RESUMO
BACKGROUND: The current mainstays of ischemic stroke treatment include the use of thrombolysis (tissue plasminogen activator [tPA]), urgent carotid endarterectomy (uCEA) or urgent carotid artery stenting (uCAS), and mechanical endovascular reperfusion/thrombectomy (MER). Scarce data describe the presenting stroke severity and neurologic outcomes for these acute ischemic stroke interventions, alone or in combination. The authors hypothesize that patients undergoing carotid interventions experience better functional neurologic outcomes than other stroke interventions. METHODS: A comprehensive stroke center dataset was combined with data for stroke-related procedures, comorbidities, complications, and physician documentation collected from electronic medical record data. A total of 10,975 patient encounter records from January 1, 2015, through July 31, 2021, were retrieved. The presenting stroke severity was determined by vascular/stroke neurologists using the National Institutes of Health Stroke Scale (NIHSS). Functional neurologic outcomes were reported using the modified Rankin scale (mRS) score, which quantifies the degree of neurologic disability. Because mRS values were only available for 3627 encounters in the original dataset, the authors developed a machine learning algorithm to analyze physician documentation and assign an mRS value. After the exclusion and machine learning analysis, a total of 5170 patient encounters were included for statistical analysis. Statistical analyses included the χ2 test, one-way analysis of variance and logistic regression on 30-day complications, stroke severity, and neurologic outcomes. RESULTS: Patients were divided into five cohorts: (1) uCEA or uCAS (n = 189), (2) tPA alone (n = 1053), (3) MER alone (n = 418), (4) tPA + MER (n = 199), and (5) no intervention (n = 3311). Patients undergoing uCEA/uCAS were significantly more likely to be male, smokers, and have a history of peripheral arterial disease compared with other stroke cohorts. The length of stay was shortest for patients who only received tPA or no intervention (6 days), followed by uCEA/uCAS (7.2 days), MER (10.2 days), and tPA + MER (8.8 days) cohorts (P < .001). The 30-day mortality was highest in the MER cohort (12.2%) and lowest in the uCEA/uCAS cohort (2.6%). The uCEA/uCAS cohort compared with other cohorts had the lowest presenting stroke severity (NIHSS 4.9 vs NIHSS 6.9-16.0), and best neurologic outcomes (mRS 1.7 vs mRS 1.8-2.6). CONCLUSIONS: After an ischemic stroke, patients undergoing urgent carotid interventions had the lowest presenting stroke severity (NIHSS) and highest rate of independent neurologic outcomes (mRS) compared with other stroke interventions. Incoming stroke severity correlates with functional neurologic outcomes, and patients who present with an NIHSS of 10 or less who undergo uCEA/uCAS have a high likelihood of independent neurologic functional outcome (mRS of ≤2).

Climate change is threatening the health of current and future generations of children. The most recent evidence from the Lancet Countdown: Tracking Progress on Health and Climate Change finds declining trends in yield potential of major crops, rising heatwave exposures, and increasing climate suitability for the transmission of infectious diseases, putting at risk the health and wellbeing of children around the world. However, if children are considered at the core of planning and implementation, the policy responses to climate change could yield enormous benefits for the health and wellbeing of children throughout their lives. Child health professionals have a role to play in ensuring this, with the beneficiaries of their involvement ranging from the individual child to the global community. The newly established Children in All Policies 2030 initiative will work with the Lancet Countdown to provide the evidence on the climate change responses necessary to protect and promote the health of children.

BACKGROUND: Delirium after acute stroke is a serious complication. Numerous studies support a benefit of multicomponent interventions in minimizing delirium-related complications in at-risk patients, but this has not been reported in acute stroke patients. The purpose of this study was to explore the feasibility of conducting a randomized (delirium care) versus usual standardized stroke care (usual care) in reducing delirium in acute stroke. OBJECTIVE: This pilot study assessed the feasibility of (1) enrollment within the 48-hour window when delirium risk is greatest, (2) measuring cognitive function using the Montreal Cognitive Assessment, (3) delivering interventions 7 days per week, and (4) determining delirium incidence in stroke-related cognitive dysfunction. METHODS: A 2-group randomized controlled trial was conducted. Patients admitted with ischemic and hemorrhagic strokes and 50 years or older, English speaking, and without delirium on admit were recruited, consented, and randomized to usual care or delirium care groups. RESULTS: Data from 125 subjects (delirium care, n = 59; usual care, n = 66) were analyzed. All Montreal Cognitive Assessment subscales were completed by 86% of subjects (delirium care, mean [SD], 18.14 [6.03]; usual care, mean [SD], 17.61 [6.29]). Subjects in the delirium care group received a mean of 6.10 therapeutic activities (range, 2-23) and daily medication review by a clinical pharmacist using anticholinergic drug calculations. Delirium incidence was 8% (10/125), 3 in the delirium care group and 7 in the usual care group. CONCLUSION: Findings support the feasibility of delivering a multicomponent delirium prevention intervention in acute stroke and warrants testing intervention effects on delirium outcomes and anticholinergic medication administration.

United States (US) and worldwide telestroke programs frequently focus only on emergency room hyper-acute stroke management. This article describes a comprehensive, telemedicine-enabled, stroke care delivery system that combines "drip and ship" and "drip and keep" models with a comprehensive stroke center primary hub at Ochsner Medical Center in New Orleans, advanced stroke-capable regional hubs, and geographically-aligned, "stroke-ready" spokes. The primary hub provides vascular neurology expertise via telemedicine and monitors care for patients remaining at regional hubs and spokes using a multidisciplinary team approach. By 2014, primary hub telestroke consults grew to ≈1000/year with 16 min average door to consult initiation and 20 min to completion, and 29% of ischemic stroke patients received recombinant tissue-type plasminogen activator (rtPA), increasing 275%. Most patients remained in hospitals close to home, but neurointensive care and interventional procedures were common reasons for primary hub transfer. Given the time sensitivity and expert consultation needed for complex acute stroke care delivery paradigms, telestroke programs are effective for fulfilling unmet care needs. Combining drip and ship and drip and keep management allows more patients to stay "local," limiting primary hub transfer unless more advanced services are required. Post admission telestroke management at spokes increases personnel efficiency and can positively impact stroke outcomes.

OBJECTIVE: Carotid intervention shortly after an acute neurologic ischemic event is being performed more frequently in stroke centers to reduce the risk of recurrent stroke. Thrombolysis with recombinant tissue plasminogen activator (tPA) is offered to select patients with ischemic stroke symptoms who present within 4.5 hours. However, there is a paucity of data as to whether tPA followed by urgent carotid endarterectomy (CEA) or carotid artery stenting (CAS) has an increased risk of complications, particularly intracerebral hemorrhage (ICH). We sought to determine the periprocedural complications of urgently performed CEA or CAS following tPA. METHODS: From January 2009 to January 2015, 762 patients underwent carotid interventions (CEA, n = 440; CAS, n = 322) at a tertiary referral center and 165 patients (21.6%) underwent an urgent CEA or CAS during the index hospitalization for an acute transient ischemic attack or stroke. We compared the effect of intravenous tPA on 30-day complications, including ICH. The χ(2) and Fisher exact tests were used to determine significance between groups. RESULTS: During the 6-year period, 165 patients underwent urgent carotid interventions (CEA, n = 135; CAS, n = 30) for acute neurologic symptoms. Of these, 19% (31 patients [CEA, n = 25; CAS, n = 6]) had tPA for an acute stroke; the remaining (134 patients [CEA, n = 110; CAS, n = 24]) fell outside of the tPA time window. Most strokes were minor or moderate with a mean National Institutes of Health Stroke Scale (NIHSS) score of 6.6 (range, 0-19). The mean time to intervention for both groups was 2.4 days (0-15 days). The 30-day stroke, death, and myocardial infarction rates were 9.7% (3 of 31) for the tPA group compared with 4.5% (6 of 134) for the no-tPA group (P = .37). Including bleeding complications in these 30-day outcomes, there was no difference between the tPA (3 of 31) and the no-tPA cohorts (8 of 134; P = .43). In the tPA group, there were one ICH, one neck hematoma/death, and an additional death; in the no-tPA group, there were one ICH, two neck hematomas, one stroke, two myocardial infarctions, one ICH/death, and one additional death. No significant increased rates of bleeding were noted within the tPA group (2 of 31) compared with the no-tPA group (4 of 134; P = .32). Moreover, in the tPA cohort, more than half of the patients (17 of 31) underwent revascularization within 72 hours (CEA = 13; CAS = 4) with outcomes similar to those who underwent revascularization after 72 hours. CONCLUSIONS: Thrombolysis followed by urgent CEA or CAS is not associated with an increased risk of complications in select patients who present with acute neurologic symptoms. Selection of patients is important; there was no ICH and only one death in each group for patients with minor to moderate ischemic stroke (NIHSS score <10).
