AbstractIntroductionSmoking commercial tobacco products is highly prevalent in American Indian and Alaska Native (Indigenous) pregnancies. This disparity directly contributes to maternal and fetal mortality. Our objective was to describe cigarette smoking prevalence, cessation intervention uptake, and cessation behaviors of pregnant Indigenous people compared to sex and age-matched regional cohort.Aims and MethodsPregnancies from an Indigenous cohort in Olmsted County, Minnesota, identified in the Rochester Epidemiology Project, were compared to pregnancies identified in a sex and age-matched non-Indigenous cohort from 2006 to 2019. Smoking status was defined as current, former, or never. All pregnancies were reviewed to identify cessation interventions and cessation events. The primary outcome was smoking prevalence during pregnancy, with secondary outcomes measuring uptake of smoking cessation interventions and cessation.ResultsThe Indigenous cohort included 57 people with 81 pregnancies, compared to 226 non-Indigenous people with 358 pregnancies. Smoking was identified during 45.7% of Indigenous pregnancies versus 11.2% of non-Indigenous pregnancies (RR: 3.25, 95% CI = 1.98–5.31, p ≤ .0001). Although there was no difference in uptake of cessation interventions between cohorts, smoking cessation was significantly less likely during Indigenous pregnancies compared to non-Indigenous pregnancies (OR: 0.23, 95% CI = 0.07–0.72, p = .012).ConclusionsIndigenous pregnant people in Olmsted County, Minnesota were more than three times as likely to smoke cigarettes during pregnancy compared to the non-indigenous cohort. Despite equivalent uptake of cessation interventions, Indigenous people were less likely to quit than non-Indigenous people. Understanding why conventional smoking cessation interventions were ineffective at promoting cessation during pregnancy among Indigenous women warrants further study.ImplicationsIndigenous pregnant people in Olmsted County, Minnesota, were greater than three times more likely to smoke during pregnancy compared to a regional age matched non-Indigenous cohort. Although Indigenous and non-Indigenous pregnant people had equivalent uptake of cessation interventions offered during pregnancy, Indigenous people were significantly less likely to quit smoking before fetal delivery. This disparity in the effectiveness of standard of care interventions highlights the need for further study to understand barriers to cessation in pregnant Indigenous people.

AbstractBackgroundResilience represents the capacity to adapt to adversity. Resilience can improve following behavioral interventions. We examined lung transplant candidates’ resilience as a novel predictor using the Connor‐Davidson Resilience Scale (RISC‐10).MethodsWaitlisted candidates at six centers were mailed questionnaires from 9/16/2015 to 10/1/2019. Follow‐up surveys were collected annually and post‐transplant. Outcomes were recorded through February 17, 2020. Primary outcome was pre‐transplant death/delisting. Analyses included t test or chi‐square for group comparisons, Pearson's correlation coefficients for strength of relationships, and Cox proportional‐hazard models to evaluate associations with outcomes, adjusting for age, sex, and mood.ResultsParticipation was 55.3% (N = 199). Baseline RISC‐10 averaged 32.0 ± 5.6 and did not differ by demographics, primary transplant diagnosis, or disease severity markers. RISC‐10 did not correlate to the commonly utilized Psychosocial Assessment of Candidates for Transplant [PACT] or Stanford Integrated Psychosocial Assessment for Transplantation [SIPAT] tools. Scores < 26.3 (representing > 1 standard deviation below population average) occurred in 16% and were associated with pre‐transplant death or delisting, adjusted Hazard Ratio of 2.60 (95% Confidence Interval 1.23‐5.77; P = .01).ConclusionOne in six lung candidates had low resilience, predicting increased pre‐transplant death/delisting. RISC‐10 did not correlate with PACT or SIPAT; resilience may represent a novel risk factor.

Purpose: To identify the visual acuity outcomes of patients with age-related macular degeneration treated with intravitreal anti–vascular endothelial growth factor injections over a 10-year period. Methods: This was a retrospective, cohort study of eyes with exudative age-related macular degeneration that received ≥2 intravitreal anti–vascular endothelial growth factor injections and had at least 10 years of follow-up after the initiation of treatment. Snellen visual acuity was recorded at baseline and then annually until the last year of follow-up. Optical coherence tomography data were collected at the time of treatment initiation and at the last examination visit. A subanalysis was performed on patients who continued to receive anti–vascular endothelial growth factor therapy using a modified treat and extend protocol versus those who discontinued treatment for longer than 1 year. Results: One hundred thirty eyes of 115 patients met the inclusion criteria. The mean follow-up after treatment initiation was 11.1 ± 0.7 years. Eyes received an average of 45.1 ± 32.3 intravitreal injections in total and a mean of 5 to 7 injections per year. The baseline mean logMAR visual acuity was 0.61 ± 0.5 (Snellen acuity 20/81), and the final mean logMAR visual acuity was 0.88 ± 0.7 (20/152, P value = <0.0001). There were 40 eyes that received at least one injection every year. These eyes did not have a significant change in visual acuity between the baseline and final examinations 0.47 ± 0.4 (20/59 vs. 0.58 ± 0.5 [20/76, P = 0.28]), whereas the eyes that did not receive at least one injection every year saw a significant decline in visual acuity 0.67 ± 0.5 (20/94 vs. 1.01 ± 0.7 [20/205, P < 0.0001]). Conclusion: Eyes with exudative age-related macular degeneration that received intravitreal injections every year had stable visual acuity over a 10-year period. Continuous intravitreal anti–vascular endothelial growth factor therapy may stabilize visual acuity for 10 years and potentially longer.
