- Background: The diagnostic work-up to reveal etiology in a young ischemic stroke (IS) patient includes evaluation for high-risk source of cardioembolism (HRCE), since this subtype associates with high early recurrence rate and mortality. We investigated the association of ECG findings with a final etiologic subgroup of HRCE in a cohort of young patients with first-ever IS. Methods: The Helsinki Young Stroke Registry includes IS patients aged 15 to 49 years admitted between 1994 and 2007. Blinded to other clinical data, we analyzed a 12-lead resting ECG obtained 1-14 days after the onset of stroke symptoms in 690 patients. We then compared the ECG findings between a final diagnosis of HRCE (n = 78) and other/undetermined causes (n = 612). We used multivariate logistic regression to study the association between ECG parameters and HRCE. Results: Of our cohort (63% male), 35% showed ECG abnormality, the most common being T-wave inversion (16%), left ventricular hypertrophy (14%), prolonged P-wave (13%), and prolonged QTc (12%). 3% had atrial fibrillation (AF), and 4% P-terminal force (PTF). Of the continuous parameters, longer QRS-duration, QTc, and wider QRS-T-angle independently associated with HRCE. After AF, PTF had the strongest independent association with HRCE (odds ratio = 44.32, 95% confidence interval = [10.51-186.83]), followed by a QRS-T angle > 110 degrees (8.29 [3.55-19.32]), T-wave inversion (5.06, 2.54-10.05), and prolonged QTc (3.02 [1.39-6.56]). Conclusion: Routine ECG provides useful information for directing the work-up of a young IS patient. In addition to AF, PTF in particular showed a strong association with etiology of HRCE.

- Background and Purpose-Cancer is a risk factor for ischemic stroke. Little is known about cancer among young adults with ischemic stroke. We studied the frequency of cancer and its association with long-term risk of death among young patients with first-ever ischemic stroke. Methods-1002 patients aged 15 to 49 years, registered in the Helsinki Young Stroke Registry, and with a median follow-up of 10.0 years (interquartile range 6.5-13.8) after stroke were included. Historical and follow-up data were derived from the Finnish Care Register and Statistics Finland. Survival between groups was compared with the Kaplan-Meier life-table method, and Cox proportional hazard models were used to identify factors associated with mortality. Results-One or more cancer diagnosis was made in 77 (7.7%) patients, of whom 39 (3.9%) had cancer diagnosed prestroke. During the poststroke follow-up, 41 (53.2%) of the cancer patients died. Median time from prestroke cancer to stroke was 4.9 (1.0-9.5) years and from stroke to poststroke cancer was 6.7 (2.7-10.9) years. Poststroke cancer was associated with age >40 years, heavy drinking, and cigarette smoking. The cumulative mortality was significantly higher among the cancer patients (68.6%, 95% confidence interval 52.0%-85.3%) compared with patients without cancer (19.7%, 95% confidence interval 16.3%-23.2%). Active cancer at index stroke, melanoma, and lung/respiratory tract cancer had the strongest independent association with death during the follow-up when adjusted for known poststroke mortality prognosticators. Conclusions-Cancer, and especially active cancer and no other apparent cause for stroke, is associated with unfavorable survival among young stroke patients.

- Objectives:To study the long-term risk of recurrent cardiac, arterial, and venous events in young stroke patients, and whether these risks differed between etiologic subgroups.Methods:The study population comprised 970 patients aged 15-49 years from the Helsinki Young Stroke Registry (HYSR) who had an ischemic stroke in 1994-2007. We obtained follow-up data until 2012 from the Finnish Care Register and Statistics Finland. Cumulative 15-year risks were analyzed with life tables, whereas relative risks and corresponding confidence intervals (CI) were based on hazard ratios (HR) from Cox regression analyses.Results:There were 283 (29.2%) patients with a cardiovascular event during the median follow-up of 10.1 years (range 0.1-18.0). Cumulative 15-year risk for venous events was 3.9%. Cumulative 15-year incidence rate for composite vascular events was 34.0 (95% CI 30.1-38.2) per 1,000 person-years. When adjusted for age and sex, patients with an index stroke caused by high-risk sources of cardioembolism had the highest HR for any subsequent cardiovascular events (3.7; 95% CI 2.6-5.4), whereas the large-artery atherosclerosis group had the highest HR (2.7; 95% CI 1.6-4.6) for recurrent stroke compared with patients with stroke of undetermined etiology.Conclusions:The risk for future cardiovascular events after ischemic stroke in young adults remains high for years after the index stroke, in particular when the index stroke is caused by high-risk sources of cardioembolism or large-artery atherosclerosis.

- OBJECTIVE: We aimed to investigate the proportion of young patients not returning to work (NRTW) at 1 year after ischemic stroke (IS) and during follow-up, and clinical factors associated with NRTW. METHODS: Patients from the Helsinki Young Stroke Registry with an IS occurring in the years 1994-2007, who were at paid employment within 1 year before IS, and with NIH Stroke Scale score ≤15 points at hospital discharge, were included. Data on periods of payment came from the Finnish Centre for Pensions, and death data from Statistics Finland. Multivariate logistic regression analyses assessed factors associated with NRTW 1 year after IS, and lasagna plots visualized the proportion of patients returning to work over time. RESULTS: We included a total of 769 patients, of whom 289 (37.6%) were not working at 1 year, 323 (42.0%) at 2 years, and 361 (46.9%) at 5 years from IS. When adjusted for age, sex, socioeconomic status, and NIH Stroke Scale score at admission, factors associated with NRTW at 1 year after IS were large anterior strokes, strokes caused by large artery atherosclerosis, high-risk sources of cardioembolism, and rare causes other than dissection compared with undetermined cause, moderate to severe aphasia vs no aphasia, mild and moderate to severe limb paresis vs no paresis, and moderate to severe visual field deficit vs no deficit. CONCLUSIONS: NRTW is a frequent adverse outcome after IS in young adults with mild to moderate IS. Clinical variables available during acute hospitalization may allow prediction of NRTW.

- Background: Our aims were to evaluate the response to salvage treatment in relation to initial treatment and to evaluate prognostic factors at the time of relapse in an unselected population of relapsing patients with Hodgkin's lymphoma (HL). Patients and methods: In total, 124 patients younger than 60 yr of age with initial diagnosis of HL in Sweden relapsed between 1985 and 1995. Results: Fifty-eight patients relapsed after initial treatment with radiotherapy (RT) only, 62 after combination chemotherapy (CT), of whom 30 had received additional involved-field RT, and four after a short course of CT followed by extended-field RT. For 37 patients among the 58 relapsers after initial RT treated according to the recommendations of the National guidelines, the 5-yr Hodgkin-specific survival (HLS) was 85%, overall survival (OS) 73% and event-free survival (EFS) 62%, which is not inferior to survival in patients with primarily advanced stages. It was poorer in the 21 patients who initially had received RT only, even though they had been recommended for more extensive treatment. For patients initially treated with a full course (6-8 cycles) of CT the 5-yr HLS was 60%, OS 58% and EFS 22%. Bulky disease and age at diagnosis strongly affected survival in a multivariate analysis. Conclusions: Patients initially treated with RT who relapse have a favourable outcome, provided they have been treated according to the recommendations of the guidelines at the time of diagnosis. Initially bulky disease and, as a consequence, additional RT as part of the initial treatment negatively affect survival at relapse in patients initially treated with a full course of CT.

- The development of intracerebral hemorrhage following intravenous thrombolysis (IVT) can be influenced by various confounders related to the underlying vessel and tissue conditions. There are some data on association of cause of the stroke and the hemorrhage transformation. We tested the hypothesis that the cause of stroke is associated with the development of symptomatic intracerebral hemorrhage (sICH) following IVT.A consecutive cohort of 2485 IVT-treated patients at the Helsinki University Central Hospital was classified according to the Trial of ORG 10172 in Acute Stroke Treatment (TOAST) criteria. An sICH was classified according to the European Cooperative Acute Stroke Study II criteria. The associations of sICH with nominal, ordinal and continuous variables were analyzed in a univariate binary regression model and adjusted in multivariate binary regression models.In univariate analyses, cardioembolism [odds ratio (OR), 1.14; 95% confidence interval (CI), 0.79-1.64] and large-artery atherosclerosis (OR, 1.30; 95% CI, 0.85-2.00) were not associated with sICH, and small-vessel occlusion was associated with lower odds for sICH (OR, 0.18; 95% CI, 0.06-0.57). When adjusted for previously identified factors associated with sICH, none of the TOAST categories was associated with a higher or lower frequency of sICH.The development of sICH in IVT-treated patients is not related to the cause of stroke.

- Background and Purpose-Cerebral white matter lesions (WMLs), a surrogate for small-vessel disease, are common in patients with stroke and may be related to an increased intracranial bleeding risk after intravenous thrombolysis in acute ischemic stroke. We aimed to investigate the risk of symptomatic intracerebral hemorrhage (sICH) in the presence of WMLs in a large cohort of ischemic stroke patients treated with intravenous thrombolysis. Methods-We included 2485 consecutive patients treated with intravenous thrombolysis at the Helsinki University Central Hospital. WMLs were scored according to 4 previously published computed tomography visual rating scales from all baseline head scans. A sICH was classified according to the European Cooperative Acute Stroke Study II criteria. The associations of sICH with nominal, ordinal, and continuous variables were analyzed in a univariate binary regression model and adjusted in multivariate binary regression models. Results-In univariate and multivariate regression analyses, all 4 tested visual WML rating scales (as continuous variables or dichotomized at different cutoff points) were associated with increased risk of sICH. In binary analyses, WML doubled the bleeding risk: the odds ratios of all 4 visual rating scales ranged from 2.22 (95% confidence interval, 1.49-3.30) to 2.70 (1.87-3.90) in univariable and from 2.00 (1.26-3.16) to 2.62 (1.71-4.02) in multivariable analyses. The multivariable-adjusted odds ratio for the association of high load of WMLs with remote parenchymal hemorrhage was 4.11 (2.38-7.10). Conclusions-WMLs visible on computed tomography are associated with a more than doubled risk of sICH in patients treated with intravenous thrombolysis for acute ischemic stroke.
