    Abstract Hypertriglyceridemia-induced acute pancreatitis (HTG-AP) is the third most common cause of AP after gallstones and alcohol. Supportive measures, intravenous insulin, and plasmapheresis are possible treatment modalities for HTG-AP; however, definitive guidelines evaluating the best therapeutic approach are not clearly established. We present a rare case of a 42-year-old male without known comorbidities who was found to have HTG-AP. Despite early initiation of intravenous insulin and plasmapheresis and the initial decline in his triglycerides level, his condition was complicated by necrotizing pancreatitis and subsequent multi-organ failure. Future studies are warranted to evaluate the role of plasmapheresis in HTG-AP and its efficacy.

    Abstract Abstract: The Neonatal Fc Receptor (FcRn) is integral to a wide variety of processes including IgG recycling, serum albumin turnover, and bacterial opsonization. Thus, targeting FcRn will increase antibody degradation including pathogenic IgGs. FcRn inhibition provides a novel therapeutic mechanism by which autoantibody titers are reduced resulting in clinical improvement and disease abatement. The FcRn targeting mechanism is similar to that of intravenous immunoglobulin (IVIg) in which saturated FcRn facilitates accelerated pathogenic IgG degradation. Recently, the FcRn inhibitor efgartigimod was approved for the treatment of myasthenia gravis. Subsequently, clinical trials of this agent have been conducted for numerous inflammatory conditions involving pathogenic autoantibodies. These disorders include the Guillain-Barre syndrome, chronic inflammatory demyelinating polyneuropathy, and inflammatory myositis. Other disorders traditionally treated with IVIg may also benefit from FcRn inhibition in certain contexts. This manuscript discusses the mechanism of FcRn inhibition, preclinical data, and the results of clinical trials of this agent for a wide range of neuromuscular diseases.

    Abstract Background: To investigate the association of optic neuritis (ON) after the COVID-19 vaccines.
    Methods: Cases of ON from Vaccine Adverse Event Reporting System (VAERS) were collected and divided into the prepandemic, COVID-19 pandemic, and COVID-19 vaccine periods. Reporting rates were calculated based on estimates of vaccines administered. Proportion tests and Pearson χ 2 test were used to determine significant differences in reporting rates of ON after vaccines within the 3 periods. Kruskal-Wallis testing with Bonferroni-corrected post hoc analysis and multivariable binary logistic regression was used to determine significant case factors such as age, sex, concurrent multiple sclerosis (MS) and vaccine manufacturer in predicting a worse outcome defined as permanent disability, emergency room (ER) or doctor visits, and hospitalizations.
    Results: A significant increase in the reporting rate of ON after COVID-19 vaccination compared with influenza vaccination and all other vaccinations (18.6 vs 0.2 vs 0.4 per 10 million, P < 0.0001) was observed. However, the reporting rate was within the incidence range of ON in the general population. Using self-controlled and case-centered analyses, there was a significant difference in the reporting rate of ON after COVID-19 vaccination between the risk period and control period ( P < 0.0001). Multivariable binary regression with adjustment for confounding variables demonstrated that only male sex was significantly associated with permanent disability.
    Conclusions: Some cases of ON may be temporally associated with the COVID-19 vaccines; however, there is no significant increase in the reporting rate compared with the incidence. Limitations of this study include those inherent to any passive surveillance system. Controlled studies are needed to establish a clear causal relationship.

    Abstract Tumor suppressor p53 is the most frequently mutated gene in human cancer. Mutant p53 (mutp53) not only loses the tumor suppressive activity of wild type p53, but often gains new oncogenic activities to promote tumorigenesis, defined as mutp53 gain of function (GOF). While the concept of mutp53 GOF is well-established, its underlying mechanism is not well-understood. AKT has been suggested to be activated by mutp53 and contribute to mutp53 GOF, but its underlying mechanism is unclear. In this study, we found that the activation of the Rac1 signaling by mutp53 mediates the promoting effect of mutp53 on AKT activation. Blocking Rac1 signaling by RNAi or a Rac1 inhibitor can inhibit AKT activation by mutp53. Importantly, targeting Rac1/AKT can greatly compromise mutp53 GOF in tumorigenesis. Results from this study uncover a new mechanism for AKT activation in tumors, and reveal that activation of AKT by mutp53
