Mapeamento da produção artístico-acadêmica de Dança nos programas brasileiros de pós-graduação em Artes: um olhar sobre os métodos de investigação / Mapping the artistic-academic production of Dance in brazilian postgraduate Arts programs: a look at research methods / Mapeo de la producción artístico-académica de la Danza en los programas de posgrado en Arte brasileños: una mirada a los métodos de investigación

Este artigo teve como objetivo identificar a localidade da Dança nos métodos de pesquisa das teses e dissertações, produzidas entre 2016-2020, nos programas de pós-graduação em Artes no Brasil. O percurso metodológico, de caráter descritivo, se deu a partir da observação da lógica adotada na organização das investigações (produção de uma performance, distanciamento para teorizar, utilização para fins dedutivos) e classificou a localidade da Dança como: (a) produção e interpretação dos dados; (b) objeto; (c) experimento. O estudo constatou que a maior parte dos trabalhos, de acordo com o período levantado, localizam a Dança nos seus percursos metodológicos como objeto de estudo. Apesar da busca por um caminho do exercício de observação e teorização, percebe-se que existe um amplo leque de possibilidades de experimentações, desdobramentos, especulações e conjecturas sobre o lugar da Dança nos métodos de pesquisas brasileiros (AU).

This article aimed to identify the location of Dance in the research methods of theses and dissertations, produced bet-ween 2016-2020, in postgraduate programs in Arts in Brazil. The methodological course, of a descriptive character, was based on the observation of the logic adopted in the organization of investi-gations (production of a performance, distance to theorize, use for deductive purposes) and classified the locality of Dance as: (a) pro-duction and interpretation of the data; (b) object; (c) experiment. The study found that most of the works, according to the period surveyed, locate Dance in their methodological paths as an object of study. Despite the search for a way of exercising observation and theorization, it is clear that there is a wide range of possibili-ties for experimentation, developments, speculations and conjec-tures about the place of Dance in Brazilian research methods (AU).

Efeito da padronização dos critérios de observação e de avaliação da técnica da braça do nado crawl na confiabilidade inter e intra avaliadores / Effect of standardizing observation and rating criteria for the front crawl stroke technique on inter- and intra-rater reliability

RESUMO Esse estudo teve por objetivo avaliar o efeito da padronização dos critérios de observação e de avaliação da técnica da braçada do nado crawl na confiabilidade inter e intra avaliadores para uma proposta de lista de observação. Dois professores e dois treinadores de natação competitiva com formação acadêmica diferentes foram responsáveis por avaliar a técnica da braçada do nado crawl de 44 nadadores por meio de vídeo. Cada nadador realizou um percurso de 25m em velocidade confortável tendo seu deslocamento gravado nos planos lateral e frontal, ambos submersos e fora d'água, nos 10 m finais da piscina. No percurso de filmagem os nadadores não realizaram a respiração lateral. Somente o movimento realizado pelo braço direito foi foco de observação dos avaliadores e com base em uma lista de verificação. Após as filmagens os avaliadores participaram de três etapas: na primeira etapa houve uma intervenção para padronização dos critérios de observação e de avaliação. Na segunda etapa testou-se a concordância inter-avaliadores e, na terceira, a concordância intra-avaliador. Na segunda etapa do estudo a concordância variou de pequeno a baixa (k=0,08 e k=0,38). Na terceira etapa alguns avaliadores apresentaram concordância pobre e baixa (k=-0,13 e k=0,35), enquanto outros apresentaram concordância entre razoável e praticamente perfeita (k=0,64 e k=0,87). A partir dos resultados apresentados concluiu-se que a proposta de intervenção não surtiu o efeito desejado de padronização dos critérios de observação e avaliação entre os avaliadores.

ABSTRACT This study aimed to assess the effect of standardizing observation and rating criteria for the front crawl stroke technique on inter- and intra-rater reliability in order to propose an observation list. Two teachers and two competitive swimming coaches with different academic backgrounds were responsible for evaluating the front crawl stroke technique of 44 swimmers using video. Each swimmer completed a 25m course at a comfortable speed, having their displacement recorded in the lateral and frontal planes, both submerged and out of water, in the final 10 m of the pool. Throughout the recording, the swimmers did not breath laterally. Only the movement performed by the right arm was the raters' focus of observation and was based on a checklist. After the shooting, the raters participated in three stages: in the first stage, there was an intervention to standardize the observation and rating criteria; inter-rater agreement was tested in the second stage, while intra-rater agreement was obtained in the third. In the second stage of the study, the agreement ranged from small to low (k=0.08 and k=0.38). In the third stage, some raters showed poor and low agreement (k=-0.13 and k=0.35), while others showed agreement between reasonable and virtually perfect (k=0.64 and k=0.87). From the results presented, it was concluded that the intervention proposal did not have the desired effect of standardizing the observation and rating criteria among the raters.

Os desamparos da maternidade em um contexto de vulnerabilidade social / The helplessness of motherhood in a context of social vulnerability / El desamparo de la maternidade en un contexto de vulnerabilidad social

Algumas mães, mesmo acompanhadas de um parceiro, desempenham solitariamente múltiplos papéis, cuidando da rotina de casa, do trabalho e, precariamente, de si mesmas. Com o objetivo de discutir a maternidade em um contexto de vulnerabilidade e suas implicações no estabelecimento da relação mãe e filhos, a partir de um caso, utilizou-se um método observacional psicanalítico inspirado no Método Bick de Observação, sendo uma pesquisa qualitativa. As observações foram realizadas considerando os três tempos: observação semanal, no mesmo dia e hora; relato da observação, de forma descritiva e implicada; e, seminário de supervisão, para discussão das observações. Evidenciou-se o desamparo sentido por essa mulher-mãe que, apesar da presença da família e do esposo, não recebia o apoio necessário. Sua exaustão, oriunda do desamparo, resultava em perda de controle emocional em relação aos filhos. Ressalta-se o valor do Método Bick de Observação ao possibilitar um olhar sensível à maternidade

Some mothers, even when joined by a partner, end up playing multiple roles alone, taking care of the household chores, their work lives and, precariously, of themselves. In order to discuss motherhood in a context of vulnerability and its implications in the establishing of the relationship between a mother and her children, based on a specific case, an psychoanalytic observational method inspired by the Bick Method of Observation was employed, being a qualitative research. The observations were carried out considering three tempos: weekly observation, on the same day and time; observation report, in an involved and descriptive way; and supervision seminar, to discuss the observations. It was made evident the helplessness experienced by this woman-mother, who, despite the presence of her husband and family, did not receive the necessary support. Her exhaustion, stemming from this helplessness, resulted in a loss of emotional control over her children. The value of the Bick Observation Method is highlighted, as it enables a sensitive outlook towards motherhood

Algunas madres, incluso las acompañadas de pareja, desempeñan múltiples papeles solas, cuidando la rutina de la casa, el trabajo y, precariamente, ellas mismas. Para discutir la maternidad en un contexto de vulnerabilidad y sus implicaciones para el establecimiento de la relación entre las madres y sus hijos, a partir de un caso, se utilizó un método observacional psicoanalítico inspirado en el Método de Observación Bick, haciendo de esta una investigación cualitativa. Las observaciones se realizaron considerando los tres tiempos: observación semanal, en el mismo día y hora; informe de la observación, de forma descriptiva y implícita; y, seminario de supervisión, para discutir las observaciones. Se hizo evidente el desamparo que siente esta mujer-madre, quien, a pesar de la presencia de su familia y esposo, no recibe el apoyo necesario. Su agotamiento, derivado del desamparo, resultó en una pérdida del control emocional sobre sus hijos. Se destaca el valor del método de observación de Bick, que permite una mirada sensible a la maternidad

Uso del método de observación: una propuesta de aplicación al análisis de estrategias de resolución de problemas en niños con discapacidad / Use of observational method: a proposal for application to the analysis of problem-solving strategies in children with disabilities

El presente trabajo se ocupa de evaluar posibilidades del método de observación aplicado al análisis de estrategias de resolución de problemas en niños con discapacidad mediante juegos y tareas estructuradas. El marco teórico de referencia de esta contribución está representado por la teoría de la resolución de problemas, que contiene los principales procesos que intervienen en la gestión de los problemas y que nosotros aplicamos al desarrollo cognitivo y metacognitivo atípico. Junto con tres tareas diferentes estructuradas(Torre de Hanoi, Tetris y Bloques de construcción), usamos dos listas de comportamientos para codificar estrategias de resolución de problemas adoptadas por niños y/o adolescentes con desarrollo atípico. La aplicación de este tipo de observación con el uso de listas de comportamientos podría ser útil para crear en relación entre la investigación cualitativa y cuantitativa para mejorar el conocimiento de las estrategias de resolución de problemas y competencias metacognitivas en niños desarrollados atípicos(AU)

This paper is concerned with evaluating the possibilities of the observational method applied to the analysis of problem-solving strategies in children with disabilities through structured tasks. The theoretical framework of reference for this contribution is represented by the theory of problem-solving, containing the main processes involved in problem management,which we apply to atypical cognitive and metacognitive development. Together with three different structured tasks (Tower of Hanoi, Tetris, and Building Blocks), we used two lists of behaviors to code problem-solving strategies adopted by children and/or adolescents with atypical development. The application of this type of observation with the use of lists of behaviors could be useful to create a link between qualitative and quantitative research to improve the knowledge of problem-solving strategies and metacognitive competencies in atypically developed children(AU)

Agujero Timpánico bilateral. Análisis de caso desde la literatura / Bilateral tympanic hole. Case analysis from the literature

La pared del conducto auditivo externo (CAE) parte de la formación del hueso timpánico; integrándose posteriormente a la porción petrosa del hueso temporal. El agujero timpánico o foramen de Huschke corresponde a un defecto en la osificación en donde existe fusión incompleta de porciones anteriores y posteriores del anillo timpánico dejando una abertura que comunica el CAE hacia anterior. Su presencia es normal hasta los 5 años de edad, tiempo en que se debiese obliterar. Su incidencia es baja (3-24%), pero la persistencia en adulto, conlleva sintomatología inespecífica caracterizada por otalgia, dolor en articulación temporomandibular (ATM), tinnitus, hipoacusia o manifestaciones complejas como descarga salival en CAE durante la masticación. Clínicamente puede complicar procedimientos de infiltración y artroscopias de ATM. Rara vez ocasiona, en pacientes mayores de 50 años, herniación de la cabeza del cóndilo mandibular. Su diagnóstico puede ser clínico por medio de otoscopia, donde se observa protuberancia de tejido en pared anterior del CAE, que aumenta de tamaño con la boca cerrada. También puede ser imagenológico con una tomografía computarizada. El tratamiento incluye desde medidas conservadoras para manejo del dolor e inflamación, hasta quirúrgicas con la implantación de injertos, placas o prótesis para cerrar la estructura o para reemplazar el cóndilo mandibular. El presente estudio pretende aportar incidencia dentro del área de estudio. Se analiza por observación directa, cráneo seco, completo, masculino, edad entre 12 a 15 años (según morfología del cóndilo mandibular y erupción dental). Se observa agujero de Huschke, bilateral, ambos permeables de diámetro 4 mm en ambos casos, determinados con regla milimetrada. La relevancia del defecto se asocia a la práctica clínica de otorrinolaringólogos, cirujanos maxilofaciales y odontólogos, ya sea como diagnóstico diferencial asociado a los síntomas inespecíficos, como para procedimientos más invasivos en la zona tales como infiltraciones o artroscopias de ATM

The wall of the external auditory canal (EAC) starts from the formation of the tympanic bone; later it is integrated to the petrous portion of the temporal bone. The tympanic foramen or foramen of Huschke corresponds to a defect in ossification where there is incomplete fusion of the anterior and posterior portions of the tympanic ring leaving an opening that communicates the EAC to its anterior aspect. Its presence is normal until 5 years of age, when it should be absolutely obliterated. Its incidence is low (3-24%), but its persistence in adults leads to non specific symptoms characterized by otalgia, pain in the temporomandibular joint (TMJ), tinnitus, hearing loss, or complex manifestations such as salivary discharge in the CAE during mastication. Clinically, it may complicate TMJ infiltration and arthroscopy procedures. It rarely causes herniation of the mandibular condyle head in patients older than 50 years. Its diagnosis can be clinical by means of otoscopy, where tissue protrusion is observed in the anterior wall of the CAE, which increases in size when the mouth is closed. It can also be imaging with computed tomography. Treatment includes from conservative measures to treat pain and inflammation, to surgical measures with the implantation of grafts, plates or prosthesis to close the structure or to replace the mandibular condyle. The present study aims to provide incidence within the study area. It is analyzed by direct observation, dry skull, complete, male, age between 12 to 15 years (according to mandibular condyle morphology and dental eruption). Huschke's foramen was observed, bilateral, both permeable, diameter 4mm in both cases, determined with a millimeter ruler. The relevance of the defect is associated with the clinical practice of otolaryngologists, maxillofacial surgeons and dentists, either as a differential diagnosis associated with nonspecific symptoms, or for more invasive procedures in the area such as infiltrations or TMJ arthroscopies.

Ambiente de ensino-aprendizagem na formação inicial universitária / Teaching-learning environment in initial university training in physical education

ABSTRACT This study aimed to analyze the perceptions of university Physical Education students at different progression levels in the programs regarding the teaching-learning environment in the initial training. In total, 273 students (Bachelor's program n = 150; Licentiate program n = 123) from the Licentiate Program in Physical Education of a public university in Santa Catarina, Brazil, participated in this study, responding to the adapted version of the Assessment Questionnaire of the Perceived Environment in the Initial Training in Physical Education. The Chi-square test was used to analyze the associations between the student progression levels in the programs and their perceptions about the initial training environment. The results indicated the predominance of practical classes/experiences and written theoretical evaluations, especially in the initial phases. The infrequent observation experiences and learning through practice or observation were the assumed roles, made evident primarily in the final semesters. Although the students perceived themselves as active regarding their participation levels, they indicated that the professors are the ones responsible for making the decisions. It is concluded that the initial training in Physical Education requires reconfiguring certain teaching-learning practices to increase student involvement and responsibility for their own training process.

RESUMO Objetivou-se analisar as percepções de estudantes universitários de Educação Física em distintos níveis de progressão no curso, sobre o ambiente de ensino-aprendizagem na formação inicial. Participaram 273 estudantes (Bacharelado n=150; Licenciatura n=123) do curso de licenciatura em Educação Física de uma universidade pública de Santa Catarina, Brasil, os quais responderam à versão adaptada do Questionário de Avaliação do Ambiente Percebido da Formação Inicial em Educação Física. O teste Qui-quadrado foi utilizado para analisar as associações entre o nível de progressão discente nos cursos e suas percepções sobre o ambiente de formação inicial. Os resultados indicaram a predominância de aulas/vivências práticas e de avaliações teóricas escritas, especialmente nas fases iniciais. As experiências poucos frequentes de observação, e o aprendizado pela prática ou por observação foi o papel assumido, especialmente evidenciados nos semestres finais. Apesar de os estudantes terem se percebido ativos quanto ao seu nível de participação, indicaram que os professores são os principais responsáveis por tomar as decisões. Conclui-se que a formação inicial em Educação Física necessita reconfigurar determinadas práticas de ensino-aprendizagem para aumentar o envolvimento e a responsabilidade discentes pelo próprio processo formativo.

Single session of action observation in choice reaction time in healthy children

Abstract Aim: Learning by action observation (AO) is a fundamental cognitive ability existing from birth either in live or in the video. However, the specific AO training, in live or in the video, can influence decision making and motor planning in healthy children? This study aimed to evaluate if a single session of both practices (live and video) modifies the choice reaction time during reaching tasks in healthy children. Methods: This is a cross-sectional and randomized study with 22 children aged 6 to 8 years. We measured the choice reaction time (CRT) by electromyography at baseline and after both practices. Data were analyzed using Friedman and posthoc Dunn non-parametric tests for each age group individually as well as all ages combined. Kurtosis analysis was performed to assess data variability. Results: Significant decrease in CRT was observed after action observation in the video in 8-year-olds. Also, we observed choice reaction time variability reduction in 8-year-olds after both practices compared to that at baseline. Conclusion: A decrease in CRT was observed after the single session of action observation in the video in 8-year-olds. Additionally, there was a reduced variability in CRT after performing both practices in the same age group.

Crawl technique observation sheet for beginning swimmers: an evaluation proposal for swimming teachers

Abstract Aims: This study aimed to present a technical evaluation proposal for the crawl stroke that can be used with large groups of swimmers, based on an observation sheet. Methods: Fifteen healthy university students aged between 18 and 30 years were chosen to participate in the study. The subjects were recorded swimming at a distance of 50 meters using the crawl technique at a comfortable and self-determined speed. The recordings simulated docent observation capacity. Five swimming teachers were selected to evaluate the proposed checklist and the subjects' technique. An observation sheet was created based on references present in literature containing ten items that are considered fundamental for swimming movements. The study was divided into (i) checklist validation, (ii) intra-evaluator consistency, and (iii) inter-evaluator consistency. Results: The proposed checklist fulfilled the validity criteria, with intra-evaluator consistency varying between reasonable and substantial, with k varying between 0.36 and 0.73 respectively, while inter-evaluator consistency was deemed reasonable (k = 0.24). Conclusion: According to the results that were obtained, the suggested list is valid and adequate for what it proposes to do.

Cost-effectiveness analyses demonstrate that observation is superior to sentinel lymph node biopsy for postmenopausal women with HR + breast cancer and negative axillary ultrasound.

PURPOSE: To evaluate the cost-effectiveness of axillary observation versus sentinel lymph node biopsy (SLNB) after negative axillary ultrasound (AUS). In patients with clinical T1-T2 N0 breast cancer and negative AUS, SLNB is the current standard of care for axillary staging. However, SLNB is costly, invasive, decreasing in importance for medical decision-making, and is not considered therapeutic. Observation alone is currently being evaluated in randomized clinical trials, and is thought to be non-inferior to SLNB for patients with negative AUS. METHODS: We performed cost-effectiveness analyses of observation versus SLNB after negative AUS in postmenopausal women with clinical T1-T2 N0, HR+/HER2- breast cancer. Costs at the 2016 price level were evaluated from a third-party commercial payer perspective using the MarketScan® Database. We compared cost, quality-adjusted life years (QALYs), and net monetary benefit (NMB). Multiple sensitivity analyses varying baseline probabilities, costs, utilities, and willingness-to-pay thresholds were performed. RESULTS: Observation was superior to SLNB for patients with N0 and N1 disease, and for the entire patient population (NMB in US$: $655,659 for observation versus $641,778 for SLNB for the entire patient population). In the N0 and N1 groups, observation incurred lower cost and was associated with greater QALYs. SLNB was superior for patients with > 3 positive lymph nodes, representing approximately 5% of the population. Sensitivity analyses consistently demonstrated that observation is the optimal strategy for AUS-negative patients. CONCLUSION: Considering both cost and effectiveness, observation is superior to SLNB in postmenopausal women with cT1-T2 N0, HR+/HER2- breast cancer and negative AUS.

Cortical Observation by Synchronous Multifocal Optical Sampling Reveals Widespread Population Encoding of Actions.

To advance the measurement of distributed neuronal population representations of targeted motor actions on single trials, we developed an optical method (COSMOS) for tracking neural activity in a largely uncharacterized spatiotemporal regime. COSMOS allowed simultaneous recording of neural dynamics at ∼30 Hz from over a thousand near-cellular resolution neuronal sources spread across the entire dorsal neocortex of awake, behaving mice during a three-option lick-to-target task. We identified spatially distributed neuronal population representations spanning the dorsal cortex that precisely encoded ongoing motor actions on single trials. Neuronal correlations measured at video rate using unaveraged, whole-session data had localized spatial structure, whereas trial-averaged data exhibited widespread correlations. Separable modes of neural activity encoded history-guided motor plans, with similar population dynamics in individual areas throughout cortex. These initial experiments illustrate how COSMOS enables investigation of large-scale cortical dynamics and that information about motor actions is widely shared between areas, potentially underlying distributed computations.

Identification and evaluation of observational measures for the assessment and/or monitoring of level of consciousness in adult palliative care patients: A systematic review for I-CAN-CARE.

BACKGROUND: The use of observational measures to assess palliative care patients' level of consciousness may improve patient care and comfort. However, there is limited knowledge regarding the validity and reliability of these measures in palliative care settings. AIM: To identify and evaluate the psychometric performance of observational level of consciousness measures used in palliative care. DESIGN: Systematic review; PROSPERO registration: CRD42017073080. DATA SOURCES: We searched six databases until November 2018, using search terms combining subject headings and free-text terms. Psychometric performance for each identified tool was appraised independently by two reviewers following established criteria for developing and evaluating health outcome measures. RESULTS: We found 35 different levels of consciousness tools used in 65 studies. Only seven studies reported information about psychometric performance of just eight tools. All other studies used either ad hoc measures for which no formal validation had been undertaken (n = 21) or established tools mainly developed and validated in non-palliative care settings (n = 37). The Consciousness Scale for Palliative Care and a modified version of the Richmond Agitation-Sedation Scale received the highest ratings in our appraisal, but, since psychometric evidence was limited, no tool could be assessed for all psychometric properties. CONCLUSION: An increasing number of studies in palliative care are using observational measures of level of consciousness. However, only a few of these tools have been tested for their psychometric performance in that context. Future research in this area should validate and/or refine the existing measures, rather than developing new tools.

La observación. Primer eslabón del método clínico / Observation. First step of the clinical method

Introducción: la observación es la base del conocimiento del mundo y de la actividad científica. Objetivo: destacar la importancia de la observación como parte del método clínico para arribar al diagnóstico en un proceso salud enfermedad y poder decidir la terapéutica adecuada. Desarrollo: el método de observación es un proceso de descomposición-recomposición de informaciones obtenidas mediante la percepción, según los fines científicos establecidos en los modos de observación construidos. Se señala que es un proceso activo y organizado en el tiempo, en el cual se considera, un conjunto de fenómenos que pueden ser analizados. Conclusiones: la observación es la primera etapa del método clínico porque es de donde parte la obtención de información, tanto por lo que dice el enfermo como por lo que se puede observar mediante la inspección. Quiere decir que, no solo la información se vincula con la comunicación verbal, sino con formas no verbales como la inspección, y de esa forma se llega a acopiar datos sobre lo que ya puede ser explícito o general o sobre aspectos más particulares o específicos(AU)

Introduction: observation is the basis of knowledge of the world and of scientific activity. Objective: to emphasize the importance of observation as part of the clinical method to arrive at the diagnosis in a disease health process and to be able to decide the appropriate treatment. Development: the observation method is a process of decomposition-recomposition of information obtained through perception, according to the scientific purposes established in the modes of observation constructed. It is pointed out that it is an active and organized process over time, in which it is considered, a set of phenomena that can be analyzed. Conclusions: observation is the first stage of the clinical method because it is from where the information is obtained, both by what the patient says and by what can be observed through inspection. It means that not only information is linked to verbal communication, but also to non-verbal forms such as inspection, and in this way it is possible to collect data on what can already be explicit or general or on more specific or specific aspects(AU)

Microwave ablation: A new technique for the prophylactic management of idiopathic recurrent epistaxis.

OBJECTIVE: The objective of this study was to compare the re-bleeding of idiopathic recurrent epistaxis with no definite bleeding site treated with either prophylactic microwave ablation (MWA) or continuous observation. STUDY DESIGN: Case series with chart review. SUBJECTS AND METHODS: 61 patients with idiopathic recurrent epistaxis but no definite bleeding sites in the first operation were assigned to prophylactic MWA group (n = 39) and continuous observation group (n = 22). Patients in prophylactic MWA group were given prophylactic MWA at the common bleeding sites. Patients in continuous observation group were only observed in the ward. The bleeding sites, re-bleeding and complications were evaluated during 3 months follow-up period. RESULTS: Rebleeding was experienced by 7 of the patients (17.9%) who were treated with prophylactic MWA whereas, 13 of the patients (59.1%) who used continuous observation had rebleeding. The rebleeding rate for patients undergoing prophylactic MWA group was lower than that for the observation-only group (p < 0.01). All the ablations were completed for the patients with known bleeding site within 1-2 min. These patients only had the complain of slight postoperative pain, no serious complications (including nasal adhesion, crust, septal perforation, etc.) were found in the follow-up period. CONCLUSIONS: MWA is a simple, convenient, rapid, and definite hemorrhage control method with minimally invasive therapeutic technique. Prophylactic MWA at the common bleeding sites helps to significantly reduce the rate of rebleeding in patients in whom no definite bleeding sites have been identified.

Paediatric Colonoscopy Direct Observation of Procedural Skills: Evidence of Validity and Competency Development.

INTRODUCTION: The paediatric series of direct observation of procedural skills (DOPS) were introduced into the UK national endoscopy training curriculum in 2016, but lack validity evidence. We aimed to present validity evidence for paediatric colonoscopy DOPS and study competency development in a national trainee cohort. METHODS: This prospective UK-wide study analysed formative paediatric colonoscopy DOPS which were submitted to the e-Portfolio between 2016 and 2018. Item, domain, and average DOPS scores were correlated with the overall DOPS rating to evidence internal structure validity. Overall DOPS ratings were compared over lifetime procedure count to demonstrate learning curves (discriminant validity). Consequential validity was founded on receiver operating characteristic curve analyses. RESULTS: A total of 203 DOPS assessments were completed for 29 trainees from 11 UK training centres. Internal structure validity was provided through item-total correlation analyses. DOPS scores positively correlated with trainee seniority (P < 0.001) and lifetime procedure count (P < 0.001). Competency acquisition followed the order of: "preprocedure," "postprocedure," "endoscopic nontechnical skills," "management," "procedure" domains, followed by overall DOPS competency, which was achieved in 81% of the cohort after 125 to 149 procedures. Mean DOPS scores could be used to predict overall procedure competence (area under receiver operating characteristic curve 0.969, P < 0.001), with a mean score of 3.9 demonstrating optimal sensitivity (93.5%) and specificity (87.6%). CONCLUSIONS: This study provides validity evidence supporting the use of paediatric colonoscopy DOPS as an in-training competence assessment tool. DOPS may also be used to measure competency development and benchmark performance during training, which may be of value to trainees, trainers, and training programmes.

Observação da interação professor-aluno no jardim de infância: O Teacher-Pupil Observation Tool / Observation of teacher-student interaction in preschool: the teacher-pupil observation tool / Observación de la interacción profesor-alumno en la educación infantil: el teacher-pupil observation tool

Este estudo teve como objetivo apresentar a versão portuguesa do Teacher-Pupil Observation Tool (T-POT), no que diz respeito ao acordo e fidedignidade entre observadores e às categorias de comportamentos observadas nos professores na sua utilização em contexto pré-escolar. Três observadores receberam treinamento na cotação de 11 categorias de comportamentos do professor do T-POT. Posteriormente, 65 professoras de jardim de infância foram observadas durante 25 minutos, numa situação de interação nas suas salas com um pequeno grupo de crianças. Obteve-se uma média de acordo entre observadores de 74% nas sessões de treinamento e coeficientes de correlação intraclasse de 0,90-0,99. Os resultados indicam que as categorias do T-POT mais utilizadas pelas professoras nas suas interações com as crianças são questões, confirmações e ordens. A discussão salienta as implicações para a prática e a pesquisa da utilização de medidas de observação na avaliação da interação professor-aluno nas salas de jardim de infância. (AU)

The purpose of this study was to present the Portuguese version of the Teacher-Pupil Observation Tool (T-POT), in terms of agreement and reliability among observers and the categories of behaviors observed in teachers when used in preschool setting. Three observers were trained in scoring 11 T-POT teacher's behavior categories. Subsequently, 65 preschool teachers were observed with T-POT during 25 minutes, while interacting in their classrooms with a small group of children. A mean of 74% of agreement was reached between observers for the training sessions and intraclass correlation coefficients of 0,90-0,99. The results indicate that the T-POT categories most used by teachers in their interactions with children are questions, acknowledgments and commands. The discussion highlights the implications for practice and research on the use of observation measures in the assessment of teacher-student interaction in preschool classrooms. (AU)

An Additional 30-s Observation of the Right-Sided Colon with Narrow Band Imaging Decreases Missed Polyps: A Pilot Study.

INTRODUCTION: Previous narrow-band imaging (NBI) was dark and reported not to be useful for polyp detection. In this study, we analyzed the efficacy of an additional 30-s observation of the right-sided colon with the recent bright high-resolution NBI. METHODS: We enrolled patients undergoing colonoscopy from February 2015 to May 2017 in two institutions. All procedures were performed with the latest system (EVIS LUCERA ELITE, Olympus). The cecum and ascending colon were first observed with white light imaging (WLI) in both the NBI and WLI group. Then, the colonoscope was re-inserted, and the cecum and ascending colon were observed for an additional 30 s. In this second observation, NBI was performed for the first 130 patients in the NBI group and WLI for the next 130 in the WLI group. The number of adenoma and sessile serrated polyps (ASPs) in the second observation were examined in both groups. According to our initial pilot study, the sample size was estimated at 126. RESULTS: In the first observation, the number of ASPs was 72 in the NBI group and 72 in the WLI group (p = 1.0). In the second observation, the number of ASPs was 23 in the NBI group and 10 in the WLI group (p = 0.02). The polyp and adenoma detection rates in the second observation were 16.2% and 12.3% in the NBI group and 7.7% (p = 0.03) and 6.2% (p = 0.09) in the WLI group. CONCLUSIONS: The additional 30-s observation with recent NBI decreased missed polyps in the right-sided colon.

Observational Surveillance Approach to Detect Novel Work-Related Diseases and Hazards: An Application to a Belgian Occupational Health and Safety Database.

OBJECTIVES: Rapid changes in working conditions give rise to new occupational health risks. We applied the Spectrosome approach, a network-based analysis, to investigate associations between disease and multiple occupational exposures. METHODS: We investigated work and health's associations in a specific sector: the agricultural sector and for a specific and frequent health complaint: sore throat; using PRECUBE dataset of the Belgian Occupational Health and Safety, containing 381.615 occupational health observations. We compared the results of the spectrosome with classic frequency analyses. RESULTS: Spectrosome approach reports more significant signals of multiple associations of agents compare to the frequency analysis. CONCLUSION: This difference justifies the usefulness of taking into account the multiplicity of causes leading to a health event, which is a clear asset of the Spectrosome method.
