Abstract Toll-like receptor 9 (TLR9) is an important component of the innate immune system and have been associated with several autoimmune diseases, such as Systemic Lupus Erythematosus (SLE). The aim of this study was to investigate polymorphisms in TLR9 gene in a Brazilian SLE patients group and their association with clinical manifestation, particularly Jaccoud's arthropathy (JA). We analyzed DNA samples from 204 SLE patients, having a subgroup of them presenting JA (n=24). A control group (n=133) from the same city was also included. TLR9 single nucleotide polymorphisms (SNPs) (−1237 C>T and +2848 G>A) were identified by sequencing analysis. The TLR9 gene genotype frequency was similar both in SLE patients and the control group. In the whole SLE population, an association between the homozygosis of allele C at position −1237 with psychosis and anemia (p < 0.01) was found. Likewise, the homozygosis of allele G at position +2848 was associated with a discoid rash (p < 0.05). There was no association between JA and TLR9 polymorphisms. These data show that TLR9 polymorphisms do not seem to be a predisposing factor for SLE in the Brazilian population, and that SNPs are not associated with JA.

Resumo O receptor Toll-like 9 (TLR9) é um componente importante do sistema imunológico inato e tem sido associado a várias doenças autoimunes, como o Lúpus Eritematoso Sistêmico (LES). O objetivo deste estudo foi investigar polimorfismos no gene TLR9 em um grupo de pacientes brasileiros com LES e sua associação com a manifestação clínica, particularmente a artropatia de Jaccoud (JA). Foram analisadas amostras de DNA de 204 pacientes com LES, e um subgrupo com JA (n=24). Um grupo de controle (n=133) da mesma cidade também foi incluído. Os polimorfismos de nucleotídeos únicos TLR9 (SNPs) (−1237 C>T e +2848 G>A) foram identificados pela análise de sequenciamento. A frequência do genótipo genético TLR9 foi semelhante tanto em pacientes com LES quanto no grupo controle. Em toda a população de LES, foi encontrada associação entre a homozigose do alelo C na posição −1237 com psicose e anemia (p < 0,01). Da mesma forma, a homozigose do alelo G na posição +2848 foi associada a uma erupção cutânea discoide (p < 0,05). Não houve associação entre polimorfismos JA e TLR9. Esses dados mostram que os polimorfismos TLR9 não parecem ser um fator predisponível para o LES na população brasileira, e que os SNPs não estão associados ao JA.

ABSTRACT Objectives: The purpose of our study was to assess the association between the winter season and desmopressin treatment failure in South Chinese children with monosymptomatic nocturnal enuresis (MNE). Materials and Methods: A retrospective study was conducted to analyze the clinical data of children with monosymptomatic nocturnal enuresis who have visited our urology clinic from January to December 2019. All patients received desmopressin treatment. Final treatment outcomes were categorized as successful (complete response) or failed (absent and partial response). The relationship between winter season and treatment response to desmopressin was evaluated. Additionally, associated risk factors were investigated with both univariate and multivariate regression analysis. Results: In total, 393 patients diagnosed with MNE were included in the present study. There were no statistically significant differences in pretreatment variables at first visit between patients who visited the clinic in winter and those who did so in other seasons. However, the treatment failure rate of MNE in the winter season was higher than that of other seasons (77.50% vs. 52.74%). Multivariate logistic regression analysis demonstrated that the severity of symptoms and an initial clinic visit in the winter season were significantly related to desmopressin treatment failure in MNE patients. Conclusion: Winter season and severity of symptoms are two risk factors associated with desmopressin treatment failure in MNE patients.

Abstract Background: The implementation of Telecardiology in primary care in the city of Porto Alegre, Brazil, is a viable and promising strategy. It would decrease the distance between patient and specialized professional services by reducing unnecessary referrals and improving the quality of primary care and satisfaction of patients and health professionals. Objective: To implement a Telecardiology service and assess user satisfaction using the CARDIOSATIS scale. Methods: This was a pilot study developed by a partnership between the Institute of Cardiology and the Telehealth Center of Rio Grande do Sul. The study was carried out at Eri Flores-Vila Vargas health center in the city of Porto Alegre, from May to October 2019, and included 21 patients attending the health center. The descriptive analysis of data was performed using the SPSS program (Statistical Package for the Sciences) version 23. Data normality was checked using the Kolmogorov-Smirnov test. Statistical significance was set at 10%. Results: Mean age of participants was 43.8 ± 16.1 years. The most common risk factors in the sample were physical inactivity (81%) and smoking (43%). Most patients had normal electrocardiogram (ECG) readings. The time elapsed from the performance of the ECG test, transmission of the ECG traces to Telehealth, and return of the final ECG report to the health center was 0-7 days. The CARDIOSATIS scale revealed a high prevalence of "very satisfied" users for the general satisfaction domain, and only 14.3% of patients were dissatisfied with their health. Conclusions: Telecardiology reduced the distance between patient and the specialized professional, with a high level of patient and health professional satisfaction. Our study can serve as a basis for the implementation of a telecardiology network in the city of Porto Alegre in the future.

ABSTRACT Purpose: Sperm DNA fragmentation (SDF) and seminal oxidative stress are emerging measurable factors in male factor infertility, which interventions could potentially reduce. We evaluated (i) the impact of lifestyle changes combined with oral antioxidant intake on sperm DNA fragmentation index (DFI) and static oxidation-reduction potential (sORP), and (ii) the correlation between DFI and sORP. Materials and Methods: We conducted a prospective study involving 93 infertile males with a history of failed IVF/ICSI. Ten healthy male volunteers served as controls. Semen analysis was carried out according to 2010 WHO manual, whereas seminal sORP was measured using the MiOXSYS platform. SDF was assessed by sperm chromatin structure assay. Participants with DFI >15% underwent a three-month lifestyle intervention program, primarily based on diet and exercise, combined with oral antioxidant therapy using multivitamins, coenzyme Q10, omega-3, and oligo-elements. We assessed changes in semen parameters, DFI, and sORP, and compared DFI results to those of volunteers obtained two weeks apart. Spearman rank correlation tests were computed for sORP and DFI results. Results: Thirty-eight (40.8%) patients had DFI >15%, of whom 31 participated in the intervention program. A significant decrease in median DFI from 25.8% to 18.0% was seen after the intervention (P <0.0001). The mean DFI decrease was 7.2% (95% CI: 4.8-9.5%; P <0.0001), whereas it was 0.42% (95%CI; -4.8 to 5.6%) in volunteers (P <0.00001). No differences were observed in sperm parameters and sORP. Based on paired sORP and DFI data from 86 patients, no correlation was observed between sORP and DFI values (rho=0.03). Conclusion: A 3-month lifestyle intervention program combined with antioxidant therapy reduced DFI in infertile men with elevated SDF and a history of failed IVF/ICSI. A personalized lifestyle and antioxidant intervention could improve fertility of subfertile couples through a reduction in DFI, albeit controlled trials evaluating reproductive outcomes are needed before firm conclusions can be made. Trial registration number and date: NCT03898752, April 2, 2019.

Estudos mostram que o tabagismo é responsável por afetar algumas funções cognitivas. No entanto, a nicotina é apenas um dos componentes existentes no cigarro e existem evidências de que pode servir como agente neuroprotetivo e causar melhoras em algumas funções cognitivas. O objetivo desta pesquisa foi investigar como a nicotina interage com algumas funções cognitivas. Um ensaio clínico piloto com administração de gomas de nicotina contendo 2-mg ou 4-mg, ou gomas placebo contendo a mesma textura, sabor e aparência, foi realizado. Quarenta e dois participantes participaram da pesquisa e os resultados indicaram que a relação entre nicotina e o desempenho na tarefa Go/No-Go podem ser bidirecionais. Os resultados indicaram que participantes do grupo que utilizaram 4-mg de nicotina apresentaram menor desempenho, enquanto os participantes que fizeram uso de 2-mg de nicotina tiveram melhor desempenho do que os demais. Esta pesquisa tem aplicações biopsicossociais e podem ajudar na compreensão da relação entre tabagismo e nicotina, além de contribuir para estratégias que possam ajudar no abandono do cigarro ou na melhora de condições que afetem a cognição (AU).

Past findings in the literature indicated that smoking could affect given cognitive functions. However, nicotine is only one of the components in cigarettes and there is evidence that it may act as a neuroprotective agent and improve some cognitive functions. The purpose of this research was to investigate how nicotine interacts with certain cognitive functions. We conducted a pilot clinical trial using nicotine gum containing 2-mg or 4-mg, or placebo gum with the same texture, flavor, and appearance. Forty-two healthy nonsmokers were enrolled in this research. Our findings indicated that the relationship between nicotine and performance on the Go/No-Go task might be opposite. The results showed that participants in the 4-mg group performed worse, while participants who used 2-mg of nicotine performed better than the others. This research supports biopsychosocial applications and can help interpret the relationship between smoking and nicotine, and contribute to strategies that may support smoking cessation, or improve conditions that affect cognition (AU).

ABSTRACT Introduction: Currently, no method is considered effective for the evaluation of digital models in the Certification Examination of the Brazilian Board of Orthodontics (BBO), considering the parameters of the currently used manual method. Objective: Thus, the aim of this study is to verify the reliability of an evaluation method for digital models that could be used in the BBO exam, compared to the gold standard. Methods: Measurements were performed by five previously calibrated examiners. Samples of ten sets of plaster models of the final phase of orthodontic treatment were measured using a manual method (Objective Grading System, OGS). These models were digitized using a 3D scanner and exported to Geomagic Qualify software, in which the measurements were made with the proposed digital method. These measurements were repeated using five models, after fifteen days. The intra-examiner performance with this method was analyzed with a paired t-test, whereas the inter-examiner analysis was carried out with analysis of variance and Tukey's test. To compare the manual and digital methods, a paired t-test and Pearson's correlation analysis were performed. Results: A statistically significant difference was found. The results showed that, when compared to the manual method, the digital method was effective in measuring the OGS in four of the seven variables studied: Marginal Ridge, Overjet, Occlusal Contact, and Interproximal Contact. The variables Alignment, BL inclination, and Occlusal Relationship showed a great amount of dispersion in the findings. Conclusion: Further studies are needed to develop an adequate digital methodology that can be used for all OGS variables.

RESUMO Introdução: Ainda não há um método considerado eficaz para análise dos modelos digitais no exame do Board Brasileiro de Ortodontia (BBO), considerando-se os parâmetros do método manual atual. Objetivo: Assim, o presente estudo objetiva verificar a confiabilidade de um método de avaliação em modelos digitais para o exame do BBO, comparando com o padrão-ouro. Métodos: As medições foram realizadas por 5 examinadores, previamente calibrados. A amostra de 10 pares de modelos de gesso da fase final do tratamento ortodôntico foi medida no método manual (Sistema Objetivo de Avaliação, SOA). Os modelos foram digitalizados por meio de um scanner 3D e exportados para o software Geomagic Qualify, onde foram feitas as medidas no método digital proposto. As medidas foram refeitas em 5 modelos após 15 dias. A análise intraexaminador desse método foi realizada por meio do teste t pareado; já a interexaminadores, feita com ANOVA e teste de Tukey, sendo encontrada diferença estatisticamente significativa. Para a comparação dos métodos manual e digital, foram utilizados o teste t pareado e a correlação de Pearson. Resultados: Uma diferença estatisticamente significativa foi encontrada. Os resultados mostraram que, comparada ao método manual, a metodologia digital mostrou-se eficaz para medição do SOA em quatro das sete variáveis estudadas: Margem interproximal, Sobressaliência, Contato oclusal e Contato interproximal. As variáveis Alinhamento, Inclinação V-L e Relação oclusal mostraram muita dispersão nos achados. Conclusão: Mais estudos são necessários para o desenvolvimento de uma metodologia digital adequada em todas as variáveis do SOA.

Resumo Fundamentos Uma metodologia para identificação de pacientes portadores de aneurisma de aorta ascendente (AAAs) sob alto risco de remodelamento aórtico não está completamente definida. Objetivo Esta pesquisa objetiva caracterizar numericamente o fluxo sanguíneo aórtico, relacionando a distribuição do estresse mecânico resultante com o crescimento de AAAs. Métodos Estudo analítico, observacional, unicêntrico, em que um protocolo de fluidodinâmica computacional (CFD - Computacional Fluid Dynamics) foi aplicado a imagens de angiotomografia computadorizada (ATC) de aorta de pacientes portadores de AAAs. Duas ATC de aorta com pelo menos um ano de intervalo foram obtidas. Dados clínicos dos pacientes foram registrados e, a partir das imagens de ATC, foram gerados modelos tridimensionais. Foram realizados estudos do campo de velocidade e estruturas coerentes (vórtices) com o objetivo de relacioná-los ao crescimento ou não do aneurisma e, posteriormente, compará-los com os dados clínicos dos pacientes. O teste de Kolmogorov-Smirnov foi utilizado para avaliar a normalidade da amostra e o teste não-paramétrico Wilcoxon signed-rank foi aplicado para comparações de dados pareados entre os ângulos aórticos. A significância estatística foi fixada em 5%. Resultados Para o grupo que apresentou crescimento do aneurisma, a incidência do jato na parede aórtica gerou áreas de recirculação posterior ao jato, induzindo à formação de vórtices complexos, ocasionando um incremento na pressão média no endotélio aórtico. O grupo sem crescimento do aneurisma apresentou diminuição na pressão média. Conclusão Este estudo piloto mostrou que a CFD baseada em ATC pode, em um futuro próximo, ser uma ferramenta auxiliar na identificação dos padrões de fluxo associados ao processo de remodelamento de AAAs.

Abstract Background A methodology to identify patients with ascending aortic aneurysm (AsAA) under high risk for aortic growth is not completely defined Objetive This research seeks to numerically characterize the aortic blood flow by relating the resulting mechanical stress distribution with AsAA growth. Methods Analytical, observational, single-center study in which a computational fluid dynamics (CFD) protocol was applied to aortic computed tomography angiogram (CTA) images of patients with AsAA. Two CTA exams taken at a minimum interval of one year were obtained. From the CTA-gathered images, three-dimensional models were built, and clinical data were registered. Study of velocity field and coherent structures (vortices) was performed aiming to relate them to the presence or absence of aneurysm growth, as well as comparing them to the patients' clinical data. The Kolmogorov-Smirnov test was used to evaluate the normality of the distribution, and the non-parametric Wilcoxon signed-rank test, for non-normal distribution, was used to compare the paired data of the aortic angles. Statistical significance was set at 5%. Results The incident jet in the aortic wall generated recirculation areas in the posterior region of the jet, inducing complex vortices formation in the group with aneurysm growth, leading to an average pressure increase in the ascending aortic wall between exams. In the group without aneurysm growth, the average pressure decreased. Conclusion This pilot study showed that CFD based on CTA may in the near future be a tool to help identify flow patterns associated with AsAA remodeling process.

ABSTRACT Objective: To assess the feasibility of using a new helmet interface for CPAP, designated ELMO, to treat COVID-19-related acute hypoxemic respiratory failure (AHRF) outside the ICU. Methods: This was a proof-of-concept study involving patients with moderate to severe AHRF secondary to COVID-19 admitted to the general ward of a public hospital. The intervention consisted of applying CPAP via the ELMO interface integrated with oxygen and compressed air flow meters (30 L/min each) and a PEEP valve (CPAP levels = 8-10 cmH2O), forming the ELMOcpap system. The patients were monitored for cardiorespiratory parameters, adverse events, and comfort. Results: Ten patients completed the study protocol. The ELMOcpap system was well tolerated, with no relevant adverse effects. Its use was feasible outside the ICU for a prolonged amount of time and was shown to be successful in 60% of the patients. A CPAP of 10 cmH2O with a total gas flow of 56-60 L/min improved oxygenation after 30-to 60-min ELMOcpap sessions, allowing a significant decrease in estimated FIO2 (p = 0.014) and an increase in estimated PaO2/FIO2 ratio (p = 0.008) within the first hour without CO2 rebreathing. Conclusions: The use of ELMOcpap has proven to be feasible and effective in delivering high-flow CPAP to patients with COVID-19-related AHRF outside the ICU. There were no major adverse effects, and ELMO was considered comfortable. ELMOcpap sessions significantly improved oxygenation, reducing FIO2 without CO2 rebreathing. The overall success rate was 60% in this pilot study, and further clinical trials should be carried out in the future. ( identifier: NCT04470258 [])

RESUMO Objetivo: Avaliar a viabilidade do uso de uma nova interface do tipo capacete para CPAP, denominada ELMO, para o tratamento da insuficiência respiratória aguda (IRpA) hipoxêmica por COVID-19 fora da UTI. Métodos: Estudo de prova de conceito envolvendo pacientes com IRpA hipoxêmica moderada a grave secundária à COVID-19, internados na enfermaria geral de um hospital público. A intervenção consistiu na aplicação de CPAP por meio da interface ELMO integrada a fluxômetros de oxigênio e ar comprimido (30 L/min cada) e a uma válvula de PEEP (níveis de CPAP = 8-10 cmH2O), formando o sistema ELMOcpap. Os pacientes foram monitorados quanto a parâmetros cardiorrespiratórios, eventos adversos e conforto. Resultados: Dez pacientes completaram o protocolo do estudo. O sistema ELMOcpap foi bem tolerado, sem efeitos adversos relevantes. Seu uso foi viável fora da UTI por tempo prolongado e mostrou-se bem-sucedido em 60% dos pacientes. Uma CPAP de 10 cmH2O com fluxo total de gás de 56-60 L/min melhorou a oxigenação após sessões de ELMOcpap de 30-60 min, permitindo redução significativa da FIO2 estimada (p = 0,014) e aumento da PaO2/FIO2 estimada (p = 0,008) na primeira hora, sem reinalação de CO2. Conclusões: O uso do ELMOcpap mostrou-se viável e eficaz no fornecimento de CPAP de alto fluxo a pacientes com IRpA hipoxêmica por COVID-19 fora da UTI. Não houve nenhum efeito adverso importante, e o ELMO foi considerado confortável. As sessões de ELMOcpap melhoraram significativamente a oxigenação, reduzindo a FIO2 sem reinalação de CO2. A taxa global de sucesso foi de 60% neste estudo piloto, e novos ensaios clínicos devem ser realizados. ( identifier: NCT04470258 [])

Resumo Objetivo Avaliar a adesão de gestantes e acompanhantes à realização da massagem perineal digital durante a gestação e seu efeito na prevenção do trauma perineal no parto e na redução de morbidade associada nos 45 e 90 dias pós-parto. Métodos Estudo piloto de ensaio clínico randomizado com 153 gestantes de risco habitual, 78 mulheres no grupo de intervenção realizaram a massagem perineal digital e 75 mulheres do grupo controle receberam os cuidados habituais. Para a análise do desfecho principal (trauma perineal) e dos desfechos secundários, permaneceram em cada grupo 44 mulheres que tiveram parto vaginal. A intervenção foi realizada pela gestante ou acompanhante de sua escolha, diariamente, a partir de 34 semanas de gestação, por 5 a 10 minutos. Resultados A massagem perineal foi fator de proteção para edema nos primeiros 10 dias pós-parto (RR 0,64 IC95%0,41-0,99) e perda involuntária de gases nos 45 dias pós-parto (RR0,57 IC95%0,38-0,86). O ajuste residual ≥ 2 observado na análise das condições do períneo pós-parto mostrou uma tendência das mulheres do grupo intervenção terem períneo íntegro. As mulheres e os acompanhantes que realizaram a massagem perineal aceitaram bem a prática, recomendariam e fariam novamente em futura gestação. Conclusão A massagem perineal digital realizada diariamente, a partir de 34 semanas de gestação, foi uma prática bem aceita pelas mulheres e acompanhantes deste estudo. Apesar de não proteger a mulher de trauma perineal, esta prática reduziu o risco de edema 10 dias pós-parto e incontinência de gases 45 dias pós-parto.

Resumen Objetivo Evaluar la participación de mujeres embarazadas y acompañantes en la realización del masaje digital perineal durante el embarazo y su efecto en la prevención del trauma perineal durante el parto y en la reducción de la morbilidad asociada con los 45 y 90 días post parto. Métodos Estudio piloto de ensayo clínico aleatorizado con 153 mujeres embarazadas con riesgo normal, 78 mujeres en el grupo de intervención realizaron el masaje digital perineal y 75 mujeres del grupo control recibieron los cuidados habituales. Para el análisis del desenlace principal (trauma perineal) y de los desenlaces secundarios, permanecieron en cada grupo 44 mujeres que tuvieron parto vaginal. La intervención la realizó la mujer embarazada o el acompañante por ella elegido, diariamente, a partir de las 34 semanas de embarazo, por 5 a 10 minutos. Resultados El masaje perineal fue factor de protección para el edema en los primeros 10 días postparto (RR 0,64 IC95%0,41-0,99) y la pérdida involuntaria de gases en los 45 días post parto (RR0,57 IC95%0,38-0,86). El ajuste residual ≥ 2 observado en el análisis de las condiciones del perineo postparto mostró una tendencia en las mujeres del grupo intervención a que tengan el perineo íntegro. Las mujeres y los acompañantes que realizaron el masaje perineal recibieron bien la práctica, la recomendarían y la harían nuevamente en un futuro embarazo. Conclusión El masaje digital perineal realizado diariamente, a partir de las 34 semanas de embarazo, fue una práctica bien recibida por las mujeres y acompañantes de este estudio. Pese a que no protege a la mujer de un trauma perineal, esta práctica redujo el riesgo de edema a los 10 días post parto y la incontinencia de gases 45 días post parto.

Abstract Objective To evaluate the adherence of pregnant women and companions to the performance of digital perineal massage during pregnancy and its effect on the prevention of perineal trauma during childbirth and on the reduction of associated morbidity at 45 and 90 days postpartum. Methods A pilot study of a randomized clinical trial with 153 normal risk pregnant women; 78 women in the intervention group underwent digital perineal massage and 75 women in the control group received usual care. For the analysis of the main outcome (perineal trauma) and secondary outcomes, 44 women who had vaginal delivery remained in each group. The intervention was performed daily by the pregnant woman or the companion of her choice from 34 weeks of gestation during 5-10 minutes. Results Perineal massage was a protective factor for edema in the first 10 days postpartum (RR 0.64 95%CI 0.41-0.99) and involuntary gas loss at 45 days postpartum (RR0.57 95%CI 0.38-0.86). The residual adjustment ≥ 2 observed in the analysis of perineal conditions postpartum showed a trend of women in the intervention group having an intact perineum. The women and companions who performed perineal massage accepted the practice well, recommended it and would do it again in a future pregnancy. Conclusion The digital perineal massage performed daily from 34 weeks of gestation was a practice well accepted by women of this study and their companions. Although not protecting women from perineal trauma, this practice reduced the risk of edema at 10 days postpartum and gas incontinence at 45 days postpartum.

OBJECTIVES@#To study the significance of interleukin-6 (IL-6) and interleukin-27 (IL-27) in the differential diagnosis of acute respiratory distress syndrome (ARDS) and neonatal respiratory distress syndrome (NRDS) in preterm infants.@*METHODS@#The preterm infants with the manifestation of respiratory distress who were treated in the Neonatal Diagnosis and Treatment Center, Children's Hospital of Chongqing Medical University, from March to November 2021, were enrolled in this prospective study. According to the diagnosis results, they were divided into two groups: ARDS group (n=18) and NRDS group (n=20). ELISA was used to measure the plasma levels of IL-6 and IL-27. The receiver operating characteristic (ROC) curve was used to analyze the value of each index in the diagnosis of ARDS.@*RESULTS@#The ARDS group had significantly higher plasma levels of IL-6 and IL-27 than the NRDS group (P<0.05). The ROC curve analysis showed that IL-6 had an area under the ROC curve (AUC) of 0.867 for the diagnosis of ARDS, with a sensitivity of 61.1% and a specificity of 95.0% at the cut-off value of 56.21 pg/mL. The ROC curve analysis also showed that IL-27 had an AUC of 0.881 for the diagnosis of ARDS, with a sensitivity of 83.3% and a specificity of 80.0% at the cut-off value of 135.8 pg/mL.@*CONCLUSIONS@#Plasma IL-6 and IL-27 can be used as biological indicators for early differential diagnosis of ARDS and NRDS in preterm infants.

INTRODUCTION@#This study aimed to evaluate the potential of non-contrast-enhanced magnetic resonance (MR) imaging as an imaging surveillance tool for detection of hepatocellular carcinoma (HCC) in at-risk patients and to compare the performance of non-contrast MR imaging with ultrasonography (US) as a screening modality for the same.@*METHODS@#In this retrospective study, patients diagnosed with HCC between 1 January 2010 and 31 December 2015 were selected from our institution's cancer registry. Patients who underwent MR imaging and had US performed within three months of the MR imaging were included. For each MR imaging, two non-contrast MR imaging sequences - T2-weighted fat-saturated (T2-W FS) sequence and diffusion-weighted imaging (DWI) - were reviewed for the presence of suspicious lesions. A non-contrast MR image was considered positive if the lesion was seen on both sequences. The performance of non-contrast MR imaging was compared to that of hepatobiliary US for the detection of HCC.@*RESULTS@#A total of 73 patients with 108 HCCs were evaluated. Sensitivity of non-contrast MR imaging for the detection of HCC using T2-W FS and DWI was 93.2%, which was significantly higher than that of US, which was 79.5% (p = 0.02). In a subgroup of 55 patients with imaging features of liver cirrhosis, the sensitivity of non-contrast MR imaging was 90.9%, which was also significantly higher than that of US, which was 74.5% (p = 0.02).@*CONCLUSION@#Our pilot study showed that non-contrast MR imaging, using a combination of T2-W FS and DWI, is a potential alternative to US as a screening tool for surveillance of patients at risk for HCC.

INTRODUCTION@#Linkage to care among individuals with substance misuse remains a barrier to the elimination of the hepatitis C virus (HCV). We aimed to determine whether point-of-care (PoC) education, screening and staging for liver disease with direct access to hospitals would improve linkage to care among this group. @*METHODS@#All participants were offered PoC education and HCV screening. HCV-positive participants were randomised to standard care (controls) or direct access, which provided a direct pathway to hospitals. Linkage to care was determined by reviewing electronic medical records. Linkage of care cascade was defined as attendance at the specialist clinic, confirmation of viraemia by HCV RNA testing, discussion about HCV treatment and initiation of treatment. @*RESULTS@#351 halfway house residents were screened. The overall HCV prevalence was 30.5% (n = 107), with 69 residents in the control group and 38 in the direct access group. The direct access group had a significantly higher percentage of cases linked to specialist review for confirmatory RNA testing (63.2% vs. 40.6%, p = 0.025), HCV treatment discussion (p = 0.009) and treatment initiation (p = 0.01) compared to the controls. Overall, only 12.6% (n = 13) had treatment initiation during follow-up. PoC HCV screening with direct access referral had significantly higher linkage to HCV treatment initiation (adjusted odds ratio 9.13, p = 0.005) in multivariate analysis. @*CONCLUSION@#PoC HCV screening with direct access improves linkage to care and simplifies the HCV care cascade, leading to improved treatment uptake. PoC education, screening, diagnosis and treatment may be an effective strategy to achieving HCV micro-elimination in this population.

Introducción. El mobiliario escolar influye en la postura sedente que adopta el alumnado en el aula, con efectos en su salud y aprendizaje. Por ello, es preciso determinar la existencia de un posible desajuste entre las dimensiones del mobiliario escolar y la antropometría del alumnado, así como realizar una propuesta de tallas en base a la realidad del aula y las normativas de Galicia y la Unión Europea. Población y métodos. Un evaluador experto en antropometría realizó las mediciones de peso, talla, altura poplítea, hombro y codo sentado, con un antropómetro, comparándolas posteriormente con las sillas y mesas utilizadas actualmente. Las técnicas de análisis empleadas fueron: descriptivo (medidas de tendencia central), análisis de la varianza de un factor, prueba t, prueba de chi cuadrado (en software SPSS®) y tamaño del efecto (d de Cohen). El nivel de significación establecido fue de p ≤ 0,05. Resultados. La muestra se compuso de 108 estudiantes españoles de educación primaria (de entre 6 y 12 años). El 91,7 % y el 97,2 % del alumnado emplea, respectivamente, una silla y una mesa que no se ajusta a sus características antropométricas, y utiliza mobiliario con un tamaño superior al que le corresponde. La normativa de tallas de mobiliario que rige actualmente en la población estudiada no es apropiada, al no tener sillas y mesas adecuadas a los primeros cursos de primaria. Conclusiones. Existe un alto grado de desajuste entre el mobiliario y la antropometría del alumnado. Se propone seguir las tallas de la normativa europea, utilizando varias tallas por curso o mobiliario regulable, para adaptarse a las características antropométricas de todo el alumnado.

Introduction. School furniture affects the sitting position of students in the classroom, as well as their health and learning. Therefore, it is necessary to determine the existence of a potential mismatch between school furniture dimensions and students' anthropometric characteristics, as well as to propose dimensions based on classroom actuality and the regulations in place in both Galicia and the European Union. Population and methods. An evaluator with experience in anthropometry measured weight, height, popliteal height, sitting shoulder height, and sitting elbow height using an anthropometer and then compared values with the chairs and desks currently used. Analysis techniques were descriptive (measures of central tendency), single-factor analysis of variance, t test, χ² test (using the SPSS® software), and effect size (Cohen's d test). The significance level was established at p ≤ 0.05.Results. The sample was made up of 108 Spanish children in primary school (aged 6-12 years). Of them, 91.7 % and 97.2 % use, respectively, a chair and a desk that do not adjust to their anthropometric characteristics and use furniture that is larger than what they need. The regulations for furniture dimensions currently in place for the studied population are not adequate because the chairs and desks included are not adequate for the first grades of primary school. Conclusions. There is a high mismatch level between school furniture and students' anthropometric characteristics. We propose the use of the European regulations for furniture dimensions, with varying heights per grade or adjustable furniture that can be adapted to the anthropometric characteristics of all students.

Abstract Introduction: The outcomes of Acute Kidney Injury (AKI) remain dismal even today, owing in part due to the lack of an ideal biomarker for detecting renal damage early enough. We conducted this pilot study to determine the clinical significance of Frusemide Stress Test (FST) to predict the severity of AKI. Methods: A total of 80 patients with AKI-KDIGO (Kidney Disease: Improving Global Outcomes) stage 1 or stage 2 underwent FST by administering a bolus dose of frusemide (1mg/kg for frusemide naïve and 1.5mg/kg for prior frusemide exposure in the past week), and urine output was then measured for the next two hours with volume replacement as desirable. The progression to AKI-KDIGO stage 3 within 14 days of FST was studied as the primary outcome. The composite end point of achieving AKI-KDIGO stage 3 or death within 14 days of FST was studied as the secondary outcome. Results: Out of 80 patients, 28(35%) patients met the primary outcome, and 34(42.5%) patients met the secondary composite outcome. Except for baseline Chronic Kidney Disease (CKD) status (p=0.018), other demographic characteristics were comparable between progressors and non-progressors group. Using receiver operating characteristics (ROC) curve analysis, a cumulative 2-hour post-FST urine output of ≤300 mL predicted progression to stage 3 AKI with 82.14% sensitivity, 82.69% specificity, and AUC of 0.89±0.03 (p<0.0001). Conclusion: The FST showed promising results as a novel tubular biomarker to identify progression to severe AKI with good predictive ability.

Resumo Introdução: Os desfechos da Lesão Renal Aguda (LRA) permanecem desanimadores ainda hoje, em parte pela falta de um biomarcador ideal para detectar danos renais com a devida antecedência. Realizamos este estudo piloto para determinar a importância clínica do Teste de Estresse com Furosemida (TEF) em prever a gravidade da LRA. Métodos: Um total de 80 pacientes com LRA-KDIGO estágio 1 ou 2 foram submetidos ao TEF pela administração de uma dose em bolus de furosemida (1mg/kg para pacientes virgens de furosemida e 1,5mg/kg para exposição prévia à furosemida na semana anterior). O débito urinário foi então medido durante as duas horas seguintes com reposição de volume conforme desejável. A progressão para LRA-KDIGO estágio 3 dentro de 14 dias de TEF foi estudada como principal desfecho. O desfecho composto de atingir a LRA-KDIGO estágio 3 ou óbito em 14 dias após TEF foi estudado como desfecho secundário. Resultados: Dos 80 pacientes, 28 (35%) atingiram desfecho primário, e 34 (42,5%) pacientes atingiram o desfecho composto secundário. Exceto pelo estado basal da Doença Renal Crônica (DRC) (p=0,018), outras características demográficas foram comparáveis entre o grupo progressores e não progressores. Usando a análise da Curva Característica de Operação do Receptor (ROC), um débito urinário cumulativo de 2 horas pós-TEF de ≤300 mL previu a progressão para estágio 3 da LRA com 82,14% de sensibilidade, 82,69% de especificidade, e AUC de 0,89±0,03 (p<0,0001). Conclusão: O TEF mostrou resultados promissores como novo biomarcador tubular para identificar progressão para LRA grave com boa capacidade preditiva.

O aumento da população idosa mundial em torno de 600% nos últimos 50 anos trouxe vários desafios. O principal é a adoção de políticas que possam oferecer um envelhecimento saudável, preservando a autonomia dos sujeitos. Entre essas estratégias, a estimulação cognitiva é uma que possui baixo custo operacional e pode otimizar as funções que ainda se encontram preservadas. O objetivo desse estudo piloto retrospectivo foi avaliar o impacto protetivo das práticas de estimulação cognitiva em octogenários da cidade de São João del Rei. Para tanto foram aplicados dois instrumentos de avaliação: o Mini-Mental e um Questionário de Práticas Cognitivas. Os resultados preliminares indicam uma tendência de as práticas cognitivas impactarem positivamente no desempenho no Mini-Mental dos octogenários (p<0.01). Tais resultados têm implicações diretas, sobretudo nas estratégias de baixo custo a serem implementadas com o objetivo de se construírem reservas cognitivas na população recém adentrada na 3ª idade, visando uma maior autonomia na 4ª idade.

The increase in the world's elderly population of around 600% in the last 50 years has brought many challenges. The main one is adopting policies that can offer healthy aging, preserving the subjects' autonomy. Among these strategies, the cognitive stimulation is one that has a low operational cost and can optimize the functions which are still preserved. This retrospective pilot study aimed at evaluating the impact of cognitive stimulation practices on octogenarian elderly in the city of São João del Rei. Therefore, two evaluation instruments were applied: Mini-Mental and a Cognitive Practice Questionnaire. The preliminary results indicate a tendency that the cognitive practices impact positively on the octogenarians' cognitive performance(p<0.01). Such results have direct implications especially on the low-coststrategies to be implemented aiming at building cognitive reserves in the population of the recent 3rd age viewing a bigger autonomy in the 4th age.

Introducción. El asma es una de las enfermedades crónicas más frecuentes en niños. Múltiples estudios han sugerido que en la infancia presenta una asociación significativa con los trastornos respiratorios del sueño, con una prevalencia en niños asmáticos de un 24%. El objetivo fue determinar la prevalencia de trastornos respiratorios del sueño (TRS) en pacientes con asma controlados en un hospital pediátrico (6-15 años). Pacientes y Método. Estudio transversal descriptivo. Se aplicaron los cuestionarios de sueño pediátrico validado en español (pediatric sleep questionnaire, PSQ) y el Cuestionario de Control del Asma en Niños (CAN) a los padres de los niños con diagnósticos de asma controlados en Hospital Roberto del Río, vía telefónica y vía email. Resultados: La prevalencia de TRS fue de 34,8%. Un 20% presenta mal control de asma definido como CAN >8. Un 58,1% de los padres reportaron sobrepeso en los pacientes Conclusiones: la prevalencia de TRS en los niños estudiados es alta y obliga a investigar en cada consulta por estos síntomas. Aplicar la encuesta en cada consulta, de forma online podría aportar al conocimiento de estos pacientes y mantener la prevalencia del problema actualizada, para focalizar las intervenciones apropiadas.

Abstract Introduction: Rapid prototyping is a process by which three-dimensional (3D) computerized surface models are converted into physical models. In this study, a 3D heart bio model was created using the rapid prototyping method and the accuracy of this heart model was assessed by clinicians. Methods: The two-dimensional images of normal heart from gated computed tomography scan datasets were used to create a 3D model of the heart. The slices were then processed using the software BioModroid and printed with the 3D printer. The evaluation of the model was performed by a questionnaire answered by four cardiothoracic surgeons, 12 cardiologists, five radiologists, and nine surgical registrars. Results: Eighty-six percent of the anatomy structures showed in this model scored 100% accuracy. Structures such as circumflex branch of left coronary artery, great cardiac vein, papillary muscle, and coronary sinus were each rated 77%, 70%, 70%, and 57% accurate. Among 30 clinicians, a total of 93% rated the model accuracy as good and above; 64% of the clinicians evaluated this model as an excellent teaching tool for anatomy class. As a visual aid for surgery or interventional procedures, the model was rated excellent (40%), good (50%), average (23%), and poor (3%); 70% of the clinicians scored the model as above average for training purpose. Overall, this 3D rapid prototyping cardiac model was rated as excellent (33%), good (50%), and average (17%). Conclusion: This 3D rapid prototyping heart model will be a valuable source of anatomical education and cardiac interventional management.
