ABSTRACT Asbestos was largely used in Brazil. It is a mineral that induces pleural and pulmonary fibrosis, and it is a potent carcinogen. Our objective was to develop recommendations for the performance of adequate imaging tests for screening asbestos-related diseases. We searched peer-reviewed publications, national and international technical documents, and specialists’ opinions on the theme. Based on that, the major recommendations are: Individuals exposed to asbestos at the workplace for ≥ 1 year or those with a history of environmental exposure for at least 5 years, all of those with a latency period > 20 years from the date of initial exposure, should initially undego HRCT of the chest for investigation. Individuals with pleural disease and/or asbestosis should be considered for regular lung cancer monitoring. Risk calculators should be adopted for lung cancer screening, with a risk estimate of 1.5%. Brazil fibrosis carcinogen asbestosrelated related diseases peerreviewed peer reviewed publications documents specialists theme are 2 investigation andor monitoring 15 1.5% 1.5 1.

Abstract Objective: to describe the incomplete filling out of the profession/occupation variable in the flu-like syndrome, severe acute respiratory syndrome and mortality databases in Brazil. Methods: descriptive study with secondary data from flu-like syndrome (FLS), severe acute respiratory syndrome (SARS) and mortality databases (SIM). We calculeted the absolute and relative filling frequencies of the profession/occupation variable according to State, gender, regions, and federative units, for 2020 and 2021. Results: we found a 94.7% incompleteness on the FLS database, 97.7% of missing profession/occupation data on the SARS, and 17.0% on the SIM database. Incompleteness frequency was above 91.0% in all Brazilian regions for FLS and SARS. Incompleteness on the mortality database was over 13.0%. All federative units presented incompleteness above 90.0% for FLS, 74.0% for SARS, and 6.8% for mortality in all genders. Higher levels of missing data were found in the states of Amapá for FLS (98.1%), Rio Grande do Sul for SARS and Alagoas (45.0%) for mortality (99.4%). Conclusions: all databases showed a high incompleteness of the profession/occupation variable. We recommend an articulation between the Ministry of Health, Ministry of Labor and workers’ representations to solve this lack of data on occupation/profession in public databases.

RESUMO Objetivo: A silicose é uma pneumoconiose caracterizada por fibrose do parênquima pulmonar causada por inalação de partículas de sílica. Fatores genéticos podem desempenhar um papel na gravidade da silicose. Nosso objetivo foi avaliar a influência de polimorfismos dos genes ACE, FAS, FASLG, NOS2, IL1RN, FAM13A, TGFB1 e TNF na gravidade da silicose. Métodos: Nove polimorfismos foram genotipados por meio de PCR em uma amostra composta por 143 pacientes com silicose no estado do Rio de Janeiro, Brasil. Resultados: A silicose foi classificada em simples em 57 (40%) dos pacientes e em complicada, em 86 (60%). O genótipo TT do polimorfismo rs1800469 do gene TGFB1 teve efeito protetor contra a silicose complicada (OR = 0,35; IC95%: 0,14-0,92; p = 0,028) em comparação com os outros dois genótipos (CC+CT). O alelo T polimórfico do polimorfismo rs763110 do gene FASLG (OR = 0,56; IC95%: 0,31-0,99; p = 0,047) e um modelo dominante do alelo T (TT+CT: OR = 0,37; IC95%: 0,15-0,96; p = 0,037) também tiveram efeito protetor. Quando se compararam os pacientes que tinham silicose simples com um tempo maior de exposição à sílica (> 44.229 horas) àqueles que tinham silicose complicada com um tempo menor de exposição à sílica, o alelo T do polimorfismo rs763110 do gene FASLG (OR = 0,20; IC95%: 0,08-0,48; p < 0,0001) e modelos dominantes e recessivos (OR = 0,06; IC95%: 0,00-0,49; p = 0,01 e OR = 0,22; IC95%: 0,06-0,77; p = 0,014, respectivamente) tiveram efeito protetor contra a gravidade da silicose. Conclusões: Polimorfismos rs1800469 do gene TGFB1 e polimorfismos rs763110 do gene FASLG parecem estar envolvidos na gravidade da silicose. Como há poucos estudos que tenham estabelecido relações entre polimorfismos genéticos e a gravidade da silicose, esses resultados devem ser replicados em outras populações.

ABSTRACT Objective: Silicosis is a pneumoconiosis characterized by fibrosis of the lung parenchyma caused by inhalation of silica particles. Genetic factors might play a role in the severity silicosis. We sought to evaluate the influence of polymorphisms in the ACE, FAS, FASLG, NOS2, IL1RN, FAM13A, TGFB1, and TNF genes on the severity of silicosis. Methods: Nine polymorphisms were genotyped by PCR in a sample of 143 patients with silicosis in the state of Rio de Janeiro, Brazil. Results: Fifty-seven patients (40%) were classified as having simple silicosis and 86 (60%) were classified as having complicated silicosis. The TT genotype of rs1800469 in the TGFB1 gene showed a protective effect for complicated silicosis (OR = 0.35; 95% CI, 0.14-0.92; p = 0.028) when compared with the other two genotypes (CC+CT). The polymorphic T allele of rs763110 in the FASLG gene (OR = 0.56; 95% CI, 0.31-0.99; p = 0.047), as well as a dominant model for the T allele (TT+CT: OR = 0.37; 95% CI, 0.15-0.96; p = 0.037), also showed a protective effect. When patients with simple silicosis despite having been exposed to silica for a longer time (> 44,229 hours) were compared with patients with complicated silicosis despite having been exposed to silica for a shorter time, the T allele of rs763110 in the FASLG gene (OR = 0.20; 95% CI, 0.08-0.48; p < 0.0001), as well as dominant and recessive models (OR = 0.06; 95% CI, 0.00-0.49; p = 0.01 and OR = 0.22; 95% CI, 0.06-0.77; p = 0.014, respectively), showed a protective effect against the severity of silicosis. Conclusions: It appears that rs1800469 polymorphisms in the TGFB1 gene and rs763110 polymorphisms in the FASLG gene are involved in the severity of silicosis. Given the lack of studies relating genetic polymorphisms to the severity of silicosis, these results should be replicated in other populations.

ABSTRACT OBJECTIVE To assess the perceptions of pregnant women about COVID-19 and the prevalence of common mental disorders during the implemented social distancing period. METHODS This was an observational, cross-sectional study using digital media, of pregnant women exposed to social distancing due to the COVID-19 pandemic, in Fortaleza, Ceará, Northeastern Brazil. Common mental disorders were estimated using the modified Self-Report Questionnaire-20 (SRQ-20) scale, and the feelings towards COVID-19 were assessed using the Fear of COVID-19 scale through telephone calls made in May 2020. COX multivariate regression models were used to verify the associations. RESULTS Of the 1,041 pregnant women, 45.7% (95%CI: 42.7–48.8) had common mental disorders (CMD). All items of the Fear of COVID-19 Scale showed a significant association with the prevalence of CMD (p < 0.001). A CMD risk gradient was observed, going from a prevalence ratio of 1.52 (95%CI: 1.13–2.04) in pregnant women with two positive items to 2.70 (95%CI: 2.08–3.51) for those with four positive items. Early gestational age and the lack of prenatal care were also associated with CMD. CONCLUSIONS The prevalence of common mental disorders in pregnant women was high during the period of social distancing and was aggravated by negative feelings towards COVID-19.

Abstract Purpose: To evaluate the contribution of ursodeoxycholic acid (UDCA) in the first 12 months after Roux-en-Y gastric bypass in the prevention of gallstone formation. Methods: A community-based clinical trial was conducted. A total of 137 patients were included in the study; 69 were treated with UDCA, starting 30 days after the surgery, at a dose of 150 mg twice daily (300 mg/day) over a period of 5 consecutive months (GROUP A), and 68 were control patients (GROUP B). The patients were followed-up, and ultrasonography was performed to determine the presence of gallstones at various times during follow-up. Demographic, anthropometric and comorbid indicators were obtained. The data were subjected to normality tests and evaluated using appropriate tests. Results: Patients did not differ in their baseline characteristics. Of the 69 patients who used UDCA, only one patient developed cholelithiasis (1%), whereas 18 controls (26%) formed gallstones (OR = 24.4, p <0.001). Also, other factors were found not to influence the formation of calculi, such as pre-operative or postoperative hepatic steatosis or diabetes (p = 0.759, 0.468, 0.956). Conclusion: The results demonstrated that patients who did not use UDCA showed a 24.4-fold greater probability of developing cholelithiasis.

Resumo Introdução Este estudo avaliou alterações respiratórias, auditivas e citogenéticas em trabalhadores de um estaleiro em Angra dos Reis, no Estado do Rio de Janeiro, relacionadas à exposição de pintores a solventes, metais e ruído no ambiente de trabalho. Métodos Foram avaliados função pulmonar, perdas auditivas e índice de reconhecimento da fala, e alterações citogenéticas pelo teste de aberrações cromossômicas. Foram avaliados manganês e chumbo em sangue por espectrometria de absorção atômica. Os indicadores de efeito utilizados para chumbo foram ALAD e ALA-U, determinados por espectrofotometria e cromatografia líquida, respectivamente. Resultados Seis dos 9 trabalhadores avaliados apresentaram alteração funcional respiratória. Quase 70% dos 18 trabalhadores avaliados apresentaram audição reduzida, com associação entre PAIR e chumbo em sangue. O percentual médio de recuperação da ALAD foi de 32,9%, com médias de ALA-U de 1,7 mg g-1 creatinina, 4,65 µg dL-1 para Pb-S e 10 µg L -1 para Mn-S entre os trabalhadores. Foram observadas associações entre ALA-D ativada com Mn-S e com a presença de aberrações cromossômicas. As alterações citogenéticas identificadas foram aneuploidias, separação prematura centromérica e aberrações como formação de anéis, quebras e união de cromátides irmãs. Conclusão os trabalhadores do estaleiro apresentam alterações que podem ser associadas à exposição ocupacional.

Abstract Introduction This study evaluated respiratory, audiological and cytogenetic alterations in shipyard workers in Angra dos Reis, state of Rio de Janeiro/Brazil, and their correlation to the occupational exposure of painters to solvents, metals and noise present. Methods We evaluated pulmonary function, hearing loss and speech recognition, as well as cytogenetic alterations. Indicators of exposure to lead and manganese in blood were evaluated by atomic absorption spectrometry. The determination of ALAD and ALA-U was performed by spectrophotometry and liquid chromatography, respectively. Results Six of the 9 workers evaluated for lung function had respiratory functional impairment. Almost 70% of the 18 evaluated workers had reduced hearing, with association between PAIR and values of lead in blood. The average percentage of recovery of ALAD was 32.9%; average was 1.7 mg g-1 creatinine for ALA-U, 4.65 µg dL-1 for Pb-B and 10 µg L-1 for Mn-B. We observed associations between activated ALA-D with Mn-B and the presence of chromosomal aberrations. Furthermore, we identified cytogenetic alterations as aneuploidy, premature centromere separation; as well as ring formation, breakage, and sister chromatid union. Conclusion Shipyard workers presented alterations that can be associated with occupational exposure.
