Mercury levels in Southern Ocean squid: Variability over the last decade. Chemosphere. 2020 Jan;239:124785 Authors: Seco J, Xavier JC, Brierley AS, Bustamante P, Coelho JP, Gregory S, Fielding S, Pardal MA, Pereira B, Stowasser G, Tarling GA, Pereira E Abstract The concentrations of total and proportions of organic mercury were measured in tissues of 355 individuals of 8 species of Southern Ocean squid (Alluroteuthis antarcticus, Bathyteuthis abyssicola, Filippovia knipovitchi, Galiteuthis glacialis, Gonatus antarcticus, Kondakovia longimana, Psychroteuthis glacialis and Slosarczykovia circumantarctica). Squid were caught around South Georgia (Scotia Sea) during 5 cruises, between the austral summers of 2006/07 to 2016/17 to evaluate temporal changes in bioaccumulation and tissue partitioning. Total mercury concentrations varied between 4 ng g-1 and 804 ng g-1 among all tissues. Net accumulation of mercury in muscle with size was observed in A. antarcticus, B. abyssicola and P. glacialis, but no relationship was found for S. circumantarctica and lower concentrations were observed in larger individuals of G. glacialis. Muscle tissues had the highest mercury concentrations in the majority of species, except for F. knipovitchi for which the digestive gland contained highest concentrations. In terms of the percentage of organic mercury in the tissues, muscle always contained the highest values (67%-97%), followed by the diges...
DiscussionThe interventions of education and medication alerts resulted in a significant increase in the percentage of patients receiving appropriate doses of dilTIAZem and a nonsignificant decrease in the incidence of hypotension. This process-oriented intervention resulted in an improvement in appropriate dilTIAZem doses at our site. Rate control was not statistically significantly different between the 2 groups. Long-term sustainability of this intervention requires further study.
ConclusionsVitamin D insufficiency was prevalent in both newly diagnosed axSpA patients and healthy controls. There was no association between vitamin D and pain and disease activity in the newly diagnosed axSpA patients. Monitoring vitamin D levels is important and early intervention for vitamin D insufficiency is needed, especially in female patients.
ConclusionVacuum assisted dressing is more effective than traditional wound dressing in wound healing of open fractures.
This study aims to reflect on the process of adoption of the preprints publication model, briefly delimiting its history and current use by the national and the international scientific community. Departing from the literature and a consultation of preprint repositories, this reflection intends to highlight the main challenges that preprint implementation will face in the Nursing area, along with its specificities. While considering its benefits for scientific dissemination, this study points out the difficulties that may arise from the implementation of mostly north-American science models in a peripheral country such as ...

CONCLUSIONS: Neonatal screening with the red reflex is not sufficient to detect intraocular disease. A normal neonatal red reflex does no exclude intraocular disease. It has a specificity of nearly 90%, but its sensitivity is only 56%. Most retinal haemorrhages are undiagnosed as they cannot be detected with a red reflex.
