RESUMO
OBJECTIVE: Although colorectal cancer screening (CRCS) is a public health priority, uptake is suboptimal in under-resourced groups. Noninvasive modalities, including stool deoxyribonucleic acid (sDNA) testing, may mitigate economic, geographic, cultural, or impairment-related barriers to CRCS. We assessed use of sDNA testing and other CRCS modalities in U.S. residents, comparing subgroups defined by several social determinants of health (SDOH). METHODS: A nationally representative sample of community-dwelling respondents aged 50-75 years self-reported use of CRCS modalities in the 2020 Behavioral Risk Factor Surveillance System Survey. Statistical analyses assessed up-to-date screening status and choice of modality in the recommended screening interval. RESULTS: Of 179,833 sampled respondents, 60.8% reported colonoscopy, 5.7% sDNA testing, 5.5% another modality. The rate of up-to-date screening was 72.0% overall and negatively associated with Hispanic ethnicity (63.6%), lower educational and annual income levels (e.g., Assuntos

RESUMO
The white-chinned petrel (Procellaria aequinoctialis) is a seabird widely distributed in the circumpolar sub-Antarctic islands and subtropical regions, including Brazilian waters. Among the parasites present on the white-chinned petrel are the chewing lice. This seabird is parasitized by 4 known lice species to date. In this study we evaluated the ectoparasites of 2 white-chinned petrels rescued by an animal rehabilitation center in Rio de Janeiro, Brazil and recorded 4 species of chewing lice, of which 3 are already known for this host. One of the species however, has never been recorded in Brazil and another one has never been recorded parasitizing P. aequinoctialis, making this a new host record.

The brown booby (Sula leucogaster Boddaert, 1783) has a wide geographic distribution, being found throughout the intertropical range except for the west coast of South America. Chewing lice (Phthiraptera: Amblycera and Ischnocera) are ectoparasites commonly found in association with a wide variety of bird species, and extensive infestations can lead to severe itching and irritation that causes skin lesions, damage to the plumage, and abandonment of nests. Sula leucogaster lice have an atypical distribution, not fully following the distribution of their host. In the years 2018 and 2019, 4 marine animal rehabilitation centers located in Rio de Janeiro and São Paulo, Brazil received live birds and carcasses of Sula leucogaster. The animals were deloused and lice of 2 different species were collected. Identification was performed by optical microscopy, and the species found were Eidmanniella albescens Piaget, 1880 and Pectinopygus garbeiPessoa and Guimarães, 1935. This is the first record of both species in Rio de Janeiro.
