ABSTRACT Since prehistoric times, indigenous communities have relied on fish as a staple source of protein for their subsistence. In most cases, fish is the sole source of income and of animal protein for the communities. Nevertheless, the documentation of fish from an ethnological perspective is rare, and biological research alone might not provide sufficient information required to manage fisheries resources. We discuss the traditional ichthyological knowledge of the Piapoco, Piaroa, Puinave, and Sikuani ethnic groups inhabiting the Matavén Forest (Vichada, Colombia). Each group has its perception regarding knowledge, at times detailed, of fish groups, their distribution, and uses. To obtain information regarding traditional ichthyological knowledge, fish were collected over one month at 31 sampling sites in different habitats along the lower Matavén River basin. The fish were identified by formal taxonomy and the informal classification by experienced fishermen of the four ethnic groups. There was consistency among the names given by the ethnic groups and formal taxonomy. The indigenous collaborators used binomial classification systems in which the organisms are grouped at family and genus levels and, to some extent, categorization depends on distribution within the aquatic habitats (i.e., rivers, streams and lagoons). The indigenous collaborators did not provide sociocultural or mythological information related to the fishes. Our findings contribute to the development of conservation and rural development projects in the Colombian Amazon.

RESUMEN Desde la prehistoria, las comunidades indígenas han dependido del pescado como fuente primaria de proteína para su subsistencia. En la mayoría de los casos, el pescado es la única fuente de ingresos y proteína animal para la comunidad. Sin embargo, el estudio de los peces desde una perspectiva etnológica no es común y la investigación científica por sí sola puede no proporcionar información suficiente para gestionar los recursos pesqueros. Se discute aquí el conocimiento ictiológico tradicional de las etnias Piapoco, Piaroa, Puinave y Sikuani que habitan la Selva de Matavén (Vichada, Colombia). Cada etnia tiene una percepción propia, a veces detallada, de los grupos de peces, su distribución y usos. Para obtener información sobre el conocimiento ictiológico tradicional, se colectaron peces durante un mes en 31 sitios de muestreo en diferentes hábitats en la cuenca baja del Río Matavén. Los peces fueron identificados usando taxonomía formal y clasificación informal por pescadores expertos de las cuatro etnias. Hubo coherencia entre los nombres dados por los grupos étnicos y el sistema de taxonomía formal. Los colaboradores indígenas usaron sistemas de clasificación binomial en los que los organismos se agrupan a nivel de familia y género y la categorización depende, hasta cierto punto, de la distribución dentro de los hábitats acuáticos (ríos, arroyos y lagunas). Los colaboradores indígenas no proporcionaron información sociocultural o mitológica relacionada con los peces. Nuestros hallazgos contribuyen al desarrollo de proyectos de conservación y desarrollo rural en la Amazonía colombiana.

ABSTRACT BACKGROUND: The effect of weight loss (WL) on histopathological aspects of non-alcoholic fatty liver disease (NAFLD) may provide further insights into the dynamics of hepatic recovery after WL. OBJECTIVE: To analyze the effects of pre-operative WL on insulin resistance- and NAFLD-related histology in individuals undergoing bariatric surgery (BS) with or without pre-operative WL. DESIGN AND SETTING: A matched cross-sectional study was conducted at a public university hospital and a private clinic in Campinas, Brazil. METHODS: An analytical, observational, cross-sectional study was conducted using prospectively collected databases of individuals who underwent BS and liver biopsy at either a public tertiary university hospital (with pre-operative WL) or a private clinic (without pre-operative WL). Random electronic matching by gender, age, and body mass index (BMI) was performed and two paired groups of 24 individuals each were selected. RESULTS: Of the 48 participants, 75% were female. The mean age was 37.4 ± 9.6. The mean BMI was 38.9 ± 2.6 kg/m2. Fibrosis was the most common histopathological abnormality (91.7%). Glucose was significantly lower in the WL group (92 ± 19.1 versus 111.8 ± 35.4 mg/dL; P = 0.02). Significantly lower frequencies of macrovesicular steatosis (58.3% versus 95.8%; P = 0.004), microvesicular steatosis (12.5% versus 87.5%; P < 0.001), and portal inflammation (50% versus 87.5%; P = 0.011) were observed in the WL group. CONCLUSION: Pre-operative WL was significantly associated with lower frequencies of macro- and mi- crovesicular steatosis, portal inflammation, and lower glycemia, indicating an association between the recent trajectory of body weight and histological aspects of NAFLD.

Abstract Background Detailed information about the electromyography practice in Brazil is largely unavailable. Objective To evaluate where and how electromyography is performed in Brazil, as well as regional disparities and the professional and academic credentials of electromyographers. Methods We conducted an internet-based survey of active Brazilian electromyographers. The websites of health insurance companies, professional academies, medical cooperatives, online search engines, and social networks in each Brazilian state were screened and we evaluated the credentials of each electromyographer listed in the Brazilian Federal Medical Board (BFMB) registration website and their online curricula vitae in the Brazilian National Council for Scientific and Technological Development (Conselho Nacional de Desenvolvimento Científico e Tecnológico, CNPq, in Portuguese). We also evaluated the same parameters in a control group of non-electromyographer neurologists randomly matched by geographical distribution and gender. Results We found 469 electromyographers (384 neurologists and 85 non-neurologists), with a male predominance. In total, 81.9% were BFMB-certified neurologists, 49.9%, BFMB-certified clinical neurophysiologists, and 10.4%, BFMB-certified physiatrists. Among the non-neurologists, 48.2% were physiatrists. Most electromyographers practiced in states on the Southern and Southeastern regions of Brazil. When adjusted by population, the Federal District and the states of Mato Grosso do Sul and Goiás presented the highest of eletromyographers density. Electromyographers were not more likely to have current/past academic affiliations. Conclusion In Brazil, electromyography is performed predominantly by neurologists, and half of them are BFMB-certified clinical neurophysiologists. The present study highlights regional disparities and may guide government-based initiatives, for instance, to improve the diagnosis of leprosy and the management of neuromuscular disorders within the Brazilian territory.

Resumo Antecedentes Informações detalhadas sobre a prática de eletromiografia no Brasil são em grande parte indisponíveis. Objetivo Avaliar onde e como a eletromiografia é realizada no Brasil, as disparidades regionais, e as credenciais profissionais e acadêmicas dos eletromiografistas. Métodos Realizamos uma enquete via internet de eletromiografistas brasileiros ativos. Foram rastreados sites de operadoras de planos de saúde, academias profissionais médicas, cooperativas médicas, ferramentas de busca online e redes sociais em cada estado brasileiro. Em seguida, avaliamos as credenciais de cada eletromiografista listado no site de registro do Conselho Federal de Medicina (CFM) e seus curricula vitae online no Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq). Também avaliamos os mesmos parâmetros em um grupo controle de neurologistas não eletromiografistas pareados aleatoriamente por distribuição geográfica e gênero. Resultados Encontramos 469 eletromiografistas (384 neurologistas e 85 não neurologistas), com predominância do sexo masculino. Ao todo, 81,9% eram neurologistas com certificação confirmada pelo site do CFM, 49,9%, neurofisiologistas clínicos com certificação confirmada pelo site do CFM, e 10,4%, fisiatras com certificação confirmada pelo mesmo site. Entre os não neurologistas, 48,2% eram fisiatras. A maioria dos eletromiografistas atuava nos estados do Sul e do Sudeste. Quando ajustados pela população, o Distrito Federal e os estados de Mato Grosso do Sul e Goiás apresentaram a maior densidade de eletromiografistas. Os eletromiografistas não eram mais propensos a ter vínculos acadêmicos atuais/passados. Conclusão No Brasil, a eletromiografia é realizada predominantemente por neurologistas, e metade deles são neurofisiologistas clínicos com certificação confirmada pelo site do CFM. Este estudo destacou as disparidades regionais, e pode orientar ações governamentais para, por exemplo, melhorar o diagnóstico da hanseníase e o manejo das doenças neuromusculares no território brasileiro.

Resumo Objetivo: Avaliar os valores máximo e médio de captação padronizada, o valor metabólico do tumor e a glicólise total da lesão do local do tumor primário, medidos no estudo de 18F-FDG-PET/CT realizado antes e depois da quimiorradioterapia neoadjuvante (nQRT) em pacientes com câncer de esôfago, como preditores de doença residual (DR). Materiais e Métodos: Os valores máximo e médio de captação padronizada e os parâmetros volumétricos (valor metabólico do tumor e glicólise total da lesão) da 18F-FDG-PET/CT realizada em 39 pacientes antes e após a nQRT para carcinoma de esôfago foram avaliados para RD. Usamos curvas receiver operating characteristic (ROC) para analisar o desempenho diagnóstico dos parâmetros 18F-FDG-PET/CT na definição de RD. O estudo anatomopatológico foi utilizado como padrão ouro. Resultados: Dezoito pacientes (46%) apresentaram DR após a nQRT. Áreas estatisticamente significativas sob a curva ROC para predizer DR foram obtidas para as quatro variáveis nos estudos realizados após a nQRT, com áreas sob a curva ROC semelhantes em torno de 0,72. Considerando a presença de captação visualmente detectável (captação maior que o background) no local da lesão primária após a nQRT como resultado positivo, teríamos uma sensibilidade de 94% e uma especificidade de 48% para detecção de DR. Conclusão: A 18F-FDG-PET/CT pode ser útil para detectar a presença de doença neoplásica residual no câncer de esôfago após a nQRT.

Abstract Objective: To evaluate the maximum and mean standardized uptake values, together with the metabolic tumor value and the total lesion glycolysis, at the primary tumor site, as determined by 18F-fluorodeoxyglucose positron-emission tomography/computed tomography (18F-FDG-PET/CT), performed before and after neoadjuvant chemoradiotherapy (nCRT), as predictors of residual disease (RD) in patients with esophageal cancer. Materials and Methods: The standardized uptake values and the volumetric parameters (metabolic tumor value and total lesion glycolysis) were determined by 18F-FDG-PET/CT to identify RD in 39 patients before and after nCRT for esophageal carcinoma. We used receiver operating characteristic curves to analyze the diagnostic performance of 18F-FDG-PET/CT parameters in the definition of RD. The standard of reference was histopathological analysis of the surgical specimen. Results: Eighteen patients (46%) presented RD after nCRT. Statistically significant areas under the curve (approximately 0.72) for predicting RD were obtained for all four of the variables evaluated after nCRT. Considering the presence of visually detectable uptake (higher than the background level) at the primary tumor site after nCRT as a positive result, we achieved a sensitivity of 94% and a specificity of 48% for the detection of RD. Conclusion: The use of 18F-FDG-PET/CT can facilitate the detection of RD after nCRT in patients with esophageal cancer.

Abstract: Introduction: Acute myocardial infarction has a high prevalence and possibility of death if timely care is not given. It is possible that treatment could be delayed during a health crisis such as the COVID-19 pandemic. Objective: The objective of this study was to evaluate the impact of the COVID-19 pandemic on the function of the infarction code in the High Specialty Medical Unit of our institution. The medical indicators of acute coronary ischemic syndrome with ST-segment elevation were compared at two times: before the COVID-19 pandemic and during it. Material and methods: An ambispective, analytical, comparative cohort study was conducted, comparing the periods of February-September 2019 and February-September 2020, in the High Specialty Medical Unit, Centro Médico del Bajío number 1, Instituto Mexicano del Seguro Social, Leon, Guanajuato, Mexico. All patients older than 18 years with clinical, electrocardiographic, and enzymatic data of acute coronary ischemic syndrome, accepted in the medical network as infarction code registered in the National Registry of Acute Coronary Ischemic Syndromes (RENASCA) electronic case report form were included in the study. Results: The independent samples t-test was used to determine the impact of the infarction code initiative based on the reperfusion therapies performed, the door-to-needle, the door-to-balloon time, and the ischemia time. There was a significant difference in the reperfusion strategy, with greater thrombolysis during the COVID-19 pandemic (57.4% versus 72.6%, odds ratio [OR] 1.97, 95% confidence interval [CI] 0.49-0.82, p < 0.001), as well as reperfusion criteria (21.03% versus 35.37%, OR 2.05, 95% CI 0.53-0.80, p < 0.0001). Mortality was not different between the time periods. Conclusions: The COVID-19 pandemic has not impacted operation of the infarction code in the High Specialty Medical Unit Centro Médico del Bajío number 1 because the medical indicators of acute coronary ischemic syndrome with ST-segment elevation did not change.

Resumo Fundamentos A cardiomiopatia hipertrófica (CMH) pode causar obstrução da via de saída do ventrículo esquerdo (VSVE) e ser responsável pelo surgimento de sintomas limitantes, como cansaço físico. Quando tais sintomas são refratários ao tratamento farmacológico, os tratamentos alternativos intervencionistas podem ser úteis, como a ablação septal por meio da infusão de álcool na artéria coronária ou por meio da miectomia cirúrgica. Recentemente, o uso de cateter de radiofrequência (RF) para ablação do septo endocárdico guiado por mapeamento eletroanatômico mostrou-se eficaz apesar da elevada incidência de bloqueio atrioventricular total. Uma alternativa seria a aplicação de radiofrequência no ponto de início do gradiente septal guiada pelo ecocardiograma transesofágico (ETE). O ecocardiograma é um método de imagem com elevada acurácia para determinação da anatomia septal. Objetivo Avaliar o efeito em longo prazo da ablação septal para alívio do gradiente ventrículo-arterial, utilizando o ETE para auxiliar no posicionamento do cateter na área de maior obstrução septal. Avaliar também os efeitos da ablação na classe funcional e parâmetros ecocardiográficos. Métodos Doze pacientes sintomáticos com obstrução da VSVE, refratários à terapia farmacológica, foram submetidos à ablação endocárdica septal com cateteres com ponta de 8 mm, cujo posicionamento foi orientado na região de maior obstrução com auxílio do ETE. Foram realizadas aplicações de radiofrequência (RF) termocontrolada e escalonadas sobre a área alvo. Após cada aplicação, o gradiente era reavaliado e nova aplicação era realizada de acordo com critério clínico. Foram avaliados os efeitos das aplicações de RF tanto para o gradiente em repouso como para o provocado por meio da manobra de Valsalva, e considerado o gradiente. As diferenças foram significativas quando o valor de p foi menor ou igual a 0,05. Resultados Observou-se que a redução da média dos gradientes máximos obtidos foi de 96,8±34,7 mmHg para 62,7±25,4 mmHg ao final de três meses do procedimento (p=0,0036). Após um ano, a média dos gradientes máximos obtidos foi de 36,1±23,8 mmHg (p=0,0001). O procedimento foi bem tolerado e não houve registro de bloqueio atrioventricular total e nem complicações graves. Conclusão A ablação septal guiada pelo ETE foi eficaz e segura, com resultados mantidos durante o período de seguimento clínico. É uma opção razoável para o tratamento intervencionista da obstrução da VSVE em CMH.

Abstract Background Hypertrophic cardiomyopathy (HCM) can cause obstruction in the left ventricular outflow tract (LVOT), and be responsible for the onset of limiting symptoms, such as tiredness. When such symptoms are refractory to pharmacological treatment, interventionist alternative therapies can be useful, such as septal ablation through the infusion of alcohol in the coronary artery or through myectomy. Recently, the use of a radiofrequency (RF) catheter for endocardial septal ablation guided by electroanatomic mapping has proven to be efficient, despite the high incidence of complete atrioventricular block. An alternative would be the application of RF at the beginning point of the septal gradient guided by the transesophageal echocardiography (TEE). The echocardiography is an imaging method with high accuracy to determine septal anatomy. Objective To assess the long term effect of septal ablation for the relief of ventricular-arterial gradient, using TEE to help place the catheter in the area of larger septal obstruction. Besides, to assess the effects of ablation on the functional class and echocardiographic parameters. Methods Twelve asymptomatic patients, with LVOT obstruction, refractory to pharmacological therapy, underwent endocardial septal ablation with 8mm-tip catheters, whose placement was oriented in the region of larger obstruction, assisted by the TEE. Temperature-controlled and staggered RF applications were performed. After each application, the gradient was reassessed and a new application was performed according to the clinical criterion. The effects of RF applications were assessed both for the gradient at rest and for that provoked by the Valsalva maneuver, and considering the gradient. The differences were significant when p-value was lower than or equal to 0.05. Results It was possible to observe that the mean reduction of the maximum gradients was from 96.8±34.7 mmHg to 62.7±25.4 mmHg three months after the procedure (p=0.0036). After one year, the mean of maximum gradient was 36.1±23.8 mmHg (p=0.0001). The procedure was well tolerated, without records of complete atrioventricular block nor severe complications. Conclusion The TEE-guided septal ablation was efficient and safe, and the results were maintained during the clinical follow-up period. It is a reasonable option for the interventionist treatment of LVOT obstruction in HCM.

ABSTRACT The unsustainable use of natural resources has contributed to the deterioration of ecosystems, loss of biodiversity, and degradation of soils in Mexico. In the state of Tabasco, environmental deterioration is evident in the chemical and physical degradation of soils. In this context, geomorphological mapping can contribute to mitigate this problem by generating a geospatial framework for land use planning, and to provide guidance for the use and management of natural resources. However, this information on a micro-regional level is scarce. The aim of this work was to generate a detailed mapping of landforms in plains and hills with agricultural use in the municipality of Huimanguillo, Tabasco, in an area of 29 398 ha. The first phase of the geopedological approach was applied and we generated maps of geomorphological landscapes, relief/modeling, lithology/facies, and landforms performing a morphographic and morphometric attributes analysis. The analysis was complemented with photointerpretation of orthophotomaps and field verification. Forty-nine percent of the study area corresponds to the geomorphologic landscape of plains, containing floodplain reliefs and depressions over alluvial sediments, with the prevalent landforms of river levee, overflow mantle, and decantation basin. These have good surface drainage, except for the basins that stay flooded for six months. The remaining area belongs to the geomorphological landscape of hills, with hillocks and depression reliefs over detritic sediments, with dominant landforms of backslope, summit, inter-hill depression, and foot slope. New landforms were zoned as inter-hill depression, teardrop, shoulder, and oil well. Depressions in elevated topographic positions stand out for having flooded wetlands for up to eight months. The study provides information that can contribute to the planning of agricultural and forestry land uses, in order to mitigate the degradation of natural resources in tropical plains and hills.

RESUMEN El uso no sustentable de los recursos naturales ha contribuido al deterioro de los ecosistemas, a la pérdida de biodiversidad, y a la degradación de suelos en México. En Tabasco, el deterioro ambiental es evidente por la degradación química y física de suelos. En este contexto, la cartografía geomorfológica contribuye a mitigar la problemática al generar un marco geoespacial para la ordenación del territorio, y así orientar el uso y manejo de los recursos naturales. Sin embargo, esta información a nivel microrregional es escasa. El objetivo del trabajo fue generar cartografía detallada de las formas del terreno en planicies y lomeríos con uso agropecuario en el municipio de Huimanguillo, Tabasco, en una superficie de 29 398 ha. Se aplicó la primera fase del enfoque geopedológico y se generó cartografía de paisajes geomorfológicos, relieve/modelados, litología/facies y formas de terreno, mediante el análisis de atributos morfográficos y morfométricos, que se complementa con la fotointerpretación de ortofotomapas y verificación de campo. El 49 % del área de estudio corresponde al paisaje geomorfológico de planicie, contiene relieves de llanura de inundación y depresiones sobre sedimentos aluviales, prevalecen las formas del terreno albardón del río, napa de desborde y cubeta de decantación; tienen buen drenaje superficial, excepto las cubetas que se inundan seis meses. El área restante corresponde al paisaje geomorfológico de lomerío, con relieves de loma y depresión sobre sedimentos detríticos; dominan las formas de ladera, cumbre, depresión interloma y pie de vertiente. Se zonificaron nuevas formas del terreno como depresión interloma, gota de lágrima, hombro y pozo petrolero; sobresalen las depresiones en posiciones topográficas elevadas, por contener humedales inundados hasta ocho meses. El estudio aporta información que puede contribuir al ordenamiento de los usos agropecuarios y forestales, para mitigar la degradación de los recursos naturales en planicies y lomeríos tropicales.

ABSTRACT BACKGROUND: The role of transient obstructive cholestasis on liver histology remains undetermined. OBJECTIVE: To investigate whether transient cholestasis impairs liver histology. DESIGN AND SETTING: Cross-sectional study at a public university hospital (UNICAMP), Brazil. METHODS: 169 individuals undergoing cholecystectomy, with or without cholestasis. were enrolled. Histopathological findings were correlated with clinical and biochemical characteristics. RESULTS: Biliary hepatopathy was more frequent in individuals with resolved cholestasis than in those with active obstruction or no jaundice (P < 0.01), as also were fibrosis and ductular proliferation (P = 0.02). Cholestasis was commoner in individuals with resolved obstruction than in those with no history (P < 0.01) or active cholestasis (P < 0.05). Biliary hepatopathy was associated with longer duration of cholestasis (P < 0.001) and higher bilirubin levels (P = 0.02) in individuals with active obstruction; with lower body mass index (P = 0.02) and longer cholestasis (P < 0.001) in individuals with resolved obstruction; and with longer cholestasis (P < 0.001) and longer interval between endoscopic retrograde cholangiopancreatography and surgery (P = 0.03) overall. In individuals with active obstruction, duration of cholestasis (R = 0.7; P < 0.001) and bilirubin levels (R = 0.6; P = 0.004) were independently correlated with cholestasis severity. Duration of cholestasis (R = 0.7; P < 0.001) was independently correlated with ductular proliferation severity. CONCLUSIONS: Transient cholestasis was associated with significant histopathological changes, even after its resolution. Longer duration of obstruction correlated with greater severity of histopathological changes, especially cholestasis and ductular proliferation. This emphasizes the need for early treatment of obstructive cholestasis.

ABSTRACT We conducted an experiment to evaluate the effect of a polyherbal additive with metabolites such as antioxidants, vitamins, and small hydrolysable tannoids oils on productive parameters and blood metabolites in finishing lambs. Forty male Hampshire × Suffolk lambs (23.79±2.24 kg) were used in a completely randomized experimental design. Treatments consisted of dietary inclusion of a polyherbal additive based on Emblica officinalis and Ocimum sanctum at 0, 5, 10, and 15 g/kg dry matter for 60 d. There were no effects on daily gain, dry matter intake, feed conversion, back fat thickness, and Longissimus dorsi area; however, hot carcass dressing improved linearly as the level of herbal additive supplementation was increased. The antioxidants of the polyherbal additive linearly inhibited lipid oxidation of the meat (24 h; day 10) and improved its water-holding capacity (24 h). Meat lightness after 1 d was reduced linearly, but no changes were detected in other color parameters. Metabolites (glucose, urea, cholesterol) related to energy or protein metabolism were not affected by the herbal additive. Lymphocytes and basophiles were reduced linearly whereas monocytes and segmented neutrophils increased linearly for polyherbal additive. The inclusion of the polyherbal additive does not improve daily gain or feed efficiency in finishing lambs but improves the carcass dressing and antioxidant capacity of the meat.

RESUMO Histórico e objetivos: a associação entre a doença hepática gordurosa não alcoólica (DHGNA) e o adenocarcinoma ductal pancreático (ACDP) foi sugerida anteriormente. Este estudo visa investigar esta associação e identificar possíveis ligações entre as variáveis do espectro da DHGNA e o ACDP. Métodos: foi realizado estudo transversal caso-controle analítico e comparativo para analisar pacientes submetidos a ressecção cirúrgica de ACDP e compará-los a grupo controle de indivíduos submetidos a colecistectomia em hospital público terciário de ensino, pareados por sexo, idade e IMC. Os exames histopatológicos hepáticos foram comparados entre casos e controles. Resultados: dos 56 indivíduos, 36 eram do sexo masculino (64,3%) e a idade mediana era de 61,5 anos de idade (intervalo interquartil 57,5-70). A mediana do IMC dos participantes foi de 24,3 kg/m2 (intervalo interquartil 22,1 26,2). Esteatose microvesicular (p = 0,04), balonização hepatocelular (p = 0,02), fibrose (p = 0,0003) e esteato-hepatite (p = 0,03) foram significativamente mais frequentes no grupo de casos. As razões de chances para balonização hepatocelular (6,2; IC 95%: 1,2 - 31,8; p = 0,03), fibrose (9,3; IC 95%: 2,5 - 34,1; p = 0,0008) e esteato-hepatite (3,9; IC 95%: 1,1 - 14,3; p = 0,04) foram estatisticamente significativas em relação à prevalência de ACDP. Conclusões: houve associações significativas entre aspectos histopatológicos de DHGNA (esteatose microvesicular, balonização hepatocelular, fibrose e esteato-hepatite) e a ocorrência de ACDP.

ABSTRACT Background and Aims: An association between non-alcoholic fatty liver disease (NAFLD) and pancreatic ductal adenocarcinoma (PDAC) has been previously suggested. This study aims at investigating this association and at identifying potential links between variables of the NAFLD spectrum and PDAC. Methods: A cross-sectional case-matched analytical and comparative study was carried out to analyze patients undergoing surgical resection of PDAC and compare them to a control group of individuals undergoing cholecystectomy at a public tertiary teaching hospital, matched by sex, age and BMI. Hepatic histopathological examinations were compared between cases and controls. Results: Of 56 individuals, 36 were male (64.3%) and the median age was 61.5 years old (interquartile range: 57.5 - 70). The participants’ median BMI was 24.3 kg/m2 (interquartile range: 22.1-26.2 kg/m2). Microvesicular steatosis (p=0.04), hepatocellular ballooning (p=0.02), fibrosis (p=0.0003) and steatohepatitis (p=0.03) were significantly more frequent in the group of cases. Odds ratios for hepatocellular ballooning (6.2; 95%CI: 1.2-31.8; p=0.03), fibrosis (9.3; 95%CI: 2.5-34.1; p=0.0008) and steatohepatitis (3.9; 95%CI: 1.1-14.3; p=0.04) were statistically significant in relation to the PDAC prevalence. Conclusions: Significant associations were identified between histopathological aspects of NAFLD (microvesicular steatosis, hepatocellular ballooning, fibrosis, and steatohepatitis) and PDAC.

SUMMARY: Sexual dimorphism is one of the most important ways to identify bone remains in mass disasters. Many of them have been used for this purpose; mainly skull, pelvis and long bones. However, only a few studies using the patella have been done and, to our knowledge, there are no assessments of previous results in the literature. Meta-analysis provides a useful strong tool to test, in a systematic way, the most relevant information about a given research field. The aim of this study is to apply the meta-analytic technique to assess the major studies concerning sexual dimorphism in the patella by measuring classical metric traits: maximum height and maximum width, with different techniques, such as caliper, radiography, tomography and magnetic resonance. The 17 papers found, involving a total sample size higher than 2600 patellae, showed a very high heterogeneity- around 93 % of I2 value, for height and width measurements when all the studies were analyzed together. Homogeneity increased when each study was classified according to the techniques used. In this case, a statistical difference appeared, among the several subgroups of techniques for the two measurements, suggesting the importance of the methodology used. Maximum height and maximum width were all showed to be statistically relevant in distinguishing both sexes.

RESUMEN: El dimorfismo sexual es una de las formas más importantes para identificar restos óseos en desastres masivos. Se han utilizado huesos como cráneo, pelvis y huesos largos para la diferenciación sexual. Sin embargo, solo se han realizado unos pocos estudios con la patela y, hasta donde sabemos, no hay evaluaciones de resultados anteriores en la literatura. El meta-análisis proporciona una herramienta sólida y útil para probar, de manera sistemática, la información más relevante sobre un cierto campo de investigación. El objetivo de este estudio consiste en aplicar la técnica metaanalítica para evaluar los principales estudios sobre dimorfismo sexual en la patela midiendo los rasgos métricos clásicos: altura máxima y anchura máxima, con diferentes técnicas: calibre, radiografía, tomografía y resonancia magnética. Los 17 de documentos encontrados, con un tamaño de muestra total superior a 2600 patelas, mostraron una heterogeneidad muy alta, alrededor del 93 % del valor de I2, para mediciones de altura y anchura cuando todos los estudios se analizaron juntos. La homogeneidad aumentó cuando cada estudio se clasificó de acuerdo con las técnicas utilizadas. En este caso, se observó diferencias estadísticas, entre los subgrupos de técnicas para las dos mediciones, lo que sugiere la importancia de la metodología utilizada. La altura máxima y la anchura máxima mostraron ser estadísticamente relevantes para distinguir ambos sexos.
