AimsDiabetes increases the risk of costly and potentially preventable hospital-acquired pressure ulceration. Given that peripheral arterial disease and neuropathy, important risk factors for foot ulceration, are more common in people with diabetes, their risk of hospital-acquired foot ulceration (HAFU) in particular may be even greater. This study aims to determine this risk.MethodsUsing data collected over 2 years from all admissions to the Ipswich Hospital NHS Trust, we conducted a prospective multilevel regression analysis of the risk of HAFU in 5043 admissions of people with diabetes versus 23 599 without diabetes. Patients over 50 years who developed HAFU at least 48 hours after admission were included in analyses. Progressive adjustment for important risk factors and subgroup analyses were conducted to compare patients with and without diabetes.ResultsThere were significant differences between patients with and without diabetes among a range of covariates including sex, Comorbidity Score, and length of stay (p value <0.001). After progressive adjustment for age, sex, and other risk factors, there persisted a significant increase risk of HAFU in people with diabetes (OR 2.24; 95% CI 1.80 to 2.69). There were no substantial differences between clinically relevant subgroups.ConclusionsThese analyses demonstrate at least a twofold increase in the risk of HAFU in patients with diabetes and suggest further work should focus on specific processes to detect those inpatients with diabetes at increased risk, in whom preventative measures may reduce the prevalence of this costly complication.

Abstract Background Elevated lipoprotein (a) [LP (a)] levels are an independent, genetic, and causal factor for cardiovascular disease and associated with myocardial infarction (MI). Although the association between circulating levels of lipoprotein(a) [Lp(a)] and risk of coronary artery disease (CAD) is well established, its role in risk of peripheral arterial disease (PAD) remains unclear. PAD affects over 236 million individuals and follows ischaemic heart disease (IHD) and cerebrovascular disease (CVD) as the third leading cause of atherosclerotic cardiovascular morbidity worldwide. LP (a) is genetically determined, stable throughout life and yet refractory to drug therapy. While 30 mg/dl is considered the upper normal value for LP (a) in central Europe, extremely high LP (a) levels (&gt;150mg/dl) are rare in the general population. The aim of our study was to analyse the correlation between lipoprotein (a) [LP (a)] levels and an incidence of PAD in high-risk patients. Patients and methods We reviewed the LP (a) concentrations of 52.898 consecutive patients admitted to our cardiovascular center between January 2004 and December 2014. Of these, 579 patients had LP (a) levels above 150 mg/dl (mean 181.45±33.1mg/dl). In the control collective LP (a) was &lt;30mg/dl (n=350). Other atherogenic risk factors in this group were HbA1c 6.58±1.65%, low density lipoprotein (LDL) 141.99±43.76 mg/dl, and body mass index 27.81±5.61. 54.40% were male, 26.07% were smokers, 93.2% had hypertension, and 24% had a family history of cardiovascular diseases. More than 82.6% were under statins. The mean glomerular filtration rate (GFR) was 69.13±24.8 ml/min [MDRD (Modification of Diet in Renal Disease)]. Results 45.00% (n=261) of the patients with LP (a) &gt;150mg/dl had PAD. The prevalence of PAD in patients with LP (a) &lt;30mg/dl in our control collective was 15.8%. (P- Value 0.001). Patients with LP (a) &gt;150mg/dl had a significantly increased risk for PAD (Odds ratio 4.36, 95% CI 2.94–6.72, p: 0.001). 19.1% of patients were re-vascularized by percutaneous angioplasty (PTA) and 7.09% of patients had to undergo peripheral vascular bypass (PVB). Mean LP (a) level in patients with PAD was 182.6±31.61. Conclusion Elevated LP (a) levels above 150 mg/dl are associated with a significantly increased risk of PAD in our collective and it confirms our hypothesis. Over one fourth of these patients had severe PAD and requiring revascularization therapy. We need more prospective studies to confirm our findings.

Background: To investigate the relationship between pleural empyema (PE) and peripheral arterial disease (PAD).Methods: We conducted a retrospective cohort study using data from the National Health Institute Research Database. Univariable and multivariable Cox's proportional hazard regressions were performed to investigate the association between PE and the risk of PAD. Kaplan–Meier method and the differences were assessed using a log-rank test.Results: The overall incidence of PAD was higher in the PE cohort than in the non-PE cohort (2.76 vs. 1.72 per 1,000 person-years) with a crude hazard ratio (HR) of 1.61 [95% confidence interval (CI) = 1.41–1.83]. After adjustment for age, gender, and comorbidities, patients with PE were noted to be associated with an increased risk of PAD compared with those without PE [adjusted HR (aHR) = 1.18, 95% CI = 1.03–1.35]. Regarding the age-specific comparison between the PE and non-PE cohorts, PAD was noted to be significantly high in the ≤ 49 years age group (aHR = 5.34, 95% CI = 2.34–10.1). The incidence of PAD was higher in the first 2 years, with an aHR of 1.35 (95% CI = 1.09–1.68) for patients with PE compared with those without PE.Conclusion: The risk of PAD was higher if patients with PE were younger than 49 years and within the 2-year diagnosis of PE.

Abstract Background Peripheral arterial disease is a marker of aggressive atherosclerosis. The ankle brachial index (ABI) is a simple and non-invasive tool to diagnose peripheral arterial disease (PAD). Patients with PAD are at increased risk for ischemic strokes and other cardiovascular diseases. Purpose To evaluate the association of abnormal ABI and poorly compressible vessels with ischemic stroke in a large patient cohort. Methods We analyzed lower extremity vascular studies of all patients with ABI measurements at a tertiary care hospital between January 1996 and August 2018. PAD is defined as ABI<1.0, and poorly or non-compressible (PC/NC) arteries as ABI>1.4 while ABI between 1.0–1.4 is normal. Association of these ABIs with new ischemic stroke events post ABI measurement were analyzed after adjusting for high risk confounders such as atrial fibrillation. Hazard ratios (HR) were calculated using multivariable Cox proportional regression with 95% confidence intervals. Results In total, 38,016 unique patients (mean age 66.1±14.8 years, female 42.3%) were included. Abnormal ABI was found to be more prevalent among elderly male patients compared to patients with normal ABI. In contrast to non-PAD patients, both PAD and PC/NC patients as defined by ABI had a statistically significant risk of ischemic stroke, with PAD conferring the greatest risk compared to PC/NC vessels. The data is summarized in Table 1. Table 1 Unadjusted HR p-value Adjusted HR p-value PAD vs. No PAD 2.77 (2.62, 2.92) <0.001 2.10 (1.98, 2.22) <0.001 PC/NC vs. No PAD 2.11 (1.95, 2.28) <0.001 1.38 (1.26, 1.51) <0.001 PAD vs. PC/NC 1.37 (1.28, 1.46) <0.001 1.37 (1.28, 1.48) <0.001 Adjusted and unadjusted hazard ratios with p-values. HR adjusted for age, sex, atrial fibrillation, ischemic stroke, transient ischemic attack, chronic heart failure, diabetes mellitus, hyperlipidemia, hypertension, and coronary artery disease. PAD = Peripheral artery disease and PC/NC = poorly compressible/non-compressible. Conclusion This study adds to the growing body of evidence that PAD and poorly-compressible vessels are independently associated with an increased risk of ischemic stroke. Given the associated risk of cerebrovascular disease, clinicians should aggressively treat to minimize risk factors in those with abnormal ABIs.

Objective.Whether systemic sclerosis (SSc) confers increased risk of venous thromboembolism (VTE) is uncertain. We evaluated the prevalence, risk factors, and effect of VTE on SSc survival.Methods.A cohort study was conducted of subjects with SSc who fulfilled the American College of Rheumatology/European League Against Rheumatism classification criteria between 1970 and 2017. Deep vein thrombosis was defined as thrombus on extremity ultrasound. Pulmonary embolism was defined as thrombus on thorax computed tomography angiogram. Risk factors for VTE and time to all-cause mortality were evaluated.Results.Of the 1181 subjects, 40 (3.4%) experienced VTE events. The cumulative incidence of VTE was 2.7 (95% CI 1.9–3.7) per 1000 patient-years. Pulmonary arterial hypertension (PAH; OR 3.77, 95% CI 1.83–8.17), peripheral arterial disease (OR 5.31, 95% CI 1.99–12.92), Scl-70 (OR 2.45, 95% CI 1.07–5.30), and anticardiolipin antibodies (OR 5.70, 95% CI 1.16–21.17) were predictors of VTE. There were 440 deaths. There was no difference in survival between those with and without VTE (HR 1.16, 95% CI 0.70–1.91). Interstitial lung disease (HR 1.54, 95% CI 1.27–1.88) and PAH (HR 1.35, 95% CI 1.10–1.65) were predictors of mortality.Conclusion.The risk of VTE in SSc is comparable to the general population. The presence of PAH, peripheral arterial disease, Scl-70, and anticardiolipin antibodies are risk factors for VTE. VTE does not independently predict SSc survival.

Introduction: Peripheral arterial disease (PAD) shares several risk factors with atrial fibrillation (AF) and persons with PAD have an increased risk of stroke. It is unclear if PAD is associated with an increased risk for AF and whether such an association explains the increased risk of stroke associated with PAD. Methods: We examined the association between PAD, as measured by the ankle-brachial index (ABI), and incident AF and incident stroke, separately, in 6,568 participants (mean age 62 ± 10; 53% women; 62% non-white) from the Multi-Ethnic Study of Atherosclerosis (MESA). ABI values <1.0 or >1.4 defined PAD in this analysis. Participants were free of baseline clinical cardiovascular disease and AF. AF was ascertained by review of hospital discharge records and from Medicare claims data until December 31, 2010. An independent adjudication committee ascertained stroke events. Cox regression was used to compute hazard ratios (HR) and 95% confidence intervals (95%CI) for the association between PAD and AF and stroke. Results: A total of 774 (12%) participants had baseline PAD. Over a median follow-up of 8.5 years, 301 (4.6%) participants developed AF and 140 (2.1%) developed stroke. In a model adjusted for socio-demographics, cardiovascular risk factors, and potential confounders, PAD was associated with an increased risk of AF (HR=1.5, 95%CI=1.1, 2.0). In a similar model, PAD was associated with incident stroke (HR=1.7, 95%CI=1.1, 2.5) and the magnitude of risk was not different after inclusion of AF as a time-dependent covariate (HR=1.7, 95%CI=1.1, 2.5). Similar results were obtained in subgroup analyses stratified by age, sex, and race/ethnicity. Conclusions: PAD is independently associated with an increased risk of AF and stroke in the MESA study. The relationship between PAD and stroke is not mediated by AF.

383 Background: Venous thromboembolism (VTE) is a frequent complication of cancer or its treatment. Khorana (KRS) and Compass scores are two Risk Assessment Models for VTE. However, aUTC was not adequately represented and arterial events were not included, in these models. Methods: Data from pts with aUTC treated with at least one line of chemotherapy in our institution were analyzed. VaTE definition included: DVT and PE defined as venous events and peripheral arterial thrombosis or embolus, ischemic stroke and coronary events, grouped as arterial events. The association of baseline and treatment-related factors with the development of VaTE was assessed using competing-risk regressions. According to the results of our multivariate analysis we stratified patients according to the number of the identified risk factors. Results: 354 aUTC pts treated between 4/1995 and 9/2015 entered our study. 53% of pts had received cisplatin and 42% carboplatin-based regimens. 44 pts (12.4%) suffered 45 VaTEs (13 arterial, 32 venous) within a median time of 3.3 months. The cumulative and 6-month incidence was 14.8% (95% CI: 10.9-19.4) and 9.7% (95% CI: 6.8-13.1), [venous 10.5% (95% CI: 7.3-14.3)/7.5% (95% CI: 5-10.7); arterial 5.3% (95% CI: 2.8-9)/2.7% (95% CI: 1.3-5), respectively]. No association of the KRS and the COMPASS score with the incidence of VaTEs was observed. In the univariate and multivariate analysis, cumulative VaTE incidence was significantly increased in pts with “peripheral arterial disease (PAD) or history of VΤE” (adjusted SHR: 3.29; 95% CI: 1.65-6.55; p=0.001) and pts with other solid tumor (SHR: 2.20; 95% CI: 1.05-4.62; p=0.038). There was a strong correlation between the number of risk factors and the risk for VaTE development (p<0.001). Patients with 1 or 2, vs 0 factors had a 3-fold increased risk [cumulative incidence was 10.9% (95% CI: 7.4.-15.2) and 30.2% (95% CI: 18.4-42.8), respectively; SHR: 3.01 95% CI: 1.65-5.51]. Conclusions: Development of tumor-specific algorithms for the risk of vascular events is supported by our results. Pts with aUTC and a history of VTE, PAD and other solid tumor have a very high risk for VaTE. The role of prophylaxis should be prospectively studied.

Background Mortality among patients with hospital-acquired pneumonia (HAP) is quite high; however, information on risk factors for short-term mortality in this population remains limited. The aim of the current study was to identify the risk factors for mortality in bedridden patients with HAP during a 3-month observation period. Methods A secondary data analysis was conducted. In total, 1141 HAP cases from 25 hospitals were included in the analysis. Univariate and multilevel regression analyses were performed to identify the risk factors for mortality. Results During the 3-month observation period, there were 189 deaths among bedridden patients with HAP. The mortality rate in this study was 16.56%. Multilevel regression analysis showed that ventilator-associated pneumonia (OR = 2.034, 95%CI: 1.256, 3.296, p = 0.004), pressure injuries (OR = 2.202, 95%CI: 1.258, 3.852, p = 0.006), number of comorbidities (OR = 1.076, 95%CI: 1.016,1.140, p = 0.013) and adjusted Charlson Comorbidity Index score (OR = 1.210, 95%CI: 1.090, 1.343, p<0.001) were associated with an increased risk of mortality, while undergoing surgery with general anaesthesia (OR = 0.582, 95%CI: 0.368, 0.920, p = 0.021) was associated with a decreased risk of mortality. Conclusions The identification of risk factors associated with mortality is an important step towards individualizing care plans. Our findings may help healthcare workers select high-risk patients for specific interventions. Further study is needed to explore whether appropriate interventions against modifiable risk factors, such as reduced immobility complications or ventilator-associated pneumonia, could improve the prognoses.
