Disfluências e velocidade de fala em produção espontânea e em leitura oral em indivíduos gagos e não gagos

PURPOSE: To investigate and characterize temporal parameters of speech in spontaneous situation and in oral reading in people who stutter and who do not stutter, and investigate the relation among these variables. METHODS: Thirty participants aged between 17 and 59 years, with a minimum of 08 years of scholar education, constituted the Study Group, composed by 15 people who stutter and the Control Group with 15 people who did not stutter. Subjects on the Control and Study Group were matched by gender, age and education level. After anamnesis it was made: brief neuropsychological assessment, specific stuttering assessment and specific oral reading assessment. Disfluencies were analyzed and it was calculated speech rate on spontaneous production and oral reading. RESULTS: There were more disfluencies in spontaneous speech than in text oral reading in both groups. As to speech rate, in the Control Group, pseudoword and text reading were positively correlated, and in the Study Group, all variables were positively correlated. CONCLUSION: Speech rate and disfluencies analysis characterized both groups, either in spontaneous speech and reading situations which evidenced performance profiles differentiated by speech rate, frequency and disfluency typology. Investigation showed that people who stutter present lower values of speech rate, as well as higher occurrence of disfluencies, either on spontaneous speech and oral reading, in comparison to people who do not stutter.OBJETIVO: Investigar e caracterizar a velocidade de fala e as rupturas da fala em situação espontânea e em leitura oral, em indivíduos gagos e não gagos e investigar a relação entre essas variáveis. MÉTODOS: Trinta participantes com idades entre 17 e 59 anos e, no mínimo, oito anos de escolaridade, constituíram o Grupo Estudo, com 15 indivíduos gagos, e o Grupo Controle, com 15 indivíduos não gagos. Os indivíduos do Grupo Controle e do Grupo Estudo foram pareados por idade, gênero e nível de escolaridade. Após anamnese, foram realizadas as seguintes avaliações: neuropsicológica breve, específica da gagueira e específicas da leitura. As disfluências foram analisadas e calculou-se a velocidade da fala espontânea e na leitura oral. RESULTADOS: Ocorreram mais disfluências na fala espontânea que na leitura oral de texto, em ambos os grupos. Em relação à velocidade, no Grupo Controle, a leitura de pseudopalavras e de texto correlacionaram-se positivamente e no Grupo Estudo, todas as variáveis correlacionaram-se positivamente. CONCLUSÃO: A análise da velocidade e das rupturas de fala caracterizou ambos os grupos, tanto em situação de fala espontânea, quanto na leitura que evidencia perfis de desempenho diferenciados pela velocidade de fala, frequência e tipologia das rupturas. A investigação demonstra que indivíduos gagos apresentaram valores mais baixos de velocidade, assim como maior ocorrência de disfluências, tanto na fala espontânea quanto na leitura oral, em comparação com indivíduos não gagos.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Universidade Federal de São Paulo (UNIFESP)Universidade Federal de São Paulo (UNIFESP) Departamento de FonoaudiologiaUNIFESP, Depto. de FonoaudiologiaSciEL

Pharmacokinetic aspects of retinal drug delivery

Drug delivery to the posterior eye segment is an important challenge in ophthalmology, because many diseases affect the retina and choroid leading to impaired vision or blindness. Currently, intravitreal injections are the method of choice to administer drugs to the retina, but this approach is applicable only in selected cases (e.g. anti-VEGF antibodies and soluble receptors). There are two basic approaches that can be adopted to improve retinal drug delivery: prolonged and/or retina targeted delivery of intravitreal drugs and use of other routes of drug administration, such as periocular, suprachoroidal, sub-retinal, systemic, or topical. Properties of the administration route, drug and delivery system determine the efficacy and safety of these approaches. Pharmacokinetic and pharmacodynamic factors determine the required dosing rates and doses that are needed for drug action. In addition, tolerability factors limit the use of many materials in ocular drug delivery. This review article provides a critical discussion of retinal drug delivery, particularly from the pharmacokinetic point of view. This article does not include an extensive review of drug delivery technologies, because they have already been reviewed several times recently. Instead, we aim to provide a systematic and quantitative view on the pharmacokinetic factors in drug delivery to the posterior eye segment. This review is based on the literature and unpublished data from the authors' laboratory.Peer reviewe

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Abstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

Measurement of the associated production of a Higgs boson decaying into b-quarks with a vector boson at high transverse momentum in pp collisions at s=13\sqrt{s}=13 TeV with the ATLAS detector

The associated production of a Higgs boson with a W or Z boson decaying into leptons and where the Higgs boson decays to a pair is measured in the high vector-boson transverse momentum regime, above 250 GeV, with the ATLAS detector. The analysed data, corresponding to an integrated luminosity of , were collected in proton–proton collisions at the Large Hadron Collider between 2015 and 2018 at a centre-of-mass energy of . The measured signal strength, defined as the ratio of the measured signal yield to that predicted by the Standard Model, is corresponding to an observed (expected) significance of 2.1 (2.7) standard deviations. Cross-sections of associated production of a Higgs boson decaying into b quark pairs with a W or Z gauge boson, decaying into leptons, are measured in two exclusive vector boson transverse momentum regions, 250–400 GeV and above 400 GeV, and interpreted as constraints on anomalous couplings in the framework of a Standard Model effective field theory

Search for dark matter in events with missing transverse momentum and a Higgs boson decaying into two photons in pp collisions at root s=13 TeV with the ATLAS detector

A search for dark-matter particles in events with large missing transverse momentum and a Higgs boson candidate decaying into two photons is reported. The search uses 139 fb−1 of proton-proton collision data collected at s√ = 13 TeV with the ATLAS detector at the CERN LHC between 2015 and 2018. No significant excess of events over the Standard Model predictions is observed. The results are interpreted by extracting limits on three simplified models that include either vector or pseudoscalar mediators and predict a final state with a pair of dark-matter candidates and a Higgs boson decaying into two photons

Muon reconstruction and identification efficiency in ATLAS using the full Run 2 pp collision data set at \sqrt{s}=13 TeV

This article documents the muon reconstruction and identification efficiency obtained by the ATLAS experiment for 139 \hbox {fb}^{-1} of pp collision data at \sqrt{s}=13 TeV collected between 2015 and 2018 during Run 2 of the LHC. The increased instantaneous luminosity delivered by the LHC over this period required a reoptimisation of the criteria for the identification of prompt muons. Improved and newly developed algorithms were deployed to preserve high muon identification efficiency with a low misidentification rate and good momentum resolution. The availability of large samples of Z\rightarrow \mu \mu and J/\psi \rightarrow \mu \mu decays, and the minimisation of systematic uncertainties, allows the efficiencies of criteria for muon identification, primary vertex association, and isolation to be measured with an accuracy at the per-mille level in the bulk of the phase space, and up to the percent level in complex kinematic configurations. Excellent performance is achieved over a range of transverse momenta from 3 GeV to several hundred GeV, and across the full muon detector acceptance of |\eta |<2.7

Measurements of Higgs bosons decaying to bottom quarks from vector boson fusion production with the ATLAS experiment at √=13TeV

The paper presents a measurement of the Standard Model Higgs Boson decaying to b-quark pairs in the vector boson fusion (VBF) production mode. A sample corresponding to 126 fb−1 of s√=13TeV proton–proton collision data, collected with the ATLAS experiment at the Large Hadron Collider, is analyzed utilizing an adversarial neural network for event classification. The signal strength, defined as the ratio of the measured signal yield to that predicted by the Standard Model for VBF Higgs production, is measured to be 0.95+0.38−0.36 , corresponding to an observed (expected) significance of 2.6 (2.8) standard deviations from the background only hypothesis. The results are additionally combined with an analysis of Higgs bosons decaying to b-quarks, produced via VBF in association with a photon

(Bio)ética e Atenção Primária à Saúde: estudo preliminar nas Clínicas da Família no município do Rio de Janeiro, Brasil

Resumo A Estratégia Saúde da Família (ESF) – iniciada como Programa de Saúde da Família (PSF), em 1994 – vem sendo pensada e trabalhada, no Brasil, como lógica prioritária para reorganização da Atenção Primária à Saúde (APS). A transformação do modelo hegemônico de APS em ESF tem promovido várias mudanças no modo de trabalho em saúde, cujos impactos em diferentes esferas – por exemplo, (bio)éticas – ainda precisam ser elucidados. Nesse contexto, realizou-se a presente investigação, caracterizada como estudo exploratório e dirigida ao mapeamento dos principais problemas (bio)éticos identificados pelos trabalhadores da APS do município do RJ. Para isso, utilizou-se um questionário – aplicado aos profissionais das Clínicas da Família (CF) – para coleta de informações, procedendo-se a análise de conteúdo, de acordo com o proposto por Bardin. O trabalho na APS no contexto da CF, possui particularidades em termos das relações (bio)éticas estabelecidas nesse nível de atenção à saúde. Assim, a proposição de novos referenciais teóricos e o desenvolvimento de ações educativas usualmente utilizadas para a abordagem das questões tornam-se extremamente necessários
