Abstract
INTRODUCTION Aneurysmal subarachnoid hemorrhage (SAH) is more common in women than in men, contrary to most cardiovascular diseases. However, it is unclear whether the case fatality rate (CFR) of SAH also differs by sex. Thus, we performed a systematic review to address the relationship between sex and SAH CFRs. METHODS We conducted a systematic literature search in PubMed, Scopus, and Cochrane library databases. We focused on population-based studies that included both nonhospitalized and hospitalized SAHs and had either reported 1-month (28-31 day) SAH CFRs separately for men and women or calculated risk estimates for SAH CFR by sex. For quality classification, we used the Cochrane Collaboration Handbook and Critical Appraisal Skills Program guidelines. We pooled the study cohorts and calculated relative risk ratios (RRs) with 95% confidence intervals (CIs) for SAH death between women and men using a random-effects meta-analysis model. RESULTS The literature search yielded 5,592 initial publications, of which 33 study cohorts were included in the final review. Of the 33 study cohorts, only three reported significant sex differences, although the findings were contradictory. In the pooled analysis of all 53,141 SAH cases (60.3% women) from 26 countries, the 1-month CFR did not differ (RR = 0.99 [95% CI: 0.93-1.05]) between women (35.5%) and men (35.0%). According to our risk-of-bias evaluation, all 33 study cohorts were categorized as low quality. The most important sources of bias risks were related to the absence of proper confounding control (all 33 study cohorts), insufficient sample size (27 of 33 study cohorts), and poor/unclear diagnostic accuracy (27 of 33 study cohorts). CONCLUSION Contrary to SAH incidence rates, the SAH CFRs do not seem to differ between men and women. However, since none of the studies were specifically designed to examine the sex differences in SAH CFRs, future studies on the topic are warranted.

Clin Neurol Neurosurg 2022; 220:107359. [PMID: 35835023 DOI: 10.1016/j.clineuro.2022.107359] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Revised: 06/22/2022] [Accepted: 07/03/2022] [Indexed: 11/18/2022]
Abstract
OBJECTIVE Gender differences in mortality after stroke remains unclear in the current literature. We therefore aimed to systematically review the gender differences in mortality up to five years after ischaemic (IS) or haemorrhagic stroke (HS) to address this evidence gap. METHODS The literature was systematically searched using Ovid EMBASE, Ovid Medline, and Web of Science databases, from inception-November 2021. The quality of evidence was appraised using the CASP Cohort-study checklist. Unadjusted and adjusted odds and hazard ratios were meta-analysed, separately for IS and HS and a subgroup analysis of age-stratified mortality data was conducted. RESULTS Forty-one studies were included (n = 8,128,700; mean-age 68.5 yrs; 47.1% female). 37 studies were included in meta-analysis (n = 8, 8008, 110). Compared to men, women who had an IS had lower mortality risk in-hospital (0.94; 95%CI 0.91-0.97), at one-month (0.87; 95%CI 0.77-0.98), 12-months (0.94; 95%CI 0.91-0.98) and five-years (0.93 95%CI 0.90-0.96). The subgroup analysis showed that this gender difference in mortality was present in women ≥ 70 years up to one-month post-IS (in-hospital: 0.94; 95%CI 0.91-0.97; one-month: 0.87; 95% CI 0.77-0.98), however, in women < 70 years this difference was no longer present. Nevertheless, analysis of crude data showed women were at higher risk of mortality in-hospital, at 12-months and five-years (in-hospital: 1.05; 95%CI 1.03-1.07, 12-months: 1.10; 95%CI 1.06-1.14, five-years: 1.06; 95%CI 1.02-1.10). After HS, women had higher mortality risk in-hospital (1.03; 95%CI 1.01-1.04) however, no gender differences were found post-discharge. CONCLUSION The gender differences in post-stroke mortality differ by stroke type, age group and follow-up. Crude stroke mortality in women is higher than in men and this appears to be driven by pre-existing comorbidities. In adjusted models, women have a lower mortality risk following IS, independent of duration of follow-up. After HS, women had higher mortality in hospital however, no gender differences after hospital discharge were found.

Abstract
INTRODUCTION Several differences have been reported between male and female patients with stroke in clinical and sociodemographic features, treatment, and outcomes. Potential effects in the inpatient rehabilitation population are unclear. OBJECTIVE To evaluate the differences between male and female patients in discharge functional status, length of stay, and discharge home after inpatient rehabilitation for stroke. DESIGN Retrospective, population-based cohort study. SETTING Inpatient rehabilitation centers in Ontario, Canada. PARTICIPANTS Male (N = 10,684) and female (N = 9459) patients discharged from acute care between September 1, 2012 and August 31, 2017, with a diagnosis of stroke and subsequently admitted to inpatient rehabilitation. EXPOSURE VARIABLE Female sex. MAIN OUTCOME MEASURES Discharge Functional Independence Measure (FIM) score, length of stay, and discharge home. RESULTS Female patients had a lower functional status at discharge (mean FIM score 94.1 vs. 97.8, p < .001) and a lower proportion were discharged home (81.1% vs. 82.9%, p = .001). Female and male patients had similar rehabilitation length of stay (mean 31.8 vs. 31.7 days, p = .90). In the adjusted analyses, there was no difference in discharge functional status between male and female patients (FIM score β -.20 [95% confidence interval [CI] -0.64 to 0.25]). Female patients had a mean length of stay 2% shorter (0.98 [95% CI 0.96-0.99]) and a higher odds of discharge home (odds ratio [OR] 1.14 [95% CI 1.05-1.24]). CONCLUSIONS There were no clinically significant sex differences in outcomes after inpatient rehabilitation for stroke. Observed sex disparities in the general stroke population may not be directly applicable to individuals undergoing inpatient rehabilitation.

Does the Occurrence of Particular Symptoms and Outcomes of Arterial Ischemic Stroke Depend on Sex in Pediatric Patients?-A Pilot Study. Brain Sci 2020; 10:brainsci10110881. [PMID: 33233638 PMCID: PMC7699743 DOI: 10.3390/brainsci10110881] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2020] [Revised: 11/06/2020] [Accepted: 11/19/2020] [Indexed: 12/23/2022] Open
Abstract
Arterial ischemic stroke (AIS) in childhood is reported to occur more frequently in boys, which may lead to the assumption that the prevalence of post-stroke deficits is sex related. The present study aimed to evaluate sex-related differences in functional outcomes (hemiparesis, seizures, aphasia, and motor disturbances other than hemiparesis) in pediatric patients with AIS. A total of 89 children (52 boys and 37 girls; mean age at stroke onset: 8.4 ± 5.6 years) were evaluated retrospectively based on data from medical records. The patients were divided into subgroups according to age (i.e., infants and toddlers, children, and adolescents), stroke subtype (i.e., lacunar anterior circulation infarct (LACI), total anterior circulation infarct (TACI), partial anterior circulation infarct (PACI), posterior circulation infarct (POCI)) and stroke location (i.e., anterior stroke, posterior stroke). Significant differences in the prevalence of stroke subtypes between girls and boys were observed (p = 0.034). POCI stroke were found to be more frequent in boys than in girls (OR = 8.57 95%CI 1.05–70.23, p = 0.023). Males predominated in the total group and in all analyzed age subgroups. The proportions of boys within the subgroups according to stroke subtype were extremely high for the POCI and TACI stroke subgroups. On the other hand, girls predominated in the LACI stroke subgroup. Frequency of central type facial nerve palsy and other symptoms of AIS were found to significantly differ between male subgroups according to stroke subtype (p = 0.050 and p < 0.001, respectively), as well as between children with anterior stroke and those with posterior stroke (p = 0.059 and p < 0.001, respectively). Post-stroke seizures appeared significantly more commonly in girls with TACI and POCI stroke than in girls with LACI and PACI stroke (p = 0.022). In turn, the prevalence of post-stroke hemiparesis differed between stroke subtypes in boys (p = 0.026). In conclusion, sex may have an impact in predisposing to a certain type of AIS in the patient. Post-stroke seizure may be related to stroke subtype in girls and hemiparesis in boys. However, further studies are needed to confirm the results.

Abstract
BACKGROUND Gender differences are often reported in the field of ischemic stroke, although most of such discrepancies were observed in randomized trials involving highly selected populations. We therefore explored gender differences regarding 90-day outcomes in large vessel occlusion (LVO) strokes receiving endovascular treatment in a real world setting. METHODS This prospective registry included anterior and/or posterior circulation LVO strokes admitted between January 2014 and December 2019 who received mechanical thrombectomy up to 24 hours from symptoms onset or last known to be well. We explored sex-related differences in rates of functional independence (modified Rankin Scale, mRS, ≤2) at 90 days. Secondary outcomes included "National Institutes of Health Stroke Scale" (NIHSS) at 24 hours, successful reperfusion defined as modified Thrombolysis in Cerebral Infarction (mTICI) scale 2b/3, death, and symptomatic intracranial hemorrhage (sICH). RESULTS A total of 288 LVO stroke patients comprised the study population, involving 148 (51.4%) women. Females were older (71.4±15.7 vs. 66.1±14.0 years, p=0.003) and had lower rates of coronary artery disease (15% vs. 24%, p=0.05). The median time from symptoms onset to hospital arrival was 315 min (IQR 139.5-495.0) in females and 255.0 (IQR 117.0-405.0) in males (p=0.052). Rates of mRS ≤2 at 90 days were comparable (females 46% vs. males 49%, p=0.50). Successful reperfusion was achieved in 82% of females and 89% of males (p=0.10). Rates of sICH (females 10% vs. males 13%, p=0.47) and death (females 18% vs. males 21%, p=0.50) at 90 days were similar. NIHSS at 24 hours was the strongest predictor of functional independence at 90 days (area under ROC curve 0.92 (95%CI 0.87; 0.95)]. CONCLUSIONS Our prospective registry involving a real world setting suggests that females are equally likely to achieve good outcomes after endovascular treatment despite being older and having delayed hospital arrival compared to males. In addition, we found that NIHSS at 24 hours was the strongest predictor of functional independence at 90 days, sICH, and death.

Abstract
Aim: This study investigated the clinical factors associated with functional ambulatory outcomes and gender differences in prestroke depressive patients. Materials & methods: Clinical risk factors associated with improved functional outcomes with recombinant tissue plasminogen activator-treated cohorts were determined using binary logistic regression. Results: In the adjusted analysis, improvement in ambulation was associated with male patients that had higher National Institute of Health stroke scale score (p = 0.04), a stroke history (p = 0.026), lower serum creatinine levels (p = 0.049) and were taking cholesterol reducing medication (p = 0.014). Improvement in females was associated with taking antidepressants (p = 0.027) and having lower National Institute of Health stroke scale score (p = 0.002). Conclusion: Our findings indicate gender disparities between male and female prestroke depressive patients.

Abstract
ABSTRACT:Background:Female stroke patients may experience poorer functional outcomes than males following inpatient rehabilitation.Methods:Data from Alberta inpatient stroke rehabilitation units were examined to determine: (1) the impact of sex on time to inpatient rehabilitation, functional gains (using the Functional Independence Measure (FIM)), length of stay (LOS), and discharge destination; (2) if sex was related to age at the time of stroke, stroke severity, and living arrangement at discharge from rehabilitation; and (3) whether patients’ age and preadmission living arrangement had an influence on LOS in rehabilitation or discharge destination.Results:Two thousand two hundred sixty-six adult stroke patients (1283 males and 983 females) were subcategorized as mild (FIM >80; n = 1155), moderate (FIM 40–80; n = 994), or severe (FIM <40; n = 117). Fifty-five percent of males (45.7% females) had mild stroke; 39.5% of males (49.5% females) had moderate stroke; and 5.5% of males (4.8% females) had severe stroke. Females were significantly older than males (p = 2.4 × 10−4). No sex difference existed in time from acute care to rehabilitation admission (p = 0.73) or in mean FIM change (p = 0.294). Mean LOS was longer for females than males (p=0.018). Males were more likely than females to be discharged home (p = 1.8 × 10−13). Further, male patients (p = 6.4 × 10−7) and those < 65 years (p = 1.4 × 10−23) were more likely to be discharged home without homecare.Conclusion:There are significant sex and age differences in LOS in rehabilitation and discharge destination of stroke patients. These differences may suggest that sex and age of the patient need to be considered in care planning.

Abstract
Introduction Mechanical thrombectomy has become the standard treatment for large vessel occlusion (LVO) in acute ischemic stroke (AIS) in well-selected patients. Although many devices and strategies exist, the use of a balloon-tip guide catheter (BGC) with stent-retriever (SR) may hold several advantages. We aim to assess the efficacy and identify predictors of technical success of this unique approach. Methods From our prospectively maintained database, we identified consecutive cases in which a BGC was used for stent-retriever thrombectomy in anterior circulation LVO between 2015 and 2016. Baseline and procedural characteristics were captured and analyzed. Predictors of technical and clinical outcomes were identified by multivariable logistic regression analysis. Results Ninety-three patients with AIS-LVO were treated with BGC-assisted mechanical thrombectomy. The mean age was 71 years old (SD 14), with 49.5% male (n=46). Pre-operative IV-tPA was administered in 55.9% (n=52) of cases. The most common location of occlusive thrombus was M1 (64.5%, n=60). Successful recanalization (mTICI=2b-3) was achieved in 86.0% (n=80) of cases while complete revascularization (mTICI-3) was achieved in 56.5% (n=52). There was a first-pass success rate of 52.7% (n=49). At discharge, 38.7% of the patients were functionally independent (mRS≤2). Multivariate analysis revealed that the middle cerebral artery location was strongly predictive of first-pass success, resulting in mTICI =2b revascularization (OR 7.10, p=0.018). Additionally, female gender (OR 2.85, p=0.042) and decreasing mTICI were associated with a poor clinical outcome (mRS≥4; OR 1.76, p=0.008). Conclusions BGC assistance in stent retrieval thrombectomy is safe and effective for AIS due to anterior circulation LVO. Further investigation is required to elucidate the optimal treatment strategy based on patient and disease characteristics.

Abstract
BackgroundIt is largely unknown whether functional outcomes after mechanical thrombectomy for large vessel occlusion (LVO) ischemic strokes differ by sex in non-clinical trial populations. We investigated sex differences in 90-day outcomes among ischemic stroke patients receiving mechanical thrombectomy.MethodsThis was a prospective cohort of adults treated with mechanical thrombectomy for LVO at a single academic comprehensive stroke center from July 2015 to April 2017. Data on independence (mRS ≤2) at hospital discharge and 90 days were collected prospectively. Multiple logistic regression was used to determine the association between sex and 90-day independence, first adjusting for demographics, pre-stroke mRS, and NIHSS, then by co-morbidities and time to thrombectomy, and finally by vessel recanalization and use of intravenous thrombolysis.ResultsWe included 279 patients, 52% of whom were female. Compared with males, females were older (median years (IQR) 81 (75–88) vs. 71.5 (60–81), P<0.001) and had higher baseline NIHSS (mean SD 18.2±7.5 vs . 16.0±7.1, P=0.02). Similar proportions of males and females had pre-stroke mRS ≤2 (73.3% vs.67.1%, P=0.27). In multivariate analyses, males and females had a similar likelihood of being independent at discharge (aOR 0.71 (95%CI 0.32 to 1.58)), but females were less likely to be independent at 90 days (aOR 0.37 95% CI 0.16 to 0.87).ConclusionsIn patients treated with mechanical thrombectomy for LVOs at a large comprehensive stroke center, females were less likely to be independent at 90 days. Future research should investigate contributors to poor outcomes post-discharge in females with LVOs, along with potential interventions to improve outcomes.

Abstract
The blood-brain barrier (BBB) has many important functions in maintaining the brain's immune-privileged status. Endothelial cells, astrocytes, and pericytes have important roles in preserving vasculature integrity. As we age, cell senescence can contribute to BBB compromise. The compromised BBB allows an influx of inflammatory cytokines to enter the brain. These cytokines lead to neuronal and glial damage. Ultimately, the functional changes within the brain can cause age-related disease. One of the most prominent age-related diseases is ischemic stroke. Stroke is the largest cause of disability and is third largest cause of mortality in the United States. The biggest risk factors for stroke, besides age, are results of the metabolic syndrome. The metabolic syndrome, if unchecked, quickly advances to outcomes that include diabetes, hypertension, cardiovascular disease, and obesity. The contribution from these comorbidities to BBB compromise is great. Some of the common molecular pathways activated include: endoplasmic reticulum stress, reactive oxygen species formation, and glutamate excitotoxicity. In this chapter, we examine how age-related changes to cells within the central nervous system interact with comorbidities. We then look at how comorbidities lead to increased risk for stroke through BBB disruption. Finally, we discuss key molecular pathways of interest with a focus on therapeutic targets that warrant further investigation.

Abstract
BACKGROUND A vast scientific literature has dealt with gender-specific risk for brain disorder. That field is evolving toward a consensus to the effect that the estrogen hormone family is outstandingly and uniquely neuroprotective. However, the epidemiology relevant to this general outlook remains piecemeal. METHOD The present investigation strategically formats the relevant epidemiological findings around the world in order to quantitatively meta-analyze gender ratio of risk for a variety of relevant severe central nervous system (CNS) diseases at all three gonadal stages of the life cycle, pre pubertal, post adolescent/pre menopausal, and post menopausal. RESULTS The data quantitatively establish that (1) no single epidemiological study should be cited as evidence of gender-specific neuroprotection against the most common severe CNS diseases because the gender-specific risk ratios are contradictory from one study to the other; (2) risk for severe CNS disease is indeed significantly gender-specific, but either gender can be protected: it depends on the disease, not at all on the age bracket. CONCLUSION Our assay of gender-specific risk for severe brain disease around the world has not been able to support the idea according to which any one gender-prevalent gonadal steroid hormone dominates as a neuroprotective agent at natural concentrations.
