The aim of this study was to investigate the relationship between libido decrease at 2 weeks after stroke and recurrent stroke at 1-year. Methods: It is a multi-centered, prospective cohort study. The 14th item of the Hamilton Depression Rating Scale-17 was used to evaluate changes of libido in poststroke patients at 2 weeks. Stroke recurrence was defined as an aggravation of former neurological functional deficit, new local or overall symptoms, or stroke diagnosed at re-admission. Results: Among 2341 enrolled patients, 1757 patients had completed follow-up data, 533 (30.34%) patients had decreased libido at 2 weeks, and 166 (9.45%) patients had recurrent stroke at l-year. Multivariate logistic regression analysis showed that, compared with patients with normal libido, the odds ratio (OR) of recurrent stroke in patients with decreased libido was reduced by 4 l% (OR = 0.59, 95% confidence interval [CI]: 0.40-0.87). The correlation was more prominent among male patients (OR = 0.52, 95% CI: 0.31 0.85) and patients of≥60 years of age (OR = 0.57, 95% CI: 0.35-0.93). Conclusions: One out of three stroke patients in China's Mainland has decreased libido at 2 weeks after stroke. Decreased libido is a protective factor for stroke recurrence at 1-year, which is more prominent among older male patients.展开更多

The aim of this study was to find out the associations between cortex-involved stroke, vascular risk factors, and the subtypes (discovery time and duration) of AF. Methods: This was an imaging study of the China Atrial Fibrillation Screening in Acute Ischemic Stroke Patients (CRIST) trial. Between October 2013 and June 2015, 1511 acute ischemic stroke or transient ischemic attack (TIA) patients within 7 days after stroke onset at 20 Chinese hospitals were enrolled in this prospective, multicenter cohort, cross-sectional study. The final analysis of this sub-study included 243 patients with AF with required magnetic resonance imaging (MRI) sequences. AF was diagnosed by 6-day Holter monitoring and classified by duration of 24 h. Two stroke specialists blinded to the clinical information reviewed MRI (diffusion-weighted MRI). The third stroke specialists, also blinded to the clinical information, assessed the conflicts. Adjusted large artery atherosclerosis as confounding factor, the associations between cortex-involved lesions, vascular risk factors, and the subtype of AF were evaluated by univariate and multivariate regression analyses. Results: Of 243 acute ischemic stroke patients with AF, 190 were known AF and 53 were newly detected AF. There were 28 patients with AF persistent >24 h and 25 persistent ≤24 h in newly detected AF. Patients with newly detected AF were likely to have a fewer history of stroke or TIA (16.98% vs. 36.31%, P = 0.008) and lower fasting blood glucose (5.91 ± 1.83 mmol/L vs. 6.75 ± 3.83 mmol/L, P = 0.030) than patients with known AF. Among these 243 patients, 102 (41.98%) patients were with cortex-involved lesions. Cortex-involved lesions were significantly related to newly detected AF persistent >24 h (odds ratio [OR]: 4.517, 95% confidence interval [CI]: 1.490–13.696, P = 0.008), proteinuria (OR: 3.431, 95% CI: 1.530–7.692, P = 0.021), and glycosylated hemoglobin (OR: 0.632, 95% CI: 0.464–0.861, P = 0.004). Conclusions: Compared to previously known AF, newly detected AF persistent >24 h was associated with cortex-involved ischemic stroke.展开更多

文摘Introduction Vestibular migraine (VM), a common disorder with familiar predisposition, is characterized by recurrent episode of dizziness or vertigo and accompanying symptoms of nausea, vomiting, and/or headaches.The patients with VM may require neurologic, emergency, or otorhinolaryngologic services, and the disorder is often misdiagnosed with posterior circulation ischemia (PCI) or transient ischemic attack (TIA), peripheral vestibular vertigo, Meniere’s disease (MD), and multiple (lacunar) cerebral infarctions.Report from population-based study showed that the prevalence of VM was up to 1%,^[1] which was one of the common disorders causing dizziness/vertigo, and the rate of misdiagnosis was up to 80%.[2] Thus, a multidisciplinary expert consensus about the definition, characteristics, related work-ups, and diagnostic criteria is needed for the accurate diagnosis and standardized management.

文摘China faces the greatest challenge from stroke in the world.The death rate for cerebrovascular diseases in China was 149.49 per 100000,accounting for 1.57 million deaths in 2018.It ranked third among the leading causes of death behind malignant tumours and heart disease.The age-standardised prevalence and incidence of stroke in 2013 were 1114.8 per 100000 population and 246.8 per 100000 person-years,respectively.According to the Global Burden of Disease Study 2017,the years of life lost(YLLs)per 100000 population for stroke increased by 14.6%;YLLs due to stroke rose from third highest among all causes in 1990 to the highest in 2017.The absolute numbers and rates per 100000 population for all-age disability-adjusted life years(DALYs)for stroke increased substantially between 1990 and 2017,and stroke was the leading cause of all-age DALYs in 2017.The main contributors to cerebrovascular diseases include behavioural risk factors(smoking and alcohol use)and pre-existing conditions(hypertension,diabetes mellitus,dyslipidaemia and atrial fibrillation(AF)).The most prevalent risk factors among stroke survivors were hypertension(63.0%-84.2%)and smoking(31.7%-47.6%).The least prevalent was AF(2.7%-7.4%).The prevalences for major risk factors for stroke are high and most have increased over time.Based on the latest national epidemiological data,26.6%of adults aged≥15 years(307.6 million adults)smoked tobacco products.For those aged≥18 years,age-adjusted prevalence of hypertension was 25.2%;adjusted prevalence of hypercholesterolaemia was 5.8%;and the standardised prevalence of diabetes was 10.9%.For those aged≥40 years,the standardised prevalence of AF was 2.31%.Data from the Hospital Quality Monitoring System showed that 3010204 inpatients with stroke were admitted to 1853 tertiary care hospitals during 2018.Of those,2466785(81.9%)were ischaemic strokes(ISs);447609(14.9%)were intracerebral haemorrhages(ICHs);and 95810(3.2%)were subarachnoid haemorrhages(SAHs).The average age of patients admitted was 66 years old,and nearly 60%were male.A total of 1555(0.1%),2774(0.6%)and 1347(1.4%)paediatric strokes(age<18 years)were identified among IS,ICH and SAH,respectively.Over one-third(1063892(35.3%))of the patients were covered by urban resident basic medical insurance,followed by urban employee basic medical insurance(699513(23.2%))and new rural cooperative medical schema(489361(16.3%)).The leading risk factor was hypertension(67.4%for IS,77.2%for ICH and 49.1%for SAH),and the leading comorbidity was pneumonia or pulmonary infection(10.1%for IS,31.4%for ICH and 25.2%for SAH).In-hospital death/discharge against medical advice rate was 8.3%for stroke inpatients,ranging from 5.8%for IS to 19.5%for ICH.The median and IQR of length of stay was 10.0(7.0-14.0)days,ranging from 10.0(7.0-13.0)in IS to 14.0(8.0-22.0)in SAH.Data from the Chinese Stroke Center Alliance demonstrated that the composite scores of guideline-recommended key performance indicators for patients with IS,ICH and SAH were 0.77±0.21,0.72±0.28 and 0.59±0.32,respectively.
