AbstractThe optimal dose and duration of tissue plasminogen activator (tPA) administered with ultrasound-facilitated catheter-directed thrombolysis (USCDT) to patients with acute PE remains to be determined. Our institution recently adopted a shorter duration (4 h) of USCDT and lower dosing strategy (tPA 1 mg/h) based on data from the OPTALYSE PE Trial. The purpose was to evaluate the implementation at our institution of shorter duration (4 h) of USCDT and lower dosing strategy (tPA 1 mg/h) as outlined by OPTALYSE PE Trial. This was a retrospective, si ngle-center, observational study included patients...
ConclusionsBedside carotid ultrasound enables rapid, sensitive and safe hemodynamic assessment, especially in critically ill patients.
This study evaluated the morphological changes of the lower limb and associated hemodynamic responses to different lower-body compression pressures (COMPs) in physically active, healthy individuals at rest. Each of the 32 participants underwent three trials with three different degrees of lower-body compression applied: “Low” (2.2±1.4 mmHg), “Medium” (12.9±3.9 mmHg), and “High” (28.8±8.3 mmHg). In each COMP, a cross-sectional area of leg muscles (CSAmuscle), subcutaneous fat (CSAfat), superficial vessels (SupV), deep arteries (DA), and deep veins...
CONCLUSIONS: CDA are not associated with a major occurrence of cerebrovascular events in a high-risk population of hypertensives. PMID: 31782281 [PubMed - as supplied by publisher]
Introduction: Size and morphology of carotid atherosclerotic plaques can be quantified by ultrasound (US) imaging. Carotid artery plaque size and gray-scale median (GSM) have been identified as risk markers for both cardiovascular events and stroke ADDIN EN.CITE ADDIN EN.CITE.DATA (1, 2). Unstable plaques have a thin fibrotic cap and a lipid or hemorrhagic core ADDIN EN.CITE ADDIN EN.CITE.DATA (3-6). A higher amount of lipid and hemorrhage have been observed in echolucent carotid plaques presenting as lower GSM compared to echogenic carotid plaques containing fibrotic tissue and calcification ADDIN EN.CITE ADDIN EN.CITE.DATA (7-10).

Shear wave ultrasound elastography can provide useful quantitative information on the mechanical properties of the spastic muscles in post-stroke patients. Nevertheless, new studies using common terminology and parameters are needed to develop reliable methods that could help in assessing treatment efficiency.

Conclusion: It should be kept in mind that spasticity in the upper extremity may develop in the pectoralis minor muscle, and may cause pressure on the neurovascular structures. Ultrasound-guided botulinum toxin injections can be a safe and effective treatment for PMS in a patent with post stroke spastic hemiparesis. PMID: 31774031 [PubMed - as supplied by publisher]
Conclusions: The present research on the carotid artery stenosis patient cohort suggests the significant association between the rs4977574, rs7857345 and rs3798220 polymorphisms and carotid artery stenosis as well as between the rs4977574 and rs7857345 polymorphisms and atherogenic stroke. The rs4977574 and rs7857345 polymorphisms in patients with carotid artery stenosis appear to affect a person's susceptibility to atherogenic brain ischemia. Our results need to be replicated in future studies.
