Abstract Background Patients with diabetes are at increased risk of developing chronic limb-threatening ischemia (CLTI) due to peripheral arterial disease, and this often results in lower extremity amputation (LEA). Little is known of the interaction between diabetes and other vascular risk factors in affecting the risk of CLTI. Methods We investigated the association of diabetes, and its interaction with hypertension, body mass index (BMI) and smoking, with the risk of LEA due to CLTI in the population-based Singapore Chinese Health Study. Participants were interviewed at recruitment (1993–1998) and 656 incident LEA cases were identified via linkage with nationwide hospital database through 2017. Multivariate-adjusted Cox proportional hazards models were used to compute hazard ratios (HRs) and 95% CIs for the associations. Results The HR (95% CI) for LEA risk was 13.41 (11.38–15.79) in participants with diabetes compared to their counterparts without diabetes, and the risk increased in a stepwise manner with duration of diabetes (P for trend < 0.0001). Hypertension and increased BMI independently increased LEA risk in those without diabetes but did not increase the risk in those with diabetes (P for interaction with diabetes ≤ 0.0006). Conversely, current smoking conferred a risk increment of about 40% regardless of diabetes status. Conclusions Although diabetes conferred more than tenfold increase in risk of LEA, hypertension and increased BMI did not further increase LEA risk among those with diabetes, suggesting a common mechanistic pathway for these risk factors. In contrast, smoking may act via an alternative pathway and thus confer additional risk regardless of diabetes status.

Introduction: Cerebral vein thrombosis (CVT) is associated with an increased risk of subsequent venous thromboembolism. It is unknown whether the risk of pulmonary embolism (PE) after CVT is similar to that of PE after deep venous thrombosis (DVT). Methods: We performed a retrospective cohort study using administrative claims data from all emergency department visits and hospitalizations in California from 2005-2011, New York from 2006-2013, and Florida from 2005-2013. We identified patients with CVT or DVT as well as the primary outcome of PE using previously validated International Classification of Diseases, Ninth Revision, Clinical Modification ( ICD-9-CM ) codes. In order to minimize misclassification error, patients with both CVT and DVT during the same index hospitalization were excluded and patients with CVT were censored at the time of development of DVT and vice versa. Kaplan-Meier survival statistics and Cox proportional hazards models were used to compare the risk of PE after CVT versus after DVT while adjusting for demographics, vascular risk factors, and the Elixhauser comorbidity index. Results: We identified 4,450 patients with CVT and 217,589 patients with DVT. During a mean follow-up of 2.0 (±1.7) years, 124 patients with DVT developed a PE and 18,698 patients with DVT developed a PE. Patients with CVT were younger (mean age 45 vs 63), more often female (71% vs 52%), more often pregnant, and had fewer vascular risk factors than patients with DVT. During the index hospitalization, the rate of PE was 1.5% (95% confidence interval [CI], 1.1-1.8%) in patients with CVT and 6.2% (95% CI, 6.1-6.3%, p<0.001) in patients with DVT. By 5 years, the cumulative rate of PE after CVT was 3.7% (95% CI, 3.0-4.4%) compared to 10.5% (95% CI, 10.3-10.6%, p<0.001) after DVT. After adjustment for demographics and comorbidities, CVT was associated with a significantly lower hazard of PE when compared to DVT (hazard ratio, 0.31; 95% CI, 0.26-0.38). Conclusion: In a large, heterogeneous population, we found that the risk of PE after CVT was significantly lower than that of PE after DVT. Among patients with CVT, the greatest risk for PE was apparent during the index hospitalization.

Abstract BACKGROUND Patients with high-grade gliomas (HGG) often receive anti-angiogenic therapy with bevacizumab to slow disease progression and/or palliate neurological symptoms. Bevacizumab has been associated with an increased risk of two major vascular complications: venous thromboembolism (VTE) and intracranial hemorrhage (ICH). We sought to identify clinical, pathologic, and radiographic variables correlated with risk of either event occurring in patients with HGG receiving bevacizumab. METHODS We retrospectively identified 94 patients with HGG who received bevacizumab at our center from 2015-2021. Variables included demographics, performance status, IDH, MGMT, vascular risk factors, baseline anti-coagulant/anti-platelet use, concurrent chemotherapy, and presence of macrobleeds on MRI (&gt;1 cm3 susceptibility) at the time of bevacizumab initiation. We conducted competing risk analysis using subdistribution hazard models with death as competing risk for ICH or VTE. The effects of covariates on the incidence of hemorrhage or VTE were evaluated in univariate and multivariate settings. RESULTS Of 94 patients, 36 (38.3%) and 27 (28.7%) developed VTE and ICH, respectively. 31 (33%) did not develop either. ICH and VTE events occurred after a mean of 4.46 and 5.94 cycles of bevacizumab, respectively. 20 had baseline anti-platelet/anticoagulant use, and 16 had prior VTEs. Patients with macrobleeds on MRI had a larger HR of developing acute hemorrhage [HR=2.368 (1.112, 5.043), p=0.0254]. Patients older than 50 trended toward larger HR of developing VTE in univariate analysis that approached significance [HR=1.799 (0.889, 3.637), p=0.1023]. Sex, performance status, IDH, MGMT, vascular risk factors, baseline anticoagulant/anti-platelet use and concurrent chemotherapy were not significantly associated with occurrence of VTE. CONCLUSIONS The presence of macrobleeds on MRI is associated with increased risk of developing acute ICH while on bevacizumab. Older age at diagnosis of HGG may be associated with an increased risk of VTE in patients receiving bevacizumab. Larger studies are needed to confirm these findings.

Abstract Purpose of review To elucidate the intertwining of vascular events, vascular disease and vascular risk factors and COVID-19. Recent findings Strokes are a leading cause of disability and death worldwide. Vascular risk factors are important drivers of strokes. There are unmodifiable vascular risk factors such as age and ethnicity and modifiable vascular risk factors. According to the INTERSTROKE study, the 10 most frequent modifiable vascular risk factors are arterial hypertension, physical inactivity, overweight, dyslipidaemia, smoking, unhealthy diet, cardiac pathologies, diabetes mellitus, stress/depression and overconsumption of alcohol. Also, infection and inflammation have been shown to increase the risk of stroke. There is high-quality evidence for the clinical benefits of optimal primary and secondary stroke prevention. The COVID-19 pandemic brought a new perspective to this field. Vascular events, vascular disease and vascular risk factors—and COVID-19—are strongly intertwined. An increased risk of vascular events—by multifactorial mechanisms—has been observed in COVID-19 patients. Also, a higher rate of infection with COVID-19, severe COVID-19 and bad outcome has been demonstrated in patients with pre-existing vascular disease and vascular risk factors. Summary At present, we suggest that regular interactions between healthcare professionals and patients should include education on COVID-19 and on primary and secondary vascular prevention in order to reduce the burden of disease in our ageing populations.
