Plasma Neurofilament Light Chain as a Biomarker for Poor Outcome After Aneurysmal Subarachnoid Hemorrhage. World Neurosurg 2024:S1878-8750(24)00972-0. [PMID: 38866237 DOI: 10.1016/j.wneu.2024.06.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2024] [Accepted: 06/05/2024] [Indexed: 06/14/2024]
Abstract
BACKGROUND Neurofilament light chain (NfL), a biomarker reflecting neuro-axonal damage, may be useful in improving clinical outcome prediction after aneurysmal subarachnoid hemorrhage (aSAH). We explore the robust and additional value of NfL to neurologic and radiologic grading scales in predicting poor outcome after aSAH. METHODS In this prospective cohort study conducted in a single tertiary center, blood samples were collected of aSAH patients within 24 hours after ictus and before endovascular/surgical intervention. The primary endpoint was poor outcome at 6 months' follow-up. Receiver operating curves (ROC), area under the curve (AUC, 95% CI) and model-fit (Nagelkerke R2) were calculated for NfL, neurologic grading scale (WFNS), modified Fisher, age ,and sex. A combined ROC and AUC were calculated for variables with an AUC ≥ 0.70. RESULTS A total of 66 (42%) had poor outcome. The AUC of NfL for poor outcome was 0.70 (0.62-0.78). Combining NfL and WFNS resulted in a slightly higher model fit and not-significantly higher AUC for predicting poor outcome (R2 0.51; AUC 0.86, 0.80-0.92) compared with WFNS alone. When patients were stratified according to hemorrhage severity, median NfL [IQR] levels were significantly higher in poor grade (14 [7-32] pg/mL) than good grade patients (7 [5-14] pg/mL). Within poor grade patients, median NfL [IQR] levels were significantly higher in non-survivors (19 [11-36] pg/mL) than survivors (7 [6-13] pg/mL). CONCLUSION In the entire aSAH cohort, plasma NfL has an acceptable predictive performance but does not improve clinical outcome prediction. However, NfL may have potential value in subgroups based on hemorrhage severity.

Abstract
Aneurysmal subarachnoid hemorrhage (aSAH) is a devastating neurologic disease with high mortality and disability. There have been global improvements in survival, which has contributed to the prevalence of patients living with long-term sequelae related to this disease. The focus of active research has traditionally centered on acute treatment to reduce mortality, but now there is a great need to study the course of short- and long-term recovery in these patients. In this narrative review, we aim to describe the core pillars in the preservation of cerebral function, prevention of complications, the recent literature studying neuroplasticity, and future directions for research to enhance recovery outcomes following aSAH.

Mapping geographic disparities in treatment and clinical outcomes of high-grade aneurysmal subarachnoid hemorrhage in the United States. J Neurointerv Surg 2024:jnis-2023-021330. [PMID: 38378239 DOI: 10.1136/jnis-2023-021330] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Accepted: 02/03/2024] [Indexed: 02/22/2024]
Abstract
BACKGROUND AND OBJECTIVE Although high-grade (Hunt and Hess 4 and 5) aneurysmal subarachnoid hemorrhage (aSAH) typically portends a poor prognosis, early and aggressive treatment has previously been demonstrated to confer a significant survival advantage. This study aims to evaluate geographic, demographic, and socioeconomic determinants of high-grade aSAH treatment in the United States. METHODS The National Inpatient Sample (NIS) was queried to identify adult high-grade aSAH hospitalizations during the period of 2015 to 2019 using the International Classification of Diseases, 10th Revision, Clinical Modification (ICD) codes. The primary clinical endpoint of this analysis was aneurysm treatment by surgical or endovascular intervention (SEI), while the exposure of interest was geographic region by census division. Favorable functional outcome (assessed by the dichotomous NIS-SAH Outcome Measure, or NIS-SOM) and in-hospital mortality were evaluated as secondary endpoints in treated and conservatively managed groups. RESULTS Among 99 460 aSAH patients identified, 36 795 (37.0%) were high-grade, and 9210 (25.0%) of these were treated by SEI. Following multivariable logistic regression analysis, determinants of treatment by SEI included female sex (adjusted OR (aOR) 1.42, 95% CI 1.35 to 1.51), transfer admission (aOR 1.18, 95% CI 1.12 to 1.25), private insurance (ref: government-sponsored insurance) (aOR 1.21, 95% CI 1.14 to 1.28), and government hospital ownership (ref: private ownership) (aOR 1.17, 95% CI 1.09 to 1.25), while increasing age (by decade) (aOR 0.93, 95% CI 0.91 to 0.95), increasing mortality risk (aOR 0.60, 95% CI 0.57 to 0.63), urban non-teaching hospital status (aOR 0.66, 95% CI 0.59 to 0.73), rural hospital location (aOR 0.13, 95% CI 0.7 to 0.25), small hospital bedsize (aOR 0.68, 95% CI 0.60 to 0.76), and geographic region (South Atlantic (aOR 0.72, 95% CI 0.63 to 0.83), East South Central (aOR 0.75, 95% CI 0.64 to 0.88), and Mountain (aOR 0.72, 95% CI 0.61 to 0.85)) were associated with a lower likelihood of treatment. High-grade aSAH patients treated by SEI experienced significantly greater rates of favorable functional outcomes (20.1% vs 17.3%; OR 1.20, 95% CI 1.13 to 1.28, P<0.001) and lower rates of mortality (25.8% vs 49.1%; OR 0.36, 95% CI 0.34 to 0.38, P<0.001) in comparison to those conservatively managed. CONCLUSION A complex interplay of demographic, socioeconomic, and geographic factors influence treatment patterns of high-grade aSAH in the United States.

Abstract
BACKGROUND Patients with spontaneous subarachnoid hemorrhage (SAH) frequently encounter cognitive dysfunction and mental health issues with negative effects on health-related quality of life (HR-QoL). Here, we aimed to describe the prevalence of cognitive deficits, mental health problems, and HR-QoL impairments 1 year after SAH. METHODS In this prospective observational study, 177 patients with SAH admitted to our neurointensive care unit over a time span of ten years followed the invitation for an in-person 1-year follow-up, including a standardized neuropsychological test battery. Mental health issues (anxiety and depression) and HR-QoL were evaluated using questionnaires (Hospital Anxiety and Depression Scale; 36-item Short Form questionnaire). Functional outcome was assessed with the modified Rankin Scale (mRS) score. RESULTS Patients were 54 years of age (interquartile range 47-62 years) and presented with a median Hunt and Hess score of 2 (interquartile range 1-3) at admission. Most patients (93%) achieved good functional 1-year outcomes (mRS score 0-2). Seventy-one percent of patients had deficits in at least one cognitive domain, with memory deficits being the most prevalent (51%), followed by deficits in executive functions (36%), visuoconstruction (34%), and attention (21%). Even patients with perimesencephalic SAH (18%) or with full functional recovery (mRS score = 0, 46%) had a comparable prevalence of cognitive deficits (61% and 60%, respectively). Symptoms of depression and anxiety were reported by 16% and 33% of patients, respectively. HR-QoL was impaired in 37% (55 of 147). Patients with cognitive deficits (p = 0.001) or mental health issues (p < 0.001) more frequently reported impaired HR-QoL. CONCLUSIONS Most patients with SAH have cognitive deficits and mental health issues 1 year after SAH. These deficits impair patients' quality of life.

Abstract
Traumatic subarachnoid hemorrhage (tSAH) is a critical condition that requires comprehensive management to optimize patient outcomes. Nursing care plays a key role in the overall management of patients with tSAH via various aspects of care, including neurological assessment, monitoring, intervention, and education. In this review, we aim to evaluate the significant contributions of nursing care in managing patients with tSAH. Nurses perform initial neurological assessments, including the glasgow coma scale, pupil reactivity, vital signs, and sensory-motor evaluations. These assessments provide valuable information for early identification of deteriorating neurological status and prompt intervention. Additionally, nurses closely monitor intracranial pressure (ICP), cerebral perfusion pressure, and other hemodynamic parameters, assisting in the prevention and timely detection of secondary brain injury. For example, some strategies to manage ICP include elevating the head of the bed, maintaining adequate oxygenation and ventilation, administering proper medications, and ensuring fluid and electrolyte balance. Also, through careful monitoring, early recognition, and appropriate preventive measures, nursing care could prevent complications, including infections, deep vein thrombosis, and pressure ulcers. Furthermore, nursing care extends beyond physical management and encompasses psychosocial support for patients and their families. Nurses establish therapeutic relationships, providing emotional support, education, and counseling to alleviate anxiety, address concerns, and facilitate coping mechanisms. Education regarding medication management, lifestyle modifications, and the importance of regular follow-up enhances patient compliance and promotes long-term recovery.

Lumbar puncture-verified subarachnoid hemorrhage: bleeding sources, need of radiological examination, and functional recovery. Acta Neurochir (Wien) 2023:10.1007/s00701-023-05640-4. [PMID: 37227503 DOI: 10.1007/s00701-023-05640-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2023] [Accepted: 05/15/2023] [Indexed: 05/26/2023]
Abstract
BACKGROUND The primary aim was to determine the diagnostic yield of vascular work-up, the clinical course during neurointensive care (NIC), and rate of functional recovery for patients with computed tomography (CT)-negative, lumbar puncture (LP)-verified SAH. METHODS In this retrospective study, 1280 patients with spontaneous SAH, treated at our NIC unit, Uppsala University Hospital, Sweden, between 2008 and 2018, were included. Demography, admission status, radiological examinations (CT angiography (CTA) and digital subtraction angiography (DSA)), treatments, and functional outcome (GOS-E) at 12 months were evaluated. RESULTS Eighty (6%) out of 1280 SAH patients were computed tomography (CT)-negative, LP-verified cases. Time between ictus and diagnosis was longer for the LP-verified SAH cohort in comparison to the CT-positive patients (median 3 vs 0 days, p < 0.001). One fifth of the LP-verified SAH patients exhibited an underlying vascular pathology (aneurysm/AVM), which was significantly less common than for the CT-verified SAH cohort (19% vs. 76%, p < 0.001). The CTA- and DSA-findings were consistent in all of the LP-verified cases. The LP-verified SAH patients exhibited a lower rate of delayed ischemic neurological deficits, but no difference in rebleeding rate, compared to the CT-verified cohort. At 1-year post-ictus, 89% of the LP-verified SAH patients had recovered favorably, but 45% of the cases did not reach good recovery. Having an underlying vascular pathology and an external ventricular drainage were associated with worse functional recovery (p = 0.02) in this cohort. CONCLUSIONS LP-verified SAH constituted a small proportion of the entire SAH population. Having an underlying vascular pathology was less frequent in this cohort, but still occurred in one out of five patients. Despite the small initial bleeding in the LP-verified cohort, many of these patients did not reach good recovery at 1 year, this calls for more attentive follow-up and rehabilitation in this cohort.
