Developing new quantitative CT image markers to predict prognosis of acute ischemic stroke patients
CONCLUSIONS: This study demonstrates feasibility of developing a new quantitative imaging method and marker to predict AIS patients' prognosis in the hyperacute stage, which can help clinicians optimally treat and manage AIS patients.PMID:35213340 | DOI:10.3233/XST-221138

A brain CT-based approach for predicting and analyzing stroke-associated pneumonia from intracerebral hemorrhage
DiscussionOur findings suggest that our method is effective in classifying the development of pneumonia based on brain CT scans. Furthermore, we identified distinct characteristics, such as volume and distribution, of ICH in four different types of SAP.

Robot-Assisted Therapy in Upper Extremity Hemiparesis: Overview of an Evidence-Based Approach
Conclusion Robotic therapy has matured and represents an embodiment of a paradigm shift in neurorehabilitation following a stroke: instead of focusing on compensation, it affords focus in ameliorating the impaired limb in line with concepts of neuroplasticity. This technology-based treatment provides intensity, interactivity, flexibility, and adaptiveness to patient's performance and needs. Furthermore, it increases the productivity of rehabilitation care. Of course, efficiency must be discussed within a local perspective. For example, following the cost containment shown in the VA ROBOTICS study (46), the UK Nati...

A Kinematic Study of Progressive Micrographia in Parkinson's Disease
This study has investigated the kinematic features of progressive micrographia during a repetitive writing task. Twenty-four PD patients with duration since diagnosis of <10 years and 24 age-matched controls wrote the letter “e” repeatedly. PD patients were studied in defined off states, with scoring of motor function on the Unified Parkinson's Disease Rating Scale Part III. A digital tablet captured x-y coordinates and ink-pen pressure. Customized software recorded the data and offline analysis derived the kinematic features of pen-tip movement. The average size of the first and the last fi...

How John Fetterman Came Out of the Darkness
When he looks back on the past year—a year in which he nearly died, became a U.S. Senator, and nearly died again—it is the debate that John Fetterman identifies as the ­breaking point. “The debate lit the mitch,” he says, then shakes his head in frustration and tries again. The right word is there in his brain, but he struggles to get it out. “Excuse me, that should be lit the mitch—” He stops and tries again. “Lit the match,” he says finally. Oct. 25, 2022: the date is lodged in his mind. “I knew I had to do it,” he tells me. “I knew that the vote...

A Case of Transient Global Amnesia: A Review and How It May Shed Further Insight into the Neurobiology of Delusions
Conclusion In closing, our patient’s episode of TGA combined with her emotional and perceptual response lends credence to the proposal of a “fear/paranoia” circuit in the genesis of paranoid delusions—a circuit incorporating amygdala, frontal, and parietal cortices. Here, neutral or irrelevant stimuli, thoughts, and percepts come to engender fear and anxiety, while dysfunction in frontoparietal circuitry engenders inappropriate social predictions and maladaptive inferences about the intentions of others.[54] Hippocampus relays information about contextual information based on past experiences and the current situat...

How one ED uses telemedicine in the ambulance
When you think of telemedicine, what comes to mind? Often the answer is a split screen—physician and patient in separate locations on their computers or tablets. But one health system has shown the true breadth of telemedicine’s reach by using the technology to treat patients during the critical early moments of a stroke. Find out how. The risk of damage and disability in patients who are experiencing a stroke increases with any delay in care delivery. Two emergency physicians at the University of Virginia (UVA) Health System understood the need for speed when it comes to caring for patients in the midst of acute str...

Modifiable Lifestyle Factors and Cognitive Function in Older People: A Cross-Sectional Observational Study
Conclusions: Lifestyle factors, such as physical activity, sleep, and social activity appear to be associated with cognitive function among older people. Physical activity and appropriate durations of sleep and conversation are important for cognitive function. Introduction Dementia is a major public health issue worldwide, with a serious burden for patients, caregivers, and society, as well as substantial economic impacts (1). Although the prevalence of late-life cognitive impairment and dementia are expected to increase in future, effective disease-modifying treatments are currently unavailable. Therefore, unders...

Can You Think Yourself Into A Different Person?
For years she had tried to be the perfect wife and mother but now, divorced, with two sons, having gone through another break-up and in despair about her future, she felt as if she’d failed at it all, and she was tired of it. On 6 June 2007 Debbie Hampton, of Greensboro, North Carolina, took an overdose of more than 90 pills – a combination of ten different prescription drugs, some of which she’d stolen from a neighbor’s bedside cabinet. That afternoon, she’d written a note on her computer: “I’ve screwed up this life so bad that there is no place here for me and nothing I can contr...

Automated quantification of cerebral edema following hemispheric infarction: Application of a machine-learning algorithm to evaluate CSF shifts on serial head CTs
In conclusion, we have developed and validated an accurate automated approach to segment CSF and calculate its shifts on serial CT scans. This algorithm will allow us to efficiently and accurately measure the evolution of cerebral edema in future studies including large multi-site patient populations.
