Developing agreement on never events in primary care dentistry:an international eDelphi study

Introduction: Never events (NEs) are a subset of serious patient safety incidents that should not occur if appropriate preventive measures are implemented. Although there is a consensus in medicine, there is no agreement on NEs in dentistry. Aim: To identify NEs in primary care dentistry. Method: We undertook an electronic Delphi exercise to develop an international agreement on NEs for primary care dentistry. Results: We initially identified candidate NEs through a scoping review of the literature and then analysed dentistry-related reports in a national incident reporting system. Next, we invited an international panel of 41 experts to complete two rounds of questionnaires; 32 agreed to participate (78%) and completed the first round and 29/41 (71%) members completed the second round. We provided anonymised controlled feedback between rounds and used a cut-off of 80% agreement to define consensus. Consensus was achieved for 23 out of 42 candidate NEs. These related to routine assessment, and pre-operative, intra-operative and post-operative stages of dental procedures. Discussion and conclusion: To our knowledge, this is the first international expert consensus-based approach that has identified NEs for primary care dentistry. We suggest that dental regulators consider these to support quality assessment and governance activities

Very Low-mass Stellar and Substellar Companions to Solar-like Stars from MARVELS II: A Short-period Companion Orbiting an F Star with Evidence of a Stellar Tertiary And Significant Mutual Inclination

We report the discovery via radial velocity of a short-period (P = 2.430420 \pm 0.000006 days) companion to the F-type main sequence star TYC 2930-00872-1. A long-term trend in the radial velocities indicates the presence of a tertiary stellar companion with $P > 2000$ days. High-resolution spectroscopy of the host star yields T_eff = 6427 +/- 33 K, log(g) = 4.52 +/- 0.14, and [Fe/H]=-0.04 +/- 0.05. These parameters, combined with the broad-band spectral energy distribution and parallax, allow us to infer a mass and radius of the host star of M_1=1.21 +/- 0.08 M_\odot and R_1=1.09_{-0.13}^{+0.15} R_\odot. We are able to exclude transits of the inner companion with high confidence. The host star's spectrum exhibits clear Ca H and K core emission indicating stellar activity, but a lack of photometric variability and small v*sin(I) suggest the primary's spin axis is oriented in a pole-on configuration. The rotational period of the primary from an activity-rotation relation matches the orbital period of the inner companion to within 1.5 \sigma, suggesting they are tidally locked. If the inner companion's orbital angular momentum vector is aligned with the stellar spin axis, as expected through tidal evolution, then it has a stellar mass of M_2 ~ 0.3-0.4 M_\odot. Direct imaging limits the existence of stellar companions to projected separations < 30 AU. No set of spectral lines and no significant flux contribution to the spectral energy distribution from either companion are detected, which places individual upper mass limits of M < 1.0 M_\odot, provided they are not stellar remnants. If the tertiary is not a stellar remnant, then it likely has a mass of ~0.5-0.6 M_\odot, and its orbit is likely significantly inclined from that of the secondary, suggesting that the Kozai-Lidov mechanism may have driven the dynamical evolution of this system.Comment: 37 pages, 7 tables, 21 figures, Accepted in A

EuCAPT White Paper: Opportunities and Challenges for Theoretical Astroparticle Physics in the Next Decade

Astroparticle physics is undergoing a profound transformation, due to a series of extraordinary new results, such as the discovery of high-energy cosmic neutrinos with IceCube, the direct detection of gravitational waves with LIGO and Virgo, and many others. This white paper is the result of a collaborative effort that involved hundreds of theoretical astroparticle physicists and cosmologists, under the coordination of the European Consortium for Astroparticle Theory (EuCAPT). Addressed to the whole astroparticle physics community, it explores upcoming theoretical opportunities and challenges for our field of research, with particular emphasis on the possible synergies among different subfields, and the prospects for solving the most fundamental open questions with multi-messenger observations.Comment: White paper of the European Consortium for Astroparticle Theory (EuCAPT). 135 authors, 400 endorsers, 133 pages, 1382 reference

Psychometric Properties and Correlates of Precarious Manhood Beliefs in 62 Nations

Precarious manhood beliefs portray manhood, relative to womanhood, as a social status that is hard to earn, easy to lose, and proven via public action. Here, we present cross-cultural data on a brief measure of precarious manhood beliefs (the Precarious Manhood Beliefs scale [PMB]) that covaries meaningfully with other cross-culturally validated gender ideologies and with country-level indices of gender equality and human development. Using data from university samples in 62 countries across 13 world regions (N = 33,417), we demonstrate: (1) the psychometric isomorphism of the PMB (i.e., its comparability in meaning and statistical properties across the individual and country levels); (2) the PMB’s distinctness from, and associations with, ambivalent sexism and ambivalence toward men; and (3) associations of the PMB with nation-level gender equality and human development. Findings are discussed in terms of their statistical and theoretical implications for understanding widely-held beliefs about the precariousness of the male gender role

Using Evolutionary Computation for Seismic Signal Detection: A Homeland Security Application

Abstract – Many organizations and governments have the need to monitor areas for intrusions and, once detected, to identify the type of potential intruder(s) present. Applications include perimeter security at installations such as airports and critical infrastructure, as well as military situation awareness in monitoring demilitarized zones, or other areas where activity of interest may occur. Seismic signal detectors can be used in many of these applications. Timefrequency response (TFR) signals are generated and must be classified as being generated by particular targets of interest. Experiments were conducted using real data collected at Marine Corps Base, Camp Pendleton, California, USA. Seismic signal detectors were used to monitor signals generated by individual people, groups of people, and vehicles of different types. Evolutionary computation was combined with neural networks to analyze the TFR signals and classify the acquired data. The results indicated the practical application of classifying signals based on their seismic signature

Evolving artificial neural networks for screening features from mammograms

Disagreement or inconsistencies in mammographic interpretation motivates utilizing computerized pattern recognition algorithms to aid the assessment of radiographic features. We have studied the potential for using artificial neural networks (ANNs) to analyze interpreted radiographic features from film screen mammograms. Attention was given to 216 cases (mammogram series) that presented suspicious characteristics. The domain expert (Wasson) quantified up to 12 radiographic features for each case based on guidelines from previous literature. Patient age was also included. The existence or absence of malignancy was confirmed in each case via open surgical biopsy (111 malignant, 105 benign). ANNs of various complexity were trained via evolutionary programming to indicate whether or not a malignancy was present given a vector of scored input features in a statistical cross validation procedure. For suspicious masses, the best evolved ANNs generated a mean area under the receiver operating characteristic curve (A Z) of 0.9196�0.0040 (1 S.E.), with a mean specificity of 0.6269�0.0272 at 0.95 sensitivity. Results when microcalcifications were included were not quite as good (A Z=0.8464), however, ANNs with only two hidden nodes performed as well as more complex ANNs and better than ANNs with only one hidde

O exercício físico influencia a postura corporal de idosas? Does exercise influence the body posture in elderly women?

As alterações posturais associadas ao envelhecimento influem diretamente no desempenho de atividades da vida diária. E o exercício físico tem sido utilizado como forma de prevenção aos desgastes causados pelo avanço da idade. Este estudo objetivou comparar o perfil postural no plano sagital de idosas participantes do Estudo Multidimensional dos Idosos de Porto Alegre (EMIPOA) e idosas participantes de um programa de exercícios físicos (GEF), através de avaliação com o uso de posturógrafo. Utilizou-se o protocolo de Kendall, Mccreary e Provance (1995) para análise e classificação das posturas. Para o tratamento dos dados, foi utilizada estatística descritiva e teste de Kolmogorov-Smirnov (&#945;<0,05) para comparação dos dois grupos. O perfil postural predominante nos grupos foi cifose-lordose. Não foi encontrada diferença significativa de predominância de perfil postural entre os grupos. Os resultados sugerem que o programa de exercícios não foi eficaz para produzir alterações do perfil postural no plano sagital para idosas.<br>Age-associated postural changes directly affect daily-task performance. Exercise has been used in order prevent impairments caused by aging process. This study has aimed to compare the postural profile at the sagittal plane of elderly women participants of the Multidimensional Study of Elderly in Porto Alegre (EMIPOA) and elderly women engaged in an exercise program (GEF) through posture grad assessment. Posterior image analysis and posture classification was done as described by Kendall, Mccreary e Provance (1995). We used descriptive statistics and the Kolmogorov-Smirnov test (&#945;<0.05) to compare the results of the groups. Both groups presented the kyphosis-lordosis as predominant posture profile. There was no significant difference in prevalence of postural profile between EMIPOA and GEF. Results suggest that the exercise program was not effective to produce postural changes at the sagittal plane for elderly women
