Long-Term Effect of Pravastatin on Carotid Intima-Media Complex Thickness Clinical Sciences
Conclusions—The usual Japanese dose of pravastatin significantly reduced the progression of carotid IMT at 5 years in patients with noncardioembolic stroke.Clinical Trial Registration—URL: http://www.clinicaltrials.gov. Unique identifier: NCT00361530.

Attention-Based UNet Deep Learning Model for Plaque Segmentation in Carotid Ultrasound for Stroke Risk Stratification: An Artificial Intelligence Paradigm
This study proposes an attention-channel-based UNet deep learning (DL) model that identifies the carotid plaques in the internal carotid artery (ICA) and common carotid artery (CCA) images. Our experiments consist of 970 ICA images from the UK, 379 CCA images from diabetic Japanese patients, and 300 CCA images from post-menopausal women from Hong Kong. We combined both CCA images to form an integrated database of 679 images. A rotation transformation technique was applied to 679 CCA images, doubling the database for the experiments. The cross-validation K5 (80% training: 20% testing) protocol was applied for accuracy deter...

Far wall plaque segmentation and area measurement in common and internal carotid artery ultrasound using U-series architectures: An unseen Artificial Intelligence paradigm for stroke risk assessment
Comput Biol Med. 2022 Aug 28;149:106017. doi: 10.1016/j.compbiomed.2022.106017. Online ahead of print.ABSTRACTStroke risk assessment using deep learning (DL) requires automated, accurate, and real-time risk assessment while ensuring compact model size. Previous DL paradigms suffered from challenges like memory size, low speed, and complex in nature lacking multi-ethnic, and multi-institution databases. This research segments and measures the area of the plaque far wall of the common carotid (CCA) and internal carotid arteries (ICA) in B-mode ultrasound using four types of solo, namely, UNet, UNet+, UNet++, and UNet+++, and...

Stenosis Length and Degree Interact With the Risk of Cerebrovascular Events Related to Internal Carotid Artery Stenosis
Conclusion: We found a statistically insignificant tendency for the ultrasound-measured length of sICAS<70% to be longer than that of sICAS≥70%. Moreover, the ultrasound-measured length of sICAS<90% was significantly longer than that of sICAS 90%. Among patients with sICAS≥70%, the degree and length of stenosis were inversely correlated. Larger studies are needed before a clinical implication can be drawn from these results. Introduction Internal carotid artery stenosis (ICAS) causes around one-fifth of ischemic cerebrovascular stroke and has the highest risk of early stroke recurrence...

Another Chance for Medtronic ’s Renal Denervation Therapy
Medtronic has yet another chance to prove its renal denervation therapy can treat uncontrolled hypertension. The Dublin-based company has received FDA approval to begin a clinical trial to evaluate the Symplicity Spyral renal denervation system with patients on medication for high blood pressure. The ON MED Trial is a 2:1 randomized, sham-controlled study and will randomize up to 340 patients at 55 centers in the U.S., Japan, Europe, Australia and Canada. Patients will be followed out to three years. Primary safety endpoints will include major adverse events at one month and new renal artery stenosis at six months. The pri...

Plant-Derived Alkaloids: The Promising Disease-Modifying Agents for Inflammatory Bowel Disease
Conclusion This paper summarizes the current findings regarding the anti-colitis activity of plant-derived alkaloids and shows how these alkaloids exhibit significant and beneficial effects in alleviating colonic inflammation. These natural alkaloids are not only promising agents for IBD treatment but are also components for developing new wonder drugs. However, the underlying molecular mechanisms or toxicological evaluation of most plant-derived alkaloids still require much scientific research, and their actual efficacies for IBD patients have not been verified well in field research. Thus, further clinical trials to elu...

Anthropometric Obesity Indices were Stronger than CT-Based Indices in Associations with Carotid Intima-Media Thickness in Japanese Men.
CONCLUSIONS: In community-dwelling Japanese men, anthropometric obesity indices, BMI in particular, were more strongly associated with carotid atherosclerosis than CT-based obesity indices. The association of general obesity with carotid atherosclerosis was strong and adding CT-based obesity measure did not considerably influence in the association.

Automated deep learning-based paradigm for high-risk plaque detection in B-mode common carotid ultrasound scans: an asymptomatic Japanese cohort study
CONCLUSIONS: The proposed study demonstrates a fast, accurate, and reliable solution for early detection and quantification of plaque lesions in common carotid artery ultrasound scans. The system runs on a test US image in < 1 second, proving overall performance to be clinically reliable.PMID:34825801 | DOI:10.23736/S0392-9590.21.04771-4
