Posterior Circulation Ischaemic Stroke
Am J Med Sci. 2022 Jan 29:S0002-9629(22)00030-1. doi: 10.1016/j.amjms.2021.10.027. Online ahead of print.ABSTRACTPosterior circulation ischaemic stroke (PCIS) is a disease of high burden. They account for 20-25% of all ischaemic strokes. However, it is relatively under-researched and requires more clinical attention, since it carries worse functional outcomes. Vertigo, visual disturbances and sensory/motor disturbances are found in PCIS. Large artery atherosclerosis and embolism are main causes of PCIS, while there is growing evidence that vertebrobasilar dolichoectasia is a key association. Hypertension is the commonest r...

P-003 Association between baseline serology and symptomatic intracranial hemorrhage after endovascular thrombectomy for acute ischemic stroke
ConclusionOur findings, particularly the association of diabetes mellitus and high neutrophil count with post-EVT hemorrhage, support experimental data on the role of thromboinflammation in hemorrhagic transformation of large vessel occlusions.Disclosures J.

Intraoperative hypotension and perioperative acute ischemic stroke in patients having major elective non-cardiovascular non-neurological surgery
ConclusionOur analysis suggests that when MAP is less than 60  mmHg for more than 20 min, there is increased odds of acute ischemic stroke. Further studies are needed to determine what MAP should be targeted during surgery to optimize cerebral perfusion and limit ischemic stroke risk.

Experimental Rodent Models of Vascular Dementia: A Systematic Review.
Abstract Vascular dementia (VaD) occurs due to cerebrovascular insufficiency, which leads to decreased blood circulation to the brain, thereby resulting in mental disabilities. The main causes of vascular cognitive impairment (VCI) are severe hypoperfusion, stroke, hypertension, large vessel disease (cortical), small vessel disease (subcortical VaD), strategic infarct, hemorrhage (microbleed), cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), and cerebral amyloid angiopathy (CAA),which leads to decreased cerebrovascular perfusion. Many metabolic disorders such as...

Perturbations in myocardial perfusion and oxygen balance in swine with multiple risk factors: a novel model of ischemia and no obstructive coronary artery disease
In conclusion, common comorbidities in swine result in CMD, in the absence of appreciable atherosclerosis, which is severe en ough to produce perturbations in myocardial oxygen balance, particularly during exercise, resembling key features of INOCA.

Perfusion Assessment in Critical Limb Ischemia: Principles for Understanding and the Development of Evidence and Evaluation of Devices: A Scientific Statement From the American Heart Association.
Abstract There are >12 million patients with peripheral artery disease in the United States. The most severe form of peripheral artery disease is critical limb ischemia (CLI). The diagnosis and management of CLI is often challenging. Ethnic differences in comorbidities and presentation of CLI exist. Compared with white patients, black and Hispanic patients have higher prevalence rates of diabetes mellitus and chronic renal disease and are more likely to present with gangrene, whereas white patients are more likely to present with ulcers and rest pain. A thorough evaluation of limb perfusion is important in the ...

A perfusion territory shift attributable solely to the secondary collaterals in moyamoya patients: a potential risk factor for preoperative hemorrhagic stroke revealed by t-ASL and 3D-TOF-MRA.
CONCLUSIONS: t-ASL could reveal comprehensive MMD cerebral blood perfusion and the vivid perfusion territory shifts fed by the unilateral ICA and ECA and bilateral VAs in a noninvasive, straightforward, nonradioactive, and nonenhanced manner. 3D-TOF-MRA could subdivide t-ASL perfusion territory shifts according to their shunt arteries. A perfusion territory shift attributable to the secondary collaterals is a potential independent risk factor for preoperative hemorrhage in MMD patients. A perfusion territory shift fed by the primary collaterals may not have a strong effect on preoperative hemorrhage in MMD patients. These ...

The effects of diffusion and perfusion MRI mismatch on the admission blood glucose and blood pressure values measured in the first 12 hours of acute stroke
In this study, we examined the relationship between the presence of diffusion-weighted imaging (DWI)/perfusion-weighted imaging (PWI) mismatch, admission blood glucose level, and admission blood pressure level in patients who were admitted in the first 12 hours after onset. We studied 212 patients who were prospectively and consecutively registered to the stroke unit from 2006 to 2009. Correlations between mismatch and admission blood pressure level (ABPL) and admission blood glucose level (ABGL) were analyzed using multivariate logistic regression. Mismatch (P = .064, adjusted OR = 2.297, 95% CI, 0.953–5.536) wa...

Conveniently-Grasped Field Assessment Stroke Triage (CG-FAST): A Modified Scale to Detect Large Vessel Occlusion Stroke
Conclusions: CG-FAST scale could be an effective and simple scale for accurate identification of LVOS among AIS patients. Introduction Large vessel occlusion stroke (LVOS) often leads to severe disability and mortality. Although endovascular therapy (EVT) has been proved to be effective for LVOS patients (1–9), especially in anterior circulation, its benefit is highly time-dependent (10, 11). As hospitals with around-the-clock endovascular capability are scarce in many parts of the world and patients admitted directly to a CSC would have better outcomes than those receiving drip and ship treatment (12, 13), t...

Influence of Sex on Stroke Prognosis: A Demographic, Clinical, and Molecular Analysis
Conclusion Our data suggest that women who suffer from IS present with a poorer functional outcome than men at 3-months, regardless of other preclinical and clinical factors during the acute phase. These relationships seem to be mediated by atrial dysfunction and inflammation. The inflammatory response is slightly higher in women; however, there are no sex differences in their functional behavior. There is a probable relationship between the molecular marker of atrial dysfunction NT-proBNP and worse functional outcome in women, and the connection seems to be more important in cardioembolic stroke patients. In patients wi...

Multimodal Optical Diagnostics of the Microhaemodynamics in Upper and Lower Limbs
Conclusion The use of optical non-invasive diagnostic methods has a great potential for the detection of concomitant microcirculation disorders in patients with rheumatic diseases and diabetes. In this review, it was shown that the use of laser Doppler flowmetry, optical tissue oximetry and fluorescence spectroscopy together or separately may have important diagnostic value for the detection of violations, assessment of their severity, as well as for the analysis of the effectiveness of the therapy. The joint application of the considered technologies with the methods of machine learning (discriminant analysis) can be use...

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...

Fool Me Once: An Uncommon Presentation of PE
​BY FREDDIE IRIZARRY-DELGADO; VAROON KAKAIYA; & AHMED RAZIUDDIN, MDAn 86-year-old African-American woman was brought to the ED by her daughter after two days of nutritional neglect, abdominal pain, and altered mental status. Her daughter said her mother felt lightheaded, appeared dehydrated, and vomited nonbilious watery fluid once. The patient had a history of diabetes mellitus type 2, DVT/PE, dementia, and early signs of parkinsonism.Her vital signs were remarkable only for tachypnea (24 bpm). Her troponin I was markedly elevated at 1.7 ng/mL. A D-dimer was ordered because of her history of unprovoked DVT/PE, and i...
