Game-Based Learning in Elementary Mathematics
This paper analyzed 15 primary, peer-reviewed research articles about how to integrate game-based learning in elementary mathematics to increase conceptual understanding. The purpose of this paper was to inform teachers about how to integrate digital and traditional games, including factors to enhance effective implementation, in a way that increased conceptual understanding. Key factors were gleaned from the articles that had a significant impact on the effectiveness of game-based learning. In Chapter Two, traditional and digital games were divided into two sections to analyze the benefits and drawbacks of each method. These benefits and drawbacks were compared in the Appendices to create universal factors of both traditional and digital game-based learning. These factors included educational context, key characteristics, and the teacher’s role. Research had multiple gaps within the literature that could be filled to enhance the credibility and further validate game-based learning as a viable supplemental tool to instruction in elementary mathematics

Intrathecal B-cell activation in LGI1 antibody encephalitis.
ObjectiveTo study intrathecal B-cell activity in leucine-rich, glioma-inactivated 1 (LGI1) antibody encephalitis. In patients with LGI1 antibodies, the lack of CSF lymphocytosis or oligoclonal bands and serum-predominant LGI1 antibodies suggests a peripherally initiated immune response. However, it is unknown whether B cells within the CNS contribute to the ongoing pathogenesis of LGI1 antibody encephalitis.MethodsPaired CSF and peripheral blood (PB) mononuclear cells were collected from 6 patients with LGI1 antibody encephalitis and 2 patients with other neurologic diseases. Deep B-cell immune repertoire sequencing was performed on immunoglobulin heavy chain transcripts from CSF B cells and sorted PB B-cell subsets. In addition, LGI1 antibody levels were determined in CSF and PB.ResultsSerum LGI1 antibody titers were on average 127-fold higher than CSF LGI1 antibody titers. Yet, deep B-cell repertoire analysis demonstrated a restricted CSF repertoire with frequent extensive clusters of clonally related B cells connected to mature PB B cells. These clusters showed intensive mutational activity of CSF B cells, providing strong evidence for an independent CNS-based antigen-driven response in patients with LGI1 antibody encephalitis but not in controls.ConclusionsOur results demonstrate that intrathecal immunoglobulin repertoire expansion is a feature of LGI1 antibody encephalitis and suggests a need for CNS-penetrant therapies
