Object: Patients with aneurysmal subarachnoid hemorrhage (aSAH) have an increased incidence of cardiac events and short-term unfavorable neurological outcomes during the acute phase of bleeding. We studied whether troponin I elevation after ictus can predict future major adverse cardiac events (MACEs) and long-term neurological outcomes after 2 years.Methods: Consecutive aSAH patients within 3 days of bleeding were eligible for review from a prospective observational cohort (ClinicalTrials.gov Identifier: NCT04785976). Potential predictors of future MACEs and unfavorable long-term neurological outcomes were calculated by Cox and logistic regression analyses. Additional Kaplan–Meier curves were performed.Results: A total of 213 patients were enrolled with an average follow-up duration of 34.3 months. Individuals were divided into two groups: elevated cTnI group and unelevated cTnI group. By the last available follow-up, 20 patients had died, with an overall all-cause mortality rate of 9.4% and an annual all-cause mortality rate of 3.8%. Patients with elevated cTnI had a significantly higher risk of future MACEs (10.6 vs. 2.1%, p = 0.024, and 95% CI: 1.256–23.875) and unfavorable neurological outcomes at discharge, 3-month, 1-, 2-years, and last follow-up (p = 0.001, p < 0.001, p = 0.001, p < 0.001, and p < 0.001, respectively). In the Cox analysis for future MACE, elevated cTnI was the only independent predictor (HR = 5.980; 95% CI: 1.428–25.407, and p = 0.014). In the multivariable logistic analysis for unfavorable neurological outcomes, peak cTnI was significant (OR = 2.951; 95% CI: 1.376–6.323; p = 0.005). Kaplan–Meier analysis indicated that the elevated cTnI was correlated with future MACE (log-rank test, p = 0.007) and subsequent death (log-rank test, p = 0.004).Conclusion: cTnI elevation after aSAH could predict future MACEs and unfavorable neurological outcomes.

Long Term Impact

9528 Background: IREs are associated with immunotherapy (IT) for cancer and while reports suggest improvement in TC and OS with induced IREs, the long-term impact is unclear. IL2 has been the major IT for patients (pts) with renal cell carcinoma (RCC) and melanoma (MM) since 1992. We evaluated IREs reports in the PROCLAIMSM data base (2008-2016) of IL2-treated pts. Methods: Reports on 614 (MM) and 843 (RCC) pts were queried for IREs. IREs were categorized as occurring before, during, or after IL-2 and related to any checkpoint inhibitor (CPI). TC (CR+PR+SD) was compared between no IRE and IRE, using Fisher’s exact test. OS curves were estimated by Kaplan-Meier method, and comparison of no IRE/before IL2 with during/after IL2, was analyzed by log-rank test. Results: With a median (med) follow-up of 3.5+ years (range 1-8+ year), 140 IREs were reported in 118 pts (9.6% of all PROCLAIMSM pts): 93 (15%) in MM; 47 (5.6%) in RCC. 25 IREs were prior to IL2; 13 IREs were during IL2; 102 were after IL2. Of the latter 102, 31 were after IL2 and after subsequent CPI; 71 were attributed to IL2 only; and in 13, IREs were due to either IL2 or CPI. TC was 73% for IRE group vs 56% for no IRE group (p = 0.0054). OS was significantly greater for IRE group during/after IL2 compared to no IRE/before IL2 in MM, med 46 months (mo) vs 18 mo (p = 0.0001) and in RCC, med 61 mo vs 43 mo (p = 0.0196), independent of CPI IREs. Med # of IL2 doses was 19 in no IRE group, 39 in IRE during IL2 group, and 25 in IRE after IL2 group. IL2-related IREs were primarily vitiligo and thyroid dysfunction (70% of IL2 IREs), with limited further impact, while CPI-related IREs were often serious, requiring intervention (hypophysitis, colitis, hepatitis, uveitis) (52% of CPI IREs) and possibly chronic management. Conclusions: IREs following IL2 are associated with improved TC and OS. IREs resulting from IL2 and from CPIs are qualitatively different and likely reflect different mechanisms of action of immune activation and response.

Introduction Evidence suggests that telemonitoring decreases mortality and heart failure (HF)-related hospital admission in patients with HF. However, most studies follow their patients for only several months. Little is known about the long-term effects of telemonitoring after a period of application. Methods In 2007, the TEHAF study was initiated to compare tailored telemonitoring with usual care with respect to time until first HF-related hospital admission. In total, 301 patients completed the study after a follow-up period of one year. No differences could be found in time to first HF-related admission between intervention and control groups. Here, we performed a retrospective analysis in order to investigate potential long-term effects of telemonitoring. The primary endpoint was time to first HF-related hospital admission. Secondary endpoints were, amongst others, all-cause mortality, hospital admission due to HF and days alive and out of hospital (DAOOH). Electronic files of all included patients were reviewed between October 2007 and September 2015. Result Mean follow-up duration was 1652 days (standard deviation: 1055 days). No significant difference in time to first HF-related hospital admission (log-rank test, p = 0.15), all-cause mortality (log-rank test, p = 0.43), or DAOOH (two-sample t-test, p = 0.87) could be found. However, patients that underwent telemonitoring had significantly fewer HF-related hospital admissions (incident rate ratio 0.54, 95% confidence interval 0.31–0.88). Discussion Telemonitoring did not significantly influence the long-term outcome in our study. Therefore, extending the follow-up period of telemonitoring studies in HF patients is probably not beneficial.

Abstract Background and Aims Peritoneal dialysis (PD) is beneficial for older adults with end-stage renal disease (ESRD) because it allows for dialysis treatment in their own homes. The risk factors associated with specific prognoses in elderly PD patients need to be explored to continue stably without adverse events. However, the risk of adverse events specific to older adults on PD has not been thoroughly investigated. The critical risk factor for ESRD and aging is decreased physical function. The purpose of this study was to assess the association between physical function and outcomes in older adults on PD. Methods This was a single-center, prospective observational cohort study. Stable, ambulatory patients undergoing PD between April 1, 2014, and September 31, 2016, were enrolled. Six-minute walk distance (6MWD), short physical performance battery (SPPB), lower extremity muscle strength (LES), and 10-meter walk speed were measured for each patient. Laboratory data were also collected. All subjects were followed up until death or the end of the follow-up period (December 31, 2019). This ethical institution at the Seire Christopher University approved all procedures performed in this study. Informed consent was obtained from all the patients. Baseline patient characteristics and physical function were compared using an unpaired t-test or Mann-Whitney U test. Receiver operating characteristic curve analysis on mortality prediction was performed to calculate the area under the curve in the significant value of the unpaired t-test or Mann-Whitney U test. We used the Youden index to determine the optimal cut-off point, and patients were categorized into 2 groups by each cut-off value. The relationship between all-cause mortality and each variable was studied using Kaplan-Meier analysis and the log-rank test. All tests were assessed at a statistical significance of p<0.05. Results Thirty-seven patients were enrolled. Three patients refused to participate in the study, and one patient was excluded because they had a medical reason. Therefore, 33 patients (age: 74.8 ± 5.9 years) were finally included in the present study. The median follow-up time was 39 months (interquartile range: 28–49 months), during which 19 (57.6%) deaths occurred. Death during follow-up was significantly associated with lower 6MWD (234.6.9±115.8 vs. 351.9±105.8 m), lower serum albumin (Alb, 2.7±0.6 vs. 3.2±0.4 mg/dL), and lower Geriatric Nutritional Risk Index (GNRI, 79.7±9.9 vs. 88.5±7.1) than those who did not die (died vs. not died group, respectively). No other variables were significantly different between the groups. The cut-off value, discriminating those at high risk of mortality, for the 6MWD was 338m, Alb was 3.0 ml/dL, and GNRI was 83.7. In the Kaplan-Meier survival analysis and log-rank test, 6MWD, Alb, and GNRI were significantly associated with all-cause mortality. Conclusion This is the first study, to our knowledge, to show that lower 6MWD scores were associated with all-cause mortality in older adults on PD, suggesting that objective exercise tolerance measures may be useful for the risk stratification of older adults undergoing PD. Although the results were obtained from a small sample size, this study has clinical significance because older adults on PD are rare. The 6MWD is a useful measurement that reflects exercise tolerance, has good reliability, has low cost, and is easily applicable. The results of this study support those of previous studies in other groups showing that 6MWD and nutritional status significantly predicted prognosis. Therefore, low exercise tolerance and malnutrition may represent an important therapeutic target in this population.

Chirurgische Entfernung

Die komplette chirurgische Entfernung von Lebermetastasen bietet Patienten nach kolorektalem Karzinom die einzige kurative Chance. Es gibt jedoch eine, anscheinend unbegrenzte, Anzahl an Parametern, die die Prognose dieser Patienten bestimmen und damit den Sinn dieser Therapie vorhersagen können. Zu den am häufigsten diskutierten und am einfachsten zu bestimmenden Parametern gehört die Anzahl der Metastasen. Ziel dieser Studie war es daher die Wertigkeit dieses Parameters in der Literatur zu reflektieren und unsere eigenen Patientendaten zu evaluieren. Insgesamt konnte von 302 Patienten ein komplettes Follow-up erhoben werden. Die gebildeten Patientengruppen wurden mit Hilfe einer Kaplan Meier Analyse und konsekutivem log rank Test untersucht. Die Literatur wurde bis Dezember 1998 revidiert. Die Anzahl der Metastasen bestätigte sich als ein prognostisches Kriterium. Lagen drei oder mehr Metastasen vor, so war nicht nur die Wahrscheinlichkeit einer R0 Resektion deutlich geringer (17.8% versus 67.2%) sondern auch das Überleben der Patienten nach einer R0 Resektion tendenziell unwahrscheinlicher. Das 5-Jahres Überleben betrug bei > 2 Metastasen 9% bei > 2 Metastasen 36%. Das 10-Jahres Überleben beträgt bislang bei > 2 Metastasen 0% bei > 2 Metastasen 18% (p < 0.07). Die Anzahl der Metastasen spielt in der Prognose der Patienten mit kolorektalen Lebermetastasen eine Rolle. Selbst bei mehr als vier Metastasen ist jedoch gelegentlich eine R0 Resektion möglich. In diesen Fällen kann der Patient auch langfristig von einer Operation profitieren. Das wichtigere Kriterium einer onkologisch sinnvollen Resektabilität ist die Frage ob technisch und funktionell eine R0 Resektion durchführbar ist. Ist das der Fall, so sollte auch einem Patienten mit mehreren Metastasen die einzige kurative Chance einer Resektion nicht vorenthalten bleiben.

Abstract Background Upgrade to resynchronization therapy (CRT) from conventional pacemaker (P) or defibrillator (D) is common practice in Europe. However, guidelines (GL) are discordant: Pacing GL give a class I recommendation, while Heart Failure (HF) GL provide a class IIb indication. Previous studies suggested worse outcomes in upgraded patients (pts). Aim To compare response rate and clinical outcomes in a cohort of pts receiving de novo or upgrade to CRT. Methods Single-center retrospective study of consecutive pts submitted to CRT implantation (2007–2017). Major adverse cardiac events (MACE) included HF hospitalization (HHF) or all-cause mortality. Clinical response was defined as New York Heart Association class improvement without MACE in the first year of follow-up (FU). Left ventricle end-systolic volume reduction of &gt;15% denoted echocardiographic (echo) response. Survival analysis with Kaplan-Meier method and Log-rank test was performed. Propensity-score matching (PSM) analysis was made to adjust for possible confounder variables. Results 230 CRT recipients (70.9% male, mean age 67±11 years, 71.5% non-ischemic cardiomyopathy, 39.6% CRT-P) were included, of whom 46 (20%) underwent an upgrade. Upgraded pts were older (69.8 vs 65.9 years, p=0.015), with higher rates of permanent atrial fibrillation (37.0% vs 12.7%, p=0.001), moderate to severe valve disease (45.7% vs 22.3%, p=0.002), chronic kidney disease (37.0% vs 17.2%, p=0.005) and treatment with mineralocorticoid receptor antagonists (79.1% vs 52.0%, p=0.002). They were more likely to receive CRT-P (65.2% vs 33.2%, p&lt;0.001) and CRT-D were more often implanted for secondary prevention (60.0% vs 17.9%, p=0.001). No differences emerged in procedural complications, clinical (74.4% vs 71.4%, p=0.712) or echo (66.7% vs 69.7%, p=0.822) response rates. During a median FU of 3±4 years, all-cause mortality was similar among groups (Log Rank test, p=0.522, unadjusted hazard ratio [HR] 1.25, confidence interval [CI] 95% 0.62–2.49, p=0.534). There was a statistical tendency for higher MACE rate in the upgrade group (Log Rank test, p=0.064, HR 1.66, CI 95% 0.95–2,91, p=0.076). No differences were found in lead dislodgement (10.9% vs 7.1%, p=0.368) or endocarditis (2.2% vs 4.3%, p=0.692) rates. PSM analysis identified 88 matched pairs (46 upgrade/42 de novo pts). In this cohort, all-cause mortality (Log Rank test, p=0.77, HR 0.89, CI 95% 0.39–2.03, p=0.78) and MACE (Log Rank test, p=0.36, HR 1.38, CI 95% 0.68–2.81, p=0.37) were comparable between groups [graph no. 1]. Conclusion Upgrade to CRT was similar to de novo implantation in terms of complications and clinical and echo response, in this cohort. The risk for MACE and mortality was also comparable.

Abstract Background CHA2DS2-VASc score has been used as a surrogate marker for predicting outcomes beyond thromboembolic risk in patients with atrial fibrillation (AF). Likewise, cardiac troponin I (cTnI) is a predictor of mortality in AF. Purpose This study aimed to investigate the association of cTnI and CHA2DS2-VASc score with long-term prognosis in patients admitted to the emergency department with AF. Methods A retrospective cohort study conducted between January 2012 and December 2013, enrolling patients admitted to the emergency department with AF and having documented cTnI measurements. CHA2DS2-VASc score was estimated. Primary endpoint was 5-year all-cause mortality, readmission for heart failure (HF), readmission for myocardial infarction (MI) and the composite end point of major adverse cardiac events defined as death, readmission for HF or readmission for MI (MACE). Results A total of 578 patients with AF were studied, of whom 252 patients had elevated levels of cTnI (43.6%) and 334 patients had CHA2DS2-VASc score >3 (57.8%). Patients with elevated cTnI tended to be oldercompared with those who did not have cTnI elevation and were more frequently comorbid and of higher ischemic risk, including hypertension, prior MI, prior HF, chronic renal failure and peripheral artery disease. The overall median CHA2DS2-VASc score was higher in those with cTnI elevation compared to those patients elevated cTnI levels (4.2 vs 3.3 points, p<0.001). Main diagnoses at hospital discharge were tachyarrhythmia 30.3%, followed by heart failure 17.7%, respiratory infections 9.5% and acute coronary syndrome 7.3%. At 5-year follow-up, all-cause death was significantly higher for patients with cTnI elevation compared with those who did not have cTnI elevation (56.4% vs. 27%; logrank test p<0.001). Specifically, for readmissions for HF and readmissions for MI there were no differences in between patients with or without cTnI elevation. In addition, MACE was reached in 165 patients (65.5%) with cTnI elevation, compare to 126 patients (38.7%) without cTnI elevation (p<0.001). On multivariable Cox regression analysis, cTnI elevation was an independent predictor of all-cause death (hazard ratio, 1.67, 95% confidence interval [CI]: 1.24–2.26, p=0.001) and of MACE (hazard ratio 1.47, 95% confidence interval 1.15–1.88; P=0.002), but it did not reach statistical significance for readmissions for MI and readmissions for HF. CHA2DS2-VASc score was a predictor on univariate Cox regression analysis for each endpoint, but it did not reach significance on multivariable Cox regression analysis for any endpoint. Conclusions cTnI is independently associated with long-term all-cause mortality in patients attending the emergency department with AF. cTnI compared to CHA2DS2-VASc score is thus a biomarker with predictive capacity for mortality in late follow-up, conferring utility in the risk stratification of patients with atrial fibrillation.

Abstract Background: Increased plasma troponin T (cTnT), but not troponin I (cTnI), is frequently observed in end-stage renal failure patients. Although generally considered spurious, we previously reported an associated increased mortality at 12 months. Methods: We studied long-term outcomes in 244 patients on chronic hemodialysis for up to 34 months, correlating the outcomes to plasma cTnT in routine predialysis samples. In addition, subsequent plasma samples at least 1 year later and within 6 months of data analysis were available in 97 patients and were used to identify patients with increasing plasma cTnT. The endpoints used were death and new or worsening coronary, cerebro-, and peripheral vascular disease and neuropathy. Results: Transplantation occurred more frequently in patients with low initial cTnT: 31%, 13%, and 3% in the groups with cTnT &lt;0.010, 0.010–0.099, and ≥0.100 μg/L, respectively. In the same groups, total deaths occurred in 6%, 43%, and 59% and cardiac deaths in 0%, 14%, and 24% of patients. In patients with follow-up samples, the group with increasing cTnT had a significantly increased death (relative risk, 2.0; P = 0.028). The increase was mainly in cardiac and sudden deaths. Conclusions: Higher plasma cTnT predicts long-term all-cause mortality in hemodialysis patients, even at concentrations &lt;0.100 μg/L, as does an increasing cTnT concentration over time.

Abstract Introduction Frailty is a major health determinant for cardiovascular disease. Thus far, data on frailty in patients with atrial fibrillation (AF) are limited. Aims To evaluate frailty in a large contemporary cohort of European AF patients, the relationship with oral anticoagulant (OAC) prescription and with risk of all-cause death. Methods We analyzed patients enrolled in the ESC-EHRA EORP-AF General Long-Term Registry. A 38-items frailty index (FI) was derived from baseline characteristics according to the accumulation of deficits model proposed by Rockwood and Mitnitsky. All-cause mortality was the primary study outcome. Results Out of the 11096 AF enrolled patients, data for evaluating frailty were available for 6557 (59.1%) patients who have been included in this analysis (mean [SD] age 68.9 [11.5], 37.7% females). Baseline median [IQR] CHA2DS2-VASc and HAS-BLED were 3 [2–4] and 1 [1–2], respectively. At baseline, median [IQR] FI was 0.16 (0.12–0.23), with 1276 (19.5%) patients considered “not-frail” (FI&lt;0.10), 4033 (61.5%) considered “pre-frail” (FI 0.10–0.25) and 1248 (19.0%) considered “frail” (FI≥0.25). Age, female prevalence, CHA2DS2-VASc and HAS-BLED progressively increased across the FI classes (all p&lt;0.001). Use of OAC progressively increased among FI classes; after adjustments FI was not associated with OAC prescription (odds ratio [OR]: 1.09, 95% confidence interval [CI]: 0.98–1.19 for each 0.10 FI increase). Conversely, FI was directly associated with vitamin K antagonist (VKA) use (OR: 1.26, 95% CI: 1.18–1.34 for each 0.10 FI increase) and inversely associated with non-VKA OACs (NOACs) use (OR: 0.82, 95% CI: 0.77–0.88). FI was significantly correlated with CHA2DS2-VASc (Rho= 0.516, p&lt;0.001). Over a median [IQR] follow-up of 731 [704–749] days, there were 569 (8.7%) all-cause death events. Kaplan-Meier curves [Figure] showed an increasing cumulative risk for all-cause death according to FI categories. A Cox multivariable analysis, adjusted for age, sex, type of AF and use of OAC, found that increasing FI as a continuous variable was associated with an increased risk of all-cause death (hazard ratio [HR]: 1.56, 95% CI: 1.40–1.73 for each 0.10 FI increase). An association with all-cause death risk was found across the FI categories (HR: 1.71, 95% CI: 1.23–2.38 and HR: 2.88, 95% CI: 2.02–4.12, respectively for pre-frail and frail patients compared to non-frail ones). FI was also predictive of all-cause death (c-index: 0.660, 95% CI: 0.637–0.682; p&lt;0.001). Conclusions In a European contemporary cohort of AF patients the burden of frailty is significant, with almost 1 out of 5 patients found to be “frail”. Frailty influenced significantly the choice of OAC therapy and was associated with (and predictive of) all-cause death at follow-up.

Introduction: The aim of this study was to examine whether the use of an internal electrostimulator could improve the results obtained with core decompression alone in the treatment of osteonecrosis of the femoral head. Methods: We performed a retrospective study of 41 patients (55 hips) treated for osteonecrosis of the femoral head between 2005 and 2014. Mean follow-up time was 56 (12-108) months. We recorded 3 parameters: time to recurrence of pain, time to conversion to arthroplasty and time to radiographic failure. Survival was estimated using the Kaplan-Meier method. The equality of the survival distributions was determined by the Log rank test. Results: Implanted electrostimulator was a factor that increased the survival of hips in a pre-op Steinberg stage of II or below, while it remained unchanged if the stage was III or higher. Conclusions: The addition of an internal electrostimulator provides increased survival compared to core decompression alone at stages below III.

AbstractPrevious studies on the adverse events of acute pulmonary embolism (APE) were mostly limited to single marker, and short follow-up duration, from hospitalization to up to 30 days. We aimed to predict the long-term prognosis of patients with APE by joint assessment of D-dimer, N-Terminal Pro-Brain Natriuretic Peptide (NT-ProBNP), and troponin I (cTnI). Newly diagnosed patients of APE from January 2011 to December 2015 were recruited from three hospitals. Medical information of the patients was collected retrospectively by reviewing medical records. Adverse events (APE recurrence and all-cause mortality) of all enrolled patients were followed up via telephone. D-dimer > 0.50 mg/L, NT-ProBNP > 500 pg/mL, and cTnI > 0.40 ng/mL were defined as the abnormal. Kaplan–Meier curve was used to compare the cumulative survival rate between patients with different numbers of abnormal markers. Cox proportional hazard regression model was used to further test the association between numbers of abnormal markers and long-term prognosis of patients with APE after adjusting for potential confounding. During follow-up, APE recurrence and all-cause mortality happened in 78 (30.1%) patients. The proportion of APE recurrence and death in one abnormal marker, two abnormal markers, and three abnormal markers groups were 7.69%, 28.21%, and 64.10% respectively. Patients with three abnormal markers had the lowest survival rate than those with one or two abnormal markers (Log-rank test, P < 0.001). After adjustment, patients with two or three abnormal markers had a significantly higher risk of the total adverse event compared to those with one abnormal marker. The hazard ratios (95% confidence interval) were 6.27 (3.24, 12.12) and 10.7 (4.1, 28.0), respectively. Separate analyses for APE recurrence and all-cause death found similar results. A joint test of abnormal D-dimer, NT-ProBNP, and cTnI in APE patients could better predict the long-term risk of APE recurrence and all-cause mortality.
