RESUMO

BACKGROUND: The percentage of and factors associated with the regression of Barrett's esophagus (BE) or its characteristic intestinal metaplasia (IM) remain unclear, and conflicting results have been reported because of diverse regression and sampling error definitions. Thus, we investigated the rates of IM regression, sampling error, and associated factors. METHODS: Forty-two patients with proven short-segment BE with IM who underwent two follow-up endoscopies with biopsies of Barrett's mucosa were retrospectively analyzed. Additional Alcian blue and MUC2 staining were done on the biopsy specimens without IM in hematoxylin-eosin staining. Only patients with negative hematoxylin-eosin, Alcian blue, and MUC2 staining for IM in both follow-up endoscopies were considered to have true regression. When all three stains were negative for IM in the first, but positive in the second follow-up endoscopy, we considered IM persisting and declared sampling error. RESULTS: Among the 18 patients without IM at the first follow-up endoscopy, only five (11.9%) were judged to have true regression. Prolonged proton-pump inhibitor use was significantly associated with regression. Limited experience of the endoscopist, and insufficient biopsy number were significantly related to sampling error. Receiver operating characteristic (ROC) curve analysis showed the best cut-off value of the biopsy number/maximal-length (cm) ratio to predict sampling error was 2.25. CONCLUSION: In our patients with short-segment BE, 11.9% experienced regression of IM. Prolonged proton-pump inhibitors treatment was associated with regression. An insufficient biopsy number was related to a missed IM, which may be eliminated by maintaining biopsy number/maximal-length (cm) ratio ≥2.25.

RESUMO

BACKGROUND: Coronary artery calcification (CAC) burden assessed by Agatston score (AS) is currently recommended to stratify patients at risk for future acute coronary syndrome (ACS). Besides the CAC burden, the biostructure of CAC may also play a vital role in the vulnerability of CAC, which CT radiomics could reveal. Propensity-score matching of the traditional risk factors and CAC burden between the ACS and asymptomatic groups could radically remove biases and allow the exploration of characteristic features of CAC in ACS. METHODS: We retrospectively identified 77 patients with ACS who had a CAC scan before percutaneous coronary intervention between 2016 and 2019. These 77 patients were one-to-two propensity-score matched for traditional risk factors of ACS and AS ranks to select 154 subjects from 2890 asymptomatic subjects. A validation cohort of 30 subjects was also enrolled. Radiomics features of each plaque were extracted and averaged in each person. Conditional logistic regression and area-under-curve analysis were used for statistical analysis. RESULTS: A higher number of coronary segments involved, lower mean, median, first quartile, and standard deviation of attenuation, and increased kurtosis of attenuation of CAC were associated with the ACS group compared to the control group (p < 0.05 for all). Multivariable analysis showed that the lower median attenuation (OR = 0.969, p < 0.001) and higher Kurtosis (OR = 18.7, p < 0.001) were associated with the ACS group. The median attenuation and kurtosis significantly increase across AS ranks 1 to 4 (p = 0.001). The AUC of kurtosis (0.727) and median attenuation (0.66) were both significantly higher than that of the standard AS (AUC = 0.502) and the number of TRF (AUC = 0.537). The best cut-off of kurtosis at 2.74 yielded an accuracy of 74%, and the cut-off of median attenuation at 196 yielded an accuracy of 68%. The accuracy of kurtosis was 64%, and the accuracy of median attenuation was 55% in the validation cohort. CONCLUSION: After propensity-matching traditional risk factors and CAC burden, CT radiomics highlighted that lower median attenuation and higher kurtosis were the CAC characteristics of vulnerable plaques. These features improve the understanding of the biomechanics of CAC evolution and enhance the value of CAC scan in ACS risk assessment.

RESUMO

PURPOSE: Psychological and social support are crucial in treating cancer. Cancer resource centers provide patients with cancer and their families with services that can help them through cancer treatment, ensure that patients receive adequate treatment, and reduce cancer-related stress. These centers offer various services, including medical guidance, health education, emotional assistance (e.g., consultations for cancer care), and access to resources such as financial aid and post recovery programs. In this study, we comprehensively analyzed how cancer resource centers assist patients with cancer and improve their clinical outcomes. METHODS: The study participants comprised patients initially diagnosed with head and neck cancer or esophageal cancer. A total of 2442 patients from a medical center in Taiwan were included in the study. Data were analyzed through logistic regression and Cox proportional hazards regression. RESULTS: The results indicate that unemployment, blue-collar work, and a lower education level were associated with higher utilization of cancer resource center services. The patients who were unemployed or engaged in blue-collar work had higher risks of mortality than did their white-collar counterparts. Patient education programs can significantly improve the survival probability of patients with cancer. On the basis of our evaluation of the utilization and benefits of services provided by cancer resource centers, we offer recommendations for improving the functioning of support systems for patients with cancer and provide suggestions for relevant future research. CONCLUSIONS: We conclude that cancer resource centers provide substantial support for patients of low socioeconomic status and improve patients' survival.

RESUMO

BACKGROUND: Trend pattern analysis are lacking for hepatitis B surface antigen (HBsAg) kinetics in chronic hepatitis B (CHB) patients during nucleos(t)ide analogue (Nuc) therapy. We evaluated the trend patterns of HBsAg kinetics by time series analysis and forecasting times to HBsAg seroclearance accordingly. METHODS: A total of 116 CHB patients with documented three-month HBsAg levels during the previous more than five years of Nuc therapy were included. The piecewise linear trends of the autoregressive-moving average (ARMA) model were used for time series analysis of HBsAg kinetics trends. Best fitted models were created for each patient using HBsAg datasets with backtracking capability. Predicted time to HBsAg seroclearance was calculated accordingly. RESULTS: Four trend patterns of HBsAg kinetics were found: no trend (n = 22, 19.0%), single trend (n = 16, 13.8%), biphasic trend with rapid-slow decline (n = 56, 48.2%) and biphasic trend with rise-decline (n = 22, 19.0%). Except for no-trend patients, the trend became slow reduction as HBsAg declined. Only 6.1% of patients continued rapid decline when the initial HBsAg of the last trend reached <100 IU/mL. Last trend slopes < -10 and rise-decline patterns indicate greater chances of achieving HBsAg seroclearance within two years. CONCLUSION: Best fitted ARMA models of HBsAg kinetics can be created individually for patients during Nuc therapy. About 67.2% patients have biphasic trend patterns, suggesting the dynamic nature of HBsAg kinetics over time. Trend patterns and last trend slopes predict individual times to HBsAg seroclearance.

RESUMO

BACKGROUND: Colorectal ESD is difficult because of the poor maneuverability and difficulty of mucosal flap creation. Diving, Lifting and Horizontal (DLH) dissection technique and loop-clip traction are two different methods to facilitate mucosal trimming and adequate mucosal flap creation. We combined the advantages of these two techniques (DLH+T) in our daily practice colorectal ESD since July 2020. OBJECTIVE: The purpose of this study was to examine the outcomes of DLH+T dissection compared with the conventional dissection. METHODS: We retrospectively reviewed the clinical using DLH+T dissection compared with the conventional dissection since January 2018 at a single tertiary care institution. Postoperative short-term outcomes were investigated after the procedure including mucosal flap creation time, dissection time, dissection speed, en bloc resection rate, and perioperative complications. RESULTS: 28 lesions were in DLH+T dissection group and 39 lesions in the conventional dissection group. The outcomes including en bloc resection rate, dissection speed, and complication between the two groups were similar. The mean mucosal flap creation time (p = 0.035) and the mean dissection speed (p = 0.041) of the DLH+T dissection group was significantly shorter and faster. CONCLUSION: DLH dissection followed by loop-clip traction (DLH+T) technique is a useful technique for safe, efficient, and adequate mucosal flap creation, which can increase the dissection speed and may prevent complication, especially in biopsy-related submucosal fibrosis.

RESUMO

PURPOSE: The sessile serrated adenoma/polyp detection rate (SSA/PDR) among different colonoscopy indications from daily practice has not been fully understood. This study aimed to evaluate the detection and clinical characteristics of serrated polyps and conventional adenomas between outpatient department (OPD) and physical checkup unit (PCU) patients receiving colonoscopy. METHODS: The data for this retrospective study were collected between 2016 and 2017 at Kaohsiung Veterans General Hospital in Taiwan. A total of 7047 individuals were included, and information on polyp and adenoma detection was extracted from the colonoscopy reports. RESULTS: The adenoma detection rate, the SSA/PDR, and the detection rate of traditional serrated adenoma (TSA) were 32.2%, 0.60%, and 0.50%, respectively. Risk analysis revealed no significant difference (p = 0.095) in SSA/PDR between individuals < 50 years and ≥ 50 years, and no trend of increased SSA/PDR as age increased was observed (p = 0.320). SSA/P and TSA had higher risks for synchronous advanced neoplasia than conventional adenoma, but with proximal hyperplastic polyps lower (p < 0.001, respectively). No significant difference of SSA/PDR between OPD and PCU patients was observed (p = 1.000); however, the age of SSA/P was significantly older in OPD than in PCU patients (p = 0.048). CONCLUSION: The detection rates of CA and TSA were associated with age groups; however, SSA/PDR was insignificantly higher among individuals aged < 50 years than those with other age groups. In addition, SSA/PDR between OPD and PCU patients was not significantly found in daily practice of colonoscopies.

RESUMO

BACKGROUND: In patients with common bile duct stones (CBDS) and intact gallbladder, further management for the gallbladder after the CBDS clearance is still controversial. The relationship between gallbladder motility and the biliary complications were seldom discussed. Our study is to predict the subsequent biliary complications by gallbladder function test using fatty meal sonography (FMS) in patients with CBDS who had been treated by endoscopic retrograde cholangiopancreatography (ERCP). METHODS: Patients with an intact gallbladder and CBDS after endoscopic clearance of bile duct were enrolled. Patients received a fatty meal sonography after liver function returned to normal. The fasting volume, residual volume, and gallbladder ejection fraction (GBEF) in FMS were measured. Relationships of patients' characteristics, gallbladder function and recurrent biliary complication were analyzed. RESULTS: From 2011 to 2014, 118 patients were enrolled; 86 patients had calculus gallbladders, and 32 patients had acalculous gallbladders. After a mean follow- up of 33 months, 23 patients had recurrent biliary complications. Among 86 patients with calculus gallbladder, 15 patients had spontaneous clearance of gallbladder stones; 14 patients received cholecystectomy due to acute cholecystitis or recurrent colic pain with smooth postoperative courses. In the follow up period, six patients died of non-biliary causes. The GBEF is significant reduced in most patients with a calculus gallbladder in spite of stone color. Calculus gallbladder, alcohol drinking and more than one sessions of initial endoscopic treatment were found to be the risk factors of recurrent biliary complication. CONCLUSIONS: Gallbladder motility function was poorer in patients with a calculus gallbladder, but it cannot predict the recurrent biliary complication. Since spontaneous clearance of gallbladder stone may occur, wait and see policy of gallbladder management after endoscopic treatment of CBDS is appropriate, but regular follow- up in those patients with risk factors for recurrence is necessary.

RESUMO

BACKGROUND: Until recently, the role of antiviral prophylaxis in preventing hepatitis B virus (HBV) reactivation during immunosuppressive therapy or chemotherapy in patients with resolved HBV infection was unclear. The aim of the study reported here was to compare the efficacy of antiviral prophylaxis versus that of non-prophylaxis in resolved HBV-infected patients undergoing chemotherapy or immunosuppressive therapy. METHODS: PubMed, the Cochrane library, and the ClinicalTrials.gov website were searched from inception until December 2017. Studies comparing reactivation in prophylaxis versus non-prophylaxis in patients undergoing immunosuppressive therapy or chemotherapy were included. The meta-analysis was performed to calculate the relative risk (RR) and the pooled estimates. RESULTS: A meta-analysis was conducted of 13 studies (2 randomized controlled trials [RCTs] and 11 cohort studies). The summary RR for HBV reactivation was 0.47 (95% confidence interval [CI] 0.13-1.69) for antiviral prophylaxis versus non-prophylaxis. Both of the RCTs included in the meta-analysis enrolled patients treated with rituximab. Subgroup analyses showed that the two RCTs ± high-quality cohort studies showed a decreased risk of HBV reactivation among the antiviral prophylaxis groups (RCT 1: RR 0.13, 95% CI 0.02-0.70; P = 0.02; RCT 2: 0.28, 95% CI 0.08-0.98; P = 0.05). Subgroup analyses further showed that the cohort studies did not support an association between the antiviral prophylaxis groups and HBV reactivation (RR 0.62, 95% CI 0.14-2.83; P = 0.54); adjusting for confounding factors, such as detectable anti-HBs antibodies, failed to produce a significant association (RR,0.29, 95% CI 0.07-1.28; P = 0.10). CONCLUSION: Our meta-analyses did not show an association between antiviral prophylaxis use and risk of HBV reactivation. As using only the RCTs ± high-quality cohort studies data rendered this association significant, clinicians can consider providing antiviral prophylaxis to patients with resolved HBV infection who are undergoing rituximab-based therapy.

RESUMO

Hybrid therapy is a novel two-step treatment achieving a high eradication rate for Helicobacter pylori infection. Currently, whether this new therapy achieves a higher eradication rate than bismuth quadruple therapy remains an unanswered question. The aim of this prospective, randomized comparative study was to investigate the efficacies of 14-day hybrid therapy and bismuth quadruple therapy in the treatment of H. pylori infection. From July 2013 to June 2015, eligible H. pylori-infected subjects were randomly assigned to receive either 14-day bismuth quadruple therapy (pantoprazole, bismuth subcitrate, tetracycline, and metronidazole for 14 days) or 14-day hybrid therapy (a 7-day dual therapy with pantoprazole plus amoxicillin, followed by a 7-day quadruple therapy with pantoprazole plus amoxicillin, clarithromycin, and metronidazole). H. pylori status was examined 6 weeks after the end of treatment. Three hundred thirty H. pylori-infected participants were randomized to receive 14-day bismuth quadruple therapy (n = 164) or 14-day hybrid therapy (n = 166). The eradication rates by intention-to-treat analysis were similar: 93.9% versus 92.8%, respectively (95% confidence interval [CI], -4.3% to 5.4%; P = 0.68). Per-protocol analysis yielded similar results (96.7% versus 94.9%, respectively; P = 0.44). However, bismuth quadruple therapy had a higher frequency of adverse events than hybrid therapy (55.5% versus 15.7%, respectively; 95% CI, 30.4% to 49.2%; P < 0.001). The two treatments exhibited comparable drug adherence (93.9% versus 97%, respectively). The resistance rates of antibiotics were: clarithromycin, 16.7% of patients; amoxicillin, 1.3%; metronidazole, 25%; and tetracycline, 0%. In the bismuth quadruple therapy group, the eradication rate of metronidazole-resistant strains was lower than that of metronidazole-susceptible strains (70.0% versus 96.4%, respectively; P = 0.04). In the hybrid therapy group, no significant impact of clarithromycin or metronidazole resistance on eradication rates was identified. Both 14-day hybrid and bismuth quadruple therapies cure most patients with H. pylori infection in populations with moderate antibiotic resistance. However, the 14-day hybrid therapy has fewer adverse effects than the bismuth quadruple therapy. (This study has been registered at ClinicalTrials.gov under identifier NCT02541864.).

RESUMO

UNLABELLED: Reactivation of hepatitis B viral (HBV) infection in cancer patients undergoing chemotherapy may cause interruption of chemotherapy and lead to liver failure and death. In our institute, a computerized order entry-based alert system was introduced in September 2011 to remind healthcare providers of HBV testing when prescribing chemotherapy. Since August 2012, an order entry-based therapeutic control system has been applied to ensure HBV prophylaxis during chemotherapy. This retrospective cohort study included cancer patients receiving chemotherapy in the Kaohsiung Veterans General Hospital from November 2009 to June 2013. The prechemotherapy HBV screening rate, HBV prophylactic rate, and severe HBV acute exacerbation rate were compared between stages with different order systems. Newly diagnosed cancer patients (n = 2512) were included. The HBV testing rate in the screening reminder stage was higher than that in the educational stage (93.5% versus 40.2%, P < 0.001), whereas the adequate HBV prophylactic rates in the two order entry-based stages were comparable (41.1% versus 39.2%). Patients in the order entry-based therapeutic control stage had a higher HBV screening rate (99.3% versus 40.2%, P < 0.001) and a higher HBV prophylactic rate (95.8% versus 39.2%, P < 0.001) than those in the educational stage. Additionally, the severe HBV acute exacerbation rate in the therapeutic control stage was lower than those in the educational and screening reminder stages (0% versus 1.2% and 1.2%, respectively; both P < 0.01). CONCLUSION: A computerized order entry-based therapeutic control system can provide excellent prechemotherapy HBV screening for cancer patients undergoing chemotherapy and can effectively prevent severe acute exacerbation of HBV infection in hospitals among HBV endemic areas.

RESUMO

A previous study found that lamivudine, if started early enough, may improve the chance of survival in chronic hepatitis B virus (HBV) with severe acute exacerbation (SAE). The aim of this study was to investigate the effect of early entecavir treatment before the bilirubin level exceeds 20 mg/dl for chronic HBV with SAE. Consecutive patients with chronic HBV with SAE and a serum bilirubin level of <20 mg/dl who received lamivudine or entecavir were enrolled. Short-term (4 months) survival was evaluated. One hundred fourteen patients received lamivudine, and 53 patients received entecavir. The baseline characteristics were similar for the two groups except that the entecavir group was older and had a lower alanine aminotransferase (ALT) level. Three patients (8.0%) in the entecavir group and 9 patients (7.9%) in the lamivudine group died (P=1.000). If only patients who started antiviral treatment before serum bilirubin level rose to more than 15 mg/dl were included, 3 patients (8.3%) in the entecavir group and 3 patients (3.0%) in the lamivudine group died (P=0.189). If only patients with an HBV DNA level higher than 10(5) copies/ml and a bilirubin level lower than 15 mg/dl were included, 5 out of 40 patients (12.5%) in the entecavir group died and 1 out of 59 patients (1.7%) in the lamivudine group died. Multivariate analysis found that entecavir treatment was associated with more mortality than lamivudine (P=0.035). Early entecavir treatment in patients with high viral load is associated with more short-term mortality than lamivudine for chronic HBV with severe acute exacerbation.

RESUMO

With the rising prevalence of antimicrobial resistance, the failure rate of the standard triple therapy for Helicobacter pylori infection is increasing. Sequential therapy and concomitant therapy have been recommended to replace standard triple therapy for H. pylori eradication in regions with high clarithromycin resistance. The aim of this prospective, randomized, and controlled study was to simultaneously assess the efficacies of 10-day sequential and 7-day concomitant therapies versus a 7-day standard triple therapy for treating H. pylori infection. Consecutive H. pylori-infected subjects were randomly assigned to a 7-day standard triple therapy (pantoprazole, clarithromycin, and amoxicillin for 7 days), a 10-day sequential therapy (pantoprazole and amoxicillin for 5 days, followed by pantoprazole, clarithromycin, and metronidazole for a further 5 days), or a 7-day quadruple therapy (pantoprazole, clarithromycin, amoxicillin, and metronidazole for 7 days). H. pylori status was confirmed 6 weeks after therapy. Three hundred seven H. pylori-infected participants were randomized to receive triple (n = 103), sequential (n = 102), or concomitant (n = 102) therapies. The eradication rates by an intention-to-treat analysis in the three treatment groups were 81.6% (95% confidence interval [CI], 74.1% to 89.0%), 89.2% (95% CI, 83.2% to 95.2%), and 94.1% (95% CI, 89.5% to 98.7%). The seven-day concomitant therapy had a higher eradication rate than did the 7-day triple therapy (difference, 12.5%; 95% CI, 3.7% to 21.3%). There were no significant differences in the eradication rates between the sequential and standard triple therapies. All three treatments exhibited similar frequencies of adverse events (8.7%, 8.8%, and 13.7%, respectively) and drug compliance (99.0%, 98.0%, and 100.0%, respectively). In conclusion, the seven-day concomitant therapy is superior to the 7-day standard triple therapy for H. pylori eradication. Additionally, it is less complex than the 10-day sequential therapy because the drugs are not changed halfway through the treatment course. (This study has been registered at ClinicalTrials.gov under registration no. NCT1769365.).

RESUMO

BACKGROUND: Sequential therapy has been recommended in the Maastricht IV/Florence Consensus Report as the first-line treatment for Helicobacter pylori eradication in regions with high clarithromycin resistance. However, it fails in 5-24% of infected subjects, and the recommended levofloxacin-containing triple rescue therapy only achieves a 77% eradication rate after failure of sequential therapy. AIM: To investigate the efficacy of a novel quadruple therapy comprising proton-pump inhibitor, bismuth, tetracycline, and levofloxacin for rescue treatment of sequential therapy. METHODS: This was a multicenter study in which H. pylori-infected patients who had failed sequential therapy received a 10-day quadruple therapy (esomeprazole (40 mg b.d), tripotassium dicitrato bismuthate (120 mg q.d.s.), tetracycline (500 mg q.d.s.), and levofloxacin (500 mg o.d.) for 10 days). H. pylori status was examined 6 weeks after the end of treatment. RESULTS: From July 2007 to June 2012, twenty-four subjects received 10-day quadruple therapy. The eradication rates according to intention-to-treat and per-protocol analyses were both 95.8% (23 of 24; 95% confidence interval, 87.8-103.8%). Adverse events were seen in 25.0% (6 of 24) of the patients. Drug compliance was 100.0% (24/24). CONCLUSIONS: The 10-day quadruple therapy comprising proton-pump inhibitor, bismuth, tetracycline, and levofloxacin achieves a very high eradication rate for H. pylori infection after failure of sequential therapy. It is well tolerated and has great potential to become a good choice of rescue treatment following non-bismuth-containing quadruple therapy in regions with high clarithromycin resistance.

RESUMO

We evaluated second-line salvage therapy with adefovir + telbivudine (group 1), adefovir followed by adefovir + telbivudine (group 2), or lamivudine + adefovir followed by adefovir + telbivudine (group 3) in hepatitis B patients with an inadequate virologic response to lamivudine treatment. Simple linear regression analysis showed that for each additional month of treatment, the most significant reduction in viral load occurred in group 1 (HBV DNA [Log10 IU/mL]: group 1, -0.149; group 2, -0.081; group 3, -0.123). Generalized estimating equation analysis revealed that compared to group 1, hepatitis B virus (HBV) DNA levels were 1.203 and 0.443 Log10 IU/mL higher in groups 2 and 3, respectively. Overall, a significant reduction in viral load (-0.060 Log10 IU/mL) was observed for each additional month of treatment. Adefovir + telbivudine treatment resulted in a significant reduction in HBV DNA levels. Moreover, telbivudine treatment resulted in a significant reduction in viral load (-0.050 Log10 IU/mL) compared to lamivudine treatment after the emergence of lamivudine resistance.

RESUMO

BACKGROUND: Endoscopic variceal ligation (EVL) is effective in preventing esophageal variceal rebleeding. However, the optimal EVL interval remains unclear. AIM: To investigate the effectiveness and safety of EVL using two intersession intervals. methods: From January 2009 to October 2012, 214 patients with acute esophageal variceal bleeding were screened. Emergency ligation was performed for patients with acute variceal bleeding. After achieving hemodynamic stability, eligible patients (n = 70) were randomized to either the monthly group or the biweekly group. RESULTS: Median time from randomization to variceal obliteration was 2.7 months in the monthly group and 1.7 months in the biweekly group, at a mean of 2.3 ± 2.0 and 3.0 ± 1.8 sessions, respectively. After a median follow up of 23 months, six patients (17%) in the monthly group and nine patients (26%) in the biweekly group developed upper gastrointestinal rebleeding (P = 0.382). Esophageal variceal rebleeding occurred in six patients (17%) in the monthly group and in seven patients (20%) in the biweekly group (P = 0.759). No rebleeding from EVL ulcers occurred in the monthly group and was 5.7% (n = 2) for the biweekly group. Both treatment groups had similar rates of esophageal variceal recurrence and mortality. Notably, the incidence of post-EVL ulcers in the monthly group was lower than that in the biweekly group (11% vs 57%, P < 0.001). CONCLUSIONS: Patients receiving EVL monthly had similar rebleeding rate, variceal recurrence, and mortality to those receiving EVL biweekly for secondary prophylaxis of variceal bleeding; however, the monthly interval was associated with fewer post-EVL ulcers found at follow-up endoscopies.

RESUMO

BACKGROUND AND AIM: There is limited data on the efficacy and outcome of telbivudine (LdT) therapy in patients with chronic hepatitis B and compensated cirrhosis. We evaluated LdT as first-line therapy in these patients and compared with those treated with entecavir (ETV). METHODS: We consecutively enrolled 88 chronic hepatitis B patients with compensated cirrhosis primarily treated with LdT at least for 2 years or less than 2 years but developed resistance, and evaluated the efficacy and clinical outcomes. Meanwhile, we matched a control group who treated with ETV for comparison. RESULTS: In LdT group, alanine aminotransferase normalization (65.8%), hepatitis B e antigen seroconversion (39.8%), hepatitis B virus (HBV) DNA undetectablility (71.6%), and virologic resistance (23.9%) were noted after 2 years treatment. Compared with ETV group, there were significant difference in HBV DNA undetectablility (P < 0.001) and virologic resistance (P < 0.001). In addition, the decline of serum hepatitis B surface antigen levels, hepatocellular carcinoma development, mortality, disease progression, and the change of renal function were similar. Cox regression analysis showed that pretreatment low albumin level and high model for end-stage liver disease scores were risk factors for disease progression. CONCLUSIONS: These results indicated that although LdT and ETV are similar in clinical outcomes for patients with HBV-related compensated cirrhosis, LdT still had lower HBV undetectablility and higher resistant rate after 2 years treatment, which was a challenge for being as first-line therapy in these patients who need lifelong therapy.

RESUMO

BACKGROUND: Lean individuals with non-alcohol fatty liver disease (NAFLD) often have normal body size but abnormal visceral fat. Therefore, an alternative to body mass index should be considered for prediction of lean-NAFLD. This study aimed to use representative visceral fat links with other laboratory parameters using the least absolute shrinkage and selection operator (LASSO) method to construct a predictive model for lean-NAFLD. METHODS: This retrospective cross-sectional analysis enrolled 2325 subjects with BMI < 24 kg/m2 from medical records of 51,271 examinees who underwent a routine health check-up. They were randomly divided into training and validation cohorts at a ratio of 1:1. The LASSO-derived prediction model used LASSO regression to select 23 clinical and laboratory factors. The discrimination and calibration abilities were evaluated using the Hosmer-Lemeshow test and calibration curves. The performance of the LASSO model was compared with the fatty liver index (FLI) model. RESULTS: The LASSO-derived model included four variables-visceral fat, triglyceride levels, HDL-C-C levels, and waist hip ratio-and demonstrated superior performance in predicting lean-NAFLD with high discriminatory ability (AUC, 0.8416; 95% CI: 0.811-0.872) that was comparable with the FLI model. Using a cut-off of 0.1484, moderate sensitivity (75.69%) and specificity (79.86%), as well as high negative predictive value (95.9%), were achieved in the LASSO model. In addition, with normal WC subgroup analysis, the LASSO model exhibits a trend of higher accuracy compared to FLI (cut-off 15.45). CONCLUSIONS: We developed a LASSO-derived predictive model with the potential for use as an alternative tool for predicting lean-NAFLD in clinical settings.


Researchers developed a model to predict a type of liver disease called non-alcoholic fatty liver disease (NAFLD) in lean individuals.The model accurately detects NAFLD in lean individuals using factors like visceral fat, triglyceride levels, and waist-to-hip ratio, aiding in identifying the disease in normal-weight people with abnormal fat distribution.

RESUMO

BACKGROUND: Hepatocellular carcinoma (HCC) with major portal vein invasion (MPVI) presents very poor outcomes. Hepatic artery infusion chemotherapy (HAIC) and radiation therapy (RT) have both been found to be effective for advanced HCC. In this retrospective study, we compared the therapeutic outcomes of our "new" HAIC regimen with and without concurrent RT, before and after propensity score matching (PSM) in treating HCC patients with MPVI. METHODS: One hundred forty patients with MPVI received HAIC alone and 35 patients underwent concurrent HAIC and RT during a 16-year period. The left subclavian artery was adopted as the entry site for a temporary catheter placement for a 5-day chemoinfusion. The Modified Response Evaluation Criteria in Solid Tumors (mRECIST) was adopted to assess the objective response rate (ORR). The Kaplan-Meier curve was used to calculate progression-free survival (PFS) and overall survival (OS) between the two groups. Univariate and multivariate analyses by Cox regression model were used to assess hazard ratios. RESULTS: Of the 140 patients with Child-Pugh A liver function, the median OS was 17.0 months. In the initial cohort, higher ORR and PFS were found in the concurrent RT group than in the HAIC alone group (80% vs 66.4% and 9 vs 8 months, respectively) but shorter OS (10.5 vs 14.5 months, p = 0.039) was observed. After PSM, the OS was 10 and 15 months ( p = 0.012), respectively. Multivariable Cox regression analysis revealed that the significant factors for adjusting hazard ratios for OS were Child-Pugh classification, alpha fetal protein (AFP) level, and hepatic vein invasion. CONCLUSION: HAIC is an effective treatment for advanced HCC patients with MPVI. Concurrent HAIC and full-dose RT were associated with worse clinical outcomes.
