Background: Placement of central venous access devices is a clinical procedure associated with some risk of adverse events and with a relevant cost. Careful choice of the device, appropriate insertion technique, and proper management of the device are well-known strategies commonly adopted to achieve an optimal clinical result. However, the environment where the procedure takes place may have an impact on the overall outcome in terms of safety and cost-effectiveness. Methods: We carried out a retrospective analysis on pediatric patients scheduled for a major neurosurgical operation, who required a central venous access device in the perioperative period. We divided the patients in two groups: in group A the central venous access device was inserted in the operating room, while in group B the central venous access device was inserted in the sedation room of our Pediatric Intensive Care Unit. We compared the two groups in terms of safety and cost-effectiveness. Results: We analyzed 47 central venous access devices in 42 children. There were no insertion-related complications. Only one catheter-related bloodstream infection was recorded, in group A. However, the costs related to central venous access device insertion were quite different: euro330-euro540 in group A versus euro105-euro135 in group B. Conclusion: In the pediatric patient candidate to a major neurosurgical operation, preoperative insertion of the central venous access device in the sedation room rather than in the operating room is less expensive and equally safe.

Direct oxidative coupling of alcohols with amines using a non-precious metal oxide catalyst under mild conditions is highly desirable for imine synthesis. In this work, a mesoporous Mn1ZrxOy solid solution catalyst prepared by a co-precipitation method showed excellent catalytic performance in imine synthesis from primary alcohols and amines without base additives in an air atmosphere. XRD, N-2 physisorption, H-2-TPR, O-2-TPD, EPR and XPS were comprehensively used to unravel its structural, redox and amphoteric properties that closely depended on the interaction between MnOy and ZrO2 with a variable Zr ratio. The Mn1Zr0.5Oy catalyst presented the highest fractions of Mn3+ ions and reactive oxygen species on the surface, and the highest concentrations of acidic-basic sites, which were disclosed to play important roles in activating alcohols and molecular O-2 in the rate-determining step. In the model reaction of oxidative coupling of benzyl alcohol with aniline, such enhanced features of the Mn1Zr0.5Oy catalyst can promote the intrinsic catalytic activity (iTOF of 1.87 h(-1)) and boost benzylideneaniline formation (5.56 mmol g(cat).(-1) h(-1)) based on a >99% yield at 80 degrees C respectively at a fast response. It can also work effectively at a room temperature of 30 degrees C, as well as for the gram-grade synthesis. This is one of the best results among all the MnOy-based catalysts in the literature. Moreover, this catalyst showed good stability and a wide substrate scope with good to excellent yields of imines.

Citric acid-modified graphite-like carbon nitride materials (GCN-zCA) were synthetized by thermal copolymerization of dicyandiamide with different amounts of citric acid (z = between 5 and 25 mg). The resulting materials presented surface porosity, defective polymeric structure, and enhanced visible light absorption in the 450-700 nm range, attributed to the existence of mid-gap states and n-pi* electronic transitions. All the modified catalysts presented high selectivity (>99 %) towards the conversion of p-anisyl alcohol into p-anisaldehyde under visible-LED irradiation, the best performing photocatalyst (GCN-20CA) reaching 63 % yield (contrasting with 22 % obtained with bulk GCN) after 240 min reaction. GCN-20CA was also applied for hydrogen generation from water splitting. The modified material practically duplicated the hydrogen production when compared to bulk GCN (75 and 44 mu mol H-2 evolved in three hours, respectively), by using platinum nanoparticles as co-catalyst and EDTA as sacrificial electron donor. Moreover, p-anisyl alcohol was successfully used as sacrificial agent for water splitting, with simultaneous production of p-anisaldehyde and H-2. Reusability tests showed that GCN-20CA remained stable in a series of consecutive runs both for p-anisaldehyde synthesis and hydrogen production.
