Improvement of diagnostic performance of hyperacute ischemic stroke in head CT using an image-based noise reduction technique with non-black-boxed process
To date, a variety of image-based noise reduction (INR) techniques for computed tomography (CT) have been reported. They are based on iterative processes or deep learning techniques. Some INR products using iterative processes are already commercially available and have been reported to exhibit noise reduction performance better than hybrid-type iterative reconstruction (HIR) in abdominal CT [1,2]. However, the details of the processes inside these commercial INR systems are usually proprietary and cannot be readily replicated outside.

Social bias in artificial intelligence algorithms designed to improve cardiovascular risk assessment relative to the Framingham Risk Score: a protocol for a systematic review
This study will employ an equity-lens to identify sources of bias (ie, race/ethnicity, gender and social stratum) in ML algorithms designed to improve CVD risk assessment relative to the FRS. A comprehensive literature search will be completed using MEDLINE, Embase and IEEE to answer the research question: do AI algorithms that are designed for the estimation of CVD risk and that compare performance with the FRS address the sources of bias inherent in the FRS? No study date filters will be imposed on the search, but English language filters will be applied. Studies describing a specific algorithm or ML approach that provid...

Locomotor adaptation on a split-belt treadmill in adults with stroke: a systematic review
An Sist Sanit Navar. 2023 Apr 27;46(1):e1035. doi: 10.23938/ASSN.1035.ABSTRACTThis systematic review aimed to assess the efficacy of motor adaptation during walking on a split-belt treadmill (SBT) under different learning conditions in adults with stroke. We searched randomized clinical trials and case studies that used SBT under different learning conditions published between January 2011 and April 2022 in four databases: Pubmed, Scopus, Web of Science, and Brain-URJC. The following data were extracted: objectives, interventions, population, number of sessions, outcome measures, and results. The methodological quality of ...

Hand-Arm Bimanual Intensive Therapy Including Lower Extremities (HABIT-ILE) in adults with chronic stroke: protocol of a randomised controlled trial
This study will compare the effect of 50 hours of HABIT-ILE against usual motor activity and regular rehabilitation. HABIT-ILE will be provided in a 2-week, adult’s day-camp setting, promoting functional tasks and structured activities. These tasks will continuously progress by increasing their difficulty. Assessed at baseline, 3 weeks after and at 3 months, the primary outcome will be the adults-assisting-hand-assessment stroke; secondary outcomes include behavioural assessments for hand strength and dexterity, a motor learning robotic medical device for quality of bimanual motor control, walking endurance, question...

Improving sleep and learning in rehabilitation after stroke, part 2 (INSPIRES2): study protocol for a home-based randomised control trial of digital cognitive behavioural therapy (dCBT) for insomnia
Introduction
Consolidation of motor skill learning, a key component of rehabilitation post-stroke, is known to be sleep dependent. However, disrupted sleep is highly prevalent after stroke and is often associated with poor motor recovery and quality of life. Previous research has shown that digital cognitive behavioural therapy (dCBT) for insomnia can be effective at improving sleep quality after stroke. Therefore, the aim of this trial is to evaluate the potential for sleep improvement using a dCBT programme, to improve rehabilitation outcomes after stroke.
Methods and analysis
We will conduct a parallel-arm randomised c...

Development of rapid and effective risk prediction models for stroke in the Chinese population: a cross-sectional study
Conclusion
The five machine learning models all had good predictive and discriminatory performance for stroke. The performance of RF and XGBoost was slightly better than that of LR, which was easier to interpret and less prone to overfitting. This work provides a rapid and accurate tool for stroke risk assessment, which can help to improve the efficiency of stroke screening medical services and the management of high-risk groups.

Association between seropositivity for toxocariasis and cognitive functioning in older adults: an analysis of cross-sectional data from the US National Health and Nutrition Examination Survey (NHANES), 2011-2014
Conclusions
In our study, seropositive toxocariasis was independently and significantly associated with worse working memory, sustained attention, processing speed and global cognition in older adults. If this association is causal, public health measures to prevent human toxocariasis might help protect older adults’ cognitive function.

Accuracy of Stroke Risk Prediction Models by Race, Sex, and Age
This retrospective cohort study compares stroke-specific algorithms with pooled cohort equations developed for atherosclerotic cardiovascular disease for the prediction of new-onset stroke across different subgroups (race, sex, and age) and the added value of novel machine learning techniques.
