Purpose Of Review: This review discusses recent articles on various aspects of the prevention of mother-to-child transmission during pregnancy and delivery.

Recent Findings: Rapid human immunodeficiency virus (HIV) testing of women in labour whose status is not known allows the prompt treatment of mother and baby to reduce transmission risk. The feared clinical resistance in the mother after treatment with a single dose of nevirapine has been confirmed. Strategies are required to minimize this resistance and allow the use of nevirapine for treatment of the mother. There are new findings of mitochondrial toxicity in babies who have been exposed to anti-retroviral medicines during pregnancy or delivery, but the clinical implications are not clear. Long-term follow-up of exposed children is required. Resource-poor countries are starting to use multiple drugs to further reduce transmission to the infant. These efforts are reducing the rates of transmission to the level found in affluent countries.

Summary: Improvements in treatment continue to reduce the risk of HIV transmission from mother to child in resource-poor countries, but subsequent maternal resistance continues to be a problem since treatment for the mother's health is now possible. The long-term effects on the infant are still not understood.

Atezolizumab plus bevacizumab as first-line treatment of unresectable hepatocellular carcinoma: interim analysis results from the phase IIIb AMETHISTA trial.

ESMO Open

Background: The treatment of advanced hepatocellular carcinoma (HCC) with atezolizumab and bevacizumab led to significant improvements in overall survival (OS), progression-free survival (PFS), and response rate compared with sorafenib in the phase III IMbrave150 trial. The etiology of background liver disease can differ between Eastern and Western populations, leading to a potentially different impact of systemic therapies; therefore the unequal representation must be considered in the IMbrave150 trial. To provide further data on the safety and effectiveness of atezolizumab and bevacizumab, the phase IIIb AMETHISTA (Atezolizumab plus bevacizumab in METastatic HCC Italian Safety TriAl) ran in a Western (Italian) population of patients with advanced HCC.
