Barriers and Facilitators of Adherence to Oral Nutritional Supplements Among People Living With Cancer: A Systematic Review.

This study aims to synthesize the barriers and facilitators of oral nutritional supplement adherence in people with cancer and assess levels of adherence. Databases including Embase, PubMed, Web of Science, Cochrane Library, Chinese National Knowledge Infrastructure, Wanfang Database, and Chinese Scientific Journal Database, were used to search articles before January 4, 2021. Eighteen studies with 1,267 participants met the inclusion criteria. All studies reported rates of adherence, ranging from 6.0% to 96.9%. Gastrointestinal intolerances and disliked tastes were considered common barriers to cancer patients' adherence, whereas the ONS management strategy was considered the most crucial facilitator of adherence. Health professionals can improve adherence through regular monitoring and guidance and incentive strategies, and paying attention to the management and prevention of adverse reactions when prescribing nutritional products.

Effects of gibberellic acid (GA3 ) application before anthesis on rachis elongation and berry quality and aroma and flavour compounds in Vitis vinifera L. 'Cabernet Franc' and 'Cabernet Sauvignon' grapes.

BACKGROUND: Gibberellic acid (GA3 ), a plant-growth regulator, is often used to obtain enlarged table grape berries and induce seedlessness in them. However, the effects of GA3 on rachis elongation and bunch compactness have seldom been reported in wine-grape production. We assessed the effects of GA3 spraying on wine-grape inflorescences and bunches and their practical implications for viticulture in the Jiaodong Peninsula, China. RESULTS: Various GA3 concentrations were sprayed on field-grown Vitis vinifera L. 'Cabernet Franc' (CF) and 'Cabernet Sauvignon' (CS) grapevines before anthesis in the Jiaodong Peninsula, China, in 2015 and 2016. Inflorescence length during berry development was measured, and flavonoids and aroma compounds in the fruit were detected by high-performance liquid chromatography - mass spectrometry (HPLC-MS) and gas chromatography - mass spectrometry (GC-MS), respectively. For both cultivars, 50 and 100 mg L-1 GA3 caused significant elongation of the rachis, whereas there was no significant effect on inflorescence growth and berry seed number. Anthocyanin, flavonol, and flavan-3-ol levels in mature berries were not significantly influenced by GA3 spraying, whereas C13 -norisoprenoids were modified. CONCLUSION: The application of 50-100 mg L-1 GA3 prior to grapevine anthesis caused elongation of inflorescences and bunches, and eased cluster compactness in CF and CS, and no negative effects were observed on the yield and seed numbers. The concentration and composition of flavonoids and most aroma compounds were not influenced, except that the norisoprenoids were increased by 50 mg L-1 GA3 applications. © 2020 Society of Chemical Industry.
