The Great Contrast Shortage of 2022 —Lessons learnt in Australia
ConclusionOur findings demonstrate that the IBCM shortage crisis had a very significant impact on the delivery of healthcare. While V/Q scans could (partially) substitute for CTPA studies in suspected pulmonary emboli, there appeared to be no valid alternative for CTNA studies in stroke calls. The unexpected and critical shortage of IBCM forced healthcare professionals to conserve resources, prioritise indications, triage patients based on risk, explore alternate imaging strategies and prepare for similar events recurring in the future.

Comparison of Parameters for Assessment of Carotid Stiffness and Their Association with Carotid Atherosclerosis in Rural Australian Adults: A Pilot Study
J Clin Med. 2023 Apr 18;12(8):2935. doi: 10.3390/jcm12082935.ABSTRACTCarotid stiffness has been associated with the development and progression of carotid artery disease and is an independent factor for stroke and dementia. There has also been a lack of comparison of different ultrasound-derived carotid stiffness parameters and their association with carotid atherosclerosis. This pilot study aimed to investigate the associations between carotid stiffness parameters (derived via ultrasound echo tracking) and the presence of carotid plaques in Australian rural adults. In cross-sectional analyses, we assessed forty-six subjec...

How Virtual Reality Is Expanding Health Care
Clinicians can help patients recover from strokes while they’re anywhere in the world—even states or countries far away from each other—by using a combination of robotics and virtual-reality devices.
It’s happening at Georgia Institute of Technology, where Nick Housley runs the Sensorimotor Integration Lab. There, patients undergoing neurorehabilitation, including those recovering from a stroke, are outfitted with robotic devices called Motus, which are strapped to their arms and legs. The goal: to speed up recovery and assist with rehabilitation exercises. Patients and practitioners using the syste...

Occlusive Disease and Upright Activity in Acute Ischemic Stroke
The impact of out-of-bed upright activity on outcomes in ischemic stroke patients with severe extra- and intracranial stenosis or occlusion is unknown. Using ultrasound findings from a cohort recruited to A Very Early Rehabilitation Trial (AVERT) which compared higher dose very early mobilisation (VEM) to usual care (UC), we aimed to explore the association between occlusive disease and 3-month outcomes and occlusive disease-by-mobilisation treatment interactions. Participants with ischemic stroke, with carotid and transcranial Doppler ultrasounds performed ≤1 week after admission, were included in this single centre sub...

The association between carotid atherosclerosis and treatment with lithium and antipsychotics in patients with bipolar disorder.
CONCLUSION: Lithium treatment may be associated with less progression in carotid intima-media thickness and the reduced risk for atherosclerosis in adults with bipolar disorder, including those with high cardiovascular disease risk. In addition to age and body mass index, antipsychotics may increase carotid intima-media thickness even in the low cardiovascular disease-risk patients.

Asymptomatic Carotid Stenosis Is Associated With Circadian and Other Variability in Embolus Detection
Conclusions: Embolism associated with asymptomatic carotid stenosis shows circadian variation with highest rates 4–6 h before midday. This corresponds with peak circadian incidence of stroke and other vascular complications. These and ASED Study results show that monitoring frequency, duration, and time of day are important in ES detection.
Introduction
Transcranial Doppler (TCD) detected microembolism in the ipsilateral middle cerebral artery (MCA) may help stratify the risk of stroke and other arterial disease complications in persons with advanced (≥60%) asymptomatic carotid stenosis. If so, this t...

Cardiovascular Programming During and After Diabetic Pregnancy: Role of Placental Dysfunction and IUGR
This study demonstrated that the incidence of ischemic heart disease and death were three times higher among men with low birth weight compared to men with high birth weight (5). Epidemiological investigations of adults born at the time of the Dutch famine between 1944 and 1945 revealed an association between maternal starvation and a low infant birth weight with a high incidence of hypertension and coronary heart disease in these adults (23). Furthermore, Painter et al. reported the incidence of early onset coronary heart disease among persons conceived during the Dutch famine (24). In that regard, Barker's findin...

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...

IJERPH, Vol. 16, Pages 521: Shift Work Including Night Work and Long Working Hours in Industrial Plants Increases the Risk of Atherosclerosis
We examined arterial stiffness (central blood pressure, augmentation pressure and index, and pulse wave velocity) by the use of SphygmoCor&reg; (AtCor Medical Pty Ltd, Sydney, Australia) and the carotid arteries by ultrasound. We assessed VO2max by bicycle ergometry. We applied linear and logistic regression to evaluate associations between total number of years in shift work and cardiovascular outcome measures. The day workers were older and had more pronounced arterial stiffness compared to the shift workers. Number of years as a shift worker was associated with increased carotid intima media thickness (max IMT) ...

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...

Restenosis and risk of stroke after stenting or endarterectomy for symptomatic carotid stenosis in the International Carotid Stenting Study (ICSS): secondary analysis of a randomised trial
This report presents a secondary analysis, and follow-up is complete.FindingsBetween May, 2001, and October, 2008, 1713 patients were enrolled and randomly allocated treatment (855 were assigned stenting and 858 endarterectomy), of whom 1530 individuals were followed up with ultrasound (737 assigned stenting and 793 endarterectomy) for a median of 4·0 years (IQR 2·3–5·0). At least moderate restenosis (≥50%) occurred in 274 patients after stenting (cumulative 5-year risk 40·7%) and in 217 after endarterectomy (29·6%; unadjusted hazard ratio [HR] 1·43, 95% CI 1·21–1·72; p<0·0001). Patients with at least mo...

EBR Systems launches trial for wireless pacer
EBR Systems said yesterday that it launched a 350-patient investigational device exemption trial of its Wise wireless pacemaker it hopes to use to win FDA approval.
Sunnyvale, Calif.-based EBR’s device uses a subcutaneous generator to wirelessly deliver ultrasound energy to a “pellet” implanted in the right ventricle, which it uses to synchronize the left and right ventricles. The system is designed to eliminate the need for a left ventricular lead by allowing the operating physician to place the stimulation “pellet” in a patient-specific location inside the left ventricle.
The FDA approved the Solve-CRT stu...
