Abstract In Jean Rouch’s meeting with Manoel de Oliveira, the latter situated him and his cinema as more African than European, and Jocelyne Rouch identified him with the title of the film Moi, un Noir (I, a Negro; Rouch, 1958) - that is him. Rouch is also an engineer at Ponts et Chaussées. No wonder his cinema reflects the poetry of iron and steel, as does Manoel de Oliveira’s. Rouch’s bridges and paths are also connecting people, cultures and societies. The relationship of the real as imagined in his films - fascination with authentic Dogon rites and possession phenomena and modern anthropology focused on displaced people, migrants living in big cities, and urban life - is thus remarkable. This text seeks to address four dimensions of Jean Rouch’s path: situating him in the context of ethnographic film, revisiting the archives of Chronique d’un Été (Chronicle of a Summer; Rouch & Morin, 1960) 50 years after it was produced, Rouch’s meeting with the Dogon and the “poetry of iron and steel” shared with Manoel de Oliveira, referring to his dimension as an engineer, filmmaker and anthropologist. Other equally important dimensions were left out, for they do not fit into this reflection1.

Resumo No encontro de Jean Rouch com Manoel de Oliveira, este situou-o e situou o seu cinema como mais africano que europeu e Jocelyne Rouch identificou-o com o título do filme Moi, un Noir (Eu, um Negro; Rouch, 1958) - é ele. Rouch é também engenheiro de pontes e estradas. Não admira, pois, que a poética do ferro e do aço esteja presente no seu cinema, ao lado de Manoel de Oliveira. As pontes e os caminhos de Rouch são também entre pessoas, culturas, sociedades. É, pois, notável a relação do real como imaginado nos seus filmes - o fascínio pelos rituais autênticos dos dogon e os fenómenos de possessão e uma antropologia moderna virada para as pessoas deslocadas, migrantes que viviam em grandes cidades, e para a vida urbana. Procuramos abordar neste texto quatro dimensões do percurso de Jean Rouch: situá-lo no contexto do filme etnográfico, revisitar os arquivos de Chronique d’un Été (Crónica de um Verão; Rouch & Morin, 1960) 50 anos depois de sua realização, o encontro de Rouch com os dogon e a “poética do ferro e do aço” partilhada com Manoel de Oliveira, remetendo para sua dimensão de engenheiro, cineasta e antropólogo, consciente de que ficaram de fora dimensões igualmente importantes, mas que não cabem nesta reflexão1.

Abstract Introduction Malignant Hyperthermia (MH) is a pharmacogenetic, hereditary and autosomal dominant syndrome triggered by halogenates/succinylcholine. The In Vitro Contracture Test (IVCT) is the gold standard diagnostic test for MH, and it evaluates abnormal skeletal muscle reactions of susceptible individuals (earlier/greater contracture) when exposed to caffeine/halothane. MH susceptibility episodes and IVCT seem to be related to individual features. Objective To assess variables that correlate with IVCT in Brazilian patients referred for MH investigation due to a history of personal/family MH. Methods We examined IVCTs of 80 patients investigated for MH between 2004‒2019. We recorded clinical data (age, sex, presence of muscle weakness or myopathy with muscle biopsy showing cores, genetic evaluation, IVCT result) and IVCT features (initial and final maximum contraction, caffeine/halothane concentration triggering contracture of 0.2g, contracture at caffeine concentration of 2 and 32 mmoL and at 2% halothane, and contraction after 100 Hz stimulation). Results Mean age of the sample was 35±13.3 years, and most of the subjects were female (n=43 or 54%) and MH susceptible (60%). Of the 20 subjects undergoing genetic investigation, 65% showed variants in RYR1/CACNA1S genes. We found no difference between the positive and negative IVCT groups regarding age, sex, number of probands, presence of muscle weakness or myopathy with muscle biopsy showing cores. Regression analysis revealed that the best predictors of positive IVCT were male sex (+12%), absence of muscle weakness (+20%), and personal MH background (+17%). Conclusions Positive IVCT results have been correlated to male probands, in accordance with early publications. Furthermore, normal muscle strength has been confirmed as a significant predictor of positive IVCT while investigating suspected MH cases.

Abstract This paper describes the automation of a forearm prosthesis using the signal collected by a Fiber Bragg Grating (FBG) sensor. The FBG sensor is applied to one subject's forearm to measure the deformation as a result of the index and middle fingers when moved individually. It is possible to control a one joint model prosthesis allied to a compliant hand mechanism through signal analyses. Each finger movement has its features, such as its amplitude, which opens the possibility of using those to control different parts of the prosthesis, joint rotation by the middle finger, and compliant hand movement by the index finger. This paper presents results regarding prosthesis assembling, Hypertext Transfer Protocol (HTTP) communication latency between prosthesis and computer and tests with pre-acquired and processed FBG signal data. The prosthesis wrist rotation movement is related to the middle finger signal, and its compliant mechanism actuation is due to index finger signal. The communication between prosthesis and the computer had a mean latency of 140 ms and a standard deviation of 18 ms. The results demonstrate the potential for using the sensor system and automated prosthesis in other applications involving real-time forearm sensing, multi-finger signal analysis, and prosthetic movement.

Abstract In this work, measuring capabilities of a Sagnac Interferometer-based Distributed Optical Fiber Sensor (DOFS) system are demonstrated by comparing its results to a conventional amplitude-based Distributed Acoustic Sensing (DAS) system. Through a set of three different experiments, it was demonstrated that both sensing systems can detect and locate dynamical deformation along the fiber, in addition to determining its frequency components. The coherent amplitude-based DAS presented a lower background noise. In contrast, even though the Sagnac interferometry-based system presented low-frequency noise in the measurements, it is less susceptible to harmonic distortion for higher amplitude deformations since its sensing principles rely on the measurement of the accumulated phase rather than the amplitude of the backscattered signal purely. Accordingly, the Sagnac interferometry-based system arises as a promising and rather accessible topology for a DOFS implementation. work Interferometerbased Interferometer based (DOFS amplitudebased (DAS experiments fiber components contrast interferometrybased interferometry lowfrequency low measurements purely Accordingly implementation

Abstract: Eucalyptus planted forests contribute to maximizing lumber production but problems such as longitudinal growth strain can negatively influence the quality of the products. Knowing dendrometric variables and wood properties can help in the prediction of longitudinal growth strain, mainly with the help of artificial intelligence. Thus, the aim of this research was to evaluate the use of artificial neural networks to predict longitudinal growth strain in Eucalyptus trees based on dendrometric variables, spacing between trees and wood density. The longitudinal growth strain was measured in trees of four Eucalyptus clones planted in three spacings. The diameter and height of each tree were measured. The basic wood density was determined. Artificial neural networks were used to estimate longitudinal growth strain as a function of dendrometric variables, tree spacing and wood density. The results showed that the artificial neural networks presented good results for training and validation, with most of them resulting in high correlation coefficient values. The trained artificial neural networks showed a correlation coefficient above 0,56. Artificial neural networks showed that the variables clone and basic wood density were the ones that most contributed to the prediction of longitudinal growth strain. On the other hand, the spacing between trees, the height of the tree and the diameter at breast height were not relevant to predict growth stresses.

ABSTRACT. Emulsifiers in animal diets are an interesting and effective strategy for nutritionists to improve the digestion of dietary lipids and, consequently, provide better performance. This study aimed to evaluate the effect of the supplementation of diets with emulsifier based on mono- and diglycerides (120 g t-1 of feed) associated with different energy levels (2,775; 2,725; 2,675 and 2,625 kcal of metabolizable energy kg-1 of feed) on performance and egg quality of Hisex Brown laying hens. The laying hens were distributed in 50 experimental plots with eight birds each. A completely randomized design with five treatments and ten replicates/treatments was used. The treatments in this study were: control diet (C) with 2,775 kcal of metabolizable energy (ME) kg-1 of feed; C + E: diet C supplemented with an emulsifier (E) at 120 g t-1 of feed; diet C with reduction of 50 kcal ME and supplemented with E (NC50 + E); diet C with reduction of 100 kcal ME and supplemented with E (NC100 + E); and diet C with reduction of 150 kcal ME and supplemented with E (NC150 + E). All diets had the same inclusion level of degummed soybean oil (2%). There was no influence of the treatments on the performance and quality of the eggs (p >0.05). The current study has shown that diets supplemented with emulsifiers based on mono- and diglycerides (120 g t-1) allows reducing the metabolizable energy level up to 150 kcal kg-1 of feed, without impairment on performance and egg quality of Hisex Brown laying hens.

Abstract In addition to destroying the leaves, stems, pods, and grains of soybean (Glycine max), Spodoptera frugiperda larvae may also have the cut off behavior in the seedlings close to the ground, harming the establishment of the soybean crop. Therefore, this study aimed to evaluate the consequences of the fall armyworm attack by adopting the cut off behavior, which has been similarly documented for black cutworm (Agrotis ipsilon) in newly emerged soybean plants. The treatments were five levels of infestation with 0, 5, 10, 20 and 40 larvae per m2. Three variables were assessed: (1) stand (relationship between attacked and initial number of plants), (2) types and amounts of injured structures, such as hypocotyl (embryonic shoot), and the cotyledons (seed leaves), and (3) level of defoliation. The variables were collected every 24 hours until the pupal stage. Additionally, the final stand of the seedlings was quantified, with the highest injury intensity observed in the plots that contained the highest number of larvae. In the second experiment, the dynamics of movement and attacks of plants by S. frugiperda larvae at the following times of the day: 07:00, 10:00, 13:00, 16:00, 19:00 and 21:00 were analyzed with supervised machine learning models. The injury caused by S. frugiperda with the behavior of the cut off and the voracity of the larvae were evident in the structures (hypocotyl and cotyledons) of the evaluated plants. The results of the present study emphasize the need to manage S. frugiperda during the preplanting phase of soybean.

Abstract Background Atrial fibrillation (AF) is the most common arrhythmia in patients with end-stage renal disease (ESRD). The coexistence of high thromboembolic and hemorrhagic risks, added to the lack of strong scientific evidence on the safety of anticoagulants in the setting of renal failure, makes this a clinically challenging situation. Objectives To describe the clinical-demographic profile and prevalence of AF in the population with ESRD undergoing dialysis. Secondary objectives include the assessment of thromboembolic (CHA2DS2VASC) and bleeding (HASBLED) risk scores. Methods Cross-sectional analytical-descriptive study, carried out between January and March 2020. Patients with ESRD were evaluated by means of a medical history questionnaire, physical examination, and 12-lead electrocardiogram. A chi-square (χ2) association test was applied to calculate association between clinical variables and AF, with a significance level of α = 0.05. Results This study evaluated 295 patients, most of whom were men (170), elderly (63, IQR 53-71), current smokers (130), with associated cardio-endocrine comorbidities. The prevalence of AF was 6.7% (20). Heart failure (HF) (χ2=15.417; p<0.001), age of 65 years or older (χ2=14.584; p<0.001), and anticoagulation (χ2=5.715; p<0.01) were associated with AF. The median CHA2DS2VASC and HASBLED was 4 and 3, respectively. Eight patients were taking warfarin and five were receiving apixaban. Conclusion The prevalence of AF in this study is similar to that reported in other published articles on the subject, and patients were at high risk for cardiovascular outcomes. Non-anticoagulation strategy was commonly adopted due to controversies in the literature as well as the absence of published randomized clinical trials.

Abstract The aim of this study was to describe the prevalence, clinicopathological, and prognostic features of acinic cell carcinoma (AciCC) of the oral and maxillofacial region. AciCC cases were retrospectively retrieved from 11 pathology centers of three different countries. Medical records were examined to extract demographic, clinical, pathologic, and follow-up information. A total of 75 cases were included. Females (65.33%) with a mean age of 45.51 years were mostly affected. The lesions usually presented as an asymptomatic (64.28%) nodule (95.66%) in the parotid gland (70.68%). The association of two histopathological patterns was the most common finding (48.93%) and the tumors presented mainly conventional histopathological grades (86.11%). Surgical treatment was performed in the majority of the cases (59.19%). Local recurrence was observed in 20% of the informed cases, regional metastasis in 30.43%, and distant metastasis in 12.50%. The statistical analysis showed that the cases with a solid histopathological pattern (p=0.01), high-grade transformation (p=0.008), recurrence (p=0.007), and regional metastasis (p=0.03) were associated with poor survival. In conclusion, high histopathological transformation, presence of nodal metastasis, and recurrence were prognostic factors for AciCC of the oral and maxillofacial region.

In this study, a hydroxyapatite (HA) coating derived from the scales of the Amazonian fish pirarucu (Arapaima gigas) was produced using calcination at 500 and 750 °C and deposited on AISI 316 stainless steel substrate using the process of thermal spraying, high velocity suspension plasma spray (HVSPS). To verify its potential, this material was characterized by X-ray diffraction (XRD), by which characteristic peaks of hydroxyapatite were evidenced. Via X-ray fluorescence (XRF) of the samples, it was observed that the Ca/P ratio was equal to 2.00. Using the Fourier transform infrared (FTIR) spectroscopy and Raman spectroscopy, it was possible to observe the characteristic bands of the HA. For the coating, the mechanical nanoindentation test showed mean Vickers microhardness (VH) values of 93.25 VH for the hydroxyapatite and of 196.57 HV for the substrate. The modulus of elasticity (EIT) was 77.85 GPa for the hydroxyapatite coating and 136.45 GPa for the substrate. Optical microscopy showed that the coating was homogeneously deposited.

ABSTRACT Background: The aim of this research was to investigate the efficiency of methods to overcome primary dormancy and biochemical processes associated with germination of Erythrina falcata Benth seeds. Seeds were submitted to dormancy overcoming treatments and the water uptake pattern was analysed. We then evaluated the activity of the antioxidant enzymes SOD, CAT, and APX, and quantified lipid peroxidation levels, hydrogen peroxide content and total protein content. The experiments were performed in a completely randomized design and the statistical analysis used was Scott-Knott test at 5% probability. Results: Mechanical scarification with sandpaper leads to approximately 94% of germination in E. falcata, while control non-scarified seeds show only approximately 37% of germination. Treatments with hot water led to high mortality in E. falcata seeds. Rapid water absorption was observed in the first 18 hours of imbition when the seeds were scarified with sandpaper, and radicle emergence was observed after 36 hours. During imbibition there was an increase of antioxidant enzyme activity and a decrease in lipid peroxidation and H2O2 production, suggesting an efficient mechanism for regulating imbibition damage. A decrease in the total protein content was observed during germination of E. falcata seeds. Conclusions: Mechanical scarification is an efficient method for breaking dormancy of E. falcata seeds. During germination of E. falcata seeds there is a reduction in the production of H2O2 and lipid peroxidation, and an increase in the activity of antioxidant enzymes. The total protein content decreased along the germination time.

ABSTRACT Background: classical models of microsurgical anastomosis training are expensive and have ethical implications. Some alternatives join low cost and easiness to store. However, the translation of knowledge acquired by training in these methods into the traditional ones is not clear. This project aims to assess the feasibility of konjac noodles as a reliable microsurgery-training model. Methods: 10 neurosurgery residents performed an end-to-end anastomosis in a 2-3mm placenta artery. The anastomoses were evaluated quantitatively, recording time; and qualitatively, applying a validated score (Anastomosis Lapse Index - ALI) by three experienced neurosurgeons and verifying the presence of gross leakage through the infusion of fluorescein. Subsequently, they performed 10 non-consecutive sessions of anastomosis training in the konjac noodle. Eventually, a final anastomosis in the placenta model was performed and the same parameters were scored. Results: we observed a 17min reduction in the mean time to perform the anastomosis in the placenta model after the training in the konjac (p<0.05). There was a non-significant 20% reduction in gross leakage, but the training sessions were not able to consistently improve the ALI score. Conclusions: we demonstrate a reduction in anastomosis performing time in placental arteries after training sessions in the konjac noodle model, which can be regarded as a feasible low-cost method, particularly useful in centers with surgical microscopes only in the operation room.

ABSTRACT Introdução: modelos tradicionais de treinamento de anastomose microcirúrgica costumam ter custos elevados e implicações éticas de aquisição e manutenção, buscando-se alternativas que reúnam baixo custo e facilidade de armazenamento. Existem diferentes propostas, porém há poucas evidências de que conhecimentos adquiridos com o treinamento nessas plataformas se traduza em melhora na performance, quando estes são comparados a modelos consagrados. Este projeto objetiva avaliar a viabilidade do macarrão de konjac como modelo confiável de treinamento microcirúrgico. Métodos: 10 residentes de neurocirurgia realizaram uma anastomose término-terminal em artéria placentária humana de 2-3mm. As anastomoses foram avaliadas quantitativamente, registrando-se o tempo de confecção e qualitativamente, aplicando-se um escore validado (Anastomosis Lapse Index – ALI) por neurocirurgiões experientes e verificando-se a presença de vazamento grosseiro através da visualização no modo fluorescente injetando-se fluoresceína. Subsequentemente, realizaram 10 sessões de treinamento não consecutivos de anastomose términoterminal no modelo de konjac. Por fim, uma anastomose final foi realizada no modelo placentário e os mesmo parâmetros reavaliados. Resultados: observamos uma redução de 17 min no tempo médio de confecção da anastomose no modelo de placenta após os treinos no modelo do macarrão (p<0.05). Houve uma redução não significativa de 20% no vazamento grosseiro. As sessões de treino no macarrão não foram capazes de melhorar consistentemente o score ALI. Conclusão: o treinamento em modelo de macarrão konjac é capaz de reduzir o tempo para realização das anastomoses no modelo em placenta humana, mostrando-se alternativa viável de baixo custo e manutenção, útil em serviços que disponham de microscópio apenas no ambiente cirúrgico.

Abstract Neurological disorders in cattle comprise a group of economically relevant diseases with high occurrence and mortality. In this way, the objective was to carry out an epidemiological study of the diseases with neurological manifestations in cattle admitted (alive or dead) to the Garanhuns Bovine Clinic/Federal Rural University of Pernambuco (CBG/UFRPE) from January 2009 to December 2019. Epidemiological information was collected from the clinical records regarding the age group, rearing system, time of year, and area of origin of the animals. The diseases were grouped into categories according to their origin: toxic or toxi-infectious, viral, traumatic/physical, parasitic, metabolic degenerative, bacterial, neoplastic, and others. A total of 6103 cattle were treated during the study period, of which 604 (10.1%) were diagnosed with diseases that had neurological manifestations. Of these, 331 cases were of single occurrence, and 231 cases occurred as outbreaks in the herd. Death was the outcome in almost 80% of the cases (465/596). The frequencies of the different categories were toxic or toxi-infectious (25.2%), viral (21.5%), traumatic/physical (13.6%), parasitic (9.8%), metabolic (9.3%), degenerative (2.3%), bacterial (2.2%), neoplastic (1.2%), and others (1.2%). It was found that almost half of the animals were older than 24 months (229/475), almost 80% were females, more than 60% were submitted to a semi-intensive to intensive rearing system, and the occurrence of disease was higher during the dry period of the year (363/614). The three most frequent neurological diseases in this study were rabies, trauma, and botulism.

Resumo Os distúrbios neurológicos em bovinos abrangem um grupo de enfermidades economicamente relevantes de elevada ocorrência e mortalidade. Desta forma, objetivou-se realizar um estudo epidemiológico das enfermidades que cursaram com manifestações neurológicas que deram entrada (vivos ou mortos) na Clínica de Bovinos de Garanhuns/Universidade Federal Rural de Pernambuco no período de janeiro de 2009 a dezembro de 2019. Nos prontuários clínicos, foram coletadas informaçõe epidemiológicas referentes ao sexo; a faixa etária; ao sistema de criação, época do ano e a área de procedência dos animais. As doenças foram agrupadas em categorias de acordo com sua origem: tóxica ou toxi-infecciosa, viral, traumática, parasitária, degenerativa, metabólica, bacteriana, neoplásica e outras. Um total de 6103 bovinos foram atendidos no período estudado, dos quais 604 (10,1 %) foram diagnosticados com enfermidades que cursaram com manifestações neurológicas. Destes, 331 casos foram de ocorrência individual, 231 casos cursaram como surtos no rebanho. Quase 80% dos casos (465/596) teve o óbito como desfecho. As frequências das distintas categoria foram tóxica ou toxi-infecciosa (25,2%), viral (21,5%), traumática/física (13,6%), parasitária (9,8%), metabólica (9,3%, degenerativa (2,3%), bacteriana (2,2%), neoplásica (1,2%), outras (1,2%). Verificou-se que quase metade dos animais apresentavam idade superior a 24 meses (229/475), quase 80% eram fêmeas, mais de 60% eram submetidos a um sistema de criação de semi-intensivo a intensivo e a ocorrência foi maior durante o período seco do ano (363/614). As três enfermidades com manifestações neurológicas de maior ocorrência neste estudo foram a raiva, os traumatismos e o botulismo.

Abstract This study aimed to identify clinical and laboratory variables that could help predict the negative outcome in cattle affected by gastrointestinal emergencies. A retrospective cohort study was carried out using multivariate logistic regression analysis based on data collected from the clinical records of cattle hospitalized at the Garanhuns Bovine Clinic, UFRPE campus. One hundred and twenty-two cattle met the inclusion criteria established for the study. Among the clinical variables, heart rate (HR) and abdominal distension are associated with the outcome in animals with right displaced abomasum (RDA), and anorexia and 10% dehydration in animals with an obstructive intestinal disorder. Among the laboratory variables, plasma fibrinogen (PF) and total leukocyte count were associated with the outcome in animals with RDA, while PF and plasma L-lactate were associated with animals with an obstructive intestinal disorder. HR and the total leukocyte count remained in the final model of the regression adjusted for animals with RDA. On the other hand, plasma L-lactate and PF remained in the final model in the adjusted model for animals with an obstructive intestinal disorder. Cattle with RDA and HR higher than 90 bpm present an increased chance of having a negative outcome whereas cattle with obstructive intestinal disorder and plasma L-lactate higher than 1.84 mmol/L or PF higher than 850 mg/dL have a higher chance of not survive. Therefore, clinical and laboratory variables such as HR, fibrinogen, and plasma L-lactate are useful to predict the negative outcome in cattle with gastrointestinal emergencies, especially RDA and obstructive intestinal disorders.

Resumo Este estudo teve como objetivo identificar variáveis clínicas e laboratoriais que pudessem ajudar a predizer o desfecho negativo em bovinos acometidos por emergências gastrointestinais. Foi realizado um estudo de coorte retrospectivo por meio de análise de regressão logística multivariada com base em dados coletados dos prontuários de bovinos internados na Clínica de Bovinos de Garanhuns, campus da UFRPE. Cento e vinte e dois bovinos atenderam aos critérios de inclusão estabelecidos para o estudo. Dentre as variáveis clínicas, a frequência cardíaca e a distensão abdominal estão associadas ao desfecho em animais com deslocamento de abomaso à direita (DAD), e anorexia e 10% de desidratação em animais com distúrbio intestinal obstrutivo. Entre as variáveis laboratoriais, o fibrinogênio plasmáticao (FP) e a contagem total de leucócitos foram associados ao desfecho em animais com DAD, enquanto o FP e o L-lactato plasmático foram associados a animais com distúrbio intestinal obstrutivo. A frequência cardíaca (FC) e a contagem total de leucócitos permaneceram no modelo final da regressão ajustada para animais com DAD. Por outro lado, o L-lactato plasmático e o FP permaneceram no modelo final ajustado para animais com distúrbio intestinal obstrutivo. Bovinos com DAD e FC maior que 90 bpm apresentam maior chance de ter um desfecho negativo, enquanto bovinos com distúrbio intestinal obstrutivo e L-lactato plasmático maior que 1,84 mmol/L ou FP maior que 850 mg/dL têm maior chance de não sobreviver. Portanto, variáveis clínicas e laboratoriais como FC, FP e L-lactato plasmático são úteis para predizer o desfecho negativo em bovinos com doenças emergências gastrointestinais, especialmente DAD e distúrbios intestinais obstrutivos.

Abstract This study aimed to evaluate the contribution of oral and maxillofacial pathology laboratories (OMPLs) in Brazilian public universities to the diagnosis of lip, oral cavity, and oropharyngeal squamous cell carcinoma (SCC). A cross-sectional study was performed using biopsy records from a consortium of sixteen public OMPLs from all regions of Brazil (North, Northeast, Central-West, Southeast, and South). Clinical and demographic data of patients diagnosed with lip, oral cavity, and oropharyngeal SCC between 2010 and 2019 were collected from the patients’ histopathological records. Of the 120,010 oral and maxillofacial biopsies (2010-2019), 6.9% (8,321 cases) were diagnosed as lip (0.8%, 951 cases), oral cavity (4.9%, 5,971 cases), and oropharyngeal (1.2%, 1,399 cases) SCCs. Most cases were from Brazil’s Southeast (64.5%), where six of the OMPLs analyzed are located. The predominant profile of patients with lip and oral cavity SCC was Caucasian men, with a mean age over 60 years, low schooling level, and a previous history of heavy tobacco consumption. In the oropharyngeal group, the majority were non-Caucasian men, with a mean age under 60 years, had a low education level, and were former/current tobacco and alcohol users. According to data from the Brazilian National Cancer Institute, approximately 9.9% of the total lip, oral cavity, and oropharyngeal SCCs reported over the last decade in Brazil may have been diagnosed at the OMPLs included in the current study. Therefore, this data confirms the contribution of public OMPLs with respect to the important diagnostic support they provide to the oral healthcare services extended by the Brazilian Public Health System.
