NCCN guideline adherence in rectal cancer and outcomes in low-volume vs. high-volume centers

June 02, 2024

Poster, American Society of Colon and Rectal Surgeons Annual Scientific Meeting, Baltimore, MD, USA

This poster investigated if adherence to National Comprehensive Cancer Network (NCCN) guidelines would reduce disparities in oncologic outcomes between rectal cancer patients treated at high-volume and low-volume centers. Using 55,497 patients from the the National Cancer Database (NCDB), we found a survival benefit associated with adherence to NCCN guidelines and treatment at high-volume centers. While controlling for NCCN adherence alone does not remove the survival benefit at high-volume centers, this analysis shows that controlling for specific high-risk tumor and patient factors can mitigate this difference.

Augmented reality in facial plastic & reconstructive surgery: A systematic review

May 15, 2024

Poster, Combined Otolaryngology Spring Meetings, Chicago, IL, USA

This poster discussed the applications, uses, and limitations of augmented reality (AR) in facial plastics and reconstructive surgery (FPRS). The most significant areas of application are within hard tissue reconstructions such as orthognathic surgery and trauma. AR has a significant applications in preoperative planning, intraoperative guidance, and postoperative assessment. The most common AR modality is head-mounted display, with computer-assisted design (CAD)/computer-assisted modification (CAM) and mobile app/monitor following closely behind. Soft tissue AR visualization, manual registration not keeping up with tissue rearrangement, and AR availability/unfamiliarity are challenges for AR applications in FPRS to break past its predominantly preclinical stage.

Novel substance use and support themes on Reddit: Lessons for researchers and practitioners

November 14, 2023

Poster, American Public Health Association Annual Meeting, Atlanta, GA, USA

This poster discussed how to leverage big data from Reddit to identify and analyze substance use and support themes in popular subreddits related to substance use. This project captured fast-evolving substance use and harm-reduction patterns that can improve practitioners’ understanding of diverse substance use experiences. Additionally, our annotated list of subreddits will help researchers immediately identify relevant online communities to monitor emerging substances and routes of administration, identify benefits of digital recovery networks, analyze substance use and support language, and develop targeted secondary prevention strategies.

Flap to floor: Free flap comparative outcomes outside the ICU

October 01, 2023

Oral Presentation, American Academy of Otolaryngology-Head and Neck Surgery Foundation Annual Meeting, Nashville, TN, USA

This presentation examined operative outcomes for patients transferred to a general ward following microvascular free flap reconstruction of the head and neck as compared to patients transferred to an intensive care unit (ICU). We found that there was no change in overall hospital length of stay (LOS), postoperative complications, readmission rates, or flap failure rates. We found a significant decrease in ICU LOS despite a significant increase in rapid responses. Transfer to a stepdown unit rather than an ICU would allow for a better quality hospital experience with improved sleep, decreased cost of care, and a higher number of available ICU beds for patients in greater need of critical care management with no significant increase in postoperative complications.

Applying social network theory to vaping in high school: Implications for school-based prevention programs

July 15, 2022

Oral Presentation, XLII International Social Networks Conference, Virtual

Vaping in high schools has skyrocketed partly due to social factors. Peer influence on risky behavior is especially potent in adolescence and varies by gender. Smoking prevention programs focused on peer-group leaders have shown great promise, and a social influence model has proved effective in understanding adult smoking networks but has not been applied to adolescent vaping. This study applies the social influence model to vaping in a high school social network and helps inform school-based vaping prevention programs by examining the roles of social network centrality and gender on vaping behavior. An online survey was emailed to a high school’s student body asking for gender, age, grade level, vape status, self-reported peer influence status, and the names of three friends. Available at github.com/njha02/surveyAnalysis, custom Java and MATLAB scripts were used to read the survey data spreadsheet, create a directed graph, compute centrality measures, and perform student’s t-tests to compare centrality measures by gender and vape status. Of 192 students in the school, 102 students responded to the survey. Students who vape were in more tightly knit friend groups than students who do not vape (p<0.05). Compared to males who vape, females who vape had more social ties to other students who vape, exhibiting greater homophily (p<0.01). Compared to females who do not vape, females who vape were in more tightly knit friend groups (p<0.05) and had more ties to other students who vape (p<0.01). Applying social network theory can reveal previously untapped information to address vaping among a unique student body. In this case, an intervention targeting close-knit networks may prove more effective for females than males, but establishing trends across student bodies requires additional research to control for differences between schools (e.g., public/private or urban/rural). This study supports a general framework for assessing peer-influenced behavior.

A preliminary network analysis of blighted neighborhoods in Baltimore City

July 14, 2022

Oral Presentation, XLII International Social Networks Conference, Virtual

Although literature exists on the contagion effect of neighborhood blight, this study aims to take the field a step further by applying network analysis to the spread of vacant properties in Baltimore. Data on vacant properties from Open Baltimore were used to create a city-wide network of vacancies. The spread of neighborhood blight was measured in different sized communities, and network metrics were leveraged to select what vacancies upon rehabilitation would minimize the influence of neighborhood blight on future vacancies. Rehabilitation programs were found to be most effective when they had a larger number of possible rehabilitations, began earlier, and selected vacant properties that exhibited higher connectivity. Although currently available network metrics are not ideal for minimizing neighborhood blight, the use of outdegree shows promise to warrant future work on developing predictive algorithms that can estimate what properties would likely become vacant and hence whose predecessors should be targeted for rehabilitation. When supplemented with sociodemographic considerations and predictive algorithms, these findings can inform the optimal selection of vacancies to rehabilitate and thus most effectively mitigate the spread of neighborhood blight.

Nuclear stiffening along with RhoGEF activity regulate RhoA/MyosinII-dependent contractility and cell migration phenotype in confinement

October 16, 2020

Poster, Biomedical Engineering Society Annual Meeting, Virtual

This presentation highlighted signaling pathways that are activated in invasive breast cancer cells when nuclei are confined during migration in synthetic microfluidic devices – a finding that can be extrapolated to contricted passageways in the body such as pre-existing perineural spaces and bone cavities or channels created by macrophages and cancer-associated fibroblasts through ECM remodeling.
