- Abstract
Background: Among asymptomatic patients with severe carotid artery stenosis but no recent stroke or transient cerebral ischaemia, either carotid artery stenting (CAS) or carotid endarterectomy (CEA) can restore patency and reduce long-term stroke risks. However, from recent national registry data, each option causes about 1% procedural risk of disabling stroke or death. Comparison of their long-term protective effects requires large-scale randomised evidence. Methods: ACST-2 is an international multicentre randomised trial of CAS versus CEA among asymptomatic patients with severe stenosis thought to require intervention, interpreted with all other relevant trials. Patients were eligible if they had severe unilateral or bilateral carotid artery stenosis and both doctor and patient agreed that a carotid procedure should be undertaken, but they were substantially uncertain which one to choose. Patients were randomly allocated to CAS or CEA and followed up at 1 month and then annually, for a mean 5 years. Procedural events were those within 30 days of the intervention. Intention-to-treat analyses are provided. Analyses including procedural hazards use tabular methods. Analyses and meta-analyses of non-procedural strokes use Kaplan-Meier and log-rank methods. The trial is registered with the ISRCTN registry, ISRCTN21144362. Findings: Between Jan 15, 2008, and Dec 31, 2020, 3625 patients in 130 centres were randomly allocated, 1811 to CAS and 1814 to CEA, with good compliance, good medical therapy and a mean 5 years of follow-up. Overall, 1% had disabling stroke or death procedurally (15 allocated to CAS and 18 to CEA) and 2% had non-disabling procedural stroke (48 allocated to CAS and 29 to CEA). Kaplan-Meier estimates of 5-year non-procedural stroke were 2·5% in each group for fatal or disabling stroke, and 5·3% with CAS versus 4·5% with CEA for any stroke (rate ratio [RR] 1·16, 95% CI 0·86–1·57; p=0·33). Combining RRs for any non-procedural stroke in all CAS versus CEA

Objectives: ACST-2 is currently the largest trial ever conducted to compare carotid artery stenting (CAS) with carotid endarterectomy (CEA) in patients with severe asymptomatic carotid stenosis requiring revascularization. Methods: Patients are entered into ACST-2 when revascularization is felt to be clearly indicated, when CEA and CAS are both possible, but where there is substantial uncertainty as to which is most appropriate. Trial surgeons and interventionalists are expected to use their usual techniques and CE-approved devices. We report baseline characteristics and blinded combined interim results for 30-day mortality and major morbidity for 986 patients in the ongoing trial up to September 2012. Results: A total of 986 patients (687 men, 299 women), mean age 68.7 years (SD ± 8.1) were randomized equally to CEA or CAS. Most (96%) had ipsilateral stenosis of 70-99% (median 80%) with contralateral stenoses of 50-99% in 30% and contralateral occlusion in 8%. Patients were on appropriate medical treatment. For 691 patients undergoing intervention with at least 1-month follow-up and Rankin scoring at 6 months for any stroke, the overall serious cardiovascular event rate of periprocedural (within 30 days) disabling stroke, fatal myocardial infarction, and death at 30 days was 1.0%. Conclusions: Early ACST-2 results suggest contemporary carotid intervention for asymptomatic stenosis has a low risk of serious morbidity and mortality, on par with other recent trials. The trial continues to recruit, to monitor periprocedural events and all types of stroke, aiming to randomize up to 5,000 patients to determine any differential outcomes between interventions.

Contains fulltext : 88112.pdf (Publisher’s version ) (Closed access) BACKGROUND: Stents are an alternative treatment to carotid endarterectomy for symptomatic carotid stenosis, but previous trials have not established equivalent safety and efficacy. We compared the safety of carotid artery stenting with that of carotid endarterectomy. METHODS: The International Carotid Stenting Study (ICSS) is a multicentre, international, randomised controlled trial with blinded adjudication of outcomes. Patients with recently symptomatic carotid artery stenosis were randomly assigned in a 1:1 ratio to receive carotid artery stenting or carotid endarterectomy. Randomisation was by telephone call or fax to a central computerised service and was stratified by centre with minimisation for sex, age, contralateral occlusion, and side of the randomised artery. Patients and investigators were not masked to treatment assignment. Patients were followed up by independent clinicians not directly involved in delivering the randomised treatment. The primary outcome measure of the trial is the 3-year rate of fatal or disabling stroke in any territory, which has not been analysed yet. The main outcome measure for the interim safety analysis was the 120-day rate of stroke, death, or procedural myocardial infarction. Analysis was by intention to treat (ITT). This study is registered, number ISRCTN25337470. FINDINGS: The trial enrolled 1713 patients (stenting group, n=855; endarterectomy group, n=858). Two patients in the stenting group and one in the endarterectomy group withdrew immediately after randomisation, and were not included in the ITT analysis. Between randomisation and 120 days, there were 34 (Kaplan-Meier estimate 4.0%) events of disabling stroke or death in the stenting group compared with 27 (3.2%) events in the endarterectomy group (hazard ratio [HR] 1.28, 95% CI 0.77-2.11). The incidence of stroke, death, or procedural myocardial infarction was 8.5% in the stenting group compared with 5.2% in the endarterectomy group (72 vs 44 events; HR 1.69, 1.16-2.45, p=0.006). Risks of any stroke (65 vs 35 events; HR 1.92, 1.27-2.89) and all-cause death (19 vs seven events; HR 2.76, 1.16-6.56) were higher in the stenting group than in the endarterectomy group. Three procedural myocardial infarctions were recorded in the stenting group, all of which were fatal, compared with four, all non-fatal, in the endarterectomy group. There was one event of cranial nerve palsy in the stenting group compared with 45 in the endarterectomy group. There were also fewer haematomas of any severity in the stenting group than in the endarterectomy group (31 vs 50 events; p=0.0197). INTERPRETATION: Completion of long-term follow-up is needed to establish the efficacy of carotid artery stenting compared with endarterectomy. In the meantime, carotid endarterectomy should remain the treatment of choice for patients suitable for surgery.

PURPOSE: Carotid artery stent placement may be limited by the embolization of atheromatous material. We evaluated the safety and feasibility of the Medtronic Self-Expanding Carotid Stent (Exponent) in combination with the Medtronic Interceptor Carotid Filter System for the treatment of carotid stenosis among patients at high risk for carotid endarterectomy. METHODS: Patients at high risk for carotid endarterectomy but amenable to percutaneous treatment with stent placement were enrolled. Clinical follow-up was performed at 30 days and 6 and 12 months postprocedure. The National Institutes of Health Stroke Scale was assessed before and within 3 days postprocedure and at 30 days and 6 months postprocedure. Angiography was performed pre- and postprocedure, and carotid duplex scans were performed at baseline and at 30 days and 6 months. RESULTS: Fifty-two carotid procedures were performed in 51 patients (mean age, 69 years; 84% of patients were men). The major adverse event (MAE) rate (death, stroke, and myocardial infarction [MI]) at 30 days was 5.9%: 2 strokes and a single death from periprocedural MI. MAE rates after 6 and 12 months were 5.9% and 11.8%, respectively. The delivery success rate was 94.2% (49/52) for the Interceptor Filter System and 95.9% (47/49) for the Exponent Stent. The mean diameter stenosis of the target lesion was reduced from 62.4% preprocedure to 21.2% postprocedure. CONCLUSION: High delivery success rates were achieved with a low rate of MAE (death, stroke, or MI) in a high-risk population. Treatment of carotid artery disease with the Exponent Carotid Stent combined with distal protection from the Interceptor Filter System is effective and safe.

- Abstract
Background: The anatomy of carotid stenosis may influence the outcome of endovascular treatment or carotid endarterectomy. Whether anatomy favors one treatment over the other in terms of safety or efficacy has not been investigated in randomized trials. Methods: In 414 patients with mostly symptomatic carotid stenosis randomized to endovascular treatment (angioplasty or stenting; n=213) or carotid endarterectomy (n=211) in the Carotid and Vertebral Artery Transluminal Angioplasty Study (CAVATAS), the degree and length of stenosis and plaque surface irregularity were assessed on baseline intraarterial angiography. Outcome measures were stroke or death occurring between randomization and 30 days after treatment, and ipsilateral stroke and restenosis =50% during follow-up. Results: Carotid stenosis longer than 0·65 times the common carotid artery diameter was associated with increased risk of peri-procedural stroke or death after both endovascular treatment [odds ratio 2·79 (1·17-6·65), P=0·02] and carotid endarterectomy [2·43 (1·03-5·73), P=0·04], and with increased long-term risk of restenosis in endovascular treatment [hazard ratio 1·68 (1·12-2·53), P=0·01]. The excess in restenosis after endovascular treatment compared with carotid endarterectomy was significantly greater in patients with long stenosis than with short stenosis at baseline (interaction P=0·003). Results remained significant after multivariate adjustment. No associations were found for degree of stenosis and plaque surface. Conclusions: Increasing stenosis length is an independent risk factor for peri-procedural stroke or death in endovascular treatment and carotid endarterectomy, without favoring one treatment over the other. However, the excess restenosis rate after endovascular treatment compared with carotid endarterectomy increases with longer stenosis at baseline. Stenosis length merits further investigation in carotid revascularisation trials. © 2013 The Authors. International Journal of Strok

- Abstract
Background: Stents are an alternative treatment to carotid endarterectomy for symptomatic carotid stenosis, but previous trials have not established equivalent safety and efficacy. We compared the safety of carotid artery stenting with that of carotid endarterectomy. Methods: The International Carotid Stenting Study (ICSS) is a multicentre, international, randomised controlled trial with blinded adjudication of outcomes. Patients with recently symptomatic carotid artery stenosis were randomly assigned in a 1:1 ratio to receive carotid artery stenting or carotid endarterectomy. Randomisation was by telephone call or fax to a central computerised service and was stratified by centre with minimisation for sex, age, contralateral occlusion, and side of the randomised artery. Patients and investigators were not masked to treatment assignment. Patients were followed up by independent clinicians not directly involved in delivering the randomised treatment. The primary outcome measure of the trial is the 3-year rate of fatal or disabling stroke in any territory, which has not been analysed yet. The main outcome measure for the interim safety analysis was the 120-day rate of stroke, death, or procedural myocardial infarction. Analysis was by intention to treat (ITT). This study is registered, number ISRCTN25337470. Findings: The trial enrolled 1713 patients (stenting group, n=855; endarterectomy group, n=858). Two patients in the stenting group and one in the endarterectomy group withdrew immediately after randomisation, and were not included in the ITT analysis. Between randomisation and 120 days, there were 34 (Kaplan-Meier estimate 4·0%) events of disabling stroke or death in the stenting group compared with 27 (3·2%) events in the endarterectomy group (hazard ratio [HR] 1·28, 95% CI 0·77-2·11). The incidence of stroke, death, or procedural myocardial infarction was 8·5% in the stenting group compared with 5·2% in the endarterectomy group (72 vs 44 events; HR 1·69, 1·16-2

The management of unruptured intracranial aneurysms requires knowledge of the natural history of these lesions and the risks of repairing them.A total of 2621 patients at 53 participating centers in the United States, Canada, and Europe were enrolled in the study, which had retrospective and prospective components. In the retrospective component, we assessed the natural history of unruptured intracranial aneurysms in 1449 patients with 1937 unruptured intracranial aneurysms; 727 of the patients had no history of subarachnoid hemorrhage from a different aneurysm (group 1), and 722 had a history of subarachnoid hemorrhage from a different aneurysm that had been repaired successfully (group 2). In the prospective component, we assessed treatment-related morbidity and mortality in 1172 patients with newly diagnosed unruptured intracranial aneurysms.In group 1, the cumulative rate of rupture of aneurysms that were less than 10 mm in diameter at diagnosis was less than 0.05 percent per year, and in group 2, the rate was approximately 11 times as high (0.5 percent per year). The rupture rate of aneurysms that were 10 mm or more in diameter was less than 1 percent per year in both groups, but in group 1, the rate was 6 percent the first year for giant aneurysms (or =25 mm in diameter). The size and location of the aneurysm were independent predictors of rupture. The overall rate of surgery-related morbidity and mortality was 17.5 percent in group 1 and 13.6 percent in group 2 at 30 days and was 15.7 percent and 13.1 percent, respectively, at 1 year. Age independently predicted surgical outcome.The likelihood of rupture of unruptured intracranial aneurysms that were less than 10 mm in diameter was exceedingly low among patients in group 1 and was substantially higher among those in group 2. The risk of morbidity and mortality related to surgery greatly exceeded the 7.5-year risk of rupture among patients in group 1 with unruptured intracranial aneurysms smaller than 10 mm in diameter.

Aneurysms of the lenticulostriatal perforating arteries are rare and either involve the middle cerebral artery-perforator junction or are located distally in basal ganglia. We describe a rare ruptured fusiform lenticulostriatal perforating artery aneurysm arising from a proximal M2 MCA branch, discerned on superselective microcatheter angiography, presenting solely with subarachnoid hemorrhage (SAH). A 50-year-old previously healthy man presented with diffuse SAH and negative CT angiogram. Cerebral angio gram demonstrated a 2 mm fusiform aneurysm presumably arising from the right lateral lenticulostriate perforator but the exact origin of the perforator was unclear. Superselective angiography was required to precisely delineate the aneurysm and its vessel of origin and directly influenced treatment planning (surgical trapping). Superselective microcatheter angiography provides both an option for endovascular therapy as well as more accurate delineation for surgical planning for these rare aneurysms. [ABSTRACT FROM AUTHOR]

Despite controversy surrounding the concept of mild head injury (MHI), it is becoming evident that even a head trauma termed 'mild' may result in significant behavioural sequelae. The present study was an attempt at documenting structural cerebral damage, by way of computerized tomography, in a group of patients having suffered a MHI as defined by the Glasgow Coma Scale (GCS) score. A 1-year retrospective chart review identified 80 MHI patients who presented to the Emergency department of a lead hospital for trauma. Sixty-six per cent of these MHI patients were scanned. Evidence of intracranial abnormalities was obtained in 31% of the overall sample. Patients with a lower GCS score had a higher percentage of abnormal scans than those with a GCS score of either 14 or 15. The present findings suggest that a MHI can be associated with significant morbidity, and that a MHI group does not constitute a homogeneous pool of patients. [ABSTRACT FROM AUTHOR]

Methods In acute ischemic stroke, good outcome following successful recanalization is time dependent. In patients undergoing endovascular therapy at our institution, recanalization times with the Solitaire stent were retrospectively evaluated to assess for the presence of a learning curve in achieving rapid recanalization. Methods We reviewed patients who presented to our stroke center and achieved successful recanalization with the Solitaire stent exclusively. Time intervals were calculated (CT to angiography arrival, angiography arrival to groin puncture, groin puncture to first deployment, and deployment to recanalization) from time stamped images and angiography records. Patients were divided into three sequential groups, with overall CT to recanalization time and subdivided time intervals compared. Results 83 patients were treated with the Solitaire stent from May 2009 to February 2012. Recanalization (Thrombolyis in Cerebral Infarction score 2A) occurred in 75 (90.4%) patients. CT to recanalization demonstrated significant improvement over time, which was greatest between the first 25 and the most recent 25 cases (161-94 min; p<0.01). The maximal contribution to this was from improvements in first stent deployment to recanalization time (p=0.001 between the first and third groups), with modest contributions from moving patients from CT to the angiography suite faster (p=0.02 between the first and third groups) and from groin puncture to first stent deployment (p=0.02 between the first and third groups). Conclusions There is a learning curve involved in the efficient use of the Solitaire stent in endovascular acute stroke therapy. Along with improvements in patient transfer to angiography and improved efficiency with intracranial access, mastering this device contributed significantly towards reducing recanalization times.

P39 Background: Hyperacute neurovascular imaging has great potential to help clinicians better tailor stroke therapy. Future decisions to use intravenous and/or intra-arterial lytics may depend on site of MCA occlusion. TCD has not been seriously considered as such a technique because of the misconception TCD is too operator dependent and not reliable. We evaluated if our acute stroke TCD service could accurately and reliably identify MCA occlusion. Methods: A series of acute stroke patients underwent TCD examination by 1 of 3 stroke physicians or 1 stroke nurse. MRA was also performed at a time closely corresponding to TCD exam. Blind to MRA findings and patient info except symptom side, all 4 sonographers independently interpreted the TCD exam for presence of MCA occlusion using previously established TCD criteria and evaluated TIBI flow grades (5 normal waveform, 4 stenotic, 3 dampened, 2 blunted, 1 minimal, 0 absent) at 65, 55, 45 mm MCA depths. This result was compared to blinded neuroradiologists MRA interpretation for M1-MCA and distal MCA occlusion. Results: 37 cases compared. Mean age 67, median baseline NIHSS 8. Median symptom onset to TCD 5.9 hours and MRA 6.3 hours. Median time between TCD and MRA 1.3 hours. TPA treatment preceded or occurred during TCD or MRA imaging in 27% of cases. MRA identified 19 MCA occlusion (12 M1-MCA, 7 distal MCA) and 18 no MCA occlusion. Comparing all sonographer TCD interpretations (n=148) with MRA the sensitivity, specificity, PPV, NPV for MCA occlusion was: 82%, 81%, 82%, 81% respectively. Intraclass correlation coefficent for TIBI flow grades at prox, mid, distal MCA depths was : 0.73,0.84,0.83. Median TIBI scores at these 3 MCA depths respectively were: 5,5,5 when no MCA occlusion on MRA, 3,3,3 if distal MCA occlusion and 2,2,2 if M1-MCA occlusion. Conclusion: TCD showed good accuracy at identifying MCA occlusion compared to MRA when TCD was performed and interpreted by a stroke clinician/nurse. TIBI flow grades were reliably identified and appear potentially useful to discriminate between normal MCA, and proximal or distal MCA occlusion. TCD is a useful bedside tool that could aid future stroke treatment.

Retinal artery occlusion represents a medical emergency with poor prognosis for visual recovery. Spontaneous improvement is estimated to occur in less than 15% of central retinal artery occlusion (CRAO) cases and conventional treatments have provided only limited benefit. Intra-arterial thrombolysis has been reported as a potentially efficacious and safe treatment.We performed a retrospective chart review of all retinal artery occlusion cases treated with intra-arterial recombinant tissue-type plasminogen activator (rtPA) from January 1998 to May 2004. Patients received Goldmann perimetry visual field testing at a variable interval following the procedure (2 days-2.5 years). Visual acuity (VA) was re-assessed in May 2004.Eight cases (59-77 years) were treated for CRAO, 6-18 hours post-onset with intra-arterial rtPA (10-20 mg over 15-60 minutes); one case of branch occlusion (BRAO) was treated with 30 mg rtPA over 75 minutes, 12 hours post-onset. Among the six patients with CRAO assessed in clinic, three experienced improvement in VA by two or more gradations (Snellen lines); three improved by one gradation. However, none achieved a final VA better than 20/300. The case of branch occlusion improved to a VA of 20/20. All patients had residual monocular field defects.Our findings reveal a limited benefit for intra-arterial tPA compared to the rate of spontaneous improvement and conventional forms of therapy for retinal artery occlusion.

- Abstract
Background Stents are an alternative treatment to carotid endarterectomy for symptomatic carotid stenosis, but previous trials have not established equivalent safety and efficacy. We compared the safety of carotid artery stenting with that of carotid endarterectomy.Methods The International Carotid Stenting Study (ICSS) is a multicentre, international, randomised controlled trial with blinded adjudication of outcomes. Patients with recently symptomatic carotid artery stenosis were randomly assigned in a 1:1 ratio to receive carotid artery stenting or carotid endarterectomy. Randomisation was by telephone call or fax to a central computerised service and was stratified by centre with minimisation for sex, age, contralateral occlusion, and side of the randomised artery. Patients and investigators were not masked to treatment assignment. Patients were followed up by independent clinicians not directly involved in delivering the randomised treatment. The primary outcome measure of the trial is the 3-year rate of fatal or disabling stroke in any territory, which has not been analysed yet. The main outcome measure for the interim safety analysis was the 120-day rate of stroke, death, or procedural myocardial infarction. Analysis was by intention to treat (ITT). This study is registered, number ISRCTN25337470.Findings The trial enrolled 1713 patients (stenting group, n=855; endarterectomy group, n=858). Two patients in the stenting group and one in the endarterectomy group withdrew immediately after randomisation, and were not included in the ITT analysis. Between randomisation and 120 days, there were 34 (Kaplan-Meier estimate 4.0%) events of disabling stroke or death in the stenting group compared with 27 (3.2%) events in the endarterectomy group (hazard ratio [HR] 1.28, 95% CI 0.77-2.11). The incidence of stroke, death, or procedural myocardial infarction was 8.5% in the stenting group compared with 5.2% in the endarterectomy group (72 vs 44 events; HR 1.69, 1.16-2.45

Microcapillaries are inherently fluidic sensing platforms that can, under appropriate conditions, support lasing. We propose and demonstrate a lasing microcapillary sensor based on "star" and "triangle" interferences arising from reflection and refraction at the inner and outer microcapillary walls. These interferences lead to distinct modal trajectories that sample the channel medium inside the microcavity structure. Both star and triangle resonances are therefore sensitive to the nature of the channel medium, yielding theoretical and experimental sensitivities significantly exceeding those found for sensors based on conventional whispering-gallery modes. Additional enhancement can be achieved because the two main resonance families shift in an opposite sense, yielding a differential sensitivity that can reach several thousand nanometers per refractive index "unit." These devices represent a robust, yet easily fabricated optical sensor and capillary-based lasing system for microfluidic sensing. Refereed/Peer-reviewed

- Abstract
Objectives: The goal of this study was to develop a systematic method to identify and classify different types of communication failures leading to patient safety events. We aimed to develop a taxonomy code sheet for identifying communication errors and provide a framework tool to classify the communication error types., Methods: This observational study used the Delphi method to develop a taxonomy code sheet for identifying communication errors reported in the Veterans Health Administration patient safety databases between April 2018 and March 2021. We also used Natural Language Processing to create a framework tool to classify the 9 types of communication errors using this taxonomy. Finally, analysis was done to identify affected clinical locations., Results: We identified 9 types of communication failures that impacted clinical outcomes using the taxonomy code sheet developed. The top 3 errors were related to nonadherence to facility standard operating procedures (993, 37.6%), followed by written errors (e.g., unclear documentation or not using plain language) (587, 22.3%) and no communication (347, 13.2%). The remaining categories of communication types are electronic (253, 9.6%), verbal (205, 7.8%), hand-off (124, 4.7%), visual (76, 2.9%), listening (41, 1.6%), and nonverbal (12, 0.5%). A cognitive aide was developed to demonstrate the step-by-step method for using the framework tool to classify the communication errors., Conclusions: The cognitive aide and the framework tool developed in this study can be used in any healthcare setting to identify and classify communication failures and mitigate potential risks contributing to safety events., Competing Interests: The authors disclose no conflict of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

- Abstract
Objectives: Eighteen years of patient safety (PS) and root cause analysis reports for hemodialysis bleeding events and deaths in the Veterans Health Administration were analyzed with dual purpose: to determine the impact of a 2008 Veterans Health Administration Patient Safety Advisory on event reporting rates and to identify actions to mitigate risk and inform policy., Methods: From 2002 to 2020, 281 bleeding events (248 PS reports and 33 root cause analyses) including 14 deaths during hemodialysis treatments were identified. Events were characterized by the type of vascular access, patient mental status, and whether the access site was visible or obscured from view by staff., Results: Of the 281 bleeding events reviewed, 188 (67%) were unwitnessed and 54 (19%) were associated with an alteration in mental status. Most deaths (n = 11; 79%) were associated with central venous catheter access. Root cause analyses reported 83 root causes, of which 33% identified physical barriers to direct observation or an equipment issue.Action plans addressed policy/procedures (30%), training/education (20%), and changes to environment/equipment (19%). Patient Safety Advisory publication was associated with a significant increase in low-harm PS reports, from 9 to 18 per year (P = 0.001)., Conclusions: Bleeding events during hemodialysis treatments occur and may be fatal. Heightened vigilance is required when physical barriers obscure continuous direct observation, the patient exhibits an altered mental status, and vascular access is through a central venous catheter.Provider staff should consider a safety checklist and training on equipment operation. Patient Safety Advisory publication was associated with increased low-harm event reporting., Competing Interests: The authors disclose no conflict of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

- Abstract
Background: Cardiac telemetry downtime may be planned or unplanned, causing a disruption in telemetry services with a potential to impact patient safety., Problem: Many cardiac telemetry units in the Veterans Health Administration (VHA) have contingency plans that do not adequately address telemetry downtime., Approach: This is a retrospective quality improvement analysis of VHA-reported cardiac telemetry downtime events from October 1, 2014, to Mar 31, 2020., Outcomes: Of 98 events, no patient harm was reported; 13% (n = 13) were planned downtime, 82% (n = 80) were unplanned downtime, 18% (n = 18) reported contingency plan use, 78% (n = 76) did not specify contingency plan use, and 32% (n = 31) reported events lasting 31 minutes to 6 hours in duration., Conclusions: The majority of reported cardiac telemetry downtime events were unplanned and without documented contingency plans. A robust contingency plan with defined staff roles and responsibilities will serve to lessen anxiety during downtimes and mitigate potential risk of patient harm., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

- Abstract
Objectives: The Veterans Health Administration maintains national patient safety event reporting and root cause analysis (RCA) databases. These were reviewed to understand the prevalence of and provide insight into patient misidentification. The results were compared with a high-reliability health care framework., Methods: We reviewed patient safety reports and RCA reports to identify and categorize patient identification-related events from October 1, 2016, to September 30, 2018. We analyzed 3232 patient safety reports and 67 RCAs, aggregated the findings, and compared them against The Joint Commission's High Reliability Health Care Maturity Model., Results: Patient misidentification occurred in both inpatient and outpatient settings, for which the ratio of adverse events to close calls was similar. The ratio of adverse events to close calls varied for specific care areas. The most common RCA event characteristic was Two identifiers not used (39%). The most common failure mode was Procedure performed on wrong patient (31%). Issues related to policy and processes accounted for 42% of the root causes. Actions taken were primarily related to policy, process, and staff training/education (56%); these actions were rated as effective by the reporting facilities., Conclusions: Patient misidentification is prevalent in both the inpatient and outpatient settings. However, specific care areas reported more close calls, an indicator of good safety culture. There were associations between policy and process issues, consistent use of 2 identifiers, and misidentification events. This review provides insight from the Veterans Health Administration national databases that health care institutions can use to improve their systems., Competing Interests: The authors disclose no conflict of interest., (Copyright © 2020 Wolters Kluwer Health, Inc.

- Abstract
Background: Canada began a national reform of its post-graduate medical education training programs to a Competence By Design (CBD) model. Trends from accredited neuroradiology programs from the past 10 years were investigated to inform educators and stakeholders for this process., Methods: A 13-question electronic survey was sent to program directors of all 8 accredited neuroradiology training programs in Canada. Data was requested for each year on the 2008-2019 graduating classes. Questions pertained to program enrolment; program completion; post-training employment; and the sufficiency of 1-year training programs., Results: Response rate was 100%. Over the timeframe studied, the 2-year programs increased in size ( P = 0.007), while the 1-year programs remained steady ( P = 0.27). 12.2% of trainees enrolled in the 2-year program dropped out after 1 year, and were considered 1-year trainees thereafter. A higher proportion of 2-year trainees obtain positions within academic institutions (89.5 vs 67.2%, P = 0.0007), whereas a higher proportion of 1-year trainees obtain positions within non-academic institutions (29.3 vs 8.1%, P = 0.0007). A higher proportion of those with Canadian board certification in diagnostic radiology who completed a 2-year program obtained a position within a Canadian academic institution compared to non-certified 2-year trainees ( P < 0.001). 71.4% of program directors agreed that a 1-year program was sufficient for non-academic staff positions., Conclusion: The length of the training program has significant impact on employment in academic vs non-academic institutions. This information can be used to guide the upcoming CBD initiative for neuroradiology programs.

- Abstract
Luminescent silicon nanoparticles have been widely recognized as an alternative for metal-based quantum dots (QDs) for optoelectronics partly because of the high abundance and biocompatibility of silicon. To date, the broad photoluminescence line width (often >100 nm) of silicon QDs has been a hurdle to achieving competitive spectral purity and incorporating them into light-emitting devices. Herein we report fabrication and testing of straightforward configuration of Fabry-Pérot resonators that incorporates a thin layer of SiQD-polymer hybrid/blend between two reflective silver mirrors; remarkably these devices exhibit up-to-14-fold narrowing of SiQD emission and achieve a spectral bandwidth as narrow as ca. 9 nm. Our polymer-based, SiQD-containing Fabry-Pérot resonators also provide convenient spectral tunability, can be prepared using a variety of polymer hosts and substrates, and enable rigid as well as flexible devices.

- Abstract
Background: Aneurysm recurrence after Pipeline Embolization Device (PED) placement can be caused by oversizing of the stent as well as poor wall apposition, both of which can lead to elongation. The objective of this study was to assess whether a novel parameter for measuring device elongation based on two-dimensional imaging could be predictive for persistent aneurysm filling after treatment with the PED., Methods: A retrospective cohort analysis was initially completed on 41 aneurysms from institution A, examining demographic, aneurysmal, and device measurements. Device measurements, including the ratio of the measured length to the nominal length (ML/NL) of the PED, were taken by reviewers blinded to the primary end point, which was aneurysm occlusion status on 6 month catheter angiogram. Findings were then externally validated against 30 aneurysms (supraclinoid only) from institution B., Results: Data from institution A showed 61% complete aneurysm occlusion at 6 months, and were lower for aneurysms in the supraclinoid region. For supraclinoid aneurysms alone, combined data from both institutions showed higher rates of nonocclusion with aneurysm neck size >4 mm (P = 0.008) and a trend toward significance in aneurysms with a branch vessel (P = 0.051). The mean ML/NL ratio was significantly larger in the nonoccluded group compared with the occluded group at both institution A (ratio, 1.37 versus 1.10; P < 0.001) and institution B (ratio, 1.36 vs. 1.11; P = 0.002)., Conclusions: Our data suggest that a novel parameter based on two-dimensional angiography may serve as a rapid technique to measure device elongation and predict occlusion of supraclinoid aneurysms after PED placement., (Copyright © 2020 Elsevier Inc.

- Abstract
The luminescence dynamics in ensembles of nanocrystals are complicated by a variety of processes, including the size-dependence of the radiative and non-radiative rates in inhomogeneous broadened samples and interparticle interactions. This results in a non-exponential decay, which for the specific case of silicon nanocrystals (SiNCs) has been widely modeled with a Kohlrausch or "stretched exponential" (SE) function. We first derive the population decay function for a luminescence decay following exp[- (t/τ)
β ]. We then compare the distributions and mean times calculated by assuming that either the luminescence decay or the population decay follows this function and show that the results are significantly different for β much below 1. We then apply these two types of SE functions as well as other models to the luminescence decay data from two thermally grown SiNC samples with different mean sizes. The mean lifetimes are strongly dependent on the experimental setup and the chosen fitting model, none of which appears to adequately describe the ensemble decay dynamics. Frequency-resolved spectroscopy (FRS) techniques are then applied to SiNCs in order to extract the lifetime distribution directly. The rate distribution has a half width of ~ 0.5 decades and mainly resembles a somewhat high-frequency-skewed lognormal function. The combination of TRS and FRS methods appear best suited to uncovering the luminescence dynamics of NC materials having a broad emission spectrum.- Published
