The number of women with major congenital heart defects reaching reproductive age is likely increasing. We herein describe the anesthetic management of a 33-year-old woman at 37 gestational weeks with a history of Glenn surgery who was undergoing an urgent cesarean section due to pathological cardiotocography. Combined spinal-epidural anesthesia was the most suitable technique for urgent cesarean section in our patient with a single ventricle and phasic flow in the pulmonary artery because it provided rapid-onset anesthesia with negligible hemodynamic effects.

Malaria is associated with high rates of morbidity and mortality worldwide, particularly in Africa, Southeast Asia and South America. Nonetheless, several cases of malaria have been reported in Western countries involving travelers from endemic areas, though very few involve pregnant women. In this article, we report a case of a young woman born in Sierra Leone who had been living in Italy for two years. She was admitted to our hospital with malaise; worsening of her condition led to Plasmodium falciparum infection diagnosis early during her hospital stay, as well as an urgent cesarean delivery. We briefly discuss the features of malaria in pregnancy, the difficulties associated with early diagnosis, and the possible fetal and maternal implications, and also consider how the disease may affect anesthetic management.

Microwave (MW)-assisted heterogeneous catalytic chemical reactions have opened advanced routinesover the conventional methodology. MW absorption ability of catalyst governed by its particle size is theforemost important factor to be considered before designing catalysts for such MW-based chemistry. Despite considerable interest in applying metallic-based catalysts for MW-assisted reactions, theinfluences of particle size on catalyst’s MW absorption ability and its resultant activity remain elusive. Here, we report an effective approach to tailor the MW absorption ability of Co3O4 catalyst via controllingits particle size during the crystal growth. A developed theoretical model verified that a capping agentcould regulate Co3O4 particle size effectively. For the unsupported Co3O4 catalysts, smaller particle sizepossessed higher MW absorption capacity and thereby delivered higher activity for MW-assisted bireformingof methane. High conversion of 63% CH4 and a syngas ratio (H2/CO) of 2.2 was achieved withthe smallest Co3O4 particles, at 20 nm. In contrast, the supported Co3O4 samples required larger particlesto ensure adequate exposure to the incident MW, which is partially covered by MW-inert support. Theresults disclose that by tailoring particles size appropriately, metallic-based catalysts can be optimisedfor MW-based chemical reactions.
