https://www.selleckchem.com/products/ezatiostat.html Middle meningeal artery (MMA) and middle meningeal vein (MMV) fistula is a rare lesion. Hemorrhagic propensity for this pathology has not been widely recognized. We encountered a case of idiopathic MMA-MMV fistula presenting as intracerebral hemorrhage. MMA and MMV showed a single fistula and the enlarged MMV coiled around the MMA, resembling a varix. We treated the case using endovascular techniques. This case highlights the anatomy along the course of the MMV and is unique, since no backward leptomeningeal drainage was observed. A bone defect in the meningeal groove on computed tomography and a "green caviar appearance" on angiography may be characteristic of this rare pathology.Female-assigned at birth sexual and gender minorities (FAB SGM) are at elevated risk of experiencing intimate partner violence (IPV), yet little longitudinal research has been conducted with this population. In the current study, we attempted to understand how patterns of IPV victimization and perpetration, measured across a wide range of IPV behaviors (psychological, physical, sexual, cyber, and SGM-specific), changed over time for FAB SGM youth. Participants came from a longitudinal cohort study of FAB SGM late adolescents and young adults (FAB400; N = 488) and included anyone who reported a romantic partner at one of the first three waves (six months apart; N = 433). Latent class analysis (LCA) was run at each wave to determine the best-fitting class structure across IPV experiences. These were followed up with latent transition analyses (LTAs) to determine patterns of movement between classes over the course of the three waves. Lastly, we looked at the effects of staying with the same romantic partner on transitions. We found that the same three-class structure replicated across all three waves of the study. #link# That class structure identified no/low, psychological, and high IPV classes at each wave. In the LTA, when transitions o
