- 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.

Journal article (peer-reviewed)abstract
- Introduction: Scarce data exist on the etiology of recurrent ischemic strokes (ISs) among young adults. We analyzed the etiology of first-ever and recurrent events and the differences between them.Patients and methods: Patients aged 15-49 years with a first-ever IS in 1994-2007 were included in the Helsinki Young Stroke Registry. In this retrospective cohort study, data on recurrent ISs were identified from Care Register for Health Care until the end of 2017 and Causes of Death Register and from patient records until the end of 2020. All first-ever and recurrent ISs were classified using Atherosclerosis-Small vessel disease-Cardioembolism-Other Cause (A-S-C-O) and Trial of Org 10172 in Acute Stroke Treatment (TOAST) classifications.Results: A total of 970 patients were included (median age at index IS 46 years, interquartile range 43-48, 33% women), of which 155 (16.0%) patients had recurrent IS, with 8 (5.2%) fatal cases and 5 (3.2%) unverifiable cases. The median follow-up was 17.4 (IQR 13.9-21.7) years. Median time from the index event to the first recurrent event was 4.5 (interquartile range [IQR] 1.6-10.2) years. Recurrence was more often due to definite cardioembolism (10.7% vs 18.0%, p = 0.013), while the proportion of other definite A-S-C-O subgroups remained the same. With TOAST classification, the proportion of true cryptogenic ISs decreased (16.7% vs 6.7%, p = 0.003), while those with incomplete evaluation increased (9.3% vs 19.3%, p = 0.015). Other TOAST phenotypes remained the same.Conclusion: The proportion of definite cardioembolism increased at recurrence using the A-S-C-O classification and the number of cryptogenic ISs decreased using the TOAST classification, while cases with incomplete evaluation increased. Most etiologies remained the same.

- Introduction: Limited data exist on the outcome of pregnancies and deliveries in women with ischaemic stroke. We investigated the incidence of pregnancy- and delivery-related complications in women with ischaemic stroke before and after pregnancy compared with stroke-free matched controls. Patients and methods: Of our 1008 consecutive patients aged 15–49 years with first-ever ischaemic stroke, 1994– 2007, we included women with pregnancy data before or after stroke recorded in the Medical Birth Register (MBR) (n¼152), and for them searched stroke-free controls matched by age, parity, year of birth, residential area and multiplicity (n¼608). Data on hospital admissions and deaths (1987–2014) came from national health registries. Poisson regression mixed models allowed comparison of the incidence of complications. Results: A total of 124 stroke mothers had 207 singleton pregnancies before and 45 mothers 68 pregnancies after stroke. The incidence rate ratio (IRR) for the composite outcome of pregnancy and delivery complications adjusted for socioeconomic status and maternal smoking was 1.43 (95% confidence interval [CI] 1.00–2.03, p¼0.05) for pre-stroke mothers, and 1.09 (95% CI 0.66–1.78) for post-stroke mothers, compared with matched controls. Similarly, the adjusted IRR for post-stroke hospital admission during pregnancy was 1.85 (95% CI 1.03–3.31). The IRR for perinatal death of the child was 3.43 (95% CI 0.57–20.53) before and 8.88 (95% CI 0.81–97.95) after stroke. Discussion and conclusions: Compared with stroke-free mothers, we found a higher incidence of pregnancy- and delivery-related complications in mothers with ischaemic stroke. Larger studies are needed to verify our results.

Return to work after ischemic stroke in young adults: A registry-based follow-up study
- 2018
-
In: Neurology. - 1526-632X. ; 91:20, s. e1909-e1917
-
Journal article (peer-reviewed)abstract
- 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.

Variability in quality of life 13 years after traumatic brain injury in childhood
- 2014
-
In: International Journal of Rehabilitation Research. - : Wolters Kluwer. - 0342-5282 .- 1473-5660. ; 37:4, s. 317-322
-
Journal article (peer-reviewed)abstract
- With the aim of describing variability in the long-term outcome of quality of life after neurosurgically treated pediatric traumatic brain injury, mostly self-reports of 21 individuals with mild or moderate/severe injury were gathered using Mayo-Portland Adaptability Inventory in telephone interviews 13 years aftyer injury. A majority of the participants reported brain injury-related problems. The median outcome on Mayo-Portland Adaptability Inventory was mild to moderate limitations. The variation within the moderate/severe group varied between relatively good outcome and moderate/severe limitations. Concentration, irritability, fatigue, and transportation were reported as the most problematic areas, whereas self-care was reported as well functioning. Societal participation appeared to be the best functional domain in this Swedish study. Examples of individual reports of the life-situation at various outcome levels were provided. Variability in outcome is large within severity groups, and research may gain by addressing both outcomes of the individuals and groups. Objective questions of outcome should be accompanied by questions of actual functioning in everyday life. To ensure long-term support for quality of life for those with remaining dysfunction after pediatric traumatic brain injury, healthcare systems should implement systematic routines for referral to rehabilitation and support.

Journal article (peer-reviewed)abstract
- Objective: To explore the cognitive long term outcome of two cohorts of patients neurosurgically treated for childhood traumatic brain injury (CTBI), either in 1987-1991 according to an older concept, or 1997-2001 with a stronger emphasis on volume targeted interventions. Research design and methods: Participants in the two cohorts were subject to an extensive neuropsychological assessment, 13.2 and 6.1 years post injury, respectively. In a between group design, assessment results of the two cohorts, n 18 and n 23, were compared to each other and to controls. Data were analyzed with multivariate analyses of variance. Results: Long-term cognitive deficits for both groups of similar magnitude and character were observed in both groups. Abilities were especially low regarding executive and memory function and verbal IQ. The cognitive results are discussed in terms of vulnerability of verbal functions and decreased executive control over memory-functions. Conclusions: There is a definite need for long term follow up of cognitive deficits after neurosurgically treated CTBI, also with the newer neurosurgical concept. Verbal learning and the executive control over memory functions should be addressed with interventions aimed at restoration, coping and compensation.

Journal article (peer-reviewed)abstract
- OBJECTIVE: To investigate the impact of time since injury on neuropsychological and psychosocial outcome after serious TBI in childhood or adolescence. METHODS: The subjects were eight patients with serious TBI sustained at a mean age of 14 years who had been assessed neuropsychologically at 1, 7 and 14 years after TBI. A retrospective longitudinal design was chosen to describe the development in six neuropsychological domains on the basis of the assessments. Psychosocial data were gathered from clinical knowledge and a semi-structured interview 14 years after TBI. RESULTS: Performance of verbal IQ shows a declining trend over the three assessments, that the performance of attention and working memory is low and that verbal learning is the cognitive domain which exhibits the largest impairments. The main psychosocial result is that three of the eight subjects went from a school situation with no adjustments to adult life with early retirement. CONCLUSIONS: Time since insult is an important factor when assessing outcome after TBI in childhood and adolescence and that assessment of final outcome should not be done before adulthood.

The journalistic preference for extreme exemplars: educational socialization, psychological biases, or editorial policy?
- 2024
-
In: JOURNAL OF COMMUNICATION. - 0021-9916 .- 1460-2466. ; 74:1, s. 48-62
-
Journal article (peer-reviewed)abstract
- Exemplars are central in news reporting. However, extreme negative exemplars can bias citizens' factual perceptions and attributions of political responsibility. Nonetheless, our knowledge of the factors shaping journalistic preferences for including exemplars in news stories is limited. We investigate the extent to which educational socialization, psychological biases, and editorial policy shape journalistic preferences for extreme negative exemplars. We field large-scale survey experiments to a population sample of journalism students, a nationally representative sample of citizens, and a representative sample of "young people" and obtain evaluations of news value, newsworthiness, and behavioral measures of the actual write-up of news articles. We find significant support for the role of editorial policy and limited support for the role of educational socialization and psychological biases. In a time where economic pressures and the proliferation of digital media potentially lead editors to prioritize clickbait, these findings suggest that structural biases in news coverage may be aggravated.
