Abstract Background: Carbapenem-resistant Klebsiella pneumoniae bloodstream infections (CRKP-BSIs) are associated with high morbidity and mortality rates, especially in critically ill patients. Comprehensive mortality risk analyses and therapeutic assessment in real-world practice are beneficial to guide individual treatment.Methods: We retrospectively analyzed 87 patients with CRKP-BSIs (between July 2016 and June 2020) to identify the independent risk factors for 28-day all-cause mortality. The therapeutic efficacies of tigecycline-and polymyxin B-based therapies were analyzed.Results: The 28-day all-cause mortality and in-hospital mortality rates were 52.87% and 67.82%, respectively, arising predominantly from intra-abdominal (56.32%) and respiratory tract infections (21.84%). A multivariate analysis showed that 28-day all-cause mortality was independently associated with the patient’s APACHE II score (p = 0.002) and presence of septic shock at BSI onset (p = 0.006). All-cause mortality was not significantly different between patients receiving tigecycline- or polymyxin B-based therapy (55.81% vs. 53.85%, p = 0.873), and between subgroups mortality rates were also similar. Conclusions: Critical illness indicators (APACHE II scores and presence of septic shock at BSI onset) were independent risk factors for 28-day all-cause mortality. There was no significant difference between tigecycline- and polymyxin B-based therapy outcomes. Prompt and appropriate infection control should be implemented to prevent CRKP infections.

Background: Patients with chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSAS) overlap syndrome (OS) are thought to be at increased risk for cardiovascular diseases.Objective: To evaluate the burden of cardiovascular diseases and long-term outcomes in patients with OS.Methods: This was a retrospective cohort study. The prevalence of cardiovascular diseases and 1-year mortality were compared among patients diagnosed with OS (OS group), COPD alone (COPD group) and OSAS alone (OSAS group), and Cox proportional hazards models were used to assess independent risk factors for all-cause mortality.Results: Overall, patients with OS were at higher risk for pulmonary hypertension (PH), heart failure and all-cause mortality than patients with COPD or OSAS (all p < 0.05). In multivariate Cox regression analysis, the Charlson comorbidity index (CCI) score [adjusted hazard ratio (aHR): 1.273 (1.050–1.543); p = 0.014], hypertension [aHR: 2.006 (1.005–4.004); p = 0.048], pulmonary thromboembolism (PTE) [aHR: 4.774 (1.335–17.079); p = 0.016] and heart failure [aHR: 3.067 (1.521–6.185); p = 0.002] were found to be independent risk factors for 1-year all-cause mortality.Conclusion: Patients with OS had an increased risk for cardiovascular diseases and 1-year mortality. More efforts are needed to identify the causal relationship between OS and cardiovascular diseases, promoting risk stratification and the management of these patients.

741 Background: We sought to investigate utility of pre-operative neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and De Ritis Ratio as predictors of all-cause mortality (ACM) and renal functional decline renal cell carcinoma (RCC). Methods: Multi-institutional retrospective analysis of patients undergoing surgery for RCC. Multivariable analysis (MVA) was conducted to elucidate independent risk factors for ACM, de novo estimated glomerular filtration rate (eGFR)<45 ml/min/1.73m2 and eGFR<30 ml/min/1.73m2. Kaplan-Meier analysis (KMA) was used to investigate ACM, and de novo CKD. Results: 2928 patients were analyzed [1850 Male/1078 Female, median follow up 30.5 months, median tumor size 4.5 cm, 1741 partial nephrectomy (PN)/1187 radical nephrectomy (RN)]. 690 patients had NLR ≥ 3, while 208 patients had NLR ≥ 6; 110 patients had PLR ≥ 3; and 474 patients had De Ritis Ratio ≥ 3. MVA for risk factors associated with worsened ACM showed male sex (OR 1.6, p=0.02), HTN (OR 2.1, p=0.001), increasing tumor size (OR 1.12, p<0.001), clear cell RCC (OR 2.0, p=0.001), RN (OR 1.6, p=0.048), NLR≥ 6 (OR=2.4, p=0.001), Di Ritis Ratio≥3 (OR 2.4, p<0.001), and de novo eGFR<45 (OR=1.6, p=0.015) to be independent risk factors. MVA for factors associated with development of eGFR<45 included increasing age (OR 1.03, p<0.001), male (OR 1.5, p=0.01), HTN (OR 2.3, p<0.001), clear cell RCC (OR 2.2, p<0.001), RN (OR 6.8, p=0.03), NLR≥6 (OR 2.0, p=0.002), and Di Ritis Ratio≥3 (OR 2.3, p<0.001) to be independently associated. Variables associated with development of eGFR<30 included age (OR 1.05, p<0.001), DM (OR=3.01, p<0.001), black race (OR 1.9, p=0.005), Di Ritis Ratio≥3 (OR 2.0, p=0.001), and NLR≥6 (OR 2.1, p=0.002). PLR was not associated with OS, de novo eGFR<45, or de novo eGFR<30. On KMA, NLR≥6 was associated with worse OS (p<0.001). Di Ritis ratio ≥1.5 was associated with worse OS p<0.001 and Di Ritis ratio (≥3) was associated decreased freedom from of de novo eGFR<45 (p=0.026). Conclusions: Elevated NLR and De Ritis Ratio were associated with functional decline and worsened OS, while PLR was not predictive. These markers may be helpful in identifying high-risk patients.

Abstract Background and Aims Vascular calcification is the risk factor for cardiovascular event, cardiovascular mortality and all-cause mortality in maintenance hemodialysis (MHD) patients. We investigated the effects of abdominal aortic calcification (AAC) progression on outcomes in MHD patients. Method 111 patients who were on MHD between Jun. 2014 and Oct. 2014 in the dialysis center and finished the AAC examination at baseline and two years later were included prospectively. We evaluated the progression of AAC by AAC score (AACs) at baseline and two years later. According to the change of AACs, the patients were divided into rapid AAC progression group (change of AACs&gt;median) and non-rapid AAC progression group (change of AACs≤median). We investigated the effects of AAC progression on outcomes in MHD patients in the follow-up period. Kaplan-Meier analysis was used to compare their survival rate. Uni- and multivariable Cox proportional hazard regression models were used to determine the risk factors of all-cause mortality, cardiovascular mortality and cardiovascular events. Results The presence of AAC was 78.4% (87/111), rapid AAC progression was seen in 54 patients, and non-rapid AAC progression was seen in 57 patients. The mean follow-up duration was 27.9(27.1, 28.0) months. Kaplan-Meier analysis showed that patients in rapid AAC progression group had a higher risk of mortality as compared to patients in non-rapid AAC progression group (P=0.017). Multivariate Cox regression analysis demonstrated that high baseline AACs (HR=1.135, 95%CI∼1.001∼1.286, P=0.048), hypoproteinemia (HR=0.789, 95%CI 0.640∼0.972, P=0.026) were independent risk factors for all-cause mortality. High baseline AACs (HR=1.187, 95%CI 1.038∼1.356, P=0.012), low spKt/V (HR=0.103, 95%CI 0.013∼0.801, P=0.030) were independent risk factors for cardiovascular mortality. Low spKt/V (HR=0.018, 95%CI 0.003∼0.115, P=0.000), hypoproteinemia (HR=0.736, 95%CI 0.608∼0.890, P=0.002) were independent risk factors for cardiovascular events. Conclusion Abdominal aortic calcification progression may increase the risk of cardiovascular events and death in MHD patients. Severity of abdominal aortic calcification, adequacy of dialysis, and nutritional status are predictors of outcomes in MHD patients.

Abstract Background: The prevalence of stroke recurrence, disability, and all-cause mortality of patients with minor ischemic stroke (MIS) remains problematic. The aim of the present study was to identify risk factors associated with adverse outcomes at 1 year after MIS in the Xi’an region of China. Methods: This prospective cohort study included MIS patients above 18 years old with National Institutes of Health Stroke Scale (NIHSS) score ≤ 3 who were treated in any of four hospitals in Xi’an region of China between January and December 2015. The 1-year prevalence of stroke recurrence, disability, and all-cause mortality were evaluated, respectively. Multivariate logistic regression analysis was performed to assess the association between the identified risk factors and clinical outcomes. Results: In this study, 131(10.5%,131/1252) patients were lost to follow-up at 1 year. A total of 1,121 patients included for analysis, the prevalence of stroke recurrence, disability, and all-cause mortality at 1 year after MIS were 3.4% (38/1121), 9.3% (104/1121), and 3.3% (37/1121), respectively. Multivariate logistic regression analysis identified age, current smoking, and pneumonia as independent risk factors for stroke recurrence. Age, pneumonia, and alkaline phosphatase were independent risk factors for all-cause mortality. Independent risk factors for disability were age, pneumonia, NIHSS score on admission, and leukocyte count. Conclusions: The 1-year outcomes of MIS in Xi’an region of China were not optimistic, especially with a high prevalence of disability. The present study indicated that age and pneumonia were the common independent risk factors affecting the 1-year outcomes of MIS in Xi’an region of China.

The aim of the present was to identify risk factors associated with adverse outcomes at 1-year after MIS in the Xi’an region of China. Methods: The cohort of this prospective cohort study included MIS patients aged 18–97 years with a National Institutes of Health Stroke Scale (NIHSS) score of ≤ 3 who were treated in any of four hospitals in Xi’an region of China between January and December 2015. The 1-year rates of stroke recurrence, disability, and all-cause mortality were evaluated. Multivariate logistic regression analysis was performed to assess the association between the identified risk factors and clinical outcomes. Results: Among the 1,121 patients included for analysis, the rates of stroke recurrence, disability, and all-cause mortality at 1 year after MIS were 3.4% (38/1121), 9.3% (104/1121), and 3.3% (37/1121), respectively. Multivariate logistic regression analysis identified age, current smoking, and pneumonia as independent risk factors for stroke recurrence. Age, pneumonia, and alkaline phosphatase were independent risk factors for all-cause mortality. Independent risk factors for disability were age, pneumonia, NIHSS score on admission, and leukocyte count. Conclusions: The 1-year outcomes of MIS is not optimistic in the Xi’an region of China. Early identification of risk factors for poor clinical outcomes, attention to high risk populations, and targeted interventions contribute to reducing the risk for poor clinical outcomes of patients at 1 year after onset of MIS.

The study aimed to investigate the risk factors of postpancreatectomy hemorrhage (PPH) after pancreaticoduodenectomy (PD). A retrospective analysis of 423 patients who underwent PD between January 2008 and January 2014 was conducted. The overall incidence and all-cause mortality of PPH were 9.9% (42/423) and 2.1% (9/423), respectively. Independent risk factors of early PPH were revascularization (odds ratio (OR) = 6.786; 95% confidence interval (95% CI): 1.785–25.792; P=0.005), history of abdominal surgery (OR = 5.009; 95% CI: 1.968–12.749; P=0.001), and preoperative albumin levels (OR = 4.863; 95% CI: 1.962–12.005; P=0.001). Independent risk factors of late PPH included postoperative pancreatic leakage (OR = 4.696; 95% CI: 1.605–13.740; P=0.005), postoperative biliary fistula (OR = 6.096; 95% CI: 1.575–23.598; P=0.009), postoperative abdominal infection (OR = 4.605; 95% CI: 1.108–19.144; P=0.036), revascularization (OR = 9.943; 95% CI: 1.900–52.042; P=0.007), history of abdominal surgery (OR = 8.790; 95% CI: 2.779–27.806; P<0.001), and preoperative albumin levels (OR = 5.563; 95% CI: 1.845–16.776; P=0.002).

Abstract Background Increased platelet reactivity (PR) is an established predictor of cardiovascular (CV) and all-cause mortality. However, therapeutic targeting of PR by tailored antiplatelet therapy (APT) failed to show significant clinical benefit. It remains unclear whether increased PR constitutes a risk-modifier that identifies patients that benefit from risk-factor adjustment. Purpose To identify risk factors that allow modification and/or elimination of increased CV and all-cause mortality in patients with altered PR. Methods ADP- and TRAP-induced PR was measured by CD62P and CD63 expression in 1780 patients who were referred for coronary angiography between 1997 and 2000 and participated in the LURIC study. Statistical analysis was performed by SPSS v25.0 and R v3.6.1 Results ADP-induced PR was an excellent predictor of CV-mortality and risk-equivalent to the presence of coronary artery disease (Figure 1A). Stratification of platelet ADP-response into tertiles demonstrated that patients with high-PR (HPR) and low-PR (LPR) were at increased risk for CV-mortality when compared to the reference group (HPR: HR 1.7 [95% CI: 1.3–2.3]; LPR: HR 1.4 [95% CI: 1.0–1.8]) (Figure 1B). Multivariable-adjustment did not change the association of PR with CV-mortality. Using a relative weight analysis, we identified HbA1c and estimated glomerular filtration rate (eGFR) as potential risk-modifiers. In addition, presence of APT appeared to be an exclusive risk-modifier in the HPR-group. In an multivariable-adjusted risk assessment, we verified that in the HPR group (i) treatment of PR by APT reduced CV-mortality with a HR of 0.5 (95% CI: 0.3–0.7) p=0.0004), (ii) HbA1c of &gt;7.0% in patients with diabetes increased CV-mortality with a HR of 2.0 (95% CI: 1.2–3.2 p=0.004) and (iii) eGFR &lt;60ml/min increased CV-mortality with a HR 1.7 (95% CI: 1.1–2.6 p=0.013). Other risk-factors including blood pressure (&lt;140mmHg), LDL-C (&lt;100mg/dL) and hs-CRP (&lt;2mg/dL) did not alter the mortality risk. None of the risk-modifiers tested affected CV-mortality risk of patients in the LPR group. In the HPR group, risk modification by APT and HbA1c &lt;7.0% in patients with diabetes independently reduced CV-mortality risk to a level that was no longer statistically different to the reference group (p&gt;0.05). Risk modification by an eGFR &gt;60ml/min led to a profound risk reduction in the HPR group but remained statistically different from the reference group (Figure 1C). Conclusion Here, we demonstrate that HPR and LPR are predictors for CV mortality in the LURIC study. Treatment of platelet hyperreactivity by APT, HbA1c of ≤7% in patients with diabetes and an eGFR ≥60ml/min were associated with a reduced CV-mortality in HPR patients and might constitute adjustable risk factors in this group. In addition, we were unable to identify any significant risk factors for patients with LPR underlining a high-risk patient group with insufficient therapeutic options.

The pharmacodynamic effect of clopidogrel varies among individuals; approximately a third will have high on-treatment platelet reactivity (HTPR) to adenosine diphosphate and may benefit from more intensive antiplatelet therapy. Platelet reactivity testing has an important role in monitoring the therapeutic efficiency of clopidogrel and the safety of more potent drugs that confer an increased bleeding risk, because it provides a direct measure of the biological effect of these drugs. Numerous studies have demonstrated an association between HTPR and the risk of cardiac events in acute coronary syndrome (ACS) or after percutaneous coronary intervention (PCI). While the prognostic value of platelet reactivity testing following PCI has been demonstrated repeatedly in cohort studies and meta-analyses, randomised controlled studies investigating the clinical utility of the technique to guide treatment decisions failed to improve clinical outcomes of clopidogrel-treated patients undergoing stent implantation. Available data suggest that platelet function monitoring may be carried out in clopidogrel-treated patients with a higher risk of thrombotic events. These include patient risk factors such as body mass index (BMI), type 2 diabetes, and those prior unexpected ischemic events such as stent thrombosis, as well as procedural risk factors. As we move towards conclusively defining a therapeutic window associated with both cardiovascular (upper threshold) and bleeding risk (lower threshold) for antiplatelet agents, platelet reactivity testing will become a central tool in the practice of personalised strategies.
