Risk of Hepatocellular Carcinoma Remains High in Patients with HBV-Related Decompensated Cirrhosis and Long-Term Antiviral Therapy

Background. This study aimed to evaluate the risk factors of HCC development in patients with hepatitis B virus (HBV)-related DC and who underwent long-term antiviral therapy. Methods. Data from 308 patients with HBV-related DC and long-term antiviral therapy were collected and retrospectively reviewed. Cox regression analysis was used to analyze independent risk factors of HCC development. Results. Data from 129 patients with definite records were analyzed. The median follow-up time was 5 years (range, 1 to 8 years). At the end of the follow-up, 41 (31.8%) patients developed HCC, and the time from DC diagnosis to HCC incidence who received antiviral therapy was 4.4 years (range, 1–7 years). The incidence of HCC was higher in males (30/78, 38.5%) than in females (11/51, 21.6%) ( P = 0.04). Patients who developed HCC were significantly older than those who did not develop HCC ( P < 0.01). The incidence of HCC in patients receiving nucleoside analogues, nucleotide analogues, and combination therapy was 34.7%, 38.1%, and 33.3%, respectively, and the difference showed no significant differences ( P = 0.95). Multivariate Cox regression analysis demonstrated that male gender and age ≥50 years are independent risk factors of HCC development (OR = 2.987 and 2.408; 95% CI (1.301–6.858) and (1.126–5.149); P = 0.01 and 0.02, respectively). Conclusion. The risk of HCC remains to be high in patients with HBV-related DC, especially in males aged ≥50 years.

Objectives The ankle–brachial index is a noninvasive modality to evaluate atherosclerosis and is a predictive role for future cardiovascular events and mortality. However, few studies have evaluated its relation to long-term future ischemic stroke in hemodialysis patients. Therefore, we examined the relationship between ankle–brachial index and ischemic stroke events among hemodialysis patients in a seven-year follow-up. Methods A total of 84 patients were enrolled. Ankle–brachial index was assessed in January 2009. Primary outcomes included ischemic stroke. An ankle–brachial index < 0.9 was considered abnormal and 1.4 ≥ ankle–brachial index ≥ 0.9 to be normal ankle–brachial index. Results Mean values for ankle–brachial index were 0.98 ± 0.21at study entrance. In addition, 28 patients encountered ischemic stroke in the seven-year follow-up. In univariate Cox regression analysis, old age (hazard ratio (HR): 1.065, 95% confidence interval (CI): 1.030–1.102, p < 0.001), low seven-year averaged serum phosphate levels (HR: 0.473, 95% CI: 0.306–0.730, p = 0.001), and abnormal ankle–brachial index (HR: 0.035, 95% CI: 0.009–0.145, p < 0.001) were risk factors for ischemic stroke. In multivariate Cox regression analysis for significant variables in univariate analysis, abnormal ankle–brachial index (HR: 0.058, 95% CI: 0.012–0.279, p < 0.001) and low seven-year averaged serum phosphate levels (HR: 0.625, 95% CI: 0.404–0.968, p = 0.035) remained the risk factors for ischemic stroke. The risk of ischemic stroke was 3.783-fold in patients with abnormal ankle–brachial index compared with patients with normal ankle–brachial index (HR: 3.783, 95% CI: 1.731–8.269, p = 0.001). Conclusions These findings suggest that ankle–brachial index is an impressive predictor of future ischemic stroke among hemodialysis patients.

Abstract Objective: The purpose of this study was to identify the relationship between coagulopathy during the perioperative period (before the operation and on the first day after the operation) and the long-term survival of TBI patients undergoing surgery, as well as to explore the predisposing risk factors that may cause perioperative coagulopathy.Methods: This retrospective study included 447 TBI patients who underwent surgery from January 1, 2015 to April 25, 2019. Clinical parameters, including patient demographic characteristics, biochemical tests, perioperative coagulation function tests (before the operation and on the first day after the operation) and intraoperative factors were collected. Log-rank univariate analysis and Cox regression models were conducted to assess the relationship between perioperative coagulopathy and the long-term survival of TBI patients. Furthermore, univariate and multivariate analyses were performed to identify the underlying risk factors for perioperative coagulopathy.Results: Multivariate Cox regression analysis identified age, AIS(head) = 5, GCS ≤ 8, systolic pressure at admission < 90 mmHg and postoperative coagulopathy (all P < 0.05) as independent risk factors for survival following TBI; we were the first to identify postoperative coagulopathy as an independent risk factor. According to multivariate logistic regression analysis, for the first time, abnormal ALT and RBC at admission, preoperative coagulopathy, infusion of colloidal solution > 1100 mL and intraoperative bleeding > 950 mL (all P < 0.005) were identified as independent risk factors for postoperative coagulation following surgery after TBI.Conclusions: Those who suffered from postoperative coagulopathy due to TBI had a higher hazard for poor prognosis than those who did not. Closer attention should be paid to postoperative coagulopathy and more emphasis should be placed on managing the underlying risk factors.

Clinical Variables

The use of hydraulic silicate cements (HSCs) for vital pulp therapy has been found to release calcium and hydroxyl ions promoting pulp tissue healing and mineralized tissue formation. The present study investigated whether HSCs such as mineral trioxide aggregate (MTA) affect their biological and antimicrobial properties when used as long-term pulp protection materials. The effect of variables on treatment outcomes of three HSCs (ProRoot MTA, OrthoMTA, and RetroMTA) was evaluated clinically and radiographically over a 48–78 month follow-up period. Survival analysis was performed using Kaplan–Meier survival curves. Fisher’s exact test and Cox regression analysis were used to determine hazard ratios of clinical variables. The overall success rate of MTA partial pulpotomy was 89.3%; Cumulative success rates of the three HSCs were not statistically different when analyzed by Cox proportional hazard regression analysis. None of the investigated clinical variables affected success rates significantly. These HSCs showed favorable biocompatibility and antimicrobial properties in partial pulpotomy of permanent teeth in long-term follow-up, with no statistical differences between clinical factors.

Background: The aim of our study was to develop a nomogram model to predict overall survival (OS) and cancer-specific survival (CSS) in patients with gastric signet ring cell carcinoma (GSRC). Methods: GSRC patients from 2004 to 2015 were collected from the Surveillance, Epidemiology, and End Results (SEER) database and randomly assigned to the training and validation sets. Multivariate Cox regression analyses screened for OS and CSS independent risk factors and nomograms were constructed. Results: A total of 7,149 eligible GSRC patients were identified, including 4,766 in the training set and 2,383 in the validation set. Multivariate Cox regression analysis showed that gender, marital status, race, AJCC stage, TNM stage, surgery and chemotherapy were independent risk factors for both OS and CSS. Based on the results of the multivariate Cox regression analysis, prognostic nomograms were constructed for OS and CSS. In the training set, the C-index was 0.754 (95% CI = 0.746-0.762) for the OS nomogram and 0.762 (95% CI: 0.753-0.771) for the CSS nomogram. In the internal validation, the C-index for the OS nomogram was 0.758 (95% CI: 0.746-0.770), while the C-index for the CSS nomogram was 0.762 (95% CI: 0.749-0.775). Compared with TNM stage and SEER stage, the nomogram had better predictive ability. In addition, the calibration curves also showed good consistency between the predicted and actual 3-year and 5-year OS and CSS. Conclusion: The nomogram can effectively predict OS and CSS in patients with GSRC, which may help clinicians to personalize prognostic assessments and clinical decisions.

Observation Period

The majority of patients with myelodysplastic syndromes (MDS) require regular red blood cell (RBC) transfusions. Alloimmunization (AI) against blood products is an adverse event, causing time-consuming RBC compatibility testing. The reported incidence of AI in MDS patients varies greatly. Even though different studies on AI in MDS patients have been performed, there are still knowledge gaps. Current literature has not yet fully identified the risk factors and dynamics of AI in individual patients, nor has the influence of disease modifying treatment (DMT) been explored. Therefore, we performed this study to evaluate the effect of DMT on AI. An observational, population-based study, using the HemoBase registry, was performed including all newly diagnosed MDS patients between 2005 and 2017 in Friesland, a province of the Netherlands. All available information about treatment and transfusions, including transfusion dates, types, and treatment regimens, was collected from the electronic health records and laboratory systems. Follow-up occurred through March 2019. For our patient cohort, blood products were matched for AB0 and RhD, and transfused per the 'type and screen' policy (i.e. electronic matching of blood group phenotype between patient and donor). After a positive antibody screening, antibody identification and Rh/K phenotyping was performed and subsequent blood products were (cross)matched accordingly. The observation period was counted from first transfusion until last transfusion or first AI event. Univariate analyses and cumulative frequency distributions were performed to study possible risk factors and dynamics of AI. DMT was defined as hypomethylating agents, lenalidomide, chemotherapy and monoclonal antibodies. The effect of DMT as a temporary risk period on the risk of AI was estimated with incidence rates, relative risks (RR) and hazard ratios (HR) using a cox regression analysis. Follow-up was limited to 24 months for the cox regression analysis to avoid possible bias by survival differences. Statistical analyses were performed using IBM SPSS 24 and SAS 9.4. Out of 292 MDS patients, 236 patients received transfusions and were included in this study, covering 463 years of follow-up. AI occurred in 24 patients (10%). AI occurred mostly in the beginning of the observation period: Eighteen patients (75%) were alloimmunized after receiving 20 units of RBCs, whereas 22 patients (92%) showed AI after 45 units of RBCs (Figure 1). We found no significant risk factors for AI in MDS patients at baseline. DMT was given to 67 patients (28%) during the observation period. Patients on DMT received more RBC transfusions than patients that did not receive DMT (median of 33 (range: 3-154) and 11 (range: 0-322) RBC units respectively, p<0,001). Four AI events (6%) occurred in patients on DMT and 20 AI events (12%) occurred in patients not on DMT. Cox regression analysis of the first 24 months of follow-up showed an HR of 0.30 (95% CI: 0.07-1.31; p=0.11). The incidence rates per 100 person-years were 3.19 and 5.92 respectively. The corresponding RR was 0.54 (95% CI: 0.16-1.48; p=0.26). Based on our results, we conclude that the incidence of AI in an unselected, real world MDS population receiving RBC transfusions is 10% and predominantly occurred in the beginning of follow-up. Risk factors for AI at baseline could not be identified. Our data showed that patients on DMT received significantly more RBC transfusions but were less susceptible to AI. Therefore, extensive matching of blood products may not be necessary for patients on DMT. Larger studies are needed to confirm the protective effect of DMT on AI.

Abstract Background CHA2DS2-VASc score has been used as a surrogate marker for predicting outcomes beyond thromboembolic risk in patients with atrial fibrillation (AF). Likewise, cardiac troponin I (cTnI) is a predictor of mortality in AF. Purpose This study aimed to investigate the association of cTnI and CHA2DS2-VASc score with long-term prognosis in patients admitted to the emergency department with AF. Methods A retrospective cohort study conducted between January 2012 and December 2013, enrolling patients admitted to the emergency department with AF and having documented cTnI measurements. CHA2DS2-VASc score was estimated. Primary endpoint was 5-year all-cause mortality, readmission for heart failure (HF), readmission for myocardial infarction (MI) and the composite end point of major adverse cardiac events defined as death, readmission for HF or readmission for MI (MACE). Results A total of 578 patients with AF were studied, of whom 252 patients had elevated levels of cTnI (43.6%) and 334 patients had CHA2DS2-VASc score >3 (57.8%). Patients with elevated cTnI tended to be oldercompared with those who did not have cTnI elevation and were more frequently comorbid and of higher ischemic risk, including hypertension, prior MI, prior HF, chronic renal failure and peripheral artery disease. The overall median CHA2DS2-VASc score was higher in those with cTnI elevation compared to those patients elevated cTnI levels (4.2 vs 3.3 points, p<0.001). Main diagnoses at hospital discharge were tachyarrhythmia 30.3%, followed by heart failure 17.7%, respiratory infections 9.5% and acute coronary syndrome 7.3%. At 5-year follow-up, all-cause death was significantly higher for patients with cTnI elevation compared with those who did not have cTnI elevation (56.4% vs. 27%; logrank test p<0.001). Specifically, for readmissions for HF and readmissions for MI there were no differences in between patients with or without cTnI elevation. In addition, MACE was reached in 165 patients (65.5%) with cTnI elevation, compare to 126 patients (38.7%) without cTnI elevation (p<0.001). On multivariable Cox regression analysis, cTnI elevation was an independent predictor of all-cause death (hazard ratio, 1.67, 95% confidence interval [CI]: 1.24–2.26, p=0.001) and of MACE (hazard ratio 1.47, 95% confidence interval 1.15–1.88; P=0.002), but it did not reach statistical significance for readmissions for MI and readmissions for HF. CHA2DS2-VASc score was a predictor on univariate Cox regression analysis for each endpoint, but it did not reach significance on multivariable Cox regression analysis for any endpoint. Conclusions cTnI is independently associated with long-term all-cause mortality in patients attending the emergency department with AF. cTnI compared to CHA2DS2-VASc score is thus a biomarker with predictive capacity for mortality in late follow-up, conferring utility in the risk stratification of patients with atrial fibrillation.

Abstract Background: Metabolic syndrome (MS) could promote the development of cardiovascular disease(CVD). The aim of this study was to examine the association of MS and its components with CVD among Kazakhs in Xinjiang. Methods: According to the geographical distribution of the minority populations in Xinjiang, we selected the representative prefecture (Yili). A total of 2,644 participants completed the baseline survey between April 2010 and December 2012. The follow-up survey was conducted from April 2016 to December 2016. Only 2,286 out of 2,644 participants were followed-up on, with a follow-up rate of 86.46%. Cox regression was used to evaluate the association of each component and the number of combinations of MS components on the development of CVD. Results: Multivariate Cox regression analysis showed that blood pressure (BP), waist circumference (WC), and triglycerides (TG) were independently associated with CVD. Participants with 1–5 MS components had an increased hazard ratio for developing CVD, from 1.82 to 8.59 (trend P<0.001), compared with those without any MS components. This trend persisted after adjusting for other general risk factors. The risk of developing CVD increased when TG and WC coexisted, or when TG/WC and BP coexisted. However, no significant interactions were found between BP , WC , and TG. Conclusions: BP , WC, and TG were independent risk factors for CVD in Kazakhs. In clinical practice, a more informative assessment may be obtained by taking into account the number of MS components.

Abstract Backgrounds: The prognosis of thoracic aortic pseudoaneurysm (TAP) after thoracic endovascular aortic repair (TEVAR) remains unclear. This study investigates the early and midterm clinical outcome as well as relevant risk factors of TAP patients following TEVAR therapy.Methods: From July 2010 to July 2020, 37 eligible TAP patients who underwent TEVAR were selected into our research. We retrospectively explored their baseline, perioperative and follow-up data. Fisher exact test and Kaplan-Meier method were applied for comparing difference between groups. Risk factors of late survival were discerned using Cox regression analysis.Results: There were 29 men and 12 women, with the mean age as 59.5±13.0 years (range, 30-82). The mean follow-up time was 30.7±28.3 months (range, 1-89). For early result, early mortality (≦30days) happened in 3(8.1%) zone 3 TAP patients versus 0 in zone 4 (p= 0.028); acute arterial embolism of lower extremity and type II endoleak respectively occurred in 1(2.7%) case. For midterm result, survival at 3 months, 1 year and 5 years was 88.8±5.3%, 75.9±7.5% and 68.3±9.9%, which showed significant difference between zone 2/3 versus zone 4 group (56.3±14.8% versus 72.9±13.2%, p= 0.013) and emergent versus elective TEVAR groups (0.0±0.0% versus 80.1±8.0%, p= 0.049). On multivariate Cox regression, lesions at zone 2/3 (HR 4.605, 95%CI 1.095-19.359), concomitant cardiac disease (HR 4.932, 95%CI 1.086-22.403) and emergent TEVAR (HR 4.196, 95%CI 1.042-16.891) were significant independent risk factors for worse late clinical outcome. Conclusions: TEVAR therapy is effective and safe with satisfactory early and midterm clinical outcome for TAP patients. Lesions at zone 2/3, concomitant cardiac disease and emergent TEVAR were independent risk factors for midterm survival outcome.

Uncemented Total Hip Arthroplasty

Abstract Background Despite the increased use of uncemented total hip arthroplasty (UTHA), there is little evidence of its superiority over cemented total hip arthroplasty (CTHA). The purpose of this retrospective study was to compare the long-term survivorship and Harris Hip Scores (HHSs) of CTHA versus UTHA in the treatment of acute femoral neck fractures (FNFs). Methods Data involving 224 hips (CTHA, n= 112; UTHA, n=112) that underwent primary surgery in our medical institutions during 2005-2017 were analysed retrospectively. The primary endpoint was the risk of all-cause revision. The difference in the risk of all-cause revision between groups was assessed by Kaplan-Meier survival analysis with a log-rank test and Cox regression analysis. Results The mean follow-up from surgery was 10 years (range, 3 - 13 years). Kaplan-Meier estimated that the 10-year implant survival was 98.1% (CI: 96.1–98.5) in the CTHA group and 96.2% (CI: 95.2–97.3) in the UTHA group (p = 0.030). The adjusted Cox regression analysis demonstrated a lower risk of revision in CTHA than in UTHA (hazard ratio [HR] = 1.4, 95% confidence interval [CI] = 1.1-2.6, p = 0.000). At the final follow-up, significant differences were detected in HHS (85.10[±12.21] for CTHA vs. 79.11[±13.19] for UTHA). Conclusion This retrospective analysis demonstrates that CTHA has superior survival to UTHA, with a significantly reduced revision risk and higher functional outcome scores. Further follow-up is necessary to verify whether the CTHA advantage persists over time.

Abstract BACKGROUND: Trauma is a damage caused by physical harm from external source. It has been one of the major causes of mortality. The purpose of this study was to explore the risk factors related to mortality among emergency trauma patients. METHODS: This was a retrospective study in trauma center of the First Affiliated Hospital of Soochow University. The data were obtained from trauma database with patients registered from November 1, 2016 to November 30, 2019.Shapiro–Wilk test, Mann-Whitney test and Likelihood-ratio Chi squared test were used to assess the survival pattern. Cox regressions were performed to calculate the hazard ratios (HRs) of variables for death. RESULTS: The total 1739 emergency trauma patients, 44 (2.53%) died during the study period and 1695 (97.47%) were survival. Through univariable and multivariable Cox regression analysis, three independent risk factors for emergency death were screened out: pulse (Crude HR: 0.97, 95% Confidence Interval [CI]: 0.96-0.98; Adjuste HR: 1.04, 95% CI: 1.02-1.06), pulse oxygen saturation (Crude HR: 0.96, 95% CI: 0.95-0.97; Adjuste HR: 0.94, 95% CI: 0.91-0.97) and Revised Trauma Score (Crude HR: 0.69, 95% CI: 0.65-0.74; Adjuste HR: 0.79, 95% CI: 0.64-0.97).CONCLUSION: The survival outcome of emergency trauma patients was influenced by many factors. Pulse, pulse oxygen saturation (SpO2 ) and Revised Trauma Score (RTS) were the independent risk factors for mortality. Accurate analysis and judgment of the risk factors can improve cure efficiency and long-term survival rate.
