Neuroendovascular Rescue 2025: Trends in Stroke Endovascular Therapy.

Neuroendovascular rescue of patients with acute ischemic stroke caused by a large arterial occlusion has evolved throughout the first quarter of the present century, and continues to do so. Starting with the intra-arterial instillation of thrombolytic agents via microcatheters to dissolve occluding thromboembolic material, the current status is one that includes a variety of different techniques such as direct aspiration of thrombus, removal by stent retriever, adjuvant techniques such as balloon angioplasty, stenting, and tactical intra-arterial instillation of thrombolytic agents in smaller branches to treat no-reflow phenomenon. The results have been consistently shown to benefit these patients, irrespective of whether they had already received intravenous tissue-type plasminogen activator or not. Improved imaging methods of patient selection and tactically optimized periprocedural care measures complement this dimension of the practice of neurointervention.

Immunotherapy and stereotactic body radiotherapy for older patients with non-metastatic renal cancer unfit for surgery or decline nephrectomy: practical proposal by the International Geriatric Radiotherapy Group.

The standard of care for non-metastatic renal cancer is surgical resection followed by adjuvant therapy for those at high risk for recurrences. However, for older patients, surgery may not be an option due to the high risk of complications which may result in death. In the past renal cancer was considered to be radio-resistant, and required a higher dose of radiation leading to excessive complications secondary to damage of the normal organs surrounding the cancer. Advances in radiotherapy technique such as stereotactic body radiotherapy (SBRT) has led to the delivery of a tumoricidal dose of radiation with minimal damage to the normal tissue. Excellent local control and survival have been reported for selective patients with small tumors following SBRT. However, for patients with poor prognostic factors such as large tumor size and aggressive histology, there was a higher rate of loco-regional recurrences and distant metastases. Those tumors frequently carry program death ligand 1 (PD-L1) which makes them an ideal target for immunotherapy with check point inhibitors (CPI). Given the synergy between radiotherapy and immunotherapy, we propose an algorithm combining CPI and SBRT for older patients with non-metastatic renal cancer who are not candidates for surgical resection or decline nephrectomy.

The Impact of Radiation Therapy in Patients with Systemic Sclerosis and Head and Neck Cancer.

OBJECTIVE: Systemic sclerosis (SSc) is considered a relative, or in some cases, absolute contraindication for radiation therapy for various cancers; however, radiation is the standard of care and the best option for tumor control for locally advanced head and neck (H&N) cancer. We present a case series to document postradiation outcomes in patients with SSc and H&N cancer. METHODS: Patients with SSc and H&N cancer treated with radiation were identified from the Johns Hopkins Scleroderma Center and the University of Pittsburgh Scleroderma Center research registries. Through chart review, we identified whether patients developed predetermined acute and late side effects or changes in SSc activity from radiation. We further describe therapies used to prevent and treat radiation-induced fibrosis. RESULTS: Thirteen patients with SSc who received radiation therapy for H&N cancer were included. Five-year survival was 54%. Nine patients (69%) developed local radiation-induced skin thickening, and 7 (54%) developed reduced neck range of motion. Two patients required long-term percutaneous endoscopic gastrostomy use due to radiation therapy complications. No patients required respiratory support related to radiation therapy. Regarding SSc disease activity among the patients with established SSc before radiation therapy, none experienced interstitial lung disease progression in the postradiation period. After radiation, one patient had worsening skin disease outside the radiation field; however, this patient was within the first year of SSc, when progressive skin disease is expected. Treatment strategies to prevent radiation fibrosis included pentoxifylline, amifostine, and vitamin E, while intravenous immunoglobulin (IVIG) was used to treat it. CONCLUSION: Although some patients with SSc who received radiation for H&N cancer developed localized skin thickening and reduced neck range of motion, systemic flares of SSc were uncommon. This observational study provides evidence to support the use of radiation therapy for H&N cancer in patients with SSc when radiation is the best treatment option.

Immunotherapy and radiotherapy for older patients with locally advanced rectal cancer unfit for surgery or decline surgery: a practical proposal by the International Geriatric Radiotherapy Group.

The standard of care for locally advanced rectal cancer is total neoadjuvant therapy followed by surgical resection. Current evidence suggests that selected patients may be able to delay or avoid surgery without affecting survival rates if they achieve a complete clinical response (CCR). However, for older cancer patients who are too frail for surgery or decline the surgical procedure, local recurrence may lead to a deterioration of patient quality of life. Thus, for clinicians, a treatment algorithm which is well tolerated and may improve CCR in older and frail patients with rectal cancer may improve the potential for prolonged remission and potential cure. Recently, immunotherapy with check point inhibitors (CPI) is a promising treatment in selected patients with high expression of program death ligands receptor 1 (PD- L1). Radiotherapy may enhance PD-L1 expression in rectal cancer and may improve response rate to immunotherapy. We propose an algorithm combining immunotherapy and radiotherapy for older patients with locally advanced rectal cancer who are too frail for surgery or who decline surgery.

Optimizing workflow of urgent stroke endovascular intervention: A focused lean six sigma project.

INTRODUCTION: Urgent endovascular intervention is currently accepted as the primary and critical therapeutic approach to patients whose acute ischemic stroke results from a large arterial occlusion (LAO). In this context, one of the quality metrics most widely applied to the assessment of emergency systems performance is the "door-to-puncture" (D-P) time. We undertook a project to identify the subinterval of the D-P metric causing the most impact on workflow delays and created a narrowly focused project on improving such subinterval. METHODS: Using the DMAIC (i.e., define, measure, analyze, improve and control) approach, we retrospectively reviewed our quality stroke data for calendar year (CY) 2021 (i.e., baseline population), completed a statistical process control assessment, defined the various subintervals of the D-P interval, and completed a Pareto analysis of their duration and their proportional contribution to the D-P interval. We retooled our workflow based on these analyses and analyzed the data resulting from its implementation between May and December 2022 (i.e., outcome population). RESULTS: The baseline population included 87 patients (44 men; mean age = 67.2 years). Their D-P process was uncontrolled, and times varied between 35-235 minutes (Mean = 97; SD = 38.40). Their door to angiography arrival (D-AA) subinterval was significantly slower than their arrival to puncture (AA-P) (73.4 v. 23.5 minutes; p < 0.01), accounted for 73% of the average length of the D-P interval. The group page activation to angiography arrival (GP-AA) subinterval accounted for 41.5% of the entire D-AA duration, making it the target of our project. The outcome population originally consisted of 38 patients (15 men; mean age = 70.3 years). Their D-P process was controlled, its times varying between 43-177 minutes (Mean = 85.8; SD = 34.46), but not significantly difference than the baseline population (p = 0.127). Their target subinterval GP-AA varied between 0-37 minutes and was significantly improved from the baseline population (Mean = 13.21 v. 29.68; p < 0.001). CONCLUSIONS: It seems feasible and reasonable to analyze the subinterval components of complex quality metrics such as the D-P time and carry out more focused quality improvement projects. Care must be exercised when interpreting the impact on overall system performance, due to unexpected variations within interdependent subprocesses. The application of a robust and comprehensive LSS continuous quality improvement process in any CSC will have to include individualized focused projects that simultaneously control the different components of overall system performance.

Spreading Depolarizations Contribute to the Acute Behavior Deficits Associated With a Mild Traumatic Brain Injury in Mice.

Concussions or mild traumatic brain injuries (mTBIs) are often described and diagnosed by the acute signs and symptoms of neurological dysfunction including weakness, dizziness, disorientation, headaches, and altered mental state. The cellular and physiological mechanisms of neurological dysfunction and acute symptoms are unclear. Spreading depolarizations (SDs) occur after severe TBIs and have recently been identified in closed-skull mouse models of mTBIs. SDs are massive waves of complete depolarization that result in suppression of cortical activity for multiple minutes. Despite the clear disruption of brain physiology after SDs, the role of SDs in the acute neurological dysfunction and acute behavioral deficits following mTBIs remains unclear. We used a closed-skull mouse model of mTBI and a series of behavioral tasks collectively scored as the neurological severity score (NSS) to assess acute behavior. Our results indicate that mTBIs are associated with significant behavioral deficits in the open field and NSS tasks relative to sham-condition animals. The behavioral deficits associated with the mTBI recovered within 3 h. We show here that the presence of mTBI-induced bilateral SDs were significantly associated with the acute behavioral deficits. To identify the role of SDs in the acute behavioral deficits, we used exogenous potassium and optogenetic approaches to induce SDs in the absence of the mTBI. Bilateral SDs alone were associated with similar behavioral deficits in the open field and NSS tasks. Collectively, these studies demonstrate that bilateral SDs are linked to the acute behavioral deficits associated with mTBIs.

Study Protocol for the Breathe Easier Trial: A Pilot RCT of a Dyad-Based, Multiple-Behavior Intervention for Improving Physical and Emotional Health in Survivors Facing Lung Cancer.

BACKGROUND: Research targeting survivors of lung cancer has yet to adequately address the management of physical deconditioning and unresolved symptoms (dyspnea, fatigue). The objective of the Breathe Easier trial is to test the feasibility and preliminary effects of a theory-based, multiple-behavior intervention (physical activity, smoking reduction for current smokers, stress management) targeting survivors of localized non-small-cell lung cancer (NSCLC, stages I-III) and their supportive partners. METHODS: This pilot RCT will enroll 30 dyads (60 participants). Each dyad will consist of one survivor and one partner (defined as a family member or friend) Dyads will be randomized to the Intervention Group (IG) or the Attention Control Group (AC). IG members will receive the 12-week, home-based intervention based on the individual and family self-management theory, which targets improvements in self-efficacy, social support, and self-regulation. Improvement in lifestyle behaviors is a proximal outcome. Improvements in physical and emotional health are distal outcomes. Breathe Easier (IG) includes educational content written in plain language as well as breathing exercises and meditations; SMART goal setting; daily text messaging; and weekly telephone calls with trained staff. The AC program includes relevant National Institutes of Health publications plus weekly telephone chats. Members who currently smoke will also receive an evidence-based smoking cessation resource. DISCUSSION: Breathe Easier focuses on changes in multiple behaviors in dyads coping with a diagnosis of NSCLC (stages I-III) with the overall purpose of improving physical and emotional health. Findings will provide additional evidence of the feasibility and preliminary effects of this intervention. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT05956782; This trial was registered retrospectively.

Immunotherapy and Hypofractionated Radiotherapy in Older Patients with Locally Advanced Cutaneous Squamous-Cell Carcinoma of the Head and Neck: A Proposed Paradigm by the International Geriatric Radiotherapy Group.

Cutaneous skin carcinoma is a disease of older patients. The prevalence of cutaneous squamous-cell carcinoma (cSCC) increases with age. The head and neck region is a frequent place of occurrence due to exposure to ultraviolet light. Surgical resection with adjuvant radiotherapy is frequently advocated for locally advanced disease to decrease the risk of loco-regional recurrence. However, older cancer patients may not be candidates for surgery due to frailty and/or increased risk of complications. Radiotherapy is usually advocated for unresectable patients. Compared to basal-cell carcinoma, locally advanced cSCC tends to recur locally and/or can metastasize, especially in patients with high-risk features such as poorly differentiated histology and perineural invasion. Thus, a new algorithm needs to be developed for older patients with locally advanced head and neck cutaneous squamous-cell carcinoma to improve their survival and conserve their quality of life. Recently, immunotherapy with checkpoint inhibitors (CPIs) has attracted much attention due to the high prevalence of program death ligand 1 (PD-L1) in cSCC. A high response rate was observed following CPI administration with acceptable toxicity. Those with residual disease may be treated with hypofractionated radiotherapy to minimize the risk of recurrence, as radiotherapy may enhance the effect of immunotherapy. We propose a protocol combining CPIs and hypofractionated radiotherapy for older patients with locally advanced cutaneous head and neck cancer who are not candidates for surgery. Prospective studies should be performed to verify this hypothesis.

Risk of new cerebral ischemic events in patients with symptomatic internal carotid artery stenosis while awaiting carotid stent placement.

BACKGROUND AND PURPOSE: Although there is an emphasis on performing carotid artery stent (CAS) placement within 2 weeks after index event of transient ischemic attack (TIA) or minor stroke in patients with significant extracranial internal carotid artery (ICA) stenosis, the risks and characteristics of recurrent cerebral ischemic event while waiting for CAS placement are not well defined. METHOD: We analyzed patients admitted to our institution over a 45-month period with symptomatic extracranial ICA stenosis. We identified any new cerebral ischemic events that occurred between index cerebral or retinal ischemic event and CAS placement and categorized them as TIA and minor or major ischemic strokes. We calculated the risk of new ipsilateral cerebral ischemic events between index cerebral or retinal ischemic event and CAS placement. RESULTS: The mean age of 131 patients analyzed was 67 years (range: 47-94 years; 92 were men), and 94 and 37 patients had 70%-99% and 50%-69% severity of stenosis, respectively. The mean and median time intervals between index cerebral or retinal ischemic event and CAS performance were 28 (standard deviation [SD] 30) and 7 (interquartile range 33) days, respectively. A total of 9 of 131 patients (6.9%, 95% confidence interval 2.5%-11.2%) experienced new cerebral ischemic events over 3637 patient days of observation. The risk of new ipsilateral cerebral ischemic events was 2.5 per 1000 patient days of observation. CONCLUSION: We estimated the risk of new ipsilateral cerebral ischemic events in patients with ICA stenosis ≥50% in severity while waiting for CAS placement to guide appropriate timing of procedure.

Effect of race/ethnicity on arterial recanalization following intravenous thrombolysis in acute ischemic stroke patients.

INTRODUCTION: Several reports have identified that clinical outcomes such as death or disability in acute ischemic stroke (AIS) patients following intravenous (IV) tissue plasminogen activator (tPA) treatment can vary according to race and ethnicities. We determined the effect of race/ethnicity on rates of arterial recanalization in AIS patients with large vessel occlusion (LVO) after IV tPA. METHODS: We analyzed 234 patients with LVO detected on computed tomographic angiography (CTA) who received IV tPA and subsequently underwent angiography for potential thrombectomy. The primary occlusion sites on CTA and digital subtracted angiography (DSA) were compared and a score was given to the level of recanalization with values ranging from 1 (complete recanalization), 2 (partial recanalization), or 3 (no recanalization).The effect of race/ethnicity were assessed for predicting vessel recanalization using the covariates of age, gender, time since stroke onset, tPA dose received, NIHSS (National Institute of Health Stroke Scale) score at baseline, and location of the occlusion, using logistic regression analysis. RESULTS: Five patients (2.1%) were Hispanic or Latino, 8 (3.4%) Asian, 24 (10.3%) African American, and 197 (84.2%) White. A total of 50% had a distal ICA/proximal M1 occlusion, 20% distal M1 occlusion, and 16% single M2 occlusion. At the primary occlusion site, 44 (18.8%) had complete recanalization on post IV tPA angiogram, 17 (7.3%) had partial recanalization, and 165 (70.5%) had no recanalization. We did not find any association between race/ethnicity and vessel recanalization post IV tPA (Nonwhite combined [OR=1.49, p=0.351]; Asian [OR=1.460, p=0.650]; African American [OR=1.508, p=0.415]; White [OR=0.672, p=0.351]; ethnicity (Hispanic or Latino) [OR= 1.008, p=0.374]); Occlusion location (OR=0.189, p<0.001). Final TICI scores and mRS at 90 days were similar among the different groups. CONCLUSION: Approximately 19% of patients had complete recanalization after IV tPA, but race and ethnicity did not seem to have an effect on arterial recanalization. Arterial recanalization was only affected by location of occlusion.

Recognition and Management of the Long-term Effects of Cranial Radiation.

OPINION STATEMENT: Cranial radiation is ubiquitous in the treatment of primary malignant and benign brain tumors as well as brain metastases. Improvement in radiotherapy targeting and delivery has led to prolongation of survival outcomes. As long-term survivorship improves, we also focus on prevention of permanent side effects of radiation and mitigating the impact when they do occur. Such chronic treatment-related morbidity is a major concern with significant negative impact on patient's and caregiver's respective quality of life. The actual mechanisms responsible for radiation-induced brain injury remain incompletely understood. Multiple interventions have been introduced to potentially prevent, minimize, or reverse the cognitive deterioration. Hippocampal-sparing intensity modulated radiotherapy and memantine represent effective interventions to avoid damage to regions of adult neurogenesis. Radiation necrosis frequently develops in the high radiation dose region encompassing the tumor and surrounding normal tissue. The radiographic findings in addition to the clinical course of the patients' symptoms are taken into consideration to differentiate between tissue necrosis and tumor recurrence. Radiation-induced neuroendocrine dysfunction becomes more pronounced when the hypothalamo-pituitary (HP) axis is included in the radiation treatment field. Baseline and post-treatment evaluation of hormonal profile is warranted. Radiation-induced injury of the cataract and optic system can develop when these structures receive an amount of radiation that exceeds their tolerance. Special attention should always be paid to avoid irradiation of these sensitive structures, if possible, or minimize their dose to the lowest limit.

Impact of COVID-19 pandemic on older cancer patients: Proposed solution by the International Geriatric Radiotherapy Group.

Older cancer patients are disproportionally affected by the Coronavirus 19 (COVID-19) pandemic. A higher rate of death among the elderly and the potential for long-term disability have led to fear of contracting the virus in these patients. This fear can, paradoxically, cause delay in diagnosis and treatment that may lead to a poor outcome that could have been prevented. Thus, physicians should devise a policy that both supports the needs of older patients during cancer treatment, and serves to help them overcome their fear so they seek out to cancer diagnosis and treatment early. A combination of telemedicine and a holistic approach, involving prayers for older cancer patients with a high level of spirituality, may improve vaccination rates as well as quality of life during treatment. Collaboration between health care workers, social workers, faith-based leaders, and cancer survivors may be crucial to achieve this goal. Social media may be an important component, providing a means of sending the positive message to older cancer patients that chronological age is not an impediment to treatment.

Hyperglycemic control in acute ischemic stroke patients undergoing endovascular treatment: post hoc analysis of the Stroke Hyperglycemia Insulin Network Effort trial.

BACKGROUND: Hyperglycemia has been associated with poor outcomes in acute ischemic stroke patients undergoing endovascular treatment. We analyzed the effect of intensive glucose control on death and disability rates in patients with acute ischemic stroke undergoing endovascular treatment. METHODS: We analyzed the effect of intensive (serum glucose <110 mg/dL) glucose treatment (compared with standard treatment, serum glucose <180 mg/dL) in patients who received endovascular treatment in the Stroke Hyperglycemia Insulin Network Effort (SHINE) trial. We further analyzed the effect of area under the curve (AUC) of serum glucose, proportion of the time blood glucose was <140 mg/dL, and glucose variability defined as the glucose range during 72 hours. The primary outcomes were neurological deterioration within 72 hours and outcome at 90 days. RESULTS: A total of 146 patients (mean age 68.1±13.9 years, 50.7% men) underwent endovascular treatment for acute ischemic stroke; 72 and 74 patients were randomized to intensive and standard treatments, respectively. The rates of death (20.3% and 22.2%), favorable 90-day primary outcome (17.6% and 19.4%), and serious adverse events (41.9% and 56.98%) were similar between the two groups. The AUC of serum glucose was not associated with death within 90 days (OR 1, 95% CI 1 to 1) or favorable outcome at 90 days (OR 1, 95% CI 1 to 1). Glucose variability was not associated with death or favorable outcome at 90 days. CONCLUSION: We did not identify any beneficial effect of intensive glucose reduction on rates of death or favorable outcomes at 90 days among acute ischemic stroke patients undergoing endovascular treatment.

Endovascular Thrombectomy With or Without Intravenous Thrombolysis: A Meta-Analysis of Randomized Controlled Trials.

BACKGROUND: We performed this meta-analysis of randomized clinical trials to compare the outcomes in patients treated with endovascular thrombectomy who receive prior intravenous thrombolysis with those who do not receive such treatment. Recently, one randomized trial reported outcomes to address this issue, so timely update of meta-analysis is needed to determine the value of administering intravenous thrombolysis before endovascular thrombectomy. MATERIALS AND METHODS: Four randomized clinical trials are included in our meta-analysis. We calculated pooled odds ratios and 95% CIs using random-effects models. The primary efficacy endpoint was a favorable outcome defined by a modified Rankin Scale score of 0 (no symptoms), 1 (no significant disability), or 2 (slight disability) at 90 days post-randomization. Secondary endpoints analyzed were any intracerebral hemorrhage, symptomatic intracerebral hemorrhage, and mortality. RESULTS: Of the 1633 patients randomized, the proportion of patients who achieved a favorable outcome was similar between endovascular thrombectomy alone and combined approach with intravenous thrombolysis and endovascular thrombectomy (1631 patients analyzed; odds ratio 1.02; CI 0.84-1.25; p = 0.83). Risk of any intracerebral hemorrhage was significantly lower among those randomized to endovascular thrombectomy alone (1633 patients analyzed; odds ratio 0.75; CI 0.57-0.99; p = 0.04). Rates of symptomatic intracerebral hemorrhage (p = 0.36) and mortality (p = 0.62) were not significantly different between the two groups. CONCLUSIONS: Compared with endovascular thrombectomy preceded by intravenous thrombolysis, endovascular thrombectomy resulted in similar rates of favorable outcome with a lower rate of intracerebral hemorrhage. A large phase 3 trial is required to conclusively demonstrate equivalency of both approaches to guide future practice.

New cardiovascular events in the convalescent period among survivors of SARS-CoV-2 infection.

BACKGROUND: Patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection may have an increased risk of acute cardiovascular events in the convalescent period. AIMS: To determine whether patients with SARS-CoV-2 infection have an increased risk of cardiovascular events during the convalescent period. METHODS: We analyzed 10,691 hospitalized adult pneumonia patients with SARS-CoV-2 infection and contemporary matched controls of pneumonia patients without SARS-CoV-2 infection. The risk of new cardiovascular events following >30 days pneumonia admission (convalescent period) was ascertained using Cox proportional hazards regression analysis to adjust for potential confounders. RESULTS: Among 10,691 pneumonia patients with SARS-CoV-2 infection, 697 patients (5.8%; 95% CI, 5.4-6.2%) developed new cardiovascular events (median time interval of 218 days post pneumonia admission; interquartile range Q1 = 117 days, Q3 = 313 days). The risk of new cardiovascular events was not significantly higher among pneumonia patients with SARS-CoV-2 infection compared with those with pneumonia without SARS-CoV-2 infection (hazard ratio (HR), 0.90, 95% CI, 0.80-1.02) after adjustment for potential confounders. In addition, no significant difference in the rate of a new ischemic stroke (HR, 0.84; 95% CI, 0.70-1.02) or ischemic heart disease (HR, 1.00; 95% CI, 0.87-1.15) was observed between the pneumonia patients with and without SARS-CoV-2 infection. CONCLUSION: Our study suggests that new cardiovascular events rate in the convalescent period among pneumonia patients with SARS-CoV-2 infection was not significantly higher than the rate seen with other pneumonias.

Radiation-induced optic neuropathy: a review.

Radiation is a commonly used treatment modality for head and neck as well as CNS tumours, both benign and malignant. As newer oncology treatments such as immunotherapies allow for longer survival, complications from radiation therapy are becoming more common. Radiation-induced optic neuropathy is a feared complication due to rapid onset and potential for severe and bilateral vision loss. Careful monitoring of high-risk patients and early recognition are crucial for initiating treatment to prevent severe vision loss due to a narrow therapeutic window. This review discusses presentation, aetiology, recent advances in diagnosis using innovative MRI techniques and best practice treatment options based on the most recent evidence-based medicine.

Universal admission laboratory screening for severe acute respiratory coronavirus virus 2 (SARS-CoV-2) asymptomatic infection across a large health system.

BACKGROUND: Admission laboratory screening for asymptomatic coronavirus disease 2019 (COVID-19) has been utilized to mitigate healthcare-associated severe acute respiratory coronavirus virus 2 (SARS-CoV-2) transmission. An understanding of the impact of such testing across a variety of patient populations is needed. METHODS: SARS-CoV-2 nucleic acid amplification admission testing results for all asymptomatic patients across 4 distinct inpatient facilities between April 20, 2020, and June 14, 2021, were analyzed. Positivity rates and the number needed to test (NNT) to identify 1 asymptomatic infected patient were calculated. Admission results were compared to COVID-19 community incidence rates for the system's surrounding metropolitan service area. Using a national survey of hospital epidemiologists, a clinically meaningful NNT of 1:100 was identified. RESULTS: In total, 51,187 tests were collected (positivity rate, 1.8%). During periods of high transmission, the NNT met the clinically relevant threshold in all populations. The NNT approached or met the threshold for most locations during periods of lower transmission. For all transmission levels, the NNT for fully vaccinated patients did not meet the threshold. CONCLUSIONS: Implementing an asymptomatic patient admission testing program can provide clinically relevant data based on the NNT, even during periods of lower transmission and among different patient populations. Limiting admission testing to non-fully vaccinated patients during periods of lower transmission may be a strategy to address resource concerns around this practice. Although the impact of such testing on healthcare-associated COVID-19 among patients and healthcare workers could not be clearly determined, these data provide important information as facilities weigh the costs and benefits of such testing.

Outcomes with IV tenecteplase and IV alteplase for acute ischemic stroke with or without thrombectomy in real-world settings in the United States.

BACKGROUND AND PURPOSE: Although many stroke centers in United States are using intravenous (IV) tenecteplase (TNK) for acute ischemic stroke patients, there is paucity of comparative data between IV TNK and IV alteplase from real-world settings. MATERIALS AND METHODS: We analyzed the data from 122 healthcare facilities in Cerner Real World Data and included patients admitted between February 2016 to April 2022 to determine the effect of IV TNK (compared with IV alteplase) on occurrence of two outcomes in acute ischemic stroke patients stratified by use of thrombectomy: non-routine discharge or death, and intracranial hemorrhage after adjusting for potential confounders. RESULTS: Among 30,643 acute ischemic stroke patients analyzed, 29,480 (96.2%) and 1,163 (3.8%) patients received IV alteplase and IV TNK, respectively. The proportion of patients who received thrombectomy was significantly higher among patients who received IV TNK compared with those who received IV alteplase (16.7% versus 11.0%, p<0.001). Occurrence of intracranial hemorrhage was more common among patients treated with IV TNK in acute ischemic stroke patients who did not receive thrombectomy (7.9% versus 5.1%, p<0.001) but not in those who received thrombectomy (20.1% versus 16.8%, p = 0.234). In the logistic regression analysis, patients treated with IV TNK who did not receive thrombectomy were at higher risk of intracranial hemorrhage (OR, 1.34, 95% CI 1.05-1.72, p = 0.02) after adjusting for age (age strata), gender, race/ethnicity, hypertension, diabetes mellitus, atrial fibrillation, hyperlipidemia, malignancy, nicotine dependence, previous ischemic stroke, previous transient ischemic attack, previous intracerebral hemorrhage, previous subarachnoid hemorrhage, previous acute myocardial infarction, atherosclerosis of aorta, previous AKI, congestive heart failure, peripheral vascular disease, and hospital type, aphasia, hemiplegia, neglect, somnolence, stupor and coma, dysphagia, and homonymous hemianopsia. There was no difference in the rate of non-routine discharge or death between patients treated with IV TNK and those treated with IV alteplase in the multivariate analyses. CONCLUSIONS: In an analysis of real-world data, IV TNK was associated with higher rates of intracranial hemorrhage compared with IV alteplase in patients with acute ischemic stroke who did not undergo thrombectomy.

Development and testing of "Is Lung Cancer Screening for You?" A computer-based decision aid.

PURPOSE: To reduce lung cancer mortality, individuals at high-risk should receive a low-dose computed tomography screening annually. To increase the likelihood of screening, interventions that promote shared decision-making are needed. The goal of this study was to investigate the feasibility, acceptability, usability, and preliminary effectiveness of a computer-based decision aid. METHODS: Thirty-three participants were recruited through primary-care clinics in a small southeastern-US city. Participants used a computer-based decision aid ("Is Lung Cancer Screening for You?") during a clinic appointment. Paper surveys collected self-reported feasibility, acceptability, and usability data. A research coordinator was present to observe each patient's and health-care provider's interactions, and to assess the fidelity of shared decision-making. RESULTS: The decision aid was feasible, acceptable for use in a clinic setting, and easy for participants to use. Patients had low decisional conflict following use of the decision aid and had high screening intention and actual screening rates. Shared decision-making discussions using the decision aid were nearly 6 min on average. CONCLUSION: Computer-based decision aids are feasible for promoting shared lung cancer-screening decisions. A more robust study is warranted to measure the added value of a computer-based version of this aid versus a paper-based aid.
