BACKGROUND Several risk scores have been developed to predict hepatocellular carcinoma (HCC) risk in chronic hepatitis B (CHB) patients. The majority of risk scores are based on pretreatment variables that are no longer considered risk factors for HCC development due to the suppression of hepatitis B virus replication early in the course of potent antiviral treatment in most patients. The PAGE-B score, which is based on platelet levels, age and sex, has been shown to accurately predict HCC risk in CHB patients on antiviral treatment in various populations. AIM We aimed to evaluate the PAGE-B score in predicting HCC risk in Turkish CHB patients on antiviral treatment. METHODS In this study, we recruited 742 CHB patients who had been treated with tenofovir disoproxil fumarate or entecavir for ≥ 1 year. Risk groups were determined according to the PAGE-B scores as follows: ≤ 9, low; 10-17, moderate and ≥ 18, high. The cumulative HCC incidences in each risk group were computed using Kaplan-Meier analysis and were compared using the log-rank test. The accuracy of the PAGE-B score in predicting HCC risk was evaluated using a time-dependent area under the receiver operating characteristic (AUROC) curve at all study time points. Univariate and multivariate logistic regression analyses were used to assess the risk factors for HCC development. RESULTS The mean follow-up time was 54.7 ± 1.2 mo. HCC was diagnosed in 26 patients (3.5%). The cumulative HCC incidences at 1, 3, 5 and 10 years were 0%, 0%, 0% and 0.4% in the PAGE-B low-risk group; 0%, 1.2%, 1.5% and 2.1% in the PAGE-B moderate-risk group; and 5%, 11.7%, 12.5%, and 15% in the PAGE-B high-risk group, respectively (log-rank P < 0.001). The AUROCs of the PAGE-B score in the prediction of HCC development at 1, 3, 5 and 10 years were 0.977, 0.903, 0.903 and 0.865, respectively. In the multivariable analysis, older age, male sex, lower platelet levels, presence of cirrhosis, and absence of alanine aminotransferase normalization at month 6 were associated with HCC development (all P < 0.05). CONCLUSION The PAGE-B score is a practical tool to predict HCC risk in Turkish patients with CHB and may be helpful to improve surveillance strategies.

Aim: Warfarin has a narrow therapeutic index. We aimed to evaluate the effect of frailty on compliance to warfarin pharmacotherapy and the attainment of international normalized ratio (INR) goals in patients aged over 65 years receiving warfarin. Material and Method: We recruited 473 elderly subjects aged 65 years and over. Indications for the administration of warfarin and INR values were recorded. All patients were assessed according to the Clinical Frailty Scale of the Canadian Health and Aging Study. Whether or not the target of INR values and the degree of frailty were compared. Results: Of the 473 patients, 401 patients were assigned to the non-frail group and 72 patients were assigned to the frail group. When patients were compared according to the attainment of target INR values, a negative correlation between frailty and numerical INR values was observed. Conclusion:It can be said that the presence of frailty negatively affects reaching the target INR values in patients over 65 years of age using warfarin. If patients in this population are indicated for warfarin use, it is necessary to be sure that INR monitoring will be done well.

This study aims to determine the factors that prolong cecal intubation time (CIT) and determine the effect of obesity on CIT measured using multiple indexes. MethodsPatients who underwent elective colonoscopy between July 10, 2020, and January 20, 2021, were evaluated in this prospective observational study. Age, gender, constipation, bowel preparation, presence of diverticulosis, previous surgery history, auxiliary maneuver and additional analgesic requirement, cecum intubation length (CL) and obesity indices [body mass index (BMI), waist circumference (WC), waist-toheight ratio (WHtR)] were analyzed. Factors affecting CIT were assessed by both univariate and multivariate logistic regression (LR) analyses. ResultsA total of 512 patients were analyzed. Mean CIT was 5.6 ± 1.6 min, and median CIT was 5.17 min. The CIT median was ≤5.17 min in 264 (51.5%) of the patients, and the CIT median was >5.17 min in 248 (48.5%). In the univariate LR results, young age, constipation, poor bowel preparation, increased CL, additional analgesic requirement, low WHtR, and low BMI (<25 kg/m2) were the factors that prolonged CIT (p <0.05). In the multivariate LR analysis results, WHtR >0.5 and BMI >30 kg/m2 were found to be independent factors that decrease CIT [OR: 0.01 (0.01 0.03) p <0.001; OR: 0.28 (0.13 0.57) p <0.001]. ConclusionYounger age, low WHtR, low BMI, increased CL, constipation, inadequate bowel preparation, and the use of extra analgesics were found to be associated with longer CIT. When all factors were evaluated together, obesity measured by only WHtR (>0.5) and BMI (>30 kg/m2) were the best predictors of decreased CIT.
