Analysis of barriers associated with emergency medical service activation in patients with acute stroke and acute myocardial infarction from Zhongjiang County of Sichuan Province in China.

OBJECTIVES: The purpose of this study was to investigate the preferred modes of transportation to the hospital among patients with acute stroke and acute myocardial infarction (AMI), as well as to identify the factors that influence the utilization of ambulances. METHODS: We conducted a cross-sectional study, including patients who were diagnosed with acute stroke and AMI, at the people's hospital of Zhongjiang, from September 30th, 2022 to August 30th, 2023. All patients were divided into emergency medical service (EMS)-activation group and self-transportation group. Chi-square and t-tests were utilized to discern differences between groups at baseline. To screen relevant variables, we employed the Least Absolute Shrinkage and Selection Operator (LASSO) regression analysis using R package glmnet. Subsequently, we performed a logistic regression analysis to identify predictors of EMS activation according the results of LASSO regression. RESULTS: we collected 929 valid questionnaires. 26.16% of the patients required the services of EMS. 90.9% of individuals have not received any formal first aid education. 42.1% of them reported that they had no understanding of cardiovascular and cerebrovascular diseases. Diagnosed as AMI (OR 0.22, 95%CI 0.06 to 0.88) or acute cerebral infarction (OR 0.26, 0.10 to 0.68), the distance between the patient and the nearest 120 network hospital when the patient had these symptoms (OR 0.97, 0.94 to 0.99), the patient's son or daughter was there when the patient was symptomatic (OR 0.58, 0.37 to 0.94), the patient (OR 0.19, 0.05 to 0.72) and the patient's partner (wife or husband) (OR 0.36, 0.16 to 0.85) had decided that the patient needed further medical help, Among patients who did not seek immediate help after symptom onset, thinking that the symptoms will disappear spontaneously (OR 0.34, 0.13 to 0.92) or not wanting to disturb others (OR 0.06, 0.01 to 0.66) or believing that they are not important symptoms (OR 0.15, 0.05 to 0.42) were factors independently associated with less ambulance use. Age (OR 1.02, 1.00 to 1.04), Stroke patients have experienced symptoms of disturbance of consciousness or convulsions (OR 2.99, 1.72 to 5.2) were independent factors associated with increased ambulance use. CONCLUSION: There is still ambulance underutilization among patients with acute stroke and AMI in county territory of China. Moreover, it is needed to raise the level of first aid education and awareness about EMS. Additionally, private clinic doctors and the public should gain adequate understanding of the severity of acute stroke and AMI, as well as their common symptoms, the crucial importance of prompt medical intervention. Finally, we propose that all township hospitals should be integrated into the 120 emergency networks and equipped with emergency first aid capabilities, pre-hospital care, and transportation abilities.

Immune checkpoint inhibitor-associated acute kidney injury in patients with cancer: a systematic review and meta-analysis of risk factors.

BACKGROUND: As a novel antineoplastic drug, immune checkpoint inhibitors (ICIs) are associated with a spectrum of autoimmune-related side effects, including acute kidney injury (AKI). Understanding the risk factors for immune-associated acute kidney injury will inform future symptom management measures to reduce this risk. This study aims to identify the risk factors for ICIs-AKI in cancer patients through a systematic review and meta-analysis. METHODS: The systematic search was conducted in The Cochrane Library, Pubmed, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Data, and VIP Database. The related studies published since the establishment of the database to Aug 22, 2022, were screened, data was extracted following the inclusion and exclusion criteria, and the quality of the selected studies was assessed by Newcastle-Ottawa Scale (NOS). The above was performed independently by the two reviewers. The estimated pooled odds ratios (ORs) for risk factors of developing ICIs-AKI were conducted by random-effects meta-analysis. RESULTS: A total of 8 publications, including 5267 patients, were included. Meta-analysis results showed that extrarenal immune-related adverse events (irAEs), therapy with the cytotoxic T-lymphocyte-associated protein 4 (CTLA-4), male, hypertension, pre-existent use of a diuretic, and a proton pump inhibitor (PPI) were significantly correlated to ICIs-AKI. CONCLUSIONS: We identified extrarenal irAEs, CTLA-4 treatments, males, hypertension, previous use of diuretics, and PPIs are essential predictors of ICIs-AKI. These findings are helpful for healthcare providers to monitor ICIs-AKI for management and timely interventions.
