Abstract
BACKGROUND AND OBJECTIVES Stroke mortality is more common in low-income and middle-income nations such as Mexico. Prognosis data typically rely on short-term hospital follow-ups, revealing high mortality rates due to systemic complications and early recurrence. We aim to explore stroke's long-term impact by examining all-cause and cause-specific mortality. METHODS We analyzed data from the Mexico City Prospective Study (1998-2004) with known mortality outcomes until December 2022. Baseline variables were compared between participants who had stroke and nonstroke participants. Cox proportional hazard regression assessed each variable's contribution to overall mortality. Subsequent analysis within the stroke subgroup aimed to identify unique risk factors of mortality, using Cox regression models adjusted for age, sex, and time since stroke. RESULTS Among 145,537 eligible participants, 1,492 (1.0%) had a history of stroke. Participants who had stroke were older (57.58 vs 50.16, p < 0.001); had lower mean weekly income ($108.24 vs $176.14, p < 0.001); had higher alcohol intake and smoking frequency; and had more frequent comorbidities such as hypertension (48.9 vs 19.3%, p < 0.001), diabetes (23.4 vs 12.9%, p < 0.001), and ischemic heart disease (5.4 vs 1.0%, p < 0.001). They had a significantly increased risk of death from any cause (hazard ratio [HR] 2.59, 95% CI 2.37-2.83, p < 0.001). Deceased participants with stroke were more likely to be male, with a higher prevalence of diabetes, hypertension, and abnormal waist-hip index. Stroke increased the risk of death from cardiac (HR 3.56, 95% CI 3.02-4.19, p < 0.001), renal (HR 2.05, 95% CI 1.58-2.66, p < 0.001), and pulmonary (HR 2.29, 95% CI 1.79-2.92, p < 0.001) causes. DISCUSSION This study confirms stroke's association with higher mortality rates, especially from cardiac, renal, and pulmonary causes in Mexico. It underscores the elevated prevalence of cardiovascular comorbidities and adverse socioeconomic profiles among participants who had stroke and those who died with a history of stroke.

Abstract
BACKGROUND Knowledge of local contextual sex differences in the profile and outcome for stroke can improve service delivery. We aimed to determine sex differences in the profile of patients with acute stroke and their associations with in-hospital death in the national hospital database of Chile. METHODS AND RESULTS We present a retrospective cohort based on the analysis of the 2019 Chilean database of Diagnosis-Related Groups, which represents 70% of the operational expenditure of the public health system. Random-effects multiple logistic regression models were used to determine independent associations of acute stroke (defined by main diagnosis International Classification of Diseases, Tenth Revision [ICD-10] codes) and in-hospital death, and reported with odds ratios (ORs) and 95% CIs. Of 1 048 575 hospital discharges, 15 535 were for patients with acute stroke (7074 [45.5%] in women), and 2438 (15.6%) of them died during hospitalization. Differences by sex in sociodemographic and clinical characteristics were identified for stroke and main subtypes. After fully adjusted model, women with ischemic stroke had lower in-hospital death (OR, 0.79 [95% CI, 0.69-0.91]) compared with men; other independent predictors included age per year increase (OR, 1.03 [95% CI, 1.03-1.04]), chronic kidney disease (OR, 1.47 [95% CI, 1.20-1.80]), atrial fibrillation (OR, 1.50 [95% CI, 1.26-1.80]), and other risk factors. Conversely, for intracerebral hemorrhage, women had a higher in-hospital mortality rate than men (OR, 1.19 [95% CI, 1.02-1.40]); other independent predictors included age per year increase (OR, 1.009 [95% CI, 1.003-1.01]), chronic kidney disease (OR, 1.55 [95% CI, 1.23-1.97]), oral anticoagulant use (OR, 1.88 [95% CI, 1.37-2.58]), and other risk factors. CONCLUSIONS Sex differences in characteristics and in-hospital death of hospitalized patients exist for acute stroke in Chile. In-hospital death is higher for acute ischemic stroke in men and higher for intracerebral hemorrhage in women. Future research is needed to better identify contributing factors.

Risk Factors, Presentation, and Outcome in Acute Stroke according to Social Position Indicators in Patients Hospitalised in a Referral Centre in Bogotá 2011-2019. Neuroepidemiology 2023; 57:170-175. [PMID: 37454654 DOI: 10.1159/000529794] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Accepted: 02/13/2023] [Indexed: 07/18/2023] Open
Abstract
INTRODUCTION Treatment of stroke is time-dependent and it challenges patients' social and demographic context for timely consultation and effective access to reperfusion therapies. OBJECTIVE The objective of this study was to relate indicators of social position to cardiovascular risk factors, time of arrival, access to reperfusion therapy, and mortality in the setting of acute stroke. METHODS A retrospective analysis of patients with a diagnosis of ischaemic stroke in a referral hospital in Bogotá was performed. A simple random sample with a 5% margin of error and 95% confidence interval was selected. Patients were characterised according to educational level, place of origin, marital status, occupation, duration of symptoms before consultation, cardiovascular risk factors, access to reperfusion therapy, and mortality during hospitalisation. RESULTS 558 patients were included with a slight predominance of women. Diagnosis of diabetes was more common in women and smoking in men (n = 68, 28.4% vs. n = 51, 15.9%; p = 0.0004). Rural origin was associated with higher prevalence of hypertension, diabetes, and dyslipidaemia (hypertension n = 45, 73.8% vs. n = 282, 57.4%; p = 0.007; diabetes n = 20, 33.3% vs. 109, 19.5%; p = 0.02; dyslipidaemia n = 19, 32.7% vs. n = 93, 18.9%; p = 0.02). Mortality was higher in rural patients (n = 8, 14.2% vs. n = 30, 6.1%; p = 0.03). Lower schooling was associated with higher frequency of hypertension and dyslipidaemia (hypertension n = 152, 76.0% vs. n = 94, 46.3%; p ≤ 0.0001; dyslipidaemia n = 56, 28% vs. n = 35, 17.0%; p = 0.009) as well as with late consultation (n = 30, 15% vs. n = 59, 28.7%; p = 0.0011) and lower probability of accessing reperfusion therapy (n = 12, 6% vs. n = 45, 22%; p ≤ 0.0001). Formal employment was associated with a visit to the emergency department in less than 3 h (n = 50, 25.2% vs. n = 58, 18%, p = 0.04 and a higher probability of accessing reperfusion therapy (n = 35, 17.6% vs. n = 33, 10.2%; p = 0.01). Finally, living in a household with a stratum higher than 3 was associated with a consultation before 3 h (n = 77, 25.5% vs. n = 39, 15.6%; p = 0.004) and a higher probability of reperfusion therapy (n = 57, 18.9% vs. n = 13, 5.2%; p ≤ 0.0001). CONCLUSION Indicators of socio-economic status are related to mortality, consultation time, and access to reperfusion therapy. Mortality and reperfusion therapy are inequitably distributed and, therefore, more attention needs to be directed to the cause of these disparities in order to reduce the access gap in the context of acute stroke in Bogotá.

Ethnodemographic characterization of stroke incidence and burden of disease in hospital discharge records in Ecuador. Front Neurol 2023; 14:1059169. [PMID: 36846135 PMCID: PMC9945224 DOI: 10.3389/fneur.2023.1059169] [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: 10/01/2022] [Accepted: 01/16/2023] [Indexed: 02/11/2023] Open
Abstract
Introduction Stroke is the second most common cause of death and disability-adjusted life years (DALYs) globally. However, the incidence and impact of stroke by ethnicity and gender is frequently distinct. This is particularly the case in Ecuador where geographic and economic marginalization are often correlated with ethnic marginalization and the extent to which females lack the same opportunities as their male counterparts. The aim of this paper is to investigate the differential impacts in terms of stroke diagnosis and burden of disease by ethnicity and gender, using hospital discharge records over the years 2015-2020. Methods This paper calculates stroke incidence, and fatality rates using hospital discharge and death records over the years 2015-2020. The DALY package in R was employed to calculate the Disability Adjusted Life Years lost due to stroke in Ecuador. Results The results show that while the incidence rate of stroke in males (64.96 per 100,000 persons-year) is higher than that for females on average (57.84 per 100,000 persons-year), males accounted for 52.41% of all stroke cases and 53% of all surviving cases. Thus, hospital data suggests that females had a higher death rate when compared to males. Case fatality rates also differed significantly by ethnicity. The highest fatality rate corresponded to the Montubio ethnic group (87.65%), followed by Afrodescendants (67.21%). The estimated burden of disease of stroke calculated using Ecuadorian hospital records (2015-2020) varied from 1,468 to 2,991 DALY per 1,000 population on average. Discussion Differences in the burden of disease by ethnic group are likely to reflect differential access to care by region and socio-economic group, both of which are frequently correlated with ethnic composition in Ecuador. Equitable access to health services remains an important challenge in the country. The gender discrepancy in fatality rates suggests that there is a need for targeted educational campaigns to identify stroke signs early, especially in the female population.

Abstract
Introduction and Aim Stroke is a disease with high mortality and morbidity. Although studies are generally performed on all patients with stroke, it is known that gender has an effect on etiology and prognosis. This study aimed to determine the importance of clinical stroke scales and laboratory markers in determining the short-term prognosis of female patients with ischemic stroke of anterior circulation. Materials and Methods The study was planned as a retrospective and cross-sectional study. SEDAN score, the National Institutes of Health stroke scale (NIHSS), the Modified Rankin Scale (mRS), the Glasgow Coma Scale (GCS), and THRIVE score applied to the patients at the time of admission were recorded. Admission blood glucose, hemoglobin, leukocyte, urea, albumin, and blood lipid levels were evaluated. The relationship of all these parameters with in-hospital prognosis, mortality, and disability at discharge was examined. The relationship between groups and data was analyzed using the SPSS package program after the normality analysis. Results In this study, there were 733 female patients with stroke with a mean age of 69.53 ± 14.51 years and 858 male patients with stroke with a mean age of 64.27 ± 13.29 years. Hospitalization time, length of stay in the intensive care unit, ventilation need rate, mortality, and dependency rate were higher in female patients (p = 0.001). The NIHSS, SEDAN, and THRIVE scores were higher in female patients who had in-hospital mortality, had a poor prognosis, and who were discharged as dependent (p = 0.001). GCS was lower in this patient group (p = 0.001). Blood glucose, creatinine, leukocytes, urea, and CRP levels were higher; the albumin and hemoglobin levels was lower in female patients who had fatal outcomes (p = 0.009, 0.001, 0.001, 0.001, 0.001, and 0.020; respectively). In female patients who were dependent at discharge, blood urea, glucose, and CRP levels were higher and the albumin levels were lower than those in female patients who achieved functional independence (p = 0.001, 0.016, 0.002, and 0.001, respectively). Conclusion Our study showed that the short-term prognosis is worse in female patients who had an ischemic stroke of anterior circulation. It also revealed some clinical and laboratory parameters that could predict this situation. More intensive monitoring may be needed to improve prognosis in female patients.

Abstract
Background Whether patients with stroke and cancer exhibit specific characteristics has remained controversial. Methods Medical records of patients with ischemic stroke in 2014 or 2015 registered in the Swiss Stroke Registry of Zurich were retrospectively analyzed and integrated with regional cancer registry data. Associations of clinical and outcome parameters with cancer diagnosed up to 5 years prior to stroke were tested. Results Of 753 patients with ischemic stroke, 59 patients with cancer were identified. History of venous thromboembolism (p < 0.001) was associated with cancer while age and cardiovascular risk factors were not. Higher levels of D-dimers (p = 0.001), erythrocyte sedimentation rate (p = 0.003), C-reactive protein (CRP) (p < 0.001), and lower levels of hemoglobin (p = 0.003) were associated with cancer. For platelets, pathologically low (p = 0.034) or high levels (p < 0.001) were linked to cancer. Modified Rankin scale (mRS) scores ≥ 4 on admission and at follow-up were more frequent in cancer patients (p = 0.038 and p = 0.001). Poor post-stroke survival was associated with cancer (HR 2.2, p < 0.001). Multivariable analysis identified venous thromboembolism (OR 5.1), pathologic platelet count (OR = 2.9), low hemoglobin (OR 2.5) and elevated CRP (OR 1.8) as independently associated with cancer. In multivariable Cox regression, risk for death was associated with cancer (HR 1.7), low hemoglobin (HR 2.6), mRS on admission ≥ 4 (HR 1.9), pathologic platelet count (HR 1.6), female sex (HR 1.7), and elevated CRP (HR 1.4). Conclusions Considering cancer as a cofactor for post-stroke outcome may impact clinical decision making.

Abstract
BACKGROUND Posterior circulation stroke is characterized by poor prognosis because its optimal thrombolysis "time window" is always missed. After mechanical thrombectomy (MT), the recanalization rate of posterior circulation obstruction is significantly increased, but prognosis remains poor. To best manage patients, prognostic factors are needed to inform MT triaging after posterior circulation stroke. METHODS A systematic literature search was done for the period through April 2020. Studies included those with posterior circulation stroke cases that underwent MT. The primary outcome measure in this study was the modified Rankin Scale on day 90. RESULTS No outcome differences were found in gender, atrial fibrillation, smoking, and coronary artery disease (OR = 1.07, 95% CI: 0.90-1.28; OR = 1.02, 95% CI: 0.82-1.26; OR = 1.26, 95% CI: 0.94-1.68; and OR = 0.84, 95% CI: 0.58-1.22, respectively). Hypertension, diabetes mellitus, and previous stroke correlated with poorer prognosis (OR = 0.61, 95% CI: 0.48-0.77; OR = 0.60, 95% CI: 0.50-0.73; and OR = 0.74, 95% CI: 0.55-0.99, respectively). However, hyperlipidemia correlated with better prognosis (OR = 1.28, 95% CI: 1.04-1.58). CONCLUSION Our analysis indicates that hypertension, diabetes mellitus, or previous stroke correlate with poorer outcomes. Intriguingly, hyperlipidemia correlates with better prognosis. These factors may help inform triage decisions when considering MT for posterior circulation stroke patients. However, large, multicenter, randomized controlled trials are needed to validate these observations.

Abstract
Objectives: Stroke is a major cause of long-term disability and death worldwide. Several studies have shown that women in general have more severe symptoms at arrival to hospital and are less likely to return home and independent living. Our aim with the present study was to update previous results concerning sex differences in baseline characteristics, stroke management, and outcome in a population study from Sahlgrenska University Hospital, Gothenburg, Sweden. Methods: This study included patients with acute ischemic and hemorrhagic stroke in 2014 at Sahlgrenska University Hospital. All data were collected from The Swedish National Stroke Registry (Riksstroke). Results: The study population consisted of 1453 patients, with 46.7% females. Women were 5 years older than men. There was no sex difference in acute stroke severity. Frequency of revascularization was equal between men and women. The stroke mortality rate was the same between the sexes. At 3-months follow-up, women had a worse functional outcome and a higher frequency of depression and post-stroke fatigue. Conclusion: Our results show that there are no sex differences in management of acute stroke. However, the cause of worse functional outcome in women at 3-months follow-up, independent of other risk factors, is not clear and warrants further investigations.

Abstract
Background Reports on sex differences in stroke outcome and risk factors are scarce in Latin America. Our objective was to analyze clinical and prognostic differences according to sex among participants in the LASE (Latin American Stroke Registry). Methods and Results Nineteen centers across Central and South America compiled data on demographics, vascular risk factors, clinical stroke description, ancillary tests, and functional outcomes at short‐term follow‐up of patients included from January 2012 to January 2017. For the present study, all these variables were analyzed according to sex at hospital discharge. We included 4788 patients with a median in‐hospital stay of 8 days (interquartile range, 5–8); 2677 were male (median age, 66 years) and 2111 female (median age, 60 years). Ischemic stroke occurred in 4293: 3686 as cerebral infarction (77%) and 607 as transient ischemic attack cases (12.7%); 495 patients (10.3%) corresponded to intracerebral hemorrhage. Poor functional outcome (modified Rankin scale, 3–6) was present in 1662 (34.7%) patients and 38.2% of women (P<0.001). Mortality was present in 6.8% of the registry, with 7.8% in women compared with 6.0% in men (P=0.01). Death and poor functional outcome for all‐type stroke showed a higher risk in female patients (hazard ratio, 1.3, P=0.03; and hazard ratio, 1.1, P=0.001, respectively). Conclusions A worse functional outcome and higher mortality rates occurred in women compared with men in the LASE, confirming sex differences issues at short‐term follow‐up.
