Increased arterial pulsatility and progression of single subcortical infarction
ConclusionsHigher pulsatility was associated with progression in lacunar infarction. PI measured by transcranial Doppler sonography might reflect downstream arterial resistance and vascular/paravascular perfusion status and be a possible indicator of stroke progression.Key Points•Higher pulsatility index was observed in progression group of lacunar infarction patients.•Higher pulsatility index seemed to be associated with progression in lacunar infarction patients.•Differences in the factors associated with stroke progression suggest different underlying pathophysiologies.

Neurorestorative Responses to Delayed Human Mesenchymal Stromal Cells Treatment of Stroke in Type 2 Diabetic Rats Basic Sciences
Conclusions—In T2DM stroke rats, delayed hMSC treatment significantly improves neurological functional outcome and increases neurorestorative effects and M2 macrophage polarization. Increasing brain platelet-derived growth factor expression may contribute to hMSC-induced neurorestoration.

Linagliptin treatment improves cerebrovascular function and remodeling and restores reduced cerebral perfusion in Type 2 diabetes
In this study, we hypothesized that DPP-IV inhibition with linagliptin would improve impaired cerebral perfusion in diabetic rats, as well as improve insulin-induced cerebrovascular relaxation and reverse pathological cerebrovascular remodeling. We further postulated that these changes would lead to a subsequent improvement of cognitive function. Male Type-2 diabetic and nondiabetic Goto-Kakizaki rats were treated with linagliptin for 4 wk, and blood glucose and DPP-IV plasma levels were assessed. Cerebral perfusion was assessed after treatment using laser-Doppler imaging, and dose response to insulin (10–13 M–...

Perfusion-Weighted MRI Parameters for Prediction of Early Progressive Infarction in Middle Cerebral Artery Occlusion.
CONCLUSION: The incidence of EPI is considerable in patients with acute MCA territory infarction caused by MCA occlusion. We suggest that rCBV ratio is a useful neuro-imaging parameter to predict EPI. PMID: 27446514 [PubMed]

Preeclampsia and health risks later in life: an immunological link
Abstract Pregnancy represents a period of physiological stress, and although this stress is experienced for a very modest portion of life, it is now recognized as a window to women’s future health, often by unmasking predispositions to conditions that only become symptomatic later in life. In normal pregnancy, the mother experiences mild metabolic syndrome-like condition through week 20 of gestation. A pronounced phenotype of metabolic syndrome may program pregnancy complications such as preeclampsia. Preeclampsia is a serious complication with a myriad of manifestations for mother and offspring. This pregnancy ...

Assessment of myocardial metabolic flexibility and work efficiency in human type 2 diabetes using 16-18Ffluoro-4-thiapalmitate, a novel PET fatty acid tracer
Altered myocardial fuel selection likely underlies cardiac disease risk in diabetes, affecting oxygen demand and myocardial metabolic flexibility. We investigated myocardial fuel selection and metabolic flexibility in human type 2 diabetes mellitus (T2DM), using positron emission tomography to measure rates of myocardial fatty acid oxidation {16-[18F]fluoro-4-thia-palmitate (FTP)} and myocardial perfusion and total oxidation ([11C]acetate). Participants underwent paired studies under fasting conditions, comparing 3-h insulin + glucose euglycemic clamp conditions (120 mU·m–2·min–1) to 3-h saline in...

Impact of clinical factors and surgical techniques on early outcome of patients treated with frozen elephant trunk technique by using EVITA open stent-graft: results of a multicentre study AORTIC SURGERY
CONCLUSIONS Techniques for faster arch replacement and controlled FET placement should be considered in order to reduce the early mortality and neurological complications after FET surgery. For distal aortic lesions, a two-staged approach is suggested, rather than the FET landing lower than T10.

P-006 evaluation of baseline ct aspects and admission neutrophil-lymphocyte ratio in perfusion-guided selected ica/mca stroke patients for endovascular reperfusion therapy
ConclusionsIn our cohort, baseline CT ASPECTS inversely correlated with admission NLR in anterior circulation AIS patients who had favorable perfusion imaging profile for IA reperfusion therapy. Additionally, in this subgroup of patients, NLR of 5 or less discriminated favorable from unfavorable ASPECTS.DisclosuresA. Honarmand: None. A. Shaibani: None. F. Syed: None. A. Elmokadem: None. M.

P-016 role of balloon guiding catheter in mechanical thrombectomy using stentretrivers subgroup analysis of swift prime
ConclusionBGC use in the SWIFT PRIME cohort of patients treated with rTPA and mechanical thrombectomy with Solitaire demonstrated significantly lower infarct size and higher reperfusion rates at 27 h. Overall procedure times were shorter for BGC group. These findings suggest that there is likely benefit from use of BGC when treating AIS with mechanical thrombectomy; however, randomized trials are required to confirm this finding.Abstract P-016 Table 1Distribution of variables among BGC and no BGC group Characteristic No BGC BGC Total p-value Number394887Age (years)61.8 ± 13.566.8 ± 11.764.6 ± 12....
