Background Due to social and geographical isolation, indigenous people are more vulnerable to adverse conditions; however, there is a lack of data on the epidemics’ impact on these populations. Thus, this article’s objective was to describe the epidemiological situation of COVID-19 in indigenous communities in Brazil. Methods This descriptive observational study was carried out in indigenous communities in the municipality of Amaturá (Amazonas, Brazil). Individuals from the Alto Rio Solimões Special Indigenous Sanitary District (DSEI) who met the Sars-Cov-2 infection case definitions during the period between January and August 2020 were included. For case notification, the definitions adopted by the Ministry of Health of Brazil and by the Special Secretariat for Indigenous Health were considered. Results Out of the entire population served by the Alto Rio Solimões DSEI ( n = 2890), 109 indigenous people were suspected of having been infected with Sars-Cov-R during the study period; a total of 89 cases were actually confirmed (rate: 3.08 cases/100,000 inhabitants). Most patients diagnosed with COVID-19 were female (56.2%), with a mean age of 32.4 (± 23.6) years. Predominant symptoms were fever (76.4%), dry cough (64%), and headache (60.7%). Complications occurred in 7.9% of the patients; no deaths were reported. Conclusion These results enhance the observation that indigenous populations, even if relatively isolated, are exposed to COVID-19. The disease cases assessed showed a favorable evolution, which does not mean reducing the need for caring of this population.

Objective: To evaluate the distribution of cases of congenital anomalies in the state of Santa Catarina by health macro-region, to determine the frequency according to maternal and neonatal variables, to estimate the related mortality, and the trends in the period 2010–2018. Methods: An ecological time-series study with secondary data on congenital anomalies and the sociodemographic and health variables of mothers and newborns living in Santa Catarina, from 2010 to 2018. For temporal trend analysis, generalized linear regression was performed using the Prais-Winsten method with robust variance. Results: The average prevalence of congenital anomalies in the period was 8.9 cases per 1,000 live births, being 9.4 cases by 1,000 live births in 2010 and, in 2018, 8.2/1,000. The trend remained stable in the analyzed period. The major malformations were musculoskeletal, hip, and foot malformations, with a proportion ≥30%. There was a higher prevalence of congenital anomalies in low birthweight, preterm, male livebirths with Apgar≤7, born by cesarean section, mothers of older age (≥40 years), and less educated (less than eight years of study). Infant mortality due to congenital malformations was 2.6 deaths/1,000 live births, representing about 25.8% of the total infant deaths in the period. Conclusions: The frequency of congenital anomalies and the mortality with anomalies was stable in the studied period in Santa Catarina. The presence of anomalies was associated with low birth weight, prematurity, and low Apgar score. The highest proportion of congenital anomalies was in the musculoskeletal system.

Objective: To carry out a cross-cultural adaptation and validation of the Child Oral Health Impact Profile-COHIP-SF 19 to be used in Brazil. Material and Methods: The adaptation process followed five stages: translation into Portuguese, synthesis of different translations, back-translation, expert panel analysis, and pre-final version testing. The final version was administered at two different moments to a sample of 100 schoolchildren aged 8-15 years in Criciúma, Brazil. The Brazilian version of the Child Perceptions Questionnaire (CPQ11-14) was administered as a comparison parameter. In both administrations of the questionnaire, factor analysis, principal component extraction, and factor rotation were performed. The internal validation was performed by using the α-Cronbach coefficient and the congruence coefficient between the rotated factors in the two administrations of the questionnaire. In order to analyze the external validity, the factors of the first administration of COHIP-SF 19 and CPQ11-14 factors were compared by using simple linear regression analysis and congruence coefficient. Results: A Brazilian version of the questionnaire was obtained. The results of the internal validity analysis indicated adequate internal consistency and statistically significant internal congruence in the two factors identified in the factorial analysis. The linear regression analysis between the COHIP-SF 19 and CPQ11-14 showed weak correlations, and the congruence indices were not statistically significant. Conclusion: The Brazilian version of COHIP-SF 19 showed good internal consistency, but lacked external validity when compared to CPQ11-14.
