Prediction of Ischemic Stroke Recurrence Based on COX Proportional Risk Regression Model and Evaluation of the Effectiveness of Patient Intensive Care Interventions
Comput Math Methods Med. 2022 Jun 20;2022:8392854. doi: 10.1155/2022/8392854. eCollection 2022.ABSTRACTWith the continuous improvement of medical technology and the aging of the population, the death rate of stroke is gradually decreasing, but the recurrence rate is still high, and the number of recurrences is increasing, resulting in disability and other symptoms, which brings great burden and distress to patients and their families. As the number of strokes increases, neurological impairment becomes more and more severe, affecting patients' ability to live, socialize, and work, and seriously reducing their quality of lif...

Why caution is recommended with post‐hoc individual patient matching for estimation of treatment effect in parallel‐group randomized controlled trials: The case of acute stroke trials
A post‐hoc individual patient matching procedure was recently proposed within the context of parallel group randomized clinical trials (RCTs) as a method for estimating treatment effect. In this paper, we consider a post‐hoc individual patient matching problem within a parallel group RCT as a multi‐objective decision‐making problem focussing on the trade‐off between the quality of individual matches and the overall percentage of matching. Using acute stroke trials as a context, we utilize exact optimization and simulation techniques to investigate a complex relationship between the overall percentage of individua...

Modeling the Inflammatory Response in the Hypothalamus ensuing Heat Stroke: Iterative cycle of Model Calibration, Identifiability Analysis, Experimental Design and Data Collection.
In this study, we developed a mathematical model to understand the interactions and dynamics of cytokines in the hypothalamus, the main thermoregulatory center in the brain. Uncertainty and identifiability analysis of the calibrated model parameters revealed non-identifiable parameters due to the limited amount of data. To overcome the lack of identifiability of the parameters, an iterative cycle of optimal experimental design, data collection, re-calibration and model reduction was applied and further informative experiments were suggested. Additionally, a new method of approximating the prior distribution of the paramete...

Bayesian inference for an illness-death model for stroke with cognition as a latent time-dependent risk factor
Longitudinal data can be used to estimate the transition intensities between healthy and unhealthy states prior to death. An illness-death model for history of stroke is presented, where time-dependent transition intensities are regressed on a latent variable representing cognitive function. The change of this function over time is described by a linear growth model with random effects. Occasion-specific cognitive function is measured by an item response model for longitudinal scores on the Mini-Mental State Examination, a questionnaire used to screen for cognitive impairment. The illness-death model will be used to identi...

Perfusion Angiography in Acute Ischemic Stroke.
Authors: Scalzo F, Liebeskind DS Abstract Visualization and quantification of blood flow are essential for the diagnosis and treatment evaluation of cerebrovascular diseases. For rapid imaging of the cerebrovasculature, digital subtraction angiography (DSA) remains the gold standard as it offers high spatial resolution. This paper lays out a methodological framework, named perfusion angiography, for the quantitative analysis and visualization of blood flow parameters from DSA images. The parameters, including cerebral blood flow (CBF) and cerebral blood volume (CBV), mean transit time (MTT), time-to-peak (TTP), and...

Prediction Model Construction for Ischemic Stroke Recurrence with BP Network and Multivariate Logistic Regression and Effect of Individualized Health Education
Comput Math Methods Med. 2022 Jun 22;2022:4284566. doi: 10.1155/2022/4284566. eCollection 2022.ABSTRACTStroke is an acute cerebrovascular disease caused by the rapid rupture or blockage of intracranial blood vessels for a variety of reasons, preventing blood from flowing into the brain and causing damage to brain tissue. The global burden of stroke disease is quickly increasing, and ischemic stroke (IS) accounts for 60 percent to 70 percent of all strokes, owing to the prevalence of people's bad lifestyles and the intensity of global ageing. Although most IS patients have received effective treatment, many patients still h...

Improving the Use of Blockchain Technology in Stroke Care Information Management Systems
This study focused on evaluating the application of blockchain technology in Stroke Nursing Information Management Systems. This emerging technology is already in use in the healthcare industry. The patient's data is kept decentralized, transparent, and mainly incorruptible, thus keeping it secured and sharing of data is quick.PMID:36199777 | PMC:PMC9529427 | DOI:10.1155/2022/2642841

Effects of Hypoxia-Inducible Factor 1 (HIF-1) Signaling Pathway on Acute Ischemic Stroke
CONCLUSION: By detecting the expression changes of Hesl+factor VII in the ischemic area, the results show that ischemia and hypoxia activate the HIF-1, making the HIF-l the main regulatory pathway in the process of angiogenesis after ischemia.PMID:36276989 | PMC:PMC9586786 | DOI:10.1155/2022/1860925
