Cross-protection to new drifted influenza A(H3) viruses and prevalence of prote...
Guiomar, Raquel; Pereira da Silva, Susana; Conde, Patrícia; Cristóvão, Paula; Maia, Ana Carina; Pechirra, Pedro; Rodrigues, Ana Paula; Nunes, BaltazarIntroduction: Immune profile for influenza viruses is highly changeable over time. Serological studies can assess the prevalence of influenza, estimate the risk of infection, highlight asymptomatic infection rate and can also provide data on vaccine coverage. The aims of the study were to evaluate pre-existing cross-protection against influenza A(H3) drift viruses and to assess influenza immunity in the Portugu...

Guiomar, Raquel; Cristóvão, Paula; Conde, Patrícia; Costa, Inês; Pechirra, Pedro; Rodrigues, Ana Paula; Pereira da Silva, Susana; Nunes, BaltazarBACKGROUND: Population immune profile for influenza is highly affected by circulating influenza viruses, thus changing the risk of infection for influenza. This study aims to assess influenza immunity in the Portuguese population by age groups, during 2014 and 2015 and establish a relationship between seroprotection and circulating influenza viruses in 2014/15 and 2015/16 seasons. METHODS: Two cross-sectional s...
Plasma osteopontin is a biomarker for the severity of alcoholic liver cirrhosis...
Simão, Adélia; Madaleno, João; Silva, Nuno; Rodrigues, Fernando; Caseiro, Paula; Costa, José Nascimento; Carvalho, ArmandoBackground: Implementation of surveillance programs for at-risk populations and identification of biomarkers for early hepatocellular carcinoma (HCC) detection are a major public health goal. Recently, osteopontin (OPN) has attracted attention as a promising biomarker, with some potential advantages compared to alpha-fetoprotein (AFP), but its role in the context of alcoholic cirrhosis has never been assessed. ...
