Background: Totally implantable venous access devices (TIVADs) are widely used in oncology patients to facilitate central venous access. Although they offer benefits, TIVADs can be associated with complications.

Materials And Methods: This retrospective cohort study included all oncology patients 18 years or older who underwent TIVAD implantation between September 2015 and October 2019.

Introduction: Inflammatory bowel disease (IBD) is usually diagnosed when symptomatic. Prognosis and evolution of preclinical IBD is largely unknown. However, colorectal cancer screening programs (CRCSP) detect a subset of IBD patients with no symptoms.

Objective: Profileplasty traditionally involves improving a nasal hump or an underprojected chin. However, this procedure can correct other facial defects like saddle nose or prognathism. To establish the best overall profile, the nose, the midface, and the chin should be considered altogether.

This work assessed the efficiency and sustainability of ultrasound-assisted extraction (UAE) of anthocyanins from grape pomace using bio-based solvents: Ethanol, Isopropanol, Propylene-glycol, and Ethylene-glycol at different concentrations (50 and 100 % v/v) and temperatures (25 °C and 50 °C). Higher ultrasonic intensities (UI) were obtained at 50 °C and 50 % v/v by decreasing solvents viscosities. Under these conditions, anthocyanin extractions were performed with different combinations of solvent to liquid ratio (SLR) at 1:10 and 1:50 g/mL, and UI (3.

Brine mining can represent a valuable non-conventional resource for the extraction of Mg, Li, B, Sr and other Trace Elements (TEs) such as Rb, Cs, whose recoveries require chemical reagents such as alkaline and acidic solutions. In a circular strategy, these required chemicals can be produced in-situ through Electrodialysis with Bipolar Membranes (EDBM). In this work, a laboratory EDBM unit was operated using real brines from Trapani saltworks to investigate, for the first time, the migration of minor and trace ions, as Li, B, Sr, Cs and Rb through ion-exchange membranes (IEMs).
