Objective To investigate the causal relationships between various circulating micronutrients and aneurysms at different sites using Mendelian randomization (MR) analysis. Methods Summary-level genetic data for 15 common blood micronutrients, including vitamin D, calcium, iron, copper, selenium, zinc, folate, carotene, vitamin C, vitamin B12, vitamin E, magnesium, vitamin B6, omega-3 fatty acids, and homocysteine, were obtained from the IEU Open GWAS database. Genetic associations with aneurysms, including intracranial aneurysm and thoracic aortic aneurysm, were retrieved from the GWAS Catalog and the FinnGen consortium. Bidirectional MR analyses were performed using seven MR approaches, with the inverse-variance weighted (IVW) method as the primary analysis. Multiple sensitivity analyses and visualization tools were used to assess pleiotropy and heterogeneity. Furthermore, multivariable MR was applied to explore the interactions and independent effects of multiple micronutrients on aneurysm risk, and meta-analysis was employed to integrate results from different data sources and minimize bias. Results Through multiple MR and sensitivity analyses, combined with multivariate MR and meta-analysis, the results confirmed that elevated blood levels of vitamin D could significantly increase the risk of intracranial aneurysm [odds ratio (OR)=1.65, 95% confidence interval (CI) (1.20, 2.29), P=0.002], while omega-3 fatty acids [OR=0.82, 95%CI (0.73, 0.92), P=0.001] could significantly reduce the risk. For thoracic aortic aneurysm, selenium [OR=1.08, 95%CI (1.00, 1.15), P=0.042] and folate [OR=1.45, 95%CI (1.13, 1.87), P=0.004] were identified as potential risk factors. No heterogeneity or horizontal pleiotropy was detected, and no reverse causality was found between micronutrients and aneurysm development. Conclusions Variations in circulating micronutrient levels can influence the risk of aneurysm development. These findings provide new insights into the potential roles of micronutrients in aneurysm prevention and treatment and offer a scientific basis for developing targeted clinical intervention strategies.
Objective To investigate the relationship between thrombocytopenia after the restoration of spontaneous circulation and short-term prognosis of patients with in-hospital cardiac arrest. Methods The demographic data, post-resuscitation vital signs, post-resuscitation laboratory tests, and the 28-day mortality rate of patients who experienced in-hospital cardiac arrest at the Emergency Department of West China Hospital, Sichuan University between January 1st, 2016 and December 31st, 2016 were retrospectively analyzed. Logistic regression was used to analyze the correlation between thrombocytopenia after the return of spontaneous circulation and the 28-day mortality rate in these cardiac arrest patients. Results Among the 285 patients included, compared with the normal platelet group (n=130), the thrombocytopenia group (n=155) showed statistically significant differences in red blood cell count, hematocrit, white blood cell count, prothrombin time, activated partial thromboplastin time, and international normalized ratio (P<0.05). The 28-day mortality rate was higher in the thrombocytopenia group than that in the normal platelet group (84.5% vs. 71.5%, P=0.008). Multiple logistic regression analysis indicated that thrombocytopenia [odds ratio =2.260, 95% confidence interval (1.153, 4.429), P=0.018] and cardiopulmonary resuscitation duration [odds ratio=1.117, 95% confidence interval (1.060, 1.177), P<0.001] were independent risk factors for 28-day mortality in patients with in-hospital cardiac arrest. Conclusion Thrombocytopenia after restoration of spontaneous circulation is associated with poor short-term prognosis in patients with in-hospital cardiac arrest.
Since the outbreak of the coronavirus disease 2019, the incidence and mortality of cardiac arrest have increased significantly worldwide, and the management of cardiac arrest is facing new challenges. The European Resuscitation Council issued the 2021 European Resuscitation Council Guidelines in March 2021 to update the important parts of cardiopulmonary resuscitation and added recommendations for the management of cardiopulmonary resuscitation during the coronavirus disease 2019 epidemic. This article will compare the difference between this guideline and the 2020 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care and integrate some key points, review literature and then summarize the latest research progress in cardiopulmonary resuscitation since the outbreak of the coronavirus disease 2019 epidemic. The content mainly involves cardiopulmonary resuscitation during the coronavirus disease 2019 epidemic, early prevention, early recognition, application of new technologies, airway management, extracorporeal cardiopulmonary resuscitation and post-resuscitation treatment.
Elderly patients account for 80% of cardiac arrest patients. The incidence of poor neurological prognosis after return of spontaneous circulation of these patients is as high as 90%, much higher than that of young. This is related to the fact that the mechanism of hippocampal brain tissue injury after ischemia-reperfusion in elderly cardiac arrest patients is aggravated. Therefore, this study reviews the possible mechanisms of poor neurological prognosis after return of spontaneous circulation in elderly cardiac arrest animals, and the results indicate that the decrease of hippocampal perfusion and the number of neurons after resuscitation are the main causes of the increased hippocampal injury, among which oxidative stress, mitochondrial dysfunction and protein homeostasis disorder are the important factors of cell death. This review hopes to provide new ideas for the treatment of elderly patients with cardiac arrest and the improvement of neurological function prognosis through the comparative analysis of elderly and young animals.
Poisoning is a frequent reason for patients to seek emergency medical attention, and in severe cases, it can result in severe cardiac disease or cardiac arrest. American Heart Association published the guideline for the management of patients with cardiac arrest or life-threatening toxicity due to poisoning in Circulation on September 18, 2023. Based on the literature, this article interprets the suggestions related to neurotoxic substances in this guideline, mainly involving the clinical management of benzodiazepines, opioids, cocaine, local anesthetics, and sympathomimetic substances poisoning. By interpreting the recommended points of the guide in detail, it is hoped that it will be helpful for the diagnosis and treatment of readers.
The International Liaison Committee on Resuscitation published the 2022 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science with Treatment Recommendations in Circulation, Resuscitation, and Pediatrics in November 2022. This consensus updates and recommends important aspects of cardiopulmonary resuscitation based on recently published resuscitation evidence. Herein, we interpret the consensus focusing on adult cardiopulmonary resuscitation including basic life support (ventilation techniques, compressions pause, transport strategies during resuscitation, and resuscitation procedures in drowning), advanced life support (target temperature management, point-of-care ultrasound as a diagnostic tool during cardiac arrest, vasopressin and corticosteroids for cardiac arrest, and post-cardiac arrest coronary angiography), cardiopulmonary resuscitation education/implementation/team (survival prediction after resuscitation of patients with in-hospital cardiac arrest, basic life support training, advanced life support training, blended learning for life support education, and faculty development approaches for life support courses) and recovery positions on rescue scene. This consensus provides important guidance for clinical practice and clear hints for the development of clinical research.
On September 18th, 2023, the American Heart Association published clinical management guidelines for patients with poisoning-induced cardiac arrest and critical cardiovascular illness in Circulation. Considering the important role of the guidelines in clinical practice, our team has divided them into three sections for detailed interpretation based on the different toxic effects of the drugs. This article is the second part of the interpretation, which combines the literature to interpret the recommendations related to cardiotoxic substance poisoning in the guidelines, mainly involving the clinical management of beta blockers, calcium channel blockers, digoxin and other cardiac glycosides, as well as sodium channel blocker poisoning, aiming to assist colleagues in their clinical practice through a detailed explanation of the key recommendations in the guidelines.
ObjectiveTo investigate the risk factors affecting the 28-day neurological outcome after admission of patients with sepsis complicated with consciousness disorder, create a simple scoring system, and evaluate its predictive value for the poor neurological outcome.MethodsWe retrospectively collected and analyzed the demographic data, clinical data, 28-day survival status and neurologic outcome of patients with sepsis complicated with disturbance of consciousness admitted to the Emergency Department of West China Hospital of Sichuan University between June 1st, 2017 and May 31st, 2018. Independent risk factors for the 28-day neurologic outcome of patients with disturbance of consciousness were obtained through univariate analyses and multiple logistic regression analysis, and then the continuous variables of risk factors were converted to binary variables according to the cut-off values from receiver operating characteristic (ROC) curve analysis, a simple scoring system was established and it’s predictive value for 28-day neurological outcome of patients with sepsis complicated with consciousness disorder was assessed.ResultsA total of 149 patients with sepsis complicated with consciousness disorder were included in this study, including 103 males (69.1%) and 46 females (30.9%), with an average age of (58.2±18.6) years old. There were 72 patients (48.3%) with poor outcome of neurological function on Day 28 after admission. Multiple logistic regression analysis revealed that total bile acid [odds ratio (OR)=1.040, 95% confidence interval (CI) (1.004, 1.077), P=0.027], blood ammonia [OR=1.014, 95%CI (1.001, 1.027), P=0.030], pulmonary infection [OR=3.255, 95%CI (1.401, 7.566), P=0.006], and Glasgow Coma Score (GCS) [OR=0.837, 95%CI (0.739, 0.949), P=0.005] were independent influencing factors for the poor neurological function in patients with sepsis complicated with consciousness disorder on Day 28 after admission. The area under the ROC curve predicting the 28-day poor neurological function was 0.754 [95%CI (0.676, 0.832)], and the sensitivity and specificity were 79.2% and 63.6%, respectively.ConclusionFor emergency patients with sepsis complicated with consciousness disorder, a simple scoring system based on early GCS, pulmonary infection, serum ammonia, and total bile acid has a favorable predictive value for short-term neurological function.
