Introduction: Though patients with nanophthalmos frequently endure decreased quality of vision with contact lenses or spectacles, refractive surgery is generally an inadequate alternative due to the associated high refractive error. A refractive lens exchange (RLE) is an alternative option but is technically challenging, requiring accuracy in biometry measurements and procedures. Case Presentation: This case discusses a 27-year-old female with nanophthalmos (axial lengths 17.6 mm and 17.4 mm, right and left eyes, respectively) who underwent a femtosecond laser-assisted (FLA) RLE with simultaneous implantation of a monofocal and a Sulcoflex trifocal (Rayner, Britain) lens in each eye. Preoperative cycloplegic refraction was +11.50/−0.75 × 145 and +12.00/−1.00 × 35 in the RE and LE, respectively. Best-corrected visual acuity (BCVA) at distance and near in the RE and LE was 6/7.5 and J1, 6/8.5 and J2, respectively. Uncorrected visual acuity (UCVA) was >6/120 and >J14 for each eye. FLA RLE was performed in the RE, then in the LE 2 weeks later. In each eye, a monofocal (44.0 D, RE, and LE) and a Sulcoflex trifocal lens (both implants, Rayner, Britain) were implanted in one procedure. Distance and near UCVA measured 6 weeks post-op RE and 1-month post-op LE at 6/8.5 and J1 in the RE, 6/10 and J1 in the LE. The RE and LE refraction and BCVA were +0.50/−1.00 × 115, 6/7.5, and plano/−1.00 × 55, 6/8.5, respectively. The post-op outcomes were uneventful. Conclusion: A single procedure concurrently implanting a monofocal and Sulcoflex trifocal intraocular lens in nanophthalmic eyes resulted in an excellent UCVA. This procedure can be considered esthetic and reconstructive as it significantly improves patient appearance and function.

Introduction: The traditional Japanese herbal medicine hochuekkito (TJ-41) has been reported to ameliorate systemic inflammation and malnutrition in patients with chronic obstructive pulmonary disease (COPD). TJ-41 has also been known to have preventive effects against influenza virus infection. However, its role in the acute exacerbation of COPD (AECOPD) remains to be elucidated. Our previous study established a murine model of viral infection-associated AECOPD that was induced by intratracheal administration of porcine pancreatic elastase (PPE) and polyinosinic-polycytidylic acid [poly(I:C)]. Here, we used this model and investigated the effects of TJ-41 in AECOPD. Methods: Specific pathogen-free C57BL/6J mice were used. A COPD model was induced by treating mice intratracheally with PPE on day 0. To generate the murine model of AECOPD, poly(I:C) was administered intratracheally following PPE treatment on days 22–24. Mice were sacrificed and analyzed on day 25. Mice were fed a diet containing 2% TJ-41 or a control diet. Results: Daily oral intake of TJ-41 significantly decreased the numbers of neutrophils and lymphocytes in the bronchoalveolar lavage fluid (BALF), which was accompanied by decreased transcripts of CXC chemokines involved in neutrophil migration, viz., Cxcl1 and Cxcl2, in whole lung homogenates and reduced Cxcl2 concentration in BALF. Conclusion: This study demonstrates the anti-inflammatory effects of TJ-41 in a mouse model of AECOPD, suggesting the effectiveness of TJ-41 for the management of COPD. Clinical investigations evaluating the therapeutic efficacy of TJ-41 in AECOPD would be meaningful.

Große Sprachmodelle (Large Language Models, LLMs) sind Tools der künstlichen Intelligenz (KI), die speziell für die Verarbeitung und Erzeugung von Text trainiert sind. LLMs erregten erhebliche öffentliche Aufmerksamkeit, nachdem ChatGPT von OpenAI im November 2022 öffentlich zugänglich gemacht wurde. LLMs können Fragen beantworten, Texte zusammenfassen, paraphrasieren und übersetzen, und zwar auf einer Ebene, die von menschlichen Fähigkeiten kaum zu unterscheiden ist. Die Möglichkeit, aktiv mit Modellen wie ChatGPT zu interagieren, macht LLMs zu attraktiven Tools in verschiedenen Bereichen, einschließlich der Medizin. Diese Modelle haben zwar das Potenzial, medizinisches Wissen zu demokratisieren und den Zugang zur Gesundheitsversorgung zu erleichtern, sie könnten jedoch aufgrund mangelnder Rechenschaftspflicht und Transparenz ebenso Fehlinformationen verbreiten und wissenschaftliches Fehlverhalten verschlimmern. In diesem Artikel geben wir einen systematischen und umfassenden Überblick über die Potenziale und Grenzen von LLMs in der klinischen Praxis, der medizinischen Forschung und der medizinischen Ausbildung.

Authors: An Kun , Chen Chun , Dong Meijuan , Chen Wei , Cao Yongjun
Published: February 2024

Introduction: Post-thrombectomy intraparenchymal hyperdensity (PTIH) in patients with acute ischemic stroke is a common CT sign, making it difficult for physicians to distinguish intracerebral hemorrhage in the early post-thrombectomy period. The aim of this study was to develop an effective model to differentiate intracerebral hemorrhage from contrast extravasation in patients with PTIH. Methods: We retrospectively collected information on patients who underwent endovascular thrombectomy at two stroke centers between August 2017 and January 2023. A total of 222 patients were included in the study, including 118 patients in the development cohort, 52 patients in the internal validation cohort, and 52 patients in the external validation cohort. The nomogram was constructed using R software based on independent predictors derived from the multivariate logistic regression analysis, including clinical factors and CT texture features extracted from hyperdense areas on CT images. The performance and accuracy of the derived nomogram were assessed by the area under the receiver operating characteristic curve (AUC-ROC) and calibration curves. Additionally, decision curve analysis was conducted to appraise the clinical utility of the nomogram. Results: Our nomogram was derived from two clinical factors (ASPECT score and onset to reperfusion time) and two CT texture features (variance and uniformity), with AUC-ROC of 0.943, 0.930, and 0.937 in the development, internal validation, and external validation cohorts, respectively. Furthermore, the calibration plot exhibited a strong agreement between the predicted outcome and the actual outcome. In addition, the decision curve analysis revealed the clinical utility of the nomogram in accurately predicting hemorrhage in patients with PTIH. Conclusion: The developed nomogram, based on clinical factors and CT texture features, proves to be effective in distinguishing intracerebral hemorrhage from contrast extravasation in patients with PTIH.
Mobile Health: Potenziale und Herausforderungen in der medizinischen Versorgung
Authors: Link Hartmut
Published: February 2024

Background: Mobile health (mhealth) is gaining interest, with mobile devices and apps being ever more available among medical facilities and patients. However, in the field of radiation oncology, the medical benefits of mhealth apps are still underexplored. As an additional approach to patient care during radiotherapy, we designed a mobile treatment surveillance app based on patient-reported outcomes. Objective: We aimed to examine the feasibility of app-based treatment surveillance in patients undergoing radiotherapy (RT). Alongside technical practicability and acceptance, we assessed patient satisfaction and quality of life during treatment. Methods: This prospective single-center study was performed at Heidelberg University Hospital between August 2018 and January 2020. During RT we measured patients' quality of life, symptoms, and treatment satisfaction. Respective questionnaires (EORTC QLQ-C30 with diagnosis-specific modules, RAND PSQ-18) were presented to patients via a mobile app running on a designated tablet device. The primary endpoint was determined by the fraction of patients who completed at least 80% of the items. Secondary endpoints were disease-related quality of life and patient satisfaction. Results: A total of 49 cancer patients (14 breast, 13 pelvic, 12 lung, 10 prostate) were eligible for analysis. 79.6% (95% confidence interval: 66.4-88.5%; n = 39) of all patients completed at least 80% of the items received by the mobile app. A mean of 227.5 ± 48.25 questions were answered per patient. Breast cancer patients showed the highest rate of answered questions, with 92.9% (n = 13) completing at least 80% of the items.
Cholangioskopie im Fokus: Künstliche Intelligenz verbessert Genauigkeit und Effizienz der Diagnoseverfahren
Authors: Homayounfar Kia
Published: February 2024

Background: We aimed to develop a convolutional neural network (CNN) model for detecting neoplastic lesions during real-time digital single-operator cholangioscopy (DSOC) and to clinically validate the model through comparisons with DSOC expert and nonexpert endoscopists. Methods: In this two-stage study, we first developed and validated CNN1. Then, we performed a multicenter diagnostic trial to compare four DSOC experts and nonexperts against an improved model (CNN2). Lesions were classified into neoplastic and non-neoplastic in accordance with Carlos Robles-Medranda (CRM) and Mendoza disaggregated criteria. The final diagnosis of neoplasia was based on histopathology and 12-month follow-up outcomes. Results: In stage I, CNN2 achieved a mean average precision of 0.88, an intersection over the union value of 83.24 %, and a total loss of 0.0975. For clinical validation, a total of 170 videos from newly included patients were analyzed with the CNN2. Half of cases (50 %) had neoplastic lesions. This model achieved significant accuracy values for neoplastic diagnosis, with a 90.5 % sensitivity, 68.2 % specificity, and 74.0 % and 87.8 % positive and negative predictive values, respectively. The CNN2 model outperformed nonexpert #2 (area under the receiver operating characteristic curve [AUC]-CRM 0.657 vs. AUC-CNN2 0.794, P < 0.05; AUC-Mendoza 0.582 vs. AUC-CNN2 0.794, P < 0.05), nonexpert #4 (AUC-CRM 0.683 vs. AUC-CNN2 0.791, P < 0.05), and expert #4 (AUC-CRM 0.755 vs. AUC-CNN2 0.848, P < 0.05; AUC-Mendoza 0.753 vs. AUC-CNN2 0.848, P < 0.05).

Authors: Crouch Elizabeth , Yell Nick , Herbert Laura , Browne Teri , Hung Peiyin
Published: February 2024

Introduction: Rural areas face significant disparities in dialysis care compared to urban areas due to limited access to dialysis facilities, longer travel distances, and a shortage of healthcare professionals. The objective of this study was to conduct a national examination of rural-urban differences in quality of dialysis care offered across counties in the USA. Methods: Data were gathered from Medicare-certified dialysis facilities in 2020 from the Centers for Medicare and Medicaid Services website. To identify high-need counties, county-level estimated crude prevalence of diabetes in adults was obtained from the 2022 CDC PLACES data portal. Our analysis reviewed 3,141 counties in the USA. The primary outcome measured was whether the county had a dialysis facility. Among those counties that had a dialysis facility, additional outcomes were the average star rating, whether peritoneal dialysis was offered, and whether home dialysis was offered. Results: The type of services offered by dialysis facilities varied significantly, with peritoneal dialysis being the most commonly offered service (50.8%), followed by home hemodialysis (28.5%) and late-shift services (16.0%). These service availabilities are more prevalent in urban facilities than in rural facilities. The Centers for Medicare and Medicaid Services Five Star Quality ratings were quite different between urban and rural facilities, with 40.4% of rural facilities having a ranking of five, compared to 27.1% in urban. Conclusion: The majority of rural counties lack a single dialysis facility. Counties with high rates of chronic kidney disease, diabetes, and blood pressure, deemed high need, were less likely to have a highly rated dialysis facility. The findings can be used to further inform targeted efforts to increase diabetes educational programming and design appropriate interventions to those residing in rural communities and high-need counties who may need it the most.

Objetivo: Traçar o perfil epidemiológico das três principais causas dos óbitos maternos ocorridos entre o período de 2015 a 2020 no Brasil. Métodos: Estudo descritivo, quantitativo, com dados coletados no Sistema de Informações sobre Mortalidade (SIM) do SUS relativos aos óbitos maternos por síndromes hipertensivas, síndromes hemorrágicas e infecções puerperais entre 2015-2020. As variáveis selecionadas foram: região, faixa etária, raça/cor, escolaridade, local de ocorrência do óbito, ano do óbito e momento da gravidez ou puerpério em que a morte ocorreu. Resultados: Houve um total de 3819 óbitos durante esse período, sendo as síndromes hipertensivas responsáveis por 54,6% dos óbitos, dentre os três grupos sindrômicos. No geral, houve mais óbitos no ano de 2015, na região Nordeste, em hospitais e durante o puerpério imediato e tardio, ou seja, em até 42 dias após o parto. Em relação às variáveis socioeconômicas, as mulheres pardas, entre 30-39 anos e com escolaridade entre 8-11 anos foram as mais acometidas. Conclusão: O estudo identificou grupos de risco para mortalidade materna que indicam vulnerabilidade social, como raça não-branca predominante, baixa escolaridade e região Nordeste. Dessa forma, torna-se necessário propor melhores condições de saúde para gestantes, além de identificar precocemente esses grupos mais afetados pela tríade de mortalidade materna citada acima, isto é, as síndromes hipertensivas, as síndromes hemorrágicas e as infecções puerperais, para elaborar campanhas de conscientização e reduzir a mortalidade materna.

O estudo teve como objetivo verificar e comparar os efeitos do treinamento de força (TF) controlado com pré-ativação muscular antagonista, durante 16 sessões, sobre a força muscular de membros inferiores e no desempenho funcional em idosos sedentários. Foram selecionados 56 idosos, de ambos os sexos, com média de 66,5 ± 4,5 anos. Os participantes foram divididos em 3 grupos: TF1 n=17, TF2 n=18 e GC n=21. Foram mensurados o índice de massa corpórea (IMC), percentual de gordura (%G) e os testes de força de 1 repetição máxima do quadríceps femoral (FQF), de sentar e levantar na cadeira, o Timed Up and Go (TUG) e a caminhada de seis minutos. O estudo demonstrou que o teste de 1RM não foram encontradas diferenças estaticamente significativa intergrupo no momento pré-intervenção, porém no momento pós-intervenção foram encontradas diferenças estatísticas significativas intergrupo. No teste 1RM quando comparados com o GC (TF1pré vs TF1pós – T = -3,746, p<0,001; TF2pré vs TF2pós - T = -3,537, p<0,001; GCpré vs GCpós - T = -3,753, p<0,001). Foi verificada diferença estatística significativa entre o grupo TF2 e GC TF2 e GC (H(2)= 6,276, p = 0,04 | U=96,5; z=-2,410, p=0,016). Para o teste sentar e alcançar, (TF1pré vs TF1pós – T = -3,337, p<0,001); TF2pré vs TF2pós - T = -2,442, p=0,015) ; GCpré vs GCpós - T = -2,935, p=0,003). Para o teste de 6 minutos, na análise intergrupo, os grupos apresentaram diferenças estatisticamente significativas no momento pré-intervenção. O treinamento de força com pré-ativação muscular antagonista em idosos melhora a força muscular e o desempenho funcional.

The aim of the present study was to analyze the effect of interset stretching in the heart rate variability and hemodynamic responses. The sample consisted of 8 trained men (23 ± 2.72 years, 1.74 ± 0.07 meters, 75.66 ± 10.85 kg). The lower limbs training protocol started with three sets of 10 maximal repetitions in the back squat and leg press exercises, with 1-minute rest between sets. After that, 7 sets of maximal repetitions were performed on the leg extension machine with 30 seconds interval between sets, using the first 20 seconds for passive stretching of the quadriceps muscles. Hemodynamic responses and autonomic modulation were obtained at rest, during the session and immediately after for 15 minutes post-session. Autonomic modulation was monitored by heart rate variability. Significant reductions during and after resistance training protocol were observed for RR intervals, RMSSD, pNN50, SDNN, 2LV%, 2UV%, LF and HF in comparison with basal levels. Meanwhile, 0V% presented significantly increases during and after experimental protocol. Lower LF/HF, LFnu and HFnu values was observed during protocol. Systolic blood pressure (SBP), mean blood pressure (MBP), heart rate (HR) and rate pressure product (RPP) were significantly higher after session. After 15 minutes, SBP, DBP, MBP, and RPP returned to near baseline values. The sympathetic activity increased during the protocol and post 15 minutes.

O objetivo do estudo foi monitorar a carga interna de treino em diferentes métodos de treinamento em jovens atletas de voleibol de praia. Participaram do estudo 16 atletas, sendo seis da categoria sub-15 e 10 da categoria sub-17. O estudo teve duração de seis semanas, com um total de 18 sessões de treinamento. Foram analisadas a percepção subjetiva de esforço (PSE) e o volume de treinamento em cada sessão dos protocolos experimentais. A intervenção foi realizada utilizando-se dos métodos analítico e situacional. A carga interna de treinamento reportada na semana três (p=0,008) e cinco (p=0,003) foram superiores ao da semana dois. Na comparação entre os métodos foi identificado maiores valores de carga interna na semana três no método situacional (p=0,016) em comparação ao método analítico. Conclui-se que a carga interna de treino dos atletas de voleibol de praia durante as seis semanas de treinamento foi similar entre os métodos analítico e situacional. Porém, quando as seis semanas foram divididas, observou-se na semana três que os atletas do método situacional reportaram maiores cargas internas de treino em comparação ao método analítico.

O objetivo do presente estudo foi investigar os níveis de aptidão física e fatores sociodemográficos em praticantes de Crossfit® na cidade de Maringá, PR. Estudo transversal no qual a amostra foi composta de 90 adultos, praticantes de Crossfit®, em locais credenciados à oferta da modalidade, localizados no município de Maringá, PR, com idade entre 20 a 59 anos, de ambos os sexos, praticantes do método no mínimo há três meses. O recrutamento ocorreu nos locais de prática selecionados para a pesquisa. Um questionário estruturado foi utilizado para avaliar o perfil sociodemográfico e de prática de Crossfit®. Posteriormente foram mensuradas as variáveis antropométricas, força de preensão manual, resistência muscular abdominal, teste de flexão de braços e teste de sentar e alcançar. Os dados foram analisados pelos testes Kolmogorov-Smirnov, Kruskal-Wallis e “U” de Mann-Whitney. Foi adotada a significância de p < 0,05. Os homens apresentaram valores superiores nos testes de preensão manual, abdominal, flexão de braços, circunferência de cintura, relação cintura-quadril e IMC, enquanto as mulheres apresentaram melhores resultados no teste de flexibilidade (p<0.05). Os sujeitos que praticam a menos de um ano demonstraram pior resultado no teste de abdominal do que os praticam há mais tempo, além de terem apresentado pior resultado no teste de flexão de braços (p<0,05). Os que praticam o Crossfit® no mínimo cinco vezes por semana apresentaram melhor resultado no teste de flexão de braço do que os menos vezes na semana (p<0,05). Concluiu-se que o tempo de prática e a frequência semanal podem ser fatores intervenientes na aptidão física dos praticantes de Crossfit®.

Published: February 2024

O objetivo deste estudo foi analisar a imagem corporal das atletas de ginástica rítmica de competição em Manaus. Os motivos para essa busca fundamentam-se no fato de a Ginástica Rítmica (GR) exigir um modelo específico de estrutura de forma corporal com influência dos fatores socioculturais, representando um estereótipo magro, longilíneo, com baixa massa corporal pernas maiores que o tronco, que não tenha músculos aparentes e que deve possuir grande flexibilidade. Como instrumentos, utilizamos a escala Contour Drawing Rating Scale (CDRS), e o questionário de satisfação com a imagem corporal de Lutter. As análises dos questionários obedeceram à metodologia recomendada pelos instrumentos, tendo como base uma escala de valores numéricos. Os resultados apontaram alto índice de insatisfação corporal pelas ginastas, entendendo-se que esses resultados são reflexos das exigências da modalidade que prioriza o padrão ideal como inegavelmente longilíneo magro e esguio, visto que o que está em jogo é um corpo essencialmente magro, gerando outros desdobramentos, principalmente em relação ao corpo das atletas amazonenses. Ao optar por esse esporte, assumem-se suas regras e as expectativas que elas pressupõem, interferindo, sobremaneira, na imagem corporal das atletas.
Tecnologia e esporte: o desenvolvimento dos aparelhos da Ginástica Artística e sua influência no Brasil
Authors: Bortoleto Marco Antonio Coelho
Published: February 2024

Como elemento constitutivo do esporte moderno e elo de ligação com a sociedade, a tecnologia consolidou-se como um relevante objeto de estudo. Sob o argumento do aprimoramento da funcionalidade dos equipamentos, do aumento da segurança e da optimização da performance, esse imbricado processo mediado pelos interesses econômicos e políticos, materializa-se num particular segmento da indústria e do comércio. Considerando que o desenvolvimento dos aparelhos da Ginástica Artística vem modificando substancialmente a sua prática, o interesse das federações nacionais e clubes fez aumentar a demanda pelo assessoramento técnico-científico. O presente artigo investiga, por meio de uma análise documental combinada, o desenvolvimento da indústria, o registro de propriedade intelectual como dispositivo moderador e a centralidade da Federação Internacional de Ginástica (FIG) por meio da exigência de certificação. Os resultados indicam uma recente mudança geopolítica dos fabricantes, com ascensão das corporações chinesas, o aumento dos pedidos de patente e um conjunto restrito de fabricantes que obtiveram a certificação de seus aparelhos. Observamos, ainda, uma indústria nacional defasada em termos tecnológicos e centralizada na região sudeste, condições que mantém a dependência tecnológica do Brasil apesar da melhora substancial dos resultados competitivos dos(as) ginastas brasileiros(as) nos principais eventos desta modalidade.

Authors: Oliveira Mateus Henrique de , Toledo Eliana de
Published: February 2024

A arbitragem possui um papel muito importante no contexto esportivo e seu processo de formação deveria ser cada vez mais cuidado por diferentes instituições, podendo propiciar resultados mais precisos e justos, atletas (da iniciação ao alto rendimento) mais conscientes e motivados(as), árbitros(as) mais realizados com seu trabalho e uma maior valorização do esporte como um fenômeno sócio cultural e formador de valores. Assim, o objetivo desta pesquisa foi analisar os níveis de compreensão e de aplicação de competências práticas dos(as) árbitros(as) de ginástica artística feminina (GAF) e masculina (GAM). Trata-se de um estudo abordagem descritiva, do tipo quantitativa – cujo qual utilizou de estatística descritiva para representar numericamente as respostas dos participantes, além da análise e discussão dos dados de acordo com o aporte teórico e com a visão dos autores sobre o assunto. Como ferramenta de pesquisa foi utilizado o questionário, aplicado para uma amostra de 58 árbitros(as) de GAF (28) e GAM (30). A partir da análise dos dados, por meio de estatística descritiva, identificou-se que os(as) árbitros(as) de ambas as modalidades compreendem e aplicam tais competências de formas semelhantes, com destaque para a autoconfiança e a capacidade de avaliar séries de diferentes níveis. A compreensão e aplicação das competências relacionadas ao componente artístico da modalidade feminina ainda é um item de dificuldade para os(as) árbitros(as) da GAF, enquanto competências relacionadas a comunicação eficiente e de percepção emocional são as de principais diferenças para os árbitros de GAM. Este estudo se mostra relevante para identificar as fragilidades e potencialidades do grupo de árbitros(as) brasileiros(as) em questão e, assim, melhor colaborar com o seu processo de formação para a atuação com a arbitragem em campeonatos nacionais e internacionais.

Published: February 2024

O presente artigo tem como objetivo elencar os saberes considerados importantes por experts de Ginástica Rítmica (GR) para a atuação de treinadoras da modalidade, bem como evidenciar sua articulação com os contextos e situações de aprendizagem. Caracteriza-se como um estudo descritivo de caráter qualitativo e contou com a participação de seis experts da área atuantes em diferentes espaços da GR (treinadoras de seleções nacionais, árbitros internacionais e pesquisadores da área). Utilizou-se como instrumento de pesquisa uma entrevista semiestruturada, elaborada com base em três eixos investigativos, sendo eles: os saberes, os contextos e as situações de aprendizagem. Verificou-se que os saberes adquiridos na experiência que se refletem no fazer prático cotidiano da profissão são prioritários para a formação e intervenção de treinadoras de GR. Eles são assimilados nos contextos não formais e informais de aprendizagem e têm utilização imediata, mas precisam ser empregados de forma criativa e inovadora, além de demandar a necessidade de aprofundar os conhecimentos disciplinares. As situações não mediadas e internas assumem maior expressividade, porém, devem estar articuladas a posturas críticas e reflexivas sobre a atuação. Foi apontada, pelas experts, a necessidade de um curso formativo com certificação que assuma uma identidade da realidade brasileira para o treinamento em ginásticas esportivas.

Published: February 2024

A competição esportiva é inerente ao esporte e, portanto, deve fazer parte do processo de desenvolvimento esportivo, quer seja com foco para a formação do atleta em longo prazo, quer seja para a vida ativa. Logo, a inserção ao ambiente competitivo deve elencar a centralidade no praticante, instigando a progressão de aprendizagem individual e do grupo, a motivação e experiências diversas (e adversas) do esporte. Neste sentido, este artigo discute a formação competitiva na ginástica rítmica, com recorte sobre os eventos na infância. A triangulação de dados entre pesquisa documental, entrevista semiestruturada com 11 treinadoras e 03 gestoras e observação não-participante balizou a Análise de Conteúdo que revelou os ajustes nos eventos de base na GR: imaginário infantil como estratégia para escolha de músicas e/ou figurinos; decoração do ambiente aconchegante; uso do espaço de apresentação ampliando a demonstração síncrona de ginastas; grau de dificuldade de exercícios diferenciados para grupo de idade; arbitragem com postura despretensiosa e flexibilidade na ordem de apresentação a depender do comportamento de cada criança. Os bastidores sugeriam um brincar livre entre ginastas e equipes, proporcionando ambiente acolhedor, propício para experiência positiva incentivadora da permanência na prática.

A revista argumento (Brasil, 1973-1974) e o vazio cheio intelectual nacional
Authors: Barbosa Cairo de Souza
Published: February 2024

O ano de 1964 representou um marco, um corte definitivo na história brasileira. A ditadura civil-militar, dando prosseguimento ao projeto de aprofundamento da ordem capitalista no país, manteve a forma de intervenção política presente em outros momentos: o estado de exceção, isto é, a supressão de direitos fundamentais, além de uma aliança entre burguesia, capital multinacional e associado e dispositivos militares, levando à frente um projeto de modernização conservadora. Entretanto, no campo das artes se da produção intelectual em geral, um ”vazio cheio“ se fez presente, em alguns casos em franca reação à censura. Aqui é ressaltado o papel da Revista Argumento, um periódico publicado entre 1973 e 1974, que serviu como campo de elaboração intelectual e registro das dores sociais, uma resposta à “perplexidade” gerada pela violência e asfixia da ditadura.

BACKGROUND:

A growing number of patients with tetralogy of Fallot develop left ventricular systolic dysfunction and heart failure, in addition to right ventricular dysfunction. Although cardiac resynchronization therapy (CRT) is an established treatment option, the effect of CRT in this population is still not well defined. This study aimed to investigate the early and late efficacy, survival, and safety of CRT in patients with tetralogy of Fallot.

METHODS:

Data were analyzed from an observational, retrospective, multicenter cohort, initiated jointly by the Pediatric and Congenital Electrophysiology Society and the International Society of Adult Congenital Heart Disease. Twelve centers contributed baseline and longitudinal data, including vital status, left ventricular ejection fraction (LVEF), QRS duration, and NYHA functional class. Outcomes were analyzed at early (3 months), intermediate (1 year), and late follow-up (≥2 years) after CRT implantation.

RESULTS:

A total of 44 patients (40.3±19.2 years) with tetralogy of Fallot and CRT were enrolled. Twenty-nine (65.9%) patients had right ventricular pacing before CRT upgrade. The left ventricular ejection fraction improved from 32% [24%–44%] at baseline to 42% [32%–50%] at early follow-up (
P
<0.001) and remained improved from baseline thereafter (
P
≤0.002). The QRS duration decreased from 180 [160–205] ms at baseline to 152 [133–182] ms at early follow-up (
P
<0.001) and remained decreased at intermediate and late follow-up (
P
≤0.001). Patients with upgraded CRT had consistent improvement in left ventricular ejection fraction and QRS duration at each time point (
P
≤0.004). Patients had a significantly improved New York Heart Association functional class after CRT implantation at each time point compared with baseline (
P
≤0.002). The transplant-free survival rates at 3, 5, and 8 years after CRT implantation were 85%, 79%, and 73%.

CONCLUSIONS:

In patients with tetralogy of Fallot treated with CRT consistent improvement in QRS duration, left ventricular ejection fraction, New York Heart Association functional class, and reasonable long-term survival were observed. The findings from this multicenter study support the consideration of CRT in this unique population.

The international symposium Imprints of Ancient Greek and Roman Dance: Texts, Bodies, Images, Movement took place in Madrid in September 2022. As the final component of a research project funded by the Spanish Society of Classical Studies and the BBVA Foundation, this event aimed to scrutinize a series of concepts that have proven significant to the transhistorical and transcultural study of dance. The eight scholars tasked with examining these concepts presented interesting case studies of ancient Greek and Roman dancing between the Archaic period and late Antiquity, drawing upon a variety of media and sources.
Proposed New Article on the Date and Authorship of Names Originally Published with Incomplete Protologues
Authors: De Queiroz Kevin , Cantino Philip , Cellinese Nico
Published: February 2024

When authors have proposed phylogenetically defined names that satisfy the requirements for publication but not those for establishment, the protologues must either be corrected with published errata or republished in a way that satisfies the requirements.  The current version of the PhyloCode does not indicate whether the authorship and date of the names are those of the original publication in which the names were proposed or those of the subsequently published errata or full protologues in which all the requirements for establishment were satisfied.  We propose modifications to the PhyloCode such that for converted clade names (Art. 6.3), the nominal author(s) (Art. 19.1) and date are those of the original publication in which the name was proposed (not the one in which it was first defined phylogenetically), but the definitional author(s) (Art. 19.1) and date are those of the subsequent publication in which all the requirements for establishment are satisfied.  For new clade names (Art. 9.1), we propose that both the nominal author(s) and date and the definitional author(s) and date are those of the subsequent publication in which all the requirements for establishment are satisfied.  An exception is proposed for new clade names that are simultaneously established under a rank-based code.
Precarious Multiculturalism: The Racialized Experience of Asian In/Exclusion in Australia
Authors: Liu Helena , Yu Kyoung-Hee , Wright Chris F.
Published: February 2024

Within Australia’s reputation as a successful multicultural nation, we explore what it means to be Asian in Australia. We trace how this racialized group has been socially excluded under the White Australia Policy that existed for much of the 20th Century, included in the Asian Century adopted as government policy in 2012, re-excluded during the COVID-19 pandemic, and tentatively re-included in its aftermath. We examine the cursory and contingent nature of racial inclusion in Australia in light of the contention that surrounds the concept and practice of multiculturalism as a political program. The racialized experience of Asians in Australia demonstrates the pernicious nature of white supremacy, even while this settler-nation seeks to consolidate a glowing image of diversity to redeem its racist past. We conclude by proposing that Australia go beyond multiculturalism to adopt systemic inclusion as a basis for a more equitable and sustainable future.

The present study evaluated the prognostic significance of right ventricular-pulmonary arterial (RV-PA) coupling, assessed by the tricuspid annular plane systolic excursion to systolic pulmonary artery pressure (TAPSE/sPAP) ratio, in patients undergoing transcatheter aortic valve implantation (TAVI) for severe aortic stenosis (AS). This retrospective, single-center study involved 403 patients (mean age: 78.2 ± 8.4; 50.9% female). RV-PA coupling was categorized based on the pre-procedural TAPSE/sPAP ratio: severe uncoupling (≤0.32), moderate uncoupling (0.32–0.55), and normal coupling (>0.55). The study primary endpoints were in-hospital mortality and 2-year all-cause mortality. Multivariate logistic regression revealed that the TAPSE/sPAP ratio is an independent predictor of both in-hospital (adjusted OR: 0.61, 95% CI [0.44–0.84], P = .002) and 2-year mortality (adjusted OR: 0.69, 95% CI [0.56–0.85], P = .001). Severe uncoupling was strongly associated with increased 2-year mortality (adjusted OR: 3.92, 95% CI [1.67–9.20], P = .002). Our study establishes a significant association between reduced preoperative TAPSE/sPAP ratios and increased risks of both in-hospital and 2-year all-cause mortality in patients undergoing TAVI for severe AS. These results highlight the prognostic utility of evaluating RV-PA coupling. Incorporating this metric into preoperative risk stratification could potentially refine prognostic accuracy and inform clinical decision-making.

We propose tabular two-dimensional correlation spectroscopy analysis for extracting features from multifaceted characterization data, essential for understanding material properties. This method visualizes similarities and phase lags in structural parameter changes through heatmaps, combining hierarchical clustering and asynchronous correlations. We applied the proposed method to data sets of carbon nanotube (CNT) films annealed at various temperatures and revealed the complexity of their hierarchical structures, which include elements such as voids, bundles, and amorphous carbon. Our analysis addresses the challenge of attempting to understand the sequence of structural changes, especially in multifaceted characterization data where 11 structural parameters derived from eight characterization methods interact with complex behavior. The results show how phase lags (asynchronous changes from stimuli), and parameter similarities can illuminate the sequence of structural changes in materials, providing insights into phenomena such as the removal of amorphous carbon and graphitization in annealed CNTs. This approach is beneficial even with limited data and holds promise for a wide range of material analyses, demonstrating its potential in elucidating complex material behaviors and properties.
Underwater terrain-matching algorithm based on improved iterative closest contour point algorithm

Published: February 2024

Although an autonomous underwater vehicle (AUV) is noted for its good autonomy, concealment and anti-interference ability, errors in its inertial navigation system (INS) inevitably increase over time, leading to positional failure during long-term voyages. Terrain-assisted navigation can help the INS to correct its position. The traditional iterative closest contour point (ICCP) achieves high matching accuracy when the initial position error of the INS is small, but is prone to mismatching when the initial error is large. This study combines ICCP with particle swarm optimization (PSO) to overcome this problem. First, the global optimization ability of PSO is improved by changing the acceleration factor and introducing an artificial bee colony (ABC) onlooker bee greedy search (ABC- ωAPSO). Second, the Euclidean distance of ICCP is replaced by the Mahalanobis distance to abate the influence of system error on the matching accuracy. Finally, the initial position error is reduced by rough matching using the ABC- ωAPSO, which has global optimization capability. Next, fine matching is performed by ICCP. This two-step process resolves the sensitivity problem of ICCP to the initial position error. The experimental results revealed a good matching effect after the double-matching procedure. When the initial INS errors were 0.55′ to the east and 0.55′ to the north, the matching error was reduced to 89.3 m, suggesting that the approach can realize autonomous passive navigation of AUVs.

Authors: Barbeito Sara , Gómez-Juncal Rocío , Vega Patricia , Antonio Becerra Juan , Petkari Eleni , González-Pinto Ana , Sánchez-Gutiérrez Teresa
Published: February 2024

Background:

Patients with an ultra-high risk of psychosis (UHR) are more likely to transition to psychosis. Attachment style has also been associated with psychosis and other symptoms.

Aims:

To review attachment styles in UHR patients and to analyze related psychosocial factors. Ours is the first systematic review of attachment in this population.

Method:

We performed a systematic review of attachment and related psychosocial factors in UHR patients following the PRISMA methodology.

Results:

We identified five studies. The results revealed high rates of insecure attachment in this population (more than 80%). The UHR sample presented high levels of depression, anxiety, social anxiety, emotional reactivity, trauma, and poor mentalization. Premorbid social adjustment was a predictor of improvement in disorganization and negative symptoms. The rate of transition to psychosis was 10%. Attachment patterns accounted for 16.8% of the variance. This vulnerability for psychosis was also associated with poor mentalization.

Conclusion:

Early detection of patients with UHR and insecure attachment is crucial, since early intervention to address symptoms, mentalization, and attachment is feasible and may lead to an improvement in the remaining associated psychosocial related factors (secure style: better global functioning and less affective and anxious symptoms).

Published: February 2024

The oral cavity is an epidemiologically relevant route of viral transmission due to the shedding of viruses in saliva. With advancements in salivary diagnostics, an increasing number of viruses have been detected. However, the anatomic source of virus in saliva is still largely unknown. Some viruses have a well-established tropism for the salivary glands (SGs), and recent studies have emphasized the importance of the glands as potential reservoirs for infectious viruses. Viral infections of the SGs have been linked to acute and chronic SG pathology and may be associated with SG dysfunction, with phenotypes similar to those seen in SjÖgren’s disease (SjD), an autoimmune condition that affects the salivary and lacrimal glands. Understanding the breadth of viruses that infect the SG and the conserved or distinct host responses to these infections may provide insights into the pathogenesis of virus-mediated SG diseases. There is a need for further research to fully understand the molecular mechanisms by which viruses enter and replicate in the glands, their physiologic impact on SG function, and whether the SGs can serve as a long-term reservoir for infectious viral particles. The purpose of this review is to highlight a group of viruses that infect the salivary gland: hepatitis C virus, hepatitis D virus, severe acute respiratory syndrome coronavirus 2, enteric viruses, human T-cell leukemia virus type I, human immunodeficiency virus, human cytomegalovirus, and BK polyomavirus. We focus on the effects of viral infection on salivary gland (SG) inflammation, function, and its association with SjD.
