Predictor Of Long-term Prognosis Research Articles

Impact on clinical outcome of ventricular arrhythmias in patients undergoing transcatheter aortic valve implantation.

Transcatheter aortic valve implantation (TAVI) has become a largely used treatment for severe aortic stenosis. There are limited data, however, about predictors of long-term prognosis in this population. In this study, we assessed whether ventricular arrhythmias may predict clinical outcomes in patients undergoing TAVI. We performed a 24 h ECG Holter monitoring in 267 patients who underwent TAVI for severe aortic stenosis within 30 days from a successful procedure. The occurrence of frequent premature ventricular complexes (PVCs; ≥30/h), polymorphic PVCs and nonsustained ventricular tachycardia (NSVT) was obtained for each patient. Clinical outcome was obtained for 228 patients (85%), for an average follow-up of 3.5 years (range 1.0-8.6). Cardiovascular events (CVEs; cardiovascular death or resuscitated cardiac arrest) occurred in 26 patients (11.4%) and 63 patients died (27.6%). Frequent PVCs but not polymorphic PVCs and NSVT were found to be associated with CVEs at univariate analysis. Frequent PVCs were indeed found in 12 patients with (46.2%) and 35 without (17.3%) CVEs [hazard ratio 2.30; 95% confidence interval (CI) 1.03-5.09; P = 0.04], whereas polymorphic PVCs were found in 11 (42.3%) and 54 (26.7%) patients of the two groups, respectively (hazard ratio 1.44; 95% CI 0.64-3.25; P = 0.38), and NSVT in 9 (34.6%) and 43 patients of the two groups, respectively (hazard ratio 1.18; 95% CI 0.48-2.87; P = 0.72). Frequent PVCs, however, were not significantly associated with CVEs at multivariate Cox regression analysis (hazard ratio 1.53; 95% CI 0.37-6.30; P = 0.56). Both frequent PVCs, polymorphic PVCs and NSVT showed no significant association with mortality. In our study, the detection of frequent PVCs at Holter monitoring after TAVI was a predictor of CVEs (cardiovascular death/cardiac arrest), but this association was lost in multivariable analysis.

Impact on clinical outcome of ventricular arrhythmias in patients undergoing transcatheter aortic valve implantation (TAVI)

Abstract Background Transcatheter aortic valve implantation (TAVI) in the treatment of severe aortic stenosis has considerably grown in the latest years. There are limited data, however, about predictors of long-term prognosis in this population. Particularly, whether ventricular arrhythmic burden is associated with clinical outcome has poorly been investigated. Purpose The aim of our study was to investigate the association between ventricular arrhythmias and adverse clinical outcomes in patients undergoing TAVI. Methods We performed a 24-hour 3-channel ECG Holter monitoring (HM) in 267 consecutive patients who underwent TAVI for severe aortic stenosis at our Centre within 30 days from a successful procedure (average 10.2 days, range 2-30). For each patient we obtained the number of premature ventricular complexes (PVCs) and the presence of non-sustained ventricular tachycardia (NSVT, >3 PVCs with a rate >100 bpm). Frequent PVCs were defined as the presence of at least 30 PVCs per hour. We also collected clinical and echocardiographic findings for each patient. Assessment of clinical events at follow-up was performed by clinical visits or telephone interviews of patients or relatives (in case of fatal events). The primary endpoint of the study was the occurrence of cardiovascular events (CVE), a composite of cardiovascular death and resuscitation from cardiac arrest. All-cause-mortality was assessed as secondary endpoint. Survival Cox regression was applied to assess the univariate and multivariate association of clinical, echocardiographic and HM variables with endpoints. Results Clinical outcome could be obtained for 228 patients (85%), for an average follow-up of 3.5 years (range 1.0-8.6). Among these patients, frequent PVCs (≥30/hour) and episodes of NSVT at HM were found in 47 (20.6%) and 52 (22.4%) patients, respectively. CVE occurred in 26 patients (11.4%) and 63 patients died (27.6%). Frequent PVCs at HM were detected in 12 patients with (46.2%) and 35 patients without (17.3%) CVE (HR 2.29; 95% CI 1.03-5.09; p=0.04). One or more episodes of NSVT were detected in 9 patients with (34.6%) and 43 patients without (21.3%) CVE (HR 2.29; 95% CI 1.03-5.09; p=0.04), although it was not predictive of all-cause mortality (HR 1.18; 95% CI 0.48-2.77; p=0.52). Both the presence of PVCs>30/hour (HR 1.19; 95% CI 0.69-2.08; p=0.53) and NSVT (HR 0.93; 95% CI 0.52-1.65; p=0.22) were not significantly associated with all-cause mortality. Moreover, no clinical (age, gender, cardiovascular risk factors) and echocardiographic (aortic valve area, trans-aortic mean gradient, left ventricle mass and ejection fraction) variable showed significant association with both the primary and secondary outcome in our patients. Conclusions In our study the detection of frequent PVCs at HM after TAVI was a major predictor of CVE (cardiovascular death/cardiac arrest), suggesting that a 24-hour HM after TAVI can be helpful for risk stratification of these patients.

The Recovery of Left Ventricular Function in Cases of Primary Angioplasty for Acute Myocardial Infarction

Background: This study is to investigate the recovery in left ventricular ejection fraction in the first 3 months after acute myocardial infarction treated with primary angioplasty. Left ventricular function (LVF) is the main predictor of long term prognosis in cases of survival after acute myocardial infarction. Study aims to investigate successful improvement in left ventricular ejection fraction after primary angioplasty.
 Methodology: A cross sectional study was conducted at Chaudhary Pervaiz Ellahi Institute of Cardiology, Multan from 1stSeptember 2019 to 30thSeptember 2020. Left ventricular ejection fraction was evaluated in 100 patients treated with primary angioplasty. Primary angioplasty is a very 1st treatment to re-open the locked artery after acute myocardial infarction. Ejection fraction was measured with Echocardiography Simpson’s biplane method at 3rd day and 3 months after angioplasty. Collected data was analyzed by using SPSS version 23. Chi square test was applied to see association among variables.
 Results: One hundred patients were included this study. The mean age and BMI of the patients was 59.45±6.01 years and 24.76±8.02 kg/m2, respectively. Male 70 (70%) and female 30 (30%) ratio was 7:3. LVEF at 3rd month was observed in ≤40% in 223 (23.0%) patients and >40% in 77 (77%) patients. Male patients were greater in number that’s why LVEF is also observed in greater in male gender (p<0.001). Increase in age also have no impact on procedure success (p>0.050).
 Conclusion: Results of this study reveal that primary angioplasty is successful treatment plan in patients with acute myocardial infarction. A significant recovery of left ventricular function during 3 months after primary angioplasty in acute Myocardial infarction (MI) patients was observed.

Long-Term Outcomes of Stereotactic Radiosurgery for Postoperative World Health Organization Grade I Skull Base Meningioma: Utility of Ki-67 Labeling Index as a Prognostic Indicator.

Gross total resection, without causing neurological deficits, is challenging in skull base meningioma (SBM). Therefore, stereotactic radiosurgery (SRS) is an important approach for SBMs; however, it is difficult to predict the long-term prognosis. To identify the predictive factors for tumor progression after SRS for World Health Organization (WHO) grade I SBMs, focusing on the Ki-67 labeling index (LI). In this single-center retrospective study, factors affecting progression-free survival rates (PFSs) and neurological outcomes in patients undergoing SRS for postoperative SBMs were evaluated. Based on the Ki-67 LI, patients were classified into 3 groups: low (<4%), intermediate (4%-6%), and high LI (>6%). In the 112 patients enrolled, the cumulative 5- and 10-year PFSs were 93% and 83%, respectively. The PFSs were significantly higher in the low LI group (95% at 10 years) compared with the other groups (intermediate LI, 60% at 10 years, P = .007; high LI, 20% at 10 years, P = .001). Multivariable Cox proportional hazard analysis demonstrated that the Ki-67 LI was significantly associated with the PFSs (low vs intermediate LI; hazard ratio, 6.00; 95% CI, 1.41-25.54; P = .015; low vs high LI; hazard ratio, 31.90; 95% CI, 5.59-181.77; P = .001). Ki-67 LI may be a useful predictor of long-term prognosis in SRS for postoperative WHO grade I SBM. SRS provides excellent long- and mid-term PFSs in SBMs with Ki-67 LIs <4% or 4% to 6%, with a low risk of radiation-induced adverse events.

395 ASSESSMENT OF VENTRICULAR ARRHYTHMIAS IN PATIENTS UNDERGOING TRANCATHETER AORTIC VALVE IMPLANTATION (TAVI): IMPACT ON CLINICAL OUTCOME

Abstract Background Transcatheter aortic valve implantation (TAVI) in the treatment of severe aortic stenosis has considerably grown in the latest years. There are limited data, however, about predictors of long-term prognosis in this population. Particularly, whether arrhythmic burden is associated with clinical outcome has poorly been investigated. Methods We performed 24-hour 3-channel ECG Holter recording (HM) in 284 consecutive patients who underwent TAVI for severe aortic stenosis at our Center within 30 days from a successful procedure (average 10.2 days, range 2-30). For each patient we obtained the number of premature ventricular complexes (PVCs) and the presence of non-sustained ventricular tachycardia (NSVT, ≥3 PVCs with a rate ≥100 bpm). Assessment of clinical events at follow-up was performed by clinical visits or telephone interview of patients or relatives (in case of fatal events). The primary end-point of the study was a composite of cardiovascular death and resuscitation from cardiac arrest (CVE); total mortality was assessed as secondary end-point. Results Frequent PVCs (≥30/hour) and episodes of NSVT were found in 49 (20.2%) and 52 (21.4%) patients, respectively. Clinical outcome was obtained for 243 patients (85.6%). At an average follow-up of 3.5 year (range 1.0-8.6), CVE occurred in 25 patients (8.8%) and 64 died (22.5%). Frequent PVCs at HM were detected in 11/25 (44.0%) and 38/218 (17.4%) patients with and without CVE, respectively (p=0.006). Episodes of NSVT were detected in 9/25 (36.0%) and 43/218 (19.7%) patients with and without CVE, respectively (p=0.07). Furthermore, frequent PVCs were present in 18/64 (28.1%) and 31/179 (17.3%) patients dead and alive, respectively (p=0.07), whereas NSVT episodes were detected in 17/64 (26.6%) and 35/179 (19.6%) patients dead and alive, respectively (p=0.29). Frequent PVCs maintained independent association with CVE after correction for confounding variables at multivariable analysis (HR 2.63; 95 CI 1.05-6.62; p=0.04). Conclusions Our data indicate that assessment of ventricular arrhythmic burden after TAVI is helpful to identify patients at increased risk of cardiovascular death/cardiac arrest during medium follow-up.

Usefulness of Procalcitonin as a Predictor of Long-Term Prognosis in the Early Postoperative Period after Esophagectomy for Esophageal Cancer.

The aim of this study was to investigate the relationship between serum procalcitonin (PCT) levels after esophagectomy and infectious complications and long-term prognosis. A total of 105 patients who underwent esophagectomy between 2012 and 2019 were stratified into two groups: PCT-High group of ≥1 ng/mL and PCT-Low group of <1 ng/mL. The clinical outcomes and prognostic factors were compared between the two groups 2 postoperative days (POD), 4 POD, and 7 POD after esophagectomy. As the postoperative days passed, the association between PCT and infectious complications became stronger, and the positive predictive value was 100% at 7 POD. At 2 POD, there was no significant association between PCT elevation and infectious complications. Patients in the PCT-Low group had significantly worse overall survival (OS) and recurrence-free survival (RFS) than those in the PCT-High group at 2 POD (p = 0.026 and p = 0.011, respectively). In multivariate analysis, advanced pathological stage (hazard ratio (HR), 5.348; 95% confidence interval (CI), 2.299–12.500; p < 0.001) and PCT-Low group at 2 POD (HR, 3.673; 95% CI, 1.116–12.092; p = 0.032) were also independent predictors of worse OS. PCT in the early postoperative period after esophagectomy could be a good predictor of prognosis.

Predictors of long-term prognosis in rheumatoid arthritis-related interstitial lung disease.

The aim of the study was to identify specific clinical and serum protein biomarkers that are associated with longitudinal outcome of RA-associated interstitial lung disease (RA-ILD). 60 RA patients with clinical and serological profiles were assessed by HRCT and pulmonary function tests (PFTs) at baseline (Year 0) and 5 years post enrollment (Year 5). Progression versus non-progression was defined based on changes in Quantitative Modified HRCT scores and PFTs over time. Specific serum protein biomarkers were assessed in serum samples at baseline and Year 5 by Multiplex enzyme-linked immunosorbent assays (ELISAs). At Year 5, 32% of patients demonstrated progressive RA-ILD, 35% were stable, and 33% improved. Baseline age and rheumatoid factor (RF) were significantly different between RA-ILD outcomes of progression vs. no-progression (p < 0.05). Changes in levels of CXCL11/I-TAC and MMP13 over 5 years also distinguished pulmonary outcomes (p < 0.05). A final binary logistic regression model revealed that baseline age and changes in serum MMP13 as well as CXCL11/I-TAC were associated with RA-ILD progression at Year 5 (p < 0.01), with an AUC of 0.7772. Collectively, these analyses demonstrated that baseline clinical variables (age, RF) and shifts in levels of selected serum proteins (CXCL11/I-TAC, MMP13) were strongly linked to RA-ILD outcome over time.

Association of Modified Geriatric Nutrition Risk Index and Handgrip Strength With Survival in Cancer: A Multi-Centre Cohort Study.

BackgroundThis study aimed to explore the value of combining the modified geriatric nutrition risk index (mGNRI) and handgrip strength (HGS) in the prognosis assessment of cancer.MethodsThis multicenter, prospective cohort study, enrolled 5,607 cancer patients from 27 medical centers across 17 provinces in China between June 2012 and December 2019. The primary outcome was overall survival. Secondary outcomes included the Karnofsky Performance Scale (KPS) score, Patient-Generated Subjective Global Assessment (PG-SGA) score, cachexia, and admission 90-day outcome. A composite prognostic score (mGNRI-HGS score) was developed based on the mGNRI and HGS. The Kaplan–Meier method was used to draw the survival curve, and log-rank analysis was used to estimate the survival rate. The Cox proportional hazards model was used to investigate the associations of the mGNRI, HGS or mGNRI-HGS score with risk of mortality among the cancer patients, adjusted for potential confounders.ResultsA low mGNRI (HR = 0.99, 95%CI = 0.98–0.99, p < 0.001) and low HGS (HR = 0.99, 95%CI = 0.98–0.99, p = 0.001) were associated with an increased risk of mortality. A severe mGNRI-HGS score was independently associated with reduced survival. Compared with patients with normal scores, the risk of mortality among the patients with moderate and severe mGNRI-HGS scores was 28.8 and 13.3% higher, respectively. Even within the same pathological stage, it presented significant gradient prognostic stratification. Additionally, a low mGNRI-HGS score was also independently associated with a higher risk of low KPS (p < 0.001), high PGSGA (p < 0.001), cachexia (p < 0.001), and adverse admission 90-day outcome (p < 0.001).ConclusionsThe mGNRI and HGS may be useful predictors of long-term prognosis in cancer patients. The combination of the two methods provides effective prognostic stratification for cancer patients and could predict physical frailty, malnutrition, and cachexia.

Plaque characteristics and prognosis in patients with peripheral arterial disease by angioscopic analysis

BackgroundThe plaques with higher grade of yellow color by angioscopy are reported to be associated with vulnerability leading to adverse outcomes in coronary artery diseases. However, no studies have been performed for peripheral artery disease (PAD). We aimed to evaluate the relationship of angioscopic findings of peripheral arteries with the long-term prognosis. MethodsAngioscopy of iliac or femoropopliteal artery was performed before endovascular therapy in patients with PAD. The local plaque color and presence of thrombus were evaluated. Multivariable Cox regression models were used to estimate hazard ratio (HR) for all-cause mortality or major adverse cardiovascular event (MACE) related to the plaque colors as well as presence of thrombus. ResultsAmong 67 patients, 49.3% had intensive yellow plaques (group H) and the rest had light yellow to yellow ones (group L). Thrombus was detected in 74.6% of the patients and the presence was not different between the two groups. In Kaplan-Meier analysis during a median follow-up of 976 days and 757 days, group H showed increased mortality and MACE compared with group L (p <0.01 for both). Multivariable analysis demonstrated that the intensive yellow color of plaque was independently associated with mortality and MACE [HR: 11.48, 95% confidence interval (CI): 2.19–211.1 and HR: 3.81, 95% CI: 1.36–13.48, respectively] after adjusting for the presence of thrombus. ConclusionsThe yellow color intensity in local plaques by angioscopy may be a novel predictor of long-term prognosis in patients with PAD, regardless of the presence of thrombus.

Prognostic Nutritional Index as a Novel Predictor of Long-Term Prognosis in Patients with Coronary Artery Disease After Percutaneous Coronary Intervention.

BackgroundThe Prognostic Nutritional Index (PNI) has been reported to be correlated with long-term outcomes after gastrointestinal tumor surgery. However, to our knowledge, only a few studies have shown that the PNI is related to cardiovascular diseases. Therefore, we aimed to assess the association between the PNI and long-term outcomes in patients with coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI).MethodsThis was retrospective observational study. A total of 3561 patients with CAD after PCI were retrospectively enrolled in the CORFCHD-ZZ study from January 2013 to December 2017. The patients (3519) were divided into three groups according to PNI tertiles: the first tertile (PNI < 47.12, n = 1173), the second tertile (47.12 ≤ PNI < 51.50, n = 1185), and the third tertile (PNI ≥ 51.50, n = 1161). The mean follow-up time was 37.59 ± 22.24 months. The primary endpoint long-term mortality, including all-cause mortality (ACM) and cardiac mortality (CM).Secondary endpoints were major adverse cardiovascular events (MACEs) and major adverse cardiovascular and cerebrovascular events (MACCEs).ResultIn our study, the incidences of ACM in the first, second, and third tertiles were 3.8%, 1.8% and 1.4%, respectively (P < 0.001). The incidences of CM occurring in the first, second, and third tertiles were 1.7%, 3.1% and 2.1%, respectively (P < 0.001).There was statistically significant different in primary endpoints incidence. MACEs occurred in 139 patients (11.8%) in the first tertile, 121 patients(11.1%) in the second tertile and 123 patients(10.8%) in the third tertile(P = 0.691). MACCEs occurred in 183 patients (15.6%) in the first tertile, 174 patients(14.7%) in the second tertile and 160 patients(13.85%) in the third tertile(P = 0.463).There was no statistically significant different in secondary endpoints incidence. Kaplan–Meier analyses showed that elevated PNI was significantly related to long-term CM (log rank, P < 0.001) and long-term ACM (log-rank, P < 0.001). Cox regression analyses suggested that compared with the patients in the first tertile, the risk of ACM was decreased to 60.9% (HR = 0.609, 95% CI: 0.398–0.932, P = 0.029) in the second tertile and 40.3%(HR = 0.403, 95% CI: 0.279–0.766, P = 0.003) in the third tertile, while the risk of CM was decreased to 58.8%(HR = 0.588, 95% CI: 0.321–0.969, P = 0.038) in the second tertile and 46.6%(HR = 0.466, 95% CI: 0.250–0.870, P = 0.017) in the third tertile. Multivariate Cox regression analyses showed that the PNI was an independent predictor of long-term ACM and CM.ConclusionOur finding shown that PNI is an independent predictor in CAD patients after PCI，the higher the PNI, the less occurring adverse event. Therefore，PNI may be an new biomarker to predict long-term outcome of CAD patients after PCI.

Non-Invasive Myocardial Infarction Ischemic Area Estimation Through Four-Dimensional Ultrasound

Background/Objective: Following myocardial infarction, infarct size and cardiac function are significant predictors of long-term prognosis. Most echocardiography studies rely on two-dimensional analysis for estimation of left ventricular function and electrical activity analysis for estimation of infarct area. Other imaging modalities, such as cardiac magnetic resonance imaging, are limited by time, cost, availability, patient tolerance, and incompatible implantable devices. Using an experimental mouse model of myocardial infarction, we hypothesize that four-dimensional ultrasound offers a possible alternative for easy, quick, and reliable estimation of infarct size. &#x0D; Methods: A cohort of 10 mice underwent four-dimensional cardiac imaging at baseline using a small animal high frequency ultrasound. A thoracotomy was subsequently performed, and a suture placed to ligate the left coronary artery approximately midway down the left ventricle. Sequential four-dimensional ultrasound was performed at six time points over 28 days, following which the mice were euthanized. The hearts were then removed and sent for embedding and sectioning into seven uniform segments stained using both H&amp;E and Masson’ s Trichrome.&#x0D; Results: Thus far, we have segmented the imaging and collected end diastolic volume, peak systolic volume, stroke volume, ejection fraction, transmural thickness, and circumferential strain. Additionally, four-dimensional models of the left ventricles have been rendered. Histological embedding, sectioning, and staining is still in progress, and therefore validation against the gold standard is still in process.&#x0D; Conclusion and Impact: Treatment and monitoring of myocardial infarction patients is reliant upon accurate assessment of patient status and prognosis. This study provides initial evidence for the validity of four-dimensional ultrasound as a tool for estimation of myocardial infarction size, providing an alternative to current two-dimensional methods that are less accurate and a more accessible alternative to highly specialized and costly equipment. Improved and accessible imaging methods have the potential to enhance patient care, ultimately improving overall health outcomes.

The prognostic value of lymph node ratio in comparison to positive lymph node count in penile squamous cell carcinoma

PurposePenile cancer is a rare male neoplasm with a wide variation in its global incidence. In this study, the prognostic value of lymph node ratio (LNR) was compared to that of positive lymph node count (PLNC) in penile squamous cell carcinoma.MethodsA total of 249 patients with penile squamous cell carcinoma were enrolled from The Surveillance, Epidemiology, and End Results (SEER) database between 2010 and 2015. The X-tile program was used to calculate the optimal cut-off values of LNR and PLNC that discriminate survival. We used the χ2 or the Fisher exact probability test to assess the association between clinical-pathological characteristics and LNR or PLNC. Univariate and multivariate Cox regression analyses were performed to identify independent prognostic factors for survival. Spearman correlation analysis was used to determine the correlation between LNR and PLNC.ResultsWe found that patients with high LNR tended to have advanced N stage, the 7th AJCC stage, and higher pathological grade, while patients with high PLNC had advanced N stage and the 7th AJCC stage. Univariate Cox regression analysis revealed that the N stage, M stage, the 7th AJCC stage, lymph-vascular invasion, LNR, and PLNC were significantly associated with prognosis. Multivariate Cox regression analysis demonstrated that LNR rather than PLNC was an independent prognostic factor for cancer-specific survival. Subgroup analysis of node-positive patients showed that LNR was associated with CSS, while PLNC was not.ConclusionLNR was a better predictor for long-term prognosis than PLNC in patients with penile squamous cell carcinoma.

Usefulness of Diastolic Function Score as a Predictor of Long-Term Prognosis in Patients With Acute Myocardial Infarction.

Background: Left ventricular diastolic function (LVDF) evaluation using a combination of several echocardiographic parameters is an important predictor of adverse events in patients with acute myocardial infarction (AMI). To date, the clinical impact of each individual LVDF marker is well-known, but the clinical significance of the sum of the abnormal diastolic function markers and the long-term clinical outcome are not well-known. This study aimed to investigate the usefulness of LVDF score in predicting clinical outcomes of patients with AMI.Methods: LVDF scores were measured in a 2,030 patients with AMI who underwent successful percutaneous coronary intervention from 2012 to 2015. Four LVDF parameters (septal e′ ≥ 7 cm/s, septal E/e′ ≤ 15, TR velocity ≤ 2.8 m/s, and LAVI ≤ 34 ml/m2) were used for LVDF scoring. The presence of each abnormal LVDF parameter was scored as 1, and the total LVDF score ranged from 0 to 4. Mortality and hospitalization due to heart failure (HHF) in relation to LVDF score were evaluated. To compare the predictive ability of LVDF scores and left ventricular ejection fraction (LVEF) for mortality and HHF, receiver operating characteristic (ROC) curve and landmark analyses were performed.Results: Over the 3-year clinical follow-up, all-cause mortality occurred in 278 patients (13.7%), while 91 patients (4.5%) developed HHF. All-cause mortality and HHF significantly increased as LVDF scores increased (all-cause mortality–LVDF score 0: 2.3%, score 1: 8.8%, score 2: 16.7%, score 3: 31.8%, and score 4: 44.5%, p < 0.001; HHF–LVDF score 0: 0.6%, score 1: 1.8%, score 2: 6.3%, score 3: 10.3%, and score 4: 18.2%, p < 0.001). In multivariate analysis, a higher LVDF score was associated with significantly higher adjusted hazard ratios for all-cause mortality and HHF. In landmark analysis, LVDF score was a better predictor of long-term mortality than LVEF (area under the ROC curve: 0.739 vs. 0.640, p < 0.001).Conclusion: The present study demonstrated that LVDF score was a significant predictor of mortality and HHF in patients with AMI. LVDF scores are useful for risk stratification of patients with AMI; therefore, careful monitoring and management should be performed for patients with AMI with higher LVDF scores.

Predictors for Long-Term Prognosis after Acute Coronary Syndrome

Summary Cardiovascular diseases (CVD) are the leading cause of invalidity and death in developed countries. Among them, the main cause of death is coronary artery disease. In this retrospective study, 172 patients with acute coronary syndrome (STEMI, NSTEMI, UA) are included. They had been hospitalized on an emergency basis in the Cardiology Department, Invasive Sector of Prof. Dr. St. Kirkovich Hospital in Stara Zagora, and the Cardiology Hospital -Yambol between January 2009 and February 2010. We found a significant difference in the age at acute coronary syndrome (ACS) occurrence by sex: earlier manifestation was observed in men (p=0.018). The univariant regression analysis showed that elderly age (p=0.005, OR 1.024), glomerular filtration &lt;90 ml/h (p=0.006, OR 0.964), GRACE-score &gt; 140 pt (p&lt;0.001, OR 1.045), HF (Killip class ≥ II) (p=0.002, OR 15.6) and EF&lt;40% (p=0.003, OR 1) were factors for adverse prognosis in the first, fifth and ninth year. Only GRACE-score was an independent predictor of death obtained by multivariate regression analysis in the study (p=0.002, OR 1.052). The factors influencing long-term survival adversely after ACS are age, smoking, chronic kidney disease, previously experienced myocardial infarction, diabetes mellitus, three-vessel coronary disease, and decreased systolic function of the left ventricle, and GRACE &gt; 140 p.

Sex-Related Differences in Clinical Features, Neuroimaging, and Long-Term Prognosis After Transient Ischemic Attack.

Background and Purpose:Differences in sex in the incidence, presentation, and outcome of events after ischemic stroke have been studied in depth. In contrast, only limited data are available after transient ischemic attack (TIA). We aim to assess sex-related differences in the presentation, cause, neuroimaging features, and predictors of long-term prognosis in patients with TIA.Methods:We carried out a prospective cohort study of consecutive patients with TIA from January 2006 to June 2010. Nondefinitive TIA events were defined by the presence of isolated atypical symptoms. The risk of stroke recurrence (SR) and composite of major vascular events were stratified by sex after a median follow-up time of 6.5 (interquartile range, 5.0–9.6) years.Results:Among the 723 patients studied, 302 (41.8%) were female and 79 (10.9%) suffered a nondefinitive TIA event. Vascular territory diffusion-weighted imaging patterns (odds ratio, 1.61 [95% CI, 0.94–2.77]), and nondefinitive TIA events (odds ratio, 2.66 [95% CI, 1.55–4.59]) were associated with women, whereas active smoking (odds ratio, 0.30 [95% CI, 0.15–0.58]) and large artery atherosclerosis causes (odds ratio, 0.50 [95% CI, 0.29–0.83]) were related to men. The risk of SR was similar in both sexes (12.6% [95% CI, 8.9–16.3] for women versus 14.3% [95% CI, 11.0–17.6] for men). In contrast, the risk of major vascular events was significantly lower in women than in men (17.5% [95% CI, 13.2–21.8] versus 23.8% [95% CI, 19.7–27.9]). In both sexes, after adjusting for age, large artery atherosclerosis was associated with SR (hazard ratio, 3.22 [95% CI, 1.42–7.24] and hazard ratio, 2.00 [95% CI, 1.14–3.51]). In a Kaplan-Meier analysis, females with positive diffusion-weighted imaging (P=0.014) and definitive TIA (log-rank test P=0.022) had a significantly higher risk of SR.Conclusions:Despite similar risks of SR, there were sex-related differences in baseline characteristics, presenting symptoms, patterns of acute ischemic lesions, cause, and outcomes. These findings encourage further research into optimal preventive strategies that take into account these differences.

Lymph Node Ratio Rather Than Positive Lymph Node Counts Has Better Prognostic Value in Patients With Testicular Germ Cell Tumors.

Background:Testicular cancer represents the most common malignancy in young adult men. In the current study, we sought to analyze and compare the prognostic value of lymph node ratio (LNR) as well as positive lymph node counts (LNC) to understand its clinical significance in testicular germ cell tumors.Methods:We employed eligibility criteria to recruit a total of 931 patients, with testicular cancer, from 2010 to 2015 from The Surveillance, Epidemiology, and End Results (SEER) database. We then used the X-Tile program to calculate LNR and LNC cutoff values and discriminate survival. We then calculated the overall and cancer specific survival rates and analyzed the association between LNR/LNC and clinical pathological characteristics using the χ2 test. Finally, we assessed the relationships between clinical pathological factors and patient survival using univariate Cox proportional hazard analysis.Results:Univariate analysis revealed a significant association between prognosis with age (HR, 5.169; 95% CI, 1.758-15.200; P = 0.003), AJCC stage (III vs I: HR, 9.298; 95% CI, 2.691-32.131; P < 0.001), M stage (HR, 7.897; 95% CI, 3.417-18.251; P < 0.001) and LNR (HR, 3.009; 95% CI, 1.275-7.098; P = 0.012). On the other hand, LNC (HR, 1.743; 95% CI, 0.687-4.420; P = 0.242) was not significantly associated with prognosis. Analysis of the association between LNR/LNC and clinical pathological characteristics showed that high LNR patients tended to have significantly larger tumor sizes (χ2 = 7.877, P = 0.005), as well as advanced T (χ2 = 13.195, P = 0.004), N ( χ2 = 86.775, P < 0.001), M (χ2 = 19.948, P < 0.001) and 7th AJCC (χ2 = 103.074, P < 0.001) stages. In addition, high LNC patients were significantly associated with T (χ2 = 8.799, P = 0.032), N (χ2 = 74.390, P < 0.001) and 7th AJCC (χ2 = 111.759, P < 0.001) stages.Conclusion:LNR was a better predictor for long-term prognosis and was closely associated with clinical pathological characteristics than LNC in patients with testicular germ cell tumors.

Specific pathogens as predictors of poor long-term prognosis after hospital discharge for community-acquired pneumonia

BackgroundSome studies have reported that long-term prognosis after pneumonia is poor. Our aim was to determine predictors of long-term outcomes with special attention to community-acquired pneumonia (CAP) etiology. MethodsWe studied 1930 patients who were hospitalized with CAP from January 2002 through November 2017 at Saitama Cardiovascular and Respiratory Center and were discharged alive. We conducted a retrospective study for calculation of survival rate using the Kaplan-Meier method and analysis of prognostic factors by multivariate analysis using a Cox proportional hazard model. ResultsThe median follow-up period was 442.5 (range 1–5514) days. During this period, 321 patients died. Median survival time was 11.9 years, and 1-year and 5-year survival rates were 93.8% and 74.0%, respectively. Among the patients’ demographics factors, old age, poor performance status (PS) score, pneumococcal vaccination history, some underlying respiratory diseases, and chronic heart failure were significant independent factors of poor prognosis. Among pathogens, Streptococcus pneumoniae (hazard ratio [HR]: 1.35, 95% confidence interval [CI]: 1.03, 3.07, P = 0.038) and Pseudomonas aeruginosa (HR: 1.68, 95% CI: 1.07, 2.64, P = 0.024) were significant independent factors of poor prognosis, whereas influenza virus tended to predict a good prognosis (HR: 0.60, 95% CI: 0.36, 1.02, P = 0.058). Respiratory disease accounted for 59% of all causes of death after CAP, and the rate of death from pneumonia was the largest at 22%. ConclusionNot only age, general condition, and comorbidities but also specific pathogens were predictors of long-term prognosis after hospital discharge for CAP.

Charlson comorbidity index and a composite of poor outcomes in COVID-19 patients: A systematic review and meta-analysis

Background and aimsThe ongoing COVID-19 pandemic is disproportionately affecting patients with comorbidities. Therefore, thorough comorbidities assessment can help establish risk stratification of patients with COVID-19, upon hospital admission. Charlson Comorbidity Index (CCI) is a validated, simple, and readily applicable method of estimating the risk of death from comorbid disease and has been widely used as a predictor of long-term prognosis and survival. MethodsWe performed a systematic review and meta-analysis of CCI score and a composite of poor outcomes through several databases. ResultsCompared to a CCI score of 0, a CCI score of 1–2 and CCI score of ≥3 was prognostically associated with mortality and associated with a composite of poor outcomes. Per point increase of CCI score also increased mortality risk by 16%. Moreover, a higher mean CCI score also significantly associated with mortality and disease severity. ConclusionCCI score should be utilized for risk stratifications of hospitalized COVID-19 patients.

S1121 Role of Markers of Heavy Metal Metabolism in Identification of Hepatic Fibrosis in Patients With Non-Alcoholic Fatty Liver Disease (NAFLD)

INTRODUCTION: Fibrosis & nonalcoholic steatohepatitis (NASH) are important predictors of long term prognosis in patients with non-alcoholic fatty liver disease (NAFLD). Oxidative stress (OS) has been shown to play a central role in progression of NAFLD, & changes in proteins associated with metal homeostasis may exacerbate OS. We investigated relationship of proteins related to transition metal metabolism with fibrosis in NAFLD. METHODS: Adult patients (>18y) who underwent liver biopsy for clinically suspected NAFLD at our institution were included. We retrospectively collected serum levels of ceruloplasmin (Cp), ferritin, iron, & transferrin saturation (Tsat) within 3 months of liver biopsy & calculated Cp/Tsat ratio (CT ratio) & Cp/Ferritin ratio (CF ratio). Histologic features were scored by an experienced pathologist using Non-alcoholic Steatohepatitis Clinical Research Network criteria. Fibrosis was staged as (0 - 4). Independent T test were used to compare the means & receiver operating characteristics (ROC) curves were plotted for assessing area under curve (AUC), sensitivity (Sn) & specificity (Sp). RESULTS: 174 patients were included in final analysis. The mean age of subjects was 48 y. Baseline features are depicted in Table 1. Biopsy proven NASH was seen in 61.5% of liver biopsies. No fibrosis was seen in 29.3% of liver biopsies & Stage 1, 2,3& 4 fibrosis were seen in 29.9%, 10.9%, 14.3% & 15.55% of samples. Mean Tsat was significantly higher (24.41% v/s 38.27%, P < 0.0001) & Cp (mg/dl) (27.82 v/s 24.91, P = 0.03) significantly lower between patients with advanced fibrosis (AF) (3-4) v/s early fibrosis (EF) (0-2). The mean CT ratio was also higher in patients with EF v/s AF (1.54 v/s 1.02, P = 0.01). The mean Tsat of patients with fibrosis v/s without fibrosis was higher (31.4% v/s 21.57% P < 0.005) however mean Cp (mg/dl) values were not significantly different (27.88 v/s 27.58, P = 0.42). The ROC curves show CF ratio (Figure 1) at a cut off of 0.10 had AUC = 0.61 (Sn = 70%, Sp = 52% P = 0.01) to detect any fibrosis & CT ratio (Figure 2) at a cut off 0.86 had AUC = 0.65 (Sn = 69%, Sp = 50% P = 0.002) for differentiating EF v/s AF. CONCLUSION: Our data reveals changes in ceruloplasmin: transferrin system, which decreases the content of toxic ions of Fe2+ in NAFLD. Tsat, Cp, CF ratio & CT ratio are useful non-invasive biomarkers in identifying NAFLD patients with fibrosis. Markers of heavy metal metabolism can spare patients from liver biopsies & can be potential therapeutic targets in future.Table 1.: Demographic and histological features of study populationFigure 1.: ROC curve for fibrosis stage determination (0 vs 1-4) based on CF RATIO.Figure 2.: ROC curve for fibrosis stage determination (0-2 vs 3-4) based on CT Ratio.

Predictive Effectiveness of the Glasgow Prognostic Score for Gastrointestinal Stromal Tumors

The aim of this study was to evaluate the significance of the Glasgow prognostic score (GPS) in patients with resected gastrointestinal stromal tumors (GISTs). Forty-six GIST patients who underwent radical resection between January 2004 and December 2011 were enrolled in this retrospective study. The clinicopathological parameters examined included predictors of recurrence-free survival (RFS). Univariate and multivariate analysis of prognostic factors related to RFS were calculated using Cox proportional hazards model. The GPS classification system revealed 37 (80.4%), 6 (13.1%), and 3 (6.5%) patients with a GPS of 0, 1, and 2, respectively. Patients with GPS 1/2 had a significantly shorter RFS compared to those with GPS 0 (P = 0.01). The 3- and 5-year RFS rates for patients with GPS 0 were 94.0% and 90.9%, respectively, compared to 66.7% and 53.3%, respectively, for patients with GPS 1/2. Univariate analyses indicated that tumor size (P < 0.01), mitotic rate (P < 0.01), higher GPS (P < 0.01), and platelet count (P = 0.04) were prognostic factors for RFS; tumor size (P = 0.01) and GPS (P = 0.04) were independent prognostic factors in multivariate analysis. Preoperative high GPS were predictors of long-term prognosis in patients with resected GISTs.
