Sex differences in quality of life after ischemic stroke

Comparing the EQ-5D-5L and stroke impact scale 2.0 in stroke patients: an analysis of measurement properties

BACKGROUND

Stroke has evolved to become a chronic disease and a major public health challenge. To adequately capture the full disease burden of stroke patients, the assessment of health-related quality of life (HRQoL) and thus the performance of respective measures is increasingly relevant. The aim of this analysis was to compare the measurement properties of two self-report instruments, the EQ-5D-5L and the Stroke Impact Scale 2.0.

METHODS

The data used for the analysis was derived from a quasi-experimental case management study for mildly to moderately affected incident stroke and transient ischemic attack (TIA) patients aged ≥ 18 in Germany. Data was collected patient-individually at 3, 6 and 12 months after initial stroke. The EQ-5D-5L and SIS 2.0 were compared in terms of feasibility, ceiling and floor effects, responsiveness and known-groups validity (Kruskal-Wallis H and Wilcoxon rank-sum test).

RESULTS

A response for all three follow-ups is available for n = 855 patients. The feasibility of the EQ-5D-5L is determined as good (completion rate: 96.4-96.6%, ≥ one item missing: 3.2 - 3.3%), whereas the SIS 2.0 is moderately feasible (overall completion rate: 44.9-46.1%, ≥ one item missing in domains: 4.7 - 28.7%). The SIS 2.0 shows substantial ceiling effects in comparable domains (physical function: 10.4 - 13%, others: 3.5-31.3%) which are mainly larger than ceiling effects in the EQ-5D-5L index (17.1-21.5%). In terms of responsiveness, the EQ-5D-5L shows small to moderate change while the SIS 2.0 presents with moderate to large responsiveness. The EQ-5D-5L index, mobility, usual activities and Visual Analogue Scale show known-groups validity (p < 0.05). Content-related domains of the SIS 2.0 show known-groups validity as well (p < 0.05). However, it is compromised in the emotion domain in both measures (p > 0.05).

CONCLUSIONS

The EQ-5D-5L seems to be slightly more suitable for this cohort. Nonetheless, the results of both measures indicate limited suitability for TIA patients. Large-scale studies concerning responsiveness and known-groups validity are encouraged.

A literature review of outcome and treatment options after acquired brain injury: Suggestions for adult offenders using knowledge from the general population

BACKGROUND

Acquired brain injury (ABI) is a major health problem, often with negative effects on behaviour and mental health as well as cognition. Prevalence of ABI is exceptionally high among offenders and increases their re-offending risk. Information on risk factors for ABI and its outcomes among offenders that could guide effective treatment for them is, nevertheless, scarce and dispersed. However, there is a more substantial literature about the general population that could inform work with brain-injured offenders, especially when selecting for samples or subgroups with similar relevant characteristics, such as lower socio-economic status (SES), pre-injury lower tested intelligence score (<85) and pre-injury mental health problems.

AIMS

To explore brain injury data from non-offender samples of otherwise similar socio-economic and mental health and ability characteristics to offenders then, first, to describe their untreated outcomes and, secondly, outcomes after frequently used interventions in these circumstances, noting factors associated with their effectiveness.

METHOD

Three databases were systematically searched for the years 2010-2022; first, using terms for brain injury or damage and cognitive (dys)function, mental health or quality of life. Second, in a separate search, we used these terms and terms for interventions and rehabilitation. In the second review, studies were selected for clear, distinguishable data on age, sex, SES and lifestyle factors to facilitate inferences for offenders. A narrative analytical approach was adopted for both reviews.

RESULTS

Samples with characteristics that are typical in offender groups, including lower SES, lower pre-injury intelligence quotient (<85), prior cognitive impairments and prior mental health problems, had poorer cognitive and behavioural outcomes following ABI than those without such additional problems, together with lower treatment adherence. With respect to treatment, adequate motivation and self-awareness were associated with better cognitive and behavioural outcomes than when these were low or absent, regardless of the outcome measured.

CONCLUSIONS

More complex pre-injury mental health problems and social disadvantages typical of offenders are associated with poorer post-brain injury recovery. This paper adds to practical knowledge by bringing together work that follows specific outcome trajectories. Overall, succesful ABI-interventions in the general population that aim at pre-injury difficulties comparable to those seen among offenders, show that personalising injury-specific treatments and taking account of these difficulties, maximised positive outcomes.

Estrogen's sex-specific effects on ischemic cell death and estrogen receptor mRNA expression in rat cortical organotypic explants

Estrogens, such as the biologically active 17-β estradiol (E2), regulate not only reproductive behaviors in adults, but also influence neurodevelopment and neuroprotection in both females and males. E2, contingent upon the timing and concentration of the therapy, is neuroprotective in female and male rodent models of stroke. In Vivo studies suggest that E2 may partially mediate this neuroprotection, particularly in the cortex, via ERα. In Vitro studies, utilizing a chemically induced ischemic injury in cortical explants from both sexes, suggest that ERα or ERβ signaling is needed to mediate the E2 protection. Since we know that the timing and concentration of E2 therapy may be sex-specific, we examined if E2 (1 nM) mediates neuroprotection when female and male cortical explants are separately isolated from postnatal day (PND) 3-4 rat. Changes in basal levels ERα, ERβ, and AR mRNA expression are compared across early post-natal development in the intact cortex and the corresponding days in vitro (DIV) for cortical explants. Following ischemic injury at 7 DIV, cell death and ERα, ERβ and AR mRNA expression was compared in female and male cortical explants. We provide evidence that E2-mediated protection is maintained in isolated cortical explants from females, but not male rats. In female cortical explants, the E2-mediated protection at 24 h occurs secondarily to a blunted transient increase in ERα mRNA at 12 h. These results suggest that cortical E2-mediated protection is influenced by sex and supports data to differentially treat females and males following ischemic injury.

Gait speed at the acute phase predicted health-related quality of life at 3 and 12 months after stroke: a prospective cohort study

OBJECTIVE

To investigate the association between acute-phase gait speed and health-related quality of life (HRQoL) at 3 and 12 months post-stroke.

DESIGN

Prospective cohort study.

SUBJECTS/PATIENTS

1,475 patients with first-ever ischaemic stroke.

METHODS

The patients were divided into 3 groups according to tertiles of gait speed, namely ≤0.8, 0.8-1.1, ≥1.1 m/s. Gait speed was assessed by the 10-m walking test within 2 weeks of hospitalization for acute stroke and before the rehabilitation programme. HRQoL measurements include the 3-level EuroQol five dimensions (EQ-5D-3L) index and EuroQoL visual analogue scale (EQ-VAS) scores. Linear and logistic regression analyses were used to identify associations between gait speed and HRQoL.

RESULTS

Adjusted for all covariates, the highest gait speed tertile group were associated with higher EQ-5D-3L index (B = 0.0303 and B = 0.0228, respectively, p < 0.001), and higher EQ-VAS (B = 3.3038 and B = 3.8877, respectively, p < 0.001), and lower odds of having problems with mobility (OR = 2.55 [95% CI: 0.141-0.458] and 0.485 [0.289-0.812], respectively, p < 0.01), self-care (OR = 0.328 [95% CI: 0.167-0.646] and 0.412 [0.217-0.784], respectively, p < 0.01), and usual activities (OR = 0.353 [95% CI: 0.211-0.590] and 0.325 [0.198-0.536], respectively, p < 0.0001) at 3 and 12 months, and pain/discomfort at 12 months (OR = 0.558 [95% CI:0.335-0.930], p < 0.05).

CONCLUSION

Acute-phase gait speed was predictive of post-stroke HRQoL at 3 and 12 months, especially when associated with domain-specific EQ-5D-3L.

Biopsychosocial factors associated with the state of disability after hemiparesis in the chronic phase of stroke: exploratory analysis based on the International Classification of Functioning, Disability and Health

OBJECTIVE

To identify the main biopsychosocial factors associated with disability level after stroke using the International Classification of Functioning, Disability and Health (ICF) model.

METHODS

A cross-sectional study was conducted with chronic stroke survivors. Disability was assessed using the World Health Disability Assessment Schedule 2.0. The independent variables were: Body functions: emotional functioning and whether the dominant upper limb was affected. For the Activities & Participation component, satisfaction regarding the execution of activities and participation were assessed using the SATIS-Stroke, as well as the locomotion ability for adults (ABILOCO), manual ability (ABILHAND) and the return to work. For environmental factors, income and facilitators and obstacles were assessed using the Measure of the Quality of the Environment (MQE). Personal factors: age and sex. Multiple Linear Regression was employed.

RESULTS

Limited locomotor ability (β = -0.281; t = -3.231 p = 0.002), dissatisfaction regarding activities and participation (β = -0.273; t = -3.070 p = 0.003), and the non-return to work (β = 0.162; t = 2.085 p = 0.04) were associated with disability.

CONCLUSION

The reduction in locomotor ability, dissatisfaction regarding activities and participation and the non-return to work were associated with disability in the chronic phase following a stroke.

Quality of Life After Intravenous Thrombolysis for Acute Ischemic Stroke: Results From the AcT Randomized Controlled Trial

BACKGROUND

Recent evidence from thrombolysis trials indicates the noninferiority of intravenous tenecteplase to intravenous alteplase with respect to good functional outcomes in patients with acute stroke. We examined whether the health-related quality of life (HRQOL) of patients with acute stroke differs by the type of thrombolysis treatment received. In addition, we examined the association between the modified Rankin Scale score 0 to 1 and HRQOL and patient-reported return to prebaseline stroke functioning at 90 days.

METHODS

Data were from all patients included in the AcT trial (Alteplase Compared to Tenecteplase), a pragmatic, registry-linked randomized trial comparing tenecteplase with alteplase. HRQOL at 90-day post-randomization was assessed using the 5-item EuroQOL questionnaire (EQ5D), which consists of 5 items and a visual analog scale (VAS). EQ5D index values were estimated from the EQ5D items using the time tradeoff approach based on Canadian norms. Tobit regression and quantile regression models were used to evaluate the adjusted effect of tenecteplase versus alteplase treatment on the EQ5D index values and VAS score, respectively. The association between return to prebaseline stroke functioning and the modified Rankin Scale score 0 to 1 and HRQOL was quantified using correlation coefficient (r) with 95% CI.

RESULTS

Of 1577 included in the intention-to-treat analysis patients, 1503 (95.3%) had complete data on the EQ5D. Of this, 769 (51.2%) were administered tenecteplase and 717 (47.7%) were female. The mean EQ5D VAS score and EQ5D index values were not significantly higher for those who received intravenous tenecteplase compared with those who received intravenous alteplase (P=0.10). Older age (P<0.01), more severe stroke assessed using the National Institutes of Health Stroke Scale (P<0.01), and longer stroke onset-to-needle time (P=0.004) were associated with lower EQ5D index and VAS scores. There was a strong association (r, 0.85 [95% CI, 0.81-0.89]) between patient-reported return to prebaseline functioning and modified Rankin Scale score 0 to 1 Similarly, there was a moderate association between return to prebaseline functioning and EQ5D index (r, 0.45 [95% CI, 0.40-0.49]) and EQ5D VAS scores (r, 0.42 [95% CI, 0.37-0.46]).

CONCLUSIONS

Although there is no differential effect of thrombolysis type on patient-reported global HRQOL and EQ 5D-5L index values in patients with acute stroke, sex- and age-related differences in HRQOL were noted in this study.

Risk factors and predictive markers of post-stroke cognitive decline-A mini review

Stroke is one of the top causes of death and disability worldwide. Cognitive impairments are found in more than 70% of individuals who have survived a stroke. Cognitive decline is a major contributor to disability, dependency, and morbidity. The prevalence and severity of dementia vary depending on different characteristics of the stroke and other clinical risk factors. Here we discuss the effects of stroke territory, patients' age, sex, cerebral blood flow, acute reperfusion therapy, and cognitive reserve of post-stroke cognitive decline. Potential predictive molecular and genetic biomarkers of post-stroke cognitive impairments are also discussed.

Functional neurological disorder is a feminist issue

Functional neurological disorder (FND) is a common and disabling disorder, often misunderstood by clinicians. Although viewed sceptically by some, FND is a diagnosis that can be made accurately, based on positive clinical signs, with clinical features that have remained stable for over 100 years. Despite some progress in the last decade, people with FND continue to suffer subtle and overt forms of discrimination by clinicians, researchers and the public. There is abundant evidence that disorders perceived as primarily affecting women are neglected in healthcare and medical research, and the course of FND mirrors this neglect. We outline the reasons why FND is a feminist issue, incorporating historical and contemporary clinical, research and social perspectives. We call for parity for FND in medical education, research and clinical service development so that people affected by FND can receive the care they need.

A systematic review and meta-analysis of health utility values among patients with ischemic stroke

Purpose

Ischemic stroke (IS) has a considerable impact on the health-related quality of life (HRQoL) of patients. A systematic review was conducted to summarize and synthesize the HRQoL reported from IS patients.

Methods

An electronic search was performed in PubMed, Web of Science, ScienceDirect, Embase, and Cochrane Library databases from inception to February 2022 for studies measuring utility values in IS patients. Basic information about the studies, patient characteristics, measurement of the utility values, and utility values were extracted and summarized. Utility values were pooled according to the time of evaluation, and disease severity was classified with modified Rankin Scale (mRS) scores. The quality of the studies was assessed according to key criteria recommended by the National Institute for Health and Care Excellence.

Results

A total of 39 studies comprising 30,853 participants were included in the study. Measured with EQ-5D-3L, the pooled utility values were 0.42 [95% confidential interval (CI): 0.13 to 0.71], 0.55 (95% CI: 0.43 to 0.68), 0.65 (95% CI: 0.52 to 0.78), 0.60 (95% CI: 0.43 to 0.78), and 0.67 (95% CI: 0.60 to 0.74) for patients diagnosed with IS within 1, 3, 6, 12, and 24 months or above among poststroke patients. Four studies reported utility values classified by mRS scores where synthesized estimates stratified by mRS scores ranged from 0.91 (95% CI: 0.85 to 0.97) for patients with an mRS score of 1 to-0.04 (95% CI:-0.18 to 0.11) for those with an mRS score of 5. As for the health dimension profiles, usual activity was the most impacted dimension, while self-care was the least impacted one.

Conclusion

This study indicated that the utility values in IS patients kept increasing from stroke onset and became relatively stabilized at 6 months poststroke. Health utility values decreased significantly as mRS scores increased. These results facilitate economic evaluations in utility retrieval and selection. Further exploration was required regarding the factors that affect the HRQoL of IS patients.

Sex and gender differences in acute stroke care: metrics, access to treatment and outcome. A territorial analysis of the Stroke Code System of Catalonia

INTRODUCTION

Previous studies have reported differences in the management and outcome of women stroke patients in comparison with men. We aim to analyze sex and gender differences in the medical assistance, access to treatment and outcome of acute stroke patients in Catalonia.

PATIENTS AND METHODS

Data were obtained from a prospective population-based registry of stroke code activations in Catalonia (CICAT) from January/2016 to December/2019. The registry includes demographic data, stroke severity, stroke subtype, reperfusion therapy, and time workflow. Centralized clinical outcome at 90 days was assessed in patients receiving reperfusion therapy.

RESULTS

A total of 23,371 stroke code activations were registered (54% men, 46% women). No differences in prehospital time metrics were observed. Women more frequently had a final diagnosis of stroke mimic, were older and had a previous worse functional situation. Among ischemic stroke patients, women had higher stroke severity and more frequently presented proximal large vessel occlusion. Women received more frequently reperfusion therapy (48.2% vs 43.1%, p < 0.001). Women tended to present a worse outcome at 90 days, especially for the group receiving only IVT (good outcome 56.7% vs 63.8%; p < 0.001), but not for the group of patients treated with IVT + MT or MT alone, although sex was not independently associated with clinical outcome in logistic regression analysis (OR 1.07; 95% CI, 0.94-1.23; p = 0.27) nor in the analysis after matching using the propensity score (OR 1.09; 95% CI, 0.97-1.22).

DISCUSSION AND CONCLUSION

We found some differences by sex in that acute stroke was more frequent in older women and the stroke severity was higher. We found no differences in medical assistance times, access to reperfusion treatment and early complications. Worse clinical outcome at 90 days in women was conditioned by stroke severity and older age, but not by sex itself.

Determinants of health-related quality of life after out-of-hospital cardiac arrest (OHCA): A systematic review

OBJECTIVE

With a growing number of out-of-hospital cardiac arrest (OHCA) survivors globally, the focus of OHCA management has now broadened to survivorship. An outcome central to survivorship is health-related quality of life (HRQoL). This systematic review aimed to synthesise evidence related to the determinants of HRQoL of OHCA survivors.

METHODS

We systematically searched MEDLINE, Embase, and Scopus from inception to 15 August 2022 to identify studies investigating the association of at least one determinant and HRQoL in adult OHCA survivors. All articles were independently reviewed by two investigators. We abstracted data pertaining to determinants and classified them using a well-established HRQoL theoretical framework - the Wilson and Cleary (revised) model.

RESULTS

31 articles assessing a total of 35 determinants were included. Determinants were classified into the five domains in the HRQoL model. 26 studies assessed determinants related to individual characteristics (n=3), 12 studied biological function (n=7), nine studied symptoms (n=3), 16 studied functioning (n=5), and 35 studied characteristics of the environment (n=17). In studies that included multivariable analyses, most reported that individual characteristics (older age, female sex), symptoms (anxiety, depression), and functioning (impaired neurocognitive function) were significantly associated with poorer HRQoL.

CONCLUSIONS

Individual characteristics, symptoms, and functioning played significant roles in explaining the variability in HRQoL. Significant non-modifiable determinants such as age and sex could be used to identify populations at risk of poorer HRQoL, while significant modifiable determinants such as psychological health and neurocognitive functioning could serve as targets for post-discharge screening and rehabilitation plans.

Sex differences in pain expressed by patients across diverse disease states: individual patient data meta-analysis of 33,957 participants in 10 randomized controlled trials

ABSTRACT

The experience of pain is determined by many factors and has a significant impact on quality of life. This study aimed to determine sex differences in pain prevalence and intensity reported by participants with diverse disease states in several large international clinical trials. Individual participant data meta-analysis was conducted using EuroQol-5 Dimension (EQ-5D) questionnaire pain data from randomised controlled trials published between January 2000 and January 2020 and undertaken by investigators at the George Institute for Global Health. Proportional odds logistic regression models, comparing pain scores between females and males and fitted with adjustments for age and randomized treatment, were pooled in a random-effects meta-analysis. In 10 trials involving 33,957 participants (38% females) with EQ-5D pain score data, the mean age ranged between 50 and 74. Pain was reported more frequently by females than males (47% vs 37%; P < 0.001). Females also reported greater levels of pain than males (adjusted odds ratio 1.41, 95% CI 1.24-1.61; P < 0.001). In stratified analyses, there were differences in pain by disease group (P for heterogeneity <0.001), but not by age group or region of recruitment. Females were more likely to report pain, and at a higher level, compared with males across diverse diseases, all ages, and geographical regions. This study reinforces the importance of reporting sex-disaggregated analysis to identify similarities and differences between females and males that reflect variable biology and may affect disease profiles and have implications for management.

Modification of the effects of age on clinical outcomes through management of lifestyle-related factors in patients with acute ischemic stroke

BACKGROUND AND PURPOSE

This study examined the association between age and clinical outcomes after ischemic stroke, and whether the effect of age on post-stroke outcomes can be modified by various factors.

METHODS

We included 12,171 patients with acute ischemic stroke, who were functionally independent before stroke onset, in a multicenter hospital-based study conducted in Fukuoka, Japan. Patients were categorized into six groups according to age: ≤ 45, 46-55, 56-65, 66-75, 76-85, and > 85 years. Logistic regression analysis was performed to estimate an odds ratio for poor functional outcome (modified Rankin scale score of 3-6 at 3 months) for each age group. Interaction effects of age and various factors were analyzed using a multivariable model.

RESULTS

The mean age of the patients was 70.3 ± 12.2 years, and 63.9% were men. Neurological deficits at onset were more severe in the older age groups. The odds ratio of poor functional outcome linearly increased (P for trend <0.001), even after adjusting for potential confounders. Sex, body mass index, hypertension, and diabetes mellitus significantly modified the effect of age on the outcome (P < 0.05). The unfavorable effect of older age was greater in female patients and those with low body weight, whereas the protective effect of younger age was smaller in patients with hypertension or diabetes mellitus.

CONCLUSIONS

Functional outcome worsened with age in patients with acute ischemic stroke, especially in females and those with low body weight, hypertension, or hyperglycemia.

Determinants of the quality of life in Egyptian patients with cerebrovascular stroke by using the stroke specific QoL questionnaire

Background

Stroke is a neurological disorder resulting from a sudden decline in blood flow to a localized area of the brain. It is the second most common cause of death and the third most common cause of disability worldwide. Quality of life (QOL) is increasingly being used as an outcome measure designed to evaluate the quality of care for patients with stroke.

Objective

The study aims to assess the quality of life of cerebrovascular stroke patients in Alexandria, Egypt.

Methods

A descriptive crossover study was held on 80 adult cerebrovascular stroke patients admitted to the stroke unit at (Elhadra) University Hospital, Neuropsychiatry Department, and the outpatient clinics at the Main University Hospital.

Result

The main result of study revealed that there was a highly significant relation between socio-demographic characteristics and the patient’s quality of life (QOL), especially age, employment status, and the monthly income, the overall QOL (P < 0.05).

Recommendation

The study recommended that design health education program to raise stroke patient QOL, design program to improve care giver attitude toward stroke patient, collaborative efforts among the governmental agencies to improve the educational level of the citizens, further studies to examine QOL on larger group of patients to generalize the results.

Sex differences in endovascular thrombectomy outcomes in large vessel occlusion: a propensity-matched analysis from the SELECT study

BACKGROUND

Sex disparities in acute ischemic stroke outcomes are well reported with IV thrombolysis. Despite several studies, there is still a lack of consensus on whether endovascular thrombectomy (EVT) outcomes differ between men and women.

OBJECTIVE

To compare sex differences in EVT outcomes at 90-day follow-up and assess whether progression in functional status from discharge to 90-day follow-up differs between men and women.

METHODS

From the Selection for Endovascular Treatment in Acute Ischemic Stroke (SELECT) prospective cohort study (2016-2018), adult men and women (≥18 years) with anterior circulation large vessel occlusion (internal carotid artery, middle cerebral artery M1/M2) treated with EVT up to 24 hours from last known well were matched using propensity scores. Discharge and 90-day modified Rankin Scale (mRS) scores were compared between men and women. Furthermore, we evaluated the improvement in mRS scores from discharge to 90 days in men and women using a repeated-measures, mixed-effects regression model.

RESULTS

Of 285 patients, 139 (48.8%) were women. Women were older with median (IQR) age 69 (57-81) years vs 64.5 (56-75), p=0.044, had smaller median perfusion deficits (Tmax >6 s) 109 vs 154 mL (p<0.001), and had better collaterals on CT angiography and CT perfusion but similar ischemic core size (relative cerebral blood flow <30%: 7.6 (0-25.2) vs 11.4 (0-38) mL, p=0.22). In 65 propensity-matched pairs, despite similar discharge functional independence rates (women: 42% vs men: 48%, aOR=0.55, 95% CI 0.18 to 1.69, p=0.30), women exhibited worse 90-day functional independence rates (women: 46% vs men: 60%, aOR=0.41, 95% CI 0.16 to 1.00, p=0.05). The reduction in mRS scores from discharge to 90 days also demonstrated a significantly larger improvement in men (discharge 2.49 and 90 days 1.88, improvement 0.61) than in women (discharge 2.52 and 90 days 2.44, improvement 0.08, p=0.036).

CONCLUSION

In a propensity-matched cohort from the SELECT study, women had similar discharge outcomes as men following EVT, but the improvement from discharge to 90 days was significantly worse in women, suggesting the influence of post-discharge factors. Further exploration of this phenomenon to identify target interventions is warranted.

Quality of life and mood disorders of mild to moderate stroke survivors in the early post-hospital discharge phase: a cross-sectional survey study

BACKGROUND

Exploring sociodemographic and disease characteristics that contribute to patient-reported outcomes can inform targeting of strategies to support recovery and adaptation to stroke. This study aimed to examine among a sample of stroke survivors at three months post-hospital discharge: (1) self-reported physical and mental health quality of life scores; (2) self-reported depressive and anxiety symptoms; and (3) sociodemographic and clinical predictors of these outcomes.

METHODS

This cross-sectional survey study recruited stroke survivors from eight hospitals in one Australian state. Adult survivors recently discharged from hospital stroke wards (within 3 months) were mailed a study information package and invited to complete a pen-and paper survey. Survey items assessed: quality of life (SF12v2), depression (PHQ-9), anxiety (GAD-7) and sociodemographic and clinical characteristics. Predictors were examined using multiple linear regression analysis.

RESULTS

Of the 1161 eligible patients who were posted a recruitment pack, 401 (35%) returned a completed survey. Participants reported a mean SF-12v2 Physical Composite Score (PCS) quality of life score of 44.09 (SD = 9.57); and a mean SF-12v2 Mental Composite Score (MCS) quality of life score of 46.84 (SD = 10.0). Approximately one third of participants (34%; n = 132) were classified as depressed (PHQ-9 ≥ 10); and 27% (n = 104) were classified as anxious (GAD-7 ≥ 8). Lower PCS was associated with being female, not employed and having a comorbid diagnosis of diabetes and atrial fibrillation. Lower MCS was associated with a history of transient ischemic attack (TIA). Males and those with higher levels of education, had greater odds of having lower depression severity; those with a history of TIA or diabetes had lower odds of having lower depression severity. Males had greater odds of having lower anxiety severity; those with a history of TIA had lower odds of having lower anxiety severity.

CONCLUSION

Sub-groups of stroke survivors may be at-risk of poorer quality of life and psychological morbidity in the early post-discharge phase. These findings support the role of early identification and prioritisation of at-risk survivors at discharge, as they may require modifications to standard hospital discharge processes tailored to their level of risk.

Gender differences in health-related quality of life and psychological distress among coronary patients: Does comorbidity matter? Results from the ESC EORP EUROASPIRE V registry

AIMS

This study aimed to provide an overview on contemporary gender differences in HRQoL/psychological distress and their relationship with comorbidity burden among European coronary heart disease (CHD) patients.

METHODS

Analyses were based on the cross-sectional ESC EORP EUROASPIRE V survey. Consecutive patients (aged 18-80 years), hospitalized for a first or recurrent coronary event were included in this study. Data at hospital discharge and at follow-up (6 to 24 months after hospitalisation) were collected.

RESULTS

Data were available for 8261 patients of which 25.8% women. Overall, women reported a worse EQ-5D-5L index score (0.73 vs. 0.81; P < 0.001), EQ-VAS (63.1 vs. 66.0; P = 0.001), global HeartQoL (1.94 vs. 2.26; P < 0.001), physical HeartQoL (1.96 vs. 2.30; P < 0.001), emotional HeartQoL (1.88 vs. 2.18; P < 0.001), HADS-A (6.69 vs. 4.99; P < 0.001), and HADS-D (5.73 vs. 4.62; P < 0.001) compared to men. Also, women were more likely to have comorbidities compared to men (1 comorbidity: 38.7% vs. 35.0%, 2 comorbidities: 9.7% vs. 7.5%; P < 0.001). There is indication that heart failure (EQ-VAS) and diabetes (global HeartQoL, emotional HeartQoL, physical HeartQoL, and HADS-D) interacted with gender and modulate the relationship with HRQoL, in disfavour of women.

CONCLUSION

Substantial gender-based health inequalities in terms of HRQoL and psychological distress were found, in disfavour of women. Women had worse HRQoL and psychological distress outcomes when having comorbidities. To a limited extent, comorbidity and women had a negative/synergistic effect on HRQoL. Special attention should be given to this population groups within daily clinical practice.

A Cross-Sectional Study: Determining Factors of Functional Independence and Quality of Life of Patients One Month after Having Suffered a Stroke

(1) Background: loss of quality of life (QoL) and functional independence are two of the most common consequences of suffering a stroke. The main objective of this research is to study which factors are the greatest determinants of functional capacity and QoL a month after suffering a stroke so that they can be considered in early interventions. (2) Methods: a cross-sectional study was conducted which sample consisted of 81 people who had previously suffered a stroke. The study population was recruited at the time of discharge from the Neurology Service and Stroke Unit of the hospitals of Burgos and Córdoba, Spain, through a consecutive sampling. Data were collected one month after participants experienced a stroke, and the main study variables were quality of life, measured with the Stroke-Specific Quality of Life Measure (NEWSQOL), and functional independence, measured with the Functional Independence Measure-Functional Assessment Measure (FIM-FAM). (3) Results: the factors associated with a worse QoL and functional capacity one month after having suffered a stroke were living in a different dwelling than the usual flat or house (p < 0.05), a worse cognitive capacity (p < 0.001) and a worse functional capacity of the affected upper limb (p < 0.001). A higher age was related to a worse functional capacity one month after suffering a stroke (p = 0.048). (4) Conclusions: the type of dwelling, age, cognitive ability and functional capacity of the affected upper limb are determining aspects in functional independence and QoL during the first weeks after a stroke.

Association of sex and age with in-hospital mortality and complications of patients with intracerebral hemorrhage: A study from the Chinese Stroke Center Alliance

BACKGROUND AND PURPOSE

The impact of sex and age on prognosis in patients with intracerebral hemorrhage (ICH) in the Chinese population remains unclear. Our study aimed to investigate the relationship between sex and age of Chinese ICH patients and adverse prognosis.

METHODS

We used the Chinese Stroke Center Alliance database with in-hospital mortality as the primary outcome and hospital complications as the secondary outcome. Patients were divided into four groups by sex and age. Logistic regression analyses were performed to assess the association between sex and age and the prognosis of ICH patients.

RESULTS

We enrolled 60,911 ICH patients, including 22,284 young and middle-aged males, 15,651 older males, 11,948 young and middle-aged females, and 11,028 older females. After adjusting for variables, older male patients had a higher mortality rate (OR = 1.21, 95% CI 1.01-1.45), combined with more frequent hematoma expansion (OR = 1.14, 95% CI 1.03-1.26), pneumonia (OR = 1.91, 95% CI 1.81-2.03), and hydrocephalus (OR = 1.28, 95% CI 1.04-1.59). Young and middle-aged female patients had a lower mortality rate (OR = 0.74, 95% CI 0.58-0.95) and less frequent combined pneumonia (OR = 0.81, 95% CI 0.75-0.87). In-hospital mortality was not significantly different in older females compared with young and middle-aged males, but the odds of deep vein thrombosis, swallowing disorders, urinary tract infections, and gastrointestinal bleeding were significantly higher.

CONCLUSION

Among young and middle-aged patients, females are related to a lower in-hospital mortality rate from ICH. Older patients are at an increased risk of ICH complications, with higher in-hospital mortality in older men.

Under contract and in good health: a multigroup cross-lagged panel model of time use and health-related quality of life in working-age men and women

Background

Self-reported time-use in relation to health-related quality of life (HRQoL) has been widely studied, yet less is known about the directionality of the association and how it compares across genders when controlling for sociodemographic confounders.

Methods

This study focused on the working population of the most recent waves (2013–2018) of the Core-Study of the German Socio-Economic Panel (N = 30,518, 46.70% female, M = 39.24 years). It examined the relationship between three time-use categories (contracted, committed, & leisure time) and HRQoL (self-rated health & life satisfaction) in men and women via multigroup fixed effects cross-lagged panel models. The models controlled for sociodemographic background (age, household income, number of children living in household, employment status, education, & marital status), which was associated with time-use and psychosocial health in previous research.

Results

Contracted time showed consistent positive relationships with HRQoL across genders while associations with the other types of time use differed significantly between men and women and across indicators of HRQoL.

Conclusions

The way we spend our time directly predicts our health perceptions, but in the same vein our health also predicts how we can spend our time. Contracted time in particular was associated with positive HRQoL, across genders, and beyond sociodemographic predictors, highlighting the important role of employment in health, for men and women alike. The impact of commitments beyond contracted time-use—like household chores and childcare—however, continues to affect mainly women, which ultimately reflects in poorer health outcomes.

Higher comorbidity burden is associated with lower self-reported quality of life after stroke

Introduction

This study assesses the association of comorbidity burden and polypharmacy with self-reported quality of life after stroke.

Patients and methods

We performed a post-hoc analysis of a prospective, single-center, observational study of outcome evaluation by patient-reported outcome measures in stroke clinical practice. Consecutive patients with acute ischemic stroke (AIS) were enrolled and self-reported health–related quality of life (HrQoL) was assessed 90 days after acute stroke using the Patient-reported Outcomes Measurement Information System 10-Question Short-Form (PROMIS-10). Comorbidities at baseline were assessed by the Charlson Comorbidity Index (CCI). Polypharmacy was defined as medication intake of ≥5 at baseline. We used linear regression analysis to study the association of CCI, polypharmacy and other clinical covariates with HrQoL after stroke.

Results

Of 781 patients (median age 76 years, 48.4% female) enrolled, 30.2% had a CCI Score ≥2, and 31.5% presented with polypharmacy. At follow up, 71 (9.1%) had died. In 409 (52.4%) reached for outcome evaluation, Global Physical Health T-Score was 43.8 ± 10 and Global Mental Health T-Score was 43.5 ± 8.76, indicating lower HrQoL than the average population. A CCI Score ≥2, higher NIHSS Score, female sex, dependency on others for dressing, toileting and mobility before index stroke, atrial fibrillation and hypertension were independent predictors of worse physical and mental health outcomes, while polypharmacy was not.

Conclusion

In patients with AIS, high comorbidity burden and polypharmacy are frequent. Comorbidity burden at admission is independently associated with worse self-reported physical and mental health three months after stroke.

Factors Contributing to Sex Differences in Health-Related Quality of Life After Ischemic Stroke: BASIC (Brain Attack Surveillance in Corpus Christi) Project

Background

Women have been reported to have worse health‐related quality of life (HRQoL) following stroke than men, but uncertainty exists over the reasons for the sex difference.

Methods and Results

We included all ischemic strokes registered with the BASIC (Brain Attack Surveillance in Corpus Christi) project (May 2010–December 2016), a population‐based stroke study, who completed a 90‐day outcome interview. Information on baseline characteristics was obtained from medical records and in‐person interviews. HRQoL was measured by the 12‐item short‐form Stroke Specific Quality of Life Scale. Multivariable Tobit regression was used to estimate the mean difference in overall HRQoL scores (range, 1–5; higher indicating better HRQoL) between sexes and to identify contributing factors to the differences. We included 1061 cases with complete data on HRQoL and covariates (median age, 67 years; 51% women). In unadjusted analyses, women had poorer overall HRQoL than men (mean difference, −0.26 [95% CI, −0.40 to −0.13]). Contributors to this difference included sociodemographic/prestroke factors (eg, age, race and ethnicity, prestroke function), risk factors/comorbidities (eg, history of stroke, Alzheimer disease/dementia), and initial stroke severity. Sociodemographic/prestroke factors explained 62% of the sex difference (mean difference, −0.08 [95% CI, −0.21 to 0.04]). In a fully adjusted model that included adjustment for all confounding factors, the sex difference was eliminated and became nonsignificant (mean difference, −0.03 [95% CI, −0.16 to 0.09]).

Conclusions

Poorer HRQoL in women compared with men was observed and explained by the combination of sociodemographic and prestroke factors, including physical function before stroke and stroke severity. The findings suggest potential subgroups of women who might benefit from more targeted interventions before and after stroke to improve HRQoL.

The effects of racism and resilience on Black stroke- survivor quality of life: Study protocol and rationale for a mixed-methods approach

Introduction

Stroke, a life-threatening stressor, often negatively impacts stroke-survivor (SS) quality of life (QoL). Annual age-adjusted incidence and death rates for stroke are significantly higher among Black Americans than among White Americans. Racism, a significant stressor, occurs at structural, cultural, and interpersonal levels and contributes to health disparities for Black SS. Resilience, a dynamic process of positive adaptation to significant stress, is impacted by factors or resources both internal and external to the individual. This study aims to examine the effects of experiences of racism and resilience on Black SS QoL during early stroke recovery. This article presents the study protocol.

Methods and analyses

This will be a prospective observational mixed-methods study. Black community-dwelling adults who are within 4 weeks of a stroke will be eligible for inclusion. Baseline measures will include the exposure variables of experiences of racism and resilience. Covariates measured at baseline include sociodemographic variables (age, sex, marital status, education, income, health insurance, employment status, number of people in household, residential address), clinical variables (date and type of stroke, inferred Modified Rankin Scale, anxiety and depression screening), and psychosocial variables (COVID-19 stress, perceived stress, mindfulness). The outcome variable (QoL) will be assessed 6-months post-stroke. Multiple-level linear regression models will be used to test the direct effects of experiences of racism, and the direct and indirect effects of resilience, on QoL. Qualitative data will be collected via focus groups and analyzed for themes of racism, resilience, and QoL.

Discussion

Racism can compound the stress exerted by stroke on Black SS. This study will occur during the COVID-19 pandemic and in the aftermath of calls for social justice for Black Americans. Experiences of racism will be measured with instruments for both “everyday” discrimination and vigilance. Sociodemographic variables will be operationalized to assess specific social determinants of health that intersect with structural racism. Because of the long-standing history of racism in the United States of America (USA), cultural influences and access to resources are central to the consideration of individual-level resilience in Black SS. Study results may inform the development of interventions to support Black SS QoL through enhanced resilience.

Sex Differences in Endovascular Therapy for Ischemic Stroke: Results From the Get With The Guidelines-Stroke Registry

BACKGROUND

In 2015, endovascular therapy (EVT) for large vessel occlusions became standard of care for acute ischemic stroke. Lower utilization of IV alteplase has been reported in women, but whether sex differences in EVT use in the United States exists has not been established.

METHODS

We identified all acute ischemic stroke discharges from Get With The Guidelines-Stroke hospitals between 2012 and 2019 who were potentially eligible for EVT, based on National Institutes of Health Stroke Scale score ≥6 and arrival <6 hours, according to 2018 American Heart Association/ASA guidelines. Multivariable regression analyses were used to determine the association between sex and EVT utilization, and outcomes (including mortality, discharge home, functional status) after EVT. Separate analyses were conducted for the 2 time periods: 2012 to 2014, and 2015 to 2019.

RESULTS

Of 302 965 patients potentially eligible for EVT, 42 422 (14%) received EVT. Before 2015, EVT treatment rates were 5.3% in women and 6.6% in men. From 2015 to 2019, treatment rates increased in both sexes to 16.7% in women and 18.5% in men. The adjusted odds ratio for EVT in women compared with men was 0.93 (95% CI, 0.87-0.99) before 2015, and 0.98 (95% CI, 0.96-1.01) after 2015. There were no significant sex differences in outcomes except that after 2015, women were less able to ambulate at discharge (adjusted odds ratio, 0.95 [95% CI, 0.95-0.99]) and had lower in-hospital mortality (adjusted odds ratio, 0.93 [95% CI, 0.88-0.99]).

CONCLUSIONS

EVT utilization has increased dramatically in both women and men since EVT approval in 2015. Following statistical adjustment, women were less likely to receive EVT initially, but after 2015, women were as likely as men to receive EVT. After EVT, women were more likely to be disabled at discharge but less likely to experience in-hospital death compared with men.

Health State Utility Values in People With Stroke: A Systematic Review and Meta-Analysis

Background Health state utility values are commonly used to provide summary measures of health-related quality of life in studies of stroke. Contemporaneous summaries are needed as a benchmark to contextualize future observational studies and inform the effectiveness of interventions aimed at improving post-stroke quality of life. Methods and Results We conducted a systematic search of the literature using Medline, EMBASE, and Web of Science from January 1995 until October 2020 using search terms for stroke, health-related quality of life, and indirect health utility metrics. We calculated pooled estimates of health utility values for EQ-5D-3L, EQ-5D-5L, AQoL, HUI2, HUI3, 15D, and SF-6D using random effects models. For the EQ-5D-3L we conducted stratified meta-analyses and meta-regression by key subgroups. We screened 14 251 abstracts and 111 studies met our inclusion criteria (sample size range 11 to 12 447). EQ-5D-3L was reported in 78% of studies (study n=87; patient n=56 976). The pooled estimate for EQ-5D-3L at ≥3 months following stroke was 0.65 (95% CI, 0.63-0.67), which was ≈20% below population norms. There was high heterogeneity (I2>90%) between studies, and estimates differed by study size, case definition of stroke, and country of study. Women, older individuals, those with hemorrhagic stroke, and patients prior to discharge had lower pooled EQ-5D-3L estimates. Conclusions Pooled estimates of health utility for stroke survivors were substantially below population averages. We provide reference values for health utility in stroke to support future clinical and economic studies and identify subgroups with lower healthy utility.

Toward a Better Understanding of Sex- and Gender-Related Differences in Endovascular Stroke Treatment: A Scientific Statement From the American Heart Association/American Stroke Association

There are many unknowns when it comes to the role of sex in the pathophysiology and management of acute ischemic stroke. This is particularly true for endovascular treatment (EVT). It has only recently been established as standard of care; therefore, data are even more scarce and conflicting compared with other areas of acute stroke. Assessing the role of sex and gender as isolated variables is challenging because they are closely intertwined with each other, as well as with patients' cultural, ethnic, and social backgrounds. Nevertheless, a better understanding of sex- and gender-related differences in EVT is important to develop strategies that can ultimately improve individualized outcome for both men and women. Disregarding patient sex and gender and pursuing a one-size-fits-all strategy may lead to suboptimal or even harmful treatment practices. This scientific statement is meant to outline knowledge gaps and unmet needs for future research on the role of sex and gender in EVT for acute ischemic stroke. It also provides a pragmatic road map for researchers who aim to investigate sex- and gender-related differences in EVT and for clinicians who wish to improve clinical care of their patients undergoing EVT by accounting for sex- and gender-specific factors. Although most EVT studies, including those that form the basis of this scientific statement, report patient sex rather than gender, open questions on gender-specific EVT differences are also discussed.

Sex differences in global disability-adjusted life years due to ischemic stroke: findings from global burden of diseases study 2019

To investigate the sex differences in disability-adjusted life years (DALYs) due to ischemic stroke (IS) by year, location and age. We extracted sex-specific data on DALYs number, age-standardized DALYs rate (ASDR) and all-age DALYs rate of IS by year, location and age from the Global Burden of Diseases study 2019. The estimated annual percentage changes (EAPC) were calculated to evaluate the temporal trend of ASDR. For both sexes, although the ASDR of IS slightly decreased from 1990 to 2019, there has been an 60.3% increase in DALYs number worldwide. Sex difference in DALYs number (men minus women) decreased from − 2.83 million in 1990 to 0.14 million in 2019, while the men to women’s ASDR ratio slightly increased from 1.10 in 1990 to 1.21 in 2019. The sex differences in IS DALYs showed remarkable regional variation. The largest sex differences in DALYs number and ASDR were in China and Vietnam. Middle-aged men had a higher IS DALYs than their age-matched counterparts. High systolic blood pressure accounted for the highest DALYs number in 2019, but the top three attributable risk factors that had the greatest sex differences were tobacco, dietary risk, and alcohol use. Sex differences in IS DALYs varied by year, location and age, mostly attributed to the disproportion of cardiovascular risk factors between sexes. Considering the population growth and aging, it is necessary to monitor the sex difference in IS DALYs in different populations and thus provide evidence for local administration to improve current preventive and management strategies of IS.

Sex Differences in the Long-Term Consequences of Stroke

Stroke is the fifth leading cause of death and as healthcare intervention improves, the number of stroke survivors has also increased. Furthermore, there exists a subgroup of younger adults, who suffer stroke and survive. Given the overall improved survival rate, bettering our understanding of long-term stroke outcomes is critical. In this review we will explore the causes and challenges of known long-term consequences of stroke and if present, their corresponding sex differences in both old and young survivors. We have separated these long-term post-stroke consequences into three categories: mobility and muscle weakness, memory and cognitive deficits, and mental health and mood. Lastly, we discuss the potential of common preclinical stroke models to contribute to our understanding of long-term outcomes following stroke.

Cardiovascular Risk Factor Profiles, Emergency Department Visits, and Hospitalizations for Women and Men with a History of Stroke or Transient Ischemic Attack: A Cross-Sectional Study

Background: The relationship between cardiovascular disease risk factors (CVD-RFs) and health care utilization may differ by sex. We determined whether having more CVD-RFs was associated with all-cause emergency department (ED) visits and all-cause hospitalizations for women and men with prior stroke/transient ischemic attack (TIA). Materials and Methods: In this cross-sectional study, we used nationally representative Medical Expenditure Panel Survey (2012-2015) data for persons aged ≥18 years with a prior stroke/TIA. CVD-RF summary scores include six self-reported factors (hypertension, diabetes, high cholesterol, physical inactivity, smoking, and obesity). Sex-specific covariate-adjusted logistic regression models assessed associations between CVD-RF scores and having one or more all-cause ED visits and one or more all-cause hospitalizations. Results: The weighted sample represents 9.1 million individuals (mean age 66.6 years; 54.3% women). Prevalence of low (0-1 risk factors), intermediate (2-3), and high (4-6) CVD-RF scores was 19.4%, 60.5%, and 20.1% for women and 14.6%, 60.2%, and 25.2% for men, respectively. Women having intermediate and high scores had a 1.58-fold (95% confidence interval [CI], 1.14-2.18) and 2.21-fold (95% CI, 1.50-3.25) increased odds of ED visits compared with women with low scores. Women with high CVD-RF scores had a 2.18-fold (95% CI, 1.42-3.34) increased odds of hospitalizations, but there was no association for women with intermediate CVD-RF profiles. There was no association between CVD-RF scores and either outcome for men. Conclusions: Women, but not men, with high and intermediate CVD-RF profiles had increased odds of all-cause ED visits; women with high CVD-RF profiles had increased odds of all-cause hospitalizations. The burden of CVD-RFs may be a sex-specific predictor of higher health care utilization in women with a history of stroke/TIA.

Predicting Individual Treatment Response to rTMS for Motor Recovery After Stroke: A Review and the CanStim Perspective

Background

Rehabilitation is critical for reducing stroke-related disability and improving quality-of-life post-stroke. Repetitive transcranial magnetic stimulation (rTMS), a non-invasive neuromodulation technique used as stand-alone or adjunct treatment to physiotherapy, may be of benefit for motor recovery in subgroups of stroke patients. The Canadian Platform for Trials in Non-Invasive Brain Stimulation (CanStim) seeks to advance the use of these techniques to improve post-stroke recovery through clinical trials and pre-clinical studies using standardized research protocols. Here, we review existing clinical trials for demographic, clinical, and neurobiological factors which may predict treatment response to identify knowledge gaps which need to be addressed before implementing these parameters for patient stratification in clinical trial protocols.

Objective

To provide a review of clinical rTMS trials of stroke recovery identifying factors associated with rTMS response in stroke patients with motor deficits and develop research perspectives for pre-clinical and clinical studies.

Methods

A literature search was performed in PubMed, using the Boolean search terms stroke AND repetitive transcranial magnetic stimulation OR rTMS AND motor for studies investigating the use of rTMS for motor recovery in stroke patients at any recovery phase. A total of 1,676 articles were screened by two blinded raters, with 26 papers identified for inclusion in this review.

Results

Multiple possible factors associated with rTMS response were identified, including stroke location, cortical thickness, brain-derived neurotrophic factor (BDNF) genotype, initial stroke severity, and several imaging and clinical factors associated with a relatively preserved functional motor network of the ipsilesional hemisphere. Age, sex, and time post-stroke were generally not related to rTMS response. Factors associated with greater response were identified in studies of both excitatory ipsilesional and inhibitory contralesional rTMS. Heterogeneous study designs and contradictory data exemplify the need for greater protocol standardization and high-quality controlled trials.

Conclusion

Clinical, brain structural and neurobiological factors have been identified as potential predictors for rTMS response in stroke patients with motor impairment. These factors can inform the design of future clinical trials, before being considered for optimization of individual rehabilitation therapy for stroke patients. Pre-clinical models for stroke recovery, specifically developed in a clinical context, may accelerate this process.

Sex Equitable Prehospital Stroke Triage Using Symptom Severity and Teleconsultation

Objectives: We aimed to determine whether there are sex differences in prehospital accuracy of the Stockholm Stroke Triage System (SSTS) to predict large artery occlusion (LAO) stroke, and endovascular thrombectomy (EVT), and whether clinical characteristics differ between men and women undergoing “code stroke” ambulance transport.

Materials and Methods: This prospective observational study collected data between October 2017 and October 2018. We included 2,905 patients, transported as “code stroke,” by nurse-staffed ground ambulance, to a Stockholm Region hospital. Exclusion criteria were private or helicopter transport, onset outside Stockholm, and in-hospital stroke. We compared overall accuracy, sensitivity, specificity, positive and negative predictive values, and clinical characteristics between sexes.

Results: No significant sex differences in SSTS predictive performance for LAO or EVT were found, overall accuracy for LAO 87.3% in women vs. 86.7% in men. Women were median 4 years older and more frequently had stroke mimics (46.2 vs. 41.8%). Women more commonly had decreased level of consciousness (14.0 vs. 10.2%) and moderate-to-severe motor symptoms (by 2.7–3.8 percentage points), and less commonly limb ataxia (7.2 vs. 9.7%).

Conclusions: The SSTS had equal predictive performance for LAO and EVT among men and women, despite minor sex differences in the clinical characteristics in patients undergoing ambulance transport for suspected stroke.

Women With Cerebral Infarction Feature Worse Clinical Profiles at Admission but Comparable Success to Men During Long-Term Inpatient Neurorehabilitation

Objective: Little is known about possible sex and gender differences in post-stroke neurorehabilitation outcomes. We aimed to analyze if functional performance, prevalence and impact of comorbidities at admission, and success of inpatient stroke-neurorehabilitation differ between men and women.

Methods: Retrospective cohort analysis of 1,437 men and 907 women with prior cerebral infarction treated at a neurorehabilitation clinic between 2012 and 2017; multiple linear regression was used to examine the influence of sex/gender as well as multiple confounders on health and functional outcomes. The main outcome measures were Barthel index (BI) at admission and its change during 4 weeks inpatient neurorehabilitation.

Results: Men had been diagnosed with osteoporosis less frequently than women but more often with type 2 diabetes mellitus, coronary artery or chronic kidney disease (p ≤ 0.01). Although twice as many women presented with pre-stroke depression compared to men, the risk of post-stroke depression detected during rehabilitation was comparable. Men were more likely to have less than 30 days between diagnosis and neurorehabilitation start than women (p < 0.03). At admission, women exhibited less autonomy, a lower BI, a higher pain score and worse 2-min walk test (2′WT) compared to men (p < 0.001). Among males osteoporosis and peripheral artery disease independently predicted BI at admission, in women it was pre-stroke depression, dementia, and arterial fibrillation. During neurorehabilitation, both sexes improved regarding BI, pain and walk tests (p < 0.001). Despite comparable rehabilitation effectiveness, women still had worse functional outcomes than males at discharge. Time after stroke to start of neurorehabilitation and length of the stay but, most strongly, the simple 2′WT at admission, and in women, pain intensity independently predicted post-stroke functional status and recovery.

Conclusion: Women presented with worse functional status at admission to neurorehabilitation. Although men and women showed similar rehabilitation effectiveness, women still displayed worse clinical outcome measures and higher levels of pain at discharge. Early access and gender-sensitive, personalized post-stroke care with more focus on different comorbidities and psychosocial factors like pain levels and management, could further improve neurorehabilitation outcomes.

Twenty-Year Change in Severity and Outcome of Ischemic and Hemorrhagic Strokes

Question

Did the initial neurological severity and functional outcomes of patients with stroke change throughout a 20-year period?

Findings

In this hospital-based, multicenter, prospective registry involving 183 080 patients with acute stroke, initial neurological severity showed a decrease over time in all stroke types. Functional outcome at hospital discharge improved in patients with ischemic stroke but no longer showed improvement after adjustment by reperfusion therapy and others; it did not clearly improve in patients with hemorrhagic stroke.

Meaning

Twenty-year changes in functional outcomes after ischemic and hemorrhagic strokes showed different trends presumably partly owing to differences in the development of acute therapeutic strategies.

Importance

Whether recent changes in demographic characteristics and therapeutic technologies have altered stroke outcomes remains unknown.

Objective

To determine secular changes in initial neurological severity and short-term functional outcomes of patients with acute stroke by sex using a large population.

Design, Setting, and Participants

This nationwide, hospital-based, multicenter, prospective registry cohort study used the Japan Stroke Data Bank and included patients who developed acute stroke from January 2000 through December 2019. Patients with stroke, including ischemic and hemorrhagic strokes, who registered within 7 days after symptom onset were studied. Modified Rankin Scale scores were assessed at hospital discharge for all patients.

Exposure

Time.

Main Outcomes and Measures

Initial severity was assessed by the National Institutes of Health Stroke Scale for ischemic stroke and intracerebral hemorrhage and by the World Federation of Neurological Surgeons grading for subarachnoid hemorrhage. Outcomes were judged as favorable if the modified Rankin Scale score was 0 to 2 and unfavorable if 5 to 6.

Results

Of 183 080 patients, 135 266 (53 800 women [39.8%]; median [IQR] age, 74 [66-82] years) developed ischemic stroke, 36 014 (15 365 women [42.7%]; median [IQR] age, 70 [59-79] years) developed intracerebral hemorrhage, and 11 800 (7924 women [67.2%]; median [IQR] age, 64 [53-75] years) developed subarachnoid hemorrhage. In all 3 stroke types, median ages at onset increased, and the National Institutes of Health Stroke Scale and World Federation of Neurological Surgeons scores decreased throughout the 20-year period on multivariable analysis. In ischemic stroke, the proportion of favorable outcomes showed an increase over time after age adjustment (odds ratio [OR], 1.020; 95% CI, 1.015-1.024 for women vs OR, 1.015; 95% CI, 1.011-1.018 for men) but then stagnated, or even decreased in men, on multivariate adjustment including reperfusion therapy (OR, 0.997; 95% CI, 0.991-1.003 for women vs OR, 0.990; 95% CI, 0.985-0.994 for men). Unfavorable outcomes and in-hospital deaths decreased in both sexes. In intracerebral hemorrhage, favorable outcomes decreased in both sexes, and unfavorable outcomes and deaths decreased only in women. In subarachnoid hemorrhage, the proportion of favorable outcomes was unchanged, and that of unfavorable outcomes and deaths decreased in both sexes.

Conclusions and Relevance

In this study, functional outcomes improved in patients with ischemic stroke during the past 20 years in both sexes presumably partly owing to the development of acute reperfusion therapy. The outcomes of patients with hemorrhagic stroke did not clearly improve in the same period.

Long-Term Trends in Stroke Management and Burden Among Low-Income Women in a Rural Area From China (1992-2019): A Prospective Population-Based Study

Although an increasing number of studies are considering sex-related differences in stroke burden, the trends in stroke burden and management among women in China, especially among low-income women, remain unclear. This study evaluated the long-term trends in stroke management and burden among low-income Chinese women during the period between 1992 and 2019. Stroke burden was assessed using the age-adjusted incidence of first-ever stroke, whereas stroke management was assessed using the rates of neuroimaging diagnoses, hospitalizations, case fatalities, and stroke recurrence. Stroke burden and management were analyzed during four study periods: 1992–1998, 1999–2004, 2005–2012, and 2013–2019. During the 193,385 person-years of surveillance in this study, 597 female stroke patients were identified. The stroke incidences per 100,000 person-years were 88.1 cases during 1992–1998, 145.4 cases during 1999–2004, 264.3 cases during 2005–2012, and 309.8 cases during 2013–2019 (P < 0.001). Between 1992 and 2019, the incidence of stroke significantly increased (6.4% annually) as did the incidence of ischemic stroke (7.8% annually; both, P < 0.001). The rates of neuroimaging diagnoses and hospitalizations significantly increased during the four periods, while the case fatality rates and 1-year recurrence rates decreased significantly for both overall strokes and ischemic strokes, especially among patients ≥45 years old (all, P < 0.001). Among low-income women in China, stroke management is gradually improving, despite the increasing stroke burden. Thus, improved healthcare coverage is needed to further reduce the stroke burden among low-income Chinese women.

Determinants of Physical Activity at 90 Days After Acute Stroke or Transient Ischemic Attack in Patients With Home Discharge: A Pilot Study

The aim was to identify the barriers to achieving premorbid physical activity in patients with home discharge after acute minor stroke or transient ischemic attack. Fifty-six patients (median age, 72 years) were analyzed. We assessed total physical activity in the premorbid condition and at 90 days after onset using the International Physical Activity Questionnaire. The patients were divided into two groups according to changes in total physical activity until 90 days after onset: decreased activity (n = 16) and nondecreased activity (n = 40) groups. Outcome measures were examined at discharge. The decreased activity group took significantly longer to perform the timed up and go test (median, 7.19 vs. 6.52 s) and contained more apathetic patients (44% vs. 15%). Apathy at discharge (relative risk 6.05, 95% confidence interval [1.33, 27.6]) was a significant determinant of decreased physical activity. Apathy is a barrier to the restoration of premorbid physical activity in stroke survivors.

Sex differences in vascular risk factors, in-hospital management, and outcomes of patients with acute ischemic stroke in China

BACKGROUND

Previous assessments of sex differences for patients with acute ischemic stroke were limited in a specific region or population, narrow scope, or small sample size.

METHODS

Patients with acute ischemic stroke hospitalized in the China Stroke Center Alliance hospitals were analyzed. Absolute standardized differences (ASDs) were used to assess sex differences in vascular risk factors, guideline-recommended in-hospital management measures and outcomes, including stroke severity (National Institutes of Health Stroke Scale≥16), death/discharge against medical advice, major adverse cardiovascular events, pneumonia, and disability (modified Rankin Scale≥3).

RESULTS

Of 838,229 patients analyzed, 524351 (62.6%) were men and 313,878 (37.4%) were women. Compared with men, women were older (68.6 vs. 64.7 years), had higher prevalence of hypertension (67.7% vs. 62.4%), diabetes (24.7% vs. 19.5%), and atrial fibrillation (7.1% vs. 4.3%), but lower prevalence of smoking (4.5% vs. 56.6%) and drinking (2.6% vs 35.8%) (ASDs >10%). No sex differences were seen in guideline-directed management measures, indicated by risk-adjusted individual measures and the all-or-null summary measure (34.5% vs 34.9%, ASD = 1.0%). Compared to men, women tended to have strokes that were more severe at presentation (6.5% vs. 4.5%, ASD = 8.8%) and more disabilities at discharge (34.9% vs 30.5%, ASD =9.4%). However, all sex-related differences in outcomes were attenuated to null after risk adjustments (ASDs<2%).

CONCLUSIONS

Compared to male patients, female patients had more vascular risk factors and received similar in-hospital care. They had strokes that were more severe at presentation and more disabilities at discharge, both of which may be explained by worse vascular risk profiles.

Health-related quality of life profiles and their dimension-specific associated factors among Malaysian stroke survivors: a cross sectional study

Background

Apart from maximizing functional abilities and independence after stroke, improving overall health-related quality of life (HRQoL) should also become part of the stroke treatment and rehabilitation process goals. This study aimed to assess the HRQoL profiles and explore the dimension-specific associated factors of HRQoL among stroke survivors.

Methods

This was a cross-sectional study of stroke survivors attending post-stroke care clinics in three public hospitals in the states of Pahang and Terengganu, Malaysia. The HRQoL was assessed by EuroQol-5 dimension-5 levels. Data on socio-demographic, clinical profiles, malnutrition risk, and physical activity level were collected through an interviewer-administered survey. Descriptive analyses for HRQoL profiles and multiple logistic regression analyses for its associated factors were performed. Crude and adjusted odds ratios were reported.

Results

A total of 366 stroke survivors were recruited with a mean age of 59 ± 11 years. The most -commonly reported health problems were mobility (85%), followed by usual activities (82%), pain/discomfort (63%), anxiety/depression (51%) and self-care (41%). The mean of the EQ visual analogue scale and the median of the EQ5D summary index was reported at 60.3 ± 14.2 and 0.67 ± 0.37, respectively. Malnutrition risk (mobility, usual activities, and self-care), wheelchair users (self-care and usual activities), speech impairment (usual activities and pain/discomfort), number of stroke episodes (self-care and pain/discomfort), body mass index, physical activity level and types of strokes (usual activities), age and use of a proxy (anxiety/depression), working and smoking status (mobility), were factors associated with either single or multiple dimensions of HRQoL.

Conclusion

Routine malnutrition screening, tailored program for speech therapy, prevention of recurrent stroke, and physical activity promotion should be addressed and further reinforced in current rehabilitation interventions to improve the HRQoL among stroke survivors in Malaysia.

Decoding the Transcriptional Response to Ischemic Stroke in Young and Aged Mouse Brain

Ischemic stroke is a well-recognized disease of aging, yet it is unclear how the age-dependent vulnerability occurs and what are the underlying mechanisms. To address these issues, we perform a comprehensive RNA-seq analysis of aging, ischemic stroke, and their interaction in 3- and 18-month-old mice. We assess differential gene expression across injury status and age, estimate cell type proportion changes, assay the results against a range of transcriptional signatures from the literature, and perform unsupervised co-expression analysis, identifying modules of genes with varying response to injury. We uncover downregulation of axonal and synaptic maintenance genetic program, and increased activation of type I interferon (IFN-I) signaling following stroke in aged mice. Together, these results paint a picture of ischemic stroke as a complex age-related disease and provide insights into interaction of aging and stroke on cellular and molecular level.

Effect of mood on long-term disability in younger stroke survivors: results from the Psychosocial Outcomes In StrokE (POISE) study

Background & Purpose: Anxiety and depression are common among stroke survivors, and their effect on long-term outcome remains unknown in those under 65 years of age. We investigated the association between early anxiety/depression after stroke and 12-month disability, and whether this is modified by sex.Methods: The Psychosocial Outcomes In StrokE (POISE) study was a prospective observational cohort study that recruited 441 younger (< 65 years) stroke survivors ≤28 days of acute stroke. Anxiety and depression were assessed using the Hospital Anxiety and Depression Scale, and disability using the World Health Organization Disability Assessment Scale version II (WHODAS-II). Associations between baseline anxiety/depression, and disability at 12-months was tested using analysis of covariance. Subgroup analysis was conducted using interaction term.Results: 92 (25%) had anxiety and 53 (14%) depression at baseline. Multivariable models showed significant association between baseline anxiety and 12-month disability (WHODAS-II score 15.24 vs. 11.49, p < .05). Those with anxiety had more impairment in 'cognition' (WHODAS-II score 18.26 vs. 8.71, p < .001), 'getting along' (WHODAS-II score 11.87 vs. 7.42, p < .05) and 'participation' (WHODAS-II score 22.37 vs. 15.92, p < .005) WHODAS-II. No significant relationship was found between baseline depression and long-term disability. There was no differential effect of anxiety by sex found in this study.Conclusions: Post-stroke anxiety has an adverse effect on disability at one year among young stroke survivors.

Implantable cardiac monitors to detect atrial fibrillation after cryptogenic stroke: a systematic review and economic evaluation

BACKGROUND

Cryptogenic stroke is a stroke for which no cause is identified after standard diagnostic tests. Long-term implantable cardiac monitors may be better at diagnosing atrial fibrillation and provide an opportunity to reduce the risk of stroke recurrence with anticoagulants.

OBJECTIVES

The objectives were to assess the diagnostic test accuracy, clinical effectiveness and cost-effectiveness of three implantable monitors [BioMonitor 2-AF™ (Biotronik SE & Co. KG, Berlin, Germany), Confirm Rx™ (Abbott Laboratories, Lake Bluff, IL, USA) and Reveal LINQ™ (Medtronic plc, Minneapolis, MN, USA)] in patients who have had a cryptogenic stroke and for whom no atrial fibrillation is detected after 24 hours of external electrocardiographic monitoring.

DATA SOURCES

MEDLINE, EMBASE, The Cochrane Library, Database of Abstracts of Reviews of Effects and Health Technology Assessment databases were searched from inception until September 2018.

REVIEW METHODS

A systematic review was undertaken. Two reviewers agreed on studies for inclusion and performed quality assessment using the Cochrane Risk of Bias 2.0 tool. Results were discussed narratively because there were insufficient data for synthesis. A two-stage de novo economic model was developed: (1) a short-term patient flow model to identify cryptogenic stroke patients who have had atrial fibrillation detected and been prescribed anticoagulation treatment (rather than remaining on antiplatelet treatment) and (2) a long-term Markov model that captured the lifetime costs and benefits of patients on either anticoagulation or antiplatelet treatment.

RESULTS

One randomised controlled trial, Cryptogenic Stroke and underlying Atrial Fibrillation (CRYSTAL-AF) (Sanna T, Diener HC, Passman RS, Di Lazzaro V, Bernstein RA, Morillo CA, et al. Cryptogenic stroke and underlying atrial fibrillation. N Engl J Med 2014;370:2478-86), was identified, and no diagnostic test accuracy study was identified. The CRYSTAL-AF trial compared the Reveal™ XT (a Reveal LINQ predecessor) (Medtronic plc) monitor with standard of care monitoring. Twenty-six single-arm observational studies for the Reveal devices were also identified. The only data for BioMonitor 2-AF or Confirm Rx were from mixed population studies supplied by the companies. Atrial fibrillation detection in the CRYSTAL-AF trial was higher with the Reveal XT than with standard monitoring at all time points. By 36 months, atrial fibrillation was detected in 19% of patients with an implantable cardiac monitor and in 2.3% of patients receiving conventional follow-up. The 26 observational studies demonstrated that, even in a cryptogenic stroke population, atrial fibrillation detection rates are highly variable and most cases are asymptomatic; therefore, they probably would not have been picked up without an implantable cardiac monitor. Device-related adverse events, such as pain and infection, were low in all studies. The de novo economic model produced incremental cost effectiveness ratios comparing implantable cardiac monitors with standard of care monitoring to detect atrial fibrillation in cryptogenic stroke patients based on data for the Reveal XT device, which can be related to Reveal LINQ. The BioMonitor 2-AF and Confirm RX were included in the analysis by making a strong assumption of equivalence with Reveal LINQ. The results indicate that implantable cardiac monitors could be considered cost-effective at a £20,000-30,000 threshold. When each device is compared incrementally, BioMonitor 2-AF dominates Reveal LINQ and Confirm RX.

LIMITATIONS

The cost-effectiveness analysis for implantable cardiac monitors is based on a strong assumption of clinical equivalence and should be interpreted with caution.

CONCLUSIONS

All three implantable cardiac monitors could be considered cost-effective at a £20,000-30,000 threshold, compared with standard of care monitoring, for cryptogenic stroke patients with no atrial fibrillation detected after 24 hours of external electrocardiographic monitoring; however, further clinical studies are required to confirm their efficacy in cryptogenic stroke patients.

Predicting Decreased Activities of Daily Living in Patients with Moyamoya Disease after Revascularization: Development and Assessment of a New Predictive Nomogram

The aim of this study was to develop and validate a nomogram model to predict the risk of decreased activities of daily living (ADLs) in patients with moyamoya disease (MMD) following revascularization. The nomogram model was constructed based on data from 292 patients with MMD that were treated at Qilu Hospital of Shandong University from January 2018 to June 2019. The prediction model was assessed using a dataset of 119 patients with MMD collected from July 2019 to June 2020. Patients were evaluated with a general information questionnaire and the Mini Mental Status Examination, Hospital Anxiety and Depression Scale, Social Support Rating Scale, and ADL Scale. Multivariable logistic regression analysis was applied to build a prediction model incorporating the features selected in the least absolute shrinkage and selection operator regression model. Discrimination, calibration, and clinical usefulness of the prediction model were assessed using receiver operating characteristic (ROC) curves, calibration plots, and decision curve analysis. Predictors contained in the nomogram included gender, age, monthly income, hypertension, and cognitive function and depression scores. The areas under the ROC curves of the training and testing datasets were 0.938 and 0.853, respectively. The prediction model displayed good calibration, and the decision curve analysis showed that it had a wide range of clinical applications. This novel predictive could be conveniently used to predict the risk of the decreased living activity ability in patients with MMD.

A prediction model of health-related quality of life in young adult patients with stroke

AIMS AND OBJECTIVES

This study aimed to establish and test a predictive model for explaining the health-related quality of life of young adult patients with stroke.

BACKGROUND

Individual characteristics, biological and physiological variables, social support, emotional and cognitive symptoms, physical function disability and general health perception may be interrelated and may directly or indirectly affect the health-related quality of life of young adult patients with stroke.

DESIGN

A cross-sectional study.

METHODS

237 young outpatients with stroke were recruited and surveyed. Data collection used a structured questionnaire from July-November 2018. The collected data were analysed using SPSS version 25.0^® and AMOS 23.0. This study is based on STROBE guidelines.

RESULTS

The hypothetical model's fit indices were adequate. Stroke severity, social support, fear of stroke recurrence, physical function disability and general health perceptions directly affected the health-related quality of life. Additionally, stroke severity, depression and fear of stroke recurrence also indirectly affected it. These variables explained 60.3% of the variance in this quality.

CONCLUSIONS

Variables such as severity of stroke, depression, fear of stroke recurrence, social support, physical function disability and general health perception were found to be related to the HRQoL of young adult patients with stroke.

RELEVANCE TO CLINICAL PRACTICE

A variety of physical, psychological, functional and social factors related to health-related quality of life should be systematically monitored. Furthermore, nurses need to develop and apply detailed nursing interventions that take into account all these variables.

Health-related quality of life, anxiety and depression up to 12 months post-stroke: Influence of sex, age, stroke severity and atrial fibrillation - A longitudinal subanalysis of the Find-AFRANDOMISED trial

BACKGROUND

Stroke can negatively impact the health-related quality of life (HRQoL). Anxiety or depression after stroke have been associated with poorer HRQoL, higher mortality and greater dependence in activities of daily living. We aimed to analyze HRQoL, anxiety and depressive symptoms in patients with and without atrial fibrillation (AF) up to 12 months post-stroke.

METHODS

Find-AF_RANDOMISED was a prospective, randomized multicenter study, which included 398 patients ≥60 years with acute cerebral ischemia. HRQoL data were collected using the 3-level EuroQol-5D (EQ-5D-3L) and Stroke Impact Scale (SIS-16). Anxiety and depressive symptoms were measured using the Hospital Anxiety and Depression Scale (HADS). The severity of stroke was measured using the modified Rankin Scale (mRS).

RESULTS

In this study (mean age 72.7 ± 7.5 years, 40.2% females), there was a significant improvement in HRQoL using EQ-5D-3L after 3 months (β = 0.37, p < .01), 6 months (β = 0.43, p < .01) and 12 months (β = 0.44, p < .01) post-stroke compared to baseline. HADS anxiety scores after 3 months (β = -0.22, p < .01) and 12 months (β = -0.28, p < .01) were significantly reduced. Older patients reported reduced HRQoL and more depressive symptoms. Females indicated lower HRQoL and more anxiety. mRS score at baseline was an independent predictor for HRQoL. There was a significant but small effect of AF on EQ-5D-3L and on HADS anxiety.

CONCLUSIONS

Patients showed significant improvement in HRQoL and reduced anxiety after 3 and 12 months after stroke. We could demonstrate that the severity of stroke as well as sex and age impact long-term post-stroke HRQoL.

Clinical impact of estradiol/testosterone ratio in patients with acute ischemic stroke

BACKGROUND

Sex hormones may be associated with a higher incidence of ischemic stroke or stroke-related events. In observational studies, lower testosterone concentrations are associated with infirmity, vascular disease, and adverse cardiovascular risk factors. Currently, female sexual hormones are considered neuroprotective agents. The purpose of this study was to assess the role of sex hormones and the ratio of estradiol/testosterone (E/T) in patients with acute ischemic stroke (AIS).

METHODS

Between January 2011 and December 2016, 146 male patients with AIS and 152 age- and sex-matched control subjects were included in this study. Sex hormones, including estradiol, progesterone, and testosterone, were evaluated in the AIS patient and control groups. We analyzed the clinical and physiological levels of sex hormones and hormone ratios in these patients.

RESULTS

The E/T ratio was significantly elevated among patients in the stroke group compared to those in the control group (P = 0.001). Categorization of data into tertiles revealed that patients with the highest E/T ratio were more likely to have AIS [odds ratio (OR) 3.084; 95% Confidence interval (CI): 1.616-5.886; P < 0.001) compared with those in the first tertile. The E/T ratio was also an independent unfavorable outcome predictor with an adjusted OR of 1.167 (95% CI: 1.053-1.294; P = 0.003).

CONCLUSIONS

These findings support the hypothesis that increased estradiol and reduced testosterone levels are associated with AIS in men.

Health-related quality of life after ischemic stroke: impact of sociodemographic and clinical factors

BACKGROUND AND AIMS

Ischemic stroke (IS) is one of the leading causes of death and long-term disability in Bulgaria. IS affects different aspects of the patient's life and results in loss of independence and poor health-related quality of life (HR-QoL). We aimed to analyze the impact of IS on HR-QoL and to identify possible associations with sociodemographic, clinical features, and vascular risk factors (RF).

METHODS

A prospective, hospital-based study was undertaken from 1 July 2019 to 31 June 2020, at a tertiary care referral center for neurological disorders in Bulgaria. A total of 150 patients with acute IS - 50 with thrombolytic and 100 with non-thrombolytic therapy - were included. Thorough clinical and sociodemographic data were collected. The NIHSS scale determined stroke severity, and HR-QoL was assessed with the Stroke Impact Scale Version 3.0 (SIS 3.0) during the first 3 months.

RESULTS

The overall HR-QoL improved during the observation period, but still, it remained significantly worse. The major predictors of a marked reduction in HR-QoL were age, female sex, lower education level, and actively working at stroke onset, high NIHSS score, anterior circulation stroke, and more extended hospital. Atrial fibrillation and heart failure were significantly associated with poor HR-QoL. The other investigated vascular risk factors were associated with different extends with poorer HR-QoL, except for dyslipidemia.

CONCLUSION

Stroke survivors have significantly reduced HR-QoL. Multiple interacting factors are associated with an unfavorable outcome after IS. Early detection of these factors would help to improve the care for IS patients, to reduce disabilities and improve HR-QoL.

Cerebrovascular disease in women

Cerebrovascular disease is a major cause of morbidity, mortality, and disability in women. The spectrum of disease differs between men and women, with women being particularly vulnerable to certain conditions, especially during specific periods of life such as pregnancy. There are several unique risk factors for cerebrovascular disease in women, and the influence of some traditional risk factors for stroke is stronger in women. Moreover, disparities persist in representation of women in clinical trials, acute intervention, and stroke outcomes. In this review, we aimed to explore the epidemiology, etiologies, and management of cerebrovascular disease in women, highlighting some of these differences and the growing need for sex-specific management guidelines and health policies.

Cross-cultural adaptation and validation of the Igbo language version of the stroke-specific quality of life scale 2.0

Introduction

availability of the Stroke-Specific Quality of Life scale 2.0 (SS-QoL(E)) in Yoruba and Hausa, two of the three major indigenous languages in Nigeria have the potential to promote its uptake among these population, however, its non-availability in the Igbo languages makes its use restrictive among the south-eastern Nigerians. This study was aimed at cross-culturally adapting and assessing validity and reliability of the Igbo version of the SS-QoL.

Methods

the SS-QoL(E) was cross-culturally adapted to Igbo following the American Association of Orthopaedic Surgeons’ guideline. This involved forward and back-translations, expert committee review, pretesting and cognitive debriefing interview to produce the final Igbo version, SS-QoL(I). The validity and reliability test involved 50 consenting Igbo stroke survivors. The construct validity was assessed by administering SS-QoL(E) and SS-QoL(I) on all 50 respondents, while SS-QoL(I) was re-administered at 7-day interval to assess test-retest reliability. Each scale was administered in random order. Data were analysed using Spearman’s correlation, Wilcoxon’s signed-rank test, Cronbach’s alpha, Intra-class Correlation Coefficient (ICC), independent t-test and one-way ANOVA at p<0.05.

Results

respondents’ domains scores on SS-QoL(E) and SS-QoL(I) did not differ significantly except in mobility and work (r=0.58 to 0.87; p=0.001). Cronbach’s alpha was 0.69 to 0.87 for domains scores. The ICC ranged from 0.48 to 0.84, while no significant differences was found across different age groups or gender for the domains or overall scores of SS-QoL(I).

Conclusion

the Igbo version of the SS-QoL has limited alterations from the original version and has moderate to excellent validity and reliability values.
