ABSTRACT

Importance: Intraductal papillary mucinous neoplasms (IPMNs) are pancreatic cysts that can give rise to pancreatic cancer (PC). Limited population data exist on their prevalence, natural history, or risk of malignant transformation (IPMN-PC). Objective: To fill knowledge gaps in epidemiology of IPMNs and associated PC risk by estimating population prevalence of IPMNs, associated PC risk, and proportion of IPMN-PC. Design, Setting, and Participants: : This retrospective cohort study was conducted in Olmsted County, Minnesota. Using the Rochester Epidemiology Project (REP), patients aged 50 years and older with abdominal computed tomography (CT) scans between 2000 and 2015 were randomly selected (CT cohort). All patients from the REP with PC between 2000 and 2019 were also selected (PC cohort). Data were analyzed from November 2021 through August 2023. Main outcomes and Measures: CIs for PC incidence estimates were calculated using exact methods with the Poisson distribution. Cox models were used to estimate age, sex, and stage-adjusted hazard ratios for time-to-event end points. Results: The CT cohort included 2114 patients (1140 females [53.9%]; mean [SD] age, 68.6 [12.1] years). IPMNs were identified in 231 patients (10.9%; 95% CI, 9.7%-12.3%), most of which were branch duct (210 branch-duct [90.9%], 16 main-duct [6.9%], and 5 mixed [2.2%] IPMNs). There were 5 Fukuoka high-risk (F-HR) IPMNs (2.2%), 39 worrisome (F-W) IPMNs (16.9%), and 187 negative (F-N) IPMNs (81.0%). After a median (IQR) follow-up of 12.0 (8.1-15.3) years, 4 patients developed PC (2 patients in F-HR and 2 patients in F-N groups). The PC incidence rate per 100 person years for F-HR IPMNs was 34.06 incidents (95% CI, 4.12-123.02 incidents) and not significantly different for patients with F-N IPMNs compared with patients without IPMNs (0.16 patients; 95% CI, 0.02-0.57 patients vs 0.11 patients; 95% CI, 0.06-0.17 patients; P = .62). The PC cohort included 320 patients (155 females [48.4%]; mean [SD] age, 72.0 [12.3] years), and 9.8% (95% CI, 7.0%-13.7%) had IPMN-PC. Compared with 284 patients with non-IPMN PC, 31 patients with IPMN-PC were older (mean [SD] age, 76.9 [9.2] vs 71.3 [12.5] years; P = .02) and more likely to undergo surgical resection (14 patients [45.2%] vs 60 patients [21.1%]; P = .003) and more-frequently had nonmetastatic PC at diagnosis (20 patients [64.5%] vs 130 patients [46.8%]; P = .047). Patients with IPMN-PC had better survival (adjusted hazard ratio, 0.62; 95% CI, 0.40-0.94; P = .03) than patients with non-IPMN PC. Conclusions and Relevance: In this study, CTs identified IPMNs in approximately 10% of patients aged 50 years or older. PC risk in patients with F-N IPMNs was low and not different compared with patients without IPMNs; approximately 10% of patients with PC had IPMN-PC, and they had better survival compared with patients with non-IPMN PC.

ABSTRACT

Background: Chronic illness is often comorbid with the psychological state of loneliness. Models of care for patients who experience chronic migraines may often lack an understanding of psychosocial influences of the illness. Addressing the effects of loneliness on the health behaviors of chronic migraine patients may further elucidate gaps in care that exist beyond the biomedical approach to migraine treatment. The primary aim of this study was to assess the relationship between loneliness and behavioral health decisions in chronic migraine patients, specifically patient ability to self-manage, and effectiveness of treatments. Methods: We conducted a cross-sectional survey among patients (n = 500) with migraine and assessed for the experience of loneliness by using the University of California, Los Angeles-Revised (UCLA-R) Three-item Loneliness Scale and the extent of migraine-related disability via the Migraine Disability Assessment (MIDAS). Furthermore, we evaluated patients for their ability to self-manage their migraines, and perceived effectiveness of treatment. Results: Nearly half of our population reported at least one measure of loneliness (230/500, 46.0%). Patients experiencing chronic migraine were statistically more likely to report feeling lonely when compared to patients with episodic migraines (P < .001). Patients who report loneliness had lower odds of feeling 'very satisfied" with their ability to self-manage their migraine symptoms (aOR = 0.34, 95% CI 0.14-0.81) and had lower odds of feeling "very satisfied" with their ability to avoid conditions that cause their headache (aOR = 0.39, 95% CI 0.16-0.91). Conclusions: Loneliness has significant effects on the illness experience of patients with chronic migraines, including their ability to self-manage or be satisfied with their current state of care. Psychosocial models of care that address loneliness among patients with chronic migraine may help improve health outcomes and management.
