Q: Thromboembolic events represent a clinically significant cause of neurological morbidity during the endovascular management of cerebral aneurysms. We have implemented an anti-thromboembolic regimen consisting of pre- and postoperative dual antiplatelet therapy, as well as postoperative anticoagulation using heparin and dextran. The aims of our study were to examine the effect of this regimen on thromboembolic rates during elective aneurysm coiling, and to elucidate risk factors associated with the development of thromboembolic events in this setting.', 'We conducted a retrospective review of patients who underwent elective intracranial aneurysm coiling between January 2005 and February 2012. The primary outcome of interest was the occurrence of a clinically significant peri-procedural thromboembolic event. Secondary outcomes included the occurrence of a central nervous system (CNS) or systemic hemorrhage.', 'During the study period, 312 patients underwent elective aneurysm coiling and six (2\xa0%) thromboembolic events occurred; three (1\xa0%) occurred in the group that received the anti-thromboembolic regimen (261 patients) and three (6\xa0%) occurred in the group that did not receive the regimen (51 patients), resulting in a statistically significant difference (P\u2009=\u20090.024). Both the presence of a hypercoagulable state (P\u2009=\u20090.014) and the lack of the anti-thromboembolic regimen (P\u2009=\u20090.043) were significantly associated with the occurrence of a thromboembolic event.

Q: Evidence regarding the mortality rate after administration of the pandemic influenza A (H1N1) 2009 vaccine on patients with underlying diseases is currently scarce. We conducted a case-control study in Japan to compare the mortality rates of patients with idiopathic interstitial pneumonia after the vaccines were administered and were not administered.', 'Between October 2009 and March 2010, we collected clinical records in Japan and conducted a 1:1 matched case-control study. Patients with idiopathic interstitial pneumonia who died during this period were considered case patients, and those who survived were considered control patients. We determined and compared the proportion of each group that received the pandemic influenza A (H1N1) 2009 vaccine and estimated the odds ratio. Finally, we conducted simulations that compensated for the shortcomings of the study associated with adjusted severity of idiopathic interstitial pneumonia.', 'The case and control groups each comprised of 75 patients with idiopathic interstitial pneumonia. The proportion of patients who received the pandemic influenza A (H1N1) 2009 vaccine was 30.7% and 38.7% for the case and control groups, respectively. During that winter, the crude conditional odds ratio of mortality was 0.63 (95% confidence interval, 0.25-1.47) and the adjusted conditional odds ratio was 1.18 (95% confidence interval, 0.33-4.49); neither was significant. The simulation study showed more accurate conditional odds ratios of 0.63-0.71.

Q: There is increasing evidence linking arterial (mainly aortic) stiffness and type 2 diabetes, a risk factor for arterial stiffness, to cognitive impairment and dementia. However, data on carotid stiffness, which may be especially relevant for cognitive performance, are scarce, and few studies have addressed the interplay between arterial stiffness, type 2 diabetes, and cognitive performance.', "We studied individuals with (n\xa0=\xa0197) and without (n\xa0=\xa0528) type 2 diabetes, who completed a neuropsychological test battery and underwent applanation tonometry and vascular ultrasound to evaluate aortic (i.e. carotid-to-femoral pulse wave velocity) and carotid stiffness (i.e. distensibility, compliance and Young's elastic modulus). Linear regression analyses were performed and adjusted for demographics, vascular risk factors, and depression.", "Overall, our results showed that carotid, but not aortic, stiffness was associated with worse cognitive performance, primarily in the domains of processing speed (standardized regression coefficient for distensibility\xa0-0.083, p\xa0=\xa00.040; compliance\xa0-0.077, p\xa0=\xa00.032) and executive function and attention (distensibility\xa0-0.133, p\xa0=\xa00.001; compliance\xa0-0.090, p\xa0=\xa00.015; Young's elastic modulus\xa0-0.081, p\xa0=\xa00.027). These associations did not differ by diabetes status. The differences in cognitive performance between individuals with and without type 2 diabetes (mean difference in domain scores relative to those without diabetes for free recall memory\xa0-0.23, processing speed\xa0-0.19, executive function and attention\xa0-0.23; all p\xa0≤\xa00.009 and adjusted for demographics, traditional vascular risk factors, and depression) were not substantially altered after additional adjustment for carotid stiffness.
