Ipsilateral and contralateral carotid stenosis contribute to the outcome of reperfusion treatment for ischemic stroke
DiscussionAccording to our findings, ICS and CCS negatively influence AIS patients' outcome treated by interventional therapies. ICS might exert an unfavorable effect both by cerebral hypoperfusion and by continuous microembolization toward ischemic area, while CCS is probable involved in reducing the collateral circles effectiveness. The importance of early carotid stenosis detection and treatment should then be reevaluated not only to manage the prevention approaches but also to obtain insights about post-stroke treatment strategies efficacy.

Effects of adjuvant berberine therapy on acute ischemic stroke: A meta-analysis
Phytother Res. 2023 Jul 8. doi: 10.1002/ptr.7920. Online ahead of print.ABSTRACTWe conducted a meta-analysis to evaluate the clinical efficacy of berberine (BBR) in treating acute ischemic stroke (AIS), explore its anti-inflammatory effects, and assess its potential applications for AIS patients. We comprehensively searched nine databases from inception until July 1, 2022, to identify clinical trials investigating the use of BBR in treating AIS. We performed statistical analyses using RevMan5.4 software and focused on primary outcomes such as inflammatory markers as well as secondary outcomes including immune system indica...

How AI Is Changing Medical Imaging to Improve Patient Care
That doctors can peer into the human body without making a single incision once seemed like a miraculous concept. But medical imaging in radiology has come a long way, and the latest artificial intelligence (AI)-driven techniques are going much further: exploiting the massive computing abilities of AI and machine learning to mine body scans for differences that even the human eye can miss.
Imaging in medicine now involves sophisticated ways of analyzing every data point to distinguish disease from health and signal from noise. If the first few decades of radiology were about refining the resolution of the pictures taken of...

Clinical improvement after cranioplasty and its relation to body position and cerebral hemodynamics
AbstractCranioplasty after decompressive craniectomy (DC) has been found to improve the neurological condition. The underlying mechanisms are still unknown. The aim of this study is to investigate the roles of the postural changes and atmospheric pressure (AP) in the brain hemodynamics and their relationship with clinical improvement. Seventy-eight patients were studied before and 72 h after cranioplasty with cervical and transcranial color Doppler ultrasound (TCCS) in the sitting and supine positions. Craniectomy size, shape, and force exerted by the AP (torque) were calculated. Neurological condition was assessed with ...

12 Innovations That Will Change Health Care and Medicine in the 2020s
Pocket-size ultrasound devices that cost 50 times less than the machines in hospitals (and connect to your phone). Virtual reality that speeds healing in rehab. Artificial intelligence that’s better than medical experts at spotting lung tumors. These are just some of the innovations now transforming medicine at a remarkable pace.
No one can predict the future, but it can at least be glimpsed in the dozen inventions and concepts below. Like the people behind them, they stand at the vanguard of health care. Neither exhaustive nor exclusive, the list is, rather, representative of the recasting of public health and medic...

Acute Ischemic Stroke in Pregnancy
Stroke is an uncommon but serious potential complication of pregnancy. The management of acute ischemic stroke in pregnant women remains a complex challenge that extends beyond the limits of clinical trial evidence. Patient 1 was a 29-year-old woman 27 weeks into her first pregnancy, without remarkable past medical history or vascular risk factors. She was admitted 1 h after sudden onset of a left total anterior circulation syndrome (National Institute of Health Stroke Scale [NIHSS] score of 23). CT and angio-CT scans were normal. Thrombolysis was performed, with mild clinical improvement. Brain MRI showed multi-territoria...

Clinical Importance of Temporal Bone Features for the Efficacy of Contrast-Enhanced Sonothrombolysis: a Retrospective Analysis of the NOR-SASS Trial
AbstractContrast-enhanced sonothrombolysis (CEST) seems to be a safe and promising treatment in acute ischemic stroke. It remains unknown if temporal bone features may influence the efficacy of CEST. We investigated the association between different temporal bone features on admission computed tomography (CT) scan and the outcome in acute ischemic stroke patients included in the randomized Norwegian Sonothrombolysis in Acute Stroke Study (NOR-SASS). Patients diagnosed as stroke mimics and those with infratentorial stroke or with incorrect insonation were excluded. We retrospectively assessed temporal bone heterogeneity (pr...

Neural Analytics launches study of transcranial doppler for evaluating mild-TBI
Neural Analytics said today it enrolled the 1st patient in a 2-year study exploring the use of its Lucid M1 transcranial doppler ultrasound system to evaluate cerebral blood flow in patients with mild traumatic brain injuries.
The Lucid M1 system is a portable all-in-one ultrasound system designed for measuring and displaying cerebral blood flow velocities in patients with brain disorders, the Los Angeles, Calif.-based company said.
In the 240-patient trial, researchers at the University of California Los Angeles will examine high school and college age enrollees in 3 separate groups, including those who have been affected...

Normal Findings on Pretreatment Transcranial Ultrasound in Patients Treated with Sonothrombolysis
In populations with a high (≥14) median National Institute of Health Stroke Score (NIHSS), a normal finding of Thrombolysis in Brain Ischemia grade 5 (TIBI 5) in the artery of interest has been reported to be an unusual finding when transcranial ultrasound is performed during thrombolysis. In such instances, a stroke mimic can be suspected, but there are alternative pathophysiological explanations. In this case series, the median NIHSS was relatively low (5), and 33% (6/18) of the patients treated with thrombolysis had TIBI 5 in the artery of interest at the time of treatment initiation. These 6 patients had normal findi...
