Objective To examine all-cause mortality rates in patients with acromegaly on pegvisomant and identify pertinent risk factors, including insulin-like growth factor I (IGF-I). Design Retrospective cohort analysis of data from ACROSTUDY (global surveillance study of patients with acromegaly treated with pegvisomant). Methods Kaplan–Meier analyses and Cox regression techniques were used to examine survival rates. Standardized mortality ratios (SMR) with reference to general population (WHO GBD 2016) were estimated. Multiplicative multiple Poisson regression models were used to characterize the association between SMR, IGF-I, and other risk factors associated with mortality risk. Results The study consisted of 2077 subjects who were followed for a median interval of 4.1 years, contributing to 8957 patient-years. Higher on-treatment IGF-I (P = 0.0035), older attained age (P < 0.0001), and longer duration of acromegaly (>10 years) before starting pegvisomant (P = 0.05) were associated with higher mortality rates. In reference to general population rates, higher SMR (1.10, 1.42, and 2.62, at attained age 55 years) were observed with higher serum IGF-I category (SMR trend: 1.44 (44%)/per fold level of IGF-I/ULN (95% CI: 1.10, 1.87), P = 0.0075). SMR increased per year of younger attained age (1.04 (1.02–1.04), P < 0.0001) and were higher for longer disease duration (>10 years) before starting pegvisomant (1.57 (1.02, 2.43), P = 0.042). Serum IGF-I levels within the normal range during pegvisomant therapy were associated with all-cause mortality rates that were indistinguishable from the general population. Conclusions Higher on-treatment IGF-I, older attained age, and longer duration of acromegaly before starting pegvisomant are associated with higher all-cause mortality rates. Younger patients with uncontrolled acromegaly have higher excess all-cause mortality rates in comparison with older patients.

Abstract We investigated the predictors of delay in the diagnosis and mortality of patients with COVID-19 in Rio de Janeiro, Brazil. A cohort of 3,656 patients were evaluated (Feb-Apr 2020) and patients’ sociodemographic characteristics, and social development index (SDI) were used as determinant factors of diagnosis delays and mortality. Kaplan-Meier survival analyses, time-dependent Cox regression models, and multivariate logistic regression analyses were conducted. The median time from symptoms onset to diagnosis was eight days (interquartile range [IQR] 7.23-8.99 days). Half of the patients recovered during the evaluated period, and 8.3% died. Mortality rates were higher in men. Delays in diagnosis were associated with male gender (p = 0.015) and patients living in low SDI areas (p < 0.001). The age groups statistically associated with death were: 70-79 years, 80-89 years, and 90-99 years. Delays to diagnosis greater than eight days were also risk factors for death. Delays in diagnosis and risk factors for death from COVID-19 were associated with male gender, age under 60 years, and patients living in regions with lower SDI. Delays superior to eight days to diagnosis increased mortality rates.

Abstract Background Three-dimensional echocardiography (3DE) may have advantages over two-dimensional echocardiography (2DE) for the assessment of left ventricular (LV) function and structure. However, studies comparing 3DE and 2DE-derived indices in relation to mortality are limited, particularly in the general population. Purpose We examined associations between 2DE and 3DE-derived LV ejection fractions (LVEF) and volumes for all-cause mortality in a population-based sample. Methods A total of 899 individuals (age, 69.6±6.1 years; 77.5%male) from the SABRE study, a UK-based tri-ethnic community cohort, underwent a comprehensive transthoracic echocardiography examination. 2D LVEF and volumes were calculated, and full-volume 3D LV datasets acquired over 4 sub-volumes were obtained using a matrix-array transducer and were analysed offline using Qlab advanced, v7.0. The associations between both 2D- and 3D-derived LVEF (≥55% vs. <55%), body surface area indexed end-diastolic volume (iEDV) and end-systolic volume (iESV), and all-cause mortality were determined using Cox proportional hazards models. Survival curves were constructed using the Kaplan-Meier method. Results Of the 899 individuals, 118 (13.1%) died over a median follow-up period of 8 years to 2018. Kaplan Meier survival estimates (Figure 1 illustrates LVEF) and Cox regression revealed that 2D and 3D LVEF, iEDV and iESV were associated with increased risk of all-cause mortality (LVEF (≥55% vs. <55%), 3DE: HR=0.53 (0.35, 0.80); 2DE: HR=0.51 (0.34, 0.75), iEDV (per 1SD increment), 3DE: HR=1.20 (1.0, 1.41); 2DE: HR=1.19 (1.0–1.41), iESV (per 1SD increment), 3DE: HR=1.27 (1.1, 1.52), 2DE: HR=1.32 (1.15, 0.1.51)). However, 3DE associations tended to be stronger in models adjusted for classical risk factors including age, sex, ethnicity, systolic blood pressure, cholesterol:HDL ratio, body mass index, antihypertensive medications, diabetes, and smoking (LVEF (≥55% vs. <55%), 3DE: HR=0.59 (0.39, 0.90); 2DE: HR=0.69 (0.46, 1.0), iEDV (per 1SD increment), 3DE: HR=1.20 (1.0, 1.41); 2DE: HR=1.10 (0.93, 1.31), iESV (per 1SD increment), 3DE: HR=1.27 (1.1, 1.52), 2DE: HR=1.20 (1.04, 0.1.39)). Figure 1. Kaplan-Meier curves. Conclusions In this population-based study, both 2DE and 3DE-derived indices of LV structure and function were associated with all-cause mortality independently of classical risk factors, with some indication that strengths of association were greater for 3DE-derived indices.

Abstract Background: There are limited data on the association of diabetes mellitus (DM) and levels of glycated hemoglobin (HbA1c) with outcomes in patients with atrial fibrillation (AF).Methods: This retrospective cohort study included patients who were recently hospitalized with a primary or secondary diagnosis of AF from December 2015 through June 2018. Kaplan-Meier curves and Cox-regression adjusted hazard ratios (aHR) were calculated for the primary outcome of all-cause mortality and for the secondary outcomes of cardiovascular (CV) mortality, stroke and the composite outcome of CV death or hospitalization. Spline curve models were fitted to investigate associations of HbA1c values and mortality among patients with AF and DM.Results: In total 1140 AF patients were included, of whom 373 (32.7%) had DM. During a median follow-up of 2.6 years, 414 (37.3%) patients died. The presence of DM was associated with a higher risk of all-cause mortality (aHR=1.44, 95% confidence intervals [CI]: 1.12-1.85), CV mortality (aHR=1.44, 95% CI: 1.08-1.93), stroke (aHR=2.62, 95% CI: 1.24-5.53) and the composite outcome of hospitalization or CV death (aHR=1.28, 95% CI: 1.06-1.54). In AF patients with comorbid DM, the spline curves showed a positive linear association between HbA1c levels and outcomes, with values 7.6-8.2% being independent predictors of increased all-cause mortality, and values <6.2% predicting significantly decreased all-cause and CV mortality.Conclusions: The presence of DM on top of AF was associated with a 1.5-fold increased risk for all-cause or CV mortality and excess morbidity. HbA1c levels lower than 6.2% were independently related to better survival rates.

ObjectivesTo compare current all-cause mortality rates in rheumatoid arthritis (RA), ankylosing spondylitis (AS), psoriatic arthritis (PsA), systemic lupus erythematosus (SLE) and systemic sclerosis (SSc) versus general population.MethodsIn this population-based, retrospective cohort study, anonymised data on 11 186 586 citizens, including all patients with RA (42 735, 79% female), AS (9707, 43% female), PsA (13 779, 55% female), SLE (10 440, 89% female) and SSc (2277, 88% female), (median age of 64/47/54/53/59 years at study entry, respectively), under prescribed treatment between 2015 and 2019, were extracted from the electronic database covering nearly 99% of the Greek population.ResultsAfter 1:5 (patients:general population) matching for gender/age, we found that survival was worse in SSc, followed by SLE and inflammatory arthritis. Compared with the general population HRs for death increased from the first 3 years to 5 years of observation possibly due to increases in disease duration: RA (from 0.63 to 1.13 (95% CI: 1.05 to 1.22), AS (from 0.62 to 1.01, (95% CI: 0.76 to 1.33)), PsA (from 0.68 to 1.06, (95% CI: 0.88 to 1.28)), SLE (from 1.52 to 1.98, (95% CI: 1.67 to 2.33)) and SSc (from 2.27 to 4.24, (95% CI: 3.19 to 5.63)). In both SLE and SSc mortality was increased in men than women and in patients younger than 50 years.ConclusionsSurvival rates over 5 years in inflammatory arthritis under treatment are currently becoming comparable (AS/PsA) or slightly higher (RA) than those of the general population. However, all-cause mortality is almost twofold and fourfold higher in SLE and SSc, respectively, being even higher for male and younger patients.

ObjectiveLittle is known about the impact of low triiodothyronine (T3) levels on mortality in end-stage renal disease (ESRD) patients starting hemodialysis (HD) and whether this impact is mediated by malnutrition, inflammation, or cardiac dysfunction.Design and methodsA prospective cohort of 471 incident HD patients from 36 dialysis centers within the Clinical Research Center for ESRD in Korea was selected for this study. Based on the median value of T3, patients were divided into ‘higher’ and ‘lower’ groups, and all-cause and cardiovascular (CV) mortality rates were compared. In addition, associations between T3levels and various nutritional, inflammatory, and echocardiographic parameters were determined.ResultsCompared with those in the ‘higher’ T3group, albumin, cholesterol, and triglyceride levels, lean body mass estimated by creatinine kinetics (LBM-Cr), and normalized protein catabolic rate (nPCR) were significantly lower in patients with ‘lower’ T3levels. The ‘lower’ T3group also had a higher left ventricular mass index (LVMI) and a lower ejection fraction (EF). Furthermore, correlation analysis revealed significant associations between T3levels and nutritional and echocardiographic parameters. All-cause and CV mortality rates were significantly higher in patients with ‘lower’ T3levels than in the ‘higher’ T3group (113.4 vs 18.2 events per 1000 patient-years,P<0.001, and 49.8 vs 9.1 events per 1000 patient-years,P=0.001, respectively). The Kaplan–Meier analysis also showed significantly worse cumulative survival rates in the ‘lower’ T3group (P<0.001). In the Cox regression analysis, low T3was an independent predictor of all-cause mortality even after adjusting for traditional risk factors (hazard ratio=3.76,P=0.021). However, the significant impact of low T3on all-cause mortality disappeared when LBM-Cr, nPCR, LVMI, or EF were incorporated into the models.ConclusionLow T3has an impact on all-cause mortality in incident HD patients, partly via malnutrition and cardiac dysfunction.

Abstract Background: Carbapenem-resistant Klebsiella pneumoniae bloodstream infections (CRKP-BSIs) are associated with high morbidity and mortality rates, especially in critically ill patients. Comprehensive mortality risk analyses and therapeutic assessment in real-world practice are beneficial to guide individual treatment.Methods: We retrospectively analyzed 87 patients with CRKP-BSIs (between July 2016 and June 2020) to identify the independent risk factors for 28-day all-cause mortality. The therapeutic efficacies of tigecycline-and polymyxin B-based therapies were analyzed.Results: The 28-day all-cause mortality and in-hospital mortality rates were 52.87% and 67.82%, respectively, arising predominantly from intra-abdominal (56.32%) and respiratory tract infections (21.84%). A multivariate analysis showed that 28-day all-cause mortality was independently associated with the patient’s APACHE II score (p = 0.002) and presence of septic shock at BSI onset (p = 0.006). All-cause mortality was not significantly different between patients receiving tigecycline- or polymyxin B-based therapy (55.81% vs. 53.85%, p = 0.873), and between subgroups mortality rates were also similar. Conclusions: Critical illness indicators (APACHE II scores and presence of septic shock at BSI onset) were independent risk factors for 28-day all-cause mortality. There was no significant difference between tigecycline- and polymyxin B-based therapy outcomes. Prompt and appropriate infection control should be implemented to prevent CRKP infections.

Abstract Background : To investigate whether there is a distinct difference in prognosis between hepatoid adenocarcinoma of the stomach ( HAS) and non-hepatoid adenocarcinoma of the stomach (non-HAS) and whether HAS can benefit from radical surgery. Methods : We retrospectively reviewed 722 patients with non-HAS and 75 patients with HAS who underwent radical gastrectomy between 3 November 2009 and 17 December 2018. Propensity score matching (PSM) analysis was used to eliminate the bias among the patients in our study. The relationships between gastric cancer type and overall survival (OS) were evaluated by the Kaplan-Meier method and Cox regression. Results : Our data demonstrate that there was no statistically significant difference in the OS between HAS and non-HAS {K-M, P=log rank (Mantel-Cox), (before PSM P=0.397); (1:1 PSM P=0.345); (1:2 PSM P=0.195)}. Moreover, there were no significant differences in the 1-, 2-, or 3-year survival rates between patients with non-HAS and patients with HAS (before propensity matching, after 1:1 propensity matching, and after 1:2 propensity matching). Conclusion : HAS was generally considered to be an aggressive gastric neoplasm, but its prognosis may not be as unsatisfactory as previously believed.

Abstract Background: The benefits of surgical resection (SR) for various Barcelona Clinic Liver Cancer (BCLC) stages of hepatocellular carcinoma (HCC) remain unclear. We investigated the risk factors of overall survival (OS) and survival benefits of SR over nonsurgical treatments in patients with HCC of various BCLC stages.Methods: Overall, 2316 HCC patients were included, and their clinicopathological data and OS were recorded. OS was analyzed by the Kaplan-Meier method and Cox regression analysis. Propensity score matching (PSM) analysis was performed.Results: In total, 66 (2.8%), 865 (37.4%), 575 (24.8%) and 870 (35.0%) patients had BCLC stage 0, A, B, and C disease, respectively. Furthermore, 1302 (56.2%) of all patients, and 37 (56.9%), 472 (54.6%), 313 (54.4%) and 480 (59.3%) of patients with BCLC stage 0, A, B, and C disease, respectively, died. The median follow-up duration time was 20 (range 0-96) months for the total cohort and was subdivided into 52 (8-96), 32 (1-96), 19 (0-84), and 12 (0-79) months for BCLC stages 0, A, B, and C cohorts, respectively. The risk factors for OS were 1) SR and cirrhosis; 2) SR, cirrhosis, and Child-Pugh (C-P) class; 3) SR, hepatitis B virus (HBV) infection, and C-P class; and 4) SR, HBV infection, and C-P class for the BCLC stage 0, A, B, and C cohorts, respectively. Compared to non-SR treatment, SR resulted in significantly higher survival rates in all cohorts. The 5-year OS rates for SR vs non-SR were 44.0% vs 28.7%, 72.2% vs 42.6%, 42.6% vs 36.2, 44.6% vs 23.5%, and 41.4% vs 15.3% (all p-values<0.05) in the total and BCLC stage 0, A, B, and C cohorts, respectively. After PSM, SR resulted in significantly higher survival rates compared to non-SR treatment in various BCLC stages.Conclusion: SR conferred significant survival benefits to patients with HCC of various BCLC stages and should be considered a recommended treatment for select HCC patients, especially patients with BCLC stage B and C disease.

Osteosarcoma (OS) often occurs in children and often undergoes metastasis, resulting in lower survival rates. Information on the complexity and pathogenic mechanism of OS is limited, and thus, the development of treatments involving alternative molecular and genetic targets is hampered. We categorized transcriptome data into metastasis and nonmetastasis groups, and 400 differential RNAs (230 messenger RNAs (mRNAs) and 170 long noncoding RNAs (lncRNAs)) were obtained by the edgeR package. Prognostic genes were identified by performing univariate Cox regression analysis and the Kaplan–Meier (KM) survival analysis. We then examined the correlation between the expression level of prognostic lncRNAs and mRNAs. Furthermore, microRNAs (miRNAs) corresponding to the coexpression of lncRNA-mRNA was predicted, which was used to construct a competitive endogenous RNA (ceRNA) regulatory network. Finally, multivariate Cox proportional risk regression analysis was used to identify hub prognostic genes. Three hub prognostic genes (ABCG8, LOXL4, and PDE1B) were identified as potential prognostic biomarkers and therapeutic targets for OS. Furthermore, transcriptions factors (TFs) (DBP, ESX1, FOS, FOXI1, MEF2C, NFE2, and OTX2) and lncRNAs (RP11-357H14.16, RP11-284N8.3, and RP11-629G13.1) that were able to affect the expression levels of genes before and after transcription were found to regulate the prognostic hub genes. In addition, we identified drugs related to the prognostic hub genes, which may have potential clinical applications. Immunohistochemistry (IHC) and quantitative real-time polymerase chain reaction (qRT-PCR) confirmed that the expression levels of ABCG8, LOXL4, and PDE1B coincided with the results of bioinformatics analysis. Moreover, the relationship between the hub prognostic gene expression and patient prognosis was also validated. Our study elucidated the roles of three novel prognostic biomarkers in the pathogenesis of OS as well as presenting a potential clinical treatment for OS.

Abstract Background Nonalcoholic fatty liver disease (NAFLD) is a hepatic manifestation of metabolic disease and independently affects the development of cardiovascular (CV) disease. We investigated whether hepatic steatosis and/or fibrosis are associated with the development of incident heart failure (iHF), hospitalized HF (hHF), mortality, and CV death in both the general population and HF patients. Methods We analyzed 778,739 individuals without HF and 7445 patients with pre-existing HF aged 40 to 80 years who underwent a national health check-up from January 2009 to December 2012. The presence of hepatic steatosis and advanced hepatic fibrosis was determined using cutoff values for fatty liver index (FLI) and BARD score. We evaluated the association of FLI or BARD score with the development of iHF, hHF, mortality and CV death using multivariable-adjusted Cox regression models. Results A total of 28,524 (3.7%) individuals in the general population and 1422 (19.1%) pre-existing HF patients developed iHF and hHF respectively. In the multivariable-adjusted model, participants with an FLI ≥ 60 were at increased risk for iHF (hazard ratio [HR], 95% confidence interval [CI], 1.30, 1.24–1.36), hHF (HR 1.54, 95% CI 1.44–1.66), all-cause mortality (HR 1.62, 95% CI 1.54–1.70), and CV mortality (HR 1.41 95% CI 1.22–1.63) in the general population and hHF (HR 1.26, 95% CI 1.21–1.54) and all-cause mortality (HR 1.54 95% CI 1.24–1.92) in the HF patient group compared with an FLI < 20. Among participants with NAFLD, advanced liver fibrosis was associated with increased risk for iHF, hHF, and all-cause mortality in the general population and all-cause mortality and CV mortality in the HF patient group (all p < 0.05). Conclusion Hepatic steatosis and/or advanced fibrosis as assessed by FLI and BARD score was significantly associated with the risk of HF and mortality.
