We suggest that the cCTG + AFI score may be of value in the prediction of neonatal acidemia and help in the management of third-trimester high-risk pregnancies.

Background: In the last few years the possible etiological role of the Hepatitis B virus (HBV) in the outbreak of extrahepatic pathologies has being studied, including lymphomas. The World Health Organization (WHO) estimates that around 257 million people live with chronic HBV infection, to date the vaccine is the most effective means of prevention. Objective: The aim of this review was to evaluate whether the vaccination against Hepatitis B can lead to reduction in lymphoma cases and have a protective role. Methods: A literature search was conducted in April 2020 using the databases Scopus, PubMed and ISI Web of Science. Search terms included: “Hepatitis B vaccination AND lymphoma”. All articles were selected evaluating the association between Hepatitis B vaccination and the prevention of lymphoma. No limits were applied. Results: Eight studies were eligible to be included in the review. Data showed that association between lymphoma and HBV infection is not the same for all types of lymphoma, but it appeared to be more significant for Non-Hodgkin lymphoma (NHL). The results from all the considered articles were not unitary. This is because studies came from many different countries with different endemicity of Hepatitis B, different vaccination coverage, treatment of chronic Hepatitis and prevention of its complications, as well as the availability of data for researchers. No statistically significant association was found between HBV vaccination and development of lymphomas. Conclusion: Although the literature is still largely lacking regarding the protective effect of anti-HBV vaccination on lymphoma subtypes, the association between HBV infection and lymphoma has been confirmed in several studies. Vaccination programs eliminate the risk of HBV infection and prevent liver disease but can also indirectly reduce the risk of lymphomas.
