Studies have shown that low serum albumin (Salb) levels are associated with a high risk of mortality among patients on maintenance hemodialysis (MHD); however, the impact of Salb variability on short-term cardiovascular mortality remains unclear. Herein, we investigated the association between Salb levels and Salb variability on short-term all-cause and cardiovascular-related mortality in patients on MHD.Eligible patients on MHD at Chongqing General Hospital between June 2017 and June 2020 were recruited in this study. Patients were grouped by Salb levels (normal Salb, ≥3.8 g/dL; low Salb, 3.4-3.8 g/dL; and lower Salb, 2-3.4 g/dL) and Salb variability (decreased, >5% loss; increased, >5% gain; and steady, 5% loss to 5% gain). Associations between Salb levels, Salb variability, and all-cause and cardiovascular-related mortality were analyzed using Cox regression models. A survival analysis was performed using the Kaplan-Meier analysis.We enrolled a total of 181 patients on MHD with an average age of 65 years (interquartile range [IQR], 53-75 years). The mean Salb level was 3.8 ± 0.6 g/dL (IQR 2.9-4.4 g/dL), and the median Salb variability was 2.6% per year (IQR, À4.1 to 6.5). Fifty-two (29%) patients died, including 31 (17%) patients who died due to cardiovascular-related causes. Compared with the other groups, the lower Salb group had higher all-cause mortality (P < .01). Cox regression analyses revealed that lower Salb levels and decreased Salb variability were independently associated with all-cause mortality (hazard ratio [HR] = 1.95, 95% confidence interval [CI] 1.103-3.452; HR = 2.245, 95% CI 1.084-4.650), whereas increased Salb variability was independently associated with cardiovascular-related mortality (HR = 2.919, 95% CI 1.178-7.234; P < .05).Lower Salb levels were an independent predictor of all-cause mortality in patients on MHD. Increased Salb variability was strongly associated with cardiovascular-related mortality in the same population, especially in the short-term and in patients with normal Salb levels. Significantly elevated Salb variability should be evaluated to reduce cardiovascular-related mortality.
Background Sepsis affects millions of people each year, and brings substantial health and economic burden to the global. Esmolol may have the potential in the treatment of sepsis and septic shock in adults. However, current evidence remains controversial. Methods We systematically searched PubMed, EMBASE and the Cochrane Central Register of Controlled Trials from their inception to September 19, 2020 for randomized controlled trials (RCTs) evaluating the efficacy of esmolol in sepsis and septic shock in adults. A random-effects meta-analysis was performed to combine effect estimates. Two investigators independently screened articles, extracted data, and assessed the quality of included studies. Results Seven RCTs were included with a total of 463 patients with sepsis and/or septic shock. Overall, compared with standard treatment, esmolol significantly decreased 28-day mortality (risk ratio [RR] 0.68, 95% confidence interval [CI] 0.52 to 0.88), and heart rate (standardized mean difference [SMD] -1.83, 95% CI -2.95 to -0.70) and troponin I (TnI) level (SMD − 0.59, 95% CI -1.02 to -0.16) at 24 hours after treatment; no significant effect was found on the length of intensive care unit stay, mean arterial pressure, central venous pressure, central venous oxygen saturation, Stroke Volume Index, tumor necrosis factor-a, interleukin 6, White Blood Cells and PO2/FiO2. Conclusions Esmolol treatment may be safe and effective in decreasing 28-day mortality, controlling heart rate, and preventing myocardial damage, but no evidence of effect on lung injury in sepsis and septic shock after fluid resuscitation early. There were no significant adverse effects on tissue perfusion and oxygen utilization.
Background: Since December 2019, COVID-19 has spread to the world which leads to a global health threat. We aimed to investigate the effectiveness of tocilizumab on COVID-19 patients.Methods: We systematically searched PubMed, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL) and WHO international Clinical Trials Registry Platform (ICTRP) from their inception to March 10, 2021 for randomized controlled trials (RCTs) on tocilizumab supplementation in adults with COVID-19 disease. The primary outcomes were mortality at 28-30 day and 60-day, incidence of mechanical ventilation (MV), composite outcome of death or MV, time to hospital discharge, and intensive care unit (ICU) admissions. A random-effects meta-analysis model was used to pool studies. Results: Eleven studies with a total of 6,579 patients were included in our meta-analysis, of which 3,406 and 3,173 were respectively assigned to the tocilizumab and control groups. Tocilizumab could significantly reduce 28-30 day mortality (RR = 0.89, 95% CI 0.80-0.99, P = 0.04), incidence of MV (RR= 0.79, 95% CI 0.71-0.89, P = 0.0001), composition outcome of MV or death (RR = 0.81, 95% CI 0.72-0.90, P = 0.0002), time to hospital discharge (HR = 1.30, 95% CI 1.16-1.45, P < 0.00001 ), ICU admissions (RR = 0.64, 95% CI 0.47-0.88, P = 0.006), serious infection (RR = 0.61, 95% CI 0.40-0.94, P = 0.02) and events of serious adverse advents (RR = 0.64, 95% CI 0.47-0.86, P = 0.004). There was no significant difference between tocilizumab and control groups in 60-day mortality and adverse events (AEs).Conclusions: Tocilizumab could reduce the short-term mortality, incidence of MV, composite outcome of death or MV, ICU admissions, serious infection and events of serious adverse advents, and shorten the time to hospital discharge in hospitalized patients with COVID-19. The optimal effective dose needs to be confirmed by further studies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
