RESUMO A introdução da soja tolerante a 2,4-D (ENLIST®) oferece um novo potencial para a aplicação de herbicidas. Dessa forma, o presente trabalho teve como objetivo: (a) avaliar o efeito das combinações de herbicidas pós-emergentes no controle de Conyza spp., e (b) a seletividade da associação de herbicidas pós-emergentes em soja, garantindo uma aplicação eficaz sem comprometer a saúde da cultura. Um experimento de campo com soja tolerante ao 2,4-D utilizou um delineamento experimental de blocos casualizados, com 14 tratamentos em quatro repetições. Os tratamentos incluíram várias combinações de 2,4-D com glifosato, chlorimuron, cloransulam, imazethapyr, bentazona e imazamox. Estes foram aplicados como um único tratamento ou sequencialmente 15 dias após o tratamento (DAT) usando glufosinato de amônio, juntamente com dois controles sem aplicação de herbicida. Os resultados mostraram menos de 15% de fitotoxicidade em todos os tratamentos. Aos 21 DAT, apenas os tratamentos aplicados sequencialmente mostraram controle significativo, com eficácia superior a 80% contra Conyza spp. Em contraste, as aplicações únicas das combinações de herbicidas com 2,4-D foram ineficazes para o controle pós-emergência de Conyza spp. 2,4D 24D D 2,4 2 4 ENLIST® ENLIST (ENLIST® forma objetivo (a pósemergentes pós emergentes spp b (b cultura casualizados 1 repetições glifosato chlorimuron cloransulam imazethapyr imazamox DAT (DAT amônio herbicida significativo 80 contraste pósemergência emergência 4D 24 2, (ENLIST 8

ABSTRACT The introduction of 2,4-D-tolerant soybeans (ENLIST®) offers a new potential for herbicide application. Therefore, the present study aimed to (a) evaluate the effect of combinations of post-emergent herbicides on the control of Conyza spp. and (b) assess the selectivity of the post-emergent herbicide association in soybeans, ensuring effective application without compromising the health of the crop. A field experiment with 2,4-D-tolerant soybeans utilized a randomized complete block design with 14 treatments across four replications. Treatments included various combinations of 2,4-D with glyphosate, chlorimuron-ethyl, cloransulam-methyl, imazethapyr, bentazon, and imazamox. These were applied either as a single treatment or sequentially 15 days after treatment (DAT) using glufosinate-ammonium alongside two controls without herbicide application. The results showed less than 15% control across all treatments. At 21 DAT, only the treatments applied sequentially showed significant control, with effectiveness exceeding 80% against Conyza spp. In contrast, the single applications of the herbicide combinations with 2,4-D were ineffective for post-emergence control of Conyza spp. 2,4Dtolerant 24Dtolerant Dtolerant 2,4 D tolerant 2 4 ENLIST® ENLIST (ENLIST® Therefore (a postemergent post emergent spp b (b crop 1 replications 2,4D 24D glyphosate chlorimuronethyl, chlorimuronethyl chlorimuron ethyl, ethyl chlorimuron-ethyl cloransulammethyl, cloransulammethyl cloransulam methyl, methyl cloransulam-methyl imazethapyr bentazon imazamox DAT (DAT glufosinateammonium glufosinate ammonium 80 contrast postemergence emergence 4Dtolerant 24 2, (ENLIST 4D 8

RESUMO Introdução: Doenças pulmonares são comuns em pacientes com doença renal em estágio terminal (DRET), dificultando o diagnóstico diferencial com COVID-19. Este estudo descreve achados de tomografia computadorizada de tórax (TC) em pacientes com DRET em terapia renal substitutiva (TRS) hospitalizados com suspeita de COVID-19. Métodos: Indivíduos maiores de 18 anos com DRET, encaminhados ao pronto-socorro com suspeita de COVID-19 foram incluídos. Dados clínicos e epidemiológicos foram extraídos de registros eletrônicos de saúde. A TC foi classificada como típica, indeterminada, atípica, negativa. Comparamos achados tomográficos de pacientes com COVID-19 positivos e negativos. Resultados: Recrutamos 109 pacientes (62,3% COVID-19-positivos) entre março e dezembro de 2020, idade média de 60 ± 12,5 anos, 43% mulheres. A etiologia mais comum da DRET foi diabetes. Tempo médio em diálise foi 36 meses, intervalo interquartil = 12–84. A lesão pulmonar mais comum foi opacidades em vidro fosco. O padrão típico de TC foi mais comum em pacientes com COVID-19 (40 (61%) vs. 0 (0%) em pacientes sem COVID-19, p < 0,001). Sensibilidade 60,61% (40/66), especificidade 100% (40/40). Valores preditivos positivos e negativos foram 100% e 62,3%, respectivamente. Padrão atípico de TC foi mais frequente em pacientes COVID-19-negativos (9 (14%) vs. 24 (56%) em COVID-19-positivos, p < 0,001), enquanto padrão indeterminado foi semelhante em ambos os grupos (13 (20%) vs. 6 (14%), p = 0,606), e padrão negativo foi mais comum em pacientes COVID-19-negativos (4 (6%) vs. 12 (28%), p = 0,002). Conclusões: Em pacientes com DRET em TRS hospitalizados, um padrão atípico de TC de tórax não pode excluir adequadamente o diagnóstico de COVID-19. Introdução , (DRET) COVID19.

ABSTRACT Introduction: Lung diseases are common in patients with end stage kidney disease (ESKD), making differential diagnosis with COVID-19 a challenge. This study describes pulmonary chest tomography (CT) findings in hospitalized ESKD patients on renal replacement therapy (RRT) with clinical suspicion of COVID-19. Methods: ESKD individuals referred to emergency department older than 18 years with clinical suspicion of COVID-19 were recruited. Epidemiological baseline clinical information was extracted from electronic health records. Pulmonary CT was classified as typical, indeterminate, atypical or negative. We then compared the CT findings of positive and negative COVID-19 patients. Results: We recruited 109 patients (62.3% COVID-19-positive) between March and December 2020, mean age 60 ± 12.5 years, 43% female. The most common etiology of ESKD was diabetes. Median time on dialysis was 36 months, interquartile range = 12–84. The most common pulmonary lesion on CT was ground glass opacities. Typical CT pattern was more common in COVID-19 patients (40 (61%) vs 0 (0%) in non-COVID-19 patients, p < 0.001). Sensitivity was 60.61% (40/66) and specificity was 100% (40/40). Positive predictive value and negative predictive value were 100% and 62.3%, respectively. Atypical CT pattern was more frequent in COVID-19-negative patients (9 (14%) vs 24 (56%) in COVID-19-positive, p < 0.001), while the indeterminate pattern was similar in both groups (13 (20%) vs 6 (14%), p = 0.606), and negative pattern was more common in COVID-19-negative patients (4 (6%) vs 12 (28%), p = 0.002). Conclusions: In hospitalized ESKD patients on RRT, atypical chest CT pattern cannot adequately rule out the diagnosis of COVID-19.

Abstract The prevalence of openly trans and non-binary people has been increasing, and, in today's world, it is estimated that they represent 0.39% and 1.19% of the global population, respectively. Thus, it becomes increasingly imperative that primary health care physicians are prepared to receive and guide this population, in their general and specific health needs. In this sense, this work intends to study the knowledge of health professionals and their approach to trans and non-binary people in the primary care facilities associated with Centro Hospitalar Universitário do Porto, via an online questionnaire that was sent to the population under study. It was found that, although there is significant contact between residents and specialists in general and family medicine with trans and non-binary people in clinical practice, the perceived degree of knowledge and training about the specific needs of this population seems to be extremely small. It is, therefore, crucial to invest in pre-graduate training, as well as post-graduate training.

Resumo A prevalência de pessoas assumidamente trans e não binárias tem vindo a aumentar, sendo que no mundo hodierno estima-se representarem 0,39% e 1,19% da população mundial, respetivamente. Deste modo, torna-se cada vez mais imperativo que os cuidados de saúde primários estejam preparados para receber e orientar esta população nas suas necessidades de saúde gerais e específicas. Neste sentido, este trabalho pretende estudar o conhecimento dos profissionais de saúde e a sua abordagem aos utentes trans e não binários nas Unidades de Saúde Familiar adstritas ao Centro Hospitalar Universitário do Porto, tendo sido enviado um questionário online à população em estudo. Constatou-se que, embora exista um significativo contacto entre médicos internos e especialistas de medicina geral e familiar com pessoas trans e não binárias na prática clínica, o grau percecionado de conhecimentos e de formação acerca das necessidades específicas desta população parece ser extremamente diminuto. É, assim, fulcral o investimento na formação pré-graduada, bem como na formação pós-graduada.

Resumo A síndrome hemolítica-urémica mediada por complemento (SHUc) é uma síndrome rara, que atinge predominantemente crianças e jovens adultos e surge por defeitos na regulação da cascata do complemento. Apresentamos o caso de uma doente que se apresenta com quadro de náuseas, vómitos, dor abdominal difusa, dejeções e colúria com três dias de evolução. Analiticamente com sinais de anemia hemolítica microangiopática, trombocitopenia e lesão renal, foi internada para estudo. Inicialmente sob terapêutica com permuta plasmática e corticoterapia, sem melhoria clínica ou analítica. Após estudo exaustivo, e excluídos diagnósticos mais prováveis, assumido diagnóstico de SHUc tendo iniciado terapêutica dirigida com eculizumab com recuperação sustentada.

Abstract Complement-mediated hemolytic uremic syndrome (cHUS) is a rare syndrome that predominantly affects children and young adults and arises from defects in the regulation of the complement cascade. We present the case of a patient who presented with a clinical picture of nausea, vomiting, diffuse abdominal pain, diarrhea, and dark urine with three days of evolution. Analytically, there were signs of microangiopathic hemolytic anemia, thrombocytopenia, and renal injury, and the patient was admitted for study. Initially treated with plasmapheresis and corticosteroids, without clinical or analytical improvement. After an exhaustive study, and with more likely diagnoses excluded, cHUS was assumed and treatment with eculizumab was initiated with sustained recovery.

Resumo Introdução: A doença pulmonar obstrutiva crónica (DPOC) é a terceira causa de mortalidade a nível global. O tratamento foca-se na melhoria da qualidade de vida, atraso da progressão da doença e redução das exacerbações. Neste contexto, o benefício da reabilitação respiratória tem vindo a ser verificado. Esta medida não farmacológica pode ser implementada na comunidade, no contexto dos cuidados de saúde primários. Objetivos: Esta revisão sistemática propôs-se a fazer um levantamento da evidência atual sobre o impacto da reabilitação pulmonar na qualidade de vida dos doentes com DPOC, num contexto de cuidados de saúde primários. Métodos: Foram pesquisados estudos randomizados controlados em três bases de dados. Foi incluída a reabilitação pulmonar realizada na comunidade e excluídas intervenções em contexto hospitalar. Foi considerado como resultado primário a qualidade de vida relacionada com a saúde comparando com a terapêutica padrão da DPOC. A extração e triagem de dados foi efetuada por três autores, de forma independente. Avaliou-se o viés pela Cochrane Risk of Bias Tool. Resultados: Quatro estudos corresponderam aos critérios de pesquisa. Três estudos reportaram benefício em pelo menos um dos resultados. A frequência e duração da reabilitação pareceram ter algum impacto nos resultados. A mortalidade foi mais alta nos grupos de controlo. Os estudos incluídos tinham limitações importantes, nomeadamente a incapacidade de realizar intervenções cegas. Conclusões: A reabilitação pulmonar em cuidados de saúde primários melhora a qualidade de vida e capacidade funcional na DPOC. A duração, frequência e modalidade ótimas da intervenção não estão definidas e poderão depender de características individuais. Embora o paradigma não se altere, espera-se que esta revisão fomente o interesse na intervenção.

Abstract Introduction: Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide, and its management involves improving quality of life, delaying progression, and minimizing exacerbations. The benefit of pulmonary rehabilitation in COPD has been documented in the literature. This intervention can be applied to a primary healthcare setting, using community resources. Objectives: This systematic review sought to compile current evidence implying the impact of pulmonary rehabilitation in a primary healthcare setting on the quality of life of patients with COPD. Methods: Three databases were searched for randomized controlled trials. We included community-based pulmonary rehabilitation and excluded interventions in a hospital setting. The primary outcome was health-related quality of life; secondary outcomes were functional exercise capacity and mortality. Data extraction and triage were performed independently by three authors, and bias was evaluated using the Cochrane Risk of Bias Tool. Results: Four studies met the search criteria. Three studies reported benefits in at least one of the outcomes; a fourth reported no differences between groups. Rehabilitation frequency and duration seemed to have some impact on all outcomes. Mortality was higher in the control groups when available. The included studies had important limitations, namely the inability to blind interventions. Conclusions: Pulmonary rehabilitation in a primary health care setting benefits the quality of life and functional exercise capacity in COPD patients. Optimal treatment modality, frequency, and duration are yet to be defined and are perhaps reliant on individual patient attributes. Though unable to add to previous findings, we hope this review fosters interest in this potentially life-changing intervention in a primary healthcare context.

Abstract The objective of this work was to determine the acidity levels to obtain adequate soil chemical attributes for the maximum fruit yield of blackberry trees grown in acidic soils subjected to increasing limestone rates. The BRS Tupy, Brazos, Guarani, and BRS Xavante blackberry cultivars were evaluated on the Typic Hapludox (LVdf) and Rhodic Hapludox (LVd) soils, to which four rates of dolomitic limestone were applied (0, 1.5, 3.0, and 6.0 Mg ha-1). The effect of liming on soil chemical attributes, in a 2×4 factorial arrangement (soils and limestone rates), as well as leaf nutrient content and fruit yield, in a 2×4×4 factorial arrangement (soils, limestone rates, and cultivars), were evaluated. The maximum fruit yield was obtained with 3.3 Mg ha-1 dolomitic limestone. The blackberry cultivars showed a high demand for Ca, Mg, and base saturation and a low tolerance to aluminum in the soils. From 3.3 Mg ha-1 dolomitic limestone, the maximum fruit yield of blackberry trees grown in acidic soils is obtained with pH 5.6, maximum tolerated aluminum saturation of 6%, Ca and Mg concentration of 45.3 mmolc kg-1, and base saturation of 48.3%.

ABSTRACT The Tunicata, despite the relatively low species diversity among the invertebrates, has always received attention not only due to their ecological importance, especially in fouling communities, but also for several species that are studied as models for genetics and the evolution of development, as well as being a prolific source of natural products. In Brazil, research during the last 60 years has considerably increased our knowledge of benthic and planktonic tunicates, resulting from the work of several research teams. In this review, we provide information on the biodiversity of coastal Brazil along with an analysis of geographic distribution, sampling effort, the locations and status of taxonomic collections, and research specialists working on this group.

This is an initial study using infrared (IR) in silico data as a standard database in preliminary method for new synthetic seized drugs. For this purpose, ten of the most common synthetic illicit seized substances on the Brazilian market were compared and computational chemistry was used as a tool for theoretical standard database. Infrared data from standard electronic library, experimental data from seized samples and data simulated by Density Functional Theory (DFT) were evaluated. The feasibility of the method was based on the degree of correlation of evaluated data. The results suggest that the computational methodology can be a viable way to analyze the structures of new synthetic drugs and obtain preliminary infrared profiles. Correlations data indicated a presumptive identification of the analyzed samples and it was also possible to observe a preliminary identification of drugs in five classes. However, it was observed that some synthetic cathinones and phenylethylamines were confused with amphetamines. Therefore, new studies must be developed to optimize the use of these data, because the simulated IR spectra can be advantageous to evaluate the profile of possible substances that may be synthesized in the future. (IR purpose library DFT (DFT profiles classes However amphetamines Therefore future

Biocomposites have gained attention in the packaging industry due to their potential as sustainable alternatives to conventional synthetic materials. In this study, novel cotton incorporated poly(lactic acid)/thermoplastic starch biocomposites were developed for packaging applications using in short shelf life products the extrusion method. Pelletized samples obtained by extrusion were stamped from plates obtained by compression and were characterized through measurement of density, hardness, contact angle and water absorption, as well as Fourier transform infrared spectroscopy (FTIR), thermal analysis and scanning electron microscopy (SEM). No significant changes in the density results were observed. A slight increase in the hardness of formulations in relation to the PLA was associated with the presence of cotton fiber in biocomposites. The FTIR results revealed physical interaction of PLA, TPS and cotton fiber. By DSC analysis, for all formulations the melting exhibited only one peak, suggesting good homogeneity and interaction among the components, as observed by TG/DTG results, and corroborating SEM analysis. The biocomposite PLA/TPS/Cotton 85/10/5 wt.% displayed greater increase in water absorption than both 95/5/0 and 90/5/5 wt.% formulations, which can be attributed to the increase in starch proportion, confirming the contact angle results. The hydrophilic tendency corroborated the biodegradation process in the packaging end-of-life. materials study polylactic poly lactic acid/thermoplastic acidthermoplastic acid /thermoplastic thermoplastic method FTIR, , (FTIR) SEM. .

ABSTRACT Congenital heart disease (CHD) affects eight to ten out of every 1,000 births, resulting in approximately 23,057 new cases in Brazil in 2022. About one in four children with CHD requires surgery or other procedures in the first year of life, and it is expected that approximately 81% of these children with CHD will survive until at least 35 years of age. Professionals choosing to specialize in CHD surgery face numerous challenges, not only related to mastering surgical techniques and the complexity of the diseases but also to the lack of recognition by medical societies as a separate subspecialty. Furthermore, families face difficulties when access to services capable of providing treatment for these children. To address these challenges, it is essential to have specialized hospitals, qualified professionals, updated technologies, sustainable industry, appropriate financing, quality assessment systems, and knowledge generation. The path to excellence involves specialization across all involved parties. As we reflect on the importance of Pediatric Cardiovascular Surgery and Congenital Heart Diseases establishing themselves as a subspecialty of Cardiovascular Surgery, it is essential to look beyond our borders to countries like the United States of America and United Kingdom, where this evolution is already a reality. This autonomy has led to significant advancements in research, education, and patient care outcomes, establishing a care model. By following this path in Brazil, we not only align our practice with the highest international standards but also demonstrate our maturity and the ability to meet the specific needs of patients with CHD and those with acquired childhood heart disease.

ABSTRACT The presence of genetic mutations in HIV poses a significant challenge, potentially leading to antiretroviral resistance and hampering therapeutic development. The Brazilian population has presented variations in the HIV envelope V3 loop gene, especially the GWGR motif. This motif has been linked to reduced transmission potential and slower CD4+ T cell decline. This study aimed to assess clinical outcomes in patients with HIV-1 infected with strains containing the GWGR motif compared with those without it during long-term cART. A cohort of 295 patients with HIV was examined for the GWGR motif presence in the V3 loop. A total of 58 samples showed the GWGR signature, while 237 had other signatures. Multifactorial analyses showed no significant differences in demographic characteristics, CD4+ cell count, AIDS progression, or mortality between GWGR carriers and others. However, the mean interval between the first positive HIV test and the initial AIDS-defining event was more than two times longer for women carrying the GWGR signature (p = 0.0231). We emphasize the positive impact of cART on HIV/AIDS treatment, including viral suppression, CD4+ cell preservation, and immune function maintenance. Although no significant differences were found during cART, residual outcomes reflecting adherence challenges were observed between diagnosis and the first AIDS-defining event. The previously described outcomes, highlighting statistically significant differences between individuals carrying the GPGR motif compared with those with the Brazilian GWGR motif, may be directly linked to the natural progression of infection before advancements in cART. Presently, these physicochemical aspects may no longer hold the same relevance. challenge development V gene CD4 CD decline HIV1 1 HIV- longterm long term 29 5 23 signatures characteristics count others However AIDSdefining defining p 0.0231. 00231 0.0231 . 0 0231 0.0231) HIVAIDS treatment suppression preservation maintenance Presently relevance 2 0023 0.023 023 002 0.02 02 00 0.0 0.

Resumo Antecedentes Dados acerca da prevalência da estenose arterial intracraniana (EAIC) entre os pacientes com acidente vascular isquêmico (AVCi) agudo no Brasil e América Latina são limitados. Objetivo O presente estudo pretendeu investigar a frequência e os preditores da EAIC nos pacientes AVCi ou ataque isquêmico transitório (AIT) em um centro brasileiro utilizando o Doppler transcraniano colorido (duplex transcraniano). Métodos Pacientes consecutivos com AVCi ou AIT, admitidos entre fevereiro e dezembro de 2014 em um centro acadêmico brasileiro especializado em doenças cerebrovasculares, foram avaliados prospectivamente com duplex transcraniano. Os estreitamentos vasculares > 50% foram considerados como EAIC, baseado em critérios ultrassonográficos definidos previamente na literatura. Resultados Foram avaliados 170 pacientes com AVCi ou AIT, dos quais 27 (15,9%) foram excluídos em decorrência da janela óssea transtemporal acústica inadequada. Confirmamos EAIC em 55 pacientes (38,5%). A localização mais comum foi o segmento proximal da artéria cerebral média (28,2%), seguida pelas artérias vertebral (15,4%), cerebral posterior (13,6%), carótida interna terminal (9,1%) e basilar (8,2%). No modelo multivariado, ajustado para os potenciais confundidores, a pressão arterial sistólica aumentada (OR: 1,03; IC 95%: 1,01–1,04; p = 0,008) foi independentemente associada a EAIC. Conclusão Foi identificada EAIC significativa em quase ⅓ dos pacientes admitidos com sintomas de AVCi ou AIT em um serviço acadêmico público de atendimento especializado em doenças cerebrovasculares. O Doppler transcraniano colorido é uma ferramenta acessível e não invasiva que pode ser utilizada com segurança para a investigação da presença de EAIC moderada ou grave, especialmente nos pacientes que não podem ser expostos a exames complementares mais invasivos com uso de contraste intravenoso.

Abstract Background There is limited data available regarding the prevalence of intracranial arterial stenosis (ICAS) among acute ischemic stroke (AIS) patients in Brazil and Latin America. Objective The present study sought to investigate the frequency and predictors of ICAS among patients with AIS or transient ischemic attack (TIA) in a Brazilian center, with transcranial color-coded duplex sonography (TCCS) technique. Methods Consecutive AIS and TIA patients, admitted to an academic public comprehensive stroke center in Brazil from February to December 2014, evaluated by TCCS were prospectively selected. Vascular narrowings > 50% were considered as ICAS, based on ultrasound criteria previously defined in the literature. Results We assessed 170 consecutive patients with AIS or TIA, of whom 27 (15.9%) were excluded due to an inadequate transtemporal acoustic bone window. We confirmed ICAS in 55 patients (38.5%). The most common location was the proximal segment of the middle cerebral artery (28.2%), followed by the vertebral (15.4%), posterior cerebral (13.6%), terminal internal carotid (9.1%) and basilar (8.2%) arteries. On multivariate models adjusting for potential confounders, systolic blood pressure (OR: 1.03, 95%CI: 1.01–1.04; p = 0.008) was independently associated with ICAS. Conclusion We found significant ICAS in approximately ⅓ of patients admitted with symptoms of AIS or TIA in a public tertiary academic stroke center in Brazil. The TCCS is an accessible and noninvasive technique that can be used to investigate the presence of moderate and severe ICAS, especially in patients who cannot be exposed to more invasive exams, such as the use of intravenous contrast agents.
