ABSTRACT Introduction: Urethral stricture is a common, albeit complex, condition that predominantly affects men. The aim of this study was to translate, culturally adapt, and validate the Patient-Reported Outcome Measure questionnaire for patients undergoing urethroplasty (USS-PROM) into Brazilian Portuguese using validated psychometric criteria. Materials and Methods: The process involved translating and culturally adapting the original USS-PROM into Brazilian Portuguese (USS-PROMbr), synthesizing, back-translating, cross-culturally adapting, and analyzing the pre-final version with experts from our committee. This pre-version was administered to 10 patients who had undergone urethroplasty by the Reconstructive Urology team at the Hospital de Clínicas de Porto Alegre for face validation, linguistic, and semantic adjustments, resulting in the final USS-PROMbr version. Subsequently, well-established psychometric criteria, including content validity, internal consistency, and test-retest reproducibility, were assessed after administering the questionnaire to a total of 56 patients, with 50 of them responding to the test and retest. Results: Evaluation of the pre-final version identified 15 questions as clear, and only one question was considered somewhat unclear necessitating modifications based on patient suggestions and subsequent reassessment by the research team. Psychometric criteria demonstrated good content validity, with a content validity index exceeding 0.80 for all questions; good internal consistency, Cronbach's alpha of 0.77, ranging from 0.70 to 0.78 with the exclusion of any item, and item-total correlations ranging from 0.33 to 0.67. The test-retest intraclass correlation coefficient was 0.74 for the lower urinary tract symptoms construct (Q1-Q6). Conclusion: The USS-PROMbr demonstrated acceptable cross-cultural adaptation and psychometric properties, making it a valid and useful tool for evaluating patients undergoing urethroplasty.

ABSTRACT: The aim of this study was to evaluate the vital signs related with different dental treatments, and correlate with demographic data and participants’ anxiety level. This is a prospective clinical study with 60 participants, divided into 3 groups of dental procedures: (1) restorative treatment, (2) extractions and biopsies, and (3) gingival treatment. A level of anxiety questionnaire before dental procedure proposed by Corah’s Dental Anxiety Scale was collected. Respiratory rate, systolic and diastolic pressure, temperature and oxygenation were measured before, during and after the procedures. 31 (51.7 %) women and 29 (48.3 %) men were included, with mean age of 41.75 years old. Most participants (50 %) were classified as very little anxious. Diastolic pressure before the procedure was higher for slightly anxious patients when compar ed with very little anxious patients (p=0.028). Systolic pressure before, during and after the procedure was higher for participan ts above 40 years old (p=0,001). Heart rate (p=0,050) and temperature (p=0,041) was higher before the restorative treatment. Anxiety can promote changes in vital signs in the dental environment. Vital signs, sex, age and level of anxiety do influence the blood pressure at different clinical moments. Dental procedures have association with variations in temperature, heart and respiratory rate.

RESUMEN: El objetivo de este estudio fue evaluar los signos vitales relacionados con diferentes tratamientos dentales y correlacionarlos con datos demográficos y el nivel de ansiedad de los participantes. Este es un estudio clínico prospectivo con 60 participantes, divididos en 3 grupos de procedimientos dentales: (1) tratamiento restaurador, (2) extracciones y biopsias, y (3) tratamiento gingival. Se recogió un cuestionario de nivel de ansiedad antes del procedimiento odontológico propuesto por la Escala de Ansiedad Dental de Corah. Se midieron la frecuencia respiratoria, la presión sistólica y diastólica, la temperatura y la oxigenación antes, durante y después de los procedimientos. Se incluyeron 31 (51,7 %) mujeres y 29 (48,3 %) hombres, con edad media de 41,75 años. La mayoría de los participantes (50 %) fueron clasificados como muy poco ansiosos. La presión diastólica antes del procedimiento fue mayor en los pacientes ligeramente ansiosos en comparación con los pacientes muy poco ansiosos(p=0,028). La presión sistólica antes, durante y después del procedimiento fue mayor para los participantes mayores de 40 años (p=0,001). La frecuencia cardíaca (p=0,050) y la temperatura (p=0,041) fueron mayores antes del tratamiento restaurativo. La ansiedad puede promover cambios en los signos vitales en el entorno dental. Los signos vitales, el sexo, la edad y el nivel de ansiedad sí influyen en la presión arterial en los diferentes momentos clínicos. Los procedimientos dentales tienen asociación con variaciones de temperatura, frecuencia cardíaca y respiratoria.

ABSTRACT Introduction Instruments to manage adverse effects of endocrine therapy with Aromatase inhibitors (AI) may improve adherence and persistence to treatment and Health-Related Quality of Life (HRQL). The 31-item Cervantes Scale (CS-31) is an HRQL questionnaire with particularities of the perimenopausal and postmenopausal period that could be an appropriate instrument to assess HRQL in Breast Cancer (BC) survivors. Objective This study aimed to perform additional validation of the CS-31 for BC survivors undergoing adjuvant endocrine therapy. Methods This prospective study was performed at three time points named T0, T1, and T2: initial, intermediate, and final follow-up period, respectively, totaling 24 months of follow-up. At each time point, the participants completed the CS-31, Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F), and Hospital Anxiety and Depression Scale (HADS). The internal consistency, construct validity, responsiveness analyses, and known-group validity of CS-31 were evaluated. Results This study included 89 postmenopausal women diagnosed with hormone receptor-positive early BC in adjuvant endocrine therapy with AI. The internal consistency was good (Cronbach's alpha = 0.89). Construct validity received a positive rating, with 100% of results consistent with prior hypotheses. A prospective improvement in HRQL was identified for the CS-31 Global Score and FACIT-F Total Score and for most of their domains. Furthermore, women with anxiety and depression by HADS presented worse HRQL by CS-31. Conclusion The authors identified that the CS-31 seems to be appropriate for use in oncology medical routine and may help to monitor adverse effects and HRQL of BC survivors during adjuvant endocrine therapy.

Abstract This study evaluated the nutritional and productive performance of Nellore purebred heifers and crossbred Brangus x Nellore (BGNE) and Braford x Nellore (BFNE) in a feedlot system. Thirty heifers (10 of each genetic group) with an average age of 18 months and an initial body weight of 261 kg were used. The experiment was structured and conducted according to a completely randomized design, with three treatments. Heifers received two diets (60 days each) during the experimental period. The experiment lasted 120 days with four experimental periods. Nellore heifers had a lower intake than crossbred heifers (P <0.05). There were no differences between BGNE and BFNE heifers, which had higher final body weight, average daily gain, feed efficiency, hot carcass weight and carcass length than NE heifers. Crossed heifers presented better fat cover than NE heifers. However, NE heifers had higher carcass dressing Despite presenting lower carcass yields than Nellore heifers, crossed heifers are more efficient and have higher performance and better fat cover on the carcass than purebred Nellore heifers. Crossbreeding synthetic breeds, such as Brangus and Braford breeds, with the Nellore breed is an effective way to increase the productivity and efficiency of feedlot heifers in tropical regions.

ABSTRACT Introduction: The nose has great aesthetic and functional importance, with a high incidence of malignant lesions. There are several techniques for reconstructing the distal third of the nose, but there is no universal indication; will depend on the characteristics of the injury. Surgical options vary between skin grafts and local, regional, and microsurgical flaps. The objective is to present a series of cases of reconstruction of the distal third of the nose using different surgical techniques, discussing the peculiarities and the results obtained. Method: This is a retrospective study carried out at the Hospital do Servidor Público Estadual de São Paulo (HSPE), evaluating a series of eight patients diagnosed with non-melanoma skin cancer located in the distal third of the nose and who underwent reconstruction by the team of Plastic Surgery. Results: Satisfactory results were obtained for all patients undergoing distal nose reconstruction, using total skin graft techniques (n=1) and local flaps (n=7), such as the bilobed, nasolabial, and dorsal nose flap. nose, paramedian frontal, and nasolabial transposition. Conclusion: Reconstruction of defects in the distal third of the nose is challenging and involves great technical variability. A careful assessment of the patient and the injury must be carried out, risks and benefits assessed and the decision shared with the patient.

Abstract Background Patients with epilepsy (PWE) frequently have comorbid psychiatric disorders, the most common of which are depression and anxiety. Attention deficit disorder with hyperactivity (ADHD) is also more frequent among PWE, though that condition has been scarcely studied among the adult PWE population. Objective This study aimed to compare the presence of ADHD symptoms between adult PWE and the general population. Methods This was an observational case-control study. Ninety-five adult PWE from a tertiary center in southern Brazil were compared with 100 healthy controls. All subjects were submitted to three structured scales: 1) the World Health Organization Adult ADHD Self-Report Scale version 1.1 (ASRS); 2) the Hospital Anxiety and Depression Scale (HADS); and 3) the Adverse Events Profile (AEP). Dichotomic variables were analyzed through chi-square test and Fisher's exact test, as appropriate, and non-parametric variables were analyzed through the Mann-Whitney U test. Results Medians and interquartile ranges (IR) were: 1) ASRS: 26.00 (IR: 18 to 38) among PWE versus 17.00 (IR: 11 to 24) among controls, p< 0.001; 2) HADS: 14.00 (IR: 8 to 21) among PWE versus 11.00 (IR: 8 to 16) among controls, p= 0.007; 3) AEP: 3800 (IR: 31 to 49) among PWE versus 33.00 (IR: 23 to 43) among controls, p= 0.001. Conclusion PWE showed a higher burden of symptoms of ADHD, depression, and anxiety when compared with controls, which replicates in the Brazilian population the findings of current literature that point toward a higher prevalence of such disorders among PWE.

Resumo Antecedentes Pacientes com epilepsia (PCE) frequentemente apresentam comorbidades psiquiátricas, principalmente depressão e ansiedade. O transtorno do déficit de atenção e hiperatividade (TDAH) também é mais frequente nos PCE, porém foi pouco estudado na população adulta de PCE. Objetivo Comparar a presença de sintomas de TDAH entre PCE adultos e a população geral. Métodos Noventa e cinco PCE adultos de um centro terciário no Sul do Brasil foram comparados a 100 controles saudáveis. Todos os sujeitos foram submetidos a três escalas estruturadas: 1) a Escala Autorrelatada de TDAH em Adultos da Organização Mundial da Saúde, versão 1.1 (ASRS); 2) a Escala Hospitalar de Ansiedade e Depressão (HADS); e 3) o Perfil de Eventos Adversos (AEP). Variáveis dicotômicas foram analisadas através dos testes chi-quadrado e exato de Fisher, conforme apropriado, e as variáveis não paramétricas foram analisadas através do teste U de Mann-Whitney. Resultados As medianas e os intervalos interquartis (IIQ) foram: 1) ASRS: 26.00 (IIQ: 18 a 38) em PCE versus 17.00 (IIQ: 11 a 24) nos controles, p< 0,001; 2) HADS: 14.00 (IIQ: 8 a 21) em PCE versus 11.00 (IIQ: 8 a 16) nos controles, p= 0,007; 3) AEP: 38.00 (IIQ: 31 a 49) em PCE versus 33.00 (IIQ: 23 a 43) nos controles, p= 0,001. Conclusão PCE apresentaram uma maior carga de sintomas de TDAH, depressão e ansiedade quando comparados aos controles, o que replica na população brasileira os achados da literatura atual, que apontam para uma maior prevalência de tais transtornos entre PCE.

Abstract Background: Transthyretin amyloidosis (ATTR) is an infiltrative disease caused by abnormal protein deposition mainly in the heart and peripheral nervous system. When it affects the heart, the disease presents as restrictive cardiomyopathy; when it affects the peripheral and autonomic nervous system, it manifests as polyneuropathy, and is called familial amyloid polyneuropathy (FAP). There are two ATTR subtypes: wild-type ATTR, where there is no mutation, and mutant ATTR (ATTRm), which is characterized by a mutation in the gene encoding the transthyretin protein (TTR). In both subtypes, cardiac involvement is the major marker of poor prognosis. Objectives: To assess the prevalence of subclinical cardiac involvement in a sample of patients with TTR gene mutation by using pyrophosphate scintigraphy and strain echocardiography; to compare scintigraphy and strain findings; to evaluate the association between neurological manifestations (FAP) and subclinical cardiac involvement; and to analyze whether there is an association between any specific mutation and cardiac involvement. Methods: This is a cross-sectional study with carriers of the TTR gene mutation, without cardiovascular symptoms or changes in electrocardiographic or conventional echocardiographic parameters. All patients underwent pyrophosphate scintigraphy and strain echocardiography. Subclinical cardiac involvement was defined as a Perugini score ≥ 2, heart-to-contralateral lung (H/CL) ratio ≥ 1.5 at 1 h, H/CL ≥1.3 at 3 h, or global longitudinal strain (GLS) ≤ −17%. Descriptive and analytical analyses were performed and Fisher's exact test and Mann–Whitney test were applied. A value of p < 0.05 was considered significant. Results: The 23 patients evaluated had a median age of 51 years (IQR 37–57 years), 15 (65.2%) were female, 12 (52.2%) were Pardo, nine (39.1%) had systemic arterial hypertension, and nine (39.1%) had a previous diagnosis of FAP. Of the nine patients with FAP, 8 (34.8%) were on tafamidis. The associated mutations were Val142IIe, Val50Met, and IIe127Val. The median GLS in the sample was −19% (−16% to −20%). Of the 23 patients, nine (39.1%; 95% CI = 29–49%) met criteria for cardiac involvement, six (26%) by the GLS-based criteria only. There was no association between having FAP and being an asymptomatic carrier, as assessed by strain echocardiography and pyrophosphate scintigraphy (p = 0.19). The prevalence of systemic arterial hypertension, diabetes mellitus, dyslipidemia, smoking, and reduced GLS did not differ between groups. Septal e’ wave velocity was the only variable that significantly differed between individuals with and without reduced GLS, with an area under the ROC curve of 0.80 (95% CI = 0.61–0.98, p = 0.027). The best diagnostic accuracy was achieved with a septal e’ velocity ≤ 8.5 cm/s. There was no association between mutation type and preclinical cardiac involvement, nor between tafamidis use and lower degree of cardiac involvement (37.5% versus 40.0%, p = 0.90). Conclusion: Subclinical cardiac involvement was common in a sample of TTR mutation carriers without cardiac involvement. Reduced left ventricular GLS was the most frequent finding. There was no association between the presence of amyloid polyneuropathy and subclinical cardiac involvement. Type of mutation was not associated with early cardiac involvement. In this sample, the use of tafamidis 20 mg/day was not associated with a lower prevalence of subclinical cardiac involvement.

Resumo Fundamento: A amiloidose por transtirretina (ATTR) é uma doença infiltrativa causada pela deposição anormal de proteína principalmente no coração e no sistema nervoso periférico. Quando acomete o coração, a doença manifesta-se como uma cardiomiopatia restritiva e, quando afeta o sistema nervoso periférico e autônomo, apresenta-se como uma polineuropatia, podendo ser chamada de Polineuropatia Amiloidótica Familiar (PAF). Existem dois subtipos de ATTR, a ATTR selvagem, em que não há variantes genéticas, e a ATTR hereditária, caracterizada por uma variante no gene que codifica a proteína transtirretina (T\TR). Em ambos os subtipos, o envolvimento cardíaco é o principal marcador prognóstico. Objetivos: Avaliar a prevalência do envolvimento cardíaco subclínico em uma amostra de pacientes com variantes genéticas no gene TTR usando a cintilografia com pirofosfato e o ecocardiograma com strain; comparar os achados cintilográficos e as medidas de strain; avaliar a associação entre PAF e o envolvimento subclínico; e analisar se existe uma associação entre uma variante genética específica e o envolvimento cardíaco. Métodos: Estudo transversal com carreadores de variantes no gene TTR sem sintomas cardiovasculares e sem alterações nos parâmetros da eletrocardiografia ou do ecocardiograma convencional. Todos os pacientes foram submetidos à cintilografia com pirofosfato e à ecocardiografia com análise de strain. O envolvimento cardíaco subclínico, definido como um escore de Perugini ≥ 2, razão Coração (C)/ Hemitórax Contralateral (CL) ≥ 1,5 em uma hora, C/CL ≥ 1,3 na terceira hora, ou um strain longitudinal global (SGL) ≤ −17%. Realizadas análises descritiva e analítica, e aplicados o teste exato de Fisher e o teste de Mann-Whitney. Um valor de p<0,05 foi considerado significativo. Resultados: Os 23 pacientes avaliados apresentavam uma idade mediana de 51 (37-57) anos, 15 (65,2%) eram do sexo feminino, 12 (52,2%) eram pardos, nove (39,1%) apresentavam hipertensão arterial sistêmica, e nove (39,1%) tinham um diagnóstico prévio de PAF. Dos nove pacientes com PAF, oito (34,8%) usavam tafamidis. As variantes genéticas identificadas foram Val142IIe, Val50Met e IIe127Val. O valor mediano do SGL foi −19% (-16% – −20%). Dos 23 pacientes, nove (39,1%; 95% CI = 29–49%) preencheram os critérios de envolvimento cardíaco, seis (26%) somente pelo critério do SGL. Não houve associação entre PAF e um carreador assintomático avaliado por ecocardiograma com análise de strain e pela cintilografia com pirofostato (p=0,19). A prevalência de hipertensão arterial sistêmica, diabetes mellitus, dislipidemia, tabagismo e SGL reduzido não foi diferente entre os grupos. A velocidade da onda e’ septal foi a única variável que apresentou diferença significativa entre os indivíduos com e sem SGL reduzido, com uma área sob a curva ROC de 0,80 (IC95% = 0,61–0,98, p = 0,027). A melhor acurácia diagnóstica foi alcançada com uma velocidade e’ septal ≤ 8,5 cm/s. Não houve associação entre o tipo de variante genética e o envolvimento cardíaco pré-clínico, nem entre o uso de tafamidis e este mesmo envolvimento (37,5% versus 40,0%, p = 0,90). Conclusão: O envolvimento cardíaco subclínico foi frequente em uma amostra de carreadores da variante genética do gene TTR. Um valor do SGL reduzido foi o achado mais comum. Não houve associação entre a presença de polineuropatia amiloidótica e o envolvimento subclínico. O tipo de variante genética não foi associado com envolvimento cardíaco precoce. Nesta amostra, o uso de tafamidis (20mg/dia) não foi associado com uma menor prevalência de envolvimento cardíaco subclínico. Fundamento (ATTR manifestase manifesta autônomo apresentase apresenta .

ABSTRACT Background: Driving pressure has been suggested to be the main driver of ventilator-induced lung injury and mortality in observational studies of acute respiratory distress syndrome. Whether a driving pressure-limiting strategy can improve clinical outcomes is unclear. Objective: To describe the protocol and statistical analysis plan that will be used to test whether a driving pressure-limiting strategy including positive end-expiratory pressure titration according to the best respiratory compliance and reduction in tidal volume is superior to a standard strategy involving the use of the ARDSNet low-positive end-expiratory pressure table in terms of increasing the number of ventilator-free days in patients with acute respiratory distress syndrome due to community-acquired pneumonia. Methods: The ventilator STrAtegy for coMmunIty acquired pNeumoniA (STAMINA) study is a randomized, multicenter, open-label trial that compares a driving pressure-limiting strategy to the ARDSnet low-positive end-expiratory pressure table in patients with moderate-to-severe acute respiratory distress syndrome due to community-acquired pneumonia admitted to intensive care units. We expect to recruit 500 patients from 20 Brazilian and 2 Colombian intensive care units. They will be randomized to a driving pressure-limiting strategy group or to a standard strategy using the ARDSNet low-positive end-expiratory pressure table. In the driving pressure-limiting strategy group, positive end-expiratory pressure will be titrated according to the best respiratory system compliance. Outcomes: The primary outcome is the number of ventilator-free days within 28 days. The secondary outcomes are in-hospital and intensive care unit mortality and the need for rescue therapies such as extracorporeal life support, recruitment maneuvers and inhaled nitric oxide. Conclusion: STAMINA is designed to provide evidence on whether a driving pressure-limiting strategy is superior to the ARDSNet low-positive end-expiratory pressure table strategy for increasing the number of ventilator-free days within 28 days in patients with moderate-to-severe acute respiratory distress syndrome. Here, we describe the rationale, design and status of the trial.

RESUMO Contexto: Em estudos observacionais sobre a síndrome do desconforto respiratório agudo, sugeriu-se que a driving pressure é o principal fator de lesão pulmonar induzida por ventilador e de mortalidade. Não está claro se uma estratégia de limitação da driving pressure pode melhorar os desfechos clínicos. Objetivo: Descrever o protocolo e o plano de análise estatística que serão usados para testar se uma estratégia de limitação da driving pressure envolvendo a titulação da pressão positiva expiratória final de acordo com a melhor complacência respiratória e a redução do volume corrente é superior a uma estratégia padrão envolvendo o uso da tabela de pressão positiva expiratória final baixa do protocolo ARDSNet, em termos de aumento do número de dias sem ventilador em pacientes com síndrome do desconforto respiratório agudo devido à pneumonia adquirida na comunidade. Métodos: O estudo STAMINA (ventilator STrAtegy for coMmunIty acquired pNeumoniA) é randomizado, multicêntrico e aberto e compara uma estratégia de limitação da driving pressure com a tabela de pressão positiva expiratória final baixa do protocolo ARDSnet em pacientes com síndrome do desconforto respiratório agudo moderada a grave devido à pneumonia adquirida na comunidade internados em unidades de terapia intensiva. Esperamos recrutar 500 pacientes de 20 unidades de terapia intensiva brasileiras e duas colombianas. Eles serão randomizados para um grupo da estratégia de limitação da driving pressure ou para um grupo de estratégia padrão usando a tabela de pressão positiva expiratória final baixa do protocolo ARDSnet. No grupo da estratégia de limitação da driving pressure, a pressão positiva expiratória final será titulada de acordo com a melhor complacência do sistema respiratório. Desfechos: O desfecho primário é o número de dias sem ventilador em 28 dias. Os desfechos secundários são a mortalidade hospitalar e na unidade de terapia intensiva e a necessidade de terapias de resgate, como suporte de vida extracorpóreo, manobras de recrutamento e óxido nítrico inalado. Conclusão: O STAMINA foi projetado para fornecer evidências sobre se uma estratégia de limitação da driving pressure é superior à estratégia da tabela de pressão positiva expiratória final baixa do protocolo ARDSnet para aumentar o número de dias sem ventilador em 28 dias em pacientes com síndrome do desconforto respiratório agudo moderada a grave. Aqui, descrevemos a justificativa, o desenho e o status do estudo.

Abstract This study assessed the intratubular antibacterial ability of different activated irrigations after chemical mechanical preparation. Seventy-two palatal root canals of upper molars were infected with Enterococcus faecalis for 4 weeks, and then initial bacterial collection from the main root canal was performed. The root canals were prepared by using a WaveOne Gold large (45/.05) and distributed into 6 groups according to the activation of the final irrigation: ultrasonic activation (UA), XP-Endo Finisher (25/.00), XP Clean (25/.02), EasyClean (25/.04) in reciprocating motion and continuous rotary motion (ECRot), and conventional irrigation. After final irrigation, another bacterial collection from the main root canal was performed, and the root was sectioned transversely in three-thirds and stained for analysis by confocal laser microscopy. Intratubular bacteria were collected through dentin powder and plated for bacterial viability analysis. Intergroup and intragroup comparisons were performed by using analysis of variance and repeated measures analysis of variance, respectively, both at 5% significance. ECRot had higher antibacterial ability than UA (p<0.05), and both were superior to the other groups (p<0.05) in both methodologies. It can be concluded that activation of final irrigation enhances the disinfection of the root canal system, and activators have different efficacies preparation Seventytwo Seventy two weeks 45/.05 4505 45 05 (45/.05 UA, , (UA) XPEndo Endo 25/.00, 2500 25/.00 25 00 (25/.00) 25/.02, 2502 25/.02 02 (25/.02) 25/.04 2504 04 (25/.04 ECRot, (ECRot) threethirds three thirds microscopy respectively 5 significance p<0.05, p005 p p<0.05 0 (p<0.05 methodologies system 45/.0 450 (45/.0 (UA 250 25/.0 2 (25/.00 (25/.02 (25/.0 (ECRot p00 p<0.0 (p<0.0 45/.

Resumo Este estudo avaliou a capacidade antibacteriana intratubular de diferentes irrigações ativadas após o preparo químico-mecânico. Setenta e dois canais palatinos de molares superiores foram contaminados com Enterococcus faecalis por 4 semanas, e então a coleta bacteriana inicial do canal principal foi realizada. Os canais foram preparados com WaveOne Gold large (45/.05) e distribuídos em 6 grupos de acordo com a ativação da irrigação final: ativação ultrassônica (UA), XP-Endo Finisher (25/.00), XP Clean (25/.02), EasyClean (25/.04) em movimento reciprocante e em movimento rotatório contínuo (ECRot) e irrigação convencional. Após a irrigação final, outra coleta bacteriana do canal principal foi realizada, e a raiz foi seccionada transversalmente em três terços e corada para análise por microscopia laser confocal. Bactérias intra tubulares foram coletadas através de pó de dentina e cultivadas para análise de viabilidade bacteriana. As comparações entre grupos e intragrupos foram realizadas usando análise de variância e análise de variância de medidas repetidas, respectivamente, ambas com 5% de significância. ECRot apresentou maior capacidade antibacteriana que UA (p<0,05), e ambos foram superiores aos demais grupos (p<0,05) em ambas as metodologias. Pode-se concluir que a ativação da irrigação final melhora a desinfecção do sistema de canais radiculares, e os ativadores têm eficácias diferentes. químicomecânico. químicomecânico químico mecânico. mecânico químico-mecânico semanas realizada 45/.05 4505 45 05 (45/.05 UA, , (UA) XPEndo Endo 25/.00, 2500 25/.00 25 00 (25/.00) 25/.02, 2502 25/.02 02 (25/.02) 25/.04 2504 04 (25/.04 (ECRot convencional confocal repetidas respectivamente 5 significância p<0,05, p005 p p<0,05 0 (p<0,05 metodologias Podese Pode se radiculares 45/.0 450 (45/.0 (UA 250 25/.0 2 (25/.00 (25/.02 (25/.0 p00 p<0,0 (p<0,0 45/.

Abstract Increasing habitat modification and species loss demand consistent efforts to describe and understand biodiversity patterns. The BIOTA/FAPESP Program was created in this context and it has been a successful initiative to promote studies on biodiversity and conservation in Brazil. The BIOTA/Araçá is an interdisciplinary project that provided a detailed evaluation of the biodiversity of Araçá Bay, a coastal seascape located on the North coast of the state of São Paulo, Southeast Brazil. The bay encompasses multiple habitats, such as beaches, mangroves, rocky shores, and a tidal flat, and provides important ecosystem services. Unfortunately, the bay is the subject of complex social-environmental conflicts that oppose economic, social, and environmental demands (i.e., the expansion of neighboring harbor activities vs. small-scale artisanal fisheries and protection of biodiversity). The present study presents a survey of the benthic species occurring in the different habitats of Araçá Bay, including data obtained during the BIOTA/Araçá project and previous assessments of the area. The benthic species play an important role in marine environments and studying the diversity of these organisms that live associated with the bottom is indispensable for comprehending the environment’s functioning. The macrofauna, meiofauna, and microorganisms associated with soft and hard bottom were listed, and additional information, such as the habitat and geographical distribution, were provided for each species. The checklist includes 826 species, almost 70% recorded during the BIOTA/Araçá project. The most speciose taxa were the annelids (225 spp.), mollusks (194 spp.), and crustaceans (177 spp.). Seven benthic species are endemic to Araçá Bay, 14 are considered threatened, and seven are economically exploited. Furthermore, the bay is the type locality of many taxa, and 11 new benthic species were described based on specimens sampled during the project. This project shows the importance of Araçá Bay as a unique biologically rich environment and highlights the need for conservation efforts in light of the current threats. patterns BIOTAFAPESP BIOTA FAPESP Brazil BIOTAAraçá Paulo beaches mangroves shores flat services Unfortunately socialenvironmental social economic i.e., ie i e (i.e. vs smallscale small scale biodiversity. . biodiversity) area s functioning macrofauna meiofauna listed information distribution 82 70 225 (22 spp., spp spp. , spp.) 194 (19 177 (17 spp.. 1 threatened exploited Furthermore threats i.e. (i.e 8 7 22 (2 19 (1 17 i.e 2 (

Resumo O aumento da modificação dos habitats e da perda de espécies demanda esforços consistentes para descrever e compreender os padrões de biodiversidade. O programa BIOTA/FAPESP foi criado nesse contexto e é uma iniciativa de sucesso para promover estudos em biodiversidade e conservação no Brasil. O BIOTA/Araçá é um projeto interdisciplinar que promoveu uma avaliação detalhada da biodiversidade da Baía do Araçá, um ecossistema costeiro localizado ao Norte do estado de São Paulo, Sudeste do Brasil. A baía engloba múltiplos habitats, tais como praias, manguezais, costões rochosos, e uma planície de maré, e também fornece importantes serviços ecossistêmicos. Infelizmente, a baía está sujeita à conflitos sócio-ambientais complexos que contrastam demandas econômicas, sociais e ambientais (i.e. a expansão das atividades do porto vizinho vs. a pesca artesanal de pequena escala e a proteção da biodiversidade). O presente estudo apresenta um levantamento das espécies bentônicas que ocorrem nos diferentes habitats da Baía do Araçá, incluindo dados obtidos durante o projeto BIOTA/Araçá e de investigações realizadas anteriormente na área. As espécies bentônicas desempenham um papel importante no ambiente marinho, e estudar a diversidade desses organismos que vivem associados ao fundo é indispensável para compreender o funcionamento do meio ambiente. A macrofauna, meiofauna, e microorganismos associados aos fundos consolidado e inconsolidado foram listados, e informações adicionais foram fornecidas para cada espécie, tais como a distribuição geográfica e nos habitats. O checklist inclui 826 espécies, quase 70% registradas durante o projeto BIOTA/Araçá. Os taxa mais especiosos foram os anelídeos (225 spp.), moluscos (194 spp.), e crustáceos (177 spp.). Entre as espécies bentônicas listadas, sete são endêmicas da Baía do Araçá, 14 são consideradas ameaçadas de extinção, e sete são exploradas economicamente. A baía é a localidade tipo de vários taxa, e 11 novas espécies bentônicas foram descritas com base em espécimes amostrados durante o projeto. Este projeto mostra a importância da Baía do Araçá como um ambiente de riqueza biológica única e demonstra a necessidade de esforços para a sua conservação considerando as atuais ameaças.

Abstract New materials and technologies used in construction constantly need improvements, whereby the leveraging of new raw materials for the manufacture of products already in use, such as paving, is required. Thus, this study aimed to determine the mechanical and thermal behavior of pavers containing waste glass and São Tomé stone waste to verify their potential application as cold diffraction. Thereafter, they were comminuted and added to the mixtures for making the pavers having glass waste and São Tomé stone in the range of 0-30% by weight. Mechanical compressive strength and thermal heat absorption tests were performed. Results showed that the replacement of fine aggregates with waste glass and São Tomé stone waste in pavers reached a mechanical resistance of approximately 85% and 73% of that of the reference paver, respectively. The results show that reducing the waste content of pavers can increase the mechanical strength to reach the NBR 9781/87 values. However, pavers with lower mechanical strength can be used in paving pedestrian sidewalks, where the loads are low. Pavers with 30% glass waste achieved a 5.5% reduction in the maximum temperature, which could contribute to the reduction of urban heat islands. improvements use required Thus diffraction Thereafter 030% 030 0 30 0-30 weight performed 85 73 paver respectively 978187 9781 87 9781/8 values However sidewalks low 55 5 5.5 temperature islands 03 3 0-3 8 7 97818 978 9781/ 5. 0- 97 9

ABSTRACT Hepatic injuries in COVID-19 are not yet fully understood and indirect pathways (without viral replication in the liver) have been associated with the activation of vascular mechanisms of liver injury in humans infected with SARS-CoV-2. Golden Syrian hamsters are an effective model for experimental reproduction of moderate and self-limiting lung disease during SARS-CoV-2 infection. As observed in humans, this experimental model reproduces lesions of bronchointerstitial pneumonia and pulmonary vascular lesions, including endotheliitis (attachment of lymphoid cells to the luminal surface of endothelium). Extrapulmonary vascular lesions are well documented in COVID-19, but such extrapulmonary vascular lesions have not yet been described in the Golden Syrian hamster model of SARS-CoV-2 infection. The study aimed to evaluate microscopic liver lesions in Golden Syrian hamsters experimentally infected with SARS-CoV-2. In total, 38 conventional Golden Syrian hamsters, divided into infected group (n=24) and mock-infected group (n=14), were euthanized at 2-, 3-, 4-, 5-, 7-, 14-, and 15-days post infection with SARS-CoV-2. Liver fragments were evaluated by histopathology and immunohistochemical detection of SARS-CoV-2 Spike S2 antigens. The frequencies of portal vein endotheliitis, lobular activity, hepatocellular degeneration, and lobular vascular changes were higher among SARS-CoV-2-infected animals. Spike S2 antigen was not detected in liver. The main results indicate that SARS-CoV-2 infection exacerbated vascular and inflammatory lesions in the liver of hamsters with pre-existing hepatitis of unknown origin. A potential application of this animal model in studies of the pathogenesis and evolution of liver lesions associated with SARS-CoV-2 infection still needs further evaluation.
