Throughout her hospital course, factor V levels were managed per recommendation from her hematologist, which included transfusing fresh frozen plasma (FFP) to maintain a factor V level of 50% before any neuraxial technique and 40% for postpartum hemostasis. The parturient required multiple transfusions of FFP to stay at this level, which eventually resulted in pulmonary edema. Given the request to maintain high levels of factor V, the parturient was transfused with platelets as an alternative source of factor V. The parturient eventually delivered a healthy neonate without signs of postpartum hemorrhage or epidural hematoma.CONCLUSIONA major learning point from this case is that platelet transfusion...

Furthermore, clinical studies suggest that a subset of EEG biomarkers is associated with symptoms. This review addresses the relationship between EEG and behavior in preclinical models of N-methyl-d-aspartate (NMDA)-receptor hypofunction, as well as how these models can be used to screen therapies. Data from schizophrenia patients are juxtaposed with data from animal models, and EEG and behavioral data from mice with disruption of NMDA receptors in excitatory and/or inhibitory neurons are then compared to the pattern observed in schizophrenia. Also discussed are results following exposure to potential therapeutic agents, including GABAB agonists. Furthermore, evide...
