1Multiphase computed tomography radiomics of pancreatic intraductal papillary mucinous neoplasms to predict malignancy显示文摘BACKGROUND Intraductal papillary mucinous neoplasms(IPMNs)are non-invasive pancreatic precursor lesions that can potentially develop into invasive pancreatic ductal adenocarcinoma.Currently,the International Consensus Guidelines(ICG)for IPMNs provides the basis for evaluating suspected IPMNs on computed tomography(CT)imaging.Despite using the ICG,it remains challenging to accurately predict whether IPMNs harbor high grade or invasive disease which would warrant surgical resection.A supplementary quantitative radiological tool,radiomics,may improve diagnostic accuracy of radiological evaluation of IPMNs.We hypothesized that using CT whole lesion radiomics features in conjunction with the ICG could improve the diagnostic accuracy of predicting IPMN histology.AIM To evaluate whole lesion CT radiomic analysis of IPMNs for predicting malignant histology compared to International Consensus Guidelines.METHODS Fifty-one subjects who had pancreatic surgical resection at our institution with histology demonstrating IPMN and available preoperative CT imaging were included in this retrospective cohort.Whole lesion semi-automated segmentation was performed on each preoperative CT using Healthmyne software(Healthmyne,Madison,WI).Thirty-nine relevant radiomic features were extracted from each lesion on each available contrast phase.Univariate analysis of the 39 radiomics features was performed for each contrast phase and values were compared between malignant and benign IPMN groups using logistic regression.Conventional quantitative and qualitative CT measurements were also compared between groups,viaχ2(categorical)and Mann Whitney U(continuous)variables.RESULTS Twenty-nine subjects(15 males,age 71±9 years)with high grade or invasive tumor histology comprised the'malignant'cohort,while 22 subjects(11 males,age 70±7 years)with low grade tumor histology were included in the'benign'cohort.Radiomic analysis showed 18/39 precontrast,19/39 arterial phase,and 21/39 venous phase features differentiated malignant from benign IPMNs(P<0.05).Multivariate analysis including only ICG criteria yielded two significant variables:thickened and enhancing cyst wall and enhancing mural nodule<5 mm with an AUC(95%CI)of 0.817(0.709-0.926).Multivariable post contrast radiomics achieved an AUC(95%CI)of 0.87(0.767-0.974)for a model including arterial phase radiomics features and 0.834(0.716-0.953)for a model including venous phase radiomics features.Combined multivariable model including conventional variables and arterial phase radiomics features achieved an AUC(95%CI)of 0.93(0.85-1.0)with a 5-fold cross validation AUC of 0.90.CONCLUSION Multi-phase CT radiomics evaluation could play a role in improving predictive capability in diagnosing malignancy in IPMNs.Future larger studies may help determine the clinical significance of our findings.Stuart L Polk Jung W Choi Melissa J McGettigan Trevor Rose Abraham Ahmed Jongphil Kim Kun Jiang Yoganand Balagurunathan Jin Qi Paola T Farah Alisha Rathi Jennifer B Permuth Daniel Jeong 2020World Journal of Gastroenterology2020,26,24:5

19Medication beliefs predict medication adherence in ambulatory patients with decompensated cirrhosis显示文摘AIM To investigate the impact of medication beliefs, illness perceptions and quality of life on medication adherence in people with decompensated cirrhosis.METHODS One hundred adults with decompensated cirrhosis completed a structured questionnaire when they attended for routine outpatient hepatology review. Measures of self-reported medication adherence(Morisky Medication Adherence Scale), beliefs surrounding medications(Beliefs about Medicines Questionnaire), perceptions of illness and medicines(Brief Illness Perception Questionnaire), and quality of life(Chronic Liver Disease Questionnaire) were examined. Clinical data were obtained via patient history and review of medical records. Least absolute shrinkage and selection operator and stepwise backwards regression techniques were used to construct the multivariable logistic regression model. Statistical significance was set at alpha = 0.05.RESULTS Medication adherence was ' High ' in 42 % o f participants, 'Medium' in 37%, and 'Low' in 21%. Compared to patients with 'High' adherence, those with 'Medium' or 'Low' adherence were more likely to report difficulty affording their medications(P < 0.001), lower perception of treatment helpfulness(P = 0.003) and stronger medication concerns relative to medication necessity beliefs(P = 0.003). People with 'Low' adherence also experienced greater symptom burden and poorer quality of life, including more frequent abdominal pain(P = 0.023), shortness of breath(P = 0.030), and emotional disturbances(P = 0.050). Multivariable analysis identified having stronger medication concerns relative to necessity beliefs(Necessity-Concerns Differential ≤ 5, OR = 3.66, 95%CI: 1.18-11.40) and more frequent shortness of breath(shortness of breath score ≤ 3, OR = 3.87,95%CI: 1.22-12.25) as independent predictors of 'Low'adherence.CONCLUSION The association between 'Low' adherence and patients having strong concerns or doubting the necessity or helpfulness of their medications should be explored further given the clinical relevance.Kelly L Hayward Patricia C Valery Jennifer H Martin Antara Karmakar Preya J Patel Leigh U Horsfall Caroline J Tallis Katherine A Stuart Penny L Wright David D Smith Katharine M Irvine Elizabeth E Powell W Neil Cottrell 2017World Journal of Gastroenterology2017,23,40:1
