Risk Factors for Venous Thromboembolism in Endometrial Cancer

Background: Venous thromboembolism (VTE) in malignancy is associated with poor outcomes. We conducted a retrospective review of VTE in patients with endometrial cancer to characterize the VTE incidence, identify factors that contribute to VTE risk, and compare survival outcomes in patients with and without VTE. Methods: A retrospective chart review identified 422 eligible patients who underwent surgery for endometrial cancer (1 January 2014 to 31 July 2016). The primary outcome was VTE. Binary logistic regression identified risk factors for VTE; significant risk factors were included in a multivariate analysis. Kaplan–Meier estimates are reported, and log rank tests were used to compare the Kaplan–Meier curves. Risk-adjusted estimates for overall survival based on VTE were determined using a multivariate Cox proportional hazards model. Results: The incidence of VTE was 6.16% overall and 0.7% within 60 days postoperatively. Non-endometrioid histology, stages 3 and 4 disease, laparotomy, and age (p < 0.1) were identified as factors associated with VTE and were included in a multivariate analysis. The overall death rate in patients with VTE was 42% (9% without VTE): hazard ratio, 5.63; 95% confidence interval, 2.86 to 11.08; p < 0.0001. Adjusting for age, stage of disease, and histology, risk of death remained significant for patients with a VTE: hazard ratio, 2.20; 95% confidence interval, 1.09 to 4.42; p = 0.0271. Conclusions: A method to identify patients with endometrial cancer who are at high risk for VTE is important, given the implications of VTE for patient outcomes and the frequency of endometrial cancer diagnoses. Factors identified in our study might assist in the recognition of such patients.

Risk Of Death

IntroductionPatients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection may develop coronavirus disease 2019 (COVID-19). Risk factors associated with death vary among countries with different ethnic backgrounds. We aimed to describe the factors associated with death in Mexicans with confirmed COVID-19.Material and methodsWe analysed the Mexican Ministry of Health’s official database on people tested for SARS-CoV-2 infection by real-time reverse transcriptase–polymerase chain reaction (rtRT-PCR) of nasopharyngeal fluids. Bivariate analyses were performed to select characteristics potentially associated with death, to integrate a Cox-proportional hazards model.ResultsAs of May 18, 2020, a total of 177,133 persons (90,586 men and 86,551 women) in Mexico received rtRT-PCR testing for SARS-CoV-2. There were 5332 deaths among the 51,633 rtRT-PCR-confirmed cases (10.33%, 95% CI: 10.07–10.59%). The median time (interquartile range, IQR) from symptoms onset to death was nine days (5–13 days), and from hospital admission to death 4 days (2–8 days). The analysis by age groups revealed that the significant risk of death started gradually at the age of 40 years. Independent death risk factors were obesity, hypertension, male sex, indigenous ethnicity, diabetes, chronic kidney disease, immunosuppression, chronic obstructive pulmonary disease, age > 40 years, and the need for invasive mechanical ventilation (IMV). Only 1959 (3.8%) cases received IVM, of whom 1893 were admitted to the intensive care unit (96.6% of those who received IMV).ConclusionsIn Mexico, highly prevalent chronic diseases are risk factors for death among persons with COVID-19. Indigenous ethnicity is a poorly studied factor that needs more investigation.

Overall Mortality

SummaryFew studies have addressed the topic of venous thromboembolism (VTE) in patients hospitalised in rehabilitation facilities. This patient population is rapidly growing, and data aimed to better define VTE risk in this setting are needed. Primary aim of this prospective observational study was to evaluate the frequency of symptomatic, objectively confirmed VTE in a cohort of unselected consecutive patients admitted to rehabilitation facilities, after medical diseases or surgery. Further objectives were to assess overall mortality, to identify risk factors for VTE and mortality, and to assess the attitude of physicians towards thromboprophylaxis. A total of 3,039 patients were included in the study, and the median duration of hospitalisation was 26 days. Seventy-two patients (2.4%) had symptomatic VTE. The median time to VTE from admission to the long-term care unit was 13 days. According to multivariable analysis, previous VTE (hazard ratio 5.67, 95% confidence interval 3.30–9.77) and cancer (hazard ratio 2.26, 95% confidence interval 1.36–3.75) were significantly associated to the occurrence of VTE. Overall in-hospital mortality was 15.1%. Age over 75 years, male gender, disability, cancer, and the absence of thromboprophylaxis were significantly associated to an increased risk of death (multivariable analysis). In-hospital antithrombotic prophylaxis was administered to 75.1% of patients, and low-molecular-weight heparin was the most widely used agent. According to our study, patients admitted to rehabilitation facilities remain at substantially increased risk for VTE. Because this applies to the majority of these patients, there is a great need for clinical trials assessing optimal prophylactic strategies.

Abstract Background: Venous thromboembolism (VTE) is an uncommon but clinically significant postoperative complication in children. Incidence of VTE in pediatric patients ranges from 34-58 per 10,000 hospitalized children1. Due to rarity of these events, there is limited information about the factors predisposing children to VTE after surgery. We queried a national surgical database to identify risks and outcomes associated with VTE in pediatric surgical patients. Methods: The National Surgical Quality Improvement Program-Pediatric (NSQIP) is a prospectively collected database that records pediatric surgical information, surgical approaches, and 30 day patient outcomes. The database was queried for the years 2012-2013 to identify pediatric patients (age < 18) who had received surgical intervention and were diagnosed with postoperative VTE. Because of their separate coding in NSQIP, we defined VTE as including venous thromboembolism, or pulmonary embolism (PE) diagnosed radiographically within 30 days of operation. To reduce non-random differences between patients we used propensity scores based on age, sex, race, BMI, and ASA classification to match patients in a 1:2 ratio using the nearest neighbor method. Using univariate and multivariate analysis, we identified preoperative risk factors associated with VTE. Results: In total, 130 patients were identified who developed VTE postoperatively (VTE n=122, PE n=7, BOTH PE + VTE n= 1) from this database of 114,395 patients. There were 104 patients with VTE that also had complete entries and were subsequently analyzed in this study. Surgical specialties treating patients in this analysis included cardiothoracic surgery, general surgery, neurosurgery, orthopedic surgery, otolaryngology, plastic surgery, and urology. Eighty-one unique operative CPT codes were identified for patients with VTE. Patients who developed VTE had increased operative time, anesthesia time, and total length of stay (all p < 0.001). Multivariate analysis demonstrated that pneumonia (odds ratio [OR] 1.73, 95% confidence interval [CI] 1.3 - 2.29), Central Line Associated Bloodstream Infection (CLABSI) (OR 1.69, 95% CI 1.18 - 2.42), sepsis (OR 1.47, 95% CI 1.18 - 1.82), septic shock (OR 1.36, 95% CI 1.06 - 1.75), and current solid or hematologic malignancy or active treatment of malignancy (OR 1.30, 95% CI 1.08 - 1.58) were all statistically significant risk factors associated with development of VTE (all p < 0.05). Conclusions: Postoperative VTE risk is significantly increased in children with malignancy or severe infections. Further research is needed to understand the mechanism between malignancy, systemic inflammation, and VTE risk in children. These findings may help to identify patients in need of prophylactic treatment in order to reduce postoperative thrombotic risk in pediatric patients. References: 1.

Statin Use

ObjectivePreclinical data and recent epidemiological studies suggest that statins have antiproliferative and antimetastatic effects in various cancer cells, and reduce cancer mortality and recurrence. We study the effect of statin use on survival outcomes and recurrence rates in patients with endometrial cancer with high-risk histology.Materials and MethodsAll patients receiving definitive therapy for high-risk endometrial cancer from 1995 to 2014 were retrospectively reviewed. Health characteristics at baseline were collected, and statin use was determined from medical records. Overall survival (OS) and progression-free survival (PFS) were estimated using the Kaplan-Meier method and compared using the log-rank test. Cox proportional hazards regression models were used for univariate and multivariate analysis to determine independent factors associated with OS and PFS.ResultsA total of 199 patients were included in the study, of which 76 were hyperlipidemic and 50 used statins. The median follow-up time was 31 months from time of diagnosis. Hyperlipidemic patients who used statins had improved OS compared with hyperlipidemic patients not using statins (hazard ratio, 0.42; 95% confidence interval, 0.20–0.87;P= 0.02). Statin use was also associated with improved PFS (hazard ratio, 0.47; 95% confidence interval, 0.23–0.95;P= 0.04) on multivariate analysis. Hyperlipidemic patients who used statins had borderline improved freedom from local failure compared with hyperlipidemic cases not using statins (P= 0.08, log-rank test). Statin use was not found to be associated with improved cancer-specific mortality.ConclusionsStatin use is independently associated with significant improvements in PFS for the overall group and PFS and OS in the hyperlipidemic group.

SummaryA retrospective study was done to determine the incidence of and the risk factors predisposing to clinical venous thromboembolism (VTE) in patients treated for high grade gliomas. Medical records of 68 consecutive patients diagnosed and treated at Saint Francis Hospital and Medical Center from January 1986 to June 1991 were reviewed. The follow up was to time of death or at least 6 months (up to December 1991). All clinically suspected episodes of VTE were confirmed by objective tests. Sixteen episodes of VTE were detected in 13 patients for an overall episode rate of 23.5%. Administration of chemotherapy (p = 0.027, two tailed Fisher exact test) and presence of paresis (p = 0.031, two tailed Fisher exact test) were statistically significant risk factors for the development of VTE. Thrombotic events were more likely to occur in the paretic limb and this difference was statistically significant (p = 0.00049, chi square test, with Yates correction). No major bleeding complications were seen in the nine episodes treated with long term anticoagulation.We conclude that venous thromboembolic complications are frequently encountered in patients being treated for high grade gliomas and the presence of paresis and the administration of chemotherapy increases the risk of such complications.

Objectives: To study the incidence, risk factors, and outcomes of conduction and rhythm disorders in a population-based cohort of patients with systemic sclerosis versus nonsystemic sclerosis comparators. Methods: An incident cohort of patients with systemic sclerosis (1980–2016) from Olmsted County, MN, was compared to age- and sex-matched nonsystemic sclerosis subjects (1:2). Electrocardiograms, Holter electrocardiograms, and a need for cardiac interventions were reviewed to determine the occurrence of any conduction or rhythm abnormalities. Results: Seventy-eight incident systemic sclerosis cases and 156 comparators were identified (mean age 56 years, 91% female). The prevalence of any conduction disorder before systemic sclerosis diagnosis compared to nonsystemic sclerosis subjects was 15% versus 7% ( p = 0.06), and any rhythm disorder was 18% versus 13% ( p = 0.33). During a median follow-up of 10.5 years in patients with systemic sclerosis and 13.0 years in nonsystemic sclerosis comparators, conduction disorders developed in 25 patients with systemic sclerosis with cumulative incidence of 20.5% (95% confidence interval: 12.4%–34.1%) versus 28 nonsystemic sclerosis patients with cumulative incidence of 10.4% (95% confidence interval: 6.2%–17.4%) (hazard ratio: 2.57; 95% confidence interval: 1.48–4.45), while rhythm disorders developed in 27 patients with systemic sclerosis with cumulative incidence of 27.3% (95% confidence interval: 17.9%–41.6%) versus 43 nonsystemic sclerosis patients with cumulative incidence of 18.0% (95% confidence interval: 12.3%–26.4%) (hazard ratio: 1.62; 95% confidence interval: 1.00–2.64). Age, pulmonary hypertension, and smoking were identified as risk factors. Conclusion: Patients with systemic sclerosis have an increased risk of conduction and rhythm disorders both at disease onset and over time, compared to nonsystemic sclerosis patients. These findings warrant increased vigilance and screening for electrocardiogram abnormalities in systemic sclerosis patients with pulmonary hypertension.

Background: There is a perception that patients with autosomal dominant polycystic kidney disease (ADPKD) are more likely to develop kidney stones than the general population. Objective: To compare the rate of hospital encounter with kidney stones and the rate of stone interventions between patients with and without ADPKD. Design: Retrospective cohort study. Setting: Ontario, Canada. Patients: Patients with and without ADPKD who had a prior hospital encounter between 2002 and 2016. Measurements: Rate of hospital encounter with kidney stones and rate of stone intervention. Methods: We used inverse probability exposure weighting based on propensity scores to balance baseline indicators of health between patients with and without ADPKD. We followed each patient until death, emigration, outcomes, or March 31, 2017. We used a Cox proportional hazards model to compare event rates between the two groups. Results: Patients with ADPKD were at higher risk of hospital encounter with stones compared with patients without ADPKD (81 patients of 2094 with ADPKD [3.8%] vs 60 patients of 1902 without ADPKD [3.2%]; 8.9 vs 5.1 events per 1000 person-years; hazard ratio 1.6 [95% CI, 1.3-2.1]). ADPKD was not associated with a higher risk of stone intervention (49 of 2094 [2.3%] vs 47 of 1902 [2.4%]; 5.3 vs 3.9 events per 1000 person-years; hazard ratio 1.2 [95% CI = 0.9-1.3]). Limitations: We did not have information on kidney stone events outside of the hospital. There is a possibility of residual confounding. Conclusion: ADPKD was a significant risk factor for hospital encounters with kidney stones.

The Impact

The prevalence of enterococcal infection, especially E. faecium, is increasing, and the issue of the impact of vancomycin resistance on clinical outcomes is controversial. This study aimed to investigate the clinical outcomes of infection caused by E. faecium and determine the risk factors associated with mortality. This retrospective study was performed at the Phramongkutklao Hospital during the period from 2014 to 2018. One hundred and forty-five patients with E. faecium infections were enrolled. The 30-day and 90-day mortality rates of patients infected with vancomycin resistant (VR)-E. faecium vs. vancomycin susceptible (VS)-E. faecium were 57.7% vs. 38.7% and 69.2% vs. 47.1%, respectively. The median length of hospitalization was significantly longer in patients with VR-E. faecium infection. In logistic regression analysis, VR-E. faecium, Sequential Organ Failure Assessment (SOFA) scores, and bone and joint infections were significant risk factors associated with both 30-day and 90-day mortality. Moreover, Cox proportional hazards model showed that VR-E. faecium infection (HR 1.91; 95%CI 1.09–3.37), SOFA scores of 6–9 points (HR 2.69; 95%CI 1.15–6.29), SOFA scores ≥ 10 points (HR 3.71; 95%CI 1.70–8.13), and bone and joint infections (HR 0.08; 95%CI 0.01–0.62) were significant risk factors for mortality. In conclusion, the present study confirmed the impact of VR-E. faecium infection on mortality and hospitalization duration. Thus, the appropriate antibiotic regimen for VR-E. faecium infection, especially for severely ill patients, is an effective strategy for improving treatment outcomes.

Risk Of Death

Endometrial cancer (EC) is the most common gynecologic malignancy in Sweden and it has various prognostic factors. The LRIG family is a group of three integral surface proteins with a similar domain organization. The study aimed to explore LRIG family as prognostic factor proteins in EC. The initial study cohort included 100 women with EC who were treated at the Department of Women’s and Children’s Health, Karolinska University Hospital Solna, between 2007 and 2012. We assessed the associations between LRIG protein expression and type, grade, and stage of EC, as well as progression-free and overall survival. Immunohistochemistry results revealed that most women in the analytical sample had >50% LRIG1-, LRIG2- and LRIG3-positive cells. A statistically significant association was observed between having a high number of LRIG3-positive cells and superior overall survival (incidence rate ratio = 0.977; 95% confidence interval: 0.958–0.996, p = 0.019). Moreover, positive LRIG3 staining of the cell membrane was associated with reducing in the risk of death (hazard ratio = 0.23; 95% confidence interval: 0.09–0.57). Our results show that LRIG3 expression might be a prognostic factor in EC. The role of LRIG1 and LRIG2 expression remains to be further investigated.

Hcc Recurrence

Abstract Background An unexpected recurrence of hepatocellular carcinoma (HCC) sometimes occurs in patients with hepatitis C virus (HCV) after treatment with direct-acting antivirals (DAAs). However, the characteristics of patients with HCC recurrence may differ depending on time after DAA treatment. We aimed to identify risk factors related to HCC recurrence according to time after DAA treatment. Methods Of 1663 patients with HCV treated with a DAA, 199 patients had a previous history of HCC. We defined HCC recurrence within 1 year after DAA treatment as ‘early recurrence’, and recurrence more than 1 year after as ‘late recurrence’. The different risk factors between the early and late phases of HCC recurrence after the end of DAA therapy were investigated. Results Ninety-seven patients experienced HCC recurrence during the study period. Incidences of recurrence were 29.8, 41.0, and 53.4% at 1, 2, and 3 years, respectively, after the end of DAA therapy. Multivariate analysis identified post-treatment α-fetoprotein (AFP) as an independent factor contributing to HCC recurrence in the early phase (hazard ratio, 1.056; 95% confidence interval, 1.026–1.087, p < 0.001) and post-treatment estimated glomerular filtration rate (eGFR) (hazard ratio, 0.98; 95% confidence interval, 0.96–0.99, p = 0.032) as a predictor of HCC recurrence in the late phase. Conclusion Patients with higher post-treatment AFP in the early phase and those with lower post-treatment eGFR in the late phase had a high risk of HCC recurrence. The risk factors associated with HCC recurrence after DAA treatment were different between the early and late phases.
