Healthy food diversity and the risk of major chronic diseases in the EPIC-Potsdam study.

Practicing a diverse diet may reduce chronic disease risk, but clear evidence is scarce and previous diet diversity measures rarely captured diet quality. We investigated the effect of the Healthy Food Diversity (HFD)-Index on incident type 2 diabetes (T2D), myocardial infarction (MI) and stroke among a middle-aged German population. The EPIC-Potsdam study recruited 27,548 participants from 1994 to 1998. Semiquantitative food frequency questionnaire was used to calculate the HFD-Index. Longitudinal associations of HFD-Index and verified incident diseases were investigated by multiple-adjusted Cox proportional hazards regression models. Among 26,591 participants (mean age 50.5years, 60% women), 1537, 376 and 412 developed T2D, MI and stroke, respectively, over an average follow-up of 10.6years. There was no association between HFD-Index and incident T2D or MI. Higher compared to lower HFD-Index was inversely associated with incident stroke in men [HR (95% CI): 0.80 (0.70, 0.92)], but positively associated with incident stroke in women [1.20 (1.01, 1.42)]. Although there was no clear association between HFD-Index and T2D or MI incidence, we found a beneficial association in men and a harmful association in women for incident stroke. We emphasised the need for further investigations on combining diet diversity and diet quality in relation to health outcomes.

Identifying predictors of stroke in young adults: a machine learning analysis of sex-specific risk factors

IntroductionStroke among Americans under age 49 is increasing. While the risk factors for stroke among older adults are well-established, evidence on stroke causes in young adults remains limited. This study used machine learning techniques to explore the predictors of stroke in young men and women.MethodsThe least absolute shrinkage and selection operator algorithm (LASSO) was applied to data from Wave V of the National Longitudinal Survey of Adolescent to Adult Health (N = 12,300)—nationally representative, longitudinal panel containing demographic, lifestyle, and clinical information for individuals aged 33–43—to identify the key factors associated with stroke in men and women. The resulting LASSO model was tested and validated on an independent sample and model performance was assessed using the area under the receiver operating characteristic curve (AUC) and calibration. For robustness, synthetic minority over sampling technique (SMOTE) was applied to address data imbalance and analyses were repeated on the balanced sample.ResultsApproximately 1.1% (N = 59) and 1.3% (N = 90) of the 5,318 and 6,970 men and women in the sample reported having a stroke. LASSO was used to predict stroke using demographic, lifestyle, and clinical predictors on both balanced and imbalanced data sets. LASSO performed slightly better on the balanced data set for women compared to the unbalanced set (Female AUC: 0.835 vs. 0.842), but performance for men was nearly identical (Male AUC: 0.820 vs. 0.822). Predictor identification was similar across both sets. For females, marijuana use, receipt of health services, education, self-rated health status, kidney disease, migraines, diabetes, depression, and PTSD were predictors. Among males, income, kidney disease, heart disease, diabetes, PTSD, and anxiety were risk factors.ConclusionsThis study showed similar clinical risk factors among men and women. However, variations in the behavioral and lifestyle determinants between sexes highlight the need for tailored interventions and public health strategies to address sex-specific stroke risk factors among young adults.

Sex Differences in Profile and In-Hospital Death for Acute Stroke in Chile: Data From a Nationwide Hospital Registry.

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. 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. 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.

Acute Care, Secondary Prevention, and Outcomes after Ischaemic and Haemorrhagic Stroke in Men and Women: A Data-Linkage Study.

There is evidence that sex differences exist in stroke presentation, risk factors, severity, treatment, and outcomes. To further understand this, we explored how sex differences influence acute stroke management, secondary prevention prescribing, and mortality outcomes in a well-characterised cohort of first-ever stroke patients in Scotland. This is a retrospective, population-based, data-linkage study of stroke admissions to acute care hospitals in Scotland between January 1, 2011, and December 31, 2018. Data sources included the Scottish Stroke Care Audit (SSCA), the Prescribing Information System (PIS), the Scottish Morbidity Record 01 (SMR01), and the National Records of Scotland (NRS) death records. Multivariable logistic regression was used to explore the association between patient sex, acute stroke care, and secondary prevention prescribing, while Cox proportional hazards models were used to explore the association between patient sex and all-cause mortality up to 1 year after index event. This study included 5,901 patients with a first-ever intracerebral haemorrhage (ICH) and 47,087 patients with a first-ever acute ischaemic stroke (AIS). After an ICH, women had significantly lower odds of receiving all components of the stroke care bundle (adjusted odds ratio [aOR], 0.78; 95% confidence interval [CI], 0.69-0.87) and were less likely to be prescribed antihypertensives within 90 days after discharge to the usual place of residence (aOR, 0.78; 95% CI, 0.63-0.97). There was no sex difference in stroke care bundle achievement for those admitted with AIS; however, women had significantly lower odds of receiving antihypertensives, lipid-lowering drugs, or oral anticoagulants after discharge. The risk of all-cause mortality was lower in women at 1 year after both ICH (adjusted hazard ratio [aHR], 0.90; 95% CI, 0.83-0.98) and AIS (aHR, 0.91; 95% CI, 0.87-0.95) after adjusting for potential confounders. The sex differences in stroke treatment and outcomes may be partly explained by the older age of women at the time of stroke, which influences stroke presentation, severity, and prognosis. However, following adjustment, women had a reduced risk of all-cause mortality after both ICH and AIS.

Sex differences in the association between plasma branched-chain amino acids and risk of ischemic stroke: A nested case-control study from China

ObjectivesThe aim of this study was to investigate the prospective associations between plasma branched-chain amino acids (BCAAs) and the risk of ischemic stroke in men and women. MethodsWe conducted a nested case-control study within a community-based cohort in China. The cohort consisted of 15,926 participants in 2013-2018. A total of 321 ischemic stroke cases were identified during the follow up and individually matched with 321 controls by date of birth (±1 year) and sex. Females accounted for 55.8% (n = 358, 179 cases vs 179 controls) of the study population. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to assess the association between plasma BCAAs and ischemic stroke risk by conditional logistic regression. ResultsElevated plasma isoleucine was associated with a higher risk of ischemic stroke in women. The OR for the highest compared to the lowest quartile was 2.22 (95% CI: 1.11-4.44, P trend = 0.005) after adjustment for body mass index, education attainment, smoking, hypertension, renal function, menopause and physical activity. A similar association was found for total BCAAs (adjusted OR = 2.03, 95% CI: 1.05-3.95, P trend = 0.04). In contrast, no significant association of plasma BCAAs with ischemic stroke risk was observed in men. ConclusionsPlasma isoleucine and total BCAAs were significantly associated with ischemic stroke risk in women, but not in men, highlighting sex differences in BCAAs metabolism and stroke pathogenesis.

The impact of residential environment on stroke onset and its spatial heterogeneity: A multiscale exploration in Shanghai

BackgroundStroke is a worldwide concern due to its high disability and mortality rates, especially in many countries entering ageing societies. This study aims to understand the spatial heterogeneity of stroke onset and residential environment influence scopes from multiscale. MethodsThe 2013 to 2022 spatiotemporal distribution pattern of stroke onset was obtained via out-patient data from a hospital in Shanghai. Then nine residential environmental factors were selected to estimate the association of stroke onset by multiscale geographically weighted regression (MGWR), in three scenarios. ResultsAccessibility to pubs/bars (PUB) and building density (BD) were the top two residential environmental factors both for the entire sample and by gender. Stress-related environmental factors have a greater impact on the onset of stroke in men but are limited in scope. The population of elderly people have relevance to environmental variables heterogeneity. The indicators relating to unhealthy food and alcohol suggest that habit-inducing environmental factors have a limited impact on stroke onset, but rather that pre-existing habits play a greater role. ConclusionsMGWR analyses individual components across multiple bandwidths, revealing geographical disparities in the impact of elements that would otherwise be undetected on a global scale. Environmental factors have a limited impact on the onset of stroke. When society is faced with both heavy ageing and fiscal constraints, some of the blue-green space budgets can be scaled back to invest in more secure facilities.

Ischemic Stroke in Men Aged 18–50 Years

Ischemic Stroke in Men Aged 18–50 Years

Proton Pump Inhibitor Use and the Risk of Cardiovascular Complications and Death in Older Adults with Diabetes: A Population-Based Cohort Study.

The unfavorable effect of proton pump inhibitors (PPIs) on cardiovascular (CV) outcomes and mortality was reported in the general population. We investigated the impact of PPIs on CV outcomes and total mortality in older people with diabetes mellitus (DM) for whom evidence is missing. Using administrative health databases of the Lombardy Region, we analyzed the risk of myocardial infarction (MI), ischemic stroke and total mortality in individuals with DM (≥65 years of age) exposed to PPIs in 2015 and followed up to 2021. The outcomes were analyzed using a multivariable-adjusted Cox proportional hazards model to compute hazard ratios (HRs) with 95% confidence intervals (CIs). HRs between PPI users and non-users were also estimated in selected subgroups. A sensitivity analysis was also performed in a 1:1 propensity score matching population. A total of 284,068 patients were included in the analysis (49.4% PPI users, 50.6% non-PPI users). A higher prevalence of comorbidities and medications was reported in PPI users as compared with non-users. During a median follow-up of 6.7 years, the use of PPIs was associated with a higher risk for ischemic stroke (HR 1.14, 95% CI 95% 1.08-1.20), MI (HR 1.36, 95% CI 1.31-1.41) and total mortality (HR 1.24, 95% CI 1.22-1.26). These risks were higher in PPI users regardless of the PPI type. Among sexes, previous CV diseases, and insulin subgroups, the use of PPIs was correlated with a statistically significant increased risk of ischemic stroke in men, in individuals without a history of CV disease, and in those who were not treated with insulin. A significantly higher risk of MI was associated with PPIs for all subgroups, as well as for total mortality, with the exception of patients with a previous history of CV diseases. The sensitivity analysis confirmed the results of the unmatched cohort. Our findings confirmed an increased risk of CV events and all-cause mortality in a large population of older adults with DM exposed to PPIs. This could have an important impact on public health and costs for National Health Service, therefore a regular assessment of PPI appropriateness is recommended, particularly in this population.

Ischemic stroke in men 18-50 years of age

To evaluate the main modifiable risk factors for ischemic stroke (IS) and features of the course in atherothrombotic, cardioembolic, and lacunar subtypes of IS in men aged 18-50 years. The study included 125 men (the mean age was 42.6±5.3 years) who were admitted to the Vascular department before the COVID-19 pandemic and survived for the first 30 days after IS. Information on patients' baseline characteristics, traditional vascular risk factors, and lifestyle risk factors was systematically collected. Neuroimaging, ultrasound and laboratory tests were performed. Atherothrombotic subtype was identified in 60 patients, lacunar subtype in 46 patients and cardioembolic subtype in 19 patients. In the group as a whole, major risk factors included arterial hypertension (83.2%), dyslipidemia (50.4%), smoking (67.2%), alcohol consumption (29.6%), obesity (16.8%), heart rhythm disorders (12%), and diabetes mellitus (8%). The study revealed the main risk factors, the frequency of which differed depending on the stroke subtype and the age of the patients.

Disease burden based on gender and age and risk factors for stroke in China, 2019.

Stroke has become the leading cause of death and disability among adults in China. This study aims to analyze the disease burden based on gender and age and the risk factors for stroke subtypes in China 2019, and to provide reference for targeted stroke prevention and control. Based on 2019 data of the Global Burden of Disease (GBD), the gender and age in patients with different stroke subtypes (ischemic stroke, intracranial hemorrhage, subarachnoid hemorrhage) in China 2019 was described by using disability-adjusted life years (DALY), and attributable burden of related risk factors was analyzed. In 2019, the burden of intracranial hemorrhage was the heaviest one in China, resulting in 22.210 6 million person years of DALY, following by ischemic stroke and subarachnoid hemorrhage, resulting in 21.393 9 and 2.344 7 million person years of DALY, respectively. Among them, except the 0-14 age group, the disease burden of different subtypes of stroke in men was higher than that in women. The disease burden of ischemic stroke was increased with age in both men and women, with the heaviest disease burden in ≥70 years group. The disease burden of intracranial hemorrhage and subarachnoid hemorrhage was the heaviest in males aged 50-69 years old, and in females aged ≥70 years and 50-69 years, respectively. Metabolic factors were the main risk factors in all ages of different stroke subtypes, and the most important risk factor was high systolic blood pressure. Other risk factors were different between men and women. Smoking, high body mass index, high low-density lipoprotein, and outdoor particulate matter pollution were the main risk factors for stroke in men, while high body mass index, outdoor particulate matter pollution, and high fasting blood glucose were the main risk factors of stroke in women. The main risk were different among different age groups. The burden and attributable risk factors for different stroke subtypes are discrepancy in different gender and age groups. Targeted interventions should be conducted in the future to reduce the burden of stroke.

Association of Resting Heart Rate with the Risk of Stroke in Men.

A resting heart rate may be correlated with an increased risk of stroke. Therefore, we explored the independent and joint influences of heart rate and body mass index on the incidence of stroke and its sub-types in a Chinese rural population. Cox proportional hazard models were adopted for measuring the influence exerted by heart rate on stroke in the Tongxiang China Kadoorie Biobank prospective cohort analyses, in which 23,132 men and 32,872 women were included. Incident stroke refers to '24-hour acute focal disorder, considered to result from ischemia or intracranial hemorrhage'. Over a 6.9 year mean follow up period, 986 men and 925 women developed stroke, representing an incidence of 6.35 and 4.00 per 1,000 person-years. In contrast to men with heart rate < 69 beats/minute, men at heart rate ≥ 90 beats/minute could more probably develop stroke and ischemic stroke with representing hazard ratio [95% confidence interval (CI)] 1.29 (1.05 - 1.58), and 1.35 (1.06 - 1.71). An adjusted hazard ratio of 1.37 (95% CI = 1.06 - 1.74) and 1.46 (95% CI = 1.08 - 1.96) were respectively identified for stroke and ischemic stroke in non-overweight/obese male patients with heart rate ≥ 90 beats/minute. Joint analyses also favored the results. Unfortunately, non-significant results were found in women. Higher resting heart rate acts as an independent predictor of any stroke and ischemic stroke risk in adult Chinese male but not in female. This relationship was particularly evident among nonoverweight/obese male participants.

Risk factors for ischemic stroke in men and women aged 45–74 years

Stroke is one of the leading causes of death and primary disability and contributes significantly to the global burden of disease. Identification of individuals at high risk of ischemic stroke (IS) is an important component of disease prevention. The differences between risk factors (RF) for stroke in men and women are not well understood.Objective: to determine the predictive value of RF for the development of IS in men and women aged 45–74 years.Material and methods. The study included 728 patients (380 men and 348 women) aged 45–74 years, including 392 patients (247 men and 145 women) with IS in the carotid artery basin (main group) and 336 patients (133 men and 203 women) with vascular cognitive impairment (comparison group). To build predictive models to assess the impact of RF on the development of IS in men and women, we used the logistic regression method with stepwise exclusion of variables according to the Wald algorithm.Results. The predictive regression model of IS in men includes atherosclerotic stenosis of the internal carotid arteries [odds ratio (OR) 3.571; 95% confidence interval (CI) 1.792–7.114], in a predictive regression model in women – diabetes mellitus type 2 (OR 5.074; 95% CI 1.768–14.561) and a history of IS (OR 6.857; 95% CI 1.825–25.762). Other risk factors for the development of IS (atrial fibrillation, history of transient ischemic attack, arterial hypertension stage) affected both men and women.Conclusion. Atherosclerotic stenosis of the internal carotid arteries was found to be a sex-specific prognostic factor for IS in men, and type 2 diabetes mellitus and a history of IS in women.

Trends in mortality from major causes and lifestyle factors by per capita prefectural income: Ecological panel data analysis from 1995 to 2016 in Japan

In Japan, trends in mortality and lifestyle have not been fully investigated according to subnational socioeconomic factors. Forty-seven prefectures (subnational units) were divided into quartiles by annual per capita prefectural income. Age-standardized mortality from all causes, cancer, heart disease, and stroke was averaged by quartile in 1995, 2000, 2005, 2010, and 2015. Data from the National Health and Nutrition Survey were obtained for periods 1 (1995–1997), 2 (1999–2001), 3 (2003–2005), 4 (2007–2009), 5 (2012), and 6 (2016). Body mass index (BMI), the intake of vegetables and salt, the number of steps, and the prevalence of current smoking and drinking for the 40–69-year age range were standardized by 10-year age groups in the 2010 Japanese population and were averaged by quartile. Differences in mortality and lifestyle by year and period, and quartile were tested using a two-way analysis of variance. Mortality decreased in both sexes and mortality in men from all causes, cancer, and stroke differed by quartile, with mortality highest in the first (lowest) quartile. BMI in men and smoking prevalence in women increased, whereas remaining lifestyle factors except for the prevalence of drinking decreased in women. BMI and the number of steps in both sexes and current smoking prevalence in women differed by quartile, with lower quartiles showing a higher BMI and fewer step counts. In conclusion, favorable trends and significant differences in mortality from all causes, cancer, and stroke in men and BMI in women were observed by per capita prefectural income level.

Association between extremely high-density lipoprotein cholesterol and adverse cardiovascular outcomes: a systematic review and meta-analysis.

The association between high-density lipoprotein cholesterol (HDL-C) and adverse cardiovascular outcomes is understudied. Based on cohort studies, the current study aimed to investigate the association of extremely high HDL-C with all-cause, atherosclerotic cardiovascular disease (CVD) mortality, and stroke risk. A systematic literature search in Embase, PubMed, Cochrane Library, and Web of Science was performed to collect relevant cohort studies published before August 20, 2022. A random-effects model was used to pool relative risks (RRs) and 95% confidence intervals (CIs). A total of 17 cohort studies involving 19,630,829 participants were included, encompassing 18,547,132 total deaths (1,328,036 CVD deaths). All-cause mortality, CVD mortality, and stroke risk in the extremely high HDL-C group were increased by 15% (RR = 1.15, 95% CI:1.05-1.25), 14% (RR = 1.14, 95% CI:0.96-1.35) and 14% (RR = 1.14, 95% CI:0.82-1.58), compared to the normal HDL-C group. In subgroup analyses, extremely high HDL-C was associated with a reduced risk of CVD mortality in women and a lower risk of stroke in men compared to normal HDL-C levels. The extremely high levels of HDL-C were associated with elevated risks of all-cause mortality, CVD mortality, and stroke. More well-designed studies are needed to confirm our findings. https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=370201, identifier: CRD42022370201.

ALDH2 rs671 Polymorphism Likely a Risk Factor for Hemorrhagic Stroke: A Hospital-Based Study.

Hypertension is the main risk factor for hemorrhagic stroke. Aldehyde dehydrogenase 2 (ALDH2) may inhibit the occurrence of hypertension by anti-oxidative stress and vascular dilation. The purpose was to investigate the relationship of ALDH2 polymorphisms with hemorrhagic stroke in Hakka Chinese. A total of 329 patients with hemorrhagic stroke and 515 controls were enrolled, and medical records (smoking and drinking history, hypertension, and diabetes) were collected. The genotypes of ALDH2 rs671 of the two groups were detected and analyzed. The proportion of the ALDH2 rs671 G/G, G/A, and A/A genotype in patients with hemorrhagic stroke was 55.9%, 37.4%, and 6.7%, respectively, while those were 65.0%, 30.7%, and 4.3% in controls, respectively. There was statistically significant difference in ALDH2 rs671 genotypes distribution (P=0.021) and alleles distribution (P=0.005) between patients and controls. Among hemorrhagic stroke patients, no statistically significant differences were observed between patients with ALDH2 different genotypes. Logistic regression analysis showed that there was significantly high risk of hemorrhagic stroke in men (male vs female: adjusted OR 1.711, 95% CI 1.154-2.538, P=0.008), the presence of hypertension (with vs without hypertension: adjusted OR 16.095, 95% CI 10.958-23.641, P<0.001), and the presence of ALDH2 rs671 G/A genotype (G/A vs G/G: adjusted OR 1.679, 95% CI 1.151-2.450, P=0.007) or A/A genotype (A/A vs G/G: adjusted OR 2.516, 95% CI 1.132-5.591, P=0.024). ALDH2 rs671 polymorphism likely a risk factor for hemorrhagic stroke.

The association between HDL-C and stroke in the middle-aged and elderly: A cross-sectional study.

Previous epidemiological studies have indicated that high-density lipoprotein cholesterol (HDL-C) is inversely associated with the risk of cardiovascular disease. However, this issue has aroused controversy in recent years. Besides, the relationship between HDL-C and the risk of total stroke in sex and race is less clear. Thus, we aimed to examine the association between different ranges of HDL-C and the risk of total stroke in adults over 40 years old. This cross-sectional study was conducted on a sample of 8643 participants (4222 men and 4421 women) aged ≥40 years old from the National Health and Nutrition Examination Survey 2007-2016. HDL-C was an independent variable and stroke was a dependent variable in this study, with the other variables as potential effect modifiers. To examine the associations between them, we used multivariate logistical regression models and smooth curve fittings, as well as subgroup analyses. HDL-C was inversely associated with stroke when HDL-C was less than 1.55mmol/L (odds ratio [OR]=0.36, 95% confidence interval [CI] :0.21-0.62, p<.05). However, above 1.55mmol/L, the incidence of stroke was not significant (OR=1.29, 95% CI: 0.79-2.09, p>.05). Stratified by race/ethnicity and sex, the subgroup analyses demonstrated that HDL-C was inversely associated with stroke in men and Whites, but no significant differences among women, Mexicans, blacks, and other races. We found a nonlinear relationship between HDL-C and total stroke. Our study reveals a range of inverse associations between HDL-C and stroke (HDL-C<1.55mmol/L), especially among men and Whites. This finding suggested that maintaining an appropriate HDL-C range may be beneficial in reducing the incidence of stroke.

Stroke Recurrence Following 28 Days After First Stroke in Men and Women 2012 to 2020: Observations From the Swedish Stroke Register.

Background Stroke incidence, care, and survival show continuous improvements in Sweden, including no or decreasing disparities between men and women. In this study, we aimed to estimate and compare the risk of stroke recurrence in men and women over time, accounting for the competing risk of death. Methods and Results We included adult patients with first-time stroke (ischemic or intracerebral hemorrhage) registered in Riksstroke (the Swedish Stroke Register), 2012 to 2020, and followed until December 2020. Stroke recurrences included new events registered in Riksstroke from 28 days after stroke. To account for the competing risk of death, we used the cumulative incidence function to estimate crude incidences, and multivariable Cox regression to estimate cause-specific hazard ratios (HRs) adjusting for differences in patients' risk factor profiles. The study included 72 148 (53.5%) men and 62 689 (46.5%) women. We observed 10 925 stroke recurrences and 81 811 deaths following the initial 28 days after the first stroke. The cumulative incidence of stroke recurrence was 3.7% (95% CI, 3.6-3.8) after 1 year, 7.0 (95% CI, 6.8-7.1) after 3 years, and 9.1% (95% CI, 8.9-9.3) after 5 years. The incidence decreased substantially during the study period (HR, 2019-2020 versus 2012, 0.824 [95% CI, 0.759-0.894]). Overall, men had a lower risk of stroke recurrence. After adjustments for differences in patient characteristics, men had a slightly higher risk of recurrence (of any type) after an ischemic stroke (HR, 1.090 [95% CI, 1.045-1.138]) and a lower risk after hemorrhagic stroke (HR, 0.880 [95% CI, 0.781-0.991]) compared with women. Conclusions The risk of stroke recurrence has decreased in both men and women. Women's higher age and other differences in risk factors partly explain their higher risk of stroke recurrence compared with men.

Prognostic factors of prolonged disorder of consciousness after stroke: A single centre retrospective study

BackgroundStroke is a common disease in neurology, which often causes prolonged disorder of consciousness (pDOC) and brings a heavy burden to the patient's family and society. This study aims to explore the epidemiological factors of pDOC after stroke and the factors affecting the outcome of consciousness. MethodThe patients that admitted in Tianjin Huanhu Hospital from January 2019 to December 2021 and met the inclusion criteria were selected. Descriptive statistics was initially performed on the relevant factors of the stroke group, and statistical analysis was subsequently performed. Finally, to judge the sensitivity and specificity of the significant factors to the prediction of outcome, the receiver operating characteristic (ROC) curve of the participants was used. ResultThe statistical results showed that the location of brain injury (λ2 = 7.550, P = 0.023), cerebral hernia (λ2 = 7.534, P = 0.006), and Glasgow Coma Scale (GCS) score at onset (t = −2.479, P = 0.017) were statistically significant indicators in the improvement of consciousness in patients with pDOC after stroke. The ROC curve showed that the sensitivity and specificity of predicting the outcome of brain injury site (area under the curve [AUC] = 0.766, 95% confidence interval [CI]: 0.708–0.824) were 0.50 and 0.90, respectively, and that of cerebral hernia (AUC = 0.663, 95% CI: 0.594–0.732) were 0.73 and 0.60, respectively. The GCS score (AUC = 0.660, 95% CI: 0.596–0.724) predicted the outcome with sensitivity and specificity of 0.35 and 0.92, respectively. ConclusionThe incidence rate of pDOC after stroke in men was higher than that in women, and the improvement rate in the consciousness level was significantly higher than that of ischemic–hypoxic encephalopathy. However, the improvement rate of the consciousness level in patients with pDOC after stroke was not related to age and gender. Cerebral hernia occurred at the time of onset, stroke occurred in the brainstem, and the low GCS score at the time of onset was significantly associated with the poor prognosis of consciousness level.

Risk factors and prognosis for heart failure in atrial fibrillation subtypes in women and men

Abstract Background Atrial fibrillation (AF) and heart failure (HF) are common diseases that often co-exist and substantially impact both morbidity, mortality, and quality of life. Although there has been an increasing amount of research on HF in AF patients, there is limited knowledge on the association of AF subtypes (paroxysmal/persistent, permanent) with HF in women and men. Purpose To explore the sex-specific association between incident AF subtypes and HF risk factors and mortality in AF participants in a general population. Methods A total of 14,798 women and 13,197 men aged 25 years and older were enrolled from 1994 to 2008 and followed up for incident AF and HF through 2016. Cox proportional hazards regression analysis was conducted to provide sex- and AF subtype-specific hazard ratios (HRs) for the risk of HF, risk factors for HF and joint influence on mortality when AF precedes HF. Participants without AF and HF were used as reference. In the analysis of risk factors for HF we included only those who developed AF, and the follow-up period started at the date of first detected AF. Models were adjusted for systolic blood pressure, body mass index (BMI), total cholesterol, current smoking, physical activity, and history of myocardial infarction, angina pectoris, stroke, and diabetes mellitus, as well as age, with age as the time scale in the regression models. Results Over a median follow-up of 21.6 years, incident AF occurred in 856 women (471 with paroxysmal/persistent AF and 385 with permanent AF) and 1,036 men (587 with paroxysmal/persistent AF and 449 with permanent AF). Incident HF occurred in 761 women and 930 men. In both sexes, there was an increased risk of HF when AF was present. For permanent AF, women had a significantly higher risk of HF than men (HR 10.50, 95% CI 8.72–12.66 vs. HR 8.11, 95% CI 6.81–9.67). Permanent AF, current smoking, and prevalent myocardial infarction were significant risk factors for HF in AF participants in both sexes, while hypertension was only associated with increased risk of HF in women and BMI and prevalent stroke in men. Higher physical activity level was associated with reduced risk of AF in both sexes. The risk of death increased when HF succeeded AF. For women the risk of mortality was higher for permanent AF (HR 3.83, 95% CI 3.19–4.61 vs. HR 2.98, 95% CI 2.34–3.80), while in men it was highest for paroxysmal/persistent AF (HR 3.67, 95% CI 2.94–4.58 vs. HR 2.91, 95% CI 2.37–3.57), but there was no significant difference between sexes. Conclusions All AF subtypes were associated with an increased risk of HF in both sexes. For permanent AF, women had a significantly higher risk than men. Several risk factors for HF in AF participants were similar between sexes. However, hypertension was only a risk factor in women, whereas BMI and prevalent stroke were only risk factors in men. In AF participants, subsequent development of HF was associated with increased mortality in both sexes. Funding Acknowledgement Type of funding sources: Public Institution(s).

Sex Differences in Stroke Risk Factors, Clinical Profiles, and In-Hospital Outcomes Among Stroke Patients Admitted to the Medical Ward of Dessie Comprehensive Specialized Hospital, Northeast Ethiopia.

BackgroundA stroke is a vascular accident that affects both men and women. The threat of stroke and outcome status differ between the sexes. Such data are lacking in Ethiopia. Therefore, this study assessed sex differences in stroke risk factors, clinical profiles, and outcomes in the medical ward of Dessie comprehensive specialized hospital.MethodsA retrospective cross-sectional study was employed among stroke patients. Medical records with complete information and a confirmed diagnosis of stroke using imaging techniques were included in the study. Using simple random sampling, 344 medical records were selected, 312 of which fulfilled the inclusion criteria. Bivariate and multivariate logistic regression analyses and a chi-square test were employed. The frequency, percentage, and mean and standard deviation of the variables were described using descriptive statistics. Findings with a P-value <0.05 were considered statistically significant.ResultsMost of the patients were above or equal to 45 years old in both sexes. A significantly higher number of male than female patients were aged less than 45 years (p-value-0.001). Younger age (AOR: 2.998, p = 0.000), cigarette smoking (AOR: 2.911, p = 0.009), and Khat chewing (AOR: 3.650, p = 0.001) were risk factors for stroke in males. A higher number of males presented with hemiplegia/hemiparesis 89 (28.5%), aphasia 45 (14.4%), and facial palsy 19 (6.1%). However, more females were unconscious (15.1%). Significant differences were not seen in the stroke outcomes. Furthermore, there were no apparent differences in risk factors for stroke-related mortality.ConclusionMales developed stroke at a younger age. Women were older at the time of stroke onset and presented unconscious. More males experienced hemiplegia/hemiparesis, aphasia, and facial palsy. Smoking, drinking, and khat chewing were risk factors for stroke in men. There were no gender differences in the stroke death rate. Therefore, educating the public about stroke risk factors, lifestyle modification, and conducting prospective research is required.
