To examine incidence trends and patterns for early- late-onset liver cancer. Liver intrahepatic bile duct (IBD) cancers diagnosed between 2000 2019 were acquired from 22 SEER registries. Variables included early-onset (20-49) vs. (50+), anatomic subsite, histologic type (hepatocellular carcinoma [HCC] IBD cholangiocarcinoma [ICC]), sex, race/ethnicity. Age-standardized rates calculated using SEER*Stat. Jointpoint regression analysis was employed to estimate the annual percent change (APC)...
Objectives. To identify factors associated with persistent COVID-19 vaccine refusal among Nebraska residents 6 months after an initial diagnosis. Methods. Using case investigation surveillance data and vaccination records from the Department of Health Human Services, a cohort 16 344 unvaccinated, COVID-19‒confirmed individuals (May 2021‒February 2023) were asked for their reason nonvaccination (RNV), then followed to assess subsequent status. We used modified Poisson regression estimate risk...
Delayed medical care may result in adverse health outcomes and increased cost. Our purpose was to identify factors associated with delayed a primarily rural state.Using stratified random sample of 5,300 Nebraska households, we conducted cross-sectional mailed survey online response option (27 October 2020 8 March 2021) English Spanish. Multiple logistic regression models calculated adjusted odds ratios (aOR) 95% confidence intervals.The overall rate 20.8% (n = 1,101). Approximately 37.8%...
Debate exists regarding the role of robotic-assisted surgery in colorectal cancer. Robotic-assisted has been promoted as a strategy to increase availability minimally invasive surgery, which is associated with improved short-term morbidity; however, much more expensive than laparoscopic surgery.We aimed understand hospital and patient trends adoption surgery.The study used cross-sectional longitudinal designs.The included 2010 2012 American Hospital Association surveys, well 2010-2012...
Background Liver cancer incidence increased in the US from 1975 through 2015 with heterogeneous rates across subpopulations. Upstream or distal area-level factors impact liver risks. Objective The aim of this study was to examine association between deprivation and hepatocellular carcinoma (HCC) survival. We also explored area treatment modalities. Methods Louisiana Tumor Registry identified 4,151 adult patients diagnosed malignant HCC 2011 2020 linked residential address census tract...
Abstract Purpose Rural (vs urban) patients experience poorer cancer outcomes and are less likely to be engaged in prevention, such as screening. As part of a community needs assessment, we explored rural survivors’ caregivers’ experiences, perceptions, attitudes toward care services. Methods We conducted 3 focus groups (N = 20) Spring 2021 Nebraska. Findings Three patterns diagnosis were regular care/screening without noticeable symptoms, treatment for symptoms not initially identified...
It is unclear whether emerging synthetic tobacco-free nicotine superiority messages such as 'better flavor and better experience' 'no residual impurities of tobacco-derived nicotine' may impact consumer perception product choice between vaping products.
Surgical resection is the primary treatment for colon cancer, but use of laparoscopic approaches varies widely despite demonstrated short- and long-term benefits.The purpose this study was to identify characteristics associated with cancer quantify variation based on patient, hospital, geographic characteristics.Bayesian cross-classified, multilevel logistic models calculated adjusted ORs CIs surgeon, unexplained variability (predicted vs. observed values) using median odds ratios hospitals...
To examine predictors of flu vaccination and intention among college freshmen during a nonpandemic influenza season using the health belief model (HBM).A total 184 at single institution participated in mixed-mode (paper or online) survey October-November 2015.Flu to vaccinate were predicted binomial logistic regression on HBM constructs (perceived susceptibility, severity, benefits, barriers, cues action, availability), prior history, family peer reference behaviors, demographics.Overall,...
Radon is the second leading cause of lung cancer, but exposure can be reduced through testing one's home and mitigating if levels are high.To determine what factors predict radon to identify, spatial analysis, areas in Illinois with lower or higher than expected rates.An ecological study design was used evaluate data on tests performed by a licensed professional test kit analyzed state-approved laboratory between 2005 2012. Zip code-level rates per 1000 occupied residences were calculated...
Abstract Community outreach and engagement (COE) activities are important in identifying catchment area needs, communicating these facilitating relevant to the population. The National Cancer Institute–designated cancer centers required conduct catchment-wide needs assessments as part of their COE activities. University Nebraska Medical Center Buffett undertook a three-year-long process assessment, identify priorities, develop workgroups implement prevention control Activities were conducted...
Abstract Background Healthcare accessibility and utilization are important social determinants of health. Lack access to healthcare, including missed or no-show appointments, can have negative health effects be costly patients providers. Various office-based approaches community partnerships address patient barriers. Objectives (1) To understand provider perceptions barriers; (2) describe the policies practices used late (3) evaluate support services, both in-clinic with partners. Methods...
Objective: To investigate trends of motorcyclist fatalities and identify at-risk populations by demographics crash characteristics. Methods: We used the Fatality Analysis Reporting System (FARS) database (2000-2016) to track fatality rate trends, which were quantified using Poisson mixed-effects regression models comparing 2000-2001 2007-2008, as well 2009-2010 2015-2016. Results: The overall per 100,000 population increased from 2000 2016, defined two trend lines-before after economic...
Patients with (versus without) diabetes mellitus who develop colon cancer are at increased risk of dying within 30 days after surgery.The purpose this study was to identify potential mediators the effect on all-cause 30-day mortality surgery for cancer.A retrospective cohort conducted using 2013-2015 National Surgical Quality Improvement Program data.The various hospitals across United States (from 435 603 hospitals).Patients underwent resection or without obstruction based colectomy module...
Federal reporting of crash fatalities has limited age-by-sex stratification, but both age and sex are associated with driving reduction cessation. We described older driver fatal involvement using Fatality Analysis Reporting System data to calculate rates (per 100,000 licensed drivers, per population) stratifications. Nationally from 2000 through 2017, 110,422 drivers 65+ were involved in crashes resulting at least one death within 30 days, 67,843 these died. Involvement fatality 2017 lowest...
