Not only are they at risk for neonatal complications, such as necrotizing enterocolitis and respiratory distress syndrome, but they are at significantly increased risk for long-term complications such as neurodevelopmental impairment. Indeed, prematurity is a primary etiologic factor for cerebral palsy (CP). This article is protected by copyright.

However, they are expensive, time consuming and demand huge efforts from participants, researchers and the clinical services that facilitate them. Even when trials are successfully completed, peer reviewers often find them wanting. One of the most common criticisms is a 'lack of power' to tackle clinically important outcomes.

DESIGN This is a retrospective study. SETTING Twelve hospitals in northern Italy. PARTICIPANTS Pregnant women with COVID-19 confirmed infection who delivered. EXPOSURE COVID 19 infection in pregnancy. METHODS SARS-CoV-2 infected women who were admitted and delivered during the period 1-20 march 2020 were eligible. Data were collected from the clinical records using a standardized questionnaire on maternal general characteristics, any medical or obstetric co-morbidity, course of pregnancy, clinical signs and symptoms, treatment of COVID 19 infection, mode of delivery, neonatal data and breastfeeding MAIN OUTCOME AND MEASURE Data on mode of delivery and neonatal outcome RESULTS 42 women with COVID-19 delivered at the participating centres 24(57,1%, 95% CI= 41,0-72,3) delivered vaginally. An elective cesarean section was performed in 18/42 (42,9%, 95%CI 27,7-59,0) cases in 8 cases the indication was unrelated to COVID-19 infection. Pneumonia was diagnosed in 19/42(45,2%, 95%CI 29,8-61,3) cases of these 7/19(36,8%,95CI 16,3-61,6) required oxygen support and 4/19(21,1%,95%CI=6,1-45,6) were admitted to a critical care unit. Two women with COVID-19 breastfed without a mask because infection was diagnosed in the post-partum period their new-borns tested positive for SARS-Cov-2 infection. In one case a new-born had a positive test after a vaginal operative delivery. CONCLUSIONS Although post-partum infection cannot be excluded with 100% certainty, these findings suggest that vaginal delivery is associated with a low risk of intrapartum SARS-Cov-2 transmission to the new-born.

Previous studies proved that CD147 plays a crucial function in melanoma cell metastasis and invasion through matrix metalloproteinase 9 (MMP-9) expression; however, the details of how CD147 regulates MMP-9 expression remain elusive. In this study, we demonstrated that CD147 and NFAT1 are overexpressed in the tissues of patients with primary and metastatic melanoma, which has shown a positive correlation. Further, we observed that CD147 regulates NFAT1 activation through the [Ca2+ ]i-calcineurin pathway. Knock down of NFAT1 significantly suppresses melanoma metastasis, and we demonstrated that CD147 affects melanoma metastasis in an NFAT1-dependent manner. Moreover, we verified that NFAT1 directly binds to MMP-9 promoter. Inhibition of CD147 expression significantly abrogates MMP-9 promoter luciferase gene reporter activity as well as N
