Higher trait optimism and/or lower cynical hostility are associated with healthier behaviors and lower risk of morbidity and mortality, yet their association with health care utilization has been understudied. Whether these psychological attitudes are associated with breast cancer screening behavior is unknown. To assess the association of optimism and cynical hostility with screening mammography in older women and whether sociodemographic factors acted as mediators of these relationships, we used Women's Health Initiative (WHI) observational cohort survey data linked to Medicare claims. The sample includes WHI participants without history of breast cancer who were enrolled in Medicare Parts A and B for ≥2 years from 2005-2010, and who completed WHI baseline attitudinal questionnaires (n = 48,291). We used survival modeling to examine whether screening frequency varied by psychological attitudes (measured at study baseline) after adjusting for sociodemographic characteristics, health conditions, and healthcare-related variables. Psychological attitudes included trait optimism (Life Orientation Test-Revised) and cynical hostility (Cook Medley subscale), which were self-reported at study baseline. Sociodemographic, health conditions, and healthcare variables were self-reported at baseline and updated through 2005 as available. Contrary to our hypotheses, repeated events survival models showed that women with the lowest optimism scores (i.e., more pessimistic tendencies) received 5% more frequent screenings after complete covariate adjustment (p < .01) compared to the most optimistic group, and showed no association between cynical hostility and frequency of screening mammograms. Sociodemographic factors did not appear to mediate the relationship between optimism and screenings. However, higher levels of education and higher levels of income were associated with more frequent screenings (both p < .01). We also found that results for optimism were primarily driven by women who were aged 75 or older after January 2009, when changes to clinical guidelines lead to uncertainty about risks and benefits of screening in this age group. The study demonstrated that lower optimism, higher education, and higher income were all associated with more frequent screening mammograms in this sample after repeated events survival modeling and covariate adjustment.

Immune-checkpoint inhibition (ICI) treatments improve outcomes for metastatic melanoma; however, > 60% of treated patients do not respond to ICI. Current biomarkers do not reliably explain ICI resistance. Given the link between ICI and autoimmunity, we investigated if genetic susceptibility to autoimmunity modulates ICI efficacy. In 436 patients with metastatic melanoma receiving single line ICI or combination treatment, we tested 25 SNPs, associated with > 2 autoimmune diseases in recent genome-wide association studies, for modulation of ICI efficacy. We found that rs17388568-a risk variant for allergy, colitis and type 1 diabetes-was associated with increased anti-PD-1 response, with significance surpassing multiple testing adjustments (OR 0.26; 95% CI 0.12-0.53; p = 0.0002). This variant maps to a locus of established immune-related genes: IL2 and IL21. Our study provides first evidence that autoimmune genetic susceptibility may modulate ICI efficacy, suggesting that systematic testing of autoimmune risk loci could reveal personalized biomarkers of ICI response.

Magnetic resonance imaging (MRI) now provides diagnostic assessment for numerous clinical indications, including lesion detection, characterization, functional assessment, and response to treatment. To maximize the potential to improve health through the use of MRI, it is critical to investigate the impact of MRI on outcomes, and to compare the effectiveness of MRI with existing standard diagnostic approaches. Outcomes of MRI can include survival but also intermediate steps such as potential reduction in unnecessary therapy, shorter time to the appropriate therapy, or shorter periods of hospital admission. To understand the effectiveness of an imaging test's sensitivity and specificity, the results' consequences are weighed, reflecting the disease type, severity, and treatment effects. In some instances, other modalities may be faster, more readily available, or less costly than MRI but additional disease-related information or better accuracy may translate to greater population level benefit. For health policy decisions and clinical guidelines, studies of comparative outcomes can lend depth to the strength of the evidence, the specific benefits vs. harms of using one test over another, and the most effective use of the test in terms of target population. Cost effectiveness then allows for a direct comparison of approaches in terms of the cost for the projected gain in life expectancy and/or quality adjusted life expectancy. Expanding the literature on improved efficiency, accessibility, clinical effectiveness, and cost effectiveness will support the directive for better quality and value in healthcare.

PURPOSE/OBJECTIVE:The National Comprehensive Cancer Network (NCCN) created guidelines to facilitate implementation of fertility preservation (FP) discussions and referrals for adolescent and young adult patients. We assessed if availability of workplace FP resources and referral policies differed among learners in the Educating Nurses about Reproductive Health in Cancer Healthcare (ENRICH) training program based on NCCN membership. METHODS:Learners completed a baseline application, including demographic information and the availability of FP resources and referral policies. Learners were categorized as either NCCN members or non-members and chi-square tests compared resources between the two groups. RESULTS:Learners from NCCN institutions reported the highest rates of established FP referral guidelines (p < .01), reproductive endocrinologist and infertility specialist (REI) on staff (p < .01), partnerships with REI, educational materials for staff (p < .05), and patients (p < .01). CONCLUSION/CONCLUSIONS:FP resources and referral policies were highest among learners from NCCN member institutions, but areas for development with fertility issues still exist and learners from non-member institutions may assist their workplaces in improving rates of discussions and referrals based on their ENRICH training. PRACTICE IMPLICATIONS/CONCLUSIONS:The variation of available resources and referral policies between groups suggests more FP education and training; focusing on implementation programs is needed to make steps towards impactful institutional level resources and policies.

Objectives/UNASSIGNED:Adult day health centers (ADHCs) serve >260,000 chronically ill individuals annually and are a preferred long-term care source for racial minorities, who also experience diet related disparities. Evidence regarding prevalence of nutritional risk is needed to inform dietary intervention planning in ADHCs. This study (1) identified prevalence of nutritional risk and associated factors, in a diverse sample of older ADHC users, (2) stratified differences in nutritional risk by race, and (3) explored associations between nutritional risk, chronic illness, and healthcare utilization. Methods/UNASSIGNED: < .05) differences among White Non-Hispanics, Blacks, Hispanics, and Asians aged >50. Bivariate chi-square tests were used to explore associations between nutritional risk and chronic disease, as well as healthcare utilization. Results/UNASSIGNED: = .01) were significant. Among blacks, 76.5% ate < 5 servings of fruits, vegetables, or milk daily, compared to 39.5% of whites; 21% of blacks ate <2 meals a day, compared to 2% of whites and Hispanics. Blacks (48.5%) more often reported involuntary weight loss/gain compared to whites (23.3%), and had the highest prevalence of tooth loss/mouth pain (41.2%) of any racial group. Conclusions/UNASSIGNED:Older adults in ADHCs are at elevated risk of malnutrition, and blacks disproportionately so. Routine nutritional screening in ADHCs should be considered, but customized population specific approaches are needed to address unique drivers of malnutrition risk.

Timely placement of an arteriovenous (AV) vascular access (native AV fistula [AVF] or prosthetic AV graft [AVG]) is necessary to limit the use of tunneled central venous catheters (TCVC) in patients with end-stage kidney disease (ESKD) treated with hemodialysis (HD). National guidelines recommend placement of AVF as the AV access of first choice in all patients to improve patient survival. The benefits of AVF over AVG are less certain in the older adults, as age-related biological changes independently modulate patient outcomes. This manuscript describes the rationale, study design and protocol for a randomized controlled pilot study of the feasibility and effects of AVG-first access placement in older adults with no prior AV access surgery. Fifty patients age ≥65 years, with incident ESKD on HD via TCVC or advanced kidney disease facing imminent HD initiation, and suitable upper extremity vasculature for initial placement of an AVF or AVG, will be randomly assigned to receive either an upper extremity AVG-first (intervention) or AVF-first (comparator) access. The study will establish feasibility of randomizing older adults to the two types of AV access surgery, evaluate relationships between measurements of preoperative physical function and vascular access development, compare vascular access outcomes between groups, and gather longitudinal assessments of upper extremity muscle strength, gait speed, performance of activities of daily living, and patient satisfaction with their vascular access and quality of life. Results will assist with the planning of a larger, multicenter trial assessing patient-centered outcomes.

Health literacy is an important issue to consider in the provision of health-care to children. Similar to the adult population, most parents face health literacy challenges. Of particular concern, 1 in 4 parents have low health literacy, greatly affecting their ability to use health information to make health decisions for their child. High expectations are placed on parents and children to achieve effective disease management and positive health outcomes in the context of complex health-care systems and disease treatment regimens. Low health literacy affects parent acquisition of knowledge, attitudes, and behaviors, as well as child health outcomes across the domains of disease prevention, acute illness care, and chronic illness care. The effect of low health literacy is wide ranging, including 1) poor nutrition knowledge and behaviors, 2) higher obesity rates, 3) more medication errors, 4) more emergency department use, and 5) poor asthma knowledge, behaviors, and outcomes. Health-care providers can mitigate the effects of health literacy by seeking to align health-care demands with the health literacy skills of families. Effective health literacy-informed interventions provide insights into methods that can be used by providers and health systems to improve health outcomes. Health literacy-informed communication strategies should be used with all families in a "universal precautions approach" because all parents likely benefit from clear communication. As scientific advances are made in disease prevention and management, unless families understand how to follow provider recommendations, the benefit of these advances will not be realized and disparities in outcomes will be exacerbated.

Sex tourism affects the sexual health of tourists and locals with whom they interact. However, a few studies have examined whether sex tourism is a risk factor for the acquisition of HIV and other sexually transmitted infections among men who have sex with men, and no such studies have been conducted in Western Europe. Almost 28% of our respondents reported engaging in sex tourism in their lifetime. Sex tourism was associated with an elevated risk of engagement in condomless receptive anal intercourse, use of alcohol/drugs during sex, participation in group sex, and an elevated risk of diagnosis with any type of sexually transmitted infection over the previous year, specifically gonorrhea and chlamydia. Research with men who have sex with men who engage in sex tourism should explore high-risk sexual behavior during sex tourism and also the feasibility and acceptability of the use of episodic pre-exposure prophylaxis for short periods of participation in elevated risk behaviors by tourists and local sex partners.
