3D Deep Neural Network Segmentation of Intracerebral Hemorrhage: Development and Validation for Clinical Trials
AbstractIntracranial hemorrhage (ICH) occurs when a blood vessel ruptures in the brain. This leads to significant morbidity and mortality, the likelihood of which is predicated on the size of the bleeding event. X-ray computed tomography (CT) scans allow clinicians and researchers to qualitatively and quantitatively diagnose hemorrhagic stroke, guide interventions and determine inclusion criteria of patients in clinical trials. There is no currently available open source, validated tool to quickly segment hemorrhage. Using an automated pipeline and 2D and 3D deep neural networks, we show that we can quickly and accurately ...

Mental practice for treating upper extremity deficits in individuals with hemiparesis after stroke.
CONCLUSIONS: Moderate-certainty evidence shows that MP in addition to other treatment versus the other treatment appears to be beneficial in improving upper extremity activity. Moderate-certainty evidence also shows that MP in addition to other treatment versus the other treatment appears to be beneficial in improving upper extremity impairment after stroke. Low-certainty evidence suggests that ADLs may not be improved with MP in addition to other treatment versus the other treatment. Low-certainty evidence also suggests that MP versus conventional treatment may not improve upper extremity impairment. Further study is requ...

Treatment of Upper Limb Paresis With Repetitive Peripheral Nerve Sensory Stimulation and Motor Training: Study Protocol for a Randomized Controlled Trial
Discussion: This project represents a major step in developing a rehabilitation strategy with potential to have impact on the treatment of stroke patients with poor motor recovery in developing countries worldwide. The study preliminarily evaluates a straightforward, non-invasive, inexpensive intervention. If feasibility and preliminary efficacy are demonstrated, further investigations of the proposed intervention (underlying mechanisms/ effects in larger numbers of patients) should be performed.Trial Registration: NCT02658578.

Systematic Review and Meta-analysis of Methodological Quality in In Vivo Animal Studies of Subarachnoid Hemorrhage
AbstractAs a result of increased awareness of wide-spread methodological bias and obvious translational roadblocks in subarachnoid hemorrhage (SAH) research, various checklists and guidelines were developed over the past decades. This systematic review assesses the overall methodological quality of preclinical SAH research. An electronic search for preclinical studies on SAH revealed 3415 potential articles. Of these, 765 original research papers conducted in vivo in mice, rats, rabbits, cats, dogs, pigs, goats, and non-human primates with a focus on brain damage related to delayed cerebral vasospasm and early brain injury...

Goal-oriented attentional self-regulation training in individuals with acquired brain injury in a subacute phase: a pilot feasibility study
The primary aim of this prospective pilot study was to assess feasibility of implementing goal-oriented attentional self-regulation (GOALS) training in Slovenia with patients with multiple cognitive deficits after acquired brain injury in acute phase of recovery. Seven patients with acquired brain injury (i.e. stroke, traumatic brain injury, and subarachnoid hemorrhage) with a mean postinjury time of 4.3 months (SD = 1.25) and mean age of 34.5 years (SD = 18.6) were recruited for the study. The group program consisted of 10 sessions twice a week and included cognitive strategy training, social skills training, and psychoed...

Effect of intensive rehabilitation on improvement of activity of daily living after intracerebral hemorrhage: a retrospective observational study
Between 2008 and 2012, the intensity of rehabilitation therapy for the recovery phase of stroke was gradually increased at our hospital in line with the policy of Japan’s National Insurance System. Training hours increased from 0.8 to 2.5 hours/day without introducing any new techniques, programs, or equipment. The aim of this study was to investigate the effectiveness of the increased intensity of rehabilitation on the improvement of activity of daily living of patients with intracerebral hemorrhage. We retrospectively compared patient outcomes for the periods 2013–2017 (N = 162) and 2003–2007 (N = 116) using the ga...

Effects of voluntary and forced exercises on motor function recovery in intracerebral hemorrhage rats
Motor paralysis is a severe consequence of intracerebral hemorrhage (ICH) that reduces patient quality of life. Rehabilitation is beneficial for stroke patients. However, functional recovery depends on the exercise type, and which factors are effective during rehabilitation are unknown. We aimed to clarify the effect of voluntary and forced exercises for functional recovery in ICH rats. Male Sprague–Dawley rats were divided into three groups: forced treadmill running (F-Ex.), voluntary wheel cage running (V-Ex.) and no exercise (Non-Ex.). The effects of the two exercises on motor recovery were analyzed by determining the...

A multi-path 2.5 dimensional convolutional neural network system for segmenting stroke lesions in brain MRI images
Publication date: Available online 9 December 2019Source: NeuroImage: ClinicalAuthor(s): Yunzhe Xue, Fadi G. Farhat, Olga Boukrina, A.M. Barrett, Jeffrey R. Binder, Usman W. Roshan, William W. GravesAbstractAutomatic identification of brain lesions from magnetic resonance imaging (MRI) scans of stroke survivors would be a useful aid in patient diagnosis and treatment planning. It would also greatly facilitate the study of brain-behavior relationships by eliminating the laborious step of having a human expert manually segment the lesion on each brain scan. We propose a multi-modal multi-path convolutional neural network sys...

Change in the profile of causes of death after investigation of hospital deaths in Belo Horizonte, Brazil, 2017
Conclusion: The investigation on reported hospital deaths is one of the strategies to improve mortality statistics, reducing the occurrence of GC among reported deaths and changing the mortality profile in these facilities. The importance of continuous physician training in cause-of-death certification is emphasized.

Profile of deaths from unspecified stroke after investigation of garbage codes in 60 cities in Brazil, 2017
Conclusion: The investigations allowed the identification of subgroups of deaths due to stroke. In addition to the research, however, it is important to conduct physician training in the adequate filling in of the DC, in order to improve estimates of specific stroke mortality, and to enable appropriate targeting of health actions and services.

Aerobic Training and Mobilization Early Post-stroke: Cautions and Considerations
Knowledge gaps exist in how we implement aerobic exercise programs during the early phases post-stroke. Therefore, the objective of this review was to provide evidence-based guidelines for pre-participation screening, mobilization, and aerobic exercise training in the hyper-acute and acute phases post-stroke. In reviewing the literature to determine safe timelines of when to initiate exercise and mobilization we considered the following factors: arterial blood pressure dysregulation, cardiac complications, blood-brain barrier disruption, hemorrhagic stroke transformation, and ischemic penumbra viability. These stroke-relat...

Sensors, Vol. 19, Pages 3482: 3D Simulations of Intracerebral Hemorrhage Detection Using Broadband Microwave Technology
Persson Early, preferably prehospital, detection of intracranial bleeding after trauma or stroke would dramatically improve the acute care of these large patient groups. In this paper, we use simulated microwave transmission data to investigate the performance of a machine learning classification algorithm based on subspace distances for the detection of intracranial bleeding. A computational model, consisting of realistic human head models of patients with bleeding, as well as healthy subjects, was inserted in an antenna array model. The Finite-Difference Time-Domain (FDTD) method was then used to generate simulated t...
