004). Control rate among treated subjects was also lower in new-DM (25.2%), compared to non-DM (68.4%, P<0.0001) and known-DM (39.9%, P<0.0001). Conclusion Higher prevalence and low control rate of hypertension in adults with diabetes suggest that stringent efforts are needed to control BP in patients with diabetes, particularly in newly diagnosed diabetic patients.

    Our dataset contains spectroscopic observations of 29 globular clusters in the Magellanic Clouds and the Milky Way performed with VLT/X-shooter. Here we present detailed data reduction procedures for the VLT/X-shooter UVB and VIS arm. These are not restricted to our particular dataset, but are generally applicable to different kinds of X-shooter data without major limitation on the astronomical object of interest. The packaged pipeline provided by ESO (v1.5.0) performs well and reliably for the wavelength calibration and the associated rectification procedure, yet we find several weaknesses in the reduction cascade that are addressed with additional calibration steps, such as bad pixel interpolation, flat fielding, and slit illumination corrections. Furthermore, the instrumental PSF is analytically modeled and used to reconstruct flux losses at slit transit and for optimally extracting point sources. Regular observations of spectrophotometric standard stars allow us to detect instrumental variability, which n...

    Full Text Available OBJECTIVE: This paper reports the first population estimates of prevalence and correlates of personality disorders in the Mexican population. METHOD: Personality disorders screening questions from the International Personality Disorder Examination were administered to a representative sample of the Mexican urban adult population (n = 2,362 as part of the Mexican National Comorbidity Survey, validated with clinical evaluations conducted in the United States. A multiple imputation method was then implemented to estimate prevalence and correlates of personality disorder in the Mexican sample. RESULTS: Multiple imputation method prevalence estimates were 4.6% Cluster A, 1.6% Cluster B, 2.4% Cluster C, and 6.1% any personality disorder. All personality disorders clusters were significantly comorbid with DSM-IV Axis I disorders. One in every five persons with an Axis I disorder in Mexico is likely to have a comorbid personality disorder, and almost half of those with a personality disorder are likely to have an Axis I disorder. CONCLUSIONS: Modest associations of personality disorders with impairment and strong associations with treatment utilization were largely accounted for by Axis I comorbidity suggesting that the public health significance of personality disorders lies in their comorbidity with, and perhaps effects upon, Axis I disorders rather than their direct effects on functioning and help seeking.OBJETIVO: Este trabajo presenta las primeras estimaciones poblacionales de la prevalencia de los trastornos de personalidad y sus correlatos en la población mexicana.

    Despite recent improvements in the oral health of Scotland's population, the persistence of childhood dental caries underscores a need to reduce the disease burden experienced by children living in Scotland. Application of fluoride varnish (FV) to children's teeth provides an evidence-based approach to achieving this goal. Despite policy, health service targets and professional recommendations supporting application, not all children receive FV in line with guidance. The objective of this study was to use the theoretical domains framework (TDF) to further an understanding of what may influence fluoride varnish application (FVA) in General Dental Practice in Scotland. A postal questionnaire assessing current behaviour (frequency of FVA) and theoretical domains (TDs) was sent to all General Dental Practitioners (GDPs) in Scotland. Correlations and linear regression models were used to examine the association between FVA and the TDs. One thousand and ninety (53.6%) eligible GDPs responded. Respondents reported applying FV more frequently to increased risk and younger children (aged 2-5 years). Higher scores in eight TDs (Knowledge, Social/professional role and identity, Beliefs about consequences, Motivation and goals, Environmental context and resources, Social influences, Emotion and Behavioural regulation) were associated with greater frequency of FVA. Four beliefs in particular appear to be driving GDPs' decision to apply FV (recognizing that FVA is a guideline recommended behaviour (Knowledge), that FVA is perceived as an important part of the GDPs' professional role (Professional role/identity), that FV is something parents want for their children (Social influences) and that FV is something GDPs really wanted to do (Emotion). The findings of this study support the use of the TDF as a tool to understand GDPs application of FV and suggest that a multifaceted intervention, targeting dental professionals and families, and more specifically those domains and items

    Barkan, Alice; Small, Ian

    2014-01-01

    Pentatricopeptide repeat (PPR) proteins constitute one of the largest protein families in land plants, with more than 400 members in most species. Over the past decade, much has been learned about the molecular functions of these proteins, where they act in the cell, and what physiological roles they play during plant growth and development. A typical PPR protein is targeted to mitochondria or chloroplasts, binds one or several organellar transcripts, and influences their expression by altering RNA sequence, turnover, processing, or translation. Their combined action has profound effects on organelle biogenesis and function and, consequently, on photosynthesis, respiration, plant development, and environmental responses. Recent breakthroughs in understanding how PPR proteins recognize RNA sequences through modular base-specific contacts will help match proteins to potential binding sites and provide a pathway toward designing synthetic RNA-binding proteins aimed at desired targets.

    The endeavor to develop quantum networks gave rise to a rapidly developing field with far-reaching applications such as secure communication and the realization of distributed computing tasks. This ultimately calls for the creation of flexible multiuser structures that allow for quantum communication between arbitrary pairs of parties in the network and facilitate also multiuser applications. To address this challenge, we propose a two-dimensional quantum repeater architecture to establish long-distance entanglement shared between multiple communication partners in the presence of channel noise and imperfect local control operations. The scheme is based on the creation of self-similar multiqubit entanglement structures at growing scale, where variants of entanglement swapping and multiparty entanglement purification are combined to create high-fidelity entangled states. We show how such networks can be implemented using trapped ions in cavities.

    Full Text Available Most of the debate ¡s about how the slow or frequent turnover of fresh fat affects the deterioration, of fat used in frying. Then, the modification of different oils used in repeated fryings of potatoes without or with turnover of fresh oil, under similar frying conditions, was evaluated by two criteria: by measuring the total polar component isolated by column chromatography and by the evaluation of the specific compounds related to thermoxidative and hydrolytic alteration by High Performance Size Exclusion Chromatography (HPSEC. The results indicate that with frequent turnover of fresh oil, the critical level of 25% of polar material is rarely reached, and there are fewer problems with fat deterioration because the frying tended to increase the level of polar material and thermoxidative compounds (polymers and dimers of triglycerides and oxidized triglycerides in the fryer oil during the first fryings, followed by minor changes and a tendency to reach a near-steady state in successive fryings. However, in repeated frying of potatoes using a null turnover the alteration rate was higher being linear the relationship found between polar material or the different thermoxidative compounds and the number of fryings. On the other hand chemical reactions produced during deep-fat frying can be minimized by using proper oils. In addition the increased level of consumers awareness toward fat composition and its impact on human health could had an impact on the selection of fats for snacks and for industry. In this way monoenic fats are the most adequate from a nutritional point of view and for its oxidative stability during frying.

  17. Repeated Games With Intervention: Theory and Applications in Communications

    Xiao, Yuanzhang; van der Schaar, Mihaela

    2011-01-01

    In communication systems where users share common resources, users' selfish behavior usually results in suboptimal resource utilization. There have been extensive works that model communication systems with selfish users as one-shot games and propose incentive schemes to achieve Pareto optimal action profiles as non-cooperative equilibria. However, in many communication systems, due to strong negative externalities among users, the sets of feasible payoffs in one-shot games are nonconvex. Thus, it is possible to expand the set of feasible payoffs by having users choose convex combinations of different payoffs. In this paper, we propose a repeated game model generalized by intervention. First, we use repeated games to convexify the set of feasible payoffs in one-shot games. Second, we combine conventional repeated games with intervention, originally proposed for one-shot games, to achieve a larger set of equilibrium payoffs and loosen requirements for users' patience to achieve it. We study the problem of maxi...

  19. The mitochondrial genome of the legume Vigna radiata and the analysis of recombination across short mitochondrial repeats.

    Directory of Open Access Journals (Sweden)

    Andrew J Alverson

    Full Text Available The mitochondrial genomes of seed plants are exceptionally fluid in size, structure, and sequence content, with the accumulation and activity of repetitive sequences underlying much of this variation. We report the first fully sequenced mitochondrial genome of a legume, Vigna radiata (mung bean, and show that despite its unexceptional size (401,262 nt, the genome is unusually depauperate in repetitive DNA and "promiscuous" sequences from the chloroplast and nuclear genomes. Although Vigna lacks the large, recombinationally active repeats typical of most other seed plants, a PCR survey of its modest repertoire of short (38-297 nt repeats nevertheless revealed evidence for recombination across all of them. A set of novel control assays showed, however, that these results could instead reflect, in part or entirely, artifacts of PCR-mediated recombination. Consequently, we recommend that other methods, especially high-depth genome sequencing, be used instead of PCR to infer patterns of plant mitochondrial recombination. The average-sized but repeat- and feature-poor mitochondrial genome of Vigna makes it ever more difficult to generalize about the factors shaping the size and sequence content of plant mitochondrial genomes.

    Naturopathy forms an increasingly significant part of the Australian healthcare setting, with high utilisation of naturopaths by the Australian public and a large therapeutic footprint in rural and regional Australia. However, despite these circumstances, there has been little exploration of the interface between naturopathy providers and conventional primary health care practitioners in rural and regional Australia. The study reported here examined the referral practices and factors that underlie referral to naturop
