Background: Although it is well-known that intracerebral hemorrhage (ICH) is associated with physical and psychological morbidity, there is scant data on factors influencing social engagement after ICH. Understanding the relationship between functionality, psychological outcome and social engagement post-bleed may facilitate identification of patients at high risk for social isolation after ICH. Methods: Patients ≥18-years-old with non-traumatic ICH from January 2015-March 2023 were identified from the Neurological Emergencies Outcomes at NYU (NEON) registry. Data on discharge functionality were collected from the medical record. 3-months post-bleed, patients/their legally-authorized representatives (LARs) were contacted to complete Neuro-QoL social engagement, anxiety, depression, and sleep inventories. Patients were stratified by ability to participate in social roles and activities (good=T-score>50, poor=T-score≤50) and satisfaction with social roles and activities (high=T-score>50 and low=T-score≤50). Univariate comparisons were performed to evaluate the relationship between post-bleed social engagement and both functionality and psychological outcome using Pearson's chi-square, Fisher's Exact test, and Mann-Whitney U tests. Multivariate logistic regression was subsequently performed using variables that were significant on univariate analysis (p<0.05). Results: The social engagement inventories were completed for 55 patients with ICH; 29 (53 %) by the patient alone, 14 (25 %) by a LAR alone, and 12 (22 %) by both patient and LAR. 15 patients (27 %) had good ability to participate in social roles and activities and 10 patients (18 %) had high satisfaction with social roles and activities. Social engagement was associated with both functionality and psychological outcome on univariate analysis, but on multivariate analysis, it was only related to functionality; post-bleed ability to participate in social roles and activities was associated with discharge home, discharge GCS score, discharge mRS score, and discharge NIHSS score (p<0.05) and post-bleed satisfaction with social roles and activities was related to discharge mRS score and discharge NIHSS score (p<0.05). Conclusion: In patients with nontraumatic ICH, social engagement post-bleed was related to discharge functionality, even when controlling for depression, anxiety, and sleep disturbance.

INTRODUCTION AND PROBLEM STATEMENT/UNASSIGNED:A chief resident's role incorporates administrative, academic, and interpersonal responsibilities essential to managing a successful residency program. However, rising chief residents receive little formal exposure to leadership training. OBJECTIVES/UNASSIGNED:To (1) define leadership styles; (2) understand the effect of cultural competence on leadership styles; (3) learn effective methods to advocate as the chief resident; (4) provide effective peer feedback; (5) provide effective supervisor feedback; (6) learn effective conflict management; (7) ensure psychological safety. METHODS AND CURRICULUM DESCRIPTION/UNASSIGNED:We developed a 1-day curriculum combining didactics and simulation activities for our program's rising chief residents. Implementation of our curricular design included a morning session focusing on small groups and didactic-based lectures on specific topics pertinent to leadership, along with a debriefing of a psychometric evaluation tool administered before the curriculum day. The simulation activity consisted of 3 group objective structured clinical examination (G-OSCE) scenarios: (1) providing a struggling junior trainee with feedback; (2) debriefing an adverse clinical outcome as the team leader; (3) navigating a challenging situation with a supervising physician. Standardized participants were surveyed for specific objectives. Learners completed precurricular and postcurricular surveys on their familiarity and preparedness for their chief year. RESULTS AND ASSESSMENT DATA/UNASSIGNED:= 0.421), learner-reported use of wellness resources was noted to be reduced after the curricular intervention and remains a result of further interest for exploration. DISCUSSION AND LESSONS LEARNED/UNASSIGNED:A 1-day leadership development curriculum combining didactics and simulation is an effective means of preparing rising chief residents to succeed in their transition to this leadership role.

OBJECTIVES/OBJECTIVE:The objective of this study was to determine factors associated with negative disease-related stigma after hemorrhagic stroke. MATERIALS AND METHODS/METHODS:Patients with non-traumatic hemorrhage (ICH or SAH) admitted between January 2015 and February 2021 were assessed by telephone 3-months after discharge using the Quality of Life in Neurological Disorders (Neuro-QoL) Negative Disease-Related Stigma Short Form inventory. We evaluated the relationship between disease-related stigma (T-score >50) and pre-stroke demographics, admission data, and poor functional outcome (3-month mRS score 3-5 and Barthel Index <100). RESULTS:We included 89 patients (56 ICH and 33 SAH). The median age was 63 (IQR 50-69), 43 % were female, and 67 % graduated college. Admission median GCS score was 15 (IQR 13-15) and APACHE II score was 12 (IQR 9-17). 31 % had disease-related stigma. On univariate analysis, disease-related stigma was associated with female sex, non-completion of college, GCS score, APACHE II score, and 3-month mRS score (all p < 0.05). On multivariate analysis, disease-related stigma was associated with female sex (OR = 3.72, 95 % CI = 1.23-11.25, p = 0.02) and 3-month Barthel Index <100 (OR = 3.46, 95 % CI = 1.13-10.64, p = 0.03) on one model, and female sex (OR = 3.75, 95 % CI = 1.21-11.58, p = 0.02) and 3-month mRS score 3-5 (OR = 4.23, 95 % CI = 1.21-14.75, p = 0.02) on a second model. CONCLUSION/CONCLUSIONS:Functional outcome and female sex are associated with disease-related stigma 3-months after hemorrhagic stroke. Because stigma may negatively affect recovery, there is a need to understand the relationship between these factors to mitigate stroke-related stigma.

BACKGROUND AND PURPOSE/UNASSIGNED:Sleep disturbance after hemorrhagic stroke (intracerebral or subarachnoid hemorrhage) can impact rehabilitation, recovery, and quality of life. We sought to explore preclinical and clinical factors associated with sleep disturbance after hemorrhagic stroke assessed via the Quality of Life in Neurological Disorders (Neuro-QoL) short form sleep disturbance inventory. METHODS/UNASSIGNED:We telephonically completed the Neuro-QoL short form sleep disturbance inventory 3-months and 12-months after hemorrhagic stroke for patients >18-years-old hospitalized between January 2015 and February 2021. We examined the relationship between sleep disturbance (T-score >50) and social and neuropsychiatric history, systemic and neurological illness severity, medical complications, and temporality. RESULTS/UNASSIGNED:= .046). CONCLUSION/UNASSIGNED:This exploratory analysis did not demonstrate a sustained relationship between any preclinical or clinical factors and sleep disturbance after hemorrhagic stroke. Larger studies that include comparison to patients with ischemic stroke and healthy individuals and utilize additional techniques to evaluate sleep disturbance are needed.

OBJECTIVE:To examine the usefulness of carotid web (CW), carotid bifurcation and their combined angioarchitectural measurements in assessing stroke risk. METHODS:Anatomic data on the internal carotid artery (ICA), common carotid artery (CCA), and the CW were gathered as part of a retrospective study from symptomatic (stroke) and asymptomatic (nonstroke) patients with CW. We built a model of stroke risk using principal-component analysis, Firth regression trained with 5-fold cross-validation, and heuristic binary cutoffs based on the Minimal Description Length principle. RESULTS:The study included 22 patients, with a mean age of 55.9 ± 12.8 years; 72.9% were female. Eleven patients experienced an ischemic stroke. The first 2 principal components distinguished between patients with stroke and patients without stroke. The model showed that ICA-pouch tip angle (P = 0.036), CCA-pouch tip angle (P = 0.036), ICA web-pouch angle (P = 0.036), and CCA web-pouch angle (P = 0.036) are the most important features associated with stroke risk. Conversely, CCA and ICA anatomy (diameter and angle) were not found to be risk factors. CONCLUSIONS:This pilot study shows that using data from computed tomography angiography, carotid bifurcation, and CW angioarchitecture may be used to assess stroke risk, allowing physicians to tailor care for each patient according to risk stratification.

OBJECTIVE/UNASSIGNED:Emotional and behavioral dyscontrol (EBD), a neuropsychiatric complication of stroke, leads to patient and caregiver distress and challenges to rehabilitation. Studies of neuropsychiatric sequelae in stroke are heavily weighted toward ischemic stroke. This study was designed to compare risk of EBD following intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH) and to identify risk factors for EBD following hemorrhagic stroke. METHODS/UNASSIGNED:The authors conducted a prospective cohort study of patients hospitalized for nontraumatic hemorrhagic stroke between 2015 and 2021. Patients or legally authorized representatives completed the Quality of Life in Neurological Disorders (Neuro-QOL) EBD short-form inventory 3 months after hospitalization. Univariable and multivariable analyses identified risk factors for EBD after hemorrhagic stroke. RESULTS/UNASSIGNED:The incidence of EBD was 21% (N=15 of 72 patients) at 3 months after hemorrhagic stroke. Patients with ICH were more likely to develop EBD; 93% of patients with EBD (N=14 of 15) had ICH compared with 56% of patients without EBD (N=32 of 57). The median Glasgow Coma Scale (GCS) score at hospital admission was lower among patients who developed EBD (13 vs. 15 among those without EBD). Similarly, admission scores on the National Institutes of Health Stroke Scale (NIHSS) and the Acute Physiology and Chronic Health Evaluation II (APACHE II) were higher among patients with EBD (median NIHSS score: 7 vs. 2; median APACHE II score: 17 vs. 11). Multivariable analyses identified hemorrhage type (ICH) and poor admission GCS score as predictors of EBD 3 months after hemorrhagic stroke. CONCLUSIONS/UNASSIGNED:Patients with ICH and a low GCS score at admission are at increased risk of developing EBD 3 months after hemorrhagic stroke and may benefit from early intervention.

OBJECTIVE/UNASSIGNED:A significant number of patients develop anxiety after stroke. The objective of this study was to identify risk factors for anxiety after hemorrhagic stroke that may facilitate diagnosis and treatment. METHODS/UNASSIGNED:Patients admitted between January 2015 and February 2021 with nontraumatic hemorrhagic stroke (intracerebral [ICH] or subarachnoid [SAH] hemorrhage) were assessed telephonically 3 and 12 months after stroke with the Quality of Life in Neurological Disorders Anxiety Short Form to evaluate the relationships between poststroke anxiety (T score >50) and preclinical social and neuropsychiatric history, systemic and neurological illness severity, and in-hospital complications. RESULTS/UNASSIGNED:Of 71 patients who completed the 3-month assessment, 28 (39%) had anxiety. There was a difference in Glasgow Coma Scale (GCS) scores on admission between patients with anxiety (median=14, interquartile range [IQR]=12-15) and those without anxiety (median=15, IQR=14-15) (p=0.034), and the incidence of anxiety was higher among patients with ICH (50%) than among those with SAH (20%) (p=0.021). Among patients with ICH, anxiety was associated with larger median ICH volume (25 cc [IQR=8-46] versus 8 cc [IQR=3-13], p=0.021) and higher median ICH score (2 [IQR=1-3] versus 1 [IQR=0-1], p=0.037). On multivariable analysis with GCS score, hemorrhage type, and neuropsychiatric history, only hemorrhage type remained significant (odds ratio=3.77, 95% CI=1.19-12.05, p=0.024). Of the 39 patients who completed the 12-month assessment, 12 (31%) had anxiety, and there was a difference in mean National Institutes of Health Stroke Scale scores between patients with (5 [IQR=3-12]) and without (2 [IQR=0-4]) anxiety (p=0.045). There was fair agreement (κ=0.38) between the presence of anxiety at 3 and 12 months. CONCLUSIONS/UNASSIGNED:Hemorrhage characteristics and factors assessed with neurological examination on admission are associated with the development of poststroke anxiety.

BACKGROUND:Neurology faculty care for complex patients, teach, and work within multidisciplinary teams. It is imperative for faculty to have strong communication skills. METHODS:We surveyed NYU neurology teaching faculty to determine levels of comfort and experience over the past year with providing negative feedback to a trainee; debriefing after an adverse clinical outcome; and assisting a struggling colleague. We examined the relationship between levels of comfort and experience with 1) faculty self-identified sex and 2) number of years since completion of medical training. RESULTS:The survey was completed by 36/83 teaching neurology faculty (43 %); 17 (47 %) respondents were female and 21 (58 %) were ≤10 years post-training. The proportions of faculty who reported feeling uncomfortable were 44 % (16/36) for assisting a struggling colleague, 28 % (10/36) for providing negative feedback, and 19 % (7/36) for debriefing an adverse outcome. Proportions of faculty who reported they had no experience were 75 % (27/36) for assisting a struggling colleague, 39 % (14/36) for debriefing an adverse clinical event, and 17 % (6/36) for providing negative feedback. Female respondents and faculty who were ≤10 years post-training were more likely to report feeling uncomfortable with assisting a struggling colleague and to have had no experience doing so in the past year. On multivariate analyses accounting for sex and experience, sex remained independently associated with feeling uncomfortable with assisting a struggling colleague (OR = 12.2, 95 % CI: 2.1-69.6, p = 0.005). CONCLUSION/CONCLUSIONS:Faculty development may be needed to improve comfort and experience with challenging communication-based interactions. Female faculty and faculty early in their careers may benefit most.

BACKGROUND AND PURPOSE/OBJECTIVE:In patients with dolichoectasia, it is uncertain how dilatation and/or elongation relate to each other. We aimed to examine the correlation between arterial diameter and length within arteries and across the circle of Willis (COW). METHODS:We included stroke-free participants in the Northern Manhattan Study who underwent magnetic resonance angiography. Intracranial artery diameters and lengths were obtained with semiautomated commercial software and were adjusted for head size. We first investigated the correlation between diameters and length using Pearson's correlation coefficient. We then built generalized linear models adjusted for demographics and risk factors. RESULTS:Among 1210 participants included in the analysis (mean age 71 ± 9 years, 59% women, 65% Hispanic), a larger basilar artery (BA) diameter correlated with greater BA length (r = .3), and left and right middle cerebral artery (MCA) diameters correlated with one another (r = .4). Across the COW, BA diameter correlated with MCA diameters (r = .3 for both). In adjusted analyses, MCA diameters were associated with larger posterior circulation diameters (β = 0.07), MCA and BA lengths (β = 0.003 and β = 0.002, respectively), presence of fetal posterior cerebral artery (PCA), (β = 0.11), and a complete COW (β = -0.02). Similarly, BA length was associated with a fetal PCA (β = 1.1), and BA diameter was associated with anterior circulation diameters (β = 0.15) and presence of fetal PCA (β = -0.4). CONCLUSIONS:COW configuration should be considered when using arterial diameter cutoffs to define dolichoectasia. Further studies are needed to discern whether arterial diameter or length best identify individuals at risk of vascular events attributable to dolichoectasia.
