Introduction: Parvoviruses are DNA viruses of small size. There have been a number of reports indicating the possible effects of B19 infections during pregnancy. These effects include spontaneous abortions, stillbirth, fetal damage, and quite often, fetal anemia with hydrops fetalis. Aim: The aim of this study was the correlation of Epstein-Barr virus (EBV) and parvovirus-B19 infections with inflammation levels in placental tissue coming from spontaneous abortions and elective terminations cases. We also investigated whether viral presence could cause spontaneous abortions by associating the expression levels of inflammatory markers with adverse pregnancy outcomes. Materials and methods: One hundred ninety-four placental samples were used, 152 included in the study group coming from spontaneous abortions while 42 controls were used from cases of elective terminations. Hematoxylin and eosin (H&E) staining was performed to investigate morphological changes in the tissues, and then indirect immunohistochemistry to evaluate the expression of TNF-α, IL-6, IL-1α, B19, and EBV. Statistical analysis was performed using SPSS v. 19.0 (IBM). Results: Higher inflammation levels were observed with statistical significance in the spontaneous abortions group (p<0.001) and they were correlated with statistical significance with B19 or EBV presence (p<0.001). Viral presence was only found in the spontaneous abortions group. Both simple and multiple logistic regression confirmed that viral presence was an independent prognostic factor for high expression of all inflammatory biomarkers with statistical significance (p<0.001). Conclusions: Our results clearly indicate a specific pattern. Viral presence can deregulate inflammatory processes in the maternal-fetal environment and thus work as a trigger for spontaneous abortions.

Hepatocellular carcinoma (HCC) is one the most common primary malignancies with high mortality and morbidity. The melanoma-associated antigen (MAGE) gene family includes several genes that are highly expressed in numerous human cancers, making many of them part of the cancer-testis antigen (CTA) family. MAGE-C1 is expressed in various malignancies but is absent in normal cells, except for the male germ line. Its presence is associated with a worse prognosis, increased tumor aggressiveness, and lymph node invasion. Similarly, MAGE-C2 is linked to the development of various malignant tumors. Despite these associations, the roles and mechanisms of MAGE-C1/MAGE-C2 in HCC remain unclear. This study aimed to evaluate the expression of MAGE-C1 and MAGE-C2 in HCC and correlate it with clinicohistological characteristics. Our findings indicated that MAGE-C1 expression is associated with a higher number of nodules, elevated AFP levels, HBV or HCV positivity, older age, male sex, and lymph node invasion. MAGE-C2 expression was correlated with these characteristics and the presence of cirrhosis. These results align with the limited literature, which suggests a correlation between MAGE expression and older age and HBV infection. Consequently, our study suggests that MAGE-C1 and MAGE-C2 are promising novel biomarkers for prognosis and potential therapeutic targets in HCC.
