Survivorship After Neurocritical Care: A Scoping Review of Outcomes Beyond Physical Status. Neurocrit Care 2024:10.1007/s12028-024-01965-9. [PMID: 38622487 DOI: 10.1007/s12028-024-01965-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Accepted: 02/21/2024] [Indexed: 04/17/2024]
Abstract
Following intensive care unit hospitalization, survivors of acute neurological injury often experience debilitating short-term and long-term impairments. Although the physical/motor impairments experienced by survivors of acute neurological injury have been described extensively, fewer studies have examined cognitive, mental health, health-related quality of life (HRQoL), and employment outcomes. This scoping review describes the publication landscape beyond physical and/or motor sequelae in neurocritical care survivors. Databases were searched for terms related to critical illness, intensive care, and outcomes from January 1970 to March 2022. English-language studies of critically ill adults with a primary neurological diagnosis were included if they reported on at least one outcome of interest: cognition, mental health, HRQoL or employment. Data extraction was performed in duplicate for prespecified variables related to study outcomes. Of 16,036 abstracts screened, 74 citations were identified for inclusion. The studies encompassed seven worldwide regions and eight neurocritical diagnosis categories. Publications reporting outcomes of interest increased from 3 before the year 2000 to 71 after. Follow-up time points included ≤ 1 (n = 15 [20%] citations), 3 (n = 28 [38%]), 6 (n = 28 [38%]), and 12 (n = 21 [28%]) months and 1 to 5 (n = 19 [26%]) and > 5 years (n = 8 [11%]), with 28 (38%) citations evaluating outcomes at multiple time points. Sixty-six assessment tools were used to evaluate the four outcomes of interest: 22 evaluating HRQoL (56 [76%] citations), 21 evaluating cognition (20 [27%] citations), 21 evaluating mental health (18 [24%] citations), and 2 evaluating employment (9 [12%] citations). This scoping review aimed to better understand the literature landscape regarding nonphysical outcomes in survivors of neurocritical care. Although a rising number of publications highlight growing awareness, future efforts are needed to improve study consistency and comparability and characterize outcomes in a disease-specific manner, including outlining of a minimum core outcomes set and associated assessment tools.

Pioglitazone in spontaneous subarachnoid hemorrhage: study protocol of a multicenter, double-blind, randomized trial (PSSH). Front Pharmacol 2024; 14:1323292. [PMID: 38249343 PMCID: PMC10796591 DOI: 10.3389/fphar.2023.1323292] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Accepted: 12/18/2023] [Indexed: 01/23/2024] Open
Abstract
Introduction: Spontaneous subarachnoid hemorrhage (SAH), is a disorder that may be fatal and is primarily caused by a ruptured brain aneurysm. Despite significant leaps forward in the methods to produce aneurysms, the long-term outcomes did not much improve. Pioglitazone is a medication that has been authorized by the FDA as an agonist for the peroxisome proliferator-activated receptor-gamma (PPARγ). Pioglitazone or PPARγ has neuroprotective benefits in animal experiments both during and after traumatic brain injury (TBI) and SAH. Nevertheless, the treatment impact of Pioglitazone on humans is still unknown at this time. As a result, we will conduct a randomized, double-blind, placebo-controlled trial to explore the impact of pioglitazone on SAH. Methods/Design: This trial will recruit 400 patients with SAH from four Chinese hospitals. These patients will be equally and randomly assigned to Pioglitazone and placebo control groups for up to 30 days. Scores on the modified Rankin scale (mRS) are the primary outcomes. The secondary outcomes are a 30-day all-cause mortality rate, 6 months of Montreal cognitive assessment (Mo-CA), delayed cerebral ischemia, the requirement for intensive care, the incidence of sepsis, etc. All serious adverse events (SAEs) were recorded during the hospital. Every primary and safety analysis was conducted based on the intention-to-treat technique. The participants were given either a matching placebo or 15 mg of pioglitazone, with dose titrated to a target of 45 mg daily. Data on the therapeutic use of pioglitazone after SAH will be provided as a consequence of the findings of this experiment. In addition, this pilot trial is the first to prospectively investigate the effectiveness and safety of pioglitazone in patients with SAH. Ethics and dissemination: Ethics approval was obtained from the Medical Ethics Committee of 904th Hospital of Joint Logistic Support Force of PLA (Wuxi Taihu Hospital, approval No. 20220701). The findings of the trial will be presented at conferences, discussed in relevant patient groups, and published in peer-reviewed journals. Clinical Trial Registration: clinicaltrials.gov, identifier ChiCTR2200062954.

Abstract
Subarachnoid hemorrhage (SAH) is a type of hemorrhagic stroke associated with high mortality and morbidity. The blood-brain-barrier (BBB) is a structure consisting primarily of cerebral microvascular endothelial cells, end feet of astrocytes, extracellular matrix, and pericytes. Post-SAH pathophysiology included early brain injury and delayed cerebral ischemia. BBB disruption was a critical mechanism of early brain injury and was associated with other pathophysiological events. These pathophysiological events may propel the development of secondary brain injury, known as delayed cerebral ischemia. Imaging advancements to measure BBB after SAH primarily focused on exploring innovative methods to predict clinical outcome, delayed cerebral ischemia, and delayed infarction related to delayed cerebral ischemia in acute periods. These predictions are based on detecting abnormal changes in BBB permeability. The parameters of BBB permeability are described by changes in computed tomography (CT) perfusion and magnetic resonance imaging (MRI). Kep seems to be a stable and sensitive indicator in CT perfusion, whereas Ktrans is a reliable parameter for dynamic contrast-enhanced MRI. Future prediction models that utilize both the volume of BBB disruption and stable parameters of BBB may be a promising direction to develop practical clinical tools. These tools could provide greater accuracy in predicting clinical outcome and risk of deterioration. Therapeutic interventional exploration targeting BBB disruption is also promising, considering the extended duration of post-SAH BBB disruption.

Common Data Elements for Unruptured Intracranial Aneurysm and Subarachnoid Hemorrhage Clinical Research: Recommendations from the Working Group on Long-Term Therapies. Neurocrit Care 2020; 30:79-86. [PMID: 31077078 DOI: 10.1007/s12028-019-00727-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/28/2023]
Abstract
OBJECTIVES The goal for the long-term therapies (LTT) working group (WG) of the Unruptured Intracranial Aneurysm (UIA) and Subarachnoid Hemorrhage (SAH) common data elements (CDEs) was to develop a comprehensive set of CDEs, data definitions, case report forms, and guidelines for use in UIA and SAH LTT clinical research, as part of a new joint effort between the National Institute of Neurological Disorders and Stroke (NINDS) and the National Library of Medicine of the US National Institutes of Health. These UIA and SAH CDEs will join other neurological disease-specific CDEs already developed and available for use by research investigators. METHODS The eight LTT WG members comprised international UIA, and SAH experts reviewed existing NINDS CDEs and instruments, created new elements when needed, and provided recommendations for future LTT clinical research. The recommendations were compiled, internally reviewed by the all UIA and SAH WGs and steering committee members. The NINDS CDE team also reviewed the final version before posting the SAH Version 1.0 CDE recommendations on the NINDS CDE website. RESULTS The NINDS UIA and SAH LTT CDEs and supporting documents are publicly available on the NINDS CDE ( https://www.commondataelements.ninds.nih.gov/#page=Default ) and NIH Repository ( https://cde.nlm.nih.gov/home ) websites. The subcommittee members discussed and reviewed various parameters, outcomes, and endpoints in UIA and SAH LTT studies. The following meetings with WG members, the LTT WG's recommendations are incorporated into the disease/injury-related events, assessments and examinations, and treatment/intervention data domains. CONCLUSIONS Noting gaps in the literature regarding medication and rehabilitation parameters in UIA and SAH clinical studies, the current CDE recommendations aim to arouse interest to explore the impact of medication and rehabilitation treatments and therapies and encourage the convergence of LTT clinical study parameters to develop a harmonized standard.

Abstract
BACKGROUND AND OBJECTIVES Cognitive disorders may be an early sign of neuropsychiatric disorders; however, it remains unclear whether the screening measures are interchangeable. The aim of this study was to contrast the most commonly used screening tools-Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA)-for early detection of neurocognitive disorder (NCD). RESEARCH DESIGN AND METHODS This study presents a descriptive systematic review and informative literature according to the Cochrane Foundation's guidelines. The keywords "Mini-Mental State Examination" and "Montreal Cognitive Assessment" were searched in the Web of Science, SciELO, and LILACS databases. RESULTS Fifty-one studies were selected including a total sample of 11,870 participants (8,360 clinical patients and 3,510 healthy controls). Most studies were published in the past 5 years using a cross-sectional design, carried out across the world. They were organized by age ranges (18-69 years and 20-89 years), years of schooling, and mental status (with and without mental and behavior disorders). Sixteen of 18 studies had participants aged 18-69 years, and 21 out of 33 studies within the older set suggested that the MoCA is a more sensitive tool for detecting NCD. DISCUSSION AND IMPLICATIONS Thirty-seven studies suggested that the MoCA is a more sensitive tool for NCD detection because it assesses executive function and visuospatial abilities. Some individuals who demonstrated normal cognitive function on the MMSE had lower performance on the MoCA. However, it seems necessary to establish different cutoffs based on years of schooling to avoid false positives. Future studies should contrast MoCA with other screening tools designed for NCD assessment.

Abstract
BACKGROUND Measures such as modified Rankin Scale (mRS) may not reflect cognitive outcome following aneurysmal subarachnoid hemorrhage. The aim of this study was to assess the relationship between functional outcome, measured by mRS, and cognition, measured by mini-mental state examination (MMSE), after aSAH. A secondary analysis evaluated the impact of delayed cerebral ischemia (DCI) on the proportion of patients who had cognitive impairment. METHODS We performed a post hoc analysis of the Clazosentan to Overcome Neurological Ischemia and Infarction Occurring After Subarachnoid Hemorrhage (CONSCIOUS-1) trial data. MMSE and mRS scores were compared using Kruskal-Wallis equality-of-populations rank test with pairwise comparison post hoc analysis. Cognitive impairment was defined as MMSE score <27. A stepwise logistic regression model evaluated whether DCI was a predictor of cognitive impairment. RESULTS CONSCIOUS-1 comprised 413 patients. Of these, 337 took an MMSE at their 12-week follow-up. Mean MMSE score was 27 with a median of 29 (range, 0-30; SD 5.4). There were no significant differences between MMSE scores of patients who had 12-week mRS scores of 0-2. On multivariate analysis, DCI was independently associated with cognitive impairment after aSAH. CONCLUSIONS Patients considered to have a good outcome on mRS had varying degrees of cognitive function on MMSE, whereas development of DCI was an independent predictor of cognitive impairment after aSAH. MMSE may not be sensitive enough to discern subtle defects in cognition, as the median score was 29 out of 30.

Abstract
Background Although coagulopathy have been proved to be a contributor to a poor outcome of aneurysmal subarachnoid hemorrhage (aSAH), the risk factors for triggering coagulation abnormalities have not been studied after aneurysm clipping. Methods We investigated risk factors of coagulopathy and analyzed the relationship between acute coagulopathy and outcome after aneurysm clipping. The clinical data of 137 patients with ruptured CA admitted to our institution was collected and retrospectively reviewed. Patient demographic data (age, sex), smoking, alcohol use, hypertension, diabetes, Hunt-Hess grade, Fisher grade, operation time, intraoperative total infusion volume, intraoperative blood loss, intraoperative transfusion, intraoperative hemostatic drug treatment, calcium reduction (preoperative free calcium concentration–postoperative free calcium concentration) were recorded. Coagulation was assessed within 24 h. Postoperative hemorrhage and infarction, deep venous thrombosis (DVT), and mortality were analyzed. Results Coagulopathy was detected in a total of 51 cases (group I), while not in 86 cases (group II). Univariable analysis demonstrated that age, smoking, alcohol use, intraoperative total infusion volume, intraoperative blood loss, intraoperative transfusion, and calcium reduction (≥ 1.2 mg/dl) were related to coagulopathy. Non-conditional logistic regression analysis showed that age [OR, 1.037 (95% CI, 1.001–1.074); p = 0.045] and calcium reduction (≥ 1.2 mg/dl) [OR, 5.509 (95% CI, 1.900–15.971); p = 0.002] were considered as the risk factors for coagulopathy. Hunt-Hess grade [OR, 2.641 (95% CI, 1.079–6.331); p = 0.033] and operation time [OR, 0.107 (95% CI, 1.012–0.928); p = 0.043] were considered as the risk factors for hypocoagulopathy. There were 6 cases (11.7%) with cerebral infarction in group I, while 6 cases (6.98%) in group II (χ2 = 0.918, p = 0.338). There were 4 cases (7.84%) with rebleeding in group I, while 5 cases (5.81%) in group II (χ2 = 0.215, p = 0.643). The mortality was 9.80% (5/51) in group I, while 1.16% (1/86) in group II (χ2 = 5.708, p = 0.017). DVT was not detected in all cases. Conclusions In conclusion, age (≥ 65 years) and calcium reduction (≥ 1.2 mg/dl) were considered as the risk factors for coagulopathy and have been proved to be associated with higher mortality after aneurysm clipping.

Abstract
Objective Repeated testing using the Montreal Cognitive Assessment (MoCA) increases risks for practice effects which may bias measurements of cognitive change. The objective of this study is to develop two alternate versions of the MoCA (Hong Kong version; HK-MoCA) and to investigate the validity and reliability of the alternate versions in patients with DSM-5 Mild Neurocognitive Disorder (Mild NCD) and cognitively healthy controls. Methods Concurrent validity and inter-scale agreement were examined by Pearson correlation of the total scores between the original and alternate versions and the Bland-Altman Method. Criterion validity of the two alternate versions in differentiating patients with Mild NCD was tested using receiver operating characteristic curve (ROC) analysis. One-month test-retest and inter-rater reliability were examined in 20 participants. Internal consistency of the alternate versions was measured by the Cronbach’s α. Results 30 controls (age 73.4 [4.5] years, 60% female) and 30 patients (age 75.4 [5.5] years, 73% female) with Mild NCD were recruited. Both alternate versions significantly correlated with the original version (r = 0.79–0.87, p<0.001). Mean differences of 0.17 and -0.40 points were found between the total scores of the alternate with the original versions with a consistent level of agreement observed throughout the range of cognitive abilities. Both alternate versions significantly differentiated patients with Mild NCD from healthy controls (area under ROC 0.922 and 0.724, p<0.001) and showed good one-month test-retest reliability (intra-class correlation [ICC] = 0.92 and 0.82) and inter-rater reliability (ICC = 0.99 and 0.87) and high internal consistency (Cronbach α = 0.79 and 0.75). Conclusion The two alternate versions of the HK-MoCA are useful for Mild NCD screening.

Abstract
BACKGROUND Simvastatin might be beneficial to the patients with aneurysmal subarachnoid hemorrhage. However, the results remained controversial. We conducted a systematic review and meta-analysis to explore the efficacy of simvastatin for aneurysmal subarachnoid hemorrhage. METHODS PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases were systematically searched. Randomized controlled trials (RCTs) assessing the effect of simvastatin versus placebo on aneurysmal subarachnoid hemorrhage were included. Two investigators independently searched articles, extracted data, and assessed the quality of included studies. The primary outcomes were delayed ischaemic deficit and delayed cerebral infarction. Meta-analysis was performed using the random-effect model. RESULTS Six RCTs involving 1053 patients were included in the meta-analysis. Overall, compared with control intervention, simvastatin intervention had no influence on delayed ischaemic deficit (RR=0.99; 95% CI=0.78 to 1.27; P=0.96), delayed cerebral infarction (RR=1.17; 95% CI=0.60 to 2.29; P=0.65), mRS≤2 (RR=0.97; 95% CI=0.87 to 1.09; P=0.61), vasospasm (RR=0.79; 95% CI=0.49 to 1.29; P=0.35), ICU stay (Std. mean difference=0.04; 95% CI=-0.54 to 0.63; P=0.88), hospital stay (Std. mean difference=0.01; 95% CI=-0.13 to 0.14; P=0.90) and mortality (RR=0.71; 95% CI=0.25 to 2.05; P=0.53) after aneurysmal subarachnoid hemorrhage. CONCLUSIONS Compared to control intervention, simvastatin intervention was found to have no influence on delayed ischaemic deficit, delayed cerebral infarction, mRS≤2, vasospasm, ICU stay, hospital stay, and mortality in patients with acute aneurysmal subarachnoid hemorrhage.

Abstract
OBJECTIVE The efficacy of statin therapy in treating aneurysmal subarachnoid hemorrhage (SAH) remains controversial. In this meta-analysis, the authors investigated whether statin treatment significantly reduced the incidence of cerebral vasospasm and delayed neurological deficits, promoting a better outcome after aneurysmal SAH. METHODS A literature search of the PubMed, Ovid, and Cochrane Library databases was performed for randomized controlled trials (RCTs) and prospective cohort studies investigating the effect of statin treatment. The end points of cerebral vasospasm, delayed ischemic neurological deficit (DIND), delayed cerebral infarction, mortality, and favorable outcome were statistically analyzed. RESULTS Six RCTs and 2 prospective cohort studies met the eligibility criteria, and a total of 1461 patients were included. The meta-analysis demonstrated a significant decrease in the incidence of cerebral vasospasm (relative risk [RR] 0.76, 95% confidence interval [CI] 0.61-0.96) in patients treated with statins after aneurysmal SAH. However, no significant benefit was observed for DIND (RR 0.88, 95% CI 0.70-1.12), delayed cerebral infarction (RR 0.66, 95% CI 0.33-1.31), mortality (RR 0.69, 95% CI 0.39-1.24) or favorable outcome, according to assessment by the modified Rankin Scale or Glasgow Outcome Scale (RR 0.99, 95% CI 0.92-1.17). CONCLUSIONS Treatment with statins significantly decreased the occurrence of vasospasm after aneurysmal SAH. The incidence of DIND, delayed cerebral infarction, and mortality were not affected by statin treatment. Future research should focus on DIND and how statins influence DIND.
