ABSTRACT

Venous thromboembolism (VTE) and major bleeding in primary central nervous system lymphoma (PCNSL) patients are not well described. We identified 992 PCNSL patients using the California Cancer Registry (2005-2014). The cumulative incidence of VTE and major bleeding was determined using California hospitalization data. The 12-month cumulative incidence of VTE was 13.6% (95% confidence interval (CI) 11.5-15.8%); chemotherapy and radiation therapy were associated with increased risk of VTE (hazard ratio (HR) 2.41, CI 1.31-4.46 and HR 1.56, CI 1.08-2.25, respectively). The 12-month cumulative incidence of major bleeding was 12.4% (CI 10.1-14.6%). Pulmonary embolism (PE) and proximal deep vein thrombosis were associated with increased risk of major bleeding, likely due to anticoagulation. PE (HR 1.61, CI 1.11-2.33, p=.011) and major bleeding (HR 2.36, CI 1.82-3.06, p<.0001)

Whole milk consumption is associated with lower risk of coronary artery calcification progression: evidences from the Multi-Ethnic Study of Atherosclerosis

Ghosh S, et al. Eur J Nutr 2020.

ABSTRACT

PURPOSE: Coronary artery calcification (CAC) progression is a strong predictor of cardiovascular disease (CVD) morbidity and mortality. However, the association between whole milk and CAC progression remains unknown. Recent studies highlighted beneficial effects of short chain fatty acids (SCFA) from whole milk on CVD. In this study, we attempted to investigate the relationship between whole milk consumption and CAC progression, and the potential effect of SCFA in it.

METHODS: We analyzed a population-based cohort with 5273 participants from the Multi-Ethnic Study of Atherosclerosis (MESA) who completed a dietary questionnaire at baseline. CAC was measured at baseline and subsequent follow-up examinations by multi-detector computed tomography (MDCT) scans with Agatston scores. CAC progression was defined as increased CAC scores in the follow-up from the baseline exam.

RESULTS: Participants consuming whole milk exhibited lower baseline CAC and CAC progression than those who never/rarely consumed whole milk (P < 0.001 and P = 0.010, respectively). Moreover, multivariable logistic regression analysis demonstrated that whole milk intake was independently associated with lower CAC progression (OR 0.765; 95% CI 0.600-0.977; P = 0.032), especially in males, participants with age ≤ 64 years and with body mass index (BMI) ≤ 25 kg/m2. Mediation analysis further showed that caproic acid, one kind of SCFA, partly mediated protective effects of whole milk on CAC progression.

CONCLUSIONS: Self-reported whole milk consumption was inversely associated with CAC progression in community-dwelling participants, especially in those at relatively low cardiovascular risks. The beneficial effect was partially mediated by SCFA. Therefore, whole milk can be incorporated into part of a cardio-protective diet. Regarding this, future studies may target SCFA to provide insight into more mechanistic views.

Dual mechanical and pharmacological thromboprophylaxis decreases risk of pulmonary embolus after laparotomy for gynecologic malignancies

Nguyen JMV, et al. Int J Gynecol Cancer 2020.

ABSTRACT

OBJECTIVES: Patients with gynecologic malignancies have high rates of post-operative venous thromboembolism. Currently, there is no consensus for peri-operative thromboprophylaxis specific to gynecologic oncology. We aimed to compare rates of symptomatic pulmonary embolus within 30 days post-operatively, and to identify risk factors for pulmonary embolus.

METHODS: The Division of Gynecologic Oncology at Sunnybrook Health Sciences Centre implemented dual thromboprophylaxis for laparotomies in December 2017. We conducted a prospective study of laparotomies for gynecologic malignancies from December 2017 to October 2018, with comparison to historical cohort from January 2016 to November 2017 using the institutional National Surgical Quality Improvement Program database (NSQIP). Pre-intervention, patients received low molecular weight heparin during admission and extended 28-day prophylaxis was continued at the surgeon's discretion. Post-intervention, all patients received both mechanical thromboprophylaxis with sequential compression devices during admission and 28-day prophylaxis with low molecular weight heparin.

RESULTS: There were 371 and 163 laparotomies pre- and post-intervention, respectively. Patient characteristics (age, body mass index, diabetes, smoking, tumor stage), rate of malignant cases, operative blood loss and duration, and length of stay were similar between groups. After implementation, pulmonary emboli rates decreased from 5.1% to 0% (p=0.001). There were more cytoreductive procedures pre-intervention (p≤0.0001) but surgical complexity scores were similar (p=0.82). Univariate analysis revealed that surgery pre-intervention (OR 4.25, 95% CI 1.04 to 17.43, p=0.04), length of stay ≥5 days (OR 11.94, 95% CI 2.65 to 53.92, p=0.002), and operative blood loss ≥500 mL (OR 2.85, 95% CI 1.05 to 7.8, p=0.04) increased risk of pulmonary embolus. On multivariable analysis, surgery pre-intervention remained associated with more pulmonary emboli (OR 4.16, 95% CI 1.03 to 16.79, p=0.045), when adjusting for operative blood loss.

CONCLUSION: Dual thromboprophylaxis after laparotomy significantly reduced rates of pulmonary embolus in this high-risk patient population.

In vivo performance of gold nanoparticle-loaded absorbable inferior vena cava filters in a swine model

Huang SY, et al. Biomater Sci 2020.

ABSTRACT

Absorbable inferior vena cava filters (IVCFs) offer a promising alternative to metallic retrievable filters in providing protection against pulmonary embolism (PE) for patients contraindicated for anticoagulant therapy. However, because absorbable filters are not radiopaque, monitoring of the filter using conventional X-ray imaging modalities (e.g. plain film radiographs, computed tomography [CT] and fluoroscopy) during deployment and follow-up is not possible and represents a potential obstacle to widespread clinical integration of the device. Here, we demonstrate that gold nanoparticles (AuNPs) infused into biodegradable filters made up of poly-p-dioxanone (PPDO) may improve device radiopacity without untoward effects on device efficacy and safety, as assessed in swine models for 12 weeks. The absorbable AuNP-infused filters demonstrated significantly improved visualization using CT without affecting tensile strength, in vitro degradation, in vivo resorption, or thrombus-capturing efficacy, as compared to similar non-AuNPs infused resorbable IVCFs. This study presents a significant advancement to the development of imaging enhancers for absorbable IVCFs.

Gender differences in quality of life in coronary artery disease patients with comorbidities undergoing coronary revascularization

Oreel TH, et al. PLoS One 2020.

ABSTRACT

In comparison to male patients with coronary artery disease, female patients suffer from more comorbidities, experience symptoms of coronary artery disease differently and report poorer health-related quality of life (HRQoL) after coronary revascularization. However, there is limited data on the impact of comorbidity burden on the recovery in HRQoL in female and male patients. We investigated the impact of comorbidity burden on the change in HRQoL following coronary revascularization in female patients versus male patients. 230 patients (60 female) with coronary artery disease were assessed before, and two weeks, three months and six months after coronary revascularization. Disease-specific HRQoL was measured with the Short-Form Seattle Angina Questionnaire. Physical and mental health was measured with the Short-Form Health Survey. Comorbidity burden was assessed by the total number of identified comorbidity conditions and by the Charlson comorbidity score. Linear mixed models were used to estimate the effects of time, gender and comorbidity burden on HRQoL. Whereas HRQoL improved after coronary revascularization in all patients, female patients reported poorer physical health and disease-specific HRQoL and their physical health improved more slowly than male patients. A higher comorbidity burden was related with poorer physical health and disease-specific HRQoL in male patients, but not in female patients. A higher comorbidity burden was associated with slower improvement in HRQoL for both female and male patients. Female patients reported poorer HRQoL and their physical health improved more slowly after coronary revascularization, irrespective of comorbidity burden. Higher comorbidity burden was associated with poorer physical health and disease-specific HRQoL in male patients only. Our results indicate that female and male patients recover differently after coronary revascularization. These findings highlight the importance of comorbidity- and gender-specific approaches for evaluating coronary artery disease and coronary revascularization procedures.
