Environ Sci Pollut Res Int 2021 Sep 22. Epub 2021 Sep 22.

Universidade de São Paulo, São Paulo, SP, Brazil.

Beaches with monazitic sands show high natural radiation, and the knowledge of this radiation is fundamental to simulate the effects of natural terrestrial radiation on biological systems. Monazite-rich sand from a beach in the southeastern Brazil were collected and analyzed by X-ray fluorescence, X-ray diffraction, and magnetic susceptibility. The natural terrestrial radiation of the beach sand showed a positive correlation with the Th and Y elements, which are closely associated with Ce, Nd, Ca, and P, suggesting that this grouping is mainly associated with local natural radiation.

PeerJ 2021 30;9:e12096. Epub 2021 Aug 30.

Natural Resources and Environmental Management, University of Hawai'i at Mānoa, Honolulu, Hawai'i, United States of America.

Many seabird populations are declining globally, but successful conservation efforts have led to population expansion of some species into human-dominated landscapes. Thus, there is an increased potential for direct human and seabird interactions for certain species in human-occupied areas, with nest-site characteristics potentially affecting the susceptibility of nests to human disturbance. We assessed the effect of human activity and nest-site characteristics on Wedge-tailed Shearwater ( '') nesting success at two breeding colonies, one with human exposure and one without, located in Kailua, O'ahu, Hawai'i.

PLoS One 2021 15;16(9):e0251469. Epub 2021 Sep 15.

Centre for Epidemiology and Biostatistics, University of Melbourne, Parkville, Victoria, Australia.

Colorectal cancer risk stratification is crucial to improve screening and risk-reducing recommendations, and consequently do better than a one-size-fits-all screening regimen. Current screening guidelines in the UK, USA and Australia focus solely on family history and age for risk prediction, even though the vast majority of the population do not have any family history. We investigated adding a polygenic risk score based on 45 single-nucleotide polymorphisms to a family history model (combined model) to quantify how it improves the stratification and discriminatory performance of 10-year risk and full lifetime risk using a prospective population-based cohort within the UK Biobank.
