    Background: Abnormal 12 lead electrocardiogram (ECG) findings and proposing its ability for enhanced risk prediction, majority of the studies have been carried out with elderly populations with prior cardiovascular diseases. This study aims to denote the association of sudden cardiac death (SCD) and various abnormal ECG morphologies using middle-aged population without a known cardiac disease. Methods: In total, 9511 middle-aged subjects (mean age 42 +/- 8.2 years, 52% males) without a known cardiac disease were included in this study. Risk for SCD was assessed after 10 and 30-years of follow-up. Results: Abnormal ECG was present in 16.3% (N = 1548) of subjects. The incidence of SCD was distinctly higher among those with any ECG abnormality in 10 and 30-year follow-ups (1.7/1000 years vs. 0.6/1000 years, P <0.001; 3.4;1000 years vs. 1.9/1000 years, P <0.001). At 10-year point, competing risk multivariate regression model showed HR of 1.62 (95% CI 1.0-2.6, P = 0.05) for SCD in subjects with abnormal ECG. QRS duration 110 ms, QRST-angle > 100', left ventricular hypertrophy, and T-wave inversions were the most significant independent ECG risk markers for 10-year SCD prediction with up to 3-fold risk for SCD. Those with ECG abnormalities had a 1.3-fold risk (95% CI 1.07-1.57, P - 0.007) for SCD in 30-year follow-up, whereas QRST-angle > 100 degrees, LVH, ER 0.1 mV and 0.2 mV were the strongest individual predictors. Subjects with multiple ECG abnormalities had up to 6.6-fold risk for SCD (P <0.001). Conclusion: Several ECG abnormalities are associated with the occurrence of early and late SCD events in the middle-age subjects without known history of cardiac disease. (C) 2018 The Authors.

    Kuormittavien elämäntapahtumien on useissa tutkimuksissa todettu lisäävän masennukseen sairastumisen riskiä, mutta tutkimustietoa niiden vaikutuksesta masennuksen kulkuun on tarjolla vähän. Tässä tutkimuksessa selvitettiin kuormittavien elämäntapahtumien vaikutusta nuorten depressioon sen päätetapahtumien ja oireiden kehityskulun osalta seuranta-aikana. Tutkittavilta kerättiin tietoa myös koetusta koulukiusaamisesta. Tutkittavat koottiin vuosina 1998-2001 nuorisopsykiatriseen erikoissairaanhoitoon hakeutuneista nuorista ja heidän verrokeista. Tutkittavia potilaita oli 218 ja heistä 148 osallistui kahdeksan vuoden seurantaan, verrokkeja oli 200. Mielenterveyshäiriöitä ja kuormittavia elämäntapahtumia selvitettiin sekä strukturoiduilla että subjektiiviseen arvioon perustuvilla haastatteluilla ja kyselyillä. Kiusaamiskokemuksia kartoitettiin takautuvasti kahdeksan vuoden seurantahaastattelussa. Tutkittavia masennuksen päätetapahtumia olivat masennuksen uusiutuminen, masennuksen kesto yli 25% seuranta-ajasta ja oirekehitystä kuvaavat latentit profiilit. Kuormittavien elämänkokemusten kumulatiivinen määrä lisäsi riskiä sairastua mielialahäiriöön, mutta vaikutusta masennuksen kulkuun ei havaittu. Vanhempien ero, alkoholismi ja psykiatrinen hoito sekä tutkittavan pahoinpidellyksi tuleminen lisäsivät riskiä sairastua masennukseen ja lieviin mielialahäiriöihin. Kiusatuksi tuleminen ala-asteella lisäsi masennuksen uusiutumisen riskiä. Kiusaamiskokemukset ala- ja yläasteella lisäsivät riskiä masennuksen kestoon yli 25% seuranta-ajasta. Seksuaalinen hyväksikäyttö seuranta-aikana lisäsi riskiä masennuksen huonolle kehityskululle, jossa toipuminen edistyy aluksi hyvin, mutta oireet vaikeutuvat vuoden seurannan jälkeen. Yksityiskohtaisempi kuormittavien elämänkokemusten vaikutusten tunteminen parantaa mahdollisuutta yksilöllisemmän hoidon suunnitteluun potilaille. Informaatiota voidaan käyttää depression uusiutumisen ja huonon kehityskulun riskissä olevien nuorten tunnistamiseen. Etenkin kiusattujen ja seksuaalista hyväksikäyttöä kokeneiden potilaiden tunnistaminen on tärkeää huomioiden niiden mahdollinen yksilötason vaikutus masennuksen kulkuun.

    Objective: To investigate long-term health-related quality of life (HRQoL) changes over time in younger compared to older disease-free breast cancer survivors who participated in a prospective randomized exercise trial. Methods: Survivors (aged 35-68 years) were randomized to a 12-month exercise trial after adjuvant treatment and followed up for ten years. HRQoL was assessed with the generic 15D instrument during follow-up and the younger (baseline age < 50) and older (age >50) survivors' HRQoL was compared to that of the age-matched general female population (n = 892). The analysis included 342 survivors. Results: The decline of HRQoL compared to the population was steeper and recovery slower in the younger survivors (p for interaction < 0.001). The impairment was also larger among the younger sur-vivors (p = 0.027) whose mean HRQoL deteriorated for three years after treatment and started to slowly improve thereafter but still remained below the population level after ten years (difference-0.017, 95% CI:-0.031 to-0.004). The older survivors' mean HRQoL gradually approached the population level during the first five years but also remained below it at ten years (difference-0.019, 95% CI:-0.031 to-0.0 07). The largest differences were on the dimensions of sleeping and sexual activity, on which both age groups remained below the population level throughout the follow-up. Conclusions: HRQoL developed differently in younger and older survivors both regarding the most affected dimensions of HRQoL and the timing of the changes during follow-up. HRQoL of both age groups remained below the population level even ten years after treatment. (c) 2021 The Authors. Published by Elsevier Ltd.

    Aim This Finnish regional birth-cohort study compared the school performance of very preterm and full-term children when they reached 11 years of age. Methods Teachers rated the educational abilities of 123 preterm children and 133 full-term controls at the age of 11 years as well as the support services they received. The children were all born in the Turku University Hospital between 2001 and 2005. In the preterm group, neurosensory impairments were confirmed at two years of corrected age, and full-scale intelligence quotient (IQ) was assessed at 11 years of age using the Wechsler Intelligence Scale, Fourth Edition. Results Educational abilities, including academic skills and classroom functioning, did not differ between the two groups after excluding the children with a full-scale IQ <70. However, 40% of the preterm group and 26% of the controls had received at least one support service (p = 70 and age-appropriate educational abilities do not exclude a significant need for support services in very preterm children at the age of 11 years.
