Arginine combination with fluoride and calcium glycerophosphate: effects of concentration and on biofilm fluid.

To study the influence of varying concentrations of arginine (Arg) combined with fluoride (F) and/or calcium glycerophosphate (CaGP) on biofilms. Biofilms were analyzed for acidogenicity, microbial viability and Ca, F and inorganic phosphorus (P) concentrations. For total bacteria, the lowest viability was found in F-containing groups, regardless of the arginine concentrations and presence of CaGP.

COVID-19 (SARS-CoV-2) infection and thrombotic conditions: A systematic review and meta-analysis.

Background: COVID-19 is an infectious disease caused by SARS-CoV-2 associated with haematological manifestations (thrombolytic events).

Aims: Considering the high prevalence of the thrombotic scenarios associated with COVID-19, the aim of this study was to perform a systematic review of the available literature, concerning the relation of COVID-19 and the thrombotic events, and identify prognostic factors for these events.

Materials & Methods: PubMed, Web of Science and Scopus databases were searched.
