Objective: The present study aimed to evaluate the relationship between all-cause mortality and the neutrophil percentage-to-albumin ratio (NPAR) in patients with atrial fibrillation (AF).
Methods: We obtained clinical information from patients with AF from the Medical Information Mart for Intensive Care-IV version 2.0 (MIMIC-IV) database and the Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University (WMU). The clinical endpoints were all-cause death measured at 30-day, 90-day, and one-year intervals. For endpoints associated with the NPAR, logistic regression models were used to calculate odds ratios (OR) with 95% confidence intervals (CI). Receiver operating characteristic (ROC) curves and area under the curve (AUC) were developed to compare the ability of different inflammatory biomarkers to predict 90-day mortality in patients with AF.
Results: Higher NPAR was associated with a higher risk of 30-day (OR 2.08, 95% CI 1.58-2.75), 90-day (OR 2.07, 95% CI 1.61-2.67), and one-year mortality (OR 1.60, 95% CI 1.26-2.04) in patients with AF in 2813 patients from MIMIC-IV. The predictive performance of NPAR (AUC = 0.609) for 90-day mortality was better than that of neutrophil-to-lymphocyte ratio (NLR) (AUC = 0.565, P < 0.001), and platelet-to-lymphocyte ratio (PLR) (AUC = 0.528, P < 0.001). When NPAR and sequential organ failure assessment (SOFA) were combined, the AUC increased from 0.609 to 0.674 (P < 0.001). Higher NPAR was associated with a higher risk of 30-day mortality (OR 2.54, 95% CI 1.02-6.30) and 90-day mortality (OR 2.76, 95% CI 1.09-7.01) in 283 patients from WMU.
Conclusion: An increased 30-day, 90-day, and one-year mortality risk among patients with AF were linked to a higher NPAR in MIMIC-IV. NPAR was thought to be a good predictor of 90-day all-cause mortality. Higher NPAR was associated with a higher risk of 30-day and 90-day mortality in WMU.

Safety and efficacy of intravenous thrombolysis: a systematic review and meta-analysis of 93,057 minor stroke patients.

Department of Neurology, RWTH Aachen University, Pauwels Street 30, Aachen, 52074, Germany.
Background: The definition of minor ischemic stroke (MIS) is a topic of debate, however, the most accepted definition is a stroke with National Institutes of Health Stroke Scale (NIHSS) ≤ 5. Intravenous thrombolysis (IVT) is a crucial treatment option for acute ischemic stroke (AIS) including: alteplase, recombinant human tissue-type plasminogen activator (r-tPA), and the recently approved tenecteplase. However, there is a debate regarding its safety and efficacy.

Background: Existing risk scores assessing geriatric vulnerability in the emergency department (ED) have shown limited predictive power, especially in diverse populations. We investigated the relationship of a quick and easy-to-administer geriatric vulnerability scoring system with functional decline and mortality in older patients admitted to multiple hospitals through the ED in the United States (US) and Brazil (BR).
Method: Federated, international, multicenter observational study of hospitalized ED patients aged ≥ 65 from US and BR.

Objective: Investigate whether deaf or hard of hearing (D/HH) patients with COVID-19 exhibited different hospitalisation outcomes compared with hearing patients with COVID-19.
Design: Cohort study SETTING: Statewide Inpatient Databases for Florida, Maryland, New York and Washington, for the year 2020.
Participants: Records of patients aged 18-64 years with COVID-19 PRIMARY OUTCOMES AND MEASURES: Differences in in-hospital death, 90-day readmission, length of stay, hospitalisation cost, hospitalisation cost per day, intensive care unit (ICU) or coronary care unit (CCU) utilisation and ventilation use were evaluated.

Introduction: Landmark thrombectomy trials demonstrated improved functional outcomes after endovascular therapy (EVT) for large core strokes (LCSs). This study explored the impact of recanalization attempts and procedure time (PT) on outcomes in LCS patients.
Patients And Methods: This was a retrospective study of patients with LCSs who underwent EVT from a prospective multicentre cohort.
