Is public transport a promising strategy for increasing physical activity? Evidence from a study of objectively measured public transport use and physical activity.

BACKGROUND: Greater public transport use has been linked to higher physical activity levels. However, neither the amount of physical activity associated with each daily public transport trip performed, nor the potential total physical activity gain associated with an increase in trips/day, has been determined. Using objective measures, we aimed to quantify the association between public transport use, physical activity and sedentary time. METHODS: A longitudinal study of Australian adults living in Hobart, Tasmania, who were infrequent bus users (≥ 18 years; used bus ≤ 2 times/week). The number of bus trips performed each day was determined from objective smartcard data provided by the public transportation (bus) provider across a 36-week study timeframe. Accelerometer measured steps/day (primary outcome), moderate-to-vigorous physical activity (min/day), and sedentary time (min/day) were assessed across four separate one-week periods. RESULTS: Among 73 participants across 1483 day-level observations, on days that public transport was used, participants achieved significantly more steps (ß = 2147.48; 95%CI = 1465.94, 2829.03), moderate to vigorous physical activity (ß = 22.79; 95% CI = 14.33, 31.26), and sedentary time (ß = 37.00; 95% CI = 19.80, 54.21) compared to days where no public transport trips were made. The largest increase in steps per day associated with a one-trip increase was observed when the number of trips performed each day increased from zero to one (ß = 1761.63; 95%CI = 821.38, 2701.87). The increase in the number of steps per day was smaller and non-significant when the number of trips performed increased from one to two (ß = 596.93; 95%CI=-585.16, 1779.01), and two to three or more (ß = 632.39; 95%CI=-1331.45, 2596.24) trips per day. Significant increases in sedentary time were observed when the number of trips performed increased from zero to one (ß = 39.38; 95%CI = 14.38, 64.39) and one to two (ß = 48.76; 95%CI = 25.39, 72.12); but not when bus trips increased from two to three or more (ß=-27.81; 95%CI=-76.00, 20.37). CONCLUSIONS: Greater public transport use was associated with higher physical activity and sedentary behaviour. Bus use may yield cumulative increases in steps that amount to 15-30% of the daily recommended physical activity target. A policy and public health focus on intersectoral action to promote public transport may yield meaningful increases in physical activity and subsequent health benefits.

Metastatic gastric cancer target lesion complete response with Claudin18.2-CAR T cells.

Treatment of hematologic malignancies with patient-derived anti-CD19 chimeric antigen receptor (CAR) T-cells has demonstrated long-term remissions for patients with otherwise treatment-refractory advanced leukemia and lymphoma. Conversely, CAR T-cell treatment of solid tumors, including advanced gastric cancer (GC), has proven more challenging due to on-target off-tumor toxicities, poor tumor T-cell infiltration, inefficient CAR T-cell expansion, immunosuppressive tumor microenvironments, and demanding preconditioning regimens. We report the exceptional results of autologous Claudin18.2-targeted CAR T cells (CT041) in a patient with metastatic GC, who had progressed on four lines of combined systemic chemotherapy and immunotherapy. After two CT041 infusions, the patient had target lesion complete response and sustained an 8-month overall partial response with only minimal ascites. Moreover, tumor-informed circulating tumor DNA (ctDNA) reductions coincided with rapid CAR T-cell expansion and radiologic response. No severe toxicities occurred, and the patient's quality of life significantly improved. This experience supports targeting Claudin18.2-positive GC with CAR T-cell therapy and helps to validate ctDNA as a biomarker in CAR T-cell therapy. Clinical Insight: Claudin18.2-targeted CAR T cells can safely provide complete objective and ctDNA response in salvage metastatic GC.

Development of therapeutic monoclonal antibodies against DKK1 peptide-HLA-A2 complex to treat human cancers.

BACKGROUND: Targeted immunotherapy with monoclonal antibodies (mAbs) is an effective and safe method for the treatment of malignancies. Development of mAbs with improved cytotoxicity, targeting new and known tumor-associated antigens, therefore continues to be an active research area. We reported that Dickkopf-1 (DKK1) is a good target for immunotherapy of human cancers based on its wide expression in different cancers but not in normal tissues. As DKK1 is a secreted protein, mAbs binding directly to DKK1 have limited effects on cancer cells in vivo. METHODS: The specificity and antibody-binding capacity of DKK1-A2 mAbs were determined using indirect ELISA, confocal imaging, QIFIKIT antibody-binding capacity and cell surface binding assays. The affinity of mAbs was determined using a surface plasmon resonance biosensor. A flow cytometry-based cell death was performed to detect tumor cell apoptosis. Antibody-dependent cellular cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC) assays were used to evaluate the ability of DKK1-A2 mAbs to mediate ADCC and CDC activities against tumor cells in vitro. Flow cytometry data were collected with an FACSymphony A3 cell analyzer and analyzed with FlowJo V.10.1 software. Human cancer xenograft mouse models were used to determine the in vivo therapeutic efficacy and the potential safety and toxicity of DKK1-A2 mAbs. In situ TUNEL assay was performed to detect apoptosis in tumors and mouse organs. RESULTS: We generated novel DKK1-A2 mAbs that recognize the DKK1 P20 peptide presented by human HLA-A*0201 (HLA-A2) molecules (DKK1-A2 complexes) that are naturally expressed by HLA-A2+DKK1+ cancer cells. These mAbs directly induced apoptosis in HLA-A2+DKK1+ hematologic and solid cancer cells by activating the caspase-9 cascade, effectively lysed the cancer cells in vitro by mediating CDC and ADCC and were therapeutic against established cancers in their xenograft mouse models. As DKK1 is not detected in most human tissues, DKK1-A2 mAbs neither bound to or killed HLA-A2+ blood cells in vitro nor caused tissue damage in tumor-free or tumor-bearing HLA-A2-transgenic mice. CONCLUSION: Our study suggests that DKK1-A2 mAbs may be a promising therapeutic agent to treat human cancers.

Characterization of a Diverse Set of Conditionally Reprogrammed Head and Neck Cancer Cell Cultures.

OBJECTIVE: To establish and characterize a diverse library of head and neck squamous cell cancer (HNSCC) cultures using conditional reprogramming (CR). METHODS: Patients enrolled on an IRB-approved protocol to generate tumor cell cultures using CR methods. Tumor and blood samples were collected and clinical information was recorded. Successful CR cultures were validated against banked reference tumors with short tandem repeat genotyping. Cell morphology was archived with photodocumentation. Clinical and demographic factors were evaluated for associations with successful establishment of CR culture. Human papilloma virus (HPV) genotyping, clonogenic survival, MTT assays, spheroid growth, and whole exome sequencing were carried out in selected cultures. RESULTS: Forty four patients were enrolled, with 31 (70%) successful CR cultures, 32% derived from patients who identified as Black and 61% as Hispanic. All major head and neck disease sites were represented, including 15 (48%) oral cavity and 8 (26%) p16-positive oropharynx cancers. Hispanic ethnicity and first primary tumors (vs. second primary or recurrent tumors) were significantly associated with successful CR culture. HPV expression was conserved in CR cultures, including CR-024, which carried a novel HPV-69 serotype. CR cultures were used to test cisplatin responses using MTT assays. Previous work has also demonstrated these models can be used to assess response to radiation and can be engrafted in mouse models. Whole exome sequencing demonstrated that CR cultures preserved tumor mutation burden and driver mutations. CONCLUSION: CR culture is highly successful in propagating HNSCC cells. This study included a high proportion of patients from underrepresented minority groups. LEVEL OF EVIDENCE: Not Applicable Laryngoscope, 134:2748-2756, 2024.

Cardiology researchers' practices and perceived barriers to open science: an international survey.

OBJECTIVE: Open science is a movement and set of practices to conduct research more transparently. Implementing open science will significantly improve public access and supports equity. It also has the potential to foster innovation and reduce duplication through data and materials sharing. Here, we survey an international group of researchers publishing in cardiovascular journals regarding their perceptions and practices related to open science. METHODS: We identified the top 100 'Cardiology and Cardiovascular Medicine' subject category journals from the SCImago journal ranking platform. This is a publicly available portal that draws from Scopus. We then extracted the corresponding author's name and email from all articles published in these journals between 1 March 2021 and 1 March 2022. Participants were sent a purpose-built survey about open science. The survey contained primarily multiple choice and scale-based questions for which we report count data and percentages. For the few text-based responses we conducted thematic content analysis. RESULTS: 198 participants responded to our survey. Participants had a mean response of 6.8 (N=197, SD=1.8) on a 9-point scale with endpoints, not at all familiar (1) and extremely familiar (9), when indicating how familiar they were with open science. When asked about where they obtained open science training, most participants indicated this was done on the job self-initiated while conducting research (n=103, 52%), or that they had no formal training with respect to open science (n=72, 36%). More than half of the participants indicated they would benefit from practical support from their institution on how to perform open science practices (N=106, 54%). A diversity of barriers to each of the open science practices presented to participants were acknowledged. Participants indicated that funding was the most essential incentive to adopt open science. CONCLUSIONS: It is clear that policy alone will not lead to the effective implementation of open science. This survey serves as a baseline for the cardiovascular research community's open science performance and perception and can be used to inform future interventions and monitoring.

Intravesical Ty21a treatment of non-muscle invasive bladder cancer induces immune responses that correlate with safety and may be associated to therapy potential.

BACKGROUND: Standard of care treatment of non-muscle invasive bladder cancer (NMIBC) with intravesical Bacillus Calmette Guérin (BCG) is associated with side effects, disease recurrence/progression and supply shortages. We recently showed in a phase I trial (NCT03421236) that intravesical instillation in patients with NMIBC with the maximal tolerated dose of Ty21a/Vivotif, the oral vaccine against typhoid fever, might have a better safety profile. In the present report, we assessed the immunogenicity of intravesical Ty21a in patients of the clinical trial that had received the maximal tolerated dose and compared it with data obtained in patients that had received standard BCG. METHODS: Urinary cytokines and immune cells of patients with NMIBC treated with intravesical instillations of Ty21a (n=13, groups A and F in NCT03421236) or with standard BCG in a concomitant observational study (n=12, UROV1) were determined by Luminex and flow cytometry, respectively. Serum anti-lipopolysaccharide Typhi antibodies and circulating Ty21a-specific T-cell responses were also determined in the Ty21a patients. Multiple comparisons of different paired variables were performed with a mixed-effect analysis, followed by Sidak post-test. Single comparisons were performed with a paired or an unpaired Student's t-test. RESULTS: As compared with BCG, Ty21a induced lower levels of inflammatory urinary cytokines, which correlated to the milder adverse events (AEs) observed in Ty21a patients. However, both Ty21a and BCG induced a Th1 tumor environment. Peripheral Ty21a-specific T-cell responses and/or antibodies were observed in most Ty21a patients, pointing the bladder as an efficient local immune inductive site. Besides, Ty21a-mediated stimulation of unconventional Vδ2 T cells was also observed, which turned out more efficient than BCG. Finally, few Ty21a instillations were sufficient for increasing urinary infiltration of dendritic cells and T cells, which were previously associated with therapeutic efficacy in the orthotopic mouse model of NMIBC. CONCLUSIONS: Ty21a immunotherapy of patient with NMIBC is promising with fewer inflammatory cytokines and mild AE, but induction of immune responses with possible antitumor potentials. Future phase II clinical trials are necessary to explore possible efficacy of intravesical Ty21a.

Stage 4 - review by an evaluation committee. Stage 5 - application to a population of 20 people. Results: There were no comprehension problems for the final population from the evaluation committee. Conclusion: The questionnaire was successfully translated and adapted.

Impact of economic factors and knowledge translation on public procurement for dental adhesive systems

Abstract: This study aimed to screen the public procurement for dental adhesives in a public health system and evaluate the variables associated with the type and cost of purchased materials. A time series was conducted with secondary data collated from the Brazilian Databank of Healthcare Prices (BDHP). All public procurements for adhesive systems registered from 2010 to 2019 were collated. The frequency of purchase was described, and a multiple linear regression model was used to assess the influence of unit price on predictor variables. Multinomial logistic regression was conducted to describe the influence of selected variables on the probability of purchase for different classes of adhesive systems. A total of 2,752 purchases were analyzed, and the total cost of these materials reached US$ 7,022,659.00 in the 10 analyzed years. The 3-step Etch & Rinse adhesives corresponded to 45.63% of the processes, with increased probability of being purchased over time. The process conducted by public universities in recent years, using the auction modality, presented lower unit prices. The year of purchase, the type of institutions, the institution's location, and the procurement modality influenced the procurement process. The performed analyses contribute to the understanding of the variables associated with the procurements for adhesive systems, providing valuable information for rationalizing public expenditure and for implementing evidence-based practices to guarantee cost-effective and clinically effective procedures for users of the Brazilian public healthcare system.

Testes diagnósticos nacionais: insumos essenciais para a vigilância sindrômica da Covid-19 / Brazilian diagnostic tests: essential health supplies for COVID-19 syndromic surveillance

RESUMO Existe ampla evidência que a contenção da pandemia de Covid-19 requer vigilância sindrômica e isolamento de casos suspeitos/confirmados. É essencial a disponibilidade de testes diagnósticos no Sistema Único de Saúde, que poderia ser facilitada pela soberania nacional no desenvolvimento e produção, considerando-se a alta demanda/escassez no mercado internacional. Este estudo identificou as etapas da pesquisa translacional de testes diagnósticos para Covid-19 no Brasil, verificando sua distribuição geográfica, entre outros indicadores. Estudo transversal, exploratório, partindo de banco público com 789 projetos de Pesquisa, Desenvolvimento e Inovação (PD&I) em Covid-19, complementado com outras buscas, inclusive no CVLattes dos pesquisadores. No banco, havia 89 projetos de testes diagnósticos. Em 45 casos, foi possível obter informações complementares para classificá-los conforme as etapas da pesquisa translacional. Identificaram-se 15 inovações que atingiram o estágio T3, ou seja, tiveram seus produtos incorporados em protocolos clínicos na atenção à saúde, mesmo considerando-se as profundas restrições orçamentárias em PD&I. O Brasil possui potencial de desenvolvimento e implementação de produtos tecnológicos na área de testes de diagnóstico para Sars-CoV-2. Políticas públicas de PD&I em saúde necessitam ser priorizadas para ampliação de cooperações nacionais e internacionais, a fim de promover efetiva autonomia nacional na vigilância sindrômica e à saúde da população.

ABSTRACT There is much evidence suggesting that mitigating the COVID-19 pandemic requires syndromic surveillance and isolation of suspected/confirmed cases. The availability of diagnostic tests in the Brazilian Unified Health System (SUS) is essential, which could be facilitated by national sovereignty in development and production, considering the high demand/lack of supply in the international market. This study identified the stages of translational research into diagnostic tests for COVID-19 in Brazil, verifying their geographic distribution, among other indicators. A cross-sectional, exploratory study based on a public database with 789 Research, Development, and Innovation (RD&I) projects regarding COVID-19, complemented by other searches, including the researchers' curricula (CVLattes). There were 89 diagnostic test projects in the database. In 45 cases, it was possible to obtain additional information to classify them according to the translational research stages. Fifteen innovations that reached the T3 stage were identified, with their products incorporated into clinical protocols in healthcare, even considering the deep budget restrictions in RD&I. Brazil has the potential to develop and implement technological products in the field of diagnostic tests for SARS-CoV-2. Public health RD&I policies need to be prioritized to expand national and international cooperation to promote effective national autonomy in syndromic surveillance and population health.

Impacto de uma intervenção educativa no manejo da hipotermia terapêutica neonatal: estudo quase experimental / Impact of an educational intervention in the management of neonatal therapeutic hypothermia: a quasi-experimental study

Introdução: A hipotermia terapêutica é o tratamento indicado para encefalopatia moderada a grave em recém-nascidos. A terapia requer uma equipe de enfermagem capacitada e integrada, visando um cuidado qualificado, efetivo e seguro. Modelos teóricos têm sido desenvolvidos para auxiliar a incorporação de evidências científicas à prática dos enfermeiros, representando um desafio na área da saúde. A implementação de uma intervenção educativa, guiada pela estrutura i-PARIHS (Estrutura Integrada de Promoção da Ação na Implementação de Pesquisa em Serviços de Saúde), poderá preencher a lacuna entre a teoria e a prática, beneficiando a assistência e tornando os sujeitos ativos no manejo do recém-nascido em hipotermia terapêutica. Objetivo geral: avaliar o impacto de uma intervenção educativa, guiada pelo referencial teórico i-PARIHS, sobre o manejo do recém-nascido com asfixia perinatal em hipotermia terapêutica na unidade intensiva neonatal no conhecimento, atitudes e práticas de enfermeiros. Objetivos específicos: analisar o conhecimento, atitude e prática dos enfermeiros sobre o manejo do recém-nascido com asfixia perinatal em hipotermia terapêutica pré e pós-intervenção educativa; identificar as barreiras e facilitadores percebidos pelos enfermeiros sobre o manejo do recém-nascido com asfixia perinatal em hipotermia terapêutica na unidade intensiva neonatal; implementar uma intervenção educativa, guiada pelo referencial i-PARIHS, para melhorar o conhecimento, a atitude e a prática dos enfermeiros sobre o manejo do recém-nascido com asfixia perinatal em hipotermia terapêutica na unidade intensiva neonatal; comparar o conhecimento, atitude e prática dos enfermeiros após a intervenção educativa e os indicadores quanto ao manejo do recém-nascido com asfixia perinatal em hipotermia terapêutica. Método: trata-se de um estudo de intervenção, do tipo quase-experimental, realizado com 29 enfermeiros de uma unidade intensiva neonatal, referência no Rio de Janeiro. O desfecho principal: conhecimento, atitudes e práticas dos enfermeiros no manejo do recém-nascido com asfixia perinatal em hipotermia terapêutica na unidade intensiva neonatal A intervenção compreendeu três fases: pré-intervenção - intervenção educativa- pós-intervenção. A intervenção educativa contou com cinco encontros: "Asfixia Perinatal x Hipotermia Terapêutica", "Controle da temperatura", "Cuidados de enfermagem na HT: avaliação de dor", "Monitoramento neurológico" e "Cuidado Centrado na Família". Para a análise estatística utilizou-se de análise descritiva e aplicação dos testes Wilcoxon-Mann-Whitney e Mc Nemar, sendo o nível de significância adotado de 0,05. Resultados: a análise dos resultados do pré e pós-teste demonstrou um incremento no escore de acertos das questões sobre conhecimento, atitude e prática dos enfermeiros no manejo do recém-nascido submetido à hipotermia terapêutica na unidade intensiva neonatal, apresentando significância estatística para a maioria dos itens. Para a inovação foram construídos lembretes, fluxo de admissão para recém-nascido da instituição e uma cartilha para os pais como produto da intervenção com os enfermeiros. Conclusão: O resultado das auditorias realizadas, após a implementação das evidências, constatou uma transformação positiva da prática dos enfermeiros. A utilização da estrutura i-PARIHS evidenciou a necessidade e o valor de investir no engajamento das partes interessadas, na avaliação colaborativa do contexto e na cocriação de inovação usando facilitação qualificada. A intervenção educativa, guiada pela estrutura i-PARIHS, mostrou ter impacto no manejo do recém-nascido submetido à hipotermia terapêutica por enfermeiros.

Introduction: Therapeutic hypothermia is the currently indicated treatment for moderate to severe encephalopathy in newborns. Therapy requires a trained and integrated nursing team, aiming at qualified, effective and safe care. Theoretical models have been developed to help the incorporation of scientific evidence into nurses' practice, representing a challenge in the health area. The implementation of an educational intervention, guided by the i-PARIHS (Integrated Promoting Action on Research Implementation in Health Services Framework) framework, can fill the gap between theory and professional practice, benefiting care and making subjects active in the management of newborns with therapeutic hypothermia. General objective: to evaluate the impact of an educational intervention guided by the theoretical framework i-PARIHS, on the management of newborns with perinatal asphyxia in therapeutic hypothermia in the neonatal intensive care unit on the knowledge, attitudes and practices of nurses. Specific objectives: to analyze the knowledge, attitude and practice of nurses on the management of newborns with perinatal asphyxia in pre- and post-educational therapeutic hypothermia; to identify barriers and facilitators perceived by nurses on the management of newborns with perinatal asphyxia in therapeutic hypothermia in the neonatal intensive care unit; implement an educational intervention, guided by the i-PARIHS framework, to improve nurses' knowledge, attitude and practice on the management of newborns with perinatal asphyxia in therapeutic hypothermia in the neonatal intensive care unit and compare the knowledge, attitude and practice of nurses after the participatory educational intervention program and indicators regarding the management of newborns with perinatal asphyxia in therapeutic hypothermia. Method: this is a quasi-experimental intervention study carried out with 29 nurses from a neonatal intensive care unit, a reference in Rio de Janeiro. The main outcome: knowledge, attitudes and practices of nurses in the management of newborns with perinatal asphyxia in therapeutic hypothermia in the neonatal intensive unit The intervention comprised three phases: pre-intervention - educational intervention - post-intervention. The educational intervention had five meetings: "Perinatal Asphyxia x Therapeutic Hypothermia", "Temperature control", "Nursing care in HT: pain assessment", "Neurological monitoring" and "Family-Centered Care". For the statistical analysis, descriptive analysis and application of the Wilcoxon-Mann-Whitney and Mc Nemar tests were used, with the adopted significance level of 0.05. Results: the analysis of pre- and post-test results showed an increase in the correct score of questions about nurses' knowledge and practices in the management of newborns submitted to therapeutic hypothermia in the neonatal intensive care unit, showing statistical significance for most items. For innovation, reminders, admission flow for newborns at the institution and a booklet for parents were created as a product of the intervention with nurses. Conclusion: The result of the audits carried out, after the implementation of the evidence, found a positive transformation of the nurses' practice. Using the i-PARIHS framework highlighted the need and value of investing in stakeholder engagement, collaborative context assessment, and co-creation of innovation using qualified facilitation. The educational intervention guided by the i-PARIHS framework was shown to have an impact on the management of newborns with perinatal asphyxia in therapeutic hypothermia by nurses.

Adaptação cultural do questionário de avaliação de resultados em rejuvenescimento de pele (Skin Rejuvenation Outcome Evaluation - SROE) / Cultural adaptation of the questionnaire on skin rejuvenation outcome evaluation (Skin Rejuvenation Outcome Evaluation - SROE)

Introdução: O emprego de questionários de qualidade de vida (QV) tem se mostrado muito útil no sentido de dar maior objetividade à avaliação de resultados de tratamentos. A internacionalização desses instrumentos, por sua vez, permite a comparação interpopulacional, mas requer uma metodologia específica, a fim de não causar distorções devido a falhas na tradução ou a diferenças culturais. O questionário SROE (Skin Rejuvenation Outcome Evaluation), de língua inglesa, é uma ferramenta de simples aplicação, com perguntas objetivas com boa aplicação para esse fim. O questionário já foi testado em relação à sua confiabilidade, validade e capacidade de resposta. Métodos: Realizada tradução e adaptação cultural para a língua portuguesa, segundo a metodologia proposta por Beaton et al. (2000), na qual existem 5 estágios: estágio 1 - tradução por meio de dois tradutores nativos de língua portuguesa; estágio 2 - confecção de versão de síntese; estágio 3 - tradução reversa por dois tradutores nativos de língua inglesa; estágio 4 - revisão por um comitê avaliador; e, estágio 5 - aplicação a uma população de 20 pessoas. Resultados: O questionário foi traduzido e adaptado com sucesso, sem problemas de compreensão para a população final. Conclusão: Considerando a metodologia aplicada, concluímos que a tradução do questionário SROE é adequada para utilização em língua portuguesa do Brasil.

Introduction: The use of quality of life (QOL) questionnaires has been shown to be very useful in the sense of giving greater objectivity to the treatment outcomes evaluation. The internationalization of these instruments, in turn, allows for inter-population comparison but requires a specific methodology in order not to cause distortions due to flaws in translation or cultural differences. The SROE questionnaire (Skin Rejuvenation Outcome Evaluation), in English, is a simple application tool, with objective questions with a good application for this purpose. The questionnaire has already been tested for its reliability, validity, and responsiveness. Methods: Translation and cultural adaptation to the Portuguese language was carried out, according to the methodology proposed by Beaton et al. (2000), in which there are five stages: stage 1 - translation using two native Portuguese-speaking translators; stage 2 - making a synthesis version; stage 3 - reverse translation by two native Englishspeaking translators; stage 4 - review by an evaluation committee; and, stage 5 - application to a population of 20 people. Results: The questionnaire was successfully translated and adapted, without problems of understanding for the final population. Conclusion: Considering the applied methodology, we conclude that the SROE questionnaire's translation is suitable for use in Brazilian Portuguese.
