Background and aims: Fast-track care have been proved to reduce the shortterm risk of stroke after transient ischemic attack (TIA). We aimed to investigate stroke risk and to characterize short- and long-term stroke predictors in a large cohort of TIA patients undergoing fast-track management. Methods: Prospective study, enrolling consecutive TIA patients admitted to a Northern Italy emergency department from August 2010 to December 2017. All patients underwent fast-track care within 24  h of admission. The primary outcome was defined as the first stroke recurrence at 90  days, 12 and 60  months after TIA. Stroke incidence with 95% confidence interval (CI) at each timepoint was calculated using Poisson regression. Predictors of stroke recurrence were evaluated with Cox regression analysis. The number needed to treat (NNT) of fast-track care in preventing 90-day stroke recurrence in respect to the estimates based on baseline ABCD2 score was also calculated. Results: We enrolled 1,035 patients (54.2% males). Stroke incidence was low throughout the follow-up with rates of 2.2% [95% CI 1.4–3.3%] at 90 days, 2.9% [95% CI 1.9–4.2%] at 12 months and 7.1% [95% CI 5.4–9.0%] at 60 months. Multiple TIA, speech disturbances and presence of ischemic lesion at neuroimaging predicted stroke recurrence at each timepoint. Male sex and increasing age predicted 90-day and 60-month stroke risk, respectively. Hypertension was associated with higher 12-month and 60-month stroke risk. No specific TIA etiology predicted higher stroke risk throughout the followup. The NNT for fast-track care in preventing 90-day stroke was 14.5 [95% CI 11.3–20.4] in the overall cohort and 6.8 [95% CI 4.6–13.5] in patients with baseline ABCD2 of 6 to 7. Conclusion: Our findings support the effectiveness of fast-track care in preventing both short- and long-term stroke recurrence after TIA. Particular effort should be made to identify and monitor patients with baseline predictors of higher stroke risk, which may vary according to follow-up duration. [ABSTRACT FROM AUTHOR]

Introduction: Features and prognosis of capsular warning syndrome (CWS) have been poorly investigated prospectively. Aims: The study aimed to characterize CWS clinical features, risk profile, short- and long-term prognosis, among a large TIA cohort. Methods: Prospective cohort study of consecutive TIAs was conducted from August 1, 2010, to December 31, 2017. Demographic and clinical characteristics, risk profile, primary (stroke and composite outcome) and secondary (TIA recurrence, cerebral hemorrhage, new onset atrial fibrillation) outcomes were compared between CWS, lacunar (L), and nonlacunar (NL) TIAs. Results: 1,035 patients (33 CWS, 189 L-TIAs, 813 NL-TIAs) were enrolled. Newly diagnosed (ND) hypertension, hypercholesterolemia, cigarette smoking, and leukoaraiosis were independent risk factors of CWS (p < 0.05). CWS showed the highest stroke (30.3% vs. 0.5% and 1.5% for L-TIAs and NL-TIAs, respectively) and composite outcome risk at follow-up (p < 0.001), but better 3-month post-stroke prognosis (mRS 0–2 90.0% vs. 36.8%; p = 0.002). CWS-related stroke mostly occurred <48 h (80.0%) and had a small vessel occlusion etiology (100%), affecting more often the internal capsule (60.0%). Dual antiplatelet therapy (DAPT) versus single antiplatelet therapy was associated with lower 3-month cumulative stroke incidence (12.5% vs. 57.1%; p = 0.010). Intravenous thrombolysis (IVT) showed similar 3-month efficacy and safety in strokes after TIAs groups (median mRS 0, IQR 0–1; p = 0.323). Conclusions: CWS is associated with higher stroke risk and better functional prognosis than L- and NL-TIAs. CWS risk profile is consistent with severe small vessel disease, and ND hypertension could represent a major risk factor. DAPT and IVT seem effective and safe in preventing and treating stroke following CWS. [ABSTRACT FROM AUTHOR]

The objective of these Guidelines was to revise and update the previous 2016 Italian Guidelines on Abdominal Aortic Aneurysm Disease, in accordance with the National Guidelines System (SNLG), to guide every practitioner toward the most correct management pathway for this pathology. The methodology applied in this update was the GRADE-SIGN version methodology, following the instructions of the AGREE quality of reporting checklist as well. The first methodological step was the formulation of clinical questions structured according to the PICO (Population, Intervention, Comparison, Outcome) model according to which the Recommendations were issued. Then, systematic reviews of the Literature were carried out for each PICO question or for homogeneous groups of questions, followed by the selection of the articles and the assessment of the methodological quality for each of them using qualitative checklists. Finally, a Considered Judgment form was filled in for each clinical question, in which the features of the evidence as a whole are assessed to establish the transition from the level of evidence to the direction and strength of the recommendations. These guidelines outline the correct management of patients with abdominal aortic aneurysm in terms of screening and surveillance. Medical management and indication for surgery are discussed, as well as preoperative assessment regarding patients' background and surgical risk evaluation. Once the indication for surgery has been established, the options for traditional open and endovascular surgery are described and compared, focusing specifically on patients with ruptured abdominal aortic aneurysms as well. Finally, indications for early and late postoperative follow-up are explained. The most recent evidence in the Literature has been able to confirm and possibly modify the previous recommendations updating them, likewise to propose new recommendations on prospectively relevant topics.
