Comparative StudyThe 2014 New York State Medicaid Expansion and Severe Maternal Morbidity During Delivery Hospitalizations.
Medicaid expansions under the Affordable Care Act have increased insurance coverage and prenatal care utilization in low-income women. However, it is not clear whether they are associated with any measurable improvement in maternal health outcomes. In this study, we compared the changes in the incidence of severe maternal morbidity (SMM) during delivery hospitalizations between low- and high-income women associated with the 2014 Medicaid expansion in New York State. ⋯ Implementation of the Medicaid expansion in 2014 in New York State is associated with a small but statistically significant reduction in the incidence of SMM in low-income women compared with high-income women.

Comparative StudyFiber-Needle Swept-Source Optical Coherence Tomography for the Real-Time Visualization of the Transversus Abdominis Plane Block Procedure in a Swine Model.
Fascia blocks (eg, the transversus abdominis plane [TAP] block) target the intermuscular fascia layers. Ultrasound techniques have allowed peripheral blocks to be performed with accuracy and safety, however, with limitations. Optical coherence tomography (OCT) is based on low-coherence interferometry. In this study, we examined the ability of OCT to identify the TAP. ⋯ This study introduced a novel needle imaging probe method to identify the transversus abdominis fascia plane in real-time. Quantitative calculation of the attenuation coefficients can further aid objective identification by providing direct confirmation of the tip position, increasing the first-pass success rate, and decreasing the need for needle repositioning. Combining OCT and ultrasound may improve the accuracy of anesthetics placement.
