RESUMO
BACKGROUND: The Community Practice (CP) surgeon is the first point of access to surgical care globally and performs the majority of procedures in the USA. CP surgeons include those of various practice models, locations and communities, education and training, and much more. It is a diverse group that drives quality, access to care, research, and innovation. The SAGES CP Committee was formed to better define the role and highlight the contribution of the CP surgeon, as well as advocate for the position of CP surgeons in our society. METHODS: In 2018, a survey was distributed to the SAGES membership asking members to self-identify as either a Community Surgeon or Academic Surgeon. RESULTS: The majority (71%) of SAGES members surveyed self-identified as "Community Surgeons." This was in stark contrast to the distribution of Community versus Academic Surgeons in SAGES leadership (25% versus 75%, respectively). CONCLUSION: By better defining the characteristics and role of the CP, SAGES will be better informed on how to effectively engage with this large group within the society and increase its representation within the leadership. The CP Committee met on a biannual basis over a period of two years focusing on assessing their role in the SAGES organization. The committee members created the following initial goals: (1) define in a broad sense the characteristics of a CP Surgeon, (2) discuss and characterize the value of the CP surgeons, (3) highlight past and future areas of contributions of the group, and (4) delineate ways to engage and represent this subgroup. This manuscript is a culmination of the work of this committee while also serving as a way to support the initiatives and direction of SAGES leadership.

Saccharification is one of the most noteworthy processes in biomass-based biorefineries. In particular, the lytic polysaccharide monooxygenase has recently emerged as an oxidative cleavage-recalcitrant polysaccharide; however, there is insufficient information regarding its application to actual biomass. Accordingly, this study focused optimizing the recombinant expression level of a bacterial lytic polysaccharide monooxygenase from Thermobifida fusca (TfLPMO), which was characterized as a cellulolytic enzyme. Finally, the synergistic effect of the lytic polysaccharide monooxygenase and a commercial cellulase cocktail on the saccharification of agrowaste was investigated. TfLPMO functioned on various cellulosic and hemicellulosic substrates, and the combination of TfLPMO with cellulase exhibited a synergistic effect on the saccharification of agrowastes, resulting in a 19.2% and 14.1% increase in reducing sugars from rice straw and corncob, respectively. The results discussed herein can lead to an in-depth understanding of enzymatic saccharification and suggest viable options for valorizing agrowastes as renewable feedstocks in biorefineries.
