    Background: The city of Port-au-Prince, Haiti, is experiencing an epidemic of firearm injuries which has resulted in high burdens of morbidity and mortality. Despite this, little scientific literature exists on the topic. Geospatial research could inform stakeholders and aid in the response to the current firearm injury epidemic. However, traditional small-area geospatial methods are difficult to implement in Port-au-Prince, as the area has limited mapping penetration. Objectives of this study were to evaluate the feasibility of geospatial analysis in Port-au-Prince, to seek to understand specific limitations to geospatial research in this context, and to explore the geospatial epidemiology of firearm injuries in patients presenting to the largest public hospital in Port-au-Prince. Results: To overcome limited mapping penetration, multiple data sources were combined. Boundaries of informally developed neighborhoods were estimated from the crowd-sourced platform OpenStreetMap using Thiessen polygons. Population counts were obtained from previously published satellite-derived estimates and aggregated to the neighborhood level. Cases of firearm injuries presenting to the largest public hospital in Port-au-Prince from November 22nd, 2019, through December 31st, 2020, were geocoded and aggregated to the neighborhood level. Cluster analysis was performed using Global Moran’s I testing, local Moran’s I testing, and the SaTScan software. Results demonstrated significant geospatial autocorrelation in the risk of firearm injury within the city. Cluster analysis identified areas of the city with the highest burden of firearm injuries. Conclusions: By utilizing novel methodology in neighborhood estimation and combining multiple data sources, geospatial research was able to be conducted in Port-au-Prince. Geospatial clusters of firearm injuries were identified, and neighborhood level relative-risk estimates were obtained. While access to neighborhoods experiencing the largest burden of firearm injuries remains restricted, these geospatial methods could continue to inform stakeholder response to the growing burden of firearm injuries in Port-au-Prince

    Abstract Background Medical school is a challenging time, with many medical students reporting symptoms of burnout, depression, anxiety, suicidal ideation, and psychological distress during pre-clinical and clinical years. First-generation college and first-generation medical students may be two groups of students at increased risk for the negative psychosocial effects of medical school. Importantly, grit, self-efficacy, and curiosity are protective factors against the negative psychosocial effects of medical school, whereas intolerance of uncertainty is a risk factor. Thus, research examining the associations among grit, self-efficacy, curiosity, and intolerance of uncertainty in first-generation college and first-generation medical students is needed. Methods We conducted a cross-sectional, descriptive study to assess medical students’ grit, self-efficacy, curiosity, and intolerance of uncertainty. We conducted independent samples t-tests and regression analyses using SPSS statistical software version 28.0. Results A total of 420 students participated in the study for a response rate of 51.5%. One-fifth of participants (21.2%, n = 89) identified as first-generation students, 38.6% (n = 162) participants reporting having a physician relative, and 16.2% (n = 68) reported having a physician parent. Grit, self-efficacy, and curiosity and exploration scores did not differ by first-generation college status, physician relative(s), or physician parent(s). However, total intolerance of uncertainty scores differed by physician relative(s) (t= -2.830, p = 0.005), but not by first-generation status, or physician parent(s). Further, subscale scores for prospective intolerance of uncertainty differed by physician relative(s) (t= -3.379, p = 0.001) and physician parent(s) (t= -2.077, p = 0.038), but not by first-generation college student status. In the hierarchical regression models, first-generation college student status and first-generation medical student status were not predictive of grit, self-efficacy, curiosity and exploration, or intolerance of uncertainty, although statistical trends were observed with students with physician relative(s) predicting lower intolerance of uncertainty scores (B= -2.171, t= -2138, p = 0.033) and lower prospective intolerance of uncertainty (B= -1.666, t= -2.689, p = 0.007). Conclusions These findings suggest that first-generation college students did not differ by grit, self-efficacy, curiosity, or intolerance of uncertainty. Similarly, first-generation medical students did not differ by grit, self-efficacy, or curiosity; however, first-generation medical students showed statistical trends in higher total intolerance of uncertainty and higher prospective intolerance of uncertainty. Additional research needs to confirm these findings in first-generation medical students
