Targeting stroma and tumor, silencing galectin 1 treats orthotopic mouse hepatocellular carcinoma

This study examines inhibiting galectin 1 (Gal1) as a treatment option for hepatocellular carcinoma (HCC). Gal1 has immunosuppressive and cancer-promoting roles. Our data showed that Gal1 was highly expressed in human and mouse HCC. The levels of Gal1 positively correlated with the stages of human HCC and negatively with survival. The roles of Gal1 in HCC were studied using overexpression (OE) or silencing using Igals1 siRNA delivered by AAV9. Prior to HCC initiation induced by RAS and AKT mutations, lgals1-OE and silencing had opposite impacts on tumor load. The treatment effect of lgals1 siRNA was further demonstrated by intersecting HCC at different time points when the tumor load had already reached 9% or even 42% of the body weight. Comparing spatial transcriptomic profiles of Gal1 silenced and OE HCC, inhibiting matrix formation and recognition of foreign antigen in CD45+ cell-enriched areas located at tumor-margin likely contributed to the anti-HCC effects of Gal1 silencing. Within the tumors, silencing Gal1 inhibited translational initiation, elongation, and termination. Furthermore, Gal1 silencing increased immune cells as well as expanded cytotoxic T cells within the tumor, and the anti-HCC effect of lgals1 siRNA was CD8-dependent. Overall, Gal1 silencing has a promising potential for HCC treatment.

CircSLC8A1_005 Inhibits the Fibrotic Phenotype of Cardiac Fibroblasts by Encoding Protein / 中山大学学报(医学科学版)

ObjectiveTo investigate the effect of circSLC8A1_005 on the fibrotic phenotype of cardiac fibroblasts and the potential mechanism involved. MethodsThe effect of adenovirus-mediated overexpression of circSLC8A1_005 on the expression of fibrosis-related genes， collagen type I alpha 1 chain （Col1a1）， collagen type Ⅲ alpha 1 chain （Col3a1） and smooth muscle actin alpha 2 （Acta2）， in mouse cardiac fibroblasts （mCFs） were detected. The proliferation and migration activities of mCFs were detected by EdU and wound-healing assay， respectively. Dual luciferase reporter gene assay was performed to detect the activity of potential internal ribozyme entry site （IRES） in circSLC8A1_005. CircSLC8A1_005-translated protein， SLC8A1-605aa， and its intracellular distribution was identified by Western blot assay. The effect of SLC8A1-605aa protein on transcription activity of Sod2 gene was detected by the dual luciferase reporter gene assay. RNA binding protein immunoprecipitation （RIP） was utilized to verify the interaction between SLC8A1-605aa and superoxide dismutase 2 （Sod2） mRNA. Actinomycin D treatment was used to detect the effect of SLC8A1-605aa on Sod2 mRNA stability in mCFs. ResultsAn efficient adenovirus-mediated overexpression of circSLC8A1_005 was achieved in mCFs. The enforced expression of circSLC8A1_005 suppressed proliferation and migration of mCFs， and inhibited the expression of fibrosis-related genes in mCFs. The dual luciferase reporter gene assay revealed the activities of 2 IRES in circSLC8A1_005. Results of Western blot assay showed that circSLC8A1_005 could translate protein SLC8A1-605aa with the prospected molecular weight of 70 ku， which is predominantly distributed in the nucleus. Overexpression of the circSLC8A1_005 and SLC8A1-605aa could consistently inhibit the fibrotic phenotype of mCFs. SLC8A1-605aa could up-regulate superoxide dismutase 2 （Sod2） expression， but not at the transcriptional level. RIP assay indicated that SLC8A1-605aa could specifically interact with Sod2 mRNA， and the results of actinomycin D assay showed that SLC8A1-605aa could enhance the stability of Sod2 mRNA in mCFs. ConclusionCircSLC8A1_005 inhibits the fibrotic phenotype of cardiac fibroblasts via translating SLC8A1-605aa protein， and SLC8A1-605aa may be a potential target for the treatment of myocardial fibrosis.

Método o estudo foi desenvolvido em duas etapas: adaptação transcultural e pré-teste. 1. Adaptação transcultural: foi composta por uma equipe de dois fonoaudiólogos e dois não-fonoaudiólogos, sendo responsáveis pela tradução para o português (um fonoaudiólogo e um não-fonoaudiólogo nativos do português brasileiro - PB e falantes do inglês), de modo independente, com posterior consenso realizado pelos pesquisadores; retrotradução para o inglês (um fonoaudiólogo e um não-fonoaudiólogo nativos do inglês e falantes do PB); análise da versão final por um comitê (um tradutor, um metodologista, e três fonoaudiólogos). 2. Etapa de pré-teste: os instrumentos foram aplicados em 38 indivíduos transgêneros (29 mulheres trans, 2 travestis e 7 homens trans), sendo acrescido na chave de resposta a opção "não aplicável". Os dados foram analisados de forma descritiva e inferencial. Resultados No processo de adaptação transcultural do VCS houve ajustes em cinco itens do questionário, quatro deles quanto à forma e um quanto ao conteúdo. Para o TSC também foram necessários ajustes quanto a forma em cinco itens. No pré-teste, para todos os itens dos instrumentos, a opção não aplicável apresentou proporção significativamente menor que as opções da chave de resposta dos instrumentos. Por fim, foi obtida uma versão traduzida e adaptada para o português dos dois instrumentos. Conclusão Os instrumentos foram transculturalmente adaptados para o português brasileiro e nomeados como Escala de Congruência Vocal e Escala de Congruência da Pessoa Transgênero.

ABSTRACT Purpose to carry out the cross-cultural adaptation of the Vocal Congruence Scale (VCS) and the Transgender Scale Congruence (TSC) instruments into Brazilian Portuguese. Methods the study was developed in two stages: cross-cultural adaptation and pre-test. 1. Cross-cultural adaptation: it was composed of a team of two speech therapists and two non-speech therapists, being responsible for the translation of the instruments into Portuguese (a speech therapist and a non-speech therapist native to Brazilian Portuguese - BP and English speakers, independently, with subsequent consensus achieved by the researchers; back-translation of the instruments into English (a speech therapist and a non-speech therapist who are native speakers of English and speakers of BP); analysis of the final version by a committee (a translator, a methodologist, and three speech therapists). Data were analyzed descriptively and inferentially. Results In the cross-cultural adaptation process of the VCS there were adjustments in five items of the questionnaire, four of them in terms of form and one in terms of content. necessary adjustments regarding form in five items. In the pre-test, for all VCS and TSC items, the non-applicable option had a significantly lower proportion than the instrument response key options (p<0.001, for all). Finally, a translated and adapted version for Brazilian Portuguese of the Vocal Congruence Scale (VCS) and the Transgender Scale Congruence (TSC) instruments was obtained. Conclusion The VCS and TSC were transculturally adapted to Brazilian Portuguese and named as Vocal Congruence Scale and Transgender Person Congruence Scale.

The Brazilian version of the High-Activity Arthroplasty Score: cross-cultural adaptation

ABSTRACT BACKGROUND: The High Activity Arthroplasty Score (HAAS) is a self-administered questionnaire, developed in British English, that reliably and validly measures the levels of sports activities in patients following hip and knee arthroplasty surgery. OBJECTIVE: To cross-culturally adapt the HAAS to Brazilian Portuguese language. DESIGN AND SETTING: A cross-sectional study was conducted at a public university hospital in Brazil. METHODS: The Brazilian version of the HAAS was created through a six-step process: translation, synthesis, committee review, pretesting, back-translation, and submission to developers. The translation step was conducted by two independent bilingual translators, both native speakers of Brazilian Portuguese. The back-translation was performed by an independent translator, a native speaker of British English. To ensure the questionnaire's comprehensibility, 46 volunteers (51% men; average age 34-63) participated in the pre-testing step. RESULTS: The cross-cultural adaptation process necessitated modifications to certain terms and expressions to achieve cultural equivalence with the original HAAS. CONCLUSION: The HAAS has been translated from English into Brazilian Portuguese and culturally adapted for Brazil. The validation process for HAAS-Brazil is currently underway.

Marathi translation, linguistic validation, and cross?cultural adaptation of M.D. Anderson dysphagia inventory in patients of head and neck squamous cell cancer

Background: Self?reported treatment outcome is a better way to measure patient抯 quality of life (QOL). This study was undertaken to translate dysphagia?specific QOL questionnaire M. D. Anderson Dysphagia Inventory (MDADI) in Marathi language, its linguistic validation, and cross?cultural adaptation in patients of head and neck squamous cell cancer (HNSCC). Methods: After Institutional ethics committee approval, MDADI was translated into Marathi with prior permission from the author of original English questionnaire (AOEQ). The translation procedure included � two forward translations (English to Marathi), formation of first intermediate Marathi translation (FIMT), two back translations (BT) (Marathi to English) of FIMT and interim Marathi translation (IMT) formation. Second intermediate Marathi translation (SIMT) was prepared after face validation of IMT by Marathi subject expert. Pretesting of SIMT was done in 10 patients of HNSCC for linguistic validation and cross?cultural adaptation. After incorporating the patients� suggestions, final Marathi translation was formulated and forwarded to primary author for approval. Results: The grammatically acceptable and conceptually equivalent face?validated SIMT was prepared and given to HNSCC patients. The questionnaire was well understood and unobjectionable reflecting its linguistic validity and cross?cultural adaptation. Some of the patients suggested changes in a few words which were then rectified, rechecked with BT, and the final Marathi translated questionnaire was prepared. The credit statement for AOEQ was used as a footnote in the translated questionnaire. Conclusion: Marathi translation of MDADI is well accepted and comprehensible. It can be used for future studies.

Translation and cultural adaptation of the Short Version of the Reflux Symptom Score: Reflux Symptom Score-12 into Brazilian Portuguese

Abstract Objective: To describe the process of translation into Brazilian Portuguese and cross-cultural adaptation of the French Reflux Symptom Score-12 questionnaire used for the diagnosis of laryngopharyngeal reflux. Methods: This was across-cultural translation and adaptation study of a health instrument, with a cross-sectional design. It was carried out in eight stages: translation from French into Brazilian Portuguese, cultural adaptation by a panel of experts, application of the first version (pilot test 1), adaptation by a panel of experts, application of the second version (pilot test 2), back translation, reviewing by a committee in conjunction with the author of the original instrument and, application of the final version. The Brazilian Portuguese versions of the questionnaire were applied to individuals with symptoms and signs of laryngopharyngeal reflux who underwent pHmetry and esophageal manometry at the study site. Results: In pilot test 1, the first version of the RSS-12 in Brazilian Portuguese was applied to 30 patients. The patients had no difficulty to understand any of the 12 symptom items, but 15 patients (50%) had difficulty interpreting the symptom frequency score. After adapting the format of the frequency score, a version 2 of the RSS-12 in Brazilian Portuguese was applied to another 23 patients, who completed the questionnaire in full without any difficulty. Along with the review committee, the author of the original RSS-12 considered the version 2 to be adequate and did not propose any changes, so it was approved as the final version of the Brazilian Portuguese RSS-12. Conclusion: The Brazilian Portuguese version of the instrument, called Reflux Symptom Score-12 PT-BR, shows good understanding and linguistic, conceptual and content equivalence, in relation to the original Reflux Symptom Score-12.

The "Five- part questionnaire on hypermobility" is a self- administered tool that allows early identification of joint hypermobility. Objective To carry out the cultural adaptation and test- retest reliability of the "Five- part questionnaire on hypermobility" to the Peruvian context through translation into spanish, linguistic adaptation, and verification of test- retest reliability in students from 13 to 17 years of age and teachers/ad-ministrators from 24 to 60 years of age. Methods A translation and back- translation were performed with two translators and two back- translators, followed by a linguistic adaptation with ten experts. Once the adapted version of the question-naire was obtained, a comprehensibility analysis was carried out with 50 subjects. Finally, test- retest reliability was estimated in two groups: adolescents aged 13 to 17 and adults aged 24 to 60. Results The translated version of the questionnaire was obtained and underwent a linguistic adaptation process in which ten experts performed a concordance analysis (Aiken's V coefficient = 1), and a comprehensibility analysis with a scale of zero to ten obtained an average of ten points. Subsequently, this version was back- translated and checked against the original. In the reliability analysis, the results of the test- retest application found high reliability between the total score of both applications for both the group of 65 adults (Kappa 0.795; 95% CI: 0.777 to 0.819) and the group of 71 adolescents (Kappa 0.946; 95% CI: 0.908 to 0.982). Conclusions The translated instrument "Five- part questionnaire (5pq) on hypermobility" was adapted to the Peruvian cultural context, and high reliability was found for the study groups 13 to 17 years and 24 to 60 years. Concurrent validation is recommended to consider its application in clinical and research settings.

Essa escala favorece a eficácia da assistência prestada pela equipe de saúde na temática da morte. Foi projetada pela enfermeira Katherine Helen Murray Frommelt em 1989, com o objetivo de avaliar as atitudes dos enfermeiros em relação ao cuidado de pessoas em estado terminal e suas famílias. Posteriormente, sua aplicação foi estendida para outros profissionais, como médicos. Este estudo foi aprovado pelo Comitê de Ética em Pesquisa em Seres Humanos do Setor de Ciências da Saúde da Universidade Federal do Paraná com a CAEE 55547522.1.0000.0102. Foi desenvolvido entre julho de 2021 a janeiro de 2023, no formato online e envolveu as etapas: tradução; síntese; retrotradução; revisão por um comitê de especialistas; pré-teste e versão final da escala. Foram recrutados como participantes: tradutores juramentados; tradutor da área da saúde; retrotradutores norte-americanos; especialistas, dentre os quais médicos, enfermeiros, profissional formado em letras português-inglês e profissionais médicos e enfermeiros associados à Sociedade Brasileira de Geriatria e Gerontologia que participaram do pré-teste. Todos foram selecionados mediante critérios de inclusão e exclusão. A versão da FATCOD-B scale finalizada pelos especialistas, foi aplicada no pré-teste a 75 médicos e 12 enfermeiros, que também responderam a um questionário sociodemográfico que continha perguntas referentes a sexo, idade, religião, profissão, educação prévia sobre o morrer e a morte, experiência prévia com a perda, experiência presente com a perda e experiência prévia no cuidado de pessoas com doenças terminais. Para avaliar as associações entre as respostas da FATCOD-B scale foi utilizado o teste qui-quadrado ou o teste exato de Fisher. Todos os testes foram realizados considerando o nível de 5% de significância e utilizou-se a linguagem de programação R.4.1.2. Dos 87 participantes, 57,4% tinham até 45 anos; 66,7% eram mulheres; 55,2% eram católicos; 73,6% apontaram a crença religiosa como geradora de atitudes sobre o morrer e a morte; 96,6% tinham experiência prévia no cuidado de pessoas com doenças terminais, 72,43% experienciaram a perda de familiares próximos ou outra pessoa significante, 65,5% não fizaram curso específico sobre o morrer e a morte, mas tiveram o assunto abordado em outros cursos. Observou-se que as variáveis idade, sexo, religião, experiência prévia com a perda e a educação prévia sobre o morrer e a morte são fatores associados às atitudes diante do morrer e da morte (p<0,05). Os participantes apresentaram atitudes positivas diante do morrer e da morte, pontuando 121 ± 0,68 na escala FATCOD-B. O Alfa de Cronbach atingiu 0,81 e o Índice de Validade de Conteúdo 88,27 os quais foram empregados para avaliar a consistência interna da versão final da FATCOD-B scale, obtendo-se valor adequado. A versão brasileira da FATCOD-B scale (FATCOD-B-B), traduzida e adaptada transculturalmente para o português brasileiro através de processos científicos rigorosos, apresentou validade de conteúdo e alta consistência interna, logo poderá ser aplicada em todo território nacional.

Abstract: This is a methodological study, with the objective of performing the translation and crosscultural adaptation of the Frommelt Attitude Toward Care of the Dying Scale Form B (FATCOD-B scale) into Brazilian Portuguese and the evaluation of its content validity and internal consistency. This scale is a measurement instrument, which favors the effectiveness of the assistance provided by the health team on the theme of death. It was designed by the nurse Katherine Helen Murray Frommelt in 1989, with the objective of evaluating the attitudes of nurses in relation to the care of terminally ill people and their families. Later, its application was extended to other healthcare professionals, such as physicians. This study was approved by the Ethics Committee on Human Research of the Health Sciences Sector of the Federal University of Paraná with CAEE 55547522.1.0000.0102. It was developed between July 2021 and January 2023, in the online format and involved the following stages: translation; synthesis; back translation; review by a committee of experts; pre-test and final version of the scale. The study participants were recruited as: translators sworn; a translator in the health area; North American back-translators; specialists, among which there are physicians, nurses and a professional graduated in Portuguese-English letters and physicians and nurses associated with the Brazilian Society of Geriatrics and Gerontology who participated in the pre-test. All participants were selected through pre-established inclusion and exclusion criteria. The version of the FATCOD-B scale finalized by the specialists was applied in the pre-test to 75 physicians and 12 nurses, who also answered a sociodemographic questionnaire that contained questions regarding sex, age, religion, profession, previous education about dying and death, previous experience with the loss, present experience with the loss and previous experience in caring for people with terminal illnesses. To evaluate the associations between the answers of the FATCOD-B scale, it was used the chi-square test or Fisher's exact test. All tests were performed considering a 5% significance level and using the R.4.1.2 programming language. From the 87 participants, 57.4% were up to 45 years old; 66.7% were women; 55.2% were catholic; 73.6% pointed to religious belief as a generator of attitudes about dying and death; 96.6% had previous experience in caring for people with terminal illnesses, 72.43% had experienced the loss of close family members or another significant person, 65.5% had not taken a specific course on dying and death, but had the subject approached in other courses. It was observed that the variables age, gender, religion, previous experience with loss and previous education about dying and death are influential in the attitudes towards dying and death (p<0.05). Participants showed positive attitudes towards dying and death, scoring 121 ± 0.68 on the FATCOD-B scale. Cronbach's alpha reached 0.81 and the Content Validity Index 88.27, wich were used to assess the reliability and internal consistency of the final version of the FATCOD-B scale, obtaining adequate values. The Brazilian version of the FATCOD-B scale, translated and cross-culturally adapted through rigorous scientific processes, showed content validity and high internal consistency, and could soon be applied throughout the country.

Cross-cultural adaptation and validation of Sarcopenia and Quality of Life (SarQoL) in Brazil

ABSTRACT BACKGROUND: Sarcopenia is defined as a slow, progressive, and apparently inevitable process of involuntary loss of muscle mass, strength, and quality, which occurs with advancing age. It is widely accepted that sarcopenia can directly affect quality of life. OBJECTIVE: Translate, adapt and validate the "Sarcopenia and Quality of Life" instrument (SarQoL) to the Brazilian context. DESIGN AND SETTINGS: Translation, cross-cultural adaptation, and validation study carried out at the Federal University of São Carlos, São Carlos, São Paulo, Brazil. METHODS: The population consisted of 221 older adult participants. The steps recommended by the guidelines from the authors of the original instrument were followed sequentially: initial translation, synthesis of translations, backward translation, evaluation by a panel of judges, pre-test, and analysis of psychometric properties. The translation and adaptation process was conducted as recommended. RESULTS: Two hundred and twenty-one participants took part in the step analysis of the psychometric properties of SarQoL, in which 55 presented sarcopenia. Cronbach's alpha coefficient of the total SarQoL questionnaire was 0.976, indicating excellent internal consistency. Excellent agreements between the test and retest with an Interclass Correlation Coefficient (ICC) of 0.983 (95% confidence interval: 0.901-0.996) were observed in the SarQoL domains. The domains of Short-Form 36 and EuroQoL 5-dimension showed significant correlation, from moderate to strong magnitude, with SarQoL total score, indicating convergent validity. CONCLUSION: The Brazilian version of SarQoL presented evidence of reliability and validity.

Application of Trados software in the English translation of Chinese patent medicine instructions / 中国药房

OBJECTIVE To standardize the English translations of the current Chinese patent medicine （CPM） instructions in order to increase its English translation quality and improve its readability. METHODS In an attempt to standardize its English translation， 64 CPM instructions were collected as samples for translation projects in Trados， using its two core functions of translation memory and terminology， combined with pre-editing （PRE） and post-editing （PE） skills. RESULTS The results showed that translation projects had up to 21.65% perfect match. Based on translation project practice， it is proposed to use the free translation or transcreation plus transliteration method to translate product names of CPM， and apply two human-computer interaction translation modes：“ machine translation （MT）+computer-assisted translation （CAT）+PE” and “PRE+MT+CAT+PE”， which are adopted in the translation of weak literary sections and strong literary sections， respectively. CONCLUSIONS The application of CAT not only improves the translation quality and the translation mode， reduces the translation cost， and maintains the consistency and style of the translation， but also accumulates language assets for future use， providing a novel reference for translating traditional Chinese medicine literature.

Exploration and practice of the scientific and technological achievements translation at university affiliated hospitals / 中华医院管理杂志

As an important element of medical and health sector innovation, the translation of scientific and technological achievements plays a key role in promoting their clinical application and meeting the medical needs of the people. The authors sorted out the problems in such translation at these affiliated hospitals in terms of " people", " finance", " material", and " system". Starting from 2017, the Tenth People′s Hospital Affiliated to Tongji University has explored such practices as establishing hospital-led clinical medical science and technology innovation parks and technology service limited companies. These practices aimed to address the issues of insufficient hospital scientific and technological innovation capabilities and the gap between the hospital′s operation mechanism to translate its scientific and technological achievements and the enterprises and the market. The clinical medical science and technology innovation park integrating administration, industry, education, research, medicine and application, has taken multiple measures to attract excellent research talents and projects from within and beyond the hospital, promote the implementation of innovative scientific research projects. The hospital also established a health industry mode with engagement of social capital from large enterprises. The Technology Services Co., Ltd. was based on the incubation and translation of hospital achievements, combining market and clinical needs, promoting multi-party cooperation between hospitals and external enterprises, improving the chain operation mechanism of hospital scientific and technological achievements translation work, and alleviating the problem of insufficient research pilot funds and productibility funds by means of hospital-led fundraising. The number of patent authorizations of hospitals had increased from 23 cases in 2018 to 105 in 2022, and the amount of patent conversion had increased from 2 million yuan in 2020 to 11 million yuan in 2022. It is recommended that affiliated hospitals of universities further improve the organizational structure of achievement translation, strengthen their professional talent teams, improve their operation mechanism of achievement translation, build a platform for medical school-enterprise cooperation, and improve the evaluation mechanism of translation assessment, in order to promote a virtuous cycle of hospital′s scientific and technological achievement translation work.
