Abstract Background Patients with Crohn’s disease (CD) experience reduced quality of life (QoL), and disease-related impact on work productivity, contributing to a high disease burden. This study evaluated the association of achieving endoscopic outcomes at week 12 and associated QoL at week 52 in patients with CD treated with upadacitinib (UPA). Methods This post-hoc analysis evaluated data from two Phase 3 UPA induction (U-EXCEED and U-EXCEL) trials and one maintenance (U-ENDURE) trial in patients with moderate to severe CD. Patients who responded to 12-week induction therapy with UPA (45 mg per day [QD]) in U-EXCEED or U-EXCEL and received maintenance therapy with UPA (15 or 30 mg QD) up to 52 weeks in U-ENDURE were included. Meaningful improvement in QoL outcomes (Inflammatory Bowel Disease Questionnaire [IBDQ] remission ≥170, IBDQ response increase ≥16, Functional Assessment of Chronic Illness Therapy – Fatigue [FACIT-F] response increase ≥9, Short Form 36 [SF-36] Physical Component Score [PCS] and Mental Component Score [MCS] change ≥5, and Work Productivity and Activity Impairment Questionnaire [WPAI] change ≥7%) was evaluated at week 52 and compared between patients who achieved endoscopic response, endoscopic remission and ulcer-free endoscopy (absence of ulceration) at week 12 and those who did not using Chi-square test. Results Of 337 clinical responders included in the analyses, 152 (45.1%), 87 (25.8%), and 75 (22.2%) patients achieved endoscopic response, endoscopic remission, and ulcer-free endoscopy, respectively, at the end of induction. Significantly more patients who achieved an endoscopic response at end of induction (vs those who did not) attained a meaningful improvement in PROs by week 52 (IBDQ remission, 52.6% vs 30.3%; IBDQ response, 56.6% vs 36.8%; FACIT-F response, 46.7% vs 25.9%; SF-36 PCS 49.3% vs 30.8% and MCS 39.5% vs 25.9%; all P≤0.01, Table 1). Additionally, patients who achieved endoscopic response (vs those who did not) at the end of induction were more likely to attain meaningful improvement in WPAI overall work impairment by week 52 (47.1% vs 26.5%, P≤0.01, Table 1). Similar findings were observed in patients who achieved endoscopic remission (P≤0.01, Table 1) and ulcer-free endoscopy (P≤0.05, Table 1) vs those who did not at end of induction. Conclusion Achieving endoscopic outcomes at end of induction treatment was associated with meaningful improvement in quality of life and overall work productivity at 52 weeks for patients with CD receiving UPA. Endoscopic remission and ulcer-free endoscopy were associated with very similar long-term benefit.

61 Background: Although several guideline-recommended colorectal cancer (CRC) screening modalities have been shown to reduce CRC incidence and mortality, adherence remains below U.S. public health goals. Patient navigation services have been shown to improve CRC screening completion. Patient navigation services, including outbound phone, text, and e-mail reminders, and inbound phone support (>200 languages) are included with all mt-sDNA test (Cologuard) orders. A website and financial assistance (upon request and qualification) are also available for patients. We developed a survey, informed by behavioral theory, to identify psychosocial and communication factors associated with completion of mt-sDNA screening including questions to evaluate awareness and use of navigation services. Methods: Adults aged 45-75 years, with a US postal address, who received a valid order for mt-sDNA screening between 5/21-9/21 were eligible for sampling. RTI administered the survey between 3/22-6/22. Participants had the option to complete electronic- or paper-based surveys. We conducted crosstabulation with Chi Square to assess whether awareness and use of navigation services was significantly associated with (a) test completion within 6 months of the order date and (b) likelihood of future mt-sDNA use. Results: 2,973 participants completed the survey (RR= 21.7%; 65.15% by web and 34.85% by paper). Responders and non-responders did not differ significantly by age or sex. For each navigation service, awareness was significantly higher among those who completed the mt-sDNA test compared to those did not. Across all services, awareness was significantly higher among respondents reporting they were ‘very likely’ to complete mt-sDNA if recommended by a healthcare provider in the future than all other responses combined. A significantly higher proportion of completers (vs. non-completers) reported receiving the email reminder, using the Cologuard website, and using the English language inbound phone support. A significantly higher proportion of those “very likely” to complete mt-sDNA screening in the future reported receiving the email reminder, using the Cologuard website, and using the English language inbound phone support. Conclusions: Awareness and use of patient navigation services was associated with higher completion of the mt-sDNA test and with greater likelihood of future mt-sDNA test use. Patient navigation services comprised of evidence-based strategies, such as reminders, support patient adherence to CRC screening.

60 Background: Colorectal cancer (CRC) screening has been shown to reduce CRC incidence and mortality. Several CRC screening modalities are guideline recommended for average-risk adults aged 45-75 years. CRC screening is underutilized in the US and access to facility-based options, such as colonoscopy, represents a potential barrier. Home-based stool tests are guideline-endorsed and offer a convenient, accessible, scalable option for CRC screening. Thus, understanding the factors that influence completion of stool-based CRC screening is important to guide interventions to improve adherence. We developed a survey, informed by behavioral theory, to identify psychosocial, behavioral and communication factors associated with completion of mt-sDNA screening. Methods: The survey instrument was finalized through expert review, quality testing, and cognitive testing. Adults aged 45-75 years, with a US postal address, who received a valid order for mt-sDNA and whose kit was shipped between 5/21-9/21 were eligible for sampling. RTI administered the survey between 3/22-6/22. Participants had the option to complete electronic or paper surveys. We fit a multivariable logistic regression to identify factors significantly associated with mt-sDNA test completion. Results: Of 17,370 individuals invited to participate, 2,973 completed the survey (AAPOR RR3 = 21.7%); 77.3% of the sample completed the mt-sDNA test. Responders and non-responders did not differ significantly by sex or age. Controlling for demographic characteristics and insurance status, the odds of mt-sDNA test completion were significantly higher among participants who reported greater perceived test effectiveness (OR = 1.20), greater ease (OR = 4.06), and greater comfort in test use (OR = 1.18). Odds of test completion were significantly higher among participants who reported their healthcare provider discussed the mt-sDNA test with them (OR = 2.01) and involved them a great deal in decision making about CRC screening (OR = 1.29). Participants who expressed greater worry about developing CRC were less likely to return their mt-sDNA kit (OR = 0.81). Conclusions: To improve population adherence to CRC screening recommendations, efforts are needed to ensure patients understand the attributes and effectiveness of available test options and feel adequately prepared to complete their preferred screening test. Additionally, healthcare providers must be appropriately prepared and resourced to educate and to engage patients in shared decision-making about CRC screening.

Abstract Background We evaluated the health-related quality of life (HRQoL) benefits of upadacitinib (UPA) induction and maintenance treatment in a phase 3 study of patients with ulcerative colitis (UC) across a broad range of patient-centered outcomes. Methods Patients received UPA 45 mg once daily or placebo as induction treatment for 8 weeks. Patients who achieved clinical response were rerandomized to receive once daily UPA 15 mg, 30 mg, or placebo as maintenance treatment for 52 weeks. The percentages of patients reporting a clinically meaningful within-person change from baseline in the Ulcerative Colitis Symptoms Questionnaire, Inflammatory Bowel Disease Questionnaire, Work Productivity and Impairment Questionnaire, 36-Item Short Form Survey, and European Quality of Life-5 Dimension 5 Levels were evaluated at weeks 2 and 8 of induction and at weeks 0 and 52 of maintenance. Results Significant improvements from baseline in all HRQoL measures except the Work Productivity and Impairment Questionnaire–absenteeism were achieved with UPA (P < .001) vs placebo as early as week 2 of induction. These improvements were sustained at week 52 with significantly more patients treated with either 15 mg or 30 mg UPA vs placebo achieving meaningful within-person change in the Ulcerative Colitis Symptoms Questionnaire; Inflammatory Bowel Disease Questionnaire; overall work impairment, presenteeism, and activity impairment; both 36-Item Short Form Survey Physical and Mental Component Summaries; and European Quality of Life-5 Dimension 5 Levels (P < .001). Conclusions Induction treatment with UPA 45 mg significantly improved HRQoL measures. A significantly higher percentage of patients who responded to induction treatment with UPA maintained clinically meaningful improvements consistently across a wide range of HRQoL outcomes after 52 weeks of maintenance therapy with UPA (15 mg and 30 mg) compared with placebo.

Abstract Increased pancreatic cancer (PC) risk in first-degree relatives (FDRs) of PC patients with germline pathogenic/likely pathogenic variants (PLPV) is a motivator for cascade genetic testing. To date, unbiased FDR risk estimates for gene-specific risks of genetic cancer syndrome-associated cancers are unknown. These estimates would enhance genetic counseling of at-risk FDRs in families where the PC proband has been found to carry a PLPV. Study Aim: To objectively quantify gene-specific risks of six relevant cancers among FDRs of PC patients with germline PLPV in ATM, BRCA1, BRCA2, CDKN2A, MLH1, MSH2, MSH6, PALB2, and PMS2. Methods: In the prospective, clinic-based Mayo Clinic Biospecimen Resource for Pancreas Research registry, 4,562 PC patients had previously undergone germline genetic testing for pancreatic cancer-associated genes through either research studies or clinical testing. Of these, 234 PC probands were found to carry PLPV among 9 genes of interest and had provided detailed demographic and cancer data on their FDRs by questionnaire. We focused on six cancer types (ovary, breast, uterus, pancreas, colon, and malignant melanoma) in FDRs as reported by the probands. Standardized incidence ratios estimated risk by gene of six cancers among FDRs of PC patients carrying PLPV. Results: 1,670 FDRs (mean age 58.1+17.8SD; 48.9% female) were included in the study. We found significantly increased risk of ovarian cancer in female FDRs of PC probands who carry PLPV in BRCA1 (SIR 9.49, 95%CI:3.06-22.14) or BRCA2 (3.72, 95%CI:1.36-8.11), and breast cancer risks were higher with BRCA2 (2.62, 95%CI:1.89-3.54). Uterine cancer risk was increased in FDRs of PC probands who carry PLPV for Lynch Syndrome mismatch repair (MMR) (6.53, 95%CI:2.81-12.86). PC risk was also increased (ATM 4.53, 95% CI:2.69-7.16; BRCA2 3.45, 95%CI:1.72-6.17; CDKN2A 7.38, 95%CI:3.18-14.54; PALB2 5.39, 95%CI:1.45-13.79). Increased colon cancer risk was observed in FDRs of probands who carried MMR PLPV (5.83, 95%CI:3.70-8.75), while melanoma risk was elevated for FDRs of probands with CDKN2A PLPV (7.47, 95%CI:3.97-12.77). Conclusion: PLPV in nine syndrome-associated genes in PC probands are associated with increased risk of six cancers in FDRs in PC families. The findings underscore the importance of risk estimation of various other cancers in PC families for screening, early detection, and intervention. The gene-specific quantified cancer risks for FDRs of PC patients with syndrome-associated germline PLPV can inform counseling regarding extra-PC risks when considering cascade genetic testing.

Idiopathic pulmonary fibrosis (IPF) is a progressive lung disease with limited survival. Janus kinases (JAKs), tyrosine kinases that transduce cytokine-mediated signals, are known to be involved, but their specific roles in lung fibrosis are not well defined. In this study, the interactions between JAK1/signal transducers and activators of transcription (STAT)3 signaling and transforming growth factor-beta (TGF-β)-induced fibroblast responses were investigated using both pharmacological and siRNA approaches in human normal and IPF-derived lung fibroblasts. We found that JAK1 directly interacts with the TGF-β receptor I subunit (TβRI), and silencing JAK1 promotes myofibroblast transdifferentiation. However, the suppression of JAK1 signaling in vitro and in vivo using an inhibitor (upadacitinib) did not alter lung fibroblast activation or fibrosis development. STAT3 was constitutively active in cultured primary lung fibroblasts; this STAT3 activation required JAK1 and repressed myofibroblast transdifferentiation. Loss of phosphorylated STAT3 following transcriptional JAK1 silencing promoted myofibroblast transdifferentiation. In contrast, transcriptional silencing of unphosphorylated STAT3 suppressed TGF-β signaling, decreased SMAD3 activation, and reduced myofibroblast transdifferentiation and ECM production. Taken together, these observations support a role for JAK1/STAT3 as a direct regulator of TGF-β signaling in lung fibroblasts. Modulation of JAK1/STAT3 signaling in lung fibroblasts represents a noncanonical approach to regulating TGF-β-induced fibrosis and suggests the potential for a novel approach to treat pulmonary fibrosis.

Background and Aim: The etiology of liver diseases has changed in recent years, but its impact on the comparative burden of liver cancer between males and females is unclear. We estimated sex differences in the burden of liver cancer across 204 countries and territories from 2010 to 2019. Approach and Result: We analyzed temporal trends in the burden of liver cancer using the methodology framework of the 2019 Global Burden of Disease study. We estimated annual frequencies and age‐standardized rates (ASRs) of liver cancer incidence, death, and disability‐adjusted life‐years (DALYs) by sex, country, region, and etiology of liver disease. Globally in 2019, the frequency of incident cases, deaths, and DALYs due to liver cancer were 376,483, 333,672, and 9,048,723 in males, versus 157,881, 150,904, and 3,479,699 in females. From 2010 to 2019, the incidence ASRs in males increased while death and DALY ASRs remained stable; incidence, death, and DALY ASRs in females decreased. Death ASRs for both sexes increased only in the Americas and remained stable or declined in remaining regions. In 2019, hepatitis B was the leading cause of liver cancer death in males, and hepatitis C in females. From 2010 to 2019, NASH had the fastest growing death ASRs in males and females. The ratio of female‐to‐male death ASRs in 2019 was lowest in hepatitis B (0.2) and highest in NASH (0.9). Conclusions: The overall burden of liver cancer is higher in males, although incidence and death ASRs from NASH‐associated liver cancer in females approach that of males.

Peripheral arterial and venous examinations are performed regularly in vascular labs and interpreted by physicians of different specialities. Many vascular examinations have nonvascular pathology that is either inadvertently imaged by the sonographer or imaged with intent as it relates to patient's symptoms. It is prudent for every reader of vascular studies to be acquainted with the sonographic appearance of these non‐vascular lesions to enable appropriate and optimal interpretation that has a direct bearing on patient's clinical care. Our review includes a discussion of the nonvascular pathologies like lymph nodes, soft tissue edema, soft tissue fluid collections, musculotendinous injuries, soft tissue masses, and joint and bursal pathologies that may be encountered during interpretation of vascular exams. The pictorial essay includes a discussion of their sonographic appearances and pitfalls in interpretation. Multiple illustrative examples and sonographic images of the non‐vascular pathologies found during interpretation of vascular studies have been utilized to highlight their appearances.

Background: Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease globally in tandem with the growing obesity epidemic. However, there is a lack of data on the relationship between historical weight changes 10 years ago and at present on NAFLD prevalence at the population level. Therefore, we sought to evaluate the relationship between weight classes and the prevalence of NAFLD. Methods: Data were used from the United States National Health and Nutrition Examination Survey (NHANES) from 1999 to 2018. Univariate and multivariate general linear model analyses were used to obtain risk ratio (RR) estimations of NAFLD events. Results: In total, 34,486 individuals were analysed, with those who were lean at both time points as the control group. Overweight (RR: 14.73, 95%CI: 11.94 to 18.18, p < 0.01) or obese (RR: 31.51, 95%CI: 25.30 to 39.25, p < 0.01) individuals at both timepoints were more likely to develop NAFLD. Residual risk exists where previously obese individuals became overweight (RR: 14.72, 95%CI: 12.36 to 17.52, p < 0.01) or lean (RR: 2.46, 95%CI: 1.40 to 4.31, p = 0.02), and previously overweight individuals who became lean (RR 2.24, 95%CI 1.42 to 3.54, p = 0.01) had persistent elevated risk of developing NAFLD despite weight regression. Sensitivity analysis identified that a higher proportion of individuals with regression in weight class were diabetics and Mexican Americans, while fewer African Americans saw weight-class regression. Conclusions: Residual risk exists in patients who lost weight despite the smaller magnitude of effect, and targeted weight reductions should still be used to mitigate the risk of NAFLD at the population level.
