Impact of cumulative glucocorticoid exposure on vancomycin clearance in hospitalized children: A retrospective cohort study

British Journal of Clinical Pharmacology, EarlyView.
Prior glucocorticoid exposure is associated with modestly increased vancomycin clearance in hospitalized children, partly mediated by renal function and inflammation and may contribute to subtherapeutic early drug exposure. Abstract Introduction Augmented renal clearance (ARC) can lead to subtherapeutic vancomycin exposure in children.

Impaired healing following implant placement surgery: A case report of a modern‐day manifestation of scurvy

Clinical Advances in Periodontics, EarlyView.
Abstract Background Delayed wound healing following implant placement surgery is an uncommon complication, usually attributed to systemic (smoking and alcohol), local (severely inflamed tissues), or technical (poor suturing) factors. However, delayed wound healing after implant placement caused by severe hypovitaminosis C has not been previously ...

Carbon Dot Nano‐Spacers in Triazine Networks for Integrated Photothermal Seawater Desalination and H2O2 Production

Carbon Energy, EarlyView.
Cyanated carbon dots (CN‐CDs) are synthesized by the hydrothermal method with carboxymethyl cellulose and cyanobenzoic acid, and CD‐CTN is obtained in situ via cyclotrimerization of CN‐CDs. CD‐CTN possesses excellent photothermal catalytic H2O2 production in seawater, and desalted H2O2 could be obtained, which demonstrates the practical application for
