Social media use continues to grow among pathologists. Discussions of current topics, posts of educational information, and images of pathological entities are commonly found and distributed on popular sites such as Facebook and Twitter. However, little is known about the presence of neuropathology content in social media and the audience for such content. We designed and distributed a survey to assess the demographics of users viewing neuropathology content and their opinions about neuropathology in social media. User posts on the Facebook group, Surgical Neuropathology, were also analyzed. The results show that there is a demand for neuropathology content of high quality, curated by experts, and that this demand is present among both specialists and nonspecialists. These findings suggest that social media may be useful for rapid dissemination of information in the field of neuropathology. This format also offers a unique opportunity to extend the reach of information to nonneuropathologists who may not receive neuropathology journals or have access to specialty-level neuropathology training, to build networks between professionals, and potentially to influence public opinion of neuropathology on an international scale.
Despite the immunotherapeutics and target therapy agents, the survival of patients with advanced melanoma is still low. Notch signaling is able to regulate many aspects of melanomagenesis. Comparative analyses of common melanocytic nevi, dysplastic nevi and melanomas demonstrated increased expression of Notch1, Notch2 and their ligands, indicating that a positive regulation of these components may be related to the progression of melanoma. Some strategies such as gamma-secretase inhibitors (GSI) have been explored in patients with refractory metastatic disease or locally advanced disease of solid tumors. Two major classes of Notch inhibitors are currently in clinical development: GSI and monoclonal antibodies against Notch receptors or their ligands. Inhibition of Notch by GSI has been shown to decrease melanoma growth. GSI RO4929097 co-administered with cisplatin, vinblastine and temozolomide promotes greater elimination of tumor cells. The Notch pathway needs to be explored in the treatment of melanoma.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
