<b><i>Introduction:</i></b> The purpose of this study was to investigate seasonal variation in stroke incidence using data from a large-scale stroke registry of general population in current Japan. <b><i>Methods:</i></b> Shiga Stroke Registry (SSR) is an ongoing population-based registry of stroke that occurred in the Shiga Prefecture in central Honshu, Japan. A total 6,688 cases of first-ever stroke, with onset dates ranging from 1 January 2011 to 31 December in 2013 were included in this study. Incidence rates of first-ever stroke in each season were estimated using the person-year approach and adjusted for age and sex using the Poisson regression models. <b><i>Results:</i></b> From 2011 to 2013, we identified a total of 6,688 stroke cases (3,570 men, 3,118 women), of which 4,480 cases had ischemic stroke (2,518 men, 1,962 women), 1,588 had intracerebral hemorrhage (857 men, 731 women) and 563 had subarachnoid hemorrhage (166 men, 397 women). Age- and sex-adjusted incidence rates of total stroke were 151 (95% confidence interval [CI] 144–160, <i>p</i> = &#x3c;0.001 vs. summer) in spring, 130 (95% CI 122–137) in summer, 141 (95% CI 133–149, <i>p</i> = 0.020 vs. summer) in autumn and 170 (95% CI 161–179, <i>p</i> = &#x3c;0.001 vs. summer) in winter. Seasonal variation was more pronounced in intracerebral hemorrhage than in ischemic stroke. <b><i>Conclusion:</i></b> In the present large-scale stroke registry of general population, incidence rates of stroke were highest in winter and lowest in summer in current Japan.

<b><i>Introduction:</i></b> Stroke is associated with major consequences in terms of socioeconomic impact and lost disability-adjusted life in young victims, thus justifying a careful surveillance of epidemiological trends. This study aimed to assess changes in the incidence of ischemic stroke in young adults over a long period. <b><i>Methods:</i></b> All cases of first-ever ischemic stroke that occurred among adults aged 18–55 years were prospectively recorded using the population-based Dijon Stroke Registry, from 1985 to 2017. Sex-specific annual incidence rates were calculated and were presented according to 6 time periods. Incidence rate ratios (IRRs) were determined to assess sex differences in stroke incidence. <b><i>Results:</i></b> Over the whole study period, 4,451 patients suffered a first-ever ischemic stroke. Among these patients, 469 (10.5%) were young adults (median age: 46 years, IQR: 39–50; 53.9% men). Incidence rates rose from the study period 2003 to 2007 compared with previous periods and remained stable thereafter, both in men and women. Hence, incidence per 100,000 per year was globally 11.0 (95% CI: 9.4–12.7) before 2003 and 22.9 (20.3–25.6) thereafter. In individuals aged 18–45 years, incidence rates were 5.4 (4.3–6.9) overall, 4.1 (2.7–6.0) in men, and 6.7 (4.9–9.0) in women, before 2003. After 2003, incidence rates rose to 12.8 (10.7–15.1) overall, 12.0 (9.2–15.4) in men, and 13.6 (10.6–17.0) in women. In this age group, the men/women IRR was 0.78 (95% CI: 0.62–1.26, <i>p</i> = 0.08), although sex differences decreased over time (IRR = 0.62; 95% CI: 0.36–1.02, <i>p</i> = 0.046 before 2003, vs. IRR = 0.88; 95% CI: 0.62–1.26, <i>p</i> = 0.48 after 2003). In individuals aged 45–55 years, incidence rates before 2003 were 47 (37–61) in men and 25 (17–35) in women (IRR = 1.90; 95% CI: 1.24–2.97, <i>p</i> &#x3c; 0.001), and they increased to 82 (67–100) in men and 46 (35–59) in women (IRR = 1.79; 95% CI: 1.29–2.49, <i>p</i> &#x3c; 0.001) after 2003. <b><i>Conclusions:</i></b> The incidence of ischemic stroke in young adults increased during the early 2000s and remained stable thereafter. These results highlight the priority need for dedicated prevention strategies for the young to reduce the burden of stroke.

Diagnostic Codes

Background: Over 2 million people under age 50 are seen in a U.S. emergency room monthly for non-fatal injuries. Our objective was to measure ischemic stroke incidence after traumatic injury in young patients and identify stroke risk factors. Methods: We performed a population-based study of ischemic stroke after trauma among people <50 years old in a Northern Californian integrated health care system. We electronically identified a cohort of patients with diagnostic codes for trauma (ICD-9 800-959.9) in emergency and inpatient encounters from 1997-2011, then identified ischemic stroke outcomes within 4 weeks. To determine stroke, we required an ICD-9 stroke code (433-438) plus a radiology report of brain imaging containing a keyword: stroke, infarct#, thromb#, ischemi#, lacun#, or dissect#. A neurologist reviewed the reports to exclude those inconsistent with ischemic stroke. We obtained clinical data such as injury type from electronic databases to calculate stratified incidence rates and risk ratios. Results: From 1.5 million trauma encounters, we identified 197 ischemic strokes. The 4-week stroke incidence after any traumatic injury was 0.013% (95% CI 0.011, 0.015). Patients with stroke had a mean age of 37.7 years (SD 12.2) versus 24.0 years (SD 13.8) in those without stroke (P<0.0001). Patients with injury to the head or neck were more likely to have a stroke compared to those with other types of injuries (Table). The 4-week stroke incidence after head or neck injury was 0.07% (95% CI 0.05, 0.09) among adults and 0.005% (95% CI 0.001, 0.01) among children (P<0.0001). Of the 197 stroke cases, 16% (95% CI 11, 22) had a diagnostic code for cranio-cervical dissection. Conclusions: A 4-week stroke incidence of 0.013% suggests that 260 young people have an ischemic stroke after a traumatic injury every month in the U.S. Further research is needed to identify the highest risk groups, such as those with head or neck injury, and opportunities for stroke prevention.

Background: Chemotherapy is suspected to be a risk factor for stroke in patients with cancer, athough the results from large-scale studies are controversial. Few strategies are available for reducing the stroke-related risks.Methods: We analyzed stroke incidence rates in Taiwan’s Longitudinal Health Insurance database 2000 (LHID2000) for patients aged ≥20 years with newly-diagnosed cancer between Jan 1, 2000 and Dec 31, 2006, who did or did not receive chemotherapy. Moreover, we compared stroke incidence rates among chemotherapy users who did or did not use traditional Chinese medicine. All study participants were followed-up for 5 years or until they had a stroke.Results: In adjusted Kaplan-Meier analysis, the incidence of stroke was higher within the first year of cancer diagnosis among chemotherapy recipients compared with those who did not receive chemotherapy (31.1 vs. 9.75; adjusted subdistribution hazard ratio [sHR] 2.21; 95% confidence interval [CI], 1.52–3.20; p &lt; 0.001). This between-group difference persisted at 4 years of follow-up (13.6 vs. 5.42; adjusted sHR 1.94; 95% CI, 1.53–2.46; p &lt; 0.001). Similarly, the 5-year incidence rate of stroke was significantly lower among chemotherapy recipients using TCM vs. non-TCM users (0.19 vs. 0.46; adjusted sHR 0.45; 95% CI, 0.26–0.79; p &lt; 0.001), as was the mortality rate (adjusted sHR 0.55; 95% CI, 0.44–0.68; p &lt; 0.001).Conclusion: These Taiwanese data suggest that chemotherapy is a risk factor for stroke and that the use of TCM can significantly mitigate this risk. TCM also appears to reduce the mortality risk associated with chemotherapy.

Background and Purpose— Ischemic stroke incidence has declined in industrialized countries the last decades, with possible exception for the youngest age groups. We estimated age- and sex-specific trends in incidence and case fatality of first-ever ischemic stroke between 1977 and 2010 in a Norwegian municipality. Methods— Age-adjusted time trends in incidence from 1977 to 2010 were estimated by fractional polynomial and Poisson regression, and case fatality by logistic regression in 36 575 participants of the population-based Tromsø Study. Results— There were 1214 first-ever ischemic strokes within a total follow-up time of 611 176 person-years. The overall age- and sex-adjusted incidence decreased by 24% in 1995 to 2010. In women aged 30 to 49 years, the incidence increased significantly from 1980 to 2010. In men aged 30 to 49 years, there was a nonsignificant, rising trend from 1977 to 2010. Men aged 50 to 64 years had similar incidence in 2010 compared with 1989. From the mid-1990s to 2010, the incidence declined significantly in women aged 50 to 74 years and in men aged 65 to 74 years, but remained stable in those aged ≥75 years. Case fatality decreased significantly in men aged 30 to 84 years from 1995 to 2010, whereas there was no significant change in women. Conclusions— Age-adjusted incidence of first-ever ischemic stroke increased in young women, declined in women aged 50 to 74 years and men aged 65 to 74 years and remained stable among the oldest. Case fatality declined in men aged 30 to 84 years, but not in women.

Objective: The aim of this nationwide age- and sex- matched longitudinal follow up study is to determine the risk of Parkinson’s disease (PD) associated with ischemic stroke in Korea.Methods: Patient data were collected from the National Health Insurance Service-National Health Screening Cohort (NHIS-HEALS). PD was identified using the International Classification of Diseases (ICD) 10-CM code G 20. In total, 6,475 patients were enrolled in the PD group from the NHISS. After subtracting 1,039 patients who underwent hospitalization less than once or those who visited an outpatient clinic less than two times, 5,259 patients who were diagnosed after January 1, 2004 ultimately participated in this study. After case-control match was done through 1:5 age- and sex- stratified matching, 26,295 individuals were chosen as control. Kaplan-Meier method and Cox proportional hazard regression analysis were performed to evaluate the risk of ischemic stroke in PD.Results: The hazard ratio of ischemic stroke in the PD group was 3.848 (95% confidence interval (confidence interval [CI]): 3.14-4.70) after adjusting for age and sex. The adjusted hazard ratio of ischemic stroke in PD group was 3.885 (95% CI: 3.17-4.75) after adjusting for comorbidities. According to subgroup analysis, in male and female and non-diabetes and diabetes and non-hypertension and hypertension and dyslipidemia and non-dyslipidemia subgroups, ischemic stroke incidence rates were significantly higher in the PD group than those in the control group.Conclusions: This nationwide longitudinal study suggests an increased risk of ischemic stroke in PD patients.

Numerous hospital-based stroke registries have been developed in Iran during last decade. Khorasan Stroke Registry, Khorasan Posterior Circulation Stroke Registry, Khorasan Pediatric Stroke Registry and Khorasan Stroke in Young Adults Registry are among these published registries. Meanwhile, There is only one epidemiologic deigned study of stroke in Iran and Middle East. Based on this standard epidemiologic study; The crude annual incidence rate of First Ever Stroke (FES) is 139 (95% CI, 128 to 149) per 100 000; for men, 144 (95% CI, 128 to 159), and for women, 133 (95% CI, 118 to 148). The incidence rates increases significantly with each decade of life and is similar in men and women. Subtypes of FES in 81.9%  of patients is ischemic stroke,12.7% is intracerebral hemorrhage, and 2.4% have subarachnoid hemorrhage. The crude annual incidence rate per 100 000 inhabitants is 113 (95% CI, 104 to 123) for ischemic stroke, 18 (95% CI, 14 to 21) for intracerebral hemorrhage and 3 (95% CI, 2 to 5) for subarachnoid hemorrhage. Ischemic strokes are occurring approximately 1 decade earlier in Iran than in other countries.

Background: Hemorrhagic transformation (HT) of ischemic stroke can have devastating consequences, leading to longer hospitalizations, increased morbidity and mortality. We sought to identify the rate of HT in stroke patients not treated with tPA within a large, biracial population. Methods: The GCNKSS is a population-based stroke epidemiology study from five counties in the Greater Cincinnati region. During 2015, we captured all hospitalized strokes by screening ICD-9 codes 430-436 and ICD-10 codes I60-I68, and G45-46. Study nurses abstracted all potential cases and physicians adjudicated cases, including classifying the degree of HT. Patients treated with thrombolytics were excluded. Incidence rates per 100,000 and associated 95% confidence intervals (CI) were estimated for HT cases, age and sex adjusted to the 2000 US population. Multiple logistic regression was used to examine risk factors associated with HT. Results: In 2015, there were 2301 ischemic strokes included in the analysis. Of these 104 (4.5%) had HT; 23 (22.1%) symptomatic, 55 (52.9%) asymptomatic and 26 (25%) unknown. Documented reasons for not receiving tPA in these patients were: time (71, 68.3%), anticoagulant use (1, 1.0%), other (18,17.3%) and unknown (14, 13.5%), which were not significantly different compared to those without HT. Only 29/104 (18.3%) had HT classified as PH-1 or PH-2. The age, sex and race-adjusted rate of HT was 9.8 (7.9, 11.6) per 100,000. The table shows rates of potential risk factors and the adjusted odds of developing HT. 90 day all-cause case fatality for patients with HT was significantly higher, 27.9% vs. 15.7%, p<0.0001. Conclusion: We found that 4.5% of non-tPA treated IS patients had HT. These patients had more severe strokes, were more likely to have abnormal coagulation tests or anticoagulant use, and were more likely to die within 90 days. We also report the first population-based incidence rate of HT in non-tPA treated of 9.8/100,000, a rate similar to the incidence of SAH.

Antidepressant Use

Introduction: SSRIs, the most commonly prescribed antidepressants (AD) in the US, are linked to an increased intracerebral hemorrhage (ICH) risk possibly related to impaired platelet function. In the Florida Stroke Registry (FSR), we studied the proportion of cases presenting with ICH amongst AD users and the rate of SSRI prescription amongst stroke patients discharged on AD. Methods: From Jan 2010 to Dec 2019 we included 127,915 cases from FSR in whom information on AD use was available. Multivariable logistic regression was used to evaluate ICH proportions amongst AD and non-AD users and rates of prescribed SSRIs at discharge. Results: The rate of ICH amongst prior AD users (n=17,009, median age 74, IQR=19) and non-AD users (n=110,906, median age 72, IQR=21) were 11% and 14% respectively. Prior AD users were more likely to be female (17% vs. 10% male), non-Hispanic White (16% vs. 8% non-Hispanic Black vs. 12% Florida Hispanic vs. 6% Puerto Rican Hispanic), have hypertension (HTN) (14.% vs. 10%), diabetes mellitus (DM) (16% vs.12%), use oral anticoagulants (OAC) (17 % vs. 13%), antiplatelets (AP; 17% vs. 11%), and statins (17% vs. 10%) prior to hospital presentation. In multivariable analysis adjusting for age, race, prior history of HTN, DM, prior OAC, AP and statin use, AD users just as likely to present with spontaneous ICH as compared to non-AD users (OR=0.92, 95% CI 0.85, 1.01). A total of 3.4% of all ICH patients and 9% of those in whom AD information was available were discharged home on an AD (74 % SSRI, 24% other AD). Conclusion: In this large population-based study, we did not find an association between prior AD use and an increased rate of ICH. Importantly AD (mostly SSRIs) are commonly prescribed to patients with ICH in routine clinical practice. The association between types, duration, and safety of antidepressant use in ICH patients deserves further studies.
