Identifying palliative care needs in a Portuguese liver unit.

BACKGROUND & AIMS: Chronic liver disease is a major worldwide cause of morbidity and mortality. Palliative care policies are not clearly established in chronic liver disease. The NECPAL CCOMS-ICO© (NECesidades PALiativas/Palliative Needs) is a tool to identify palliative care needs, including a section for liver disease. AIM: The aim of this study was to identify palliative care needs in liver patients hospitalised in a tertiary referral Liver Unit. METHODS: Single-centre prospective observational study. One hundred and twenty patients with cirrhosis were included and NECPAL questionnaire was applied to all patients in a 7-month period. RESULTS: 84.2% of patients were considered as requiring palliative intervention; however, clinicians identified those needs only in 65.8% of the cases and caregivers in 6.7% of the cases; less than 8% of the patients were referred for palliative care consultation. An excessive use of healthcare resources (positive answer to question 3) was strongly associated with a positive need for palliative care (positive NECPAL): OR 7.305, CI 95% 2.54-20.995, P < .001). An excessive use of healthcare facilities has a sensitivity of 84.2% and a specificity of 42.1% for prediction of a positive NECPAL result (AUC 0.710, 95% CI 0.570-0.850, P = .004). CONCLUSIONS: The NECPAL CCOMS-ICO© represents a feasible and easy-to-use tool to identify palliative care needs in patients with chronic liver disease.

The use of a segmental endoscopic score may improve the prediction of clinical outcomes in acute severe ulcerative colitis.

BACKGROUND: Acute severe colitis (ASC) remains a challenging complication of ulcerative colitis. The early identification of patients who will not respond to optimal therapy is warranted. Increasing evidence suggests that endoscopy may play a role in predicting important outcomes in acute severe colitis. METHODS: The endoscopic activity of consecutive patients with acute severe colitis was evaluated using the Mayo endoscopic sub-score (Mayo) and the ulcerative colitis endoscopic index of severity (UCEIS). Two segmental indexes were also produced by summing the scores of the rectum and sigmoid (seg-Mayo and seg-UCEIS, respectively). Endpoints included the need for salvage therapy with infliximab or cyclosporine, refractoriness to corticosteroids, and colectomy. RESULTS: Of one hundred and eight patients enrolled in the study, 60 (55.6%) were male; with a median age of 34.5 years (range 15-80). All patients received intravenous steroids. Fifty-nine patients (55.6%) showed an incomplete or absent response to steroids, 35 patients (34.3%) received salvage therapy with infliximab or cyclosporine and 38 patients (33.3%) were colectomized during the index hospitalization or within the first year of follow-up. All scores were able to predict the need for surgery, but only the seg-UCEIS significantly predicted refractoriness to steroids. CONCLUSIONS: There was a strong correlation between endoscopic severity and unfavorable outcomes. The UCEIS outperformed the Mayo endoscopic sub-score in all important outcomes. Segmental scoring further improved the performance of the UCEIS.

HERVs establish a distinct molecular subtype in stage II/III colorectal cancer with poor outcome.

Colorectal cancer (CRC) is one of the most lethal malignancies. The extreme heterogeneity in survival rate is driving the need for new prognostic biomarkers. Human endogenous retroviruses (hERVs) have been suggested to influence tumor progression, oncogenesis and elicit an immune response. We examined multiple next-generation sequencing (NGS)-derived biomarkers in 114 CRC patients with paired whole-exome and whole-transcriptome sequencing (WES and WTS, respectively). First, we demonstrate that the median expression of hERVs can serve as a potential biomarker for prognosis, relapse, and resistance to chemotherapy in stage II and III CRC. We show that hERV expression and CD8+ tumor-infiltrating T-lymphocytes (TILs) synergistically stratify overall and relapse-free survival (OS and RFS): the median OS of the CD8-/hERV+ subgroup was 29.8 months compared with 37.5 months for other subgroups (HR = 4.4, log-rank P < 0.001). Combing NGS-based biomarkers (hERV/CD8 status) with clinicopathological factors provided a better prediction of patient survival compared to clinicopathological factors alone. Moreover, we explored the association between genomic and transcriptomic features of tumors with high hERV expression and establish this subtype as distinct from previously described consensus molecular subtypes of CRC. Overall, our results underscore a previously unknown role for hERVs in leading to a more aggressive subtype of CRC.

Serum vitamin D levels correlate with the presence and histological grading of colorectal adenomas in peri and postmenopausal women.

BACKGROUND & AIMS: Vitamin D is known to modulate immune function and proliferation. Higher vitamin D [25(OH)D3] serum levels have been reported to have protective effects on adenoma detection and colorectal cancer (CRC) development and survival. METHODS: This retrospective cohort study included 315 peri and post-menopausal women submitted to opportunistic colorectal and osteoporosis screening at the gynaecology outpatient clinic of a tertiary medical centre between 2004 and 2015. Colonoscopy findings were correlated with 25(OH)D3 and PTH serum levels, and subsequently adjusted in a multivariate logistic regression model. Confounding factors included demographic and colorectal risk factors, pharmacological therapies and bone densitometry metrics. RESULTS: A total of 77 lesions were identified in 66 patients. Vitamin D insufficiency (<30 ng/mL) and deficiency (<20 ng/mL) were identified in 79.4% and 35.2% of patients, respectively. In univariate analysis, lower levels of 25(OH)D3 were associated with polyp, adenoma and advanced adenoma detection. After adjusting for confounders, an association with polyps could not be observed, but a trend towards a negative correlation with adenoma detection was found (adjusted OR: 0.96; 95% CI 0.92-1.00; p = 0.083). Regarding advanced adenoma detection, 25(OH)D3 (adjusted OR: 0.86; 95% CI 0.77-0.97; p = 0.013) proved to be an independent predictive factor. No association was found between 25(OH)D3 levels and lesion detection site. CONCLUSION: The association of 25(OH)D3 serum levels with colorectal lesions seems to be restricted to adenomatous lesions and is influenced by histological grading. Vitamin D may be a valuable biomarker for optimization of risk stratification in group-specific CRC screening protocols.

Disagreement Among Gastroenterologists Using the Mayo and Rutgeerts Endoscopic Scores.

Background: Endoscopy is routinely performed in patients with inflammatory bowel disease to evaluate disease severity and guide important clinical decisions. However, variability in the interpretation of endoscopic findings can significantly impact patient management. Methods: Fifty-eight gastroenterologists were invited to participate in an online survey including pictures and video recordings of colonoscopies performed in patients with ulcerative colitis (UC) and Crohn's disease (CD). Participants were asked to rate the colorectal mucosa in patients with UC using the Mayo endoscopic subscore (MES), and the neo-terminal ileum and anastomosis in operated patients with CD using the Rutgeerts score (RS). Overall interrater agreement (IRA) and for several key end points was assessed using Krippendorff's alpha test. Results: The IRAs for the MES and RS were 0.47 (95% confidence interval [CI], 0.41-0.54) and 0.33 (95% CI, 0.28-0.38). The IRAs for UC mucosal healing (MES ≤ 1) and complete mucosal healing (MES = 0) were 0.57 (95% CI, 0.40-0.72) and 0.89 (95% CI, 0.73-1) and for CD postoperative recurrence (RS ≥ i2), and IRAs for severe postoperative recurrence (RS ≥ 3) were 0.44 (95% CI, 0.24-0.62) and 0.54 (95% CI, 0.36-0.71), respectively. Unexpectedly, although clinical information significantly influenced the IRA, participant expertise and consultation of scores did not produce significant changes in the IRA. Conclusions: A high rate of disagreement in endoscopic scoring was found in this study, even among experienced physicians. The variability in the assessment of mucosal healing and postoperative recurrence may translate into relevant differences in patient management.

Predicting short-term and long-term mortality of hospitalized Portuguese patients with alcoholic hepatitis.

BACKGROUND: Alcohol abuse can result in a spectrum of liver injury that ranges from mild fatty infiltration to alcoholic hepatitis (AH), cirrhosis, and hepatocellular carcinoma. The present study aimed to evaluate current scoring systems in predicting short-term and long-term mortality because of AH. PATIENTS AND METHODS: Records of 170 consecutive patients with AH admitted to a tertiary center between January 2005 and October 2015 were reviewed. Clinical and biochemical parameters were retrieved for the assessment of AH scores for the day of admission (D1) and for the seventh day of hospitalization (D7). Endpoints included admission to the ICU, and 30-day, 90-day, and 1-year mortality. RESULTS: The Maddrey discriminant function and the Model of End-Stage Liver Disease (MELD) were modest predictors of the need for ICU admission. In-hospital, 30-day, 90-day, and 1-year mortality were 15.9, 18.2, 21.8, and 30.0%, respectively. There was a numerical, albeit nonsignificant, trend for higher accuracy using D7 scores, especially the MELD, in predicting 30-day and 1-year mortality. Overall, all scores showed high negative predictive values (30 day: 91.2-98.7% and 1 year: 78.8-93.7%), but modest positive predictive values (30 day: 30.6-70.8% and 1 year: 42.1-61.2%). Survival rates were the highest among patients showing a decrease in the MELD, Glasgow Alcoholic Hepatitis Score, and Age, serum Bilirubin, International normalized ratio, and serum Creatinine score over the first week of admission. DISCUSSION: AH scores were comparable in identifying patients at low risk of mortality up to 1 year following admission. Reassessment of the MELD, Glasgow Alcoholic Hepatitis Score, and Age, serum Bilirubin, International normalized ratio, and serum Creatinine score scores after 1 week further improved mortality prediction.
