Higher 1-year Mortality Research Articles

Prognostic impact of preoperative respiratory colonization on early-onset pneumonia after lung transplantation.

BackgroundThe number of lung transplantation procedures is rapidly increasing worldwide. Little is known about the effect of perioperative respiratory microbial colonization on pneumonia during lung transplantation. We evaluated the microbiome composition and incidence of early pneumonia in patients undergoing lung transplantation. We investigated factors related to post-transplant pneumonia (PTP) after lung transplantation.MethodsA retrospective analysis of patients subjected to lung transplantation between May 2013 and December 2019 was performed. Perioperative microbial colonization, and its relationship with early pneumonia, were examined in specimens from bronchial washing, bronchoalveolar lavage, and sputum aspiration before and after surgery. One-year mortality, as the primary outcome, was analyzed using the Kaplan-Meier curve model.ResultsAmong 76 patients who underwent lung transplantation, 34 donors (44.7%) and 28 recipients (36.8%) showed positive respiratory cultures with respect to preoperative respiratory colonization. A separate analysis of donors and recipients showed that 42 donors and 48 recipients were in respiratory non-colonized state, and 28 (53.8%) donors and 36 (69.2%) recipients survived 1 year after lung transplantation. Acinectobacter baumannii was the most common respiratory multidrug-resistant (MDR) pathogen. PTP was significantly lower in the survivor group (38.5% vs. 70.8%, P=0.009). Out of the recipients with preoperative respiratory colonization, 57.1% survived 1 year after lung transplantation. Patients with PTP had significantly higher 1-year mortality than those without PTP (P=0.009). Preoperative respiratory colonization of the recipients (P=0.010) and PTP patients (P=0.005) was associated with high 1-year mortality rate. Perioperative respiratory colonization of donors was not associated with the incidence of PTP and 1-year survival.ConclusionsPerioperative colonization of recipients was a powerful predictive factor for PTP, which was associated with 1-year mortality in patients subjected to lung transplantation. Our results suggest that donor acceptance criteria may change to better address potential shortages in organ donation.

The impact of IgG subclass deficiency on the risk of mortality in hospitalized patients with COPD

BackgroundImmunoglobulin G (IgG) deficiency increases the risk of acute exacerbations and mortality in chronic obstructive pulmonary disease (COPD). However, the impact of IgG subclass deficiency on mortality in COPD is unknown. Here, we determined which IgG subclass, if any, is associated with increased risk of mortality in COPD.MethodsWe measured serum IgG subclass concentrations of 489 hospitalized patients with COPD who were enrolled in the Rapid Transition Program (clinicaltrials.gov identifier NCT02050022). To evaluate the impact of IgG subclass deficiency on 1-year mortality, Cox proportional hazards regression analyses were performed with adjustments for potential confounders.ResultsDeficiencies in IgG1, IgG2, IgG3, and IgG4 were present in 1.8%, 12.1%, 4.3%, and 11.2% of patients, respectively. One-year mortality was 56% in patients with IgG1 deficiency, 27% in IgG2 deficiency, 24% in IgG3 deficiency, and 31% in IgG4 deficiency. Cox proportional modeling showed that IgG1 and IgG4 deficiencies increased the 1-year mortality risk with an adjusted hazard ratio of 3.92 (95% confidence interval [CI] = 1.55–9.87) and 1.74 (95% CI = 1.02–2.98), respectively. Neither IgG2 nor IgG3 deficiency significantly increased 1-year mortality. Two or more IgG subclass deficiencies were observed in 5.3%. Patients with 2 or more IgG subclass deficiencies had a higher 1-year mortality than those without any deficiencies (46.2% vs. 19.7%, p < 0.001), with an adjusted hazard ratio of 2.22 (95% CI = 1.18–4.17).ConclusionsIgG1 and IgG4 deficiency was observed in 1.8% and 11.2% of hospitalized patients with COPD, respectively, and these deficiencies were associated with a significantly increased risk of 1-year mortality.

Management of Inpatient Macroscopic Haematuria: A Typical Urology Emergency With a High Mortality

ObjectiveTo review the in-patient (IP) management patterns and 30-day outcomes of patients admitted with macroscopic haematuria (MH) over a 1-year-period in a single-institution, aiming to clarify management for such cases in the future. MethodsRetrospective cohort study was conducted on all patients admitted with MH in a single-institution over 1-year, excluding patients not requiring an overnight stay. A case note review was performed for patient demographics, MH investigations, and management. ResultsA total of 120 patients were admitted with MH over a span of 1-year. 89% (107/120) were males, with an average age of 78 years (36-97 years), an average ASA of 3, mean length-of-stay (LOS) was 5 days (1-31days) and 68% (82/120) had pre-existing urological conditions. 62% (74/120) required bladder irrigation for a mean duration of 3 days (1-16days). 10% (12/120) required an emergency rigid cystoscopy and washout to manage the bleeding, of which 4% (5/12) had malignancy noted. Over 8% (10/120) patients discharged had unplanned readmissions within 30 days. The 1-year mortality for this cohort was 23% (28/120) of which 21% (6/28) died within 30 days from discharge. ConclusionIP MH affects a vulnerable patient cohort. There is no specific pathway guiding the inpatient management of MH; therefore, research is required to produce standardized pathways for managing MH, considering the high-risk patient cohort, the prolonged LOS, and high 1-year mortality rate.

Mortality rates among non-Hispanic Black and White persons in carbapenemase-producing Enterobacterales, Tennessee, 2015–2019

Background: Carbapenem-resistant Enterobacterales (CRE) are an urgent public health threat, particularly those that produce carbapenemase (CP-CRE). Certain risk factors associated with CRE acquisition have been well described, such as older age, indwelling devices, prior hospitalizations, and underlying conditions. However, data are limited regarding the association of CRE and health disparities, such as race and ethnicity. Published literature has consistently shown that minority groups, including but not limited to Non-Hispanic Black persons, have higher risks of developing adverse health outcomes. To better understand the impact of race and ethnicity in CP-CRE cases, we compared 1-year mortality rates among Non-Hispanic Blacks and Non-Hispanic Whites. Methods: CRE are reportable in Tennessee; isolates must be sent to the State Public Health Laboratory for carbapenemase detection and resistance mechanism testing. We linked 2015–2019 CP-CRE surveillance cases and laboratory data from our statewide surveillance system, the National Disease Surveillance System (NEDDS)-Base System, with the Tennessee Hospital Discharge Data System (HDDS) and vital records databases. Database linkage and data analyses were performed using SAS version 9.4 software. Results: Among 615 CP-CRE cases, the mean age was lower among non-Hispanic Blacks (59 years; SD, 16.6) compared to non-Hispanic Whites (mean, 65 years; SD, 15.7). Among 156 non-Hispanic Blacks with CP-CRE, 101 (64.7%) were nursing home residents, whereas 281 (71.1%) among the 395 non-Hispanic Whites were nursing home residents. Also, 64 Non-Hispanic Blacks (41%) died within 1 year of their first specimen collection date compared to 92 Non-Hispanic Whites (23.3%). Non-Hispanic Blacks with CP-CRE who died within 1 year had a mortality rate of 5.6 per 100,000 (95% CI, 4.21–6.94) Black population, which was 1.6 times higher than Non-Hispanic White persons at 3.5 per 100,000 (95% CI, 2.94–3.95; χ2P &lt; .001) White population. Conclusions: Despite a lower mean age, non-Hispanic Black CP-CRE cases had a higher 1-year mortality rate than non-Hispanic Whites. Racial and ethnicity data often are missing or incomplete from surveillance data. Data linkages can be a valuable tool to gather additional clinical and demographic data that may be missing from public health surveillance data to improve our understanding of health disparities. Recognition of these health disparities among CRE can provide an opportunity for public health to create more targeted interventions and educational outreach.Funding: NoneDisclosures: None

Patients with rheumatic disease experiencing ST-elevation myocardial infarction have increased inflammatory- and neurohormonal response and higher 1-year mortality

Abstract Funding Acknowledgements Type of funding sources: Foundation. Main funding source(s): This work was supported by Righospitalets Forskningsfond (Grant number: 07IO). Lundbeck Foundation (R186-2015-2132). Background Patients with rheumatoid diseases have been reported to have increased risk of ST-elevation myocardial infarction (STEMI). However, little is known about mortality risk following STEMI in these patients. Furthermore, STEMI patients with increased neurohormonal- and inflammatory response have higher mortality compared to patients with low response. Purpose We sought to assess whether patients with a rheumatic disease (RD) have an increased inflammatory- and neurohormonal response to a STEMI and whether 1-year mortality was higher in these patients compared to patients without rheumatic disease. Methods In 1700 consecutive STEMI patients (comatose cardiac arrest- and cardiogenic shock patients were excluded) from two Danish tertiary heart centres were studied. Biomarkers reflecting neurohormonal activation (pro-atrial natriuretic peptide (proANP), copeptin, and mid-regional pro-adrenomedullin (MRproADM)) and inflammatory response (C-reactive protein (CRP) and ST2) were measured at in the catheterization laboratorium before the acute coronary angiogram was performed. Patients were stratified according to known RD or not. Results In total, 88 (5.2%) STEMI patients had a RD diagnosis. From these 28 (32%) had RA, 9 (10%) had psoriasis arthritis, and 23 (26%) had gout, while 28 (32%) had other RDs. Patients in the two groups were similar of age (no RD vs. RD, mean (SD): 63 (13) vs. 65 (14) years, p=0.22), mostly male (n (%) 1194 (74) vs 57 (66), p=0.08) with similar number of comorbidities, same LVEF (median (IQR) 50 (40-55) vs. 50 (40-55), p=0.58), and similar infarct size (maximum troponin T concentration 3050 (1150-6885) vs. 3030 (1500-7260) ng/L, p=0.79). In RD patients, admission concentration of MRproADM (median (IQR) 0.77 (0.63-0.98) vs. 0.71 (0.58-0.90) nmol/L, p=0.04), ST2 (43 (33-64) vs 39 (29-55) ng/ml, p=0.04), and CRP (6.8 (2.9-14) vs 3.3 (1.4-8.2) mg/L, p&amp;lt;0.0001) was higher compared to patients without RD. No difference in proANP and copeptin was detected. One-year all-cause mortality was higher in patients with RD (11% vs. 5.5%, p=0.02). When including patients with CS and patients comatose after cardiac arrest, the signal remained intact. Conclusion STEMI patients with RD have higher admission inflammatory response and neurohormonal activation compared to patients without. Furthermore, patients with RD have higher 1-year all-cause mortality.

Left atrial function index (LAFI) and outcome in patients undergoing transcatheter aortic valve replacement

BackgroundClinical data regarding the association between the left atrial function index (LAFI) and outcome in patients undergoing transcatheter aortic valve replacement (TAVR) are limited.ObjectivesWe aimed to investigate the association between the left atrial function index (LAFI) and outcome in patients undergoing TAVR.MethodsIn this retrospective multicenter study, we assessed baseline LAFI in 733 patients undergoing TAVR for severe aortic stenosis in two German high-volume centers between 2008 and 2019. Based on receiver operating characteristic curves, patients were stratified according to their baseline LAFI into two groups (LAFI ≤ 13.5 vs. LAFI > 13.5) and assessed for post-procedural outcome. The primary endpoint of our study was the 1-year all-cause mortality.ResultsPatients with a LAFI ≤ 13.5 had significantly more often atrial fibrillation (p < 0.001), lower LVEF (p < 0.001) and higher levels of NT-proBNP (p < 0.001). After TAVR, a significant improvement in the LAFI as compared to baseline was observed at 12 months after the procedure (28.4 vs. 32.9; p = 0.001). Compared to patients with a LAFI > 13.5, those with a LAFI ≤ 13.5 showed significantly higher rate of 1-year mortality (7.9% vs. 4.0%; p = 0.03). A lower LAFI has been identified as independent predictor of mortality in multivariate analysis (HR (95% CI) 2.0 (1.1–3.9); p = 0.03).ConclusionA reduced LAFI is associated with adverse outcome and an independent predictor of mortality in TAVR patients. TAVR improves LAFI within 12 months after the procedure.Graphical abstractLeft Atrial Function Index (LAFI) in Patients undergoing Transcatheter Aortic Valve Implantation.

CALL-K score: predicting the need for renal replacement therapy in cardiogenic shock.

The clinical predictors and outcomes of patients with cardiogenic shock (CS) requiring renal replacement therapy (RRT) have not been studied previously. This study assesses the impact of RRT on mortality in patients with CS and aims to identify clinical factors that contribute to the need of RRT. Consecutive patients presenting with CS were included from a prospective registry of cardiac intensive care unit admissions at a single institution between 2014 and 2020. Of the 1030 patients admitted with CS, 123 (11.9%) received RRT. RRT was associated with higher 1-year mortality [adjusted hazard ratio = 1.62, 95% confidence interval (CI) 1.02-2.14], and a higher in-hospital incidence of sepsis [risk ratio = 2.76, P < 0.001], and pneumonia (risk ratio = 2.9, P = 0.001). Those who received RRT were less likely to receive guideline-directed medical treatment at time of discharge, undergo heart transplantation (2.4% vs. 11.5%, P = 0.002) or receive a durable left ventricular assist device (0.0% vs. 11.6%, P < 0.001). Five variables at admission best predicted the need for RRT (age, lactate, haemoglobin, use of pre-admission loop diuretics, and admission estimated glomerular filtration rate) and were used to generate the CALL-K 9-point risk score, with better discrimination than creatinine alone (P = 0.008). The score was internally validated (area under the curve = 0.815, 95% CI 0.739-0.835) with good calibration (Hosmer-Lemeshow P = 0.827). RRT is associated with worse outcomes, including a lower likelihood to receive advanced heart failure therapies in patients with CS. A risk score comprising five variables routinely collected at admission can accurately estimate the risk of needing RRT.

Bacteraemia and quick Sepsis Related Organ Failure Assessment (qSOFA) are independent risk factors for long-term mortality in very elderly patients with suspected infection: retrospective cohort study

BackgroundIn older adult patients, bloodstream infections cause significant mortality. However, data on long-term prognosis in very elderly patients are scarce. This study aims to assess 1-year mortality from bacteraemia in very elderly patients.MethodsRetrospective cohort study in inpatients aged 80 years or older and suspected of having sepsis. Patients with (n = 336) and without (n = 336) confirmed bacteraemia were matched for age, sex, and date of culture, and their characteristics were compared. All-cause mortality and risk of death were assessed using the adjusted hazard ratio (aHR).ResultsCompared to controls, cases showed a higher 1-year mortality (34.8% vs. 45.2%) and mortality rate (0.46 vs. 0.69 deaths per person-year). Multivariable analysis showed significant risk of 1-year mortality in patients with bacteraemia (aHR: 1.31, 95% confidence interval [CI] 1.03–1.67), quick Sepsis Related Organ Failure Assessment (qSOFA) score of 2 or more (aHR: 2.71, 95% CI 2.05–3.57), and age of 90 years or older (aHR 1.53, 95% CI 1.17–1.99).ConclusionsIn elderly patients suspected of sepsis, bacteraemia is associated with a poor prognosis and higher long-term mortality. Other factors related to excess mortality were age over 90 years and a qSOFA score of 2 or more.

Very early infective endocarditis after transcatheter aortic valve replacement.

Scarce data exist about early infective endocarditis (IE) after trans-catheter aortic valve replacement (TAVR). The objective was to evaluate the characteristics, management, and outcomes of very early (VE) IE (≤ 30days) after TAVR. This multicenter study included a total of 579 patients from the Infectious Endocarditis after TAVR International Registry who had the diagnosis of definite IE following TAVR. Ninety-one patients (15.7%) had VE-IE. Factors associated with VE-IE (vs. delayed IE (D-IE)) were female gender (p = 0.047), the use of self-expanding valves (p < 0.001), stroke (p = 0.019), and sepsis (p < 0.001) after TAVR. Staphylococcus aureus was the main pathogen among VE-IE patients (35.2% vs. 22.7% in the D-IE group, p = 0.012), and 31.2% of Staphylococcus aureus infections in the VE-IE group were methicillin-resistant (vs. 14.3% in the D-IE group, p = 0.001). The second-most common germ was enterococci (34.1% vs. 24.4% in D-IE cases, p = 0.05). VE-IE was associated with very high in-hospital (44%) and 1-year (54%) mortality rates. Acute renal failure following TAVR (p = 0.001) and the presence of a non-enterococci pathogen (p < 0.001) were associated with an increased risk of death. A significant proportion of IE episodes following TAVR occurs within a few weeks following the procedure and are associated with dismal outcomes. Some baseline and TAVR procedural factors were associated with VE-IE, and Staphylococcus aureus and enterococci were the main causative pathogens. These results may help to select the more appropriate antibiotic prophylaxis in TAVR procedures and guide the initial antibiotic therapy in those cases with a clinical suspicion of IE. Very early infective endocarditis after trans-catheter aortic valve replacement. VE-IE indicates very early infective endocarditis (≤30 days post TAVR). D-IE indicates delayed infective endocarditis.

Soluble ST2 as a Potential Biomarker for Risk Assessment of Pulmonary Hypertension in Patients Undergoing TAVR?

Background: Severe aortic valve stenosis (AS) is associated with pulmonary hypertension (PH) and has been shown to limit patient survival. Soluble suppression of tumorigenicity-2 (sST2) is a cardiovascular biomarker that has proven to be an important prognostic marker for survival in patients undergoing transcatheter aortic valve replacement (TAVR). The aim of this study was to assess the importance of the sST2 biomarker for risk stratification in patients with severe AS in presence or absence of PH. Methods: In 260 patients with severe AS undergoing TAVR procedure, sST2 serum level concentrations were analyzed. Right heart catheter measurements were performed in 152 patients, with no PH detection in 43 patients and with PH detection in 109 patients. Correlation analyses according to Spearman, AUROC analyses and Kaplan–Meier curves were calculated. Results: Patients with severe AS and PH showed significantly higher serum sST2 concentrations (p = 0.006). The sST2 cut-off value for non-PH patients regarding 1-year survival yielded 5521.15 pg/mL, whereas the cut-off value of PH patients was at a considerably higher level of 10,268.78 pg/mL. A cut-off value of 6990.12 pg/mL was related with a significant probability of PH presence. Survival curves showed that patients with severe AS and PH not only had higher 1-year mortality, but also that increased levels of sST2 plasma concentration were associated with earlier death. Conclusion: sST2 definitely has the potential to provide information about the presence of PH in patients with severe AS, in a noninvasive way.

Molybdenum cofactor deficiency: A natural history.

Molybdenum cofactor deficiency (MoCD) includes three ultrarare autosomal recessive inborn errors of metabolism (MoCD type A [MoCD‐A], MoCD‐B, and MoCD‐C) that cause sulfite intoxication disorders. This natural history study analyzed retrospective data for 58 living or deceased patients (MoCD‐A, n = 41; MoCD‐B, n = 17). MoCD genotype, survival, neuroimaging, and medical history were assessed retrospectively. Prospective biomarker data were collected for 21 living MoCD patients. The primary endpoint was survival to 1 year of age in MoCD‐A patients. Of the 58 MoCD patients, 49 (MoCD‐A, n = 36; MoCD‐B, n = 13) had first presenting symptoms by Day 28 (neonatal onset; median: 2 and 4 days, respectively). One‐year survival rates were 77.4% (overall), 71.8% (neonatal onset MoCD‐A), and 76.9% (neonatal onset MoCD‐B); median ages at death were 2.4, 2.4, and 2.2 years, respectively. The most common presenting symptoms in the overall population were seizures (60.3%) and feeding difficulties (53.4%). Sequelae included profound developmental delay, truncal hypotonia, limb hypertonia that evolved to spastic quadriplegia or diplegia, dysmorphic features, and acquired microcephaly. In MoCD‐A and MoCD‐B, plasma and urinary xanthine and S‐sulfocysteine concentrations were high; urate remained below the normal reference range. MOCS1 mutation homozygosity was common. Six novel mutations were identified. MoCD is a severe neurodegenerative disorder that often manifests during the neonatal period with intractable seizures and feeding difficulties, with rapidly progressive significant neurologic disabilities and high 1‐year mortality rates. Delineation of MoCD natural history supports evaluations of emerging replacement therapy with cPMP for MoCD‐A, which may modify disease course for affected individuals.

Evaluation of the Comprehensive Geriatric Assessment (CGA) tool as a predictor of postoperative complications following major oncological abdominal surgery in geriatric patients.

IntroductionThe concept of frailty extends beyond chronological age. Identifying frailty using a two-step approach, starting with the use of a screening tool (G8) followed by comprehensive geriatric assessment (CGA), may be useful in guiding treatment decisions and follow-up. This study evaluated the association between G8 and CGA, and the risk of 90-day postoperative complications risk, in oncogeriatric patients.MethodsData on geriatric patients with major oncological abdominal surgery was retrospectively collected from our hospital records between 2016 and 2019. Patients with an impaired G8 screening score, who subsequently underwent CGA geriatric screening, were included. Postoperative complications were classified using the Clavien-Dindo classification (CD), and the Comprehensive Complication Index (CCI). The association between the individual components of the geriatric assessment tools and the 90-day postoperative complications risk was analyzed.ResultsOne hundred and twelve patients, aged ≥ 70 years, operated for an intra-abdominal tumor with curative intent, were included. Seventy-six patients (67.9%) presented with an impaired G8, out of whom sixty-six (58.9%) had a CGA performed. On univariate analysis, altered nutritional status assessed by the Mini-Nutritional Assessment-Short Form was the only variable associated with higher postoperative total complication rate (p = 0.01). Patients with an impaired G8 had significantly more postoperative complications and higher 1-year mortality rates than patients with normal G8. Fifteen patients (13.4%) had grade III-IVb complications. A CCI > 50 was recorded in 16 patients (14.3%). All-cause 90-day postoperative mortality was 10.7%.ConclusionIdentifying an altered preoperative nutritional status, as part of the CGA, in patients screening positive for frailty, is a potentially modifiable risk factor that can enhance preoperative management and optimize treatment decision making. G8 may be a predictive factor for postoperative complications in oncogeriatric patients.

Primary PCI in the very elderly: A study of outcomes in patients aged &amp;gt; 85 years with STEMI

Abstract Funding Acknowledgements Type of funding sources: None. Background Primary percutaneous coronary intervention (PPCI) as management for acute STEMI is a well-established, evidence-based treatment offered across India. Evidence of benefit in the very elderly is sparse. With an aging population, the demand on PPCI services for STEMI in the elderly is likely to increase. Our aim was to establish real life outcomes in patients aged 85 years and older who receive PPCI for acute STEMI. Methods Data was collected retrospectively on all patients aged 85 years and older who were referred and accepted for PPCI to our centre between 2015 and 2019. This represented 11.2% (N = 572) of all accepted PPCI referrals over the 4-year period. Results 64 patients proceeded to invasive angiography, of whom 43 patients received PPCI. PPCI was successful in over 95% of cases. Median hospital stay of all patients was 5 days (range 3– 15). 38 patients survived STEMI admission (88.4%). 94% of patients who survived admission were discharged to their own home, and 72% were functionally independent. One-year mortality was 33.7%. Median survival of all patients post-STEMI was 3.45 years. Conclusions Advanced age should not be used as an exclusion criterion in isolation for PPCI. Rather, a personalised approach that takes into account all clinically relevant patient factors should be adopted to guide PCI decision-making. Despite relatively long hospital stays and high 1-year mortality, there are still potential good quality life years to be gained following intervention. Our findings therefore suggest that emergency revascularization therapy as first-line treatment for STEMI in the very elderly should be considered routinely

Incidence, clinical impact and predictors of thrombocytopenia after transcatheter aortic valve replacement

BackgroundThrombocytopenia is a common, yet poorly understood, complication after transcatheter aortic valve replacement (TAVR). Balloon-expandable transcatheter heart valve has been associated with higher incidence of thrombocytopenia, compared with self-expandable valves. The aim of this study was to analyze the incidence, clinical impact and predictors of acquired thrombocytopenia in patients undergoing TAVR. MethodsWe performed an observational study from consecutive patients with severe aortic stenosis undergoing TAVR (n = 679) in a single center. Association and best cut-off point of platelet decrease with early mortality was analyzed. Patients were classified according to postprocedural percentage decrease in platelet count (PDPC), comparing clinical outcomes and analyzing predictors of platelet decrease. ResultsThe median PDPC was 37.1 [IQR: 27.4–46.9]. PDPC was associated with early mortality (OR: 2.1, 95%IC: 1.7–2.5 for each 10% decrease, AUC:0.81, 95%CI:0.72–0.89) with an optimal cut-off point of 46%. PDPC≥46% and late nadir (≥4 days) were both independent predictors of early mortality (OR: 6.0 [IQR: 2.4–14.9] and OR: 5.1 [IQR: 2.2–11.6], respectively). The combination of both factors (PDPC≥46% and nadir ≥4 day) was associated with higher 2-year mortality (55.7%) compared to an early significant nadir (PDPC≥46% and nadir <4 day, 28.9%) and non-significant nadir (PDPC<46%, 21.0%), p < 0.001. Independent predictors of PDPC≥46% were baseline platelet count, Portico™, Abbott valve, intraprocedural major vascular complication and residual aortic regurgitation ≥grade 2. ConclusionThe platelet count decreased almost 40% after TAVR. Late nadir and PDPC≥46% predicted short-term clinical outcomes. Concomitant late and significant platelet decrease was associated with mid-term mortality.

Impact of Pretransplant Malignancy on Heart Transplantation Outcomes: Contemporary United Network for Organ Sharing Analysis Amidst Evolving Cancer Therapies.

An aging population and improved cancer survivorship have increased the number of individuals with treated malignancy who develop advanced heart failure. The benefits of heart transplantation (HT) in patients with a pretransplant malignancy (PTM) must be balanced against risks of posttransplant malignancy in the setting of immunosuppression. Adult patients in the United Network for Organ Sharing registry who received HT between January 1, 2010, and December 31, 2020 were included. Trends, patient characteristics, and posttransplant outcomes in HT recipients with PTM were evaluated. From 2000 to 2020, the proportion of HT recipients with PTM increased from 3.2% to 8.2%. From 2010 to 2020, 2113 (7.7%) of 27 344 HT recipients had PTM. PTM was associated with higher rates of 1-year mortality after HT (11.9% versus 9.2%; adjusted hazard ratio, 1.25 [95% CI, 1.09-1.44], P=0.001), driven by increased mortality in patients with hematologic PTM (adjusted hazard ratio, 2.00 [95% CI, 1.61-2.48]; P<0.001). For recipients who survived the first year, 5-year survival was similar between patients with and without PTM. Rates of malignancy at 5-years posttransplant were higher in the PTM group (20.4% versus 13.1%; adjusted hazard ratio, 1.57 [95% CI, 1.38-1.79], P<0.001). Prevalence of PTM in HT recipients nearly tripled over the past 2 decades. Patients with hematologic PTM were at increased risk of early mortality after HT. Patients with PTM were also at higher risk for posttransplant malignancy. Guidelines that reflect contemporary oncological care are needed to inform care of this heterogenous and expanding group of individuals.

Criteria for Iron Deficiency in Patients With Heart Failure

BackgroundGuidelines on heart failure (HF) define iron deficiency (ID) as a serum ferritin <100 ng/mL or, when 100-299 ng/mL, a transferrin saturation (TSAT) <20%. Inflammation (common in HF) may hinder interpretation of serum ferritin. ObjectivesThis study sought to investigate how different definitions of ID affect its prevalence and relationship to prognosis in ambulatory patients with chronic HF. MethodsPrevalence, relationship with patients’ characteristics, and outcomes of various ID definitions were evaluated among patients with HF referred to a regional clinic (Hull LifeLab) from 2001 to 2019. ResultsOf 4,422 patients with HF (median age 75 years [range: 68-82 years], 60% men, 32% with reduced left ventricular ejection fraction), 46% had TSAT <20%, 48% had serum iron ≤13 μmol/L, 57% had serum ferritin <100 ng/mL, and 68% fulfilled current guideline criteria for ID, of whom 35% had a TSAT >20%. Irrespective of definition, ID was more common in women and those with more severe symptoms, anemia, or preserved ejection fraction. TSAT <20% and serum iron ≤13 μmol/L, but not guideline criteria, were associated with higher 5-year mortality (HR: 1.27; 95% CI: 1.14-1.43; P < 0.001; and HR: 1.37; 95% CI: 1.22-1.54; P < 0.001, respectively). Serum ferritin <100 ng/mL tended to be associated with lower mortality (HR: 0.91; 95% CI: 0.81-1.01; P = 0.09). ConclusionsDifferent definitions of ID provide discordant results for prevalence and prognosis. Definitions lacking specificity may attenuate the benefits of intravenous iron observed in trials while definitions lacking sensitivity may exclude patients who should receive intravenous iron. Prespecified subgroup analyses of ongoing randomized trials should address this issue.

Selection and outcome of implantable cardioverter-defibrillator patients with and without cardiac resynchronization therapy: Comparison of 4384 patients from the German Device Registry to randomized controlled trials.

Registry data add important information to randomized controlled trials (RCT) on real-life aspects of implantable cardioverter-defibrillator (ICD) patients with and without cardiac resynchronization therapy (CRT-D). This analysis of the prospectively conducted German Device Registry aims at comparing mortality rates, comorbidities, complication rates to results from RCT. The German Device registry (DEVICE) prospectively collected data on ICD and CRT-D first implantations from 50 German centres. Demographic data, details on cardiac disease, electrocardiogram (ECG), medication, and data about procedure, complications, and hospital stay were stored in electronic case report forms. One year after device implantation patients were contacted for follow-up. DEVICE included n = 4384 first ICD/CRT-D implantations (29.3% CRT-D devices). We found a strong adherence to guidelines with over 90% of patients being on ß-blocker and ACE-inhibitor medication and adequate QRS width in the majority of CRT-D patients. Patients receiving a CRT-D were older (67.6 ± 11.0 years vs. 63.9 ± 13.4 years, p < .001) and had lower ejection fractions (mean 25% vs. 30%, p < .001) compared to ICD patients. Dilated cardiomyopathy was the predominant underlying heart disease in CRT-D (53.3%), coronary artery disease in ICD patients (64.7%). Compared to RCT our DEVICE patients had more comorbidities (17.9% chronic kidney disease [CKD]) and higher 1-year mortality rates (10.7% ICD group, 12.3% CRT group). In multivariate analysis, CKD patients had an almost 2-fold higher risk of 1-year mortality. Despite relevant limitations of registry data, DEVICE highlights important differences between RCT and real-world registry data and the impact of comorbidities on mortality of ICD and CRT-D recipients.

Daptomycin-Resistant Enterococcus Bacteremia Is Associated With Prior Daptomycin Use and Increased Mortality After Liver Transplantation.

BackgroundRisk factors for acquisition of vancomycin-resistant Enterococcus (VRE) include immunosuppression, antibiotic exposure, indwelling catheters, and manipulation of the gastrointestinal tract, all of which occur in liver transplant recipients. VRE infections are documented in liver transplantation (LT); however, only one single center study has assessed the impact of daptomycin-resistant Enterococcus (DRE) in this patient population.MethodsWe conducted a retrospective multicenter cohort study comparing liver transplant recipients with either VRE or DRE bacteremia. The primary outcome was death within 1 year of transplantation. Multivariable logistic regression analyses were performed to calculate adjusted odds ratios for outcomes of interest.ResultsWe identified 139 cases of Enterococcus bacteremia following LT, of which 78% were VRE and 22% were DRE. When adjusted for total intensive care unit days in the first transplant year, liver-kidney transplantation, and calcineurin inhibitor use, patients with DRE bacteremia were 2.65 times more likely to die within 1 year of transplantation (adjusted odds ratio [aOR], 2.648; 95% CI, 1.025–6.840; P = .044). Prior daptomycin exposure was found to be an independent predictor of DRE bacteremia (aOR, 30.62; 95% CI, 10.087–92.955; P < .001).ConclusionsIn this multicenter study of LT recipients with Enterococcus bacteremia, DRE bacteremia was associated with higher 1-year mortality rates when compared with VRE bacteremia. Our data provide strong support for dedicated infection prevention and antimicrobial stewardship efforts for transplant patients. Further research is needed to support the development of better antibiotics for DRE and practical guidance focusing on identification and prevention of colonization and subsequent infection in liver transplant recipients at high risk for DRE bacteremia.

Association of Mortality and Charlson Comorbidity Index in Surgical Spinal Trauma Patients at a Level I Academic Center.

The Charlson Comorbidity Index score (CCI) records the presence of comorbidities with various weights for a total score to estimate mortality within 1 year of hospital admission. Our study sought to assess the association of CCI with mortality rates of patients undergoing surgical intervention. Retrospective study. Retrospective study of patients with surgical spinal trauma at a large academic level I trauma tertiary center from 2015 to 2018. Information collected included age, sex, American Society of Anesthesiologists physical status, body mass index, Charlson comorbidities, injury severity score, the presence of spinal cord injury, and mortality. Mortality was measured at 30 days, 90 days, and 1 year. Descriptive and bivariate analyses were completed. The results were significant at P < 0.05. The highest proportion of 1-year mortality was in the patients with cervical (11.3%) and thoracolumbar injuries (7.4%) (P = 0.002). Patients with low CCI had low 1-year mortality (1.7%). Patients with high CCI had high 1-year mortality (13.8%) (P < 0.001). A significant association existed between CCI and mortality at 30 days, 90 days, and 1 year (P < 0.001). Mortality was higher in patients with spinal cord injury (14/108; 13%) than in those without (11/232; 5%) (P = 0.021). No association existed between ISS and mortality (P = 0.26). The CCI was associated with a higher proportion of deaths at 30 days, 90 days, and 1 year. This association may help predict this unfortunate complication and guide the surgical team in formulating treatment plans and counseling patients and families regarding mortality associated with these injuries and the risks of surgical intervention.
