COVID-19 pandemic had an impact without precedent. Pregnant women are part of the vulnerable population and the extent of SARS-CoV-2 infection consequences on obstetrical and neonatal outcome are still studied. It’s been speculated, based on what is known about other pathogenic viruses, SARS-CoV-2 virus can interfere with placental defense mechanisms and increase the miscarriage and preterm birth rate. Often, pregnant women infected with SARS-CoV-2 virus develop mild pneumonia. Severe pneumonia occurs very rarely and is statistically significant related to neonatal death. Our study has been conducted in a multidisciplinary hospital unit and included 184 pregnant women with SARS-COV-2 infection who gave birth in our hospital, diagnosed through polymerase chain reaction. There have been analyzed data regarding the maternal symptomatology, the gestational age, the method of giving birth, complications that have occurred during birth, the newborns weight and neonatal outcome through Apgar score. There have been three cases of severe infection with maternal death and one case with neonatal death.
Overall, 20% of patients had mild symptomatology, 2% had severe form and the rest of the patients were asymptomatic. We found a high rate of preterm birth and intrauterine growth restriction and an increase incidence of acute fetal distress followed by caesarean section. SARS-CoV-2 virus affects both the mother and the fetus as a whole and, subsequently, individually. Our results show the adverse obstetrical and neonatal outcome in peripartum period complicated with SARS-CoV-2 infection even in asymptomatic and mild-symptomatic cases.

The lung cancer is the leading cause of death determined by malignancies in the world, followed by breast, prostate and colon cancer. The malignant cells present a variety of genetic aberrations that can be grouped into six essential pathways: (1) the acquisition of self sufficient or autonomous growth signals
(2) insensitivity to growth inhibitory signals
(3) resistance to signals of apoptosis
(4) unlimited proliferation potential
(5) sustained angiogenesis
and (6) invasion and metastasis1.
The p53 protein is a protein with molecular mass of 53 kDa (from where its name derives). The gene p53 encoding the protein p53 is located on the short arm of chromosome 14. The protein p53 is involved in maintaining control cellular genome stability and its disruption can lead to the emergence of malignancies. In about 50% of human cancers, the mutant protein p53 was detected. At the cellular level it regulating the transcription of some genes involved in cell growth control and apoptosis. The gene p53 can be inactivated by punctiform mutations and protein p53 can be inactivated by the formation of complexes with the cellular proteins or by proteolysis.
