Abstract Background Cardiovascular complications of COVID-19 are important aspects of the disease’s pathogenesis and prognosis. Evidence on the prognostic role of troponin and myocardial injury in Latin American hospitalized COVID-19 patients is still scarce. Objectives To evaluate myocardial injury as independent predictor of in-hospital mortality and invasive mechanical ventilation support in hospitalized patients, from the Brazilian COVID-19 Registry. Methods This cohort study is a substudy of the Brazilian COVID-19 Registry, conducted in 31 Brazilian hospitals of 17 cities, March-September 2020. Primary outcomes included in-hospital mortality and invasive mechanical ventilation support. Models for the primary outcomes were estimated by Poisson regression with robust variance, with statistical significance of p<0.05. Results Of 2,925 patients (median age of 60 years [48-71], 57.1% men), 27.3% presented myocardial injury. The proportion of patients with comorbidities was higher among patients with cardiac injury (median 2 [1-2] vs. 1 [0-2]). Patients with myocardial injury had higher median levels of brain natriuretic peptide, lactate dehydrogenase, creatine phosphokinase, N-terminal pro-brain natriuretic peptide, and C-reactive protein than patients without myocardial injury. As independent predictors, C-reactive protein and platelet counts were related to the risk of death, and neutrophils and platelet counts were related to the risk of invasive mechanical ventilation support. Patients with high troponin levels presented a higher risk of death (RR 2.03, 95% CI 1.60-2.58) and invasive mechanical ventilation support (RR 1.87, 95% CI 1.57-2.23), when compared to those with normal troponin levels. Conclusion Cardiac injury was an independent predictor of in-hospital mortality and the need for invasive mechanical ventilation support in hospitalized COVID-19 patients.

Resumo Fundamento As complicações cardiovasculares da COVID-19 são aspectos importantes da patogênese e do prognóstico da doença. Evidências do papel prognóstico da troponina e da lesão miocárdica em pacientes hospitalizados com COVID-19 na América Latina são ainda escassos. Objetivos Avaliar a lesão miocárdica como preditor independente de mortalidade hospitalar e suporte ventilatório mecânico em pacientes hospitalizados, do registro brasileiro de COVID-19. Métodos Este estudo coorte é um subestudo do registro brasileiro de COVID-19, conduzido em 31 hospitais brasileiros de 17 cidades, de março a setembro de 2020. Os desfechos primários incluíram mortalidade hospitalar e suporte ventilatório mecânico invasivo. Os modelos para os desfechos primários foram estimados por regressão de Poisson com variância robusta, com significância estatística de p<0,05. Resultados Dos 2925 pacientes [idade mediana de 60 anos (48-71), 57,1%], 27,3% apresentaram lesão miocárdica. A proporção de pacientes com comorbidades foi maior nos pacientes com lesão miocárdica [mediana 2 (1-2) vs. 1 (0-20)]. Os pacientes com lesão miocárdica apresentaram maiores valores medianos de peptídeo natriurético cerebral, lactato desidrogenase, creatina fosfoquinase, N-terminal do pró-peptídeo natriurético tipo B e proteína C reativa em comparação a pacientes sem lesão miocárdica. Como fatores independentes, proteína C reativa e contagem de plaquetas foram relacionados com o risco de morte, e neutrófilos e contagem de plaquetas foram relacionados ao risco de suporte ventilatório mecânico invasivo. Os pacientes com níveis elevados de troponina apresentaram um maior risco de morte (RR 2,03, IC95% 1,60-2,58) e suporte ventilatório mecânico (RR 1,87;IC95% 1,57-2,23), em comparação àqueles com níveis de troponina normais. Conclusão Lesão cardíaca foi um preditor independente de mortalidade hospitalar e necessidade de suporte ventilatório mecânico em pacientes hospitalizados com COVID-19.

Abstract The rising popularity of various types of wood panels and the advances in manufacturing technology have increased the uses of wood. The bonding of fibers and particles to form panels, however, involves impregnation with resins, such as phenolic adhesives, which delivery desirable quality to the panels due to their insolubility in water, resistance against heat among others, but are also recognized as carcinogenic to humans (IARC, 2004). This study involved measuring the levels of formaldehyde, remaining in wood panels after use and disposal. It was initially evaluated new panels and then examined degraded ones. The results demonstrated significant volatilization of formaldehyde during the degradation process of the panels, with losses of 74.83% for MDF and 85.71% for medium density particleboards (MDP). The results demonstrated significant volatilization of formaldehyde during the degradation process of the panels, with losses of 74.83% for MDF and 85.71% for medium density particleboards (MDP).

Abstract Objective To evaluate clinical characteristics and outcomes of COVID-19 patients infected with HIV, and to compare with a paired sample without HIV infection. Methods This is a substudy of a Brazilian multicentric cohort that comprised two periods (2020 and 2021). Data was obtained through the retrospective review of medical records. Primary outcomes were admission to the intensive care unit, invasive mechanical ventilation, and death. Patients with HIV and controls were matched for age, sex, number of comorbidities, and hospital of origin using the technique of propensity score matching (up to 4:1). They were compared using the Chi-Square or Fisher's Exact tests for categorical variables and the Wilcoxon for numerical variables. Results Throughout the study, 17,101 COVID-19 patients were hospitalized, and 130 (0.76%) of those were infected with HIV. The median age was 54 (IQR: 43.0;64.0) years in 2020 and 53 (IQR: 46.0;63.5) years in 2021, with a predominance of females in both periods. People Living with HIV (PLHIV) and their controls showed similar prevalence for admission to the ICU and invasive mechanical ventilation requirement in the two periods, with no significant differences. In 2020, in-hospital mortality was higher in the PLHIV compared to the controls (27.9% vs. 17.7%; p = 0.049), but there was no difference in mortality between groups in 2021 (25.0% vs. 25.1%; p > 0.999). Conclusions Our results reiterate that PLHIV were at higher risk of COVID-19 mortality in the early stages of the pandemic, however, this finding did not sustain in 2021, when the mortality rate is similar to the control group.

Abstract Background Despite no evidence showing benefits of hydroxychloroquine and chloroquine with or without azithromycin for COVID-19 treatment, these medications have been largely prescribed in Brazil. Objectives To assess outcomes, including in-hospital mortality, electrocardiographic abnormalities, hospital length-of-stay, admission to the intensive care unit, and need for dialysis and mechanical ventilation, in hospitalized COVID-19 patients who received chloroquine or hydroxychloroquine, and to compare outcomes between those patients and their matched controls. Methods A retrospective multicenter cohort study that included consecutive laboratory-confirmed COVID-19 patients from 37 Brazilian hospitals from March to September 2020. Propensity score was used to select matching controls by age, sex, cardiovascular comorbidities, and in-hospital use of corticosteroid. A p-value <0.05 was considered statistically significant. Results From 7,850 COVID-19 patients, 673 (8.6%) received hydroxychloroquine and 67 (0.9%) chloroquine. The median age in the study group was 60 years (46 - 71) and 59.1% were women. During hospitalization, 3.2% of patients presented side effects and 2.2% required therapy discontinuation. Electrocardiographic abnormalities were more prevalent in the chloroquine/hydroxychloroquine group (13.2% vs. 8.2%, p=0.01), and the long corrected QT interval was the main difference (3.6% vs. 0.4%, p<0.001). The median hospital length of stay was longer in the HCQ/CQ + AZT group than in controls (9.0 [5.0, 18.0] vs. 8.0 [4.0, 14.0] days). There was no statistical differences between groups in intensive care unit admission (35.1% vs. 32.0%; p=0.282), invasive mechanical ventilation support (27.0% vs. 22.3%; p=0.074) or mortality (18.9% vs. 18.0%; p=0.682). Conclusion COVID-19 patients treated with chloroquine or hydroxychloroquine had a longer hospital length of stay, when compared to matched controls. Intensive care unit admission, invasive mechanical ventilation, dialysis and in-hospital mortality were similar.

Resumo Fundamento Apesar da ausência de evidência mostrando benefícios da hidroxicloroquina e da cloroquina combinadas ou não à azitromicina no tratamento da covid-19, esses medicamentos têm sido amplamente prescritos no Brasil. Objetivos Avaliar desfechos, incluindo moralidade hospitalar, alterações eletrocardiográficas, tempo de internação, admissão na unidade de terapia intensiva, e necessidade de diálise e de ventilação mecânica em pacientes hospitalizados com covid-19 que receberam cloroquina ou hidroxicloroquina, e comparar os desfechos entre aqueles pacientes e seus controles pareados. Métodos Estudo multicêntrico retrospectivo do tipo coorte que incluiu pacientes com diagnóstico laboratorial de covid-19 de 37 hospitais no Brasil de março a setembro de 2020. Escore de propensão foi usado para selecionar controles pareados quanto a idade, sexo, comorbidades cardiovasculares, e uso de corticosteroides durante a internação. Um valor de p<0,05 foi considerado estatisticamente significativo. Resultados Dos 7850 pacientes com covid-19, 673 (8,6%) receberam hidroxicloroquina e 67 (0,9%) cloroquina. A idade mediana no grupo de estudo foi 60 (46-71) anos e 59,1% eram mulheres. Durante a internação, 3,2% dos pacientes apresentaram efeitos adversos e 2,2% necessitaram de interromper o tratamento. Alterações eletrocardiográficas foram mais prevalentes no grupo hidroxicloroquina/cloroquina (13,2% vs. 8,2%, p=0,01), e o prolongamento do intervalo QT corrigido foi a principal diferença (3,6% vs. 0,4%, p<0,001). O tempo mediano de internação hospitalar foi maior no grupo usando CQ/HCQ em relação aos controles (9,0 [5,0-18,0] vs. 8,0 [4,0-14,0] dias). Não houve diferenças estatisticamente significativas entre os grupos quanto a admissão na unidade de terapia intensiva (35,1% vs. 32,0%; p=0,282), ventilação mecânica invasiva (27,0% vs. 22,3%; p=0,074) ou mortalidade (18,9% vs. 18,0%; p=0,682). Conclusão Pacientes com covid-19 tratados com cloroquina ou hidroxicloroquina apresentaram maior tempo de internação hospitalar, em comparação aos controles. Não houve diferença em relação a admissão em unidade de terapia intensiva, necessidade de ventilação mecânica e mortalidade hospitalar.

Resumo Este trabalho teve como objetivo caracterizar a lignina na parede celular de Euterpe oleracea Mart. Foram adquiridas amostras de duas regiões da base da palmeira: região externa e região interna (OR e IR, respectivamente). A extração com solventes orgânicos e o tratamento com NaOH 1% foram realizados. O conteúdo de holocelulose, α-celulose e lignina foi quantificado, esta última também isolada pelo método de Björkman para a caracterização estrutural utilizando RMN de 1H e 13C no estado líquido, assim como análises espectroscópicas (FTIR) e cromatográficas. O caule extraído apresentou 10,33% (OR) e 15,66% (IR) de lignina. Após tratamento com NaOH 1%, observou-se uma redução desses valores, e foi possível confirmar esse resultado também através da diminuição nas intensidades dos sinais referentes aos grupos funcionais ligados à lignina e hemicelulose. As análises espectroscópicas e cromatográficas revelaram lignina do tipo GS incorporada com ácido p-hidroxibenzoico e protocatecuico em ambas as amostras. Também foram observadas as principais unidades estruturais presentes na lignina como ligação β-O-4, β-O-4’ ϒ-acetiladas, spiro-dienona, unidade guaiacila, unidade siringila e p-hidroxibenzoato.

Abstract This paper aimed to characterize the lignin in the cell wall of Euterpe oleracea Mart. Samples from two regions of the base of the palm were acquired: outer and inner regions (OR and IR, respectively). The extraction with organic solvents and the treatment with 1% NaOH were carried out. Holocellulose, α-cellulose and lignin content were quantified, the latter also isolated by the Björkman method for the structural characterization using 1H and 13C NMR in the liquid state, as well as spectroscopic (FTIR) and chromatographic analysis. The extracted stem had 10.33% (OR) and 15.66% (IR) of the lignin. After the treatment with 1% NaOH, a reduction in these values was observed, and it was also possible to confirm this result through the decrease in the intensities of the signals referring to the functional groups linked to lignin and hemicellulose. The spectroscopic and chromatographic analyzes revealed GS-type lignin incorporated with p-hydroxybenzoic and protocatechuic acid in both samples. The main structural units present in the lignin were also observed, such as β-O-4 bond, β-O-4’ ϒ-acetyl bond, guaiacyl unit, syringyl unit and p-hydroxybenzoate.

Abstract Background: Patients using immunosuppressive drugs may have unfavorable results after infections. However, there is a lack of information regarding COVID 19 in these patients, especially in patients with rheumatoid arthritis (RA). Therefore, the aim of this study was to evaluate the risk factors associated with COVID 19 hospitalizations in patients with RA. Methods: This multicenter, prospective cohort study is within the ReumaCoV Brazil registry and included 489 patients with RA. In this context, 269 patients who tested positive for COVID 19 were compared to 220 patients who tested negative for COVID 19 (control group). All patient data were collected from the Research Electronic Data Capture database. Results: The participants were predominantly female (90.6%) with a mean age of 53 ±12 years. Of the patients with COVID 19, 54 (20.1%) required hospitalization. After multiple adjustments, the final regression model showed that heart disease (OR =4.61, 95% CI 1.06–20.02. P < 0.001) and current use of glucocorticoids (OR =20.66, 95% CI 3.09–138. P < 0.002) were the risk factors associated with hospitalization. In addition, anosmia was associated with a lower chance of hospitalization (OR =0.26; 95% CI 0.10–0.67, P < 0.005). Conclusion: Our results demonstrated that heart disease and the use of glucocorticoids were associated with a higher number of hospital admissions for COVID 19 in patients with RA. Trial registration: Brazilian Registry of Clinical Trials RBR 33YTQC.

Abstract The use of tropical species in forest plantations is an alternative to supply the demand of good quality wood. However, information regarding the performance of planted tropical species is scarce. The aim of this study was to provide an assessment of the lumber potential of Cariniana legalis (“jequitibá-rosa”), Zeyheria tuberculosa (“ipê-felpudo”) and Cordia trichotoma (“louro-pardo”) in a forest plantation. Three trees per species were sampled at age of 50 months, planted in a mixed stand with 2 x 4 m spacing in Porto Seguro, Bahia, Brazil. We assessed characteristics of the trees, the logs, lumber yield, and partial volumetric shrinkage of wood. Total volumetric shrinkage of ipê-felpudo, jequitibá-rosa and louro-pardo would be around 12.80%, 13.40% and 11.58%, respectively. Among the three species analyzed, louro-pardo had the best performance, followed by ipê-felpudo, while jequitibá-rosa had the worst performance. All species had good performance regarding log quality and dimensional stability of wood.

Resumo O objetivo desse estudo foi analisar a capacidade das indústrias moveleiras da região metropolitana do Rio de Janeiro, em atender aos requisitos das certificações de cadeia de custódia do Forest Council Stewardship (FSC). Os dados foram coletados através da aplicação de questionários contendo informações sobre a certificação florestal (administração participativa, capacitação dos funcionários, documentação legal da empresa, fornecedores certificados, rastreabilidade da matéria-prima e relatório de movimentação de certificação). Os questionários foram preenchidos durante visitas às empresas, respondidos pelo responsável do setor de projeto e produção. Os requisitos “disposição de licenças e outros documentos legais”, “disponibilidade de um responsável pelo processo de certificação de cadeia de custódia” e “capacitação de funcionários”, que necessitam de custos e que exigem procedimentos burocráticos para cumprimento, foram os que mais interferiram para que as empresas não obtivessem o certificado de cadeia de custódia. O requisito-chave “rastreabilidade da matéria-prima” não apresentou complexidade de cumprimento, visto que todas as indústrias afirmaram ter capacidade em atendê-lo. Em relação à norma de certificação de cadeia de custódia, a maioria das indústrias moveleiras da região metropolitana do Rio de Janeiro consegue cumprir os requisitos exigidos.

Abstract This research aimed to analyze the ability of the Rio de Janeiro metropolitan furniture industries to meet the requirements of Forest Council Stewardship chain of custody certifications (FSC). Data were collected through the application of questionnaires containing information on forest certification (participatory management, employee training, company legal documentation, certified suppliers, raw material traceability and certification movement report). The questionnaires were completed during visits to the companies, answered by the head of the design and production sector. The requirements “provision of licenses” and “other legal documents”, “availability of chain of custody certification process officer” and “staff training”, which require costs and require bureaucratic compliance procedures, were the ones that influenced the companies not to obtain the chain of custody certificate. The key requirement “raw material traceability” did not present compliance complexity, as all industries claimed to be able to meet it. In the chain of custody certification standard, most furniture industries in the Rio de Janeiro metropolitan region can meet the required requirements.

OBJECTIVE: This study aimed to determine the personal and professional characteristics, and the physical, psychiatric/psychological, and professional issues that exist among master’s-, doctoral-, and post-doctoral-level health professionals. METHODS: A cross-sectional, online, self-reported survey of 452 postgraduates who completed master’s, doctoral, or post-doctoral degrees in one graduate program in pediatrics in São Paulo, Brazil, was conducted. RESULTS: The response rate was 47% (211/453). The majority of participants were women (78%) and physicians (74%), and the median age was 47 years (28-71). Master’s, doctoral, and post-doctoral degrees were reported by 73%, 53%, and 3%, respectively. High workload (>40 hours/week) occurred in 59%, and 45% earned ≥15 minimum wages/month. At least one participation in scientific meeting in the past year was reported by 91%, and 79% had published their research. Thirty-nine percent served as a member of a faculty of an institution of higher learning. The data were analyzed by two age groups: participants aged ≤48 years (group 1) and participants aged >48 years (group 2). The median rating of overall satisfaction with the profession in the past year [8 (0-10) vs. 9 (1-10), p=0.0113]; workload >40 hours/week (53% vs. 68%, p=0.034); and ≥15 minimum wages/month (37% vs. 56%, p=0.0083) were significantly lower in group 1. Further analysis by gender revealed that the median rating of overall satisfaction with the profession in the past year [8 (0-10) vs. 9 (3-10), p=0.0015], workload >40 hours/week (53% vs. 83%, p=0.0002), and ≥15 minimum wages/month (37% vs. 74%, p=0.0001) were significantly lower in women compared with men. The median rating of overall satisfaction with the mentorship supervision provided was significantly higher among the women 10 (5-10) vs. 10 (2-10), p=0.0324]. CONCLUSIONS: The majority of master’s-, doctoral-, and post-doctoral-level health professionals were women and physicians, and had published their thesis. Younger postgraduates and women reported low salaries, less likelihood of working >40 hours/week, and less overall satisfaction with their profession. Further longitudinal and qualitative studies are warranted to assess career trajectories after graduation.

ABSTRACT There is just little information about the technological aspects of the wood of Brazilian native tree species, which limits their suitable use. The objective of this study was to evaluate the resistograph amplitudes of the wood from six native tree species in different wood density classes, and correlate them with their wood densities to demonstrate the efficiency of this nondestructive technique. The results of the resistograph analysis divided the species into three classes. Analyses of basic and bulk densities of their wood showed statistically significant differences among the evaluated samples that divided them into four classes. The comparison of resistograph method and observed densities showed only a slight difference among the density classes. Therefore, it was found in this study that resistograph analysis may be used for explaining wood properties as well as achieving satisfactory correlations with their actual values, especially the physical properties of species with high wood density.

Abstract Objectives: This study sought to evaluate the impact of prosthesis-patient mismatch (PPM) on the risk of early-term mortality after transcatheter aortic valve implantation (TAVI). Methods: Databases (Medical Literature Analysis and Retrieval System Online [MEDLINE], Excerpta Medica dataBASE [EMBASE], Cochrane Controlled Trials Register [CENTRAL/CCTR], ClinicalTrials.gov, Scientific Electronic Library Online [SciELO], Latin American and Caribbean Literature on Health Sciences [LILACS], and Google Scholar) were searched for studies published until February 2019. PPM after TAVI was defined as moderate if the indexed effective orifice area (iEOA) was between 0.85 cm2/m2 and 0.65 cm2/m2 and as severe if iEOA ≤ 0.65 cm2/m2. Results: The search yielded 1,092 studies for inclusion. Of these, 18 articles were analyzed, and their data extracted. The total number of patients included who underwent TAVI was 71,106. The incidence of PPM after TAVI was 36.3% (25,846 with PPM and 45,260 without PPM). One-year mortality was not increased in patients with any PPM (odds ratio [OR] 1.021, 95% confidence interval [CI] 0.979-1.065, P=0.338) neither in those with moderate PPM (OR 0.980, 95% CI 0.933-1.029, P=0.423). Severe PPM was separately associated with high risk (OR 1.109, 95% CI 1.041-1.181, P=0.001). Conclusion: The presence of severe PPM after TAVI increased early-term mortality. Although moderate PPM seemed harmless, the findings of this study cannot not rule out the possibility of it being detrimental, since there are other registries that did not address this issue yet.

RESUMO Objetivou-se neste trabalho determinar o perfil da densidade aparente em painel aglomerado confeccionado com partículas da madeira de Acacia mangium. Utilizou-se a técnica de microdensitometria de raios X correlacionada com a densidade gravimétrica. Foram utilizados os adesivos ureia formaldeído e tanino comercial de Acacia mearnsii aplicado na forma de pó diretamente nas partículas previamente encoladas. Os painéis foram fabricados com quatro razões de compactação (1,39; 1,55; 1,73; e, 2,00) combinadas a quatro proporções de tanino em pó (0, 10, 20 e 30%), totalizando 16 tratamentos (4 painéis por tratamento). Foram determinados, analisados e comparados o perfil da densidade aparente (densidade média, densidade máxima e densidade mínima) e a densidade gravimétrica dos aglomerados produzidos. O perfil da densidade é apresentado graficamente e interpretado por análise de variância e regressão linear múltipla. Os valores de densidade aparente média, máxima e mínima observados para os painéis aglomerados obtidos pela microdensitometria de raios X variaram de 357 a 697 kg/m3, 386 a 824 kg/m3 e 334 a 634 kg/m3, respectivamente, e pelo método gravimétrico de 369 a 742 kg/m3. A técnica mostrou-se eficiente na determinação de variações nos perfis de densidade aparente ao longo da espessura dos painéis em todos os tratamentos, bem como mostrou-se eficiente na obtenção direta da densidade aparente. Estas variações poderiam ser minimizadas se o tanino utilizado fosse anteriormente hidratado em água. Houve forte correlação entre as médias das densidades obtidas pelo método do microdensitômetro de raios X e pelo método gravimétrico.

ABSTRACT This study aimed to determine the apparent density, by gravimetric technique and X-ray microdensitometry of particleboard produced with Acacia mangium wood and search existence of correlation between both methods. It was used urea formaldehyde adhesive and commercial tannin Acacia mearnsii applied in powder form directly to the previously glued particles. The panels manufactured using four compression ratios (1.39, 1.55, 1.73, and 2.00) combined four levels of powdered tannin (0, 10, 20 and 30%), making up 16 treatments (4 panels by treatment). The particleboard apparent density parameters (mean, maximum and minimum) and gravimetric density were determined, analyzed and compared. The density profile presented graphically and interpreted by analysis of variance and multiple linear regression. The apparent density, medium, maximum and minimum for particleboard obtained by microdensitometry X-ray ranged 357-697 kg/m3, 386-824 kg/m3, and 334-634 kg/m3, respectively, and gravimetric method 369-742 kg/m3. The technique was effective in determining variations in the density profile in the thickness of the particleboards in all treatments, as well as direct obtain the apparent density. These variations could be reduced if the tannin used was previously hydrated in water. Was found strong correlation (R2 = 0.99) between the mean apparent density obtained by X-ray microdensitometer and gravimetric method.

RESUMO A criação de modelos virtuais tridimensionais é uma tecnologia promissora no planejamento pré-operatorio, entretanto não é utilizada no tratamento de fistulas anais. O objetivo desse trabalho é descrever o desenvolvimento e a experiência inicial da construção de um modelo virtual tridimensional da anatomia pélvica de um paciente, que permite a identificação exata das relações entre os tratos fistulosos de fistulas anais complexas e as demais estruturas pélvicas. O paciente realizou uma ressonância magnética e as imagens foram exportadas para o programa Vitrea fX software Workstation®. Um radiologista realizou a analise e segmentação das imagens que, em seguida, foram enviadas para um processador de imagens tridimensionais (Meshlab v. 1.3.3 – ISTI – CNR research center, Pisa University, Italy®). A imagem 3D colorida final foi analisada pelo cirurgião e utilizada para guiar a cateterização dos trajetos fistulosos e orifício interno e para auxiliar na identificação das estruturas adjacentes. O modelo tridimensional final apresentou alta correlação com os achados intraoperatorios e facilitou o planejamento cirúrgico.

ABSTRACT The making of three-dimensional virtual models is a promising technology in preoperative planning, but that is not used in the treatment of anorectal fistulas. The objective of this work is to describe the development and initial experience of the construction of a virtual three-dimensional model of the pelvic anatomy of a patient, allowing the exact identification of the relationships between the fistulous tracts of complex anorectal fistulas and the other pelvic structures. An MRI was performed on this patient, and the images were exported to the Vitrea fX Workstation® software. A radiologist did the analysis and segmentation of the images that were then sent to a three-dimensional image processor (Meshlab v. 1.3.3 – ISTI – CNR Research Center, Pisa University, Italy®). The final 3D color image was analyzed by the surgeon and used to guide the catheterization of the fistulous pathways, the internal orifice and to assist in the identification of adjacent structures. The final three-dimensional model presented a high correlation with the intraoperative findings and facilitated the surgical planning.

ABSTRACT The exploitation of valuable native timber species in forest restoration projects has emerged as a promising strategy to make restoration financially viable. There are few studies regarding the quality of timber from restoration plantations. The aim of this study was to analyze growth stresses by determining the longitudinal residual strain (LRS) and evaluate their correlation with the growth variables in the species Peltophorum dubium (Spreng.) Taub in a 14-year old restoration plantation. Eighteen individuals were evaluated, determining the following variables: diameter at breast height (DBH), bark thickness, average annual growth in diameter (IMA) and annual periodic growth in diameter (IPA 2012-2015 ). The LRS was determined by the extensometer (CIRAD-Forêt), on DBH height and in the north-south direction of each tree. The LRS average was 0.072 mm, within the range of expected wood values for sawmilling. There was a significant positive correlation between the LRS, DBH and IMA.
