    Tobacco use has been identified as a major risk factor for oral disorders such as cancer and periodontal disease. Tobacco use cessation (TUC) is associated with the potential for reversal of precancer, enhanced outcomes following periodontal treatment, and better periodontal status compared to patients who continue to smoke. Consequently, helping tobacco users to quit has become a part of both the responsibility of oral health professionals and the general practice of dentistry. TUC should consist of behavioural support, and if accompanied by pharmacotherapy, is more likely to be successful. It is widely accepted that appropriate compensation of TUC counselling would give oral health professionals greater incentives to provide these measures. Therefore, TUC-related compensation should be made accessible to all dental professionals and be in appropriate relation to other therapeutic interventions. International and national associations for oral health professionals are urged to act as advocates to promote population, community and individual initiatives in support of tobacco use prevention and cessation (TUPAC) counselling, including integration in undergraduate and graduate dental curricula. In order to facilitate the adoption of TUPAC strategies by oral health professionals, we propose a level of care model which includes 1) basic care: brief interventions for all patients in the dental practice to identify tobacco users, assess readiness to quit, and request permission to re-address at a subsequent visit, 2) intermediate care: interventions consisting of (brief) motivational interviewing sessions to build on readiness to quit, enlist resources to support change, and to include cessation medications, and 3) advanced care: intensive interventions to develop a detailed quit plan including the use of suitable pharmacotherapy. To ensure that the delivery of effective TUC becomes part of standard care, continuing education courses and updates should be implemented and offered to all oral health professionals on a regular basis

    Probing the Bioactive Constituents from Chemotypes of the Sponge Psammocinia aff. bulbosa

    Since the report of (+)-psymberin (2) in 2004, many synthetic groups have pursued the synthesis of this compound, and our group has further collected Psammocinia aff. bulbosa to successfully isolate more 2. With more (+)-psymberin (2) in hand, additional clonogenic studies, a therapeutic efficacy assessment, and the hollow fiber assay have been completed. The inconsistent production of (+)-psymberin (2) and the classification of six Psammocinia species are further discussed herein. The most recent of these six collections resulted in the isolation of a new brominated cyclic peptide, (-)-psymbamide A (4), which is the first report of a Psammocinia-derived compound in this peptide class. The planar structure was solved via dereplication with Marinlit, HRESIMS, and 1D and 2D NMR techniques, and the absolute configuration determined using Marfey’s method
