As the Coronavirus disease 2019 (COVID-19) pandemic spread to the US, so too did descriptions of an associated coagulopathy and thrombotic complications. Hospitals created institutional protocols for inpatient management of COVID-19 coagulopathy and thrombosis in response to this developing data. We collected and analyzed protocols from 21 US academic medical centers developed between January and May 2020. We found greatest consensus on recommendations for heparin-based pharmacologic venous thromboembolism (VTE) prophylaxis in COVID-19 patients without contraindications. Protocols differed regarding incorporation of D-dimer tests, dosing of VTE prophylaxis, indications for post-discharge pharmacologic VTE prophylaxis, how to evaluate for VTE, and the use of empiric therapeutic anticoagulation. selleckchem These findings support ongoing efforts to establish international, evidence-based guidelines.
Venous thromboembolism (VTE) is common in non-small cell lung cancer (NSCLC) patients undergoing systemic chemotherapy. The usefulness of Khorana score (KRS) to predict risk in lung cancer patients is limited, and the identification of patients who would benefit most from thromboprophylaxis is challenging. We aimed to identify variables whose values before chemotherapy helped in predicting VTE occurrence, and build a model to assess VTE risk.

A cohort of newly diagnosed NSCLC patients to undergo outpatient chemotherapy, not under anticoagulant treatment, was recruited. Pre-chemotherapy demographic, clinical, analytical and tumor-specific variables were collected. Patients were prospectively followed-up for 12 months to record VTE events. Bivariate and multivariate analyses were performed to identify VTE-associated variables, and a prediction model was built and compared with KRS.

90 patients were recruited, 18 of whom had a VTE event during follow-up. High baseline levels of factor VIII (FVIII) and, especially, soluble P-selectin (sP-selectin), were independently associated with VTE risk (hazard ratio [HR] 4.15, 95% confidence interval [CI] 1.17-14.71, and 66.40 [8.70-506.69], respectively). Our so-called Thrombo-NSCLC risk score, which assigns 1 and 3 points to high FVIII and sP-selectin values, respectively, was significantly better than KRS in predicting VTE (area under the curve [AUC] 0.93 vs. 0.55, sensitivity 94.4 vs. 35.0%, specificity 93.1 vs. 60.0%). Our prediction model showed significant discriminating capacity between high risk vs. intermediate/low risk patients, while KRS did not.

The Thrombo-NSCLC risk score may be useful to identify those NSCLC patients who would benefit most from thromboprophylaxis.

Post-thrombotic syndrome (PTS) is a burdensome long-term complication of deep vein thrombosis (DVT). Recent studies have suggested that rivaroxaban may reduce PTS events compared to vitamin-K antagonists (VKAs). We, therefore, systematically reviewed available literature that compared rivaroxaban versus VKAs on the risk of PTS.

We conducted a systematic review and meta-analysis using PubMed, EMBASE and Cochrane Library for all related studies from inception until March 2020. Two reviewers independently screened studies, extracted data, and appraised the quality of included studies. The primary outcome was overall risk of PTS. The secondary outcomes were risks of each PTS category (mild, moderate, severe) and venous ulcer.

Seven comparative studies, comprising 2364 participants, qualified for this meta-analysis. The use of rivaroxaban for DVT treatment was associated with a lower risk of PTS compared with conventional VKAs [pooled unadjusted odds ratio (OR) 0.53, 95%CI 0.43-0.65, P<0.00001]. This effect was maintained after adjustment of potential confounders (pooled adjusted OR 0.44, 95%CI 0.35-0.56, P<0.00001). Furthermore, rivaroxaban therapy was found to be associated with reduced risk of mild PTS (OR 0.64, 95%CI 0.50-0.82, P=0.0005), moderate PTS (OR 0.64, 95%CI 0.45-0.91, P=0.01), and severe PTS (OR 0.52, 95%CI 0.33-0.82, P=0.005). There was also a similar trend towards reduced risk for venous ulcer, albeit not statistically significant (OR 0.41, 95%CI 0.15-1.08, P=0.07).

In comparison to VKAs, the use of rivaroxaban for DVT treatment has the potential to reduce PTS events. However, well-designed studies with larger sample sizes are needed to corroborate these findings.

Thrombotic thrombocytopenic purpura (TTP) is a life-threatening thrombotic microangiopathy (TMA) that requires prompt plasma exchange. Clinical prediction tools may facilitate decision-making in institutions with delayed turnaround time or limited access to ADAMTS13 assays. The PLASMIC score and Bentley score have been shown to predict severe ADAMTS13 deficiency with excellent sensitivity and specificity.

To validate the PLASMIC score using a population of suspected TTP, and evaluate its discriminatory power in predicting severe ADAMTS13 deficiency in comparison with Bentley score and clinical gestalt.

Adults presenting with suspected TTP in Alberta, Canada between 2008 and 2018 with available ADAMTS13 results were included. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated for PLASMIC score, Bentley score and clinical gestalt. Receiver operator characteristics analysis assessed the performance of the scoring systems.

This meta-analysis aimed to identify the risk factors for venous thromboembolism (VTE) in patients with gynecological malignancy during the perioperative period.

Studies on the risk factors for VTE in patients with gynecological malignancy during the perioperative period were collected from the Cochrane Library, MEDLINE, EMBASE, Web of Science, EBSCO, and several Chinese databases (from inception to September 2019). Two reviewers independently performed article screening, data extraction, and study quality evaluation. Review Manager 5.3 software was used for data analysis.

A total of 9555 articles were initially retrieved, including 7498 in Chinese and 1987 in English, and 22 articles were finally included, which were published from 2011 to 2019. The quality scores of the included studies ranged from 5 to 9, suggesting a relatively high quality. A total of 16,318 patients were included for analysis, 922 in the VTE group and 15,396 in the non-VTE group. A total of 20 risk factors related to surgery or with inconsistent conclusions in the current studies were pooled, and the results showed that age, body mass index (BMI > 26 kg/m
), platelet count, D-dimer, duration of surgery, postoperative days in bed, length of hospital stay, intraoperative blood loss, tumor differentiation (GREAD3), tumor staging (stage IV), and operative approach (laparotomy versus laparoscopy) were significant risk factors for VTE in patients with gynecological malignancy during the perioperative period.
