Abstract INTRODUCTIONSARS-CoV-2 infection can produce endothelial injury and microvascular damage, one cause of the multiorgan failure associated with COVID-19. Cerebrovascular endothelial damage increases the risk of stroke in COVID-19 patients, which makes prompt diagnosis important. Endothelial dysfunction can be evaluated by using transcranial Doppler ultrasound to study cerebral hemodynamic reserve, but there are few of these studies in patients with COVID-19, and the technique is not included in COVID-19 action and follow-up guidelines nationally or internationally. OBJECTIVEEstimate baseline cerebral hemodynamic patterns, cerebral hemodynamic reserve, and breath-holding index in recovered COVID-19 patients. METHODWe conducted an exploratory study in 51 people; 27 men and 24 women 20–78 years of age, divided into two groups. One group comprised 25 recovered COVID-19 patients, following clinical and epidemiological discharge, who suffered differing degrees of disease severity, and who had no neurological symptoms or disease at the time they were incorporated into the study. The second group comprised 26 people who had not been diagnosed with COVID-19 and who tested negative by RT-PCR at the time of study enrollment. Recovered patients were further divided into two groups: those who had been asymptomatic or had mild disease, and those who had severe or critical disease. We performed transcranial Doppler ultrasounds to obtain baseline and post-apnea tests of cerebral hemodynamic patterns to evaluate cerebral hemodynamic reserve and breath-holding indices. We characterized the recovered patient group and the control group through simple descriptive statistics (means and standard deviations). RESULTSThere were no measurable differences in baseline cerebral hemodynamics between the groups. However, cerebral hemodynamic reserve and breath-holding index were lower in those who had COVID-19 than among control participants (19.9% vs. 36.8% and 0.7 vs. 1.2 respectively). These variables were similar for patients who had asymptomatic or mild disease (19.9% vs.19.8%) and for those who had severe or critical disease (0.7 vs. 0.7). CONCLUSIONSPatients recovered from SARS-CoV-2 infection showed decreased cerebral hemodynamic reserve and breath-holding index regardless of the disease’s clinical severity or presence of neurological symptoms. These abnormalities may be associated with endothelial damage caused by COVID-19. It would be useful to include transcranial Doppler ultrasound in evaluation and follow-up protocols for patients with COVID-19.

RESUMO A poluição do ar ambiental é um dos principais fatores de risco de morbidade e mortalidade global. Ela tem impacto direto na saúde humana, sendo responsável pelo aumento de incidência e de óbitos por doenças cardiorrespiratórias, neoplásicas e metabólicas; também contribui para o aquecimento global e para as consequentes alterações do clima associadas a eventos extremos e aos desequilíbrios ambientais. Nesta revisão, apresentamos artigos que evidenciam o impacto da exposição a diferentes fontes e tipos de poluentes do ar no sistema respiratório; apresentamos os efeitos agudos — como aumento de sintomas e no número de atendimentos em serviços de emergência, internações e óbitos — e crônicos — como o aumento da incidência de asma, DPOC e câncer de pulmão, assim como o declínio acelerado da função pulmonar. Também são apresentados e discutidos os efeitos da poluição atmosférica em populações mais suscetíveis e dos efeitos associados à realização de exercícios físicos em ambientes poluídos. Por fim, apresentamos os principais estudos brasileiros sobre o assunto. Os serviços de atenção à saúde e de prevenção de doenças devem ficar atentos a esse importante fator de risco para orientar indivíduos mais suscetíveis sobre medidas de proteção que possam facilitar seu tratamento, além de estimular a adoção de medidas ambientais que contribuam para a redução dessas emissões.

ABSTRACT Environmental air pollution is a major risk factor for morbidity and mortality worldwide. Environmental air pollution has a direct impact on human health, being responsible for an increase in the incidence of and number of deaths due to cardiopulmonary, neoplastic, and metabolic diseases; it also contributes to global warming and the consequent climate change associated with extreme events and environmental imbalances. In this review, we present articles that show the impact that exposure to different sources and types of air pollutants has on the respiratory system; we present the acute effects—such as increases in symptoms and in the number of emergency room visits, hospitalizations, and deaths—and the chronic effects—such as increases in the incidence of asthma, COPD, and lung cancer, as well as a rapid decline in lung function. The effects of air pollution in more susceptible populations and the effects associated with physical exercise in polluted environments are also presented and discussed. Finally, we present the major studies on the subject conducted in Brazil. Health care and disease prevention services should be aware of this important risk factor in order to counsel more susceptible individuals about protective measures that can facilitate their treatment, as well as promoting the adoption of environmental measures that contribute to the reduction of such emissions.

Abstract Background: Colorectal cancer (CRC) is one of the main five causes of morbidity and mortality by oncologic diseases in our country and worldwide. Recently, fecal immunochemical test (FIT) has proven to be a noninvasive screening test that allows to select patients most likely to have a pre-malign lesion in order to perform a colonoscopy. Objective: To report the findings of a CRC screening program using FIT in our country population. Method: A multicentric study was performed, by inviting open population older than 50 years to participate in a CRC screening. Quantitative FIT specific for human hemoglobin was used, with a cut point of 100 ng/ml or higher to consider as positive. Those patients with positive results were asked to undergo a colonoscopy. In the cases where polypoid lesions were found, biopsies were performed. Results: In total, 751 FIT were processed, and 51 (6.8) of those were positive, with a rate of 15.9 premalign lesions for 1,000 individuals, and 1.3 patients with CRC for every 1,000. Conclusions: The present study matches worldwide reports, supporting the initiative of establishing a formal and standardized CRC screening program in the public health sector.

Resumen Antecedentes: El cáncer colorrectal (CCR) es una de las cinco primeras causas de morbimortalidad por cáncer en nuestro país y en todo el mundo. La prueba inmunoquímica fecal (FIT, fecal immunochemical test) es una herramienta de tamizaje no invasiva que permite seleccionar a los sujetos con mayor probabilidad de lesión premaligna en la colonoscopia. Objetivo: Reportar los resultados del programa de escrutinio para CCR mediante FIT en población abierta en México. Método: Estudio multicéntrico nacional en población abierta mayor de 50 años a través de medios de difusión masiva para participar en un programa de escrutinio de CCR. Se utilizó FIT cuantitativa específica para detectar hemoglobina humana con un punto de corte de 100 ng/ml (prueba positiva). Se realizó colonoscopia a los positivos. Se tomaron biopsias dirigidas de las lesiones premalignas/cáncer para análisis histopatológico. Resultados: Se procesaron 751 FIT, de las cuales 51 (6.8%) fueron positivas, con una tasa de 15.9 lesiones premalignas por cada 1,000 sujetos evaluados, y 1.3 pacientes con CCR por cada 1,000 pacientes. Conclusiones: Nuestro estudio concuerda con lo reportado en la literatura mundial, apoyando así la iniciativa de fomentar el establecimiento de un tamizaje formal y estandarizado dentro del sector de salud pública.

Abstract Esophagitis dissecans (ESD) is an uncommon disease that is associated with eosinophilic esophagitis (EoE), candidiasis and/or drugs. We aim to characterize the clinical, endoscopic and histological damage of the mucosal in subjects with dysphagia, its relation to concomitant entities and the treatment response. This is a retrospective observational study in patients with dysphagia and esophageal mucosal damage We included 23 patients (mean age = 55 years) who had GERD symptoms, dysphagia and/or odynophagia. There were 10, 9 and 4 cases of esophagitis dissecans, desquamative/esfacelante (ESD/ES) and fibrostenotic, respectively. ESD/SE is a rare entity with variable clinical, endoscopic and histological spectrum. The association with GERD was frequent.

Resumo: Introdução: A cirurgia endoscópica funcional endonasal é um procedimento cirúrgico frequente entre os otorrinolaringologistas. Em 2014, a Sociedade Europeia de Rinologia publicou o "Documento Europeu para Posicionamento sobre a Terminologia Anatômica Interna do Nariz e das Cavidades Paranasais" com o objetivo de unificar os termos na língua inglesa. Ainda não dispomos de uma terminologia unificada na língua portuguesa. Objetivo: Adaptação transcultural dos termos anatômicos do nariz e das cavidades paranasais para o português da "European Anatomical Terminology of the Internal Nose and Paranasal Sinuses". Método: Um grupo de rinologistas de todo o Brasil, com experiência em cirurgia endoscópica endonasal, foi convidado a participar da elaboração desse posicionamento sobre os termos anatômicos do nariz e das cavidades paranasais para o português conforme metodologia adaptada da previamente descrita por Rudmik e Smith. Resultados: Os resultados desse documento foram gerados a partir da concordância da maioria dos participantes conforme as sugestões mais populares entre os rinologistas. Uma adaptação transcultural da terminologia anatômica nasossinusal foi consolidada. Sugerimos que se busque uniformizar termos como "concha inferior", "septo nasal", "porção (óssea/cartilaginosa) do septo nasal", "meato (médio/ inferior) nasal", "via da drenagem do seio frontal", "recesso frontal" e "processo uncinado". Conclusão: Consolidamos uma versão adaptada em português da "European Anatomical Terminology of the Internal Nose and Paranasal Sinuses" que auxiliará a publicação de comunicados técnicos, publicações científicas e o ensino dos termos anatômicos internos do nariz e das cavidades paranasais no Brasil.

Abstract Introduction: Functional endonasal endoscopic surgery is a frequent surgical procedure among otorhinolaryngologists. In 2014, the European Society of Rhinology published the "European Position Paper on the Anatomical Terminology of the Internal Nose and Paranasal Sinuses", aiming to unify the terms in the English language. We do not yet have a unified terminology in the Portuguese language. Objective: Transcultural adaptation of the anatomical terms of the nose and paranasal cavities of the "European Anatomical Terminology of the Internal Nose and Paranasal Sinuses" to Portuguese. Methods: A group of rhinologists from diverse parts of Brazil, all experienced in endoscopic endonasal surgery, was invited to participate in the creation of this position paper on the anatomical terms of the nose and paranasal sinuses in the Portuguese language according to the methodology adapted from that previously described by Rudmik and Smith. Results: The results of this document were generated based on the agreement of the majority of the participants according to the most popular suggestions among the rhinologists. A cross-cultural adaptation of the sinonasal anatomical terminology was consolidated. We suggest the terms "inferior turbinate", "nasal septum", "(bone/cartilaginous) part of the nasal septum", "(middle/inferior) nasal meatus", "frontal sinus drainage pathway", "frontal recess" and "uncinate process" be standardized. Conclusion: We have consolidated a Portuguese version of the European Anatomical Terminology of the Internal Nose and Paranasal Sinuses, which will help in the publication of technical announcements, scientific publications and the teaching of the internal anatomical terms of the nose and paranasal sinuses in Brazil.

Introduction: Non-medical staff members in hospitals are highly credible at population level, and are a source of opinion even though they do not have sufficient medical training. Objectives: To analyse the attitudes of non-medical professionals of Spanish and Latin American hospitals towards organ donation and identify the factors that influence these attitudes. Material and method: Through the "Proyecto Colaborativo Internacional Donante" (International Collaborative Donor Project), a stratified random sample was selected from non-medical services of eleven hospitals: 3 Spanish (n=277), 5 Mexican (n=632), 2 Cuban (n=42) and 1 Costa Rican (n=101). Results: Of the 1052 professionals surveyed, 72% (n=754) were in favour of donating an organ after death. By country, 98% of Cubans, 80% of Mexicans, 66% of Costa Ricans and 52% of Spanish were in favour (P<.001). The most influential variables were: 1) country, with results being more positive in Mexico (odds ratio [OR]=2.197), 2) believing in the possibility that they will require a transplant (OR=2.202), 3) having discussed the issue with their family (OR=3.23), 4) the positive attitude of their partner towards donation (OR=3.322), 5) not being concerned about possible mutilation of their body after donation (OR=3.378), 6) preferring options other than burial (OR=2.525), 7) accepting an autopsy (OR=2.958). Conclusions: The attitude of non-medical staff members of hospitals towards the donation of their own organs varies greatly depending on the country of the respondent. Psychosocial factors that influence these attitudes are similar to those described at the population level.

Introducción: El personal no sanitario de centros hospitalarios tiene una importante credibilidad a nivel poblacional, siendo un grupo generador de opinión sin formación sanitaria adecuada. Objetivo: Analizar la actitud hacia la donación de los órganos de los profesionales no sanitarios de hospitales españoles y latinoamericanos, y determinar los factores que condicionan dicha actitud. Material y métodos: Del Proyecto Colaborativo Internacional Donante se selecciona una muestra aleatoria y estratificada entre los servicios no sanitarios de once hospitales: 3 españoles (n = 277), 5 mexicanos (n = 632), 2 cubanos (n = 42) y 1 costarricense (n = 101). Resultados: De los 1052 profesionales encuestados, el 72 % (n = 754) está a favor de la donación de órganos tras fallecer. Por país, el 98 % de los cubanos están a favor, el 80 % de los mexicanos, el 66 % de los costarricenses y el 52 % de los españoles (p < 0,001). Las variables con más peso son: 1) país, siendo más favorable en México (odds ratio [OR] = 2,197); 2) creer en la posibilidad de necesitar un trasplante (OR = 2,202); 3) haber comentado el tema con la familia (OR = 3,23); 4) actitud favorable de la pareja hacia la donación (OR = 3,322); 5) no estar preocupado por la posible mutilación del cuerpo tras la donación (OR = 3,378); 6) preferir otras opciones distintas de la inhumación (OR = 2,525); 7) aceptar la realización de una autopsia (OR = 2,958). Conclusiones: La actitud hacia la donación de órganos propios entre el personal no sanitario de centros hospitalarios presenta variaciones importantes según el país del encuestado. Los factores psicosociales que condicionan dicha actitud son similares a los descritos a nivel poblacional.

O objetivo deste estudo foi analisar os dados de endoscopia e sintomas de 118 pacientes mexicanos com síndrome do intestino irritável (IBS), dispepsia, doença do refluxo não-erosiva (NERD) e esofagite erosiva (EE). Os pacientes com IBS preencheram os critérios para dispepsia em 47%, para NERD em 48%, e para pacientes EE em 48% dos casos. Esofagite estava presente em 42% dos pacientes com IBS e em 45% dos pacientes com dispepsia. A maior prevalência de hérnia de hiato foi encontrada na EE em comparação com NERD. Azia e eructação ácida foram associadas à presença de esofagite; eructação ácida, regurgitação e dor noturna, com duodenite; e azia e regurgitação com hérnia de hiato. Os homens relataram mais frequentemente sintomas como muco nas fezes, distensão abdominal, náuseas e gastrite, enquanto que as mulheres mais frequentemente relataram esofagite e duodenite. Os pacientes com NERD (OR 2,54, IC 95% 1,08-5,99, p = 0,04), apresentaram tenesmo e saciedade precoce, e os homens tiveram um risco aumentado relacionado a fezes endurecidas ou fragmentadas. Em conclusão, quase metade dos pacientes mexicanos com NERD, EE e dispepsia preenchem os critérios para a IBS. Um grande número de sintomas foi correlacionado com a endoscopia, esta correlação pode ser utilizada para aumentar a indicação da endoscopia e sua aplicação em estudos clínicos.

The aim of this study was to analyze the data of endoscopy and symptoms in 118 Mexican patients with irritable bowel syndrome (IBS), dyspepsia, non-erosive reflux disease (NERD) and erosive esophagitis (EE). IBS criteria were fulfilling for dyspepsia patients in 47%, for NERD in 48%, and for EE patients in 48% of cases. Esophagitis was present in 42% of patients with IBS and in 45% of patients with dyspepsia. A higher prevalence of hiatus hernia was found in EE vs. NERD. Heartburn and acid eructation were associated with the presence of esophagitis; acid eructation, regurgitation and nocturnal pain with duodenitis; and heartburn and regurgitation with hiatus hernia. Males more frequently reported: ucus in feces, abdoinal distension, nausea and gastritis; and oen ore frequently reported esophagitis and duodenitis. Patients with NERD (OR 2.54, 95% CI 1.08 to 5.99, p=0.04), tenesmus and early satiety, and men had an increase risk for reporting hard or lumpy stools. In conclusion, nearly half of the Mexican patients with NERD, EE and dyspepsia fulfill criteria for IBS. A large number of symptoms were correlated with endoscopy, which can be used to improve the indication of the endoscopy and its implementation in clinical studies.
