The acute reduction of rheologically relevant plasma constituents such as fibrinogen and largesized lipoproteins significantly improves whole blood and plasma viscosity by a decrease of approximately 15%, erythrocyte aggregability decreases by 53% whereas erythrocyte filtrability improves by 10% (figure 3).……展开更多

Since approval, three cases of acute hepatitis in Austrian noni juice consumers have been published, where a causal link is suggested between the liver dysfunction and ingestion of anthraquinones from the plant. Measurements of liver function in a human clinical safety study of TAHITIAN NONI Juice, as well as subacute and subchronic animal toxicity tests revealed no evidence of adverse liver effects at doses many times higher than those reported in the case studies. Additionally, M. citrifolia anthraquinones occur in the fruit in quantities too small to be of any toxicological significance. Further, these do not have chemical structures capable of being reduced to reactive anthrone radicals, which were implicated in previous cases of herbal hepototoxicity. The available data reveals no evidence of liver toxicity.展开更多

SARS-CoV-2 has the characteristics of a long incubation period and asymptomatic infection, which are undoubtedly major challenges to blood transfusion safety. Although no research has suggested that there is a risk of SARS-CoV-2 transmission through blood transfusion, the safe use of clinical blood during the epidemic is a serious problem faced by blood collection and supply institutions. Herein, we elaborate on the management of blood collection and supply during the coronavirus disease 2019 (COVID-19) pandemic from aspects such as blood inventory management, clinical blood use, and reducing the risk of transmission of SARS-CoV-2 via blood transfusion. Blood service departments should adopt flexible policies to ensure that blood collection networks can meet clinical needs, while at the same time protecting staff and blood donors, maintaining blood safety, and reducing blood risks during the epidemic.展开更多
