Background: Previous studies have identified insufficient knowledge of stroke symptoms and risk factors both among survivors of stroke and in the general population. The purpose of this study was to investigate knowledge of stroke symptoms and risk factors in a Norwegian stroke population and to identify factors associated with good knowledge.
Methods: This prospective study included patients with acute transient ischemic attack, ischemic stroke, and intracerebral hemorrhage. Knowledge of stroke symptoms and risk factors was explored by asking open-ended questions. Bivariate and multivariate regression analyses were performed to identify factors related to good knowledge.
Results: In total, 287 patients (mean age ± standard deviation, 70.0 ± 12.9 years) answered the open-ended questionnaire of which 71% knew at least 1 symptom of stroke whereas 43% knew at least 1 risk factor. Knowledge of both numbness/weakness and speech difficulties as symptoms of stroke (43% of the patients) was associated with lower age (odds ratio [OR], .96; 95% confidence interval [CI], .94-.99), higher education (OR, 2.25; 95% CI, 1.17-4.30), and having previously received information regarding stroke (OR, 7.74; 95% CI, 3.82-15.67). Knowing at least 2 of the 3 risk factors of stroke "smoking", "hypertension", and "diabetes" (14% of the patients) was associated with lower age (OR, .94; 95% CI, .92-.97).
Conclusions: Knowledge of stroke symptoms and risk factors in patients with acute cerebrovascular disease seems to be insufficient. Further educational efforts are needed, as better knowledge may improve prevention of stroke and increase the number of patients who can receive thrombolysis.

Mayo Clinic, Rochester, Minnesota, United States.
In this study, we first analyzed data from 147 patients with solitary plasmacytomas treated at the Mayo Clinic between 2005 and 2022 and then expanded our investigation through a systematic review and meta-analysis of 62 studies, encompassing 3,487 patients from the years 1960 to 2022. Our findings reveal that patients with up to 10% clonal plasma cells in their bone marrow (BM), denoted as plasmacytoma +, had a significantly reduced median disease-free survival (DFS) of 15.7 months vs.

Background: Gastrointestinal bleeding (GIB) is a severe and potentially life-threatening complication in patients with acute myocardial infarction (AMI), significantly affecting prognosis during hospitalization. Early identification of high-risk patients is essential to reduce complications, improve outcomes, and guide clinical decision-making.
Objective: This study aimed to develop and validate a machine learning (ML)-based model for predicting in-hospital GIB in patients with AMI, identify key risk factors, and evaluate the clinical applicability of the model for risk stratification and decision support.
Migration of Health Workers and Its Impacts on the Nigerian Health Care Sector: Protocol for a Scoping Review.

Department of Medicine and Optometry, eHealth Institue, Linnaeus University, Kalmar, Sweden.
Background: Health worker migration from Nigeria poses significant challenges to the Nigerian health care sector and has far-reaching implications for health care systems globally. Understanding the factors driving migration, its effects on health care delivery, and potential policy interventions is critical for addressing this complex issue.
Objective: This study aims to comprehensively examine the factors encouraging the emigration of Nigerian health workers, map out the effects of health worker migration on the Nigerian health system, document the loss of investment in health training and education resulting from migration, identify relevant policy initiatives addressing migration, determine the effects of Nigerian health worker migration on destination countries, and identify the benefits and demerits to Nigeria of health worker migration.

Background: The utility of aging metrics that incorporate cognitive and physical function is not fully understood.
Objective: We aim to compare the predictive capacities of 3 distinct aging metrics-motoric cognitive risk syndrome (MCR), physio-cognitive decline syndrome (PCDS), and cognitive frailty (CF)-for incident dementia and all-cause mortality among community-dwelling older adults.
Methods: We used longitudinal data from waves 10-15 of the Health and Retirement Study.
