Aim: To evaluate whether a daily full-dose aspirin regimen after anterior cruciate ligament (ACL) reconstruction reduces the risk of postoperative symptomatic deep-venous thrombosis (DVT).Materials and Methods: Single-center retrospective cohort study of patients who underwent ACL reconstruction from 2007 to 2016. One thousand two hundred thirty-three patients met inclusion criteria: 821 patients received no chemoprophylaxis and 412 patients received daily full-dose aspirin.Results: A total of 10 patients, seven receiving no chemoprophylaxis and three using aspirin, sustained a postoperative symptomatic DVT. Calculated adjusted odds ratio for symptomatic postoperative DVT for aspirin versus no chemoprophylaxis was 0.928 (95% CI 0.237-3.629, P value = 0.91). Odds ratio for symptomatic postoperative DVT occurrence among tobacco users versus non-tobacco users was 3.76 (95% CI 1.077-13.124, P = 0.04).Conclusions: No statistically significant difference was observed in postoperative symptomatic DVT after ACL reconstruction in those who received full-dose aspirin chemoprophylaxis versus those with no chemoprophylaxis. Additionally, there was a significantly increased risk of postoperative symptomatic DVT with tobacco use. [ABSTRACT FROM AUTHOR]

Microblogs, with their interactive nature, can engage students in community building and sensemaking. Using Weick's model of organizing as a framework, we integrated the use of micromessaging to increase student engagement in the large-lecture classroom. Students asked significantly more questions and asked a greater diversity of questions when micromessaging was available to them. The microblog format facilitated student-to-student connectedness, where students could post questions to the microblog alongside questions from their peers. This communication strategy provided increased requisite variety to match the equivocal nature of the large-lecture, medical humanities classroom. [ABSTRACT FROM AUTHOR]
