Purpose This study aims to analyze undergraduate science majors’ perceptions of climate change. Design/methodology/approach Three science major student cohorts at Loyola Marymount University – first-year exposure (first-years taking a course related to climate science), first-year control (first-years taking a course unrelated to climate science) and non-first-year exposure (non-first-years interested in climate science taking a related course) – were given a climate literacy survey at the beginning and end of each course. Student perceptions were also compared with national and local data. Findings First-year students exposed to the topic showed increased awareness of climate change, trust in climate scientists and acknowledgment of the scientific consensus. Exposure also increased the non-first-year cohort’s awareness that global warming is already affecting the country. All three cohorts showed greater awareness of humanity’s role in causing climate change than the public. However, misconceptions regarding technical concepts persisted throughout. Research limitations/implications This was a single-institution study in Los Angeles with a limited sample. Exposure to specific topics varied between cohorts, depending on the learning outcomes of each course. Originality/value Undergraduate science majors have a greater understanding of climate change’s anthropogenic nature compared with local and national populations. First-year students have a lower initial understanding of climate change and less trust in climate scientists than non-first-year students interested in the topic. All science majors can improve their understanding of general concepts and strengthen their confidence in scientists by taking a relevant course. Students struggle to learn specific technical concepts, but can improve their short-term comprehension through studying.

Background Breast reconstruction (BR) has documented psychological benefits following mastectomy. Yet, racial/ethnic minority groups have lower reported rates of BR. We sought to evaluate the rate, type, and outcome of BR in a racially and ethnically diverse population within a safety-net hospital system. Methods All patients who underwent mastectomy between October 2015 and July 2019 at Harbor-UCLA Medical Center were retrospectively examined. Rates and type of BR were analyzed according to patient characteristics (race/ethnicity, age, and body mass index), smoking status, cancer stage, and presence of diabetes mellitus. Breast reconstruction outcomes were also assessed. Results Of the 259 patients that underwent mastectomy, 87 (33.6%) received BR. Immediate BR was performed in 79 (30.5%) patients and delayed BR in 8 (3.1%). Of the 79 patients with immediate BR, 58 (73.4%) received implant-based BR and 21 (26.5%) autologous tissue. The BR failure rate was 10%, all implant-based. Increasing age and smoking negatively impacted BR rates. Black ( P =.331) and Hispanic ( P =.132) ethnicity were not independent predictors of decreased breast reconstruction. Conclusion This study demonstrated that the rate, type, and quality of BR in this integrated safety-net hospital within a diverse population are comparable to national rates. When made available, historically underrepresented minority patients of Black and Hispanic ethnicity utilize BR.
