Abstract
BACKGROUND Atrial fibrillation (AF) is common among patients in the intensive care unit (ICU) and can be triggered by severe illness or preexisting conditions. It is debated if AF is an independent predictor of poor outcome. METHODS Data derives from a single center retrospective registry including all patients with a stay on the medical ICU for >24 h. The primary endpoint was ICU survival. Secondary endpoints included receiving mechanical support (renal, respiratory or circulatory), hemodynamic parameters during AF, rate and rhythm control strategies, anticoagulation, and documentation. RESULTS A total of 616 patients (male gender 62.3%, median age 75 years) were included in our analysis. New-onset AF was diagnosed in 87 patients (14.1%), 136 (22.1%) presented with preexisting AF, and 393 (63.8%) did not develop AF. Initial episodes of new-onset AF exhibited higher hemodynamic instability than episodes in preexisting cases, with elevated heart rates and increased catecholamine doses (both p < 0.001). ICU survival in new-onset AF was 80.5% (70/87) compared to 92.4% (363/393) in patients without AF (OR 0.340, CI 0.182-0.658, p < 0.001). Likewise, ICU survival in preexisting AF was 86.8% (118/136) was significantly lower compared to no AF (OR 0.542, CI 0.290-0.986, p = 0.050*). Independent predictors of ICU survival for patients were atrial fibrillation (p = 0.016), resuscitation before or during ICU stay (p < 0.001), and receiving acute dialysis on ICU (p = 0.002). CONCLUSIONS ICU survival is noticeably lower in patients with new-onset or preexisting atrial fibrillation compared to those without. Patients who develop new-onset AF during their ICU stay warrant special attention for both short-term and long-term care strategies.

Abstract
BACKGROUND Radiotherapy delivery regimens can vary between a single fraction (SF) and multiple fractions (MF) given daily for up to several weeks depending on the location of the cancer or metastases. With limited evidence comparing fractionation regimens for oligometastases, there is support to explore toxicity levels to nearby organs at risk as a primary outcome while using SF and MF stereotactic ablative radiotherapy (SABR) as well as explore differences in patient-reported quality of life and experience. METHODS This study will randomize 598 patients in a 1:1 ratio between the standard arm (MF SABR) and the experimental arm (SF SABR). This trial is designed as two randomized controlled trials within one patient population for resource efficiency. The primary objective of the first randomization is to determine if SF SABR is non-inferior to MF SABR, with respect to healthcare provider (HCP)-reported grade 3-5 adverse events (AEs) that are related to SABR. Primary endpoint is toxicity while secondary endpoints include lesional control rate (LCR), and progression-free survival (PFS). The second randomization (BC Cancer sites only) will allocate participants to either complete quality of life (QoL) questionnaires only; or QoL questionnaires and a symptom-specific survey with symptom-guided HCP intervention. The primary objective of the second randomization is to determine if radiation-related symptom questionnaire-guided HCP intervention results in improved reported QoL as measured by the EuroQoL-5-dimensions-5levels (EQ-5D-5L) instrument. The primary endpoint is patient-reported QoL and secondary endpoints include: persistence/resolution of symptom reporting, QoL, intervention cost effectiveness, resource utilization, and overall survival. DISCUSSION This study will compare SF and MF SABR in the treatment of oligometastases and oligoprogression to determine if there is non-inferior toxicity for SF SABR in selected participants with 1-5 oligometastatic lesions. This study will also compare patient-reported QoL between participants who receive radiation-related symptom-guided HCP intervention and those who complete questionnaires alone.

Abstract
PURPOSE/OBJECTIVE(S) The purpose of this study was to investigate if there are differences in cancer incidence between immigrants and non-immigrants in Canada. We hypothesized that immigrants have lower cancer incidence compared to non-immigrants. MATERIALS/METHODS In this retrospective study, a linked-database approach was employed using Statistics Canada data. The Canadian Cancer Registry and Canadian Vital Statistics Database were linked with the 1991 Census cohort and the cohort was followed from 1992-2015 for cancer incidence. Excluded persons included Census non-respondents, institutional residents, those living on reserves and those less than 25 years of age. Sampling and bootstrap weights were used to ensure the sample represented the Canadian population and for statistical analyses. Total unweighted and weighted sample was 2,585,160 and 17,002,560, respectively which provided adequate power to answer the research question. Multivariate logistic regression and cox regression models included age, sex, household income, marital status, highest degree of education, knowledge of Canada's official languages (English or French), immigrant status and region of birth. Subcategories of immigrants were created based on time spent in Canada (0-4, 5-9, 10-19, 20+ years). RESULTS Raw data showed that 16.8% of immigrants and 15.9% of non-immigrants had cancer. After adjusting, logistic regression analyses showed that immigrants had lower odds of any cancer diagnoses in comparison with non-immigrants (OR = 0.92, 95% CI [0.92,0.93], p<.001), as well as lung (OR = 0.74, 95% CI [0.72-0.75], p<.001); breast (OR = 0.96, 95% CI [0.94-0.98], p = .001); colorectal (OR = 0.93, 95% CI [0.91-0.95], p<.001) and head and neck cancer (OR = 0.85, 95% CI [0.81-0.90], p<.001). However, immigrants had higher odds of stomach cancer and non-cervix gynecological cancers (OR = 1.39, 95% CI [1.32-1.46]; OR = 1.06, 95% CI [1.02-1.10]), respectively. Hazard ratios were lower for immigrants in comparison to the Canadian-born but increased based on time spent in Canada (0-4 years: 0.77, 95% CI [0.71-0.84], p<.001; 5-9 years: 0.82, 95% CI [0.75-0.89], p<.001; 10-19 years: 0.90, 95% CI [0.82-0.98], p = .011). CONCLUSION This study demonstrates a significant difference in cancer incidence between immigrants and non-immigrants. These results support current research in the observation of a 'healthy immigrant effect' (HIE) which convey that immigrants have better health outcomes than their native-born counterparts, with the effect decreasing over time spent in the host country. Since we controlled for demographic and socio-economic factors, we propose other factors to be contributing to the HIE such as individual-level health behaviors including smoking, diet and access to screening services. While it points to a HIE, we propose this phenomenon to be more complex due to the possibility of under-reporting of cases or differences in health behaviors, warranting further studies in this area.
