Background: D-dimer is a small protein fragment and high levels of D-dimer have been associated with increased mortality in patients presenting to emergency departments with infection. Previous studies have reported increased levels of D-dimer in COVID-19; however, it is unclear whether an increased D-dimer level provides early warning of poor prognosis. Therefore, this study aimed to assess the usefulness of D-dimer as an early indicator of prognosis in patients with coronavirus disease (COVID-19).Methods: We conducted a retrospective study of patients with COVID-19 admitted to Leishenshan Hospital in Wuhan, China, from February 15 to March 30, 2020. The final date of follow-up was April 11, 2020.Results: Of the 1,643 patients with COVID-19, 691 had elevated D-dimer levels. Their median age was 65 years. Of the patients with elevated D-dimer levels, 45% had comorbidities, with cardiovascular disease (205 [29.7%]) being the most common. Patients with elevated D-dimer were more likely to require treatment with high-flow oxygen, anticoagulation, antibiotics, and admission to the intensive care unit They were also more likely to have increased interleukin-6, monocytes, and lymphocytes. Patients with elevated D-dimer levels had significantly higher mortality than those with normal or low D-dimer levels.Conclusion: In patients with COVID-19, elevated D-dimer was associated with abnormal immunity, underlying disease, increased disease severity, and increased mortality. Taken together, D-dimer may be a marker for the early warning of disease severity and increased risk of death. These findings provide insights into the potential risk of elevated D-dimer in patients with COVID-19.

Objective. To assess the association between D-dimer and clinical outcomes in adults with COVID-19. Methods. We reviewed published articles and preprints from MEDLINE, Cochrane Library, Cornell Open Access Publication (COAP), MedRxiv, and BioRxiv databases. We included cohort studies on the association between D-dimer and the outcomes of thromboembolism, mortality, and worsening severity among hospitalized adults with COVID-19. Results. We found 25 observational studies on the association between D-dimer and the outcomes of thromboembolism, mortality, or worsening severity. There was an increased risk of thromboembolism (OR 5.61 [95% CI 3.97, 7.94]) with higher D-dimer levels across different COVID-19 severities. D-dimer levels are associated with higher in-hospital mortality (OR 5.57 [95% CI 2.74, 11.31]) and worsening severity manifesting as critical illness (OR 1.91 [95% CI 1.05, 3.48] to 2.58 [95% CI 1.57, 4.24]), disease progression (HR 2.846 [95% CI 2.10, 3.85]), or need for mechanical ventilation (HR 3.28 [95% CI 1.07, 10.10]). However, some methodological flaws, such as incomplete laboratory or follow-up data and concern on varied D-dimer cut-offs and definitions of worsening disease, raise some uncertainty in the widespread use of D-dimer as a prognostic marker. Conclusion. A higher D-dimer value is associated with worse clinical outcomes among hospitalized adults with COVID-19 and may be a useful prognostic indicator.

ObjectiveD-dimer might serve as a marker of thrombogenesis and a hypercoagulable state following plaque rupture. Few studies explore the association between baseline D-dimer levels and the incidence of heart failure (HF), all-cause mortality in an acute myocardial infarction (AMI) population. We aimed to explore this association.MethodsWe enrolled 4504 consecutive patients with AMI with complete data in a prospective cohort study and explored the association of plasma D-dimer levels on admission and the incidence of HF, all-cause mortality.ResultsOver a median follow-up of 1 year, 1112 (24.7%) patients developed in-hospital HF, 542 (16.7%) patients developed HF after hospitalisation and 233 (7.1%) patients died. After full adjustments for other relevant clinical covariates, patients with D-dimer values in quartile 3 (Q3) had 1.51 times (95% CI 1.12 to 2.04) and in Q4 had 1.49 times (95% CI 1.09 to 2.04) as high as the risk of HF after hospitalisation compared with patients in Q1. Patients with D-dimer values in Q4 had more than a twofold (HR 2.34; 95% CI 1.33 to 4.13) increased risk of death compared with patients in Q1 (p<0.001). But there was no association between D-dimer levels and in-hospital HF in the adjusted models.ConclusionsD-dimer was found to be associated with the incidence of HF after hospitalisation and all-cause mortality in patients with AMI.

Abstract Background Perceived physical fatigability is highly prevalent in older adults and associated with mobility decline and other health consequences. We examined the prognostic value of perceived physical fatigability as an independent predictor of risk of death among older adults. Methods Participants (N = 2,906), mean age 73.5 [SD, 10.4] years, 54.2% women, 99.7% white enrolled in the Long Life Family Study were assessed at Visit 2 (2014-2017) with 2.7 [SD, 1.0] years follow-up. The Pittsburgh Fatigability Scale (PFS), a 10-item, self-administered validated questionnaire (score range 0-50, higher=greater fatigability) measured perceived physical fatigability at Visit 2. Deaths post-Visit 2 through December 31, 2019 were identified by: family members notifying field centers, reporting during another family member’s annual phone follow-up, an obituary, or Civil Registration System (Denmark). We censored all other participants at their last contact. Cox proportional hazard models predicted mortality by fatigability severity, adjusted for family relatedness and other covariates. Results Age-adjusted PFS Physical scores were higher for those who died (19.1 [SE, 0.8]) compared to alive (12.2, [SE, 0.4]) overall, as well as across age strata (P&lt;.001), except for those 60-69 years (P=.79). Participants with the most severe fatigability (PFS Physical scores ≥25) were over twice as likely to die (HR, 2.33 [95% CI, 1.65 to 3.28]) compared to those with less severe fatigability (PFS Physical scores &lt;25) after adjustment. Conclusions This work underscores the utility of the PFS as a novel patient-reported prognostic indicator of phenotypic aging that captures both overt and underlying disease burden that predicts death.

Abstract Background In the Tafamidis in Transthyretin Cardiomyopathy Clinical Trial (ATTR-ACT), tafamidis was shown to be an effective treatment for patients with transthyretin amyloid cardiomyopathy (ATTR-CM). Further assessment of the efficacy of tafamidis in patients with more advanced ATTR-CM would aid treatment decisions. Purpose To characterize the benefits of tafamidis in patients with advanced ATTR-CM. Methods In ATTR-ACT, ATTR-CM patients were randomized to tafamidis (n=264) or placebo (n=177) for 30 months. Efficacy outcomes included all-cause mortality and frequency of cardiovascular (CV)-related hospitalisations. Key secondary endpoints were change from baseline to Month 30 in 6MWT distance and KCCQ-OS score. Efficacy assessments in NYHA Class III patients at baseline (n=141) were a pre-specified analysis. In a post-hoc analysis, mortality and CV-related hospitalizations were assessed in all patients grouped into quartiles of increasing disease severity based on 6MWT distance at baseline. Longer-term all-cause mortality (as of 1 Aug 2019) was assessed in NYHA Class III patients utilizing data from ATTR-ACT patients who enrolled in a long-term, extension study (LTE) and continued treatment with higher dose tafamidis (n=55; median treatment duration 51.6 months); or, if previously treated with placebo, started tafamidis treatment (placebo/tafamidis; n=63 [50.1 months]). Results In advanced ATTR-CM patients (NYHA Class III), tafamidis reduced the risk of death (HR [95% CI] 0.837, [0.541, 1.295], P=0.4253), and the decline in 6MWT distance (LS mean [SE], 31.6 (22.1) m; P=0.1526) and KCCQ-OS score (LS mean [SE], 13.1 (5.0); P=0.0090), vs placebo. Paradoxically, there was a higher frequency of CV-related hospitalizations with tafamidis (RR [95% CI] vs placebo, 1.411 [1.048, 1.900]). In all patients by 6MWT quartile, CV-related hospitalizations/year with tafamidis and placebo increased with disease severity, with the exception that placebo-treated patients in the highest severity quartile had fewer CV-related hospitalisations (0.73) than those in the third quartile (0.92). Mortality with tafamidis and placebo increased, and was greater with placebo, in every quartile (Figure). Survival (NYHA Class III patients in ATTR-ACT and LTE) was improved with high dose tafamidis with longer term follow-up (HR vs placebo/tafamidis [95% CI], 0.6569 [0.4175, 1.0336]; P=0.0692). Conclusions These analyses, including longer-term follow-up, demonstrate that patients with advanced ATTR-CM benefit from tafamidis. The decrease in CV-related hospitalisations in more severe patients treated with placebo suggests that the comparatively greater hospitalisation frequency in NYHA Class III patients treated with tafamidis is a consequence of their lower mortality rate.

Abstract Background Associations between D-dimer and outcomes of patients with acute coronary syndromes (ACS) remain controversial. This study aimed to investigate the prognostic value of D-dimer in ACS patients treated by percutaneous coronary intervention (PCI). Methods In this observational study, 3972 consecutive patients with ACS treated by PCI were retrospectively recruited. The X-tile program was used to determine the optimal D-dimer thresholds for risk stratifications. Cox regression with multiple adjustments was used for outcome analysis. Restricted cubic spline (RCS) analysis was performed to assess the dose-response association between D-dimer and outcomes. The C-index was calculated to evaluate the additional prognostic value of D-dimer when added to clinical risk factors and commonly used clinical risk scores, with internal validations using bootstrapping methods. The primary outcome was all-cause death. Results During a median follow-up of 720 days, 225 deaths occurred. Based on the thresholds generated by X-tile, ACS-PCI patients with median (420–1150 ng/mL, hazard ratio [HR]: 1.58, 95 % confidence interval [CI]: 1.14–2.20, P = 0.007) and high (≥ 1150 ng/mL, HR: 1.98, 95 % CI: 1.36–2.89, P < 0.001) levels of D-dimer showed substantially higher risk of death compared to those with low D-dimer (< 420 ng/mL). RCS analysis depicted a constant relation between D-dimer and various outcomes. The addition of D-dimer levels significantly improved risk predictions for all-cause death when combined with the fully adjusted models (C-index: 0.853 vs. 0.845, P difference = 0.021), the GRACE score (C-index: 0.826 vs. 0.814, P difference = 0.027), and the TIMI score (C-index: 0.804 vs. 0.776, P difference < 0.001). The predicted mortality at the median follow-up (two years) was 1.7 %, 5.2 %, and 10.9 % for patients with low, median, and high D-dimer, respectively, which was well matched with the observed mortality (low D-dimer group: 1.2 %, median D-dimer group: 5.2 %, and high D-dimer group: 12.6 %). Conclusions For ACS patients treated by PCI, D-dimer level was an independent predictor for adverse outcomes, and provided additional prognostic value when combined with clinical risk factors and risk scores. Risk stratifications based on D-dimer was plausible to differentiate ACS-PCI patients with higher risk of death.

AbstractTakotsubo syndrome (TTS) is an acute heart failure syndrome with significant rates of in and out-of-hospital mayor cardiac adverse events (MACE). To evaluate the possible role of neoplastic biomarkers [CA-15.3, CA-19.9 and Carcinoembryonic Antigen (CEA)] as prognostic marker at short- and long-term follow-up in subjects with TTS. Ninety consecutive subjects with TTS were enrolled and followed for a median of 3 years. Circulating levels of CA-15.3, CA-19.9 and CEA were evaluated at admission, after 72 h and at discharge. Incidence of MACE during hospitalization and follow-up were recorded. Forty-three (46%) patients experienced MACE during hospitalization. These patients had increased admission levels of CEA (4.3 ± 6.2 vs. 2.2 ± 1.5 ng/mL, p = 0.03). CEA levels were higher in subjects with in-hospital MACE. At long term follow-up, CEA and CA-19.9 levels were associated with increased risk of death (log rank p < 0.01, HR = 5.3, 95% CI 1.9–14.8, HR = 7.8 95% CI 2.4–25.1, respectively, p < 0.01). At multivariable analysis levels higher than median of CEA, CA-19.9 or both were independent predictors of death at long term (Log-Rank p < 0.01). Having both CEA and CA-19.9 levels above median (> 2 ng/mL, > 8 UI/mL respectively) was associated with an increased risk of mortality of 11.8 (95% CI 2.6–52.5, p = 0.001) at follow up. Increased CEA and CA-19.9 serum levels are associated with higher risk of death at long-term follow up in patients with TTS. CEA serum levels are correlated with in-hospital MACE.

The prevalence of idiopathic pulmonary fibrosis (IPF), a fatal and progressive lung disease, is estimated at 1.25–63 out of 100 000, making large population studies difficult. Recently, the need for large longitudinal registries to study IPF has been recognised.The Australian IPF Registry (AIPFR) is a national registry collating comprehensive longitudinal data of IPF patients across Australia. We explored the characteristics of this IPF cohort and the effect of demographic and physiological parameters and specific management on mortality.Participants in the AIPFR (n=647, mean age 70.9±8.5 years, 67.7% male, median follow up 2 years, range 6 months–4.5 years) displayed a wide range of age, disease severity and co-morbidities that is not present in clinical trial cohorts. The cumulative mortality rate in year one, two, three and four was 5%, 24%, 37% and 44% respectively. Baseline lung function (forced vital capacity, diffusing capacity of the lung for carbon monoxide, composite physiological index) and GAP (gender, age, physiology) stage (hazard ratio 4.64, 95% CI 3.33–6.47, p<0.001) were strong predictors of mortality. Patients receiving anti-fibrotic medications had better survival (hazard ratio 0.56, 95% CI 0.34–0.92, p=0.022) than those not on anti-fibrotic medications, independent of underlying disease severity.The AIPFR provides important insights into the understanding of the natural history and clinical management of IPF.

The identification of new SARS-CoV-2 and human protein and gene targets, which may be markers of the severity and outcome of the disease, are extremely important during the COVID-19 pandemic. The goal of this study was to carry out genetic analysis of SARS-CoV-2 RNA samples to elucidate correlations of genetic parameters (SNPs) with clinical data and severity of COVID-19 infection.Material and Methods. The study included viral RNA samples isolated from 56 patients with COVID-19 infection who received treatment at the City Hospital No. 40 of St. Petersburg from 04/18/2020 to 04/18/2021. Patients underwent physical examination with the assessments of hemodynamic and respiratory parameters, clinical risk according to National Early Warning Score (NEWS), computed tomography (CT) of the chest, and laboratory studies including clinical blood analysis, assessment of ferritin, C-reactive protein (CRP), interleukin-6 (IL-6), lactate dehydrogenase (LDH), D-dimer, creatinine, and glucose levels. All patients tested positive for SARS-CoV-2 RNA by polymerase chain reaction (PCR). Single nucleotide polymorphisms (SNPs) in viral RNA were identified through the creation of cDNA libraries by targeted sequencing (MiSeq Illumina). Bioinformatic analysis of viral samples was performed using the viralrecon v2 pipeline with the further annotation via Pangolin and Nextlade. Sampled genomes were visualized using the Integrative Genomics Viewer (IGV) software. Statistical data processing (descriptive statistics and graphical analysis of data relationships from diff erent tables) was performed using a GraphPad device on the Prism 8.01 platform.Results. A comparative analysis of SNP frequencies in the virus genome in samples from deceased and discharged patients was carried out. The SNPs associated with risk of death (OR > 1), neutral SNPs (OR = 1), and protective SNPs (OR < 1) were identifi ed. Patient samples were infected with 14 lines of SARS-CoV-2, fi ve of which (B.1.1.129, B.1.1.407, B.1.1.373, B.1.1.397, and B.1.1.152) were of Russian origin. The SNPs in the samples infected with the strains of non-Russian origin were associated with an increased risk of mortality (OR = 2.267, 95% confi dence interval 0.1594-8.653) compared to the SNPs in the samples obtained from the group of patients infected with the strains of Russian origin. Positive correlations were identifi ed between the average SNP number, nonsynonymous SNPs, and S-protein SNPs with the degree of respiratory failure, total NEWS score, CT-based form of disease, duration of treatment with mechanical ventilation, disease outcome, levels of LDH, glucose, D-dimer, and ferritin, and RNA amount in the PCR test. S-protein SNPs negatively correlated with the leukocyte and neutrophil counts.

Background: The implications of venous thromboembolism (VTE) for morbidity and mortality in kidney transplant recipients are not well described. Methods: We conducted a retrospective study using linked healthcare databases in Ontario, Canada to determine the risk and complications of VTE in kidney transplant recipients from 2003 to 2013. We compared the incidence rate of VTE in recipients (n = 4,343) and a matched (1:4) sample of the general population (n = 17,372). For recipients with evidence of a VTE posttransplant, we compared adverse clinical outcomes (death, graft loss) to matched (1:2) recipients without evidence of a VTE posttransplant. Results: During a median follow-up of 5.2 years, 388 (8.9%) recipients developed a VTE compared to 254 (1.5%) in the matched general population (16.3 vs. 2.4 events per 1,000 person-years; hazard ratio [HR] 7.1, 95% CI 6.0-8.4; p < 0.0001). Recipients who experienced a posttransplant VTE had a higher risk of death (28.5 vs. 11.2%; HR 4.1, 95% CI 2.9-5.8; p < 0.0001) and death-censored graft loss (13.1 vs. 7.5%; HR 2.3, 95% CI 1.4-3.6; p = 0.0006) compared to matched recipients who did not experience a posttransplant VTE. Conclusions: Kidney transplant recipients have a sevenfold higher risk of VTE compared to the general population with VTE conferring an increased risk of death and graft loss.

e23540 Background: Early presentation of soft-tissue sarcoma (STS) patients to a specialized sarcoma center including discussion in the interdisciplinary sarcoma board (ISB) prior to surgery is essential to the treatment of sarcomas. This approach significantly improves patient survival and guideline coherence. However, there exists only limited information on the adherence to the recommendations of the ISB. Accordingly, we decided to analyze a STS cohort at a large German sarcoma center focusing on outcome parameters and adherence to quality parameters defined by the German Cancer Society (Deutsche Krebsgesellschaft). Methods: In a retrospective data analysis, we identified n = 230 adult patients presented at the ISB of the Charité–Universitätsmedizin Berlin in Germany from January 2015 until December 2019. Inclusion criteria were as follows: newly diagnosed STS, presentation during first-line therapy and recommendation of at least one treatment modality such as surgery, chemotherapy, radiotherapy, regional hyperthermia or follow-up by the ISB. Clinical and follow up data was collected by using the hospital information system and the outpatient network. Results: Our patient cohort included 53% male and 47% female patients with a median age of 58 years (range 19-96). The majority (86%) showed a localized tumor stage, while 14% already had metastases. In 24% of the cases the sarcomas were classified as low-grade, in 76% as high-grade. Surgery was recommended for 66% of the cases, for 80% of them combined with chemotherapy, radiotherapy or hyperthermia. 14% of the patients received a recommendation for all 4 modalities. For 9% of the patients, chemotherapy alone was recommended. Both overall survival and progression-free survival was significantly higher in the group with complete adherence to the recommendations of the ISB (p < 0.001). The worst prognosis was found in patients unable to adhere to the recommendations due to rapid progression or complications of the therapy (HR for death 15.06, 95%CI 7.94-32.22). If one recommended modality was not carried out, there also was a higher risk of death (HR 4.38, 95%CI 1.75-10.96). Most common reasons were patient refusal or individual decision by the treating physician. A metastasized tumor stage was associated with an increased risk of death (HR 2.62, 95%CI 1.45-4.75). In contrast, neither the histological grading (low vs. high) nor age did influence the mortality significantly. Conclusions: In our cohort of STS patients, survival depends significantly on adherence to the recommendations of the ISB. Our analysis at a German sarcoma center is in line with previous international reports demonstrating the importance of interdisciplinary decisions and therapeutic adherence. We hereby underline the essential role of interdisciplinary approaches in care of STS patients and the effort to implement defined quality parameters.
