Objectives: To investigate whether serum fibroblast growth factor 21 (FGF21) levels can be used to predict the future development of major adverse cardiovascular events (MACEs). Methods: This study included 253 patients who received subsequent follow-up, and complete data were collected for 234 patients. Independent predictors of MACEs were identified by using the Cox proportional-hazards regression analysis. The prognostic value of FGF21 levels for MACEs was evaluated by Kaplan-Meier survival analysis. Results: Of 229 patients finally enrolled in the analysis, 27/60 without coronary artery disease (CAD) at baseline experienced a MACE, and 132/169 patients with CAD at baseline experienced a MACE. Among patients with CAD at baseline, serum FGF21 levels were significantly higher in patients with MACEs (p < 0.05) than in patients without MACEs. Kaplan-Meier survival analysis showed patients with a higher serum FGF21 had a significantly lower event-free survival (p = 0.001) than those with a lower level. Further Cox proportional-hazards regression analysis, including the traditional risk factors for cardiovascular disease, showed that serum FGF21 was an independent predictor of MACE occurrence. Conclusions: In patients with CAD at baseline, an elevated serum FGF21 level was associated with the development of a MACE in the future.

Background: Measuring glycosylated hemoglobin (HbA1c) is a simple way to assess patients with prediabetes ordiabetes mellitus. It has been shown that HbA1c level predicts prognosis in patients with coronary artery disease (CAD)and the incidence of diabetes mellitus. However, the prognostic significance of HbA1c level in Asian patients withprediabetes and CAD is not yet clear. Our study aimed to determine the relationship between HbA1c level and majoradverse cardiovascular events (MACE) in patients with prediabetes and CAD.Methods: We enrolled 1367 patients with prediabetes and CAD in the final analysis, and grouped them according tothe HbA1c level. Primary end points included nonfatal myocardial infarction, hospitalization for unstable angina, andischemia-driven revascularization. Cox proportional-hazards regression analysis was used to determine the relationshipbetween HbA1c level and MACE after our accounting for confounding factors.Results: A total of 1367 patients (age 58.8 ± 10.3 years; 71.6% men) were included. During 43 months of follow-up,197 patients experienced at least one primary end point event. Multivariate Cox proportional-hazards regression analysisshowed in comparison of HbA1c levels that the hazard ratio for primary end points was 4.110, with a 95% confidence interval of 2.097–6.011 (P < 0.001).Conclusions: HbA1c level positively correlated with MACE, demonstrating it is a valuable indicator for independentlypredicting MACE in Asian patients with prediabetes and CAD.

Abstract Background Stable coronary artery disease (CAD) patients with myocardial damage have a poor prognosis compared to those without myocardial damage. Recently, malnutrition has been reported to affect the prognosis of cardiovascular diseases. However, the effects of malnutrition on prognosis of CAD patients with myocardial damage remains uncertain. We investigated the effects of malnutrition on prognosis of CAD patients with myocardial damage who received percutaneous coronary intervention (PCI). Methods Subjects comprised 241 stable CAD patients with myocardial damage due to myocardial ischemia or infraction. Patients underwent successful revascularization for the culprit lesion by PCI using second-generation drug-eluting stents and intravascular ultrasound. The geriatric nutritional risk index (GNRI), which is widely used as a simple method for screening nutritional status using body mass index and serum albumin, was used to assess nutritional status. Associations between major cardiovascular and cerebrovascular events (MACCE) and patient characteristics were assessed. Results Mean GNRI was 100 ± 13, and there were 55 malnourished patients (23%; GNRI < 92) and 186 non-malnourished patients (77%). MACCE occurred within 3 years after PCI in 42 cases (17%), including 34 deaths (14%), and the malnourished group showed a higher rate of MACCE (38%) compared with the non-malnourished group (11%, p < 0.001). Univariate Cox proportional hazards analyses showed that MACCE was associated with age [hazard ratio (HR), 1.04; 95% confidence interval (CI), 1.04–1.07; p = 0.004], prior heart failure (HR 2.35; 95% CI 1.10–5.01; p = 0.027), high-sensitivity C-reactive protein (HR 1.08; 95% CI 1.03–1.11; p < 0.001), hemodialysis (HR 2.63; 95% CI 1.51–4.58; p < 0.001) and malnutrition (HR 3.69; 95% CI 2.11–6.42; p < 0.001). Multivariate Cox proportional hazards analysis revealed hemodialysis (HR 2.17; 95% CI 1.19–3.93; p = 0.011) and malnutrition (HR 2.30; 95% CI 1.13–4.67; p = 0.020) as significantly associated with MACCE. Furthermore, Cox proportional hazards models using malnutrition and hemodialysis revealed that patients with malnutrition and hemodialysis were at greater risk of MACCE after PCI than patients with neither malnutrition nor hemodialysis (HR 6.91; 95% CI 3.29–14.54; p < 0.001). Conclusions In CAD patients with myocardial damage, malnutrition (GNRI < 92) represents an independent risk factor for MACCE. Assessment of nutritional status may help stratify the risk of cardiovascular events and encourage improvements in nutritional status.

Introduction: The atherogenicity of residual cholesterol (RC) has been underlined by recent guidelines, which was linked to coronary artery disease (CAD), especially for patients with diabetes mellitus (DM). Hypothesis: This study aimed to examine the prognostic value of plasma RC, clinically presented as triglyceride-rich lipoprotein-cholesterol (TRL-C) or remnant-like lipoprotein particles-cholesterol (RLP-C), in CAD patients with different glucose metabolism status. Methods: Fasting plasma TRL-C and RLP-C levels were directly calculated or measured in 4331 patients with CAD. Patients were followed for incident MACEs for up to 8.6 years and categorized according to both glucose metabolism status [DM, pre-DM, normal glycaemia regulation (NGR)] and RC levels. Cox proportional hazards model was used to calculate hazard ratios (HRs) with 95% confidence intervals. Results: During a mean follow-up of 5.1 years, 541 (12.5%) MACEs occurred. The risk for MACEs was significantly higher in patients with elevated RC levels after adjustment for potential confounders. No significant difference in MACEs was observed between pre-DM and NGR groups (p>0.05). When stratified by status of glucose metabolism and RC levels, highest levels of RLP-C, calculated and measured TRL-C were significant and independent predictors of developing MACEs in pre-DM (HR: 2.10, 1.98, 1.92, respectively; all p<0.05) and DM (HR: 2.25, 2.00, 2.16, respectively; all p<0.05). Conclusions: In this large cohort study with long-term follow-up, data firstly demonstrated that higher RC levels were significantly associated with the worse prognosis in DM and pre-DM patients with CAD, suggesting RC might be a target for patients with impaired glucose metabolism.

Background: Little is known about the association between coronary artery disease (CAD) and the risk of heart failure (HF) after myocardial infarction (MI), and whether it differs by reduced (HFrEF) or preserved (HFpEF) ejection fraction (EF) has yet to be determined. Subjects and Methods: Olmsted County, Minnesota residents (n=1,924; mean age, 64 years; 66% male) with first MI diagnosed in 1990-2010 and no prior HF were followed through 2013. Framingham Heart Study criteria were used to define HF, which was further classified according to EF (applying a 50% cutoff). The extent of angiographic CAD was defined at index MI according to the number of major epicardial coronary arteries with ≥50% lumen diameter obstruction. Fine & Gray and Cox proportional hazards regression models were used to assess the association of CAD categories with incidence of HF, and multiple imputation methodology was applied to account for the 19% with missing EF data. Results: During a mean (SD) follow-up of 6.7 (5.9) years, 594 patients developed HF. Adjusted for age and sex, with death considered a competing risk, the cumulative incidence rates of HF among patients with 1- (n=581), 2- (n=622), and 3-vessel disease (n=721) were 11.2%, 14.6% and 20.5% at 30 days; and 18.1%, 22.3% and 29.4% at 5 years after MI, respectively. The increased risk of HF with greater number of occluded vessels was only modestly attenuated after further adjustment for patient and MI characteristics, and did not differ materially by EF (Table). Conclusions: The extent of angiographic CAD expressed by the number of diseased vessels is independently associated with HF incidence after MI. The association is evident promptly after MI and applies to both HFrEF and HFpEF.

Abstract Background In patients undergo PCI for coronary artery disease, target lesion calcification is associated with major cardiac events. Malnutrition is the important factor to cause frailty and sarcopenia which affect prognosis of cardiovascular diseases. However, the relationship between morphology in target lesions and malnutrition in patients undergo PCI is still uncertain. Purpose The aim of the present study was to investigate how malnutrition affects prognosis of stable angina patients underwent PCI and morphology in target lesions. Methods The subject was 206 consecutive stable angina patients undergone successful PCI using second-generation drug eluting stents and intravascular ultrasound (IVUS). The study patients were divided into two groups based on malnutrition or non-malnutrition. Nutritional status was assessed by Geriatric Nutritional Risk Index (GNRI), and patients with GNRI&lt;92 at admission were defined as malnutrition group (MG). We investigated the association between malnutrition on admission and outcome, and morphology in target lesions assessed by IVUS. Target lesion morphology were divided into moderate/severe calcified group and none/mild calcified group. Results All-cause death and MACCE (major cardiovascular and cerebrovascular events) ≤3 years after PCI were 15 cases (7%) and 33 cases (16%). MG had higher rate of all-cause death (20 vs. 6%, p=0.001) and MACCE (37 vs. 10%, p&lt;0.001) than those of non-MG. Kaplan Meier analysis elucidated that survival rate was significantly lower in MG compared to that in non-MG (p&lt;0.001). As a result of cox proportional hazards analysis, all-cause death was associated with age [hazard ratio (HR): 1.05, 95% confidence interval (CI): 1.01–1.10, p=0.006)], hs-CRP (HR: 1.03, 95% CI: 1.03–1.12, p&lt;0.001), hemodialysis (HR: 2.25, 95% CI: 1.08–4.68, p=0.029), left ventricular ejection fraction (LVEF) (HR: 0.97, 95% CI: 0.95–0.99, p=0.017) and malnutrition (HR: 4.38, 95% CI: 2.11–9.09, p&lt;0.001) in the univariate analysis. Similarly, cox proportional hazards analysis revealed that age (HR: 1.04, 95% CI: 1.01–1.07, p=0.018), hs-CRP (HR: 1.08, 95% CI: 1.03–1.11, p&lt;0.001), hemodialysis (HR: 2.68, 95% CI: 1.45–4.94, p=0.002), LVEF (HR: 0.97, 95% CI: 0.95–0.99, p=0.002) and malnutrition (HR: 4.14, 95% CI: 2.23–7.67, p&lt;0.001) were significantly associated with MACCE. Multivariate analysis for all-cause death and MACCE revealed that malnutrition was an independent risk factor (HR: 3.47, 95% CI: 1.52–7.94, p=0.003, HR: 3.76, 95% CI: 1.87–7.58, p&lt;0.001). Furthermore, MG was significantly associated with moderate/severe target calcified lesions assessed by IVUS compared to those of patients in non-MG (67 vs. 27%, p&lt;0.001) regardless with or without hemodialysis. Conclusions Malnutrition was a crucial independent risk factor for stable angina patients who underwent PCI and was significantly associated with moderate/severe target calcified lesions.

ABSTRACTTo assess the risk of acute kidney injury (AKI) attributable to aminoglycosides (AGs) in patients with severe sepsis or septic shock, we performed a retrospective cohort study in one medical intensive care unit (ICU) in France. Patients admitted for severe sepsis/septic shock between November 2008 and January 2010 were eligible. A propensity score for AG administration was built using day 1 demographic and clinical characteristics. Patients still on the ICU on day 3 were included. Patients with renal failure before day 3 or endocarditis were excluded. The time window for assessment of renal risk was day 3 to day 15, defined according to the RIFLE (risk, injury, failure, loss, and end-stage renal disease) classification. The AKI risk was assessed by means of a propensity-adjusted Cox proportional hazards regression analysis. Of 317 consecutive patients, 198 received AGs. The SAPS II (simplified acute physiology score II) score and nosocomial origin of infection favored the use of AGs, whereas a preexisting renal insufficiency and the neurological site of infection decreased the propensity for AG treatment. One hundred three patients with renal failure before day 3 were excluded. AGs were given once daily over 2.6 ± 1.1 days. AKI occurred in 16.3% of patients in a median time of 6 (interquartile range, 5 to 10) days. After adjustment to the clinical course and exposure to other nephrotoxic agents between day 1 and day 3, a propensity-adjusted Cox proportional hazards regression analysis showed no increased risk of AKI in patients receiving AGs (adjusted relative risk = 0.75 [0.32 to 1.76]). In conclusion, in critically septic patients presenting without early renal failure, aminoglycoside therapy for less than 3 days was not associated with an increased risk of AKI.

e17553 Background: Phosphorylation of the H2AX histone is an early indicator of DNA double-strand breaks and of the resulting DNA damage response. In the present study we assessed the expression of γ-Η2ΑΧ in a cohort of 96 patients with non-small cell lung carcinoma and evaluated its role as a prognostic indicator in resectable NCSLC patients. Methods: 96 parafin-embedded specimens of non-small lung cancer patients were examined. All patients underwent radical thoracic surgery of primary tumor (lobectomy or pneumonectomy) and regional lymph nodes dissection. γ-Η2ΑΧ expression was assessed by standard immunohistochemistry.Multivariate Cox proportional hazards regression analysis, using a backward selection approach, were performed to explore the independent effect of variables on survival. All tests were two tailed and statistical significance was considered for p values <0.05. Results: Follow-up was available for all patients; mean duration of follow-up was 27.50 ± 14.07 months (range 0.2-57 months, median 24 months). Sixty-three patients (65.2%) died during the follow-up period. The mean survival time was 32.2 ± 1.9 months (95% CI = 28.5 to 35.8 months; median 30.0 months); one, two and three-year survival rates were 86.5 ± 3.5%, 57.3 ± 5.1% and 37.1 ± 5.4% respectively. Low γ-H2AX expression was associated with a significant better survival as compared with those having high γ-H2AX expression (23.2 months for high γ-Η2ΑΧ expressin vs 35.3 months for low γ-H2AX expression, p=0.009; HR=1.95, 95% CI=1.15-3.30). Further investigation with multivariate Cox proportional hazards regression analysis revealed that high expression of γ-H2AX remained independent prognostic factors of worse overall survival (HR=2.15, 95% CI=1.22-3.79, p=0.026). Conclusions: Our study is the first study to demonstrate that overexpression of γ-Η2ΑΧ is an independent prognostic indicator of worse overall survival in patients with non-small lung cancer. Further studies are needed to confirm our results.

Objectives. To evaluate whether serum interleukin-6 (IL-6) is associated with increased risk of mortality in coronary artery disease (CAD) patients.Methods. We performed a prospective cohort study of 718 CAD patients from the Guangzhou Cardiovascular Disease Cohort (GCDC) study. Multivariable-adjusted Cox proportional hazards regression analyses were used to examine the association between serum IL-6 with all-cause and cardiovascular mortality.Results. During the 1663 person-years of followup, the cumulative all-cause mortality and cardiovascular mortality were 6.5% (n=47) and 3.3% (n=24), respectively. The mean length of followup was2.32±0.81years. In the multivariable analyses, a one-SD increment in log-transformed serum IL-6 was positively associated with an increased risk of all-cause and cardiovascular mortality, with hazard ratios (HR) of 2.93 (95% CI, 2.11–4.08) and 2.04 (95% CI, 1.34–3.68) within the patients combined and 2.98 (95% CI, 2.12–4.18) and 3.10 (95% CI, 1.98–4.85) within males, respectively. Patients in the highest serum IL-6 tertile versus the lowest tertile were at higher risk of all-cause and cardiovascular mortality, with HR of 17.12 (95% CI 3.11–71.76) and 8.68 (95% CI, 1.88–37.51), respectively.Conclusions. In hospitalized patients with CAD, serum IL-6 is significantly associated with all-cause and cardiovascular mortality.

Crowns and large amalgams protect structurally compromised teeth to various degrees in different situations. The aim of this investigation was to evaluate the survival of teeth with these two types of restorations and the factors associated with better outcomes. Retrospective administrative and chart data were used. Survival was defined and modeled as: (1) receipt of no treatment and (2) receipt of no catastrophic treatment over five- and 10-year periods. Analyses included: Kaplan-Meier survival curves, Log-Rank tests, and Cox proportional hazards regression modeling. Crowns survived longer with no treatment and with no catastrophic treatment; however, mandibular large amalgams were least likely to have survived with no treatment, and maxillary large amalgams were least likely to have survived with no catastrophic treatment. Having no adjacent teeth also decreased survival. Crowns survived longer than large amalgams, but factors such as arch type and the presence of adjacent teeth contributed to the survival of large amalgams.

Abstract PurposeT-cadherin is an immunoglobulin-like adhesion molecule which acts as a tumor suppressor gene, programmed cell death ligand 1 (PD-L1) is a cell surface protein that involves in the suppression of the immune system. This study aimed at exploring the correlation between T-cadherin and PD-L1, as well as their prognostic value in patients with HPV-negative head and neck squamous cell carcinoma (HNSCC). MethodsIn this study, immunohistochemical staining was used to determine the protein expression of T-cadherin and PD-L1 in 104 tissue specimens of HPV-negative HNSCC. Spearman linear correlation analysis was used to determine the association between protein expression of T-cadherin and PD-L1. Kaplan-Meier analysis was used to plot overall survival (OS) and disease-free survival (DFS) curves. Cox proportional hazards regression analysis was used to conduct univariate and multivariate analysis. ResultsThe results showed a large negative association between protein expression of T-cadherin and PD-L1 (r=-0.775, P<0.01), expression of T-cadherin and PD-L1 were associated with OS (P=0.021 and 0.034, respectively) and DFS (P=0.012 and 0.016, respectively) in patients with HPV-negative HNSCC. Cox proportional hazards regression analysis revealed that expression of T-cadherin and PD-L1 were independent prognostic predictors for OS and DFS in patients with HPV-negative HNSCC. The worst prognosis was observed in patients with T-cadherin negative/PD-L1 positive.ConclusionIn conclusion, expression of T-cadherin and PD-L1 were inversely correlated and were independent prognostic factors for patients with HPV-negative HNSCC.
